Description
Technical field
Can the utility model relate to generation serious deformation such as supporting is used under the coal mine trapezoidal steel band, channel-section steel, need carry out and recycling make judgement it under the prerequisite that guarantees its mechanical performance, and carry out the mechanism that quick straightening is repaired, relate in particular to channel-section steel precision straightener.
Background technology
At present, the form that arranges of vertical is adopted in domestic some colliery, and the degree of depth surpasses km.This class colliery is dark facing to pit shaft undoubtedly, press difficulties such as big, that rock is soft, ground temperature is high, water yield is big because highland pressure effect, do steel band that supporting uses, channel-section steel etc. serious deformation can take place.Again because if the back production mining way is adopted in the colliery, multi-form distortion all takes place after returning and removing in the channel-section steel that the coal column side is used for supporting.Pile up like a mountain for a large amount of deformation steel bands that reclaim and channel-section steel etc., the channel-section steel of former recovery is all handled with scrap iron, cause very big waste of material, repairing effect is poor, efficient is low and the steel band, the channel-section steel that adopt artificial reparation deformation carry out, damaged the mechanical performance of channel-section steel simultaneously, can't meet the needs of production, therefore need the new prosthetic appliance of development.
The utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of channel-section steel precision straightener is provided, with fast a kind of, high accuracy to the minimum machinery of channel-section steel mechanical performance damage, can realize that the support material secondary after repairing that reclaims comes into operation, ensureing safety of coal mines and meeting these deformation steel bands of recycling, channel-section steel under the prerequisite of relevant regulations, reduce production cost.
Channel-section steel precision straightener described in the utility model includes gearbox, output shaft gear, Hooks coupling universal coupling, adjustment screw rod, hydraulic cylinder, driven pulley, driving wheel and transfer case.Gearbox connects output shaft gear outward, and output shaft gear connects Hooks coupling universal coupling, and Hooks coupling universal coupling is connected to transfer case.Be provided with driving wheel and driven pulley in the transfer case, be provided with hydraulic cylinder above the transfer case, be provided with the adjustment screw rod above the hydraulic cylinder.Be provided with two groups of pinch rollers in the transfer case, each group has four pinch rollers, and two-layer about two groups of pinch rollers are divided into, horizontally, wherein one group is driving wheel, and another group is driven pulley, and the effect of driving wheel is to drive channel-section steel to rotate.Hooks coupling universal coupling is connected to transfer case, when output shaft gear during in the rotational speed that gearbox is adjusted, namely drive connected two pinions, pinion and its meshed gears make the driving wheel of four downsides rotate, and drive channel-section steel and rotate under the effect of roller frictional force.Driven pulley is on the top of driving wheel, its effect is that channel-section steel is carried out straightening, by adjusting the adjustment screw rod of hydraulic cylinder on the driven pulley diaxon head bearing chamber, can adjust driven pulley up and down, regulate the adjustment screw rod according to the thickness of channel-section steel and the distortion situation of channel-section steel, reach the control to channel-section steel straightening effect.Motor utilizes two-direction switch control, can change turning to of motor by two-direction switch, thereby reaches the rotation direction that changes driving wheel, thereby suppresses repeatedly repeatedly being out of shape serious channel-section steel, reaches acceptance criteria.
Channel-section steel precision straightener described in the utility model, overall structure is simple, and is easy for operation, good stability, reliability height.Use channel-section steel precision straightener described in the utility model, with fast a kind of, high accuracy, to the minimum machinery of channel-section steel mechanical performance damage, can realize that the support material secondary after repairing that reclaims comes into operation, ensureing safety of coal mines and meeting these deformation steel bands of recycling, channel-section steel under the prerequisite of relevant regulations, reduce production cost.
