Description

Technical Field

[0001] The utility model relates to the field of connection devices, in particular to a remotely operated and quickly separated decoupling connection device. Background Art

[0002] Various industries are developing rapidly today, and more high-risk working conditions have also been generated, such as mining, high-risk chemicals, and oil and gas industries. The working areas of these high-risk working conditions are usually environments that are difficult for people to access, so remote maintenance operations are often required after equipment failures to send the required equipment in / out of the working area, and quickly separate them for repair or replacement. In the prior art, electromagnets are usually used to adsorb equipment to move in and out of the working area, but the electromagnetic adsorption method has certain instability, and some special equipment is prone to failure after being affected by electromagnetics, resulting in inability to work normally, and the engineering conditions required for electromagnetic adsorption and separation are relatively complex, which will increase the infrastructure burden of the working area. Utility Model Content

[0003] The utility model is intended to provide a remotely operated, quickly detachable unhooking connection device to solve the problem in the prior art that equipment in high-risk working areas is repaired or replaced by electromagnetic adsorption, which has certain instability and affects the working performance of some equipment.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a remotely operated, quickly separated unhooking connection device, comprising a connecting rod, the top end of the connecting rod is a connecting end, an adjusting sleeve is threadedly connected to the connecting rod below the connecting end, the adjusting sleeve is connected to an operating rod, a locking seat is sleeved on the connecting rod below the adjusting sleeve, an annular groove is circumferentially provided on the inner wall of the locking seat, a support seat is provided at the bottom of the connecting rod, an elastic support member is provided between the support seat and the locking seat, a connecting cavity extending into the interior of the connecting rod is provided in the middle of the support seat, a plurality of tapered holes with small ends facing inward are evenly distributed on the side wall of the connecting cavity along the circumferential direction, a locking steel ball is provided in the tapered hole, and the diameter of the locking steel ball is larger than the minor diameter and length of the tapered hole.

[0005] Preferably, as an improvement, four insertion holes are evenly distributed around the lower part of the adjustment sleeve, and the operating rod is inserted into the insertion holes transversely, and the operating rod is L-shaped.

[0006] Preferably, as an improvement, there are four tapered holes and four locking steel balls.

[0007] Preferably, as an improvement, the locking seat includes a seat body and a sleeve, the seat body is in a stepped cylindrical shape, an annular groove is opened on the inner wall of the seat body, the top of the sleeve is against the step surface of the seat body, and the lower part of the sleeve is sleeved on the outer side of the support seat.

[0008] Preferably, as an improvement, the elastic support member is a spring, a support step is provided on the seat body inside the sleeve, the top end of the spring abuts against the support step, and the bottom end of the spring abuts against the support seat.

[0009] Preferably, as an improvement, an external thread is provided on the connecting end, and the thread rotation direction of the connecting end is opposite to the thread rotation direction of the connecting adjustment sleeve.

[0010] The principle and advantage of this scheme are: in actual application, the connecting end of the connecting rod is threadedly connected to the partition between the working area and the non-working area, and the connecting device of this scheme is moved to the top of the equipment to be operated in the working area. In the non-working area, a long rod is used to toggle the operating rod to rotate the adjustment sleeve to achieve lifting and lowering. The adjusting sleeve is lowered to press the locking seat down, so that the locking steel ball moves from the tapered hole to the annular chute, and the locking steel ball is located outside the connecting cavity. The moving connecting device is lowered to cover the connecting cavity on the rod-shaped protruding structure on the top of the equipment, and then the long rod is operated to toggle the operating rod to make the adjusting sleeve rise, and the spring pushes the locking seat upward, and the locking steel ball is squeezed from the annular chute into the tapered hole. Due to the size design of the locking steel ball, the locking steel ball is squeezed by the inner wall of the seat body and partially enters the connecting cavity. The four locking steel balls enter the connecting cavity to clamp the equipment, so that the lower equipment is connected with the upper equipment, and then the lower equipment is transferred to the non-working area with the connecting device of this scheme for maintenance or replacement. When replacing, the new equipment can be placed in the working area by reverse operation. This solution uses a purely mechanical connection to avoid electromagnetic instability and the problem that some special equipment cannot work properly after being affected by electromagnetics. The connection of this device is stable and reliable, and can achieve multiple stable connections and separations. At the same time, it also meets the load requirements after connection. According to the design requirements, it can withstand a load of up to 2000Kg, which can be used under some special conditions, and supplements the remote separation and connection functions in some scenarios where electromagnetics cannot be applied. The thread rotation direction of the connection end is opposite to the thread rotation direction of the connection adjustment sleeve, which ensures that the connection end can still be stably connected to the upper device during the process of toggling the operating lever. The spring provides stability for the entire device. Through the upward support force of the spring, it avoids the loosening of the nut and the accidental disengagement of the connection device due to various unexpected mechanical vibrations in the working area and natural factors such as earthquakes and wind, which further ensures the stability of the device.
