Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete block handling tool. Background Technology

[0002] Concrete blocks are a type of artificial stone made by mixing cement, coarse aggregate (crushed stone or pebbles), fine aggregate (sand), admixtures, and water, and then hardening the mixture. They offer advantages such as high strength, light weight, ease of installation, good wall surface smoothness, and high construction efficiency. During construction, workers need to transport the concrete blocks to the construction site.

[0003] Chinese utility model patent CN210195287U discloses a concrete block clamping fixture, including an inner clamping plate and an outer clamping plate. The outer clamping plate has a through hole in the middle for the inner clamping plate, through which the inner clamping plate passes. The inner and outer clamping plates are movably connected by a pivot. Both the inner and outer clamping plates have handle holes at their tops, and support plates are fixed to their bottoms. The support plates of both the inner and outer clamping plates have corresponding wedge-shaped serrated protrusions. This concrete block clamping fixture can quickly lift and fix concrete blocks.

[0004] When construction workers use the concrete block clamp disclosed in the above-mentioned utility model patent to move concrete blocks, their hands need to be inserted into two handle holes respectively and continuously apply force to the inner clamping plate and the outer clamping plate to keep the concrete block clamped. This consumes a lot of physical strength. Moreover, if the construction workers are too weak to move the concrete blocks, they will loosen the inner or outer clamping plate and the concrete blocks will fall off the concrete block clamp, causing damage to the concrete blocks or even injury to the construction workers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete block handling tool that solves the problem that existing concrete block clamps require construction workers to continuously apply force to clamp the concrete blocks.

[0006] According to an embodiment of this utility model, a concrete block handling tool includes a frame and a handle mounted on the frame. Fixed clamps and a control box are respectively provided at both ends of the frame. The control box is provided with a movable clamp, a movable handle, a rotating component, and a first spring. The movable clamp and the movable handle are movably mounted on the control box. The movable clamp is located on the side of the control box closest to the fixed clamp and is opposite to the fixed clamp. A first groove is provided on the movable clamp. The movable handle is located on the side of the control box away from the fixed clamp and has a second groove. The middle part of the rotating component is rotatably connected to the control box, and one end of the rotating component extends into the first groove and abuts against the movable clamp, while the other end extends into the second groove and abuts against the movable handle. When the movable handle moves, it drives the rotating component to rotate and pushes the movable clamp to move in the opposite direction. The first spring is located between the movable clamp and the movable handle and drives the movable clamp and the movable handle to move away from each other.

[0007] Furthermore, the control box includes an upper housing fixedly connected to the frame and a lower housing detachably connected to the upper housing. The upper housing and the lower housing form a receiving groove. The rotating member and the first spring are respectively disposed in the receiving groove, and part of the movable clamp and part of the movable handle are received in the receiving groove.

[0008] Furthermore, the receiving groove is provided with a guide hole, the axial direction of which is consistent with the moving direction of the movable handle, and the movable handle is provided with a guide rod that cooperates with the guide hole.

[0009] Furthermore, a second spring is provided in the receiving groove, the second spring abutting against the movable handle and driving the movable handle away from the movable clamp.

[0010] Furthermore, the upper housing is provided with a plurality of first threaded holes spaced apart, and the lower housing is provided with through holes that are aligned one by one with the first threaded holes.

[0011] Furthermore, a vertical plate is provided on the side of the lower housing away from the upper housing, and the vertical plate is positioned close to the movable handle.

[0012] Furthermore, the frame includes a first rod and a second rod, the first rod is provided with a connecting rod and the second rod is provided with a slot that cooperates with the connecting rod, the fixing clamp is provided on the first rod and the control box is provided on the second rod.

[0013] Furthermore, the second rod body is provided with an elongated hole communicating with the slot, and the length direction of the elongated hole is consistent with the length direction of the connecting rod. The first rod body is provided with a second threaded hole and a locking bolt that cooperates with the second threaded hole. The locking bolt passes through the elongated hole and abuts against the second rod body.

[0014] Furthermore, the sides of the fixed clamp and the movable clamp that are close to each other are respectively covered with anti-slip plates, and the anti-slip plates are provided with protruding tooth-shaped parts.

[0015] Furthermore, the frame is also provided with a flexible pad that wraps around the handle.

[0016] Compared with existing technologies, this utility model has the following advantages: By using fixed and movable clamps on the frame to clamp the concrete block, when clamping the concrete block, pressing the movable handle causes the rotating part to rotate under the push of the movable handle, which in turn moves the movable clamp closer to the movable handle. At this time, the movable clamp moves away from the fixed clamp, increasing the gap between the movable clamp and the fixed clamp, while the first spring is further compressed. After pressing the movable handle to move the movable clamp away from the fixed clamp, the concrete block can be placed between the movable clamp and the fixed clamp. After the movable clamp and the fixed clamp are respectively located on both sides of the concrete block, they are released. The movable handle is activated, at which point the first spring returns to its original length and pushes the movable clamping plate and the movable handle away from each other until the movable clamping plate and the fixed clamping plate respectively abut against the opposite sides of the concrete block. The elastic force provided by the first spring clamps the concrete block between the movable clamping plate and the fixed clamping plate. At this point, the construction worker can hold the handle and move the concrete block to the construction site. This solves the technical problem that existing concrete block clamps require the construction worker to continuously apply force to clamp the concrete block. It achieves the technical effect of clamping the concrete block with the elastic force provided by the first spring, thereby saving manpower and preventing the concrete block from falling during transportation. Moreover, it is simple to operate and convenient to use. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a concrete block handling tool for clamping and handling concrete blocks.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 The concrete block handling tool includes a frame 1 and a handle 2 mounted on the frame 1. Fixed clamping plates 3 and a control box 4 are respectively provided at both ends of the frame 1. The control box 4 is provided with a movable clamping plate 5, a movable handle 6, a rotating component 41, and a first spring 42. The movable clamping plate 5 and the movable handle 6 are movably mounted on the control box 4. The movable clamping plate 5 is located on the side of the control box 4 closest to the fixed clamping plate 3 and is opposite to the fixed clamping plate 3. The movable clamping plate 5 has a first groove 51. The movable handle 6 is located on the side of the control box 4 away from the fixed clamping plate 3 and has a second groove 61. The middle part of the rotating component 41 is rotatably connected to the control box 4, and one end of the rotating component 41 extends into the first groove. The other end of the handle abuts against the movable clamping plate 5 inside the groove 51, and extends into the second groove 61 to abut against the movable handle 6. When the movable handle 6 moves, it drives the rotating member 41 to rotate and pushes the movable clamping plate 5 to move in the opposite direction. That is, when the movable handle 6 is pressed and retracted into the control box 4, the rotating member 41 pushes the movable clamping plate 5 to retract into the control box 4. The first spring 42 is located between the movable clamping plate 5 and the movable handle 6 and drives the movable clamping plate 5 and the movable handle 6 to move away from each other. When the movable handle 6 is pressed, the first spring 42 is further compressed. After the movable handle 6 is released, the first spring 42 returns to its original length and pushes the movable handle 6 and the movable clamping plate 5 out of the control box 4.

[0026] Specifically, the operation steps for transporting concrete blocks using the concrete block transport tool provided in this embodiment are as follows: When clamping the concrete block using the concrete block transport tool, first press the movable handle 6 to make the rotating part 41 rotate under the push of the movable handle 6 and drive the movable clamping plate 5 to move closer to the movable handle 6. At this time, the movable clamping plate 5 moves away from the fixed clamping plate 3, increasing the gap between the movable clamping plate 5 and the fixed clamping plate 3. At the same time, the first spring 42 is further compressed. After pressing the movable handle 6 to make the movable clamping plate 5 move away from the fixed clamping plate 3, the concrete block can be placed between the movable clamping plate 5 and the fixed clamping plate 3. After the movable clamping plate 5 and the fixed clamping plate 3 are respectively positioned on both sides of the concrete block, the movable handle 6 is released. At this time, the first spring 42 returns to its original length and pushes the movable clamping plate 5 and the movable handle 6 away from each other until the movable clamping plate 5 and the fixed clamping plate 3 respectively abut against the opposite sides of the concrete block. The elastic force provided by the first spring 42 clamps the concrete block between the movable clamping plate 5 and the fixed clamping plate 3. At this time, the construction worker can use the handle 2 to carry the concrete block to the construction site. After the concrete block is carried to the target position, pressing the movable handle 6 again will move the movable clamping plate 5 away from the fixed clamping plate 3, thus detaching the concrete block from the concrete block carrying tool. The concrete block carrying tool provided in this embodiment clamps the concrete block with the elastic force provided by the first spring 42. During the carrying process, the construction worker does not need to apply continuous force, thereby saving manpower and preventing the concrete block from loosening due to the construction worker's physical exhaustion. Furthermore, the operation of clamping and releasing the concrete block by the concrete block carrying tool is simple and convenient to use.

[0027] Please combine Figure 3 , Figure 4 and Figure 5 The control box 4 includes an upper housing 43 fixedly connected to the frame 1 and a lower housing 44 detachably connected to the upper housing 43. The upper housing 43 and the lower housing 44 form a receiving groove 45. The rotating component 41 and the first spring 42 are respectively disposed in the receiving groove 45, and part of the movable clamping plate 5 and part of the movable handle 6 are received in the receiving groove 45. The control box 4 is composed of the upper housing 43 and the lower housing 44 detachably connected to the upper housing 43. The upper housing 43 is fixedly connected to the frame 1, and the lower housing 44 is installed on the upper housing 43 to form the receiving groove 45 for the installation of the movable clamping plate 5, the movable handle 6, the rotating component 41 and the first spring 42, which facilitates the assembly of the concrete block handling tool.

[0028] like Figure 4and Figure 5 As shown, the receiving groove 45 is provided with a guide hole 46. The axial direction of the guide hole 46 is consistent with the moving direction of the movable handle 6, and the movable handle 6 is provided with a guide rod 62 that cooperates with the guide hole 46. By providing the guide hole 46 in the receiving groove 45 and the guide rod 62 that cooperates with the guide hole 46 on the movable handle 6, the guide rod 62 slides within the guide hole 46 as the movable handle 6 moves on the control box 4, preventing the movable handle 6 from deviating from the preset direction during movement, thereby improving the stability of the movable handle 6 during movement.

[0029] In detail, a second spring 47 is provided in the receiving groove 45. The second spring 47 abuts against the movable handle 6 and drives the movable handle 6 away from the movable clamping plate 5. With the second spring 47 abutting against the movable handle 6 in the receiving groove 45, when the movable handle 6 is pressed and retracted into the control box 4, the second spring 47 is further compressed. After the movable handle 6 is released, the second spring 47 returns to its original length, and the elastic force provided by the second spring 47 drives the movable handle 6 out of the control box 4. This ensures that the movable handle 6 moves quickly away from the movable clamping plate 5 after release, and the elastic force provided by the second spring 47 keeps the movable handle 6 abutting against the inner wall of the receiving groove 45 after release. This prevents the movable clamping plate 5 from moving unexpectedly when the concrete block handling tool is used to handle concrete blocks, thus avoiding loosening of the movable clamping plate 5.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the upper housing 43 is provided with a plurality of first threaded holes spaced apart, and the lower housing 44 is provided with through holes 48 aligned with the first threaded holes one by one. By using screws or other connecting parts passing through the through holes 48 and engaging with the first threaded holes, the lower housing 44 can be fixed to the upper housing 43, ensuring a secure connection between the two and improving the structural stability of the concrete block handling tool.

[0031] In this embodiment, a vertical plate 49 is provided on the side of the lower housing 44 away from the upper housing 43, and the vertical plate 49 is located near the movable handle 6. The vertical plate 49 on the lower housing 44 is used to facilitate the construction personnel to press the movable handle 6. When the construction personnel operate the concrete block handling tool, they can move the movable handle 6 on the control box 4 by holding the vertical plate 49 with their fingers and pressing the movable handle 6 with their palm, thereby facilitating the operation of the concrete block handling tool.

[0032] Please combine Figure 1and Figure 2 The frame 1 includes a first rod 11 and a second rod 12. The first rod 11 has a connecting rod 13, and the second rod 12 has a slot 14 that mates with the connecting rod 13. A fixed clamp 3 is mounted on the first rod 11, and a control box 4 is mounted on the second rod 12. The frame 1 is composed of the first rod 11 and the second rod 12, which are slidably connected. The distance between the fixed clamp 3 and the movable clamp 5 can be adjusted by sliding the connecting rod 13 within the slot 14, allowing the distance to be adapted to the size of the concrete block. This enables the concrete block handling tool to handle various sizes of concrete blocks, improving its versatility.

[0033] Specifically, the second rod 12 has an elongated hole 15 communicating with the slot 14, and the length direction of the elongated hole 15 is consistent with the length direction of the connecting rod 13. The first rod 11 has a second threaded hole and a locking bolt 16 that mates with the second threaded hole. The locking bolt 16 passes through the elongated hole 15 and abuts against the second rod 12. When the connecting rod 13 slides in the slot 14, the locking bolt 16 slides in the elongated hole 15 along with the movement of the connecting rod 13. After the connecting rod 13 is adjusted to the correct position, tightening the locking bolt 16 so that it abuts against the second rod 12 locks the relative position of the first rod 11 and the second rod 12, preventing the first rod 11 from loosening during the use of the concrete block handling tool. Further adjustment is needed to loosen the locking bolt 16, making the operation simple.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The fixed clamping plate 3 and the movable clamping plate 5 are respectively covered with anti-slip plates 7 on their adjacent sides, and the anti-slip plates 7 are provided with protruding toothed portions 71. By providing anti-slip plates 7 on the fixed clamping plate 3 and the movable clamping plate 5 respectively, the anti-slip plates 7 are in direct contact with the concrete blocks when the fixed clamping plate 3 and the movable clamping plate 5 clamp the concrete blocks. The protruding toothed portions 71 on the anti-slip plates 7 can increase the friction between the anti-slip plates 7 and the concrete blocks, ensuring that the concrete blocks remain stable on the concrete block handling tool after being clamped, and preventing the concrete blocks from slipping between the fixed clamping plate 3 and the movable clamping plate 5.

[0035] In detail, the frame 1 is also provided with a flexible pad 21, which wraps around the handle 2. The flexible pad 21 wrapping around the handle 2 is used to improve the comfort of the handle 2. The flexible pad 21 is made of soft materials such as silicone, rubber or foam, reducing the discomfort caused by the handle 2 pressing on the hands of construction workers when using the concrete block handling tool to carry concrete blocks.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
