Description

Technical Field

[0001] This utility model relates to the field of hydrostatic support cylinder technology, and specifically to a hydrostatic support cylinder. Background Technology

[0002] A hydrostatic support cylinder is a hydraulic component with unique performance and applications in the industrial field. Based on the principle of hydrostatic support, the hydrostatic support cylinder works by using an external hydraulic pump to deliver high-pressure oil to various hydrostatic oil chambers inside the cylinder. These oil chambers form an oil film with a certain pressure and thickness between the inner wall of the cylinder and the piston or plunger. This oil film can separate the relatively moving parts, changing the friction between them from solid friction to liquid friction, thereby greatly reducing the frictional resistance between the parts, reducing wear, and improving the smoothness and precision of the cylinder's movement.

[0003] The existing hydrostatic support cylinder consists of a cylinder barrel, piston, hydrostatic oil chamber, and sealing device. The cylinder barrel, as the main structure of the cylinder, is used to house the piston, plunger, and hydraulic oil, and to provide a closed pressure space for the entire system. The piston fits tightly with the inner wall of the cylinder barrel, dividing the inside of the cylinder barrel into two different pressure chambers. The hydrostatic oil chamber is the core structural part of the hydrostatic support cylinder to realize the hydrostatic support function. The sealing device is used to prevent the leakage of hydraulic oil inside the cylinder and the intrusion of external impurities.

[0004] Considering that existing hydrostatic support cylinders typically rely solely on hydraulic oil pressure for support during use, the cylinder barrel is subjected to significant pressure. Over time, or under excessive loads, the cylinder barrel may crack or break, leading to damage and reduced lifespan of the support cylinder. Utility Model Content

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] Reference Figures 1 to 3The diagram illustrates a hydrostatic support cylinder, comprising a cylinder body 1, a contact pad 2, and a protective mechanism 3. The contact pad 2 is fixedly installed at the output end of the cylinder body 1 and has anti-slip textures to increase the friction between the cylinder body 1 and the supported object, thereby improving the support effect. The protective mechanism 3 can be installed and removed from the cylinder body 1. The protective mechanism 3 protects the cylinder body 1 from excessive pressure, preventing cracking and damage. The protective mechanism 3 includes a protective cylinder 31, a base 32, a housing 33, an installation / removal mechanism 34, and a support mechanism 35. The protective cylinder 31 is fixedly installed on the base 32. The protective cylinder 31 is inserted into the cylinder body 1, and the base 32 supports the protective cylinder 31 and the cylinder body 1. The housing 33 is fixedly installed on the protective cylinder 31. There are four housings arranged in a ring array on the housing 33. The support mechanism 35 is slidably installed on the housing 33. The support mechanism 35 is used to support the contact pad 2, thereby reducing the pressure on the cylinder body 1 and improving the service life of the cylinder body 1. The assembly and disassembly mechanism 34 is fixedly installed on the support mechanism 35. The assembly and disassembly mechanism 34 is used to assemble and disassemble the protective mechanism 3, thereby facilitating the maintenance of the cylinder body 1 by the staff and improving the working efficiency of the cylinder body 1.

[0027] Reference Figures 3 to 5 The support mechanism 35 includes a movable block 352, a wedge 354, a spring 355, and a T-shaped rod 356. The movable block 352 is slidably mounted on the housing 33. Four movable blocks 352 are arranged in a circular array to provide stable support for the contact pad 2. The movable block 352 and the wedge 354 are connected by the spring 355, and the wedge 354 is slidably connected to the movable block 352. Through the elastic force of the spring 355, the wedge 354 is always engaged with the slot 359 when no external force is applied, thereby limiting the movement of the movable block 352. The T-shaped rod 356 is fixedly mounted on the wedge 354 and passes through the movable block 352. Through the movement of the T-shaped rod 356, the wedge 354 can be moved.

[0028] Reference Figures 4 to 7The support mechanism 35 also includes a ring 351, a handle 353, and a cylindrical rod 357. The cylindrical rod 357 is rotatably mounted on the movable block 352 and penetrates the housing 33. Four cylindrical rods 357 are arranged in a circular array. The movable block 352 supports the cylindrical rods 357. The handle 353 is fixedly mounted on the ring 351, allowing the operator to easily rotate the ring 351. The movable block 352 has a through groove for the ring 351 to move. The ring 351 is slidably connected to the through groove, and the ring 351 has a guide. The groove 358, through the sliding effect of the ring 351, allows the T-shaped rod 356 to slide along the guide groove 358, thereby driving the wedge block 354 to move and releasing the engagement effect between the wedge block 354 and the slot 359. The housing 33 has a slot 359, and the wedge block 354 engages with the slot 359. Multiple slots 359 are distributed in an array. By engaging the wedge block 354 with the slots 359 at different positions, the moving block 352 is limited at different positions. The T-shaped rod 356 is slidably connected to the guide groove 358, and the guide groove 358 guides the T-shaped rod 356.

[0029] Reference Figure 8 The assembly / disassembly mechanism 34 includes an arc-shaped plate 342, an elastic telescopic rod 343, a locking ring 344, and a guide rod 345. The arc-shaped plate 342 is rotatably connected to the cylindrical rod 357. Two arc-shaped plates 342 are symmetrically distributed, and both ends of the arc-shaped plate 342 are connected to the two cylindrical rods 357 respectively. One end of the elastic telescopic rod 343 is fixedly installed on the cylindrical rod 357, and the cylindrical rod 357 supports the elastic telescopic rod 343, thereby supporting the locking ring 344 and the contact pad 2. The other end of the elastic telescopic rod 343 is connected to the locking ring 344. The hinged joint has four elastic telescopic rods 343. Through the elastic action of the telescopic rods 343, the locking ring 344 maintains its locking effect with the fixed ring 341 under normal conditions. A guide rod 345 is fixedly installed on the locking ring 344 and passes through the arc-shaped plate 342. The guide rod 345 guides the locking ring 344, preventing it from shifting during movement. Simultaneously, pulling the guide rod 345 moves the locking ring 344, thereby releasing the locking effect between the locking ring 344 and the fixed ring 341.

[0030] Reference Figure 2 and Figure 8The mounting and disassembly mechanism 34 also includes a fixing ring 341 and a stop block 346. The fixing ring 341 is fixedly installed on the output end of the cylinder body 1. The fixing ring 341 prevents the fixing ring 341 from falling off. The snap ring 344 has a groove 347. The fixing ring 341 snaps into the groove 347. The snap ring 344 can be installed on the cylinder body 1. The stop block 346 is fixedly installed on the cylindrical rod 357. The stop block 346 supports and limits the arc plate 342.

[0031] The hydrostatic support cylinder, through its protective mechanism, provides support and guidance to the contact pad, allowing the protective mechanism to share some of the pressure on the cylinder body, thus protecting the cylinder body and improving its service life and performance. Furthermore, the included assembly and disassembly mechanism facilitates easy assembly and disassembly of the protective mechanism and cylinder body, enabling maintenance and repair, and improving the cylinder body's utilization rate and work efficiency.
