Description

Technical Field

[0001] This utility model relates to the field of valve sealing technology, and in particular to a novel gear rack and pinion slide valve drive frequency conversion setting. Background Technology

[0002] A search revealed patent number CN202122214243.3, which describes a novel gear and rack drive mechanism for a flue gas duct slide valve. The mechanism includes a slide valve frame with racks on both sides. Each rack has a drive gear, and a rotating shaft connects the two drive gears. A reducer is located in the center of the rotating shaft, and a power motor is mounted on the reducer. The power motor serves as the power source, and the reducer lowers the rotational speed while increasing the torque of the output shaft. This drives the drive gears mounted on the output shafts on both sides of the reducer. The drive gears mesh with the racks on both sides of the slide valve frame. The forward and reverse rotation of the drive gears opens or closes the slide valve, ensuring the synchronicity of the slide valve's vertical movement and preventing jamming, vibration, and abnormal noise caused by asynchronous movement. The slide valve utilizes a rack and gear drive mechanism to achieve smoother and more stable opening and closing of the flue gas duct slide valve.

[0003] The aforementioned patents still have the following problems in practical use:

[0004] The start-stop impact is large. When the constant speed motor is started directly, the torque changes suddenly, which causes gear and rack meshing impact and valve plate to hit the valve seat quickly. Long-term use can easily cause wear on gear tooth surface, deformation of valve plate, aging and leakage of seals, and high equipment maintenance costs.

[0005] Insufficient lubrication: Long-term use and exposure of the rack and gear can lead to a large amount of dust accumulating at the meshing parts, affecting the smoothness of subsequent transmission.

[0006] Therefore, we propose a novel gear rack and pinion valve drive frequency conversion setting. Utility Model Content

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0008] This utility model provides a novel gear and rack slide valve drive frequency conversion setting, which can solve the problem of insufficient lubrication at the transmission components. The specific solution is as follows:

[0009] A novel gear and rack slide valve drive frequency converter includes a frame, with a slide valve body movably connected inside the frame. An outer casing is connected to the outer wall of the frame, and a drive structure is disposed inside the outer casing. The drive structure is interconnected with the slide valve body, driving the slide valve body to perform repetitive radial motion in the middle of the frame. A control frequency converter is fixedly connected to the outer side of the outer casing, and a speed reducer is connected to the other side of the outer casing. The output end of the speed reducer is interconnected with the drive structure, and the speed reducer and the control frequency converter are electrically connected. A lubrication structure is disposed at the top of the outer casing.

[0010] In a preferred embodiment of this invention, the lubrication structure includes a bracket mounted on the top of the outer casing. A storage tank is fixedly connected to the middle of the bracket, and the storage tank contains liquid lubricating oil. A lifting frame is connected to the outer side of the storage tank. The bottom end of the lifting frame is fixedly connected to the bracket.

[0011] As a preferred embodiment of this utility model, the end of the storage box is fixedly connected to a nozzle, the nozzle has a bent structure, and one end of the nozzle extends through the outer casing to the top of the drive structure, and the middle of the nozzle is fixedly connected to an oil pump.

[0012] As a preferred technical solution of this utility model, the driving structure includes a gear and a rack. The rack is disposed on the side wall of the frame, and one end of the rack is fixedly connected to the side wall of the plate valve body. The gear and the rack are meshed with each other.

[0013] In a preferred embodiment of this invention, the central axis of the rack is fixedly connected to a transmission rod, the position of which corresponds to the position of the reducer, and the transmission rod is connected to the output end of the reducer.

[0014] As a preferred embodiment of this utility model, a sliding groove is also provided on the side wall of the frame, and a slider is fixedly connected to the inner side of the rack. The slider is embedded in the sliding groove, and the slider and the sliding groove are slidably connected to each other.

[0015] As a preferred technical solution of this utility model, the end of the frame is fixedly connected to a positioning plate, the positioning plate is provided with two sets of positioning grooves, the two sides of the plate valve body are connected to sealing strips, and the top two sides of one end of the plate valve body are connected to positioning pins, the positions of the positioning pins and the positioning grooves correspond to each other.

[0016] As a preferred embodiment of this utility model, a through hole is provided at the end of the outer casing, which allows the rack to move radially.

[0017] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0018] By setting up an outer casing, on which a control frequency converter is connected, and this control frequency converter is electrically connected to the reducer, the opening speed of the reducer can be reasonably controlled, so that the gears and racks can achieve transmission more precisely and uniformly, driving the plate valve body to complete the movement;

[0019] The outer casing covers the rack and gear structure, preventing dust from directly entering between them, thus preventing dust and impurities from entering and reducing meshing wear. By setting up a lubrication structure, drip lubrication continuously delivers lubricating oil to the meshing tooth surfaces, forming a uniform oil film that completely isolates the metal contact surfaces of the gear and rack, avoiding dry friction or boundary friction. Continuous dripping oil can also remove dust and impurities in the meshing gap, preventing jamming caused by abrasive accumulation.

[0020] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0029] See Figures 1-4 This utility model provides a novel gear and rack slide valve drive frequency conversion device, including a frame 1, a slide valve body 2 movably connected inside the frame 1, an outer shell 6 connected to the outer wall of the frame 1, a drive structure inside the outer shell 6, the drive structure being interconnected with the slide valve body 2, driving the slide valve body 2 to form repeated radial motion in the middle of the frame 1; a control frequency converter 7 is fixedly connected to the outer side of the outer shell 6, a reducer 8 is connected to the other side of the outer shell 6, the output end of the reducer 8 is interconnected with the drive structure, the reducer 8 and the control frequency converter 7 are electrically connected to each other, and a lubrication structure is provided at the top of the outer shell 6.

[0030] The lubrication structure includes a bracket 9 mounted on the top of the outer casing 6, a storage tank 10 fixedly connected to the middle of the bracket 9, the storage tank 10 containing liquid lubricating oil, and a lifting frame connected to the outside of the storage tank 10. The bottom end of the lifting frame is fixedly connected to the bracket 9.

[0031] By setting up an outer casing 6, and connecting a control frequency converter 7 on the outer casing 6, the control frequency converter 7 is electrically connected to the reducer 8, which can reasonably control the opening speed of the reducer 8, so that the gear 17 and the rack 16 can achieve transmission more precisely and uniformly, driving the plate valve body to complete the movement.

[0032] The outer casing 6 encloses the rack 16 and gear 17 structure, preventing dust from directly entering between them, preventing dust and impurities from entering, reducing meshing wear, and by setting a lubrication structure, drip lubrication continuously delivers lubricating oil to the meshing tooth surface to form a uniform oil film, completely isolating the metal contact surface of the gear and rack, avoiding dry friction or boundary friction. Continuous dripping oil can carry away dust and impurities in the meshing gap, preventing jamming caused by abrasive accumulation.

[0033] The end of the storage box 10 is fixedly connected to the nozzle 12, which has a bent structure. One end of the nozzle 12 extends through the outer casing 6 to the top of the drive structure, and the middle of the nozzle 12 is fixedly connected to the oil pump 11.

[0034] The drive structure includes a gear 17 and a rack 16. The rack 16 is disposed on the side wall of the frame 1, and one end of the rack 16 is fixedly connected to the side wall of the plate valve body 2. The gear 17 and the rack 16 are meshed with each other.

[0035] The central axis of the rack 16 is fixedly connected to the transmission rod 18. The position of the transmission rod 18 corresponds to the position of the reducer 8, and the transmission rod 18 is connected to the output end of the reducer 8. By starting the reducer 8, the gear 17 is driven to rotate. Since the gear 17 and the rack 16 mesh with each other, the rack 16 will be driven to move laterally. At this time, the rack 16 drives the plate valve body 2 to complete the lateral movement, thereby realizing the closure of the valve.

[0036] A slide groove 15 is also provided on the side wall of the frame 1. A slider 14 is fixedly connected to the inner side of the rack 16. The slider 14 is embedded in the slide groove 15, and the slider 14 and the slide groove 15 are slidably connected to each other. As the rack 16 moves, the slider 14 slides inside the slide groove 15, providing a limiting effect for the rack 16 while also having a certain degree of stability.

[0037] The end of the frame 1 is fixedly connected to the positioning plate 3. Two sets of positioning grooves are opened on the positioning plate 3. The two sides of the plate valve body 2 are connected to the sealing strip 5. The top of one end of the plate valve body 2 is connected to the positioning pin 4 on both sides. The positions of the positioning pin 4 and the positioning groove correspond to each other.

[0038] The end of the outer casing 6 has a through hole 13, which allows the rack 16 to move radially. By providing the through hole 13, the movement of the rack 16 is not obstructed.
