[0015] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0016] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 As shown, this utility model provides a top drive front cover with integrated maintenance platform function, which is disposed on the top drive body and includes: The front cover bracket 2 is vertically fixed on the top drive body; multiple components are mounted on the front cover bracket 2. The protective cover 7 is rotatably connected to the bottom of the front cover bracket 2. When the protective cover 7 is rotated to be parallel to the front cover bracket 2, it can just cover the front cover bracket 2 so that each component is located between the protective cover 7 and the front cover bracket 2. Fastener 11 is used to securely connect the protective cover 7 and the front cover bracket 2 when they are parallel; A limiting component is provided, which is connected to the front cover bracket 2 and the protective cover 7 respectively; the limiting component is used to limit the maximum rotation of the protective cover 7 to a horizontal state, at which time the protective cover 7 can be used as a maintenance platform.

[0018] In this technical solution, all the aforementioned components are integrated and mounted on the front cover bracket 2, and then the protective cover 7 is rotatably connected to the front cover bracket 2. The front cover bracket 2 is provided with holes for mounting the aforementioned components, as shown in the figure. Figure 1 The front cover bracket 2 is equipped with hydraulic control valve assembly 10, junction box assembly 1, hydraulic oil tank 4, and other electrical and hydraulic components. When no maintenance is required, the protective cover 7 is in a vertical position and covers the front cover bracket 2, providing protection for the components. At this time, the protective cover 7 is fixed to the front cover bracket 2 by the fixing member 11, and the entire top drive front cover is in a closed state. (Refer to...) Figure 2 When maintenance is required, the fixing member 11 is released, causing the protective cover 7 to flip downwards. Under the action of the limiting component, the protective cover 7 is maintained in a horizontal state. At this time, the entire top drive front cover is in an open state, and the protective cover 7 can serve as a maintenance platform for construction personnel to stand on and centrally perform maintenance on the various components on the front cover bracket 2.

[0019] In another technical solution, the limiting component is a chain 5, one end of which is fixed to the upper end of the front cover bracket 2, and the other end is fixed to the upper end of the protective cover 7. (Refer to...) Figure 1 The two ends of the chain 5 are respectively connected and fixed to the front cover bracket 2 and the protective cover 7 via the first shackle 3 and the second shackle 6. By controlling the length of the chain 5, the downward flip angle of the protective cover 7 can be limited. When the top drive front cover is closed, the entire chain 5 is located between the front cover bracket 2 and the protective cover 7.

[0020] In another technical solution, the limiting component is a two-link structure consisting of two hinged rods. One end of the two-link structure is hinged to the upper end of the front cover bracket, and the other end is hinged to the upper end of the protective cover. By controlling the length of the two-link structure, the downward flip angle of the protective cover 7 can be limited. When the top drive front cover is closed, the two links are folded together and stored inside the protective cover 7.

[0021] In another technical solution, the fixing element 11 is a bolt, and the upper ends of both the front cover bracket 2 and the protective cover 7 are provided with threaded holes. The bolt 11 allows for quick fixing and separation of the front cover bracket 2 and the protective cover 7.

[0022] In another technical solution, the top drive front cover further includes a drive device, which is fixedly mounted on the front cover bracket 2 to drive the protective cover 7 to rotate relative to the front cover bracket 2. By driving the protective cover 7 to rotate, its rotation rate can be controlled, preventing the protective cover 7 from rapidly tilting downwards due to its own weight, which would affect the stability and safety of the top drive body.

[0023] Furthermore, the driving device includes a drive motor, a drum, and a wire rope; the drive motor is fixedly mounted on the upper end of the front cover bracket 2, and its output end is coaxially and fixedly connected to the drum; one end of the wire rope is wound on the drum, and the other end is fixedly connected to the upper end of the protective cover 7. The drive motor drives the drum to rotate, realizing the winding and unwinding of the wire rope, thereby causing the protective cover 7 to flip upward or downward; the flipping speed of the protective cover 7 can be adjusted by controlling the rotation speed of the drum.

[0024] The driving device can also be configured to include a drive motor, a driving sprocket, a transmission chain, and a driven sprocket. The bottom of the protective cover 7 is rotatably connected to the front cover bracket 2 via a rotating shaft 9, and the driven sprocket is fixedly sleeved on the rotating shaft 9. The output end of the drive motor is coaxially and fixedly connected to the driving sprocket. The transmission chain is sleeved on the driving sprocket and the driven sprocket. The bottom of the protective cover 7 is provided with multiple ear plates 8, and the rotating shaft 9 is fixedly inserted into the ear plates, with both ends rotatably connected to the ear plates on the front cover bracket 2. Each drive motor drives the driving sprocket to rotate, and then drives the driven sprocket to rotate via the transmission chain, thereby causing the protective cover 7 to flip upwards or downwards. The flipping speed of the protective cover 7 can be adjusted by controlling the rotation speed of the driving sprocket.

[0025] In another technical solution, the protective cover 7 is evenly provided with multiple heat dissipation holes. The protective cover is made of 6mm high-strength steel plate, and the heat dissipation holes enable ventilation and air permeability, facilitating heat dissipation for related components, while also reducing the weight of the protective cover 7. Preferably, the protective cover 7 also has a buffer pad layer on the side facing the front cover bracket 2 to prevent rigid contact with the components in the event of accidental impact. The buffer pad layer can be made of rubber pads, and the heat dissipation holes are symmetrically arranged.

[0026] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
