Description

Technical Field

[0001] This utility model relates to the field of dryer disassembly and assembly technology, specifically a maintenance workbench applied to the tower tubes of a double-tower dryer. Background Technology

[0002] Air compressor air dryers are crucial sub-equipment in subway vehicle braking systems. They need to reduce the relative humidity of the high-pressure air passing through them to below 35% to ensure reliable and economical braking system operation. When the dryer's drying performance deteriorates, i.e., when the relative humidity of the compressed air is high, the resulting moisture corrosion and freezing hazards can easily lead to pneumatic device malfunctions and premature wear, resulting in a severe decrease in vehicle braking performance or even brake failure. Therefore, it is necessary to replace the desiccant and seals during overhauls. During this process, issues such as loosening or detachment of the tower pipes are unavoidable, requiring timely inspection and repair of the tower pipes.

[0003] The main challenge in overhauling the tower tubes of a dual-tower dryer lies in removing the 65mm hexagonal nuts that extend deep into the bottom of the drying tower. This is because the irregular shape of the drying tower makes it impossible to maintain balance; secondly, the hexagonal nuts extend deep into the bottom of the drying tower, making conventional tools ineffective for the required work; and thirdly, the tower tubes themselves lack effective leverage points, hindering disassembly and reassembly. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a maintenance workbench for the tower tubes of a double-tower dryer. It can be quickly fixed to the dryer body and is equipped with a sleeve and rocker arm for disassembly and assembly, thereby improving maintenance efficiency and reducing labor intensity.

[0005] The technical solution provided by this utility model is as follows: a maintenance workbench for the tower tubes of a double-tower dryer, including a fixed base, a sleeve for removing nuts, and a rocker arm for removing tower tubes. A fixed clamp is provided on one side of the fixed base, and a movable clamp that is movably connected to the fixed base is provided on the other side of the fixed base. Arc-shaped slots are symmetrically provided on the sides of the fixed clamp and the movable clamp that are close to each other, and a clamping part for fixing the dryer is formed between the two arc-shaped slots.

[0006] Furthermore, a fixing plate is provided at the end of the fixed base away from the fixing clamp, and a screw hole is provided in the middle of the fixing plate. A rotating threaded rod is threadedly connected to the screw hole. One end of the rotating threaded rod is rotatably connected to the movable clamp, and the other end of the rotating threaded rod is provided with a handle.

[0007] Furthermore, the bottom of the sleeve is provided with a first opening, which is adapted to the shape and size of the hexagonal nut at the bottom of the dryer. The top of the sleeve is provided with a second opening, which is adapted to the shape and size of the torque wrench. The torque wrench drives the sleeve to rotate in order to install or remove the hexagonal nut at the bottom of the dryer.

[0008] Furthermore, the length of the sleeve is greater than the length of the drying tower body, and the sleeve is made of stainless steel.

[0009] Furthermore, the two arc-shaped slots are made of resin.

[0010] Furthermore, the rocker arm has a circular cross-section, and its diameter is matched with the diameter of the air hole in the dryer tower tube. The rocker arm is inserted into the air hole in the tower tube and rotated to realize the assembly and disassembly of the tower tube.

[0011] Furthermore, the joystick is made of aluminum.

[0012] Furthermore, weight-reducing holes are provided on both the front and rear sides of the fixed base.

[0013] The beneficial effects of this utility model are:

[0014] (1) The drying tower is clamped by a fixed clamp and a movable clamp without causing damage to the drying tower body. The fixed base and clamp ensure that the drying tower will not move in any form during operation, thus avoiding overturning.

[0015] (2) Insert the sleeve into the bottom of the dryer to fit the hexagonal nut, and then use a torque wrench to disassemble and assemble the hexagonal nut. It is convenient to use and saves time and effort.

[0016] (3) The matching custom aluminum rocker can be used to disassemble and assemble the tower tube through the air hole of the tower tube without damaging the tower tube body.

[0017] This utility model has a reasonable design and simple structure, enabling the disassembly and assembly of components such as dryer tower tubes. It avoids all the potential hazards that existed before, and will not cause any negative damage to the components themselves or the workbench. It ensures that operators can complete the relevant operations conveniently and quickly, thus improving work efficiency. Attached Figure Description

A fixing clamp 4 is provided on one side of the fixed base 1, and a movable clamp 5, movably connected to the fixed base 1, is provided on the opposite side of the fixed base 1. Arc-shaped slots are symmetrically arranged on the sides of the fixed clamp 4 and the movable clamp 5 that are close to each other, forming a clamping part for fixing the dryer. The fixing clamp 4 is fixed to the fixed base 1.

[0024] A fixing plate 6 is provided at the end of the fixed base 1 away from the fixing clamp 4. A screw hole is provided in the middle of the fixing plate 6, and a rotating threaded rod 7 is threaded into the screw hole. One end of the rotating threaded rod 7 is rotatably connected to the movable clamp 5, and the other end of the rotating threaded rod 7 is provided with a handle 8. Specifically, a connecting block is fixed on the outer wall of the movable clamp 5, and the connecting block is rotatably connected to the rotating threaded rod 7.

[0025] The sleeve 2 has a first opening at its bottom, which is adapted to the shape and size of the hexagonal nut at the bottom of the dryer. The sleeve 2 has a second opening at its top, which is adapted to the shape and size of a torque wrench. The sleeve is rotated by the torque wrench to install or remove the hexagonal nut at the bottom of the dryer. The length of the sleeve 2 is greater than the length of the drying tower body, and the sleeve 2 is made of stainless steel.

[0026] The rocker arm 3 has a circular cross-section, and its diameter is matched with the diameter of the air hole in the tower tube.
