Description

Technical Field

[0001] This application belongs to the field of concrete construction technology and relates to tools used for handling concrete test blocks when testing concrete test blocks in a laboratory. Background Technology

[0002] During the pouring of concrete for the main building structure, regulations require the retention of a certain number of concrete test blocks for testing. The quality of the concrete construction is reflected by parameters such as the molding quality and strength of the concrete test blocks. The concrete test blocks need to be cured under specific conditions, and after curing, they are transported to the laboratory for testing.

[0003] Currently, when handling test blocks, workers typically use a handheld gripper to hold and lift them. Maintaining constant clamping force is laborious, and only one block can be handled at a time. As the project progresses, the number of concrete test blocks increases, making the handling of test blocks arduous and inefficient. Furthermore, test blocks are usually tested in groups of three, and handling them individually easily leads to confusion between different groups. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a portable test block handling tool that reduces the labor intensity of workers and improves the efficiency of test block handling.

[0005] The technical solution of this utility model is as follows:

[0006] A portable test block handling tool is characterized by comprising a support plate, wherein four rollers are provided at the bottom of the support plate near the four corners, a handle is welded to the middle of the rear end of the support plate, the handle is at a certain angle to the top surface of the support plate, two vertical rods are welded to the top surface of the support plate near the handle, the upper ends of the two vertical rods are rotatably connected to the rear end of a connecting rod by a pin, and the front end of the connecting rod is welded to the middle of the top edge of a limiting plate.

[0007] This utility model has a simple structure, is lightweight, and is easy to move and carry. It can be dragged or carried by hand to transport test blocks, and can transport a group of three test blocks at a time, thereby improving the efficiency of test block transportation and reducing the labor intensity of workers.

[0009] Figure 2 This is a plan view of the present invention;

[0010] Figure 3 This is a diagram showing the usage status when using a portable device. Detailed Implementation

[0011] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model includes a support plate 1, with four rollers 2 arranged near the four corners of the bottom of the support plate. A handle 3 is welded to the middle of the rear end of the support plate. The handle is at a certain angle to the top surface of the support plate. Two vertical rods 4 are welded to the top surface of the support plate near the handle. The upper ends of the two vertical rods 4 are rotatably connected to the rear end of a connecting rod 5 through a pin 6. The front end of the connecting rod 5 is welded to the middle of the top edge of a limiting plate 7.

[0012] In the above structure, the support plate 1 is used to place test blocks. The size of the support plate can be set so that three test blocks can be placed side by side on its top surface at one time, which facilitates the transport of a group of test blocks to the experimental position. The handle 3 is used to drag or lift the support plate, and the limiting plate 7 is used to limit the test blocks on the support plate to prevent them from falling off the support plate. The roller 2 can be a caster wheel.

[0013] In a specific implementation of this utility model, to facilitate handle installation, the rear end of the support plate 1 can be bent upward at a certain angle, and the lower end of the handle is welded to the middle of the top edge of the upwardly bent portion of the support plate.

[0014] The angle between the upwardly curved portion of the support plate and the bottom surface of the support plate shall not exceed 90 degrees.

[0015] The connecting rod 5 can adopt a sleeve-type telescopic structure, including a fixed section 51 and a movable section 52. The fixed section is a sleeve, and its rear end is connected to the upper ends of the two vertical rods by a pin. The front end of the fixed section has a through-hole screw hole. The rear end of the movable section is inserted into the front end of the fixed section. The rear end of the movable section has multiple screw holes distributed longitudinally. One screw hole at the rear end of the movable section is through-hole with the screw hole at the front end of the fixed section and fixed by a bolt 53. The front end of the movable section is welded to the limiting plate. When it is necessary to adjust the length of the connecting rod, the length of the movable section inserted into the fixed section can be adjusted, and a suitable screw hole on the movable section can be selected to connect with the fixed section.

[0016] The handle 3 can also adopt a telescopic structure similar to the connecting rod, and the length of the handle can be adjusted according to the needs and usage habits of the staff.

[0017] This utility model can be used in two ways, one of which is to adopt... Figure 1 As shown, one to three test blocks 8 are placed on the support plate 1, and workers move the test blocks by pulling them with a handle, which can reduce the labor intensity of the workers; another method is as follows... Figure 3 As shown, since the test block is transported back and forth in the outdoor laboratory, when passing steps or thresholds, the entire device and test block can be lifted by holding the handle 3. When lifting, the limiting plate 7 can prevent the test block 8 from falling off the support plate 1.
