Detailed Implementation

[0015] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] This utility model provides an underground roadway construction vehicle, including a frame 1 and a tracked walking assembly 2. The frame 1 is provided with an operating console 3 in the middle. Both ends of the frame 1 are equipped with a first hollow rotating platform 4. The first hollow rotating platform 4 is provided with a column 5. A second hollow rotating platform 6 is provided on one side of the column 5. The second hollow rotating platform 6 is equipped with a clamping mechanism 8 through a telescopic arm 7. The two telescopic arms 7 and the clamping mechanism 8 are used in coordination to better cope with different working conditions.

[0017] like Figure 1 As shown, during use, the chassis 1 is driven by the tracked walking assembly 2, which is driven by a motor. The tracked structure can adapt to complex terrain in the roadway. Materials can be loaded on the chassis 1 to realize material recovery in the mining roadway and short-distance material transportation, saving manual handling and reducing labor intensity. The clamping mechanism 8 can be used to clamp the roadway pipeline. The first hollow rotating platform 4 realizes the horizontal rotation of the telescopic arm 7 and the clamping mechanism 8, and the second hollow rotating platform 6 controls the vertical rotation of the telescopic arm 7 and the clamping mechanism 8. With the extension and retraction of the telescopic arm 7, the posture of the clamped pipeline is changed to meet the multi-angle installation, disassembly or transfer of pipeline.

[0018] The column 5 is a hollow structure. Inside the column 5, from bottom to top, a first hydraulic cylinder and an upper clamping member 9 are arranged sequentially. A second hydraulic cylinder 10 is provided on the first hollow rotating platform 4. The output end of the second hydraulic cylinder 10 is connected to the column 5. A third hydraulic cylinder 11 is installed on the frame 1 on both sides of the first hollow rotating platform 4. The output end of the third hydraulic cylinder 11 is connected to a lower clamping member 12. Both the upper clamping member 9 and the lower clamping member 12 are provided with several protrusions 13.

[0019] like Figure 2 and 3 As shown, in this embodiment, if it is necessary to fix the position of the equipment, the third hydraulic cylinders 11 on both sides of the frame 1 are activated to push the lower clamping member 12 to extend and clamp the bottom of the tunnel. At the same time, the first hydraulic cylinder inside the column is activated to push the upper clamping member 9 to extend and clamp the top of the tunnel. The protrusions 13 on the upper clamping member 9 and the lower clamping member 12 enhance the friction with the contact surface and prevent the equipment from shaking during operation. The extension and retraction of the second hydraulic cylinder 10 drives the column 5 to rise and fall, thereby realizing the lifting and lowering of the clamped pipe to meet the operation requirements. It is also suitable for construction operations in low tunnels.

[0020] The telescopic arm 7 includes a slide rail 71 fixedly mounted on the second hollow rotating platform 6. A first sliding sleeve 72 is slidably mounted on the slide rail 71. A second sliding sleeve 73 is slidably mounted inside the first sliding sleeve 72. A fourth hydraulic cylinder 74 is installed inside the second sliding sleeve 73. One end of the fourth hydraulic cylinder 74 is connected to the first sliding sleeve 72, and the other end of the fourth hydraulic cylinder 74 is connected to one end of the second sliding sleeve 73. A clamping mechanism 8 is mounted on one end of the second sliding sleeve 73. A fifth hydraulic cylinder 75 is installed below the slide rail 71. The output end of the fifth hydraulic cylinder 75 is hinged to the first sliding sleeve 72.

[0021] like Figure 2 As shown, the first sliding sleeve 72 is pushed to slide along the slide rail 71 by the fifth hydraulic cylinder 75. At the same time, the second sliding sleeve 73 inside the first sliding sleeve 72 is further extended and retracted under the action of the fourth hydraulic cylinder 74, realizing the multi-stage extension of the telescopic arm 7 and expanding the working range.

[0022] The clamping mechanism 8 includes an upper clamping member 81, a lower clamping member 82, and a sixth hydraulic cylinder 83. The upper clamping member 81 and the lower clamping member 82 are both installed at one end of the second sliding sleeve 73. The lower clamping member 82 is installed at one end of the second sliding sleeve 73 by a pin. The upper clamping member 81 is hinged to one end of the second sliding sleeve 73 and is located on top of the lower clamping member 82. The sixth hydraulic cylinder 83 is installed on top of the upper clamping member 81. The clamping or releasing of the clamping mechanism 8 is controlled by the extension and retraction of the sixth hydraulic cylinder 83.

[0023] like Figure 3 As shown, in this embodiment, by controlling the extension and retraction of the sixth hydraulic cylinder 83 at the top of the upper clamping member 81, the opening and closing of the upper clamping member 81 and the lower clamping member 82 are controlled, thereby completing the clamping of the material.

[0024] The control panel 3 is equipped with a pneumatic motor and a hydraulic pump. The output end of the pneumatic motor is connected to the input end of the hydraulic pump. The output end of the hydraulic pump is connected to a control element, which is a manual directional valve. The output end of the control element is connected to multiple oil circuits.

[0025] like Figure 1 As shown, since compressed gas is readily available at the bottom of the coal mine, the power source in this embodiment is compressed gas, which is converted into hydraulic power to drive various actions of the equipment, reducing resource consumption and cost. The operator controls the equipment through the control panel in the middle of the chassis 1. The pneumatic motor in the control panel 3 drives the hydraulic pump, and the hydraulic pump distributes power to each oil circuit through the manual reversing valve, converting hydraulic energy into mechanical energy to provide power for various actions of the track motor and clamping mechanism.

[0026] Operating principle: The track motor is controlled by a control element to move the equipment to a designated position. The upper clamping member 9 and lower clamping member 12 are activated, and through the extension and retraction of corresponding hydraulic cylinders, they clamp the top and bottom of the tunnel respectively. The protrusion 13 increases the friction of the contact surface, forming stable support. According to actual needs, the position of the clamping mechanism 8 can be adjusted in multiple dimensions. Specifically, the first hollow rotating platform 4 can drive the column 5, telescopic arm 7, and clamping mechanism 8 to rotate 360° horizontally, changing the orientation of the clamping mechanism 8 on the pipe and expanding the horizontal working range. The second hydraulic cylinder 10 raises and lowers, driving the second hollow rotating platform 6, telescopic arm 7, and clamping structure 8 to adjust the height. The second hollow rotating platform 6 can drive the telescopic arm 7 and clamping mechanism 8 to rotate vertically, achieving the up-and-down tilting of the telescopic arm 7 and clamping mechanism 8. The telescopic arm 7, driven by the fifth hydraulic cylinder, slides along the slide rail with the first sliding sleeve, and in conjunction with the extension and retraction of the second sliding sleeve 73, adjusts the length of the clamping mechanism 8 to meet different distance operating requirements.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
