Description

Technical Field

[0001] The present invention relates to the technical field of roadway support, and particularly to a rapid support-shifting structure for roadway support equipment. Background Art

[0002] Roadways are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrian passage, and various necessary preparatory works newly excavated for metallurgical equipment to extract ore. These passages are collectively referred to as roadways.

[0003] The long axis of the roadway is perpendicular to the horizontal plane, including vertical shafts, blind vertical shafts. The vertical shaft directly communicates with the ground. The one specifically or mainly used for ore hoisting is called the main shaft, and the one used for auxiliary hoisting such as waste rock, gangue hoisting, equipment lowering, and personnel lifting is called the auxiliary shaft. The blind vertical shaft does not directly communicate with the ground and is also called an adit. The adit specifically used for ore chuting is called a chute.

[0004] The long axis of the roadway is approximately parallel to the horizontal plane, such as adits, which directly communicate with the ground, including the main adit responsible for the main ore transportation task, the auxiliary adit responsible for auxiliary transportation, and the ventilation adit specifically used for ventilation, etc. Crosscuts do not directly communicate with the ground, and their long axes intersect obliquely or orthogonally with the ore body strike. Drifts are horizontal roadways that do not directly communicate with the ground, and their long axis directions are parallel to the ore body strike. The one arranged in the ore body is called an in-vein drift, and the one arranged in the rock is called an out-of-vein drift.

[0005] The long axis of the roadway forms a certain angle with the horizontal plane, such as inclined roadways that have the same functions as vertical shafts and adits and directly communicate with the ground, inclines, which are used for the up-drift or down-drift for mining ore bodies above or below a certain level, ramp roads, and raises, etc. The cross-sectional shape of the roadway is mostly arched, trapezoidal, or rectangular. When the surrounding rock is soft, it is circular, elliptical, or horseshoe-shaped. If the surrounding rock is unstable, support must be carried out. According to factors such as the stability of the surrounding rock, water inflow, cross-sectional shape and size, and service life, support forms such as shotcrete, bolts, reinforced concrete, or stone are selected.

[0006] Most of China's coal mines are underground mines, which require a large number of roadways to be excavated underground. Using roadway support to keep the roadways unobstructed and the surrounding rock stable is of great significance to coal mine construction and production. The basic purpose of roadway support is to relieve and reduce the movement of the surrounding rock, so that the roadway section will not be excessively reduced. At the same time, it is necessary to prevent the caving of the already separated and damaged surrounding rock. The effect of roadway support not only depends on the bearing capacity of the support itself, but is also affected by a series of factors such as the properties of the surrounding rock, the mechanical properties of the support, the installation density of the support, the timing of support installation, the installation quality of the support, and the contact method with the surrounding rock. Usually, in order to enable the roadway support to play an active role in regulating and controlling the deformation of the surrounding rock, the support should be installed before the surrounding rock loosens and fails, so that the support and the surrounding rock can jointly bear the load when the surrounding rock still has self-bearing capacity, rather than waiting until the surrounding rock has become loose, damaged, and almost completely lost its self-bearing capacity, and then using the support to bear the weight of the fallen rock mass. That is to say, the support and the surrounding rock should achieve common bearing under the conditions of mutual restraint and mutual dependence.

[0007] However, when using roadway support equipment for support, it is not convenient to move the equipment. Moreover, both sides of the support equipment use hydraulic rods for lifting and support. Therefore, it takes a long time for contraction and extension, and it cannot be directly moved. Therefore, it is very inconvenient to use. Summary of the Invention

[0031] Please refer to Figures 1-4 , a rapid support-shifting structure for a roadway support device, including a support plate 1 fixedly connected with a universal wheel 2 at the bottom, a slider 12 fixedly connected with a pressing plate 13 at the top, and a threaded rod 14. A support frame 3 for auxiliary support is fixedly connected to the top of the support plate 1. A rotatable adjusting rod 4 is inserted into the top of the support frame 3. Through the arrangement of the adjusting rod 4, when the motor 5 rotates, the threaded sleeve 6 can be directly driven to move up or down, so as to raise or lower the whole device;

[0032] Among them, a motor 5 for providing power is fixedly installed at the bottom of the support frame 3. The output end of the motor 5 is key-connected to the bottom of the adjusting rod 4.

Through the setting of the threaded sleeve 6, when the adjusting rod 4 rotates, the support rod 7 can be directly driven to move up or down, so as to adjust the height of the support plate 8. Therefore, it is not necessary to wait until all the hydraulic rods of the support equipment are lifted, and the device can be directly lifted off the ground, and then the support equipment can be driven to move;

[0033] Among them, baffles 9 for limiting are threadedly connected to both sides of the outer surface of the support plate 8. Fixing bolts 10 for fixing are threadedly inserted through both sides of the outer surface of the baffle 9.

The other end of the inner side wall of the positioning sleeve 16 is inserted into one end of another limiting plate 15. By rotating the threaded rod 14, the slider 12 can be driven to move. Therefore, the pressing plate 13 can be driven to clamp and fix the upper support equipment. Through the setting of the limiting plate 15, the two support rods 7 on both sides can be directly tightened and fixed from the middle, so as to control the opening angle of the two support rods 7, so as to facilitate the device to adjust itself according to the width of the roadway. Through the setting of the positioning sleeve 16, the sliding of the limiting plate 15 can be guided, so as to ensure the stability of the limiting plate 15 during sliding;

[0036] Among them, the outer surface of the sleeve 16 is threaded with a pressing rod 17 for pressing. One end of the pressing rod 17 passing through the sleeve 16 abuts against the outer wall of the limiting plate 15.
