When receiving advancement commands, two telescopic outrigger pressure releases of the first walking protective unit being positioned in direction of advance are shunk, with
Time the first protective plate pressure release walking protective unit, depart from and protect dome-shaped state, the first walking protective unit being positioned in direction of advance
Working with two hydraulic cylinders being connected on the second walking protective unit sliding sleeve, it is single that hydraulic cylinder is connected to the first walking protection simultaneously
Hydraulic stem elongation on unit's sliding sleeve, now, the hydraulic mechanism on remaining walking protective unit keeps supporting state, in hydraulic cylinder
Hydraulic stem fully extended after, complete the walking of the first walking protective unit；Then, the walking lower limb of the first walking protective unit adds
Pressure stretch goes out, and protective plate lifts simultaneously, it is achieved supporting；Pack up the second walking protective unit telescopic outrigger, and by the second walking protection
The protective plate pressure release of unit is shunk, and now, is connected to two on the first walking protective unit and the second walking protective unit sliding sleeve
Individual hydraulic stem shrinks, and the second walking protective unit walks two the hydraulic cylinder elongations being connected on protective unit sliding sleeve with the third line,
Push-and-pull second protective unit of walking moves to the first walking protective unit, is repeated in mobile remaining walking protective unit, real
Certainly the walking of existing complete machine；Only need to be using first walking protective unit in reverse direction as the first walking protective unit when falling back
Execution above-mentioned steps.
The invention has the beneficial effects as follows: structure design is simple, automatically walks, highly, length and width all can be at design model
Enclose interior regulation, make and use cost is low, use hydraulic system, safe and convenient to use, setting of some single walking protective units
Putting so that in walking process, protective plate is still provided that protection, the design of double walking beams so that power demand is low, walks more square
Just.
Accompanying drawing explanation
The invention will be further elaborated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure: 1, protective plate, 2, sliding sleeve, 3, crossbeam, 4, telescopic outrigger, 5, walking beam, 6, two-way hydraulic cylinder, 7, sole.
Detailed description of the invention
Embodiment 1
One as shown in Figure 1, from walking development machine protective stent, including some walking protective units, and is connected to several rows
Walk the actuating unit between protective unit；Described walking protective unit includes protective plate 1, two sliding sleeves 2, connects two sliding sleeves
Crossbeam 3, be separately mounted on two sliding sleeves and with two telescopic outriggers 4 of beam vertical, crossbeam 3 and two telescopic outrigger 4 shapes
Becoming door frame shaped structure, protective plate 1 is arranged on sliding sleeve 2 or crossbeam 3, and is positioned at above crossbeam 3；Some walking protective units pass through
Respective two sliding sleeves 2 are socketed on two walking beams 5 one entirety of one-tenth.
Described protective plate 1 is arc, is set to two pieces, and protective plate arc one end is hinged with sliding sleeve, and the other end is unsettled,
Pin joint and unsettled between protection plate body on connect the telescopic arm of hydraulic cylinder, the hydraulic cylinder other end is arranged on crossbeam.
When described protective plate 1 is arc, two boards when protecting top board in the middle of leave gap.
Described actuating unit is made up of hydraulic control device and the hydraulic cylinder being connected with hydraulic control device.
Being mounted on a two-way hydraulic cylinder 6 between the sliding sleeve 2 of two adjacent walking protective units, hydraulic control fills
Putting the elongation by controlling two-way hydraulic cylinder 6 one end or connected sliding sleeve 2 is promoted or tractive by contraction, sliding sleeve 2 drives to be stretched
Contracting supporting leg 4 realizes advancing or retreating.
The bottom of described telescopic outrigger 4 is provided with sole 7, for strengthening the contact area with ground.
Embodiment 2
Difference from Example 1 is, described protective plate 1 is straight plate, arranges two pieces of one piece or symmetry, by being arranged on horizontal stroke
Beam two ends or hydraulic cylinder on two sliding sleeves connect.Straight plate arranges one piece or each one piece of left and right, in view of underworkings chi
During very little change, using symmetrical two pieces, regulation gap is left in centre.
Crossbeam can be telescoping crossbeam, and in down-hole, owing to the width in tunnel is different, therefore, telescoping crossbeam can be adjusted
Save the width adequate tunnel of whole equipment.
As embodiment 1 and the working method of embodiment 2:
The control instruction of described hydraulic control device, from manual cable controller or Digiplex, is receiving advancement commands
Time, two telescopic outrigger pressure releases contractions of the first walking protective unit being positioned in direction of advance, the first walking protection is single simultaneously
The protective plate pressure release of unit, departs from and protects dome-shaped state, and the first walking protective unit and the second walking protection that are positioned in direction of advance are single
Two hydraulic cylinders connected on unit's sliding sleeve work simultaneously, and hydraulic cylinder is connected to the hydraulic stem on the first walking protective unit sliding sleeve
Elongation, now, the hydraulic mechanism on remaining walking protective unit keeps supporting state, and the hydraulic stem in hydraulic cylinder is fully extended
After, complete the walking of the first walking protective unit；Then, the walking lower limb pressurization of the first walking protective unit is stretched out, and protects simultaneously
Plate lifts, it is achieved supporting；Pack up the second walking protective unit telescopic outrigger, and by the protective plate pressure release of the second walking protective unit
Shrinking, now, two hydraulic stems being connected on the first walking protective unit and the second walking protective unit sliding sleeve shrink, and second
Walking protective unit walks two the hydraulic cylinder elongations being connected on protective unit sliding sleeve with the third line, and push-and-pull second is walked and protected list
Unit moves to the first walking protective unit, is repeated in mobile remaining walking protective unit, it is achieved the walking certainly of complete machine；Fall back
Time only need to perform above-mentioned steps using in reverse direction first walking protective unit as the first walking protective unit.
The present invention designs rational in infrastructure, when walking, owing to simply a walking protective unit is changed to put by the state of holding out against
Pine state, remaining protective unit still stress of walking, do not result in pine and push up, and the walking unit after loosening, protective plate is with flexible
Supporting leg all relaxs one's efforts, and no longer exerts a force ground and top, tunnel, therefore, is slided over by Hydraulic Cylinder and easily move on walking beam
Dynamic, rear portion suspension roof support is not had any impact by this movement, and work efficiency is greatly improved；And structure design is simple, from
Dynamic walking, makes and use cost is low, uses hydraulic system, safe and convenient to use, the setting of some single walking protective units,
Making in walking process, protective plate is still provided that protection, the design of double walking beams so that power demand is low, walks more convenient.
Disclosed embodiment of this invention is the explanation to technical scheme, it is impossible to as to present invention
Restriction, those skilled in the art's simple change on the basis of the present invention, the most within the scope of the present invention.
