Description

Technical Field

[0001] The utility model relates to the technical field of steel strand tensioning force detection, and more specifically to a device for detecting the tensioning force of an anchor steel strand. Background Art

[0002] Steel strand is a steel product composed of multiple steel wires twisted together. The carbon steel surface can be coated with galvanized layer, zinc-aluminum alloy layer, aluminum clad layer, copper plating layer, epoxy resin coating, etc. as needed. It is commonly used in bridges, buildings, water conservancy, energy and geotechnical engineering. Before leaving the factory, the steel strand needs to be sampled and tested for its tensile strength.

[0003] Traditionally, when testing the tension of steel strands, a tensile testing machine is used to clamp the steel strands. However, the clamp needs to be screwed many times to fix the prestressed steel strands on the tensile testing machine before testing can be performed. This causes the problem that it is troublesome to clamp the prestressed steel strands with conventional tensile testing machines. In addition, it fails to achieve a certain fixing effect and one end may become loose during testing, which interrupts the testing work and requires re-fixing for testing, which is time-consuming and labor-intensive. Therefore, a detection device for the tension of anchor steel strands is designed to solve the above problems. Utility Model Content

All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The utility model provides a device for detecting the tensioning force of an anchor steel strand, comprising an operating box 101, a movable plate 107 being slidably connected inside the operating box 101, a clamping device 2 being provided on one side of the movable plate 107 and one side inside the operating box 101, three groups of movable grooves 104 being provided on one side of the movable plate 107 and one side inside the operating box 101, a clamping member 206 being slidably connected inside the movable groove 104, a card slot 207 being provided on the outer inner end of the clamping member 206, an extrusion member 208 being abutted inside the three groups of card slots 207, a steel strand body 211 being slidably connected inside the extrusion member 208, the interior of the extrusion member 208 being made of rubber material, and the interior of the outer end of the extrusion member 208 being made of elastic material.

[0021] Furthermore, a first control panel 102 and a second control panel 103 are fixedly connected to the upper surfaces of both ends of the operating box 101, and two jacks 105 are fixedly connected inside one side of the operating box 101. The second control panel 103 is electrically connected to the output end of the jack 105. The second control panel 103 can be used to control the operation of the two jacks 105, and the force output by the jack 105 can also be displayed on the second control panel 103 to increase the tension of the steel strand body 211.

[0022] Furthermore, a moving part 106 is fixedly connected to the output end of the jack 105, and the two moving parts 106 are internally stuck on the outside of the two ends of the moving plate 107. One end of the moving part 106 is fixedly connected to a moving rod 108, and the other end of the moving rod 108 is slidably connected to the outside of the guide rail 109 inside one side of the operation box 101. Scale lines 110 are also marked on both sides of the inside of the operation box 101. The scale lines 110 are located at the upper end of the guide rail 109. When the jack 105 is in operation, it controls the moving part 106 to pull the moving plate 107 to move. The guide rails 109 on both sides limit the direction of movement of the moving part 106, and the scale lines 110 are used to display the distance moved by the moving plate 107.

[0023] Furthermore, the clamping device 2 also includes a motor 201, which is placed on the upper end of the placement plate 202. One side of the placement plate 202 is fixedly connected to one side of the movable plate 107. The motor 201 is electrically connected to the first control panel 102. The first control panel 102 controls the operation of the two motors 201, thereby controlling the clamping member 206 to clamp and fix the two ends of the steel strand body 211, thereby facilitating subsequent tension detection.

[0024] Furthermore, the output end of the motor 201 is fixedly connected to a rotating plate 203, the cross-section of the rotating plate 203 is triangular, and built-in rotating grooves 204 are provided at the three end corners of the rotating plate 203. A connecting rod 205 is rotatably connected inside the rotating groove 204, and the other end of the connecting rod 205 is rotatably connected to the lower end of the clamping member 206. The rotating plate 203 rotates under the control of the motor 201, pulling the connecting rod 205 to drive the outer clamping member 206 to move toward the middle, pressurizing the extrusion member 208, thereby achieving the effect of clamping and fixing the steel strand body 211 placed in the middle of the extrusion member 208.

[0025] Furthermore, a spring 209 is fixedly connected to the lower surface of one end of the clamping member 206, and the other end of the spring 209 is fixedly connected to the inside of the movable groove 104. A damping is provided inside the spring 209. A protective plate 210 is fixedly connected to the side of the rotating plate 203 away from the motor 201, which is used to limit the movement of the clamping member 206 and prevent the clamping member 206 from moving out of the movable groove 104 during the movement process.

[0026] The working principle of the present invention is as follows: when in use, the staff places a section of the steel strand body 211 to be tested inside the operating box 101, and the two ends are placed between the two extrusion pieces 208 respectively. The first control panel 102 controls the operation of the two motors 201 to achieve the effect of controlling the rotation of the rotating plate 203, and the connecting rod 205 at the three end corners moves to one side, and the upper end of the connecting rod 205 pulls the clamping piece 206 to move inward, compressing the extrusion piece 208, thereby fixing the outer side of the internal steel strand body 211, and then the second control panel 103 controls the operation of the jack 105, the output end is recovered, and the movable plate 107 is controlled to move outward. The guide rails 109 on both sides limit the movement direction of the movable plate 107. When the movable plate 107 moves, it stretches the steel strand body 211 fixed in the middle, and the data generated by the tension is transmitted to the second control panel 103 for display. The moving distance is read from the scale line 110, thereby achieving the purpose of detecting the tension of the steel strand body 211.
