Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the embodiments and the accompanying drawings.
Referring to fig. 1, the operation frame 1 is a trapezoidal hollow support, and universal wheels 1-1 are mounted at four corners of the bottom of the operation frame. Two opposite side surfaces of the operation frame 1 are respectively welded with two opposite vertical connecting rods in the vertical direction, and the other two opposite side surfaces of the operation frame 1 are respectively welded with two horizontal connecting rods from top to bottom. A set of opposite vertical connecting rods is selected, a horizontal connecting rod is welded at the same height as the horizontal connecting rod at the lower side of the outer part, and a horizontal connecting rod is also welded at the top of the set of vertical connecting rods. A supporting plate is welded in the middle of the inner lower side horizontal connecting rod and the outer lower side horizontal connecting rod which is at the same height, and a lifting oil cylinder 2 is arranged at the connecting part of the supporting plate and the inner lower side horizontal connecting rod. Two hydraulic rubber pipes are arranged on the lifting oil cylinder 2 and are respectively connected to a hydraulic control operating handle 3 of the lifting oil cylinder, and the height of the lifting oil cylinder 2 is controlled by the hydraulic control operating handle 3 of the lifting oil cylinder. The top of the lift cylinder 2 is welded with a bolt, a nut is screwed on the bolt, and another annular component (for example, a nut) is welded below the nut and is used for a cable to pass through for suspension. The cable passes around two pulleys provided at the top of the handling frame 1 and lifts the jack-action auxiliary sleeve device 6 by means of a ring-shaped member (for example, a nut) welded on top of the jack-action auxiliary sleeve device 6 additionally installed outside the jack 5, the jack-action auxiliary sleeve device 6 being confined in the space formed by the two sets of vertical connecting rods. The jack 5 is also additionally provided with a rotatable connector 7, and the rotatable connector 7 is provided with a T-shaped opening for placing bolts with different sizes and is connected with a connecting shaft to be disassembled through the bolts. Two hydraulic rubber pipes are arranged on the jack 5 and are respectively connected to the jack hydraulic control operating handle 3. The lifting oil cylinder hydraulic control operating handle 3 and the jack hydraulic control operating handle 3 form a group of handles which are arranged on a connecting plate welded between two horizontal connecting rods together and respectively control the actions of the lifting oil cylinder 2 and the jack 5.
In the embodiment, the emulsion pump of BRW200/31-5 type is adopted to provide power for the hydraulic support connecting shaft dismounting device. The jack with 700mm of stroke (expansion amount) and 69KN of contraction force is selected, and the jack and the operating handle are ZY4800/13/32 type bracket accessories for restoration.
The embodiment of the utility model provides a working process as follows:
when the hydraulic support connecting shaft needs to be detached, firstly, the operating frame 1 is moved to a target position, and the universal wheels are rotated to adjust the direction. And hydraulically controlling operating handles 3 and 4 of the lifting oil cylinder to be connected to an emulsion pump through a hydraulic rubber tube. And starting an emulsion pump, opening a hydraulic control operating handle 3 of the lifting oil cylinder, delivering liquid in the hydraulic pump through a hydraulic rubber tube, adjusting the height of the lifting oil cylinder 2, and driving the jack auxiliary sleeve device 6 to move up and down through the lifting oil cylinder 2. When the jack 5 and the detached shaft are at the same level and are concentric, the hydraulic pump is controlled by the hydraulic control operating handle 3 of the lifting cylinder to stop delivering oil, so that the height of the lifting cylinder 2 is determined. And selecting a bolt matched with the internal thread of the fabrication hole on the connecting shaft to be disassembled, and installing the bolt into the gap of the rotatable connector 7. The rotary connector 7 is turned and the connection of the rotary connector 7 and the connecting shaft is achieved by screwing bolts into holes of the connecting shaft.
