Description

Technical Field

[0001] The utility model relates to the technical field of construction hoists, in particular to an intelligent opening structure for a construction hoist door. Background Art

[0002] A construction hoist is an important device for transporting personnel and materials at high-rise building construction sites during building construction, and generally consists of a cage frame, guide rails, a drive system, safety devices, etc. Among its components, the hoist door plays a crucial role. It is not only a passage for personnel and materials to enter and exit, but also needs to ensure safety during operation.

[0003] At present, most construction hoist doors are controlled by a motor to wind a steel cable, but this design has some disadvantages.

[0004] Firstly, during the process of the motor winding the steel cable, a movable deflecting roller needs to be equipped. The friction of the deflecting roller and the rotation of the roller will generate relatively large noise, affecting the construction environment and possibly having an impact on the hearing of construction workers.

[0005] Secondly, when the motor winds the steel cable, the phenomenon of the steel cable getting disordered is likely to occur, resulting in incorrect winding of the steel cable, making it impossible to wind or release the steel cable, thus causing the door to fail to open and close smoothly and increasing the maintenance difficulty. Content of the Utility Model

[0006] The purpose of the utility model is to provide an intelligent opening structure for a construction hoist door, so as to solve the problems of disordered steel cable, complex cooperation of deflecting rollers and high noise existing in the use of construction hoist doors.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an intelligent opening structure for a construction hoist door, including a car, a car door slidably connected thereto, a motor arranged on the top of the car, the output end of the motor is connected with a speed reducer, the output end of the speed reducer is connected with a straight cylinder roller, one end of a lifting belt is connected with the straight cylinder roller, and the other end of the lifting belt passes through a deflecting roller arranged on the car and is connected with the car door.

[0008] Preferably, a connector is arranged at the connection part between the lifting belt and the car door.

[0009] Preferably, the deflecting roller is arranged on the car through a roller retaining sleeve.

[0010] Preferably, the car and the car door are slidably connected through a plurality of car door rollers.

[0011] Preferably, the width of the lifting belt is equal to the groove width of the straight cylinder roller.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Through a speed reducer, the high-speed rotation of the motor can be converted into a low-speed, high-torque output, thereby driving the straight roller to rotate. The straight roller can stably wind the sling, preventing it from getting tangled. While the sling has a strong load-bearing capacity, the material of the sling can absorb the vibration during the winding of the straight roller and the deflecting roller, which can increase the service life, reduce noise. The deflecting roller can prevent the sling from wearing and extend the service life.

[0014] 2. Through a connector, the sling can be connected to the car door. The roller collar can install the deflecting roller on the car, and also enable the sling to run stably on the deflecting roller. The car door roller can reduce the friction between the car and the car door, reduce vibration and noise. The width of the sling is equal to the groove width of the straight roller, which can enable the sling to be wound into the straight roller without arrangement, preventing it from getting tangled.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4As shown in the figure, the present utility model provides a technical solution: an intelligent construction elevator door opening structure, which includes a car 1, a car door 2 slidably connected thereto, a motor 3 disposed on the top of the car 1, a reducer 4 connected to the output end of the motor 3, a straight cylinder roller 5 connected to the output end of the reducer 4, one end of a lifting belt 6 is connected to the straight cylinder roller 5, and the other end of the lifting belt 6 passes through a steering roller 8 disposed on the car 1 and is connected to the car door 2. The reducer 4 converts the high-speed rotation of the motor 3 into a low-speed and high-torque output, thereby driving the straight cylinder roller 5 to rotate. The straight cylinder roller 5 can stably wind up the lifting belt 6 to prevent it from getting tangled. While the lifting belt 6 has a strong load-bearing capacity, the material of the lifting belt 6 can absorb the vibration during the winding of the straight cylinder roller 5 and the steering roller 8, which can increase the service life and reduce the noise.
