Abstract
The utility model discloses a cutting pick for a spiral surfacing protected drilling rib. The cutting pick comprises a hard alloy head, a spiral surfacing layer, a cutting pick head, a cutting pick handle and an annular retainer ring, wherein the hard alloy head is inserted into the top of the cutting pick head in an interference fit way; a spiral surfacing layer is formed on the joint of the hard ally head and the cutting pick head through surfacing; the cutting pick handle is located at the bottom end of the cutting picking head and formed with the cutting pick head into an integrated part; and the annular retainer ring is locked on the middle part of the cutting pick handle, as a layer of highly wearable high-strength material is formed outside the connection joint of the hard alloy head and the cutting pick head of the cutting pick provided by the utility model through the new process of surfacing, the spiral surfacing layer is formed to effectively protect the connection of the main body of the pick head and the alloy, as a result, the wearability of the cutting pick on the cutting pick head is enhanced, the connection of the cutting pick head and the hard alloy head is protected and the service life is prolonged.
Description
Technical field
The utility model relates to engineering machinery stake technical field, particularly relates to a kind of spiral built-up welding protection and digs the rig pick.
Background technology
Along with engineering machinery technology development, the stake hole foundation construction Large diameter such as build at urban construction, highway bridge high level and revolve to dig and bore rotary drilling rig and be widely used.Dig in the brill construction at Large Diameter Rotary, it is one of main bugbear that runs in construction that hard formation creeps into.Usually the hard formation of revolve drilling construction mainly contains riverbed (old course), massif mound and contains the ovum gravel, floats and weathered rock formation etc.At present, creep into these and mainly adopt short augers than hard formation, and its duty and efficient mainly are limited by performance and the life-span that is arranged on pick on drill bit.At present, the pick major part that rotary drilling rig uses is clean steel body and at carbide bit of top solder, this type of rotary drilling rig causes with in use ubiquity welding of pick (or other form connects) phenomenons such as the position is not wear-resisting, integral body is not shock-resistant, alloy cutter head easily comes off the operating efficiency that its application life is short, the replacing number of times is frequent, every meter consumption has greatly seriously reduced rotary drilling rig, and easy-maintaining, do not increase people's labour intensity and cost of production virtually.
The utility model content
The purpose of this utility model is to provide a kind of long service life, lower-cost spiral built-up welding protection to dig the rig pick.
For achieving the above object, technical solution of the present utility model is:
The utility model is that the rig pick is dug in the weldering protection, and it comprises hard alloy head, spiral overlay cladding, cutting pick head, cutting pick handle, annular collar; Described hard alloy head is plugged on the top of cutting pick head in the mode of interference fit, at the spiral overlay cladding of the junction of hard alloy head and cutting pick head built-up welding one deck; Described cutting pick handle is positioned at the bottom of cutting pick head and is integrated member with cutting pick head, on annular collar is connected in the middle part of cutting pick handle.
It is conical that described cutting pick head leading portion is, and back segment is cylindrical, and cutting pick head back segment and cutting pick handle form stepped cylinder.
After adopting such scheme; owing to passing through new technology built-up welding one deck high abrasion, strength materials outside the utility model hard alloy head and cutting pick head connecting portion; form spiral overlay cladding; thereby effectively protect tooth head parent to be connected connection with alloy; make the utility model strengthen the abrasion resistance of pick on the cutting pick head, protected being connected of cutting pick head and hard alloy head; improved application life; and can keep in repair the utility model, make again etc.; make the utility model to reuse, reduced cost of production and simple in structure.In addition, the utility model is equipped with annular collar in the middle part of the tooth handle, can realize at work automatic rotation function.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Description of drawings
Fig. 1 is axonometric drawing of the present utility model;
Fig. 2 is elevation of the present utility model;
Fig. 3 is sectional view of the present utility model;
Fig. 4 is flow sheet of the present utility model.
The specific embodiment
Be that the rig pick is dug in a kind of spiral built-up welding protection as Fig. 1-Fig. 3 the utility model, it comprises hard alloy head 1, spiral overlay cladding 2, cutting pick head 3, cutting pick handle 4, annular collar 5.
It is conical that described cutting pick head 3 leading portions are, and back segment is cylindrical.Described cutting pick handle 4 is positioned at the bottom of cutting pick head 3, and cutting pick head 3 back segments and cutting pick handle 4 form stepped cylinder and be integrated member with cutting pick head 3.
Described hard alloy head 1 is plugged on the top of cutting pick head 3 in the mode of interference fit, at the junction built-up welding one deck spiral overlay cladding 2 of hard alloy head 1 with cutting pick head 3; Annular collar 5 is connected on cutting pick handle 4 middle parts.
As shown in Figure 4, manufacture process of the present utility model:
(1) blanking is prepared;
(2) carry out cutting pick head 3 denticle turning, and according to hard alloy head 1 size drilling cutting pick head 3 heads, leave the heat treatment dimensional requirement;
(3) carry out bulk heat treatmet; Usually denticle section hardness guarantees in the 45HRC left and right;
(4) hard alloy head 1 is inlayed into cutting pick head 3 heads, become interference fit, assembling process can not be damaged hard alloy head 1;
(5) adopt gradually formula bead-welding technology of spiral, built-up welding overall length 30mm left and right, 1 cutting pick head 3 sections of connecing are as the criterion with complete covering protection hard alloy head;
(6) cutting pick handle 4 concave parts of again annular collar 5 being packed into guarantee that it can rotate freely around cutting pick handle 4.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
1. the rig pick is dug in a spiral built-up welding protection, and it is characterized in that: it comprises hard alloy head, spiral overlay cladding, cutting pick head, cutting pick handle, annular collar; Described hard alloy head is plugged on the top of cutting pick head in the mode of interference fit, at the spiral overlay cladding of the junction of hard alloy head and cutting pick head built-up welding one deck; Described cutting pick handle is positioned at the bottom of cutting pick head and is integrated member with cutting pick head, on annular collar is connected in the middle part of cutting pick handle.
