A double-track pipeline production and transfer truss

Abstract

The present invention relates to a dual-track pipeline production and transfer truss, comprising a mounting frame, a transfer mechanism mounted on the mounting frame, and clamping mechanisms uniformly disposed on the transfer mechanism. The present invention addresses current issues with pipeline production and transfer, such as a simple truss motion path requiring multiple reciprocating motions along the same path to complete the production of a single pipeline, resulting in a large truss motion stroke and low transfer efficiency. Furthermore, the truss motion stroke currently used in pipeline production operations is a reciprocating structure, making it incapable of cyclically transferring pipeline molds, i.e., unable to coordinate with pipeline processing equipment to achieve continuous production.

Description

Technical Field

[0001] The present application relates to the technical field of pipeline transportation, and in particular to a double-track pipeline production and transportation truss. Background Art

[0002] Carat tube is a common type of pipe with good flexibility and easy installation. It is not only corrosion-resistant and aging-resistant, but also recyclable and is a green and environmentally friendly product. During the production process of carat tube, the material is spirally wound around the mold, and then the mold is cooled to allow the pipe to be quickly formed.

[0027] The following is combined with Figure 1-7 This application is described in further detail.

[0028] An embodiment of the present application discloses a double-track pipeline production and transfer truss, which can perform cyclic operations during pipeline production operations, reduce the movement stroke of the truss during pipeline operations, and improve the stability of the truss transfer pipeline mold, thereby improving the efficiency of pipeline production.

The clamping mechanism 3 clamps the processed pipe fittings during movement, and cooperates with the transfer mechanism 2 to drive the pipe fittings to move in position. Moreover, in this process, the transfer mechanism 2 and the clamping mechanism 3 cooperate in operation, and compared with the traditional running truss, it can complete the continuous pipeline production and transfer operation without the need for reciprocating movement of the truss, saving time and cost, and improving the efficiency of pipeline production.

[0031] The driving branch chain 7 includes a dual-axis motor 71 mounted on the outer wall of the mounting frame 1 through a motor seat, and a rotating column 72 is symmetrically mounted on the output shaft of the dual-axis motor 71. The rotating column 72 is mounted on a fixed seat through a bearing, and the fixed seat is set on the mounting frame 1. A second gear 73 is provided on the rotating column 72, and a third gear 74 is engaged with the second gear 73. The third gear 74 is fixed on the rotating rod 75, and the rotating rod 75 is fixed on the side wall of the mounting frame 1 through a bearing. A driving sprocket 76 is installed on the rotating rod 75, and a driving chain 77 is connected between the driving sprocket 76 and the rotating branch chain 4.

[0032] By adopting the above technical solution, the dual-axis motor 71 is started during operation to control the rotation of the rotating column 72. During the rotation process, the rotating column 72 drives the second gear 73 to rotate synchronously. The second gear 73 cooperates with the third gear 74 during operation to control the synchronous rotation of the rotating rod 75. The rotating rod 75 controls the rotating branch chain 4 to start working through the cooperation between the driving sprocket 76 and the driving chain 77. The cooperation between the rotating branch chain 4 and the clamping mechanism 3 drives the pipe fittings in production to move in different processing steps.

[0033] The rotating branch chain 4 includes a rotating column 41 symmetrically arranged on the mounting frame 1 through a bearing, a rotating sprocket 42 is installed on the outer wall of the rotating column 41, and the two rotating sprockets 42 are connected by a rotating chain 43. A driven sprocket 44 cooperating with the driving chain 77 is installed on the rotating column 41, and a movable mounting frame 45 is connected to the rotating chain 43. A limiting sliding plate 46 is installed on the inner wall of the mounting frame 1, and the movable mounting frame 45 is slidably connected to the limiting sliding plate 46. A mounting hole is opened on the movable mounting frame 45, and a mounting sleeve 47 is fixed in the mounting hole.

[0034] By adopting the above technical solution, in specific operations, the driving sprocket 76, the driving chain 77 and the driven sprocket 44 cooperate with each other to drive the rotating column 41 to rotate. During the rotation, the rotating column 41 drives the rotating chain 43 to perform cyclic rotation adjustment through cooperation with the rotating sprocket 42. During the movement, the rotating chain 43 synchronously drives the mobile mounting frame 45 to move along the limiting sliding plate 46. The limiting sliding plate 46 plays a role in guiding and assisting the mobile mounting frame 45 to move stably during the movement of the mobile mounting frame 45.

[0035] The mounting branch chain 5 includes a mounting actuator tube 51 arranged between two mounting sleeves 47 through bearings, locking assemblies 52 are symmetrically arranged at both ends of the mounting actuator tube 51, an auxiliary groove is opened on the lower end surface of the mounting actuator tube 51, a rotating motor 53 is installed on the inner wall of the mounting actuator tube 51 through a motor seat, the output shaft of the rotating motor 53 is connected to the winding tube 54 through a coupling, the winding tube 54 is installed on the support through a bearing, and the support is fixed on the inner wall of the mounting actuator tube 51, a winding sprocket 55 is symmetrically arranged on the winding tube 54, a control chain 56 is installed on the winding sprocket 55, the lower end of the control chain 56 is connected to the clamping mechanism 3, and a limiting assembly 57 is provided on the winding tube 54.

[0036] By adopting the above technical solution, in specific operations, after the installation sleeve 47 follows the mobile installation frame 45 to move to the specified process position, the rotating motor 53 is started to control the winding tube 54 to rotate. The winding tube 54 drives the winding sprocket 55 to rotate during the rotation adjustment process. During the rotation process, the winding sprocket 55 drives the clamping mechanism 3 to adjust the height through the control chain 56, so that the clamping mechanism 3 moves to a position where it can clamp the pipe mold. At the same time, the installation execution tube 51 and the installation sleeve 47 are locked by the locking assembly 52 to ensure the stability of the installation execution tube 51 during operation. In order to facilitate the stability of the pipe mold clamping operation, the limit assembly 57 starts to work to limit the winding sprocket 55.

[0037] The locking assembly 52 includes a through groove provided on the installation actuator tube 51, a through rod 521 is slidably arranged in the through groove, the lower end of the through rod 521 is connected to the clamping mechanism 3, locking holes are evenly provided along the circumference of the installation actuator tube 51, and fixing holes that cooperate with the locking holes are evenly provided on the installation sleeve 47. A locking rod 522 is slidably provided in the locking hole, a spring is provided between the locking rod 522 and the inner wall of the installation actuator tube 51, and a driving rod 523 is slidably provided in the installation sleeve 47.

[0038] By adopting the above technical solution in specific operations, when the clamping mechanism 3 moves downward, it simultaneously drives the through rod 521 to move and adjust. During the movement, the through rod 521 drives the abutment block 525 to squeeze the driving rod 523. After being squeezed, the driving rod 523 simultaneously drives the limiting push block 524 to squeeze the locking rod 522. After being squeezed, the locking rod 522 passes through the locking hole and is inserted into the fixing hole, so that the installation execution tube 51 and the installation sleeve 47 are fixed and locked.

[0039] The limiting assembly 57 includes a limiting slide groove opened on the winding tube 54, a two-way cylinder 571 is installed inside the winding tube 54, and a limiting plug rod 572 is symmetrically arranged on the two-way cylinder 571. The winding sprocket 55 is evenly provided with through holes, and the through rod 521 is evenly provided with connecting holes that cooperate with the limiting plug rod 572.

[0040] The locking rod 522 abuts against the outer wall of the driving rod 523 , which is provided with a limit push block 524 . The driving rod 523 abuts against the outer wall of the through rod 521 , which is provided with a abutting block 525 .

[0041] By adopting the above technical solution, when the clamping mechanism 3 is adjusted to a suitable position, the bidirectional cylinder 571 is started to control the limiting rod 572 to move into the insertion hole. In this state, the position of the winding sprocket 55 can be fixed.

[0042] The clamping mechanism 3 includes a supporting mounting frame 31 connected to the mounting support chain 5, the supporting mounting frame 31 is provided with an adjusting support chain 8, the supporting mounting frame 31 is symmetrically provided with an adjusting operation groove, an adjusting execution frame 32 is slidably provided in the adjusting operation groove, the adjusting execution frame 32 is connected to the adjusting support chain 8, an execution clamping frame 33 is installed on the adjustment execution frame 32, a lifting adjustment groove is provided in the middle of the upper end of the execution clamping frame 33, a lifting clamping rod 34 is slidably provided in the lifting adjustment groove, a spring is provided between the lifting clamping rod 34 and the execution clamping frame 33, an arc rubber block is provided at the upper end of the lifting clamping rod 34, a rack 35 is symmetrically provided on the lifting clamping rod 34, an adjusting operation rod 36 is installed on the inner wall of the execution clamping frame 33 through a bearing, the adjusting operation rod 36 is provided with a first gear 38 meshing with the rack 35, an adjusting clamping column 37 is provided on the adjusting operation rod 36, and a rubber ball is installed at the lower end of the adjusting clamping column 37.

[0043] The adjustment branch chain 8 includes a bidirectional motor 81 mounted on the support mounting frame 31 through a motor seat, and a screw 82 is symmetrically arranged on the output shaft of the bidirectional motor 81 through a coupling. The screw 82 is mounted on the base through a bearing, and the base is fixed on the support mounting frame 31. A moving block 83 is provided on the screw 82, and the moving block 83 is slidably set on the inner wall of the support mounting frame 31. The adjustment execution frame 32 is connected to the moving block 83.

[0044] By adopting the above technical solution, during the specific operation process, according to the length of the pipe mold, the bidirectional motor 81 is started to control the screw 82 to rotate. During the rotation process, the screw 82 cooperates with the moving block 83 in a threaded transmission manner to synchronously drive the two adjustment execution frames 32 to move in opposite directions. The execution clamping frame 33 is driven to be inserted into the pipe mold through the two adjustment execution frames 32. First, the bidirectional cylinder 571 is controlled to reset, and then the rotating motor 53 is started to drive the rotating sprocket 42 to rotate. During the rotation operation, the rotating sprocket 42 drives the execution clamping frame 33 to reset from bottom to top through the control chain 56. During the upward movement, the execution clamping frame 33 first makes the arc rubber block at the upper end of the lifting clamping rod 34 rest against the inner wall of the pipe mold, and in the process of continuous upward movement, During the process, the lifting clamping rod 34 is squeezed and begins to move downward. During the downward movement, the lifting clamping rod 34 drives the adjusting working rod 36 to rotate through the mutual cooperation between the rack 35 and the first gear 38. After the rubber ball on the adjusting working rod 36 is pressed against the inner wall of the pipe mold, the execution clamping frame 33 continues to move upward, which drives the pipe to rise synchronously. Lifting the pipe through multi-point contact can disperse the pressure between the pipe and the mold as a whole, reduce the pressure at the contact position, and at the same time improve the stability of the pipe during the lifting and transmission operation. When the position of the pipe is lifted to the qualified height, the two-way cylinder 571 is started, and the two-way cylinder 571 controls the limit rod 572 to pass through the insertion hole and insert into the plug hole to ensure that the height of the pipe lifting can be maintained at all times during work.

[0045] When the pipe is separated from the mold, the mold is driven to circulate through the double-track pipeline production transfer truss, and its movement trajectory moves along with the drive chain 77. When the unloaded mold and the mold wrapped with the pipe are intertwined during movement, the installation execution tube 51 and the installation sleeve 47 that move to the upper position are in an unlocked state. In this state, even if the diameter of the mold changes during operation, resulting in insufficient space when the unloaded mold and the mold wrapped with the pipe are intertwined during movement, the upper and lower clearances of the drive chain 77 can be adjusted without affecting normal operation.

[0046] The following steps are required to transfer the produced pipes using a double-track pipe production transfer truss:

[0047] Step 1: Place the mold, place the mold in the working position of the extruder, and control the mold to rotate during the extruder operation;

[0048] In the second step, the extruder extrude the raw material for making pipe fittings into a strip structure according to the specification requirements, and can move at a constant speed along the length of the die. The extruded material is wound around the die. The die starts to rotate synchronously with the movement of the extruder, so that the extruded material is spirally wound around the die.

[0049] Step 3: Cooling operation. After the winding operation is completed, the clamping mechanism 3 is controlled by the transfer mechanism 2 to move. The clamping mechanism 3 clamps the processed pipe mold during the movement, and cooperates with the transfer mechanism 2 to drive the pipe to the cooling station to cool the wound pipe, so that the pipe can be quickly cooled and shaped.

[0050] Step 4: Demolding operation: After the pipe is cooled, the pipe mold is moved to the demoulding position by the double-track pipeline transfer truss, and the cooled and shaped pipe is removed from the mold;

[0051] Step five is a cyclic operation. After the pipe fitting is taken out from the mold, the pipe fitting mold is moved to the initial position by the double-track pipeline transfer truss designed in the present invention, and multiple molds are prepared so that they can be cyclically operated during the operation.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
