Description

Technical Field

[0001] The utility model relates to the technical field of chain link test tooling, in particular to a vertical chain link fatigue special tooling for mining. Background Art

[0002] The mining vertical chain link is an indispensable part of mining conveying equipment. Its function is to connect the mining chain end to end. The fatigue life of the mining vertical chain link is very important during use. Therefore, the fatigue life of the mining vertical chain link will be sampled before the mining vertical chain link is sold.

[0003] During the random inspection, a special tooling for mining chain fatigue will be used. At present, when performing fatigue testing on mining vertical link chains, when the pitch size is equal, the total length of the mining vertical link chains is greater than that of mining chains of the same specification. As a result, when performing fatigue testing on mining vertical link chains, the mining vertical link chains will interfere with the tooling. When this problem occurs, a larger specification chain is often used to grind the matching part with the mining vertical link chains and use it as a process ring to complete the fatigue testing of the mining vertical link chains. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the chain link used in the fatigue detection process of the mining vertical chain link is larger than the mining vertical chain link and needs to be ground at the matching part with the mining vertical chain link before use.

[0005] In order to achieve the above-mentioned purpose, the present application proposes a special tooling for fatigue of a vertical mining chain connecting ring, which is used to clamp and fix the vertical mining chain connecting ring during fatigue detection, wherein the vertical mining chain connecting ring is composed of a left half ring of a vertical mining chain connecting ring and a right half ring of a vertical mining chain connecting ring spliced ​​together, and the special tooling for fatigue of the vertical mining chain connecting ring includes: a tooling part, a vertical mining chain connecting ring installed between the two tooling parts, a chain link connecting the tooling part and the vertical mining chain connecting ring, and a fixing pin fixing the chain link and the tooling part.

[0006] The invention discloses a special tool for fatigue protection of a vertical chain link for mining, which embeds the annular portion of the vertical chain link for mining into the tool part by setting a second groove at the bottom end of the tool part, thereby avoiding interference between the vertical chain link for mining and the tool part.

[0007] Furthermore, after solving the problem of avoiding interference between the mining vertical chain ring and the tooling part, chain links of the same specifications as the mining vertical chain ring can be selected for connection, instead of selecting larger chain links and putting them into use as process rings after grinding.

[0008] The tooling part includes a fixing part and an installation part. The fixing part is provided with a first groove for clamping the chain link. The bottom end of the groove is provided with a second groove for positioning the mining vertical connecting chain link. Pin holes for installing fixing pins are provided on the left and right end surfaces of the fixing part.

[0009] Furthermore, in order to more conveniently fix and install the chain link, the first groove passes through the front and rear end surfaces of the fixing portion, and the bottom shape of the first groove is a U-shaped groove.

[0010] Furthermore, in order to more conveniently and accurately fix the tooling part, grooves for connecting to the fatigue machine are provided on the left and right end surfaces of the mounting part.

[0011] Furthermore, in order to better install and fix the vertical mining link, one end of the chain link is connected to the vertical mining link, and the other end is clamped on the arc bottom of the groove.

[0012] Furthermore, in order to better fix the position of the chain link and prevent it from shifting during fatigue detection, a groove is formed on the side of the fixing pin that contacts the chain link during installation.

[0013] The beneficial effects of this application are:

[0014] 1. The present application discloses a special tooling for fatigue of a vertical chain link for mining, which embeds the annular portion of the vertical chain link for mining into the tooling portion by setting a second groove at the bottom end of the tooling portion, thereby avoiding interference between the vertical chain link for mining and the tooling during use.

[0015] 2. The invention relates to a special tool for fatigue of a vertical linking link for mining. After solving the problem of avoiding interference between the vertical linking link for mining and the tooling part, a mining chain of the same specification as the vertical linking link for mining can be directly used as a process ring without grinding, thus saving test preparation time and cost.

[0029] The following will be combined with the attached Figures 1 to 7 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figures 1 to 3 The present application illustrates a special tooling for fatigue of a vertical mining chain link, which includes: a tooling part 1, a vertical mining chain link 2 installed between two tooling parts 1, a chain link 3 connecting the tooling part 1 and the vertical mining chain link 2, and a fixing pin 4 fixing the chain link 3 and the tooling part 1.

[0031] In one embodiment of the present application, the tooling part 1 is used to clamp the vertical mining link 2 , one end of the chain link 3 passes through the vertical mining link 2 , and the other end is installed on the tooling part 1 through a fixing pin 4 .

[0032] In the prior art, when fatigue testing is performed on the mining vertical chain connecting ring 2, a chain link 3 with the same pitch size as the mining vertical chain connecting ring 2 is usually selected as a process ring. However, since the mining vertical chain connecting ring 2 with the same pitch size is usually longer than the chain link 3 with the same specification, the mining vertical chain connecting ring 2 will interfere with the tooling during use. Therefore, it is necessary to reselect a larger chain to cooperate with the mining vertical chain connecting ring 2, and the part where the chain cooperates with the mining vertical chain connecting ring 2 needs to be ground before it can be put into use as a process ring.

[0033] In this embodiment, the tooling part 1 includes a fixing part 11 and an installation part 12. Since a first groove 111 for clamping the chain link 3 is opened on the fixing part 11, a second groove 112 for positioning the mining vertical chain link 2 is opened on the bottom end of the first groove 111, and pin holes 113 for installing the fixing pin 4 are opened on the left and right end surfaces of the fixing part 11, the annular part of the mining vertical chain link 2 can be embedded in the tooling part 1 by setting the second groove 112 at the bottom end of the tooling part 1, thereby avoiding interference between the mining vertical chain link 2 and the tooling part 1.

[0034] Furthermore, after solving the problem of avoiding interference between the mining vertical chain link 2 and the tooling part 1, a chain link 3 of the same specification as the mining vertical chain link 2 can be selected for connection, without selecting a larger chain link 3 for use as a process ring after grinding.

[0035] Furthermore, the first groove 111 passes through the front and rear end surfaces of the fixing portion 11, so that the chain link 3 can be more conveniently installed on the fixing portion 11, and the bottom shape of the first groove 111 is a U-shaped groove, which can better make the first groove 111 fit the circular ring part of the chain link 3 for easy installation.

[0036] Furthermore, grooves for connecting to the fatigue machine are provided on the left and right end surfaces of the mounting portion 12. The tooling portion 1 can be more accurately mounted at the position specified by the fatigue machine through the grooves on both sides, laying the foundation for the subsequent setting of the upper and lower fatigue load limits required by the standard.

[0037] Furthermore, the mining vertical chain ring 2 is composed of a left half ring 21 of the mining vertical chain ring and a right half ring 22 of the mining vertical chain ring, each step of the left half ring 21 of the mining vertical chain ring and the right half ring 22 of the mining vertical chain ring is provided with a semicircular hole. After the two half rings are spliced ​​together, the two semicircular holes can be combined into a circular hole. At this time, by installing two pins in the circular hole, the two half rings can be fixed into a mining vertical chain ring 2.

[0038] Furthermore, one end of the chain link 3 is connected to the mining vertical link 2 , and the other end is clamped on the arc-shaped bottom of the first groove 111 .

[0039] Furthermore, during the installation process, a groove is formed on the side of the fixing pin 4 that contacts the chain link 3. The groove limits the position of the chain link 3 and prevents errors in the detection data caused by the unstable position of the chain link 3 during fatigue detection.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
