Description

Technical Field

[0002] Hydraulic cylinders are actuators in hydraulic transmission systems. They are energy conversion devices that convert hydraulic energy into mechanical energy and are widely used in engineering machinery.

Detailed Implementation

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below. Example

[0029] Reference Figures 1 to 8 According to an embodiment of the present invention, a quick-installation and quick-disassembly structure for a hydraulic cylinder is provided, including a drive unit 100, including a base 101 disposed below, two sets of limiting grooves 102 symmetrically opened on the base 101, two sets of driven wheels 103 disposed on one side of the base 101, a meshing wheel 104 disposed on the same side of the base 101 as the two sets of driven wheels 103, and the meshing wheel 104 being located between the two sets of driven wheels 103, a transmission bar 105 transversely disposed outside the meshing wheel 104, and the two ends of the transmission bar 105 being respectively connected to the two sets of driven wheels 103, and an actuating component 107 sleeved on the meshing wheel 104;

[0030] The fixing unit 200 includes a threaded shaft 201 rotatably disposed in a limiting groove 102, two sets of bearing members 202 symmetrically disposed on the threaded shaft 201, with the lower end of the bearing members 202 threadedly connected to the threaded shaft 201, two sets of large parting members 203 slidably connected inside each set of bearing members 202, the two sets of large parting members 203 being arranged vertically, two sets of medium parting members 204 slidably connected inside each set of large parting members 203, the two sets of medium parting members 204 being arranged vertically, and two sets of small parting members 205 slidably connected inside each set of medium parting members 204, the two sets of small parting members 205 being arranged vertically.

[0031] Among them, combined Figure 3 The transmission bar 105 has connecting shafts 1051 rotatably connected to its two ends and three middle positions. The two sets of connecting shafts 1051 at the two ends are respectively inserted into the sides of the two sets of driven wheels 103, and the connecting shaft 1051 in the middle is inserted into the side of the meshing wheel 104.

[0032] During use, the two sets of driven wheels 103 and meshing wheels 104 form a transmission effect through the transmission bar 105. The three cannot rotate independently. When any one of the three rotates, the other two can follow it and rotate in the same direction through the transmission bar 105.

[0033] Among them, combined Figure 4 The actuating component 107 includes a collar 1071 sleeved on the meshing wheel 104, a handle 1072 disposed on one side of the collar 1071 and perpendicular to the connecting shaft 1051, and a receiving groove 1073 opened in the handle 1072. The collar 1071 connects the actuating component 107 as a whole to the meshing wheel 104.

[0034] Furthermore, in combination Figure 4 The actuating component 107 also includes an extension rod 1074 inserted into the handle 1072, a toggle block 1075 fixedly connected to the end of the extension rod 1074, a pressure plate 1076 disposed in the middle section of the extension rod 1074 and the pressure plate 1076 being located in the receiving groove 1073, and a spring 1077 sleeved on the extension rod 1074 and the spring 1077 being located in the receiving groove 1073, with the two ends of the spring 1077 respectively abutting against the inner sides of the pressure plate 1076 and the receiving groove 1073.

[0035] During use, combined with Figure 4 The spring 1077 pushes the extension rod 1074 upward through elastic support, thereby pulling the toggle block 1075 out of the meshing wheel 104, so that the two are not connected. Conversely, pressing the extension rod 1074 can compress the spring 1077, so that the toggle block 1075 is inserted into the meshing wheel 104, thereby achieving a connected connection.

[0036] Furthermore, the meshing wheel 104 has multiple sets of slots that match the lever 1075. The meshing wheel 104 is rotatably connected to the side of the base 101. When the lever 1075 extends into the slot of the meshing wheel 104, the two form a mutual limiting action and can perform synchronous rotation.

[0037] Furthermore, the two ends of the threaded shaft 201 extend to both sides of the base 101, and the part of the threaded shaft 201 connected to the base 101 is a rotatable connection, with the driven wheel 103 fixedly connected to one end of the threaded shaft 201.

[0038] During use, due to the fixed connection between the driven wheel 103 and the threaded shaft 201, the driven wheel 103 can drive the threaded shaft 201 to rotate synchronously, and the rotating threaded shaft 201 can drive the two sets of threaded shafts 201 to achieve clamping or releasing actions.

[0039] In summary, combining Figure 4 By pressing the extension rod 1074, the actuating component 107 can be engaged with the meshing wheel 104. At this time, by turning the actuating component 107, the meshing wheel 104 can be driven to rotate. The rotating meshing wheel 104 will drive the driven wheels 103 at both ends to rotate through the transmission bar 105. The rotating driven wheels 103 will drive the corresponding threaded shaft 201 to drive the fixing unit 200 to perform a clamping action. Rotating the actuating component 107 in the opposite direction can drive the fixing unit 200 to perform a release action. It can be seen that the clamping and releasing action of this device only requires rotating the meshing wheel 104 in different directions by turning the actuating component 107. Compared with the multiple and repetitive screw-tightening actions, the operation time is greatly reduced, thereby realizing the rapid disassembly and assembly of the hydraulic cylinder and significantly improving work efficiency.

[0040] Among them, combined Figure 5 The supporting component 202 includes a vertically arranged base 2021, a mounting groove 2022 opened inside the base 2021, and the two ends of the mounting groove 2022 are arc-shaped. Two sets of arc-shaped sliders 2023 are symmetrically arranged inside the two ends of the mounting groove 2022, and the large parting component 203 is slidably inserted into the arc-shaped sliders 2023. Limiting plates 2024 are symmetrically arranged on both sides of the lower end of the base 2021, and the limiting plates 2024 are slidably inserted into both sides of the limiting groove 102. A sleeve 2025 is arranged at the lower end of the base 2021, and the threaded shaft 201 passes through the sleeve 2025 laterally and is threadedly connected to the sleeve 2025.

[0041] During use, combined with Figure 5Since the two sets of bearing components 202 are symmetrically arranged, and the arc-shaped slider 2023 below the bearing component 202 is threadedly connected to the threaded shaft 201, and the limiting plate 2024 below the bearing component 202 is limited by the limiting groove 102, the threaded shaft 201 can drive the two sets of bearing components 202 to move in opposite directions along the limiting groove 102 when it rotates, thereby realizing the clamping or releasing action, thus achieving the purpose of installing and fixing the oil cylinder and removing the oil cylinder.

[0042] Among them, combined Figure 5 The large parting component 203 includes a semi-circular large parting block 2031, two sets of symmetrical arc-shaped grooves 2032 opened on the inner side of the large parting block 2031, a slot 2033 opened on the outer side of the large parting block 2031, and an arc-shaped slider 2023 matched and inserted into the slot 2033, and an arc-shaped slider 2034 disposed on the inner side of the arc-shaped groove 2032, and the middle parting component 204 slidably inserted into the arc-shaped slider 2034.

[0043] During use, combined with Figure 5 The arc-shaped slider 2023 has an arc-shaped structure with a T-shaped cross-section, and the slot 2033 is matched and inserted into it. Therefore, the large split component 203 can slide along the arc angle direction of the arc-shaped slider 2023. When the inner side of the large split component 203 is squeezed by the outside, the large split component 203 can slide along its arc angle under the limit of the arc-shaped slider 2023, thereby changing its contact state and angle with the external pressure object. The adjusted large split component 203 will generate a set of optimal angles of mutual contact with the external object. This angle can provide stable and powerful support when the large split component 203 performs clamping action. Since a set of bearing components 202 contains two sets of large split components 203, the two sets of bearing components 202 of this device can provide at least four stable clamping angles.

[0044] Among them, combined Figure 5 The split-type component 204 includes a split-type block 2041 located in an arc-shaped groove 2032, two sets of arc-shaped grooves 2042 symmetrically opened on the inner side of the split-type block 2041, and a small split-type component 205 slidably inserted into the arc-shaped groove 2042, a slot 2043 opened on the outer side of the split-type block 2041, and an arc-shaped slider 2034 matchedly inserted into the slot 2043, and an arc-shaped slider 3044 disposed in the arc-shaped groove 2042.

[0045] During use, combined with Figure 5Similar to the cooperation between the bearing component 202 and the large split component 203, the middle split component 204 can be adjusted in position on the side of the large split component 203 when subjected to external force. The position angle adjustment of the middle split component 204 takes precedence over that of the large split component 203. Therefore, the angle adjustment of the large split component 203 is a further supplement to the middle split component 204, thereby making the contact angle between the middle split component 204 and the object more optimal, and thus providing better clamping force. At the same time, each set of large split components 203 contains two sets of middle split components 204, so there are a total of four sets of middle split components 204 in the two sets of large split components 203. This device has a total of four sets of large split components 203, and the four sets of large split components 203 are located on the left and right sides respectively. Therefore, when this device clamps the hydraulic cylinder, there will be four contact angles and points with the cylinder from both sides, and each contact point does not overlap with the others, thereby making the fixing unit 200 fit more closely with the hydraulic cylinder when clamping it.

[0046] Among them, combined Figure 5 The small parting component 205 includes a small parting block 2051 located in the arc-shaped groove 2042, and a slot 3 2052 opened on the outside of the small parting block 2051, and an arc-shaped slider 3 2044 is inserted into the slot 3 2052.

[0047] During use, the small split component 205 operates on the same principle as the large split component 203 and the medium split component 204. When subjected to external force, the small split component 205 can be positioned on the side of the medium split component 204. The position angle adjustment of the small split component 205 takes precedence over that of the medium split component 204. Therefore, the combination of the large split component 203 and the medium split component 204 is an optimization of the angle of the medium split component 204, and the angle adjustment of the medium split component 204 is a further supplement to the medium split component 204. This makes the contact angle between the small split component 205 and the object more optimal, thereby providing better clamping force. The fixing unit 200 has a total of sixteen small split components 205, which are located on the left and right sides respectively. Therefore, when the device clamps the hydraulic cylinder, there will be eight contact angles and points with the cylinder from both sides. Each contact point is non-overlapping, which makes the fixing unit 200 fit closer to the hydraulic cylinder when clamping it, and provides stronger and more stable clamping performance.

[0048] In summary, combining Figure 6 , Figure 7 and Figure 8The drive unit 100 can drive two sets of bearing components 202 on the threaded shaft 201 to move in relative directions, thereby achieving a clamping action. When the bearing components 202 perform the clamping action, the innermost small split component 205 preferentially contacts the hydraulic cylinder and achieves angle adjustment under the action of pressure. Through three angle and state adjustments of the small split component 205, the medium split component 204, and the large split component 203, multiple sets of non-overlapping clamping points can be formed. The specific position of each clamping point changes according to the shape of the object being clamped. These clamping points can cooperate to form different clamping shapes, thereby achieving the purpose of limiting and clamping hydraulic cylinders of different shapes (such as...). Figure 6 Clamping circular hydraulic cylinder 300 Figure 7 Clamping rectangular hydraulic cylinder 400 and Figure 8 The clamping device features a reinforced hydraulic cylinder (as shown in Figure 500), and multiple sets of non-overlapping points increase the contact area between the clamp and the hydraulic cylinder, enhancing the stability of the device during use and ensuring its effectiveness.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
