[0002] Replacing the hoisting container of the shaft hoist has always been a major problem in the maintenance of the shaft in the mining industry. When replacing the hoisting container, the hoisting container is currently lifted directly by a crane for replacement. This operation method has great safety hazards, and the maintenance time is long, the maintenance efficiency is low, the labor intensity of the operators is high, and it affects production operations. In addition, when replacing the tail rope, the weight of the tail rope is all borne by the hand chain hoist, which further increases the labor intensity of the operators.

[0003] The prior art patent application number is CN108516450A, which is a method for quickly replacing a large skip in a coal mine. When replacing the old skip with the new one, a lifting device is used to lift the old skip to assist in completing the replacement of the skip. In the prior art, the skip is lifted by a lifting device, and the skip is easy to shake during the lifting process, which poses a safety hazard. Summary of the invention

[0004] The technical problem to be solved by the present invention is to solve the problem of potential safety hazards when replacing an old lifting container with a new one by using a lifting device.

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

[0009] 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;

[0010] Loosen the head rope and the old lifting container body, install a hand chain hoist, connect the hand chain hoist 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;

[0011] The flatbed transport vehicle is started to transport out the old lifting container body, and after replacing the new lifting container body, the new lifting container body is moved to the wellhead by the flatbed transport vehicle again;

[0040] Please refer to 1 to Figure 4As shown, in one embodiment of the present invention, a pair of retractable devices 300 are respectively arranged in a pair of square tubes 110, and are mutually staggered in the horizontal direction. The retractable devices 300 are used to lift the tail rope, so that the contact and connection between the tail rope and the lifting container are safer and more convenient. The retractable device 300 includes a cylinder 310 and a push sprocket 320. The cylinder seat of the cylinder 310 is fixed in the square tube 110. The push sprocket 320 is arranged 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 in the square tube 110. The retractable device 300 also includes 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, and the second redirecting sprocket 340 is located at the top of the inner wall of the square tube 110. The first redirecting sprocket 330 and the second redirecting sprocket 340 are staggered in the horizontal direction. The head end of the chain 350 passes through the bottom of the square tube 110 and is located on the first redirecting sprocket 330, then turns to the push sprocket 320 through the first redirecting sprocket 330, then passes through the push sprocket 320 and is located on the second redirecting sprocket 340, and finally passes through the bottom of the square tube 110 and is flush with its end after being redirected by the second redirecting sprocket 340. The output end of the oil cylinder 310 extends, pushes the push sprocket 320, so that the head section and the end of the chain 350 rise synchronously, and the output end of the oil cylinder 310 contracts, driving the push sprocket 320 to contract and make the head section and the end of the chain 350 fall synchronously. In this embodiment, the chain 350 is a round link chain, and the single-end breaking load of the single-end chain 350 is 610~820KN, and the double-end total breaking load can reach 1200~1600KN. The sprocket material of the driving sprocket 320, the first redirecting sprocket 330 and the second redirecting sprocket 340 is chromium-molybdenum alloy, which has extremely high recoil and wear resistance after modulation treatment, and the sprocket bearings adopt high-strength needle bearings, which have large load-bearing capacity and flexible rotation. The retracting device 300 adopts a hydraulic chain retracting method, which can effectively and safely lift and lower the tail rope.

[0041] Please refer to 1 and Figure 4As shown, in one embodiment of the present invention, the tail rope buckle 400 is movably connected with the head end and the end of the chain 350 to fasten the tail rope. The tail rope buckle 400 includes a lock buckle 410, a connecting piece 420 and a snap plate 430. A pair of lock buckles 410 are respectively buckled with the head end and the end of the chain 350 and then respectively connected to one end of a pair of connecting pieces 420. Lugs 431 are provided on both sides of the top of the snap plate 430, and fixing holes 432 are provided on the lugs 431. The snap plate 430 is also longitudinally provided with two rows of clamping holes 433, and a clamping area 434 is provided between the two rows of clamping holes 433. The connecting piece 420 is located between the pair of snap plates 430, and the pair of connecting pieces 420 are respectively detachably connected to the lugs 431 of the pair of snap plates 430, and anti-slip grooves are also provided on the opposite sides of the pair of snap plates 430. One end of the lock 410 passes through the head or the end of the chain 350 and is movably connected to the connecting piece 420 through a bolt. Specifically, the lock 410 is in an inverted "U" shape. When tightening the tail rope, the tail rope is placed on the clamping area 434, and then multiple bolts are sequentially passed through the two columns and multiple rows of clamping holes 433 on a pair of snap plates 430, so that the pair of snap plates 430 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. Through the cooperation of the retracting device 300 and the tail rope buckle 400, the installation and use of the reference hand chain hoist can achieve fast lifting speed, improve work efficiency and reduce the labor intensity of the staff.

[0042] As shown in Figure 1, in one embodiment of the present invention, a pair of sunken platforms 500 can facilitate the workers to disassemble and assemble the tail rope and the tail rope buckle 400, which can greatly improve the work efficiency of replacing the lifting container. The pair of sunken platforms 500 are respectively located on one side of the pair of retracting devices 300. The sunken platform 500 includes an escalator 510 and a table 520, and the table 520 is fixedly installed at the bottom of the escalator 510. The sunken platform 500 can extend below the entrance of the vertical shaft, and the workers can use the escalator 510 to descend to the table 520 to perform operations.

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, and the head rope 720 and the tail rope 730 are connected to the lifting container body 710 through a pin 740. The lifting container 700 also includes a hydraulic lifting device (not shown in the figure) that comes with it. The hydraulic lifting device is located above the lifting container body 710, and the lifting container 700 and the hydraulic lifting device are connected through the head rope 720 through the pin 740. 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 and a bucket. In the prior art, the number of head ropes 720 is generally 4, and the number of tail ropes 730 is generally 2, so the number of retracting and releasing devices 300 and tail rope buckles 400 is also 2 correspondingly.

[0044] See also Figure 6 As shown, in one embodiment of the present invention, the vertical shaft lifting container replacement device is applied. The present invention also provides a replacement method for the vertical shaft lifting 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 is extended to a distance at 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 be lifted upward at the same time to suspend the tail rope, so that the tail rope is relaxed.

[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 to connect and tighten the hand winch to the head rope, and 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 the 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 winch and connecting it to the new lifting container body.

[0052] S230, the output end of the oil cylinder extends out, 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 Fig. 9 As shown, in another embodiment of the present invention, different from the previous embodiment, the snap plate 430 in this embodiment is also provided with a sliding bevel 435, a sliding block 436, a buffer 437 and a shallow installation groove 438, which can make a pair of snap plates 430 closer to each other for clamping when there is a downward pulling force on the tail rope, effectively preventing the falling off and clamping stably. The sliding bevel 435 is located in the tightening area 434, and one end of the buffer 437 is fixed at the bottom of the sliding bevel 435. One end of the sliding block 436 is engaged in the sliding bevel 435, and the other end is fixedly connected to the back of the shallow installation groove 438, and the shallow installation groove 438 is also provided with the anti-slip pattern. The shallow installation groove 438 can regularize the shape of the tail rope so that it is guaranteed to be in a vertical state in the shallow installation groove 438. Among them, the sliding block 436 is in a "T" shape. The buffer 437 is, for example, a spring. When tightening the tail rope, the tail rope is placed in the installation shallow groove 438, and after the pair of snap plates 430 are fitted, a plurality of bolts are passed through two rows of clamping holes 433 to clamp the pair of snap plates 430. When the tail rope has a downward pulling force, the sliding block 436 is driven to slide downward in the sliding inclined groove 435. Because the longitudinal groove of the sliding inclined groove 435 is inclined, the sliding block 436 pulls the pair of snap plates 430 closer to be clamped. When the tail rope slips, due to the friction between the tail rope and the installation shallow groove 438, when the tail rope slides, there will be a certain friction force to drive the installation shallow groove 438 to move downward. Since the sliding block 436 slides downward in the sliding inclined groove 435, and the longitudinal groove of the sliding inclined groove 435 is inclined, the sliding block 436 drives the pair of installation shallow grooves 438 closer to be clamped.
