Description

Technical Field

[0001] This utility model relates to the field of hoisting platform stabilization technology, specifically to a hoisting platform stabilization device for vertical shafts. Background Technology

[0002] The shaft hoisting platform is an important tool platform for shaft construction in mining. It is named for the platform suspended in the shaft. The shaft hoisting platform is the main working platform for building the shaft wall and also the operating platform for installing permanent equipment in the shaft, such as guideways, guideway beams, permanent pipelines, ladders, etc. It is a safety protection barrier for personnel at the shaft working face. The upper platform is generally used as a protective platform to prevent falling objects from the shaft from injuring personnel at the working face.

[0003] In vertical shafts, the hoisting platform is typically raised and lowered by controlling the raising and lowering of the wire rope using a hoisting winch. However, since the wire rope is a flexible material, the hoisting platform is prone to tilting and swaying during the raising and lowering process in the vertical shaft. This can cause the hoisting platform to collide with the shaft wall, potentially leading to safety accidents. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a vertical shaft hoisting platform stabilization device, which solves the technical problem that the hoisting platform is prone to tilting during the lifting and lowering process in the vertical shaft, thus affecting the lifting and lowering stability.

[0005] According to one aspect, at least one embodiment of the present invention provides a vertical shaft hoisting platform stabilization device, including mounting blocks, wherein multiple mounting blocks are fixedly disposed between adjacent sidewalls of the vertical shaft hoisting platform, and further including a limiting frame, limiting wheels, mounting plates, and a position adjustment mechanism. The limiting frame is disposed on one side of the mounting block, and multiple limiting wheels are rotatably disposed within the limiting frame. The mounting plates are fixedly disposed at both ends of the sidewall of the mounting block, and threaded holes are provided on the mounting plates. The position adjustment mechanism is disposed between the limiting frame and the mounting blocks for adjusting the position of the limiting frame.

[0006] Preferably, the position adjustment mechanism includes a limiting groove, a limiting block, and an angle adjustment mechanism. The limiting groove is formed on the side wall of the mounting block near the limiting frame. Two limiting blocks are arranged between the limiting frame and the bottom of the limiting groove. The two ends of the limiting blocks are hinged to the limiting frame and the bottom of the limiting groove, respectively, through hinge seats. The angle adjustment mechanism is arranged between the mounting block and the limiting blocks for adjusting the angle of the limiting blocks.

[0007] Furthermore, the angle adjustment mechanism includes an adjustment groove, an adjustment seat, a threaded rod, and a rotation mechanism. The adjustment groove is formed on the side wall of the mounting block near the limiting frame. The adjustment seat is slidably disposed in the adjustment groove. An adjustment block is hinged between the adjustment seat and the adjacent limiting block. The threaded rod is rotatably disposed in the adjustment groove and passes through the adjustment seat through a threaded engagement. The rotation mechanism is disposed on the mounting block and is used to drive the threaded rod to rotate.

[0008] Furthermore, the rotating mechanism includes a first cavity, a second bevel gear, and a driving mechanism. The first cavity is formed within the mounting block. The first bevel gear is rotatably mounted on the inner top wall of the first cavity. The first bevel gear is fixedly connected to the threaded rod. The second bevel gear is rotatably mounted on the inner wall of the first cavity and meshes with the first bevel gear. The driving mechanism is mounted on the mounting block and is used to drive the second bevel gear to rotate.

[0009] Furthermore, the drive mechanism includes a first housing, a handwheel, and a positioning mechanism. A cylindrical first housing is rotatably disposed through the side wall of the first cavity. The first housing is fixedly connected to the second bevel gear. The handwheel is disposed on one side of the first housing. The positioning mechanism is disposed between the handwheel and the first housing for positioning the handwheel and the first housing.

[0010] Based on the above scheme, the positioning mechanism includes a positioning port, a positioning groove, a positioning block, and a positioning post. The positioning port is opened on the side wall of the first housing away from the mounting block. The positioning groove is opened on the side wall of the first housing close to the mounting block. The positioning block is disposed inside the first housing and its shape is adapted to the positioning groove. The positioning post is disposed through the positioning port, and its two ends are fixedly connected to the handwheel and the positioning block, respectively.

[0011] Based on the above scheme, a support spring is fixedly provided at the bottom of the positioning groove, and the support spring abuts against the positioning block.

[0012] Based on the above scheme, a rubber pad is fixedly provided on the side wall of the limiting wheel.

[0013] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, by setting up a position adjustment mechanism, the operation of the rotating mechanism can drive the threaded rod to rotate. At the same time, the threaded rod and the threaded engagement of the adjusting seat can drive the adjusting seat to move. Then, the position of the limiting block can be adjusted by the adjusting block on the adjusting seat. Thus, the position of the limiting frame and the limiting wheel can be adjusted by adjusting the angle of the limiting block. This ensures that the limiting wheel and the side wall of the shaft are kept in contact during the lifting and lowering of the shaft platform. This facilitates the anti-tilting effect of the shaft platform by the contact of multiple limiting wheels with the side wall of the shaft. 2. In this utility model, through the setting of the drive mechanism, the positioning block can be inserted into the positioning groove by pushing the handwheel through the positioning pin. Then, the rotation of the handwheel can drive the first housing and the second bevel gear to rotate through the cooperation of the positioning block and the positioning groove. At the same time, the threaded rod can be driven to rotate through the meshing of the second bevel gear and the first bevel gear. After the position adjustment of the limit wheel is completed, the handwheel is released, and the positioning block can be pushed out of the positioning groove under the elastic force of the support spring, thereby avoiding the position of the limit wheel from being displaced due to accidental contact with the handwheel. 3. In this utility model, the combination of the limiting frame, limiting wheel, limiting block, and hinge seat, along with the adjustment functions of the adjusting groove, adjusting seat, adjusting block, and threaded rod, can achieve adaptive adaptation to vertical shaft environments with different dimensional deviations and sidewall shapes, and can stably perform the limiting function without additional modifications. The rubber pad of the limiting wheel and the buffering characteristics of each adjusting component work together to effectively weaken the rigid impact when in contact with the vertical shaft sidewall, reducing wear on both sides and reducing operating vibration. The protective structure of the first cavity, the first shell, and the adjusting groove works together to isolate the erosion of core transmission components such as the first bevel gear, the second bevel gear, and the threaded rod by downhole dust, water, and other impurities. Combined with the friction loss reduction characteristics of the hinge seat, it significantly extends the overall service life of the device. The positioning drive structure composed of the handwheel, positioning groove, positioning block, positioning column, and support spring works together with the thread self-locking characteristics of the threaded rod to reduce the adjustment resistance of the operator, improve the convenience of operation, and reliably avoid position deviation caused by accidental touch, ensuring the stability of the adjusted state.

[0022] like Figures 1-5 As shown, this invention illustrates a shaft hoisting platform stabilizing device according to an embodiment of the present invention. It includes mounting blocks 3, with multiple mounting blocks 3 fixedly disposed between adjacent sidewalls of the shaft hoisting platform. It also includes a limiting frame 5, limiting wheels 6, mounting plates, and a position adjustment mechanism. A limiting frame 5 is provided on one side of each mounting block 3, and multiple limiting wheels 6 are rotatably disposed within the limiting frame 5. Mounting plates are fixedly disposed at both ends of the sidewall of each mounting block 3, and threaded holes are provided on the mounting plates. The position adjustment mechanism is disposed between the limiting frame 5 and the mounting block 3 for adjusting the position of the limiting frame 5. Rubber pads are fixedly disposed on the sidewalls of the limiting wheels 6.

[0023] Reference Figure 1 and Figure 2The position adjustment mechanism includes a limiting groove 7, a limiting block 8, and an angle adjustment mechanism. A limiting groove 7 is formed on the side wall of the mounting block 3 near the limiting frame 5. Two limiting blocks 8 are arranged between the limiting frame 5 and the bottom of the limiting groove 7. The two ends of the limiting blocks 8 are hinged to the limiting frame 5 and the bottom of the limiting groove 7 respectively via hinge seats 9. The angle adjustment mechanism is located between the mounting block 3 and the limiting blocks 8, and is used to adjust the angle of the limiting blocks 8. The angle adjustment mechanism includes an adjustment groove 10, an adjustment seat 11, a threaded rod 13, and a rotation mechanism. The adjustment groove 10 is formed on the side wall of the mounting block 3 near the limiting frame 5. The adjustment seat 11 is slidably disposed within the adjustment groove 10. An adjustment block 12 is hinged between the adjustment seat 11 and the adjacent limiting block 8. The threaded rod 1... 3. The rotating mechanism is set in the adjusting groove 10. The threaded rod 13 passes through the adjusting seat 11 through the threaded engagement. The rotating mechanism is set on the mounting block 3 and is used to drive the threaded rod 13 to rotate. Specifically, the operation of the rotating mechanism can drive the threaded rod 13 to rotate. At the same time, the threaded engagement between the threaded rod 13 and the adjusting seat 11 drives the adjusting seat 11 to move. Then, the adjusting block 12 on the adjusting seat 11 can realize the position adjustment of the limiting block 8. Thus, the position of the limiting frame 5 and the limiting wheel 6 can be adjusted by adjusting the angle of the limiting block 8. This ensures that the limiting wheel 6 is in contact with the side wall of the shaft during the lifting and lowering process in the shaft. It is convenient to achieve the anti-tilt effect of the shaft lifting platform by the contact between multiple limiting wheels 6 and the side wall of the shaft.

[0024] It should also be noted that both ends of the threaded rod 13 are fitted with elastic telescopic tubes, and the two ends of the elastic telescopic tubes are fixedly connected to the side wall of the adjusting groove 10 and the side wall of the adjusting seat 11, respectively.

[0025] The limiting frame 5, while providing stable support for the limiting wheel 6, can further adapt to minute radial dimensional deviations at different depths within the shaft through its hinged engagement with the limiting block 8. By slightly buffering its own stress deformation, it reduces the rigid impact when the limiting wheel 6 contacts the shaft sidewall, indirectly improving the overall stress stability of the stabilizing device and lowering the risk of structural fatigue after long-term use. A buffer pad can be installed on the hinge shaft to prevent shaft breakage and damage caused by rigid impacts.

[0026] The limiting wheel 6, together with the rubber pad fixed to its side wall, not only prevents tilting, but also fills the minor unevenness of the shaft side wall with its own elasticity, making the contact between the limiting wheel 6 and the side wall more closely fit, avoiding damage to the side wall caused by local stress concentration; at the same time, the rolling friction characteristics can further reduce the energy consumption during the lifting of the hoist platform, reduce the load pressure on the hoist, and the presence of the rubber pad can effectively weaken the vibration transmission generated during the lifting process, improving the stability of the hoist platform operation.

[0027] In addition to providing installation and movement space for the limit block 8, the limit groove 7 can precisely guide the rotation trajectory of the limit block 8, preventing lateral deviation of the limit block 8 during angle adjustment. This ensures that the adjustment direction of the limit frame 5 and the limit wheel 6 always points towards the side wall of the shaft, improving the accuracy of position adjustment. At the same time, the groove can protect the connection between the limit block 8 and the mounting block 3, reducing the erosion of the hinge structure by dust, gravel and other impurities in the well, and extending the service life of the components.

[0028] The limiting block 8, with the cooperation of the hinged seats 9 at both ends, allows the angle adjustment flexibility of the stabilizing plate device to adapt to the slight taper or local curvature changes of the shaft sidewall. It can be adapted to different working conditions of the shaft environment without additional modification to the device. At the same time, the symmetrical arrangement of the two limiting blocks 8 can make the limiting frame 5 more evenly stressed, avoid uneven wear of the limiting wheel 6 caused by unilateral stress, and improve the overall service life of the device.

[0029] The hinge seat 9's rotational connection characteristics can reduce the relative frictional loss between the limit block 8, the limit frame 5, and the limit groove 7, reduce the operating resistance during the adjustment process, and make it easier for operators to complete the position adjustment of the limit wheel 6 with less effort; at the same time, the gap of the hinge structure can be automatically compensated by its own wear, avoiding jamming problems caused by long-term use and improving the reliability of the device adjustment.

[0030] While providing sliding guidance for the adjustment seat 11, the adjustment groove 10, in conjunction with the elastic telescopic tube, can prevent mud, sand, and water from entering the threaded engagement part of the threaded rod 13 and the adjustment seat 11, avoiding thread corrosion or jamming, and ensuring the smooth operation of the position adjustment mechanism over a long period of time. In addition, the length design of the adjustment groove 10 can limit the travel of the adjustment seat 11, avoiding excessive adjustment that could cause excessive pressure between the limit wheel 6 and the shaft sidewall, and protecting the rubber pad and shaft sidewall from damage.

[0031] The threaded engagement between the adjusting seat 11 and the threaded rod 13 enables fine-tuning of the position of the limiting wheel 6. Its sliding stability ensures that the height and horizontal position of the limiting wheel 6 do not shift during the adjustment process, further improving the accuracy of the anti-tilt mechanism. At the same time, the hinged engagement between the adjusting seat 11 and the adjusting block 12 can resolve the lateral stress during the adjustment process, preventing deformation and damage to the components due to uneven force.

[0032] The adjusting block 12 serves as the transmission medium between the adjusting seat 11 and the limiting block 8. Its hinged structure can adapt to the angle changes between the two, making the linear drive of the threaded rod 13 more smoothly converted into the angular rotation of the limiting block 8, and reducing energy loss in the power transmission process. At the same time, the length design of the adjusting block 12 can optimize the force transmission path, improve the transmission efficiency of the adjusting mechanism, and make the adjustment operation of the operator less strenuous.

[0033] The high-precision characteristics of the threaded rod 13 enable precise control of the position of the limit wheel 6, ensuring that the contact force between the multiple limit wheels 6 and the side wall of the shaft remains consistent, thus avoiding the tilting of the hoisting platform due to uneven contact force. At the same time, the threaded drive has a self-locking characteristic, which can maintain the position of the adjusting seat 11 by means of its own thread friction after adjustment, thereby assisting the positioning mechanism in improving the anti-accidental contact effect and further ensuring the safe operation of the hoisting platform.

[0034] Reference Figures 3-5 The rotating mechanism includes a first cavity 14, a second bevel gear 16, and a driving mechanism. The first cavity 14 is located within the mounting block 3. A first bevel gear 15 is rotatably mounted on the inner top wall of the first cavity 14 and is fixedly connected to a threaded rod 13. The second bevel gear 16 is rotatably mounted on the inner wall of the first cavity 14 and meshes with the first bevel gear 15. The driving mechanism is mounted on the mounting block 3 and is used to drive the second bevel gear 16 to rotate. The driving mechanism includes a first housing 17, a handwheel 18, and a positioning mechanism. A cylindrical first housing 17 is rotatably mounted through the side wall of the first cavity 14 and is fixedly connected to the second bevel gear 16. The handwheel 18 is located on one side of the first housing 17. The positioning mechanism is located between the handwheels 18 and is used to position the handwheel 18 and the first housing 17. The positioning mechanism includes a positioning port, a positioning groove 19, a positioning block 20, and a positioning post 21. The positioning port is located on the side wall of the first housing 17 away from the mounting block 3. The positioning groove 19 is formed on the side wall of the first housing 17 near the mounting block 3. The positioning block 20 is set inside the first housing 17 and its shape is adapted to the positioning groove 19. The positioning post 21 is set through the positioning opening. The two ends of the positioning post 21 are fixedly connected to the handwheel 18 and the positioning block 20, respectively. A support spring 22 is fixedly set at the bottom of the positioning groove 19 and abuts against the positioning block 20. Specifically, by pushing the handwheel 18, the positioning block 20 can be inserted into the positioning groove 19 through the positioning post 21. Then, the rotation of the handwheel 18 can drive the first housing 17 and the second bevel gear 16 to rotate through the cooperation of the positioning block 20 and the positioning groove 19. At the same time, the engagement of the second bevel gear 16 and the first bevel gear 15 can drive the threaded rod 13 to rotate. After the position adjustment of the limit wheel 6 is completed, the handwheel 18 is released. Under the elastic force of the support spring 22, the positioning block 20 can be pushed out of the positioning groove 19, thereby avoiding the position of the limit wheel 6 from being displaced due to accidental contact with the handwheel 18.

[0035] Moreover, the first cavity 14 provides a sealed installation space for the first bevel gear 15 and the second bevel gear 16, which can effectively isolate the harsh environment downhole, prevent impurities from entering the meshing parts of the bevel gears and causing accelerated wear, and extend the service life of the rotating mechanism; at the same time, the cavity structure can reduce the transmission of noise generated when the bevel gears rotate, and improve the downhole working environment.

[0036] The meshing transmission of the first bevel gear 15 and the second bevel gear 16 can achieve a 90° change in the power direction, allowing the operator to adjust the drive of the threaded rod 13 from the side of the mounting block 3 without having to operate from the top or bottom of the hoisting platform, thus improving the convenience and safety of operation; at the same time, the bevel gear transmission has a strong load-bearing capacity, which can adapt to the load requirements under complex working conditions downhole and ensure the stability of power transmission.

[0037] The fixed connection between the second bevel gear 16 and the first housing 17 enables the power transmission of the drive mechanism to be more direct, reducing energy loss in the intermediate transmission links; at the same time, the meshing of the double bevel gears makes the rotation adjustment smoother, avoids jerking, improves the operator's adjustment feel, and facilitates precise control of the position of the limit wheel 6.

[0038] In addition to being fixedly connected to the second bevel gear 16, the cylindrical structure of the first housing 17 can protect the internal positioning mechanism (positioning block 20, positioning post 21, etc.) to prevent impurities from entering and affecting the positioning effect. At the same time, the rotational cooperation between the first housing 17 and the mounting block 3 can reduce the frictional resistance during rotation, improve the smoothness of the drive mechanism's rotation, and the housing structure can prevent operators from directly contacting the internal transmission components, reducing safety risks during operation.

[0039] The handwheel 18's user-friendly design improves the operator's adjustment efficiency, allowing for position adjustment of the limit wheel 6 without the need for additional tools, thus meeting the needs of emergency adjustment downhole. At the same time, the fixed connection between the handwheel 18 and the positioning column 21 ensures the reliability of power transmission, avoids slippage during adjustment, and improves operational stability.

[0040] In addition to preventing accidental touches, the matching design of the positioning groove 19 and the positioning block 20 ensures the positioning accuracy of the positioning block 20 when it is inserted, so that the rotation power of the handwheel 18 can be accurately transmitted to the first housing 17, avoiding adjustment errors caused by power transmission deviation; at the same time, the depth design of the positioning groove 19 can limit the insertion stroke of the positioning block 20, avoiding damage to the components due to over-insertion.

[0041] The insertion and removal of the positioning block 20 with the positioning groove 19 enables the drive mechanism to start and stop quickly, allowing the operator to lock the adjustment state in time after adjustment, thus improving operating efficiency. At the same time, the structural strength of the positioning block 20 ensures that it will not deform during power transmission, guaranteeing the long-term stable operation of the drive mechanism. Furthermore, the fixed connection between the positioning block 20 and the positioning column 21 prevents relative sliding between the two, improving the reliability of the positioning mechanism.

[0042] The positioning post 21 serves as the connecting medium between the handwheel 18 and the positioning block 20. Its rigid structure ensures the accuracy of power transmission and avoids power loss during adjustment. At the same time, the design of the positioning post 21 penetrating through the first housing 17 guides the movement of the positioning block 20, ensuring that the positioning block 20 can accurately embed or dislodge from the positioning groove 19, thereby improving the operational stability of the positioning mechanism.

[0043] In addition to enabling the automatic disengagement of the positioning block 20, the elastic restoring function of the support spring 22 allows the spring force to be adapted according to actual needs, ensuring that the force when the positioning block 20 disengages is moderate. This avoids the positioning block 20 failing to disengage completely due to insufficient spring force, and also prevents excessive spring force from causing the operator to exert too much effort when pushing the handwheel 18. At the same time, the fatigue resistance of the support spring 22 ensures that it can maintain stable elastic performance after long-term use, reducing the maintenance frequency and cost of the device.

[0044] In this embodiment, during use, the operator can use bolts to penetrate the mounting plate and the panel to fix multiple mounting blocks between the side walls of the panel. Afterwards, using a lift, the vertical shaft platform is extended into the vertical shaft. The operator then pushes the handwheel 18, which, through the positioning pin 21, extends the positioning block 20 into the positioning groove 19. The rotation of the handwheel 18, through the engagement of the positioning block 20 and the positioning groove 19, drives the first housing 17 and the second bevel gear 16 to rotate. Simultaneously, the meshing of the second bevel gear 16 and the first bevel gear 15 drives the threaded rod 13 to rotate. The threaded engagement of the threaded rod 13 with the adjusting seat 11 causes the adjusting seat 11 to move. The position of the limiting block 8 is adjusted by adjusting the adjusting block 12 on the adjusting seat 11. The position of the limiting frame 5 and the limiting wheel 6 can be adjusted by adjusting the angle of the limiting block 8. This ensures that the limiting wheel 6 remains in contact with the side wall of the shaft during the lifting and lowering process. The contact between the multiple limiting wheels 6 and the side wall of the shaft facilitates the anti-tilt effect of the shaft hoist. After the position of the limiting wheel 6 is adjusted, the operator can release the handwheel 18. At this time, under the elastic force of the support spring 22, the positioning block 20 can be pushed out of the positioning groove 19, thereby avoiding the position of the limiting wheel 6 from being displaced due to accidental contact with the handwheel 18.
