Description

Technical Field

[0001] This utility model relates to the field of hydraulic unit maintenance technology, specifically a support device for the maintenance of a rotary guide hydraulic unit. Background Technology

[0002] The primary function of seals in a hydraulic system is to prevent fluid leakage and ensure the system's tightness. Due to prolonged use, hydraulic units often require seal replacement, necessitating the use of mounting supports to secure these seals.

[0003] For example, announcement number CN205799356U, entitled "A Sealing Ring Installation Device," includes a frustum and a cylinder coaxially arranged. The large-diameter end of the frustum is fixedly connected to the lower end of the cylinder to form a sealing ring assembly structure. The diameter of the small-diameter end of the frustum is smaller than the inner diameter of the sealing ring. The diameter of the large-diameter end of the frustum is equal to the diameter of the cylinder. The diameter of the cylinder is equal to the diameter of the lower end face of the piston sealing rod. An insert block is added to the lower end of the piston sealing rod. The insert block is coaxially arranged with the piston sealing rod, and its diameter is smaller than the diameter of the lower end face of the piston sealing rod. A hole matching the shape of the insert block is opened on the upper end face of the sealing ring assembly structure. The sealing ring assembly structure is inserted and locked to the piston sealing rod by means of the cooperation of the hole and the insert block. This greatly avoids the occurrence of sealing ring damage or reduced lifespan due to excessive or improper force. It saves time and effort during installation, greatly reduces the installation difficulty, and has a simple structure and is easy to use.

[0004] The existing sealing ring installation device cannot ensure that the internal sealing ring is always in the sleeved state during use, which makes it difficult for the sealing ring to be sleeved on the outside when the hydraulic unit is inserted, affecting the installation effect. Therefore, it does not meet the existing requirements. To address this, a support device for maintenance of rotary guide hydraulic units is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a support device for the maintenance of a rotary guide hydraulic unit, so as to solve the problem mentioned in the background art that the existing sealing ring installation device cannot ensure that the internal sealing ring is always in the sleeve state during use, which makes it difficult to sleeve the sealing ring on the outside when the hydraulic unit is inserted, thus affecting the installation effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support device for maintenance of a rotary guide hydraulic unit, comprising: a sealing ring limiting member, a hydraulic unit limiting member installed above the sealing ring limiting member, an adjusting component installed between the sealing ring limiting member and the hydraulic unit limiting member, three sets of expansion support members installed on the upper surface of the adjusting component, and a driving component installed inside the adjusting component.

[0007] Preferably, the adjustment assembly includes an adjustment platform, the upper surface of which has three annularly spaced displacement grooves, both sides of which have limit guide grooves, the bottom of which has a lower opening, and a first insertion hole between the three displacement grooves.

[0008] Preferably, the drive assembly includes a turntable, which is installed inside an adjustment platform. The upper surface of the turntable has three sets of guide grooves. Two supports are installed on one side of the bottom of the adjustment platform, and a worm gear is installed between the supports. A worm wheel is provided at the bottom of the turntable, and a motor is installed at one end of the worm gear.

[0009] Preferably, the expansion support includes a slide block, with sliders on both sides of the slide block, a connecting rod at the lower end of the slide block, and a guide block at the lower end of the connecting rod, the guide block being located in a guide groove.

[0010] Preferably, an electric telescopic rod is installed inside the slide block, and an arc-shaped limiting plate is installed at the telescopic end of the electric telescopic rod.

[0011] Preferably, the hydraulic unit limiting member has a second insertion hole inside for the hydraulic unit rod, and the size of the second insertion hole is larger than that of the first insertion hole.

[0012] Preferably, a base is installed at the bottom of the sealing ring limiting member, and a through hole is provided on the outer wall of the sealing ring limiting member.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the slide is used to move within the displacement groove. The sealing ring to be assembled is supported and restricted by three sets of arc-shaped limiting plates. The arc structure can better fit the circular structure of the sealing ring. By adjusting the distance between the three slides, the expansion force of the arc-shaped limiting plate on the sealing ring is changed. After the hydraulic unit rod is inserted into the first insertion hole, the hydraulic unit rod will be inserted into the expanded sealing ring at the same time. The arc-shaped limiting plate moves to the bottom by retracting the electric telescopic rod downward. After the sealing ring is no longer restricted by the arc-shaped limiting plate, it retracts to the surface of the hydraulic unit, thereby achieving the effect of fitting the sealing ring onto the hydraulic unit.

[0015] (2) In this utility model, the worm is driven to rotate by the motor, and the worm drives the worm wheel and the turntable to rotate. Due to the rotation of the turntable, the guide groove is displaced, causing the guide block in the guide groove to move. Through the connection of the connecting rod, the upper slide block slides back and forth in the displacement groove. During the back and forth displacement, the slider moves in the limit guide groove, which improves the smoothness of the sliding at the slide block. After the slide block slides, the position of the slide block and the expansion support changes. Moving inward makes the expansion support closer to each other, causing the sealing ring to retract. Moving outward makes the sealing ring further supported and expanded, increasing the opening size of the sealing ring, which is convenient for subsequent mounting on the hydraulic unit.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-6This utility model provides an embodiment of a support device for the maintenance of a rotary guide hydraulic unit, comprising: a sealing ring limiting member 1, a hydraulic unit limiting member 5 mounted above the sealing ring limiting member 1, an adjusting assembly 2 installed between the sealing ring limiting member 1 and the hydraulic unit limiting member 5, three sets of expansion support members 3 mounted on the upper surface of the adjusting assembly 2, and a driving assembly 4 installed inside the adjusting assembly 2. The expansion support member 3 includes a slide 301, with sliders 306 on both sides of the slide 301, a connecting rod 304 at the lower end of the slide 301, a guide block 305 at the lower end of the connecting rod 304, the guide block 305 being located within a guide groove 406, an electric telescopic rod 302 installed inside the slide 301, and an arc-shaped limiting plate 303 mounted on the telescopic end of the electric telescopic rod 302; the slide 301 is used for displacement within a displacement groove 201, and the three sets of arc-shaped limiting plates 303 support and restrict the sealing ring to be assembled. The arc-shaped structure better fits the circular structure of the sealing ring. By adjusting the distance between the three sliding blocks 301, the expansion force of the arc-shaped limiting plate 303 on the sealing ring is changed. After the hydraulic unit rod is inserted into the first insertion hole 204, the hydraulic unit rod will simultaneously be inserted into the expanded sealing ring. The electric telescopic rod 302 retracts downward, causing the arc-shaped limiting plate 303 to move to the bottom. After the sealing ring is no longer restricted by the arc-shaped limiting plate 303, it resets and retracts to the surface of the hydraulic unit, thereby achieving the effect of fitting the sealing ring onto the hydraulic unit.

[0025] Please see Figure 4 , Figure 5 The adjustment assembly 2 includes an adjustment platform 205. The upper surface of the adjustment platform 205 is provided with three annularly spaced displacement grooves 201. Limit guide grooves 202 are provided on both sides inside the displacement grooves 201. The bottom of the displacement grooves 201 is provided with a lower opening 203. A first insertion hole 204 is provided between the three displacement grooves 201. The drive assembly 4 includes a turntable 405. The turntable 405 is installed inside the adjustment platform 205. The upper surface of the turntable 405 is provided with three sets of guide grooves 406. Two brackets 401 are installed on one side of the bottom of the adjustment platform 205. A worm gear 403 is installed between the brackets 401. A worm wheel 404 is provided at the bottom of the turntable 405. A motor 402 is installed at one end of the worm gear 403.

[0026] The motor 402 drives the worm gear 403 to rotate, which in turn drives the worm wheel 404 and the turntable 405 to rotate. Due to the rotation of the turntable 405, its guide groove 406 is displaced, causing the guide block 305 in the guide groove 406 to move. Through the connection of the connecting rod 304, the upper slide block 301 slides back and forth in the displacement groove 201. During the back and forth movement, the slider 306 moves in the limiting guide groove 202, which improves the smoothness of the sliding at the slide block 301. After the slide block 301 slides, the position of the slide block 301 and the expansion support 3 changes. Moving inward causes the expansion support 3 to move closer to each other, causing the sealing ring to retract. Moving outward causes the sealing ring to be further supported and expanded, increasing the opening size of the sealing ring, which is convenient for subsequent mounting on the hydraulic unit.

[0027] Please see Figure 2 , Figure 6 The hydraulic unit limiting member 5 has a second insertion hole 501 inside for the hydraulic unit rod. The second insertion hole 501 is larger than the first insertion hole 204. A base 101 is installed at the bottom of the sealing ring limiting member 1. A through hole 102 is provided on the outer wall of the sealing ring limiting member 1. The second insertion hole 501 is used for the hydraulic unit to be inserted into the interior. The hydraulic unit limiting member 5 restricts the insertion position of the hydraulic unit to ensure that it can smoothly reach the first insertion hole 204 through the second insertion hole 501 for the subsequent sealing ring fitting process. The base 101 is used to facilitate the user to install and reinforce the sealing ring limiting member 1, thereby improving stability and firmness.
