Abstract
The utility model discloses a home use elevator protection device for banket, characteristics are including installing the infrared sensor in elevator car bottom, install the main control unit at elevator car top, electric telescopic handle and lifting rod and be located the safety tongs on the elevator guide rail, infrared sensor passes through electric signal connection with main control unit, main control unit passes through electric signal connection with electric telescopic handle, when infrared sensor senses the foreign matter, electric telescopic handle shrink return adsorbs with the one end of lifting rod and is connected, the other end of lifting rod carries the clamp block of drawing safety tongs, infrared sensor is the infrared switch of a pair of correlation formula, the advantage is that the size is smaller and more exquisite, the reaction is more sensitive and the security is higher.
Description
Technical Field
The utility model belongs to the home use elevator field especially relates to a home use elevator protection device for banket.
Background
The elevator toe guard is generally installed on sills of halls and car doors, when the position of the car ground is higher than the landing ground, a gap is generated between the car and the landing sill, the gap can enable passengers to step into a shaft way, in order to avoid the possibility of personal injury, the related clauses in GB7588-2003 stipulate that the toe guard should be installed under each car sill of the elevator, the width of the toe guard should be equal to the whole net width of the corresponding landing entrance, and the vertical protection height of the toe guard should not be less than 0.75m, but the pit spacing of many buildings at present is smaller, so that the requirement of the existing buildings for smaller pit spacing can not be met if the toe guard is designed according to the related clause in GB 7588-2003.
When the traditional household elevator is in actual use, the mechanical baffle structure is adopted to prevent the feet of passengers from being clamped or injured due to the misoperation of the elevator car. However, when the home elevator adopts the mechanical baffle structure, according to the national home elevator manufacture and the specification (GB/T21739-2008), the civil engineering of the owner must meet the requirement that the pit size is greater than the minimum safe distance (the distance between the lowest point of the car and the highest point of the pit must be greater than 0.3 m, and when the mechanical baffle structure is adopted, the pit depth is generally required to be not less than 1.1 m). Most of the owners do not have this condition at all before ordering (using) the home elevators, or the civil works cannot satisfy this condition at all. Many owners do not need to violate the standard in order to use the home elevator, install forcibly and use the elevator that does not conform to the national standard, bring the potential safety hazard for the use of elevator.
Disclosure of Invention
The utility model aims to solve the technical problem that a home elevator protection device for banket that size is smaller and exquisite, and the reaction is more sensitive and the security is higher is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a domestic elevator protection device for banket, is including installing the infrared sensor in elevator car bottom, installing main control unit, electric telescopic handle and the lifting rod at elevator car top and being located the safety tongs on the elevator guide rail, infrared sensor with main control unit pass through electric signal connection, main control unit with electric telescopic handle pass through electric signal connection, work as infrared sensor sense when the foreign matter, electric telescopic handle shrink return with the one end of lifting rod adsorb and connect, the other end of lifting rod carry and draw the tong piece of safety tongs.
The infrared sensor is a pair of opposite infrared switches.
Compared with the prior art, the utility model has the advantages of:
1. adopt the monitoring method who whether has foreign matters such as passenger's foot to get into when installing in the infrared sensor of car bottom as the car abnormal movement, replace traditional mechanical baffle structure, the utility model discloses a non-contact monitoring's method, whole size is smaller and more exquisite, and the reaction is more sensitive, and reduction that can be very big is to the minimum pit dimensional requirement that accords with national home use elevator and make and installation standard.
2. The emergency stop device moves the elevator safety gear through the electric telescopic rod and the lifting rod to replace the traditional method of clamping the steel wire rope by the rope clamping device to prevent the car from moving, and the emergency stop device has higher practicability and safety.
To sum up, the utility model relates to a home use elevator protection device for banket, adopt main control unit to detect and install in the infrared sensor of car lower part, certain floor is berthhed at the elevator, and open the door when waiting for the passenger to get on or off the elevator, when the abnormal conditions appear, when leading to the car unusual removal, for example the band-type brake of hauler breaks down, can't guarantee to take place to remove under the normal stop state of elevator, or control system breaks down, when leading to taking place to remove abnormal conditions such as under the normal stop state of elevator, if there is foreign matter such as passenger's foot below the car sill to enter, infrared sensor carries main control unit with the signal, main control unit control electric telescopic handle moves, the action of lifting rod pulling safety tongs realizes emergency stop, guarantee that the car does not take place to reciprocate, thereby avoid the clamp foot occurence of failure.
Drawings
Fig. 1 is a schematic structural view of the home elevator protection device for protecting feet of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
A household elevator protection device for protecting feet comprises an infrared sensor 2 (manufacturer: ohm dragon; model: E3Z-T61A) arranged at the bottom of an elevator car 1, a main controller 3 (manufacturer: Ningbo bonded area Kexun electric appliances Limited; model: CCP 02) arranged at the top of the elevator car 1, an electric telescopic rod 4 (manufacturer: Wenzhou Heifeng electric appliances; model: HF-TGA), a lifting rod 5 and a safety clamp 7 arranged on an elevator guide rail 6, wherein the infrared sensor 2 is connected with the main controller 3 through electric signals, the main controller 3 is connected with the electric telescopic rod 4 through electric signals, when the infrared sensor 2 senses foreign matters, the electric telescopic rod 4 retracts and is connected with one end of the lifting rod 5 in an adsorption mode, and the other end of the lifting rod 5 pulls a clamp block of the safety clamp 7. The infrared sensor 2 is a pair of opposed infrared switches.
Stop certain floor at the elevator, and open the door and wait for when the passenger gets on or off the elevator, when the abnormal conditions appearing, when leading to 1 unusual movements of car, for example the band-type brake of hauler breaks down, can't guarantee to take place to remove under the normal stop state of elevator, or control system breaks down, when leading to taking place to remove under the normal stop state of elevator and so on the abnormal conditions, if when having foreign matters such as passenger's foot to enter in below the car sill 8, infrared sensor 2 carries main control unit 3 with the signal, main control unit 3 control electric telescopic handle 4 action, the action of 5 pulling safety tongs 7 actions of lifting rod realizes emergency stop, guarantee that 1 does not take place to reciprocate of car, thereby avoid because the clamp foot occurence of failure that elevator arouses.
The above embodiments are further illustrative of the present invention, but the scope of the present invention is subject to the claims.
