Description

Technical Field

[0001] This application relates to the field of special operation vehicle technology, and in particular to an insulated boom for an aerial work platform. Background Technology

[0002] Aerial work platforms are vehicles that are 3 meters or taller, equipped with hydraulic or electric systems that control multiple hydraulic cylinders, and capable of lifting and lowering to perform work. Construction workers can use aerial work platforms to work in the air. They are widely used in high-altitude work fields such as power, street lighting, municipal works, landscaping, communications, airports, shipbuilding (repair), transportation, advertising, and photography.

[0003] For example, Chinese patent application number CN202310796614.4 discloses an aerial work platform, including a vehicle body, a slewing center support, a turntable, and a boom. The slewing center support is mounted on the vehicle body and its position is adjustable in the front-rear direction of the vehicle body. The turntable is mounted on the slewing center support and can rotate relative to the slewing center support. The boom is mounted on the turntable.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0005] The boom of a common aerial work platform is made of high-strength steel pipe, which has certain electrical conductivity. When working with electricity at height, it may encounter high-voltage arcing, which may cause current to be conducted through the boom to the vehicle body. This is not conducive to ensuring the personal safety of the workers or drivers on the vehicle body, and the safety needs to be improved. Utility Model Content

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] This application discloses an insulated boom for an aerial work platform. (See also...) Figure 1-4The insulated boom of the aerial work platform includes an insulated fiberglass pipe 1 and two high-strength steel pipes 2. The two ends of the insulated fiberglass pipe 1 are inserted into the two high-strength steel pipes 2 and are connected and fixed by multiple sets of tie rod assemblies 3. There is a gap between the two high-strength steel pipes 2, and part of the insulated fiberglass pipe 1 protrudes from the gap. The outer peripheral wall of the end of the insulated fiberglass pipe 1 is attached to the inner peripheral wall of the high-strength steel pipe 2. Plastic support frames 4 are also installed inside both ends of the insulated fiberglass pipe 1. The plastic support frames 4 are fixed by multiple sets of tie rod assemblies 3.

[0036] Specifically, to avoid the gap being too wide and affecting the structural strength of the insulating arm, and to avoid the gap being too narrow and affecting the insulation effect of the insulating arm, the width of the gap is between 30 and 50 centimeters. To ensure a firm connection between the insulating fiberglass pipe 1 and the two high-strength steel pipes 2, the length of the connecting part of the insulating fiberglass pipe 1 extending into the high-strength steel pipe 2 is between 50 and 120 centimeters.

[0037] Two spaced positioning plates 11 are also provided on the outer peripheral wall of the insulating fiberglass pipe 1. The positioning plates 11 are integrally formed with the insulating fiberglass pipe 1 and are perpendicular to the fixed surface of the insulating fiberglass pipe 1. The two positioning plates 11 respectively abut against the end faces of the two high-strength steel pipes 2. The vertical distance between the two positioning plates 11 is the width of the gap mentioned above.

[0038] In this embodiment, the connecting part corresponds to 4-10 sets of tie rod assemblies 3. The multiple sets of tie rod assemblies 3 are arranged along the length direction of the insulating fiberglass pipe 1. The multiple sets of tie rod assemblies 3 are arranged in two rows and multiple columns. One row of tie rod assemblies 3 is close to the top of the insulating fiberglass pipe 1, and the other row of tie rod assemblies 3 is close to the bottom of the insulating fiberglass pipe 1.

[0039] Furthermore, the tie rod assembly 3 includes a locking rod 31 and two nuts 32. Both ends of the locking rod 31 are provided with threaded sections, and the two nuts 32 are respectively threaded onto the two threaded sections. The high-strength steel pipe 2 is clamped and fixed between the two nuts 32. The tie rod assembly 3 designed above has a simple structure and is easy to assemble and disassemble.

[0040] In this embodiment, the plastic support frame 4 includes a top plate 41, a bottom plate 42, and multiple vertically arranged support plates 43. The top plate 41 and the bottom plate 42 are arranged horizontally relative to the insulating fiberglass pipe 1. The two ends of the top plate 41 abut against the two opposing inner sidewalls of the insulating fiberglass pipe 1. The top plate 41 also has multiple first through holes 411 through which the tie rod assembly 3 passes. The two ends of the bottom plate 42 abut against the two inner sidewalls of the insulating fiberglass pipe 1. The bottom plate 42 also has multiple second through holes 421 through which the tie rod assembly 3 passes. The support plates 43 vertically penetrate the middle of the top plate 41 and the bottom plate 42. The support plates 43 also have third through holes through which the tie rod assembly 3 passes. The two ends of the support plates 43 abut against the inner top wall and the inner bottom wall of the insulating fiberglass pipe 1, respectively.

[0041] The top plate 41 is provided with a plurality of first weight-reducing holes 412, which are oval in shape and located between adjacent support plates 43. The bottom plate 42 is provided with a plurality of second weight-reducing holes 422, which are oval in shape and located between adjacent support plates 43. The support plates 43 are provided with a plurality of third weight-reducing holes 431, which are arranged vertically at intervals and are circular.

[0042] The plastic support frame 4 designed above has a simple structure and high structural strength, which provides better support and reinforcement for the insulated fiberglass pipe 1. Moreover, it is relatively lightweight, making it convenient to run pipes and lines inside the insulated arm.

[0043] To prevent rainwater from adhering to the outer surface of the insulated fiberglass pipe 1 during rainy weather operations, a hydrophobic coating is provided on the outer surface of the insulated fiberglass pipe 1. The absence of rainwater adhering to the insulated fiberglass pipe 1 will significantly improve the insulation effect of the insulated arm, making rainy weather operations safer.

[0044] The beneficial technical effects of the insulated boom of the aerial work vehicle in this application embodiment are roughly as follows:

[0045] The insulated fiberglass pipe 1 has excellent insulation properties, and the gap between the two high-strength steel pipes 2 prevents current from flowing between them, which helps ensure the safety of personnel working or driving on the vehicle, resulting in higher safety. The insulated fiberglass pipe 1 itself has good structural strength and mechanical properties, and is further supported and reinforced by the internal plastic support frame 4. It is also firmly connected to the high-strength steel pipe 2 by multiple sets of tie rod assemblies 3, thereby ensuring that the insulated arm has good pressure resistance and is not easily bent or damaged when lifted to high altitudes, further ensuring safety and extending service life.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
