Description

Technical Field

[0001] The utility model relates to the technical field of escalator devices, in particular to an escalator device for getting on an excavator. Background Art

[0002] Excavators are essential machines in the construction process. They are used to use buckets to dig materials above or below the bearing surface and load them into transport vehicles or transport them to designated locations. At present, excavators are required to adapt to more and more working conditions. In order to meet the needs of various working conditions, the excavator cab needs to be raised. When the cab is raised, how the driver enters the cab from the ground becomes a problem that needs to be solved. Because the cab is raised, it is difficult to enter the cab directly from the ground, and it is usually necessary to set up an escalator to help the driver enter the cab.

[0003] Traditional escalators have small pedal depth, narrow pedals, small pedal spacing and step spacing, resulting in dense pedal distribution. Most of them are in contact with the ground at one end and the cab at the other end. It is easy to slip when getting on and off the vehicle, which poses a safety hazard. Some existing technologies, such as patent application numbers CN220580935U and CN214091680U, both disclose an escalator for excavators. The driver enters the cab by climbing the escalator, and the length of the escalator can be adjusted at the same time, which has certain applicability. However, the escalator in the above patent lacks a platform, and the driver needs to stand on the escalator pedal to open the door, which easily leads to an unstable center of gravity and poses a major safety hazard. There are also some existing technologies that are designed with platforms but still have problems. For example, patent application number CN214886801U discloses an escalator for raising the cab of an excavator, which specifically discloses a step assembly and a platform support assembly, etc. However, according to the contents recorded in its scheme and drawings, the platform in the patent is at the same height as the cab, which results in a large overall slope of the escalator, making it difficult for people to get on and off the vehicle, and inconvenient for the driver to get on and off the vehicle. The large slope of the escalator also poses risks and is not safe enough. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an escalator device for getting on an excavator. Without affecting the structural strength, the structure is optimized and improved. The height of the ladder platform is designed to be lower than the height of the base, and a foot pedal is designed on the base to achieve the purpose of reducing the overall slope, making it easier for the driver to safely enter and exit the cab.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An escalator device for getting on an excavator comprises: an escalator assembly and a base, one side of the base is close to the door of the excavator cab, and the escalator assembly is installed on the other side of the base;

[0008] As a further technical solution, the base is a rectangular parallelepiped structure, and the width of the base is adapted to the width of the excavator cab.

[0009] As a further technical solution, a foot pedal is welded on the side surface of the base facing the stair platform, and the position of the foot pedal is higher than the stair platform.

[0010] As a further technical solution, the stairs include two support beams and a plurality of pedals. The two support beams are arranged in parallel, one end of the two support beams is welded to a side surface of the stair platform, and the other end is in contact with the ground.

[0011] As a further technical solution, a plurality of pedals are welded between two support beams at equal intervals.

[0012] As a further technical solution, the pedals are all made of patterned steel plates, and anti-slip protrusions are designed on the upper surfaces.

[0013] As a further technical solution, a handrail is welded on the support beam on the side away from the base, and the handrail includes a vertical rod vertically welded on the support beam and a handrail welded to the upper end of the vertical rod.

[0014] As a further technical solution, a guardrail is fixedly connected to the upper surface of the stair platform, and the position where the guardrail contacts the handrail is connected by a fastener.

[0015] As a further technical solution, an anti-collision block is provided on the guardrail close to the handrail side.

[0016] As a further technical solution, it also includes an inclined beam, one end of which is fixedly connected to the base and faces the lower end of the stair platform, and the other end is fixedly connected to the bottom surface of the stair platform.

[0017] One or more technical solutions of the utility model have the following beneficial effects:

[0018] (1) The utility model designs the width of the step platform to be greater than the length of the excavator door, and the length of the step platform to be greater than the width of the excavator cab, so that the driver will not be affected when opening the door while standing on the step platform, and the door can be fully opened, and the driver's range of movement can be increased.

[0019] (2) The utility model designs the height of the base to be greater than the height of the step platform, adds a foot pedal to replace the step on the outside of the entrance to the cab, and welds a foot pedal on the side surface of the base facing the step platform to achieve the purpose of reducing the overall slope. This solves the problem in the prior art that the escalator has a large slope, which makes it difficult for the driver to get on and off the escalator, and also enhances the safety of the device.
