Technical Field

[0001] The present application relates to the field of tunnel construction, and in particular to a tool for quickly extruding a steel bar sleeve on a tunnel side wall. Background Art

[0002] During tunnel construction, it is usually necessary to extend two horizontally arranged connecting steel bars. The main operation process is to insert the two connecting steel bars to be connected into a special connecting sleeve, and use an extruder to radially extrude the sleeve to cause plastic deformation of the sleeve, and then embed it into the rib groove of the steel bar to achieve a firm connection between the two steel bars. This connection method is a type of mechanical connection, which has the advantages of fast construction speed and stable and reliable connection quality.

[0003] In the prior art, the equipment used to extrude steel sleeves usually includes a tunnel trolley, a pump station and an extrusion head connected to the pump station, wherein the pump station is placed on the tunnel trolley and is used to provide power to the extrusion head. When it is necessary to connect two butt-jointed connecting steel bars and connecting sleeves, the staff holds the extrusion head to the position of the connecting sleeve, places the connecting sleeve in the extrusion head, and extrude and fix the connecting sleeve through the extrusion head.

[0004] With respect to the above-mentioned prior art, when connecting the connecting sleeves and connecting steel bars at different positions, the staff needs to manually move the extrusion head to different extrusion positions, which is cumbersome to operate and has low work efficiency. Utility Model Content

[0005] In order to facilitate moving the extrusion head to different extrusion positions to achieve the extrusion connection between the connecting sleeve and the connecting steel bars and improve work efficiency, the present application provides a tooling for quickly extruding steel bar sleeves on tunnel side walls.

[0006] The present application provides a tool for quickly extruding a steel bar sleeve on a tunnel side wall, which adopts the following technical solution:

[0007] A tool for quickly extruding a steel sleeve on a tunnel side wall, comprising a fixed plate fixedly arranged on a tunnel trolley, an extrusion mechanism and a motion mechanism, wherein the extrusion mechanism comprises a pump station and an extrusion head connected to the pump station, and the motion mechanism comprises an x-axis motion component, a mounting seat, a y-axis motion component and a fixed seat, wherein the x-axis motion component is used to drive the mounting seat to move along the x-axis direction, the y-axis motion component is arranged on the mounting seat and is used to drive the fixed seat to move along the y-axis direction, and the fixed seat is used to fix the extrusion head.

[0008] By adopting the above technical solution, after the extrusion head is fixed to the fixed seat, the mounting seat and the fixed seat are driven to move along the x-axis and y-axis directions through the x-axis motion component and the y-axis motion component, so that the extrusion head can realize the extrusion connection between the connecting sleeve and the connecting steel bar at different extrusion positions. In this process, there is no need for the staff to manually apply force to move the extrusion head, which is easy to operate and conducive to improving work efficiency.

[0009] Optionally, the x-axis motion assembly includes an x-axis linear module disposed on a fixed plate, and the mounting seat is mounted on a slider of the x-axis linear module.

[0010] By adopting the above technical solution, the arrangement of the x-axis linear module makes the movement of the mounting seat along the x-axis direction convenient and stable.

[0011] Optionally, the mounting seat includes a first mounting portion, a vertical portion and a second mounting portion, the first mounting portion is used to place the pump station, the vertical portion is fixedly connected to the first mounting portion, the second mounting portion is fixedly mounted on the vertical portion, the y-axis motion assembly is arranged on the second mounting portion, the fixed plate is fixedly mounted on a guide rail, the guide rail is passed through the first mounting portion and slidably cooperates with the first mounting portion.

[0012] By adopting the above technical solution, when the mounting seat drives the extrusion head to move along the x-axis direction, the pump station moves along the x-axis direction with the mounting seat, so as to facilitate the stable provision of extrusion power to the extrusion head at different positions, and has strong applicability. In addition, the setting of the guide rail plays a further limiting role when the mounting seat moves, which is beneficial to fully ensure the stability of the mounting seat when it moves along the x-axis direction when the mounting seat carries heavier components.

[0013] Optionally, the y-axis motion assembly includes a y-axis screw, which is rotatably mounted on a mounting seat and arranged along the y-axis direction. The fixed seat is slidably engaged with the mounting seat along the y-axis direction. The y-axis screw is passed through the fixed seat and engaged with the fixed seat thread.

[0014] By adopting the above technical solution, when the y-axis screw rotates, the fixed seat moves along the y-axis direction due to the threaded cooperation with the y-axis screw and the sliding cooperation with the mounting seat. The setting of the y-axis screw makes the movement of the fixed seat in the y-axis direction convenient and stable.

[0015] Optionally, the y-axis motion assembly further includes a y-axis worm wheel and a y-axis worm, wherein the y-axis worm wheel is coaxially fixedly mounted on the y-axis lead screw, and the y-axis worm screw is rotatably mounted on the mounting seat and meshes with the y-axis worm wheel.

[0016] By adopting the above technical scheme, the setting of the y-axis worm wheel and the y-axis worm gear, on the one hand, reverses the rotation of the y-axis lead screw, making it easier to rotate the y-axis lead screw in a more advantageous position; on the other hand, the self-locking effect between the y-axis worm wheel and the y-axis worm gear is beneficial to ensuring the stability of the position of the fixed seat after moving along the y-axis direction.

[0017] Optionally, one end of the Y-axis worm is fixedly connected to a rotating handle.

[0018] By adopting the above technical solution, the setting of the rotating handle provides a rotating point for the staff to apply force to the rotation of the y-axis worm gear, thereby facilitating the application of force to realize the rotation of the y-axis worm gear.

[0019] Optionally, the fixed seat is provided with a clamping assembly, and the clamping assembly includes a positioning plate, a clamping plate and a clamping screw. The positioning plate is fixedly installed on the fixed seat, the clamping plate is arranged opposite to the positioning plate and is slidably engaged with the fixed seat along the x-axis direction, the clamping screw is rotatably installed on the fixed seat and is arranged along the x-axis direction, and the clamping screw is passed through the clamping plate and engaged with the clamping plate thread.

[0020] By adopting the above technical solution, when the clamping screw is rotated, the clamping plate moves along the x-axis direction toward or away from the positioning plate due to the threaded cooperation with the clamping screw and the sliding cooperation with the fixed seat. Therefore, when the extrusion head is located between the positioning plate and the clamping plate, it is convenient to press and fix the extrusion head through the movement of the clamping plate, thereby ensuring the stability of the position of the extrusion head when it is fixed to the fixed seat.

[0021] Optionally, abutment pads are fixedly provided on the opposite sides of the positioning plate and the clamping plate.

[0022] By adopting the above technical solution, the setting of the abutment pad plays a buffering role when the positioning plate and the clamping plate press and fix the extrusion head, so that the extrusion head is not easily damaged by rigid contact with the positioning plate and the clamping plate, which is beneficial to ensuring the service life of the extrusion head.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By driving the mounting seat and the fixing seat to move along the x-axis and y-axis directions through the x-axis motion component and the y-axis motion component, the extrusion head can realize the extrusion connection between the connecting sleeve and the connecting steel bar at different extrusion positions. In this process, the staff does not need to manually move the extrusion head, which is easy to operate and conducive to improving work efficiency.

[0025] 2. When the mounting seat drives the extrusion head to move along the x-axis direction, the pump station moves along the x-axis direction with the mounting seat, so as to stably provide extrusion power for the extrusion head at different positions, and has strong applicability. In addition, the setting of the guide rail plays a further limiting role when the mounting seat moves, which is beneficial to fully ensure the stability of the mounting seat when it moves along the x-axis direction when the mounting seat carries heavier parts.

[0026] 3. When the extrusion head is located between the positioning plate and the clamping plate, it is convenient to press and fix the extrusion head through the movement of the clamping plate, thereby ensuring the stability of the position of the extrusion head when it is fixed to the fixing seat.
