The technical problem to be solved by the present invention is to provide an electromagnetic lifting device for inspection shaft cover.

The technical solution of the present invention is: the inspection shaft cover electromagnetic lifting device, including four-wheel tractor head and electromagnetic sucker, the rear of the four-wheel tractor head is provided with a base extending backward, and the inner side of the base is provided with a horizontally rotatable The upper end of the vertical support is connected with a horizontal telescopic beam driven by a horizontal hydraulic cylinder and can slide horizontally along the slideway through a slideway. Swing up and down, the free end of the suspender is connected with a sling, the lower end of the sling is connected with the electromagnetic sucker, and a disc seat is arranged above the electromagnetic sucker, and the disc seat is provided with a central hole for the sling to pass through. There are three vertical shaft frames evenly distributed on the edge, and a rotatable vertical shaft is arranged on the vertical shaft frame. The upper end of the vertical shaft is fixed with a gear, and the lower end is provided with a horizontal locking rod. The outer ring gear that rotates on the shaft center matches the gear at the upper end of the vertical shaft, and the disc seat is provided with a hydraulic cylinder to drive the ring gear to drive the gear to rotate.

The technical effect of the present invention is: it has the advantages of simple structure, low cost, flexible operation and convenient use, and can replace a large number of manual operations to complete the disassembly and handling of manhole covers, save time and effort in operation, high operating efficiency and low energy consumption .

detailed description

As shown in Figures 1 and 2, the electromagnetic lifting device for the manhole cover includes a four-wheel tractor head 1 and an electromagnetic sucker 2. The vertical support 4 that rotates in the horizontal direction, the upper end of the vertical support 4 is connected with the horizontal telescopic beam 7 driven by the horizontal hydraulic cylinder 6 and can slide horizontally along the slideway 5 through the slideway 5, and the inner side of the horizontal telescopic beam 7 is hinged with a suspender 8. The boom 8 is driven by the lifting hydraulic cylinder 9 and can swing up and down along the hinge shaft. The free end of the boom 8 is connected with a sling 10, and the lower end of the sling 10 is connected with the electromagnetic chuck 2. There is also a circle above the electromagnetic chuck 2. Disc base 11, disc base 11 is provided with the center hole 12 that is used for sling 10 to pass through, and the edge of disc base 11 is evenly provided with three vertical shaft frames 13, and vertical shaft frame 13 is provided with rotatable vertical shaft 14, and the upper end of vertical shaft 14 A gear 15 is fixed, the lower end is provided with a horizontal locking lever 16, and the edge of the disc seat 11 is also provided with an outer ring gear 17 which is overlapped with the disc seat 11 and can rotate along the axis and cooperates with the gear 15 on the upper end of the vertical shaft 14 , The disc seat 11 is provided with a hydraulic cylinder 18 to drive the ring gear 17 to drive the gear 15 to rotate.

The outer end of the horizontal telescopic beam 7 is provided with a guide wheel 19, and the guide wheel 19 cooperates with the sling 10 to limit the displacement of the sling 10 in the horizontal direction.

The four-wheel tractor head 1 is also provided with a storage battery 20 for separately supplying power to the electromagnetic chuck 2 .

The disk seat 11 is also connected to the sling 10 through at least three auxiliary ropes 21 , and the connection points between the auxiliary ropes 21 and the lower end of the disk seat 11 are evenly distributed on the disk seat 11 .

When hoisting the well cover, the suction cup part is put on the well cover first, and because the sling is used to connect, when the disc is seated on the ground, it is supported on the ground by the vertical shaft on the vertical shaft frame. Continue to lower the sling, and the magnetic chuck will be in contact with the iron manhole cover. After electrification, the electromagnet attracts the manhole cover. After hoisting, the ring gear is driven by the hydraulic cylinder to drive the gear to rotate, so that the locking rod at the lower end of the vertical shaft swings inward and is held under the well cover, and the electromagnet can be powered off. Due to the short power consumption time of the electromagnetic chuck, the battery can be used continuously for a long time, and more manhole covers are disassembled and transported. The manhole cover can be transported on the base behind the front of the quad tractor.

A vertical connecting rod can be arranged at the center of the top surface of the electromagnetic chuck to connect with the sling, and the vertical connecting rod can pass through the center hole of the disc seat to facilitate assembly.
