Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 4 In an embodiment of the utility model, a deep foundation pit construction robot includes a robot chassis 1, a side surface of the robot chassis 1 is rotatably connected to a track wheel 101, an outer surface of the track wheel 101 is meshedly connected to a walking track 102, an upper surface of the robot chassis 1 is fixedly connected to a base 2, an upper surface of the base 2 is fixedly connected to a base rotary joint 201, an output end of the base rotary joint 201 is fixedly connected to a linear slide 202, an outer surface of the linear slide 202 is slidably connected to a slide 203, an outer surface of the slide 203 is fixedly connected to a limiting seat 204, an upper surface of the limiting seat 204 is fixedly connected to a hydraulic push rod 205, an output end of the hydraulic push rod 205 is fixedly connected to a limiting frame 206, and a mechanical clamp 207 is provided at the lower end of the limiting frame 206;

[0024] The upper surface of the robot chassis 1 is fixedly connected to the vertical plate 3, and the upper surface of the vertical plate 3 is provided with a monitoring mechanism 5, which includes a mounting seat 501, an electric push rod 504 and a camera 507. The mounting seat 501 is fixedly connected to the upper surface of the vertical plate 3, and the internal rotation of the mounting seat 501 is connected to the rotating shaft 502.

[0025] Specifically, when in use, the robot travels to the target working area at the bottom of the pit through the track wheels 101 and the walking track 102, and the base rotary joint 201 drives the linear slide 202 to rotate horizontally as a whole, so that the mechanical gripper 207 is aligned with the target to be grasped, and the hydraulic push rod 205 extends and retracts, pushing the limit frame 206 to rise and fall along the limit seat 204, and cooperating with the sliding of the slide 203 on the linear slide 202 to realize the vertical and horizontal positioning of the mechanical gripper 207. After the mechanical gripper 207 grasps the supporting component, the above steps are repeated to transport the target to the designated position through the robot chassis 1. In addition, the electric push rod 504 pushes the support frame 505 up and down, and drives the camera 507 to pitch through the N-shaped frame 506 to achieve multi-angle shooting. The rotating shaft 502 rotates at a low speed in the cabinet 503, so that the camera 507 can monitor 360° around, and the image and displacement data are transmitted back to the ground monitoring center in real time via the wireless module for remote analysis and early warning.

[0026] Example 1

[0027] like Figure 1-Figure 4 As shown, a first slide groove 301 is provided on the front surface of the vertical plate 3, a second slide groove 302 is provided on the front surface of the vertical plate 3, a stepper motor 305 is fixedly connected to the rear surface of the vertical plate 3, the output end of the stepper motor 305 is fixedly connected to a trapezoidal lead screw 306, the trapezoidal lead screw 306 and the vertical plate 3 are rotatably connected, the outer surface of the trapezoidal lead screw 306 is threadedly connected to a lead screw nut 303, and a bellows 304 is fixedly connected between the outer surface of the lead screw nut 303 and the vertical plate 3.

[0028] In this embodiment, the first slide groove 301 limits the movement of the lead screw nut 303, and the second slide groove 302 limits the movement of the mudguard 404. The stepper motor 305 is started, and the output end of the stepper motor 305 drives the trapezoidal lead screw 306 to rotate, thereby driving the lead screw nut 303 to move, and the bellows 304 provides dust protection for the trapezoidal lead screw 306.

[0029] like Figure 1-Figure 4 As shown, a mud scraping mechanism 4 is provided on the front surface of the vertical plate 3, and the mud scraping mechanism 4 includes a slide rail 401 and a connecting plate 403. The slide rail 401 is fixedly connected to the outer surface of the vertical plate 3, and the interior of the slide rail 401 is slidably connected to a rack 402, the rack 402 and the lead screw nut 303 are fixedly connected, the lead screw nut 303 and the first slide groove 301 are slidably connected, and the connecting plate 403 is fixedly connected to the lower surface of the rack 402, and the end of the connecting plate 403 is fixedly connected to a mud guard 404, one end of the mud guard 404 is fixedly connected to a driving motor 405, and the output end of the driving motor 405 is fixedly connected to a mud removal roller 406, and the outer surface of the mud removal roller 406 is fixedly connected to a spiral brush body 407, and the mud guard 404 is slidably connected to the second slide groove 302.

[0030] In this embodiment, after the robot travels a certain distance along the bottom of the foundation pit, a large amount of mud and sand will adhere to the surface of the walking track 102. At this time, the stepper motor 305 is started, and the stepper motor 305 drives the trapezoidal screw 306 to rotate. The screw nut 303 makes a linear reciprocating motion along the horizontally arranged second slide groove 302, and the rack 402 fixed to the screw nut 303 slides back and forth accordingly, driving the mud guard 404 to move synchronously in the horizontal direction through the connecting plate 403. During the movement of the mud guard 404, the drive motor 405 continues to operate, and the mud removal roller 406 drives the spiral brush body 407 to rotate at high speed.

When cleaning is not needed, the mud guard 404 can be retracted to the rear end of the track to avoid interference with the track, and the robot resumes normal driving operation.

[0031] Example 2

[0032] On the basis of the first embodiment, in order to make up for the problem in the first embodiment that it is inconvenient to adjust the horizontal angle of the monitoring mechanism 5 .

[0034] In this embodiment, the stud 803 is rotated so that the pressure claw 802 squeezes the damping sleeve 804 on the rotating shaft 502 under the push of the thread, reducing the possibility of the camera 507 being offset when the device moves. Driven by the rack 402, the gear 801 can drive the rotating shaft 502 to rotate, thereby deflecting the camera 507 and adjusting the monitoring range of the monitoring mechanism 5.

[0035] like Figure 1-Figure 4 As shown, the side surface of the cabinet 503 is embedded with a door body 6, and the door body 6 includes an inner door 601, a mounting block 603 and an outer door 606.

At this time, the door body 6 and the monitoring mechanism 5 can be separated, which is convenient for the later maintenance of the electrical components inside the cabinet 503. A double seal is formed when closed to prevent mud, dust and water vapor from entering the cabinet, thereby extending the life of the internal components. The control box 7 has a built-in PLC / motion control module, which uniformly drives the stepper motor 305, the drive motor 405, the electric push rod 504 and the base rotary joint 201 to achieve track cleaning, camera pitch, rotation, and control of the robot arm movement, as well as signal relay and wireless remote transmission. It integrates a wireless communication module to upload the image, displacement sensor data and motor status collected by the camera 507 to the ground monitoring center in real time and receive remote commands. This is the existing technology and no unnecessary elaboration is made in this article.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered illustrative and non-restrictive from all perspectives, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
