Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of transportation machinery, and in particular to a truck tarpaulin system and a truck compartment. Background Art

[0002] With the continuous development of animal husbandry, its scale is getting bigger and bigger. At this stage, as the country has increased its efforts to govern the environment, the animal husbandry industry implements centralized breeding and management, so breeding and fattening need to be more professional. The next problem is the need for dedicated logistics and transportation tools to support it. For example; for traditional livestock transport vehicles, since the transportation environment is greatly affected by the external environment, closed compartments are generally used to transport livestock. On the one hand, the internal air circulation is not smooth, which can easily lead to livestock hypoxia; on the other hand, the closed environment will cause the compartment temperature to rise sharply, especially when transporting livestock in summer. If there is a traffic jam, the temperature in the compartment may be as high as 40-50℃, which is very likely to cause the death of livestock and cause significant losses to the driver.

[0003] This shows that the existing technology needs to be further improved and enhanced. Utility Model Content

[0052] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the accompanying drawings show exemplary embodiments of the present invention, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0053] Reference Figures 1-4 As shown, an embodiment of the present invention provides a truck tarpaulin system, which is applied to a truck compartment, including a tarpaulin rack 100 with an open top and a tarpaulin cover 200 for opening or closing the opening, as well as a water supply channel (not marked in the figure) and a temperature control device 300. The tarpaulin rack 100 has a first installation area (not marked in the figure), and the tarpaulin cover 200 has a second installation area (not marked in the figure). The water supply channel is provided on the tarpaulin rack 100 and / or the tarpaulin cover 200 for supplying water to the interior of the truck compartment; the temperature control device 300 is provided in the first installation area and / or the second installation area for regulating the temperature inside the truck compartment.

[0054] It should be noted that truck carriages used for transporting livestock, such as pig carriages and cattle carriages, generally come in a variety of sizes, with common sizes including double-layer 5.5-meter, double-layer 9.6-meter, triple-layer 9.6-meter, and triple-layer 13-meter. When a truck tarpaulin system is installed on the outside of carriages of different sizes, the specific sizes of the tarpaulin cover 200 and tarpaulin frame 100 in the truck tarpaulin system should also be compatible with the carriages of different sizes. This application does not limit the specific sizes of the truck tarpaulin system.

[0055] It should also be noted that the first mounting area refers to the side, front, and rear areas of the tarpaulin frame 100, while the second mounting area refers to the planar area of ​​the tarpaulin cover 200. Specifically, the tarpaulin frame 100 includes a pair of horizontal bars 110, respectively disposed at the front and rear ends of the truck compartment, and a plurality of upright posts 120 connected to the horizontal bars 110. The horizontal bars 110 and the upright posts 120 enclose a first mounting area, i.e., the front and rear areas of the tarpaulin frame 100, or the area between two adjacent upright posts 120 encloses a first mounting area, i.e., the side areas of the tarpaulin frame 100. The number of these side areas can be one or two. Furthermore, the tarpaulin cover 200 includes a pair of horizontal beams 210, corresponding to the pair of horizontal bars 110, and a pair of side beams 220, respectively connected to the horizontal beams 210. The horizontal beams 210 and the side beams 220 enclose a second mounting area, i.e., the planar area of ​​the tarpaulin cover 200.

[0056] Furthermore, it should be noted that the water supply channel in the present application can be provided on either the tarpaulin frame 100 or the tarpaulin cover 200, or the water supply channel can be provided on both the tarpaulin frame 100 and the tarpaulin cover 200. For example, the water supply channel can be a hollow water pipe fixedly connected to the outer wall of the horizontal bar 110, the upright stakes 120, the crossbeam 210, or the side beam 220; or the horizontal bar 110, the upright stakes 120, the crossbeam 210, and the side beam 220 are all hollow structures, and the water supply channel is embedded in the hollow horizontal bar 110, the upright stakes 120, the crossbeam 210, or the side beam 220; or the water supply channel is formed by the hollow inner wall of the horizontal bar 110, the upright stakes 120, the crossbeam 210, and the side beam 220, i.e., the water supply channel is formed inside the hollow horizontal bar 110, the upright stakes 120, the crossbeam 210, and the side beam 220. It can be found that the structure or formation method of the water transfer channel can be various, and this application does not limit this.

[0057] The primary function of the temperature control device 300 is to regulate the temperature within the vehicle compartment. Therefore, the temperature control device 300 can be of various types. For example, it can be a fan or air conditioner for lowering the temperature within the vehicle compartment, or a heater or heating device for raising the temperature within the vehicle compartment. This application does not limit the type of temperature control device 300. Furthermore, the truck tarpaulin system of this application may also include lighting devices and alarm devices disposed on the tarpaulin frame 100 and / or the tarpaulin cover 200.

[0058] The truck tarpaulin system provided herein utilizes water channels to supply water from the sides and / or top of the vehicle compartment. This not only provides sufficient moisture for livestock within the compartment but also reduces the compartment temperature to a certain extent, thereby improving the living environment for the livestock. Furthermore, the temperature control device 300 is provided to allow the truck tarpaulin system to supply air from the sides or top of the compartment to regulate the temperature within the compartment. Because the temperature control device 300 not only reduces but also increases the temperature within the compartment, the truck tarpaulin system can ensure the safety of livestock in a variety of complex external environments, improve the livestock environment, and significantly reduce livestock mortality during transportation.

[0059] In some embodiments, reference Figure 1As shown, a pair of horizontal bars and multiple piles are each provided with a water inlet (shown in the figure), and a pair of horizontal beams and a pair of side beams are each provided with a water injection port (not shown in the figure). In addition, the water supply channel includes a first water supply pipe (not shown in the figure), a second water supply pipe (not shown in the figure), and a water supply pipe 230. The first water supply pipe is disposed inside the pair of horizontal bars and multiple piles and is connected to the water inlet; the second water supply pipe is disposed inside the pair of horizontal beams and a pair of side beams and is connected to the water injection port; the water supply pipe 230 is connected to the first water supply pipe and has a water supply port facing the interior of the vehicle compartment (not shown in the figure).

[0060] It should be noted that the water supply channels provided on the tarpaulin frame 100 and the tarpaulin cover 200 reduce the temperature inside the vehicle compartment by injecting water into the compartment. To enhance the cooling effect, nozzles may be provided at the open ends of the water supply channels, i.e., the water inlet, water injection port, and water supply port, to atomize the water and thereby conserve water to a certain extent. The number of water inlets, water injection ports, and water supply ports may be multiple.

[0061] In this embodiment, the first water pipe and the second water pipe are respectively arranged inside the tarpaulin frame 100 and the tarpaulin cover 200, so that the water channel has a semi-hidden structure. Compared with an exposed structure, this structure is more conducive to the protection of the water channel, thereby extending the service life of the water channel to a certain extent. In addition, for certain areas inside the car, such as the center area of ​​the car, the first water pipe and the second water pipe may not be able to transport water to this area in a timely and effective manner, which is not conducive to cooling and water supply in the center area of ​​the car. Therefore, the present application, through the provision of water supply pipe 230, enables the water channel to supply water to areas that the first water pipe and the second water pipe cannot supply water, thereby compensating for the defects in the water supply range of the first water pipe and the second water pipe to a certain extent, and greatly improving the uniform water supply effect of the water channel.

[0062] Furthermore, a water supply pipe 230 is located between the pair of crossbeams 210 and is connected to each of the pair of side beams 220, thereby dividing the second installation area into several sub-areas. There may be multiple water supply pipes 230, such as two or three, and the multiple water supply pipes 230 may be evenly distributed along the length of the vehicle. Users may arrange these pipes appropriately based on the size of the vehicle or tarpaulin cover 200, and this application does not impose any restrictions on this.

[0063] By setting up the water supply pipe 230, the second installation area is divided into multiple sub-areas. On the one hand, the water supply channel can supply water to the interior of the car more evenly, which is conducive to ensuring that the truck tarpaulin system evenly cools down different positions inside the car; on the other hand, the multiple sub-areas formed can accommodate multiple temperature control devices 300, so that the multiple temperature control devices 300 can more evenly supply air to the interior of the car to achieve uniform adjustment of the temperature inside the car.

[0064] Optionally, the temperature control device 300 is a fan, and there are multiple fans, and the multiple fans are evenly distributed in several sub-areas; or, the temperature control device 300 is an air conditioner, and there are multiple air conditioners, and the multiple air conditioners are evenly distributed in several sub-areas.

[0065] In some embodiments, the truck tarpaulin system also includes a water tank (not shown in the figure), a water inlet pipe (not shown in the figure) and a driving pump (not shown in the figure), the water inlet pipe is respectively connected to the first water pipe and the second water pipe, and the driving pump is respectively connected to the water tank and the water inlet pipe for transporting water from the water tank to the water inlet pipe.

[0066] In some embodiments, reference Figures 1-4 As shown, the truck tarpaulin system further includes a flap device 240 disposed on at least one of the pair of cross beams 210, and a guide portion 130 disposed on at least one of the pair of cross bars 110. The flap device 240 cooperates with the guide portion 130 to move the tarpaulin cover 200 along the extension direction of the guide portion 130 to open or close the opening.

[0067] Further, refer to Figure 2 and Figure 3 As shown, the flip cover device 240 includes an upper sliding roller 241, a lower sliding roller 242 and a fixed plate 243. The upper sliding roller 241 is located above the horizontal bar 110 and has a transmission part 244 corresponding to the guide part 130. The lower sliding roller 242 is located below the horizontal bar 110, and the fixed plate 243 is connected to the upper sliding roller 241 and the lower sliding roller 242 respectively; wherein, a movement space for the horizontal bar to pass through is formed between the upper sliding roller 241 and the lower sliding roller 242, and the transmission part 244 cooperates with the guide part 130 to realize the movement of the tarpaulin cover 200 relative to the tarpaulin frame 100.

[0068] Because the crossbars 210 of the tarpaulin cover 200 and the crossbars 110 of the tarpaulin frame 100 generally exist in pairs, the number and arrangement of the flap device 240 can be varied. For example, in one embodiment, there is one flap device 240, which can be arranged corresponding to either of the two crossbars 210; or, in another embodiment, there are two flap devices 240, each of which is arranged corresponding to a pair of crossbars 210. This application does not limit the number and arrangement of the flap devices.

[0069] In addition, the upper sliding roller 241 and the lower sliding roller 242 are components that are in direct contact with the surface of the crossbeam 210. In order to effectively reduce the friction generated between the tarpaulin cover 200 and the crossbeam 210 during the movement of the tarpaulin cover 200 along the contour of the crossbeam 210, make the relative movement between the two smoother, and reduce the noise generated during the relative movement between the two. The present application can reduce the friction between the three by providing a lubricating layer on the surface of at least one of the upper sliding roller 241, the lower sliding roller 242, and the crossbeam 210. The lubricating layer can be formed by lubricating oil, grease, etc. applied to the surfaces of the three, or can be formed by a material with a low friction coefficient such as polytetrafluoroethylene, silicone rubber, stone mill, Teflon, etc. used by the three themselves, or can be formed by a low-friction fabric, film, etc. coated on the surfaces of the three, and the present application is not limited to this.

[0070] It should also be noted that the flap device 240, which is used to drive the tarpaulin cover 200 to move along the contour of the tarpaulin frame 100, is provided with a transmission portion 244 that cooperates with the guide portion 130 to achieve relative movement between the tarpaulin cover 200 and the tarpaulin frame 100. Optionally, the cooperation between the transmission portion 244 and the guide portion 130 can be a sprocket-chain cooperation, a gear-rack cooperation, or a pulley-belt cooperation. This application does not limit the specific cooperation method between the two.

[0071] In some embodiments, reference Figure 2 and Figure 3 As shown, the flip cover device 240 also includes a pair of guide rollers 245 located on both sides of the upper sliding roller 241; when the tarpaulin cover 200 moves along the horizontal bar 110 toward the pile 120, or when the tarpaulin cover 200 moves along the pile 120 toward the horizontal bar 110, at least one of the pair of guide rollers 245 contacts the curved section of the horizontal bar 110.

[0072] The guide rollers 245 not only provide guidance during the movement of the tarpaulin cover 200 relative to the tarpaulin frame 100, allowing the tarpaulin cover 200 to more accurately follow the contour of the horizontal bar 110, but also, at least one of the two guide rollers 245 can contact the curved section of the horizontal bar 110 during the tarpaulin cover 200's flipping, thereby making the flipping process of the tarpaulin cover 200 smoother and further reducing the impact that the tarpaulin cover 200 may have on the tarpaulin frame 100. It is understood that the structure of the guide rollers 245 may be the same as or different from that of the upper sliding roller 241 and the lower sliding roller 242, and this is not limited in this application.

[0073] It should be noted that when a truck is overloaded with cargo, or when the truck is subjected to external forces during transport, the truck's frame beams are likely to deform, a phenomenon commonly known as box expansion. Once box expansion occurs, the truck's tarpaulin system, particularly the tarpaulin frame 100, located outside the truck, will deform along with the deformation of the box's frame beams. This not only compromises the structural stability of the tarpaulin frame 100 itself, but also significantly affects the smooth movement of the tarpaulin cover 200 relative to the tarpaulin frame 100, preventing the tarpaulin cover 200 from smoothly following the contours of the tarpaulin frame 100.

[0074] Based on this, in order to better solve the above problems, preferably, refer to Figure 1 and Figure 4 As shown, the tarpaulin frame 100 in the present application may further include an anti-deformation assembly 140 connected to the stakes 120 and the crossbar 110, respectively. The anti-deformation assembly 140 includes a fixed frame (not marked in the figure), a fixed seat (not marked in the figure), and a sliding member (not marked in the figure). The fixed frame has a through buffer space (not marked in the figure), and the fixed seat has a mounting groove (not marked in the figure) opening toward the fixed frame. Both ends of the sliding member can pass through the buffer space and connect to the two side walls of the mounting groove, respectively. In response to the deformation of the tarpaulin frame 100, the sliding member can limit the relative displacement between the fixed frame and the fixed seat within the buffer space. Optionally, the sliding member can be a pulley.

[0075] This structure allows relative movement between the horizontal bar 110 and the vertical stakes 120 of the tarpaulin frame 100 when the tarpaulin frame 100 is subjected to deformation from the vehicle compartment, thereby significantly reducing the stress that may be generated between the horizontal bar 110 and the vertical stakes 120, minimizing undesirable deformation of the tarpaulin frame 100 and thereby maintaining the structural stability of the tarpaulin frame 100. This approach also helps ensure the smooth movement of the tarpaulin cover 200 relative to the tarpaulin frame 100, making the tarpaulin cover 200 move more smoothly along the contour of the tarpaulin frame 100 and significantly reducing the possibility of failure of the truck tarpaulin system.

[0076] In some embodiments, the flip cover device 240 also includes a mounting seat (not shown in the figure) and a driving member (not marked in the figure), the mounting seat is connected to the fixed plate, the driving member is arranged on the mounting seat, and the driving shaft of the driving member is fixedly connected to the upper sliding roller so that the upper sliding roller can rotate synchronously with the rotation of the driving shaft.

[0077] The mounting base, as a component for securing the driver, can have various structures, such as a plate-like structure or a shell-like structure, which is not limited in this application. Furthermore, the driver can be a motor, a hydraulic pump, a pneumatic pump, a handle, a crank, etc., and this application does not limit the type of driver. Furthermore, the driver can be connected to a speed reducer to further increase its driving torque.

[0078] In some embodiments, continue to refer to Figures 1-4 As shown, the guide portion 130 is a chain respectively provided corresponding to the horizontal bar 110 and the upright stake 120 ; the transmission portion 244 is a sprocket fixed to the end of the upper sliding roller 241 and coaxial with the upper sliding roller 241 .

[0079] Compared to a chain attached only to the horizontal bar 110, the chain's alignment with both the horizontal bar 110 and the uprights 120 extends the motion path of the tarpaulin cover 200 relative to the tarpaulin frame 100, thereby improving the smoothness of the tarpaulin cover 200's reversal. Furthermore, the chain and sprocket combination offers a precise transmission ratio, reliable operation, high transmission efficiency, and a strong overload capacity, virtually preventing slippage and enabling operation in harsh environments such as high temperature, humidity, dust, and pollution.

[0080] In some embodiments, a locking member (not shown in the figure) is provided on the outer wall of the crossbeam 210, and a locking member (not shown in the figure) is provided on the surface of the crossbar 110 corresponding to the locking member; when the tarpaulin cover 200 moves along the crossbar 110, the locking member can cooperate with the locking member to limit the displacement of the tarpaulin cover 200 relative to the tarpaulin frame 100.

[0081] By providing the locking member and the locking member, when the tarpaulin cover 200 moves to the horizontal bar 110, especially when the tarpaulin cover 200 closes the opening of the tarpaulin frame 100, the vertical displacement of the tarpaulin cover 200 relative to the tarpaulin frame 100 is greatly limited, thereby improving the stability of the truck tarpaulin system. The locking member can be a locking plate with an L-shaped cross-section, and the locking member can be a locking plate with a U-shaped cross-section. The L-shaped locking plate and the U-shaped locking plate can stop and cooperate with each other in the vertical direction. It is understood that regarding the specific structure of the locking member and the locking member, those skilled in the art can implement them in a variety of different ways. For example, the locking member can also be a T-shaped plate, and the locking member can also be a locking block with a T-shaped slot. The present application does not limit the specific structure of the locking member and the locking member. Furthermore, both the locking member and the locking member can be arranged on the outer wall of one side of the beam 210 and the horizontal bar 110 only, or on the outer walls of both sides of the beam 210 and the horizontal bar 110. This application does not limit the arrangement method of the locking member and the locking member.

[0082] Regarding the specific structure of the flip cover device 240, in addition to being implemented according to the above content, it can also be implemented according to the following content; and in order to distinguish it from the above flip cover device 240, the flip cover device 240 will be renamed as a "crawling device" below. Specifically:

[0083] In some embodiments, reference Figure 5-Figure 9As shown, the tarpaulin frame 100 has a guide groove 111 formed on the cross bar 110 and a pair of guide members 112 arranged in parallel on both sides of the guide groove 111; the crawling device 250 is arranged on the tarpaulin cover 200, and the crawling device 250 includes a crawling seat 251, a transmission shaft 252, a pair of transmission members 253 and a connecting plate 254, the crawling seat 251 is fixed to the tarpaulin cover 200, the transmission shaft 252 is arranged along the center line of the crawling seat 251, a pair of transmission members 253 are coaxially arranged on the outside of the transmission shaft 252, and the pair of transmission members 253 correspond to the pair of guide members 112 respectively, the upper part of the connecting plate 254 is rotatably connected to the transmission shaft 252, and the lower part is provided with a roller 255 corresponding to the guide groove 111. Furthermore, the relative movement between the tarpaulin cover 200 and the tarpaulin frame 100 is achieved by the cooperation between the roller 255 and the guide groove 111 , and the cooperation between the pair of guide members 112 and the pair of transmission members 253 .

[0084] There are many different implementations of the specific structure of the roller 255, and this application does not limit this. For example, when the groove wall of the guide groove 111 is a plane, the roller 255 can be a cylindrical roller; or, when the groove wall of the guide groove 111 is an arc-shaped surface, the roller 255 can be an arc-shaped roller; when the groove wall of the guide groove 111 is a wedge-shaped surface, the roller 255 can be a wedge-shaped roller; when the groove wall of the guide groove 111 is a V-shaped surface, the roller 255 can be an inverted V-shaped roller.

[0085] It is understood that the roller 255, as a component that directly contacts the walls of the guide groove 111, can guide the tarpaulin cover 200 during its movement relative to the tarpaulin frame 100. To effectively reduce friction between the tarpaulin cover 200 and the tarpaulin frame 100 during movement, thereby smoothing the relative movement and reducing noise generated during this process, the present application can reduce friction between the tarpaulin cover 200 and the tarpaulin frame 100 by providing a lubricating layer on the surfaces of structures such as the roller 255, the walls of the guide groove 111, the horizontal bar 110 of the tarpaulin frame 100, or the horizontal beam 210 of the tarpaulin cover 200. Among them, the lubricating layer can be formed by lubricating oil, grease, etc. coated on the surface of the above-mentioned structures, or it can be formed by materials with low friction coefficients such as polytetrafluoroethylene, silicone rubber, stone mill, Teflon, etc. used in the above-mentioned structures themselves, or it can also be formed by low-friction fabrics, films, etc. sleeved on the surfaces of the above-mentioned structures. This application does not limit this.

[0086] In addition, the present application utilizes the coordination between the transmission member 253 and the guide member 112 to achieve relative movement between the tarpaulin cover 200 and the tarpaulin frame 100. The coordination between the transmission member 253 and the guide member 112 can be at least one of a variety of different implementations, such as a sprocket-chain coordination, a gear-rack coordination, a screw-nut coordination, or a pulley-belt coordination. The present application does not limit the specific coordination between the transmission member 253 and the guide member 112. Furthermore, since there are two transmission members 253 and two guide members 112, the two transmission members 253 and the two guide members 112 cooperate to form two transmission mechanisms. The first transmission mechanism can utilize one of the aforementioned transmission methods, while the second transmission mechanism can utilize the same or different transmission method as the first transmission mechanism. This is also not a limitation in the present application.

[0087] Regarding the arrangement of the two guide members 112 in the tarpaulin rack 100, this application will be described with the following two different examples:

[0088] Example 1

[0089] Reference Figure 5 and Figure 6 As shown, the tarpaulin rack 100 includes a horizontal bar 110 and a stake 120 connected to the horizontal bar 110. A pair of guide members 112 are spaced apart on either side of the top surface of the horizontal bar 110. A guide groove 111 is formed inside the horizontal bar 110 and passes through the top surface of the horizontal bar 110. The guide groove 111 is located between the pair of guide members 112. In this example, the placement of the guide members 112 on the top surface of the horizontal bar 110 can, to a certain extent, optimize the layout of the various components provided on the horizontal bar 110, thereby facilitating miniaturization of the equipment.

[0090] Example 2

[0091] Reference Figure 9 As shown, the tarpaulin rack 100 includes a horizontal bar 110 and a stake 120 connected to the horizontal bar 110. The two side walls of the horizontal bar 110 extend outward to form a support portion 113; a pair of guide members 112 are respectively provided on the support portion 113, and a guide groove 111 passes through the top surface of the horizontal bar 110 and is formed inside the horizontal bar 110, and the guide groove 111 is located between the pair of guide members 112. The support portion 113 can be a support plate, a support tube, etc., and this application does not limit the structure of the support portion 113. In this example, the provision of the support portion 113 can enhance the support effect on the guide member 112, thereby facilitating the improvement of the stability of the transmission mechanism.

[0092] In some embodiments, reference Figure 7 and Figure 8As shown, the crawling device 250 may further include a pair of guide rollers 256 rotatably connected to the crawling seat 251, and the pair of guide rollers 256 are located on both sides of the transmission member 253. Optionally, the two guide rollers 256 may be located on the left and right sides of the transmission member 253 in the horizontal direction; or the two guide rollers 256 may be located on the upper and lower sides of the transmission member 253 in the vertical direction.

[0093] The guide rollers 256 not only provide guidance during the movement of the tarpaulin cover 200 relative to the tarpaulin frame 100, allowing the tarpaulin cover 200 to more accurately follow the contour of the crossbar 110, but also, when the two guide rollers 256 are arranged horizontally, they can contact the guide member 112 or the top surface of the crossbar 110 during the tarpaulin cover 200's turnover. When the two guide rollers 256 are arranged vertically, at least one of the two guide rollers 256 can contact the bottom or top surface of the crossbar 110 during the tarpaulin cover 200's turnover, thereby making the tarpaulin cover 200's turnover process smoother and further reducing the impact that the tarpaulin cover 200 may have on the tarpaulin frame 100. It is understood that the structure of the guide rollers 256 may be the same as or different from that of the rollers 255, and this is not limited in this application.

[0094] Furthermore, a gap (not marked in the figure) is formed between the pair of guide rollers 256 , and the gap is used to limit the rotation radius of the connecting plate 254 relative to the transmission shaft 252 .

[0095] Because the upper and lower portions of the connecting plate 254 are connected to the transmission shaft 252 and roller 255, respectively, the friction between the roller 255 and the guide groove 111 and the driving force exerted by the transmission member 253 on the guide member 112 are in opposite directions. As the tarpaulin cover 200 moves along the contour of the tarpaulin frame 100, this connection structure is likely to cause the connecting plate 254 to deflect to a certain extent relative to the crawler seat 251. If the guide roller 256 were not used to limit the deflection of the connecting plate 254, interference between the roller 255 and the guide groove 111 would likely occur, thereby hindering the normal operation of the crawler device 250 and, in turn, causing the relative movement between the tarpaulin cover 200 and the tarpaulin frame 100 to fail.

[0096] In view of this, the present application limits the rotation radius of the connecting plate 254 relative to the transmission shaft 252 by using the gap formed between the pair of guide rollers 256, thereby ensuring the smooth operation of the crawling device 250 and further achieving stability in the relative movement between the tarpaulin cover 200 and the tarpaulin frame 100. The specific size of the gap between the two guide rollers 256 can be reasonably set according to the size of the connecting plate 254, and this application does not impose any restrictions on this.

[0097] Further, continue to refer to Figure 7 and Figure 8 As shown, the crawling device 250 also includes a driver 257 connected to the transmission shaft 252; wherein, the driver 257 can be a motor, a hydraulic pump, a pneumatic pump, a handle, a crank, etc., and this application does not limit the type of the driver 257.

[0098] In addition, an embodiment of the present invention also provides a truck compartment, including a compartment body (not shown in the figure) and the above-mentioned truck tarpaulin system. By arranging the truck tarpaulin system on the outside of the compartment body, the transportation environment inside the compartment body can be greatly improved, which is beneficial to the transportation of livestock.
