Description
Technical Field
The utility model relates to a machinery dimension protects instrument, concretely relates to telescopic joint quick detach instrument for hydraulic pressure draws horse.
Background
The hydraulic puller moves forward directly by the oil pressure starting rod, so the pushing rod does not rotate. The hook claw seat can directly adjust the distance of advancing and retreating along with the screw thread, when in operation, the hydraulic starting rod moves forwards only by swinging the handle forwards and backwards by a small amplitude, the hook claw correspondingly retreats, and the pulled object is pulled out.
The power plant needs to generate power continuously, when equipment breaks down, it is very important to overhaul and recover in time, and maintenance tool convenient to use is the important link of guaranteeing maintenance efficiency and quality better. When a motor in equipment breaks down and is maintained, a coupler and a bearing are pulled out by a hydraulic puller frequently. However, in actual operation, the existing conventional hydraulic puller has insufficient effective extension distance due to the overlong coupler, and cannot adapt to the lengths of various large couplers and bearings. When the puller is used for disassembly, the puller cannot be pulled out at one time, and can be pulled out completely only by multiple times of auxiliary positioning. And the length of the propelling rod is increased on the hydraulic puller, so that the hydraulic puller is inconvenient to use, and the weight of the hydraulic puller is increased. Therefore, a quick-release tool for an expansion joint of a hydraulic puller is needed, which can expand and contract according to the length of a coupling and other devices, is convenient to carry and use, and does not increase the weight of the hydraulic puller.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned prior art, the utility model aims at providing an expansion joint quick detach instrument for hydraulic pressure draws horse. The device is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an expansion joint quick-dismantling tool for a hydraulic puller, which comprises a first expansion joint, a second expansion joint and a bottom rod which are connected in turn through screw threads; threads are arranged on the outer wall of the first telescopic joint, the outer wall and the inner wall of the second telescopic joint and the inner wall of the bottom rod, and the lengths of the threads are equal; the outer wall of the first telescopic joint is connected with the inner wall of the second telescopic joint through threads, and the outer wall of the second telescopic joint is connected with the inner wall of the bottom rod through threads; the top of the first telescopic joint is provided with a push rod connecting ring, four fastening valves are arranged on the outer wall of the push rod connecting ring at equal intervals, the fastening valves penetrate through the outer wall and the inner wall of the push rod connecting ring, and the fastening valves are connected with the push rod connecting ring through threads. The diameter of the bottom rod is larger than that of the second telescopic joint, and the diameter of the second telescopic joint is larger than that of the first telescopic joint.
Preferably, the top of the second telescopic joint is provided with a check ring, and the first telescopic joint is in threaded connection with the check ring. The stop ring can prevent the second expansion joint from completely entering the bottom rod when contracting, and the situation that the second expansion joint cannot extend is avoided.
Preferably, four fastening holes are arranged on the outer wall of the anti-retraction ring at equal intervals, and penetrate through the outer wall and the inner wall of the anti-retraction ring. When the first telescopic joint extends to the maximum length, because the diameter of the first telescopic joint is smaller than that of the second telescopic joint, in order to ensure the stability of the hydraulic puller during working, the fastening bolts are arranged on the four fastening holes, so that the stability when the telescopic joint quick-detaching tool reaches the maximum length is ensured, and the telescopic joint quick-detaching tool does not shake during pulling.
Preferably, the lower part of the bottom rod is provided with a thread. When the bottom rod is not in accordance with the size of the coupling, a threaded ring (similar to a nut) with the diameter corresponding to that of the coupling can be connected to the lower part of the bottom rod through threads. Make the utility model discloses an expansion joint quick detach instrument can be applicable to all kinds of equipment.
The utility model has the advantages that:
the utility model discloses can carry out the flexible regulation of length according to the length of devices such as shaft coupling, adjust through the screw thread and can realize the fine tuning of microspur, can not produce harm such as horse is drawn to shaft coupling, bearing or hydraulic pressure. The utility model discloses portable, simple to operate to can be applicable to the different hydraulic pressure of various sizes and draw horse and equipment.
