Description

Technical Field

[0001] This utility model belongs to the field of coke pusher slide shoe technology, specifically relating to a novel upper slide shoe mechanism. Background Technology

[0002] The sliding shoe device is an important component of the coke pusher car in coke oven machinery. This device is connected to the pusher rod and drives the pusher rod through the pusher motor and pusher reducer to push the coke out of the carbonization chamber. Because the carbonization chamber is relatively long, and the pusher rod is also long during the pushing process, a sliding shoe device is designed to prevent the pusher rod from deflecting downwards and to reduce the pressure of the pusher head on the bottom of the carbonization chamber.

[0003] Currently, in order to improve the service life of existing coke pusher slides, wear-resistant sleeves are usually installed at the mounting slots. The wear-resistant sleeves reduce the wear of the connecting pin on the upper box of the slide. However, the traditional method of installing the wear-resistant sleeve on the coke pusher slide is simply to fix it with bolts, without a good positioning structure. At the same time, with long-term use, the end of the bolt will also experience significant wear between it and the upper box of the slide, thus reducing the overall service life of the slide. Utility Model Content

[0004] The purpose of this utility model is to provide a novel upper mechanism for the sliding shoe, which aims to solve the problem that in the existing coke pusher sliding shoe, in order to improve the service life of the sliding shoe, a wear-resistant sleeve is usually installed at the mounting groove to reduce the wear of the connecting pin on the upper box of the sliding shoe. However, the traditional installation method of the wear-resistant sleeve on the coke pusher sliding shoe is simply fixed by bolts, without a good positioning structure. At the same time, with long-term use, the end of the bolt will also generate a lot of wear between it and the upper box of the sliding shoe, thereby reducing the overall service life of the sliding shoe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel upper mechanism for a skate, comprising an upper box body for the skate, mounting grooves being provided on both outer walls of the upper box body, wear-resistant sleeves being provided on the inner side of the mounting grooves, four threaded holes being provided on one side of the wear-resistant sleeves, four fixing bolts being threaded through the outer walls of both outer walls of the upper box body for the skate, four positioning protrusions being connected to the outer wall of the wear-resistant sleeves, and four positioning grooves being provided on the inner side of the mounting grooves.

[0006] As a preferred embodiment of the upper mechanism of this novel ski boot, the four positioning protrusions and four positioning grooves are all arranged in a ring.

[0007] As a preferred embodiment of the upper mechanism of the new type of ski boot of this utility model, the positioning protrusions and the threaded holes are staggered.

[0008] As a preferred embodiment of the new upper mechanism of the ski boot of this utility model, the positioning groove and the positioning protrusion are sized to match.

[0009] As a preferred embodiment of the new upper mechanism of the skate shoe according to this utility model, the outer wall of the upper box of the skate shoe is provided with a wear-resistant ring, and the surface of the wear-resistant ring is circumferentially distributed with four through holes.

[0010] As a preferred embodiment of the upper mechanism of the new type of ski boot of this utility model, one end of the fixing bolt can pass through the wear-resistant ring through the through hole.

[0011] As a preferred embodiment of the upper mechanism of this novel ski boot, the wear-resistant ring is made of polytetrafluoroethylene.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting up positioning protrusions and positioning grooves, during the installation of the wear-resistant sleeve, the positioning protrusions distributed in a ring on the wear-resistant sleeve are embedded into the positioning grooves in the installation groove, and then the wear-resistant sleeve is fixed with fixing bolts. This can play the role of positioning the wear-resistant sleeve during installation, and also increase the contact area between the wear-resistant sleeve and the upper box of the slipper, thereby improving stability.

[0014] By using a wear-resistant ring, when fixing the wear-resistant sleeve with a fixing bolt, one end of the fixing bolt is passed through the through hole on the wear-resistant ring and then connected to the threaded hole on the wear-resistant sleeve. The wear-resistant ring can reduce the wear between the end of the fixing bolt and the upper box of the slipper. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a novel upper mechanism for a skate, comprising an upper box 1 for a skate, mounting grooves 2 on both outer walls of the upper box 1, a wear-resistant sleeve 3 on the inner side of the mounting grooves 2, four threaded holes 4 on one side of the wear-resistant sleeve 3, four fixing bolts 5 threaded through the outer walls of both outer walls of the upper box 1, four positioning protrusions 6 connected to the outer wall of the wear-resistant sleeve 3, and four positioning grooves 7 on the inner side of the mounting grooves 2;

[0023] It should be noted that the existing slipper is connected to the coke pusher rod, and the coke pusher rod is driven by the coke pusher motor and the coke pusher reducer to push the coke out of the carbonization chamber.

[0024] Preferably, the four positioning protrusions 6 and the four positioning grooves 7 are arranged in a ring, the positioning protrusions 6 and the threaded holes 4 are staggered, and the dimensions of the positioning grooves 7 and the positioning protrusions 6 are matched.

[0025] In practical use, by setting the positioning protrusions 6 and positioning grooves 7, during the installation of the wear-resistant sleeve 3, the positioning protrusions 6 distributed in a ring on the wear-resistant sleeve 3 are embedded into the positioning grooves 7 in the installation groove 2, and then the wear-resistant sleeve 3 is fixed by the fixing bolts 5. This can play the role of positioning the wear-resistant sleeve 3 and also increase the contact area between the wear-resistant sleeve 3 and the installation point of the upper box 1 of the slipper, thereby improving stability.

[0026] Preferably, the outer wall of the upper box 1 of the slipper is provided with a wear-resistant ring 8, and the surface of the wear-resistant ring 8 has four through holes 9 distributed in a ring. One end of the fixing bolt 5 can pass through the through holes 9 to penetrate the wear-resistant ring 8. The material of the wear-resistant ring 8 is polytetrafluoroethylene.

[0027] In practical use, by setting the wear-resistant ring 8, when fixing the wear-resistant sleeve 3 with the fixing bolt 5, one end of the fixing bolt 5 is passed through the through hole 9 on the wear-resistant ring 8 and then connected to the threaded hole 4 on the wear-resistant sleeve 3. The wear-resistant ring 8 can reduce the wear between the end of the fixing bolt 5 and the upper box 1 of the slipper.

[0028] Working principle: First, during the installation of the wear-resistant sleeve 3, the positioning protrusions 6 distributed in a ring on the wear-resistant sleeve 3 are embedded into the positioning grooves 7 in the installation groove 2, which can play the role of positioning the wear-resistant sleeve 3 and increase the contact area between the wear-resistant sleeve 3 and the upper box 1 of the slipper, thereby improving stability. Then, when fixing the wear-resistant sleeve 3 with the fixing bolt 5, one end of the fixing bolt 5 is passed through the through hole 9 on the wear-resistant ring 8 and then connected to the threaded hole 4 on the wear-resistant sleeve 3. The wear-resistant ring 8 can reduce the wear between the end of the fixing bolt 5 and the upper box 1 of the slipper.
