Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 4The utility model provides a dynamometer for elevator inspection and detection, including an elevator dynamometer body 1; a pair of fixed blocks 11 are fixedly connected to the side walls of the elevator dynamometer body 1; the fixed blocks 11 are symmetrically arranged on both sides of the elevator dynamometer body 1 and have the same structure; a first anti-slip pad 12 is fixedly connected to the side walls of the fixed blocks 11; a screw 13 is rotatably connected to the side wall of the elevator dynamometer body 1; a bracket 14 is threadedly connected to the side wall of the screw 13; a pair of clamping blocks 15 are fixedly connected to the side wall of the bracket 14; the clamping blocks 15 are symmetrically arranged on both sides of the bracket 14 and have the same structure; a second anti-slip pad 16 is fixedly connected to the side wall of the clamping block 15; a pair of telescopic rods 17 are symmetrically fixed between the bracket 14 and the elevator dynamometer body 1; when in use, the rope is first hooked by the fixed block 11 so that it is placed on the fixed block 1 1 side wall, and then hold the screw rod 13 and rotate it. As the screw rod 13 rotates, under the limiting effect of the telescopic rod 17, the bracket 14 can be lifted and moved, so that the clamping block 15 is close to the fixed block 11, so as to clamp and fix the rope. At this time, the second anti-skid pad 16 and the first anti-skid pad 12 fit the rope, which can generate a certain friction force to reduce the sliding phenomenon of the elevator dynamometer body 1 on the rope. In this process, the rope is clamped by the fixed block 11 and the clamping block 15, which can play a role in fixing the elevator dynamometer body 1 on the rope, thereby improving the stability of the elevator dynamometer body 1 during detection. At the same time, the first anti-skid pad 12 and the second anti-skid pad 16 can play a role in preventing the elevator dynamometer body 1 from sliding when in use, thereby improving the accuracy of the elevator dynamometer body 1 during detection.

[0026] Further, such as Figure 1 , Figure 3 , Figure 4 As shown, the side wall of the elevator dynamometer body 1 is fixedly connected to a mounting block 2; the side wall of the mounting block 2 is provided with a slot 21; the side wall of the screw rod 13 is fixedly connected to a support arm 22; the side wall of the support arm 22 is fixedly connected to a spring 23; the end of the spring 23 is fixedly connected to a plug rod 24; the side wall of the plug rod 24 is fixedly connected to a pull plate 25; the pull plate 25 penetrates the wall of the support arm 22 and is slidably connected thereto; when in use, after the fixing block 11 and the clamping block 15 have completed clamping the rope, the plug rod 24 is made to correspond to the position of the mounting block 2, and at this time, the pull plate 25 is held and pulled to be pulled from the side wall of the screw rod 13 The pull plate 25 is then removed from the upper part and then rotated to move the pull plate 25 away from the screw rod 13. At this time, the pull plate 25 is released and the insertion rod 24 can be pushed by the elasticity of the spring 23 to be pushed into the side wall of the slot 21 to fix the screw rod 13. In this process, the insertion rod 24 is inserted into the side wall of the slot 21 to prevent the screw rod 13 from rotating after use, thereby improving the fixing effect of the screw rod 13 and reducing the risk that the elevator dynamometer body 1 will accidentally rotate to the screw 13 during use, which may cause the fixing block 11 and the clamping block 15 to loosen and cause the elevator dynamometer body 1 to fall off.

[0027] Further, such as Figure 4 As shown, the side wall of the insertion rod 24 is evenly provided with a plurality of card slots 3; the side wall of the slot 21 is fixedly connected with a plurality of elastic sheets 31; the elastic sheets 31 are evenly distributed on the side wall of the slot 21 and have the same structure; the side wall of the elastic sheet 31 is fixedly connected with a rubber block 32; when in use, during the process of inserting the insertion rod 24 into the side wall of the slot 21, the insertion rod 24 will squeeze the elastic sheet 31 to cause it to produce a certain deformation, and then when the insertion rod 24 is completely inserted into the side wall of the slot 21, the rubber block 32 can correspond to the position of the card slot 3, At this time, the elasticity of the elastic sheet 31 can make the rubber block 32 stuck into the side wall of the slot 3, and a certain friction force will be generated when the rubber block 32 and the slot 3 are fully fitted, so as to fix the insertion rod 24. In this process, the rubber block 32 is stuck into the side wall of the slot 3, which can prevent the insertion rod 24 from sliding on the side wall of the slot 21, improve the fixing effect of the insertion rod 24 on the side wall of the slot 21, and reduce the risk of the insertion rod 24 shaking on the side wall of the slot 21 when the insertion rod 24 is accidentally pulled due to the action of the spring 23.

[0028] Further, such as Figure 2 As shown, the side wall of the fixed block 11 is fixedly connected to a cleaning brush plate 4; the side wall of the cleaning brush plate 4 is fixedly connected to a connecting rod 41; when in use, by placing the rope on the side wall of the fixed block 11, the elevator dynamometer body 1 is slid up and down, and the surface of the rope can be cleaned by the cleaning brush plate 4 at this time, and the dust and impurities attached to the surface of the rope can be swept away so that it can fully fit with the first anti-slip pad 12, and at the same time, when the cleaning brush plate 4 is cleaning, the bristles on the side wall of the cleaning brush plate 4 can be fixedly connected by the connecting rod 41, so that they are concentrated together when cleaning. In this process, the surface of the rope is cleaned by the cleaning brush plate 4, which can clean the dust and impurities attached to the surface of the rope, improve the full fit between the rope and the first anti-slip pad 12, and at the same time, the concentration of the bristles on the side wall of the cleaning brush plate 4 can be improved by the connecting rod 41, thereby improving the cleaning effect.

[0029] Further, such as Figure 4 As shown, a groove 5 is provided on the side wall of the support arm 22; an elastic ball 51 is fixedly connected to the side wall of the pull plate 25; when in use, by placing the pull plate 25 on the side wall of the support arm 22, a certain pressure can be applied to the pull plate 25, and the elastic ball 51 will shrink due to being squeezed at this time, and when it is pressed into the side wall of the groove 5, it can quickly expand and recover under the elastic action of the elastic ball 51, so that it is stuck and the pull plate 25 is fixed. In this process, the elastic ball 51 is stuck into the side wall of the groove 5, which can fix the pull plate 25 on the side wall of the support arm 22, improve the anti-falling effect of the pull plate 25 when not in use, and reduce the pull plate 25 from slipping off the side wall of the support arm 22 when it is pulled during the rotation of the screw rod 13.

[0030] Further, such as Figure 1 , Figure 2 As shown, a pair of elastic plates 6 are symmetrically fixed to the side wall of the fixed block 11; the elastic plates 6 are arranged in an arc shape; when in use, the fixed block 11 is pressed against the side wall of the rope, and the rope can squeeze the elastic plate 6 open at this time. When the rope is placed on the side wall of the fixed block 11, the rope can be buckled by the elastic plate 6 to prevent the fixed block 11 from falling off from the side wall of the rope. In this process, the rope is buckled by the elastic plate 6, which can pre-fix the rope, improve the convenience of fixing the elevator dynamometer body 1, and reduce the risk of the fixed block 11 falling off from the side wall of the rope when the screw 13 is rotated, thereby increasing a certain amount of workload.

[0031] Further, such as Figure 3 As shown, the side wall of the screw rod 13 is evenly fixed with a plurality of rubber strips 7; during use, when the screw rod 13 is held and rotated, the rubber strips 7 will fully contact with the hand and generate a certain friction force. In this process, the rubber strips 7 can prevent the hand from falling off the side wall of the screw rod 13, improve the fixing effect during rotation, and reduce the risk of the hand slipping off the side wall of the screw rod 13 when the screw rod 13 is held and rotated.

[0032] Working principle: When in use, first hook the rope through the fixed block 11 and place it on the side wall of the fixed block 11, then hold the screw 13 and rotate it. As the screw 13 rotates, under the limiting effect of the telescopic rod 17, the bracket 14 can be lifted and moved, so that the clamping block 15 is close to the fixed block 11, thereby clamping and fixing the rope. At this time, the second anti-slip pad 16 and the first anti-slip pad 12 fit the rope to generate a certain friction force, reducing the sliding phenomenon of the elevator dynamometer body 1 on the rope. When in use, after the fixed block 11 and the clamping block 15 have completed the clamping of the rope, the position of the insertion rod 24 and the mounting block 2 is adjusted. Correspondingly, at this time, the pull plate 25 is held and pulled to be removed from the side wall of the screw rod 13, and then the pull plate 25 is rotated to make the pull plate 25 away from the screw rod 13. At this time, the pull plate 25 is released, and the elasticity of the spring 23 can push the insertion rod 24 to push it into the side wall of the slot 21 to fix the screw rod 13. When in use, during the process of inserting the insertion rod 24 into the side wall of the slot 21, the insertion rod 24 will squeeze the elastic sheet 31 to cause it to produce a certain deformation. After that, when the insertion rod 24 is fully inserted into the side wall of the slot 21, the rubber block 32 can correspond to the position of the card slot 3. At this time, the elasticity of the elastic sheet 31 can make the rubber The rubber block 32 is inserted into the side wall of the card slot 3, and a certain friction force is generated by the full fit between the rubber block 32 and the card slot 3, so that the insertion rod 24 is fixed. When in use, by placing the rope on the side wall of the fixing block 11, the elevator dynamometer body 1 is slid up and down. At this time, the cleaning brush plate 4 can be used to clean the surface of the rope, and the dust and impurities attached to the surface of the rope can be swept away, so that it can be fully fitted with the first anti-slip pad 12. At the same time, when the cleaning brush plate 4 is cleaning, the bristles on the side wall of the cleaning brush plate 4 can be fixedly connected by the connecting rod 41, so that they are concentrated together when cleaning. When in use, by pulling the plate After 25 is placed on the side wall of the support arm 22, a certain pressure can be applied to the pull plate 25. At this time, the elastic ball 51 will shrink due to the squeezing. When it is pressed into the side wall of the groove 5, it can quickly expand and recover under the elastic action of the elastic ball 51, so that it is stuck and the pull plate 25 is fixed. When in use, the fixing block 11 is pressed against the side wall of the rope. At this time, the rope can squeeze the elastic plate 6 open. When the rope is placed on the side wall of the fixing block 11, the rope can be buckled through the elastic plate 6 to prevent the fixing block 11 from falling off the side wall of the rope. When in use, when the grip screw 13 is rotated, the rubber strip 7 will fully contact with the hand and generate a certain friction.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
