Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment installation, and in particular to an unloading mechanism and a substation electrical equipment transporting device. Background Art

[0002] The panel cabinet is an important part of the power system. As a power transmission hub connecting the substation and the power-consuming equipment, it plays a key role in the power, petrochemical, steel and other industrial fields, and is usually placed in the indoor substation. Since the panel cabinet in the prior art is generally large in size and heavy in weight, in the process of placing the assembled panel cabinet in the equipment room, it is necessary to use the forklift and other handling tools in the prior art to move the panel cabinet.

[0003] The forklift forks in the prior art forklifts only have the function of moving up and down. After the forklift forks lift the screen cabinet to the specified height, the screen cabinet can only be moved by the forklift itself. After the screen cabinet is transported to the specified installation position by the forklift, the forklift forks are lowered to the ground, and the screen cabinet can be directly dropped to the specified installation position without the need for subsequent handling and adjustment work. However, due to the limitation of the indoor space of the equipment room, the range of movement of the forklift is limited. When the screen cabinet on the forklift forks is a certain distance away from the installation position and the forklift cannot move due to the space limitation, the forklift forks can only be lowered to the ground first, and then the screen cabinet on the forklift forks is manually moved off, and then the screen cabinet is manually transported to the specified installation position. During this process, due to the large friction between the bottom of the screen cabinet and the forklift fork, it is time-consuming and labor-intensive to rely on manual labor to move the heavy screen cabinet away. If hydraulic tools are added during this process to assist in pushing the screen cabinet, since the screen cabinet needs to be pushed down from the forklift fork, it is difficult to find an effective force point when manually operating the hydraulic tool due to the limitations of the forklift frame and the forklift's own structure, resulting in a relatively cumbersome unloading process.

[0004] Based on this, we propose a unloading mechanism to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose an unloading mechanism, which, through the setting of a pushing component, can exert a power-assisted pushing effect along a specified direction on the transported objects placed on the forks of a forklift, so that the transported objects can be easily detached from the forks of the forklift.

[0006] To solve the above problems, the present invention provides the following technical solutions:

[0007] A unloading mechanism includes an unloading mechanism body with a forklift fork, the unloading mechanism body includes a pushing assembly arranged on the body, and the pushing assembly is located above the forklift fork, the pushing assembly includes a pushing plate slidably arranged on the body, and a driving source arranged on the body and used to drive the pushing plate to move back and forth along the length direction of the forklift fork, so that the pushing plate can exert a pushing effect on the transported objects on the forklift fork.

[0008] As a further solution of the present invention: the pushing assembly also includes a sliding screw rod arranged along the length direction of the forklift fork, and a moving seat is threadedly sleeved on the sliding screw rod, two parallelly arranged push rods are slidably installed on the vehicle body along the length direction of the sliding screw rod, and one end of the two push rods is fixedly connected to the moving seat, a pushing sleeve is provided on the push plate and is plugged into the other end of the push rod, and a recovery magnetic block is provided inside the pushing sleeve and at the end of the push rod away from the moving seat, and the recovery magnetic block inside the pushing sleeve and the recovery magnetic block on the push rod attract each other.

[0009] As a further solution of the present invention: a push plate mounting plate is also provided on one side of the vehicle body where the forklift forks are installed, and a limiting through hole for cooperating with the pushing sleeve to slide is provided on the push plate mounting plate.

[0010] As a further solution of the present invention: the driving source is a driving motor, the output end of the driving motor is transmission-connected to the sliding screw, a rotating fixed seat for the sliding screw to be rotatably connected is provided on the vehicle body, and a sliding guide seat for slidingly cooperating with the push rod is provided on the vehicle body.

[0011] As a further solution of the present invention: the unloading mechanism body also includes a lifting assembly arranged on the forklift fork, the lifting assembly includes a placement rack arranged between the forklift forks, a mounting seat for fixing the placement rack is provided at the connection between the placement rack and the forklift fork, an adjusting slide groove is provided on the mounting seat, a fixed slider is provided at one end of the placement rack close to the mounting seat, and the placement rack and the mounting seat are slidably matched.

[0012] As a further solution of the present invention: a plurality of sliding rollers are provided on the upper surface of the placement rack.

[0013] As a further solution of the present invention: when the forklift fork is lowered to the lowest point, the height of the sliding roller is higher than the height of the forklift fork, and the transported object falls on the sliding roller.

[0014] As a further solution of the present invention: the unloading mechanism body also includes a brake assembly arranged on the placement rack, the brake assembly includes a brake lever hinged at the middle part of the placement rack through a rotating shaft, one end of the brake lever is provided with a friction block for increasing the friction between the placement rack and the bottom of the transported object, and the other end is provided with a cylinder for adjusting the height of the friction block.

[0015] As a further solution of the present invention: a retractable and extendable cylinder piston rod is provided in the cylinder, and the friction block is driven to move upward when the cylinder piston rod is extended, and the friction block is driven to move downward when the cylinder piston rod is retracted.

[0017] The protection mechanism includes two relatively arranged socket plates and a protection mechanism bottom plate for connecting the two socket plates. The two socket plates are respectively used to be mounted on two forklift forks, and protective plates are provided on both socket plates. The two protective plates can move towards or away from each other, so that the two protective plates have a protection state when moving towards each other and a storage state when moving away from each other.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The advantage of this unloading mechanism is that it innovatively combines the forklift fork and the pushing component. The pushing component is located above the forklift fork.

By adding a lifting component, sliding fit between the placement frame and the mounting seat, and adjusting the setting of the slide slot and the fixed slider, the lifting component can be adjusted in height as needed, thereby increasing the applicability and flexibility of the unloading mechanism;

[0023] 5. The sliding roller design on the upper surface of the rack reduces the friction between the transported objects and the rack, allowing the transported objects to move more smoothly and improving the unloading efficiency;

[0024] 6. The design of the sliding roller height ensures that when the forklift fork drops to the lowest point, the transported objects can fall on the sliding roller, avoiding direct contact with the forklift fork and protecting the transported objects;

[0025] 7. By adding a brake assembly and through the cooperation of the brake lever, friction block and cylinder, effective braking of the transported objects is achieved, improving the safety of the unloading process.

[0026] 8. Through the design of the cylinder piston rod and the telescopic movement of the cylinder piston rod, the height of the friction block can be adjusted, so that it can be adjusted according to the height and weight of the transported object, thereby improving the applicability and flexibility of the brake assembly.

[0027] 9. The advantage of the substation electrical equipment handling device in the present application is that it combines the advantages of the above-mentioned unloading mechanism and combines the design of the protective mechanism. The protective mechanism achieves effective clamping and protection of the panel cabinet through the cooperation of the socket plate, the protective mechanism bottom plate and the protective plate, thereby improving the safety and stability during the handling process.

[0047] 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.

[0048] Example 1

[0049] A substation electrical equipment handling device, such as Figure 1-Figure 6 As shown, the vehicle body 100 includes a fork frame and a door frame 110. The fork frame includes two forklift forks 1140. An unloading mechanism is provided between the fork frame and the door frame.

[0050] The unloading mechanism includes an unloading mechanism body 1100, and the unloading mechanism body 1100 includes a pushing assembly 1130 arranged above the vehicle body 100. The pushing assembly 1130 includes a sliding screw 1210 arranged along the length direction of the vehicle body 100. The upper surface of the vehicle body 100 is provided with a moving seat 1220 threadedly matched with the sliding screw 1210. The moving seat 1220 is symmetrically provided with a push rod 1230 along the length direction of the sliding screw 1210. One end of the push rod 1230 is connected to the moving seat 1220. The vehicle body 100 is equipped with a forklift fork 1140, and one side is provided with a push plate 1240 for pushing the transported objects. The push plate 1240 is provided with a pushing sleeve 1250 plugged and matched with the push rod 1230.

[0051] Through this embodiment, the sliding screw 1210 rotates to move the moving seat 1220, and the moving seat 1220 drives the push rod 1230 to move, and the push rod 1230 is inserted into the pushing sleeve 1250, and then pushes the push plate 1240 connected to the pushing sleeve 1250; the threaded cooperation between the sliding screw 1210 and the moving seat 1220 can transmit a stable mechanical pushing force, so that the transported objects can be effectively pushed during the unloading process; the threaded cooperation between the sliding screw 1210 and the moving seat 1220 drives the sliding screw 1210 to perform linear motion and cooperates with the pushing sleeve 1250 to accurately control the movement of the push plate 1240 to ensure the accuracy of unloading; the design of the pushing component 1130 can greatly reduce the time required for manual unloading, thereby improving the overall work efficiency, and at the same time, through the mechanized pushing method, it reduces the labor intensity of workers when carrying heavy objects; the design of the unloading mechanism reduces the need for workers to directly contact heavy objects, reduces the safety risks during the handling process, and increases safety.

[0052] In this embodiment, a recovery magnetic block 1260 is provided inside the pushing sleeve 1250 and at the end of the push rod 1230 away from the moving seat 1220. The recovery magnetic block 1260 inside the pushing sleeve 1250 and the recovery magnetic block 1260 on the push rod 1230 attract each other.

[0053] Through this embodiment, when the transported objects are unloaded, the sliding screw 1210 rotates in the opposite direction, driving the push rod 1230 to return to its original position, and the recovery magnetic block 1260 at the end of the push rod 1230 attracts the recovery magnetic block 1260 inside the push sleeve 1250, further driving the push plate 1240 to return to its original position; the use of the recovery magnetic block 1260 allows the push rod 1230 to automatically drive the push sleeve 1250 and the push plate 1240 back to the initial position when retracted, reducing the need for manual operation and improving the degree of automation of the operation; the automated recovery mechanism reduces the time required during unloading and handling, further improving work efficiency; the attraction between the recovery magnetic blocks 1260 can provide a stable fixing effect, ensuring that the push plate 1240 and the push sleeve 1250 will not be separated by external force during the recovery process, thereby enhancing stability.

[0054] In this embodiment, a push plate mounting plate 1270 is also provided on one side of the vehicle body 100 on which the forklift fork 1140 is installed. The push plate mounting plate 1270 is provided with a limiting through hole 1280 for cooperating with the pushing sleeve 1250 to slide.

[0055] Through this embodiment, the push plate mounting plate 1270 directly arranged on the vehicle body 100 provides a stable support for the push plate 1240 and the pushing sleeve 1250. At the same time, the design of the limiting through hole 1280 can provide precise sliding limitation for the pushing sleeve 1250, ensuring the accurate position of the push plate 1240 during the pushing and recovery process to prevent excessive movement. The limiting through hole 1280 also helps to stabilize the pushing sleeve 1250 and the push plate 1240 to prevent position displacement due to vibration or external force during the unloading process. Through the limiting function, the push plate 1240 can be prevented from exceeding the design range during operation, reducing possible collision and damage risks, and improving the overall safety of operation.

[0056] In this embodiment, a driving motor 1290 is provided at one end of the sliding screw rod 1210 away from the push plate 1240, and a rotating fixed seat 1320 connected to the upper surface of the vehicle body 100 is provided at the other end. The upper surface of the vehicle body 100 is also provided with a sliding guide seat 1310 for slidingly cooperating with the support rod 1230.

[0057] Through this embodiment, the drive motor 1290 is connected to the sliding screw 1210, driving the sliding screw 1210 to rotate forward or reverse to complete the unloading of the transported objects and the restoration of the push plate 1240; the drive motor 1290 can provide greater power than manual operation, which is suitable for pushing heavier or larger transported objects, and the motor drive reduces the dependence on manual power and reduces the labor intensity of workers; the design of the rotating fixed seat 1320 provides a stable support for the sliding screw 1210, thereby improving the stability and reliability of the entire mechanism; the design of the sliding guide seat 1310 reduces the vibration and lateral movement of the support rod 1230 during movement, ensuring smooth and well-guided movement, and the sliding guide seat 1310 also reduces the direct friction between the support rod 1230 and the vehicle body 100, thereby reducing wear and extending the service life.

[0058] In this embodiment, the unloading mechanism body 1100 also includes a lifting assembly 1150 arranged on the forklift forks 1140, and the lifting assembly 1150 includes a placement rack 1410 arranged between the forklift forks 1140, and a mounting support 1420 for fixing the placement rack 1410 is provided at the connection between the placement rack 1410 and the forklift forks 1140, and an adjusting slide groove 1430 is provided on the mounting support 1420. A fixed slider 1440 is provided at one end of the placement rack 1410 close to the mounting support 1420, and the placement rack 1410 and the mounting support 1420 are slidably matched.

[0059] Through this embodiment, the pushing component 1130 can automatically push the transported object to achieve unloading, but the friction between the bottom of the transported object and the forklift fork 1140 is relatively large, which will damage the transported object and requires the driving motor 1290 to have a large power, so a lifting component 1150 is set; by adjusting the sliding cooperation of the slide groove 1430 and the fixed slider 1440, the installation and disassembly of the lifting component 1150 can be achieved, and at the same time, the lifting component 1150 plays a limiting role. When transporting objects with smaller volume and weight, the lifting component 1150 can be disassembled, and when transporting objects with larger volume and weight, the lifting component 1150 can be installed, which increases the use range of the forklift. When the lifting component 1150 is damaged, the components can also be quickly disassembled and replaced; the use of the placement rack 1410 can prevent the transported objects from directly contacting the forklift fork 1140 during transportation, reducing potential damage to the transported objects. At the same time, the design of the placement rack 1410 can provide a stable platform for transported objects such as electrical equipment, reducing shaking during transportation.

[0060] In this embodiment, a plurality of sliding rollers 1450 are disposed on the upper surface of the placement rack 1410 .

[0061] Through this embodiment, a plurality of sliding rollers 1450 are provided on the upper surface of the placement rack 1410, which can significantly reduce the labor intensity during the unloading process. Due to the smooth rolling of the sliding rollers 1450, the operator does not need to exert too much force to move the heavy objects; the sliding rollers 1450 can reduce the damage caused by friction to the transported objects during the unloading process and protect the surface and structure of the transported objects.

[0062] In this embodiment, when the forklift fork 1140 is lowered to the lowest point, the height of the sliding roller 1450 is higher than the height of the forklift fork 1140 , and the transported object falls on the sliding roller 1450 .

[0063] Through this embodiment, when unloading the transported objects, the height of the forklift fork 1140 is slowly lowered to the lowest level. At this time, the transported objects fall directly on the sliding roller 1450. There is a smooth transition when the transported objects are transferred from the forklift fork 1140 to the sliding roller 1450, which reduces the vibration and collision of the transported objects during the transportation process. This design optimizes the transportation process and makes the loading and unloading of the transported objects more efficient and smooth.

[0064] In this embodiment, the unloading mechanism body 1100 also includes a brake assembly 1170 arranged on the placement rack 1410, and the brake assembly 1170 includes a brake lever 1510 hinged at the middle part of the placement rack 1410 through a rotating shaft, and one end of the brake lever 1510 is provided with a friction block 1520 for increasing the friction between the placement rack 1410 and the bottom of the transported object, and the other end is provided with a cylinder 1530 for adjusting the height of the friction block 1520.

[0065] Through this embodiment, the lifting component 1150 can enable the pushing component 1130 to easily push the transported object, but the transported object cannot control the speed and may fall out of control due to inertia or other factors when braking, so the brake component 1170 is provided; the design of the brake lever 1510 and the friction block 1520 increases the friction between the placement rack 1410 and the bottom of the transported object, preventing the uncontrolled fall of the transported object during the unloading process and enhancing stability; the height of the friction block 1520 can also be adjusted by the cylinder 1530, and the contact pressure between the placement rack 1410 and the transported object can be accurately controlled to adapt to transported objects of different weights and achieve precise control; the design of the brake component 1170 enables the operator to easily control the fixing and release of the transported object, improves the convenience of operation, and further improves the efficiency of the entire unloading and handling process.

[0066] In this embodiment, a retractable and extendable cylinder piston rod 1531 is provided in the cylinder 1530. When the cylinder piston rod 1531 is extended, the friction block 1520 is driven to move upward, and when the cylinder piston rod 1531 is retracted, the friction block 1520 is driven to move downward.

[0067] Through this embodiment, the contraction and extension of the cylinder piston rod 1531 can accurately control the position of the friction block 1520, ensuring that the contact pressure between the friction block 1520 and the transported object is moderate, thereby increasing the friction force while avoiding damage to the transported object; the operator does not need to manually adjust the friction block 1520, and the movement of the cylinder piston rod 1531 reduces the operating intensity and physical labor; the coordinated movement of the piston rod and the cylinder 1530 is precisely designed and can maintain reliability during long-term use.

[0068] The setting of the unloading mechanism realizes the integration of transportation and unloading, and improves the working fluency of the whole transportation process; the design of the unloading mechanism allows the transported objects to be unloaded quickly and accurately, reduces the transportation time, and improves the overall work efficiency; the integrated unloading mechanism reduces the operation risk and ensures the safety of the transportation process through various safety designs such as the limit through hole 1280, the sliding guide seat 1310, and the brake assembly 1170; the design of the unloading mechanism reduces the physical labor required by the operator, reduces the labor intensity, and can realize equipment protection at the same time, which can protect the electrical equipment of the substation from damage during the transportation process and extend the service life of the equipment.

[0069] Example 2

[0070] like Figure 1-Figure 11As shown, it is the same as Example 1, except that in this embodiment, a limiting mechanism for preventing the screen cabinet from shifting and falling off during transportation is installed on the door frame 110, and the limiting mechanism includes a main body 200, the main body 200 includes two parallel mounting seats 210, and a first limiting component 220 fixedly connected to the mounting seat 210, the first limiting component 220 includes an L-shaped first limiting plate 221 that is arranged through the mounting seat 210, and the first limiting plate 221 is used to fit with the side of the substation electrical equipment for limiting; the mounting seat 210 is provided with a first locking component 230 for fixing the distance between the two first limiting plates 221; the first limiting plate 221 is provided with a second limiting component 240 at one end away from the mounting seat 210, and the second limiting component 240 is provided with a second locking component 250 for locking the second limiting component 240 at one end away from the mounting seat 210.

[0071] By using the L-shaped first limiting plate 221 in this embodiment, when the screen cabinet is moved to the installation position, it can effectively fit the side of the screen cabinet to prevent deviation.

[0072] In this embodiment, the first locking component 230 ensures that the distance between the two first limiting plates 221 is fixed, and the second limiting component 240 further increases the limiting effect on the screen cabinet to prevent it from tilting forward. It has strong adaptability and can meet the transportation needs of screen cabinets of different sizes.

[0073] By setting the second locking component 250 in this embodiment, after the screen cabinet is fixed by the limiting mechanism, the second limiting component 240 is quickly locked.

[0074] In this embodiment, a sliding cavity 211 is provided in the mounting seat 210 , and the sliding cavity 211 is located on the upper portion of the first limiting plate 221 .

[0075] In this embodiment, the sliding cavity 211 provides a sliding space for the first locking assembly 230, which facilitates the adjustment of the spacing between the first limiting plates 221, improves the flexibility and adaptability of the limiting mechanism, and facilitates the transportation of screen cabinets of different sizes.

[0076] In this embodiment, the first locking assembly 230 includes a C-shaped connecting rod 231 connecting two mounting seats 210, and the end of the C-shaped connecting rod 231 close to the mounting seat 210 extends into the sliding cavity 211, and the end of the C-shaped connecting rod 231 close to the first limiting plate 221 is fixedly installed with an intra-cavity slider 232 for sliding up and down in the sliding cavity 211, and a first serration 233 is provided on the intra-cavity slider 232, and a second serration 2211 cooperating with the first serration 233 is provided on the end of the first limiting plate 221 close to the intra-cavity slider 232, and the upper part of the intra-cavity slider 232 is provided with a first spring 234 cooperating with the C-shaped connecting rod 231 to drive the intra-cavity slider 232 to slide up and down.

[0077] In this embodiment, the C-shaped connecting rod 231 is used to connect the two mounting seats 210 to ensure structural stability. Furthermore, the inner slide block 232 slides up and down in the sliding cavity 211, and the first sawtooth 233 at the lower end of the inner slide block 232 engages with the second sawtooth 2211 on the first limit plate 221. Pulling up the C-shaped connecting rod 231 can cancel the engagement state. At this time, according to the width of the screen cabinet, when the screen cabinet is placed on the fork, due to the shape of the sawtooth, the first limit plate 221 can be directly pushed to increase or decrease the spacing and fit the side of the screen cabinet, and the limit is quickly completed. Furthermore, the first spring 234 automatically resets the slider to improve the convenience of operation.

[0078] In this embodiment, the first locking assembly 230 further includes a pull ring 235 disposed on the upper portion of the mounting seat 210 , and the pull ring 235 is fixedly connected to the C-shaped connecting rod 231 .

[0079] By setting the pull ring 235 in this embodiment, the C-shaped connecting rod 231 can be fixed in a normal state, and the structure is firm and reliable, and the C-shaped connecting rod 231 will not fall due to the existence of the slider 232 in the cavity.

[0080] In this embodiment, the second limiting assembly 240 includes a sleeve plate 241 which is sleeved on one end of the first limiting plate 221 away from the first saw tooth 233. The end of the sleeve plate 241 away from the first limiting plate 221 is hinged to the second limiting plate 243 through a torsion spring 242. A positioning bolt 2411 is provided at the sleeve plate 241, and a limiting plate positioning hole 2212 which cooperates with the positioning bolt 2411 is provided at the first limiting plate 221.

[0081] Although the first limit plate 221 can prevent the screen cabinet from shifting when the vehicle body makes a sharp turn, the screen cabinet may tilt forward and shift or fall off during sudden braking or other situations. Therefore, the sleeve plate 241 in this embodiment connects the first limit plate 221 and the second limit plate 243 to provide an installation basis. Furthermore, the torsion spring 242 is provided so that the second limit plate 243 is located between the two first limit plates 221 and maintains the state. The two limit plates can be rotated to fit on the front or back of the screen cabinet. After cooperating with the first limit plate 221, the screen cabinet will not fall off or shift even if the vehicle body moves arbitrarily, thereby preventing the screen cabinet from tilting forward. Furthermore, the use of the positioning bolt 2411 and the positioning hole 2212 of the limit plate can adapt to screen cabinets of different lengths.

[0082] In this embodiment, the second locking assembly 250 includes a telescopic cavity 251 arranged at the end of the sleeve 241 away from the first limit plate 221, and a telescopic block 252 extending into the telescopic cavity 251 is provided on one side of the end of the sleeve 241 away from the first limit plate 221. The telescopic cavity 251 is also provided with a second spring 253 for the telescopic block 252 to extend out of the telescopic cavity 251.

[0083] By disposing the second locking assembly 250 in this embodiment, the telescopic cavity 251 provides a telescopic space for the telescopic block 252 , and the second spring 253 keeps the telescopic block 252 in an extended state.

[0084] In this embodiment, a guide surface 254 is provided at one end of the telescopic block 252 away from the telescopic cavity 251 , and the guide surface 254 is inclined.

[0085] Through the provision of the guide surface 254 in this embodiment, it is convenient for the second limiting plate 243 to push the telescopic block 252 to retract during the flipping process, thereby achieving rapid locking and improving the locking efficiency.

[0086] In this embodiment, a fixing ring 2431 vertically connected to the second limiting plate 243 is provided at one end of the second limiting plate 243 close to the torsion spring 242 . The fixing ring 2431 is used to cooperate with the telescopic clamping block 252 to fix the second limiting plate 243 .

[0087] In this embodiment, after the second limit plate 243 is flipped, the fixed snap ring 2431 will contact the guide surface 254 of the telescopic block 252, causing the telescopic block 252 to retract and compress the spring until the second limit plate 243 is completely reversed. The fixed snap ring 2431 corresponds to the telescopic block 252, and the second spring 253 is restored to match the telescopic block 252 with the fixed snap ring 2431. At this time, the second limit plate 243 completes the position locking, and there is no need to manually maintain its state continuously, and the quick locking is completed in one step.

[0088] In this embodiment, a buffer pad 212 is disposed at one end of the mounting base 210 close to the second limiting assembly 240 .

[0089] By providing the buffer pad 212 in this embodiment, the friction and collision between the screen cabinet and the mounting base 210 are reduced, thereby protecting the surface of the screen cabinet from damage.

[0090] like Figure 6 As shown, this embodiment further provides a substation electrical equipment transport device, including a vehicle body 100 , a gantry 110 is provided at the vehicle body 100 , and a limiting mechanism is installed on the upper part of the gantry 110 .

[0091] When this embodiment is used, the limiting mechanism at the mounting frame on the vehicle body 100 can effectively prevent the screen cabinet from shifting and falling off during transportation, thereby improving transportation safety and efficiency. During transportation, the first limiting assembly 220 and the second limiting assembly 240 of the limiting mechanism act together on the screen cabinet to effectively prevent it from shifting and falling off. At the same time, the design of the first locking assembly 230 and the second locking assembly 250 makes the limiting operation more convenient and efficient. During transportation, regardless of sharp turns or sudden braking, the limiting mechanism can ensure the stability and safety of the screen cabinet. At the same time, the buffer pad 212 further improves the protective effect of the screen cabinet touching the limiting mechanism during transportation, providing buffering and protection.

[0092] Example 3

[0093] like Figure 1-Figure 18 As shown, the embodiment 1 or 2 is the same as the embodiment 1 or 2, except that the embodiment also includes a protection mechanism 3 installed on the fork frame, the protection mechanism 3 includes a protection mechanism base plate 301, and the protection mechanism base plate 301 is provided with two sleeve plates 302 sleeved on the forks and two protection plates 303 arranged opposite to each other and capable of moving toward or away from each other, the protection plate 303 is located on the outer side of the sleeve plate 302 and the plate surface is arranged vertically.

[0094] The protective mechanism 3 in this embodiment can be directly designed based on the size of the fork frame of an existing conventional forklift during installation, so that it can be directly installed on an existing forklift without improving the structure of the forklift body 100, which can effectively control costs and has better applicability.

[0095] During use, it is only necessary to put the two socket plates 302 on the two forks. In the initial state, the protective plate 303 can be moved backwards until the screen cabinet can be placed on the socket plate 302, and then the two protective plates 303 are pressed against the side of the screen cabinet, that is, the side of the protruding fork of the screen cabinet, so that the end face can be protected to prevent the side of the screen cabinet from directly colliding with the wall or door frame when passing through a door or a narrow passage, thereby playing a better protective role.

[0096] Among them, in order to realize the toward or away movement of the two protective plates 303, a pull plate slide groove 304 with both ends extending to the end surface of the protective mechanism bottom plate 301 is opened in the middle part of the protective mechanism bottom plate 301, and the lower ends of the two protective plates 303 are connected with pull plates 305 arranged horizontally on the plate surface, and the ends of the pull plates 305 away from the protective plates 303 are slidably connected in the pull plate slide groove 304, and a tension spring 306 for driving the two pull plates 305 to move toward each other is connected between the two pull plates 305. Under the action of the tension spring 306, the relative movement of the two protective plates 303 can be realized, and the protective plates 303 can be pressed against the side of the screen cabinet to achieve protection stability.

[0097] In this embodiment, the transport device has better applicability. When facing outdoor transport of other larger electrical equipment, there is no need to remove the protective mechanism 3 from the fork. It is only necessary to store the protective plate 303, that is, the bottom of the protective plate 303 is rotatably connected to the end of the pull plate 305, and the protective plate 303 can be rotated to a position flush with the pull plate 305. At this time, the protective plate 303 can be stored in the pull plate slide groove 304 under the action of the tension spring 306. At this time, the transport device is a conventional forklift without a protective plate 303, which can transport different electrical equipment.

[0098] When the protective plate 303 and the pull plate 305 are rotationally connected, it is necessary to consider the rotation limit of the protective plate 303, that is, the first protective plate limiting mechanism provided in this embodiment, the first protective plate limiting mechanism includes an L-shaped square groove 307 arranged on the surface of the protective plate 303, and a through groove 308 extending to the bottom surface of the protective plate 303 is provided on the bottom surface of the L-shaped square groove 307, and a pull plate slot 309 opening upward is provided at the connecting end of the pull plate 305 and the protective plate 303. The first protective plate limiting mechanism also includes a sub-plate 310 arranged in the L-shaped square groove 307 and a card plate 311 connected to the lower end of the sub-plate 310 and inserted into the pull plate slot 309 through the through groove 308.

[0099] The upper end and the right end of the L-shaped square groove 307 extend to the upper end face and the right end face of the protective plate 303 respectively. The rear end face of the L-shaped square groove 307 is provided with an upper limit hole 312 and a lower limit hole 313 arranged up and down. The sub-plate 310 is provided with a limit plate 314 fixed at the upper limit hole 312 or the lower limit hole 313 by fastening bolts. When the limit plate 314 is connected to the upper limit hole 312, the clamping plate 311 is disengaged from the pull plate clamping groove 309. When the limit plate 314 is connected to the lower limit hole 313, the clamping plate 311 is clamped into the pull plate clamping groove 309.

[0100] The setting of the sub-plate 310 and the card plate 311 can realize the card plate 311 to be inserted into the pull plate slot 309, thereby realizing the rotation limit between the protective plate 303 and the pull plate 305, preventing the protective plate 303 from rotating relative to the pull plate 305, and keeping the protective plate 303 in a vertical state; when the card plate 311 is disengaged from the pull plate slot 309, the rotation limit of the two is released, and the protective plate 303 can be rotated to a position flush with the pull plate 305, and then received into the pull plate slot 304 under the action of the tension spring 306.

[0101] The operation process is also relatively simple, and it is only necessary to connect the limiting piece 314 on the sub-plate 310 with different limiting holes.

[0102] In addition, the width of the card plate 311 is smaller than the length of the pull plate slot 309. When the card plate 311 slides in the pull plate slot 309 along the length direction of the pull plate slot 309, it can drive the sub-plate 310 to extend or retract the L-shaped square slot 307. Through the design of this size width, it is possible to increase the length of the protective plate 303 through the sub-plate 310, so that the protective plate 303 can have better protective performance. In order to ensure the connection stability of the sub-plate 310 during the protection process, the upper limit hole 312 and the lower limit hole 313 can be designed to have two long holes along the length direction of the protective plate 303. The position of the sub-plate 310 relative to the protective plate 303 can be adjusted by connecting the limit plate 314 to different positions of the long hole.

[0103] In this embodiment, it is considered that it is difficult to limit the angular deviation of the screen cabinet on the fork by relying solely on the tension spring 306 to provide relative pulling force to the protective plate 303 so that it is pressed against the side of the screen cabinet, and the deviation of the screen cabinet will lead to the risk of falling off the fork. Therefore, a second protective plate limiting mechanism is provided in this embodiment. The second protective plate limiting mechanism includes a limiting socket 324 arranged on the side of the end of the pull plate 305, and also includes a limiting mechanism connecting seat 315 installed on the protective mechanism bottom plate 301. A rotatable limiting sleeve rod 316 is installed on the limiting mechanism connecting seat 315. A limiting threaded rod 317 is threadedly connected to both ends of the limiting sleeve rod 316. The limiting threaded rod 317 can drive the protective plate 303 to move toward or away from each other under the rotation of the limiting sleeve rod 316. It can limit the distance between the two protective plates 303 under the threaded limiting action of the limiting sleeve rod 316 and the limiting threaded rod 317, and then prevent the screen cabinet from deviating through the protective plate 303.

[0104] Specifically, the end of the limiting threaded rod 317 away from the limiting sleeve rod 316 is bent into an L shape and can be inserted into the limiting socket 324. When the limiting threaded rod 317 is inserted into the limiting socket 324, the limiting sleeve rod 316 can drive the two limiting threaded rods 317 to move toward or away from each other during rotation.

[0105] In addition, in order to prevent the limiting threaded rod 317 from being disengaged from the limiting socket 324 during the operation of the transport vehicle, a U-shaped connecting seat mounting groove 318 with an opening facing the insertion direction of the limiting threaded rod 317 into the limiting socket 324 is provided on the bottom plate 301 of the protection mechanism, and a rear limiting hole 319 and a front limiting hole 320 arranged along the opening direction of the connecting seat mounting groove 318 are provided on the side surface of the connecting seat mounting groove 318. The limiting mechanism connecting seat 315 is installed in the connecting seat mounting groove 318. When the limiting mechanism connecting seat 315 is connected to the front limiting hole 320, the limiting threaded rod 317 is inserted into the limiting socket 324. When the limiting mechanism connecting seat 315 is connected to the rear limiting hole 319, the limiting threaded rod 317 is disengaged from the limiting socket 324.

[0106] The limiting mechanism connecting seat 315 is provided with a limiting post 321 that cooperates with the rear limiting hole 319 or the front limiting hole 320 and a post installation groove 322 for installing the limiting post 321. There are two limiting posts 321 and a post reset spring 323 is connected between the two limiting posts 321. The two limiting posts 321 can extend out of the post installation groove 322 and be inserted into the rear limiting hole 319 or the front limiting hole 320 under the action of the post reset spring 323.

[0107] The two limit clamping posts 321 are inserted into the limit holes on both sides of the connection seat installation groove 318, and the upper ends of the limit clamping posts 321 can extend out of the clamping post installation groove 322. The operator can operate the two limit clamping posts 321 with one hand to switch different limit holes. In addition, the limit mechanism connection seat 315 can only slide along the depth direction of the connection seat installation groove 318 in the connection seat installation groove 318, and cannot rotate in the connection seat installation groove 318, ensuring that the limit threaded rod 317 can still be aligned and plugged in after being separated from the limit plug hole 324.

[0108] By inserting the limit clamping column 321 into different limit holes, it is selected whether the limit threaded rod 317 is inserted into the limit plug hole 324, so as to adjust the distance and fix the distance when inserted. When not inserted, the limit mechanism connecting seat 315 can continue to be connected to the connecting seat installation groove 318, and there is no need to store it separately.
