Description
Technical Field
The utility model relates to an elevator technical field, concretely relates to elevator prevents device down.
Background
Along with the higher living standard of people, the household elevator enters the life of people. In order to ensure the safe and long-term operation of the elevator, the maintenance of tension pulleys, buffers and the like in a pit is indispensable. According to the safety regulation 5.7.3.3 for manufacturing and installing an elevator of GB 7588 and 2003, the minimum pit space can accommodate a cuboid (which can face downwards arbitrarily) with the size of 0.50m multiplied by 0.60m multiplied by 1.0m, namely, the clearance distance between the pit bottom and the lowest part of the elevator car is not less than 0.5 m. However, due to the limitation of building structures, the number of elevators with pit heights not meeting national standard requirements is small, so that potential safety hazards are buried when maintainers operate in the pits. At present, most devices with connecting rod structures on the market protect pit personnel from being extruded when a car descends suddenly, the structure is complex, the parts connected by bolts of the devices are required to be checked frequently, and inconvenience is increased in use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of above prior art existence, provide a down stop device of elevator, this product simple structure, installation are direct, the position is adjustable, can prevent effectively that the elevator is down, guarantee pit maintainer's personal safety.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a descending prevention device of elevator, includes installation department and extension portion, the installation department side is equipped with first draw-in groove, the installation department upper end is equipped with the second draw-in groove, the extension portion lower extreme is equipped with logical groove of U type and L type.
Preferably, the two sides of the first clamping groove are respectively a first mounting block and a second mounting block of the mounting part, and the lower end of the second mounting block is longer than the first mounting block. The device can be prevented from falling off.
Preferably, a round angle is formed in the first clamping groove. The concentrated stress can be effectively reduced.
The utility model also provides a prevent device complex guide rail down with the elevator, be equipped with a plurality ofly on the guide rail with installation department complex mounting hole.
Preferably, the area of the mounting hole is larger than the first mounting block and smaller than the second mounting block.
Preferably, the distance between every two adjacent mounting holes is smaller than the width of the second clamping groove.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
1. the utility model discloses simple structure, the installation is direct, low in manufacturing cost.
2. The utility model discloses, the mounting method is simple, need not the inspection maintenance.
3. The utility model discloses an adjustable position, maintainer can adjust the position of mechanical prevention device wantonly according to the needs of oneself, reserves bigger safety inspection space for oneself.

Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
As shown in fig. 1, the elevator descending prevention device comprises an installation part and an extension part, wherein a first clamping groove is formed in the side edge of the installation part, a second clamping groove is formed in the upper end of the installation part, and a U-shaped through groove and an L-shaped through groove are formed in the lower end of the extension part.
The two sides of the first clamping groove are respectively a first mounting block and a second mounting block of the mounting part, and the lower end of the second mounting block is longer than the first mounting block. The device can be prevented from falling off.
A fillet is formed in the first clamping groove in a chamfering mode. The concentrated stress can be effectively reduced.
As shown in fig. 2, a guide rail is coupled to an elevator descending prevention apparatus, and a plurality of mounting holes are formed in the guide rail to be coupled to a mounting portion.
The area of the mounting hole is larger than the first mounting block and smaller than the second mounting block.
The distance between every two adjacent mounting holes is smaller than the width of the second clamping groove.
As shown in fig. 3, the installation is completed by the fitting of the installation hole and the first card slot.
When the device is used, before entering a pit for operation, a maintainer firstly moves the car to a (safe) height convenient for the pit operation and then clamps the stopping device on the guide rail below the car. After the operation is finished, the normal operation of the elevator can be recovered after the mechanical stopping device is taken down under the condition that the mechanical stopping device is not stressed.
The above-mentioned specific implementation is the preferred embodiment of the present invention, can not be right the utility model discloses the limit, any other does not deviate from the technical scheme of the utility model and the change or other equivalent replacement modes of doing all contain within the scope of protection of the utility model.
