Description

Technical Field

[0001] The utility model relates to the field of support for coal mining, in particular to support equipment for coal mining with a stable structure. Background Art

[0002] The scope of a coal mine includes a large area above ground, underground and related facilities. A coal mine is a reasonable space excavated by humans when digging geological strata rich in coal. It usually includes tunnels, shafts and mining faces, etc. Coal is the main solid fuel. When a coal mine is mined, in order to prevent coal slag from falling, support equipment is generally used to support and block it.

[0003] At present, when the support equipment is in use, most of the existing ones directly install a protective plate on the top through a hydraulic rod. In this way, when encountering large coal slag falling during use, the support equipment is prone to shaking and tilting, which is prone to instability and reduces the safety of mining. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a support device for coal mining with a stable structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model proposes a supporting device for coal mining with a stable structure, including a supporting frame, two fixing ears are fixedly installed on both sides of the supporting frame, and a second hydraulic rod is fixedly installed at the bottom of the four fixing ears;

[0006] A stabilizing mechanism is provided inside the support frame, and the stabilizing mechanism includes a truss, a mounting plate, a third hydraulic rod and a base plate. Three trusses are fixedly installed on both sides of the inner wall of the support frame, two mounting plates are fixedly installed on the bottom of one of the trusses, two third hydraulic rods are fixedly installed on the bottom of the two mounting plates, and the bottom ends of the four third hydraulic rods are fixedly installed with a base plate.

[0007] In one example, two connecting plates are fixedly installed at the bottom of the support frame, and fixing rods are fixedly installed on the sides of the two connecting plates close to each other.

[0008] In one example, ends of the two fixing rods close to each other are both rotatably connected to a beam-exploring plug plate.

[0009] In one example, fixed shafts are fixedly installed on both sides of the beam-detecting plug plate, and ends of the two fixed shafts that are away from each other are threadedly connected to limited circular plates.

[0010] In one example, hinged joints are fixedly installed on the right sides of both sides of the support frame, and the inner walls of the two hinged joints are rotatably connected with fixed heads.

[0011] In one example, a first hydraulic rod is fixedly mounted on one side of the two fixed heads, and the output shafts of the two first hydraulic rods are interlaced with the fixed shaft.

[0012] The support equipment for coal mining with a stable structure proposed by the utility model can bring the following beneficial effects:

[0013] 1. A support device for coal mine development with a stable structure is provided. The third hydraulic rod is fixed on a base plate and then a mounting plate is fixed on the top of the third hydraulic rod. A truss is fixed on the top of the mounting plate to stabilize both sides of the support frame to prevent the support frame from tilting due to impact force. The support frame is stabilized as a whole by a stabilizing mechanism to achieve a better stabilizing support effect and increase safety.

[0014] 2. The support equipment used in coal mine development with a stable structure retracts the first hydraulic rod and drives the beam-splitting plate to rotate around the fixed rod through the fixed shaft, and opens the beam-splitting plate to detect the coal mine in front of the support frame to observe whether coal blocks have fallen.
