Description

Technical Field

[0001] The invention belongs to the technical field of tower cranes, and in particular relates to a dual-purpose driver's cab platform structure for a tower crane and an installation method thereof. Background Art

[0002] Currently, tower crane cab platforms typically utilize a square tube welded to the platform at one end, with the other end connected flush with the upper support via a pin. This type of cab platform structure is limited in functionality, and the welded contact surface is difficult to maintain and prone to deformation. The flush position of the cab platform with the upper support can significantly impact the operator's field of view, posing potential operational risks.

[0003] In the existing cab platform structure, such as Figure 1 As shown, Item 1 is the mounting pin, Item 2 is the cab platform structure, and Item 3 is the square tube connecting the cab platform structure and the upper support. It is connected to the cab platform structure 2 by welding, and the other end is connected to the ear plate of the upper support via the mounting pin 1. Although this cab platform structure can solve the problem of a wide field of vision, it will cause a certain degree of inconvenience when used in a narrow space.

[0004] like Figure 2 As shown, Item 1 is the mounting pin, Item 2 is the channel steel connecting the platform structure and the upper support, Item 3 is the cab platform structure, and Item 4 is the lug plate connecting the upper support and the platform structure. The cab platform structure 3 and the upper support are inserted into the lug plate 4 via the channel steel 2 and secured with four mounting pins 1. This type of cab platform structure, when installed, can affect the operator's field of view to varying degrees, reducing safety during operation. Summary of the Invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] like Figure 3 、 Figure 4 、 Figure 5 As shown, a dual-purpose driver's cab platform structure for a tower crane includes a driver's cab platform 1 and an upper support; a first connecting ear plate 6 is installed at the bottom of the driver's cab platform 1, and a second connecting ear plate 5 is installed on the upper support; in a working environment with a small space, when the first connecting ear plate 6 is directly connected to the second connecting ear plate 5, a flush structure of the driver's cab is realized, which not only solves the problem of limited working space but also does not affect normal use; when space permits, when the first connecting ear plate 6 is connected to the second connecting ear plate 6 through a connecting bracket, a sunken structure of the driver's cab is realized, which makes the tower crane's field of view wider and there is no obstruction in the field of vision.

[0036] The dual-purpose flat cab structure of the present invention not only solves the problem that the sunken cab platform may not be able to operate normally due to limited space, but also solves the potential problem that the conventional cab platform may interfere with the operator's field of vision to a certain extent; it is easy and quick to install, saving manpower and material resources.

[0037] Further solutions: Figure 4 As shown, the first connecting ear plate 6 is connected to the second connecting ear plate 5 by a mounting pin. The mounting pin realizes axial movement by inserting a split pin.

[0038] Further solutions: Figure 3 、 Figure 5 As shown, the first connecting lug 6 is connected to the third connecting lug 3 at one end of the connecting bracket via a mounting pin 2. The other end of the connecting bracket is inserted into the second connecting lug 5 of the upper support and connected via a mounting pin 4. Both the mounting pins 2 and 4 are axially movable by inserting a cotter pin.

[0039] Further solution: A step ladder is installed on the connecting bracket, and the walking transition between the driver's cab platform and the upper support is achieved through the step ladder.

[0040] A further solution is: a sleeve is provided on the connecting bracket, the bottom of the safety guardrail is inserted into the sleeve, and the two are fixed together by bolts.

[0041] like Figure 3 、 Figure 4 、 Figure 5 As shown, the present invention also discloses a method for installing a dual-purpose cab platform for a tower crane, the specific method being:

[0042] If space permits, the first connecting ear plate 6 of the driver's cab platform 1 is fixedly connected to the third connecting ear plate 3 at one end of the connecting bracket by installing the pin 2. The other end of the connecting bracket is inserted into the second connecting ear plate 5 of the upper support and fixedly connected by installing the pin 4, thereby realizing a sunken structure of the driver's cab, making the operator's field of view wider and unobstructed within the visual range.

[0043] In a working environment with limited space, the connecting bracket is removed and the driver's cab platform 1 is directly connected to the upper support, that is, the first connecting ear plate 6 on the driver's cab platform 1 and the second connecting ear plate 5 of the upper support are connected by installing a pin to achieve a flush structure, which not only solves the problem of limited working space but also does not affect normal use.

[0044] A further solution is to install a step ladder on the connecting bracket to achieve a walking transition between the cab platform and the upper support. A sleeve is provided on the connecting bracket, and the bottom of the safety guardrail is inserted into the sleeve, and the two are fixed together by bolts.

[0045] From the above, it can be seen that the dual-purpose cab platform structure has one platform with two uses, high availability, and greatly improved safety performance; it saves space during transportation and is convenient for transportation; it is simple to process and manufacture, and the pin connection is convenient for installation and disassembly, and the installation is quick, which improves the installation efficiency; the dual-purpose cab platform structure is suitable for more occasions. When space is limited, the connecting bracket can be removed to restore the original structure for normal use. When there is sufficient space, it can be changed to a sunken type to improve safety; the platform is fixed by the pin, which is more stable.

[0046] In the description provided herein, numerous specific details are described. However, it is understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques are not shown in detail so as not to obscure the understanding of this description.

For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.

[0048] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention.
