Description
Technical Field
[0001] This utility model relates to the field of brick transportation technology, specifically a clamp for transporting masonry bricks. Background Technology
[0002] In construction engineering, masonry bricks are widely used in the construction of various structures, such as roads, walls, and landscaping. Masonry bricks are typically composed of stones or bricks of different materials, shapes, and sizes to meet diverse engineering needs. Because construction site roads are often long, these bricks need to be transported and placed during construction to ensure construction quality and structural stability. Construction sites primarily rely on manual labor for handling, and in this process, the varying shapes and sizes of the bricks mean that traditional brick clamps cannot effectively handle multiple different shapes of bricks simultaneously during clamping and transportation.
[0003] Patent CN222158961U discloses a clamp for transporting masonry bricks, including a clamping body; two sets of driving components are arranged opposite to each other on the clamping body; a rotating rod is rotatably mounted on the clamping body; each rotating rod is provided with at least one clamping component; a moving part has a clamping portion, one end of the moving part is mounted on the rotating rod, and after the rotating rod rotates, the clamping portion moves closer to or further away from the side of the brick. This technical solution solves the problem in the prior art that it is impossible to effectively clamp multiple stones or bricks of different shapes simultaneously, requiring multiple trips for transport, which affects transport efficiency and causes high labor intensity.
[0004] While the aforementioned existing technologies improve handling efficiency to some extent, safety hazards still exist during practical use. When the lifting rod moves upward, the rotating rod rotates, causing the moving part to rotate downward, and the clamping part makes close contact with the side of the brick, thereby clamping multiple bricks. However, during handling, if other bricks are stacked on top of the middle brick, the middle brick will be subjected to a vertical force from above. If this vertical force exceeds the horizontal force applied by the clamping parts on both sides, the middle brick may fall downward during transportation, causing a safety hazard. This not only increases the risk of brick damage but may also lead to worker injury. Therefore, to address this problem, we propose a clamp for transporting masonry bricks to effectively prevent bricks from falling during handling, while enhancing the stability and safety of the clamp. Utility Model Content
[0005] The purpose of this invention is to provide a clamp for transporting masonry bricks, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A clamp for transporting masonry bricks includes a supporting base plate for supporting the bricks and providing stable support to prevent the middle bricks from falling off. Figure 1 , Figure 2 and Figure 5 As shown, movable grooves are provided on both the left and right sides of the supporting fixed base plate. The movable grooves are used for the sliding of the supporting movable plate and to accommodate the spring. The two movable grooves are slidably connected to the supporting movable plate. The supporting movable plate is used to drive the clamping side plate to move laterally to adapt to bricks of different sizes. The opposite sides of the two supporting movable plates are provided with clamping side plates. The clamping side plates are used to directly clamp the side of the brick to prevent the brick from slipping during transportation.
[0008] L-shaped connecting plates are provided on the opposite sides of the two clamping side plates and near the front and rear sides. The L-shaped connecting plates are used to connect the tie rods and transmit the clamping force. All four L-shaped connecting plates are rotatably connected to tie rods. The tie rods are used to convert the pulling force of the hoisting assembly into the clamping action of the clamping side plates. The top of the four tie rods are connected to the hoisting assembly. The hoisting assembly is used to connect to external hoisting equipment and control the lifting and lowering of the clamp. When the hoisting assembly moves upward, the four tie rods rotate adaptively, so that the two clamping side plates move relative to each other, thereby clamping and fixing the bricks placed on the supporting and fixed base plate. Under the action of the supporting and fixed base plate, the bricks in the middle can be prevented from falling downward.
[0009] The hoisting assembly includes a hoisting rod, which serves as the main structure of the hoisting assembly and transmits lifting force. Both ends of the hoisting rod are provided with connecting blocks, which are used to connect the top of the rod and enable rotation. The top of the hoisting rod is provided with two lifting rings arranged symmetrically front to back, which are used to connect external hooks or ropes and provide a hoisting force point.
[0010] Preferred, combined Figure 2 , Figure 3 and Figure 4 As shown, the movable groove is equipped with multiple springs arranged at equal intervals in the front and back. The two ends of the springs abut against the inner wall of the movable groove and the side of the supporting movable plate, respectively. When the clamp is placed on the ground to wait for the transport of masonry bricks, the springs are used to push the supporting movable plate to reset outward, so that the clamping side plate is kept in an unfolded state for loading and unloading bricks.
[0011] The inner wall of the movable groove and the side away from the supporting movable plate are provided with a plurality of first circular fixing sleeves arranged at equal intervals. The end of the spring away from the supporting movable plate is located inside the first circular fixing sleeve. The first circular fixing sleeve is used to fix one end of the spring to ensure stable reset when the spring is compressed.
[0012] The two supporting movable plates are provided with multiple second circular fixing blocks arranged at equal intervals on their opposite sides. The end of the spring away from the first circular fixing block is located inside the second circular fixing block. The second circular fixing block is used to fix the other end of the spring and cooperates with the first circular fixing block to limit the displacement of the spring.
[0013] Preferably, combining 2 and Figure 4 As shown, threaded grooves are provided on both the front and rear sides of the support movable plate. The threaded grooves are used to install anti-loosening bolts to limit the sliding range of the support movable plate. The threaded grooves are threaded with anti-loosening bolts, which are used to prevent the support movable plate from disengaging from the movable groove. The front and rear sides of the inner wall of the movable groove are provided with strip-shaped holes for the anti-loosening bolts to pass through. The strip-shaped holes are used to allow the anti-loosening bolts to slide and limit the movement stroke of the support movable plate.
[0014] Preferred, such as Figure 4 As shown, the top of the L-shaped connecting plate is provided with a first connecting groove, and the bottom end of the pull rod is rotatably connected to the first connecting groove through a pin. The first connecting groove is used to connect the bottom end of the pull rod through the pin, so as to realize the flexible rotation of the pull rod.
[0015] Preferred, such as Figure 5 As shown, the two connecting blocks are provided with second connecting slots on both the left and right sides. The top ends of the four tie rods are rotatably connected to the four second connecting slots by pins. The second connecting slots are used to connect the top ends of the tie rods by pins to realize the linkage between the hoisting component and the tie rods.
[0016] Preferred, such as Figure 1 As shown, fixed horizontal tubes are provided on the right side of the left clamping side plate and at both the front and rear sides. The fixed horizontal tubes are used to install movable horizontal bars and enhance the lateral stability of the clamping side plates on both sides. The fixed horizontal tubes are slidably connected to the movable horizontal bars. The right end of the movable horizontal bars is installed on the left side of the right clamping side plate by bolts. The movable horizontal bars, together with the fixed horizontal tubes, are used to connect the left and right clamping side plates to prevent bricks from falling from the front and rear directions.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The clamp used for transporting masonry bricks provides stable support to the bottom of the masonry bricks through the support and fixing base plate, and combined with the horizontal clamping force of the clamping side plates on both sides, it effectively prevents the middle bricks from falling downwards due to the pressure of the stacking above, and significantly reduces safety hazards during transportation.
[0019] 2. The clamp used for transporting masonry bricks has a sliding fit between the movable groove and the supporting movable plate, and an automatic reset function of the spring, which allows the clamping side plate to flexibly adjust the spacing to adapt to the clamping requirements of bricks of different sizes, greatly improving work efficiency.
[0020] 3. The clamp used for transporting masonry bricks features a sliding connection design between the fixed horizontal tube and the movable horizontal bar. During the clamping process, the clamping side plate moves, preventing the bricks from slipping off from the front and back due to shaking, thus further ensuring the stability of transportation.
[0021] 4. The clamp used for transporting masonry bricks has a lifting component that uses a linkage design between the tie rod and the clamping side plate. The clamping action can be automatically completed by simply lifting the lifting ring, without the need for manual adjustment of the clamping force, which significantly reduces manpower consumption and operational complexity.

Figure 1 , Figure 2 and Figure 5 As shown, movable grooves 10 are provided on both the left and right sides of the supporting fixed base plate 1. The movable grooves 10 are used for the sliding of the supporting movable plate 2 and to accommodate the spring 7. The two movable grooves 10 are slidably connected to the supporting movable plate 2. The supporting movable plate 2 is used to drive the clamping side plate 3 to move laterally to adapt to bricks of different sizes. The opposing sides of the two supporting movable plates 2 are provided with clamping side plates 3. The clamping side plates 3 are used to directly clamp the side of the brick to prevent the brick from slipping during transportation.
[0032] L-shaped connecting plates 4 are provided on the opposite sides of the two clamping side plates 3 and near the front and rear sides. The L-shaped connecting plates 4 are used to connect the tie rods 5 and transmit the clamping force. The tie rods 5 are rotatably connected to the four L-shaped connecting plates 4. The tie rods 5 are used to convert the pulling force of the hoisting assembly 6 into the clamping action of the clamping side plates 3. The top of the four tie rods 5 are connected to the hoisting assembly 6. The hoisting assembly 6 is used to connect the external hoisting equipment and control the lifting and lowering of the clamp. When the hoisting assembly 6 moves upward, the four tie rods 5 rotate adaptively, so that the two clamping side plates 3 move relative to each other, so that the two clamping side plates 3 clamp and fix the masonry bricks placed on the supporting and fixed base plate 1. Under the action of the supporting and fixed base plate 1, the middle masonry bricks can be prevented from falling downward.
[0033] The hoisting assembly 6 includes a hoisting rod 60, which serves as the main structure of the hoisting assembly 6 and transmits lifting force. Both ends of the hoisting rod 60 are provided with connecting blocks 61, which are used to connect the top of the tie rod 5 and enable rotation. The top of the hoisting rod 60 is provided with two lifting rings 62 arranged symmetrically in front and behind, which are used to connect external hooks or ropes and provide a hoisting force point.
[0034] In this embodiment, combined with Figure 2, Figure 3 and Figure 4 As shown, the movable groove 10 is provided with multiple springs 7 arranged at equal intervals in front and behind. The two ends of the springs 7 abut against the inner wall of the movable groove 10 and the side of the supporting movable plate 2, respectively. When the clamp is placed on the ground to wait for the transport of masonry bricks, the springs 7 are used to push the supporting movable plate 2 to reset outward, so that the clamping side plate 3 is kept in the unfolded state for loading and unloading bricks.
[0035] The inner wall of the movable groove 10 and the side away from the supporting movable plate 2 are provided with a plurality of first circular fixing sleeves 12 arranged at equal intervals. The end of the spring 7 away from the supporting movable plate 2 is located in the first circular fixing sleeve 12. The first circular fixing sleeve 12 is used to fix one end of the spring 7 to ensure that the spring 7 is stably reset when compressed.
[0036] The two supporting movable plates 2 are provided with multiple second circular fixing sleeves 20 arranged at equal intervals on opposite sides. The end of the spring 7 away from the first circular fixing sleeve 12 is located inside the second circular fixing sleeve 20. The second circular fixing sleeve 20 is used to fix the other end of the spring 7 and cooperates with the first circular fixing sleeve 12 to limit the displacement of the spring 7.
[0037] Specifically, combining 2 and Figure 4 As shown, threaded grooves 21 are provided on both the front and rear sides of the support movable plate 2. The threaded grooves 21 are used to install anti-loosening bolts 8 to limit the sliding range of the support movable plate 2. The threaded grooves 21 are threadedly connected to the anti-loosening bolts 8. The anti-loosening bolts 8 do not contact the support fixed base plate 1 to avoid affecting the movement of the support movable plate 2. The anti-loosening bolts 8 are used to prevent the support movable plate 2 from disengaging from the movable groove 10. The front and rear sides of the inner wall of the movable groove 10 are provided with strip holes 11 for the anti-loosening bolts 8 to pass through. The strip holes 11 are used to allow the anti-loosening bolts 8 to slide and limit the movement stroke of the support movable plate 2.
[0038] Furthermore, such as Figure 4 As shown, the top of the L-shaped connecting plate 4 is provided with a first connecting groove 40, and the bottom end of the pull rod 5 is rotatably connected to the first connecting groove 40 through a pin. The first connecting groove 40 is used to connect the bottom end of the pull rod 5 through the pin, so as to realize the flexible rotation of the pull rod 5.
[0039] Furthermore, such as Figure 5 As shown, the two connecting blocks 61 are provided with second connecting grooves 610 on both the left and right sides. The top ends of the four tie rods 5 are rotatably connected to the four second connecting grooves 610 through pins. The second connecting grooves 610 are used to connect the top ends of the tie rods 5 through pins to realize the linkage between the hoisting component 6 and the tie rods 5.
[0040] Furthermore, such as Figure 1As shown, fixed horizontal tubes 9 are provided on the right side of the left clamping side plate 3 and on both the front and rear sides. The fixed horizontal tubes 9 are used to install the movable horizontal bars 90 and enhance the lateral stability of the clamping side plates 3 on both sides. The fixed horizontal tubes 9 are slidably connected to the movable horizontal bars 90. The right end of the movable horizontal bars 90 is installed on the left side of the right clamping side plate 3 by bolts. The movable horizontal bars 90 and the fixed horizontal tubes 9 are used to connect the left and right clamping side plates 3 to prevent bricks from falling from the front and rear directions.
[0041] In this embodiment, the clamp for transporting masonry bricks is used by first placing the supporting base plate 1 on the ground. At this time, the spring 7 in the movable groove 10 pushes the supporting movable plate 2 to slide outward, causing the clamping side plate 3 to unfold to the maximum spacing, forming a space for loading and unloading bricks. Then, the masonry bricks are stacked on the supporting base plate 1, ensuring that the bottom of the bricks is in full contact with the supporting base plate 1. At this time, the lifting ring 62 of the lifting assembly 6 is connected to an external hook or rope to lift the lifting rod 60 upward. The lifting rod 60 drives the four tie rods 5 to rotate synchronously through the connecting block 61. The bottom end of the tie rod 5 passes through the first connecting groove 40. Hinged to the L-shaped connecting plate 4, the tension is converted into a horizontal clamping force of the clamping side plate 3, causing the two clamping side plates 3 to move towards each other and clamp the two sides of the brick; at the same time, the fixed horizontal tube 9 and the movable horizontal bar 90 automatically adjust their lengths as the clamping side plates 3 move; during transportation, the supporting fixed base plate 1 continuously supports the bottom of the brick to prevent the middle brick from falling due to stacking pressure, and the spring 7 is kept in a stable compressed state through the first circular fixed sleeve 12 and the second circular fixed sleeve 20; after transportation is completed, the hoisting rod 60 is slowly lowered, the spring 7 pushes the supporting movable plate 2 to reset, the clamping side plate 3 unfolds, and the brick can be safely unloaded.
