Description
Technical Field
[0001] The utility model relates to the technical field of reducers for hoists, in particular to a reducer for cement hoists. Background Art
[0002] Cement is a common building material. It is a powdery substance made mainly from minerals such as lime, silicate, ferrite and aluminate through calcination and grinding. Cement plays an important role in construction projects and is used to make building materials such as concrete, mortar, and mortar, as well as being used as an adhesive for building structures. Cement often needs to be lifted, conveyed and loaded and unloaded during production, transportation and construction, and cement hoists are important equipment for achieving these tasks. Cement hoists need to overcome gravity and friction to lift cement or other materials. Electric motors usually have the characteristics of high speed and low torque, while cement hoists require low speed and high torque output. The role of the reducer is to convert the high speed and low torque output of the motor into the low speed and high torque output required by the hoist to ensure that the hoist can effectively lift the material.
[0003] The reducer for traditional elevators is a mechanical transmission device that can reduce the output speed of a high-speed rotating motor and transmit sufficient torque to drive the lifting and lowering movement of the elevator to ensure that the elevator can stably lift or lower cement. By properly selecting the reduction ratio of the reducer, the appropriate speed of the elevator can be achieved to meet the lifting needs of cement under different working conditions.
[0004] However, traditional reducers for hoists usually use traditional threaded installation and usually rely on threaded connections to fix the hoist without additional internal support structures. This may limit the stability of the hoist during operation, especially when the load is large or the height is high. Therefore, a reducer for a cement hoist is proposed to solve the above problems.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a reducer for a cement hoist, including a reduction device 5, a base 2 is fixedly connected to the bottom of the reduction device 5, a fixed seat 1 is arranged at the bottom of the base 2, a fixed disc 11 is fixedly connected inside the base 2, a screw rod 10 is threadedly connected inside the fixed disc 11, a knob 7 is fixedly connected to the top of the screw rod 10, a fixed column 12 is threadedly connected to the outer wall of the screw rod 10, the top of the fixed column 12 is fixedly connected to the bottom of the fixed disc 11, a rotating rod 13 is rotatably connected to the outer wall of the fixed column 12, a fixture 9 is rotatably connected to one side of the outer wall of the rotating rod 13, a transmission rod 14 is rotatably connected to the outer wall of the fixture 9, a connecting disc 15 is rotatably connected to the outer wall of the transmission rod 14, the connecting disc 15 is rotatably connected to the outer wall of the screw rod 10, the outer wall of the fixture 9 is arranged inside the fixed seat 1, and a lubrication component is arranged inside the reduction device 5.
[0032] Specifically, the knob 7 is turned to drive the screw rod 10 to rotate through the knob 7, and then the screw rod 10 drives the connecting disc 15 to rise and fall, and then the connecting disc 15 drives the transmission rod 14 to move, and at the same time, the fixing device 9 drives the rotating rod 13 to rotate, so that the device is fixed on the top of the fixing seat 1, which can distribute the force more evenly and reduce the vibration and noise of the equipment during operation. This not only improves the working efficiency of the equipment, but also reduces the impact on the surrounding environment and operators, and makes it easier to maintain and maintain the equipment, because the support structure is more centralized and easy to access, which makes it easier for maintenance personnel to inspect, clean and repair, thereby reducing the time and cost during the maintenance process. At the same time, it can be hidden inside the equipment, making the appearance of the equipment more beautiful and simple.
[0033] Reference Figure 1 The lubrication assembly includes a refueling port 4 and an oil drain hole 8 . The outer wall of the refueling port 4 is arranged inside the reduction gear 5 , and the outer wall of the oil drain hole 8 is arranged inside the reduction gear 5 .
[0034] Specifically, the oil filling port 4 is used to inject lubricating oil or grease into the reducer 5. By injecting a proper amount of lubricant, the lubrication state of the equipment can be maintained, friction and wear can be reduced, and the service life of the equipment can be extended. It is located on the external surface of the equipment, which is convenient for operators to perform lubrication maintenance regularly. At the same time, the oil drain hole 8 is used to drain the reducer 5. When the lubricating oil or grease deteriorates or is contaminated during use, it needs to be discharged in time to keep the lubrication system clean and operate normally. It is located at the bottom of the equipment to facilitate the outflow of lubricating oil or contaminants.
[0035] Reference Figure 1 and Figure 3 A main shaft 3 is arranged inside the reduction gear 5, and a rotating wheel 20 is slidably connected to the outer wall of the main shaft 3. A reverse blocking device 6 is arranged on the outer wall of the rotating wheel 20. A connecting piece 23 is fixedly connected to the outer wall of the reverse blocking device 6. The outer wall of the connecting piece 23 is fixedly connected to the outer wall of the fixing seat 1. A limiting groove 16 is opened inside the reverse blocking device 6. A sliding column 19 is slidably connected inside the reverse blocking device 6. A sliding column 19 is fixedly connected to one end of the sliding column 19. The sliding column 21 is slidably connected to the inside of the reverse blocking device 6. A limiting disc 17 is fixedly connected to one end of the sliding column 19. The outer wall of the limiting disc 17 is slidably connected to the inside of the limiting groove 16. A spring 18 is sleeved on the outer wall of the sliding column 19. One end of the spring 18 is fixedly connected to the sliding block 21. One end of the spring 18 is fixedly connected to the inner wall of the reverse blocking device 6. A sliding column 22 is fixedly connected to the outer wall of the sliding block 21. The outer wall of the sliding column 22 is slidably connected to the inside of the reverse blocking device 6.
[0036] Specifically, when the device rotates normally, it drives the wheel 20 to rotate. The rotating surface in contact with the slider 21 is an inclined surface and can be directly pushed to compress the spring 18, and then the spring 18 rebounds to bounce the device back to its original position. When the device reverses, it drives the wheel 20 to reverse. The contact surface with the slider 21 is a plane and cannot slide, so it is stuck to prevent reversal. It can protect the equipment and workpiece from damage caused by reversal. Especially in applications that require precise position control or protection of the workpiece surface from scratches and collisions, the use of anti-reversal devices is very important. During operation, the device may stop or lose power due to sudden factors. Without an anti-reversal device, the equipment may reverse due to inertia and other reasons, resulting in unpredictable movement and risks. The use of an anti-reversal device 6 can avoid such unexpected movement.
[0037] Working principle: place the base 2 on the top of the fixed seat 1, then turn the knob 7, and drive the fixedly connected screw rod 10 to rotate inside the fixed column 12 to which it is threaded, and then drive the rotatably connected connecting disc 15 to rise and fall through the screw rod 10, and then drive the rotatably connected transmission rod 14 to rotate through the connecting disc 15, and then drive the rotatably connected fixture 9 to move through the transmission rod 14, and at the same time drive the rotatably connected rotating rod 13 to rotate on the outer wall of the fixed column 12 to which it is rotatably connected through the fixture 9, so as to fix the device, and then start the device, and drive the slidingly connected rotating wheel 20 to rotate through the main shaft 3, and then push the slider 21 to slide inside the slidingly connected anti-reversal device 6 through the rotating wheel 20, and at the same time push the fixedly connected spring 18 to be compressed through the slider 21, and then rebound through the spring 18 between the two, driving the fixedly connected slider 21 back to its original position, and then if the device is reversed, then drive the rotating wheel 20 to reverse through the main shaft 3, and then because the reversing surface is a plane, it is stuck and cannot be reversed, and at the same time, the lubricating oil can be added and discharged through the oil filling port 4 and the oil drain hole 8.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
