Description

Technical Field

[0001] The present 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] Lowering the head rope and hoist container in a hoisting system using a friction hoist is a critical process in hoist system installation. In mine operations, the hoisting system is crucial for transporting personnel, materials, and equipment up and down the mine, making it one of the core systems of mine operations. As crucial components of the hoisting system, the performance and condition of the wire rope and hoist container directly impact the safety and efficiency of the hoisting system.

[0003] In existing lowering systems, the conventional construction method involves lowering the hoist container downhole to the bottom of the well using a wellhead-mounted stabilizing vehicle. The surface hoist container is then hung on the surface, and the hoist leader ropes are then wrapped around the stabilizing vehicle. The leader ropes are lowered one at a time until all the leader ropes are lowered. During the lowering of the container and leader ropes, personnel must monitor the process, as there is a risk of the leader rope becoming entangled with the already deployed leader rope.

[0004] To address the existing problem of the head rope becoming tangled during a single lowering operation, the head rope can be separately wound around a well-sinking stabilization vehicle, then connected to a lifting container using an automatic tension balancing device. The stabilization vehicle is then started to lower the head rope and the lifting container to the well bottom at once. This eliminates the need to secure the lifting container at the well bottom, and the head rope is lowered into place all at once, preventing tangling. This significantly improves construction efficiency and reduces construction time.

[0005] However, during the lowering of the lead rope and hoisting container, the temperature in deep wells increases with depth. The high temperature environment will affect the material properties of the wire rope and container, reducing their strength and load-bearing capacity, which may cause the wire rope and container to break and be damaged. 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 in a deep well, which solves the technical problem of the wire rope and the lifting container being broken due to high temperature.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A device for lowering a steel wire rope and container in a deep well, and a method for lowering the same, includes an automatic tension balancing device, the interior of the automatic tension balancing device also including a wedge-shaped ring, the exterior of the wedge-shaped ring being wrapped with a steel wire rope body, the steel wire rope body passing through the top of the automatic tension balancing device, a protective frame provided on the side of the automatic tension balancing device, a motor fixedly connected to the inner wall of the protective frame on the side away from the automatic tension balancing device, and a cooling mechanism provided on the side of the motor close to the automatic tension balancing device, the cooling mechanism being used to cool the automatic tension balancing device and the steel wire rope body. This ensures that the automatic tension balancing device and the steel wire rope body will not deform or break due to the high temperature underground.

[0009] As a further improvement of the present invention, four automatic tension-balancing devices are provided, each of which has its bottom end movably connected to the lifting container body. Each of the automatic tension-balancing devices is fixedly connected to a connecting block on the side closest to the protective frame, and each of the connecting blocks is fixedly connected to the outer surface of the protective frame on the side away from the automatic tension-balancing device. This provides a protective effect for the entire device.

[0010] As a further improvement of the present invention, a plurality of support and protection rods are evenly arranged in a circular pattern on the inner wall of the protection frame. A sleeve ring is fixedly connected to the middle portion of the support and protection rods on the side closest to each other. The sleeve ring is mounted on the outside of the cooling mechanism. A through rod is fixedly connected to the output end of the motor on the side closest to the automatic tension balancing device. This allows the motor to control the rotation of the cooling mechanism.

[0011] As a further improvement of the present invention, the end of the through-rod remote from the motor is fixedly connected to a mounting bracket, which is fixedly connected to the interior of the cooling mechanism. A water pipe is provided on the exterior of the through-rod, and the side of the water pipe proximal to the automatic tension balancing device is rotatably connected to the cooling mechanism. Thus, when cooling water is supplied to the cooling mechanism through the water pipe, the normal operation of the device is not affected.

[0012] As a further improvement of the present invention, the cooling mechanism includes a fixed tube, the exterior of which is fixedly connected to a wind blowing structure, a rotating ring fixedly connected to the side of the fixed tube close to the water pipe, the rotating ring rotatably connected to the interior of the water pipe, and spray pipes fixedly connected to both ends of the fixed tube away from the rotating ring. This ensures that the cooling mechanism does not interfere with the water pipe during rotation.

[0013] As a further improvement to the present invention, a plurality of water outlet holes are evenly distributed on the side of the spray pipe away from the air blowing structure. A rotating rod is rotatably connected to the side of the fixed pipe away from the rotating ring. The end of the rotating rod away from the fixed pipe is fixedly connected to a fixed rod. The end of the fixed rod away from the rotating rod is fixedly connected to the side of the automatic tension balancing device near the protective frame. This ensures that the device and the automatic tension balancing device are fixedly secured, thereby preventing the automatic tension balancing device from shifting.

[0014] A method for lowering a wire rope and a container in a deep well, comprising the following steps:

[0015] S1; Winding before lowering: Wind the four lifting ropes onto the well-drilling stabilizing vehicle respectively, and then connect them with the lifting container using the automatic tension balancing device. Use stabilizing vehicles of the same specifications and models to wind the ropes separately to ensure synchronization during the lowering process.

[0016] 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. 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.

[0017] 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.

[0018] As a further improvement of the present invention, in step S2, the connection between the head rope and the lifting container uses 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.

[0019] As a further improvement of the present invention, in step S2, personnel monitor the synchronization of the main body of the wire rope throughout the whole process, and when the main body of the wire rope is not lowered synchronously, the clamp is promptly adjusted to ensure the synchronization of the lowering of multiple wire ropes.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The motor activates the spray pipe, which rotates through the fixed pipe, spray pipe, and water outlet. When water accumulates in the spray pipe of the water pipe box, the rotating spray pipe sprays water from the outlet onto the surface of the automatic tension balancing device and the wire rope body. This cools the wire rope body, which experiences increasing temperatures as it descends. Temperatures in deep wells rise with depth, and the wire rope body can generate significant heat due to friction and mechanical energy conversion during high-speed lowering or prolonged use. Prompt cooling effectively prevents overheating and performance degradation of the wire rope body. Cooling also helps maintain the stability and effectiveness of the lubricant, extending the life of the wire rope body. Furthermore, the wire rope body plays a crucial safety role during lifting and transportation. Overheating and failure of the wire rope body can result in accidents such as falling objects. Cooling helps maintain the stability and reliability of the wire rope body, reducing safety risks.

[0022] 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 air 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 in a humid environment for a long time. 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.

[0023] 3. Through the automatic tension balancing device, the connecting block and the protective frame, due to the fixed connection between the automatic tension balancing device, the connecting block and the protective frame, the distance between multiple automatic tension balancing devices can be limited while providing fixed support for the protective frame, thereby achieving the effect of fixing the lateral position during the simultaneous lowering of multiple steel wire rope bodies. The fixed lateral position can prevent the steel wire rope bodies from getting entangled with each other during the lowering process, reducing 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 steel wire rope body, avoiding lowering difficulties or safety accidents caused by uneven speeds. The fixed lateral position can also keep the steel wire rope body in a relatively fixed position during the lowering process, making it easier for staff to observe and monitor its status.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0033] The present invention provides a technical solution: a device for lowering steel wire ropes and containers in deep wells, comprising an automatic tension balancing device 1, the interior of the automatic tension balancing device 1 also comprising a wedge ring 101, the outside 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 protective frame 5 is provided on the side of the automatic tension balancing device 1, a motor 8 is fixedly connected to the side of the inner wall of the protective frame 5 away from the automatic tension balancing device 1, and a cooling mechanism 9 is provided on the side of the motor 8 close to the automatic tension balancing device 1.

[0034] 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 protective frame 5 is fixedly connected to a connecting block 4, and the end of the connecting block 4 away from the automatic tension balancing device 1 is fixedly connected to the outer surface of the protective frame 5. The inner wall of the protective frame 5 is evenly arranged in a circle with a number of supporting protection rods 6, and the middle part of the supporting protection 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 and cooling mechanism 9. The output end of the motor 8 close to 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 bracket 12, and the fixing bracket 12 is fixedly connected to the inside of the cooling and cooling mechanism 9. A water pipe 10 is provided on the outside of the through rod 11, and the water pipe 10 is rotatably connected to the cooling and cooling mechanism 9 on the side close to the automatic tension balancing device 1. All the wire rope bodies 2 are wound around the well-drilling stabilization vehicle, and then connected to the lifting container body 3 using the automatic tension balancing device 1. The stabilization vehicle is then started, and the wire rope bodies 2 and the lifting container body 3 are lowered to the well bottom at once. With this method, the lifting container body 3 does not need to be fixed separately at the well bottom, and the wire rope bodies 2 are lowered into place at once, thus avoiding the possibility of entanglement. This greatly improves construction efficiency and reduces construction time.

[0035] like Figure 6As shown, the cooling mechanism 9 includes a fixed tube 902, the exterior of which is fixedly connected to a wind blowing structure 901. The side of the fixed tube 902 near the water pipe 10 is fixedly connected to a rotating ring 903, which is rotatably connected to the interior of the water pipe 10. The fixed tube 902, away from the rotating ring 903, has both ends fixedly connected to a spraying pipe 904. The spraying pipe 904 has a plurality of water outlet holes 905 evenly formed on the side away from the wind blowing structure 901. The side of the fixed tube 902 away from the rotating ring 903 is rotatably connected to a rotating rod 906. The end of the rotating rod 906 away from the fixed tube 902 is fixedly connected to a fixed rod 907, a sleeve ring 7 of the cooling mechanism 9. The end of the sleeve ring 7 of the cooling mechanism 9 away from the rotating rod 906 is fixedly connected to the side of the automatic tension balancing device 1 near 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.

[0036] The effect achieved by the entire 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 front ends of the fixed pipe 902 are fixedly connected to the wind blowing structure 901 and the spray pipe 904 respectively, and the surface of the spray pipe 904 is provided with a plurality of water outlets 905, the surface of the automatic tension balancing device 1, the steel wire rope body 2 and the lifting container body 3 can be water-cooled. Timely cooling can effectively prevent the performance of the steel wire rope body 2 from being degraded due to overheating, and the wind blowing from the wind blowing structure 901 can accelerate the evaporation of water on the surface of the steel wire rope body 2, thereby taking away more heat and preventing corrosion and wear on the surface of the steel wire 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 with the fixed rod 907 cooling mechanism 9 sleeve ring 7, the rotation effect will not be hindered while being fixed.

[0037] 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, so that the lateral position can be fixed during the lowering process of the multiple automatic tension balancing devices 1 and the steel wire rope body 2. The fixed lateral position can prevent the steel wire rope body 2 from being entangled with each other during the lowering process, thereby reducing safety hazards and accident risks caused by entanglement.

[0038] The present invention also provides a method for lowering a steel wire rope and a container in a deep well, the specific steps comprising:

[0039] Step 1: Winding before lowering: Wind the four lifting ropes around the first steady car, and then use the tension automatic balancing device 1 and the lifting container to connect together, and use the same specifications and models of steady cars to wind the first ropes to ensure synchronization during the lowering process.

[0040] 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.

[0041] Step three: cooling during the process: while lowering the first lifting rope and the lifting container, start the motor 8 and spray the surface of the first rope and the lifting container, thereby cooling the first rope and the lifting container during the descent process.

[0042] 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 rope body 2 and the lifting container body 3 adopts an automatic tension balancing device 1 to ensure that each steel wire rope body 2 is evenly stressed during the lowering process, and personnel monitor the synchronization of the steel wire rope body 2 throughout the process. When the lowering of the steel wire 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 rope body 2. It can also ensure synchronous operation when multiple steel wire rope bodies 2 are lowered. This method effectively shortens the construction time of lowering the steel wire 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.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
