Description

Technical Field

[0001] The utility model relates to the technical field of reels for engineering vehicles, in particular to a special reel for engineering vehicles. Background Art

[0002] During the construction process of the engineering vehicle, the main part of the hydraulic rock drill needs to move during work, and the hydraulic hose and wire rope will also move with it. In order to prevent the hydraulic hose and wire rope from being entangled with each other, the hydraulic hose and wire rope will be tied together. If they are tied too tightly, the hydraulic hose will be squeezed and flattened, which will hinder the normal passage of hydraulic oil. If they are tied loosely, the tying will not be secure.

[0003] In the existing reel, such as the oil pipe guide tensioning mechanism of the anchor trolley disclosed in the publication (announcement) number: CN219413737U, the oil pipe will be piled up on the oil pipe tensioning wheel, and the trajectory of the oil pipe movement cannot be limited. The moving oil pipe will squeeze other oil pipes, causing the oil pipes to be stacked together. Stacking together for a long time will cause the oil pipes to wear each other, reducing the life of the oil pipes. Utility Model Content

[0019] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Combined with Figures 1 to 4The special reel for engineering vehicles comprises a main mounting seat 13, and a guide mechanism is installed on the rotating end of the main mounting seat 13, through which the hydraulic hose and the wire rope are guided.

[0021] The main mounting seat 13 includes a reel shaft 1301 and a reel tray 1302 . The reel shaft 1301 is welded with the reel tray 1302 , and a guide mechanism is installed on the reel tray 1302 .

[0022] The guide mechanism includes a reel top cover 1, a nut 2, a first bearing 3, a first screw 4, an oil tubing reel 5, a second screw 8, a second bearing 10, and a reel bottom cover 12. The first bearing 3 is installed on the reel shaft 1301 through the nut 2, and the rotating end of the first bearing 3 is fixedly connected to the oil tubing reel 5. The reel top cover 1 is fixedly connected to the top of the oil tubing reel 5 through the first screw 4. The second bearing 10 is located at the bottom end of the reel shaft 1301 and is fixedly connected, and the rotating end of the second bearing 10 is fixedly connected to the reel bottom cover 12. The reel bottom cover 12 is connected to the oil tubing reel 5 through the second screw 8.

[0023] The oil pipe reel 5 is provided with oil pipe chutes arranged at equal distances, and the reel top cover 1 is provided with an oil cup 14 .

[0024] The reel bottom cover 12 is provided with a groove on one side close to the oil pipe reel 5, and a skeleton seal 9 is installed in the groove. The position of the skeleton seal 9 corresponds to the position of the second bearing 10 and is in contact with and connected to the second bearing 10.

[0025] A third bearing 11 is fixedly connected to the reel bottom cover 12, and a wire rope pulley 7 is fixedly connected to the rotating end of the third bearing 11. The wire rope pulley 7 is located between the reel bottom cover 12 and the oil pipe reel 5, and the upper and lower sides of the wire rope pulley 7 are respectively contacted and connected with VD seals 6. The two VD seals 6 are respectively located on the reel bottom cover 12 and the oil pipe reel 5 and fixedly connected, so that the hydraulic hose and the wire rope are placed separately to prevent the wire rope from scratching the hydraulic hose. An arc groove is provided on one side adjacent to the reel bottom cover 12 and the oil pipe reel 5, and the position of the arc groove corresponds to the position of the wire rope pulley 7, so that the hydraulic hose and the wire rope can be moved at the same time, and the connection between the hydraulic hose and the wire rope is avoided.

[0026] The special reel for engineering vehicles is described. When in use, the main mounting seat 13 is installed at the bottom of the rock drilling beam, and the oil pipe and wire rope required for the rock drill are respectively wound on the oil pipe 5 and the wire rope wheel 7. When the rock drill moves forward, under the action of the bearing 3, the second bearing 10, and the third bearing 11, the wire rope will drive the oil pipe reel 5 and the wire rope wheel 7 to rotate independently without affecting each other. In addition, a special groove is opened on the oil pipe reel, and no squeezing will occur when the oil pipes move between each other, thereby reducing the wear of the oil pipe and ensuring the stability of the equipment operation. The reel top cover 1, VD seal 6, and skeleton seal 9 provide a closed working environment for the bearing to avoid external pollution. The oil cup 14 provides grease for the bearing to extend its service life.

[0027] The parts of the present invention that are not described in detail are prior art. Although the present invention is specifically demonstrated and introduced in conjunction with the preferred implementation scheme, there are many methods and ways to implement the technical solution. The above is only a preferred implementation scheme of the present invention. However, technical personnel in the relevant field should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined in the attached claims, which are all within the scope of protection of the present invention.
