Description

Technical Field

[0001] This utility model relates to the technical field of mine hoisting equipment, and in particular to a safety-protected vertical shaft bucket, suitable for the safety protection of operators during vertical shaft operations. Background Technology

[0002] Shaft buckets are commonly used transportation tools in mine hoisting systems, primarily for transporting materials or personnel within vertical shafts. Traditional shaft buckets typically consist of a bucket body, lifting lugs, and lifting rings, connected to the hoist via wire ropes for lifting. However, in actual use, the lifting rings, during rapid descent or accidental loss of control, can easily cause collision injuries to operators due to inertia or swaying. Furthermore, the top structure of existing ordinary shaft buckets is usually quite simple, lacking effective limiting and anti-collision designs, resulting in insufficient safety under complex working conditions. Existing ordinary mining buckets lack buffer devices at the connection between the lifting lugs and lifting rings, and there are no effective anti-collision and limiting mechanisms on the top plane of the bucket, posing safety hazards during operation. While some existing buckets employ simple protective measures, these measures are mostly designed to prevent damage to the equipment itself and are insufficient for the safety of construction personnel. They are also difficult to adjust according to different working conditions, and the material strength and durability are generally limited.

[0003] To address the aforementioned issues, several publications have been made, including CN106744221B / CN106800233B Integrated Safety Protection System for Bucket Operation, CN204138113U Integrated Safety Signal Device for Vertical Shafts, CN207608191U A Vehicle-Mounted Signal Device for Vertical Shafts in Mining Areas, and CN102923557B Hook-Type Bucket, as well as improvements to large vertical shaft drilling rigs / slag removal control. These improvements either focus on the bucket structure or on loading / unloading methods and construction safety measures, aiming to increase volume, improve unloading, and reduce manpower through mechanization to enhance safety. However, they do not address the safety of vertical shaft construction personnel or improvements to the bucket structure. All of these improvements suffer from shortcomings such as the risk of collision injuries to operators caused by the rapid descent or swing of the lifting rings.

[0004] Therefore, it is of great significance to develop a safety protection bucket for mining shafts. Summary of the Invention

[0005] The objective of this invention is to overcome existing shortcomings and provide a safe and protective mining shaft hoisting bucket.

[0006] To accomplish the above tasks, this utility model adopts the following technical solution: The safety protection bucket for mining shafts includes a bucket body, lifting lugs, and lifting rings. It also includes limit blocks, anti-collision blocks, fixing seats, and damping descent devices. The damping descent devices are located at the connection between the lifting lugs and the lifting rings. The top surface of the bucket body is equipped with anti-collision blocks and fixing seats, which can effectively prevent the lifting rings from falling rapidly or swinging and causing collision injuries to the operators, forming all-round safety protection.

[0007] Innovation and advantages: (1) Construct a triple collaborative protection system: Through the coordinated action of the damping and slow-descent device at the connection between the lifting lug and the lifting ring, the limiting block at the top of the bucket near the lifting lug, and the anti-collision block on the top surface of the bucket, the lifting ring can be effectively prevented from falling or swinging rapidly and causing collision injury to the operator, thus forming all-round safety protection.

[0008] (2) Optimize the design of the damping and slow-down device: The hydraulic buffer is used as the damping and slow-down device, which includes a hydraulic cylinder, a piston rod and a one-way adjustable flow valve. The two ends of the hydraulic cylinder are fixedly connected to the lifting lug and the lifting ring respectively. The throttle valve provides damping when the lifting ring rises to ensure lifting efficiency, and provides damping when it falls to achieve slow-down, taking into account both efficiency and safety.

[0009] (3) Upgraded limit and anti-collision component structure: The limit block and anti-collision block are both made of wear-resistant tempered steel containing chromium, molybdenum and vanadium, which has high yield strength and impact resistance; the modular and detachable structure is adopted, and it is installed on the fixed seat by bolts or pins, and different specifications can be replaced to adapt to working conditions; the anti-collision block is designed to be arc-shaped and fits the top edge of the barrel, providing more comprehensive protection.

[0010] (4) Focus on personnel safety protection: Breaking through the limitations of existing technologies that focus on equipment damage protection, the core of the design is clearly directed towards the safety of operators. Through targeted structural design, it fills the gap in the traditional bucket's insufficient protection of construction personnel safety.

[0011] Compared with the prior art, this utility model has the following advantages or effects: Because of the damping descent device, the descent speed of the lifting ring can be slowed down, reducing the risk of collision; at the same time, due to the limit blocks and anti-collision blocks, they can be flexibly replaced to adapt to different working conditions; in addition, due to the arc design of the anti-collision blocks, the swinging lugs can effectively prevent them from swinging and hitting the bucket or operators. The multi-layered safety protection system can significantly improve the safety performance of the vertical shaft bucket. Attached Figure Description

Damping descent device The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Detailed Implementation

[0016] like Figures 1-2 As shown, the safety protection bucket for mining shafts provided by this utility model includes a bucket body 1, lifting lugs 2, and lifting rings 3. It also includes a limiting block 4, a collision protection block and a fixing seat 5, and a damping descent device 6. The damping descent device 6 is located at the connection between the lifting lugs 2 and the lifting rings 3. The top surface of the bucket body 1 is provided with a collision protection block and a fixing seat 5, which can effectively prevent the lifting rings 3 from falling or swinging rapidly and causing collision injuries to the operators, thus forming all-round safety protection.

[0017] This utility model can be further described as follows: The damping and slow-descent device 6 includes a hydraulic cylinder, a piston rod, and a one-way adjustable flow valve. The throttle valve provides damping when the lifting ring rises to ensure lifting efficiency, and provides damping when it descends to achieve a slow descent, thus balancing efficiency and safety.

[0018] There are two damping and slow-descent devices 6 located at the connection between the lug 2 and the ring 3.

[0019] There are two limiting blocks 4 located on both sides of the two lugs 2.

[0020] Four anti-collision blocks and fixing seats 5 are evenly distributed on the top surface of the barrel body 1.

[0021] The anti-collision block and the fixing seat 5 are designed to be arc-shaped and fit against the top edge of the barrel body 1, providing more comprehensive protection.

[0022] The limiting block 4, the anti-collision block, and the fixing seat 5 are all made of wear-resistant tempered steel containing chromium, molybdenum, and vanadium with high yield strength and impact resistance. Example

[0023] Please see Figure 1 and Figure 2A mining shaft hoisting bucket with safety protection design includes a bucket body 1, lifting lugs 2, lifting rings 3, a damping descent device 6, limiting blocks 4, anti-collision blocks 5, and a fixed base. The bucket body 1 is a cylindrical structure and serves as the main holding part of the bucket for loading materials or personnel. The lifting lugs 2 are fixedly connected to the top of the bucket body 1, forming a triangular support structure, and are connected to the lifting rings 3 through the damping descent device 6 to achieve the lifting function. The damping descent device 6 is installed at the connection between the lifting lugs 2 and the lifting rings 3, and is preferably a hydraulic damper, including a hydraulic cylinder, a piston rod, and a throttle valve. The two ends of the hydraulic cylinder are fixedly connected to the lifting lugs 2 and the lifting rings 3 respectively, and the hydraulic damping slows down the descent speed of the lifting rings 3 to prevent collision injuries caused by the rapid descent of the lifting rings. Several limiting blocks 4 are provided on the top of the bucket body 1 near the lifting lugs 2, and are installed on the fixed base and can be detachably connected by bolts or pins. The limiting block 4 is made of wear-resistant tempered steel containing chromium, molybdenum, and vanadium, possessing high yield strength and impact resistance. Different heights, sizes, and models can be replaced according to working conditions to limit the swing range of the lifting ring 3. Anti-collision blocks 5 are evenly distributed on the top surface of the barrel 1, forming an arc-shaped structure and fitted snugly against the top edge of the barrel 1. They are made of the same high-strength alloy steel material to prevent the lifting lug 2 from impacting the outside of the barrel 1 or the operator when swinging.

[0024] The throttle valve adopts a one-way adjustable structure and is installed in the damping and slow-descent device 6. It provides no damping when the lifting ring 3 rises and provides a slow-descent effect when it descends, thereby optimizing and improving efficiency and ensuring safety during the descent process.

[0025] The working principle of this safety-protected mining shaft hoisting bucket is as follows: The lifting ring 3 is connected to the hoist via a steel wire rope, and the lifting lug 2 and the bucket 1 work together to bear the load. When the hoist starts, the lifting ring 3 drives the bucket 1 to rise or fall. The damping descent device 6 slows down the descent speed, the limit block 4 limits the swing amplitude of the lifting ring 3, and the anti-collision block 5 provides physical protection to prevent the lifting lug 2 from hitting the bucket 1 or the operator, thereby improving overall safety.

[0026] Unlike existing technologies, this utility model features a mining shaft hoist bucket with safety protection design. Through the coordinated action of the damping descent device 6, the limiting block 4, and the anti-collision block 5, it effectively prevents the hoisting ring 3 from falling rapidly or swinging and causing injury to the operator, significantly improving the safety performance and adaptability of the hoist bucket.

[0027] In a preferred embodiment of this utility model, the high-strength alloy steel material is a wear-resistant quenched and tempered steel containing chromium, molybdenum, and vanadium, which has high yield strength and impact resistance, and can withstand the impact load during the lifting process.

[0028] In a preferred embodiment of this utility model, the damping descent device is a hydraulic buffer, including a hydraulic cylinder, a piston rod and a throttle valve. The two ends of the hydraulic cylinder are fixedly connected to the lug and the lifting ring respectively, and the buffering effect is achieved when the lifting ring descends through hydraulic damping.

[0029] In a preferred embodiment of this utility model, the limiting block is installed on a fixed seat on the top of the barrel and is detachably connected by bolts or pins, which facilitates the replacement of limiting blocks of different specifications according to actual working conditions.

[0030] In a preferred embodiment of this utility model, the anti-collision block has an arc-shaped structure and is installed in close contact with the top edge of the barrel to prevent the lifting lug from hitting the outside of the barrel or the operator when it swings, thereby improving operational safety.

[0031] In a preferred embodiment of this utility model, the throttle valve has a one-way adjustable structure, which provides damping and slowing effect when the lifting ring rises and when the lifting ring descends, thereby optimizing and improving efficiency and ensuring safety during the descent process.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
