[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0019] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] The following is combined Figures 1-4 The method for installing manganese steel plates in the underground ore unloading station 1 of the present invention includes: Step S1: Fix I-beams to the arches of the roadways on both sides of the ore unloading station 1, and tighten and fix the first wire rope 21 along the longitudinal direction of the unloading trough to the I-beams on both sides.
[0021] In the above steps, the I-beams on both sides and the first wire rope 21 arranged longitudinally along the unloading trough together form a material sliding track, providing a longitudinal support foundation for the pulley block 3. This track can bear heavy manganese steel plates weighing several hundred kilograms to over a thousand kilograms, solving the problem of lacking reliable load-bearing tracks for heavy components in underground tunnels. Specifically, the I-beams can be fixed to the tunnel arch using anchor bolts.
[0022] Step S2: Assemble pulley block 3 using steel plates and bolts. Pulley block 3 is equipped with multiple sets of pulleys, both upper and lower.
[0023] In the above steps, the pulley block 3 is equipped with multiple sets of pulleys at the top and bottom, which can be adapted to the first wire rope 21 and the guide for the hoisting of the first wire rope 21, thereby reducing the frictional resistance of the first wire rope 21 during operation.
[0024] Step S3: Configure the first winch 4. The second wire rope 22 of the first winch 4 passes through the lower pulley of the pulley block 3 and the hook. One end of the second wire rope 22 is fixed to the I-beam, and the other end is reversed through the fixed pulley. The first winch 4 drives the hook to achieve lifting and lowering movement by winding and unwinding the second wire rope 22.
[0025] In the above steps, the first winch 4, together with the lower pulley of the pulley block 3 and the hook, forms a lifting drive link, which can realize the lifting and lowering of manganese steel plates, replacing manual lifting of heavy manganese steel plates.
[0026] Step S4: Configure a second winch 5 with a double trough. The two drums of the second winch 5 wind out two third steel wire ropes 23 with opposite directions. The two third steel wire ropes 23 are connected to both ends of the pulley block 3 through the fixed pulley in the chamber. One drum of the second winch 5 winds up the rope and the other drum unwinds the rope, driving the pulley block 3 to move back and forth longitudinally along the unloading trough.
[0027] In the above steps, the second winch 5 with the double-groove structure drives the pulley block 3 to move the load along the longitudinal direction of the unloading trough through the action of the drum, which can accurately transport the manganese steel plate to the installation point inside the unloading trough.
[0028] Step S5: Control the first winch 4 and the second winch 5 to rotate forward and backward to complete the construction of the first hoisting system, and repeat S1-S4 to build the second identical hoisting system (not shown in the figure).
[0029] In the above steps, two independent hoisting systems are set up to work together, which improves the efficiency of heavy manganese steel plate transfer and placement, and reduces the construction cycle of manganese steel plate lining support for underground mine unloading stations.
[0030] In a specific embodiment of the present invention, a safety operation control step is added in step S5. Before operation, the status of the first winch 4 and the second winch 5 is checked. When lifting, a test lift of 10-20cm is performed to verify stability. When lowering the heavy object, a low and uniform speed is maintained and the operator avoids being directly under the heavy object.
[0031] In the above embodiments, a status check of the winch equipment is conducted before each shift to identify potential problems such as broken wires in the wire rope and winch mechanism malfunctions, thus preventing accidents caused by falling objects due to equipment failure. A 10-20cm trial lift before hoisting verifies the load-bearing stability of the lifting points, slings, and the entire machine, and detects any issues with secure hoisting. Lowering heavy objects at a low and uniform speed avoids impact and swaying when lifting manganese steel plates.
[0032] Workers avoid being directly beneath heavy objects, mitigating the risk of injury from falling objects through the work process. The entire work process is adapted to the confined space working conditions of underground mine unloading stations, reducing the safety risks of manganese steel plate hoisting operations.
[0033] In a specific embodiment of the present invention, in step S2, the pulley block 3 is assembled from a 10mm thick steel plate and 18mm bolts, and two pulleys are provided on the upper and lower parts of the pulley block 3.
[0034] In the above embodiments, a 10mm thick steel plate is used to construct the base of the pulley block 3, ensuring the structural strength of the pulley block 3 and enabling it to handle lifting loads ranging from several hundred kilograms to over one thousand kilograms for manganese steel plates. 18mm bolts are used to assemble the components, ensuring a firm and reliable connection and preventing bolt loosening under vibration conditions in underground chambers. Two pulleys are arranged at the top and bottom respectively. The upper pulley is for the first wire rope 21 to travel on, while the lower pulley is for the lifting sling to pass through. This clear division of labor ensures even force distribution, reduces the likelihood of the first wire rope 21 getting stuck or experiencing uneven wear, and improves the smoothness of the pulley block 3's operation.
[0035] In a specific embodiment of the present invention, in step S1, a shock-absorbing pad is provided at the contact position between the first wire rope 21 and the I-beam.
[0036] In the above embodiments, adding a shock-absorbing pad at the contact point between the wire rope 21 and the I-beam can buffer the contact stress between the first wire rope 21 and the I-beam, avoid rigid hard friction between the first wire rope 21 and the I-beam, reduce wear on the first wire rope 21, and extend the service life of the first wire rope 21. Simultaneously, it can absorb the vibration and impact from hoisting operations, reduce vibration and noise generated during operation, protect the fixed structure of the I-beam, and prevent repeated impacts from causing the anchor points of the I-beam to loosen.
[0037] More specifically, the shock-absorbing pad can be made of rubber.
[0038] In a specific embodiment of the present invention, in step S5, a wireless remote control is used to control the forward and reverse rotation of the first winch 4 and the second winch 5.
[0039] In the above embodiments, two winches are remotely controlled to rotate in both directions via a wireless remote controller. Operators can operate from a safe area away from the hoisted load, without having to approach the dangerous edge of the ore pass. The wireless remote controller can also control the lifting and lowering of the hook and the forward and backward movement of the pulley block 3, facilitating the fine-tuning of the manganese steel plate to the installation position. This convenient operation is suitable for the complex working environment of underground chambers.
[0040] A second aspect of the present invention provides a manganese steel plate installation device for an underground ore unloading station 1, including a slide assembly, a pulley block 3, an upper and lower sling mechanism, a front and rear sling mechanism, and a controller.
[0041] The slide assembly includes I-beams fixed to the arches of the roadways on both sides of the ore unloading station 1, and a first wire rope 21 that is longitudinally tensioned and fixed to the I-beams on both sides of the unloading trough. The I-beams and the first wire rope 21 provide the basic walking track for the entire hoisting device, adapting to the large longitudinal span working conditions of the unloading station.
[0042] The pulley block 3 is mounted on the first wire rope 21, and the pulley block 3 has multiple sets of pulleys at the top and bottom. The pulley block 3 is hung on the first wire rope 21 to realize movement and guidance.
[0043] The lifting mechanism includes a first winch 4. A second wire rope 22 of the first winch 4 passes through the lower pulley of the pulley block 3 and the hook. One end of the second wire rope 22 is fixed to an I-beam, and the other end is redirected via a fixed pulley. The first winch 4 winds up and unwinds the wire rope 22, driving the hook to move up and down. The lifting mechanism relies on the first winch 4 to lift and lower the hook, completing the lifting and lowering of the manganese steel plate, thus solving the problem of vertical transport of heavy manganese steel plates.
[0044] The front and rear hoisting mechanism includes a second winch 5 with a double-groove structure. Two drums of the second winch 5 wind two third steel wire ropes 23 with opposite directions. The two third steel wire ropes 23 are connected to both ends of a pulley block 3 via fixed pulleys inside the chamber. The second winch 5 drives the pulley block 3 to move longitudinally back and forth along the unloading trough by winding rope with one drum and unwinding rope with the other. The front and rear hoisting mechanism relies on the double-groove second winch 5 to drive the pulley block 3 longitudinally, transporting the manganese steel plates to various installation points inside the unloading trough.
[0045] The controller is electrically connected to the first winch 4 and the second winch 5. The controller is used to control the forward and reverse rotation of the first winch 4 and the second winch 5, and integrates the control of lifting and longitudinal movement. The whole set of equipment can replace manual handling and hoisting, reduce labor intensity, and improve the installation efficiency of manganese steel plate lining support.
[0046] In a specific embodiment of the present invention, a shock-absorbing pad is further included, which is disposed at the contact position between the first wire rope 21 and the I-beam; the shock-absorbing pad is used to buffer the contact stress and reduce the wear of the first wire rope 21.
[0047] In the above embodiments, the shock-absorbing pad is arranged at the contact point between the first wire rope 21 and the I-beam, isolating the first wire rope 21 from direct metal-to-metal contact with the I-beam, buffering the impact contact stress brought about by the hoisting operation, preventing the first wire rope 21 from being cut and worn by the sharp edges of the I-beam, and extending the replacement cycle of the first wire rope 21. At the same time, it can buffer the vibration during the operation of the device, protect the anchoring structure of the I-beam arch, prevent the I-beam from loosening due to long-term vibration, and improve the operational reliability of the entire device.
[0048] In a specific embodiment of the present invention, both the first winch 4 and the second winch 5 are equipped with a low-speed uniform lowering gear.
[0049] In the above embodiments, the winch is equipped with a uniform speed lowering gear. During the lowering of the manganese steel plate, a stable low-speed lowering speed can be maintained, avoiding the free slippage of the suspended load and the resulting accelerated fall. This reduces the swaying and impact of the suspended components, makes it easier for the installers to adjust the alignment of the manganese steel plate, and improves the controllability and safety of the hoisting operation.
