Description

Technical Field

[0001] The utility model relates to the technical field of monorail hanging beam reinforcement, in particular to a monorail hanging beam reinforcement structure suitable for a top plate crushing zone. Background Art

[0002] Monorail beam reinforcement is to enhance the load-bearing capacity of the monorail beam body and improve its stability and reliability. With the increase of crane usage time and frequency, the monorail beam body may suffer from fatigue deformation, cracks and other problems, and cause the connected top plate to break, thus affecting the normal use of the crane. In order to solve these problems, it is necessary to use the monorail beam reinforcement with top plate breaking belt;

[0003] When a monorail is used to lift and transport a support in the underground, the work face for withdrawing the support is used. When anchor rods are used for lifting, the anchor rods are subjected to vertical tension, and the entire cross section of the anchor rods is stressed. When anchor cables are used for lifting, the exposed length of the anchor cables affects the operation of the monorail crane. When the anchor cables and the monorail beam body are vertically suspended, only anchor links can be used. Due to uneven force, the anchor cables are easily broken. There are safety risks when transporting hydraulic supports, and the top plate of the withdrawn work face is often relatively broken. When the monorail beam body is used to transport the support, due to the limitations of the support form in the original chute and the broken top plate, it is impossible to use anchor rods or I-beams to fix the monorail beam body. Therefore, the utility model proposes a monorail beam reinforcement structure suitable for a broken top plate zone to solve the problems existing in the prior art. Utility Model Content

The monorail hanging beam reinforcement structure suitable for a broken roof zone is provided with a center sealing plug, which passes through the through hole in the I-beam and is inserted into the drilled hole in the roof body. The outer cone surface is pressed against the hole wall of the drilled hole due to extrusion, which plays a role of radial sealing and fastening. An end face sealing plug is provided, which is pressed against the through hole wall in the I-beam, which plays a role of end face sealing and fastening.

At the same time, the I-beam is fixed to the bottom of the roof, and the force direction is changed by the anchor cable and the I-beam, which effectively ensures that the anchor cable is not easy to break. Bolts are provided to make the monorail hanging beam body connected to the support frame through the anchor chain and the connecting seat fixedly suspended at the bottom of the anchor cable, so as to avoid affecting the operation of the monorail crane locomotive due to the exposed length of the anchor cable when the anchor cable is lifted.
