In the lifting conveying device for the tubing, the tubing can be synchronously supported from a support object, and the conveying rollers simultaneously rotate to forward or backward convey the tubing to finish the line production of tubing processing; the labor strength of workers can be greatly reduced; and the degree of automation is high. The lifting conveying device for the tubing has the characteristic of simple and compact structure.

Description

Pipe material elevating transport apparatus

Technical field

Pipe material process equipment of the present invention specifically is a kind of pipe material elevating transport apparatus.

Background technology

In the prior art, to the conveying of pipe material, adopt car handling or artificial mode of passing usually and will manage and expect that the end sends into process equipment, this mode inefficiency, labor strength are big, and automaticity is extremely low.

Summary of the invention

The objective of the invention is to overcome the deficiency that exists in the prior art; A kind of pipe material elevating transport apparatus is provided; A plurality of conveying running rollers are at the effect synchronization lifting of pull bar in this device; To manage material and hold up from supporter, a plurality of conveying rollers rotate simultaneously will manage material conveying forward or backward, accomplish the continuous productive process of pipe material processing.

The technical scheme that the present invention adopted is following:

A kind of pipe material elevating transport apparatus, the pipe material is carried by the axial plurality of V shape conveying roller of tubular axis, and having place's conveying roller at least is live roll, is rotated by motor-driven;

Swing arm top in the middle of conveying roller is arranged on, lifting platform comprises the middle swing arm and the both sides axis of guide at middle part, the axis of guide is slippage up and down in being fixed in the guide pin bushing of elevating bracket;

Middle swing arm lower ending pivot is connected on square and holds up on the angle point of arm, and another angle point that holds up arm is articulated on the pull bar, holds up upper-arm circumference and turns round around middle angle point;

Several held up arm before and after pull bar connected successively, and pull bar one end is connected on the piston rod of hydraulic cylinder;

Limiting bracket and limit switch are separately positioned on pull bar and the hydraulic cylinder.

The present invention can hold up the pipe material from supporter synchronously, and a plurality of conveying rollers rotate simultaneously will manage material conveying forward or backward, accomplish the continuous productive process of pipe material processing; Can reduce labor strength greatly, automaticity is high, and has simple in structure, compact characteristics.

The specific embodiment

Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.

Like Fig. 1 to shown in Figure 3: the present invention mainly by elevating bracket 1, jackshaft 2, middle swing arm 3, hold up arm 4, turning cylinder 5, pitman shaft 6, pull bar 7, power elevating bracket 8, limiting bracket 9, hydraulic cylinder 10, limit switch 11, regulating shaft 12, regulate earrings 13, regulate earrings axle 14, the axis of guide 15, down fairlead 16, holder axle 17, go up fairlead 18, holder 19, running roller seat 20, bearing 21, conveying roller 22, reductor 23, motor 24 etc. and constitute.

The present invention adopts picking-up arm 4 to be loaded on elevating bracket 1 and the power elevating bracket 8 through turning cylinder 5, holds up arm 4 and is connected with pull bar 7 with middle swing arm 3 respectively through jackshaft 2, pitman shaft 6, and middle swing arm 3 is connected with holder 19 through holder 17; Holder 19 is loaded on the running roller seat 20; Running roller seat 20 two ends divide to connect the axis of guide 15, and following fairlead 16 and last fairlead 18 are packed in elevating bracket 1 and the power elevating bracket 8, and the axis of guide 15 inserts to be gone up in fairlead 18 and the following guide pin bushing 16; Conveying roller 22 two ends are equipped with bearing 21 and are fixed on the running roller seat 20; Motor 24, reductor 23 are connected and fixed on the running roller seat 20 with conveying roller 22, and limiting bracket 9 is contained on the pull bar 7, and hydraulic cylinder 10 is connected with pull bar 7; Limit switch 11 is loaded on the hydraulic cylinder 10; Regulate earrings 13 and be connected with hydraulic cylinder 10 through regulating earrings axle 14, regulate earrings 13 and screw in the regulating shaft 12, regulating shaft 12 is installed on power elevating bracket 8 afterbodys.

The pipe material is carried by the axial plurality of V shape conveying roller 22 of tubular axis, has place's conveying roller 22 at least for live roll, is rotated by motor-driven; The top of swing arm 3 in the middle of conveying roller 22 is arranged on, lifting platform comprise the middle swing arm 3 and the both sides axis of guide 15 at middle part, and the axis of guide 15 is slippage up and down in the guide pin bushing that is fixed in elevating bracket 1 18; Middle swing arm 3 lower ending pivots are connected on square and hold up on the angle point of arm 4, and another angle point that holds up arm 4 is articulated on the pull bar 7, hold up arm 4 and turn round around middle angle point; Several held up arm 4 before and after pull bar 7 connected successively, and pull bar 7 one ends are connected on the piston rod of hydraulic cylinder 10; Limiting bracket 9 is separately positioned on pull bar 7 and the hydraulic cylinder 10 with limit switch 11.

The course of work of the present invention is following: primer fluid cylinder pressure 10, and a plurality of picking-up arms 4 are that gyroaxis rotates with middle angle point simultaneously under the effect of pull bar 7, middle swing arm 3 deflections are risen, and a plurality of conveying rollers 22 are risen synchronously, will manage material and from supporter, hold up synchronously; Actuating motor 24, a plurality of conveying rollers 22 rotate simultaneously will manage material conveying forward or backward, accomplish the continuous productive process of pipe material processing.
