[0011] The square tube has a tenon on its outer side, and the frame has a positioning sleeve on its outer side corresponding to the tenon. The tenon is inserted into the positioning sleeve.

[0012] A hydraulic cylinder is provided under the frame, the output end of the hydraulic cylinder passes through the square tube, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the side plate;

[0013] The square tube has a through hole that mates with the hydraulic cylinder.

[0014] The channel steel has support plates at both ends that are parallel to the side plate. The support plates have vertical guide rods. The inner side of the side plate has a guide sleeve that cooperates with the guide rods. The guide rods and the guide sleeves are slidably connected.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Please see Figure 1-8 This utility model provides a technical solution: a horizontal roll material transport automatic lifting and covering device, including a base frame 20 installed on a frame 10. The base frame 20 includes two parallel square tubes 22, and eleven channel steels 21 are evenly arranged between the two square tubes 22. The eleven channel steels 21 are welded sequentially between the two square tubes 22 to form the base frame 20.

[0032] The square tube 22 has a tenon 23 on its outer side, and the frame 10 has a positioning sleeve on its outer side corresponding to the tenon 23. The tenon 23 is inserted into the positioning sleeve. When the bottom frame 20 is installed on the frame 10, the tenon 23 and the positioning sleeve cooperate to make it easy to align the bottom frame 20 with the frame 10 and avoid the bottom frame 20 from shifting relative to the frame 10.

[0033] The base frame 20 has lifting frames 30 on both sides of its surface. Each lifting frame 30 includes two parallel side plates 31. A horizontal plate 32 is located at one end between the two side plates 31. A positioning gear 34 is rotatably mounted on one end of the outer side plate 31, and a drive gear 66 is rotatably mounted on the other end of the outer side plate 31. The positioning gear 34 and the drive gear 66 are connected by a drive chain 35. A track 36 parallel to the drive chain 35 is located on the outer side of the side plate 31, and twelve rollers are slidably mounted on the track 36 on the same side. The frame 52 has U-shaped awning rods 50 on the roller brackets 52 at the same position between the two side plates 31. The outside of the U-shaped awning rods 50 is covered with a rainproof awning cloth. A telescopic cross link 51 is provided between two adjacent U-shaped awning rods 50. The bottom of the roller bracket 52 at the rear is provided with a positioning plate 55. The positioning plate 55 is fixedly connected to one side of the drive chain 35 by a U-shaped clip 56. The bottom frame 20 is provided with a V-shaped frame 40 for placing aluminum coils. The cross plate 32 is provided with an awning telescopic power mechanism 60 that drives the drive chain 35.

[0034] When the rainproof tarpaulin needs to be unfolded, the tarpaulin telescopic power mechanism 60 drives the drive chain 35 to rotate clockwise around the drive gear 66 and the positioning gear 34. Simultaneously, the drive chain 66 drives the rear roller bracket 52 to move along the track 36 towards the rear of the vehicle. At the same time, the rear roller bracket 52 drives the rear U-shaped tarpaulin poles 50 to unfold towards the rear of the vehicle, and sequentially unfolds the remaining U-shaped tarpaulin poles 50, thus opening the rainproof tarpaulin. When the rainproof tarpaulin needs to be folded, the tarpaulin telescopic power mechanism 60 drives the drive chain... The 35 rotates counterclockwise around the drive gear 66 and the positioning gear 34, which can drive the rear roller bracket 52 to move along the track 3 towards the front of the vehicle, thereby driving the rear U-shaped canopy pole 50 to move towards the front of the vehicle, and then sequentially pushing the remaining U-shaped canopy poles 50 towards the front of the vehicle, folding all the U-shaped canopy poles 50 together, thereby realizing the automatic folding of the rainproof tarpaulin. It can automatically fold or unfold the rainproof tarpaulin as needed, which is convenient to use, improves the efficiency of covering the tarpaulin, and solves the safety risk of the driver slipping and falling and causing injury.

[0035] Since the aluminum coils come in different diameters, a fixed-height covering device cannot accommodate different coil diameters and gate heights. Therefore, a hydraulic cylinder 24 is installed under the frame 10. The output end of the hydraulic cylinder 24 passes through a square tube 22 and is fixedly connected to the bottom of the side plate 31. The surface of the square tube 22 has clearance holes that cooperate with the hydraulic cylinder 24. When the diameter of the loaded aluminum coil is less than 1.8 meters and the height of the factory gate is within 3.6 meters, the hydraulic cylinder 24 drives the lifting frame 30 to descend to the lowest height. At the same time, the U-shaped canopy pole 50 also descends a distance to ensure that the transport vehicle can pass through the factory gate normally. When the diameter of the loaded aluminum coil is greater than 1.8 meters and the height of the factory gate is greater than 3.6 meters, the hydraulic cylinder 24 raises the lifting frame 30, thereby raising the U-shaped canopy pole 50 to a certain height, making it easier to load the large-diameter aluminum coil onto the V-shaped frame 40, while ensuring that the height of the U-shaped canopy pole 50 is lower than the height of the factory gate.

[0036] The channel steel 21 has support plates 25 at both ends that are parallel to the side plate 31. The support plates 25 have vertical guide rods 26. The inner side of the side plate 31 has guide sleeves 33 that cooperate with the guide rods 26. The guide rods 26 and the guide sleeves 33 are slidably connected. When the lifting frame 30 is raised or lowered, the guide rods 26 and the guide sleeves 33 cooperate to guide the lifting frame 30 and prevent it from tilting during the lifting process.

[0037] The upper surface of the track 36 has a first slide rail, and the lower surface of the track 36 has a second slide rail. The bottom of the inner side of the roller bracket 52 is rotatably mounted with an upper roller 53 and a lower roller 54 from top to bottom. The upper roller 53 slides along the first slide rail, and the lower roller 54 slides along the second slide rail. The roller bracket 52 is slidably mounted on the slide rail 36 by the cooperation of the upper roller 53 and the lower roller 54, so as to prevent the roller bracket 52 from falling off the slide rail 36.

[0038] The tarpaulin telescopic power mechanism 60 includes a right-angle geared motor 61 fixedly mounted on a horizontal plate 32. The output end of the right-angle geared motor 61 is provided with a drive gear 63. A rotating shaft 62 is rotatably mounted in front of the horizontal plate 32. Both ends of the rotating shaft 62 are fixedly connected to the central shaft of the drive gear 66. A driven gear 64 is provided on one side of the surface of the rotating shaft 62. The drive gear 63 and the driven gear 64 are connected by a transmission chain 65. The right-angle geared motor 61 drives the drive gear 63 to rotate, and then the driven gear 64 is driven to rotate under the action of the transmission chain 65, thereby driving the rotating shaft 62 to rotate, and then driving the drive gears 66 at both ends of the rotating shaft 62 to rotate, so as to achieve the purpose of driving the drive chain 35 for transmission.

[0039] Working principle: When in use, the aluminum coil to be transported is placed on the V-shaped frame 40. Then, the right-angle reduction motor 61 drives the drive gear 63 to rotate. Under the action of the transmission chain 65, the driven gear 64 rotates, which in turn drives the rotating shaft 62 to rotate. Then, the drive gears 66 at both ends of the rotating shaft 62 rotate, which drives the drive chain 35 to rotate clockwise around the drive gear 66 and the positioning gear 34. At the same time, the drive chain 66 drives the tail roller bracket 52 to move along the track 36 towards the rear of the vehicle. Simultaneously, the tail roller bracket 52 drives the tail U-shaped canopy pole 50 to unfold towards the rear of the vehicle, and sequentially drives the remaining U-shaped canopy poles 50 to unfold, thereby opening the rainproof tarpaulin.

[0040] After the aluminum coils are transported to the designated location, the rainproof tarpaulin needs to be folded up before unloading. Then, the tarpaulin telescopic power mechanism 60 drives the drive chain 35 to rotate counterclockwise around the drive gear 66 and the positioning gear 34, which can drive the roller bracket 52 at the rear to move along the track 3 towards the front of the vehicle, thereby driving the U-shaped tarpaulin pole 50 at the rear to move towards the front of the vehicle, and then push the remaining U-shaped tarpaulin poles 50 towards the front of the vehicle in sequence, folding all the U-shaped tarpaulin poles 50 together, thus realizing the automatic folding of the rainproof tarpaulin.

[0041] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
