The auxiliary maintenance device is used for increasing the capacity space of the pit 80 when the elevator breaks down and needs maintenance personnel to enter the pit 80 for maintenance operation, so that the lift car 20 can stop at a position higher than the pit 80.

As shown in fig. 1, a schematic view of an application and installation of an auxiliary service apparatus shown in an embodiment of the present application includes: a first base 10, a padding member 40 and an additional buffer 50. The first base 10 is used to carry the fixed raised pad 40 and the additional buffer 50 when the elevator enters a service state. The step-up member 40 is used to assemble the additional bumper 50 to the first base 10 and to ensure that the installed additional bumper 50 is higher than the original bumper 30 in the pit 80. And an additional buffer 50, as the name implies, for buffering and stopping the descending car 20 at a position higher from the pit 80. It should be noted that the position of the car 20 at a higher position from the pit 80, at least the height position of the car 20, ensures that the head does not collide with the bottom of the car 20 when the inspection worker stands upright in a squatting position after entering the pit 80. Of course, it is preferable to allow the service person to perform the service in a standing position.

Specifically, the first base 10 is used for being installed in the pit 80 and located in a projection area of the bottom wall of the car 20, and is located on one side of the original buffer 30; the block-up member 40 is disposed on the first base 10; the additional buffer 50 is disposed on the elevating member 40, and the top of the additional buffer 50 is higher than the top of the original buffer 30.

To sum up, the implementation of the technical scheme of the application has the following beneficial effects: the auxiliary maintenance device of the scheme is applied to an old building and an elevator, and the depth of the elevator pit 80 is shallower than the national standard specified depth, so that the auxiliary maintenance device is used for assisting maintenance personnel to safely and conveniently carry out elevator maintenance operation. Specifically, when the auxiliary maintenance device is used, the first base 10 needs to be fixed in the pit 80 in advance, specifically, installed at the adjacent side of the original buffer 30 and in the projection area of the bottom wall of the car 20; when the elevator needs to be overhauled, after the car 20 moves upwards and leaves the pit 80, the pre-assembled additional buffer 50 and the heightening member 40 are installed on the first base 10, due to the height of the heightening member 40, the first base 10 and other parts, the top of the installed additional buffer 50 can be higher than the original buffer 30 by a certain amount, when the car 20 moves downwards, the bottom of the car 20 abuts against the additional buffer 50 and is stopped, at this time, compared with the original buffer 30, the height between the car 20 and the pit 80 is greatly increased, namely, the space between the pit 80 and the car 20 for accommodating the maintainer is correspondingly increased, so that the maintainer can climb into the pit 80 to overhaul in a sufficient space, the difficulty in overhauling is greatly reduced, and under the protection of the additional buffer 50, the car 20 can not hurt the maintainer in the pit 80 below, the potential safety hazard is eliminated.

It should be noted that the original buffer 30 and the additional buffer 50 may be any buffer device that can be applied to buffering of an elevator car bottom in the related art, such as, but not limited to, a hydraulic buffer, an energy storage buffer, a spring buffer, etc., and are not limited thereto.

The additional buffer 50 is attached to the first base 10 and then is required to be located in the projection area of the bottom wall of the car 20, in order to ensure that the additional buffer 50 can be brought into contact with the bottom wall of the car 20 after the car 20 moves downward and ensure the buffer stop capability for the car 20. Preferably, the additional buffer 50 is mounted directly below the middle of the bottom wall of the car 20.

In addition, in order to reduce the number of parts, facilitate the mounting and dismounting operations, and improve the supporting capability of the car 20, the additional buffer 50 in this embodiment is preferably integrated with the step-up member 40. For example, the two are assembled into a whole by welding, and the connection strength is high. In this embodiment, the padding member 40 may have various structures or shapes, such as a cylinder, a block, etc., and may be selected according to actual needs, which is not limited herein.

In one embodiment, the first base 10 is locked on the ground of the pit 80 by anchor bolts, the first base 10 is opened with a first receiving cavity, and the block-up member 40 is inserted into the first receiving cavity. Therefore, the heightening element 40 is limited and restrained by the first accommodating cavity, so that firm installation can be ensured, the additional buffer 50 is prevented from rolling when being subjected to the impact pressure of the upper car 20, and the buffer is ensured to have reliable buffering and supporting capacity.

In order to further improve the connection strength, in an embodiment, the inner wall of the first accommodating cavity is provided with a first thread, the outer wall of the heightening element 40 is provided with a second thread, and the first thread is in threaded connection with the second thread. Of course, in other embodiments, other connection methods in the prior art may be adopted instead of the above-mentioned screwing method, such as snap connection, magnetic attraction connection, adhesion, etc., which may be specifically selected according to the actual needs of those skilled in the art.

With reference to fig. 1, in addition, the auxiliary maintenance device further includes a first trigger sensor 60 disposed on the first base 10, the block 40 has a trigger body 41, the first trigger sensor 60 is configured to be in trigger fit with the trigger body 41, and the first trigger sensor 60 is configured to be electrically connected to an elevator main control loop. That is, only after the first trigger sensor 60 detects that the padding member 40 is installed in place, that is, after the additional buffer 50 is installed on the first base 10, the first trigger sensor 60 will feed back a signal to the elevator main control loop, so that the elevator enters the maintenance state, at this time, the car 20 will move downward to contact with the additional buffer 50, and the car 20 will not fall down accidentally under the protection of the additional buffer 50, so as to cause personal injury to the maintenance personnel. Also the active security protection capability of the auxiliary maintenance device is further improved by the active detection means.

With continued reference to fig. 2 and 3, in practice, the elevator is still able to operate under normal operating conditions most of the time, and it is necessary to remove the elevating elements 40 and the additional buffer 50 from the first base 10 and place them in a safe place to ensure that the car 20 can normally descend to the pit 80 at the predetermined leveling position. In order to store and store the elevating member 40 and the additional buffer 50 without affecting the use in the next maintenance, in a further embodiment, the auxiliary maintenance device further includes a second base 70, the second base 70 is used for being installed at the edge position of the pit 80 and outside the projection area of the bottom wall of the car 20, and the elevating member 40 and the additional buffer 50 are used for being installed on the second base 70. Thus, when the elevator is overhauled and needs to normally run, the heightening piece 40 and the additional buffer 50 can be integrally detached from the first base 10 and then installed on the second base 70, and the heightening piece 40 and the additional buffer 50 can also be positioned outside the projection area of the bottom wall of the car 20 at the moment, so that the car 20 cannot collide and interfere with the car 20 after descending, and the normal running of the elevator can be ensured.

The second base 70 is provided with a second accommodating cavity, and the heightening member 40 is inserted into the second accommodating cavity. Therefore, the heightening element 40 is limited and restricted by the second accommodating cavity, so that the installation is ensured to be firm.

It is easily understood that the transfer of the padding member 40 and the additional buffer 50 from the first base 10 to the second base 70 can be performed by a manual operation of the service man, but the manual operation mode depends on the service man, which increases the workload and the labor intensity of the service man to some extent. Preferably, the transfer operation is performed by automated equipment.

In an embodiment, the auxiliary maintenance device further includes a lifting driving module disposed on the second base 70, a rotation driving module connected to the lifting driving module, and a clamp connected to the rotation driving module, and the clamp is connected to the raising member 40. In this way, after the maintenance is completed, the lifting driving module is lifted upwards to pull the padding member 40 out of the first base 10; then, the rotation driving module acts to drive the heightening member 40 and the additional buffer 50 to rotate to the position right above the second base 70, and then the lifting driving module descends downwards, so that the heightening member 40 can be inserted into the second accommodating cavity of the second base 70 to complete the storage. The whole shifting operation process can be carried out after the maintainers leave the pit 80, manpower participation is not needed in the whole process, the labor intensity is favorably reduced, meanwhile, the staying time of the maintainers in the pit 80 is reduced, and the personal safety is ensured.

In order to further enhance the connection strength between the second base 70 and the heightening member 40, in another embodiment, the inner wall of the second accommodating cavity is provided with a third thread, the outer wall of the heightening member 40 is provided with a fourth thread, and the third thread is screwed with the fourth thread. Of course, in other embodiments, other connection methods in the prior art may be adopted instead of the above-mentioned screwing method, such as snap connection, magnetic attraction connection, adhesion, etc., which may be specifically selected according to the actual needs of those skilled in the art.

In addition, in this scheme, the auxiliary maintenance device further includes a second trigger sensor 90 disposed on the second base 70, the block-up member 40 is provided with a trigger body 41, the second trigger sensor 90 is used for being in trigger fit with the trigger body 41, and the second trigger sensor 90 is used for being electrically connected with the elevator main control loop. That is, only when the second trigger sensor 90 detects that the raising member 40 is installed in place, it can indicate that the additional buffer 50 has been removed from the first base 10, and at this time, the second trigger sensor 90 will feed back a signal to the elevator main control loop to enable the elevator to enter the running state, and at this time, the car 20 will normally descend to a position close to the pit 80. Above-mentioned initiative detection means can avoid taking place 20 mistake downlinks of car, and the personal injury accident that causes the maintainer when the maintainer has not left pit 80 does not do benefit to the safety and the reliable performance that promote the elevator.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
