Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a cutting device for grooving in building construction. Background Technology

[0002] Grooving plays a crucial role in building construction. Proper grooving ensures the depth and stability of the foundation, enabling the building to better support the weight of the superstructure and resist various geological conditions and external forces. Grooving is also a preliminary step for laying pipes and cables, providing suitable space for them, ensuring smooth installation paths that meet safety and functional requirements, and facilitating later maintenance and repair.

[0003] The main method for grooving and cutting joints in building construction is mechanical cutting, which uses cutting equipment with diamond saw blades. The cutting force is generated by the high-speed rotation of the saw blades. A small part is also done manually, which involves manually chiseling with a chisel and hammer, or using an impact drill to drill holes and then connect them to form a joint. However, the manual chiseling method is relatively inefficient and it is difficult to guarantee the accuracy.

[0004] Nowadays, manual slit cutting tools are gradually being replaced by electric slit cutting machines. Electric slit cutting machines have made significant progress in improving cutting speed and reducing manual labor intensity. However, current slit cutting devices still cannot control the depth of the cut well when faced with grooving requirements of different depths, and all workers have to bend over, which is a great burden on them. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cutting device for grooving in building construction, which aims to improve the existing technology, which still cannot control the cutting depth well when facing grooving requirements of different depths, and all work requires bending over, which is a great burden on workers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grooving cutting device for building construction, comprising a support frame, a fixed column fixedly connected between two adjacent supports, a plurality of bearing beams fixedly connected to the middle of the fixed column, a motor fixedly connected to the outer wall of the bearing beam via a fixed ring, a blade fixedly connected to the output end of the motor, a connecting block fixedly connected between two adjacent bearing beams, a sliding column slidably connected to the middle of the connecting block, a rack fixedly connected to the inner wall of the sliding column, a gear meshing with the outer wall of the rack, a crank fixedly connected to the middle of the gear, the outer wall of the crank rotatably connected to the outer wall of the bearing beam, and an angle adjustment structure provided above the bearing beam, the angle adjustment structure being used for a pushing device.

[0007] As a further description of the above technical solution:

[0008] The angle adjustment structure includes a structural column, which is fixedly connected between two adjacent load-bearing beams. A push rod is rotatably connected to the outer wall of the load-bearing beam. A groove is opened on the outer wall of the push rod. A U-shaped block is slidably connected to the inner wall of the groove. A support rod is rotatably connected to the inner wall of the U-shaped block. A rotating ring is fixedly connected to the other end of the support rod. The inner wall of the rotating ring is rotatably connected to the outer wall of the fixed column.

[0009] As a further description of the above technical solution:

[0010] The two adjacent supports are rotatably connected by an axle, and the two ends of the axle are rotatably connected to a rear wheel.

[0011] As a further description of the above technical solution:

[0012] A push handle is fixedly connected to the top of the push rod, and a rubber sleeve is fixedly connected to the outer wall of the push handle.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the connecting block is threaded with a locking screw, and the outer wall of the crank handle is rotatably connected with a sleeve.

[0015] As a further description of the above technical solution:

[0016] A fixing block is fixedly connected to the outer wall of the U-shaped block, and a locking screw is fixedly connected to the outer wall of the fixing block.

[0017] As a further description of the above technical solution:

[0018] A flat fork is fixedly connected to the bottom surface of the sliding column, and a front wheel is rotatably connected to the middle of the flat fork.

[0019] As a further description of the above technical solution:

[0020] A reinforcing column is fixedly connected to the outer wall of the bracket, and the other end of the reinforcing column is fixedly connected to the outer wall of the load-bearing beam.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when it is necessary to adjust the cutting depth, the crank handle is turned, the gear rotates, the gear position is fixed, and the inner wall of the sliding column is provided with a rack that meshes with the gear. The rotation of the gear causes the sliding column to rise or fall as a whole, and the motor fixed on the bearing beam also rises or falls. Tightening the locking screw locks the position of the sliding column, thereby realizing the adjustment of the cutting depth, which can improve the construction quality and ensure the effect of subsequent processes.

[0023] 2. In this utility model, the rotating ring drives the support rod to rotate, and the slider at the other end of the support rod slides inside the U-shaped block. The angle of the push rod can be adjusted by changing the angle between the support rod and the push rod, which can accommodate construction workers of different heights and operating habits, making the application of force more comfortable and convenient, reducing labor intensity. In narrow construction spaces, the angle can be flexibly adjusted, which is convenient for moving and positioning the equipment, improving construction efficiency and accuracy.

The load-bearing beam 4 is used to distribute the load and enhance the overall stability of the equipment.

[0040] Working principle: When the cutting depth needs to be adjusted, crank the handle 11, the gear 10 rotates, the position of the gear 10 is fixed, and the inner wall of the sliding column 8 is provided with a rack 9 that meshes with the gear 10. The rotation of the gear 10 causes the sliding column 8 to rise or fall as a whole, and the motor 5 fixed on the bearing beam 4 also rises or falls. Tighten the locking screw 22 to lock the position of the sliding column 8, thereby realizing the adjustment of the cutting depth, which can improve the construction quality and ensure the effect of subsequent processes.

[0041] Rotating the rotating ring 205 drives the support rod 204 to rotate, and the slider at the other end of the support rod 204 slides inside the U-shaped block 203. By changing the angle between the support rod 204 and the push rod 201, the angle of the push rod 201 can be adjusted, which can accommodate construction workers of different heights and operating habits, making the application of force more comfortable and convenient, reducing labor intensity. In narrow construction spaces, the angle can be flexibly adjusted, facilitating the movement and positioning of operating equipment, and improving construction efficiency and accuracy.
