Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering equipment, in particular to a traction device used for traveling on a municipal slope protection lattice beam. Background Art

[0002] Slope greening is a common ecological slope protection method used in municipal engineering projects, effectively protecting exposed slopes. Combined with traditional lattice beam slope protection, it can effectively restore ecological vegetation on slopes. Lattice beams consist of horizontal and vertical beams in a grid-like pattern. On steep rocky or rocky surfaces, greening sprayers are often used to spray a mixture of greening plant seeds and soil into the spaces between the lattice beams. This allows for greening of the gaps between the beams. Combining slope greening with traditional lattice beam slope protection not only conserves water and soil, but also improves the environment and landscape.

[0003] When the current greening sprayer is performing greening operations, the greening sprayer is located at the bottom of the slope and relies on a high-pressure pump to spray the mixed greening plant seeds and foreign soil onto the slope through the gun head. It is simple to operate and has a fast construction speed.

[0004] However, for steep and high slopes, the high-pressure pump on the greening sprayer cannot spray the mixed greening plant seeds and foreign soil to a sufficient operating height, making it difficult to complete the greening spraying operation on the high slope. Summary of the Invention

[0010] A plurality of guide mechanisms are installed at intervals along the length of the fixing frame; the guide mechanism includes: a first electric cylinder and a mounting frame, the cylinder body of the first electric cylinder is fixedly connected to the fixing frame, and the telescopic rod of the first electric cylinder is fixedly connected to the first mounting frame; two second electric cylinders are symmetrically installed on the first mounting frame, the ends of the telescopic rods of the second electric cylinders are fixedly connected to clamping arms, and positioning wheels are rotatably installed on the free ends of the clamping arms;

[0011] a distance sensor, mounted on the lower side of the first mounting frame;

[0012] The controller is connected to the first electric cylinder, the second electric cylinder and the distance sensor through a control circuit; when the distance sensor detects that the distance from the crossbeam of the lattice beam is greater than a preset value, the controller sends an extension instruction to the first electric cylinder; when the first electric cylinder is extended to a preset position, the controller sends a retraction instruction to the second electric cylinder, so that the two positioning wheels clamp the longitudinal beam of the lattice beam; when the distance sensor detects that the distance from the crossbeam of the lattice beam is less than a preset value, the controller sends an extension instruction to the second electric cylinder; when the second electric cylinder is extended to a preset value, the controller sends a retraction instruction to the first electric cylinder, so that the height of the positioning wheels is higher than the height of the crossbeam of the lattice beam, so that the positioning wheels cross the crossbeam.

In the initial state, since the lattice beam has longitudinal beams, the drive mechanism is placed on the longitudinal beams. When the distance sensor detects that the distance from the lattice beam to the crossbeam is greater than a preset value, the controller issues an extension command to the first electric cylinder. When the first electric cylinder extends to a preset position, the controller issues a retraction command to the second electric cylinder, causing the two positioning wheels to clamp the longitudinal beams of the lattice beam. Because the lattice beam also has crossbeams, the crossbeams obstruct the passage of the guide mechanism. In this solution, when the distance sensor detects that the distance from the lattice beam to the crossbeam is less than a preset value, the controller issues an extension command to the second electric cylinder. When the second electric cylinder extends to a preset value, the controller issues a retraction command to the first electric cylinder, causing the positioning wheels to be higher than the height of the crossbeams of the lattice beam, allowing the positioning wheels to cross the crossbeams. This drives the gun head of the greening spraying equipment to move on the longitudinal beam of the lattice beam, so that the gun head can be moved to a higher position on the lattice beam, thereby facilitating spraying operations on steep and high slopes.

DETAILED DESCRIPTION

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

[0028] A traction device for traveling on municipal slope protection lattice beams, see Figure 1-5 The system comprises a fixed frame 1, a clamping mechanism 2, a driving mechanism 3, a guide mechanism 4, a distance sensor 5, and a controller. The clamping mechanism 2 is mounted on the upper side of the fixed frame 1 and is used to clamp the nozzle of the greening spraying equipment. The driving mechanism 3 is mounted on the lower side of the fixed frame 1 and is used to drive the fixed frame 1 on the lattice beam. Four sets of guide mechanisms 4 are installed at intervals along the length of the fixed frame 1. Each set of guide mechanisms 4 has a drive mechanism 3 installed between two guide mechanisms 4. The guide mechanism 4 comprises a first electric cylinder 401 and a first mounting frame 405. The cylinder body of the first electric cylinder 401 is fixedly connected to the fixed frame 1, and the telescopic rod of the first electric cylinder 401 is fixedly connected to the first mounting frame 405. Two second electric cylinders 402 are symmetrically mounted on the first mounting frame 405, and the ends of the telescopic rods of the second electric cylinders 402 are fixedly connected to clamping arms 403. Positioning wheels 404 are rotatably mounted on the free ends of the clamping arms 403, which can roll along the longitudinal direction of the lattice girder. The ends of the clamping arms 403 connected to the positioning wheels 404 are bent horizontally inward, forming an L-shape. The lower ends of the two clamping arms 403 corresponding to the same guide mechanism 4 are close to each other. A distance sensor 5 is mounted on the underside of the first mounting frame 405, specifically near the end of the first mounting frame 405. In this embodiment, preferably, the distance between two adjacent guide mechanisms 4 is greater than the width of the crossbeam of the lattice beam, so that when the guide mechanism 4 crosses the crossbeam of the lattice beam, there are still three groups of guide mechanisms 4 connected to the longitudinal beam of the lattice beam, thereby ensuring the guiding and clamping effect of the guide mechanism 4 on the longitudinal beam.

[0029] The controller uses a single-chip microcomputer in the prior art, and is connected to the first electric cylinder 401, the second electric cylinder 402 and the distance sensor 5 through a control circuit. When the distance sensor 5 detects that the distance from the crossbeam of the lattice girder is greater than a preset value, the controller sends an extension instruction to the first electric cylinder 401. When the first electric cylinder 401 is extended to a preset position, the controller sends a retraction instruction to the corresponding second electric cylinder 402, so that the two positioning wheels 404 clamp the longitudinal beam of the lattice girder. When the distance sensor 5 detects that the distance from the crossbeam of the lattice girder is less than a preset value, the controller sends an extension instruction to the second electric cylinder 402. When the second electric cylinder 402 is extended to the preset value, the controller sends a retraction instruction to the corresponding first electric cylinder 401, so that the height of the positioning wheel 404 is higher than the height of the crossbeam of the lattice girder, so that the positioning wheel 404 can cross the crossbeam.

[0030] By adopting the technical solution of this embodiment, the nozzle head of the greening spraying equipment is fixed by the clamping mechanism 2, and the fixed frame 1 is driven by the driving mechanism 3 to move on the lattice girder. In the initial state, since the lattice girder has longitudinal beams, the driving mechanism 3 is placed on the longitudinal beams. When the distance sensor 5 detects that the distance from the lattice girder's crossbeam is greater than a preset value, the controller issues an extension command to the first electric cylinder 401. When the first electric cylinder 401 extends to a preset position, the controller issues a retraction command to the second electric cylinder 402, causing the two positioning wheels 404 to clamp the longitudinal beams of the lattice girder. Since the lattice girder also has crossbeams, the crossbeams block the passage of the guide mechanism 4. In this solution, when the distance sensor 5 detects that the distance from the lattice girder is less than a preset value, the controller issues an extension command to the second electric cylinder 402. When the second electric cylinder 402 extends to the preset value, the controller issues a retraction command to the first electric cylinder 401, causing the positioning wheel 404 to be higher than the height of the lattice girder's crossbeams, allowing it to straddle the crossbeams. This allows the guide mechanism 4 to automatically straddle the crossbeams, facilitating the movement of the spray gun head of the greening spraying equipment along the longitudinal beams of the lattice girder, allowing the gun head to reach a higher position on the lattice girder, thus facilitating spraying operations on steep and high slopes. This effectively addresses the problem of insufficient spraying height in existing greening sprayers and reduces operational safety risks.

[0031] Please continue reading Figure 1-2On the basis of the technical solution of the above embodiment, preferably, the clamping mechanism 2 includes a fixed column 201, a connecting rod 202, a first clamp 203 and a second clamp 204; the fixed column 201 is fixedly connected to the fixing frame 1, and the connecting rod 202 is connected to the fixed column 201; the first clamp 203 is fixedly connected to the connecting rod 202, and the first clamp 203 and the second clamp 204 are both arc-shaped clamps, and the corresponding ends of the first clamp 203 and the second clamp 204 are hinged, and the other ends of the first clamp 203 and the second clamp 204 are connected by a locking bolt 205.

[0032] By adopting the technical solution of this embodiment, the gun head of the greening sprayer is clamped by the first clamp 203 and the second clamp 204, so that the gun head is fixed on the fixing frame 1, making it convenient for the fixing frame 1 to move on the lattice beam with the gun head.

[0033] Please continue reading Figure 2 To adjust the spraying angle of the gun tip to suit different operating requirements, the technical solution of the above embodiment further includes a third electric cylinder 206. The third electric cylinder 206 is fixedly mounted on the fixing frame 1. The telescopic rod of the third electric cylinder 206 is hinged to one end of the connecting rod 202; the top end of the fixing column 201 is hinged to the other end of the connecting rod 202. In the initial state, the angle between the connecting rod 202 and the fixing frame 1 is adjusted by adjusting the extension length of the telescopic rod of the third electric cylinder 206, thereby adjusting the operating angle of the gun tip.

[0034] To adjust the spraying angle of the gun tip to suit different work requirements during the spraying operation, a wireless communication module (not shown) is further installed on the fixed frame 1. The wireless communication module and the third electric cylinder 206 are both connected to the controller via control circuitry. During the spraying operation, a signal is sent to the wireless communication module to adjust the extension length of the telescopic rod of the third electric cylinder 206. The wireless communication module transmits this signal to the controller, which then issues a corresponding command to adjust the extension length of the telescopic rod to the third electric cylinder 206. This allows the third electric cylinder 206 to adjust the extension length of the telescopic rod during the spraying operation, thereby adjusting the working angle of the gun tip.

[0035] Please continue reading Figure 1 and Figure 5Based on the above embodiment, preferably, the drive mechanism 3 includes a drive sleeve 301, a drive sleeve 301, a drive rod 302, and a second mounting frame 303. The drive sleeve 301 is fixedly connected to the lower side of the fixing frame 1 and is arranged vertically. The drive rod 302 is slidably connected within the drive sleeve 301, and one end of the drive rod 302 extends outside the drive sleeve 301 and is fixedly connected to the second mounting frame 303. A drive shaft 304 is rotatably mounted on the bottom of the second mounting frame 303, and drive wheels 305 are fixedly connected to both ends of the drive shaft 304. A drive motor 306 is fixedly mounted on the upper side of the second mounting frame 303. A through hole 307 is formed in the second mounting frame 303. The drive motor 306 drives the drive shaft 304 to rotate via a transmission assembly 308. To increase the torque output by the drive motor 306 on the drive shaft 304, the transmission assembly 308 uses a reduction gear assembly, which passes through the through hole 307 and is connected to the drive shaft 304. The drive motor 306 is connected to a controller via a control circuit. When in use, the drive motor 306 drives the drive shaft 304 to rotate through the reduction gear assembly, and the drive shaft 304 drives the drive wheel 305 to rotate. The drive wheel 305 contacts the longitudinal beam of the lattice beam, and the friction between the drive wheel 305 and the longitudinal beam enables the entire device to move longitudinally along the longitudinal beam.

[0036] Please continue reading Figure 5 Based on the above embodiment, to enable the drive wheel 305 to adapt to the uneven surface of the longitudinal beams of the lattice girder, a first wing ring 309 is further provided on the outer side of the end of the drive sleeve 301 away from the fixing frame 1, and a second wing ring 310 is provided on the end of the drive rod 302 connected to the second mounting frame 303. A compression spring 311 is sleeved on the drive rod 302, one end of the compression spring 311 abutting against the first wing ring 309 and the other end against the second wing ring 310. When the drive wheel 305 travels on the longitudinal beams of the lattice girder, the upper surface of the longitudinal beams may become uneven due to construction reasons, causing the drive wheel 305 to abut against the protruding portion of the longitudinal beams, hindering the drive wheel 305's movement. In this embodiment, the provision of the compression spring 311 allows the drive wheel 305 to move axially along the drive rod 302 to a certain extent, thereby adapting to the uneven surface of the longitudinal beams and preventing obstruction by the protruding portions of the longitudinal beams that could affect the movement of the drive mechanism 3.

[0037] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
