[0007] By adopting the above technical scheme, the pipeline is wound on the roller surface of the winding roller, and the slider is driven to slide along the inner wall of the adjusting channel, which drives the two connecting rods to rotate, and drives the two sliding seats to slide on the inner wall of the sliding channel, so that the distance between the two sliding seats matches the length in the axial direction of the winding roller, and the rotating shaft of the winding roller is embedded in the limiting component one by one. According to the winding thickness of the pipeline on the roller surface of the winding roller, the limiting component is driven to slide on the sliding frame, so that the pipeline wound on the winding roller is not easy to abut the surface of the base, and the wear between the pipeline and the base is reduced, thereby improving the stability of the underground pipeline laying, and making the length of the pipeline wound on the winding roller unlimited, which can meet the needs of different pipeline laying, thereby improving the practicability of the underground pipeline laying equipment.

[0008] Optionally, the limit device also includes at least two limit screws and at least two hand wheels, the hand wheels correspond one-to-one to the limit screws and are coaxially connected to the ends of the limit screws, the surface of the sliding seat is provided with a limit channel for the sliding of the limit component, the limit screw corresponds one-to-one to the sliding seat, the end of the limit screw away from the hand wheel passes through the surface of the sliding seat and is rotatably connected to the inner wall of the limit channel, the axis of the limit screw and the height direction of the base are parallel to each other, and the limit component is threadedly connected to the outer wall of the limit screw.

[0009] By adopting the above technical solution, the handwheel is held by the staff to drive the limit screw to rotate, driving the limit assembly to slide to the specified height on the inner wall of the limit channel, thereby achieving precise control of the sliding height of the limit assembly on the sliding seat, thereby improving the ease of use of underground pipeline laying equipment.

[0010] Optionally, the limit assembly includes a limit seat, a clamping seat and an elastic member, the limit seat being threadedly connected to the outer wall of the limit screw, the clamping seat being slidably connected to the surface of the limit seat, the sliding direction of the clamping seat and the width direction of the base being parallel to each other, a limit hole for the end of the rotating shaft of the winding roller to be embedded is reserved between the limit seat and the clamping seat, one end of the elastic member in the elastic force direction is connected to the surface of the limit seat, the other end of the elastic member in the elastic force direction is connected to the surface of the clamping seat, the elastic member has elastic force to drive the clamping seat to slide in the direction away from the limit seat, and there is a tendency for the clamping seat and the limit seat to be spliced ​​to form a limit hole.

[0011] By adopting the above technical scheme, when the winding roller is installed, the elastic force of the elastic member is overcome to drive the clamping seat to slide in the direction close to the limit seat, the limit hole on the limit seat is opened, and the end of the rotating shaft of the winding roller is embedded in the limit hole on the limit seat. When the clamping seat is released, the elastic force of the elastic member drives the clamping seat to slide in the direction away from the limit seat. The limit seat and the clamping seat are spliced ​​to form a limit hole, and the inner wall of the limit hole is pressed against the outer peripheral surface of the rotating shaft of the winding roller to form a limit, so that the end of the rotating shaft of the winding roller is not easy to separate from the limit seat and the clamping seat, thereby improving the limit stability of the winding roller on the limit seat.

[0012] Optionally, the limit seat is connected to an exhaust assembly, which includes a second connecting rod, an exhaust piston and a filter. The top surface of the limit seat is provided with an exhaust flow channel for the exhaust piston to slide. The sliding direction of the exhaust piston and the axis of the limit screw are parallel to each other. One end of the second connecting rod is rotatably connected to the surface of the clamping seat, and the other end of the second connecting rod is rotatably connected to the surface of the exhaust piston. The exhaust flow channel is connected to the limit hole, and the filter is connected to the inner wall of the exhaust flow channel near the limit hole.

[0013] The venting of the air filter by the venting piston causes the venting piston to move in a direction away from the limit seat, thereby preventing the venting piston from sliding along the inner wall of the venting passage and causing the venting piston to move in a direction away from the limit seat.

[0014] Optionally, the exhaust assembly also includes a one-way valve 1, a one-way valve 2 and a filter plate, the surface of the limit seat facing the winding roller is provided with an air supply channel, the air supply channel is connected to the exhaust channel, the filter plate is connected to the inner wall of the air supply channel, the filter plate surface is flush with the surface of the limit seat, and the filter plate can filter impurities in the air, the one-way valve 1 is connected to the inner wall of the exhaust channel, the one-way valve 1 allows the air in the exhaust channel to enter the limiting hole, the one-way valve 2 is connected to the inner wall of the air supply channel, and the one-way valve 2 allows outside air to enter the air supply channel.

[0015] By adopting the above technical scheme, when the exhaust piston slides along the inner wall of the exhaust flow channel toward the limit seat, the air pressure in the exhaust flow channel increases, driving the air in the exhaust flow channel into the limit hole through the one-way valve 1; when the exhaust piston slides along the inner wall of the exhaust flow channel toward the direction away from the limit seat, the air pressure in the exhaust flow channel decreases, the exhaust flow channel is connected to the air supply flow channel, and the outside air enters the exhaust flow channel from the air supply flow channel through the one-way valve 2, realizing directional air supply to the exhaust flow channel and driving the air flow around the limit seat, so that the limit seat is fully in contact with the air and heat exchange is carried out, so that the limit seat is not easy to heat up during long-term operation, thereby improving the stability of the operation of the underground pipeline laying equipment.

[0016] Optionally, the limit seat is connected to a heat dissipation component, which includes a heat dissipation piston. The inner wall of the air supply channel is provided with a heat dissipation channel for the heat dissipation piston to slide, and the sliding direction of the heat dissipation piston and the axis of the limit screw are parallel to each other.

[0017] By adopting the above technical solution, the heat dissipation channel is connected to the air supply channel. When the heat dissipation piston slides along the heat dissipation channel toward the air supply channel, the air in the heat dissipation channel is driven into the exhaust channel through the air supply channel. When the heat dissipation piston slides along the heat dissipation channel toward the direction away from the air supply channel, the outside air is driven into the air supply channel through the second one-way valve, thereby ensuring the air flow in the air supply channel, thereby improving the cooling efficiency of the limit seat.

[0018] Optionally, the heat dissipation assembly also includes a thermal expansion and contraction plate, a contact switch, a heat dissipation motor and a heat dissipation screw.

When the thermal expansion and contraction plate heats up and expands, the contact switch abuts the thermal expansion and contraction plate and is turned on, and the heat dissipation motor is energized and runs.

[0019] By adopting the above technical scheme, the end of the thermal expansion and contraction plate is connected to the surface of the heat dissipation channel close to the limiting hole. When the end of the rotating shaft of the winding roller is in rolling contact with the inner wall of the limiting hole for a long time and converts part of the kinetic energy into thermal energy, the inner wall of the limiting hole heats up, and the inner wall of the limiting hole transfers part of the thermal energy to the thermal expansion and contraction plate. The thermal expansion and contraction plate heats up and expands, the contact switch abuts the thermal expansion and contraction plate and is turned on, the heat dissipation motor is energized and runs, and the directional start of the heat dissipation motor is realized. The heat dissipation motor does not need to be in operation all the time, which reduces the loss of energy, thereby reflecting the concept of energy saving.

[0020] Optionally, the heat dissipation component also includes a heat conducting plate, and the inner wall of the limiting hole is provided with a heat conducting cavity for the heat conducting plate to be embedded, the surface of the heat conducting plate is in rolling contact with the end of the rotating shaft of the winding roller, the heat conducting cavity is connected to the heat dissipation channel, and the end of the heat conducting plate away from the limiting hole is connected to the surface of the thermal expansion and contraction plate.

[0021] By adopting the above technical solution, one end of the heat conducting plate is in rolling contact with the end of the rotating shaft of the winding roller, and the other end of the heat conducting plate is connected to the surface of the thermal expansion and contraction plate. When the winding roller rotates for a long time and converts part of the kinetic energy into thermal energy, the heat conducting plate transfers the thermal energy to the thermal expansion and contraction plate, and the thermal expansion and contraction plate heats up and expands, thereby ensuring the stability of the thermal expansion and contraction plate.

[0022] Optionally, the heat dissipation piston separates the heat dissipation channel into heat dissipation section one and heat dissipation section two, the heat dissipation section one is connected to the air supply channel, the heat dissipation section two has a pressure-stabilizing channel on its inner wall, and the pressure-stabilizing channel penetrates the outer wall of the limit seat in the depth direction.

[0023] By adopting the above technical scheme, when the heat dissipation piston slides in the direction close to the heat dissipation section one, the air in the heat dissipation section one enters the air supply channel, and at the same time, the outside air enters the heat dissipation section two through the pressure-stabilizing channel; when the heat dissipation piston slides in the direction close to the heat dissipation section two, the outside air enters the air supply channel after being filtered by the filter plate, and at the same time, the air in the heat dissipation section one is discharged through the pressure-stabilizing channel, thereby ensuring the stability of the air pressure in the heat dissipation channel, making it difficult for the heat dissipation motor to operate under high pressure and suffer loss, thereby improving the service life of the underground pipeline laying equipment.

[0024] Optionally, the heat dissipation component further includes a cleaning pipe, one end of which is connected to the surface of the limit seat and connected to the pressure-stabilizing flow channel, and the other end of the cleaning pipe faces the filter plate surface.

[0025] By adopting the above technical solution, when the air pressure in the heat dissipation section two increases, the air in the heat dissipation section two passes through the pressure-stabilizing flow channel and the inner cavity of the cleaning pipe in turn and impacts the filter plate surface. The air carries away impurities on the filter plate surface, realizing directional cleaning of the filter plate surface, thereby ensuring the stability of the filter plate in filtering the air.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The arrangement of the sliding seat, winding roller and limit assembly makes the length of the pipeline wound on the winding roller unlimited, which can meet the needs of laying different pipelines, thereby improving the practicality of underground pipeline laying equipment; 2. The setting of the limit screw and hand wheel can realize the precise control of the sliding height of the limit assembly on the sliding seat, thereby improving the convenience of using the underground pipeline laying equipment; 3. The setting of the limit seat, the clamping seat and the elastic member, the inner wall of the limit hole is pressed against the outer peripheral surface of the rotating shaft of the winding roller to form a limit, so that the end of the rotating shaft of the winding roller is not easy to separate from the limit seat and the clamping seat, thereby improving the limit stability of the winding roller on the limit seat.

One end of the heat conduction plate 66 is in rolling contact with the end of the rotating shaft of the winding roller 31, and the other end of the heat conduction plate 66 is fixed on the surface of the thermal expansion and contraction plate 62. The thermal expansion and contraction plate 62 is located on the side of the heat dissipation motor 64 away from the heat dissipation section 1 3514, and the contact switch 63 is electrically connected to the heat dissipation motor 64; when the winding roller 31 rotates for a long time and converts part of the kinetic energy into When the heat energy is converted into heat energy, the heat conducting plate 66 transfers part of the heat energy to the thermal expansion and contraction plate 62, the thermal expansion and contraction plate 62 heats up and expands, the contact switch 63 abuts against the thermal expansion and contraction plate 62 and is turned on, the heat dissipation motor 64 is energized and runs; when the heat dissipation piston 61 slides along the axis of the heat dissipation screw rod 65 toward the direction close to the air supply channel 3512, the air pressure in the air supply channel 3512 increases, and the air in the air supply channel 3512 passes through the exhaust channel 3511 and the one-way valve 54 in turn and enters the limiting In the positioning hole 3518, the air fully contacts the inner wall of the limiting hole 3518 and exchanges heat, thereby cooling the inner wall of the limiting hole 3518, so that the inner wall of the limiting hole 3518 is not easily worn out due to long-term operation under high temperature conditions. At the same time, the outside air passes through the cleaning pipe 67 and the pressure-stabilizing flow channel 3516 in turn and enters the heat dissipation section 2 3515, so that the heat dissipation motor 64 is operated under constant pressure conditions, ensuring that the heat dissipation motor 64 is not easily worn out due to low pressure conditions. When the heat dissipation piston 61 slides along the axis of the heat dissipation screw 65 toward the limiting hole 3518, the air pressure in the air supply flow channel 3512 decreases, and the outside air enters the air supply flow channel 3512 after being filtered by the filter plate 56 through the one-way valve 2 55. At the same time, the air in the heat dissipation section 2 3515 is ejected from the pipe mouth of the cleaning pipe 67 through the pressure-stabilizing flow channel 3516 and impacts the surface of the filter plate 56, taking away impurities on the surface of the filter plate 56, thereby achieving directional cleaning of the surface of the filter plate 56.

The elastic force of the elastic member 353 drives the abutting seat 352 to slide in the direction away from the limiting seat 351, and the limiting seat 351 and the abutting seat 352 are spliced ​​to form a The limiting hole 3518, the inner wall of the limiting hole 3518 presses against the outer peripheral surface of the rotating shaft of the winding roller 31 to form a limit, so that the end of the rotating shaft of the winding roller 31 is not easy to separate from the limiting seat 351 and the pressing seat 352, thereby improving the limiting stability of the winding roller 31 on the limiting seat 351; at the same time, according to the winding thickness of the pipeline on the roller surface of the winding roller 31, the handgrip 33 is manually grasped and the limiting screw rod 32 is driven to rotate, driving the limiting seat 351 to slide on the inner wall of the limiting flow channel 341, so that the winding roller 31 is located at the specified position on the sliding seat 34, and the pipeline wound on the winding roller 31 is not easy to abut against the top surface of the base 1, reducing the wear between the pipeline and the base 1, thereby improving the stability of the underground pipeline laying, and making the length of the pipeline wound on the winding roller 31 unlimited, which can meet the needs of laying different pipelines, thereby improving the practicability of the underground pipeline laying equipment.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
