[0024] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.
[0025] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.
[0026] In related technologies, the grab bucket device used in cyclone wells includes a grab bucket assembly, which includes a base and a grab bucket. The base is connected to a crane, and the crane controls the grab bucket assembly to enter the cyclone well for grabbing steel slag through two sets of lifting and opening / closing steel wire ropes (the grab bucket opens, and the descent and opening of the grab bucket are synchronized to the bottom of the cyclone well for grabbing steel slag). However, the steel slag water in the cyclone well will drive the grab bucket device to rotate under high-speed rotation, which will cause the steel wire rope to easily become entangled and damaged.
[0027] In response, this application proposes a grab bucket device 100 for vortex wells, such as... Figure 1 As shown, the grab bucket device 100 for a vortex well includes: a grab bucket assembly 20, which is adapted to extend into the vortex well 10 and includes a base 21 and a grab bucket connected to the base 21.
[0028] Understandably, the grab bucket can be opened or closed to grasp steel slag or other materials. In some implementations, the overhead crane can be connected to the grab bucket device 100 for the vortex well to control the grab bucket assembly 20 to enter the vortex well 10 for steel slag grabbing operations. The overhead crane can control the grab bucket to open or close through two sets of lifting and opening / closing wire ropes to grab the steel slag.
[0029] Among them, such as Figure 2 As shown, the inner wall of the vortex well 10 is provided with a first limiting member 31, such as... Figure 1 As shown, the base 21 is equipped with a second limiting member 32, and the first limiting member 31 and the second limiting member 32 are engaged in a circumferential upper limit cooperation in the vortex space 11. This ensures that the first limiting member 31 and the second limiting member 32 are engaged in a circumferential upper limit cooperation in the vortex space 11. Thus, when the crane controls the grab bucket assembly 20 to enter the vortex well 10 to grab slag through the lifting and opening / closing wire ropes, the grab bucket assembly 20 will not be pushed and rotated by the high-speed rotation of the slag water inside the vortex well 10, thereby avoiding the problem of wire rope entanglement and damage.
[0030] According to the embodiment of this application, the grab bucket device 100 for a vortex well is provided with a second limiting member 32 on the base 21 and a first limiting member 31 on the inner wall of the vortex well 10, so that the first limiting member 31 and the second limiting member 32 are in a circumferential upper limit engagement in the vortex space 11. In this way, when the crane controls the grab bucket assembly 20 to enter the vortex well 10 to grab steel slag by lifting and opening and closing two sets of steel wire ropes, the grab bucket assembly 20 will not be pushed by the high-speed rotation of the steel slag water in the vortex well 10 and thus rotate, thereby avoiding the problem of steel wire rope entanglement and damage.
[0031] In some embodiments, such as Figure 2 As shown, the first limiting member 31 is constructed as a limiting groove, as... Figure 1 As shown, the second limiting member 32 is constructed as a limiting arm, with one end of the limiting arm away from the base 21 inserted into the limiting groove.
[0032] Therefore, the first limiting member 31 and the second limiting member 32 can be matched by the insertion and matching of the limiting arm and the limiting groove. The setting of the limiting arm and the limiting groove is relatively simple, which helps to reduce the difficulty of setting. At the same time, the inner wall of the limiting groove can play a certain limiting role on the limiting arm, thereby enhancing the stability of the matching between the two.
[0033] In some embodiments, such as Figure 2 As shown, the limiting groove is open toward the swirling space 11.
[0034] This makes the slotting of the limiting groove easier to create, thus reducing the difficulty of slotting the limiting groove.
[0035] In some embodiments, the limiting groove extends in the depth direction of the swirling space 11, and the end of the limiting arm away from the base 21 slides in cooperation with the limiting groove in the depth direction of the swirling space 11.
[0036] This allows the limiting arm to extend into the limiting groove along the depth direction of the swirling space 11, and the limiting arm to slide along the depth direction of the swirling space 11, thereby ensuring the movement of the grab assembly 20 in the depth direction of the swirling space 11.
[0037] In some embodiments, such as Figure 1 As shown, the end of the limiting arm away from the base 21 is provided with a rotatable guide wheel 33, which is adapted to roll in the limiting groove.
[0038] Therefore, by setting the guide wheel 33, the sliding friction between the limiting arm and the bottom wall of the limiting groove is changed into rolling friction between the guide wheel 33 and the bottom wall of the limiting groove, which helps to reduce friction.
[0039] In some embodiments, such as Figure 1 As shown, the second limiting member 32 is located on the side of the base 21 away from the free end of the grab bucket.
[0040] Understandably, the free end of the grab bucket is used to grab steel slag, and the second limiting member 32 is installed on the side of the base 21 away from the free end of the grab bucket, which can prevent the second limiting member 32 from interfering with the grab bucket, thereby avoiding affecting the action of the grab bucket.
[0041] In some embodiments, such as Figure 1 As shown, there are multiple first limiting members 31 and multiple second limiting members 32. The multiple first limiting members 31 are spaced apart in the circumferential direction of the swirling space 11, and the multiple second limiting members 32 are arranged in a one-to-one correspondence with the multiple first limiting members 31.
[0042] Therefore, by setting multiple second limiting members 32 corresponding one-to-one with multiple first limiting members 31, the stability of the limiting cooperation between the first limiting members 31 and the second limiting members 32 in the circumferential direction of the swirling space 11 is enhanced. Moreover, if one of the first limiting members 31 and / or the second limiting member 32 is damaged, the limiting cooperation between the grab bucket and the inner wall of the swirling well 10 in the circumferential direction of the swirling space 11 can also be achieved through the limiting cooperation between the other second limiting members 32 and the first limiting members 31.
[0043] In some embodiments, such as Figure 1 As shown, the grab bucket device 100 for the vortex well also includes an elastic element 34, which is connected between the base 21 and the limiting arm, and is adapted to apply an elastic force to the limiting arm toward the limiting groove.
[0044] For example, the elastic element 34 can be a spring connected between the base 21 and the limiting arm. In this way, the elastic element 34 can be used to apply an elastic force to the fit between the limiting arm and the limiting groove. This reduces the impact that the grab may have on the limiting arm when it moves along the depth direction of the vortex well 10, thereby enhancing the stability of the limiting fit between the limiting arm and the limiting groove.
[0045] In some embodiments, such as Figure 1 As shown, the limiting arm and the base 21 are rotatably connected by a pin 35. When the limiting arm rotates relative to the base 21, the elastic element 34 is compressed or stretched.
[0046] Therefore, by setting the limiting arm to rotate relative to the base 21, if the bottom wall of the limiting groove is uneven and impacts the limiting arm when the grab moves along the depth direction of the vortex well 10, the limiting arm can rotate relative to the base 21, thereby reducing the impact force on the limiting arm during the movement of the grab up and down the vortex well 10, thus protecting the limiting arm and extending its service life. At the same time, when the limiting arm rotates relative to the base 21, the elastic element 34 is compressed or stretched. In this way, the deformation of the elastic element 34 can further reduce the impact that the grab may have on the limiting arm when it moves along the depth direction of the vortex well 10, thereby enhancing the stability of the limiting arm and the limiting groove's limiting fit.
[0047] In some embodiments, such as Figure 1 As shown, the elastic element 34 is located on the side of the limiting arm away from the grab bucket. This avoids interference between the elastic element 34 and the grab bucket, thereby reducing the difficulty of setting the elastic element 34.
[0048] In some embodiments, the limiting arm is provided with a first fixed fulcrum, and the base 21 is provided with a second fixed fulcrum. The first fixed fulcrum and the second fixed fulcrum are respectively located on both sides of the pin 35. One end of the elastic member 34 is connected to the first fixed fulcrum and the other end is connected to the second fixed fulcrum, that is, the elastic member 34 spans the pin.
[0049] In this way, the difficulty of setting the elastic element can be reduced by setting the first fixed fulcrum and the second fixed fulcrum, and it is beneficial to achieve the effect of compression or stretching of the elastic element 34 when the limiting arm rotates relative to the base 21.
