Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane sealing technology, and in particular to a flexible bonding component for a clean crane trolley sealing structure. Background Technology
[0002] The primary purpose of using a sealed structure in a cleanroom crane is to prevent dust, dirt, and other contaminants from entering the critical components of the equipment, ensuring its normal operation and long-term stable operation in a high-cleanliness environment. The sealed structure effectively isolates external contaminants, protecting the crane's mechanical, electronic, and lubrication systems, preventing malfunctions and increased maintenance costs. The sealed structure is closely related to flexible bonding components, typically used at the joints of the sealed structure. These flexible bonding components adapt to dynamic changes during crane movement, maintaining a long-term effective seal and ensuring that the seal will not fail due to equipment movement or minor deformation, thus providing more reliable protection.
[0003] The flexible sealing components of existing crane cleanroom crane sealing structures utilize their flexibility and elasticity to provide sealing and protection during crane movement. These flexible components are typically made of highly elastic materials, allowing them to deform according to the dynamic changes of the equipment. This ensures that the sealing structure remains tightly sealed during movement or vibration, preventing external contaminants from entering the equipment. The flexible component design allows it to adapt to the relative movement of various crane components, ensuring that the sealing effect is not affected by minor displacements of mechanical parts, thereby effectively extending the equipment's service life and reducing maintenance requirements.
[0004] In existing technologies, some cleanroom cranes suffer from a problem: a lack of effective handling of external contaminants on the lifting ropes. During operation, the lifting ropes are exposed to the external environment, easily accumulating dust, oil, chemicals, and other contaminants. Especially in clean environments, once these contaminants adhere to the lifting ropes, they can be carried into sensitive areas, polluting the working environment or affecting the normal operation of the equipment. Due to the lack of effective cleaning or protective measures, the accumulation of these contaminants leads to equipment malfunctions, contaminant spread, and increased maintenance costs. Therefore, a flexible, fitted component for the sealing structure of a cleanroom crane is proposed to address these issues. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a flexible fitting component for the sealing structure of a crane clean trolley, which aims to improve the problem in the prior art where some crane clean trolleys lack the treatment of dirt on the outside of the lifting rope, causing dirt to be brought into sensitive areas, polluting the working environment or affecting the normal operation of the equipment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flexible fitting component of a clean crane trolley sealing structure, including a crossbeam, a transverse adjustment mechanism fixedly connected inside the crossbeam, a longitudinal adjustment mechanism slidably connected to the top of the crossbeam, and a longitudinal beam slidably connected to the bottom of the crossbeam;
[0007] The lateral adjustment mechanism includes a lateral adjustment motor, which is fixedly connected inside the crossbeam. A drive helical gear is fixedly connected to the drive end of the lateral adjustment motor. A working helical gear is rotatably connected inside the crossbeam.

A working shaft is rotatably connected inside the crossbeam. A belt is rotatably connected to the rotating shaft and the working shaft. A sliding wheel is fixedly connected to the rear side of the working shaft.
[0008] As a further description of the above technical solution: the longitudinal adjustment mechanism includes an adjustment block, which is slidably connected to the top of the crossbeam. Two longitudinal adjustment motors are fixedly connected inside the adjustment block. The drive end of the longitudinal adjustment motor is fixedly connected to a bidirectional shaft. Adjustment shafts are rotatably connected to both sides inside the adjustment block. A second belt is internally coupled to the adjustment shaft and the bidirectional shaft. A second sliding wheel is fixedly connected to the rear side of the adjustment shaft. The second sliding wheel is rotatably connected to both sides of the crossbeam. A lifting assembly is fixedly connected inside the adjustment block.
[0009] As a further description of the above technical solution: the lifting assembly includes a lifting drive motor, the lifting drive motor is fixedly connected inside the crossbeam, the driving end of the lifting drive motor is fixedly connected to a lifting shaft, a lifting rope is rotatably connected inside the lifting shaft, a lifting hook is fixedly connected to the bottom of the lifting rope, a protective block is fixedly connected to the bottom of the adjusting block, and the lifting rope is fixedly connected inside the protective block.
[0010] As a further description of the above technical solution: a sliding groove is provided inside the longitudinal beam, and the sliding wheel is rotatably connected in the sliding groove;
[0011] As a further description of the above technical solution: support blocks are provided on both sides of the crossbeam, and sliding grooves are provided inside the support blocks, with the second sliding wheel rotatably connected in the sliding grooves;
[0012] As a further description of the above technical solution: the crossbeam has a rotating groove inside, the working helical gear and the driving helical gear are rotatably connected in the rotating groove, and the working shaft is rotatably connected in the rotating groove;
[0013] As a further description of the above technical solution: a sealing groove is provided inside the protective block, and the lifting rope is fixedly connected in the sealing groove;
[0014] As a further description of the above technical solution: four limiting support blocks are fixedly connected to the bottom of the crossbeam, and the sliding wheel is rotatably connected inside the limiting support blocks.
[0015] This utility model has the following beneficial effects:
[0016] 1. The transverse adjustment motor located inside the crossbeam starts, thereby driving the drive helical gear to rotate, which in turn drives the working helical gear to rotate. Through the rotating shaft behind the working helical gear and the belt inside the rotating shaft, the two working shafts are driven to rotate, which in turn drives the two sliding wheels to rotate, causing the crossbeam to slide on the top of the longitudinal beam. At the same time, because the entire drive mechanism is located inside the crossbeam, the impact of the device on the outside is minimized, thereby reducing the impact on dust.
[0017] 2. In this utility model, when lifting is required, the lifting drive motor starts, causing the lifting shaft to rotate, thereby releasing the restriction on the lifting rope. The lifting rope causes the lifting hook located at the bottom of the lifting rope to slide, thereby causing the heavy object to slide, thus achieving the lifting effect. During this process, because the lifting rope is located inside the protective block, the lifting rope is not affected by dust or other dirt, and dirt on the outside of the lifting rope will not fall into the external environment, thus achieving a sealing effect.

This causes the crossbeam 1 to slide on the top of the longitudinal beams 9, thereby realizing the adjustment of the crossbeam 1.
[0030] Then, the longitudinal adjustment motor 17 located inside the adjustment block 10 starts, driving the bidirectional shaft 16 to rotate.
