Problems solved by technology

[0002] At present, when using a chargeer or a charge vehicle to carry out the operation of filling the mixed explosives in the underground mine to the blast hole, the drug delivery pipe needs to be manually inserted into the blast hole, which is labor-intensive and inefficient for the workers; and there is another delivery method : Use friction wheel to convey
One end of the drug delivery tube is connected to the outlet of the pumping device of the charging vehicle, and the drug delivery tube passes through one or more pairs of friction wheels, and the friction force generated by the friction wheels is used to realize the upward delivery of the drug delivery hose; in this group of friction Behind the wheel is a flexible mechanical arm, through which the drug delivery tube is aligned with the blast hole; the disadvantage of this device structure is that the drug delivery tube is greatly worn, and there is a problem of drug delivery tube slipping during the delivery process, which affects Charge accuracy, and the flexible robotic arm has high requirements for processing and control accuracy, and the production cost is too high

Embodiment 1

[0025] Embodiment 1. In this embodiment, electric power is selected to work as the power source 6 of the lead screw. The power source 6 of the lead screw adopts an explosion-proof variable frequency motor, the clamping part adopts an electromagnetic device, and the power source 14 of the clamping adopts an electromagnet;

[0026] The whole device consists of three parts: a bracket part, a guide rail part and a clamping part.

[0027] The support part includes a support 5, a turret 3 and a lock 9; the support 5 is a support base of a fixed truss structure, the turret 3 is a rotatable disk frame composed of two rotating shafts, and the turret 3 passes through the bearing Connected with the bracket 5, the main function is to support the rotation of the whole device and the guide rail, and the locking device 9 is installed on one side of the bracket.

[0028] The guide rail part includes a guide rail seat 11, a reciprocating lead screw 2, a guide post 1, a power source 6 for the l...

Embodiment 2

[0033] Embodiment 2. In this embodiment, when hydraulic pressure is used as the power source of the screw, the power source of the screw is a hydraulic motor, the clamping part is a hydraulic device, and the power source of the clamping is a hydraulic cylinder.

[0034] This embodiment except clamper, other structures are identical with embodiment 1;

[0035] The clamper includes a base 13, a hydraulic cylinder, a spring 15, a clamping block 16, a clamping head 17 and a spacer 18, wherein the clamping block 16 is a pair of polygonal structures symmetrical to the drug delivery tube 8, A pair of clamping blocks 16 are sleeved on the base 13 through the pins, and the spring 15 is arranged on the pins, connected with the base 13 and the clamping block 16, and plays the role of pre-tightening and reset, and the two ends of the hydraulic cylinder are clamped by the pins The block 16 is connected, and the clamp head 17 is lined with a block 18;

[0036] The material of the pad 18 is...
