Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and 3, a special tool for disassembling and assembling an HJS63A type martial feeding oiling joint is characterized in that a first vertical rod 2 and a second vertical rod 3 are integrally welded at one end of a main rod 1 of the special tool, the first vertical rod 2 and the second vertical rod 3 are positioned on the same side of the main rod 1, the diameters of the first vertical rod 2 and the second vertical rod 3 correspond to a gap between a joint body assembly 5 and a guide frame assembly 6, and the diameters of the first vertical rod 2 and the second vertical rod 3 are slightly smaller than the gap; one end of the first vertical rod 2 is integrally welded at the end of the main rod 1, the other end of the first vertical rod 2 is provided with a bent convex part 21 forwards (at the left side shown in figure 1 or 2), and the length L of the convex part 21 corresponds to the depth of the tooth gap of the joint body assembly 5 and is less than the depth; the convex part 21 is arranged to be bent, so that the convex part 21 can be clamped and taken out of a gap between the convex part 21 and the joint body assembly 5 arranged on the lower portion of the butt joint disc 7, and the distance between the first vertical rod 2 and the second vertical rod 3 is smaller than the diameter of the guide frame assembly 6. The maximum distance between first montant 2 and the second montant 3 is less than the diameter of leading truck assembly 6, and first montant 2 and the equal centre gripping of second montant 3 are on leading truck assembly 6 promptly, and at this moment, main part pole 1 separates leading truck assembly 6 for a side area big, and the state that the other side area is little is favorable to twisting soon. The minimum distance between the first upright 2 and the second upright 3 is such that the protrusion 21 can snap into the gap between the teeth of the joint body assembly 5, in order to ensure that the special tool can provide the force for rotating the joint body assembly 5. The special tool is subjected to grinding and polishing treatment to enable the outer surface to be smooth, particularly the contact part with the joint, so that the joint is not easy to damage.
The distance D between the first vertical bar 2 and the second vertical bar 3 is 60-75 mm. Preferably 69mm, when the distance D between the first vertical rod 2 and the second vertical rod 3 is 69mm, the length L of the protruding portion 21 is set to 3.6mm, so that the protruding portion 21 can be flexibly inserted into and taken out from the gap between the joint body assembly 5, and the operation is convenient.
The other end of the main body rod 1 is provided with a handle 4. Is convenient for holding and applying force to the hand. The handle 4 is arranged in an open tubular shape, and a cord is threaded in the tube, so that the tool can be conveniently hung and stored.
The contact part of the first vertical rod 2 and the second vertical rod 3 and the guide frame assembly 6 is wrapped with a protective sleeve. The lag can be for the material that any can realize the protection now, for example rubber pipe box, silica gel pipe box etc. mainly used protects first montant 2 and second montant 3 and the contact department of leading truck assembly 6, avoids the rigidity contact, and the butt joint produces wearing and tearing, has increased the frictional force of contact department simultaneously. The protective sleeve can also be arranged in a net shape, so that the friction force is increased.
Example 2
On the basis of embodiment 1, in this embodiment, a positioning block 31 is disposed at the lower end of the second vertical rod 3. The diameter of the positioning block 31 is slightly larger than that of the second vertical rod 3, and the positioning block 31 is more beneficial to clamping and positioning the second vertical rod 3 and the guide frame assembly 6. The two ends of the handle 4 are arranged to be closed arc structures, so that the handle is convenient to hold by hands.
When the special tool is used for splitting a joint, a first vertical rod 2 and a second vertical rod 3 are firstly connected on a guide frame assembly 6 in a clamped mode, at the moment, a protruding portion 21 of the first vertical rod 2 is clamped in a gap between 5 teeth of a joint body assembly arranged on the lower portion of a butt joint disc 7, a contact portion of the second vertical rod 3 and the guide frame assembly 6 forms a fulcrum of a lever, the distance between the first vertical rod 2 and the second vertical rod 3 is a resistance arm of the lever, the distance between the second vertical rod 3 and a handle 4 of a main body rod 1 is a power arm, a labor-saving lever is formed, the main body rod 1 is rotated clockwise, the rotary joint body assembly 5 capable of being relaxed is adopted, the guide frame assembly 6 is popped out, and the splitting of the guide frame assembly 6 and the joint body assembly 5 is completed.
When the special tool is used for disassembling the joint, the disassembling process of the special tool is to use the special tool to directly disassemble the guide frame assembly 6 and the joint body assembly 5, and the connecting parts of all structures are not required to be disassembled. Compare in normal split flow, practiced thrift a plurality of screw on the split stainless steel sheath clamp plate, pull down two stainless steel sheath clamp plates, then shell rubber protective sheath 8 with the hand, unscrew a plurality of bolt on the joint body assembly 5 again, take off docking tray 7, reuse the split leading truck assembly 6 and the 5 processes of joint body assembly of docking seat. Namely the utility model discloses a dismouting HJS63A type is wu advances to refuel and connects specialized tool split step is simple, quick, and can not damage the joint, has improved work efficiency.
Example 3
By comparing the special tool with the existing splitting method, 10 connectors are overhauled according to the month, and the total time is counted, which is shown in figure 4. As can be seen from FIG. 4, the maintenance time of each joint is shortened to 2 minutes on average, and the working efficiency is greatly improved. Meanwhile, due to the fact that the splitting step is simplified, oil loss is reduced along with the oil loss in the process of overhauling the oil filling joint, and the oil loss in the process of overhauling each oil filling joint is reduced to one tenth.
