The drawings in the embodiments of the invention: the different types of hatching in the figures are not given the national standards, do not require the material of the elements, and distinguish between cross-sectional views of the elements in the figures.

Referring to fig. 1-4, a protection device for a coal lifting hole of a power plant comprises a building top plate 1, a lifting hole 10 is formed in the building top plate 1, a mounting seat 3 is fixedly mounted on the side surface of an inner cavity of the lifting hole 10, a pulley 2 is movably mounted at the bottom of the inner cavity of the mounting seat 3, a supporting plate 5 is movably mounted at the top of the pulley 2, a clamping seat 4 is fixedly mounted on the front surface of the supporting plate 5, a first tension spring 6 is fixedly connected to the inner side surface of the clamping seat 4, the other end of the first tension spring 6 is fixedly connected with the side surface of the inner cavity of the mounting seat 3, a spur rack 7 is fixedly mounted at the top of the supporting plate 5, and a rotating shaft 9 is movably mounted at.

The outer surface of the rotating shaft 9 is movably connected with an outer protection plate 12, the top of the outer protection plate 12 extends to the upper part of the mounting seat 3, the side surface, located above the mounting seat 3, of the top of the outer protection plate 12 is fixedly provided with an anti-tilting block 13, the anti-tilting block 13 can be arranged to prevent the outer protection plate 12 from tilting outwards under the action of a second tension spring 11, and ensure that the outer protection plate 12 is in a vertical state, the side surface, located on the outer protection plate 12, of the outer surface of the rotating shaft 9 is fixedly sleeved with an outer ferrule 20, the side surface, located on the outer ferrule 20, of the outer surface of the rotating shaft 9 is movably sleeved with a ratchet wheel 19 matched with the ratchet wheel 21, the side surface, located on the outer surface of the ratchet wheel 19, of the outer gear ring 8 matched with the spur rack 7 is fixedly installed on the side surface of the ratchet wheel, thereby when needs carry out the return to bearing plate 5, guarantee the meshing between external gear circle 8 and the spur rack 7, before bearing plate 5 does not have the unblock, be contactless between external gear circle 8 and the spur rack 7, can prevent meshing between the two like this, can't move when leading to bearing plate 5 unblock, through setting up adjusting screw 18, ratchet 19, pawl 21, external gear circle 8, the cooperation of spur rack 7, make people break away from the back in lifting hole 10 department, make people reciprocate to drive outside guard plate 12 and make bearing plate 5 get back to the normal position and then lock, and then make the device can reuse.

The outer surface of the rotating shaft 9 is fixedly connected with a hinged plate 14, the side surface of the hinged plate 14 is positioned at the near end of the lifting hole 10 and is fixedly connected with a second tension spring 11, the other end of the second tension spring 11 is fixedly connected with the side surface of the inner cavity of the mounting seat 3, the arrangement of the second tension spring 11 can prevent people from just contacting with an external protection plate 12 to cause the external protection plate 12 to act, so that the action of the support plate 5 is triggered by mistake, and further the trouble of returning the support plate 5 in the later period is prevented, the side surface of the hinged plate 14 is movably hinged with a hinged rod 15, the front surface of the inner cavity of the mounting seat 3 is positioned above the clamping seat 4 and is movably hinged with a Z-shaped clamping plate 16 matched with the clamping seat 4, the other end of the hinged rod 15 is movably hinged with the top of the Z-shaped clamping plate 16, and after people accidentally fall on the external protection plate 12 through, can carry out the unblock to bearing plate 5 fast to make the pulling force effect of first extension spring 6 make bearing plate 5 enter into lifting eye 10 fast, support people's health, thereby prevent that people from dropping from lifting eye 10.

The quantity of outside guard plate 12 is four, and four outside guard plates 12 are trapezoidal plate, are connected through elasticity protecting band 17 between four outside guard plates 12, and outside guard plate 12 openly is trapezoidal, and elasticity protecting band 17 not only can compensate the vacancy between the outside guard plate 12, can drive other outside guard plates 12 through the action of an outside guard plate 12 moreover and move to make two bearing plates 5 carry out the unblock action.

The length value of the supporting plate 5 is one half of the width of the lifting hole 10, and the side surfaces of the two symmetrical supporting plates 5 are provided with clamping grooves and bulges which are matched with each other. The clamping groove is matched with the protrusions, so that the unlocking rear side faces of the two bearing plates 5 are clamped, the two bearing plates 5 are mutually depended on each other, and the supporting strength of the bearing plates 5 is guaranteed.

The working principle is that when people work in a weight chamber, if a body falls to the position of the external protection plate 12 by accident, the external protection plate 12 inclines, then the rotating shaft 9 overcomes the pulling force of the second tension spring 11 to rotate clockwise, then the hinged plate 14 drives the hinged rod 15 to move towards the far end of the lifting hole 10, further the hinged rod 15 drives the Z-shaped clamping plate 16 to rotate anticlockwise, further the Z-shaped clamping plate 16 is separated from the clamping seat 4, at the moment, the pulling force of the first tension spring 6 acts on the support plate 5, so that the support plate 5 rapidly enters the lifting hole 10 to block the lifting hole 10, further people are supported, when one external protection plate 12 inclines, the corresponding support plate 5 can enter the lifting hole 10 by driving other external protection plates 12 to incline under the pulling action of the elastic protection belt 17, when people climb out of the lifting hole 10, at the moment, the adjusting screw 18 is rotated, the ratchet wheel 19, the external gear ring 8 and the rotating shaft 9 are in the same center, and further the external gear ring 8 is meshed with the spur rack 7, at the moment, people manually swing the external protection plate 12 around the rotating shaft 9, the external protection plate 12 drives the rotating shaft 9 to rotate in the swinging process, so that the external ferrule 20 drives the pawl 21 to rotate, the pawl 21 is clamped on the ratchet wheel 19, and further the external gear ring 8 rotates, when the external ferrule 20 rotates anticlockwise, the ratchet wheel 19 cannot rotate, when the external ferrule 20 rotates clockwise, the ratchet wheel 19 rotates clockwise under the driving of the pawl 21, so that the external gear ring 8 rotates clockwise, and through the meshing effect with the spur rack 7, the spur rack 7 drives the support plate 5 to be far away from the lifting hole 10 in a clearance manner, finally, the Z-shaped clamping plate 16 will be clamped on the clamping seat 4, locking the support plate 5, and the external protection plate 12 will be in a vertical state under the action of the second tension spring 11.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
