[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 making creative work are within the scope of protection of the present invention.

[0020] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a scissor lift truck steering mechanism assembly tool and a scissor lift truck steering mechanism provided by the present invention; Figure 2 for Figure 1 The structural schematic diagram of the steering mechanism assembly tool of the scissor lift truck shown in the figure. The steering mechanism assembly tool of the scissor lift truck comprises a trolley 1, a lifting bracket 3 fixed on the trolley 1 and a driving assembly 7 for driving the lifting bracket 3 to rise and fall, and a steering mechanism 10 is placed on the lifting bracket 3.

[0021] The cart 1 includes a base frame 11, a handrail 13 fixedly connected to the base frame 11, and a fixed wheel 15 at the front end and a universal wheel 17 at the rear end provided below the base frame 11. The handrail 13 is pushed to move the cart 1, and the universal wheel 17 is used to adjust the position of the tooling to facilitate the assembly of the steering mechanism 10.

[0022] The lifting bracket 3 is fixed on the base frame 11. The lifting bracket 3 includes a lifting platform 31, a track 33 and two bearing frames 35. The lifting platform 31 is fixed on the base frame 11 of the cart 1 and connected to the driving assembly 7. The track 33 is U-shaped and fixed on the lifting platform 31, and the two openings of the track 33 are arranged opposite to each other. The two bearing frames 35 are rollingly connected to the track 33 and are arranged back to back. The steering mechanism 10 is placed on the bearing frames 35. The driving assembly 7 drives the lifting platform 31 to move up and down to drive the bearing frames 35 on the track 33 to move up and down, so as to realize the lifting and lowering of the steering mechanism 10 to different heights to achieve the purpose of assembling the steering mechanism 10. Moreover, since the two bearing frames 35 can slide at the same time, the distance between the two bearing frames 35 can be adjusted by adjusting the two bearing frames 35 on the track 33 separately or simultaneously, so as to adapt to steering mechanisms 10 of different widths, thereby adapting to various different scissor lift models.

[0023] The lifting platform 31 includes a frame 311, a guide column 313 fixedly connected to the frame 311, a guide sleeve 315 sleeved on the guide column 313, and an outrigger 317 fixedly connected to the bottom end of the guide sleeve 315. The track 33 is fixed on the outrigger 317. The guide sleeve 315 is connected to the driving component 7. The driving component 7 drives the guide sleeve 315 to move up and down, so that the outrigger 317 performs a lifting motion, thereby lifting the track 33 fixed on the outrigger 317, and further lifting the two supporting frames 35 rollingly connected to the track 33.

[0024] The guide posts 313 are arranged in two intervals, and the tops of the two guide posts 313 are connected with a connecting plate 314 . The connecting plate 314 is used to improve the connection rigidity between the two guide posts 313 .

[0025] See also Figure 3 ,for Figure 1 The structural schematic diagram of the carrier 35 is shown. The carrier 35 comprises a bracket 351, rolling wheels 352 arranged on both sides of the bracket 351, and a frame seat 353 and a wheel seat 354 arranged on the bracket 351. The rolling wheels 352 are embedded in the track 33. The rolling wheels 352 roll in the track 33 to adjust the distance between the two carriers 35 so as to adapt to steering mechanisms of different widths. The structure is flexible and can be applied in a wide range of applications.

[0026] Specifically, in this embodiment, the rolling wheel 352 is a rolling bearing. Four limit blocks 37 are arranged in each of the tracks 33 so that the rolling bearing can roll between two limit blocks 37 .

[0027] There is a height difference between the frame seat 353 and the wheel seat 354 . A plurality of inclined universal balls 355 are provided on the wheel seat 354 . The wheels of the steering mechanism 10 are located on the universal balls 355 , and the frame of the steering mechanism 10 is placed on the frame seat 353 .

[0028] The universal ball 355 is respectively arranged on two plates 357 inclined toward the middle position, and the plates 357 are fixed on the wheel seat 354. The two plates 357 are arranged in a V shape, so that the tires arranged on the universal ball 355 can slide to adjust the angle and automatically center, so that the tires sink to the bottom of the V, so that the steering mechanism can be better positioned on the carrier 35.

[0029] The frame seat 353 includes a support plate 3531, a pad 3532 fixed on the bottom plate 3531, and two stop blocks 3533 arranged at the corners of the support plate 3531. The stop blocks 3533 are in a right-angle shape and are used to stop the frame from sliding and improve the placement stability of the steering mechanism.

[0030] Specifically, in this embodiment, the pad 3532 is a polyurethane plate, which has certain elasticity and good shock resistance. It is used for buffering and coating protection of the steering mechanism to be installed. When the steering mechanism is installed, the frame contacts the pad 3532, and the pad 3532 forms a buffer with the frame of the steering mechanism, which effectively protects the frame from damage.

[0031] In another embodiment, the carrier 35 further includes a manual adjustment handle 358, which is fixedly connected to the wheel seat 354 and is used to adjust the vertical distance between the wheel seat 354 and the wheel. In this way, the vertical height of the carrier 35 can be fine-tuned to ensure a high degree of installation fit between the steering mechanism 10 and the carrier 35.

[0032] The driving assembly 7 is fixed on the base frame 11. The driving assembly 7 includes a power supply 71 fixed on the cart 1, a power unit 73, and a driving unit 75 connected to the power unit 73. The power supply 71 provides electrical energy to the power unit 73. One end of the driving unit 75 is fixed on the cart 1, and the other end is rotatably connected to the lifting bracket 3 to drive the lifting bracket 3 to move up and down. The structure is flexible and the operability is strong. Specifically, one end of the driving unit 73 is fixed on the base frame 11, and the other end is rotatably connected and fixed to the guide sleeve 315 through an intermediate connecting bracket to drive the entire lifting bracket 3 to move up and down.

[0033] Specifically, in this embodiment, the power source 71 is a battery, the power unit 73 is a hydraulic power unit, the power unit 73 integrates a motor, a pump, a fuel tank and a control valve, and the drive unit 75 is a cylinder. The self-powered system is adopted, and no external power supply is required.

[0034] The assembly process of the scissor lift truck steering mechanism assembly tool is as follows: the first step is to hoist the various components of the steering mechanism 10 onto the carrier frame 35 in sequence to complete the general assembly; the second step is to push the handle and move the cart 1 to move the work to the chassis to be installed and align the chassis installation station; the third step is to control the oil cylinder to lift the steering mechanism 10 to approach the chassis installation station; the fourth step is to fine-tune the manual adjustment handle 358; the fifth step is to control the oil cylinder to lift again to completely install the steering mechanism 10 into the chassis installation station.

[0035] The scissor lift steering mechanism assembly tool provided in the embodiment of the present invention comprises a trolley, a lifting bracket fixed on the trolley, and a driving component for driving the lifting bracket to rise and fall. The steering mechanism is placed on the lifting bracket, and the lifting platform is driven to rise and fall by the driving component to drive the supporting frame on the track to rise and fall, thereby completing the assembly of the steering mechanism. No manual installation is required, thus reducing labor intensity and increasing installation efficiency. The distance is adjusted by two rolling supporting frames, so that it can be used for steering mechanisms of different widths, and thus can adapt to the installation of more scissor lift models, greatly improving the adaptability of the tool.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
