Detailed Implementation

[0024] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0025] like Figures 1-6As shown, the multi-functional lifting vehicle for product oil tankers includes a chassis 1; it also includes: Platform 4, and a scissor support mechanism 5 is installed between platform 4 and chassis 1; The top and bottom left sides of the scissor support mechanism 5 are hinged to the bottom side of the chassis 1 and the platform 4, respectively; the top and bottom right sides of the scissor support mechanism 5 are each rotatably equipped with rollers 9. Guide section 8, the guide section 8 is provided with a horizontal groove with a top opening, the platform 4 and the chassis 1 are both provided with guide sections 8; the roller 9 is slidably installed in the horizontal groove, the bottom surface of the horizontal groove is provided with a lubricating oil layer that fits against the bottom surface of the roller 9. Oil storage assembly 10, wherein the oil storage assembly 10 is installed at the bottom of the guide portion 8; Pull-up component 6 is installed on chassis 1 and is connected to the bottom right side of scissor support mechanism 5.

[0026] In practice, the right bottom of the scissor support mechanism 5 is pulled to the left by the pulling component 6, which raises the platform 4; while the pulling component releases the pull on the right bottom of the scissor support mechanism 5, and the platform 4 is lowered by the gravity of the platform 4 and the scissor support mechanism 5, thus achieving the lifting and lowering adjustment.

[0027] This lifting vehicle has multiple functions. In addition to the lifting function, the right side of the scissor support mechanism 5 can slide laterally to achieve lifting. The lateral movement position adopts a rotating roller 9 structure, and a lubricating oil layer is set at the transverse groove of the lateral sliding position of the roller 9 to provide lubrication for rolling, thereby reducing the wear of lateral movement and playing a role in lubrication and reducing wear.

[0028] Furthermore, an oil storage component 10 is provided. When too much lubricating oil is added to the transverse groove, the oil storage component 10 can extract some of the oil from the groove and store it. When the oil in the transverse groove is insufficient, the oil stored in the oil storage component 10 can be poured back into the transverse groove. This avoids the problem of having to drain the oil from the top of the transverse groove after adding too much oil, which would otherwise be inconvenient.

[0029] like Figures 1-2As shown, the scissor support mechanism 5 consists of multiple scissor arms distributed at equal intervals along the vertical direction. Each pair of adjacent scissor arms is hinged to each other on the same side (i.e., the left sides of two scissor arms are hinged together, and the right sides are hinged together). Each scissor arm is composed of a first rod 501 and a second rod 502, which are arranged intersectingly, and the intersection points of the first rod 501 and the second rod 502 are hinged together. By pulling the bottom right side of the scissor support mechanism 5 to the left, the intersecting first rod 501 and second rod 502 are folded, thus raising the mechanism.

[0030] like Figure 1 , Figure 2 as well as Figure 4 As shown, the pulling assembly 6 includes a winding and unwinding structure; the winding and unwinding structure is connected to a steel wire rope 602, and an end frame 603 is fixedly connected to the end of the steel wire rope 602 away from the winding and unwinding structure, and the end frame 603 is fixedly installed on the bottom of the chassis 1; a rotating rod 605 is rotatably installed on the bottom right side of the scissor support mechanism 5, and a pulley 604 is fixedly sleeved on the rotating rod 605, and the steel wire rope 602 passes around the pulley 604.

[0031] The winding and unwinding structure includes a first support frame 601; the first support frame 601 is fixedly installed above the chassis 1, and a motor 607 is fixedly installed on the rear side of the first support frame 601. The output shaft end of the motor 607 is connected to a drum 606 through a coupling, and the drum 606 is connected to a wire rope 602.

[0032] like Figure 4 As shown, a second support frame 608 is provided on one side of the first support frame 601; the second support frame 608 is fixedly installed on the chassis 1, and a guide wheel 609 is rotatably installed on the second support frame 608, and the wire rope 602 passes around the guide wheel 609.

[0033] Among them, an electromagnetic brake is installed on the output shaft of motor 607 to ensure safe locking when power is cut off.

[0034] When motor 607 drives drum 606 to rotate and wind up wire rope 602, wire rope 602 drives pulley 604 to move to the left, thereby moving the bottom right side of scissor support mechanism 5 to the left, raising scissor support mechanism 5. After raising, motor 607 is locked by electromagnetic brake to maintain the raised height position. When motor 607 drives drum 606 to rotate and wind up wire rope 602, the weight of platform 4 and scissor support mechanism 5 causes the right side of scissor support mechanism 5 and roller 9 to move to the right, and pulley 604 and rotating rod 605 move to the right together, lowering scissor support mechanism 5. After lowering, motor 607 is locked by electromagnetic brake to maintain the lowered height position.

[0035] The wire rope 602 is made of high-strength galvanized steel wire rope. Through the above design, the expansion and contraction of the scissor support mechanism 5 are achieved by the winding and unwinding of the wire rope 602. Guide wheels 609 are provided on the path of the wire rope 602 to provide guidance.

[0036] like Figures 5-6 As shown, the guide part 8 is formed by a U-shaped strip 801 and a fixed frame 802; the inner wall of the U-shaped strip 801 and the inner wall of the fixed frame 802 form a transverse groove.

[0037] like Figure 6 As shown, the oil storage assembly 10 includes an oil cylinder 1001; the oil cylinder 1001 is fixedly installed to the bottom of the fixing frame 802, the top of the oil cylinder 1001 is provided with a connecting nozzle 1002, the connecting nozzle 1002 communicates with the bottom of the transverse groove, and a piston 1003 is connected inside the oil cylinder 1001, and the piston 1003 is connected to a driving component.

[0038] The driving component includes a screw 1004; the top end of the screw 1004 is rotatably connected to the piston 1003, and a nut 1005 is fixedly installed at the bottom of the oil cylinder 1001, with the screw 1004 threadedly connected to the nut 1005; a grip plate 1006 is fixedly installed at the bottom end of the screw 1004.

[0039] Lubricating oil is poured in through the opening at the top of the cross groove to form a lubricating oil layer at the bottom of the cross groove. However, if too much oil is poured in, there is a risk of spillage during the use of the entire lifting vehicle. The oil storage component 10 is installed to suck up excess oil and store it, thus preventing the oil from spilling out of the opening at the top of the cross groove.

[0040] When the oil storage assembly 10 extracts oil for storage, the screw 1004 and nut 1005 are screwed together by rotating the grip 1006 in the forward direction. The screw 1004 drives the piston 1003 to move downward, so that the oil cylinder 1001 draws oil from the horizontal groove through the connecting nozzle 1002.

[0041] When the oil in the transverse groove is insufficient, the screw 1004 and nut 1005 are screwed together by rotating the grip plate 1006 in the reverse direction. The screw 1004 drives the piston 1003 to move upward. The piston 1003 pushes the oil in the oil cylinder 1001 into the transverse groove through the connecting nozzle 1002 to replenish the oil in the transverse groove.

[0042] like Figures 1-2As shown, casters 2 are installed at each of the four corners of the bottom of the chassis 1. The chassis 1 is welded from steel plates, and the four casters 2 at the bottom enable the movement and steering of the lifting vehicle. The casters 2 have locking brake devices that lock during operation. A handrail 3 is fixedly installed on the top of one side of the chassis 1. By pushing or pulling the handrail 3, the operator can move and turn the entire lifting vehicle on the ground via the casters 2.

[0043] like Figures 1-2 As shown, a battery 7 is fixedly mounted on the top side of one side of the chassis 1, and a control panel is provided on the top of the battery 7. The battery 7 is used for power supply, and the control panel is used for controlling the motor 607. The battery 7 is a 48V / 200Ah lithium iron phosphate battery pack, equipped with a BMS battery management system, which has overcharge, over-discharge, and overcurrent protection functions and supports fast charging.

[0044] The 607 motor is a 48V DC brushless motor with a rated power of 5kW and a rated speed of 3000rpm. It is equipped with a planetary reducer with a reduction ratio of 1:40 and an output torque of ≥400N·m.

[0045] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
