Description

Technical Field

[0001] This utility model relates to the field of wall panel load-bearing strength testing technology, and more specifically, to a device for testing the load-bearing strength of concrete wall panels. Background Technology

[0002] As the main load-bearing or enclosure components of a building structure, concrete wall panels directly affect the safety, durability, and functionality of the building. With the increasing demands for quality, energy conservation, and earthquake resistance in the construction industry, testing technology for concrete wall panels is constantly developing to ensure that they meet design specifications and construction standards.

[0003] Currently, the load-bearing capacity of wall panels is tested by drilling holes in the wall panel, installing expansion bolts, and then suspending a load on the bolts. However, because the load has a certain thickness, the suspension rope will tilt. When the wall panel cannot bear the weight of the load, the suspension rope will generate a certain lateral force with the bolts, causing it to swing significantly. In addition, the existing loads need to be lifted and suspended by hand by workers. When releasing the load, the load is close to the suspension point, which poses a certain safety hazard and is also quite laborious. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a concrete wall panel load-bearing strength testing device to solve the problems that the existing wall panel load-bearing strength testing methods have certain safety hazards and are relatively laborious.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a concrete wall panel load-bearing strength testing device, including a fixed base, a fixing component on the fixed base, the wall panel to be tested can be vertically fixed in the fixed base by the fixing component, a vertical slide is provided on the fixing component, a protective cover is vertically slidably connected to the vertical slide, a lifting component for raising or lowering the protective cover is also provided on the vertical slide, two parallel suspension rollers are rotatably connected to the center of the front of the protective cover, and slots are opened on both sides of the protective cover along its length.

[0006] Preferably, the fixing assembly includes two clamping frames, each with a limiting slide rod. The limiting slide rod is slidably inserted into a fixed base. A counter-rotating threaded rod is rotatably connected inside the fixed base. A threaded tube is fixedly connected to the bottom of each of the two clamping frames. The outer surface of the threaded tube is movably inserted into the fixed base, and the two threaded tubes are respectively threaded to both ends of the counter-rotating threaded rod. A driven gear is fixedly installed in the middle of the counter-rotating threaded rod. A first motor is fixedly installed inside the fixed base. A driving gear is fixedly installed at the output end of the first motor. The driven gear meshes with the driving gear. The vertical slide is fixedly installed on the clamping frames.

[0007] Preferably, the clamping plate frame has an H-shaped structure, and two clamping plate frames are symmetrically arranged on the fixed base.

[0008] Preferably, the lifting assembly includes a second motor, which is fixedly installed on the top of the vertical slide. A one-way threaded rod is rotatably connected between the vertical slide and the clamping frame. The output end of the second motor is fixedly connected to the top end of the one-way threaded rod. A threaded tube is fixedly installed on the top of the protective cover, and the inner surface of the threaded tube is threadedly connected to the outer surface of the one-way threaded rod.

[0009] Preferably, a plurality of transmission rollers arranged in a row are rotatably disposed inside the fixed base, and the arrangement direction of the transmission rollers is consistent with the moving direction of the clamping frame.

[0010] Preferably, the outer side of the protective cover is provided with a plurality of evenly distributed mesh holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention involves inserting a load-bearing rope between two suspension rollers through a slot, with the other end of the rope secured to a bolt. At this point, the load is on the ground and the rope is slack. Then, the protective cover is automatically lifted by a lifting assembly, causing the suspension rollers to suspend the load in the air. When the wall panel under test suddenly breaks, the suspension rollers cause the rope to swing upwards, allowing the rope, along with the bolt and concrete fragments, to splash onto the protective cover and be intercepted. This greatly reduces the danger caused by wall breakage during the testing process, and eliminates the need for manual load handling, making the operation simple and labor-saving.

[0013] This invention uses a first motor to drive the active gear to mesh with the driven gear, which causes the two threaded tubes of the opposite-direction threaded rod to move in close proximity. This, in turn, drives the clamping frame to vertically clamp and fix the wall panel to be tested, thus ensuring the stability of the wall.

[0014] This invention uses a second motor to drive a unidirectional threaded rod to rotate, which in turn drives the threaded tube to automatically raise and lower the protective cover vertically along the surface of the vertical slide. The second motor can be remotely controlled by a controller, thus keeping the staff further away from the inspection position during the lifting process and further ensuring the safety of the inspection process.

[0024] Specifically, the wall panel 3 to be tested is fixed to the base 1 by the fixing component 2. Then, holes are drilled in the area covered by the protective cover 5 on the wall panel 3 and bolts are installed. The suspension rope with the load is then inserted between the two suspension rollers 7 through the slot 8, and the other end of the suspension rope is tied to the bolt. At this time, the load is on the ground and the suspension rope is slack. Then, the protective cover 5 is lifted by the lifting component 6, so that the suspension rollers 7 lift the load and keep the bolt and suspension rope within the coverage area of ​​the protective cover 5. When the wall panel 3 to be tested is suddenly damaged, the suspension rollers 7 can make the suspension rope swing upward, so that the suspension rope, along with the bolt and concrete fragments, splashes onto the protective cover 5 and is intercepted and blocked.

[0025] Preferably, the fixing assembly 2 includes two clamping frames 21, each of which is provided with a limiting slide rod 22. The limiting slide rod 22 is slidably inserted into the fixing base 1. A counter-threaded rod 23 is rotatably connected inside the fixing base 1. A threaded tube 24 is fixedly connected to the bottom of each of the two clamping frames 21. The outer surface of the threaded tube 24 is movably inserted into the fixing base 1, and the two threaded tubes 24 are respectively threaded to both ends of the counter-threaded rod 23. A driven gear 25 is fixedly installed in the middle of the counter-threaded rod 23. A first motor 26 is fixedly installed inside the fixing base 1. A driving gear 27 is fixedly installed at the output end of the first motor 26. The driven gear 25 meshes with the driving gear 27. The vertical slide 4 is fixedly installed on the clamping frame 21.

[0026] The first motor 26 drives the active gear 27 to mesh with the driven gear 25 to rotate, which can cause the two threaded tubes 24 to move close or far apart through the threaded rod 23, thereby driving the clamping frame 21 to vertically clamp and fix the wall panel 3 to be tested.

[0027] Preferably, the clamping frame 21 has an H-shaped structure, and two clamping frames 21 are symmetrically arranged on the fixed base 1.

[0028] Preferably, the lifting assembly 6 includes a second motor 61, which is fixedly installed on the top of the vertical slide 4.

A threaded tube 63 is fixedly installed on the top of the protective cover 5, and the inner surface of the threaded tube 63 is threadedly connected to the outer surface of the one-way threaded rod 62.

[0029] The second motor 61 drives the one-way threaded rod 62 to rotate, which in turn drives the threaded tube 63 to lift the protective cover 5 vertically along the surface of the vertical slide 4. The second motor 61 can be remotely controlled by the controller, so that the staff can be kept away from the inspection position during the lifting process to ensure the safety of the inspection process.

[0030] Preferably, a plurality of transmission rollers 9 arranged in a row are rotatably arranged inside the fixed base 1. The arrangement direction of the transmission rollers 9 is consistent with the moving direction of the clamping frame 21, so that when the clamping frame 21 clamps and fixes the wall panel 3 to be tested, the wall panel 3 to be tested moves by the rolling of the transmission rollers 9, thereby reducing the wear on the bottom of the wall panel 3 to be tested.

[0031] Preferably, the outer side of the protective cover 5 is provided with a plurality of evenly distributed mesh holes 10 so that the staff can see the inside of the protective cover 5, thereby making it convenient for the staff to drill holes and install bolts on the wall panel 3 under test when the wall panel 3 under test is fixed and the protective cover 5 is close to the wall surface of the wall panel 3 under test.
