Description

Technical Field

[0001] This utility model relates to a measuring tool for a stacker-reclaimer component, belonging to the field of stacker-reclaimer ring track measurement technology. Background Technology

[0002] Stacker-reclaimers are widely used in bulk cargo unloading scenarios such as bulk cargo terminals, storage yards, and power plants. They mainly consist of a traveling mechanism, a slewing mechanism, a pitching mechanism, a cantilever mechanism, a bucket wheel mechanism, and a tail car mechanism. The slewing mechanism is mainly divided into slewing trolley type and slewing bearing type. This solution is designed for slewing trolley type stacker-reclaimers. The slewing mechanism consists of a drive unit, a slewing trolley, slewing wheels, a slewing track, horizontal wheels, a ring track, and anti-tipping devices. The drive unit drives the slewing wheels to rotate on the slewing track, realizing the slewing action of the stacker-reclaimer. The horizontal wheels rotate along the ring track to prevent the slewing wheels from leaving the track. The ring track deforms due to long-term pressure from the horizontal wheels, causing the slewing wheels to deviate from the track. The method for measuring the ring track of the stacker-reclaimer is to use equipment such as a theodolite and laser rangefinder to find the center of the ring track and then confirm the deformation at various points. However, because there are many steel structures such as the funnel and horizontal wheel support legs in the middle of the ring track, the actual center cannot be accurately measured, leading to inaccurate measurement results. In addition to measurement, existing technologies lack the operator's subjective perception of dimensions and the ability to adapt to different tracks.

[0003] To solve the above problems, this utility model designs a ring rail measuring tool for stacker-reclaimers. By measuring the distance between the ring rail and the rotary track in segments, the relative deformation of the ring rail is finally obtained. Based on the measurement results, the ring rail is repaired so that the distance between the entire ring rail and the rotary track is within a reasonable range, and finally the rotary wheel can operate normally on the rotary track.

[0043] See Figure 1-15 This utility model relates to a measuring tool for a stacker-reclaimer ring track, including a base plate mechanism, a clamping mechanism, a support leg mechanism, a counterweight mechanism, and a rotary track 22. The base plate mechanism includes a base plate 1, an observation line hole, a spirit level 4, and a scale section 17. The observation line hole is located radially outward of the base plate 1 and is used to prevent the observation line 2 from passing through. Fixed through holes 8 are provided on both sides of the outer side of the base plate 1 for installing the clamping mechanism. The base plate 1 also has a blind hole for installing the spirit level 4. The scale section 17 is located radially inward of the base plate 1 and includes a scale and a long slit. The scale is located radially inward of the base plate 1, with a long slit in the middle. The long slit is located along the radial direction of the rotary track 22, which is located outside the ring track 23, which is the track to be measured. The counterweight mechanism is connected to the scale section 17. The base plate 1 moves on the rotary track 22 by clamping the rotary track 22 by two clamping mechanisms, the ring track 23 is measured by a counterweight mechanism, and the base plate 1 is supported by a support leg mechanism.

[0044] Furthermore, the clamping mechanism of this utility model includes a rotating connecting rod 5, a roller rod 6, a roller 7, and a pin. The rotating connecting rod 5 has a hole in the middle and is connected to the fixed through hole 8 in the base plate 1 through the pin. Multiple roller holes 55 are provided at the lower ends of both sides of the rotating connecting rod 5. The upper end of the roller rod 6 is connected to the roller hole 55, and the lower end of the roller rod 6 is connected to the roller 7. The roller 7 can rotate around the roller rod 6.

[0045] Furthermore, the middle elongated hole of the observation line hole is curved, and its radius is consistent with the positioning line of the rotary track 22. The two ends of the observation line hole 2 are round blind holes used to place the observation line post 3. The observation line 2 is curved. By making the observation line coincide with the positioning line, the measurement tool can be accurately and practically used when the clamping mechanism is inconvenient to use in certain positions. At the same time, the observation line 2 can also indirectly observe whether the clamping mechanism is clamped correctly.

[0046] Furthermore, the base plate 1 has two arc-shaped diamond holes to reduce its weight and make it easier to carry.

[0047] Furthermore, the base plate 1 is also provided with leg holes.

[0048] Furthermore, there are three blind holes for the leveling bubble, and there are also three leveling bubbles 4. The leveling bubbles 4 include radial leveling bubbles, tangential leveling bubbles, and leveling bubbles in other directions. The three leveling bubbles 4 are placed in the blind holes for the leveling bubble. The radial leveling bubbles and tangential leveling bubbles are used to adjust the horizontal placement of the base plate 1, and the leveling bubbles in other directions are used to assist in verifying whether the base plate 1 is horizontal.

[0049] Furthermore, the outrigger mechanism includes a base 9, a push block 10, a support frame 11, an upper outrigger 12, a lower outrigger 13, a second pin 14, and a third pin 15. The base 9 includes a horizontal base portion and a vertical base portion. The vertical base portion is located below the horizontal base portion and has four bolt holes for fasteners to connect the base 9 to the outrigger holes on the base plate 1. The vertical base portion has a hinge center hole, which, through the second pin 14, rotatably connects the base 9 to the push block 10. An arc-shaped slide is also provided on the vertical base portion, and the third pin 15 is located within the arc-shaped slide. The support leg is connected to the support frame 11 and push block 10 via pin 15, allowing the support frame 11 and push block 10 to slide along an arc-shaped slide. The arc-shaped slide has slots at both ends to hold pin 15, enabling the leg to fold and unfold. The push block 10 has a central hole for pin 14 to pass through and a radially elongated hole for pin 15 to pass through and slide radially within. By pushing the support frame 11, pin 15 moves radially and slides along the radially elongated hole, thus pushing pin 15 out of the slots at both ends of the arc-shaped slide. This unlocks the pin 15, allowing the outriggers to fold and unfold. Additionally, the push block 10 has a countersunk hole below it, housing a connecting spring. Below the spring is a connecting rod 50. The connecting rod 50 abuts against the support frame 11. Through the connecting spring, the connecting rod 50 pushes the support frame 11, causing the support frame 11 to pull the pin 15 downwards, securing it firmly in the slots at both ends of the arc-shaped slide, thus better maintaining the folding and unfolding of the outriggers. The push block 10 has two arc-shaped grooves on its right side, one above the other, and two arc-shaped grooves on the right side of each groove. The upper support leg 12 has two slots on its side, which are inserted into the arc-shaped slot of the push block 10. The two arc-shaped segments pass through the slots. The upper support leg 12 also has arc-shaped slots on its side, which are further secured with bolts or other fixing methods. The lower part of the upper support leg 12 has external threads for connection with the lower support leg 13, allowing for overall height adjustment. The lower support leg 13 has a deep threaded hole for connection with the upper support leg 12. The lower part of the lower support leg 13 is conical with knurled edges. By adjusting the support height of the support leg mechanism, the levelness of the base plate 1 is adjusted, and the support leg mechanism is supported on the stepped section inside the rotary track 22.

[0050] Furthermore, the counterweight mechanism includes a slider 17, a hanging line 18, a counterweight tail 19, and a counterweight head 20. The slider 17 includes a horizontal part and a vertical part. The horizontal part can slide along the long seam of the base plate 1 and is also provided with a threaded hole with an adjusting screw 21. Tightening the adjusting screw 21 can fix the slider to the base plate 1. The vertical part of the slider 17 has an indicator triangle that can be aligned with a certain scale. The bottom of the vertical part is provided with an I-shaped structure that slides along the long seam of the base plate 1. The bottom of the counterweight tail 19 has a threaded rod, and the top of the counterweight head is provided with a threaded hole. The height of the counterweight head 20 can be adjusted by rotation. Both the counterweight tail 19 and the counterweight head 20 are knurled. The slider 17 is connected to the counterweight tail 19 via the hanging line 18. By sliding the slider 17, the curvature of the ring rail 23 can be marked.

[0051] Furthermore, this utility model also includes an indicating mechanism, which includes a piston rod 40, a left chamber 41, a right chamber 42, a return spring 43, an indicating part 44, and an indicating cylinder 45. The left end of the piston rod 40 is connected to the slider 17, and the right end of the piston rod 40 is disposed in the piston cylinder. The right end of the piston rod 40 is connected to a piston, and the piston is sealed in the piston cylinder, dividing the piston cylinder into a left chamber 41 and a right chamber 42. The indicating cylinder 45 is provided with a left cavity and a right cavity. The bottom of the left cavity is connected to the left chamber 41 through a connecting pipe, and the bottom of the right cavity is connected to the right chamber 42 through a connecting pipe. The bottom of both the left and right cavities is connected to the return spring 43, and the top of the return spring 43 is connected to the indicating part 44. The indicating part 44 can extend out of the indicating cylinder 45, and the indicating parts 44 in the left and right cavities are different colors. After setting the reference for the ring rail 23, the movement of the slider 17 drives the piston rod 40 to move left and right, thereby moving the liquid in the left chamber 41 or right chamber 42 into the left or right cavity. This pushes the indicator 44 in the left or right cavity to extend, indicating the deformation of the ring rail 23. This provides a more intuitive view of the ring rail's deformation and makes it easier for the operator to understand the condition of the ring rail 23. The left and right cavities initially store a portion of liquid to assist in absorbing and replenishing the volume changes of the left and right chambers 41 and 42.

[0052] During use, the clamping roller 7 engages with the edge of the rotary track 22. By observing the level bubble 4, adjust the support legs to level the base plate. Move the slider 17 until the counterweight head 20 contacts the ring track 23, and record the scale corresponding to the slider's indicator triangle. The degree of ring track deformation can be quickly observed through the indicator structure. In locations where the clamping mechanism is inconvenient, an observation line can be used to align the base plate. Draw a center line on the rotary track beforehand; when the observation line coincides with the center line, the base plate's position can be determined. Measure several points along the ring track, and determine the compass repair amount based on the measured wear.

[0053] This utility model is not limited to the embodiments listed above. Any content that falls within the scope of this utility model is considered to be within the protection scope of this utility model.
