Description

Technical Field

[0001] This utility model belongs to the field of concrete pavement repair technology, specifically relating to a quick positioning clamp for repairing broken concrete pavement slabs. Background Technology

[0002] Concrete pavements are prone to defects such as slab breaks and cracks due to factors such as vehicle loads, environmental temperature changes, material aging, and improper construction and maintenance. If not repaired in time, these defects will continue to expand, affecting the road's traffic safety and service life. In the construction of concrete pavement slab breakage repair, side formwork needs to be set on both sides of the broken area, and new concrete is poured to reinforce and level the defective area.

[0003] Existing side formwork positioning tools mostly use bolt-tightening clamps or simple steel clamping structures. Bolt adjustment or steel splicing operations are cumbersome, require multiple people to work together, are time-consuming, affect construction progress, and have low positioning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick positioning fixture for repairing broken concrete pavement slabs, which can quickly position the opposite side template during the repair process.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A quick positioning clamp for repairing broken concrete pavement slabs includes two side clamps, a telescopic guide is fixedly connected between the two side clamps, and a rope-type tension application group is provided between the two side clamps.

[0007] Furthermore, the pull-rope tension application assembly includes a U-shaped frame fixedly connected to the side clamps, a rotating shaft rotatably connected to the U-shaped frame, a winding shaft and a ratchet fixedly connected to the outer side of the rotating shaft, a pull rope wound on the winding shaft, the end of the pull rope connected to another side clamp, a side support fixedly connected to the U-shaped frame, a pawl adapted to the ratchet rotatably connected to the side support, and a tension spring installed between the pawl and the side support.

[0008] Furthermore, an upper limit plate is fixedly connected to the inner side of the side clamp.

[0009] Furthermore, a limit plate body is fixedly connected to the lower side of the upper limit plate, and a connecting block is fixedly connected to one side of the limit plate body. Multiple limit slots are provided on the side clamp, and the connecting block is engaged in any one of the limit slots.

[0010] The side of the side clamp is provided with a groove, and the limiting plate is located inside the groove.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This utility model discloses a quick positioning clamp for repairing broken concrete pavement slabs. By using a rope-type tension application group to pull the two side clamps, it can quickly move the side clamps. It is suitable for the size of the road surface with a large width, so as to quickly complete the positioning of the side template. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-4 As shown, a quick positioning clamp for repairing broken concrete pavement slabs includes two side clamps 1, a telescopic guide is fixedly connected between the two side clamps 1, and a rope-type tension application group is provided between the two side clamps 1.

[0021] In use, a side template 21 is set on both sides of the broken slab repair area between two concrete pavement slabs 20. The side templates 21 limit the concrete poured in the broken slab repair area on both sides. Then, the two side clamps 1 are placed on the side of the two side templates 21 that are far apart from each other. Then, the two side clamps 1 are clamped on the outside of the two side templates 21 by applying a rope-type tension application group to the two side clamps 1 to bring them closer together. This completes the clamping and positioning of the two side templates 21. By using the rope-type tension application group to pull the two side clamps 1, the side clamps 1 can be moved quickly, which is suitable for the size of the road surface with a large width, so that the positioning of the side templates 21 can be completed quickly.

[0022] like Figures 1-2 As shown, the telescopic guide includes a connecting sleeve 2, on which two sets of auxiliary sleeves 3 are fixedly connected. Two sets of connecting rods 4 are slidably connected inside the two sets of auxiliary sleeves 3. The two sets of connecting rods 4 are fixedly connected to two side clamps 1 respectively. Through the sliding connection between the auxiliary sleeves 3 and the connecting rods 4, the side clamps 1 can be guided, and the two side clamps 1 are always vertically aligned. At the same time, through the setting of the two sets of auxiliary sleeves 3 and connecting rods 4, the connecting rods 4 can be retracted into the area corresponding to the connecting sleeve 2, thereby reducing the length of the telescopic guide after retraction.

[0023] The number of each set of additional sleeves 3 and connecting rods 4 is preferably three. The three additional sleeves 3 or connecting rods 4 are arranged in a ring array with the axis of the connecting sleeve 2 as the center, thereby ensuring stability.

[0024] like Figures 1-3 As shown, the pull-rope type tension application group includes a U-shaped frame 6 fixedly connected to the side clamp 1. A rotating shaft 7 is rotatably connected to the U-shaped frame 6. A winding shaft 8 and a ratchet 12 are fixedly connected to the outside of the rotating shaft 7. A pull rope 5 is wound on the winding shaft 8. The pull rope 5 can be a steel wire rope. The end of the pull rope 5 is connected to another side clamp 1. A side support 9 is fixedly connected to the U-shaped frame 6. A pawl 10 adapted to the ratchet 12 is rotatably connected to the side support 9. A tension spring 11 is installed between the pawl 10 and the side support 9. When the rotating shaft 7 drives the winding shaft 8 to rotate, the rotating shaft 8 can be driven to rotate, winding the pull rope 5. After winding, the winding shaft 8 can be locked by the pawl 10 and the ratchet 12.

[0025] The end of the rotating shaft 7 is fixedly connected to a sleeve 13. The user can directly rotate the sleeve 13 to drive the winding shaft 8 to rotate, or insert a pry bar into the sleeve 13 to drive the sleeve 13 to rotate.

[0026] like Figures 1-2 and Figure 4As shown, in some embodiments, an upper limit plate 14 is fixedly connected to the inner side of the side clamping plate 1. By abutting the top surface of the side template 21 with the upper limit plate 14, the side clamping plate 1 can be limited downward.

[0027] The upper limit plate 14 can be installed by fixing a limit plate body 15 to the lower side of the upper limit plate 14, fixing a connecting block 16 to one side of the limit plate body 15, and opening multiple limit slots 17 on the side clamping plate 1. The connecting block 16 can be engaged in any one of the limit slots 17, thereby adjusting the height of the upper limit plate 14 and clamping the limit plate body 15 with the side clamping plate 1 and the side template 21, thereby improving the connection stability between the limit plate body 15 and the side clamping plate 1.

[0028] A groove 18 is provided on the side of the side clamp 1, and the limiting plate 15 is located inside the groove 18, so that the side clamp 1 can directly contact the side template 21.

[0029] A magnet 19 is fixedly connected to the side clamp 1. The limiting plate 15 is made of iron. The magnet 19 can magnetically reinforce the limiting plate 15.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
