Description

Technical Field

[0001] The invention relates to a winch wire rope winding method, in particular to a load-bearing winding method of a winch wire rope, and belongs to the technical field of shaft excavation construction equipment. Background Art

[0002] like Figure 1 The shown sinking shaft boring machine is a new type of shaft excavation equipment, which consists of a boring machine and multiple winches. The multiple winches synchronously lift and lower the boring machine; while the boring machine is lowered, it completes the loading of the cutter and the vertical feeding movement. The winch is an important part of the sinking shaft boring machine to complete the shaft excavation. Before construction, the wire rope of the winch needs to be wound around the drum with a certain pre-tightening force, so that when the winch is synchronously lowered, the speed and stroke of the wire rope can be fully measured and controlled; ensure that the boring machine can maintain a horizontal posture and lower steadily; the wire rope will not bite, stagger, or be tangled, and the excavation construction will be more stable. If the winch can wind the wire rope as required before leaving the factory, it can also shorten the equipment installation time and the total construction period.

[0003] In order to wind the wire rope from the finished wire rope drum with a certain pre-tension force onto the winch drum, it is usually necessary to configure a wire rope pre-tension winding device. The device must have the following functions: (1) It can receive the wire rope released from the finished wire rope drum and smoothly feed the rope to the winch drum; (2) It has a tension adjustment function and can continuously apply 5-10 tons of wire rope pre-tension; (3) It can evenly and orderly wind the wire rope onto the drum. However, if a new wire rope pre-tension winding device that meets the above functions is redesigned, it will not only be time-consuming, but also increase the equipment cost. Summary of the invention

[0004] In view of this, the present invention provides a method for winding a winch wire rope with load, which directly utilizes the winches of a sinking shaft boring machine, two by two in a group, which serve as winding winches and transition loading winches, and winds the wire rope onto the winch drum according to the set pre-tightening force, without the need for additional customized wire rope pre-tightening winding devices.

[0005] The technical solution of the present invention is: a method for winding a winch wire rope with load, wherein one winch is used as a target winch for winding the wire rope, and its corresponding drum is the target drum; another winch is used as a transition loading winch, and its corresponding drum is the transition drum;

[0006] The target winch is driven by a motor to rotate and wind a steel wire rope to a target drum; the steel wire rope is provided by a steel wire rope reel;

[0007] The transition drum is used as a transition loading drum of the steel wire rope for passive rotation; at the same time, the transition loading winch provides a pre-tightening force for the steel wire rope to realize loaded winding of the steel wire rope.

[0008] As a preferred embodiment of the present invention: directly using multiple groups of winches equipped with the equipment using the winch to realize the loaded winding of the steel wire rope of each winch;

[0009] The equipment is provided with N winches, where N is an integer greater than or equal to 2;

[0010] During winding, the Nth winch is used as a transition loading winch, and the first winch to the (N-1)th winch are used as target winches in sequence to complete the loaded winding of the wire rope;

[0011] When the wire rope is wound on the Nth winch, the wire rope is first wound onto the drum of the (N-1)th winch as a transition; then, with the Nth winch as the driving end, the wire rope on the drum of the (N-1)th winch as a transition is reversely wound onto the drum of the Nth winch; in this process, the (N-1)th winch serves as a passive loading end.

[0012] As a preferred embodiment of the present invention, during the loaded winding process of the wire rope, the preload force of the wire rope is adjusted by adjusting the number of windings of the wire rope on the transition drum or / and adjusting the clamping force of the transition loading winch's own brake.

[0013] As a preferred embodiment of the present invention: when the pre-tightening force is too large, the number of windings of the wire rope on the transition drum is reduced;

[0014] When the preload force is insufficient, first increase the number of turns of the wire rope on the transition drum; if the preload force still does not reach the required value after increasing to the set number of turns, use the brake loading of the transition loading winch to increase the preload force of the wire rope.

[0015] As a preferred embodiment of the present invention: the length of the wire rope provided by the wire rope reel is just enough to wind the wire rope on N winches;

[0016] The specific steps of this method are:

[0017] S1: The first winch is used as the target winch, the corresponding drum is used as the target drum, and the corresponding motor is used as the driving motor; the Nth winch is used as the transition winch, and the corresponding drum is used as the transition drum;

[0018] Place the target winch, transition winch and wire rope reel in place in sequence, with the transition winch located between the target winch and the wire rope reel, and the target reel and transition reel placed parallel and opposite to each other;

[0019] S2: First, wrap the end of the wire rope on the wire rope drum around the top of the transition drum and wind it several times counterclockwise;

[0020] S3: Then wind the wire rope around the target drum, pass it around the target drum in a counterclockwise direction, and let the rope end pass through the rope hole on the side, and fix it with the rope clamp on the target drum;

[0021] S4: Start the drive motor of the target winch to drive the target drum to rotate counterclockwise; the wire rope between the target drum and the transition drum is gradually tightened; at this time, the friction resistance of the transition drum and the internal resistance of the reducer and motor connected to it are loaded on the wire rope, so that the wire rope is wound around the target drum with load;

[0022] After the steel wire rope on the target drum is wound to a predetermined length, the steel wire rope is disconnected, the rope end at the disconnection is fixed, and the first winch is removed, thereby completing the winding of the steel wire rope on the first winch;

[0023] S5: The Nth winch remains stationary, and the second winch to the (N-1)th winch are used as target winches in sequence; then the method of the above steps S3 and S4 is used to wind the wire rope onto the drum of the corresponding winch;

[0024] After the winding of the wire rope on the (N-1) winch is completed, the wire rope is disconnected and the rope end at the disconnection is fixed; the position of the (N-1) winch is kept unchanged;

[0025] S6: Using the method of step S4 above, the steel wire rope to be wound on the Nth winch is first wound on the (N-1)th winch as a transition steel wire rope;

[0026] S7: Pass the end of the wire rope through the drum of the Nth winch and fix the rope end; then use the drum of the Nth winch as the target drum, drive the motor of the Nth winch, use the drum of the (N-1)th winch as the transition drum, and wind the transition wire rope on the outer layer of the drum of the (N-1)th winch onto the drum of the Nth winch.

[0027] As a preferred embodiment of the present invention: in step S5, after the steel wire rope on the (N-1)th winch is wound to a predetermined length, the steel wire rope is not disconnected, and step S6 is directly continued to wind the transition steel wire rope;

[0028] In step S7, after the transition wire rope is wound onto the drum of the Nth winch, the wire rope is disconnected, and the rope ends at the disconnected positions on the (N-1)th winch and the Nth winch are fixed respectively.

[0029] As a preferred embodiment of the present invention: a support tube is passed through the center of the wire rope reel, both ends of the support tube are supported on a tripod, and the axis of the support tube is parallel to the axis of the target reel and the transition reel; the wire rope reel can rotate around the support tube and release the rope accordingly.

[0030] Beneficial effects:

[0031] (1) The winch wire rope under load winding method of the present invention directly utilizes another winch as a transition loading winch to wind the wire rope onto the winch drum according to the set preload force. The friction resistance of the transition loading drum and the internal resistance of the reducer and motor connected thereto are converted into the preload force of the wire rope, thereby realizing the under load winding of the wire rope. Thus, there is no need to customize special winding equipment.

[0032] (2) In the winch wire rope load winding method of the present invention, during the wire rope winding process, the real-time tension of the wire rope can be calculated by the operating parameters such as the torque of the driving motor; by adjusting the number of winding turns of the wire rope on the transition drum and the clamping force of the transition loading winch's own brake, the increase or decrease of the wire rope pre-tension can be achieved, and finally the wire rope winding pre-tension is basically consistent with or close to the working load value.

[0033] (3) For equipment equipped with multiple winches, the method of the present invention can utilize the existing winches of the equipment, without the need to customize other equipment, to achieve the loaded winding of the wire ropes of several winches.

[0034] (4) During the process of winding the wire rope under load using the method of the present invention, the pre-tension of the wire rope is adjusted and fed back, so that the winding tightness of the wire rope is basically consistent with the normal working condition, the winding is uniform and dense, and the service life of the wire rope is extended; the on-site installation time is saved and the construction period is shortened.

DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Embodiment 1:

[0042] The present embodiment provides a method for winding a winch wire rope with load, which utilizes multiple groups of winches equipped with the equipment itself, two by two in a group, which serve as winding winches and transition loading winches, and winds the wire rope onto the winch drum according to the set pre-tensioning force, thereby eliminating the need to customize special winding equipment.

[0043] The basic idea of ​​this method is: one winch is used as the target winch (i.e. the winding winch), and the other winch is used as the transition loading winch; the motor of the target winch (the motor is the driving motor in this case) is used to drive the drum to rotate and wind the wire rope; the drum of the transition loading winch is used as the transition loading drum of the wire rope to rotate passively. At this time, the friction resistance of the transition loading drum and the internal resistance of the connected reducer and motor are transformed into the pre-tightening force of the wire rope, realizing the loaded winding of the wire rope.

[0044] According to the above method, the loaded winding of the wire rope of the drum of the first, second winch... is completed; when the wire rope is wound on the last winch, the wire rope needs to be wound onto the drum of the second-to-last winch as a transition; then, with the last winch as the driving end, the wire rope on the drum of the second-to-last winch as a transition is reversely wound onto the drum of the last winch; during this process, the drum of the second-to-last winch does not start the motor, and only serves as a passive loading end.

[0045] During the wire rope winding process, the real-time tension of the wire rope can be calculated through the operating parameters such as the torque of the driving motor; the pre-tension of the wire rope can be increased or decreased by adjusting the number of turns of the wire rope on the transition drum and the clamping force of the transition loading winch's own brake, so that the pre-tension of the wire rope winding is basically consistent with or close to the working load value.

[0046] In this way, the existing several sets of winches in the equipment can be used, and there is no need to specially customize other equipment to achieve the loaded winding of several sets of winch wire ropes; and during the winding process, the pre-tension of the wire rope can be basically consistent with the working load through adjustment and feedback, so that the tightness of the wire rope winding is basically consistent with the normal working condition, the winding is uniform and dense, and the service life of the wire rope is extended; the on-site installation time is saved and the construction period is shortened.

[0047] Embodiment 2:

[0048] This embodiment provides a method for winding a steel wire rope of a winch of a sinking shaft boring machine. The method uses three winches of the sinking shaft boring machine in groups of two to wind the steel wire rope onto the winch drum according to a set preload force.

[0049] For the convenience of description, the three winches are respectively called winch A, winch B and winch C, and the winding order is: winch A-winch B-winch B, that is, winch A is the first winch, winch B is the second winch, and winch C is the third winch.

[0050] like Figure 2 As shown, the winch is a conventional winch, comprising: a base 10 and a motor 1 arranged on the base 10, a small reducer 2 connected in sequence with the power output end of the motor 1 to realize power transmission, a coupling 3 and a large reducer 4, a drum 7 connected to the large reducer 4 for winding a wire rope 8, a bearing seat 6 for supporting the drum 7, a rope clamp 9 arranged on the drum 7, and a brake 5 as a winch braking device.

[0051] The wire rope reel 15 is used to provide the wire rope, and the length of the wire rope that the wire rope reel 15 can provide is just enough to meet the winding of the wire rope on the three winches.

[0052] like Figure 3 and Figure 4 As shown, the specific steps of the method are:

[0053] S1: At the beginning of implementation, winch A is used as the target winch 11, the corresponding drum is the target drum 12, and the motor 1 of winch A is the drive motor 17; winch C is used as the transition winch 14, and the corresponding drum is the transition drum 13; the target winch 11, the transition winch 14, and the wire rope reel 15 are placed in place in sequence, wherein the transition winch 14 is located between the target winch 11 and the wire rope reel 15, and the target drum 12 and the transition drum 13 are placed parallel to each other; a steel pipe 19 is passed through the center of the wire rope reel 15, and both ends of the steel pipe 19 are supported on the tripod 16, and the axis of the steel pipe 19 is parallel to the axis of the target drum 12 and the transition drum 13; the wire rope reel 15 can rotate around the steel pipe 19 and follow the rope release.

[0054] S2: First, the rope end of the wire rope on the wire rope drum 15 is wound around the upper part of the transition drum 13, and is wound counterclockwise for several turns (5 turns in this example);

[0055] S3: The steel wire rope is then wound around the target drum 12, and the rope head passes through the rope hole on the side after passing around the target drum 12 in a counterclockwise direction, and is fixed with the rope clamp 9 on the target drum 12.

[0056] S4: Start the drive motor 17 of the target winch 11, drive the target drum 12 to rotate counterclockwise, and gradually tighten the wire rope between the two drums (target drum 12 and transition drum 13); at this time, the friction resistance of the transition drum 13 and the internal resistance of the small reducer 2, motor 1, and large reducer 4 connected to it are all loaded on the wire rope, so that the wire rope is loaded and wound on the target drum 12. After the wire rope on the target drum 12 is wound to a predetermined length (the length of the wire rope required to be wound on winch A), the wire rope is disconnected, and the rope head at the disconnection is fixed, and winch A is removed. In this way, the winding of the wire rope on winch A (i.e., the first winch) is completed.

[0057] In the actual winding process, the target drum 12 is hit with a mallet when winding the wire rope, so that the wire ropes are pressed against each other layer by layer and enter the bottom rope groove.

[0058] S5: Winch C does not move, and winch B (i.e., the second winch) is placed at the position of winch A as the target winch 11. At this time, the drum of winch B is the target drum 12, which is placed parallel to the transition drum 13; then the method of the above steps S3 and S4 is used to wind the wire rope onto the drum of winch B. After the wire rope on the target drum 12 is wound to a predetermined length (the length of the wire rope required to be wound on winch B), the wire rope is disconnected, and the rope end at the disconnection is fixed; thereby completing the winding of the wire rope on winch B (i.e., the second winch); but winch B is not removed at this time.

[0059] S6: Using the method of the above step S4, the steel wire rope to be wound around winch C (i.e., the third winch) is first wound around winch B as a transition (this part of the steel wire rope is called the transition steel wire rope); that is, the steel wire rope to be wound around winch C (i.e., the remaining steel wire rope at this time, including the steel wire rope wound around the drum of winch C in step S2) is first wound around the outside of the steel wire rope on the drum of winch B.

[0060] S7: Pass the rope end of the wire rope through the drum of winch C and fix the rope end; then take the drum of winch C as the target drum, drive the motor of winch C, take the drum of winch B as the transition drum, and wind the transition wire rope on the outer layer of the drum of winch B onto the drum of winch C with load; thus, complete the loaded winding of the wire rope on winch C (i.e. the third winch).

[0061] As another example, in step S5, after the steel wire rope on the target drum 12 is wound to a predetermined length (the length of the steel wire rope required to be wound on winch C), the steel wire rope may not be disconnected first, but directly proceed to step S6 to wind the steel wire rope required to be wound on winch C (i.e., the third winch); that is, the length of the steel wire rope wound on winch B is the sum of the length of the steel wire rope required to be wound on winch B and the length of the steel wire rope required to be wound on winch C (i.e., all the remaining steel wire ropes are wound on winch B, including the steel wire rope wound on the drum of winch C in step S2). Thus, after all the transition steel wire ropes are wound on winch C, the steel wire rope is disconnected, and the rope ends at the disconnection points on winch B and winch C are fixed respectively.

[0062] In the process of winding the wire rope by the above method, when the drum rotates at a uniform speed to wind the wire rope with load, the real-time preload force of the wire rope can be calculated by the working parameters such as the torque of the driving motor. When the preload force is too large, the number of windings of the wire rope on the transition drum can be reduced. At this time, the wire rope and the drum will slide relative to each other, and only a part of the resistance on the transition drum is converted into preload force; when the preload force is insufficient, the number of windings of the wire rope on the transition drum can be increased, and the combined resistance of the transition drum, the motor and the reducer can be completely added to the driving drum. If the preload force still does not reach the required value at this time, the brake 18 of the transition loading winch can be used for loading, and the holding force of the brake can be appropriately adjusted to increase the rotation resistance of the transition drum, thereby increasing the preload force of the wire rope. Therefore, the preload force of the wire rope can be basically consistent with the working load through the adjustment and feedback links, and the winding is very uniform and dense, which can extend the service life of the wire rope. The winch can be used directly on site with the rolled wire, saving on-site installation time and shortening the construction period.

[0063] After the three winches have completed the winding of the loaded wire ropes, when lifting the tunnel boring machine and lowering it synchronously, the speed and stroke of each wire rope can be measured and controlled, which can better keep the tunnel boring machine in a horizontal posture and lower it smoothly. The wire ropes will not bite, stagger, or become tangled, and the tunneling construction will be more stable. This method can be used during the first factory test installation and when replacing new wire ropes during construction, and the winding efficiency is high.

[0064] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
