The invention relates to a constant-traction-force vehicle-mounted traction device not prone to chain disengaging. A chain of an existing mining rolling chain type winch is prone to being blocked anddisengaged, therefore, the constant-traction-force vehicle-mounted traction device not prone to chain disengaging comprises a rotary motor, a first-stage reduction gearbox and a second-stage reductiongearbox, wherein the rotary motor, the first-stage reduction gearbox and the second-stage reduction gearbox are in connection transmission in sequence, an output main shaft of the second-stage reduction gearbox stretches out from one side and is provided with a double-body chain wheel, chain nests are arranged among every four adjacent teeth on the double-body chain wheel, the double-body chain wheel is provided with a circular ring chain, and the periphery of the double-body chain wheel is covered with a cylindrical chain box, one side of the cylindrical chain box is fixed to the side wall of the second-stage reduction gearbox, and two annular pressing plates are further arranged on the cylindrical chain box and are located on the two sides of a connecting ring respectively. The constant-traction-force vehicle-mounted traction device not prone to chain disengaging has the advantages of being scientific in design, not prone to chain disengaging, capable of performing traction force constant control and convenient to use and is suitable for being used in cooperation with various underground and aboveground mining tractors.
本发明涉及一种不易脱链的恒牵引力车载牵引装置。现有矿用卷链式绞车链条容易卡阻、容易脱出。为此,本不易脱链的恒牵引力车载牵引装置,包括回转马达、一级减速箱和二级减速箱,回转马达、一级减速箱和二级减速箱,三者顺次连接传动,二级减速箱的输出主轴从一侧伸出,其上设有双体链轮,所述双体链轮上每四个相邻齿之间均设有链窝,并配有圆环链条,且双体链轮周围罩有筒形链箱,该筒形链箱一侧固定在二级减速箱的侧壁上,筒形链箱上还设有两个环形压板,两个环形压板分居连接环两侧。本发明具有设计科学、不易脱链、牵引力可恒定控制、使用方便的优点,适合与各种井下、井上矿用牵引车配套使用。
