Description

Technical Field

[0001] This utility model belongs to the field of track construction equipment, specifically relating to a track transport device for high-speed railway track slab construction. Background Technology

[0002] The construction of ballastless track slabs is generally divided into five sections: track assembly area, geotextile and elastic cushion layer installation area, bottom reinforcement binding area, track slab pouring area, and track curing area. The track slab construction involves multiple processes, requiring the use of gantry cranes to lift track panel fixtures, formwork, and sleepers. The gantry cranes used in construction traverse the box girder retaining wall and run on rails typically weighing 24 kg / m. These rails are fixed to the I-beams using fasteners. The I-beams are installed on the top of the B-wall and on the lower platform of the retaining wall.

[0003] During construction, in order to save on the amount of steel rails used, it is necessary to remove the traveling steel rails at the rear of the gantry crane's forward direction and move them to the rail assembly area at the front of the gantry crane's forward direction, and then install the steel rails in place so that the gantry crane can be used.

[0004] Currently, one method is manual handling, which has drawbacks such as significant safety hazards and low efficiency. Another method is to use a gantry crane to lift the rails, but this method is more complex because the gantry crane is large and the rails need to be moved over a wide range. Utility Model Content

[0005] The purpose of this invention is to provide a track transport device for high-speed railway track slab construction, in order to solve the problems of high safety hazards and low efficiency of manual rail handling, and the complexity of using gantry cranes to lift rails.

[0006] To solve the above-mentioned technical problems, this utility model provides a running track transport device for the construction of high-speed railway track slabs, including a transport vehicle body, and a number of bottom rollers are provided at the bottom of the transport vehicle body for moving the transport vehicle body on the protective wall.

[0007] The top of the transport vehicle body is the top of the frame, and a lifting assembly is installed on the top of the frame near the edge.

[0008] Furthermore, the lifting assembly includes a first boom and a second boom. The first boom is rotatably connected to the top of the vehicle frame; the second boom is rotatably connected to the first boom; and a lifting section is provided at the end of the second boom away from the first boom, which is used to lift and lower the track being lifted.

[0009] Furthermore, a lifting and moving track is provided on the second boom. The lifting and moving track is fixedly connected to the second boom and slidably connected to the lifting unit. The lifting unit is used to move the lifted track into or out of the main body of the transport vehicle.

[0010] Furthermore, a third boom is rotatably connected to the end of the second boom away from the first boom. The third boom is used to contact the ground and support the hoisting components being hoisted.

[0011] Furthermore, the top of the frame is provided with several lifting and mounting slots, which are located at the edges on both sides of the top of the frame. The lifting and mounting slots are used for detachably installing lifting components.

[0012] Furthermore, a boom fixing part is provided on the top of the frame, which is used to store and fix the unused first boom, second boom and third boom.

[0013] Furthermore, a hoisting motor is installed on the second boom, which is used to drive the hoisting unit to perform hoisting and to allow the hoisting unit to slide on the hoisting moving track.

[0014] Furthermore, several limiting rollers are provided on both sides of the main body of the transport vehicle. The roller shafts of the limiting rollers are fixedly connected to the main body of the transport vehicle, and the limiting rollers are rolledly connected to the side of the protective wall. The limiting rollers are used to limit the left and right displacement of the main body of the transport vehicle when it moves back and forth.

[0015] Furthermore, at least four limiting rollers are provided, with at least two limiting rollers on one side of the main body of the transport vehicle, and the distance between the two farthest limiting rollers on the same side exceeds 65 centimeters.

[0016] Furthermore, the distance between the two furthest bottom rollers exceeds 65 centimeters, and a mobile motor is installed on the main body of the transport vehicle to drive the bottom rollers to rotate.

[0017] The beneficial effects of the track transport device for high-speed railway track slab construction provided by this utility model are as follows: Due to the design of the transport vehicle body, the top of which is the top of the frame, and the hoisting assembly installed on the top of the frame, the tracks can be hoisted using the hoisting assembly on the transport vehicle body during transport. This reduces manual intervention in track transport, thereby minimizing safety hazards and improving efficiency. Furthermore, the hoisting assembly, located on the transport vehicle body, is relatively small in size; the range of track movement during hoisting is also small, making operation simpler.

[0020] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 2 The present invention provides a more detailed description of a track transport device for high-speed railway track slab construction.

[0021] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a track transport device for high-speed railway track slab construction. The device includes a transport vehicle body 100, with several bottom rollers 200 at its bottom. The bottom rollers 200 are used for the transport vehicle body 100 to move on a protective wall 500. The top of the transport vehicle body 100 is a frame top 110, and a lifting assembly is provided on the frame top 110 near its edge.

[0022] In this invention, the lifting assembly includes a first boom 310 and a second boom 320. The first boom 310 is rotatably connected to the top of the vehicle frame 110; the second boom 320 is rotatably connected to the first boom 310; a lifting section 330 is provided at the end of the second boom 320 away from the first boom 310, which is used to lift and lower the lifted track. A lifting moving track 340 is provided on the second boom 320, which is fixedly connected to the second boom 320 and slidably connected to the lifting section 330. The lifting section 330 is used to move the lifted track into or out of the main body 100 of the transport vehicle.

[0023] When in use, the main body 100 of the transport vehicle is placed above the protective wall 500, so that the bottom rollers 200 are in rolling connection with the protective wall 500, that is, the main body 100 of the transport vehicle can move along the protective wall 500.

[0024] After moving the transport vehicle body 100 along the protective wall 500 to the track to be hoisted, rotate the first boom 310 so that it is perpendicular to the transport vehicle body 100. Then rotate the second boom 320 so that it is perpendicular to the first boom 310.

[0025] They are in a vertical relationship. At this point, it is necessary to move the lifting part 330 on the lifting moving track 340 so that the lifting part 330 is directly above the track to be lifted.

[0026] Once the lifting unit 330 is positioned directly above the track to be lifted, the track is lifted using the lifting unit 330. This can be achieved by securing the track with ropes or chains and using a hoist. After the track is lifted to a height higher than the distance between the top 110 and the bottom of the chassis, the lifting unit 330 is moved by the lifting and moving track 340, essentially moving the combination of the lifting unit 330 and the track horizontally towards the top 110 of the chassis. Once the combination of the lifting unit 330 and the track is positioned directly above the transport vehicle body 100, the track is lowered using the lifting unit 330 and placed on the transport vehicle body 100 for transport.

[0027] In actual use, after the track is placed on the main body 100 of the transport vehicle, the main body 100 of the transport vehicle can be fixed together with the track to avoid the safety hazards caused by track displacement during the movement of the main body 100 of the transport vehicle.

[0028] When it is necessary to lift the rails off the main body 100 of the transport vehicle, the first boom 310 and the second boom 320 are deployed, and the rails are lifted by the lifting unit 330. When the lifting unit 330 moves above the position where the rails are to be placed, the lifting unit 330 is controlled to lower the rails, thereby moving the rails to the target position. The whole process is simple to operate, requires less personnel involvement, and is highly efficient.

[0029] The second boom 320, located away from the first boom 310, is rotatably connected to a third boom 350. The third boom 350 is used to support the lifting assembly in contact with the ground. This design enhances the stability of the lifting assembly during the lifting process and further improves the safety of the lifting operation.

[0030] In order to allow the track to be placed in the middle of the top 110 of the frame, the connection point between the lifting assembly and the top 110 of the frame is designed to be at the edge of the top 110 of the frame.

[0031] The top 110 of the frame is provided with several lifting mounting slots 380 for detachable installation of lifting components. To accommodate multiple lifting components and the tracks on both sides of the main body 100 of the lifting and transport vehicle, lifting mounting slots 380 are designed on both sides of the top 110 of the frame. In use, lifting components can be installed in the lifting mounting slot 380 on the side furthest from the track to be lifted. The lifting components can be secured to the top 110 of the frame using bolts or clips.

[0032] Understandably, the top 110 of the chassis is provided with a boom fixing part 360, which is used to store and fix the unused first boom 310, second boom 320 and third boom 350. This design allows the lifting components to be fixed when not in use, preventing damage to the components or other equipment and construction personnel due to lack of fixation.

[0033] The second boom 320 is equipped with a lifting motor 370, which drives the lifting unit 330 to perform lifting operations and to slide the lifting unit 330 on the lifting moving track 340. This design can further reduce the manpower required for construction, thereby further reducing safety hazards and improving work efficiency.

[0034] Several limiting rollers 400 are respectively provided on both sides of the transport vehicle body 100. The roller axles of the limiting rollers 400 are fixedly connected to the transport vehicle body 100, and the limiting rollers 400 are in rolling connection with the side of the protective wall 500. The limiting rollers 400 are used to limit the lateral displacement of the transport vehicle body 100 when it moves back and forth. The limiting rollers 400 can ensure that the transport vehicle body 100 moves on the protective wall 500 or that the transport vehicle body 100 remains above the protective wall 500 during hoisting, thus preventing accidents such as tipping over or the transport vehicle body 100 shifting to a place outside the protective wall 500.

[0035] In actual construction, the track and the main body 100 of the transport vehicle have a certain length. To ensure the limiting rollers 400 can better limit the movement of the main body 100, at least four limiting rollers 400 are installed, with at least two on one side of the main body 100. Since the protective wall 500 has gaps, typically about 65 centimeters long, the distance between the two furthest limiting rollers 400 on the same side must exceed 65 centimeters to ensure proper limiting of the rollers 400. This design ensures that at least four limiting rollers 400 are in contact with the protective wall 500 simultaneously, even if some rollers 400 are trapped in the gaps.

[0036] The distance between the two furthest bottom rollers 200 exceeds 65 centimeters. This design, again aimed at minimizing the impact of gaps in the protective wall, ensures that at least two bottom rollers 200 are in contact with the top of the protective wall 500, thus guaranteeing the normal movement of the transport vehicle body 100. A moving motor is installed on the transport vehicle body 100 to drive the bottom rollers 200. This design eliminates the need for manual pushing by construction workers, further reducing labor costs.

[0037] The motor used in this invention can be a commercially available suitable motor.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
