Abstract
The utility model discloses an auxiliary climbing device of a large-gradient tunneling machine. The auxiliary climbing device comprises a supporting device which is arranged on the tail portion of the tunneling machine, the supporting device comprises a top plate, a supporting oil cylinder and a base, the supporting oil cylinder is arranged between the top plate and the base, and the base is connected with two gantries of the tunneling machine through a thrust oil cylinder. The auxiliary climbing device can push the tunneling machine to advance in a large-gradient tunnel and can prevent the tunneling machine from sliding down under the effect of gravity of the tunneling machine during working of the tunneling machine.
Description
Technical field
The utility model relates to a kind of coal mine machinery, especially a kind of device of auxiliary development machine climbing.
Background technology
Development machine is one of conventional machinery in the present coal mining activity, and existing development machine generally includes fuselage, be arranged on cutting arm that fuselage head is used for excavating, be arranged on the two fortune framves that afterbody is used for the transhipment material.The driving that utilizes development machine to carry out work plane is a kind of easy to operate, safe tunneling method.Yet, when the gradient of coal mine roadway is larger, be difficult to make existing development machine to arrive smoothly work plane, namely allow to arrive, also be difficult to guarantee the stability of its operation, therefore, for the excavation operation of heavy grade, the mode that usually changes the big gun pick into is carried out.The shortcoming that the dangerous property of big gun pick technology is high, operation easier is large.
Therefore, how making development machine arrive smoothly work plane is the technical barrier that needs at present solution.
The utility model content
The utility model technical issues that need to address provide the auxiliary climbing apparatus of a kind of large gradient roadheader, can improve climbing capacity and the operation stability of development machine.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Large gradient roadheader is assisted climbing apparatus, comprise the bracing or strutting arrangement that is arranged on the development machine afterbody, described bracing or strutting arrangement comprises top board, support cylinder, base, and described support cylinder is arranged between top board and the base, and base is connected with the two fortune framves at development machine rear portion by propelling cylinder.
Improvement of the present utility model is: described bracing or strutting arrangement is two groups, be respectively bracing or strutting arrangement I and bracing or strutting arrangement II, described bracing or strutting arrangement I and bracing or strutting arrangement II are successively set on the development machine afterbody, be connected with the bracing or strutting arrangement II on the base of bracing or strutting arrangement I and all be symmetrically arranged with two propelling cylinders that are connected with the two fortune framves at development machine rear portion respectively that are positioned at chassis outer side on the base, the base of bracing or strutting arrangement I is between two propelling cylinders of bracing or strutting arrangement II.
Further improvement of the utility model is: the top board below is symmetrical arranged two support cylinders.
Owing to having adopted technique scheme, the obtained technological progress of the utility model is:
The utility model is simple in structure, and flexible operation, effect stability can improve the climbing capacity of development machine in the heavy grade tunnel and the stability in when operation, have advantages of efficient, safe.Bracing or strutting arrangement of the present utility model utilizes support cylinder that top board and base are expanded round about, thereby is supported in the tunnel securely, and as fulcrum, utilizes propelling cylinder to promote development machine and push ahead along the tunnel.After once propelling was finished, bracing or strutting arrangement shrank, and close to development machine, changed position of the fulcrum, carried out expansion and the propelling of next round.When development machine carries out excavation operation, bracing or strutting arrangement is fixed in the tunnel, can plays a supporting role to development machine, avoid it to glide along the tunnel because of gravity and reaction force.
When two groups of bracing or strutting arrangements being set can preventing that bracing or strutting arrangement from shrinking, development machine since Action of Gravity Field glide along the tunnel, thereby make development machine can adapt to the larger tunnel of the gradient.Two support cylinders are set, make the bracing or strutting arrangement can be according to the concavo-convex situation of tunnel inwall, flexible modulation pressure makes support more firm.

Fig. 2 is the schematic top plan view of Fig. 1;
Wherein: 1, development machine, 2, two fortune framves, 3, propelling cylinder, 4, support cylinder, 5, top board, 6, base.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
As shown in Figure 1, 2, large gradient roadheader of the present utility model is assisted climbing apparatus, comprise two groups of bracing or strutting arrangements that are arranged on development machine 1 afterbody, this bracing or strutting arrangement comprises top board 5, support cylinder 4, base 6, be symmetrically arranged with two support cylinders between top board and the base, the base both sides respectively arrange a propelling cylinder 3 and are connected with the two fortune framves 2 at development machine rear portion, and the bracing or strutting arrangement of close development machine is the bracing or strutting arrangement I, and another is the bracing or strutting arrangement II.The base of bracing or strutting arrangement I is between two propelling cylinders of bracing or strutting arrangement II.When needing climbing, support cylinder is expanded top board and base round about, thereby is supported in the tunnel securely, and as fulcrum, utilizes propelling cylinder to promote development machine and push ahead along the heavy grade tunnel.After once propelling was finished, bracing or strutting arrangement shrank, and close to development machine, changed position of the fulcrum, carried out expansion and the propelling of next round.Bracing or strutting arrangement I and bracing or strutting arrangement II alternate run can avoid development machine to glide along the tunnel because of Action of Gravity Field.During development machine work, two bracing or strutting arrangements are supported in the tunnel simultaneously, and the reaction force in the time of can avoiding development machine because of gravity and driving glides along the tunnel, thereby has ensured its operation stability.
