Description

Technical Field

[0001] This utility model belongs to the field of vehicle engineering technology, and in particular relates to a low-flatbed semi-trailer widening frame assembly. Background Technology

[0002] The low-bed semi-trailer widening frame assembly is a device used in low-bed semi-trailers, mainly to increase the width of the vehicle body to meet the needs of transporting oversized items. It consists of multiple components and can be adjusted according to actual needs. The widening frame usually includes a widening frame, support structure, connectors, etc.

[0003] Low-bed semi-trailers need to transport a variety of goods. If it is not convenient to widen the frame according to the actual size of the goods, the vehicle's carrying space may not be maximized, resulting in wasted space or unnecessary gaps. This cannot ensure a higher loading rate for each transport. Therefore, we propose a low-bed semi-trailer widening frame assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a low-flatbed semi-trailer widening frame assembly. By using a cylinder to pull a sliding plate, the sliding plate moves a driven bar via a moving block. Then, the driven bar moves two widening plates away from each other through a transmission, solving the problem of more flexible widening according to the actual size of the cargo.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a low-flatbed semi-trailer widening frame assembly, including a flatbed, a fixed baffle fixedly connected to the outer surface of the flatbed, a widening mechanism on the flatbed, and a reinforcing mechanism on the flatbed;

[0007] The widening mechanism includes a support frame fixedly connected to the bottom of the plate. Four cylinders are fixedly connected to the inner wall of the support frame. A sliding plate is fixedly connected to the side of each of the four cylinders that is close to each other. A moving block is fixedly connected to the top of the sliding plate. The plate has two sliding grooves inside that match the outer surface of the moving block. A driven bar is fixedly connected to the top of the moving block. There are two driven bars in total. Two connecting rods are rotatably connected to the side of each of the two driven bars that is far from each other. A push block is rotatably connected to the end of each of the two connecting rods that is far from the driven bar. The outer surface of the push block is slidably connected to the inner wall of the plate. A widening plate is fixedly connected to the side of the push block that is far from the connecting rod. A rotating baffle is rotatably connected to the inner wall of the widening plate. A locking assembly is provided on the rotating baffle.

[0008] Furthermore, the locking assembly includes a locking pin fixedly connected to the outer surface of the rotating baffle. The fixed baffle has a guide groove inside that matches the outer surface of the locking pin. The guide groove is arc-shaped. A bolt is threadedly connected to the inner wall of the fixed baffle. The outer surface of the bolt is rotatably connected to the inner wall of the locking pin.

[0009] Furthermore, a limiting block matching the inner wall of the slide is fixedly connected to the bottom of the push block, and two limiting posts are fixedly connected to the side of the widening plate that is close to each other, with the outer surfaces of the two limiting posts slidingly connected to the inner wall of the plate.

[0010] Furthermore, the inner wall of the connecting rod is fixedly connected to the outer surface of the driven bar via a bearing, and the inner wall of the fixed baffle is provided with a thread that matches the outer surface of the bolt.

[0011] Furthermore, the reinforcement mechanism includes a connecting frame fixedly connected to the bottom of the support frame, and two support frames are slidably connected to the inner wall of the connecting frame. The tops of the two support frames are fixedly connected to the bottom of the widening plate, and a sliding strip is fixedly connected to the side of the two support frames away from the fixed baffle. The sliding strip is provided with a fixing component.

[0012] Furthermore, the fixing component includes a driven block slidably connected to the inner wall of the sliding strip. A locking block is fixedly connected to the side of the driven block near the fixing baffle. Several locking grooves matching the outer surface of the locking block are opened inside the connecting frame. Two sliding grooves three are opened inside the connecting frame. The inner walls of the two sliding grooves three are slidably connected to the outer surface of the driven block. Two sliding grooves four are opened inside the connecting frame. Two moving blocks are slidably connected to the inner walls of the two sliding grooves four respectively. Bolts two are threadedly connected to the inner walls of the two moving blocks. The outer surface of the bolts two is rotatably connected to the inner wall of the driven block.

[0013] Furthermore, the support frame is triangular, the sliding bar is L-shaped, and the connecting frame has a second groove inside that matches the outer surface of the sliding bar.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a push block. Four cylinders pull the sliding plate away from each other. The sliding plate then moves two driven bars away from each other via a moving block. The driven bars then push the push block via a connecting rod. Finally, the push block pushes the widening plate. At this time, the widening plate also causes the limiting post to slide within the flat plate. By pushing the push block via the connecting rod, the widening can be adjusted more flexibly according to the size of the goods, maximizing the use of the vehicle's carrying space, avoiding waste or unnecessary gaps, and ensuring a higher loading rate for each transport.

[0016] 2. This utility model incorporates an expansion plate, which causes two support frames to move away from each other. Simultaneously, both support frames move sliding strips within the second slide groove, which in turn moves the driven block. This, in turn, causes the driven block to move the locking block. The driven block, via bolt two, also moves the moving block within the fourth slide groove. By using the expansion plate to move the support frames, the expansion plate provides stable support, effectively distributing the load and preventing deformation, bending, or breakage during transport, thus improving the overall stability of the expansion frame.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 As shown, this utility model is a low-flatbed semi-trailer widening frame assembly, including a flatbed 101, a fixed baffle 102 fixedly connected to the outer surface of the flatbed 101, a widening mechanism 2 provided on the flatbed 101, and a reinforcing mechanism 3 provided on the flatbed 101. This device can widen the flatbed 101 through the widening mechanism 2, and then after widening, the reinforcing mechanism 3 can provide stable support for the widening mechanism 2.

[0030] The widening mechanism 2 includes a support frame 201 fixedly connected to the bottom of the flat plate 101. Four cylinders 202 are fixedly connected to the inner wall of the support frame 201. A sliding plate 203 is fixedly connected to the side of the four cylinders 202 that are close to each other. A moving block 204 is fixedly connected to the top of the sliding plate 203. After the four cylinders 202 are started, they will pull the sliding plate 203 in a direction away from each other. Then the sliding plate 203 drives the moving block 204 to move, thereby carrying out the next transmission step.

[0031] The plate 101 has two grooves 210 inside that match the outer surface of the movable block 204. A driven bar 205 is fixedly connected to the top of the movable block 204. Two driven bars 205 are provided in total. Two connecting rods 206 are rotatably connected to the sides of the two driven bars 205 that are away from each other. The movable block 204 slides within the grooves 210, and then the movable block 204 drives the driven bars 205 to move, thereby causing the driven bars 205 to push the connecting rods 206. The two connecting rods 206, on the side away from the driven bars 205... Each end is rotatably connected to a push block 207. The outer surface of the push block 207 is slidably connected to the inner wall of the plate 101. A widening plate 208 is fixedly connected to the side of the push block 207 away from the connecting rod 206. A rotating baffle 212 is rotatably connected to the inner wall of the widening plate 208. A locking component is provided on the rotating baffle 212. The connecting rod 206 will push the push block 207, causing the push block 207 to slide inside the plate 101. Then the push block 207 pushes the two widening plates 208 in a direction away from each other, thus widening the plate 101.

[0032] The locking assembly includes a locking pin 213 fixedly connected to the outer surface of the rotating baffle 212. The fixed baffle 102 has a guide groove 214 that matches the outer surface of the locking pin 213. The guide groove 214 is arc-shaped. A bolt 215 is threadedly connected to the inner wall of the fixed baffle 102. The outer surface of the bolt 215 is rotatably connected to the inner wall of the locking pin 213. The bolt 215 can be tightened in the fixed baffle 102. At this time, the bolt 215 fixes the locking pin 213, thereby fixing the rotating baffle 212.

[0033] The bottom of the push block 207 is fixedly connected to a limiting block 211 that matches the inner wall of the slide groove 210. Two limiting posts 209 are fixedly connected to the side of the widening plate 208 that is close to it. The outer surfaces of the two limiting posts 209 are slidably connected to the inner wall of the plate 101. The limiting block 211 restricts the movement trajectory of the push block 207 to prevent the push block 207 from deviating during movement and to ensure that the device can perform normal transmission.

[0034] The inner wall of the connecting rod 206 is fixedly connected to the outer surface of the driven bar 205 through a bearing. The inner wall of the fixed baffle 102 is provided with a thread that matches the outer surface of the bolt 215. The connecting rod 206 is connected to the driven bar 205 through the bearing, which can effectively reduce the friction between the connecting rod 206 and the driven bar 205 and extend the service life of the device.

[0035] The reinforcement mechanism 3 includes a connecting frame 301 fixedly connected to the bottom of the support frame 201. Two support frames 302 are slidably connected to the inner wall of the connecting frame 301. The tops of the two support frames 302 are fixedly connected to the bottom of the widening plate 208. Sliding strips 303 are fixedly connected to the side of the two support frames 302 away from the fixed baffle 102. The sliding strips 303 are equipped with fixing components. When the widening plate 208 moves, it will drive the support frames 302 to slide within the connecting frame 301, so that the support frames 302 can always provide a certain support for the widening plate 208.

[0036] The fixing component includes a driven block 305 slidably connected to the inner wall of the sliding bar 303. A locking block 306 is fixedly connected to the side of the driven block 305 near the fixing baffle 102. The connecting frame 301 has several slots 307 that match the outer surface of the locking block 306. The connecting frame 301 has two sliding grooves 308. The locking block 306 can be locked in the slots 307 to fix the sliding bar 303. Then the sliding bar 303 fixes the support frame 302.

[0037] The inner walls of the two slide grooves 308 are slidably connected to the outer surface of the driven block 305. The connecting frame 301 has two slide grooves 309 inside. The inner walls of the two slide grooves 309 are slidably connected to two moving blocks 310. The inner walls of the two moving blocks 310 are threaded with bolts 311. The outer surface of the bolts 311 is rotatably connected to the inner wall of the driven block 305. The slide grooves 309 restrict the position of the moving blocks 310 to prevent the moving blocks 310 from rotating due to the rotation of the bolts 311, and ensure that the bolts 311 can be properly tightened in the moving blocks 310.

[0038] The support frame 302 is triangular, the sliding bar 303 is L-shaped, and the connecting frame 301 has a second sliding groove 304 that matches the outer surface of the sliding bar 303. The second sliding groove 304 limits the sliding bar 303 so that the sliding bar 303 can only move along the second sliding groove 304, preventing the sliding bar 303 from deviating during movement.

[0039] One specific application of this embodiment is:

[0040] When the staff needs to use the equipment to widen it, they need to first unscrew bolt 215 from the fixed baffle 102 and the locking post 213. Then, the rotating baffle 212 can be rotated in the widening plate 208. At this time, the rotating baffle 212 will drive the locking post 213 to rotate, so that the locking post 213 slides out from the guide groove 214, thereby disengaging the locking post 213 from the fixed baffle 102. Then, the cylinder 202 can be activated. At this time, the four cylinders 202 will pull the sliding plate 203 in a direction away from each other.

[0041] Then, the sliding plate 203 drives the two driven bars 205 to move away from each other through the moving block 204. After that, the driven bars 205 push the push block 207 through the connecting rod 206. Finally, the push block 207 pushes the widening plate 208. At this time, the widening plate 208 also drives the limiting post 209 to slide within the plate 101, so that the two widening plates 208 move away from each other, thereby widening the plate 101. This achieves more flexible widening according to the size of the goods, maximizes the use of the vehicle's carrying space, avoids waste or unnecessary gaps, and ensures a higher loading rate for each transport.

[0042] At this time, the widening plate 208 will also drive the two support frames 302 to move away from each other. At this time, the two support frames 302 will drive the sliding bar 303 to slide in the second slide groove 304. Then the sliding bar 303 will drive the driven block 305 to move, thereby causing the driven block 305 to drive the locking block 306 to move. This achieves stable support for the widening plate 208 after widening, effectively distributing the load and preventing the widening plate 208 from deforming, bending or breaking during transportation, thereby improving the stability of the entire widening frame.

[0043] At the same time, the driven block 305 will also drive the moving block 310 to slide in the slide groove 309 through the bolt 2 311. After the widening is completed, the bolt 2 311 can be tightened in the moving block 310. At this time, the bolt 2 311 will drive the driven block 305 to move towards the slot 307, so that the driven block 305 drives the slot 306 to move, and the slot 306 is locked in the slot 307 to reinforce the position of the support frame 302.
