Description

Technical Field

[0001] This utility model relates to the technical field of track construction equipment, and in particular to a mobile insulated shed travel device for winter construction of ballastless tracks. Background Technology

[0002] In winter, the low temperatures not only make cement difficult to apply during ballastless track construction, but also significantly weaken the mechanical properties of the cement after it sets. Therefore, insulated sheds are often used for insulation during winter ballastless track construction, and heating is then carried out inside these sheds to ensure the cement sets properly in the construction area. To improve the insulation and windproofing effects of these sheds, their structural strength has increased, leading to greater weight and making manual movement increasingly difficult. Summary of the Invention

[0003] The purpose of this utility model is to provide a mobile insulated shed travel device for winter construction using ballastless track, so as to solve the problem of difficulty in moving existing insulated sheds.

[0004] This utility model is achieved through the following technical solution:

[0005] A mobile insulated shed traveling device for winter construction using ballastless track includes a mounting frame and a drive mechanism. The mounting frame is fixed to the side crossbeam of the insulated shed, and the drive mechanism is fixedly mounted on the mounting frame. The drive mechanism is used to drive the insulated shed to move on the track. Two sets of the drive mechanism are symmetrically arranged on the mounting frame. Each set of the drive mechanism includes two drive wheels, and the drive wheels on the two sets of drive mechanisms are respectively placed on both sides of the track.

[0006] In one possible design, the drive wheel is fixedly provided with a threaded protrusion. When the drive wheel rotates to drive the insulation shed to move, the contact engagement between the threaded protrusion and the track can provide downward pressure on the entire traveling device on the mounting frame.

[0007] In one possible design, a U-shaped frame is fixed to the mounting bracket, and bolt holes are provided on the U-shaped frame.

[0008] In one possible design, the drive mechanism further includes a geared drive motor, a transmission mechanism, and a drive wheel frame mechanism. The body of the geared drive motor is fixed on the mounting frame, and the drive wheel frame mechanism includes a fixed frame and a swing wheel frame.

[0009] In one possible design, the fixed frame is fixed to the mounting frame, and two symmetrical swing wheel frames are provided at opposite ends of the fixed frame. One end of the swing wheel frame is hinged to the fixed frame, and the other end of the fixed frame is rotatably provided with the drive wheel. Each swing wheel frame is also connected to the fixed frame by a tension spring.

[0010] In one possible design, the transmission mechanism includes a first transmission sprocket set and a second transmission sprocket set. The first transmission sprocket set includes a driving sprocket and a first transmission chain. The driving sprocket is fixed on the motor shaft of the reduction drive motor and meshes with the first transmission chain. The second transmission sprocket set includes a second transmission chain and a driven sprocket. The second transmission chain meshes with the driven sprocket. The first transmission sprocket set and the second transmission sprocket set are connected by an intermediate sprocket. The intermediate sprocket meshes with the first transmission chain and also with the second transmission chain.

[0011] In one possible design, the intermediate sprocket is rotatably mounted on a fixed shaft, which is fixed to a fixed frame. The swing wheel frame is hinged to the fixed frame via the fixed shaft, and the fixed frame is fixed to the mounting frame by bolts.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0013] This utility model uses a mounting frame and a drive mechanism to drive the insulation shed, making the movement of the insulation shed easier and more convenient. The overall movement device is simple and easy to disassemble, facilitating the assembly and disassembly of the insulation shed. At the same time, through the cooperation of the swing wheel frame and the drive wheel, the drive wheels on both sides of the track can automatically clamp onto the track, ensuring that the walking mechanism provides sufficient thrust to the insulation shed.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Examples, such as Figures 1 to 8 As shown, a mobile insulated shed traveling device for winter construction using ballastless track includes a mounting frame 1 and a drive mechanism. The mounting frame 1 is fixed to the side crossbeam of the insulated shed, and the drive mechanism is fixedly installed on the mounting frame 1. Two sets of the drive mechanism are symmetrically arranged on the mounting frame 1. Each set of the drive mechanism includes two drive wheels 3. The drive wheels 3 on the two sets of drive mechanisms are respectively placed on both sides of the track. The track is clamped by the drive wheels 3 on both sides of the track, and the insulated shed is moved forward by controlling the drive wheels 3 to roll on the track.

[0026] In this embodiment, a U-shaped frame 101 is fixed on the mounting frame 1. The U-shaped frame 101 has bolt holes 102. The U-shaped frame 101 cooperates with the side beam on the insulation shed, and the traveling device is quickly installed on the insulation shed by bolts through the bolt holes 102. The whole is easy to assemble and disassemble, and can form a firm and tight fit after connection.

[0027] In this embodiment, the drive mechanism further includes a reduction drive motor 2, a transmission mechanism, and a drive wheel 3 frame mechanism. The body of the reduction drive motor 2 is fixed on the mounting frame 1. The drive wheel 3 frame mechanism includes a fixed frame 5 and a swing wheel frame 4. The fixed frame 5 is fixed to the mounting frame 1. Two symmetrical swing wheel frames 4 are provided at opposite ends of the fixed frame 5. One end of the swing wheel frame 4 is hinged to the fixed frame 5, and the drive wheel 3 is rotatably provided at the other end of the fixed frame 5. Each swing wheel frame 4 is also connected to the fixed frame 5 by a tension spring. The tension spring makes the drive wheel 3 fit tightly against the track through the swing wheel frame 4.

[0028] Further, the transmission mechanism includes a first transmission sprocket set 7 and a second transmission sprocket set 8. The first transmission sprocket set 7 includes a driving sprocket 701 and a first transmission chain 702. The driving sprocket 701 is fixed on the motor shaft of the reduction drive motor 2, and the driving sprocket 701 meshes with the first transmission chain 702, thus driving the first transmission chain 702. The second transmission sprocket set 8 includes a second transmission chain 801 and a driven sprocket 802. The second transmission chain 801 meshes with the driven sprocket 802. The first transmission sprocket group 7 and the second transmission sprocket group 8 are connected by an intermediate sprocket 9. The intermediate sprocket 9 meshes with the first transmission chain 702 and also meshes with the second transmission chain 801. The rotation of the driving sprocket 701 is transmitted to the intermediate sprocket 9 through the first transmission chain 702. The intermediate sprocket 9 then transmits the rotation to the driven sprocket 802 through the second transmission chain 801. The driven sprocket 802 is fixed to the drive wheel 3. Thus, the drive wheel 3 can be driven by the reduction drive motor 2.

[0029] In this embodiment, the intermediate sprocket 9 is rotatably mounted on the fixed shaft 10, the fixed shaft 10 is fixed to the fixed frame 5, the swing wheel frame 4 is hinged to the fixed frame 5 through the fixed shaft 10, and the fixed frame 5 is fixed to the mounting frame 1 by bolts, which facilitates disassembly and installation during subsequent maintenance.

[0030] It should be noted that this embodiment only discloses two drive wheels 3 on the side of the track. In one usage, the side beam of the insulation shed is provided with rollers, and the rollers roll at the top of the track, so that the traveling device only needs to provide the force for the rollers to move on the track. In another usage, if there are no rollers on the beam of the insulation shed, rollers can also be installed below the mounting frame 1 to support the insulation shed to move on the track.

[0031] Advantageously, the drive wheel 3 is fixedly provided with a threaded protrusion 301. When the drive wheel 3 rotates to drive the insulation shed to move, the contact and cooperation between the threaded protrusion 301 and the track can provide the entire traveling device with downward pressure on the mounting frame 1, so that the entire traveling device can firmly press the side of the insulation shed down onto the track when it moves, so as to ensure that the insulation shed is not blown over by a sudden strong wind when it moves.

[0032] It should be noted that the reference Figure 8 Two drive wheels 3 are provided on both sides of the track. The threaded protrusions 301 on the two drive wheels 3 on each side rotate in opposite directions. When the traveling device moves back and forth, different drive wheels 3 drive the traveling device, thereby ensuring that the threaded protrusions 301 on the drive wheels 3 always play the role of driving the insulation shed to press down.

[0033] Working principle:

[0034] First, fix the entire device to the side beam of the insulation shed. After fixing, the rotation of the reduction drive motor 2 can be controlled to drive the insulation shed to move. Taking the second transmission sprocket group 8 in the figure as an example, when the moving device moves to the right along the track, it is mainly driven by the right drive wheel 3. The right drive wheel 3 gives the swing wheel frame 4 a left-up thrust, and the swing wheel frame 4 gives the drive wheel 3 a right-down pressure, so that the drive wheel 3 presses tightly against the track, while the left drive wheel 3 is not subjected to downward pressure. When the direction of movement is reversed, it will switch to the left drive wheel 3 to push the moving device to move. The threaded protrusions 301 on the left and right drive wheels 3 rotate in opposite directions, so that no matter which direction the movement is, the threaded protrusions 301 on the drive wheel 3 can give the drive wheel 3 a downward pressure, making the insulation shed more stable when moving and effectively preventing it from being blown over by the wind.

[0035] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific 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.
