Description

Technical Field

[0001] The present invention relates to the field of geological mining sampling equipment, and more particularly to a stratified sampling device for geological mining. Background Art

[0002] Layered sampling in geological mining is an important geological exploration method. Its purpose is to accurately understand and evaluate the geological characteristics and ore quality of the ore body. Layered sampling can provide mining companies with detailed ore grade and geological structure information, which helps to optimize mine design, improve mineral resource utilization, reduce production costs, and provide a scientific basis for the rational development of mineral resources and environmental governance. However, when conducting geological mining exploration, soil samples at different depths are usually collected and tested.

[0003] However, during collection, a drill is usually used to drill a hole, and then a sampling device is inserted into the drilled hole to collect samples. In order to obtain soil samples at different depths, it is usually necessary to gradually deepen the drilling depth after sampling and perform sampling and collection in batches. It is necessary to frequently switch the drill bit and the collection device for drilling and collection operations, which is cumbersome, time-consuming and labor-intensive, and increases the workload of the staff. Therefore, we propose a layered sampling device for geological mining to solve the above problems. Summary of the Invention

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] Example:

[0043] See also Figure 1-2A stratified sampling device for geological mining includes: a drilling mechanism 1, which is used for stratified sampling in geological mining; a driving mechanism 2, which is arranged above the drilling mechanism 1, and the output end of the driving mechanism 2 is connected to the top of the drilling mechanism 1, and the driving mechanism 2 is used to drive the drilling mechanism 1 to rotate; a supporting mechanism 3, which is arranged outside the drilling mechanism 1, and is used to provide support for the driving mechanism 2 and adjust the position height of the driving mechanism 2; a control mechanism 4, which is arranged on one side of the supporting mechanism 3, and is used to control the operation of the driving mechanism 2 and the supporting mechanism 3;

[0044] Through the support mechanism 3, it can be stably and firmly erected in the designated position, and can also provide an installation foundation for the driving mechanism 2 and the control mechanism 4. Then, through the driving mechanism 2, the drilling mechanism 1 can be installed and the drilling mechanism 1 can be driven to rotate at high speed. Under the telescopic lifting and lowering of the support mechanism 3, the driving mechanism 2 and the drilling mechanism 1 can be synchronously driven to move up and down, so that the drilling mechanism 1 can drill into the geology and store the drilled samples inside it. By continuously expanding and extending the drilling mechanism 1, the drilling mechanism 1 can sample a large number of samples at one time, thereby ensuring the stratification stability of each geological mineral material during sampling. This can greatly reduce the tedious operation of the staff to replace the drill bit and the collection device back and forth, and reduce the labor intensity of the staff. At the same time, through the upward movement of the support mechanism 3, the drilling mechanism 1 can be synchronously driven to move upward, so that the user can conveniently lift the drilling mechanism 1 up, thereby improving the sampling efficiency of the user.

[0045] See Figure 2-Figure 6The drilling mechanism 1 includes a connecting member 11, the top of the connecting member 11 is connected to the output end of the driving mechanism 2, the bottom end of the connecting member 11 is plugged with an extension member 12, and the bottom end of the extension member 12 is connected to a sampling member 13. The connecting member 11 includes a first flange plate 111 arranged at the output end of the driving mechanism 2, and a transmission shaft 112 is fixedly provided at the center position of the bottom surface of the first flange plate 111. A positioning card slot 113 for plugging the extension member 12 is provided at the bottom end of the transmission shaft 112, and a guide hole 114 is provided at the center position of the top surface of the inner cavity of the positioning card slot 113. An oil filling pipe 115 is embedded in one side wall of the transmission shaft 112, and one end of the oil filling pipe 115 is conductively connected to the guide hole 114. The extension member 12 includes an extension tube 121, and the top end of the extension tube 121 is integrally formed with a hole for plugging into the inner cavity of the positioning card slot 113 The first clamping tube 122 has a plurality of first limiting holes 123 formed on the outer wall of the first clamping tube 122, and a plug-in slot 124 is formed on the bottom end of the inner cavity of the extension tube 121. The outer wall of the extension tube 121 is provided with a plurality of stepped screw holes 125 on the outer side of the plug-in slot 124. A limiting screw 126 is rotatably installed in the inner cavity of each stepped screw hole 125. A first sealing ring 127 is sleeved on the outer side of the first clamping tube 122, and an annular groove 128 is provided on the outer wall of the extension tube 121 at the upper middle position. The sampling component 13 includes a sampling tube 131, a toothed ring 132 is fixedly provided on the bottom end of the sampling tube 131, and a second clamping tube 133 is integrally formed on the top end of the sampling tube 131. The outer wall of the second clamping tube 133 is provided with a plurality of second limiting holes 134, and a second sealing ring 135 is sleeved on the outer side of the second clamping tube 133;

[0046] The driving shaft 112 in the drilling mechanism 1 can be connected to the output end of the driving mechanism 2 through the first flange plate 111, and can provide space for the positioning slot 113 and the guide hole 114. At the same time, the oil filling pipe 115 can be installed so that it can be connected to the guide hole 114. Through the positioning slot 113, it can be engaged with the first clamping tube 122 on the extension tube 121. Through the engagement of the two, the driving mechanism 2 can simultaneously drive the first clamping tube 122 to rotate while driving the first flange plate 111 to rotate. Through the plug-in slot 124 at the bottom end of the first clamping tube 122, it can be engaged with the second clamping tube 133 on the sampling tube 131, and by rotating the ladder The limiting screw 126 in the screw hole 125 can make one end of the limiting screw 126 be inserted into the second limiting hole 134 on the second clamping tube 133, so that the sampling tube 131 and the extension tube 121 can be connected together, and then the sampling tube 131 can be driven to rotate synchronously while the extension tube 121 rotates. Since the bottom end of the sampling tube 131 is provided with a toothed ring 132, when the sampling tube 131 rotates, the geology can be drilled under the rotation of the toothed ring 132, so that the sampling tube 131 can be probed downward, and the first clamping tube 122 on the extension tube 121 can also be engaged with the plug-in slot 124 on the other extension tube 121, and by rotating the upper step of the other extension tube 121 The limiting screw 126 in the ladder screw hole 125 can make one end of the limiting screw 126 engage in the first limiting hole 123, so that multiple extension tubes 121 can be stacked and extended in sequence, thereby increasing the depth of the sampling tube 131, and the sample will continuously enter the sampling tube 131 and the extension tube 121, which is convenient for the sample to accumulate inside, so that samples of various geological layers can be obtained at one time, which greatly improves the integrity of the sample and the sampling efficiency. When a certain number of extension tubes 121 are extended, an appropriate amount of lubricant is injected into the oil filling tube 115, so that the lubricant can be injected into the extension tube 121 at the top through the guide hole 114, thereby making the lubricant The lubricant flows downward along the top extension tube 121, so that the lubricant can penetrate most of the extension tube 121, so as to reduce the friction between the sample and the inner wall of the extension tube 121, and facilitate the upward accumulation of the sample in each extension tube 121. The first sealing ring 127 and the second sealing ring 135 can ensure the connection sealing effect when the extension tube 121 and the drive shaft 112 and the sampling tube 131 and the extension tube 121 or multiple extension tubes 121 are connected. The annular groove 128 on the outer wall of the extension tube 121 can be used to support this place when the support mechanism 3 is raised, thereby driving the extension tube 121 to move upward, and then the extension tube 121 can be pulled out, so that the user can take out the downward extension tube 121.

[0047] See Figure 2 、 Figure 4 and Figure 7The drive mechanism 2 includes a motor 21, an output end of the motor 21 is connected to an eccentric gearbox 22, and an output end of the eccentric gearbox 22 is connected to a drive shaft 23, and a second flange plate 24 is fixedly provided at the bottom end of the drive shaft 23, and the second flange plate 24 is detachably connected to the first flange plate 111 by a first connecting bolt 25;

[0048] Through the motor 21 and the eccentric gearbox 22 in the drive mechanism 2, it can be installed at the specified position of the support mechanism 3, and the motor 21 can drive the eccentric gearbox 22 to operate, so that the drive shaft 23 can rotate at high speed, and then can synchronously drive the second flange plate 24 to rotate. Since the second flange plate 24 is detachably connected to the first flange plate 111 through the first connecting bolt 25, when the second flange plate 24 rotates, it can synchronously drive the first flange plate 111 to rotate, so that the drive shaft 23 can drive the drive shaft 112 to rotate, and then can provide a rotational driving force for the sampling tube 131.

[0049] See Figure 2 、 Figure 7 and Figure 8 The supporting mechanism 3 includes a triangular support plate 31, a through hole 32 is provided in the middle position of the top surface of the triangular support plate 31, an outer tube 33 is fixedly provided on the bottom surface of the triangular support plate 31 and located at the triangular position, the inner cavity of each outer tube 33 is plugged with an inner tube 34, the bottom surface of the inner cavity of the inner tube 34 is provided with an electric hydraulic telescopic rod, and the top of the telescopic end of the electric hydraulic telescopic rod is connected to the top of the inner cavity of the outer tube 33, and the bottom end of each inner tube 34 is fixedly provided with a base 35, and at least one anchor rod 36 is plugged into one side of the top surface of the base 35, a stabilizing frame 37 is provided under the triangular support plate 31, and the outer side of the stabilizing frame 37 is respectively connected to the three outer tubes 33, the inner side wall of each outer tube 33 is provided with a knockout piece 38, and the top surface of the triangular support plate 31 is provided with a protective cover 39;

[0050] The triangular support plate 31 in the supporting mechanism 3 can provide a stable foundation for the motor 21 and the eccentric gearbox 22, and can also provide space for the through hole 32, and can also install and fix the three outer tubes 33. Since the inner cavity of each outer tube 33 is plugged with an inner tube 34, and the bottom surface of the inner cavity of the inner tube 34 is provided with an electric hydraulic telescopic rod, and the top of the telescopic end of the electric hydraulic telescopic rod is connected to the top of the inner cavity of the outer tube 33, the outer tube 33 can be synchronously driven to move on the inner tube 34 through the extension and contraction of the electric hydraulic telescopic rod, thereby adjusting the height of the use position of the triangular support plate 31. The three bases 35 can be fixed to the bottom ends of the three inner tubes 34 respectively, and the anchor rods 36 can be used to fix the base 35 to the ground, thereby improving the stability of the base 35 in use, so as to enhance the support of the inner tube 34. In order to ensure the stability of the support, the stabilizing frame 37 can be installed on the three outer tubes 33 and can be rolled to fit the outer wall of the extension tube 121, which can further improve the supporting stability of the three outer tubes 33 and provide limited support for the extension tube 121, thereby improving the rotation stability of the extension tube 121. The three ejector members 38 can be fixed on the three outer tubes 33 respectively and can be adjusted when the extension tube 121 needs to be pulled out, so that the telescopic end of the ejector member 38 can be against the annular groove 128. Through the extension of the electric hydraulic telescopic rod, the outer tube 33 can be driven upward, and the ejector member 38 can be driven upward synchronously. At this time, the ejector member 38 against the annular groove 128 will synchronously drive the extension tube 121 to move upward, thereby making it convenient for the user to smoothly remove the extension tube 121.

[0051] See Figures 8-10 37, and the stabilizing frame 37 comprises three stabilizing sleeves 371, and the three stabilizing sleeves 371 are respectively arranged on the three outer tubes 33, and two adjacent stabilizing sleeves 371 are connected by a connecting rod 372, and at least one side wall of each stabilizing sleeve 371 is provided with an internal threaded hole 373, and the inner cavity of each internal threaded hole 373 is rotatably installed with a fixing screw 374, and the middle part of each connecting rod 372 is provided with a first electric push rod 375, and the telescopic end of the first electric push rod 375 is installed with a bracket 376, and a first ball groove 377 is provided in the middle position of the top surface of the bracket 376, and a clamping seat 378 is provided on the upper surface of the bracket 376, and both sides of the clamping seat 378 are connected to the two sides of the bracket 376 by second connecting bolts 3711, and a second ball groove 379 is provided in the middle position of the bottom surface of the clamping seat 378, and a ball 3710 is provided between the second ball groove 379 and the first ball groove 377.

[0052] The three stabilizing sleeves 371 in the stabilizing frame 37 can be installed on the three outer tubes 33 respectively, and the three stabilizing sleeves 371 can be connected into a whole through the three connecting rods 372. By rotating the fixing screws 374 on the internal threaded holes 373, the stabilizing sleeves 371 can be fixed on the outer tube 33, and the position height of the stabilizing sleeves 371 on the outer tube 33 can be flexibly adjusted, thereby improving the convenience of equipment use and the stability of the support of the three outer tubes 33. The first electric push rod 375 can be installed on the connecting rod 372 and can drive the position of the bracket 376 installed at its telescopic end. Since the middle position of the top surface of the bracket 376 is provided with a first electric push rod 375, the first electric push rod 375 can be installed on the connecting rod 372 and can drive the position of the bracket 376 installed at its telescopic end. A ball groove 377 is provided, and a second ball groove 379 is also provided in the middle position of the bottom surface of the holder 378 above the bracket 376. At the same time, the bracket 376 and the holder 378 are connected together by a second connecting bolt 3711. Therefore, the combination of the first ball groove 377 and the second ball groove 379 can not only install the ball 3710, but also enable the ball 3710 to roll in its inner cavity. At this time, the first electric push rod 375 is extended, so that the ball 3710 can be attached to the outer wall of the extension tube 121, thereby supporting and limiting the rotating extension tube 121, thereby improving the rotation stability of the extension tube 121.

[0053] See Figure 8 、 Figure 11 The ejector 38 includes a positioning plate 381, a double-ear fixing seat 382 is provided on the outer wall of the positioning plate 381 near the bottom end, a second electric push rod 383 is rotatably connected to the double-ear fixing seat 382, ​​and a top tongue 384 is connected to the telescopic end of the second electric push rod 383. A mounting bracket 385 is provided on the outer wall of the positioning plate 381 near the top end. A forward and reverse motor 386 is provided in the inner cavity of the mounting bracket 385. The output end of the forward and reverse motor 386 is connected to a winding rack 387. A pull rope 388 is wound around the winding rack 387. One end of the pull rope 388 is connected to a pull sleeve 389. The pull sleeve 389 is sleeved on the middle part of the second electric push rod 383.

[0054] The positioning plate 381 in the ejector 38 can be fixed to the outer wall of the outer tube 33, and the second electric push rod 383 can be movably installed through the double-ear fixing seat 382. At the same time, the forward and reverse motor 386 can be installed through the mounting bracket 385. Since the reeling rack 387 on the output end of the forward and reverse motor 386 can be connected to the pull sleeve 389 on the second electric push rod 383 through the pull rope 388, and the telescopic end of the second electric push rod 383 is connected with the top tongue 384, when it is necessary to pull out the extension tube 121, the reeling rack 387 can unwind the pull rope 388 through the unwinding of the forward and reverse motor 386, so that the second electric push rod 383 can rotate around the axis of the double-ear fixing seat 382 until it reaches the appropriate position. At this time, the forward and reverse motor 386 stops unwinding. By extending and retracting the second electric push rod 383, the tongue 384 can be pressed against the annular groove 128, so that the two can be engaged with each other. Then, by extending the electric hydraulic telescopic rod, the outer tube 33 can be driven to move upward, and the outer tube 33 can synchronously drive the ejection member 38 to move upward as a whole, so that the tongue 384 on the ejection member 38 can be pulled upward against the extension tube 121, reducing the upward traction force of the eccentric gearbox 22 on the drive shaft 112 when the extension tube 121 is pulled upward, thereby improving the safety of the eccentric gearbox 22. Conversely, by rewinding the forward and reverse motor 386, the rewinding rack 387 can be driven to rewind the pull rope 388, so that the second electric push rod 383 can be moved away from the extension tube 121, and thus will not affect the rotation and downward exploration of the extension tube 121.

An alarm 47 is provided on the top surface of the electric control box 41.

[0056] Through the electrical control box 41 in the control mechanism 4, the bracket 43 can be installed on the stable frame 37 in the support mechanism 3, and the control circuit board 44, touch display screen 45, emergency button 46 and alarm 47 can be installed in conjunction with the box door 42. Through the touch display screen 45, the control circuit board 44 can be cooperated with to control the operation of the motor 21, the first electric push rod 375, the second electric push rod 383, the forward and reverse motor 386 and other equipment. When problems occur in the motor 21, the first electric push rod 375, the second electric push rod 383, the forward and reverse motor 386 and other equipment, by pressing the emergency button 46, the operation of the above-mentioned electrical equipment can be shut down through the control circuit board 44, thereby ensuring the safety of the equipment operation. At the same time, the control circuit board 44 can be turned on for operation, thereby serving the purpose of warning and reminder.

[0057] During use: through the support mechanism 3, it can be stably and firmly erected in the designated position, and can also provide an installation foundation for the driving mechanism 2 and the control mechanism 4. Then, through the driving mechanism 2, the drilling mechanism 1 can be installed and the drilling mechanism 1 can be driven to rotate at high speed. Under the telescopic lifting and lowering of the support mechanism 3, the driving mechanism 2 and the drilling mechanism 1 can be synchronously driven to move up and down, so that the drilling mechanism 1 can drill into the geology and store the drilled samples inside it. By continuously expanding and extending the drilling mechanism 1, the drilling mechanism 1 can sample a large number of samples at one time, thereby ensuring the stratification stability of each geological mineral material during sampling. This can greatly reduce the tedious operation of the staff to replace the drill bit and the collection device back and forth, and reduce the labor intensity of the staff. At the same time, through the upward movement of the support mechanism 3, the drilling mechanism 1 can be synchronously driven to move upward, so that the user can conveniently lift the drilling mechanism 1, thereby improving the sampling efficiency of the user.

[0058] The driving shaft 112 in the drilling mechanism 1 can be connected to the output end of the driving mechanism 2 through the first flange plate 111, and can provide space for the positioning slot 113 and the guide hole 114. At the same time, the oil filling pipe 115 can be installed so that it can be connected to the guide hole 114. Through the positioning slot 113, it can be engaged with the first clamping tube 122 on the extension tube 121. Through the engagement of the two, the driving mechanism 2 can simultaneously drive the first clamping tube 122 to rotate while driving the first flange plate 111 to rotate. Through the plug-in slot 124 at the bottom end of the first clamping tube 122, it can be engaged with the second clamping tube 133 on the sampling tube 131, and by rotating the ladder The limiting screw 126 in the screw hole 125 can make one end of the limiting screw 126 be inserted into the second limiting hole 134 on the second clamping tube 133, so that the sampling tube 131 and the extension tube 121 can be connected together, and then the sampling tube 131 can be driven to rotate synchronously while the extension tube 121 rotates. Since the bottom end of the sampling tube 131 is provided with a toothed ring 132, when the sampling tube 131 rotates, the geology can be drilled under the rotation of the toothed ring 132, so that the sampling tube 131 can be probed downward, and the first clamping tube 122 on the extension tube 121 can also be engaged with the plug-in slot 124 on the other extension tube 121, and by rotating the upper step of the other extension tube 121 The limiting screw 126 in the ladder screw hole 125 can make one end of the limiting screw 126 engage in the first limiting hole 123, so that multiple extension tubes 121 can be stacked and extended in sequence, thereby increasing the depth of the sampling tube 131, and the sample will continuously enter the sampling tube 131 and the extension tube 121, which is convenient for the sample to accumulate inside, so that samples of various geological layers can be obtained at one time, which greatly improves the integrity of the sample and the sampling efficiency. When a certain number of extension tubes 121 are extended, an appropriate amount of lubricant is injected into the oil filling tube 115, so that the lubricant can be injected into the extension tube 121 at the top through the guide hole 114, thereby making the lubricant The lubricant flows downward along the top extension tube 121, so that the lubricant can penetrate most of the extension tube 121, so as to reduce the friction between the sample and the inner wall of the extension tube 121, and facilitate the upward accumulation of the sample in each extension tube 121. The first sealing ring 127 and the second sealing ring 135 can ensure the connection sealing effect when the extension tube 121 and the drive shaft 112 and the sampling tube 131 and the extension tube 121 or multiple extension tubes 121 are connected. The annular groove 128 on the outer wall of the extension tube 121 can be used to support this place when the support mechanism 3 is raised, thereby driving the extension tube 121 to move upward, and then the extension tube 121 can be pulled out, so that the user can take out the downward extension tube 121.

[0059] Through the motor 21 and the eccentric gearbox 22 in the drive mechanism 2, it can be installed at the specified position of the support mechanism 3, and the motor 21 can drive the eccentric gearbox 22 to operate, so that the drive shaft 23 can rotate at high speed, and then can synchronously drive the second flange plate 24 to rotate. Since the second flange plate 24 is detachably connected to the first flange plate 111 through the first connecting bolt 25, when the second flange plate 24 rotates, it can synchronously drive the first flange plate 111 to rotate, so that the drive shaft 23 can drive the drive shaft 112 to rotate, and then can provide a rotational driving force for the sampling tube 131.

[0060] The triangular support plate 31 in the supporting mechanism 3 can provide a stable foundation for the motor 21 and the eccentric gearbox 22, and can also provide space for the through hole 32, and can also install and fix the three outer tubes 33. Since the inner cavity of each outer tube 33 is plugged with an inner tube 34, and the bottom surface of the inner cavity of the inner tube 34 is provided with an electric hydraulic telescopic rod, and the top of the telescopic end of the electric hydraulic telescopic rod is connected to the top of the inner cavity of the outer tube 33, the outer tube 33 can be synchronously driven to move on the inner tube 34 through the extension and contraction of the electric hydraulic telescopic rod, thereby adjusting the height of the use position of the triangular support plate 31. The three bases 35 can be fixed to the bottom ends of the three inner tubes 34 respectively, and the anchor rods 36 can be used to fix the base 35 to the ground, thereby improving the stability of the base 35 in use, so as to enhance the support of the inner tube 34. In order to ensure the stability of the support, the stabilizing frame 37 can be installed on the three outer tubes 33 and can be rolled to fit the outer wall of the extension tube 121, which can further improve the supporting stability of the three outer tubes 33 and provide limited support for the extension tube 121, thereby improving the rotation stability of the extension tube 121. The three ejector members 38 can be fixed on the three outer tubes 33 respectively and can be adjusted when the extension tube 121 needs to be pulled out, so that the telescopic end of the ejector member 38 can be against the annular groove 128. Through the extension of the electric hydraulic telescopic rod, the outer tube 33 can be driven upward, and the ejector member 38 can be driven upward synchronously. At this time, the ejector member 38 against the annular groove 128 will synchronously drive the extension tube 121 to move upward, thereby making it convenient for the user to smoothly remove the extension tube 121.

[0061] The three stabilizing sleeves 371 in the stabilizing frame 37 can be installed on the three outer tubes 33 respectively, and the three stabilizing sleeves 371 can be connected into a whole through the three connecting rods 372. By rotating the fixing screws 374 on the internal threaded holes 373, the stabilizing sleeves 371 can be fixed on the outer tube 33, and the position height of the stabilizing sleeves 371 on the outer tube 33 can be flexibly adjusted, thereby improving the convenience of equipment use and the stability of the support of the three outer tubes 33. The first electric push rod 375 can be installed on the connecting rod 372 and can drive the position of the bracket 376 installed at its telescopic end. Since the middle position of the top surface of the bracket 376 is provided with a first electric push rod 375, the first electric push rod 375 can be installed on the connecting rod 372 and can drive the position of the bracket 376 installed at its telescopic end. A ball groove 377 is provided, and a second ball groove 379 is also provided in the middle position of the bottom surface of the holder 378 above the bracket 376. At the same time, the bracket 376 and the holder 378 are connected together by a second connecting bolt 3711. Therefore, the combination of the first ball groove 377 and the second ball groove 379 can not only install the ball 3710, but also enable the ball 3710 to roll in its inner cavity. At this time, the first electric push rod 375 is extended, so that the ball 3710 can be attached to the outer wall of the extension tube 121, thereby supporting and limiting the rotating extension tube 121, thereby improving the rotation stability of the extension tube 121.

[0062] The positioning plate 381 in the ejector 38 can be fixed to the outer wall of the outer tube 33, and the second electric push rod 383 can be movably installed through the double-ear fixing seat 382. At the same time, the forward and reverse motor 386 can be installed through the mounting bracket 385. Since the reeling rack 387 on the output end of the forward and reverse motor 386 can be connected to the pull sleeve 389 on the second electric push rod 383 through the pull rope 388, and the telescopic end of the second electric push rod 383 is connected with the top tongue 384, when it is necessary to pull out the extension tube 121, the reeling rack 387 can unwind the pull rope 388 through the unwinding of the forward and reverse motor 386, so that the second electric push rod 383 can rotate around the axis of the double-ear fixing seat 382 until it reaches the appropriate position. At this time, the forward and reverse motor 386 stops unwinding. By extending and retracting the second electric push rod 383, the tongue 384 can be pressed against the annular groove 128, so that the two can be engaged with each other. Then, by extending the electric hydraulic telescopic rod, the outer tube 33 can be driven to move upward, and the outer tube 33 can synchronously drive the ejection member 38 to move upward as a whole, so that the tongue 384 on the ejection member 38 can be pulled upward against the extension tube 121, reducing the upward traction force of the eccentric gearbox 22 on the drive shaft 112 when the extension tube 121 is pulled upward, thereby improving the safety of the eccentric gearbox 22. Conversely, by rewinding the forward and reverse motor 386, the rewinding rack 387 can be driven to rewind the pull rope 388, so that the second electric push rod 383 can be moved away from the extension tube 121, and thus will not affect the rotation and downward exploration of the extension tube 121.

[0063] Through the electric control box 41 in the control mechanism 4, it can be installed on the stable frame 37 in the support mechanism 3 through the bracket 43, and can also cooperate with the box door 42 to install the control circuit board 44, touch display screen 45, emergency button 46 and alarm 47. Through the touch display screen 45, it can cooperate with the control circuit board 44 to control the operation of the motor 21, the first electric push rod 375, the second electric push rod 383, the forward and reverse motor 386 and other equipment. When the motor 21, the first electric push rod 375, the second electric push rod 383, the forward and reverse motor 386 and other equipment have problems, at this time, by pressing the emergency button 46, the operation of the above-mentioned electrical equipment can be shut down through the control circuit board 44, thereby ensuring the safety of the equipment operation. At the same time, the control circuit board 44 can be turned on for operation, thereby serving the purpose of warning and reminder.
