Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a split-type excavation robot for deep foundation pit operations used in foundation construction. Background Art

[0002] In the construction of power grid transmission lines, the excavation of foundation pits is undoubtedly an indispensable part of the construction. How to complete the excavation of foundation pits with high efficiency and quality in the process of power grid construction is the research direction of the power grid industry. In the traditional excavation of foundation pits for wireline construction, there are generally two types of construction methods. One is the hole-making method in which construction personnel enter the foundation hole to work. During construction, the workers use shovels or electric pickaxes to break the ground, which is labor-intensive. The construction efficiency is low. It usually takes 6-7 days to complete the excavation of a foundation pit, which is troublesome and laborious. When working in the pit manually, there are risks of suffocation, falling objects from high altitude, and foundation pit collapse, which are very dangerous. Therefore, problems such as these are more inclined to pile hole foundation operations in which construction personnel do not enter the foundation hole to work.

[0003] Pile hole foundations where construction workers do not enter the foundation hole are generally excavated by rotary machines. However, rotary excavation has the following problems: The existing small and medium-sized rotary drilling rigs have small hole diameters: Most drilling rigs have relatively small hole diameters, while the pile hole diameters required by current engineering construction are getting larger and larger, so general small and medium-sized rotary drilling rigs cannot meet the requirements of engineering pile hole construction. During the construction process, as the rotary hole deepens, it needs to be disassembled continuously, reducing work efficiency. And the soil generated by excavation is difficult to discharge outward.

[0004] Therefore, in view of the difficulties in on-site construction, a split-type excavation robot for deep foundation pit operations for foundation construction is proposed to solve the above problems. Summary of the invention

The corrugated plate on the driving drum can loosen the surrounding soil and transport it to the middle of the first rotating disk under the action of rotation. The soil transported to the middle of the first rotating disk will fall into the space excavated by the excavation drill below. In the circular groove of the excavation drill, the excavation drum driven to rotate by the first motor can move the soil upward. Finally, the excavation drum can move the excavated soil to its upper end and drop it into the surrounding lifting cylinder. After absorbing enough soil, the lifting cylinder can be lifted to lift the soil from the excavation robot to complete the transportation of the soil.

[0018] When the second motor is working, it can drive the first rotating disk to rotate in the process of driving the roller to dig the soil without additional power. At the same time, the transmission mechanism can drive the drill body at the lower end to rotate when the first rotating disk rotates, which can reduce the number of motors driving the drill body to rotate, reduce the overall weight and thus reduce costs.

The transverse hydraulic rod 12 supports the support plate 13 to the inner wall of the foundation pit, which can fix the first equipment compartment 3 and the second equipment compartment 7.

[0031] The support plates 13 are all in an arc shape, and a plurality of fixing bars 14 are fixedly connected to the outer side of the support plates 13, and the plurality of fixing bars 14 are equidistantly arranged in the vertical direction. A connection block 15 is fixedly connected to one end of the support plate 13 close to the transverse hydraulic rod 12, and the support plate 13 is fixedly connected to the transverse hydraulic rod 12 through the connection block 15. The fixing bars 14 can be inserted into the soil to increase the supporting force obtained by the support plate 13 through the foundation pit wall.

The lower end of the transmission mechanism 9 is meshedly connected to a plurality of second linkage teeth 17, and the second linkage teeth 17 are equidistantly distributed on the inner wall of the excavation drill bit 10.

[0033] The transmission mechanism 9 includes a plurality of first gears 18, wherein the first gear 18 is meshed with the first linkage tooth 16, wherein a transmission shaft 19 is fixedly connected to the first gear 18, wherein the lower end of the transmission shaft 19 is fixedly connected with a second gear 20, wherein the second gear 20 is meshed with the second linkage tooth 17, wherein the upper end of the first gear 18 and the lower end of the second gear 20 are both rotatably connected with a positioning block 21, wherein the positioning block 21 at the upper end of the first gear 18 is fixedly connected with the inner wall of the circular through hole of the second equipment compartment 7, and the positioning block 21 at the lower end of the second gear 20 is fixedly connected with the inner wall of the excavation drill bit 10.

When the first gear 18 rotates, it can drive the transmission shaft 19 to rotate, and the transmission shaft 19 can drive the second gear 20 at the lower end to rotate. Since the positioning block 21 at the upper end of the first gear 18 is fixedly connected to the inner wall of the circular through hole of the second equipment compartment 7, and the positioning block 21 at the lower end of the second gear 20 is fixedly connected to the inner wall of the excavation drill bit 10, the second gear 20 can drive the piercing linkage tooth to rotate and move.

[0035] The first rotating disk 8 is provided with a slide groove 25 , and a first limiting ring 26 is rotatably connected in the slide groove 25 of the first rotating disk 8 . The first limiting ring 26 is fixedly connected to the bottom surface of the second equipment compartment 7 .

A corrugated plate 32 is fixedly connected to the outer surface of the driving roller 31 .

[0037] A first motor 28 is fixedly connected to the inner wall of the circular through hole of the lower support mechanism 5, and an excavation drum 29 is fixedly connected to the output end of the first motor 28. The lower end of the excavation drum 29 penetrates into the circular groove 24 of the drill bit. The lower end of the drum penetrates into the circular groove 24 of the drill bit to carry the soil excavated by the drill bit upward.

[0038] The excavation drill bit 10 includes a connecting plate 22, the inner wall of which is fixedly connected to the second linkage tooth 17, a drill body 23 is provided at the lower end of the connecting plate 22, and a circular groove 24 is provided in the middle of the drill body 23. The second linkage tooth 17 rotates under the drive of the second gear 20, so that the connecting plate 22 fixedly connected to the second linkage tooth 17 can rotate.

[0039] A lifting cylinder 33 is provided on both sides of the first motor 28. The upper opening height of the lifting cylinder 33 is lower than the upper end height of the digging drum 29. The upper surface of the lifting cylinder 33 is fixedly connected with a pulling rope 27. When the digging drum 29 digs out the soil, it will fall into the lifting cylinder 33, which is convenient for the lifting cylinder 33 to rise and lift the soil out.

[0040] When the excavation robot is needed, an initial foundation pit is first excavated on the ground, and then the upper support mechanism 1 is lifted by a crane and dropped into the initial foundation pit. Then the transverse hydraulic rods 12 in the upper support mechanism 1 and the lower support mechanism 5 extend outward, connecting the support plate 13 with the inner wall of the initial skill, playing a supporting and fixing role. Then the second motor 30 starts to operate, driving the drive roller 31 and the excavation drill bit 10 to rotate for excavation.

[0041] When the second motor 30 is working, it can drive the first rotating disk 8 to rotate in the process of driving the roller 31 to dig the soil. At the same time, the transmission mechanism 9 can drive the drill body 23 at the lower end to rotate when the first rotating disk 8 rotates. When the first gear 18 moves, it will rotate under the drive of the first linkage tooth 16. When the first gear 18 rotates, it can drive the transmission shaft 19 to rotate, and the transmission shaft 19 can drive the second gear 20 at the lower end to rotate. Since the positioning block 21 at the upper end of the first gear 18 is fixedly connected to the inner wall of the circular through hole of the second equipment compartment 7, and the positioning block 21 at the lower end of the second gear 20 is fixedly connected to the inner wall of the excavation drill bit 10, the second gear 20 can drive the piercing linkage tooth to rotate and move. The second linkage tooth 17 rotates under the drive of the second gear 20, which can cause the connecting disk 22 fixedly connected to the second linkage tooth 17 to rotate.

[0042] When the excavation robot needs to move downward to dig deeper, the movement can be completed by relying on the vertical hydraulic press 4 between the upper support mechanism 1 and the lower support mechanism 5. First, the transverse hydraulic support rod in the lower support mechanism 5 is retracted inward, and then the vertical hydraulic press 4 is extended downward to push the lower support mechanism 5 downward. After the lower support mechanism 5 moves downward into position, the transverse hydraulic support rod in the lower support mechanism 5 extends outward, so that the lower support mechanism 5 can be fixed on the inner wall of the foundation pit. After the lower support mechanism 5 is fixed, the transverse hydraulic support rod of the upper support mechanism 1 is retracted inward, and at the same time, the vertical hydraulic press (4) is retracted downward, driving the upper support mechanism 1 to move downward, thereby achieving the effect of moving the excavation robot as a whole downward.

[0043] During excavation, the second motor 30 below the first rotating disk 8 can drive the driving drum 31 to rotate, and the corrugated plate 32 on the driving drum 31 can loosen the surrounding soil and transport it to the middle of the first rotating disk 8 under the action of rotation. The soil transported to the middle of the first rotating disk 8 will fall into the space excavated by the excavation drill bit 10 below. In the circular groove 24 of the excavation drill bit 10, the excavation drum 29 driven to rotate by the first motor 28 can move the soil upward. Finally, the excavation drum 29 can move the excavated soil to its upper end and drop it into the surrounding lifting cylinder 33. After receiving enough soil, the lifting cylinder 33 can be lifted to lift the soil from the excavation robot to complete the transportation of the soil.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
