Description

Technical Field

[0001] The utility model relates to the technical field of compaction vehicles, in particular to a compaction vehicle for building foundations. Background Art

[0002] A foundation compactor, also known as a foundation compactor or foundation compaction equipment, is a type of engineering machinery used to compact the foundation. It usually consists of a heavy hammer and a chassis with a compaction plate. The compaction plate moves back and forth on the foundation and compacts the foundation through the gravity and vibration of the hammer. Foundation compactors are mainly used for foundation compaction operations in construction, road and bridge engineering. It can improve the density and stability of the foundation, enhance the bearing capacity of the foundation, and prevent the foundation from settling and deformation. Foundation compactors are generally suitable for various types of soil and geological conditions, including sand, clay and gravel. The operation of a foundation compactor is relatively simple, and the operator only needs to control the movement of the chassis and adjust the speed and strength of the compaction plate. However, due to the greater impact of the compactor on the foundation, reasonable adjustments and controls need to be made during operation according to specific engineering requirements and geological conditions to avoid adverse effects on the foundation.

[0003] When the existing compacting vehicle is in use, when the compacting block compacts the foundation, if it encounters some soil with high humidity, the soil may adhere to the surface of the compacting block after the compacting block compacts the soil. As the compacting block works repeatedly, the soil attached to the compacting block gradually thickens, thereby increasing the distance between the compacting block and the foundation, thereby relatively reducing the compacting strength of the compacting block on the foundation, thereby affecting the compacting effect of the compacting block.

DETAILED DESCRIPTION

[0030] like Figure 1-9 As shown, the utility model provides a technical solution: a compacting vehicle for building foundations, including a compacting vehicle 1, a mechanical arm 4 is arranged at the front end of the compacting vehicle 1, and a control unit 2 is arranged at the end of the mechanical arm 4 away from the compacting vehicle 1, and the control unit 2 includes: a linkage block 21, a shell 22, a motor bracket 23, a reciprocating motor 24, a rotating shaft 25, a compacting well 26, a protective cover 27, a guide plate 28, a support rod 29, a connecting rod 210, a rotating rod 211, a cleaning roller 212, an arc groove 213, a transmission tooth 214, a steel rope 215, a connecting buckle 216, a connecting block 217, a resistance block 218, a gear 219, and a compacting block 220.

[0031] The linkage block 21 is penetrated by the mechanical arm 4 and is hinged. The side of the linkage block 21 away from the mechanical arm 4 is fixedly connected to the housing 22. The surface of the housing 22 is fixedly connected to the motor bracket 23. The inner side of the motor bracket 23 is fixedly connected to the reciprocating motor 24. The output shaft of the reciprocating motor 24 is fixedly connected to the rotating shaft 25. The rotating shaft 25 penetrates the housing 22 and is rotatably connected. The top surface of the tamping well 26 is fixedly connected to the bottom surface of the housing 22. The outer surface of the tamping well 26 is fixedly connected to the protective cover 27. The inner wall of the tamping well 26 is fixedly connected to the guide plate 28. The support rod 29 penetrates the housing 22 and is fixedly connected. The support rod 29 penetrates and is rotatably connected to the connecting rod 210. When the rotating shaft 25 contracts the steel rope 215 After reaching a certain extent, the reciprocating motor 24 starts to rotate. At this time, the resistance block 218 resists the raised part of the connecting rod 210 for the second time, so that the connecting rod 210 is stretched open. While the reciprocating motor 24 causes the tamping block 220 to tamp back and forth, the driving force of the arc spring 33 can ensure that when the cleaning roller 212 is reset, the brush can stably clean the soil on the surface of the tamping block 220. The bottom end of the connecting rod 210 is penetrated and rotatably connected by the rotating rod 211. The rotating rod 211 penetrates and is fixedly connected with the cleaning roller 212.

The reciprocating motor 24 is started. When the reciprocating motor 24 is started, the output shaft of the reciprocating motor 24 will drive the rotating shaft 25 to rotate. When the rotating shaft 25 rotates, the steel rope 215 will be wound around the rotating shaft 25, so that the steel rope 215 will pull up the compacting block 220 through the connecting buckle 216 and the connecting block 217.

When the rotating rod 211 rotates around the support rod 29, the slider 34 will be driven to slide together, and the slider 34 will slide along the arc-shaped rod 32. At the same time, the slider 34 will compress the arc spring 33. When the contact block 218 opens the connecting rod 210, it will be embedded in the recess in the middle of the connecting rod 210, so that the compressed arc spring 33 pushes the slider 34 to reset, and the slider 34 will drive the rotating rod 211 to slide together. At this time, the rotating rod 211 rotates around the support rod 29 as a fulcrum, and a through hole 35 is opened on the surface of the slider 34. The through hole 35 is penetrated and slidably connected by the arc-shaped rod 32. An arc spring 33 is fixedly connected to the surface of the slider 34, and one end of the arc spring 33 away from the slider 34 is fixedly connected to the inner wall of the shell 22. The arc rod 32 penetrates the shell 22 and is fixedly connected. The gear 219 will drive the rotating rod 211 to rotate again, and then the rotating rod 211 drives the cleaning roller 212 to rotate again, and the cleaning roller 212 will move to the bottom of the tamping block 220, so that the brush on the surface of the cleaning roller 212 can beat and clean the soil attached to the bottom of the tamping block 220, preventing too much soil from adhering to the tamping block 220, thereby reducing the tamping strength of the foundation, and ensuring the tamping effect of the tamping block 220. The surface of the cleaning roller 212 is provided with a cleaning brush. When the gear 219 rotates around the center of the support rod 29, it will slide along the arc groove 213, and the gear 219 will rotate through the transmission tooth 214, and the gear 219 will drive the rotating rod 211 to rotate, so that the brush on the surface of the cleaning roller 212 cleans the soil attached to the side when the tamping block 220 is tamped. There are four connecting rods 210 in two groups, and each two groups of connecting rods 210 are symmetrically arranged with the center line of the housing 22 as the symmetry axis. The gear 219 meshes with the transmission tooth 214, and when the abutment block 218 rises, it will gradually abut the middle protruding part of the connecting rod 210, so that the connecting rod 210 rotates with the center point of the support rod 29 as the axis, thereby driving the rotating rod 211 to rotate together, and the rotating rod 211 will drive the cleaning roller 212 and the gear 219 to rotate together.

[0033] Based on the above-mentioned factual method, by moving the compacting vehicle 1 to the front of the foundation to be compacted, the compacting well 26 is brought into contact with the foundation through the mechanical arm 4 and the linkage block 21, and the reciprocating motor 24 is started. When the reciprocating motor 24 is started, the output shaft of the reciprocating motor 24 drives the rotating shaft 25 to rotate, and the rotating shaft 25 will reel the steel rope 215 on the rotating shaft 25 when rotating, so that the steel rope 215 pulls up the compacting block 220 through the connecting buckle 216 and the connecting block 217, and when the connecting block 217 is raised, it will drive the resistance block When the abutment block 218 is raised, it gradually abuts against the middle raised part of the connecting rod 210, so that the connecting rod 210 rotates with the center point of the supporting rod 29 as the axis, thereby driving the rotating rod 211 to rotate together, and the rotating rod 211 drives the cleaning roller 212 and the gear 219 to rotate together. When the gear 219 rotates around the center of the supporting rod 29, it slides along the arc groove 213, and the gear 219 is rotated through the transmission tooth 214, and the gear 219 drives the rotating rod 211 When the rotating rod 211 rotates around the supporting rod 29, the slider 34 will slide together, and the slider 34 will slide along the arc rod 32. At the same time, the slider 34 will compress the arc spring 33. When the contact block 218 opens the connecting rod 210, it will be embedded in the depression in the middle of the connecting rod 210, so that the compressed arc spring 33 pushes the slider 34 to reset, and the slider 34 will bring The movable rotating rod 211 slides together, and the rotating rod 211 rotates with the support rod 29 as the fulcrum. At the same time, the gear 219 will drive the rotating rod 211 to rotate again, and then the rotating rod 211 drives the cleaning roller 212 to rotate again, and the cleaning roller 212 will move to the bottom of the tamping block 220, so that the brush on the surface of the cleaning roller 212 can beat and clean the soil attached to the bottom of the tamping block 220, preventing too much soil from adhering to the tamping block 220, thereby reducing the tamping strength of the foundation, and ensuring the tamping effect of the tamping block 220.

[0034] When the rotating shaft 25 shrinks the steel rope 215 to a certain extent, the reciprocating motor 24 starts to rotate. At this time, the resistance block 218 resists the raised part of the connecting rod 210 for the second time, so that the connecting rod 210 is stretched open. While the reciprocating motor 24 causes the tamping block 220 to tamp back and forth, the driving force of the arc spring 33 can ensure that when the cleaning roller 212 is reset, the brush can stably clean the soil on the surface of the tamping block 220.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
