Description

TECHNICAL FIELD

[0001] The application relates to the technical field of masonry detection, and particularly relates to a masonry structure bearing capacity detection device. BACKGROUND

[0002] Masonry is formed by using mortar and other cementing materials to assemble brick and stone blocks, such as brick walls, stone walls and various block walls, and can also be simply referred to as masonry. Masonry is the main construction method of enclosing walls, and enclosing walls are prone to looseness after being blown by wind and battered by rain for a long time, so that the enclosing walls are prone to collapse in windy weather, which seriously endangers the safety of the life and property of residents. Therefore, it is very important to regularly detect the compressive strength of the enclosing walls.

[0003] In a patent file with a published announcement number CN219830611U, a masonry compressive strength detection device is provided. The device is placed into a required number of weight blocks along a limiting rod so that the weight blocks are attached to the upper surface of a sliding block, and a pressing block with a required diameter masonry contact surface is screwed into the end of the connecting rod away from the sliding block. In this way, the detection compressive strength of the masonry can be obtained under the condition that the mass of the combination of the pressing block and the sliding block is known, the masonry contact area of the pressing block is known, and the inclination angle of the sliding rail is known. The above-mentioned device does not have a height adjusting device, so that the device can only detect the compressive strength of the wall surface of the same height of the masonry, and cannot detect the compressive strength of the wall surface of different heights of the same masonry, and cannot comprehensively reflect the actual compressive strength of the entire masonry. CONTENT OF THE UTILITY MODEL

[0004] In view of the defects of the prior art, the application provides a masonry structure bearing capacity detection device, which overcomes the defects of the prior art and aims to solve the problem that the existing masonry compressive strength detection device does not have a height adjusting device, so that the device can only detect the compressive strength of the wall surface of the same height of the masonry, and cannot detect the compressive strength of the wall surface of different heights of the same masonry, and cannot comprehensively reflect the actual compressive strength of the entire masonry.

[0005] To achieve the above-mentioned purpose, the application provides the following technical scheme: a masonry structure bearing capacity detection device, comprising a support frame, a mounting frame is fixedly installed at the top of the support frame, a threaded rod is rotationally connected in the mounting frame, a driving threaded rod rotation motor one is fixedly installed at the top of the mounting frame, a moving plate is threadedly sleeved on the outer surface of the threaded rod, a guide rod is slidably inserted into the moving plate on one side of the threaded rod, the guide rod is fixedly installed in the mounting frame, an inclined plate is fixedly connected to the top of the moving plate, two guide rails are symmetrically installed on the upper surface of the inclined plate, a compression detection unit is slidably connected to the top of the guide rail, and a limiting unit for limiting the compression detection unit is arranged between the two guide rails on the upper surface of the inclined plate.

[0006] By adopting the technical scheme, the initial position of the compression resistance detection unit is fixed at the highest point of the guide rail through the limiting of the limiting unit, so as to facilitate the detection of the compression resistance of the masonry through the cooperation between the inclined plate, the guide rail and the compression resistance detection unit. The vertical height of the moving plate is adjusted to adjust the position of the compression resistance detection unit, so that the device can detect the compression resistance of the wall surface at different heights of the same masonry, and the detection result is more accurate.

When the limiting plate is retracted into the inside of the adjusting block due to the rotation of the gear, the compression resistance detection unit is no longer blocked and will slide downward along the guide rail under the action of gravity and perform compression resistance detection operation on the masonry. After the detection activity is completed, the limiting unit will move upward along the guide rail with the compression resistance detection unit under the driving action of the reciprocating screw rod and the motor two and return to the initial position.

[0016] By adopting the technical scheme, the moving plate can keep linearity and stability during movement in the mounting frame.

[0017] As a preferred technical scheme of the present application, the bottom of the support frame is fixedly provided with four locking universal wheels arranged in a linear array and uniformly distributed.
