Description
Technical field
This utility model is related to technical field of engineering machinery, and in particular to rotary drilling rig crawler belt automatic plug pin shaft device.
Background technology
Rotary drilling rig is a kind of construction machinery of pore-forming operation in suitable building foundation engineering.It is primarily adapted for use in sand, sticks
Property the soil layer construction such as soil, slity soil, extensively should obtain in various foundation basic constructions such as bored concrete pile, diaphragm wall, strengthening of foundation
With.Spiral digging machine pore-forming is to make drilling tool be rapidly reached stake position by the own walking function of rig and mast jib lubbing mechanism first, profit
Lowering drill pipes being oriented to mast and hosqe bit of the bottom with valve being placed to into hole position, drill power head device is provided for drilling rod
Plus-pressure is passed to drilling rod, drill bit by moment of torsion, pressue device by way of the unit head that pressurizes, and bit convolution crushes ground, and
Directly it is loaded in drill bit, then by rig lifting device and telescopic drill rod proposes to unload soil outside hole by drill bit again, so follows
Ring is reciprocal, constantly fetches earth, unloads soil, until getting into design hole depth.
Used as crawler type rotary drilling rig, crawler belt is one of key fitment of base plate of rotary drill rig, because rotary drilling rig is being carried out
During band extension or contraction, staff is needed to get into the pin plugged under base plate of rotary drill rig for fixing two side legs
Axle, there is very big danger in this.At present, all it is to get into inserted below borer chassis by staff on domestic rotary drilling rig
Pull pin axle, although the number of times of plug bearing pin is not very frequently, but to get into and plug bearing pin not below operating base plate of rotary drill rig
Labor intensity is only increased, and the life security to staff constitutes very big threat, and job site place ring
Border is possible to very severe, and also inconvenient staff goes down to underbody, meanwhile, the jack of bearing pin is also not easy to upper, therefore, people
Work plug bearing pin is not only troublesome but also loses time, also danger close.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of novel, reasonable in design of proposition,
It is simple operation, safe and reliable, can be replaced manually plugging bearing pin with automatic control system when crawler belt is flexible, solve and manually plug
Dangerous, inefficiency that bearing pin is present, the rotary drilling rig crawler belt automatic plug pin shaft device of the problem that wastes time and energy.
This utility model rotary drilling rig crawler belt automatic plug pin shaft device, including crawler rack, the device includes being arranged on
In rotary drilling rig frame dismountable electric pushrod mounting bracket and moveable electricity is arranged in electric pushrod mounting bracket
Dynamic push rod, arranges connecting plate on crawler rack, and in the connecting plate both sides of crawler rack limit switch is respectively provided with.Stretched in crawler belt
Cheng Zhong, when electric pushrod position reaches the position of limit switch, then trigger switch action, so as to control electric pushrod fortune
It is dynamic, insert or pull out bearing pin.
Described electric pushrod is arranged on electric pushrod mounting bracket side just to bearing pin direction.
The beneficial effect of this utility model rotary drilling rig crawler belt automatic plug pin shaft device：
1) in rotary drilling rig frame dismountable electric pushrod mounting bracket and be arranged on electric pushrod installation
Moveable electric pushrod, arranges connecting plate on crawler rack on support, is respectively provided with the connecting plate both sides of crawler rack spacing
Switch, in crawler belt telescopic process, when electric pushrod position reaches the position of limit switch, then trigger switch action,
So as to control electric pushrod motion, insert or pull out bearing pin, relatively manually got in the past artificial plug bearing pin safety below chassis,
It is time saving and energy saving, finally improve work efficiency；
2) novel, reasonable in design, simple operation, safe and reliable, when crawler belt is flexible, available automatically controlling is
System replaces artificial plug bearing pin, solves dangerous, inefficiency that artificial plug bearing pin is present, and waste time and energy problem.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state figure of the present utility model.
In figure：1st, electric pushrod, 2, electric pushrod mounting bracket, 3, rotary drilling rig frame, 4, bearing pin, 5, crawler rack,
6th, limit switch, 7, connecting plate.
Specific embodiment
Below with reference to accompanying drawing, the utility model is described in further detail.
The specific structure of this utility model is：Including crawler rack 5, the device includes being arranged in rotary drilling rig frame 3
Electric pushrod 1 and be arranged in electric pushrod mounting bracket 2 moveable electric pushrod 1, on crawler rack 5 arrange
Connecting plate 7, in the both sides of connecting plate 7 of crawler rack 5 limit switch 6 is respectively provided with.The electric pushrod 1 is arranged on electric pushrod 1 pacifies
Dress support side is just to the direction of bearing pin 4.
Can drive external crawler rack 5 along the length direction displacement of track beam by extending the flexible of oil cylinder, enter to exercise it is left,
Distance between right external crawler rack 5 is realized extension or is shunk, and is the break-make that electromagnetic valve is controlled by handle, then by electromagnetic valve
Control crawler belt telescopic oil cylinder it is flexible realizing, therefore handle is used as the main switch of automatic plug pin shaft device, by spacing
Signal of the switch 7 as the action of electric pushrod 1.During extended distance between left and right external crawler rack 5, operation handle action
When, automatic plug pin shaft device obtains electric, the action of electric pushrod 1, extracts bearing pin 4, because this device is using with built-in spacing
The electric pushrod 1 of switch 6, so electric pushrod 1 will be automatically stopped action after bearing pin 4 is extracted completely, while stretching to control
The solenoid signal of contracting oil cylinder, makes oil cylinder start to stretch, when crawler belt expands to target location, electric pushrod mounting bracket 2
The position of limit switch 6 is just moved to, while triggering the action of limit switch 6, flexible oil is controlled when 6 action of limit switch
The electromagnetic valve and electric pushrod 1 of cylinder obtains signal simultaneously, and electromagnetism valve events make oil cylinder stop motion, the action of electric pushrod 1, by pin
Axle 4 is inserted, same because electric pushrod has built-in limit switch 6, and after bearing pin 4 is fully-inserted action will be automatically stopped.Left,
It is identical with the operating principle during extension when distance between right external crawler rack 5 is shunk.
