Abstract
一种牙轮钻机的上、下钻杆的接头与杆体的连接结构，牙轮钻机技术领域。包括，杆体、钻杆；钻杆由上钻杆、下钻杆组成，上钻杆上有上接头(1)、杆体(2)、连接销子(4)、下接头(3)；下钻杆上也有上接头(1)、杆体(2)、连接销子(4)、下接头(3)；杆体(2)的两端有圆柱孔；将上接头(1)和下接头(3)的圆柱体分别装入杆体(2)的圆柱孔中，用过盈配合连接。然后，在过盈配合处的不同截面钻三个销孔，打进固定销后焊牢。优点在于，由于上钻杆、下钻杆的接头与杆体采取复合连接，在钻孔过程中钻杆就不会折断。并且，该连接方式制作简单，成本低，具有可观的经济效益。
The invention relates to a connection structure between the upper and lower drill pipe joints and the rod body of a roller cone drilling rig, belonging to the technical field of roller cone drilling rigs. Including rod body and drill pipe; the drill pipe is composed of upper drill pipe and lower drill pipe. There are also an upper joint (1), a rod body (2), a connecting pin (4), and a lower joint (3) on the rod; cylindrical holes are arranged at both ends of the rod body (2); connect the upper joint (1) and the lower joint (3) The cylinders of the cylinders are respectively packed into the cylinder holes of the rod body (2) and connected with interference fit. Then, drill three pin holes in different sections of the interference fit, drive into the fixed pin and weld it firmly. The advantage is that, because the joints of the upper drill pipe and the lower drill pipe are combined with the rod body, the drill pipe will not be broken during the drilling process. Moreover, the connection method is simple to manufacture, low in cost, and has considerable economic benefits.
Description
Technical field
The utility model relates to the rotary drill technical field, and the joint and the body of rod syndeton of the upper and lower drilling rod of a kind of rotary drill is provided especially, is useful in being connected of the tool joint on the drilling machine and the body of rod.
Background technology
In the mining machine in iron and steel industry mine, rotary drill is the machinery of holing on the mine, its drilling depth is according to the height decision of the face in mine, the height that 15 meters, 20 meters face is arranged, so what run of steel was the longest is 22 meters, divide three body and function taper threads to connect, be respectively drilling rod, following drilling rod and virtual calibrator for instrument transformer.The joint of upper and lower drilling rod adopted with being connected of the body of rod in the past and was threaded, taper hole cooperates and weld compound the connection.Being connected in the boring procedure like this is easy to fracture from the junction of the joint and the body of rod, after drilling rod fractures, following half-section that fractures and virtual calibrator for instrument transformer all fall in the hole of boring, can't take out, comprise that the hole of having bored destroys together, cause the economic loss of units up to a million every year.
Summary of the invention
The purpose of this utility model is to provide the joint and the body of rod syndeton of the upper and lower drilling rod of a kind of rotary drill, solved the technical problem that the joint of last drilling rod and following drilling rod is connected with the body of rod, propose a kind of can with the joint of upper and lower drilling rod with adopt a kind of new type of attachment being connected of the body of rod, the purpose that drilling rod does not fracture when reaching boring.
The utility model comprises: the body of rod, drilling rod, and drilling rod is made up of last drilling rod, following drilling rod, top connection is arranged on the last drilling rod, on the drilling rod lower contact is arranged down; There is cylindrical hole at the two ends of the body of rod, and an end of top connection and lower contact is a taper thread, and the other end is the cylinders of body of rod two ends with diameter, and the cylinder of top connection and lower contact is respectively charged in the cylindrical hole of the body of rod, connect with interference fit.The joint of last drilling rod, following drilling rod is taked compound the connection with the body of rod, promptly connects the compound connected mode that pins are fixed and welded with three on different cross section.
Bore 3 holes in the junction of the body of rod and joint, each hole its objective is the loss of strength that reduces the body of rod in the position, a hole of axially staggering, and loads onto three in the hole and connects pins and fix, and adopts interference fit to connect, and then steady pin and joint and body of rod junction is welded.
The compound connected mode that interference fit connects and fixes and weld with three steady pins on different cross section.
The beneficial effects of the utility model are
Because the joint of last drilling rod, following drilling rod and the body of rod take compound being connected in the boring procedure just can not fracture.And this connected mode is made simple, and cost is low, has considerable economic.
Description of drawings
Fig. 1 is the utility model drilling rod schematic diagram.Wherein, last drilling rod 5, following drilling rod 6, virtual calibrator for instrument transformer 7, drill bit 8
Fig. 2 is a drilling rod schematic diagram on the utility model.Wherein, top connection 1, the body of rod 2, lower contact 3, connection pin 4
The specific embodiment
Find out the structure of this connected mode by Fig. 2, the two ends of the body of rod 2 are processed a cylindrical hole, the taper thread of one end of top connection 1 and lower contact 3 for being connected with drilling rod up and down, the other end is processed into and the cylinder of the body of rod 2 two ends with diameter, the cylinder of top connection 1 and lower contact 3 is respectively charged in the hole of the body of rod 2, connect with interference fit, guarantee the stability of the joint and the body of rod; On the different cross section of the body of rod and the junction of joint, bore 3 holes then, divide equally by 120 °, each hole is in the position, a hole of axially staggering, its objective is the loss of strength that reduces the body of rod, it is fixing to load onto connection pin 4 in 3 holes, and the body of rod and joint are fixed up, and the junction that will connect pin 4 and joint and the body of rod at last welds, such connected mode just can not fracture in boring procedure.
