Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an ultra-large load-bearing 8:1 freight elevator. Background Art

[0002] A freight elevator is an elevator device mainly used for transporting goods and is widely used in various places where vertical transportation of goods is required.

[0003] In the prior art, in order to ensure the quality of a freight elevator during operation, a glue-locking device is usually installed on the car top, such as the car top glue-locking device disclosed in the technical solution of CN202221525661.2. The car top glue-locking device includes a glue-locking seat, which includes a transverse car top glue-locking device and a longitudinal car top glue-locking device fixedly welded to the top of the front surface of the transverse car top glue-locking device. One side of the front surface of the transverse car top glue-locking device and one side of the longitudinal car top glue-locking device are both installed with shock-proof support feet. A fixing bolt passes through the middle of the shock-proof support foot. An adjusting bolt is installed on one side of the shock-proof support foot. An anti-loosening bolt is installed on one side of the adjusting bolt. Both the adjusting bolt and the anti-loosening bolt are threadedly connected to the fixing bolt. One of the anti-loosening bolts is fixedly installed on the longitudinal car top glue-locking device, and the other anti-loosening bolt is fixedly installed on the transverse car top glue-locking device. The above structure utilizes the rubber pads of the shock-proof support feet to contact and cooperate with the car frame columns to achieve the purpose of shock absorption and noise reduction.

[0004] However, in this technical solution, the position of the shock-absorbing support foot is adjusted by means of a fixing bolt, an adjusting bolt and an anti-loosening bolt. This setting method allows the shock-absorbing support foot to have a certain distance gap from the rubber clamping seat, resulting in the rubber clamping seat failing to directly support the shock-absorbing support foot. When the shock-absorbing support foot is subjected to force, the fixing bolt connecting the shock-absorbing support foot is easily deformed and bent, causing the rubber pad on the shock-absorbing support foot to not cooperate well with the car frame column, affecting the use effect and service life of the rubber clamping device.

The freight elevator frame 1 includes four car frames 100 and a chassis 104 arranged from front to back. The car frame 100 includes two car frame columns 101, a car frame upper beam 102 and a car frame lower beam 103. The left and right ends of the car frame upper beam 102 are respectively connected to the upper ends of the two car frame columns 101, and the left and right ends of the car frame lower beam 103 are respectively connected to the lower ends of the two car frame columns 101.
