Usually, a steel wire rope is used for friction transmission, the steel wire rope bypasses a traction sheave, two ends of the steel wire rope are respectively connected with a car and a balance weight, and a motor drives the traction sheave to lift the car.
The two ends of the traction rope are respectively connected with the lift car and the counterweight and wound on the traction sheave and the guide pulley, the traction motor drives the traction sheave to rotate after speed change through the speed reducer, and the lift car and the counterweight move up and down by virtue of traction force generated by friction between the traction rope and the traction sheave, so as to achieve the purpose of transportation.
The main problems and drawbacks of the prior art include:
in the prior art, when a bearing shaking table is installed in a car of a mining elevator, a detection switch is not arranged, and meanwhile, according to the regulation of safety technical requirements of the mining elevator which appears in 8, 12 and 8 months in 2019, an elevator provided with a bearing device has an interlocking protection function, and when the bearing device is opened, the mining elevator cannot be started and operated; the mining elevator before the new specification is provided with the bearing device without the detection switch, so that potential safety hazards are brought to the operation of the elevator.
SUMMERY OF THE UTILITY MODEL
To the main problem and the defect that exist among the prior art, the utility model provides a cage chair detection device is accepted to mining elevator has improved mining elevator's safe and reliable operation, has got rid of the potential safety hazard of elevator abnormal starting, and simple structure is reliable, and it is convenient to install.
Therefore, the utility model adopts the following technical scheme:
a mining elevator receiving cradle detection device is positioned on a mining elevator car chassis and comprises a left front wall, a right front wall, a cradle detection switch, a receiving cradle and a car chassis; left front wall, right front wall and accept the cage chair and all install on car chassis, cage chair detection switch includes two, installs respectively in the below of left front wall and right front wall position of opening the door.
Preferably, the two cradle detection switches are located in the same horizontal plane, and the cradle detection switches are connected in series on the elevator safety loop.
Preferably, the receiving cradle comprises a receiving mechanism and a car guide rail, the car guide rail is fixed on a car chassis, the receiving mechanism is arranged on one side of the car guide rail, and the receiving mechanism rotates around one end in contact with the car guide rail.
Compared with the prior art, the beneficial effects of the utility model are that:

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are only used for explaining the present invention, but not for limiting the present invention.
As shown in fig. 1 and 2, the utility model discloses a mining elevator receiving cradle detection device, which is positioned on a mining elevator car chassis and comprises a left front wall 1, a right front wall 2, a cradle detection switch 3, a receiving cradle 4 and a car chassis 5; left front wall 1, right front wall 2 all install on car chassis 5 with accepting cage chair 4, cage chair detection switch 3 includes two, installs respectively in the below of left front wall 1 and the 2 positions of opening the door of right front wall.
Specifically, two cradle detection switches are located in the same horizontal plane, and the cradle detection switches are connected in series on an elevator safety loop.
Specifically, as shown in fig. 3 to 6, the receiving cradle 4 includes a receiving mechanism 4-1 and a car guide rail 4-2, the car guide rail 4-2 is fixed on the car chassis 5, the receiving mechanism 4-1 is disposed on one side of the car guide rail 4-2, and the receiving mechanism 4-1 is rotatably movable around one end in contact with the car guide rail 4-2.
Examples
The utility model provides a mining elevator accepts cage chair detection device, is located mining elevator car chassis, includes left antetheca 1, right antetheca 2, cage chair detection switch 3, accepts cage chair 4, car chassis 5, left antetheca 1, right antetheca 2 and accept cage chair 4 and install on car chassis 5, cage chair detection switch 3 installs in the both sides below of left antetheca 1 and right antetheca 2 position of opening the door, and two cage chair detection switch positions need be in same horizontal plane.
When the elevator runs, the door of the elevator is opened, the supporting mechanism 4-1 for supporting the cradle 4 is manually put down, the supporting mechanism 4-1 is placed on the hoistway guide rail 6, the cradle detection switch 3 senses that the switch signal is turned on, and the elevator cannot be started and run at the moment; when the mine car enters or leaves the car, the bearing mechanism 4-1 bearing the cradle 4 is manually retracted and falls on the car guide rail 4-2 bearing the cradle 4, and the elevator can be normally started and operated only when the object cannot be detected by the induction switch signal.
The cradle detection switch 3 can only play a role when the elevator stops at the flat-bed position; on the contrary, when the elevator is in operation and the inductive switch cannot detect the object, the detection switch does not work, so that the normal operation of the elevator is not influenced.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle scope of the present invention should be included within the protection scope of the present invention.
