[0023] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0024] As Figures 1 to 4 shown, an installation device for a tarpaulin of a freight car carriage proposed in the embodiment of the present utility model is installed on the cargo box 1 and used for installing the tarpaulin 2, and includes:

[0025] A number of frameworks 3 are installed on the cargo box 1, and the tarpaulin 2 is laid on the number of frameworks 3;

[0026] Two mounting plates 4 are provided on both sides of the cargo box 1. Both of the two mounting plates 4 are provided with sliding grooves. Both ends of the framework 3 are provided with sliders 301, and the sliders 301 are slidably arranged in the sliding grooves of the corresponding mounting plates 4; and

[0027] A pull rope 8 is arranged in the sliding groove and extends out of both ends of the mounting plate 4, and is fixedly connected to the slider 301 at the end of the sliding groove. The mounting plate 4 is provided with a vertical plate 401. A storage wheel 6 is rotatably arranged on the vertical plate 401. Both ends of the pull rope 8 are wound on the storage wheel 6, so that when the storage wheel 6 rotates, the frameworks 3 approach or separate from each other, and the tarpaulin 2 is folded or unfolded.

[0028] In the embodiment of the present utility model, taking Figure 1 as an example, the two mounting plates 4 are respectively installed on both sides of the cargo box 1, and then the sliders 301 at both ends of the framework 3 are respectively clamped into the sliding grooves of the two mounting plates 4. Among them, the left side position of the cargo box 1 is the unloading position, so the slider 301 at the other end is fixedly installed in the sliding groove as the storage position of the tarpaulin 2, and the remaining frameworks 3 are all slidably arranged in the sliding grooves of the mounting plate 4 through the sliders 301. The pull rope 8 is fixedly connected to the slider 301 close to the unloading position, and the pull rope 8 movably penetrates through all the remaining sliders 301. When the pull rope 8 is pulled to the left, the pull rope 8 drives the fixedly connected slider 301 to slide, so that the framework 3 provided by it moves towards the left side position of the cargo box 1, and under the pulling of the tarpaulin 2, the frameworks 3 are unfolded, so as to realize the unfolding of the tarpaulin 2; when the pull rope 8 is pulled to the right, the pull rope 8 drives the fixedly connected slider 301 to slide, so that the framework 3 provided by it moves towards the right side position of the cargo box 1, so that the frameworks 3 approach each other. Since the tarpaulin 2 is soft in texture, the tarpaulin 2 can shrink by itself when the frameworks 3 approach each other, so that the tarpaulin 2 can be stored on one side under the movement of the frameworks 3 for convenient subsequent use again.

[0029] Specifically, as Figure 3 shown, a connecting rod 601 is provided at the bottom of the cargo box 1, and the connecting rod 601 is connected between the two storage wheels 6; under the action of the connecting rod 601, when the connecting rod 601 is rotated, the storage wheels 6 on the two mounting plates 4 can be adjusted synchronously, so as to move both sides of the framework 3 synchronously, which is more convenient.

[0030] Based on the above scheme, as Figure 3 shown, a worm gear 7 is rotatably arranged on the vertical plate 401. The rotating shaft of the worm gear 7 passes through the vertical plate 401 and is connected to the storage wheel 6. The vertical plate 401 is also correspondingly provided with two mounting blocks 402. A worm 5 is rotatably arranged between the two mounting blocks 402, and the worm 5 meshes with the worm gear 7.

[0031] When adjusting the storage wheel 6, the worm 5 can be rotated, so that the worm 5 drives the worm wheel 7 to rotate. While the worm wheel 7 is rotating, it can drive the connecting rod 601 and the two storage wheels 6 to rotate. When the worm 5 stops rotating, the worm wheel 7 will not rotate under the locking of the worm 5. Thus, when the tarpaulin 2 is unfolded or stored in a designated position, the tarpaulin 2 can be ensured to stay in the current position and will not move due to external factors. Moreover, an adjusting nut 701 is provided at the end of the worm 5, which facilitates the operator to adjust the worm 5 with tools and is more labor-saving.

[0032] Specifically, as Figure 4 shown, two limiting grooves 602 are formed in the storage wheel 6, and both ends of the pull rope 8 are respectively wound in the two limiting grooves 602; during the rotation of the storage wheel 6, both ends of the pull rope 8 always perform retracting and releasing movements. In order to avoid interference between both ends of the pull rope 8, both ends of the pull rope 8 can be separated by the two limiting grooves 602, which can avoid interference and ensure normal adjustability.

[0033] Specifically, as Figure 4 shown, the slider 301 is provided with a pulley group 302, and the pulley group 302 is in rolling connection with the sliding groove; under the action of the pulley group 302, the rolling contact with the sliding groove replaces the traditional sliding contact, greatly reducing the friction force, making the sliding of the framework 3 smoother, reducing the movement resistance, and having less wear relative to the wear generated by sliding friction. The design of the pulley group 302 can effectively extend the service life of the slider 301 and the sliding groove.

[0034] Specifically, as Figure 4 shown, guide wheels 404 are rotatably provided at both ends of the mounting plate 4, and the pull rope 8 is arranged on the guide wheels 404; under the action of the guide wheels 404, the direct friction between the pull rope 8 and the mounting plate 4 can be reduced, thereby reducing the wear of the pull rope 8 and extending the service life of the pull rope 8, and it can ensure that the pull rope 8 runs along the correct path and guarantee the smooth movement of the pull rope 8.

[0035] Specifically, as Figure 1 shown, the mounting plate 4 is provided with a plurality of connecting seats 403, and the plurality of connecting seats 403 are all connected to the cargo box 1; the connecting seats 403 are in an L-shaped structure, and through holes are formed in both working surfaces. Bolts can be inserted into the two through holes, and the mounting plate 4 can be quickly assembled to the side of the cargo box 1. The detachable design also facilitates subsequent maintenance.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
