Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire-fighting equipment, in particular to a quick opening and closing valve auxiliary device. BACKGROUND

[0002] In highway traffic, tunnels are usually built for pedestrians and vehicles to pass through in areas with large undulating terrain or obstacles. Relative to other traffic sections, tunnels have the characteristics of relative closure, especially long tunnels, which need to pay attention to tunnel ventilation and fire-fighting problems, and must set up a fire-fighting emergency system, for example, laying fire-fighting water pipes in the tunnel, and setting up a valve every certain distance to ensure the need for quickly extinguishing fires in each section of the tunnel, and regularly maintaining the pipes and valves to ensure tunnel fire safety.

[0003] The valve of the fire-fighting pipeline usually includes a valve body arranged inside the pipeline and a disc-shaped handle located outside the pipeline. During the maintenance and use of the fire-fighting water pipe in the tunnel, the handle needs to be manually turned to drive the valve to open and close. In order to meet the sealing performance, high pressure requirement and anti-misoperation requirement of the valve, a large driving force is required for the opening and closing of the fire-fighting pipeline valve, which results in a very time-consuming and laborious operation. During maintenance, maintenance personnel often need to open and close numerous valves in tunnels along the highway within a short period of time, which tests the physical strength of the maintenance personnel and slows down the maintenance progress, and also easily causes waste of fire-fighting water.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0053] The embodiment of the present application provides a quick opening and closing valve auxiliary device for cooperating with an electric wrench to drive a valve of a fire-fighting pipeline to quickly open and close.

[0054] As shown in Figure 1 , Figure 2 and Figure 3 , the auxiliary device 1000 includes a first base body 1, a clamping mechanism 2, a poking member 3, a second base body 4 and a transmission mechanism 5.

[0055] The first base body 1 has a first side X1 and a second side X2 along a first direction X.

[0056] The clamping mechanism 2 is arranged on the first base body 1, and the clamping mechanism 2 has a clamping piece extending towards the first side X1. As shown in Figure 4 and Figure 5 , the clamping mechanism 2 is used to clamp the pipeline 3001 to be fixed relative to the valve.

[0057] One end of the poking member 3 is rotatably arranged on the first base body 1, and the other end of the poking member 3 extends towards the first side X1. As shown in Figure 3 ,Figure 3 The auxiliary device 1000 is cut open to show the internal structure, except the toggle 3. The toggle 3 includes a connecting disc 31 and a pawl 32. The connecting disc 31 is connected to the output end of the transmission mechanism 5. The pawl 32 is fixed to the connecting disc 31 at one end and extends towards the first side X1 at the other end. The number of the pawls 32 can be one or more. Figure 5 As shown, when the clamping mechanism 2 clamps the pipe 3001, the other end of the pawl 32 extends to the rotation path of the valve. It should be noted that the handle 3002 of the valve generally has two types. One is a rod-shaped handle 3002 which is fixedly connected to the rotation shaft of the valve, so that the handle can be held by hand to operate the valve to rotate to open or close. The other is a steering wheel-shaped handle which includes a ring and a plurality of spaced spokes. Each spoke is connected to the ring and the rotation shaft of the valve. The ring can be held by hand to operate the valve to rotate to open or close. In the auxiliary device 1000 provided in the embodiment of the present application, the pawl 32 is located in the rotation path of the rod-shaped handle 3002, so that the pawl 32 can drive the rod-shaped handle 3002 to rotate. Alternatively, the pawl 32 is arranged in the interval between adjacent spokes, so that the pawl 32 can drive the steering wheel-shaped handle 3002 to rotate.

[0058] The second base 4 is connected to the second side X2 of the first base 1 and has a receiving cavity 411 and an opening 412 which communicates with the receiving cavity 411.

[0059] The transmission mechanism 5 is arranged in the receiving cavity 411. The output end of the transmission mechanism 5 is connected to the toggle 3 through the first base 1. The input end of the transmission mechanism 5 is located at the second side X2. The input end of the transmission mechanism 5 is provided with a plug-in hole 511 which corresponds to the opening 412. The plug-in hole 511 is used to cooperate with the output shaft 2000 of the electric wrench to drive the toggle 3 to open or close the valve.

[0060] Please refer to Figure 3 As shown, the transmission mechanism 5 includes a first gear 51, a second gear 52 and a transmission rod 53.

[0061] The first gear 51 and the second gear 52 are rotatably arranged in the receiving cavity 411. The first gear 51 is engaged with the second gear 52. The diameter of the first gear 51 is smaller than that of the second gear 52.

[0062] The plug-in hole 511 is arranged at the axis of the first gear 51.

[0063] One end of the transmission rod 53 is connected to the second gear 52 and the other end is connected to the toggle 3.

[0064] The auxiliary device 1000 provided by the embodiment of the application is used for driving the valve of the fire-fighting pipeline 3001 to be opened and closed quickly by the electric wrench, and saves manpower, reduces the working difficulty of the maintenance personnel and speeds up the maintenance progress.

[0065] In some embodiments, the transmission rod 53 can be connected at the eccentric position of the second gear 52, and the first base 1 is provided with an arc-shaped slot (not shown in the figure) through which the transmission rod 53 passes and can rotate circumferentially.

[0066] In some embodiments, the transmission rod 53 can also be connected at the axial position of the second gear 52. The first base 1 has a through hole 11 (as shown in Figure 6 , Figure 6 which is hidden from view, the second base 4, the transmission mechanism 5 and the actuating piece 3), in combination with Figure 3 shown, the actuating piece 3 is located at the end of the through hole 11 away from the accommodating cavity 411, the transmission rod 53 passes through the through hole 11 and connects the actuating piece 3 and the second gear 52, and the actuating piece 3, the through hole 11 and the second gear 52 are coaxially arranged.

[0067] When the electric wrench is rotated forward and reversely, the transmission mechanism 5 increases the torque and reduces the speed, so as to drive the valve to be opened and closed by the actuating piece 3.

[0068] The output shaft 2000 of the electric wrench is generally a square shaft, as shown in Figure 2 and Figure 5 shown, the insertion hole 511 is a square hole to match the output shaft 2000 of the electric wrench.

[0069] In an embodiment of the application, as shown in Figure 6 , the first gear 51 has a receiving hole 512 parallel to the insertion hole 511, and the side wall of the insertion hole 511 has a connecting hole 513 communicating with the receiving hole 512;

[0070] The transmission mechanism 5 further includes a first positioning pin 54, an unlocking piece 55 and a first elastic piece 56.

[0071] The first positioning pin 54 is movably arranged in the connecting hole 513 and has a locking position and a release position. As shown in Figure 6 , the first positioning pin 54 extends into the insertion hole 511 in the locking position, so as to lock the output shaft 2000 of the electric wrench. As shown in Figure 7As shown, the first positioning pin 54 is retracted from the connecting hole 513 in the release position to release the output shaft 2000 of the electric wrench. It should be noted that in order to tighten different specifications of anchor fasteners such as screws, bolts, nuts, etc., the electric wrench needs to be equipped with multiple adapters. The output shaft 2000 of the common electric wrench is generally provided with a mounting hole 2001 for mounting the adapter, and the mounting hole 2001 is perpendicular to the output shaft.

[0072] The unlocking member 55 is movably arranged in the accommodating hole 512 and has an abutting position and an avoiding position. As shown Figure 6 As shown, the unlocking member 55 abuts against the first positioning pin 54 in the abutting position to limit the first positioning pin 54 in the locked position. As shown Figure 7 As shown, the unlocking member 55 is released in the avoiding position. Exemplarily, the unlocking member 55 is arranged as a rod member with an avoiding groove 551. In the abutting position, the avoiding groove 551 is staggered with the first positioning pin 54, and the outer surface of the unlocking member 55 abuts against the first positioning pin 54 to prevent the first positioning pin 54 from retracting, thereby locking the output shaft 2000 of the electric wrench. In the avoiding position, the avoiding groove 551 corresponds to the first positioning pin 54, and the first positioning pin 54 can retract into the avoiding groove 551, thereby unlocking the output shaft 2000 of the electric wrench.

[0073] The first elastic member 56 connects the unlocking member 55 and the inner wall of the accommodating hole 512 and has a tendency to keep the unlocking member 55 in the abutting position. When the output shaft 2000 of the electric wrench is inserted into the plug-in hole 511, the unlocking member 55 is pressed to the avoiding position, and the first elastic member 56 is compressed, so that the first positioning pin 54 can retract to the release position. After insertion, the unlocking member 55 is released, the first elastic member 56 drives the unlocking member 55 to return to the abutting position, the inner wall of the avoiding groove 551 forms a bevel with the first positioning pin 54, the unlocking member 55 returns to the abutting position to drive the first positioning pin 54 to return to the locked position and plug into the mounting hole 2001 on the output shaft 2000 of the electric wrench, thereby locking the output shaft 2000 of the electric wrench. After the valve opening and closing is completed, the unlocking member 55 is pressed again, and the output shaft 2000 of the electric wrench can be pulled out.

[0074] Optionally, the transmission mechanism 5 further comprises a second elastic member 541 connected between the first positioning pin 54 and the inner wall of the connecting hole 513, which has a tendency to keep the first positioning pin 54 in the release position, so as to avoid failure of the output shaft 2000 of the electric wrench during plugging or pulling out.

[0075] The embodiments of the present application ensure the stable connection between the output shaft 2000 of the electric wrench and the device during use by arranging the first positioning pin 54, the unlocking member 55 and the first elastic member 56 in the first gear 51, further reducing the difficulty of manual operation, and avoiding the safety hazards caused by accidental disengagement.

[0076] In some embodiments, the second base body 4 comprises a body part 41 and an extension part 42, the accommodating cavity 411 is arranged on the body part 41, one end of the extension part 42 is connected to the body part 41 and the other end is inserted into the through hole 11; the body part 41 is provided with a second positioning pin 413, the clamping mechanism 2 is provided with a positioning hole 2111, the second positioning pin 413 is inserted into the positioning hole 2111 to fix the second base body 4 and the clamping mechanism 2. By arranging the second base body 4 as the body part 41 and the extension part 42, the assembly of the first base body 1 and the second base body 4 is more simple and stable, and by arranging the second positioning pin 413 structure on the body part 41, after the clamping mechanism 2 is fixed to the pipeline 3001, the second base body 4 is further fixed by the second positioning pin 413, which avoids the problem that the second base body 4 may shake during use, and improves the safety of the auxiliary device 1000.

[0077] In some embodiments, as shown in Figure 3 , 4 , 5, the clamping mechanism 2 provided by the embodiments of the present application comprises a fixed clamping part 21 and a movable clamping part 22, that is, the fixed clamping part and the movable clamping part 22 cooperate to achieve clamping and fixing with the pipeline 3001.

[0078] The fixed clamping part 21 comprises a fixed part 211 and a first clamping part 212, the fixed part 211 is fixedly connected to the first base body 1, one end of the first clamping part 212 is fixedly connected to the fixed part 211 and the other end extends towards the first side X1, and the first clamping part 212 is used to abut against one side of the pipeline 3001 of the valve.

[0079] The movable clamping part 22 comprises a rotating disc 221 and a second clamping part 222, the rotating disc 221 is rotatably connected to the first base body 1, one end of the second clamping part 222 is fixedly connected to the rotating disc 221 and the other end extends towards the first side X1, and the second clamping part 222 cooperates with the first clamping part 212 to clamp and fix the pipeline 3001 of the valve.

[0080] Optionally, the positioning hole 2111 is arranged on the fixed part 211 to make the second base body 4 more stable.

[0081] In some embodiments, as shown in Figure 4 and Figure 8 , the clamping mechanism 2 further comprises a locking assembly 23, comprising a lock box 231 and a lock rod 232, the lock box 231 is arranged on the first clamping part 212, the lock rod 232 is arranged on the second clamping part 222, the lock rod 232 is inserted into the lock box 231, and the lock rod 232 cooperates with the lock box 231 through a ratchet 2321 and a rack to limit the movement of the second clamping part 222 away from the first clamping part 212.

[0082] In some embodiments, as shown inFigure 8 As shown, the lock box 231 comprises a box body 2311 connected to the first clamping part 212 and a first side X1 wall 2312 movably connected to the box body 2311 along the first direction X and having a first position and a second position. One of the ratchet 2321 and the rack is arranged on the lock rod 232 and the other is arranged on the first side X1 wall 2312. The rack cooperates with the ratchet 2321 when the first side X1 wall 2312 is in the first position and disengages from the ratchet 2321 when the first side X1 wall 2312 is in the second position. The first side X1 wall 2312 can be movably connected to the box body 2311 along the first direction X by arranging protrusions on both ends of the first side X1 wall 2312 perpendicular to the first direction X, extending the protrusions along the first direction X, arranging a sliding groove on the box body 2311 extending along the first direction X, and cooperating the protrusions with the sliding groove to achieve the connection of the first side X1 wall 2312 with the box body 2311 while allowing the first side X1 wall 2312 to slide along the first direction X. Only the first side X1 wall 2312 in the first position is shown in the figure, and those skilled in the art should understand that after the first side X1 wall 2312 slides upward along the first direction X, the first side X1 wall 2312 disengages from the lock rod 232, releasing the cooperation of the rack with the ratchet 2321, and thus releasing the restriction on the first clamping part 212 and the second clamping part 222.

[0083] In some embodiments, referring again to Figure 4 , the extension 42 is movably inserted into the through hole 11 along the first direction X; the locking assembly 23 further comprises a connecting member 233 connecting the first side X1 wall 2312 with the body part 41. The connecting member 233 can be a rigid structure or a flexible rope as long as it can provide tension to switch the first side X1 wall 2312 between the first position and the second position when lifting and lowering the second base body 4.

[0084] After the movable clamping part 22 and the fixed clamping part 21 are clamped on the pipeline 3001, the second base body 4 is lowered, and the first side X1 wall 2312 is in the first position under the action of gravity and the connecting member 233 to cooperate with the lock rod 232 to lock the fixed clamping part 21 and the movable clamping part 22.

[0085] The lock rod 232 is arc-shaped, and the lock box 231 has a slot for accommodating the lock rod 232, the slot has the same curvature as the lock rod 232, and the lock rod 232 can slide along the slot to adapt to the locking requirements of different sizes of the pipeline 3001.

[0086] When the auxiliary device 1000 needs to be removed from the pipeline 3001, the worker lifts the second base body 4, pulls the first side X1 wall 2312 to the second position through the connecting piece 233, unlocks the fixed clamping piece 21 and the movable clamping piece 22, so that the movable clamping piece 22 can be opened, and then the entire auxiliary device 1000 can be removed by continuing to lift.

[0087] In some embodiments, as shown in Figure 2 and Figure 5 The second gear 52 is provided with a marker 521, and the second base body 4 is provided with an arc-shaped observation window corresponding to the position of the marker 521.

[0088] In some embodiments, the edge of the arc-shaped observation window is provided with a scale, so that the worker can clearly know the opening degree of the valve.

[0089] In some embodiments, when the valve rotates from the closed position to the open position, the marker rotates around the rotation axis of the second gear 52 to form a first arc line, and the two ends of the arc-shaped observation window are beyond the first arc line. After long-term use of the valve, sometimes more rotation angle is needed to achieve the sealing of the pipeline 3001. The observation window provided in the embodiments of the present application can avoid the marker from being out of the observation window, and is also helpful for the maintenance personnel to observe the fatigue condition of the valve.
