Description

Technical Field

[0001] This invention relates to the field of well exploration technology, and in particular to a well exploration device. Background Technology

[0002] A wellbore surveying device is a tool used to survey the internal conditions of a wellbore. It is mainly used to measure and record various parameters inside the wellbore, such as well diameter, effective cross-section, and eccentricity. Through these measurement data, the internal conditions of the wellbore can be surveyed intuitively, thereby accurately assessing the shape and size of the wellbore to ensure its safety and stability.

[0003] Currently, hoistway surveying devices consist of one traction rope and two guide ropes. The traction rope provides power for the movement of the device, while the guide ropes guide its movement. When installing the device, these three steel wire ropes need to be laid from the top of the hoistway (which can be hundreds of meters high) to the bottom pit. To allow simultaneous laying of all three ropes, a weight is attached to the end of each rope before the traction rope is lowered to allow the weight to fall. Existing technology uses a motor to drive the traction rope and a manual winch with damping components to control the movement of the guide ropes, thus controlling the laying speed. However, this method cannot effectively control the winding speed of both the traction rope and the guide ropes, thereby affecting the efficiency of elevator hoistway surveying. Summary of the Invention

[0004] The purpose of this invention is to provide a shaft surveying device to solve the problem that existing shaft surveying devices cannot effectively control the take-up speed, thus affecting the surveying efficiency of elevator shafts.

[0013] As an optional solution for the aforementioned wellbore exploration equipment, the wellbore exploration equipment further includes a cable routing device, which comprises several units, each of which is located one-to-one between the first winding reel and the first guide reel, and between the second winding reel and the second guide reel.

[0014] As an optional solution for the aforementioned wellbore exploration equipment, the cable laying device includes a cable laying bracket, a guide rod, a reciprocating screw, and a cable laying assembly. The cable laying bracket is mounted on the support frame; the guide rod is mounted on the cable laying bracket, and the reciprocating screw is rotatably mounted on the cable laying bracket; one end of the cable laying assembly is slidably sleeved on the guide rod, and the other end of the cable laying assembly is engaged with the reciprocating screw; the reciprocating screw between the first winding wheel and the first guide wheel is driven by the first winding wheel, so that the reciprocating screw drives the cable laying assembly to reciprocate along the axial direction of the first winding wheel, and the traction rope can pass through the cable laying assembly; the reciprocating screw between the second winding wheel and the second guide wheel is driven by the second winding wheel, so that the reciprocating screw drives the cable laying assembly to reciprocate along the axial direction of the second winding wheel, and the guide rope can pass through the cable laying assembly.

[0015] As an alternative to the aforementioned wellbore exploration equipment, the cable assembly includes a mounting block and two rollers rotatably mounted on the mounting block, the two rollers being able to elastically clamp the traction rope or the guide rope.

[0016] As an alternative to the aforementioned wellbore exploration equipment, the first guide wheel and the second guide wheel are I-shaped rollers or V-groove rollers.

[0017] As an optional solution for the aforementioned wellbore surveying equipment, the wellbore surveying equipment further includes a rotation speed measuring device, which is mounted on the support frame and is used to measure the rotation speed of the first guide wheel.

[0020] As an optional solution for the aforementioned wellbore exploration equipment, the wellbore exploration equipment further includes a position adjustment device, which includes an adjustment bracket, a first reversing wheel, and a second reversing wheel. The adjustment bracket is mounted on the support frame and located between the guide device and the counterweight.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1-5 As shown in the figure, this embodiment provides a wellbore surveying device for surveying the internal conditions of a wellbore.

[0035] The well exploration equipment includes a support frame 1, a drive unit 2, a guide device 3, a synchronization component 4, and a counterweight 5. The drive unit 2 includes a motor 21, a first winding reel 22, and a traction rope 23. The motor 21 is mounted on the support frame 1, the first winding reel 22 is rotatably mounted on the support frame 1, one end of the traction rope 23 is wound around the first winding reel 22, and the other end of the traction rope 23 is provided with a first connecting member 24. The output end of the motor 21 is connected to the first winding reel 22 to drive the first winding reel 22 to rotate. By controlling the motor 21 to drive the first winding reel 22 to rotate, the traction rope 23 can be released or retrieved under the premise of power, thereby adjusting the height of the first connecting member 24.

[0036] The guiding device 3 includes a second winding wheel 31 and a guide rope 32. The second winding wheel 31 is rotatably mounted on the support frame 1. One end of the guide rope 32 is wound around the second winding wheel 31, and the other end of the guide rope 32 is provided with a second connecting member 33. Meanwhile, the synchronization component 4 includes a first synchronization wheel 41, a second synchronization wheel 42, and a synchronization chain 43. The first synchronization wheel 41 is coaxially connected to the first winding wheel 22, and the second synchronization wheel 42 is coaxially connected to the second winding wheel 31. The synchronization chain 43 is drive-connected to the first synchronization wheel 41 and the second synchronization wheel 42. Thus, through the transmission of the synchronization component 4, the second winding wheel 31 can rotate synchronously with the first winding wheel 22, enabling the unwinding or rewinding of the guide rope 32 under powered conditions, thereby adjusting the height of the second connecting member 33. Optionally, the chain joint of the synchronization chain 43 can be quickly disassembled and assembled for rapid on-site replacement.

[0037] The counterweight 5 is rotatably connected to the first connector 24 and the second connector 33. This allows the shaft surveying equipment to control the lifting and lowering of the counterweight 5 via the traction rope 23 and the guide rope 32, enabling the traction rope 23 and the guide rope 32 to move synchronously. This effectively controls the winding and unwinding speed of the traction rope 23 and the guide rope 32, thereby improving the efficiency of elevator shaft surveying. Optionally, both the first connector 24 and the second connector 33 are universal hooks, connecting to the counterweight 5 and allowing for horizontal rotation. This facilitates rapid deflation of the traction rope 23 and the guide rope 32 during lifting and lowering, preventing multiple ropes from becoming entangled.

[0038] Optionally, several guide devices 3 are provided, which enable several guide ropes 32 to be connected to the counterweight 5, thereby improving the load-bearing capacity of the counterweight 5 and also improving the stability of the counterweight 5 during movement. Further optionally, the guide device 3 also includes an adjusting handwheel 36, which is tractively connected to the second winding wheel 31 and used to tension or loosen the guide ropes 32 on the second winding wheel 31, allowing workers to manually adjust the tension of the guide ropes 32 on the second winding wheel 31.

[0039] like Figure 3 and Figure 4 As shown, the guiding device 3 also includes a first guide wheel 34 and a second guide wheel 35. Both the first guide wheel 34 and the second guide wheel 35 are rotatably mounted on the support frame 1. The first guide wheel 34 can support the traction rope 23 and guide the traction rope 23. The second guide wheel 35 can support the guide rope 32 and guide the guide rope 32. The first winding wheel 22, the second winding wheel 31, the first guide wheel 34 and the second guide wheel 35 are all on the same horizontal plane. Thus, by setting the first guide wheel 34 and the second guide wheel 35, the extension direction of the traction rope 23 and the guide rope 32 can be adjusted, which facilitates the installation of well exploration equipment. That is, the first guide wheel 34 can guide the traction rope 23, which extends horizontally, to extend vertically, and the second guide wheel 35 can guide the guide rope 32, which extends horizontally, to extend vertically, so that the traction rope 23 and the guide rope 32 can pull the counterweight to rise and fall. Optionally, the first guide wheel 34 and the second guide wheel 35 are I-shaped rollers or V-groove rollers, which limit the traction rope 23 and the guide rope 32, increase the wrap angle, avoid unnecessary friction and twisting, and improve the stability during the winding and unwinding process.

[0040] like Figures 3-5 As shown, the well exploration equipment also includes a cable routing device 6. The cable routing device 6 comprises several units, each corresponding to a specific location between the first winding reel 22 and the first guide reel 34, and between the second winding reel 31 and the second guide reel 35. The cable routing device 6 is used to route the traction rope 23 wound on the first winding reel 22 and the guide rope 32 wound on the second winding reel 31, thereby preventing the traction rope 23 from partially stacking on the first winding reel 22 and the guide rope 32 from being side-slipped and tangled on the second winding reel 31, and thus preventing the traction rope 23 and the guide rope 32 from being unable to be wound or unwound.

[0041] Specifically, the cable laying device 6 includes a cable laying bracket 61, a guide rod 62, a reciprocating screw 63, and a cable laying assembly 64. The cable laying bracket 61 is mounted on the support frame 1, the guide rod 62 is mounted on the cable laying bracket 61, the reciprocating screw 63 is rotatably mounted on the cable laying bracket 61, one end of the cable laying assembly 64 is slidably sleeved outside the guide rod 62, and the other end of the cable laying assembly 64 is meshed and sleeved outside the reciprocating screw 63, so that the cable laying assembly 64 can move along the guide rod 62 and the reciprocating screw 63. The reciprocating screw 63 between the first winding wheel 22 and the first guide wheel 34 is connected to the first winding wheel 22, so that the reciprocating screw 63 drives the cable laying assembly 64 to reciprocate along the axial direction of the first winding wheel 22, and the traction rope 23 can pass through the cable laying assembly 64. Thus, during the rotation of the first winding wheel 22 driven by the motor 21, the first… A winding wheel 22 drives a reciprocating screw 63 to rotate, causing the cable laying assembly 64 to drive the traction rope 23 to reciprocate along the axial direction of the first winding wheel 22. This prevents the traction rope 23 from partially stacking on the first winding wheel 22. At the same time, the reciprocating screw 63 between the second winding wheel 31 and the second guide wheel 35 is connected to the second winding wheel 31 so that the reciprocating screw 63 drives the cable laying assembly 64 to reciprocate along the axial direction of the second winding wheel 31. The guide rope 32 can pass through the cable laying assembly 64. Thus, when the motor 21 drives the synchronization assembly 4 to rotate the second winding wheel 31, the second winding wheel 31 can drive the reciprocating screw 63 to rotate, causing the cable laying assembly 64 to drive the guide rope 32 to reciprocate along the axial direction of the second winding wheel 31. This prevents the guide rope 32 from partially stacking on the second winding wheel 31.

[0042] The cable assembly 64 includes a mounting block 641 and two rollers 642 rotatably mounted on the mounting block 641. The two rollers 642 can elastically clamp the traction rope 23 or the guide rope 32, so that when no counterweight is set, the first connector 24 and the second connector 33 are in a suspended state. At this time, the two rollers 642 corresponding to the traction rope 23 can clamp the traction rope 23, and the two rollers 642 corresponding to the guide rope 32 can clamp the guide rope 32. This prevents the traction rope 23 on the first winding wheel 22 and the guide rope 32 on the second winding wheel 31 from being in a slack state, which would cause the cable to become tangled. During operation, if the counterweight gets stuck, or the traction rope 23 and / or the guide rope 32 breaks, the traction rope 23 and / or the guide rope 32 will be in a state of weightlessness. The two rollers 642 elastically clamp the traction rope 23 or the guide rope 32, which can prevent the cable from becoming tangled when winding and unwinding. Optionally, the roller column 642 is an elastic element, or the inside of the roller column 642 is a rigid element, and the rigid element is wrapped with an elastic element.

[0043] Furthermore, the wellbore exploration equipment also includes a speed measuring device 7, which is mounted on the support frame 1 and is used to measure the speed of the first guide wheel 34. By comparing the speed of the first guide wheel 34 with the speed of the motor 21, it can be determined whether the traction rope 23 is abnormally loose. Optionally, the speed measuring device 7 is an encoder. Simultaneously, the wellbore exploration equipment also includes a height measuring device, which is mounted on the counterweight 5 and is used to measure the height of the counterweight 5. Therefore, when the motor 21 is running, if the distance from the counterweight 5 to the bottom of the wellbore, as measured by the height measuring device, remains unchanged or changes abnormally, it can be determined that the traction rope 23 is abnormally loose. Optionally, the height measuring device is a height sensor.

[0044] like Figure 1 and Figure 2 As shown, the wellbore exploration equipment also includes a position adjustment device 8. The position adjustment device 8 includes an adjustment bracket 81, a first reversing wheel 82, and a second reversing wheel 83. The adjustment bracket 81 is mounted on the support frame 1, located between the guide device 3 and the counterweight 5. The first reversing wheel 82 and the second reversing wheel 83 are both rotatably mounted on the adjustment bracket 81. The guide rope 32 can sequentially pass over the first reversing wheel 82 and the second reversing wheel 83, and the first reversing wheel 82 and the second reversing wheel 83 respectively abut against opposite sides of the guide rope 32. Thus, the position and extension direction of the guide rope 32 can be adjusted by the first reversing wheel 82 and the second reversing wheel 83, thereby facilitating the adjustment of the distance between the guide rope 32 and the traction rope 23 on the same horizontal plane. Optionally, the first reversing wheel 82 and the second reversing wheel 83 can also be I-shaped rollers or V-groove rollers.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
