Description

Technical Field

[0001] This utility model belongs to the technical field of coal pen forming impactor equipment, specifically relating to a hammer block fixing device for a forming impactor. Background Technology

[0002] In the field of coal testing, the Oya expansion degree measurement is an important indicator for evaluating the caking properties of coal. A forming impactor is used to press coal powder into a standard coal pen, and the impact force is applied to the coal powder by the free-fall motion of a heavy hammer. A traditional forming impactor structure includes a vertical guide rail, a liftable hammer, a bottom impact rod, and a guide plate.

[0003] In practice, there are safety hazards. When it is necessary to replace worn striking rods or clean guide plates, the operator needs to manually lift the hammer block to a high position and temporarily fix it. This relies on manually pulling the rope suspending the hammer block for fixation, but there are drawbacks. First, the rope is prone to slipping, unhooking, or breaking, and the hammer block is prone to sudden free fall. The fixing process requires the hand to be close to the bottom of the hammer block, and if it falls, it will directly injure the fingers. Moreover, each maintenance requires repeatedly binding the rope, which is time-consuming and difficult to operate with one hand. Therefore, a hammer block fixing device for a molded striking device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for the hammer block of a shaped impactor, which has the function of fixing the hammer block of the shaped impactor and solves the problem of the existing technology where the manual lifting of the hammer block relies on manually pulling the rope suspending the hammer block for fixing.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-2As shown, a hammer block fixing device for a forming impactor includes a mounting side plate 1, which serves as the device base and is fixed to the inner wall of the forming impactor frame to provide overall stability. Two support plates 2 are provided on the mounting side plate 1, vertically mounted to the side plate for support and load-bearing. Each support plate 2 has a slot 3, a channel formed in the support plate 2, within which a mounting seat 4 is provided. Two mounting seats 4 are arranged opposite each other. A support shaft 6 is provided on the front side of each mounting seat 4, temporarily holding the hammer block 9. The support shaft 6 is horizontally mounted on the front side of the mounting seat 4. When the two mounting seats 4 are pushed into place, the support shaft 6 is positioned directly below the hammer block 9, supporting and bearing the hammer block 9 in its raised position.

[0021] The support shaft 6 provides a sturdy and reliable physical support surface, and the pull rope prevents the hammer block 9 from accidentally falling due to gravity. The metal support shaft 6 provides strong bending strength and can stably bear the load of the hammer block 9. The position of the support shaft 6 determines the height at which the hammer block 9 is supported. The front end of the support shaft 6 is provided with an insertion pin 7, and the front side of the mounting base 4 is provided with a pin hole 8. The pin hole 8 is opened in the side wall of the hammer block 9 and is clearance-fitted with the insertion pin 7. After the mounting base 4 is pushed into place, the insertion pin 7 is inserted into the pin hole 8 of the opposite mounting base 4 to achieve fixation. After the insertion pin 7 enters the pin hole 8, a rigid connection is formed, locking the two mounting bases 4 together.

[0022] The specific design of the aforementioned key components will be discussed in detail below:

[0023] The mounting side plate 1 is bolted or welded to the inner wall of the forming impactor frame. Bolting facilitates disassembly and adjustment, while welding provides a permanent and secure connection, adapting to different needs.

[0024] The mounting base 4 is a cuboid slider, and the shape of the slot 3 matches the cross-section of the mounting base 4 to form a sliding pair. The mounting base 4 supports the support shaft 6 and, through the support shaft 6, supports the weight of the hammer block 9. The mounting base 4 can slide within the slot 3 to achieve the operations of pushing and fixing and pulling out and releasing. The mounting base 4 integrates key components such as the support shaft 6, the insertion pin 7, and the handle 5 into a movable unit. The matching of the mounting base 4 with the slot 3 ensures smooth and reliable sliding. When it is not necessary to fix the hammer block 9, the mounting base 4 can be removed without affecting the coal powder impact molding.

[0025] A handle 5 is provided on the rear side of the mounting base 4. The handle 5 is for the operator to grip and pull, allowing the operator to easily push or pull the mounting base 4 from a safe distance without having to put their hands into the danger zone under the hammer block 9 to complete the fixing or releasing action of the hammer block 9. It provides a point of force application and is convenient to operate. Compared with a pull rope, operating the handle 5 is generally safer and simpler.

[0026] Hammer block 9 is placed on the support shaft 6. A pull ring is located on the top of hammer block 9; this pull ring is a sturdy metal ring fixed to the top of hammer block 9 and serves as the direct connection point for the lifting mechanism, facilitating connection to hooks, rope ends, or other lifting devices. A pull line is connected to the top of hammer block 9. The pull ring and pull line are part of the original lifting mechanism of the forming impactor. The pull line can be a rope, wire rope, or chain. One end of the pull line is connected to the pull ring on the top of hammer block 9, and the other end is held by the operator or connected to a winch mechanism. After hammer block 9 is lifted to its highest position, in the traditional method, the operator needs to pull the pull line forcefully and temporarily fix it by winding, knotting, or hooking it to a temporary point to maintain hammer block 9 at a high position for maintenance. This device replaces this dangerous and unreliable operation. The pull line is responsible for lifting hammer block 9 through the pull ring. Once hammer block 9 is lifted to its highest position by the pull line, the operator no longer needs to rely on the pull line to temporarily fix hammer block 9. The operator can safely operate this fixing device, allowing the support shaft 6 to support the hammer 9 and lock it with the insertion pin 7. Once it is reliably locked in place, the operator can completely release the pull line. At this time, the weight of the hammer 9 is entirely borne by the support shaft 6, and the pull line is no longer under force, eliminating the risk of falling due to pull line failure.

[0027] The forming impactor and hammer block 9 are existing technology products, and their structures will not be described in detail.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
