Description

Technical Field

[0001] The invention relates to the technical field of bridge frame replacement equipment, and in particular to a guide beam transfer vehicle capable of driving a guide beam to be laterally expanded or retracted. Background Art

[0002] With the increase in the operating time of railways and highways in my country, the problem of bridge aging has an increasingly prominent impact on the safety of existing lines (already built lines). Some bridges that were built not long ago have to be replaced because their strength or stiffness cannot meet the requirements due to the continuous speed increase of existing lines, especially the main trunk lines, and the need to pass heavy-load trains. Due to the poor manufacturing and installation quality of some bridges, some diseased bridges are also produced every year.

[0003] In addition, my country used a large number of steel beams in the construction of railways in the past. The service life of these steel beams is significantly lower than that of concrete beams, and the maintenance workload of steel beams is very large. In some places, maintenance is simply impossible, which also causes some steel beams to need to be replaced before they reach their strength life. Therefore, it is urgent to study one or several safe and reliable methods for replacing existing railway bridges for different bridge forms.

[0004] At present, the existing railway line bridge replacement methods in my country include fully closed existing line bridge replacement method and intermittent closed existing line bridge replacement method.

[0005] The idea of ​​fully enclosed beam replacement is to build a temporary line or bridge near the existing railway bridge; the train passes on the temporary line or bridge, and the bridge is mainly replaced by a bridge-building machine. This operation mode does not need to interrupt traffic and is suitable for bridges in rivers or valleys, but it requires the construction of a temporary line or bridge, and the line needs to be restored after the replacement, which is costly and time-consuming. When the train passes the temporary line (temporary bridge), the speed must be limited. When the temporary line is connected to the main line and the main line is connected to the main line, point construction is required. At the same time, the line is frequently disturbed, causing instability in the roadbed and ballast bed. Therefore, the speed limit time is long, which has a great impact on the punctual operation of the train; the construction and removal of the temporary line has a great impact on the environment.

[0006] The idea of ​​intermittent closure for beam replacement is to adjust the train operation diagram or the gap between train operations and use gantry cranes or bracket transverse movement to implement bridge replacement operations. This operation mode does not require the construction of a bypass line, is low-cost, and has no environmental pollution; the preparation time is short, and the bridge replacement work can be carried out in a shorter time; the disturbance to the existing line is small, and normal operation can be restored in a shorter time after the replacement is completed. The preparation work is carried out offline and does not interfere with the existing line, but it cannot be applied to bridges in valleys or above rivers. Since there is no bypass line for vehicles to bypass when intermittently closing the existing line for bridge replacement, the safety and reliability of the equipment and the length of the closure time become the top priorities of this plan.

[0007] In order to solve the above problems, it is urgent to propose a new set of railway beam bridge replacement construction technology and equipment that can be applied to various pier heights or terrain and topography under the bridge, provide new ideas and methods for bridge replacement projects, and ensure that the overall replacement construction of whole-hole simply supported beams, rails and switches can be completed safely and efficiently within the "window point" under the premise of minimum interference to the original line equipment.

[0008] One solution is to set up a guide beam at the railway beam replacement site, and the gantry crane will be used to dismantle and replace the bridge on the guide beam. During the work, the gantry crane and the new beam are first transported to the construction site by two beam transport trains. At the same time, the guide beam is moved to the bridge replacement site by the guide beam transfer vehicle, and the two beam transport trains are on both sides of the guide beam. After the guide beam is in place, the gantry hanger is installed on the guide beam through the gantry bracket, and the old beam is dismantled and installed and the new beam is installed on the guide beam by the gantry crane to complete the beam replacement process. This beam replacement method has little impact on existing lines and has a wide range of applications. It can realize beam replacement construction under various terrain and environmental conditions, especially for beam replacement construction in high piers, deep valleys and water environments under bridges. It has irreplaceable advantages.

[0009] However, in order to realize the overall replacement of the whole-hole beam, the width of the guide beam is generally greater than the width of the bridge beam surface, which results in a larger width of the guide beam. During transportation, when passing through a curved section, the two ends of the guide beam deviate from the center line, which is prone to over-limit phenomenon, affecting the normal transportation of the guide beam. Therefore, the guide beam can be folded, that is, the crossbeam and longitudinal beam of the guide beam are hinged. In the transportation state, the guide beam can be retracted to reduce the lateral length of the guide beam. After the guide beam is transported to the work site, the guide beam is transported to the work position by a guide beam transfer vehicle. After the guide beam moves to the work position, it is unfolded to carry out the next step of beam replacement. However, the traditional guide beam transfer vehicle can only play the role of transporting the guide beam. When the guide beam is transported to the work position, the guide beam needs to be erected, and then other devices are used to drive the longitudinal beam and the crossbeam to rotate relative to each other to complete the unfolding or retraction of the guide beam, which is inconvenient to use. Summary of the invention

[0036] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0037] Combination Figures 1 to 5As shown in the figure, the specific replacement process of the existing bridge is as follows:

[0038] The gantry crane is placed on the first beam transport train, and the replacement bridge is placed on the second beam transport train, and the guide beam 2 is driven by the guide beam transfer vehicle 1. Figure 1 As shown, the guide beam transport vehicle 1 drives the guide beam 2 to move to the top of the beam to be replaced, and the guide beam 2 falls into place. The first beam transport train and the second beam transport train are respectively transported to the two sides of the bridge to be replaced. Figure 2 As shown, after the guide beam 2 is completely in place, the guide beam transfer vehicle 1 moves to the side of the guide beam 2 close to the second beam transport train, and the gantry crane transport vehicle at the bottom of the gantry crane drives the gantry crane to move on the first beam transport train until it moves to the end position of the guide beam 2, and then the gantry crane support is placed on the guide beam 2. Figure 3 As shown, the gantry crane moves on the guide beam 2 to complete the disassembly process of the bridge, and hoists the disassembled bridge onto the first beam transport train, which transports it to the designated location. Figure 4 and Figure 5 As shown, at this time, the guide beam transfer vehicle 1 moves to the end of the guide beam 2 close to the first beam transport train, and the replacement bridge on the second beam transport train is hoisted to the replacement position by the gantry crane to complete the installation of the bridge.

[0039] Combination Figures 6 to 10 As shown, the embodiment of the present application provides a guide beam transfer vehicle that can drive the guide beam to be laterally expanded or retracted. The guide beam transfer vehicle 1 includes a vehicle body 24 for being arranged between two longitudinal beams 22 of the guide beam 2. The size of the vehicle body 24 in the width direction of the guide beam 2 is smaller than the distance between the two longitudinal beams 22 of the guide beam 2 in the retracted state, so as to avoid the vehicle body 24 affecting the retraction of the guide beam 2. Fig.10 As shown, the car body 24 is provided with a lower walking mechanism 4 for walking on the bearing surface and a supporting mechanism 5 for placing the guide beam 2, and the bearing surface here includes the contact surface between the car body 24 and the first beam transport train and the second beam transport train and the walking surface of the bridge. The car body 24 is provided with a cantilever mechanism 6 for rotating in the horizontal direction, and the cantilever mechanism 6 is used to connect with the longitudinal beam 22 of the guide beam 2. Preferably, the car body 24 is set in a columnar shape to reduce the volume of the car body 24 and facilitate the rotation connection with the cantilever mechanism 6.

[0040] Combination Figures 6 to 9 As shown, the present application is provided with a cantilever mechanism 6 on the vehicle body 24, wherein the cantilever mechanism 6 can rotate relative to the vehicle body 24 under the action of an external force or its own driving device, so that the guide beam 2 transport vehicle 1 can drive the guide beam 2 to expand or retract through the cantilever mechanism 6 on the basis of being able to transport the guide beam 2, thereby increasing the convenience of use.

[0041] like Fig.10As shown, the support mechanism 5 includes support plates 51 arranged on both sides of the vehicle body 24, and the positions of the support plates 51 correspond to the positions of the two longitudinal beams 22 of the guide beam 2 in the retracted state, and the two longitudinal beams 22 of the guide beam 2 are supported on the tops of the two support plates 51 respectively. The correspondence here means that when the guide beam 2 is in the retracted state, the two longitudinal beams 22 of the guide beam 2 can be placed on the support plates 51. The distance between the ends of the two support plates 51 is smaller than the distance between the inner sides of the two longitudinal beams 22 of the guide beam 2 in the expanded state, so as to avoid the support plates 51 affecting the lowering of the guide beam 2, and the distance between the ends of the two support plates 51 is larger than the distance between the inner sides of the two longitudinal beams 22 of the guide beam 2 in the retracted state and smaller than the distance between the outer sides of the two longitudinal beams 22 of the guide beam 2 in the retracted state, so that the support plates 51 can play the role of supporting the guide beam 2. At the same time, the two ends of the support plates 51 will not extend out of the two sides of the longitudinal beam 2, so as to reduce the distance of the guide beam 2 in the lateral direction during the movement of the transport vehicle 1.

[0042] The lower walking mechanism 4 includes a base 41 arranged at the bottom of the vehicle body 24 and a roller 42 arranged at the bottom of the base 41, wherein there are multiple rollers 42, which are evenly distributed at the bottom of the base 41, and at least one of the rollers 42 is connected to a motor, and the motor drives the roller 42 to rotate, thereby driving the vehicle body 24 to walk, realizing automatic control, saving labor costs, and supporting the vehicle body 24 through the base 41, thereby increasing the stability of the vehicle body 24 during walking. Preferably, a support plate 51 is arranged on the top of the base 41, and the base 41 provides support for the support plate 51, thereby increasing the bearing capacity of the support plate 51, so that the support plate 51 can bear the heavier guide beam 2, and at the same time, effectively increase the service life of the support plate 51.

[0043] In some embodiments, the cantilever mechanism 6 of the present application includes a turntable 61 rotatably arranged on the car body 24 and a rotating arm 62 symmetrically arranged on the outer periphery of the turntable 61, and a connecting rod 63 for connecting to the longitudinal beam 22 of the guide beam 2 is provided at the bottom of the rotating arm 62. When in use, the guide beam 2 is connected by the connecting rod 63, and the adjustment process is completed by the rotation of the rotating arm 62. Among them, the rotating arm 62 can be rotated by an external force, and a driving device for driving the turntable 61 to rotate can also be arranged on the car body 24. Preferably, the driving device includes a motor arranged on the car body 24, the output shaft of the motor is arranged vertically upward, the turntable 61 is arranged on the output shaft of the motor, and the rotation of the motor drives the rotating arm 62 to rotate, thereby realizing the contraction or expansion of the guide beam 2. Specifically, the turntable 61 is arranged on the top of the car body 24, and the car body 24 is provided with an installation cavity, the motor is arranged in the installation cavity, and the output shaft of the motor extends upward from the installation cavity and is connected to the turntable 61.

[0044] Further optimized, the connecting rod 63 is a telescopic rod that can be extended and retracted along its own length direction. There are many ways to set the telescopic rod, such as the inner and outer tube setting method, that is, an outer tube is set at the bottom of the rotating arm 62, and an inner tube is set inside the outer tube, and the inner tube and the outer tube are slidably set. The inner tube is provided with a plurality of first positioning holes at intervals along its length direction, and the outer tube is provided with a plurality of second positioning holes at intervals along its length direction. When the inner tube is adjusted to a specified position, the positioning of the inner tube can be achieved by inserting a pin shaft, wherein the position of the inner tube can be adjusted manually. For another example, the inner tube and the outer tube are spirally connected, and the position of the inner tube relative to the outer tube in the vertical direction is changed by rotating the inner tube. It can be seen that the setting method of the telescopic rod is not limited, as long as its telescopic performance can be met.

[0045] There are also many ways to connect the connecting rod 63 with the guide beam 2: for example, a connecting plate 23 can be set on the inner side of the longitudinal beam 22, a connecting hole can be opened on the connecting plate 23, and the connecting rod 63 matches the connecting hole, and the matching here means that the connecting rod 63 can be inserted into the connecting hole. Among them, the connecting plate 23 can be hidden in the longitudinal beam 22, specifically, a groove can be set on the longitudinal beam 22, and the connecting plate 23 is rotatably or telescopically set in the groove. When in use, the connecting plate 23 extends out of the longitudinal beam 22, and the connecting rod 63 extends downward until it is inserted into the connecting hole and fixed. Among them, a through hole can be set on the connecting plate 23, and a plug hole can be set at a position corresponding to the through hole on the connecting rod 63, and the pin shaft passes through the through hole and the plug hole in sequence to complete the limit. The connecting rod 63 of this design adopts a sliding setting method, which is convenient for positioning. A screw hole can also be opened on the top of the longitudinal beam 22, and the bottom of the connecting rod 63 is set as a screw rod matching the screw hole, and the top of the connecting rod 63 is rotatably set with the rotating arm 62, and the connection is completed by the cooperation between the screw rod and the screw hole. It can be seen that there are many ways to connect the connecting rod 63 and the longitudinal beam 22, and the specific setting method is not limited, as long as the rotating arm 62 can drive the longitudinal beam 22 to rotate and the two are detachably connected.

[0046] In other embodiments, the outer periphery of the vehicle body 24 is provided with a movable sleeve 31 slidingly in the vertical direction, and the turntable 61 is rotatably arranged on the outer periphery of the movable sleeve 31. Further optimized, a slider 32 is provided on the vehicle body 24 in the vertical direction, and a slide groove matching the slider 32 is provided on the inner wall of the movable sleeve 31, and the slider 32 and the slide groove play a guiding role in the movement of the movable sleeve 31. Among them, a telescopic member can be provided between the movable sleeve 31 and the lower walking mechanism 4 or between the movable sleeve 31 and the supporting mechanism 5, and the telescopic member drives the vehicle body 24 and the movable sleeve 31 to slide relative to each other through the telescopic member, and at the same time, after adjustment, it can play the effect of limiting the position of the movable sleeve 31. And the telescopic member can be arranged in a variety of ways, such as using an electric push rod, a hydraulic cylinder or a cylinder. The turntable 61 can be rotated manually or by an electric drive. Specifically, a gear can be arranged in the horizontal direction inside the turntable 61, and the inner wall of the gear is rotatably arranged on the movable sleeve 31, and the upper and lower sides of the gear are connected to the inner wall of the turntable 61. A motor is arranged on the side of the movable sleeve 31, and the output shaft of the motor is arranged downwardly, and a driving wheel meshing with the gear is arranged at the end of the motor output shaft. The gear is rotated by the rotation of the driving wheel, and then the turntable 61 is driven to rotate, and the driving wheel and the gear work together to achieve a deceleration effect.

[0047] When the guide beam 2 is erected, the rotating arm 62 is rotated so that the connection rod 63 corresponds to the position of the connection plate 23 on the guide beam 2, the position of the movable sleeve 31 is adjusted downward, and the height of the connection rod 63 in the vertical direction is reduced, and the connection rod 63 is stretched so that the connection rod 63 is connected to the connection plate 23. The movable sleeve 31 is adjusted upward, and the guide beam 2 is driven to move upward through the connection rod 63 until it reaches the height of the support mechanism 5, and the rotating arm 62 is rotated to shrink the guide beam 2, and the guide beam 2 is lowered onto the support mechanism 5, and the guide beam 2 is transported to the designated position.

[0048] When lowering the guide beam 2, firstly, the movable sleeve 31 is adjusted upwards, so that the connecting rod 63 drives the guide beam 2 to move upwards a certain distance, and then the guide beam 2 is separated from the support mechanism 5, and the rotating arm 62 is rotated to unfold the guide beam 2. In this process, the friction between the guide beam 2 and the support mechanism 5 is avoided, the driving force for rotating the rotating arm 62 is reduced, and the service life is increased. When the guide beam 2 is fully unfolded, the movable sleeve 31 is adjusted downwards to put the guide beam 2 down.

[0049] Combination Fig.10 and Fig.11As shown, both sides of the rotating arm 62 of the present application are provided with an upper walking mechanism 7 for walking on the unfolded guide beam 2. Specifically, the upper walking mechanism 7 includes a driving motor 71 arranged on the rotating arm 62 and a running wheel bracket 72 arranged at the end of the rotating arm 62, and the running wheel bracket 72 is provided with a running wheel 73 for walking on the longitudinal beam 22 of the guide beam 2, and the driving motor 71 is connected to the running wheel 73 through a wheel group transmission. Specifically, a driving pulley 74 is provided on the output shaft of the driving motor 71, and a driven pulley 75 is provided on the running wheel 73. The wheel group includes a plurality of guide pulleys 76, and the belt is sleeved on the outer periphery of the driving pulley 74 and the driven pulley 75, and the belt is tightened through the guide pulley 76 to increase the transmission effect of the belt. This design method can drive two or more running wheels 73 to walk synchronously through a driving motor 71, thereby increasing the stability during the walking process.

[0050] After the bridge is dismantled, the vehicle body 24 can be driven by the upper traveling mechanism 7 to move on the guide beam 2, which increases the convenience of use. When the vehicle body 24 reaches the vicinity of the cross beam 21 of the guide beam 2, the movable sleeve 31 can be lowered, that is, the vehicle body 24 moves upward under the action of the reverse force until the level of the bottom of the lower traveling mechanism 4 is higher than the level of the top surface of the cross beam 21, and the vehicle body 24 is driven by the upper traveling mechanism 7 to cross the cross beam 21. No external equipment is needed, which increases the convenience of use and the moving efficiency.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
