The embodiment is as follows:
as shown in fig. 1 and 2, the utility model provides a broken shaft protection device for an overhead man-vehicle, which is used in cooperation with the overhead man-vehicle. The shaft breakage protection device for the overhead man car comprises a plurality of positioning pieces 5. The overhead man car comprises a mounting seat 1, a driving wheel 2, a traction rope 3 and a driving shaft 4. The mount 1 is the main support of the device. The mounting seat 1 is used for being fixedly mounted with the inner wall of a mine. The driving wheel 2, the traction rope 3, the driving shaft 4 and other components are fixedly arranged on the mounting seat 1. The drive shaft 4 is connected to the mount 1. The drive wheel 2 is connected to a drive shaft 4. The traction rope 3 is wound on the driving wheel 2. A number of positioning elements 5 are attached to the mounting 1 and located around the driving wheel 2. The spacer 5 is further provided with a support portion 51 for supporting the driving wheel 2 below the edge of the driving wheel 2. Specifically, the driving shaft 4 is vertically disposed and connected below the mount 1. The drive wheel 2 is horizontally disposed and mounted to the drive shaft 4. The traction rope 3 is led in from one side of the driving wheel 2, deflected by 180 degrees by the driving wheel 2 and led out from the other side of the driving wheel 2.
When the shaft breakage protection device for the overhead man car is used, if the driving shaft 4 is broken, the driving wheel 2 loses the support of the driving shaft 4 and further possibly falls. The falling drive wheel 2 falls to the support portion 51 and is supported. Meanwhile, the driving wheel 2 is enclosed by the positioning parts 5 together, so that the driving wheel is prevented from deviating to the side direction and falling off. This is good to avoid the traction rope 3 falling off and slackening as a result of the driving wheel 2 falling directly. Thereby ensuring that the hauling cable 3 can not be loosened too much to cause safety accidents.
In this embodiment, two positioning members 5 are provided. Two positioning parts 5 are oppositely arranged on two sides of the driving wheel 2. The positioning member 5 is provided with a receiving groove 53 that receives the edge of the driving wheel 2. The wrap angle of the accommodating groove 53 to the drive wheel 2 is 60 °. This makes the driving wheel 2 be stopped by the groove wall of the accommodating groove 53 if the driving wheel 4 is dropped downward after the driving shaft 4 is broken, thereby effectively preventing the driving wheel 2 from dropping. In addition, two locating parts 5 wrap up two opposite edges of the driving wheel 2 from two sides, and the driving wheel 2 is prevented from moving to two sides where the locating parts 5 are arranged. The wrap angle of each positioning element 5 to the drive wheel 2 is 60 deg., which prevents the drive wheel 2 from being displaced in a direction perpendicular to the line connecting the two positioning elements 5. So that the drive wheel 2 is well confined between the two positioning elements 5. That is, in the case of breakage of the drive shaft 4, the drive wheel 2 cannot be disengaged from the restriction of the two positioning members 5. Thereby preventing the traction rope 3 from being separated from the driving wheel 2 due to the large displacement of the driving wheel 2 and preventing the traction rope 3 from being loosened greatly due to the large displacement of the driving wheel 2.
In this embodiment, the positioning member 5 is provided with a plurality of fixing holes 52. The positioning member 5 is fixed to the mounting base 1 by a plurality of screws passing through the fixing holes 52. During installation, the driving wheel 2 is installed on the installation seat 1, and then the positioning piece 5 is installed, so that two sides of the driving wheel 2 are wrapped. This makes the installation and replacement of the spacer 5 more convenient.
In this embodiment, a distance sensor 7 is also included. The distance sensor 7 is provided to the positioning member 5. The monitoring end of the distance sensor 7 faces the driving wheel 2. The distance sensor 7 can detect whether the drive wheel 2 is currently deflected downward, and can thus determine whether the drive shaft 4 has a fracture sign. If the driving wheel 2 deflects downwards and is close to the distance from the sensor 7, the controller controls the overhead man car to stop running, and then safety is guaranteed.
In this embodiment, a connecting rod 6 is disposed between the two positioning members 5. The connecting rod 6 is connected to the two positioning members 5 by screws. This results in a closed loop connection between the two positioning members 5, the mounting 1 and the connecting rod 6. Thereby effectively preventing the hauling cable 3 from falling off and falling to the ground.
In this embodiment, the wheel surface of the driving wheel 2 is provided with a wheel groove 21 for accommodating the traction rope 3. The wheel groove 21 prevents the traction rope 3 from easily separating from the driving wheel 2, and the stability of the equipment is guaranteed.
The present invention has been described in terms of the preferred embodiment, and it is not intended to be limited to the embodiment. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
