Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and in particular to a testing device for prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods.

[0003] Chinese Patent No. CN221811728U discloses a prefabricated building testing device, including a base. A fixing block is fixedly connected to the inner left side of the base. A bidirectional screw is rotatably installed inside the fixing block. Two sets of threaded sleeves are threaded to the front and rear sides of the bidirectional screw. A clamping block is fixedly connected to the lower end of the threaded sleeve. An anti-slip pad is provided on the inner wall of the opposite side of the clamping block. A knob is fixedly connected to the rear side of the bidirectional screw. This invention uses a U-shaped clamping block to clamp and fix concrete test blocks. The anti-slip pad inside the clamping block increases the friction between the test block and the clamping block during the compression process, preventing the test block from sliding and preventing excessive clamping force that could damage the test block and affect the testing. In addition, a collection box is provided to collect debris generated during the testing of unqualified test blocks. The internal collection groove is wider at the top and narrower at the bottom for easy debris collection.

[0004] However, the above technical solution has the following shortcomings: when using the equipment to test the quality of concrete test blocks, the equipment can only clamp the test block in a fixed position and press the pressure block on the fixed position of the concrete test block, thus making it impossible to test the stress limit at different positions of the test block. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a prefabricated building testing device that uses a motor a to drive a conveyor belt to move and allows a cooperating drive component to drive multiple universal ball bearings to rotate in other directions to adjust the orientation of the test block, thereby improving the versatility of the equipment.

[0006] The technical solution of this utility model is a testing device for prefabricated buildings, comprising: a frame on which testing components are mounted; a steering mechanism mounted on the frame, the steering mechanism including a mounting frame mounted on the frame, and a universal moving component and a cooperating drive component mounted on the frame and the mounting frame; the universal moving component including a motor a mounted on the frame, a drive roller a and multiple driven rollers a mounted on the mounting frame, a conveyor belt mounted on the drive roller a and the multiple driven rollers a, multiple mounting blocks mounted on the conveyor belt, and a universal ball bearing mounted on each of the multiple mounting blocks; the cooperating drive component making rolling contact with the multiple universal ball bearings; and a clamping component placed on the multiple universal ball bearings.

[0007] Preferably, the detection assembly includes a hydraulic cylinder mounted on a frame, a mounting plate connected to the output end of the hydraulic cylinder, a pressure block detachably mounted on the mounting plate, and a plurality of nuts threadedly connected to the pressure block.

[0010] Preferably, a lifting plate is slidably mounted on the sub-frame, and a drive assembly is also mounted on the sub-frame, with the output end of the drive assembly connected to the lifting plate.

[0011] Preferably, the clamping assembly includes a base plate placed on a plurality of omnidirectional balls, a bidirectional lead screw rotatably mounted on the base plate, a handwheel coaxially mounted on the bidirectional lead screw, two clamping plates threadedly connected to each other on the bidirectional lead screw, a plurality of rollers mounted on the clamping plates, and a plurality of infrared emitters mounted on the base plate, wherein the plurality of rollers are in rolling contact with the base plate.

[0021] Example 1

[0022] like Figures 1-6As shown, this embodiment proposes a testing device for prefabricated buildings, including a frame 1, a steering mechanism 8, and a clamping assembly 6. The testing assembly is mounted on the frame 1. The steering mechanism 8 is mounted on the frame 1 and includes a mounting frame 81 mounted on the frame 1, a universal moving assembly 82 and a cooperating drive assembly 83 mounted on the frame 1 and the mounting frame 81. The mounting frame 81 has a discharge trough 811. After the concrete test blocks are tested, some of the concrete fragments scattered from the poor-quality test blocks will be transported to the discharge trough 811 by the universal moving assembly 82. The fragments will fall onto the receiving plate 9 placed on the frame 1, thereby reducing the cleaning difficulty for the user.

[0023] The omnidirectional moving assembly 82 includes a motor a821 mounted on the frame 1, a drive roller a822 and multiple driven rollers a823 rotatably mounted on the mounting frame 81, a conveyor belt 824 mounted on the drive roller a822 and multiple driven rollers a823, multiple mounting blocks 825 mounted on the conveyor belt 824, and one omnidirectional ball bearing 826 mounted on each of the multiple mounting blocks 825; the cooperating drive assembly 83 rolls in contact with the multiple omnidirectional ball bearings 826; the clamping assembly 6 is placed on the multiple omnidirectional ball bearings 826, preferably with two driven rollers a823, and the drive roller a822 and the two driven rollers a823 cooperate to form a triangle, thereby leaving sufficient space for the cooperating drive assembly 83.

[0024] In this embodiment, the user clamps the test block onto the clamping assembly 6 and places the clamping assembly on multiple universal balls 826. Then, according to the user's specific testing requirements, the user drives the cooperating drive assembly 83 and the motor a821. The motor a821 drives the conveyor belt 824 to move the clamping assembly 6 on the multiple universal balls 826. The cooperating drive assembly 83 further adjusts the orientation of the clamping assembly 6, moving the test point of the test block below the test assembly, thereby increasing the testing range of the equipment.

[0025] Example 2

[0026] like Figure 1 and Figure 2 As shown, this embodiment proposes a testing device for prefabricated buildings. Compared with the first embodiment, in this embodiment, the testing components include a hydraulic cylinder 2 mounted on a frame 1, a mounting plate 3 connected to the output end of the hydraulic cylinder 2, a pressure block 4 detachably mounted on the mounting plate 3, and a plurality of nuts 5 threadedly connected to the pressure block 4.

[0027] The mounting plate 3 has multiple fixing grooves 31 distributed along a ring, and the pressure block 4 has multiple threaded rods distributed along a ring. The multiple threaded rods are distributed one-to-one with the multiple fixing grooves 31, and multiple nuts 5 are distributed on the multiple threaded rods and threadedly connected.

[0028] In this embodiment, the user removes the test block from the multiple threaded rods by turning multiple nuts 5 according to the test requirements of the test block. Then, the pressure block 4 that meets the user's needs is placed on the mounting plate 3, and the multiple threaded rods of the pressure block 4 pass through the multiple fixing grooves 31. Then, multiple nuts 5 are threaded onto the pressure block 4 to prevent the pressure block 4 from moving at will and to improve the versatility of the equipment.

[0029] Example 3

[0030] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a testing device for prefabricated buildings. Compared to Embodiment 1, in this embodiment, the driving assembly 83 includes a motor b831 mounted on the frame 1, a bevel gear a832 connected to the output end of the motor b831, a sub-frame 833 mounted on the mounting frame 81, a drive roller b834 and a driven roller b836 rotatably mounted on the sub-frame 833, a drive belt 837 mounted on the drive roller b834 and the driven roller b836, and a bevel gear b835 coaxially mounted on the drive roller b834. The drive belt 837 is drivenly connected to multiple universal ball bearings 826, and the bevel gear a832 is meshed with the bevel gear b835. A lifting plate is slidably mounted on the sub-frame 833, and the driving assembly is also mounted on the sub-frame 833, with the output end of the driving assembly connected to the lifting plate.

[0031] In this embodiment, motor b831 drives bevel gear a832 to rotate, bevel gear a832 meshes and drives bevel gear b835 to rotate, bevel gear b835 in turn drives drive roller b834 to rotate. During the movement of drive belt 837, drive component drives lifting plate to abut against drive belt 837, increasing the friction between drive belt 837 and multiple universal balls 826, allowing drive belt 837 to drive universal balls 826 to rotate more stably, thus improving the stability of clamping component movement.

[0032] Example 4

[0033] like Figure 1 and Figure 3 As shown, this embodiment proposes a testing device for prefabricated buildings. Compared with Embodiment 1, in this embodiment, the clamping assembly 6 includes a base plate 61 placed on multiple universal ball bearings 826, a bidirectional lead screw 62 rotatably mounted on the base plate 61, a handwheel 63 coaxially mounted on the bidirectional lead screw 62, two clamping plates 64 threadedly connected to each other on the bidirectional lead screw 62, multiple rollers 65 mounted on the clamping plate 64, and multiple infrared emitters 66 mounted on the base plate 61. It is optimal to have two infrared emitters 66, with the infrared rays emitted by the two infrared emitters 66 being perpendicular to each other, and all the rollers 65 rolling in contact with the base plate 61.

[0034] In this embodiment, the user places the test block on the base plate 61 and turns the handwheel 63 by hand. The handwheel 63 drives the bidirectional lead screw 62 to rotate. The bidirectional lead screw 62 drives the two clamping plates 64 to slide relative to each other or back to back until both clamping plates 64 are in contact with the test block. Then the adjustment mechanism is activated, so that the two infrared receivers set on the frame 1 receive the infrared signals emitted by the infrared transmitter 66 to reset, thereby improving the detection accuracy of the equipment.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
