Detailed Implementation

[0019] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0020] like Figures 1-5 As shown, the pneumatic tracked hydraulic lifting vehicle includes a frame body 1, a tracked travel assembly 2, an oil tank assembly, a pump station assembly, a hydraulic lifting platform, an operating platform, and a support assembly.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, there are two tracked walking assemblies 2, which are symmetrically connected to the bottom left and right sides of the chassis 1 to provide overall support and drive the overall movement. The tracked walking assembly 2 includes a guide wheel, a track roller, a sprocket, and a tensioning device. It uses a combined sealed track chain made of high-strength alloy steel to ensure the normal operation of the lifting vehicle in harsh environments. The track roller not only directly bears the weight of the machine but also withstands the impact from the top plate. The tensioning device is used to control the slack of the track within the range of 10-200mm.

[0022] like Figure 1 and Figure 3As shown, the oil tank assembly includes an oil tank body 22, which is installed at the top end of the vehicle frame 1. The oil tank body 22 is designed with a large capacity to meet the needs of the entire hydraulic system of this utility model and to prevent the normal operation of the entire hydraulic system from being affected by excessively high liquid levels in the oil tank body 22. A filter, an air filter, and a level gauge 23 are installed on the oil tank body 22. The filter includes a suction filter and a return filter. The suction filter prevents large particles of impurities from being sucked into the pump, thereby controlling the contamination of the hydraulic system, improving the cleanliness of the system, and protecting the hydraulic components of the system from damage. The return filter is used to filter metal particles and other contaminants generated by component wear in the hydraulic system, ensuring that the oil flowing back to the oil tank body 22 remains clean. The air filter is used for air filtration during operation and oil filtration during refueling. The level gauge 23 allows for a direct view of the liquid level in the oil tank body 22.

[0023] like Figure 1 and Figure 3 As shown, the pump station assembly includes a pump station housing 24, a pneumatic motor, a gear pump, and a gearbox. The pump station housing 24 is installed on the top of the vehicle frame 1 at the end opposite to the oil tank housing 22. The pneumatic motor, gear pump, and gearbox are all installed inside the pump station housing 24. The pneumatic motor and gear pump are connected as one unit through the gearbox. The inlet of the gear pump is connected to the outlet of the suction filter through a pipeline. An oil mist lubricator 25 is installed on the side wall of the pump station housing 24 facing the oil tank housing 22. Compressed air enters the pneumatic motor after passing through the oil mist lubricator 25, driving the pneumatic motor to operate. The pneumatic motor drives the gearbox, and the gearbox drives the gear pump to draw hydraulic oil from the oil tank housing 22 and output high-pressure oil. A booster 3 is installed on the frame body 1 between the oil tank body 22 and the pump station body 24. The booster 3 is connected to the gear pump through a pipeline. When the pressure of the high-pressure oil output by the gear pump cannot meet the rated working pressure required for the tensioning equipment, anchor cable cutter, etc., the booster 3 is used to boost the pressure and provide hydraulic power to the tensioning equipment, anchor cable cutter, etc., thus expanding the scope of application of this utility model. The booster 3 in this utility model can boost the pressure to 65 MPa.

[0024] like Figure 1 , Figures 3-5As shown, the hydraulic lifting platform includes a fixed base 12, a lifting cylinder 13, a lifting folding frame 14, and an operating platform 15. The fixed base 12 connects the oil tank assembly and the pump station assembly. Specifically, in actual use, the oil tank body 22 and the pump station body 24 are processed to have the same height and maintain sufficient strength. The two ends of the fixed base 12 are respectively connected to the top of the oil tank body 22 and the top of the pump station body 24. The lifting folding frame 14 is installed on the fixed base 12 and adopts a scissor-type structure. The operating platform 15 is installed on the top of the lifting folding frame 14. The fixed end of the lifting cylinder 13... Hinged to the fixed base 12, the extended end of the lifting cylinder 13 is hinged to the lifting folding frame 14. Through the extension and retraction of the lifting cylinder 13, the lifting folding frame 14 and the operating platform 15 of the scissor-type structure are driven to lift and lower. Operators can perform specific construction work on the operating platform 15. Guardrails 16 are installed around the top of the operating platform 15 to improve the safety of operators. The guardrails 16 are installed in a foldable manner with the operating platform 15. When the guardrails 16 are upright, they provide protection. When the guardrails 16 are folded into the plane of the operating platform 15, the height is reduced, making it easier to pass through narrow spaces.

[0025] like Figures 1-4As shown, there are two support assemblies, which are respectively installed at the front and rear ends of the frame 1. Each support assembly includes a fixed support seat 4, which is bolted to the frame 1. The fixed support seat 4 has a hollow structure, and two telescopic support seats 5 are installed within its hollow cavity. The two telescopic support seats 5 are located at both ends of the fixed support seat 4 and are slidably fitted with it. Support cylinders 6 are installed at the far ends of the two telescopic support seats 5. A support plate 7 is hinged to the extended end of each support cylinder 6. The extension of the support cylinder 6 drives the support plate 7 to support the ground. The support plate 7 has a disc-shaped structure, increasing the support area and improving stability during operation. To further enhance the reliability of the support between the support plate 7 and the ground, several evenly distributed insertion protrusions 11 are machined on the bottom surface of the support plate 7. The end of the support plate 7 is processed into a pointed conical structure, which can be inserted below the ground. The hinged method of the support plate 7 allows the support plate 7 to automatically adjust to adapt to changes in terrain. Multiple evenly distributed locking holes 8 are processed on the fixed support base 4, and the locking holes 8 penetrate the fixed support base 4. The telescopic support base 5 is processed with positioning holes 9. By sliding the telescopic support base 5, the positioning hole 9 can be aligned with one of the locking holes 8. Locking pins 10 can be inserted into the corresponding locking holes 8 and positioning holes 9 to lock the position of the telescopic support base 5 relative to the fixed support base 4. By cooperating with different locking holes 8, the telescopic support base 5 can extend to different distances relative to the fixed support base 4, so as to achieve flexible adjustment of the support. When the two telescopic support bases 5 are completely retracted into the fixed support base 4, the distance between the two support cylinders does not exceed the width of the frame body 1, and will not affect the overall movement.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the control panel is installed at one end of the chassis 1. The control panel includes a valve seat 17, which is a welded steel plate structure. A multi-way directional valve 18 is installed inside the valve seat 17. The multi-way directional valve 18 is connected to the gear pump pipeline. The track walking assembly 2, the support cylinder 6, the lifting cylinder 13, and the booster 3 are all connected to the multi-way directional valve 18 pipeline and controlled by the multi-way directional valve 18. A handle is installed on the multi-way directional valve 18 for easy operation. A gauge mounting base 19 is installed on the top of the valve seat 17. Two pressure gauges are installed on the gauge mounting base 19. One pressure gauge is a hydraulic gauge 20, which is used to display the system hydraulic working pressure. The other pressure gauge is a pneumatic gauge 21, which is used to display the system air source pressure.

[0027] The working principle of this utility model is as follows: Compressed air enters the pneumatic motor after passing through the oil mist lubricator 25. The pneumatic motor drives the gear pump through the reduction gearbox to draw hydraulic oil from the oil tank 22 and pressurize it. The manual operation of the multi-way directional valve 18 handle controls the track walking assembly 2 to realize the overall forward, backward, left and right movement and turning of this utility model. When it moves to the designated working position, the manual pulls out the locking pin 10 and pulls the telescopic support seat 5 to move outward along the fixed support seat 4. After it extends into place, the locking pin 10 is reinserted into the corresponding locking hole 8 and positioning hole 9 to complete the positioning of the telescopic support seat 5. The multi-way directional valve 18 handle controls the support cylinder 6 to extend, so that the support plate 7 is supported on the ground. The insertion protrusion 11 is inserted below the ground to improve the stability during operation. After the support is stable, the multi-way directional valve 18 controls the lifting cylinder 13 to extend, which drives the lifting folding frame 14 to unfold and the operating platform 15 to rise. The operator can perform corresponding work on the operating platform 15. When working at height, the guardrail 16 ensures personal safety. The gear pump of this utility model can also provide hydraulic power for hydraulic anchor drilling rigs, or completely retract the support cylinder 6 into the fixed support seat 4 and fold the guardrail 16 to reduce the overall space size, making it convenient and quick to move in narrow spaces. Through the cooperation of the gear pump and the booster 3, it provides high-pressure oil for anchor cables, anchor cutters, and tensioning tools, realizing integrated construction of anchor cables and anchors on the top of the roadway, and cutting of exposed ultra-long anchor cables and anchors. It achieves multi-purpose use, wide applicability, and strong versatility.
