A monorail is a transportation device that runs on a suspended monorail. It consists of a drive vehicle or traction vehicle (such as one for wire rope traction), a braking vehicle, and a load-bearing vehicle. Monorails typically use a specially made I-beam suspended above the tunnel as a track. Various types of suspended vehicles are connected to form a train, which runs along the track by traction equipment. Speed ​​reducers are required during the use of monorails. Oil outlet structures are needed in the speed reducers used in monorails to improve their performance.

[0003] However, most existing technical solutions have the following drawbacks:

[0004] 1. When installing the speed reducer, it is installed on the monorail by welding. In actual use, the disassembly efficiency of the speed reducer is low.

[0005] 2. Ordinary speed reducers are not effective at removing lubricating oil, which affects their performance.

[0006] 3. The internal maintenance of the reducer is not convenient enough. Therefore, this utility model provides a reducer for monorail cranes to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a speed reducer for monorail cranes, in order to solve the problems mentioned in the background art, which are that the speed reducer is installed on the monorail crane by welding. In actual use, the disassembly efficiency of the speed reducer is low, the ordinary speed reducer has poor lubrication removal effect, thus affecting the performance of the speed reducer, and the internal maintenance of the speed reducer is not convenient.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a reducer for a monorail crane, comprising a reducer housing, wherein the reducer housing is installed on the front side of the monorail crane, and a reduction gear set is movably installed inside the reducer housing;

[0009] Also includes:

[0020] Compared with the prior art, the beneficial effects of this utility model are: the reducer for monorail cranes is easy to install, easy to remove lubricating oil, and easy to maintain the internal parts of the reducer;

[0021] 1. By placing the reducer housing on the front side of the monorail, the reducer housing drives the fixing block to fit against the front side of the monorail, thereby causing the reduction gear set to drive the connecting shaft to engage and install on the outer front end of the monorail drive shaft. Rotating the connecting rod causes the connecting rod to be threaded on the outer side of the middle part of the connecting shaft, thereby causing the connecting rod to be threaded on the outer front end of the monorail drive shaft. Rotating the fixing rod causes the fixing rod to be threaded on the outer rear end of the fixing block, thereby causing the fixing rod to be threaded on the monorail housing, which facilitates the installation of the reducer housing.

[0022] 2. By rotating the mounting rod, the mounting rod is threaded onto the upper outer side of the moving block, causing the mounting rod to slide outwards from the upper end of the moving block. This allows the mounting rod to separate from the middle outer side of the cover plate. Pulling the moving block outwards causes the moving block to extend the spring, allowing the moving block to slide outwards from the lower outer side of the cover plate. This allows the moving block to separate from the upper outer side of the reducer housing. Pulling the cover plate upwards causes the cover plate to separate from the connecting block on the upper side of the reducer housing, facilitating internal maintenance of the reducer housing.

[0023] 3. By rotating the connecting rod, the connecting rod is threaded onto the outer left side of the connecting plate, causing the connecting rod to slide outwards from the left side of the connecting plate. This allows the connecting rod to separate from the outer right side of the reducer housing. Then, pull the connecting plate to the right, causing the connecting plate to separate the blocking plate from the lower right side of the reducer housing, facilitating the removal of lubricating oil from inside the reducer housing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a reducer for a monorail crane, comprising: a reducer housing 1 installed on the front side of the monorail crane, and a reduction gear set 2 movably installed inside the reducer housing 1; a cover plate 5 movably installed on the upper outer side of the reducer housing 1, and an oil inlet 6 opened on the upper left side of the cover plate 5; a connecting block 12 fixedly installed on the lower inner side of the cover plate 5; a heat dissipation hole 7 opened in the middle of the cover plate 5; and filter screens 8 provided on both the lower middle side of the cover plate 5 and the upper side of the oil inlet 6, with a gap between the oil inlet 6 and the filter screen 8. The cover plate 5 has a detachable structure. A limiting structure is fixedly installed on the lower outer side of the cover plate 5. Rotating the limiting structure separates the limiting structure from the upper outer side of the reducer housing 1. Pulling the cover plate 5 upward causes the cover plate 5 to drive the connecting block 12 to separate from the upper side of the reducer housing 1, which facilitates maintenance of the inside of the reducer housing 1. The heat dissipation hole 7 opened on the middle side of the upper end of the reducer housing 1 facilitates heat dissipation of the inside of the reducer housing 1. The oil inlet 6 opened on the left side of the upper end of the cover plate 5 facilitates the addition of lubricating oil to the inside of the reducer housing 1.

[0033] The connecting plate 3 is movably installed on the lower right side of the reducer housing 1, and a blocking plate 4 is fixedly installed on the left end of the connecting plate 3. A connecting rod 14 is movably installed on the outer side of the middle part of the connecting plate 3. A fixing block 15 is fixedly installed on the outer side of the rear end of the reducer housing 1, and a fixing rod 10 is movably connected to the outer side of the fixing block 15. The connecting shaft 16 is fixedly installed on the right side of the rear end of the reduction gear set 2, and a connecting rod 17 is movably connected to the outer side of the middle part of the connecting shaft 16. A monorail drive shaft 18 is movably installed on the inner side of the connecting rod 17. Rotating the connecting rod 14 connects the connecting rod 14 to the outer side of the left end of the connecting plate 3, thereby causing the connecting rod 14 to slide outward at the left end of the connecting plate 3, and then separate the connecting rod 14 from the outer side of the right end of the reducer housing 1, and then move to the right. Pull the connecting plate 3 to the side, causing the connecting plate 3 to separate the blocking plate 4 from the lower right side of the reducer housing 1, facilitating the removal of lubricating oil inside the reducer housing 1. Place the reducer housing 1 in front of the monorail, causing the reducer housing 1 to move the fixing block 15 to fit against the front of the monorail, thereby causing the reduction gear set 2 to drive the connecting shaft 16 to be installed on the outer front end of the monorail drive shaft 18. Rotate the connecting rod 17 to connect the connecting rod 17 to the outer middle part of the connecting shaft 16, thereby connecting the connecting rod 17 to the outer front end of the monorail drive shaft 18. Rotate the fixing rod 10 to connect the fixing rod 10 to the outer rear end of the fixing block 15, thereby connecting the fixing rod 10 to the housing of the monorail, facilitating the installation of the reducer housing 1.

[0034] When using a speed reducer for a monorail, specifically as follows: Figure 1 , Figure 3 and Figure 4 In this configuration, the reducer housing 1 is placed on the front side of the monorail crane. The monorail crane drive shaft 18 and the connecting shaft 16 are connected by a snap-fit ​​mechanism, causing the reducer housing 1 to drive the fixing block 15 to fit against the front side of the monorail crane. This causes the reduction gear set 2 to drive the connecting shaft 16 to snap-fit ​​onto the outer front end of the monorail crane drive shaft 18. The connecting rod 17 is rotated to make the connecting rod 17 threaded on the outer side of the middle part of the connecting shaft 16, thus making the connecting rod 17 threaded on the outer front end of the monorail crane drive shaft 18. The fixing rods 10 are symmetrically distributed about the center line of the fixing block 15. The fixing rods 10 are rotated to make the fixing rods 10 threaded on the outer rear end of the fixing block 15, thus making the fixing rods 10 threaded on the housing of the monorail crane, which facilitates the installation of the reducer housing 1.

[0035] Specific examples Figure 1 , Figure 5 and Figure 6In the reducer housing 1, the heat dissipation hole 7 on the upper middle side facilitates heat dissipation inside the reducer housing 1. The oil inlet 6 on the upper left side of the cover plate 5 facilitates the addition of lubricating oil inside the reducer housing 1. The connecting plate 3 and the connecting rod 14 are connected by threads, and the connecting rod 14 is symmetrically distributed about the center line of the connecting plate 3. Rotating the connecting rod 14 causes the connecting rod 14 to be threaded on the outer left side of the connecting plate 3, thereby causing the connecting rod 14 to slide outward on the left side of the connecting plate 3, and then separating the connecting rod 14 from the outer right side of the reducer housing 1. The connecting plate 3 and the reducer housing 1 are connected by a snap-fit ​​method, and the cross-sectional shape of the connecting plate 3 is a "U" shape. Pulling the connecting plate 3 to the right causes the connecting plate 3 to drive the blocking plate 4 to separate on the lower right side of the reducer housing 1, which facilitates the removal of lubricating oil inside the reducer housing 1.

[0036] Specific examples Figure 1 and Figure 2 In the process of rotating the mounting rod 13, the movable block 9 is connected to the mounting rod 13 by a thread and fixes the cover plate 5. The mounting rod 13 is threaded on the outer side of the upper end of the movable block 9, so that the mounting rod 13 slides outward on the upper end of the movable block 9, and then separates the mounting rod 13 from the outer side of the middle part of the cover plate 5. The movable block 9 is connected to the cover plate 5 by a sliding method, and the vertical cross-section of the movable block 9 is a "T" shape. Pulling the movable block 9 outward causes the movable block 9 to drive the spring 11 to extend, so that the movable block 9 slides outward on the outer side of the lower end of the cover plate 5, and then separates the movable block 9 from the outer side of the upper end of the reducer housing 1. Pulling the cover plate 5 upward causes the cover plate 5 to drive the connecting block 12 to separate on the upper side of the reducer housing 1, which facilitates the maintenance of the inside of the reducer housing 1.
