Description

Self-unloading snap ring for hoisting

technical field

The utility model relates to the improvement of tools and equipment used in the field of installation and hoisting, in particular to a self-unloading snap ring for hoisting and hoisting.

Background technique

Hoisting construction is a routine work in the installation of chemical buildings. There are various hoisting tools involved, and the snap ring is the most commonly used small tool in the hoisting tools. All kinds of snap rings in the past need to be disassembled manually after hoisting. Most of the construction personnel do not have the conditions to disassemble the snap rings. Therefore, construction personnel are often required to do a lot of auxiliary work, such as erecting temporary scaffolding, which is laborious and laborious. , wasting the number of mechanical shifts used, resulting in a lot of cost waste.

Contents of the invention

The purpose of this utility model is to provide a self-unloading snap ring for hoisting with simple structure, low cost and convenient use in view of the above-mentioned shortcomings.

The technical scheme that realizes the utility model purpose is:

This kind of self-unloading snap ring for hoisting is composed of a U-shaped snap ring main body, and is characterized in that snap holes are respectively provided at the opening ends of the U-shaped snap ring main body, and a spring tube is fixedly connected to the outside of one of the snap holes. , a pin with a positioning round table is movably connected in the spring tube, and one end of the pin passes through the two clamping holes at the opening end of the main body of the U-shaped snap ring, and is connected with the two clamping holes in movable contact; the other end of the pin passes through the The end of the spring tube is in movable contact with the outlet of the spring tube, and the end of the pin is fixedly connected with a tail ring; a spring is arranged between the positioning round table of the pin in the spring tube and the outlet of the spring tube.

The utility model has a simple structure, and the existing metal materials and common parts can be selected, and the conventional technology is used for processing and manufacturing, so it is easy to implement.

The utility model can be made into different specifications and models according to the weight of the object to be hoisted, and is suitable for various occasions in installation, hoisting and construction, and has a very wide application range. The utility model has the advantages of simple structure, low cost, convenient operation, safety and reliability, saving a lot of manpower, material resources and mechanical shifts, wide application range, etc., and has popularization value.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

In the figure: 1. U-shaped clasp main body, 2. circular clamping hole, 3. spring tube, 4. pin, 5. positioning round table, 6. spring tube outlet, 7. tail ring, 8. spring.

Detailed ways

Below in conjunction with accompanying drawing and given embodiment the utility model is further described.

Referring to Fig. 1, this kind of self-unloading snap ring for hoisting is composed of a U-shaped snap ring main body 1, and circular snap holes 2 are respectively arranged at the opening ends of the U-shaped snap ring main body. A spring tube 3 is fixedly connected, and a cylindrical pin 4 with a positioning round table 5 is movably connected in the spring tube. The left end of the pin passes through the two clamping holes at the opening end of the main body of the U-shaped snap ring, and moves with the two clamping holes. contact connection. The right end of the pin passes through the end of the spring tube and is in movable contact with the outlet 6 of the spring tube, and the end of the pin is fixedly connected with a tail ring 7 . A spring 8 is arranged between the positioning round platform of the pin in the spring tube and the outlet of the spring tube.

During hoisting use, a rope can be tied inside the pin tail ring. When hoisting, pull the rope in the tail ring of the pin, and the pin moves to the right, so that the main body of the U-shaped snap ring is in an open state, and the hoisting objects and wire ropes can be hung in the same way as the ordinary snap ring. After the hoisting object and wire rope are released, the rope that pulls the pin is released, and the pin returns to its original position under the action of the spring to lock the self-unloading snap ring. After the hoisting object is installed in place, the self-unloading snap ring can be separated from the hoisting object only by pulling the rope in the tail ring of the pin.

According to the embodiment, the applicant of the utility model implements the self-unloading snap ring for hoisting and hoisting. It is shown through trial under many internal operating conditions that it is very convenient and quick to use, safe and reliable, has a wide range of applications, and saves a lot of manpower and material resources. And mechanical shift, saving costs, welcomed by the trial.
