[0010] According to at least one embodiment of the coiled tubing equipment and tool disassembly and anti-fall safety device disclosed herein, the blowout riser disassembly and assembly rack is integrally welded to the left side of the downhole tool disassembly and assembly lower frame, three groups of blowout riser bases are fixedly installed on both sides of the bottom of the blowout riser disassembly and assembly rack, and the six groups of blowout riser bases are arranged in a matrix, and blowout riser clamps are fixedly installed on the tops of the blowout riser bases by bolts, and six groups of blowout riser guide holes are opened on the top of the blowout riser disassembly and assembly rack, and the six groups of blowout riser guide holes correspond to the six groups of blowout riser bases one by one, and the tops of the blowout riser clamps are fixedly connected to the corresponding blowout riser guide holes.

[0013] Technical effects and advantages of the utility model:
[0014] By driving the motor, its output shaft drives the worm and the worm wheel to mesh, thereby forcing the high-pressure cylinder fixed to the turntable to rotate. When the high-pressure cylinder rotates, the high-pressure cylinder is driven, so that the downhole tool disassembly and assembly upper frame can deflect upward while moving outward. At the same time, under the action of its own gravity, the downhole tool disassembly and assembly upper frame body can ensure that it is always downward. When the downhole tool disassembly and assembly upper frame moves to the top of the downhole tool disassembly and assembly lower frame, the input of the motor is stopped, and the high-pressure cylinder is retracted at the same time, so that the downhole tool disassembly and assembly upper frame and the downhole tool disassembly and assembly lower frame cooperate, so that the operator can disassemble and assemble the screw motor in the downhole tool disassembly and assembly upper frame. Since the working height is ≥5 meters, it can meet the longest screw motor disassembly and assembly. At the same time, the frame has sufficient strength to avoid the risk of falling and injuring people due to hoisting failure. Since the downhole tool disassembly and assembly upper frame is heavy, a crane is generally used to transport and place the downhole tool disassembly and assembly upper frame. This structure can avoid danger in the process of using a crane to lift the downhole tool disassembly and assembly upper frame;
[0015] Operators can store wellhead flanges on the flange transport platform for transportation. The platform can also store downhole tools and disassemble the upper frame for easy transportation.
[0016] When operators disassemble and assemble the blowout preventer riser in the blowout preventer riser disassembly and assembly rack, the risk of injury caused by the falling of the hoisted objects due to hoisting failure can be avoided. At the same time, the blowout preventer riser clamp on the disassembly and assembly rack can also store the blowout preventer riser for easy transportation;
[0017] Operators can install the pressure test device through the pressure test seat on the blowout preventer platform for pressure testing and other operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 2 It is a transportation diagram of a coiled tubing equipment and a tool disassembly and assembly anti-fall safety device in a transportation state according to one embodiment of the present disclosure.
[0041] Figure 3 It is a working diagram of a coiled tubing equipment and a tool disassembly and assembly anti-fall safety device in a working state according to one embodiment of the present disclosure.
[0042] like Figure 1-Figure 6 As shown, the coiled tubing equipment and tool disassembly and assembly anti-fall safety device disclosed in the present invention may include: a downhole tool disassembly and assembly lower frame 100, a flange transport platform 110, a blowout preventer riser disassembly and assembly frame 120, a blowout preventer platform 130, a foldable escalator 140 and a downhole tool disassembly and assembly upper frame 200 and other components.
[0043] like Figure 3 As shown, in the present disclosure, the continuous tubing equipment and tool disassembly and anti-fall safety device includes a downhole tool disassembly and assembly lower frame 100, a flange transport platform 110, a blowout preventer riser disassembly and assembly frame 120, a blowout preventer platform 130 and a downhole tool disassembly and assembly upper frame 200, wherein the downhole tool disassembly and assembly upper frame 200 is fixedly installed with plug posts 210 at the four corners of the bottom, and the downhole tool disassembly and assembly lower frame 100 is provided with plug holes 101 at the four corners of the top wall, the four groups of the plug posts 210 are respectively used in conjunction with the four groups of plug holes 101, and the downhole tool disassembly and assembly upper frame 200 is plugged into the downhole tool disassembly and assembly lower frame 100, and a foldable escalator 140 is movably installed on the right top wall of the downhole tool disassembly and assembly lower frame 100.
[0044] Thus, through the cooperation between the plug column 210 and the socket 101, the downhole tool disassembly upper frame 200 can be flexibly installed on the downhole tool disassembly lower frame 100, or the downhole tool disassembly upper frame 200 can be disassembled from the downhole tool disassembly lower frame 100, so as to facilitate the transportation or work of the device. At the same time, when the device is in the working state, the foldable escalator 140 can be lowered from the top of the downhole tool disassembly lower frame 100. In particular, the device is a rigid integral structure. According to the function, it can be divided into four parts: a downhole tool disassembly and assembly rack (composed of a downhole tool disassembly and assembly lower frame 100 and a downhole tool disassembly and assembly upper frame 200), a blowout preventer riser disassembly and assembly rack 120, a flange transport platform 110 and a blowout preventer platform 130. The overall dimensions of the device are: 9m long × 2.5m wide × 3.0m high, and the total weight of the device is <13t. The height of the device in the transport state is <3m for easy transportation, and the height in the working state is ≥5m to meet the smooth disassembly and assembly of longer downhole tools, such as a screw motor with L=4.5m.
[0045] like Figure 4 As shown, in the present disclosure, a worm gear 102, a coupling shaft 103, a worm 104, a rotating disk 105, a high-pressure cylinder 106, a rotating rod 107, a grip head 108 and a motor 109 are installed on the side wall of the downhole tool disassembly frame 100, wherein the outer walls on both sides of the downhole tool disassembly frame 100 are rotatably connected to the worm gear 102, and the inner walls on both sides of the downhole tool disassembly frame 100 are rotatably connected to the same coupling shaft 103. The two ends of the connecting shaft 103 are fixedly connected to the two groups of worm gears 102 respectively, a turntable 105 is fixedly installed on the outer wall of the worm gear 102, a high-pressure cylinder 106 is fixedly installed at the center of the turntable 105, a rotating rod 107 is fixedly installed on the output end of the high-pressure cylinder 106, and a grip 108 is fixedly installed on the other end of the rotating rod 107. The outer end wall of the downhole tool disassembly frame 100 is rotatably connected to the same worm 104 on both sides, and the worm 104 is meshed with the worm wheel 102 on this side for use. A motor 109 is fixedly installed on the side wall of the downhole tool disassembly frame 100, and the output end of the motor 109 is fixedly connected to the end wall of the worm 104.
[0046] like Figure 5 As shown, in the present disclosure, the side walls of the downhole tool disassembly and assembly upper frame 200 are provided with lead columns 230, wherein the lead columns 230 are fixedly installed on the outer walls on both sides of the middle part of the downhole tool disassembly and assembly upper frame 200, the two groups of the grip heads 108 are respectively rotatably matched with the two groups of lead columns 230, and the downhole tool disassembly and assembly upper frame 200 is movably connected with the two groups of rotating rods 107.
[0047] Therefore, when the device is required to work, the output shaft of the driving motor 109 drives the worm 104 to mesh with the worm wheel 102, and the two groups of worm wheels 102 rotate synchronously under the action of the connecting shaft 103, so that the worm wheel 102 drives the turntable 105 to rotate, thereby forcing the high-pressure cylinder 106 fixed to the turntable 105 to rotate. When the high-pressure cylinder 106 rotates, the high-pressure cylinder 106 is driven, so that the output end drives the rotating rod 107 to extend outward. Under the cooperation of the grip head 108 and the lead column 230, the rotating rod 107 drives the downhole tool disassembly frame 200 to move outward. Under the action of the high-pressure cylinder 106, The downhole tool disassembly upper frame 200 can deflect upward while moving outward. Since the grip 108 and the lead column 230 can rotate relative to each other, the downhole tool disassembly upper frame 200 can ensure that the downhole tool disassembly upper frame 200 is always downward due to its own gravity. When the downhole tool disassembly upper frame 200 moves to the top of the downhole tool disassembly lower frame 100, the input of the motor 109 is stopped, and the high-pressure cylinder 106 is retracted at the same time, so that the downhole tool disassembly upper frame 200 cooperates with the downhole tool disassembly lower frame 100, so that the device works as shown in the following figure. Figure 3 As shown, in particular, operators can disassemble and assemble the screw motor in the downhole tool disassembly frame 200, with a working height of ≥5 meters, which can meet the requirements of disassembly and assembly of the longest screw motor. At the same time, the frame has sufficient strength to avoid the risk of injuries caused by falling objects due to lifting failure.
[0048] like Figure 6 As shown, in a preferred embodiment, a support frame 111 and a second socket 112 are provided on the flange transport platform 110, wherein the flange transport platform 110 and the right bottom of the downhole tool disassembly and assembly lower frame 100 are integrally welded, support frames 111 are fixedly installed on both sides of the flange transport platform 110, and a second socket 112 is provided at both ends of the support frame 111, the four groups of the plug columns 210 are respectively used in conjunction with the four groups of second sockets 112, and the downhole tool disassembly and assembly upper frame 200 is movably connected to the support frame 111.
[0049] Therefore, the operator can store the wellhead flange on the flange transport platform 110 for transportation, and at the same time, the platform can store the downhole tool disassembly frame 200 for convenient transportation.
[0050] like Figure 6 and Figure 2As shown, in the present disclosure, a blowout riser disassembly and assembly rack 120 is provided with a blowout riser base 121, a blowout riser clamp 122 and a blowout riser guide hole 123, wherein the blowout riser disassembly and assembly rack 120 and the left side of the downhole tool disassembly and assembly lower frame 100 are integrally welded, three groups of blowout riser bases 121 are fixedly installed on both sides of the bottom of the blowout riser disassembly and assembly rack 120, and the six groups of blowout riser bases 121 are arranged in a matrix, and the tops of the blowout riser bases 121 are fixedly installed with blowout riser clamps 122 by bolts, and six groups of blowout riser guide holes 123 are opened on the top of the blowout riser disassembly and assembly rack 120, and the six groups of blowout riser guide holes 123 correspond to the six groups of blowout riser bases 121 respectively, and the tops of the blowout riser clamps 122 are fixedly connected with the corresponding blowout riser guide holes 123.
[0051] Therefore, when operators disassemble and assemble the blowout preventer riser in the blowout preventer riser disassembly and assembly rack 120, the risk of injury from falling objects due to lifting failure can be avoided. At the same time, the blowout preventer riser clamp 122 on the disassembly and assembly rack can also store the blowout preventer riser for easy transportation.
[0052] like Figure 1 and Figure 6 As shown, in a preferred embodiment, a pressure test seat 131 is provided on the blowout preventer platform 130, wherein the blowout preventer platform 130 and the left bottom of the blowout preventer riser disassembly and assembly frame 120 are integrally welded, and the pressure test seat 131 is fixedly installed on the top wall of the blowout preventer platform 130.
[0053] Thus, the operator can install the pressure test device on the BOP platform 130 through the pressure test seat 131 for pressure testing and other operations.
[0054] like Figure 5 As shown, in a preferred embodiment, a climbing ladder 220 is provided on the downhole tool disassembly upper frame 200 , wherein a climbing ladder 220 is provided in the middle of one side of the downhole tool disassembly upper frame 200 .
[0055] Therefore, the operator can move on the downhole tool disassembly and assembly upper frame 200 through the climbing ladder 220. At the same time, the climbing ladder 220 can ensure the safety of the operator when disassembling and assembling the screw motor in the downhole tool disassembly and assembly upper frame 200.
