Abstract

The invention discloses a telescopic wall leaning wheel which comprises a guide frame, a telescopic rod and a contact wheel, wherein the guide frame is provided with the guide wheel and a ratchet wheel, the telescopic rod is arranged in the guide frame in a penetrating mode and is limited and guided by the guide wheel, a rack is arranged on the telescopic rod along the length direction and is in matched transmission with the ratchet wheel, an anti-backward pawl acting on the ratchet wheel is arranged on one side of the ratchet wheel, and the contact wheel is installed at the outer end portion of the telescopic rod. The telescopic wall leaning wheel is limited by the guide wheel and enables the contact wheel to stretch and retract through the ratchet wheel transmission rack, stepless adjustment of the telescopic distance can be achieved, limitation of positioning holes and the like is avoided, the telescopic wall leaning wheel is better adapted to the concave vertical face, the stability of the platform is convenient to improve, the contact wheel can be locked after stretching out in place by the aid of the anti-falling pawl, a positioning structure does not need to be additionally arranged, unlocking operation is simple, use is convenient, and cost is low.

Description

Telescopic wall leaning wheel

Technical Field

The invention relates to the technical field of construction machinery, in particular to a telescopic wall leaning wheel.

Background

When working at high altitude, in order to ensure the safety of personnel, a safe and stable working platform is needed, which is commonly a hanging basket, the hanging basket generally comprises a suspension mechanism, a rail climbing device, a basket body and a safety system, the basket body can horizontally walk and vertically move along the rail, and the personnel can reach each vertical face of a building, and the hanging basket is mainly applied to cleaning, maintenance and other operations of ships, buildings or external windows and external walls of the buildings.

In order to improve the stability of the basket body, a wall leaning mechanism which enables the hanging basket to be always leaned against the vertical face of a building needs to be arranged, and the hanging basket is realized by arranging a wall leaning wheel at present. However, the surface of the outer wall of the building is not a plane, a plurality of the outer wall are provided with a certain concave vertical surface, the traditional wall leaning wheel is fixed on the basket body of the hanging basket, the distance cannot be adjusted, the hanging basket cannot adapt to the building with a certain concave-convex surface, or the adjustment operation is inconvenient, and the risk of high-altitude operation is increased.

Disclosure of Invention

Based on the problems, the invention aims to provide a telescopic wall leaning wheel, which improves the safety, the stability and the adjustment convenience of a lifting operation platform.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a flexible wall wheel that leans on, its includes leading truck, telescopic link and contact wheel, is provided with leading wheel and ratchet on the leading truck, and the telescopic link is worn to locate in the leading truck to by the spacing direction of leading wheel, be provided with the rack along length direction on the telescopic link, rack and ratchet cooperation transmission, one side of ratchet is provided with the anti-backtracking pawl that acts on the ratchet, and the contact wheel is installed in the outer tip of telescopic link.

Particularly, the anti-reverse pawl is rotatably arranged on the guide frame, and when the anti-reverse pawl releases the ratchet wheel, the telescopic rod and the contact wheel are freely withdrawn.

In particular, the anti-backup pawl is located above the ratchet wheel and is buckled on the ratchet wheel under the action of gravity.

Particularly, the guide wheel is divided into an upper guide wheel and a lower guide wheel, and the upper guide wheel and the lower guide wheel are vertically arranged at intervals and are respectively in rolling contact with the upper surface and the lower surface of the telescopic rod.

In conclusion, the telescopic wall-against wheel has the advantages that the telescopic wall-against wheel is limited by the guide wheel and the contact wheel can stretch and retract through the ratchet wheel transmission rack, the telescopic distance can be adjusted steplessly, the limit of a positioning hole and the like is avoided, the telescopic wall-against wheel is better matched with a concave vertical surface, the stability of a platform is improved conveniently, the anti-falling pawl can lock the contact wheel after the contact wheel extends in place, a positioning structure is not required to be additionally arranged, the unlocking operation is simple, the use is convenient, and the cost is low.

Drawings

Fig. 1 is a schematic structural view of a retractable wall wheel according to an embodiment of the present invention.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar parts throughout or parts having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediary, a connection between two elements, or an interaction between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the description of the present invention, unless otherwise expressly specified or limited, the first feature "on" or "under" the second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but with another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1, the preferred embodiment provides a retractable wall wheel, which includes a guide frame 1, a retractable rod 2 and a contact wheel 3.

Be provided with leading wheel and ratchet 4 on the leading truck 1, during leading truck 1 was worn to locate by telescopic link 2 to by the spacing direction of leading wheel, be provided with rack 5 along length direction on telescopic link 2, rack 5 and ratchet 4 cooperation transmission, one side of ratchet 4 is provided with the anti-backtracking pawl 6 that acts on ratchet 4, and contact wheel 3 installs in the outer tip of telescopic link 2.
