Description

Technical Field

[0001] This utility model relates to the field of hydraulic supports, and in particular to hydraulic supports for heavy equipment in coal mines. Background Technology

[0002] In coal seams, the working conditions of coal mining machines during coal cutting are complex and the environment is quite harsh, which can easily lead to uneven stress on hydraulic supports and damage to support components. Regular maintenance of the supports is required to ensure the normal operation of the equipment. However, hydraulic supports are tall, heavy, and difficult to maintain.

[0003] When repairing equipment, new hydraulic supports are needed to support the roadway to prevent accidents. However, the internal environment of the coal mine is complex. The top wall of the mine roadway may be sloping, and there may be a risk of collapse on the side of the mine. Existing supports are difficult to adjust the support angle and have poor support stability.

[0004] Therefore, those skilled in the art have provided hydraulic supports for heavy equipment in coal mines to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a hydraulic support for heavy equipment in coal mines, wherein the side support mechanism can support the side wall of the mine when the main body is deployed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic support for heavy equipment in coal mines, comprising a main body, a base fixedly mounted on the lower end face of the main body, side support mechanisms rotatably mounted on both sides of the main body, a protective box including a sliding cylinder fixedly mounted on the inner walls of both sides of the protective box, a rotating motor fixedly mounted on the bottom surface of the protective box, a moving rod slidably mounted on both sides inside the sliding cylinder, an installation box fixedly mounted on the upper end face of the sliding cylinder, a second electric push rod fixedly mounted on the bottom surface of the installation box, and a support platform fixedly mounted on the upper end face of the second electric push rod;

[0007] The upper surface of the support platform is hinged with rotating plates on both sides, and telescopic rods are rotatably mounted on both sides of the upper surface of the support platform. A steering block is fixedly mounted on one side of the lower surface of each of the two rotating plates. The side support mechanism includes a rotating disk. A mounting plate is fixedly mounted on one side of the rotating disk. A second protective plate is threadedly mounted on one side of the mounting plate. Two mounting rods are threadedly mounted on the other side of the second protective plate. Three first protective plates are threadedly mounted on one side of each of the two mounting rods. Multiple second connecting screws are threadedly fitted on the other side of each of the two mounting rods.

[0008] Furthermore, a first electric push rod is fixedly provided on both the front and rear ends of the main body, and two anti-slip pads are fixedly provided on the lower end surfaces of the two first electric push rods.

[0009] Furthermore, a movable seat is fixedly provided on the lower end face of the base, and rotating wheels are rotatably provided on both sides of the movable seat.

[0010] Furthermore, a gear is fixedly installed at the output end of the rotating motor, and tooth grooves are opened at the front and rear ends of the two moving rods.

[0011] Furthermore, both rotating plates are hinged to their upper surfaces and are threaded with hinges.

The rotating disk and the mounting plate are fixed together, and the mounting plate and the second protective plate are fixed together. The second protective plate, multiple first protective plates and the mounting plate can form a side plate. The side plate can be replaced according to the damaged part after damage.

[0016] 2. The hydraulic support for heavy equipment in coal mines proposed in this utility model includes a protective box. The protective box can protect the internal structure during use. When the rotating motor fixed to the bottom of the protective box is started, it can move the two moving rods inside the sliding cylinder to both sides, so that the main body can unfold the side support mechanism and fix the side support mechanism to the side wall of the mine. The upper end of the protective box is fixed with a second electric push rod through the mounting box. When the second electric push rod is started, it can adjust the position of the support platform. The support platform is equipped with a rotating plate.
