Description

Technical Field

[0001] This invention relates to the field of ultra-high ore pass technology, specifically to an installation base for an ultra-high ore pass lined with manganese steel plates and its construction method. Background Technology

[0002] A pass is a tunnel that uses its own weight to slide ore downwards. It is widely used in mines developed in adits or shafts. There are two types of passes commonly referred to: one is the main pass, which serves one or more stages by transferring ore or waste rock from the upper stages to the lower stages or lower ore bins; it is an auxiliary development tunnel. The other is the stope pass, which serves one or more stops by transferring ore within the stope to the stages; it is a preparatory tunnel. Inclined passes are a component of high-speed passes. To ensure the service life of inclined passes, manganese steel plates are generally laid at the bottom.

[0003] In the existing technology, the manganese steel lining plate is directly laid at the bottom of the inclined chute. The manganese steel lining plate is subject to long-term impact and requires regular inspection and maintenance. When the manganese steel lining plate is inspected, operators need to enter the narrow inclined chute to carry out inspection and maintenance operations, which brings safety hazards and increases manpower expenditure. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an installation base for a manganese steel plate lining in an ultra-high chute and its construction method. This solves the problems in existing technologies, where the manganese steel plate lining is directly laid at the bottom of the inclined chute, the manganese steel plate lining is subject to long-term impact and requires regular inspection and maintenance, and the inspection and maintenance of the manganese steel plate lining requires operators to enter the narrow inclined chute for inspection and maintenance, which brings safety hazards and increases manpower expenditure.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: an installation base for a manganese steel plate lining an ultra-high chute, comprising a manganese steel plate, a base, an intermediate plate, and a top plate, wherein screws are provided at the bottom of the base, a groove is provided at the top of the base and a stress plate is provided in the groove, and guide rods are welded to both ends of the top of the stress plate.

[0008] The top of the intermediate plate has annular grooves on both sides, and a guide tube is inserted into the top of the groove. The guide tube is welded to the bottom of the top plate. The top of the guide rod passes through the intermediate plate and extends into the guide tube. A detection mechanism is set on the guide tube and located between the stress plate and the intermediate plate. The bottom of the manganese steel plate has a groove, and the top plate is set in the groove. The top of the manganese steel plate has a bolt groove, and a positioning bolt is set in the bolt groove. The bottom end of the positioning bolt passes through the manganese steel plate and the top plate in sequence and is threaded with a positioning nut. The positioning nut is welded to the bottom of the top plate. A speaker is set on the top of the intermediate plate.

[0009] The detection mechanism includes a threaded tube and a limiting ring. The limiting ring is fixed to the surface of a guide rod. The surface of the guide rod is provided with a limiting thread that mates with the threaded tube. A displacement block is sleeved on the surface of the threaded tube. A spring groove is provided on the top of the displacement block. An upper spring is inserted into the top of the spring groove and is sleeved on the surface of the guide rod. A lower spring is provided between the displacement block and the limiting ring and is arranged around the surface of the guide rod. A trigger button is provided at the bottom of the inner cavity of the displacement block. The trigger button is electrically connected to a speaker. When the force on the upper and lower springs is less than the safety value, the limiting thread continuously presses the trigger button. When the trigger button is pressed, the speaker does not work. When the trigger button is not pressed, the speaker works. Ball bearings are embedded in the surface of the threaded tube and are in contact with the inner wall of the displacement block.

[0010] A construction method for an installation base for a manganese steel plate lining of an ultra-high duct liner, comprising the aforementioned installation base for the manganese steel plate lining of an ultra-high duct liner, wherein the specific operation is as follows:

[0011] S1. Prepare manganese steel plates according to the condition of the inclined chute;

[0012] S2. Calculate the required number of installation bases for the manganese steel plate lining of the ultra-high chute based on the effective length of the manganese steel plate. Then prepare the corresponding number of installation bases for the manganese steel plate lining of the ultra-high chute. It is necessary to ensure that the distance between the installation bases of every two adjacent manganese steel plates lining the ultra-high chute is 1-1.5m.

[0013] S3. Bolt grooves and slots that fit together with the top plate are opened at the corresponding positions on the manganese steel plate;

[0014] S4. Fix the base relative to the inclined slide with screws, and then install the load-bearing plate, intermediate plate and top plate in sequence;

[0015] S5. After covering with the manganese steel plate, install the positioning bolts to complete the installation operation;

[0016] When in use, if the manganese steel plate deforms excessively or is subjected to force exceeding the safety value, the manganese steel plate presses against the upper and lower springs, causing the displacement block to move downward relative to the threaded tube. This prevents the limit thread from pressing the trigger button. When the trigger button is not pressed, the speaker operates. When the user notices the speaker operating, the following judgments should be made: if the speaker operates continuously, the manganese steel plate of the corresponding inclined conveyor should be inspected; if the speaker operates intermittently, the material feeding rate of the inclined conveyor should be slowed down.

[0017] (III) Beneficial Effects

[0018] This invention provides an installation base for a manganese steel plate lining in an ultra-high-strength chute and its construction method. It has the following beneficial effects:

[0019] The installation base and construction method of the manganese steel plate lining for the ultra-high chute, through simple improvements, enables an alarm to be triggered when the manganese steel plate lining is deformed to an excessive degree or subjected to stress exceeding the safety value. Operators can then take corresponding actions based on the alarm status, which increases the service life of the manganese steel plate lining, facilitates maintenance by operators, improves work efficiency, reduces the overall number of maintenance operations, and provides safety assurance for operators.

[0027] A construction method for an installation base for a manganese steel plate lining of an ultra-high duct liner, comprising the aforementioned installation base for the manganese steel plate lining of an ultra-high duct liner, wherein the specific operation is as follows:

[0028] S1. Prepare 1 manganese steel plate according to the condition of the inclined chute;

[0029] S2. Calculate the required number of installation bases for the manganese steel plate lining of the ultra-high chute based on the effective length of manganese steel plate 1. Then prepare the corresponding number of installation bases for the manganese steel plate lining of the ultra-high chute.

[0032] S5. After covering with manganese steel plate 1, install positioning bolt 10 to complete the installation operation;

[0033] When in use, if the deformation of the manganese steel plate 1 is too great or the force exceeds the safety value, the manganese steel plate 1 will press the upper spring 94 and the lower spring 98, thereby causing the displacement block 96 to move downward relative to the threaded tube 97, so that the limit thread 99 will no longer press the trigger button 92. When the trigger button 92 is not pressed, the speaker 12 will work. When the user finds that the speaker 12 is working, the following judgments will be made: if the speaker 12 works continuously, the manganese steel plate 1 of the corresponding inclined chute will be inspected and repaired; if the speaker 12 works intermittently, the material feeding rate of the inclined chute will be slowed down.

[0034] In summary, the installation base and construction method of the manganese steel plate lining for the ultra-high ore pass, through simple improvements, enables an alarm to be triggered when the manganese steel plate lining undergoes excessive deformation or is subjected to stress exceeding the safety value. Operators can then take corresponding actions based on the alarm status.
