Description

Technical Field

[0001] This invention relates to the field of polyethylene pipe handling technology, specifically to an automatic polyethylene pipe handling device. Background Technology

[0002] Polyethylene pipes have good heat and cold resistance, good chemical stability, and are relatively lightweight, making them widely used in urban and rural water supply pipelines, gas transmission pipelines, and other fields.

[0003] In the prior art, a utility model patent with publication number CN218987882U and titled "A Mining Polyethylene Pipe Conveying Device" includes a polyethylene pipe, a left support frame, and a right support frame. One side of the bottom surface of the polyethylene pipe is covered by the left support frame, and the other side of the bottom surface of the polyethylene pipe is covered by the right support frame. This utility model involves hoisting the polyethylene pipe to the inside of the left and right support frames, then placing an arc-shaped covering sleeve on the surface of the polyethylene pipe, and finally attaching the lugs at both ends of the covering sleeve to... The protruding pillars welded to the sides of the left or right carrier are hooked together, so that the rubber strip in the middle of the cover sleeve is tightly fitted to the polyethylene pipe until both the left and right carriers are fixed to both ends of the polyethylene pipe by the cover sleeve. At this time, by extending the two ends of the connecting rod to the fixing seat at the bottom of the left and right carriers respectively, the connecting rod is made to engage with the slots corresponding to the surface of the fixing seat. Then, the Phillips head knob is turned so that the Phillips head knob abuts against the connecting rod until the left and right carriers are formed into a whole for pipe transportation.

[0004] The equipment of this patent can transport polyethylene pipes of different lengths. However, the equipment of this patent still has the following defects in actual use: (1) When the equipment of this patent transports polyethylene pipes, the polyethylene pipes are placed horizontally. The polyethylene pipes occupy a large space during transportation, which makes it inconvenient for the equipment of this patent to transport polyethylene pipes in a narrow transportation space, thereby reducing the overall practicality of the equipment to a certain extent; (2) After the polyethylene pipes are transported to the designated location, the polyethylene pipes need to be laid out. However, the equipment of this patent cannot adjust the position of the polyethylene pipes after transportation, which increases the workload of the staff and makes it inconvenient to meet the different usage needs of users. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic handling device for polyethylene pipes.

[0006] The technical problem solved by this invention is:

[0007] (1) When the existing equipment transports polyethylene pipes, the polyethylene pipes are placed horizontally, which takes up a lot of space during transportation, making it inconvenient for the equipment to transport polyethylene pipes in a narrow transportation space.

[0008] (2) The existing equipment is inconvenient to adjust the position of polyethylene pipes after transportation to facilitate the laying of polyethylene pipes by users.

[0009] This invention can be achieved through the following technical solution: an automatic handling device for polyethylene pipes, including a movable base, with movable wheels fixedly installed at the bottom of the movable base. The movable wheels are brake wheels, and the movable base facilitates the overall movement of the equipment. A rotating plate is rotatably connected to the movable base, and a driving mechanism is provided on the movable base to drive the rotating plate to rotate 90 degrees. The driving mechanism includes a movable frame slidably connected to the movable base. An electric telescopic rod is fixedly connected to the movable base via a support plate. The output end of the electric telescopic rod is fixedly connected to the movable frame, and the movable frame is slidably driven to slide by connecting the power supply to the electric telescopic rod. A round rod slidably connected to the rotating plate is fixedly installed between the two inner side walls of the movable frame. Sliding the movable frame causes the round rod to slide in the inner cavity of the inclined groove, thereby causing the rotating plate to rotate.

[0010] The rotating plate is symmetrically slidably connected to a top pipe fixing sleeve and a bottom pipe fixing sleeve for fixing both ends of the polyethylene pipe. The movement of the top pipe fixing sleeve and the bottom pipe fixing sleeve facilitates the fixing of polyethylene pipes of different lengths and specifications. The inner cavity of the top pipe fixing sleeve is provided with a fixing mechanism for fixing the inner and outer walls of the polyethylene pipe. The fixing mechanism in the inner cavity of the top pipe fixing sleeve facilitates further fixing of the polyethylene pipe.

[0011] A further technical improvement of the present invention is that the fixing mechanism includes at least two outer clamping plates of the pipe that are floatingly connected to the inner cavity of the top pipe fixing sleeve, and the outer clamping plates of the pipe facilitate the limiting of the outer wall of the polyethylene pipe.

[0012] A further technical improvement of the present invention is that a telescopic component is provided between the outer clamping plate of the pipe and the inner cavity of the top pipe fixing sleeve. The telescopic component includes an outer sleeve fixedly connected to the inner cavity of the top pipe fixing sleeve, and an inner sleeve fixedly connected to the outer clamping plate of the pipe is elastically slidably connected to the inner cavity of the outer sleeve. The telescopic component facilitates the equipment to limit the outer wall of polyethylene pipes of different diameter specifications.

[0013] A further technical improvement of the present invention is that: a fixed cylinder is fixedly connected to the center of the inner cavity of the top pipe fixing sleeve, and at least two pipe inner clamping plates are symmetrically slidably connected to the side of the fixed cylinder away from the inner cavity of the top pipe fixing sleeve, and the inner cavity of the fixed cylinder is provided with a linkage component that causes the two pipe inner clamping plates to move relative to or in opposite directions.

[0014] A further technical improvement of the present invention is that: the linkage component includes a gear ring rotatably connected to the inner wall of the fixed cylinder, the gear ring is driven by a first motor, and the gear ring can be rotated by manually connecting the first motor; at least two gears meshing with the gear ring are rotatably connected to the inner wall of the fixed cylinder, and a rack meshing with the gears is slidably connected to the bottom end of the fixed cylinder, the rack is fixedly connected to the inner clamping plate of the pipe, and rotating the gear ring causes the gears to rotate synchronously.

[0015] A further technical improvement of the present invention is that: a centering mechanism is provided at the middle of one side of the rotating plate, the centering mechanism includes a second electric push rod symmetrically and fixedly connected to the middle of one side of the rotating plate, a V-shaped plate is fixedly connected to the output end of the second electric push rod, and an arc-shaped plate is fixedly installed on the side of the V-shaped plate away from the second electric push rod.

[0016] A further technical improvement of the present invention is that a trigger switch is fixedly installed on the movable base, abutting against the side wall of the rotating plate. The trigger switch is electrically connected to the second electric push rod, and the electric telescopic rod is also electrically connected to the trigger switch. After the rotating plate is rotated 90 degrees in the opposite direction, the side wall of the rotating plate will contact the trigger switch. At this time, the trigger switch will first disconnect the power supply of the electric telescopic rod, and then connect the power supply of the second electric push rod. By connecting the power supply of the second electric push rod, it is easy to release the V-shaped plate from the polyethylene pipe. Then, the tilt angle of the polyethylene pipe can be adjusted according to the user's needs. Adjusting its tilt angle facilitates the user's subsequent installation, thereby conveniently meeting the different user needs.

[0017] A further technical improvement of the present invention is that: the inner cavity of the rotating plate is provided with an adjustment mechanism that causes the top pipe fixing sleeve and the bottom pipe fixing sleeve to move relative to or in opposite directions. The adjustment mechanism includes a bidirectional screw rod rotatably connected to the inner cavity of the rotating plate. Nuts are threaded on the two external threads with opposite directions on the outer surface of the bidirectional screw rod. The nuts are slidably connected to the inner cavity of the rotating plate. The two nuts are fixedly connected to the top pipe fixing sleeve and the bottom pipe fixing sleeve, respectively. Rotating the bidirectional screw rod causes the two external threads with opposite directions on the bidirectional screw rod to rotate synchronously, thereby driving the two nuts on the bidirectional screw rod to move relative to or in opposite directions.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention uses the shortening of an electric telescopic rod to rotate the plate 90 degrees. This rotation facilitates better fixing of polyethylene pipes by the user. During fixing, the rotation of the bidirectional screw causes the two external threads with opposite directions to rotate synchronously, thereby driving the two nuts on it to move relative to or in opposite directions. The movement of the two nuts causes the top pipe fixing sleeve and the bottom pipe fixing sleeve to move synchronously, thus facilitating the fixing of polyethylene pipes of different lengths. After fixing, the extension of the electric telescopic rod causes the rotating plate to rotate 90 degrees in the opposite direction, so that the polyethylene pipes on the rotating plate can remain in an upright position. This reduces the space occupied by the polyethylene pipes during transportation, making it easier to transport polyethylene pipes in confined spaces and convenient for workers to use.

[0020] 2. In this invention, after the rotating plate is flipped 90 degrees in the opposite direction, the side wall of the rotating plate will press against the trigger plate. When the trigger plate is pressed, it will contact the trigger switch. At this time, the trigger switch will first disconnect the power supply of the electric telescopic rod and then connect the power supply of the second electric push rod. By connecting the power supply of the second electric push rod, it is easy to release the V-shaped plate from fixing the polyethylene pipe. Then, the tilt angle of the polyethylene pipe can be adjusted according to the user's needs. Adjusting its tilt angle facilitates the user's subsequent installation and thus meets the different needs of the user. Attached Figure Description

[0041] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0042] Please see Figure 1-3As shown, the automatic handling device for polyethylene pipes includes a movable base 1, on which a fixed frame 11 and a push handle 6 are fixedly connected. The push handle 6 is used to facilitate the user to push the movable base 1. The push handle 6 is engraved with anti-slip texture to facilitate the user's grip. The inner cavity of the fixed frame 11 is rotatably connected to a rotating plate 12 via a pin. An electric telescopic rod 14 is fixedly connected to the fixed frame 11 via a support plate. The output end of the electric telescopic rod 14 is fixedly connected to a movable frame 13 that cooperates with the fixed frame 11. The inner cavity of the fixed frame 11 has a sliding groove 4 for the movable frame 13 to slide. A round rod 15 is fixedly installed between the two inner side walls of the movable frame 13. The inner cavity of the rotating plate 12 has an inclined groove 5 that cooperates with the round rod 15.

[0043] Please see Figure 4 As shown, the inner cavity of the rotating plate 12 is provided with an inner groove 16. The inner cavity of the inner groove 16 is rotatably connected to a bidirectional screw 17 through a bearing. The side of the bidirectional screw 17 near the end is fixedly fitted with two external threads with opposite directions. Nuts 18 are threaded on both external threads of the bidirectional screw 17. The nuts 18 are slidably connected to the inner wall of the inner groove 16. The side of the two nuts 18 away from the inner wall of the inner groove 16 is rotatably connected to a top pipe fixing sleeve 19 and a bottom pipe fixing sleeve 110, respectively. The side of the top nut 18 on the bidirectional screw 17 is also rotatably connected to a first electric push rod 111. The output end of the first electric push rod 111 is rotatably connected to the top pipe fixing sleeve 19.

[0044] A second motor 112 is fixedly connected to the rotating plate 12, and the output end of the second motor 112 is fixedly connected to the bidirectional screw 17.

[0045] Please see Figure 5-6 As shown, the inner cavity of the top pipe fixing sleeve 19 is provided with a cylindrical groove 191. The inner wall of the cylindrical groove 191 is provided with at least two telescopic components 192. The telescopic component 192 includes an outer sleeve 1921 fixedly connected to the inner wall of the cylindrical groove 191. An inner sleeve 1923 is slidably connected to the inner cavity of the outer sleeve 1921. A pipe outer clamping plate 193 is fixedly connected to the side of the inner sleeve 1923 away from the inner cavity of the outer sleeve 1921. A compression spring 1922 is fixedly connected to the inner wall of the outer sleeve 1921. The side of the compression spring 1922 away from the inner wall of the outer sleeve 1921 is fixedly connected to the inner sleeve 1923.

[0046] Please see Figure 5 , 7As shown in Figure 8, a first motor 194 is fixedly installed on the inner wall of the cylindrical groove 191. A turntable 195 is fixedly connected to the output end of the first motor 194. A fixed cylinder 196 is fixedly installed on the inner wall of the cylindrical groove 191 and outside the first motor 194 via a fixed rod. A gear ring 197 fixedly connected to the turntable 195 is fixedly installed on the inner wall of the fixed cylinder 196. At least two gears 198 that mesh with the gear ring 197 are rotatably connected to the inner wall of the fixed cylinder 196 via a pin. At least two moving grooves are opened in the inner cavity of the fixed cylinder 196. A rack 199 that meshes with the gear 198 is slidably connected to the inner wall of the moving groove. A pipe inner clamping plate 1910 is fixedly installed on the side of the rack 199 away from the fixed cylinder 196.

[0047] Please see Figure 9-10 As shown, a connecting groove 2 is provided on the side of the fixed frame 11 opposite to the rotating plate 12. A transmission plate 21 is elastically slidably connected to the inner cavity of the connecting groove 2. A trigger plate 22 that abuts against the rotating plate 12 is fixedly connected to the side of the transmission plate 21 away from the inner cavity of the connecting groove 2. A trigger switch 23 corresponding to the transmission plate 21 is fixedly installed on the inner wall of the connecting groove 2.

[0048] Please see Figure 11-12 As shown, a pipe fixing mechanism is provided at the middle end of the rotating plate 12. The pipe fixing mechanism includes two connecting plates 3 symmetrically fixed at the middle end of the rotating plate 12. A second electric push rod 31 is fixedly installed on the opposite side of the two connecting plates 3. The electric telescopic rod 14 and the second electric push rod 31 are electrically connected to the trigger switch 23. A V-shaped plate 32 is fixedly connected to the output end of the second electric push rod 31. An arc-shaped plate 33 that cooperates with the V-shaped plate 32 is fixedly installed on the side of the V-shaped plate 32 away from the second electric push rod 31.

[0049] When in use, the user pushes the movable base 1 with the help of the push handle 6. After the movable base 1 moves to the designated working location, the power supply of the electric telescopic rod 14 is turned on to shorten the electric telescopic rod 14. The shortening of the electric telescopic rod 14 causes the movable frame 13 to slide in the sliding groove 4 in the inner cavity of the fixed frame 11. The sliding of the movable frame 13 causes the round rod 15 fixedly connected to it to move synchronously, thereby causing the rotating plate 12 to rotate 90 degrees. The rotation of the rotating plate 12 makes it easier for the user to fix the polyethylene pipe.

[0050] When fixing the polyethylene pipe, the distance between the top pipe fixing sleeve 19 and the bottom pipe fixing sleeve 110 can be adjusted according to the actual need to fix the length of the polyethylene pipe. During adjustment, the power supply of the second motor 112 is turned on to make the bidirectional screw 17 rotate. The rotation of the bidirectional screw 17 causes the two external threads with opposite directions to rotate synchronously, thereby driving the two nuts 18 on it to move relative to each other or in opposite directions. The movement of the two nuts 18 causes the top pipe fixing sleeve 19 and the bottom pipe fixing sleeve 110 to move synchronously, thereby facilitating the initial limiting of both ends of the polyethylene pipe.

[0051] After initial positioning, the power supply to the two second electric push rods 31 is simultaneously turned on to make the two V-shaped plates 32 move relative to each other. The movement of the two V-shaped plates 32 can facilitate the adjustment of the position of the polyethylene pipe. By adjusting its position, the fixed position of the polyethylene pipe is ensured to be exactly at the center of the top pipe fixing sleeve 19 and the bottom pipe fixing sleeve 110, which facilitates better fixation later. After the position is adjusted, the power supply to the first motor 194 is turned on to make the gear ring 197 rotate. The rotation of the gear ring 197 causes the gear 198 meshing with it to rotate synchronously. The rotation of the gear 198 drives the rack 199 meshing with it to move. The movement of the rack 199 causes the inner clamping plate 1910 of the pipe to move, which facilitates the fixation of the inner wall of the polyethylene pipe. The cooperation of the telescopic component 192 and the outer clamping plate 193 of the pipe facilitates the fixation of the inner and outer walls of the polyethylene pipe.

[0052] After fixing, the power supply to the electric telescopic rod 14 is turned on again, causing the electric telescopic rod 14 to extend. The extension of the electric telescopic rod 14 causes the rotating plate 12 to rotate 90 degrees in the opposite direction. After the rotating plate 12 rotates 90 degrees in the opposite direction, the side wall of the rotating plate 12 will press the trigger plate 22. When the trigger plate 22 is pressed, it will contact the trigger switch 23. At this time, the trigger switch 23 will first disconnect the power supply to the electric telescopic rod 14, and then connect the power supply to the second electric push rod 31. By connecting the power supply to the second electric push rod 31, it is easy to release the fixation of the V-shaped plate 32 on the polyethylene pipe. Then, the tilt angle of the polyethylene pipe can be adjusted according to the user's needs. Adjusting its tilt angle facilitates the user's subsequent installation, thereby conveniently meeting the different needs of the user.
