Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: the unhooking test device comprises a hook 1 with two ends respectively connected with a rope 9, wherein the hook 1 comprises a first hook body 101 and a second hook body 102 which are clamped with each other, a hanging hole 3 is respectively formed in one end, far away from the first hook body 101 and the second hook body 102, of the hook 1, the hook is conveniently connected with the rope 9 (or connected with connecting pieces such as buckles) through the hanging hole 3, the rope 9 at the two ends is a part bearing tensile force, clamping plates 4 are connected to two side faces of the hook 1, the first hook body 101 and the second hook body 102 cannot be separated in the transverse direction due to the installation of the clamping plates 4, accidental deviation and unhooking are prevented, clamping grooves 6 are formed in the two clamping plates 4, the unhooking test device further comprises a plug pin 7, two ends of the plug pin 7 are movably connected in the two clamping grooves 6, the plug pin 7 is inserted in the two clamping, the latch 7 is separated from the catching groove 6 only by pulling the latch 7 hard, and the latch 7 is not subjected to a tangential force and is stably coupled to the catching groove 6 at ordinary times, thereby preventing the separation between the first hook 101 and the second hook 102.

Specifically, be equipped with one at least on the bolt 7 and tear hole 8, connect the safety rope through tearing hole 8 and let the staff can remote operation, pull the safety rope and can pull out in the bolt 7 follow draw-in groove 6.

Specifically, as shown in fig. 2, a positioning plate 5 is rotatably connected between the two clamping plates 4 through a pin 10, the lower side surface of the positioning plate 5 is in close contact with the upper end of the hook 1 so that the positioning plate cannot rotate counterclockwise around the pin 10, and the upper side surface of the positioning plate 5 is in close contact with the lower side surface of the plug 7, so that the positioning plate 5 cannot rotate clockwise when the plug 7 is still located in the slot 6, and thus the two first hook bodies 101 and the second hook body 102 can be tightly pressed so that the two first hook bodies 101 and the second hook body 102 cannot be separated.

Specifically, in order to make the unhooking process more convenient and natural, the joint between the first hook 101 and the second hook 102 is provided with a wedge 11 and a wedge groove 12, and the inclined sides of the two wedges 7 and the force application direction of the rope 9 form an acute angle, so that after the bolt 7 is separated, the pulling force transmitted on the rope 9 acts on the contact surface between the wedge 11 and the wedge groove 12 (the force action schematic diagram is shown in fig. 4), and the first hook 101 and the second hook 102 can rotate relatively to separate from each other, thereby realizing the unhooking effect.

Specifically, a plurality of connecting holes 2 are formed in each of the clamp plate 4 and the second hook 102, and the two clamp plates 4 are connected to the hook 1 by bolts 13 penetrating the connecting holes 2, so that the clamp plates 4 and the hook 1 are in close contact with each other.

The working principle is as follows: when the hook is used, the first hook body 101 and the second hook body 102 are buckled together to form a complete hook 1, the two clamping plates 4 are clamped at two sides of the hook 1 and are fixedly connected through the bolts 13, the pin 10 and the positioning plate 5 are installed between the two clamping plates 4, then the bolt 7 is inserted into the clamping groove 6 formed in the clamping plates 4, after the work is completed, the top of the first hook body 101 is tightly attached to the positioning plate 5, the top of the left end of the positioning plate 5 is tightly attached to the bolt 7, so that the first hook body 101 and the second hook body 102 cannot be separated, the bolt 7 is connected with a safety rope, then the ropes 3 are respectively connected to the hanging holes 3 of the first hook body 101 and the second hook body 102, and the first hook body 101 and the second hook body 102 are respectively connected with a lifting hook (namely a tension source) and a detected device (such as a lifting cage and a mine car).

If the first hook body 101 and the second hook body 102 are separated, relative rotation is inevitably generated, but the upper side surface and the lower side surface of the positioning plate 5 are respectively blocked by the hook part 1 and the bolt 7, and are in a close contact state so that a component force in the horizontal direction is hardly generated, and therefore, a large pulling force can be borne between the first hook body 101 and the second hook body 102;

when a unhooking test needs to be carried out, the safety rope is pulled by force to pull the plug pin 7 out of the clamping groove 6, at the moment, the upper portion of the positioning plate 5 is not blocked, the stressed surface between the first hook body 101 and the second hook body 102 is the contact surface of the wedge block 11 and the wedge groove 12, as shown in fig. 4, a component force capable of rotating exists, the first hook body 101 and the second hook body 102 can deflect to be separated, and then the whole unhooking process is completed.

The utility model has the advantages of simple structure, low in processing cost, repeatedly usable to can make the unhook point keep away from operating personnel through the long-range pulling bolt 7 of safety rope, improve the security, and whole process can not produce spark and naked light, can adapt to fire prevention, explosion-proof sight.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
