Description

Technical Field

[0001] This invention relates to the field of bucket wheel excavator technology, specifically to a bucket wheel excavator anti-collision device. Background Technology

[0002] Bucket wheel excavators, also known as bucket wheel stacker-reclaimers, are high-efficiency equipment for the continuous loading and unloading of bulk materials in modern industry. When using bucket wheel excavators, anti-collision devices need to be installed to prevent the cantilever of the bucket wheel excavator from colliding with objects during operation.

[0003] However, existing anti-collision devices suffer from tangled wires during wiring, hindering later maintenance. Furthermore, existing anti-collision devices cannot clean dust, failing to prevent dust from affecting the normal operation of the device. Therefore, those skilled in the art have provided anti-collision devices for bucket wheel excavators to address the problems mentioned in the background section. Summary of the Invention

[0004] The purpose of this invention is to provide a collision prevention device for bucket wheel excavators to solve the problems mentioned in the background art.

The wire-straightening assembly 9 includes an upper wire-straightening seat 11. A lower cable holder 12 is installed on the lower surface and is fixedly connected to the upper surface of the second mounting base 7. Semicircular grooves 13 are provided inside both the upper cable holder 11 and the lower cable holder 12. Connecting bolts 14 are connected through and engaged at both ends of the upper cable holder 11. The lower ends of the connecting bolts 14 are engaged inside the lower cable holder 12. Several rotating rods 15 are connected through and engaged on the upper surface of the upper cable holder 11. A spring 16 is fixedly connected to the lower end of the rotating rod 15. A cable-strapping block 17 is rotatably connected to the lower end of the spring 16. The spring 16 and the cable-strapping block 17 are both located inside the semicircular grooves 13. When connecting the wire 6, each wire 6 needs to be passed through the semicircular groove 13 in the cable-strapping assembly 9 first, and then the rotating rod 15 is rotated clockwise to clamp the wire 6 through the cable-strapping block 17 to prevent the wire 6 from getting tangled together and affecting later maintenance.

[0022] exist Figure 1 , Figure 4 and Figure 5In the first mounting base 1, a cleaning assembly 10 is provided on the right side surface. The cleaning assembly 10 includes a first fixing base 18 and a second fixing base 19. The first fixing base 18 and the second fixing base 19 are respectively fixedly connected to the front and rear side surfaces of the first mounting base 1. A lead screw 20 is installed inside the first fixing base 18. The lower end of the lead screw 20 is rotatably connected to a bearing seat 21. The bearing seat 21 is fixedly connected to the lower inner surface of the first fixing base 18. A connecting frame 22 is engaged with the outer surface of the lead screw 20.

The connecting frame 22, which is engaged with the lead screw 20, will drive the cleaning brush 23 to move up and down to wipe the transparent cover 3, so as to prevent the dust on the transparent cover 3 from affecting the normal scanning work of the laser scanner 5.

[0023] The working principle of this invention is as follows: When in use, the operator installs the device at the central axis position directly below the cantilever of the bucket wheel excavator through the fixing hole 8 on the second mounting base 7, and connects the wires 6 on the laser scanner 5. When connecting the wires 6, each wire 6 needs to be passed through the semi-circular groove 13 in the wire-straightening assembly 9, and then the rotating rod 15 is rotated clockwise to clamp the wires 6 through the wire-straightening block 17 to prevent the wires 6 from getting tangled and affecting later maintenance. The laser scanner 5 can scan the fan-shaped area in front. If there is an object in the fan-shaped area, the cantilever will be braked to prevent the cantilever from hitting the object and being damaged, thus playing a collision prevention role. The operator can periodically turn on the motor 25 in the cleaning assembly 10 to drive the lead screw 20 to rotate. The connecting frame 22, which meshes with the lead screw 20, will drive the cleaning brush 23 to move up and down to wipe the transparent cover 3, preventing the dust on the transparent cover 3 from affecting the normal scanning work of the laser scanner 5.
