[0002] A mine is a general term for shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. According to the shape of the mine, it can be divided into inclined shafts, vertical shafts, adits and the like. In order to facilitate the entry and exit of construction personnel in the mine construction process, a lifting device needs to be installed inside the mine. At present, the lifting device applied to the mine, especially the vertical shaft, is only a simple vertical lifting mechanism installed at the opening position of the mine.

In order to ensure the safety of the vertical lifting device, the most commonly used is to install a tension locking mechanism at the connection end of the car and the cable. However, in special circumstances, the locking mechanism at the connection end alone cannot completely avoid the car from falling. It is unable to monitor the running speed of the car in real time, the safety coefficient is limited, and it cannot play a buffering function.

[0027] The present application will be further described below in conjunction with the drawings and examples.

[0028] In the description of the present application, it should be noted that unless otherwise expressly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] Figure 1 、 Figure 2 and Figure 3 The electric control system of a mine construction lifting device is shown in the figure, which comprises a longitudinal support frame 1 installed inside the mine, a top-mounted driving assembly installed at the upper opening position of the mine, a lifting device body installed inside the longitudinal support frame 1, and an electric control type elastic speed reduction mechanism installed at the upper and lower ends inside the longitudinal support frame 1.

[0030] The top-mounted driving assembly is a prior art, which is used to drive the lifting device body to lift inside the longitudinal support frame 1, and the principle is the same as the power unit of the vertical elevator on the market.

[0031] In order to improve the internal guiding property, longitudinal guide rails 2 are welded and fixed on the inner side of the longitudinal support frame 1, and lateral speed reduction guide rails 3 are movably assembled on both sides of the longitudinal guide rails 2.

[0032] In order to cooperate with lifting, the lifting device body comprises a main cabin 4 located inside the longitudinal support frame 1, a top pull rope 5 installed at the upper end of the main cabin 4 for connecting the top-mounted driving assembly, a counterweight 6 installed at the other end of the top pull rope 5, and an elastic stabilizing support installed on the outer side of the main cabin 4.

[0033] In order to cooperate with electric control overturning, the electric control type elastic speed reduction mechanism comprises an electric control sensor module 7 fixedly installed on the inner side of the longitudinal guide rail 2, an external overturning support arm 8 movably assembled inside the lateral speed reduction guide rail 3 through an internal adjusting block, a middle connecting shaft 9 installed between the external overturning support arms 8 on both sides of the longitudinal guide rail 2, an overturning limiting frame 10 fixed on the middle connecting shaft 9, an internal sliding block 11 movably assembled inside the lateral speed reduction guide rail 3, and an elastic telescopic connecting arm 12 movably linked between the external overturning support arm 8 and the internal sliding block.

[0034] The internal adjusting block has an overturning limiting block on the outer side, and the overturning angle of the external overturning support arm 8 is 0°-130°.

[0035] The electric control sensor module 7 is a prior art, which is used to detect the position of the elastic stabilizing support on the outer side of the main cabin 4, so as to monitor the position of the main cabin 4, and to control the outward overturning of the external overturning support arm 8,

[0036] In order to match the lifting adjustment, the lateral speed control guide rail 3 side wall is provided with a strip-shaped lifting opening 13 which is connected with the inside of the longitudinal guide rail 2, and the inside of the lateral speed control guide rail 3 is provided with a speed reduction spring 14.

[0037] In order to match the inside limiting, the inside of the lateral speed control guide rail 3 is provided with an inwardly protruding inside limiting frame 15.

[0038] In order to match the outward extrusion and turning of the external turning support arm 8, the inside of the lateral speed control guide rail 3 is provided with an inside bending elastic sheet 16 which is used to control the outward turning of the external turning support arm 8, the inside of the external turning support arm 8 is provided with an inside assembly frame which matches the inside bending elastic sheet 16, and the outside end of the inside bending elastic sheet 16 is connected with the external turning support arm 8 by inserting the inside assembly frame.

[0039] In order to match the limiting of the inside bending elastic sheet 16 in the daily state, and to avoid the influence of the external turning support arm 8 on the normal operation of the main car 4, the inside of the lateral speed control guide rail 3 is provided with an electronic limiter 17 which is used to limit the inside bending elastic sheet 16.

[0040] The electronic limiter 17 is a prior art which is used to extrude and limit the inside bending elastic sheet 16, and is disconnected in use so as to make the inside bending elastic sheet 16 extrude outwardly.

[0041] In order to match the stability of the outside when the main car 4 is in normal operation, the elastic stability support includes a lateral assembly seat 18 which is fixed on the outside of the main car 4, an external assembly cover 19 which is movably sleeved on the outside of the lateral assembly seat 18, an extrusion spring 20 which is installed on the inside top surface, inside bottom surface and inside surface of the external assembly cover 19, and a guide wheel set 21 which is movably assembled on the top corner and bottom corner of the external assembly cover 19.

[0042] The outer assembly cover 19 is inserted into the longitudinal guide rail 2, and then rolled by the guide wheel set 21, so that the main cabin 4 can stably ascend and descend. At the same time, the existing technology induction magnetic block inside the lateral assembly seat 18 is used to cooperate with the electric control sensor module 7 to monitor the position of the main cabin 4. When the induction magnetic block passes through the electric control sensor module 7, the electric control sensor module 7 senses a signal. According to the sequence and interval of the induction of the electric control sensor module 7 between adjacent positions, the running direction and speed of the main cabin 4 can be quickly judged. When the speed exceeds the maximum speed, the electronic limit stopper 17 of the corresponding running direction is controlled to be closed. After the inner side bending elastic sheet 16 loses the limitation, the outer turning support arm 8 is extruded outward, the outer turning support arm 8 and the turning limiting frame 10 are turned outward, and an elastic buffer device is formed in the running direction of the main cabin 4. Therefore, when the main cabin 4 collides with the outer turning support arm 8, the outer turning support arm 8 is first controlled to extrude the deceleration spring 14, the elastic stable support is inserted into the turning limiting frame 10, and then the elastic telescopic connecting arm 12 is stretched to perform multiple deceleration.

[0043] In order to cooperate with the connection of the main cabin 4 and the top of the outer turning support arm 8, a top telescopic blind hole is formed at the top end of the outer turning support arm 8. An inner telescopic head 22 is inserted into the top telescopic blind hole, and a top limiting hook 23 is axially fixed to the top end outside the inner telescopic head 22.

[0044] In order to cooperate with the internal telescoping and limiting, an outward protruding lateral limiting block 24 is fixedly installed on the outer side wall of the inner telescopic head 22. A lateral limiting opening 25 is formed on the outer side surface of the outer turning support arm 8, and cooperates with the lateral limiting block 24. An outer extrusion spring 26 is sleeved outside the inner telescopic head 22 in the top telescopic blind hole.

[0045] The outer extrusion spring 26 extrudes the lateral limiting block 24 inward, so as to control the inner telescopic head 22 to shrink inward. Therefore, when the top limiting hook 23 is connected with the main cabin 4, the elastic extrusion shock-absorbing effect can be finally achieved by the action force of the outer extrusion spring 26.

[0046] In order to cooperate with the guidance and connection limiting of the main cabin 4, a guide groove 27 is formed on the upper surface and the lower surface of the main cabin 4, and cooperates with the outer turning support arm 8. An inner safety rod 28 is installed on the inner side surface of the guide groove 27, and cooperates with the top limiting hook 23.

[0047] When the main cabin 4 rapidly rises or descends, the guide groove 27 will first collide with the outer turning support arm 8. When the supporting force of the outer turning support arm 8 is insufficient to support the main cabin 4, the top limiting hook 23 at the top end of the outer turning support arm 8 will be hung on the inner safety rod 28, so as to change from elastic sliding connection to rigid connection, thereby achieving the limiting function again.

[0048] With the above ideal embodiments according to the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the scope of the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
