Abstract
The utility model discloses a cart of a tire planking crane. The cart comprises two supporting legs, a wheel frame and a ground transverse beam; the wheel frame is installed below the two supporting legs; the ground transverse beam is used for connecting the two supporting legs; a dovetail groove adjusting mechanism installed between each supporting leg and the wheel frame is used for adjusting span between the two supporting legs; and a supporting oil cylinder installed on the ground transverse beam is used for changing the span between the supporting legs after jacking the planking crane. The dovetail groove adjusting mechanisms adopted by the cart are closed guide rails with less mutual contact; an inlaid strip can be used for adjusting a gap between an upper dovetail and a lower dovetail; and the dovetail groove adjusting mechanisms are compact in size and convenient in adjustment. Simultaneously, a dovetail boss matches with an adjusting screw rod; the running distance of the dovetail boss can be precisely adjusted by rotating the screw rod through a hand wheel; and the span between the two supporting legs is enabled to accurately reach the position needed by users. The cart also uses a steering mechanism formed by a steering cylinder and the wheel frame to control rotation angles of wheels and enable the wheels to be adaptable to deviation adjustment and curve segment work when running on different road beds.
Description
Technical field
The utility model relates to a kind of non-slag rail construction equipment that is used for the high speed railway railway line for passenger traffic, relates generally to a kind of cart of rubber-tyred bed board hoisting crane.
Background technology
Rubber-tyred bed board hoisting crane is a kind of non-slag rail construction equipment of high speed railway railway line for passenger traffic.Present wheel-track type gantry crane and rubber tired crane, all the rectangular guideway structure that adopts between its supporting leg and the wheel, contact surface is more between the guide rail of this structure, force of sliding friction is bigger between the guide rail, cause becoming and stride inconvenience, cause supporting leg to become striding precision low, under the tunnel of different spaces size, roadbed, the bridge floor operating mode, need the bed board machine of different spans size, wasted resource widely; And the thrust baring of existing wheel can only bear pressure, and complex structure, and fabrication and installation, maintenance are inconvenient, and under curved surface or some irregular operating modes, sideslip easily can not promptly and accurately be adjusted the correct direction of traveling wheels.
The utility model content
The purpose of this utility model is to provide a kind of both can regulate the supporting leg span, can regulate the cart of rubber-tyred bed board hoisting crane of the steering angle of wheel again.
The cart of this rubber-tyred bed board hoisting crane that the utility model provides, comprise two supporting legs, be installed in vehicle wheel frame and the ground crossbeam that is used to be connected two supporting legs below two supporting legs, the dovetail furrow regulating mechanism has been installed between described supporting leg and the vehicle wheel frame, be used to regulate the span between described two supporting legs, be equipped with on the described ground crossbeam and be used for carrying out behind the jack-up bed board hoisting crane supporting leg and become the support cylinder of striding.
An oil cylinder that turns to that is used to make wheel steering is housed on the described vehicle wheel frame, the revolution support that is used to make wheel steering is housed between described dovetail furrow regulating mechanism and the vehicle wheel frame.
Precision when turning to is equipped with angular transducer on the described vehicle wheel frame.
This dovetail furrow regulating mechanism that the utility model adopts is a kind of closed guideway, contact less each other, an available panel adjustment is the gap between the dovetail up and down, compact dimensions, easy to adjust, the dovetail boss cooperates with the adjusting screw mandrel simultaneously, but by handwheel turn screw mandrel precise adjustment dovetail boss range ability, makes the span between two supporting legs accurately reach user's desired location.The utility model also utilizes the steering hardware that turns to oil cylinder and vehicle wheel frame to form to control the anglec of rotation of wheel, makes it can be applicable to the adjustment of different roadbed face traveling sideslip, segment of curve operation.

The specific embodiment
From Fig. 1 and Fig. 5 as can be seen, the cart of this rubber-tyred bed board of the utility model hoisting crane, comprise two supporting legs 1, be installed in the vehicle wheel frame 2 below two supporting legs and be connected ground crossbeam 3 between two supporting legs, a dovetail furrow 41 is arranged in the bottom of supporting leg 1, the dovetail boss 42 that matches with dovetail furrow 41 is at the top that is fixed on vehicle wheel frame 2 by the single-revolution support and connection, one adjusting screw mandrel 43 passes dovetail boss 42 and connects by screw pair, the one end links to each other with a wheel disc 44, dovetail furrow 41, dovetail boss 42, regulate screw mandrel 43 and wheel disc 44 and formed dovetail furrow regulating mechanism 4 jointly, one external part 21 should be arranged in the side of vehicle wheel frame 2, this external part 21 turns to oil cylinder 5 to be connected with one, the angular transducer in addition that links to each other with vehicle wheel frame 2.A support cylinder 31 is housed on ground crossbeam 3.
When the need change is striden, with support cylinder 31 jack-up bed board hoisting cranes, rotate and regulate screw mandrel 43, dovetail boss 42 is slided in dovetail furrow 41, thereby moving to reach to become, drive vehicle wheel frame 2 strides purpose, the vertical span of this mechanism's adjustable legs (8.65-9.45m) is applicable to the operation under the tunnel, roadbed, bridge floor operating mode of different spaces size.
When need turn to, regulate the rotation of vehicle wheel frame 2 by turning to stretching of oil cylinder 5, the angle that turns to by the angular transducer accuracy control simultaneously, thus realize the needs to different roadbed face, segment of curve operation of the present utility model.
