Abstract

The utility model relates to a composite cage guide, which is used for the shaft equipment used in a mining shaft hoisting system, and particularly when a single rope hoisting machine is used, the rope breaking braking device of a hoisting container is a cage guide which is braked by clawing a safety jaw to clamp tightly the cage guide body. The utility model is a high performance and wood-and-steel composite cage guide which is composed of lining wood and a steel core which are tightly combined by high intensity adhesive agent and inner screw bolts. The utility model is mainly used for replacing the existing wooden cage guide to solve the problem of the source of large-size high-grade cage guide wood materials and to improve the mechanical property of the wooden cage guide in order to enlarge the interlamellar spacing of the cage guide beam and reduce the cost of the shaft equipment.

Description

Composite cage guide

The utility model relates to a kind of composite construction that has, and is used for the rigid track device of mining industry shaft hoisting system hoisting container operation.

When the shaft equipment that the design vertical shaft for mine promotes, by the rigid cage guide series that metallurgy, chemical industry, coal and other relevant well lane engineering design manual, design reference document are selected for use, all are single materials, two kinds of steel guide, timber guides are arranged.This just makes and satisfy to promote under the condition of technology, because of the unicity of material has caused following deficiency.

Steel guide comprises two kinds of profile iron cage guide and shaped steel combination cage guides.China still now more adopts homemade shaped steel to make up cage guide, and this cage guide is out of shape when welding processing greatly, is difficult for levelling, and percent defective can be up to 15～20%, and every meter weight reaches 60 kilograms, the cost height.Because they all can not realize disconnected rope braking on cage guide,, realize its disconnected rope braking with the steel cable safety card so when adopting the single-rope hoisting machine to promote, just must set up the braking steel cable.Thereby the cutting depth ratio that makes vertical shaft increases by 8～15 meters when using timber guide, and the terminal loading that promotes steel cable increases more than 500 kilograms, and energy consumption increases.For this reason, sometimes even force design to bypass the immediate leadership and select relatively large elevator for use, construction cost is further increased.

Again because of the cost of single-rope hoisting machine and derrick than the low cost of multi-rope hoist and headframe many, can reach 20%, this just makes the single-rope hoisting system under the situation that adopts timber guide, still has bigger market.

Timber guide, the vertical shaft that adopts timber guide to equip, the slotting pawl safety card on the hoisting container can be realized its disconnected rope braking on cage guide.But the material to Sawn timber for shaft lifting guide is strict, by the pertinent regulations of the China and the Soviet Union, need to make of I, II level large scale high-quality timber (oak, Manchurian ash, Korean pine), and the timber of this specification source is very difficult at present in China.With 5.5 meters of hole diameter φ, 300 meters of well depths, the vertical shaft of two-cage hoisting are example, and the consumption of Sawn timber for shaft lifting guide log and reserve level can reach more than 100 cubic metres.Normal because of solving the source of this batch high-quality timber, make design have to again to use instead than the timber guide costliness the steel guide of Duoing is equipped vertical shaft.

Under the prior art condition, can be combined with each other the material of unlike material fully, form a firm composite construction, as composite armour of tank etc., make each most chief of material bring into play physical and mechanical properties simultaneously.Based on this, the purpose of this utility model is to provide a kind of material source convenient, is easy to processing and fabricating, all simple Composite cage guide of replacing is installed is replaced known timber guide.

Since the steel of Composite cage guide, wooden composite construction on strength and stiffness greater than timber guide, be not more than by the hoisting velocity of single-rope hoisting machine in the limit of 12 meter per seconds and design, can the interlamellar spacing of timber guide girder steel from standing order≤2.5 bring up to≤4.5 meters, the pit shaft construction cost is further descended.

Still with 5.5 meters of φ, 300 meters two cage vertical shafts of well depth are example;

Fig. 1 is the shaft section area of shaped steel combination cage guide configuration, 4.168 meters (6.252) rice of interbedded distance, 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).

Fig. 2 is the shaft section area of timber guide configuration, 2.5 meters of interbedded distances, and 175 tons of the total steel quantity consumptions of shaft equipment, the high quality and large size Korean pine comprises 115 cubic metres of essential reserve levels, 55.7 ten thousand yuan of equipment budgetary estimates.

Fig. 3 is the shaft section area of the utility model configuration, 4.00 meters of interbedded distances, 168 tons of the total steel quantity consumptions of shaft equipment, 55 cubic metres in Korean pine, 43.54 ten thousand yuan of equipment budgetary estimates.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 4, Fig. 5 are section and the sectional drawings according to the Composite cage guide that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 4, Fig. 5 according to the concrete device that the utility model proposes.

Lining wood (1) and steel core (2) pass through bonding agent (3) and inner bolt (4), the firm composite construction that to be combined into a section be rectangle, and the geometry of it and timber guide is identical.It is characterized in that, lining wood (1) is single-piece length greater than two lumps of wood of 2.5 meters, be bumped into the body that forms in the groove of steel core (2) with the identical Composite cage guide of timber guide physical dimension, and provide disconnected rope braking for the slotting pawl safety chucking card cage guide on the hoisting container.Steel core (2) is with the strong rolled section steel that connect such as steel clamping plate, the skeleton of composite construction.Bonding agent (3) and inner bolt (4) are to make steel, two kinds of essential means that material is combined closely of wood, and its material is water-proof high-strength bonding agent and the grade of steel bolt greater than No. 5 steel M12 to M16.

Cage guide with this composite construction has had both the characteristics of steel, wood two kinds of materials, and on the bulk strength of structure greater than 2.1 times of timber guide, on the rigidity greater than 1.14 times of timber guide Y-axis, 3.4 times of X-axis.Therefore, it is in full force and effect replacing timber guide and improve its technical economic benefit with it.

Claims

1, ascending/decending level gauge is characterized in that adopting a device that makes vertical pivot directly rise or to descend, and this device is made up of a spiral handwheel (4) and push rod (5).
