[0002] With the extensive research and application of pipeline directional drilling crossing projects at home and abroad, directional drilling design technology has developed rapidly, and the crossing capacity has been greatly improved. Among them, horizontal directional drilling rigs are the most widely used. Horizontal directional drilling rigs use the method of jacking or drilling to first form a pilot hole in the crossing area, and then take corresponding methods to expand the borehole to the required aperture according to the actual project situation, and then complete the pipeline laying. In this process, a large number of drill rods are required, and the capacity of the drill rod box is fixed. The number of drill rods in a drill rod box cannot meet the needs of long-distance drilling. At this time, it is necessary to manually add drill rods to the box.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-3 As shown, a fully automatic multi-column rod loading device includes a drill rod loading and unloading device 1 and an auxiliary rod loading device 2. The two devices are separated by a certain distance and are usually not connected to each other. The drill rod loading and unloading device 1 includes a bracket assembly 11, a drill rod box 12, a jacking device 13, and a shuttle arm assembly 14. The drill rod box 12, the jacking device 13, and the shuttle arm assembly 14 are all installed on the bracket assembly 11. Figure 8 As shown, the support assembly 11 includes two vertical rods 11-1 and a horizontal rod 11-2. The horizontal rod 11-2 is located between the two vertical rods 11-1 and is vertically arranged with the vertical rods 11-1. The drill rod box 12 is mounted on the two vertical rods 11-1. Figure 3 As shown, the drill rod box 12 includes two boxes 12-1 set opposite to each other, and the two boxes 12-1 are connected and fixed by a plurality of connecting rods, and a plurality of rows of drill rod slots are separated in the boxes 12-1. The jacking device 13 includes a jacking cylinder 13-1, a jacking bracket 13-2 (such as Figure 7 As shown), the jacking mounting seat 13-3 is fixed on the cross bar 11-2, the jacking mounting seat 13-3 is a sleeve, the lower end of the jacking bracket 13-2 is sleeved in the jacking mounting seat 13-3 and can move up and down in the jacking mounting seat 13-3, the lower end of the jacking cylinder 13-1 is fixed on the jacking mounting seat 13-3, and the upper end is connected to the jacking bracket 13-2.

[0022] The lifting device 13 is located directly below the drill rod box 12. The shuttle arm assembly 14 includes a transmission device 14-1, a shuttle arm 14-2 and a shuttle arm mounting seat 14-3. The shuttle arm mounting seat 14-3 is mounted on the cross bar 11-2. The shuttle arm 14-2 is horizontally arranged and vertically arranged with the cross bar 11-2. The shuttle arm 14-2 can move forward and backward along the length direction of the shuttle arm 14-2 under the drive of the transmission device 14-1. Figure 4-5As shown, the auxiliary rod-lifting device 2 includes a column 21, a winch 22, a motor 23, and a lifting platform 24. The column 21 is hollow, the winch 22 is connected to the motor 23 and installed on the upper part of the column 21, and the lifting platform 24 is connected to the winch 22 through a wire rope. The lifting platform includes a lifting body 24-1 and a support block 24-2. The lifting body 24-1 is located inside the column 21, and the support block 24-2 is located outside the column 21. A plurality of drill rod grooves II24-2-1 are provided on the support block.

[0023] like Figure 6 As shown, a plurality of continuously arranged drill rod grooves 114-2-1 and a translation surface 14-2-2 are provided on the upper portion of the shuttle arm 14-2.

[0024] The number of drill rod grooves on the shuttle arm 14-2 is the same as the number of drill rod rows in the drill rod box 12. In this way, the number of drill rods received by the shuttle arm 14-2 from the auxiliary rod loading device 2 corresponds to the number of drill rod placement spaces in the drill rod box 12, and the rod loading efficiency is improved.

[0025] The transmission device 14-1 includes a gear and a rack, and the rack is fixed to the bottom of the shuttle arm 14-2.

[0026] The working principle of the device is as follows: a group of drill rods 3, each group of four, is placed on the support block 24-2 in the auxiliary rod-lifting device 2, and then lifted by the winch 22. At this time, the shuttle arm 14-2 extends, and its drill rod groove I14-2-1 moves to the right below the drill rod 3, and then the winch 22 falls, and the drill rod groove I14-2-1 can just receive four drill rods. Then the shuttle arm 14-2 retreats, so that the four drill rods 3 are at the bottom of the drill rod box 12, and the drill rod box 12 is divided into four rows of empty spaces, and the four drill rods 3 are located in the four rows of empty spaces. If the second group of drill rods 3 is to be installed, the lifting device 13 lifts the first group of drill rods 3 to make it separate from the drill rod groove I14-2-1, and the shuttle arm 14-2 extends. At this time, the four drill rods 3 of the first group are still supported by the shuttle arm 14-2, and its support point is placed on the translation surface 14-2-2. Although the translation surface 14-2-2 will move forward, the first group of drill rods 3 will still stay on the translation surface 14-2-2 by rolling or sliding. When the second group of drill rods 3 reaches the bottom of the first group of drill rods 3, four upper and lower rows are formed in the drill rod box 12, with two drill rods 3 in each row. And so on, the Nth group is installed, and its operation is the same as that of the first and second groups.

[0027] In the prior art, the number of drill rods 3 in the drill rod box 12 is fixed, and when they are used up, it is necessary to manually replace and install the drill rods, which has low work efficiency. Compared with the prior art, the present invention provides an auxiliary rod loading device 2, and through the cooperation of various components in the loading and unloading device, the drill rods 3 can be automatically loaded into the drill rod box 12, which has a high degree of automation and improved work efficiency.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Various changes that can be made within the knowledge scope of technicians in the relevant technical field without departing from the spirit of the present invention are all within the protection scope of the claims of the present invention.
