Description

Technical Field

[0001] This utility model relates to the technical field of articulated boom aerial work platform accessories, and in particular to a boom for an articulated boom aerial work platform. Background Technology

[0002] The boom is a crucial component of an articulated boom lift, used to adjust its angle to achieve the desired height. The boom typically consists of several boom segments hinged together, with hydraulic cylinders controlling the rotation of these segments to move the work platform into position. Existing booms are usually one-piece structures; the hinged joints are prone to damage due to prolonged use, requiring replacement of the entire boom, which is costly. Utility Model Content

[0003] This utility model aims to address the shortcomings of existing technologies by providing a boom for articulated boom aerial work platforms.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A boom for an articulated boom aerial work platform includes several booms hinged together. Each boom has a connecting end plate at both ends. A first connecting seat is detachably mounted on one connecting end plate via bolts, and a second connecting seat is detachably mounted on the other connecting end plate via bolts. The first connecting seat has two ear plates, and the second connecting seat has a hinge plate. The hinge plate of one boom passes between the two ear plates of an adjacent boom and is hinged by a pin. A mounting base is provided at the bottom of the boom, and an H-shaped seat is detachably mounted on the mounting base via bolts. The lower ends of the two side plates of the H-shaped seat have hinge holes for hinged connection with hydraulic cylinders.

[0006] The mounting base has several mounting holes running through its side wall. The upper ends of the two side plates of the H-shaped base are fixed to the mounting base by bolts in one of the mounting holes.

[0007] Several reinforcing ribs are provided on the top of the boom and the outer side walls.

[0008] The top of the boom is equipped with several arc-shaped cable management rings.

[0009] The beneficial effects of this utility model are: the hinge joint between the arms is installed in a detachable manner, which means that when the hinge joint is damaged, only a part needs to be replaced, saving costs and increasing convenience. Attached Figure Description

[0013] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0015] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is described as "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is described as "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1 to 2 As shown, a boom for an articulated boom aerial work platform includes several booms 1 articulated together, as well as a connecting end plate 2, a first connecting seat 3, a second connecting seat 4, an ear plate 5, a hinge plate 6, a pin 7, a mounting base 8, an H-shaped seat 9, a hinge hole 10, a mounting hole 11, a reinforcing rib 12, and an arc-shaped cable management ring 13.

[0019] Both ends of the boom 1 are provided with connecting end plates 2. One connecting end plate 2 is detachably mounted with a first connecting seat 3 by bolts, and the other connecting end plate 2 is detachably mounted with a second connecting seat 4 by bolts. The first connecting seat 3 is provided with two ear plates 5, and the second connecting seat 4 is provided with a hinge plate 6. The hinge plate 6 of one boom 1 passes between the two ear plates 5 of the adjacent boom 1 and is hinged by a pin 7.

[0020] Several reinforcing ribs 12 are provided on the top and side walls of the boom 1 to improve the overall strength of the boom 1.

[0021] The bottom of the boom 1 is provided with a mounting base 8, and an H-shaped seat 9 is detachably mounted on the mounting base 8 by bolts. The lower ends of the two side plates of the H-shaped seat 9 are provided with hinge holes 10 for hinge connection with the oil cylinder.

[0022] The mounting base 8 has several mounting holes 11 running through its side wall. The upper ends of the two side plates of the H-shaped seat 9 are fixed to the mounting base 8 by bolts in one of the mounting holes 11.

[0023] The top of the boom 1 is equipped with several arc-shaped cable management rings 13, which can pass the relevant cables through the inside of the arc-shaped cable management rings 13, so as to avoid the cables being messy and affecting the boom adjustment angle.

[0024] The boom 1 has a hollow internal structure, which reduces weight.

[0025] The edges of the ear plate 5 and the hinge plate 6 are chamfered, and the lower ends of the two side plates of the H-shaped seat 9 are also chamfered, which can avoid the hidden dangers caused by sharp edges and corners.

[0026] The hinge joint between the arms 1 of this utility model is installed in a detachable manner, which means that if the hinge joint is damaged, only part of it needs to be replaced, saving costs and increasing convenience.

[0027] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
