Description

Technical Field

[0001] This invention belongs to the field of hoisting equipment technology, specifically a trackless heavy-duty field hoisting device. Background Technology

[0002] Trackless heavy-duty field lifting equipment includes truck cranes, which are cranes mounted on ordinary or specially designed truck chassis, with separate driver's cab and crane operator's cab. The advantages of this type of crane are good mobility and rapid transfer. The chassis performance of the truck crane is equivalent to that of a truck with the same total weight, meeting the technical requirements of highway vehicles, and therefore can travel on various types of roads and in the field. This type of crane is generally equipped with two operator's cabs, one for the upper cab and one for the lower cab, and outriggers need to be extended to maintain stability during operation.

[0003] However, during hoisting, if a heavy object is being hoisted from a height, the wind can push the object and generate a horizontal force that exceeds the crane's stability limit. Furthermore, if the object accidentally collides with other objects during hoisting, generating a reaction force, it can cause the boom to swing and the crane to become unbalanced, or even overturn. In addition, during hoisting operations, steel cables are frequently exposed to dust, mud, water, oil, and other impurities, and are subjected to tensile, bending, friction, and impact loads over a long period of time, making them prone to wear, broken wires, corrosion, and deformation. If a small number of broken wires or localized corrosion are not dealt with in time, they will rapidly expand under continuous stress, eventually causing the entire steel cable to suddenly break. This can lead to the truck crane losing its load during hoisting and generating a sudden reaction force, increasing the risk of the truck crane overturning. Summary of the Invention

[0015] The beneficial effects of this invention are as follows: 1. The trackless heavy-duty field hoisting device of the present invention involves a steel cable that sways after suspending a heavy object. If the sway amplitude is too large, the weight of the object plus the inertial force generated by the sway can easily cause safety hazards. The sway amplitude range during hoisting is not accurately determined by visual estimation, making it inconvenient for personnel to control and mitigate the sway of the steel cable. Therefore, when the steel cable sways, it drives the detection frame to sway, and the detection frame presses the telescopic rod into the telescopic tube. The sensor detects and calculates the sway amplitude through displacement data, providing personnel with accurate data on the sway amplitude of the steel cable. This facilitates subsequent operations, improves the safety of the hoisting process, and enhances the ease of use of the hoisting device.

[0016] 2. The trackless heavy-duty field hoisting device of the present invention uses a cleaning tank to spray cleaning fluid onto the steel cable through cleaning nozzles. Since the cleaning nozzles are located on the detection frame, the cleaning nozzles, the detection frame, and the steel cable swing together, ensuring that the cleaning nozzles can continuously spray cleaning fluid onto the steel cable, shortening the cleaning time and improving the cleaning efficiency. Furthermore, when the cleaning nozzles swing together, they can spray cleaning fluid onto the steel cable at a fixed distance and with a fixed force, improving the flushing and impurity removal effect. This avoids the problem of inconsistent swinging of the steel cable and the cleaning nozzles, which would cause changes in distance and result in inconsistent spraying force, affecting the flushing effect.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: To effectively solve the above problems, see the attached diagram in the instruction manual. Figures 1-11 As shown, a trackless heavy-duty field lifting device includes a crane 1, a lifting platform 11, a lifting boom 12, and a lifting mechanism; it also includes: A detection box 13 is installed at one end of the lifting arm 12. A telescopic tube 14 is hinged inside the detection box 13 via a torsion spring. A telescopic rod 15 is slidably connected inside the telescopic tube 14. A spring is provided between one end of the telescopic tube 14 and one end of the telescopic rod 15. A detection frame 16 is provided at the other end of the telescopic rod 15. The steel cable in the lifting mechanism passes through the detection box 13 and the detection frame 16 from top to bottom. A sensor is provided between the telescopic rod 15 and the telescopic tube 14. A detection instrument 17 is provided on the inner wall of the detection box 13 facing the steel cable. A cleaning box 18 is installed on the lifting platform 11. A cleaning nozzle 19 is provided on the side wall of one side of the detection frame 16. Cleaning ring 2, the cleaning ring 2 is sleeved on the bottom of the detection frame 16, and the inner ring of the cleaning ring 2 is provided with a cleaning brush 21. A lifting rod 22 is slidably connected to the outer wall of the detection frame 16, and the bottom of the lifting rod 22 rotates on the cleaning ring 2. A motor 23 is installed at the bottom of the lifting rod 22 to drive the cleaning ring 2 to rotate. The top of the lifting rod 22 is connected to the lifting device 24 installed on the outer wall of the detection frame 16. Sensors, such as displacement sensors, are used to measure the displacement of the detection frame 16 caused by the swinging of the steel cable. The detection frame 16 then causes the telescopic rod 15 to extend into the telescopic tube 14. The sensor detects the displacement of the telescopic rod 15 within the telescopic tube 14 and calculates the displacement of the detection frame 16 caused by the steel cable. This allows for the calculation of the specific swing angle during the steel cable hoisting process, providing hoisting data for the operators. The detection instrument 17 is a conventional electrical device used to detect steel cables, including surface defects and fractures. The cleaning tank 18 contains cleaning fluid, which is then delivered to the cleaning nozzle 19.

[0022] Specific workflow: During hoisting, the steel cable will swing after lifting the heavy object. If the swing amplitude is too large, the weight of the heavy object plus the inertial force generated by the swing can easily cause safety hazards. The swing amplitude range during hoisting is not accurately measured by personnel visually, making it inconvenient for personnel to control and reduce the swing of the steel cable. Therefore, when the steel cable swings, the steel cable drives the detection frame 16 to swing. The detection frame 16 presses the telescopic rod 15 into the telescopic tube 14. The sensor detects and calculates the swing amplitude through displacement data, providing personnel with accurate data on the swing amplitude of the steel cable, which facilitates subsequent operations, improves the safety of the hoisting process, and thus improves the ease of use of the hoisting device. Furthermore, when the telescopic rod 15 enters the telescopic tube 14, the telescopic rod 15 compresses the spring inside the telescopic tube 14. The reaction force generated by the spring generates swing resistance on the steel cable through the detection frame 16, which counteracts part of the motion inertia of the steel cable during swing, reduces the swing amplitude, thereby improving the stability of the steel cable and thus improving the safety of the hoisting process. Before hoisting, personnel can clean and maintain the steel cable. The cable is retracted from its extended state and raised from below. The cleaning tank 18 sprays cleaning fluid onto the cable through cleaning nozzles 19. Because the cleaning nozzles 19 are located on the detection frame 16, the nozzles 19, the detection frame 16, and the cable swing together, ensuring continuous spraying of cleaning fluid. This shortens cleaning time and improves efficiency. Furthermore, the simultaneous swinging of the nozzles allows for consistent spraying at a fixed distance and force, enhancing the flushing and impurity removal effect. This avoids inconsistent spraying force caused by misalignment between the cable and nozzles, which affects the flushing effect. Additionally, after contacting the cable, some of the cleaning fluid flows down the cable, pre-wetting the lower cable to be cleaned, ensuring thorough wetting of impurities for easy removal. Furthermore, after the steel cable below is fully wetted, the motor 23 drives the cleaning brush 21 to rotate through the cleaning ring 2. The rotating cleaning brush 21 sweeps away the impurities on the wet steel cable, improving the cleaning effect. In addition, with the flushing action of the continuously flowing cleaning liquid above, the removal of impurities on the steel cable is accelerated, improving the cleanliness of the steel cable and avoiding excessive wear caused by too many impurities in the steel cable, which could lead to steel cable breakage. While the lifting device 24 drives the cleaning ring 2 to rise and fall via the lifting rod 22, the cleaning ring 2 drives the cleaning brush 21 to rotate, causing the cleaning brush 21 to form a spiral downward or spiral upward cleaning trajectory. Since the steel cable is formed by multiple steel wires spirally wound together, the spiral cleaning trajectory of the cleaning brush 21 is the same as the spiral winding trajectory of the steel wires in the steel cable. This allows the end of the cleaning brush 21 to extend into the gaps between the intertwined steel wires and brush away the impurities stuck in the gaps, improving the cleaning effect, accelerating the removal of impurities on the steel cable, improving the cleanliness of the steel cable, avoiding excessive wear caused by too many impurities in the steel cable, and preventing the steel cable from breaking, thus improving the safety level during the hoisting process.

[0023] Example 2: Based on Embodiment 1, the top and bottom of the detection frame 16 are slidably connected to sealing plates 25, and the sealing plates 25 are symmetrically distributed with the center of the detection frame 16 as a reference. The sealing plates 25 are connected to the first electric push rod 26 installed on the detection frame 16. A clamping plate 27 is provided in the middle of the detection frame 16, and cleaning grooves 28 are evenly provided on the clamping plate 27. The inner walls of the two sides of the cleaning grooves 28 are inclined. The inner walls of the two sides of the cleaning grooves 28 are slidably connected to clamping pieces 29 by springs. The inner surface of the arc-shaped clamping pieces 29 is provided with sealing rubber. A squeezing groove 3 is provided on one side near the inside of the detection frame 16. The top and bottom of the clamping plate 29 extend into and contact the inclined surface of the squeezing groove 3. A heater is provided on the clamping plate 27. A storage box 31 and a pump 32 are provided on the lifting platform 11. The storage box 31 and the pump 32 are connected to the inside of the detection frame 16 through pipes. The storage box 31 stores lubricant. The lubricant and cleaning fluid are conventional solvents used for lubricating and cleaning steel cables. The pump 32 is a conventional air supply device. The storage box 31 is used to deliver lubricating oil into the detection frame 16. A hydraulic plate 33 is slidably connected inside the detection frame 16, and the hydraulic plate 33 is connected to a second electric push rod 34 installed on the detection frame 16. The hydraulic plate 33 is in contact with the inner wall of the detection frame 16 and the sealing plate 25 through sealing strips. The hydraulic plate 33 is provided with hydraulic holes 35, and a one-way valve and a hydraulic filter screen 36 are provided inside the hydraulic holes 35. A connecting pipe 37 is provided on the outer wall of the detection frame 16, and the two ends of the connecting pipe 37 are respectively connected to the two ends of the detection frame 16. The clamping plate 27 divides the interior of the detection frame 16 into a left space and a right space, and the left space of the detection frame 16 is further divided into a left space of the hydraulic plate 33 and a right space of the hydraulic plate 33 by the hydraulic plate 33. The detection frame 16 and the port of the connecting pipe 37 are fixedly sealed by the connecting ring 38, and the connecting pipe 37 is uniformly provided with a connecting filter 39. The bottom of the connecting pipe 37 is provided with a collection groove 4, which is located between adjacent connecting filters 39. The inner wall of the connecting pipe 37 is inclined towards the inside of the collection groove 4.

[0024] Specific workflow: After the steel cable is rinsed and brushed, the first electric actuator 26 is activated and drives the sealing plates 25 to move closer to each other. The sealing plates 25 drive the baffle to move closer to the clamping plate 27. When the two pairs of sealing plates 25 at the top and bottom of the detection frame 16 are in close contact, the inside of the detection frame 16 is sealed into a closed space. When the sealing plates 25 move closer to each other, the adjacent extrusion grooves 3 also move closer to each other. The top and bottom of the clamping piece 29 are squeezed and guided by the inclined surface of the extrusion groove 3. The clamping piece 29 changes from being squeezed and slid closer from a far away state to a close state. The clamping piece 29 contacts the surface of the steel cable through the sealing rubber. The sealing rubber adheres to the surface of the steel cable and plays a sealing role. When the sealing plates 25 are combined, the clamping plate 27, the clamping piece 29 and the sealing rubber form a partition between the two sides of the space inside the detection frame 16 with the steel cable as the boundary, sealing the left and right sides of the steel cable. Then, the cleaning nozzle 19 sprays cleaning fluid, which gathers in the space on the left side of the steel cable in the detection box 13 and the water pressure gradually increases. Since the steel cable is made of multiple steel wires wound together, there are gaps between the steel wires. The cleaning fluid is pressurized and flows laterally from the left side of the steel wires, passing through the steel cable and gathering in the space on the right side of the steel cable in the detection box 13. When the cleaning fluid passes through the steel cable, it washes away the small impurities mixed inside the steel cable. Because the small impurities and large impurities have the same contact force with the steel wire, the contact area between the small impurities and the steel wire is reduced, the pressure on the surface of the steel wire increases, resulting in increased friction force, which makes the steel wire more susceptible to wear, thereby improving the cleanliness of the steel cable and thus improving the safety during the hoisting process. Furthermore, during the cleaning process, the heater is activated to heat the cleaning fluid and the steel cable, raising the temperature of the steel cable to heat the impurities inside the cable. This softens and reduces the adhesion of oil and other impurities on the surface and inside the cable, improving the cleaning effect and thus increasing the cleaning efficiency of the steel cable. After cleaning, the pump 32 is activated to blow air onto the steel cable. The heater raises the temperature of the air flowing through the steel cable, accelerating the drying of the cable. After drying, lubricating oil is delivered to the detection frame 16 through the storage box 31. The lubricating oil flows through the inside of the steel cable, allowing the lubricating oil to fully contact the steel wires in the cable, reducing the frictional force between the steel wires, thereby reducing wear on the steel cable and preventing internal breakage, thus improving the safety of the steel cable hoisting. When the inspection frame 16 is sealed and cleaning begins, if there are too many impurities and oil stains inside the steel cable, resulting in insufficient power for the cleaning fluid to flush away these impurities, the operator activates the second electric actuator 34. The second electric actuator 34 drives the hydraulic plate 33 to move from the side wall of the inspection frame 16 closer to the clamping plate 27. The cleaning tank 18 delivers cleaning fluid to the left side of the hydraulic plate 33. When the hydraulic plate 33 returns to its original position after approaching the clamping plate 27, the hydraulic plate 33 squeezes the cleaning fluid on the left side. The cleaning fluid passes through the one-way valve in the hydraulic hole 35 and is filtered by the hydraulic filter screen 36, removing impurities such as flocculants in the cleaning fluid. This prevents impurities in the cleaning fluid from entering the inside of the steel cable when the cleaning fluid passes through it, thus affecting the cleanliness of the steel cable and improving the cleanliness of the cleaning fluid and the cleaning effect of the cleaning fluid, thereby improving the cleanliness of the steel cable. Furthermore, the inclined inner wall of the cleaning tank 28 forms a cone shape. The conical cleaning tank 28 has a wide inlet and a narrow outlet. Combined with the squeezing force of the hydraulic plate 33, it can significantly increase the flow rate and pressure of the cleaning fluid, enhancing the flushing ability on the surface and inside of the steel cable. The high-speed flowing cleaning fluid can form a stronger jet effect, which can quickly remove stubborn contaminants such as oil, rust, and debris from the surface of the steel cable. Especially for areas prone to dirt accumulation, such as grooves on the surface of the steel cable and gaps between strands of the twisted wire rope, the high-speed liquid flow can penetrate the gaps and flush out the impurities. The high-pressure cleaning fluid not only enhances surface cleaning but also provides a power basis for subsequent penetration into the interior of the steel cable. There are fiber cores or gaps between strands inside the steel cable. The high-pressure liquid flow can overcome the gap resistance and forcefully penetrate into the interior, cleaning areas that are difficult to reach by traditional methods, such as rust powder and aging grease residue inside the steel cable. As the hydraulic plate 33 moves closer to the clamping plate 27, cleaning fluid is replenished on the left side of the hydraulic plate 33, and the cleaning fluid is squeezed through the steel cable on the right side of the hydraulic plate 33. When the hydraulic plate 33 moves away from the clamping plate 27, the cleaning fluid is squeezed through the left side of the hydraulic plate 33 to complete the filtration, and the filtered cleaning fluid is stored on the right side of the hydraulic plate 33. However, since the steel cable on the crane 1 is relatively long, the continuous water supply for cleaning is large, which can easily lead to water waste, and it is inconvenient to obtain cleaning fluid in the field. Therefore, by setting up a connecting pipe 37, the cleaning fluid enters the connecting pipe 37 after passing through the steel cable. As the hydraulic plate 33 continues to work, the used cleaning fluid returns to the left side of the hydraulic plate 33 through the connecting pipe 37, and is filtered again to remove the impurities. Then, the filtered cleaning fluid is squeezed through the steel cable to realize the recycling of the cleaning fluid in the detection frame 16, which facilitates maintenance and cleaning during field hoisting and improves ease of use. By setting up connecting filters 39, the cleaning fluid is filtered multiple times by the multiple connecting filters 39 inside the connecting pipe 37 as it flows through the connecting pipe 37, removing impurities from the cleaning fluid, improving the cleanliness of the cleaning fluid, and preventing excessive impurities from entering the left side of the hydraulic plate 33 and clogging the hydraulic filter 36, thus preventing the hydraulic plate 33 from becoming blocked. By setting up a connecting ring 38, which can be replaced by a clamp or other connecting parts, the connecting pipe 37 and the detection frame 16 can be quickly disassembled and assembled through the connecting ring 38, making it convenient for workers to disassemble, clean, or replace the connecting pipe 37 after filtration, thus improving the ease of use. Furthermore, by setting up a collection tank 4, and with the inner wall of the connecting pipe 37 inclined towards the inside of the collection tank 4, impurities in the cleaning fluid are intercepted by the connecting filter 39. When cleaning is not required, the impurities fall from the connecting filter 39 onto the inner wall of the connecting pipe 37 and slide into the collection tank 4, increasing the ability of the connecting pipe 37 to collect impurities, improving the circulation capacity of the cleaning fluid, and enhancing ease of use. Additionally, the connecting filter 39 can be tilted, with its inclined surface facing the collection tank 4. This allows impurities to be intercepted on the tilted connecting filter 39 after passing through it. Because the connecting filter 39 is tilted, a small portion of the cleaning fluid is guided by the connecting filter 39 to flow along its inclined surface, flushing away the intercepted impurities and filling the collection tank 4. This achieves the self-cleaning function of the connecting filter 39, further increasing the ability of the connecting pipe 37 to collect impurities, improving the circulation capacity of the cleaning fluid, and further enhancing ease of use.

[0025] Example 3: Based on Embodiment 2, a rotating shaft 41 is rotatably connected to the outer wall of the detection frame 16. A collision rod 51 is provided on the rotating shaft 41 to contact the connecting pipe 37. A transmission rope 42 is wound on the rotating shaft 41, and one end of the transmission rope 42 is connected to the lifting rod 22. The rotating shaft 41 and the collision rod 51 are connected by rubber, so that after the collision rod 51 contacts the connecting pipe 37, it passes over the connecting pipe 37 due to the deformation of the rubber. The detection frame 16 is provided with a sliding rod 43, which is vertically slidably connected to the inclined surface of the cleaning tank 28. A swing rod 44 is hinged to the sliding rod 43 by a torsion spring. One end of the swing rod 44 contacts the steel cable, and the other end contacts the wavy part of the inner wall of the cleaning tank 28. A third electric push rod 45 is provided in the clamping plate 27, which is connected to the sliding rod 43.

[0026] Specific workflow: When the lifting rod 22 descends to wash the steel cable, the lifting rod 22 pulls the transmission rope 42, which unwinds from the rotating shaft 41, causing the rotating shaft 41 to rotate. The rotating shaft 41 then drives the collision rod 51 to rotate and collide with the connecting pipe 37. The rubber deforms and passes over the connecting pipe 37 for the next collision. The collision causes the connecting filter 39 to vibrate, shaking off the intercepted impurities into the collection tank 4, thereby increasing the ability of the connecting pipe 37 to collect impurities and improving the circulation capacity of the cleaning fluid. Furthermore, the vibration of the connecting pipe 37 can also cause the detection frame 16 and the clamping plate 27 to vibrate, causing the steel cable to vibrate slightly, which helps to loosen the impurities inside the steel cable. Combined with the washing of the cleaning fluid, this improves the cleanliness of the steel cable. Furthermore, during the cleaning and lubrication of the steel cable, the No. 3 electric actuator 45 is activated to drive the sliding rod 43 to rise and fall. During the process of the sliding rod 43 driving the swing rod 44 to rise and fall, one end of the swing rod 44 rises and falls along the wavy surface of the inner wall of the cleaning tank 28. That is, when the swing rod 44 rises and falls to the wavy recess of the cleaning tank 28, it is affected by the torsion spring and swings into this recess. The other end of the swing rod 44 moves away from the steel cable. Conversely, the swing rod 44 moves closer to and collides with the steel cable. When the cleaning fluid or lubricating oil passes through the inside of the steel cable, the vibration caused by the connecting pipe 37, combined with the slight tapping of the swing rod 44, loosens the impurities inside the steel cable, allowing the cleaning fluid or lubricating oil to pass through more smoothly, thereby improving the cleanliness and lubrication of the steel cable.

[0027] Example 4: Based on Embodiment 3, a fixed rod 46 is provided between adjacent lifting rods 22, and a collection ring 47 is evenly provided on the fixed rod 46, with the steel cable passing through the center of the collection ring 47; The inner surface of the collecting ring 47 is hinged with a combing block 48 by a torsion spring, and one side of the combing block 48 contacts the steel cable; the lifting rod 22 is equipped with a camera assembly 49; The fixed rod 46 is provided with a transmission belt 5, and the outer wall of the transmission belt 5 is connected to the cleaning ring 2, the inner wall of the transmission belt 5 is connected to the collection ring 47, and the collection ring 47 is rotatably connected to the fixed rod 46.

[0028] Specific workflow: By setting a fixing rod 46 and a collection ring 47, the cleaning fluid sprayed from the cleaning nozzle 19 can be collected by the fixing rod 46 and the collection ring 47 during the falling process, and flows to the steel cable through the holes in the collection ring 47, increasing the flow rate of the cleaning fluid flowing down the steel cable, so that the cleaning fluid can increase the flow length on the steel cable, achieving the purpose of the cleaning fluid contacting and wetting more steel cable, realizing the effect of steel cable pre-cleaning, thereby improving the cleaning efficiency of the steel cable; During the descent of the lifting boom 22, the comb block 48 descends while adhering to the surface of the steel cable, and the steel cable is in an ascending state. The comb block 48 moves and lifts up the broken steel wires on the surface of the steel cable, highlighting the location and number of broken steel wires on the steel cable, so that the camera component 49 can take pictures of these parts and complete the detection of the degree of breakage of the steel wires in the steel cable. The personnel can understand the durability and other parameters of the steel cable through this detection result and formulate maintenance plans, thereby improving the safety of hoisting. When the lifting rod 22 rises, the combing block 48 rises faster than the steel cable. The combing block 48 smooths the raised steel wires on the surface of the steel cable back to their original position, preventing them from affecting subsequent cleaning and maintenance. Furthermore, while the combing block 48 is smoothing the steel cable, the cleaning ring 2 rotates, driving the transmission belt 5 to rotate. The transmission belt 5 then drives the collecting ring 47 to rotate, causing the combing block 48 to smooth the raised steel wires in a spiral motion. This allows the steel wires to be better restored to their spiral winding state. For example, if the steel cable is made by clockwise spiral winding of steel wires, when the combing block 48 descends, it uses a counter-clockwise spiral motion to push the raised steel wires up; when the combing block 48 rises, it smooths the steel wires clockwise, reinserting them into the steel cable and preventing the raised steel wires from affecting subsequent work.
