Description

Technical Field

[0001] This utility model relates to a construction clamping device. Background Technology

[0002] With the vigorous construction of infrastructure projects, the construction technology of slopes and drainage channels has become increasingly mature, and slope protection methods, represented by retaining wall construction technology, have been greatly developed. Retaining wall construction technology has the advantages of stabilizing roadbeds and preventing landslides, water erosion, and water flow, while also reducing costs and considering environmental aesthetics. Related retaining wall construction equipment is also becoming increasingly sophisticated. On-site retaining wall construction mainly adopts the method of manually transporting and laying stones. The stones are manually moved to the laying position, and mortar is then filled in. The stones used for on-site laying are heavy and large in volume, making manual handling time-consuming and labor-intensive, posing a significant challenge to manual scheduling. To address this issue, we propose a construction clamping device. Utility Model Content

[0003] This invention provides a construction clamping device that can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows: A construction clamping device, comprising A connecting plate, with an adjustment groove formed on the top of the connecting plate; Hanging platform; A clamping mechanism is provided at the four bottom corners of the connecting plate for clamping bricks and stones; the clamping mechanism includes a first cylinder, a telescopic rod connected to the first cylinder, a first side plate and a second side plate symmetrically arranged at the corners of the connecting plate, and a clamping member hinged between the first side plate and the second side plate. An auxiliary pressing mechanism is provided at the bottom center of the connecting plate for pressing bricks and stones; the auxiliary pressing mechanism includes a second cylinder, a fixed plate provided at the output end of the second cylinder, and an upper pressure plate provided at the bottom of the fixed plate.

[0005] The beneficial effects of this utility model are: (1) This scheme achieves flexible positioning of the overall structure by cooperating with the top adjustment groove of the connecting plate and the hanging plate. The clamping mechanism set at the four corners adopts the design of the first cylinder driving the telescopic rod to drive the hinged clamping parts, which can simultaneously control the four clamping points to achieve stable gripping of bricks and stones, ensuring uniform force and preventing them from falling off. The auxiliary pressing mechanism set in the middle applies controllable pressure to the center of the bricks and stones by driving the upper pressure plate with the second cylinder, forming a coordinated fixing effect with the surrounding clamping mechanism, effectively preventing the bricks and stones from shifting or tilting during the handling process. The overall structure achieves the organic combination of clamping and pressing functions through modular design, which not only improves the stability of brick and stone handling, but also adapts to the operation requirements of bricks and stones of different specifications, and has the beneficial effects of simple operation, accurate positioning, and safety and reliability.

[0013] Reference Figure 1-3 As shown, a construction clamping device includes... Connecting plate 10, with an adjustment groove 100 formed on the top of the connecting plate 10; hanging plate 20.

[0014] A clamping mechanism 30 is disposed at the bottom four corners of the connecting plate 10 for clamping bricks and stones. The clamping mechanism 30 includes a first cylinder 300, a telescopic rod 302 connected to the first cylinder 300, a first side plate 304 and a second side plate 306 symmetrically disposed at the corners of the connecting plate 10, and a clamping member disposed between the first side plate 304 and the second side plate 306. The clamping member includes a movable arm 310, a first connecting rod 312 disposed at one end of the movable arm 310, and the first connecting rod 312 is movably connected to a pivot plate 308 disposed at one end of the telescopic rod 302, so that the first cylinder 300... Pushing the telescopic rod 302 causes the movable arm 310 to open and close. A mounting plate 316 is provided between the two movable arms 310, and a reinforcing connecting plate 318 is provided on one side of the mounting plate 316. A second connecting rod 314 is provided between the first side plate 304 and the second side plate 306. The movable arm 310 is hinged to the second connecting rod 314, so that the movable arm 310 has a fulcrum for rotation. A crossbar 3160 is provided on one side of the mounting plate 316, and a clamping rod 3162 is provided at one end of the crossbar 3160. A receiving bent rod 3180 for placing bricks and stones is provided at the bottom of the reinforcing connecting plate 318.

[0015] Specifically, a small air nozzle (not shown in the figure) is integrated on the inner side of the 3180 bending rod to blow away the floating dust on the surface of the bricks and stones before clamping, ensuring clamping stability.

[0016] In one embodiment, an elastic rubber pad or pneumatic suction cup (not shown in the figure) is added to the end of the clamping rod 3162, which not only enhances the friction but also adapts to the unevenness of the surface of bricks of different sizes, preventing slippage during clamping.

[0017] Furthermore, a spring damper (not shown in the figure) is added at the hinge of the movable arm 310 and the second connecting rod 314 to automatically adjust the clamping force according to the weight of the bricks and stones, so as to avoid overpressure damage to the edges of the bricks and stones.

[0018] Furthermore, the clamping rod 3162 and the crossbar 3160 are detachable and connected by threads or snaps, making it easy to replace clamping heads of different shapes (such as flat head and arc shape) to adapt to irregular bricks or special materials.

[0019] An auxiliary pressing mechanism 40 is located at the bottom center of the connecting plate 10 and is used to press the bricks. The auxiliary pressing mechanism 40 includes a second cylinder 400, a fixed plate 406 located at the output end of the second cylinder 400, and an upper pressure plate 408 hinged to the bottom of the fixed plate 406. A side baffle 410 is provided on one side of the top of the upper pressure plate 408, forming a clearance groove 412 on the other side of the upper pressure plate 408. An adjusting plate 402 is provided on the top of the second cylinder 400, and a bolt 404 is used to fix the adjusting plate 402. The bolt 404 passes through the adjusting groove 100, thereby moving the adjusting plate 402 back and forth and adjusting the second cylinder 400.

[0020] In one embodiment, a pressure sensor and a buffer spring (not shown in the figure) are added between the upper pressure plate 408 and the fixed plate 406 to monitor the downward pressure in real time and dynamically adjust it through the second cylinder 400 to ensure that the pressing is uniform and does not crush the bricks. At the same time, the bolt 404 of the adjusting plate 402 is replaced with a handwheel with a scale, which, together with the scale of the adjusting groove 100, enables the precise front and rear positioning of the second cylinder 400.

[0021] Furthermore, a transverse groove can be provided on the connecting plate 10, and a transverse slide rail can be added to allow the pressing mechanism to be finely adjusted laterally to adapt to the offset of the brick center.

[0022] Furthermore, the side baffle 410 can be designed to be foldable, retracted when not in use to avoid interfering with the action of the clamping mechanism; when unfolded, it forms a limiting frame with the clearance groove 412 to prevent the bricks from shaking during transportation.

[0023] The diameter of the relief groove 412 is larger than the outer diameter of the clamping rod 3162.

[0024] This utility model also includes a construction step for clamping the bricks, the steps of which are as follows: Step 1: Equipment Inspection and Positioning Check whether the cylinders (first cylinder 300 and second cylinder 400) of the clamping mechanism 30 and the auxiliary pressing mechanism 40 are working properly, confirm that the air pressure is stable, adjust the position of the hanging plate 20 so that the connecting plate 10 is aligned with the pile of bricks to be clamped, and ensure that the four corner clamping rods 3162 of the clamping mechanism 30 can cover the edge of the bricks.

[0025] Step 2: Adjust the auxiliary pressing mechanism to position 40. Loosen the bolt 404 (or the graduated handwheel) of the adjusting plate 402, and move the second cylinder 400 back and forth along the adjusting groove 100 to align it with the center of the brick. If the center of the brick is off, the lateral position of the pressing mechanism can be finely adjusted by the lateral slide rail to ensure that the upper pressure plate 408 can be pressed down accurately.

[0026] Step 3: Clean the surface of the bricks Activate the small air nozzle of the clamping mechanism 30 to blow away the dust on the surface of the brick, ensuring that the clamping surface is clean and preventing slippage.

[0027] Step 4: Clamp the brick The first cylinder 300 is activated, pushing the telescopic rod 302. Through the pivot plate 308 and the first connecting rod 312, the movable arm 310 is driven to close inward. The movable arm 310 rotates around the hinge point of the second connecting rod 314, so that the clamping rod 3162 (with elastic rubber pad or suction cup) is tightly attached to both sides of the brick. The spring damper automatically adjusts the clamping force to prevent overpressure. The supporting bent rod 3180 supports the bottom of the brick to ensure stable load-bearing.

[0028] Step 5: Assist with pressing and fixing The second cylinder 400 is activated, driving the fixed plate 406 to press down. The upper pressure plate 408 applies pressure evenly through the buffer spring and pressure sensor to avoid crushing the bricks. The side baffle 410 unfolds to form a limiting frame, which cooperates with the clearance groove 412 to avoid the clamping rod 3162 and prevent the bricks from shaking during transportation.

[0029] Step Six: Moving and Placing The bricks are transported smoothly to the target position by the hanging plate 20. During the process, the clamping mechanism 30 and the auxiliary pressing mechanism 40 are kept in coordination and stability. After reaching the position, the second cylinder 400 retracts slowly to release the pressure of the upper pressure plate 408. Then the first cylinder 300 pulls back the telescopic rod 302, so that the clamping rod 3162 releases the bricks and the placement is completed.

[0030] Step 7: Reset and Adjust (Optional) If the brick size needs to be changed, the clamping rod 3162 can be quickly disassembled and a suitable clamping head (such as an arc-shaped or flat head) can be replaced. According to the size of the next batch of bricks, the front-to-back or lateral position of the auxiliary pressing mechanism 40 can be readjusted.

[0031] Working principle: The adjustment groove 100 on the top of the connecting plate 10 is used to adjust the position of the auxiliary pressing mechanism 40. The adjustment plate 402 is fixed by bolts 404 so that the second cylinder 400 can move back and forth. The first cylinder 300 of the clamping mechanism 30 pushes the telescopic rod 302, which drives the pivot plate 308 to pull the first connecting rod 312 to rotate the movable arm 310 around the hinge point of the second connecting rod 314, thereby realizing the opening and closing of the clamping part. At the same time, the cross bar 3160 and the clamping rod 3162 on the mounting plate 316 cooperate to reinforce the supporting bent rod 3180 at the bottom of the connecting plate 318 to clamp the brick. The second cylinder 400 of the auxiliary pressing mechanism 40 drives the fixed plate 406 to press down, so that the upper pressing plate 408 presses the center of the brick through the side baffle 410 and the clearance groove 412 (avoiding the clamping rod 3162), thereby working with the clamping mechanism 30 to complete the stable gripping and positioning of the brick.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
