Coal mine surveying and mapping marker post device

Abstract

The utility model relates to the field of surveying and mapping equipment, in particular to a coal mine surveying and mapping marker post device which comprises an outer marker post, an inner marker post arranged in the outer marker post, a fixing mechanism used for inserting the outer marker post on the ground and a cleaning mechanism used for cleaning the inner marker post. The connecting rod is turned over through movement of the movable frame to move the inserting plate in the direction away from the outer marker post, then the fixing cone is separated from locking and stretches out of the outer marker post, then the inserting plate is inserted again to lock the fixing cone and insert the fixing cone into the ground, and therefore the fixing cone can be prevented from scratching a carrying person in the marker post carrying process; dust attached to the inner marker post is scraped, swept and cleaned through the scraper, then the marker post pushes the piston rod to move towards the air replenishing cylinder to blow air into the sweeping cover through the air guide pipe, and the dust attached to the inner marker post is swept and cleaned through the sweeping cover. Therefore, the situation that dust enters the outer marker post and consequently the inner marker post is difficult to pull out is avoided.

Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping equipment, in particular to a coal mine surveying and mapping benchmark device. Background Art

[0002] A search of the patent document with publication number CN218297173U shows that the rod and slider are fixed to the base by loosening the nut to place the crossbar in the limiting slot, and the rod is inserted into the ground to secure the entire device. The clamping block is then pulled out of the second slot using a push-pull rod, and the marking rod is then pulled out of the second mounting sleeve. The clamping block is then reinserted into the second slot to secure the marking rod.

[0003] This patent document discloses that during the entire use of the marker, there will be a large amount of powder in the coal mine environment, and there is a certain gap between the second mounting sleeve and the marker rod. Therefore, the powder will adhere to the outside of the pulled-out marker rod, and when the marker rod is inserted into the second mounting sleeve, it will follow it into the mounting sleeve. Over time, a large amount of powder will accumulate in the second mounting sleeve, which may cause the marker rod to get stuck when it is pulled out. At the same time, the attached powder may affect the observation of the scale of the marker rod, which may affect the progress of the entire coal mine surveying and mapping. In addition, most of the marker rods that can be inserted into the ground have a sharp end that is inserted into the ground, and then the person carrying the marker rod may be scratched during the entire carrying process, which is very dangerous.

The purge cover 44 is connected to the lower end of the air cylinder 41 through an air guide pipe 43. The purge cover 44 is fixed to the end close to the inner mark 2 with a scraper 45 for scraping off the dust attached to it. A strip-shaped air blowing port is provided on the inclined surface of the purge cover 44, and an air hole for suction is provided at the bottom of the air cylinder 41. The air suction spring is used to push the air cylinder 41 upward. The piston rod 42 in the air cylinder 41 pushes upward, and the upward movement of the piston rod 42 allows air to enter the air cylinder 41 through the air hole. At the same time, when the inner mark rod 2 retracts into the outer rod body 11, the scraper 45 is used to scrape off the dust attached to the inner mark rod 2. At the same time, the inner mark rod 2 moves downward to push the piston rod 42 into the air cylinder 41, and then squeezes the air in the air cylinder 41. The squeezed air enters the purge cover 44 through the air guide pipe 43, and the outer side of the inner mark rod 2 is blown through the strip-shaped air blowing port on the purge cover 44 to remove the attached dust.

When the cam 35 is unlocked, the locking cam 36 is unlocked and the locking cam 36 is unlocked. When the cam 35 is unlocked, the locking cam 36 is unlocked, and the locking cam 36 is unlocked.

[0036] When the cam 33 is in the closed position, the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam 33 is in the closed position, and the cam 33 is in the closed position, so that the cam That is, push the lower plug plate 34 to insert into the interior of the outer rod body 11 and cooperate with the annular groove of the fixing cone 36, then lock the fixing cone 36, and at the same time, the rubber cone head at the upper end of the fixing cone 36 disengages the seal of the air hole at the bottom of the air refilling cylinder 41, and the air hole at the bottom of the air refilling cylinder 41 is opened; then insert the fixing cone 36 extending from the lower end of the outer rod body 11 into the ground, and then pull the locking magnet 14 to move in the limit cover 13, so that the wedge-shaped strip of the locking magnet 14 disengages from the wedge-shaped groove of the inner mark rod 2, and at this time pull the inner mark rod 2 out of the outer rod body 11, and the pulled inner mark rod 2 is released from the downward pressure on the piston rod 42, and the suction spring will push the piston rod 42 upward, and the upward moving piston rod 42 will draw air in from the air hole;

[0037] When the inner rod 2 is pulled out of the outer rod body 11 by a certain length, the locking magnet 14 is released and the outer rod 2 is re-adsorbed to the side of the bracket 12 by the magnetic force of the locking magnet 14. Then, the wedge-shaped strip on the locking magnet 14 is matched with the wedge-shaped groove of the inner rod 2, and the inner rod 2 is re-locked.

[0038] When the surveying is completed, the fixed cone 36 at the bottom of the outer rod body 11 is pulled out of the ground, and then the mobile frame 31 is pushed again to move the plug plate 34 outward through the connecting rod 33, so that the plug plate 34 is released from the clamping of the annular groove of the fixed cone 36, and then the fixed cone 36 is pressed against the ground, and the outer rod body 11 is pressed down to retract the fixed cone 36 into its interior, and then the mobile frame 31 is loosened and the two plug plates 34 are reinserted into the interior of the outer rod body 11, and the annular groove on the fixed cone 36 is clamped by the plug plate 34. During the process, the rubber conical head on the fixing cone 36 is used to seal the air hole at the bottom of the air cylinder 41, and then the locking magnet 14 is pulled to release it from the fixation on the inner rod 2, and the inner rod 2 is pressed back into the outer rod body 11, and the piston rod 42 is pushed by the inner rod 2. The piston rod 42 moves downward in the air cylinder 41, so that the air inside the air cylinder 41 enters the purge cover 44 from the air guide pipe 43, and the dust attached to the outside of the inner rod 2 is blown away through the strip-shaped air blowing port on the purge cover 44;

[0039] In addition, when the inner rod 2 is pressed back into the outer rod body 11 , the scraper 45 is used to scrape and clean the dust attached to the inner rod 2 .
