Abstract
The utility model discloses a wrench special for a thermocouple protective sleeve of a locomotive diesel engine, which is used for assembling and disassembling the thermocouple protective sleeve. One end of a hollow pipe capable of accommodating the thermocouple protective sleeve is provided with an internal hexagonal sleeve, and the other end of the hollow pipe is provided with an internal tetragonal joint which is used for assembling a common quick operation wrench; and an annular groove is formed on the internal tetragonal joint. By the wrench, the interference of surrounding barriers and the thermocouple protective sleeve can be avoided; threads are loosened and fastened in a quick swinging mode, and a user is not required to squat on a rocker arm shaft seat of the diesel engine but stands on a walking platform for operation when the wrench is operated, so that operation gestures are thoroughly improved; and the user can be far away from a diesel engine exhaust pipe with a high temperature, can be prevented from falling off the diesel engine and cannot be scalded by the exhaust pipe easily, so that working efficiency is greatly improved, and insufficient tightening torque is ensured.
Description
Technical field
The utility model relates to technical field of tools, is a kind of special spanner that is used for dismounting diesel engine of diesel locomotive thermocouple well specifically.
Background technology
In the diesel engine of locomotive maintenance process; Because thermocouple well is installed in the small space of diesel exhaust gas house steward, exhaust branch pipe, exit branch and rocker arm support composition; And outer six sides that tighten thermocouple well contact with exhaust branch pipe in the middle; Must squat during dismounting and carry out the dismounting operation on the thermocouple well using common open-end wrench or monkey wrench tiltedly to be stuck on the rocker shaft bed, spanner and thermocouple well itself reaches barrier severe interference on every side; Simultaneously, during dismounting, the inconvenience of maintenance personal's work posture, inefficiency has the danger of falling from diesel engine; In addition, temperature higher (diesel exhaust gas house steward temperature is above 500 ℃) during diesel engine work is scalded the operator easily.Often go out when diesel engine is worked because of the screw-down torque deficiency causes thermocouple well in the practical operation, the thermocouple of going out causes certain security threat to the operating personnel.
Summary of the invention
For overcoming the deficiency of prior art, the goal of the invention of the utility model is to provide a kind of diesel engine of locomotive thermocouple well special spanner, in convenient use, handling safety, increases work efficiency.
For realizing above-mentioned purpose, an end of the hollow tube of the held thermocouple well of the utility model has interior six square sockets, and the interior square joint of the other end is used for assembling fast wrench commonly used, on the interior square joint annular groove is arranged.
The utility model compared with prior art utilizes this spanner to avoid the barrier on every side and the interference of hot sheath itself, adopts the mode of swing fast to carry out the operation of degree of tightness screw thread; Need not squat on diesel engine rocker shaft brackets during operation; Go up operation but stand in to walk on stage, work posture is thoroughly improved, can be away from the Diesel Engine Exhaust Pipe with higher temperature; Do not have the danger of falling from diesel engine; Also be difficult for being deflated pipe and scald, improved operating efficiency greatly, and guaranteed enough screw-down torques.
Description of drawings
Accompanying drawing is the structural representation sketch of the utility model.
The specific embodiment
Shown in accompanying drawing; One end that can hold the stainless steel hollow tube 3 of thermocouple well has interior six square sockets 1; Can block outer six sides of thermocouple well below; The thrust shaft shoulder 2 of interior six square sockets 1 is used to transmit torsion and realizes axial location and transmit axial force that hollow tube 3 can be used as the protection tube of thermocouple and uses; The interior square joint 4 of hollow tube 3 other ends is connected with fast wrench; On the interior square joint 4 annular groove 5 is arranged; When being used, can play and prevent to get loose effect with fast wrench commonly used; Fast wrench is meant commonly used a kind of 1/2, and " the fast wrench of combined type of the square joint ratchet of 12.5mm and switching-over joint switch, the effect of switching-over joint switch is when spanner is stuck in extreme position, can conveniently withdraw from.
