Description

Technical Field

[0001] The utility model relates to the technical field of truck tarpaulins, in particular to a tarpaulin structure for a high-rail truck. Background Art

[0002] When transporting goods, especially slag and rocks, trucks must cover the roof with tarpaulins to ensure transportation safety and reduce environmental pollution. Truck tarpaulins mainly use tarpaulin covering mechanisms to retract the tarpaulin.

[0003] Chinese patent application number 202221928140.1 discloses a covering device for a truck compartment, including a awning folding drive mechanism, a awning covering drive mechanism, a tarpaulin and a door frame, etc. The door frame can be rotatably installed on the truck compartment, one end of the tarpaulin is fixed to the truck, and the other end is fixed to the cross bar of the door frame. The awning folding drive mechanism is connected to the door frame through a awning folding rope arranged above the tarpaulin to drive the door frame to rotate in the direction of folding the tarpaulin, thereby folding the tarpaulin, and the awning covering drive mechanism is connected to the door frame to drive the door frame to rotate in the direction of covering the tarpaulin so that the tarpaulin covers the truck compartment. However, in order to facilitate loading and unloading of goods on trucks, tarpaulin support is generally not provided on the top of the truck compartment. After the tarpaulin is covered on the truck compartment, it is mainly supported by the side panels on both sides of the truck compartment. After the tarpaulin is covered on the truck compartment, a flat area is formed above the truck compartment. In addition, the tarpaulin material is relatively soft and easily deformed, which causes the tarpaulin to easily accumulate water on rainy days, making the tarpaulin heavier, which not only increases the difficulty of folding the tarpaulin, but also easily causes the tarpaulin to be torn during the folding process. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tarpaulin structure for a high-sided truck, so as to solve the problem that water easily accumulates after the tarpaulin is covered.

[0005] The utility model solves the technical problem by adopting the following technical solutions: a high-rail truck tarpaulin structure comprises a tarpaulin and a track for collecting the tarpaulin which is arranged above the truck compartment and extends along the length direction of the truck compartment;

[0011] Furthermore, the track is composed of two ropes arranged upper and lower, and the upper ends of the lifting ears are slidably connected to the upper and lower ropes of the track.

[0012] Furthermore, the lifting ears are in two rows and are respectively arranged at both ends of the arc-shaped support. The rails are also in two rows and are arranged in a one-to-one correspondence with the two rows of lifting ears. The lifting ears are slidably connected to the corresponding rails.

[0013] Furthermore, the arc-shaped support is an elastic member, and the lifting ear is provided at a middle position between two ends of the arc-shaped support, so that the middle position of the arc-shaped support is pulled and arched upward to form an arc shape.

[0014] Furthermore, the arc-shaped support is formed by elastic bending of an elastic member, and one end of the arc-shaped support is provided with a pull rope whose one end is connected to the other end of the arc-shaped support.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 、 Figure 2 As shown, the high-rail truck tarpaulin structure of the present invention includes a tarpaulin 1 and a tarpaulin-retracting track 5 disposed above a truck compartment 4 and extending along the length of the truck compartment 4. A plurality of downwardly curved supports 2 are disposed at intervals along the length of the tarpaulin 1 on the underside of the tarpaulin 1. The supports 2 are fixed to the tarpaulin 1 to form an arched shape. The tarpaulin 1 is provided with at least one row of lifting lugs 7 arranged in a straight line along the length of the tarpaulin 1, with each row of the lifting lugs 7 corresponding one-to-one with the curved supports 2. The tarpaulin 1 is suspended from the track 5 by the lifting lugs 7, and the lifting lugs 8 are slidably connected to the track 5. Each row of the lifting lugs 7 corresponds one-to-one with the curved supports 2, i.e., one lifting lug 7 is disposed at each location where the curved supports 2 are disposed.

[0027] In the present invention, a plurality refers to at least two.

[0028] Since the lifting lug 7 is slidably connected to the track 5, when the tarpaulin needs to be unfolded or folded, one end of the tarpaulin is pulled to move the lifting lug 7 toward or away from the tarpaulin, so that the tarpaulin can be folded or unfolded to cover the truck compartment.

[0029] like Figure 1 and Figure 2As shown, the high-rail truck tarpaulin structure of the present invention is provided with a plurality of arc-shaped supports 2 that are bent downward and fixed on the tarpaulin 1 at intervals on the lower side of the tarpaulin 1 along the length direction of the tarpaulin 1 so that the tarpaulin 1 is arched, and the tarpaulin 1 is provided with at least one row of lifting ears 7 that are arranged in a straight line along the length direction of the tarpaulin 1, and the lifting ears 7 in each row are arranged in a one-to-one correspondence with the arc-shaped supports 2. The tarpaulin 1 is hung on the track 5 through the lifting ears 7, and the lifting ears 7 are slidably connected to the track 5. In this way, when the truck tarpaulin is unfolded to cover the truck compartment 4, the weight of the arc-shaped supports 2 can be borne by the tarpaulin retraction rope 5, so that the arc-shaped supports 2 can support the tarpaulin 1, so that the tarpaulin is arched and covers the truck compartment, which is convenient for drainage of the tarpaulin, the tarpaulin is not easy to accumulate water, and the service life of the tarpaulin is longer. Since the arc supports 2 are fixed at intervals on the tarpaulin 1, they will not affect the folding of the tarpaulin 1, and when the tarpaulin is folded, the arc supports 2 will also move closer. The arc supports 2 will not affect the loading and unloading of goods by the truck, and there is no need to remove the arc supports 2 separately.

[0030] It is understandable that the smaller the spacing between the arc supports 2 is, the more beneficial it is for supporting the tarpaulin 1. However, if the spacing is too small, the tarpaulin 1 will occupy a larger area after being folded. Taking all factors into consideration, in the present invention, the spacing between the arc supports 2 is preferably in the range of 400 to 800 mm. In order to prevent the tarpaulin from sagging between the arc supports 2, as shown in FIG. Figure 1 As shown, auxiliary lugs 8 fixed to the tarpaulin 1 can be provided between adjacent lugs 7 in the same row, and the upper ends of the auxiliary lugs 8 are slidably connected to the rails 5. After providing the auxiliary lugs 8, the spacing between the arc supports 2 can be appropriately increased, thereby reducing manufacturing costs.

[0031] like Figure 3 As shown in FIG. 1 , in the present embodiment, the lug 7 is slidably connected to the track 5 through a hole that is slidably matched with the track 5. Figure 4 As shown, in order to facilitate sliding, a rotating wheel 72 is provided in the hole where the lifting ear 7 is slidably connected to the track 5.

[0032] Specifically, the arc support 2 can be fixed to the tarpaulin 1 by bonding, bundling, riveting, bolting, etc. In the embodiment of the present utility model, Figure 2 and Figure 3 As shown, the lower end of the ear 7 is provided with a clamping mechanism 71, and the arc support 2 is clamped and fixed on the tarpaulin 1 through the clamping mechanism 71. The clamping mechanism 71 can adopt various existing openable and closable clamping mechanisms, such as: a spring clamp mechanism or a clamping mechanism locked by a bolt (such as Figure 3As shown). The arc support 2 is fixed to the tarpaulin 1 by a clamping mechanism 71, and the disassembly and installation of the arc support 2 is more convenient. It is not only convenient to replace the arc support 2 when it is damaged, but more importantly, it will not cause damage to the tarpaulin, which is beneficial to ensuring the service life of the tarpaulin. In addition, because the clamping mechanism 71 is set at the lower end of the lifting ear 7 and clamps the arc support 2, the track 5 can directly transmit the supporting force to the arc support 2 through the lifting ear, and the arc support 2 then supports the tarpaulin 1. Compared with the method of directly gluing or fixing the lifting ear 7 to the tarpaulin 1, the tarpaulin 1 of the above structure is better stressed and less prone to damage, which is beneficial to improving the service life of the tarpaulin. In order to make the arc support 2 more firmly fixed, an additional clamping mechanism can be provided on the arc support 2 as needed to fix the arc support 2.

[0033] In the present invention, the specific number of rails 5 can be one or more, and the number of rows of lugs can be one or more. The number of rails 5 and the number of rows of lugs can be set as needed. The number of rows of lugs is generally consistent with the number of rails, and the two are set in a one-to-one correspondence. In the embodiment of the present invention, Figure 2 As shown, the lugs 7 are in two rows, respectively arranged at both ends of the arc-shaped support 2 , and the rails 5 are also in two rows and are arranged in one-to-one correspondence with the two rows of lugs 7 , and the lugs 7 are slidably connected to the corresponding rails 5 .

[0034] The arc-shaped support can be made of a non-elastic member or an elastic member. When the arc-shaped support is made of an elastic member, the arc-shaped support can be formed into an arc by the elastic member undergoing plastic deformation and bending. In one embodiment of the present invention, the arc-shaped support 2 is an elastic member, and the lifting lug 7 is arranged in the middle position between the two ends of the arc-shaped support 2. In this way, the middle position of the arc-shaped support 2 is subjected to the upward pulling force of the track 5. In this way, the middle position of the arc-shaped support 2 is pulled and elastically deformed, thereby arching upward to form an arc shape. The above structure provides an outward prestressed force inside the arc-shaped support, making the upper part of the arc-shaped support less likely to deform when under pressure, and having better strength, which is more conducive to supporting the tarpaulin. When the lifting lug 7 is arranged in the middle position between the two ends of the arc-shaped support 2, the number of rows of lifting lugs 7 can be one or more, and the track 5 can be one or more. Typically, there are two rows of lifting lugs and two tracks, and the tracks are arranged in a one-to-one correspondence with the two rows of lifting lugs.

[0035] The track can be made of hard rails or ropes. The hard rails can be made of rods such as steel rails, iron pipes, etc. In order to save costs, Figure 1 In the embodiment, the track is a rope having one end connected to the front end of the freight car 4 and the other end connected to the rear end of the freight car 4. That is, the track is composed of ropes. Figure 1 and Figure 5As shown, the track 5 is composed of two ropes arranged upper and lower, and the upper ends of the lifting ears 7 are slidably connected to the upper and lower ropes of the track 5. This can reduce the sagging amplitude of the middle part between the two ends of the tarpaulin after it is unfolded.

[0036] When the lifting lugs 7 are arranged in two rows and are respectively arranged at both ends of the arc-shaped support 2, in the embodiment of the present utility model, as Figure 2 As shown, the curved support 2 is also formed by elastic bending of an elastic member. A pull cord 3 is provided at one end of the curved support 2, connected to the other end of the curved support 2, to maintain its curvature. This structure also creates an outward prestressed force within the curved support, making the upper portion of the curved support less susceptible to deformation when under pressure, and providing greater strength, which is more conducive to supporting the tarpaulin.

[0037] The arc support 2 can be made of elastic materials such as steel wire, carbon rod, fiberglass rod, etc. In the present invention, the arc support is preferably made of fiberglass rod, which has low procurement cost and is lighter while meeting the strength requirements, adding less weight to the tarpaulin, which is conducive to ensuring the service life of the tarpaulin.

[0038] The pull rope 3 can be made of nylon rope, steel rope, etc. The pull rope 3 can be connected to the two ends of the arc support 2 in a detachable manner. Of course, it can also be connected to the two ends of the arc support 2 in a non-detachable manner such as welding. In the present invention, preferably, the pull rope 3 is detachably connected to the two ends of the arc support 2. In this way, when there are many trucks, the pull rope can be removed so that the truck can load more cargo (the cargo can be higher than the position of the pull rope). The pull rope 3 can be detachably connected to the two ends of the arc support 2 by bundling, bolting, etc. Figure 6 As shown, in order to facilitate the disassembly of the pull rope, it is best that the pull rope 3 is hooked to the two ends of the arc support 2 through a hook 31. The pull rope 3 and the hook 31 can be connected by welding, bundling, etc.

[0039] like Figure 2 As shown, in order to make the tarpaulin 1 cover the truck compartment better, the edge of the tarpaulin 1 is penetrated with a tightening rope 6. The tightening rope 6 can be used to tighten the edge opening of the truck tarpaulin so that it fits on the truck compartment.

[0040] In order to facilitate the folding and covering of the tarpaulin, the present invention is also provided with a folding mechanism. The folding mechanism includes a motor and a folding rope. The folding rope is wound around a roller, and its two ends are respectively connected to one end of the tarpaulin. The motor is in transmission connection with the roller. When the motor rotates in one direction, the folding rope can be driven by the roller, so that the folding rope pulls the tarpaulin in one direction to unfold the tarpaulin. When the motor is reversed, the folding rope can be pulled in the opposite direction to fold the tarpaulin. When the track 5 is a rope, such as Figure 1In the figure, the awning-collecting rope 9 is connected to the track 5 to form a ring, and the two ends of the track are respectively tensioned on the rollers 41 at both ends of the truck compartment. In this way, the track 5 also serves as a part of the awning-collecting rope, and the awning-collecting rope also serves as a part of the track.

[0041] In order to facilitate the adjustment of the height of the tarpaulin according to the needs, such as Figure 1 As shown, in the present invention, the truck compartment 4 is provided with a lifting mechanism 10 for adjusting the height of the track 5, and the track 5 is mounted on the lifting mechanism 10. The lifting mechanism 10 can employ various existing lifting mechanisms, such as a hydraulic cylinder, a pneumatic cylinder, an electric screw, a rack and pinion lifting mechanism, and the like. When a large amount of cargo is loaded, the lifting mechanism can raise the height of the track 5, thereby raising the height of the tarpaulin accordingly, thereby allowing the truck to carry more cargo.
