Description

Technical Field

[0001] The invention relates to the technical field of shaft exploration, and in particular to a measuring device which is easy to carry, quick to assemble and disassemble, and can measure. Background Art

[0002] At present, most well surveys are conducted by traction, which mainly consists of a traction lifting device, a measuring platform, measuring equipment, and a guide limit device. The traction lifting device drags the measuring platform and the measuring equipment on the platform to move up and down in the Z direction in the well for surveying. The guide limit device generally uses a rope fixed from top to bottom to guide the measuring platform + measuring equipment to move vertically upward and limit the rotation and swing of the measuring platform + measuring equipment. Most measuring equipment uses a horizontal laser rangefinder or a stereo camera group or a combination of the two, a height measurement sensor (height position determination), an angle sensor, a horizontal positioning sensor (horizontal position determination), etc.

[0003] For the traditional traction measurement device, the guide limit device is generally to place 1-2 ropes from the top of the shaft to the bottom pit, and then fix it, and the laying out and installation takes a long time. In addition, the height position determination and horizontal position determination generally require additional reference elements, especially the horizontal position determination, the installation of reference elements or the installation and debugging of sensors takes a long time. The current mainstream methods for determining the horizontal position are: one method is to use 1-2 plumb lines from the top to the bottom of the shaft as the reference element, and measure the distance in the X and Y directions of the plumb line cross section through the sensor mounted on the platform to determine; the other is to shoot two laser beams placed in the bottom pit of the shaft to the target on the mobile platform, and identify the horizontal position of the target spot through the sensor on the platform. The first method is that the laying out and installation takes a long time, and the second method is that the installation and debugging of the laser beam takes a long time to be vertical and aligned, and it is necessary to ensure that the laser beam can hit the effective measurement range of the target from the bottom to the top of the shaft during the measurement operation, otherwise the survey needs to be stopped. In addition to the traction line, the entire survey also requires laying 1-2 guide lines or plumb lines for horizontal positioning. In order to prevent the risk of entanglement of several lines, they are generally required to be laid one by one. Even if they are laid one by one, there is still a risk of entanglement. The entire installation process takes a very long time and the operation process of personnel in the well is time-consuming and unsafe. Summary of the invention

[0043] A measuring device that is easy to carry, quick to assemble and disassemble, and measure, comprising:

[0044] A traction and lifting device 20, which is fixed at the top door opening 11 and is used to drag the measuring assembly to move up and down along the Z direction in the hoistway 10;

[0045] A measuring platform 30, used for carrying a measuring device;

[0046] A measuring device 40, arranged on the measuring platform 30, for conducting well survey;

[0047] Wherein, the traction lifting device 20 comprises:

[0048] A traction line 21, used for transmitting traction force;

[0049] A guide wheel device 22, used to guide the moving direction of the traction wire 21;

[0050] The traction boom 24 has a retractable and foldable structure to adapt to the sizes of different hoistways 10 and facilitate carrying and quick disassembly and assembly;

[0051] Personnel safety protection arm 25, used to provide safety protection during the traction and lifting process;

[0052] A winch device 26, used for retracting and releasing the traction line 21 and controlling the operation of the traction lifting device 20;

[0053] The traction mounting frame 27 is used to fix the traction lifting device 20 as a whole at the top floor door opening 11;

[0054] The traction lifting device 20 drags the measuring assembly consisting of the measuring platform 30 and the measuring equipment 40 through the traction line 21 to move up and down in the hoistway 10 in the Z direction to survey the hoistway.

[0055] Specifically, as shown in the figure, the traction mounting frame 27 includes a plurality of support columns 275 and a bottom plate 274 horizontally supported by the support columns 275, the winch device 26 is fixedly mounted on the bottom plate 274, a first column 271 is vertically arranged on the side of the bottom plate 274 close to the top floor door opening 11, a second column 273 is vertically arranged on the side of the bottom plate 274 away from the top floor door opening 11, and a support plate 272 is horizontally arranged on the side of the first column 271;

[0056] When in working state, the first column 271 is a supporting column for the traction cantilever 24 and the personnel safety protection arm 25, and the supporting plate 272 horizontally supports the traction cantilever 24; when in transport state, the second column 273 is a connecting and fixing installation column for the traction cantilever 24 and the personnel safety protection arm 25.

[0057] Specifically, as shown in the figure, a mounting plate 276 is provided at the lower end of the support column 275, and the traction mounting frame 27 is anchored to the top floor through the mounting plate 276. The lower end of the support column 275 is provided with a caster 277 for easy transportation.

[0058] In order to save on-site installation time, the entire traction lifting device has been assembled before leaving the factory. The whole device is folded up for easy transportation. The traction mounting frame 27 is anchored to the top floor through the mounting plate 276. When working, the device is unfolded as a whole. The caster 277 plays the role of moving the traction mounting frame 27 during transportation. The bottom of the caster is flush with the lower end surface of the mounting plate or slightly higher than the lower end of the mounting plate. During transportation, the entire traction lifting device is slightly tilted toward the caster side for easy transportation. The use of two larger casters is convenient for transportation operations on construction site sections with uneven road surfaces.

[0059] The traction mounting frame 27 is carried to the vicinity of the top floor door opening 11, and the traction mounting frame 27 is firmly anchored to the top floor floor using anchors (such as bolts, nuts, etc.) through the mounting plate 276. Ensure that all components of the traction mounting frame 27 are installed in place and the connection is firm and reliable.

[0060] In the working state, the first column 271 serves as the main support column for the traction boom 24 and the personnel safety protection arm 25. The traction boom 24 is connected to the first column 271 and can extend horizontally on the support plate 272 to support the traction line 21 and the measuring assembly. The personnel safety protection arm 25 is also connected to the first column 271 to provide necessary safety protection for the operator. The winch device 26 is fixedly mounted on the bottom plate 274. By controlling the operation of the winch device 26, the traction line 21 can be retracted and released, thereby controlling the up and down movement of the measuring assembly in the shaft 10.

[0061] After the shaft survey is completed, the traction mounting frame 27 needs to be disassembled or folded for transportation or storage. At this time, the second column 273 serves as a connecting and fixing mounting column for the traction boom 24 and the personnel safety protection arm 25, and the traction boom 24 and the personnel safety protection arm 25 can be connected to the second column 273 to form a compact transportation unit. The traction mounting frame 27 is equipped with casters 277, and the traction mounting frame 27 can be moved to a transportation vehicle or storage area by the casters 277. During transportation, it is necessary to ensure that the various components of the traction mounting frame 27 are firmly fixed to prevent damage or loss during transportation.

[0062] Specifically, as shown in the figure, the traction cantilever 24 includes a first square beam 241 and a second square beam 243 which are telescopically sleeved inside and outside. A slider 242 is slidably installed in the inner cavity of the first square beam 241. A pair of U-shaped sliders 242 are fixedly installed in the inner cavity of the ends of the first square beam 241 and the second square beam 243. The pair of U-shaped sliders 242 constitute the sliding inner cavity of the second square beam 243. The end of the second square beam 243 movably extends into the sliding inner cavity. Long slots are opened on the front and rear sides of the first square beam 241. A positioning guide rod 244 passes through the long slot and is connected to the second square beam 243. The positioning guide rod 244 can pull the second square beam 243 to slide left and right in the direction of the long slot. It also includes a fixed handle 245 that cooperates with the positioning guide rod 244, and the telescopic length of the second square beam 243 is fixed by the fixed handle 245.

[0063] The inner end of the first square beam 241 is rotatably matched with the first column 271 through a rotating shaft 248, a bearing 246 is arranged between the rotating shaft 248 and the first square beam 241, a butterfly spring group 247 is sleeved on the rotating shaft 248, the upper end of the butterfly spring group 247 abuts against the rotating shaft 248, and the lower end abuts against the top surface of the first square beam 241, and also includes a limit plate 249 and a butterfly bolt 2491 used in conjunction. When in working state, the limit plate 249 and the butterfly spring group 247 are Bolts 2491 fix the first square beam 241 on the first column 271; in the transportation state, the second square beam 243 is shortened to the minimum length and locked by the positioning guide rod 244 and the fixing handle 245 for easy transportation. After removing the limit plate and butterfly bolts on the first square beam, the traction cantilever is rotated 180° around the rotating shaft and fixed to the second column by the limit plate and butterfly bolts. The traction cantilever serves as a handrail for transportation.

[0064] The inner end of the first square beam 241 rotates with the first column 271 through the rotating shaft 248 to realize the rotation of the traction cantilever 24 within a certain range. A bearing 246 is arranged between the rotating shaft 248 and the first square beam 241 to reduce the friction resistance during rotation and improve the flexibility and stability of rotation. The butterfly spring group 247 is sleeved on the rotating shaft 248, with its upper end abutting against the rotating shaft 248 and its lower end abutting against the top surface of the first square beam 241. The butterfly spring group 247 provides a certain preload force, which helps to maintain the stability of the traction cantilever 24 after rotation. In the working state, the limit plate 249 is installed on the first column 271 and clamped with the first square beam 241 by the butterfly bolt 2491, thereby limiting the further rotation of the traction cantilever 24. The traction cantilever 24 is adapted to the survey requirements of different wells by adjusting the telescopic length. At this time, the traction cantilever 24 can stably support the traction line 21 and the measurement assembly to ensure the smooth progress of the survey work.

[0065] In the transport state, in order to reduce the volume and facilitate carrying, the traction cantilever 24 needs to be folded and shortened. At this time, the second square crossbeam 243 is shortened to the minimum length and locked by the positioning guide rod 244 and the fixing handle 245. At the same time, the limit plate 249 and the butterfly bolt 2491 can be loosened to allow the traction cantilever 24 to rotate 180° relative to the first column 271, so that the position of the traction cantilever 24 corresponds to the position of the second column up and down, and it is fixed to the second column by the limit plate and butterfly bolt moved from the first column so that it can be folded up, and the traction cantilever acts as a handrail for transportation.

[0066] Specifically, as shown in the figure, the personnel safety protection arm 25 has the same telescopic mechanism as the traction cantilever 24, the inner end of the personnel safety protection arm 25 is rotatably connected to the hinge bracket 251 through the hinge shaft 252, the hinge bracket 251 is fixedly installed on the first column 271, the hinge bracket 251 is a U-shaped structure with an opening, and its opening direction is toward the second column 273, and the hinge shaft 252 is provided with a first butterfly nut 253 for fixing the personnel safety protection arm 25;

[0067] There are two personnel safety protection arms 25, and the two personnel safety protection arms 25 are symmetrically arranged about the traction cantilever 24. A fixed bracket 278 is arranged on the second column 273. When in working state, the protection arms on the left and right sides are rotated around the hinge shaft 252 and unfolded to be attached to the end surface of the hinge bracket 251, and then the first butterfly nut 253 is locked to prevent the protection arm from rotating. The unfolded protection arm is attached to the wall at both ends of the top floor doorway 11; when in transportation state, the length of the personnel safety protection arm 25 is shortened to the minimum length, the first butterfly nut 253 is loosened, and the protection arms on the left and right sides are rotated inward 90° respectively, and are fixedly connected to the fixed bracket 278 to form a folded shape.

[0068] In the working state, the personnel safety protection arm 25 needs to be unfolded and provide safety protection. First, by adjusting the telescopic mechanism, the personnel safety protection arm 25 is adjusted to a suitable length. Then, the inner end of the personnel safety protection arm 25 is rotatably connected to the hinge bracket 251 through the hinge shaft 252. Since the hinge bracket 251 is a U-shaped structure fixedly mounted on the first column 271, and its opening direction is toward the second column 273, the personnel safety protection arm 25 can rotate around the hinge shaft 252. The personnel safety protection arms 25 on the left and right sides are rotated and unfolded around the hinge shaft 252 respectively, so that they are attached to the end surface of the hinge bracket 251. At this time, the personnel safety protection arm 25 will be unfolded and covered on the two end walls of the top floor doorway 11, providing safety protection for the operator. Finally, by tightening the first butterfly nut 253, the personnel safety protection arm 25 is fixed to the hinge bracket 251 to prevent it from rotating or shaking during work.

[0069] In order to reduce the volume and facilitate carrying in the transport state, the personnel safety protection arm 25 needs to be folded and retracted. First, by adjusting the telescopic mechanism, the length of the personnel safety protection arm 25 is shortened to the minimum length. Then, the first butterfly nut 253 is loosened to allow the personnel safety protection arm 25 to rotate around the hinge shaft 252. At this time, the left and right personnel safety protection arms 25 can be rotated inward by 90° each, so that they form a folded state with the fixing bracket 278.

[0070] The fixing bracket 278 is arranged on the second column 273, and is used to fix the folded personnel safety protection arm 25 in the transportation state. The folded personnel safety protection arm 25 is connected to the fixing bracket 278 by bolts to ensure that it will not shake or fall off during transportation.

[0071] The design of the personnel safety protection arm 25 fully considers safety and convenience. In the working state, it can be stably unfolded and provide safety protection; in the transportation state, it can be conveniently folded and retracted to reduce the volume and be easy to carry. The protection arm 25 can adapt to the survey needs of different wells and provide all-round safety protection for operators.

[0072] Specifically, as shown in the figure, the winch device 26 includes a winding device 261, a ratchet rocker arm 262, a mechanical wire arrangement device 263, and a roller column group 264. The winding device winds the traction line onto the drum; the mechanical wire arrangement device adopts a universal reciprocating screw wire arrangement structure so that the wire rope can be neatly arranged in multiple layers on the drum of the winding device during the winding process; the roller column group adopts a pair of rolling and rotatable roller columns; the ratchet rocker arm can be rotated forward and reversed to reel in and out the traction line on the drum.

[0073] The winding device is the core part of the winch device. It contains a drum for neatly winding up the traction line. When the winch device is working, the traction line will be wound on the drum, so as to realize the winding and releasing of the traction line. The ratchet rocker arm is the component that drives the winding device to rotate. By rotating the ratchet rocker arm forward or reverse, the drum of the winding device can be driven to rotate clockwise or counterclockwise, so as to realize the winding and releasing operation of the traction line. The design of the ratchet rocker arm also ensures that the winch device can remain stable and prevent reversal when driven in one direction. The mechanical wire arrangement device adopts a universal reciprocating screw rod wire arrangement structure. Its main function is to guide the traction line to be neatly arranged on the drum in multiple layers during the winding process. Through the reciprocating motion of the reciprocating screw rod, the mechanical wire arrangement device can ensure that the traction line will not cross or overlap during the winding process, so as to keep the traction line on the drum neat and orderly. The roller column group consists of a pair of roller columns that can roll and rotate, which are located next to the drum of the winding device. The roller column group is installed on the guide slider of the mechanical wire arrangement device, and moves with the guide slider in the wire arrangement device of the wire rope; the roller column always has the elastic force to clamp the wire rope (whether in working or non-working conditions), so there is no tangled wire in any traction-free situation. The roller column group is installed on the guide slider mainly to keep the direction of its elastic clamping force close to the right angle with the wire rope axis at the drum end, rather than changing with the movement of the traction rope, so as to avoid the phenomenon of stagnation caused by excessive angle between the clamping force and the traction rope.

[0074] The winch device 26 has three gears: forward, reverse and neutral. There is no brake in neutral, and brakes are provided in forward and reverse. The winch device 26 can run forward and reverse in neutral, and can be locked by the forward and reverse gears after reaching the destination.

[0075] Different from the traditional traction manual winch, the transmission manual winch is a deceleration winch so that it can easily lift heavier weights. Because the measuring platform 30 and the measuring device 40 are relatively light, generally less than 3kg, and in order to achieve a faster lifting speed, the gear on the ratchet rocker arm 262 is a large gear, and the gear on the drum that meshes with it is a small gear, which is a speed-increasing winch, and then the torque of the hand-cranked rocker arm is controlled by appropriately lengthening the rocker arm rotation radius.

[0076] For example, if you are surveying a 100m shaft, and if you control the average linear speed of the winch to be about 0.3m / s-0.4m / s, you can complete the survey of the 100m shaft in about ten minutes.

[0077] Specifically, as shown in the figure, the guide wheel device 22 includes a guide wheel arranged on one end of the first square beam 241 and the second square beam 243 away from each other, and the traction line 21 is wound around the two guide wheels and connected to the measuring component.

[0078] Specifically, as shown in the figure, an anti-slip device 23 is provided at the position of the guide wheel on the outside, and the anti-slip device 23 includes a mounting plate 231, a roller 232, a roller shaft 233, and a second butterfly nut 234. The mounting plate 231 is vertically arranged on both sides of the guide wheel, and a U-shaped groove is opened on the top of the mounting plate 231. The roller shaft 233 cooperates with the U-shaped groove, and the roller shaft 233 is fixed to the mounting plate 231 by the second butterfly nut 234. The roller 232 is arranged on the roller shaft 233, and the position of the roller 232 corresponds to the position of the guide wheel up and down to prevent the traction rope from slipping out.

[0079] The guide wheel device 22 mainly includes guide wheels arranged on the ends away from the first square beam 241 and the second square beam 243. The main function of these guide wheels is to guide the direction of the traction line 21 to ensure that the traction line 21 can be connected to the measuring assembly smoothly and accurately.

[0080] During operation, the traction line 21 will bypass the two guide wheels to form a certain tension and path. The design and position of the guide wheels ensure that the traction line 21 will not deviate from the predetermined track during transmission, thereby ensuring that the measurement component can accurately receive the signal or force transmitted by the traction line 21. The mounting plate 231 is vertically arranged on both sides of the guide wheel, providing a foundation for the installation of the roller 232. The U-shaped groove design on the top of the mounting plate 231 enables the roller shaft 233 to cooperate with it and be fixed to the mounting plate 231 through the second butterfly nut 234. The roller 232 is arranged on the roller shaft 233, and its position corresponds to the position of the guide wheel up and down. The main function of the roller 232 is to form an additional support point to prevent the traction line 21 from coming off the guide wheel during transmission. When the traction line 21 bypasses the guide wheel, it contacts the roller 232 and keeps its position stable by the rolling of the roller 232. The roller shaft 233 cooperates with the mounting plate 231 through the U-shaped groove and is fixed by the second butterfly nut 234. This design enables the roller 232 to be securely mounted on the mounting plate 231 and is convenient for adjustment and replacement.

[0081] The guide wheel device 22 and the anti-slip device 23 work together to ensure the stability and accuracy of the traction wire 21 during the transmission process. The guide wheel device 22 guides the direction of the traction wire 21 to ensure that it can be connected to the measuring component smoothly and accurately. The anti-slip device 23 effectively prevents the traction wire 21 from slipping off the guide wheel during the transmission process by providing an additional support point. This design not only improves the stability and reliability of the entire system, but also reduces maintenance costs and failure rates.

[0082] Specifically, as shown in the figure, the connecting end of the traction rope is equipped with a high-speed rotating bearing 211 and a rotatable hook 212, and the rotatable hook 212 is suspended and matched with the upper end of the measuring platform 30.

[0083] The measuring platform 30 is mainly composed of a platform, a protective rod, a lifting lug, a lifting wire rope, etc. The platform is an installation and mounting platform for the measuring equipment 40. The protective rod protects the measuring equipment 40 from being damaged after hitting the shaft wall, and protects the safety of the measuring equipment 40. The traction and lifting points of the lifting lug measuring platform use 3 or more lifting lugs to reduce the risk of shaking and tilting of the measuring equipment. The lifting wire rope is set at an angle ≥45°, and the connection point with the rotating hook 212 is set on the center of gravity of the measuring platform 30 and the measuring equipment 40, so that the force is more balanced and the risk of rollover is reduced; the laser radar 41 rotates clockwise or counterclockwise around the Z direction. In order to reduce the rotation of the measuring platform 30, a turntable with a rotation direction opposite to that of the laser radar 41 can be added to the measuring platform to resist the rotation, flipping and vibration caused by the self-rotation of the measuring equipment.

[0084] Specifically, as shown in the figure, the measuring device 40 includes a multi-line laser radar 41, an IMU 42, a panoramic camera 43, a processor and a storage 44.

[0085] The measuring device 40 utilizes the increasingly mature multi-sensor fusion SLAM technology in the current market, and combines the high-precision laser radar 41 with a large laser field of view and a long range, the panoramic camera 43, and the IMU 42 for use, and obtains continuous and accurate position parameters through multiple sensor data fusion technology to realize the SLAM system. With an efficient processor and storage 44, combined with AI intelligent algorithms, it can generate high-quality laser point cloud data models in real time to achieve the measurement and output of the shaft; and after post-processing, the point cloud data is converted into a three-dimensional surface model, and the image taken by the camera is mapped to the reconstructed model to generate a color three-dimensional reconstruction model of the shaft, which can be used for measurement and analysis of the shaft, such as foreign body recognition.

[0086] The multi-line laser radar 41 with a large laser field of view, long range, high frequency and high precision is used not only to detect the precise distance between the laser radar and each scanning point on the four walls for later modeling; it also has an important role. Since there are few reference elements for the measurement and positioning of the shaft body, the laser radar 41 with a large laser field of view and long range can more effectively capture the feature points of the shaft point cloud, especially the feature points of the top upper plane ceiling or the bottom lower plane ground of the shaft. In this way, the radar 41 with a wide viewing angle and long range is deeply combined with the IMU to provide the continuity and accuracy of the shaft data positioning and ensure the positioning accuracy. It is particularly beneficial for the measurement of high-rise or super-high-rise shafts.

[0087] The mobile phone APP can connect to the device via Bluetooth hotspot to achieve remote control of the device, such as starting and shutting down the device, and viewing the point cloud data and scanning trajectory collected by the device in real time.

[0088] The specific measurement process is as follows:

[0089] Installation of the traction lifting device 20 and release of the traction line 21: outside the top door area, the traction lifting device 20 is installed and fixed, and the traction line is released from the top to the bottom, and the release is stopped when the bottom pit is approximately higher than the height of the measuring platform. This process completes the release of the traction line.

[0090] Initialization of the measuring device 40: In the pit, the measuring platform 20 and the measuring device 40 are placed under the traction line, the switch of the measuring device 40 is turned on, and the device begins to initialize. After the measuring device 40 completes the initial positioning, the measuring platform 20 and the measuring device 40 are connected to the traction line hook 212.

[0091] Measurement: Outside the top-floor door area, the lifting device 20 is lifted and pulled until the measuring platform 20 reaches the top-floor door opening position, the measuring device 40 completes the measurement of the shaft, and the measuring device 40 is controlled by the APP to stop the measurement.

[0092] Recovery of measuring device: Outside the top-level door area, use the mobile phone APP to confirm whether the preliminary scanning results are normal. If normal, the measurement can be ended and the measuring equipment can be recovered.

[0093] Data processing: Data is transmitted to PC for data processing and modeling, and a true color point cloud model of the shaft is output, from which the key data required for measurement is obtained; the point cloud data can be converted into a three-dimensional surface model, and the image taken by the camera is mapped onto the reconstructed model to generate a color three-dimensional reconstruction model of the shaft, which can be used for measurement and analysis of the shaft, such as identification of foreign objects such as steel bars protruding from the shaft surface.

[0094] The entire installation and measurement process of this measuring device can be easily completed in half an hour, which is highly efficient compared to the previous measuring devices that took half a day or even a day to complete the installation and measurement. The traction lifting device 20 of this measuring device is a relatively large and heavy component of the entire measuring device. Through a series of hinge structures, it can be stretched into a large component during work and folded into a relatively small component during transportation. In addition, two casters are added for transportation, which makes it highly portable.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
