Description

Technical Field

[0001] The present invention relates to the technical field of mine hoisting, and in particular to a vertical shaft hoisting container replacement device and a replacement method. Background Art

[0002] Replacing the hoist container of a shaft hoist has always been a major challenge in shaft maintenance in the mining industry. Currently, the hoist container is often replaced by directly lifting it with a crane. This operation method poses significant safety risks, and it also leads to long maintenance times, low maintenance efficiency, high labor intensity for operators, and impacts production operations. Furthermore, when replacing the tail rope, the weight of the tail rope is entirely supported by a hand chain hoist, further increasing the labor intensity of operators.

[0003] Prior art patent application number CN108516450A discloses a method for quickly replacing large skips in coal mines. When replacing an old skip with a new one, a lifting device is used to lift the old skip to assist in the replacement. Prior art methods use lifting equipment to lift the skip, which can easily cause the skip to shake during the lifting process, posing a safety hazard. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to solve the problem that when replacing the old lifting container with the new one, the old lifting container is replaced by the lifting equipment, which poses a safety hazard, and when the tail rope is disassembled and assembled from the old lifting container to the new lifting container, the entire weight of the tail rope is borne by the hand winch, which increases the labor intensity of the operators.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A vertical shaft lifting container replacement device includes a beam frame 100, a flatbed transport vehicle 200 capable of autonomous movement on the beam frame 100, a pair of mutually offset retracting and unfolding devices 300 located within the beam frame 100, a tail rope buckle 400 movably connected to the retracting and unfolding devices 300, and a sunken platform 500 detachably connected to the beam frame 100.

[0007] Advantages: By using a tail rope clip to clamp the tail rope of the lifting container, the tail rope clip and the tail rope are raised or lowered when replacing the old lifting container with the new one through the retractable device. This replaces the traditional manual winch and manual coordination mode, which can reduce the labor intensity of the operators and improve the replacement efficiency. When replacing the old lifting container with the new one, the flatbed transport vehicle moves autonomously on the beam frame to carry the new and old lifting containers. In this way, the lifting container's own lifting system can be used. The flatbed transport vehicle autonomously moves to the wellhead position. The lifting container's own lifting system places the old lifting container on the flatbed transport vehicle. After disassembly, it is transported out of the wellhead position and the new lifting container is transported to the wellhead. After the flatbed transport vehicle connects the lifting system to the new lifting container, the flatbed transport vehicle moves away from the wellhead. The replacement of the old and new lifting containers is completed. No other lifting device is required. Only the lifting container's own lifting system and the flatbed transport vehicle are used to complete the replacement of the old and new lifting containers. Compared with the method of using lifting equipment, it is safer and there is no problem of the hoisted lifting container dangling in the air.

[0035] To facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described with reference to the accompanying drawings.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0037] See also Figure 1As shown, the present invention provides a vertical shaft lifting container replacement device, including a beam frame 100, and a flatbed transport vehicle 200 that can move autonomously on the beam frame 100, a pair of mutually staggered retracting and extending devices 300 located in the beam frame 100, a tail rope buckle 400 movably connected to the retracting and extending devices 300, and a sunken platform 500 detachably connected to the beam frame 100.

[0038] See also Figure 1 As shown, in one embodiment of the present invention, the beam frame 100 includes a pair of square tubes 110 and a plurality of cross beams 120. The pair of square tubes 110 are fixedly connected by the plurality of cross beams 120, and the vertical distance between the pair of square tubes 110 is greater than the diameter of the shaft. The beam frame 100 also includes a coupling 130, which is fixed on the opposite sides of the pair of square tubes 110, and a track 111 is provided on the top of the pair of square tubes 110. The coupling 130 and the track 111 cooperate with the flatbed transport vehicle 200, so that the flatbed transport vehicle 200 can move autonomously along the track 111 on the pair of square tubes 110. However, when the lifting container needs to be replaced, the beam frame 100 is placed at the shaft, and the shaft is located between the pair of square tubes 110, and the plurality of cross beams 120 do not block the shaft mouth. Wherein, the shaft lifting container replacement device also includes a reinforcing rib 600 (see Figure 4 As shown in FIG, a plurality of reinforcing ribs 600 are respectively located on the inner walls of a pair of square tubes 110 to enhance the load-bearing capacity of the beam frame 100. The rails 111 are welded to the square tubes 110 to withstand a greater weight load.

[0039] Please refer to 1 to Figure 3 As shown, in one embodiment of the present invention, a flatbed transport vehicle 200 can carry new and old lifting containers and travel along a track 111. The vehicle comprises a support plate 210, a wheel follower assembly 220, and a power assembly 230. The support plate 210 is fixedly positioned above the wheel follower assembly 220 and does not hinder the movement of the wheel follower assembly 220. The power assembly 230 is fixedly connected to the bottom surface of the support plate 210. The power assembly 230 provides power, enabling the wheel follower assembly 220 to move along the track 111 with the support plate 210. The power assembly 230 comprises a motor 231 and a gear 232. The motor 231 is fixedly connected to the support plate 210 and is located on the bottom surface of the support plate 210. The gear 232 is fixedly connected to the output end of the motor 231 and meshes with the meshing member 130. The motor 231 provides power, and its output end drives the gear 232 to mesh with the meshing member 130, thereby driving the wheel follower assembly 220 to move along the track 111. The number of the power components 230 is, for example, multiple, which can provide greater power.

[0040] Please refer to 1 to Figure 4As shown, in one embodiment of the present invention, a pair of retractable devices 300 are respectively disposed within a pair of square tubes 110 and are horizontally offset from each other. The retractable devices 300 are used to hoist the tail rope, ensuring safer and more convenient contact and connection between the tail rope and the lifting container. The retractable devices 300 include a cylinder 310 and a push sprocket 320. The cylinder base of the cylinder 310 is fixed within the square tube 110. The push sprocket 320 is disposed at the output end of the cylinder 310. The output end of the cylinder 310 is telescopically linked to drive the push sprocket 320 to move horizontally within the square tube 110. The retractable devices 300 also include a first redirecting sprocket 330, a second redirecting sprocket 340, and a chain 350. The first redirecting sprocket 330 is located at the bottom of the inner wall of the square tube 110, while the second redirecting sprocket 340 is located at the top of the inner wall of the square tube 110. The first and second redirecting sprockets 330, 340 are horizontally offset from each other. The head end of chain 350 passes through the bottom of square tube 110 and rests on first redirecting sprocket 330. It then redirects via first redirecting sprocket 330 to push sprocket 320, then onto second redirecting sprocket 340. Finally, it passes through second redirecting sprocket 340, redirects, and passes through the bottom of square tube 110, where it is flush with its end. The output end of oil cylinder 310 extends, pushing push sprocket 320, causing the head and tail of chain 350 to rise synchronously. The output end of oil cylinder 310 retracts, driving push sprocket 320 to retract, causing the head and tail of chain 350 to descend synchronously. In this embodiment, chain 350 is a round link chain, and the single-ended breaking load of chain 350 is 610 to 820 kN. The total breaking load of double-ended chain 350 can reach 1200 to 1600 kN. The sprockets for the push sprocket 320, the first redirecting sprocket 330, and the second redirecting sprocket 340 are made of a chromium-molybdenum alloy. After a tempering process, these alloys exhibit excellent recoil and wear resistance. The sprocket bearings utilize high-strength needle roller bearings, providing high load capacity and flexible rotation. The retraction and retraction device 300 utilizes a hydraulic chain retraction method, enabling efficient and safe raising and lowering of the tail rope.

[0041] See 1 and Figure 4As shown, in one embodiment of the present invention, a tail rope buckle 400 is movably connected to the head and tail ends of the chain 350 to secure the tail rope. The tail rope buckle 400 includes a locking buckle 410, a connecting piece 420, and a snap plate 430. A pair of locking buckles 410 are respectively interlocked with the head and tail ends of the chain 350 and then connected to one end of a pair of connecting pieces 420. The snap plates 430 are provided with lugs 431 on either side of their tops, each with a fixing hole 432. The snap plates 430 are also longitudinally arranged with multiple rows of clamping holes 433 in two rows, with a clamping area 434 located between the two rows of clamping holes 433. The connecting piece 420 is located between the pair of snap plates 430 and is detachably connected to the lugs 431 of each snap plate 430. Anti-slip grooves are also provided on opposing sides of the snap plates 430. One end of the lock buckle 410 passes through the beginning or end of the chain 350 and is movably connected to the connecting piece 420 via bolts. Specifically, the lock buckle 410 is shaped like an inverted "U." To tighten the tail rope, the tail rope is placed on the clamping area 434 and then bolted through multiple rows of clamping holes 433 on the pair of snap plates 430. This allows the pair of snap plates 430 to clamp the tail rope. The anti-slip grooves on the snap plates 430 increase the friction between the tail rope and the pair of snap plates 430. The coordination between the retractable device 300 and the tail rope buckle 400 allows for the installation and use of a hand chain hoist, achieving faster lifting speeds, improving work efficiency, and reducing labor intensity.

[0042] Referring to Figure 1 , in one embodiment of the present invention, a pair of sunken platforms 500 facilitate the removal and installation of the tail rope and tail rope clip 400, significantly improving the efficiency of replacing the lifting container. The pair of sunken platforms 500 are located on either side of the pair of retracting and unfolding devices 300. The sunken platforms 500 include a ladder 510 and a platform 520, which is fixedly mounted at the bottom of the ladder 510. The sunken platforms 500 extend below the entrance of the vertical shaft, allowing workers to descend onto the platform 520 using the ladder 510 to perform work.

[0043] Please refer to 1 to Figure 5As shown, in one embodiment of the present invention, the lifting container 700 is replaced during construction. The lifting container 700 includes a lifting container body 710, a head rope 720, and a tail rope 730. The head rope 720 is located at the top of the lifting container body 710, and the tail rope 730 is located at the bottom of the lifting container body 710. The head rope 720 and the tail rope 730 are connected to the lifting container body 710 via a pin 740. The lifting container 700 also includes its own hydraulic lifting device (not shown in the figure). The hydraulic lifting device is located above the lifting container body 710 and is connected to the hydraulic lifting device via a pin 740 via the head rope 720. The lifting container body 710 can be raised and lowered by the hydraulic lifting device. In this embodiment, the lifting container 700 can be a vertical shaft lifting container such as a cage or a skip. In the prior art, the number of head ropes 720 is generally four, and the number of tail ropes 730 is generally two, so the number of retracting and releasing devices 300 and tail rope buckles 400 is also two correspondingly.

[0044] See also Figure 6 As shown, in one embodiment of the present invention, the vertical shaft hoisting container replacement device is applied. The present invention also provides a replacement method for the vertical shaft hoisting container replacement device, comprising:

[0045] S110, installing the beam frame at the wellhead of the vertical shaft, and lifting the old lifting container body to the wellhead and above the top surface of the flatbed transport vehicle through the hydraulic lifting device of the lifting container itself.

[0046] See also Figures 1 to 6 As shown, in one embodiment of the present invention, when placing the beam frame 100, one end of the beam frame 100 should be extended a distance above the wellhead position to facilitate the replacement of the old and new lifting container bodies 710. The lifting container body 710 is lifted to the wellhead and is 5 to 20 cm higher than the top surface of the flatbed transport vehicle 200.

[0047] S120, the tail rope is clamped by the tail rope buckle, and the output end of the oil cylinder extends, driving the head end and the tail end of the chain to simultaneously lift upward to suspend the tail rope, thereby loosening the tail rope.

[0048] S130, the flatbed transport vehicle moves to the wellhead, and the hydraulic lifting device sinks the old lifting container body and drops it onto the flatbed transport vehicle.

[0049] S140, loosen the head rope and the old lifting container body, and install a hand winch, connect the hand winch to the head rope and tighten it, remove the connection between the head rope and the old lifting container body; remove the connection between the tail rope and the old lifting container body, and complete the separation of the head rope and the tail rope from the old lifting container body.

[0050] S210, start the flatbed transport vehicle to transport out the old lifting container body, replace it with a new lifting container body, and then move it to the wellhead again by the flatbed transport vehicle.

[0051] S220, moving the head rope to the new lifting container body through the hand hoist and connecting it to the new lifting container body.

[0052] S230, the output end of the oil cylinder extends, and the tail rope is lifted and moved to the bottom of the new lifting container body and connected to the new lifting container body.

[0053] S240, check the reliability of the connection between the head rope and the tail rope and the new lifting container body, then retract the oil cylinder, lower the tail rope and return it to its original position, remove the tail rope buckle, drive the flatbed transport vehicle away from the wellhead, and complete the replacement.

[0054] Please refer to 7 to Figure 9 As shown, in another embodiment of the present invention, unlike the previous embodiment, the snap plate 430 in this embodiment is further provided with a sliding bevel 435, a sliding block 436, a buffer 437, and a shallow mounting groove 438. This allows the pair of snap plates 430 to be closer together and clamped when there is downward tension on the tail rope, effectively preventing it from falling off and ensuring stable clamping. The sliding bevel 435 is located within the tightening area 434, and one end of the buffer 437 is fixed to the bottom of the sliding bevel 435. One end of the sliding block 436 engages within the sliding bevel 435, and the other end is fixedly connected to the back of the shallow mounting groove 438. The shallow mounting groove 438 is also provided with the aforementioned anti-slip groove. The shallow mounting groove 438 regulates the shape of the tail rope, ensuring that it is in a vertical position within the shallow mounting groove 438. The sliding block 436 is T-shaped. The buffer 437 is, for example, a spring. To tighten the tail rope, the tail rope is placed in the shallow mounting groove 438, the pair of snap plates 430 are aligned, and then multiple bolts are passed through the two rows of clamping holes 433 to clamp the pair of snap plates 430. If the tail rope slips, the friction between the tail rope and the shallow mounting groove 438 will cause the sliding of the tail rope to move the shallow mounting groove 438 downward. As the sliding block 436 slides downward in the sliding bevel 435, the longitudinal groove of the sliding bevel 435 is tilted, causing the sliding block 436 to move the pair of shallow mounting grooves 438 closer together for clamping.
