Abstract
The utility model relates to a repairing device applicable to U-shaped steel for coal mines. The repairing device comprises a base, a support frame and a hydraulic cylinder, wherein the support frame comprises stand columns and a top cover, the stand columns are vertically arranged at four corners of the base respectively, the top cover is horizontally arranged on the stand columns, and a through hole is formed in the surface of the top cover; the hydraulic cylinder penetrates through the through hole and is vertically matched with the top cover, and a piston rod of the hydraulic cylinder moves vertically downwards. By means of the repairing device, the maintenance efficiency of the U-shaped steel is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to production facility of coalmine, relates in particular to a kind of prosthetic device that is applicable to coal mine U-shaped steel.
Background technology
In coal production, in tunnel, need to use U-shaped steel to play a supporting role, the use amount of U-shaped steel is larger, at U-shaped steel, use after the long period, owing to being subject to the effect of tunnel inner wall pressure, can produce distortion, when serious, bending can occur, the U-shaped steel that therefore need to more renew the U-shaped steel of distortion.In prior art, for the U-shaped steel of distortion, often take the U-shaped steel more renewing to use; Or adopt prosthetic device to keep in repair the U-shaped steel of distortion.In prior art, exist maintenance cost high, the defect that maintenance efficiency is low.
Summary of the invention
For solving defect of the prior art, the utility model proposes a kind of prosthetic device that is applicable to coal mine U-shaped steel, comprise base, also comprise bracing frame and hydraulic jack; Support frame as described above comprises column and top cover; Totally four and be vertically arranged on respectively on four corners of base, described column; Described top cover is horizontally set on column, and described top cover surface arranges through hole; Described hydraulic jack vertically coordinates top cover to place through through hole, and the piston rod of hydraulic jack moves straight down.
Described column is four I-steel, and described top cover is the steel plate covering on four root posts.
Beneficial effect
Compared with prior art, the utility model, by bracing frame and hydraulic jack are set, makes the U-shaped steel damaging can be placed in device, the strength of utilizing hydraulic jack to move straight down, the U-shaped steel position that bending is damaged is repaired intact, has reduced production cost, has improved maintenance efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1. base, 2. column, 3. hydraulic jack, 4. top cover, 5. by-pass valve control, 6. piston rod.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in the figure, a kind of prosthetic device that is applicable to coal mine U-shaped steel of the utility model, comprises base 1, also comprises bracing frame and hydraulic jack 3; Bracing frame comprises column 2 and top cover 4; Column 2 is vertically arranged on respectively on four corners of base 1; Top cover 4 is horizontally set on column 2, and top cover surface arranges through hole; Hydraulic jack 3 vertically coordinates top cover 4 to place through through hole, and the piston rod 6 of hydraulic jack 3 moves straight down.Column 2 is four I-steel, and top cover 4 is the steel plates that cover on four root posts 2.
The base 1 of prosthetic device is prior art, and hydraulic jack 3 is also that existing equipment comprises piston rod 6.The I-steel that first vertically four appearance and sizes of welding are identical on four corners of base 1 is as column 2, and column 2 plays the effect of support hydraulic pressure oil cylinder 3 and top cover 4; Then on column 2, cover the steel plate of predetermined thickness as top cover 4, the central part of top cover 4 steel plates, with a gas cutting through hole out, can be fixed on top cover 4 by through hole hydraulic jack 3 in advance; The wherein outside by-pass valve control 5 of controlling hydraulic jack 3 of installing of side of at column 2.During use, the U-shaped steel damaging from the side of this prosthetic device be put into hydraulic jack 3 below, pass the space of two heel posts 2, be placed on the below of hydraulic jack 3 piston rods 6, the by-pass valve control 5 of manually opened hydraulic jack 3, piston rod 6 is moved downward, utilize the strength that piston rod 6 moves downward to repair intact at position to be repaired.The utility model design is succinct, and maintenance work efficiency is high, has reduced production cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
