Description

Technical Field

[0001] The utility model relates to a labor-saving oil cylinder disassembly device, belonging to the technical field of roller pressing equipment. Background Art

[0002] After the rolling mill was installed, it was found that the installed cylinder was of the wrong model or in the wrong direction. At present, our conventional operation method is to lift out all the two rollers on the cylinder with a crane, and then use the crane to lift the cylinder from the main machine for replacement. This requires a lot of time to lift and install the rollers back and forth. It greatly affects the work efficiency and assembly accuracy. At this time, we need to be able to quickly and labor-savingly remove the main cylinder from the archway without affecting other assemblies, and then replace the replaced cylinder back to quickly solve the disassembly and assembly of this type of main cylinder. Utility Model Content

[0003] In order to solve the problems existing in the background technology, the utility model provides a labor-saving oil cylinder disassembly device, which can pull out the heavy oil cylinder more labor-savingly through single-person operation, and then push it away for replacement.

[0008] Furthermore, sliding beams are provided on both sides of the frame, and the sliding beams and the driving screw are parallel to each other.

[0009] Furthermore, the frame has multiple sets of sliding beam installation positions for adjusting the distance between two sliding beams.

[0010] Furthermore, the reducer is installed on the top of the frame through a reducer base.

[0011] Furthermore, the wheel at the rear bottom of the frame is a universal brake wheel.

[0012] Furthermore, a plurality of grooves are provided on the top of each sliding beam, and the plurality of grooves are arranged along the extension direction of the sliding beam; a roller is provided in each groove, and the top end of the roller is higher than the top surface of the sliding beam.

[0013] Furthermore, a front cross beam is provided at the front end of the sliding beam, and the front cross beam connects the two sliding beams.

[0014] Furthermore, support rods are provided at the bottom of the frame and the bottom of the front cross beam, and support seats threadedly connected to the bottom ends of the support rods are provided at the bottom ends of the support rods.

[0015] Compared with the background technology, the utility model has the following advantages:

[0016] The utility model pulls the oil cylinder onto a roller guide block through the screw drive of the reducer, so that the heavy oil cylinder can be pulled out through sliding, and then moved away and replaced by a trolley, which is more labor-saving and more efficient.

[0017] The roller guide block is installed in the groove of the crossbeam 2 to 3 mm higher than the surface of the crossbeam. There are 5 grooves on each of the left and right crossbeams and 5 roller guide blocks are installed. The distance between the two crossbeams is adjusted by the hole spacing of the fixed screw holes on the trolley. The oil cylinder can slide easily regardless of size. The front support seat is placed on the main machine to support it mainly to prevent the trolley from tipping over due to excessive weight on the head, and the height can be adjusted through the threads of the support rod and the support seat.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-2 The specific implementation methods of the utility model are further described in detail with examples.

[0022] Refer to Figure 1This embodiment includes a frame, and a wheel is provided at the bottom of the frame; a reducer 1 is provided at the top of the frame, and the output shaft of the reducer is connected to one end of a driving screw; a moving seat is also provided on the driving screw and is threadedly connected thereto, and a cylinder fixing bolt 6 is connected to the moving seat, and the cylinder fixing bolt is clearance-matched on the moving seat;

[0023] The distance between the transmission screw and the top of the frame is greater than the thickness of the oil cylinder.

[0024] A through hole is arranged on the movable seat, and the oil cylinder fixing bolt is located in the through hole and can freely move and rotate along the central axis of the through hole.

[0025] Sliding beams are arranged on both sides of the frame, and the sliding beams are parallel to the driving screws; the frame has multiple sets of sliding beam installation positions for adjusting the distance between the two sliding beams.

[0026] The reducer is installed on the top of the frame through the reducer base. The wheel at the rear of the bottom of the frame is a universal brake wheel.

[0027] A plurality of grooves are arranged on the top of each sliding beam, and the plurality of grooves are arranged along the extension direction of the sliding beam; a roller is arranged in each groove, and the top end of the roller is higher than the top surface of the sliding beam.

[0028] The front end of the sliding beam is provided with a front cross beam, and the front cross beam is connected between the two sliding beams. The bottom of the frame and the bottom of the front cross beam are both provided with a support rod, and the bottom end of the support rod is provided with a support seat threadedly connected thereto.

[0029] We use a small cylinder replacement trolley to lift the two roller systems directly upwards with a crane. We then fix the cylinder fixing bolts on the screw holes in the center of the cylinder. The lead screw of the cylinder replacement trolley passes through the round hole above the cylinder fixing bolts. The lead screw of the reducer drives the cylinder to be pulled onto the roller guide block. This way, the heavy cylinder can be pulled out more effortlessly by sliding, and then removed and replaced.

There are 5 grooves on each of the left and right crossbeams and 5 roller guide blocks are installed. The distance between the two crossbeams is adjusted by the hole spacing of the fixed screw holes on the trolley. The oil cylinder can slide easily regardless of size. The front support seat is placed on the main machine to support it mainly to prevent the trolley from tipping over due to excessive weight on the head. The height is adjusted by the threads of the support rod and the support seat.
