Description

Technical Field

[0001] This application relates to the field of marine equipment technology, and in particular to a hydraulic cylinder steering gear. Background Technology

[0002] A hydraulic steering gear is a device that uses hydraulic oil as its working medium to turn and maintain the rudder position of a ship. Depending on the power source, it can be divided into manual, electric, and electro-hydraulic steering gears. Electro-hydraulic steering gears are reliable, easy to operate, lightweight, durable, economical, and easy to maintain and manage, making them ideal steering devices for ships.

[0003] In related technologies, Chinese utility model patent CN205632993U discloses a digital hydraulic cylinder servo motor, including a digital hydraulic cylinder, an oil tank, a hydraulic control island, an energy accumulator, an oil pump, a motor, a connecting rod, and a double-arm rocker arm; the digital hydraulic cylinder is composed of a cylinder, a digital valve, a stepper motor, and a piston; the outlet end of the oil pump is connected to the energy accumulator, and the energy accumulator supplies oil to the digital hydraulic cylinder through an oil pipe; the piston rod of the piston is provided with a connecting rod, and the double-arm rocker arm is driven through the connecting rod.

[0004] Regarding the aforementioned technologies, the inventors believe that the piston rod on the hydraulic cylinder is prone to scratches after long-term use. When the piston rod is scratched, the oil in the hydraulic cylinder is prone to leaking out from the piston rod, affecting the use of the hydraulic cylinder servo and causing environmental pollution. Summary of the Invention

[0005] In order to reduce the pollution of the environment in which the hydraulic cylinder servo motor is used, this application provides a hydraulic cylinder servo motor.

[0006] The hydraulic cylinder steering gear provided in this application adopts the following technical solution: A hydraulic cylinder servo motor includes a servo handle and a rocker arm mounted on the servo handle. Connecting rods are hinged to both ends of the rocker arm. A hydraulic cylinder body is mounted on the end of the connecting rod away from the rocker arm. A receiving sleeve is fitted onto the piston rod of the hydraulic cylinder body. The end of the receiving sleeve away from the rocker arm is fitted onto the hydraulic cylinder body. A receiving annular groove for collecting hydraulic oil from the hydraulic cylinder body is formed on the inner wall of the receiving sleeve. A locking sleeve is slidably disposed on the inner wall of the receiving sleeve. A locking annular groove for sliding engagement with the locking sleeve is formed on the inner side wall of the receiving annular groove away from the locking sleeve. An adjusting component for driving the locking sleeve to move is provided on the receiving sleeve. A locking component for locking the hydraulic cylinder body and the receiving sleeve is provided on the receiving sleeve.

[0007] By adopting the above technical solution, the operator uses the locking assembly to install the storage sleeve onto the hydraulic cylinder body. When the piston rod of the hydraulic cylinder body is scratched, the hydraulic oil of the hydraulic cylinder body leaks out from the piston rod and flows into the storage ring groove inside the storage sleeve. When the operator finds that the piston rod of the hydraulic cylinder body is scratched, the operator can adjust the assembly to move the locking sleeve, insert the locking sleeve into the locking ring groove, thereby sealing the storage ring groove and preventing the leaked hydraulic oil from flowing out. Then, the operator uses the locking assembly to release the locking state of the storage sleeve 14, and then collects and cleans the leaked hydraulic oil, preventing the operating environment of the hydraulic cylinder servo from being contaminated and affecting the use of the hydraulic cylinder servo, and making it convenient for the operator to use.

[0008] Preferably, the adjusting assembly includes an adjusting disc rotatably mounted on the end of the receiving sleeve away from the hydraulic cylinder body, and an adjusting column passing through the locking sleeve. The adjusting column is fixedly connected to the adjusting disc, and both the adjusting column and the adjusting disc are slidably fitted onto the piston rod of the hydraulic cylinder body. A rubber ring is provided on the end of the adjusting column near the receiving ring groove, and the rubber ring is fitted onto the piston rod of the hydraulic cylinder body. An inclined surface is provided on the side of the rubber ring near the receiving ring groove. The adjusting column is threadedly engaged with the locking sleeve. A guide block is fixedly connected to the outer wall of the locking sleeve, and a guide groove for sliding engagement with the guide block is provided on the inner wall of the receiving sleeve.

[0009] By adopting the above technical solution, the operator rotates the adjusting disc, which in turn drives the adjusting column to rotate. The rotating column then moves the locking sleeve, which, under the action of the guide block, inserts into the locking ring groove. This facilitates the operator in collecting leaked hydraulic oil and prevents hydraulic oil from flowing out during disassembly. The rubber ring design allows the hydraulic oil on the piston rod of the hydraulic cylinder body to be scraped off, preventing hydraulic oil from leaking through the piston rod of the hydraulic cylinder body. The inclined surface of the rubber ring allows the scraped-off hydraulic oil to flow into the collection ring groove, making it convenient for the operator to collect leaked hydraulic oil.

[0010] Preferably, the locking assembly includes a locking slider passing through the storage sleeve, a locking rod installed on the locking slider near the end of the hydraulic cylinder body, the hydraulic cylinder body having a locking slot for engaging with the locking rod, and the storage sleeve having a driving assembly for moving the locking slider.

[0011] By adopting the above technical solution, the operator uses the drive component to move the locking slider, and the movement of the locking slider drives the movement of the locking rod, thereby controlling the locking rod to be inserted and separated from the locking slot, making it convenient for the operator to fix the storage sleeve.

[0012] Preferably, the driving assembly includes a helical toothed ring slidably inserted into the storage sleeve, a driving rod fixedly connected to the helical toothed ring, a locking slider having helical teeth that mesh with the helical toothed ring, an arc-shaped groove on the storage sleeve, the driving rod extending out of the storage sleeve and slidingly engaging with the inner wall of the arc-shaped groove, a locking groove on the storage sleeve for sliding engagement with the locking slider, a return spring fixedly connected to the locking slider, the end of the return spring away from the locking slider being fixedly connected to the inner end face of the locking groove, and a locking assembly for fixing the locking slider on the storage sleeve.

[0013] By adopting the above technical solution, the operator moves the drive rod, which moves within the arc-shaped groove, causing the helical gear ring to rotate. The rotation of the helical gear ring causes the locking slider to move. At this time, the return spring is in a compressed state. The movement of the locking slider causes the locking rod to move, and the locking rod moves away from the locking slot, thereby releasing the locking state between the storage sleeve and the hydraulic cylinder body. The operator releases the drive rod, and the locking slider moves under the action of the return spring, causing the locking rod to move. The locking rod is inserted into the locking slot, making it convenient for the operator to fix the storage sleeve. Then, the operator uses the locking assembly to fix the locking slider, thereby preventing the storage sleeve from falling off due to accidental contact with the drive rod, and improving the stability of the storage sleeve.

[0014] Preferably, the locking assembly includes a locking rod passing through the storage sleeve, a locking spring fixedly connected to the locking rod, a locking slot for engaging with the locking rod on the locking slider, a locking groove for sliding with the locking rod on the inner sidewall of the locking groove, a locking groove for sliding with the locking rod on the inner sidewall of the locking groove, a locking spring having its end away from the locking rod fixedly connected to the inner end face of the locking groove, and a control component for controlling the locking rod to move away from the locking slot on the storage sleeve.

[0015] By adopting the above technical solution, the operator uses the control component to move the locking rod away from the locking slot, thereby releasing the locking slider from its fixed state, making it convenient for the operator to unlock the storage sleeve. At this time, the locking spring is in a compressed state. When the operator releases the drive rod, the locking slider moves back to its original position under the action of the return spring. At this time, the locking rod slides on the side wall of the locking slider under the action of the locking spring. When the locking rod is inserted into the locking slot, the locking rod slides to the position of the locking slot and enters the locking slot under the action of the locking slot, thereby fixing the locking slider and making it convenient for the operator to lock the storage sleeve.

[0016] Preferably, the control component includes a control gear rotatably mounted inside the storage sleeve and a control rack passing through the storage sleeve. The locking rod has teeth on its side near the control gear, the teeth on the locking rod meshing with the control gear, the control gear meshing with the control rack, and the end of the control rack away from the locking slider passing through the inner wall of the locking ring groove and able to abut against the locking sleeve.

[0017] By adopting the above technical solution, when the piston rod of the hydraulic cylinder body is scratched, the operator rotates the adjusting disc to move the locking sleeve. The locking sleeve is inserted into the locking ring groove and abuts against the control rack. The operator continues to rotate the adjusting disc, which drives the locking sleeve to move. The movement of the locking sleeve drives the control rack to move. The movement of the control rack drives the control gear to rotate. The rotation of the control gear drives the locking rod away from the locking slider, thereby releasing the locking state of the locking slider and making it convenient for the operator to unlock and remove the storage sleeve.

[0018] Preferably, the locking rod passes through the locking slider, and the locking slider has a positioning slot for sliding cooperation with the locking rod. A positioning spring is fixedly connected to the end of the locking rod that passes through the locking slider. The end of the positioning spring away from the locking rod is fixedly connected to the inner end face of the positioning slot. An inclined surface is provided on the end of the locking rod near the hydraulic cylinder body.

[0019] By adopting the above technical solution, the locking slider is initially fixed. The operator places the storage sleeve onto the hydraulic cylinder body and moves the storage sleeve. At this time, the end of the hydraulic cylinder body slides on the inclined surface of the locking rod. The operator continues to move the storage sleeve, and the locking rod enters the positioning slot. At this time, the locking rod slides on the side of the hydraulic cylinder body. When the locking rod moves to the position of the locking slot, the locking rod is inserted into the locking slot under the action of the positioning spring, thereby fixing the storage sleeve. This makes it convenient for the operator to install and prevents the storage sleeve from being removed when hydraulic oil is not collected.

[0020] Preferably, a limiting disc is rotatably connected to the piston rod of the hydraulic cylinder body, and a fixing screw is fixedly connected to the side of the limiting disc away from the hydraulic cylinder body. The fixing screw passes through the end of the connecting rod near the limiting disc, and the fixing screw is threadedly engaged with the connecting rod. A fixing component for fixing the limiting disc and the connecting rod is provided on the limiting disc.

[0021] By adopting the above technical solution, after the hydraulic oil in the hydraulic cylinder body leaks, the operator uses the fixing component to release the fixing of the limiting disc. Then, the operator rotates the limiting disc, which drives the fixing screw to rotate. The rotation of the fixing screw drives the connecting rod to move, thereby separating the piston rod of the hydraulic cylinder body from the connecting rod, making it convenient for the operator to replace the scratched piston rod.

[0022] Preferably, the fixing assembly includes a fixing plate slidably disposed within the limiting disc, a fixing rod mounted on the fixing plate, and a movable screw passing through the fixing plate. The connecting rod has multiple fixing holes on its side near the fixing rod for insertion and engagement with the fixing rod. The limiting disc has a limiting groove for sliding engagement with the fixing plate. The movable screw passes through the limiting disc and is threaded into the fixing plate. A knob is installed on the end of the movable screw extending out of the limiting disc. The fixing rod passes through the fixing plate, and the fixing plate has a fixing groove for sliding engagement with the fixing rod. A fixing spring is fixedly connected to the end of the fixing rod that enters the fixing plate, and the end of the fixing spring away from the fixing rod is fixedly connected to the inner end face of the fixing groove.

[0023] By adopting the above technical solution, the operator rotates the limiting disc, which drives the fixing screw to rotate. The rotation of the fixing screw connects the connecting rod to the piston rod of the hydraulic cylinder body. Then, the operator rotates the knob, which drives the moving screw to rotate. The moving screw moves the fixing plate, which in turn moves the fixing rod. The fixing rod and the connecting rod abut against the end face of the limiting disc. At this time, the fixing spring is in a compressed state. The operator then continues to rotate the limiting disc, which causes the fixing rod to slide on the end face of the connecting rod. When the fixing rod moves to the position of the fixing hole, it inserts into the fixing hole under the action of the fixing spring, thus fixing the limiting disc. The operator then rotates the knob, which drives the fixing plate to move via the moving screw. The fixing plate then moves the fixing rod, thereby releasing the locking of the limiting disc and facilitating the operator's disassembly of the piston rod of the hydraulic cylinder body.

[0024] Preferably, a positioning rod is provided on the side of the fixing plate away from the fixing rod. The fixing plate has a positioning groove for sliding with the positioning rod. An adjusting spring is fixedly connected to the end of the positioning rod that enters the fixing plate. The end of the adjusting spring away from the positioning rod is fixedly connected to the inner end face of the positioning groove. The end of the positioning rod that exits the fixing plate passes through the limiting disc. The adjusting disc has a plurality of positioning holes for inserting and engaging with the positioning rod.

[0025] By adopting the above technical solution, when the piston rod of the hydraulic cylinder body is scratched and hydraulic oil leaks, the operator retracts the piston rod of the hydraulic cylinder body. At this time, the limiting disc and the adjusting disc are in contact. Then, the operator rotates the knob, which drives the fixing rod away from the fixing hole through the fixing plate. At this time, the positioning rod abuts against the adjusting disc under the action of the fixing plate, and the adjusting spring is in a compressed state. Then, the operator rotates the limiting disc, which drives the positioning rod to slide on the side of the adjusting disc. When the positioning rod slides to the position of the positioning hole, it inserts into the positioning hole under the action of the adjusting spring. The operator continues to rotate the limiting disc, which drives the adjusting disc to rotate. At this time, the connecting rod separates from the fixing screw, and the locking sleeve enters the locking ring groove under the action of the adjusting column, thereby releasing the locking slider from the locked state. Then, the operator moves the drive rod, which drives the locking insert away from the locking slot, thereby releasing the fixation of the receiving sleeve. This makes it convenient for the operator to replace and disassemble the piston rod of the hydraulic cylinder body and to collect and clean the leaked hydraulic oil.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The operator uses the locking assembly to install the storage sleeve onto the hydraulic cylinder body. When the piston rod of the hydraulic cylinder body is scratched, the hydraulic oil of the hydraulic cylinder body leaks out from the piston rod and flows into the storage ring groove inside the storage sleeve. When the operator finds that the piston rod of the hydraulic cylinder body is scratched, the operator can adjust the assembly to move the locking sleeve, insert the locking sleeve into the locking ring groove, thereby sealing the storage ring groove and preventing the leaked hydraulic oil from flowing out. Then, the operator uses the locking assembly to release the locking state of the storage sleeve, and then collects and cleans the leaked hydraulic oil to prevent the operating environment of the hydraulic cylinder servo from being contaminated and affecting the use of the hydraulic cylinder servo, and to facilitate the operator's use. 2. The operator rotates the adjusting disc, which in turn rotates the adjusting column. The rotating column then moves the locking sleeve, which, under the action of the guide block, inserts into the locking ring groove. This facilitates the operator in collecting leaked hydraulic oil and prevents hydraulic oil from flowing out during disassembly. The rubber ring design allows the hydraulic oil on the piston rod of the hydraulic cylinder body to be scraped off, preventing hydraulic oil from leaking through the piston rod of the hydraulic cylinder body. The inclined surface of the rubber ring allows the scraped hydraulic oil to flow into the collection ring groove, making it convenient for the operator to collect leaked hydraulic oil. 3. When the piston rod of the hydraulic cylinder body is scratched and hydraulic oil leaks, the operator retracts the piston rod of the hydraulic cylinder body. At this time, the limiting disc and the adjusting disc are in contact. Then, the operator rotates the knob, which drives the fixing rod away from the fixing hole through the fixing plate. At this time, the positioning rod abuts against the adjusting disc under the action of the fixing plate, and the adjusting spring is in a compressed state. Then, the operator rotates the limiting disc, which drives the positioning rod to slide on the side of the adjusting disc. When the positioning rod slides to the position of the positioning hole, it inserts into the positioning hole under the action of the adjusting spring. The operator continues to rotate the limiting disc, which drives the adjusting disc to rotate. At this time, the connecting rod separates from the fixing screw, and the locking sleeve enters the locking ring groove under the action of the adjusting column, thereby releasing the locking slider from the locked state. Then, the operator moves the drive rod, which drives the locking insert away from the locking slot, thereby releasing the fixation of the receiving sleeve. This makes it convenient for the operator to replace and disassemble the piston rod of the hydraulic cylinder body and to collect and clean the leaked hydraulic oil. Attached Figure Description

[0050] Reference Figure 4 The storage sleeve 14 is equipped with a drive assembly 4 for moving the locking slider 31. The drive assembly 4 includes a helical toothed ring 41 and a drive rod 42. The helical toothed ring 41 is vertically arranged and disposed inside the storage sleeve 14. The axis of the helical toothed ring 41 coincides with the axis of the storage sleeve 14, and the helical toothed ring 41 and the storage sleeve 14 are rotatably engaged. The locking slider 31 is provided with helical teeth on the side of the locking slider 31 near the helical toothed ring 41, and the helical teeth of the locking slider 31 mesh with the helical toothed ring 41.

[0051] Reference Figure 4The drive rod 42 is vertically positioned and passes through the storage sleeve 14, where it is fixedly connected to the helical toothed ring 41. An arc-shaped groove 43 is provided on the upper surface of the storage sleeve 14, surrounding its axis. The outer side of the drive rod 42 slides against the inner wall of the arc-shaped groove 43.

[0052] Reference Figure 4 The storage sleeve 14 is provided with a locking assembly 5 for fixing and locking the slider 31. The locking assembly 5 includes a locking rod 51 and a locking spring 52. The locking rod 51 is horizontally arranged and is located on the side of the locking slider 31 near the limiting disc 131. The locking rod 51 passes through the inner wall of the locking groove 44. A locking groove 54 is horizontally opened inside the storage sleeve 14. The outer wall of the locking rod 51 slides and engages with the inner wall of the locking groove 54.

[0053] Reference Figure 4 A locking slot 53 is provided on the locking slider 31. The end of the locking rod 51, which protrudes from the inner wall of the locking groove 44, enters the locking slider 31. The inner side wall of the locking slot 53 and the outer side wall of the end of the locking rod 51 entering the locking slider 31 slide in a sliding engagement. The locking spring 52 is horizontally set and is located in the locking groove 54. One end of the locking spring 52 is fixedly connected to the inner end face of the locking groove 54, and the other end of the locking spring 52 is fixedly connected to the end of the locking rod 51. The locking rod 51 is designed to facilitate the operator in fixing the locking slider 31 and prevent the operator from accidentally touching the drive rod 42, causing the storage sleeve 14 to fall off. The inclined surface of the locking rod 32 allows the operator to install the storage sleeve 14 without removing the locking slider 31, making it convenient for the operator to install the storage sleeve 14.

[0054] Reference Figure 4 The storage sleeve 14 is provided with a control component 6 for controlling the locking rod 51 to move away from the locking slot 53. The control component 6 includes a control gear 61 and a control rack 62. The control gear 61 is vertically arranged and rotatably connected to the storage sleeve 14. The end of the locking rod 51 that enters the storage sleeve 14 is provided with teeth, and the teeth of the locking rod 51 mesh with the control gear 61.

[0055] Reference Figure 2 , Figure 4 The control rack 62 is horizontally set and passes through the receiving sleeve 14. The control rack 62 meshes with the control gear 61. The end of the control rack 62 away from the locking slider 31 passes through the inner end face of the locking ring groove 143. The end of the control rack 62 that passes through the inner end face of the locking ring groove 143 can abut against the locking sleeve 142.

[0056] The operator rotates the adjusting disc 21, which moves the locking sleeve 142. The locking sleeve 142 drives the control gear 61 to rotate via the control rack 62. The rotation of the control gear 61 moves the locking rod 51 away from the locking slider 31. Then the operator moves the drive rod 42, which drives the locking slider 31 to move via the helical gear ring 41. The locking slider 31 drives the locking rod 32 to move, thereby releasing the locking state of the storage sleeve 14 and making it easier for the operator to disassemble the storage sleeve 14.

[0057] The implementation principle of a hydraulic cylinder servo motor in this application embodiment is as follows: When the piston rod of the hydraulic cylinder body 13 is scratched, the operator retracts the piston rod. At this time, the limiting disc 131 abuts against the adjusting disc 21. The operator rotates the knob 76 to release the locking between the connecting rod 12 and the limiting disc 131. Then, the operator rotates the adjusting disc 21. The adjusting disc 21 drives the fixing screw 132 to rotate through the limiting disc 131, thereby releasing the connection between the piston rod of the hydraulic cylinder body 13 and the connecting rod 12. The rotation of the adjusting disc 21 drives the locking sleeve 142 to be inserted into the locking ring groove 143, thereby sealing the receiving ring groove 141 and preventing the hydraulic oil in the receiving ring groove 141 from leaking.

[0058] The locking sleeve 142 is inserted into the locking ring groove 143, which drives the locking rod 51 away from the locking slider 31. Then the operator moves the drive rod 42, thereby moving the locking rod 32 away from the hydraulic cylinder body 13, releasing the locking state of the receiving sleeve 14, and collecting and cleaning the leaked hydraulic oil to prevent the hydraulic cylinder servo motor's operating environment from being contaminated, affecting the use of the hydraulic cylinder servo motor, and making it convenient for the operator to use.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
