Description

Technical Field

[0001] This utility model relates to the field of truck tarpaulin support technology, specifically a truck tarpaulin steel rope track support and a truck tarpaulin steel rope track installation structure. Background Technology

[0002] In road freight transport using bulk cargo trucks, tarpaulins are needed to cover the goods to prevent them from getting wet, blown by the wind, or falling off due to bumps. Currently, one installation method for truck tarpaulins, especially for high-sided trucks, is as follows: the tarpaulin is slidably installed on rails above the truck bed. The rails bear the weight of the tarpaulin, and the front end of the tarpaulin is fixedly connected to the truck bed. By using a motor or manual pulling, the rear end of the tarpaulin slides along the rails to either fold up at the front of the truck bed or unfold to cover the truck bed. There are usually two rails, symmetrically arranged on both sides of the centerline of the truck bed. The rails are typically formed by rods or steel cables. Steel cables are more commonly used due to their advantages such as low cost, lighter weight, and longer service life.

[0003] To better control the shape of the tarpaulin and avoid the problem of the top and middle of the tarpaulin collapsing during use, the tarpaulin track is now usually set above the middle of the truck bed.

[0004] However, in practice, when loading and unloading goods, especially hoisting goods, there are situations where goods need to pass over the truck bed. If the track is located above the middle of the truck bed, it will affect the loading and unloading process. Therefore, it is necessary to remove the track from above the truck bed when it obstructs loading and unloading to improve efficiency. Regarding the use of steel cables for tarpaulin tracks, the cables are currently connected to supports at the front and rear ends of the truck bed via cable clips. This method requires adjusting the cable length by tightening bolts on the cable clips when removing the steel cable track, which not only makes it difficult to quickly remove the track from above the truck bed but also makes reinstallation cumbersome. Furthermore, once the steel cables are removed, the tarpaulin, no longer supported by the track, will fall into the truck bed, making subsequent cable installation difficult and laborious. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a truck tarpaulin steel rope track bracket and truck tarpaulin steel rope track installation structure that is convenient for both removing the steel rope track from the top of the truck car and reinstalling it.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a truck tarpaulin steel rope track bracket, including a front bracket installed at the front end of the truck body and a rear bracket installed at the rear end of the truck body;

[0007] At least one steel cable front connecting rod is installed on the front support, which is arranged along the length of the truck bed. The rear end of the steel cable front connecting rod protrudes towards the rear of the truck bed to form a tarpaulin support part.

[0008] The rear support is provided with a rotating shaft that can rotate around its own axis. The rotating shaft is arranged along the width direction of the truck bed. The rotating shaft is provided with hooks that correspond one-to-one with the front connecting rod of the steel rope.

[0009] The rear bracket is also provided with a self-locking mechanism connected to the rotating shaft to prevent the rotating shaft from rotating on its own in one of its rotational directions.

[0010] Furthermore, the self-locking mechanism includes a ratchet and a pawl, the ratchet being mounted on the rotating shaft and the pawl being mounted on the rear bracket and cooperating with the ratchet.

[0011] Furthermore, the front connecting rod of the steel rope is a steel pipe.

[0012] Furthermore, there are two steel rope front connecting rods, which are symmetrically arranged on both sides of the centerline of the truck body.

[0013] Furthermore, the front support is provided with a crossbar extending along the width direction of the truck bed, and the front steel cable connecting rod is installed on the crossbar and can rotate upward around the axis of the crossbar.

[0014] Furthermore, the crossbar is rotatably engaged with the front support, and the front connecting rod of the steel rope is fixedly connected to the crossbar.

[0015] Furthermore, the front support is provided with a spring that is connected to the front connecting rod of the steel rope to generate a force that pushes the front connecting rod of the steel rope to rotate upward about the axis of the crossbar.

[0016] The truck tarpaulin steel rope track installation structure includes a steel rope and the aforementioned truck tarpaulin steel rope track bracket. The front end of the steel rope is connected to the rear end of the front connecting rod of the steel rope, and the rear end is hooked onto the hook corresponding to the front connecting rod of the steel rope, and wound around the rotating shaft, thereby tensioning to form the steel rope track.

[0017] The beneficial effects of this utility model are as follows: The truck tarpaulin steel rope track bracket and truck tarpaulin steel rope track installation structure of this utility model facilitate the removal of the steel rope track from above the truck bed. At the same time, because a tarpaulin-collecting support part is provided, the tarpaulin can be slid onto the tarpaulin-collecting support part via the steel rope track, and then supported by the tarpaulin-collecting support part. After the steel rope is removed from above the truck bed, it will not affect the tarpaulin. The next time the steel rope is installed, it is also easier and less strenuous, making it easier to reinstall and more convenient to use. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 6As shown, the steel rope track support for a truck tarpaulin of this utility model includes a front support 2 installed at the front end of the truck bed 1 and a rear support 3 installed at the rear end of the truck bed 1. The front support 2 is equipped with at least one steel rope front connecting rod 4 arranged along the length of the truck bed 1. The rear end of the steel rope front connecting rod 4 protrudes towards the rear of the truck bed 1 to form a tarpaulin-supporting part 41 for supporting the folded tarpaulin. The length of the folded tarpaulin-supporting part 41 is set according to the length of the tarpaulin 7 after folding. The rear support 3 is provided with a rotating shaft 5 that can rotate around its own axis. The rotating shaft 5 can rotate clockwise or counterclockwise around the axis. The rotating shaft 5 is arranged along the width direction of the truck bed 1, and the rotating shaft 5 is provided with hooks 51 corresponding to the steel rope front connecting rods 4. The rear support 3 is also provided with a self-locking mechanism connected to the rotating shaft 5 to prevent the rotating shaft 5 from rotating in one of its rotational directions. The direction of rotation can be either clockwise or counterclockwise.

[0029] It should be noted that the rear bracket 3 and the rear support 3 of this utility model can be non-liftable brackets made of profiles welded together, or various existing lifting brackets can be used.

[0030] The self-locking mechanism can be any existing self-locking mechanism. For example... Figure 5 As shown in the embodiment of this utility model, the self-locking mechanism adopts a ratchet mechanism, including a ratchet 52 and a pawl 31. The ratchet 52 is mounted on the rotating shaft 5, and the pawl 31 is mounted on the rear bracket 3 and cooperates with the ratchet 52.

[0031] Understandably, the pawl 31 can be provided with a spring to maintain its engagement with the ratchet 52. This is the existing structure and will not be elaborated upon here.

[0032] Because the worm gear mechanism can achieve bidirectional self-locking, it can also prevent the shaft 5 from rotating in one of its rotational directions. Therefore, in some embodiments, the self-locking mechanism includes a worm and a turbine, the turbine being mounted on or driven to the shaft 5, and the worm being mounted on the rear support 3 and meshing with the worm.

[0033] The specific number of steel rope front connecting rods 4 can be one or more, depending on the design quantity of the steel rope tracks for the tarpaulin. The specific position of the steel rope front connecting rods 4 is determined by the specific placement of the steel rope tracks. Typically, two steel rope tracks symmetrically arranged on both sides of the centerline of the truck bed 1 can better support the tarpaulin. Therefore, in this invention, preferably, there are two steel rope front connecting rods 4, symmetrically arranged on both sides of the centerline of the truck bed 1, to facilitate the installation of two steel rope tracks.

[0034] The self-locking mechanism is described using ratchet 52 and pawl 31. When using the truck tarpaulin steel rope track support of this utility model, first connect the front end of the steel rope 6 to the rear end of the steel rope front connecting rod 4, then hang the rear end of the steel rope 6 on the corresponding hook 51. Finally, rotate the rotating shaft 5 to wind the steel rope 6 around it, tensioning it to form a steel rope track extending linearly along the length of the truck bed. The specific rotation direction of the rotating shaft 5 is determined by the self-locking direction of the self-locking mechanism. For example, if the self-locking direction of the self-locking mechanism is counterclockwise rotation of the rotating shaft 5, then the rotating shaft 5 should be rotated clockwise. After the steel rope 6 is tensioned to form the steel rope track, the pawl 31, in cooperation with the ratchet 52, prevents the ratchet and rotating shaft 5 from rotating in opposite directions, thus keeping the steel rope 6 always taut. When the cable track interferes with cargo loading and unloading and needs to be removed from above the truck bed, release the pawl 31, and rotate the shaft 5 in the opposite direction to release the cable. Then, the rear end of the cable can be easily and conveniently removed from the hook 51. Removing the rear end of the cable from the hook 51 removes the cable track from above the truck bed. When the cable track needs to be reused, attach the rear end of the cable 6 to the hook 51, and rotate the shaft 5 in the direction the ratchet 52 can rotate to tension the cable 6.

[0035] If the self-locking mechanism is a worm gear mechanism, since the worm gear mechanism can achieve bidirectional self-locking, when tensioning the steel rope 6, the shaft can be rotated in either direction via the worm gear (it can rotate counterclockwise or counterclockwise). When the steel rope track affects the loading and unloading of goods and needs to be removed from above the truck bed, the shaft can be rotated in the opposite direction via the worm gear.

[0036] In this invention, the self-locking mechanism is preferably a ratchet 52 and a pawl 31 mechanism, which has a lower cost.

[0037] This utility model provides a steel cable track bracket for truck tarpaulins, facilitating the removal and reinstallation of the steel cable track from above the truck bed. Furthermore, due to the inclusion of a tarpaulin-collecting support part 41, the tarpaulin 7 can slide along the steel cable track onto the tarpaulin-collecting support part 41, and then be supported by it (see...). Figure 1 In this way, after the steel cable is removed from the top of the truck bed, it will not affect the folding of the tarpaulin, and the next time the steel cable is installed, it will be easier and less strenuous to install.

[0038] The front connecting rod 4 of the steel rope can be a solid or hollow rod, and the material can be steel or other existing materials with good strength. The steel rope can be connected to the front connecting rod 4 by binding, welding, or other methods. In this utility model, the front connecting rod 4 of the steel rope is a steel pipe. The front connecting rod 4 of the steel rope is a steel pipe, which not only has good strength and is easy to obtain, but more importantly, the steel pipe has a hollow structure, and the steel rope can be threaded and connected inside the front connecting rod 4, making it easier to install the steel rope 6 on the front connecting rod 4. Specifically, during installation, it is only necessary to set a large head 61 at the front end of the steel rope 6 with an inner diameter larger than the inner diameter of the front connecting rod 4, and then pass the rear end of the steel rope through the inner cavity of the front connecting rod 4 to achieve the front end installation of the steel rope. The large head 61 can be formed by knotting the steel rope 6. The inner diameter of the front connecting rod 4 of the steel rope is generally adapted to the outer diameter of the steel rope 6.

[0039] like Figure 6 , Figure 7 and Figure 8 As shown, further, the front support 2 is provided with a crossbar 21 extending along the width direction of the truck bed 1, and the steel cable front connecting rod 4 is installed on the crossbar 21 and can rotate upward around the axis of the crossbar 21. Figure 8 As shown, when the folded tarpaulin also obstructs the loading and unloading of goods by the truck, the crossbar 21 can be flipped upwards to flip the crossbar 21 and the tarpaulin to the front of the truck bed, thus making it easier for the truck to load and unload goods.

[0040] Specifically, the following two structures can be used to install the front connecting rod 4 of the steel rope on the crossbar 21, allowing it to rotate upwards around the axis of the crossbar 21: The first method is that the crossbar 21 is fixedly installed on the front bracket 2, and the crossbar 21 is inserted into the front connecting rod 4 of the steel rope, with the front connecting rod 4 of the steel rope and the crossbar 21 in a transmission connection; the second method is that the crossbar 21 is rotatably connected to the front bracket 2, and the front connecting rod 4 of the steel rope is fixedly connected to the crossbar 21 (see...). Figure 7 Fixed connections can be achieved through welding, bolting, or other methods.

[0041] When there are multiple steel rope front connecting rods 4, the steel rope front connecting rods 4 can share a common crossbar 21, or each can be set up with an independent crossbar 21. Figure 7 In the middle, the front connecting rod 4 of the steel rope shares a common crossbar 21.

[0042] Furthermore, such as Figure 7As shown, the front bracket 2 is equipped with a spring 22 connected to the front connecting rod 4 of the steel rope, which generates a force to push the front connecting rod 4 of the steel rope upwards about the axis of the crossbar 21. When the front connecting rod 4 of the steel rope is flipped upwards, the spring 22 provides part of the force that causes the front connecting rod 4 of the steel rope to flip upwards about the axis of the crossbar 21, thus making it easier and less strenuous to flip the front connecting rod 4 upwards. When the front connecting rod 4 of the steel rope flips back to its original position, the spring 22 deforms, thereby causing the spring 22 to generate a force again to push the front connecting rod 4 of the steel rope to flip upwards about the axis of the crossbar 21, so that it can be flipped again. The spring 22 can be a tension spring, a compression spring, or a torsion spring, etc. Figure 7 In the middle, spring 22 is a torsion spring, which is sleeved on the crossbar 21. One end of the torsion spring abuts against the front bracket 2, and the other end abuts against the front connecting rod 4 of the steel rope.

[0043] This utility model also provides a truck tarpaulin steel cable track installation structure, including a steel cable 6 and the aforementioned truck tarpaulin steel cable track bracket. The front end of the steel cable 6 is connected to the rear end (facing the rear end of the truck bed) of the front connecting rod 4, and the rear end is hooked onto the hook 51 corresponding to the front connecting rod 4, and wound around the rotating shaft 5 to form the steel cable track. During winding, rotating the rotating shaft 5 in the rotatable direction of the ratchet 52 will wind the steel cable 6 onto the rotating shaft 5. When the steel cable track affects the loading and unloading of goods and needs to be removed from above the truck bed, rotating the rotating shaft 5 in the opposite direction will release the steel cable, and the rear end of the steel cable can be easily and conveniently removed from the hook 51. Then, removing the rear end of the steel cable from the hook 51 will remove the steel cable track from above the truck bed.
