Description
Technical Field
[0001] This invention relates to the technical field of condensate pumps, and more particularly to a tool for dismantling condensate pump couplings. Background Technology
[0002] The pump-side coupling of the condensate pump has an transition fit with the journal. Routine maintenance requires disassembling the coupling by heating it. However, this method has several drawbacks. First, if the heating temperature is not properly controlled, the coupling may not heat evenly, making it impossible to disassemble even after the journal has heated up. Second, due to the large outer diameter of the coupling and the small diameter of the coupling pin hole, the traditional method of using a puller and heating cannot be used to disassemble the coupling. Therefore, a coupling disassembly tool is needed to facilitate the disassembly of the coupling using a puller and heating. Summary of the Invention

[0033] The disassembly mechanism 100 includes a coupling 101 and a disassembly part 102 disposed on the coupling 101. The coupling 101 and the disassembly part 102 are connected by a bolt part 103.
[0034] The heating mechanism 200 includes a rotating part 201 disposed on the disassembly part 102, a first heating part 202 disposed on the rotating part 201, a second heating part 203 disposed on the rotating part 201, and a power part 204 disposed on the first heating part 202; and,
[0035] The latching mechanism 300 includes a first latching part 301 disposed on the first heating part 202, a second latching part 302 disposed on the second heating part 203, and a third latching part 303 disposed on the second heating part 203.
[0036] During use, the disassembly part 102 is inserted into the coupling 101, and the disassembly part 102 is fixed to the coupling 101 by the bolt part 103. The first heating part 202 and the second heating part 203 are installed on the rotating part 201. The third locking part 303 is pulled to release the limiting of the second locking part 302. The second locking part 302 and the first locking part 301 are in close contact, thereby limiting and fixing the first heating part 202 and the second heating part 203. The power unit 204 is started to drive the first heating part 202 and the second heating part 203 to rotate. The second heating part 203 heats the coupling 101 evenly. When the temperature of the coupling 101 is maintained above 180°C, the three claws of the hydraulic puller are fixed to the edge of the disassembly part 102. The hydraulic puller push rod is pressed against the shaft center of the coupling 101. The hydraulic puller is slowly applied to push the coupling 101 out from the journal position.
[0037] Example 2
[0038] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the disassembly part 102 includes a base 102a disposed on the outer periphery of the coupling 101 and a flange 102b disposed on the base 102a.
[0039] Preferably, the base 102a is made of a steel plate with a diameter of 650mm and a thickness of 30mm. Four round holes with a diameter of 32mm are cut according to the position of the pin of the coupling 101. The flange 102b is a DN200 flange.
[0040] The bolt part 103 includes a screw 103a disposed on the coupling 101, a stop piece 103b disposed on the screw 103a, and a threaded sleeve 103c disposed on the base 102a and adapted to the screw 103a.
[0041] The rotating part 201 includes an annular slip ring 201a disposed on the base 102a and a rotating slider 201b disposed within the annular slip ring 201a.
[0042] Preferably, the outer surface of the annular slip ring 201a is provided with an annular groove, and the rotating slider 201b is slidably connected to the inner surface of the annular groove.
[0043] The first heating section 202 includes a first arc-shaped heating frame 202a disposed on the rotating slider 201b, and a first lattice layer 202b disposed on the first arc-shaped heating frame 202a.
[0044] Preferably, the first arc-shaped heating frame 202a is semi-annular, and the first lattice layer 202b reflects the heat irradiated on the first arc-shaped heating frame 202a onto the coupling 101, thereby increasing the heat utilization rate and making the coupling 101 more uniformly heated.
[0045] The second heating unit 203 includes a second arc-shaped heating frame 203a disposed on the rotating slider 201b, a second lattice layer 203b disposed on the second arc-shaped heating frame 203a, a heating groove 203c disposed on the second arc-shaped heating frame 203a, an electric heating tube 203d disposed inside the second arc-shaped heating frame 203a, and a battery 203e disposed on the second arc-shaped heating frame 203a and connected to the electric heating tube 203d.
[0046] Preferably, the second lattice layer 203b allows heat to be more concentrated on the coupling 101, increasing heating efficiency. The electric heating tube 203d is made of quartz tube and is placed inside the second arc-shaped heating frame 203a to protect the electric heating tube 203d and prevent workers from accidentally touching the electric heating tube 203d. An anti-touch net can be installed on the heating tank 203c.
[0047] The power unit 204 includes an electric motor 204a disposed on the first arc-shaped heating frame 202a, a rotating gear 204b disposed on the electric motor 204a, and a rotating gear ring 204c disposed on the base 102a and adapted to the rotating gear 204b.
[0048] The remaining structure is the same as that in Example 1.
[0049] During use, the base 102a is fitted onto the coupling 101, and the screw 103a is threaded through the pin hole of the coupling 101 and threaded into the threaded sleeve 103c, thereby fixing the base 102a onto the coupling 101. The rotating slider 201b on the first arc-shaped heating frame 202a and the rotating slider 201b on the second arc-shaped heating frame 203a are placed into the annular slip ring 201a. The third locking part 303 is pulled to release the restriction on the second locking part 302, and the second locking part 302 comes into close contact with the first locking part 301, thereby connecting the first arc-shaped heating frame 202a and the second arc-shaped heating frame 203a. The heating frame 203a is fixed in place. The motor 204a is started, which drives the rotating gear 204b to rotate. Due to the setting of the rotating gear ring 204c, the rotation of the rotating gear 204b drives the motor 204a to make the first arc-shaped heating frame 202a drive the rotating slider 201b to rotate along the annular slip ring 201a. At the same time, the first arc-shaped heating frame 202a drives the first locking part 301 to rotate the second locking part 302. The second locking part 302 drives the second arc-shaped heating frame 203a to rotate, and the electric heating tube 203d is turned on, so that the electric heating tube 203d heats the coupling 101 evenly.
[0050] Example 3
[0051] Reference Figure 5 , 6This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the first snap-fit portion 301 includes a low extension plate 301a disposed on the first arc-shaped heating frame 202a, a first snap-fit block 301b disposed on the low extension plate 301a, a first arc surface 301c disposed on the first snap-fit block 301b, and a second arc surface 301d disposed on the first snap-fit block 301b.
[0052] Preferably, the first latching block 301b is a semi-circular block, and the first arc surface 301c provides space for the second latching part 302 to rotate, so that the second latching part 302 can enter the second arc surface 301d. At the same time, it can increase the stability of the connection between the first latching block 301b and the second latching part 302. The second arc surface 301d is adapted to the arc surface of the second latching block 302e, so that the second latching block 302e can be in close contact with the second arc surface 301d.
[0053] The second locking part 302 includes a rotating rod 302a disposed on the second arc-shaped heating frame 203a, a high extension plate 302b disposed on the rotating rod 302a, a rotating handle 302c disposed on the high extension plate 302b, a torsion spring 302d disposed on the rotating rod 302a, a second locking block 302e disposed on the high extension plate 302b, and a first L-shaped slot 302f disposed on the second locking block 302e.
[0054] Preferably, the rotating rod 302a is rotatably mounted on the second arc-shaped heating frame 203a, and the high extension plate 302b is misaligned with the low extension plate 301a to ensure the normal rotation of the high extension plate 302b. One end of the torsion spring 302d is fixedly connected to the second arc-shaped heating frame 203a, and the other end of the torsion spring 302d is fixedly connected to the outer surface of the rotating rod 302a. The second locking block 302e is on the same horizontal plane as the first locking block 301b, and the second locking block 302e is a circular block.
[0055] The third locking part 303 includes a slide plate 303a disposed on the second arc-shaped heating frame 203a, a locking slider 303b disposed in the slide plate 303a, a return spring 303c disposed in the slide plate 303a, a third locking block 303d disposed on the locking slider 303b, a second L-shaped locking groove 303e disposed on the third locking block 303d, and a lifting handle 303f disposed on the third locking block 303d.
[0056] Preferably, the third locking block 303d is a circular block, and the openings of the first L-shaped slot 302f and the second L-shaped slot 303e are opposite.
[0057] The remaining structure is the same as that in Example 2.
[0058] During use, when it is necessary to limit and fix the first arc-shaped heating frame 202a and the second arc-shaped heating frame 203a, pulling the lifting handle 303f causes the third locking block 303d to drive the locking slider 303b to move along the slide plate 303a. The third locking block 303d drives the second L-shaped slot 303e away from the second locking block 302e, thereby releasing the limitation on the first L-shaped slot 302f. The elastic force of the torsion spring 302d drives the rotating rod 302a to rotate. The rotating rod 302a drives the high extension plate 302b to make the arc surface of the second locking block 302e match the first arc surface 301c. The mutual hook and lock of the second locking block 302e and the first locking block 301b fixes the first arc-shaped heating frame 202a and the second arc-shaped heating frame 203a. The heating frame 203a is fixed in a limited position. When it is necessary to release the fixed position, the rotating handle 302c is rotated to drive the high extension plate 302b to rotate the rotating rod 302a. The rotation of the rotating rod 302a drives the torsion spring 302d to tighten. At the same time, the high extension plate 302b drives the second locking block 302e to rotate. The arc surface of the second locking block 302e presses against the arc surface of the third locking block 303d, causing the third locking block 303d to move. The third locking block 303d drives the locking slider 303b to press against the return spring 303c, causing the return spring 303c to contract. When the first L-shaped slot 302f matches the second L-shaped slot 303e, the elastic force of the return spring 303c pushes the locking slider 303b to limit the second locking block 302e to the third locking block 303d.
