Description

Be applied to maintenance workstation of two tower desicators tower pipe Technical Field The utility model relates to the technical field of disassembly and assembly of dryers, in particular to an overhaul workbench applied to a tower tube of a double-tower dryer. Background The air dryer of the air compressor is an important sub-device in a metro vehicle braking system, and the relative humidity of the passing high-pressure air needs to be reduced to below 35 percent so as to ensure that the braking system can work reliably and economically. When the drying performance of the dryer is reduced, i.e. when the relative humidity of the compressed air is high, the risk of corrosion and freezing of the moisture caused by it is liable to cause malfunctions and premature wear of the pneumatic device, thus severely degrading or even failing the braking performance of the vehicle. Thus requiring replacement of the desiccant and seal during the repair process. In the process, the conditions of loosening, falling off and the like of the tower tube inevitably occur, and the tower tube needs to be overhauled in time aiming at the conditions. The main difficulty of the maintenance work of the double-tower dryer tower pipe is that a 65mm fixed hexagonal nut penetrating into the bottom of the drying tower is taken down. In the process, the drying tower body is irregular and cannot be balanced, the hexagonal nut penetrates into the bottom of the drying tower, the conventional tool cannot complete maintenance requirements, and the tower pipe body has no effective acting point, so that the drying tower can be disassembled. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides the overhaul workbench applied to the tower pipe of the double-tower dryer, which can be quickly fixed with the dryer body, is provided with the sleeve and the rocker for dismounting work, improves the overhaul efficiency and reduces the labor intensity. The technical scheme includes that the overhaul workbench applied to the tower tube of the double-tower dryer comprises a fixed base, a sleeve for disassembling nuts and a rocker for disassembling the tower tube, wherein a fixed clamp is arranged on one side of the fixed base, a movable clamp movably connected with the fixed base is arranged on the other side of the fixed base, arc-shaped clamping grooves are symmetrically formed in one sides, close to each other, of the fixed clamp and the movable clamp, and a clamping part for fixing the dryer is formed between the two arc-shaped clamping grooves. Further, the unable adjustment base keeps away from the one end of mounting fixture and is provided with the fixed plate, the screw has been seted up at the middle part of fixed plate, threaded connection has rotatory threaded rod in the screw, the one end and the movable fixture rotation of rotatory threaded rod are connected, the other end of rotatory threaded rod is provided with the handle. Further, the bottom of telescopic is provided with first opening, first opening and the shape and the size looks adaptation of desicator bottom hexagon nut, telescopic top is provided with the second opening, second open-ended shape, size and moment spanner looks adaptation drive the sleeve rotation with dismouting desicator bottom hexagon nut through the moment spanner. Further, the length of the sleeve is larger than that of the cylinder body of the drying tower, and the sleeve is made of stainless steel. Further, the two arc-shaped clamping grooves are made of resin. Further, the cross section of rocker is circular, and the diameter of rocker and the diameter looks adaptation of desicator tower pipe gas pocket, rocker insert rotatory in the tower pipe gas pocket in order to realize the dismouting of tower pipe. Furthermore, the rocker is made of aluminum. Furthermore, the front side and the rear side of the fixed base are provided with lightening holes The utility model has the beneficial effects that: (1) The drying tower is clamped by the fixed clamp and the movable clamp, the damage to the drying tower body is avoided, and the fixed base and the clamp enable the drying tower not to move in any form in the operation process, so that the overturning is avoided; (2) The socket penetrates into the bottom of the dryer to be matched with the hexagonal nut, and then the hexagonal nut is disassembled and assembled through the torque wrench, so that the dryer is convenient to use, and time and labor are saved; (3) The matched custom-made aluminum rocker can be used for disassembling and assembling the tower pipe by means of the tower pipe air holes, and the tower pipe body cannot be damaged. The utility model has reasonable design and simple structure, realizes the disassembly and assembly of the components such as the tower tube of the dryer, can avoid all hidden dangers existing before, can not cause negative damage to the components and the workbench, ensures that operators can
