Description

Technical Field

[0001] This invention relates to the field of MPP pipe production and processing technology, and in particular to a multifunctional cooling device for the production of MPP power pipes. Background Technology

[0002] MPP power pipes use modified polypropylene as the main raw material and are characterized by high temperature resistance and external pressure resistance. They are divided into open-cut and trenchless types. Trenchless types do not require extensive dredging, excavation, or road surface damage during construction, making them widely used in special locations such as roads, railways, buildings, and riverbeds for laying pipelines and cables. The production process of MPP power pipes includes two steps: cooling and cutting. The pipe is shaped in a spray vacuum setting box and then cooled in a cooling mechanism. After cooling, the pipe temperature decreases, and it is then pulled to a cutting machine for cutting. Currently, MPP power pipes undergo only one cooling process during production, and the commonly used cooling method is immersion in a cooling water tank. This method involves directly immersing the high-temperature MPP power pipe in the cooling water tank, and the large temperature difference may damage the shape of the MPP power pipe. Furthermore, only one cooling process may result in insufficient and uneven cooling of the MPP power pipe, thus affecting its quality. Summary of the Invention

[0041] This embodiment is used to perform two cooling processes and cut the pipe removed from the spray vacuum setting box 1.

[0042] like Figures 1-5As shown, a multi-functional cooling device for the production of MPP power pipes includes a cooling device 2, a water tank 3, a cutting device 4, a support and transfer device 5, a picking device 6, and a control terminal 7. This embodiment has a front cooling section and a rear cooling section. The front cooling section includes one set of cooling devices 2, and the rear cooling section includes two sets of cooling devices 2. The front cooling section receives the pipe material removed from the spray vacuum setting box 1. Two water tanks 3 are provided, respectively located below the arched nozzles 202 in the front and rear cooling sections. A support plate is fixedly installed inside the water tank 3 in the front cooling section to support the forward movement of the pipe material. Both water tanks 3 have water outlets connected to water pipes for recycling used cooling water. The cutting device 4 is located between the front and rear cooling sections for cutting the pipe material. The support and transfer device 5 is located between the two sets of arched nozzles 202 in the rear cooling section for supporting the movement of the pipe material and transferring the cut pipe material. The picking device 6 is located at the rear end of the rear cooling section for removing the cut and cooled pipe material.

[0043] like Figures 6-17 As shown, the cooling device 2 includes a support frame 201, an arched nozzle 202, a connecting frame 203, a cleaning mechanism 204, and a moving component 205. The support frame 201 is installed on the ground. There are three arched nozzles 202, which are evenly distributed on the connecting frame 203. The left and right sides of the interior of the arched nozzle 202 are provided with several side spray holes, and the upper end is provided with several top spray holes. The arched nozzles 202 are connected to water pipes and are controlled to open and close by a solenoid valve. The connecting frame 203 is installed on the support frame 201. The cleaning mechanism 204 includes an arched movable frame 2041, side cleaning plates 2042, a top cleaning plate 2043, and a cleaning electric cylinder 2044. The arched movable frame 2041 is horizontally slidably mounted on the support frame 201 and can pass through all the arched nozzles 202. Two side cleaning plates 2042 are provided, and the two side cleaning plates 2042 are symmetrically arranged on the left and right sides inside the arched movable frame 2041. The top cleaning plate 2043 is located at the upper end inside the arched movable frame 2041. The side cleaning plate 2042 is provided with side spray hole cleaning columns corresponding to the side spray holes of the arched nozzle 202, and the top cleaning plate 2043 is provided with top spray hole cleaning columns corresponding to the top spray holes of the arched nozzle 202; the left and right sides of the arched moving frame 2041 are provided with side through holes corresponding to the side spray hole cleaning columns of the left and right side cleaning plates 2042 respectively, and the upper end of the arched moving frame 2041 is provided with a top through hole corresponding to the top spray hole cleaning column of the top cleaning plate 2043. Each side cleaning plate 2042 corresponds to four cleaning electric cylinders 2044. Each cleaning electric cylinder 2044 is installed on the inner side of the arched moving frame 2041, and its telescopic end is connected to one corner of the side cleaning plate 2042. The top cleaning plate 2043 corresponds to four cleaning electric cylinders 2044. Each cleaning electric cylinder 2044 is installed on the inner side of the arched moving frame 2041, and its telescopic end is connected to one corner of the top cleaning plate 2043. The moving component 205 includes a moving rack 2051, a moving gear 2052, a moving motor 2053, a transmission wheel 2054, and a transmission belt 2055. The moving rack 2051 is horizontally mounted on the arched moving frame 2041 along its sliding direction. Several moving gears 2052 are evenly distributed and rotatably mounted on the support frame 201 along the sliding direction of the arched moving frame 2041. All moving gears 2052 are synchronously connected by several transmission wheels 2054 and several transmission belts 2055. The moving motor 2053 is mounted on the support frame 201, and its output end is coaxially connected to one of the transmission wheels 2054. The moving rack 2051 intermittently meshes with each of the moving gears 2052. Figures 6-7 The diagram shows the installation method when the arched nozzle 202 and the connecting bracket 203 are located above the pipe. Figures 8-9 The diagram shows the installation method when the arched nozzle 202 and the connecting bracket 203 are located below the pipe; as shown Figures 4-5 As shown, the two sets of arched nozzles 202 in the two sets of cooling devices 2 at the rear of the cooling system are arranged symmetrically from top to bottom; Specifically, when cooling the pipe, cooling water is sprayed from the side and top nozzles of the arched nozzle 202 onto the pipe, and the flowing cooling water falls into the water storage tank 3. After cooling, the side and top nozzles of the arched nozzle 202 are cleaned and unblocked: the moving motor 2053 is started, driving all moving gears 2052 to rotate synchronously. The moving rack 2051 meshes with each moving gear 2052 in turn, thereby driving the arched moving frame 2041 to move on the support frame 201. The arched moving frame 2041 moves to the interior of the arched nozzle 202 that needs to be cleaned, and the cleaning electric cylinder 2044 is activated. The telescopic end of the cleaning electric cylinder 2044 on the top surface extends, driving the top surface... The cleaning plate 2043 moves outward, and the top surface spray nozzle cleaning column extends into the top surface spray nozzle through the top surface through hole. The telescopic end of the cleaning electric cylinder 2044 on the side retracts, driving the side cleaning plate 2042 to move outward. The side spray nozzle cleaning column extends into the side spray nozzle through the side through hole, thereby clearing and cleaning the top surface spray nozzle and the side spray nozzle. After all the arched nozzles 202 have been cleaned, the arched moving frame 2041 moves to the gap space between the two arched nozzles 202 to avoid affecting the subsequent spraying of the arched nozzles 202.

[0044] like Figures 18-19 As shown, the cutting device 4 includes a mounting frame 401, a rotating assembly 402, a rotating frame 403, and a cutter 404. The mounting frame 401 is mounted on the water tank 3 at the front of the cooling unit. The rotating frame 403 is rotatably mounted on the mounting frame 401, and the cutter 404 is mounted on the rotating frame 403. The rotating assembly 402 includes a rotating motor 4021 and a transmission gear set 4022. The rotating motor 4021 is mounted on the mounting frame 401, and its output end is coaxially connected to the input gear of the transmission gear set 4022. The input gear and the output gear of the transmission gear set 4022 mesh with each other. The output gear of the transmission gear set 4022 is rotatably mounted on the mounting frame 401, and the output gear is ring-shaped and fixedly connected to the rotating frame 403. The pipe can pass through the middle of the output gear, and the output gear can drive the rotating frame 403 to rotate. Specifically, the rotary motor 4021 is started, which drives the input gear of the transmission gear set 4022 to rotate, thereby driving the output gear to rotate. The output gear drives the rotating frame 403 to rotate, and the rotating frame 403 drives the cutter 404 to rotate. The cutter 404 is started, and the cutter 404 cuts the pipe while rotating around it.

[0045] like Figures 20-22 , Figure 25 As shown, the support and transfer device 5 includes a second support frame 501, support arms 502, a rotating assembly 503, and a flexible support frame 504. The second support frame 501 is installed on the ground. Four pairs of support arms 502 are evenly distributed along the direction of pipe movement on the second support frame 501. Each pair of support arms 502 is symmetrically arranged on the second support frame 501, and the bottom end of each support arm 502 is rotatably mounted on the second support frame 501. The rotating assembly 503 connects all the rotating nodes of the support arms 502 synchronously through several transmission gears, transmission wheels, transmission shafts, and transmission connecting belts. 03 also includes a rotating motor, which is mounted on the support frame 501, and its output end is coaxially connected to one of the transmission gears; the flexible support frame 504 is fixedly installed in the water storage tank 3 located at the rear of the cooling system, and is located inside the arched moving frame 2041 below the rear of the cooling system. The flexible support frame 504 does not affect the sliding of the arched moving frame 2041; the flexible support frame 504 is U-shaped and made of flexible plastic, which can effectively buffer the falling impact of the pipes, thereby protecting other devices from damage. In addition, the flexible support frame 504 is provided with cooling water through holes, which will not affect the spraying of cooling water. Specifically, when each pair of support arms 502 points upward, they are used to support the movement of the pipe. When the rotating motor is started, all support arms 502 are driven to rotate synchronously in opposite directions through the transmission gear, transmission wheel, transmission shaft and transmission connecting belt. Each support arm 502 rotates outward, and the cut pipe is lowered and falls into the flexible support frame 504. The flexible support frame 504 not only avoids direct contact between the pipe and the arched moving frame 2041 and the arched nozzle 202, which would affect the cooling effect, but also effectively acts as a buffer when the pipe falls.

[0046] like Figures 23-24 As shown, the picking device 6 includes a support frame 601, a drive screw 602, a sliding frame 603, a transfer motor 604, an L-shaped support rod 605, an adjusting screw 606, a slider 607, a connecting rod 608, and a friction support block 609. The support frame 601 is fixedly installed on the ground. The drive screw 602 is horizontally installed on the support frame 601 and is parallel to the direction of movement of the pipe. The sliding frame 603 is slidably installed on the drive screw 602 and is slidably connected to the support frame 601. The transfer motor 604 is fixedly installed on the sliding frame 603, and its output end is coaxially connected to the vertical rod of the L-shaped support rod 605. The adjusting screw 606 is horizontally mounted on the crossbar of the L-shaped support rod 605. The adjusting screw 606 has three sets of bidirectional threads along a straight line. Two sliders 607 are symmetrically slidably mounted on each set of bidirectional threads, and each set of bidirectional threads corresponds to two friction support blocks 609. Each friction support block 609 is connected to the two sliders 607 on the corresponding bidirectional thread through two connecting rods 608. One end of each connecting rod 608 rotates on the corresponding friction support block 609, and the other end rotates on the corresponding slider 607. Specifically, the drive screw 602 is activated, causing the sliding frame 603 to move towards the pipe, and the crossbar of the L-shaped support rod 605 extends into the cut pipe. The adjusting screw 606 is activated, causing each set of bidirectional threads to move the corresponding two sliders 607 closer together. The two sliders 607, through the corresponding connecting rod 608, move the two friction support blocks 609 away from each other, and all the friction support blocks 609 work together to support the pipe. The drive screw 602 causes the sliding frame 603 to move in the opposite direction to the initial position. The transfer motor 604 is activated, causing the L-shaped support rod 605 to rotate 45°, thereby causing the pipe to rotate 45°. The adjusting screw 606 is reversed, causing the two sliders 607 on each set of bidirectional threads to move away from each other, and the corresponding two friction support blocks 609 to move closer together, thereby releasing the pipe. The operator removes the pipe, and the transfer motor 604 causes the L-shaped support rod 605 to return to its original position.

[0047] like Figure 26As shown, the control terminal 7 includes a main controller, a human-machine interface display screen, an information transmission module, a storage module, and a power supply module. The main controller is electrically connected to the human-machine interface display screen, the information transmission module, the storage module, the power supply module, as well as the solenoid valve, the cleaning cylinder 2044, the moving motor 2053, the rotating motor 4021, the cutter 404, the rotating motor, the drive screw 602, the transfer motor 604, and the adjusting screw 606. The main controller is used to control the operation of the entire multi-functional cooling equipment. The human-machine interface display screen is used to set the working time and pipe length, as well as the automatic operation control after the set values ​​are determined. The information transmission module is used for information transmission between the main controller and the cooling device 2, the cutting device 4, the support and transfer device 5, and the picking device 6. The power supply module is used to provide a stable power supply to the control terminal 7. The storage module is used to store the operation information data of the entire multi-functional cooling equipment.

[0048] The cooling device 2, support and transfer device 5, and picking device 6 in the figure of this embodiment are for illustrative purposes only. Their specific lengths need to be set according to the actual engineering requirements.

[0049] The working steps of this embodiment are as follows: Step 1: Activate the solenoid valve of the arched nozzle 202 at the front of the cooling section. The arched nozzle 202 sprays cooling water onto the pipe that has been removed from the spray vacuum setting box 1. The pipe continues to move forward through the rotating frame 403 and onto the support arm 502. Step 2: When the length of the pipe passing through the rotating frame 403 reaches the set value, start the rotating motor 4021 and the cutter 404. The rotating frame 403 drives the cutter 404 to rotate, and the cutter 404 cuts the pipe. Step 3: Activate the solenoid valve of the arched nozzle 202 located at the top of the cooling section, and the arched nozzle 202 sprays cooling water onto the cut pipe. Step 4: Start the rotating motor, and all support arms 502 rotate outward synchronously, lowering the cut pipe into the flexible support frame 504; activate the solenoid valve of the lower arched nozzle 202, and the arched nozzle 202 sprays cooling water onto the pipe; Step 5: Start the drive screw 602, and the L-shaped support rod 605 extends into the pipe; start the adjusting screw 606, and the friction support block 609 supports the pipe; the drive screw 602 moves the L-shaped support rod 605 back to its original position, and the transfer motor 604 is started, which rotates the L-shaped support rod 605 clockwise by 45°. The operator removes the pipe, and the transfer motor 604 then moves the L-shaped support rod 605 back to its original position. Step 6: After all pipes have been cut and cooled, start all the moving motors 2053 to drive the corresponding arched moving frames 2041 to move into the interior of each arched nozzle 202 in turn; each time the arched moving frame 2041 moves into the interior of an arched nozzle 202, start all the cleaning electric cylinders 2044 on it to clean and unclog the side spray holes and top spray holes of the arched nozzle 202 until all arched nozzles 202 are cleaned; the arched moving frame 2041 moves between two arched nozzles 202; The above steps complete the cutting and cooling of the MPP power pipe and clean and unclog the nozzles of the arched nozzle 202.
