Description

Technical Field

[0001] The utility model relates to the field of supporting components of a walking platform of large-scale amusement equipment, in particular to a walking platform parking support mechanism and a walking platform. Background Art

[0002] At present, the walking platforms of large-scale amusement equipment on the market mostly use rubber-coated wheels for their walking wheels, and no walking platform support mechanism is designed. In actual operation, since the walking platform is stationary for a long time, the rubber-coated wheel is always under pressure at the same place and deformed, resulting in an irregular shape of the walking wheel. When the walking platform is started again, the walking platform will shake during walking, affecting the comfort of tourists and reducing the service life of the rubber-coated wheel. Most of the existing mechanisms with automatic control and jacking functions on the market currently use double-acting cylinders, which have large structural dimensions, a large number of mechanism control valves, complex control, and cannot be used for installation in narrow spaces. A small number of them use cylindrical tension springs, but the reset tension is small and the stability is poor. They are only used for small mechanisms and cannot be used as support mechanisms for large and heavy-loaded equipment.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a walking platform parking support mechanism and a walking platform, which have a compact structure and small size, can be installed in a narrow space, effectively support the walking platform, and thus solve the above-mentioned technical problems existing in the prior art.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A walking platform parking support mechanism, comprising:

[0007] Soft elastic support pad, flange, lifting ear seat, plunger cylinder, two sets of spring guide shaft assemblies, support and two springs; among them,

[0008] The soft elastic support pad is arranged under the flange and connected to the flange;

[0009] The piston rod of the plunger cylinder passes downward through the lifting ear seat and is connected to the flange;

[0010] The two groups of spring guide shaft assemblies are relatively arranged on both sides of the plunger cylinder, and the lower ends of the two groups of spring guide shaft assemblies are movably connected to the two sides of the lifting ear seat respectively;

[0011] The support is arranged on the upper ends of the two groups of spring guide shaft components from top to bottom, and is pressed on the bottom of the plunger cylinder from above by two springs.

[0012] A walking platform includes: a platform body and a parking support mechanism. The walking platform parking support mechanism described in the utility model is fixedly installed at the bottom of the platform body. It can support the ground through a soft elastic support pad when the walking platform is stationary, and can retract the soft elastic support pad when the walking platform is in a walking state.

[0013] Compared with the prior art, the walking platform parking support mechanism and the walking platform provided by the present invention have the following beneficial effects:

[0014] By using soft elastic support pads as support blocks, the system is suitable for use on uneven surfaces. A plunger cylinder provides lifting power, resulting in a compact structure and small size, suitable for installation in confined spaces. An external spring, combined with a spring guide shaft assembly, guides the cylinder piston rod to reset, facilitating easy maintenance. The spring guide shaft assembly is flexibly connected to the lifting lugs, preventing problems such as sticking in up and down movement caused by machining and installation errors. The addition of parking supports eliminates issues such as platform jitter and noise caused by the deformation of the travel wheels in the same position when the platform is not in use for extended periods.

[0036] Preferably, in the above parking support mechanism, the two sets of spring guide shaft assemblies have the same structure, both comprising:

After the parking support, the problems of platform walking jitter, noise, etc. caused by the long-term pressure and deformation of the walking wheels at the same position when the walking platform is in a static state for a long time when not in use are solved.

[0045] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the solution provided by the embodiments of the present invention will be described in detail with reference to specific embodiments below.

[0046] Example 1

[0047] like Figures 1 to 4As shown, this embodiment provides a walking platform parking support mechanism, which mainly includes: a polyurethane pad as a soft elastic support pad 1, a flange 2, a lifting ear seat 3, two groups of spring guide shaft assemblies (each group is composed of a self-lubricating rod end joint bearing 4 and a spring guide shaft 6), a plunger cylinder 5, a support 7 and a spring 8, and the spring 8 is a rectangular spring; wherein, the polyurethane pad as the soft elastic support pad 1 is threadedly connected to the flange 2, mainly serving as a support surface for the mechanism to contact the external surface, reducing the flatness requirement of the external surface, and the piston rod of the plunger cylinder 5 passes through the lifting ear seat 3 and is connected to the flange 2, mainly to provide a lifting thrust when parking; one end of the self-lubricating rod end joint bearing 4 is threadedly connected to the spring guide shaft 6, and the other end is hinged to the lifting ear seat 3 through a pin shaft, mainly used for automatic centering and absorbing manufacturing and installation errors. The main functions of the spring guide shaft 6 are, first, to serve as the central axis of the rectangular spring, and second, to play a guiding role in the lifting process and up and down movement. The support 7 can adopt an L-shaped structure and can be installed on the side of the walking platform. It is mainly used to fix the plunger cylinder and support the platform. The rectangular spring 8 is externally placed above the support 7 and is mainly used for the automatic reset of the piston rod of the plunger cylinder 5. In the initial state (non-working state), the spring can be slightly compressed by adjusting the nut on the spring guide shaft 6. At this time, the piston rod of the plunger cylinder 5 is in a non-extended state. When the walking platform is in a stationary state, the piston rod of the plunger cylinder 5 extends, driving the support 7 to move upward, thereby lifting the walking platform to a certain height. At the same time, the spring guide shaft 6 moves downward, causing the rectangular spring to be in a compressed state. When the walking platform needs to move, the plunger cylinder is depressurized, and at the same time, the rectangular spring returns to its initial state, driving the piston rod of the plunger cylinder 5 to reset.

[0048] In summary, in the parking support mechanism of the present invention, the plunger cylinder adopts a single-acting cylinder structure, which is installed in reverse. The piston rod end is externally threaded and passes through the lifting ear seat to connect with the flange. It has a compact structure and small size. One end of the spring guide shaft adopts an external thread and the other end adopts an internal thread. On the one hand, it serves as a rectangular spring spindle, and at the same time, it is connected to the flange through a self-lubricating rod end joint bearing and a pin hinge, which serves as a guide for up and down movement. A rectangular spring is adopted, which has the characteristics of large deformation capacity, high deformation strength and high fatigue resistance. It is externally placed on the upper end of the support and drives the plunger cylinder to move up and down by means of a compression spring. This support mechanism can reduce the wheel pressure of the walking platform when it is stationary, and avoid problems such as shaking of the walking platform and abnormal noise caused by long-term deformation of the walking wheel. By adopting a single-acting plunger cylinder to provide lifting power support and an external rectangular spring reset structure, the structure is compact, which effectively saves the installation space of the mechanism, reduces the number of hydraulic controls, simplifies the control, and saves the mechanism structure cost and electrical control cost.
