DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0025] See also Figure 1-7 The electroplating gantry crane specifically implemented includes a crane frame 1, a gantry frame 2 and two crane guide rails 5. The two sides of the crane frame 1 are guide rail arms 12 arranged on the top of the crane guide rails 5. The two guide rail arms 12 are fixedly connected by a crane crossbeam 11. The gantry frame 2 is vertically arranged inside the crane frame 1. A rotatable crane driving wheel 15 is arranged inside the guide rail arm 12. The crane frame 1 is movably connected to the top of the crane guide rail 5 through the crane driving wheel 15. The ends of the guide rail arms 12 are provided with guide wheel groups 13. The guide wheel groups 13 include an outer pulley 131 and an inner pulley 132. The side pulley 132, the outer pulley 131 and the inner pulley 132 are all horizontally rotatably arranged below the end of the guide rail arm 12, and the inner pulley 132 is arranged on the inner wall of the traveling guide rail 5, and the outer pulley 131 is arranged on the outer wall of the traveling guide rail 5. The outer pulley 131 and the inner pulley 132 are both truncated cone structures, and the outer pulley 131 and the inner pulley 132 are centrally symmetrical structures. The cross-section of the traveling guide rail 5 is a parallelogram structure, and the side walls of the outer pulley 131 and the inner pulley 132 respectively abut and slide against the side walls of the traveling guide rail 5.

[0026] A guide wheel group 13 consisting of an outer pulley 131 and an inner pulley 132 is provided at the guide rail arms 12 located on both sides of the carriage frame 1, wherein the outer pulley 131 and the inner pulley 132 are both truncated cone-shaped structures, and the outer pulley 131 and the inner pulley 132 are centrally symmetrical structures, and the cross-sectional structure of the carriage guide rail 5 is changed, so that the side walls of the outer pulley 131 and the inner pulley 132 respectively abut and slide against the side walls of the carriage guide rail 5. When the gantry crane shakes, the outer pulley 131 and the inner pulley 132 can form a larger contact area with the side of the carriage guide rail 5 for abutment, which can effectively prevent the carriage frame 1 and the carriage guide rail 5 from tilting and leaking, and has a high safety factor.

[0027] Specific as Figure 6As shown, the side walls of the two traveling guide rails 5 are tilted upwards away from the gantry 2, the end of the outer pulley 131 with a smaller opening is set upwards, and the end of the inner pulley 132 with a smaller opening is set downwards. When the electroplating gantry crane tilts due to the shaking of the electroplating equipment, the outer pulley 131 can be offset to the side of the inner pulley 132, and the cross-section of the traveling guide rail 5 is a parallelogram structure, which can play a fastening effect of the inverted structure, effectively preventing the outer pulley 131 from detaching from the outer wall of the traveling guide rail 5. At the same time, when the traveling guide rail 5 is running smoothly, the side wall of the inner pulley 132 is downwardly abutted against the inner wall of the traveling guide rail 5, which can play a supporting role, further spreading the vertical load-bearing force of the guide rail arm 12, so that the force of the traveling frame 1 in the vertical direction is more balanced.

[0028] Specific as Figure 2 As shown, a driving assembly 14 for driving the driving wheels 15 to rotate is provided inside the traveling cross beam 11. The driving assembly 14 includes a first motor 141 and a first rotating shaft 142. The two ends of the first rotating shaft 142 extend into the guide rail arms 12 on both sides respectively, and the ends of the first rotating shaft 142 are fixedly connected to the traveling driving wheels 15. The first motor 141 is arranged in the middle of the first rotating shaft 142, and the first motor 141 is drivingly connected to the first rotating shaft 142. The first motor 141 transmits the driving force to the traveling driving wheels 15 at both ends through the first rotating shaft 142, so that the traveling driving wheels 15 can drive the electroplating gantry traveling crane to move at the top of the traveling guide rail 5.

[0029] Specific as Figure 3 As shown, a horizontally arranged lifting beam 3 is provided in the middle part of the gantry 2, and vertically arranged lifting guide rails 21 are provided on both inner side walls of the gantry 2. The lifting beam 3 can move up and down along the lifting guide rails 21 inside the gantry 2, and a downwardly protruding clamping member 31 is provided at the bottom end of the lifting beam 3. The lifting beam 3 is used to fix the electroplating equipment through the clamping member 31. A horizontally arranged second rotating shaft 22 is provided at the top of the gantry 2. The second rotating shaft 22 is rotatably connected to the top of the gantry, and a second motor 23 is provided at one end of the second rotating shaft 22. The second motor 23 is transmission-connected to the second rotating shaft 22, and a clamping block 221 is provided in the middle part of the second rotating shaft 22. A connecting pillar 32 matching the clamping block 221 is provided on the top surface of the lifting beam 3, and a chain is provided between the clamping block 221 and the connecting pillar 32 for connection.

[0030] Specific as Figure 7As shown, sliding assemblies 33 are provided at both ends of the lifting beam 3, and the lifting beam 3 is movably connected to the lifting guide rail 21 through the sliding assemblies 33. The sliding assemblies 33 include a sliding plate 331 and a plurality of rollers 332. The sliding plate 331 is vertically fixedly connected to the end of the lifting beam 3, and the plurality of rollers 332 are rotatably arranged at the corners of the sliding plate 331, and the rollers 332 are slidingly connected to the lifting guide rail 21.

[0031] In a further embodiment, anti-collision components 4 are provided on both sides of the traveling frame 1, as shown in FIG. Figure 1 and Figure 4 As shown, the anti-collision component 4 is composed of an anti-collision frame 41, and the anti-collision frame 41 has a frame-like structure. A group of movable fixed blocks 42 are provided in the middle of the upper and lower edges of the anti-collision frame 41. A group of fixed blocks 42 includes two, and the two groups of fixed blocks 42 are respectively fixedly connected to the guide arm 12 and the gantry 2. A buffer component is provided inside one group of fixed blocks 42, and the guide arm 12 and the gantry 2 are movably connected to the anti-collision frame 41 through the fixed blocks 42.

[0032] The buffer assembly includes two buffer springs 43 and a limiting sleeve 44. The limiting sleeve 44 is fixedly connected to the middle of the upper and lower edges of the anti-collision frame 41. The buffer spring 43 is sleeved between the limiting sleeve 44 and the fixed block 42. One end of the buffer spring 43 abuts against the limiting sleeve 44, and the other end of the buffer spring 43 abuts against the inner wall of the fixed block 42. When the two electroplating gantries collide front and back, the anti-collision frames 41 of the two electroplating gantries may come into contact and compress the buffer spring 43 between the limiting sleeve 44 and the fixed block 42 to avoid a hard collision between the two electroplating gantries. This has a protective effect on the electroplating gantry and the electroplating equipment loaded inside the electroplating gantry.
