Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to an auxiliary installation device for hydraulic cylinders. Background Technology

[0002] To safely and efficiently control the roof and surrounding rock of the mining face and ensure the stability of the working space, hydraulic support is typically used. Currently, hydraulic support manufacturers and repair companies generally use forklifts and slings to assist in the installation of hydraulic cylinders within the hydraulic support system. The hydraulic cylinders are moved to the installation position using forklifts and slings, and the extension length of the cylinder rod is manually adjusted to match the distance between the lugs at both ends of the cylinder with the distance between the two mounting pin holes at the installation position. Then, the lugs are visually inspected to ensure they align with the mounting pin holes. If they do not align, the extension length of the cylinder rod must be readjusted, resulting in low work efficiency. Utility Model Content

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] This utility model provides an auxiliary installation device for hydraulic cylinders, which is used to assist in the installation of hydraulic cylinders. The hydraulic cylinder has a cylinder body, a first clevis, and a second clevis. The first clevis and the second clevis are respectively located at both ends of the cylinder body. The first clevis is connected to the cylinder rod inside the cylinder body, and the first clevis and the second clevis are respectively connected to the mounting pin holes at the installation positions.

[0021] See Figures 1-3As shown, the hydraulic cylinder auxiliary installation device has a first direction X and includes a base 10, a first clamping mechanism 20, a first driving member 30, and a second clamping mechanism 40. The base 10 is used to connect to a robotic arm, which operates the entire device to facilitate moving the hydraulic cylinder to the installation position. The first clamping mechanism 20 is mounted on the base 10 and is used to clamp the cylinder body of the hydraulic cylinder. The first driving member 30 is mounted on the base 10 and spaced apart from the first clamping mechanism 20, and has an actuating end 301. The second clamping mechanism 40 is connected to the actuating end 301. The actuator 301 and the second clamping mechanism 40 are used to clamp the first lug of the hydraulic cylinder. The first driving member 30 drives the actuator 301 to extend and retract along the first direction X. The actuator 301 drives the second clamping mechanism 40 to move synchronously. The second clamping mechanism 40 clamps the first lug and moves synchronously. The position of the first lug can be adjusted, and the extension length of the cylinder rod connected to the first lug can be adjusted, so that the cylinder rod can extend to a set length, so that the distance between the two lugs of the hydraulic cylinder is matched with the distance between the two mounting pin holes at the installation position, which facilitates the installation of the hydraulic cylinder.

[0022] This application utilizes the control of the first driving component 30 to precisely adjust the extension length of the cylinder rod, avoiding repeated adjustments and improving the efficiency of hydraulic cylinder installation. The first driving component 30 is a hydraulic cylinder.

[0023] It should be noted that when the first clamping mechanism 20 clamps the cylinder body of the hydraulic cylinder, the length direction of the cylinder body is parallel to the first direction X, making the length direction of the cylinder rod parallel to the first direction X. This allows the cylinder rod to extend and retract as the first earring moves along the first direction X with the second clamping mechanism 40. The hydraulic cylinder auxiliary installation device also has a second direction Y and a third direction Z, with the first direction X, second direction Y, and third direction Z being mutually perpendicular.

[0024] See Figures 1-3As shown, in some embodiments, the base 10 includes a first hydraulic rotary device 11, a connecting seat 12, and a second hydraulic rotary device 13. The first hydraulic rotary device 11 is used to connect to the robotic arm, and the rotation axis of the first hydraulic rotary device 11 is parallel to the first direction X, and the rotation axis of the first hydraulic rotary device 11 is the first rotation axis. The connecting seat 12 is connected to the first hydraulic rotary device 11. The second hydraulic rotary device 13 is connected to the connecting seat 12, and the rotation axis of the second hydraulic rotary device 13 is perpendicular to the rotation axis of the first hydraulic rotary device 11, and the rotation axis of the second hydraulic rotary device 13 is the second rotation axis. The first rotation axis extends along the first direction X, and the second rotation axis extends along the third direction Z. The first clamping mechanism 20 and the first driving member 30 are respectively disposed on the second hydraulic rotary device 13. The first hydraulic rotary device 11 drives the connecting seat 12, the second hydraulic rotary device 13, the first clamping mechanism 20, the first driving member 30, and the second clamping mechanism 40 to rotate around a first rotation axis; the second hydraulic rotary device 13 drives the first clamping mechanism 20, the first driving member 30, and the second clamping mechanism 40 to rotate around a second rotation axis. The first and second hydraulic rotary devices 11 and 13 provide the base 10 with two degrees of freedom, facilitating adjustment of the posture of the first and second clamping mechanisms 20 and 40 on the base 10, thereby adjusting the posture of the clamped hydraulic cylinder. This ensures that the posture of the hydraulic cylinder corresponds to the two mounting pin holes at the installation position, facilitating the installation and removal of the hydraulic cylinder. The posture of the hydraulic cylinder includes its tilt direction and tilt angle.

[0025] It should be noted that the first hydraulic rotary device 11 and the second hydraulic rotary device 13 are both existing technologies, and will not be described in detail in this utility model.

[0026] In some embodiments, the hydraulic cylinder auxiliary installation device further includes an image acquisition device and a controller. The image acquisition device is connected to the second clamping mechanism 40 and is used to acquire an image of the installation position of the hydraulic cylinder. The image acquisition device, the first hydraulic rotary device 11, and the second hydraulic rotary device 13 are electrically connected to the controller. By acquiring the image of the installation position of the hydraulic cylinder, the controller can easily adjust the first hydraulic rotary device 11 and the second hydraulic rotary device 13, adjust the posture of the base 10, and thus adjust the posture of the clamped hydraulic cylinder to correspond to the two mounting pin holes at the installation position. The image acquisition device is a vision device product, which facilitates the adjustment of the posture of the base 10 in spaces inaccessible to personnel.

[0027] See Figure 1As shown, in some embodiments, the first clamping mechanism 20 includes a support 21 and clamping components 22 disposed on the support 21. The support 21 is connected to the base 10, and the side of the support 21 facing the base 10 has a receiving cavity. A first driving member 30 is inserted into the receiving cavity, such that the installation of the first driving member 30 and the support 21 on the base 10 does not interfere with each other. One or more clamping components 22 are provided, and multiple clamping components 22 are spaced apart along a first direction X on the support 21. The cylinder body is clamped by the clamping components 22.

[0028] See Figure 3 As shown, in some embodiments, the support 21 includes a base plate 211, a first support plate 212, and a second support plate 213. The first support plate 212 and the second support plate 213 are spaced apart on the lower surface of the base plate 211, and the first support plate 212 and the second support plate 213 are respectively connected to the base 10. The gap between the first support plate 212 and the second support plate 213 forms an accommodating cavity. The clamping assembly 22 is disposed on the base plate 211. The first support plate 212 and the second support plate 213 provide support for the base plate 211 and provide space for the installation of the first driving member 30 on the base 10.

[0029] See Figures 4-6As shown, in some embodiments, the clamping assembly 22 includes a mounting plate 221, a second driving member 222, a first clamping block 223, a second clamping block 224, a first transmission rack 225, a second transmission rack 226, and a transmission gear 227. The mounting plate 221 is disposed on the support 21, specifically, the mounting plate 221 is connected to the base plate 211; the first clamping block 223 is slidably disposed on the mounting plate 221, and the first clamping block 223 is provided with a first clamping groove 2231; the second clamping block 224 is slidably disposed on the mounting plate 221, and the second clamping block 224 is provided with a second clamping groove 2241, and the second clamping block 224 and the first clamping block 223 are spaced apart. The opening of the first clamping groove 2231 is opposite to the opening of the second clamping groove 2241; the first transmission rack 225 is disposed on the side of the first clamping block 223 facing the mounting plate 221; the second transmission rack 226 is disposed on the side of the second clamping block 224 facing the mounting plate 221; the transmission gear 227 is rotatably mounted on the mounting plate 221, and the transmission gear 227 meshes with the first transmission rack 225 and the second transmission rack 226 respectively; the first clamping block 223 and the second clamping block 224 are respectively connected to the second driving member 222, and the second driving member 222 drives the first clamping block 223 and the second clamping block 224 to move closer to each other or further away from each other. The first support plate 212 and the second support plate 213 may have grooves to avoid interfering with the movement of the second driving member 222; the seat plate 211 also has grooves at the position opposite to the clamping assembly 22 to provide installation space for the clamping assembly 22. The first transmission rack 225 and the second transmission rack 226 are arranged at intervals and parallel to each other, and are respectively located on both sides of the transmission gear 227. The mounting plate 221 has a frame structure to avoid interference with the installation of the first transmission rack 225 and the second transmission rack 226. The first clamping block 223 and the second clamping block 224 are located on the upper side of the mounting plate 221, and the second driving member 222 is located on the lower side of the mounting plate 221.

[0030] The second driving component 222 can be a telescopic cylinder, or optionally, the second driving component 222 can be a telescopic hydraulic cylinder. The second driving member 222 has a first end 2221 and a second end 2222. The first end 2221 is connected to the first clamping block 223, and the second end 2222 is connected to the second clamping block 224. The second driving member 222 drives the first end 2221 to extend and retract along the second direction Y. The first end 2221 drives the first clamping block 223 to move synchronously. The first clamping block 223 slides along the mounting plate 221. When the first clamping block 223 moves, the first transmission rack 225 moves synchronously with the first clamping block 223, and the first transmission rack 225 drives the transmission gear 227 to rotate. The rotation of the transmission gear 227 drives the second transmission rack 226 to move. The second transmission rack 226 drives the second clamping block 224 to move synchronously. The second clamping block 224 slides along the mounting plate 221, thereby realizing the opposite movement of the first clamping block 223 and the second clamping block 224, so that the first clamping block 223 and the second clamping block 224 move closer to each other or further away from each other. The first clamping block 223 and the second clamping block 224 can clamp the cylinder body of the hydraulic cylinder when they are close to each other, and can release the clamped cylinder body of the hydraulic cylinder when they are far apart from each other.

[0031] The first clamping block 223 is provided with a first clamping groove 2231, and the second clamping block 224 is provided with a second clamping groove 2241. When clamping the cylinder body, the cylinder body portion is located within the first clamping groove 2231 and the second clamping groove 2241. The first clamping groove 2231 and the second clamping groove 2241 limit the cylinder body and increase the contact area between the first clamping block 223, the second clamping block 224 and the cylinder body, preventing the cylinder body from detaching from between the first clamping block 223 and the second clamping block 224. Preferably, both the first clamping groove 2231 and the second clamping groove 2241 are V-shaped.

[0032] See Figures 4-6 As shown, in some embodiments, the clamping assembly 22 further includes a first connecting plate 228, a second connecting plate 229, and a force sensor 230. The first connecting plate 228 connects the first clamping block 223 and the second driving member 222; the second connecting plate 229 connects the second clamping block 224 and the second driving member 222; the force sensor 230 is disposed between the first clamping block 223 and the first connecting plate 228, or between the second clamping block 224 and the second connecting plate 229. The force sensor 230 is used to detect the clamping force. By detecting the clamping force through the force sensor 230, it is possible to avoid insufficient clamping force and damage to the cylinder body due to insufficient clamping force or excessive clamping force. The first connecting plate 228 is connected to the end of the first clamping block 223 away from the second clamping block 224; the second connecting plate 229 is connected to the end of the second clamping block 224 away from the first clamping block 223. The first end 2221 and the second end 2222 of the second driving component 222 are respectively connected to the first connecting plate 228 and the second connecting plate 229.

[0033] In some embodiments, the force sensor 230 is positioned opposite to the bottom of the first clamping groove 2231 or the bottom of the second clamping groove 2241. The clamping force applied by the first clamping block 223 to the cylinder is perpendicular to the bottom of the first clamping groove 2231, and the clamping force applied by the second clamping block 224 to the cylinder is perpendicular to the bottom of the second clamping groove 2241. By positioning the force sensor 230 opposite to the bottom of the groove, the force sensor 230 can directly receive the transmitted positive pressure perpendicular to the bottom of the groove, avoiding force off-center loading or interference from component forces.

[0034] See Figure 1 , Figures 7-9 As shown, in some embodiments, the second clamping mechanism 40 includes a mounting base 41, a third driving member 42, a first clamping arm 43, and a second clamping arm 44. The mounting base 41 is connected to the actuating end 301; the third driving member 42 is disposed on the mounting base 41; the first clamping arm 43 is slidably disposed on the mounting base 41, and a first boss 431 is provided at the end of the first clamping arm 43 away from the mounting base 41; the second clamping arm 44 is slidably disposed on the mounting base 41, and a second boss 441 is provided at the end of the second clamping arm 44 away from the mounting base 41. The first boss 431 and the second boss 441 are disposed opposite to each other. The first clamping arm 43 and the second clamping arm 44 are disposed at a distance from each other, and the first clamping arm 43 and the second clamping arm 44 are respectively connected to the third driving member 42 for transmission. The third driving member 42 drives the first clamping arm 43 and the second clamping arm 44 to move closer to each other or further away from each other along the second direction Y. When the second clamping mechanism 40 clamps the first earring, the first protrusion 431 and the second protrusion 441 partially insert into the first earring, limiting its position. A third driving member 42 is used as a single power source to drive the first clamping arm 43 and the second clamping arm 44 to move closer together to clamp the first earring, or to move further apart to release the first earring. The first protrusion 431 and the second protrusion 441 are adapted to the first earring, making it easier to clamp the first earring.

[0035] See Figure 7 and Figure 8 As shown, in some embodiments, the end of the first boss 431 facing the second boss 441 is tapered; the end of the second boss 441 facing the first boss 431 is also tapered. This arrangement makes it easier for the first boss 431 and the second boss 441 to be inserted into the first earring, and allows the first boss 431 and the second boss 441 to be used with first earrings of different inner diameters.

[0036] See Figure 1As shown, in some embodiments, the second clamping mechanism 40 further includes a guide rod 45, which is slidably connected to the base 10. The sliding direction of the guide rod 45 is parallel to the first direction X. The mounting base 41 is connected to the guide rod 45 and is also connected to the actuating end 301. The guide rod 45 not only guides the movement direction of the mounting base 41 but also provides connection support for the mounting base 41, ensuring the stability of the movement of the mounting base 41. Multiple guide rods 45 can be provided.

[0037] In some embodiments, the third drive element 42 is a motor, which is connected to the first clamping arm 43 and the second clamping arm 44 respectively. (See also...) Figures 7-9 As shown, the second clamping mechanism 40 also includes a transmission screw 46, and a third driving member 42 is connected to the transmission screw 46 to drive the transmission screw 46 to rotate. The first clamping arm 43 and the second clamping arm 44 are respectively threaded onto the transmission screw 46, and the threads of the transmission screw 46 at the mounting positions of the first clamping arm 43 and the second clamping arm 44 are in opposite directions, so that when the transmission screw 46 rotates, the first clamping arm 43 and the second clamping arm 44 move in opposite directions along the transmission screw 46, allowing the first clamping arm 43 and the second clamping arm 44 to move closer to or further away from each other. A first slider 432 is provided at the end of the first clamping arm 43, and a second slider 442 is provided at the end of the second clamping arm 44. The first slider 432 and the second slider 442 are slidably connected to the mounting base 41.

[0038] See Figure 1 and Figure 7 As shown, the mounting base 41 includes a first base 411 and a second base 412, which are arranged vertically and connected to each other. The guide rod 45 and the actuating end 301 are both connected to the second base 412. The first clamping arm 43 and the second clamping arm 44 are slidably mounted on the first base 411. Specifically, the first slider 432 and the second slider 442 are slidably mounted on the first base 411, and the transmission screw 46 is rotatably mounted on the first base 411. The first base 411 is provided with a mounting groove 4111, in which the first slider 432, the second slider 442, and the transmission screw 46 are all mounted. The mounting groove 4111 provides mounting space for the first slider 432, the second slider 442, and the transmission screw 46. The groove wall of the mounting groove 4111 can be provided with a guide groove. The first slider 432 and the second slider 442 are provided with flanges, which are inserted into the guide groove. The guide groove limits the first slider 432 and the second slider 442, allowing them to slide along the mounting groove 4111.

[0039] The working process of this utility model is as follows: During the installation of the hydraulic cylinder, the cylinder body is clamped by the first clamping mechanism 20, and the first lug of the hydraulic cylinder is clamped by the second clamping mechanism 40. The first driving member 30 drives the actuator 301 to move along the first direction X, causing the second clamping mechanism 40 to move the first lug away from the cylinder body, thus adjusting the extension length of the cylinder rod. Then, the posture of the hydraulic cylinder is adjusted by the first hydraulic rotary device 11 and the second hydraulic rotary device 13. The robotic arm is operated to align the first and second lugs of the hydraulic cylinder with the two mounting pin holes at the installation position. Pins are manually inserted into the first lug and its corresponding mounting pin hole, and the second lug and its corresponding mounting pin hole, thus completing the installation of the hydraulic cylinder.

[0040] It should be noted that the hydraulic cylinder auxiliary installation device of this utility model can not only be used to assist in the installation of hydraulic cylinders, but also to assist in the disassembly of hydraulic cylinders. When disassembling the hydraulic cylinder, the overall posture of the base 10 is adjusted by the first hydraulic rotary device 11 and the second hydraulic rotary device 13, thereby adjusting the posture of the first clamping mechanism 20 so that the clamping space of the first clamping mechanism 20 is aligned with the cylinder body of the hydraulic cylinder. The cylinder body of the hydraulic cylinder is clamped by the first clamping mechanism 20, and the connecting pins of the first and second lugs and mounting pin holes are manually removed. The clamped hydraulic cylinder can then be transferred out by operating a robotic arm.

[0041] The above description is only a preferred embodiment of the present utility model.
