Description

Technical Field

[0001] The invention relates to the technical field of caisson cross beams, in particular to a combined cross beam. Background Art

[0002] A caisson is a shaft-shaped structure, which is made by digging soil in the well and relying on its own gravity to overcome the frictional resistance of the well wall and then sinking to the designed elevation. The bottom is then sealed with concrete and the well hole is filled to make it the foundation of a bridge pier or other structure. It is generally used in the construction of foundation pits for large bridge piers, sewage pumping stations, large equipment foundations, civil air defense shelters, shield assembly wells, underground driveways and station hydraulic foundation construction enclosure devices.

[0003] The mechanically pressed caisson is different from the traditional prefabricated caisson wall, which sinks by its own weight and relies on mechanical pressure to dig the earth instead of manual excavation during excavation. The cross beam is the carrier of the excavation machinery and also the brake to achieve balance and prevent the caisson from sinking suddenly. The caisson cross beam is often made in the form of a straight beam. In a mechanically pressurized caisson, the foundation soil must be destroyed by applying load through the beam to achieve caisson. When the soil is uneven, the flat bottom of the cross beam is difficult to sink evenly, resulting in the risk of caisson imbalance. Summary of the invention

[0004] In view of the problem in the above-mentioned prior art that the blade foot suddenly sinks and affects the balance of the cross beam, the present invention is proposed.

[0005] Therefore, the technical problem to be solved by the present invention is the problem that the sudden sinking of the blade foot affects the balance of the cross beam.

[0006] To achieve the above object, the present invention provides the following technical solution: a combined cross beam, comprising:

[0007] A cross beam frame, the cross beam frame comprising a clamping sleeve, an inner connecting hole and a contact switch, the cross beam frame is provided with a clamping sleeve, an inner connecting hole is reserved in the cross beam frame, and a contact switch is provided in the inner connecting hole;

[0008] A ground-breaking blade foot, wherein a cross beam frame is arranged on the ground-breaking blade foot, a positioning boss is arranged on the ground-breaking blade foot, and the ground-breaking blade foot is connected to the cross beam frame through a mounting joint.

[0009] As a further solution of the present invention: a hydraulic joint is arranged on the clamping sleeve, and a reset seat is arranged in the inner connecting hole.

[0012] As a further solution of the present invention: a hydraulic ferrule is provided on the installation joint, and the hydraulic ferrule is connected to the hydraulic power source through a hydraulic joint.

[0013] As a further solution of the present invention: a lifting base is arranged on the earth-breaking blade foot, and a hydraulic top plate is arranged on the lifting base.

[0014] As a further solution of the present invention: the structure of the earth-breaking blade foot corresponds to the structure of the cross beam frame, and the cross beam frame is provided with at least four internal connection holes.

[0015] As a further solution of the present invention: the ground-breaking blade foot is a wedge-shaped structure, and at least a positioning boss is provided on the ground-breaking blade foot.

During construction operations, the ground-breaking work is assisted by the ground-breaking blade foot 200 arranged at the lower end. During the operation, if the blade foot brake loses control, the connection between the ground-breaking blade foot 200 and the cross beam frame 100 can be released to help maintain the balance of the cross beam frame 100.

[0033] Example 2

[0034] Combined with Figure 2 and Figure 3 and Figure 4 , it is concluded that: a hydraulic ferrule 204 is provided on the installation joint 203, the hydraulic ferrule 204 is connected to the hydraulic power source through the hydraulic joint 102, a lifting base 205 is provided on the earth-breaking blade foot 200, a hydraulic top plate 206 is provided on the lifting base 205, the structure of the earth-breaking blade foot 200 corresponds to the structure of the cross beam frame 100, and at least four internal connection holes 103 are provided on the cross beam frame 100;

[0035] Preferably, the ground-breaking blade foot 200 is a wedge-shaped structure, and at least a positioning boss 201 is provided on the ground-breaking blade foot 200.

The reset seat 105 is an annular structure, and at least six groups of contact bases 106 and connecting springs 107 corresponding to each other are provided on the reset seat 105.

[0036] In the present embodiment: by adding a connecting boss 202 to the earth-breaking blade foot 200, and by connecting the connecting boss 202 and the inner connecting hole 103 to each other, when the lower end earth-breaking blade foot 200 is offset, the hydraulic device in the jacking base 205 provided on the earth-breaking blade foot 200 can be triggered through the internal trigger structure to lift the hydraulic top plate 206, thereby helping to maintain the overall balance of the cross beam frame 100 and better maintain the balance of the cross beam.

[0041] When the earth-breaking blade 200 at the lower end is offset, the hydraulic driving device arranged inside the jacking base 205 is lifted up by the jacking base 205 arranged at the upper end of the earth-breaking blade 200 under the action of the hydraulic power source connected to the hydraulic joint 102, thereby maintaining the overall balance of the cross beam frame 100 and preventing it from being offset along with the earth-breaking blade 200.
