Description

Extension type supporting device, mobile contact net and operation method

Technical Field

The invention belongs to the field of electrified railway mobile contact networks, and particularly relates to an extension type supporting device, a mobile contact network and an operation method.

Background

With the propulsion of the electric traction of railways, the electric locomotives are adopted to replace the internal combustion locomotives in the transportation of China railway trunks. Electrification is realized in a cargo loading and unloading line or warehousing maintenance. In the prior art, a flexible movable contact net is used, a motor is used for directly dragging a catenary on one side of the flexible contact net to enable a contact line to move to one side of a rail, and the mode has the defects of insufficient dragging force, unstable operation and the like for a long-distance movable contact net with an integral anchor section; because only one balance weight is adopted, the length of the movable contact net is generally not more than 800 m.

The ten thousand ton heavy load train is one kind of superlong and superheavy cargo train driven by two or several machines, and features that: the vehicle has large load capacity; the number of trains is large. According to the main technical policy of the existing railway, 5000t heavy-load freight trains are driven, the effective length of the arrival and departure line of a station is 1050m, 10000t heavy-load freight trains are driven on a special coal conveying line, and the effective length of the arrival and departure line of part of stations is 1700 m. Comprises a unit type heavy-duty train, a combined type heavy-duty train and an entire-row type heavy-duty train.

For such a long-distance heavy-duty train, for example, a ten thousand-ton heavy-duty train of 1400m to 1700m, if the diesel locomotive is used for shunting operation, a plurality of trains need to be separated, and the existing technology has high cost and needs to rent the diesel locomotive to stop at a loading and unloading point; when the electric tractor reaches a loading and unloading point, the internal combustion engine and the electric tractor need to be exchanged, so that the efficiency is extremely low; in order to exchange the traction vehicles, the stop line needs to be repaired and converted newly, and the investment is increased. The key point is that the existing diesel locomotive has no high-power locomotive and cannot pull a heavy-load train. In the existing flexible contact net technology, the technology comprising the existing practical application and the prior patent application document have no flexible movable contact net which can meet the cargo handling line or warehousing maintenance of a ten-thousand-ton train.

The contact wire and the catenary wire in the existing contact net can not be completely moved to the side edge of a railway, under some conditions, a stand column of the moving contact net is closer to a track, the moving contact net is moved to a non-working position and is closer to a train carriage, and the catenary wire and/or the contact wire on the moving contact net can be easily touched when goods are loaded and unloaded.

As shown in fig. 1 and 2, the first part of the present invention provides an extension support device applied in the field of mobile overhead line system, the extension support device comprises a driving mechanism 1, a support structure 2 and an electric conductor 3, wherein

The electric conductor 3 is directly or indirectly arranged on the supporting structure 2;

the driving mechanism 1 is used for driving the supporting structure 2 to move so as to drive the electric conductor 3 to move to a working position or move to a non-working position or drive the electric conductor 3 to switch between the working position and the non-working position;

the supporting structure 2 is positioned at a working position, at least two points can be found on the supporting structure 2, and a connecting line between the two points is marked as a first auxiliary line; the supporting structure 2 is located at a non-working position, and a connecting line between two points at the same position on the supporting structure 2 is marked as a second auxiliary line;

As shown in FIGS. 3 and 4, by way of example, three points A, B and C are labeled on the support structure in FIG. 1, and three points A1, B1 and C1 are labeled at the same location on the support structure in FIG. 2;

as shown in fig. 3, in the work position, the connections a and B form a first auxiliary line, and in the rest position, the connections a1 and B1 form a second auxiliary line, the support structure being moved from the work position to the rest position, the support structure being retracted substantially horizontally, said second auxiliary line being substantially on the extension of said first auxiliary line.

As shown in fig. 4, in the active position the connections a and C form a first auxiliary line, and in the inactive position the connections a1 and C1 form a second auxiliary line, the support structure being moved from the active position to the inactive position, the support structure being retracted substantially horizontally back, said second auxiliary line being substantially parallel to said first auxiliary line.

In the embodiment, the supporting structure 2 further comprises a vertical column 4, and in the process that the supporting structure 2 drives the electric conductor 3 to move, at least part of the body in the supporting structure 2 can move in space to cross one side or two sides of the vertical column 4; or

In the process that the supporting structure 2 drives the electric conductor 3 to move, at least part of the body in the supporting structure 2 can move from one side of the upright post 4 to the other side opposite to the upright post 4.

Here, it is to be emphasized that: the working position guiding electric body 3 (the catenary 31 and/or the contact line 32 are positioned above the railway, the pantograph of the freight train can be lifted to take power, and the non-working position guiding electric body 3 is positioned at the side of the railway, so that the space above the railway is convenient for cargo loading and unloading or train maintenance operation and the like).

In the conventional mobile catenary, a support structure 2 (also referred to as a rotation cantilever) is rotatably mounted on an upright post 4, and the rotation cantilever can swing left and right or up and down to drive a messenger wire 31 and a contact wire 32 to rotate to a working position or a non-working position, in this embodiment, a new driving manner is provided, in which the messenger wire 31 and the contact wire 32 are driven to rotate between the working position or the non-working position by the movement of the support structure 2 itself, where the movement has an important characteristic that the support structure 2 itself can move over one side or both sides of the upright post 4 in the moving process, or at least part of a body in the support structure 2 can move from one side of the upright post 4 to the other side of the upright post 4 opposite to the upright post. The existing rotation wrist arm is fixed at one end or rotationally fixed on the upright post 4, the rotation wrist arm does a rotation left-right swinging or up-down swinging motion relative to the upright post 4, and does not move relative to the upright post 4, or in other words, the rotation wrist arm does not enable at least part of the body in the supporting structure 2 to move spatially to cross one side or two sides of the upright post 4 in the moving process; or alternatively

When the supporting structure 2 does not move so that the electric conductor 3 is driven by the supporting structure 2, at least part of the body of the supporting structure 2 can move from one side of the upright post 4 to the other side of the upright post 4 opposite to the upright post.

As a preferred embodiment, in this embodiment, the driving mechanism 1 drives the supporting structure 2 to move, so as to drive the electric conductor 3 to move away from the upright 4 to the working position; or the driving mechanism 1 drives the supporting structure 2 to move so as to drive the electric conductor 3 to move to a non-working position close to the upright post 4.

It should be added that, in the specific implementation, what angle the support structure 2 is pushed out along is not specifically limited, and in the present invention, it is only necessary to ensure that the support structure 2 moves to push out to drive the electric conductor 3 to move to the working position, or moves to recover to drive the electric conductor 3 to move to the non-working position.

A preferred way provided in this embodiment is: the supporting structure 2 extends out along the basically horizontal direction to drive the electric conductor 3 to move away from the upright post 4 to the working position; or, the supporting structure 2 retracts along the basically horizontal direction to drive the electric conductor 3 to move to the non-working position close to the upright post 4.

Regarding the driving mechanism 1 as a supporting device of the supporting mechanism, the driving mechanism 1 is used for providing a driving force in a substantially horizontal direction for the supporting structure 2, and the driving mechanism 1 drives the supporting structure 2 to move so as to drive the electric conductor 3 to move away from the upright column 4 to a working position; or the driving mechanism 1 drives the supporting structure 2 to move so as to drive the electric conductor 3 to move to a non-working position close to the upright post 4.

It can be seen that in this embodiment, the supporting structure 2 is pushed out along a substantially horizontal direction or pulled back along a horizontal direction, so as to drive the electrical conductor 3 to move to a working position or a non-working position or drive the electrical conductor 3 to switch between the working position and the non-working position.

It should be added to the description here why the supporting structure 2 is basically horizontal, the supporting structure 2 has a length of about 3 meters and a weight, and the conductor 3 disposed at the free end of the supporting structure 2 exerts the influence of tension, expansion with heat and contraction with cold, construction error, and micro deformation caused by long-term use, so that the supporting structure is basically horizontal.

It should be noted that the supporting structure 2 of the present invention also needs to be supplemented, the supporting structure 2 of the present invention is used for supporting and dragging the electric conductor 3, and needs to drive the electric conductor 3 to switch between the working position and the non-working position, the specific form of the supporting structure 2 may be various, for example, a moving rod is used as shown in fig. 1 and fig. 2 of the present invention, and of course, the supporting structure 2 shown in fig. 1 and fig. 2 is only an example, and is not limited to the specific supporting structure 2; it is also adopted to add some reinforcing rods (for reinforcing the stability strength) to the supporting structure 2, which are also part of the supporting structure 2; it is understood that any component or structure attached to the support structure 2 that can be driven to move together or along with the drive mechanism 1 is understood to be part of the support structure 2 and is included in the support structure 2 as defined in the present invention.

The support structure 2 shown in the above embodiments is moved in a horizontal direction or in a substantially horizontal manner to be pushed out or pulled back. In fact, the support structure 2 may also be arranged obliquely.

For example, in this embodiment, the supporting structure 2 and the upright post 4 have a predetermined angle in space, and the supporting structure 2 is pushed out or pulled back along an oblique upper direction or an oblique lower direction, so as to drive the conductive body 3 to move to the working position or to the non-working position or to drive the conductive body 3 to switch between the working position and the non-working position.

For example, the support structure 2 is installed on the upright 4 in an inclined manner directly or indirectly, when the support structure 2 is pushed out (pushed out or pulled back along an obliquely upper direction or an obliquely lower direction), the support structure 2 and the upright 4 have a certain included angle in space (preferably 0 to 60 degrees, and other angles or angles exceeding 60 degrees may be selected according to field installation conditions), as long as the support structure 2 drives the conductor 3 to push out, and then the pantograph of the freight train located above the railway can take power.

What is the benefit of doing so? The freight transportation loading and unloading are convenient, and the freight station generally adopts a gantry crane or a forklift to hoist loading and unloading tools; because the mobile contact net is positioned at one side of the railway, the existing method is that only the other side of the railway can be loaded and unloaded by adopting a forklift; if the structure of the embodiment is adopted, the height of the upright post 4 can be set to be basically level with the freight train or lower than the height of the freight train, and the supporting structure 2 is arranged on the upright post 4, so that the supporting structure 2 can be pushed out or extended out along the oblique upper direction to be positioned at a working position, and the freight train can be driven into or out of the freight station; after the train stops, the supporting structure 2 is moved and recovered, at this moment, the supporting structure 2 can be at least in a non-working position, the supporting structure 2 is at least lower than the highest point of the freight train or lower than the upper surface of the freight train, the upper space can be effectively made, the gantry crane or the forklift can be used for loading and unloading operation from two sides of the railway, and the loading and unloading efficiency is greatly improved. The existing mobile contact system has no such mode, and belongs to an innovative scheme developed by the applicant.

In the embodiment, the driving mechanism 1 comprises any one or more combinations of a motor, an electric push rod, a hydraulic push rod, a pneumatic push rod, a chain transmission and a gear transmission;

any one or more combinations of the motor, the electric push rod, the hydraulic push rod, the pneumatic push rod, the chain transmission and the gear transmission are used for directly or indirectly providing driving force and acting on the supporting structure 2 so as to drive the supporting structure 2 to move.

In the present embodiment, fig. 1 and 2 show a driving form using a push rod to drive the supporting structure 2 to move.

In a preferred embodiment, the driving mechanism 1 is directly or indirectly disposed on the upright 4, and the supporting structure 2 is directly or indirectly disposed on the driving mechanism 1.

Under the important supplementary explanation, in order to solve the problem of the lateral pulling of the support structure 2 caused by the thermal expansion and contraction of the electric conductor 3 and the pulling force at the two ends of the electric conductor 3, if the lateral pulling of the support structure 2 exceeds a certain force, the support structure 2 is easily pulled to deform or irreversibly damaged, and the service life of the mobile catenary is affected, in this embodiment, a force adjustable device is adopted, the acting force provided at the two ends of the mobile catenary is only applied to the electric conductor 3 or mostly applied to the electric conductor 3, so that a rotating mechanism needs to be installed on each upright post 4, and the rotating mechanism mainly aims to solve the problem of the damage to the support structure 2 caused by the lateral pulling force. The factors that cause are many, for example, the expansion with heat and contraction with cold of electric conductor 3, the installation construction error of removing the contact net all leads to the lateral tension that bearing structure 2 between stand 4 and the stand 4 is inhomogeneous easily.
