Description

Technical Field

[0001] This utility model belongs to the technical field of sample preparation for packing and tamping in experimental coke ovens, specifically relating to a test coke oven tamping device with measurable height. Background Technology

[0002] During the sample preparation process of the bottom-loading test coke oven, the coal sample needs to be compacted to a predetermined density before being loaded into the box, and the height of the coal plane after loading should be kept at a specific distance from the top of the coal box.

[0003] Existing technologies often employ a step-by-step tamping measurement method: the tamping hammer head has a 15cm×15cm square planar structure. Due to its size limitation, it can only cover 1 / 4 of the coal box area at a time, requiring at least 4 sectional tamping operations on the coal box. Moreover, after each sectional tamping, a ruler tool needs to be replaced to measure the height separately. Due to the angle error and uneven coal surface, the single measurement error is large. In about 60% of the working conditions, tamping needs to be repeated 2-3 times to reach the target height, which leads to a longer single box loading time.

[0004] Furthermore, the alternating operation of tamping and measurement causes process interruptions, affecting the consistency of coke quality. Operators frequently need to approach the high-temperature furnace opening to change tools, increasing the risk of burns. In summary, there is an urgent need for an integrated device that can simultaneously complete tamping and height measurement to solve the problems of process fragmentation, low efficiency, and insufficient accuracy. Therefore, a test coke oven tamping device capable of measuring height is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a test coke oven tamping device that can measure the height of the test coke oven. This device solves the problem that in the prior art, after zonal tamping, it is necessary to replace the ruler tool to measure the height separately, resulting in large errors in a single measurement.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a test coke oven tamping device that can measure height, including a tamping hammer head, a tamping rod connected to the top of the tamping hammer head, a ball head provided at the end of the tamping rod, and a scale provided on the tamping rod.

[0007] Preferably, the vibratory hammer head is made of high-strength wear-resistant alloy steel with a surface nitriding hardening treatment.

[0008] Preferably, the vibrating rod is a cylindrical stainless steel rod with an anti-corrosion coating on its surface.

[0009] Preferably, the scale is laser-engraved on the side wall of the vibratory rod, and the scale unit is millimeters or centimeters.

[0010] Preferably, it also includes a scale ring that is slidably sleeved on the vibrating rod, and the side wall of the scale ring is provided with a reading groove that matches the scale and a locking screw.

[0011] Preferably, the vibratory hammer head and the vibratory rod are connected by threads, and an anti-loosening nut is provided at the connection.

[0012] Preferably, the bottom of the vibratory hammer head is a slightly convex curved surface, and the edge of the vibratory hammer head is provided with a chamfered structure.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model reads the compaction height of the coal in real time when vibrating coke oven coal, realizing the integrated operation of tamping and measurement. During the continuous tamping process, the amount of coal sinking can be directly observed, and the tamping force and frequency can be dynamically adjusted to avoid the process interruption caused by traditional step-by-step measurement.

[0015] 2. This utility model has the function of measuring the height of the experimental coke oven tamping, which solves the problem of large single measurement error in the prior art, which requires changing the caliper tool to measure the height separately after the sectional tamping.

[0019] 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.

[0020] 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.

[0021] Example 1, as Figure 1As shown, a height-measuring experimental coke oven tamping device includes a vibratory hammer head 1. The bottom surface of the vibratory hammer head 1 contacts the coal material. The bottom surface of the vibratory hammer head 1 is 35cm*15cm, solving the problem of uneven tamping in sections by 15cm×15cm planar hammer heads in the prior art, and increasing the coverage area of ​​a single tamping operation. A vibratory rod 2 is connected to the top of the vibratory hammer head 1, and the vibratory rod 2 transmits the impact force to the vibratory hammer head 1. A ball head 3 is provided at the end of the vibratory rod 2, which is a spherical handle at the end of the vibratory rod 2, providing a gripping surface, reducing operator hand fatigue, and improving continuous operation efficiency. A scale 4 is provided on the vibratory rod 2, located on the side wall of the vibratory rod 2, directly displaying the coal settling depth.

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

[0023] The vibratory hammer head 1 and the vibratory rod 2 are connected by threads, and an anti-loosening nut 5 is provided at the connection. The anti-loosening nut 5 locks the threaded connection between the vibratory hammer head 1 and the vibratory rod 2, resists high-frequency vibration, reduces the risk of loosening, extends the maintenance cycle, and prevents the hammer head from falling off and causing safety accidents, which complies with the OSHA vibratory tool safety standard.

[0024] The vibratory hammer head 1 is made of high-strength wear-resistant alloy steel with a surface nitriding hardening treatment. The high-strength alloy steel is 42CrMo, which has been treated with gas nitriding. The bottom of the vibratory hammer head 1 has a slightly convex curved surface, and the edge of the vibratory hammer head 1 has a chamfered structure. The radius of curvature of the slightly convex curved surface is R = 500mm, which is suitable for the plastic deformation characteristics of coal. The chamfered edge is 45° × 2mm to reduce edge stress concentration and prevent coal from sticking together. The slightly convex curved surface makes the impact force evenly distributed.

[0025] The vibrating rod 2 is a cylindrical stainless steel rod with an anti-corrosion coating. The stainless steel is SUS304 stainless steel with a hard chrome plating. The cylindrical rod has a diameter of Φ30mm and a length of 1.2-1.5m. It covers the depth of a standard coke oven coal box, and the hard chrome plating improves the corrosion resistance compared to the untreated rod.

[0026] The scale 4 is laser-engraved on the side wall of the vibratory rod 2, with units of millimeters or centimeters. Laser engraving on the side wall of the rod, using both millimeter and centimeter units, adapts to different precision requirements, enabling simultaneous tamping and measurement, shortening single-box operation time, and the laser-engraved scale 4 is resistant to coal powder friction. The initial scale 4 takes into account the thickness of the vibratory hammer head 1 and the height of the anti-loosening nut 5; the initial value of the scale 4 can be set according to actual conditions.

[0027] It also includes a scale ring 6 that is slidably fitted onto the vibrating rod 2. The side wall of the scale ring 6 is provided with a reading groove 7 that mates with the scale 4 and a locking screw 8. Sliding onto the vibrating rod 2, the scale 4 is aligned through the reading groove 7 and the position is fixed by the locking screw 8, so as to achieve accurate reading at eye level and preset target height.

[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.
