Technical Field

[0001] The utility model relates to the technical field of convenient pliers-type clamps for road base blocks, in particular to a convenient pliers-type clamp for road base blocks with high safety. Background Art

[0002] In the field of lifting technology, the construction of prefabricated road base is to assemble prefabricated concrete parts on site. According to the process requirements, the prefabricated parts must be clamped on the side for assembly. Based on the various types of lifting equipment required, different clamps are required to achieve the lifting of different equipment. At present, most of the lifting equipment has lifting holes directly on the equipment, and then the lifting is achieved through lifting rings. Ordinary scissor-type clamps are used, which have insufficient clamping force and poor safety.

[0003] After searching, Chinese Patent Publication (Announcement) No. 201621385203.8 discloses a convenient pliers-type clamp for road base blocks. This patent increases the clamping force of the splint and improves the working reliability of the clamp by reasonably arranging the lever shaft position. Although the above patent has the effect of increasing the clamping force, it does not have an anti-falling function. After the road base block is clamped, once the clamp becomes loose due to aging, there is still a risk of falling in the later stage. Therefore, it is necessary to have an anti-falling effect on the base block to prevent it from falling directly to the ground. Moreover, the current clamp does not have the function of adjusting the clamping angle. Therefore, it is necessary to design a convenient pliers-type clamp for road base blocks with high safety.

[0022] Example 1

[0023] like Figure 1-4 As shown, a convenient clamp-type clamp for a road base block with high safety includes a right movable plate 1, one end of the right movable plate 1 is rotatably connected to a left movable plate 2, one side of the outer surface of the right movable plate 1 and the left movable plate 2 is fixedly connected to a cross bar 3, and both ends of the cross bar 3 are rotatably connected to an anti-fall frame 4;

[0024] In this embodiment, a pull rope 5 is fixedly connected to one side of the outer surface of the anti-fall frame 4 near the bottom end, an inclined column 6 is fixedly connected to one side of the upper surface of the right movable plate 1 and the left movable plate 2, a pulley block 7 is rotatably connected to the top of the inclined column 6, a bracket 8 is fixedly connected to one side of the upper surface of the right movable plate 1 and the left movable plate 2, and a limiting rod 9 is threadedly connected to the upper surface of the bracket 8.

[0025] When in use, first fix the clamp on the crane, and place the hoist on both sides of the roadbed. The left movable plate 2 contacts the base block and is pulled upward by the crane to rotate with the right movable plate 1, so that a clamping force is generated between them to lift the roadbed block. After the roadbed block is suspended in the air, loosen the limit rod 9, so that the anti-fall frame 4 falls naturally to the bottom of the roadbed block under the action of gravity. After the two groups of anti-fall frames 4 fall at the same time, the roadbed block accidentally falls and falls on the anti-fall frame 4, thereby avoiding directly hitting the ground. When the roadbed block is about to be unloaded, pull the pull rope 5 to flip the anti-fall frames 4 on both sides to both sides. Tighten the limit rod 9 and press the pull rope 5 downward to temporarily fix it, which is convenient for normal unloading of the roadbed block.

[0026] In this embodiment, one end of the limiting rod 9 passes through the upper surface of the bracket 8 and extends to the inner top wall of the bracket 8 , and the pull rope 5 is located between the pulley blocks 7 .

[0027] When in use, the pull rope 5 passes through the pulley block 7 and one end of the pull rope 5 is pulled to make the pull rope 5 slide more easily to drive the anti-fall frame 4 to flip.

[0028] In this embodiment, one end of the left movable plate 2 is rotatably connected to a U-shaped plate 10 , and the U-shaped plate 10 is movably connected to the right movable plate 1 .

[0029] When in use, through the rotation effect of the U-shaped plate 10 and the left movable plate 2, after the U-shaped plate 10 is pulled upward, one end of the left movable plate 2 can be subjected to a force to flip over.

[0030] In this embodiment, a hook 11 is fixedly connected to the upper surface of the U-shaped plate 10 .

[0031] When in use, the clamp is conveniently hung on a crane through the hook 11. Under the action of gravity, after the crane is started, a clamping force can be generated between the clamps to lift the roadbed block.

[0032] In this embodiment, one side of the outer surface of the right movable plate 1 and the left movable plate 2 is rotatably connected to a support column 12 , and one end of the support column 12 is fixedly connected to a clamping plate 13 .

[0033] When in use, the right movable plate 1 and the left movable plate 2 are subjected to gravity and upward pulling force, and can drive the clamping plate 13 to produce a clamping effect.

[0034] In this embodiment, a latch 14 is inserted into one end of the support column 12 away from the clamping plate 13 .

[0035] When in use, the support column 12 is temporarily fixed by inserting the latch 14 into the positioning hole 15 .

[0036] In this embodiment, a positioning hole 15 is formed on one side of the outer surface of the right movable plate 1 and the left movable plate 2 close to the support column 12 , and the size of the positioning hole 15 is adapted to the latch 14 .

[0037] When in use, after the latch 14 is pulled out, the clamping plate 13 is rotated to a vertical angle. At this time, the clamping plate 13 can fit the roadbed block to the greatest extent after being turned over.

[0038] Working principle: During use, first fix the clamp on the crane, and place the hanger on both sides of the roadbed. When encountering a wider roadbed block, the clamping plate 13 can be rotated to a horizontal angle through the rotation effect of the support column 12 and the right movable plate 1 and the left movable plate 2, and then the support column 12 is temporarily fixed by inserting the pin 14 into the positioning hole 15. The wider roadbed block can be clamped through the horizontal clamping plate 13. When encountering a narrow roadbed block, pull out the pin 14 and then rotate the clamping plate 13 to a vertical angle. At this time, the clamping plate 13 can fit the roadbed block to the greatest extent after flipping, which is convenient for adjustment. Angle function is used to adapt to different roadbed blocks. Under the action of gravity, the left movable plate 2 contacts the base block and is pulled upward by the crane to rotate with the right movable plate 1. The friction and clamping force with the roadbed block enable the clamp to clamp the roadbed block. After the roadbed block is suspended in the air, the limit rod 9 is loosened to make the anti-fall frame 4 naturally fall to the bottom of the roadbed block under the action of gravity. After the two groups of anti-fall frames 4 fall at the same time, the roadbed block accidentally falls and falls on the anti-fall frame 4, thereby avoiding directly hitting the ground. When the roadbed block is about to be unloaded, the pull rope 5 is pulled to flip the anti-fall frames 4 on both sides to both sides, so as to facilitate the normal unloading of the roadbed block.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
