Abstract
The utility model discloses a hydraulic support and scraper chute adjusting and lengthening device, which relates to the technical field of fully-mechanized mining face supporting equipment. The utility model has the advantages that: according to the utility model, the extension bar is added between the hydraulic support pushing bar and the scraper chute to compensate the stroke of the pushing bar, so that the movable range between the hydraulic support and the chute is enlarged, the equipment transferring and equipment overhauling space in the last mining stage is greatly increased, the downtime is shortened, the production efficiency is improved, and the equipment maintenance cost is reduced.
Description
Technical Field
The utility model relates to the technical field of fully-mechanized mining face supporting equipment, in particular to a hydraulic support and scraper chute adjusting and lengthening device.
Background
The hydraulic support is fully mechanized coal face supporting equipment, and has the main function of supporting a coal face top plate and maintaining a safe working space. When the coal face enters the last mining stage and equipment needs to be transported or the coal face needs to be overhauled, the equipment cannot be transported or overhauling work cannot be enough overhauling space because the distance between the hydraulic support and the scraper conveyor chute is too short, and the existing practical requirements cannot be met.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a hydraulic support and scraper chute adjusting and lengthening device.
The utility model is realized by the following technical scheme:
the utility model provides a hydraulic support and scrape trigger chute regulation extension device, includes the extension bar body, is equipped with the public head of being connected with scrape trigger chute in the one end of extension bar body, and the other end is equipped with the female head of being connected with hydraulic support's push rod, public head be outwards convex circular arc type, female head be square.
The male head and the female head are respectively provided with a connecting hole, and the male head and the female head are respectively connected with a scraper chute and a pushing rod of the hydraulic support through pin shafts.
The section of the extension rod body is square.
The utility model has the advantages that: according to the utility model, the extension bar is added between the hydraulic support pushing bar and the scraper chute to compensate the stroke of the pushing bar, so that the movable range between the hydraulic support and the chute is enlarged, the equipment transferring and equipment overhauling space in the last mining stage is greatly increased, the downtime is shortened, the production efficiency is improved, and the equipment maintenance cost is reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a front view of the present utility model;
FIG. 3 is a cross-sectional view of the present utility model;
fig. 4 is a connecting structure diagram of the extension bar, the hydraulic support pushing bar and the scraper chute.
Detailed Description
As shown in fig. 1-4, the hydraulic support and scraper chute adjusting and lengthening device comprises a lengthening bar body 1, wherein one end of the lengthening bar body 1 is provided with a male head 2 for connecting a scraper chute 5, and the direction rotation is flexible when the scraper chute is designed into an arc structure for adjusting the frame, so that the frame adjusting operation is convenient;
in addition, one end is provided with a female head 3 and is used for being connected with a pushing rod 7 of the hydraulic support 6, the pushing rod is of a square structure, the two ends are large in stress area during the support adjustment operation, stress is concentrated, and the operation efficiency is improved.
The connecting holes 4 are formed in the two ends of the extension rod body 1 and are connected with the scraper chute and the hydraulic support pushing rod through the pin shafts, so that the extension rod is convenient to install and detach, and the working strength of workers is reduced.
The section of the extension bar body 1 is square.
According to the utility model, the hydraulic support is used for adjusting the rack extension bar, so that the equipment transferring and equipment maintenance space in the last mining stage is greatly increased, the downtime is shortened, the production efficiency is improved, and the equipment maintenance cost is reduced.
