Description

Technical Field

[0001] This utility model relates to the field of widened anti-collision loading ramps, and more specifically, to a widened anti-collision loading ramp. Background Technology

[0002] Hydraulic loading ramps are specialized auxiliary equipment for rapid loading and unloading of goods. They bridge the gap between trucks and warehouse loading platforms, allowing forklifts and other handling vehicles to directly enter the trucks for bulk loading and unloading of goods. They are also called loading and unloading platforms.

[0003] In existing technology, such as the authorized announcement number CN218859885U, this utility model discloses a hydraulic loading ramp with good stability, belonging to the field of loading ramp technology. The key technical points include a base plate and a loading ramp body. The loading ramp body is installed on the top of the base plate. A fixing pipe is fixedly connected to the bottom of the loading ramp body. A hydraulic rod is installed on the fixing pipe. A support frame is fixedly connected to the bottom of the hydraulic rod. A set of moving wheels is installed on the support frame. A piston ring is fixedly connected to the middle of the hydraulic rod. The outer side of the piston ring is slidably connected to the inside of the fixing pipe. Two conduits are fixedly connected to the outer side of the fixing pipe, and one end of each conduit passes through and is fixedly connected to the inside of the base plate. This utility model can lower the overall center of gravity when the loading ramp needs to be fixed, while providing good anti-slip effect with the ground, ensuring stability, and reducing the occurrence of displacement during use.

[0004] In the aforementioned patent, the movable wheels are located at the bottom. When in use, the rollers are stuck at the bottom and cannot maintain stability. Furthermore, the flap at the front of the upper bridge is suspended in the air. When loading, the flap structure cannot support the pressure, resulting in low structural strength. In addition, the bridge uses a single hydraulic cylinder for flipping, making the structure unstable. Unloading and loading require impact resistance, and the aforementioned patent has poor impact resistance. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a widened anti-collision loading ramp, which uses a triangular bridge frame as the vehicle loading support component. It has high structural strength and high support performance. The loading platform is extended and flipped by a first hydraulic cylinder, and a second hydraulic cylinder can press down on the support side plate surface to improve the support strength of the triangular bridge frame. A support roller assembly is set on the lower surface of the loading platform. When it is flipped and retracted, the support rollers can be flipped out. There is no need to set up a separate hydraulic control system to control the extension and retraction of the rollers. In use, the rollers will not be pressed against the lower end of the support base. When placed, it is flat, providing stable support and strong impact resistance.

[0006] To solve the above problems, the present invention adopts the following technical solution.

The supporting side plate has a hinged cam fixed to its outer side surface. A second hydraulic cylinder is hinged to the hinged cam. A triangular bridge is used as the vehicle support component, which has high structural strength and high support performance. The vehicle board is extended and flipped by the first hydraulic cylinder, and the second hydraulic cylinder can press down to support the surface of the supporting side plate, improving the support strength of the triangular bridge. A support roller assembly is set on the lower surface of the vehicle board. When it is flipped and retracted, the support rollers can be flipped out. There is no need to set up a separate hydraulic control system to control the extension and retraction of the rollers. In use, the rollers will not be pressed against the lower end of the support base. When placed, it is flat, providing stable support and strong impact resistance.

[0008] Furthermore, the upper surface of the support side plate is provided with a positioning groove, and the hydraulic rod of the second hydraulic cylinder extends into the inner surface of the positioning groove.
