Description

Technical Field

[0001] This utility model relates to the field of elevator component manufacturing equipment technology, specifically to an elevator component assembly workbench. Background Technology

[0002] Elevator components, especially parts of the elevator car, are assembled on an assembly line. Workers need to remove the components from the assembly line and transfer them to an assembly workbench for assembly. Because some components are quite heavy, removing them from the assembly line is time-consuming and labor-intensive, sometimes requiring tools. Therefore, a multi-station independent continuous assembly workbench, authorized by patent publication number CN106241262B on August 7, 2018, has been developed. This workbench includes an assembly line support, horizontal guide wheels on both sides of the upper part of the support, a drive wheel frame in the middle with drive wheels mounted on it, and several worktables on the support. The bottom of each worktable engages with the drive wheels and horizontal guide wheels. Several workstations are located on the sides of the support; each workstation includes a workstation support with a longitudinal guide wheel frame on it, and several longitudinal guide wheels that engage with the worktables. In this invention, the items to be assembled are placed on a workbench. Upon reaching their workstation, the assembler pulls the workbench onto its corresponding support and performs the assembly at that station. After assembly, the workbench is pushed back onto the assembly line support. This invention utilizes a sliding mechanism, effectively saving physical effort. The sliding process avoids hard collisions, preventing damage to the items and the assembly line.

[0003] However, the guide wheel frame on the workstation support of the existing technology still supports the workbench during assembly. For some parts of the elevator car, the assembly needs to be carried out on a stable and level plane, otherwise it will affect the quality of the finished product after assembly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is:

[0005] I. An elevator component assembly workbench is provided, which can switch between assembly mode and moving mode, providing a stable and level working plane while saving time and effort in feeding components into or sending assembled finished products out of the workbench.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an elevator component assembly workbench, comprising an assembly platform, wherein at least two lifting slots are provided on the assembly platform, and a lifting plate with several rollers is provided on the assembly platform, wherein the position of the lifting plate corresponds to the position of the lifting slots, and a driving device is also provided on the assembly platform, wherein the output end of the driving device is connected to the lifting plate.

[0007] This solution uses a drive unit to move the lifting platform, enabling switching between assembly and movement modes. When the drive unit lowers the lifting platform into or below the lifting slot, the worktable enters assembly mode, its stable and flat surface serving as a working plane for assembling elevator components. When the drive unit raises the lifting platform, passing through the lifting slot and raising the rollers above the worktable's surface, the rollers act as support points for the elevator components, and the worktable enters movement mode, allowing the elevator components to easily enter and exit the assembly platform.

[0008] Optionally, both ends of the lifting plate are rotatably connected to a swing arm, and the end of the swing arm away from the lifting plate is rotatably connected to the assembly platform.

[0009] The design of the swing arm provides a stable motion path for the lifting plate, thus offering a wider range of options for the design of the drive device, rather than being limited to a design scheme that directly drives the lifting plate to move up and down.

[0010] Optionally, the driving device includes a driving pressure cylinder and a connecting block. The fixed end of the driving pressure cylinder is rotatably connected to the assembly platform, the output end of the driving pressure cylinder is rotatably connected to the connecting block, and the connecting block is rotatably connected to the lifting plate.

[0011] Specifically, the driving pressure cylinder can be designed on the support leg of the assembly platform, which can play its due role while saving installation space. Furthermore, by designing the operation button on the support leg of the assembly platform, the distance between the operation button controlling the driving pressure cylinder and the pressure cylinder can be shortened.

[0012] Optionally, the two lifting slots are parallel to each other.

[0013] Optionally, the rolling directions of the rollers are consistent.

[0014] The beneficial technical effects of this utility model are: this solution achieves the switching between assembly mode and movement mode by driving the lifting plate through the driving device. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Reference Figure 1-4 As shown, an elevator component assembly workbench includes an assembly platform 1, a lifting plate 2, a swing arm 3, and a drive device. The assembly platform 1 has two lifting slots 4. The lifting plate 2 is rotatably connected to the swing arms 3 at both ends and installed below the assembly platform 1. The position of the lifting plate 2 corresponds to the position of the lifting slots 4, allowing the lifting plate 2 to move up and down within the lifting slots 4. Each lifting plate 2 has eight rollers 5 arranged equidistantly, and the rolling direction of the rollers 5 is consistent with the movement direction of the elevator component entering and exiting the assembly platform 1.

[0022] The driving device specifically includes a driving pressure cylinder 6 and a connecting block 7. The fixed end of the driving pressure cylinder 6 is rotatably connected to the assembly platform 1, and the output end of the driving pressure cylinder 6 is rotatably connected to the connecting block 7. The connecting block 7 is connected to the lifting plate 2.

[0023] Eight extension rods 10 of the same size are rotatably connected to both sides of the assembly platform 1. When the size of the elevator component to be assembled is too large, the effective working area of ​​the workbench can be increased by rotating the extension rods 10 to expand it.

[0024] In this embodiment, the lifting plate 2 is driven by a drive device to switch between assembly mode and movement mode. In use, when the drive device drives the lifting plate 2 to descend into or below the lifting groove 4, the worktable enters the assembly mode, and its stable and flat working surface can serve as the working plane for assembling elevator components. When the drive device drives the lifting plate 2 to rise through the lifting groove 4 and makes the roller 5 higher than the upper surface of the worktable, the roller 5 serves as a support point for the elevator components, and the worktable enters the movement mode, allowing the elevator components to easily enter and exit the assembly platform 1.

[0025] As a further optional optimization of the above embodiment, a locking block 8 can be added to one end of the lifting plate 2 in the direction of movement when it rises, and a locking groove 9 is provided at the position corresponding to the locking block 8 in the lifting groove 4. The upper surface of the locking block 8 is flat, and the lower surface is curved, with the curvature of the curved surface consistent with the curvature of the arc trajectory of the lifting plate 2 when it rises. When the lifting plate 2 rises to a certain height, the locking block 8 engages with the locking groove 9, at which time the locking block 8 can assist in the positioning of the lifting plate 2 to a certain extent.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
