[0002] In the channel engineering slope lining construction in agricultural irrigation areas, the laying of hexagonal bricks is an important and tedious work. The traditional laying method mostly relies on manual carrying and laying one by one, which is extremely low in efficiency and consumes a large amount of labor and time cost. Moreover, the workers are high in labor intensity and easy to be tired in the process of manual carrying, which leads to uneven laying quality. Meanwhile, the manual operation is more difficult in complex terrains such as slopes, and it is difficult to guarantee the laying precision, stability and safety. At present, although some auxiliary equipment is used for carrying building materials, there are few devices that are specially used for laying hexagonal bricks in the channel engineering slope lining construction in agricultural irrigation areas and can realize efficient and accurate laying, which cannot meet the needs of modern engineering rapid and high-quality construction. Therefore, it has important practical significance to develop a laying clamp that can improve the laying efficiency of hexagonal bricks, reduce labor intensity and adapt to different terrains.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] To address the aforementioned issues, this application provides a high-efficiency hexagonal brick hoisting clamp based on the principle of self-weight clamping. This clamp can improve the efficiency and quality of hexagonal brick laying during the construction of slope protection lining in irrigation canal projects, reduce labor intensity, and also possesses good versatility and adaptability.

[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] See Figure 1The hexagonal brick high-efficiency lifting fixture based on the self-weight clamping principle includes a main load-bearing beam 1. The main load-bearing beam 1 has adjustable clamping arms 2 symmetrically arranged on both sides. The clamping arms 2 are evenly distributed along the axial direction of the main load-bearing beam 1. The clamping arms 2 are connected to the main load-bearing beam 1 by hinge bolts 21. The movable end of the clamping arm 2 is provided with a clamping hand 5, and the movable end of the clamping arm 2 is provided with a through hole. The clamping arm linkage rod 4 is provided through the through hole with clearance fit. The two ends of the clamping arm linkage rod 4 are detachably provided with limiting baffles 41. The top of the main load-bearing beam 1 is eccentrically fixed with a lifting connecting plate 3. The lifting connecting plate 3 is evenly provided with lifting holes 31.

[0025] The length of the main load-bearing beam 1 is set according to the size, spacing and construction allowance of the hexagonal bricks. Six pairs of adjustable clamping arms 2 are symmetrically distributed on both sides. The hoisting connecting plate 3 is eccentrically fixed to the top of the main load-bearing beam 1. Multiple hoisting holes 31 are evenly opened laterally to adjust the hoisting angle of the clamps. The clamping arm linkage rod 4 is made of high-strength steel, which passes through the through hole at the top of the clamping arm 2 and is in clearance fit with the clamping arm 2. Removable limit baffles 41 are set at both ends. The clamping force of the clamping arm 2 is enhanced by the counterweight linkage. The movable end of the clamping arm is equipped with a clamping hand 5, which closes and clamps the hexagonal bricks by the weight of the clamping arm during hoisting.

[0026] The main body of the clamp uses high-strength rectangular steel as the load-bearing beam. Its length is set according to the size and quantity of the hexagonal bricks to be laid, the spacing between adjacent bricks required by the engineering design, and the allowance at both ends. The length of the clamp arm 2 is set according to the size of the hexagonal bricks. All clamp arms 2 are welded from high-strength steel.

[0027] The clamping arms 2 are evenly arranged on the main load-bearing beam 1 according to the size and design spacing of the hexagonal bricks. Each pair of clamping arms 2 consists of two high-strength steel plates, which are connected and fixed by hinge bolts 21, and a certain amount of movement clearance is maintained to ensure the freedom of movement of the clamping arms 2 on both sides. The top of the clamping arm 2 is provided with a through hole, and a counterweight clamping arm linkage rod 4 made of high-strength steel is added to each clamping arm to form a whole through the clamping arm 2. The ends of the clamping arm linkage rod 4 are provided with detachable limit baffles 41 to prevent falling. The diameter of the through hole of the clamping arm 2 is larger than the diameter of the clamping arm linkage rod 4, so that each clamping arm 2 has a certain amount of movement space. The clamping arm linkage rod 4 is designed to increase the self-weight clamping force of the clamping arm 2, and at the same time, all the clamping arms 2 on one side can be released at once after the bricks are laid to the designated position to release the hexagonal bricks.

[0028] In some implementations, see Figure 2The clamp 5 includes a top flat steel plate 51 and a V-shaped upright steel plate 52. The top flat steel plate 51 is fixed to the bottom of the movable end of the clamp arm 2. The V-shaped upright steel plate 52 is fixedly installed at the bottom of the outer end of the top flat steel plate 51. The openings of the V-shaped upright steel plates 52 on the two symmetrically arranged clamp arms 2 are symmetrically arranged facing each other. The opening angle of the V-shaped upright steel plate 52 matches the corner angle of the hexagonal brick, and the height matches the thickness of the hexagonal brick. The inner side of the V-shaped upright steel plate 52 is provided with a rubber anti-slip pad 53 with protruding ridges.

[0029] The gripper is composed of three high-strength steel plates: one flat on top and two V-shaped upright plates (depending on the angle of the hexagonal brick). At the same time, a rubber anti-slip pad 53 made of rubber material is provided on the contact surface between the gripper and the hexagonal brick. It consists of a bottom layer and a raised edge (serrated) layer, which can greatly enhance the friction between the gripper and the hexagonal brick and effectively prevent the hexagonal brick from slipping during the gripping process.

[0030] In some embodiments, the eccentricity of the hoisting connecting plate 3 is 1 / 4 to 1 / 3 of the length of the main load-bearing beam 1, and the spacing of the hoisting holes 31 is 20-150mm.

[0031] The eccentric setting allows the clamp to tilt to a certain extent when it is lifted. This tilting design makes it easier to lay hexagonal bricks on the slope. Multiple lifting holes 31 are evenly arranged laterally on the lifting connection plate 3 to form an adjustable tilting mechanism. By adjusting the lifting point (i.e., selecting different lifting holes 31), the tilt of the clamp when it is lifted can be adjusted to adapt to channels with different slopes.

[0032] In some embodiments, the height of the raised ridge of the rubber anti-slip pad 53 is 3-5mm, and the serration spacing is 3-15mm.

[0033] In some embodiments, the diameter of the clamping arm linkage 4 is less than 3 / 4 of the diameter of the clamping arm through hole.

[0034] The diameter of the clamping arm linkage rod 4 is less than 3 / 4 of the diameter of the clamping arm through hole, forming an active clearance for a single clamping arm.

[0035] The working process of this application:

[0036] The length of the main load-bearing beam 1 and the spacing of the clamping arms 2 are determined based on the dimensions of the hexagonal bricks. High-strength square steel is selected to construct the main load-bearing beam 1, ensuring the overall strength and stability of the clamping fixture 2 to withstand various stresses during hoisting. The hoisting connecting plate 3, clamping arms 2, clamping hands 5, and clamping arm linkage rod 4 are also made of high-strength steel to ensure sufficient strength to hold the hexagonal bricks. The contact surface between the clamping hands 5 and the hexagonal bricks is made of rubber to create an anti-slip pad, with serrated protrusions added to enhance the anti-slip effect.

[0037] Before construction, based on the channel slope ratio, a suitable lifting hole 31 is selected by calculation or by referring to engineering experience to determine the inclination of the clamp when lifting, so that it can adapt to the channel slope.

[0038] The crane slowly lowers the clamps above the hexagonal bricks that have been arranged in the clamp configuration. The lowering speed should be moderate to avoid violent collisions between the clamps and the hexagonal bricks.

[0039] Workers clamp the hexagonal bricks one by one with the clamping arms 2 that open due to their own weight, ensuring that the clamping arms 2 and the hexagonal bricks are in close contact, and that the rubber anti-slip pads 53 of the clamping hands 5 are in full contact with the hexagonal bricks.

[0040] After confirming that clamp arm 2 is securely holding the hexagonal brick, the worker directs the crane to lift it. The crane lifting process should be smooth and the speed should not be too fast to avoid the hexagonal brick falling due to shaking.

[0041] After the clamp is hoisted above the location where bricks need to be laid, the crane slowly lowers the clamp. At the same time, workers use auxiliary ropes and other tools to fine-tune the position and angle of the clamp to ensure that the clamp can be accurately placed in the paving position.

[0042] After the clamp is lowered to the paving position, the clamp arm 2 is released due to the support of the device on the ground, and the hexagonal bricks are laid. The worker checks whether the laid hexagonal bricks are flat and whether the position is accurate. If necessary, appropriate adjustments are made.

[0043] Repeat the above steps to lay the next set of hexagonal tiles.

[0044] It should be emphasized that the device can automatically clamp the hexagonal bricks using the clamping arms 2 and clamping hands 5, ensuring that the hexagonal bricks do not fall off.
