Description
Technical field
It is particularly a kind of to dismantle the special long-drawn-out of transmission pin the utility model is related to a kind of dismounting transmission pin specific purpose tool
Hammer.
Background technology
Transmission pin is one of common fastener in modern machinery and equipment, and effect is to transfer torsion, in incrustation scale, greasy dirt etc.
Under the long duration of action of factor, transmission pin can become rusty extremely with pin hole, so as to cause the shape that transmission pin can not be extracted during maintenance
Condition, existing frequently-used method for dismounting is the connecting rod connection transmission pin that ring flange is first welded with one end, then passes through jack
Top is driven the ring flange of pin connecting rod upper end connection and will be driven pin by being extracted in pin hole, in the process, jack
Very big impulse force can be generated when extracting pin by jacking up, and pin can be caused to fly out, and have very big security risk；It is passed in addition, extracting
The tractive force of dynamic pin application vertically upward, but existing frequently-used this method, can make when extracting transmission pin transmission pin and
The connecting rod unilateral side stress of connection transmission pin can aggravate the abrasion of transmission pin or even can cause transmission due to lateral stressed
The connecting rod fracture of pin and connection transmission pin.
The content of the invention
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of simple in structure, low cost,
The dismounting transmission pin specific purpose tool of safe operation, i.e., a kind of special long-drawn-out hammer for dismantling transmission pin.
The purpose of this utility model can be achieved through the following technical solutions：This simple in structure, low cost, operation peace
The special long-drawn-out hammer of full dismounting transmission pin, it by guide rod, be respectively arranged at guide rod upper and lower ends upper limit position block and under
Limited block, the weight being sleeved on the guide rod between upper limit position block and lower position block and guide rod are located at the end of lower position block one end
The detachable pin connecting screw of head thread connection is formed, and the weight can be slided up and down along guide rod；Described is removable
Unloading formula pin connecting screw can be replaced according to the size of transmission pin diameter, in use, installing suitable detachable
Pin connecting screw makes long-drawn-out hammer consolidate with transmission pin by threaded connection of the detachable pin connecting screw with being driven pin
Fixed, in use, staff's both hands help the upper end of guide rod, another staff quickly lifts weight and slides in shock
Limited block, it is continuous to hit, it will be driven pin until hitting upper limit position block by weight and generating vibration and powerful impact force and loosen
And it extracts.
The special long-drawn-out hammer of this dismounting transmission pin provided by the utility model, simple in structure, low cost, operation peace
Entirely, due to there is staff's both hands to help guide rod, the situation that pin flies out will not occur for when work, can ensure that disassembly process
Safety works at the same time personnel's both hands and helps guide rod that can also prevent long-drawn-out hammer from tilting, weight is made to hit the vibration that upper limit position block generates
With impact force vertically upward, mitigate the abrasion of transmission pin and avoid the detachable pin of transmission pin and connection transmission pin
Connecting screw is lateral stressed and is broken, and the detachable of pin is driven to enterprise safety operation, to extending transmission pin and connection
The service life of pin connecting screw is respectively provided with significance.
Description of the drawings
Fig. 1 is the special long-drawn-out hammer schematic diagram that dismounting provided by the utility model is driven pin；
It is marked in figure：1st, upper limit position block, 2, guide rod, 3, lower position block, 4, detachable pin connecting screw, 5, again
Hammer.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is furtherd elucidate, it should be understood that embodiment is merely to illustrate this reality
With new rather than limitation the scope of the utility model, after the utility model has been read, those skilled in the art are to this practicality
The modification of new various equivalent forms belongs to scope defined herein.
Referring to the drawings, the utility model embodiment provides a kind of simple in structure, low cost, the dismounting trundle of safe operation
The special long-drawn-out hammer of nail, it by steel guide rod 2, be set with and weld and be arranged on the steel of 2 upper and lower ends of steel guide rod
Steel on limited block 1 and steel lower position block 3, the steel guide rod being sleeved between steel upper limit position block 1 and steel lower position block 3
Weight 5 and steel guide rod 2 processed are located at the detachable pin connection of steel of the ends screw connection of 3 one end of steel lower position block
Screw rod 4 is formed, and the steel upper limit position block 1 and steel lower position block 3 are in the form of annular discs；The steel weight 5 can be along steel
Guide rod 2 slides up and down；The detachable pin connecting screw 4 of the steel can carry out more according to the size of transmission pin diameter
It changes, in use, installing the detachable pin connecting screw 4 of suitable steel, passes through the detachable pin connecting screw 4 of steel
Threaded connection with being driven pin makes long-drawn-out hammer be fixed with transmission pin, then is filled between discoid steel lower position block 3 and workpiece
Cushion block consolidates, and prevents hammer inclination of swinging in the course of work, in use, staff's both hands help the upper end of steel guide rod 2,
Another staff quickly lifts steel weight 5 and slides the discoid steel upper limit position block 1 of shock, continuous to hit, you can to pass through steel
Weight 5 processed, which hits the discoid generation of steel upper limit position block 1 vibration and powerful impact force, will be driven pin and loosen and extract.
