[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0054] See also Figure 1-15 The present invention discloses a gas valve key shared by humans and machines, comprising:

[0055] A clamping mechanism 1, used for clamping a gas valve stem;

[0056] A telescopic rod mechanism 2, one end of which is connected to the chuck mechanism 1 for telescopic adjustment, driving the chuck mechanism 1 to move along the axial direction of the telescopic rod mechanism 2;

[0057] The handle mechanism 3 is arranged on a side of the telescopic rod mechanism 2 away from the chuck mechanism 1, and is used to assist manual driving of the chuck mechanism 1 to rotate;

[0058] The actuator connector 4 is detachably arranged at the end of the telescopic rod mechanism 2 away from the clamping mechanism 1, and is used for connecting with the actuator.

[0059] The present invention drives the chuck mechanism 1 to move axially along the telescopic rod mechanism 2 by arranging a telescopic rod mechanism 2, so that the chuck mechanism 1 can clamp the gas valve stem in valve wells of different depths, and has wide applicability. At the same time, when manual operation is required, the clamping tightness of the chuck mechanism 1 can be controlled by holding the handle mechanism 3, and after the chuck mechanism 1 is clamped, the chuck mechanism 1 is driven to rotate by pushing the handle mechanism 3 to achieve the opening and closing of the gas valve stem. When machine operation is required, the actuator connector 4 only needs to be connected to the telescopic rod mechanism 2, and the actuator connector 4 can be used to replace manual adjustment of the clamping tightness of the chuck mechanism 1. After that, the actuator can drive the gas valve key to rotate to achieve the opening and closing of the gas valve stem, thereby achieving the purpose of human-machine sharing.

[0060] It should be noted that the actuator is preferably a robotic arm, so that it can simulate manual operation and meet the operation requirements in complex environments.

[0061] In one embodiment, the chuck mechanism 1 includes a first sleeve 11, one end of the first sleeve 11 is connected to the telescopic rod mechanism 2, the other end of the first sleeve 11 is provided with a first support 12 that can move toward and away from the first sleeve 11 and can rotate with the first sleeve 11, a plurality of clamping claws 13 are rotatably provided on the first support 12, a pull rope 14 is provided at one end of the first support 12 close to the first sleeve 11, a second support 15 is sleeved on the first sleeve 11, a connecting rod 16 rotatably connected to the clamping claw 13 is provided on the second support 15, a first compression spring 17 is provided between the first support 12 and the first sleeve 11, and a second compression spring 18 is provided between the plurality of clamping claws 13 and the first sleeve 11;

[0062] The clamping jaw 13 is L-shaped, and consists of a transverse section and a vertical section arranged at the bottom of the transverse section. The two ends of the transverse section are rotatably connected to the connecting rod 16 and the first support 12 respectively, and the second compression spring 18 is located between the connecting rod 16 and the first support 12;

[0063] The telescopic rod mechanism 2 includes a winding assembly 23 connected to the pull rope 14 for winding and releasing the pull rope 14. The handle mechanism 3 is provided with a first control assembly for controlling the winding and releasing operation of the winding assembly 23. The actuator connector 4 is provided with a second control assembly 43 for controlling the winding and releasing operation of the winding assembly 23.

[0064] With this design, after the chuck mechanism 1 is sleeved on the gas valve stem, the pull rope 14 is pulled up to make the clamping jaw 13 rotate to the side close to the gas valve stem under the restriction of the connecting rod 16 until the gas valve stem is clamped. At the same time, the second compression spring 18 applies a thrust to the clamping jaw 13 during the clamping process of the clamping jaw 13, which can effectively avoid the problem of the clamping jaw 13 not clamping firmly due to wear and tear over a long period of time. On the contrary, when the pull rope 14 is loosened, the first compression spring 17 pushes the first support 12 to move down and reset, driving the clamping jaw 13 to rotate in the opposite direction, loosening the gas valve stem, and then the chuck mechanism 1 can be moved up to be taken out of the valve well. By controlling the stretching length of the pull rope 14, the purpose of being compatible with gas valve stems of different models and specifications is achieved, which can effectively solve the problem that the current specifications and sizes of valve opening keys are different, the number of keys carried is large, the volume is large, and the inconvenience of carrying is inconvenient.

[0065] In one embodiment, the number of the clamping jaws 13 and the connecting rods 16 is multiple and all are integer multiples of two, two adjacent clamping jaws 13 and two connecting rods 16 corresponding to the clamping jaws 13 form a group of clamping components, at least two groups of clamping components are provided on the chuck mechanism 1, and the first support 12 and the second support 15 are both provided with multiple angle adjustment components 19 corresponding to the multiple groups of clamping components;

[0066] The angle adjustment assembly 19 includes two side plates 191, and an arc track 192 is arranged between the two side plates 191. One of the clamping jaws 13 and one of the corresponding connecting rods 16 of each group of clamping assemblies are respectively rotatably connected to the arc track 192 on the corresponding angle adjustment assembly 19, and can reciprocate along the arc track 192 toward the other clamping jaw 13 and the other connecting rod 16. Another clamping jaw 13 and another corresponding connecting rod 16 of each group of clamping assemblies are respectively rotatably connected to one of the side plates 191 on the corresponding angle adjustment assembly 19. A first motor 193 is arranged on the connecting rod 16 rotatably arranged on the arc track 192, and a first gear is arranged at the output end of the first motor 193. An external tooth groove meshing with the first gear is opened on the arc track 192 corresponding to the second support 15.

[0067] With this design, by starting the first motor 193 and driving the first gear to move on the arc track 192 with external tooth grooves, the clamping jaws 13 and the connecting rod 16 connected thereto can be driven to move along the arc track 192, thereby changing the horizontal angle between the two clamping jaws 13 in the same group, and further improving the compatibility of the chuck mechanism 1 with different gas valve stems.

[0068] In one embodiment, the second support 15 is slidably sleeved on the first sleeve 11, and the first sleeve 11 is provided with a lifting assembly 5 for driving the second support 15 to move up and down;

[0069] The lifting assembly 5 includes a first screw sleeve 51 rotatably arranged on the top of the second support 15, and the second support 15 moves synchronously with the up and down movement of the first screw sleeve 51. The first sleeve 11 is provided with an external thread groove adapted to the first screw sleeve 51. The lifting assembly 5 also includes a second motor 52 arranged in the first sleeve 11, and the output end of the second motor 52 is provided with a second gear passing through the first sleeve 11. The first screw sleeve 51 is vertically provided with an internal tooth groove meshing with the second gear, and the length of the internal tooth groove is not less than the distance that the first screw sleeve 51 can move up and down.

[0070] With this design, by rotating the first screw sleeve 51 to drive the second support 15 to move up and down, the initial position of the connecting rod 16 and the initial angle of the clamping jaw 13 can be changed, the clamping range of the clamping jaw 13 can be effectively increased, and the compatibility of the chuck mechanism 1 with different gas valve stems can be further improved. At the same time, due to the setting of the second motor 52 and the second gear, the gas valve key can still be connected to the actuator. The actuator can still control the rotation of the first screw sleeve 51 through the second motor 52 to ensure the functional integrity of the gas valve key when it is used by the machine.

[0071] In one embodiment, the telescopic rod mechanism 2 includes a telescopic assembly 21 and a universal connection assembly 22 connecting the telescopic assembly 21 and the clamping mechanism 1;

A connecting rope 215 is provided between the top of the retractable rod 213 and the bottom of the telescopic groove, and is wound around a fixed pulley 214. A third compression spring 216 is provided between the fixing frame 211 and the second telescopic rod 213. A threading hole for the pull rope 14 to pass through is provided on the fixing frame 211 and the second telescopic rod 213. When the pull rope 14 is in a retracted state, it can drive the second telescopic rod 213 and the first telescopic rod 212 to slide into the telescopic rod housing 210. The telescopic assembly 21 also includes a locking component for limiting the up and down movement of the first telescopic rod 212.

[0073] The locking component includes two locking plates 217 which are sleeved outside the first telescopic rod 212 and are arranged in a mirror-symmetrical manner. A clamping hole is opened on the locking plate 217, and the clamping hole is consistent with the external shape of the first telescopic rod 212 and is larger than the external size of the first telescopic rod 212. The two locking plates 217 are sleeved on the outside of the first telescopic rod 212 through the clamping hole. One end of the two locking plates 217 is rotatably connected to the telescopic rod housing 210, and a fourth compression spring 218 is arranged between the other end and the telescopic rod housing 210. The fourth compression spring 218 pushes one end of the two locking plates 217 to approach each other and makes the locking plates 217 abut against the outer surface of the first telescopic rod 212.

[0074] In this design, the fixed pulley 214 and the connecting rope 215 are used to link the first telescopic rod 212 and the second telescopic rod 213, so that when the second telescopic rod 213 moves downward, the connecting rope 215 drives the fixed pulley 214 and the first telescopic rod 212 to move downward together, so that the first telescopic rod 212 and the second telescopic rod 213 can be extended at the same time, which is more convenient and flexible than the current telescopic rod operation that requires each section to be fixed or loosened. Secondly, the third compression spring 216 is used as the extension power of the second telescopic rod 213. When the third compression spring 216 is in a natural state, the second telescopic rod 213 is in a longest extension state. By returning the second telescopic rod 213 to The third compression spring 216 is compressed, and the first telescopic rod 212 is locked at the required position by using the locking component, so that the first telescopic rod 212 and the second telescopic rod 213 are in a retracted state to meet different extension requirements; secondly, because the locking plate 217 of the locking component is pushed by the fourth compression spring 218 to abut against the first telescopic rod 212 when it is in the natural state, the locking component is in a locked state when it is in the natural state. Only by pressing the telescopic control button 219, so that the telescopic control button 219 is inserted into the two locking plates 217, and the locking plates 217 are rotated to unlock the first telescopic rod 212, the first telescopic rod 212 and the second telescopic rod 213 can be normally extended.

[0075] The specific working principle is as follows: press the telescopic control button 219 to extend the first telescopic rod 212 and the second telescopic rod 213, and control the extension length of the first telescopic rod 212 and the second telescopic rod 213 by controlling the release length of the pull rope 14. When the extension length reaches the requirement, stop pressing the telescopic control button 219 to make the locking plate 217 lock the first telescopic rod 212, thereby completing the extension operation of the telescopic rod mechanism 2; press the telescopic control button 219 and reel in the pull rope 14 at the same time to make the clamping mechanism 1 and the universal connection assembly 22 move up to squeeze the first telescopic rod 212 and the second telescopic rod 213 to retract. When the retracted length reaches the requirement, stop pressing the telescopic control button 219 to make the locking plate 217 lock the first telescopic rod 212, thereby completing the retraction operation of the telescopic rod mechanism 2.

[0076] It should be noted that the pull rope 14 controls the clamping tightness of the clamping mechanism 1 only after the first telescopic rod 212 and the second telescopic rod 213 are locked, and an extension section is further added to the original second telescopic rod 213 according to the connection method of the second telescopic rod 213, the fixed pulley 214 and the connecting rope 215, which can further increase the telescopic length of the telescopic rod mechanism 2.

[0077] In one embodiment, the universal connection assembly 22 includes a second sleeve 221 disposed at the bottom of the second telescopic rod 213 and connected to the second telescopic rod 213, a third sleeve 222 is disposed at the bottom of the second sleeve 221 and is plugged into the second sleeve 221 and can move up and down, the bottom of the third sleeve 222 is connected to the first sleeve 11, the internal aperture of the second sleeve 221 is larger than the outer diameter of the third sleeve 222, a latch 223 is disposed on the third sleeve 222 and passes through the second sleeve 221 horizontally, a bar hole is opened on the second sleeve 221 for the latch 223 to move up and down, and two rotationally disposed on the third sleeve 222 for pushing the third sleeve 222 around the latch 223 The L-shaped top block 224 is rotated and offset, and the two L-shaped top blocks 224 are mirror-symmetrical about the axis of the second sleeve 221. The second sleeve 221 is rotatably provided with a second screw sleeve 225, and the second sleeve 221 is provided with an external thread groove adapted to the second screw sleeve 225. The bottom end of the second screw sleeve 225 is rotatably provided with a top ring 226 that can move up and down with the second screw sleeve 225. The maximum distance between the top ends of the two L-shaped top blocks 224 is not less than the outer diameter of the top ring 226. The bottom end of the top ring 226 is provided with at least one groove for avoiding the L-shaped top block 224, and the top ring 226 is in an inverted frustum shape. The bottom end of the top ring 226 is also provided with a first protrusion 227 opposite to the groove;

[0078] One end of the L-shaped top block 224 is tilted upward and away from the second sleeve 221, and the other end of the L-shaped top block 224 is tilted downward and close to the third sleeve 222 and abuts against the third sleeve 222. The rotation center of the L-shaped top block 224 is located in the middle. When the top ring 226 moves downward, it can enter the gap between the L-shaped top block 224 and the second sleeve 221 and squeeze the top of the L-shaped top block 224, so that when one of the L-shaped top blocks 224 is in the groove, the other L-shaped top block 224 abuts against the third sleeve 222 and pushes the third sleeve 222 to deflect to one side.

[0079] In this design, the first protrusion 227 is adjusted not to be directly above the L-shaped top block 224 by rotating the top ring 226, and then the second screw sleeve 225 is rotated to drive the top ring 226 to move down and abut against the L-shaped top block 224. The L-shaped top block 224 is pushed and rotated to limit the rotation margin of the third sleeve 222 in the second sleeve 221, so that in this state, the telescopic rod mechanism 2 and the chuck mechanism 1 are in the same straight line, which can meet the normal clamping and rotation requirements; secondly, the first protrusion 227 is adjusted to be directly above the L-shaped top block 224 by rotating the top ring 226, and then the second screw sleeve 225 is rotated to move one of the L-shaped top blocks 224 into The other L-shaped top block 224 is pushed by the first protrusion 227 to squeeze the third sleeve 222, so that the third sleeve 222 rotates to the other side, so that in this state, the telescopic rod mechanism 2 is not in the same straight line as the chuck mechanism 1, which can meet the clamping requirements of a narrow environment; secondly, by rotating the second screw sleeve 225, the second screw sleeve 225 is in the upper limit position, at this time, the chuck mechanism 1 is connected to the gas valve stem, so that when the chuck mechanism 1 and the telescopic component 21 are at a deflection angle, the chuck mechanism 1 can still be driven to rotate by the rotation of the telescopic component 21 under the cooperation of the third sleeve 222, the bar hole and the latch 223.

[0080] It should be noted that when the actuator is used, the positions of the top ring 226 and the second screw sleeve 225 need to be manually adjusted in advance according to the use environment.

[0081] In one embodiment, the telescopic rod mechanism 2 further includes a winding assembly 23 for winding and releasing the pull rope 14;

[0082] The winding assembly 23 includes a winding shaft 231 disposed at the top of the telescopic rod housing 210 and penetrating the telescopic rod housing 210, two ratchets 232 and two baffles 233 located between the two ratchets 232 are fixedly disposed on the winding shaft 231, one end of the pull rope 14 away from the first support 12 is connected to the winding shaft 231 and is located between the two baffles 233, and a knob 234 is fixedly disposed on one end of the winding shaft 231 located outside the telescopic rod housing 210, and the winding assembly 23 also includes a first ratchet component detachably disposed on the telescopic rod housing 210;

[0083] The first ratchet component includes a first U-shaped plate 235 arranged at the bottom of the ratchet 232 and a bracket 236 detachably arranged on the telescopic rod housing 210. The first U-shaped plate 235 can move in the direction close to and away from the ratchet 232. The first U-shaped plate 235 is provided with a through hole for inserting one end of the bracket 236. A guide column 237 is provided in the through hole, which passes through the bracket 236 and is connected to the first U-shaped plate 235. The guide column 237 is sleeved with a fifth compression spring 238 located at the top of the bracket 236. When the fifth compression spring 238 is in a natural state, the first U-shaped plate 235 abuts against the ratchet 232.

[0084] With this design, the winding length of the pull rope 14 on the winding shaft 231 can be controlled by turning the knob 234, and by setting the first ratchet component, the winding shaft 231 can only rotate to one side under normal conditions, and is restricted by the first U-shaped plate 235 and the ratchet 232 when rotating to the other side. Only when the first U-shaped plate 235 is manually pressed down to release the restriction can the winding shaft 231 rotate to the other side.

[0085] In a specific implementation, the direction in which the ratchet 232 is restricted from rotating by the first U-shaped plate 235 is set as the releasing direction of the pull rope 14, thereby ensuring that the telescopic assembly 21 can maintain a set working length during operation.

[0086] In one embodiment, the handle mechanism 3 includes a handle body 31 rotatably connected to the winding shaft 231 , a second ratchet component 32 is disposed on the handle body 31 , and the first control assembly is composed of the handle body 31 and the second ratchet component 32 ;

[0087] The handle body 31 includes a handle rod 311 and a U-shaped frame 312 disposed at one end of the handle rod 311, and the U-shaped frame 312 is rotatably connected to the winding shaft 231;

[0088] The second ratchet component 32 includes a second U-shaped plate 321 located in the U-shaped frame 312 and used to limit the unidirectional rotation of the ratchet 232. The second U-shaped plate 321 can move in the direction close to and away from the ratchet 232. The second U-shaped plate 321 is provided with a movable rod 322 inserted into the handle rod 311 on the side close to the handle rod 311. The movable rod 322 is sleeved with a sixth compression spring 323 located between the second U-shaped plate 321 and the U-shaped frame 312. The movable rod 322 is located in the handle rod 311. One end of the movable rod 322 is provided with a push rod 324 that penetrates the handle rod 311. The handle rod 311 is provided with a sixth compression spring 323 for receiving the push rod 324. 24 is a guide groove for moving toward and away from one side of the U-shaped frame 312, an adjusting ring 325 is rotatably provided on the handle rod 311 and is located between the pushed rod 324 and the U-shaped frame 312, a second protrusion 326 is provided on the adjusting ring 325 close to the U-shaped frame 312, a trapezoidal block 327 is provided on the side of the U-shaped frame 312 close to the handle rod 311 and is located in the rotation area of ​​the second protrusion 326, and a recess is provided on the trapezoidal block 327 for the second protrusion 326 to be inserted into, when the second protrusion 326 is inserted into the recess on the trapezoidal block 327, the second U-shaped plate 321 is not located in the rotation area of ​​the ratchet 232.

[0089] With this design, when the locking component is in the locked state, the handle body 31 is swung back and forth, so that the second U-shaped plate 321 can drive the ratchet 232 to continuously rotate toward one side of the winding rope 14, thereby quickly adjusting the clamping tightness of the clamping jaw 13, effectively improving the convenience of maintenance personnel during manual operation.

[0090] When the actuator is in use, the adjusting ring 325 needs to be rotated in advance so that the second protrusion 326 is stuck in the groove of the trapezoidal block 327. In this process, the push rod 324 is pushed by the adjusting ring 325, driving the second U-shaped plate 321 to move away from the U-shaped frame 312, so that the second U-shaped plate 321 no longer restricts the ratchet 232, and then the handle mechanism 3 is rotated to fit with the telescopic rod housing 210, so that the handle mechanism 3 no longer affects the normal use of the subsequent actuator.

[0091] It should be noted that the handle mechanism 3 does not interfere with the first ratchet component when rotating.

[0092] In one embodiment, the handle mechanism 3 further includes a telescopic handle 33 disposed at an end of the handle body 31 away from the second ratchet component 32;

[0093] The telescopic handle 33 includes a sleeve 331, a fine-tuning screw sleeve 332 and a handle 333 which are sleeved on the handle rod 311. The fine-tuning screw sleeve 332 and the handle 333 are both threadedly connected to the sleeve 331, and the fine-tuning screw sleeve 332 is located between the handle 333 and the sleeve 331. When the handle 333 moves toward the sleeve 331, the sleeve 331 is squeezed to clamp the handle rod 311. A bending handle 334 is provided on the end of the handle 333 away from the second ratchet component 32. A spring pin 335 is provided in the handle 333, and a plurality of pin slots for the spring pin 335 to be inserted are provided on the bending handle 334.

[0094] With such a design, by moving the sleeve 331, the fine-adjusting screw sleeve 332 and the handle 333 on the handle rod 311 to a certain position, the handle 333 is rotated to squeeze the sleeve 331 so that the sleeve 331 clamps the handle rod 311, thereby limiting the position of the telescopic handle 33 on the handle rod 311 and meeting the length requirements of the handle mechanism 3 in different usage environments.

[0095] It should be noted that by adjusting the position of the fine-tuning screw sleeve 332 on the clamping sleeve 331, each time the handle 333 is rotated to abut against the fine-tuning screw sleeve 332, it can be ensured that the bending handle 334 is in a vertical upward state after being flipped ninety degrees, which is convenient for subsequent operators to hold the bending handle 334 and use the bending handle 334 to drive the entire handle mechanism 3 to rotate.

[0096] In one embodiment, the actuator connector 4 includes a mounting base 41, a flange 42 for connecting to the actuator is arranged on the top of the mounting base 41, a second control component 43 is arranged in the mounting base 41, and the second control component 43 is composed of a third motor and a third gear arranged on the output shaft of the third motor. A hook 44 for hooking to the winding shaft 231 and a hydraulic rod 45 for inserting into the telescopic rod housing 210 are arranged at the bottom of the mounting base 41, and a tooth groove meshing with the third gear is opened on the knob 234. When the hook 44 is hooked to the winding shaft 231, the third gear meshes with the knob 234.

[0097] This design enables the actuator connector 4 to be quickly assembled with the telescopic rod housing 210 through the hook 44 and the hydraulic rod 45, and after assembly, the third motor can be used to drive the knob 234 to rotate to adjust the retracted length of the pull rope 14.

[0098] It should be noted that when the actuator is in use, the first ratchet component can be removed in advance, or a hook plate can be provided on the handle mechanism 3 to hook the first U-shaped plate 235 to move downward. When the handle mechanism 3 is rotated to fit with the telescopic rod housing 210, the hook plate is hooked on the first U-shaped plate 235, driving the first U-shaped plate 235 to move downward and disengage from the ratchet 232. Alternatively, a hook plate can be provided on the telescopic rod housing 210. After the first U-shaped plate 235 is manually moved downward, the hook plate is used to hook the first U-shaped plate 235 to prevent the first U-shaped plate 235 from moving upward and separate from the ratchet 232, and the rotation of the knob 234 is limited by the self-locking property of the third motor.
