Description

Technical Field

[0001] This utility model relates to a pipe end processing device, specifically a thermal insulation pipe end cutting processing device. Background Technology

[0002] Currently, the cutting of the insulation pipe ends is often done manually. A handheld cutting saw is used to cut the PE and PU layers at the pipe ends, and after manual removal, a handheld grinding roller is used to polish the outer surface of the steel pipe ends. This method is labor-intensive, inefficient, involves harsh working conditions, and poses significant safety hazards. Summary of the Invention

[0003] To address the problems of high labor costs, low efficiency, harsh working environment, and significant safety hazards associated with existing methods of cutting and processing the ends of insulated pipes, this invention provides an insulated pipe end cutting and processing device. This device has a simple and compact structure, low maintenance costs, and can simultaneously cut and grind both ends of the insulated pipe, thus effectively solving many problems existing in traditional manual methods.

[0004] The present invention adopts the following technical solution:

[0005] A thermal insulation pipe end cutting and processing device includes a cutting and grinding assembly, and two cutting processing devices symmetrically arranged at both ends of the thermal insulation pipe. A tire-rolling mechanism for rotating and positioning the thermal insulation pipe is distributed between the cutting processing devices. The two cutting processing devices are respectively mounted on a traveling trolley of a ground track assembly extending along the axial direction of the thermal insulation pipe. The traveling trolley has a vertical frame structure. Each cutting processing device includes: a pipe end positioning assembly, a cutting and grinding assembly, a probe assembly, and a plastic film wrapping assembly. The pipe end positioning assembly is located on the ground adjacent to the cutting processing device. A lifting cylinder extending upwards is fixedly installed within the vertical frame structure of the traveling trolley. The lifting cylinder extends and retracts to raise and lower a lifting support. A working support is slidably mounted on one side of the lifting support. A grinding and lifting cylinder is connected to the lifting support and the working support, driving the working support to rise and fall. The cutting and grinding assembly is mounted on the working support and includes a cutting saw driven by a cutting saw drive motor.

[0006] The cutting and grinding assembly also includes: a rotary reducer, a hydraulic motor, a grinding roller, a grinding roller drive motor, a lifting servo motor, a coupling, a ball screw, a transition plate, a lifting slide plate, a lifting shaft, and a lifting guide frame. The grinding roller drive motor drives and connects to the grinding roller. The rotary reducer is fixedly connected to the bottom of the working bracket. The rotary reducer is connected to the transition plate. The lifting servo motor is mounted above the transition plate, and the lifting guide frame is mounted below the transition plate. The hydraulic motor drives the rotary reducer. The lifting servo motor is connected to the ball screw through a coupling. The nut on the ball screw is fixed to the lifting shaft. The lifting shaft passes through the lifting slide plate, which is equipped with four sliders. The lifting guide frame is equipped with guide rails. The cutting saw drive motor is fixed to the lifting slide plate through a cutting saw mounting bracket, and the grinding roller drive motor is fixed to the lifting slide plate through a grinding roller mounting bracket.

[0007] The tire swirl mechanism includes: a driving tire and a driven tire, with the driving tire and / or driven tires arranged symmetrically at intervals.

[0008] The pipe end positioning assembly includes: a positioning cylinder, a positioning roller, and a positioning roller guide channel. The two positioning roller guide channels form a track component, which contains a trolley driven by the positioning cylinder for linear displacement. A vertical structural component is installed on the trolley, and the structural component is equipped with a vertical positioning roller. The positioning cylinder drives the positioning roller to move laterally.

[0009] The probe assembly is mounted on the working support, located below the cutting and grinding assembly. The probe assembly includes: a probe roller, a probe roller connecting shaft, a probe roller coupling, an encoder, bearings, a magnetic ring, a displacement sensor, a probe lifting guide rod cylinder, and a probe translating guide rod cylinder. The probe translating guide rod cylinder is horizontally fixed to the working support. A guide rod is provided on the cylinder to prevent rotation. A probe lifting guide rod cylinder is vertically fixed at the end of the rod, with the rod end facing upwards. A fork lug is provided at the rod end, and the probe roller connecting shaft is installed inside the fork lug. The probe roller is fixed to the probe roller connecting shaft. Bearings are mounted on both sides of the probe roller connecting shaft. An encoder is installed on the outside of one end of the shaft of the fork lug. The probe roller connecting shaft is connected to the encoder via the probe roller coupling. A magnetic ring is fixed to the fork lug via a connecting piece. A displacement sensor is installed in the cylinder body of the probe lifting guide rod cylinder, and the probe rod of the displacement sensor extends into the magnetic ring.

[0010] The plastic film wrapping assembly includes: a moving module, a slide block, a moving module drive motor, a packing machine, and a plastic film. The moving module drive motor drives the slide block on the moving module to move, which in turn moves the packing machine fixed on the slide block. The packing machine has rollers on which the plastic film is wrapped.

[0011] The track assembly is equipped with a rack, and the traveling trolley is driven by a traveling drive motor on the rack to make the gear roll on the rack, thereby enabling the traveling trolley to move on the track assembly.

[0012] The upper main structure of the active tire is equipped with a tire drive motor connected to the tire via a connecting shaft. The rotation of the tire drive motor drives the tire to rotate. A sliding and adjustable dovetail rail is set between the upper and lower main structures of the active tire, and the upper main structure slides to adjust the tire spacing.

[0013] Compared with the prior art, the present invention can achieve the following technical effects:

[0014] 1. The insulation pipe is positioned by using a hydraulic cylinder to drive the positioning rollers on both sides, ensuring that the insulation pipe will not move axially during operation. This positioning method is reliable.

[0015] 2. A motor reducer is used to drive a tire placed below the insulation pipe to rotate, which in turn drives the insulation pipe to rotate to complete the cutting, grinding, and plastic film wrapping work at the end of the insulation pipe. This method can ensure that the insulation pipe rotates smoothly and the speed is controllable.

[0016] 3. The cutting and grinding components are driven by a hydraulic motor to achieve 90° and 180° rotation, enabling the switching of modes for circumferential cutting, longitudinal cutting, and grinding of the insulation pipe end. This method integrates the work of different modes into one, with a compact structure, smooth operation, and high efficiency.

[0017] 4. The ball screw is driven by a servo motor to rotate and move the cutting and grinding components fixed on the nut to rise and fall. This method is smooth and can effectively achieve precise control of the cutting depth.

[0018] 5. The grinding roller is pressed against the outer wall of the steel pipe at the end of the tube by the extension and retraction of the cylinder for grinding, which can achieve effective pressing of the grinding roller and the pressure is adjustable.

[0019] 6. A cylinder-driven probe assembly equipped with an encoder is used to raise and lower the probe to detect and control the distance between the cutting saw blade and the outer wall of the insulation pipe, thereby controlling the cutting allowance. At the same time, when the insulation pipe rotates, the encoder records the rotation angle of the insulation pipe, so as to set the number of longitudinal cuts of the insulation pipe.

[0020] 7. The cutting of the pipe ends of insulation pipes of different lengths is achieved by using a servo motor reducer to drive the gear to move on the rack. This method is stable and the data is reliable.

[0021] 8. The working support can be smoothly raised and lowered by a hydraulic cylinder equipped with a lifting displacement sensor to adapt to the pipe end cutting work of insulation pipes of different diameters.

[0022] 9. The use of a ball screw moving module to drive the plastic film wrapping assembly to move back and forth can effectively and smoothly wrap the cut and polished pipe ends with plastic film.

[0023] 10. The processing equipment is equipped with a high-pressure pulse dust collector, which can effectively reduce dust particles during operation and thus protect the working environment. Attached Figure Description
