(PM of the Russian Federation No. 144644, IPC A01K51 / 00, published on 08.27.2014). The disadvantage of this device is that it has a complex structure, cumbersome and inconvenient in the maintenance of hives in a small farm, served, as a rule, by one person.

The closest in design to the claimed device (prototype) is found on the INTERNET (https://www.pchelomatka.ru/vitrina_preview-488.html) “Lifting-sliding device for 2 hive hives” by V. Fedorenko, consisting of two detachable parts: guide rails with two sliding legs and a movable carriage with a lifting mechanism in the form of screws, allowing you to lift the upper case and roll it back. On each hive, on the sides of the lower case, guide bushes are fastened, into which pins of the guide rails are inserted. On the guide rails there is a movable carriage, which engages with four corners, previously fixed on the upper case of the hive. The raising of the upper case takes place using the rotation of the cap head with a hand rotor or screwdriver.

The disadvantage of the prototype is the difficulty of lifting and moving the case by one person, the possibility of lifting the hive body of only one certain size, due to the fixed width of the guide rails, the stationary installation of the device, in addition, it is not possible to conveniently transport the device to a new place.

The objective of the utility model is to simplify operation, expand the technological capabilities of the hoist-and-slide device for servicing multihull hives, consisting in the possibility of using the device to work with hives of various sizes, by one person and the possibility of convenient transportation (compactness).

The problem is solved due to the implementation of the lifting-sliding device in the form of two frames of variable width, their structural design, mutual placement, as well as the structural design of the lifting mechanism, and folding device design.

The technical result from the use of the proposed utility model is to expand the technological capabilities of the device, due to the possibility of working with hives of various sizes, to increase the mobility of the device, as well as to increase the convenience of its use.

The essence of the utility model consists in the fact that a mobile hoisting and retracting device for servicing multihull hives contains two U-shaped metal frames of variable width: a large fixed and a small mobile one, each of which consists of two equal symmetrical parts, the short sides of which are interconnected when using detachable joints with the possibility of mutual movement and fixation in the desired position using couplings. In this case, the large fixed lower frame is equipped with a support column fixed in the middle part of its short side with the possibility of rotation through 270 ° in the vertical plane. The small upper frame is mounted on the long parallel sides of the lower frame with the possibility of horizontal movement along them by means of rollers. On the upper movable frame there is a lever-lifting mechanism with an upper position lock and limiters to prevent sliding of the upper movable frame in the horizontal plane.

The essence of the proposed utility model is illustrated by graphic materials:

In FIG. 2 - Lifting and lever mechanism of the device;

In FIG. 3 - Device, top view;

In FIG. 4 - The device is folded.

The proposed portable lifting and sliding device for servicing multi-tiered beehives consists of two U-shaped metal frames of variable width: the lower large fixed frame 1 and the upper small movable frame 2. Each frame consists of two symmetrical semi-frames, the short sides of which are interconnected by couplings 3, with the possibility of mutual movement and fixation in the desired position (Fig. 3). This design of the sliding frames allows you to use the proposed device for different sizes of hive bodies. A vertical metal support post 4 is pivotally mounted on the short (end) side of the lower fixed U-shaped frame 1, and a horizontal bar 5 is fixed on the free lower end of it. The support post 4 has the ability to be height-adjusted and locked in position using the adjusting screw 6 The free ends of the lower stationary U-shaped frame 1 are equipped with wheels 7 for easy transportation of the device. The upper movable frame 2 is provided with rollers 8 for movement along the lower frame. On the upper movable frame 2 there is a lifting lever mechanism with the possibility of fixing in the upper position (Fig. 2). The lifting lever 9 of the lever lifting mechanism has a U-shape of variable width, with the possibility of connecting its short side with the help of a coupling 3, axial movement and fixing in the desired position (Fig. 3). The lifting lever 9 is pivotally mounted on the upper frame and is equipped with spring-loaded hook-clamps 10 with a cable drive to the handle 11, symmetrically placed on its opposite sides. There is a stop 12 on the moving part of the lifting mechanism (Fig. 1, 2). A hook 13 is placed on the support post 4 of the lower frame 1 to hold the upper frame 2 in the folded state of the device (Fig. 1, 4). To ensure the operation of the proposed mobile lifting and sliding device, on the lower case 14 of the multihull hive, on its opposite lateral surfaces, in the upper part, guide shelves 15 are rigidly fixed for installing the lower fixed frame 1 of the device. On the lateral surfaces of the upper hull body 16 of the hive, in its lower part, just as rigidly, symmetrically to the shelves 15 of the lower case, shelves 17 are fixed for stopping the movable part 18 of the lifting-lever mechanism (Fig. 1)

In the inoperative state of the device, both U-shaped frames can be folded in the same plane and moved using wheels 7 located on the free ends of the large U-shaped frame. The compactly folded device can be transported in the trunk of a car (Fig. 4), (photo 6).

The device operates as follows.

The long (side) sides of the large fixed frame 1 are placed on the side guide shelves 15 of the lower housing 14 of the multi-hive hive. The width of the device is adjustable in the couplings 3. The metal vertical strut 4 is rotated 90 ° relative to the horizontal frame and is mounted on a horizontal bar 5 mounted on the ground, providing an additional fulcrum (Fig. 1, photo 1). The vertical strut 4 is fixed at the desired height. The upper U-shaped frame 2 is mounted on the lower U-shaped frame 1 outside the hive body and moves on rollers 8 in the direction of the hive body until the stop 12 contacts the shelf 17 (Fig. 1), (photo 2). The lever 9 is mixed down to engage hooks 10 with the movable frame 2. The lifting lever 9 moves the movable part 18 of the mechanism up, which, resting against the shelf 17, raises the upper case to the required height (3-4 cm) (photo 5). In the upper position, the mechanism is fixed by hooks 10. The upper frame 2 is moved on rollers 8 along the lower frame 1 in the direction of the support 4, providing access from above to the lower case 14 of the hive for its maintenance. At the end of the maintenance of the hive, the upper movable frame 2 is pushed onto the lower hive housing 14, the hooks 10 are released from the mesh by the handle 11, and by smoothly raising the lever 9, the upper hive housing 16 is lowered onto the lower housing 14, collecting the hive in its original state. The upper frame 2 moves along the lower frame 1 towards the support 4 to the starting position.

To move the device outside the apiary, the upper movable frame 2 is removed from the lower fixed frame 1, then the lower frame is removed, the rack 4 is rotated 270 ° in the vertical direction, the horizontal bar 5 enters into special holes in the frame 1. On a folded large frame 1 with wheels 7, a small frame 2 is laid on top and fixed on it with the help of a hook 13 placed on the rack of the large frame 1 (Figs. 1, 4), (photo 6). The device is ready for transportation.

The proposed device is lightweight, compact, quickly installed and removed from the hive, the work does not require large physical loads, just one person to maintain. It can be used to lift and move the hulls of multihull hives of various sizes, due to the variable (adjustable) width of the U-shaped frames, with any number of hulls. You can use several devices for simultaneous access to all buildings of the multihull hive. It is possible to move the device when it is folded on wheels and to conveniently transport it in the trunk of a car, due to the convenient compact folding of the lift-and-slide device.

Thus, the problem facing the utility model is solved.
