Description

Technical Field

[0001] The utility model relates to the technical field of electric hoist reducers, in particular to an energy-saving electric hoist reducer. Background Art

[0002] With the continuous progress of information technology and the rapid development of the national economy, frequency conversion technology has been widely used in the field of power supply due to its advantages such as wide speed regulation range, high transmission efficiency and significant power saving. It is a key energy-saving project promoted by the state. The existing electric hoists in China, especially simple and cheap electric hoists, are widely used in general objects due to their simple structure. They can be raised and lowered under various height differences. However, if they are used to raise and lower precision instruments, they are not competent because of their excessive speed. If reducers and pulleys are added, the volume will increase and the cost will increase dramatically.

[0003] When the electric hoist reducer is in use, the lifting and lowering of the object is generally completed by rotating the gears and gear ratios. However, during the long-term use of the gears and gear ratios, the lubrication between the gears and gear ratios will be reduced and the friction will increase, which will increase the energy consumption of the device to a certain extent.

[0023] Embodiment 1:

[0024] The present application provides an energy-saving electric hoist reducer, comprising a reducer body 1; a placement groove 4 is provided on the top of the reducer body 1, and a refueling mechanism 6 is installed inside the placement groove 4;

[0025] The refueling mechanism 6 includes an oil tank 601, an oil inlet 602, an oil outlet pipe 603 and a metering valve 604. The oil tank 601 is fixedly installed on the top of the reducer body 1. The top of the oil tank 601 is provided with an oil inlet 602. The bottom of the oil tank 601 is provided with an oil outlet pipe 603 inserted into the inner cavity of the placement groove 4. The surface of the oil outlet pipe 603 is fixedly installed with a metering valve 604. The outer side of the oil outlet pipe 603 is fixedly installed with a limit block 7. The electric hoist body 2 is fixedly installed on one side of the reducer body 1 by bolts, and a vacuum chamber 3 is provided in the inner cavity of the reducer body 1.

[0026] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when personnel install the reducer body 1 to the output end of the electric hoist body 2 and fix it, when the gears and gear ratios inside the reducer body 1 rotate internally, personnel add lubricating oil to the inside of the oil tank 601 through the oil inlet 602. During use, the lubricating oil is added to the surface of the gears and gear ratios inside the reducer body 1 through the oil outlet pipe 603 through the metering valve 604, which can reduce the friction of the gears and gear ratios, thereby further reducing the increase in torque caused by the friction of the gears and gear ratios, thereby further saving energy and improving the rotation efficiency.

[0027] Further, the reducer body 1 is symmetrically provided with a mounting block 5, and a fixing mechanism 8 is symmetrically provided on the inner side of the mounting block 5. The fixing mechanism 8 includes a placement cavity 801, a spring 802 and a clamping block 803. The placement cavity 801 is opened in the inner cavity of the mounting block 5, and a spring 802 is installed inside the placement cavity 801. A clamping block 803 is slidably installed on one side of the spring 802. A clamping groove 9 is opened on the outer side of the oil tank 601.

[0028] Specifically, Figure 1 , Figure 2 As shown, when the device is in use, the personnel installs the refueling mechanism 6 to the inner side of the mounting block 5, and then pulls the card block 803 outward so that the card block 803 is located in the inner cavity of the placement cavity 801, and then places the refueling mechanism 6 on the surface of the reducer body 1, and the oil outlet pipe 603 is inserted into the inner cavity of the placement groove 4, and then the slot 9 is made to correspond to the card block 803, and then the card block 803 is released, and the card block 803 will bounce into the inside of the slot 9 under the elastic force of its internal spring 802, so that the refueling mechanism 6 can be quickly installed on the surface of the reducer body 1 for use.

[0029] Working principle: When the refueling mechanism 6 is installed to the inner side of the mounting block 5, the personnel pulls the block 803 outward so that the block 803 is located in the inner cavity of the placement cavity 801, and then places the refueling mechanism 6 on the surface of the reducer body 1, and the oil outlet pipe 603 is inserted into the inner cavity of the placement groove 4, and then the groove 9 is made to correspond to the block 803, and then the block 803 is released. The block 803 will bounce into the inside of the groove 9 under the elastic force of its internal spring 802. When the gears and gear ratios inside the reducer body 1 rotate internally, the personnel add lubricating oil to the inside of the oil tank 601 through the oil inlet 602. During use, the lubricating oil is added to the surface of the gears and gear ratios inside the reducer body 1 through the oil outlet pipe 603 through the metering valve 604, which can reduce the friction of the gears and gear ratios.

[0030] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it.
