Description

Technical Field

[0001] The invention relates to the technical field of coal mine auxiliary equipment, in particular to a coal mine double-plate extrusion fixed anti-slip adjustable front exploration beam lifting ring. Background Art

[0002] After the underground excavation and rock breaking are completed, support and rock transportation work is required. However, temporary support of the roof is particularly important during support. The temporary support method commonly used in coal mines is the front exploration beam. The front exploration beam is a device for temporary support of underground excavation work in coal mines. Therefore, the demand for a coal mine double-plate extrusion fixed anti-slip adjustable front exploration beam lifting ring is increasing.

[0003] Most of the front exploration beam lifting rings currently on the market cannot effectively fix the front exploration beam. When the roof is uneven, the front exploration beam is easy to slide down. Some units use iron zippers to prevent sliding, but the operation is inconvenient and the effect is not good. Some front exploration beam lifting rings lack the structure to limit and fix the front exploration beam, resulting in poor actual fixing effect when the front exploration beam is placed. Therefore, in response to the above problems, a coal mine double-plate extrusion fixed anti-slip adjustable front exploration beam lifting ring is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a coal mine double-plate extrusion fixed anti-slip adjustable front exploration beam lifting ring to solve the problems raised in the above-mentioned background technology.

One end surface of the top plate is fixedly connected to the fixing frame, the outer side of the fixing frame is slidably connected to the support plate, and the outer side of the support plate is provided with a fixing nut.

[0007] Preferably, the number of the support plates is 2, and fixing nuts are provided on both sides of the support plates, a thread groove is provided on the outer side of the fixing frame, and the fixing nut is spirally connected to the fixing frame through the thread groove.

[0009] Preferably, the other end of the sliding rod is fixedly connected with a baffle.

[0010] Preferably, a regular hexagonal through hole is opened on the inner side of the fixing sleeve, and the size of the through hole on the inner side of the fixing sleeve is consistent with the size of the fixing nut.

[0011] Preferably, the outer side of the slip ring is spirally connected with a fixing screw.
