Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance application, in particular to a novel elevator mechanical blocking device. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. Simply put, it is a fixed lifting device that serves specified floors. A vertical lift elevator has a car that runs between at least two rows of rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. Because of the special working environment of the elevator, it needs to be maintained and repaired periodically. The maintenance or repair of the elevator requires staff to enter the elevator shaft to operate. Although the car has stopped working at this time, it is still relatively dangerous. How to limit the accidental movement of the car and provide a protective shelter for the staff to protect personnel is a problem that each elevator manufacturer needs to face and consider.

[0003] The existing mechanical parts manufacturing process of the blocking device structure is very complicated, and the requirements for the electrical and parts appearance and precision are relatively high, thereby increasing the manufacturing cost. Therefore, it is necessary to provide an elevator mechanical blocking device with a simple and reasonable structure, safety and stability, and low cost. Utility Model Content

[0004] The utility model aims to provide a novel mechanical blocking device for elevators, so as to ensure that during the maintenance of the elevator, the life safety of maintenance personnel can be protected by mechanical blocking.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel elevator mechanical stopping device comprises: a vertical pipe, a rotating plate, a connecting plate, a fixed plate, a hinge, a pressure guide plate, a limit switch, a rubber pad and a slide. The vertical pipe is firmly welded to the rotating plate, the connecting plate is firmly welded to the rotating plate, the connecting plate is connected to the fixed plate by a slide and can rotate at an angle, the limit switch is fixed to the fixed plate by a fastening screw, one side of the hinge is welded to the rotating plate, and the other side of the hinge is welded to the fixed plate, and the rubber pad is bonded to the upper and lower ends of the vertical pipe.

[0007] The limit switch is a contact switch.

[0008] The vertical pipe is a support rod. When the elevator is installed, the entire device is fixed on the guide rail of the elevator by means of a pressure guide plate through bolts.

[0009] When the elevator is in normal working state, the device of the utility model is in a horizontal swing state, avoiding the up and down running route of the elevator, and at this time, the contact switch has no signal transmission.

[0010] When the elevator is installed or maintained, the car stops running and the device is in a 90-degree swing angle state. The rotating plate hits the limit switch, that is, the contact switch, and the vertical pipe is used to support the car. This can effectively limit the accidental movement of the car, provide a safe haven for the staff, and protect the personnel.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The materials required for this utility model are common and cheap;

[0013] (2) The preparation process of the utility model device is simple and the production cycle is short;

[0014] (3) This device is easy to install, simple to operate, easy to install and maintain, safe, reliable and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , 2 As shown in Figure 3, a new type of elevator mechanical blocking device includes: a vertical pipe 1, a rotating plate 2, a connecting plate 3, a fixed plate 4, a hinge 5, a pressure guide plate 6, a limit switch 7, a rubber pad 8 and a slide 9. The vertical pipe 1 is firmly welded to the rotating plate 2, the connecting plate 3 is firmly welded to the rotating plate 2, the connecting plate 3 is connected to the fixed plate 4 by a slide 9 and can rotate at an angle, the limit switch 7 is fixed to the fixed plate 4 by a fastening screw, one side of the hinge 5 is welded to the rotating plate 2, and the other side of the hinge 5 is welded to the fixed plate 4, and the rubber pad 8 is bonded to the upper and lower ends of the vertical pipe 1.

[0020] The limit switch 7 is a contact switch. When the elevator is installed, the whole device is fixed to the guide rail of the elevator using the pressure guide plate 6 and the required fastening bolts. When the elevator is working normally, the device is in a horizontal swing state, avoiding the up and down running route of the elevator, and there is no signal transmission from the limit switch 7. When the elevator is installed or maintained, the car stops running, the device is in a 90-degree swing angle state, the rotating plate 2 hits the limit switch 7, and the vertical pipe 1 supports the car to limit the accidental movement of the car.
