Description

Technical Field

[0001] The invention relates to the technical field of PE pipe laying, and in particular to a pipeline laying device which is easy to operate. Background Art

[0002] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc. are all PE. HDPE is a highly crystalline, non-polar thermoplastic resin. The original HDPE is milky white in appearance and translucent to a certain extent in a thin cross section. PE hose is made of monomer ethylene polymerization, suitable for field irrigation in various types of irrigation areas, and widely used in urban and rural water supply and drainage projects. Adapt to a variety of terrains and climate changes.

[0003] There are existing pipeline lowering devices that are easy to operate, such as a PE coil lowering device disclosed in Chinese patent application CN219689003U, which records: the operation of the motor drives the first reciprocating screw and the first sprocket to rotate, the rotation of the first sprocket drives the second sprocket and the second reciprocating screw to rotate, the rotation of the first reciprocating screw and the second reciprocating screw drives the two sleeves and the electric push rod to move, and when the two electric push rods 10 move to the uppermost position, the electric push rods 10 are controlled to extend so that the two clamps 11 clamp and fix the PE pipe to the lower pipe.

[0004] When the above-mentioned easy-to-operate pipeline lowering device is in use, the reciprocating screw is driven to rotate by the output end of the motor so that the sleeve drives the electric push rod to slide the PE hose clamped by the electric push rod downward, and the PE hose is released after the sleeve moves to the end of the reciprocating screw. Since the sleeve drives the electric push rod to slide along the end of the reciprocating screw to the top end to continue clamping the lower pipe, the sleeve drives the electric push rod to rise in the process, and the PE hose cannot continue to move between the upper and lower support plates, which will cause the production line to stagnate or the production efficiency to decrease. The slow transportation speed will cause the material to stay in the pipeline for too long, increasing energy consumption and transportation costs, and when the electric push rods on both sides push the clamping plates to clamp the PE hose, the PE hose will be squeezed to cause it to be partially deformed and flattened, which is more likely to be twisted or deformed when the lower pipe is laid, resulting in more adjustments and attention during installation.

[0011] As a preferred solution of the easy-to-operate pipeline lowering device of the present invention, the upper surface of the lower supporting plate is connected to an extrusion frame, and the upper surface of the extrusion frame is connected to a fixed top block.

[0012] As a preferred solution of the easy-to-operate pipeline lowering device described in the present invention, the hose recovery mechanism includes a driving disc connected to one side of the rotating roller, a belt is sleeved on the driving disc, one end of the belt is sleeved on a driven disc, and one side of the driven disc is connected to a turntable.

By pushing the limit baffle to slide along the upper surface of the limit plate, it can be adjusted accordingly according to the flatness of the PE hose. When the adjustment slide columns on both sides of the extrusion slide plate slide to the left along the buffer groove block to extrude the buffer spring, the force of the extrusion slide plate to slide and extrude the flat PE hose is controlled. Restoring the shape of the flat hose makes the laying process faster and more efficient. Restoring the shape of the flat hose can ensure the stability of the pipeline, reduce the risk of leakage or damage due to deformation or twisting of the pipeline, and make it easier to adapt to complex terrain or limited installation space.

[0028] The present invention will be further described below in conjunction with the embodiments.

One end of the rack 206 is connected to a driving slider 207 that can be driven to clamp, and the end of the rack 206 away from the driving slider 207 is connected to a limiting slide 208 that can limit the rack 206. One end of the lower tube clamp 1 202 and the lower tube clamp 203 are both fixedly connected to the gear 204, and the two ends of the rack 206 are respectively fixedly connected to the driving slider 207 and the limiting slide 208. The PE hose 201 contacts the driving slider 207 to push the rack 206 to slide to the right, and at the same time drive the lower tube clamp 203 and the lower tube clamp 1 202 on both sides to clamp the PE hose 201.

[0031] The limiting slide 208 is slidably connected to a clamping frame 209 on both sides, and a limiting groove 210 is provided on the clamping frame 209 for limiting the limiting slide 208. A reset spring 211 is provided between the limiting slide 208 and the clamping frame 209. The T-shaped sliders on the upper and lower sides of the limiting slide 208 will slide along the limiting groove 210 provided on the inner wall of the limiting slide 208 corresponding to the clamping frame 209 to limit the rack 206 and the driving slider 207.

[0032] A section of the clamping frame 209 away from the torsion spring shaft 205 is connected to a conveyor belt 212, one end of the conveyor belt 212 is sleeved with a rotating roller 213, and the end of the conveyor belt 212 away from the rotating roller 213 is sleeved with a rotating roller 214. The conveyor belt 212 rotates between the rotating roller 1 213 and the rotating roller 2 214 to drive the lower tube clamp 1 202 and the lower tube clamp 2 203 spaced apart on the conveyor belt 212 to clamp the PE hose 201 continuously.

When the lower tube clamp drives the PE hose 201 to move above the lower support plate 100, the driving slider 2 07 will slide in contact with the inclined surface on one side of the fixed top block 216 and push up, pushing the driving slider 207 to slide to the right again, so that the rack 206 is disengaged from the gears 204 originally meshed on both sides, and the torsion spring shaft 205 simultaneously drives the lower tube clamp 1 202 and the lower tube clamp 2 203 connected by the torsion spring to open, so that the PE hose 201 passes between the lower tube clamp 1 202 and the lower tube clamp 203, and the reset spring piece 211 squeezed between the clamping frame 209 and the rack 206 pushes the limiting slide plate 208 to slide to the left along the limiting slide groove 210 under the reaction force, so that the driving slider 207 drives the lower tube clamp 1 202 and the lower tube clamp 203 on both sides to reset.

[0035] Example 2

[0036] Reference Figure 1-6 , which is the second embodiment of the present invention, provides a pipeline lowering device that is easy to operate, and the hose recovery mechanism 300 includes a driving disc 301 connected to one side of the rotating roller 214, and a belt 302 is sleeved on the driving disc 301, and one end of the belt 302 is sleeved on a driven disc 303, and one side of the driven disc 303 is connected to a turntable 304, and one side of the rotating roller 214 is fixedly connected to the driving disc 301, and one side of the driven disc 303 is fixedly connected to the turntable 304, and the belt 302 is driven by the rotation of the rotating roller 214 to rotate the turntable 304.

[0037] A torsion spring shaft 205 is connected to the side of the turntable 304 away from the driven disc 303, and a sliding rod 306 is rotatably connected to the torsion spring shaft 205. The end of the sliding rod 306 away from the fixed column 305 is connected to a buffer groove block 307, and an adjusting sliding column 308 is slidably connected in the buffer groove block 307. The fixed column 305 on one side is driven by the rotation of the turntable 304 to drive the sliding rod 306 to slide back and forth, and the end of the sliding rod 306 away from the fixed column 305 is fixedly connected to the buffer groove block 307.

[0038] A buffer spring 309 is arranged between the buffer slot block 307 and the adjusting slide column 308. An extrusion slide plate 310 is connected to one side of the adjusting slide column 308. The lower surface of the extrusion slide plate 310 is connected to a limiting slider 311. The limiting slider 311 is slidably connected to the limiting plate 312. The extrusion slide plate 310 at one end is driven to slide along the upper surface of the limiting plate 312 by the reciprocating sliding of the slide rod 306. The flat PE hose 201 is extruded and restored by the extrusion frame 215 and the extrusion slide plate 310 on both sides of the PE hose 201.

[0039] A ratchet plate 313 is symmetrically connected to one side of the limit plate 312, a sliding ratchet block 314 is slidably connected between the ratchet plates 313, an adjustment spring 315 is luxuriously arranged between the sliding ratchet blocks 314, a pressing plate 316 is connected to the upper surface of the sliding ratchet block 314, the sliding ratchet block 314 is slidably connected to a limit baffle 317, the ratchet plate 313 is fixedly connected to one side of the limit plate 312, and the two sides are pressed.

[0040] During use, the belt 302 sleeved on the driving disc 301 on one side is driven to rotate by rotating the second roller 214 to rotate the turntable 304 on the other side. The turntable 304 rotates to drive the fixed column 305 to drive the slide bar 306 to push the extrusion slide plate 310 to slide back and forth along the upper surface of the limit plate 312, and the flat PE hose 201 above the lower support plate 100 is squeezed and restored. By pressing the pressing plates 316 on both sides, the sliding ratchet block 314 below is driven to slide inward to squeeze the adjusting spring 315, so that the sliding ratchet block The plane on one side of 314 is disconnected and conflicts with the plane on one side of the ratchet block plate 313. By pushing the limit baffle 317 to slide along the upper surface of the limit plate 312, it can be adjusted accordingly according to the flatness of the PE hose 201. When the extrusion slide plate 310 slides along the surface of the limit plate 312 and hits the limit baffle 317 to stop sliding, the adjustment slide column 308 will slide to the left along the buffer groove block 307 to squeeze the buffer spring 309, thereby controlling the force of the extrusion slide plate 310 to slide and extrude the flat PE hose 201.
