RU24167U1 - DEVICE FOR REPLACEMENT OF ABSORBING DEVICES OF RAILWAY TRANSPORT - Google Patents

Description

A trolley MOVING along the vehicle with a lift mechanism for compressing the absorbing apparatus, including a fork elastically connected horizontally movable relative to each other to cover the friction wedges of the absorbing apparatus and a wedge for placement in the hole of the traction clamp, and a horizontally located hydraulic cylinder; the compression mechanism of the absorbing apparatus is equipped with a hydraulic booster including a housing with stops for interacting with the car frame, mounted with the possibility of vertical movement in guides that are mounted on the lift, a rod mounted on the housing and placed in a vertical bore made in it, and mounted on the lift a sleeve-covering rod and placed by the upper part in the bore, while the cavity formed by the walls of the bore, rod and sleeve is filled with a working fluid and through a pipeline with PORN crane rodless cavity communicates with a horizontally positioned cylinder which is fixed to the housing, the wedge secured to a horizontal rod of the hydraulic cylinder and fork rigidly connected to the housing.

This technical solution will provide advanced safety measures, but not sufficiently productive.

The proposed utility model is designed to increase labor productivity when replacing the absorbing devices of railway vehicles.

This goal was achieved by developing and using a new three-level frame in the device, including a platform lifting frame, a lateral movement frame and a removable cassette frame, the latter equipped with two or more slots for accommodating removable and new absorbing devices to be installed; frames are kinematically connected to each other.

Like the well-known designs, the proposed technical solution contains a trolley with the possibility of movement along the vehicle, on which a telescopic lift is mounted with a mechanism for compressing the absorbing apparatus - a hydraulic unit operating from pneumatic-hydraulic drives.

Unlike analogs and prototypes, the proposed utility model will include a trolley equipped with a three-level frame as part of a platform, a transverse movement frame and a removable cassette frame.

The construction of the utility model is illustrated by a schematic drawing: FIG. 1 general view of the device.

A device for replacing absorbing apparatuses comprises a trolley 1 with wheels equipped with a three-level frame as a part of platform 2, movably fixed on the platform of the transverse frame 3 with rollers for moving along the platform, a removable cassette frame 4 located in the socket of the transverse frame 3, a telescopic lift cylinder 5 with the possibility of lateral movement from

screw drive (not shown in the figure) and with secured in the upper part of the hydraulic squeezing unit 6.

A three-level frame is connected to the trolley using levers 7, the rotation of which is carried out from the power switch 8; in addition, a pneumohydraulic amplifier 9 and control panels with pneumohydraulic lines (not shown in the figure) are installed on the trolley.

The device operates as follows.

Previously, when preparing the device for operation, a removable frame-cassette 4 with one or more absorbing devices to be installed in its sockets is fed to the socket 1 of the transverse frame 3.

On the rail track, the trolley 1 is fed under a wagon or other railway vehicle lifted up on “rails” in such a way that the elevator 5 with the hydraulic unit 6 is under the spine beam pocket with an absorbing device to be replaced; while the lift is additionally centered using a screw drive.

Then, using the telescopic cylinder of the lift 5, the hydraulic unit 6 is lifted up until it contacts the absorbing device and, after centering the grippers relative to the thrust plate and wedges of the absorbing device, the final lifting of the hydraulic unit 6 is carried out, compression using the hydraulic booster 9 of the spring of the absorbing device and its preliminary descent before exiting the nest, after which the compression force is removed and the absorption device is lowered to the position where the removed absorption device is in the appropriate cassette slot 4; then a three-level frame is lifted by turning the levers 7 using a power cylinder 8 and using the transverse frame 3, move the cartridge 4 to a new position so that above the telescopic cylinder of the lift 5 with the hydraulic unit 6 there is a socket of the cartridge 4 with a new or repaired absorbent an apparatus ready for installation in place of the shot; the three-level frame is lowered, while, if necessary, the absorbing apparatus is centered with respect to the hydraulic unit. Then, the pneumohydraulic mechanism for lifting the telescopic cylinder of the elevator 5 with the hydraulic extractor unit 6 is turned on until it contacts the absorbing device and, after additional centering of the grips of the hydraulic extractor unit 6, the spring of the absorbing device is compressed using the pneumohydraulic amplifier 9 and the removable absorbing device is fed into the pocket spinal beam with subsequent removal of the compression force and lowering the lift 5 with the hydraulic unit 6 to the lower dix.

Upon completion of the operation of replacing the absorbing apparatus, the device for replacing the absorbing apparatus of the railway transport is moved on rails under another absorbing apparatus of the car and the above operations are repeated.

Example. The proposed device was developed and manufactured at the Pilot Production Facility of the Scientific Center of the Siberian Branch of the Siberian Branch of the Russian Academy of Sciences (Tomsk) in July 2001. Semi-industrial tests of the device, which is used in two operating modes depending on real production needs, were also performed here:

the first option is the removal of 4 sequentially absorbing devices, i.e. maintenance of two cars without interruptions for transportation of removed absorbing devices to the repair unit;

the second option is the removal of 2 absorbing devices from one car and almost simultaneously installing in place of the removed new or repaired absorbing devices.

Currently, the installation is being mounted in one of the Zap.-sib depot. railroad.

The performance of the proposed installation is 1.5 ... 2 times higher than the serial one.
