Description

Technical Field

[0001] The present invention relates to a wire rope replacement equipment for a mine hoisting system, specifically an equipment applicable to cutting or replacing the hoisting wire rope of a Blair hoist, belonging to the technical field of mine equipment maintenance. Background Technique

[0002] A mine hoist refers to the main transportation equipment connecting the underground and the ground in mining engineering. The mine hoist is installed on the ground and is a hoisting machine that drives the hoisting container to run along the shaft or ramp with the help of a wire rope, and is widely used in vertical shafts and inclined shafts to hoist coal, ore, gangue, as well as lift personnel, lower materials, tools and equipment, etc. With the consumption of shallow mineral resources, deep mining is inevitable in mine exploitation. Currently, the commonly used mine hoists mainly include a friction hoist that relies on the friction between the wire rope and the drum for hoisting and a winding hoist that relies on wire rope winding for hoisting.

[0003] The drum of the friction hoist is driven by an electric motor, and uses the liner installed on the drum to provide friction to drive the wire rope to move, thereby pulling the hoisting container up and down. Since the friction hoist needs to use a balance tail rope to reduce the tension difference between the hoisting side and the lowering side wire ropes, the load on the cross-section of the wire rope will vary with the position of the container. That is, when the container reaches the wellhead, the weight of all the tail ropes is added to the connection part of the wire rope, and the stress reaches the maximum at this time. When the container reaches the bottom of the deep well, only the weight of the container is loaded on the connection part of the wire rope, and the stress reaches the minimum at this time. Therefore, under the same hoisting capacity, the greater the hoisting height, the greater the stress fluctuation value of the wire rope in the friction hoist. With the increase of the mining depth, it is necessary to meet the selection requirements of the friction hoist by reducing the hoisting capacity and reducing the effective load. That is to say, with the increase of the well depth, the effective load hoisted by the friction hoist becomes smaller and smaller, and the wire rope life and the reliability of the hoisting system will also become lower and lower. Research shows that when the hoisting depth is greater than 1000m, the hoisting capacity of the friction hoist drops rapidly. For every 100m increase in the well depth, the hoisting capacity decreases by about 14%. When the well depth reaches 1800m, its hoisting capacity tends to zero. Therefore, when the depth exceeds 1200m, it is not recommended to use a friction hoist, and generally a winding hoist is adopted.

[0004] The winding hoist does not have a tail rope balance and requires a motor with a relatively large power. Therefore, the equipment volume and weight are larger than those of the multi-rope friction hoist. The winding hoist includes a single-rope winding hoist and a multi-rope winding hoist. For a single-rope winding hoist that uses a single hoisting steel wire rope to connect with the hoisting container, as the well depth increases, to achieve hoisting in a 1000-meter deep well, the diameter of the hoisting steel wire rope will increase sharply, which not only causes difficulties in manufacturing the steel wire rope, but also makes it difficult for the steel wire rope to be wound smoothly due to the increase in its own weight and the decrease in flexibility. At the same time, to control the bending stress level of the steel wire rope, the diameter of the drum is usually above 8m, and the manufacturing and operation costs will increase exponentially. Therefore, it does not have engineering practicability. For a multi-rope winding hoist (i.e., Blair hoist) that uses two or more hoisting steel wire ropes to connect with the same hoisting container, its two or more hoisting steel wire ropes are respectively wound on a separated drum and are wound in multiple layers within each separated section. Since two or more hoisting steel wire ropes are used to jointly bear the large load, the diameter of each hoisting steel wire rope can be reduced under the condition of meeting safety requirements, and there is no need to solve the problem of the hoisting steel wire rope winding on the drum under heavy load operation conditions by increasing the diameter of the drum. Therefore, the multi-rope winding hoist is currently mainly used as a hoist for ultra-deep mines to carry out ultra-deep mine hoisting operations. For example, the hoisting operations in ultra-deep gold mines in South Africa all use multi-rope winding hoists, and most of them are double-rope winding hoists that use two hoisting steel wire ropes of the same type and opposite winding directions to offset the torque generated by the torsion of the hoisting steel wire rope for simultaneous winding and hoisting.

[0005] The challenges of ultra-deep well hoists come from the significant increase in the steel wire rope. In addition to the increased manufacturing difficulty, on the one hand, the increase in the length of the steel wire rope is more likely to cause vibration, especially when the hoist is running at high speed. This will lead to an increase in the amplitude and frequency of the dynamic load of the steel wire rope, thereby exacerbating the fatigue damage of the steel wire rope and resulting in an increase in the maintenance and replacement costs. This is mainly reflected in that the double-rope winding mine hoist is easily affected by unbalanced factors during processing, manufacturing, and operation, which can stimulate its detuning characteristics. Especially under the condition of high-speed movement, detuning vibration is likely to occur between the steel wire ropes, resulting in an increase in the tension difference between the steel wire ropes. When the hoist is operating under large load conditions, the tension imbalance phenomenon will cause excessive stress on a single steel wire rope, and in extreme cases, it may lead to the fracture of the steel wire rope and cause a safety accident. On the other hand, during the winding transition process of the steel wire ropes of the multi-rope winding hoist, the transition between layers and coils will cause phenomena such as vibration, impact, extrusion, and friction wear of the steel wire ropes. At the same time, the steel wire ropes themselves are also affected by bending, tension, torsion, and overload during the winding process. Therefore, for the multi-rope winding hoist applied to ultra-deep well hoisting, the selection, regular inspection, and maintenance of its hoisting steel wire ropes are more important than those of the multi-rope friction hoist.

[0006] For the lifting wire rope of the multi-rope winding hoist, fatigue wire breakage or corrosion at the head end connected to the drum and the tail end connected to the lifting container are extremely harmful. Therefore, cutting rope samples at the head and end of the lifting wire rope for the whole rope breaking tensile test is an important item for the regular inspection of the lifting wire rope of the multi-rope winding hoist. On the one hand, for new ropes that have not been used, it is required that the cutting part of the new rope sample is preferably cut at 5m away from the rope end to eliminate the negative impact of abnormal factors such as wire docking, unloading, and transportation on the test results during the manufacturing process; on the other hand, during the service period of the lifting wire rope, it often undergoes multiple regular inspections. This results in the lifting wire rope capacity of the multi-rope winding hoist being large enough to meet the ultra-deep mine hoisting operations and regular inspections of the lifting wire rope. Taking the ultra-deep gold mine in South Africa as an example, the length of the lifting wire rope used in the multi-rope winding hoist is usually a surplus of 1 / 3 of the depth of the well. Due to the harsh working environment underground in ultra-deep mines, with high temperature, humidity and ground pressure, it is not only extremely difficult to complete the work of cutting the rope sample of the hoisting wire rope underground, but also the operation procedure is complicated. Therefore, the work of cutting the rope sample of the hoisting wire rope is usually completed above ground, which requires that the hoisting container be completely lifted to the wellhead and positioned, and then the connection between the hoisting wire rope and the hoisting container be released. Then, the rotation of the drum is controlled to release the entire hoisting wire rope and the connection between the hoisting wire rope and the drum is released before cutting the rope sample samples at both ends of the hoisting wire rope. On the one hand, since the lifting wire rope of the multi-rope winding hoist has a large rope capacity and the lifting wire rope of the multi-rope winding hoist is usually a wire rope with high tensile strength, good anti-rotation performance and anti-fatigue performance, the lifting wire rope fully released from the drum is not only long but also difficult to coil. Taking the ultra-deep gold mine in South Africa as an example, the lifting wire rope released from the drum is usually coiled over a large area and laid flat on the ground with the help of a tower crane, which usually takes up a huge space; on the other hand, after the rope is cut and tested to be qualified, it is difficult to apply the pre-tightening force of the lifting wire rope when reconnecting it to the drum and winding it. Summary of the invention

An outer cover 2.4 including a wire guiding hole 2.5 can be arranged outside the clamping and conveying frame 2.2, and the wire guiding hole 2.5 corresponds to the wire guiding roller group 1.4; As Figure 9As shown in the figure, the clamping and conveying unit 2.1 includes two sets of chain-type wire rope clamping and conveying mechanisms arranged in parallel and spaced apart vertically, and a clamping distance control mechanism arranged between the two sets of chain-type wire rope clamping and conveying mechanisms.

A clamping carrier cooperating with the wire rope is also provided on the link of the conveying chain. The space between the upper and lower adjacent conveying chains of the two sets of chain-type wire rope clamping and conveying mechanisms forms a wire rope clamping and conveying space. After the wire rope is fed into the wire rope clamping and conveying space, by controlling the action of the clamping distance control mechanism, the distance between the two sets of chain-type wire rope clamping and conveying mechanisms can be controlled to be reduced, that is, the clamping carriers of the conveying chains of the two sets of chain-type wire rope clamping and conveying mechanisms can be in a state of clamping the wire rope. By controlling the synchronous rolling of the conveying chains of the two sets of chain-type wire rope clamping and conveying mechanisms, the wire rope can be clamped and conveyed by the frictional force of the clamping carrier on the wire rope. The clamping and conveying unit 2.1 is a prior art (Patent No.: CN109867161A, Patent Name: A Linear Clamping Mechanism of a Wire Rope Conveying Device), and will not be described in detail here.

When the wire rope winding winch 3.2 is arranged at the left and / or right side of the frame 1, a rear redirecting rope guide device 5 is required to be arranged at the rear of the wire rope conveying force and speed matching part 2. The wire rope winding winch 3.2 includes a drum support frame for supporting the wire rope drum 8. The drum support frame includes a drum main support frame 3.2.1 and a drum sub-support frame 3.2.2 installed and connected to the drum main support frame 3.2.1.

After the wire rope drum 8 is coaxially fixedly installed on the winch main shaft 3.2.3, the winch main shaft 3.2.3 can drive the wire rope drum 8 to rotate by controlling the action of the winch main shaft drive component to realize the winding and storage of the lifting wire rope, and the rotation speed of the winch main shaft 3.2.3 matches the clamping and conveying speed of the clamping and conveying unit 2.1. The speed matching can be achieved by using a method in which the winch main shaft drive component and the sprocket drive component 2.3 share the same drive component and control the transmission ratio of the winch main shaft 3.2.3 through a transmission connection, or by using a method in which the winch main shaft drive component and the sprocket drive component 2.3 respectively match the rotation speed of the winch main shaft 3.2.3 and the rotation speed of the driving sprocket.

[0050] The rope arranging device 6 is used to arrange the lifting wire rope 9 wound on the wire rope drum 8 to avoid tangled ropes. The rope arranging device 6 can be installed on the wire rope winding winch 3.2 or the frame 1. The rope arranging device 6 is a prior art and will not be described in detail here.

When the rope winding winch 3.2 is arranged on the left or right side of the frame 1), and the rope-winding speed of the rope-winding device 6 matches the rotation speed of the winch main shaft 3.2.3, the speed matching can be achieved by connecting the rope-winding device 6 to the winch main shaft 3.2.3 through transmission and controlling the rope-winding speed of the rope-winding device 6 by controlling the transmission ratio, or by separately setting a driving component for the rope-winding device 6 and controlling the rotation speed of the driving component of the rope-winding device 6 to match the rotation speed of the winch main shaft 3.2.3.

[0051] The centralized electro-hydraulic control device 7 is used to control the traveling action of the traveling chassis 1.1, the clamping and conveying action of the clamping and conveying unit 2.1, and the winding action of the wire rope winding winch 3.2.

[0052] When using the Ben Blair hoist to cut and replace the hoisting wire rope of the Blair hoist and performing the cutting operation on the hoisting wire rope of the Blair hoist to obtain rope samples at the head and tail ends of the hoisting wire rope, after removing the hoisting container, send the rope end of the 9-strand hoisting wire rope of the Blair hoist into the wire rope clamping and conveying space of the wire rope conveying force and speed matching part 2, and through the centralized electro-hydraulic control device 7, control the conveying chains of the two groups of chain-type wire rope clamping and conveying mechanisms to synchronously match the rope releasing speed of the Blair hoist drum for rolling in opposite directions. Then, by coordinating the actions of the wire rope winding part 3 and the rope arranging device 6, the hoisting wire rope 9 released from the Blair hoist drum can be clamped and conveyed and wound on the wire rope reel 8, so that the hoisting wire rope 9 occupies a smaller space. After the hoisting wire rope 9 is wound to the set length, stop winding. The wire rope conveying force and speed matching part 2 can provide a locking force to the hoisting wire rope 9 to prevent the wire rope from slipping. Then, the hoisting wire rope 9 can be cut off behind the wire rope conveying force and speed matching part 2, and the rope sample at the head end of the hoisting wire rope 9 wound on the wire rope reel 8 can be taken. After reconnecting the rope end of the hoisting wire rope 9 after taking the rope sample at the head end to the wire rope reel 8, wind it again. After the remaining hoisting wire rope 9 is all wound on the wire rope reel 8, the rope sample at the tail end of the hoisting wire rope 9 can be cut according to the required length dimension. After cutting the rope sample at the tail end, through the wire rope conveying force and speed matching part 2 and the wire rope winding part 3, perform reverse clamping and conveying, release the rope end of the hoisting wire rope 9 after completing the cutting of the rope sample, and reconnect it to the Blair hoist drum. Then, when starting the Blair hoist, through the centralized electro-hydraulic control device 7, control the wire rope conveying force and speed matching part 2 and the wire rope winding part 3 to perform reverse clamping and conveying, and control the speed of the reverse clamping and conveying to be passively matched with the hoisting speed of the Blair hoist. By the constant resistance clamping and conveying of the wire rope conveying force and speed matching part 2, a pre-tightening force can be applied to the hoisting wire rope 9 rewound on the Blair hoist drum.When replacing the hoisting wire rope of the Blair hoist, during the rope replacement operation, the old hoisting wire rope released from the Blair hoist drum can be clamped and conveyed and wound on the wire rope reel 8 through the coordinated actions of the wire rope conveying force and speed matching part 2, the wire rope winding part 3, and the rope arranging device 6. After all the old hoisting wire ropes are wound on the wire rope reel 8, the wire rope reel 8 wound with the old hoisting wire rope is removed from the main shaft 3.2.3 of the winch and a wire rope reel 8 wound with a new hoisting wire rope is installed. Through the reverse clamping and conveying of the wire rope conveying force and speed matching part 2 and the wire rope winding part 3, the end of the new hoisting wire rope is released and connected to the Blair hoist drum. Then, while starting the Blair hoist, the wire rope conveying force and speed matching part 2 and the wire rope winding part 3 are controlled by the centralized electro-hydraulic control device 7 to perform reverse clamping and conveying, and the speed of the reverse clamping and conveying is passively matched with the hoisting speed of the Blair hoist. Thus, a pre-tightening force can be applied to the new hoisting wire rope wound on the Blair hoist drum through the constant resistance clamping and conveying of the wire rope conveying force and speed matching part 2.

[0053] For a double-rope winding Blair hoist, to simultaneously perform the rope winding and unwinding operations on the two wire ropes of the double-rope winding Blair hoist, as a further improvement of the present invention, the clamping and conveying units 2.1 of the wire rope conveying force and speed matching part 2 are symmetrically arranged in two groups on the left and right. The wire rope winding winches 3.2 of the wire rope winding part 3 are correspondingly arranged in two groups, and the two groups of wire rope winding winches 3.2 are symmetrically arranged on the left and right sides of the frame 1. The front wire guiding device 4 and the rear wire guiding device 5 are both symmetrically arranged in two groups corresponding to the clamping and conveying units 2.1 on the left and right. The rope arranging device 6 is symmetrically arranged in two groups corresponding to the two groups of wire rope winding winches 3.2 on the left and right.

[0054] For the convenience of storage and transfer, as a further improvement of the present invention, the two groups of wire rope winding winches 3.2 symmetrically arranged on the left and right sides of the frame 1 adopt a telescopic and rotary storage and deployment method, that is, as Figure 10As shown, the wire rope winding part 3 includes a slewing frame 3.1 installed on the frame 1 through a slewing bearing 1.3, and the slewing center axis of the slewing frame 3.1 is located in the middle vertical plane of the frame 1 along the left and right directions. In order to avoid interference between the slewing frame 3.1 and the clamping conveying frame 2.2 during the slewing process, the slewing frame 3.1 can be symmetrically arranged relative to the center of the clamping conveying frame 2.2. A main slewing frame slewing driving component is arranged on the slewing bearing mounting seat 3.1.1 at the bottom of the slewing frame 3.1 or on the frame 1. The main slewing frame slewing driving component can be an electric motor structure or a hydraulic motor structure, preferably a hydraulic motor structure. By controlling the main slewing frame The action of the slewing drive component can realize the slewing action of controlling the slewing frame 3.1 to slew along the vertical slewing axis; the two sets of wire rope winding winches 3.2 are arranged symmetrically with respect to the slewing frame 3.1, the main drum support frame 3.2.1 is installed and connected to the slewing frame 3.1, the auxiliary drum support frame 3.2.2 is located on the outer side of the main drum support frame 3.2.1, the winch main shaft 3.2.3 is detachably installed between the main drum support frame 3.2.1 and the auxiliary drum support frame 3.2.2, the bottom of the auxiliary drum support frame 3.2.2 is provided with a bottom crossbeam extending inwardly, the bottom of the main drum support frame 3.2.1 A crossbeam guide sleeve is provided which cooperates with the bottom crossbeam and is sleeved and installed on the bottom crossbeam. A bottom crossbeam accommodating frame 3.1.6 is provided in the left-right direction at a position corresponding to the bottom crossbeam on the slewing frame 3.1, and a bottom crossbeam telescopic driving mechanism 3.1.4 is provided in the bottom crossbeam accommodating frame 3.1.6. The bottom crossbeam can be extended into the bottom crossbeam accommodating frame 3.1.6 and is transmission-connected with the bottom crossbeam telescopic driving mechanism 3.1.4. The bottom crossbeam telescopic driving mechanism 3.1.4 includes a bottom crossbeam telescopic driving component. The bottom crossbeam telescopic driving component can be a rotary driving structure such as an electric motor or a hydraulic motor, or can be a telescopic cylinder driving a linear reciprocating motion. The transmission connection between the telescopic drive mechanism 3.1.4 of the bottom crossbeam and the bottom crossbeam can be a gear rack transmission, a telescopic cylinder transmission, or a chain transmission or other transmission methods that can realize linear reciprocating motion. By controlling the telescopic drive component of the bottom crossbeam to drive the movement of the bottom crossbeam, the auxiliary support frame 3.2.2 of the drum can be controlled to move outward away from the main support frame 3.2.1 of the drum, or to move inward and abut against the outer end of the main support frame 3.2.1 of the drum. The rope guide 6 can be removably installed between the main support frame 3.2.1 of the drum and the auxiliary support frame 3.2.2. When transfer operations are required, first remove the winch main shaft 3.2.3 and the rope guide 6, and then Figure 11 As shown, the bottom cross beam telescopic driving component is controlled to move so that the left and right reel auxiliary support frames 3.2.2 are moved inward and respectively abut against the outer ends of the left and right reel main support frames 3.2.1. At this time, the bottom cross beams of the reel auxiliary support frames 3.2.2 are completely retracted into the bottom cross beam accommodating frame 3.1.6, and then as shown in FIG. Figure 3As shown, control the rotation drive component of the main slewing frame to rotate the slewing frame 3.1 by 90°. At this time, the main drum support frame 3.2.1 and the auxiliary drum support frame 3.2.2 that are abutted against each other in the left-right direction will rotate and retract into the frame 1 in the front-back direction, realizing the storage of the two sets of wire rope winding winches 3.2. When the operation needs to be unfolded, the unfolding process is the reverse process of the storage process. First, control the rotation drive component of the main slewing frame to rotate the slewing frame 3.1 by 90°, then control the telescopic drive component of the bottom cross beam to move both the left and right auxiliary drum support frames 3.2.2 outward by a set distance away from the main drum support frame 3.2.1. Finally, the winch spindle 3.2.3 with the wire rope drum 8 fixedly installed coaxially and the rope arranging device 6 can be erected and installed between the main drum support frame 3.2.1 and the auxiliary drum support frame 3.2.2.

[0055] When cutting or replacing the lifting wire rope 9 of the Blair hoist, in order to achieve a more stable wire rope winding effect, as a further improvement scheme of the present invention, the wire rope winding winch 3.2 adopts a liftable floor-standing structure, that is, the wire rope winding part 3 further includes a guiding and lifting mechanism, such as Figure 10 , Figure 11As shown in the figure, the guiding and lifting mechanism includes a winch lifting guiding inner frame 3.2.4 fixedly installed and connected to the main drum support frame 3.2.1. An outer winch lifting guiding frame 3.1.2 is sleeved and installed externally on the vertically arranged winch lifting guiding inner frame 3.2.4. To ensure the guiding and lifting effect, a guiding structure such as a guide rail or a guide wheel can be provided between the winch lifting guiding inner frame 3.2.4 and the winch lifting guiding outer frame 3.1.2. A winch lifting driving component 3.1.5 is also provided between the winch lifting guiding inner frame 3.2.4 and the winch lifting guiding outer frame 3.1.2, which is respectively installed and connected to the winch lifting guiding inner frame 3.2.4 and the winch lifting guiding outer frame 3.1.2. The winch lifting driving component 3.1.5 can be a telescopic cylinder structure, or other structures such as a screw and nut structure that can achieve linear reciprocating motion, preferably a hydraulic cylinder structure. By controlling the action of the winch lifting driving component 3.1.5, the lifting of the main drum support frame 3.2.1 driving the wire rope winding winch 3.2 as a whole can be achieved. During the operation state, the winch lifting driving component 3.1.5 can be controlled to make the wire rope winding winch 3.2 lower to the ground. At this time, the wire rope winding winch 3.2 can be further positioned through the ground anchor bolts. During the transfer state, the winch lifting driving component 3.1.5 can be controlled to make the wire rope winding winch 3.2 rise off the ground, and at this time, it does not affect the transfer and movement of the entire equipment. When the two groups of wire rope winding winches 3.2 symmetrically arranged on the left and right sides of the frame 1 adopt the telescopic and rotating storage and deployment method, the winch lifting guiding outer frame 3.1.2 is fixedly installed and connected to the rotating frame 3.1 (that is, the main drum support frame 3.2.1 is installed and connected to the rotating frame 3.1 through the guiding and lifting mechanism). A clutch connection structure is also provided between the inner end of the bottom cross beam of the auxiliary drum support frame 3.2.2 and the bottom cross beam telescopic driving mechanism 3.1.4. Taking the chain drive method as the transmission connection method between the bottom cross beam telescopic driving mechanism 3.1.4 and the bottom cross beam as an example, the clutch connection structure can be a connection pin arranged on the transmission chain and a bayonet structure with an upward opening and arranged on the bottom cross beam in cooperation. When the wire rope winding winch 3.2 is controlled to rise to the set height, the bayonet structure on the bottom cross beam can be clamped on the connection pin on the transmission chain, and the telescopic action of the bottom cross beam can be realized by driving the bayonet structure through the connection pin by chain drive. Taking the telescopic cylinder drive method as the transmission connection method between the bottom cross beam telescopic driving mechanism 3.1.4 and the bottom cross beam as an example, the clutch connection structure can be a buckle structure arranged on the telescopic end of the telescopic cylinder and extending downward and a slot structure with an upward opening and arranged on the bottom cross beam in cooperation. When the wire rope winding winch 3.2 is controlled to rise to the set height, the slot structure on the bottom cross beam can be clamped on the buckle structure on the telescopic end of the telescopic cylinder, and the telescopic action of the bottom cross beam can be realized by driving the slot structure through the buckle structure by the telescopic action of the telescopic cylinder.

[0056] For the convenience of the forward guiding rope device 4 to be stored and transferred, as a further improvement scheme of the present invention, as Figure 12 shown, the forward guiding rope device 4 includes a swing guiding frame 4.1 and a guiding wheel disc 4.2. The guiding wheel disc 4.2 with a circular or fan-shaped structure is positioned and installed at the front end of the swing guiding frame 4.1 through a positioning pin shaft 4.4 arranged at its center position. A plurality of guiding rope wheels 4.5 evenly spaced along the circumferential direction of the guiding wheel disc 4.2 are installed in rolling fit at the arc edge position of the guiding wheel disc 4.2, and the central axis of the guiding rope wheel 4.5 is arranged in the horizontal direction. The rear end of the swing guiding frame 4.1 is installed on the front vertical frame 1.2 through a swing rotating shaft 4.3 with the central axis arranged in the vertical direction. The swing guiding frame 4.1 can swing relative to the front vertical frame 1.2 along the left-right direction along the central axis of the swing rotating shaft 4.3. A swing angle locking structure is also provided on the swing guiding frame 4.1 or the front vertical frame 1.2. When the central axis of the swing guiding frame 4.1 swings to be parallel to the central axis of the driving sprocket of the clamping and conveying unit 2.1, the swing angle locking structure can lock the swing angle, that is, as Figure 1 shown, when in the fully unfolded state, the swing guiding frame 4.1 swings forward and protrudes forward, as Figure 3 shown, when in the fully stored state, the swing guiding frame 4.1 swings backward and is in a state of leaning against the side of the front vertical frame 1.2. The swing angle locking structure can lock the swing angle in both the fully unfolded state and the fully stored state. To achieve automatic unfolding or storage, a swing control component can also be provided between the swing guiding frame 4.1 and the front vertical frame 1.2. The swing control component can be a telescopic cylinder structure, or other structures such as a motor or a hydraulic motor structure.

[0057] The rear guiding rope device 5 can be a guiding rope structure including a circular or fan-shaped structure wheel disc, or a multi-segment connecting rod type guiding rope structure including the guiding rope wheel 4.5. When the two groups of wire rope winding winches 3.2 are symmetrically arranged on the left and right sides of the frame 1 as described above, since the rear guiding rope device 5 needs to deflect the lifting wire rope 9 output from the rear end of the clamping and conveying unit 2.1 backward to the left and right directions and forward, and the width dimension of deflecting to the left and right directions should match the width dimension of the wire rope winding winch 3.2 to facilitate the winding of the lifting wire rope 9 on the wire rope drum 8. Therefore, when the rear guiding rope device 5 adopts a guiding rope structure including a circular or fan-shaped structure wheel disc, the dimension of the circular or fan-shaped structure wheel disc along the left and right directions is relatively large and it is not convenient for storage. When the rear guiding rope device 5 adopts a multi-segment connecting rod type guiding rope structure, it can be deformed and stored by disassembling the connecting rod. Therefore, to achieve the convenience of the rear guiding rope device 5 for storage and transfer, as a preferred scheme of the present invention, the rear guiding rope device 5 is a multi-segment connecting rod type guiding rope structure including the guiding rope wheel 4.5, that is, as Figure 13 、 Figure 14As shown in the figure, the later modified guide rope device 5 includes an arc-shaped guide rope wheel frame 5.4, a first connecting rod 5.5, a second connecting rod 5.6, and a third connecting rod 5.7. The front end of the first connecting rod 5.5 is fixedly arranged behind the steel wire rope conveying force and speed matching part 2. A plurality of modified guide rope wheels 4.5 are installed in rolling fit at the arc edge position of the arc-shaped guide rope wheel frame 5.4 and are evenly spaced along the arc direction. The central axis of the modified guide rope wheel 4.5 is arranged vertically. The arc-shaped guide rope wheel frame 5.4 is provided in two pieces. One end of each of the two arc-shaped guide rope wheel frames 5.4 is respectively hinged and installed to the rear end of the first connecting rod 5.5 and one end of the second connecting rod 5.6 through a hinge pin with a vertically arranged central axis. The other ends of the two arc-shaped guide rope wheel frames 5.4 are respectively hinged and installed to the other end of the second connecting rod 5.6 and one end of the third connecting rod 5.7 through a hinge pin with a vertically arranged central axis. The other end of the third connecting rod 5.7 is hinged and installed to the rod body of the first connecting rod 5.5 through a hinge pin with a vertically arranged central axis. The arc-shaped guide rope wheel frame 5.4, the first connecting rod 5.5, the second connecting rod 5.6, and the third connecting rod 5.7 jointly form a five-link structure that can deflect the lifting steel wire rope 9 by 180°. When in the fully retracted state, the third connecting rod 5.7 can be removed, and then the second connecting rod 5.6 and the arc-shaped guide rope wheel frame 5.4 can be folded and retracted to the side of the first connecting rod 5.5. When in the fully deployed state, installing and connecting the third connecting rod 5.7 can form a five-link structure. The balanced pressure exerted on the arc-shaped guide rope wheel frame 5.4 and the second connecting rod 5.6 after the lifting steel wire rope 9 is deflected by 180° through the two arc-shaped guide rope wheel frames 5.4 can cause the support self-locking of the five-link structure and prevent deformation, thereby realizing the stable deflection of the lifting steel wire rope 9.

[0058] When the lifting steel wire rope 9 enters the steel wire rope drum 8 and winds around the steel wire rope drum 8, in order to minimize the torsion of the lifting steel wire rope 9, it is necessary to appropriately extend the length of the first connecting rod 5.5 so that the incident angle of the lifting steel wire rope 9 entering the steel wire rope drum 8 is as small as possible. However, a longer length of the first connecting rod 5.5 will increase the length of the entire equipment, and thus increase the turning radius of the entire equipment during walking, making it inconvenient for transfer operations. Therefore, as a further improvement scheme of the present invention, as Figure 13 、 Figure 14As shown, the front end of the first connecting rod 5.5 is fixedly arranged behind the wire rope conveying force and speed matching part 2 through a telescopic assembly. The telescopic assembly includes a guide cylinder 5.1, a telescopic cylinder 5.2 and a telescopic cylinder 5.3. The telescopic cylinder 5.2 is coaxially and slidably installed in the guide cylinder 5.1. The cylinder body end of the telescopic cylinder 5.3 arranged inside the telescopic cylinder 5.2 is fixedly installed and connected with the guide cylinder 5.1, and the telescopic end is fixedly installed and connected with the telescopic cylinder 5.2. The telescopic cylinder 5.3 is preferably a hydraulic cylinder. The front end of the guide cylinder 5.1 is positioned. The rear end of the telescopic cylinder 5.2 is fixedly installed and connected with the front end of the first connecting rod 5.5. By controlling the telescopic action of the telescopic cylinder 5.3, the change of the length dimension of the rear guide rope device 5 in the front and rear directions can be realized. When in the working state, the telescopic cylinder 5.3 can be controlled to fully extend to minimize the torsion of the hoisting wire rope 9. When in the transfer state, the telescopic cylinder 5.3 can be controlled to fully retract to shorten the length dimension of the whole equipment.

[0059] The hoisting wire rope cutting and replacing equipment of the present Blair hoist can realize that the hoisting wire rope 9 discharged from the Blair hoist occupies a small space, and at the same time, it is convenient to intercept the rope sample at the head and tail ends of the hoisting wire rope. The pre-tightening force can be applied to the hoisting wire rope 9 rewound on the drum of the Blair hoist through the constant resistance clamping and conveying of the wire rope conveying force and speed matching part 2. The operation of winding and unwinding the two wire ropes of the double-rope winding Blair hoist can be realized simultaneously, with high working efficiency and safety, and is particularly suitable for the cutting or replacing operation of the hoisting wire rope of the Blair hoist used for hoisting operations in ultra-deep mines as an ultra-deep mine hoist.
