Abstract
The utility model discloses a car top guardrail with an overhaul platform, which comprises a guardrail body and a platform plate on a car, wherein the platform plate is connected with the guardrail body through a hinge, and the platform plate can turn over along the hinge; through the design of turning and drawing in the platform plate, the platform plate can be unfolded or drawn in as required without disassembly and assembly, and the use is more convenient and flexible.
Description
Technical Field
The utility model relates to an elevator technical field, especially a take sedan-chair top guardrail of retractable maintenance platform.
Background
According to the structural characteristics of common elevators, for example, the overhaul space of the car top with the tonnage of 630kg and below is less than 5.7.1.1b in GB7588-2003 Elevator manufacturing and installation safety Specification, "enough space should be arranged above the car, the size of the space is determined to be capable of accommodating a passenger not less than 0.50m × 0.60m × 0.80m, when any plane is placed downwards," the overhaul platform is generally arranged above the upper beam to ensure that elevator maintainers have enough and safe overhaul space.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a sedan-chair top guardrail of platform is overhauld in area. The utility model provides a technical scheme that its technical problem adopted is:
the car top guardrail with the maintenance platform comprises a guardrail body and a platform plate on a car, wherein the platform plate is connected with the guardrail body through a hinge, and the platform plate can be overturned along the hinge.
As a preferred option, the guardrail body is including the cross arm angle steel and the bottom sprag frame of downside, be provided with on the car and support the upper beam, the cross arm angle steel and the support upper beam of guardrail body are connected, the support upper beam of guardrail body with the car top is connected.
As a preferred option, a contact switch is distributed on the guardrail body.
As a preferred option, the platform plate is provided with fixing holes.
As a preferred option, a platform support angle steel is arranged at the position, close to the upper edge, of the side edge of the support upper beam. The utility model has the advantages that: through the design of turning and drawing in the platform plate, the platform plate can be unfolded or drawn in as required without disassembly and assembly, and the use is more convenient and flexible.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a perspective view of the present invention;
fig. 2 is a perspective view of the platform plate of the present invention in a folded state.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1, the car top guardrail with the maintenance platform comprises a guardrail body 1 on a car and a platform plate 2, wherein the platform plate 2 is connected with the guardrail body 1 through a hinge 3, and the platform plate 2 can be overturned along the hinge 3.
Referring to fig. 2, when the platform board 2 needs to be folded, the platform board 2 only needs to be folded in a turning manner, for example, when a lamp and a fan in a car are maintained, the platform board 2 needs to be folded if a circuit, a connector and the like are below the platform; when hoistway components, such as a machine-room-less main machine, a machine-room-less/machine-room-less guide rail, a guide shoe, a guide wheel and the like, need to be repaired, the platform board 2 is unfolded and laid flat.
And contact switches 7 are distributed on the guardrail body 1. The contact switch 7 must be equipped with two sets of contacts of normally open and normally closed, and the normally closed contact of the contact switch 7 of guardrail is established ties with the maintenance switch of sedan-chair top maintenance box, and normally open contact establishes ties with the switch common port that slows down of sedan-chair top maintenance box, and when the guardrail was opened, contact switch 7 action, the elevator is the maintenance state, shows that maintenance personal has done the guardrail and has repaired, and the elevator cuts off the safety circuit automatically, and any condition can not start the elevator. The contact switch 7 can be of many types, for example, as an alternative, the contact switch 7 can be a UKS switch. The position of the contact switch 7 may be dependent on the size, position of the platform board 2 or other parameters, requirements of the elevator.
The platform plate 2 is provided with a fixing hole 21, and the fixing hole 21 can be inserted with a bolt 22, so that the platform plate 2 can be conveniently and auxiliarily fixed when being unfolded and laid flat. When the elevator needs to be overhauled, the maintainers open all the guardrails and fix the guardrails by using bolts 22, and the guardrail can be slowly moved only by fixing the guardrail body 1 and the platform plate 2, so that the guardrails can protect the maintainers; after the overhaul is finished, the guard rails must be restored to a folded state, and the elevator can normally run.
Support 6 sides of upper beam and lean on the border position and be provided with platform support angle steel 8 for supplementary the supporting place flat back platform board 2, also can the supplementary fixed platform board 2 of trompil on the platform support angle steel 8.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
Practice proves that the height of the same top layer which meets the national standard specification can be reduced by using the folding guardrail
Left and right. The platform board 2 can be folded to a size limited by the size of the guide rails, the counterweight frame and the car
Preferably.
