Description

Technical Field

[0001] The utility model relates to the technical field of flatbed semi-trailers, and more specifically to a flatbed self-unloading semi-trailer capable of side-turning and unloading. Background Art

[0002] A semi-trailer is a trailer with the axle placed behind the center of gravity of the vehicle and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. There are many types of semi-trailers, generally three-axle semi-trailers, including 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, low-bed semi-trailers, etc.

[0003] Different types of semi-trailers are suitable for transporting different goods. For example, the fence type is more suitable for pulling fresh goods, the box type is more suitable for pulling bulk goods and moisture-proof and valuable goods, and the flatbed is suitable for transporting some steel, wood and other building materials;

[0004] A flatbed semi-trailer is a vehicle without railings on the vehicle, with a wide range of uses, mainly used for medium and long-distance freight transportation.

[0005] After transporting wood, the existing flatbed semi-trailer needs to unload the wood. The traditional manual unloading method is time-consuming and laborious. Some flatbed semi-trailers can lift the flatbed through the designed hydraulic cylinder to make it roll over to unload. Although it is more efficient and convenient than manual unloading, a large amount of wood is easy to pour out, roll down and accumulate on the bottom of the semi-trailer during the rollover unloading process, which is easy to cause damage to the bottom of the vehicle and hinder the vehicle from leaving. In view of this, we propose a flatbed self-unloading semi-trailer with rollover unloading. Utility Model Content

[0006] The utility model aims to overcome the shortcomings of the prior art, meet the actual needs, and provide a flatbed dump semi-trailer with side-rolling unloading to solve the technical problem that the currently unloaded wood is easily accumulated under the vehicle, which may cause damage to the vehicle bottom and hinder the vehicle from being driven away.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a flatbed dump semi-trailer for side-turning unloading, comprising a semi-trailer body, a flatbed assembly and a baffle assembly, wherein the baffle assembly is arranged at the bottom of the flatbed assembly;

[0008] The semi-trailer body comprises a support frame, a plurality of hydraulic cylinders are arranged on the top surface of the support frame, and a flat plate assembly is arranged at the output end of the hydraulic cylinder;

[0009] The plate assembly comprises a bottom plate hinged to the output end of the hydraulic cylinder, a plurality of fixing rods are connected to the bottom surface of the bottom plate, and a first support rod and a second support rod are penetrated through the side walls of the plurality of fixing rods;

[0010] The baffle assembly comprises a plurality of baffle frames arranged at the bottom of the base plate, a plurality of rolling columns are arranged inside the baffle frames, a sliding rod is arranged on the side wall of the baffle frame, and the sliding rod is arranged on the top surface of the fixing rod.

[0011] Preferably, a square sliding groove is formed between the upper portion of the fixing rod and the bottom surface of the bottom plate, and a sliding rod is arranged in the sliding groove.

[0012] Preferably, the side wall of the bottom plate is connected with a plurality of protrusions, the top surface of the baffle frame is provided with a latch hole, and the protrusions are provided with holes matching the latch holes from top to bottom.

[0013] Preferably, a plurality of square holes are opened on the top surface of the baffle frame, and a plurality of the rolling cylinders are rotatably connected to the inner side walls of the square holes. The frame thickness of the baffle frame is 2.5 cm, and the bottom circle diameter of the rolling cylinder is 4 cm.

[0014] Preferably, the baffle assembly is disposed between the two fixed rods, the baffle assembly is slidably connected to the fixed rods via the sliding rod, and the support rod 1 and the support rod 2 are disposed at the bottom of the baffle assembly.

[0015] Preferably, a plurality of convex strips are provided on the top surface of the bottom plate, and the top surface of the convex strips is a semicircular curved surface.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model pushes the flat plate assembly upward through the output end of the hydraulic cylinder, so that one side of the flat plate assembly gradually rises to form a certain tilt angle. The wood on the top surface of the flat plate assembly begins to slide to the lower side under the action of gravity, and the baffle assembly is pulled out from the bottom of the bottom plate. The slide rod is used to rotate on the two sets of fixed rods to make the baffle assembly perpendicular to the side of the semi-trailer body, and the bottom of the semi-trailer body is shielded and enclosed, so that the unloaded wood is difficult to roll down to the bottom of the semi-trailer, thereby solving the problem that a large amount of wood pouring out is easy to accumulate under the vehicle, which may cause damage to the vehicle bottom.

[0018] 2. The utility model also makes the rolling surface of the rolling column higher than the side of the baffle frame, which is conducive to the rolling column to first contact more wood and roll it, so that the wood slides to one side of the baffle assembly and is difficult to accumulate at the bottom of the semi-trailer. After unloading is completed, when the semi-trailer is driven away, the accumulated wood is moved away from the semi-trailer by the rolling action of the rolling column and will not slide under the vehicle, further solving the problem that after unloading, the bottom of the semi-trailer is prone to accumulate wood and affect the vehicle's driving away.

[0029] like Figures 1 to 7 As shown, the utility model relates to a side-rolling unloading flatbed semi-trailer, comprising a semi-trailer body 1, a flatbed assembly 2 and a baffle assembly 3, wherein the baffle assembly 3 is arranged at the bottom of the flatbed assembly 2;

[0030] The semi-trailer body 1 includes a support frame 101, six hydraulic cylinders 102 are arranged on the top surface of the support frame 101, and a flat plate assembly 2 is arranged at the output end of the hydraulic cylinder 102;

[0031] In the embodiment of the utility model, the power source is generated by the operation of six hydraulic cylinders 102, and the output ends of the six hydraulic cylinders 102 push the flat plate assembly 2 upward, so that one side of the flat plate assembly 2 gradually rises to form a certain tilt angle, and the wood on the top surface of the flat plate assembly 2 begins to slide to the lower side under the action of gravity. When most of the wood is unloaded, the hydraulic rods of the six hydraulic cylinders 102 move downward to slowly lower the flat plate assembly 2 to complete the unloading operation;

[0032] The plate assembly 2 includes a bottom plate 201 hinged to the output end of the hydraulic cylinder 102, and twelve fixing rods 203 are connected to the bottom surface of the bottom plate 201. Every six fixing rods 203 are distributed on one side of the bottom surface of the bottom plate 201, and every two fixing rods 203 form a group. The side walls of every six fixing rods 203 are penetrated by a support rod 1 204 and a support rod 2 205, and the baffle assembly 3 arranged between every two fixing rods 203 is supported by the support rod 1 204 and the support rod 2 205;

[0033] The baffle assembly 3 includes a plurality of baffle frames 301 disposed at the bottom of the bottom plate 201, a plurality of rolling columns 304 are disposed inside the baffle frames 301, a sliding rod 302 is disposed on the side wall of the baffle frames 301, and the sliding rod 302 is disposed on the top surface of the fixed rod 203;

[0034] In the embodiment of the utility model, the baffle assembly 3 is pulled out from the bottom of the base plate 201 and rotated on the two sets of fixed rods 203 through the sliding rod 302, so that the baffle assembly 3 is perpendicular to the side of the semi-trailer body 1, and the bottom of the semi-trailer body 1 is shielded and enclosed to prevent a large amount of wood from pouring out and rolling down to the bottom of the semi-trailer body 1, which may cause damage to the bottom of the vehicle and make it difficult to drive away the semi-trailer after unloading is completed.

[0035] Specifically, a square sliding groove is formed between the top of the fixing rod 203 and the bottom surface of the bottom plate 201 , and a sliding rod 302 is arranged in the sliding groove. The sliding rod 302 moves in the sliding groove, so that the baffle assembly 3 can be conveniently pulled out from the bottom of the bottom plate 201 .

[0036] Furthermore, a plurality of protrusions 202 are connected to the side wall of the base plate 201, a pin hole 303 is provided on the top surface of the baffle frame 301, and holes matching the pin hole 303 are provided on the protrusions 202 from top to bottom. By pushing the baffle assembly 3 into the bottom of the base plate 201, the pin hole 303 of the baffle assembly 3 is further aligned with the hole of the protrusion 202, and bolts are passed through the pin hole 303 and the hole, and fixed with nuts, the baffle assembly 3 is more firmly installed on the bottom surface of the base plate 201.

[0037] It is worth mentioning that two square holes are provided on the top surface of the baffle frame 301, and a plurality of rolling columns 304 are rotatably connected to the inner side walls of the square holes. The frame thickness of the baffle frame 301 is 2.5 cm, and the bottom circle diameter of the rolling column 304 is 4 cm. The rolling surface of the rolling column 304 is higher than the side surface of the baffle frame 301, which is beneficial for the rolling column 304 to first contact more wood and roll it, so that the wood slides to one side of the baffle assembly 3 and is difficult to accumulate at the bottom of the semi-trailer.

[0038] It is worth noting that the baffle assembly 3 is arranged between the two fixed rods 203, and the baffle assembly 3 is slidably connected to the fixed rod 203 through the sliding rod 302. The bottom of the baffle assembly 3 is provided with a support rod 1 204 and a support rod 2 205. By pushing the baffle assembly 3 into the bottom of the base plate 201, it is supported by the support column 1 204 and the support column 2 205, so that the baffle assembly 3 can be installed more stably at the bottom of the base plate 201.

[0039] It is worth mentioning that a plurality of convex strips 206 are arranged on the top surface of the bottom plate 201. The top surface of the convex strips 206 is a semicircular curved surface. The convex strips 206 are made of rubber material, which is beneficial to enhance the friction of the top surface of the bottom plate 201, so that the bottom is more stable when transporting wood and is not prone to sliding.

[0040] Working principle: This embodiment provides a flatbed dump trailer for side-overturning unloading. When in use, the baffle assembly 3 is pulled out from the bottom of the bottom plate 201 and rotated on the two sets of fixed rods 203 through the slide rod 302, so that the baffle assembly 3 is perpendicular to the side of the semi-trailer body 1, and the bottom of the semi-trailer body 1 is shielded and enclosed to prevent a large amount of wood from rolling down to the bottom of the semi-trailer body 1 when pouring out. Furthermore, the six hydraulic cylinders 102 work to generate a power source, and the output ends of the six hydraulic cylinders 102 push the flatbed assembly 2 upward, so that one side of the flatbed assembly 2 gradually rises, forming a certain tilt. At an inclined angle, during the process, the baffle assembly 3 is affected by its own gravity and always maintains an angle perpendicular to the bottom surface. The wood on the top surface of the flat plate assembly 2 begins to slide to the lower side under the action of gravity. When most of the wood is unloaded, the hydraulic rods of the six hydraulic cylinders 102 move downward to slowly lower the flat plate assembly 2 to complete the unloading operation and further drive the semi-trailer away. The wood that is piled up on one side of the baffle assembly 3 is affected by the multiple rolling columns 304 on the baffle assembly 3 and cooperates with the movement of the semi-trailer to make the wood slide to the ground, and the piled wood will not affect the departure of the semi-trailer.

[0041] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
