Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe processing, and in particular to a pipeline conveying device for corrugated pipe processing. Background Art

[0002] Bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes and metal hoses. Metal bellows are mainly used to compensate for pipeline thermal deformation, reduce shock, absorb pipeline settlement deformation, etc. They are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. Corrugated tubes made of other materials such as plastics play an irreplaceable role in media transportation, power threading, machine tools, home appliances and other fields.

[0003] Corrugated pipes are also used in the sewage treatment industry. Considering that buried pipes need to be pressure-resistant, PE double-wall corrugated pipes are generally used to transport sewer sewage. Due to installation and transportation requirements, such corrugated pipes are designed to be assembled by splicing short pipes. The short pipes are generally made by cutting the newly completed long pipes to the same length and are equipped with corresponding connection ports. The diameter of PE double-wall corrugated pipes is large and requires the use of some conveying devices for cutting and conveying.

[0004] The existing PE double-wall corrugated pipe processing and conveying device is relatively ordinary, that is, the conveyor belt that is more common in life. Although the conveyor belt can achieve the cutting and conveying effect of the PE double-wall corrugated pipe, when the PE double-wall corrugated pipe is conveyed and cut, due to the slight shaking of the conveyor belt, a certain position shift will occur, which will affect the neatness of the cutting mouth and is not conducive to the subsequent installation of the PE double-wall corrugated pipe connection port. At the same time, after the PE double-wall corrugated pipe is cut, it is still maintained in a straight line arrangement for transportation. Subsequently, it is necessary to use workers or mechanical arms to transport and arrange the short pipes in a parallel arrangement to facilitate subsequent transportation. It is not labor-saving enough and the handling efficiency is also low. Summary of the invention

[0035] During the specific operation, the whole corrugated pipe is conveyed forward by the conveyor 13, and the corrugated pipe is cut into short pieces by a cutting member, and the cutting member can be a cutting tool (the cutting tool is a conventional prior art).

[0036] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The clamping and conveying mechanism 2 includes a mounting plate 211 arranged above the rear ends of the connecting frame 6 and the transmission frame 5. A plurality of groups of pipe clamping frames 23 are movably arranged on the front side of the mounting plate 211. Each group of pipe clamping frames 23 includes two symmetrically distributed pipe clamping frames 23, and the two pipe clamping frames 23 in the same group are commonly provided with a pipe clamping assembly 22 for controlling them to synchronously approach or move away. The pipe clamping assembly 22 is installed on a connecting seat 24. A plurality of connecting seats 24 are all installed on the same circulation assembly 21 for changing their positions.

[0038] During specific operation, the clamping assembly 22 controls the clamping frame 23 to clamp the cut corrugated short tube, and the connecting seat 24 drives the clamping assembly 22 to change its position along the circulation assembly 21 .

[0039] See also Figure 1 and Figure 8 The transmission component 4 includes a transmission roller 43 that is symmetrically rotated front and back and connected to the transmission frame 5. The two transmission rollers 43 are symmetrically connected to the transmission belts 44. One of the transmission rollers 43 is driven by a driving motor. The outer surface of the transmission belt 44 is fixedly connected with a plurality of connecting pipe seats 42 at equal intervals. The connecting pipe seats 42 are made of rubber, are notched, and the opening of the connecting pipe seats 42 gradually decreases from top to bottom.

[0040] During specific operation, the connecting pipe seat 42 is made of rubber material, which can adapt to the changes of the transmission belt 44. The connecting pipe seat 42 is notched to facilitate the insertion of the corrugated short pipe.

[0041] See also Figure 8 The upper rear end of the transmission frame 5 is fixedly connected with an inclined slide 41 , and the rear end of the inclined slide 41 is fixedly connected with a baffle, and the inclination angle of the baffle is greater than the inclination angle of the inclined slide 41 .

[0042] During specific operation, the transmission roller 43 is controlled to rotate by a driving motor, and the transmission roller 43 drives the transmission belt 44 to rotate. The rotation of the transmission belt 44 is used to change the position of the connecting pipe seat 42, so that different connecting pipe seats 42 continuously pass through the bottom of the inclined slide 41, and the corrugated short tube is supported and transported by the connecting pipe seat 42. The falling corrugated tube is slowly slid into the connecting pipe seat 42 through the inclined slide 41, and the sliding of the corrugated short tube is restricted by the baffle to prevent the corrugated short tube from falling from above the inclined slide 41.

[0043] See also Figure 1 and Figure 3 The centering assembly 11 includes an opening 141 symmetrically opened on the frame 14, a side bracket 119 is fixedly connected to the lower side of the opening 141, a bidirectional screw rod 118 is rotatably connected between the left and right side brackets 119, and a guide rod 111 is also fixedly connected between the left and right side brackets 119. The bidirectional screw rod 118 and the guide rod 111 both pass through the opening 141, and one end of the bidirectional screw rod 118 extends to the outside of one side bracket 119 and is fixedly connected to the output end of the motor 117. The motor 117 is fixedly connected to the outside of the side bracket 119 on one side. A lower connecting plate 112 is symmetrically threadedly connected to the bidirectional lead screw 118, and the lower connecting plates 112 on both sides are slidably connected to the guide rod 111. A plurality of electric push rods 113 are fixedly connected to the upper side of the lower connecting plate 112, and an upper connecting plate 116 is fixedly connected to the output ends of the electric push rods 113 on the same lower connecting plate 112. A plurality of mounting frames 115 are equidistantly fixedly connected to one side of the upper connecting plate 116 close to the central axis of the conveyor 13, and a side abutment roller 114 is rotatably installed in the mounting frame 115, and the middle part of the side abutment roller 114 is recessed inward.

[0044] During specific operation, the motor 117 is used to control the rotation of the bidirectional screw rod 118, and the bidirectional screw rod 118 drives the lower connecting plate 112 to move toward each other along the guide rod 111, so that the lower connecting plates 112 on both sides drive the side abutment rollers 114 to press against the corrugated tube to ensure the flat transportation of the corrugated tube. The electric push rod 113 is used to control the upper connecting plate 116 to drive the side abutment rollers 114 to move up and down, so that the middle part of the side abutment rollers 114 can fit with the corrugated tube, thereby increasing the contact area between the side abutment rollers 114 and the corrugated tube, and further ensuring the concentricity of the corrugated tube.

[0045] See also Figure 1 and Figure 3 The locking assembly 12 includes a ring frame 123 fixedly connected to the rear end of the frame 14 and distributed in pairs in the front-to-back direction. A plurality of seats 122 are equidistantly arranged in the central hole of each ring frame 123. The side of the seat 122 away from the central hole of the ring frame 123 is fixedly connected to the output end of the second electric push rod 121. The second electric push rod 121 is fixedly connected to the side wall of the ring frame 123. A lower cutting edge for cutting the cutting piece is reserved between the two ring frames 123.

[0046] During specific operation, the electric push rod 121 controls the seat 122 to press the two sides of the cutting position of the corrugated tube inserted into the ring frame 123, and the corrugated tube is cut by the lower knife edge.

[0047] See also Figure 4 and Figure 5 The pipe clamping assembly 22 includes an extension plate 221 integrally formed at one end of the pipe clamping frame 23 near the connecting seat 24, a connecting arm 223 is hingedly connected to the outer end of the extension plate 221, a gear 1 224 is fixedly connected to the end of the connecting arm 223 away from the extension plate 221, and the gear 1 224 is rotatably connected in the arch frame 225, a connecting arm 1 222 is also hingedly connected to the end of the pipe clamping frame 23 near the connecting seat 24, and the other end of the connecting arm 1 222 is hinged in the arch frame 225, the connecting arm 1 222 and the connecting arm 2 223 adjacent thereto are distributed in parallel, and a rack 1 227 is meshedly connected between the two gears 1 224, and the rack 1 227 is fixedly connected to the output end of the electric push rod 3 226, and the electric push rod 3 226 is fixedly connected to the inside of the arch frame 225.

[0048] During specific operation, the electric push rod 3 226 is used to control the rack 1 227 to rise or fall, and the rack 1 227 drives the two gears 1 224 to rotate synchronously. The gear 1 224 rotates to control the connecting arm 223 to change its angle, and then the extension plate 221 is controlled to cooperate with the connecting arm 1 222 to drive the two pipe clamping frames 23 to move synchronously to clamp or loosen the corrugated short pipe.

[0049] See also Figure 1 , Figure 4 and Figure 5 The circulation component 21 includes a circulation sprocket 214 which is symmetrically mounted on the front side of the mounting plate 211 for rotation. One side of the circulation sprocket 214 is driven by a motor 213. The motor 213 is fixedly connected to the mounting plate 211. The two circulation sprockets 214 are commonly connected to a circulation chain 212. Several connecting seats 24 are equidistantly fixedly connected to the circulation chain 212. A section of the connecting seat 24 connected to the circulation chain 212 is made of rubber. The length of the circulation chain 212 between the central axes of two adjacent connecting seats 24 corresponds to the distance between the central axes of the transmission frame 5 and the connecting frame 6.

[0050] During specific operation, the circulating sprocket 214 on one side is controlled by motor 213 to rotate, driving the circulating chain 212 to rotate, and then driving each connecting seat 24 to change position synchronously. A section where the connecting seat 24 is connected to the circulating chain 212 is made of rubber material. When the connecting seat 24 passes through the curved section of the circulating chain 212, the connecting seat 24 can elastically expand and contract to automatically adapt to the curvature change of the circulating chain 212. The length of the circulating chain 212 between the central axes of two adjacent connecting seats 24 is set to correspond to the distance between the central axes of the transmission frame 5 and the connecting frame 6, which can ensure the coordinated work of the locking component 12 and the transmission component 4, so that the corrugated short tube can be accurately placed on the transmission component 4.

[0051] See also Figure 6 The direction adjustment component 25 includes a connecting rod (not shown in the figure) fixedly connected to the side of the arch frame 225 close to the connecting seat 24.

The rack 252 is fixedly connected to the output end of an electric push rod 4 253. The electric push rod 4 253 is fixedly connected to the interior of the connecting seat 24. Each connecting seat 24 and the mounting plate 211 are jointly provided with a control component 254 for controlling the clamping and steering of the corrugated short tube.

[0052] During operation, the electric push rod 4 253 controls the rack 252 to move, thereby driving the gear 251 to rotate. The gear 251 drives the connecting rod to control the arch frame 225 to drive the clamping assembly 22 to rotate 90° as a whole, thereby changing the placement direction of the corrugated short tube.

[0053] See also Figure 1 , Figure 5 and Figure 7 The control component 254 includes an infrared transmitter 2541 fixedly connected to the center of the rear side of each connecting seat 24, and the control component 254 also includes an infrared receiver four 2545 and an infrared receiver one 2542 fixedly connected to the upper and lower sides of the center of the mounting plate 211. The lower side of the mounting plate 211 corresponds to the central axis position of the transmission frame 5 and the connecting frame 6 and is fixedly connected with an infrared receiver two 2543 and an infrared receiver three 2544 respectively.

When the infrared transmitter 2541 on any connecting seat 24 is opposite to the infrared receiver 2 2543, the controller controls the electric push rod 3 226 in the tube clamping assembly 22 of the connecting seat 24 to run, and the clamped corrugated short tube is loosened. When the infrared transmitter 2541 on any connecting seat 24 is opposite to the infrared receiver 4 2545, the controller controls the electric push rod 4 253 and the electric push rod 3 226 in the connecting seat 24 to run, and the tube clamping frame 23 is reset and turned 90 degrees.

[0055] See also Figure 1 and Figure 4 The moving component 31 includes a sliding rod 312 that slides through the lower ends of the left and right brackets 3.

One side bracket 3 is also fixedly connected to the output end of the electric push rod 5 311, and the electric push rod 5 311 is fixedly connected to the transmission frame 5.

[0056] During specific operation, the electric push rod 5 311 is used to control the bracket 3 to slide along the slide rod 312, so that the mounting plate 211 moves forward and backward as a whole, so that the pipe clamping frame 23 can be moved to the middle of the corrugated short tube in a controllable manner according to the length of the sheared corrugated short tube, thereby preventing the corrugated short tube from being clamped and skewed.

[0057] When in use: S1: place the entire corrugated pipe on the conveyor 13, and then convey the entire corrugated pipe forward through the conveyor 13. During transportation, the bidirectional screw rod 118 is controlled to rotate by the motor 117, and the bidirectional screw rod 118 drives the lower connecting plate 112 to move along the guide rod 111, so that the lower connecting plates 112 on both sides drive the side rollers 114 to limit the support of the corrugated pipe to ensure the flat transportation of the corrugated pipe.
