Description

Technical Field

[0001] This application relates to the field of aerial work platform technology, and in particular to a new type of aerial work platform vehicle. 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 CN202010673599.0 discloses an aerial work platform, which consists of a carrier vehicle for supporting and installing the working mechanism and realizing the aerial work platform's mobility function, a working mechanism for realizing the lifting and folding functions of the working platform, and a hydraulic control system for realizing the lifting and folding control of the working mechanism; the working mechanism is fixed to the frame by the bottom of the support base and the seat plate, and the working basket is hinged to the rear end of the working mechanism.

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

[0005] For safety reasons, a protective fence is usually installed vertically around the rear platform of a common aerial work platform. The bottom of the protective fence is locked to the side of the rear platform with multiple bolts. In later maintenance or special working conditions, the protective fence may obstruct subsequent operations because it is much higher than the top of the platform. Therefore, workers need to remove the protective fence. During the installation and removal of the protective fence, workers need to do a lot of bolt tightening work, which is inefficient. Utility Model Content

[0006] This application provides a novel aerial work platform vehicle to address the following technical problems:

[0007] When installing or dismantling protective fences, aerial work platforms typically require workers to perform a large amount of bolt tightening work, resulting in low work efficiency.

[0008] This application provides a novel aerial work platform vehicle, which adopts the following technical solution:

[0009] A novel aerial work platform includes a rear platform and protective railings. One or more sets of protective railings are installed on both sides and the rear side of the rear platform. Each protective railing has at least two vertically arranged posts. A vertically arranged sliding mounting cylinder is fixed to the side of the rear platform, and the posts slide through the sliding mounting cylinder. An elastic element is provided inside the sliding mounting cylinder to push the posts upwards. A fixing pin is also vertically connected to the side of the rear platform. Each set of protective railings corresponds to one fixing pin. When the protective railing is pressed down below the upper surface of the rear platform, the fixing pin passes through one of the posts and locks it in place. When the protective railing rebounds above the upper surface of the rear platform, the fixing pin is pulled out and separated from the corresponding post.

[0010] In one feasible technical solution of this application, the elastic element is a spring, an abutment ring is provided on the outer peripheral wall of the middle part of the column, the column passes through the spring, and the top of the spring abuts against the lower surface of the abutment ring.

[0011] In one feasible technical solution of this application, a lower sealing ring is threadedly fitted at the bottom opening of the sliding mounting cylinder. The lower sealing ring is used to abut against the bottom of the spring, and the spring is clamped and compressed between the lower sealing ring and the abutment ring.

[0012] In one feasible technical solution of this application, an upper sealing ring is threadedly fitted at the top opening of the sliding mounting cylinder, and the upper sealing ring is used to prevent the abutment ring from disengaging from the inner cavity of the sliding mounting cylinder.

[0013] In one feasible technical solution of this application, a through hole is provided at the bottom of some or all of the columns. The through hole is used for the fixing pin to pass through vertically. The inner end of the fixing pin can be detachably inserted or threadedly connected to the side wall of the rear platform.

[0014] In one feasible technical solution of this application, the fixing pin includes a pin shaft and a ring, and the ring is fixed to the outer end of the pin shaft away from the rear platform.

[0015] In one feasible technical solution of this application, the side of the rear platform is also provided with multiple sets of fixing seats, and the fixing seats correspond one-to-one with the sliding mounting cylinder and are fixedly connected to each other.

[0016] In one feasible technical solution of this application, the fixing seat includes a T-shaped plate seat and multiple sets of fixing bolts. The two sides of the T-shaped plate seat are fixedly installed on the rear platform of the vehicle by the fixing bolts. The middle part of the T-shaped plate seat is provided with an arc groove that adapts to the outer peripheral wall of the sliding mounting cylinder. The T-shaped plate seat and the sliding mounting cylinder are welded and fixed together.

[0017] In one feasible technical solution of this application, both the protective fence and the sliding mounting cylinder are made of steel pipe, and the outer surface of the steel pipe is provided with an anti-rust coating.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] When the guardrail needs to provide protection, pull out the locking pin to separate it from the corresponding post. Driven by the elastic element, the guardrail will spring back to a position higher than the upper surface of the rear platform. In later maintenance or special working conditions, when the guardrail does not need to be higher than the upper surface of the rear platform, the guardrail can be pressed down so that the top of the guardrail is lower than the upper surface of the rear platform. Then, the guardrail can be fixed to the side of the rear platform using the locking pin.

[0020] The bottom of the protective fence in this application is no longer locked and fixed to the rear platform of the vehicle with multiple bolts. Instead, by adding a sliding mounting cylinder, elastic element and fixing pin, the protective fence is improved into a flexible structure that can slide and lift vertically. During use, it does not require workers to do a lot of bolt tightening work, and the work efficiency is higher. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a novel aerial work platform vehicle. (Refer to...) Figure 1-5 The new type of aerial work platform includes a rear platform 200 and a protective fence 100. One or more sets of protective fences 100 are installed on both sides and the rear side of the rear platform 200. Each protective fence 100 has at least two vertically arranged columns 1. A vertically arranged sliding mounting cylinder 2 is fixed to the side of the rear platform 200. The column 1 slides through the sliding mounting cylinder 2. An elastic element 3 is provided inside the sliding mounting cylinder 2. The elastic element 3 is used to push the column 1 upward. A fixing pin 4 is also vertically connected to the side of the rear platform 200. Each set of protective fences 100 corresponds to a fixing pin 4. When the protective fence 100 is pressed down to a position lower than the upper surface of the rear platform 200, the fixing pin 4 passes through one of the columns 1 and locks it in place. When the protective fence 100 rebounds to a position higher than the upper surface of the rear platform 200, the fixing pin 4 is pulled out and separated from the corresponding column 1.

[0040] Both the protective fence 100 and the sliding installation cylinder 2 are made of steel pipes, and the outer surface of the steel pipes is coated with an anti-rust coating.

[0041] To facilitate the installation of the elastic element 3 and prevent easy separation between the column 1 and the sliding mounting cylinder 2, the elastic element 3 is a spring. An abutment ring 11 is provided on the outer peripheral wall of the middle part of the column 1. The column 1 passes through the spring, and the top of the spring abuts against the lower surface of the abutment ring 11. A lower sealing ring 21 is threaded at the bottom opening of the sliding mounting cylinder 2. The lower sealing ring 21 is used to abut against the bottom of the spring. The spring is clamped and compressed between the lower sealing ring 21 and the abutment ring 11. An upper sealing ring 22 is threaded at the top opening of the sliding mounting cylinder 2. The upper sealing ring 22 is used to prevent the abutment ring 11 from disengaging from the inner cavity of the sliding mounting cylinder 2.

[0042] In this embodiment, some or all of the columns 1 are provided with through holes 12 at their bottoms. The through holes 12 are used for the vertical penetration of the fixing pin 4. The inner end of the fixing pin 4 can be detachably inserted or threadedly connected to the side wall of the rear platform 200. The fixing pin 4 includes a pin 41 and a ring 42. The ring 42 is fixed to the outer end of the pin 41 away from the rear platform 200. The fixing pin 4 designed above is easy to install and remove, which is beneficial for quickly fixing or unlocking the corresponding column 1.

[0043] In this embodiment, in order to facilitate the secure installation of the sliding mounting cylinder 2, multiple sets of fixing seats 5 are also provided on the side of the rear platform 200. The fixing seats 5 correspond one-to-one with the sliding mounting cylinder 2 and are fixedly connected to each other. The fixing seat 5 includes a T-shaped plate seat 51 and multiple sets of fixing bolts 52. The two sides of the T-shaped plate seat 51 are fixedly installed on the rear platform 200 by fixing bolts 52. The middle part of the T-shaped plate seat 51 is provided with an arc groove that adapts to the outer peripheral wall of the sliding mounting cylinder 2. The T-shaped plate seat 51 and the sliding mounting cylinder 2 are welded and fixed together.

[0044] The beneficial technical effects of the novel aerial work platform vehicle according to the embodiments of this application are roughly as follows:

[0045] When the protective fence 100 needs to play a protective role, pull out the fixing pin 4 to separate it from the corresponding post 1. Under the drive of the elastic element 3, the protective fence 100 will spring back to a position higher than the upper surface of the rear platform 200. In later maintenance or special working conditions, when it is not necessary for the protective fence 100 to be higher than the upper surface of the rear platform 200, the protective fence 100 can be pressed down so that the top of the protective fence 100 is lower than the upper surface of the rear platform 200. Then, the protective fence 100 can be fixed to the side of the rear platform 200 by the fixing pin 4.

[0046] The bottom of the protective fence 100 in this application is no longer locked and fixed to the rear platform 200 by multiple bolts. Instead, by adding a sliding mounting cylinder 2, an elastic element 3, and a fixing pin 4, the protective fence 100 is improved into a flexible structure that can slide and lift vertically. During use, it is not necessary for workers to do a lot of bolt tightening work, resulting in higher work efficiency.

[0047] 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.
