Description

Technical Field

[0001] This utility model relates to the field of tie rod welding strength testing technology, and in particular to a testing tool for testing the welding strength of belt conveyor tie rods. Background Technology

[0002] Logistics and transportation are one of the manifestations of the high-efficiency labor mode in modern society. The logistics sorting system is an important medium for achieving efficient and convenient delivery of goods and information in logistics / express delivery services. It is an important technical means for the circulation of production materials and commodities, and its economy and efficiency directly affect the circulation cost of commodities.

[0003] A belt conveyor is a continuous conveying machine that uses a flexible conveyor belt as the load-bearing and traction component for goods. Due to its advantages such as simple structure, stable and reliable operation, strong adaptability to various goods, large conveying capacity, and low power consumption, belt conveyors are widely used in logistics for transporting goods.

[0004] Currently, the supports used in belt conveyors mainly consist of vertical support legs symmetrically arranged on both sides of the belt conveyor and tie rods connecting the vertical support legs. The tie rods are mainly used to increase the support strength of the vertical support legs for the belt conveyor. However, in the existing technology, after the tie rods are welded, they are directly installed between the two vertical support legs. After long-term use, the tie rods are very prone to breakage at the weld joint, which cannot ensure effective support for the belt conveyor. In addition, there are no tools to test the welding strength of the tie rods after welding, which cannot ensure that the welding strength of each tie rod leaving the factory meets the user's requirements, causing great inconvenience to the support work of the belt conveyor. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model aims to provide a testing fixture for detecting the welding strength of belt conveyor tie rods. This fixture has a reasonable overall design, simple structure, and convenient operation. After the tie rod is welded, it can effectively test the welding strength of the welded tie rod, ensuring that the welding strength of each welded tie rod meets the user's requirements. This prevents the tie rod from breaking at the weld joint during use, reduces safety hazards, improves the stability of the belt conveyor support, and brings great convenience to the belt conveyor support work.

[0026] like Figures 1-4 As shown in the figure, this application provides a testing fixture for testing the welding strength of a belt conveyor tie rod, including: a base 100, a first welding strength testing piece 200, and a second welding strength testing piece 300.

[0027] The base 100 is placed on the platform where the inspector needs to test the welding strength of the welded tie rod 400. The base 100 is rectangular in shape and its length is greater than the length of the tie rod that needs to be tested for welding strength, so that the tie rod 400 can be fixed on it for welding strength inspection.

[0028] When the first welding strength testing piece 200 is used to test the welding strength of the completed tie rod 400, the first fixing ear 420 welded to one end of the tie rod body 410 is fixedly installed on its upper part by fixing bolts 700. The first welding strength testing piece 200 is fixedly set on one side of the upper surface of the base 100.

[0029] When the second welding strength testing piece 300 is used to test the welding strength of the completed tie rod 400, the second fixing ear 430 welded to the other end of the tie rod body 410 is set on its upper part by the welding strength testing bolt 500, and the second welding strength testing piece 300 is fixedly set on the other side of the upper surface of the base 100.

[0030] The first welding strength testing component 200 includes a first testing plate 210, which is fixedly installed on one side of the upper surface of the base 100. The first testing plate 210 has first fixing holes symmetrically provided on both sides, corresponding to the first through holes provided on both sides of the first fixing ears 420. When testing the welding strength of the welded tie rod 400, the first fixing ears are fixedly installed on the first testing plate 210 by passing the fixing bolts 700 through the first through holes and the first fixing holes, and the first fixing ears 420 are in contact with the first testing plate 210.

[0031] Symmetrical reinforcing plates 220 are provided on both sides of the first detection plate 210 to improve its overall strength. The first reinforcing plates 220 are generally triangular and welded to both sides of the first detection plate 210. The first reinforcing plates 220 can effectively prevent the first detection plate 210 from deforming when the tie rod 400 is checked for welding strength, and further improve the overall tensile strength of the first detection plate 210.

[0032] The second welding strength testing component 300 includes a second testing plate 310, which is fixedly installed on the other side of the upper surface of the base 100. The second testing plate 310 has second fixing holes symmetrically provided on both sides, corresponding to the second through holes provided on both sides of the second fixing ears 430. When testing the welding strength of the welded tie rod 400, the welding strength testing bolt 500 passes through the second through hole and the second fixing hole to fix the second fixing ears on the second testing plate 310. There is a certain gap between the second fixing ears 430 and the second testing plate 310.

[0033] Symmetrical second reinforcing plates 320 are provided on both sides of the second detection plate 310 to improve its overall strength. The second reinforcing plates 320 are generally triangular and welded to both sides of the second detection plate 310. The second reinforcing plates 320 can effectively prevent the second detection plate 310 from deforming when the tie rod 400 is checked for welding strength, and further improve the overall tensile strength of the second detection plate 310.

[0034] The welding strength testing bolt 500 includes a welding strength testing screw 510 with a length greater than the gap between the second fixing lug 430 and the second testing plate 310, and a strength testing nut 520 that mates with the welding strength testing screw 510 is provided at the end of the welding strength testing screw 510.

[0035] At least one support member is provided on the base 100 between the first welding strength test member 200 and the second welding strength test member 300 to effectively support the tie rod body 410 of the welded tie rod. In this embodiment, there are two support rods.

[0036] The support includes a support plate 600, which is mounted on the base 100. A support positioning groove 610 is provided at the upper end of the support plate 600 to prevent the pull rod body from sliding along its width direction. The support positioning groove 610 is U-shaped in general.

[0037] The specific testing method of this utility model is as follows:

[0038] When checking the welding strength of the completed tie rod, first place the tie rod body on the support positioning groove of the support plate, then fix the first fixing lug to the first test plate with fixing bolts, and then use a torque electric wrench to turn the strength test nut and the welding strength test screw to fix the second fixing lug to the second test plate until the torque reaches the set value, which is 80-100 N·m. After reaching the set torque value, maintain it for the set time. If the completed tie rod does not break within the set time, it proves that the completed tie rod is qualified; if it breaks, it is unqualified.

[0039] In summary, this utility model has a reasonable overall design, simple structure, and convenient operation. After the tie rod is welded, its welding strength can be effectively tested to ensure that the welding strength of each welded tie rod meets the user's requirements. This avoids breakage of the tie rod at the weld point during use, reduces safety hazards, improves the stability of the belt conveyor support, and brings great convenience to the belt conveyor support work.
