DETAILED DESCRIPTION

[0016] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0017] Example: See Figure 1-2 The utility model provides a technical solution: a new type of suspension end beam suspension crane. This solution takes into account that the existing suspension crane has many components, and the steps are complicated during assembly and installation, which increases the workload and increases the production cost. Based on the above content, this case sets the following technical means;

[0018] Specifically, the device at least includes a main beam 1, an electric control box 2, an electric hoist 3, a pair of end beams 4, two pairs of fixed plates 5, two pairs of structural support rods 6, a mobile drive motor 7, two pairs of rotating shafts 8, a driving wheel 9 and three passive wheels 10;

[0019] The main beam 1 connects and supports the entire equipment. When in use, it is moved and controlled through the flashlight 12. After receiving the control signal, the electric control box 2 will control the electric hoist 3 connected to it through the cable to move. The roller drive structure on the electric hoist 3 will move laterally on the I-shaped structure track of the main beam 1, and cooperate with the electric hoist 3 to lift the object. At the same time, the mobile structure composed of the mobile drive motor 7, the active wheel 9 and the passive wheel 10 is started. The mobile drive motor 7 drives the active wheel 9 to rotate through the rotating shaft 8. The active wheel 9 installed on the end beam body 4 will cooperate with the other three passive wheels 10 without driving force to drive the end beam body 4 to move forward and backward on the track frame, thereby driving the main beam 1 to move forward and backward through the end beam body 4 to drive the hoisted object to move in multiple directions.

[0020] To be more specific, a pair of end beams 4 are installed on the upper wall surface of the end of the main beam 1, two pairs of fixed plates 5 are installed on the lower wall surface of the pair of end beams 4, two pairs of structural support rods 6 are fixedly installed in the middle position of the pair of end beams 4, the mobile drive motor 7 is installed on one of the outer wall surfaces of the pair of end beams 4, two pairs of rotating shafts 8 are embedded in the inner wall surface of the pair of end beams 4, one of the two pairs of rotating shafts 8 is connected to the output end of the mobile drive motor 7, the driving wheel 9 is installed on the rotating shaft 8 connected to the output end of the mobile drive motor 7, and the three passive wheels 10 are installed on the other three of the two pairs of rotating shafts 8.

[0021] In a specific implementation process, further, the electric hoist 3 is connected to the electric control box 2 through a cable, and a cable moving frame 11 is installed on the main beam 1.

[0022] In the specific implementation process, further, the electric hoist 3 is connected with a flashlight switch 12 to facilitate the staff to carry out mobile control at any time on the ground.

[0023] In the specific implementation process, further, two pairs of structural support rods 6 are fixed on a pair of end beams 4 through fixing nuts 13, and the two side walls of the end beams 4 are installed with fixing nuts 13. By arranging fixing nuts 13 on both sides of the end beams 4, the equipment is prevented from loosening due to vibration during use.

[0024] In the specific implementation process, further, the main beam 1 has an I-shaped structure.

[0025] In the specific implementation process, further, anti-collision blocks 14 are provided at both ends of a pair of end beams 4 to prevent the end beams from colliding with the ends of the moving rails during continuous movement, thereby ensuring the safety of the equipment.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
