Description

Technical Field

[0001] The utility model relates to the technical field of overturning devices, in particular to a overturning device for a trailer. Background Art

[0002] A common tipping device for trailers is a device called a dump truck or unloader. This device is usually installed at the rear of the trailer and is used to dump the cargo or materials on the trailer. The working principle of the dump truck is to tip the cargo box or floor of the trailer backwards through a hydraulic system or mechanical device to discharge the cargo from the rear. The specific operation method can vary depending on the design and model, but generally speaking, the tipping device of the dump truck can be activated by a control device (such as a button, pull rod or remote control) to tip the cargo box or floor and dump the cargo. There are many different designs and models of tipping devices for dump trucks to adapt to different load capacities and usage requirements. Dump trucks are widely used in construction sites, logistics transportation and garbage removal, and can easily and quickly unload cargo or garbage from the trailer.

[0003] When a trailer uses a tipping device to dump goods, mechanical devices such as hydraulic lifting devices are used to lift and tilt the cargo box and dump all the goods. However, it is difficult for the goods to maintain a certain balance during the tipping process, and some of the upper layers of goods stacked together will tilt and fall, causing damage to the goods and clutter on the site, and even causing injuries to employees. Therefore, the present application proposes a tipping device for a trailer. Summary of the invention

[0029] Example

[0030] like Figure 1 As shown, the utility model provides a trailer tipping device, which includes a trailer 1. A plurality of roller tires are installed at the bottom of the trailer 1 to ensure the normal operation of the trailer. The trailer 1 is composed of a trailer body and a trailer head.

[0031] like Figure 1 and Figure 2 As shown, the device also includes a cargo box 2 arranged on the trailer 1, the cargo box 2 is used to transport goods, and a cargo box door 24 is hingedly connected to one side outer wall of the cargo box 2, and a handle 25 is installed on the cargo box door 24, and the cargo box door 24 is opened and closed by pulling the handle 25;

[0032] Furthermore, the cargo box 2 and the trailer 1 are connected with a hydraulic lifting device, which includes a hydraulic cylinder 6 fixedly mounted on the trailer 1, the piston rod of the hydraulic cylinder 6 is connected to the cargo box 2, an auxiliary connecting rod 7 is installed at the bottom of the cargo box 2, the auxiliary connecting rod 7 is fixedly connected to the trailer 1, and the elongation of the piston rod of the hydraulic cylinder 6 drives the cargo box 2 to be lifted and tilted, so as to facilitate dumping of the goods;

[0033] Furthermore, slide grooves 3 are fixedly installed on both sides of the cargo box 2, and sliders 4 are slidably installed in the slide grooves 3. The sliders 4 can slide back and forth in the slide grooves 3. An L-shaped connecting block 5 is fixedly installed on the top of the slider 4. A moving device is arranged in the slide groove 3, and the moving device includes a screw rod 8 rotatably installed in the slide groove 3 and threadedly connected to the slider 4. One end of the two screw rods 8 passes through the outer wall of the slide groove 3, one end of one screw rod 8 is fixedly connected to a driving wheel 9, and one end of the other screw rod 8 is fixedly connected to a driven wheel 10. The driven wheel 10 and the driving wheel 9 are connected by a belt 11. The rotation of the driving wheel 9 can drive the driven wheel 10 to rotate through the transmission of the belt 11;

[0034] It is worth mentioning that a mounting frame 13 is fixedly installed on one side of the cargo box 2, and the output shaft of the driving motor 12 fixedly installed on the mounting frame 13 is fixedly connected to the driving wheel 9. When the driving motor 12 is started, the driving wheel 9 rotates, and under the transmission action of the belt 11, the driven wheel 10 and the driving wheel 9 rotate together, and further the two screw rods 8 rotate synchronously, so that the slider 4 drives the L-shaped connecting block 5 to move forward and backward.

[0035] like Figure 2-4 As shown, the flipping device also includes a blocking and limiting device, which is connected to the L-shaped connecting block 5 to prevent the goods from unbalanced and rolling down during the overturning process. The blocking and limiting device includes a fixed block 14 fixedly connected between the two L-shaped connecting blocks 5, and an electric telescopic rod 15 is fixedly installed at the bottom of the fixed block 14. The electric telescopic rod 15 is connected to a baffle 16, and the baffle 16 is driven to drop and adjust the position by the extension of the electric telescopic rod 15, so that the baffle 16 can resist the goods stacked on the upper layer, so that the goods are fixed and limited during the tilting and overturning process, and will not all roll down and fall;

[0036] Furthermore, a protective assembly is provided on the top of the baffle 16, and the protective assembly includes a fixed column 17 fixedly installed on the top of the baffle 16, a swivel 18 is hinged on the fixed column 17, a connecting plate 19 is installed on the swivel 18, and a protective plate 20 is connected to the connecting plate 19. The swivel 18 can adjust the direction of the rotating protective plate 20, so that the protective plate 20 is adjusted according to the tilt height, which better protects the goods from falling and avoids the goods from crossing the baffle 16 due to the tilt height being too high;

[0037] Furthermore, a pushing device is provided on the baffle 16, and the pushing device includes an electric slide rail 21 arranged on one side of the baffle 16, and two moving blocks 22 are slidably installed on the electric slide rail 21, and push plates 23 are fixedly installed on the two moving blocks 22. When the goods are gradually dumped, the goods remaining in the cargo box 2 are driven by the movement of the moving blocks 22 to move the push plates 23, so that the two push plates 23 are against the two sides of the goods, and then the movement of the slider 4 is used to push out the cargo box 2 for automatic unloading.

[0038] Working principle: When the cargo box 2 is overturned and the goods are dumped, the driving motor 12 is started to rotate the driving wheel 9. Under the transmission action of the belt 11, the driving wheel 9 drives the driven wheel 10 to rotate together, and further the two screw rods 8 rotate synchronously, so that the slider 4 drives the baffle 16 to move back and forth, which can be adjusted according to the position of the goods. The extension of the electric telescopic rod 15 drives the baffle 16 to descend, which is convenient for adjustment to resist the goods stacked on the upper layer to prevent all the goods from rolling down and falling. The hinged protective plate 20 is used to rotate the rotating head 18 to adjust the direction of the protective plate 20, and then cooperate with the baffle 16 to complete the limit blocking of the goods, avoiding the situation where the goods fall and are damaged. When there are still residual goods in the cargo box 2 that have not been unloaded, the movement of the moving block 22 can be used to drive the push plate 23, and cooperate with the movement of the slider 4 to automatically unload the goods from the cargo box 2.

[0039] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
