1.问题的提出 目前,大件重物的吊装搬运,通常是用钢丝绳来完成的。钢丝绳绳头处的套可以用金属套管压合而成,而最多的是用插编方法,把绳头和绳体编织在一起。 在钢丝绳套插编过程中(见图1),插套机的插针带着绳头的一股由液压缸推动,插入绳体中。在插入时,纫绳口处的尖角经常挂丝,严重影响了插编的速度和质量。因此,必须将插针进行改进。 2.插针的改进 产生挂丝的原因,是因为插针在向钢丝绳体中强行插入时,钢丝绳体对插针有一个很大的压力,当纫口经过钢丝绳体向下插入时,绳体就会进入纫口,纫口的尖角就会挂丝。目前是通过旋转液压缸杆和绳套,使纫口的尖角对准插针插开的缝隙,即使是非常熟练的工人,也常常因为把握不好旋转的角度而挂丝。 为了解决这一难题,我们设计了一个活动纫口。在通常情况下,由于重力的作用,活动纫口的舌体向外张开,以便于纫绳。当把绳股纫进纫口之后,纫入的绳股
1. Proposed Issues At present, the hoisting and handling of large heavy objects is usually done by wire ropes. Wire rope rope at the sleeve can be made of metal casing pressed together, and most is the use of interpolation method, the rope and the rope weave together. In the rope socketing process (see Figure 1), the needle inserted into the machine with a rope thrown by the hydraulic cylinder, inserted into the rope. When inserted, the sharp corners of the rope loop often hanging wire, seriously affecting the speed and quality of the plug. Therefore, the pins must be improved. 2. Pin to improve the reasons for the hanging wire, because the pin is forced into the wire rope body, the wire rope on the pin has a lot of pressure, when the wire rope inserted through the lower body when the rope body Will enter the mouth, the sharp edges of the mouth will hang wire. At present, by rotating the hydraulic cylinder rod and the rope cover, the sharp corners of the sewing mouth are aligned with the gaps where the pins are inserted. Even highly skilled workers often hang the wire because of their misunderstanding of rotation. In order to solve this problem, we designed a movable mouth. Under normal circumstances, due to the action of gravity, the mouth of the movable opening flares to facilitate the reeling of the rope. When the rope into the sewing trunks, the rope into the rope
