Abstract
The invention relates to a mining heavy type force unloading device which comprises a U-shaped connecting block (4), a bearing base (15) and a rotating body (7), wherein a hinge pin (10) is arranged at the opening end at the upper part of the U-shaped connecting block (4); a threaded hole (5) is arranged in the bottom of the U-shaped connecting block (4); a thread is arranged outside the bearing base (15) and connected with the threaded hole (5) in a matching manner; a bearing (6) is arranged in the bearing base (15); a screw rod (11) is arranged at one end of a stair shaft (of the rotating body (7)) which is connected with the bearing (6) in the matching manner; the screw rod (17) is connected with a screw nut (8) in the matching manner; the screw nut (8) is connected with a bearing press cover (12) in the matching manner; a U-shaped clamping groove (13) is arranged at the lower end of the rotating body (7); and a hinge pin (9) is arranged in the U-shaped clamping groove (13). By adopting the technical scheme, large and heavy equipment for mines can be stably and solidly hoisted, and the security is greatly improved.
Description
Technical field
The present invention relates to a kind of suspension hook hoisting device, particularly a kind of mining heavy type is unloaded power apparatus.
Background technology
In the mine construction process, need to be much large-scale, heavy mechanical equipment from the terrain transportation to the down-hole, but because of weight excessive, below in the process, steel rope produces rotation easily when being elongated, cause also and then together rotation of hoisting heavy, badly influences the safety of mine and the safety of down-hole miner, although midget plant can be sling with suspension hook, lift by crane much large-scale, heavy mechanical equipment and be still a difficult problem.
Summary of the invention
Purpose of the present invention is exactly that, heavy wares large-scale toward underground transportation in order to solve in the prior art produces the defective of rotation easily, provides a kind of mining heavy type to unload power apparatus.
The present invention seeks to be achieved by the following technical programs:
A kind of mining heavy type is unloaded power apparatus, it is characterized in that comprising:
A. U-shaped contiguous block, the upper, open end of U-shaped contiguous block is provided with pivot pin, the bottom is provided with tapped bore;
B. bearing seat, its outside is provided with screw thread and is connected cooperation with tapped bore, is provided with bearing in the bearing seat;
C. rotor, its stepped shaft are connected with bearing and cooperate an end to be provided with screw rod, and screw rod is connected cooperation with nut, and nut is connected cooperation with bearing gland, and the rotor lower end is provided with U-shaped draw-in groove, is provided with pivot pin in the U-shaped draw-in groove.
On the basis of above technical scheme, following further technical scheme can be arranged:
The pivot pin of described U-shaped contiguous block is provided with and protects becket bridle.
Owing to adopted technique scheme so that the present invention not only can be implemented in is large-scale to the mine lifting, steadily firm during heavy wares, but also the safety that greatly improves.
For more detailed explanation the present invention, following accompanying drawing provides a most preferred embodiment.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Shown in Fig. 1, Fig. 2, the invention provides a kind of mining suspension hook and unload power apparatus, mainly comprise a U-shaped contiguous block 4, the upper, open end of U-shaped contiguous block 4 is provided with pivot pin 10, pivot pin 10 is provided with and protects becket bridle 3, protect becket bridle 3 and be connected with steel rope 1, rope locking machine 2 plays fastening steel wire rope 1, and the bottom of U-shaped contiguous block 4 is provided with tapped bore 5; Tapped bore 5 is connected with the threaded bearing seat 15 of external belt, U-shaped contiguous block two bottom sides is equipped with jackscrew 16, jackscrew 16 is connected cooperation with bearing seat 15, and bearing 6 is installed in the bearing seat 15, and bearing gland 12 is installed on the bearing 6, bearing 6 and rotor 7 are connected cooperation with an end of stepped shaft, rotor 7 stepped shaft one end is provided with screw rod 11, and screw rod 11 is connected cooperation with nut 8, nut 8 and bearing gland 12 force fit, rotor 7 lower ends are provided with U-shaped draw-in groove 13, are provided with pivot pin 9 in the U-shaped draw-in groove 13.
Present embodiment has following two kinds of models, and is as shown in the table:
Design parameters:
Principle of work: when lifting weight is hung on the bearing pin of the U-shaped draw-in groove in rotor lower end, after weight is lifted, transfer by certain speed, steel rope stretches out gradually, lengthens.The steel rope that lengthens extends under the effect of weight, rotating wire rope is elongated, begin to produce rotation internal force, generate radially couple, rotation when the lower end steel rope is opened is because the surface bearing resistance is very little, slide during stressed opening this moment, so that swivel is along with wire rope rotating, thereby realize the power of unloading, reached the purpose that weight is transferred safely.
