Description
Technical Field
The invention relates to the technical field of bridge frame replacement, in particular to whole-hole beam frame replacement equipment.
Background
Along with the increase of the running time of the railway and the highway in China, the aging problem of the bridge has increasingly prominent safety influence on the operation of the existing line (the established line). Some bridges are not long-lived in construction because of the continuous acceleration of existing lines, particularly main trunks, and the need to pass heavy trains, resulting in inadequate strength or rigidity and having to be replaced. Some bridges are also produced with partial damage each year due to poor manufacturing and installation quality.
In addition, in the past railway manufacture of China, a large number of steel beams are used, the service lives of the steel beams are obviously lower than that of concrete beams, the maintenance workload of the steel beams is great, and some places cannot be maintained at all, so that part of the steel beams need to be replaced before the steel beams reach the strength life. Therefore, it is urgent to study one or several safe and reliable existing railway line bridge girder changing methods for different bridge forms.
The existing railway line bridge frame changing method in China comprises a full-closed existing line bridge frame changing method and an intermittent closed existing line bridge frame changing method.
The idea of the totally-enclosed frame-changing beam is to build temporary lines or temporary bridges near the existing railway bridges; the train passes through temporary convenient lines or temporary bridges, and bridge replacement is carried out by using a bridge girder erection machine. The operation mode is suitable for bridges in river channels or valleys without stopping driving, but a stool line or a stool bridge needs to be built, a line needs to be restored after frame replacement, the cost is high, the speed is limited when a train passes through the stool line (the stool bridge) for a long time, the point construction is needed when the stool line is in butt joint with a positive line and the positive line is in butt joint with the positive line, meanwhile, the line is frequently disturbed, the instability of a roadbed and a ballast bed is caused, the speed limiting time is long, and the influence on the operation of the positive point of the train is large; the construction and dismantling of the toilet line has great influence on the environment.
The idea of intermittently closing the frame-changing beam is to implement the frame-changing operation of the bridge by using the schemes such as gantry crane or bracket transverse movement and the like by adjusting the train operation diagram or train operation gap. The operation mode does not need to build a stool line, has low cost and no environmental pollution; the preparation time is short, and the bridge frame replacement work can be carried out in a short time; the disturbance to the existing line is small, and the normal operation can be restored within a short time after the frame replacement is completed. The preparation work is carried out on line, has no interference to the existing line, but cannot be applied to bridges above valleys or rivers. The intermittent sealing for replacing the existing line bridge has no convenient line for the vehicle to detour, so the safety and reliability of the equipment and the sealing time become the important matters of the scheme.
For the problems, a set of brand-new railway girder bridge frame-changing construction technology and equipment which can be suitable for various bridge pier heights or under-bridge terrains and landforms are urgently needed to be provided, a new thought and method are provided for bridge frame-changing engineering, and frame-changing construction of the whole-hole Liang Jiliang sheets, railway ballasts and track panels is safely and efficiently completed in a 'skylight point' on the premise of ensuring the minimum interference to original line equipment.

Referring to fig. 7, in some embodiments, both ends of two stringers 202 extend beyond the cross beam 201 and form a guide beam 203, the guide beam 203 being used to guide the gantry crane 500 into the stringers 202 or out of the stringers 202.
In order to facilitate the gantry crane transfer vehicle 600 to mount the gantry crane 500 on the guide beam 200, both ends of the two longitudinal beams 202 of the guide beam 200 extend out of the cross beam 201 to form the guide beam 203, the gantry crane transfer vehicle 600 drives the gantry crane 500 to move between the two guide beams 203 arranged on the same side, and mounts the gantry crane 500 on the guide beam 203 or drives the gantry crane 500 to be separated from the guide beam 200. Specifically, the gantry crane 500 is in a low position in an initial state, and the bottom of the gantry crane 500 is supported on the surface of the first special beam transporting column, so that the rail height limit is avoided being exceeded, and when the gantry crane transfer vehicle 600 moves between the two guide beams 203, the supporting part is driven to rise through the extension of the lifting part 703, so that the bottom surface of the gantry crane 500 is higher than the plane where the top of the guide beam 203 is located.

Referring to fig. 8, in some embodiments, the guide beam 203 is hinged to the longitudinal beam 202, and a first adjusting device 204 is connected to the guide beam 203, where the first adjusting device 204 is used to drive the guide beam 203 to swing along its hinge with the longitudinal beam 202.
Specifically, the guide beam 203 swings in the horizontal direction with respect to the side member 202, and the first adjusting device 204 is hingedly provided between the guide beam 203 and the side member 202, and in order to facilitate the installation of the first adjusting device 204, the guide beam 203 swings in the horizontal direction toward the inside of the side member 202. The first adjusting device 204 includes a first driving portion and a first telescopic portion, the first driving portion is hinged on the longitudinal beam 202, and the first telescopic portion is hinged on the guide beam 203.

In order to provide enough operation space for beam replacement, the width of the guide beam 200 is generally larger than the width of the whole hole beam surface of the frame to be replaced, which results in larger width of the guide beam 200, and in the transportation process, an overrun phenomenon may occur, which affects normal transportation of the guide beam 200. Therefore, two ends of the two cross beams 201 can be hinged with the longitudinal beams 202, the longitudinal beams 202 are connected with the second adjusting device 205, the second adjusting device 205 is used for driving the longitudinal beams 202 to swing along the hinged positions of the longitudinal beams and the cross beams 201, the guide beams 200 shrink in the transportation process, the guide beam transfer trolley 100 drives the guide beams 200 in the shrinkage state to move, after the guide beam transfer trolley 100 drives the guide beams 200 to move to the position above the hole site of the frame to be replaced, the guide beams 200 are unfolded, and the distance between the two longitudinal beams 202 of the unfolded guide beams 200 is larger than the width of the beam piece.
The second adjusting means 205 comprise a telescopic member hingedly arranged between the transverse beam 201 and one of the longitudinal beams 202. Wherein, the extensible member includes second drive division and second telescopic part, and second drive division sets up on longeron 202, and second telescopic part can dismantle with crossbeam 201 and be connected to, the flexible demand can be satisfied to the setting position and the setting angle of second telescopic part and second drive division, drives the flexible time of second telescopic part through the second drive division promptly, can relative swing between longeron 202 and the crossbeam 201. When the guide beam 200 is contracted, the end part of the second telescopic part is connected with the cross beam 201, and the second telescopic part is driven to move by the second driving part, so that the longitudinal beam 202 and the cross beam 201 swing relatively, and further the two longitudinal beams 202 are close to each other, and the contraction of the guide beam 200 is realized.

Referring to fig. 6, a rotation arrangement mode may also be adopted between the lifting device 106 and the connecting piece 107 on the guide beam transfer vehicle 100, the lifting device 106 may preferably be a hydraulic cylinder, the connecting piece 107 is connected with the longitudinal beam 202, and the rotation of the connecting piece 107 drives the longitudinal beam 202 to rotate relative to the transverse beam 201, so as to complete the unfolding and retraction process of the guide beam 200. Specifically, the connecting member 107 includes a turntable 108 rotatably disposed on a telescopic rod of the hydraulic cylinder and a boom 109 symmetrically disposed on both sides of the turntable 108, and a connecting rod 110 for connecting with a longitudinal beam 202 is disposed at the bottom of the boom 109.

The using method of the frame changing device provided by the application comprises the following steps:
Firstly, preparation before construction is carried out, steel rails and rail panels at two ends of a beam sheet to be replaced are cut, and certain limits can be occupied after equipment installation is completed, so that the overhead line system upright post of a cross-region of the beam to be replaced needs to be rotated by 90 degrees and the overhead line system is shifted.
Referring to fig. 1-5, step one, a guide beam transfer vehicle 100 transfers a guide beam 200 to a position above a hole site of a frame to be replaced, and lowers the guide beam 200, wherein the guide beam 200 comprises a cross beam 201 arranged on an existing bridge at two sides of the hole site of the frame to be replaced and a longitudinal beam 202 for providing a walking track for a portal frame, and a lintel area for a frame replacement sheet to pass through is formed between the cross beam 201 and the longitudinal beam 202; the first conveyor Liang Zhuanlie conveys two first gantry crane transfer vehicles and gantry cranes 500 respectively positioned on the two first gantry crane transfer vehicles to one side of the guide beam 200, and the second conveyor Liang Zhuanlie 302 conveys a beam to be replaced to the other side of the guide beam 200;
Wherein the movement of the first rail Liang Zhuanlie to one side of the guide beam 200 and the movement of the second rail Liang Zhuanlie to the other side of the guide beam 200 described herein refers to the post-transport state, i.e., the final drop position, and does not refer to the order in which the first rail Liang Zhuanlie 301, the guide beam transporter 100, and the second rail Liang Zhuanlie are moved. Preferably, the second ship Liang Zhuanlie, the guide beam transfer vehicle 100 and the first ship Liang Zhuanlie are sequentially arranged to synchronously enter in the direction towards the construction site, so that landing efficiency is improved.
Specifically, the first gantry crane transfer vehicle walking on the first transport Liang Zhuanlie drives the gantry crane 500 to rotate to the transport position, so that the length direction of the gantry crane 500 is consistent with the length direction of the first transport Liang Zhuanlie, the distance of the width of the first transport Liang Zhuanlie 301 in the transport process is reduced, and the situation that the tunnel limit is exceeded is avoided. When the ship Liang Zhuanlie runs on a normal road section, the beam plates are supported by the two-pack girder trolley 402. And when the tunnel section is passed, the temporary support piece on the second transport Liang Zhuanlie is lifted to support the beam piece, so that the beam piece is separated from the second beam carrying trolley 402, the temporary support piece is lowered after the second beam carrying trolley 402 is avoided, the beam piece is supported on the special row of the transport beam, the height of the second transport Liang Zhuanlie is reduced, and the scraping of the tunnel wall is avoided. .
Step two, transferring the gantry crane 500 onto the longitudinal beam 202 of the guide beam 200 by using a first gantry crane transfer truck on the first conveyor Liang Zhuanlie;
specifically, the first gantry transfer vehicle formed by the first beam-carrying trolley 401 and the gantry crane bracket 700 moves between the guide beams 203 of the guide beam 200, the lifting part 703 of the gantry crane bracket 700 is lifted, so as to drive the support arm 702 to lift, the bottom end of the gantry crane 500 just reaches the height of the guide beam 203, at this time, the support arm 702 is rotated, so that the length direction of the gantry crane 500 is perpendicular to the length direction of the first conveyor Liang Zhuanlie, and the gantry crane 500 can easily drop onto the guide beam 203 and can travel longitudinally through its own travelling mechanism.
After the gantry crane 500 is transferred onto the longitudinal beam 202 of the guide beam 200, the gantry crane support 700 is detached from the first beam carrying trolley 401, the gantry crane support 700 needs to be lifted and moved to a side far away from the beam changing piece by the gantry crane 500 to achieve avoidance, and the guide beam transfer trolley 100 also needs to avoid, so that the gantry crane support 700 is connected with the guide beam transfer trolley 100.
Hoisting the guide beam transfer trolley 100 by using the gantry crane 500 to span the cross beam 201 and moving the guide beam transfer trolley 100 to one side of the guide beam 200, which is close to the second transport Liang Zhuanlie; the disassembled old beam is hoisted to the first conveyor Liang Zhuanlie by utilizing two gantry cranes 500 to cooperate with two first beam carrying trolleys 401 on the first conveyor Liang Zhuanlie;
Because a construction space is required to be provided for the lifting and the moving of the old beam to be dismounted, the synchronous avoidance of the gantry crane bracket 700 and the guide beam transfer trolley 100 to the old beam to be dismounted can be realized by moving the guide beam transfer trolley 100. In the process of removing the beam pieces, the old beam of the frame hole site to be replaced is lifted by the two gantry cranes 500 and drives the beam pieces to move towards the direction of the first carrying Liang Zhuanlie, two first beam carrying trolleys 401 on the first carrying trolley Liang Zhuanlie 301 move to a position close to the guide beam 200, the gantry cranes 500 close to the first carrying trolley Liang Zhuanlie 301 lower the end parts of the beam pieces, so that the beam pieces are supported on the first beam carrying trolleys 401 far away from the guide beam 200, the first beam carrying trolleys 401 and the gantry cranes 500 far away from the first carrying trolley Liang Zhuanlie move synchronously until the gantry cranes 500 far away from the first carrying trolley Liang Zhuanlie move to a position close to the end parts of the guide beam 200, the beam pieces are lowered, the other ends of the beam pieces are supported on the first beam carrying trolleys 401 close to the guide beam 200, and after the two first beam carrying trolleys 401 drive the beam pieces to move to the designated positions on the first carrying trolley Liang Zhuanlie, the first carrying trolley Liang Zhuanlie drives the beam pieces to move to the beam piece placement area.
Step four, lifting the guide beam transfer trolley 100 and the combination of the gantry crane bracket 700 by using the gantry crane 500, crossing the cross beam 201 and moving to one side of the guide beam 200 close to the first conveying Liang Zhuanlie; the new beam to be replaced is hoisted to the place to be replaced by using the gantry crane 500 in combination with the two second beam-carrying trolleys 402 on the second conveyor Liang Zhuanlie.
Because a construction space is required to be provided for the hoisting and the movement of the new beam to be installed, the synchronous avoidance of the gantry crane bracket 700 and the guide beam transfer trolley 100 to the new beam to be installed can be realized by moving the guide beam transfer trolley 100. When a new beam is installed, the beam for replacement is placed on two second beam-carrying trolleys 402 on a second transport line, the two second beam-carrying trolleys 402 are supported at the two ends of the beam, two gantry cranes 500 move to the end of the guide beam 200 near the second carrier Liang Zhuanlie, the end of the beam near the guide beam 200 is lifted by the gantry cranes 500 far from the second carrier Liang Zhuanlie 302, and the beam is moved towards the first carrier Liang Zhuanlie in synchronization with the second beam-carrying trolleys 402 far from the guide beam 200 until the second beam-carrying trolleys 402 move to a position near the end of the guide beam 200, the gantry cranes 500 near the second carrier Liang Zhuanlie move the beam-carrying trolleys 500 on the guide beam 200, and the lifted beam is erected at the place to be replaced.
Step five, the guide beam transfer trolley 100 drives the guide beam 200 and the gantry crane 500 positioned at the top of the guide beam 200 to move to the position above the next frame replacement hole, the first conveyor Liang Zhuanlie is used for conveying the removed old beam to a designated position and then returning the removed old beam to one side of the guide beam 200, the second conveyor Liang Zhuanlie is used for conveying a new beam to be replaced to the other side of the guide beam 200, and the step five is repeated for a plurality of times according to practical conditions. The actual operation in the fifth step is to repeat the third step and the fourth step, which will not be described in detail herein. It should be noted that, in this process, the guide beam 200 needs to be erected on the guide beam transfer car 100 again, and the description is omitted herein because the gantry crane bracket 700 is connected to the top of the guide beam transfer car 100, so that the lifting of the guide beam 200 by the guide beam transfer car 100 is not affected.
Step six, the first transporting Liang Zhuanlie drives the removed old beam to move to a designated position, the two gantry cranes 500 move towards the direction of the second transporting Liang Zhuanlie, the gantry crane support 700 is detached from the guide beam transporting truck 100, the gantry crane support 700 is transported by the gantry crane 500 and is connected with the second beam carrying trolley 402 to form a second gantry crane transporting truck, the gantry crane 500 is transported to the second transporting Liang Zhuanlie by the second gantry crane transporting truck, and the second transporting Liang Zhuanlie drives the gantry crane 500 to move to the designated position.
It should be added that in the fifth step, the guide beam 200 may encounter a situation of passing through a tunnel or a railway curve during the moving process, and the width of the guide beam 200 is larger than the width of the whole hole beam surface to be replaced, so if the guide beam 200 is not shrunk, the problem of exceeding the railway width limit may occur, and when the guide beam 200 needs to be shrunk, the gantry crane 500 should be first lowered onto the second transport Liang Zhuanlie in advance, which specifically includes the following steps: the two gantry cranes 500 move towards the second conveying Liang Zhuanlie and the gantry crane support 700 is detached from the guide beam conveying trolley 100, the gantry crane support 700 is conveyed through the gantry crane 500 and is connected with the second beam carrying trolley 402 to form a second gantry crane conveying trolley, and then the gantry crane 500 is conveyed to the second conveying Liang Zhuanlie through the second gantry crane conveying trolley. When the first carriage Liang Zhuanlie, the guide beam 200 and the second carriage Liang Zhuanlie are moved into position, that is, the guide beam 200 is positioned at the next frame hole to be replaced, the guide beam 200 is lowered, the gantry 500 is replaced on the guide beam 200 through the second gantry transfer vehicle, the gantry support 700 is detached from the second beam carriage 402, and the gantry support 700 is connected with the guide beam transfer vehicle 100 again.
And after the construction is finished, welding the cut steel rail, filling the railway ballast, tamping the railway ballast by using a tamping car, recovering the contact net, and finishing the bridge replacement work.
In the beam replacement process, after the old beam is disassembled, the first transporting Liang Zhuanlie is capable of transporting the old beam to the bridge placing area, and returning to one side of the guide beam 200 to wait for the next transportation. Similarly, when the gantry crane 500 lifts the new beam to be replaced on the second transport Liang Zhuanlie, the second transport Liang Zhuanlie can move to the new beam stacking area to take the new beam and return to the other side of the guide beam 200. During this time, the gantry crane 500 completes the assembly of the bridge and performs the replacement of the next bridge. The whole operation process can be synchronously completed, the working efficiency is increased, the skylight point time operation is effectively utilized, the application range is wide, the beam replacement construction under various terrain environment conditions can be realized, and the method has irreplaceable advantages for the beam replacement construction under high piers, deep valleys and under-bridge water environments; the requirements on the preparation conditions in the early stage of the construction site are less, and the influence on the existing line is small; the new beam has completed all the assembly procedures in the beam field, has little pollution to the construction site in the beam replacement process, and accords with the green and environment-friendly construction concept.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
