Abstract
A track wheel box belongs to the technical field of construction equipment for road and bridge. The track wheel box comprises a wheel box container equipped with a wheel set on the lower part; the wheel set is connected with the motive power; a crank arm type bearing seat is equipped on the wheel; the upper end of the bearing seat is hinged with the wheel box container. Hydraulic oil lifts are hinged on the wheel boxes between every two contiguous wheels in front and back of the first wheel; hydraulic oil lift central plungers are positioned in the lower part; the lower end of the crank arm type bearing seat is hinged with the lower end of the hydraulic oil lift plunger. After the upper cavities of the wheel box hydraulic oil lifts are connected in parallel, the tail ends are connected with an accumulator; the connection tube of the upper cavity of the first hydraulic oil lift is connected with a three-position four-way valve; the lower cavities of the wheel box hydraulic oil lifts are connected with the three-position four-way valve after connecting in parallel; another end of the three-position four-way valve is connected with a hydraulic oil pump and an oil tank. The utility model is made use to convey large size prefabricated components of bridge, etc., and the equal load performance of the wheel isgood.
Description
Technical field
The utility model belongs to the road and bridge construction equipment technical field, the transportation device-Track wheel box that uses in particularly a kind of road and bridge construction.
Background technology
Roller box is a kind of transportation device commonly used in the road and bridge construction, and existing roller box set of wheels adopts concentrates whole type of drive, and whole set of wheels is used the separate unit motor-driven, and required motor power is big.If motor breaks down, just whole roller box can't use.In the roller box carrying operational process, wheel all carrying property is poor.
The utility model content
The utility model purpose is to provide all good Track wheel boxs of carrying property of a kind of wheel.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of Track wheel box, comprise that the bottom is equipped with the wheel box body of set of wheels, and set of wheels connects with power, and the bent-arm bearing seat is installed on the wheel, and the bearing seat upper end is hinged with the wheel box body; Be hinged with the hydraulic oil top on the roller box between per two adjacent wheels of first bus wheel front and back thereof, below piston is positioned in the hydraulic oil top; Bent-arm bearing seat lower end and piston lower end, hydraulic oil top are hinged.
Each wheel connects with actuating unit respectively.
End connects energy storage after the epicoele parallel connection of roller box hydraulic oil top, and first hydraulic oil top epicoele connects three-position four-way valve; Connect three-position four-way valve after the cavity of resorption parallel connection of roller box hydraulic oil top; Three-position four-way valve is termination hydraulic oil pump and fuel tank in addition.
The utility model single track four-wheel case as required is used in combination, but also double track eight roller boxs are used in combination.In being used in combination, connect by connecting distribution beam between two roller boxs, connect the distribution beam midway location and be provided with the revolution free bearing, connect distribution beam and the same prior art of revolution free bearing structure.Because wheel is hinged by bent-arm bearing seat and roller box, bearing seat lower end and piston lower end, hydraulic oil top are hinged, when pressurized inhomogeneous and make certain wheel generation upper and lower displacement, drive hydraulic oil top piston up-down, the hydraulic oil that comes out from certain hydraulic oil top enters oil circuit, and then enter in other hydraulic oil top, make other wheels that upper and lower displacement take place thereupon, thereby guarantee that all wheel pressure-bearings are even.Because wheel is hinged with the wheel box body by the bent-arm bearing seat, wheel can suitably be gone up and receive, and utilizes the utility model to cooperate with transfer cement concrete pedestal, also can realize turning to of roller box.

Fig. 2 is a double track two-wheel case back view;
Fig. 3 is a double track two-wheel case hydraulic efficiency pressure system scheme drawing.
The specific embodiment
Embodiment, a kind of double track two-wheel case, the two subordinate portions that comprise are equipped with the wheel box body 1 of set of wheels, and wheel 2 connects with reducing motor 7.Bent-arm bearing seat 3 is installed on the wheel 2, and bearing seat 3 upper ends are hinged with wheel box body 1, and 4 is hinge.Be hinged with hydraulic oil top 5 on the wheel box body between per two adjacent wheels of first bus wheel front and back thereof, below piston 6 was positioned in the hydraulic oil top 5, bent-arm bearing seat 3 lower ends and piston 6 lower ends, hydraulic oil top were hinged.The hydraulic oil of installing on two wheel box bodies 1 pushes up 5 epicoeles and takes over 15 and incorporate high pressure fuel pipe 17 back ends into and connect energy storage 8, and the first hydraulic oil of roller box one side pushes up 9 epicoeles and connects three-position four-way valve 10.The hydraulic oil of installing on two wheel box bodies 1 pushes up 5 cavity of resorptions and takes over and incorporate high pressure fuel pipe 18 back ends into and connect three-position four-way valve 10.Three-position four-way valve 10 is termination hydraulic oil pump 11 and fuel tank 12 in addition.13 is that two roller boxs connect distribution beam, and 14 for supporting the revolution pallet of weight.
Claims (3)
1, a kind of Track wheel box comprises that the bottom is equipped with the wheel box body of set of wheels, and set of wheels connects with power, it is characterized in that, the bent-arm bearing seat is installed on the wheel, and the bearing seat upper end is hinged with the wheel box body; Be hinged with the hydraulic oil top on the roller box between per two adjacent wheels of first bus wheel front and back thereof, below piston is positioned in the hydraulic oil top; Bent-arm bearing seat lower end and piston lower end, hydraulic oil top are hinged.
2, roller box as claimed in claim 1 is characterized in that, each wheel connects with actuating unit respectively.
3, roller box as claimed in claim 1 or 2 is characterized in that, end connects energy storage after the epicoele parallel connection of roller box hydraulic oil top, and first hydraulic oil top epicoele connects three-position four-way valve; Connect three-position four-way valve after the cavity of resorption parallel connection of roller box hydraulic oil top; Three-position four-way valve is termination hydraulic oil pump and fuel tank in addition.
