The lifting platform at the present stage is designed and manufactured according to the standard.
However, the lifting platform with the height of the compliant guard rail, which is designed and manufactured according to the standard, has problems in practical use, the whole height of the lifting platform transport vehicle can also be increased due to the fixed height of the guard rail, and the problem that the lifting platform cannot pass through or is inconvenient to pass through in the process of walking between different operation areas due to the limited height of the underground roadway of the mine is solved.
Therefore, a new lifting platform is needed, which can ensure that the lifting platform has a compliant guardrail protection height when working at high altitude in a specific area, and can smoothly pass through an underground roadway.
Disclosure of Invention
The utility model aims to disclose a foldable lifting platform for underground equipment, which can ensure that the height of a guardrail of the lifting platform meets the specification and can ensure that a working vehicle loaded with the lifting platform can smoothly run in an underground roadway.
In order to achieve the purpose, the application discloses a folding type lifting platform for underground equipment, which comprises a lifting platform, wherein each side of the lifting platform is provided with a fixed guardrail and a folding guardrail, the fixed guardrail and the folding guardrail are connected through hinges, and the folding guardrail can rotate between an opening position erected at the upper end of the fixed guardrail and a withdrawing position laid to one side of the fixed guardrail; the folding guardrail is characterized by further comprising a fixing piece, and when the folding guardrail is located at the opening position, the folding guardrail is fixed through the fixing piece.
Further, the mounting is including setting up bolt and pinhole in the key seat, the key seat set up in on the folding guardrail, the round pin lid set up in on the fixed guardrail.
Further, when the folding guardrail is in the opening position, the height of the fixed guardrail and the height of the folding guardrail are not less than 1100 mm.
Further, the height of the folding guardrail is smaller than that of the fixed guardrail.
Further, the height of the fixed guardrail is 750 mm.
The beneficial effects of the utility model include:
through the setting of folded cascade's jacking equipment's fixed guardrail and folding guardrail, realize the controllable of guardrail height, expand the guardrail to opening the position when carrying out safe operation, satisfy standard requirement, when the vehicle transportation, put down folding guardrail to withdrawing the position, can satisfy vehicle operation demand.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below. It is obvious that the drawings in the following description are some embodiments of the utility model, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.
Fig. 1 is a front view of the present invention.
Fig. 2 is a side view of the present invention.
FIG. 3 is an enlarged view of the latch position of the present invention.
In the figure, 1 is a lifting platform, 2 is a fixed guardrail, 3 is a folding guardrail, 4 is a hinge, 5 is a fixing piece, 51 is a pin seat, 52 is a bolt, 53 is a pin hole.
Detailed Description
The following detailed description of the present invention will be made in conjunction with the accompanying drawings, but the following examples are merely illustrative of preferred embodiments, which are provided to assist understanding of the present invention, and are not to be construed as limiting the present invention.
Reference will now be made in detail to 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 elements or elements having the same or similar function throughout.
The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected 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.
As shown in fig. 1-3, a collapsible lift platform for a downhole tool comprises a lift platform 1, which may be selected from various prior art lift platforms, such as a fixed hydraulic lift platform, for example, by those skilled in the art. Each side of the lifting platform is provided with a fixed guardrail 2 and a folding guardrail 3, the fixed guardrails and the folding guardrails are connected through hinges 4, and the folding guardrails can rotate between an opening position where the folding guardrails are vertically arranged at the upper ends of the fixed guardrails and a withdrawing position where the folding guardrails are placed to one side of the fixed guardrails; and a fixing part 5, which is used for fixing the folding guardrail when the folding guardrail is positioned at the opening position.
Preferably, the fixing member includes a plug 52 and a pin hole 53 which are disposed in a pin seat 51 which is disposed on the folding guardrail, and a pin cover which is disposed on the fixing guardrail.
When the guardrail is used, the folding guardrail part is lifted to the opening position, and the bolt is inserted into the pin hole, so that the safety height of the guardrail can be ensured. When the guardrail is not used, the bolt is pulled out from the pin hole, and the folding guardrail is put down, so that the height of the guardrail can be reduced.
