Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, and particularly relates to an aerial work telescopic platform. Background Art

[0002] Mobile lifting work platform: a device used to transport personnel, tools, and materials to a designated height working position, consisting of components such as a working platform, an extension mechanism, a chassis, an electrical control system, and a hydraulic execution system; aerial work platforms can be mainly divided into scissor types, folding boom types, straight boom types, etc. according to the form of the boom.

[0003] Working platform: The working platform is the load-bearing component of the mobile lifting work platform, and under the action of the extension structure, it transports personnel, tools, materials, etc. to the corresponding target positions.

[0004] Mobile lifting work platforms are often used in indoor decoration, basements, narrow buildings and other usage environments. Therefore, they need to frequently enter and exit passages with height restrictions such as elevators and door openings. For mobile work platforms with a relatively high overall height, only by removing the working platform can the purpose of reducing the overall height be achieved.

[0005] As Figure 1-2 shown, in a folding and adjustable working platform, the folding guardrail and the platform body are connected by a pin shaft. The guardrail can rotate along the pin shaft towards the inside of the working platform to achieve the folding of the guardrail, thereby achieving the purpose of reducing the height of the working platform and the overall height, and finally meeting the passability of the whole machine in a space with height restrictions. However, although the folding working platform can reduce the platform height and achieve the passability of the whole machine, the guardrail still has the following problems: 1. When passing through an area with height restrictions, the use function of the mobile lifting work platform can only be restored after the guardrail is readjusted in place, and the operation is complex and the convenience is poor;

[0006] 2. Due to the different heights of the operators, the height of this guardrail is fixed and cannot be adjusted, which cannot meet the comfort requirements of personnel with different heights. Content of the Utility Model

[0007] Aiming at the problems existing in the above-mentioned prior art, the utility model provides an aerial work telescopic platform, which adjusts the height of the working platform in the up and down direction to meet the passability of the whole machine; through the selection of different adjustment points, multi-stage debugging is realized, and the applicability of the whole machine is increased to solve the above problems.

[0008] To achieve the above object, the technical solution adopted by the present utility model is as follows: An aerial work telescopic platform, comprising: a platform body and a height-adjustable guardrail installed on the platform body. A plurality of the height-adjustable guardrails are installed on the platform body and are arranged around the operation area of the platform body. The height-adjustable guardrail includes: an upper guardrail, a lower guardrail, and an adjustable component. The lower end of the lower guardrail is installed on the platform body, and its upper end is connected to the upper guardrail through the adjustable component. The overall height of the height-adjustable guardrail is adjusted through the adjustable component.

[0009] Further, the adjustable component is a fixing member provided with an installation groove. The lower end of the upper guardrail is arranged in the installation groove, and a plurality of installation holes with different heights are provided on the side wall of the fixing member.

[0010] Further, the adjustable component is a fixing cylinder provided with an installation hole. The upper guardrail is inserted into the installation hole, and a plurality of installation holes with different heights are provided on the fixing cylinder.

[0011] Further, the adjustable component is connected to the upper guardrail and the lower guardrail through bolts, spring pins or pin shafts.

[0012] Further, the upper guardrail is of a C-shaped structure, and an installation through hole for fixing to the adjustable component is provided at its lower end.

[0013] Further, the lower guardrail is of an H-shaped structure, and an installation through hole for fixing to the adjustable component is provided at its upper end.

[0014] The beneficial effects of the present utility model are as follows: The guardrail is changed from being rotated and folded around a pin shaft to being telescopically adjusted in the up and down direction, reducing the overall height of the machine, increasing the passability of the machine, and realizing multi-stage adjustment. The telescopic adjustment type working platform has a simple structure form and is convenient to operate, improving the convenience of use of the whole machine. At the same time, it can be adjusted according to the different heights of operators as needed, meeting the use requirements of operators of different heights. Description of the Drawings

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0023] As Figure 3-5 shown, a telescopic platform for working at height includes: a platform body 1 and a height-adjustable guardrail installed on the platform body 1. A plurality of the height-adjustable guardrails are installed on the platform body 1 and are arranged around the operation area of the platform body 1. The height-adjustable guardrail includes: an upper guardrail 2, a lower guardrail 4, and an adjustable component 3. The lower end of the lower guardrail 4 is installed on the platform body 1, and its upper end is connected to the upper guardrail 2 through the adjustable component 3. The overall height of the height-adjustable guardrail is adjusted through the adjustable component 3.

[0024] Further in this embodiment, the adjustable component 3 is a fixing member provided with an installation groove. The lower end of the upper guardrail 2 is arranged in the installation groove, and a plurality of installation holes with different heights are provided on the side wall of the fixing member.
