Description

Cam positioning climbing frame

Technical Field

The invention relates to the field of buildings, in particular to a cam positioning climbing frame.

Background

When the guide rail is climbed and stops in construction, the conventional climbing frame needs to be positioned by means of matching of top bracing devices on a plurality of guide seats and guide rail anti-falling holes on the guide rail. The top support device is manually operated and attached to the anti-falling hole of the guide rail, only one guide seat provides vertical force to support the guide rail, the guide rail does not disperse the gravity of the guide rail to other guide seats, and the guide rail has inertia impact when falling to the top support. And because the guide rail anti-falling holes are arranged at a certain interval, the guide rail can not be stopped at any point, the stopping position (the stopping position refers to the position of the acting point for supporting the guide rail) can only be the position of the guide rail anti-falling holes, and the guide rail anti-falling holes cannot be stopped.

Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Exemplary embodiments of the invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It should be understood that the embodiments and specific features in the embodiments of the present invention are described in detail in the present application, but not limited to the present application, and the features in the embodiments and specific features in the embodiments of the present invention may be combined with each other without conflict.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, the cam-positioned climbing frame of the present embodiment includes a scaffold board, a connecting board, a turning board, a vertical rod, a protective screen frame, a connecting member, a power system, and a guide rail 1 and a plurality of guide seats 2 which are combined into a whole. The scaffold board, the connecting board, the turning board, the upright pole, the protective screen frame, the connecting member and the power system are the prior art, the arrangement of the invention is the same as the common structure, so the description is omitted, and the improvement point of the embodiment is mainly concentrated on the guide rail 1 and the guide seat 2.

Specifically, the guide rail 1 includes a first guide rail 11 and a second guide rail 12 which are arranged in parallel, the first guide rail 11 and the second guide rail 12 are integrally fixed in a T-shape, and a side portion of the second guide rail 4 is fixed to a central position of the first guide rail 11.

Referring to fig. 2, the guide base 2 includes a base body 21, a cam 22 and a torsion spring 23, wherein the base body 21 is slidably engaged with the guide rail 1. Specifically, the seat body 21 has a through channel, and the first guide rail 11 vertically penetrates through the channel. The cam 22 is fixed in the seat body 21 through a fixed shaft, the cam 22 faces the first guide rail 11, the first guide rail 11 is in contact with the outer surface of the cam 22 when passing through a channel, the torsion spring 23 provides torsion for the cam 22 to enable the cam 22 to be always in contact with the guide rail 1, and when the guide rail 1 descends, the cam 22 of all the guide seats 2 matched with the guide rail 1 is driven to jointly extrude the guide rail 1 until the guide rail is locked and cannot descend.

More specifically, referring to fig. 3, the torsion spring 23 is disposed in a groove on one side of the cam 22, which surrounds the center of the cam 22. The outer surface of the cam 22 forms a step 221, and the step 221 is a plane or a curved surface, and the curved surface includes various types of regular and irregular surfaces, which is not limited herein. The radial dimension of the outer surface of the cam 22 gradually decreases from the position of the step 221 to the first direction (counterclockwise direction indicated by the arrow in the figure), the cam 22 is driven to rotate along the first direction when the guide rail 1 descends, so that once the cam 22 rotates along the first direction, the surface position with larger radial dimension of the cam 22 is inevitably caused to contact with the first guide rail 11, so as the cam 22 rotates along the first direction, the cam 22 is more pressed against the first guide rail 11, the friction force between the cam 22 and the first guide rail 11 is larger, and if the friction force provided by the cams 22 of all the guide seats currently matched with the first guide rail 11 is enough to counteract the gravity of the guide rail 1, the guide rail 1 stops descending.

Preferably, in order to ensure the friction, the outer surface of the cam 22 is provided with a pattern.

In conclusion, the cam positioning climbing frame has the following beneficial effects: according to the invention, an additional top bracing device does not need to be manually arranged to support the guide rail, so that the top bracing device on the guide seat is omitted; the stop position of the guide rail is not limited, the guide rail can be stopped at any point for construction, the climbing frame descending cam starts to press the guide rail until the guide rail is pressed tightly due to the fact that the cam is always in contact with the guide rail, the flexible braking process is achieved, the guide rail drives the cams of all guide seats matched with the guide rail to be pressed against the guide rail when descending, and the guide rail is driven to be pressed against each guide seat matched with the guide rail by the aid of the weight of the guide rail, so that the defects are avoided.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
