Problems solved by technology

The suspension device usually enters the machine room through the shaft opening (functional opening) on ​​the top of the shaft, and the top of the shaft opening has a ring frame 20-2 exceeding 5cm (national standards; metal plates, wood boards, and cement can be used to form a circle. ), the force on the top of these ring frames will cause severe deformation of the ring frame, so when used as a support point during testing, defects such as inaccurate test data will occur

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0026] The inventors have found that the hoistway roof 20 is made of reinforced concrete, and the area on the other side of the bottom end of the hoistway mouth 20-1 corresponding to the ring frame is a horizontally arranged plane, which can withstand large forces; it can be used as a force measuring device the force point.

[0027] According to this idea, in the force measuring device for clamping the elevator suspension provided by the present invention, the fixed support 9 is located under the hoistway mouth and is connected with the suspension device 1 through the lifting belt 2, and the length of the fixed support is greater than the hoistway mouth. So that the two ends of the fixed support can rest on both sides of the hoistway mouth; the force measuring module 8 with the signal processing unit i...

Abstract

The invention relates to a force measuring device for clamping an elevator suspension device. The aim is to provide the force measuring device for clamping the elevator suspension device, and the force measuring device has the characteristics of high universality, simplicity in installation and reliability in measurement. According to the technical scheme, the force measuring device for clamping the elevator suspension device is characterized in that the device comprises a fixed support which is connected with a suspension device through a lifting belt and can be placed at the bottom end of ashaft opening in a blocking mode, a force measuring module installed on the upper surface of the fixed support to measure the stress condition of the suspension device and provided with a signal processing unit and an anti-falling module used for connecting the fixed support with the suspension device to prevent the fixed support and the clamping module from falling accidentally during installation.

Description

technical field [0001] The invention relates to a force-measuring device for clamping an elevator suspension device, in particular to a dynamic force-measuring device for clamping a suspension device for quantitative evaluation of elevator safety. Background technique [0002] The elevator suspension device is mainly steel wire rope and composite steel belt, which interacts with the traction wheel to generate traction force to drive the car and counterweight on both sides of the suspension device to move up and down. When elevator maintenance and safety inspectors test the traction force, they mainly determine whether it meets the standards and inspection requirements in a qualitative way, which cannot quantitatively detect the traction force. The tension difference of the suspension devices on both sides of the traction sheave can determine the balance coefficient, which is also an important parameter for elevator inspection. The detection of traction force and balance coe...
