Description

Technical Field

[0001] The utility model belongs to the technical field of crane anti-rollover, and more specifically, particularly relates to a crane anti-rollover structure. Background Art

[0002] Crane is a kind of lifting and handling machinery widely used in ports, workshops, power plants, construction sites and other places. The name of crane is a unified title for lifting machinery. Usually, the main cranes are truck cranes, crawler cranes and tire cranes. The use of cranes is to lift equipment, rescue, hoisting, machinery and rescue.

[0003] During the operation of a crane, it is easy for the crane to roll over due to improper operation, uneven ground, external environmental factors, structural problems and other reasons, resulting in loss of life and property. In order to avoid the crane rolling over, traditional cranes will install anti-rollover legs on both sides. However, the existing anti-rollover legs are close to the crane and provide limited support force. When the crane lifts a heavy object, there is a certain risk of rollover. At the same time, the presence of anti-rollover legs will inevitably increase the width of the crane body, thereby reducing the convenience of the crane moving and parking in urban areas.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a crane anti-rollover structure is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a crane anti-rollover structure, which is achieved by the following specific technical means:

[0006] A crane anti-rollover structure comprises a vehicle body, wherein vehicle plates are installed at the middle and rear parts of the vehicle body, a crane is installed at the top of the vehicle plate near the rear part of the vehicle body, and an anti-rollover box body 1 and an anti-rollover box body 2 are fixedly installed at the top of the vehicle plate at a position located in the middle part of the vehicle body along the width direction, and the anti-rollover box body 1 and the anti-rollover box body 2 are respectively provided with slide grooves at positions close to the left and right sides of the vehicle body, and a telescopic seat is slidably connected to the inside of the slide groove, a groove is provided on one side of the telescopic seat, and a tooth plate is provided inside the groove, and a storage groove is provided at the bottom end of the telescopic seat, and a support seat is movably connected to the inside of the storage groove, and an installation groove is provided inside the support seat, and a pair of hydraulic telescopic rods are installed inside the installation groove, and the output ends of the pair of hydraulic telescopic rods extend to the bottom of the support seat and are fixedly connected to the support plate.

[0007] Furthermore, the anti-rollover box body 1 and the anti-rollover box body 2 are respectively provided with a drive box at a side position close to the slide slot opening, and a servo motor is installed on the top of the drive box. The output end of the servo motor extends to the interior of the drive box and is fixedly connected to a gear, and one side of the gear is meshed with the gear plate.

[0008] Furthermore, a rotating shaft is rotatably connected inside the storage slot at a side away from the vehicle body, and one side of the rotating shaft is fixedly connected to the support seat.

[0009] Furthermore, a limiting hole is provided on one side of the support seat and the rotating shaft, and a bayonet is connected in the limiting hole on one side of the support seat and the rotating shaft.

[0010] Furthermore, four groups of keyways are equidistantly provided on the outer side of the limiting hole, and four groups of splines are equidistantly provided on the outer side of the bayonet.

[0011] Furthermore, the latch is provided with a draw groove on one side close to the outside of the support seat.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model discloses a crane anti-rollover structure, which facilitates the movement of the telescopic seat in the slide groove through the coordinated use of a servo motor, a gear and a toothed plate, and then through the setting of a rotating shaft, the support seat can be turned downward from the storage groove and made perpendicular to the ground, and finally a pair of hydraulic telescopic rods are used to drive the support plate to contact the ground. Compared with the traditional anti-rollover legs, the anti-rollover structure greatly increases the width of the crane in contact with the ground, thereby improving the anti-rollover effect. At the same time, through the coordinated use of the storage groove, the limiting hole and the bayonet, and the engagement of the spline on the bayonet and the keyway in the limiting hole, the support seat can be recovered to the storage groove by the rotating shaft, and then by recovering the telescopic seat to the inside of the slide groove, one side of the telescopic seat is parallel to the slide groove opening, thereby avoiding the situation that the anti-rollover structure increases the width of the vehicle body and reduces the convenience of the crane in walking and parking in the urban area.

[0026] Among them, the anti-rollover box 1 2 and the anti-rollover box 2 3 are respectively provided with a driving box 8 at a side position close to the opening of the slide slot 4, and a servo motor 801 is installed on the top of the driving box 8. The output end of the servo motor 801 extends to the interior of the driving box 8 and is fixedly connected with a gear 802, and one side of the gear 802 is meshed with the tooth plate 502. Through the setting of the servo motor 801, the rotation of the gear 802 is facilitated.

[0027] Among them, a rotating shaft 601 is rotatably connected to the inside of the storage groove 6 at the side away from the vehicle body 1, and one side of the rotating shaft 601 is fixedly connected to the support seat 7. The setting of the rotating shaft 601 facilitates the flipping of the support seat 7.

[0028] A limiting hole 602 is provided on one side of the support seat 7 and the rotating shaft 601 , and a latch 604 is connected in the limiting hole 602 on one side of the support seat 7 and the rotating shaft 601 .
