Description

Technical Field

[0001] The utility model relates to the field of the hanging and connecting structure of a bridge erecting machine, in particular to a walking type adaptive sling for installing a steel main beam of a bridge erecting machine. Background Technique

[0002] During the existing bridge construction process, a bridge erecting machine is usually used to build a bridge. The bridge erecting machine has a simple structure and is convenient to use. It usually consists of a main truss, a front outrigger, a middle outrigger, a rear outrigger and a hoisting mechanism. The front outrigger, the middle outrigger and the rear outrigger are respectively arranged at the front, middle and rear parts of the bottom surface of the main truss. The hoisting mechanism includes a trolley and a sling. The trolley is arranged on the top of the main truss. A hoisting device is arranged on the trolley. The hoisting device is connected with the sling. The sling is used for hoisting relevant components for beam lifting operation and beam lowering operation.

[0003] The sling in the prior art has a simple structure and is fixedly connected with the winch. Therefore, during the hoisting process, the component can only be in a horizontal state, and the hoisting direction and hoisting angle of the framework cannot be adjusted. In this way, during the hoisting process, due to the setting of some construction auxiliary facilities, the component may be blocked, which will slow down the construction progress. Moreover, after the component is hoisted to the designated position, it will shake, and the fixed sling cannot affect and adjust the shake in time. Therefore, not only the stability during the hoisting process is poor, but also the shake cannot be adjusted and stopped in time after the component is hoisted to the designated position, which affects the construction efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a walking type adaptive sling for installing a steel main beam of a bridge erecting machine, and solve the problem that the existing slings are generally fixed slings and cannot adjust the hoisting direction and hoisting angle of the hoisted component.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A walking type adaptive sling for installing a steel main beam of a bridge erecting machine includes a horizontal rotation connection mechanism, a vertical longitudinal axis rotation connection seat, a longitudinal beam, a vertical transverse axis rotation connection seat and a cross beam. The horizontal rotation mechanism includes a steel cable connection part and a rotation socket part which are arranged from top to bottom in sequence. The steel cable connection part is connected with the steel cable of the hoisting mechanism.

The vertical longitudinal axis rotation connection seat is arranged on the lower part of the rotation socket part. The bottom of the vertical longitudinal axis rotation connection seat is rotatably connected with the middle part of the longitudinal beam. Longitudinal beam angle adjustment hydraulic adjustment mechanisms are arranged on both sides of the vertical longitudinal axis rotation connection seat. The vertical transverse axis rotation connection seat is arranged at the bottom of the longitudinal beam. The bottom of the vertical transverse axis rotation connection seat is rotatably connected with the middle part of the cross beam. Cross beam angle hydraulic adjustment mechanisms are arranged on both sides of the longitudinal beam.

[0007] First, the horizontal orientation of the component can be adjusted through the horizontal rotation mechanism, and it can rotate 90 degrees in the horizontal direction. This can achieve the lateral transportation of the main girder segment of the steel truss beam and then rotate it to the longitudinal installation. Such hoisting can avoid some construction auxiliary facilities and is more efficient. Then, the longitudinal angle of the hoisted component can be adjusted through the longitudinal beam angle adjustment hydraulic adjustment mechanism, and the lateral angle of the hoisted component can be adjusted through the cross beam angle adjustment hydraulic adjustment mechanism. This can achieve the adjustment of the attitude of the main girder segment during the hoisting process, and the positioning, position adjustment, and adjustment are convenient, the hoisting process is more stable, and the component can be quickly stabilized after hoisting, with higher efficiency.

[0008] As a further preference of the present utility model, a rotating motor is provided at the bottom of the steel cable connection part. The output shaft of the rotating motor is arranged downward, a driving gear is provided in the middle of the output shaft of the rotating motor, and a ring gear row is provided at the position on the upper part of the inner wall of the rotating socket part opposite to the driving gear, and the driving gear meshes with the ring gear row.

[0009] By rotating the rotating motor, the rotating socket part can be quickly rotated, thereby guiding the cross beam and longitudinal beam of the spreader to rotate in the horizontal direction.

[0010] As a further preference of the present utility model, the longitudinal beam angle adjustment hydraulic adjustment mechanism includes a longitudinal beam adjustment hydraulic cylinder. The top of the longitudinal beam adjustment hydraulic cylinder is rotatably connected to the side wall of the longitudinal rotating seat, and the output shaft of the longitudinal beam hydraulic cylinder is obliquely downward and rotatably connected to the top surface of the longitudinal beam.

[0011] Through the two longitudinal beam adjustment hydraulic cylinders on both sides of the longitudinal rotating seat, the angle of the longitudinal beam can be conveniently and quickly adjusted, thereby adjusting the longitudinal angle of the hoisted component, and the maximum adjustment amplitude is 5%.

[0012] As a further preference of the present utility model, the cross beam angle adjustment hydraulic adjustment mechanism includes a cross beam adjustment hydraulic cylinder. The top of the cross beam adjustment hydraulic cylinder is rotatably connected to the side wall of the longitudinal beam, and the output shaft of the cross beam hydraulic cylinder is obliquely downward and rotatably connected to the top surface of the cross beam.

[0013] Through the two cross beam adjustment hydraulic cylinders on both sides of the longitudinal beam, the angle of the cross beam can be conveniently and quickly adjusted, thereby adjusting the lateral angle of the hoisted component, and the maximum adjustment amplitude is 5%.

[0014] As a further preference of the present utility model, lifting lugs are provided on both sides of the bottom of the cross beam.
