Hereinafter, an embodiment of the present utility model will be described in terms of its overall structure.
Referring to fig. 1, an embodiment of the present application provides a speed limiter testing apparatus, including:
A first winding drum 1 and a second winding drum 2 which are arranged close to each other;
A first wheel 3 and a second wheel 4 arranged near the same side of the first reel 1 and the second reel 2;
The speed limiter 51 is arranged between the first winding drum 1 and the second winding drum 2 and the first wheel 3 and the second wheel 4, the speed limiter 51 is arranged in the fixed frame 5, and the fixed frame 5 is arranged on the side wall of the direct sliding rail 6;
the rope 8 is wound on the outer walls of the first winding drum 1 and the second winding drum 2, and the rope 8 is also wound on the outer walls of the first wheel 3, the second wheel 4 and the speed limiter 51;
The driving part 9 is arranged between the first winding drum 1 and the speed limiter 51, the driving part 9 is connected with the first winding drum 1 or the second winding drum 2 through a belt, the first winding drum 1 is connected with the second winding drum 2 through a synchronous belt 7 and is used for driving the first winding drum 1 and the second winding drum 2 to synchronously rotate, and the rope 8 is wound and driven.
According to fig. 1 and 2, a person skilled in the art sets a first reel 1 and a second reel 2. The first spool 1 is disposed adjacent to the second spool 2. A first wheel 3 and a second wheel 4 are also arranged at the same side of the first winding drum 1 and the second winding drum 2. In actual operation, the first wheel 3 and the second wheel 4 may be disposed above the first reel 1 and the second reel 2.
Further, the person skilled in the art installs the speed limiter 51 between the first reel 1 or the second reel 2 and the first wheel 3 or the second wheel 4. In the mounting of the speed limiter 51, the speed limiter 51 is mounted in the fixed frame 5, and the fixed frame 5 is mounted on the side wall of the direct slide rail 6. I.e. the speed limiter 5 is mounted on the opposite wall of the direct track 6.
The person skilled in the art can connect the first reel 1, the second reel 2, the first wheel 3, the second wheel 4 and the speed limiter 51 by arranging the rope 8. Specifically, the rope 8 is wound around the outer walls of the first drum 1, the second drum 2, the first wheel 3, the second wheel 4, and the speed limiter 51.
In the above-described configuration, the first drum 1 and the second drum 2 wind the rope 8, and the rope 8 can be moved. When the rope 8 moves, the speed limiter 51 provided on the rope 8 can be operated. During this process, the person skilled in the art can check the service life of the speed limiter 51.
In the above specific process of detection, the worker may make the first spool 1 and the second spool 2 rotate clockwise or counterclockwise in synchronization, and may further perform specific life detection on the speed limiter 51.
According to the above specific detection process, in order to make the first reel 1 and the second reel 2 rotate synchronously in the same direction, the first reel 1 and the second reel 2 may be connected by the timing belt 7. Further, a driving unit 9 is provided between the first spool 1 or the second spool 2 and the speed limiter 51. The driving unit 9 is connected to the first reel 1 or the second reel 2, and thus the power for rotating the first reel 1 and the second reel 2 can be applied.
Preferably, the driving part 9 drives the first reel 1 and the second reel 2 to rotate clockwise and counterclockwise. In order to meet the requirement of detecting the speed limiter when the expansion and contraction move in two opposite directions in the detection process, a person skilled in the art can drive the first winding drum 1 and the second winding drum 2 to rotate clockwise and anticlockwise by arranging the driving part 9. When the driving unit 9 rotates the first drum 1 and the second drum 2 clockwise and counterclockwise, the first drum 1 and the second drum 2 move the rope 8 in two opposite directions. Further, the lifetime of the speed limiter 51 can be detected.
Preferably, the driving part 9 is provided as a motor. That is, a rotational force is applied to the first roll 1 or the second roll 2 by a motor. When the first winding drum 1 or the second winding drum 2 rotates, the first winding drum 1 and the second winding drum 2 can synchronously rotate through synchronous transmission of the synchronous belt 7. Synchronous rotation of the first spool 1 and the second spool 2 may cause the rope 8 to move, thereby detecting the service life of the speed limiter 51. The output end of the motor can perform forward rotation and reverse rotation. And thus the first roll 1 and the second roll 2 can be rotated clockwise and counterclockwise.
According to fig. 1 and 2, in order to maintain the tension of the rope 8 itself when it rotates, it is preferable that a weight 52 is also fixedly provided on the fixing frame 5. In testing the service life of the speed limiter 51, a person skilled in the art can adjust the tension of the rope 8 by setting the weight 52 in order to meet the requirements for different tensions of the rope 8.
As can be seen from fig. 2, the weight 52 is provided on the fixed frame 5, the fixed frame 5 can move up and down, and when the length of the rope 8 is changed, the fixed frame 5 is pulled down by the weight tension to ensure the tension.
In the arrangement of the first roll 1 and the second roll 2, the first roll 1 is preferably arranged in parallel with the second roll 2. The foregoing structure makes it possible to keep the state of movement of the rope 8 stable when the first reel 1 and the second reel 2 are rotated. That is, the parallel first drum 1 and second drum 2 can prevent the rope 8 from slipping due to jumping during movement.
Preferably, the first winding drum 1 and the second winding drum 2 are provided with accommodating grooves, and the number and the groove type of the accommodating grooves are matched with those of the ropes. During the winding of the rope 8 by the first and second drums 1, 2, the rope 8 is wound into the receiving grooves provided in the first and second drums 1, 2. Specifically, the arrangement of the accommodation groove is set according to the size and type of the rope 8. The provision of the receiving channel further avoids the rope 8 from jumping out during winding. So that the detection process of the service life of the speed limiter 51 is more stable and the detection data is more accurate.
In the arrangement of the first wheel 3 and the second wheel 4, the first wheel 3 and the second wheel 4 are preferably arranged independently. The first wheel 3 and the second wheel 4 are provided independently. The rope 8 can be moved more conveniently, and further the condition that the rope 8 is blocked in the moving process is avoided. Further making the detected data more accurate. In one embodiment, preferably, both the first wheel 3 and the second wheel 4 are provided as tensioning wheels or reversing wheels. Thereby enabling the detection device to be applied to various detection scenes.
In the above arrangement, when the speed limiter 51 is detected, the speed limiter 51 sample is prevented from being mounted on the elevator for testing, and the testing cost is reduced. Furthermore, the test equipment is installed on the general ground, so that the detection personnel can directly observe and record the test equipment in real time conveniently, and meanwhile, the test equipment does not need to ascend a height and enter a parallel passage, so that the safety is improved. And the number of parts of the detection equipment is small, so that the reliability of the test data is improved.
