A double-layer crawler-type cargo climbing device and method for climbing stairs

Abstract

The invention provides a double-layer crawler-type load-carrying stair climbing device and a stair-climbing method, which belong to the technical field of building construction equipment. The invention includes a double-layer crawler mechanism, a horizontal loading mechanism, an auxiliary outrigger mechanism and a base plate mechanism; the auxiliary outrigger mechanism is located at the front of the stair climbing device, can be rotated, lowered and stowed, and can lift the front of the device to facilitate the double-layer The crawler mechanism climbs stairs; the double-layer crawler mechanism is located on both sides of the base plate mechanism, and is driven by a motor to realize the operation of climbing stairs; a horizontal loading mechanism is installed above the base plate mechanism, and the rear end of the horizontal loading mechanism is connected to each other through the lifting screw and the lifting screw nut. Cooperate with the height adjustment to ensure that the heavy objects are always stable and there will be no collision or slippage. The invention has a high degree of automation, does not need to manually carry heavy objects upstairs, saves time and labor, has good safety and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a double-layer crawler-type load-carrying stair climbing device and a stair climbing method. Background technique [0002] During the construction process, tower cranes, cranes, crank trucks and other machinery are usually used to operate or use flat push-pull carts to take construction elevators to realize the operation of heavy objects upstairs. However, the existence of the tower crane often affects the closing of the basement roof, the closing of the tower wall or the curtain wall, etc., so it needs to be dismantled as soon as possible to avoid delaying the construction period; , need to have a certain erection space and hoisting hole, and the height of carrying goods upstairs is limited in this way, which is often difficult to apply in super high-rise buildings.

AI Technical Summary

Problems solved by technology

However, the existence of the tower crane often affects the closing of the basement roof, the closing of the tower wall or the curtain wall, etc., so it needs to be dismantled as soon as possible to avoid delaying the construction period; , need to have a certain erection space and hoisting hole, and the height of carrying objects upstairs is limited in this way, which is often difficult to apply in super high-rise buildings

[0003] When the tower crane cannot be demolished and the construction elevator can’t be reached, it is often only possible to use tools such as chains down from the stairwell to carry heavy objects up the stairs manually, which is time-consuming and laborious, and it is difficult to turn on the stair platform. Often subject to bumps and wear during construction

Although there are various stair-climbing trolleys on the market, most of them are manual push-pull trolleys with low degree of automation and low practicability. The stability of heavy objects in the process of going upstairs is poor, which may easily lead to cargo collision or slipping.
