Description

Technical Field

[0001] The utility model relates to the technical field of tensile force detection, and more specifically, to a raw material tensile force detection device for engineering detection. Background Art

[0002] Tensile force detection is one of the items for detecting the quality of engineering materials, and a tensile force detection device is required to complete the detection operation. Two sets of clamps are arranged on the tensile force detection device, which respectively clamp and fix both ends of the material to be tested. When the two sets of clamps move away from each other, the material to be tested can be stretched, and the real-time tensile force value on the material to be tested is measured by a sensor.

[0003] At present, before engineering materials are used, it is necessary to conduct compressive strength detection to prevent the compressive strength of the materials from being insufficient after use, which affects the overall strength of the building. For example, for the tensile strength detection of steel wires, before detecting the tensile strength of materials with an arc-shaped surface such as steel wires, it is necessary to fix both ends of them. However, due to the arc-shaped surface structure of their outer surface, when the traditional clamp clamps the steel wire, it is easy for the two ends of the steel wire to slip off from the clamp during the detection process due to excessive tensile force, which affects the smooth progress of the detection process. In view of this, we propose a raw material tensile force detection device for engineering detection. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a raw material tensile force detection device for engineering detection, so as to solve the technical problem that when the traditional clamp clamps the steel wire, it is easy for the two ends of the steel wire to slip off from the clamp during the detection process due to excessive tensile force, which affects the smooth progress of the detection process.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A raw material tensile force detection device for engineering detection, including a base symmetrically configured with U-shaped frames at the top;

[0006] A sliding table is movably and vertically arranged between the U-shaped frames, and a top plate is detachably installed between the tops of the U-shaped frames;

[0009] The clamping member includes symmetrically arranged clamping arm member B and clamping arm member A;

[0010] The clamping arm component B includes a clamping arm B, the clamping arm component A includes a clamping arm A, and a groove is formed inside each of the clamping arm A and the clamping arm B;

[0011] The pressing component includes a grip rod with a sector gear connected to one end thereof;

[0012] The pushing component includes a movable rod with a pushing disk arranged at the top thereof. The pushing disk is arranged inside the groove. A tooth groove is formed on one side of the movable rod, and the sector gear is movably engaged with the tooth groove.

[0013] By designing the clamping assembly, the two ends of the steel wire can be respectively placed inside the clamping seat in the present utility model. By pressing the grip rod, the movable rod is driven to rise through the engagement between the sector gear and the tooth groove, so as to jack up the clamping arm B and the clamping arm A through the pushing disk, and thus the two ends of the steel wire are clamped by the clamping arm component B and the clamping arm component A. Also, because the V-shaped groove is a V-shaped groove structure, the diameters of the clamping arm component B and the clamping arm component A gradually decrease from bottom to top, so as to achieve a stable clamping effect on the steel wire.

[0014] Preferably, a V-shaped cavity is formed in the middle on the side of the clamping arm B facing the clamping arm component A, and V-shaped teeth are formed inside the V-shaped cavity;

[0015] On the top and bottom of the side of the clamping arm A facing the clamping arm B, clamping blocks are symmetrically formed. A V-shaped notch is formed between the clamping blocks, and anti-slip teeth are formed on the inner wall of the V-shaped notch of the clamping blocks.

[0016] Preferably, the clamping block arranged at the top on one side of the clamping arm A is arranged obliquely upward, and the clamping block arranged at the bottom on one side of the clamping arm A is arranged obliquely downward.

[0017] Preferably, on one side of the V-shaped groove, obliquely guiding grooves communicating with the V-shaped groove are symmetrically formed. Guide rods inserted into the obliquely guiding grooves are formed on one side of each of the clamping arm B and the clamping arm A. On one side of the clamping seat, baffles are symmetrically and detachably installed, and one side of each baffle abuts against the clamping arm B and the clamping arm A.

[0018] Preferably, on the bottom of one side of the clamping seat, fixing blocks are symmetrically and detachably installed. A lug is formed in the middle on one side of each fixing block, a connecting shaft is fixedly connected between the lugs, and a shaft hole for rotatably sleeving on the outer edge surface of the connecting shaft is formed inside the sector gear.

[0019] Preferably, a first mounting cylinder is centrally arranged on the top of the sliding table, a second mounting cylinder is centrally arranged on the bottom of the top plate, and convex shafts are formed at one ends of the clamping seats arranged on the sliding table and the top plate, and the convex shafts are respectively detachably installed inside the first mounting cylinder and the second mounting cylinder.

[0020] Preferably, a motor is detachably installed on one side of the upper end surface of the top plate. The motor is connected by a motor shaft to a lead screw that is rotatably installed between the top plate and the base. A positioning rod is fixedly installed on one side of the base and the top plate away from the lead screw. A positioning hole sleeved on the positioning rod is opened inside one end of the sliding table, and the other end of the sliding table is movably engaged with the lead screw.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] 1. By designing the clamping assembly, both ends of the steel wire can be respectively placed in the clamping seat, and by pressing the grip rod, the movable rod is driven to rise through the engagement of the sector gear and the tooth groove, so as to jack up the clamping arm B and the clamping arm A through the top push plate, and then the two ends of the steel wire are clamped by the clamping arm component B and the clamping arm component A. Also, because the V-shaped groove is a V-shaped groove structure, the caliber of the clamping arm component B and the clamping arm component A gradually decreases from bottom to top, so as to achieve a stable clamping effect on the steel wire, solving the problem that in the traditional fixture, after clamping the steel wire, the two ends of the steel wire are likely to slip off from the fixture due to excessive pulling force during the detection process, affecting the smooth progress of the detection process.

[0023] 2. The present utility model also designs a clamping block, and the clamping block arranged at the top of one side of the clamping arm A is arranged obliquely upward, and the clamping block arranged at the bottom of one side of the clamping arm A is arranged obliquely downward, which can achieve an inclined clamping effect on the steel wire. And because both the clamping arm A and the clamping block are arranged obliquely, during the process of tensile testing after clamping the steel wire, the pressure of the clamping arm A and the clamping block on the steel wire will generate a component force in the same direction as the frictional force in the axial direction of the steel wire, and with the action of the frictional force, it can further achieve a stable clamping effect on the steel wire.
