Description

Technical Field

[0001] This utility model relates to the field of steel bar cutting technology, specifically a steel bar cutting mechanism for pile foundations. Background Technology

[0002] As a type of deep foundation, pile foundation connects the tops of multiple piles into a whole through a pile cap, which together bears dynamic and static loads. In pile foundation construction technology, steel piles need to be driven in first. After the pile foundation and the pile body are connected, concrete can be poured to make the entire pile foundation form a solid integral structure. During the construction process, it is often necessary to cut the steel bars on the pile foundation to meet construction requirements. The steel bar cutting mechanism for pile foundation is a special equipment for cutting steel bars in pile foundation construction. It can quickly and efficiently cut the steel bars on the pile foundation through mechanical cutting.

[0003] According to Chinese Utility Model Publication No. CN220259421U, a cutting device for the head of rebar in pile foundations is disclosed. 1. This utility model, by setting a moving mechanism, starts a first motor, which drives a first threaded rod to rotate. The first threaded rod drives a rotating wheel to rotate, and the rotating wheel drives a driven wheel to rotate via a belt. The driven wheel drives a second threaded rod to rotate, and the first and second threaded rods drive a slider to move. The slider's movement drives a moving platform to move, and the moving platform drives the cutting blade to move, thereby adjusting the cutting length of the rebar head; 2. This utility model, by setting a clamping mechanism, starts a second motor, which drives a gear to rotate. The gear drives a first toothed plate and a second toothed plate to move, and the first and second toothed plates respectively drive two moving plates to move. The moving plates drive a clamping frame to move, thereby fixing and clamping the rebar head.

[0004] However, there are some problems to consider when implementing the above technical solutions: First, the device only clamps the bottom of the rebar, which causes the unfixed rebar head to be thrown off by the force at an instant, causing injury to the operator. Also, the cutting speed using a saw is slow. Second, after positioning, the device can only operate on a single rebar. A pile foundation has multiple rebars, which requires repeated positioning, making the work cumbersome and inefficient. Utility Model Content

[0013] Preferably, the top of the hydraulic shear is provided with a clamping plate, the clamping plate being positioned corresponding to the hydraulic shear, and the clamping plate being made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model uses a clamping plate to hold the steel bar to be cut from above, preventing the steel bar head from being thrown off by the force during cutting and causing injury to the operator. It also uses a hydraulic shear to cut the steel bar.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 An embodiment of this utility model provides a steel bar cutting mechanism for pile foundations, including a base 1 and an adjusting cutting mechanism 3. A lifting ring 2 is provided on the top of the base 1, and the adjusting cutting mechanism 3 is provided on the outside of the lifting ring 2. A first threaded rod 301 is provided on the outside of the lifting ring 2, and a movable ball 302 is provided below the first threaded rod 301.

[0028] Specifically, the bottom of the movable ball 302 is movably connected to a support leg 303. The support leg 303 forms a movable structure with the base 1 through the first threaded rod 301 and the movable ball 302. A crank 304 is provided at the top of the first threaded rod 301. Rotating the crank 304 causes the first threaded rod 301 to move within the base 1, adjusting the height and balance of the base 1. The movable ball 302 allows the angle of the support leg 303 to change within a certain range, making the support more stable when used in the foundation pit.

[0029] Specifically, a measuring seat 305 is provided on the front of the base 1, a measuring ruler 306 is provided inside the measuring seat 305, and a level 307 is provided on the top of the measuring seat 305. The level 307 can determine whether the cutting mechanism is horizontal and ensure that the elevation of the rebar head is consistent after cutting.

[0030] Specifically, a support 308 is provided on the front of the lifting ring 2, and a motor 309 is provided on the left side of the support 308. The motor 309 is connected to one end of the second threaded rod 310. A limit rod 311 is provided on the front of the second threaded rod 310. A slide block 312 is slidably connected to the outside of the limit rod 311. The slide block 312 forms a movable structure with the base 1 through the second threaded rod 310 and the motor 309. When the motor 309 works, it drives the second threaded rod 310 to rotate, so that the slide block 312 moves left and right to adjust its position relative to the position of the steel bar, which is convenient for cutting.

[0031] Specifically, a protective sleeve 313 is provided on the outer side of the second threaded rod 310. The protective sleeve 313 is matched with the size of the second threaded rod 310. Two sets of protective sleeves 313 are provided to prevent dust from the construction site from adhering to the threads of the second threaded rod 310, which would cause friction between the slide block 312 and the second threaded rod 310 when the slide block 312 moves, resulting in thread damage and affecting service life.

[0032] Specifically, a telescopic rod 314 is provided on the top of the slide block 312. The telescopic rod 314 is fixedly connected to the slide block 312. The telescopic rod 314 is arranged parallel to the base 1. The telescopic rod 314 causes the hydraulic shear 315 to move towards the reinforcing bar.

[0033] Specifically, a hydraulic shear 315 is provided at one end of the telescopic rod 314. The hydraulic shear 315 is fixedly connected to the telescopic rod 314. The hydraulic shear 315 forms a movable structure with the slide block 312 through the telescopic rod 314. When the hydraulic shear 315 works, it cuts the steel bar. The hydraulic shear 315 can quickly complete the cutting of the steel bar in a short time, and the cutting force is uniform, which can ensure the flatness of the cut surface of the steel bar.

[0034] Specifically, the top of the hydraulic shear 315 is equipped with a clamping plate 316, which corresponds to the position of the hydraulic shear 315. The clamping plate 316 is made of rubber and clamps the top of the steel bar to be cut to prevent the steel bar head from being thrown off by the force during the cutting moment and causing injury to the operator.

[0035] Working principle: First, the crane places the cutting mechanism next to the pile foundation via the lifting ring 2. Then, the crank handle 304 is rotated to move the first threaded rod 301 within the base 1, adjusting the height and balance of the base 1. The movable ball 302 allows the angle of the support leg 303 to change within a certain range, making the support more stable when used in the foundation pit. The level 307 can check whether the cutting mechanism is level, ensuring that the elevation of the rebar head is consistent after cutting. Next, the motor 309 drives the second threaded rod 310 to rotate, causing the slide 312 to move left and right to adjust its position relative to the rebar, facilitating cutting. Then, the telescopic rod 314 moves the hydraulic shear 315 towards the rebar. The clamping plate 316 clamps the rebar to be cut from above, preventing the rebar head from being thrown away by the force during cutting and causing injury to the operator. Finally, the hydraulic shear 315 works to cut the rebar. The hydraulic shear 315 can quickly complete the rebar cutting work in a short time, and the cutting force is uniform, ensuring the flatness of the rebar cut surface.

[0036] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
