When the through hole on only one side ear is a gland mounting hole, the side ear is a side ear close to the old pond.

In the embodiment shown in the drawing, the front ear part and the rear ear part of the guide slipper body are respectively provided with a gland.

When the traditional guide sliding boots are installed, the front ear parts and the rear ear parts of the guide sliding boots are respectively attached to the inner sides of the front side wall and the rear side wall of the walking box shell, two ends of the connecting shaft 2 are fixed on the walking box shell, and through holes in the front ear parts and the rear ear parts of the guide sliding boots are directly contacted with the connecting shaft and can rotate relative to the connecting shaft.

When the guide shoe of the present invention is mounted on the traveling box housing, as shown in fig. 1, the front and rear ear portions thereof are fitted over the front and rear outer side surfaces of the traveling box housing 1 from the bottom to the top, that is, the guide shoe is wrapped around the traveling box housing. The two ends of the connecting shaft 2 and the guide sliding shoes do not rotate relatively, and the connecting shaft 2 can rotate relative to the walking box shell under the drive of the guide sliding shoes. Not only will hold walking wheel subassembly 5 between the ear around the direction boots, still hold the direction boots installation department of walking case casing lower part, therefore the span is great around. The connecting shaft horizontally penetrates through the walking box shell and the guide sliding shoes, and the walking wheel assemblies are coaxially mounted on the connecting shaft and located in the cavities of the walking box shell.

Therefore, the guide sliding shoes are more convenient and faster to mount and dismount relative to the walking box shell, the working strength of mounting and dismounting the guide sliding shoes by operators can be obviously reduced, the working efficiency is improved, and the starting rate of the coal mining machine is improved.

The through hole on the gland is preferably a non-circular hole so that the gland can drive the connecting shaft to synchronously rotate, and the through hole on the gland is preferably a waist-shaped hole in the embodiment. In the initial installation state, the hole walls of the upper and lower parallel planes of the waist-shaped hole are in horizontal positions.

During installation, the guide sliding shoes, the walking box shell and the walking wheel assembly are assembled together through the connecting shafts, and finally the pressing covers are arranged between the connecting shafts and the lug parts of the guide sliding shoe body and fixed on the guide sliding shoe body. To realize the sleeve connection between the gland and the guide shoe body, other structural forms than the stepped shaft hole fit are not excluded, and for example, the fit of a conical surface and a cylindrical surface can also be adopted.

The gland can be fixed with the ear part on the corresponding side of the guide slipper body by adopting various existing modes. The embodiment shown in the attached drawings is fixed by uniformly distributing a plurality of screws 6 on the end surface of the outer side of the gland in the circumferential direction, and the screws 6 are used for providing enough coupling force to ensure that the gland is reliably connected with the guide slipper body. When the connecting shaft is disassembled, the gland 3 and the guide sliding shoe body 4 can be separated only by disassembling the screw 6, and the axial constraint on the connecting shaft is relieved. Because the connecting shaft and the walking box shell are always kept in a relative rotation state during normal work, namely a certain gap is reserved between the connecting shaft and the walking box shell, the connecting shaft can be pulled out by applying a certain pulling force from the old pond side, so that the guide sliding shoe and the walking wheel component are separated from the connecting shaft, the guide sliding shoe and the walking wheel component are conveniently detached, and the labor intensity of underground operators is greatly saved.

The guide sliding shoe body can be an integral casting structural part or a forge welding structural part, when the guide sliding shoe body is a forge welding structural part, the guide sliding shoe body can comprise a front plate c, a rear plate a and a connecting shaft b, the front plate and the rear plate are fixedly connected through penetrating through the connecting shaft, and the front ear part and the rear ear part of the guide sliding shoe body are respectively positioned on the upper parts of the front plate and the rear plate.
