Abstract

The invention relates to vehicles, and more specifically to vehicles for the transport of long loads. The aim of the invention is to increase reliability by redistributing the loads on the frame. The goal is achieved by the fact that in a device containing a frame with supports for the cargo being transported, one of which consists of a two-arm lever with a counterweight and a rack, on the upper end of which, by means of an axis, a bed with articulated additional pillars is mounted on frame with the help of a link and an additional two shoulders arm with the formation of a parallelogram. At the same time, the free ends of the main and additional two-arm arms are connected by means of a pull rod, adjustable in length. 3 hp f-ly. beat

Description

The invention relates to vehicles, namely vehicles for the transport of long loads. .

The purpose of the invention is to increase reliability by redistributing the loads on the frame.

1 shows a schematic of a vehicle, a general view: in FIG. 2, a node I in FIG. 1; Fig. 3 is a view along arrow A in Fig. 2 (side view of a support); figure 4 - section bb in figure 2; FIG. 5 is a view along arrow B of FIG. 2; figure 6 - node II in FIG. 3

The vehicle consists of a frame 1 with supports 2, 3 and 4 for the load being transported 5. Support 3 includes a rack 6, hinged to frame 1 with the help of a hinge link 7 and an additional two-arm lever 8 to form a parallelogram, and a lodgement 9, hinged on the rack 6 with the axis 10 and the additional racks 11 with the formation of a parallelogram. At the upper end of the post 6 are mounted spring-loaded stops 12, consisting of a cup 13, lugs 14, springs 15, axes 16 and a roller 17. One of the uprights 11 and link 7 are connected by means of a leash 18 sticking from housing 19, stem 20 , springs 21 and sleeves 22 and 23. The double-arm lever B is connected to the main two-arm lever 25 by a counterweight 26 by means of the coupling 24, the counterweight 26 communicates with the adjustable stop 27 and through the roller 28 - with the guide 29,

The vehicle is operated as follows.

Before loading, the counterweight 26 is in its lowest position and interacts with the stop 27, and the loco: the jam 9 with the stand 6 is in its extreme upper position. When loaded by the force of the weight of the load 5, the cradle 9 with the stand 6 is lowered and the counterweight 26 rises. Then the load 5 is fixed on the support 4 from longitudinal and transverse (vertical and lateral) movements, and on the support 2 - from transverse movements

The leash 18 ensures smoothness of the pull of ha and is made adjustable by the d-pitch of the pillar 6. When moved.

nor stand 6 upward leash 18 reproach-3. The vehicle under item 1,

The stem 20 through the sleeve 22 is distinguished by the fact that

compresses the spring 21. When moving the item is attached to the front hinge

stand 6 down the leash 18 lengthens: and the brush 20 through the sleeve 23 compresses the spring 2),

The spring-loaded stop 12 eliminates the swinging of the cradle 9 around the axis 10. The presence of the roller 28 and the guide 29 excludes lateral movements of the counterweight 26, and consequently, eliminates the additional loading of the two-arm lever 25.

The presence of racks 1I eliminates the longitudinal movement of the lodgement 9 relative to the load when moving the rack 6, which ensures the safety of the surface of the cargo 5.

The adjustment of the initial position of the lodgement 9 in height is carried out by adjusting the stop 27 and changing the length t - 1 to 24.

Claims (2)

1. A vehicle for the transport of long loads containing a frame with three supports for the cargo being carried, the middle of which includes a rack with a lodgement at the upper end mounted on the frame with the possibility of longitudinal vertical movement hinged on the frame with the possibility of rotation in the vertical plane of the double whose lever, on one shoulder of which a counterweight is fixed, and the other connected with the stand, is about 1 a-th er so that, in order to increase reliability by redistributing the loads on the frame, it is equipped with a hinge link and an additional two-arm lever hinged on the frame so that it can be rotated in a vertical longitudinal plane, with one shoulder of the additional two-arm lever connected to the other shoulder of the main two-arm lever, and the other shoulder and hinge link to the hinge image with it and frame parallelogram mechanism. 2. A vehicle of claim. I, distinguished by the fact that but can be rotated in a vertical transverse plane and displaced in the longitudinal direction and is spring-loaded with respect to the stand. 2 to 4, a vehicle according to claim I, characterized in that a guide is mounted on the frame, in which a roller mounted on the counterweight is located. 3s fi 2 Vida 25 fae. ff (rig, 3 View B / 7g f / 7 //.
