Description

Technical Field

[0001] The utility model relates to the technical field of lifting double-beam cranes, and more particularly to a lifting double-beam crane. Background Art

[0002] Under existing technical conditions, in order to ensure the stability and safety of roller rotation during operation, double-girder cranes usually need to install jackets to fix the rollers. However, this design has certain shortcomings. During the use of double-girder cranes, the friction between the jackets and the slide rails often produces loud noise, which not only affects the use of the crane, but may also interfere with the working environment. This noise is mainly caused by the continuous contact and relative movement between the jackets and the slide rails, which increases the friction and causes noise problems.

[0003] Furthermore, the noise problem caused by the friction between the jacket and the slide rail has a significant impact on the user experience and working environment of the double-girder crane. In noisy workplaces, this additional noise source may aggravate the noise pollution in the working environment, affecting not only the comfort of the operator but also the health of surrounding personnel. In addition, the noise generation may also mask other problems that may arise during the operation of the crane, increasing safety risks. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the utility model provides a lifting double-beam crane with the following beneficial effects:

[0017] 1. The design of the lubrication mechanism significantly improves the stability and reduces noise of the lifting double-girder crane during use. Through the coordination of the slide rail, mobile car, roller and jacket, and the connection of the oil inlet pipe and the oil outlet pipe, real-time lubrication of the contact surface between the roller and the slide rail is achieved. This design effectively reduces the friction between the roller and the slide rail during movement, reduces noise generation, and improves the operation quality of the crane. The setting of the sealing plate and the raised sleeve ensures that the lubricating oil can be quickly released when needed, while avoiding unnecessary lubricating oil leakage and keeping the working environment clean.

[0018] 2. The oil delivery mechanism provides a mechanism for precisely controlling the flow of lubricating oil through the combination of a sealing disc, a raised sleeve, and a guide rod. The setting of the hexagonal groove and thrust bearing enables the operator to release and stop the lubricating oil by simply turning the raised sleeve. This design not only makes the lubrication process more controllable, but also allows the lubricating oil supply to be adjusted according to actual needs, thereby optimizing the lubrication effect, reducing resource waste, and extending the service life of the crane.

[0019] 3. The adjustment mechanism achieves fine adjustment of the oil output through the cooperation of the hexagonal rod and the threaded sleeve. The arrangement of the through groove, the pressure rod, and the sealing rod allows the operator to adjust the supply pressure and flow of the lubricating oil according to the actual friction between the roller and the slide rail. The beneficial effect of this adjustment mechanism is that it provides a flexible and responsive lubrication control system, ensuring the optimal lubrication state of the crane under various operating conditions, further reducing operating noise, and improving the operating comfort and work efficiency of the crane. In this way, the adjustment mechanism enhances the overall performance of the lubrication system, providing a more reliable and efficient operation guarantee for the crane.

Fixed holes 8 are respectively opened on both sides of the slide rail 2, and each fixed hole 8 is divided An oil outlet pipe 7 is separately installed, and the oil outlet mechanism and the adjustment mechanism are respectively installed on the oil outlet pipe 7. The oil outlet mechanism includes a sealing disk 9 and a raised sleeve 10. The sealing sleeve is fitted on the inner wall of the oil outlet pipe 7. The raised sleeve 10 is installed on the sealing disk 9. The raised sleeve 10 is fitted on the inner wall of the jacket 6. Each raised sleeve 10 is respectively provided with a hexagonal groove 11. A guide rod 101 is respectively installed on each raised sleeve 10, and a bottom sleeve 101 is installed in the oil outlet pipe 7. The guide rod 101 is slidably connected in the bottom sleeve 101. A spring 12 is sleeved on the guide rod 101, and a thrust bearing 13 is provided on the spring 12. The thrust bearing 13 is sleeved on the guide rod 101, and the thrust bearing 13 is in contact with the bottom sleeve 102.

[0030] The adjusting mechanism includes a hexagonal rod 14 and a threaded sleeve 15. The hexagonal rod 14 is installed on the guide rod 101. The threaded sleeve 15 is threadedly connected to the oil outlet pipe 7. The hexagonal rod 14 is slidably connected to the threaded sleeve 15. A plurality of pressure rods 16 and sealing rods 17 are equidistantly provided on the sealing disk 9. A plurality of through grooves 18 are equidistantly provided on the threaded sleeve 15. The plurality of through grooves 18 and the pressure rods 16 and the sealing rod 17 are coaxially arranged.

[0031] When the trolley 3 moves, the roller 5 rotates along the slide rail 2, and then the jacket 6 fits against the side wall of the slide rail 2. When the jacket 6 contacts the raised sleeve 10, it pushes the sealing plate 9 to move backward, and then releases the seal between the sealing plate 9 and the oil outlet pipe 7. Since the lubricating oil is introduced into the multiple oil outlet pipes 7 through the oil inlet pipe 4, the pressure rod 16 is slidably connected in the through groove 18 at this time. As the pressure rod 16 and the sealing rod 17 move backward, the space between the threaded sleeve 15 and the sealing plate 9 is reduced, and then the lubricating oil at the rear end is squeezed and flows into the threaded sleeve 15 and the sealing plate 9 through the through groove 18 at the lower end of the sealing rod 17. Then the space between the threaded sleeve 15 and the sealing plate 9 is also reduced, so it will be discharged through the gap between the sealing plate 9 and the oil outlet pipe 7, thereby completing the lubrication process. By introducing lubricating oil into the side wall of the jacket 6, the noise during rotation is reduced, thereby improving the use effect.

[0032] See also Figure 1-5 , as an implementation method of a lifting double-girder crane for the adjustment mechanism:

[0033] More specifically, when lubrication is not needed, it is only necessary to rotate the raised sleeve 10. Since the hexagonal rod 14 is connected to the raised sleeve 10, it will drive the threaded sleeve 15 to rotate, and then make multiple sealing rods 17 and pressure rods 16 slide and connect in the through groove 18 respectively. When the raised sleeve 10 is compressed, it will not connect the two sides of the threaded sleeve 15, so no oil will be discharged, thereby completing the adjustment process.

[0034] In summary, when the overall equipment is in use or running: when the mobile car 3 moves, the roller 5 rotates along the slide rail 2, and then the sleeve 6 fits against the side wall of the slide rail 2. When the sleeve 6 contacts the raised sleeve 10, it pushes the sealing plate 9 to move backward, and then releases the seal between the sealing plate 9 and the oil outlet pipe 7. Since lubricating oil is introduced into multiple oil outlet pipes 7 through the oil inlet pipe 4, the pressure rod 16 is slidably connected in the through groove 18 at this time. As the pressure rod 16 and the sealing rod 17 move backward, the space between the threaded sleeve 15 and the sealing plate 9 is reduced, and then the lubricating oil at the rear end is squeezed and flows into the threaded sleeve 15 and the sealing plate 9 through the through groove 18 at the lower end of the sealing rod 17. Then the space between the threaded sleeve 15 and the sealing plate 9 is also reduced, so it will be discharged through the gap between the sealing plate 9 and the oil outlet pipe 7, thereby completing the lubrication process. By introducing lubricating oil into the side wall of the jacket 6, the noise during rotation is reduced, thereby improving the effect of use.

[0035] When lubrication is not needed, it is only necessary to rotate the raised sleeve 10. Since the hexagonal rod 14 is connected to the raised sleeve 10, it will drive the threaded sleeve 15 to rotate, and then make the multiple sealing rods 17 and the pressure rod 16 slide and connect in the through groove 18 respectively. When the raised sleeve 10 is compressed, it will not connect the two sides of the threaded sleeve 15, so no oil will be discharged, thereby completing the adjustment process.
