Description

Technical Field

[0001] The utility model relates to the technical field of life testers, in particular to a compensation chain life tester. Background Art

[0002] The life tester is used to test the life of the elevator balance compensation chain. The life tester consists of a test box, a motor group, a winding wheel, a wire rope, a hook, and a fixing mechanism. When using the service life tester, one end of the elevator balance compensation chain is fixed to the fixing mechanism inside the test box, and then the other end is hung on the hook. The first motor is started and the motor is rotated forward and reversed continuously to rotate the winding wheel, so that the wire rope is wound around the winding wheel and the wire rope is loosened, thereby driving the elevator balance compensation chain to move. After multiple movements, the test is stopped, and then the worker removes the elevator balance compensation chain and observes the surface damage of the elevator balance compensation chain to test the life of the elevator balance compensation chain.

[0003] The inventor found in his daily work that when the life tester is in use, when the elevator balance compensation chain is removed, the fixing mechanism that fixes the elevator balance compensation chain is usually released, causing the elevator balance compensation chain to fall to the bottom of the inner wall of the test box due to its own weight. The elevator balance compensation chain falls and hits the bottom of the inner wall of the test box, which may cause wear on its surface, thereby affecting the accuracy of the test results. Utility Model Content

A compensation chain life tester is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a compensation chain life tester, comprising a test box, a first motor is installed on the inner wall of the test box, the output end of the first motor is fixedly connected to a winding wheel, the arc surface of the winding wheel is fixedly connected to a steel wire rope, the other end of the steel wire rope is fixedly connected to a hook, the inner wall of the test box is provided with an auxiliary component and a buffer component, the auxiliary component includes a slide rail opened on one side of the inner wall of the test box, the inner wall of the slide rail is slidably connected to a moving rod, one end of the moving rod is fixedly connected to a fixed cylinder, and the inner wall of the fixed cylinder is provided with a fixing mechanism.

[0006] The effect achieved by the above-mentioned components is: by setting up auxiliary components, when the elevator balance compensation chain needs to be lowered, the driving mechanism is used to slowly lower the moving rod in the slide rail, causing the fixed cylinder to lower. When the fixed cylinder drops to the bottom of the inner wall of the test box, the fixing mechanism is released, causing the elevator balance compensation chain to fall to the bottom of the inner wall of the test box, thereby reducing the force of the elevator balance compensation chain falling and hitting the test box, thereby avoiding the effect of the elevator balance compensation chain falling and hitting the test box to the greatest extent possible.

[0008] The effect achieved by the above components is: starting the second motor, cooperating with the encoder, causing the lead screw to rotate, causing the moving rod in the slide rail to slowly descend.

[0009] Preferably, the fixing mechanism comprises arc-shaped plates arranged on both sides of the inner wall of the fixing cylinder, and adjusting screws are threadedly inserted on both sides of the arc surface of the fixing cylinder, and the adjusting screws are rotatably connected to the arc-shaped plates.

[0010] The effect achieved by the above components is that a worker screws the adjusting screws on both sides to release the arc plates on both sides from fixing the elevator balance compensation chain.

[0011] Preferably, auxiliary rods are slidably inserted into both sides of the arc surface of the fixed cylinder, and the auxiliary rods are fixed to the arc plate.

[0012] The effect achieved by the above components is: by setting the auxiliary rod, the arc plate is limited.

[0013] Preferably, the buffer assembly includes a buffer platform arranged on the inner wall of the test box, and a buffer spring is fixedly connected to the lower end of the buffer platform.

[0014] The effect achieved by the above components is: when it is necessary to buffer the elevator balancing compensation chain from falling onto the inner wall of the test box, the elevator balancing compensation chain falls onto the buffer platform due to its own weight, and the buffer mechanism is used to buffer the elevator balancing compensation chain, thereby buffering the fall of the elevator balancing compensation chain as much as possible.

[0015] Preferably, the other end of the buffer spring is fixed to the test box, and the lower end of the buffer platform is fixedly connected to a damping rod.

[0016] The effect achieved by the above components is: by arranging the buffer spring and the damping rod, the elevator balance compensation chain is buffered.

[0017] Preferably, the buffer spring is sleeved on the arc surface of the damping rod, and a rubber pad is fixedly connected to the top of the buffer platform.

[0018] The effect achieved by the above components is: by arranging the rubber pad, the elevator balance compensation chain is provided with auxiliary buffering.

[0019] In summary, the beneficial effects of the present invention are as follows:

[0020] In the present utility model, an auxiliary component is provided, and when the elevator balancing compensation chain needs to be lowered, the moving rod in the slide rail is slowly lowered through the driving mechanism, so that the fixed cylinder is lowered. When the fixed cylinder drops to the bottom of the inner wall of the test box, the fixing mechanism is released, so that the elevator balancing compensation chain falls to the bottom of the inner wall of the test box, thereby reducing the force of the elevator balancing compensation chain falling and hitting the test box, and thus avoiding the effect of the elevator balancing compensation chain falling and hitting the test box to the greatest extent possible to affect the results. This solves the problem that when the elevator balancing compensation chain is removed, the fixing mechanism for fixing the elevator balancing compensation chain is usually released, so that the elevator balancing compensation chain falls to the bottom of the inner wall of the test box due to its own weight, and the elevator balancing compensation chain falling and hitting the bottom of the inner wall of the test box may cause wear on its surface, which may affect the accuracy of the test results.

[0027] Reference Figure 1 and Figure 2 as well as Figure 5As shown, the utility model provides a technical solution: the compensation chain life tester includes a test box 1, a first motor 4 is installed on the inner wall of the test box 1, the output end of the first motor 4 is fixedly connected to a winding wheel 6, the arc surface of the winding wheel 6 is fixedly connected to a wire rope 7, the other end of the wire rope 7 is fixedly connected to a hook 8, and the inner wall of the test box 1 is provided with an auxiliary component 2 and a buffer component 3.

[0028] The following describes in detail the specific configuration and functions of the auxiliary component 2 and the buffer component 3.

[0029] Reference Figure 3 As shown, in this embodiment: the auxiliary component 2 includes a slide rail 21 opened on one side of the inner wall of the test box 1, the inner wall of the slide rail 21 is slidably connected with a moving rod 23, one end of the moving rod 23 is fixedly connected with a fixed cylinder 24, and the inner wall of the fixed cylinder 24 is provided with a fixing mechanism 25. By setting the auxiliary component 2, when it is necessary to lower the elevator balance compensation chain, the driving mechanism is used to slowly lower the moving rod 23 in the slide rail 21, so that the fixed cylinder 24 is lowered. When the fixed cylinder 24 drops to the bottom of the inner wall of the test box 1, the fixing mechanism 25 is released, so that the elevator balance compensation chain falls to the bottom of the inner wall of the test box 1, thereby reducing the force of the elevator balance compensation chain falling and hitting the test box 1, thereby achieving the effect of avoiding the impact of the elevator balance compensation chain falling and hitting the test box 1 as much as possible. A second motor 5 is installed on the top of the test box 1. The inner wall of the slide rail 21 is rotatably connected with the screw rod 22, and the output end of the second motor 5 passes through the test box 1 and is fixed to the screw rod 22. The screw rod 22 is threadedly connected to the moving rod 23. Start the second motor 5 and cooperate with the encoder to rotate the screw rod 22, so that the moving rod 23 in the slide rail 21 slowly descends. The fixing mechanism 25 includes an arc plate 251 arranged on both sides of the inner wall of the fixed cylinder 24, and adjusting screws 252 are threadedly inserted on both sides of the arc surface of the fixed cylinder 24. The adjusting screw 252 and the arc plate 251 are rotatably connected. The worker twists the adjusting screws 252 on both sides to release the arc plates 251 on both sides from fixing the elevator balance compensation chain. Auxiliary rods 253 are slidably inserted on both sides of the arc surface of the fixed cylinder 24. The auxiliary rod 253 and the arc plate 251 are fixed. The arc plate 251 is limited by setting the auxiliary rod 253.

[0030] Reference Figure 4As shown, in this embodiment: the buffer assembly 3 includes a buffer platform 31 arranged on the inner wall of the test box 1, and the lower end of the buffer platform 31 is fixedly connected to a buffer spring 32. When it is necessary to buffer the elevator balance compensation chain from falling to the inner wall of the test box 1, the elevator balance compensation chain falls to the buffer platform 31 due to its own weight, and the buffer mechanism is used to buffer the elevator balance compensation chain, thereby buffering the fall of the elevator balance compensation chain as much as possible. The other end of the buffer spring 32 is fixed to the test box 1, and the lower end of the buffer platform 31 is fixedly connected to a damping rod 33. By arranging the buffer spring 32 and the damping rod 33, the elevator balance compensation chain is buffered. The buffer spring 32 is sleeved on the arc surface of the damping rod 33, and the top of the buffer platform 31 is fixedly connected to a rubber pad 34. By arranging the rubber pad 34, the elevator balance compensation chain is assisted in buffering.

[0031] Working principle:

[0032] When using the service life tester, fix one end of the elevator balance compensation chain to the fixing mechanism 25 inside the test box 1, and then hang the other end on the hook 8, start the first motor 4, and let the motor rotate forward and reverse continuously to make the winding wheel 6 rotate, so that the wire rope 7 is wound around the winding wheel 6 and the wire rope 7 is loosened, thereby driving the elevator balance compensation chain to move. After multiple movements, stop the test, and then the worker removes the elevator balance compensation chain and observes the surface damage of the elevator balance compensation chain to test the life of the elevator balance compensation chain. When it is necessary to lower the elevator balance compensation chain, start the second motor 5 and cooperate with the encoder to rotate the screw rod 22, so that the moving rod 23 in the slide rail 21 slowly descends, causing the fixed cylinder 24 to descend. When the fixed cylinder 24 descends to the bottom of the inner wall of the test box 1, the worker turns the adjusting screws on both sides. Rod 252 releases the fixation of the elevator balance compensation chain by the arc plates 251 on both sides, so that the elevator balance compensation chain falls to the bottom of the inner wall of the test box 1, thereby reducing the force of the elevator balance compensation chain falling and hitting the test box 1, and thus avoiding the effect of the elevator balance compensation chain falling and hitting the test box 1 to the greatest extent possible. The arc plate 251 is limited by setting an auxiliary rod 253. When it is necessary to buffer the elevator balance compensation chain from falling to the inner wall of the test box 1, after the elevator balance compensation chain falls to the buffer platform 31 due to its own weight, the buffer spring 32 and the damping rod 33 are set to buffer the elevator balance compensation chain, so that the elevator balance compensation chain is buffered, and thus the falling of the elevator balance compensation chain is buffered as much as possible. The elevator balance compensation chain is auxiliary buffered by setting a rubber pad 34.
