Abstract
The utility model relates to a jack supporting device for a coal mining drilling rig, which comprises a supporting plate with a convex object and a pressure plate with a ball socket. The supporting plate and the pressure plate are connected to form an integer by a bolt. The supporting plate is of a convex shape, the diameter of the bottom surface is expanded, the diameter of the upper part is reduced, and the supporting plate is provided with a triangular reinforcing plate; the combined surface of the pressure plate and the supporting plate is provided with a cooperation spigot and a gasket, a bolt cap is provided with a bolt protective cap in a matching way, a dustproof ring groove is arranged at the upper opening of the ball socket of the pressure plate, and the dustproof ring groove is provided with a dustproof half ring in the matching way. The jack supporting device for the coal mining drilling rig is mainly used for a jack which fulfills the guiding and supporting actions of the coal mining drilling rig in an unmanned mining working surface in a thin coal seam. The jack supporting device for the coal mining drilling rig has the advantages that the supporting action area is expanded by above 3 times, the weight is lightened by about 1/5 times, the dustproof and the corrosion protection effects are good, the repair and the maintenance are convenient and the regulation of the rotation of the two spherical hinges is flexible.
Description
Technical field
The utility model relates to the jack that the unmanned exploitation of girdle driving surface Coal-mining drilling machine plays guiding and supporting role.
Background technology
At present, the jack that the unmanned exploitation of girdle driving surface Coal-mining drilling machine plays guiding and supporting role all has bracing or strutting arrangement, and its version all adopts the outer-enwraped type that cooperates with ball pivot at the bottom of this jack cylinder to support tray type structure.This supporting disk is split type, comprises the supporting disk of being with protrusion and the platen of dribbling nest, is one-piece construction by bolted connection.In use there is following shortcoming in the bracing or strutting arrangement of this structure: (1) supporting disk active area is little, and when Coal-mining drilling machine was worked, it easily pierced and aggravates to be absorbed in the rib, so that can not work by the firm support rig; (2) ickings is piled up on the platen, causes ball pivot cooperation place corrosion at the bottom of bolt, the jack cylinder and not quick detachable, causes maintenance, changes the supporting disk difficulty.
Summary of the invention
The purpose of this utility model is that existing jack bracing or strutting arrangement is improved, and a kind of rib, in light weight, Coal-mining drilling machine jack bracing or strutting arrangement for ease of maintenaince of not piercing is provided.
The utility model is achieved in that this bracing or strutting arrangement comprises the supporting disk of being with protrusion and the platen of dribbling nest, and supporting disk becomes whole with platen by bolted connection, it is characterized in that, supporting disk is a convex shape, the bottom surface enlarged-diameter, upper diameter is dwindled, and is furnished with the triangle gusset; On platen and the supporting disk faying face seam of cooperation and pad are arranged, be equipped with the bolt head protector on the bolt cap, the place suitable for reading of platen ball-and-socket is provided with dustproof ring recess, the dustproof semi-ring of assembling on the dustproof ring recess.
The utility model has the advantages that: 1, because supporting disk adopts convex shape and stiffened panel structure, and the supporting role enlarged areas is more than 3 times, about 1/5 times of weight saving has greatly improved its support effect; 2, owing to adopt measures such as seam, bolt head protector, dustproof semi-ring, make dustproof, corrosion protection result good, maintenance, easy to maintenance; 3, put into the pad of suitable quantity by assembling, can debug the alerting ability of ball pivot rotation.
Description of drawings
Fig. 1 is the main scheme drawing of looking of analysing and observe of the present utility model.
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the birds-eye view of Fig. 1.
Among the figure: 1-supporting disk, 2-triangle gusset, 3-bolt, 4-pad, 5-bolt head protector, 6-platen, the 7-semi-ring that prevents dust, 8-cooperates seam.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model is made up of the supporting disk 1 of band protrusion and the platen 6 of dribbling nest generally, supporting disk 1 and platen 6 connect into integral body by bolt 3, described supporting disk 1 is a convex shape, its bottom surface enlarged-diameter, upper diameter is dwindled, and is furnished with triangle gusset 2; On the faying face of described platen 6 and supporting disk 1 seam of cooperation 8 and pad 4 are arranged, be equipped with bolt head protector 5 on the bolt cap, the effect of fitting-up bolt head protector 5 is to be used to prevent dust, and the place suitable for reading of platen 6 ball-and-sockets is provided with dustproof ring recess, is equipped with dustproof semi-ring 7 on the dustproof ring recess.
