Embodiment 1

[0030] Due to the backward development of the local area, there are no such accessories in the local area and neighboring countries, so the nearby purchase can only be given up. Observation and analysis of the rubber sleeve of the drill supporter shows that this accessory must be wear-resistant, tough and elastic, and can hold the drill pipe well on the boom of the drilling rig. After analysis, at this time the artificial aggregate production system on the construction site has replaced many scrapped conveyor belts, which happen to have properties such as wear resistance, toughness, and elasticity, and the conveyor belt contains multiple layers of fibers, which have better toughness and stability. Using the scrapped aggregate conveyor belt of the artificial aggregate production system, a durable and replaceable rubber sleeve for the brazing device was designed and manufactured, successfully turning waste into treasure.

Embodiment 2

[0047] Such as Figure 2-3 Shown, a kind of multi-arm drilling propeller rubber sleeve of the present invention, the long 11cm of brazing device rubber sleeve before making (can determine the making size of brazing device rubber sleeve according to actual needs), wide and high 8cm, the center is diameter 4cm hole. The scrap aggregate conveying width is 650cm~1000cm, and the thickness is 1.1~1.2cm. Cut the conveyor belts of different widths into 8cm×8cm aggregate conveyor belt block 1 with a shearing machine (you can also install the self-made blade on the four-post press to cut the strips); D=4cm) extrude the circular drill pipe through hole 2, open the installation hole 3 (D=6mm) respectively with a four-column press at two corners on one side, the center of the hole is 1cm from the adjacent two sides, when opening the hole, It is best to make a right-angled L-shaped slot and fix the aggregate conveyor belt block 1 on the drilling machine to prevent the block from rotating ...

Embodiment 3

[0049] Such as Figure 2-3 Shown, a kind of preparation method of dobby drill propeller rubber sleeve, comprises steps:

[0050] Step 1, using the scrapped aggregate conveyor belt to cut and make the aggregate conveyor belt block 1;

[0051] Step 2, opening a drill pipe through hole 2 at the center of the aggregate conveyor belt block 1;

[0052] Step 3. Open a mounting hole 3 at two corners of one side of the aggregate conveyor belt block 1;

[0053] Step 4. Stack nine aggregate conveyor belt cubes 1, and use bolts 4 to connect and fix the superimposed aggregate conveyor belt cubes 1 in series through installation holes 3 to form a brazing device rubber sleeve.

Abstract

The invention discloses a dobby drill dill-rod lifter rubber sleeve and a manufacturing method thereof. The method comprises: using a scrapped aggregate conveyor belt to make an aggregate conveyor belt block, arranging a drill stem hole on the center of the aggregate conveyor belt block, respectively arranging an installing hole on two corners of one edge of the aggregate conveyor belt block, overlaying more than two aggregate conveyor belt blocks, and using a bolt to connect and fix the integrated overlaid aggregate conveyor belt blocks through the installing holes. The scrapped aggregate conveyor belt is used to manufacture the dobby drill dill-rod lifter rubber sleeve, manufacturing cost is low, and the rubber sleeve is simple in structure and is practical. The scrapped aggregate conveyor belt is used to manufacture the dobby drill dill-rod lifter rubber sleeve, the dobby drill dill-rod lifter rubber sleeve is wear-resisting and durable, replacement period is long, and labor replacement is saved. The self-made dobby drill dill-rod lifter rubber sleeve does not need a purchasing link, and solves problems that purchasing is hard in backward areas, and solves problems of purchasing of dill-rod lifter rubber sleeves and high transportation cost.

Description

technical field [0001] The invention relates to the field of a rubber sleeve for a dobby drill, in particular to a rubber sleeve for a dobby drill and a preparation method thereof. Background technique [0002] The rubber sleeves of the brazing device are all made of rubber, and are mainly used for straightening and limiting the drill pipe during the construction operation of the dobby drill, such as figure 1 As shown, the existing brazing device rubber sleeve is a cuboid integral structure, and the cuboid is provided with a through hole for inserting a drill pipe. [0003] The Karuma Tailgate Tunnel in Uganda is a large-section tunnel, and the amount of system support bolt drilling is huge. In order to ensure production, three dobby drills were deployed for bolt drilling construction. Because the dobby drill consumes a lot of rubber sleeves for the brazing device in the actual use process, and because the project is located in Africa, the transportation is inconvenient, th...
