Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance, in particular to a tamping device for highway maintenance. Background Art

[0002] Highway maintenance refers to the regular maintenance and upkeep of roads, bridges, tunnels and other structures in the highway system. The main purpose of highway maintenance is to extend the service life of the highway, ensure road safety and smooth traffic, improve driving comfort, reduce the occurrence of traffic accidents, and ensure the normal operation of the highway system. During highway maintenance, compaction devices are often needed to compact the roadbed, pavement and other earthwork materials to improve their density and stability.

[0003] When using the current compaction device, workers are required to hold the handle to push the device to move. However, since the compaction device has a certain weight, it will consume a lot of workers' physical strength and increase labor intensity during long-term compaction operations. In addition, the device will vibrate during the compaction process. Holding the handle for a long time will cause worker hand fatigue and discomfort, and even cause vibration injuries. Utility Model Content

[0004] The utility model aims to provide a tamping device for road maintenance which can avoid manual pushing, reduce labor intensity and reduce hand discomfort.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A compacting device for road maintenance includes a mounting plate, two first support columns are mounted on one side of the bottom length direction of the mounting plate, a universal wheel is mounted on the bottom of the first support column, two second support columns are mounted on the other side of the bottom length direction of the mounting plate, a connecting shaft is rotatably mounted between the two second support columns, and moving wheels are mounted on both ends of the connecting shaft. A dual-axis motor is mounted on the upper surface of the mounting plate, a lifting plate is arranged on the lower side of the mounting plate, connecting columns are mounted at the four corners of the lower surface of the lifting plate, and compacting plates are arranged at the ends of the four connecting columns, a lifting mechanism is arranged between the two output shafts of the dual-axis motor and the lifting plate, and a transmission mechanism is arranged between the two output shafts of the dual-axis motor and the connecting shaft.

[0007] It can be seen that through the setting of the lifting mechanism, during the starting process of the dual-axis motor, the tamping plate can be driven to lift and lower back and forth to compact the road surface, and through the setting of the transmission mechanism, during the compaction process, the connecting shaft can be driven to rotate and the moving wheel can be driven to rotate, thereby achieving the purpose of automatic movement of the entire device, without the need for manual push, reducing the labor intensity of workers, and through the setting of the dual-axis motor, two force points can be provided for the lifting plate and the connecting shaft, making its structure stable and reliable, and through the setting of the universal wheel and the moving wheel, the angle of the forward direction of the device can be adjusted to adapt to road conditions.

[0008] Furthermore, the lifting mechanism includes a disc installed at the end of the output shaft of the dual-axis motor, and the outer surface of the disc is rotatably connected to a first connecting rod on the side away from the center of the disc, and a first through groove is opened on the surface of the mounting plate, and the end of the first connecting rod extends through the first through groove to the lower side of the mounting plate, and the end of the first connecting rod is rotatably installed with a second connecting rod, and the end of the second connecting rod is connected to the lifting plate, and four limit rods are connected to the bottom of the mounting plate, and the lifting plate is slidably installed on the four limit rods, and the bottom of the two limit rods on one side are jointly installed with a bottom plate.

[0009] When the dual-axis motor is started, its output shaft drives the disc to rotate, and the disc drives the first connecting rod to rise and fall. Since the two ends of the first connecting rod are respectively rotatably connected to the disc and the second connecting rod, and the lifting plate is limited by four limit rods, the lifting plate can be driven to reciprocate in the vertical direction during the lifting of the first connecting rod. When the lifting plate drops to the lowest point, it can drive the tamping plate to tamping the road surface. Through the setting of the bottom plate, the two limit rods on one side can be connected into a whole, thereby improving the stability of the structure and improving the limiting effect of the lifting plate.

[0010] Furthermore, the transmission mechanism includes a second through groove opened on the surface of the mounting plate, a rotating shaft is rotatably installed inside the second through groove, a first pulley group is arranged for transmission between the output shaft of the dual-axis motor and the rotating shaft, and a second pulley group is arranged for transmission between the rotating shaft and the connecting shaft.

[0011] Through the transmission action of the first pulley group, when the dual-axis motor is started, it can drive the rotating shaft to rotate. Due to the transmission action of the second pulley group, the purpose of driving the connecting shaft to rotate can be achieved. The connecting shaft drives the moving wheels at both ends to rotate, thereby driving the entire device to move forward.

[0012] Furthermore, two oblique rods are installed on the outer surface of the mounting plate, mounting blocks are installed at the ends of the two oblique rods, and a handrail is arranged between the two mounting blocks.

[0013] Workers can control the forward direction of the device by holding the handrail.

[0014] Furthermore, a sliding rod is installed inside the mounting block, a slider is slidably installed on the outer surface of the sliding rod, and the two ends of the handrail are respectively connected to the two sliders. Two springs are sleeved on the outer surface of the sliding rod, and the two springs are respectively located on the upper and lower sides of the slider.

[0015] Since the device can automatically move forward during the process of compacting the road surface, it can reduce the contact between the hand and the handrail and reduce the strength of the hand holding the handrail. When the worker holds the handrail, the slide bar can effectively buffer the vibration caused by compacting the road surface, thereby reducing the force of the vibration on the hand and reducing discomfort.

[0016] Furthermore, connecting grooves are provided at the four corners of the upper surface of the tamping plate, and connecting columns are inserted into the connecting grooves. Screw holes are provided on the outer surface of the connecting columns. Four bolts are installed on the outer surface of the tamping plate, and the bolts are matched with the screw holes.

[0017] By setting the connecting grooves, screw holes and bolts, the tamping plates can be easily replaced to meet different work requirements.

[0018] Furthermore, storage boxes are installed on the outer surfaces of the two second support columns.

[0019] By setting up the storage box, workers can conveniently place items in the storage box, and heavy objects can also be placed in the storage box to play a counterweight role and improve the stability of the device.

[0020] Furthermore, a rubber pad is provided on the outer surface of the armrest, and an anti-slip pattern is provided on the outer surface of the rubber pad.

[0021] The provision of the rubber pad can improve the comfort of the hand, increase the friction with the hand, and reduce the possibility of hand slipping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The utility model is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a compacting device for road maintenance includes a mounting plate 100, two first support columns 101 are installed on one side of the bottom length direction of the mounting plate 100, a universal wheel 102 is installed at the bottom of the first support column 101, and two second support columns 103 are installed on the other side of the bottom length direction of the mounting plate 100, a connecting shaft 109 is rotatably installed between the two second support columns 103, and moving wheels 104 are installed at both ends of the connecting shaft 109. A double-axis motor 105 is installed on the upper surface of the mounting plate 100, a lifting plate 106 is arranged on the lower side of the mounting plate 100, and connecting columns 107 are installed at the four corners of the lower surface of the lifting plate 106, and compacting plates 108 are arranged at the ends of the four connecting columns 107, a lifting mechanism 200 is arranged between the two output shafts of the double-axis motor 105 and the lifting plate 106, and a transmission mechanism 300 is arranged between the two output shafts of the double-axis motor 105 and the connecting shaft 109.

[0029] When in use, the dual-axis motor 105 can be started, and its two output shafts rotate at the same time, and through the action of the lifting mechanism 200, the lifting plate 106 is driven to lift and lower back and forth, and the lifting plate 106 drives the tamping plate 108 to lift and lower back and forth through the connecting column 107, thereby achieving the purpose of compacting the road surface, and through the setting of the transmission mechanism 300, the connecting shaft 109 can be driven to rotate during the start-up of the dual-axis motor 105, and the connecting shaft 109 drives the moving wheels 104 at both ends to rotate, thereby driving the entire device to move, thereby avoiding manual pushing and compacting while moving. Workers only need to control the direction, and compaction and movement share a driving source, which not only reduces costs, but also has high coordination between the two functions, reducing the risk of failure.

[0030] Specifically, the lifting mechanism 200 includes a disc 201 installed at the end of the output shaft of the dual-axis motor 105, and the outer surface of the disc 201 is rotatably connected to the first connecting rod 202 on the side away from the center of the circle, and the surface of the mounting plate 100 is provided with a first through groove 203, and the end of the first connecting rod 202 passes through the first through groove 203 and extends to the lower side of the mounting plate 100, and the end of the first connecting rod 202 is rotatably installed with a second connecting rod 204, and the end of the second connecting rod 204 is connected to the lifting plate 106, and the bottom of the mounting plate 100 is connected to four limiting rods 205, and the lifting plate 106 is slidably installed on the four limiting rods 205, and the bottom of the two limiting rods 205 on one side are jointly installed with a bottom plate 206. When the shaft motor 105 is started, its output shaft drives the disc 201 to rotate, and the disc 201 drives the first connecting rod 202 to rise and fall. Since the two ends of the first connecting rod 202 are rotatably connected to the disc 201 and the second connecting rod 204 respectively, and the lifting plate 106 is limited by the four limiting rods 205, the lifting plate 106 can be driven to reciprocate in the vertical direction during the lifting and lowering of the first connecting rod 202. When the lifting plate 106 drops to the lowest point, it can drive the tamping plate 108 to tamp the road surface. Through the setting of the bottom plate 206, the two limiting rods 205 on one side can be connected into a whole, thereby improving the stability of its structure and improving its limiting effect on the lifting plate 106.

[0031] Specifically, the transmission mechanism 300 includes a second through groove 301 opened on the surface of the mounting plate 100, and a rotating shaft 302 is rotatably installed inside the second through groove 301. A first pulley group 303 is arranged for transmission between the output shaft of the dual-axis motor 105 and the rotating shaft 302, and a second pulley group 304 is arranged for transmission between the rotating shaft 302 and the connecting shaft 109. Through the transmission action of the first pulley group 303, when the dual-axis motor 105 is started, it can drive the rotating shaft 302 to rotate, and due to the transmission action of the second pulley group 304, the purpose of driving the connecting shaft 109 to rotate can be achieved. The connecting shaft 109 drives the moving wheels 104 at both ends thereof to rotate, thereby driving the entire device to move forward.

[0032] Specifically, two inclined rods 400 are installed on the outer surface of the mounting plate 100, and mounting blocks 401 are installed at the ends of the two inclined rods 400. A handrail 402 is provided between the two mounting blocks 401, and workers can control the forward direction of the device by holding the handrail 402.

[0033] Specifically, a slide bar 500 is installed inside the mounting block 401, and a slider 501 is slidably installed on the outer surface of the slide bar 500, and the two ends of the handrail 402 are respectively connected to the two sliders 501, and two springs 502 are sleeved on the outer surface of the slide bar 500, and the two springs 502 are respectively located on the upper and lower sides of the slider 501. Since the device can automatically move forward during the process of compacting the road surface, the contact between the hand and the handrail 402 can be reduced, and the strength of the hand holding the handrail 402 can be reduced. When the worker's hand holds the handrail 402, the slide bar 500 can effectively buffer the vibration generated by compacting the road surface, thereby reducing the force of the vibration on the hand and reducing discomfort.

[0034] Specifically, connecting grooves 600 are opened at the four corners of the upper surface of the tamping plate 108, and the connecting column 107 is inserted into the connecting groove 600. The outer surface of the connecting column 107 is opened with a screw hole 601. Four bolts 602 are installed on the outer surface of the tamping plate 108, and the bolts 602 are adapted to the screw holes 601. Through the setting of the connecting grooves 600, the screw holes 601 and the bolts 602, the tamping plate 108 can be conveniently replaced to meet different work requirements.

[0035] Specifically, storage boxes 700 are installed on the outer surfaces of the two second support columns 103. Through the arrangement of the storage boxes 700, workers can conveniently place items in the storage boxes 700, and heavy objects can also be placed in the storage boxes 700 to play a counterweight role and improve the stability of the device.

[0036] Specifically, a rubber pad 800 is provided on the outer surface of the armrest 402, and an anti-skid pattern is provided on the outer surface of the rubber pad 800. The provision of the rubber pad 800 can improve the comfort of the hand, increase the friction with the hand, and reduce the possibility of hand slippage.

[0037] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the utility model are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
