In order to meet market demand, customers need to purchase multiple sets of equipment, each set of equipment cannot be effectively used, and the cost increases exponentially.

[0003] In view of the shortcomings of the prior art, it is urgent to develop a crane suitable for loading and unloading bars of different lengths within a wide range of 800mm-7500mm. Utility Model Content

DETAILED DESCRIPTION

[0020] Now the utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model. Example

[0021] like Figure 1 - Figure 4 As shown, this embodiment 1 discloses an ultrasonic flaw detection crane suitable for long and short bars, including a crane body 1, a fixed boom device 2 and a movable boom device 3. The fixed boom device 2 and the movable boom device 3 are both installed on the crossbeam 13 of the crane body 1.

[0022] Among them, the fixed boom device 2 includes a cylinder, a lifting guide rail and a first manipulator, etc., which is a traditional boom structure in the ultrasonic flaw detection industry and will not be described in detail here.

[0023] The mobile boom device 3 is composed of a first bracket assembly 9, a transverse chain 11, a gear 12 and a motor 6, a second bracket assembly 10 vertically movable relative to the first bracket assembly 9, a cylinder 8, a second manipulator 5, etc. The transverse chain 11 is installed on the crossbeam 13 of the traveling main body 1, and the transverse chain 11 is connected with the gear 12, and the gear 12 is driven to rotate by the motor 6. Some links of the transverse chain 11 are fixed with a base, and the first bracket assembly 9 includes a longitudinal bracket 14, a transverse bracket 15 located at both ends of the longitudinal bracket 14, and a vertical bracket 16 connected to the transverse bracket 15. The transverse brackets 15 at both ends of the longitudinal bracket 14 are respectively fixedly connected to the bases installed on the transverse chains 11 on the two crossbeams 13. When the motor 6 drives the gear 12 to rotate so that the transverse chain 11 is running, the first bracket assembly 9 moves horizontally along the crossbeam 13, so that the second manipulator 5 cooperates with the first manipulator 4 to pick up and put the flaw detection material with a length range of 800mm to 7500mm.

[0024] The motor 6 is a motor with an encoder.

[0025] The second bracket assembly 10 moves vertically relative to the first bracket assembly 9 as follows: the second bracket assembly 10 includes two second vertical brackets 17 and a transverse frame 18 connecting the two second vertical brackets 17. A guide rail 19 is installed on the outer wall of the second vertical bracket 17, and a slider 20 that can slide with the guide rail 19 is installed on the inner wall of the vertical bracket 16 of the first bracket assembly 9. The main body of the cylinder 8 is installed on the transverse bracket 15 of the first bracket assembly 9. The end of the piston of the cylinder 8 is connected to the second vertical bracket 17. The lifting movement of the cylinder 8 drives the entire second bracket assembly 10 to move vertically. The transverse frame 18 at the bottom of the second bracket assembly 10 is connected to the second manipulator 5, thereby driving the second manipulator 5 to move vertically.

[0026] In order to enable the movable boom device 3 to accurately return to the starting point, sensors 7 are respectively installed at both ends of the same side of the crossbeam 13 for detecting the accurate position of the movable boom device 3 .

[0027] The operating principle of this embodiment is as follows:

[0028] When the length of the flaw detection bar is 800mm, the program sets the first manipulator 4 of the fixed boom device 2 to act alone, and the second manipulator 5 does not act. When the length of the flaw detection bar is >800mm, the mobile boom device 3 drives the gear 12 through the motor 6, moves to the specified position according to the feedback value of the encoder carried by the motor 6, and locks it. The fixed boom device 2 and the mobile boom device 3 respectively realize the lifting and lowering control of the first manipulator and the second manipulator through the extension and retraction of their respective cylinders 8, and the first manipulator and the second manipulator grab or put down the bar. The program sets the position of the sensor 7 as the origin. When the length needs to be switched, the mobile boom device 3 needs to move to the position of the sensor 7 through the motor 6 to reset to ensure the accuracy of the position.

[0029] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the previous specific implementation methods after reading the description without departing from the essence and scope of the utility model.
