Description

Technical Field

[0001] The invention relates to the technical field of gear transmission devices, and in particular to a gear transmission device for ultra-deep foundation pit grouting liquid level monitoring equipment. Background Art

[0002] The gear transmission device is a mechanical device of ultra-deep foundation pit grouting level monitoring equipment that launches magnetic sheets through a hydraulically driven gear structure.

[0003] In the prior art, during the grouting construction process, the working surface is very complicated, the foundation pit depth reaches more than 200m, and it is filled with mud. The traditional manual pull-type scale line monitoring equipment completely relies on human perception to obtain data, and has problems such as poor measurement accuracy and many wire harnesses that are easy to be entangled. In addition, by monitoring the changes in the grouting material flow rate in the grouting conduit, indirectly monitoring or releasing mechanical waves to detect cracks in the formed grouting column to indirectly reflect the grouting process, it is easy to cause different degrees of engineering damage, and the transmission monitoring equipment will be invisible to the mud liquid above the ultra-deep foundation pit grouting material liquid surface, which will cause the problem of limited signal transmission distance. At present, the monitoring of the change of the grouting material level is carried out through manual scale line pulling equipment. This equipment is prone to cause the scale line to be entangled with the grouting conduit, and the lack of experience in manual scale line pulling leads to inaccurate monitoring results. The present invention aims to provide a gear transmission mechanism that can be used in ultra-deep foundation pit grouting surface monitoring equipment. The grouting surface monitoring equipment is suspended on the contact surface between the grouting material and the mud. The gear transmission mechanism can drive itself to emit a magnetic sheet to the outside world through the pressure change of the liquid surface where the monitoring equipment is located. After the sheet floats up, it reaches the top of the mud liquid column. The grouting material level is calculated through subsequent image recognition, thereby solving the problem of inaccurate accuracy of traditional monitoring equipment. Summary of the invention

[0031] In this embodiment, the gear transmission part 300 is driven by the rod fan gear 204 of the pressure driving part. When the monitoring equipment sinks in the mud, the metal membrane structure 201 of the pressure driving part 200 is compressed and deformed, driving the hinged end of the metal curved rod 202 to move downward. According to the lever principle, the rod fan gear 204 rotates counterclockwise around the rod fan gear limiting column 312, driving the right large spur gear 304 on the right limiting column 305 to rotate clockwise.

The present invention is mainly based on Bourdon tube structure, and its sturdy structure and large measuring range are suitable for ultra-deep foundation pit grouting level measurement, and its internal gear transmission mechanism has a simple structure, safe and reliable operation, and has high application value.

[0032] Example 2: Reference Figure 7-9 As shown: a drill bit 500 is provided at the bottom of the lower shell 101, a fixing rod 503 is fixedly installed on the top surface of the drill bit 500, an insert block 504 is inserted inside the drill bit 500, and the insert block 504 is internally rotatably connected to a limiting rod 505, a fixing hole 502 is provided on the bottom surface of the lower shell 101, and a limiting rod 505 is provided on the bottom surface of the lower shell 101, the fixing rod 503 is connected to the fixing hole 502 by a thread, the insert block 504 is slidably connected to the drill bit 500, and the limiting rod 505 is connected to the limiting hole 501 by a thread, and the number of the limiting holes 501, the limiting rod 505 and the insert block 504 is four groups, and the four groups of limiting holes 501 are evenly distributed at the bottom of the lower shell 101, and the four groups of insert blocks 504 and the limiting rod 505 are evenly distributed inside the drill bit 500.

[0033] In this embodiment, by rotating the limiting rod 505, after the limiting rod 505 is rotated out of the limiting hole 501, the insert block 504 together with the limiting rod 505 can be pulled out from the drill bit 500. At this time, the drill bit 500 is rotated again, and the fixing rod 503 is driven to rotate when the drill bit 500 rotates. After the fixing rod 503 is rotated out of the fixing hole 502, the drill bit 500 can be removed from the lower housing 101, and then a new drill bit 500 is connected to the fixing hole 502 through the fixing rod 503. After the fixing rod 503 is connected After that, the insert block 504 is inserted into the drill bit 500, and the limit rod 505 is rotated at this time. After the limit rod 505 is connected with the limit hole 501, the drill bit 500 can be replaced. When it is necessary to monitor the grouting liquid level inside the foundation pit, the drill bit 500 is most seriously worn during the sinking process of the lower shell 101. The replaceable design of the drill bit 500 avoids the need to replace the entire drill bit 500 when it is seriously damaged, thereby saving the maintenance cost of the gear transmission device.

[0034] The use method and working principle of the device are as follows: when the monitoring equipment sinks in the mud liquid, the metal film of the pressure driving part 200 is compressed and deformed, driving the hinged end of the metal curved rod 202 to move downward. According to the lever principle, the rod fan gear 204 rotates counterclockwise around the rod fan gear limiting column 312, driving the right large spur gear 304 on the right limiting column 305 to rotate clockwise. The movable pinion 302, which is restricted by the pinion fixing short rod 311 and is in the middle arc-shaped limiting groove 303, rotates counterclockwise and disengages from the right large spur gear 304 on the right limiting column 305. The left large spur gear 308 on the left limiting column 307 and the bottom bevel gear 306 remain stationary under the limiting action of the L-shaped limiting lever 301.

[0035] When the monitoring device is suspended on the contact surface between the grouting material and the mud liquid and rises with it, the metal membrane structure 201 is affected by the hydraulic pressure of the mud column above, and the metal membrane structure 201 will gradually return to its original state and drive the hinged end of the metal curved rod 202 to move upward. At this time, the rod-belt fan gear 204 rotates clockwise, driving the right large spur gear 304 on the right limit column 305 to rotate counterclockwise. At this time, the movable small gear 302 returns to the bottom of the arc-shaped limit groove 303 under the action of gravity, meshing with the left limit column 308 and the right limit column 30 5 and the right large spur gear 304 rotate clockwise, the left large spur gear 308 on the left limit column 307 rotates counterclockwise driven by the movable pinion 302, and the bottom bevel gear 306 meshing with the transmission bevel gear 309 on the left limit column 307 rotates clockwise, and the magnetic sheet storage turntable 401 of the gear transmitting part 400 can be driven by the threaded transmission rod 402 and the bottom bevel gear 306 of the gear transmitting part 300 is driven by the ball bearing 403 to rotate stably;

[0036] The magnetic sheet storage turntable 401 placed in the turntable storage grid and the annular array magnetic strip 404 embedded in the monitoring device will produce the same magnetic force repelling each other. When the magnetic sheet storage turntable 401 rotates with the bottom bevel gear 306, the magnetic sheet storage turntable 401 coincides with the magnetic sheet launching slot 102 on the conical arc surface of the lower half of the device, and the magnetic sheet can be launched out of the device;

[0037] Through the image recognition and calculation equipment installed externally, the color of the magnetic sheets released within different pressure ranges can be identified, and the liquid level of the monitoring equipment can be determined by calculation, that is, the specific position where the grouting material liquid level rises;

[0038] The gear transmission part 300 is installed in the monitoring device suspended on the contact surface of the high-density grouting material and the low-density mud, and drives the gear mechanism to launch a floating thin sheet through the liquid pressure acting on the surface of the instrument, so as to achieve the monitoring effect of the grouting material level, and the transmission mechanism can drive itself to launch a magnetic thin sheet to the outside world through the pressure change of the liquid surface where the monitoring device is located. After the thin sheet floats up, it reaches the top of the mud liquid column, and the grouting material level is calculated through subsequent image recognition, which solves the problem of inaccurate accuracy of traditional monitoring equipment and fully improves the construction quality of the grouting project. In addition, the mechanical gear structure adopts hydraulic drive, which can also meet the grouting liquid level monitoring construction environment of the deep groove of more than 200 meters, avoiding the situation that the traditional manual pull-type scale line monitoring equipment completely relies on human perception to obtain data, and also solves the problems of poor measurement accuracy of the transmission monitoring equipment and easy entanglement of many wire harnesses. The present invention is mainly based on the Bourdon tube structure, and its sturdy structure and large range are suitable for ultra-deep foundation pit grouting level measurement, and its internal gear transmission mechanism has a simple structure, safe and reliable operation, and has a high application value.

[0039] When the drill bit 500 needs to be replaced, it is only necessary to rotate the limit rod 505. After the limit rod 505 is rotated out of the limit hole 501, the insert block 504 together with the limit rod 505 can be pulled out from the drill bit 500. At this time, the drill bit 500 is rotated again. When the drill bit 500 is rotated, the fixing rod 503 is driven to rotate. After the fixing rod 503 is rotated out of the fixing hole 502, the drill bit 500 can be removed from the lower shell 101, and then a new drill bit 500 is connected to the fixing hole 502 through the fixing rod 503. After fixing the rod 503, the insert block 504 is inserted into the drill bit 500. At this time, the limit rod 505 is rotated. After the limit rod 505 is connected to the limit hole 501, the drill bit 500 can be replaced. When it is necessary to monitor the grouting liquid level inside the foundation pit, the drill bit 500 is most severely worn during the sinking of the lower shell 101. The replaceable design of the drill bit 500 avoids the need to replace the entire drill bit 500 when it is seriously damaged, thereby saving the maintenance cost of the gear transmission device.
