Description

The utility model relates to devices for the mechanization of track works, in particular, it is intended for lifting the rails of a railway track in order to replace the fastening elements.

Known "Hydraulic two-strand overhead lift" (copyright SU 146328 A1, IPC Е01В 29/22, IPC B66F 5/04, publ. 01.01.1962), made in the form of a rail carriage, on which the engine, hydraulic pump, rail grippers, control panel are mounted and hydraulic jacks pivotally attached to the frame.

Known "Hydraulic two-strand overhead lift" (copyright SU 168745 A1, IPC Е01В 29/22, IPC B66F 5/04, publ. 02/26/1965), consisting of a bogie moving along the rail track, on the frame of which hinged hydraulic jacks with cantilever grips are installed supplied under the foot of the rails, a distribution box with spools providing an independent and adjustable fluid supply to the cylinders of cantilever hydraulic jacks with separate lifting of the rail lines, an engine, a hydraulic pump, a control panel and auxiliary jacks, the rods of which are connected by means of hinges to the ribs rigidly fixed on the cylinders of the cantilever hydraulic jacks.

Known "Two-line overhead lift" (author's certificate SU 205054 A1, IPC Е01В 29/22, IPC B66F 5/04, publ. 11/13/1967), consisting of a trolley moving along a rail track with a pump and a hydraulic jack, the cylinder of which is articulated with P- shaped support frame and is articulated with a piston, the rod of which is connected to a rail grip.

The described overhead lifts are not designed to lift the rail lines separately from the rail and sleepers, which makes it impossible to replace the rail fasteners. The disadvantages also include the possibility of only manually moving them along the railway track and manual installation of the grippers of the track lifts on the rail heads. Structural solutions of the support element of the track lifts do not allow to lift the rail lines in the presence of the rail strings located inside the railway track. The manufacture of the hydraulic pump and the junction box used in the construction requires special equipment. The control panel is located on the overhead lift, which negatively affects the safety of the work performed. The use of two hydraulic cylinders in the structure for lifting will require the use of additional equipment for their joint operation, and also increases the overall dimensions of the structure in width. In addition, the structures of the mentioned track lifts do not provide for the movement of additional cargo, in particular the elements of rail fasteners.

It is known "A device for lifting and joining a rail track" (patent SU 553324 A1, IPC Е01В 29/00, publ. 04/05/1977), containing a trolley with a drive, on which a working body is mounted, including a frame and a support connected to it by means of a power cylinder a pillow, in which guides are located, pivotally connected to the upper ends of the levers of the rail grips. In this case, the frame is equipped with L-shaped guides, planted on the axes of the said hinges, and the levers of the rail grips in the middle part are rigidly interconnected.

In the described device, the rail gripper assemblies are a heavy metal-consuming structure and a gripping mechanism assembly that is difficult to manufacture. The disadvantage is that the design of the support element of the device does not allow lifting the rails in the presence of rail strings located inside the railway track.

It is known "A device for replacing rail fastening gaskets" (patent RU 2320796 C2, IPC Е01В 9/00, IPC Е01В 29/22, IPC Е01В 29/32, publ. 03/27/2008), including a rail cart with a frame, a block mounted on it rail gripper with two pairs of rotary mirror-symmetric rocker arms with rail hooks at the ends and a lifting unit with a two-element stop and a manual hydromechanical drive. The rail gripper unit is equipped with two strips fastened at the upper ends with a tie-handle, each provided with a longitudinal groove, made with the possibility of interaction with the cross member on the frame, as well as a transverse roller at the lower end, made with the possibility of interaction with the inner end faces of a pair of rocker arms, while each of the strips is pivotally connected with the lower end to the connecting rod-link, which is pivotally connected to the slider-bracket, made with the possibility of gripping the pair of rocker arms from the side of their lateral and outer end faces and displacement relative to them.

The device described is not intended to replace all types of rail fastening elements. The disadvantages of this device also include its manual movement along the railway track, manual installation of the device grippers on the railheads and the use of two hand-operated hydraulic cylinders in the structure. In addition, this device is not designed to move additional cargo, in particular, rail fasteners.

It is known "A device for dismantling a rail track" (inventor's certificate SU 1141138 A, IPC E01B 29/00, publ. 02/23/1985), containing a trolley on which a frame with rail grips is mounted with the possibility of vertical movement, each of which has levers with rollers on the upper arms, and a support pad with vertical guides for interaction with the rollers, fixed symmetrically relative to the vertical axis of the frame by means of a power cylinder. The device is equipped with locking elements mounted on the support cushion between the guides for interaction with the protrusions that are made on the upper arms of the levers, while the latter are connected by means of a horizontal axis, and their inner side surfaces are made with recesses for interaction with the axes, which are fixed on the frame in horizontal longitudinal plane. The frame is mounted on a trolley with the ability to move in the transverse horizontal plane.

The disadvantages of the known device are its limited functionality. The applied design of the support pad does not allow lifting the rails by the device in the presence of rails in the railway track due to the location of its supporting surface during the mentioned works in the middle part of the track. It also requires precise installation of the mobile device in a certain place on the railway track to ensure that the pillow rests on the sleeper.

The rail gripper assemblies represent a heavy metal-consuming structure and are fixed on the device frame at a fixed distance from each other, which makes it impossible to install the rails in their original place after they have been lifted on curved sections of the railway track.

To install this device on a railway track, the use of hoisting machines and mechanisms is required.

In addition, the device is not equipped with sensors, therefore, it is required to visually control the lifting height of the rail lines and the state of the rail head grips in the immediate vicinity of the operating device, which is unsafe and can also lead to errors due to the influence of the human factor during control.

Also, the known device is not provided with lighting devices, which limits the performance of work in the dark.

The technical problem to be solved by the claimed utility model is to achieve the possibility of simultaneously lifting both rail threads to a height of 200 mm to replace the elements of rail fasteners on ten sleepers on both sides in terms of removing the linings from the embedded bolts without dismantling them, including in the dark time of day, the performance of the mentioned works anywhere on the railway track and in the presence of rail strings in the track, and with the provision of transportation of fastening elements and loading of the utility model onto a railway platform for transportation to the place of performance of these works without the use of lifting machines and mechanisms, as well as increasing productivity labor by reducing the time when changing the linings of rail fasteners without dismantling the embedded bolts.

The technical result consists in expanding the arsenal of technical means for replacing rail fasteners, which make it possible to mechanize manual labor without involving track machines and manual traveling tools.

The specified technical result is achieved by the fact that the rail-lifting trolley moving along the railway track contains a frame and a transmission mounted on it, a lifting mechanism, a rail head gripper, a hydraulic station with an electric motor, a gasoline electric generator on a stand with a mechanism for changing the installation angle, an electric control cabinet with remote panels, sensors for monitoring grippers and the position of the lifting mechanism, lighting devices, a winch and boxes for fastening elements.

The rail-lifting trolley allows at any time of the day to carry out the simultaneous lifting of both rail lines to a height of 200 mm, thus providing the possibility of replacing the elements of rail fasteners on ten sleepers on both sides, namely, removing worn-out linings from the embedded bolts without dismantling and installing them on them. place of new linings, which increases labor productivity. The trolley ensures the execution of the above-mentioned works when it stops at any place of the railway track and in the presence of rail strings in the track. By means of a winch, the trolley is loaded onto a railway platform for transportation and subsequent unloading from the platform, while the trouble-free operation of a gasoline electric generator is achieved by placing it on a stand with a mechanism for changing the installation angle. Also, the cart is used for transportation of fastening elements.

In addition, the sensors used in the design for monitoring the state of the grippers and the position of the lifting mechanism provide light indication displayed on the front panel of the control cabinet and accompanied by an audible signal, which makes it possible to monitor the state of the mentioned mechanisms remotely and without visual control. The use of remote consoles makes it possible to control the movement, lifting, loading and unloading of the bogie, being at a distance from it, which ensures the safety of work on railway tracks.

Due to the suspension of the tongs on the rods, fixed with their upper part on the cantilever beams in the lugs with the provided grooves, it is possible to install the raised rails in their original place, including when changing the track width on curved track sections.

The technical result is also achieved by the fact that the lower part of the hydraulic lifting mechanism is a U-shaped frame with hinged support elements in the form of skis to eliminate the need for precise installation of the support element of the bogie above the sleeper and the possibility of lifting the rails in the presence of rails laid inside the railway track.

FIG. 1 shows a rail-lifting trolley for changing fasteners, general view; in fig. 2 - the same; in fig. 3 - trolley on the railway track, left side view; in fig. 4 - section Α-A in Fig. 3; in fig. 5 - trolley with raised rail threads, left side view, in Fig. 6 - section b-b in Fig. 5.

The rail-lifting trolley (Fig. 1, 2) for changing fasteners includes a frame 1 designed to absorb power loads when lifting rail lines, and mounted on it a transmission 2, a lifting mechanism 3, a gripper device 4, a rail head, hydraulic equipment 5, electrical equipment 6 , winch 7, boxes for fastening elements 8.

In this case, the transmission 2 (Fig. 3, 4) consists of a non-drive wheel pair 9 and a drive wheel pair 10, connected by means of a chain transmission mechanism to the drive for moving the bogie 11 (Fig. 1).

The lifting mechanism 3, which serves to jointly raise and lower the trolley and the rail lines, includes a movable frame 12 having a U-shaped lower part with supporting elements 13 in the form of skis pivotally attached to it. Rollers 14 are installed on the movable frame 12, combined with the vertical guiding elements 15 of the bogie frame 1, a hydraulic power cylinder 16, sensors 17 for monitoring the position of the lifting mechanism 3, adjustable stops 18 for interaction with the gripper device 4, designed to grip the rail head, monitored by sensors 19 ...

The gripper device 4 contains a carriage 20 with rollers 21 for moving along the vertical guiding elements 15 of the trolley frame 1, cantilever beams 22 with lugs 23 and grooves provided in them, rods 24 installed in the said lugs 23 with the ability to move within the groove and a pliers grip, the cheeks 25 of which are connected to each other and to the lower part of the said rod 24 by means of an axial connection. The gripper also includes shackles 26 and pins 27 for securing them. The pliers are housed in a body with an upper flange 28.

Hydraulic equipment 5 (Fig. 1), designed to provide a working fluid to a hydraulic cylinder and control its operation, contains a hydraulic station and high pressure hoses.

Electrical equipment 6 (Fig. 1) consists of a gasoline electric generator, which is a source of electrical energy, placed on a stand with a mechanism for changing the angle of installation, as well as an electrical control cabinet with remote controls, sensors, an electric motor, lighting devices.

The winch 7 (Fig. 1), designed for loading the bogie onto a railway platform and unloading from it, is equipped with an electric geared motor.

The supporting elements of the movable frame of the lifting mechanism rest on the inclined surfaces of the sleepers inside the track (Fig. 5, 6) when lifting the rail threads simultaneously with the bogie frame.

The rail-lifting trolley works to change the fasteners as follows.

The rail-lifting trolley is delivered to the work site on a railway platform. The cart is lowered onto the railway track along the attached inclined lamellas using the winch 7 (Fig. 1).

The control of the movement of the bogie along the railway track, the raising and lowering of the bogie frame, as well as the switching on of the winch and lighting devices are performed using an electrical cabinet, which includes two remote controls for safe operation on the tracks.

In this case, the electric power supply is provided by a gasoline electric generator placed on a stand with a mechanism for changing the installation angle to ensure its horizontal position when loading the bogie onto a railway platform and unloading it. The operation of the hydraulic cylinder is provided by a hydraulic station.

The trolley moving along the railway track is stopped at the work site (Figs. 3, 4). Under the influence of the hydraulic power cylinder 16, the movable frame 12 of the lifting mechanism 3 (Fig. 1), moving by the rollers 14 along the guiding elements 15 of the frame 1 (Fig. 1) of the bogie, begins a vertical downward movement. At the same time, the gripper device 4 (Fig. 1) installed with support on the adjustable stops 18 of the movable frame 12 moves downwards, the rollers 21 of the carriage 20 of which also move along the guide elements 15 of the frame 1 of the trolley. The gripper bodies, having passed through the technological openings of the trolley frame 1, stop their downward movement due to the abutment of their upper flanges 28 against the surface of the said frame 1. At the same time, the cantilever beams 22 and the pincer grips suspended from them on the rods 24 continue to fall. At the moment of stopping the movement of the cantilever beams 22 when they stop against the flange 28 of the gripper body, the jaws 25 of the grippers close under the rail heads. The control of the carried out gripping of the rail head and the position of the lifting mechanism is performed by sensors 17, 19.

After the abutment of the supporting elements 13 of the U-shaped part of the movable frame 12 in the inclined surfaces of the sleepers (Figs. 5, 6), the trolley with the rail threads is lifted.

When raising the rail threads to a height of 200 mm, work is performed to replace the linings of rail fasteners on ten sleepers on both sides.

Delivery of elements of rail fasteners to the place of work, as well as removal of worn-out elements, is carried out in boxes located on a trolley.

In the dark, the rail-lifting trolley works with the lighting devices on.

After replacing the linings of the rail fasteners, the trolley, performing the described operations in the reverse order, sets the lifted rail threads to their original places, including on curved track sections.
