Description

Technical Field

[0001] The utility model relates to the field of hardware tools for power plants, specifically a vibrating hammer assembly for coal chutes. Background Art

[0002] During the power generation process of power plant units, the coal feeder is an important pre-supply device and a prerequisite for ensuring the continuous operation of the units. Due to the certain adhesiveness of pulverized coal, the coal chute of the coal feeder is very prone to coal blockage accidents, and it is relatively difficult to dredge. During the dredging process, workers usually use a hammer to vibrate the coal chute from the outside. Frequent hitting can easily cause the hammer head to loosen and fall off, and even lead to personal injury accidents. Therefore, it is necessary to frequently lock the hammer head during the hammering process, and usually two people are required for the locking operation. One person is responsible for supporting the hammer body, and the other person is responsible for the locking work, so the operation is relatively cumbersome. On the other hand, due to the need for standardized management in the plant area to reset tools after use, and the hammer body needs to be carried during the dredging operation. Since the hammer body is relatively heavy, it is very inconvenient to carry. In view of this, a vibrating hammer assembly for coal chutes is proposed. Summary of the Invention

Specific implementation manners

[0023] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the present utility model rather than to limit the scope of the present utility model. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0024] In a specific embodiment, a coal chute vibrating hammer assembly is provided, including a moving frame 1 and a hammer body 2. The moving frame 1 includes a vertical frame 1.1 and a placing frame 1.2. In this example, the moving frame 1 is welded by structural steel, such as square tubes, angle steels or round tubes, etc. Among them, the placing frame 1.2 is connected to one side of the bottom of the vertical frame 1.1. A fixed leg frame 1.3 is provided at the end of the placing frame 1.2 away from the vertical frame 1.1, and a caster 1.6 is provided at the bottom of the vertical frame 1.1. When the moving frame 1 is inclined, the fixed leg frame 1.3 will be lifted, and the whole assembly can be walked by pulling the vertical frame 1.1, but when the hammer body is placed on it, the hammer body can be pulled to move, thereby facilitating the carrying of the hammer body. In addition, when the vertical frame 1.1 is placed vertically, the fixed leg frame 1.3 and the caster 1.6 constitute the support structure of the moving frame 1, realizing the vertical placement of the moving frame 1.

[0025] In this example, a hammer head plate 1.4 is provided on the top of the placing frame 1.2, and a through hole 1.41 is opened at the central position; a limiting plate 1.5 is provided at the bottom of the placing frame 1.2, and a notch 1.51 is provided at the top of the limiting plate 1.5 and is correspondingly arranged with the through hole 1.41;

[0026] In this example, the hammer body 2 includes a hammer handle 2.1 and a hammer head 2.2. Among them, the hammer handle 2.1 is a hollow tube. At one end of the hammer handle 2.1, there is a tension notch 2.11. At the rear end of the tension notch 2.11, there is a limit ring 2.3. The hammer head 2.2 is installed on the periphery of the tension notch 2.11, and the rear end of the hammer head 2.2 abuts against the limit ring 2.3. It also includes a pull rod 2.4. One end of the pull rod 2.4 is provided with a tapered head 2.41. Among them, the large diameter end of the tapered head 2.41 is set into a polygonal structure. The pull rod 2.4 penetrates through the hammer handle 2.1 and the tapered head 2.41 is inserted into the end of the tension notch 2.11. The end of the pull rod 2.4 without the tapered head 2.41 extends to the tail end of the hammer handle 2.1, and a nut 2.5 is arranged on the pull rod 2.4. When the hammer body is installed, by screwing the nut 2.5 and restricting the rotation of the pull rod 2.4, the nut 2.5 and the pull rod 2.4 can form a thread pair. By expanding the tension notch 2.11 with the tapered head 2.41, the outer diameter of this section of the hammer handle 2.1 increases. At the same time, the hammer head approaches the limit ring 2.3 until it abuts, so as to realize the tight fit of the holes of the hammer handle 2.1 and the hammer head 2.2. To make the nut 2.5 and the rear end of the hammer handle 2.1 more stable, the nut 2.5 is a flange nut, and the flange end can abut against the end of the hammer handle 2.1 to make its fixation more stable.

[0027] Since the hammer head needs to be continuously locked during use to ensure safety, in this application, to realize single-person locking operation,

[0028] When locking, place the hammer head 2.2 on the top of the hammer head plate 1.4, and the polygonal structure at the large diameter end of the tapered head 2.41 can be inserted into the notch 1.51 for rotation restriction. At this time, step on the fixed leg frame 1.3 with one foot, and at the same time hold the upright frame 1.1 by hand to fix it. At this time, a single operator can screw the nut 2.5 to expand the tension notch 2.11 with the tapered head 2.41, so that the diameter of this end of the hammer handle 2.1 increases, thereby realizing single-person locking of the hammer head and improving the convenience of use.

[0029] On this basis, the top of the hammer head plate 1.4 is recessed downward. In this example, the hammer head plate 1.4 adopts a sheet metal bending structure and is welded to the top of the placement frame 1.2, together with the placement frame 1.2 to form a recessed placement area, so as to be able to accommodate the hammer head and prevent it from falling off when the moving frame 1 moves with the hammer head.

[0030] Similarly, to realize the fixation of the hammer head, in another way, to prevent the hammer head from sliding on the hammer head plate 1.4, the hammer head can be placed in the through hole 1.41. In addition, a magnet is arranged on the hammer head plate 1.4, and the hammer head can be fixed to a certain extent by the adsorption of the magnet.

[0031] The fixation of the hammer head is achieved as above. Similarly, to fix the hammer handle, it further includes that one end of the rubber buckle 3 is fixed on the vertical frame 1.1, and the other end is provided with an opening. The hammer handle 2.1 can be clamped in the opening. During loading and unloading, the fixation of the hammer handle 2.1 is realized through the expansion and contraction of the opening of the rubber buckle 3.

[0032] In addition, it can be seen that the nut 2.5 is screwed by a wrench. To achieve a large range of screwing of the wrench, when the hammer body 2 is placed on the moving frame 1, the height of the hammer handle 2.1 is higher than that of the vertical frame 1.1. Therefore, it can avoid the interference of the vertical frame 1.1 on the wrench and improve the convenience of use.

[0033] In addition, to facilitate the carrying of the wrench, a position for placing the wrench is provided on the moving frame 1 or the vertical frame 1.1, such as a hook, a buckle, or a placement box, etc.

[0034] Inspired by the ideal embodiments of the present invention as described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
