Description

Technical Field

[0001] This utility model relates to the field of road maintenance equipment technology, and more specifically to a road pit repair device. Background Technology

[0002] The plate compactor, a key mechanical device for road foundation pit repair, is used to compact soil, gravel, asphalt, and other materials in road foundation pit repair operations. Its working principle is based on the centrifugal force impact generated by the rotation of the eccentric block. Taking the internal combustion plate compactor as an example, the internal combustion engine drives the eccentric device through the clutch and pulley, thereby generating vibration. Since the base plate and the eccentric device are fixedly connected, the operator can flexibly change the vibration direction by rotating the eccentric block, and realize the adjustment between forward vibration, in-situ vibration, and backward vibration.

[0003] However, traditional plate compactors have a significant problem in practical operation: the surface of the plate at the bottom of the machine easily accumulates debris, especially in asphalt pavement repair. Because asphalt is highly viscous, it becomes semi-fluid at high temperatures. Once the plate compactor comes into contact with the asphalt, the asphalt quickly adheres to the plate surface. As the work continues, the amount of adhered asphalt increases. This asphalt and other debris adhering to the bottom of the plate compactor forms an isolation layer between the plate and the compacted material, hindering the effective transfer of the compactor's vibration energy to the compacted asphalt pavement. This ultimately leads to uneven compaction, affecting not only the pavement's smoothness and compaction quality but also reducing its load-bearing capacity and service life. For example, if the pavement needs to meet a specific density standard, the asphalt on the plate surface will prevent some areas from meeting the standard, thus affecting the overall pavement quality. Furthermore, manually cleaning this adhered asphalt debris is not only time-consuming and labor-intensive but also prolongs equipment downtime, severely impacting construction efficiency.

[0005] This utility model provides the following technical solution: a road foundation pit repair device, including a plate compactor body, a roller bracket installed on the plate compactor body, a base fixedly connected to the bottom of the plate compactor body, and a base plate fixedly attached to the bottom of the base. Limiting grooves are opened on both sides of the base, and toothed grooves are fixedly and equidistantly opened inside the limiting grooves near the base plate. Moving components are installed on both sides of the base, and a cleaning component is installed between the two moving components. The moving component includes a fixing plate that fits against the outer surface of the base. A motor is fixedly installed inside the fixing plate, and a gear is fixedly connected to the output end of the motor. A positioning groove is formed inside the fixing plate, and a fixing rod is fixedly connected inside the positioning groove. A sliding block is slidably connected to the outer surface of the fixing rod, and a fixing shaft is fixedly connected to the side of the sliding block. A rubber wheel is rotatably connected to the outer surface of the fixing shaft through a bearing. A turntable is rotatably connected inside the sliding block, and a fastening bolt is fixedly connected to the surface of the turntable.

[0006] Furthermore, the cleaning assembly includes a fixed base fixedly connected to the surface of the fixed plate, a positioning bolt threaded on the back of the fixed base, a sliding groove opened inside the fixed base, a backing plate and a sliding plate slidably connected inside the sliding groove, springs fixedly connected at equal intervals to the opposite surfaces of the backing plate and the sliding plate, a connecting plate fixedly connected to the surface of the sliding plate, and a scraper fixedly connected to the surface of the connecting plate.

[0007] Furthermore, the surface of the scraper abuts against the surface of the base plate, and both the gear and the rubber wheel are rotatably connected inside the limiting groove. The surface of the gear meshes with the inner wall of the tooth groove, and the surface of the rubber wheel abuts against the inner wall of the limiting groove.

[0008] Furthermore, a wireless receiver controller and a battery electrically connected to the motor are fixedly installed inside the fixed plate, and the motor is controlled to start and stop via a wireless switch.

[0009] Furthermore, the outer surface of the fastening bolt is threadedly engaged with the inside of the fixing plate, and the sliding block is slidably connected to the inside of the positioning groove via the fixing rod.

[0010] Furthermore, one end of the positioning bolt near the abutment extends into the interior of the groove and abuts against the surface of the abutment, the surface of the scraper is conical, and the tip of the scraper extends to the outside of the fixing seat.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model, by installing a moving component and a cleaning component, opens the roller bracket and lifts the entire plate compactor body. After the base plate leaves the ground, the motor is started, driving the gears to rotate. Through the meshing of the gears and tooth grooves, the moving component and the cleaning component move as a whole. The elasticity of the spring causes the scraper surface to press against the surface of the base plate, automatically cleaning the surface of the base plate. This reduces the workload and labor intensity of manual cleaning, improves cleaning efficiency, saves labor and time costs, thereby reducing equipment downtime and improving equipment working efficiency.

[0012] 2. This utility model, by setting a sliding back plate, can push the back plate by rotating the positioning bolt, thereby reducing the gap between the back plate and the sliding plate. Through the elasticity of the spring, the pressure between the scraper and the bottom plate surface can be increased. By adjusting the pressure, it can adapt to cleaning different types of sticky substances in different working scenarios. Attached Figure Description

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figure 1 - Figure 4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Figure 4 The present invention will be further described below.

[0017] A road pit repair device includes a plate compactor body 1, a roller bracket 2 installed on the plate compactor body 1, a base 3 fixedly connected to the bottom of the plate compactor body 1, and a base plate 4 fixedly attached to the bottom of the base 3. Limiting grooves 5 are provided on both sides of the base 3. Toothed grooves 6 are fixedly and equidistantly provided in the limiting grooves 5 near the interior of the base plate 4. Moving components 7 are installed on both sides of the base 3, and a cleaning component 8 is installed between the two moving components 7. The moving component 7 includes a fixing plate 71 that is attached to the outer surface of the base 3. A motor 72 is fixedly installed inside the fixing plate 71. A gear 73 is fixedly connected to the output end of the motor 72. A positioning groove 74 is opened inside the fixing plate 71. A fixing rod 75 is fixedly connected inside the positioning groove 74. A sliding block 76 is slidably connected to the outer surface of the fixing rod 75. A fixing shaft 77 is fixedly connected to the side of the sliding block 76. A rubber wheel 78 is rotatably connected to the outer surface of the fixing shaft 77 through a bearing. A turntable 79 is rotatably connected inside the sliding block 76. A fastening bolt 710 is fixedly connected to the surface of the turntable 79. The cleaning component 8 includes a fixed base 81 fixedly connected to the surface of the fixed plate 71. A positioning bolt 82 is threaded on the back of the fixed base 81. A sliding groove 83 is opened inside the fixed base 81. A support plate 84 and a sliding plate 86 are slidably connected inside the sliding groove 83. Springs 85 are fixedly connected at equal intervals to the opposite surfaces of the support plate 84 and the sliding plate 86. A connecting plate 87 is fixedly connected to the surface of the sliding plate 86. A scraper 88 is fixedly connected to the surface of the connecting plate 87.

[0018] In this implementation scheme, by installing the moving component 7 and the cleaning component 8, the roller bracket 2 is opened, and the main body 1 of the plate compactor is supported and lifted. After the base plate 4 leaves the ground, the motor 72 is started, which drives the gear 73 to rotate. Through the meshing of the gear 73 with the tooth groove 6, the moving component 7 and the cleaning component 8 move as a whole. Through the elasticity of the spring 85, the surface of the scraper 88 is pressed against the surface of the base plate 4, and the surface of the base plate 4 is automatically cleaned. This reduces the workload and labor intensity of manual cleaning, improves cleaning efficiency, saves labor and time costs, thereby reducing equipment downtime and improving equipment working efficiency.

[0019] Specifically, the surface of the scraper 88 abuts against the surface of the base plate 4, and the gear 73 and the rubber wheel 78 are rotatably connected inside the limiting groove 5. The surface of the gear 73 is meshed with the inner wall of the tooth groove 6, and the surface of the rubber wheel 78 abuts against the inner wall of the limiting groove 5.

[0020] In this embodiment, the rubber wheel 78 abuts against the inner wall of the limiting groove 5, so that the gear 73 and the tooth groove 6 can mesh tightly.

[0021] Specifically, a wireless receiver controller and a battery electrically connected to the motor 72 are fixedly installed inside the fixed plate 71, and the motor 72 is controlled to start and stop via a wireless switch.

[0022] In this implementation plan, by setting up a wireless receiver controller and battery, the staff can remotely control the motor 72 to start and stop cleaning the bottom of the base plate 4 while holding the main body 1 of the flat plate compactor.

[0023] Specifically, the outer surface thread of the fastening bolt 710 is engaged with the inside of the fixing plate 71, and the sliding block 76 is slidably connected to the inside of the positioning groove 74 through the fixing rod 75.

[0024] In this embodiment, by rotating the fastening bolt 710, the sliding block 76 can be driven to slide inside the positioning groove 74.

[0025] Specifically, the end of the positioning bolt 82 near the abutment plate 84 extends into the interior of the groove 83 and abuts against the surface of the abutment plate 84. The surface of the scraper 88 is conical, and the tip of the scraper 88 extends to the exterior of the fixing seat 81.

[0026] In this embodiment, by setting a sliding back plate 84, rotating the positioning bolt 82 can push the back plate 84, reducing the gap between the back plate 84 and the sliding plate 86. Then, by the elasticity of the spring 85, the pressure between the scraper 88 and the surface of the base plate 4 can be increased. By adjusting the pressure, it can adapt to cleaning different types of adhesives in different working scenarios.

[0027] The working principle and usage process of this utility model are as follows: Before using the plate compactor body 1, by rotating the fastening bolt 710, the sliding block 76 is driven to slide away from the motor 72. At this time, the rubber wheel 78 slides away from the gear 73 until the surface of the rubber wheel 78 is tightly pressed against the inner wall of the limiting groove 5. The surface of the gear 73 is then engaged with the inside of the tooth groove 6, ensuring the stability of the movement of the fixed plate 71. Then, after opening the roller bracket 2, pressure is applied to the plate compactor body 1 through the handrail on the plate compactor body 1, so that the bottom plate 4 is suspended in the air. Then, by starting the motor 72, the motor 72 drives the gear 73 to rotate. Through the meshing of the gear 73 with the tooth groove 6, the moving component 7 is driven. The cleaning assembly 8 moves as a whole, and the surface of the scraper 88 abuts against the surface of the base plate 4 through the elasticity of the spring 85, thus automatically cleaning the surface of the base plate 4. This reduces the workload and labor intensity of manual cleaning, improves cleaning efficiency, saves labor and time costs, and reduces equipment downtime, thereby improving equipment efficiency. By setting a sliding abutment 84, rotating the positioning bolt 82 can push the abutment 84. When the gap between the abutment 84 and the sliding plate 86 is reduced, the elasticity of the spring 85 can increase the pressure between the scraper 88 and the surface of the base plate 4. By adjusting the pressure, it can adapt to cleaning different types of sticky substances in different working scenarios.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
