Description

Technical Field

[0001] This utility model relates to the field of vehicle ramp technology, specifically a high-low span steel vehicle ramp with adjustable function. Background Technology

[0002] A steel ramp with varying elevations is a facility primarily constructed of steel used to address vehicle passage between areas of different heights. It effectively connects areas with height differences, ensuring safe and smooth vehicle passage.

[0003] The forklift ramp platform with anti-slip function disclosed in Publication No. CN221565717U has the following advantages: By using a pull-out extension plate, the tilt angle of the loading ramp can be adjusted according to specific needs and forklift characteristics to adapt to different climbing heights and angles, expanding the applicability of the ramp and improving its flexibility. If the angle is too large, a longer or steeper ramp may be needed to meet the forklift's climbing requirements; adding an extension plate can avoid this by adjusting the angle, simplifying the ramp design. However, this type of ramp platform is only suitable for use on flat surfaces. If the ground is uneven, using this ramp platform will result in installation difficulties, poor stability, uneven stress leading to easy damage, and affecting the vehicle's travel trajectory. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable high-low span steel vehicle ramp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel ramp with adjustable height and width, comprising a ramp body and a support base;

[0006] Both ends of the support base have through slots, and the top of each through slot has a receiving cavity. Several reciprocating cylinders are installed in the top of each receiving cavity. A slider is provided at the output end of each reciprocating cylinder. A lifting plate extending through to the bottom of the support base is provided at the bottom of each slider. A rectangular hole is provided in the wall of each lifting plate. A thick clamping rod is fixedly connected to the bottom of each rectangular hole. A thin clamping rod is provided between the top of the thick clamping rod and the top of the rectangular hole. A trapezoidal support foot frame is provided at the bottom of each lifting plate. Multiple sets of L-shaped stacked plates are provided inside the through slots. A thick clamping groove is provided on one side of the wall of each stacked plate, and a thin clamping groove is provided on one side of the thick clamping groove.

[0007] Preferably, the diameter of the slider is matched with the diameter of the receiving cavity.

[0008] Preferably, a level is provided on both sides of the bottom end of the support base.

[0009] Preferably, the outer diameters of the coarse and fine clamping rods are matched with the inner diameters of the coarse and fine clamping grooves.

[0010] Preferably, handles are fixedly installed on the outer wall of each stacked plate.

[0011] Compared with existing technologies, the advantages of this invention are: by activating the reciprocating cylinder, the downward-sloping end can be quickly supported, making ramp installation simpler and eliminating the need for complex ground pretreatment; the number of stacked plates can be flexibly adjusted according to the degree of ground depression. Inserting the coarse slots of the stacked plates into the coarse clamping rods is suitable for situations with deeper ground depressions, while inserting the fine slots into the fine clamping rods is suitable for scenarios with shallower ground depressions, allowing the ramp to adapt to various degrees of ground unevenness and greatly expanding its application range.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 The present invention provides the following technical solution:

[0021] Example 1: A steel ramp with adjustable heights and depths includes a ramp body 1 and a support base 2, with a level 27 installed on both sides of the bottom end of the support base 2.

[0022] When in use, staff can observe whether the support base 2 is level by placing it on the ground and using the two levels 27 at the bottom.

[0023] Example 2: The technical solution of this example, which differs from Example 1, includes: Through slots 201 are provided at both ends of the support base 2; receiving cavities 202 are provided at the top of each through slot 201; several reciprocating cylinders 23 are installed at the top of each receiving cavity 202; sliders 22 are provided at the output ends of the reciprocating cylinders 23; lifting plates 21 extending through to the bottom of the support base 2 are provided at the bottom of each slider 22; rectangular holes 203 are provided on the walls of each lifting plate 21; thick clamping rods 24 are fixedly connected to the bottom of each rectangular hole 203; thin clamping rods 25 are provided between the top of the thick clamping rods 24 and the top of the rectangular hole 203; and trapezoidal support foot frames are provided at the bottom of each lifting plate 21. 26. Multiple sets of L-shaped stacked plates 3 are arranged inside the through slot 201. A coarse groove 301 is opened on one side of the plate wall of the stacked plate 3, and a fine groove 302 is opened on one side of the coarse groove 301. The diameter of the slider 22 matches the diameter of the receiving cavity 202. The outer diameter of the coarse clamping rod 24 and the fine clamping rod 25 matches the inner diameter of the coarse groove 301 and the fine groove 302. A handle 31 is fixedly installed on the outer wall of the stacked plate 3. The rectangular hole 203 can be used to adjust the height balance of the support 2. By matching the coarse groove 301 and the fine groove 302 on the L-shaped stacked plate 3 with the coarse clamping rod 24 and the fine groove 25 respectively, the height after adjustment can be fixed.

[0024] In use, when the ground is uneven, the multiple sets of reciprocating cylinders 23 at the downward-tilting end are activated. The reciprocating cylinders 23 slide downward along the receiving cavity 202 via the slider 22, thereby driving the lifting plate 21 downward and moving its supporting frame 26, thus supporting the downward-tilting end and providing pre-support for its support base 2. At this time, observe whether the level 27 is in a horizontal state. Then, the operator can pick up the stacked plate 3 through the handle 31, stack the multiple sets of stacked plates 3 together, and insert the coarse clamping slot 301 into the coarse clamping slot. The outer end of the rod 24 can support and limit the support frame 26, and the stepped support frame 26 is better adapted to the support feet of the support base 2. This adaptability is suitable for situations where the ground is deeply recessed. When the thin slot 302 of the stacked plate 3 is inserted into the outer end of the thin clamping rod 25, the lifting plate 21 uses the top of the thick clamping rod 24 as the support point to squeeze the stacked plate 3, thereby reducing the gap between the support frame 26 and the ground. This adaptability is suitable for situations where the ground is shallowly recessed. Furthermore, the number of stacked plates 3 can be flexibly adjusted according to different inclination conditions.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
