Description

Technical Field

[0001] This utility model relates to a concrete pavement compaction and protection device, belonging to the technical field of concrete pavement protection equipment. Background Technology

[0002] Concrete pavement refers to pavement with cement concrete slabs as the surface layer. It is a pavement structure consisting of cement concrete slabs as the surface layer, with a base layer and a subbase layer underneath. It is also known as rigid pavement. After concrete pavement is laid, curing blankets need to be laid to protect it, and protective equipment is required at this time.

[0003] According to CN221094642U, a concrete pavement compaction and protection device is disclosed, including a support frame and a rotating rod for wrapping a curing blanket. The rotating rod is rotatably connected to the support frame, and a cutting component is provided on the support frame. The cutting component includes a sliding rod, which is arranged parallel to the rotating rod. Both ends of the sliding rod are fixedly connected to the support frame. A sliding sleeve is slidably fitted on the sliding rod, and a blade is provided on the sliding sleeve. The device also includes a driving component and a resetting component. The driving component is used to drive the sliding sleeve to slide along the sliding rod on the side opposite to the blade cutting surface, and the resetting component is used to drive the sliding sleeve to slide along the sliding rod on the side facing the blade cutting surface. The purpose of this invention is to solve the technical problems of existing cutting scissors, which require constant pressing of the handle to cut the curing blanket, resulting in slow cutting speed and increased workload for workers. While the aforementioned device facilitates cutting the curing blanket, during installation, workers need to use tools such as wooden trowels or scrapers to compact the blanket and prevent bulging or curling edges in order to ensure a tight fit between the blanket and the concrete surface without gaps. This results in high labor intensity for workers and low practicality of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete pavement compaction and protection device. This utility model can facilitate the cutting of the curing blanket, improve the laying effect of the curing blanket, reduce the labor intensity of workers, and improve the practicality of the device, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A concrete pavement compaction and protection device includes a housing, which contains a first cavity and a second cavity. A material roller is rotatably mounted on the upper inner wall of the first cavity. A cylinder is fixedly mounted on the inner wall of one side top of the second cavity. A movable plate is fixedly connected to the output end of the cylinder. A U-shaped frame is fixedly mounted at the bottom end of the movable plate. A flattening roller is rotatably mounted in the lower part of the U-shaped frame. Cylinders are symmetrically fixed at the top end of the movable plate. The output ends of cylinders extend to the bottom of the movable plate and are fixedly connected to crossbars. A mounting plate is slidably mounted at the bottom end of the crossbar. A cutter is fixedly mounted at the bottom end of the mounting plate. A channel for the flattening roller and crossbar to move is opened through the bottom end of the housing. A through groove for the curing blanket to pass through is opened through the inner wall of the bottom end of the first cavity.

[0007] Furthermore, rollers are fixedly installed at the four corners of the bottom of the box, and a push rod is fixedly installed on the upper outer wall of one side of the box.

[0008] Furthermore, a door is hinged to the top of the box.

[0009] Furthermore, a transparent observation window is fixedly embedded through the front side of the box, and the rear side of the transparent observation window is located inside the cavity.

[0010] Furthermore, a plurality of sliding rods are symmetrically and slidably embedded on the side of the movable plate away from the cylinder one, and both ends of the sliding rods are fixedly connected to the inner wall of the side adjacent to the cavity two.

[0011] Furthermore, a groove is provided at the bottom end of the crossbar, and a motor is fixedly installed on the inner wall of one side of the groove. A screw is fixedly connected to the output end of the motor, and a slider is threaded onto the screw. The bottom end of the slider is fixedly connected to the top end of the mounting plate.

[0013] The beneficial effects of this utility model are:

[0014] This invention, by incorporating a flattening roller and a cutter, allows for the flattening of the maintenance blanket. One end is laid on the concrete pavement through a groove. A cylinder pushes a moving plate downwards, causing the moving plate to move the crossbar and U-shaped frame downwards outside the housing. This allows the flattening roller to press the maintenance blanket flat on the pavement. After the blanket is laid, a second cylinder pushes the crossbar downwards to a suitable height. A motor then drives a screw to rotate, causing a slider to move within a groove. The slider moves the mounting plate and cutter back and forth, allowing the cutter to cut the maintenance blanket. This invention facilitates blanket cutting, improves the laying effect, reduces worker fatigue, and enhances the device's practicality. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Example 1 Figures 1-6 This utility model provides a technical solution:

[0025] A concrete pavement compaction and protection device includes a housing 1, which contains a first cavity 2 and a second cavity 3. A material roller 4 is rotatably mounted on the upper inner wall of the first cavity 2. A cylinder 5 is fixedly mounted on the inner wall of one side top of the second cavity 3. A movable plate 6 is fixedly connected to the output end of the cylinder 5. A U-shaped frame 7 is fixedly mounted at the bottom end of the movable plate 6. A flattening roller 8 is rotatably mounted in the lower part of the U-shaped frame 7. Cylinders 9 are symmetrically fixed at the top end of the movable plate 6. The output ends of cylinders 9 extend to the bottom of the movable plate 6 and are fixedly connected to a crossbar 10. An installation plate 11 is slidably mounted at the bottom end of the crossbar 10. A cutter 12 is fixedly mounted at the bottom end of the installation plate 11. A channel for the flattening roller 8 and the crossbar 10 to move is opened through the bottom end of the housing 1. A through groove for the curing blanket to pass through is opened through the inner wall of the bottom end of the first cavity 2.

[0026] Specifically, such as Figures 1-6 As shown, rollers 13 are fixed at the four corners of the bottom of the box 1, and push rods 14 are fixed on the upper outer wall of one side of the box 1. By setting push rods 14 and rollers 13, the device can be moved easily.

[0027] Specifically, such as Figures 1-6 As shown, a door 15 is hinged to the top of the box 1, and a transparent observation window 16 is fixedly embedded through the front side of the box 1. The rear side of the transparent observation window 16 is located inside the cavity 2. By setting the door 15, it is convenient to replace the material roller 4. By setting the transparent observation window 16, the situation inside the cavity 2 can be observed.

[0028] Specifically, such as Figures 1-6As shown, a groove 18 is provided at the bottom end of the crossbar 10. A motor 19 is fixedly installed on the inner wall of one side of the groove 18. A screw 20 is fixedly connected to the output end of the motor 19. A slider 21 is threaded onto the screw 20. The bottom end of the slider 21 is fixedly connected to the top end of the mounting plate 11. The motor 19 drives the screw 20 to rotate, causing the screw 20 to move the slider 21 within the groove 18. The slider 21 can drive the mounting plate 11 and the cutter 12 to move back and forth, so that the cutter 12 can cut the maintenance blanket.

[0029] Specifically, such as Figures 1-6 As shown, the cutter 12 is fixedly connected to the mounting plate 11 by locking screws, which facilitates the disassembly and replacement of the cutter 12.

[0030] Please refer to Example 2 Figures 1-6 The difference between this embodiment and embodiment 1 is that: multiple sliding rods 17 are symmetrically and slidably embedded on the side of the moving plate 6 away from the cylinder 5. Both ends of the sliding rods 17 are fixedly connected to the inner wall of the cavity 3 adjacent to the moving plate 6. When the moving plate 6 moves, the sliding rods 17 can support the moving plate 6.

[0031] The working principle of this utility model is as follows: In use, one end of the maintenance blanket is laid on the concrete road surface after passing through the groove. At this time, the cylinder 5 pushes the moving plate 6 downward, which causes the moving plate 6 to drive the crossbar 10 and the U-shaped frame 7 to move downward to the outside of the box 1. Then, the flattening roller 8 flattens the maintenance blanket on the road surface. When the moving plate 6 moves, the sliding rod 17 can support the moving plate 6. Then, the pushing device moves to lay the maintenance blanket. After the maintenance blanket is laid, the cylinder 9 pushes the crossbar 10 downward to a suitable height. Then, the motor 19 drives the screw 20 to rotate, which causes the screw 20 to drive the slider 21 to move in the sliding groove 18. The slider 21 can drive the mounting plate 11 and the cutter 12 to move back and forth, so that the cutter 12 can cut the maintenance blanket.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
