Description

Mobile contact net compensation mechanism and mobile contact net

Technical Field

The invention belongs to the field of electrified railway mobile contact networks, and particularly relates to a mobile contact network compensation mechanism and a mobile contact network.

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. At present, a rigid movable contact net system is adopted, but the existing rigid movable contact net system has extremely high cost, complex structure and inconvenient installation, has high requirements on the use conditions of the line and poor structural reliability; the motor is used for driving the rotating support to rotate so as to drive the moving section of the overall moving contact net to move to one side of a rail, in the mode, the bus bar is integrally arranged at the tail end of the rotating support, and the motor is more and difficult to control the synchronism of the motor or the driving of the electric push rod.

With the innovation of the electrified railway technology, the technical personnel in the field can continuously innovate the electrified contact net by providing the electrified contact net which can continuously meet the requirements of cargo handling lines or warehousing maintenance.

Disclosure of Invention

In the prior art, a flexible movable contact net is also used, and a motor is used for directly dragging a catenary on one side of the flexible contact net to move a contact line to one side of a rail; it has the following disadvantages:

1. expansion with heat and contraction with cold certainly can cause the extension of contact wire, catenary, probably leads to bow net trouble (train pantograph and catenary trouble), for example the compensation arrangement that adjusts the cable tension falls to the ground, the cantilever skew, locator breaks away from serious incident such as. If the contact wire is loosened and wound on a pantograph (a transverse plate which is high above the locomotive head) of the train, the contact net rod is dragged down, the locomotive falls off the track, and the carriage falls down, so that the consequence is very serious.

2. The carrier cable and the contact line are fixedly arranged on the rotating wrist arm, and construction errors exist in the spacing and verticality between the stand columns and the tension degree of the carrier cable and the contact line between the wrist arms. 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. For such a long-distance heavy-duty train, for example, a ten thousand-ton heavy-duty train of 1400m to 1700m, due to the influence of thermal expansion and cold contraction and the existence of construction errors, when the mobile catenary swings to the upper side or the side of the railway, the swing is not in place.

The existing method is that a weight is arranged at one end of a mobile contact network, a dragging mechanism is arranged at the other end of the mobile contact network, and a catenary cable and/or a contact line are/is pulled by the dragging mechanism, so that the contact line is moved from one side edge of a rail to the upper side of the rail or from the upper side of the rail to one side edge of the rail.

Through the continuous research and practice of the applicant, the above solution enables the effective implementation of driving the catenary and/or contact line to move to one side of the rail or above the rail, but in practice a new problem arises: the cantilever is arranged to rotate rightwards to drive the contact line and the catenary to move to one side of the rail, and due to the fact that the contact line and the catenary have the characteristics of thermal expansion and cold contraction, when the rightmost cantilever moves to one side of the rail (the cantilever is approximately parallel to the rail), the rest of the cantilevers do not completely swing to one side of the rail, the farther the rotating cantilever is away from the right cantilever, the smaller the offset is, namely when the rightmost cantilever stops swinging, the rest of the cantilevers do not rotate to the position, particularly when a heavy-duty train suitable for long-distance overhead contact systems moves about 1600 meters, when the rightmost cantilever stops swinging after being in position, the other cantilevers far away from the right cantilever are still in the state of not swinging to the position, even are positioned above the side of the rail, and therefore loading and unloading operations of other goods such as large goods yards and containers can; in addition, due to the fact that the pantograph does not swing in place, the pantograph is poor in power taking and contact or cannot contact and take power, and the driving-in or driving-in position of the freight train is affected.

In order to realize the purpose, the applicant provides a set of technical scheme which can effectively solve the defect that the movement of a catenary and a contact line is not in place in the existing mobile contact network, and compared with a rigid contact network, the mobile contact network has the advantages of lower cost, more reliable operation, less weather influence and simpler maintenance; the contact net provided by the application overcomes the defect that the original dragging mode is adopted for moving, the gravity supplementing mode is used for moving, and the integral movement of a longer distance (1600m-1700m) can be realized by effectively improving the existing contact net.

In the embodiment provided by the invention, one end of the spring is arranged on the carrier cable, the other end of the spring is arranged on the supporting device, the carrier cable moves to compress or stretch the spring, and the pushing force or the pulling force formed by the spring acts on the supporting device so as to push or pull the supporting device to rotate; or

One end of the spring is arranged on the contact line, the other end of the spring is arranged on the supporting device, the contact line moves to compress or stretch the spring, and the pushing force or the pulling force formed by the spring acts on the supporting device so as to push or pull the supporting device to rotate.

The following provides an example further optimized on the basis of the above embodiment;

as shown in fig. 19, a clamp mechanism 12 is also included in this embodiment, the clamp mechanism 12 being disposed on the messenger line and/or the contact line. The clamping mechanism which clamps the messenger and/or the contact wire is able to move with the messenger and/or the contact wire.

The clamping mechanism is arranged on the carrier cable in the following mode:

the first method comprises the following steps: the clamping mechanism is arranged on a carrier cable in the bearing structure (sleeve); as shown in fig. 20.

And/or

And the second method comprises the following steps: the gripping mechanism is located on the messenger wire on one side of the support structure or on both sides as shown in fig. 19.

the clamping mechanism clamps the contact wire, the supporting structure and the supporting device are arranged in a sliding mode, and the clamping mechanism slides on the supporting device through the supporting structure. Reference may be made herein to the embodiment of fig. 8.

The sliding contact position is the position where the carrier cable is in sliding contact with the bearing structure, the clamping mechanism in the embodiment mainly plays a role in limiting, half clamping is arranged on any side of the sliding contact position, and full clamping is arranged on both sides of the sliding contact position; if both sides are arranged, the embodiment is called as the situation without clamping.

It should be added that, the advantages brought by the arrangement of the single moving mechanism containing the clamping structure are not easy to see, and the moving mechanism containing the clamping structure is placed into an integral moving contact net, and comprises a plurality of supporting devices, the supporting devices adopt the moving mechanism containing the clamping structure in the embodiment, the carrier cable and/or the contact wire penetration length is arranged on the supporting devices, and in the operation process, when one supporting device at the extreme side swings to the right position to stop rotating (the supporting device can be stopped to stop rotating by adopting a limit structure, the limit structure is not a point protected by the patent, and can be stopped to stop rotating by adopting any mode or the existing mode), the rest supporting devices far away from the supporting device stopping rotating do not swing to the rail completely, at the moment, the carrier cable and/or the contact wire is further pulled, and the clamping structure is abutted against the supporting structure, the supporting structure is pressed to push the supporting device to rotate further. Of course, this is the key technical idea at the heart of this patent technology, and conventionally, since the catenary and the contact wire are fixed on the supporting device, when the supporting device at the extreme side is rotated to the position, the catenary and/or the contact wire cannot be further pulled, so that the rest of the supporting devices in the catenary cannot be rotated to the position.

In order to enable a person skilled in the art to clearly understand, the requirement fully disclosed in the patent is met, and why the situation that the rest supporting devices are not rotated in place exists, if the rigid contact system exists, a rotating motor is arranged on each upright or a plurality of uprights to drive the cantilever to rotate, the rigid contact system (rigid on a contact line) can gradually transmit force, and the situation that the rotation is not in place does not exist. The high-speed railway is taken in the life, what the subway looked is fixed flexible contact net, and the movable flexible contact net that this patent provided mainly is used in places such as large-scale goods yard, railway container goods handling, warehousing maintenance.

The flexible contact line is adopted between the upright posts, due to construction errors and the influence of expansion with heat and contraction with cold of the contact line and the carrier cable, the contact line is especially long-distance and even used for ten thousand tons of heavy-duty trains, and the situation that the rest supporting devices in the contact line cannot rotate in place is more obvious as the distance is longer. The patent provides a solution based on the angle to find the problem.

So to say, in this field, in such a scenario, conventionally, since the catenary and the contact wire are fixed to the support devices, when the first support device on the extreme side is rotated into position, the catenary and/or the contact wire cannot be pulled further, so that there is a case that the rest of the support devices in the catenary are not rotated into position.

This problem has existed since the day of flexible mobile catenary systems, and prior disclosures of prior art, and none have been found or found to disclose, or more particularly, provide a solution to, the problem for a time. The messenger is able to move relative to the support means; or the contact wire can be movable relative to the support means. The innovative idea itself breaks through the traditional thinking, subverts the existing fixing mode, is not a technical solution which is easy to think by the technical personnel, if the innovative idea can be easily imagined, there should be a prior technical disclosure in the early days, the prior art is supposed to be fixed on the supporting device in the field, in the prior art, after the most edge supporting device rotates in place, no technical disclosure is available to further move the carrier cable or the contact wire, the technical shortage that the rest supporting devices do not rotate in place is solved by adopting the mode, the possibility of other aspects is not considered, and therefore, the research and development of the technical field are hindered, and the technical point provided by the patent overcomes the technical prejudice.

The embodiment further provides a flexible contact system, which includes a plurality of support devices, and the support devices employ the compensation mechanism of claim 22.

As shown in fig. 38, the case where the weight device 14 is provided on one support device is shown. All the overhead lines described above in this embodiment may be provided with a counterweight device 14, as defined in the claims. At least one of the support devices may be provided with a counterweight device 14, depending on the application. .

In the invention, the traditional inherent scheme is directly changed, and the carrier cable can move relative to the supporting device; or the contact line can move relative to the supporting device, so that construction errors and the influence of expansion with heat and contraction with cold are eliminated.

The supporting device is arranged on the upright post in a rotating way and can rotate under the action of any pushing force, so that the supporting device is pushed or pulled to rotate by using the force transmission mechanism, and therefore, even if one supporting device at the extreme edge rotates to the position, the supporting device can be pushed or pulled to further swing by only needing to further pull the catenary and/or the contact line through the arranged force transmission mechanism, and the problem that all supporting devices in the existing movable contact net cannot swing in place can be solved.

As a preferred embodiment, in this embodiment, when at least one support means (typically the last support means) of the catenary stops rotating, the catenary and/or contact wire can further move on the support means. The maximum horizontal travel distance of the messenger and/or contact line in the horizontal direction can be greater than the rotational horizontal distance of the corresponding support means. As shown in fig. 39, after the messenger and/or contact wire moves from point a to point B, the horizontal distance L1 that the messenger and/or contact wire moves is greater than L2, as can be seen in fig. 40, where the towing mechanism 13 is used to pull the messenger and/or contact wire through an external towing mechanism 13 (shown in fig. 40) onto a number of support devices; so that the messenger and/or contact line moves from point B to point B' and the total distance the messenger and/or contact line travels in the horizontal direction is L2.

As shown in fig. 41, the messenger and/or contact wire moves from point a to point a ', and since the messenger and/or contact wire is slidably mounted on the support means, the messenger and/or contact wire has a slippage relative to the support means during movement, and therefore moves from point a to point a' by a horizontal distance L1, which corresponds to a horizontal distance L2 for the support means to rotate, i.e., L1 is always greater than L2 at any position during rotation as long as the messenger and/or contact wire has a relative slippage relative to the support means during movement.

Of course, there may be at least one rotation mechanism for driving the support means to rotate, said rotation mechanism driving the support means to rotate to move said messenger and/or contact wire to a non-operative oscillation.

Supplementary explanation is as follows: the purpose is to make the carrier cable, the contact wire and the supporting device all rotate to the non-working position, the supporting device can be driven to rotate by the pulling force of the carrier cable and/or the contact wire in a mode of pulling the carrier cable and/or the contact wire, the supporting device can also be driven to rotate by a rotating motor, and the carrier cable and/or the contact wire is driven to move to the non-working position by the rotation of the supporting device.

The largest innovation point of the overhead line system is that the maximum horizontal moving distance of the catenary and/or the contact line along the horizontal direction can be more than or equal to the rotating horizontal distance (the length of a rotating radius) of the supporting device. Another way is to say that the carrier cable and/or the contact line are not fixed on the supporting device. The traditional catenary and contact line are fixed on the cantilever, the moving distance of any cantilever in the horizontal direction or the movement distance of the catenary in the horizontal direction under the pulling of the catenary is smaller than or equal to the rotating radius of the cantilever, and particularly in a long-distance moving contact network, due to the construction error and the influence of thermal expansion and cold contraction, for example, in summer, after the cantilever a is rotated in place and stopped, the cantilever c and the cantilever d which are farther away from the cantilever a cannot be rotated in place.

In this patent with the gliding setting of whole carrier cable or contact line on a plurality of strutting arrangement, firstly overcome construction error's influence, no matter winter or summer, effectual reduction or neglect expend with heat and contract with cold and to strutting arrangement pivoted influence.

Insofar, it will be appreciated by those skilled in the art that, i.e. in the case where the messenger and/or the contact wire is slidable, the maximum horizontal travel distance of the messenger and/or the contact wire in the horizontal direction can be greater than the horizontal distance of rotation of the corresponding support means.

In addition, it is necessary to supplement that the present invention further includes a rotating mechanism, and the embodiment and the drawings provided above provide a top view, so that the rotating mechanism is not embodied. As shown in fig. 42, in the present embodiment, the rotating mechanism 15 is disposed on the supporting device 3, and the supporting structure 7 is disposed on the rotating mechanism 15; the rotating mechanism 15 is provided with a supporting rotating shaft, the bearing structure 7 is arranged in the supporting rotating shaft, pushing force or pulling force formed by a carrier cable or a contact line is directly or indirectly transmitted to the bearing structure 7, the bearing structure 7 moves leftwards or rightwards, the supporting device is stressed to rotate along with the bearing structure, and the bearing structure 7 and the supporting device 3 are in relative rotation through the rotating mechanism 15, so that the actuation is convenient.

As shown in fig. 43, the protection mechanism is provided on the rotation mechanism 15 in the present embodiment. The protection mechanism 8 is provided on the rotation mechanism 15. Through the arranged rotating mechanism 15, the protection mechanism 8 and the supporting device 3 have relative rotation relation, and the actuation is convenient.
