Abstract
The invention relates to a universal hoisting jack for pulling and pressing. On the basis of basic structure of the ordinary hoisting jack, the front part of a one-way oil inlet ball valve is connected with a converse diversion pipe; a transfer switch is arranged between the converse diversion pipe and the on-way oil inlet ball valve; two same U-type ventilating pipes are respectively arranged on the inner wall of the outer housing of an oil storage chamber in parallel in a reversing manner; ventilating holes at one end of each U-type ventilating pipe penetrate through the outer housing and are communicated with the atmosphere, and an automatic adjusting ball valve of the oil storage chamber for keeping balance to the pressure of the atmosphere is arranged at the other end of each U-type ventilating pipe; and springs are additionally arranged on the one-way oil inlet ball valve and a one-way oil outlet ball valve. Based on basic structure and functions of the existing hoisting jack, and simultaneously the limit that the traditional hoisting jack is incapable of being used in a handstand or horizontal manner is also changed, so that the universal hoisting jack is suitable for various construction conditions. After a working stand is installed, various construction applications such as pushing, pulling, jacking and pressing can be realized.
Description
Technical field
The present invention be a kind of a kind of needs that relate to transport vehicle, construction machinery and equipment and equipment in maintenance, dismounting or often use when installing can be vertical, horizontally-inclined or the jack that stands upside down and use, have simultaneously the several functions such as push-and-pull top pressure.
Background technology
Often running into when transport vehicle, construction machinery and equipment and maintenance of equipment, dismounting or installation need to be by certain dismounting or the installation process that pushes away, draws, pushes up, presses, yet often because instrument standby and uneven and neat and off guard reason, cause the delay engineering progress, even cause parts to damage; The instrument that is used for now dismounting and so on market is various in style, and style is different, but following several shortcoming is arranged on its structure: that 1, can dismantle can not install again; That 2, can install can not dismantle again; 3, the energy push-and-pull can not push up pressure again; 4, can push up press again can not push-and-pull; 5, the energy vertical top can not fall again to press; 6, can fall press again can not vertical top.The above-mentioned defective that is subject to various usage conditions is all because the reason of structure can not satisfy the dismounting of the various different modes of various complex conditions or the demand of field engineering far away.
Summary of the invention
The present invention is take the basic structure of existing jack and function as the basis, take existing press and the purposes of drawing code as guiding, its objective is change traditional jack can not horizontally-inclined and the limitation used and can not push away, draw, push up, press of standing upside down, total defective, enable to adapt to multi-form execution conditions and be fit to multi-form dismounting purposes simultaneously.
