Abstract

The application discloses a gas valve spoon shared by man and machine, which comprises a chuck mechanism for clamping a gas valve stem, and a telescopic rod mechanism connected with the chuck mechanism at one end and used for telescopic adjustment to drive the chuck mechanism to move along the axial direction of the telescopic rod mechanism. According to the application, the chuck mechanism can clamp the gas valve stem in the valve well with different depths by driving the chuck mechanism to move along the axial direction of the telescopic rod mechanism, so the applicability is wide. When manual operation is needed, the chuck mechanism can be controlled to clamp with different tightness by only holding the handle mechanism. After the chuck mechanism is clamped, the handle mechanism is pushed to drive the chuck mechanism to rotate, so that the opening and closing of the gas valve stem are realized. When machine operation is needed, the actuating mechanism connector is connected to the telescopic rod mechanism, so that the actuating mechanism connector can replace manual operation to adjust the clamping tightness of the chuck mechanism.

[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0054] Please refer toFigures 1-15 The application discloses a gas valve spoon shared by man and machine, which comprises:

[0055] a chuck mechanism 1 for clamping a gas valve stem;

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

[0057] a handle mechanism 3 arranged on the side of the telescopic rod mechanism 2 away from the chuck mechanism 1, for assisting manual driving of the chuck mechanism 1 to rotate;

[0058] an actuator connector 4 detachably arranged on the end of the telescopic rod mechanism 2 away from the chuck mechanism 1, for being connected with an actuator.

[0059] According to the application, the telescopic rod mechanism 2 drives the chuck mechanism 1 to move along the axial direction of the telescopic rod mechanism 2, so that the chuck mechanism 1 can clamp the gas valve stem in the valve well with different depths, and has wide applicability. When manual operation is needed, the chuck mechanism 1 can be controlled in clamping tightness 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, so that the gas valve stem can be opened and closed. When machine operation is needed, the actuator connector 4 is connected to the telescopic rod mechanism 2, so that the actuator connector 4 can replace manual operation to adjust the clamping tightness of the chuck mechanism 1, and then the actuator can drive the gas valve spoon to rotate, so that the gas valve stem can be opened and closed, thereby achieving the purpose of being shared by man and machine.

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

[0061] In an embodiment, the chuck mechanism 1 comprises a first sleeve 11, one end of the first sleeve 11 is connected with the telescopic rod mechanism 2, the other end of the first sleeve 11 is provided with a first support 12 capable of moving towards and away from the first sleeve 11 and capable of rotating with the first sleeve 11, a plurality of clamping jaws 13 are arranged on the first support 12 in a rotating manner, a pull rope 14 is arranged on the 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 connected with the clamping jaws 13 in a rotating manner is arranged on the second support 15, a first compression spring 17 is arranged between the first support 12 and the first sleeve 11, and a second compression spring 18 is arranged between the clamping jaws 13 and the first sleeve 11.

[0062] The clamping jaw 13 is L-shaped and comprises a horizontal section and a vertical section arranged at the bottom of the horizontal section, the two ends of the horizontal section are connected with the connecting rod 16 and the first support 12 in a rotating manner, and the second compression spring 18 is located between the connecting rod 16 and the first support 12.

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

[0064] In this way, when the clamp head mechanism 1 is sleeved on the gas valve stem, the pull rope 14 is pulled upward to make the clamping jaw 13 rotate to the side close to the gas valve stem under the limitation of the connecting rod 16 until the gas valve stem is clamped, and at the same time, the second compression spring 18 can effectively avoid the problem that the clamping jaw 13 is not clamped tightly due to long-term use and wear because the second compression spring 18 exerts a pushing force on the clamping jaw 13 during the clamping process. Conversely, when the pull rope 14 is loosened, the first compression spring 17 pushes the first support 12 to move downward to reset, driving the clamping jaw 13 to rotate in the opposite direction to loosen the gas valve stem, so that the clamp head mechanism 1 can be taken out from the valve well by moving upward. By controlling the stretching length of the pull rope 14, the compatibility of different models and specifications of the gas valve stem can be achieved, which can effectively solve the problems of different specifications, models and sizes of the valve spoon, large number of carried ones, large volume and inconvenience of carrying.

[0065] In an embodiment, the number of clamping jaws 13 and connecting rods 16 is multiple and an integer multiple of two, two adjacent clamping jaws 13 and two connecting rods 16 corresponding to the clamping jaws 13 form a clamping assembly, the clamp head mechanism 1 is provided with at least two clamping assemblies, and the first support 12 and the second support 15 are each provided with a plurality of angle adjusting assemblies 19 corresponding to the plurality of clamping assemblies.

[0066] The angle adjusting assembly 19 comprises two side plates 191, and an arc-shaped track 192 is arranged between the two side plates 191. One clamping jaw 13 and one connecting rod 16 corresponding to the clamping jaw 13 of each clamping assembly are respectively rotationally connected to the arc-shaped track 192 of the corresponding angle adjusting assembly 19 and can reciprocate along the arc-shaped track 192 to the other clamping jaw 13 and the other connecting rod 16. The other clamping jaw 13 and the other connecting rod 16 corresponding to the clamping jaw 13 of each clamping assembly are respectively rotationally connected to one of the side plates 191 of the corresponding angle adjusting assembly 19. A first motor 193 is arranged on the connecting rod 16 rotationally arranged on the arc-shaped track 192. The output end of the first motor 193 is provided with a first gear. An outer tooth groove meshing with the first gear is formed in the arc-shaped track 192 corresponding to the second support 15.

[0067] In this way, by starting the first motor 193, the first gear can walk on the arc-shaped track 192 with the outer tooth groove, driving the clamping jaw 13 and the connecting rod 16 connected thereto to move along the arc-shaped track 192, changing the horizontal angle between the two clamping jaws 13 in the same group, and further improving the compatibility of the clamp head mechanism 1 to different gas valve stems.

[0068] In an embodiment, the second support 15 is 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 comprises a first screw sleeve 51 rotatably arranged on the top of the second support 15, the second support 15 moves synchronously with the first screw sleeve 51 moving up and down, the first sleeve 11 is provided with an external thread groove matched with the first screw sleeve 51, and the lifting assembly 5 further comprises a second motor 52 arranged in the first sleeve 11, the output end of the second motor 52 is provided with a second gear penetrating through the first sleeve 11, the first screw sleeve 51 is vertically provided with an internal tooth groove matched 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] In this way, the initial position of the connecting rod 16 and the initial angle of the clamping jaw 13 can be changed by rotating the first screw sleeve 51 to drive the second support 15 to move up and down, which can effectively increase the clamping interval of the clamping jaw 13 and further improve the compatibility of the chuck mechanism 1 to different valve stems of gas valves. Meanwhile, due to the arrangement of the second motor 52 and the second gear, the gas valve spoon can still be controlled by the second motor 52 to rotate the first screw sleeve 51 after being connected with the actuating mechanism, thereby ensuring the functional integrity of the gas valve spoon when being used by a machine.

[0071] In an embodiment, the telescopic rod mechanism 2 comprises a telescopic assembly 21 and a universal connecting assembly 22 connecting the telescopic assembly 21 and the chuck mechanism 1;

[0072] The telescopic assembly 21 comprises a telescopic rod shell 210, the inside of the telescopic rod shell 210 is provided with a telescopic slot, the telescopic slot is provided with a fixing frame 211, the telescopic rod shell 210 is provided with a first telescopic rod 212 capable of moving up and down in the telescopic slot, the first telescopic rod 212 is provided with a second telescopic rod 213 capable of moving up and down in the first telescopic rod 212, the horizontal cross sections of the first telescopic rod 212 and the second telescopic rod 213 are both polygons, the top of the first telescopic rod 212 is provided with a fixed pulley 214, the top of the second telescopic rod 213 and the bottom of the telescopic slot are provided with a connecting rope 215 winding around the fixed pulley 214, the fixing frame 211 and the second telescopic rod 213 are provided with a third compression spring 216, and the fixing frame 211 and the second telescopic rod 213 are both provided with a rope passing hole for the pulling rope 14 to pass through, the pulling rope 14 in the winding state can drive the second telescopic rod 213 and the first telescopic rod 212 to slide into the telescopic rod shell 210, and the telescopic assembly 21 further comprises a locking component for limiting the first telescopic rod 212 to move up and down;

[0073] The locking component comprises two locking plates 217 which are mirror-symmetrically arranged and sleeved on the first telescopic rod 212, the locking plates 217 are provided with clamping holes which are in conformity with the shape of the outer part of the first telescopic rod 212 and are larger than the size of the outer part of the first telescopic rod 212, the two locking plates 217 are sleeved on the outer part of the first telescopic rod 212 through the clamping holes, one end of the two locking plates 217 is rotationally connected with the telescopic rod shell 210, and the other end is provided with a fourth compression spring 218 which pushes the one end of the two locking plates 217 to be close to each other and makes the locking plates 217 abut against the outer side of the first telescopic rod 212 to prevent the first telescopic rod 212 from moving through friction force, the locking component further comprises a telescopic control button 219 which is arranged on the telescopic rod shell 210 and is rotationally connected with the telescopic rod shell 210 through a torsion spring, the telescopic control button 219 is provided with a pointed part, the telescopic rod shell 210 is provided with an opening for the pointed part to insert a telescopic slot, and when the telescopic control button 219 rotates to the side close to the telescopic rod shell 210, the torsion spring is gradually compressed and the pointed part is inserted between the two locking plates 217 to push the two locking plates 217 to move to the opposite side, thereby releasing the abutment of the locking plates 217 and the first telescopic rod 212.

[0074] In this way, the first telescopic rod 212 and the second telescopic rod 213 are linked through the fixed pulley 214 and the connecting rope 215, so that when the second telescopic rod 213 moves downward, the fixed pulley 214 and the first telescopic rod 212 move downward together due to the action of the connecting rope 215, thereby realizing the simultaneous extension of the first telescopic rod 212 and the second telescopic rod 213, which is more convenient and flexible than the current telescopic rod operation which needs to be fixed or loosened every section. Secondly, the third compression spring 216 serves 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 the longest extension state, by retracting the second telescopic rod 213, the third compression spring 216 is compressed, at the required position, the first telescopic rod 212 is locked by the locking component, so that the first telescopic rod 212 and the second telescopic rod 213 are in the retracted state, thereby meeting different extension requirements. Thirdly, the locking plates 217 of the locking component are pushed by the fourth compression spring 218 to abut against the first telescopic rod 212 in the natural state, so that the locking component is in the locked state in the natural state, only by pressing the telescopic control button 219, the telescopic control button 219 is inserted between the two locking plates 217 to make the locking plates 217 rotate to unlock the first telescopic rod 212, the first telescopic rod 212 and the second telescopic rod 213 can normally extend.

[0090] When the actuator is used, the adjusting ring 325 needs to be rotated in advance, so that the second protrusion 326 is clamped into the sunken groove of the trapezoidal block 327, in this process, the push rod 324 is pushed by the adjusting ring 325, and the second U-shaped plate 321 is driven to move away from the U-shaped frame 312, so that the second U-shaped plate 321 no longer limits the ratchet 232, and then the handle mechanism 3 is rotated to be attached to the telescopic rod shell 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 part when rotating.

[0094] In this way, by moving the sleeve 331, the fine adjustment sleeve 332 and the handle 333 on the handle rod 311, when reaching a certain position, the handle 333 is rotated to press 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 requirement of the handle mechanism 3 in different use environments.

[0095] It should be noted that by adjusting the position of the fine adjustment sleeve 332 on the sleeve 331, the bent handle 334 can be ensured to be in the vertical upward state after being turned by ninety degrees each time the handle 333 is rotated to abut against the fine adjustment sleeve 332, thereby facilitating the subsequent operator to hold the bent handle 334 and rotate the entire handle mechanism 3 by using the bent handle 334.
