Abstract
The utility model relates to a wire collecting machine, in particular to an automatic protection device for a wire collecting machine lifting transmission mechanism. The automatic protection device comprises a motor and a base, a screw rod is connected on an output shaft of the motor, a bearing support is arranged on the outer side of the screw rod, the bearing support is connected with a motor, a plane bearing arranged in the bearing support, a pin shaft is fixed on the bearing support, and the pin shaft is in contact with a stroke switch on the base. By means of the structure, when a wire coil lands, the screw rod can drive the pin shaft to move upwards, and the pin shaft in contact with the stroke switch can be separated. The stroke switch can generate signals to a controller, the controller can control the motor to stop working, and the purpose of protecting the wire coil and the motor is achieved.
Description
Technical field
The utility model relates to a kind of admission machine, particularly a kind of device of automatic protection admission machine elevating drive mechanism.
Background technique
The cable admission machine need to be lifted into the drum of rolling suitable position after with cable coiling rolling.When the drum on the admission machine elevating drive mechanism landed, drum can produce impact force upwards, and this moment, motor still can work, and all can cause damage to drum equipment and motor like this, can't automatically protect the admission machine elevating drive mechanism.
Summary of the invention
The utility model technical issues that need to address provide a kind of device that can automatically protect the admission machine elevating drive mechanism.
For solving above-mentioned technical problem; the automatic safety device of the utility model admission machine elevating drive mechanism comprises motor and pedestal; be connected with screw mandrel on the described motor output shaft; described screw mandrel arranged outside has bearing support; described bearing support is connected with motor; be provided with plane bearing in the described bearing support, be fixed with bearing pin on the described bearing support, described bearing pin be fixed on the pedestal upper stroke switch and contact.
Further, be provided with the rotation framework type sealing ring between described screw mandrel and the bearing support.
After adopting said structure, when drum landed, leading screw can drive bearing pin and move up, and originally will separate with the contacted bearing pin of position limit switch.Position limit switch produces signal to controller, and controller control motor quits work, and reaches the purpose of protection drum and motor.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 is motor, and 2 is pedestal, and 3 is screw mandrel, and 4 is bearing support, and 5 is plane bearing, and 6 is bearing pin, and 7 are the rotation framework type sealing ring
Embodiment
As shown in Figure 1, the automatic safety device of the utility model admission machine elevating drive mechanism comprises motor 1 and pedestal 2.Be connected with screw mandrel 3 on the described motor output shaft, described screw mandrel 3 arranged outside have bearing support 4, and described bearing support 4 is connected with motor 1.Be provided with plane bearing 5 in the described bearing support, because plane bearing mainly bears thrust load, under very little space, can obtain high loadability and high rigidity, can better carry the impact that brings when drum lands like this.
Be fixed with bearing pin 6 on the described bearing support 4, described bearing pin 6 be fixed on pedestal 2 upper stroke switch and contact.When the drum on the leading screw 3 landed, screw mandrel 3 can drive bearing pin and move up, and original so contacted bearing pin and position limit switch can separate.Position limit switch can send a signal to controller, and controller control motor quits work, and automatically protects motor.
Be provided with rotation framework type sealing ring 7 between described screw mandrel 3 and the bearing support 4, in case the too fast consumption of grease in the bearing support.
Claims (2)
1. the automatic safety device of an admission machine elevating drive mechanism; comprise motor and pedestal; be connected with screw mandrel on the described motor output shaft; described screw mandrel arranged outside has bearing support; described bearing support is connected with motor; be provided with plane bearing in the described bearing support, it is characterized in that: be fixed with bearing pin on the described bearing support, described bearing pin be fixed on the pedestal upper stroke switch and contact.
2. according to the automatic safety device of admission machine elevating drive mechanism claimed in claim 1, it is characterized in that: be provided with the rotation framework type sealing ring between described screw mandrel and the bearing support.
