Description

Technical Field

[0001] This invention relates to the field of straight pipe conveying, and in particular to a straight pipe machine mounting device. Background Technology

[0002] In the processing and conveying of straight pipes, the pipes need to be arranged neatly and then conveyed in a unified manner to improve the production efficiency of the entire process.

[0003] The invention disclosed in CN116461950A is a fully automatic straight pipe laying and conveying system, comprising: a base, a pipe-raising device, a tilting device, a conveying device, and a pushing mechanism; wherein, the pipe-raising device and the conveying device are respectively located on both sides of the tilting device on the base; the pushing mechanism is located at one end of the base and is aligned with the conveying wheel on the conveying device. Compared with the prior art, the beneficial effects of this invention are: through innovative design of each structural component, it can achieve rapid transfer and sequential laying of single pipes, and then, through the collective movement, lifting, and switching of multiple pipes, finally complete the parallel conveying of multiple pipes. The entire process adopts a fully automated mechanical design, greatly liberating labor productivity and improving work efficiency.

[0004] The pipes can be directly tilted onto the inclined support. The inclined support pipe conveying surface performs initial gravity natural sorting. During this process, although the straight pipes are arranged in an orderly manner, the position of the pipes in the width direction on the inclined support is uncertain, and the end faces of the straight pipes cannot be guaranteed to be aligned. That is, adjacent straight pipes may be misaligned, and manual handling is still required for adjustment. If no adjustment is made, the straight pipes will also be intertwined when they are flipped to the conveying device. This may result in the transmission pressure roller and linkage roller not being able to contact some straight pipes, causing some pipes to be unable to be conveyed out from one end of the pressure roller conveyor frame, affecting the normal flipping and conveying of the pipes. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a pipe mounting device for a straight pipe machine, which modifies the existing inclined support to align the end faces of the pipes on the inclined support and center the pipes on the inclined support. There is no misalignment between adjacent pipes, and no need to rely on manual handling for adjustment, which facilitates the orderly progress of subsequent pipe flipping, material conveying and other steps.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a straight pipe machine pipe mounting device, including an upper inclined support, an alignment device, an adjustment device and a driving device.

[0007] The inclined support is inclined and a bracket is fixedly installed at its bottom. Feeding rollers are rotatably installed on the inner side of the inclined support, spaced apart along its inclination direction. A box seat is fixedly installed below the inclined support. The alignment device includes symmetrically distributed alignment plates on both sides above the inclined support. The alignment plates move on the inclined support to align the pipe ends and center them above the support. The adjustment device includes a rotating ring. A through groove is opened at the bottom of the box seat, and the rotating ring is rotatably installed within the groove. The adjustment device controls the initial position and stroke of the alignment plates. The driving device is located between the bracket and the box seat. The driving device causes the alignment plates to slide along the box seat and reciprocate.

[0008] As a further description of the above technical solution: the alignment device also includes two sliding plates, which are disposed in the box base and can move along the inner wall of the box base. Each sliding plate and the corresponding alignment plate are fixedly provided with connecting rods that are spaced apart along the length direction of the alignment plate. The connecting rods can pass through two adjacent feeding rollers and do not contact the feeding rollers.

[0009] As a further description of the above technical solution: the alignment device also includes two connecting hooks, which are respectively fixedly disposed on opposite sides of the two sliding plates, and both connecting hooks are bent upwards.

[0010] As a further description of the above technical solution: the adjustment device also includes a rotating plate, which is rotatably disposed on the inner side of the rotating ring. The rotating plate has a strip groove, and an adjustable component is disposed in the strip groove.

[0014] As a further description of the above technical solution: the reciprocating drive assembly includes two symmetrically distributed and rotatably disposed within the base. A first gear disk is fixedly sleeved on the output shaft of the motor. A second gear disk that meshes with the first gear disk is fixedly sleeved on the outer wall of each of the two shafts. A third gear disk is fixedly sleeved at one end of the connecting frame located inside the base. A half-gear disk that meshes with the third gear disk is fixedly sleeved on the outer wall of each of the two shafts.

[0015] As a further description of the above technical solution: the two half-tooth disks are arranged in the same direction and located above the second tooth disk, and the two half-tooth disks alternately mesh with the third tooth disk to make the third tooth disk reciprocate.

[0031] like Figure 1 - Figure 7 As shown in the figure, this embodiment proposes a pipe-mounting device for a straight pipe machine, which includes an upper inclined support, an alignment device, an adjustment device, and a driving device.

[0032] The inclined support 100 is inclined and a bracket 101 is fixedly installed at the bottom.

A box seat 103 is fixedly installed below the inclined support 100. The alignment device 200 includes alignment plates 201 symmetrically distributed and arranged on both sides above the inclined support 100. The alignment plates 201 move on the inclined support 100 to align the end faces of the pipes and center them above the inclined support 100. The adjustment device 300 includes a rotating ring 301.

The adjustment device 300 controls the initial position and stroke of the alignment plate 201. The drive device 400 is located between the bracket 101 and the box seat 103. The drive device 400 causes the alignment plate 201 to slide along the box seat 103 and reciprocate.

[0033] As a preferred embodiment of the present invention, the alignment device 200 includes two sliding plates 202 and two connecting hooks 204. The two sliding plates 202 are disposed in the box base 103 and can move along the inner wall of the box base 103. Each sliding plate 202 and the corresponding alignment plate 201 are fixedly provided with connecting rods 203 that are spaced apart along the length direction of the alignment plate 201. The connecting rods 203 can pass through two adjacent feeding rollers 102 without contacting the feeding rollers 102. The two connecting hooks 204 are respectively fixedly disposed on opposite sides of the two sliding plates 202, and both connecting hooks 204 are bent upward.

[0034] As a preferred technical solution of the present invention, the adjusting device 300 further includes a rotating plate 302 and two push-pull rods 305. The rotating plate 302 is rotatably disposed inside the rotating ring 301. A strip groove 303 is provided on the rotating plate 302. An adjustable component 304 is disposed in the strip groove 303. One end of the push-pull rod 305 is hinged to the connecting hook 204, and the other end of the push-pull rod 305 is hinged to the outside of the shaft pin 3044.

[0035] As a preferred embodiment of the present invention, the adjustable component 304 includes a screw 3041 rotatably disposed on the inner wall of the strip groove 303. One end of the screw 3041 passes through the rotating plate 302 and is fixedly disposed with a knob 3042. The threads on both ends of the outer wall of the screw 3041 are arranged in opposite directions. Both ends of the screw 3041 are threadedly connected with a threaded sleeve 3043. A shaft pin 3044 is fixedly disposed on the top of the threaded sleeve 3043. A baffle 306 is fixedly disposed inside the strip groove 303. The baffle 306 is located between the two threaded sleeves 3043. The two threaded sleeves 3043 can slide along the inner wall of the strip groove 303.

[0036] As a preferred embodiment of the present invention, the driving device 400 includes a base 401, a motor 402 is fixedly mounted on the bottom of the base 401, a connecting frame 403 is rotatably mounted on the top of the base 401, the connecting frame 403 is fixedly mounted on the bottom of the rotating plate 302, the output shaft of the motor 402 and the bottom end of the connecting frame 403 both penetrate and extend to the inner side of the base 401, and a reciprocating drive assembly 404 is provided between the two.

[0037] As a preferred embodiment of the present invention, the reciprocating drive assembly 404 includes two symmetrically distributed and rotatably disposed within the base 401. A first gear disk 4042 is fixedly sleeved on the output shaft of the motor 402. A second gear disk 4043 that meshes with the first gear disk 4042 is fixedly sleeved on the outer wall of each of the two shafts 4041. A third gear disk 4044 is fixedly sleeved at one end of the connecting frame 403 located inside the base 401. A half gear disk 4045 that meshes with the third gear disk 4044 is fixedly sleeved on the outer wall of each of the two shafts 4041.

[0038] As a preferred embodiment of the present invention, two half-tooth disks 4045 are arranged in the same direction and located above the second tooth disk 4043. The two half-tooth disks 4045 alternately mesh with the third tooth disk 4044 to make the third tooth disk 4044 reciprocate.

[0039] Working principle and usage process of this invention:

[0040] Depending on the required pipe length, the screw 3041 is rotated by the knob 3042. The screw 3041 causes the two threaded sleeves 3043 to move closer or further apart through the threaded transmission. The threaded sleeves 3043 drive the push-pull rod 305 through the shaft pin 3044, which in turn drives the sliding plate 202 through the connecting hook 204 to adjust the initial position of the alignment plate 201 via the connecting rod 203. As the position of the threaded sleeves 3043 changes within the slot 303, the stroke of the alignment plate 201 changes when the rotating plate 302 rotates. Thus, by adjusting the initial position and stroke of the alignment plate 201, it is suitable for aligning pipes of different lengths in batches.

[0041] After completing the above operations, firstly, the pipe can be placed directly on the inclined support 100. Through the action of the inclined support 100 and the conveying roller 102, the pipe is initially sorted by gravity, and the pipe is located between the two alignment plates 201.

[0042] Subsequently, the motor 402 is turned on to drive the first gear disk 4042 to rotate. The first gear disk 4042 drives the two second gear disks 4043 to simultaneously drive the two rotating shafts 4041 to rotate. Simultaneously, the rotation of the two rotating shafts 4041 drives the two half-gear disks 4045 to rotate. The two half-gear disks 4045 alternately mesh with the third gear disk 4044, causing the third gear disk 4044 to drive the connecting frame 403 to reciprocate. The connecting frame 403, in turn, drives the rotating plate 302 to reciprocate under the support of the rotating ring 301. The ring, via the threaded sleeve 3043 and the shaft pin 3044, drives the push-pull rod 305 to reciprocate the moving plate, thereby causing the alignment plate 201 to reciprocate along the length of the upper inclined support 100. The two symmetrically arranged alignment plates 201 align the end faces of the pipes on the upper inclined support 100, ensuring the pipes are centered on the upper inclined support 100. There is no misalignment between adjacent pipes, eliminating the need for manual handling and facilitating subsequent pipe flipping, material conveying, and other orderly processes. In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature. Furthermore, "above," "on top of," and "over" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
