Description

Positioning device for eliminating construction errors, mobile contact network and operation method

Technical Field

The invention belongs to the field of electrified railway mobile contact networks, and particularly relates to a positioning device for eliminating construction errors, a mobile contact network and an operation method.

Background

In the traditional railway loading and unloading, a diesel locomotive is adopted to pull a truck to enter and exit a loading and unloading operation area, the mode needs to replace a traction machine head, the railway locomotive is difficult to dispatch and has low efficiency, so that the resource waste is caused, and when a heavy-duty train is encountered, a plurality of shunting diesel locomotives are often needed to meet the traction requirement; in some coal mine departments, a dead zone is set in a loading and unloading operation area by a method that an electric locomotive slides through the loading and unloading operation area by inertia, so that the safety of the loading and unloading operation is ensured. The method of using the inertia of the electric locomotive to slide through the coal loading and unloading operation area is difficult to control the parking point of the locomotive, once the parking space is improperly controlled, the electric locomotive stops in the non-electricity area, and the train can be moved to the electricity area only by spending high rescue cost.

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 cargo handling lines or warehousing maintenance, a rigid movable contact network is adopted, the existing rigid movable contact network system is complex in structure and inconvenient to install, the requirements on the use conditions of the lines are high, and the structural reliability is poor. If the moving contact system moves one side of the whole rail of the section, one mode is to use a motor to drag a catenary so that the contact line side moves to one side of the rail, and the mode has the conditions of insufficient dragging force and unstable operation for the long-distance moving contact system; in the other mode, the motor or the electric push rod is used for driving the rotating bracket to rotate so as to drive the moving section side of the whole moving contact net to move to one side of the rail, and in the mode, the bus bar is integrally arranged at the tail end of the rotating bracket, so that the driving synchronism of the motor or the electric push rod is difficult to control.

At present, one mode uses and is connected with wire rope on the heavy anchor arm, and wire rope passes through the assembly pulley, utilizes electric actuator's cooperation to realize the recovery of contact net, and another mode utilizes motor drive runing rest to realize the side and move.

With the innovation of the electrified railway technology, technical personnel in the field continuously innovate, upgrade the technical innovation and provide an electrified mobile contact network which can 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; also there is the cantilever that adopts mechanical drive to raise the contact net, even raise and also can not move the contact net to the railway outside completely, still can influence the loading and unloading of large cargo, if adopt and rotate the cantilever, with the contact net horizontal hunting to railway one side, also there is the defect that can not swing railway one side completely, its existence is following not enough:

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 moving contact net rotates above the railway or to the side of the railway, the moving contact net may not rotate 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, due to the characteristic of expansion with heat and contraction with cold of the contact line and the catenary, when the rightmost cantilever moves to one side of the rail (the cantilever is approximately parallel to the rail and can be understood as completely swinging to one side to leave a space above the rail), the rest of the cantilevers do not completely rotate to one side of the rail (the cantilever can be understood as not completely swinging to the rail once in the whole overhead contact system, for the long-distance overhead contact system, the swinging stops when swinging to the upper side of the rail side, because the rightmost cantilever swings in place), the rotation cantilever farther away from the right cantilever is smaller in offset, namely when the rightmost cantilever stops rotating, the rest of the cantilevers do not rotate to the position, particularly for the heavy-load train suitable for the long distance, the displacement is about 1600m, when the rightmost cantilever stops rotating after being in place, other cantilevers far away from the right-end cantilever are still in a state of not rotating in place, even above the side of a rail, so that the loading and unloading operation of other goods such as large goods yards, containers and the like can be influenced; in addition, due to the fact that the pantograph does not rotate in place, the pantograph is poor in power taking and contact or cannot contact and take power, and the driving-in or the driving-out of the freight train is affected.

The applicant has had a drawback in the summary of the invention section, and the proposal aimed at explaining this technical problem is also part of the creation of the present invention, and the solution to this technical problem is not found in the presently disclosed technology.

The existing flexible contact network technology comprises the existing practical application technology and does not disclose the defect and a related solution in the prior patent application document, the applicant believes that the scheme for solving the technical defect is provided in the industry for the first time, if the defect cannot be solved, the operation problem of the mobile contact network is directly influenced, so that the potential safety hazard exists in the commercial process of the mobile contact network, and therefore, the applicant provides a set of complete solution through research and applies for intellectual property protection.

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. The locomotive can meet the requirement of cargo handling lines or warehousing maintenance of the existing freight trains of the locomotives, and can be effectively applied to heavy-duty trains such as ten-thousand-ton trains.

In order to achieve the above purpose, it is a conventional practice to fix the catenary and the contact wire to the rotation wrist, and the rotation of the rotation wrist drives the catenary and the contact wire to move from one side of the rail to the upper side of the rail or from the upper side of the rail to one side of the rail. The applicant provides a mode of subverting the traditional arrangement through continuous research and innovation, namely the carrier cable and the contact wire are not fixedly fixed on the rotating wrist arm, so that the carrier cable and the contact wire can not be influenced by construction errors, thermal expansion and cold contraction in the rotating process.

The applicant provides two-direction technical ideas, wherein the first is that the catenary directly makes reciprocating movement on the cantilever structure, the mode also directly omits a catenary clamping seat and a contact wire contact seat in the traditional sense, and the second is that pulling force or pushing force formed in the movement process of the catenary is transmitted to the cantilever structure through a force transmission piece so as to push or pull the cantilever structure to rotate; of course, the other mode can be adopted, the cantilever structure is driven to rotate, and the force formed in the rotation process of the cantilever structure is transmitted to the catenary through the force transmission piece, so that the catenary is driven or pulled to move. The core thinking is that the carrier cable is not fixed to be died on the cantilever structure, only if not fixed to be died, just can overcome the influence that construction error brought to and overcome expend with heat and contract with cold and lead to the carrier cable not in place to rotate the problem, also only if not fixed to be died, just can realize further formation compensation, this patent maximum innovation point also is different from prior art's biggest difference point, and it has brought beneficial effect, has solved the technical problem that prior art can not the technique.

the moving piece 6 moves to drive the force-bearing part to move through the force-transmitting piece, and the force-bearing part transmits force to the cantilever structure 1, so that the cantilever structure 1 is pushed or pulled to rotate;

or

as a preferred embodiment, the moving member 6 is further pulled to further drive the force-receiving portion to move through the force-transmitting member, and the force-receiving portion transmits a force to the wrist-arm structure 1, so as to push or pull the wrist-arm structure 1 to further rotate to realize stroke compensation; supplementary explanation is needed: since the movable part is slidably disposed on the arm structure 1, the moving part 6 can be further pulled when the arm stops rotating

Or

The wrist-arm structure 1 further rotates, the moving piece 6 is further driven to move through the force transmission piece, and the force receiving part transmits force to the moving piece 6 through the force transmission piece, so that the moving piece 6 is pushed or pulled to further move.

The method further comprises the following steps: the elastic force transmission piece 8 is compressed or stretched through the pushing part 7 in the moving process of the moving piece 6, the stress part is pushed or pulled, and the stress part transmits force to the cantilever structure 1, so that the cantilever structure 1 is pushed or pulled to rotate; or

The invention directly changes the traditional inherent scheme, utilizes the carrier cable as a transmission part, and movably arranges the carrier cable (on a fixed and dead cantilever structure), the carrier cable provided by the invention can slide back and forth on the cantilever structure, and has a relative movement relation, the maximum horizontal moving distance of the carrier cable along the horizontal direction can be greater than the rotating horizontal distance of the corresponding cantilever structure, and under the condition of needing supplementary explanation, the maximum horizontal moving distance of the carrier cable along the horizontal direction can be greater than the rotating horizontal distance of the corresponding cantilever structure only under the sliding condition. If the carrier cable is fixed on the cantilever structure, the horizontal moving distance of the carrier cable along the horizontal direction is equal to the rotating horizontal distance of the corresponding cantilever structure. Just because of the relative sliding relationship, the construction error and the influence of expansion with heat and contraction with cold can be eliminated. The structure is innovated just because of the relative sliding relationship, the force transmission piece is utilized to transmit force, and when the catenary is pulled (the force initiating end is an external weight or a dragging mechanism pulls the catenary), the force generated in the movement process of the catenary is transmitted to the wrist arm structure to drive the wrist arm structure to rotate to a working position or a non-working position; when the cantilever structure rotates (when the force starting end is that the cantilever structure is driven to rotate by a rotating motor or a push rod and the like), the force for rotating the cantilever structure is transmitted to the moving part (the catenary cable) by the force transmission part through the force bearing part, so that the catenary cable is driven to move. The mode breaks through the traditional thinking that the catenary needs to be fixedly arranged on the cantilever, and the catenary is driven to move by the rotation of the cantilever or is directly pulled to move in the traditional way; the invention breaks through the traditional thinking that in the moving process or the rotating process of the carrier cable, the carrier cable and/or the contact line have relative moving relation, namely the maximum horizontal moving distance of the carrier cable and/or the contact line along the horizontal direction can be larger than the rotating horizontal distance of the corresponding cantilever structure. The invention has the advantages that the construction error problem is effectively solved, the expansion and contraction problem of the catenary is effectively solved, the problem that the catenary cannot be swung in place once from the side to the railway due to the expansion and contraction of the catenary, which is explained above and is not repeated herein, is solved, the other biggest highlight of the invention is that the whole catenary swings in the side direction, the movable part (catenary) can move back and forth on the cantilever structure due to the sliding arrangement of the movable part (catenary), so that the in-place further stroke compensation provides a foundation, the elastic force transmission part (such as a spring or other elastic force transmission parts) can be used, and the energy storage effect of the elastic force transmission part is used for further pushing or pulling the cantilever structure to swing further to realize stroke compensation, thus, compared with the existing swinging situation, the scheme can perfectly solve the problem, and particularly for a long-distance, such as 1700M, mobile contact net, the catenary and/or the contact line can be perfectly swung to one side of the railway and the swing is in place. The existing mobile contact line, for example, using a rigid contact line or a flexible contact line, the length of which cannot reach 1700M, or using multiple sections of mobile contact lines for splicing, is complicated in parts and construction and high in cost, and certainly or somebody needs to ask about, if a rotating motor is arranged at the root of each wrist arm, the situation that the wrist arm cannot swing in place indirectly can also be achieved. Therefore, the invention has low failure rate, and the structure mode of the invention has the advantages of lowest failure rate, stable and reliable operation, simple and convenient operation and good swing effect.
