Description

Technical Field

[0001] This utility model relates to the field of loading ramp technology, specifically a mobile loading ramp with anti-bump function. Background Technology

[0002] A loading ramp is an auxiliary device used for vehicles to enter and exit, typically installed at the entrances and exits of garages, parking lots, or factories. Its main function is to help vehicles move up and down ramps, making vehicle entry and exit easier and safer.

[0003] According to patent authorization announcement number CN218595608U, a self-propelled vehicle loading ramp belongs to the field of loading ramp technology. It includes a mounting base, a hydraulic system, and evenly distributed locking casters. The locking casters are mounted at the bottom of the mounting base, and the hydraulic system is mounted at the top. A loading ramp plate is hinged to the top of the mounting base. Two protective walls are fixedly connected to the top of the loading ramp plate. A loading ramp plate is hinged to the right side of the loading ramp plate, and a flap is hinged to the left side. Servo motors are fixedly mounted on both the front and back of the loading ramp plate. This utility model, through the combined use of an electromagnetic plate and a magnetic plate, can change the position of the extension plate. Through the combined use of a pressure sensor, it can increase the contact area between the flap and the cargo compartment wall, preventing the flap from being pressed up by a vehicle driving on it and causing an accident. This solves the problems of instability and easy warping of cargo compartment connecting plates in previous self-propelled vehicle loading ramps.

[0004] However, the bosses of existing loading ramps do not have a limiting function when they move to the rear of the carriage that needs to be limited. The bosses slide directly into the outside carriage, and the bosses are easy to detach from the outside carriage under the push of external force, which affects the vehicle transportation operation and the use effect of the loading ramp. At the same time, loading ramps are mostly supported by support legs set at various corners at the bottom of the loading ramp. The support effect in the middle position of the loading ramp is not good, so the loading ramp is easily crushed and damaged after being squeezed for a long time. Utility Model Content

[0005] The purpose of this invention is to provide a mobile loading ramp with anti-bump function, which solves the problems of limiting and supporting the loading ramp.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile loading ramp with anti-bump function, comprising a bridge plate, a boss fixedly connected to the upper end of the bridge plate, an inclined surface provided on the bridge plate, a front baffle fixedly connected to the front side of the upper end of the bridge plate, a rear baffle fixedly connected to the rear side of the upper end of the bridge plate, the front baffle and the rear baffle being the same size, multiple support legs fixedly connected to the front and rear sides of the lower end of the bridge plate respectively, wheels rotatably connected to the lower ends of the support legs, a limit mechanism provided at the lower end of the boss, and multiple support mechanisms provided at the lower end of the bridge plate.

[0007] Preferably, the limiting mechanism includes a lifting rod, a lifting rod is fixedly connected to one side of the lower end of the boss, a connecting block is fixedly connected to one side of the lifting rod, and a lifting plate is fixedly connected to the right side of the connecting block.

[0008] Preferably, a top plate is fixedly connected to the lower left side of the suspended platform, the lower end of the suspension rod is fixedly connected to the upper left side of the top plate, and a base is fixedly connected to the left side of the top plate.

[0009] Preferably, a first telescopic rod is fixedly connected to the upper end of the base, an extrusion plate is fixedly connected to the upper end of the first telescopic rod, an anti-slip pad is fixedly connected to the upper end of the extrusion plate, and the first telescopic rod is disposed at the lower end of the boss.

[0010] Preferably, the support mechanism includes a hanger, a plurality of hangers are fixedly connected to the lower end of the bridge plate, a second telescopic rod is fixedly connected to the hanger, and a reinforcing block is fixedly connected to the lower end of the second telescopic rod.

[0011] Preferably, the second telescopic rod is disposed at the lower end of the bridge plate, and the reinforcing block is fixedly connected to an auxiliary block.

[0012] Preferably, the lower end of the reinforcing block is fixedly connected to a base plate, and the lower end of the auxiliary block is fixedly connected to the upper end of the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model connects the upper end of the first telescopic rod to the extrusion plate. The extrusion plate moves upward under the push of the first telescopic rod, and then the extrusion plate pushes the anti-slip pad to press tightly against the lower end of the outer carriage, thereby increasing the limiting stability between the boss and the outer carriage and avoiding the disadvantages caused by the boss separating from the outer carriage during use.

[0015] 2. This utility model connects the base plate through the second telescopic rod, which facilitates the movement of the base plate up and down. This allows the base plate to press against the ground to support the bridge plate, increasing the stability of the support, preventing the bridge plate from moving during use, reducing pressure damage to the bridge plate, and also limiting the wheels to prevent them from rotating during use.

A top plate 84 is fixedly connected to the lower left side of the hanging plate 83. The lower end of the lifting rod 81 is fixedly connected to the upper left side of the top plate 84. A base 85 is fixedly connected to the left side of the top plate 84. The first telescopic rod 86 is fixedly connected to the upper end of the base 85. A pressing plate 87 is fixedly connected to the upper end of the first telescopic rod 86. An anti-slip pad 88 is fixedly connected to the upper end of the pressing plate 87. The anti-slip pad 88 is arranged to increase the stability of the limiting point. The first telescopic rod 86 is located at the lower end of the boss 2.

[0025] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 The support mechanism 9 includes a hanger 91. Multiple hangers 91 are fixedly connected to the lower end of the bridge plate 1.

Then, the first telescopic rod 86 is activated, and the first telescopic rod 86 drives the pressing plate 87 to move upward. Then, the pressing plate 87 presses the anti-slip pad 88 upward, so that the pressing plate 87 presses upward and adheres tightly to the lower outer side of the outer carriage. By activating the second telescopic rod 92, the second telescopic rod 92 drives the bottom plate 95 to move downward. Then, the bottom plate 95 moves downward and adheres tightly to the ground. Thus, the vehicle can be moved to the carriage to be moved through the bridge plate 1 and the boss 2. The front baffle 4 and the rear baffle 5 are set to prevent the vehicle from falling to the lower end of the bridge plate 1 when moving.
