Description

Technical Field

[0001] This application relates to the field of escalator step processing technology, and in particular to a drive device for step production and processing. Background Technology

[0002] Escalators are currently widely used in shopping malls, hospitals, and other places. They can replace stairs, reducing the physical burden on riders. In shopping malls, they can improve the shopping comfort of customers, while in hospitals, they can reduce the physical burden on patients. Therefore, escalators are now widely used.

[0003] Escalators consist of multiple steps and operate in a rotating manner. Each step is manufactured separately, and the structure of a single step is as follows: Figure 1 As shown, the system includes a support frame, a tread plate on the top of the support frame, a kick plate on the side wall, and a first hole for mounting the main wheel and a second hole for mounting the auxiliary wheel. By mounting the main wheel and auxiliary wheel on the support frame, the steps can achieve smooth rotational operation.

[0004] Since a single step includes a support frame, treads, kick plates, and other structures, after the overall mechanical processing is completed, further processing and dimensional inspection are required for surfaces such as treads and kick plates. Therefore, in actual operation, the steps need to undergo further processing. Figure 2 The different states (angles) shown are flipped. Because the steps are irregular structures, they cannot be stably placed on the worktable after being flipped to different states. At the same time, it is inconvenient to set up support blocks. In further processing or dimensional inspection, the unstable state of the steps affects the processing accuracy or inspection results. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a drive device for tiered production and processing, which can achieve the flipping of the tiers at any angle and maintain their stable state after flipping, facilitating further processing and inspection operations.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a drive device for step production and processing, wherein the step is composed of a pedal, a kick plate and a support frame, the support frame is provided with a first hole for installing the main wheel and a second hole for installing the auxiliary wheel, the drive device includes a worktable, on which support rods are symmetrically arranged, the height of the support rods is greater than the height of the step and the spacing between the support rods is greater than the width of the step, and a crossbar is detachably inserted through the top of the symmetrical support rods, the crossbar being inserted into the first hole or the second hole.

[0007] Preferably, the workbench is provided with a first slide rail, and the support rod on one side is slidably connected to the first slide rail in the direction of the support rod on the other side; a locking nut is sleeved on one end of the crossbar.

[0008] Preferably, a second slide rail of the same length as the workbench is provided at the center line of the symmetrical support rod. A slide table is provided on the second slide rail, and a telescopic rod is provided on the slide table. Locking screws that can be tightened onto the second slide rail are provided on the slide tables on both sides of the telescopic rod. The top of the telescopic rod is supported on the step outside the first hole or the second hole.

[0009] Preferably, the top end of the telescopic rod is hinged to a support plate that is flush with the step, and a locking hinge screw is provided at the hinge point of the support plate.

[0010] The beneficial effects of this application are: the drive device suspends the steps through the support rod and crossbar and restricts their rotation base point, ensuring that the steps do not shift after flipping, thereby improving the accuracy of further processing of the steps and the accuracy of dimensional detection.

[0011] By setting the first slide rail, the support rods on both sides can clamp the steps, thus limiting the current rotation state when rotating to any angle.

[0012] Furthermore, by setting up a second slide rail, slide table, telescopic rod and other structures, auxiliary support is provided for the steps outside the second hole position to overcome the deflection of the steps caused by gravity and external processing forces, thereby further improving the accuracy of processing and inspection operations.

[0025] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] See attached document Figures 3-12 The illustration shows a drive device for ladder manufacturing, wherein the ladder step 1 is composed of a pedal 11, a kick plate 12, and a support frame 13. The support frame 13 is provided with a first hole 1a for mounting the main wheel and a second hole 1b for mounting the auxiliary wheel. To facilitate the stability of the ladder step after overall machining and for further processing or dimensional inspection, this application provides a drive device, such as... Figure 3-5 As shown, the driving device includes a worktable 2, on which support rods 3 are symmetrically arranged. The height of the support rods 3 is greater than the height of the steps 1, and the spacing between the support rods 3 is greater than the width of the steps 1 (to facilitate the assembly of the steps between the support rods 3). A crossbar 4 is detachably inserted through the top of the symmetrical support rods 3, and the crossbar 4 passes through the first hole 1a or the second hole 1b. When using the driving device, the steps are transferred between the support rods 3, so that the first hole 1a or the second hole 1b (this application uses the second hole 1b as an example) corresponds to the hole on the support rod 3 through which the crossbar 4 passes. Then, the crossbar 4 is inserted into both the support rod 3 and the second hole 1b, so that the steps are suspended from the crossbar 4 on the upper part of the support rod 3 through the second hole 1b. Since the height of the support rod 3 is greater than the height of the step 1, the step 1 can rotate at different angles using the crossbar 4 as the rotation reference without contacting or interfering with the surface of the worktable 2. This allows the pedal 11, kick plate 12, etc., to be in a position that is easy to operate. Compared with the current method of flipping the step 1, this application can position the flipping base point of the step 1 through the drive device. After flipping, it can ensure that the step does not shift, thereby improving the accuracy of further processing of the step and the accuracy of dimensional detection.

[0027] To further define the state after step 1 is flipped, such as Figure 6-8As shown, the workbench 2 is equipped with a first slide rail 5, and one of the support rods 3 is slidably connected to the first slide rail 5 towards the other support rod 3; a locking nut 6 is sleeved on one end of the crossbar 4. After the step 1 is suspended on the crossbar 4 through the second hole 1b, the step is rotated to the desired operating state (angle), and then the locking nut 6 is rotated, causing one of the support rods 3 to slide closer to the other support rod 3 on the first slide rail 5. The support rods 3 on both sides then abut against the side wall of the step, clamping the step. This limits the state of the rotated step, facilitating smooth processing and inspection operations. When it is necessary to continue flipping the step 1, the locking nut 6 is loosened, the step 1 is flipped, and then locked again by the locking nut 6.

[0028] like Figure 9 As shown, after rotating step 1 to a certain state, due to gravity and the downward processing force, step 1 overcomes the clamping force of the support rods 3 on both sides, causing step 1 to flip downward at a certain angle, affecting processing and inspection. Therefore, to further solve this problem, as... Figure 10-11 As shown, a second slide rail 7 of the same length as the worktable 2 is provided at the center line of the symmetrical support rod 3. A slide table 8 is provided on the second slide rail 7, and a telescopic rod 9 is provided on the slide table 8. Locking screws 10 that can be tightened onto the second slide rail 7 are provided on the slide table 8 on both sides of the telescopic rod 9. The top of the telescopic rod 9 is supported on the step 1 outside the first hole 1a or the second hole 1b. In operation, after the step 1 is rotated and locked by the locking nut 6, the telescopic rod 9 and the slide table 8 are slid on the second slide rail 7 to the position outside the second hole 1b where the step 1 needs to be supported. Then, the locking screws 10 are rotated to tighten them onto the second slide rail 7, restricting the movement of the slide table 8 and the telescopic rod 9. Then, the telescopic rod 9 is extended (preferably a multi-stage screw structure) so that its top contacts the step 1, overcoming the downward gravity and processing forces of the step, and solving the influence of gravity and processing forces on the stability of the step.

[0029] Because step 1 is an irregular structure, it cannot be flat against the support frame 13 when the telescopic rod 9 contacts it. Therefore, to improve the support stability of step 1 when it rotates to different angles, such as... Figure 12As shown, the top of the telescopic rod 9 is hinged to a support plate 14 that is flush with the step 1, and a locking hinge screw 15 is provided at the hinge of the support plate 14. When the telescopic rod 9 adopts a multi-stage screw structure, the telescopic rod 9 needs to be rotated to achieve extension, while the support plate 14 rotates synchronously. When the support plate 14 is close to the support frame 13, it cannot be accurately rotated to a state parallel to the support frame because there is an angle. Therefore, during operation, the telescopic rod 9 is first rotated so that the support plate 14 is close to the position of the support frame 13 that needs support. The telescopic rod 9 is rotated to adjust the support plate 14 and the support frame 13 to be parallel to each other. Then, the slide table 8 is driven to slide on the second slide rail 7 so that the support plate 14 and the support frame 13 are in flat contact. Then, the hinge screw 15 and the locking screw 10 are locked to achieve flat support between the support plate 14 and the step 1. If a non-screw-structured telescopic rod (such as the internal structure of a telescopic cylinder) is selected, the telescopic rod 9 can be extended directly, so that the support plate 14 can be rotated by the hinge screw 15 and flat against the support on the step 1.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
