Abstract

The invention relates to lifting and handling equipment. The purpose of the invention is to improve the performance characteristics by using it for various sizes of rail conductors with one-sided and two-sided arrangement. The guide shoe contains a body of two sections 1, a frontal 2 and side 3 removable liners that interact with the conductor, elastic and fasteners. Each section 1 is made Z-shaped with a groove 9 in the lower part, and the inner surface of its upper flange is beveled at an angle of 4-8 °. Each of the side liners has a beveled edge associated with the top shelf of the section and a cutout on the opposite face. The frontal liner is mounted on an elastic gasket and has protrusions located simultaneously in the neckline of the corresponding side liner and the groove of the body section. In this case, sections of the housing are connected with clamping face plates in contact with the frontal and side inserts. 4 il.

FIG. 1 shows a general view of the shoe; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - L-shaped side inserts.

Directing the clock shoe mine; lifting vessel consists of a body made of two symmetrically located sections - 1, frontal

two side 3 interchangeable liners, an elastic gasket 4, clamping plates: lining 5, bolts 6 and 7, fastening respectively the grip 5 to the sections of the body and the shoe to the vessel, the cushioning sleeves 8 (Fig. 1, 2). Each section has a groove 9 in the lower part, and the inner surface of its upper flange 10 is beveled at an angle of 4-8 ° C with an inclination towards the conductor. The side inserts have beveled edges 11, matching with the inner surface of the shelf 10, and notches 12 on opposite faces. The frontal liner 2 is provided on both sides with protrusions 13, which are located in the notches 12 of the side liners and in the slot 9 of the body section, and is mounted on an elastic gasket 4. For ease of assembly and installation of the shoe there is a base plate 14 located between the shoes and the lifting plate. vessel. The side inserts 3, depending on the layout of the conductors 15 relative to the vessel, are made in the form of rectangular plates or L-shaped with beveled edges on non-working surfaces in contact with the surface of the shelf section of the housing.

The sections are interconnected by means of clamping end plates 5 and bolts 6 (Fig. 2). In addition, the plates, in contact with the ends of the inserts, limit their movement and are held in the housing during operation. Frontal and side inserts are made of cast.

Assembly of the shoe works as follows.

A support housing section 1 is installed on the support plate 14 and secured with bolts 7 without tightening them. Then, one side and frontal plate with rubber gasket 4 is installed and bolts 7 are tightened. Due to the elasticity of the gasket, the contribution ... is maintained between the base plate and the section. After that, install the second section 1 with the side insert 3 and connect it to the base plate 14. Then connect both sections 1 with clamping end plates 5. To replace the insert 2, 3, just release the bolts 7, remove one end plate, remove the old ones insert and install new ones.

When acting on the frontal liners 2, 3 of the shoe of the moving vessel of the dynamic load, the elastic gasket 4 is compressed, and a gap is formed between the beveled surfaces of the side liner 3 and the upper shelf of the body section. In this case, the side insert may tilt towards the conductor 15 and get out of engagement with the body section. When the elastic thickness is 5-10 mm and its maximum compression to hold the insert, the overlap by the beginning and end of the beveled surface should be 3-5 mm, which, depending on the type of shoe, corresponds to the angle of inclination of the beveled surfaces 4-8.
