Description

Technical Field

[0001] This invention relates to the field of rigid guideway inspection technology, and more specifically, to a rigid guideway inspection device for a mine vertical shaft hoist. Background Technology

[0002] As a key guiding component for the operation of the hoisting container, the rigid guide rail of a mine vertical shaft hoist directly affects the safety and stability of the entire hoisting system through its installation accuracy and deformation during long-term operation. In actual production, due to factors such as installation errors, shaft sway, load changes, and long-term wear, the guide rail inevitably experiences varying degrees of bending, twisting, or uneven joint deformation and displacement. If these deformations are not detected and addressed in time, they will exacerbate the wear between the guide rail and the lugs, leading to problems such as unstable operation of the hoisting container, vibration and abnormal noise, and in severe cases, even major safety accidents such as canister jamming or canister falling.

[0003] Currently, the inspection of rigid tank guideways mainly relies on periodic manual checks or simple automated measuring devices. Manual inspections have limitations such as low efficiency, highly subjective results, high risks associated with working at heights, and difficulty in achieving continuous and comprehensive inspections. Existing automated inspection equipment can mostly only perform displacement measurement in a single direction or static inspection, and lacks sensitivity to minute, localized deformations during tank guideway operation. It is difficult to accurately capture and quantify subtle changes in its spatial posture, especially for minute local bending. Due to the lack of effective amplification and dynamic sensing mechanisms, the weak signals generated are easily ignored, leading to missed detections. This makes it impossible to provide accurate and reliable positioning and severity judgment for preventive maintenance.

[0004] Therefore, existing detection methods are significantly inadequate in terms of comprehensiveness, accuracy, and efficiency. There is a lack of an integrated inspection device that can automatically travel along the tank passage, dynamically sense and amplify the spatial deformation signals of the tank passage, and provide real-time and intuitive identification of the location and severity of defects. Summary of the Invention

[0005] To overcome the above-mentioned technical problems, this invention proposes a rigid guideway inspection device for mine vertical shaft hoists.

[0006] The present invention achieves the above objectives through the following technical solutions: A rigid guideway inspection device for a mine vertical shaft hoist includes an inspection unit and a guideway to be inspected. The inspection unit includes an inspection mechanism, a support frame unit, a battery unit, and a marking assembly. The support frame unit includes a mounting frame, the battery unit is located at the bottom of the mounting frame, and the top of the mounting frame is symmetrically provided with support top plates at both ends. The middle of the support top plate supports an inspection mechanism. The inspection mechanism includes a support roller. The support roller is engaged with the tank track to be inspected and rolls and displaces on the outside of the tank track to be inspected. The inspection mechanism also includes a pressure-sensitive sensing unit. A marking component is provided in the middle of the interior of the mounting frame. The marking component includes two sets of paint can units symmetrically arranged inside the mounting frame. The paint inside the paint tank unit is of a different color and is sprayed onto the outside of the tank channel to be inspected via a spraying component.

[0007] As a further optimization of the present invention, trusses are symmetrically arranged at both ends of the inner side of the mounting frame, and a spray pipe is arranged in the middle of the truss. The interior of the spray pipe is divided into two chambers, and two sets of connecting pipes are arranged at the bottom of the spray pipe, which are respectively connected to the corresponding chambers. The other end of the connecting pipe is respectively connected to the corresponding paint can unit. Several sets of nozzles are evenly arranged at the top of the spray pipe.

[0008] As a further optimization of the present invention, the nozzle sprays the paint inside the paint can unit to the outside of the can channel to be inspected, and controls the spraying of paint from different groups of paint can units by the electrical signal transmitted by the pressure-sensitive sensing unit.

[0009] As a further optimization of the present invention, the inspection mechanism also includes a mounting chassis, which is located in the middle of the top of the supporting top plate on one side away from each other. The top of the mounting chassis supports a disc, and the bottom of the disc is symmetrically provided with two sets of limiting pins. The top of the mounting chassis is provided with a limiting arc groove that is compatible with the limiting pins.

[0010] As a further optimization of the present invention, two sets of fixed support arms are symmetrically arranged on the outer side of the disc along the laying direction of the tank track to be inspected. The fixed support arms are slidably connected to a movable support arm at the end away from the disc. The movable support arms are provided with a support roller at the end away from the fixed support arms. The support roller engages with the tank track to be inspected and rolls on the outer side of the tank track to be inspected.

[0011] As a further optimization of the present invention, the fixed support arm is symmetrically provided with sliding sleeves on both sides near the end of the movable support arm, and the movable support arm is symmetrically provided with support sliding rods penetrating the sliding sleeves on both sides near the end of the fixed support arm. The support sliding rods slide within the sliding sleeves. The top of the movable support arm is provided with a displacement connecting rod near the end of the fixed support arm, and a return spring is provided at the bottom of the displacement connecting rod. The top of the fixed support arm is provided with a limiting groove that matches the return spring.

[0012] As a further optimization of the present invention, pressure-sensitive sensing units are symmetrically arranged on both sides of the top of the support plate. A compression slide rod that passes through the cam is provided on the side of the pressure-sensitive sensing unit near the cam. A through hole that matches the compression slide rod is provided inside the fixed support arm. A compression spring that is fastened to the pressure-sensitive sensing unit is sleeved on the outside of the compression slide rod.

[0013] As a further optimization of the present invention, the limiting pin is limited by the limiting arc groove, thereby driving the disk to deflect and displace, so that the fixed support arm and the movable support arm as a whole can only deflect and displace to both sides, and will not rotate.

[0014] As a further optimization of the present invention, a cam is also provided on the top of the disk, one end of the displacement connecting rod is in contact with the outer side of the cam, a drive shaft is provided in the middle of the bottom of the cam to pass through the disk and the mounting base, a driven gear is provided at the bottom of the drive shaft, the rotation of the drive shaft does not drive the disk to rotate, and a bearing seat is provided between the inside of the mounting base and the drive shaft.

[0015] As a further optimization of the present invention, a mounting shaft is provided in the middle of the bottom of the support top plate, a roller is provided on the top of the outer side of the mounting shaft to roll in contact with the outside of the tank channel to be inspected, and a driving gear is provided at the bottom of the mounting shaft to mesh with the driven gear.

[0016] The beneficial effects of this invention are as follows: 1. This invention achieves reciprocating dynamic adjustment of the support roller spacing through the sliding connection between the movable support arm and the fixed support arm in the inspection mechanism, and with the cooperation of the cam and the displacement linkage. This design cleverly transforms the minute height changes on the same side of the tank passage into amplified longitudinal displacement between the support rollers, significantly improving the device's detection sensitivity to minute deformations such as local bending of the tank passage. The displacement of the movable support arm further drives the fixed support arm to deflect, thereby applying compression or tension to the pressure-sensitive sensing unit. The mechanical deformation is converted into an accurately measurable electrical signal through the spring, ensuring the objectivity and accuracy of the detection data.

[0017] 2. This invention compares the pressure signal received by the pressure-sensitive sensing unit with a preset threshold to intelligently determine the danger level of the can channel deviation and outputs corresponding control commands. These commands drive the paint in the corresponding paint can unit in the marking component to be extracted, transported to the spray pipe via the connecting pipe, and finally sprayed onto the defect location of the can channel to be inspected through the spray nozzle. By using different colored paints stored in different paint can units, the severity of defects is visualized and graded, providing a clear and intuitive basis for positioning and judgment for subsequent manual inspection, greatly improving the pertinence and efficiency of maintenance work.

[0020] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0021] Example 1 like Figures 1 to 11 As shown, a rigid guideway inspection device for a mine vertical shaft hoist includes an inspection unit 10 and a guideway 20 to be inspected. The inspection unit 10 includes an inspection mechanism 100, a support frame unit 200, a battery unit 300, and a marking component 400. The support frame unit 200 includes a mounting frame 201, and the battery unit 300 is located at the bottom of the mounting frame 201. Supporting top plates 203 are symmetrically arranged at both ends of the top of the mounting frame 201. An inspection mechanism 100 is supported in the middle of the supporting top plate 203. The inspection mechanism 100 includes a supporting roller 102. The supporting roller 102 is engaged with the tank passage 20 to be inspected and rolls and moves on the outside of the tank passage 20. The inspection mechanism 100 also includes a pressure-sensitive sensing unit 107. A marking component 400 is provided in the middle of the interior of the mounting bracket 201. The marking component 400 includes two sets of paint can units 404 symmetrically arranged inside the mounting bracket 201. The mounting bracket 201 has symmetrically arranged trusses 202 at both ends on its inner side. A spray pipe 401 is arranged in the middle of the truss 202. The spray pipe 401 is divided into two chambers, and the bottom of the spray pipe 401 is provided with two sets of connecting pipes 403 that are respectively connected to the corresponding chambers. The other end of the connecting pipes 403 is respectively connected to the corresponding paint can unit 404. Several sets of spray nozzles 402 are evenly arranged on the top of the spray pipe 401. The paint inside the paint can unit 404 has a different color and is sprayed onto the outside of the can channel 20 to be inspected through the spraying assembly. The nozzle 402 sprays the paint inside the paint can unit 404 to the outside of the can channel 20 to be inspected, and controls the spraying of paint from different groups of paint can units 404 through the electrical signal transmitted by the pressure-sensitive sensing unit 107. The inspection mechanism 100 also includes a mounting chassis 103. The mounting chassis 103 is located in the middle of the top of the support plate 203, on one side away from each other. The top of the mounting chassis 103 supports a disc 117. Two sets of limiting pins 121 are symmetrically arranged at the bottom of the disc 117. The top of the mounting chassis 103 is provided with a limiting arc groove 104 that is compatible with the limiting pins 121. Two sets of fixed support arms 118 are symmetrically arranged on the outer side of the disc 117 along the laying direction of the tank passage 20 to be inspected. The end of the fixed support arm 118 away from the disc 117 is slidably connected to a movable support arm 101. The end of the movable support arm 101 away from the fixed support arm 118 is provided with a support roller 102. The support roller 102 engages with the tank passage 20 to be inspected and rolls on the outer side of the tank passage 20 to be inspected. A sliding sleeve 114 is symmetrically arranged on both sides of the fixed support arm 118 near the movable support arm 101. A support slide rod 115, penetrating the sliding sleeve 114, is symmetrically arranged on both sides of the movable support arm 101 near the fixed support arm 118. The support slide rod 115 slides within the sliding sleeve 114. A displacement connecting rod 116 is arranged at the top of the movable support arm 101 near the fixed support arm 118. A return spring 119 is arranged at the bottom of the displacement connecting rod 116. A limiting groove 120, matching the return spring 119, is arranged at the top of the fixed support arm 118. The top of the support plate 203... Pressure-sensitive sensing units 107 are symmetrically arranged on both sides of the cam 108. A pressure-sensitive sensing unit 107 is provided with a pressing slide rod 105 that passes through the cam 108 on the side near the cam 108. The fixed support arm 118 is provided with a through hole 122 that matches the pressing slide rod 105. A pressing spring 106 that is fastened to the pressure-sensitive sensing unit 107 is sleeved on the outside of the pressing slide rod 105. The limiting pin 121 is limited by the limiting arc groove 104, which in turn drives the disc 117 to deflect and move, keeping the fixed support arm 118 and the movable support arm 101 as a whole only able to deflect and move to both sides, and not rotate. A cam 108 is also provided on the top of the disc 117. One end of the displacement connecting rod 116 is in contact with the outer side of the cam 108. A drive shaft 109 is provided in the middle of the bottom of the cam 108, which passes through the disc 117 and the mounting base 103. A driven gear 110 is provided at the bottom of the drive shaft 109. The rotation of the drive shaft 109 does not drive the disc 117 to rotate. A bearing seat is provided between the inside of the mounting base 103 and the drive shaft 109. A mounting shaft 113 is provided in the middle of the bottom of the support top plate 203. A roller 112 is provided on the top of the outer side of the mounting shaft 113, which is in contact with the outside of the tank passage 20 to be inspected and rolls. A drive gear 111 is provided at the bottom of the mounting shaft 113, which meshes with the driven gear 110.

[0022] The usage process of the rigid guideway inspection device for mine vertical shaft hoisting proposed in this embodiment is as follows: when the device is in use, four sets of support rollers 102 are symmetrically distributed and engaged with the outside of the guideway 20 to be inspected, thus completing the assembly of the inspection unit 10 with the guideway 20 to be inspected. Furthermore, by connecting the mounting bracket 201 to an external displacement driving device, which can be any type of displacement device in the prior art, the specific details will not be elaborated here. An external displacement drive device drives the mounting frame 201 to slide and move on the outside of the tank channel 20 to be inspected. During the rolling displacement of the support roller 102 against the inspection tank channel 20, the mounting shaft 113 synchronously rolls against the outer side of the inspection tank channel 20, thereby driving the coaxially mounted drive gear 111 to rotate. The rotation of the drive gear 111 further drives the driven gear 110 to follow and mesh, and the rotation of the driven gear 110 in turn drives the cam 108 to rotate. The rotation of cam 108 causes the displacement link 116 that is in contact with it to be subjected to the squeezing force from the outside of cam 108. The displacement link 116 is limited by the sliding sleeve 114 and the support slide rod 115, so that the displacement link 116 can only move in the horizontal direction. Then, the displacement link 116 drives the movable support arm 101 to move as a whole. The displacement of the movable support arm 101 causes the distance between the two sets of support rollers 102 on the same side to change. During the inspection of the tank passage 20 under inspection by the inspection unit 10, the distance between the two sets of support rollers 102 on the same side is repeatedly adjusted. When the distance between the two sets of support rollers 102 on the same side increases, it can increase the offset distance of the offset height at both ends of the tank passage 20 under inspection, thereby increasing the longitudinal displacement distance between the two sets of support rollers 102 on the same side. The displacement of the support roller 102 changes, which in turn causes the fixed support arm 118 connected to the movable support arm 101 to deflect synchronously, so that the fixed support arm 118 causes the two sets of springs 106 on both sides to undergo two changes of tension and compression. The compressed set of springs 106 exerts pressure on the pressure-sensitive sensing unit 107, causing the pressure-sensitive sensing unit 107 to receive the pressure and convert it into an electrical signal. The pressure sensor unit 107 judges the magnitude of the pressure and compares it with a pre-set threshold to determine the degree of danger of the deviation of the tank channel 20 under inspection. It then sends an electrical signal to control the corresponding set of paint tank units 404 to extract the paint inside, which is then transported to the inside of the spray pipe 401 through the connecting pipe 403 and sprayed out from the corresponding nozzle 402 position. The position where the tank channel 20 under inspection has deviated is marked to facilitate manual positioning and maintenance later. By controlling different paint can units 404 to spray different colors of paint, it is easier for maintenance personnel to determine the degree of displacement of the area and provide a basis for judgment. As the cam 108 continues to rotate, when the cam 108 stops pressing one end of the displacement link 116, the movable support arm 101 is driven to reset and move closer to the fixed support arm 118 under the action of the rebound force of the limit slider 119, thereby causing the two sets of support rollers 102 to move closer to each other. By continuously adjusting the distance of the support rollers 102 during the overall displacement of the inspection unit 10 on the outside of the tank channel 20 to be inspected, the degree of offset in different areas on the outside of the tank channel 20 to be inspected is more comprehensively detected, thus optimizing the problem that the existing offset detection process cannot accurately measure the offset due to the small offset angle.

[0023] The specific implementation methods of the embodiments of the present invention have been described above. However, the embodiments of the present invention are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments of the present invention, all of which are within the protection scope of the embodiments of the present invention.
