In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of chain transmission type carriage head cover, comprise compartment, it is characterized in that: the top end of both sides, compartment is respectively provided with a guide rail housing, roller set installing port on guide rail housing is outwards arranged along box width direction, the steel rope guide rail of tensioner is provided with in guide rail housing, multiple connecting arm is had along car length directional spreding, connecting arm is connected with steel rope guide rail by roller set, and the adjacent rollers group on same steel rope guide rail is connected by tensioning chain; Last roller set be positioned on same steel rope guide rail is connected with driving chain, the front and back end place being positioned at same guide rail housing is respectively equipped with drive sprocket and driven sprocket, drive sprocket and driven sprocket are fixed on compartment, the two ends of driving chain are connected with drive sprocket and driven sprocket respectively, and two drive sprockets are connected with actuating device by synchrodrive axle; Be provided with the multiple tarpaulin bars along car length directional spreding between two guide rail housings, tarpaulin bar is close to upper end, compartment, and the two ends of tarpaulin bar are connected with the connecting arm of both sides, compartment respectively, and tarpaulin bar is provided with soft tarpaulin.
Further limit technique scheme, described roller set comprises roller mount, and be provided with multiple bearing in the chamber of roller mount, bearing is connected with roller mount by bolt.Advantage: the 1. friction coefficient of bearing is less, and driving efficiency is high.2. because bearing-transmission efficiency is high, cal val is few, can reduce the consumption of lubricating oil, safeguards and comparatively saves trouble.
Further limit technique scheme, described connecting arm is made up of the bending plate of two overlap joints.Advantage: 1. connecting arm is convenient to the parts that handling, maintenance and removable parts damage, and productive costs is low.2. a liang bending plate is overlapped with and helps improve Joint strenght, thus ensure that stability and the service life of work.
Further limit technique scheme, described actuating device comprises hydraulic reservoir, oil pump, change-over valve and HM Hydraulic Motor, and hydraulic reservoir, oil pump form by change-over valve and HM Hydraulic Motor the oil circuit circulated.Adopt hydraulic-driven, by driving operation of oil pump after change speed gear box power taking, hydraulic control motor provides the propulsive effort of positive and reverse steering, and compare motor and drive, propulsive effort is larger, do not exist top cover flexible be hampered cause current overload phenomenon, greatly reduce system failure rate.
Beneficial effect: the 1. roller set installing port on guide rail housing is outwards arranged along box width direction, avoids the dregs in compartment to enter in guide rail housing like this, not easily produces long-pending soil, also prevent dregs unrestrained from both sides, compartment.2. roller set is wrapped in guide rail housing, and along rolling on steel rope guide rail, making tarpaulin bar have certain jerk value up and down, avoiding the problem that tarpaulin is stuck; Roller set in same guide rail housing is linked together by the steel-wire track of a tensioner, can prevent tarpaulin bar from producing like this and swing; Distortion adopt steel rope as guide rail, long service life, even if also can normally use.3. chain gear solves the skid tarpaulin left and right sides of causing of roller set and to stretch nonsynchronous problem, greatly reduce fault rate, simultaneously chain itself is if any damage, can direct worse broken parts, greatly reduce maintenance cost and maintenance time, improve operation benefits.4. tarpaulin bar is between two guide rail housings, and is close to upper end, compartment, can shield like this to the soft tarpaulin on tarpaulin bar, prevents the problem occurring soft tarpaulin scratch in travelling.5. the utility model have structure simple, be convenient to the advantage loading and unloading and safeguard, easy to use, productive costs is low, and can well prevent dregs from dishing out in compartment.
