Description

Technical Field

[0001] This utility model belongs to the field of trenching equipment, specifically relating to a trenching device for building retaining walls. Background Technology

[0002] In retaining wall construction, trench excavation is a crucial preliminary step, and its quality directly affects the structural stability of the subsequent retaining wall. Currently, the trenching equipment used in this step mostly adopts conventional mechanical structures and is equipped with basic excavation components such as buckets and booms. The excavation action is usually driven by simple power transmission systems such as hydraulic devices. Some equipment also has a basic walking mechanism to adapt to different construction sites.

[0003] These existing devices rely primarily on the operator's experience during operation, using visual observation and manual operation to control the excavation direction and approximate depth. However, in trenching operations for retaining wall construction, these devices are clearly inadequate. Trenching equipment typically lacks a structure and mechanism specifically designed for measuring trench height, making it difficult to conveniently and accurately measure the height within the trench in real time during excavation. This results in inconsistencies in the height within the trench after excavation, making it difficult to ensure the consistency of the excavation depth. Utility Model Content

[0004] To overcome the problem that existing trenching equipment lacks a dedicated trench height measurement structure and mechanism in retaining wall construction, which makes it impossible to measure the height inside the trench in real time and accurately, resulting in inconsistent heights inside the trench after excavation and difficulty in ensuring consistent excavation depth, a trenching equipment for retaining wall construction is proposed.

[0005] The technical solution of this utility model is as follows: a trenching device for building a retaining wall, comprising a bearing plate, a support body fixed to the lower end of the bearing plate, rollers rotatably installed on both sides of the support body, a first bracket fixed to the upper end of the bearing plate, an octagonal body fixed to the upper end of the first bracket, cameras fixed to each side wall of the octagonal body, a trenching mechanism fixed to the first bracket, a driving mechanism set on the trenching mechanism, a first fixing block fixed to the bearing plate, two second limiting grooves opened on the upper end of the bearing plate and a first limiting groove opened on the four side walls of the bearing plate, at least two sliding blocks are slidably provided on the inner wall of the first limiting groove, a U-shaped block is fixedly connected to the end of the sliding block away from the bearing plate, a limiting post is fixedly connected to the upper end of the sliding block, the side wall of the limiting post is slidably provided on the inner wall of the second limiting groove, a rotating frame is hinged on the U-shaped block, a height measuring mechanism is inserted into the rotating frame, and a control mechanism is provided on the first bracket;

[0006] The upper end of the support plate has at least four insertion holes for placing the height measuring mechanism;

[0007] A locking mechanism is inserted on the rotating frame. When two rotating frames on different sides and corresponding to each other approach each other, the locking mechanism is used to lock the two rotating frames.

[0008] Furthermore, the trenching mechanism includes an inclined block fixed to one side of the first support, a rotating arm rotatably connected to the inclined block, a turntable rotatably connected to the upper end of the rotating arm, multiple cutting heads fixed to the side wall of the turntable, a second support fixed to the upper end of the rotating arm, and a cylinder hinged to the lower end of the rotating arm, with the output end of the cylinder hinged to the lower end of the inclined block.

[0009] Furthermore, the drive mechanism includes a third bracket fixed to the upper end of the second bracket, a motor fixed to the upper end of the third bracket, and a first pulley and a transmission belt rotatably mounted on the upper end of the second bracket. The output shaft of the motor passes through the third bracket and is fixed to the shaft of the first pulley. A transmission belt is provided on the side wall of the first pulley. The first pulley and the second pulley are rotatably connected by the transmission belt. The lower end of the shaft of the second pulley passes through the second bracket and is fixed to the shaft of the turntable.

[0010] Furthermore, the height measuring mechanism includes a height measuring rod that is slidably disposed on the inner wall of the rotating frame and a threaded cylinder that is threadedly installed on the side wall of the height measuring rod. The side wall of the height measuring rod is provided with equally spaced scale lines along the axial direction.

[0011] Furthermore, the height measuring mechanism also includes a mounting plate threaded onto the upper side wall of the height measuring rod, a connecting block fixed to the side wall of the mounting plate, and a fixing ring fixed to the end of the connecting block away from the mounting plate.

[0012] Furthermore, the locking mechanism includes a second fixing block placed on the upper end of two corresponding rotating frames on different sides, two screws fixed through the second fixing block, and a nut threaded onto the side wall of the screw. The screw is slidably disposed on the inner wall of the rotating frame, and the upper end of the nut abuts against the lower end of the rotating frame.

[0013] Furthermore, the control mechanism includes a controller, a wireless transceiver, a buzzer, and a data processor fixed to the side wall of the first bracket.

[0014] Furthermore, a limiting ring is fixed to the side wall of the limiting column, and the lower end of the limiting ring is attached to the upper end of the bearing plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a height measuring mechanism and a rotating frame, the problem of not being able to measure the height inside the trench in real time and accurately is solved. In use, the sliding block slides in the first limit groove of the bearing plate, which can drive the U-shaped block and the rotating frame hinged on it to move. The position of the rotating frame can be adjusted according to the position of the trench. The height measuring rod of the height measuring mechanism is inserted into the rotating frame, so that the lower end of the height measuring rod abuts against the bottom surface of the inner wall of the trench. The threaded cylinder is manually rotated so that the lower end of the threaded cylinder contacts the upper surface of the rotating frame. The height of the trench can be accurately obtained through the scale on the height measuring rod or in conjunction with the measurement data of the camera and control mechanism, realizing the real-time and accurate measurement of the height inside the trench.

[0017] 2. When measuring the elevation of the trench, the height measuring rod can also be manually removed from the rotating frame, the mounting plate can be threaded onto the upper side wall of the height measuring rod, and then the mounting plate can be inverted so that it rests against the bottom surface of the inner wall of the trench. The height can also be measured using the scale lines on the side wall of the height measuring rod.

[0018] 3. When the trenching equipment is not in use, bring the two corresponding rotating frames on different sides closer to each other, insert the screw on the second fixing block into the rotating frame, tighten the nut so that the upper end of the nut abuts against the lower end of the rotating frame, thereby locking the two rotating frames and preventing them from colliding when the equipment moves.

[0019] 4. By setting up a control mechanism and a camera, the camera can capture the construction environment in real time and transmit the image to the controller of the control mechanism. The camera can also capture the scale lines on the height measuring pole. The data processor processes the height data acquired by the height measuring mechanism. If the height is inconsistent, the controller will cause the buzzer to sound an alarm. At the same time, the wireless transceiver can transmit the data to the remote terminal, which makes it convenient for operators to adjust the working status of the trenching mechanism in a timely manner, thus improving the efficiency and quality of the work.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-6 A trenching device for constructing a retaining wall includes a bearing plate 1, a support body 2 fixed to the lower end of the bearing plate 1, rollers 3 rotatably mounted on both sides of the support body 2, a first bracket 4 fixed to the upper end of the bearing plate 1, an octagonal body 5 fixed to the upper end of the first bracket 4, cameras 6 fixed to each side wall of the octagonal body 5, a trenching mechanism 7 fixed to the first bracket 4, a drive mechanism 8 mounted on the trenching mechanism 7, a first fixing block 9 fixed to the bearing plate 1, and a device for trenching on the bearing plate 1. The upper end has two second limiting grooves 11 and a first limiting groove 10 opened on the four side walls of the bearing plate 1. The inner wall of the first limiting groove 10 is slidably provided with at least two sliding blocks 13. The end of the sliding block 13 away from the bearing plate 1 is fixedly connected to a U-shaped block 14. The upper end of the sliding block 13 is fixedly connected to a limiting post 15. The side wall of the limiting post 15 is slidably provided on the inner wall of the second limiting groove 11. A rotating frame 17 is hinged on the U-shaped block 14. A height measuring mechanism is inserted on the rotating frame 17. A control mechanism is provided on the first bracket 4.

[0029] The upper end of the support plate 1 is provided with at least four insertion holes 12 for placing the height measuring mechanism;

[0030] A locking mechanism is inserted on the rotating frame 17. When two rotating frames 17 on different sides and corresponding to each other approach each other, the locking mechanism is used to lock the two rotating frames 17.

[0031] In use, the height measuring mechanism is first placed in the insertion hole 12. The device is then pulled to the area near the retaining wall where a trench needs to be dug using machinery such as a car. Then, the drive mechanism 8 is activated by the control mechanism to drive the trenching mechanism 7. The trenching mechanism 7 can break the soil surface to form a trench. A person stands inside the trench and rotates the rotating frame 17 to insert the height measuring mechanism into the rotating frame 17. Finally, the lower end of the height measuring mechanism contacts the bottom of the inner wall of the trench. The camera 6 records and observes the height measuring mechanism, which can quickly compare whether the height measuring mechanisms at different positions are consistent. This allows it to be determined whether the elevations of the two points to be measured are consistent after the trench is excavated. This makes it convenient to use the trenching mechanism 7 or manually use a shovel to assist in excavating areas that have not been excavated to the required depth.

[0032] Please see Figure 2 In this embodiment, specifically: the trenching mechanism 7 includes an inclined block 71 fixed to one side of the first support 4, a rotating arm 72 rotatably connected to the inclined block 71, a turntable 73 rotatably connected to the upper end of the rotating arm 72, multiple cutting heads 74 fixed to the side wall of the turntable 73, a second support 76 fixed to the upper end of the rotating arm 72, and a cylinder 75 hinged to the lower end of the rotating arm 72. The output end of the cylinder 75 is hinged to the lower end of the inclined block 71. Through the cooperation of the inclined block 71, the rotating arm 72, and the cylinder 75, the extension and retraction of the cylinder 75 can drive the rotating arm 72 to rotate around the inclined block 71, thereby flexibly adjusting the working angle and depth of the turntable 73 and the cutting heads 74 to meet the trenching needs of different trenches. Multiple cutting heads 74 can improve trenching efficiency, and the second support 76 provides stable support for the subsequent installation of the drive mechanism 8.

[0033] Please see Figure 2 In this embodiment, specifically: the drive mechanism 8 includes a third bracket 81 fixed to the upper end of the second bracket 76, a motor 82 fixed to the upper end of the third bracket 81, and a first pulley 83 and a transmission belt 85 rotatably mounted on the upper end of the second bracket 76. The output shaft of the motor 82 passes through the third bracket 81 and is fixed to the rotating shaft of the first pulley 83. The side wall of the first pulley 83 is provided with the transmission belt 85. The first pulley 83 and the second pulley 84 are rotatably connected through the transmission belt 85. The lower end of the rotating shaft of the second pulley 84 passes through the second bracket 76 and is fixed to the rotating shaft of the turntable 73. The third bracket 81 provides a stable mounting base for the motor 82. The motor 82 can efficiently drive the turntable 73 to rotate through the transmission of the first pulley 83, the transmission belt 85 and the second pulley 84, which can reduce the impact of the motor 82 on the turntable 73 and the cutting head 74 during operation, ensure the stability of the trenching operation, and facilitate the control of the rotation speed of the turntable 73, thereby improving the trenching accuracy.

[0034] Please see Figure 6In this embodiment, the locking mechanism specifically includes a second fixing block 23 placed on the upper ends of two corresponding rotating frames 17 on different sides, two screws 24 fixedly connected to the second fixing block 23, and a nut 25 threaded onto the side wall of the screw 24. The screw 24 is slidably disposed on the inner wall of the rotating frame 17, and the upper end of the nut 25 abuts against the lower end of the rotating frame 17. The cooperation of the second fixing block 23, the screws 24 and the nut 25 can quickly lock the two corresponding rotating frames 17 on different sides. The operation is simple and convenient, which can effectively prevent the rotating frames 17 from colliding when the equipment moves, protect the components from damage, and extend the service life of the equipment.

[0035] Please see Figure 3 In this embodiment, the control mechanism specifically includes a controller 41, a wireless transceiver 42, a buzzer 43, and a data processor 44 fixed to the side wall of the first support 4. The controller 41 can coordinate the work of each component, and the data processor 44 can accurately process the height data obtained by the height measuring mechanism. If the height is inconsistent, the controller 41 can activate the buzzer 43 to issue an alarm in time to remind the operator. The wireless transceiver 42 can transmit data to a remote terminal to realize remote monitoring and management, which makes it convenient for the operator to adjust the working status of the trenching mechanism 7 in time, and greatly improves the work efficiency and quality.

[0036] Please see Figure 4 In this embodiment, specifically: a limiting ring 16 is fixedly connected to the side wall of the limiting post 15, and the lower end of the limiting ring 16 is attached to the upper end of the bearing plate 1. The limiting ring 16 can axially limit the limiting post 15, prevent the limiting post 15 from excessive displacement during operation, ensure the stability of the connection between the limiting post 15 and the bearing plate 1, and thus ensure the positional stability of the entire height measuring mechanism and the rotating frame 17 and other components, providing a reliable guarantee for accurate measurement.

[0037] Example 1: In this example, the height measuring mechanism includes a height measuring rod 18 slidably mounted on the inner wall of the rotating frame 17 and a threaded cylinder 19 threadedly mounted on the side wall of the height measuring rod 18. The side wall of the height measuring rod 18 has equidistant scale lines along the axial direction. The height measuring rod 18 can slide flexibly within the rotating frame 17, making it easy to adjust its position according to the trench depth. The threaded cylinder 19 can fix the position of the height measuring rod 18 by contacting the upper end face of the rotating frame 17. With the help of the scale lines on the height measuring rod 18, the trench height data can be read directly. The structure is simple and practical.

[0038] Example 2: Based on Example 1, this example provides a technical solution: The height measuring mechanism further includes a mounting plate 20 threadedly mounted on the upper side wall of the height measuring rod 18, a connecting block 21 fixed to the side wall of the mounting plate 20, and a fixing ring 22 fixed to the end of the connecting block 21 away from the mounting plate 20. The mounting plate 20 is threadedly connected to the height measuring rod 18, which facilitates disassembly and installation. When inverted measurement is required, the mounting plate 20 is pressed against the bottom surface of the inner wall of the trench, and the height can be measured through the scale line of the height measuring rod 18, which increases the flexibility of the height measurement method. The connecting block 21 and the fixing ring 22 provide auxiliary fixing and gripping points for the mounting plate 20, which is convenient for operators to use and operate, further improving the practicality of the height measuring mechanism.

[0039] Working principle: When in use, first place the height measuring mechanism in the insertion hole 12 on the bearing plate 1, and use a car or other machinery to pull the device to the location where the trench needs to be dug near the retaining wall. The drive mechanism 8 is activated by the control mechanism on the first bracket 4. The output shaft of the motor 82 in the drive mechanism 8 drives the first pulley 83 on the third bracket 81 to rotate. The first pulley 83 drives the second pulley 84 to rotate through the transmission belt 85, which in turn drives the turntable 73 and the cutting head 74 in the trenching mechanism 7 to rotate. At the same time, the cylinder 75 of the trenching mechanism 7 can extend and retract to drive the rotating arm 72 to rotate around the inclined block 71, flexibly adjusting the working angle and depth of the turntable 73 and the cutting head 74 to break the soil surface and form a trench.

[0040] After the trench is formed, personnel stand inside the trench and push the sliding block 13 in the first limiting groove 10 of the bearing plate 1. This causes the sliding block 13 to drive the U-shaped block 14 and the limiting post 15 to slide to the appropriate position in the second limiting groove 11. The rotating frame 17 on the U-shaped block 14 is rotated, and two sets of height measuring mechanisms (height measuring rod 18 and threaded cylinder 19 in embodiment 1; mounting plate 20, connecting block 21, and fixing ring 22 are added in embodiment 2) are respectively inserted into the rotating frame 17 located on the side of the trench. The height measuring mechanisms are adjusted so that the lower end contacts the bottom surface of the inner wall of the trench. The position of the height measuring rod 18 is fixed by the threaded cylinder 19, and the other two sets of height measuring mechanisms are inserted at the same time. On the rotating frame 17 located on the ground side, with its lower end in contact with the ground, the camera 6 on the side wall of the octagonal body 5 synchronously records and observes all height measuring mechanisms. The data processor 44 processes the height data, which can not only compare whether the elevations of the two points to be measured in the trench are consistent, but also compare the height data of the height measuring mechanisms placed in the trench with those placed on the ground to obtain the elevation difference between the ground and the trench. If there is an inconsistency or does not meet the requirements, the controller 41 activates the buzzer 43 to sound an alarm, and the wireless transceiver 42 transmits the data to the remote terminal so that the trenching mechanism 7 or manual hand tools can be used to process the unexcavated areas.

[0041] When the equipment needs to be moved, the operator first removes each set of height measuring mechanisms from the rotating frame 17 and puts them back into the insertion holes 12 on the support plate 1. Then, the operator pushes the sliding blocks 13 located in the first limiting grooves 10 on different side walls of the support plate 1 and corresponding in position. This causes the sliding blocks 13 to drive the U-shaped blocks 14 and the limiting posts 15 to slide along the second limiting grooves 11 toward the center of the support plate 1. During the process, the limiting rings 16 on the limiting posts 15 are always in contact with the upper end face of the support plate 1. Through the frictional resistance between the limiting rings 16 and the support plate 1 and the axial limiting effect on the limiting posts 15, the sliding blocks 13 are prevented from shifting up and down or sliding excessively during the sliding process, ensuring that the sliding blocks 13 and the connected U-shaped blocks 14 and rotating frame 17 move smoothly.

[0042] After the two corresponding rotating frames 17 on different sides approach each other, the second fixing block 23 of the locking mechanism is placed on the upper surface of the two rotating frames 17, so that the two screws 24 fixed through the second fixing block 23 are respectively inserted into the inner wall of the two rotating frames 17 until the lower end of the screw 24 passes through the rotating frame 17. Then, the nut 25 is threaded onto the side wall of the screw 24 that passes through the rotating frame 17, and the nut 25 is tightened so that its upper end is tightly against the lower surface of the rotating frame 17. Through the cooperation of the second fixing block 23, the screw 24 and the nut 25, the two corresponding rotating frames 17 are firmly locked into one, which can prevent the rotating frames 17 from shaking or colliding due to bumps when the equipment moves. At the same time, the limiting ring 16 continuously plays a stabilizing and limiting role on the sliding block 13 and the limiting post 15, ensuring that the entire sliding block 13, U-shaped block 14 and rotating frame 17 assembly is fixed on the bearing plate 1, providing a reliable guarantee for the structural stability during the movement of the equipment.
