Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage equipment technology, and in particular to a lifting and following step channel for a lifting stage. Background Technology
[0002] The liftable stage used for performances plays an important role in the performance effect.
[0003] In common lifting stages, the follow-up step units used for aisles cannot maintain the aisle function continuously during the lifting process. They have poor horizontal stability and create large gaps between lifting stages, requiring additional steps to connect and ensure safe passage. Furthermore, the existing structure is relatively complex and requires automated control to achieve electrical linkage control between several steps, thereby reducing the hardware cost of control. Utility Model Content
[0004] To address the above requirements, this utility model provides a lifting and following step passage for a lifting stage. The passage can maintain its function continuously during the lifting process, and each following step unit can always maintain horizontal stability. The gaps between each step unit and between the step unit and the stage on both sides are small, eliminating the need for additional support platforms to ensure safe passage.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A lifting and following step channel for a lifting stage includes a first stage and a second stage with a certain distance between them. A lifting main beam and a certain number of step units arranged in sequence are arranged between the first stage and the second stage. A first hinge seat is provided on one side of the first stage, and a second fixed seat is provided on one side of the second stage. The second fixed seat is provided with a fixed seat support wheel and a fixed seat vertical guide rail. The lifting main beam has a support groove along its length. One end of the lifting main beam is hinged to the first hinge seat, and the other end is rolledly connected to the fixed seat support wheel through the support groove. Each step unit includes a step steel frame. The top of the step steel frame is a step. The step steel frame is provided with a step support wheel and step lifting retaining wheels and step vertical guide rails arranged in a front-to-back manner. The step lifting retaining wheel of the rear step unit is rolledly connected to the step vertical guide rail of the front step unit, and the step lifting retaining wheel of the foremost step unit is rolledly connected to the fixed seat vertical guide rail of the second fixed seat. All the step units are mounted on the lifting main beam via step support wheels and are connected in sequence via step lifting retaining wheels and step vertical guide rails / fixed seat vertical guide rails. During the raising or lowering of the second stage: the lifting main beam rotates along the first hinge seat, the fixed seat support wheel and the step support wheel roll along the support groove of the lifting main beam, and the step lifting retaining wheel rolls along the step vertical guide rails / fixed seat vertical guide rails. The step horizontal height of the step unit changes, but the distance between the step units remains unchanged.
[0007] Preferably, the vertical guide rail of the fixed seat and the vertical guide rail of the step are U-shaped, and the step lifting retaining wheel is embedded in the U-shaped structure to guide and limit the movement to prevent it from falling off.
[0008] Preferably, the number of the lifting main beams is two and they are arranged symmetrically from left to right, and the number of the first hinge seat, the fixed seat support wheel and the step support wheel are two and they are arranged symmetrically from left to right.
[0009] Preferably, the number of the step vertical guide rail and the number of the fixed seat vertical guide rail are two, and they are arranged symmetrically from left to right. Correspondingly, the number of the step lifting and holding wheels is two, and they are arranged symmetrically from left to right, thereby improving the stability of the step unit.
[0010] Preferably, the step lifting and retaining wheels are two in number and arranged symmetrically in the upper and lower positions to improve the stability of the step unit.
[0011] Preferably, the number of the step vertical guide rail and the number of the fixed seat vertical guide rail are two and arranged symmetrically from left to right, and the number of the step lifting and holding wheels is four and arranged symmetrically from top to bottom and from left to right, which greatly improves the stability of the step unit.
[0012] Preferably, the step support wheel and the step lifting and retaining wheel are not on the same vertical center plane, and one step support wheel and two step lifting and retaining wheels are triangularly distributed to improve the stability of the step unit.
[0013] The advantages of this utility model are: 1. During the lifting and lowering process of the stage, the function of the passage can be maintained continuously. Each follow-up step unit can always maintain horizontal stability. The gaps between each step unit and between the step unit and the stage on both sides are small, and no additional support platform is needed to ensure the safety of passage walking.
[0014] 2. The structure is simple and the function is reliable. It can use a single power source to realize the synchronous linkage between several steps, so that a walkable passage can be formed when the stage on both sides is at any height and safe walking is possible. It does not require complex automated control to realize the electrical linkage control between several steps, thus reducing the hardware cost of control.
[0015] 3. Rolling friction between all moving parts reduces resistance, saves energy and is environmentally friendly. It is easy to maintain, not easy to wear, has a long service life, and is not easy to jam during the lifting process, making lifting smoother. Attached Figure Description
