Description

Technical Field

[0001] The utility model relates to the technical field of roads and bridges, in particular to a road and bridge support detection device. Background Art

[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. They are located between the bridge and the pad stone. They can reliably transfer the load and deformation (displacement and rotation) borne by the superstructure of the bridge to the substructure of the bridge. They are important force transmission devices of the bridge and are of two types: fixed bearings and movable bearings.

[0003] For example, a road bridge bearing detection device with announcement number CN219552053U is provided with a clamping mechanism, which can automatically clamp and fix the road bridge bearing. The staff only needs to control the control panel to control the clamping mechanism to clamp and fix the road bridge bearing, which solves the problem of manual operation of the bridge bearing in the original detection device to clamp and fix the bearing, and the operation process is simple. However, when performing a compressive test on the compressive test block, the clamping mechanism clamps the test block from the side, which will have a certain impact on the compressive strength of the test block. The bridge bearing often has no side support when in use. Testing with side support will result in the detected strength being higher than the strength during actual use, affecting the accuracy of the test data. For this reason, a road bridge bearing detection device is proposed for improvement. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] To this end, one purpose of the utility model is to provide a road bridge support detection device to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned object, an embodiment of the utility model provides a road bridge bearing detection device, comprising a base, a bracket is fixedly connected to the top of the base, a vertical driving member is arranged on the bracket, a pressure detection block is fixedly connected to the output end of the vertical driving member, and an extrusion piece is arranged on the side of the pressure detection block;

[0007] The base is provided with a slide groove, in which a bidirectional screw rod and a unidirectional screw rod arranged perpendicular to each other are rotatably connected, the bidirectional screw rod and the unidirectional screw rod are provided with mutually meshing bevel gears, and the bidirectional screw rod and the unidirectional screw rod are both threadedly connected with a slider;

[0008] The top surface of the slider is fixedly connected to a vertical plate, a push rod is inserted on the vertical plate, the end of the push rod is fixedly connected to a clamping ring, a spring is provided between the clamping ring and the vertical plate, the other end of the push rod is fixedly connected to a clamping plate, and the top of the clamping plate is fixedly connected to a pressure plate.

[0009] Preferably, any of the above solutions is that a control panel is provided on one side of the base, and the bracket is provided in the middle of the top surface of the base.

[0010] Preferably, any of the above schemes is that the extrusion piece adopts an L-shaped structure and the outer side surface of its vertical section adopts an inclined surface, and a pressure sensor is arranged in the pressure detection block.

[0011] The above technical solution is adopted: the base provides support for the upper structure and a platform for testing. The control panel arranged on its side is used to control the operation of the motor and the vertical drive component. The bracket provides an installation platform for the vertical drive component, so that it can obtain a certain height, which is convenient for it to drive the pressure detection block to move vertically. The pressure detection block is used to squeeze the compression test block of the bridge support to test the compressive strength of the test block. The extrusion piece is used to push open the splint so that the side of the compression test block will not be supported by the splint when the pressure detection block is testing the compression test block.

[0012] Preferably, any of the above schemes adopts a cross-shaped structure, and there are two unidirectional screw rods which are symmetrically arranged on both sides of the bidirectional screw rod.

[0013] Preferably, any of the above schemes is that a motor is provided at one end of the bidirectional lead screw, and two sliding blocks are symmetrically arranged on the bidirectional lead screw.

[0014] The above technical solution is adopted: the slide groove provides installation space for the bidirectional screw and the unidirectional screw, and provides activity space for the slider. By setting mutually meshing bevel gears on the bidirectional screw and the unidirectional screw, the unidirectional screw and the bidirectional screw can rotate synchronously. When the bidirectional screw and the unidirectional screw rotate synchronously, multiple sliders move toward or away from each other synchronously, thereby driving the vertical plate, the clamping plate and other structures to move synchronously. The motor provides power to the bidirectional screw to drive it to rotate.

[0015] Preferably, in any of the above schemes, the push rod is arranged horizontally, and the spring is sleeved on the push rod.

[0016] Preferably, any of the above schemes is provided with a buffer pad on the inner side of the clamping plate, and the pressure plate is arranged obliquely.

[0017] The above technical solution is adopted: the vertical plate provides support for the push rod, the push rod provides an installation platform for the splint, and can drive it to move. When performing the test work, the test block is placed on the base. The starting motor drives the bidirectional screw to rotate, and the bidirectional screw drives the unidirectional screw to rotate through the bevel gear, so that all the sliders drive the splints to move synchronously to clamp the test block. Then start the vertical drive component to drive the pressure detection block to move downward. Before the pressure detection block contacts the test block, the extrusion piece first contacts the pressure plate and squeezes the pressure plate to the side. The pressure plate drives the splint and the push rod to move outward, the spring is stretched, and the splint detaches from the side of the test block. The pressure detection block continues to move downward to detect the test block.

[0018] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0019] 1. The road bridge support detection device is provided with a pressure detection block, an extrusion, a slide, a bidirectional screw, a unidirectional screw, a bevel gear, a slider, a vertical plate, a push rod, a snap ring, a spring, a clamp, a pressure plate and other structures. When performing the detection work, the test block is placed on the base, the motor is started to drive the bidirectional screw to rotate, and the bidirectional screw drives the unidirectional screw to rotate through the bevel gear, so that all the sliders drive the clamps to move synchronously to clamp the test block. Then the vertical driving component is started to drive the pressure detection block to move downward. Before the pressure detection block contacts the test block, the extrusion first contacts the pressure plate and presses the pressure plate to the side. The pressure plate drives the clamp and the push rod to move outward, the spring is stretched, and the clamp is separated from the side of the test block. The pressure detection block continues to move downward to detect the test block. Before the detection, the clamp pushes the test block to the right below the pressure detection block and constrains it. Before the pressure detection block contacts the test block, the clamp is withdrawn, so that the condition of the test block during the detection is the same as that during use, which can make the detection data more accurate.

[0020] 2. The road bridge support detection device, by setting a bevel gear between the bidirectional screw and the unidirectional screw for transmission, enables multiple screws to rotate synchronously, without setting multiple driving parts for separate driving, and is more convenient to use. By setting a snap ring at the end of the push rod and cooperating with a spring, after completing a test, the spring will release the elastic force to drive the splint to reset, which is convenient for the next test.
