[0020] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] As Figures 1 to 5 shown, an embodiment of the present utility model provides a retractable tarpaulin device for a freight car carriage, which includes a car body 1, on which a guardrail 2 is provided, and a tarpaulin body 602 is laid on the guardrail 2; a retracting and releasing assembly, including a storage member provided on one side of the car body 1 and a driving member provided on the other side of the car body 1, the storage member and the driving member are respectively connected to both ends of the tarpaulin body 602, the storage member is used for storing the tarpaulin body 602, and the driving member is used for adjusting the position of the tarpaulin body 602; a limiting device, including a ratchet wheel 404 provided on the driving member and a clamping member provided on the car body 1, and the clamping member is used for restricting the rotation of the driving member.

[0022] The detailed working process of this embodiment is as follows: The car body 1 is installed on the vehicle body, and the tarpaulin is used for shading and rain protection. Through the arrangement of the storage member and the driving member, the tarpaulin is stored in the storage member and laid through the driving member. When it is necessary to lay the tarpaulin on the roof, the driving member is operated to pull out the tarpaulin in the storage member and lay it along the guardrail 2, so as to achieve the effect of shading and rain protection. At the same time, it is restricted by the limiting device to prevent the tarpaulin from being blown over during the driving of the vehicle. When it needs to be retracted, the clamping member is disengaged from the ratchet wheel 404, and then the laid tarpaulin is retracted through the storage member.

[0023] As Figure 2 shown, the guardrail 2 includes an arched frame 201 and arch gate frames 202 fixedly connected to both ends of the arched frame 201. Among them, guide rails 203 are provided on the side walls of the two arch gate frames 202.

[0024] As Figure 2 And Figure 5 shown, the storage member includes a storage bin 3 provided on one side of the car body 1 and a second rotating shaft 301 rotatably provided in the storage bin 3. A channel 302 is provided on the storage bin 3, and one end of the tarpaulin body 602 passes through the channel 302 and is connected to the second rotating shaft 301.

[0025] The detailed working process of this embodiment is as follows: The storage bin 3 is used for storing the tarpaulin. One end of the tarpaulin body 602 is connected to the second rotating shaft 301. When the second rotating shaft 301 is rotated, the tarpaulin body 602 is wound around the second rotating shaft 301 to complete the storage.

[0026] As Figure 1 And Figure 3 shown, the driving member includes a guide shaft 6 connected to the other end of the tarpaulin body 602 and a first rotating shaft 4 rotatably provided on the car body 1. Winding rollers 401 are fixedly provided at both ends of the first rotating shaft 4, and steel cables 403 are provided on both winding rollers 401. One ends of the two steel cables 403 are respectively provided at both ends of the guide shaft 6.

[0027] The detailed working process of this embodiment is as follows: The guiding shaft 6 is used to guide one end of the tarpaulin. When the tarpaulin needs to be laid, the guiding shaft 6 can be directly pulled. The two wire winding rollers 401 are used to store the steel cable 403. One end of the steel cable 403 is fixedly connected to the guiding shaft 6. By rotating the first rotating shaft 4 to drive the wire winding roller 401 to rotate, the steel cable 403 is recovered. When the steel cable 403 is recovered, the tarpaulin will be pulled out from the storage bin 3, and then the laying can be carried out.

[0028] As Figure 3 shown, rollers 601 are arranged at both ends of the guiding shaft 6, and the two rollers 601 are respectively located in the corresponding guide rails 203.

[0029] The detailed working process of this embodiment is as follows: The function of the roller 601 is to convert sliding friction into rolling friction to reduce the frictional force. The roller 601 is located in the guide rail 203 and can move along the guide rail 203. At the same time, the steel cable 403 connected to the guiding shaft 6 can stretch and contract in the guide rail 203. Under normal conditions, the tarpaulin body 602 is wound around the second rotating shaft 301 and placed in the storage bin 3. When the tarpaulin needs to be laid, the first rotating shaft 4 is rotated to drive the wire winding roller 401 to rotate, and the steel cable 403 is recovered to pull the tarpaulin out of the storage bin 3. The roller 601 moves along the guide rail 203 until the entire tarpaulin is pulled out and covered on the guardrail 2 on the vehicle roof.

[0030] As Figure 4 shown, the clamping member includes a limit seat 5 arranged on one side of the cargo bed 1. A limit bin 504 and a slideway 502 are opened on the limit seat 5. The limit bin 504 is communicated with the slideway 502. A clamping tooth 503 is slidably arranged on the limit bin 504. A return spring 505 is arranged at the bottom of the clamping tooth 503. The clamping tooth 503 is clamped on the ratchet wheel 404 under the elastic force of the return spring 505. Among them, a column 506 is fixedly arranged on the clamping tooth 503, and the column 506 is located in the slideway 502.

[0031] The detailed working process of this embodiment is as follows: The ratchet wheel 404 is limited by the clamping tooth 503 to limit the first rotating shaft 4, providing a force for the steel cable 403. When the tarpaulin is stressed, the steel cable 403 pulls it to prevent the tarpaulin from being recovered. The clamping tooth 503 is always clamped on the ratchet wheel 404 under the elastic force of the return spring 505, so that the ratchet wheel 404 can only rotate in one direction. When reverse rotation is required, by controlling the column 506, the clamping tooth 503 can be driven to disengage from the ratchet wheel 404.

[0032] As Figure 4 shown, a limit hole 501 is arranged at the lower end of the slideway 502, and a sleeve 507 is sleeved on the column 506.

[0033] The detailed working process of this embodiment is as follows: under the setting of the limiting hole 501 and the sleeve 507, the latching tooth 503 can be controlled to be disengaged from the ratchet 404 for a long time, which is convenient for operation; specifically, by moving the column 506 downward and moving it to the limiting hole 501 of the slide 502, the sleeve 507 is pushed down so that the sleeve 507 is stuck in the limiting hole 501, and the latching tooth 503 is restricted. At this time, the reset spring 505 is in a state of storing force. When the latching tooth 503 needs to be stuck in the ratchet 404, the sleeve 507 can be directly lifted.

[0034] like Figure 3 As shown, a hexagonal prism 402 is provided at one end of the first rotating shaft 4 .

[0035] like Figure 1 As shown, a hexagonal prism 402 is provided at one end of the second rotating shaft 301 .

[0036] The detailed working process of this embodiment is as follows: the head of the hexagonal prism 402 can be conveniently tightened or loosened using a wrench or other tools, thereby improving working efficiency.

[0037] The implementation principle of the embodiment of the present application is as follows: the tarpaulin body 602 is wound around the second rotating shaft 301 and placed in the storage bin 3. When the tarpaulin needs to be laid, the first rotating shaft 4 is rotated to drive the wire roller 401 to rotate, and the steel cable 403 pulls the tarpaulin out of the storage bin 3 during the recovery process. The roller 601 moves along the guide rail 203 until the tarpaulin is completely pulled out and covers the guardrail 2 on the roof. At this time, the tarpaulin is tightened and the laying is completed. When the tarpaulin needs to be stored, the column 506 is moved downward to the limiting hole 501 of the slide 502, and the sleeve 507 is pushed down so that the sleeve 507 is stuck in the limiting hole 501, and the locking tooth 503 is restricted. Then, the second rotating shaft 301 is rotated, and the tarpaulin body 602 is wound around the second rotating shaft 301 to complete the storage.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
