Description

Field of technology

The invention relates to devices for cleaning rail strands, in particular long 800-meter rail strands P65, when loading them onto a rail train in a short time from the middle of the track on a stretch.

State of the art

The use of removable equipment for tightening rail lashes is convenient from the point of view of the possibility of its quick installation on different rail trains, if necessary, and the same quick dismantling.

Equipment for tightening rail lashes is known (Chinese patent No. 110691727, published on January 14, 2020), which contains a modular unit installed on the platform of a rail vehicle on a frame in the form of a beam, a gantry crane, a hydraulic unit, an internal combustion engine with a fuel storage tank, rail clamps for blocking rail lashes.

The disadvantage of this solution is the use of a removable modular block and rail clamps only for fixing the rail strands loaded onto the platform of the rail stock. In this case, a gantry crane is used to tighten the rail lashes, which generally makes the considered solution cumbersome and inconvenient.

There is known equipment for pulling up rail strands (USSR author's certificate No. 136880, published in 1961), taken as the closest analogue to the claimed solution, which is self-propelled and at the same time contains a winch with drums, each of which has ropes with gripping devices wound around them.

The disadvantage of this solution is the presence of jerking actions during the movement of the winch drums when tightening the rail lashes onto the platform, which leads to impacts of the rail lashes on the platform, and, as a result, damage to the rails and the platform itself, reducing the safety and reliability of the work on cleaning the rail lashes. To reduce the manifestation of this effect, they try to tighten the rail lashes more smoothly and accurately, while the time required to carry out work on the railway tracks increases, which is unacceptable.

The technical problem of the present invention is to overcome the technical shortcomings inherent in analogues, and to create a removable module with rail stock equipment for pulling up rail strands, allowing for its quick installation on the rail stock platform, as well as the necessary speed and reliability of work on removing rail strands.

Essence Revealing

The technical result of the invention is to increase safety when carrying out work on cleaning rail strands by ensuring uninterrupted and smooth operation of the devices included in the equipment of the rail vehicle for tightening rail strands.

The technical result is achieved by using a removable module with rail equipment for pulling up rail lashes, which contains a traction portal, including winches with drums, cables and rail grips, while the traction portal contains two hydraulic winches and two drums, the removable module also contains a hydraulic station, including a pumping unit, which is connected to a diesel engine through a transfer gearbox and is configured to convert the mechanical energy of a diesel engine into the energy of a flow of working fluid with stepless flow control; two hydraulic motors installed in hydraulic winches and configured to convert the flow of working fluid into the energy of rotational movement of hydraulic winches, hydraulic distributors designed to direct the flow of working fluid through oil lines to the hydraulic motors, control and regulating equipment designed to protect the hydraulic station from overloads.

The implementation of a traction portal with two hydraulic winches and drums in the presence of an autonomous hydraulic station makes it possible to make the work of cleaning rail lashes uninterrupted.

This is also facilitated by the presence of hydraulic distributors that promptly direct the flow of working fluid through oil pipelines to the hydraulic motors of the winches, as well as the presence of control and regulating equipment that makes it possible to monitor and prevent failure of the hydraulic station from overloads.

The constructive implementation of the conversion of the mechanical energy of a diesel engine into the energy of the flow of working fluid with stepless flow control, as well as the conversion of the flow of working fluid into the energy of the rotational movement of hydraulic winches allows you to quickly and at the same time smoothly load rail lashes onto the platform of the rail stock, thereby eliminating their uncontrolled and destructive impacts on the platform.

A removable module with rail equipment for pulling up rail lashes consists of a frame 1, a roof 2, doors 3 (Fig. 1), walls 4 (Fig. 2).

In a removable module on frame 1 there is a traction portal containing two hydraulic winches 5, two drums 6 (Fig. 3) with cables and two rail grips (not shown).

Hydraulic winches 5 are controlled using a remote control.

Rail grips are necessary for securing the cables of hydraulic winches 5 to the heads of the rail lashes.

The rail grip (Fig. 4, 5) consists of two clamping parts 7, fixed on the first axis 8. On each side of the rail grip on the second axis 9, locking strips 10 are installed to prevent the clamping parts of the grip from opening when tightening the rail lashes. Also, the rail grips have stops 11 that do not allow the winch cable 5 to jump off it. This design of the rail grip allows you to quickly install and remove it on any section of the rail string, as well as quickly engage the winch cable 5 to it.

Also, the removable module 1 contains a hydraulic station, including a pumping unit 12, which is connected to a diesel engine through a transfer gearbox (Fig. 2).

Pumping unit 12 belongs to the power part of the hydraulic station. It is designed to convert the mechanical energy of a diesel engine into the energy of a flow of working fluid with stepless flow control. The pumps provide a stepless change in the supply of working fluid from zero to the maximum value.

In addition, the hydraulic station contains two hydraulic motors (not shown) installed in hydraulic winches 5 and configured to convert the flow of working fluid into the energy of rotational movement of the hydraulic winches 5.

The hydraulic station also contains hydraulic distributors (not shown), designed to direct the flow of working fluid through oil lines to the hydraulic motors, and control and regulating equipment (not shown), designed to protect the hydraulic station from overloads. It allows you to establish a certain sequence of operation of the actuators, ensure the required speeds of movement and forces on the working bodies.

The working fluid is mineral oil with a given kinematic viscosity depending on the time of year.

Removable module 1 is installed on the platform of the rail stock and is secured through the rack-mount brackets of the platform using beams and brackets.

To protect the platform's locking mechanisms from impacts from the rail lash when pulling up, a bump stop and brackets are additionally installed on it.

The bumper is a welded structure consisting of stiffeners and plates.

For the safety of operating personnel in the event of a cable break, all platforms following the locking platform are equipped with supports in which the guards are secured.

Carrying out the invention

The equipment allows you to pull up both standard 800-meter rail strands and shortened rail strands of any length.

The pair of rail lashes is pulled up using cables through two drums 6 using two hydraulic winches 5. When the hydraulic distributors are turned on, working fluid is supplied under pressure to the hydraulic motors of the winches 5.

Fuel is supplied to the diesel engine via the fuel tank 13. Power is supplied via the battery 14 (Fig. 3).

The electrical equipment is placed in the distribution box 15 (Fig. 3). It is designed to supply electricity and ensure the operation of devices in a given technological cycle.

A remote control panel is connected to the distribution box through the gland, with the help of which the operation of all equipment in removable module 1 is controlled.

Thus, the equipment located in removable module 1 allows you to quickly and safely, both for personnel and for the equipment itself, carry out a set of works on pulling the rail lash onto the locking platform of the rail stock.
