Technical Field
The invention relates to detaching device for detaching the bolt which can not be taken out normally because the oil or other liquid enters into the connecting piece in the box body or the machine.
Background
The main shaft on the existing oil press is wrapped by two shells, the shells are fixed at through bolts, the shells are called as main shaft shells for short, the bolt arrangement mode is that the shells are fixed in an up-down single-row mode, oil is used for pressing in the main shaft of the oil press shaft, after long-time work, oil in the main shaft shell is immersed between the bolts and the connected piece, the bolts and the connected piece are slowly solidified, so that the bonding force of the bolts and the connected piece is increased, the bolts on the main shaft shell are detachably connected, the original disassembling method is that after the nuts are disassembled, a hammer is manually used for assisting jacking shafts with the outer diameters smaller than the diameters of the bolts to jack the nuts, the heads of the nuts are hammered to the heads of the bolts, labor is wasted, the bolts are very dangerous, vibration and deviation generated on the bolts or the shells can damage the bolts, and the sealing performance of the shells.
Disclosure of Invention
The invention aims to overcome the defects of a manual bolt dismounting technology and provides bolt hydraulic dismounting devices which are safe, reliable, efficient, labor-saving and convenient to disassemble.
In order to achieve the purpose, the invention adopts the technical scheme that:
hydraulic bolt dismounting device, which comprises an L-shaped main body support, wherein the horizontal plate of the main body support is positioned above a vertical plate, and is characterized in that hydraulic cylinders are fixed on the outer wall of the vertical plate of the main body support, connecting holes are arranged on the vertical plate, screw sleeves are fixed on the inner wall of the vertical plate corresponding to the connecting holes, the screw sleeves are used for inserting the screw rods of the bolts to be dismounted, and the push rods of the hydraulic cylinders arranged along the horizontal direction can pass through the connecting holes and enter the screw sleeves;
a right-angle groove is formed in the outer wall of the horizontal plate supported by the main body and faces towards the inside of the horizontal plate, a threaded hole is formed in the vertical side wall of the right-angle groove and faces towards the inside of the horizontal plate, the axis of the threaded hole is arranged along the horizontal direction, spring rods are fixed at the corner of the right-angle groove above the threaded connecting hole along the horizontal direction, springs are sleeved on the spring rods, the inner side rod section of guide rods arranged along the horizontal direction sequentially penetrates through a locking nut and an opening in the upper portion of a clamping plate arranged along the vertical direction and is in threaded connection with the threaded hole, and the clamping plate is tightly pressed with the outer end of each spring rod through the locking nut and tightly presses the springs between the clamping plate and the vertical side wall of the right-;
the lower part of the clamping plate is provided with a screw head sleeve, the screw head sleeve is used for mounting the head of a bolt to be disassembled, and the horizontal axes of the screw head sleeve, the screw rod sleeve and the connecting hole are positioned on the same horizontal line of .
The dismounting device has the advantages that the dismounting device is convenient to mount and simple to operate, the size of the dismounting device is small due to the fact that the clamping plate and the main body support are mounted simultaneously, the size of the dismounting device is reduced so as to be suitable for a narrow space, the guide rod enables the screw head sleeve and the screw rod sleeve to clamp the main shaft shell through the pre-tightening of the locking nut on the clamping plate, and the dismounting of the bolt can be finished for times through the hydraulic cylinder.
