Description

Technical Field

[0001] This utility model relates to the field of plate compaction technology, and in particular to a vertical plate compactor. Background Technology

[0002] A plate compactor, as a small engineering machine, works by using high-frequency vibration to compact loose materials such as soil, gravel, and asphalt. Its basic operation involves using a power unit such as an internal combustion engine or electric motor to drive a vibrating mechanism, generating continuous high-frequency vibration. This vibrational energy is then transferred to the material being compacted through a rigid compaction plate at the bottom. Under the action of vibration, material particles move closer together and fill the gaps, thereby increasing the density and overall stability of the material, ultimately reducing foundation settlement and enhancing the structural bearing capacity. Currently, most plate compactors on the market are equipped with long handrails, making them well-suited for use in relatively open environments with few obstacles.

[0003] However, the inventors discovered that the long handrails of this plate compactor cause numerous problems when used in confined spaces. Firstly, the long handrails make it difficult for the plate compactor to turn in narrow spaces; secondly, the handrails easily interfere with surrounding obstacles, significantly reducing operational convenience. Furthermore, the plate compactor generates strong vibrations during operation, which are easily transmitted to the handrails, causing numbness in the operator's hands and severely impacting operational comfort. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a vertical plate compactor, which improves the convenience of operation, reduces the vibration transmitted to the handrail end, and enhances the comfort of operation.

[0005] To solve the above-mentioned technical problems, the present invention provides a vertical plate compactor, comprising: a compaction plate, an eccentric mechanism, a belt, and a rotary drive device. The rotary drive device is connected to the eccentric mechanism via the belt. The eccentric mechanism is mounted on the compaction plate. An upper cover is provided above the eccentric mechanism. Two inclined damping components are symmetrically connected between one end of the lower surface of the upper cover and the compaction plate, and two first horizontal damping components are symmetrically connected between the other end of the lower surface of the upper cover and the compaction plate, which are suitable for attenuating vibrations in the left and right directions.

[0006] An operating armrest mechanism is provided above the top cover. The operating armrest mechanism includes a front support and a rear support that are symmetrically inclined. The two ends of the bottom of the front support are respectively connected to the top cover with a second horizontal shock-absorbing component, which is suitable for attenuating vibrations in the front-to-back direction. The two ends of the bottom of the rear support are respectively connected to the top cover with a third horizontal shock-absorbing component, which is suitable for attenuating vibrations in the left-to-right direction.

[0007] By adopting the above technical solution, when in use, after the rotary drive device is started, the eccentric mechanism is driven by the belt. The high-frequency vibration generated by the eccentric mechanism is transmitted to the material being compacted through the tamping plate. Under the action of vibration, the material particles move closer to each other and fill the gaps, thereby improving the density and overall stability of the material, and ultimately achieving the effect of reducing foundation settlement and enhancing the structural bearing capacity.

[0008] To effectively reduce vibration transmission, this plate compactor employs a multi-stage vibration damping design: two inclined damping components are connected between the top cover and the compaction plate, absorbing some of the inclined vibration energy transmitted from the compaction plate to the top cover; two first horizontal damping components are also connected between the top cover and the compaction plate, absorbing some of the left-right vibration energy transmitted from the compaction plate to the top cover. Furthermore, a second horizontal damping component connected between the front support and the top cover absorbs some of the front-rear vibration energy transmitted from the top cover to the front support; a third horizontal damping component connected between the rear support and the top cover absorbs some of the left-right vibration energy transmitted from the top cover to the rear support. Through the synergistic effect of these damping components, the front-rear, left-right vibration energy transmitted from the top cover to the operating handle mechanism is significantly reduced, significantly enhancing operational comfort. Simultaneously, in confined working environments, because the operating handle mechanism is located above the top cover, the turning radius for workers is effectively reduced, lowering the probability of interference between the plate compactor and surrounding obstacles, further improving operational convenience.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the inclined damping component includes an upper inclined support and a lower inclined support disposed below it, an inclined rubber damping block is connected between the upper inclined support and the lower inclined support, an inclined screw is inserted through the center of the inclined rubber damping block, one end of the inclined screw passes through the upper inclined support and is helically connected to a nut, the other end passes through the lower inclined support and is helically connected to a nut, the upper end of the upper inclined support is connected to the upper cover, and the lower end of the lower inclined support is connected to the tamping plate.

[0010] By adopting the above technical solution, the tilting damping component uses the cooperation of tilting screws and nuts to fix the tilting rubber damping block between the upper and lower tilting supports. Utilizing the elastic properties of the tilting rubber damping block, it can absorb some of the tilting vibration energy transmitted from the lower tilting support to the upper tilting support, further improving the overall damping effect.

[0011] In a preferred embodiment, the present invention can be further configured such that: the two side walls of the upper cover are respectively provided with U-shaped opening slots; the first horizontal shock absorption component includes an L-shaped fixing seat, a first horizontal shock absorption block and a first screw; the first screw is inserted through the center of the first horizontal shock absorption block; one end of the first screw passes through the L-shaped fixing seat and is helically connected to a nut; and the other end passes through the U-shaped opening slot and is helically connected to a nut.

[0012] By adopting the above technical solution, the first horizontal damping component, through the cooperation of the first screw and nut, fixes the first horizontal damping block between the L-shaped fixing seat and the side wall of the upper cover. Utilizing the elastic characteristics of the first horizontal damping block, it can absorb some of the lateral vibration energy transmitted from the L-shaped fixing seat to the upper cover, thus improving the overall damping effect.

[0013] In a preferred embodiment, the present invention can be further configured such that: the second horizontal damping component includes a second horizontal damping block, a second screw, and a vertical fixing seat connected to the top of the upper cover; the second screw passes through the center of the second horizontal damping block; one end of the second screw passes through the front bracket and is screwed with a nut; and the other end passes through the vertical fixing seat and is screwed with a nut.

[0014] By adopting the above technical solution, the second horizontal damping component, through the cooperation of the second screw and nut, fixes the second horizontal damping block between the vertical mounting base and the front bracket. Utilizing the elastic properties of the second horizontal damping block, it can absorb some of the front-rear vibration energy transmitted from the vertical mounting base to the front bracket, thereby improving the overall damping effect.

[0015] In a preferred embodiment, the present invention can be further configured such that the third horizontal damping component includes a U-shaped fixing seat, a third horizontal damping block, and a third screw passing through the third horizontal damping block. One end of the third screw passes through the rear bracket and is helically connected to a nut, and the other end passes through the U-shaped fixing seat and is helically connected to a nut.

[0016] By adopting the above technical solution, the third horizontal damping component, through the cooperation of the third screw and nut, fixes the third horizontal damping block between the U-shaped fixing seat and the rear bracket. Utilizing the elastic properties of the third horizontal damping block, it can absorb some of the lateral vibration energy transmitted from the U-shaped fixing seat to the rear bracket, thus improving the overall damping effect.

[0017] In a preferred embodiment, this utility model can be further configured as follows: two U-shaped seats are connected at intervals at one end of the ramming plate near the inclined damping component. The outer side of the U-shaped seat is provided with a mounting hole, and the inner side is provided with a clearance hole and a limiting hole. The inner diameter of the clearance hole is larger than the inner diameter of the limiting hole and they are connected. Two fixed cylinder assemblies are symmetrically connected on the front bracket. Roller assemblies are respectively inserted through the inner holes of the fixed cylinder assemblies. The roller assembly includes a support shaft and a roller body rotatably connected to one end thereto. The outer circle of the other end of the support shaft is provided with an annular groove and passes through the inner hole of the fixed cylinder assembly. A fixing nut is connected to the fixed cylinder assembly. A limiting screw is spirally inserted into the fixing nut. The threaded end of the limiting screw passes through the fixed cylinder assembly and extends into the annular groove.

[0018] The fixed cylinder assembly includes a first ear plate and a second ear plate that are spaced apart and connected to the front bracket. Both the first ear plate and the second ear plate are provided with circular through holes. A first round tube is connected between the first ear plate and the second ear plate. A second round tube, which is concentric with the first round tube, is connected to the side of the second ear plate away from the first round tube. The first round tube is provided with an inner liner tube that is adapted to the outer circle of the support shaft. The outer circle of the second round tube is connected to the fixing nut.

[0019] By adopting the above technical solution, the support shaft of the roller assembly passes through the inner hole of the fixed cylinder assembly, and the annular groove on the support shaft is located inside the second circular tube. Since the limiting screw and the fixing nut are threadedly connected, rotating the limiting screw so that its end extends into the annular groove can prevent the support shaft from moving axially, thus achieving the limiting effect. At the same time, by setting an inner liner tube inside the first circular tube, allowing the support shaft to pass through the inner hole of the inner liner tube and match it, the shaking generated when the roller assembly moves is effectively reduced. After construction, if it is necessary to move the vertical plate compactor, the limiting screw can be rotated in the opposite direction to remove the roller assembly. Then, one end of the support shaft on the roller assembly is passed through the mounting hole and clearance hole on the U-shaped seat in sequence, so that the roller body contacts the ground. Under the gravity of the vertical plate compactor, the support shaft tilts, causing the annular groove on the support shaft to engage with the inner wall of the limiting hole, thereby preventing the support shaft of the roller assembly from detaching from the mounting hole. With the help of the roller body, the vertical plate compactor can be easily moved, greatly improving the convenience of operation.

[0020] In a preferred embodiment, the present invention can be further configured such that the operating armrest mechanism also includes a rectangular frame and a V-shaped handle connected to its upper plane, wherein the rectangular frame is connected to the upper oblique ends of the front support and the rear support respectively.

[0021] By adopting the above technical solution, the rectangular frame and V-shaped handle work together to facilitate construction personnel in controlling the turning direction of the vertical plate compactor.

[0022] In a preferred embodiment, the present invention can be further configured such that U-shaped protective plates are connected to the front and rear sides of the front and rear supports, respectively.

[0023] By adopting the above technical solution and using U-shaped protective plates, construction workers are prevented from touching the rotating drive device, thus improving construction safety.

[0024] In summary, this utility model has at least one of the following beneficial technical effects:

[0025] 1. By cooperating with the inclined damping components, the first horizontal damping components, the second horizontal damping components and the third horizontal damping components, the vibration transmitted from the ramming plate to the operating handrail mechanism along the front, back, left, right and inclined directions is greatly reduced, thus improving the comfort of operation.

[0026] 2. The operating handle is located above the top cover, which reduces the turning radius in narrow environments, reduces the probability of interference with obstacles, and improves the ease of operation. Attached Figure Description

[0044] Reference Figures 1-5 This utility model discloses a vertical plate compactor, comprising: a compaction plate 1, an eccentric mechanism 2, a belt 11, and a rotary drive device 12. The rotary drive device 12 is a gasoline engine. The rotary drive device 12 is connected to the eccentric mechanism 2 via the belt 11. The eccentric mechanism 2 is mounted on the compaction plate 1. An upper cover 13 is provided above the eccentric mechanism 2. Two inclined damping components 30 are symmetrically connected between one end of the lower surface of the upper cover 13 and the compaction plate 1, and two first horizontal damping components 40 are symmetrically connected between the other end of the lower surface of the upper cover 13 and the compaction plate 1, which are suitable for attenuating vibrations in the left and right directions.

[0045] The tilting damping assembly 30 includes an upper tilting support 31 and a lower tilting support 32 disposed below it. A tilting rubber damping block 33 is connected between the upper tilting support 31 and the lower tilting support 32.

The tilting damping assembly 30 fixes the tilting rubber damping block 33 between the upper tilting support 31 and the lower tilting support 32 through the cooperation of the tilting screw 34 and the nut. Utilizing the elastic properties of the tilting rubber damping block 33, it can absorb part of the tilting vibration energy transmitted from the lower tilting support 32 to the upper tilting support 31, further improving the overall damping effect.

[0046] The two side walls of the top cover 13 are respectively provided with U-shaped opening slots 14. The first horizontal shock absorption assembly 40 includes an L-shaped fixing seat 41, a first horizontal shock absorption block 42, and a first screw 43. The first horizontal shock absorption block 42 is made of rubber, and the first screw 43 passes through the center of the first horizontal shock absorption block 42. One end of the first screw 43 passes through the L-shaped fixing seat 41 and is screwed to a nut, and the other end passes through the U-shaped opening slot 14 and is screwed to a nut. The first horizontal shock absorption assembly 40 fixes the first horizontal shock absorption block 42 between the L-shaped fixing seat 41 and the side wall of the top cover 13 through the cooperation of the first screw 43 and the nut. With the help of the elastic characteristics of the first horizontal shock absorption block 42, it can absorb part of the lateral vibration energy transmitted from the L-shaped fixing seat 41 to the top cover 13, thereby improving the overall shock absorption effect.

[0047] An operating armrest mechanism 50 is provided above the top cover 13. The operating armrest mechanism 50 includes a front support 51 and a rear support 52 that are symmetrically inclined. The two ends of the bottom of the front support 51 are respectively connected to the top cover 13 with a second horizontal shock absorption component 60, which is suitable for attenuating vibrations in the front-to-back direction. The two ends of the bottom of the rear support 52 are respectively connected to the top cover 13 with a third horizontal shock absorption component 70, which is suitable for attenuating vibrations in the left-to-right direction.

[0048] The second horizontal damping assembly 60 includes a second horizontal damping block 61, a second screw 62, and a vertical fixing seat 63 connected to the top of the upper cover 13. The second horizontal damping block 61 is made of rubber. The second screw 62 passes through the center of the second horizontal damping block 61. One end of the second screw 62 passes through the front bracket 51 and is screwed with a nut, while the other end passes through the vertical fixing seat 63 and is screwed with a nut. The second horizontal damping assembly 60, through the cooperation of the second screw 62 and the nut, fixes the second horizontal damping block 61 between the vertical fixing seat 63 and the front bracket 51. Utilizing the elastic properties of the second horizontal damping block 61, it can absorb some of the front-to-back vibration energy transmitted from the vertical fixing seat 63 to the front bracket 51, thus improving the overall damping effect.

[0049] The third horizontal damping component 70 includes a U-shaped mounting base 71, a third horizontal damping block 72, and a third screw 73 passing through the third horizontal damping block 72. The third horizontal damping block 72 is made of rubber. One end of the third screw 73 passes through the rear bracket 52 and is screwed to a nut, while the other end passes through the U-shaped mounting base 71 and is screwed to a nut. The third horizontal damping component 70, through the cooperation of the third screw 73 and the nut, fixes the third horizontal damping block 72 between the U-shaped mounting base 71 and the rear bracket 52. Utilizing the elastic properties of the third horizontal damping block 72, it can absorb some of the lateral vibration energy transmitted from the U-shaped mounting base 71 to the rear bracket 52, thus improving the overall damping effect.

[0050] Two U-shaped seats 15 are connected at intervals on one end of the ramming plate 1 near the inclined damping component 30. The outer side of each U-shaped seat 15 has a mounting hole 16, and the inner side has a clearance hole 17 and a limiting hole 18. The inner diameter of the clearance hole 17 is larger than the inner diameter of the limiting hole 18 and they are connected. Two fixed cylinder assemblies 80 are symmetrically connected to the front bracket 51. Roller assemblies 90 are respectively installed through the inner holes of the fixed cylinder assemblies 80. Each roller assembly 90 includes a support shaft 91 and a roller body 92 rotatably connected to one end. The other end of the support shaft 91 has an annular groove 93 on its outer circumference and passes through the inner hole of the fixed cylinder assembly 80. A fixing nut 1 is connected to the fixed cylinder assembly 80. 9. A limiting screw 21 is spirally threaded through the fixing nut 19. The threaded end of the limiting screw 21 passes through the fixing cylinder assembly 80 and extends into the annular groove 93. The fixing cylinder assembly 80 includes a first ear plate 81 and a second ear plate 82 spaced apart and connected to the front bracket 51. Both the first ear plate 81 and the second ear plate 82 are provided with circular through holes 83. A first round tube 84 is connected between the first ear plate 81 and the second ear plate 82. A second round tube 85, concentric with the first round tube 84, is connected to the side of the second ear plate 82 away from the first round tube 84. The first round tube 84 is provided with an inner liner tube 86 adapted to the outer circle of the support shaft 91. The fixing nut 19 is connected to the outer circle surface of the second round tube 85. The support shaft 91 of the roller assembly 90 passes through the inner hole of the fixing cylinder assembly 80, and the annular groove 93 on the support shaft 91 is located inside the second round tube 85. Since the limiting screw 21 and the fixing nut 19 are threadedly connected, rotating the limiting screw 21 so that its end extends into the annular groove 93 can prevent the support shaft 91 from moving axially, thus achieving a limiting effect. Simultaneously, by setting an inner liner 86 inside the circular tube 84, allowing the support shaft 91 to pass through and match the inner hole of the inner liner 86, the shaking generated when the roller assembly 90 moves is effectively reduced. After construction, if it is necessary to move the vertical plate compactor, the limiting screw 21 can be rotated in the opposite direction to remove the roller assembly 90. Then, one end of the support shaft 91 on the roller assembly 90 is sequentially passed through the mounting hole 16 and the clearance hole 17 on the U-shaped seat 15, so that the roller body 92 contacts the ground. Under the gravity of the vertical plate compactor, the support shaft 91 tilts, causing the annular groove 93 on the support shaft 91 to engage with the inner wall of the limiting hole 18, thereby preventing the support shaft 91 of the roller assembly 90 from detaching from the mounting hole 16. With the help of roller body 92, the vertical plate compactor can be easily moved, which greatly improves the convenience of operation.

[0051] The operating handle mechanism 50 also includes a rectangular frame 53 and a V-shaped handle 54 connected to its upper surface. The rectangular frame 53 is connected to the upper inclined ends of the front support 51 and the rear support 52, respectively. Through the cooperation of the rectangular frame 53 and the V-shaped handle 54, it is convenient for construction personnel to control the turning direction of the vertical plate compactor.

[0052] U-shaped protective plates 22 are connected to the front and rear sides of the front support 51 and the rear support 52, respectively. The use of U-shaped protective plates 22 prevents construction personnel from touching the rotating drive device 12, thereby improving construction safety.

[0053] The implementation principle of this embodiment is as follows: When in use, after the rotary drive device 12 is started, it drives the eccentric mechanism 2 to operate through the belt 11. The high-frequency vibration generated by the eccentric mechanism 2 is transmitted to the material being compacted through the tamping plate 1. Under the action of vibration, the material particles move closer to each other and fill the gaps, thereby improving the density and overall stability of the material, and ultimately achieving the effect of reducing foundation settlement and enhancing the structural bearing capacity.

[0054] To effectively reduce vibration transmission, the plate compactor employs a multi-stage vibration damping design: two inclined damping components 30 are connected between the upper cover 13 and the compaction plate 1, absorbing some of the inclined vibration energy transmitted from the compaction plate 1 to the upper cover 13; two first horizontal damping components 40 are also connected between the upper cover 13 and the compaction plate 1, absorbing some of the left-right vibration energy transmitted from the compaction plate 1 to the upper cover 13. Furthermore, a second horizontal damping component 60 connected between the front support 51 and the upper cover 13 absorbs some of the front-rear vibration energy transmitted from the upper cover 13 to the front support 51; a third horizontal damping component 70 connected between the rear support 52 and the upper cover 13 absorbs some of the left-right vibration energy transmitted from the upper cover 13 to the rear support 52. Through the synergistic effect of these damping components, the vibration energy transmitted from the upper cover 13 to the operating handle mechanism 50 in the front, rear, left, and right directions is significantly reduced, greatly enhancing operational comfort. Meanwhile, in confined working environments, the operating handrail mechanism 50, located above the upper cover 13, effectively reduces the turning radius for workers during construction, lowers the probability of the plate compactor interfering with surrounding obstacles, and further improves the ease of operation.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
