Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, specifically a quick-connect device for preventing the side-unloading vehicle from tipping over. Background Technology

[0002] Side-dump trucks are specialized self-unloading transport vehicles. Their core feature is that a hydraulic system drives the cargo box to tilt to the side, thereby quickly unloading bulk materials such as sand, gravel, coal, and ore, unlike traditional rear-dump trucks that unload at the rear. They are widely used in mines, construction sites, and other similar environments, adapting to narrow operating spaces, reducing road occupancy during unloading, and significantly improving the efficiency of bulk material transfer.

[0003] The existing Chinese patent announcement number CN219257147U, entitled "Side-dumping truck anti-tipping quick-connect device," explicitly states in its abstract that "this utility model belongs to the field of transport vehicle technology, specifically disclosing a side-dumping truck anti-tipping quick-connect device, including a suspension rod and a diagonal brace. The suspension rod is fixedly connected to the side wall of the support seat, and the diagonal brace is fixedly connected to the lower part of the suspension rod. The bottom end of the diagonal brace is fixedly connected to the support seat, and the top end is fixedly connected to the outer end of the suspension rod. A pin seat is fixedly connected to the end of the suspension rod, and several auxiliary support rods are fixedly connected to the underside of the tipping truck bed. A pin plate is fixedly connected to the lower end of one of the support rods. The pin seat and the pin plate are operably connected together, which is convenient for operation and realizes the fixation of the truck bed, ensuring that it does not tip over under normal use and improving its safety. The suspension rod is Y-shaped and symmetrically arranged relative to the vertical plane, forming an upper triangular support structure. The lower part is also fixedly connected to the diagonal brace, forming a lower vertical triangular support, which greatly improves the stability and structural strength of the suspension rod and makes it more load-bearing."

[0004] However, in this technology, when the truck bed is reset and supported by the support seat, the pin seat only connects to the pin plate. The staff still needs to be equipped with the corresponding pins for fixing. The pins are not directly connected to the truck bed or the support seat. Therefore, the staff need to carry and keep the pin parts separately, which poses a risk of losing or forgetting to carry the pins, affecting the efficiency of the operation. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-5 This utility model discloses a quick-connect device for preventing tipping over on a side-unloading vehicle, comprising a truck bed 1 and a support base 11. The truck bed 1 and support base 11 adopt the truck bed and support base structure described in the prior art patent CN219257147U. The truck bed 1 is made of Q345B high-strength steel, which has good impact resistance and load-bearing capacity, suitable for the transportation needs of bulk materials. The support base 11 is welded from Q235 carbon structural steel to ensure support stability. The rear connection structure of the truck bed 1 and support base 11 is the same as that in the prior art patent; only the front structure of the truck bed 1 and support base 11 is optimized to solve the problem of carrying additional pins.

[0020] A support platform 13 is welded and fixed to the front of the support base 11. The support platform 13 is made of 45# steel and has an overall rectangular structure with a length of 300mm, a width of 200mm, and a height of 150mm. A rectangular groove 14 is formed inside the support platform 13 along its length. The rectangular groove 14 has a length of 250mm, a width of 100mm, and a height of 80mm. Fixing components are symmetrically arranged on both sides of the rectangular groove 14 for quick fixing to the front of the truck bed 1.

[0021] The fixing component includes two side slides 2, which are formed inside the support platform 13 and communicate with the rectangular groove 14. The interior of the slide 2 is an inner hexagonal groove with an opening size of 30mm × 30mm and a depth of 120mm. A rod 21 is slidably mounted inside the slide 2, extending to the outside of the slide 2. The rod 21 is divided into two parts: a hexagonal part and a cylindrical part. The size of the hexagonal part matches the inner hexagonal groove of the slide 2, and it is made of 40Cr alloy structural steel with a chrome-plated surface to reduce the coefficient of sliding friction. The cylindrical part has a diameter of 20mm and a length of 80mm, and is also made of 40Cr alloy structural steel. The cylindrical part can extend to the outside of the slide 2.

[0022] A plug-in 12 is welded and fixed to the bottom front of the truck bed 1. The plug-in 12 is a rectangular block made of Q345B steel, with a socket inside that matches the cylindrical part of the plug rod 21. The socket has a diameter of 21mm and a depth of 50mm. The plug rod 21 is installed and removed in the socket of the plug-in 12. When the truck bed 1 is reset, the front of the truck bed 1 is supported by the support seat 11. At this time, the cylindrical parts of the plug rods 21 on both sides are aligned with the sockets of the plug-in 12. A spring 22 is installed on one side inside the slide 2. The spring 22 is made of 60Si2Mn spring steel and is a cylindrical helical compression spring according to the GB / T2089-2009 standard. One end of the spring 22 is welded and fixed to the inner wall of the slide 2, and the other end is welded and fixed to the end face of the hexagonal part of the plug rod 21. When the spring 22 is in its natural state, it can push the cylindrical part of the plug rod 21 out of the slide 2, providing preload for the docking of the plug rod 21 and the plug-in 12.

[0023] A connecting rod 23 is welded and fixed to one side of the hexagonal part of the insertion rod 21. The connecting rod 23 is made of 45 steel, with a diameter of 15 mm and a length of 50 mm. An L-shaped part 24 is welded and fixed to the side of the connecting rod 23 away from the insertion rod 21. The L-shaped part 24 is made of 8 mm thick Q235 steel plate and is bent into a 90° right angle structure. The L-shaped part 24 is located inside the rectangular groove 14, and a rack 31 is welded and fixed to the inner side of its horizontal section. The rack 31 is made of 45 steel, with a module of 2, a number of teeth of 20, and a precision grade of 7, which conforms to the GB / T10095.1-2008 standard. Inside the rectangular groove 14, a gear 3 is rotatably mounted on the inner side via a bearing. The bearing is a deep groove ball bearing 6204. The gear 3 is made of 40Cr alloy structural steel. Its module is the same as that of the rack 31, which is 2, and its number of teeth is 15. The gear 3 meshes with the racks 31 on both sides. When the gear 3 rotates, it can drive the L-shaped parts 24 on both sides to move synchronously in opposite directions.

[0024] A rotating component 32 is fixed in front of gear 3. The rotating component 32 is made of 45# steel and has a rectangular plate structure with a thickness of 10mm, a length of 120mm, and a width of 40mm. The rotating component 32 is located on the outer front side of the support platform 13. A rotating rod 33 is movably mounted inside a circular opening (12mm in diameter) on one side of the extended end of the rotating component 32. The rotating rod 33 is made of Q235 steel with a diameter of 12mm and a length of 100mm. The rotating rod 33 can rotate around a pin on one side of the rotating component 32 and can extend and retract axially. A bolt 34 is welded and fixed behind the rotating rod 33. The bolt 34 is made of 45# steel with a diameter of 14mm and a length of 20mm. The bolt 34 is engaged behind the rotating component 32 and limited by the circular opening to prevent the rotating rod 33 from moving. Pulling forward, a socket 4 is provided in front of the support platform 13 above the rotating part 32. The socket 4 is a round hole with a diameter of 12.2 mm and a depth of 20 mm. The plug 34 is installed and removed in the socket 4. When the rotating gear 3 makes the plug rods 21 on both sides fully enter the slide groove 2, the rotating rod 33 rotates until the plug 34 is aligned with the socket 4. Pushing the rotating rod 33 can make the plug 34 insert into the socket 4, thereby fixing the rotating part 32 and temporarily fixing the plug 34, so as to facilitate the tipping of the truck bed 1.

[0025] The working principle of this utility model is as follows: When it is necessary to fix the truck bed 1, after the truck bed 1 is reset, the insert 12 at the bottom front of its front end aligns with the insert rod 21 at the support platform 13. The spring 22 inside the slide groove 2 pushes the insert rod 21 to extend to the outside of the slide groove 2 and insert it into the insert 12, thereby fixing the front of the truck bed 1. When it is necessary to flip the truck bed 1, rotating the rotating component 32 drives the gear 3 to rotate. The gear 3 meshes with the rack 31 on the inner side of the L-shaped components 24 on both sides, causing the L-shaped components 24 on both sides to move synchronously in opposite directions. The molded part 24 pulls the insert rod 21 through the connecting rod 23 to compress the spring 22 and retract it into the slide groove 2. At this time, the plug 34 is aligned with the socket 4. The rotating rod 33 is pushed to insert the plug 34 into the socket 4 to fix the rotating part 32, thereby fixing the position of the insert rod 21. At this time, the truck bed 1 can be flipped. After the truck bed 1 is flipped and reset, the rotating rod 33 is pulled again to disengage the plug 34 from the socket 4. The spring 22 is reset and pushes the insert rod 21 to re-insert into the plug 12, completing the re-fixing of the truck bed 1.
