Description
Technical field
The small-sized haulage vehicle that the utility model is related to be used in digging laneway is a kind of Pneumatic crawler specifically
Small-sized haulage vehicle.
Background technology
90% or so of coal in China yield uses pit mining, it is necessary to tunnel a large amount of tunnels, therefore tunnelling safety,
The raising of efficiency for ensuring that exploiting field is taken over, realizes that the safety and high efficiency of coal is of great significance.Colliery full-mechanized roadway with
And working face demand substantial amounts of assistant conveyance work nearby of meeting head on provides guarantee to tunnel, such as fully-mechanized digging machine parts electromechanics is set
Standby, support apparatus, support material etc. by rear portion, it is necessary to be transported near boring head.The mine of rail transport, track are installed
Driving face cannot generally be closely followed.Meanwhile in the especially light-gauge crossheading of digging laneway Belt transport equipment etc. arrangement
Space is occupied, limits the use of large-scale mechanization auxiliary conveying equipments.Monorail crane assistant conveyance is many superior due to its
Property receive welcome, however the serial less important work such as track installation is needed during practice, therefore need to possess comparable condition, and
Its track hangs on top plate, and therefore, it is difficult to be suitable for the tunnel of some rock crushers.And monorail crane transport is only capable of material collection
In transport to designated position, but still have a certain distance apart from working face.Diesel engine railless free-wheeled vehicle cost is higher, and to underground
Ventilation condition is more demanding.The transporting equipment of electric drive frequently overlapped there is cable in long-distance transportation and cable from
The security risk that body damage is brought.It is based on more than reason, the modes such as " drawing land boat " are still in the assistant conveyance of current digging laneway
In the presence of mechanization degree is low, labor intensity is big, efficiency is low, security is poor, the problem especially when carrying out operation on ramp
It is more obvious, adverse effect is brought to the safe efficient production in colliery.
Coal mine underground tunneling roadway assistant conveyance, which sums up, at present has the following problems：
1. generally existing human assistance means of transportation, mechanization degree is low, and labor intensity is big；

Specific embodiment
Referring to the small-sized haulage vehicle of digging laneway Pneumatic crawler shown in Fig. 1,2, driven including chassis, with running motor 3
Crawler unit 4, wagon box 2, dynamical system 7, boom hoisting 1, set chassis on fuel tank 8.
Referring to described in Fig. 3, for the small-sized haulage vehicle using underground pressure air as initial driving force source, pressure wind drives air motor 7
It rotating, air motor 7 exports appropriate rotating speed by 8 speed governing of speed reducer, and double-united oil pump 12 is then driven to generate pressure oil, and then
By pressure oil each executive component is driven to act, such as（Running motor 3 is driven to drive the advance of crawler unit 4, retreat and turn
It is curved；Angling cylinder is driven to drive revolving support, lifting column etc., and compared with 360 ° of rotations of wagon box, driving overturning oil cylinder passes through principal arm
Lift by crane object etc.）.
Air motor 9, the air motor that dynamical system 7 includes using underground pressure air as initial driving force source pass through speed reducer 10
It is connected with the input shaft of double-united oil pump 12.
Referring to Fig. 5, the larger oil pump of fuel delivery passes through the first working hole of pilot operated directional control valve 21, second in double-united oil pump 12
Working hole is connected with the oil inlet of the running motor 3 with mechanical parking structure, and the 3rd working hole of pilot operated directional control valve 21 leads to
It crosses oil cylinder switching valve 19 with overturning oil cylinder 15 to be connected so that running motor and overturning oil cylinder cannot work at the same time.Double-united oil pump 12
The middle smaller oil pump 23 of fuel delivery is connected by speed switching valve 25 with the switching hydraulic fluid port C of running motor.Two oil pumps it is fuel-displaced
Mouth overflow valve 24 in parallel.
Referring to Fig. 4, boom hoisting 1 includes being arranged under wagon box one end, drive in angling cylinder to be turned compared with wagon box
Dynamic revolving support 13 sets the lifting column 14 on revolving support, compared with lifting column under the drive of overturning oil cylinder 15
The outer square set 16 of the principal arm of swing, square set 17 in the principal arm moved axially compared with square set outside principal arm.Boom hoisting is the small-sized fortune
The important component of vehicle is removed, the lifting of material can be realized, and material is loaded to wagon box.The operation principle of boom hoisting：
By operating hydraulic control panel, overturning oil cylinder 15 can be given to provide the action that hydraulic oil realizes lifting up and down；Revolving support can be realized
360 ° of both forward and reverse directions rotations；According to the distance of material position, square set is stretched compared with square set outside principal arm in manually adjustable principal arm
The lifting of different position material is realized in contracting.By more than combination of actions, the material of different position can be sling, and be loaded into vehicle
In bucket, entire hoisting function is realized.
2 surrounding of wagon box is dismountable baffle, can to the materials of the different shapes such as bulk cargo, liquid, structural member and shape into
Luggage is unloaded and transported.
Support hook 5 is both provided in the rear and front end on chassis.Support hook 5, partly cannot be in 2 wagon boxes in the front and back end on chassis
On the larger equipment of the volume transported, can hang on support hook 5, be drawn, various forms of transports are realized with this.
By running motor 3 bilateral crawler unit 4 is driven to walk, crawler unit 4 does not have climbing capacity by force not
The characteristics of skidding, the road surface of the more mud of more water is can adapt to, walking is reliable and stable.
The small-sized haulage vehicle has rational hydraulic system, and the coordination of an executive component can be achieved by the control of hydraulic system
Operation ensures the stability and security of equipment operation.Hydraulic system principle figure is as shown in Figure 5.
Running motor 3 has mechanical halting mechanism, and pilot operated directional control valve 21 at right position, open in running motor 3 by parking spring,
Running motor normal rotation；When pilot operated directional control valve 21 automatically resets to middle position, fuel cut-off in running motor 3, parking spring
Automatic Rapid reset realizes the fast and effective mechanical parking to motor.When pilot operated directional control valve 21 automatically resets to middle position, walk horse
Up to 3 without fuel feeding, be stopped, at this time operating cyloinder reversal valve 19 to left position and right position, it can be achieved that overturning oil cylinder 15 it is flexible,
And then complete lifting of the boom hoisting to material.The design of oil cylinder switching valve 19 can make walking and two processes of lifting only mutually
It is vertical, it is non-interference, it will not work at the same time, avoid the generation of security incident.
Running motor 3, which has, realizes fast switching hydraulic fluid port C at a slow speed, the hydraulic pressure for the smaller oil pump 23 of flow in double-united oil pump
Hydraulic oil can be supplied running motor 3 by switching hydraulic fluid port C, realize running motor row by oil by the switching of speed switching valve 25
The switching of amount, and then can realize that small-sized haulage garage walks fast switches at a slow speed.
It is automatic to unload when overflow valve 24- in hydraulic system ensures equipment operating overload, prevent occurring during lifting
It carries and security incident occurs.
