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 walking on a guide beam. 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] During the transportation of the guide beam, in order to achieve 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. The guide beam transfer vehicle includes a vehicle body, and the vehicle body is provided with a lower walking mechanism for walking on the bridge and a beam support platform arranged on the guide beam transfer vehicle, and the guide beam is placed on the beam support platform.

[0010] In order to avoid affecting the movement and construction of the gantry crane on the guide beam, the guide beam transfer vehicle should move to an idle area after transporting the guide beam to the right place. Therefore, when the guide beam is in place, the guide beam transfer vehicle moves on the bridge to be demolished in the direction away from the gantry crane until it moves to the end of the guide beam transfer vehicle. However, since the cross beam of the guide beam prevents the guide beam transfer vehicle from continuing to move forward, the guide beam transfer vehicle needs to be lifted to cross the cross beam, which is inconvenient to use; and after the bridge to be demolished is demolished, since the lower walking mechanism has no support surface, it cannot move by itself, and the guide beam transfer vehicle needs to be lifted to the other end of the guide beam by the gantry crane, which affects work efficiency.

[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 5 As 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 Figure 6 , Figure 7 and Figure 8As shown, an embodiment of the present application provides a guide beam transfer vehicle that can walk on a guide beam, the guide beam transfer vehicle 1 includes a vehicle body 6, on which are provided a lower walking mechanism 3, an upper walking mechanism 4 and a beam support platform 5, the lower walking mechanism 3 is arranged at the bottom of the vehicle body 6, and is used for walking on the bearing surface; the beam support platform 5 is used for placing the guide beam 2 in a retracted state; the upper walking mechanism 4 is arranged above the beam support platform 5, and is used for walking on the top surface of the guide beam 2 in an expanded state, the lower walking mechanism 3 can move in a vertical direction relative to the upper walking mechanism 4, and the moving range of the lower walking mechanism 3 is greater than the height of the crossbeam 21 of the guide beam 2.

[0040] In the present application, the vehicle body 6 can be driven to move on the bearing surface by the lower walking mechanism 3, and the vehicle body 6 is provided with an upper walking mechanism 4. When the bridge is dismantled, the upper walking mechanism 4 can be used to move on the guide beam 2, thereby driving the vehicle body 6 to move on the guide beam 2, so that the vehicle body 6 does not need to rely on other equipment during the movement process, thereby avoiding affecting the normal construction of other equipment and increasing work efficiency. Figure 7 As shown, the lower walking mechanism 3 can be raised and lowered relative to the upper walking mechanism 4, and the moving range of the lower walking mechanism 3 is greater than the height of the crossbeam 21 of the guide beam 2. When the vehicle body 6 moves to the crossbeam 21 of the guide beam 2, the lower walking mechanism 3 rises until the horizontal height of the bottom of the lower walking mechanism 3 is higher than the horizontal height of the top surface of the crossbeam 21. The vehicle body 6 is driven by the upper walking mechanism 4 to cross the crossbeam 21, thereby increasing the convenience of use.

[0041] like Figure 8 As shown, the support beam platform 5 of the present application includes two support plates 51 symmetrically arranged on the vehicle body 6, and the positions of the two support plates 51 correspond to the positions of the two longitudinal beams 22 of the guide beam 2 in the retracted state, respectively, and the two longitudinal beams 22 of the guide beam 2 are supported on the top 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. And the distance between the ends of the two support plates 51 is smaller than the distance between 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, and 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 transport vehicle in its transverse direction during the movement.

[0042] The lower walking mechanism 3 includes a bottom plate 31 arranged at the bottom of the vehicle body 6 and a roller 32 arranged at the bottom of the bottom plate 31, wherein there are multiple rollers 32, which are evenly distributed at the bottom of the bottom plate 31, and at least one of the rollers 32 is connected to a motor, and the motor drives the roller 32 to rotate, thereby driving the vehicle body 6 to walk, realizing automatic control and saving labor costs. The vehicle body 6 is supported by the bottom plate 31 to increase the stability of the vehicle body 6 during walking. Preferably, the support plate 51 is arranged on the top of the bottom plate 31, and the bottom plate 31 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 heavy guide beam 2, and at the same time, effectively increase the service life of the support plate 51.

[0043] Combination Figure 8 and Fig. 9 As shown, the upper walking mechanism 4 includes a base 41 sleeved on the outer periphery of the vehicle body 6 and a suspension arm 42 symmetrically arranged on both sides of the base 41. The ends of the two suspension arms 42 are provided with a running wheel bracket 43. The running wheel bracket 43 is provided with a running wheel 44 for running on the unfolded guide beam 2. The suspension arm 42 is provided with a driving motor 45, and the driving motor 45 is connected to the running wheel 44 through a wheel group transmission. Specifically, a driving pulley 46 is provided on the output shaft of the driving motor 45, and a driven pulley 47 is provided on the running wheel 44. The wheel group includes a plurality of guide pulleys 48. The belt is sleeved on the outer periphery of the driving pulley 46 and the driven pulley 47, and the guide pulley 48 has the effect of tightening the belt, thereby increasing the transmission effect of the belt. This design method can drive two or more running wheels 44 to walk synchronously through a driving motor 45, thereby increasing the stability during the walking process.

[0044] In some embodiments, the base 41 is rotatably arranged on the vehicle body 6 in the horizontal direction, and the bottom of the suspension arm 42 is provided with a connecting rod 49 for connecting with the longitudinal beam 22 of the guide beam 2. When in use, the guide beam 2 is connected through the connecting rod 49, and the longitudinal beam 22 is driven to rotate by the rotation of the suspension arm 42, thereby completing the expansion or retraction process of the guide beam 2. Among them, the suspension arm 42 can be rotated by an external force, and a driving device for driving the base 41 to rotate can also be arranged on the vehicle body 6. Preferably, the driving device includes a motor arranged on the vehicle body 6, the output shaft of the motor is arranged vertically upward, the base 41 is arranged on the output shaft of the motor, and the suspension arm 42 is driven to rotate by the rotation of the motor, thereby realizing the contraction or expansion of the guide beam 2. Specifically, the base 41 is arranged on the top of the vehicle body 6, and the vehicle body 6 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 base 41. This design method can drive the longitudinal beam 22 to rotate through the upper walking mechanism 4, thereby controlling the expansion or retraction of the guide beam 2, thereby increasing the convenience of use.

[0045] Further optimized, the connecting rod 49 can be extended and retracted along its own length direction. There are many ways to set the connecting rod 49, such as the inner and outer tube setting method, that is, an outer tube is set at the bottom of the boom 42, 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 connecting rod 49 is not limited, as long as its telescopic performance can be met.

[0046] There are also many ways to connect the connecting rod 49 to the guide beam 2: for example, a connecting plate can be set on the inner side of the longitudinal beam 22, and a connecting hole can be set on the connecting plate, and the connecting rod 49 matches the connecting hole. The matching here means that the connecting rod 49 can be inserted into the connecting hole. Among them, the connecting plate can be hidden in the longitudinal beam 22. Specifically, a groove can be set on the longitudinal beam 22, and the connecting plate can be rotated or telescopically set in the groove. When in use, the connecting plate extends out of the longitudinal beam 22, and the connecting rod 49 extends downward until it is inserted into the connecting hole and fixed. Among them, a through hole can be set on the connecting plate, and a plug hole can be set at a position corresponding to the through hole on the connecting rod 49. The pin shaft passes through the through hole and the plug hole in sequence to complete the limit. The connecting rod 49 of this design adopts a sliding setting method to facilitate positioning. A screw hole can also be set on the top of the longitudinal beam 22, and the bottom of the connecting rod 49 is set as a screw rod matching the screw hole, and the top of the connecting rod 49 is rotatably set with the boom 42, 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 49 and the longitudinal beam 22, and the specific setting method is not limited, as long as the boom 42 can drive the longitudinal beam 22 to rotate and the two are detachably connected.

[0047] In other embodiments, in combination Figure 8 and Fig.10As shown, the outer periphery of the car body 6 is provided with a movable sleeve 61 sliding in the vertical direction, and the base 41 is rotatably provided on the outer periphery of the movable sleeve 61. Through this design method, the lower traveling mechanism 3 can move in the vertical direction relative to the upper traveling mechanism 4. Further optimized, a slider is provided on the car body 6 in the vertical direction, and a slide groove matching the slider is provided on the inner wall of the movable sleeve 61, and the slider and the slide groove play a guiding role in the movement of the movable sleeve 61. Among them, a first telescopic device can be provided between the base 41 and the support beam platform 5, or a second telescopic device can be provided between the base 41 and the lower traveling mechanism 3. The telescopic movement of the car body 6 and the movable sleeve 61 is driven by the telescopic movement of the first telescopic device or the second telescopic device, and at the same time, the position of the movable sleeve 61 can be limited after adjustment. And the first telescopic device and the second telescopic device can be set in a variety of ways, such as using an electric push rod, a hydraulic cylinder or a cylinder. The base 41 can be rotated manually or driven by electricity. Specifically, a gear can be arranged in the horizontal direction inside the base 41, and the inner wall of the gear is rotatably arranged on the movable sleeve 61, and the upper and lower sides of the gear are connected to the inner wall of the base 41. A motor is arranged on the side of the movable sleeve 61, and the output shaft of the motor is arranged downward, and a driving wheel meshing with the gear is arranged at the end of the motor output shaft, and the gear is driven to rotate by the rotation of the driving wheel, and then the base 41 is driven to rotate, and the driving wheel and the gear work together to achieve a deceleration effect.

[0048] This design facilitates the installation of the guide beam 2. When the guide beam 2 is erected, the arm 42 is rotated so that the connection rod 49 corresponds to the position of the connection plate on the guide beam 2, and the position of the movable sleeve 61 is adjusted downward to reduce the height of the connection rod 49 in the vertical direction, and then the connection rod 49 is stretched so that the connection rod 49 is connected to the connection plate. The movable sleeve 61 is adjusted upward to drive the guide beam 2 to move upward through the connection rod 49 until it reaches the height of the joist platform 5, and the arm 42 is rotated to shrink the guide beam 2, and the guide beam 2 is lowered onto the joist platform 5 to be transported to the designated position.

[0049] When lowering the guide beam 2, firstly, the movable sleeve 61 is adjusted upwards, so that the connecting rod 49 drives the guide beam 2 to move upwards a certain distance, and then the guide beam 2 is separated from the beam support platform 5, and the suspension arm 42 is rotated to unfold the guide beam 2. In this process, the friction between the guide beam 2 and the beam support platform 5 is avoided, the driving force for rotating the suspension arm 42 is reduced, and the service life is increased. When the guide beam 2 is fully unfolded, the movable sleeve 61 is adjusted downwards to lower the guide beam 2.

[0050] In other embodiments, another design method can also be adopted to make the lower walking mechanism 3 move in the vertical direction relative to the upper walking mechanism 4. Specifically, the car body 6 adopts a split design method, the car body 6 includes a first car body 6 and a second car body 6, the lower walking mechanism 3 and the joist platform 5 are arranged on the first car body 6, the upper walking mechanism 4 is arranged on the second car body 6, the second car body 6 is lifted relative to the first car body 6, and the second car body 6 is connected with a driving device for driving it to lift. Further optimized, the driving device is a telescopic member vertically arranged on the first car body 6, and the second car body 6 is arranged on the top of the telescopic member. Among them, a cavity can be arranged on the top of the first car body 6, the telescopic member is arranged in the cavity, and the top of the telescopic member extends upward from the cavity for connecting with the second car body 6, and the position of the second car body 6 relative to the first car body 6 in the vertical direction is changed by the telescopic member. Preferably, the telescopic member can be an electric push rod, a cylinder or a hydraulic cylinder, so that after the second car body 6 is lifted to a suitable position, the telescopic member can play a role in supporting the position of the first car body 6 and the second car body 6.
