Description

Technical Field

[0001] The utility model relates to the technical field of bridge repair, in particular to a road and bridge crack reinforcement device. Background Art

[0002] With the development of my country's economy, the increase in vehicle volume and the increasing traffic pressure, bridges are often seriously congested due to the actual traffic load being greater than the original design standard level and the traffic volume far exceeding the design, resulting in an imbalance between supply and demand, which often causes damage to bridge components. In order to ensure their safety, they need to be frequently repaired to meet their functional requirements and extend their service life.

[0003] For bridges with cracks, in order to restore the durability and waterproof performance of the bridge structure, the concrete cracks must be filled. The following technical methods are used: surface repair method, grouting method and filling method. When repairing and reinforcing bridges, the crack filling method is suitable for repairing large cracks. In the specific operation, a deep groove should be chiseled along the crack of the bridge, and then various viscous materials should be filled in the deep groove. For example, asphalt, epoxy resin, expansive cement, cement mortar and a variety of chemical reinforcing agents. When repairing the groove at the crack of the bridge, it is necessary to use a cutter to chisel a deep groove. During the cutting process, the staff needs to hold the cutter to operate. Since some cracks are relatively far away from the lifting platform, the staff operates close to the edge of the platform, which poses a safety hazard. Utility Model Content

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1 , 2 As shown in Figures 3, 4 and 5, a crack reinforcement device for roads and bridges is proposed in this embodiment, including a cutter 8, a handle 7 and a grip rod 6. The cutter 8 and the handle 7 are respectively arranged at both ends of the grip rod 6, and the grip rod 6 is detachably connected to the handle 7 and the cutter 8; the handle 7 and the cutter 8 are both detachably connected to the grip rod 6. After the cutter 8 is removed from the grip rod 6, the staff can hold the cutter 8 to work, and the disassembly, assembly and replacement are convenient.

[0022] An adjustment bracket is provided below the grip 6, and the adjustment bracket includes a support rod 1, a base 2 is provided at the lower end of the support rod 1, a sliding sleeve 3 is provided at the upper end of the support rod 1, the base 2 is rotatably connected to the support rod 1, and the sliding sleeve 3 is rotatably connected to the support rod 1 through a rotating pin 4; the sliding sleeve 3 is rotatably connected to one side of the support rod 1 through the rotating pin 4, and the sliding sleeve 3 can rotate around the rotating pin 4.

[0023] The sliding sleeve 3 is sleeved on the outside of the grip rod 6, and the grip rod 6 is slidably connected with the sliding sleeve 3. The connection between the sliding sleeve 3 and the grip rod 6 is provided with a damping structure for adjusting the tightness between the sliding sleeve 3 and the grip rod 6. The support rod 1 is placed on one side of the bridge repair position, and the tightness between the sliding sleeve 3 and the baffle 5 is adjusted by the damping structure. The grip 7 is held and the grip rod 6 is pushed to make the cutter 8 contact the side of the bridge. The support rod 1, the grip rod 6 and the sliding sleeve 3 are rotated to control the grooving route of the cutter 8. The flexibility is strong, and the long handle structure is matched with the design of the adjustment bracket to effectively improve the safety of bridge crack grooving operations.

[0024] Specifically, the damping structure includes a movable groove 15 provided in the sliding sleeve 3, an arc-shaped rubber pressing block 16 is provided in the movable groove 15, the arc-shaped rubber pressing block 16 is placed above the grip 6, the lower end surface of the arc-shaped rubber pressing block 16 is in contact with the outer wall of the grip 6, the upper end of the arc-shaped rubber pressing block 16 is rotatably connected with a bolt 14 provided at the upper end of the sliding sleeve 3, and the bolt 14 is threadedly connected with the sliding sleeve 3. When the grip 6 is fixed, the bolt 14 is rotated, and the bolt 14 pushes the arc-shaped rubber pressing block 16 in the movable groove 15 to fall down, and the arc-shaped rubber pressing block 16 contacts the grip 6 when falling, and squeezes the grip 6, and limits the sliding and rotation of the grip 6 by friction.

[0025] Specifically, the cutter 8 includes a handle end and a grinding end, a U-shaped handle 13 is provided on the outside of the handle end, and a cutting wheel and a motor for controlling the rotation of the cutting wheel are provided on the outside of the grinding end. After the cutter 8 is installed on the grip 6, the grip 6 can be used to groove the bridge cracks at high and low places, and the cutter 8 can also be removed from the grip 6, and the U-shaped handle 13 on the handle end is held to work.

[0026] When the handle 7 and the cutter 8 are removed from both ends of the grip rod 6, the grip rod 6 can be directly pulled out from the sliding sleeve 3 by sliding the grip rod 6, so that the staff can carry the device separately.

[0027] Regarding the fixation between the cutter 8 and the grip 6: the grip 6 is provided with a first threaded column 10 at one end close to the cutter 8, the first threaded column 10 is fixedly connected to the grip 6, the first threaded column 10 is inserted into the first threaded groove 9 provided at the handle end at one end away from the grip 6, and the first threaded groove 9 is threadedly connected to the first threaded column 10. The cutter 8 and the grip 6 are fixed by threaded connection, and when the cutter 8 is removed from the grip 6, the first threaded column 10 can be screwed out of the first threaded groove 9.

[0028] Regarding the fixation between the grip 6 and the handle 7: the grip 6 is provided with a second threaded column 11 at one end close to the handle 7, the second threaded column 11 is fixedly connected to the grip 6, and the second threaded column 11 is threadedly connected to a second threaded groove 12 provided on the outer side of the handle 7 at one end away from the grip 6. Similarly, the grip 6 and the handle 7 are also fixed by threaded connection, which will not be described here.

[0029] In order to prevent the cutter 8 from falling rapidly due to gravity after the grip 7 is released, causing the grip 6 to rotate significantly and affecting the safety of the staff, a baffle 5 is provided at each end of the sliding sleeve 3, and the two baffles 5 are symmetrically arranged on both sides of the support rod 1, and the baffles 5 are fixedly connected to the sliding sleeve 3. After the grip 7 is released, the grip 6 drives the sliding sleeve 3 to rotate together. When the cutter 8 falls to a certain height, one of the baffles 5 on both sides of the sliding sleeve 3 will conflict with the support rod 1, limiting the sliding sleeve 3 from continuing to rotate, thereby improving the safety of the device.

[0030] Working principle: Place the support rod 1 on one side of the bridge repair position, adjust the tightness between the sliding sleeve 3 and the baffle 5 through the damping structure, hold the handle 7 and push the grip 6 to make the cutter 8 contact the side of the bridge, rotate the support rod 1, grip 6 and sliding sleeve 3 to control the grooving route of the cutter 8. It has strong flexibility, and the long-handled structure is combined with the design of the adjustment bracket to effectively improve the safety of bridge crack grooving operations.

[0031] The above shows and describes the basic principles, main features and 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 principles 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.
