Description

Technical Field

[0001] The invention relates to the technical field of transport devices, in particular to an unloading mechanism of an indoor equipment transport forklift and a transport forklift. Background Art

[0002] Indoor equipment rooms such as panel cabinets and electrical boxes in indoor substations are important components of the power system. As a power transmission hub connecting substations and power-consuming equipment, it plays a key role in industrial fields such as electricity, petrochemicals, and steel.

[0003] Most of the existing indoor equipment in distribution stations is transported to the substation by forklifts. The structure of the forklifts is mostly as described in the text of the Chinese patent number CN215249370U, which is called a distribution cabinet transport forklift with an anti-dumping structure. It is mainly composed of a forklift body and a forklift shovel that carries objects and can do lifting and lowering movements. When transporting electrical equipment, the forklift shovel supports the electrical equipment, and the forklift body moves to transport the electrical equipment to the substation. Since the existing indoor equipment such as screen cabinets not only has a large gravity but also mostly has no wheels, when the forklift is transported to the designated location, due to the large gravity of the indoor equipment, there is a large friction between the forklift shovel and the indoor equipment, and it often requires the cooperation of multiple people to push or pull the indoor equipment and the forklift shovel to separate. Obviously, there is a problem of insufficient unloading convenience, which needs to be solved urgently. Summary of the invention

[0004] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides an indoor equipment transport forklift unloading mechanism and a transport forklift, which not only eliminates the need for multiple people to cooperate in unloading indoor equipment, but also improves the convenience of unloading indoor equipment.

[0005] To achieve the above object, the present invention provides the following technical solutions:

The inclined seat has a storage state of sliding inward to the receiving groove and an expanded state of sliding outward to form a smooth connection with the horizontal seat. The unloading bearing assembly also includes a positioning pin for locking the expanded state.

[0009] As a further solution of the present invention: the horizontal seat is provided with an open groove arranged along the sliding direction of the tilting seat, the tilting seat is fixed with a slide bar that forms a sliding fit with the open groove, the slide bar is provided with a socket, and the end of the positioning pin is provided with an insertion rod that can form a plug-in fit with the socket, so that when the positioning pin is plug-in fit with the socket, the positioning pin constitutes a driving handle that drives the slide bar to slide in the open groove.

[0010] A transport forklift, which applies the indoor equipment transport forklift unloading mechanism, includes a vehicle body and a power mechanism for driving the forklift shovel to perform lifting movements; the power mechanism includes a column installed on the vehicle body, a lifting frame is slidably connected to the column, the forklift shovel is fixed to the bottom of the lifting frame through a vertically distributed support seat, and a first hydraulic cylinder for driving the lifting frame to perform lifting movements is fixed on the column.

[0011] As a further solution of the present invention: the lower part of the column is rotatably connected to the vehicle body through a horizontal rotating shaft, the horizontal rotating shaft is perpendicular to the cargo unloading direction, and a second hydraulic cylinder for driving the column to rotate around the horizontal rotating shaft is installed on the vehicle body.

[0012] As a further solution of the present invention: an anti-roll mechanism is arranged on the upper part of the column, and the anti-roll mechanism includes two roll baffles distributed parallel to the cargo unloading direction, and a accommodating interval for accommodating the cargo is provided between the two roll baffles, and the width of the accommodating interval is adjustable.

[0013] As a further solution of the present invention: the anti-roll mechanism also includes a sliding rail fixed on the column, the sliding rail is arranged along the width direction of the accommodating interval, the roll baffle is slidably fitted on the sliding rail, and the sliding rail is rotatably fitted with a double-headed screw, and connecting components are installed on the two roll baffles, and the two connecting components respectively form a second screw slider drive mechanism with the rod body at both ends of the double-headed screw.

[0014] As a further solution of the present invention: the roll baffle is slidably engaged on the slide rail through a sliding seat, and the roll baffle can be rotatably engaged on the slide rail around a horizontal axis distributed perpendicular to the cargo unloading direction, so that the roll baffle can be rotated and adjusted to a horizontal working state or a vertical release state.

[0015] As a further solution of the present invention: an L-shaped connecting seat is fixed at one end of the roll baffle adjacent to the horizontal axis, and the connecting assembly includes threaded barrels respectively screwed on the rods at both ends of the double-headed screw, and the threaded barrels are hingedly connected to the cantilever end of the L-shaped connecting seat through a hinge rod, and the direction of the hinge axis connecting the hinge rod, the threaded barrel and the L-shaped connecting seat is parallel to the double-headed screw; the double-headed screw is detachably mounted on the column through a positioning mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A discharge mechanism is integrated on the forklift shovel, and the discharge bearing member of the discharge mechanism forms a sliding fit with the discharge mechanism in the vertical direction. When transporting goods, the horizontal platform of the discharge bearing member slides to the transporting state below the forklift shovel bearing surface, and the forklift shovel carries the goods at this time; when unloading goods, the horizontal platform of the discharge bearing member slides to the unloading state above the forklift shovel bearing surface, and the discharge bearing member carries the goods. When unloading goods, the rollers on the discharge bearing member reduce the resistance of the goods to slide, and the goods slide in turn on the horizontal platform and the downward inclined platform smoothly connected to the horizontal platform, so as to achieve low-resistance and smooth unloading of goods.

[0018] 2. A sliding fit is formed between the unloading bearing member and the forklift shovel through protrusions and grooves. When the forklift shovel rises, the unloading bearing member slides downward under the action of gravity to form a cargo transportation state; and when the forklift shovel descends, the unloading bearing member moves upward relative to the forklift shovel under the obstruction of the ground to form an unloading state of the unloading bearing assembly, thereby eliminating the need for an additional power source to drive the unloading bearing member, thereby ensuring stable operation of the device and reducing the cost of the device.

[0019] 3. The unloading bearing member adopts the form of horizontal sliding cooperation and storage of the horizontal seat and the inclined seat, which can reduce the space occupied by the unloading bearing member during transportation.

[0020] 4. The horizontal seat is provided with an open groove arranged along the sliding direction of the tilting seat, a slide bar that forms a sliding match with the open groove is fixed on the tilting seat, a plug hole is provided on the slide bar, and a plug rod that can form a plug-in match with the plug hole is provided at the end of the positioning pin. When the positioning pin is plugged with the plug hole, the positioning pin constitutes a driving handle that drives the slide bar to slide in the open groove, so as to drive the tilting seat to slide out of the receiving groove.

[0021] 5. The column on which the forklift shovel is installed can be driven by the second hydraulic cylinder to adjust the tilt angle. During transportation, when the height of the cargo in the transported panel cabinet is greater than the door height of the secondary equipment room and the relay protection room in the substation, the column and the forklift shovel are driven to tilt and the overall height of the cargo is lowered to achieve stable passage through the low-height channel.

[0022] 6. Two roll baffles are provided to prevent the cargo from tipping over on both sides. The spacing between the two roll baffles is adjustable to prevent cargo of different sizes from tipping over. In addition, the roll baffle can be rotated and adjusted around a horizontal axis perpendicular to the cargo unloading direction, freeing up space above the forklift shovel so that the cargo can be hoisted on the forklift shovel without obstruction.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0035] The specific structure of the present invention refers to Figure 1-8 As shown, its main structure includes a vehicle body 10, a forklift shovel 44 mounted on the vehicle body 10, a power mechanism 40 for driving the forklift shovel 44 to rise and fall, a discharge mechanism 30 for assisting the forklift shovel 44 in discharging goods, and an anti-tilt mechanism 20 for preventing the goods from tipping over during the unloading process. Each component is described in detail below.

[0036] 1. Power mechanism 40

[0037] like Figure 4As shown, the power mechanism 40 includes a column 41 installed on the vehicle body 10, and a lifting frame 46 is slidably connected to the column 41. The forklift shovel 44 is fixed to the bottom of the lifting frame 46 through a vertically distributed support seat 43, which ensures the stability of the lifting and sliding of the forklift shovel 44. In addition, a first hydraulic cylinder 45 is installed on the column 41 to drive the lifting frame 46 to perform lifting and lowering movements. Further, a crossbar 411 is fixed on the upper part of the column 41, and a sprocket 49 is installed on the lifting frame 46. A chain 48 is meshed on the sprocket 49, and the two ends of the chain 48 are respectively fixed to the crossbar 411 and the support seat 43. The cooperation of the chain 48 and the sprocket 49 keeps the lifting frame 46 stable during lifting and lowering, and the lifting frame 46 is supported by the tension of the chain 48 to prevent the lifting frame 46 from shaking and sagging during operation.

[0038] On the basis of the above, if Figure 4 As shown, the lower part of the column 41 is rotatably connected to the vehicle body 10 through a horizontal rotating shaft, and the horizontal rotating shaft is perpendicular to the cargo unloading direction. A second hydraulic cylinder 42 for driving the column 41 to rotate around the horizontal rotating shaft is installed on the vehicle body 10. The second hydraulic cylinder 42 can be used to drive the column 41 and the forklift shovel 44 to tilt as a whole through the telescopic movement of the second hydraulic cylinder 42. When the height of the transported panel cabinet cargo is greater than the door height of the secondary equipment room or relay protection room in the substation, the column 41 and the forklift shovel 44 are tilted as a whole to reduce the overall height of the cargo, so that the transport forklift can stably pass through the door or material passage with insufficient height space.

[0039] On the basis of the above, if Figure 4 and Figure 5 As shown, an anti-roll mechanism 47 is provided on the upper part of the column 41, and the anti-roll mechanism 47 includes two roll baffles 472 distributed parallel to the cargo unloading direction, and a storage space for accommodating cargo is provided between the two roll baffles 472, so as to prevent the cargo from rolling during transportation or unloading. In addition, the width of the storage space is adjustable to accommodate cargo of different widths.

[0040] Specifically, Figure 5 As shown, the anti-roll mechanism 47 also includes a slide rail 471 fixed on the column 41, the slide rail 471 is arranged along the width direction of the accommodation interval, the roll baffle 472 is slidably matched on the slide rail 471, and a double-headed screw 475 is rotatably matched on the slide rail 471. A connecting component is installed on both roll baffles 472, and the two connecting components form a second screw slider driving mechanism with the rod body at both ends of the double-headed screw 475. By rotating the double-headed screw 475, the two connecting components can be driven to drive the two roll baffles 472 to move closer to or away from each other, so as to adjust the accommodation interval between the two roll baffles 472. In addition, a first buffer pad 4721 is fixed to the inner side wall of the roll baffle 472 to achieve collision buffering of the goods.

[0041] Further, such as Figure 5 As shown, the roll baffle 472 is slidably engaged on the slide rail 471 through the slide seat 473, and the roll baffle 472 can be rotatably engaged on the slide rail 471 around a horizontal axis parallel to the cargo unloading direction, so that the roll baffle 472 can be rotated and adjusted to a horizontal working state or a vertical release state. Figure 6 As shown, when the roll guard plate 472 is in the vertical released state, it can vacate the space above the forklift shovel 44 so that the cargo can be lifted on the forklift shovel 44 without obstruction.

[0042] Specifically, Figure 5 and Figure 6 As shown, the horizontal axis is arranged at one end of the roll baffle 472, and preferably the horizontal axis is arranged on the side directly above the forklift shovel 44, so that the roll baffle 472 is well misaligned with the space directly above the forklift shovel 44 after being rotated to vertical. In addition, an L-shaped connection seat 4722 is fixed to one end of the roll baffle 472 adjacent to the horizontal axis, and the connection assembly includes a threaded cylinder 4741 respectively screwed on the rod body at both ends of the stud screw 475, and the threaded cylinder 4741 is hingedly connected to the cantilever end of the L-shaped connection seat 4722 through the hinge rod 474, and the hinge axis direction of the hinge rod 474 connecting the threaded cylinder 4741 and the L-shaped connection seat 4722 is parallel to the stud screw 475; the stud screw 475 is detachably installed with the column 41 through the positioning mechanism 476. When rotating the roll baffle 472, first release the installation fixation between the double-headed screw 475 and the column through the positioning mechanism 476. At this time, use the double-headed screw 475 as a driving handle, pull down the double-headed screw 475, and drive the hinge rod 474 to generate a flipping force on the L-shaped connecting seat 4722. The lever principle is used to drive the roll baffle 472 to rotate to a vertical flipping action, and the rotation adjustment of the roll baffle 472 and the adjustment of the accommodating interval are integrated, which has the advantages of convenient adjustment and labor saving.

[0043] Specifically, Figure 5 As shown, the positioning mechanism 476 for disassembling and assembling the stud screw 475 includes an L-shaped plate 4763 fixed to the column 41 or the slide rail 471, and the horizontal end of the L-shaped plate 4763 is detachably mounted with a limit plate 4761 through a connecting bolt 4762. The limit plate 4761 is a bent structure that bends toward the vertical section of the L-shaped plate 4763. The inner wall of the limit plate 4761 and the inner wall of the L-shaped plate 4763 enclose a positioning cavity that prevents the stud screw 475 from moving radially, thereby realizing the detachable installation between the stud screw 475 and the column 41 or the slide rail 471. In actual implementation, the positioning mechanism 476 can also be a fixed sleeve sleeved on the screw rod of the stud screw 475, and the fixed sleeve can be detachably mounted with the column 41 or the slide rail 471 through a locking bolt.

[0044] 2. Discharging mechanism 30

[0045] like Figure 1-3 As shown, the unloading mechanism 30 is arranged on the forklift shovel 44. The unloading mechanism 30 includes an unloading bearing member that can form a vertical sliding fit with the forklift shovel 44, and a roller 33 is installed on the upper surface of the unloading bearing member to reduce the friction resistance of the goods sliding on the unloading bearing member, thereby improving the convenience of the unloading operation.

[0046] Specifically, Figure 1 As shown, the upper surface of the unloading carrier includes a horizontal platform and a downward-inclined platform that can be smoothly connected to the horizontal platform. The goods slide from the horizontal platform to the downward-inclined platform and then to the ground, ensuring the smoothness of the goods sliding from the unloading carrier to the ground. Figure 2 As shown, in the cargo transport state, the horizontal platform of the unloading bearing member is located below the bearing surface of the forklift shovel 44, and the forklift shovel 44 serves as a supporting bearing structure for the cargo. Figure 1 As shown, in the unloading state, the horizontal platform of the unloading carrier is located below the bearing surface of the forklift shovel 44, and the unloading carrier serves as a supporting structure for the goods. At this time, the unloading carrier can be used to conveniently unload the goods.

[0047] On the basis of the above, if Figure 2 and Figure 3 As shown, the unloading carrier forms a sliding fit with the groove 441 on the forklift shovel 44 through the protrusions 311 on both sides. When the forklift shovel 44 rises, the protrusion 311 on the unloading carrier sinks to the lower groove end of the groove 441 due to gravity, and forms the cargo transporting state of the unloading carrier; when the forklift shovel 44 descends, the unloading carrier moves upward relative to the forklift shovel 44 under the obstruction of the ground, so as to form the unloading state of the unloading carrier assembly, thereby eliminating the need for an additional power source to drive the unloading carrier, thereby ensuring stable operation of the device and reducing the cost of the device.

[0048] Further, such as Figure 2 and Figure 3 As shown, the unloading bearing member includes a horizontal seat 31 and an inclined seat 32, and the upper surfaces of the horizontal seat 31 and the inclined seat 32 respectively form a horizontal platform and a downward inclined platform. Among them, a receiving groove 314 is provided at the bottom of the horizontal seat 31, and a horizontal sliding fit is formed between the inclined seat 32 and the receiving groove 314; the inclined seat 32 has a storage state in which it slides inwardly into the receiving groove 314 and a deployment state in which it slides outwardly to form a smooth connection with the horizontal seat 31, and the unloading bearing assembly also includes a positioning pin 34 for locking the deployment state. Through the storage structure that can slide and cooperate with each other between the horizontal seat 31 and the inclined seat 32, the space occupied by the unloading bearing member during the handling process is effectively reduced.

[0049] Specifically, Figure 3As shown, the horizontal seat 31 is provided with an open groove 312 arranged along the sliding direction of the tilting seat 32, and a slide bar 321 is fixed on the tilting seat 32 to form a sliding fit with the open groove 312. The sliding fit between the slide bar 321 and the open groove 312 can position the tilting seat 32 at the extreme positions in the storage state and the unfolded state. One end of the positioning pin 34 is smooth, and the other end is provided with an external thread 341. When the tilting seat 32 is in the unfolded state, the smooth end of the positioning pin 34 is inserted into the thread groove 442 of the forklift shovel 44 and the positioning hole 313 on the horizontal seat 31 in sequence, and finally the external thread 341 is screwed with the thread groove 442 to fix the position of the positioning pin 34. At this time, the outer wall of the positioning pin 34 abuts against the inner wall of the tilting seat 32 to achieve locking of the tilting seat 32 in the unfolded state. Furthermore, a socket 3211 is provided on the slide bar 321, and an insert rod 342 which can be plugged into the socket 3211 is provided at the end of the positioning pin 34, so that when the positioning pin 34 is plugged into the socket 3211, the positioning pin 34 forms a driving handle for driving the slide bar 321 to slide in the opening groove 312, and the tilting seat 32 can be conveniently driven to slide outward through the driving handle.

[0050] Furthermore, if Figure 2 and Figure 3 As shown, in order to facilitate the storage of the positioning pin 34, a storage groove 443 for storing the positioning pin 34 is provided on the forklift shovel 44. In addition, a movable baffle 444 is provided at the notch of the storage groove 443. In a specific implementation, the movable baffle 444 can slide at the notch, thereby locking the positioning pin 34 in the storage groove 443 or unlocking the positioning pin 34. In a specific implementation, the movable baffle 444 can adopt a spring-driven sliding form to ensure that the movable baffle 444 does not slide freely when locking the positioning pin 34.

[0051] 3. Anti-tilt mechanism 20

[0052] like Figure 1 , Figure 7 and Figure 8 As shown, the anti-tilt mechanism 20 is also provided on the forklift shovel 44, and is connected to the forklift shovel 44 to ensure that the anti-tilt mechanism 20 can move synchronously with the forklift shovel 44 during the lifting process of the forklift shovel 44, thereby ensuring a good anti-tilt effect on the cargo. The anti-tilt mechanism 20 includes a strap 22 for binding cargo and an adjustment mechanism that can adjust the strap 22 as a whole along the cargo unloading direction. While fixing the cargo, the position of the strap 22 can be adjusted as the cargo moves, thereby achieving stable fixation of the cargo during the unloading process.

[0053] Specifically, Figure 7 and Figure 8As shown, the anti-tilt mechanism 20 includes a damping telescopic rod 21 hinged to the forklift shovel 44 at the bottom through a damping horizontal rotating shaft 211, and the axial direction of the damping horizontal rotating shaft 211 is perpendicular to the cargo unloading direction, and the strap 22 is fixed to the top telescopic end of the damping telescopic rod 21. The anti-tilt mechanism 20 also includes a stroke adjustment component that can adjust the rotation angle stroke of the damping telescopic rod 21. The damping telescopic rod 21 and the stroke adjustment component together constitute an adjustment mechanism. When in use, especially when the cargo slides onto the tilting seat 32, after the rotation angle stroke of the damping telescopic rod 21 is increased in cooperation with the stroke adjustment mechanism, the damping telescopic rod 21 and the damping horizontal rotating shaft 21 are used to achieve a damped slow slide of the cargo, thereby preventing the cargo from being damaged by impact during the unloading process.

[0054] On the basis of the above, if Figure 7 As shown, the stroke adjustment member includes an adjustment screw 24 that rotates with the vehicle body 10 and a moving seat 23 that forms a first screw slider driving mechanism with the adjustment screw 24. The outer end of the moving seat 23 is provided with a stroke cavity that passes through from top to bottom. A section of the rod body of the damping telescopic rod 21 is located in the stroke cavity, and the cavity wall of the stroke cavity constrains the rotation angle of the damping telescopic rod 21. During adjustment, by rotating the adjustment screw 24, the moving seat 23 is driven to slide along the cargo unloading direction, so that the cavity wall position of the stroke cavity of the moving seat 23 changes, thereby changing the angle constraint of the damping telescopic rod 21, and realizing the adjustment of the rotation stroke of the damping telescopic rod 21. In actual implementation, in order to facilitate the rotation of the adjustment screw 24, a turntable 241 is set at the end of the adjustment screw 24.

[0055] Further, such as Figure 7 and Figure 8 As shown, the outer end of the movable seat 23 is hinged to two hinged plates 25 through a hinge seat, and the axis of the hinge seat is parallel to the damping horizontal rotation axis 211. The outer ends of the two hinged plates 25 are fixed with a detachable abutment plate 26, and the two hinged plates 25, the detachable abutment plate 26 and the movable seat 23 together enclose a travel cavity. By connecting the detachable abutment plate 26 with the hinged plate 25, after the damping telescopic rod 21 rotates to any angle, the detachable abutment plate 26 can rotate with the hinged plate 25 to achieve a large-area fit between the detachable abutment plate 26 and the damping telescopic rod 21, thereby avoiding damage to the detachable abutment plate 26 or the damping telescopic rod 21 caused by uneven force. In addition, the detachable structure of the detachable abutment plate 26 can achieve the self-ascent of the forklift shovel 44 by disassembling the detachable abutment plate 26 when the detachable abutment plate 26 hinders the forklift shovel 44 from rising.

[0056] In actual implementation, Figure 8 As shown, a third buffer pad 261 is fixed to the outer side of the detachable abutment plate 26, and a second buffer pad 212 is fixed to the side of the damping telescopic rod 21 adjacent to the cargo to achieve collision buffering for the cargo.

[0057] In addition, if Figure 1 As shown, the vehicle body 10 structure in the present application also includes a truck bucket 11, which can be used for storing goods and placing counterweights to ensure balanced force at both ends of the vehicle body 10. The vehicle body 10 also includes a standing platform 12, and a handlebar 13 for controlling the shape and direction of the vehicle body 10 is provided on the standing platform 12. Specifically, the standing platform 12 is located at one end of the forklift shovel 44 on the vehicle body 10, which further facilitates maintaining balanced force at both ends of the vehicle body 10.

[0058] It is worth mentioning that in order to ensure the stable operation of the transport forklift, the present application also provides a transport method for the operation of the transport forklift, and makes adaptive changes to the structure of the vehicle body 10. Specifically, the running wheels of the vehicle body 10 are all configured as power wheels, and the power wheels can be driven by the lifting frame on the vehicle body 10 to perform lifting movements (not shown in the figure). The lifting frame can adopt the scissors-type lifting mechanism or the gear rack linear lifting mechanism in the prior art.

[0059] like Fig. 9 As shown, the handling method comprises the following steps:

[0060] S1. Obtain the pressure values ​​borne by all power wheels in the handling equipment in real time;

[0061] S2, input the pressure value data into the central processing unit, and obtain the driving signal of each power wheel once every time period, and control each power wheel to perform the driving action according to the corresponding driving signal;

[0062] S3. The central processor controls the lifting frame on the power wheel to perform lifting actions according to the predicted strategy based on the pressure value obtained in real time, so that the pressure value of each power wheel is equal to the set threshold.

[0063] By obtaining the pressure values ​​of all the power wheels in the handling equipment, the driving signals of different power wheels are obtained to achieve the optimal distribution of power and ensure the smooth operation of the handling equipment. In addition, according to the pressure value, the height of the power wheel is also adjusted to reduce the tilt of the handling equipment while ensuring the load balance between the power wheels.

[0064] In actual implementation, the pressure value of the power wheel can be directly obtained by installing a pressure sensor between the power wheel and the vehicle body 10.

[0065] Specifically, the process of the central processing unit obtaining the driving signal includes:

[0066] Obtaining compensation signal B of each power wheel;

[0067]

[0068] Where, t represents the tth time period;

[0069] i represents the i-th power wheel;

[0070] B i (t) represents the compensation signal of the i-th power wheel at the t-th time period;

[0071] P i (t) represents the pressure value of the i-th power wheel at the t-th time period;

[0072] P * (t) represents the mean pressure value of all power wheels at the tth time period;

[0073] Obtaining a driving signal A of each power wheel;

[0074] A i (t) = T i +B i (t)

[0075] Among them, A i (t) represents the driving signal of the i-th power wheel at the t-th time period;

[0076] T i Represents the duty cycle modulation signal in the original drive signal of the i-th power wheel.

[0077] The vehicle body is provided with a power module for driving the power wheels to rotate. The power module includes a motor, and the driving signal adopts a PWM signal.

[0078] When the duty cycle modulation signal of the drive signal of the corresponding power wheel is generated, a compensation value is generated based on the pressure value at the corresponding power wheel and the average of the pressure values ​​at all the corresponding power wheels.

[0079] The central processing unit generates a compensation value output by the corresponding power wheel and a duty cycle modulation signal associated with the pressure signal at the corresponding power wheel, thereby being able to better control different power wheels and ensure smooth operation of the handling equipment.

[0080] Based on the above, the prediction strategies include:

[0081] Compare the pressure value of each power wheel obtained in real time with the threshold value preset in step S3;

[0082] The central processor controls the lifting frame of the power wheel with a pressure value less than the threshold to rise, and controls the lifting frame of the power wheel with a pressure value less than the threshold to descend, until the pressure value of the power wheel is equal to the threshold, thereby ensuring load balance between the power wheels. This load balancing operation mode can also effectively reduce the problem of uneven wear of the power wheels caused by uneven load.

[0083] Of course, in actual implementation, this transport method can be used not only for the transport forklift in the present application, but also for the collaborative transport of multiple transport tanks in the prior art, and the walking wheels of each transport tank are also set as power wheels that can be raised and lowered.

[0084] Of course, it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
