Description
Technical Field
The invention relates to a tool, in particular to a quick engine sling unbinding device based on a spring motion rod.
Background
The processes of transportation, assembly and debugging and the like of the engine are required to be carried out by using a crane before the engine is tested, the task amount of the assembly and debugging of the engine before the engine is tested is increased along with the increase of the engine test and the increase of the model size, some engines needing high-temperature or low-temperature tests are required to be tested within hours after being taken out of a warehouse, and the requirement on the assembly and debugging efficiency of the engine is continuously improved. Some large engines require testing within hours after leaving the heat-preservation workshop and finishing heat preservation, and the efficiency of the engine hoisting process determines the progress of the engine test.
Sometimes, when the engine is in a large size, the lifting hook is 5 meters away from the ground during hoisting, in order to avoid collision of the engine, the crane needs to move axially perpendicular to the engine, then the crane descends and unbinds the lifting belt, the moving speed of the crane is low, the working efficiency is greatly reduced due to the increase of the moving times, sometimes, 1h is needed for hoisting, and the improvement on high and low temperature tests and the working efficiency is not favorable.
At present, a hoisting link in the process of assembling and adjusting an engine adopts a crane, 4-5 workers cooperate with each other to put down a lifting hook of the crane and then take off a hanging strip. In the operation process, an operator is required to climb up the thrust trolley, so that the engine is easily collided and even safety accidents are easily caused, the whole process is required to be 1 hour or more, the heat-preservation engine cannot be ignited within the specified time, and the test effect is influenced.

Drawings
FIG. 1: a hook opening device;
FIG. 2: a sling adjusting device;
wherein: 1. the device comprises a first moving rod, a second moving rod, a baffle opening device, a hook fixing device, a connecting device, a spring, a third moving rod and a sling hook, wherein the first moving rod is 2, the second moving rod is 3, the baffle opening device is 4, the hook fixing device is 5, the connecting device is 6, the spring is 7, and the third moving rod is 8.
Detailed Description
The invention is further described in detail with reference to the accompanying drawings and specific embodiments:
the whole device is shown in figures 1 and 2, and the quick engine sling unbinding device based on the spring motion rod comprises:
the lifting hook opening device comprises a first moving rod, a second moving rod, a spring, a baffle opening device and a lifting hook fixing device, wherein the baffle opening device and the lifting hook fixing device are respectively fixed at the top ends of the first moving rod and the second moving rod, the positions of the baffle opening device and the lifting hook fixing device correspond to each other, the first moving rod and the second moving rod are connected in a crossing mode at 1/3, and the other positions of the first moving rod and the second moving rod 1/3 are fixedly connected through the spring;
the sling adjusting device comprises a third moving rod and a sling hook, and the top end of the moving rod is fixedly connected with the sling hook.
The baffle opening device is a concave iron block, one end of the concave iron block is contacted with the crane baffle, and the other end of the concave iron block is fixedly connected with the crane baffle; the two rods of the lifting hook opening device are connected through screws, and the lower ends of the two rods are fixedly connected with the spring; the hook fixing device is fixedly connected with the rod.
The sling adjusting device can be used for removing or installing the sling from the lifting hook. The sling hook is fixedly connected with the rod.
When the lifting is carried out, the lower end of the rod of the lifting hook opening device is manually pulled, the lifting hook fixing device and the baffle opening device are aligned to the lifting hook, then the lifting hook is opened under the action of the spring, and at the moment, the lifting belt is taken down or put on by the lifting belt hook.
The length of the motion rod is made of an aluminum alloy material with the length of more than 5 meters; selecting a spring with the spring tension of more than 100N and the elastic coefficient of more than 5N/cm; the baffle opening device and the lifting hook fixing device are externally attached to the rubber layer, and friction force is increased. The motion rod is made of aluminum alloy materials, so that the quality is reduced on the premise of ensuring the strength. The baffle opening device and the lifting hook fixing device are processed by rubber materials, so that the friction force between the baffle opening device and the lifting hook is increased, and the sliding is prevented.
The spring requires that the tension F is more than or equal to 100N, so that the lifting hook of the overhead travelling crane or the crane can be completely opened. The outside of the motion rod needs to be wrapped by a plastic film, so that the motion rod is prevented from being scratched or generating static electricity to cause safety accidents.
The bolt position is in two motion pole front ends 1/3 departments, and the spring dress can guarantee according to lever principle that spring tension equals with the pressure moment that the lifting hook received at two motion pole rear ends one-third department, therefore the lifting hook receives pressure and is spring tension to guarantee that the lifting hook is opened completely, when operating personnel pulling motion pole lower extreme in addition, moment is spring tension's 2 times, comparatively laborsaving.
As the modified design of the invention, the length of the motion rod can be adjusted, so that the invention can be suitable for engines with more models.
