Description

Technical Field

[0001] This utility model belongs to the field of clamp testing technology, specifically relating to a clamp bearing capacity testing device. Background Technology

[0002] The clamp bearing capacity testing device is mainly used to measure the bearing capacity of clamps or ring clamps under external forces. By simulating actual working conditions, it tests whether they meet the design requirements. The test data can be used to evaluate material strength, structural stability and product quality, thereby avoiding safety hazards caused by insufficient bearing capacity.

[0003] To prevent material from splashing and causing safety hazards during testing, some existing clamp bearing capacity testing devices typically install protective net baskets on the outer edge of the work area to cover the work area. This method usually requires personnel to manually open and close the net baskets to place and remove clamps. When there are many clamps to be tested, the frequent manual opening and closing of the net baskets greatly increases the cumbersomeness of the operation, increases the physical exertion of the workers, and also has a relatively negative impact on the testing efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a clamp bearing capacity testing device. This addresses the issue mentioned in the background art where existing clamp bearing capacity testing devices typically install protective net baskets at the outer edge of the work area to shield the work area from material splashing after compression during the testing process. However, this method generally requires manual opening and closing of the net baskets to place and remove clamps. When there are many clamps to be tested, the frequent manual opening and closing of the net baskets greatly increases the cumbersomeness of the operation, increases the physical exertion of the workers, and also has a negative impact on the testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamp bearing capacity testing device, comprising a main body mechanism and a barrier mechanism disposed on the top of the main body mechanism, which can cover or open the work area without manual intervention by operators. The barrier mechanism includes a sleeve column slidably connected to the outside of the output end of a hydraulic telescopic cylinder. Several side frames are symmetrically arranged on the top of the outside of the sleeve column. A push-in screw is slidably connected to the inside of the side frame. A pressure ring is connected to the outside of one end of the push-in screw. A limit ring is fixedly connected to the outside of the other end of the push-in screw. A spring is arranged between the side frame and the limit ring. The push-in screw is movably connected to the inside of the spring. A ball is rotatably connected to the inside of the other end of the push-in screw. Several adapter arms are symmetrically arranged at the bottom of the outside of the sleeve column. A hollow column is fixedly connected to one side of the adapter arm. A column is slidably connected to the inside of the hollow column. An outer frame is fixedly connected between adjacent hollow columns. A protective net is fixedly connected to the inside of the outer frame.

[0006] Preferably, the main body mechanism includes a base plate, a base fixedly connected to one side of the top of the base plate, a plurality of columns symmetrically arranged on the other side of the top of the base plate, a top plate fixedly connected to the top of the columns, a hydraulic telescopic cylinder fixedly connected to the top of the top plate, a pressure plate fixedly connected to the bottom of the output end of the hydraulic telescopic cylinder, a slide rod fixedly connected to the top of the pressure plate, a plurality of slide rods symmetrically arranged, and a top plate slidably connected to the outer side of the slide rod.

[0008] Preferably, a buffer pad is fixedly connected to one side of the sleeve post, and two buffer pads are symmetrically arranged. The buffer pads are made of flexible material.

[0009] Preferably, the side frames are fixedly connected with reinforcing ribs between adjacent frames, and a sleeve column is fixedly connected to one side of the side frame.

[0010] Preferably, a gasket is movably connected to the outer side of the push screw, and the gasket is located between the side frame and the pressure ring.

[0012] Preferably, a limiting piece is fixedly connected to one end of the advancing screw.

[0013] Compared with the prior art, this utility model provides a device for testing the bearing capacity of a clamp, which has the following advantages:

[0014] 1. This utility model uses a sleeve column and a hydraulic telescopic cylinder to move the output end back. During the upward movement, multiple sets of balls clamp the output end of the hydraulic telescopic cylinder from various directions, creating friction between them. This causes the sleeve column to move upward synchronously with the output end of the hydraulic telescopic cylinder until the buffer pad at the top of the sleeve column contacts the bottom of the top plate. The sleeve column then stops moving upward due to the restriction at the top. Simultaneously, the rolling of the balls does not affect the hydraulic telescopic cylinder's output end from driving the pressure plate to rise until the top of the pressure plate contacts the buffer pad at the bottom of the sleeve column. At this point, the device is set to its initial position, and the base is fully exposed to the external environment. After placing the pressure clamp to be tested flat on the top of the base, the hydraulic telescopic cylinder is opened, causing the pressure plate to move downward. During this process, the sleeve column moves downward synchronously due to the friction caused by the balls clamping the output end of the hydraulic telescopic cylinder. When the sleeve column is in the vertical direction... After the sleeve column slides down to the bottom of the cavity column and the outer frame, which then contacts the top of the base plate, the bottom position of the enclosure mechanism is restricted, and the sleeve column stops moving down. Due to the rolling effect of the balls on the outer wall of the hydraulic telescopic cylinder output end, the downward pressure capacity of the hydraulic telescopic cylinder output end is not restricted. At this time, the shielding area composed of the outer frame and the protective net fully encloses the external area of ​​the base. Finally, the hydraulic telescopic cylinder continues to open, driving the output end of the hydraulic telescopic cylinder to move down between the balls, driving the pressure plate to apply pressure to the clamp and test its load-bearing capacity. When the pressure plate is moved back after the test is completed, the sleeve column is simultaneously reset, exposing the clamp after the test to the external environment for personnel to collect directly. This effectively avoids the need for personnel to frequently open and close the external shield. In the process of batch testing clamps, it not only simplifies the personnel's work process and reduces power input, but also ensures testing efficiency.

[0015] 2. This utility model, by setting a knob, can effectively and conveniently allow personnel to directly pinch and rotate the pressure ring to adjust the position of the screw and set the force of the ball contacting the outer wall of the hydraulic telescopic cylinder output end;

[0016] 3. By setting a limiting piece, this utility model can effectively reduce the risk of the pressure ring falling off due to excessive movement.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5This utility model provides a technical solution: a clamp bearing capacity testing device, including a main body mechanism 1 and a barrier mechanism 2 disposed on the top of the main body mechanism 1, which can cover or open the working area without manual intervention by the operator. The barrier mechanism 2 includes a sleeve column 201 slidably connected to the outside of the output end of a hydraulic telescopic cylinder 105. Several side frames 202 are symmetrically arranged on the top of the outside of the sleeve column 201. A push-in screw 203 is slidably connected to the inside of the side frame 202. A pressure ring 204 is connected to the outside of one end of the push-in screw 203. A limit ring 205 is fixedly connected to the outside of the other end of the push-in screw 203. A spring 206 is disposed between the side frame 202 and the limit ring 205. The push-in screw 203 is movably connected to the inside of the spring 206. A ball bearing 207 is rotatably connected to the inner side of the other end of the screw 203. Several adapter arms 208 are symmetrically arranged at the bottom of the outer side of the sleeve 201. A hollow column 209 is fixedly connected to one side of the adapter arm 208. A column 103 is slidably connected to the inner side of the hollow column 209. An outer frame 210 is fixedly connected between adjacent hollow columns 209. A protective net 211 is fixedly connected to the inner side of the outer frame 210. The output end is moved back by the hydraulic telescopic cylinder 105. During the upward movement, due to the multiple sets of ball bearings 207 clamping the output end of the hydraulic telescopic cylinder 105 from all directions, a certain frictional force is generated between the two, thereby driving the sleeve 201 to move upward synchronously with the output end of the hydraulic telescopic cylinder 105 until the buffer pad 3 at the top of the sleeve 201 contacts the bottom of the top plate 104. Due to the top restriction, 201 stops moving upwards. Simultaneously, due to the rolling of the ball bearings 207, the output end of the hydraulic telescopic cylinder 105 is not affected, causing the pressure plate 106 to rise until its top contacts the buffer pad 3 at the bottom of the sleeve column 201. At this point, the device is set to its initial position, and the base 102 is fully exposed to the external environment. After placing the pressure clamp to be tested flat on top of the base 102, the hydraulic telescopic cylinder 105 is opened, causing the pressure plate 106 to move downwards. During this process, the sleeve column 201 moves downwards synchronously due to the ball bearings 207 clamping the output end of the hydraulic telescopic cylinder 105 and providing a certain amount of friction. When the sleeve column 201 slides down vertically until the bottom of the cavity column 209 and the outer frame 210 contact the top of the base plate 101, the bottom position of the enclosure mechanism 2 is restricted. The sleeve 201 then stops moving downwards, and due to the rolling effect of the balls 207 on the outer wall of the output end of the hydraulic telescopic cylinder 105, the downward pressure capacity of the output end of the hydraulic telescopic cylinder 105 is not limited. At this time, the shielding area composed of the outer frame 210 and the protective net 211 fully encloses the external area of ​​the base 102. Finally, the hydraulic telescopic cylinder 105 continues to open, causing the output end of the hydraulic telescopic cylinder 105 to move downwards between the balls 207, driving the pressure plate 106 to apply pressure to the clamp, testing its load-bearing capacity. When the pressure plate 106 is moved back after the test, the sleeve 201 is simultaneously reset, exposing the clamp to the external environment for direct collection by personnel. This effectively avoids the need for frequent opening and closing of the external shield. During the batch testing of clamps,This not only simplified the work process for personnel and reduced energy input, but also ensured testing efficiency.

[0027] In this utility model, preferably, the main body mechanism 1 includes a base plate 101, a base 102 is fixedly connected to one side of the top of the base plate 101, and a plurality of columns 103 are symmetrically arranged on the other side of the top of the base plate 101. A top plate 104 is fixedly connected to the top of the columns 103, and a hydraulic telescopic cylinder 105 is fixedly connected to the top of the top plate 104. A pressure plate 106 is fixedly connected to the bottom of the output end of the hydraulic telescopic cylinder 105, and a sliding rod 107 is fixedly connected to the top of the pressure plate 106. A plurality of sliding rods 107 are symmetrically arranged, and the top plate 104 is slidably connected to the outer side of the sliding rod 107. The pressure clamp to be tested is placed on the top of the base 102, and then the hydraulic telescopic cylinder 105 is opened to drive the pressure plate 106 to press down, and the load-bearing capacity of the pressure clamp is tested. After the test is completed, the pressure plate 106 is moved back to reset, and the pressure clamp after the test is collected for evaluation.

[0028] In this utility model, preferably, both the ball bearing 207 and the protective net 211 are made of stainless steel. The ball bearing 207 is rotatably connected to the outside of the ball bearing 207, and the protective net 211 is fixedly connected to the outside of the frame 210. This provides better corrosion resistance and strength, and reduces the risk of material strength reduction due to oxidation and rust.

[0029] In this utility model, preferably, a buffer pad 3 is fixedly connected to one side of the sleeve post 201. Two buffer pads 3 are symmetrically arranged. The buffer pads 3 are made of flexible material, which can effectively reduce the wear of the sleeve post 201 on both sides when in direct contact.

[0030] In this utility model, preferably, the side frames 202 are fixedly connected with reinforcing ribs 4 between adjacent side frames 202, and a sleeve column 201 is fixedly connected to one side of the side frame 202, which can effectively improve the stability of the direct structure of the side frame 202.

[0031] In this utility model, preferably, a gasket 5 is movably connected to the outside of the push screw 203. The gasket 5 is located between the side frame 202 and the pressure ring 204, which can effectively reduce the loosening of the pressure ring 204 during long-term use and ensure the stability of the pressure ring 204.

[0032] In this utility model, preferably, a knob 6 is fixedly connected to one side of the pressure ring 204, and several knobs 6 are symmetrically arranged. The inner side of the pressure ring 204 is threaded with an abutting screw 203, which can effectively and conveniently allow personnel to directly squeeze and rotate the pressure ring 204 to adjust the position of the abutting screw 203 and set the force of the ball 207 contacting the outer wall of the output end of the hydraulic telescopic cylinder 105.

[0033] In this invention, preferably, a limiting piece 7 is fixedly connected to one end of the advancing screw 203, which can effectively reduce the risk of the pressure ring 204 falling off due to excessive movement.

[0034] The working principle and usage process of this utility model are as follows: During use, the hydraulic telescopic cylinder 105 retracts its output end. During this upward movement, multiple sets of balls 207 clamp the output end of the hydraulic telescopic cylinder 105 from various directions, creating friction between them. This causes the sleeve 201 to move upward synchronously with the output end of the hydraulic telescopic cylinder 105 until the buffer pad 3 at the top of the sleeve 201 contacts the bottom of the top plate 104. The sleeve 201 then stops moving upward due to the constraint at the top. Simultaneously, the rolling of the balls 207 does not affect the output end of the hydraulic telescopic cylinder 105 from causing the pressure plate 106 to rise until the top of the pressure plate 106 contacts the buffer pad 3 at the bottom of the sleeve 201. At this point, the device is set to its initial position, and the base 102 is fully exposed to the external environment. After placing the pressure clamp to be tested flat on top of the base 102, the hydraulic telescopic cylinder 105 is opened, causing the pressure plate 106 to move downward. During this process, the sleeve 201 moves downward synchronously due to the friction caused by the balls 207 clamping the output end of the hydraulic telescopic cylinder 105. After the sleeve column 201 slides down vertically until the bottom of the cavity column 209 and the outer frame 210 contact the top of the base plate 101, the sleeve column 201 stops moving down due to the limited bottom position of the enclosure mechanism 2. The rolling of the balls 207 on the outer wall of the output end of the hydraulic telescopic cylinder 105 does not restrict the downward pressure of the hydraulic telescopic cylinder 105. At this time, the shielding area formed by the outer frame 210 and the protective net 211 fully encloses the external area of ​​the base 102. Finally, the hydraulic telescopic cylinder 105 is opened again, causing its output end to move down between the balls 207, driving the pressure plate 106 to apply pressure to the clamp and test its load-bearing capacity. When the pressure plate 106 is moved back after the test, the sleeve column 201 is simultaneously reset, exposing the tested clamp to the external environment for direct collection by personnel. This effectively avoids the need for frequent opening and closing of the external shield. In the process of batch testing clamps, this not only simplifies the personnel's work process and reduces power input, but also ensures testing efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
