Description

Technical Field

[0002] Municipal pipes refer to the pipe systems used for conveying public facilities such as water, sewage, natural gas, and heat in cities or municipal areas. These pipe systems are important components of urban infrastructure, ensuring the normal daily life of residents and the normal operation of the city.

[0003] In the prior art, such as Chinese Patent No.: CN220388053U, a pipe cutting device for municipal pipe construction, which relates to the technical field of pipe cutting, includes a mounting plate. Fixed frames are installed at the top of the left and right ends of the mounting plate. A first clamping sleeve is installed at the lower end inside the fixed frame. A movable bar is slidably connected inside the fixed frame. A second clamping sleeve is connected to the bottom of the movable bar. A limiting rod is arranged between the fixed frames. A movable frame is slidably connected to the upper end of the mounting plate. A support clamping sleeve is installed at the middle position of the top of the movable frame. Connecting plates are connected to the positions near the front and rear ends of the top of the movable frame. For this pipe cutting device for municipal pipe construction, scale lines are arranged at the top of the front end of the mounting plate. A connecting block is installed at the position near the front end on the left side of the movable frame. The left end of the connecting block is connected to a pointer, and the pointer is close to the scale line, which is convenient for accurately adjusting the position of the movable frame. By turning the knob, the second lead screw cooperates with the threaded sleeve, and the pressing block can move towards the mounting plate, thereby fixing the position of the movable frame and improving the cutting accuracy.

[0004] Although the above solution has the above advantages, the disadvantages of the above solution are that when the traditional pipe cutting device clamps the pipe, it can only fix the pipe for single clamping. When cutting the pipe, it cannot convey the pipe while clamping, which is not convenient for better cutting operations. And when clamping, it cannot be adjusted and fixed according to the pipe specifications, which affects the pipe cutting quality, reduces the overall efficiency of pipe cutting, and when performing cutting operations, it is necessary to cool the pipe. Due to the shortage of water resources, the water resources used for cooling cannot be recycled, which is very wasteful of water resources and reduces the practicability of the pipe cutting device.

[0022] 1. In the present utility model, first, the pipeline to be processed is horizontally placed at the center of the circular groove, and the part to be cut is exposed. At the same time, the long knob is manually rotated to make the long knob start to rotate forward. As the long knob continues to rotate, the circular plate also rotates. At this time, the whole pin has been in the pulled-out state. While the circular plate rotates, the circular gear on one side of the circular plate also starts to rotate. Through the continuous rotation of the circular gear, the hollow gear also starts to rotate forward. At this time, multiple clamping plates also perform circular motion accordingly, and gradually push multiple sliding blocks towards the pipeline. At the same time, the connecting block limits the sliding blocks to prevent them from deviating from the movement track. At this time, multiple pulleys start to firmly clamp the pipeline. Then, the pin is quickly released, and the pin is buckled in the circular plate to limit the whole circular plate. Subsequently, the other end of the pipeline is placed between the two clamping plates. Then, the circular knob is manually rotated. Through the continuous rotation of the circular knob, the bidirectional threaded rod starts to rotate forward and drives the two clamping plates to move towards the surface of the pipeline and firmly clamp the other end of the pipeline.

While the pipeline is moving, multiple pulleys convey the pipeline by their own characteristics, so as to achieve the effect of clamping and conveying while cutting the pipeline, which is convenient for better cutting operation, and is convenient for adjusting and fixing according to the pipeline specifications during clamping, ensuring the pipeline cutting quality and improving the overall efficiency of pipeline cutting.

[0023] 2. In the present utility model, when using the laser cutting assembly for cutting operation, the staff will turn on the external power supply of the liquid pump at the same time and start the liquid pump by using the controller. At this time, the inside of the water storage tank is filled with water.

At this time, the valve of the multi-tube nozzle is opened, and the water is evenly sprayed on the required cutting part by the multi-tube nozzle for cooling treatment. When the water source after the first treatment flows into the water storage tank, the water source is filtered by the filter plate, so that the water converges at the bottom of the water storage tank.

A circular plate 121 is movably connected to the other side of the outer surface of the fixing plate 113. One side of the outer surface of the circular plate 121 is fixedly connected to one side of the circular gear 114. A long plate 122 is fixedly connected to the other side of the outer surface of the fixing plate 113. A pin 123 is movably embedded in the long plate 122. One side of the outer surface of the pin 123 is fixedly connected to a spring 124. One end of the spring 124 is fixedly connected to one side of the long plate 122. A long knob 125 is fixedly connected to one side of the outer surface of the circular plate 121. Threaded lead screws 109 are movably connected to both sides of the inner wall of the bottom plate 1. Limiting grooves 112 are opened on both sides of the inner wall of the bottom plate 1. A moving plate 102 is threadedly connected to the outer surface of the threaded lead screw 109. Both sides of the outer surface of the moving plate 102 are movably embedded in the inner walls of the two limiting grooves 112. A heightening block 108 is fixedly connected to the center of the top of the moving plate 102. A square plate 103 is fixedly connected to the top end of the heightening block 108. A bidirectional threaded rod 107 is movably connected to the inside of the square plate 103. A circular knob 104 is fixedly connected to the top end of the bidirectional threaded rod 107. Two clamping plates 106 are threadedly connected to the outer surface of the bidirectional threaded rod 107. A limiting post 105 is fixedly connected to the inside of the square plate 103. The inside of the two clamping plates 106 is movably sleeved on the outer surface of the limiting post 105. A motor 111 is fixedly installed on one side of the outer surface of the bottom plate 1. The output end of the motor 111 is fixedly connected to one end of the threaded lead screw 109. A plurality of support legs 101 are fixedly connected to the bottom of the bottom plate 1.

[0034] In this embodiment, first, the pipeline to be processed is horizontally placed at the center of the circular groove 120, and the part to be cut is exposed. At the same time, the long knob 125 is manually rotated to make the long knob 125 start to rotate forward. As the long knob 125 continues to rotate, the circular plate 121 also rotates. At this time, the whole of the pin 123 has been in the pulled-out state. While the circular plate 121 rotates, the circular gear 114 on one side of the circular plate 121 also starts to rotate. Through the continuous rotation of the circular gear 114, the hollow gear 115 also starts to rotate forward. At this time, multiple clamping plates 106 also perform circular motion accordingly, and gradually push multiple sliding blocks 118 towards the pipeline. At the same time, the connecting block 117 limits the sliding blocks 118 to prevent them from deviating from the movement track. At this time, multiple pulleys 119 start to firmly clamp the pipeline. Then, the pin 123 is quickly released, and the pin 123 is buckled in the circular plate 121 to limit the whole circular plate 121. Subsequently, the staff places the other end of the pipeline between two clamping plates 106. Then, the circular knob 104 is manually rotated. Through the continuous rotation of the circular knob 104, the bidirectional threaded rod 107 starts to rotate forward, and drives the two clamping plates 106 to move towards the surface of the pipeline and firmly clamp the other end of it. While the two clamping plates 106 are moving, the limiting column 105 limits the two clamping plates 106 to prevent the clamping plates 106 from idling. When one end of the required pipeline is cut by the laser cutting assembly 204, the staff turns on the external power supply of the first motor 111 and starts the first motor 111 by using the controller. The output end of the first motor 111 starts to drive the threaded lead screw 109 to rotate forward. Through the continuous rotation of the threaded lead screw 109, the threaded lead screw 109 gradually drives the whole moving plate 102 and the pipeline to move horizontally. While the pipeline is moving, multiple pulleys 119 use their own characteristics to convey the pipeline, so as to achieve clamping and conveying during pipeline cutting, which is convenient for better cutting operations, and during clamping, it is convenient to adjust and fix according to the pipeline specifications, ensuring the pipeline cutting quality and improving the overall efficiency of pipeline cutting.

[0035] Embodiment 2, as Figures 1 - 6 shown, a water storage tank body 2 is fixedly connected to the bottom of the bottom plate 1, a cross plate 203 is fixedly connected to the top of the bottom plate 1 near the edge, a multi-tube nozzle 206 is fixedly installed at the bottom of the cross plate 203 near the edge, two sides of the inner wall of the water storage tank body 2 are slidably connected with a filter plate 202, one side of the filter plate 202 is connected with a pull-out plate 201 through a seal, a liquid pump 205 is fixedly installed on one side of the water storage tank body 2, the input end of the liquid pump 205 is fixedly embedded inside the water storage tank body 2, and the output end of the liquid pump 205 is connected to the inside of the multi-tube nozzle 206 through a hose. A laser cutting assembly 204 is fixedly installed at the bottom of the cross plate 203.

[0036] In this embodiment, when using the laser cutting assembly 204 for cutting operations, the operator will simultaneously turn on the external power supply of the liquid pump 205 and start the liquid pump 205 using the controller. At this time, the interior of the water storage tank 2 is filled with water. The input end of the liquid pump 205 begins to extract the water source from the water storage tank 2 and convey it to the multi-tube nozzle 206. At this time, the valve of the multi-tube nozzle 206 is opened, and the water is evenly sprayed onto the required cutting part using the multi-tube nozzle 206 for cooling treatment. When the water source after the first treatment flows into the water storage tank 2, the filter plate 202 is used to filter the water source, causing the water to collect at the bottom of the water storage tank 2. Then, the liquid pump 205 continuously conveys the water source to the multi-tube nozzle 206 for recycling the water resources. When it is necessary to replace the filter plate 202, the operator pulls out the pull-out plate 201 and replaces and washes the old filter plate 202, thereby achieving the recycling of the water resources used for cooling, saving water resources, and improving the practicality of the pipe cutting equipment.

[0037] Working principle: When in use, first place the pipeline to be processed horizontally at the center of the circular groove 120, and expose the part to be cut. At the same time, manually rotate the long knob 125 to make the long knob 125 start to rotate forward. As the long knob 125 continues to rotate, the circular plate 121 also rotates. At this time, the whole pin 123 has been in the pulled-out state. While the circular plate 121 rotates, the circular gear 114 on one side of the circular plate 121 also starts to rotate. Through the continuous rotation of the circular gear 114, the hollow gear 115 also starts to rotate forward. At this time, multiple clamping plates 106 also perform circular motion accordingly, and gradually push multiple sliding blocks 118 towards the pipeline. At the same time, the connecting block 117 limits the sliding block 118 to prevent it from deviating from the movement track. At this time, multiple pulleys 119 start to firmly clamp the pipeline. Then quickly release the pin 123, and use the pin 123 to snap into the circular plate 121 to limit the whole circular plate 121. Subsequently, the staff places the other end of the pipeline between two clamping plates 106, and then manually rotates the circular knob 104. Through the continuous rotation of the circular knob 104, the bidirectional threaded rod 107 starts to rotate forward, and drives the two clamping plates 106 to move towards the surface of the pipeline and firmly clamp the other end of it. While the two clamping plates 106 are moving, the limiting column 105 limits the two clamping plates 106 to prevent the clamping plates 106 from idling. When one end of the required pipeline is cut by the laser cutting assembly 204, the staff turns on the external power supply of the first motor 111 and uses the controller to start the first motor 111. The output end of the first motor 111 starts to drive the threaded lead screw 109 to rotate forward. Through the continuous rotation of the threaded lead screw 109, the threaded lead screw 109 gradually drives the whole moving plate 102 and the pipeline to move horizontally. While the pipeline is moving, multiple pulleys 119 use their own characteristics to convey the pipeline, so as to achieve clamping and conveying while cutting the pipeline, which is convenient for better cutting operations, and is convenient for adjusting and fixing according to the pipeline specifications during clamping, ensuring the pipeline cutting quality, improving the overall efficiency of pipeline cutting. And when using the laser cutting assembly 204 for cutting operations, the staff will also turn on the external power supply of the liquid pump 205 and use the controller to start the liquid pump 205. At this time, the inside of the water storage tank body 2 is filled with water. The input end of the liquid pump 205 starts to pump out the water in the water storage tank body 2 and convey it to the multi-tube nozzle 206. At this time, open the valve of the multi-tube nozzle 206, and use the multi-tube nozzle 206 to evenly spray water on the required cutting part for cooling treatment. When the water source after the first treatment flows into the water storage tank body 2, use the filter plate 202 to filter the water source, so that the water converges at the bottom of the water storage tank body 2, and then use the liquid pump 205 to continuously convey the water source to the multi-tube nozzle 206 for recycling of water resources. When it is necessary to replace the filter plate 202, the staff pulls out the pull-out plate 201 and replaces and washes the old filter plate 202.Thus, the water resources used for cooling can be recycled, which is very water-saving and improves the practicability of the pipe cutting equipment.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
