The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain
As shown in Figure 1; The high-pressure abradant jet current joint-cutting creeps into integrated coal seam drilling machine and is made up of running gear 1, power source 2, hydraulic control system 3; One power source 2 is set on its running gear 1, and the end of power source is provided with a hydraulic control system 3, and the other end of its hydraulic control system 3 connects a bracing or strutting arrangement 4; Bracing or strutting arrangement 4 tops are provided with a principal arm 5, and the end of principal arm 5 connects a rig and water jet system 6.
(1) body
Body is the immobilizing foundation and the load carrier of other each several parts, and every other part is linked as a whole.Body need have enough intensity, rigidity and stability.Former development machine has some tangible advantages in the body design, as hydraulic oil container and body are combined together, the hydraulic oil container steel plate is thickeied the double as frame, has effectively reduced the appearance and size of complete machine, has strengthened the area of dissipation of fuel tank simultaneously.
This machine is transformed and is designed on the basis of former development machine, and former organism provides convenience on the one hand, has shortened the design cycle; Also brought the restriction in some designs on the other hand, new design must be considered the characteristics of former organism.
Further improvement and typing can consider to design again body later on, so that realize the complete machine optimization in Properties
(2) power source
Former development machine whole machine using hydraulic driving mode provides the energy for each action tank or motor by driven by motor hydraulic pump pressure oil output.It is big that hydraulic driving mode has a power-mass ratio, compact conformation, and characteristics such as flexible arrangement, control are convenient also are the first-selected design schemes of various powerful devices under the coal mine.
According to newly added equipment and existing retaining device the demand of driving power is calculated, existing hydraulic power unit can satisfy power demand fully, does not need to increase separately motor and hydraulic pump.This is a very favorable condition, because on the design Selection of power source, not only practiced thrift cost, and has practiced thrift valuable space, and this makes enough flexibilities that has been furnished with of follow-up rig and slot device.
(3) hydraulic control system
The control work of cutterhead when the core of original hydraulic control system is driving; And transform as bore cut all-in-one after; The control changes of function is very big; Increased the mechanism such as rotating hydraulic cylinder of supporting mechanism, rig, position, hole parameter adjustment mechanism and particular design and the control requirement of device, the designs such as layout of original hydraulic control system simultaneously also differ bigger with the requirement of new equipment.So, original hydraulic control system remove basically need not, cooperate the action of big arm, rig and position, hole parameter adjustment mechanism, design the hydraulic control system loop again, again the installation site of control system zero parts etc. is designed for uniformity planning.
(4) running gear
The running gear that former development machine adopts is the bilateral crawler type of drive; The employing low speed hydraulic motor drives; Similar with common bulldozer; Having plurality of advantages such as grounding pressure is low, strong adhesion, driving force is big, ground compliance is strong, can adapt to the coal mine operation environment preferably, is the first-selected type of drive of this kind equipment.
In view of above characteristics, still keep the running gear part of former development machine, can satisfy walking and movement requirement so on the one hand fully, can reduce cost again.
(5) bracing or strutting arrangement
Original light-duty development machine does not have bracing or strutting arrangement, according to the visiting of shop floor worker, can occur complete machine in the work and retreat, and complete machine instability problem such as is lifted by reaction force.So, for designing, it has installed the quadruplet bracing or strutting arrangement additional, be distributed in the car load front and rear, be similar to four bracing or strutting arrangements of hydraulic mobile crane, and strengthened Area of bearing.Can effectively increase the support force of horizontal direction, avoid car load to retreat, simultaneously, owing to strengthened Area of bearing, the stability of car load when effectively having improved work.It is worthy of note that the regeneration product of this type development machine has also increased similar supporting mechanism.
(6) principal arm
Comparatively reasonable as the design of the principal arm of the former development machine that cooperates with cutterhead, but as previously mentioned, as still keeping former principal arm, its with the rig tool between cooperate and be difficult to coordination.Reason mainly is: at first, rig is difficult to realize that the used hydraulic motor rotating speed of former cutterhead is higher around the action that swings of principal arm axis, the low cruise difficulty; Secondly, former principal arm design size rigidity when rig is holed is not enough.Therefore, remove former principal arm, design principal arm again, increase stiffness, simultaneously, install the low speed oscillating motor of particular design additional in principal arm inside, the adjustment of position, hole parameter and the stability of complete machine during with assurance boring, the success rate of assurance boring, slot.
(7) rig and abradant jet system
Appearance and size control during for the work of realization complete machine; Rig should carry out supporting cases of otherwise standard design; But consider the complexity of hydraulic drill rig design and oversize, so this problem selected at present at Zheng's coal down-hole application 150D type all-hydraulic drill of maturation comparatively for use, carried out local flow improvement from the cycle that is designed into trial-production, test; Enable to accomplish simultaneously boring and the work of high-pressure abradant jet current slot, evidence can be satisfied the entire machine design requirement.
(8) data of holes drilled guiding mechanism
Arranging of gas release aperture is the coal seam parameter designing according to when driving tunnelling face place; Change when arranging parameter; Mainly comprise the pore size distribution position; And each hole is with respect to the gradient etc. on driving plane, and the inclination in hole comprises the parameter of horizontal direction angle and vertical direction angle two aspects, and the parameter in each hole is had nothing in common with each other.So the position that will confirm according to the parameter of arranging earlier before the boring and the position of direction adjustment rig so that the hole that gets out can effectively discharge gas, prevent that gas from giving prominence to, and guarantee next step driving safety.Hole guiding mechanism thereby become and bore the core institution cut all-in-one also is the major part of this machine.
According to analysis, boring should comprise two positions and two angle parameters totally 4 parameters, so the pose guiding mechanism of rig should be able to be realized the motion of corresponding 4 degree of freedom.The complete machine of actual design cooperates guiding mechanism can realize the motion of 4 degree of freedom.
