Description

Technical Field

[0001] This utility model relates to the technical field of slope testing platforms, specifically an adjustable slope testing platform. Background Technology

[0002] Aerial work platforms, as an important type of engineering machinery, are widely used in various fields such as construction, power, fire protection, shipbuilding and maintenance. Their main function is to perform operations in high-altitude environments, such as installation, maintenance, and cleaning. Climbing performance, as a key technical indicator of aerial work platforms, is directly related to the vehicle's ability to operate and its safety under different terrain conditions. Therefore, it is particularly important to conduct accurate and efficient testing of the climbing performance of aerial work platforms.

[0003] Currently, there are various testing platforms on the market for testing the climbing performance of aerial work platforms. Most of these platforms use hydraulic cylinders and other structures to automatically adjust the slope of the test bench to meet the needs of different vehicle models and testing requirements. Hydraulic adjustment is widely used due to its stable structure and convenient adjustment, and it can accurately control slope changes over a wide range, providing reliable support for testing the climbing performance of aerial work platforms. Although hydraulically adjustable climbing test platforms dominate the market, they still have some obvious shortcomings:

[0004] 1. Large footprint and inconvenient to move: Most of the ramp testing platforms on the market are integrated designs with a large overall structure and a large footprint. This limits the flexibility of their deployment in practical applications. At the same time, due to their large size and weight, these platforms often need to be disassembled and reassembled when the installation position needs to be changed. This process is not only time-consuming and labor-intensive, but may also damage the platform itself.

[0005] 2. High maintenance costs: Although the hydraulic adjustment system is stable and reliable, its internal structure is complex and contains many precision components, such as hydraulic pumps, hydraulic cylinders, and control valves. These components are prone to wear and leakage during long-term use, requiring regular maintenance and replacement, which increases the cost of use. In addition, the replacement of hydraulic oil and cleaning of the system are also necessary maintenance tasks, which further increases the maintenance costs.

[0006] 3. High manufacturing cost: The manufacturing cost of hydraulic adjustable slope test platforms is relatively high, mainly due to their complex hydraulic system and precision mechanical structure. The high manufacturing cost makes it difficult for some companies with limited budgets to afford, thus limiting the popularization and application of this type of platform.

[0007] 4. Technological Development Trends and Demands: With the continuous expansion of the aerial work platform market and the increasing diversification of testing needs, the technical requirements for hill climbing test platforms are also getting higher and higher. In the future, hill climbing test platforms will develop in a more flexible, convenient, economical and efficient direction. Specifically, it is necessary to develop a hill climbing test platform that is simple in structure, occupies a small area, is easy to move and disassemble, has low manufacturing cost and is easy to maintain, in order to meet the testing needs of different enterprises.

A fixed seat is fixedly connected to one end of the base frame, and a connecting seat is fixedly connected to one end of the test slope. The fixed seat and the connecting seat are detachably connected by a pin.

[0013] The transition slope and the base frame are detachably connected by a first bolt connection assembly.

[0014] Preferably, the height of the plurality of support frames gradually increases along the direction from the transition slope to away from the transition slope, and the inclination angle between the top surface of the plurality of support frames and the horizontal plane is consistent.

[0015] Preferably, the top surface of the transition slope is provided with multiple anti-slip strips along its length.

[0018] Preferably, the height of the plurality of fixed-angle support frames gradually increases along the direction from the transition slope to the direction away from the transition slope, and the inclination angle between the top surface of the plurality of fixed-angle support frames and the horizontal plane is consistent.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example: Please refer to Figures 1-2 This embodiment provides an adjustable hill-climbing test bench, including two parallel test platform modules 1. The two measurement platforms are used for the wheels on both sides of the test vehicle to climb hills. The distance between the two test platform modules 1 can be adjusted to accommodate different vehicle models.

[0029] In this embodiment, the test platform module 1 includes a slope support 11, a test slope 12 disposed on the top of the slope support 11, and a transition slope 13 disposed at one end of the slope support 11. The slope support 11 includes a base frame 111 and multiple support frames 112 fixedly connected to its top along the length direction of the base frame 111. The support frames 112 are welded and fixed to the base frame 111. The top of the support frames 112 is inclined. The height of the multiple support frames 112 gradually increases from near the transition slope 13 to away from the transition slope 13. The inclination angle between the top surface of the multiple support frames 112 and the horizontal plane is consistent. Through this structural design, after the test slope 12 is assembled with the slope support 11, the test slope 12 abuts against the top of the support frame 112, providing a fixed slope for the test slope 12 for climbing tests. By providing a transition slope 13 at the lower end of the test slope 12, the test vehicle is guided to climb smoothly onto the test slope 12.

[0030] In this embodiment, a fixed base 113 is fixedly connected to one end of the base frame 111, and the fixed base 113 is welded to the base frame 111. A connecting base 121 is fixedly connected to one end of the test slope 12, and the connecting base 121 is welded to the test slope 12. The fixed base 113 and the connecting base 121 are detachably connected by a pin 14. This structural design facilitates the quick assembly and disassembly of the test slope 12 and the base frame 111. The transition slope 13 is detachably connected to the base frame 111 by a first bolt connection assembly 15. This structural design also facilitates the quick assembly and disassembly of the transition slope 13 and the base frame 111. This allows the assembled adjustable climbing test platform to be divided into multiple units for transport, improving transport convenience and facilitating storage.

[0031] In this embodiment, multiple anti-slip strips are provided on the top surface of the transition slope 13 along the length direction. The anti-slip strips can be made of rubber to increase the friction of the measuring vehicle traveling on the transition slope 13, which helps the test vehicle to enter the test slope 12 more smoothly.

[0032] In this embodiment, a stop frame 122 is fixedly connected to the top of the end of the test slope 12 away from the transition slope 13. The stop frame 122 is welded and fixed to the test slope 12. The stop frame 122 acts as a stop to prevent the test vehicle from moving out of the range of the test slope 12.

[0033] In this embodiment, as Figure 3 and Figure 4 As shown, the slope support component 11 also includes a fixed angle support frame 16 disposed on the top of each support frame 112. The fixed angle support frame 16 is detachably connected to the support frame 112 via a second bolt connection assembly 17. The height of the multiple fixed angle support frames 16 gradually increases from the direction close to the transition slope 13 to the direction away from the transition slope 13. The inclination angle between the top surface of the multiple fixed angle support frames 16 and the horizontal plane is consistent. The fixed angle support frame 16 is used to adjust the height of the support frame 112, thereby adjusting the inclination angle of the test slope 12. The fixed angle support frame 16 is easy to disassemble and replace with the adjustable support frame 112. By replacing the corresponding fixed angle support frame 16, the slope of the test slope 12 can be adjusted, which has strong applicability.

[0034] In this embodiment, a plurality of positioning posts 161 are fixedly connected to the bottom of the fixed angle support frame 16, and a plurality of positioning sleeves 114 corresponding to the positions of the positioning posts 161 are embedded in the top of the support frame 112. The fixed angle support frame 16 and the support frame 112 are assembled by aligning the positioning posts 161 into the positioning sleeves 114. When assembling the fixed angle support frame 16 and the support frame 112, the fixed angle support frame 16 is aligned with the positioning posts 161 and inserted into the positioning sleeves 114 of the support frame 112 to initially position the fixed angle support frame 16 and the support frame 112, which facilitates the assembly of the fixed angle support frame 16. In this embodiment, there are four positioning posts 161 in a rectangular arrangement, and four positioning sleeves 114 are also in a rectangular arrangement corresponding to the positions of the positioning posts 161.

[0035] Working principle: In use, the connecting seat 121 on the test slope 12 and the fixed seat 113 on the slope support 11 are detachably connected by a pin 14. Then, the transition slope 13 and the base frame 111 are detachably connected by a first bolt connection assembly 15, completing the assembly of one test platform module 1. Following the above steps, the assembly of two test platform modules 1 is completed. According to the model of the test vehicle, the distance between the two test platform modules 1 is adjusted to a suitable distance. The test vehicle travels from the transition slope 13 to the test slope 12 for climbing tests. When it is necessary to adjust the slope of the test slope 12, the corresponding fixed angle is installed on the test slope 12. The fixed-angle support frame 16 allows the test slope 12 to be abutted against the fixed-angle support frame 16, thus enabling adjustment of the slope of the test slope 12. This makes it highly adaptable. Furthermore, the assembled adjustable slope test platform can be divided into three parts for transport: slope support 11, test slope 12, and transition slope 13, improving transport convenience and facilitating storage. The slope support 11, test slope 12, transition slope 13, and fixed-angle support frame 16 in the assembled adjustable slope test platform are easy to assemble and disassemble, and can be transported in multiple individual parts, improving transport convenience and facilitating storage. The assembled adjustable slope test platform has a simple structure, lower manufacturing cost compared to the automatically lifting hydraulic structures on the market, and is easy to maintain.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
