Description

Technical Field

[0001] The utility model relates to the technical field of construction waste crushing, in particular to a torsion crushing device for discarded concrete support beams. Background Art

[0002] Waste concrete support beams are waste generated during construction. They are usually located above the foundation or between abutments to prevent the thrust of fill from causing the abutment to move. Processing these waste support beams can not only reduce environmental pollution, but also save resources and reduce production costs. Waste concrete support beam torsion crushing equipment is a mechanical equipment specially designed for crushing support beams in concrete structures.

[0003] Chinese patent announcement number CN220861554U discloses a torsion crushing device for abandoned concrete support beams, including a device base, a sleeve, a connecting ring, a torsion cylinder and a gear ring, a torsion motor is fixedly connected to the inner side wall of the sleeve near the gear ring, a gear meshing with the gear ring is fixedly connected to the output end of the torsion motor, an electro-hydraulic push rod is fixedly connected to the inner side wall of the torsion cylinder, an extrusion plate is fixedly connected to the output end of the electro-hydraulic push rod, and a crushing tooth is fixedly connected to the side of the extrusion plate away from the electro-hydraulic push rod. The torsion crushing device effectively improves the crushing efficiency of the device through the coordination of the device base, sleeve, connecting ring, torsion cylinder, gear ring, torsion motor, gear, electro-hydraulic push rod, extrusion plate and crushing teeth, and tries to avoid the large noise caused by crushing with a pick head machine.

[0004] However, the above technical solution has the following shortcomings: when the device clamps the support beam, the electro-hydraulic push rod pushes the extrusion plate and the crushing teeth to move to the side away from the torsion cylinder until they abut the support beam. The structure only clamps the support beam by lateral clamping force, and the clamping effect on the support beam is poor. As a result, when the crushing teeth rotate, the crushing teeth and the support beam are prone to relative sliding, and the axial torque of the connecting ring is large, affecting the stability of the structural connection.

[0025] The engaging assembly is provided with a control structure for adjusting the clamping force, and the control structure comprises a first motor 3 provided on the rotating drum 2, and the first motor 3 is drivingly connected to the rotating rod 4.

[0026] When the cut support beam needs to be twisted and crushed, the support beam is first placed in the crushing box 1, and the first motor 3 is started to drive the rotating rod 4 to rotate so that the external thread 5 is screwed with the movable plate 9. The movable plate 9 drives the connecting rod 10 to move along the axial direction of the rotating rod 4 and close to the fixed frame 6. At the same time, the connecting rod 10 drives the rotating frame 8 to rotate. The rotating frame 8 rotates with the end close to the fixed block 7 as the rotation center, and then the rotating frame 8 drives the two clamps 11 to approach each other until the clamps 11 clamp the support beam with a large clamping force, and the structure is stable during crushing.
