Description

Technical Field

[0001] This utility model relates to the field of power faucet technology, and in particular to a hydraulic top-operating power faucet device. Background Technology

[0002] A power swivel is a type of mechanical device commonly used in oil drilling operations. It provides rotational power while its unique central tube structure allows for fluid flow. The power swivel primarily uses a hydraulic motor or electric motor as its power source, which is transmitted to the central tube via a reducer, ensuring sufficient power and torque.

[0003] In existing technologies, power is transmitted through a simple connection between the power source, reducer, and central tube. These components are relatively independent of each other, resulting in a heavy overall structure. Furthermore, the torque is concentrated during the power transmission process, which affects the upper limit of torque transmission. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic top-operated power faucet device, which simplifies the internal structure, optimizes the power transmission process, avoids torque concentration during transmission, and increases the upper limit of the overall structure's torque bearing capacity.

[0005] This utility model provides a hydraulic top-operated power faucet device, comprising:

[0006] A hydraulic motor, comprising a turntable, wherein hydraulic oil is supplied to the hydraulic motor and the hydraulic oil pressure drives the turntable to rotate, and the hydraulic motor has a hollow structure;

[0007] The reducer assembly includes a sun gear, planet gears, a planet carrier, and an internal gear ring. The sun gear is a hollow gear integrally formed on the turntable, and power is transmitted from the sun gear to the planet carrier.

[0008] A central tube passes through the hydraulic motor and the reducer assembly, and is fixedly connected to the planetary carrier.

[0009] Preferably, the hydraulic motor further includes a housing, a distribution block, a plunger, a contact block, and a swashplate. The distribution block is fixedly assembled inside the housing, and the turntable is rotatably assembled inside the housing. The turntable has plunger holes distributed circumferentially. The plunger is slidably assembled in the plunger holes on the turntable in the radial direction. The two ends of the contact block abut against the plunger and the swashplate, respectively.

[0010] Preferably, the hydraulic motor further includes a spring, one end of which abuts against the inner wall of the housing and the other end of which abuts against the distribution block, the spring force pressing the distribution block tightly against the turntable.

[0011] Preferably, the hydraulic motor further includes a wear-resistant block located between the distribution block and the turntable.

[0012] Preferably, the reducer assembly is assembled inside the housing.

[0013] Preferably, the internal gear ring is integrally formed on the inner wall of the housing.

[0014] Preferably, the planetary carrier is integrally formed on the outer wall of the central tube.

[0015] Preferably, the outer wall of the central tube is stepped shaft-shaped, and a bearing assembly is fitted on the central tube. The central tube is rotatably assembled at the center of the housing through the bearing assembly.

[0016] Preferably, the bearing assembly includes a thrust bearing, a radial bearing, and an angular contact bearing. The thrust bearing is located between the central tube and the bottom plate of the housing, the radial bearing is located between the central tube and the turntable, and the angular contact bearing is located between the central tube and the top plate of the housing.

[0017] Preferably, reinforcing ribs are integrally formed on the outer wall of the shell bottom plate.

[0018] The technical solution of this utility model uses a hydraulic motor as a power source, directly combining the turntable driven by the hydraulic oil in the hydraulic motor with the sun gear, the power input element of the reducer assembly, thus omitting the conventional transmission structure between the two and making the overall structure more compact. At the same time, it avoids the problem of torque concentration during the transmission from the hydraulic motor to the reducer assembly due to the reduction in axial dimension caused by setting a transmission structure. Furthermore, the overall transmission process adopts a multi-gear synchronous torque transmission method, avoiding torque concentration on a single gear and increasing the upper limit of the torque that the overall structure can withstand.

[0033] Combination Figures 1 to 6 As shown, the hydraulic top-operated power faucet device provided by this utility model includes a hydraulic motor 1, a reducer assembly 2, and a central tube 3.

[0034] Combination Figures 1 to 6 As shown, the hydraulic motor 1 mainly includes a housing 11, a distribution block 12, a turntable 15, a plunger 16, a contact block 17, and a swashplate 18. The distribution block 12 is fixedly mounted inside the housing 11, and the turntable 15 is rotatably mounted inside the housing 11. One end of a spring 110 abuts against the inner wall of the housing 11, and the other end of the spring 110 abuts against the distribution block 12. The elastic force of the spring 110 presses the distribution block 12 tightly against the turntable 15. Wear-resistant blocks 13 are mounted on both the distribution block 12 and the turntable 15, and the wear-resistant blocks 13 rub against each other between the distribution block 12 and the turntable 15. The turntable 15 has plunger holes distributed circumferentially, and the plunger 16 is slidably mounted in the plunger holes on the turntable 15 in the radial direction. The two ends of the contact block 17 abut against the plunger 16 and the swashplate 18, respectively. The hydraulic motor 1 has an overall annular hollow structure.

[0035] Hydraulic oil is introduced into the hydraulic motor 1. The hydraulic oil passes through the housing 11 and enters the plunger hole of the turntable 15 through the distributor block 12. The hydraulic oil pressure drives the plunger 16 in the plunger hole of the turntable 15 to slide. The plunger 16 cooperates with the contact block 17 to convert the linear motion of the plunger 16 into the rotational motion of the turntable 15, so that the hydraulic oil pressure drives the turntable 15 to rotate.

[0036] The reducer assembly 2 is assembled inside the housing 11. The reducer assembly 2 includes a sun gear 21, planet gears 22, a planet carrier 23, and an internal gear ring 24. The sun gear 21 is a hollow gear and is integrally formed on the turntable 15. The planet carrier 23 is fixedly connected to the central tube 3. The planet gears 22 are rotatably mounted on the planet carrier 23. The internal gear ring 24 is integrally formed on the inner wall of the housing 11. The sun gear 21, planet gears 22, and internal gear ring 24 mesh in sequence. Power is transmitted from the sun gear 21 to the planet carrier 23 and finally to the central tube 3.

[0037] The sun gear 21 is the driving structure, and the planet carrier 23 is the output structure, which achieves the driving effect of reducing speed and increasing torque.

[0038] The central tube 3 passes through the hydraulic motor 1 and the reducer assembly 2. The outer wall of the central tube 3 is stepped shaft-shaped. The planetary carrier 23 is integrally formed on the outer wall of the central tube 3 to achieve a fixed connection between the two. A bearing assembly is fitted on the central tube 3. The bearing assembly includes a thrust bearing 31, a radial bearing 32 and an angular contact bearing 33. The thrust bearing 31 is located between the central tube 3 and the bottom plate of the housing 11. The outer wall of the bottom plate of the housing 11 is integrally formed with reinforcing ribs to enhance its structural strength. The radial bearing 32 is located between the central tube 3 and the turntable 15. The angular contact bearing 33 is located between the central tube 3 and the top plate of the housing 11. The central tube 3 is rotatably assembled at the center of the housing 11 through the bearing assembly.

[0039] By using a bearing assembly with multiple bearing combinations to rotate the central tube 3, the fixing and support effect of the central tube 3 can be enhanced, and the ability of the central tube 3 to withstand radial and axial loads can be improved.

[0040] Working process: Hydraulic oil is introduced into the hydraulic motor 1 to drive the turntable 15 to rotate. The sun gear 21, as the drive structure of the reducer assembly 2, is integrally formed on the turntable 15, transmitting power into the reducer assembly 2. The output structure of the reducer assembly 2, the planetary carrier 23, is integrally formed on the central tube 3, ultimately transmitting power to the central tube 3.

[0041] In this embodiment, the hydraulic motor 1 is used as the power source, and the turntable 15 directly driven by the hydraulic oil in the hydraulic motor 1 and the sun gear 21, the power input element of the reducer assembly 2, are directly combined, omitting the conventional transmission structure between the two, making the overall structure more compact; at the same time, it avoids the problem of torque concentration during the transmission from the hydraulic motor 1 to the reducer assembly 2 due to the reduction of axial dimension caused by setting a transmission structure. In addition, the overall transmission process adopts a multi-gear synchronous torque transmission method, which avoids the torque concentration on a single gear and increases the upper limit of the torque that the overall structure can withstand.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
