Description

Technical Field

[0001] This application relates to the technical field of concrete testing, and in particular to a device for assisting in moving and flipping concrete test molds. Background Technology

[0002] In the process of concrete engineering construction and quality testing, concrete molds are often used to make test blocks for subsequent strength testing and other purposes.

[0003] After pouring, the test molds need to be moved to the curing area, and often need to be turned over before demolding. However, because concrete test molds are small in volume, large in weight, and numerous when filled with concrete, the operation is quite cumbersome and laborious. Current practices usually require workers to bend over and lift the test molds or turn them over, which not only increases the workload but also causes considerable damage to the workers' bodies, especially their lower backs, due to the repetitive nature of these actions over a long period of time.

[0004] Therefore, there is an urgent need for a device that can assist in moving and flipping concrete test molds to reduce the burden on workers, improve work efficiency, and reduce physical harm. Utility Model Content

[0005] To facilitate the movement and flipping of concrete test molds, this application provides a device for assisting in the movement and flipping of concrete test molds.

[0006] This application provides a device for assisting in moving and flipping concrete test molds, which adopts the following technical solution:

[0007] A device for assisting in moving and flipping a concrete test mold includes a handle, a fixing nail at the lower end of the handle, and a hook rotatably mounted on the handle. The fixing nail and the hook can be hooked onto both sides of the raised edge of the concrete test mold, and the device also includes an elastic element that drives the hook and the fixing nail to move closer together and fasten the concrete test mold.

[0008] By adopting the above technical solution, the isomorphic hooks engage with the raised edge of the concrete mold, making it easy to flip the concrete mold. Furthermore, the fixing nails and hooks work together to hook onto both sides of the raised edge of the concrete mold, and with the help of the elastic element, the mold can be stably fixed, thereby allowing the mold to be moved by the handle.

[0009] Optionally, two hooks are rotatably mounted on the handle and are located on both sides of the handle respectively.

[0010] By adopting the above technical solution, the contact area between the device and the test mold can be increased, thereby improving stability.

[0011] Optionally, the two hooks are provided with positioning plates, and the elastic element is a locking spring provided between the positioning plate and the handle. When the hooks and the fixing nails are respectively hooked on the concrete test mold protrusion, the locking spring is in a stretched state.

[0012] By adopting the above technical solution, the introduction of the positioning plate and locking spring further ensures a stable connection between the hook and the fixing pin. When the hook and the fixing pin are respectively hooked onto the protruding edge of the mold, the locking spring is stretched, generating a certain tension, making the connection between the device and the mold more tight.

[0013] Optionally, it also includes a positioning block for positioning the fixing nail. The positioning block is disposed on the hook claw and has a positioning groove. When the hook claw rotates toward the handle, the fixing nail is engaged in the positioning groove.

[0014] By adopting the above technical solution, the design of the positioning block and positioning groove enables the fixing pin to be engaged when the hook claw rotates towards the handle, thereby enhancing the stability of the operation process when flipping the mold through the hook claw.

[0015] Optionally, the upper end of the handle is provided with a non-slip sleeve for easy gripping.

[0016] By adopting the above technical solution, the anti-slip sleeve increases the grip friction of the handle, making the user more comfortable and stable during operation.

[0017] Optionally, the handle is a telescopic structure and also includes a fixing member for limiting the extension and retraction of the handle.

[0018] By adopting the above technical solution, the handle is designed with a telescopic structure, which allows the device to adapt to operators of different heights.

[0019] Optionally, the handle includes a first rod and a second rod, with the fixing pin and the hook both located at the lower end of the first rod, and the lower end of the second rod slidingly inserted into the first rod.

[0020] The fixing component includes a fixing post and a fixing spring. The second rod has a second hole for the fixing post to pass through, and the first rod has a first hole for the fixing post to pass through. Multiple first holes are spaced apart along the extension direction of the first rod. When the fixing spring is in its natural state, the end of the fixing post passes through the first hole.

[0021] By adopting the above technical solution, the fixing component restricts the extension and retraction of the handle through a fixing post and a fixing spring. Multiple first holes are spaced apart on the first rod, allowing the user to adjust the handle length as needed. This design ensures both the stability of the device and increases its flexibility of use.

[0022] Optionally, a guide block is provided on the outer side wall of the second rod, and a guide groove is provided on the inner side wall of the first rod for the guide block to slide up and down.

[0023] By adopting the above technical solution, the guide block and guide groove make the second rod slide more smoothly and accurately when sliding up and down, while restricting the rotation of the second rod relative to the first rod, making it convenient for the fixing column to pass through the first hole and the second hole.

[0024] In summary, this application includes at least one of the following beneficial effects:

[0025] 1. The handle is equipped with hooks and fixing nails that engage with the raised edge of the concrete test mold to flip or move the test mold without bending over, making it easy to operate;

[0026] 2. The retractable handle can accommodate users of different heights, further improving the comfort of operation. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] Example 1

[0035] This application discloses a device for assisting in moving and flipping a concrete test mold. (Refer to...) Figure 1 and Figure 2The device for assisting in moving and flipping the concrete test mold includes a handle 1, a fixing nail 2, a hook 3, and an elastic element 4. The handle 1 is a long, round rod. The fixing nail 2 is located at the lower end of the handle 1 and can be fixed to the side wall of the handle 1 by welding or bolts. The hook 3 is rotatably located at the lower end of the handle 1 and has a hook facing one end of the handle 1. The concrete test mold 101 is a rectangular frame with a hollow interior and an open top. Both the upper and lower ends of the outer wall of the concrete test mold 101 are integrally formed with protruding edges. In use, the hook 3 and the fixing nail 2 can be hooked onto the protruding edges, that is, they can be abutted against the lower surface of the protruding edges on both sides of the concrete test mold 101. At this time, the elastic element 4 can drive the fixing nail 2 and the hook 3 to move closer to each other, thereby locking the protruding edges. The concrete test mold 101 can then be lifted by arm to facilitate its movement.

[0036] Reference Figure 1 and Figure 2 In this embodiment, two hooks 3 are rotatably mounted on the handle 1 and are located on both sides of the handle 1, thereby increasing the stability when moving the concrete mold 101. Positioning plates 5 are provided on the two hooks 3. Each hook 3 includes a hook body connected to the handle 1 and a bent hook portion for hooking the concrete mold 101. The positioning plates 5 are fixed to the bent hook portions of the hooks 3, and the hook bodies of both hooks 3 pass through the positioning plates 5, thereby improving the stability of the two hooks 3.

[0037] In this embodiment, the positioning plate 5 can have a rectangular cross-section, and the hooks 3 can be fixed to the positioning plate 5 by welding. In other embodiments, the positioning plate 5 can have a rectangular ring structure, and both hooks 3 can pass through the inside of the positioning plate 5 and be fixed to the inner sidewall of the positioning plate 5. The elastic element 4 is a locking spring 41. One end of the locking spring 41 is fixed to the sidewall of the positioning plate 5, and the other end of the locking spring 41 is connected to the sidewall of the handle 1. The locking spring 41 is connected below the connection point of the hooks 3. When the fixing nail 2 and the hooks 3 are hooked to both sides of the concrete mold 101, the locking spring 41 is in a stretched state, thereby providing elastic force to bring the fixing nail 2 and the hooks 3 closer together to fasten the concrete mold 101.

[0038] Reference Figure 2 and Figure 3Optionally, the device for assisting in moving and flipping the concrete mold can also include a positioning block 6, which is fixed to two hooks 3. The upper surface of the positioning block 6 has a positioning groove, and the positioning block 6 is preferably made of elastic materials such as plastic or rubber. Thus, when the hooks 3 rotate towards the handle 1, force can be applied to engage the fixing pin 2 into the positioning groove. The friction between the positioning block 6 and the fixing pin 2 can restrict the rotation of the hooks 3, thereby positioning them. At this time, by hooking the hooks 3 onto the lower surface of the raised edge of the concrete mold 101 and applying force, the concrete mold 101 can be easily flipped.

[0039] When it is necessary to rotate the hook 3, one side of the hook 3 can be placed on the concrete mold 101, and then the handle 1 can be rotated to disengage the fixing nail 2 from the positioning groove. The hook 3 can then be used to clamp the concrete mold 101 with the fixing nail 2.

[0040] Reference Figure 1 and Figure 3 Alternatively, an anti-slip sleeve 7 can be fixed to the upper end of the handle 1. The anti-slip sleeve 7 is preferably made of rubber, and anti-slip texture is provided on the outer side wall of the anti-slip sleeve 7, so as to facilitate gripping the handle 1 and controlling the handle 1.

[0041] The implementation principle of the device for assisting in moving and flipping a concrete test mold according to an embodiment of this application is as follows: when the hook 3 is engaged with one side of the concrete test mold 101, the concrete test mold 101 can be flipped by applying force with the arm; when the hook 3 and the fixing nail 2 are respectively engaged with the two sides of the protruding edge of the concrete test mold 101, they are locked by the locking spring 41, and the concrete test mold 101 can be moved by lifting it upward with the handle 1.

[0042] Example 2:

[0043] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the length of the handle 1 is adjustable. (Refer to...) Figure 4 Specifically, the handle 1 includes a first rod 11 and a second rod 12 that slides up and down on the first rod 11. Both the first rod 11 and the second rod 12 are round rods. The hook 3 and the fixing pin 2 are both located at the lower end of the first rod 11. The upper end of the first rod 11 is provided with a groove for the second rod 12 to slide up and down. A fixing member 8 is also provided between the first rod 11 and the second rod 12 to limit the sliding of the second rod 12.

[0044] Reference Figure 4 and Figure 5In this embodiment, the fixing member 8 includes a fixing post 81 and a fixing spring 82. The fixing post 81 is slidably disposed within the second rod 12 along the horizontal direction. One end of the fixing spring 82 is fixed to the inner side wall of the second rod 12, and the other end is connected to the bottom wall of the fixing post 81. The fixing post 81 is cylindrical, and the end of the fixing post 81 facing away from the fixing spring 82 is preferably rounded. The fixing post 81 can slide along its own direction through the second rod 12 and the first rod 11 under the action of the spring. Correspondingly, the second rod 12 has a second hole 121 for the fixing post 81 to pass through. A first hole 111 is provided on a rod 11 for a fixing post 81 to pass through. Multiple first holes 111 are provided at intervals along the length of the first rod 11. When the end of the fixing post 81 passes through the second hole 121 and the first hole 111 in sequence, the post body is engaged with the first hole 111, thereby restricting the sliding of the second rod 12. In use, press the fixing post 81, and the second rod 12 can be slid up and down. When the handle 1 is adjusted to the appropriate length, release the fixing post 81. Under the action of the fixing spring 82, the fixing post 81 passes through the corresponding first hole 111, and the length of the handle 1 can be adjusted.

[0045] Furthermore, a guide block 122 can be welded to the outer wall of the second rod 12. The guide opening is preferably a rectangular block and can be symmetrically arranged on the side wall of the first rod 11. A guide groove 112 is provided on the inner wall of the first rod 11 for the guide block 122 to slide up and down. Through the cooperation of the guide block 122 and the guide groove 112, the up and down sliding of the second rod 12 can be made more stable, and the rotation of the second rod 12 relative to the first rod 11 can be restricted.

[0046] The implementation principle of the device for assisting in moving and flipping a concrete test mold according to the embodiment of this application is as follows: Before use, according to the user's height, press the fixed column 81, adjust the handle 1 to a suitable length, and then release the fixed column 81. The concrete test mold 101 can then be moved or flipped by controlling the handle 1.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
