Description

Technical Field

[0001] The utility model relates to an automatic plate turning device, in particular to an automatic plate turning device for a sliding wire cover. Background Art

[0002] As the power supply device of the crane, the sliding wire is generally fixed in the groove below the ground. The cable is connected by sliding and fixing to provide power for the gantry crane. When the crane is running, the contact is driven to slide on the sliding wire, thereby providing uninterrupted power for the crane. Because the sliding wire is energized, in order to prevent people and objects from falling into the groove, it is necessary to install several covers on it flush with the ground. The covers need to be opened manually when the crane is running, and closed manually when the crane stops. The covers can only be fully opened or fully closed, which can easily cause personal injury and equipment damage accidents. At the same time, the manual flipping operation of personnel is high-intensity and cumbersome, which reduces work efficiency. Utility Model Content

[0006] The support frame is connected to a plurality of flap wheels, and the plurality of flap wheels are distributed in an arch shape;

[0007] The highest point of the wheel rim of the flap wheel located on the lower side is higher than the center of the circle of the flap wheel adjacent to it on the upper side, and is lower than the highest point of the wheel rim of the flap wheel adjacent to it on the upper side.

[0008] In the automatic flipping device for a sliding wire cover, the diameters of the rims of the flipping wheels among the plurality of flipping wheels distributed in an arch shape increase successively from the bottom of the arch to the top of the arch.

[0009] The automatic flipping device for a sliding wire cover, the flipping wheel comprises a rim, the center of the rim is rotatably connected to a pin, and the pin is fixed on the support frame.

[0010] The automatic flipping device for a sliding wire cover, wherein the support frame is a triangular support structure.

[0011] The automatic flipping device for a sliding wire cover, wherein the fixed shaft is fixed to the crane.

[0012] In the automatic flipping device for a sliding wire cover, a radar for detecting obstacles ahead and a camera for observing the ahead scene in real time are installed on the convex head. Beneficial Effects

[0013] 1. The utility model has a simple structure and high stability. When the crane is running, the automatic flap device can be driven to open or close a single sliding cover, so that the cover at the operating position is automatically opened and the covers at other positions are all automatically closed.

[0014] 2. The support frame of the utility model is provided with a camera and a radar. The camera can transmit the video of the picture in front of the flap device to the crane cab, providing the driver with real-time pictures and realizing artificial early warning. When the radar detects an obstacle in front, it can automatically stop and send out an alarm signal to prevent personal injury and equipment damage accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Reference Figure 1-Figure 2 , an automatic flipping device for a sliding wire cover, characterized in that: it comprises a support frame 5 and a convex head 9, the convex head is fixed to the top of the support frame, the convex head is a rectangular convex head, and the end of the convex head is fixedly connected to the fixed shaft 4;

[0019] The support frame is connected with a plurality of flap wheels 3;

[0020] The fixed shaft is fixed to the crane;

[0021] The energized sliding line 6 is fixed in the cable trench through a bracket, and a number of cover plates 7 flush with the ground are installed on the top. Hinges 8 are installed on the cover plates 7, and the cover plates 7 can be flipped open by the hinges 8. The automatic flap device is connected to the crane through a fixed shaft 4 and is arranged between the ground and the cable trench. The sliding line 6 is connected to the interior by cables in a sliding and fixed manner. Electricity is supplied to the crane through the sliding line → automatic flap device. This sliding power supply principle and specific connection structure belong to the prior art and are not described in detail here. When the crane moves horizontally, the automatic flap device is close to the bottom of the sliding line cover plate 7, and the cover plate 7 is automatically and smoothly opened through the rotating support of the flap wheel. After the automatic flap device passes through the cover plate at the highest point, the cover plate gradually and automatically falls smoothly through the flap wheel 3 due to gravity, so that the cover plate in the operating position is automatically opened and the covers in other positions are all automatically closed. Example

[0022] The plurality of flap wheels are distributed in an arch shape, the flap wheels include a rim 31, the rim center is rotatably connected to a pin shaft 32, the pin shaft is fixed to the support frame, the support frame is a triangular support structure, the fixed shaft is fixed to a crane (not shown), the flap wheels corresponding to the two sides of the arch are symmetrically arranged, the plurality of flap wheels are distributed in an arch shape, and the arch top faces upward, the highest point of the rim of the flap wheel on the lower side is higher than the center of the circle of the adjacent upper flap wheel, and lower than the highest point of the rim of the adjacent upper flap wheel, so that the cover The plate is prevented from getting stuck when it switches from the lower flap wheel to the adjacent upper flap wheel. When the crane moves horizontally, the automatic flap device approaches the bottom of the sliding wire cover plate 7, and the cover plate 7 is automatically and smoothly opened through the rotation support of the flap wheel. As the crane continues to move, the flap wheels at different positions contact the bottom of the cover plate, making the cover plate opening angle gradually larger. After the highest point of the automatic flap device passes through the cover plate, the cover plate gradually and automatically falls smoothly through the flap wheel 3 due to gravity, so that the cover plate at the operating position is automatically opened and the cover plates at other positions are all automatically closed. Example

[0023] Different from the first embodiment, in order to enable the cover plate to be quickly flipped, the diameters of the flap wheel rims of the plurality of flap wheels distributed in an arch shape increase successively from the arch bottom to the arch top; Example

[0024] Different from Example 1 or 2, in order to avoid personal injury and equipment damage accidents, the convex head is installed with a radar 2 for detecting obstacles in front and a camera 1 for observing the front picture in real time. When the flap device is in operation, the camera 1 and the radar 2 enter the working state. The camera 1 can transmit the picture video in front of the flap device to the crane cab, providing the driver with a real-time picture to realize artificial early warning; when the radar 2 detects an obstacle in front, it can automatically stop and send out an alarm signal to prevent equipment damage accidents.
