Description

Technical Field

[0001] The utility model relates to the technical field of construction elevators, in particular to a connection structure between a driving unit and a car of a construction elevator. Background Art

[0002] Construction hoists are a type of vertical transportation equipment widely used in construction. They are mainly used to transport personnel, materials and tools from the ground to different heights of buildings. With the acceleration of urbanization and the increase in high-rise buildings, the demand for construction hoists is increasing, and technology is also constantly innovating. Early construction hoists mainly relied on manpower or simple mechanical systems. With the development of motors and steel cable technology, electric construction hoists have gradually replaced traditional manual lifting equipment.

[0003] The connection method between the traditional construction elevator drive unit and the car is that the main beam and the cage are welded, and the top is connected to the drive trolley through hooks or ear plates. This not only requires more rollers when the main beam moves on the standard section, which is more expensive, but the main beam and the car are integrated and attached to the standard section through rollers. Most of the vibration will be transmitted to the car during movement, resulting in relatively loud noise. Utility Model Content

[0004] The utility model aims to provide a connection structure between a driving unit and a car of a construction hoist, so as to solve the problem in the above background technology that most of the vibrations are transmitted to the car during movement, resulting in high noise.

[0005] To achieve the above object, the utility model provides the following technical solution: a connection structure between a driving unit and a car of a construction hoist, comprising a car and a hanging ear fixedly connected to the top end thereof, a first load-bearing hole being opened on the surface of the hanging ear, and a rubber shock-absorbing wheel being installed inside the first load-bearing hole;

[0006] The car is connected to the driving main beam through a hanging ear, and an ear plate matching the hanging ear is fixedly connected to the driving main beam. A second load-bearing hole is opened on the surface of the ear plate, and the second load-bearing hole is connected to the rubber shock-absorbing wheel in the first load-bearing hole through a weighing pin shaft.

[0007] Preferably, the rubber shock-absorbing wheel includes a main roller, a rubber layer and an inner ring, the inner wall of the first load-bearing hole is provided with the main roller, the inner side of the main roller is provided with a rubber layer, and the inner side of the rubber layer is provided with an inner ring for carrying a weighing pin shaft.

[0008] Preferably, the inner ring and the second load-bearing hole have the same inner diameter and correspond to each other, the ear plate and the hanging ear are both provided with safety holes and correspond to each other, and a safety pin shaft passes through the inner side of the safety hole.

[0009] Preferably, the outer diameter of the safety pin is smaller than the inner diameter of the safety hole.

[0010] Preferably, a plurality of transverse rollers are arranged on the inner side of the driving main beam, and a plurality of vertical rollers are arranged on the outer side of the driving main beam.

[0011] Preferably, a shock-absorbing rubber pad installed on the car is provided at the bottom of the driving main beam.

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

[0013] 1. By setting up rubber shock-absorbing wheels and shock-absorbing rubber pads, the vibration generated by the contact between the car and the driving main beam can be reduced, thereby reducing noise. And through the design of an integrated driving main beam, the number of rollers used can be effectively reduced, reducing production costs.

[0014] 2. After the rubber shock-absorbing wheel is installed in the first load-bearing hole, the inner ring can be aligned with the second load-bearing hole so that the weighing pin can be inserted for connection. The weighing pin can be used as a supporting connection while also sensing the weight of the car, thereby preventing danger caused by excessive weight of the car. The safety pin is used when the weighing pin cannot work, which greatly improves safety. The safety pin does not bear load when the weighing pin is working normally, thereby ensuring the integrity of the safety pin when in use. BRIEF DESCRIPTION OF THE DRAWINGS
