The middle support is formed by welding two square long steel pipes I and one square short steel pipe I, the long steel pipe I is installed in the slide way and can slide, a plurality of pin shaft holes with the same specification as the slide way are formed in the long steel pipe I, the outer side of the bottom of the long steel pipe I is welded with the lifting plate, the lifting plate is sleeved on the outer side of the notch of the slide way, and the lifting plate synchronously slides when the long steel pipe I slides in the slide way; the middle of the short steel pipe I is provided with a fixture mounting hole, the upper part of the fixture is made into a proper shape according to different supported objects, and the lower part of the fixture is provided with a pin shaft which is arranged on the mounting hole.

The upper bracket comprises a support arm, a profile frame and a sleeve, wherein the support arm is formed by welding two long and short square steel pipes into a right-angled shape, the long steel pipe of the support arm is provided with a plurality of pin shaft holes with the same specifications as a slide way, the long steel pipe of the support arm is assembled in the long steel pipe I of the middle bracket and can slide, the short steel pipe of the support arm is installed in the sleeve, and the profile frame installation hole is formed in the middle of the upper part of the sleeve.

The base and the middle support are assembled to form a jack support, the support is arranged at a working position, the jack is arranged between the bottom plate and the short steel pipe I, when the jack works, the short steel pipe I is supported to drive the long steel pipe I to slide in the slideway, then the heavy object on the profile frame or the heavy object on the lifting plate correspondingly moves, and after the heavy object moves to a proper position, the heavy object penetrates through a corresponding pin shaft hole by a pin shaft to be fixed; and when the lifting operation is required to be continued, the pin shaft is taken out, the height of the jack is adjusted, and the lifting operation is continued.

When the jack support of base and middle support assembly highly can not satisfy the operation requirement, with the upper bracket assembly to the middle support on, during operation can adjust the upper bracket to suitable high back with the round pin axle with the upper bracket fixed with the middle support, the jack is put and is carried out work between bottom plate and short steel pipe I.

When the upper bracket does not need to be assembled to the middle bracket, the two support arms of the upper bracket can be used as the support bracket.

Detailed Description

As shown in the attached drawings, the jack support comprises a base 1, a middle support 2 and an upper support 3, wherein the base 1 comprises a bottom plate 4 and a slide way 5, the slide way 5 is two square steel pipes, a plurality of pin shaft holes are formed in the steel pipes, a groove is formed in the middle of one surface of each steel pipe, the bottom plate 4 is a rectangular iron plate, and the groove surface of each steel pipe faces outwards and is vertically welded in the middle of the short side of the bottom plate 4.

The middle support 2 is formed by welding two square long steel pipes I7 and a square short steel pipe I8, the long steel pipe I7 is installed in the slide way 5 and can slide, a plurality of pin shaft holes with the same specification as the slide way 5 are formed in the pin shaft holes, the lifting plate 6 is welded on the outer side of the bottom of the long steel pipe I7, the lifting plate 6 is sleeved on the outer side of the slotted position of the slide way 5, and when the long steel pipe I7 slides in the slide way 5, the lifting plate 6 synchronously slides; the middle of the short steel pipe I8 is provided with a mounting hole of a jig 9, the upper part of the jig 9 is made into a proper shape according to different supported objects, and the lower part of the jig 9 is provided with a pin shaft which is mounted on the mounting hole.
