Description

Technical Field

[0001] This utility model relates to the field of hydraulic shearing technology, and in particular to a multifunctional hydraulic shearing device. Background Technology

[0002] Hydraulic shears are widely used in road and railway accident rescue, earthquake disaster rescue, building collapse rescue, air and sea disaster rescue, and can cut vehicle components, metal structural pipes, irregular steel and plates.

[0003] Patent document CN221336834U discloses a hydraulic shear, including a main body. A placement groove is formed at the right end of the bottom of the main body, and a battery is placed inside the placement groove. A first rotating shaft is connected to the right end of the bottom of the placement groove, and a cover plate is connected to the surface of the first rotating shaft. A groove is formed on the top of the cover plate. A rectangular through hole is formed at the left end of the top of the main body, and a limiting groove is provided above the rectangular through hole. A push plate is slidably connected inside the limiting groove, the groove, and the rectangular through hole. A limiting plate is provided on the top of the push plate. A shearing mechanism is provided at the right end of the main body. This placement groove is used to store the battery. By sequentially inserting the push plate into the limiting groove, the rectangular through hole, and the groove, the cover plate is fixed to the left side of the placement groove, sealing the battery inside. This prevents damage to the battery in the placement groove when the hydraulic shear falls, thus improving the service life of the hydraulic shear. The push plate facilitates the removal and installation of the battery.

[0004] The shortcomings of existing technology are as follows: When cutting an object, the angle of the shear blade needs to be adjusted adaptively according to the posture of the object to be cut. The angle of the shear blade is adjusted by adjusting the angle of the main body. However, the handle is often fixed to the main body. As a result, the angle of the handle will also change when the angle of the shear blade is adjusted. It is impossible to ensure that the handle is at a comfortable grip angle. If the user holds the handle in an uncomfortable posture, it will accelerate arm fatigue, reduce durability, and make it difficult to work with the shearer for a long time. It may also lead to arm strain and injury. Fatigue and awkward posture will cause the operator's arm to tremble, making it difficult to accurately aim at the cutting target, which is not conducive to the efficient conduct of rescue work.

[0021] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figure 1-4 A multifunctional hydraulic shear includes a main body 1, an adjusting cylinder 2 rotatably connected to the main body 1, a handle fixedly connected to the adjusting cylinder 2, and a limiting component provided on the adjusting cylinder 2. A limiting hole 11 is opened on the peripheral side of the main body 1, and the limiting hole 11 cooperates with the limiting component to limit and fix the adjusting cylinder 2. A shearing component is also provided on the main body 1. In use, by adjusting the angle between the handle and the shearing component, both the shearing blade 14 can be at a suitable angle to cut the object, and the handle can also be at a suitable angle. The operator can independently adjust the relative angle between the handle and the shearing component according to the spatial posture of the object to be cut and the working environment. This design achieves bidirectional optimization: on the one hand, the spatial orientation of the shearing blade 14 can be precisely adjusted so that it is aligned with the target object at the best cutting angle, ensuring shearing efficiency and cut quality; on the other hand, the handle can be adjusted to the most ergonomic grip position without changing the angle of the shearing blade, so that the operator's arm and wrist are in a natural and relaxed state.

[0023] As a preferred technical solution of this embodiment, a plurality of limiting holes 11 are provided and distributed in a circumferential array along the main body 1. The limiting component includes a limiting pin 23 that is movably installed through the adjusting cylinder 2. One end of the limiting pin 23 is fixedly connected to a pull block 24, and the other end is movably inserted into the corresponding limiting hole 11. A spring 25 is fixedly connected between the pull block 24 and the adjusting cylinder 2. The spring 25 is movably sleeved on the outside of the limiting pin 23. The limiting pin 23 is adapted to the size of the limiting hole 11.

[0024] As a preferred technical solution of this embodiment, the main body 1 has a hollow cavity inside, and a shearing assembly is provided inside the hollow cavity. The shearing assembly includes a hydraulic rod 12 fixedly installed inside the hollow cavity. The telescopic end of the hydraulic rod 12 is hinged to two connecting rods 13. The ends of the two connecting rods 13 away from the hydraulic rod 12 are each hinged to a shearing blade 14. The two shearing blades 14 are hinged to the main body 1 through a hinge shaft 15. Specifically, the hydraulic rod 12 is driven to extend and retract by pressing a control button. When the hydraulic rod 12 extends, the telescopic end of the hydraulic rod 12 pushes the two shearing blades 14 to close in the middle through the connecting rods 13, so as to realize the shearing operation on the object located between the two shearing blades 14.

[0025] As a preferred technical solution in this embodiment, the handle consists of a first handle 21 and a second handle 22. The first handle 21 is provided with a control button for controlling the extension and retraction of the hydraulic rod 12. By integrating the control button onto the first handle 21, the operator can press the control button with their thumb while holding the first handle 21 to start the operation of the hydraulic rod 12. The arrangement of the first handle 21 and the second handle 22 allows the operator to hold the shear with both hands, improving the stability of the shear when using it.

[0026] As a preferred technical solution in this embodiment, a light lamp 16 is provided at one end of the main body 1 near the shearing blade 14. Specifically, in order to prevent the light lamp 16 from being damaged by collisions with external objects, a transparent protective cover can be provided on the outside of the light lamp 16, which will not affect the lighting effect of the light lamp 16 and can also protect the light lamp 16.

[0027] Working principle: When it is necessary to cut an object, the operator first observes the posture of the object to be cut, that is, what angle the shearing blade 14 needs to be at to facilitate cutting the object. Then, the angle between the shearing blade 14 and the handle is adjusted. By pulling the pull block 24 and overcoming the elastic force of the spring 25, the limiting pin 23 is disengaged from the limiting hole 11, releasing the limiting fixation of the adjusting cylinder 2. At this time, the adjusting cylinder 2 can be adjusted relative to the main body 1. Rotating the main body 1 drives the shearing blade 14 to adjust relative to the handle. When the two are at a suitable angle, the elastic force of the spring 25 drives the limiting pin 23 to move and insert it into the corresponding limiting hole 11, thereby limiting and fixing the adjusting cylinder 2 and the main body 1.

[0028] By adjusting the angle between the handle and the shear blade 14, it is possible to ensure that the shear blade 14 is at a suitable angle for cutting objects, and also to ensure that the handle is at a suitable angle, so that the operator can hold it in a comfortable posture. This avoids arm fatigue and reduced durability due to an uncomfortable grip posture, and also reduces the risk of arm strain and injury. It also improves the stability of the operator when holding the shears to cut objects, which is conducive to accurately aiming at the cutting target and facilitating efficient rescue work.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
