Description

Technical Field

[0001] The invention relates to the technical field of elevator installation, and in particular to an internal waterproof, dustproof and anti-settling device during elevator installation. Background Art

[0002] The shock-absorbing protection structure for preventing the impact load settlement of elevators disclosed in Chinese patent document CN111997099B can control the settlement problem of the elevator foundation under repeated load impact, and improve the stability of the elevator foundation. The present invention can well reinforce the connection between the elevator shaft and the elevator foundation. When the elevator shaft moves, there can be good buffering, and a cooperative effect is generated between the shaft and the foundation. Whether it is lateral movement or vertical movement, it can achieve a good reinforcement effect. The buffer friction built-in blanket in the present invention uses high damping rubber and manganese steel support columns to interact with each other. Extrusion shock absorption, especially the design of the reserved area for variable-caliber vibration displacement buffer, can make the buffer friction built-in blanket and manganese steel support column extrusion shock absorption more efficient under repeated load impact, provide good buffering when the elevator is in use, offset the impact force generated during use, make the force more uniform, and have a significant anti-settlement effect. The present invention can prevent the foundation of the installed elevator from settling or reduce the settlement distance, avoid safety hazards when the elevator is in use, adapt to the development direction of the renovation of elevators in existing buildings in old urban areas, improve the stability of elevator use and prevent the settlement of the elevator foundation caused by repeated load impact.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The internal waterproof, dustproof and anti-settling device of the elevator during installation can raise and lower the adjustable support column by rotating the stud, connecting the hollow column, adjusting the support column, reinforcing the hollow column and the water-supplying stone rod. In this way, the position of the anti-settling lower plate can be adjusted according to the installation position during installation, thereby reducing the tilt of the anti-settling lower plate due to different foundation hardness after the anti-settling support column is inserted into the ground, thereby increasing the horizontality of the anti-settling lower plate during installation. The water-supplying stone rod and the water-supplying stone plate can be used to absorb the underground water accumulation, thereby avoiding the accumulation of water at the installation position when there is a lot of water in the rainy season after installation, thereby avoiding the corrosion of the adjustable support column and the anti-settling support column by the accumulated water, thereby improving the overall service life of the device. At the same time, the dust-proof plate can wrap the anti-settling lower plate, the shock-absorbing middle seat and the anti-settling upper plate, thereby increasing the dust-proof effect of the device.

[0018] (2) The internal waterproof, dustproof and anti-sedimentation device of the elevator during installation can limit the inspection door through the arrangement of the inspection door, telescopic rod, limit spring, movable plate and limit block. In this way, after the water supply slab absorbs water, the water supply slab can be taken out and dried or replaced by simply canceling the limit on the inspection door, thereby avoiding the situation where the water inside the water supply slab cannot be dissipated and the water absorption efficiency of the water supply slab is poor, thereby ensuring the waterproof effect of the device. In addition, such a limiting method is relatively simple and easy for workers to operate, which not only reduces the labor intensity of workers, but also improves the efficiency of workers in replacing the water supply slab.

[0019] (3) The internal waterproof, dustproof and anti-settling device of the elevator during installation can connect the anti-settling lower plate with the anti-settling upper plate and the foundation by installing the side plates, the guide vertical plates, the sliding connection sleeves, the stabilizing columns, the stabilizing sleeves, the first damping support springs and the fixing boxes. Such connection is a flexible connection, which can reduce the pulling on the foundation and avoid damage to the foundation due to stress. At the same time, after the anti-settling lower plate and the anti-settling upper plate are connected to the foundation, the settlement of the anti-settling lower plate can be reduced, thereby improving the anti-settling effect of the device.

When the position of the anti-settling lower plate 1 is horizontal, the connecting mounting plate 711 is fixed to the wall of the foundation through fasteners such as expansion bolts, so that the installation of the device can be completed. When water accumulates at the bottom of the anti-settling lower plate 1, the water enters through the water inlet holes on the adjusting support column 403. The interior of the hollow column 404 is reinforced, and then water is sucked into the water supply stone plate 407 for storage through the water supply stone rod 405, thereby reducing the accumulation of water at the bottom of the anti-settling lower plate 1. When the water supply stone plate 407 needs to be replaced, the toggle rod 506 is moved, and the movement of the toggle rod 506 drives the movable plate 504 to move, and the movement of the movable plate 504 drives the limit block 505 to move. After moving the limit block 505, the limit of the inspection door 501 and the anti-settling upper plate 3 can be cancelled, and then the inspection door 501 can be opened to take out the water supply stone plate 407.
