Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

with reference to fig. 1 and 2, the single-rail hanging rail clamping groove resetting device comprises two U-shaped clamps 1, a base 2 and a telescopic mechanism 4, wherein the two U-shaped clamps 1 are arranged on the left side and the right side above the base 2 in parallel relatively. The U-shaped card 1 is made by bending a steel bar, and the opening of the U-shaped card 1 faces downwards. Two sides of the U-shaped card 1 are respectively provided with a limiting part 3, and the two limiting parts 3 are opposite in the positive direction and are integrated with the U-shaped card 1. The U-shaped card 1 is arranged on the outer side wall between the limiting part 3 and the end part of the U-shaped card and is provided with threads. Two ends of each U-shaped card 1 are respectively provided with a locking nut 4. The two U-shaped clamps 1 are respectively arranged on the two sections of track single bodies 6 and are positioned at one end of the joint of the two sections of track single bodies 6, and the base 2 is positioned right below the joint of the two sections of track single bodies. The two U-shaped clamps 1 are downward opened and respectively hung at the end parts of the two sections of track single bodies 6, and the lower ends of the U-shaped clamps 1 are detachably and fixedly connected with the base 2 through locking nuts 4.

The base 2 is a square plate made of metal, four corners of the base 2 are respectively provided with a mounting hole, and the four mounting holes are respectively matched with the end parts of the two U-shaped clamps 1 in a one-to-one correspondence manner. Two ends of each U-shaped card 1 penetrate through two corresponding mounting holes from the upper part of the base 2, and are screwed in the locking nuts 4 on the lower part of the base 2, the limiting parts 3 limit the relative movement of the base 2 and the U-shaped card 1, and after the locking nuts 7 are screwed on the U-shaped card 1, the limiting parts 3 are pressed on the upper surface of the base 2. The telescopic mechanism is arranged above the base 2 and located between the two U-shaped clamps 1, the movable end of the telescopic mechanism 4 is vertically upward, and a jack is preferably adopted by the telescopic mechanism 4. The middle part of base 2 upper surface is equipped with annular location portion 5, and the bottom of jack is located the inboard of annular location portion 5, and annular location portion 5 and base 2 structure as an organic whole.

The working process of the utility model is as follows: the underground monorail crane rail for the coal mine has the problems that a connecting clamping groove is not flexible in operation, the connecting position of two adjacent rail single bodies 6 has a wrong stubble with a high-low fall, the connecting positions of the two adjacent rail single bodies 6 are located on different horizontal lines, the operation of the monorail crane on the rail is influenced, one of the rail single bodies 6 needs to be reset, and the two rail single bodies 6 are located on the same horizontal line. Before the two U-shaped clamps are placed, the end part of one section of track single body 6 is in a normal state, the end part of the other section of track single body 6 is drooped, and the end part of one section of track single body 6 in a normal state is staggered. Two U-shaped clamps are respectively penetrated on the two sections of track single bodies through the outlet of the opening, the opening is downward and is respectively hung at one end of the joint of the two sections of track single bodies 6, and the lower ends of the two U-shaped clamps are respectively penetrated through the base 2 and are fixedly connected with the base 2 through the locking nut 7.

The jack is placed in the middle of base 2, and is located the inboard of annular location portion 5, and annular location portion 5 can restraint jack lateral motion relative to base 2. The jack is started, the end part of a piston rod of the jack starts to move upwards, the piston rod is firstly contacted with the drooping section of the track monomer 6 and drives the drooping section of the track monomer to move upwards together, when the piston rod of the jack drives the end part of the drooping section of the track monomer 6 to move to be in the same horizontal line with the end part of the normal section of the track monomer 6, the piston rod stops moving, and at the moment, the two U-shaped clamps 1 are in a tensioned state. After the track single body 6 after will restoring to the throne adopts stock or other modes to fix again, the piston rod return of jack, simultaneously, pull down four lock nut 7 that are located two U-shaped card tip, take off two U-shaped cards 1 from track single body 6, accomplish the restoration to track single body 6.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
