Abstract
A kind of crawler belt maintenance unit, including oil cylinder, connecting rod and base are the utility model is related to, the oil cylinder and base are relatively fixed installed in connecting rod both ends, with being provided with through hole on the base of the oil cylinder push rod relative position；The utility model beneficial effect is：Creeper tread is placed on base, and bearing pin is ejected by relative hydraulic jack push rod, creeper tread is carried out quick-replaceable maintenance at the scene.
Description
Technical field
It the utility model is related to a kind of maintenance unit, more particularly to a kind of crawler belt maintenance unit.
Background technology
At present, crawler belt in use once break down or damage if need to transport maintenance center back and repaired, no
The quality time of client is only have impact on, and logistics cost is also created in transportation.
Especially bearing pin serious wear is, it is necessary to change, or when wherein one section of chain rail or creeper tread damage need to change,
Being required to specific purpose tool and place could change, in view of the above-mentioned problems, we need, one kind is simple in construction, can realize at the scene
The crawler belt maintenance unit of rapid-maintenance.
Utility model content
The utility model solve technical problem be：The scene inconvenience maintenance such as crawler belt failure or damage maintenance building site produces
The problem of.
The utility model is to solve the technical scheme that is provided of above-mentioned technical problem：
A kind of crawler belt maintenance unit includes oil cylinder, connecting rod and base, and the oil cylinder and base are relatively fixed installed in company
Through hole is provided with extension bar both ends, with the base of the oil cylinder push rod relative position, base effectively fixation aligns crawler belt, passes through oil cylinder
Push rod crawler belt bearing pin is ejected, convenient and swift maintenance.
Also include flange, the flange is fixedly mounted on cylinder wall, and the connecting rod is connected by flange with oil cylinder, method
Orchid is enclosed on oil cylinder, makes cylinder force uniform, effectively protects oil cylinder outer wall.
Preferable also to include positioner, positioner is arranged on base, and the positioner can be quickly by crawler belt
Plate bearing pin is positioned on maintenance unit.
Preferable also to include location-plate, the location-plate installation is on the positioning device, parallel with crawler belt placement, facilitates crawler belt
Plate order keeps flat rapid-maintenance.
Preferable also to include ejector pin, the ejector pin is arranged on oil cylinder push rod by lengthening joint, and ejector pin can be protected effectively
Protect oil cylinder top.
The lengthening joint is more than or equal to 1, effectively reduces oil cylinder lift rod stroke.
The hanger, the hanger are separately mounted on bottom plate and flange, convenient lifting.
The lengthening joint is connected by screw thread or bolt with ejector pin.
The utility model beneficial effect is：Creeper tread is placed on base, by relative hydraulic jack push rod to pin
Axle is ejected, and creeper tread is carried out quick-replaceable maintenance at the scene.
Brief description of the drawings
Fig. 1 is a kind of wheel crawler belt maintenance unit schematic diagram；
Wherein, 1, oil cylinder, 2, flange, 3, hanger, 4, lengthening joint, 5, connecting rod, 6, location-plate, 7, positioner, 8,
Base, 9, ejector pin, 10, through hole.
Embodiment
Referring to the drawings, in the utility model, including the shell mounting flange 2 of oil cylinder 1, flange 2 connect bottom by two connecting rods 5
Seat 8, lengthening joint 4, and two pieces ejector pin 9 are connected on the push rod of oil cylinder 1；Positioner 7 and location-plate 6 are installed on base.
When repairing crawler belt, by vehicle operation device hydraulic oil pipe or external hydraulic oil pump, oil cylinder 1 is connected, will wait to tie up
Repair crawler belt and pass through maintenance unit, be placed between two connecting rods 5, by crawler belt to be repaired by positioner 7 make bearing pin to be removed with
Ejector pin 9 aligns, at the same crawler belt by location-plate 6 ensure position it is constant, start hydraulic system oil cylinder 1 is worked, drive ejector pin 9 to
Preceding movement, bearing pin is ejected；Repeat same step to eject previous section bearing pin, damage component is taken out；, will after being put into new component
New bearing pin is pressed into successively again；So far the replacing of crawler belt damaged location to be repaired is completed.
