Description

Technical Field

[0001] The present invention relates to the technical field of sensor calibration, and more specifically, to a sensor lifting device. Background Art

[0002] During the process of mine excavation, sensors need to be installed on the top of the mine to detect the mine. As the mine is excavated, the number of sensors installed in the mine is gradually increasing. In order to ensure the accuracy of sensor detection, the sensors need to be calibrated regularly. During the calibration, people need to climb to the top of the mine with tools such as ladders, and then remove the sensors for calibration. After the calibration, people need to climb to the top of the mine with tools such as ladders to install the sensors. During the calibration process, people need to frequently climb up and down with the help of tools, which wastes a lot of manpower in the calibration process. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a sensor lifting device, which, when calibrating the sensor, releases the limit on the pull rope, and under the action of its own gravity, the fixing mechanism moves downward near one end of the pull rope, so that the sensor can be manually removed from the fixing mechanism and calibrated. After the calibration, the pull rope is pulled, so that the fixing mechanism near the stretched end rises to the top of the mine and fixes the pull rope. There is no need for frequent manual climbing up and down, saving a lot of manpower.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a sensor lifting device, comprising a fixing mechanism, on which the sensor is fixed;

[0005] A hanging mechanism, which is used to fix one end of the fixing mechanism to the top of the mine;

[0006] and a hoisting mechanism, which is used to hoist the fixing mechanism to the top of the mine;

[0007] The lifting mechanism comprises a pull rope. When the pull rope is pulled, the pull rope drives the fixing mechanism to move upward, and the position of the pull rope can be fixed.

[0008] By adopting the above technical solution, the sensor is fixed on the end of the fixing mechanism close to the pull rope. When the sensor needs to be calibrated, the limit of the pull rope is loosened. Under the action of the fixing mechanism's own gravity, the fixing mechanism moves downward close to the end of the pull rope. The sensor on the fixing mechanism can be removed for calibration without climbing to the top of the mine. After the calibration, the sensor is installed on the fixing mechanism, and then the pull rope is pulled to make the fixing mechanism move close to the top of the mine where one end of the pull rope moves, and then the pull rope is fixed. The entire calibration process does not require frequent manual climbing up and down, which greatly saves manpower.

[0009] The present invention is further configured as follows: the hoisting mechanism further comprises a fixed pulley, which is arranged at the top of the mine cave, and the pull rope passes around the top of the fixed pulley and contacts the top of the fixed pulley;

[0010] And a winch, on which one end of the pull rope facing away from the fixing mechanism is wound.

[0011] The present invention is further configured as follows: the lifting mechanism includes a fixing plate, which is fixed at a position close to the top of the mine cave;

[0012] A storage tray is rotatably connected to the fixed plate, and an end of the pull rope facing away from the suspension mechanism is wound around the storage tray;

[0013] And a power assembly, which is used to drive the storage tray to rotate on the fixed plate.

[0014] The present invention is further configured as follows: a matching hole is provided on a side of the storage tray close to the power assembly;

[0015] The power assembly includes a telescopic rod, which extends into the matching hole and can drive the storage tray to rotate;

[0016] A power shaft, which is provided with a telescopic hole for accommodating the telescopic rod near one end of the telescopic rod and can drive the telescopic rod to rotate;

[0017] And an elastic member, which is arranged in the telescopic hole and is used for pushing the telescopic rod into the matching hole.

[0018] By adopting the above technical solution, under the action of the elastic member, the telescopic rod extends into the matching hole, thereby driving the storage plate to rotate through the power shaft to complete the winding of the pull rope; when calibration is required, a long rod is used to push the telescopic rod out of the matching hole, the pull rope is free from restriction, and under the action of the fixing mechanism's own gravity, the fixing mechanism approaches one end of the pull rope and pulls it downward together.

[0019] The present invention is further configured as follows: the matching hole passes through the storage tray, the matching hole is vertically arranged, and the power shaft is located at the top of the matching hole.

[0020] By adopting the above technical solution, the matching hole is vertically arranged, which makes it easy to manually insert the long rod into the matching hole to push the telescopic rod.

[0021] The present invention is further configured as follows: the suspension mechanism includes a fixing member, which is arranged at one end of the fixing mechanism away from the suspension mechanism and fixed to the top of the mine cave;

[0022] a suspension rope, which is fixedly connected to the fixing member and passes through the fixing mechanism;

[0023] And a winding component, which is used for winding the suspension rope.

[0024] By adopting the above technical solution, when the fixing mechanism moves downward near one end of the pull rope, the winding assembly releases the winding of the suspension rope, and the end of the fixing mechanism near the fixing part moves downward under the action of the fixing mechanism's own gravity, thereby eliminating the need to fix the sensor on the fixing mechanism near one end of the pull rope, so that the sensors can be arranged more evenly on the fixing mechanism.

[0025] The present invention is further configured as follows: the fixing mechanism comprises a telescopic tube and a fixing tube;

[0026] The fixed pipe sleeve is arranged in the telescopic pipe, and the telescopic pipe extends from one end of the fixed pipe away from the fixing piece.

[0027] By adopting the above technical solution, the telescopic rod can be slid to adjust the length of the fixing mechanism according to the number of sensors to be set.

[0028] The present invention is further configured as follows: the suspension rope passes through the fixed tube and the telescopic tube, and the winding assembly is arranged on the telescopic tube.

[0029] The present invention is further configured as follows: at least one slide groove is opened on the inner side of the fixed tube, a slider capable of sliding in the slide groove along the length direction of the slide groove is arranged in the slide groove, an elastic member that pushes the slider to slide in a direction away from the fixed member is arranged on the side of the slider close to the fixed member, and the slider is fixedly connected to the telescopic tube.

[0030] By adopting the above technical solution, the winding assembly winds up the suspension rope and can push the telescopic tube to be inserted into the fixed tube. The winding assembly gradually loosens the winding of the suspension rope, and under the action of the elastic member, the telescopic tube gradually extends out from the fixed tube.

[0031] The present invention is further configured as follows: the elastic member includes a guide tube and a sliding rod;

[0032] The sliding direction of the sliding rod in the guide tube is parallel to the sliding direction of the slider, the contact between the sliding rod and the guide tube is sealed, and air or liquid is sealed in the guide tube;

[0033] The ends of the guide tube and the sliding rod which are away from each other are fixedly connected to the sliding block and the fixed tube respectively.

[0034] In summary, compared with the prior art, the present invention has the following beneficial effects: the sensor of the present invention is fixed on one end of the fixing mechanism close to the pull rope. When the sensor needs to be calibrated, the limit on the pull rope is loosened. Under the action of the gravity of the fixing mechanism itself, the fixing mechanism moves downward close to one end of the pull rope. The sensor on the fixing mechanism can be removed for calibration without climbing to the top of the mine. After the calibration, the sensor is installed on the fixing mechanism, and then the pull rope is pulled to make the fixing mechanism move close to the top of the mine where one end of the pull rope moves, and then the pull rope is fixed. The entire calibration process does not require frequent manual climbing up and down, which greatly saves manpower. BRIEF DESCRIPTION OF THE DRAWINGS

The ends of the guide tube 141 and the sliding rod 142 that face away from each other are fixedly connected to the slider 121 and the fixed tube 11 respectively; specifically, in this embodiment, the end of the guide tube 141 that faces away from the sliding rod 142 is fixedly connected to the fixed tube 11 on the side of the slide groove 111 close to the baffle 33, and the end of the sliding rod 142 that extends out of the guide tube 141 is fixedly connected to the side of the slider 121 close to the baffle 33.

[0062] See attached Figure 7 In this embodiment, the winding assembly 32 includes two winding plates 321 fixedly connected to the telescopic tube 12, a winding roller 322 arranged between the two winding plates 321 and rotatably connected to the two winding plates 321, and a handle for rotating the winding roller 322; preferably, both ends of the winding roller 322 are fixedly connected with a rotating rod 323 coaxial with the winding roller 322, and the two rotating rods 323 respectively pass through the two winding plates 321; the handle includes a rotating plate 324 fixedly connected to one of the rotating rods 323 and a holding rod 325 fixedly connected to the side of the rotating plate 324 away from the winding roller 322.

When the winch 24 winds up the pull rope 21, the fixed mechanism 1 can be lifted near one end of the pull rope 21, and when the winch 24 relaxes the winding of the pull rope 21, the fixed mechanism 1 moves downward near one end of the pull rope 21 under the gravity of the fixed mechanism 1 itself.

The end of the pull rope 21 away from the fixed pipe 11 is wound on the storage tray 22. The power assembly drives the storage tray 22 to rotate, thereby realizing the winding operation of the pull rope 21.

[0066] In this embodiment, the axis of the storage tray 22 is vertically arranged, and a matching hole 221 is provided on the storage tray 22 and passes through the storage tray 22 along the axis direction of the storage tray 22; the power assembly includes a power shaft 26 driven by a motor and coaxial with the storage tray 22, a telescopic rod 27 arranged in the power shaft 26 and capable of extending from the power shaft 26 into the matching hole 221, and an elastic member 262 arranged in the power shaft 26 for pushing the telescopic rod 27 to extend into the matching hole 221.

[0067] A telescopic hole 261 is provided at one end of the power shaft 26 close to the rotating disk, and the telescopic rod 27 can be completely inserted into the telescopic hole 261, and the telescopic rod 27 slides in the telescopic hole 261 in the vertical direction. When the telescopic rod 27 extends into the matching hole 221 under the elastic action of the elastic member 262, the telescopic rod 27 can drive the storage disk 22 to rotate together. When the pull rope 21 needs to be wound up, the power shaft 26 drives the storage disk 22 to rotate through the telescopic rod 27 to achieve the winding of the pull rope 21. When the storage disk 22 needs to relax the winding of the pull rope 21, the operator inserts the long rod into the matching hole 221 and pushes the telescopic rod 27 out of the matching hole 221, so that the rotating disk can rotate freely, so that under the action of the gravity of the fixing mechanism 1, the rotating disk is driven to relax the stretched winding.

[0068] See attached Fig.10At least one power slot 222 is provided on the side wall of the matching hole 221 along the axis direction of the matching hole 221. A power block 271 corresponding to the power slot 222 is fixedly connected to the outside of the telescopic rod 27. The power slot 222 penetrates the storage tray 22 upward. When the telescopic rod 27 is inserted into the matching hole 221, the power block 271 is inserted into the corresponding power slot 222. During the rotation of the telescopic rod 27, the storage tray 22 is pushed to rotate by the power block 271.

When the anti-slip block 272 moves to the bottom of the anti-slip groove 264, the telescopic rod 27 is prevented from being separated from the power shaft 26 by the limiting action of the part of the power shaft 26 at the bottom of the anti-slip groove 264. In this embodiment, there are two anti-slip grooves 264 and two anti-slip blocks 272.

[0071] In this embodiment, a top plate 28 is fixedly connected to the top of the mine, and a plurality of fixing rods 281 fixedly connected to the fixing plate 25 are fixedly connected to the top plate 28. The motor is fixedly connected to the bottom of the top plate 28 and is located between the top plate 28 and the fixing plate 25.

[0072] The working principle of the sensor lifting device when in use is as follows: the sensor is installed on the fixing mechanism 1. When calibration is required, the storage tray 22 first loosens the winding of the pull rope 21. Under the action of the gravity of the fixing mechanism 1 itself, the end of the fixing mechanism 1 close to the pull rope 21 moves downward, and then the winding component 32 loosens the winding of the suspension rope 31. Under the action of the gravity of the fixing mechanism 1 itself, the fixing mechanism 1 moves downward close to the baffle 33. The operator can directly remove the sensor for calibration. After the calibration is completed, the suspension rope 31 is first wound up by the winding component 32, and the end of the fixing mechanism 1 close to the top plate 28 moves upward. Then, the pull rope 21 is wound up by the storage tray 22, and the end of the fixing mechanism 1 close to the pull rope 21 is pulled upward.

[0073] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
