Description

Technical Field

[0001] This utility model relates to the field of elevator brake inspection technology, specifically to an elevator brake inspection device. Background Technology

[0002] The brake is a crucial component ensuring the safe and normal operation of an elevator. Under normal circumstances, after the elevator traction machine stops rotating, the car's stationary state is maintained by the brake. If a sudden power outage or electrical safety device suddenly disconnects during elevator operation, the reduction in elevator speed and its eventual stop depend entirely on the brake. An elevator brake testing device is an instrument that can detect whether the elevator's braking capability is up to standard. The device consists of a handheld testing terminal and a front-end rotating wheel. During testing, the front-end rotating wheel is rotated close to the wire rope, and the wire rope drives the front-end rotating wheel to rotate, thus performing the testing operation.

[0003] However, existing elevator brake testing equipment is inconvenient for disassembling and assembling the front wheel, and the positioning effect of the front wheel during disassembly and assembly is not good enough. Furthermore, the heat dissipation effect of the device is not good enough. Therefore, it does not meet the existing requirements. In response, we propose an elevator brake testing device. Utility Model Content

[0004] The purpose of this utility model is to provide an elevator brake testing device to solve the problems mentioned in the background art, such as the inconvenience of disassembling and assembling the front wheel, the poor positioning effect of the front wheel during disassembly and assembly, and the poor heat dissipation effect of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator brake inspection device, comprising a main body, a display screen on the outer surface of the main body, a connecting hole on the outer surface of one end of the main body, a heat sink plate on the other end of the main body, a connecting shaft on one side of the heat sink plate, a rotating wheel on one end of the connecting shaft, a toothed groove on the inner side of one end of the connecting shaft, a reinforcing plate on the inner side of the rotating wheel, a connecting gear on one side of the reinforcing plate, the connecting gear corresponding to the toothed groove, a plug rod on the inner side of the connecting gear, the plug rod engaging with the connecting shaft, connecting grooves uniformly distributed on the outer surface of the connecting shaft, springs uniformly distributed on the inner side of the connecting grooves, a first positioning block on one end of the spring, a pressing ring on one side of the first positioning block, a second positioning block on the inner side of one end of the pressing ring, the second positioning block being threadedly connected to the pressing ring, a heat-conducting plate on the outer surface of the connecting shaft located inside the heat sink plate, and heat sink fins on the outer side of the heat-conducting plate.

[0006] Preferably, one end of the insertion rod is completely in contact with the outer surface of the reinforcing plate, and the insertion rod and the reinforcing plate are fixed by screws.

[0007] Preferably, one end of the connecting gear is fully fitted to the outer surface of the reinforcing plate, and the connecting gear and the reinforcing plate are fixed by welding.

[0008] Preferably, the outer side of the reinforcing plate is completely fitted with the inner surface of the rotating wheel, and the reinforcing plate and the rotating wheel are fixed by welding.

[0009] Preferably, one end of the spring is fully attached to the lower surface of the first positioning block, and the spring and the first positioning block are fixed by welding.

[0010] Preferably, the inner surface of one end of the rotating wheel is uniformly provided with limiting grooves, and the limiting grooves correspond to one end of the first positioning block.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a heat-conducting plate and a heat sink to be set on the outer side of one end of the connecting shaft. When the rotating wheel is working, it will drive the connecting shaft to rotate, which will generate a lot of heat. The heat-conducting plate and heat sink can effectively dissipate heat from the connecting shaft, reduce the impact of high temperature on the main body, and improve the heat dissipation effect of the device. 2. This utility model features a toothed groove at one end of the connecting shaft, a reinforcing plate on the inner side of the rotating wheel, a connecting gear, and a plug rod. The connecting gear connects with the toothed groove, increasing the reliability of the connection between the rotating wheel and the connecting shaft and improving the transmission effect of the rotating wheel. By setting a first positioning block, a spring, and a connecting groove at the connection between the rotating wheel and the connecting shaft, the positioning effect of the rotating wheel is enhanced by the spring and the first positioning block. Then, by using a pressing ring, rotating the pressing ring causes the pressing ring to press the first positioning block, which can separate the first positioning block from the rotating wheel, facilitating the disassembly and assembly of the rotating wheel. This makes it convenient for workers to replace and repair the rotating wheel, improving the ease of use of the device. Attached Figure Description
