Description

Technical Field

[0001] This invention relates to a conveying device for kraft tube base pipe and a method for producing kraft tubes, belonging to the field of kraft tube production technology. Background Technology

[0002] Krah pipe (full name: hot-wound high-density polyethylene spiral wound structured wall pipe) is a pipe material made primarily of high-density polyethylene resin (HDPE) through a hot-wound process. It is mainly used for urban water supply, drainage, long-distance water transmission, and farmland irrigation.

[0003] Current production technology for Krah pipes is not comprehensive and has the following drawbacks: 1. During continuous processing, the movement of the Krah pipe base is done manually, resulting in high labor intensity and poor continuity of the production process, which also limits the production efficiency of the pipes. 2. The lack of adjustable buffer supports on the left and right sides prevents the leveling and buffering functions of the conveyor rollers from being realized.

[0004] To solve one of the above problems, there is an urgent need for a conveying device for kraft tube base pipes and a method for producing kraft tubes. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to realize the efficient conveying of the Krah tube base pipe by using a conveying roller as the driving force, which drives the Krah tube base pipe on it to be conveyed, so as to facilitate subsequent processing, and the mechanized conveying method eliminates the need for manual handling and reduces the workload of workers. To this end, a conveying device for Krah tube base pipe and a production method for Krah tube are provided.

[0006] The conveying device for the kraft tube base of the present invention includes a base frame supported on the ground, on which a vertical column is vertically connected. The device is characterized by further including a conveying roller. A left adjustable buffer bracket is installed on one side of the vertical column, and a right adjustable buffer bracket, symmetrical to the left adjustable buffer bracket, is installed on the other side of the vertical column. A left hinge seat is installed at the actuating end of the left adjustable buffer bracket, and a right hinge seat is installed at the actuating end of the right adjustable buffer bracket. A left connecting screw is installed on the left hinge seat, and a right connecting insert shaft is installed on the right hinge seat. One end of the conveying roller is provided with an internally threaded tube that is threadedly connected to the left connecting screw, and the other end of the conveying roller is provided with a sliding sleeve B that is inserted and connected to the right connecting insert shaft.

[0007] Using a conveyor roller as the driving force, the conveyor roller drives the Krah tube base pipe to be transported, realizing the efficient transportation of the Krah tube base pipe, facilitating subsequent processing. The mechanized transportation method eliminates the need for manual handling, reducing the workload of workers. In addition, by adding adjustable buffer supports on the left and right sides, the conveyor roller can be leveled and buffered.

[0008] Preferably, in any of the above embodiments, the base frame is a U-shaped structure, including a rectangular frame, within which a base frame beam is provided, and a vertical column is vertically connected to the middle of the base frame. The base frame provides effective support for the vertical column.

[0009] In any of the above embodiments, preferably, the conveying roller includes a horizontal drum with an internal external rotor motor. The external rotor motor includes an external rotor and a motor shaft located at the center of the external rotor. The external rotor and the horizontal drum are coaxially arranged and connected as a single unit. The motor shaft has two connecting ends, respectively connected to one end of a left horizontal support rod and one end of a right horizontal support rod. One end of the left horizontal support rod is coaxially arranged and welded to an internally threaded pipe, and the other end is coaxially arranged and welded to a sliding sleeve B. Using an external rotor motor as the driving force to drive the horizontal drum to rotate, the horizontal drum drives the Krah tube base pipe on it for conveying, thus achieving effective conveying of the Krah tube base pipe.

[0010] In any of the above embodiments, it is preferred that the top of the vertical column is vertically connected to a strip-shaped top plate, the left connecting screw is threaded with a locking nut, and one end of the internally threaded tube is abutted against the locking nut.

[0011] In any of the above embodiments, preferably, the left adjustable buffer bracket includes a left bottom limiting plate fixed to one side of the vertical column. A first screw parallel to the vertical column and a left damper are provided between the left bottom limiting plate and the strip top plate. The first screw passes through the horizontal support beam A. One end of the horizontal support beam A is fixedly connected to the left damper through a left fixing seat. The other end of the horizontal support beam A is vertically installed with a vertical support beam A. A left hinge seat is installed at the top of the vertical support beam A. An upper pressure plate A and a lower support plate A are respectively sleeved on the first screws on the upper and lower sides of the horizontal support beam A. An elastic component A is sleeved on the first screw between the upper pressure plate A and the horizontal support beam A. An elastic component B is sleeved on the first screw between the horizontal support beam A and the lower support plate A. The upper section of the first screw is threadedly connected to an upper connecting nut A that abuts against the upper surface of the upper pressure plate A. The lower section of the first screw is threadedly connected to a lower connecting nut A that abuts against the lower surface of the lower support plate A.

[0012] By adjusting the positions of the upper connecting nut A and the lower connecting nut A on the first screw, the height of the horizontal support beam A can be adjusted. If the upper connecting nut A and the lower connecting nut A are adjusted downward relative to the first screw at the same time, the horizontal support beam A will also be adjusted downward relative to the first screw, thereby reducing the overall height of the horizontal support beam A. The height of the conveyor roller is also reduced. When the conveyor roller is in a horizontal state, the left adjustable buffer bracket and the right adjustable buffer bracket need to be adjusted simultaneously. After adjustment, the conveyor roller is still in a horizontal state.

[0013] When the conveyor roller is not horizontal, only the height of the adjustable buffer bracket on the right side can be adjusted. The sliding sleeve B is connected to the connecting shaft on the right side by a plug-in method, which has adjustment space and realizes the horizontal adjustment of the conveyor roller.

[0014] In any of the above embodiments, preferably, the left damper includes a cylinder A, with an upper end cover A and a lower end cover A respectively sealing both ends of the cylinder A. A piston A is disposed inside the cylinder A, with an upper piston rod A and a lower piston rod A respectively connected to both end faces of the piston A.

Hydraulic oil is injected into the cylinder A, and the left fixed seat is fixed to the outer wall of the cylinder A.

[0015] The elastic components A and B, together with the left-side damper, buffer the conveying roller, mitigating the impact force of the Krah tube base on the conveying roller and protecting it. Specifically, during the conveying of the Krah tube base, the conveying roller is impacted by the Krah tube base. The horizontal support beam A compresses the elastic component B downwards, and the left-side fixed seat drives the cylinder A downwards. The cylinder A and piston A move relative to each other, and the hydraulic oil in the lower cavity flows into the upper cavity through the connecting hole A, achieving a buffering and shock absorption effect. The impact force disappears, and the elastic component B can drive the horizontal support beam A back to its balanced state.

[0016] In any of the above embodiments, preferably, the right-side adjustable buffer bracket includes a right-side bottom limiting plate fixed to one side of the vertical column. A second screw parallel to the vertical column and a right-side damper are provided between the right-side bottom limiting plate and the lower connecting nut A. The second screw passes through the horizontal support beam B. One end of the horizontal support beam B is fixedly connected to the right-side damper through a right-side connecting seat. The other end of the horizontal support beam B is vertically mounted with a vertical support beam B. A right-side hinge seat is installed at the top of the vertical support beam B. An upper pressure plate B and a lower support plate B are respectively sleeved on the second screws on the upper and lower sides of the horizontal support beam B. An elastic component C is sleeved on the second screw between the upper pressure plate B and the horizontal support beam B. An elastic component D is sleeved on the second screw between the horizontal support beam B and the lower support plate B. The upper section of the second screw is threadedly connected to an upper connecting nut B that abuts against the upper surface of the upper pressure plate B. The lower section of the second screw is threadedly connected to a lower connecting nut B that abuts against the lower surface of the lower support plate B.

[0017] In any of the above embodiments, preferably, the right-side damper includes a cylinder B, with an upper end cover B and a lower end cover B respectively sealing both ends of the cylinder B. A piston B is disposed inside the cylinder B, with an upper piston rod B and a lower piston rod B respectively connected to both end faces of the piston B. The upper end of the upper piston rod B passes through the upper end cover B and is fixedly connected to the strip-shaped top plate, and the bottom end of the lower piston rod B passes through the lower end cover B and is fixedly connected to the right-side bottom limiting plate. The piston B divides the inner cavity of the cylinder B into an upper cavity and a lower cavity. A connecting hole B is opened on the piston B to connect the upper cavity and the lower cavity. Hydraulic oil is injected into the cylinder B, and the right-side connecting seat 30 is fixed to the outer wall of the cylinder B.

[0018] In any of the above embodiments, it is preferred that the elastic components A, B, C, and D are all compression springs, and the right-side connecting shaft is a spline shaft.

[0019] The method for producing Krah tube base pipe according to the present invention is characterized in that multiple sets of conveying devices for Krah tube base pipe are arranged sequentially at intervals, and conveying rollers are used as driving force to drive the Krah tube base pipes on them for conveying, thereby realizing the effective conveying of Krah tube base pipes and facilitating subsequent processing.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The conveying device for Krah tube base pipes described in this invention uses a conveying roller as the driving force. The conveying roller drives the Krah tube base pipes on it to be conveyed, realizing the effective conveying of Krah tube base pipes, which facilitates subsequent processing. The mechanized conveying method eliminates the need for manual handling and reduces the workload of workers.

[0021] The conveying device for the Krah tube base pipe described in this invention achieves the functions of leveling and buffering the conveying rollers by adding an adjustable buffer bracket on the left and an adjustable buffer bracket on the right.

[0022] The conveying device for the Krah tube base pipe of the present invention allows for adjustment of the height of the adjustable buffer bracket on the right side only when the conveying roller is not horizontal. The sliding sleeve B is connected to the right connecting shaft by a plug-in method, providing adjustment space and enabling horizontal adjustment of the conveying roller.

[0023] The method for producing Krah tube base pipes according to the present invention arranges multiple sets of the above-mentioned Krah tube base pipe conveying devices in sequence at intervals, and uses conveying rollers as driving force. The conveying rollers drive the Krah tube base pipes on them to be conveyed, thereby realizing the effective conveying of Krah tube base pipes and facilitating subsequent processing.

[0026] The present invention will be further described below with reference to the accompanying drawings. The present invention will be further illustrated by specific embodiments, but it is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0027] Example 1, as Figure 1 As shown, the conveying device for a kraft tube base includes a base frame 1 supported on the ground. A vertical column 2 is vertically connected to the base frame 1. The device also includes a conveying roller 9. A left adjustable buffer bracket 3 is installed on one side of the vertical column 2, and a right adjustable buffer bracket 4, symmetrical to the left adjustable buffer bracket 3, is installed on the other side of the vertical column 2. A left hinge seat 5 is installed at the end of the left adjustable buffer bracket 3, and a right hinge seat 6 is installed at the end of the right adjustable buffer bracket 4. A left connecting screw 10 is installed on the left hinge seat 5, and a right connecting insert shaft 11 is installed on the right hinge seat 6. One end of the conveying roller 9 is provided with an internally threaded tube 7 that is threadedly connected to the left connecting screw 10, and the other end of the conveying roller 9 is provided with a sliding sleeve B8 that is inserted and connected to the right connecting insert shaft 11.

[0028] Using the conveying roller 9 as the driving force, the conveying roller 9 drives the corrugated pipe base pipe thereon to be conveyed, achieving the effective conveyance of the corrugated pipe base pipe, facilitating subsequent processing. The mechanized conveying method eliminates manual handling and reduces the labor intensity of workers. In addition, by installing the left adjustable buffer bracket 3 and the right adjustable buffer bracket 4, the functions of leveling and buffering of the conveying roller 9 are realized.

[0029] Embodiment 2, as Figure 1-2 shown, the conveying device for the corrugated pipe base pipe includes a chassis 1 supported on the ground. A vertical column 2 is vertically connected to the chassis 1. It further includes a conveying roller 9. A left adjustable buffer bracket 3 is installed on one side of the vertical column 2, and a right adjustable buffer bracket 4 symmetrical to the left adjustable buffer bracket 3 is installed on the other side of the vertical column 2. A left hinge seat 5 is installed at the execution end of the left adjustable buffer bracket 3, and a right hinge seat 6 is installed at the execution end of the right adjustable buffer bracket 4. A left connecting screw 10 is installed on the left hinge seat 5, and a right connecting socket 11 is installed on the right hinge seat 6. An internal thread tube 7 threadedly connected to the left connecting screw 10 is provided at one end of the conveying roller 9, and a sliding sleeve B8 inserted and connected to the right connecting socket 11 is provided at the other end of the conveying roller 9.

[0030] Further, referring to Figure 2 , the chassis 1 is in a "day" - shaped structure, including a rectangular frame 1.1. A chassis beam 1.2 is arranged inside the rectangular frame 1.1, and a vertical column 2 is vertically connected to the middle of the chassis beam 1.2. The chassis 1 provides effective support for the vertical column 2.

[0031] Further, referring to Figure 3 , the conveying roller 9 includes a horizontal drum 9.1. An external rotor motor 9.2 is built in the horizontal drum 9.1. The external rotor motor 9.2 includes an external rotor and a motor shaft arranged at the center of the external rotor. The external rotor is coaxially arranged with the horizontal drum 9.1 and connected as a whole. The motor shaft has two connection ends, which are respectively connected to one ends of a left - hand horizontal support rod 9.3 and a right - hand horizontal support rod 9.4. One end of the left - hand horizontal support rod 9.3 is coaxially arranged with the internal thread tube 7 and is welded. One end of the 9.4 is coaxially arranged with the sliding sleeve B8 and is welded. Using the external rotor motor 9.2 as the driving force to drive the horizontal drum 9.1 to rotate, the horizontal drum 9.1 drives the corrugated pipe base pipe thereon to be conveyed, achieving the effective conveyance of the corrugated pipe base pipe.

[0032] Further, a strip - shaped top plate 12 is vertically connected to the top of the vertical column 2. A locking nut 44 is threadedly connected to the left connecting screw 10, and one end of the internal thread tube 7 abuts against the locking nut 44.

[0033] Furthermore, referring to Figure 4 The left adjustable buffer bracket 3 includes a left bottom limiting plate 13 fixed to one side of the vertical column 2. A first screw 15 parallel to the vertical column 2 and a left damper 14 are provided between the left bottom limiting plate 13 and the strip top plate 12. The first screw 15 passes through the horizontal support beam A16. One end of the horizontal support beam A16 is fixedly connected to the left damper 14 via a left fixing seat 18. A vertical support beam A17 is vertically installed at the other end of the horizontal support beam A16. A left hinge seat 5 is installed at the top of the vertical support beam A17. An upper pressure plate A21 and a lower support plate A22 are respectively fitted on the first screw 15 on the upper and lower sides of the horizontal support beam A16. An elastic component A19 is fitted on the first screw 15 between the upper pressure plate A21 and the horizontal support beam A16. An elastic component B20 is fitted on the first screw 15 between the horizontal support beam A16 and the lower support plate A22. The upper section of the first screw 15 is threadedly connected to an upper connecting nut A23 that abuts against the upper surface of the upper pressure plate A21. The lower section of the first screw 15 is threadedly connected to a lower connecting nut A24 that abuts against the lower surface of the lower support plate A22.

[0034] By adjusting the positions of the upper connecting nut A23 and the lower connecting nut A24 on the first screw 15, the height of the horizontal support beam A16 can be adjusted. If the upper connecting nut A23 and the lower connecting nut A24 are simultaneously adjusted downward relative to the first screw 15, the horizontal support beam A16 will also be adjusted downward relative to the first screw 15, thereby reducing the overall height of the horizontal support beam A16. The height of the conveyor roller 9 is also reduced. When the conveyor roller 9 is in a horizontal state, the left adjustable buffer bracket 3 and the right adjustable buffer bracket 4 need to be adjusted simultaneously. After adjustment, the conveyor roller 9 is still in a horizontal state.

[0035] When the conveyor roller 9 is not horizontal, only the height of the right adjustable buffer bracket 4 can be adjusted. The sliding sleeve B8 is connected to the right connecting shaft 11 by a plug-in method, which has adjustment space and realizes the horizontal adjustment of the conveyor roller 9.

[0036] Furthermore, referring to Figure 5The left damper 14 includes a cylinder A37, with an upper end cover A39 and a lower end cover A40 sealing both ends of the cylinder A37.

The piston A38 divides the inner cavity of the cylinder A37 into an upper cavity and a lower cavity. A connecting hole A41 connecting the upper cavity and the lower cavity is opened on the piston A38. Hydraulic oil is injected into the cylinder A37. The left fixed seat 18 is fixed on the outer wall of the cylinder A37.

[0037] The elastic components A19 and B20, together with the left-side damper 14, can buffer the conveying roller 9, reducing the impact force of the Krah tube base pipe on the conveying roller 9 and protecting it. Specifically, during the conveying process of the Krah tube base pipe, the conveying roller 9 is impacted by the Krah tube base pipe. The horizontal support beam A16 compresses the elastic component B20 downward, and the left-side fixed seat 18 drives the cylinder A37 downward. The cylinder A37 and the piston A38 move relative to each other. The hydraulic oil in the lower cavity flows into the upper cavity through the connecting hole A41, achieving the effect of buffering and shock absorption. The impact force disappears, and the elastic component B20 can drive the horizontal support beam A16 back to a balanced state.

[0038] Furthermore, referring to Figure 6 The right-side adjustable buffer bracket 4 includes a right-side bottom limiting plate 25 fixed to one side of the vertical column 2. A second screw 27 parallel to the vertical column 2 and a right-side damper 26 are provided between the right-side bottom limiting plate 25 and the lower connecting nut A24.

An elastic component C31 is fitted on the second screw 27 between the upper pressure plate B33 and the horizontal support beam B28, and an elastic component D32 is fitted on the second screw 27 between the horizontal support beam B28 and the lower support plate B34.

[0039] Furthermore, referring to Figure 7The right-side damper 26 includes a cylinder B, with an upper end cover B and a lower end cover B sealing both ends of the cylinder B. A piston B is disposed inside the cylinder B, with an upper piston rod B and a lower piston rod B connected to both ends of the piston B. The upper end of the upper piston rod B passes through the upper end cover B and is fixedly connected to the strip-shaped top plate 12, while the bottom end of the lower piston rod B passes through the lower end cover B and is fixedly connected to the right-side bottom limiting plate 25.

[0044] The conveying device for the Krah tube base pipe of the present invention allows for adjustment of the height of the adjustable buffer bracket on the right side only when the conveying roller is not horizontal.
