[0002] After the elevator car bottom is manually assembled, it needs to be sent to the paint room for painting. In this regard, the existing manufacturers' processing method is that the assemblers first assemble the elevator car bottom at the assembly station, and then hoist the elevator car bottom to the conveyor roller at the front end of the paint room by a crane after the elevator car bottom is assembled and formed, and the conveyor roller sends each elevator car bottom to the paint room in sequence for painting. However, this processing method requires the assemblers to hoist the elevator car bottom, which reduces the processing efficiency of the elevator car bottom and increases their workload. On the other hand, the elevator car bottom also has safety hazards and falling risks during the hoisting process; when designing the elevator car bottom, the manufacturer also needs to reserve a part for hoisting, which increases the structural complexity of the elevator car bottom.

[0003] Therefore, the existing assembly and painting methods for the elevator car bottom have the problems of low working efficiency and poor safety. Utility Model Content

[0014] (3) By connecting the second telescopic rod to the second lifting frame via the adjustment plate, the second telescopic rod can first lift the second lifting frame via the adjustment plate during the installation process, and in this state, the adjustment plate and the second lifting frame are separated from each other, so that the operator can adjust the lateral position of the second lifting frame according to the lateral position of the rolling frame, thereby ensuring the movement stability of the rolling frame; when the second lifting frame is positioned, the operator can weld the adjustment plate and the second lifting frame to each other, and then weld the second guide plate to the conveyor roller, thereby using the cooperation of the linear guide rail and the conveyor roller to perform lateral positioning of the second lifting frame, thereby preventing the second lifting frame from shifting later;

[0015] Therefore, the utility model can effectively improve the transportation efficiency and safety of the elevator car platform after assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] Embodiment. The assembly conveying platform for the car bottom is composed of Figure 1 As shown, it includes a conveyor roller 1, an assembly frame 2 is provided on one side of the conveyor roller 1, and operating tables 3 are provided on both sides of the assembly frame 2. The interval between the operating tables 3 on both sides is less than the width of the car bottom. A first lifting frame 4 is provided between the operating tables 3 on both sides. The lower end of the first lifting frame 4 is connected to the assembly frame 2 via a first telescopic rod 5, and a rolling frame 6 is placed on the upper end of the first lifting frame 4; a plurality of conveyor rollers 7 are arranged side by side in the middle of the conveyor roller 1, and a second lifting frame 8 is provided outside the conveyor roller 7. The second lifting frame 8 and the conveyor roller 7 are staggered with each other, and the lower end of the second lifting frame 8 is connected to the conveyor roller 1 via a second telescopic rod 9. Both the first telescopic rod 5 and the second telescopic rod 9 can be made of cylinders.

[0022] Tracks for supporting the rolling frame 6 are disposed on the tops of the first lifting frame 4 and the second lifting frame 8. The two ends of the bottom of the rolling frame 6 are placed on the tracks via rollers 10. The rollers 10 are engaged with the tracks after being placed.

[0023] A limit block for limiting the translation of the rolling frame 6 is provided at the end of the track.

[0024] The rolling direction of the rolling frame 6 and the conveying direction of the conveying roller 1 are arranged perpendicular to each other.

[0025] The assembly frame 2 is connected to a vertical first guide plate 11, and the lower end of the first lifting frame 4 is connected to the first guide plate 11 via a linear guide rail 12; the conveying roller 1 is connected to a vertical second guide plate 13, and the lower end of the second lifting frame 8 is connected to the second guide plate 13 via a linear guide rail 12.

[0026] The upper end of the second telescopic rod 9 is connected to the second lifting frame 8 via an adjustment plate 14, and a U-shaped groove is provided at the lower end of the adjustment plate 14. The rod head of the second telescopic rod 9 is buckled in the U-shaped groove via a fixing nut, and the upper end of the adjustment plate 14 and the bottom surface of the second lifting frame 8 are attached to each other and welded.

[0027] Working principle of the utility model: When installing the utility model, the operator first installs the first lifting frame 4 on the assembly frame 2, and places the rolling frame 6 on the track of the first lifting frame 4; then the rolling frame 6 is moved horizontally so that the rolling frame 6 moves to the second lifting frame 8, and the lateral position of the second lifting frame 8 on the conveying roller 1 is adjusted according to the position of the rolling frame 6, so that the rolling frame 6 can smoothly move back and forth between the first lifting frame 4 and the second lifting frame 8. During the position adjustment process of the second lifting frame 8, the adjustment plate 14 lifts the second lifting frame 8 from below and is in a state of separation from the second lifting frame 8, so that the second lifting frame 8 can freely adjust its lateral position. After the second lifting frame 8 is positioned, the operator welds the adjustment plate 14 and the second lifting frame 8 to each other, and at the same time welds the second guide plate 13 and the conveying roller 1 to each other, so as to limit the second lifting frame 8 by using the conveying roller 1 to avoid the deviation of the second lifting frame 2.

[0028] When the utility model is used, the operator first assembles the elevator car bottom on the operating table 3, and the rolling frame 6 is in a low position and separated from the elevator car bottom, so as not to affect the assembly operation. After the elevator car bottom is assembled, the first telescopic rod 5 is extended to drive the first lifting frame 4 to rise, and the rolling frame 6 is used to lift the elevator car bottom above, and then the operator pushes the rolling frame 6 loaded with the elevator car bottom horizontally to the second lifting frame 8, and the elevator car bottom is moved to the top of the conveying roller 7. After the rolling frame 6 is moved to the position, it is completely separated from the first lifting frame 4, and then the second telescopic rod 9 drives the second lifting frame 8 to descend, so that the elevator car bottom is placed on the conveying roller 7, that is, the transportation of the elevator car bottom is realized. After the elevator car bottom is transported to the position, the rolling frame 6 is pushed back to the first lifting frame 4 in a low position, so as to realize the resetting of the rolling frame 6.
