Description

  The present invention relates to a support device for supporting an explosive loading cylinder for an explosive loading device used when, for example, a charge hole drilled in a face of a rock is remotely loaded with an explosive.

  Conventionally, the explosive loading device having a loading machine and an explosive loading hose connected to the loading machine is remotely pumped with a packaged explosive by compressed air and loaded into a charge hole drilled on the face of a rock bed or the like. The method is known. In other words, the loading operator inserts the explosive loading hose into the charging hole, and after that, packs the explosive with compressed air and loads it into the charging hole. In addition, it was necessary to operate the explosive loading hose at a location at least 2 to 3 m away from the face. Therefore, it has been necessary to remotely load the package explosive into the charge hole. For this reason, the longer the loading operator moves away from the face, the more uneven the face, and the longer the time required to insert and remove the explosive loading hose from the charge hole, and packaging in one charge hole. After loading the explosive, the explosive loading hose insertion / removal operation is repeated in the next charge hole. Therefore, if the insertion / removal operation takes a long time, there is a possibility that it will impose a heavy burden on the operation of the loading operator. Incidentally, the hole diameter of the charge hole is usually about 45 mm, and the outer diameter of the explosive loading hose is usually about 20 to 38 mm.

  Then, the auxiliary tool 50 of an explosive loading hose as shown in FIG. 9 is proposed (for example, refer patent document 1). That is, the auxiliary tool 50 is connected to the semi-cylindrical tube slider 51, a shoulder member 52 provided in the middle of the tube slider 51, and the tip of the tube slider 51, and engages with the lip of the charge hole. The engaging member 53 is provided. Then, the shoulder member 52 of the tube slider 51 is hung on the shoulder of the loading operator, the explosive loading hose is placed on the tube slider 51, and the engaging member 53 is engaged with the mouth edge of the charging hole, thereby The operability of the explosive loading hose can be improved when packing explosives are loaded into the hole.

The explosive loading device used here has a hopper for storing a large amount of packaging explosive, a scraping machine comprising a conveyor for taking out the packaging explosive from the hopper, and a packaging explosive from the scraping machine to the loading machine. It has a chute etc. for guiding. These are mounted on the vehicle's loading platform, a large wheel jumbo is placed in front of the vehicle, and a long explosive loading hose connected to the loading machine extends to the loading worker on the wheel jumbo service basket. . The explosive loading hose is considerably large and large, such that the loading operator operates it. The loading of the package explosive to the loading machine in this method is not manual but automatic, but insertion / removal of the explosive loading hose to / from the charge hole is manual, in which case the tube slider 51 is used.

  However, the tube slider 51 has a length of 3 m or more and is lowered from the shoulder, so that the workability during loading is improved. In addition, an explosive loading hose is loaded. In particular, the longer the explosive loading hose is, the larger the load is, and the movable range of the explosive loading hose is narrow in the vertical and horizontal directions. You have to turn to. In addition, if this loading operation is performed on the service basket of the wheel jumbo, the space of the service basket is narrow, so when loading other operations, such as explosives or contents, for example, manual loading In this case, the tube slider 51 must be lowered from the shoulder and loaded with explosives or the like. Therefore, the operability of the explosive loading hose is not yet satisfactory, and there is also a problem that a separate explosive loading hose loading / unloading device is required for the movement in the length direction (forward and backward movement) of the explosive loading hose.

  Accordingly, an object of the present invention is to provide a support device for an explosive loading cylinder that can remarkably improve the workability when loading explosives and contents (hereinafter referred to as explosives) into a charge hole. There is to do.
