Abstract
The utility model discloses a power hydraulic pipe draught device for semitrailer comprising a hydraulic pipe, wherein two sides of the hydraulic pipe are respectively connected with a tractor head and a semitrailer body, a certain degree of bend and extended length are preset. The tractor head or the semitrailer body is mounted with a pulley block above the hydraulic pipe, while one end of a drawing line on the pulley block is connected with a weight and another end is suspended with a power hydraulic pipe draught device of hydrualic pipe semitrailer, the hydraulic pipe is suspened via the pulley block and the weight, to impact vehicle in normal driving of vehicle. And since the hydraulic pipe has a preset bended and extended length, when in steering, the pulley block and weight can be adjusted relatively to bend or extend the hydraulic tube, in order to avoid being damaged by overload.
Description
Technical field
The utility model relates to a kind of device of automobile.Especially a kind of device that on superimposed trailer, is used for the traction power hydraulic pipe.
Background technology
General high capacity waggon mainly is made up of traction headstock and superimposed trailer, and headstock is connected with superimposed trailer by connecting device and gives superimposed trailer with transmission of power.For the engineering car, generally being equipped with on superimposed trailer needs hydraulically powered mechanical device, and corresponding hydraulic power can only be provided by headstock, so is provided with hydraulic pipe between headstock and the superimposed trailer, by the hydraulic oil transmission in the hydraulic pipe.If in the vehicle ' process, hydraulic pipe is connected, hydraulic pipe can bump with car body, and at Ackermann steer angle, can produce with connecting device and stretch, bend, be easy to cause the damage of hydraulic pipe like this, so generally when vehicle ', hydraulic pipe need be disassembled, that is to say that the mechanical device of superimposed trailer can't obtain the hydraulic power of headstock and quit work in the process of moving, be difficult to satisfy the requirement of some vehicle-mounted engineering machineries.
Summary of the invention
The purpose of this utility model is to provide a kind of superimposed trailer power fluid pressure pipe draw gear, can realize that hydraulic pipe keeps connecting in the vehicle ' process, and can not cause damage to hydraulic pipe.
The utility model is to realize above-mentioned purpose like this:
Superimposed trailer power fluid pressure pipe draw gear, it is characterized in that comprising hydraulic pipe, the two ends of hydraulic pipe are connected on traction headstock and the superimposed trailer car body, and be reserved with the length of certain bending and extension, on traction headstock or superimposed trailer car body, assembly pulley is installed, this assembly pulley is located at the top of hydraulic pipe, and an end of the hoist ropes on the assembly pulley connects weight thing, other end suspension hydraulic pipe.
In addition, assembly pulley comprises two fixed pulleys, movable pulley and hoist ropes; One of them fixed pulley is installed in an end of cross bar, and another fixed pulley is installed on the top of column; The weight thing is fixed on the movable pulley, and movable pulley is installed in the column movably; Hoist ropes passes two fixed pulleys and movable pulley successively, and the one end is connected with hydraulic pipe, and the other end is fixed in the column.
The beneficial effects of the utility model are: hydraulic pipe hangs by assembly pulley and weight thing, can not produce collision with car body in normal vehicle operation; And hydraulic pipe is reserved with the length of certain bending and extension, and vehicle is in the turning process, and assembly pulley and weight thing can be made adjustment accordingly, and it is corresponding crooked or extend that hydraulic pipe is produced, and avoids damaging because of transshipping stressed causing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is running condition figure of the present utility model.
The specific embodiment
With reference to Fig. 1, superimposed trailer power fluid pressure pipe draw gear, comprise hydraulic pipe 3, the two ends of hydraulic pipe 3 are connected on traction headstock 5 and superimposed trailer 6 car bodies, and be reserved with the length of certain bending and extension, and on traction headstock 5 or superimposed trailer 6 car bodies, assembly pulley 1 being installed, this assembly pulley 1 is located at the top of hydraulic pipe 3, one end of the hoist ropes 14 on the assembly pulley 1 connects weight thing 2, other end suspension hydraulic pipe 3.For the ease of the installation of assembly pulley and the protection of draw gear; assembly pulley 1 and weight thing 2 are installed in the support 4 of being located at traction headstock or superimposed trailer car body; it comprises column 41, cross bar 42 and stud location seat 43; column 41 and cross bar 42 are hollow cylinder; column 41 rotatable being installed on the stud location seat 43; be that column 41 can reduce the stressed of hydraulic pipe with suitable the turning to of turning process of vehicle.Cross bar 42 links to each other with column 41 tops.
