Description

矿井提升摩擦衬垫防滑性能测试装置及方法Device and method for testing anti-skid performance of friction pads in mine 技术领域Technical field
本发明涉及一种摩擦衬垫防滑性能测试装置及方法，尤其是一种适用于矿井提升的摩擦衬垫防滑性能测试装置及方法。The invention relates to a friction lining anti-skid performance testing device and method, in particular to a friction lining anti-skid performance testing device and method suitable for mine lifting.
背景技术Background technique
立井提升机作为主要的矿井提升装备，担负着提升煤炭矸石、下放材料、升降人员和设备的重要任务，是煤矿井下与地面的连接枢纽，其中摩擦提升占据主导地位。摩擦衬垫安装在卷筒表面，利用与钢丝绳之间的摩擦力拖动提升容器上下。当摩擦衬垫失效时，钢丝绳与摩擦衬垫之间会发生相对滑动，造成钢丝绳磨损，甚至造成提升容器打滑坠落等重大恶性事故。因而摩擦衬垫防滑性能的好坏直接关系到提升机能否可靠提升。然而，摩擦衬垫属于易损易耗件，随着煤矿生产的进行，摩擦衬垫会不断磨损。《煤矿安全规程》规定，多绳摩擦衬垫的剩余磨损厚度不得小于钢丝绳直径，磨损深度不得超过70毫米。一旦磨损超限，则需及时更换。更换摩擦衬垫时，需要对摩擦衬垫进行严格的防滑性能测试，避免新衬垫降低提升系统的防滑性能。As the main mine lifting equipment, the vertical shaft hoist is responsible for the important tasks of lifting coal gangue, lowering materials, lifting personnel and equipment. It is the connection hub between the underground coal mine and the ground, in which friction lifting occupies a dominant position. The friction pad is installed on the surface of the drum, and the frictional force with the steel wire rope is used to drag the lifting container up and down. When the friction liner fails, relative slippage occurs between the steel wire rope and the friction liner, causing the steel wire to wear out, and even causing major vicious accidents such as the slipping and falling of the lifting container. Therefore, the quality of the anti-skid performance of the friction pad is directly related to whether the hoist can be reliably lifted. However, friction pads are consumables and consumables. As coal mine production progresses, friction pads will continue to wear out. "Coal Mine Safety Regulations" stipulates that the remaining wear thickness of multi-rope friction pads shall not be less than the diameter of the wire rope, and the wear depth shall not exceed 70 mm. Once the wear exceeds the limit, it needs to be replaced in time. When replacing the friction lining, strict anti-slip performance testing of the friction lining is required to avoid the new lining reducing the anti-slip performance of the lifting system.
目前，由于摩擦衬垫的生产厂商众多，采用的制造工艺和生产标准不尽相同，而衬垫的测试缺乏一个统一的装置和标准。由于煤矿的地质条件多样，对提升载荷、提升速度也产生了不同需求，由此产生了不同卷筒和钢丝绳直径的摩擦提升机，进而决定了贴装在卷筒表面的摩擦衬垫的绳槽弧度和直径，由此产生了不同规格的摩擦衬垫，导致对衬垫防滑性能测试难以采用统一的装置。如果针对不同规格的摩擦衬垫分别搭建测试装置，将会产生较高的建造成本，不满足经济性。这导致了企业在出厂前难以对提升钢丝绳的防滑性能进行准确测试。At present, due to the large number of manufacturers of friction pads, the manufacturing processes and production standards used are not the same, and the testing of pads lacks a unified device and standard. Due to the diverse geological conditions of the coal mine, different demands are placed on the lifting load and lifting speed, resulting in friction hoists with different drum and wire rope diameters, which in turn determines the rope groove of the friction pads mounted on the drum surface The radian and diameter, resulting in friction pads of different specifications, making it difficult to use a uniform device for the anti-skid performance test of the pad. If the test devices are built separately for different sizes of friction pads, it will generate higher construction costs and do not meet the economy. This makes it difficult for enterprises to accurately test the anti-skid performance of the steel wire rope before leaving the factory.
当前，针对对摩擦衬垫的测试检测研究，专利号为ZL 201410271323.4公开的摩擦衬垫-提升钢丝绳动态摩擦传动试验装置能够模拟钢丝绳动态耦合振动状态下摩擦衬垫与提升钢丝绳之间的动态摩擦传动特性；专利号为ZL 201510102984.9公开的提升机用钢丝绳、摩擦衬垫综合摩擦检测装置可以模拟缠绕式提升机钢丝绳与摩擦衬垫间的高速滑动摩擦行为；专利号为ZL 201410161230.6公开的提升机摩擦衬垫的微滑移试验平台可以实现实现变频率、变幅值、变载荷及变弧度微滑移摩擦试验；专利号为ZL 201410152097.8公开的监测钢丝绳-摩擦衬垫动态微摩擦状态的试验装置可以检测钢丝绳与摩擦衬垫接触弧不同区段的微滑移幅值和钢丝绳-摩擦衬垫之间的动态摩擦力；专利为ZL 201010567284.4公开的摩擦衬垫检测机利用压紧油缸对衬垫施加压力，依靠压力传感器检测滑动摩擦力，进而检测摩擦衬垫的摩擦系数；专利号为ZL 02212593.0公开的摩擦衬垫摩擦性能模拟试验机使用活塞式油缸实现钢丝绳张紧、移动并起导向作用，从而检测衬垫摩擦系数。上述研究主要存在以下问题：第一，对单一型号衬垫进行微动磨损、碰磨、滑磨等理论研究，不能够对不同绳槽弧度和直径的摩擦衬垫进行统一测试；第二，主要采用直线拉动钢丝绳与摩擦衬垫相对滑动来模拟实际提升 过程，而真实的摩擦衬垫的绳槽一般带有弧度，钢丝绳与摩擦衬垫是弧形接触，导致不能准确评估摩擦衬垫的磨损形态；第三，采用钢丝绳直线拉动的方式，受限于钢丝绳直径、最小卷筒直径、卷筒容绳量的限制，难以模拟持续高速滑动摩擦。因而，有必要研究一种防滑测试装置，可以对不同绳槽弧度和直径的摩擦衬垫进行静摩擦和动摩擦测试，特别是是钢丝绳高速滑动下的防滑测试，以便对各厂商生产的不同型号摩擦衬垫在现场安装前统一校核，规范摩擦衬垫市场，确保摩擦衬垫的防滑性能，对于保障摩擦提升安全性具有重要意义，而目前缺乏相应的测试装置。At present, for the testing and research of friction pads, the friction pad-lift wire rope dynamic friction transmission test device disclosed in patent number ZL201410271323.4 can simulate the dynamic friction transmission between the friction pad and the lift wire rope under the dynamic coupling vibration state of the wire rope Features; Patent No. ZL 201510102984.9 discloses an integrated friction detection device for hoist wire ropes and friction pads that can simulate high-speed sliding friction behavior between the winding hoist wire rope and friction pads; Patent No. ZL 201410161230.6 discloses hoist friction linings The micro-slip test platform of the pad can realize the micro-slip friction test with variable frequency, variable amplitude, variable load and variable arc; the patent number ZL201410152097.8 discloses a test device for monitoring the dynamic micro-friction state of the steel wire-friction pad can be detected The micro-slip amplitude in different sections of the contact arc between the steel wire rope and the friction pad and the dynamic friction force between the steel wire and the friction pad; the friction pad testing machine disclosed in the patent ZL201010567284.4 uses a compression cylinder to apply pressure to the pad, Rely on the pressure sensor to detect sliding friction Detecting the friction coefficient of the friction pad; Patent No. ZL 02212593.0 disclosed the use of friction pads frictional performance simulator piston cylinder rope tensioning implement, and move from the guide so as to detect the pad friction coefficient. The above research mainly has the following problems: first, theoretical research on single-type liners such as fretting wear, rubbing, and sliding wear, etc., and it is impossible to conduct uniform tests on friction liners with different rope groove curvatures and diameters; second, main A straight line is used to pull the steel wire rope and the friction pad to slide relative to simulate the actual lifting process, and the rope groove of the real friction pad generally has an arc, and the steel wire rope and the friction pad are in arc contact, resulting in the inability to accurately assess the wear form of the friction pad Thirdly, the straight-line pulling method of the wire rope is limited by the restrictions of the wire rope diameter, the minimum drum diameter, and the capacity of the drum, which makes it difficult to simulate continuous high-speed sliding friction. Therefore, it is necessary to study a non-slip test device, which can conduct static and dynamic friction tests on friction pads with different rope groove radii and diameters, especially the anti-slip test under high-speed sliding of steel ropes, in order to test different types of friction linings produced by various manufacturers The pads are uniformly checked before on-site installation, the friction pad market is regulated, and ensuring the anti-skid performance of the friction pad is of great significance for ensuring the safety of friction enhancement, and there is currently no corresponding test device.
