Technical solution of the present invention is described in detail in the following with reference to the drawings and specific embodiments, to be further understood that
The purpose of the present invention, scheme and effect for ease of description and understand that the present invention makees following agreement: with steel pipe row during plastic-coated
Into direction define " upstream " and " downstream ", steel pipe is from " upstream " flow direction " downstream " in plastic spraying.In description of the invention
The indicating positions such as "upper", "lower" " left side " " right side " or positional relationship are positional relationship based on the figure, are only easy for description originally
The technical solution of invention, and be not considered as limiting the invention.
As Fig. 1 to Fig. 3 it is common shown in dual-purpose small-caliber steel pipe plastic-coated equipment, position between pre-temperature furnace 20 and curing oven 50
It installs and is equipped with guide rail framework 70, guide rail framework 70 is lifted with the steel pipe grabbing device moved along guide rail driven by power device
71；Ground between the pre-temperature furnace 20 and curing oven 50 digs the installation pond 42 of leaching well 30 and the coating machine 40 that dusts downwards,
The tool of pond 42 is installed there are four pool wall, be respectively along the direction of travel A of the steel pipe H upstream pool wall 421 arranged and downstream pool wall 422 with
And left end pool wall 423 corresponding with two end positions of steel pipe H and right end pool wall 424, leaching well 30 and installation pond 42 are arranged in
Between the discharge end of pre-temperature furnace 20 and the feed end of curing oven 50.
The fuselage for dusting coating machine 40 be provided with the coating machine 40 that dusts from lifting device 41 fuselage have respectively with
Upstream pool wall 421, downstream pool wall 422, left end pool wall 423 upstream side corresponding with 424 position of right end pool wall in pond 42 are installed
Portion 401, downstream side portion 402, left part 403 and right part 404；
The coating machine 40 that dusts as shown in Figures 4 to 6 from lifting device include: upper transmission shaft 412 and lower drive shaft
413, the left part 403 and right part 404 of fuselage, which rotate, is provided with transmission shaft 412 and lower drive shaft 413, lower drive shaft
413 both ends are installed with lower sprocket 414 respectively, and the both ends of upper transmission shaft 412 are installed with upper sprocket wheel 415, each pair of lower sprocket respectively
Elevating chain 416 is arranged between 414 and upper sprocket wheel 415, each elevating chain 416 corresponding with 423 position of left end pool wall
One chain side is fixed on the top of left end pool wall 423, and the one of each elevating chain 416 corresponding with 424 position of right end pool wall
A chain side is fixed on the top of right end pool wall 424；Specifically, elevating chain 416 is solid by elevating chain fixing seat 419 and pool wall
Fixed, the fixation position of elevating chain fixing seat 419 determines the adjustable height for the coating machine 40 that dusts.
Driving device is fixed on the lower part of fuselage and is sequentially connected with lower drive shaft 413.Further, driving device is electricity
Machine 417, motor 417 are connect with 413 chain conveyer of lower drive shaft.
It installs and is respectively fixed with guide groove device, the upstream side of fuselage on the upstream pool wall 421 and downstream pool wall 422 in pond 42
Portion 401 and downstream side portion 402 are respectively arranged with guide rail 418, and guide rail 418 is constrained in the guide groove 411 of guide groove device.
It is as follows from the lifting principle of lifting device 41:
It is rotated from the motor driven lower drive shaft 413 of lifting device 41, drives the lower sprocket 414 at 413 both ends of lower drive shaft
Rotation, since the wheelbase between upper transmission shaft 412 and lower drive shaft 413 is constant, that is, upper sprocket wheel 415 and lower sprocket 414 it
Between center away from constant, and a chain side of elevating chain 416 is fixed on left end pool wall 423 or right end pool wall 424, so,
When motor 417 turns clockwise, lower sprocket 414 is creeped downwards along the fixation chain side of elevating chain 416, when lower sprocket 414 to
Creep under as soon as chain link when, fuselage is lowered the height of a chain link；Similarly, when motor 417 rotates counterclockwise, lower sprocket
414 creep upwards along the fixation chain side of elevating chain 416, as soon as when lower sprocket 414 creeps chain link upwards, fuselage is lifted
The height of a high chain link.Self-locking device (not shown) is had on motor 417, when fuselage rises to ground or more, electricity
Machine 417 stalls self-locking device, and motor 417 is locked to prevent fuselage from gliding.
Well 30 is soaked in the present embodiment and is located at upstream side, and installation pond 42 is located at downstream side.As Fig. 1 to Fig. 3 it is common shown in two
It is disposed with according to the process flow of production from upstream to downstream with small-caliber steel pipe plastic-coated equipment: feeder 10, pre-temperature furnace
20, well 30, the coating machine 40 that dusts, curing oven 50 and cooling frame 60 are soaked.
Dual-purpose small-caliber steel pipe plastic-coated equipment alternative realizes the steel to diameter between (DN70mm~DN400mm)
Pipe carries out dip-coating plastic-coated and spraying plastic-coated.The course of work is as follows:
When carrying out dip-coating plastic-coated to small-caliber steel pipe, the coating machine 40 that dusts at this time is in off working state, such as Fig. 4 and figure
Shown in 5, by droping in installation pond 42 from lifting device 41, the top covering in installation pond 42 is used as to supply the coating machine 40 that dusts
The cover board of worker's walking, leaching well 30 is in running order, and leaching well 30 is provided with the coating of plastic-coated, brings out from the discharging of pre-temperature furnace 20
The heating steel pipe H come is moved in leaching well 30 with the mode of driving (driving is equipped with lift up rapidly device) and human assistance and is soaked
It applies, then, then by steel pipe H driving quickly proposition, by the steel pipe H after dip-coating, the entrance of curing oven 50 is moved to by human assistance
Place is sent into curing oven 50 by carrier chain and carries out heating cure, and the steel pipe H after solidification transfers out curing oven 50, subsequently into repairing
Mend area's repairing, finally packaging delivery.
When carrying out spraying plastic-coated to small-caliber steel pipe, well lid is covered on leaching well 30, leaching well 30 is in off working state, and
By install pond 42 top covering cover board remove, as shown in fig. 6, dust coating machine 40 by from lifting device 41 from installation pond 42
It rises on ground, steel pipe grabbing device 71 movement such as moves by up and down, along guide rail bracket 70, will go out from pre-temperature furnace 20
Material brings out the heating steel pipe H crawl come, and then steel pipe H is put into the coating machine 40 that dusts and is sprayed, after the completion of spraying, steel
Steel pipe H after dip-coating is moved to the entrance of curing oven 50 by pipe grabbing device 71, is sent into curing oven 50 and is heated by carrier chain
Solidification, the steel pipe H after solidification transfer out curing oven 50, and subsequently into patch area repairing, finally packaging is delivered.Steel pipe grabbing device
71 structure type is varied, be it is well known to those of ordinary skill in the art, this will not be repeated here.
Dual-purpose small-caliber steel pipe plastic-coated equipment of the invention can selectively realize dip-coating plastic-coated and spraying plastic-coated, reduce and account for
Ground area, reduces the capital investment of equipment, to reduce production cost.
The present invention is not limited to the above embodiment, all are made based on design of the invention, principle, structures and methods
Various improvement, all within protection scope of the present invention.
