Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, specifically relating to a handheld road compactor for road engineering. Background Technology

[0002] Road engineering is a branch of civil engineering, mainly involving the planning, design, construction, maintenance, and management of roads. The research content of road engineering includes road network planning, route surveying and design, subgrade engineering, pavement engineering, road drainage engineering, bridge and culvert engineering, tunnel engineering, ancillary facilities engineering, and maintenance engineering. During road construction, compaction machines are used to impact and vibrate the roadbed or backfill soil to compact the subgrade.

[0003] Problems with existing technology:

[0004] Currently used handheld compactors mostly employ a single compaction plate that vibrates up and down in contact with the ground. As a result, during the compaction process, the single compaction plate not only has low compaction efficiency, but also requires the operator to hold the handheld compactor to maintain stability and move it, increasing the operator's burden and reducing the effectiveness of use. Utility Model Content

[0005] The purpose of this invention is to provide a handheld road compactor for road engineering that can solve the above-mentioned technical problems.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a handheld road compactor for road engineering, including a frame, a partition plate inside the frame, a compaction mechanism inside the frame, a fixed frame on the upper side of the outer periphery of the frame, a moving mechanism connected to the fixed frame on the outer periphery of the frame, a stabilizing plate on the upper surface of both the frame and the partition plate, a support plate on the stabilizing plate, a driving device on the support plate, and the driving device connected to the compaction mechanism.

[0008] The tamping mechanism includes two tamping plates, which are located on both sides of the partition plate inside the sleeve frame. The upper surface of the two tamping plates is provided with connecting plates. A balance shaft is rotatably mounted on multiple stabilizing plates. Two sets of symmetrical rotating plates are mounted on the balance shaft. A lifting mechanism is provided on each of the two sets of rotating plates. A pulley set is mounted on the balance shaft. The pulley set is connected to the rotating shaft on the drive device.

[0009] The moving mechanism includes a sliding frame that is slidably sleeved on the sleeve frame. The upper surface of the sliding frame is provided with push springs at the four corners. The lower surface of the fixed frame is fixedly connected to the four corners of the four push springs. The four corners of the sliding frame are provided with extension plates. The bottom surface of the extension plates is provided with moving wheels.

[0010] The above-mentioned handheld road compactor for road engineering is used. The drive device is started by switching on the switch. The drive device drives the pulley group on the compaction mechanism, which drives the balance shaft to rotate. At the same time, the balance shaft drives two sets of rotating plates to rotate. One set of rotating plates drives the lifting plate on the lifting mechanism to rise, and at the same time, it drives the corresponding compaction plate to move upward along the frame. Meanwhile, the other set of rotating plates drives the lifting plate on the lifting mechanism to move downward, thereby driving the corresponding compaction plate to move downward and smash the bottom surface to compact it. In this way, the two compaction plates can alternately compact the ground.

[0011] When moving, the brake lever on the moving mechanism can be rotated. The brake lever causes the clamping plate to rotate and release the jamming state. Then, the brake lever moves away from the sliding frame by the push of the rebound spring, which moves the push-pull plate and the two brake plates. This causes the brake plates to slide within the slide rail frame and disengage from the slots on the clamping plate, thus releasing the restriction on the sliding frame and allowing for sliding adjustment. At the same time, the moving wheels on the outer extension plate move up or down synchronously, providing support for the frame. Then, the brake lever is pushed towards the sliding frame, causing the clamping plate and push-pull plate to move synchronously. The push-pull plate causes the brake plate to engage in the corresponding slot on the clamping plate. Simultaneously, the brake lever compresses the rebound spring. Rotating the brake lever in the opposite direction causes the clamping plate to engage in the vertical hole on the slide rail, forming a jam. This allows the compactor to be moved and used.

[0012] Preferably, the lifting mechanism includes a lifting plate, with support shafts respectively provided on the upper and lower sides of the lifting plate. The upper support shaft is rotatably engaged with one of the rotating plates, and a buffer plate is sleeved on the connecting plate. The buffer plate is rotatably engaged with the lower support shaft.

[0013] Preferably, the sliding frame has recessed holes formed on opposite sides inside, and the recessed holes are slidably sleeved with two symmetrical slot plates set on opposite sides of the outer periphery of the sleeve frame. The sliding frame is provided with two slide rail frames, and brake plates are slidably arranged in the two slide rail frames respectively. The side of the slot plate is inserted and engaged with one side of the brake plate through multiple formed slots.

[0014] Preferably, a push-pull plate is provided horizontally on the outer periphery of the sliding frame, the push-pull plate is fixedly connected to the other side of the two brake plates, and a brake rod is rotatably provided on the push-pull plate.

[0015] Preferably, a sleeve is provided on the side of the sliding frame opposite to the push-pull plate, the brake rod is sleeved in the sleeve, a rebound spring is provided in the sleeve, and the rebound spring is fixedly connected to the side of the brake rod sleeved in the sleeve.

[0016] Preferably, the sleeve has a slide rail hole that communicates with the interior. The slide rail hole is L-shaped, and a retaining plate is fitted inside the slide rail hole. The retaining plate is located on the brake rod at the end inside the sleeve.

[0017] The beneficial effects are:

[0018] This invention utilizes two tamping plates on the tamping mechanism. These plates are driven by a lifting mechanism, and with the movement of two sets of rotating plates, they move in opposite directions, thus cyclically tamping the ground and improving tamping efficiency. Simultaneously, the movement wheels on the outer extension plate can be adjusted by the engagement of the brake plate and the slot plate on the moving mechanism. This allows for easy adjustment of the height of the moving wheels as needed, providing support for the tamping mechanism. As a result, the compactor can be moved easily, improving its practical application. Attached Figure Description

Detailed Implementation

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, a handheld road compactor for road engineering includes a frame 1, a partition plate inside the frame 1, a compaction mechanism 2 inside the frame 1, a fixed frame 6 on the upper side of the outer periphery of the frame 1, a moving mechanism 7 connected to the fixed frame 6 on the outer periphery of the frame 1, a stabilizing plate 3 on the upper surface of both the frame 1 and the partition plate, a support plate 5 on the stabilizing plate 3, a driving device 4 on the support plate 5, and the driving device 4 connected to the compaction mechanism 2.

[0028] The tamping mechanism 2 includes two tamping plates 201, which are located on both sides of the partition plate inside the frame 1. The upper surfaces of the two tamping plates 201 are respectively provided with connecting plates 202. A balance shaft 206 is rotatably mounted on multiple stabilizing plates 3. Two sets of symmetrical rotating plates 207 are mounted on the balance shaft 206. Each set of rotating plates 207 includes two plates mounted on the balance shaft 206. The positions on the balance shaft 206 and the rotating plates 207 are separated. The distance between the two rotating plates 207 in each set is greater than the width of the lifting plate 205, so as not to affect the upward movement of the lifting plate 205. A lifting mechanism is provided on each of the two sets of rotating plates 207. A pulley set 208 is provided on the balance shaft 206. The pulley set 208 is connected to the rotating shaft on the drive device 4. The drive device 4 is a motor, a gasoline engine, or a diesel engine. A switch 9 is installed on the side of one of the stabilizing plates 3. The output end of the switch 9 is electrically connected to the input end of the drive device 4.

[0029] The moving mechanism 7 includes a sliding frame 701 that is slidably sleeved on the sleeve frame 1. The upper surface of the sliding frame 701 is provided with four corners of a push spring 702. The lower surface of the fixed frame 6 is fixedly connected to the four corners of the four push springs 702. The four corners of the sliding frame 701 are provided with an extension plate 708. The bottom surface of the extension plate 708 is provided with a moving wheel.

[0030] As an optional implementation, the lifting mechanism includes a lifting plate 205, with support shafts 204 respectively provided on the upper and lower sides of the lifting plate 205. The upper support shaft 204 is rotatably engaged with one of the rotating plates 207. A buffer plate 203 is sleeved on the connecting plate 202, and the buffer plate 203 is rotatably engaged with the lower support shaft 204. The connecting plate 202 and the buffer plate 203 are designed in an n-shaped shape that slides and fits together. This allows the tamping plate 201 to make contact with the ground after tamping, and the connecting plate 202 and the buffer plate 203 form a sliding buffer, thereby reducing the stress transmission to the lifting plate 205.

[0031] See attached document Figure 4 The sliding frame 701 has recessed holes 703 formed on opposite sides inside. The recessed holes 703 are slidably sleeved with two symmetrical slot plates 8 set on opposite sides of the outer periphery of the sleeve frame 1. The sliding frame 701 is provided with two slide rail frames 704. Brake plates 705 are slidably arranged in the two slide rail frames 704 respectively. The side of the slot plate 8 is inserted and engaged with one side of the brake plate 705 through multiple formed slots. In this way, the brake plate 705 can restrict the sliding frame 701 after being inserted into the slot on the slot plate 8.

[0032] Furthermore, a push-pull plate 706 is horizontally provided on the outer periphery of the sliding frame 701. The push-pull plate 706 is fixedly connected to the other side of the two brake plates 705, and a brake rod 707 is rotatably provided on the push-pull plate 706.

[0033] See attached document Figure 5 A sleeve 709 is provided on the side of the sliding frame 701 opposite to the push-pull plate 706. The brake rod 707 is sleeved in the sleeve 709. A rebound spring 711 is provided in the sleeve 709. The rebound spring 711 is fixedly connected to the side of the brake rod 707 sleeved in the sleeve 709. This allows the rebound spring 711 to push the brake rod 707, thereby causing the brake rod 707 to slide along the sleeve 709 and drive the push-pull plate 706 and the brake plate 705 to release the jamming restriction on the sliding frame 701.

[0034] Furthermore, the sleeve 709 is formed with a slide rail hole 710 that communicates with the interior. The slide rail hole 710 is L-shaped, and a retaining plate 712 is fitted inside the slide rail hole 710. The retaining plate 712 is located at the end of the brake rod 707 inside the sleeve 709. The width of the upper part and the end of the slide rail hole 710 is greater than the width of the retaining plate 712, so that the retaining plate 712 can be moved and adjusted along the slide rail hole 710.

[0035] Using the above structure, the drive device 4 is started by the switch 9. The drive device 4 drives the pulley group 208 on the tamping mechanism 2, which drives the balance shaft 206 to rotate. At the same time, the balance shaft 206 drives the two sets of rotating plates 207 to rotate. One set of rotating plates 207 drives the lifting plate 205 on the lifting mechanism to rise, and at the same time drives the corresponding tamping plate 201 to move upward along the inside of the sleeve frame 1. Meanwhile, the other set of rotating plates 207 drives the lifting plate 205 on the lifting mechanism to move downward, thereby driving the corresponding tamping plate 201 to move downward and smash on the bottom surface to tamp and compact it. In this way, the two tamping plates 201 can present the effect of alternating tamping of the ground.

[0036] During movement, the brake lever 707 on the moving mechanism 7 can be rotated. The brake lever 707 drives the locking plate 712 to rotate and release the jamming state. Then, the brake lever 707 moves away from the sliding frame 701 by the push of the rebound spring 711. At the same time, it drives the push-pull plate 706 and the two brake plates 705 to move, so that the brake plates 705 slide in the slide rail frame 704 and disengage from the slot on the locking plate 8. This releases the restriction on the sliding frame 701, allowing the sliding frame 701 to be adjusted. At the same time, it drives the extension plate 7 The moving wheels on 08 move up or down synchronously, so that the moving wheels can move and support the sleeve frame 1. Then, the brake rod 707 is pushed to move towards the sliding frame 701, which drives the clamping plate 712 and the push-pull plate 706 to move synchronously. The push-pull plate 706 drives the brake plate 705 to be inserted into the corresponding groove on the clamping plate 8. At the same time, the brake rod 707 compresses the rebound spring 711. Then, the brake rod 707 is rotated in the opposite direction to drive the clamping plate 712 to be locked at the short part of the slide rail hole 710 to form a lock. In this way, the compactor can be moved and used.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
