Description

Technical Field

[0001] The utility model belongs to the technical field of construction elevators, and particularly relates to a construction elevator passage protection device. Background Art

[0002] Construction elevators, also known as construction elevators, building construction elevators or outdoor elevators, are commonly used construction machinery for carrying people and cargo in construction. As a highly dynamic environment with limited space resources, various building materials and temporary facilities need to occupy a large amount of space at the construction site. Moreover, as the construction progresses, the layout of the construction site continues to change.

[0003] The operation channel of the construction elevator, as the key path connecting the ground and high-altitude operations, is of vital importance to be unobstructed. However, due to the complexity of the construction environment, various obstacles often appear in the operation channel of the construction elevator. These obstacles may be temporarily stacked building materials, waste that has not been cleared in time, or new structures caused by sudden changes in the construction layout. During the high-speed operation process, if the cage of the construction elevator collides with these obstacles, it may not only cause serious damage to the construction elevator, but may even cause serious safety accidents.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] A construction elevator channel protection device, such as Figures 1 to 4 As shown, it includes a fence 1, on which a reinforcing rod 10 is arranged, and the reinforcing rod 10 can effectively enhance the structural strength of the fence 1.

[0024] The fence 1 is provided with a plurality of connecting ears 11 , each of which is provided with a strip hole 12 , so that the fence 1 can be connected to other structures by fasteners in conjunction with the strip holes 12 , thereby completing the installation and fixation of the fence 1 .

[0025] A mounting seat 2 is provided on the fence 1. In the present embodiment, there are two mounting seats 2, which are spaced apart from each other. A collision frame 3 is rotatably provided on the mounting seat 2. Specifically, a rotating shaft 6 is provided on the mounting seat 2, and there are two rotating shafts 6 which correspond one to one with the mounting seat 2. A connecting hole 7 is provided on the collision frame 3, and there are two connecting holes 7 which correspond one to one with the rotating shafts 6. The rotating shaft 6 passes through the connecting holes 7 and the two rotate in coordination, and the collision frame 3 can rotate around the rotating shaft 6.

[0026] The collision frame 3 has a collision portion 5 for colliding with an obstacle. The length of the collision portion 5 is greater than the width of the cage, thereby ensuring that the collision portion 5 will collide with the obstacle before the cage, thereby avoiding the situation where the obstacle misses the collision portion 5 and directly collides with the cage.

[0027] The collision frame 3 is located at the top or bottom of the cage. It should be noted that obstacles may appear in the operating channel when the cage is ascending or descending. Therefore, the collision frame 3 is located at the top or bottom of the cage to avoid the cage colliding with obstacles during the ascending or descending process and ensure safety.

[0028] A control switch for controlling the start and stop of the cage is provided on the mounting seat 2. When the collision frame 3 collides with an obstacle, the collision frame 3 rotates to trigger the control switch, and the control switch controls the cage to stop running.

[0029] It should be noted that during the operation process, if there is an obstacle in the operation channel, the collision frame 3 will first collide with the obstacle. When the collision frame 3 collides with the obstacle, a force will be generated to rotate the collision frame 3, thereby causing the collision frame 3 to rotate and trigger the control switch. The control switch controls the cage to stop running to avoid further collisions. This prevents the cage from colliding with obstacles during the operation of the construction elevator and causing damage, thereby ensuring the safe operation of the construction elevator.

[0030] Preferably, the control switch includes a travel switch 4. When the collision frame 3 rotates, the collision frame 3 can press the travel switch 4. The collision frame 3 presses the travel switch 4 to trigger the travel switch 4, so that the control switch controls the cage to stop running.

[0031] As another solution, the control switch may also be a proximity switch, and the collision frame 3 is rotated to approach the proximity switch, thereby completing the triggering of the proximity switch.

[0032] A reset member for resetting the collision frame 3 is disposed on the mounting seat 2 . Specifically, the reset member includes a tension spring 8 , one end of the tension spring 8 is connected to the mounting seat 2 , and the other end of the tension spring 8 is connected to the collision frame 3 .

[0033] It should be noted that when the collision frame 3 collides with an obstacle, a force is generated to rotate the collision frame 3, thereby causing the collision frame 3 to rotate. After the collision frame 3 rotates, the tension spring 8 is deformed, and due to the limitation of the obstacle, the collision frame 3 is usually in a relatively stable state after the collision. When the obstacle is cleared, the elastic restoring force of the tension spring 8 causes the collision frame 3 to rotate and reset.

[0034] It should be further explained that after the collision frame 3 is reset, the travel switch 4 is reset and the cage can start to operate normally.

[0035] A limiting member for limiting the position of the collision frame 3 is provided on the mounting seat 2, and the limiting member includes a fixing screw 9. In the present embodiment, there are two fixing screws 9 and they correspond one to one with the mounting seat 2. The fixing screws 9 are threadedly connected to the mounting seat 2, and the outer surface of the mounting seat 2 can abut against the outer side wall of the fixing screw 9, so as to limit the collision frame 3, thereby ensuring the stability of the collision frame 3 when it does not collide with an obstacle.

[0036] The working principle of the utility model is as follows:

[0037] During the operation, when the collision part 5 of the collision frame 3 collides with an obstacle, a force is generated to rotate the collision frame 3. The collision frame 3 rotates around the rotating shaft 6 and presses the travel switch 4, which triggers the control switch and controls the cage to stop running. The tension spring 8 is deformed under the action of the tension force. After the obstacle is cleared, the elastic restoring force of the tension spring 8 causes the collision frame 3 to rotate and reset. The collision frame 3 moves away from the travel switch 4, and the travel switch 4 is reset.

[0038] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
