Abstract
The utility model discloses a support leg for operation of a bridge inspection vehicle. The support leg comprises a support and rollers, wherein the rollers are movably connected to the support and movably connected with the support through slewing bearings, and a central position of each slewing bearing is deviated from a center line of the corresponding roller. The support leg is automatically steerable along with the vehicle, so that wear of the rollers is reduced greatly and the service life of the support leg is prolonged. Adaptability of the bridge inspection vehicle is improved by the aid of automatic steering function of the support leg, and convenience is brought to inspection.
Description
Technical field
The utility model relates to a kind of parts of bridge inspection vehicle, relates in particular to bridge inspection vehicle operation supporting leg.
Background technology
Bridge inspection vehicle is a kind of special vehicle that is specifically designed to bridge detection, maintenance construction operation.Bridge inspection vehicle can be propped in the vehicle body both sides in operation process and play the supporting leg that increases supporting power, firm vehicle body effect.For example on November 22nd, 2006 disclosed Chinese patent, publication number is CN2839050Y, patent name is that bridge detects Operation Van's supporting leg.This bridge detects Operation Van's supporting leg and is provided with a support, and an end of support connects to ground, and the other end is connected with the supporting leg wheel, connects to ground by support oil cylinder in the middle part of support.This supporting leg is not owing to there is steering hardware, so supporting leg can only be kept straight in the car operational process.Like this, can produce violent friction with the road surface at the Ackermann steer angle supporting leg, it is very difficult to make supporting leg turn.Violent friction causes the supporting leg wheel to be subjected to severe wear, has shortened the service life of supporting leg.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of bridge inspection vehicle operation supporting leg that can turn with vehicle body.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this bridge inspection vehicle operation comprises support, roller with supporting leg, described roller is movably connected on the support, described roller flexibly connects by pivoting support and support, and the line of centers position of roller is departed from the center of described pivoting support.Automatic steering and find balance position after this structure can make roller be subjected to ground-surface friction force when vehicle body is turned, and then reach the purpose of supporting leg with the car automatic steering.
As of the present utility model preferred, be provided with two rollers on the described support at least, each roller all flexibly connects by pivoting support and support, and the line of centers position of roller is departed from the center of described pivoting support.A plurality of rollers can better support vehicle body, make vehicle body more stable when operation.
As of the present utility model preferred, the in line row of the Roller pen on the described support.Can improve the crossing ability of roller when curved excessively like this.
The utility model adopts technique scheme: the bridge inspection vehicle operation can be with the car automatic steering with supporting leg, thereby has significantly reduced the wearing and tearing of roller, prolongs the service life of supporting leg.The auto-steering function of supporting leg has promoted the comformability of whole bridge inspection vehicle, also provides convenient for testing process simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done further and to be specified.
Fig. 1 is the front view of a kind of bridge inspection vehicle operation of the utility model with supporting leg;
Fig. 2 is the right elevation of Fig. 1.
The specific embodiment
As described in Figure 1, the bridge inspection vehicle operation comprises support 1, roller 2 with supporting leg.Support 1 is the T shape of handstand, and top is used for and body contact; The bottom is used to connect roller 2.This bridge inspection vehicle operation is provided with 2, two rollers 2 of two rollers with supporting leg and is evenly distributed on support 1 bottom, and each roller 2 all passes through pivoting support 5 and flexibly connects with support 1.As shown in Figure 2, roller 2 is equipped with rotating shaft 4 at position of center line, and roller 2 is connected on the pivoting support 5 by connecting panel 3 in rotating shaft 4 both sides.In the horizontal direction, the center of pivoting support 5 deviates from the line of centers position of roller 2; And two roller 2 front and back are arranged straight.
When Vehicular turn travelled, what roller 2 was subjected to changed from ground-surface friction force direction, and roller 2 this moment direction to turn inside diameter under the effect of pivoting support 5 is rotated.Roller 2 resets when Vehicular turn travels end back continuation straight-line travelling.Like this, by pivoting support 5, and the design of the off-centre between pivoting support 5 and the roller 2 makes supporting leg have the function of automatic steering when travelling with car.
