Description

Technical Field

[0001] The present invention relates to the technical field of tower cranes, and more particularly to a tower crane capable of resisting wind swing. Background Art

[0002] Existing Chinese patent: A stable tower crane cab (CN217264380U), through the structural design of the reinforcement frame, the room body is made more solid on both sides by adding the reinforcement frame, and the reinforcement frames on both sides of the room body are connected by the connecting frame, so that the stability of the room body is better; because the boom of the tower crane is relatively long and arranged horizontally, the stability of the boom is relatively low and the wind resistance area is large. When the wind is strong, the boom will swing after being hit by the strong wind, which poses a great safety hazard. At the same time, the staff cannot quickly obtain the view below in the existing crane cab, which is inefficient.

[0003] The above matters described as background technology are only used to enhance the understanding of the background of the invention and should not be interpreted as admitting that they are prior art known to those skilled in the art.

At the same time, the pedal 309 drives the pressure sensor 3017 downward to contact the third round rod 3020. 3020, the pressure sensor 3017 transmits a signal to the control console 6 after receiving pressure, and the control console 6 issues an alarm to warn the staff not to stand on the pedal 309. When in use, the pressure sensor 3017 detects the irregular operation of the staff standing on the pedal 309, and warns the staff not to stand on the pedal 309, so as to avoid excessive force on the transparent part 302 and improve safety performance. At the same time, the second round rod 3018 and the support block 3021 cooperate to limit the movement of the pressure sensor 3017, so as to protect the pressure sensor 3017;

[0056] When the staff puts both feet on the upper side of the pedal 309, the sand on the sole falls into the groove 91, the second motor 3024 is started, the second motor 3024 drives the third transmission rod 3023 to rotate, the third transmission rod 3023 drives the cam 3025 to rotate, the cam 3025 drives the elastic telescopic rod 3026 to perform a circular motion, the elastic telescopic rod 3026 drives the linkage rod 3027 to perform a circular motion, so that the linkage rod 3027 intermittently hits the pedal 309, thereby shaking the sand in the groove 91 into the first cavity 92 for collection, and the sand on the sole of the staff is automatically collected into the first cavity 92 during use, so as to prevent the sand from falling onto the transparent part 302 to block the field of vision, and the sand is diverted to the groove 91 through the guide strip 3028 to prevent the sand from remaining on the upper side of the pedal 309, so as to realize automatic and efficient collection of sand;

[0057] When the pedal 309 drives the parts thereon to flip upward, the sand is automatically transferred from the first cavity 92 to the second cavity 93 to prevent the sand from pouring out during the flipping process. Then, the cover plate 3030 is manually taken out upward, and the cover plate 3030 drives the latch 3031 to move upward, and the latch 3031 drives the elastic bead 3032 to move upward, so that the latch 3031 and the elastic bead 3032 are away from the frame 3022. Then, the sand in the first cavity 92 and the second cavity 93 are manually cleared, so that when the pedal 309 drives the parts thereon to flip upward, the sand is automatically transferred from the first cavity 92 to the second cavity 93 to prevent the sand from pouring out during the flipping process.

[0058] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
