[0002] Bridge deck construction is a crucial part of bridge engineering, mainly referring to the construction of the structural system in the bridge superstructure that directly bears vehicle and pedestrian loads and the effects of the natural environment.

[0003] Some bridge deck construction projects use rail transport for materials. Material transport is an important part of bridge deck construction, providing follow-up support for the project: transportation of machinery and equipment, turnover and allocation of materials, etc. Timely preparation and availability of materials and equipment can ensure smooth production and construction, accelerate the construction progress, and improve construction efficiency.

[0004] For transporting materials on bridge deck tracks, tracks are usually pre-set, and transfer trolleys are set on the tracks. The transfer trolleys are moved by means of integrated drive mechanisms and track-mounted traction ropes. However, the rollers of the trolleys are usually fixed. When the track is not straight or turns, the wear between the transfer trolley and the track can easily cause it to derail. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a bridge deck construction track transfer device, comprising: a carriage 1, a bearing shaft 5, and track steel wheels 6;

[0027] The bearing shaft 5 is located on the left and right sides of the lower surface of the carriage 1. Both ends of the bearing shaft 5 are rotatably connected to the rail steel wheel 6 through bearings. The bearing shaft 5 on the left side is a steering shaft, and a steering support mechanism is provided on the upper part of the steering shaft. A support rod 7 is connected to the bearing shaft 5 on the right side. The steering support mechanism and the support rod 7 are connected to the lower surface of the carriage 1.

[0028] Analysis of the above content: In use, the carriage 1 is connected to the traction rope on the track (the traction rope here is similar to the traction rope of the railcar in the coal mine. The traction rope moves along the track. After the traction rope is connected to the carriage 1, the traction rope can drive the carriage 1 to move).

[0029] After towing the trolley to the location where the materials are needed, simply unload the materials from the trolley.

[0030] The steering shaft can rotate relative to the carriage 1 through the steering support mechanism, so that the trolley can move smoothly on the track.

[0031] Example 2:

[0032] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the carriage 1 is hollow and open at the top and left side. The left side opening of the carriage 1 is rotatably connected to the panel 2 by a pin. The upper part of the panel 2 is connected to the upper opening of the carriage 1 by a connecting pin.

[0033] Analysis of the above content: When the panel 2 is closed, it acts as a barrier to prevent the materials inside the carriage 1 from falling out. When it is necessary to unload the materials from the carriage 1, the panel 2 can be opened. The lower side of the panel 2 is rotatably connected to the lower part of the left opening of the carriage 1 through a pin. A connecting pin is inserted into the upper part of the left opening of the carriage 1. The panel 2 has corresponding pin holes for insertion and mating. If the operation is bumpy, the connecting pin can be replaced with a bolt, and the pin hole can be adjusted to a screw hole.

[0034] Example 3:

[0035] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 2: the left side wall of the panel 2 is connected to a traction hook 3.

[0036] Analysis of the above content: A buckle can be set on the traction rope, and the traction hook 3 can be hooked to the buckle for easy connection and disassembly.

[0037] Example 4:

[0038] Please see Figure 1-4 Based on Embodiment 3, this utility model provides a technical solution: the lower left side wall of the panel 2 is provided with a slot 4 for positioning the traction hook 3.

[0039] Analysis of the above: The slot 4 restricts and positions the traction hook 3. When the trolley moves to the left, the traction rope connected to the traction hook 3 moves to the left and pulls the carriage 1. When the trolley moves to the right, the traction rope pulls the traction hook 3 and the carriage 1 to the right. At this time, the traction hook 3 is pulled into the slot 4 by the traction rope, making it less likely for the traction hook 3 to slip sideways.

[0040] Example 5:

[0041] Please see Figure 1-4 Based on Embodiment 2, this utility model provides a technical solution: the bearing shaft 5 is convex upward.

[0042] Analysis of the above: The bearing shaft 5 is convex upwards and will not come into contact with the traction rope on the lower side, thus avoiding friction damage to the traction rope.

[0043] Example 6:

[0044] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the steering support mechanism includes a support column 8, the bottom end of the support column 8 is fixedly connected to the outer wall of the left bearing shaft 5, a bearing seat assembly 9 is rotatably connected to the upper side of the outer wall of the support column 8, and the upper end of the bearing seat assembly 9 is connected to the left side of the lower surface of the carriage 1.

[0045] Analysis of the above content: The bearing housing assembly 9 includes an external bearing housing and a bearing installed inside the bearing housing. The outer ring of the bearing is fixedly embedded and connected to the inner wall of the bearing housing, and the inner ring of the bearing is fixedly connected to the upper end of the support column 8. In this way, the support column 8 can rotate relative to the bearing housing through the bearing and can rotate relative to the carriage 1.

[0046] Example 7:

[0047] Please see Figure 1-4 This utility model provides a technical solution based on embodiment six: the outer wall of the bearing seat assembly 9 is provided with a fork 10, and a limiting rod 11 is connected to the outer wall of the support column 8, with the upper end of the limiting rod 11 inserted into the fork 10.

[0048] Analysis of the above content: When the support column 8 rotates relative to the carriage 1 through the bearing, the support column 8 simultaneously drives the limiting rod 11 to rotate within the fork 10. Due to the restriction of the fork 10, the rotation range of the support column 8 and the limiting rod 11 will not be too large (the internal opening size of the fork 10 is set according to the specific track turning radius, so that the maximum rotation range of the support column 8 conforms to the track turning radius).

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description.
