Description

Technical Field

[0001] The present invention relates to the field of vertical shaft installation and construction, and in particular to an overall line stabilization auxiliary device for vertical shaft equipment installation and an auxiliary method thereof. Background Art

[0002] During the installation and construction of vertical shaft equipment, in order to accurately install the irrigation beams, pipelines, etc., before construction, it is necessary to use a large line vehicle to lay several large lines from the ground sealing plate to the lower wellhead of the shaft according to the design requirements, and fix the large lines on the stabilizing beams at the lower wellhead as the vertical reference lines for the installation of shaft equipment.

[0003] Shaft stabilization (also called shaft guidance or shaft stabilization) is an important technical measure in mine construction. Its main purpose is to ensure that the shaft remains straight and vertical during excavation and support, thereby improving the quality and safety of the shaft.

[0004] The prior art discloses some invention patents for vertical shaft installation and construction. The Chinese patent with application number 201920403231.5 discloses an overall line stabilization auxiliary device for vertical shaft equipment installation, which is characterized by: comprising a line stabilization frame, which is composed of a plurality of line stabilization steel pipes that cooperate with each other, the length of the line stabilization steel pipe is greater than the spacing between two adjacent large lines, and the two ends of the line stabilization steel pipe are respectively provided with clamping grooves corresponding to the positions of adjacent large lines, the ends of the adjacent line stabilization steel pipes are staggered and superimposed up and down, and the clamping grooves at both ends are respectively used to clamp the corresponding large lines, and the two adjacent line stabilization steel pipes are fixed together with the large lines by wire bundling.

[0005] In the traditional line-laying process, after the construction workers place the stabilizing wires downwards, they need to wait for the stabilizing wires to stabilize one by one before fixing them on the stabilizing wire beams in the wellbore. However, the existence of airflow in the wellbore is unavoidable. Under the action of the airflow, the stabilizing wires will shake and become difficult to stabilize. The deeper the wellbore, the more obvious the shaking of the stabilizing wires will be, resulting in the inability to align the stabilizing wires up and down, thus affecting construction efficiency. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose an overall line stabilization auxiliary device and an auxiliary method for installing shaft equipment in a vertical shaft.

[0007] In a first aspect, the present invention provides an integral line stabilization auxiliary device for installing shaft equipment, comprising a top bracket, wherein the top bracket is composed of four first square rods arranged in a frame shape, and further comprising:

[0008] Four first sliding frames are respectively arranged between four intersections of the four first square rods, and both ends of the first square rods are slidably connected to adjacent first sliding frames;

[0009] A bottom bracket, the bottom bracket also consists of four second square rods arranged in a frame shape;

[0010] Four second sliding frames are respectively arranged between four intersections of the four second square rods, and both ends of the second square rods are slidably connected to adjacent first sliding frames;

[0011] A synchronous adjustment component, installed between the bottom bracket and the top bracket, used for synchronously adjusting the bottom bracket and the square rods at corresponding positions in the top bracket to move synchronously for adjustment;

[0012] A self-drop assembly is installed between the first sliding frame and the second sliding frame, a stabilizing wire passes through the self-drop assembly, and a lowering speed of the bottom bracket is automatically controlled by controlling a release rate of the stabilizing wire;

[0013] After the device is installed at the wellbore opening, when the stabilizing wire needs to be arranged, the staff passes the stabilizing wire through the self-drop assembly, so that the four stabilizing wires that need to be arranged are arranged at the four corners of the first sliding frame after the self-drop assembly is installed, thereby completing the preliminary positioning of the stabilizing wire;

[0014] Then, according to the inner diameter of the wellbore, the staff can push the first sliding frame to move on the first square rod of the top bracket, and the movement of the first sliding frame can drive the movement of the stabilizing line, thereby driving the stabilizing line to move on the first square rod for position adjustment;

[0015] The first square rod of the top bracket is connected to the second square rod of the bottom bracket through a synchronous adjustment component, and the first sliding frame is connected to the second sliding frame through a synchronous adjustment component, so that when the stabilizing wire moves on the first square rod through the first sliding frame, the stabilizing wire passing through the bottom bracket is synchronously moved on the second square rod through the second sliding frame, so that the positions of the stabilizing wire on the top bracket and the bottom bracket are synchronously moved and vertically aligned, so that when the stabilizing wire is lowered, the stabilizing wire can be vertically aligned by aligning the top bracket and the bottom bracket, which is conducive to positioning the stabilizing wire when it is arranged;

[0016] After the adjustment of the stabilizing line is completed, the staff starts the self-dropping assembly, which can control the bottom of the bottom bracket so that the bottom bracket drives the stabilizing line to move downward. The frame structure of the bottom bracket is basically in contact with the inner wall of the wellbore, so that the bottom bracket will not produce violent shaking inside the wellbore during the process of being below, which is conducive to reducing the occurrence of strong shaking of the stabilizing line due to the airflow inside the wellbore during the process of being below, thereby helping to reduce the shaking of the stabilizing line and improving the efficiency of arranging the stabilizing line;

[0017] After the lowering is completed, the bottom bracket is fixed on the line stabilizing frame at the bottom of the wellbore, thereby fixing the stabilizing line.

[0018] Preferably, the synchronous adjustment component comprises:

[0019] A plurality of straight rods, two of the straight rods form a group, one second square rod corresponds to a group of straight rods, the two straight rods in the same group are symmetrically fixed to the tops of both ends of the corresponding second square rods, the first square rods are vertically aligned with the second square rods one by one, and the tops of the straight rods at both ends of the second square rods penetrate the corresponding first square rods and are vertically slidably connected;

[0020] A positioning assembly, the positioning assembly comprising an upper positioning member installed at the bottom of the first sliding frame and a lower positioning member installed at the top of the second sliding frame, and used for driving the first sliding frame and the second sliding frame to move synchronously when the upper positioning member matches the lower positioning member;

[0021] The bottom of the straight rod is fixed to the second square rod of the bottom bracket, and the top of the straight rod is fixed to the first square rod of the top bracket, so that the first square rod and the second square rod can be relatively fixed under the action of the straight rod, so that when the first sliding frame and the second sliding frame drive the stabilizing line to move synchronously under the locking action of the locking assembly, the two moving points of the stabilizing line can be vertically aligned on the first square rod and the second square rod, which is beneficial to the alignment of the stabilizing line.

[0022] Preferably, it also includes:

[0023] A plurality of groups of intermediate sliding frames, four of which form a group, each group of intermediate sliding frames being arranged in a vertical array, each group of intermediate sliding frames being connected by a clamping assembly, and the top of the top intermediate sliding frame being provided with the lower clamping member, and the bottom of the bottom intermediate sliding frame being provided with an upper clamping member;

[0024] Multiple groups of intermediate brackets, each group of intermediate brackets is arranged in a vertical array and is arranged corresponding to each group of intermediate sliding brackets, and the intermediate brackets in the same group are composed of four third-party rods, and the four third-party rods are slidably connected at the ends through the corresponding group of intermediate sliding brackets to form a frame;

[0025] Both ends of all the third-party rods are penetrated with limiting holes adapted to be plugged into the straight rods;

[0026] When the bottom bracket starts to move downward, all the intermediate sliding frames are connected to the second sliding frame at the bottom through the locking assembly, so that all the intermediate frames move downward synchronously with the bottom bracket. After a certain height below the bottom bracket, the locking assembly connected to the intermediate sliding frame at the top at this time cancels the locking action, so that the locking effect between the top intermediate sliding frame and the second intermediate sliding frame is cancelled, thereby causing the top intermediate sliding frame to separate from the combination of the lowered bottom bracket and the remaining intermediate sliding frames. At this time, due to the insufficient weight of the intermediate sliding frame and the intermediate bracket connected thereto, it is not enough to overcome the friction between the stabilizing line and the self-landing assembly, so that the intermediate sliding frame and the intermediate bracket connected thereto remain in the middle of the wellbore. Since the shape of the intermediate bracket matches the inner diameter of the wellbore, the four corners of the intermediate bracket are against the inner wall of the wellbore, so that the intermediate bracket will not produce a large range of shaking inside the wellbore, thereby positioning the stabilizing line in the middle position, which is beneficial to avoid the situation where the stabilizing line is difficult to maintain stability when the wellbore depth increases, thereby improving the efficiency of the stabilizing line arrangement.

[0027] Preferably, the upper positioning member comprises:

[0028] Four first sliding grooves are respectively provided at the bottom of the four first sliding frames or the middle sliding frames;

[0029] Four groups of limit sliders, two of which form a group, the four groups of limit sliders are symmetrically slidably installed inside the four limit sliders, and ordinary magnets are fixed inside all the limit sliders;

[0030] The lower clamping member comprises:

[0031] Four card slots are respectively provided on the tops of the four second sliding frames or the middle sliding frames;

[0032] The bottoms of the four groups of limit sliding blocks are respectively matched with the four card slots;

[0033] Four groups of first electromagnets, two of the first electromagnets form a group, and the four groups of the first electromagnets are symmetrically fixed on both sides of the four card slots;

[0034] Four second electromagnets are respectively fixed at the centers of the four card slots;

[0035] When the upper locking member matches the lower locking member, that is, when the bottom of the limit slider is inserted into the corresponding slot, since the limit slider is set in an L shape, after the bottom horizontal plate of the limit slider is inserted into the bottom slot, under the action of the vertical force, the limit slider cannot be pulled out of the slot, thereby achieving the locking effect;

[0036] When the first electromagnet and the second electromagnet are energized and started, the first electromagnet generates a repulsive force with the same poles on the ordinary magnet, and the second electromagnet generates an attractive force with different poles on the ordinary magnet, a pushing force can be generated on the limit slider, so that the bottom cross plate part of the limit slider is inserted into the interior of the slot, thereby realizing the locking effect. After the first electromagnet and the second electromagnet are energized and started in the reverse direction, the first electromagnet generates an attractive force with different poles on the ordinary magnet, and the second electromagnet generates a repulsive force with the same poles on the ordinary magnet, a reverse pushing effect can be generated on the limit slider, thereby pushing the bottom cross plate part of the limit slider out of the interior of the slot, so that under the action of the vertical force, the limit slider can be pushed out of the slot to cancel the locking effect.

[0037] Preferably, the self-landing assembly comprises:

[0038] A plurality of positioning frames, wherein a positioning frame is fixed on the side walls of all the first sliding frames, the second sliding frames, and the middle sliding frames, and the first sliding frames and the second sliding frames that are vertically aligned, and the positioning frames fixed on the middle sliding frames are vertically aligned and form a group;

[0039] Multiple turning frames, one turning frame is rotatably mounted on the side wall of all the positioning frames, the turning frames are connected to the corresponding positioning frames through positioning pieces, and a straight groove is vertically penetrated between the turning frames and the corresponding positioning frames;

[0040] The stabilizing wire passes through the inside of the straight groove, and there is friction between the stabilizing wire and the straight groove, so that the falling of the bottom bracket is hindered by the friction, thereby slowing down the falling speed of the bottom bracket, and preventing the rapid falling of the bottom bracket from causing the arrangement of the stabilizing wire to lose control;

[0041] The flip frame can flip open after the positioning of the positioning piece is released, so that it is convenient to put the stabilizing wire into the straight groove, which is conducive to the installation of the stabilizing wire. After the stabilizing wire passes through the straight groove and is installed, the flip frame and the positioning frame are positioned by the positioning piece, which is conducive to avoiding the stabilizing wire from leaving the straight groove and losing the positioning function.

[0042] Preferably, the self-landing assembly further comprises:

[0043] Four fixing frames, respectively fixed to the bottoms of the four second sliding frames;

[0044] Four first pulleys are rotatably mounted inside the four fixing frames respectively;

[0045] Four lifting frames are respectively mounted on the side walls of the fixed frame in a vertically slidable manner;

[0046] The four second pulleys are rotatably mounted inside the four lifting frames respectively;

[0047] Four cylinders are respectively fixed on the side walls of the four lifting frames, and the tops of the telescopic rods of the four cylinders are fixed with fixing plates, and the four fixing plates are respectively fixedly connected to the four fixing frames;

[0048] Four motors, respectively fixed on the side walls of the four lifting frames, for driving the corresponding second pulleys to rotate;

[0049] After the motor is started, it can drive the corresponding second pulley to rotate through the output shaft. After the cylinder is started, it can drive the fixed plate to move through the telescopic rod. The fixed plate is fixedly connected to the fixed frame, and the cylinder is fixed on the side wall of the lifting frame. The distance between the fixed frame and the lifting frame is adjusted by starting the cylinder, thereby adjusting the distance between the first pulley and the second pulley, so that when the distance between the first pulley and the second pulley is reduced, the squeezing of the stabilizing line can be increased, thereby achieving fixation of the stabilizing line by increasing the squeezing force on the stabilizing line. After the stabilizing line is fixed by increasing the squeezing, the motor drives the second pulley to rotate, and the stabilizing line can be adjusted to release and reel in the stabilizing line through the rotation of the second pulley, thereby adjusting the position of the bottom bracket in the wellbore, and the lower speed of the wellbore can be adjusted, thereby adjusting the lower speed of the stabilizing line.

[0050] Preferably, it also includes:

[0051] A plurality of second slide grooves are arranged corresponding to the intermediate brackets one by one, are opened inside the corresponding intermediate brackets, and have two ends passing through the intermediate brackets;

[0052] A plurality of electric push rods, two of the electric push rods form a group, the two electric push rods in the same group are symmetrically fixed inside one of the second slide slots, and the electric push rods in the same group are arranged in back-to-back orientation;

[0053] A plurality of locking rods are arranged corresponding to the electric push rods one by one and fixed to the ends of the telescopic rods of the corresponding electric push rods;

[0054] After the electric push rod is started, it can push the connected locking rod to move through the telescopic rod. When the middle sliding frame and the middle bracket are separated from the bottom bracket, the limiting holes at both ends of the third rod of the middle bracket are no longer blocked by the straight rod passing through, so that the locking rod can be extended from the end of the second slide groove under the pushing action of the electric push rod, so that the locking rod extended at the end can extend the length of the third rod, so that the locking rod can fit more closely against the inner wall of the wellbore, so that the middle bracket has no room to shake inside the wellbore, thereby positioning the middle bracket and positioning the stabilizing line, so that the middle part of the stabilizing line is positioned and restricted, which is conducive to avoiding severe shaking of the middle part of the stabilizing line.

[0055] Preferably, the positioning member comprises:

[0056] A plurality of limiting balls are fixed on the side wall of the flip frame in a vertical array;

[0057] A plurality of limiting grooves are provided on the side wall of the positioning frame and are plugged and matched with the limiting balls;

[0058] The limiting ball is made of flexible rubber. When the limiting ball is inserted into the limiting groove, the limiting ball is stuck in the limiting groove and will not fall out due to the matching limiting ball inside the limiting groove until the limiting ball is pulled by an external force, causing the limiting ball to deform itself under the action of the rigid force, thereby falling out from the inside of the limiting groove, which is beneficial to the positioning between the positioning frame and the flip frame.

[0059] Preferably, it also includes:

[0060] A plurality of ray lamps are respectively fixed to the bottom of all the turning frames except the top turning frame;

[0061] A plurality of receivers, respectively fixed on the top of all the turning frames except the bottom turning frame, and the receivers are used to receive the radiation from the radiation lamp;

[0062] The ray lamp emits rays downward, and when the first sliding frame is aligned with the second sliding frame and the middle sliding frame, that is, when all positions of the stable line are aligned, the rays emitted downward by the ray lamp are received by the receiver, which means that all positions of the stable line are aligned and the stable line is in a vertical state. Therefore, the state of the stable line can be detected, which is helpful to avoid the stable line from shaking under the action of airflow and affecting the reference to the wellbore.

[0063] In a second aspect, an auxiliary method for installing an integral line stabilization auxiliary device for vertical shaft equipment is provided, wherein a control unit is installed on the top bracket, the control unit includes a user end, and the positioning components are numbered in sequence from top to bottom, the auxiliary method includes the following steps:

[0064] The control unit obtains landing distance information h from the self-landing component;

[0065] The control unit obtains the landing distance information H from the user terminal;

[0066] The control unit substitutes the landing distance information h and the landing spacing information H into a judgment formula h=nH, wherein n is any positive integer. If the judgment formula is satisfied, the control unit generates separation control information and stores the value of n that satisfies the judgment formula as N;

[0067] The control unit sends separation control information to the blocking component numbered N to control the corresponding blocking component to cancel the blocking;

[0068] When the self-landing assembly falls, the falling distance can be recorded, that is, the number of rotations of the output shaft of the motor is recorded, so as to calculate the edge rolling distance of the second pulley, thereby recording the falling distance and forming the falling distance information h. Then, the self-landing assembly sends the falling distance information h to the control unit, so that the control unit obtains the falling distance information h.

[0069] The staff can input the drop distance information H through the user terminal, where the drop distance information H is the distance between the adjacent intermediate sliding frames to be arranged, so that the control unit can obtain the drop distance information H from the user terminal;

[0070] The control unit then substitutes the landing distance information h and the landing spacing information H into the judgment formula h=nH, and then sequentially substitutes n=, n=, n=... to perform judgment on the judgment formula. When the judgment formula is met, for example, when n=, the judgment formula is met, the control unit generates separation control information, and the control unit stores N=n=. The control unit then sends the separation control information to the positioning component numbered, and the controller cancels the positioning, so that the middle sliding frame above the positioning component numbered is disengaged, thereby realizing the separation and release of the middle sliding frame at each interval, so that the stable line is positioned at each interval, which is beneficial to slow down the shaking of the stable line.

[0071] Compared with the prior art, the present invention has the following beneficial effects:

[0072] 1. The present invention arranges a synchronous adjustment assembly and a self-drop assembly so that when the stabilizing line is lowered, the stabilizing line can be vertically aligned by aligning the top bracket with the bottom bracket, thereby facilitating the positioning of the stabilizing line when the stabilizing line is arranged.

[0073] 2. The present invention positions the stabilizing line at an intermediate position by setting an intermediate support, which helps to avoid the situation where the stabilizing line is difficult to maintain stability because only the two ends are fixed when the depth of the wellbore increases, thereby improving the efficiency of the stabilizing line arrangement.

DETAILED DESCRIPTION

[0084] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0085] like Figures 1 to 9 The vertical shaft equipment installation integral line stabilization auxiliary device shown includes a top bracket 2, the top bracket 2 is composed of four first square rods arranged in a frame shape, and also includes:

[0086] Four first sliding frames 201 are respectively arranged between four intersections of the four first square rods, and both ends of the first square rods are slidably connected to adjacent first sliding frames 201;

[0087] The bottom bracket 3 is also composed of four second square rods arranged in a frame shape;

[0088] Four second sliding frames 301 are respectively arranged between four intersections of the four second square rods, and both ends of the second square rods are slidably connected to the adjacent first sliding frames 201;

[0089] A synchronous adjustment component is installed between the bottom bracket 3 and the top bracket 2, and is used to synchronously adjust the square rods at corresponding positions of the bottom bracket 3 and the top bracket 2 to move synchronously for adjustment;

[0090] A self-drop assembly is installed between the first sliding frame 201 and the second sliding frame 301. The stabilizing wire passes through the self-drop assembly. The lowering speed of the bottom bracket 3 is automatically controlled by controlling the release rate of the stabilizing wire.

[0091] In the traditional wire laying process, after the construction workers place the stabilizing wires downward, they need to wait for the stabilizing wires to stabilize one by one before fixing them on the stabilizing wire beams in the shaft. However, there is inevitably airflow in the shaft. Under the action of the airflow, the stabilizing wires will shake and become difficult to stabilize. The deeper the shaft, the more obvious the shaking of the stabilizing wires is, which makes it impossible to align the stabilizing wires up and down, thus affecting the construction efficiency.

[0092] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: after the device is installed at the opening of the wellbore 1, when the stabilizing line needs to be arranged, the staff passes the stabilizing line through the self-drop assembly, so that the four stabilizing lines that need to be arranged are arranged at the four corners of the position of the first sliding frame 201 after being installed through the self-drop assembly, thereby completing the preliminary positioning of the stabilizing line;

[0093] Then, according to the inner diameter of the wellbore 1, the staff can push the first sliding frame 201 to move on the first square rod of the top bracket 2. The movement of the first sliding frame 201 can drive the movement of the stabilizing line, thereby driving the stabilizing line to move on the first square rod for position adjustment;

[0094] The first square rod of the top bracket 2 is connected to the second square rod of the bottom bracket 3 by a synchronous adjustment component, and the first sliding frame 201 is connected to the second sliding frame 301 by a synchronous adjustment component, so that when the stabilizing line moves on the first square rod through the first sliding frame 201, the stabilizing line passing through the bottom bracket 3 is synchronously moved on the second square rod through the second sliding frame 301, so that the positions of the stabilizing line on the top bracket 2 and the bottom bracket 3 are synchronously moved and vertically aligned, so that when the stabilizing line is lowered, the stabilizing line can be vertically aligned by aligning the top bracket 2 and the bottom bracket 3, which is conducive to positioning the stabilizing line when the stabilizing line is arranged;

[0095] After the adjustment of the stabilizing line is completed, the staff starts the self-dropping assembly, which can control the bottom of the bottom bracket 3, so that the bottom bracket 3 drives the stabilizing line to move downward to move the stabilizing line downward. The frame structure of the bottom bracket 3 is basically in contact with the inner wall of the wellbore 1, so that the bottom bracket 3 will not produce violent shaking inside the wellbore 1 during the downward process, which is conducive to reducing the occurrence of strong shaking of the stabilizing line due to the airflow inside the wellbore 1 during the downward process, thereby helping to reduce the shaking of the stabilizing line and improving the efficiency of the stabilizing line arrangement;

[0096] After the lowering is completed, the bottom bracket 3 is fixed on the line stabilizing frame at the bottom of the wellbore 1, so as to achieve the fixation of the line stabilizing frame.

[0097] As an optional embodiment, the synchronization adjustment component includes:

[0098] A plurality of straight rods 11, two straight rods 11 form a group, one second square rod corresponds to one group of straight rods 11, the two straight rods 11 in the same group are symmetrically fixed to the tops of both ends of the corresponding second square rods, the first square rod and the second square rod are vertically aligned one by one, and the tops of the straight rods 11 at both ends of the second square rod penetrate the corresponding first square rod and are vertically slidably connected;

[0099] A positioning assembly, the positioning assembly includes an upper positioning member installed at the bottom of the first sliding frame 201 and a lower positioning member installed at the top of the second sliding frame 301, and is used to drive the first sliding frame 201 and the second sliding frame 301 to move synchronously when the upper positioning member matches the lower positioning member;

[0100] The bottom of the straight rod 11 is fixed to the second square rod of the bottom bracket 3, and the top of the straight rod 11 is fixed to the first square rod of the top bracket 2, so that the first square rod and the second square rod can be relatively fixed under the action of the straight rod 11, so that when the first sliding frame 201 and the second sliding frame 301 drive the stabilizing line to move synchronously under the locking action of the locking assembly, the two moving points of the stabilizing line can be vertically aligned on the first square rod and the second square rod, which is beneficial to the alignment of the stabilizing line.

[0101] As an optional embodiment, it also includes:

[0102] A plurality of groups of intermediate sliding frames 8, four intermediate sliding frames 8 form a group, each group of intermediate sliding frames 8 is arranged in a vertical array, each group of intermediate sliding frames 8 is connected by a clamping assembly, and a lower clamping piece is installed on the top of the top intermediate sliding frame 8, and an upper clamping piece is installed on the bottom of the bottom intermediate sliding frame 8;

[0103] Multiple groups of intermediate brackets 9, each group of intermediate brackets 9 is arranged in a vertical array and is arranged corresponding to each group of intermediate sliding brackets 8. The intermediate brackets 9 in the same group are composed of four third-party rods, and the four third-party rods are slidably connected at the ends through a corresponding group of intermediate sliding brackets 8 to form a frame;

[0104] Both ends of all third-party rods are provided with limiting holes 901 which are plugged and adapted to the straight rod 11;

[0105] When the depth of the wellbore 1 increases, even if the two ends of the stabilizing line are fixed, the middle of the stabilizing line will still shake violently under the action of the airflow, making the stabilizing line unstable, thereby affecting the role of the stabilizing line as a reference;

[0106] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: when the bottom bracket 3 starts to move downward, all the intermediate sliding frames 8 are connected to the second sliding frame 301 at the bottom through the locking assembly, so that all the intermediate brackets 9 move downward synchronously with the bottom bracket 3. After a certain height below the bottom bracket 3, the locking assembly connected to the intermediate sliding frame 8 at the top at this time cancels the locking position, so that the locking effect between the top intermediate sliding frame 8 and the second intermediate sliding frame 8 is cancelled, so that the top intermediate sliding frame 8 is separated from the combination of the lowered bottom bracket 3 and the remaining intermediate sliding frames 8. At the same time, since the weight of the intermediate sliding frame 8 and the intermediate support 9 connected thereto is insufficient to overcome the friction between the stabilizing line and the self-landing assembly, the intermediate sliding frame 8 and the intermediate support 9 connected thereto remain in the middle of the wellbore 1. Since the shape of the intermediate support 9 matches the inner diameter of the wellbore 1, the four corners of the intermediate support 9 are against the inner wall of the wellbore 1, so that the intermediate support 9 will not produce a large range of shaking inside the wellbore 1, thereby positioning the stabilizing line in the middle position, which is beneficial to avoid the situation where the stabilizing line is fixed at only the two ends and is difficult to maintain stability when the depth of the wellbore 1 increases, thereby improving the efficiency of the stabilizing line arrangement.

[0107] As an optional embodiment, the upper clamping member includes:

[0108] Four first slide grooves 701 are respectively opened at the bottom of four first sliding frames 201 or the middle sliding frame 8;

[0109] Four groups of limit sliders 703, two limit sliders 703 form one group, the four groups of limit sliders 703 are symmetrically slidably installed inside the four limit sliders 703, and ordinary magnets 705 are fixed inside all the limit sliders 703;

[0110] The lower clamping parts include:

[0111] Four card slots 702 are respectively opened on the top of four second sliding frames 301 or the middle sliding frame 8;

[0112] The bottoms of the four groups of limit sliders 703 are respectively matched with the four card slots 702;

[0113] Four groups of first electromagnets 704, two first electromagnets 704 form one group, and the four groups of first electromagnets 704 are symmetrically fixed on both sides of the four slots 702;

[0114] Four second electromagnets 706 are respectively fixed at the centers of the four slots 702;

[0115] When the upper locking member matches the lower locking member, that is, when the bottom of the limiting slider 703 is inserted into the corresponding slot 702, since the limiting slider 703 is set in an L shape, after the bottom horizontal plate part of the limiting slider 703 is inserted into the bottom slot 702, under the action of the vertical force, the limiting slider 703 cannot be pulled out of the slot 702, thereby achieving the locking effect;

[0116] When the first electromagnet 704 and the second electromagnet 706 are powered on and started, the first electromagnet 704 generates a repulsive force with the same magnetic poles on the ordinary magnet 705, and the second electromagnet 706 generates an attractive force with different magnetic poles on the ordinary magnet 705, which can generate a driving force on the limit slider 703, so that the bottom cross plate part of the limit slider 703 is inserted into the interior of the slot 702, thereby realizing the locking effect. After the first electromagnet 704 and the second electromagnet 706 are powered on and started in the reverse direction, the first electromagnet 704 generates an attractive force with different magnetic poles on the ordinary magnet 705, and the second electromagnet 706 generates a repulsive force with the same magnetic poles on the ordinary magnet 705, which can generate a reverse driving effect on the limit slider 703, thereby pushing the bottom cross plate part of the limit slider 703 out of the interior of the slot 702, so that under the action of the vertical force, the limit slider 703 can be pushed out of the slot 702 to cancel the locking effect.

[0117] As an optional embodiment, the self-landing assembly includes:

[0118] A plurality of positioning frames 4, wherein a positioning frame 4 is fixed to the side walls of all the first sliding frames 201, the second sliding frames 301, and the middle sliding frame 8, and the positioning frames 4 fixed to the first sliding frames 201, the second sliding frames 301, and the middle sliding frame 8 that are vertically aligned are vertically aligned and form a group;

[0119] Multiple turning frames 401, one turning frame 401 is rotatably mounted on the side wall of all positioning frames 4, the turning frames 401 are connected to the corresponding positioning frames 4 through positioning pieces, and a straight groove 404 is vertically penetrated between the turning frames 401 and the corresponding positioning frames 4;

[0120] The stabilizing wire passes through the straight groove 404, and there is friction between the stabilizing wire and the straight groove 404, so that the falling of the bottom bracket 3 is hindered by the friction, thereby slowing down the falling speed of the bottom bracket 3, and preventing the bottom bracket 3 from falling quickly and causing the arrangement of the stabilizing wire to lose control;

[0121] The flip frame 401 can flip open after the positioning of the positioning piece is released, so that it is convenient to put the stabilizing line into the straight groove 404, which is conducive to the installation of the stabilizing line. After the stabilizing line passes through the straight groove 404 and is installed, the flip frame 401 and the positioning frame 4 are positioned by the positioning piece, which is conducive to avoiding the stabilizing line from escaping from the straight groove 404 and losing the positioning function.

[0122] As an optional embodiment, the self-landing assembly further includes:

[0123] Four fixing frames 5 are respectively fixed to the bottom of the four second sliding frames 301;

[0124] Four first pulleys 501 are rotatably mounted inside four fixing frames 5 respectively;

[0125] Four lifting frames 502 are respectively mounted on the side walls of the fixed frame 5 in a vertically slidable manner;

[0126] Four second pulleys 503 are rotatably mounted inside the four lifting frames 502 respectively;

[0127] Four cylinders 504 are respectively fixed on the side walls of four lifting frames 502, and the tops of the telescopic rods of the four cylinders 504 are fixed with fixing plates 506, and the four fixing plates 506 are respectively fixedly connected to the four fixing frames 5;

[0128] Four motors 505 are respectively fixed on the side walls of the four lifting frames 502, and are used to drive the corresponding second pulleys 503 to rotate;

[0129] After the motor 505 is started, it can drive the corresponding second pulley 503 to rotate through the output shaft. After the cylinder 504 is started, it can drive the fixed plate 506 to move through the telescopic rod. The fixed plate 506 is fixedly connected to the fixed frame 5, and the cylinder 504 is fixed on the side wall of the lifting frame 502. Therefore, by starting the cylinder 504, the distance between the fixed frame 5 and the lifting frame 502 is adjusted, thereby adjusting the distance between the first pulley 501 and the second pulley 503. When the distance between the first pulley 501 and the second pulley 503 is reduced, the squeezing of the stabilizing line can be increased, thereby achieving the fixation of the stabilizing line by increasing the squeezing force on the stabilizing line. After the stabilizing line is fixed by increasing the squeezing, the motor 505 drives the second pulley 503 to rotate, and the stabilizing line can be adjusted by the rotation of the second pulley 503 to release and reel in the stabilizing line, thereby adjusting the position of the bottom bracket 3 in the wellbore 1, and the lower speed of the wellbore 1 can be adjusted, thereby adjusting the lower speed of the stabilizing line.

[0130] As an optional embodiment, it also includes:

[0131] A plurality of second slide grooves 1002 are arranged one by one corresponding to the intermediate brackets 9, are opened inside the corresponding intermediate brackets 9, and both ends penetrate the intermediate brackets 9;

[0132] A plurality of electric push rods 10, two electric push rods 10 form a group, and the two electric push rods 10 in the same group are symmetrically fixed inside a second slide groove 1002, and the electric push rods 10 in the same group are arranged in back to back;

[0133] A plurality of locking rods 1001 are arranged one by one corresponding to the electric push rods 10 and fixed to the ends of the telescopic rods of the corresponding electric push rods 10;

[0134] After the electric push rod 10 is started, it can push the connected locking rod 1001 to move through the telescopic rod. When the middle sliding frame 8 and the middle bracket 9 are separated from the bottom bracket 3, the limiting holes 901 at both ends of the third rod of the middle bracket 9 are no longer blocked by the straight rod 11 passing through, so that the locking rod 1001 can be extended from the end of the second slide groove 1002 under the pushing action of the electric push rod 10, so that the locking rod 1001 extended at the end can extend the length of the third rod, so that the locking rod 1001 is more closely pressed against the inner wall of the wellbore 1, so that the middle bracket 9 has no room to shake inside the wellbore 1, thereby positioning the middle bracket 9, so that the middle bracket 9 positions the stabilizing line, so that the middle part of the stabilizing line is positioned and restricted, which is conducive to avoiding the occurrence of violent shaking in the middle part of the stabilizing line.

[0135] As an optional embodiment, the positioning member includes:

[0136] A plurality of limiting balls 402 are fixed on the side wall of the flip frame 401 in a vertical array;

[0137] A plurality of limiting grooves 403 are provided on the side wall of the positioning frame 4 and are plugged and matched with the limiting balls 402;

[0138] The limiting ball 402 is made of flexible rubber. When the limiting ball 402 is inserted into the limiting groove 403, the limiting groove 403 matches the limiting ball 402, so that the limiting ball 402 is blocked inside the limiting groove 403 and will not fall out until the limiting ball 402 is pulled by an external force, so that the limiting ball 402 deforms itself under the action of the rigid force, and thus falls out from the limiting groove 403, which is beneficial to the positioning between the positioning frame 4 and the flip frame 401.

[0139] As an optional embodiment, it also includes:

[0140] A plurality of ray lamps 601 are respectively fixed to the bottom of all the turning frames 401 except the top turning frame 401;

[0141] A plurality of receivers 602 are respectively fixed on the top of all the turning frames 401 except the bottom turning frame 401, and the receivers 602 are used to receive the radiation from the radiation lamp 601;

[0142] The ray lamp 601 emits rays downward. When the first sliding frame 201 is aligned with the second sliding frame 301 and the middle sliding frame 8, that is, when all positions of the stable line are aligned, the rays emitted downward by the ray lamp 601 are received by the receiver 602, which means that all positions of the stable line are aligned and the stable line is in a vertical state. Therefore, the state of the stable line can be detected, which is beneficial to avoid the stable line from shaking under the action of airflow and affecting the reference to the wellbore 1.

[0143] An auxiliary method for installing an integral line stabilization auxiliary device for vertical shaft equipment, a control unit is installed on the top bracket 2, the control unit includes a user end, and the positioning components are numbered 1, 2, 3... from top to bottom. The auxiliary method includes the following steps:

[0144] The control unit obtains the landing distance information h from the self-landing component;

[0145] The control unit obtains the landing distance information H from the user end;

[0146] The control unit substitutes the landing distance information h and the landing spacing information H into the judgment formula h=nH, where n is any positive integer. If the judgment formula is met, the control unit generates separation control information and stores the value of n that meets the judgment formula as N;

[0147] The control unit sends the separation control information to the blocking component numbered N to control the corresponding blocking component to cancel the blocking;

[0148] When the self-landing assembly falls, the falling distance can be recorded, that is, the number of rotations of the output shaft of the motor 505 is recorded, so as to calculate the edge rolling distance of the second pulley 503, thereby recording the falling distance and forming the falling distance information h. Then, the self-landing assembly sends the falling distance information h to the control unit, so that the control unit obtains the falling distance information h.

[0149] The staff can input the drop distance information H through the user terminal, and the drop distance information H is the distance between the adjacent intermediate sliding frames 8 that need to be arranged, so that the control unit can obtain the drop distance information H from the user terminal;

[0150] The control unit then substitutes the landing distance information h and the landing spacing information H into the judgment formula h=nH, and then successively substitutes n=1, n=2, n=3... to perform judgment. When the judgment formula is met, for example, when n=2, the control unit generates separation control information, and the control unit stores N=n=2. The control unit then sends the separation control information to the positioning component numbered 2, and the controller cancels the positioning, so that the middle sliding frame 8 above the positioning component numbered 2 is disengaged, thereby realizing the separation and release of the middle sliding frame 8 at each interval, so that the stable line is positioned at each interval, which is beneficial to slow down the shaking of the stable line.

[0151] Working principle of the present invention: After the device is installed at the opening of the wellbore 1, when the stabilizing line needs to be arranged, the staff passes the stabilizing line through the self-drop assembly, so that the four stabilizing lines that need to be arranged are arranged at the four corners of the position of the first sliding frame 201 after being installed through the self-drop assembly, thereby completing the preliminary positioning of the stabilizing line;

[0152] Then, according to the inner diameter of the wellbore 1, the staff can push the first sliding frame 201 to move on the first square rod of the top bracket 2. The movement of the first sliding frame 201 can drive the movement of the stabilizing line, thereby driving the stabilizing line to move on the first square rod for position adjustment;

[0153] The first square rod of the top bracket 2 is connected to the second square rod of the bottom bracket 3 by a synchronous adjustment component, and the first sliding frame 201 is connected to the second sliding frame 301 by a synchronous adjustment component, so that when the stabilizing line moves on the first square rod through the first sliding frame 201, the stabilizing line passing through the bottom bracket 3 is synchronously moved on the second square rod through the second sliding frame 301, so that the positions of the stabilizing line on the top bracket 2 and the bottom bracket 3 are synchronously moved and vertically aligned, so that when the stabilizing line is lowered, the stabilizing line can be vertically aligned by aligning the top bracket 2 and the bottom bracket 3, which is conducive to positioning the stabilizing line when the stabilizing line is arranged;

[0154] After the adjustment of the stabilizing line is completed, the staff starts the self-dropping assembly, which can control the bottom of the bottom bracket 3, so that the bottom bracket 3 drives the stabilizing line to move downward to move the stabilizing line downward. The frame structure of the bottom bracket 3 is basically in contact with the inner wall of the wellbore 1, so that the bottom bracket 3 will not produce violent shaking inside the wellbore 1 during the downward process, which is conducive to reducing the occurrence of strong shaking of the stabilizing line due to the airflow inside the wellbore 1 during the downward process, thereby helping to reduce the shaking of the stabilizing line and improving the efficiency of the stabilizing line arrangement;

[0155] After the lowering is completed, the bottom bracket 3 is fixed on the line stabilizing frame at the bottom of the wellbore 1, so as to achieve the fixation of the line stabilizing frame.

[0156] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
