Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope lowering, and in particular to a lowering device and a lowering method for a steel wire rope and a container in a deep well. Background Art

[0002] The lowering of the first rope and lifting container of the hoisting system using a friction hoist is a key process in the installation of the hoisting system. In mine production, the hoisting system undertakes the important task of getting personnel, materials and equipment up and down the mine, and is one of the core systems of mine production. As important components of the hoisting system, the performance and status of the wire rope and lifting container directly affect the safety and efficiency of the hoisting system.

[0003] In the existing lowering device, the conventional construction method is to lower the underground lifting container to the bottom of the well using the well-drilling stabilizing vehicle installed at the wellhead, hang the surface lifting container on the surface, and then wrap the lifting leader rope around the well-drilling stabilizing vehicle, lowering one leader rope at a time until all the leader ropes are lowered. During the lowering process of the container and the leader rope, personnel must also monitor, as there is a possibility that the leader rope will be entangled with the leader rope that has been set during the lowering process.

[0004] In order to solve the problem that the first rope may be entangled during a single lowering process in the prior art, the first rope can be wound around the well-drilling stabilizing vehicle, and then the tension automatic balancing device and the lifting container are connected together, and then the stabilizing vehicle is started to lower the first rope and the lifting container to the bottom of the well at one time, so that the lifting container does not need to be fixed separately at the bottom of the well, and the first rope is lowered in place at one time to avoid the possibility of entanglement. This greatly improves the construction efficiency and reduces the construction time.

[0005] However, during the lowering of the head rope and lifting container, the temperature in the deep well will increase with the increase of depth, and the high temperature environment will affect the material properties of the wire rope and container, reducing their strength and carrying capacity, which may cause the risk of wire rope and container breakage and damage. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a lowering device and a lowering method for a wire rope and a container for a deep well, which solves the technical problem of breakage of the wire rope and the lifting container due to high temperature.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A device for lowering a steel wire rope and a container in a deep well and a method for lowering the same, comprising an automatic tension balancing device, wherein the interior of the automatic tension balancing device also includes a wedge ring, the exterior of the wedge ring is wrapped with a steel wire lead rope body, the steel wire lead rope body passes through the top of the automatic tension balancing device, a protection frame is provided on the side of the automatic tension balancing device, a motor is fixedly connected to the inner wall of the protection frame on the side away from the automatic tension balancing device, a cooling mechanism is provided on the side of the motor close to the automatic tension balancing device, and the cooling mechanism is used to cool the automatic tension balancing device and the steel wire lead rope body. This ensures that the automatic tension balancing device and the steel wire lead rope body will not be deformed or broken due to the high temperature underground.

[0008] As a further improvement of the present invention, four automatic tension balancing devices are provided, and the bottom ends of the four automatic tension balancing devices are movably connected to the lifting container body. The side of the automatic tension balancing device close to the protection frame is fixedly connected to a connecting block, and the end of the connecting block away from the automatic tension balancing device is fixedly connected to the outer surface of the protection frame. This can provide a protective effect for the entire device.

[0009] As a further improvement of the present invention, the inner wall of the protection frame is evenly arranged with a plurality of supporting protection rods in a circular shape, the middle part of the supporting protection rods close to each other is fixedly connected with a sleeve ring, the sleeve ring is sleeved on the outside of the cooling mechanism, and the output end of the motor close to the tension automatic balancing device is fixedly connected with a through rod. Thus, the cooling mechanism can be controlled to rotate by the motor.

[0010] As a further improvement of the present invention, the end of the through rod away from the motor is fixedly connected to a fixing frame, the fixing frame is fixedly connected to the inside of the cooling mechanism, a water pipe is arranged outside the through rod, and the side of the water pipe close to the automatic tension balancing device is rotatably connected to the cooling mechanism. Therefore, when cooling water is transported to the cooling mechanism through the water pipe, the normal operation of the device will not be affected.

[0011] As a further improvement of the present invention, the cooling mechanism includes a fixed pipe, the outside of the fixed pipe is fixedly connected with a wind blowing structure, the side of the fixed pipe close to the water pipe is fixedly connected with a rotating ring, the rotating ring is rotatably connected to the inside of the water pipe, and both ends of the fixed pipe away from the rotating ring are fixedly connected with spraying pipes. This ensures that the cooling mechanism will not conflict with the water pipe when rotating.

[0012] As a further improvement of the present invention, a plurality of water outlet holes are evenly opened on the side of the spray pipe away from the wind blowing structure, a rotating rod is rotatably connected to the side of the fixed pipe away from the rotating ring, a fixed rod is fixedly connected to the end of the rotating rod away from the fixed pipe, and the end of the fixed rod away from the rotating rod is fixedly connected to the side of the automatic tension balancing device close to the protection frame. This ensures that the device is fixed to the automatic tension balancing device, thereby achieving the effect of preventing the automatic tension balancing device from positional displacement.

[0013] A method for lowering a steel wire rope and a container in a deep well, the specific steps comprising: S1; Winding before lowering: Wind the four lifting ropes on the well-drilling stabilizing vehicle respectively, and then connect them with the lifting container using the automatic tension balancing device, and use the stabilizing vehicle of the same specifications and models to wind the ropes respectively to ensure synchronization during the lowering process.

[0014] S2; Lowering process: Start the stabilizing vehicle and lower the first lifting rope and the lifting container to the bottom of the well at one time. With this method, the lifting container does not need to be fixed separately at the bottom of the well, and the first rope is lowered into place at one time to avoid the possibility of entanglement.

[0015] S3; Cooling during the process: while lowering the first hoisting rope and the hoisting container, the motor is started to spray the surface of the first rope and the hoisting container, thereby cooling the first rope and the hoisting container during the descent process.

[0016] As a further improvement of the present invention, in step S2, the connection between the head rope and the lifting container adopts an automatic tension balancing device to ensure that each wire rope is evenly stressed during the lowering process, thereby preventing serious accidents such as wire breakage, strand breakage or rope breakage.

[0017] As a further improvement of the present invention, in step S2, the personnel monitor the synchronization of the main body of the steel wire rope throughout the whole process, and when the main body of the steel wire rope is not lowered synchronously, the clamp should be used to adjust it in time, so as to ensure the synchronization of the lowering of multiple steel wire ropes.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the fixed pipe, spray pipe and water outlet, the motor is started to drive the spray pipe to rotate. When water is stored in the spray pipe of the water pipe box, the water will be sprayed from the water outlet to the surface of the tension automatic balancing device and the wire rope body through the rotation of the spray pipe, so that the wire rope body can be cooled in an environment where the temperature increases as it goes down. Since the temperature in the deep well increases with the depth, and the wire rope body may generate a lot of heat due to friction and mechanical energy conversion during high-speed lowering or long-term use, timely cooling can effectively prevent the performance of the wire rope body from degrading due to overheating. Cooling also helps to maintain the stability and effectiveness of the grease and extend the service life of the wire rope body. In addition, the wire rope body plays an important safety role during lifting and transportation. If the wire rope body fails due to overheating, it may cause safety accidents such as heavy objects falling. Cooling helps to maintain the stability and reliability of the wire rope body and reduce safety risks.

[0019] 2. Through the wind blowing structure, while the motor drives the spray pipe to rotate, it will also drive the wind blowing structure to rotate rapidly. Sprinkling water directly reduces the temperature of the surface of the wire rope body, while blowing through the wind blowing structure can accelerate the evaporation of water on the surface of the wire rope body, thereby taking away more heat. This dual effect can significantly improve the cooling effect, allowing the wire rope body to return to a lower temperature state in a short time. In addition, the wire rope body may cause moisture accumulation when working for a long time in a humid environment. Wind blowing can accelerate the evaporation of moisture on the surface of the wire rope body, keep its surface relatively dry, and reduce the risk of corrosion and wear. If the surface of the wire rope body is coated with grease, wind blowing can also help remove excess moisture and impurities, thereby keeping the grease clean and effective, thereby improving the lubrication effect and service life of the wire rope body.

[0020] 3. Through the tension automatic balancing device, the connection block and the protection frame, due to the fixed connection between the tension automatic balancing device, the connection block and the protection frame, the distance between multiple tension automatic balancing devices can be limited while the protection frame is fixed and supported, so that the lateral position can be fixed during the simultaneous lowering of multiple wire head rope bodies. The fixed lateral position can prevent the wire head rope bodies from being entangled with each other during the lowering process, reducing the safety hazards and accident risks caused by entanglement. In addition, the fixed lateral position helps to maintain the consistency of the lowering speed of each wire head rope body, avoiding lowering difficulties or safety accidents caused by uneven speeds. The fixed lateral position can also make the wire head rope body in a relatively fixed position during the lowering process, which is convenient for staff to observe and monitor its status.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] The present invention provides a technical solution: a device for lowering a steel wire rope and a container in a deep well, comprising an automatic tension balancing device 1, the interior of the automatic tension balancing device 1 also comprising a wedge ring 101, the exterior of the wedge ring 101 is wrapped with a steel wire head rope body 2, the steel wire head rope body 2 passes through the top of the automatic tension balancing device 1, a protection frame 5 is arranged on the side of the automatic tension balancing device 1, a motor 8 is fixedly connected to the inner wall of the protection frame 5 on the side away from the automatic tension balancing device 1, and a cooling mechanism 9 is arranged on the side of the motor 8 close to the automatic tension balancing device 1.

[0031] like Figure 1-5 As shown, four automatic tension balancing devices 1 are provided, and the bottom ends of the four automatic tension balancing devices 1 are movably connected to the lifting container body 3. The side of the automatic tension balancing device 1 close to the protection frame 5 is fixedly connected to the connection block 4, and the end of the connection block 4 away from the automatic tension balancing device 1 is fixedly connected to the outer surface of the protection frame 5. The inner wall of the protection frame 5 is evenly arranged with a plurality of supporting and protective rods 6 in a circular shape, and the middle part of the supporting and protective rods 6 close to each other is fixedly connected to a sleeve ring 7, and the sleeve ring 7 is sleeved on the outside of the cooling mechanism 9. The output end of the motor 8 close to the side of the automatic tension balancing device 1 is fixedly connected to a through rod 11. The end of the through rod 11 away from the motor 8 is fixedly connected to a fixing frame 12, and the fixing frame 12 is fixedly connected to the inside of the cooling mechanism 9. The outside of the through rod 11 is provided with a water pipe 10, and the side of the water pipe 10 close to the automatic tension balancing device 1 is rotatably connected to the cooling mechanism 9. All the steel wire lead rope bodies 2 are wound around the well-drilling stabilizing vehicle, and then connected together by the tension automatic balancing device 1 and the lifting container body 3, and then the stabilizing vehicle is started, and the steel wire lead rope body 2 and the lifting container body 3 are lowered to the bottom of the well at once. With this method, the lifting container body 3 does not need to be fixed separately at the bottom of the well, and the steel wire lead rope body 2 is lowered into place at once, thereby avoiding the possibility of winding. This greatly improves the construction efficiency and reduces the construction time.

[0032] like Figure 6As shown, the cooling mechanism 9 includes a fixed pipe 902, the outside of which is fixedly connected with a wind blowing structure 901, a rotating ring 903 is fixedly connected to the side of the fixed pipe 902 close to the water pipe 10, and the rotating ring 903 is rotatably connected to the inside of the water pipe 10, and both ends of the fixed pipe 902 away from the rotating ring 903 are fixedly connected to a spray pipe 904. A plurality of water outlet holes 905 are evenly opened on the side of the spray pipe 904 away from the wind blowing structure 901, a rotating rod 906 is rotatably connected to the side of the fixed pipe 902 away from the rotating ring 903, and a fixed rod 907 is fixedly connected to the cooling mechanism 9 sleeve ring 7 at one end of the rotating rod 906 away from the fixed pipe 902, and the fixed rod 907 is fixedly connected to the cooling mechanism 9 sleeve ring 7 at one end of the cooling mechanism 9 sleeve ring 7 away from the rotating rod 906 at one end of the automatic tension balancing device 1 close to the protective frame 5. The invention solves the problem that the temperature in a deep well increases with the depth, and the heat generated by the friction of the steel wire rope body 2 causes the steel wire rope and the lifting container to break.

[0033] The effect achieved by the whole device is as follows: first, when the tension automatic balancing device 1, the steel wire rope body 2 and the lifting container body 3 are lowered, the motor 8 is started at the same time. Since the output end of the motor 8 is fixedly connected to the through rod 11, and the through rod 11 penetrates the outside of the water pipe 10, it will not affect the water inlet of the water pipe 10. Since the outer surface of the fixing frame 12 fixedly connected to the other end of the through rod 11 is fixedly connected to the fixed pipe 902, the motor 8 will drive the fixed pipe 902 to rotate. Since the rotating ring 903 fixedly connected to the side of the fixed pipe 902 is rotatably connected to the water pipe 10, the fixed pipe 902 The rotation will not cause the water pipe 10 to twist. Since the outside and the front sides of the fixed pipe 902 are respectively fixedly connected to the wind blowing structure 901 and the spray pipe 904, and the surface of the spray pipe 904 is provided with a plurality of water outlet holes 905, the surface of the automatic tension balancing device 1, the steel wire head rope body 2 and the lifting container body 3 can be water-cooled. Timely cooling can effectively prevent the performance of the steel wire head rope body 2 from being degraded due to overheating, and the wind blowing of the wind blowing structure 901 can accelerate the evaporation of water on the surface of the steel wire head rope body 2, thereby taking away more heat and preventing corrosion and wear on the surface of the steel wire head rope body 2. Since the rotating rod 906 rotatably connected to the front end of the fixed pipe 902 is fixedly connected to the automatic tension balancing device 1, the cooling mechanism 9 sleeve ring 7 of the fixed rod 907 can be fixed without hindering the rotation effect.

[0034] And due to the sequential fixed relationship between the automatic tension balancing device 1, the connecting block 4 and the protective frame 5, the automatic tension balancing device 1 can provide a fixed support to the protective frame 5, while the protective frame 5 also limits the distance between the multiple automatic tension balancing devices 1, thereby achieving the goal of fixing the lateral position during the lowering of the multiple automatic tension balancing devices 1 and the steel wire head rope body 2. The fixed lateral position can prevent the steel wire head rope body 2 from being entangled with each other during the lowering process, thereby reducing safety hazards and accident risks caused by entanglement.

[0035] The present invention also provides a method for lowering a steel wire rope and a container in a deep well, the specific steps comprising: Step 1: Winding before lowering: Wind the four lifting ropes around the well-drilling stabilizing vehicle, and then connect the lifting container with the tension automatic balancing device 1, and use the stabilizing vehicle of the same specifications and models to wind the first ropes to ensure synchronization during the lowering process.

[0036] Step 2: Lowering process: Start the stabilizing vehicle and lower the first lifting rope and the lifting container to the bottom of the well at one time. Using this method, the lifting container does not need to be fixed separately at the bottom of the well, and the first rope is lowered into place at one time to avoid the possibility of entanglement.

[0037] Step three: Cooling during the process: while lowering the first lifting rope and the lifting container, start the motor 8 to spray the surface of the first rope and the lifting container, so as to cool the first rope and the lifting container during the descent.

[0038] The entire method for lowering steel wire ropes and containers for deep wells is roughly the same as a device for lowering steel wire ropes and containers for deep wells. The main difference is that the connection between the steel wire head rope body 2 and the lifting container body 3 adopts an automatic tension balancing device 1 to ensure that each steel wire head rope body 2 is evenly stressed during the lowering process, and personnel monitor the synchronization of the steel wire head rope body 2 throughout the process. When the lowering of the steel wire head rope body 2 is not synchronized, it must be adjusted in time through the clamp to prevent serious accidents such as wire breakage, strand breakage or rope breakage of the steel wire head rope body 2. It can also ensure synchronous operation when multiple steel wire head rope bodies 2 are lowered. This method effectively shortens the construction time of lowering the steel wire head rope body 2 and the lifting container body 3 during the installation of the lifting system, increases the safety and reliability of the construction process, improves work efficiency, and reduces construction costs.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
