SU757452A1 - Lift cabin shoe - Google Patents

Description

The invention relates to the field of lift engineering and can be used to ensure the sliding of moving parts along the guide.

The closest technical solution known to the present invention is a shoe ⁵ of an elevator car, containing a body mounted on the car in the form of a clip, a shock absorber made of sound-proof elastic material mounted on the body, and an insert that interacts with the shock absorber and with the end and side working surfaces of the guide head 11] .

The disadvantage of this device is relatively low reliability, due to the need to replace the liner when worn and work with a gap that exceeds the standard value.

The purpose of the invention is to improve the reliability and lengthening the service life by providing the possibility of adjusting the gap between the working surfaces of the guide head and the liner, depending on its wear.

*

This is achieved due to the fact that the liner contains three bars, one of which is placed at the end and two at the side working surfaces of the guide head, each block of the insert is provided with a bar pivotally connected with it relative to the working surface of the guide.

In addition, the link for adjusting the position of the bar contains two screws through the holes in the housing and fitted with shock absorbers with fasteners, the bars are made with grooves, and the ends of the screws facing the guide are made with ball surfaces that interact with the grooves.

FIG. 1 shows a cabin with shoes mounted on rails; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 section bb in fig. 2; in fig. 4 — section B — B in FIG. one.

Sliding shoes 3 are mounted on the cab 1 suspended on the pull ropes 2,

which she slides along the guides 4

Shoe 3 consists of a fixed on the frame. 5 cab 1 body 6 in the form of a bracket, a shock absorber 7 made of soundproof elastic material installed * on the body 6, and a liner 8 interacting with the shock absorber ₅ and with the front a and side b working surfaces of the head in the guide 4.

The insert 8 is made of three bars, one of which is located at the end surface of the head and in the guide 4, and two at the side surfaces of the head b in the guide 4.

Each block of the liner 8 is provided with a link for adjusting the position of the bar in a direction perpendicular to the working surface of the guide head, in which it is located.

The indicated link contains two screws 9 that are passed through the holes in the housing 6 and insulated from the housing and secured to it by means of shock absorbers 7 and nuts 10 with washers I.

Internal thoriums r screws 9 have spherical surfaces interacting with a groove 35 made in a bar of an insert 8, which is loosely mounted on two screws 9, and there is a gap d between the walls of the groove and the ends of the screws 9 and the ball ends r with a groove form a hinge joint ₃ θ which ensures tracking the bars of the insert 8 for possible bends, curvatures and butt joints of the sections of the rails 4, which reduces the vibration of the elevator car.

The housing b is fixed to the frame 5 with ₃₅ bolts 12 and nuts 13 with washers 14,

The work shoe is as follows.

The shoes 3 fixed on the cab 1 are set ₄₀ using screws 9 and nuts 10 in order to provide the required clearance between the surfaces a and b of the bars of the insert 8 and the working surfaces of the head in the guide 4, after which the installation of shoes is fixed by turning the nuts 10. ₄₅

During the operation of the elevator, the bars of the liner 8 wear out and the gap between them and the working surface of the guide head increases.

When exceeding the allowable size of the gap is made, its adjustment with screws 9 and nuts 10 to the original value.

Possible shocks arising from the movement of the cabin 1 due to the impact of the butt joints of the guide sections, possible bends and curvatures of the latter, are perceived by the liner bars 8 and through screws 9, nuts 10 and washers 11 are transmitted to shock absorbers 7 which they perceive and dampen, protecting the passenger cabin from the effects of possible vibration loads.

Claims (2)
