Description

Technical Field

[0001] The invention relates to the technical field of hoists, and in particular to a load measuring device for a mine hoist. Background Art

[0002] In the daily production process of mines, hoists are one of the commonly used mechanical equipment. Hoists are usually used to transfer raw materials and equipment to designated locations. At the same time, during the use of hoists, workers need to test the load and weight of different types of hoists to prevent the hoist from being overloaded and causing failure during use.

[0003] The patent with the patent announcement number CN216846498U discloses a load measuring device for a mining hoist, which relates to the technical field of hoists, including a base, wherein a plurality of cylinders are fixedly connected inside the base, and a plurality of connecting blocks are fixedly connected to the side of the base, a connecting platform is fixedly connected between the plurality of cylinders, a load measuring structure is embedded and connected to the upper surface of the connecting platform, and an adjustment column is provided through the plurality of connecting blocks, a rotating platform is slidably connected to one side of the output end of the plurality of adjustment columns, and a fixed platform is fixedly connected to the output end of the plurality of adjustment columns and located on the upper side of the rotating platform. The load measuring device of the patent has a simple structure and can be installed at the bottom of the hoist, and the stability of the device during use can be improved by the base and the reinforcement of the main bottom of the adjustment. During measurement, the static state of the hoist can be detected by the first infrared sensing structure on the rotating platform and the second infrared sensing structure on the fixed platform.

[0004] However, the device still has some shortcomings: the device can measure the load of the elevator, but when the weight of the elevator carrying overweight materials exceeds the bearing range of the hydraulic push component of the measuring equipment during the measurement process, the hydraulic push component is prone to sudden fall when it remains in a static measuring state after rising, which is easy to cause damage to the equipment and pose a certain danger to the staff. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a load measuring device for a mining hoist, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a load measuring device for a mining hoist, including a device body, information modules are arranged on the front and back of the device body, an alarm component is arranged on the periphery of the information module, and the alarm component is arranged on the outer wall of the device body, four electric hydraulic rods are fixedly installed at the bottom corners of the inner wall of the device body, the four electric hydraulic rods are composed of a fixed end and a telescopic end, the four electric hydraulic rods are grouped in two, and the two groups of electric hydraulic rods are symmetrically distributed around the axis of the device body, a load-bearing plate is fixedly installed on the top of the telescopic end of the electric hydraulic rod, and the load-bearing plate is fixedly installed on the top of the telescopic end of the electric hydraulic rod. An electrical weighing sensor is arranged inside the weight plate, a load measuring assembly is fixedly installed on the top of the load-bearing plate, two circular plates are hinged at the bottom edge of the load-bearing plate, and the two circular plates are symmetrically distributed with respect to the axis of the device body, an L-shaped push plate is hinged at the bottom of the circular plate, a reset plate is fixedly installed on the side of the L-shaped push plate close to the center of the device body, a T-shaped arc plate is penetrated and slidably installed inside the L-shaped push plate, a spring is fixedly installed between the circular surface of the outer wall of the T-shaped arc plate and the outer wall of the L-shaped push plate, a number of semi-arc blocks are fixedly installed on the front and back of the inner wall of the device body, the electric hydraulic rod is started, and the telescopic end of the electric hydraulic rod When it rises, the load-bearing plate is pushed upward, and the load-bearing plate drives the load-measuring component to move synchronously. The load-measuring component contacts the bottom of the material conveying component of the elevator and pushes it up. After rising, the telescopic end of the electric hydraulic rod remains stationary for weight detection; when the telescopic end of the electric hydraulic rod carries overweight materials that exceed the maximum weight that the telescopic end of the electric hydraulic rod can bear, the telescopic end of the electric hydraulic rod is prone to malfunction and suddenly falls down, and the telescopic end of the electric hydraulic rod pulls the load-bearing plate to fall synchronously. When the load-bearing plate falls, it hits the top of the circular plate. At this time, the bottom of the circular plate is limited by the L-shaped push plate, causing the hinge shaft at the top of the circular plate to start rotating. The L-shaped push plate is moved, and the return plate pushes the L-shaped push plate to slide along the bottom of the inner wall of the device main body toward the center of the device main body. The two ends of the L-shaped push plate resist the deformation toward the center direction of the reset plate. The reset plate gradually increases the resistance to the L-shaped push plate during the deformation process. At the same time, the L-shaped push plate drives the T-shaped arc plate to move synchronously. During the movement of the T-shaped arc plate, it will resist the arc surface of the semi-arc block to generate a resistance force. At this time, one end of the round surface of the T-shaped arc plate slides toward the inside of the L-shaped push plate. Since the thrust of the return plate is greater than the elastic force of the spring and the spring is limited by the outer wall of the L-shaped push plate, the T-shaped arc plate is caused to resist the deformation of the spring during the sliding process, and the spring drives the T-shaped arc plate to reset through elastic reset.

[0007] According to the above technical solution, the bottom of the L-shaped push plate is slidably installed on the bottom of the inner wall of the device body, a number of the semi-arc blocks are equidistantly distributed on the inner wall of the device body, and the arc surface of the semi-arc block is located on the movement trajectory of the T-shaped arc plate, and anti-interference devices are provided on the left and right sides of the device body for expanding the contact area between the device body and the ground when the electric hydraulic rod is raised.

[0008] According to the above technical scheme, the anti-interference device includes a plurality of transmission plates, a fixed seat and a hollow plate, the tops of the plurality of transmission plates are hinged at the inclined surface of the outer wall of the circular plate, and the plurality of transmission plates are symmetrically distributed around the axis of the device body, the fixed seat is fixedly installed on the outer wall of the device body close to the outer wall of the electric hydraulic rod, the hollow plate is penetrated and slidably installed on the side of the fixed seat away from the device body close to the device body, and the circular plate will move away from the center of the device body when the load-bearing plate rises, and the circular plate pushes the transmission plate to move synchronously, and the bottom of the transmission plate is resisted by the hollow plate, causing the hinge shaft of the transmission plate to start rotating. At this time, the bottom of the transmission plate pushes the hollow plate to extend from the inside of the fixed seat away from the center of the device body.

[0009] According to the above technical scheme, the anti-interference device also includes a sliding wheel, a reciprocating screw, a plurality of rotating plates, an elastic telescopic rod, an L-shaped pressure plate and a hollow ring. The outer wall of the sliding wheel is rotatably installed at the edge of the inner wall of the hollow plate, and both ends of the reciprocating screw are fixedly installed on the sliding wheel near the center of the inner wall of the hollow plate. The reciprocating spiral groove on the surface of the reciprocating screw is opened at the center of the outer wall. Several rotating plates are equidistant and fixedly installed on the outer walls at both ends of the reciprocating screw. The top of the telescopic end of the elastic telescopic rod is fixedly installed on the top of the inner wall of the hollow plate, and the top of the L-shaped pressure plate is fixedly installed on the bottom of the fixed end of the elastic telescopic rod. The outer wall of the hollow ring penetrates and is fixedly installed at the inside and below of the L-shaped pressure plate. The outer wall of the hollow ring is located on the arc motion trajectory of the rotating plate, and the sliding wheel is driven synchronously when the hollow plate extends. The rotation of the reciprocating screw drives the rotating plate to rotate, and the rotating plate drives the rotating plate to rotate. The arc surface of the rotating plate continuously contacts the arc surface of the outer wall of the hollow ring to generate a resistance force during the rotation. The hollow ring drives the L-shaped pressure plate to move upward through the resistance force of the arc surface of the rotating plate and the guiding force of the arc surface. When the L-shaped pressure plate moves upward, it drives the telescopic end of the elastic telescopic rod to retract upward. When the rotating plate no longer contacts the hollow ring, the telescopic end of the elastic telescopic rod is reset through its own elasticity and pushes the L-shaped pressure plate to reset. When the elastic telescopic rod moves upward, it contracts and accumulates force. Therefore, during the resetting process, the elastic telescopic rod suddenly pushes the L-shaped pressure plate to hit the top of the conical column.

[0010] According to the above technical scheme, the anti-interference device also includes a fixed plate and a plurality of conical columns. The fixed plate is fixedly installed on the inner wall of the hollow plate away from the center of the reciprocating screw rod. The outer walls of the plurality of conical columns penetrate and are slidably installed inside the fixed plate. The top of the conical column contacts the top of the inner wall of the L-shaped pressure plate. An anti-blocking device is provided on the periphery of the hollow plate to prevent the hollow plate from being obstructed by ground obstacles when extending. The conical column moves downward, that is, toward the ground, through the limit of the fixed plate. At the same time, when the hollow plate moves, the conical column is caused to fall into the ground and can slide laterally to deepen the depth between the conical column and the ground.

[0011] According to the above technical scheme, the anti-blocking device includes a sliding plate, a cross plate, a plurality of sweeping plates and a connecting rod, wherein the sliding plate passes through and is slidably installed on the outer wall of the reciprocating spiral groove of the reciprocating screw rod near one end of the sliding plate near the fixed seat, and the plurality of sweeping plates are slidably installed on the outer wall of the hollow plate near one side of the fixed seat, and the outer wall of the connecting rod passes through and is fixedly installed between the plurality of sweeping plates. When the reciprocating screw rod rotates, the sliding plate is restricted by the non-self-locking reciprocating spiral groove on its own outer wall, and the blocking block arranged inside the sliding plate continuously contacts the inner wall of the reciprocating spiral groove, so that when the sliding plate slides back and forth along the outer wall of the reciprocating screw rod, it drives the cross plate to move synchronously along the inner wall of the hollow plate, and the cross plate resists the sweeping plate to slide synchronously along the outer wall of the hollow plate, and the plurality of sweeping plates achieve synchronous sliding through the connecting rod, and when the sweeping plate slides away from the center of the hollow plate, it resists the reset spring between itself and the hollow plate to cause deformation, and the elastic force of the reset spring pushes the sweeping plate to reset.

[0012] According to the above technical solution, the back side of the sliding plate is slidably installed on the back side of the inner wall of the hollow plate, a return spring is arranged between the sweeping plate and the hollow plate, and a U-shaped groove is arranged at the bottom of the sweeping plate.

[0013] According to the above technical scheme, the anti-blocking device also includes a cylinder, a power plate, a fixed rod, a plurality of hinged plates and a torsion plate. The left and right ends of the cylinder are rotatably installed on the inner wall of the U-shaped groove in the sweeping plate. The cylinder is designed to be thin on the left and thick on the right, and the right side of the outer wall of the cylinder is in contact with the ground. A spiral groove is opened on the left side of the outer wall of the cylinder. The power plate passes through and is slidably installed on the outer wall of the spiral groove of the cylinder. The top of the power plate is slidably connected to the top of the inner wall of the U-shaped groove of the sweeping plate. The fixed rod is fixedly installed on the outer wall of the sweeping plate near one side of the hollow plate. Several of the hinged plates are hinged on the outer wall surface of the fixed rod. Several of the hinged plates are symmetrically distributed around the axis of the fixed rod, and the inner wall of the hinged plate is located on the movement trajectory of the power plate. The side is fixed between the inclined surface of the outer wall of the hinge plate and the outer wall of the sweeping plate. When the sweeping plate slides, the outer wall of the thicker end of the cylinder on the right side inside the U-shaped groove of the sweeping plate contacts the ground and generates friction to start rotating. When the sweeping plate is reset, it drives the cylinder to reset and the cylinder rotates in the opposite direction. When the cylinder rotates forward and reverse, the non-self-locking spiral groove opened on the thinner outer wall on the left side of the cylinder restricts the power plate. At the same time, the internal block of the power plate contacts the inner wall of the spiral groove, so that the power plate slides left and right along the outer wall of the spiral groove of the cylinder. When the power plate slides to the left, it hits the inclined surface of the inner wall of the hinge plate to generate resistance. The fixed rod limits the hinge plate. The hinge shaft of the hinge plate starts to rotate through the resistance force and the hinge plate unfolds in an arc trajectory. When the hinge plate loses the resistance, it automatically resets through the torsion plate, and repeats this process.

[0014] The present invention provides a load measuring device for a mine hoist, which has the following beneficial effects:

[0015] (1) The present invention cooperates with an electric hydraulic rod, a load-bearing plate, a load-measuring component, a circular plate, an L-shaped push plate, a reset plate, a T-shaped arc plate, a spring and a semi-arc block, so that the load-measuring component sends a signal source through an information module, transmits the measured gravity data to a monitoring component on a mobile terminal in the hands of a worker and records the data. At the same time, when the load is overweight, the alarm component emits a harsh alarm to remind the worker to rush to the work site in time to avoid malfunction of the mining hoist; at the same time, when the electric hydraulic rod falls, the faster the falling speed is, the greater the deformation resistance of the reset plate is. At the same time, the multiple interference limits between the T-shaped arc plate and the semi-arc block further slow down and stabilize the falling phenomenon, preventing the hoist from collapsing due to uneven gravity distribution, thereby causing equipment damage and avoiding certain dangers to the workers.

[0016] (2) The present invention adopts the setting of anti-interference device, and cooperates with the circular plate, transmission plate, fixed seat, hollow plate, sliding wheel, reciprocating screw, rotating plate, elastic telescopic rod, L-shaped pressure plate, hollow ring, fixed plate and conical column to realize that when the load measurement component is raised and the material weight is detected, the contact area between the device body and the ground is expanded, thereby improving the stability during the load measurement process, preventing the center of gravity of the device from being unstable and shaking after the height is increased, thereby affecting the measurement accuracy; and promoting the rolling and extending hollow plate to reduce its own wear. At the same time, the hollow plate relies on the conical column to penetrate into the ground during the extension process to increase the overall stability of the device, thereby avoiding the vibration generated during the operation of large-scale equipment in the mine, which causes the device as a whole to continue to shake slightly, thereby further improving the measurement accuracy on the basis of the original stability.

[0017] (3) The present invention sets an anti-blocking device, and cooperates with a reciprocating screw, a sliding plate, a horizontal plate, a sweeping plate, a connecting rod, a cylinder, a power plate, a fixed rod, a hinged plate and a torsion plate to cause the sweeping plate to continuously sweep solid obstacles on the ground during its movement, thereby preventing solid particles from sinking into the bottom of the hollow plate during its extension. At this time, the solid particles increase the friction loss between the hollow plate and the ground during the movement of the hollow plate, shortening the maintenance and replacement cycle of the hollow plate. At the same time, a large amount of solid obstacles are easily accumulated, which can easily cause the hollow plate to warp. At the same time, the hinged plate is caused to swing and scrape off the solidified obstacles on the movement path of the hollow plate during the process of reciprocating expansion and resetting. The hinged plate effectively enhances the sweeping plate's ability to remove obstacles. At the same time, the reciprocating swing of the hinged plate expands the sweeping range of the sweeping plate and reduces the amount of dirt attached to the contact part of the sweeping plate and the obstacle.

[0028] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 9An embodiment of the present invention is: a load measuring device for a mining hoist, comprising a device body 1, information modules 2 are arranged on the front and back of the device body 1, an alarm component 3 is arranged on the periphery of the information module 2, and the alarm component 3 is arranged on the outer wall of the device body 1, four electric hydraulic rods 6 are fixedly installed at the bottom corners of the inner wall of the device body 1, the four electric hydraulic rods 6 are composed of a fixed end and a telescopic end, the four electric hydraulic rods 6 are grouped in two, and the two groups of electric hydraulic rods 6 are symmetrically distributed around the axis of the device body 1, a load-bearing plate 7 is fixedly installed on the top of the telescopic end of the electric hydraulic rod 6, an electric weighing sensor is arranged inside the load-bearing plate 7, a load measuring component 8 is fixedly installed on the top of the load-bearing plate 7, two round-shaped plates 9 are hinged at the bottom edge of the load-bearing plate 7, the two round-shaped plates 9 are symmetrically distributed around the axis of the device body 1, an L-shaped push plate 10 is hinged at the bottom of the round-shaped plate 9, and a reset plate 11 is fixedly installed on the side of the L-shaped push plate 10 close to the center of the device body 1, A T-shaped arc plate 12 is penetrated and slidably installed inside the L-shaped push plate 10, and a spring 13 is fixedly installed between the circular surface of the outer wall of the T-shaped arc plate 12 and the outer wall of the L-shaped push plate 10. A number of semi-arc blocks 14 are fixedly installed on the front and back of the inner wall of the device body 1. Through the above cooperation, the load measurement component 8 sends a signal source through the information module 2, and the measured gravity data is transmitted to the monitoring component of the mobile terminal in the hands of the staff and the data is recorded. At the same time, when the load is overweight, the alarm component 3 emits a piercing alarm to remind the staff to rush to the work site in time to avoid malfunction of the mining hoist; through the above cooperation, when the electric hydraulic rod 6 falls, the faster the falling speed is, the greater the deformation resistance of the reset plate 11 is encountered. At the same time, the multiple interference limits between the T-shaped arc plate 12 and the semi-arc blocks 14 further slow down and stabilize the falling phenomenon, preventing the hoist from collapsing due to uneven gravity distribution, thereby causing equipment damage, and avoiding certain dangers to the staff.

[0030] The bottom of the L-shaped push plate 10 is slidably installed on the bottom of the inner wall of the device body 1. A number of semi-arc blocks 14 are equidistantly distributed on the inner wall of the device body 1, and the arc surface of the semi-arc block 14 is located on the movement trajectory of the T-shaped arc plate 12. Anti-interference devices 4 are provided on the left and right sides of the device body 1 for expanding the contact area between the device body 1 and the ground when the electric hydraulic rod 6 is raised.

[0031] When in use, the electric hydraulic rod 6 is started. When the telescopic end of the electric hydraulic rod 6 rises, the load-bearing plate 7 is pushed upward, and the load-bearing plate 7 drives the load-measuring component 8 to move synchronously. The load-measuring component 8 contacts the bottom of the material conveying component of the elevator and pushes it up. After rising, the telescopic end of the electric hydraulic rod 6 remains stationary for weight detection, and the load-bearing plate 7 transmits the pressure applied by the load-measuring component 8 to the electrical load-bearing sensor inside itself. The electrical load-bearing sensor measures the force of the object by checking the load borne by the force carrier, and converts the force into a corresponding electrical signal for measurement and recording monitoring. The load measurement component 8 is prompted to send a signal source through the information module 2, and the measured gravity data is transmitted to the monitoring component of the mobile terminal in the hands of the staff and the data is recorded. At the same time, when the load is overweight, the alarm component 3 sends a harsh alarm to remind the staff to rush to the work site in time to avoid malfunction of the mine hoist; when the telescopic end of the electric hydraulic rod 6 carries overweight materials exceeding the maximum weight that the telescopic end of the electric hydraulic rod 6 can bear, the telescopic end of the electric hydraulic rod 6 is prone to malfunction and suddenly falls down, and the telescopic end of the electric hydraulic rod 6 pulls the load-bearing plate 7 to fall synchronously, and the load-bearing plate 7 hits the top of the circular plate 9 when it falls. At this time, the bottom of the return plate 9 is limited by the L-shaped push plate 10, which causes the hinge shaft at the top of the return plate 9 to start rotating, and the return plate 9 pushes the L-shaped push plate 10 to slide along the bottom of the inner wall of the device body 1 toward the center of the device body 1. The L-shaped push plate 10 resists the two ends of the reset plate 11 and deforms toward the center. The reset plate 11 gradually increases the resistance to the L-shaped push plate 10 during the deformation process. At the same time, the L-shaped push plate 10 drives the T-shaped arc plate 12 to move synchronously. During the movement of the T-shaped arc plate 12, it will resist the arc surface of the semi-arc block 14 to generate a resistance force. At this time, one end of the round surface of the T-shaped arc plate 12 slides toward the inside of the L-shaped push plate 10. The thrust of the circular plate 9 is greater than the elastic force of the spring 13 and the spring 13 is limited by the outer wall of the L-shaped push plate 10, which causes the T-shaped arc plate 12 to resist the deformation of the spring 13 during the sliding process. After that, the spring 13 drives the T-shaped arc plate 12 to reset through elastic reset. Through the above cooperation, when the electric hydraulic rod 6 falls, the faster the falling speed is, the greater the deformation resistance of the reset plate 11 is encountered. At the same time, the multiple resistances and limits between the T-shaped arc plate 12 and the semi-arc block 14 further slow down and stabilize the falling phenomenon, preventing the elevator from collapsing due to uneven gravity distribution, thereby causing equipment damage and avoiding certain dangers to the staff.

[0032] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-interference device 4;

[0033] The anti-interference device 4 includes a plurality of transmission plates 41, a fixed seat 42 and a hollow plate 43. The tops of the plurality of transmission plates 41 are hinged at the inclined surface of the outer wall of the circular plate 9. The plurality of transmission plates 41 are symmetrically distributed around the axis of the device body 1. The fixed seat 42 is fixedly installed on the outer wall of the device body 1 close to the outer wall of the electric hydraulic rod 6. The hollow plate 43 penetrates through the side close to the device body 1 and is slidably installed on the side of the fixed seat 42 away from the device body 1. Through the above configuration, when the load measurement component 8 is raised and the material weight is detected, the contact area between the device body 1 and the ground is expanded, thereby improving the stability during the load measurement process, and preventing the device from shaking due to the unstable center of gravity after the height is increased, thereby affecting the measurement accuracy.

[0034] The anti-interference device 4 also includes a sliding wheel 44, a reciprocating screw rod 45, a plurality of rotating plates 46, an elastic telescopic rod 47, an L-shaped pressure plate 48 and a hollow ring 49. The outer wall of the sliding wheel 44 is rotatably mounted on the edge of the inner wall of the hollow plate 43. Both ends of the reciprocating screw rod 45 are fixedly mounted on the sliding wheel 44 near the center of the inner wall of the hollow plate 43. The reciprocating spiral groove on the surface of the reciprocating screw rod 45 is opened at the center of the outer wall. A plurality of rotating plates 46 are equidistant and fixedly mounted on the outer walls at both ends of the reciprocating screw rod 45. The top of the telescopic end of the elastic telescopic rod 47 is fixedly mounted on the top of the inner wall of the hollow plate 43. The top of the L-shaped pressure plate 48 is fixedly mounted on the bottom of the fixed end of the elastic telescopic rod 47. The outer wall of the hollow ring 49 passes through and is fixedly mounted on the inside and below of the L-shaped pressure plate 48. The outer wall of the hollow ring 49 is located on the arc motion trajectory of the rotating plate 46.

[0035] The anti-interference device 4 also includes a fixed plate 410 and a plurality of conical columns 411. The fixed plate 410 is fixedly installed on the inner wall of the hollow plate 43 away from the center of the reciprocating screw rod 45. The outer walls of the plurality of conical columns 411 penetrate and are slidably installed inside the fixed plate 410. The top of the conical column 411 contacts the top of the inner wall of the L-shaped pressure plate 48. An anti-blocking device 5 is arranged on the periphery of the hollow plate 43 to prevent the hollow plate 43 from being obstructed by ground obstacles when extending. Through the above cooperation, the rolling and extending hollow plate 43 reduces its own wear. At the same time, the hollow plate 43 relies on the conical column 411 to penetrate into the ground during the extension process to increase the overall stability of the device, avoid the vibration generated during the operation of large equipment in the mine, and cause the overall device to continue to shake slightly, thereby further improving the measurement accuracy on the basis of the original stability.

[0036] When in use, the circular plate 9 will move away from the center of the device body 1 when the load-bearing plate 7 rises, and the circular plate 9 pushes the transmission plate 41 to move synchronously. The bottom of the transmission plate 41 is resisted by the hollow plate 43, causing the hinge shaft of the transmission plate 41 to start rotating. At this time, the bottom of the transmission plate 41 pushes the hollow plate 43 to extend from the inside of the fixed seat 42 away from the center of the device body 1. Through the above configuration, when the load measurement component 8 is raised and the material weight is detected, the contact area between the device body 1 and the ground is expanded, thereby improving the load measurement process. The stability in the middle is prevented to prevent the center of gravity of the device from being unstable and shaking after the height is increased, thereby affecting the measurement accuracy; when the hollow plate 43 is extended, it drives the sliding wheel 44 to move synchronously and contact and rub with the ground, and the sliding wheel 44 starts to rotate through the friction force. When the sliding wheel 44 rotates, the sliding friction between the hollow plate 43 and the ground is converted into rolling friction. At the same time, the sliding wheel 44 drives the reciprocating screw rod 45 to rotate, and when the reciprocating screw rod 45 rotates, it drives the rotating plate 46 to rotate. The arc surface of the rotating plate 46 continuously contacts the arc surface of the outer wall of the hollow ring 49 during the rotation process to generate a resistance force. The hollow ring 49 pushes the L-shaped pressing plate 48 upward through the resistance force of the arc surface of the rotating plate 46 and the guiding force of the arc surface. When the L-shaped pressing plate 48 moves upward, the telescopic end of the elastic telescopic rod 47 contracts upward. When the rotating plate 46 no longer resists the hollow ring 49, the telescopic end of the elastic telescopic rod 47 is reset by its own elasticity and pushes the L-shaped pressing plate 48 to reset. When the elastic telescopic rod 47 moves upward, it contracts and accumulates force. Therefore, during the resetting process, the elastic telescopic rod 47 suddenly pushes the L-shaped pressing plate 48 to hit the top of the conical column 411, and the conical column 411 is retracted. The fixed plate 410 is limited to move downward, that is, toward the ground. At the same time, the hollow plate 43 moves so that the conical column 411 can slide horizontally to deepen the depth between the hollow plate 43 and the ground after falling into the ground. The above cooperation can reduce the wear of the hollow plate 43 that rolls and extends. At the same time, the hollow plate 43 relies on the conical column 411 to go deep into the ground during the extension process to increase the stability of the device as a whole, avoid the vibration generated by the operation of large equipment in the mine, and cause the device as a whole to continue to shake slightly, thereby further improving the measurement accuracy on the basis of the original stability.

[0037] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-blocking device 5;

[0038] The anti-blocking device 5 includes a sliding plate 51, a cross plate 52, a plurality of sweeping plates 53 and a connecting rod 54. The sliding plate 51 is inserted into the inner part of one end close to the fixed seat 42 and is slidably installed on the outer wall of the reciprocating spiral groove of the reciprocating screw rod 45. The plurality of sweeping plates 53 are slidably installed on the outer wall of the hollow plate 43 on one side close to the fixed seat 42. The outer wall of the connecting rod 54 is inserted into and fixedly installed between the plurality of sweeping plates 53. Through the above cooperation, the sweeping plate 53 is prompted to continuously sweep the solid obstacles on the ground during the movement, preventing the solid particles from sinking into the bottom of the hollow plate 43 during the extension process. At this time, the solid particles increase the friction loss between the hollow plate 43 and the ground during the movement of the hollow plate 43, shortening the maintenance and replacement cycle of the hollow plate 43. At the same time, when a large amount of solid obstacles are accumulated, it is easy to cause the hollow plate 43 to warp.

[0039] The back side of the sliding plate 51 is slidably mounted on the back side of the inner wall of the hollow plate 43 , a return spring is arranged between the sweeping plate 53 and the hollow plate 43 , and a U-shaped groove is arranged at the bottom of the sweeping plate 53 .

[0040] The anti-blocking device 5 also includes a cylinder 55, a power plate 56, a fixed rod 57, a plurality of hinged plates 58 and a twisting plate 59. The left and right ends of the cylinder 55 are rotatably mounted on the inner wall of the U-shaped groove in the sweeping plate 53. The cylinder 55 is designed to be thin on the left and thick on the right, and the right side of the outer wall of the cylinder 55 is in contact with the ground. A spiral groove is provided on the left side of the outer wall of the cylinder 55. The power plate 56 penetrates the inside and is slidably mounted on the outer wall of the spiral groove of the cylinder 55. The top of the power plate 56 is slidably connected to the top of the inner wall of the U-shaped groove of the sweeping plate 53. The fixed rod 57 is fixedly mounted on the outer wall of the sweeping plate 53 near the side of the hollow plate 43. The plurality of hinged plates 58 are hinged on the outer wall of the fixed rod 57. On the surface, several hinged plates 58 are symmetrically distributed around the axis of the fixed rod 57, and the inner wall of the hinged plate 58 is located on the movement trajectory of the power plate 56. The torsion plate 59 is fixedly installed between the outer wall inclined surface of the hinged plate 58 and the outer wall of the sweeping plate 53 close to the side of the fixed rod 57. Through the above cooperation, the hinged plate 58 is swung and scraped to remove the solidified obstacles on the movement path of the hollow plate 43 during the process of reciprocating expansion and resetting. The hinged plate 58 effectively enhances the sweeping plate 53's ability to clear obstacles. At the same time, the reciprocating swing of the hinged plate 58 expands the sweeping range of the sweeping plate 53 and reduces the amount of dirt attached to the contact part of the sweeping plate 53 with the obstacle.

[0041] When in use, the reciprocating screw 45 is rotated by limiting the sliding plate 51 through the non-self-locking reciprocating spiral groove on its outer wall, and the block arranged inside the sliding plate 51 continuously contacts the inner wall of the reciprocating spiral groove, so that when the sliding plate 51 slides back and forth along the outer wall of the reciprocating screw 45, it drives the cross plate 52 to move synchronously along the inner wall of the hollow plate 43, and the cross plate 52 resists the sweeping plate 53 and slides synchronously along the outer wall of the hollow plate 43. The multiple sweeping plates 53 achieve synchronous sliding through the connecting rod 54, and when the sweeping plate 53 slides in the direction away from the center of the hollow plate 43, it resists itself and the hollow plate 4 3 is deformed, and the elastic force of the reset spring pushes the sweeping plate 53 to reset, and the above cooperation causes the sweeping plate 53 to continuously sweep the solid obstacles on the ground during its movement, preventing solid particles from sinking into the bottom of the hollow plate 43 during its extension. At this time, the solid particles increase the friction loss between the hollow plate 43 and the ground during the movement of the hollow plate 43, shortening the maintenance and replacement cycle of the hollow plate 43. At the same time, when a large amount of solid obstacles are accumulated, it is easy to cause the hollow plate 43 to warp. When the sweeping plate 53 slides, the U-shaped groove inside itself The outer wall of the thicker end of the right side of the cylinder 55 contacts the ground and generates friction to start rotating. When the sweeping plate 53 is reset, it drives the cylinder 55 to reset and the cylinder 55 rotates in the opposite direction. When the cylinder 55 rotates forward and reversely, the non-self-locking spiral groove on the thinner outer wall on the left side of the cylinder 55 restricts the power plate 56. At the same time, the internal block of the power plate 56 contacts the inner wall of the spiral groove, so that the power plate 56 slides left and right along the outer wall of the spiral groove of the cylinder 55. When the power plate 56 slides to the left, it contacts the inclined surface of the inner wall of the hinge plate 58 to generate a resistance force. The fixing rod 57 limits the hinge plate 58. The hinge shaft 58 starts to rotate due to the resistance force and the hinge plate 58 unfolds in an arc trajectory. When the hinge plate 58 loses the resistance force, it is automatically reset through the torsion plate 59, and this process is repeated repeatedly. Through the above cooperation, the hinge plate 58 is caused to swing and scrape the solidified obstacles on the movement path of the hollow plate 43 during the process of reciprocating expansion and reset. The hinge plate 58 effectively enhances the clearing force of the sweeping plate 53 on the obstacles. At the same time, the reciprocating swing of the hinged plate 58 expands the sweeping range of the sweeping plate 53 and reduces the amount of dirt attached to the contact part of the sweeping plate 53 with the obstacle.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
