Description

Technical Field

[0001] This utility model relates to the field of hydraulic support column protection technology, and in particular to a protective sleeve for sliding support columns. Background Technology

[0002] In mining, construction, and other fields, sliding supports serve as crucial support equipment. Their columns play a key role in supporting and lifting during operation, and sliding supports utilize hydraulic columns. However, sliding supports typically operate in harsh environments, where the column surface is susceptible to impacts from ore, dust erosion, sewage immersion, and mechanical wear. Over time, the anti-rust coating on the column surface will be damaged, leading to corrosion. This not only reduces the structural strength of the column, affecting the support stability and service life of the sliding support, but may also cause safety accidents. Currently, the protective measures for sliding support columns on the market are relatively simple, mostly using ordinary plastic or rubber sleeves. However, these protective sleeves are either insufficiently strong to effectively resist ore impacts, have poor sealing properties, allowing dust and sewage to easily enter the sleeve and come into contact with the column, or cannot move with the column.

[0003] Based on this, the present invention designs a protective sleeve for the sliding support column to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and achieve the above-mentioned functions, this utility model provides a protective sleeve for the sliding support column.

[0005] This utility model is achieved through the following technical solution: A protective sleeve for a sliding support column includes an outer sleeve fixed to the bottom plate of the sliding support and an inner sleeve fixed to the top plate of the sliding support. The telescopic column is located inside the two sleeves and its upper and lower ends are fixedly connected to the top plate and the bottom plate, respectively. The outer sleeve has a cavity with an opening at the top, and the inner sleeve is inserted into the cavity of the outer sleeve from above. A sealing ring is provided on the outer sleeve at the top of the cavity. The cross-section of the sealing ring is in the shape of the number "1". It is engaged with the vertical ring groove. The upper part of the sealing ring is provided with a locking protrusion, which is engaged with the horizontal ring groove of the outer sleeve.

[0006] Furthermore, a top support is welded to the top of the inner sleeve, and a bottom support is welded to the bottom of the outer sleeve. Both the top support and the bottom support are provided with countersunk holes.

[0007] Furthermore, the outer wall of the outer sleeve is provided with several rows of anti-collision rings, which are made of neoprene rubber.

[0008] Furthermore, the sealing ring is hollow and has an opening at the protrusion, and the sealing ring is connected to the outer sleeve with adhesive at the tight fit.

[0009] Furthermore, when the telescopic column reaches its uppermost position, the bottom end of the inner sleeve is still lower than the bottom end of the vertical ring groove; when the telescopic column reaches its lowermost position, the bottom of the inner sleeve does not contact the bottom of the cavity.

[0010] Furthermore, the sealing ring is interference-fitted with the inner sleeve, and the inner side of the sealing ring is compressed by it.

[0011] Furthermore, both the inner and outer sleeves are made of stainless steel.

[0012] The beneficial effects of this utility model are: This utility model can completely enclose the telescopic column, and the components connected to the telescopic column at the top and bottom are fixedly connected, that is, they move up and down together with the telescopic column to fully ensure the sealing performance; and the "1"-shaped sealing ring is used for easy disassembly and assembly; the inner and outer sleeves are inserted and linked with the telescopic column to seal at any time.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] like Figures 1 to 3 As shown, this utility model includes an outer sleeve 2 fixed on the base plate 6 of the sliding support and an inner sleeve 1 fixed on the top plate 601 of the sliding support. The telescopic column 5 is located inside the two and its upper and lower ends are fixedly connected to the top plate 601 and the base plate 6, respectively. The outer sleeve 2 is provided with a cavity 203 with an opening at the top, and the inner sleeve 1 is inserted into the cavity 203 of the outer sleeve 2 from above. A sealing ring 4 is provided on the outer sleeve 2 at the top of the cavity 203. The cross-section of the sealing ring 4 is in the shape of the number "1". It is engaged with the vertical ring groove 3. The upper part of the sealing ring 4 is provided with a locking protrusion 401. The locking protrusion 401 is engaged with the horizontal ring groove 301 of the outer sleeve 2 to prevent it from falling off. At the same time, it is convenient to install the ring, that is, it can be inserted by simply using a flathead screwdriver along the edge.

[0017] The top of the inner sleeve 1 is welded with a top support 101, and the bottom of the outer sleeve 2 is welded with a bottom support 201. Both the top support 101 and the bottom support 201 are provided with countersunk holes for fixing.

[0018] The outer sleeve 2 is provided with several rows of anti-collision rings 202. The anti-collision rings 202 are made of neoprene rubber, which can effectively reduce the impact buffering force and has a low cost. The adhesive installation method is also convenient.

[0019] The sealing ring 4 is hollow and easily deformed, and has an opening at the snap protrusion 401. The sealing ring 4 and the outer sleeve 2 are connected by adhesive at the tight fit, and the snap-fit ​​and adhesive method further ensures its stability.

[0020] When the telescopic column 5 reaches its uppermost position, the bottom end of the inner sleeve 1 is still lower than the bottom end of the vertical ring groove 3 to prevent the edge from getting stuck; when the telescopic column 5 reaches its lowermost position, the bottom of the inner sleeve 1 does not contact the bottom of the cavity 203.

[0021] The sealing ring 4 is press-fitted with the inner sleeve 1, and the inner side of the sealing ring 4 is compressed by it to prevent dust from entering. Of course, those skilled in the art will know that the base plate 6 can be perforated to connect the hydraulic pipe to other locations, or the control device for controlling the telescopic column 5 can be integrated into the sleeve so as not to hinder the extension and retraction of the sleeve, or the bottom of the outer sleeve 2 can be perforated as a channel for placing the oil pipe.

[0022] Both the inner sleeve 1 and the outer sleeve 2 are made of stainless steel.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
