Description

Technical Field

[0001] This utility model relates to a fiberglass work platform and an aerial work vehicle, belonging to the technical field of aerial work vehicle equipment. Background Technology

[0002] Existing aerial work platforms equipped with fiberglass work platforms generally employ a structure where the connection and fixation are made at the side uprights. However, this connection method has significant drawbacks, specifically: 1. Connecting to the work platform's bracket at the side uprights restricts the platform's rotation, preventing large-angle, flexible turns and thus affecting the working range and efficiency. 2. Because the connection point is located on the side, the fiberglass work platform is prone to shifting or swaying under load, resulting in poor stability and potential safety hazards. 3. The side upright connection method requires an additional transition device at the front end of the boom, which not only increases structural complexity but also increases the overall length of the aerial work platform, negatively impacting its compactness and maneuverability.

[0003] Secondly, some existing FRP (fiberglass reinforced plastic) work platforms, in order to ensure insulation performance, have not adequately considered drainage requirements in their design, resulting in severe water accumulation on the platform after rain. Since the work bucket cannot automatically drain water through tilting or other means, traditional squeegees are required to remove the water, leading to significant water residue. This is not only time-consuming and labor-intensive but also increases the workload and safety risks for workers. Therefore, to address the limited rotation angle of existing FRP work platforms while simultaneously resolving the water accumulation problem, it is necessary to propose a new structure for FRP work platforms. Utility Model Content

[0004] Purpose of this utility model: The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fiberglass work platform and aerial work vehicle. The base plate completely eliminates the limitation on the rotation angle caused by lateral connections. Compared with existing fiberglass work platforms, it can expand the rotation angle, thereby increasing the working range and efficiency. The rigid connection between the base plate and the work vehicle bracket concentrates the connection points at the bottom of the platform, forming a stable support system, effectively preventing the platform from easily shifting or swaying under load.

[0005] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0006] In a first aspect, this utility model provides a fiberglass work platform, comprising:

[0007] Support components, including a base plate and a support frame connected to the base plate and extending to the side of the work platform;

[0008] The platform body is a glass box structure, the base plate is embedded in the bottom, and one side of the platform body is connected to the support frame;

[0009] The safety rope loops are in two sets, symmetrically connected to the support frame;

[0010] The drainage structure includes several drainage holes at the bottom of the platform body and sealing plugs inserted into the drainage holes;

[0011] The base plate has screw holes and is fixedly connected to the bracket of the work vehicle's slewing device by bolts.

[0012] Optionally, the base plate is composed of several steel plates spliced ​​together, and the base plate is H-shaped. Each steel plate is coated with multiple layers of glass fiber and forms an integrated structure with the platform body through resin.

[0013] Optionally, an entrance is provided on one side of the platform body, and two handrails are symmetrically connected to both sides of the entrance;

[0014] The entrance is connected to a footstool at the bottom and a doorway at the top.

[0015] Optionally, the platform body is provided with a plug-in socket on the side facing the gate, and a bolt is connected to the gate.

[0016] Optionally, the drainage holes are all located away from the bottom plate.

[0017] Optionally, the platform body is also equipped with a remote control mounting bracket for placing the remote control, and the remote control mounting bracket is located on the same side as the safety rope loop.

[0018] Optionally, the sealing plug has a protrusion facing the interior of the platform body.

[0019] Secondly, this utility model provides an aerial work platform, wherein the slewing device bracket of the aerial work platform is provided with a plurality of through holes for connecting to the fiberglass work platform described in the first aspect.

[0020] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0021] The base plate is installed at the bottom of the platform body and is connected to the bracket of the work vehicle through the base plate. After eliminating the side vertical ribs, the connection between the platform and the boom changes from lateral constraint to bottom support, completely eliminating the limitation of the rotation angle on the lateral connection. Compared with the existing fiberglass work platform, the present invention can directly rotate at a large angle with the rotation device without worrying about the rotation limit problem of the connection point.

[0022] This design directly installs the base plate to the bottom of the platform body, replacing the traditional side rib connection structure. Through the rigid connection between the base plate and the work vehicle bracket, the connection points are concentrated at the bottom of the platform, forming a stable support system.

[0023] The base plate uses an H-shaped steel plate as the main load-bearing component. The load is distributed through its I-shaped cross-section. The flanges of the H-shaped steel plate are bolted to the platform body and brackets to form a grid-like force system, ensuring that the load is evenly transmitted within the plane of the base plate.

[0028] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example

[0029] This embodiment provides a fiberglass work platform, such as Figure 1 The system includes: a support assembly, a platform body 1, a safety rope loop, and a drainage structure. The support assembly includes a base plate and a support frame. The base plate is pre-embedded or fixedly connected to the bottom of the platform body 1, and the support frame is connected to the base plate and to the side of the work platform. The platform body 1 is a glass box structure with its bottom connected to the base plate. The platform body 1 is mainly made of glass fiber, resin, flax, etc. During the processing of the body, steel plates and bolts for the base plate and support frame are pre-embedded inside, and then glass fiber and resin are applied to the steel plates to form a whole.

[0030] The platform body 1 is connected to the support frame at the middle of one side; the safety rope loops are in two sets, symmetrically connected to the support frame; the drainage structure includes several drainage holes 9 and sealing plugs; the drainage holes 9 are located at the bottom of the platform body 1, and the sealing plugs are inserted into the drainage holes 9; the bottom plate has screw holes, which are fixedly connected to the bracket of the work vehicle's slewing device by bolts 5. This design directly installs the bottom plate at the bottom of the platform body 1, replacing the traditional side rib connection structure, which can expand the slewing angle of the fiberglass work platform, thereby expanding the working range and increasing efficiency. Through the rigid connection between the bottom plate and the work vehicle bracket, the connection point is concentrated at the bottom of the platform, forming a stable support system, which can effectively avoid the problem of the platform easily shifting or shaking when bearing load. In addition, by directly connecting the bottom plate to the bracket, there is no need to add a transition device at the front end of the boom, simplifying the device and making the design compact.

[0031] Optionally, the base plate is composed of several steel plates 8 spliced ​​together, and the base plate is H-shaped. Each steel plate 8 is coated with multiple layers of glass fiber and integrated with the platform body 1 through resin to form an integral structure. This achieves high bending, shear, and compressive strength with relatively less material usage. The connection between the steel plates 8 and the fiberglass platform requires multiple coats of glass fiber and resin to form a unified structure before processing to create a complete fiberglass work platform, preventing delamination between the steel plates 8 and the platform body 1. In this embodiment, the steel plates 8 are pre-embedded in the glass of the platform body 1. The two ends of the main steel plate 8 are close to the two ends of the bottom surface of the platform body 1 along its length. The remaining steel plates 8 connected to the main steel plate 8 are arranged along the two ends of the bottom surface of the platform body 1 along its width. Thus, the H-shaped base plate forms a grid-like load-bearing structure for the platform body 1. The main steel plate 8 and multiple steel plates 8 work together under load to share the load, making the structural stress more reasonable. In this embodiment, reinforcing ribs connect adjacent steel plates 8 to evenly distribute the load and improve structural rigidity.

[0032] Optionally, an entrance is provided on one side of the platform body 1, and two handrails 4 are symmetrically connected to both sides of the entrance; a footrest 3 is connected below the entrance, and a gate 2 is connected above it. In this embodiment, the entrance is located on a narrower side without safety rope loops, which avoids occupying the core working area and ensures that there are no critical devices such as safety rope loops on this side, reducing functional conflicts. The two handrails 4 are symmetrically installed on both sides of the entrance by transparent bolts 10, and a footrest 3 is correspondingly provided at the bottom of the entrance, which meets the gripping needs of human climbing. At the same time, the footrest 3 is provided with anti-slip patterns to improve the safety of operation.

[0033] Optionally, the platform body 1 is provided with a plug-in seat on the side facing the gate 2. One end of the gate 2 is rotatably connected to the platform body 1, and the other end is connected to a pin 21. Through the cooperation of the pin 21 and the plug-in seat, the gate 2 can be used to close and open the entrance. When the pin 21 and the plug-in seat are plugged in, the entrance is blocked by the gate 2, which can protect personnel. When the pin 21 and the plug-in seat are not connected, the gate 2 hangs down due to gravity, and there is no obstruction to the entrance, which facilitates personnel to enter and exit.

[0034] Optionally, the drainage holes 9 are all located away from the bottom plate. In this embodiment, the accumulated water can be quickly drained and directed away from the bottom plate to prevent water from flowing through the bottom plate to the work vehicle bracket.

[0035] Optionally, the platform body 1 is also equipped with a remote control mounting bracket 7 for placing the remote control. The remote control mounting bracket 7 is located on the same side as the safety rope loop. This embodiment considers the remote control as a core control device, requiring operators to be able to quickly access and safely place it. Positioning the remote control mounting bracket 7 on the same side as the safety rope loop allows operators to easily access and place the remote control while securing the safety rope, reducing the range of motion and significantly improving operational efficiency and safety during high-altitude operations.

[0036] Optionally, the sealing plug has a protrusion facing the inside of the platform body 1, providing a point of force for the operator, so that the operator can directly pull up the protrusion and remove the sealing plug without the aid of tools.

[0037] Optionally, bolts can also be pre-embedded on the side of the main body of the fiberglass work platform to install lighting fixtures and various sensors, thereby increasing the functionality of the fiberglass work platform.

[0038] Working principle:

[0039] The bottom of the fiberglass work platform is connected to the bracket of the aerial work vehicle's slewing device via a base plate. After the base plate and the bracket are fixed with bolts 5, the fiberglass work platform can rotate at a large angle with the bracket.

[0040] The operator holds the handrail 4 and steps on the foot pedal 3 to enter the entrance. After entering the entrance, the operator fixes the entrance to the socket through the latch 21 and closes the entrance through the door 2.

[0041] After entering the entrance, the operator grabs the safety rope on the safety rope fixing ring 6 and secures it to the straps on his body. At the same time, without turning around or moving significantly, he can get the remote control through the remote control mounting bracket 7 to start working at height.

[0042] When water accumulates on the fiberglass work platform, the operator can simply pull out the sealing plug to allow the water to flow out, effectively preventing water from corroding or damaging the platform structure, while also improving the platform's anti-slip performance and operational safety. Example

[0043] This embodiment provides an aerial work platform vehicle. The slewing device bracket of the aerial work platform vehicle is provided with several screw holes for connecting with the fiberglass work platform in Embodiment 1. The working principle of the fiberglass work platform is the same as that of Embodiment 1.

[0044] In this embodiment, the slewing device bracket is bolted to the base plate of the fiberglass work platform, and after connection, it supports the fiberglass work platform. When the slewing device rotates, it can drive the fiberglass work platform to rotate without angle restriction, replacing the traditional side rib connection structure. This can expand the rotation angle of the fiberglass work platform, thereby expanding the working range and increasing efficiency.

[0045] In summary, this utility model's base plate is installed at the bottom of the platform body and connected to the work vehicle's bracket via the base plate. By eliminating the side ribs, the connection between the platform and the boom changes from lateral constraint to bottom support, completely eliminating the limitation of the rotation angle imposed by lateral connections. Compared to existing fiberglass work platforms, this invention can directly rotate 360° with the rotation device without worrying about rotation limit issues at the connection points. This design directly installs the base plate at the bottom of the platform body, replacing the traditional side rib connection structure. The rigid connection between the base plate and the work vehicle bracket concentrates the connection points at the bottom of the platform, forming a stable support system. The base plate uses an H-shaped steel plate as the main load-bearing component, distributing the load through its I-shaped cross-section. The flanges of the H-shaped steel plate are bolted to the platform body and the bracket, forming a grid-like force system that ensures the load is evenly transmitted within the plane of the base plate.
