Description

Technical Field

[0001] The utility model relates to the technical field of maintenance platforms, in particular to an anti-fall type wind power tower maintenance platform. Background Art

[0002] At present, wind is inexhaustible and it is a new energy with great potential. Therefore, wind power generation technology is increasingly valued by various countries. The device required for wind power generation is called a wind turbine. This wind turbine can be roughly divided into three parts: wind rotor (including tail rudder), generator and wind tower. The wind tower needs to be regularly inspected and maintained internally during use.

[0003] Taking into account the aging of the lifting mechanism, if the steel cable breaks when it rises to a certain height, the maintenance platform will fall rapidly, putting the maintenance personnel in danger and, in serious cases, causing casualties, posing a serious safety hazard. Utility Model Content

[0004] In order to solve the technical problem that when the steel cable breaks, the maintenance platform will fall rapidly, which will put the maintenance personnel in danger and even cause casualties in serious cases, thus posing a serious safety hazard, the utility model provides a fall-proof wind power tower maintenance platform.

[0005] The utility model is implemented by the following technical scheme: a fall-proof wind power tower maintenance platform, comprising a bracket and a platform, the top of the bracket is fixedly connected with a mounting plate, the mounting plate and the bracket are cooperated to install a lifting mechanism for lifting the platform, a railing is arranged on the top of the platform, a door leaf is hinged on one side of the railing, and a top plate is fixedly connected to the top of the railing, and a limiting mechanism is arranged inside the platform for preventing the platform from falling.

[0006] As a further improvement of the above scheme, the limiting mechanism includes limiting blocks fixedly connected to the front and rear sides of the bracket and a turntable fixedly installed inside the platform, the top of the turntable is fixedly connected to a connecting column, and the middle of the turntable is fixedly connected to a rotating rod, the connecting column is rotatably connected to the connecting rod, one end of the connecting rod is rotatably connected to the limiting rod, and the inside of the platform is fixedly connected to a fixed block for the limiting rod to slide.

[0007] Through the above technical solution, the turntable is rotated so that the limit rod is pushed out through the connecting rod and stuck in the limit block, so that the platform is further limited and the safety is improved.

[0008] As a further improvement of the above solution, the rotating rod passes through the top of the platform, and a protective box is hinged on the outer side of the rotating rod.

[0009] Through the above technical solution, the protective box prevents maintenance personnel from accidentally touching the rotating rod, making the anti-fall function ineffective.

[0010] As a further improvement of the above solution, the limit rod runs through both sides of the platform, and the limit rod and the limit block are arranged correspondingly.

[0011] As a further improvement of the above scheme, the lifting mechanism includes a slide groove opened on one side of the bracket and a winch fixedly installed on the top of the mounting plate, the slide groove is internally slidably connected to a slider fixedly connected to the platform, and the winch is fixedly connected to the top plate through a steel cable.

[0012] As a further improvement of the above solution, each rotation step of the winch corresponds to a limit block, and the corners of the limit block are provided with grooves corresponding to the limit rod.

[0013] Through the above technical solution, the use of the groove prevents the limiting rod from sliding off the side of the limiting block and losing the limiting function, which is practical.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model rotates the rotating rod, and the rotation of the rotating rod drives the rotating disk connected thereto to rotate. When the rotating disk rotates, the connecting rod is squeezed by the connecting column, so that the connecting rod pushes the limiting rod out of the fixed block and is inserted into the limiting block, thereby further limiting the platform to prevent the danger of steel cable breakage. The design strengthens the limitation of the platform through the use of the limiting rod and the limiting block, prevents the occurrence of dangerous conditions, and improves safety.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1 - Figure 3 A fall-proof wind power tower maintenance platform of this embodiment includes a bracket 1 and a platform 6. A mounting plate 2 is fixedly connected to the top of the bracket 1. A lifting mechanism is installed in cooperation with the bracket 1 for lifting the platform 6. A railing 7 is arranged on the top of the platform 6. A door leaf 9 is hinged on one side of the railing 7, and a top plate 8 is fixedly connected to the top of the railing 7. A limiting mechanism is arranged inside the platform 6 for preventing the platform 6 from falling.

[0024] Please combine Figure 1 and Figure 3 The limiting mechanism includes a limiting block 11 fixedly connected to the front and rear sides of the bracket 1 and a turntable 12 fixedly installed inside the platform 6. A connecting column 14 is fixedly connected to the top of the turntable 12, and a rotating rod 13 is fixedly connected to the middle of the turntable 12. The connecting column 14 is rotatably connected to a connecting rod 15, and one end of the connecting rod 15 is rotatably connected to a limiting rod 17. A fixed block 16 for the limiting rod 17 to slide is fixedly connected inside the platform 6.

[0025] By rotating the turntable 12, the limiting rod 17 is pushed out through the connecting rod 15 and stuck in the limiting block 11, so that the platform 6 is further limited, thereby improving safety.

[0026] Please combine Figure 3 The rotating rod 13 passes through the top of the platform 6 , and a protective box 18 is hinged on the outer side of the rotating rod 13 .

[0027] The function of the protection box 18 is to prevent the maintenance personnel from accidentally touching the rotating rod 13, which would render the anti-falling function ineffective.

[0028] Please combine Figure 1 The limiting rod 17 passes through both sides of the platform 6 , and the limiting rod 17 and the limiting block 11 are arranged correspondingly.

[0029] Please combine Figure 1 and Figure 2 The lifting mechanism includes a slide groove 4 opened on one side of the bracket 1 and a winch 3 fixedly installed on the top of the mounting plate 2. The inside of the slide groove 4 is slidably connected with a slider 5 fixedly connected to the platform 6. The winch 3 is fixedly connected to the top plate 8 through a steel cable 10.

[0030] Please combine Figure 1Every step of the winch 3 rotation corresponds to the limit block 11 , and the corners of the limit block 11 are provided with grooves corresponding to the limit rod 17 .

[0031] The use of the groove prevents the limiting rod 17 from sliding off the side of the limiting block 11 and losing the limiting function, and is practical.

[0032] The implementation principle of an anti-fall type wind power tower maintenance platform in the embodiment of the present application is as follows: when working, the platform 6 is lifted and lowered by pulling the winch 3 and the steel cable 10, the use of the slide 4 and the slider 5 makes the platform 6 stable, the use of the railing 7 plays a protective role, and the top plate 8 is used to prevent falling objects from heights. After the lifting is completed, the protection box 18 is opened, and the rotating rod 13 is rotated. The rotation of the rotating rod 13 drives the turntable 12 connected thereto to rotate. When the turntable 12 rotates, the connecting rod 15 is squeezed through the connecting column 14, so that the connecting rod 15 pushes the limiting rod 17 out of the fixed block 16 and inserts it into the limiting block 11, thereby further limiting the platform 6 and preventing the steel cable 10 from breaking and causing danger.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
