Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a detachable large-scale floating turnout moving device. Background Art

[0002] Currently, tunnel concrete pouring and material transportation utilize bidirectional rail transport, which transports wet shotcrete, excavation waste, secondary lining steel bars, concrete, and the secondary lining trolleys that occupy the track. This creates a high volume of track traffic, necessitating frequent track changes for passing and shunting. To improve accessibility and ensure the continuity of secondary lining concrete pouring, a sliding floating turnout was added in front of the steel formwork trolleys. However, the floating turnout requires simultaneous traction from two locomotives, which is barely sufficient for movement. The high friction between the floating turnout and the fixed track severely impacts its efficiency. In actual application, when the floating turnout was moved for the first time, two 60T locomotives were used for traction on two lines. Due to the large contact area between the turnout and the track below, the friction increased. The floating turnout is composed of five parts, and there is a 5cm gap between each part. During the movement, the base steel plate of the floating turnout will get stuck in the joint of the fixed track below, further increasing the traction of the floating turnout. At the same time, it also increases the safety risk of moving the floating turnout. The traction speed is slow, reaching 6 hours. Since the two locomotives are operated by two drivers on two lines, it is difficult to achieve synchronous starting. One of the locomotives will first produce active power for traction, resulting in an unbalanced traction direction, further increasing the friction between the floating turnout and the fixed turnout, and increasing the load of the locomotive that produces active power first, which will cause the traction locomotive to be damaged. The repair time of the damaged locomotive is as long as 7 days and economic losses, affecting other operation cycles and construction periods. Therefore, it must be solved to traction the floating turnout. It has become a key issue. Utility Model Content

[0003] The purpose of the utility model is to overcome the problems existing in the prior art and provide a detachable large-scale floating turnout moving device, which reduces the friction between the floating turnout and the fixed turnout, the problem of multiple traction equipment requirements, and reduces the probability of locomotive failure.

[0004] The technical solution of the utility model is as follows: a detachable large-scale floating turnout moving device includes a simple gantry crane and a traveling device, wherein the simple gantry crane is composed of two symmetrically arranged triangular supports, a simple gantry crane beam connected to the triangular supports, a guide chain connected to the simple gantry crane beam, and a traveling wheel connection at the lower part of the triangular supports; the traveling device is composed of a beam, a symmetrically arranged traveling wheel support and a rubber traveling wheel, the two ends of the beam are connected to the traveling wheel support, the lower part of the traveling wheel support is equipped with a rubber traveling wheel, a plurality of riding bolts and screws 2 and ordinary nuts are installed on the beam, and the ordinary nuts are connected to the lifting ears, and a pressure plate is also provided on the beam.

[0005] Further, the cross beam and the walking wheel support are fixedly connected by ordinary bolts.

[0006] The beneficial effects of the utility model are as follows:

[0007] A self-made detachable large floating turnout moving device reduces the friction between the floating turnout and the fixed turnout, solves the problems of the need for a large number of traction devices, reduces the demand for traction locomotives and the probability of locomotive failures. In the transfer moving device, the idle time can be utilized, and the use of the fixed track line by other processes is not affected. During the use process, the installation and disassembly time of the floating turnout moving device is short, the moving speed of the floating turnout is fast, and the influence on the use of the track line is small. On the basis of being safe, fast and practical, the time for moving the floating turnout is greatly shortened. It is applicable to the long-distance rail transportation in medium and small tunnels. When the transportation distance is far, floating turnouts need to be added in the middle. When the floating turnout is far from the construction site, the floating turnout needs to be moved. It is simple to manufacture, reliable in operation and shortens the construction period. Description of the Drawings

[0015] As Figure 1-2As shown in the figure, the detachable large floating turnout moving device of the utility model includes a simple gantry crane and a traveling device. The simple gantry crane is composed of two symmetrically arranged triangular supports 11, a simple gantry crane crossbeam 9 connected to the upper part of the triangular supports 11, a chain hoist 10 connected to the simple gantry crane crossbeam 9, and traveling wheels connected to the lower part of the triangular supports 11; the traveling device is composed of a crossbeam 1, symmetrically arranged traveling wheel supports 6 and rubber traveling wheels 7. The two ends of the crossbeam 1 are connected to the traveling wheel supports 6, and rubber traveling wheels 7 are installed at the lower part of the traveling wheel supports 6. A number of U-bolt screws 2 and ordinary nuts 4 are installed on the crossbeam 1, and a lifting lug 3 is connected to the ordinary nut 4. A pressing plate 5 is also arranged on the crossbeam 1.

[0016] Preferably, the crossbeam 1 and the traveling wheel support 6 are fixedly connected by an ordinary bolt 8.

[0017] Use the chain hoist to lift the floating turnout 3 - 5 cm away from the fixed track, and use the U-bolt screw 2, lifting lug 3, ordinary nut 4, and pressing plate 5 to fix the floating turnout on the traveling device, so as to make the whole floating turnout suspended. The limit blocks on both sides of the bottom track of the floating turnout keep the floating turnout from deviating from the track during movement. Finally, a single locomotive can complete the movement of the floating turnout in a very short time. After all the moving devices are assembled, a single locomotive with a traction force of 60T can be used to carry out traction on one side of the track line. The movement can be completed within 5 minutes, and then the moving device is disassembled. It is not necessary to disassemble and reassemble the floating turnout, and the friction and traction force between the floating turnout and the fixed turnout are reduced, so as to achieve the purpose of moving the floating turnout. Then the floating turnout moving device is removed.

[0018] The detachable floating turnout moving device is convenient for transportation and can be reused many times.

[0019] The assembly and disassembly time of the detachable floating turnout moving device is short, the moving speed is fast, and the influence on the use of the track line is small. During the transfer of the moving device, the idle time can be utilized, and it does not affect the use of the fixed track line by other processes.

[0020] Through one year of use, the detachable floating turnout moving device has not only improved work efficiency, but also reduced the probability of easy damage of the locomotive, and at the same time reduced the safety risk during the movement.
