Description

Technical Field

[0001] The utility model relates to the technical field of runway tamping, in particular to a portable tamping device used for runway construction. Background Art

[0002] Runway construction is a complex engineering project involving multiple stages and technical requirements. The key steps of runway construction include design planning, material selection, construction and quality monitoring. Some traffic intersections or schools now build runways to provide better roads. When the runway is constructed, gravel is usually needed for paving, and some gravel varies in size. Now during runway construction, due to the uneven arrangement of gravel, some gravel on the entire runway is uneven, so the gravel needs to be tamped and compacted to better pave the runway.

[0003] For example, Chinese patent CN211079832U discloses a portable tamping device for runway construction. By using an adjustment component, the distance between the first adjustment rod and the second adjustment rod can be adjusted, and the first adjustment rod and the second adjustment rod are fixed with an adjustment bolt, so that the angle between the first tamping bracket and the second tamping bracket can be adjusted. The gravel can be tamped flat, making the runway surface smoother and more stable, and improving the tamping efficiency to a certain extent. By using the connecting component, the angle of the first tamping bracket and the second tamping bracket can be better adjusted by adjusting the first connecting rod and the second connecting rod, which greatly improves the tamping effect of the gravel and improves the service life of the tamping device to a certain extent.

[0004] Although the tamping angle can be adjusted for this structure, the operator tamps the device manually, resulting in uneven tamping force and affecting the overall flatness of the runway. Therefore, we propose a portable tamping device for runway construction that can evenly apply pressure to an uneven runway to make the tamping flatness more consistent. Utility Model Content

[0005] The purpose of the present utility model is to provide a portable tamping device for runway construction to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a portable tamping device for runway construction, comprising a body, an outer wall of the body being hingedly connected to a telescopic rod, an end of the telescopic rod being hingedly connected to a gantry, and a processing assembly arranged outside the body, the processing assembly including a tamping assembly arranged outside the body, and an adjustment assembly being arranged below the tamping assembly.

[0007] Preferably, the tamping assembly includes a bracket fixedly mounted on the top surface of the gantry, a motor is fixedly mounted on the outer wall of the bracket, a rotating rod is fixedly mounted on the output end of the motor, an incomplete gear is fixedly mounted on the outer wall of the rotating rod, a baffle is fixedly mounted on the side wall of the incomplete gear, the incomplete gear is meshed with a rack, the end of the rotating rod away from the motor is rotatably connected to a support plate, a fixed block is fixedly mounted on the outer wall of the gantry, a limiting rod is slidingly provided inside the fixed block, and a push plate is fixedly mounted on the end of the limiting rod.

[0008] Preferably, the adjustment assembly includes a support plate fixedly mounted on the outer wall of the push plate, a screw is sleeved inside the support plate, the end of the screw is rotatably connected to a frame, a tamping plate is fixedly mounted on the end of the frame, a limit frame is slidingly arranged inside the frame, and a limit ring is fixedly mounted on the end of the limit frame.

[0009] Preferably, the incomplete gear is a gear with few teeth, and the side wall of the baffle is slidingly arranged with the outer wall of the rack. Under the restriction of the incomplete gear, when the incomplete gear is not engaged with the rack, the rack can fall naturally under the action of gravity. Under the restriction of the baffle, the incomplete gear can be engaged more accurately without deviation.

[0010] Preferably, the end of the rack is fixedly mounted to the top surface of the push plate, and there are two racks, which are symmetrically distributed about the center line of the push plate. Under their restriction, the push plate can be lifted. When the rack is no longer engaged with the incomplete gear, the push plate is dropped to drive the tamping plate to perform tamping work.

[0011] Preferably, the end of the limit frame is fixedly installed with the outer wall of the push plate. There are two limit frames, which are symmetrically distributed with respect to the center line of the frame. Under the restriction of the limit frame, the screw can drive the frame to slide stably.

[0012] Preferably, the screw and the support plate are threadedly sleeved, and the end of the screw is rotatably connected to the top surface of the frame. Under the restriction of the limit frame, the rotating screw can adjust the position of the tamping plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The portable tamping device for runway construction is composed of a tamping assembly as one component. When the runway is uneven, it needs to be leveled. At this time, the motor is started, and the rotating rod fixedly installed at its output end rotates accordingly, and the incomplete gear sleeved on the outer wall of the rotating rod rotates accordingly. The incomplete gear drives the rack engaged with it to move, so that the rack drives the push plate to move upward, and the limit rod fixedly installed on the top surface of the push plate slides inside the fixed block. Under the restriction of the fixed block, the push plate can move upward more stably. When the incomplete gear rotates to a state where it no longer engages with the rack, under the action of gravity, the push plate drives the rack and the limit rod to move downward, so that the tamping plate arranged on the outer wall of the push plate contacts and tamps the ground to level it. The device enables the operator to start the vehicle body to conveniently level the runway, and the leveling force is uniform, so that the runway foundation is flat and consistent.

[0015] 2. The portable tamping device for runway construction is composed of an adjustment component as one of its components. When different pressures need to be applied, the screw is rotated. Since the frame and the outer wall of the limit frame are slidingly arranged, and the end of the screw is rotatably connected to the top surface of the frame, under its restriction, the rotating screw can drive the frame to move upward, so that the frame drives the tamping plate to move upward. When the incomplete gear lifts the rack, the distance between the tamping plate and the ground can be increased, and its falling height can be increased. Then, the freely falling tamping plate can apply greater pressure to increase the tamping force, so that the tamping plate can achieve different tamping effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] And a processing component 4 is arranged on the outside of the vehicle body 1, the processing component 4 includes a tamping component 41 arranged on the outside of the vehicle body 1, the tamping component 41 includes a bracket 411 fixedly installed on the top surface of the door frame 3, the outer wall of the bracket 411 is fixedly installed with a motor 412, the output end of the motor 412 is fixedly installed with a rotating rod 413, the outer wall of the rotating rod 413 is fixedly installed with an incomplete gear 414, the side wall of the incomplete gear 414 is fixedly installed with a baffle 415, the incomplete gear 414 is meshed with a rack 416, the end of the rotating rod 413 away from the motor 412 is rotatably connected to a support plate 417, the outer wall of the door frame 3 is fixedly installed with a fixed block 420, the fixed block 420 is slidingly provided with a limit rod 419, and the end of the limit rod 419 is fixedly installed with a push plate 418.

[0028] In this embodiment, when the runway is uneven and needs to be leveled, the motor 412 is started, and the rotating rod 413 fixedly installed at its output end rotates accordingly, and the incomplete gear 414 sleeved on the outer wall of the rotating rod 413 rotates accordingly, and the incomplete gear 414 drives the rack 416 meshed with it to move, so that the rack 416 drives the push plate 418 to move upward, and the limit rod 419 fixedly installed on the top surface of the push plate 418 slides inside the fixed block 420, and is restricted by the fixed block 420. , the push plate 418 can move upward more stably. When the incomplete gear 414 rotates to a state where it no longer meshes with the rack 416, under the action of gravity, the push plate 418 drives the rack 416 and the limit rod 419 to move downward, so that the tamping plate 434 provided on the outer wall of the push plate 418 contacts and tamps the ground to level it. This device allows the operator to start the vehicle body 1 to conveniently level the runway, and the leveling force is uniform, so that the runway foundation is flat and consistent.

[0029] Furthermore, the incomplete gear 414 is a gear with few teeth, and the side wall of the baffle 415 is slidingly arranged with the outer wall of the rack 416. Under the restriction of the incomplete gear 414, when the incomplete gear 414 is not engaged with the rack 416, the rack 416 can fall naturally under the action of gravity. Under the restriction of the baffle 415, the incomplete gear 414 can be engaged more accurately without deviation.

There are two racks 416, which are symmetrically distributed about the center line of the push plate 418. Under its limitation, the push plate 418 can be lifted. When the rack 416 no longer engages with the incomplete gear 414, the push plate 418 falls to drive the tamping plate 434 to perform tamping work.

When the incomplete gear 414 lifts the rack 416, the distance between the tamping plate 434 and the ground can be increased, and its falling height can be increased. Then, the freely falling tamping plate 434 can apply greater pressure to increase the tamping force, so that the tamping plate 434 can achieve different tamping effects.

[0033] Furthermore, the end of the limit frame 435 is fixedly installed with the outer wall of the push plate 418. There are two limit frames 435, which are symmetrically distributed with respect to the center line of the frame 433. Under the restriction of the limit frame 435, the screw 432 can drive the frame 433 to slide stably.
