Description

Technical Field

[0001] The utility model belongs to the technical field of crossbeam detection devices, and particularly relates to a deformation detection device for building crossbeams. Background Technique

[0002] The crossbeam is one of the skeletons of a building and is the basic framework of the building. It has structural forms such as steel beams and concrete beams. To a certain extent, the structural strength of the crossbeam determines the structural strength of the building. In order to ensure the reliability of the building, relevant inspections need to be carried out on the crossbeam. Among them, the deformation detection of the crossbeam is particularly important.

[0003] The Chinese patent with the publication number CN221199215U discloses a steel beam deformation detection device, which includes a bottom plate, a side plate, a workpiece, two pressing blocks, two bottom blocks and four limiting plates. The rear side of the top of the bottom plate is fixedly connected to one side of the bottom of the side plate. The side plate is in an L shape. A hydraulic cylinder is fixedly connected to the other side of the bottom of the side plate. The four limiting plates are respectively arranged on the tops of the two pressing blocks. Through the adjusting mechanism and the fixing mechanism, the device can test workpieces of different sizes, expand the application range of the device, and thus increase the practicability of the device. And during the test, the moving plate can be fixed to ensure the normal test of the workpiece.

[0004] However, in the actual use process, the fixing mechanism drives the fixing plate to move by rotating the rotating column, so as to abut and limit the moving plate. As the position of the moving plate changes, it is necessary to frequently rotate the rotating columns on both sides, and the rotation process is labor-consuming and time-consuming, which is not conducive to actual use. In summary, the use steps of the above solution are relatively cumbersome and not conducive to actual use. Content of the Utility Model

[0005] The utility model aims to provide a deformation detection device for building crossbeams to solve the problem that the existing technology has relatively cumbersome use steps mentioned above.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A deformation detection device for building crossbeams, including

[0007] A bottom plate, on which a side plate is installed, and a hydraulic cylinder is installed on the side plate;

[0008] A moving plate, which is slidably installed on the bottom plate;

[0009] A clamping unit, which is installed on the moving plate;

[0010] A positioning unit, which includes two positioning components symmetrically arranged with respect to the moving plate. Each positioning component includes a mounting plate and an insertion plate. The mounting plate is fixed to the side wall of the moving plate. The mounting plate is in sliding contact with the side wall of the bottom plate. A jack is provided on the side wall of the bottom plate. The insertion plate is inserted on the mounting plate, and the end of the insertion plate is adapted to the jack.

[0011] Principle and effect of this technical solution:

[0012] 1. By providing mounting plates on both sides of the moving plate, the movement of the moving plate on the bottom plate is more stable. And through the setting of the plug board and the jack, when the moving plate needs to be positioned at a specified position, only need to insert the plug board into the jack to complete the positioning of the moving plate. And when it is necessary to release the positioning, pull the plug board away from the jack to release the limit on the moving plate, which is more simple and convenient to operate and saves manpower.

[0013] 2. Through the setting of the clamping unit, it can play a clamping function on building cross beams such as steel beams to be detected, and the movable end of the hydraulic cylinder is used to pressurize the steel beam for detection, so as to obtain the anti-deformation ability of the steel beam, that is, the bending resistance. And by moving the moving plate, the position of the clamping unit can be changed, so that it is easier to install or disassemble the steel beam relative to the clamping unit.

[0014] The present utility model is further configured as: The positioning assembly further includes a mounting cylinder, a pressing plate and a spring. The mounting cylinder is fixed on the side wall of the mounting plate. The pressing plate is slidably fitted in the mounting cylinder. The plug board is slidably inserted into the mounting cylinder, and the pressing plate is sleeved and fixed on the plug board. The spring is installed in the mounting cylinder and is located on the side of the pressing plate away from the mounting plate.

[0015] Principle and effect of this technical solution: The mounting cylinder limits and guides the pressing plate and the spring, so that the pressing plate will spontaneously approach the side of the mounting plate without external force. And the pressing plate is sleeved on the plug board, that is, it drives the plug board to spontaneously approach the bottom plate. Then when the plug board is pulled out and misaligned with the jack, the plug board slides and abuts against the side wall of the bottom plate. When the moving plate moves to make the plug board correspond to the jack, the plug board is spontaneously inserted into the jack under the drive of the spring to limit the moving plate, thus saving the operation of the staff actively limiting the plug board, and the operation is more simple and convenient.

[0016] The present utility model is further configured as: The positioning assembly further includes a pull ring, and the pull ring is fixed to the end of the plug board away from the bottom plate.

[0017] Principle and effect of this technical solution: Through the setting of the pull ring, it is easier for the operator to control the plug board to move away from the jack, and thus it is easier to release the limit of the plug board on the moving plate.

[0018] The present utility model is further configured as: The clamping unit includes two clamping assemblies symmetrically arranged with respect to the moving plate. Each clamping assembly includes a placement table, two clamping plates and a transmission pair. The placement table is fixed on the moving plate. The two clamping plates are symmetrically arranged on the placement table. The transmission pair is installed in the placement table and is used to drive the clamping plates to move.

[0019] Principle and effect of this technical solution: By arranging the placement table on the moving plate, the placement plate can be synchronously moved by moving the moving plate, which is convenient for installing or disassembling the steel beam on the placement table. And by driving the two clamping plates to move relatively through the transmission pair, the distance between the two clamping plates can be adjusted according to the size of the steel beam, so as to adapt to more models of steel beams.

[0020] The utility model is further configured as: The transmission pair includes an electric push rod, a push block and a wedge block. A driving groove is formed on the placement table. A wedge block is fixed at the bottom of the clamping plate. The wedge block is slidably installed in the driving groove. A clamping groove is formed on the inclined surface of the wedge block. A clamping block is fixed on the side wall of the push block. The clamping block is slidably matched with the clamping groove, and the side wall of the push block is slidably abutted against the inclined surface of the wedge block. The push block slides in the driving groove. The electric push rod is fixed in the moving plate. The movable end of the electric push rod extends into the driving groove and is fixed to the bottom of the push block.

[0021] Principle and effect of this technical solution: The bottom of the push block is connected to the movable end of the electric push rod. Therefore, the electric push rod can push the push block to move up and down in the driving groove. And the side wall of the push block is abutted against the inclined surface of the wedge block. At the same time, the clamping block is slidably matched in the clamping groove. Therefore, as the push block rises and falls, the wedge block needs to move horizontally to adapt to the change in the horizontal dimension of the push block. By restricting the horizontal sliding of the wedge block in the driving groove, the clamping plate on the wedge block can be indirectly controlled by the electric push rod to perform horizontal displacement, that is, synchronously control the two clamping plates to approach or move away from each other.

[0022] The utility model is further configured as: A notch is formed in the side wall of the driving groove along the horizontal direction. A limiting strip is fixed on the side wall of the wedge block. The limiting strip is slidably matched with the notch.

[0023] Principle and effect of this technical solution: Through the cooperation of the limiting strip and the notch, the wedge block can only slide horizontally in the driving groove. Therefore, when the push block and the clamping block are driven by the electric push rod to rise and fall, the wedge block will not move up and down, but only slide horizontally, thus ensuring the reliability of the moving path of the wedge block. And the notch can guide the sliding of the limiting strip.

[0024] The utility model is further configured as: The cross section of the clamping plate is L-shaped, and the bottom surface of the clamping plate is slidably abutted against the top surface of the placement table.

[0025] Principle and effect of this technical solution: By making the clamping plate L-shaped, when the clamping plate clamps the steel beam to be detected, the torque brought by the reaction force can be borne and shared by the ground, thereby improving the clamping ability of the clamping plate.
