Abstract

The utility model relates to a multiplex cage guide, which is improved and perfected by the patentee of the original multiplex cage guide (87207603.2) during implementation. Lining wood (1), a steel core (2), adhesive agent (3), an inner screw bolt (4) and a nylon buffer wear resisting layer (5) with oil are firmly compounded into a cage guide body of which the section is rectangular, and the cage guide body is fixed on a cage guide beam (7) by a rigid support seat (6). When the lifting speed of the multiplex cage guide is less than or equal to 10 meters / second, the multiplex cage guide can replace a steel cage guide, a wood cage guide and a steel rope cage guide, and the utility model not only can satisfy each requirement on design, but also has the advantages of good combination property, low cost, easy construction, low energy consumption and safety. The utility model is completely feasible for the various vertical shafts of mining industry.

Description

Composite cage guide

The utility model relates to the rail set of lifting container operation in a kind of be widely used in mining industry shaft hoisting system with composite structure.

When the shaft equipment that the design vertical shaft for mine promotes, by the well lane engineering design manual of metallurgy, chemical industry, coal, cage guide series that the design reference document is selected for use all are single materials, three kinds of steel guides, wooden cage guide, steel cable cage guide are arranged, this just makes and satisfy to promote under the condition of technology, because of the unicity of material causes following deficiency:

Steel guide: have and rollingly lead the shape steel guide and with two kinds of the combination cage guides of shaped steel weldering system, the then homemade at the scene welding shaped steel composite can roads that adopt of China more, distortion is big during this cage guide weldering system, be difficult for adjusting, reject rate can be up to 15～20%, and every meter heavily about 60 kilograms, the cost height; Because it can not realize disconnected rope braking on cage guide, so when adopting the single-rope hoisting machine to promote, must set up special-purpose braking steel cable and realize disconnected rope braking, thereby realizing glancing impact on cage guide, the cutting depth ratio that makes vertical shaft increases by 8～15 meters, the loading of lifting terminal increases more than 500 kilograms, energy consumption is big, for this reason sometimes even force design to have to bypass the immediate leadership and select relatively large gig for use, construction cost and energy consumption are further increased again; When the construction cost of its headframe promotes more than the single-rope hoisting machine again when adopting multi-rope hoist to promote the construction cost costliness of derrick many.

Wooden cage guide: the vertical shaft that adopts the wooden cage guide equipment, slotting pawl safety card on the lifting container can be realized disconnected rope braking on cage guide, but the material to Sawn timber for shaft lifting guide is strict, the relevant regulations of the China and the former Soviet Union in design manual, must make above 6 meters high-quality timber (Korean pine, oak, ashtree) of I, II level length, and the interlamellar spacing of buntons must not surpass 2.5 meters, and source China of this timber is very difficult at present; With the vertical shaft of 5.5 meters of hole diameter Φ, 300 meters of well depths, two-cage hoisting is that the consumption and the necessary reserve level of example, Sawn timber for shaft lifting guide log can reach more than 100 cubic meters, normal because of solving the source of goods of these timber, have to force design to use the steel guide more much higher instead again and equip vertical shaft than wooden cage guide cost.

Flexible cage guide: it is a kind of flexible cage guide, its flexibility make cage in vertical shaft operation and at the turnover car at ingate place all than the poor stability of aforementioned two kinds of rigid cage guides; In China's mining design, also once once adopted in the period of nineteen sixty-eight to 1980, because the accident rate height has not adopted for designing unit now.

Under the prior art condition, can be combined with each other different several materials according to technologic requirement fully, make it to form a firm composite structure, compound armour as tank, the various members that carbon fiber is compound etc. all are their physical and mechanical propertiess that made performance that each most chief of properties of materials coordinates.

Based on this purpose of this utility model is to provide a kind of material source convenient, and processing and fabricating, installation are changed all simple broad spectrum type Composite cage guide and replaced known steel guide, wooden cage guide and steel cable cage guide.

Be example still: (getting index in 1984) with 5.5 meters of Φ, 300 meters of well depths, two cage vertical shaft

Accompanying drawing 1 is the shaft section area of shaped steel combination cage guide (a) configuration, 4.168 meters of interbedded distances (6.252 meters), 307 tons of the total steel quantity consumptions of shaft equipment (265 tons), equipment 78.14 ten thousand yuan of budgetary estimates (71.83 ten thousand yuan);

Accompanying drawing 2 is shaft section areas of wooden cage guide (b) configuration, 2.5 meters of interbedded distances (code requirement≤2.5 meter), 175 tons of the total steel quantity consumptions of shaft equipment, large scale high-quality timber 115 cubic meters, 55.7 ten thousand yuan of equipment budgetary estimates;

Dispose above-mentioned vertical shaft with the steel cable cage guide, the equipment budgetary estimate is 60.8 ten thousand yuan;

Accompanying drawing 3 is shaft section areas of the utility model Composite cage guide (c) configuration, 5.00 meters of interbedded distances, 151 tons of the total steel quantity consumptions of shaft equipment, common pine 55 cubic meters (not needing reserve level), 600 kilograms of oil-containing nylons, 47.5 ten thousand yuan of equipment budgetary estimates.

The concrete structure of Composite cage guide is provided by following examples and accompanying drawing:

Accompanying drawing 4 accompanying drawings 5 are details and the service conditions according to the concrete device that the utility model proposes;

The feature of its concrete device is: it is the composite structure of rectangle that lining wood (1) becomes a section with steel core (2) by lining cement (3) and inner bolt (4) mortise, at this moment nailing on thickness in the front of this structure is that 3～5 millimeters oil-containing nylon layers (5) make its formation identical with the geometric configuration of original design cage guide (steel guide, wooden cage guide), is fixed on the buntons (7) with rigid mount (6).It is characterized in that: to be single-piece length greater than two lumps of wood of 2.5 meters be bumped in the groove of steel core (2) lining wood (1) forms and the identical cage guide body of wooden cage guide physical dimension, and providing disconnected rope to brake on the cage guide for the slotting pawl safety on the lifting container is stuck in; Nail is at the oil-containing nylon layer in cage guide front, cushioned not only that positive side force, the friction coefficient of lifting container in operational process is little, resistance to abrasion also is better than timber, the spark that has produced when also having avoided the direct swiping bump of cage shoe bottom surface and steel core (2) wing rafter and the excessive abrasion of eardrum; Steel core (2) is with the strong rolled section steel that connects, the skeletons of cage guide body such as steel clamping plate; Lining cement (3) and inner bolt (4) are at first to make two kinds of materials of steel wood combine closely into the essential means of cage guide body, and its material is that water-proof high-strength lining cement and grade of steel are greater than No. 5 steel M ₁₂To M ₁₆Bolt.

Cage guide with this composite construction has had both the characteristics of steel, wood, several materials of oil-containing nylon. No Only can fully satisfy the requirement of rigidity on the intensity on the structural design, its whole synthesis performance also is better than tradition Cage guide and former Composite cage guide (87207603.2) have widely adaptability, are used for metallurgy, coal and chemical industry In the vertical shaft in mine, replace steel guide, timber guide and steel rope guide and improve its Technological Economy effect with it Benefit is in full force and effect.
