Description

Technical Field

[0001] The utility model belongs to the technical field of wire rope tension testing equipment, and particularly relates to an elevator wire rope tension tester. Background Art

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. Conventionally, regardless of its driving method, the elevator is generally referred to as the vertical transportation tool in the building.

[0003] When the operator is overhauling the elevator, the tension of the elevator wire rope is often tested, so as to accurately understand the wear condition of the wire rope and ensure the safe operation of the elevator. The existing elevator wire ropes are often detected by a tension tester. When the existing tension tester is in use, the operator often needs to first fit the wire rope with two auxiliary wheels, and then turn the screw rod to make the pressing wheel move forward to press the wire rope. However, when the operator turns the screw rod, the tester as a whole often deflects, which will cause the wire rope to move outside the two auxiliary wheels, resulting in the operator having to turn the screw rod while repeatedly adjusting the positions of the auxiliary wheels and the wire rope to ensure that the two auxiliary wheels can always fit with the wire rope. This brings inconvenience to the operator's detection operation and reduces the detection efficiency. Therefore, it needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an elevator wire rope tension tester to solve the problems raised in the above background art.

[0019] (1) The utility model provides a toothed plate, a first spring, a second spring and a moving wheel. When the round rod drives the moving block to move backward, the first spring will be compressed, and the toothed plate and the long rod will move backward under the drive of the moving block. Then the long rod will drive the vertical rod and the moving wheel to move backward through the moving plate. At this time, the wire rope will be clamped by the moving wheel and the auxiliary wheel. At the same time, the toothed plate will repeatedly squeeze the block during the backward movement, so that the block moves to the left along the inside of the short groove. When the toothed plate stops moving, the block will reset to the right under the elastic force of the second spring. At this time, the overall movement of the toothed plate will be locked, so that the wire rope and the auxiliary wheel can be quickly fitted.

[0020] (2) The utility model sets a shift lever, a lifting plate, a third spring and a second spring. When the two shift levers are in contact with the round block, the two shift levers will block the overall movement of the round block. When the lifting plate moves upward along the outer surface of the limit rod, the third spring will be stretched. At the same time, the lifting plate will drive the two shift levers to move upward at the same time. Then, the two shift levers will release the blocking effect on the overall round block during the upward movement, so that the operator can replace the screw rod conveniently and quickly.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1:

[0029] Please refer to Figures 1 - 5 As shown, an elevator wire rope tension tester includes:

[0030] The tester body 1, and auxiliary wheels 3 are movably installed inside both the left and right sides of the tester body 1;

[0031] The locking mechanism is arranged at the bottom end of the tester body 1;

[0032] The clamping mechanism is arranged inside the rear of the bottom end of the tester body 1;

[0033] Among them, the clamping mechanism includes a round rod 5. The outer surface of the rear end of the round rod 5 is movably sleeved inside the rear of the bottom end of the tester body 1. The front end of the round rod 5 is fixedly sleeved with a moving block 6. The outer surface of the moving block 6 is fixedly installed with a first spring 7. The inside of the first spring 7 is movably sleeved with the outer surface of the round rod 5. The rear end of the first spring 7 is fixedly connected to the outer surface of the bottom end of the tester body 1. A toothed plate 8 is fixedly installed on the left side of the moving block 6. A long rod 9 is fixedly installed on the rear end of the moving block 6. The top end of the long rod 9 is movably connected to the bottom end of the tester body 1. The left and right sides of the front of the long rod 9 are fixedly installed with moving plates 10. The inside of the front end of the moving plate 10 is fixedly sleeved with a vertical rod 11. A moving wheel 12 is movably sleeved on the outer surface of the vertical rod 11.

[0034] When the round rod 5 moves backward along the inside of the rear of the bottom end of the tester body 1, at this time the moving block 6 will move backward under the drive of the round rod 5. During this process, the first spring 7 will be in a compressed state. Due to the elastic force of the first spring 7, it will play a good reset role in the overall movement of the moving block 6. At the same time, the moving block 6 will drive the toothed plate 8 and the long rod 9 to move backward. Then the long rod 9 will drive the two moving plates 10 to move backward at the same time. At this time, the two moving plates 10 will drive the two moving wheels 12 to move backward through the two vertical rods 11. At this time, the two moving wheels 12 will cooperate with the two auxiliary wheels 3 during the backward movement to clamp and fix the wire rope.

[0035] From Figure 1 and Figure 4It can be seen that the locking mechanism includes a fixing block 13, the left side of the top of the fixing block 13 is fixedly connected to the bottom of the tester body 1, and a short slot 14 is provided at the top of the fixing block 13;

[0036] A stopper 15 is movably connected inside the short slot 14 , a second spring 16 is fixedly installed on the left side of the stopper 15 , the left side of the second spring 16 is fixedly connected to the inside of the short slot 14 , and the right side of the stopper 15 is movably connected to the outer surface of the toothed plate 8 .

[0037] When the tooth plate 8 moves backward, it will squeeze and push the block 15. At this time, the block 15 will move to the left under the limit of the short slot 14. In this process, the second spring 16 will be compressed. Due to the elastic force of the second spring 16, the movement of the block 15 will be well reset. Due to the design of the tooth plate 8 and the block 15, the tooth plate 8 can only move backward, thereby blocking the overall movement of the tooth plate 8 and thus playing a locking role.

[0038] Specifically, regarding the above, refer to Figure, Figure 2 and Figure 4 As shown, the outer surface of the moving plate 10 is movably connected to a support block 18 , and the outer surface of the support block 18 is fixedly connected to the outer surface of the tester body 1 .

[0039] Due to the design of the two supporting blocks 18 , the two sport boards 10 can be well supported.

[0040] For details about the above, refer to Figure 1 and Figure 3 As shown, a tension sensor 19 is fixedly mounted on the front of the tester body 1 , a fixing plate 20 is fixedly mounted on the bottom of the tension sensor 19 , a screw rod 21 is sleeved on the internal thread of the front of the fixing plate 20 , and a rocker arm 22 is fixedly mounted on the front end of the screw rod 21 .

[0041] Since the fixing plate 20 and the screw rod 21 are threadedly sleeved, when the rocker 22 drives the screw rod 21 to rotate, the screw rod 21 will move back and forth along the inside of the fixing plate 20 .

[0042] For details about the above, refer to Figure 5 As shown, a round block 23 is fixedly mounted at the rear end of the screw rod 21 , a movable block 24 is movably sleeved on the outer surface of the round block 23 , and an extrusion wheel 25 is movably sleeved inside the rear end of the movable block 24 .

[0043] When the screw 21 moves backward, the round block 23 will move backward driven by the screw 21, and then the round block 23 will drive the movable block 24 and the extrusion wheel 25 to move backward. At this time, the extrusion wheel 25 will cooperate with the tension sensor 19 to squeeze the wire rope during the backward movement, thereby being able to perform tension testing on the wire rope.

[0044] As can be seen from the above, first the operator places the wire rope between the two auxiliary wheels 3 and the two moving wheels 12, and then the operator pushes the round rod 5. At this time, the round rod 5 will drive the moving block 6 to move backward. At this time, the first spring 7 will be in a compressed state. At the same time, the moving block 6 will simultaneously drive the toothed plate 8 and the long rod 9 to move backward. Then the long rod 9 will drive the two vertical rods 11 and the two moving wheels 12 to move backward through the two moving plates 10. Then the two moving wheels 12 will cooperate with the two auxiliary wheels 3 to clamp the wire rope during the backward movement. In this process, the outer surface of the toothed plate 8 will repeatedly squeeze and push the block 15. Due to the limitation of the short slot 14, the block 15 will move along the short slot 14. The inside of the groove 14 moves to the left, and the second spring 16 will be in a compressed state. Due to the elastic force of the second spring 16, when the tooth plate 8 stops moving backward, the second spring 16 will drive the stopper 15 to move to the right for reset. Due to the design of the shape of the stopper 15, the stopper 15 will block the forward movement of the tooth plate 8, thereby locking the movement of the tooth plate 8, thereby realizing the function of quickly fitting the wire rope to the auxiliary wheel 3. When the operator moves the stopper 15 to move to the left, the stopper 15 will release the locking effect on the tooth plate 8. At this time, the tooth plate 8 as a whole will move forward under the elastic force of the first spring 7 for reset, thereby releasing the clamping of the wire rope.

[0045] Then the operator shakes the rocker 22, and the rocker 22 will drive the screw 21 to rotate. Since the outer surface of the screw 21 is sleeved with the internal thread of the fixed plate 20, the screw 21 will move backward while rotating. At the same time, the screw 21 will drive the movable block 24 to move backward as a whole through the round block 23. At this time, the extrusion wheel 25 will cooperate with the tension sensor 19 to squeeze the wire rope during the backward movement, so that the tension of the wire rope can be tested.

[0046] Embodiment 2:

[0047] refer to Figure 1 , Figure 3 and Figure 5 As shown, a limit rod 26 is fixedly installed on the top of the movable block 24, and a lifting plate 4 is movably sleeved on the outer surface of the limit rod 26. A third spring 17 is fixedly installed on the bottom end of the lifting plate 4, and the bottom end of the third spring 17 is fixedly connected to the top of the movable block 24.

[0048] Due to the design of the limit rod 26, the lifting plate 4 can only move up and down along the limit rod 26. When the lifting plate 4 moves upward, the third spring 17 will be in a stretched state. Due to the design of the third spring 17, the movement of the lifting plate 4 will have a good resetting effect.

[0049] Preferably, blocking rods 2 are fixedly installed on both the left and right sides of the bottom end of the lifting plate 4. The outer surface of the blocking rod 2 is movably sleeved inside the movable block 24, and the back surface of the blocking rod 2 is movably connected to the front surface of the round block 23.

[0050] When the lifting plate 4 moves upward, at this time, the two blocking rods 2 will move upward along the inside of the movable block 24 under the drive of the lifting plate 4. Subsequently, the two blocking rods 2 will disengage from the contact with the round block 23 during the upward movement. At this time, the two blocking rods 2 will not be able to block the movement of the round block 23, so that it is convenient to replace the whole round block 23.

[0051] As can be seen from the above, when the screw rod 21 is worn, at this time, the operator pulls the lifting plate 4. Due to the design of the limiting rod 26, the movement of the lifting plate 4 will be limited, and it can only move up and down. At this time, the lifting plate 4 will drive the two blocking rods 2 to move upward. At the same time, the third spring 17 will be in a stretched state. Due to the elastic force of the third spring 17, it will have a good reset effect on the overall movement of the lifting plate 4. When the two blocking rods 2 disengage from the contact with the round block 23 during the upward movement, at this time, the blocking rods 2 will not be able to block the movement of the whole round block 23, so that the operator can conveniently and quickly replace the screw rod 21.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
