Description

Technical Field

[0001] The invention relates to the field of quick connectors, and in particular to an electrically driven multi-way quick connector docking device. Background Art

[0002] A quick connector refers to a mechanical device used to quickly connect and disconnect hydraulic or pneumatic fluid pipelines, generally including a male connector, a female connector and a locking mechanism. Engineering machinery products often use quick connectors in fluid pipelines to quickly connect and disconnect hydraulic and pneumatic pipelines. In the prior art, a multi-way quick connector docking device can connect multiple pipelines at one time. Its working principle is mainly to use a mechanical docking mechanism to convert the rotational motion of the handle into the opposite motion of the two quick connector mounting parts. After docking, the locking mechanism ensures that the quick connector remains connected. However, it basically relies on the operator to manually complete the pipeline connection one by one, which is complicated, time-consuming and labor-intensive.

[0003] Existing technologies include patented multi-way quick connector combinations (CN 105065826 B) and multi-way connection equipment with a control device (CN 110095976 B). The following problems exist: 1) The mechanical docking mechanism is laborious to use: it mainly relies on the user to operate the handle to implement the docking action. When the connected quick connectors are slightly larger in size, slightly more in number, or there is residual pressure in the pipeline, a larger torque needs to be applied. 2) The reliability of the locking device is not high: when there is vibration or pipeline impact in the operating conditions, it is not safe enough to rely solely on pin holes or steel balls to lock and fix the quick connectors. 3) There is a large demand for reserved installation space: sufficient space needs to be reserved when the handle body is installed. In addition, when driving the docking device for rotational movement, it is generally required that there are no obstructions within the operating radius. When the handle is increased to reduce the operating torque, the operating radius will also increase accordingly.

[0004] As my country's construction machinery industry accelerates its transformation and upgrading, the high-end trend of various types of construction machinery products is becoming more and more obvious. The continuous expansion of its functions and the continuous growth of product tonnage have led to more and more parts that need to be assembled and disassembled during operation and transportation. In addition, due to the high pressure and large flow of the working pipeline, quick connectors often use threaded locking form. During use, it is inevitable that there will be problems such as time-consuming and labor-intensive disassembly and assembly, poor reliability, and a large demand for reserved installation space.

[0005] Therefore, it is necessary to develop a new type of multi-way quick connector docking device in a targeted manner to simplify the operation, save time and effort, and require less space. Summary of the invention

[0006] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides an electrically driven multi-way quick connector docking device, which simplifies operation, saves time and effort; improves reliability and safety; requires less reserved installation space; and can promptly obtain the docking status of the quick connector.

[0007] Technical solution: An electrically driven multi-way quick connector docking device of the present invention is characterized by comprising a male connector assembly for installing and fixing a quick male connector, a female connector assembly for installing and fixing a quick female connector, an electric drive device for connecting the male connector assembly and the female connector assembly, and a docking locking device;

[0008] The male connector assembly includes a mounting plate 1, one or more quick male connectors, and a group of positioning pins; the female connector assembly includes a mounting plate 2, one or more quick female connectors, and a group of guide holes; the electric drive device includes a drive motor and a docking shaft; the docking locking device includes a docking sleeve, a spring seat, a return spring, a sleeve base, and a safety lock;

[0009] The electric drive device and the docking locking device are respectively installed on the first mounting plate and the second mounting plate.

[0010] Wherein, the male joint assembly is provided with one or more quick male joints, and the male joint assembly is provided with a group of positioning pins; the female joint assembly is provided with one or more quick female joints, and the female joint assembly is provided with a group of guide holes corresponding to the positioning pins.

[0011] Among them, one end of the docking shaft of the electric drive device is rigidly connected to the drive motor and can rotate synchronously with the output shaft of the drive motor. The other end of the docking shaft is provided with a protruding pin, a blind hole and a contact switch installed inside.

[0012] Among them, the bottom of the docking sleeve of the docking locking device is connected and fixed to the sleeve base, and the docking sleeve is provided with a spiral groove, a through hole and a limit step; the spring seat and the return spring are placed between the docking sleeve and the sleeve base.

[0013] Among them, the safety lock is installed on the side of the mounting plate where the docking locking device is located, and is used for locking the male connector assembly and the female connector assembly after they are docked in place. The safety lock includes a lock cap, a lock sleeve, a locking spring and a lock shaft.

[0014] The locking sleeve is fixedly connected to the side hole of the mounting plate where the docking locking device is located, the locking shaft is connected to the locking cap after being inserted into the locking sleeve, and the locking spring is located between the locking sleeve and the locking shaft.

[0015] The electrically driven multi-way quick connector docking device of the present invention is characterized in that when docking, it includes the following steps:

[0016] 1) Positioning before docking: The positioning pin of the male connector assembly is inserted into the guide hole of the female connector assembly, and the protruding pin of the docking shaft of the electric drive device is rotated to form a match with the spiral groove opening section of the docking sleeve of the docking locking device;

[0017] 2) Start docking: Start the drive motor to make the docking shaft rotate synchronously, and the protruding pin of the docking shaft moves along the spiral groove track of the docking sleeve, gradually pulling the male connector assembly and the female connector assembly to fit each other, and the quick male connector and the quick female connector move towards each other to achieve docking;

[0018] 3) Locking after docking: After the male connector assembly and the female connector assembly are docked, the docking shaft moves axially to compress the spring seat and the return spring to the bottom of the through hole and no longer block the lock shaft. Under the action of the locking spring, the lock shaft passes through the through hole of the docking sleeve and pops out into the blind hole of the docking shaft. At this time, the docking shaft cannot rotate freely, thereby achieving locking; after the contact switch is pressurized, it sends a signal that the docking is in place, and the drive motor is powered off and stops rotating. If the docking is not in place or the docking is accidentally disengaged, the contact switch sends a docking disconnection signal when it is in the reset state to remind the operator.

[0019] Wherein, the end section of the spiral groove of the docking sleeve is provided with parallel sections arranged along the circumferential direction, so as to ensure that the docking sleeve and the docking shaft are not disengaged in the axial direction.

[0020] When separating, pull out the safety lock cap to disengage the lock shaft from the blind hole of the docking shaft to unlock it, and the docking shaft can rotate freely at this time; start the drive motor to make the docking shaft rotate in the opposite direction synchronously, and the protruding pin of the docking shaft moves along the spiral groove trajectory of the docking sleeve, the male connector assembly and the female connector assembly gradually disengage, and the quick male connector and the quick female connector are separated; the spring seat is reset to the bottom of the limit step under the action of the reset spring to cover the through hole and the lock shaft, and after the protruding pin rotates to the opening section of the spiral groove of the docking sleeve, release the safety lock cap and cut off the power to stop the drive motor.

[0021] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention simplifies operation, saves time and effort; improves reliability and safety; requires less reserved installation space; and can timely obtain the docking status of the quick connector. The present invention uses a motor-driven docking mechanism to solve the problem that the mechanical docking structure relies on the handle operation and needs to apply a large torque. At the same time, the structure is more compact and does not require additional installation space, saving time and effort. After the quick connector of the present invention is docked in place, the safety lock can automatically pop out to fix the docking sleeve and the docking shaft, and the end section of the spiral groove is provided with a parallel section along the circumferential direction to prevent the docking sleeve and the docking shaft from axially disengaging, thereby improving the locking reliability of the device. When the locking device of the present invention is correctly connected, the contact switch can send a docking signal under the safety lock shaft. When the docking is not in place or the docking is accidentally disengaged, a warning prompt can be sent to the operator in time to prevent the system from continuing to work when the pipeline pressure loss is high.

[0032] The male connector assembly 1 of the present invention is provided with one or more quick male connectors 12, and the male connector assembly 1 is provided with a group of positioning pins 13; the female connector assembly 2 is provided with one or more quick female connectors 22, and the female connector assembly 2 is provided with a group of guide holes 23 corresponding to the positioning pins 13. One end of the docking shaft 32 of the electric drive device 3 is rigidly connected to the drive motor 31 and can rotate synchronously with the output shaft of the drive motor 31. The other end of the docking shaft 32 is provided with a protruding pin 321, a blind hole 322 and a contact switch 323 installed inside.

[0033] The bottom of the docking sleeve 41 of the docking locking device 4 of the present invention is connected and fixed to the sleeve base 42. The docking sleeve 41 is provided with a spiral groove 411, a through hole 412 and a limit step 413; a spring seat 43 and a return spring 44 are placed between the docking sleeve 41 and the sleeve base 42. The safety lock 45 is installed on the side of the mounting plate where the docking locking device 4 is located, and is used for locking the male connector assembly 1 and the female connector assembly 2 after they are docked in place. The safety lock 45 includes a lock cap 451, a lock sleeve 452, a locking spring 453 and a lock shaft 454. The lock sleeve 45 is fixedly connected to the side hole of the mounting plate where the docking locking device 4 is located. The lock shaft 454 is connected to the lock cap 451 after being inserted into the lock sleeve 452, and the locking spring 453 is located between the lock sleeve 452 and the lock shaft 454.

[0034] The electrically driven multi-way quick connector docking device of the present invention comprises the following steps during docking:

[0035] 1) Positioning before docking: The positioning pin 13 of the male connector assembly 1 is inserted into the guide hole 23 of the female connector assembly 2, and the protruding pin 321 of the docking shaft 32 of the electric drive device 3 is rotated to form a match with the opening section of the spiral groove 411 of the docking sleeve 41 of the docking locking device 4;

[0036] 2) Start docking: Start the drive motor 31 to make the docking shaft 32 rotate synchronously, and the protruding pin 321 of the docking shaft 32 moves along the spiral groove 411 of the docking sleeve 41, gradually pulling the male connector assembly 1 and the female connector assembly 2 to fit each other, and the quick male connector 12 and the quick female connector 22 move toward each other to achieve docking;

[0037] 3) Locking after docking: After the male connector assembly 1 and the female connector assembly 2 are docked, the docking shaft 32 moves axially to compress the spring seat 43 and the return spring 44 to the bottom of the through hole 412 and no longer block the locking shaft 454. Under the action of the locking spring 453, the locking shaft 454 passes through the through hole 412 of the docking sleeve 41 and pops out into the docking shaft blind hole 322. At this time, the docking shaft 32 cannot rotate freely, thereby achieving locking; after the contact switch 323 is pressurized, it sends a signal that the docking is in place, and the drive motor 31 is powered off and stops rotating. If the docking is not in place or the docking is accidentally disconnected, the contact switch 323 sends a docking disconnection signal when it is in the reset state to remind the operator.

[0038] The end section of the spiral groove 411 of the docking sleeve 41 is provided with parallel sections arranged along the circumferential direction, so as to ensure that the docking sleeve 41 and the docking shaft 31 are not disengaged in the axial direction.

[0039] When separating, the safety lock cap 451 is pulled out to disengage the lock shaft 454 from the blind hole 322 of the docking shaft to unlock it. At this time, the docking shaft 32 can rotate freely; the drive motor 31 is started to make the docking shaft 32 rotate in the opposite direction synchronously, and the protruding pin 321 of the docking shaft 32 moves along the trajectory of the spiral groove 411 of the docking sleeve 41, the male connector assembly 1 and the female connector assembly 2 gradually disengage, and the quick male connector 12 and the quick female connector 22 are separated; the spring seat 43 is reset to the bottom of the limit step 413 under the action of the reset spring 44 to block the through hole 412 and the lock shaft 454. After the protruding pin 321 rotates to the opening section of the spiral groove 411 of the docking sleeve 41, the safety lock cap 451 is released and the power is turned off to stop the drive motor 31.

[0040] The present invention is provided with a docking locking mechanism: after the quick connector assembly is docked in place, the spring seat is compressed and no longer blocks the safety lock shaft, and the safety lock can automatically pop out to lock the docking sleeve and the docking shaft. The end section of the spiral groove of the docking sleeve is provided with a parallel section arranged along the circumferential direction to prevent the docking sleeve and the docking shaft from axially disengaging. The present invention is provided with a docking state monitoring mechanism: the safety lock can trigger the contact switch in the locked state to send a docking signal, and the contact switch resets to send a docking disconnection signal when the docking is not in place or the docking is accidentally disengaged, so that the operator can grasp the docking state of the quick connector in time.

[0041] The present invention drives the docking mechanism through a motor, thereby solving the problem that a mechanical docking structure needs to apply a large torque when operated by a handle. At the same time, the structure is more compact and does not require additional installation space, thus saving time and effort. After the quick connector of the present invention is docked in place, the safety lock can automatically pop out to fix the docking sleeve and the docking shaft, and the end section of the spiral groove is provided with a parallel section along the circumferential direction to prevent the docking sleeve and the docking shaft from axially disengaging, thereby improving the locking reliability of the device. When the locking device of the present invention is correctly connected, the contact switch can send a docking signal under the safety lock shaft. When the docking is not in place or the docking is accidentally disengaged, a warning prompt can be sent to the operator in time to prevent the system from continuing to work when the pipeline pressure loss is high.
