Description

Technical Field

[0001] The invention relates to the technical field of civil engineering construction auxiliary equipment, and in particular to a foundation compacting equipment for civil engineering. Background Art

[0002] During the construction of civil engineering, it is often necessary to compact the foundation. There are many types of compaction equipment in the prior art. For example, the Chinese patent with patent application number: CN202023258802.2 discloses a foundation compaction device for civil engineering. This patent uses a lifting column to drive the compaction base to reciprocate to compact the soil layer. However, during operation, the compaction position is fixed. When compacting a large area of ​​soil, manpower is required to frequently transfer the device, which will result in high labor intensity and low work efficiency. Secondly, when compacting the soil layer, the bottom of the compaction base is prone to adhere to mud. Therefore, during the compaction process, it is necessary to frequently remove the adhered soil, which increases the workload.

[0003] A Chinese patent with patent application number: CN202021823654.1 discloses a foundation compaction device for civil engineering. This patent adjusts the compaction position by moving a slider inside a slide groove, but when it is working, it is still necessary to manually adjust the position of the hydraulic compaction machine body, and the position of the device as a whole cannot be adjusted. After the soil layer at the device as a whole is compacted, the device as a whole needs to be moved; this patent also cleans the weight through a pressure nozzle, but when cleaning the weight, it is first necessary to move the position of the weight, and then start the water pump to clean the weight, and the equipment needs to be shut down, that is, this patent cannot simultaneously clean the compacted component (weight) during the compaction process. When the weight is cleaned with water, the soil at the compaction position will become more moist, and it is inconvenient to compact moist soil. Summary of the invention

The horizontal portion 2181 is provided on the upper roller surface of the driving roller 23. One end of the horizontal portion 2181 is connected to the top of the vertical portion 2182. The other end of the horizontal portion 2181 is connected to the vertical portion 2182 through the spiral portion 2183. 2 is docked at the bottom, the head of the driving rod 214 is inserted into the driving groove 218, the right side of the mounting seat 1 is fixedly connected with a connecting shaft 24 through a pair of ear seats, the connecting shaft 24 is fixedly connected with a first driving bevel gear 219 meshing with the first driven bevel gear 217, the front end of the connecting shaft 24 is fixedly connected with a transmission wheel 220, the first motor 25 is fixedly connected to the top of the mounting seat 1, the output shaft head of the first motor 25 is fixedly connected with a driving wheel 221, and the driving wheel 221 and the transmission wheel 220 are linked by a belt 222 Looking from top to bottom, the first motor 25 drives the driving roller 23 to rotate counterclockwise; When the head of the driving rod 214 is located in the spiral portion 2183, the ramming plate 22 is in the power storage stage, at which time the ramming plate 22 rises; when the head of the driving rod 214 is located in the horizontal portion 2181, the ramming plate 22 is in the holding stage, at which time the height of the ramming plate 22 remains unchanged; when the head of the driving rod 214 is located in the vertical portion 2182, the ramming plate 22 is in the compacting stage, at which time the ramming plate 22 rapidly descends; When the tamping plate 22 is in the holding stage, the traveling device and the soil removing device are started. The traveling device is used to drive the equipment to move, and the soil removing device is used to remove the soil adhered to the bottom of the tamping plate 22.

[0021] Preferably, a handle 13 is fixedly connected to the left side of the mounting base 1, a triangular reinforcing rib plate 14 is fixedly connected between the mounting base 1 and the first supporting bin 11 and the second supporting bin 12, the driving groove 218 is T-shaped, and a disc 223 is fixedly connected to the head of the driving rod 214, and the disc 223 is engaged with the bottom of the driving groove 218; the diameter of the driving wheel 221 is larger than the diameter of the transmission wheel 220.

[0022] Preferably, when the head of the driving rod 214 is located in the horizontal part 2181, the lifting plate 21 contacts the top surface of the lifting groove 27, and at this time the ramming plate 22 enters the storage groove, and the bottom surface of the ramming plate 22 is flush with the bottom surface of the mounting seat 1; when the head of the driving rod 214 is located at the bottom of the vertical part 2182, the lifting plate 21 contacts the bottom surface of the lifting groove 27.

[0023] In this embodiment:

[0024] When the equipment moves to the position that needs to be compacted, the first motor 25 is started, and the first motor 25 drives the driving wheel 221 to rotate. The driving wheel 221 drives the transmission wheel 220 to rotate through the belt 222, so that the connecting shaft 24 and the first active bevel gear 219 fixed thereon rotate, and the first active bevel gear 219 drives the first driven bevel gear 217 meshing therewith to rotate, so that the driving roller 23 rotates. The diameter of the driving wheel 221 is larger than the diameter of the transmission wheel 220, so that the rotation speed of the transmission wheel 220 can be reduced and the torque can be increased.

[0025] like Fig.12 As shown, when the driving roller 23 rotates counterclockwise, the driving groove 218 arranged on its roller surface rotates, and the driving rod 214 slides in the driving groove 218, so that the height of the driving rod 214 changes, and then the height of the guide plate 213 and the lifting plate 21 changes, and the lifting plate 21 changes the height of the tamping plate 22 through the support rod 210.

[0026] Since the driving groove 218 is T-shaped, the disk 223 at the head of the driving rod 214 is engaged with the bottom of the driving groove 218, which can avoid the separation of the driving rod 214 and the driving roller 23. When the driving roller 23 rotates counterclockwise, the driving rod 214 circulates through the horizontal portion 2181, the vertical portion 2182 and the spiral portion 2183. When the driving rod 214 slides in the horizontal portion 2181, the height of the ramming plate 22 remains unchanged. When the driving rod 214 moves to the top of the vertical portion 2182, under the action of the release spring 29, the ramming plate 22 drops rapidly. When the driving rod 214 moves in the spiral portion 2183, the height of the ramming plate 22 continues to rise.

[0027] like Figure 6As shown, when the driving rod 214 is located in the horizontal portion 2181, the lifting plate 21 contacts the top surface of the lifting groove 27, the ramming plate 22 enters the storage groove, the lower surface of the ramming plate 22 is flush with the bottom surface of the mounting base 1, and the release spring 29 is in a compressed state. At this time, the walking device and the soil removing device are started, the walking device is used to drive the equipment to move, and the soil removing device is used to remove the soil adhered to the bottom of the ramming plate 22.

[0028] like Figure 8 As shown, when the driving rod 214 moves to the top of the vertical portion 2182, the compressed release spring 29 extends, and the driving rod 214 quickly drops in the vertical portion 2182, so that the lifting plate 21 moves to the bottom of the lifting slot 27, and the tamping plate 22 quickly drops to compact the ground.

[0029] The driving rod 214 enters the spiral portion 2183 from the bottom of the vertical portion 2182 and rises in the spiral portion 2183 . At this time, the lifting plate 21 and the ramming plate 22 rise, and the ramming plate 22 accumulates force.

[0030] like Figure 3 As shown, the tamping plate 22 cyclically switches between the power storage stage, the holding stage and the compaction stage. In the holding stage of the tamping plate 22, the walking device works to move the equipment, and the soil removing device works to remove the soil adhering to the bottom of the tamping plate 22.

[0031] As a further implementation method of this embodiment, the support rod 210 is slidably connected to the lifting plate 21, and the top of each support rod 210 is fixedly connected to the limit plate 224. The upper surface of the lifting plate 21 is provided with a retractable groove 225 corresponding to the limit plate 224. When the lifting plate 21 contacts the top surface of the lifting groove 27, the limit plate 224 enters the retractable groove 225. Assuming the height difference between the lifting plate 21 and the lifting groove 27 is a, and the distance between the bottom surface of the mounting seat 1 and the ground is b, then a>b.

[0032] In this embodiment: like Figure 6 and 8 As shown, in order to allow the ramming plate 22 to fully and accurately contact the ground to be compacted, a>b is set. In the compacting stage of the ramming plate 22, the extension of the release spring 29 cooperates with the gravity of the lifting plate 21 to make the lifting plate 21 drop rapidly. The ramming plate 22 drops rapidly under the action of gravity to compact the ground. When the lifting plate 21 moves to the bottom of the lifting groove 27, the top of the support rod 210 extends above the lifting plate 21 to ensure that the ramming plate 22 can contact the ground.

[0033] During the power accumulation stage of the ramming plate 22 , the lifting plate 21 rises first, and when the limiting plate 224 enters the receiving and releasing groove 225 , the lifting plate 21 pulls the ramming plate 22 to rise through the supporting rod 210 . Example 2

[0034] In this embodiment, a circuit system in a device is disclosed, so that various devices in the device can accurately cooperate with each other and the device can switch between various working states.

[0035] The walking device and the soil removing device are driven by the second motor 61. An electric control device 5 is provided at the upper left corner of one of the lifting slots 27. When the lifting plate 21 contacts the top surface of the lifting slot 27, the electric control device 5 is turned on. A battery 62, a main control switch 63, a first switch 64 and a second switch 65 are fixedly connected to the top of the mounting base 1; The positive pole of the battery 62 is electrically connected to the positive terminal of the first motor 25 and the second motor 61 through the main control switch 63; the negative terminal of the first motor 25 is electrically connected to the negative pole of the battery 62 through the first switch 64; the negative terminal of the second motor 61 is electrically connected to the negative pole of the battery 62 through the electronic control device 5 and the second switch 65 connected in parallel.

[0036] In this embodiment: This device has the following three working states: Standby state: Fig. 9 As shown, at this time, the main control switch 63 is in an open circuit state, and the first motor 25 and the second motor 61 are not powered.

[0037] Working status: Fig.10 As shown, at this time, the main control switch 63 and the first switch 64 are in the on state, and the second switch 65 is in the off state. When the equipment is working, the first motor 25 drives the tamping plate 22 to move for compaction operation. When the lifting plate 21 contacts the top surface of the lifting groove 27, the second motor 61 works, and the walking device and the soil removing device work. The equipment automatically cycles to achieve compaction, movement and soil removing operations.

[0038] Transfer status: Fig.11 As shown, the main control switch 63 and the second switch 65 are in the on state, and the first switch 64 is in the off state. At this time, the first motor 25 is braked, and the ramming plate 22 does not work, thereby preventing the ramming plate 22 from interfering with the movement of the equipment. The second motor 61 continues to work, and the walking device enables the equipment to move continuously, thereby realizing the transfer of the equipment, and the operation of the soil removing device does not interfere with the transfer of the equipment.

[0041] In this embodiment: like Figure 6 and 7 As shown, when the lifting plate 21 contacts the top surface of the lifting groove 27, the lifting plate 21 causes the lifting plate 510 to enter the avoidance groove 57. At the same time, the supporting plate 51 and the power connection plate 52 rise synchronously, and the power connection plate 52 contacts the two power connection blocks 53. The circuit between the two power connection blocks 53 is turned on, that is, the electric control device 5 is turned on.
