Abstract
The invention discloses a bearing temperature measuring device for an elevator traction machine. The traction machine comprises a traction wheel and a machine base. A bearing is installed in the traction wheel. A square groove is formed in the machine base. A thermistor is installed in the square groove. One side of the thermistor makes tight contact with the bearing and the other side of the thermistor is connected with an elevator control module through a circuit. In the operation process of the traction machine, if it is monitored that the temperature of the bearing is abnormal, a power source is cut off instantly, an elevator cannot operate, maintenance personnel can perform an overhaul in time, and potential safety hazards of the elevator in operation are avoided.
Description
technical field:
The invention belongs to elevator technology field, especially relate to a kind of elevator traction machine measuring temperature of bearing device.
background technology:
in the process that elevator runs, towing machine high-speed rotary transfers the operation driving car, and towing machine inside needs to install bearing additional and improves rotating accuracy to reduce friction coefficient.Even if but the friction coefficient of bearing is little again, or wearing and tearing can be produced in long-time operation process at a high speed, once after bearing weares and teares, it can produce a large amount of heat in operational process, this needs the bearing more renewed to ensure the normal work of towing machine with regard to indication.If do not carry out measuring temperature of bearing, dimension journalist person accurately and timely can not carry out repair and replacement to bearing, and elevator also exists very large potential safety hazard in running at ordinary times.
summary of the invention:
Technical matters to be solved by this invention is: provide a kind of measuring temperature of bearing device that towing machine can be protected normally to run.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of elevator traction machine measuring temperature of bearing device, described towing machine comprises traction sheave and support, in described traction sheave, bearing is installed, described base inner offers square groove, be provided with thermally dependent resistor in described square groove, the side of described thermally dependent resistor and bearing abutting contact, the opposite side of described thermally dependent resistor is connected with elevator controlling modular circuit.
As preferably, described thermally dependent resistor and bearing inner ring phase abutting contact.
As preferably, between described thermally dependent resistor and elevator controlling module, be provided with temperature display module.
As preferably, described base inner also offers the wire casing for being drawn by thermally dependent resistor connection lead, and described wire casing communicates with square groove.
Compared with prior art, usefulness of the present invention is: towing machine is in the process of running, if monitoring bearing temperature finds that bearing temperature is abnormal, then cut off the electricity supply immediately, elevator cannot run, and repair and maintenance personnel overhaul in time, avoids elevator to be in operation and occurs potential safety hazard.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is mounting structure schematic diagram of the present invention.
In figure: 1, traction sheave; 2, support; 21, wire casing; 3, bearing; 4, thermally dependent resistor; 5, elevator controlling module; 6, temperature display module.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of elevator traction machine measuring temperature of bearing device as shown in Figure 1, described towing machine comprises traction sheave 1 and support 2, in described traction sheave 1, bearing 3 is installed, described support 2 inside offers square groove, thermally dependent resistor 4 is installed in described square groove, the side of described thermally dependent resistor 4 and bearing 3 abutting contact, the opposite side of described thermally dependent resistor 4 is connected with elevator controlling module 5 circuit.When the temperature that the temperature that thermally dependent resistor 4 detects is preset higher than elevator controlling module 5, elevator controlling module 5 is cut off the electricity supply, and elevator is out of service, waits for that repair and maintenance personnel come to keep in repair.
In order to avoid thermally dependent resistor 4 is exposed to outside support 2, described thermally dependent resistor 4 and bearing 3 inner ring phase abutting contact.
Temperature display module 6 is provided with between described thermally dependent resistor 4 and elevator controlling module 5, the actual temperature of testing can be presented on temperature display module 6 by thermally dependent resistor 4 timely, clearer information is intuitively shown to staff, whether due to elevator controlling module 5 maloperation cause elevator out of service, accelerate the overhaul efficiency of repair and maintenance personnel and the accuracy of maintenance if can investigate simultaneously.
Described support 2 inside also offers the wire casing 21 for being drawn by thermally dependent resistor 4 connection lead, and described wire casing 21 communicates with square groove.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
