[0002] With the rapid development of urbanization, the subway has become an important public transportation tool in the urban rail transit system. Subway inspection and maintenance are indispensable to the subway system. The fixed car-lifting unit is one of the important equipment for subway vehicle inspection and maintenance. It can complete the lifting and lowering of the subway vehicle body and bogie, and realize the inspection and replacement of the vehicle bogie, the electrical cabinet at the bottom of the vehicle, etc. As an important component for the lifting and lowering function of the fixed car-lifting unit, the screw transmission mechanism will wear out due to long-term load-bearing operations, affecting the transmission efficiency and service life. Regular lubrication inspection and maintenance are essential. At present, most lubrication methods are manual regular lubrication and maintenance, which cannot achieve continuous lubrication effects. During long-term use, it is easy to cause problems such as partial lubrication failure, dirt adhesion, and reduced service life. Summary of the invention

[0005] The oil outlet hole at the bottom of the storage tank is provided with an inclined steel ball channel, and the steel ball is the switch of the oil outlet hole at the bottom of the storage tank. When the lead screw rotates, the storage tank is synchronously driven to rotate. Under the action of centrifugal force, the steel ball rolls into the steel ball channel at the bottom of the storage tank, and the oil outlet hole is opened; conversely, the lead screw stops rotating, the steel ball resets in the inclined steel ball channel, and the oil outlet hole is closed.

[0006] The plug is provided with a vent hole and is installed in the oil filling hole on the top of the storage tank to ensure the balance of air pressure inside the storage tank.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 7 As shown, the utility model provides a fixed crane lead screw self-lubricating device, including a storage tank 1 for storing lubricating liquid, the storage tank 1 is composed of two semi-annular tank bodies spliced ​​by a buckle 6, an oil filling hole 11 is provided on the top of the storage tank 1, the oil filling hole 11 is blocked by a plug 2, an oil outlet hole 12 is provided at the bottom of the storage tank 1, the oil outlet hole 12 cooperates with a steel ball 3 to realize the switch of the oil outlet hole 12, a fixing ring 4 is installed at the bottom of the oil outlet hole 12, and a brush 5 is installed outside the oil outlet hole 12 at the bottom of the storage tank 1.

[0022] The oil outlet hole 12 at the bottom of the storage tank 1 is provided with an inclined steel ball channel 13, and the steel ball 3 is the switch of the oil outlet hole 12 at the bottom of the storage tank 1. When the lead screw rotates, the storage tank 1 is synchronously driven to rotate. Under the action of centrifugal force, the steel ball 3 rolls into the steel ball channel 13 at the bottom of the storage tank 1, and the oil outlet hole 12 is opened; conversely, the lead screw stops rotating, the steel ball 3 is reset in the inclined steel ball channel 13, and the oil outlet hole 12 is closed.

[0023] The plug 2 is installed in the oil filling hole 11 on the top of the storage tank 1. A vent hole 21 is opened on the plug 2 to ensure that the air pressure inside the storage tank 1 is balanced and the lubricating liquid can flow out normally.

[0024] The fixing ring 4 is fixedly installed at the bottom of the storage tank 1 to support the steel ball 3 in the oil outlet hole 12 .

[0025] The brush 5 is in contact with the lead screw, and the lubricating liquid is applied to the surface of the lead screw through the brush 5 .

[0026] There are two buckles 6, which are fixed on two semi-annular tank bodies respectively, so as to realize the splicing and matching of the two semi-annular tank bodies and combine them into a storage tank 1.

[0027] The bottom of the storage tank 1 is a curved surface, which ensures that the lubricating liquid stored inside is used without residue.

[0028] When the device is in operation, the oil outlet 12 at the bottom of the tank 1 has two working states: one is a closed state: the tank 1 is fixed on the lead screw in a stationary state, and the top oil filling hole 11 is filled with lubricating liquid and then blocked with a plug 2. At this time, the oil outlet 12 at the bottom of the tank 1 is blocked by the steel ball 3 and is in a closed state. The lubricating liquid in the tank 1 cannot flow out. Before the lead screw device is not activated, the bottom oil outlet 12 is always in a closed state. Figure 6 The first is the position of the steel ball 3-1; the second is the open and closed state: the storage tank 1 is fixed on the screw in a rotating state. At this time, the storage tank 1 rotates with the screw. The steel ball 3 at the bottom rolls away from the bottom oil outlet 12 under the action of inertia and rolls into the steel ball channel 13. The lubricant in the storage tank 1 flows out and is applied to the surface of the screw under the guidance of the brush 5 to complete the lubrication. According to the rotation speed of the screw, the steel ball 3 at the bottom will be in different positions, and the bottom oil outlet 12 will have different degrees of opening and closing, thereby determining the different flow rates of the lubricant flowing out of the storage tank 1, such as Figure 6 The middle steel balls 3-2 and 3-3 are in different positions. After the lead screw stops rotating, the oil outlet hole 12 at the bottom of the storage tank 1 returns to the closed state.

[0029] The utility model comprises two semi-annular tank bodies which are fastened to form a storage tank to hold a lead screw, wherein lubricating liquid is stored in the storage tank and rotates together with the lead screw, so that the lubricating liquid flows out of the storage tank to lubricate the lead screw, which is beneficial to continuously lubricate the lead screw, prevents wear problems, and reduces manual work.

[0030] The utility model has a simple structure, solves the problem that the lead screw of the fixed frame lathe machine is not covered with lubrication during operation, resulting in wear of the lead screw, ensures the continuous lubrication effect of the lead screw, reduces manual work, and improves production efficiency.

[0031] The above embodiments of the present invention are merely illustrative and not exclusive, and all modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
