Description

Technical Field

[0001] This utility model relates to the field of steel bar strength testing technology, and in particular to a hydraulic steel bar strength testing device for construction. Background Technology

[0002] The cold bending test is a method for determining the strength of steel bars. It tests the ability of steel bars to withstand bending deformation at room temperature. In the past, steel bar testing equipment required clamping and fixing both ends of the steel bars before bending them through a bending machine. After the test, material removal was also required. Therefore, the testing operation was complicated and the work efficiency was low.

[0003] Publication (Announcement) No. CN219810788U discloses a hydraulic rebar strength testing device for construction. Its structure includes a testing platform with a discharge trough in the center of its top surface. It also includes a first and a second feeding group positioned on either side of the discharge trough, located above it. A hydraulic bending testing mechanism is installed at the rear end of the testing platform. Through the structural design of the two feeding groups, the hydraulic bending testing mechanism, and the operating screen on the testing platform, it achieves top-to-bottom feeding and initial pressure stabilization of the material, followed by further pressure testing of the rebar strength. No manual material handling is required. This novel design eliminates the need for clamping or replacing materials during testing, making it easy to operate and highly efficient. This invention is novel, ingenious, structurally sound, and easy to operate, and is expected to generate significant social and economic benefits. It should be widely promoted and used in the market.

[0004] While the above-mentioned solution can achieve the function of pressure testing of the strength of the pressed steel bars, the size of the feeding trough of the feeding component is fixed, which limits the applicable steel bar size, and the steel bar feeding is easily obstructed. Therefore, we propose a hydraulic steel bar strength testing device for construction. Utility Model Content

[0005] The main purpose of this utility model is to provide a hydraulic steel bar strength testing device for construction. By setting up an adjustment unit and a feeding unit, it solves the problems of the feeding component having a fixed feeding trough size that limits the applicable steel bar size and the steel bar feeding being easily obstructed.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a hydraulic steel bar strength testing device for construction, including a bearing platform and a pressing unit, and further including an adjustment unit and a feeding unit set on the bearing platform;

[0007] The adjustment unit includes a lead screw, a servo motor, a support block, and a support block. A rectangular through slot is provided at the center of the top surface of the bearing platform. A strip-shaped mounting slot is provided on each of the two opposite sides of the rectangular through slot. The lead screw is movably mounted on one of the strip-shaped mounting slots. The servo motor is mounted on the side of the bearing platform and its output end is connected to the end face of the lead screw. There are four support blocks in total, which are divided into two groups. The two groups of support blocks are located on the two strip-shaped mounting slots respectively. One group of support blocks is respectively matched with the two symmetrically arranged positive and negative threads on the lead screw. A support block is fixedly provided between every two support blocks located on the same vertical center horizontal plane.

[0008] The feeding unit includes an inclined limiting block, an inclined sliding rod, and an inclined roller. Every two inclined limiting blocks form a group and are fixedly arranged relative to each other on the top surface of a support block. An inclined mounting groove is provided on the slope of the inclined limiting block facing the vertical central axis of the support block. The inclined sliding rod is fixedly arranged on the inclined mounting groove, and the inclined roller is movably sleeved on the outer circumferential surface of the inclined sliding rod.

[0009] Preferably, the adjustment unit further includes a guide rod, which is fixedly mounted on another strip-shaped mounting groove and movably passes through another set of support blocks.

[0010] Preferably, the inclined slide bar and the inclined roller are arranged in a one-to-one correspondence with the inclined limiting block.

[0011] Preferably, the pressing unit includes a support arm, a hydraulic cylinder, a pressure sensor, and a pressing block. The support arm is fixedly mounted on the top surface of the support platform, the hydraulic cylinder is embedded in the top surface of the support arm, the pressure sensor is mounted on the output end of the hydraulic cylinder, and the pressing block is mounted on the bottom surface of the pressure sensor and is in the shape of an inverted "V".

[0012] Preferably, a controller is fixedly installed on the top surface of one side of the support platform.

[0013] Preferably, the support platform is fixedly provided with legs at the corners of its bottom surface.

[0014] Compared with the prior art, the hydraulic steel reinforcement strength testing device for construction of this utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting an adjustment unit, the servo motor can control the screw to rotate forward and backward in the strip mounting groove on the bearing platform. Two of the support blocks, which are threaded to the screw, move relative to each other under the force, which can drive the flexible support block to adjust the spacing in the rectangular through groove. The other two support blocks can slide and translate on the guide rod to cooperate with the adjustment of the support block and provide auxiliary support. When the two support blocks are brought closer together, they can provide bottom support for the test steel bar. When the two support blocks are separated, the test steel bar loses the bottom support and can be dropped in the rectangular through groove. The equipment makes the dropping operation of the test steel bar simple and smooth.

[0016] 2. In this utility model, by setting up a feeding unit, two inclined limiting blocks are set as a group and are fixedly positioned relative to each other on the top surface of a support block, forming a feeding area similar to a "V" shape on the top surface of the support block. The inclined sliding rods installed one-to-one in the inclined limiting blocks through the inclined mounting grooves can cooperate with the inclined rollers to maintain an inclined state. Test steel bars of various sizes can be placed between the two relatively set inclined rollers. After the two support blocks are separated, the inclined rollers can rotate on the inclined sliding rods to cooperate with the test steel bars to move away from the inclined rollers. The feeding component of the equipment is applicable to a wider range of steel bar sizes and is more flexible in use. Attached Figure Description
