DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1-5As shown, the present invention is an oil drilling rig plug-in and transfer room with a telescopic track type cable retracting and releasing device, comprising an plug-in and transfer room body 1, wherein lifting bars 18 are symmetrically provided at the four corners of the outer periphery of the plug-in and transfer room body 1, and a sliding mechanism, a telescopic mechanism and a winding mechanism are provided inside the plug-in and transfer room body 1; lateral support rails 15 are symmetrically provided on both sides of the inner wall of the plug-in and transfer room body 1 along the sliding direction of the sliding mechanism, and a plurality of modular holes 25 are equidistantly provided on the lateral support rails 15 as positioning holes 25; a slide plate 20 is rotatably connected to one side of the bottom of the plug-in and transfer room body 1 along the sliding direction of the sliding mechanism, and lock buckles are provided on the plug-in and transfer room body 1 at both ends of the slide plate 20. When the slide plate 20 is needed for extension, the lock buckle is unlocked and the slide plate 20 is lowered. When the slide plate 20 is not needed for retraction, the lock buckle is locked to fix the slide plate 20 to the outer wall of the plug-in and transfer room body 1.

[0018] The sliding mechanism includes a first slide rail 21 arranged at the bottom of the plug-in and transfer room body 1 and a second slide rail 11 arranged at the top of the plug-in and transfer room body 1; a telescopic mechanism is slidably connected to the first slide rail 21, and a first stopper 6 and a second stopper 12 are respectively provided on the top of the first slide rail 21 at both ends of the telescopic mechanism; a winding mechanism is slidably connected to the second slide rail 11.

[0019] The telescopic mechanism includes a mobile frame 26, and a cable placement rack 2 is arranged inside the mobile frame 26. The cable placement rack 2 includes four layers of wire storage plates 22 arranged in parallel with each other. Four vertical winding posts 4 are symmetrically arranged in the mobile frame 26 at both ends of the wire storage plates 22, and each winding post 4 is provided with four winding hubs 23; in particular, the number of wire storage plates 22 and winding hubs 23 is the same, and they correspond one by one from top to bottom. In order to make it suitable for the storage and release of cables of different specifications, the layer height of the wire storage plate 22 and the height of the winding hub 23 are adjustable. When in use, the height can be adjusted according to needs to meet the needs of cables in different scenarios, and the corresponding installation height of the winding hub 23 is greater than the installation height of the wire storage plate 22 to avoid cables piling up and dragging on the ground. A group of driving rollers 5 with a motor and three groups of driven rollers 3 are connected to the bottom of the cable placement rack 2, and the driven rollers 3 are connected to the bottom of the mobile frame 26 by telescopic rods 24. The plug-in room body 1 at both ends of the slide 20 is as shown in FIG. Figure 5The lock buckle 27 shown in the figure comprises two connecting plates 28 respectively fixed on the plug-in and transfer room body 1 and the slide 20. The connecting plate 28 on the slide 20 is provided with a lock hole 29 with an opening on one side. The connecting plate 28 on the plug-in and transfer room body 1 is rotatably connected with an insert rod 30 for inserting into the lock hole 29 for locking. When the telescopic mechanism slowly extends out of the plug-in and transfer room body 1, the insert rod 30 is rotated to remove the insert rod 30 from the open side of the lock hole 29, and then the lock buckle 27 is unlocked, the slide 20 is lowered, and the motor of the driving roller 5 is started to rotate forward to drive the driven roller 3 to slide along the first slide rail 21 to the slide 20 under the action of its own weight, and then the telescopic rod 24 is gradually lengthened through the sliding of the slide 20, so that the driven roller 3 contacts the ground 7 until the extension length requirement is met; when the telescopic mechanism retracts to the plug-in and transfer room body 1, the motor of the driving roller 5 is started to rotate reversely to drive the driven roller 3 to slide from the slide 20 to the first slide rail 21. During the sliding process, the telescopic rod 24 moves in the reverse direction of the slide 20. Under the action of force, it gradually retracts until the driven roller 3 drives the telescopic mechanism to retract completely into the insertion and rotation room body 1, and then the insertion rod 30 is rotated to insert the insertion rod 30 from the open side of the lock hole 29, and then the lock buckle 27 is locked to fix the slide 20 on the outer wall of the insertion and rotation room body 1 for next use; the telescopic mechanism also includes a slider 13 arranged on the cross-bracing slide rail 15, and the slider 13 is inserted with an M18 bolt as a positioning column 14, and the slider 13 can slide along the cross-bracing slide rail 15 to realize the movement of the telescopic mechanism, and then the positioning column 14 inserted into the positioning hole 25 is used for limiting and fixing, so as to realize the limiting and fixing of the telescopic mechanism at different positions.

[0020] The winding mechanism includes three sets of fixed pulley winding discs 9 and three sets of sliding pulley winding discs 10 which are symmetrically arranged on the top of the plug-in room body 1 along the sliding direction of the sliding mechanism and connected by high-strength chains 17. The sliding pulley winding disc 10 can move left and right along the second slide rail 11. The traction part above the sliding pulley winding disc 10 is connected to the movable frame 26, and the length of the cable between the fixed pulley winding disc 9 and the sliding pulley winding disc 10 is greater than the length of the chain 17. The chain 17 is used to protect the cable when it is stretched.

[0021] Cables are hung on the periphery of the fixed pulley winding disc 9 and the sliding pulley winding disc 10, and the cables include power cables 8 and control cables 19. The power cables 8 and the control cables 19 are separately hung on the fixed pulley winding disc 9, the sliding pulley winding disc 10 and the cable placement rack 2. Specifically, the control cables 19 are few in number and thin in diameter, and are hung on the fixed pulley winding disc 9 and the sliding pulley winding disc 10 in the middle, and are coiled and stored on the winding hubs 23 and the cable placement rack 2 on the upper two layers. The power cables 8 are numerous in number and thick in diameter. In order to maintain the overall balance of the plug-in room body 1, the cables are laid from both sides and hung on the fixed pulley winding disc 9 and the sliding pulley winding disc 10 on both sides, and are coiled and stored on the winding hubs 23 and the cable placement rack 2 on the lower two layers.

[0022] A lifting baffle 16 is provided at the oil drilling site. When in use, the lifting belt is wound around the lifting bar 18 and located on the inner side of the lifting baffle 16, and then the plug-in and transfer room is lifted to the use position, and then the power cable 8 and the control cable 19 are pulled out on the cable placement rack 2 according to the required length of the cable. When the cable length on the cable placement rack 2 is insufficient, the second block 12 is removed, the motor of the driving roller 5 is started to rotate forward, and the driving roller 5 moves and drives the driven roller 3 to start moving along the first slide rail 21 to the outside of the plug-in and transfer room body 1. As the telescopic mechanism continues to extend, the driven roller 3 slides along the first slide rail 21 to the slide plate 20 under the action of its own weight, and then the slide plate 20 slides and gradually lengthens the telescopic rod 24, so that the driven roller 3 contacts the ground 7 until the extended length requirement is met. During the extension process, the sliding pulley winding disc 10 slides along the first slide rail 11 driven by the telescopic mechanism, and then the cable between the fixed pulley winding disc 9 and the sliding pulley winding disc 10 is gradually lengthened. During the entire telescopic process, the positioning column 14 on the slider 13 is extended into the positioning hole 25 of the cross-bracing slide rail 15 to achieve the limit and fixation of different positions of the telescopic mechanism. When the telescopic mechanism is extended to the maximum stroke, the chain 17 is straightened, and the cable of the telescopic mechanism is extended to the maximum, and the plug-in room is extended from 6m to 9.5m.

[0023] After the cables are used, the cables of the cable rack 2 are first stored in order through the winding column 4, and then the positioning column 14 is taken out from the slider 13 and the cross-bracing slide rail 15, and the motor of the driving roller 5 is started to reverse and drive the driven roller 3 to slide from the slide plate 20 to the first slide rail 21. During the sliding process, the telescopic rod 24 gradually retracts under the action of the reaction force of the slide plate 20 until the driven roller 3 drives the telescopic mechanism to retract completely into the plug-in and transfer room body 1, and then the lock buckle is locked to fix the slide plate 20 to the outer wall of the plug-in and transfer room body 1 for next use. During the retraction process, the sliding pulley winding disc 10 retracts together with the telescopic mechanism. When the distance between the fixed pulley winding disc 9 and the sliding pulley winding disc 10 is reduced to the set safety distance, the cable between the two gradually resumes the hanging state. When the telescopic mechanism retracts to the position of the first stop block 6, the second stop block 12 is inserted back to its original position, and then the positioning column 14 is inserted into the positioning hole 25 of the slider 13 and the cross-bracing slide rail 15 for positioning to prevent the telescopic mechanism from sliding out at will.
