Description
Technical Field
The utility model relates to an elevator safety maintenance field especially relates to a safety device for realizing guaranteeing well bottom maintenance space of shallow pit elevator.
Background
When some elevators are additionally installed in buildings or old buildings, which are already designed, the normal requirements of the elevators on the pit depth can not be met due to the structural limitation or the design limitation of the buildings. The GB 7588 plus 2003 elevator manufacturing and installation safety regulation makes relevant requirements on the pit depth of the elevator, and when the pit depth cannot meet the safety requirements of the maintainers, the GB/T28621 plus 2012 makes supplementary provisions on relevant terms in the new elevator manufacturing and installation safety regulation installed in the existing building: the elevator should be provided with devices etc. that guarantee a top floor safety space and a pit safety space.
However, existing safety devices require elevator service personnel to first enter the pit and then install the associated safety device. The elevator maintainer not only can have the potential safety hazard when passing in and out the pit, but also installs and dismantles the safety device and relies on the manpower of overhauing operating personnel, and it is very inconvenient to use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a safety device for realizing guaranteeing well bottom maintenance space of shallow pit elevator, fundamentally has solved above-mentioned problem. Not only protects the operation safety of maintenance personnel in the pit, but also is beneficial to obtaining smaller pit depth.
In order to achieve the above purpose, the utility model provides a following technical scheme: this portable stop device of elevator includes mounting bracket, the bracing piece of perpendicular to horizontal plane, and its technical essential is: the mounting bracket and the supporting rod are relatively parallel, an electric push rod and a pair of swing arms which are equal in length and parallel to each other are hinged between the mounting bracket and the supporting rod, the hinge point of the electric push rod on the mounting bracket is higher than the horizontal line where the hinge point of the upper swing arm is located, and the hinge point of the electric push rod on the supporting rod is lower than or located on the horizontal line where the hinge point of the lower swing arm is located.
The utility model has the advantages and positive effects that: the utility model is fixed at the designated position at the side or below the lift car when the elevator operates normally, and the normal operation of the elevator is not influenced; when the elevator protects maintenance personnel and opens bottom room door, through remote control electric putter, extend the bracing piece below the car automatically to overlap with car buffer vertical direction projection, can stop the car by machinery, guarantee elevator pit safety space, effectively reduce the potential safety hazard, easy operation uses manpower sparingly.
Drawings
The invention is further described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the utility model in the contracted state.
Fig. 2 is a schematic structural diagram of the working state of the present invention.
Description of reference numerals: 1 mounting bracket, 2 electric putter, 3 hinge pin, 4 swing arms, 5 bracing pieces, 6 pit ground.
Detailed Description
The specific structure of the present invention will be described in detail with reference to the accompanying drawings 1-2. The movable stopping device of the elevator comprises a supporting rod 5 which can play a role of supporting and stopping the elevator car and a mounting frame 1 for fixing the device. The mounting frame 1 is firmly and vertically fixed on a pit ground 6, the upper end surface and the lower end surface of the support rod 5 are both planes, two swing arms 4 are respectively arranged on two sides of the support rod 5, one end of each swing arm 4 is connected with the support rod 5 through a hinge shaft 3, and the swing arms 4 can rotate relative to the support rod 5; the other end of the swing arm 4 is connected with the mounting frame 1 through a hinge shaft 3, and the swing arm 4 can rotate relative to the mounting frame 1; one end of the electric push rod 2 is connected with the support rod 5 through the hinge shaft 3, the other end of the electric push rod is connected with the mounting frame 1 through the hinge shaft 3, and the electric push rod 2 can rotate relative to the support rod 5 and the mounting frame 1 respectively.
The extension and contraction of the electric putter 2 is controlled by the electrical commands of the elevator. The position of the supporting rod 5 is changed along with the automatic extension and contraction of the electric push rod 2; when the electric push rod 2 extends to the longest state, the lower end of the support rod 5 is in close contact with a well pit, and the support rod 5 is vertical to a pit ground 6; when the electric push rod 2 is shortened to the shortest state, the support rod 5 is abutted to the mounting frame 1, and the normal operation of the elevator is not influenced.
Before the elevator maintenance personnel enter the pit of the shaft to work, the door of the pit is opened, the electric push rod receives an extension instruction signal, the electric push rod 2 automatically extends to drive the support rod 5 to leave the mounting frame 1, the support rod 5 moves to the working position, the lower end of the support rod 5 is in close contact with the pit ground 6, the support rod 5 is perpendicular to the pit ground 6, the limit switch in the electric push rod 2 acts, and the electric push rod stops running and extends, as shown in fig. 2. The support bar 5 now overlaps the vertical projection of the buffer located at the bottom of the car. When the car accidentally moves downwards, the buffer device at the bottom of the car firstly collides with the upper end face of the support rod 5 to stop the car, so that the safety space of a pit at the lower part of the car is ensured, and maintainers are prevented from being crushed in the pit of the shaft.
When the elevator needs to recover to normal operation, the electric push rod 2 automatically shortens to drive the supporting rod 5 to be recovered from the working position, the supporting rod 5 moves to be close to the mounting frame 1, the limit switch in the electric push rod 2 acts, and the electric push rod stops running and shortens as shown in fig. 1. At the moment, the projection of the movable elevator stopping device and the projection of the elevator car in the vertical direction are not overlapped, and the operation of the elevator car is not influenced.
Preferably, an electric push rod is used to drive the support rod to move, and the electric push rod can be replaced by other driving devices including but not limited to a hydraulic cylinder, a pneumatic cylinder and the like.
Preferably, the buffer device is arranged at the bottom of the car, and the buffer device can also be arranged on the support rod.
It is to be emphasized that: the above is only the preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and all the technical matters of the present invention are any simple modifications, equivalent changes and modifications made to the above embodiments, and all still belong to the scope of the technical solution of the present invention, including and not limited to the changes in the form of replacing the electric push rod with other driving devices such as a hydraulic cylinder, a pneumatic cylinder, etc., and setting the damping device on the support rod, etc.
