Description

Technical Field

[0001] This utility model relates to the field of maintenance tooling technology for hydropower plants, and in particular to an emergency door pulley axle clamping assembly and disassembly device. Background Technology

[0002] The emergency door pulleys are installed on both sides of the emergency door via wheel axle 1. The pulleys make the emergency door easier to open and close. The cooperation between the pulleys and the track reduces the shaking of the emergency door. The rolling friction of the pulleys reduces wear and noise, reduces wear on emergency door components, and extends the overall service life. In order to ensure the normal opening and closing of the emergency door, the wheel axle needs to be removed for inspection and maintenance during major overhauls.

[0003] Because major overhauls are typically spaced out over a long period, axle 1 is corroded. (See attached image) Figure 8 Although a threaded hole 4 is provided in the middle of the large end of the axle 1, the diameter of the threaded hole 4 is only M16, which is relatively small. Furthermore, due to corrosion, the threads are damaged. After re-tapping with a tap, when the axle 1 is pulled outwards with an M16 long screw installed, the threads in the threaded hole 4 are prone to being pulled out, making it impossible to remove the axle 1. If the long screw is directly welded to the axle 1, a large amount of heat will be generated during welding, causing the axle 1 to heat up and expand, making it even more difficult to remove. To solve this problem, the technicians designed an emergency door pulley axle clamping assembly and disassembly device using the limiting platforms 2 on both sides of the large end of the axle 1.

By cutting a groove on the limiting platform, the clamping block on the clamping plate is inserted into the groove. Then, the two clamping plates are limited by the limiting plate, so that the clamping plates are clamped on the limiting platform. The pulling block is connected to the two clamping plates. Pulling the pulling block outward can remove the axle.

[0005] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: An emergency door pulley axle clamping assembly includes a clamping plate, a limiting plate, and a tension block. One end of the clamping plate is provided with a vertically extending locking block, and the other end is provided with a tension hole. There are two clamping plates, and the locking blocks on the two clamping plates are opposite each other. The locking blocks are used to engage with the grooves at the ends of the axles. The limiting plate is provided with two limiting holes. The ends of the two clamping plates with tension holes pass through the two limiting holes respectively, so that the two clamping plates are respectively clamped on the limiting platforms on both sides of the ends of the axles. The tension block passes through the tension holes on the two clamping plates.

[0006] The limiting plate has a first through hole in the middle; in use, the threaded end of the positioning screw passes through the first through hole and is then screwed into the threaded hole at the end of the wheel axle for fixation.

[0007] One side of the tension block is provided with a limit groove at the position of the corresponding tension hole. When the tension block is subjected to outward force, the clamping plate is inserted into the limit groove.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0031] Example 1: See Figure 1-5 An emergency door pulley axle clamping assembly includes a clamping plate 10, a limiting plate 20, and a tension block 30. One end of the clamping plate 10 is provided with a vertically extending locking block 11, and the other end is provided with a tension hole 12. There are two clamping plates 10, and the locking blocks 11 on the two clamping plates 10 are opposite each other. The locking blocks 11 are used to lock into the groove 3 at the end of the axle 1. The limiting plate 20 is provided with two limiting holes 22. The ends of the two clamping plates 10 with tension holes 12 pass through the two limiting holes 22 respectively, so that the two clamping plates 10 are respectively clamped on the limiting platforms 2 on both sides of the end of the axle 1. The tension block 30 passes through the tension holes 12 on the two clamping plates 10. This utility model cuts a groove 3 on the limiting platform 2 so that the locking block 11 on the clamping plate 10 can be inserted into the groove 3. Then, the limiting plate 20 limits the two clamping plates 10, so that the clamping plates 10 are clamped on the limiting platform 2. The pulling block 30 is connected to the two clamping plates 10. Pulling the pulling block 30 outward can remove the wheel axle 2.

[0032] In use, the limiting platform 2 is cut and slotted by using an angle grinder with a grinding wheel to create a groove 3.

[0033] See Figure 3 , 6 The limiting plate 20 has a first through hole 21 in the middle. When in use, the threaded end of the positioning screw 23 passes through the first through hole 21 and is then screwed into the threaded hole 4 at the end of the wheel axle 1 to fix the limiting plate 20 to the wheel axle 1. After the limiting plate 20 is fixed, the clamping plate 10 inserted in the limiting holes 22 at both ends of the limiting plate 20 is also limited. When the wheel axle 1 is disassembled, the clamping plate 10 will not fall off the wheel axle 1.

[0034] See Figure 4 A limiting groove 31 is provided on one side of the tension block 30 at the position corresponding to the tension hole 12. When the tension block 30 is subjected to outward force, the clamping plate 10 is inserted into the limiting groove 31, thereby limiting the tension block 30 and the clamping plates 10 on both sides.

[0035] Further, see Figure 1 , 5 Inside the tension hole 12, a positioning block 40 is inserted on the side of the tension block 30 away from the limiting groove 31. By inserting the positioning block 40, the tension block 30 is positioned with the clamping plates 10 on both sides, preventing the tension block 30 from falling off the clamping plates 10.

[0036] In this embodiment, see Figure 5 The positioning block 40 has an L-shaped structure.

[0037] Example 2: See Figure 8 , 9 An emergency door pulley axle disassembly device includes an emergency door pulley axle clamping assembly as described in Embodiment 1, and further includes a pull rod 50, a support frame 60, jacks 70, and a crossbar 80. One end of the support frame 60 is used to install and fix it to the outside of the emergency door during use, and the other end of the support frame 60 is used to install two jacks 70. The telescopic ends of the two jacks 70 face away from the support frame 60, and the telescopic ends of the two jacks 70 jointly support the crossbar 80. A pull rod 50 is installed between the two jacks 70 on the crossbar 80, and the pull rod 50 is connected to a pulling block 30. By pushing the crossbar 80 outward by the two jacks 70, the crossbar 80 simultaneously drives the pull rod 50. The pull rod 50 is connected to the pulling block 30 to pull the pulling block 30 outward, thereby removing the axle 1.

[0038] See Figure 6 , 7One end of the pull rod 50 is equipped with a hook 51, which is hooked onto the tension block 30. The other end of the pull rod 50 is equipped with an external thread 52. A second through hole 81 is provided in the middle of the crossbar 80. The end of the pull rod 50 with the external thread 52 passes through the second through hole 81 and is then screwed onto a nut 53. This structure facilitates the connection between the pull rod 50 and the tension block 30, and also facilitates the adjustment of the position of the crossbar 80 on the pull rod 50 by using the nut 53. Because if the stroke of the jack 70 is insufficient after the axle 1 is pulled out to a certain length, the nut 53 can be turned after the jack 70 is retracted, and the crossbar 80 is then pressed against the extension end of the jack 70. In this embodiment, the pull rod 50 uses an M30 screw.

[0039] See Figure 8 The support frame 60 includes a support plate 61, support columns 62, and connecting columns 63. The support plate 61 has a third through hole 611 in its center for avoiding the wheel axle 1. Multiple fourth through holes 612 are located outside the third through hole 611 on the support plate 61. Support columns 62 are fixedly connected to the four corners of one side of the support plate 61. Connecting columns 63 are fixedly connected to adjacent support columns 62 on the side away from the support plate 61. Two opposing connecting columns 63 support and install jacks 70 during use. The fourth through holes 612 are used to connect to the existing threaded holes on the outside of the emergency door using screws, thus fixing the support frame 60 to the emergency door. The larger end of the wheel axle 1 passes through the third through hole 611.

[0040] Furthermore, to prevent the jack 70 from falling, positioning cylinders 64 for placing the jack 70 are welded and installed on the two opposite connecting columns 63. The side wall of the positioning cylinder 64 is provided with an axial elongated hole 65. The jack 70 adopts a single-acting hydraulic cylinder, and the hydraulic hose connected to the single-acting hydraulic cylinder passes through the elongated hole 65.

[0041] Further, see Figure 9 It also includes two manual hydraulic pumps 90, whose oil supply ports are connected to the hydraulic hoses of two jacks 70, respectively. The two manual hydraulic pumps 90 drive the two jacks 70 to operate. During operation, the two manual hydraulic pumps 90 operate synchronously.

[0042] The working principle or process of this utility model: During disassembly, firstly, use an angle grinder with a grinding wheel to cut a groove 3 into the limiting platform 2. Then, install the clamping plate 10, the limiting plate 20, and the tension block 30 of the clamping assembly onto the limiting platform 2 of the wheel axle 1, as follows. Figure 6 As shown.

[0043] Next, the support frame 60 is bolted to the emergency door, and then the two jacks 70 are installed into the positioning cylinder 64 respectively. Then, the hook 51 of the pull rod 50 is hooked onto the tension block 30, and the other end of the pull rod 50 passes through the second through hole 81 on the crossbar 80 and is screwed with the nut 53. The two ends of the crossbar 80 are respectively abutted against the telescopic ends of the jacks 70.

[0044] Next, operate the manual hydraulic pump 90. During operation, try to keep it synchronized so that the jacks 70 extend. The two jacks 70 push the crossbar 80 outward. The crossbar 80 simultaneously drives the pull rod 50. The pull rod 50 is connected to the tension block 30 to pull the tension block 30 outward, thereby removing the wheel axle 1.

[0045] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Any modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
