[0014] As Figures 1 to 2A disassembling and assembling vehicle for a balance cylinder of a hydraulic support, as shown, includes: a chassis 1, a rotating arm 3, a lifting arm 4, a telescopic arm 5, and an adjusting disc 6. Load-carrying wheels for traveling can be provided on the lower side of the chassis 1. An installation groove 2 is formed in the middle of the chassis 1. A set of conveying devices are provided on each side of the installation groove 2. A tray 21 with a balance cylinder 10 is placed on the conveying devices. The rotating arm 3 is rotatably installed in the installation groove 2. The lower end of the lifting arm 4 is rotatably connected to the upper end of the rotating arm 3. A lifting cylinder 7 is connected to the middle of the lifting arm 4. The lower end of the lifting cylinder 7 is hinged to the bottom of the installation groove 2. The lifting cylinder 7 can push the lifting arm 4 to lift upward and retract downward. The telescopic arm 5 is slidably installed in the lifting arm 4 and its telescoping is controlled by a telescopic cylinder 8. An adjusting cylinder 9 is provided at the rear of the telescopic arm 5. The rear end of the adjusting disc 6 is hinged to the front end of the telescopic arm 5. The front end of the adjusting cylinder 9 is hinged to the front end of the adjusting disc 6. The tray 21 can be clamped on the adjusting disc 6.

[0015] It should be noted that when the lifting cylinder 7 drives the lifting arm 4 to retract downward, the lifting arm 4 will be in a horizontal state above the installation groove 2. If both the telescopic cylinder 8 and the adjusting cylinder 9 are in the retracted state, the adjusting disc 6 will also be in a horizontal state above the installation groove 2.

[0016] The conveying device includes a horizontal conveyor belt 11, a vertical conveyor belt 12, and a propulsion cylinder 13. Both the horizontal conveyor belt 11 and the vertical conveyor belt 12 are powered by a motor 16. Three rows of horizontal conveyor belt 11 wheels are horizontally arranged at equal intervals in the middle and on both sides of the chassis 1. The vertical conveyor belt 12 is arranged parallel to the edge of the installation groove 2. The initial position of the adjusting disc 6 is on one side of the vertical conveyor belt 12 and lower than the height of the vertical conveyor belt 12. The tray 21 is placed on two rows of horizontal conveyor belt 11 on one side. The propulsion cylinder 13 is arranged on the chassis 1 between two rows of horizontal conveyor belt 11 on the other side and is connected and fixed by two fixing plates 14. A connecting rod 17 parallel to the propulsion cylinder 13 is also provided between the two fixing plates 14. A push plate 15 is provided at the front end of the propulsion cylinder 13. The tray 21 can be directly transported from the horizontal conveyor belt 11 to the vertical conveyor belt 12. The vertical conveyor belt 12 can transport the tray 21 to the front of the push plate 15. The push plate 15 can push the tray 21 to directly above the installation groove 2.

[0017] Front baffles 18 and rear baffles 19 are respectively provided at both ends of the adjusting disc 6. The tray 21 is clamped between the front baffle 18 and the rear baffle 19. Fixing bolts 20 are also provided on both sides of the tray 21. Threaded holes matching the fixing bolts 20 are provided on the adjusting disc 6. When the tray 21 is clamped on the adjusting disc 6, the tray 21 can be fixed on the adjusting disc 6 by screwing the fixing bolts 20 into the threaded holes.

[0018] The working process of this device is as follows:

[0019] When installing the balance oil cylinder 10, the lifting arm 4, the telescopic arm 5 and the adjustment disc 6 are all in a horizontal state above the installation groove 2. The pallet 21 provided on the transverse conveyor belt 11 carries the balance oil cylinder 10. The transverse conveyor belt 11 drives the pallet 21 to move onto the vertical conveyor belt 12, and the vertical conveyor belt 12 moves the pallet 21 to the front of the push plate 15 at the front end of the propulsion oil cylinder 13. When the propulsion oil cylinder 13 is started, the push plate 15 will push the pallet 21 onto the adjustment disc 6. Then the lifting oil cylinder 7 is started to lift the pallet 21, and according to the specific installation position, the telescopic oil cylinder 8 is started in sequence to lift the pallet 21 into place. Subsequently, according to the position of the installation point, the adjustment oil cylinder 9 is started to slowly align the balance oil cylinder 10 with the installation hole, and then it is installed and fixed.

[0020] When disassembling the balance oil cylinder 10, first remove the balance oil cylinder 10 and place and fix it on the adjustment disc 6 with the pallet 21. The adjustment oil cylinder 9, the telescopic oil cylinder 8 and the lifting oil cylinder 7 are retracted in sequence. Finally, the balance oil cylinder 10 is above the installation groove 2. At this time, the propulsion oil cylinder 13 is started, and the push plate 15 pushes the pallet 21 with it onto the vertical conveyor belt 12 on the other side, and then it is transported to the transverse conveyor belt 11 along with the vertical conveyor belt 12. When one side of the transverse conveyor belt 11 is full, it can be placed on the transverse conveyor belt 11 on the other side.

[0021] Embodiment 2

[0022] In this embodiment, the transverse conveyor belt 11 is composed of a plurality of evenly spaced transverse rollers, and the vertical conveyor belt 12 is composed of two columns of evenly spaced vertical rollers. The transverse rollers and the vertical rollers are all chain-driven. The vertical rollers are located below the transverse rollers. The vertical rollers are divided into two sections by the middle transverse roller. Each section of the vertical rollers is driven by an independent motor 16, and the vertical rollers are all installed on the support. The support is a liftable support. When the pallet 21 moves above the vertical rollers, the support rises, the vertical rollers contact the pallet 21, and the pallet 21 passes through the middle transverse roller and moves to the other section of the vertical rollers, and then it is pushed onto the adjustment disc 6 by the propulsion oil cylinder 13.

[0023] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
