Problems solved by technology

[0002] When the vehicle-tyred crane is in operation, if the angle of the jib tilting backward is too large, the entire crane will tilt backward, resulting in the danger of overturning, so the general vehicle-tyred crane is equipped with an anti-tilt device. The device, generally a rigid device, achieves the anti-backward effect by the rigid collision between the jib and the anti-backward device. Although this anti-backward device can prevent back-rolling, it will cause damage to the structure of the crane and shorten the tire. The service life of the crane

Embodiment Construction

[0009] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0010] The buffer type anti-rolling device of the wheeled crane includes a mounting base 1, a ram 2, a spring 3 and a contact switch 4. The mounting base 1 is fixed on the crane and is located directly behind the jib 5 of the crane. A slot 11 is provided in the mounting seat 1, a contact switch 4 is arranged at the center of the bottom of the slot 11, the spring 3 is set on the outside of the contact switch 4, one end of the spring 3 is fixed on the bottom of the slot 11, and the other end is Fixed on the contact contact platform 21 provided at one end of the lance 2, the contact contact platform 21 is arranged in the slot 11, the other end of the lance 2 extends to the outside of the slot 11, and an impact platform 22 is provided, And the outer side of the impact platform 22 is pasted with a buffer rubber layer 23 , and the contact switch...

Abstract

The invention relates to a wheel type crane buffer type anti-back-tipping device which comprises a mounting seat, an impacting bar, a spring and a contact switch; the mounting seat is fixed on a crane and just behind a crane arm stand; a groove hole is formed in the mounting seat; the contact switch is arranged in the center of the bottom of the groove hole; the spring sleeves the outer side of the contact switch; one end of the spring is fixed at the bottom of the groove hole; the other end of the spring is fixed on the impacting bar; the other end of the impacting bar extends outside the groove hole; a buffer rubber layer is adhered to the end part, at one end of the outer side of the groove hole, of the impacting bar; and the contact switch is electrically connected with a drive motor of the arm stand. According to the wheel type crane buffer type anti-back-tipping device, with matching of the contact switch and the spring, overranging back tipping of the arm stand is prevented, and the safety of the crane is guaranteed; and meanwhile, non rigid collision due to back tipping prevention exists, damage on the crane is reduced, and the service life of the crane is prolonged.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a buffer type anti-dipping device for a wheeled crane. Background technique [0002] When the vehicle-tyred crane is in operation, if the angle of the jib tilting backward is too large, the entire crane will tilt backward, resulting in the danger of overturning, so the general vehicle-tyred crane is equipped with an anti-tilt device. The device, generally a rigid device, achieves the anti-backward effect by the rigid collision between the jib and the anti-backward device. Although this anti-backward device can prevent back-rolling, it will cause damage to the structure of the crane and shorten the tire. service life of the crane. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has conducted research and improvement, and provides a buffer type anti-tilt device for a wheeled crane that is in buffer contact with the jib. [0004] The technic...
