Description

新型多功能省力拉马New multi-functional labor-saving Rama 技术领域Technical field
本发明涉及一种拉马，尤其涉及一种新型多功能省力拉马。The invention relates to a puller, in particular to a novel multifunctional labor-saving puller.
背景技术Background technique
拉爪顶拔器又称“拉马”，是机械维修中经常使用的工具。主要用来将损坏的轴承、皮带轮、齿轮等从轴上沿轴向拆卸下来。目前市面上的拉马主要分为机械拉马和液压拉马两种，一般直径小，所需拉力小的工件用机械拉马就可以了，使用时，将螺杆顶尖定位于轴端顶尖孔调整拉爪位置，使拉爪挂钩于轴承外环，旋转旋柄使拉爪带动轴承沿轴向向外移动拆除。如果工件拆卸时所需拉力较大，则采用液压拉马，液压拉马是以油压起动杆直接前进移动，故推动杆本身不做转动。钩爪座可随螺纹直接做前进后退之调距，操作时只要把手前后小幅度摆动，油压起动杆前移，钩爪相对应后退，将被拉物体拉出。The claw puller, also known as the "Lama", is a tool often used in mechanical maintenance. Mainly used to remove damaged bearings, pulleys, gears, etc. from the shaft in the axial direction. At present, the Rama on the market is mainly divided into mechanical puller and hydraulic puller. Generally, the diameter of the workpiece is small, and the workpiece with small pulling force can be mechanically pulled. When using, the tip of the screw is positioned at the top end of the shaft. The position of the claw is such that the pulling claw is hooked to the outer ring of the bearing, and the rotating handle causes the pulling claw to drive the bearing to move outward in the axial direction to be removed. If the pulling force required for the workpiece is disassembled is large, the hydraulic puller is used, and the hydraulic puller is directly moved forward by the hydraulic starting lever, so the push rod itself does not rotate. The hook claw seat can directly make the forward and backward adjustment distance with the thread. When the operation is small, the handle is moved forward and backward, the hydraulic pressure start lever is moved forward, and the hook claw is correspondingly retracted, and the pulled object is pulled out.
现有的液压拉马不仅体积大、使用笨重，并且可承受的最大拉力都有吨位限制，一旦使用时液压拉马承受的拉力超过了其设定的最大值时，将会发生漏油，造成损坏，大大缩短了其使用寿命，若没有及时发现漏油现象，那么该操作过程将非常危险。而现实使用中，人们往往无法测量或预知所需拉拔工件的吨位值，操作过程中，一旦液压拉马所承受的拉力大于其可承受的最大吨位，则必将造成该液压拉马的损坏，大大提高了维修成本。The existing hydraulic puller is not only bulky, cumbersome to use, but also has a tonnage limit for the maximum tensile force that can be withstood. If the tensile force of the hydraulic puller exceeds its set maximum value when used, oil leakage will occur, resulting in oil leakage. Damage is greatly shortened, and if the oil leakage is not detected in time, the operation will be very dangerous. In reality, people often cannot measure or predict the tonnage value of the workpiece to be pulled. During the operation, once the hydraulic puller is subjected to a tensile force greater than the maximum tonnage that it can withstand, the hydraulic puller will be damaged. , greatly improving the maintenance cost.
现有技术中无论是机械拉马还是液压拉马都存在省力与高效工作相矛盾的状况，大多数被拉工件在被拉过程中，往往是拉马启动的那一时刻需要最大力矩，一旦拉马拉动被拉组件发生移动后，拉马将不在需要较大力矩即可将被拉工件拉出，但现有的机械拉马和液压拉马工作时的 力矩均恒定的无法根据需要调节，即，在操作拉马功率不变的情况下，拉马拉动被拉工件的移动速度不会发生改变，上述拉马至少其存在两个弊端，1、是力矩较小无法启动工作；2、是力矩较大，可以启动工作，但工作效率极低。因此目前急需一种力矩和工作效率可调的拉马，改变现在拉马市场的现状。In the prior art, both the mechanical puller and the hydraulic puller have contradictory conditions of labor-saving and high-efficiency work. Most of the workpieces being pulled are in the process of being pulled, often the moment when the puller is started, the maximum torque is required. After the horse-drawn moving parts are moved, the puller will not pull the workpiece out if a large torque is required, but the existing mechanical puller and hydraulic puller work. The torque is constant and cannot be adjusted as needed. That is, the moving speed of the workpiece pulled by the Rama will not change when the operating pull power is constant. The above-mentioned puller has at least two drawbacks, 1. Smaller can not start work; 2, the torque is large, can start work, but the work efficiency is very low. Therefore, there is an urgent need for a puller with adjustable torque and working efficiency to change the current status of the Rama market.
