Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Fig. 1 to Fig. 5 is please referred to, the present invention provides a kind of technical solution: a kind of wheel track trailer system of trailing suction hopper dredger, packet
Trolley 1 is included, trolley 1 itself uses DC motor drive, and the inside of trolley 1 is equipped with electromagnetic clutch device, convenient for driving certainly
Voluntarily switch under dragging two states, and the side of trolley 1 is connected with tractor 2, the top installation of tractor 2 by bolt
There is winch 3, self actuating system and the winch 3 of trolley 1 can work simultaneously, reduce trolley 1 or load when winch 3 works independently
The excessive probability for causing device to damage of lotus, the middle part of 3 side of winch are equipped with roll device 4, and roll device 4 includes outer cylinder 41, outside
Fixed device 42 is set in the middle part of 41 inner cavities of cylinder, fixed device 42 includes casing 421, and the side of 421 inner cavity of casing is set with
Five-way tube 422, casing 421 can convey hydraulic oil to four hydraulic stems 44 simultaneously, make the internal liquid pressure of four hydraulic stems 44
It is more uniform, prevent mandril 46 from tilting when going up and down, Five-way tube is socketed with petroleum pipeline 423, petroleum pipeline in the middle part of 422 side
423 be rubber hose, and the extended length of petroleum pipeline 423 is greater than the coasting distance of Five-way tube 422, effectively increases petroleum pipeline
423 drawing numbers and service life, Five-way tube 422 can be shunted according to the internal pressure of four hydraulic stems 44, effectively be mentioned
The high harmony of four 44 internal hydraulic pressures of hydraulic stem, the other side of petroleum pipeline 423 is set with rotary joint 424, rotary joint
424 are set with the middle part of 421 side of casing, and the two sides outside fixed device 42 are set with lasso 43, between two lassos 43
Equipped with hydraulic stem 44, and hydraulic stem 44 altogether there are four, the inlet of four 44 sides of hydraulic stem with the end of Five-way tube 422 into
Row connection, the top of lasso 43 are connected with connecting rod 45, and equidistant clamping is there are six connecting rod 45 respectively in the outside of two lassos 43, and two
The connecting rod 45 in 43 outside of lasso is often one group with respect to two, and the end of every group of connecting rod 45 is connected with mandril 46, mandril 46
Outside is equipped with the anti-skid chequer laterally arranged, and trip is skidded when can effectively avoid 41 winding steel wire of outer cylinder, 41 two sides rut of outer cylinder
