Description
Technical Field
[0001] The utility model belongs to the technical field of truck tarpaulin brackets, and in particular relates to a tarpaulin lifting bracket for trucks. Background Art
[0002] Trucks are the main vehicles used to transport building materials, equipment, and goods. To prevent the goods in the compartment from being damaged or to prevent dust from being blown into the air and causing environmental pollution, it is usually necessary to cover the top and sides of the compartment with tarpaulins. Tarpaulins are widely welcomed by truck drivers for their low cost and good wind and sun protection.
[0003] The existing method of covering truck tarpaulins is mostly manual operation, where people climb onto the car body and cover the tarpaulin with ropes. There are also some retractable awnings on the market, but the structure can only move forward and backward, and its function is relatively simple. It also limits the loading height of goods. In addition, this retractable awning has a complex structure and a high cost. Truck drivers are more willing to choose the troublesome but economical manual tarpaulin covering method.
[0004] Usually when loading goods, it is necessary to select appropriate brackets and tarpaulins according to the height of the goods. This requires preparing multiple sets of brackets and tarpaulins, which are troublesome to replace and inconvenient to use, and it is difficult to meet the requirements of current truck drivers. Moreover, on rainy days, due to the different heights of the goods in the car, the tarpaulin accumulates water after being rained on, forming different potholes. This accumulated water is not only difficult to drain, but also increases the vehicle load and increases the vehicle energy consumption, thus bringing inconvenience to transportation.
[0005] Therefore, we propose a tarpaulin lifting bracket for trucks to solve the above technical problems. Utility Model Content
[0006] In order to solve the technical problems in the above-mentioned prior art that when loading goods on a truck, it is necessary to replace the appropriate bracket and tarpaulin according to the height of the goods, which is inconvenient to use and accumulates into water after rain, increasing the energy consumption of the vehicle, the utility model proposes a tarpaulin lifting bracket for a truck.

[0009] By adopting the above technical scheme, the utility model is installed on the truck compartment, and the awning frame is installed on the front and rear sides of the compartment and connected by a connecting rod to provide support when covering the tarpaulin. When in use, the height of the base and the folding rod can be adjusted by the lifting structure, so as to effectively adapt to the height of the loaded goods, and there is no need to replace the bracket or the tarpaulin. This can not only reduce the operating burden of the truck driver, but also improve the safety and stability of loading goods, which is conducive to meeting the use needs of the truck driver. The inclination adjustment component can make the two ends of the folding rod slide on the base, so as to adjust the height of the folding rod. By increasing the height of the folding rod on rainy days, The heavier the rain, the higher the awning is lifted, which makes the surface of the awning form a slope inclined to both sides, which is conducive to draining rainwater from both sides on rainy days, avoiding water accumulation and increasing the load on the vehicle, thereby effectively reducing the vehicle's energy consumption and facilitating transportation. On sunny days, the vehicle's wind resistance coefficient can be reduced by lowering the awning height, thereby reducing the wind resistance encountered by the vehicle when driving, thereby improving the vehicle's fuel economy and driving efficiency, which can reduce transportation costs and help increase the income of truck drivers. Moreover, the utility model has a simple structure and low cost, and at the same time, the tarpaulin has the functions of lifting and draining, which is an economical and affordable choice for truck drivers.
[0010] In a further technical solution, the folding rod includes a first folding rod and a second folding rod, the proximal ends of the first folding rod and the second folding rod are connected by hinges, and the distal ends of the first folding rod and the second folding rod are respectively slidably arranged on both sides of the base.
[0011] By adopting the above technical solution, the folding rod is cooperated with the first folding rod, the second folding rod and the hinge, and the far ends of the first folding rod and the second folding rod are respectively slidably set on both sides of the base. The hinge connection can ensure that the first folding rod and the second folding rod remain symmetrical and stable during use, so that the operation of adjusting the height of the tarpaulin is smoother and more stable.
[0012] In a further technical solution, the base is a channel steel, the opening of the channel steel is set upward, and the first and second slide grooves are respectively opened on both sides of the channel steel. The ends of the first folding rod and the second folding rod are respectively provided with a first slider and a second slider, and the first slider and the second slider are respectively slidably set in the first slide groove and the second slide groove.
[0013] By adopting the above technical solution, the base of the channel steel provides supporting strength and stability, making the bracket more sturdy and reliable during use. Through the setting of the first slider, the second slider, the first slide groove and the second slide groove, the sliding of the folding rod is smoother, the operation is simple, and the structure is simple, which reduces the cost and difficulty of maintenance and repair.
[0014] In a further technical solution, a fixed end and a winding end are respectively provided below the two ends of the folding rod, and the inclination adjustment assembly includes a first self-locking reel and a first rope body, the first self-locking reel is installed on the frame on the same side as the fixed end, one end of the first rope body is fixedly connected to one end of the folding rod through the fixed end, and the other end is slidably connected to the other end of the folding rod through the winding end and turns, and after turning, it is connected to the first self-locking reel on the same side of the fixed end.
[0015] By adopting the above technical solution, through the setting of the fixed end, the winding end and the inclination adjustment component, on rainy days, the truck driver only needs to reel in the first rope body by rotating the first self-locking reel. The first rope body respectively gives an inward force to the fixed end and the winding end of the folding rod, so that both ends of the folding rod slide inward, thereby easily increasing the lifting height of the folding rod. After the adjustment is completed, the first self-locking reel can lock the position of the first rope body, thereby locking the lifting height of the folding rod, which is convenient for drainage on rainy days, while the operation is opposite on sunny days. The whole operation process is simple and convenient, which improves the efficiency of use.

[0017] By adopting the above technical solution, the use of two columns can provide a more uniform supporting force, thereby enhancing the stability of the bracket. The connection points between the columns and the base are arranged below both sides of the base, which can effectively disperse the load and ensure the balance of the supporting structure, making the bracket more stable and reliable during use. Through the sliding connection between the columns and the lifting and adjusting mechanism, the truck driver can easily control the lifting and lowering of the bracket and the tarpaulin, which is convenient for loading goods.

DETAILED DESCRIPTION
[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0044] Embodiment 1:
[0045] See also Figure 1 The present embodiment provides a tarpaulin lifting bracket for a truck, comprising two sets of tarpaulin frames and three connecting rods 1, wherein the tarpaulin frames are symmetrically arranged on the front and rear sides of the vehicle compartment, wherein the tarpaulin frames include a supporting structure and a lifting structure, wherein the supporting structure includes a base 2 and a folding rod, wherein the middle portion of the folding rod is rotatable, and the two ends of the folding rod are respectively slidably arranged on the two sides of the base 2, and the folding rod is connected with an inclination adjustment assembly for controlling the two ends of the folding rod to slide on the base 2, and the lifting structure is used to be installed on the vehicle frame, and the telescopic end of the lifting structure is connected to the bottom of the base 2 and can make the base 2 rise and fall, and the connecting rods 1 are arranged on the folding rods at intervals, and the two ends of each of the connecting rods 1 are respectively connected to the folding rods on the front and rear sides.
[0046] Specifically, the height of the bracket can be adjusted through the lifting structure, that is, the height of the tarpaulin can be effectively adjusted, so as to effectively adapt to the height of the loaded goods, and there is no need to replace the bracket or the tarpaulin. This can not only reduce the operating burden of the truck driver, but also improve the safety and stability of loading goods, which is conducive to meeting the use needs of the truck driver; and the lifting height of the folding rod can be adjusted by the inclination adjustment component, so that the awning can form a slope inclined to both sides on rainy days, which is conducive to draining rainwater from both sides on rainy days, avoiding water accumulation and increasing the vehicle load, thereby effectively reducing the vehicle energy consumption and facilitating transportation. On sunny days, the wind resistance coefficient of the vehicle can be reduced by lowering the lifting height, thereby reducing the wind resistance encountered by the vehicle during driving, thereby improving the fuel economy and driving efficiency of the vehicle, which can reduce transportation costs and help increase the income of truck drivers.
[0047] In this embodiment, see Figure 1 and Figure 2 The folding rod comprises a first folding rod 3 and a second folding rod 4, and the proximal ends of the first folding rod 3 and the second folding rod 4 are connected by a hinge 5, see Figure 3 and Figure 4 The base 2 is a channel steel, the opening of the channel steel is set upward, and the first slide groove 6 and the second slide groove 7 are respectively opened on both sides of the channel steel. The ends of the first folding rod 3 and the second folding rod 4 are respectively provided with a first slider 8 and a second slider 9, and the first slider 8 and the second slider 9 are respectively slidably set in the first slide groove 6 and the second slide groove 7.
[0048] Specifically, by arranging the first sliding block 8, the second sliding block 9, the first sliding groove 6 and the second sliding groove 7, the sliding of the folding rod is smoother, the operation is simple, and the structure is simple, thereby reducing the cost and difficulty of maintenance and repair.
[0049] In this embodiment, see Figure 1 and Figure 5 A fixed end 10 and a winding end 11 are respectively provided below the two ends of the folding rod. The tilt adjustment assembly includes a first self-locking reel 12 and a first rope body 13. The first self-locking reel 12 is installed on the frame on the same side as the fixed end 10. One end of the first rope body 13 is fixedly connected to one end of the folding rod through the fixed end 10, and the other end is slidably connected to the other end of the folding rod through the winding end 11 and turns, and is connected to the first self-locking reel 12 on the same side of the fixed end 10 after turning.
[0050] Specifically, through the arrangement of the fixed end 10, the winding end 11 and the inclination adjustment assembly, on rainy days, the truck driver only needs to reel in the first rope body 13 by rotating the first self-locking reel 12. The first rope body 13 respectively gives an inward force to the fixed end 10 and the winding end 11 of the folding rod, so that both ends of the folding rod slide inward, thereby easily increasing the lifting height of the folding rod. After the adjustment is completed, the first self-locking reel 12 can lock the position of the first rope body 13, thereby locking the lifting height of the folding rod, which is convenient for drainage on rainy days, while the operation is opposite on sunny days. The entire operation process is simple and convenient, which improves the efficiency of use.
[0051] In this embodiment, see Figure 1 , Figure 6 and Figure 7 The lifting structure includes two columns 14 and a lifting adjustment mechanism. The two columns 14 are respectively connected to the bottom of both sides of the base 2. The lifting adjustment mechanism includes a pulley 15, a second self-locking reel 16 and a second rope body 17. Lifting adjustment holes 18 are provided on both sides of the middle of the column 14. Pulleys 15 are provided in the columns 14 and the two ends of the pulleys 15 extend from the lifting adjustment holes 18 on both sides of the columns 14 respectively. The pulleys 15 are fixedly connected to the frame. The second self-locking reel 16 is connected to the frame below the columns 14. The bottom of the columns 14 is connected to the second rope body 17. The other end of the second rope body 17 is wound around the pulley 15 and connected to the second self-locking reel 16 below the column 14.
[0052] Specifically, the pulley 15, the second self-locking reel 16 and the second rope 17 are used as components of the lifting and adjusting mechanism. Combined with the design of the lifting and adjusting hole 18 in the middle of the column 14, the design of the pulley 15 can effectively change the transmission direction of the second rope 17, so that when the second self-locking reel 16 is used to reel up the second rope 17, the second rope 17 pulls the column 14 upward, thereby increasing the height of the tarpaulin and facilitating the loading of higher cargo. After the adjustment is completed, the second self-locking reel 16 can lock the position of the second rope 17, which can ensure the stability and reliability of the lifting process and reduce possible failures and problems.
[0053] It is worth mentioning that the first self-locking reel 12 and the second self-locking reel 16 mentioned above are both prior art, which can be fully realized by those skilled in the art, so they will not be described here. The number of the first self-locking reel 12 and the second self-locking reel 16 can be designed and installed according to the operating habits of the truck driver. If only one second self-locking reel 16 is used, when it is installed on the frame on one side, the four second pull ropes located around the car body need to add multiple pulleys 15 on the frame for steering to connect to the second self-locking reel 16, so that one second self-locking reel 16 can control the lifting and lowering of the surrounding pillars 14, and the first self-locking reel 12 is the same, and the first self-locking reel 12 and the second self-locking reel 16 can also be controlled by using a motor for easy use.
[0054] In this embodiment, see Figure 1 A lowest position support rod 21 is provided in the middle of the base 2 below the folding rod, which can effectively limit the descending height of the tarpaulin and the connecting rod 1 and prevent excessive descent, thereby ensuring the safety of the goods in the car.

[0056] This embodiment is obtained by further optimizing the embodiment 1. Figure 8 Both ends of the connecting rod 1 are plugged with connecting shafts 19, and the connecting shafts 19 are respectively connected to the folding rods on the adjacent side.
[0057] Specifically, the design of connecting the connecting shafts 19 at both ends of the connecting rod 1 simplifies the assembly and disassembly process of the bracket, and the truck driver can operate it easily, saving time and energy.
[0058] Embodiment 3:
[0059] This embodiment is obtained by further optimizing the embodiment 1 or the embodiment 2. Figure 8 The connecting rod 1 includes a hollow pipe, in which a connecting steel rope 20 is arranged, and both ends of the connecting steel rope 20 are respectively connected to the connecting shaft rods 19 on both sides.
[0060] Specifically, the connecting rod 1 is designed as a hollow pipe, and a plastic water pipe can be used. It is not only low-cost and can effectively reduce the weight of the connecting rod 1, but also reduces the friction between the connecting rod 1 and the tarpaulin. A connecting steel rope 20 is provided inside the hollow pipe and is connected to the connecting shaft rods 19 on both sides, which can improve the supporting effect. It can also be suitable for trucks of different lengths by extending the length of the connecting steel rope 20 and increasing the number of hollow pipes, so that the tarpaulin can be effectively propped up and is easy to use.
