Description

Technical Field

[0001] The utility model relates to the technical field of rock drill parts, in particular to an oil pipe reel advancing beam. Background Art

[0002] When the rock drill is working, the chain transmission is driven by the reducer to drive the power head to slide along the propulsion beam. The existing power head usually needs to be connected to a hydraulic oil pipe to provide impulse. One end of the hydraulic oil pipe is connected to the power head and the other end is fixed on the propulsion beam. Due to the large sliding range of the power head, the hydraulic oil pipe needs to be of sufficient length to ensure that the hydraulic oil pipe will not be tightened when the power head is farthest from the fixed point of the hydraulic oil pipe. However, when the power head is closest to the fixed point of the hydraulic oil pipe, the hydraulic oil pipe is too long and will cause it to fall. The falling pulling force will affect the life of the hydraulic oil pipe. In addition, the hydraulic oil pipe is in a suspended state, which will also affect the safety of the operation.

The sprocket 51 between the chain 3 and the fixed chain 6 and the roller group 52 for laying the oil pipe, it should be noted that the oil pipe passes through the roller group 52 to form a movable pulley structure so that the oil pipe is always in a tensioned state, one end of the oil pipe is connected to the power head on the power head mounting seat 4, and the other end is connected to the hydraulic oil source after being coiled through the roller group 52. The reducer 2 rotates and is transmitted through the propulsion chain 3 to make the power head installed on the power head mounting seat 4 slide along the propulsion beam body 1. At the same time, the propulsion chain 3 drives the sprocket 51 to rotate, thereby making the oil pipe reel assembly 5 slide along the propulsion beam body 1, realizing the synchronous sliding of the power head mounting seat 4 and the oil pipe reel assembly 5, avoiding excessive tension or relaxation of the oil pipe between the power head and the oil pipe reel assembly 5, and improving the service life of the oil pipe.

[0023] In addition, the oil pipe reel assembly 5 includes a cover 55, which is bolted to the movable plate 54. The propulsion chain 3 passes through the movable plate 54 and the cover 55 and is transmission-connected to the reducer 2. While protecting the propulsion chain 3, the propulsion chain 3 can be avoided.
