Description

A heavy-duty cover lifting device

technical field

The utility model relates to a lifting device for a cover plate, in particular to a lifting device for a cableman's well cover plate.

Background technique

With the acceleration of power grid and urbanization construction, the number of cable transformation projects is increasing, and there are more and more cable lines. The large increase in the number of cable manholes has led to an increasing workload in the past to manually lift the cable manhole covers in the work of cable line maintenance, pre-testing, fault point finding, and path positioning. At the same time, the tools used to manually lift heavy-duty manhole covers are crude (crowbars, bamboo sticks, iron brazing, ropes, etc.), with a low safety factor, and operators are easily injured during the lifting process. There are many operating personnel used in the well cover process, and the operating time is longer.

Since the cable cover plate is a load-bearing cover plate, and concrete pointing has been used, the friction between the cover plates is large, and it is difficult for the operator to lift the cover plate, which brings great difficulties to cable line maintenance, pre-test, fault point finding, path positioning, etc. Great inconvenience.

The beam is an I-shaped rail, and a monorail trolley is arranged on the beam. A lever hoist is connected under the monorail trolley. The lever hoist is a chain lever hoist, and a cover plate is hung under the hook of the lever hoist to lift The cover plate lifting mechanism includes two equal-length steel wire sleeves connected to the hook at one end and a hook plate connected to the other end of the steel wire sleeves by a shackle and capable of hooking the pull ring of the cover plate.

On the basis of adopting the above technical scheme, the utility model can also adopt the following further schemes:

The hook plate is plate-shaped, and the hook plate includes an upper inclined plate, a middle vertical plate and a lower horizontal plate perpendicular to the vertical plate, and the outer surface of the joint between the inclined plate and the vertical plate, as well as the vertical plate and the horizontal plate The outer surface of the joint of the board is welded with fixed steel bars.

The lower ends of the beam are respectively welded with tubular parts, and the two vertical rods are respectively inserted into the tubular parts at both ends of the beam and fixed with long screws.

The length of the beam is 1300mm-1700mm.

The length of the vertical rod is 1400mm-1800mm.

The length of the bottom plate is 600mm-1000mm.

The universal pulley is provided with a braking device.

Due to the adoption of the technical solution of the utility model, the utility model adopts a mechanical lifting device to replace the traditional manual operation mode, which improves safety while reducing workload. The hoisting device of the utility model adopts a door-shaped structure, uses a monorail trolley to connect the lever block, the lever hoist hooks the cover plate and lifts it, and uses the monorail trolley to translate the cover plate, which is simple and convenient to operate and has strong practical applicability. At the same time, the hook plate adopted by the utility model is plate-shaped, which increases the contact area and makes the safety higher.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The utility model comprises a door-shaped frame 1, which adopts a steel structure and has a heavier overall weight. The door-shaped frame 1 includes a cross beam 2 on the top and two vertical bars 3 at both ends of the cross beam 2. The lower ends of the cross beam 2 are respectively welded with tubular parts 21, and the two vertical bars 3 are respectively inserted into the tubular parts at the two ends of the cross beam. 21, and fixed with a long screw, only need to operate the long screw during installation and disassembly, easy to disassemble, so although the overall quality is heavy, but its individual parts can be disassembled, making the handling and carrying process light, including Hoist described below and monorail dolly 10 all can be disassembled.

The bottom of the vertical bar 3 is provided with a base plate 4 perpendicular to the vertical bar 3, the two ends of the base plate 4 are provided with universal pulleys 5, and a reinforcing bar 6 is provided between the two ends of the base plate 4 and the vertical bar 3, and four universal pulleys are provided. The directional pulley 5 allows the lifting device to move freely and adjust its position. At the same time, the universal pulleys are all equipped with brakes. After the brakes are fixed in position, the operation process will not be affected, with strong applicability and high safety;

The crossbeam 2 is an I-shaped steel rail, and a monorail trolley 10 is arranged on the crossbeam 2, and the monorail trolley 10 can move in parallel on the crossbeam 2. A lever hoist 11 is connected under the monorail trolley 10, the lever hoist 11 is a chain lever hoist, and a cover plate lifting mechanism is hung under the hook 12 of the lever block 11, and the cover plate lifting mechanism includes one end connecting Two equal-length wire sleeves 13 on the suspension hook and utilize shackle 20 to be connected to the suspension hook plate 14 that can catch the cover plate draw ring on the wire sleeve 13 other ends.

The hook plate 14 is plate-shaped, and the hook plate 14 includes an upper slant plate 141, a middle vertical plate 142 and a lower horizontal plate 143 perpendicular to the vertical plate 142, and the connection between the slant plate 141 and the vertical plate 142 A fixed steel bar 144 is welded on the outer surface of the joint and the joint of the vertical plate 142 and the horizontal plate 143 . The plate-shaped hook plate increases the contact area with the pull ring of the cover plate, so that the force-bearing area is larger, and the hook plate will not be broken or other dangers due to excessive force, which increases safety.

The length of the beam 2 is 1300mm-1700mm, within this size range the cover plate can be moved outside the hole area covered by the cover plate.

The length of the vertical bar 3 is 1400mm-1800mm, and the lifting of the cover plate within this size range can better operate the hand hoist, and also makes there be enough work space.

The length of the bottom plate 4 is 600mm-1000mm, which is convenient for the movement of the universal pulley, and the stability of the overall structure is better.
