Description

Technical Field

[0001] This application relates to the technical field of track construction equipment, and particularly to a transfer tooling for a ballastless track laying rail panel frame. Background Art

[0002] A ballastless track refers to a track structure that uses a monolithic foundation such as concrete or asphalt mixture to replace the ballast bed composed of loose gravel, also known as a ballastless track, which is an advanced track technology in the world today. Compared with a ballasted track, a ballastless track avoids ballast splashing, has good ride quality, good stability, a long service life, good durability, less maintenance work, and the train running speed can reach more than 350 kilometers per hour. Currently, when constructing a double-block ballastless track, the rail panel method is usually adopted, and the rail panel frame and the formwork system are reinforced and finely adjusted by means of top or support with rods.

[0003] When constructing the ballast bed slab, generally, the formwork of the ballast bed slab is installed first, and then the rail panel frame is installed and roughly adjusted and finely adjusted. After the rail panel is finely adjusted, concrete is quickly poured until it is shaped; after pouring, it is also necessary to use a large gantry crane to hoist and transfer the rail panel frame to the next section. According to the set length of the current ballast bed slab, it is generally necessary to have an interval of 100 meters; therefore, using a large gantry crane on site not only has the defect of inconvenient movement, but also has the problem that it is difficult to leave enough space for the gantry crane to move in actual construction. Therefore, it seriously restricts the construction efficiency of laying ballastless tracks on bridges and roads. Summary of the Utility Model

[0004] In order to improve the problem of low efficiency in the transfer of the rail panel frame relying on a gantry crane, this application provides a transfer tooling for a ballastless track laying rail panel frame.

[0005] A transfer tooling for a ballastless track laying rail panel frame provided by this application adopts the following technical solution:

[0006] A transfer tooling for a ballastless track laying rail panel frame includes:

[0007] A gantry, which has a hoisting module for hoisting the rail panel frame, and one side of the gantry along its traveling direction is provided with rollers, and the other side is provided with a first concave wheel;

[0008] A guide rail, which is arranged along the laying direction of the ballastless track and is used for the first concave wheel to travel;

[0009] A transport trolley, at the four corners of which there are second concave wheels, and the second concave wheels are in rolling fit with the rail, and the distance between two coaxial second concave wheels is adapted to the rail spacing.

[0010] Furthermore, at least two groups of telescopic brackets are arranged on the side of the transport trolley along its conveying direction, and the upper end surfaces of the telescopic brackets are flush with the upper end surface of the transport trolley.

[0011] Furthermore, the telescopic bracket includes:

[0012] An outer sleeve, fixedly connected to the side of the transport trolley and arranged along the axial direction of the second cam;

[0013] An inner insertion tube, inserted into the outer sleeve;

[0014] An end face flush structure is provided between the outer sleeve and the inner insertion tube.

[0015] Furthermore, the end face flush structure includes:

[0016] A long groove, opened on the upper end face of the outer sleeve and penetrating the wall thickness where the upper end face of the outer sleeve is located;

[0017] A stiffening rib, fixedly connected to the upper end face of the inner insertion tube, the stiffening rib is slidably arranged in the long groove, and the upper end face of the stiffening rib is flush with the upper end face of the outer sleeve.

[0018] Furthermore, the hoisting module includes:

[0019] Electric hoists, two of them are arranged on the top beam of the gantry;

[0020] A balance beam, suspended on the hoisting chains of the electric hoists and arranged along the walking direction of the gantry;

[0021] A spreader, arranged at the end of the balance beam and used for hoisting the rails on the track support frame, and the spreaders are arranged at both ends of the balance beam.

[0022] Furthermore, the spreader is set as a sling with a hook or a rail clamp.

[0023] Furthermore, a hub motor for driving two coaxial second cams to rotate is arranged on the transport trolley.

[0024] Furthermore, the hub motor is controlled and connected to a handheld remote control.

[0025] In summary, the beneficial technical effects of the present application are:

[0026] When carrying out the transfer operation of the track panel support, first lift the track panel support steadily onto the gantry with the aid of the hoisting module. The construction workers push the gantry. Due to the arrangement of the rollers on one side and the first concave wheels on the other side of the gantry, the first concave wheels roll on the guide rail, which can ensure the traveling direction when the gantry moves. Then, when the gantry moves to the position where the transport trolley is located, release the hoisting of the track panel support by the hoisting module and place the track panel support steadily on the transport trolley. By means of the movement of the transport trolley on the rails of the other track panel supports that have not been disassembled and assembled, the disassembled and assembled track panel support can be transported to the next construction section. At this time, the gantry continues to carry out the demolition and hoisting operations of the next track panel support in the original construction section. Therefore, through the alternating operations of the gantry and the transport trolley, the space occupation of large-scale construction equipment on site can be greatly reduced, and it can be flexibly rotated in each construction section, which can greatly improve the turnover efficiency of the track panel support and thus improve the track-laying efficiency.

[0036] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0037] Embodiment 1:

[0038] An embodiment of the present application discloses a transfer tool for a track-laying gantry of a ballastless track. Refer to Figure 1 and Figure 2 , which includes:

[0039] A gantry 1, which has a hoisting module for hoisting the track-laying gantry 5. One side of the gantry 1 along its traveling direction is provided with rollers 11, and the other side is provided with first concave wheels 12;

[0040] A guide rail 13, which is arranged along the laying direction of the ballastless track and is used for the first concave wheel 12 to travel. Specifically, the guide rail 13 is set as an angle steel;

[0041] A transport trolley 2, at the four corners of which second concave wheels 21 are provided. The second concave wheels 21 are in rolling fit with the steel rails, and the distance between two coaxial second concave wheels 21 is adapted to the distance between the steel rails.

[0042] In this way, when carrying out the transfer operation of the track-laying gantry 5, the track-laying gantry 5 can be first hoisted onto the gantry 1 stably by means of the hoisting module. Then, the construction workers can push the gantry 1. Due to the arrangement of the rollers 11 on one side and the first concave wheels 12 on the other side of the gantry 1, the first concave wheels 12 roll on the guide rail 13, which can ensure the traveling direction of the gantry 1 when it walks. Then, when the gantry 1 walks to the position where the transport trolley 2 is located, the hoisting of the track-laying gantry 5 by the hoisting module can be released, and the track-laying gantry 5 can be stably placed on the transport trolley 2. By means of the walking of the transport trolley 2 on the steel rails of the remaining track-laying gantries 5 that have not been disassembled and assembled, the disassembled and assembled track-laying gantry 5 can be transported to the next construction section. At this time, the gantry 1 continues to carry out the demolition and hoisting operations of the next track-laying gantry 5 in the original construction section. Therefore, through the alternating operations of the gantry 1 and the transport trolley 2, the space occupation of large-scale construction equipment on the site can be greatly reduced, and it can be flexibly rotated in each construction section, which can greatly improve the turnover efficiency of the track-laying gantry 5 and thus improve the track-laying efficiency.

[0043] Specifically, in order to further reduce the size of the transport trolley 2 while ensuring the stable support of the track-laying gantry 5, refer to Figure 1 and Figure 3 , it is further set that: at least two groups of telescopic brackets 3 are arranged on the side of the transport trolley 2 along its conveying direction, and the upper end surfaces of the telescopic brackets 3 are flush with the upper end surface of the transport trolley 2.

[0044] The telescopic bracket 3 includes:

[0045] An outer sleeve 31, which is fixedly connected to the side of the transport trolley 2 and is arranged along the axis of the second concave wheel 21. A anti-disengagement groove 312 is opened on the side of the outer sleeve 31 along its length direction;

[0046] The inner insertion tube 32 is inserted into the outer sleeve tube 31 in a plug-in manner, and an anti-detachment nut 322 is screwed on the outer wall of the inner insertion tube 32 and penetrates through the anti-detachment groove 312. The anti-detachment nut 322 can slide in the anti-detachment groove 312 to prevent the inner insertion tube 32 from being pulled out when it is pulled;

[0047] Both the outer sleeve tube 31 and the inner insertion tube 32 are made of square tubes, and an end face flush structure is provided between the outer sleeve tube 31 and the inner insertion tube 32.

[0048] The end face flush structure includes:

[0049] A long groove 311 is opened on the upper end face of the outer sleeve tube 31 and penetrates through the wall thickness where the upper end face of the outer sleeve tube 31 is located;

[0050] Reinforcing ribs 321 are fixedly connected to the upper end face of the inner insertion tube 32. The reinforcing ribs 321 are slidably arranged in the long groove 311, and the upper end face of the reinforcing ribs 321 is flush with the upper end face of the outer sleeve tube 31. Specifically, when set, two parallel reinforcing ribs 321 are provided, and the two reinforcing ribs 321 are respectively attached to both sides of the long groove 311.

[0051] In this way, when the transport trolley 2 transports the track support frame 5, the telescopic bracket 3 can be unfolded. Specifically, the inner insertion tube 32 is pulled out from the outer sleeve tube 31, and the inner insertion tube 32 is not completely pulled out of the outer sleeve tube 31. At this time, the total length of the telescopic bracket 3 increases, that is, the overall width of the transport trolley 2 increases, so that the contact surface between the transport trolley 2 and the track support frame 5 increases, and the stability of the track support frame 5 on the transport trolley 2 can be improved; and at this time, the arrangement of the reinforcing ribs 321 can ensure that the upper end face of the inner insertion tube 32 extending out of the outer sleeve tube 31 is always flush with the upper end faces of the outer sleeve tube 31 and the transport trolley 2, which can further reduce the probability of the track support frame 5 shaking on the transport trolley 2 and improve the safety of construction workers when transferring the track support frame 5.

[0052] In addition, the above-mentioned hoisting module includes:

[0053] Electric hoists 41, two of them are arranged on the top beam of the gantry 1 and are spaced apart by a distance not less than the standard rail spacing, so that the lifting points of the hoisting module on the track support frame 5 are as far apart as possible, reducing the probability of shaking during hoisting;

[0054] A balance beam 42 is suspended on the lifting chain of the electric hoist 41 and is arranged along the walking direction of the gantry 1. The lifting chain of the electric hoist 41 is connected to the middle of the upper end face of the balance beam 42 in the length direction;

[0055] A lifting tool 43 is arranged at the end of the balance beam 42 and is used for hoisting the rails on the track support frame 5. Lifting tools 43 are arranged on the lower end faces of both ends of the balance beam 42; the lifting tool 43 is set as a lifting chain with a hook or a rail clamp.

[0056] In this way, when hoisting the track panel rack 5, four lifting tools 43 can be used to lift four symmetric points on the track panel rack 5, which can ensure the stability of the track panel rack 5 when being hoisted and the stability during the transportation process, and reduce the probability of the track panel rack 5 shaking on the gantry 1.

[0057] Embodiment 2:

[0058] The embodiment of the present application discloses a transfer tool for a ballastless track laying track panel rack. The difference between this embodiment and Embodiment 1 is as follows:

[0059] The transport trolley 2 is provided with hub motors for driving two coaxial second concave wheels 21 to rotate, and the hub motors are controlled and connected with a handheld remote control. Thus, the construction personnel can control the walking, starting and stopping of the transport trolley 2 through the handheld remote control, avoiding the safety risks existing when the construction personnel manually push the transport trolley 2 and the track panel rack 5, saving the physical strength of the construction personnel, and thus improving the construction efficiency to a certain extent.

[0060] The implementation principle of a transfer tool for a ballastless track laying track panel rack in the embodiment of the present application is as follows:

[0061] When performing the transfer operation of the track panel rack 5, first hoist the track panel rack 5 onto the gantry 1 stably by means of the hoisting module. The construction personnel push the gantry 1. Due to the arrangement of the rollers 11 on one side and the first concave wheels 12 on the other side of the gantry 1, the first concave wheels 12 roll on the guide rail 13, which can ensure the traveling direction of the gantry 1 when walking. Then, when the gantry 1 walks to the position where the transport trolley 2 is located, release the hoisting of the track panel rack 5 by the hoisting module and place the track panel rack 5 stably on the transport trolley 2. By means of the walking of the transport trolley 2 on the rails of the remaining track panel racks 5 that have not been disassembled and assembled, the disassembled and assembled track panel rack 5 can be transported to the next construction section. At this time, the gantry 1 continues to perform the disassembly and hoisting operations of the next track panel rack 5 in the original construction section. Therefore, through the alternating operation of the gantry 1 and the transport trolley 2, the space occupation of large-scale construction equipment on site can be greatly reduced, and it can be flexibly rotated in each construction section, which can greatly improve the turnover efficiency of the track panel rack 5 and thus improve the track laying efficiency.
