Description
Technical field
The utility model relates to machinery production technical field, especially relates to a kind of hoisting tool special.
Background technology
The loaded switch of existing main transformer is very heavy, cannot change only according to manpower, therefore whenever run into need to carry out loaded switch pendant-core examination, change loaded switch or main transformer overhaul time, just need crane to lift, not only consuming time but also there is danger.Because crane operator cannot see main transformer apical events clearly, can only be operated by the mode of artificial oral commander, this has very large potential safety hazard to main transformer sleeve pipe and staff.On the other hand, nowadays indoor transformer progressively increases, and when carrying out above-mentioned work to it, crane cannot play a role at all, and sometimes even need substation's exterior wall to knock open, difficulty of construction and complexity are very large.
Utility model content
For overcoming the problems referred to above, the utility model adopts following technical scheme:
A kind of hoisting tool special, comprise suspension ring and spacing orienting sleeve, described suspension ring are connected with guide rod, and the back of described guide rod is not provided with claw near suspension ring place, the top cover limited location orienting sleeve of claw.
The lower end of described guide rod is frustum.
Described claw is trapezoidal.
The utility model has the advantages that: this hoisting tool special is convenient, fast, safety in actual applications, and effect is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of hoisting tool special, comprises suspension ring 1 and spacing orienting sleeve 2, and described suspension ring 1 are connected with guide rod 3, and the back of described guide rod 3 is not provided with claw 4 near suspension ring 1 place, the top cover limited location orienting sleeve 2 of claw 4.
The lower end of described guide rod 3 is frustum.
Described claw 4 is in trapezoidal.
Principle of work is as follows:
During lifting, spacing orienting sleeve 2 and claw 4 are along guide rod 3 upward sliding, guide rod 3 lower end frustum reduces gradually to claw 4 support angle, claw 4 effectively lifts reduced diameter, claw 4 is placed in stepped hole, portable guide rod 3, unclamps spacing orienting sleeve 2, and spacing orienting sleeve 2 and claw 4 glide, claw 2 effectively adjusts dress diameter to become large, and claw 2 step can realize lifting after being finally stuck in mold center's rising head stepped locations.
