Description
Technical Field
[0001] The utility model relates to the technical field of road repair, in particular to a compacting device for road repair. Background Art
[0002] Road transportation is the most basic and important mode of transportation. When cracks or joints appear on the pavement of roads such as highways, airports, pavements, and bridges, the roads need to be repaired to extend their service life. With the development of highway construction and the growth of passenger and freight volume, the demand for road maintenance has also increased significantly and become increasingly urgent.
[0003] The existing road repair method is mostly to fill the cracks in the road surface with asphalt, and then use compaction equipment to pressurize it to complete the repair. However, the existing compaction equipment is usually large in size and very heavy. As a result, when performing small-scale repairs on the road surface, such as repairing potholes, using this type of compaction equipment will make it very cumbersome and inconvenient to move and use, which can easily reduce the efficiency of the repair. Therefore, a road repair compaction device that can be flexibly used is now designed to solve this type of defect. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a compacting device for road repair, which solves the problem that the prior road surface compacting equipment is large in size and cumbersome in use.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a compaction device for road repair, comprising an L-shaped load-bearing frame, both sides of the rear part of the L-shaped load-bearing frame are fixedly connected to cylinders through fixed plates, an I-shaped top plate is fixedly connected between the top ends of the two cylinders, both sides of the top of the I-shaped top plate are provided with lifting slide holes, a lifting pressure rod is slidably installed on the inner side of the lifting slide holes, a road compactor is fixedly connected between the bottom ends of the two lifting pressure rods, a first retreat plate is fixedly connected between the top ends of the two lifting pressure rods, a second retreat plate is fixedly connected to the surface of the lifting pressure rod, and a first spring is sleeved on the surface of the second retreat plate and located between the lifting pressure rod and the I-shaped top plate.
[0006] Preferably, both sides of the bottom of the L-shaped load-bearing frame are fixedly connected to a rectangular bottom frame through openings, and the front and rear parts between the two sides of the inner cavity of the rectangular bottom frame are rotatably connected to rubber wheels through bearings.
[0007] Preferably, guide grooves are provided on both sides of the surface of the L-shaped load-bearing frame, and a sliding pedal is slidably installed on the inner side of the guide groove. Friction pads used in conjunction with rubber wheels are fixedly connected on both sides of the bottom of the sliding pedal. A second spring is fixedly connected between the sliding pedal and the L-shaped load-bearing frame, and two second springs are provided.
[0008] Preferably, the rear portion of the L-shaped load-bearing frame is fixedly connected to a handrail frame via a bracket.
[0009] Preferably, both sides of the top of the sliding pedal are provided with footrest grooves.
[0010] The utility model provides a compacting device for road repair, which has the following beneficial effects compared with the existing technology:
[0011] (1) The compacting device for road repair uses a cylinder to install a type top plate on the front part of the L-shaped load-bearing frame, and installs a lifting pressure rod and a road compacting seat on the inner side of the type top plate. It is used in conjunction with a sliding pedal and a rubber wheel. The arrangement of these structures can make the device simple and lightweight as a whole, without any extra driving equipment to increase the weight. When performing compaction operations, the weight of the operator himself can be used for counterweight to ensure the stability of the device. While the compaction operation is carried out smoothly, the device can also be flexibly moved and conveniently carried, which satisfies current use.
[0012] (2) The road repair compaction device has a second spring and a friction pad installed at the bottom of the sliding pedal. The arrangement of these structures enables a worker to stand on the top of the sliding pedal so that the friction pad can contact the rubber wheel. The friction force generated by the contact between the friction pad and the rubber wheel is used to limit and fix the rubber wheel, thereby effectively ensuring the stability of the roller seat when compacting the road.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-5 The utility model provides a technical solution: a road repair compaction device, comprising an L-shaped load-bearing frame 1, both sides of the rear part of the L-shaped load-bearing frame 1 are fixedly connected to a cylinder 2 through a fixing plate, and the cylinder 2 is started by an external power supply. A type top plate 3 is fixedly connected between the tops of the two cylinders 2, and lifting sliding holes 4 are opened on both sides of the top of the type top plate 3. A lifting pressure rod 5 is slidably installed on the inner side of the lifting sliding hole 4, and a road pressing seat 6 is fixedly connected between the bottom ends of the two lifting pressure rods 5. The road pressing seat 6 is made of stainless steel and is relatively heavy. A first back-stop plate 7 is fixedly connected between the tops of the two lifting pressure rods 5, and a second back-stop plate 8 is fixedly connected to the surface of the lifting pressure rod 5. A first spring 9 is sleeved on the surface of the second back-stop plate 8 and is located between the lifting pressure rod 5 and the type top plate 3. Both sides of the bottom of the L-shaped load-bearing frame 1 are fixedly connected with a rectangular bottom frame 10 through an opening, and the front and rear between the two sides of the inner cavity of the rectangular bottom frame 10 are rotatably connected with rubber wheels 11 through bearing members.
[0021] When in use, the rectangular bottom frame 10 is used to push the equipment to the position to be compacted, and then the staff puts their feet on the inner side of the footrest groove 17 and uses their own body weight to press down the sliding pedal 13 as a whole. After being pressed down, the friction pad 15 at the bottom of the sliding pedal 13 contacts the top of the rubber wheel 11, and the friction pad 15 uses its own friction force with the rubber wheel 11 to fix the rubber wheel 11.
[0022] Furthermore, guide grooves 12 are provided on both sides of the surface of the L-shaped load-bearing frame 1, and a sliding pedal 13 is slidably installed on the inner side of the guide groove 12. Foot grooves 17 are provided on both sides of the top of the sliding pedal 13, and friction pads 15 used in conjunction with the rubber wheel 11 are fixedly connected on both sides of the bottom of the sliding pedal 13. The surface of the friction pad 15 is wrapped with a rubber layer to increase friction. A second spring 14 is fixedly connected between the sliding pedal 13 and the L-shaped load-bearing frame 1, and two second springs 14 are provided. The rear part of the L-shaped load-bearing frame 1 is fixedly connected to a handrail frame 16 through a bracket.
[0023] Hold the handrail 16 with your hands and start the cylinder 2. When the cylinder 2 is started, it will pull the I-type top plate 3 to push the roller seat 6 down to compact the asphalt, and the first spring 9 on the surface of the lifting pressure rod 5 can serve as a buffer. At the same time, the staff stands on the top of the sliding pedal 13 to increase the counterweight, ensuring that the roller seat 6 can remain stable during the process of compacting the road surface. When it is necessary to move the position, the staff comes down from the top of the sliding pedal 13, allowing the sliding pedal 13 to rise under the elastic force of the second spring 14, and at the same time the friction pad 15 is separated from the rubber wheel 11, and then the equipment is pushed to move.
