Description

Technical Field

[0001] The present invention relates to the technical field of the production of glass fiber reinforced plastic sand-filled pipes, and more specifically, to a pipe body alignment device for the production of glass fiber reinforced plastic sand-filled pipes. Background Art

[0002] The glass fiber reinforced plastic sand-filled pipe is a new type of composite material made of resin as the matrix material, glass fiber and its products as the reinforcing material, and quartz sand as the filling material. With its excellent corrosion resistance, hydraulic characteristics, light weight and high strength, large conveying flow rate, convenient installation, short construction period and low comprehensive investment, it has become the best choice for the chemical industry, drainage projects and pipeline projects, and is used in various municipal sewage treatments, water supply and tap water transportation, farmland irrigation, petrochemical industry. The glass fiber reinforced plastic sand-filled pipe adopts a socket connection method, which is convenient for installation and connection. A double O-ring is used at the joint to adapt to thermal expansion and contraction.

[0003] During the transportation process after the production of the glass fiber reinforced plastic sand-filled pipe, because the pipe body of the glass fiber reinforced plastic sand-filled pipe is large and cylindrical, the glass fiber reinforced plastic sand-filled pipe will shift during the transportation process, and an alignment device is required to move and align the glass fiber reinforced plastic sand-filled pipe. During the production and transportation of glass fiber reinforced plastic sand-filled pipes of different sizes, it is necessary to adjust separately according to the size of the pipe body to maintain the stability of the alignment device.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0005] The purpose of the present invention is to provide a pipe body alignment device for the production of glass fiber reinforced plastic sand-filled pipes to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A pipe body alignment device for the production of glass fiber reinforced plastic sand-filled pipes includes a pipe body and a base. It is characterized in that a first groove is opened at the upper end of the base, and a first transmission mechanism, a second transmission mechanism and an alignment mechanism are arranged in the first groove. The first transmission mechanism is arranged at the lower end of the first groove, the lower ends of both sides of the inner wall of the first groove are provided with inclined surfaces and the second transmission mechanism is arranged, and the alignment mechanisms are arranged on both inner walls of the first groove.

[0008] Further, the first transmission mechanism includes a first transmission roller, a first limiting plate and a trigger assembly. Both ends of the first transmission roller are rotatably connected to the first limiting plate through a rotating shaft. A first sliding groove is opened on the lower inner wall of the first groove and the first limiting plate is slidably sleeved thereon. A connecting plate is fixedly connected to the lower ends of both first limiting plates, and the trigger assembly is arranged on one side of the first sliding groove.

[0009] Further, circular grooves I are formed at the lower ends of the first limiting plates. Guide rods are slidably sleeved in the circular grooves I. The lower ends of the guide rods are fixedly connected to the inner walls of the first chutes, and a first spring is fixedly connected between the upper ends of the guide rods and the circular grooves I.

[0010] Further, the triggering assembly includes a pressing block, an electricity-connecting post and a conductive sheet. A second groove is formed inside the first chute. The pressing block is rotatably connected to the second groove through a rotating shaft. The conductive sheet is embedded at the lower end of the pressing block. An electricity-connecting post matched with the conductive sheet is fixedly connected in the second groove. A elastic sheet is fixedly connected between the pressing block and the second groove.

[0011] Further, the second transmission mechanism includes a second transmission roller and second limiting plates. Two second limiting plates are fixedly connected to the inclined surfaces on both sides of the first transmission roller. The second transmission roller is rotatably connected between the two second limiting plates through a rotating shaft.

[0012] Further, the deviation rectifying mechanism includes a third transmission roller, third limiting plates, a motor and a torsion assembly. Motors are embedded on both sides of the housing. The outer shafts of the motors are fixedly connected with first gears. A torsion assembly is meshed with one side of each first gear. One end of each torsion assembly is fixedly connected with a third limiting plate. The third transmission roller is rotatably connected to the inner sides of the third limiting plates through a rotating shaft. The two third transmission rollers are arranged in the first groove.

[0013] Further, the torsion assembly includes a second gear, a shaft sleeve and a spiral rod. Second chutes are formed on both sides of the housing. The spiral rods are slidably sleeved in the second chutes and are fixedly connected with the third limiting plates. The outer wall of the spiral rod is threadedly connected with the shaft sleeve. The outer wall of the shaft sleeve is rotatably sleeved with the second gear and is meshed with the first gear. A plurality of circular grooves II are formed in the inner wall of the second gear. Balls are slidably arranged in the circular grooves II. Second springs are arranged between the balls and the circular grooves II. A clamping groove matched with the balls is formed on the outer wall of the shaft sleeve.

[0014] Further, two ends of one side of the third limiting plate far away from the third transmission roller are fixedly connected with slide rails. The slide rails penetrate through the housing and are slidably connected with the housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] , through the first transmission mechanism set, when the glass fiber reinforced plastic sand-filled pipe is being transported, the gravity of the glass fiber reinforced plastic sand-filled pipe squeezes the drive roller one downward, activating the trigger component, enabling the deviation rectification mechanism to rectify the pipe body. Through the second transmission mechanism set on both inclined surfaces, the drive roller two can support the pipe body and assist the pipe body in moving. Through the deviation rectification mechanism set, while rectifying the pipe body, it can also assist the pipe body in moving, making the pipe body more stable during production movement. And a torsion component is set in the deviation rectification mechanism, which can prevent the deviation rectification mechanism from driving the drive roller three to excessively squeeze the pipe body, resulting in the pipe body being oppressed and broken. And through the cooperation of the first transmission mechanism and the deviation rectification mechanism, it can automatically rectify glass fiber reinforced plastic sand-filled pipes of different sizes without additional manual adjustment.

[0017] , the drive roller one set supports the pipe body and assists the sliding of the pipe body. When the pipe body presses the drive roller one downward, the connecting plate connected to the limit plate one moves downward together with the limit plate one, thereby squeezing the trigger component to make the motor in the deviation rectification mechanism operate to push the drive roller three to continuously move, pushing the pipe body to rectify the pipe body. And the set connecting plate can also stabilize the movement of the limit plate one, making the sliding of the limit plate one smoother. Through the set guide rod, the sliding stability of the limit plate one can be further improved. And the spring one set between the guide rod and the limit plate one can lift the limit plate one when the pipe body on the drive roller one moves away, causing the connecting plate to stop squeezing the trigger component, thereby resetting the deviation rectification mechanism. Through the conductive sheet in the set extrusion block, when the connecting plate presses the extrusion block, the conductive sheet contacts the power connection post, thereby activating the deviation rectification mechanism to rectify the pipe body. And the set elastic sheet will push the extrusion block to reset when the connecting plate separates from the extrusion block, thereby separating the conductive sheet from the power connection post and resetting the deviation rectification mechanism.

[0018] , the drive roller two set can support the pipe body and assist the pipe body in moving. By setting the drive roller two on the inclined surfaces on both sides, while the drive roller two supports the pipe body, the pipe body can also contact the first transmission mechanism to activate the deviation rectification mechanism to rectify the movement of the pipe body. Through the operation of the set motor, the gear one drives the torsion component to operate to push the drive roller three to move, making the drive roller three contact and squeeze the pipe body. And the set torsion component will disconnect the transmission of the gear one when the pipe body is squeezed and cannot move, avoiding excessive pressure exerted by the drive roller three on the pipe body, resulting in the pipe body being broken.

[0019] , by setting the second gear to mesh with the first gear, when the motor runs, the first gear can drive the second gear to rotate. And the ball bearings arranged in the second gear are under the pressure of the second spring and are engaged with the card slots of the shaft sleeve, so that when the second gear rotates, it will drive the shaft sleeve to rotate, thereby enabling the screw rod to push the third transmission roller to contact the pipe body. When the third transmission roller corrects the deviation of the pipe body and cannot continue to push the pipe body, the ball bearings slide into the second round groove due to the torsion of the second gear, disconnecting the connection between the second gear and the shaft sleeve, thus avoiding the third transmission roller continuously squeezing the pipe body and causing the pipe body to break. The set slide rail can play a stabilizing role when the third transmission roller moves, making the movement of the third transmission roller smoother, and can also prevent the screw rod from rotating together with the shaft sleeve, resulting in the deviation correction mechanism being unable to operate normally.

The first transmission mechanism 4 is arranged at the lower end of the first groove 3. By setting the first transmission mechanism 4, when the fiberglass sand-filled pipe is being transported, the first transmission roller 7 is pushed down by the gravity of the fiberglass sand-filled pipe, activating the trigger assembly 9, so that the deviation rectification mechanism 6 rectifies the pipe body 1.

The deviation rectification mechanisms 6 are arranged on both inner walls of the first groove 3. By arranging the deviation rectification mechanisms 6, while rectifying the pipe body 1, it can also assist the movement of the pipe body 1, making the pipe body 1 more stable during production movement. And a torque assembly 25 is arranged in the deviation rectification mechanism 6, which can prevent the deviation rectification mechanism 6 from driving the third transmission roller 22 to excessively squeeze the pipe body 1, resulting in the pipe body 1 being crushed due to compression.

[0032] Through the above solution of the present invention, with the first transmission mechanism 4 provided, when the glass fiber reinforced plastic sand-filled pipe is being transported, the gravity of the glass fiber reinforced plastic sand-filled pipe squeezes the first driving roller 7 downward, activating the trigger assembly 9, causing the deviation rectifying mechanism 6 to rectify the pipe body 1.

The lower inner wall of the first groove 3 is provided with a first sliding groove 10 and slidably sleeved with the first limiting plate 8. The lower ends of the two first limiting plates 8 are fixedly connected with a connecting plate 11. A triggering component 9 is arranged on one side of the first sliding groove 10. By arranging the first transmission roller 7 to support the pipe body 1 and assist the sliding of the pipe body 1, when the pipe body 1 presses the first transmission roller 7 to move downward, the connecting plate 11 connected to the first limiting plate 8 moves downward together with the first limiting plate 8, thereby squeezing the triggering component 9 to make the motor 24 in the rectifying mechanism 6 operate to push the third transmission roller 22 to continuously move, pushing the pipe body 1 to rectify the pipe body 1. The arranged connecting plate 11 can also stabilize the movement of the first limiting plate 8, making the sliding of the first limiting plate 8 smoother. Circular grooves 12 are respectively opened at the lower ends of the first limiting plates 8. Guide rods 13 are respectively slidably sleeved in the circular grooves 12.

The first spring 14 arranged between the guide rods 13 and the first limiting plates 8 can lift the first limiting plate 8 when the pipe body 1 on the first transmission roller 7 is removed, so that the connecting plate 11 stops squeezing the triggering component 9, thereby resetting the rectifying mechanism 6.

[0034] Through the above solution of the present invention, the first driving roller 7 is provided to support the pipe body 1 and assist the sliding of the pipe body 1. When the pipe body 1 presses the first driving roller 7 downward, the connecting plate 11 connected to the first limiting plate 8 moves downward together with the first limiting plate 8, thereby squeezing the trigger assembly 9 to make the motor 24 in the deviation rectifying mechanism 6 operate to push the third driving roller 22 to continuously move, pushing the pipe body 1 to rectify the deviation of the pipe body 1. The provided connecting plate 11 can also stabilize the movement of the first limiting plate 8, making the sliding of the first limiting plate 8 smoother.

When the connecting plate 11 presses the extrusion block 15 through the conductive sheet 17 in the extrusion block 15, the conductive sheet 17 contacts the electrical connection post 16, thereby activating the deviation rectifying mechanism 6 to rectify the deviation of the pipe body 1. The provided elastic sheet 19 will push the extrusion block 15 to reset when the connecting plate 11 is separated from the extrusion block 15, thereby separating the conductive sheet 17 from the electrical connection post 16 and resetting the deviation rectifying mechanism 6.
