Abstract

The utility model relates to continuous miner cutting arms, in particular to a split type box girder cutting arm, which resolves problems that a continuous miner with a heavy front part and a light rear part can not be applied to drilled shafts. The cutting arm with a split type box girder structure is a split structure composed of two symmetrical cutting arm split structures, and each of the cutting arm split structures is a box girder type structure. By utilizing a box girder structure, the split type box girder cutting arm differs from a solid beam structure and resolves the problem that the complete set has a heavy front part and a light rear part due to an overweight cutting arm. By means of the split structure, the continuous miner cutting arm is applicable to drilled shafts and obtains a wider scope of application.

Description

Connect and adopt the machine cutting arm

Technical field

The utility model relates to connecting adopts the machine cutting arm, is specially the split type case beam form cutting arm of a kind of Lian Caiji of being used for.

Background technology

Lian Caiji has outstanding advantage as a kind of speedy drivage equipment, but cutting arm is overweight, causes weighing the back gently before the Lian Caiji; Because cutting arm appearance and size is greater than the cage size, and can't be used for vertical shaft.

The utility model content

The purpose of this utility model is to provide a kind of company to adopt the machine cutting arm, and it is light and can not be used for the problem of vertical shaft solve to connect heavy back before the machine of adopting.

The technical solution of the utility model is:

The machine cutting arm is adopted by a kind of company, and this cutting arm adopts the case beam type to divide body structure.

The machine cutting arm is adopted by described company, and this cutting arm is symmetrically arranged minute body structures of two cutting arm splits.

The machine cutting arm is adopted by described company, and the cutting arm split is the case girder structure.

The machine cutting arm is adopted by described company, connects by matching used guide, screw, lock washer, nut between the cutting arm split.

The beneficial effects of the utility model are:

1, the utility model cutting arm is different from the entity girder construction by adopting box-beam structure, and it is overweight and make heavy afterwards light problem before the complete machine to have solved cutting arm.

2, the utility model makes it can be used for vertical shaft by dividing body structure, and applicable surface is wider.

Description of drawings

Fig. 1-Fig. 2 is the utility model overall structure figure; Wherein, Fig. 1 is a front view; Fig. 2 is a vertical view.

Fig. 3 is the partial enlarged drawing of coupling part among Fig. 2.

Fig. 4-Fig. 5 is the utility model split structure chart; Wherein, Fig. 4 is a front view; Fig. 5 is a vertical view.

Among the figure, 1 cutting arm split I; 2 cutting arm split II; 3 guidees; 4 screws; 5 lock washers; 6 nuts.

The specific embodiment

As Fig. 1-shown in Figure 2, the utility model connects to be adopted the machine cutting arm and adopts the case beam type to divide body structure, and cutting arm split I 1 and cutting arm split II 2 are symmetrical arranged, and connect by matching used guide 3, screw 4, lock washer 5, nut 6 between the two.

As shown in Figure 3, constitute the coupling part that connects cutting arm split I 1 and cutting arm split II 2 by guide 3, screw 4, lock washer 5, nut 6 supporting uses, guide 3 is plugged in the hole of cutting arm split I 1 and cutting arm split II 2 corresponding settings, plug screw 4 in guide 3, screw 4 external parts are installed lock washer 5 and nut 6 successively.The utility model is realized being connected and fixed of cutting arm split I 1 and cutting arm split II 2 by locking nut 6.

As Fig. 4-shown in Figure 5, the utility model cutting arm split I 1 and cutting arm split II 2 all adopt the case girder structure.

The split of the utility model cutting arm is to obtain by the finite element analysis optimal design, by finite element analysis, obtain stress envelope and distortion distribution map, local targetedly the reinforcement reaches the purpose that reduces local excessive stresses with control local distortion, thereby obtains the rational box-beam structure that distributes.
