The principle and effect of this basic scheme lie in:
1. compared with the prior art, this device simple structure, think about ingenious, when the well wall of elevator is more than 0.3m from elevator car top outside edge horizontal direction free distance, the guardrail should be installed on the sedan-chair top, workman's nonstandard operation action probably leads to the fixed circumstances that appears not hard up of sedan-chair top guardrail, this device has set up position sensor, utilize position sensor to monitor the position of guardrail structure, in case the change of guardrail structure's position, alarm lamp will light, send the warning luminous to this anomaly, it is unusual to wake up sedan-chair top staff elevator car top guardrail fixing.
2. Compared with the prior art, this device is equipped with position sensor, alarm lamp and switch board, and the design of three can not influence the use of guardrail structure, and the cabinet body design of switch board also can not influence staff's working position for this device convenient to use, less to staff's influence.
Further, the guardrail structure comprises a frame main body and a plurality of fixed frameworks arranged on the frame main body, and the bottom of the frame main body is detachably connected with the elevator car roof. The design of the frame main body and the fixed framework is adopted, so that the strength of the guardrail structure is improved.
Further, the frame body and the fixed skeleton are both solid structures. The strength of the guardrail structure is improved.
Further, the control cabinet comprises a singlechip and an input power supply, the position sensor detects an IO signal and inputs the IO signal to the singlechip, and the singlechip in the control cabinet outputs a pulse signal to the alarm lamp through a preset program. The lighting of the alarm lamp is realized.
Further, the model of the singlechip is an 80C51 singlechip.
Further, the alarm lamp is installed at the top of the frame body and is uniformly arranged at the top of the frame body. The alarm lamp is installed at the top of frame main part can make the alarm lamp possess good field of vision, makes things convenient for the staff to see to also can not influence the work of staff.
Further, the mounting position of the position sensor is close to the bottom of the frame body, and the transmitting end of the position sensor is aligned with the bottom of the frame body. The position of the object is detected by means of a position sensor, which means that the position sensor is referenced to or from a certain fixed point or position reference, and the position sensor then provides feedback of the position.
Furthermore, the frame main part one side fretwork is used for the staff business turn over, and fixed skeleton is cross structure rigid coupling on the frame main part. The working personnel can conveniently go in and out.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings that are needed in the description of the embodiments will be briefly introduced below, it being obvious that the drawings in the following description are only some embodiments of the present application, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 shows a schematic installation diagram of an alarm device suitable for monitoring abnormal states of a guardrail at the top of an elevator car according to an embodiment of the application.
Detailed Description
In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.
Reference numerals in the drawings of the specification include: elevator 1, position sensor 2, frame main part 3, fixed skeleton 4, switch board 5, alarm lamp 6.
Examples are shown in fig. 1:
the utility model provides an alarm device suitable for unusual control of elevator sedan-chair top guardrail fixed state, is including setting up the guardrail structure at elevator 1 sedan-chair top, including setting up a plurality of position sensor 2 on the guardrail structure and setting up the switch board 5 at elevator 1 sedan-chair top, the guardrail is structural to be equipped with the alarm lamp 6 that is connected with the switch board 5 electricity.
The guardrail structure comprises a frame main body 3 and a plurality of fixed frameworks 4 arranged on the frame main body 3, wherein the bottom of the frame main body 3 is detachably connected with the top of the elevator 1. Specifically, the screw connection adopts the design of frame main part 3 and fixed skeleton 4, improves the intensity of guardrail structure, and as shown in fig. 1, frame main part 3 one side fretwork is used for the staff business turn over, and fixed skeleton 4 is cross structure rigid coupling on frame main part 3. The working personnel can conveniently go in and out.
