A specification；
The top hold-down devices include suspension column 8, crossbeam 9, rotation handle 10, driver plate 11, big wire role 12, the second spiral shell
Nail 13, locking nut 14, upper fixed seat 15, lower fixed seat 16 form.The upper fixed seat 15 is as top hold-down devices
Body element, other parts are all direct or indirect to be installed in upper fixed seat 15, is in cross after the crossbeam 9 assembling
In the cross bath being equipped with installed in upper fixed seat 15, and upper fixed seat 15 is fixed on by 16 and second screw 13 of lower fixed seat
It is interior, suspension column 8 is designed with each crossbeam 9, each suspension column 8 can be free to slide along 9 direction of crossbeam, realizes adjustable
Function, so as to be adapted to the stretcher of different size specification, described 12 one end of big wire role is connected with 11 interference of driver plate, and one end is set
There are screw thread and the bushing of base support means 17 to be threaded, rotation handle 10 is installed in the pulling hole that driver plate 11 is equipped with.Work
As when stir rotation handle 10 drive driver plate 11 rotate, driver plate 11 drive big wire role 12 rotate, due to big wire role 12 with
The bushing 17 of base support means is in thread fitting, therefore realizes and do vertical up-or-down movement when big wire role 12 rotates, so as to fulfill big
Screw 12 drives top hold-down devices to do overall vertical up-or-down movement.
Hydraulic cylinder maintenance operation schematic diagram according to Fig. 2-3, is described in detail the default function of the present invention.
Disassembling function：21 part of cylinder body that press against hydraulic cylinder 19 by the suspension column 8 of top hold-down devices moves downward,
Meanwhile the apical ring 7 of base support means heads on 20 part of piston of hydraulic cylinder 19 and remains stationary as, and forms 20 phase of cylinder body 21 and piston
To movement, so that hydraulic elongator 19 be dismantled.
Specific demounting procedure is as follows：
The first step：Top hold-down devices are removed；
Second step：Carry out moving adjusting to sliding column 5 by rotating minor leading screw 2, and adjust to the hydraulic cylinder to be dismantled
Position needed for 19 specifications；
3rd step：The apical ring 7 needed for corresponding 19 specification of stretcher hydraulic cylinder is taken to be installed on connector 6；
4th step：Hydraulic cylinder 19 is installed on apical ring 7, and installation method is the bottom that apical ring 7 withstands 20 part of piston.
5th step：Install subordinate's pressure device.First, big wire role 12 is subjected to screw thread company through hydraulic cylinder 9 with bushing 17
Connect；Then, position of the suspension column 8 on crossbeam is adjusted, and each slip column 8 is fully pressed against to the top position of cylinder body 21
Put.
6th step：12 rotary motion of big wire role is driven by stirring rotation handle 10, big wire role 12 drives entirely upper subordinate
Pressure device moves downward, and 21 part of cylinder body that top hold-down devices press against hydraulic cylinder 9 by hanging column 8 moves downward, meanwhile,
20 part of piston that the apical ring 7 of base support means heads on hydraulic cylinder 19 remains stationary as, and forms cylinder body 21 and the opposite fortune of piston 20
It is dynamic, so as to fulfill 9 disassembling function of hydraulic cylinder.
7th step：Maintenance and repair.
Installation function：20 part of piston that press against hydraulic cylinder 19 by the suspension column 8 of top hold-down devices moves downward,
Meanwhile the apical ring 7 of base support means heads on 21 part of cylinder body of hydraulic cylinder 19 and remains stationary as, so that piston 20 is pressed into cylinder body
Installation is completed in 21.
The step of the step of hydraulic cylinder installation process and disassembly process, is basically identical, and the main distinction is the 4th step：Installation
Method is the bottom that 21 part of cylinder body is withstood in the upside of apical ring 7.5th step：Each slip column 8 is evenly distributed on piston 20
Apical position.
In short, mounting and dismounting, difference lies in apical ring 7 during installation to withstand cylinder body 21, and suspension column 8 pushes down piston 20
Move downward；And be that apical ring 7 withstands piston 20 when dismantling, suspension column 8 is pushed down cylinder body 21 and is moved downward.
Embodiment 2
As shown in figure 4, this hydraulic cylinder maintenance unit is Pneumatic power elevator apparatus.With the hydraulic cylinder maintenance unit knot of embodiment 1
Structure and principle are basically identical, its main distinction is that driving top hold-down devices to rise overally by pneumatic linear actuator 22 declines fortune
