Description

Technical Field

[0001] This invention relates to the field of stacker technology, specifically to a walking and rotating positioning device for an automated bulk material moving stacker. Background Technology

[0002] Material storage and transfer are generally carried out in the form of open-air stockyards. Stacker cranes are important stacking operation equipment. Tire-mounted mobile cantilever stacker cranes are large, continuous, and efficient bulk material handling machinery. They use fixed moving tracks and their main function is to stack the goods unloaded by the unloader onto the stockyard for easy access by the reclaimer. Currently, they are mainly used in coal and ore storage yards in industries such as power, metallurgy, building materials, and chemicals.

[0003] The shortcomings of existing walking and rotating positioning devices are:

[0004] 1. Patent document JP4553821B2 discloses a backhoe that "can easily pipe hydraulic hoses from control valves to rotary joints and can be easily maintained. A turntable is rotatably mounted on the travel frame of the traveling body via a rotary bearing, and a rotary joint is located at the center of the rotary bearing, with a device supported on the turntable." This backhoe lacks a positioning structure, cannot position the turntable after angle adjustment, and cannot guarantee the stability of the turntable during use.

[0005] 2. Patent document JP2000204592A discloses a stepped installation structure for construction machinery. "This invention provides a stepped installation structure for construction machinery, allowing the operator to approach the vicinity of the operating valve for the hydraulic actuator driving the vehicle or work machine in a stable posture, facilitating the inspection and maintenance of the operating valve, rotating machinery, and their peripheral equipment. The inspection step 12 is positioned approximately midway between the operating valve 10 and the rotating machinery 9. Additionally, the upper rotating body..." This stepped installation structure has a relatively simple positioning structure, cannot adjust the positioning range of the positioning structure, and cannot meet the positioning requirements of different installation structures.

[0006] 3. Patent document JP2003171085A discloses a self-propelled operating machine: "This invention provides a self-propelled crane that can make the vehicle width narrower while ensuring as much cab space as possible. It has a freely undulating multi-stage telescopic boom (2e) on the upper frame (2a) and a freely rotatable upper rotating body (2) formed by setting the cab (2h), and a self-propelled crane (1) having a lower traveling vehicle body (4) that rotatably supports the upper rotating body (2)." This self-propelled operating machine cannot lubricate the driving structure while positioning the traveling and slewing drive structure, and cannot guarantee the good performance of the drive structure.

[0007] 4. Patent document CN216371237U discloses an automatic rotary positioning device for mechanical clamps, "including a base, a fixing frame, the fixing frame being installed on the top side of the base, a central shaft passing through the middle of the fixing frame, and a disc being installed at one end of the central shaft, a clamping block being slidably connected to the middle of one side of the disc, and mounting plates being connected to both the upper and lower ends of the clamping block, a first strip-shaped opening being opened on the outer side of the base, and a sleeve being inserted into the inner side of the first strip-shaped opening, and a telescopic mechanism being inserted into the inner side of the sleeve." In this utility model, the arc-shaped sleeve, which forms a detachable structure with bolts and a disc, allows the operator to align the arc-shaped sleeve with the second mounting hole on the disc according to the type and size of the workpiece being clamped, based on the desired positioning position of the workpiece. This improves the practicality of the device. However, this rotary positioning device cannot filter and clean impurities and oil residue in the lubricating fluid. Lubricating oil containing impurities and oil residue can easily damage the mechanical clamp, failing to guarantee a good lubricating effect. Summary of the Invention

[0011] Preferably, the lifting drive assembly includes a cylinder, a connecting plate is installed at the output end of the cylinder, a connecting rod is installed on the outer side of the connecting plate, and the outer end of the connecting rod is connected to the outer side of the positioning frame.

[0012] Preferably, the bottom of the positioning frame has a motor movable cavity, which is connected to the storage cavity. A lubricating oil storage cavity is located at the center of the positioning frame, with an oil supply pipe connected to its input end. Several flow holes are formed on the side of the positioning frame away from the lifting drive assembly, and these flow holes are connected to the lubricating oil storage cavity. An anti-scratch pad is installed on the outer side of the positioning frame. An installation groove is formed on the inner wall of the flow holes, and a flow rate detector is installed inside the installation groove. An insertion groove is formed on the top of the positioning frame, and it is connected to the flow holes. Installation holes are symmetrically arranged on the inner side of the positioning frame, with a through-hole between the installation hole and the storage cavity. An electric telescopic rod is installed on the inner wall of the installation hole, and the output end of the electric telescopic rod passes through the inside of the through-hole. A limit groove is formed on the inner wall of the storage cavity. A groove is formed on the outer side of the positioning frame, and a distance sensor is installed inside the groove.

[0013] Preferably, the auxiliary positioning component includes an auxiliary positioning arc plate, a fixed arc plate, and a limiting circular plate. The fixed arc plate is installed on the inner side of the auxiliary positioning arc plate, and an adjusting screw is installed through the outer side of the fixed arc plate. A locking motor is installed on the outer side of the auxiliary positioning arc plate, and the output end of the locking motor is connected to the input end of the adjusting screw. A limiting circular plate is installed on the output end of the adjusting screw. An annular groove is formed on the outer side of the limiting circular plate, and a contact sensing coil is installed on the inner side of the annular groove.

[0014] Preferably, a plug-in frame is installed on the inner side of the plug-in slot, a filter screen is installed on the inner side of the plug-in frame, a slag collection part is provided on the inner side of the plug-in frame and the slag collection part is located on the outer side of the filter screen, a sealing gasket is installed on the outer side of the plug-in frame, and an operating pull block is installed on the top of the plug-in frame.

[0015] Preferably, a fixed seat is symmetrically installed on the top of the positioning frame, a sleeve is installed on the top of the fixed seat, a lifting rod is installed on the inner side of the sleeve, a limit stud is installed through the outer side of the sleeve, and the limit stud is used to limit the lifting rod. A fixed plate is installed on the top of the lifting rod, a top positioning post is installed on the bottom of the fixed plate, and the bottom end of the top positioning post is in contact with the top of the plug-in frame.

[0016] Preferably, an intelligent controller is installed on the outside of the adjustment frame. The intelligent controller has a receiving module installed inside, which receives the output signals from the contact sensor, distance sensor, and flow rate detector. The input of the receiving module is connected to a walking and turning mechanism output module, which outputs control signals for the walking and turning mechanism. The output of the receiving module is connected to an alarm module, which alerts the monitoring personnel. The output of the receiving module is connected to a time storage module, which records the operation duration of the walking and turning positioning device. The intelligent controller also has a control module installed inside, which drives and controls the installation adjustment component, lifting drive component, tire drive shaft positioning component, and auxiliary positioning component. The output of the time storage module is connected to a data analysis module, which analyzes the operation duration of the walking and turning positioning device and assists in controlling the control module.

[0017] Preferably, the working steps of the rotary positioning device are as follows:

[0018] S1. First, install the two sets of rotary positioning devices symmetrically below the drive box of the stacker's traveling rotary mechanism using mounting bolts. The contact sensor contacts the bottom of the drive box and works. After the stacker's traveling rotary mechanism finishes working, the signal is transmitted to the intelligent controller through the traveling rotary mechanism output module. The intelligent controller controls the lifting drive component to work. The cylinder pushes the connecting plate, causing the connecting rod to drive the tire drive shaft positioning component to adjust its position in the vertical direction.

[0019] S2. After the height of the tire drive shaft positioning assembly is adjusted, the intelligent controller controls the adjustment motor to run and drive the threaded rod to rotate. The rotation of the threaded rod causes the adjustment plate to move inside the sliding groove, which in turn drives the lifting drive assembly and the tire drive shaft positioning assembly to move horizontally. The limit rod ensures the stability of the adjustment plate when it moves.

[0020] S3. The distance sensor detects the distance between the tire drive shaft positioning assembly and the stacker traveling slewing mechanism drive shaft. When the anti-scratch pad of the positioning frame is detected to be in contact with the outside of the drive shaft, the distance sensor transmits the signal to the intelligent controller, and the intelligent controller controls the adjustment motor to stop working.

[0021] S4. The intelligent controller controls the electric telescopic rod to push the auxiliary positioning arc plate, causing it to slide and move downward inside the limit groove. After the auxiliary positioning arc plate moves into place, the locking motor runs, driving the adjusting screw to rotate and causing the limit plate to screw in towards the drive shaft and clamp the outside of the drive shaft. When the contact induction coil contacts the outside of the drive shaft, the contact induction coil transmits a signal to the intelligent controller, which then controls the locking motor to stop working.

[0022] Preferably, step S1 further includes the following steps:

[0023] S11. As the usage time of the walking and turning positioning device increases, a gap will be generated between the mounting plate and the bottom of the drive box. When the gap reaches the maximum preset range, the contact sensor will transmit a signal to the intelligent controller. The intelligent controller will then alert the background monitoring personnel through the warning module, reminding the staff to tighten the installation and adjustment components.

[0024] Step S4 further includes the following steps:

[0025] S41. The intelligent controller controls the lubricating oil extraction drive module to work, which enables the external oil supply equipment to work. The oil supply equipment transmits lubricating oil through the oil pipe to the lubricating oil storage chamber. After the oil supply equipment has worked for a preset time, it automatically stops running. The lubricating oil in the lubricating oil storage chamber flows out through the flow hole and seeps into the anti-scratch pad to lubricate the outside of the drive shaft and the connection.

[0026] S42. The filter screen filters and removes oil residue and impurities from the lubricating oil. The removed oil residue and impurities accumulate in the slag collection section. The flow rate detector detects the flow rate of the lubricating oil flowing through the flow hole. When the flow rate value is less than the preset range, it indicates that the oil residue and impurities have caused the filter screen to be blocked. The intelligent controller alerts the background monitoring personnel through the warning module, reminding the staff to clean the filter screen.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] This invention features a tire drive shaft positioning component installed at the output end of the lifting drive assembly. A cylinder pushes a connecting plate, causing a connecting rod to adjust the vertical position of the tire drive shaft positioning component. After the tire drive shaft positioning component is adjusted, an intelligent controller controls a regulating motor to rotate a threaded rod. This rotation moves the regulating plate within a sliding groove, causing the lifting drive assembly and the tire drive shaft positioning component to move horizontally. A distance sensor detects the distance between the tire drive shaft positioning component and the drive shaft of the stacker's traveling and rotating mechanism. When the anti-scratch pad of the positioning frame contacts the outside of the drive shaft, the distance sensor transmits a signal to the intelligent controller. The intelligent controller then stops the regulating motor, ensuring the stability of the traveling and rotating mechanism during operation by positioning the drive shaft after angle adjustment.

[0029] This invention utilizes an auxiliary positioning component located inside the storage cavity. An intelligent controller controls an electric telescopic rod to push an auxiliary positioning arc plate, causing it to slide and move downwards within a limiting groove. Once the auxiliary positioning arc plate is in position, a locking motor drives an adjusting screw to rotate, causing the limiting disc to screw in towards the drive shaft and clamp the outer side of the drive shaft. When the contact induction coil contacts the outer side of the drive shaft, it transmits a signal to the intelligent controller, which then stops the locking motor. This adjustment of the positioning range of the positioning component further stabilizes the traveling and rotating mechanism.

[0030] This invention features a lubricating oil storage chamber located at the center of the positioning frame. The oil supply device delivers lubricating oil to the storage chamber via an oil pipe. After a preset operating time, the oil supply device automatically stops operating. The lubricating oil in the storage chamber flows out through a flow hole and seeps into the anti-scratch pad to lubricate the outer side of the drive shaft and its connection points. This invention positions the traveling and rotating drive structure while simultaneously lubricating the drive shaft, ensuring good performance of the drive shaft and extending its service life.

[0031] This invention features a plug-in frame installed inside the plug-in slot. A filter screen filters and removes oil residue and impurities from the lubricating oil. The removed oil residue and impurities accumulate in the slag collection section. A flow rate detector monitors the flow rate of the lubricating oil flowing through the flow hole. When the flow rate is less than a preset range, it indicates that oil residue and impurities are clogging the filter screen. The intelligent controller alerts the monitoring personnel via an alarm module. Rotating the limit screw releases the limit on the lifting rod, and adjusting the height of the lifting rod disengages the top positioning post from the top of the plug-in frame, facilitating the cleaning of the filter screen and impurities by the staff.

A sliding groove 15 is formed on the inner wall of the adjustment frame 11, and the outer side of the adjustment plate 14 is fitted into the inner side of the sliding groove 15. A limit rod 17 is installed on the inner side of the adjustment frame 11, and the limit rod 17 penetrates the inner side of the adjustment plate 14. First, the two sets of return... The positioning device uses mounting bolts 9 to symmetrically install the mounting adjustment assembly 1 below the drive box of the stacker's traveling and rotating mechanism to achieve positioning of the outer side of the drive shaft. The contact sensor 10 contacts and works with the bottom of the drive box. As the traveling and rotating positioning device is used for longer periods, a gap will be generated between the mounting plate 8 and the bottom of the drive box. When the gap reaches the maximum preset range, the contact sensor 10 transmits a signal to the intelligent controller 7. After the tire drive shaft positioning assembly 3 is adjusted in height, the intelligent controller 7 controls the adjustment motor 13 to run and drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 causes the adjustment plate 14 to move inside the sliding groove 15, which in turn drives the lifting drive assembly 2 and the tire drive shaft positioning assembly 3 to move horizontally. The intelligent controller 7 controls the adjustment motor 13 to stop working, and the limit rod 17 ensures the stability of the adjustment plate 14 when it moves.

After the oil supply equipment has been working for a preset time, it automatically stops. The lubricating oil in the lubricating oil storage cavity 24 flows out through the flow hole 26 and seeps into the anti-scratch pad 27 to lubricate the outer side of the drive shaft and the connection of the drive shaft, thus lubricating the travel and rotation drive. While positioning the structure, the drive shaft is lubricated. Mounting groove 28 provides a mounting position for flow rate detector 29. A insertion groove 30 is provided on the top of positioning frame 21, communicating with flow hole 26. Mounting holes 31 are symmetrically arranged on the inner side of positioning frame 21.

After the stacker's traveling and rotating mechanism completes its operation, it transmits a signal to the intelligent controller 7 through the traveling and rotating mechanism output module. As the travel and rotating positioning device is used for longer periods, a gap will form between the mounting plate 8 and the bottom of the drive box. When the gap reaches the maximum preset range, the contact sensor 10 transmits a signal to the intelligent controller 7. The intelligent controller 7 alerts the background monitoring personnel via the warning module, reminding them to tighten the installation adjustment component 1. The flow rate detector 29 detects the flow rate of the lubricating oil. When the flow rate is less than the preset range, it indicates that oil residue and impurities have clogged the filter screen 45. The intelligent controller 7 alerts the background monitoring personnel via the warning module, prompting them to disassemble and clean the filter screen 45. The time storage module records the positioning time of the rotating positioning device. The data analysis module provides auxiliary control of the working status of the drive components based on the recorded time, making the positioning process smoother. It can also indirectly detect the working status of the components inside the rotating positioning device through the positioning time, ensuring that the rotating positioning device maintains good working performance at all times.

[0056] The working steps of this rotary positioning device are as follows:

[0057] S1. First, the two sets of rotary positioning devices are installed symmetrically below the drive box of the stacker's traveling rotary mechanism using mounting bolts 9. The contact sensor 10 contacts the bottom of the drive box and works. After the stacker's traveling rotary mechanism finishes working, the signal is transmitted to the intelligent controller 7 through the traveling rotary mechanism output module. The intelligent controller 7 controls the lifting drive component 2 to work. The cylinder 18 runs and pushes the connecting plate 19, causing the connecting rod 20 to drive the tire drive shaft positioning component 3 to adjust its position in the vertical direction.

[0058] S2. After the height of the tire drive shaft positioning assembly 3 is adjusted, the intelligent controller 7 controls the adjustment motor 13 to run and drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 causes the adjustment plate 14 to move inside the sliding groove 15, which in turn drives the lifting drive assembly 2 and the tire drive shaft positioning assembly 3 to move horizontally. The limit rod 17 ensures the stability of the adjustment plate 14 when it moves.

[0059] S3. The distance sensor 36 detects the distance between the tire drive shaft positioning assembly 3 and the drive shaft of the stacker traveling and rotating mechanism. When the anti-scratch pad 27 of the positioning frame 21 is detected to be in contact with the outside of the drive shaft, the distance sensor 36 transmits the signal to the intelligent controller 7, and the intelligent controller 7 controls the adjustment motor 13 to stop working.

[0060] S4. The intelligent controller 7 controls the electric telescopic rod 32 to push the auxiliary positioning arc plate 37, causing the auxiliary positioning arc plate 37 to slide and move downward inside the limiting groove 33. After the auxiliary positioning arc plate 37 moves into place, the locking motor 39 runs, driving the adjusting screw 40 to rotate, causing the limiting circular plate to screw in towards the drive shaft and clamp the outside of the drive shaft. When the contact induction coil 43 contacts the outside of the drive shaft, the contact induction coil 43 transmits a signal to the intelligent controller 7, and the intelligent controller 7 controls the locking motor 39 to stop working.

[0061] Step S1 also includes the following steps:

[0062] S11. As the usage time of the walking and turning positioning device increases, a gap will be generated between the mounting plate 8 and the bottom of the drive box. When the gap reaches the maximum preset range, the contact sensor 10 will transmit a signal to the intelligent controller 7. The intelligent controller 7 will warn the background monitoring personnel through the warning module, reminding the staff to tighten the installation adjustment component 1.

[0063] Step S4 also includes the following steps:

[0064] S41, the intelligent controller 7 controls the lubricating oil extraction drive module to work, so that the external oil supply equipment works. The oil supply equipment transmits lubricating oil through the oil pipe 25 to the lubricating oil storage chamber 24. After the oil supply equipment has worked for a preset time, it automatically stops running. The lubricating oil in the lubricating oil storage chamber 24 flows out through the flow hole 26 and seeps into the anti-scratch pad 27 to lubricate the outside of the drive shaft and the connection.

[0065] S42, the filter screen 45 filters and removes oil residue and impurities from the lubricating oil. The removed oil residue and impurities accumulate in the slag collection section 44. The flow rate detector 29 detects the flow rate of the lubricating oil flowing through the flow hole 26. When the flow rate value is less than the preset range, it indicates that the oil residue and impurities have caused the filter screen 45 to be blocked. The intelligent controller 7 alerts the background monitoring personnel through the warning module, reminding the staff to clean the filter screen 45.

[0066] Working principle: When using this device, firstly, the two sets of rotary positioning devices are symmetrically installed below the drive box of the stacker's traveling rotary mechanism using mounting bolts 9. The contact sensor 10 contacts the bottom of the drive box and operates. After the stacker's traveling rotary mechanism completes its operation, the signal is transmitted to the intelligent controller 7 through the traveling rotary mechanism output module. The intelligent controller 7 controls the lifting drive component 2 to operate, and the cylinder 18 moves to push the connecting plate 19, causing the connecting rod 20 to drive the tire drive shaft positioning component 3 to adjust its position in the vertical direction. As the traveling rotary positioning device is used for longer periods, a gap will be generated between the mounting plate 8 and the bottom of the drive box. When the gap reaches the maximum preset range, the contact sensor 10 will... The signal is transmitted to the intelligent controller 7. The intelligent controller 7 alerts the background monitoring personnel via the warning module, reminding them to tighten the installation adjustment component 1. After the height adjustment of the tire drive shaft positioning component 3 is completed, the intelligent controller 7 controls the adjustment motor 13 to run, driving the threaded rod 12 to rotate. The rotation of the threaded rod 12 causes the adjustment plate 14 to move inside the sliding groove 15, driving the lifting drive component 2 and the tire drive shaft positioning component 3 to move horizontally. The limit rod 17 ensures the stability of the adjustment plate 14 during movement. The distance sensor 36 detects the distance between the tire drive shaft positioning component 3 and the drive shaft of the stacker's traveling and rotating mechanism. When the anti-scratch pad 27 of the positioning frame 21 is detected to be close to the drive shaft, the sensor detects the distance between the tire drive shaft positioning component 3 and the drive shaft of the stacker's traveling and rotating mechanism. When the outer side of the shaft contacts the drive shaft, the distance sensor 36 transmits a signal to the intelligent controller 7. The intelligent controller 7 controls the adjusting motor 13 to stop working. The intelligent controller 7 controls the electric telescopic rod 32 to push the auxiliary positioning arc plate 37, causing it to slide and move downward inside the limiting groove 33. After the auxiliary positioning arc plate 37 moves into place, the locking motor 39 runs, driving the adjusting screw 40 to rotate and causing the limiting circular plate to screw in towards the drive shaft, clamping the outer side of the drive shaft. When the contact sensing coil 43 contacts the outer side of the drive shaft, the contact sensing coil 43 transmits a signal to the intelligent controller 7. The intelligent controller 7 controls the locking motor 39 to stop working. The intelligent controller 7 controls the lubricating oil extraction drive module to operate. When the external oil supply equipment is activated, it transmits lubricating oil through the oil pipe 25 to the lubricating oil storage chamber 24. After the oil supply equipment has been operating for a preset time, it automatically stops. The lubricating oil in the lubricating oil storage chamber 24 flows out through the flow hole 26 and seeps into the anti-scratch pad 27 to lubricate the outside of the drive shaft and the connection. The filter screen 45 filters and removes oil residue and impurities in the lubricating oil. The removed oil residue and impurities accumulate in the slag collection section 44. The flow rate detector 29 detects the flow rate of the lubricating oil flowing through the flow hole 26. When the flow rate is less than the preset range, it indicates that oil residue and impurities have caused the filter screen 45 to be blocked. The intelligent controller 7 alerts the background monitoring personnel through the warning module, reminding the staff to clean the filter screen 45.
