Technical Field

[0001] The embodiment of the utility model relates to the technical field of building construction, and in particular to a foundation trench excavation device. Background Art

[0002] At present, when constructing a ground foundation with a bottom spiral ground nail, it is usually necessary to dig a circular foundation trench on the concrete ground to fit the bottom spiral ground nail. The size of the circular foundation trench is usually 0.3m deep and 0.42m in diameter. In addition, during construction, it is usually necessary to dig a circular foundation trench every 3m. When the entire construction line is not less than 30 kilometers, it is necessary to dig no less than 10,000 circular foundation trenches.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0028] Reference Figure 1 to Figure 2 As shown, this embodiment provides a foundation trench excavation device, including an excavation device body 1, a mechanical arm assembly 2 and a trench excavation structure 3.

[0029] The excavation equipment body 1 is used to be set on the ground where a trench is to be dug and is rotatably connected to one end of the mechanical arm assembly 2 , and the trenching structure 3 is set at the other end of the mechanical arm assembly 2 .

[0030] The side of the trenching structure 3 facing away from the mechanical arm assembly 2 is formed as an open structure 31, and when the excavation equipment body 1 drives the mechanical arm assembly 2 to rotate and / or lift, the trenching structure 3 can be driven to remove part of the soil at the ground to be trenched to form a foundation trench on the ground to be trenched.

[0031] When implementing it, refer to Figure 1 and Figure 2 As shown, the excavation equipment body 1 itself can be the equipment body of an existing excavator, and the mechanical arm assembly 2 itself can be the mechanical arm of an existing excavator. Therefore, this embodiment does not describe in detail the specific structure of the excavation equipment body 1 and the specific structure of the mechanical arm assembly 2.

[0032] Specifically, when trenching construction is required, the excavation equipment body 1 can be moved to the ground to be trenched where construction is required, and then the excavation equipment body 1 can drive the mechanical arm assembly 2 to move. The action, for example, is to only drive the mechanical arm assembly 2 to rotate. At this time, the mechanical arm assembly 2 rotates and drives the trenching structure 3 to perform rotational cutting, thereby cutting off part of the soil in the ground to be trenched, or only drive the mechanical arm assembly 2 to rise and fall to drive the trenching structure 3 to dig downward from the ground to be trenched or drive the trenching structure 3 to move the excavated soil out of the ground to be trenched; or the mechanical arm can be driven to rotate and rise at the same time, thereby driving the trenching structure 3 to dig downward and perform rotational cutting at the same time, thereby cutting off part of the soil and then moving it out of the ground to be trenched, thereby forming a foundation trench on the ground to be trenched.

[0033] Exemplarily, the robot arm assembly 2 may include at least two robot arms 21 rotatably connected to each other. Figure 1 As shown, the robot arm assembly 2 may include three sections of the robot arm 21, or in other implementations, the robot arm assembly 2 may also include two sections of the robot arm 21, or include more than three sections of the robot arm 21. Specifically, the number of robot arms 21 may be set according to actual needs, and this embodiment does not specifically limit this.

[0034] The foundation trench excavation equipment provided in this embodiment includes an excavation equipment body 1, a mechanical arm assembly 2, and a trenching structure 3. The excavation equipment body 1 is used to be set on the ground to be trenched and is rotatably connected to one end of the mechanical arm assembly 2, and the trenching structure 3 is set at the other end of the mechanical arm assembly 2. The side of the trenching structure 3 that is away from the mechanical arm assembly 2 is formed as an open structure 31, and when the excavation equipment body 1 drives the mechanical arm assembly 2 to rotate and / or lift, it can drive the trenching structure 3 to excavate part of the soil at the ground to be trenched, so as to form a foundation trench on the ground to be trenched. In other words, the foundation trench excavation equipment of this embodiment can drive the mechanical arm assembly 2 to perform corresponding actions through the excavation equipment body 1, thereby driving the trenching structure 3 connected to the mechanical arm assembly 2 to perform soil excavation operations, thereby forming a foundation trench on the ground to be trenched, so that automatic trenching operations can be realized, which not only saves time and effort, but also has good consistency in the size of the foundation trench formed by the same trenching structure 3, which is conducive to improving the construction effect.

[0035] Reference Figure 1 and Figure 2 As shown, in some embodiments, the grooving structure 3 includes a grooving cylinder 32 , a side of the grooving cylinder 32 close to the robot arm assembly 2 is connected to the robot arm assembly 2 , and the open structure 31 is arranged on a side of the grooving cylinder 32 away from the robot arm assembly 2 .

[0036] When implementing it, refer to Figure 2 In the up-down direction shown, the side of the trenching cylinder 32 close to the mechanical arm assembly 2 is set as the upper surface of the trenching cylinder 32, and the side of the trenching cylinder 32 away from the mechanical arm assembly 2 is set as the lower surface of the trenching cylinder 32. At this time, it can be considered that the upper surface of the trenching cylinder 32 is connected to the mechanical arm, and the lower surface of the trenching cylinder 32 is an open structure 31, so that when the trenching cylinder 32 is driven by the mechanical arm assembly 2 to dig downward, when the soil is moderately soft, part of the soil can enter the trenching cylinder 32 through the open structure 31 and then be taken out by the trenching cylinder 32. At this time, a base trench of a preset shape can be directly formed on the ground to be trenched, without secondary cleaning of the soil, thereby further simplifying the construction operation and improving the construction efficiency.

[0037] For example, the cross section of the groove cylinder 32 may be circular, and the base groove formed in this case is a circular base groove. Alternatively, in other implementations, the cross section of the groove cylinder 32 may be square, and a square base groove may be formed in this case. The specific shape of the groove cylinder 32 may be determined according to the shape of the base groove to be formed.

[0038] Reference Figure 2As shown, in some embodiments, the grooved cylinder 32 includes a cylinder side wall 321 and a cylinder top wall 322 connected to the cylinder side wall 321 , and the cylinder side wall 321 is respectively provided with openings at both ends along the axial direction of the grooved cylinder 32 .

[0040] When implementing it, refer to Figure 2 In the up and down direction shown, the cylinder top wall 322 can be set above the cylinder side wall 321. At this time, the opening at the top of the cylinder side wall 321 is covered and sealed by the cylinder top wall 322, and the opening at the bottom of the cylinder side wall 321 is formed into an open structure 31 for soil to enter.

[0041] Specifically, when the grooved cylinder 32 includes a cylinder side wall 321 and a cylinder top wall 322 , in order to facilitate connection, the cylinder top wall 322 may be provided to be connected to the robot arm assembly 2 .

[0042] Exemplarily, the cylinder top wall 322 and the cylinder side wall 321 may be integrally formed to save manufacturing steps and improve the structural strength of the entire grooved cylinder 32 .

[0043] In addition, the trenching cylinder 32 can be made of metal or alloy so that it has sufficient structural strength and hardness to facilitate excavation of soil.

[0045] In some embodiments, a first connecting hole is provided on the connecting member 4, and a second connecting hole is provided on the robotic arm assembly 2 at a position corresponding to the first connecting hole. The connecting member 4 is connected to the robotic arm assembly 2 by fasteners passed through the first connecting hole and the second connecting hole, thereby achieving a reliable connection between the connecting member 4 and the robotic arm assembly 2.

[0046] For example, the first connection hole and the second connection hole may both be threaded holes, in which case the fastener may be a bolt or a screw that matches the threaded hole. Alternatively, in other implementations, the first connection hole and the second connection hole may both be plain holes, in which case the fastener may be a fastening pin that matches the plain hole.

[0047] In addition, there may be multiple first connection holes and second connection holes in one-to-one correspondence, so that the connection stability between the connector 4 and the robotic arm assembly 2 can be further improved through the coordination of multiple first connection holes and second connection holes.

[0048] Reference Figure 2 As shown, in some embodiments, the connecting member 4 includes at least two connecting plates 41, and the at least two connecting plates 41 are arranged at radial intervals along the groove cylinder 32, and each connecting plate 41 is provided with a first connecting hole, so that it can be connected to the robot arm assembly 2 through at least two connecting plates 41 to further improve the connection stability between the connecting member 4 and the robot arm assembly 2.

[0049] Exemplarily, the connecting member 4 may include two connecting plates 41 , or may include three or more connecting plates 41 .

[0050] Exemplarily, the connecting plate 41 may be a steel plate, or an iron plate, etc.

[0051] Reference Figure 2 As shown, in some embodiments, the connecting plate 41 includes a first plate body 411 and a second plate body 412 connected to the first plate body 411, the first plate body 411 is connected to the cylinder top wall 322 and extends radially along the groove cylinder 32, the second plate body 412 is connected to the robot arm assembly 2, and the second plate body 412 extends axially along the groove cylinder 32.

[0052] That is, in order to facilitate the connection and assembly of the connecting plate 41 with the cylinder top wall 322 and the robot arm assembly 2, the connecting plate 41 can be provided to include a first plate body 411 and a second plate body 412 vertically arranged, so that the connecting plate 41 as a whole is as follows: Figure 2 The L-shaped structure shown.

[0053] In some embodiments, the first plate 411 is connected to the top wall 322 of the cylinder by welding, so as to simplify the connection operation and improve the reliability and stability of the connection between the two.

[0054] Exemplarily, the first plate body 411 and the second plate body 412 are integrally formed, which can not only save manufacturing steps but also improve the overall structural strength of the connecting plate 41 .

[0055] In some embodiments, the inner diameter of the groove cylinder 32 ranges from 400 mm to 600 mm, so that a base groove of a desired size can be formed by properly setting the inner diameter of the groove cylinder 32 .

[0056] For example, the inner diameter of the grooved cylinder 32 may be 400 mm, or may be other sizes such as 500 mm or 600 mm.

[0057] In some embodiments, the dimension of the groove cylinder 32 along the axial direction of the groove cylinder 32 ranges from 300 mm to 500 mm. By properly setting the dimension of the groove cylinder 32 along its axial direction, a base groove of a desired dimension can be formed.

[0058] Exemplarily, the axial dimension of the grooved cylinder 32 may be 300 mm, or may be other dimensions such as 400 mm or 500 mm.

[0059] In this embodiment, in order to form a circular base groove with a depth of 300 mm and a diameter of 420 mm, the cross-section of the groove cylinder 32 can be set to be circular, the inner diameter of the groove cylinder 32 can be 420 mm, and the axial dimension of the groove cylinder 32 can be 300 mm.
