Description

Technical Field

[0001] This utility model relates to the field of track laying equipment technology, specifically to a hydraulically driven tire-type track laying machine. Background Technology

[0002] In railway tunnel construction, track laying machines are commonly used equipment. They are mainly used to transport track panels or track slabs from track flatcars to the construction work surface inside the tunnel to complete the laying of track panels or track slabs. However, existing track laying machines rely on temporary tracks for movement and cannot flexibly move on unformed roadbeds, which limits the construction range, increases costs, and makes it difficult to align the center of the track panel with the center line of the designed road. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0010] The beneficial effects of this utility model are as follows: (1) By setting up a motor to drive the tires and controlling the first traveling mechanism to turn by the steering jack, the track laying machine can move flexibly and turn on curves in complex sites such as unformed roadbeds and tunnel surfaces, thereby improving the efficiency of site transfer and construction.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings. The following description is based on the accompanying drawings. Figure 1 The direction in the middle is the reference.

[0017] like Figure 1-4 As shown, this utility model provides a hydraulically driven tire-type 65 track laying machine, including two horizontally spaced lower support beams 1. Each support beam is equipped with a hydraulic station 2, a battery 3, a control cabinet 4, and a driving system 5. A first traveling mechanism 6 is provided at one end of the bottom surface of each of the two lower support beams 1, and a second traveling mechanism 7 is provided at the other end of the bottom surface of each of the two lower support beams 1. Two spaced-apart masts 8 are spanned between the top surfaces of the two lower support beams 1. A connecting beam 9 is fixedly connected between the upper parts of the two masts 8. Each mast 8 includes a crossbeam 81 and two support legs 82. A slider 10 is slidably connected to each of the two crossbeams 81. A transverse jack 11 is hinged between one end of the slider 10 and one end of the crossbeam 81. The bottom surfaces of the two sliders 10 are connected... A main beam 12 is fixedly connected, and a chain hoist 13 for lifting the rail panel is mounted on the main beam 12; the first traveling mechanism 6 includes a first tire bracket 61, the top of the first tire bracket 61 is rotatably connected to the lower support beam 1 through a bearing 62, a steering jack 63 is hinged between the first tire bracket 61 and the bottom surface of the lower support beam 1, a first rotating shaft 64 is rotatably connected to the lower part of the first tire bracket 61, a motor 66 is mounted on the first tire bracket 61, the output shaft of the motor 66 is drively connected to the first rotating shaft 64, and a tire 65 is mounted on the first rotating shaft 64; the second traveling mechanism 7 includes a second tire bracket 71, a second rotating shaft 72 is rotatably connected to the lower part of the second tire bracket 71, and a tire 65 is mounted on the second rotating shaft 72.

[0018] Specifically, during use, the control cabinet 4 starts the motor 66, which drives the tire 65 to rotate, thereby enabling the track laying machine to move on the unformed roadbed and tunnel surface. At the same time, the steering jack 63 extends and retracts, pushing the first tire bracket 61 to rotate around the bearing 62. The first tire bracket 61 can drive the tire 65 to deflect, thereby enabling turning on curves, facilitating flexible relocation on the unformed roadbed and improving construction efficiency. In addition, the lateral movement jack can drive the slider 10 to move laterally, and the slider 10 drives the main beam 12 and the chain hoist 13 to move laterally, thereby driving the track panel to move laterally for fine adjustment, making it easier to align the center line of the track panel with the center line of the road.

[0019] In some embodiments, the top end of the second tire bracket 71 is rotatably connected to the lower support beam 1 via a bearing 62, and a steering jack 63 is hinged between the second tire bracket 71 and the bottom surface of the lower support beam 1. Specifically, when the first traveling mechanism 6 turns, the steering jack 63 pushes the second tire bracket 71 to rotate synchronously, and the second tire bracket 71 drives the tire 65 to deflect. At this time, the first traveling mechanism 6 and the second traveling mechanism 7 turn synchronously, thereby enabling flexible turning on small-radius curves.

[0020] In some embodiments, the top end of the second tire bracket 71 is fixedly connected to the lower support beam 1. Specifically, when the first traveling mechanism 6 travels or turns, the tire 65 on the second tire bracket 71 moves as a driven wheel.

[0021] In some embodiments, the support leg 82 includes a guide column 821 fixedly connected to the lower support beam 1, a guide cylinder 822 slidably connected to the guide column 821, the top end of the guide cylinder 822 being fixedly connected to the crossbeam 81, and a lifting jack 83 hinged between the guide cylinder 822 and the lower support beam 1. Specifically, in use, the lifting jack 83 is controlled to extend and retract, and the lifting jack 83 pushes the guide cylinder 822 to slide along the guide column 821, thereby enabling the overall lifting and lowering of the gantry 8 to facilitate adjustment of the overall height of the gantry 8 to the construction height.

[0022] In some embodiments, the guide column 821 has a plurality of first through holes 823 evenly distributed vertically, and the guide cylinder 822 has a second through hole 824. A pin 825 is inserted into the second through hole 824 and one of the first through holes 823. Specifically, after the height of the gantry 8 is adjusted to the correct position, the second through hole 824 and one of the first guide holes are aligned and the pin 825 is inserted to form a mechanical rigid support. When the lifting jack 83 fails, the height of the gantry 8 can still be maintained, thereby improving the stability of the gantry 8.

[0023] The above embodiments can be combined with each other.

[0024] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
