Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a positioning device for a hot-melt gasket for a tunnel waterproof membrane. Background Technology

[0002] On-site construction of tunnel waterproof membrane hot-melt gaskets typically involves manually measuring with a tape measure to determine the gasket positions. After marking, the gasket positions may have excessively large spacing and misaligned dimension lines, resulting in uneven distribution of the hot-melt gaskets. This, in turn, leads to wrinkles appearing on the surface of the EVA waterproof membrane during the hot-melt welding process.

[0003] The existing technology CN216523666U discloses a positioning device for hot-melt gaskets of tunnel waterproof membranes, including a support frame base, a rotating support frame, a dot matrix effect laser light, and a power supply CNC controller. The support frame base is fixed on a trolley for laying geotextile and waterproof membranes in the tunnel. The rotating support frame is installed on the support frame base and includes a rotating bracket and a bracket head. The bracket head is installed on the rotating bracket, and the dot matrix effect laser light is installed on the bracket head. The dot matrix effect laser light is connected to the power supply CNC controller. This device can realize the positioning of hot-melt gaskets for welding tunnel waterproof membranes.

[0004] However, the existing positioning device for hot melt gaskets of tunnel waterproof membranes can only adjust the angle of the dot matrix laser light, and cannot adjust the height position of the dot matrix laser light. This results in a limited range of adjustment for the laser irradiation position of the dot matrix laser light, leading to low flexibility of the positioning device. Therefore, further improvement is needed. Utility Model Content

[0005] To address the aforementioned issues, this application provides a positioning device for hot-melt gaskets used in tunnel waterproofing membranes.

[0006] The technical solution of the tunnel waterproof membrane hot melt gasket positioning device provided in this application is as follows: A positioning device for hot-melt gaskets of tunnel waterproof membrane includes a base, a movable plate that slides vertically, and a lifting adjustment assembly for adjusting the sliding position of the movable plate. The movable plate is equipped with a dot matrix laser light. The lifting adjustment assembly includes a vertical lead screw set on the base, a guide rod located on one side of the vertical lead screw, and an adjusting nut. The movable plate is slidably sleeved on the vertical lead screw and the guide rod. The adjusting nut is threaded onto the vertical lead screw and abuts against the lower end face of the movable plate.

[0007] By adopting the above technical solution, the height of the movable plate can be adjusted by rotating the adjusting nut relative to the vertical screw, thereby adjusting the height position of the dot matrix laser light, expanding the adjustment range of the laser irradiation position, and improving the flexibility of the positioning device.

[0008] Preferably, the vertical lead screw is rotatably connected to the base, and the lifting adjustment assembly further includes a support rod fixedly connected to the lower outer wall of the vertical lead screw, a guide rod fixedly connected to the side of the support rod away from the vertical lead screw, and the base is provided with a limiting component to restrict the vertical lead screw from rotating around its own axis.

[0009] By adopting the above technical solution, after the height of the movable plate is adjusted, the vertical lead screw is rotated to adjust the irradiation direction of the dot matrix laser light, and then the rotation of the vertical lead screw is restricted by the limiting component.

[0010] Preferably, the base is fixedly connected to a bearing seat, the bearing seat has a bearing body, the outer ring of the bearing body is fixed in the bearing groove of the bearing seat, and the lower part of the vertical lead screw is fixedly inserted into the inner ring of the bearing body.

[0011] By adopting the above technical solution, which involves setting a bearing seat in the base and fixing the outer ring of the bearing body to the bearing groove of the bearing seat, and fixing the lower part of the vertical lead screw to the inner ring of the bearing body, the frictional resistance when the vertical lead screw rotates can be reduced, making the vertical lead screw rotate more smoothly.

[0012] Preferably, a connecting shaft is fixedly inserted at the end of the movable plate away from the guide rod, the axis of the connecting shaft is parallel to the axis of the guide rod, and a connecting arm is fixedly connected to the connecting shaft, with a dot matrix laser light installed on the connecting arm.

[0013] Preferably, a connecting cylinder is fixedly connected to the end of the connecting arm, the dot matrix laser lamp is inserted into the inner cavity of the connecting cylinder, and a limiting screw is threaded onto the connecting cylinder, the limiting screw abutting against the outer wall of the dot matrix laser lamp.

[0014] By adopting the above technical solution, the dot matrix effect laser light is inserted into the inner cavity of the connecting cylinder, and the dot matrix effect laser light is pressed against the outer wall of the dot matrix effect laser light by the threaded locking limit screw, which can conveniently and stably install and fix the dot matrix effect laser light.

[0015] Preferably, the connecting arm is a metal-shaped flexible tube.

[0016] By adopting the above technical solution, the connecting arm uses a metal shaped flexible tube, which can be bent and shaped at will, making it convenient for staff to adjust the irradiation angle and direction of the dot matrix laser light according to actual needs, further improving the flexibility and applicability of the positioning device.

[0017] Preferably, the limiting component includes a pair of sliders located on both sides of the vertical lead screw and slidably connected to the base, a connecting rod fixedly connected to the sliders, a clamping plate fixedly connected to the end of the connecting rod, and a driving component for adjusting the sliding position of the sliders. The two clamping plates clamp and fix the vertical lead screw to limit its rotation.

[0018] By adopting the above technical solution, the slider, connecting rod, clamping plate and driving component work together to clamp and fix the vertical lead screw with two clamping plates, which can limit the rotation of the vertical lead screw and ensure the stability of the position of the dot matrix laser light after the height is adjusted.

[0019] Preferably, the upper surface of the base is provided with a sliding groove for the slider to slide. There are two sliding grooves, which are respectively located on both sides of the vertical lead screw. The driving component includes a bidirectional lead screw, which is rotatably connected to the inner wall of the sliding groove. The two sliders are respectively threaded onto the two threaded sections of the bidirectional lead screw.

[0020] By adopting the above technical solution, when the bidirectional lead screw is rotated, the two sliders can move synchronously and in opposite directions, causing the clamping plate to move closer to or away from the vertical lead screw, thereby achieving clamping and fixing or releasing the vertical lead screw, which facilitates restricting or allowing the rotation of the vertical lead screw.

[0021] Preferably, the driving component includes a telescopic cylinder and a hinge rod. The cylinder body of the telescopic cylinder is fixedly connected to the base, one end of the hinge rod is hinged to the slider or connecting rod, and the other end of the hinge rod is hinged to the piston rod of the telescopic cylinder.

[0022] By adopting the above technical solution, the piston rod of the telescopic cylinder extends and retracts, driving the hinge rod to rotate, which in turn pushes the slider to slide on the base, so that the two clamping plates clamp and fix the vertical screw to restrict the rotation of the vertical screw, thereby achieving effective control of the rotation of the vertical screw.

[0023] In summary, this utility model has the following beneficial effects: 1. By rotating the adjusting nut, the adjusting nut slides relative to the vertical lead screw, thereby adjusting the height of the movable plate, which in turn adjusts the height position of the dot matrix laser light, expanding the adjustment range of the laser irradiation position and improving the flexibility of the positioning device; 2. The connecting arm uses a metal shaped flexible tube, which can be bent and shaped at will, making it convenient for staff to adjust the irradiation angle and direction of the dot matrix laser light according to actual needs, further improving the flexibility and applicability of the positioning device; 3. Through the cooperation of slider, connecting rod, clamping plate and driving component, the two clamping plates clamp and fix the vertical lead screw, which can limit the rotation of the vertical lead screw and ensure the stability of the position of the dot matrix laser light after the height is adjusted.
