The drilling rod retainer of the utility model diaphragm wall rig, by adopting semicircle neck bush and semicircle external bushing, bore the increase of pick workload along with rig, when liner wear surpasses the technical requirements scope, only need unclamp the fastening screw screw bolt and nut of retainer, change and carry out the replacing of semicircle neck bush and semicircle external bushing easily, and needn't change whole retainer, the care and maintenance cost of equipment is reduced greatly, effectively improved construction operation efficient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the drilling rod retainer of the utility model diaphragm wall rig;
Fig. 2 is the front view of the drilling rod retainer of the utility model diaphragm wall rig;
Fig. 3 is the vertical view of the drilling rod retainer of the utility model diaphragm wall rig;
Fig. 4 is that the A-A of Fig. 2 is to sectional view.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of drilling rod retainer of diaphragm wall rig, comprise drilling rod 1, neck bush pair 2, external bushing pair 3, retainer 4, bolt 5 and nut 6, neck bush pair 2 places the installation site of drilling rod 1 cylindrical, welding position block 11 on drilling rod 1 cylindrical, its distance is consistent with the length of neck bush pair 2; Neck bush pair 2 is made up of the semicircle neck bush 21 of two symmetries, and the two ends of its upper and lower end face all have rectangular notch, and rectangular notch is aimed at position block 11; In the groove of secondary 2 cylindricals of neck bush external bushing pair 3 is installed, external bushing pair 3 is made up of the semicircle external bushing 31 of two symmetries, and the two ends of its upper and lower end face all have rectangular notch, and rectangular notch is aimed at limited block 47; The semicircle neck bush 21 of two symmetries and semicircle external bushing 31 are installed the back respectively and are formed neck bush secondary 2 and external bushing pair 3, and certain radial clearance is arranged between the two, are convenient to store lubricating grease; Semicircle neck bush 21 and semicircle external bushing 31 differ 90 ° staggered installation of angle along the radial direction of drilling rod 1; Installation frame body pair 4 in the groove of bushing pair 3 cylindricals outside; Retainer 4 is made up of the support body 41 of two symmetries, with bolt 5 and nut 6 support body 41 is fixed together; Support body 41 two ends are rectangular slab 42, and the centre is semicircle cylindrical shell 43 and connecting plate 44, and the centre distance between the centre distance between the semicircle cylindrical shell 43 and the drilling rod 1 of diaphragm wall rig is consistent; Mutually perpendicular straight gusset 45 and horizontal bar plate 46 are arranged on the outer edge surface of support body 41; The limited position of the upper and lower end face of support body 41 first circular cylinder bodies 43 piece 47;
