[0002] Low-level transporters are mainly used for automobile maintenance. For example, when a car engine breaks down, it needs to be disassembled for maintenance. However, since the engine is large in size and heavy in weight, manual transportation is not only time-consuming and labor-intensive, but also prone to accidents. Therefore, using a low-level transporter to transport the engine can significantly improve convenience.

[0021] Figure 2 This is an exploded view of the low-level conveyor provided in this embodiment. DETAILED DESCRIPTION

[0022] Combination Figure 1 to Figure 2The low-level conveyor of the utility model is further described.

[0023] A low-level conveyor includes a base 1, a lifting arm 2 arranged on the base 1 and a pallet assembly 3 arranged on the upper end of the lifting arm 2, wherein the pallet assembly 3 includes a top plate 31, a mounting frame 32 and a connecting seat 36.

[0024] The top plate 31 is hinged on the top of the mounting frame 32 and can rotate in the left and right direction relative to the mounting frame 32. The mounting frame 32 is provided with a plurality of lifting support columns 33 that can support the top plate 31 after the left and right rotation. The mounting frame 32 is hinged on the top of the connecting seat 36 and can rotate in the front and rear direction relative to the connecting seat 36. An adjustment component 35 that drives the mounting frame 32 to rotate forward and backward relative to the connecting seat 36 is provided between the front end of the mounting frame 32 and the connecting seat 36. The upper end of the lifting arm 2 is connected to the connecting seat 36 to drive the support plate component 3 to be lifted and lowered relative to the base 1.

[0025] The mounting frame 32 is a quadrilateral frame structure, and has a longitudinal connecting shaft 34 extending forward and backward in the mounting frame 32. The lower surface of the top plate 31 has two connecting blocks distributed forward and backward, and both connecting blocks have through holes for the longitudinal connecting shaft 34 to pass through. Therefore, the top plate 31 is connected to the longitudinal connecting shaft 34 through the connecting blocks to achieve the left and right rotation function.

[0026] The lifting support column 33 is a screw rod with a connecting sleeve on the outer side wall of the mounting frame. A plurality of lifting support columns 33 are vertically threadedly engaged with the corresponding connecting sleeves of the mounting frame 32 and are distributed on the left and right sides of the longitudinal connecting shaft 34 to support the top plate 31. When the lifting support column 33 rotates, the height of the lifting support column 33 can be adjusted to adapt to the height of the left and right sides of the top plate 31 after rotation, and to support it so that the top plate 31 remains in a stable state.

[0027] There are four lifting support columns 33, which are evenly distributed on the left and right sides of the longitudinal connecting shaft 34. The two lifting support columns 33 on the same side are distributed front and back, and are connected to each other by a synchronous belt to achieve synchronous rotation and synchronous lifting of the two, which is convenient for operation and stable.

[0028] Limiting plates 311 are arranged at four vertex positions on the upper surface of the top plate 31, and fixing chains 312 are arranged between the limiting plates 311. Through the limiting plates 311 and the fixing chains 312, the engine can be stably limited on the top plate 31 for easy maintenance and transportation.

[0029] The connecting seat 36 includes two parallel triangular plates 361 and an upper connecting shaft 363 and a rear connecting shaft 362 disposed between the two triangular plates 361. The connecting seat 36 is hinged to the mounting frame 32 via the upper connecting shaft 363, which is located at the lower side of the longitudinal connecting shaft 34 and perpendicular to the longitudinal connecting shaft 34. The upper end of the lifting arm 2 is connected to the upper connecting shaft 363 and the rear connecting shaft 362.

[0030] The adjustment assembly 35 includes an adjustment screw 351, a screw shaft 352 and a screw top shaft 353. A rotating shaft frame 321 formed by two plates is provided at the front side of the mounting frame 32, and the screw shaft 352 is arranged on the rotating shaft frame 321 at the front side of the mounting frame 32 and can rotate; the screw top shaft 353 is installed at the front side of the connecting seat 36 and can rotate, that is, the screw top shaft 353, the upper connecting shaft 363 and the rear connecting shaft 362 are respectively located at the three top angles of the triangular plate 361; the adjustment screw 351 passes through the screw shaft 352 and the screw top shaft 353 at the same time, and is threadedly matched with the threaded hole on the screw shaft 352, and can rotate circumferentially with the screw top shaft 353 in the axial limit, so that after the adjustment screw 351 is rotated, the screw shaft 352 and the mounting frame 32 can be driven to rotate in the front and rear directions through the threaded matching of the adjustment screw 351 and the screw shaft 352.

[0031] The screw shaft 352 and the screw top shaft 353 are parallel to each other and extend transversely. The screw top shaft 353 has a through hole for the screw to pass through. The rear end of the adjusting screw 351 is a connecting section, on which a locking sleeve 354, a front plane thrust bearing 355, a rear plane thrust bearing 356 and a locking nut 357 are sequentially mounted from front to back. The screw top shaft 353 is located between the front plane thrust bearing 355 and the rear plane thrust bearing 356, so that the adjusting screw 351 and the screw top shaft 353 can achieve axial limit circumferential rotational cooperation.

[0032] The front end of the adjusting screw 351 is a connecting section with an external thread that matches with the threaded hole on the screw shaft 352. Therefore, when the adjusting screw 351 rotates, the screw shaft 352 can be driven close to or away from the screw top shaft 353 under the action of the thread matching force. The screw shaft 352 can rotate on the rotating shaft frame 321, and the screw top shaft 353 can rotate on the connecting seat 36 to adapt to the position change between the screw shaft 352 and the screw top shaft 353 when the adjusting screw 351 rotates.

[0033] The lifting arm 2 is of the prior art, and comprises a jack 23 , a lifting frame 21 , a short connecting rod 24 and a long connecting rod 22 .

[0034] The seat of the jack 23 is fixed on the base 1 by a bolt assembly, and the piston rod of the jack 23 faces backward and is connected to the oil pump push rod 25 extending laterally; there are two short connecting rods 24, the rear ends of the two short connecting rods 24 are hinged to the two ends of the oil pump push rod 25, and the front ends are hinged to the front lower end of the lifting frame 21, and the rear upper end of the lifting frame 21 is hinged to the upper connecting shaft 363. There are also two long connecting rods 22, and they are located on both sides of the lifting frame 21. The front lower ends of the two long connecting rods 22 are hinged to the base 1, and the rear upper ends are hinged to the rear connecting shaft 362. When the jack 23 drives the lifting frame 21 to move, the two long connecting rods 22 perform adaptive movements to lift or lower the pallet assembly 3.

[0035] During use, the left and right sides of the top plate 31 can be rotated up and down relative to the mounting frame 32, and the front and rear sides of the mounting frame 32 can be rotated up and down relative to the connecting seat 36. Therefore, the engine placed on the top plate 31 can be rotated up and down in four directions, front and back, left and right, to adjust the angle, so as to adjust the engine to the required angle, which is convenient for staff to inspect or transport.
