Description

Extensible bi-directional conveyer-belt conveyer

The utility model relates to a kind of transportation device that is exclusively used in underground condition, is widely used in the transportation of coal mine downhole crossheading driving back coal, spoil and supplies.

Present domestic existing SS-44, SJ-80A, the two-way transportation ribbon conveyer of SJ-80B type, last belt is outwards transported coal, and following belt inwardly transports supplies.Its material ship of earlier material being packed into promotes the material ship and enters down in the belt grooves, is controlled by striker plate and transports driving surface to belt.This transportation mode needs to set up the restriction that device ， And such as filling place, feeding rack are subjected to supporting leg in transport plane one side, can not transport such as materials such as arched roof and transport plane self parts.These supplies that surpass belt width are also had to by a dead lift, and labour intensity is big, perhaps use equipment transportations such as monorail crane or winch relay, and these accessory equipment expenses Gao ， And has certain technical requirements to roadway support.

Task of the present utility model provides a kind of two-way transportation ribbon conveyer that belt transports supplies, following belt fortune coal of going up.The material that send is not subjected to the restriction of belt width and supporting leg, has solved the difficulty that the two-way conveyor of other type can not transport arch support, arched beam and transport plane self parts.

Task of the present utility model is finished as follows: on the basis of existing two-way ribbon conveyer, actuating device, band storing wheel, belt, discharging portion and drive end unit have been kept, set up double-plough type coal unloading device, charging portion, adjustable middle frame and reprinted dolly, its service direction is opposite with existing two-way conveyor, promptly goes up belt in the lane, down belt moves outside the lane.Start transport plane, coal enters the reprinting dolly from driving face through development machine, elevating conveyor, constantly pass to down on the belt by the plough formula in the dolly of the reprinting plate of unloading coal, when the following belt that moves outside the tunnel from driving surface is delivered to desired location with coal, this ground is provided with coal unloading device coal is unloaded to another belt or coal logical sequence, finishes the task to the outward transport coal.When needs when the crossheading mouth transports various supplies to driving surface, only material need be placed on and push belt in the charging portion to, material runs to discharging portion with last belt toward driving surface, rely on the force of inertia of material to unload automatically, reach the purpose of inwardly transporting supplies through tilting discharging carrying roller.Common used middle frame altitude hold.The utility model adopts the adjustable middle frame of sleeve-type supporting leg, and adjustment amount is 300～400 millimeters, and longeron is being adorned plain-barreled roll on it, longeron is installed the flute profile roller down.

The utility model is at coal mine downhole crossheading and development machine or coal loader is supporting when doing the transportation of coal road driving, and transportation lengths is extended with the continuous propelling of coal road driving face, integrates main transportation, assistant conveyance.Compare with the two-way conveyor of following belt haul, saved cost of equipment and shared lane spaces thereof such as side filling place, feeding rack and material ship, particularly solved the transportation problem of U-shaped steel arch support, arched beam and transport plane self parts.Adjustable for height middle frame can keep the level run of belt in the little tunnel that rises and falls.The utility model seldom takies drift section, accelerates driving speed, and has solved the problem of a dead lift supplies at all, has greatly alleviated labour intensity, has saved manpower and equipment investment.
