Description

Hot-expanding steel tube is used feeding device

Technical field

The utility model relates to a kind of steel pipe feeding device, especially relates to a kind of hot-expanding steel tube and uses feeding device.

Background technology

Seamless steel pipe is a mother tube, and mother tube need be inserted in mother tube on the core bar, thereby carry out the preparation of producing hot-expanding steel tube carrying out heat expansion first being processed, and above-mentioned work is referred to as material loading.Adopt hanging device to add the artificial way that cooperates in the prior art and accomplish, because there is certain potential safety hazard in all operations aloft of its mother tube during the mother tube lifting, not only inefficiency but also poor stability, working strength of workers is also bigger.

Summary of the invention

The problem that the utility model will solve provides that a kind of equipment investment is little, energy consumption is low, high efficiency, safety coefficient are high, and the hot-expanding steel tube that can use manpower and material resources sparingly greatly use feeding device, carries out the material loading use when especially being fit to produce hot-expanding steel tube.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of hot-expanding steel tube is used feeding device, comprises inclined-plane, hydraulic cylinder, lifting wheel, vehicle frame, V-type roller; The two ends of said bottom of frame are equipped with a lifting wheel, with an all fixing inclined-plane on the corresponding ground of said lifting wheel; Said vehicle frame bottom is connected with a hydraulic cylinder, and the said hydraulic cylinder other end fixes on the ground; Said vehicle frame upper end is provided with the plurality of V forming roll, and an end of said V-type roller is connected with reductor.

Further, the next door of said feeding device also is provided with the gantry beams pipe more than three, and said gantry beams pipe is fixed through the column that fixes on the ground, and the parallel axes of the center line of gantry beams pipe and V-type roller.

Further, the quantity of said V-type roller is 4.

Further, said hydraulic cylinder is located at the midway of vehicle frame.

Advantage and the good effect that the utlity model has are:

At the disposable mother tube of putting sufficient amount of gantry beams Guan Shangke, reduce the frequency of usage of hanging device, thereby energy consumption is low, high efficiency, safety coefficient are high;

Mother tube can be rolled to V-type roller top through the gantry beams pipe; Because the coefficient of rolling friction of mother tube is far smaller than its coefficient of sliding friction, so the artificial rolling transport that can accomplish mother tube is avoided aerial handling; Reduce potential safety hazard, guarantee employee's safety;

Because the V-type roller has automatic adjustment center function, good to neutrality, rotate at the V-type roller, drive mother tube by frictional force and move ahead, get into heat and expand in the process of station, make mother tube be inserted in smoothly on the core bar and change subsequent processing over to;

Not only equipment investment is little, energy consumption is low in the use of the utility model, high efficiency, safety coefficient high, and can use manpower and material resources sparingly greatly, makes the mother tube material loading in the hot-expanding steel tube process convenient; Have simple in structure, practical safety, production efficiency advantages of higher.

The specific embodiment

Like Fig. 1, shown in 2, a kind of hot-expanding steel tube of the utility model is used feeding device, comprises inclined-plane 1, hydraulic cylinder 2, lifting wheel 3, vehicle frame 4, V-type roller 5; The two ends of said vehicle frame 4 bottoms are equipped with a lifting wheel 3, with an all fixing inclined-plane 1 on the said lifting wheel 3 corresponding ground 10; Said vehicle frame 4 bottoms are connected with a hydraulic cylinder 2, and said hydraulic cylinder 2 other ends are fixed on the ground 10; Said vehicle frame 4 upper ends are provided with plurality of V forming roll 5, and an end of said V-type roller 5 is connected with reductor 6.

Preferably, the next door of said feeding device also is provided with the gantry beams pipe 7 more than three, and said gantry beams pipe 7 is fixing through the column 8 that is fixed on the ground 10, and the parallel axes of the center line of gantry beams pipe 7 and V-type roller 5.

Preferably, the quantity of said V-type roller 5 is 4.

Preferably, said hydraulic cylinder 2 is located at the midway of vehicle frame 4.

The course of work of this instance: with crane mother tube 9 is placed on the gantry beams pipe 7, on gantry beams pipe 7, can disposablely put the mother tube 9 of sufficient amount, reduce the frequency of usage of hanging device; Thereby energy consumption is low, high efficiency, safety coefficient high, and at this moment, V-type roller 5 is under the last plane of gantry beams pipe 7; Mother tube 9 is rolled on the V-type roller 5, because the coefficient of rolling friction of mother tube 9 is far smaller than its coefficient of sliding friction, so the artificial rolling transport that can accomplish mother tube 9; Avoid aerial handling, reduce potential safety hazard, guarantee employee's safety; Primer fluid cylinder pressure 2 work then, lifting wheel 3 will drive vehicle frame 4 and 1 move upward along the inclined-plane, when moving to position as shown in Figure 2; Start reductor 6 and drive 5 rotations of V-type roller, because it is V-type roller 5 has automatic adjustment center function, good to neutrality; V-type roller 5 rotates, and drives mother tube 9 by frictional force and moves ahead, and gets into heat and expands in the process of station; Make mother tube 9 be inserted in the material loading of accomplishing mother tube 9 on the core bar smoothly, thereby change subsequent processing over to.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
