Description

Technical Field

[0001] This utility model relates to the field of semi-trailer box technology, specifically a side-discharge semi-trailer box. Background Technology

[0002] Side-dump semi-trailer bodies are a type of cargo box structure specifically designed for cargo transportation and loading / unloading. Their key feature is the ability to conveniently unload cargo through tipping or sliding. Most side-dump semi-trailer bodies utilize a hydraulic drive system. The hydraulic power source is typically derived from the tractor unit, using a power take-off (PTO) to drive a gear pump that generates high-pressure oil. This high-pressure oil acts on the lifting cylinders, thereby driving the body to tip or slide for unloading. While loading is required, the side door can be opened by rotating a hydraulic cylinder. However, hydraulic cylinders are prone to malfunction, and a malfunctioning side door could potentially damage cargo or people, presenting certain drawbacks. Therefore, we propose a side-dump semi-trailer body design. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a side-discharge semi-trailer body, including a body, side rails, fasteners, hydraulic cylinders, anti-collision components and support components. The side rails are rotatably connected to the front end of the body. The fasteners are arranged on the outside of the body. The hydraulic cylinders are arranged on both sides of the body. The front end of the hydraulic cylinders is rotatably connected to a connecting plate. The connecting plate is welded to the side rails. The anti-collision components are arranged on the connecting plate. The support components include a fixed seat arranged inside the side rails, a support tube rotatably connected to the fixed seat, a fastening knob threaded to the outside of the support tube, a support rod threaded to the support tube, a foot connected to the bearing at the top of the support rod, and a slot formed at the top of the foot.

[0005] Preferably, the outer side of the compartment is provided with a plurality of mounting seats, and the plurality of mounting seats are provided with round holes.

[0006] Preferably, a baffle is provided at the front end of the side rail, and a through hole is provided on the baffle.

[0010] Preferably, the anti-collision assembly includes a fixing plate screwed to the front end of the connecting plate, a spring disposed on the rear side of the fixing plate, and a buffer plate disposed on the rear side of the spring.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting a support component, this utility model can support the opened side rail without affecting the use of the carriage, avoiding the problem of the side rail hitting goods or people due to hydraulic cylinder failure, thus ensuring high safety. At the same time, the anti-collision component can provide a buffering effect and has a long service life. In use, first control the extension of the hydraulic cylinder, which will drive the side rail to rotate upward until it reaches a suitable angle. Then rotate the support tube and support rod of the support component so that the support rod is directly opposite the right angle of the edge of the carriage. Then rotate the support rod outward. During the rotation, the bottom foot can be rotated to align with the right angle of the edge of the carriage until the slot engages with the right angle of the edge of the carriage. Then tighten the fastening knob. After tightening, the support rod can be fixed inside the support tube. After fixing, the support component can support the rotated and opened side rail, avoiding the problem of the side rail hitting goods or people due to hydraulic cylinder failure, thus ensuring high safety. At the same time, the spring of the anti-collision component provides a certain buffering effect for the buffer plate, preventing the side rail from hard impacting the carriage and causing wear, thus ensuring a long service life.

[0024] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a side-discharge semi-trailer cargo box.

[0025] Example 1:

[0026] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a side-discharge semi-trailer body, including a body 100, a side rail 200, fasteners 300, a hydraulic cylinder 400, an anti-collision component 500, and a support component 600.

[0027] Specifically, the outer side of the body 100 is provided with several mounting seats 101, and the mounting seats 101 are provided with round holes. In use, the mounting seats 101 are used to install on the semi-trailer so as to install and remove the body 100.

[0028] Specifically, the side rail 200 is rotatably connected to the front end of the body 100. A baffle 201 is provided at the front end of the side rail 200, and a through hole 202 is provided on the baffle 201. In use, the side rail 200 acts as a barrier to facilitate the transport of goods, while the baffle 201 acts as a barrier to facilitate the fixation of the side rail 200 to the body 100.

[0029] Specifically, fasteners 300 are installed on the outside of the body 100. Fasteners 300 include studs 301 installed at the front end of the body 100 and nuts 302 threadedly connected to studs 301. In use, studs 301 can pass through the through hole 202 of the baffle 201. After passing through, nuts 302 can be rotated to fix the side rail 200 firmly to the body 100 for use.

[0030] Specifically, hydraulic cylinders 400 are arranged on both sides of the body 100. A connecting plate 402 is rotatably connected to the front end of the hydraulic cylinder 400. The connecting plate 402 is welded to the side rail 200. A T-shaped rod 401 is rotatably connected to the rear side of the hydraulic cylinder 400. The T-shaped rod 401 is arranged on the body 100. A rectangular hole 403 for installing the anti-collision component 500 is opened on the connecting plate 402. In use, the hydraulic cylinder 400 can rotate on the body 100 through the T-shaped rod 401, and can rotate on the side rail 200 through the connecting plate 402, so that the side rail 200 can be rotated by the hydraulic cylinder 400.

[0031] Specifically, the anti-collision component 500 is installed on the connecting plate 402. The anti-collision component 500 includes a fixing plate 501 screwed to the front end of the connecting plate 402, a spring 502 installed on the rear side of the fixing plate 501, and a buffer plate 503 installed on the rear side of the spring 502. In use, the buffer plate 503 can be inserted into the rectangular hole 403 of the connecting plate 402 and then fixed with screws. After fixing, the spring 502 makes the buffer plate 503 have a certain buffering effect, avoiding the side rail 200 from hard impacting the body 100 and causing wear, and has a long service life.

[0032] Specifically, the support assembly 600 includes a fixed base 601 disposed inside the side rail 200, a support tube 602 rotatably connected to the fixed base 601, a fastening knob 603 threadedly connected to the outside of the support tube 602, a support rod 604 threadedly connected to the support tube 602, a base 605 connected to the bearing at the top of the support rod 604, and a slot 606 formed at the top of the base 605. In use, the support tube 602 and the support rod 604 of the support assembly 600 are rotated so that the support rod 604 faces the body of the container. At the right angle of the edge of the 100, rotate the support rod 604 outward. During the rotation, the rotatable foot 605 can be aligned with the right angle of the edge of the box 100 until the slot 606 engages with the right angle of the edge of the box 100. Then tighten the fastening knob 603. After tightening, the support rod 604 can be fixed inside the support tube 602. After fixing, the rotating and opening side rail 200 can be supported by the support assembly 600, which avoids the side rail 200 from falling on goods or people due to the failure of the hydraulic cylinder 400, thus ensuring high safety.

[0033] The working principle and usage process of this utility model are as follows: First, control the hydraulic cylinder 400 to extend. The extended hydraulic cylinder 400 will drive the side rail 200 to rotate upwards until a suitable angle is reached. Then, rotate the support tube 602 and support rod 604 of the support assembly 600 so that the support rod 604 is directly opposite the right angle of the edge of the body 100. Then, rotate the support rod 604 outwards. During the rotation, the base 605 can be rotated to align with the right angle of the edge of the body 100 until the slot 606 engages with the body 100. The support rod 604 is fixed inside the support tube 602 after being tightened at the right angle of the edge 0. After being fixed, the rotating side rail 200 can be supported by the support component 600, which avoids the side rail 200 from hitting the goods or people due to the failure of the hydraulic cylinder 400. The safety is high. At the same time, the spring 502 of the anti-collision component 500 makes the buffer plate 503 have a certain buffering effect, preventing the side rail 200 from hitting the body 100 hard and causing wear. The service life is long.
