Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of platform lift truck, and particularly relates to a hydraulic outrigger structure and platform lift truck. BACKGROUND

[0002] The platform lift truck is a vehicle with a lifting platform, which is mainly used for lifting personnel and equipment to a certain height for high-altitude operation. The platform lift truck mainly comprises a base, a support rotatably installed on the base, and a platform guard moved up and down by the support driven by an oil cylinder. A plurality of hydraulic outriggers are installed around the base to provide necessary stability and support force, so that the lift truck does not overturn during operation and the safety of the operator is ensured.

[0003] The support range of the traditional hydraulic outrigger is mainly concentrated around the base of the lift truck. The support effect of the overall structure after the support is stretched is not good, especially when the support is stretched to a large angle or height. The support force of the hydraulic outrigger will be weakened due to the lever action, and the center of gravity of the platform will also shift with the lifting of the platform, which can easily lead to a decrease in the stability of the support. In addition, most lift trucks are not convenient to move the platform on the lift truck with the help of the hydraulic outrigger after lifting the platform, which leads to the need to frequently adjust the position of the vehicle during position changing operation, thereby increasing the complexity of the operation.

[0016] A platform lifting vehicle comprises:

[0018] A carrier plate, the output end of the hydraulic cylinder two can drive the carrier plate to slide on the guide rail one.

[0019] A support, the support comprises a plurality of hinged rods hingedly connected with each other, and a platform is installed on the top hinged rod of the support.

[0020] Two splicing seats are detachably installed at the ends of the vehicle base, and two guide rails two are fixedly connected to the splicing seats and aligned with the corresponding position guide rails one.

[0021] Further, two track seats slidably connected with the corresponding position guide rails one and guide rails two are slidably clamped on the bottom surface of the carrier plate, and a transmission block movably inserted with the carrier plate is fixedly connected to the output end of the hydraulic cylinder two.

[0022] Further, a connecting seat is fixedly connected to each end of the vehicle base, and a pin shaft two is movably inserted between the splicing seat and the corresponding position connecting seat.

[0023] Further, two moving wheels are rotatably connected to each end of the vehicle base and the splicing seat, and a mounting hole movably inserted with the pin shaft two is formed in the splicing seat.

[0024] Compared with the prior art, the beneficial effects of the present application are:

[0025] 1. By fixing a plurality of hydraulic leg structures on the load plate of the vehicle base, the hydraulic leg structure comprises a fixed seat fixed with the load plate, a cross beam is rotatably installed on the fixed seat, one end of the cross beam is slidably connected with a movable beam, one end of the movable beam is fixed with a movable seat, a hydraulic cylinder one is slidably connected with the inner side of the movable seat, and a diagonal brace is placed at the clamping block position of the plurality of movable beams on the same side of the vehicle base. When the lifting truck is working, the output end of the hydraulic cylinder one is elongated to make the support disc abut against the ground. After the support disc abuts against the ground, the output end of the hydraulic cylinder one is continuously elongated, so that the hydraulic cylinder body moves upward under the reaction force applied to the support disc by the ground, and the movable beam rotates upward with the hydraulic cylinder body. The movable beam supports the lifting truck support through the diagonal brace from both sides of the support, so that the hydraulic support structure can support and fix the lifting truck top support related structure by means of the diagonal brace while supporting the lifting truck bottom load plate and the vehicle base related structure, which helps to improve the stability of the lifting truck support, vehicle base and load plate overall structure.

[0026] 2. By fixing a splicing seat at both ends of the vehicle base, a proper number of hydraulic support structures are installed on both sides of the splicing seat and the load plate, and a diagonal brace is installed between the plurality of hydraulic leg structures on the same side of the vehicle base and the support. The output end of the plurality of hydraulic cylinders one installed on the load plate is retracted so that the support disc does not contact the ground. The output end of the hydraulic cylinder two can be retracted or elongated to make the transmission block slide the load plate from the guide rail one to the guide rail two, so as to adjust the position of the platform on the support along the guide rail one left and right without moving the lifting truck. This facilitates users to change position and work on the platform. During the movement of the load plate with the support and platform, the output end of the hydraulic cylinder one installed on the splicing seat is slightly elongated after the support disc abuts against the ground, so that the hydraulic leg structure on the splicing seat can continue to support the diagonal brace outside the support, which is beneficial to improve the stability of the translation of the load plate with the support.

[0027] After the load plate with the support and platform slides to the guide rail two of the splicing seat, the output end of the plurality of hydraulic cylinders one installed on the load plate is elongated, and the output end of the hydraulic cylinder one installed on the splicing seat is shortened, so that the hydraulic leg structure on the load plate supports and fixes the support through the diagonal brace alone. Continue to elongate the output end of the hydraulic cylinder one on the load plate, and then the plurality of hydraulic leg structures fixed on the periphery of the load plate lift the load plate from the vehicle base. The weight of the load plate, support and platform is no longer applied to the vehicle base. Then the moving wheels on the vehicle base and the splicing seat roll to move the vehicle base and the splicing seat as a whole in the direction away from the load plate, so that the guide rail two under the load plate can be moved out to continue to move along the guide rail two. Since the load plate, support and platform are supported above the vehicle base by the hydraulic leg structure on the load plate and the diagonal brace, the movement of the vehicle base does not affect the stability of the support and platform. During the movement of the load plate, the bottom end of the telescopic rod can slide along the shaft, so that the support is supported and held by the diagonal brace when moving to different positions.

[0028] Through the alternately supporting the support by the splicing seat and the hydraulic outrigger structure on the carrier plate, the carrier plate can stably translate with the support and the platform on the vehicle base, and the vehicle base can stably move on the ground relative to the stationary carrier plate, so that the carrier plate can stably translate with the support and the platform at a long distance on the premise that the lifting vehicle does not move, thereby improving the convenience of the lifting vehicle platform movement while improving the diversity of the hydraulic outrigger structure auxiliary platform movement function.

[0029] 3、The side of the inclined support panel is slidably connected with a plurality of positioning columns through a sliding block, the plurality of positioning columns can be respectively inserted into the intersection corners of the two hinged rods of the support, and a connecting spring is fixed between the positioning column and the panel, the connecting spring enables the sliding block to have a tendency to move with the positioning column to the intersection corners of the two hinged rods, so that when the support is slightly stretched or contracted to fine-tune the height of the platform, the plurality of positioning columns can always adapt to the size of the position change of the hinged rods and be positioned and abutted at the intersection corners, and finally the electromagnet on the panel is electrified to adsorb and fix the plurality of sliding blocks, so that the plurality of fixed positioning columns limit and fix the hinged rods stretched to the appropriate position from the intersection corner position, which helps to improve the firm support of the inclined support on the support in various stretched states.

[0042] The hydraulic support leg structure comprises a locking device 100, the locking device 100 comprises a fixed seat 110 fixedly installed with the carrier plate 700, the bottom of the fixed seat 110 is rotationally connected with a cross beam 200, the bottom of the cross beam 200 is fixedly connected with a fixed block 220, one end of the cross beam 200 is slidingly and rotationally connected with a movable beam 300, one end of the movable beam 300 is fixedly connected with a movable seat 310, a square tube 400 is slidingly clamped in the movable seat 310, a hydraulic cylinder one 410 is fixedly arranged in the square tube 400, a support disc is fixedly arranged at the output end of the hydraulic cylinder one 410, the hydraulic cylinder one 410 is slidingly connected with the fixed block 220, the movable beam 300 is clamped with a diagonal brace 500, and the diagonal brace 500 can be supported between the support and the carrier plate 700 of the vehicle base 600.

[0043] Specifically, by designing the traditional hydraulic support leg structure into the form of the cross beam 200, the movable beam 300 and the hydraulic cylinder one 410, the output end of the hydraulic cylinder one 410 is elongated to abut against the ground, and then the output end of the hydraulic cylinder one 410 is continuously elongated, so that the cylinder body moves in the direction of the support along with the movable beam 300 and the diagonal brace 500 under the action of the reaction force of the ground on the hydraulic cylinder one 410, and then the diagonal brace 500 can be supported and fixed outside the support, so that the hydraulic support leg structure can support and fix the vehicle base 600, the carrier plate 700 and the support on the lifting vehicle at multiple positions, which helps to improve the overall stability of the lifting vehicle after lifting.

[0044] By arranging one splicing seat 900 at each end of the vehicle base 600, and arranging one hydraulic support leg structure on each side of the splicing seat 900, the hydraulic support leg structures on the splicing seat 900 can support the diagonal brace 500 to support the diagonal brace 500 on both sides of the support, the output end of the hydraulic cylinder two 620 is elongated or contracted to make the carrier plate 700 move along with the support and the platform 810 to slide from the vehicle base 600 to the splicing seat 900, so as to adjust the position of the platform 810 for operation, and then the hydraulic support leg structures on the carrier plate 700 can support the diagonal brace 500 to support and fix the support, and at the same time, the carrier plate 700 can slightly move upward along with the support and the platform 810 as the hydraulic cylinder one 410 of the hydraulic support leg structures on the carrier plate 700 is continuously elongated, so that the vehicle base 600 moves away from the carrier plate 700, and the splicing seat 900 previously moved below the carrier plate 700 can be extended again, which facilitates the subsequent movement of the carrier plate 700 along the splicing seat 900, so that the carrier plate 700 can move a long distance along with the support and the platform 810.

[0045] As Figure 3As shown, in the embodiment, two positioning blocks 120 are fixed outside the fixing base 110 of the locking device 100 at an angle of 90 degrees, and a T-shaped pin shaft 130 is movably inserted between the corresponding positioning blocks 120 and the cross beam 200, so that the position of the cross beam 200 after rotation adjustment can be fixed in position.

[0046] In the embodiment, referring to Figure 8 , in the initial state, the movable beam 300 is slidably accommodated in the cross beam 200, and the cross beam 200 is rotated to abut against the outside of the carrier plate 700. At this time, the pin shaft 130 is inserted between the cross beam 200 and the positioning block 120 close to the carrier plate 700, so that the hydraulic leg structure can be accommodated and fixed outside the lifting vehicle. Referring to Figure 2 , when the movable beam 300 extends from the inside of the cross beam 200, the cross beam 200 is unfolded at an angle of 90 degrees from the outside of the carrier plate 700, and then the pin shaft 130 between the cross beam 200 and the positioning block 120 close to the carrier plate 700 is pulled out, and then the pin shaft 130 is inserted between the cross beam 200 and the positioning block 120 away from the carrier plate 700. At this time, the pin shaft 130 helps to fix the unfolded hydraulic leg structure.

[0047] As shown in Figure 2 , Figure 3 and Figure 8 , in the embodiment, a rectangular hole 210 is formed through the outside of the cross beam 200, one end of the rectangular hole 210 is connected and formed with a circular hole 211, one end of the movable beam 300 is inserted and fixed with a square shaft 320, the square shaft 320 is slidably connected with the rectangular hole 210, the square shaft 320 is rotatably connected with the circular hole 211, the outside of the square tube 400 is fixed with two rotating shafts 420, and the two sides of the movable seat 310 are both formed with a slot-shaped hole slidably and rotatably connected with the rotating shaft 420, and the bottom of the fixed block 220 is slidably connected with a moving column 221 slidably sleeved with a hydraulic cylinder 410.

[0048] In the embodiment, referring to Figure 8 , at this time, the hydraulic leg structure is in the accommodation state, the end of the square shaft 320 slides to one end of the rectangular hole 210 away from the circular hole 211, the rotating shaft 420 is arranged at one end of the slot-shaped hole close to the cross beam 200, and the moving column 221 is slidably inserted into the inside of the fixed block 220. When the hydraulic leg structure is stretched, referring to Figure 3 , the end of the square shaft 320 moves and slides to the position of the circular hole 211 along with the movable beam 300, at this time, the diameter of the circular hole 211 meets the rotation of the square shaft 320, so that the movable beam 300 can be rotated around the square shaft 320 in the later period, and the moving column 221 is slidably pulled out from the inside of the fixed block 220. When the output end of the hydraulic cylinder 410 is elongated, referring to Figure 2At this time, the cylinder body of the hydraulic cylinder 410 can deflect with the movable beam 300 to the direction of the lifting vehicle, the movable beam 300 rotates around the square shaft 320, and helps the movable beam 300 to support and fix or support the support frame with the inclined support 500, so as to prevent the support frame from swinging after being stretched.

[0049] As shown in Figure 1 , Figure 3 and Figure 4 , in the embodiment, the top surface of the movable beam 300 of the hydraulic leg structure is fixed with two clamping blocks 311, and the inclined support 500 is placed on the movable beam 300 of the plurality of hydraulic leg structures on the same side of the vehicle base 600, the inclined support 500 includes the shaft rod 510 clamped and placed between the adjacent two clamping blocks 311, the outer side of the shaft rod 510 is rotationally connected with the telescopic rod 520, the telescopic rod 520 includes the positioning rod 521 rotationally connected with the shaft rod 510, one end of the positioning rod 521 is fixed with the connecting sleeve 522, the inside of the connecting sleeve 522 is slidingly clamped with the movable rod 523, the top of the movable rod 523 is rotationally connected with the panel 530, one side of the panel 530 is slidingly clamped with the plurality of sliding blocks 540, the outer side of the sliding block 540 is fixed with the positioning column 541, the inside of the panel 530 is embeddedly fixed with the electromagnet 550 capable of adsorbing and fixing the plurality of sliding blocks 540, and the sliding block 540 and the panel 530 are fixed with the connecting spring 542.

[0050] In the embodiment, referring to Figure 1 , after the support frame and the hydraulic leg structure of the lifting vehicle are stretched and opened, the inclined support 500 is installed between the support frame and the hydraulic leg structure, specifically, the four positioning columns 541 on the panel 530 can be inserted into the cross corner positions of the cross-arranged hinged rods 800, and then the shaft rod 510 is placed into the clamping position between the plurality of clamping blocks 311 and the movable beam 300 on the same side of the lifting vehicle, at this time, the telescopic rod 520 is in an elongated state, and the bottom end of the movable rod 523 is not in contact with the inner bottom surface of the connecting sleeve 522, when the hydraulic leg structure is needed to support the lifting vehicle for work, referring to Figure 1 , the output ends of all the hydraulic cylinders 410 are elongated to support the support disc on the ground, at the same time, the cylinder body is moved upward along the moving column 221 under the ground reaction force, the square tube 400 on the cylinder body drives the movable beam 300 to rotate around the square shaft 320 through the rotating shaft 420, so that the movable beam 300 is gradually inclined, at this time, the movable beam 300 pushes the positioning rod 521 from the bottom end of the positioning rod 521 to make the telescopic rod 520 shorter, until the bottom end of the movable rod 523 contacts the inner bottom surface of the connecting sleeve 522, and the output end of the hydraulic cylinder 410 continues to elongate;

[0051] When the bottom end of the movable rod 523 contacts the inner bottom surface of the connecting sleeve 522, the stability of the support can be improved in two cases. Case one is that the support is fixed in position, and the support of the lifting vehicle and the base 600 of the vehicle do not move during operation. When the length of the telescopic rod 520 cannot be shortened any more, the output end of the hydraulic cylinder I 410 is continued to be elongated, so that the telescopic rod 520 abuts against the support through the panel 530. At this time, the bottom end of the movable rod 523 abuts against the inner bottom surface of the connecting sleeve 522, and the electromagnet 550 on the panel 530 is electrified to adsorb and fix the position of the sliding block 540 and the positioning column 541. The side of the sliding block 540 close to the electromagnet 550 is embedded with an iron block, which facilitates the adsorption and fixation of the sliding block 540 by the electrified electromagnet 550, so that the entire diagonal brace 500 supports and fixes the support and the load plate 700 of the base 600 of the vehicle in the operating position.

[0052] Case two is that the diagonal brace 500 only supports and holds the support, so that the support can be slightly adjusted in position or the load plate 700 needs to be displaced on the base 600 of the vehicle. At this time, the ground of the movable rod 523 on the telescopic rod 520 is in a close position relationship with the inner bottom surface of the connecting sleeve 522, and the panel 530 is limited and held in the hinged position of the support. When the support is slightly lowered in height, the output end of the hydraulic cylinder I 410 can be slightly contracted, so that the movable beam 300 with the telescopic rod 520 is lowered to adapt to the height reduction of the support. The positioning column 541 on the panel 530 can also slide on the panel 530 by the compression elastic force of the connecting spring 542 to the intersection of the hinged rod 800, so as to adapt to the change of the intersection position of the hinged rod 800 when the height of the support is slightly adjusted.

[0053] In the embodiment, the lengths of the positioning rod 521 and the movable rod 523 on the telescopic rod 520 can be pre-processed to appropriate lengths according to the positions of supporting different lifting vehicle supports, so that the overall length of the telescopic rod 520 can meet the appropriate hinged rod 800 position of the panel 530 supported on the support after the support is stretched.

[0054] As shown in Figure 1 and Figure 4 In the embodiment, the both ends of the shaft rod 510 are fixed with circular blocks, which can abut against the outer side of the clamping block 311 to prevent the shaft rod 510 from moving along the axial direction. The inner bottom surface of the connecting sleeve 522 is provided with a pressure sensor 524 of the prior art. When the movable rod 523 abuts against the pressure sensor 524 of the connecting sleeve 522, the pressure sensor 524 can read the pressure value, which facilitates the user to understand the force of the diagonal brace 500 supported and fixed on the support. If the pressure sensor 524 detects pressure, it means that the diagonal brace 500 plays a role in supporting and abutting against the support. If the pressure sensor 524 does not detect pressure, it means that the diagonal brace 500 plays a role in supporting and holding the support.

[0055] As shown inFigure 6 and Figure 7 As shown, in this embodiment, the bottom surface of the carrier plate 700 is slidably engaged with two rail seats 710, which are respectively slidably connected to the corresponding guide rail 610 and guide rail 910. Both sides of the rail seat 710 are fixed with limiting protrusions. The inner side of the carrier plate 700 near the limiting protrusions is provided with a limiting groove 720 with a width larger than the limiting protrusion. The limiting protrusion slides up and down inside the limiting groove 720, which can allow the carrier plate 700 to detach from the vehicle base 600 or press against the vehicle base 600. The output end of the hydraulic cylinder 620 is fixed with a transmission block. The bottom surface of the carrier plate 700 is provided with a transmission hole 730 with a length larger than the transmission block. The transmission hole 730 is movably inserted into the transmission block, so that the output end of the hydraulic cylinder 620 can always drive the carrier plate 700 to move back and forth through the transmission block during the up and down movement of the carrier plate 700.

[0056] In this embodiment, when it is necessary to move the vehicle base 600 relative to the stationary carrier plate 700, refer to Figure 5 At this time, the carrier plate 700 can move upward under the support of the hydraulic support structure. There is a gap between the carrier plate 700 and the track seat 710. The weight on the carrier plate 700 is no longer applied to the guide rail 610 of the vehicle base 600. Thus, the displacement of the vehicle base 600 does not affect the carrier plate 700 from continuing to support the bracket and platform 810, nor does it cause the carrier plate 700 to move synchronously.

[0057] like Figure 5 As shown, in this embodiment, both ends of the vehicle base 600 are fixed with connecting seats 630. A second pin 631 is movably inserted between the splicing seat 900 and the corresponding connecting seat 630. The splicing seat 900 is provided with a mounting hole 920 for movably inserting the second pin 631. After the connecting seat 630 is inserted into the splicing seat 900, the second pin 631 is then inserted between the connecting seat 630 and the splicing seat 900 through the mounting hole 920, thereby fixing the splicing seat 900 to the vehicle base 600.

[0058] In this invention, such as Figure 1 and Figure 5 As shown, two movable wheels are rotatably connected to both ends of the vehicle base 600, and movable wheels of the same size are also rotatably connected to both sides of the splicing seat 900. Furthermore, a drive motor that can drive the movable wheels to roll is fixed inside the vehicle base 600, thereby enabling the movable wheels to drive the lifting vehicle to move. A hydraulic cylinder that can drive the support to extend is installed on the top surface of the carrier plate 700, and a guardrail is fixed to the outside of the platform 810. The above parts are known contents of the lifting vehicle, and the working principle of the specific related components will not be described in detail.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
