Technical Field

The invention relates to a support for a coal mine, in particular to a novel hoisting structure of a unit support.

Background

The pressure of the fully mechanized mining face machine lane and the air lane affected by mining within a range of 20-30 m from the working face is large, and in recent years, a unit type advance support (in the application, referred to as a unit support) shown in fig. 1 is mostly adopted in the range. The unit support has the characteristics of simplicity, portability and no repeated support.

The monorail crane shown in fig. 2 is mostly adopted for transporting the unit support in the roadway, and the unit support is lifted by using a lifting hook of the monorail crane and transported from the tail end to the front end of the working surface.

In the transportation process of the unit support matched with the monorail crane, if the hoisting mechanism is not suitable, instability in the transportation process is easy to occur. Therefore, the position and the structural form of the unit support hoisting mechanism are important factors influencing the use of the unit support.

The first prior art is as follows:

as shown in fig. 3, the unit support is hoisted by means of the hoisting beam, the hoisting beam is connected with the hoisting rings on the base of the unit support, and hoisting and transportation are realized by using front and rear monorail crane trolleys.

The first prior art has the following defects:

the front and the rear travelling trolleys are occupied, and the lifting beams are adopted for lifting, so that the structure is complex; the hoisting point is arranged in the middle of the bracket, and the instability is easy to occur in the transportation process.

The second prior art is:

as shown in figure 4, the unit support is hoisted by means of the hoisting hole on the base, the unit support is directly connected and hoisted with the hoisting ring on the base by using the hoisting hook, and the single monorail crane trolley can be moved.

The second prior art has the following defects:

the hoisting point is arranged in the middle of the bracket, and the instability is easy to occur in the transportation process.

In view of the above, the present invention is particularly proposed.

Detailed Description

The technical scheme in the embodiment of the invention is clearly and completely described below by combining the attached drawings in the embodiment of the invention; it is to be understood that the described embodiments are merely exemplary of the invention, and are not intended to limit the invention to the particular forms disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

The terms that may be used herein are first described as follows:

the term "and/or" means that either or both can be achieved, for example, X and/or Y means that both cases include "X" or "Y" as well as three cases including "X and Y".

The terms "comprising," "including," "containing," "having," or other similar terms of meaning should be construed as non-exclusive inclusions. For example: including a feature (e.g., material, component, ingredient, carrier, formulation, material, dimension, part, component, mechanism, device, process, procedure, method, reaction condition, processing condition, parameter, algorithm, signal, data, product, or article of manufacture), is to be construed as including not only the particular feature explicitly listed but also other features not explicitly listed as such which are known in the art.

The term "consisting of … …" is meant to exclude any technical feature elements not explicitly listed. If used in a claim, the term shall render the claim closed except for the inclusion of the technical features that are expressly listed except for the conventional impurities associated therewith. If the term occurs in only one clause of the claims, it is defined only to the elements explicitly recited in that clause, and elements recited in other clauses are not excluded from the overall claims.

The term "parts by mass" is intended to indicate a mass ratio relationship between a plurality of components, for example: if X component is X parts by mass and Y component is Y parts by mass, the mass ratio of the X component to the Y component is X: Y; 1 part by mass may represent any mass, for example: 1 part by mass may be expressed as 1kg or 3.1415926 kg. The sum of the parts by mass of all the components is not necessarily 100 parts, and may be more than 100 parts, less than 100 parts, or equal to 100 parts. Parts, ratios and percentages described herein are by mass unless otherwise indicated.

Unless expressly stated or limited otherwise, the terms "mounted," "connected," and "secured," etc., are to be construed broadly, as for example: can be fixedly connected, can also be detachably connected or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms herein can be understood by those of ordinary skill in the art as appropriate.

When concentrations, temperatures, pressures, dimensions, or other parameters are expressed as ranges of values, the ranges are to be understood as specifically disclosing all ranges formed from any pair of upper, lower, and preferred values within the range, regardless of whether ranges are explicitly recited; for example, if a numerical range of "2 ~ 8" is recited, then the numerical range should be interpreted to include ranges of "2 ~ 7", "2 ~ 6", "5 ~ 7", "3 ~ 4 and 6 ~ 7", "3 ~ 5 and 7", "2 and 5 ~ 7", and the like.
