Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a steel bar shearing machine for building construction. Background Technology
[0002] Steel bars are used in building construction to reinforce and strengthen concrete structures. They also improve the earthquake resistance of buildings, facilitate construction, and act as lightning conductors. However, after the building is completed, some of the steel bars are often exposed. To prevent workers from being injured by the exposed steel bars, a special shearing machine is usually used to cut them off.
[0003] Existing steel bar shearing machines for building construction mostly require manual operation by workers to move the shearing machine along the steel bar. Because these machines rely on gravity, they are time-consuming and labor-intensive to use, and can only shear one steel bar at a time, resulting in low shearing efficiency. Therefore, those skilled in the art have provided a steel bar shearing machine for building construction to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing steel bar shearing machines for building construction, which require manual support from workers to move the shearing machine onto the steel bar. These machines are also time-consuming and labor-intensive due to their gravity-based operation, and can only shear one steel bar at a time, resulting in low shearing efficiency. Therefore, this invention proposes a steel bar shearing machine for building construction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel bar shearing machine for building construction, comprising a base, two sets of electrically telescopic support legs symmetrically distributed on the top of the base, two sets of universal wheels symmetrically distributed on the bottom of the base, a push handle fixed to the middle of one end of the top of the base, a mounting box fixed to the top of the electrically telescopic support legs, a push-adjustment slide plate slidably connected to the upper inner side of the mounting box, a set of electrically telescopic push rods slidably connected to the lower part of the push-adjustment slide plate, and a cutting disc provided on one side of the electrically telescopic push rods;
[0006] With the above technical solution, during use, the device is pushed by a pusher, and then the universal wheels move the device towards the position of the rebar to be cut via the base fixed at the top. When the device moves to the position of the rebar to be cut, the electric telescopic support legs drive the mounting box fixed at the top to move upward, thereby driving the cutting disc on the front side of the mounting box to move upward. When the cutting disc moves to the beginning of the protruding rebar, it slides and pushes the sliding plate towards the front of the mounting box, causing a set of electric telescopic push rods to slide towards the left and right ends of the mounting box. This causes the cutting discs on the front side of the electric telescopic push rods to slide and pull apart to a certain distance, so that the distance between the cutting discs matches the distance between a set of rebars. Then, the electric telescopic push rods push the cutting discs on the front side to slide towards the protruding beginning of the rebar, cutting the protruding rebar. This facilitates quick cutting of protruding rebars, allows for cutting multiple rebars at once, and makes rebar cutting more convenient, time-saving, and labor-saving.
[0007] Furthermore, a push-adjustment groove is provided at both the left and right ends of the upper surface of the push-adjustment slide plate. A column block is slidably connected to the inner side of the push-adjustment groove. A hanging plate is fixed at the bottom end of the column block. A first limiting plate is fixed at the front side of the bottom end of the hanging plate. A second limiting plate is fixed at the rear side of the bottom end of the hanging plate. The front and rear sides of the electric telescopic push rod are respectively connected to the middle of the first limiting plate and the second limiting plate. A first guide groove is provided at the bottom of the front surface of the mounting box.
[0008] With the above technical solution, when the sliding plate slides towards the front of the mounting box, the sliding groove on the upper surface of the sliding plate moves forward under the action of the sliding plate. The inclined surface of the sliding groove will push the hanging plate fixed at the bottom of the column block through the inner sliding connection of the column block. Under the restriction of the first limiting plate and the second limiting plate fixed on the lower surface of the hanging plate, the hanging plate slides steadily towards the left and right ends of the mounting box along the restriction of the first guide groove. This will drive the electric telescopic push rods installed on a set of hanging plates to slide slowly towards the left and right ends of the mounting box, thereby improving the stability of the left and right sliding of the electric telescopic push rods.
[0009] Furthermore, a cutting blade mounting plate is fixed to the front side of the electric telescopic push rod, the cutting blade disc is located below the front side of the cutting blade mounting plate and is rotatably connected to the cutting blade mounting plate, a second gear is fixed to the middle of the top of the cutting blade disc, a first gear is meshed with the middle of the rear side of the second gear, a motor is fixed to the top of the first gear, and the rear side of the motor is fixedly connected to the cutting blade mounting plate.
[0010] With the above technical solution, during cutting, the electric telescopic push rod drives the cutting blade mounting plate fixedly connected to the front to move towards the reinforcing bar. As the cutting blade mounting plate moves towards the reinforcing bar, it drives the cutting blade disc located below the front of the cutting blade mounting plate to move towards the reinforcing bar. At the same time, the motor drives the first gear fixedly connected to the output end to rotate. The rotating first gear drives the second gear meshed with the front to rotate. The rotating second gear drives the cutting blade disc fixedly connected to the bottom to rotate. The rotating cutting blade disc cuts the reinforcing bar in contact, making it easy to quickly cut the reinforcing bar apart.
[0011] Furthermore, the first limiting plate is slidably connected to the mounting box via the first guide groove, and a third guide groove is provided in the middle of the lower inner surface of the mounting box. The bottom of the second limiting plate passes through the third guide groove and is slidably connected to the third guide groove.
[0012] With the above technical solution, when the hanging plate slides into one end of the mounting box, the first limiting plate fixed on the front side of the bottom of the hanging plate will slide along the first guide groove to one end, and the second limiting plate fixed on the rear side of the bottom of the hanging plate will slide along the third guide groove opened in the middle of the bottom of the mounting box to one end, which helps to improve the stability of the hanging plate sliding left and right.
[0013] Furthermore, a positioning block is fixed on the upper part of the inner wall at both the left and right ends of the mounting box, and a second guide groove is opened in the middle of both the left and right ends of the push-adjustment slide plate. The second guide groove is slidably connected to the positioning block in the front and back. The push-adjustment slide plate is slidably connected to the mounting box through the second guide groove and the positioning block.
[0014] With the above technical solution, when the sliding plate slides to the front of the mounting box, the second guide groove opened in the middle of its left and right ends will move forward along the positioning block fixed on the upper part of the inner wall of the mounting box, which helps to prevent the position of the sliding plate from shifting during the forward and backward sliding process.
[0015] Furthermore, a screw cavity is provided in the middle of the inner side of the sliding plate, and an adjusting screw rod passes through the inside of the screw cavity. The rear side of the adjusting screw rod is connected through to the upper part of the rear side of the mounting box, and the adjusting screw rod is rotatably connected to the mounting box.
[0016] By rotating the adjusting screw to one end, the adjusting screw will push the sliding plate towards the front of the mounting box through the screw cavity, which facilitates the provision of thrust to the sliding plate.
[0017] This utility model has the following beneficial effects:
[0018] 1. In this utility model, during use, the device is pushed by a pusher, and then the universal wheels drive the device to the position of the rebar to be cut via the base fixedly connected to the top. When the device moves to the position of the rebar to be cut, the electric telescopic support legs drive the mounting box fixedly connected to the top to move upward, thereby driving the cutting disc provided on the front side of the mounting box to move upward. When the cutting disc moves to the beginning of the protruding rebar, it slides and pushes the sliding plate to the front side of the mounting box, driving a set of electric telescopic push rods to slide relative to the left and right ends inside the mounting box. This causes the cutting discs provided on the front side of the electric telescopic push rods to slide and pull apart to a certain distance, so that the distance between the cutting discs matches the distance between a set of rebars. Then, the electric telescopic push rods push the cutting discs provided on the front side to slide towards the protruding beginning of the rebar, cutting the protruding rebar. This facilitates quick cutting of protruding rebars, allows for cutting multiple rebars at once, and makes rebar cutting more convenient, time-saving, and labor-saving. Attached Figure Description
