At present, in the construction of the cover plate for the cable trench and the subsequent maintenance construction, it is necessary to use a tiger cart to transport the cover plate. Multiple construction workers lift the cover plate and place it on the tiger cart, and then arrange one person to push the tiger cart When transporting the cover plate, one person is needed to assist the cover plate during transportation. It can be seen that more manpower is required, and the cover plate is inconvenient to lift. Not only the construction efficiency is low, but also the personal safety of the construction workers is likely to be threatened during the lifting process.
In addition, because the cover is too heavy, it is easy to damage the cover during loading and unloading

Embodiment Construction
[0010] A heavy-duty cover lifting and lifting device, such as Figure 1 to Figure 4 As shown, it includes a frame 1 and a pair of wheels connected on the bottom surface of the tail of the frame 1. The tail of the frame 1 is provided with an upwardly folded stop frame 2, and the middle part of the block frame 2 is provided with a balance wheel set to control the balance state of the cover plate. 3. The balance wheel set 3 is connected to the frame 2 through a plurality of tubes 4 arranged in a matrix. One end of the tubes 4 communicates with the balance wheel set 3, and the other end runs through the frame 2 at the corresponding end. Each set of relative A steel wire rope 5 is threaded through the two pipe fittings 4, and the steel wire rope 5 passes through the balance wheel set 3. The part in the wheel set 3 is tightened on the balance wheel set 3 and can slide relative to the balance wheel set 3, and the part where the two ends of the steel wire rope 5 go out of the stop fra...

The invention relates to a heavy cover plate carrying and uncovering device. When a cover plate needs to be uncovered, only a plurality of hooks on a baffle frame need to be firmly hooked to the coverplate, wheels serve as supporting points, and the head of the vehicle body is pressed manually, so that the cover plate can be uncovered, as the part, which extends into a balance wheel set, of a steel wire rope is tightened on the balance wheel set and can slide relative to the balance wheel set, the inclined part of the cover plate can give action force to the hooks on the side when the cover plate inclines in the transportation process, so that the steel wire rope corresponding to the hooks is promoted to drive the balance wheel sets to roll, stress points at the two sides of the steel wire rope on the balance wheel set are adjusted through rolling of the balance wheel set, so that the balance state of the cover plate is adjusted, after the device reaches at the cover plate installation position, only the hooks need to be loosened manually and the cover plate can be easily installed, therefore, the cover plate can be uncovered, carried and installed only by one constructor, therebygreatly reducing the number of the constructors, the structure is simple, the construction cost is low, and the working efficiency of cover plate construction and maintenance is greatly improved.
Description
technical field [0001] The invention relates to a lifting and lifting device for heavy-duty cover plates. Background technique [0002] A heavy-duty cover needs to be placed at the opening of the cable trench to close the cable trench and prevent the cables in the trench from being damaged. At present, in the construction of the cover plate for the cable trench and the subsequent maintenance construction, it is necessary to use a tiger cart to transport the cover plate. Multiple construction workers lift the cover plate and place it on the tiger cart, and then arrange one person to push the tiger cart To transport the cover plate, one person is needed to assist the cover plate during transportation. It can be seen that more manpower is required, and the cover plate is inconvenient to lift. Not only the construction efficiency is low, but also the personal safety of the construction workers is likely to be threatened during the lifting process. In addition, because the cover...
