The brief introduction of BQGI-1 type portable multifunctional rail cutter bar

The quick treatments of the railroad rail’s fracture and the buck and all railroad accidents have puzzled the railroad public affairs department. With the development of the high speed high efficiency transportation. The traditional test technique is limited in apply, the railroad bureau cooperate with “Harbin ZhongHuanke Environmental Protection Equipments Co. Ltd.” to develop the BQGI-1 type portable multifunctional rail cutter bar. It possesses multiple functions. It is suitable for urgent repair on the work such as steel fracture, Swell to follow, Curved and so on. It is portable that only needs no more than two people to carry. (It depends on the railroad’s distance) save manpower, reduce the intensity of labor. It is easy to master. You can operate it after a bit of training. Safe to use. No worry about back draft. It takes about 10 minutes to cut four cross-sections and six screw holes. It can save much urgent repair time. The qualify standard of the cut-out surface can attain level Ⅱ, it accords with the demand of public affair department. This product adopts petrol-oxygen cutting principle and assists the special clamp apparatus, so that it can cut from perpendicular multiple angles. Especially for the urgent repair of the rail buck accident which any other equipment could not competent. The equipment has been placed on railroad department’s special tools.
    This equipment contains: two aluminum-alloy oxygen bottles(each of 10L One petrol storage tank One section cutting torch ；One circular hole cutting torch；One set of section frock clamp apparatus；One set of circular hole frock clamp apparatus 。
    The main performance feature of this equipment ：
    1. light 、small and portable.
    Its total weight is 30KG, overall dimensions are 700mm×150mm×150mm. gas cylinder and oil storage tank can either be carried on the back or by hand. It requires two people to walk to the accident scene rapidly. (Electric gearless torch equipment which has been used now weights about 300KG. oxygen- acetylene equipment weighs about 200KG. that is too inconvenient to carry.)
    2. Complete function, one serves several purposes.
    1. It can solve not only broken rail and the cutting off track in winter but also the buck of rail in summer. (At present, electric gearless torch can hardly solve the buck of rail in summer.)
    3. Fast cutting speed, high quality.
    The cutting speed reaches 300mm/min.Because of the protection of the frock clamp apparatus. Cutting quality attains level Ⅱof the flame cutting surface quality, sometimes even levelⅠ.
    4. Easy to operate, easy to master.
    This equipment adopts frock clamp apparatus which are specialized in cutting. It has simple structure and is easy to operate. It can be used by people of all levels after a bit of training.
    5. Low cost, low price.
    This equipment’s oxygen bottles and petrol storage tanks are all manufactured by the enterprise which the national labor security department has award the manufacturing license. It can meet the needs of safety in productions.
   Main technical parameters：
    1. The oxygen’s pressure: 0.6MPa.
    2. the petrol’s pressure: 0.2MPa
    3. cutting speed: 300mm/min
    4.cutting quality : level Ⅱ
    5. For cutting one section on average, the oxygen consumption is 0.56m3, oil consumption is 50g.
    6. For cutting one ф 31 holes on average, the oxygen consumption is 0.14m3; the oil consumption is 7.6g.
