Description

Technical Field

[0001] This utility model relates to a special clamp for prefabricated base courses of asphalt pavement, and more particularly to a special directional control clamp for prefabricated base course block paving. Background Technology

[0002] In recent years, prefabricated base structures for asphalt pavements have been widely used in municipal road engineering. Prefabricated base structures involve transporting factory-produced, qualified precast concrete blocks to the construction site and assembling them into an interlocking whole. This structure has been widely applied in municipal road construction in recent years, demonstrating significant advantages such as short construction period, high strength, long service life, and good weather resistance, achieving remarkable results in emergency road repairs. Each prefabricated base block is 1 square meter in size, 30 cm thick, and weighs approximately 590 kg. The base block is a square precast cement concrete block with three-dimensional interlocking characteristics, constituting the prefabricated base. The prefabricated base block is a C30 plain concrete structure, characterized by four sides. The four sides are arranged with alternating outward and inward sloping surfaces. That is, one pair of opposite sides are arranged in a V-shape with relative symmetry, and another pair of sides are arranged in an inverted V-shape with relative symmetry. Each side also has substructures such as grooves and transverse grooves.

[0003] Due to the large weight of the blocks, they cannot be handled manually, and traditional clamps cannot be quickly deployed or retracted, resulting in slow installation speed. Given the unique and complex shape and structure of the blocks, a rapid clamping tool is needed to replace traditional clamps and accelerate block assembly. Utility Model Content

[0010] When the two connecting ropes are in a relaxed state, the locking mechanism locks the intermediate rope and the pin barrel to make the bottom end of the intermediate rope hoist the support beam, and the two clamping plate bodies are in a loosened state; when the two connecting ropes hoist the support beam by unlocking the pin barrel and the intermediate rope, the inner end of the rotating plate rotates upward and outward to drive the clamping plate body to rotate downward and inward to clamp the clamping groove.

[0011] Further, the locking mechanism includes a locking piece and a cylindrical barrel sleeved in the pin barrel, and the top of the cylindrical barrel is fixedly connected with the intermediate rope;

[0012] The locking piece can lock the axial position of the cylindrical barrel and the pin barrel to make the bottom end of the intermediate rope hoist the support beam;

[0013] The locking piece can unlock the axial position of the cylindrical barrel and the pin barrel to make the cylindrical barrel move upward relative to the pin barrel and reduce the length of the cylindrical barrel sleeved in the pin barrel.

[0014] Further, the bottom end of the cylindrical barrel is additionally provided with a protruding ring, the inner diameter of the top end of the hollow pin barrel is smaller than the protruding ring, and the protruding ring is used to prevent the cylindrical barrel from moving upward and separating from the pin barrel.

[0015] Further, the locking piece includes a hook rotatably connected to the outer surface of the pin barrel;

[0016] A through hole is formed in the pin barrel for one end of the hook to extend into, the locking piece can press the protruding ring, and when the hook rotates away from the through hole, the cylindrical barrel can move upward.

[0017] Further, the positioning mechanism includes a limiting rod located outside the support beam, and the two ends of the limiting rod are fixed to any support beam through a support rod;

[0018] The limiting rod is arranged in parallel with the support beam to be attached to the side surface of the prefabricated base layer base block.

[0038] As shown in Figures 1-5 A special directional control clamp for assembled base block paving is used to clamp a pair of clamping grooves 13 on the assembled base block 1 which are inwardly converging from top to bottom. It comprises a pin cylinder 210, two support beams 25 fixed and arranged opposite to each other on both sides of the pin cylinder 210, a pair of clamping plates 27 arranged between the two support beams 25, a locking mechanism, and two connecting ropes 212 symmetrically distributed;

[0039] The two clamping plates 27 are symmetrically arranged about the pin cylinder 210, and the clamping plate 27 comprises a rotating plate 271 arranged along the length of the support beam 25 and a clamping plate body 272 fixed to the outer end of the rotating plate 271 away from the pin cylinder 2;

[0040] The outer end of the rotating plate 271 is rotatably connected to the support beam 25, and the inner end of the rotating plate 271 close to the pin cylinder 210 is fixedly connected to the end of the connecting rope 212;

[0041] The pin cylinder 210 is connected to the end of the intermediate rope between the two connecting ropes 212 through the locking mechanism, the top end of the intermediate rope and the top end of the two connecting ropes 212 converge to one place and are lifted by external equipment; the two connecting ropes 212 and the two clamping plates 27 are distributed in the shape of an isosceles triangle as a whole.

[0042] When the two connecting ropes 212 are in a slack state, the locking mechanism locks the middle rope and the pin cylinder 210, causing the bottom end of the middle rope to lift the support beam 25, and the two clamping plate bodies 272 are in a loose state; when the two connecting ropes 220 are lifted to support the beam 25 by unlocking the pin cylinder 210 and the middle rope, the inner end of the rotating plate 271 rotates upward and outward, causing the clamping plate body 272 to rotate inward and downward to clamp the clamping groove 13.

[0043] Among them, such as Figure 1 As shown, the prefabricated base block 1 is a cubic structure made of plain concrete. The four sides 12 are arranged with alternating trapezoidal slopes that slope outwards from top to bottom and trapezoidal slopes that slope inwards. Horizontal grooves and clamping grooves 13 are provided on the slopes. A pair of V-shaped clamping grooves 13, located on the slopes, can be used as clamping surfaces.

[0044] In this embodiment, the dedicated directional manipulation fixture 2 is a metal structure. Its main frame is formed by two supporting crossbeams 25 arranged longitudinally and laterally, and laterally at intervals. The two supporting crossbeams 25 are preferably U-shaped with upward openings to reduce weight.

[0045] The pin cylinder 210 is fixed in the middle position of the two supporting crossbeams 25.

[0046] Two clamping plates 27 are symmetrically arranged about the pin cylinder 210, with each clamping plate 27 positioned between two supporting beams 25. The clamping plates 27 are arranged longitudinally along their length. Each clamping plate 27 includes a rotating plate 271 arranged along the length of the supporting beam 25 and a clamping plate body 272 fixed to the rotating plate 271 at its outer end opposite to the pin cylinder 2. The rotating plate 271 and the clamping plate body 272 are vertically integrated, and the clamping plate body 272 is a pair of parallel, upright flat plates. The width of the clamping plate body 272 preferably matches the width of the clamping groove 13. The outer end of the rotating plate 271 is rotatably connected to the supporting beam 25, and the inner end of the rotating plate 271 near the pin cylinder 2 is fixedly connected to the end of the connecting rope 212 via a lifting ring 28. The clamping plates 27 are symmetrically connected to both ends of the supporting beam 25 via rotating shafts 26.

[0047] Preferably, the clamping plate body 272 has uneven raised textures to increase the roughness of the clamp. This results in an uneven textured layer on the inner side of the clamping plate body 272.

[0048] The locking mechanism on the pin cylinder 210 is fixedly connected to the end of the intermediate rope located between the two connecting ropes 212. The top of the intermediate rope and the tops of the two connecting ropes 212 meet at one point and are then lifted by external equipment. The intermediate rope is located directly above the pin cylinder 210, and the two connecting ropes 212 are located on the front and rear sides of the intermediate rope.

[0049] The locking mechanism preferably comprises a locking member and a cylinder 29 which is sleeved in the pin barrel 210. The top of the cylinder 29 is fixedly connected with the middle rope.

[0050] The pin barrel 210 is hollow, and a through hole is formed in the top surface of the pin barrel 210 for the cylinder 29 to pass through.

[0051] The locking member can lock the axial positions of the cylinder 29 and the pin barrel 210, so that the bottom end of the middle rope hoists the support beam 25.

[0052] The locking member can unlock the axial positions of the cylinder 29 and the pin barrel 210, so that the cylinder 29 moves upward relative to the pin barrel 210 and the length of the cylinder 29 sleeved in the pin barrel 210 is reduced.

[0053] The cylinder 29 is a stepped shaft with two diameters. A protruding ring 291 is additionally arranged at the bottom end of the cylinder 29, so that the diameter of the bottom end is larger. The inner diameter of the through hole in the top surface of the pin barrel 210 is smaller than the protruding ring 291, and the protruding ring 291 is sleeved in the pin barrel 210. The protruding ring 291 is used to prevent the cylinder 29 from moving upward and separating from the pin barrel 210.

[0054] When the two connecting ropes 212 are in a relaxed state, the locking mechanism locks the axial positions of the cylinder 29 and the middle rope, so that the bottom end of the middle rope hoists the support beam 25. The two clamping plate bodies 272 are in an unfolded state, that is, the turning plates 271 are horizontally placed or naturally fall by being connected by the two connecting ropes 212. By unlocking the axial positions of the cylinder 29 and the middle rope, the hoisting relationship between the middle rope and the pin barrel is disconnected, and the two connecting ropes 212 hoist the support beam 25. The inner end of the turning plate 271 rotates upward and outward, and drives the clamping plate body 272 to clamp the clamping groove 13. The two clamping plate bodies 272 are arranged in an inverted eight shape and contact the bottom surface of the clamping groove 13, so that the assembled base layer base block 1 can be clamped.

[0055] Specifically, the locking member comprises a hook 211 which is rotationally connected to the outer surface of the pin barrel 210. The curved hook portion of the hook 211 can be flipped up and down.

[0056] A through hole is formed in the pin barrel 210 for one end of the hook 211 to extend into. The end portion of the hook 211 can press the protruding ring 291. When the protruding ring 291 is hoisted upward, the hook 211 is synchronously hoisted upward, so that the middle rope hoists the pin barrel 210. When the hook 211 rotates away from the through hole, the protruding ring 291 loses the pressing action of the hook 211, and the cylinder 29 can move upward. The distance between the pin barrel 210 and the middle rope becomes longer, and the middle rope becomes in a relaxed state.

[0057] The pin barrel is provided with a hook 211, and the inside of the pin barrel can extend into the end of the pin 212. The bottom of the pin 212 is an enlarged structure, and the top surface of the pin barrel is provided with a closing structure matched with the enlarged structure of the bottom of the pin to prevent the pin from falling off. The pin is provided with a lifting ring 28 and a connecting ring on the two side clamps 27, which are bound together by three ropes and connected with the lifting hook. In actual work, the hook is connected with a power machine such as an excavator, and manual operation is used for carrying and paving the base block.

[0058] Preferably, the positioning mechanism further comprises a limiting rod 22 located outside the support beam 25, and the two ends of the limiting rod 22 are fixed to any one of the support beams 25 through a support rod 23. The limiting rod 22 is arranged in parallel with the support beam 25, and is used to fit onto the side surface 12 of the fabricated base layer base block 1. The side surface of the support beam 25 is connected with the limiting rod 22 through the support rod 23. The limiting rod is just fitted with the side surface 12 to prevent the clamp from moving. In this way, the universal special clamp surrounds three adjacent side surfaces of the fabricated base layer base block 1. Preferably, the limiting rod is fitted with the inclined surface on the top edge of the side surface 12, and the diameter of the limiting rod does not exceed the vertical distance of the inclined surface of the top surface of the base block.

[0059] Preferably, the positioning mechanism further comprises an upper supporting rod 21 fixed above the limiting rod 22. In order to manually move the universal special clamp, an upper supporting rod 21 is designed above the limiting rod 22, and the upper supporting rod 21 is parallel to the limiting rod 22. Specifically, the positioning mechanism comprises an upper supporting rod fixed above the limiting rod and two inclined rods, the upper supporting rod is fixed between the top ends of the two inclined rods, and the inclined rods are inclinedly fixed to the support beam; the two ends of the limiting rod are vertically fixedly connected with a vertical connecting rod, and the connecting rod is fixed upward to the middle part of the inclined rod; the support rod fixedly connects the connecting rod and the support beam.

[0060] In actual work, the clamp is operated by a power device such as an excavator, the hook is turned downward and inserted into the through hole reserved in the pin barrel, at this time the middle rope on the pin barrel is pulled tight, and the two clamps 27 are in a loose state. The worker manually moves the clamp above the fabricated base layer base block 1 through the upper supporting rod, the limiting rod is clamped into the side surface of the fabricated base layer base block 1, and the clamp 27 is just placed in the clamping groove 13. Next, the hook is opened, the middle rope on the pin barrel is relaxed, the connecting ropes on the two side clamps are tightened to drive the clamps 27 to be tightened, the clamp is in a clamping state, and the clamping and paving work is completed.

[0061] Preferably, the universal special clamp is made of stainless steel or light alloy material. The rod members of the positioning structure are all hollow to reduce the overall weight of the clamp. The locking mechanism can be a mortise and tenon structure. The connecting rope can be a chain structure to improve the durability. The upper supporting rod, the limiting rod, the connecting rod, the support rod, the cylinder, and the pin barrel can be cylindrical or prismatic.

[0062] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
