[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, Figures 1-4 As shown, a petrochemical device maintenance tool includes a connecting handle 1, one end of the connecting handle 1 is provided with a hammer head 3, the end of the connecting handle 1 away from the hammer head 3 is integrally formed with a connecting seat 4, the end of the connecting seat 4 away from the connecting handle 1 is symmetrically fixedly connected to two support plates 8, a fixing cylinder 9 is fixedly connected between the two support plates 8, the outer wall of the fixing cylinder 9 is slidably sleeved with a switching turntable 6, the top end of the switching turntable 6 is circumferentially equidistantly provided with a plurality of inner angle grooves 7, the bottom end of the switching turntable 6 is circumferentially equidistantly provided with a plurality of jaws 5, the plurality of jaws 5 are respectively located at the bottom ends of the plurality of inner angle grooves 7, the inner diameters of the plurality of inner angle grooves 7 and the plurality of jaws 5 gradually increase in a counterclockwise direction, and a locking mechanism for rotating and locking the switching turntable 6 is provided on the connecting handle 1;

[0035] The locking mechanism includes:

[0036] A positioning assembly is provided on the fixed cylinder 9, and is used to perform rotational positioning on the switching turntable 6;

[0037] The positioning assembly is a positioning block 208 disposed inside the fixed cylinder 9. The positioning block 208 passes through the fixed cylinder 9 to the interior of the switching dial 6. The positioning block 208 is slidably connected to the fixed cylinder 9. The outer wall of the positioning block 208 at the position where it meets the switching dial 6 is hemispherical. The inner wall of the switching dial 6 is equidistantly provided with a plurality of positioning slots that coincide with the outer wall of the positioning block 208. The plurality of positioning slots correspond to the plurality of inner corner slots 7.

[0038] The positioning block 208 is provided with a first limiting component, which is used to limit the movement of the positioning block 208;

[0039] In this embodiment, when in use, the corresponding parts on the petrochemical device can be screwed according to the jaws 5 and the inner angle grooves 7, so as to perform corresponding maintenance work on the petrochemical device;

[0040] When it is necessary to switch the inner angle groove 7 and the jaw 5 according to the model of the component, the hammer head 3 is rotated to release the limit lock of the positioning block 208 through the locking mechanism;

[0041] Then, the switching dial 6 is manually pulled to rotate along the outer wall of the fixed cylinder 9. At the same time, the positioning block 208 slides along the inner wall of the fixed cylinder 9 through the positioning slot under the pressure of the inner wall of the switching dial 6. At this time, the locking mechanism can realize the purpose of convenient rotation and positioning of the switching dial 6.

The two second connecting plates 209 respectively pass through the fixed cylinder 9 to the outside of one end of the support plate 8. The second connecting plates 209 are slidably connected to the support plate 8 and the fixed cylinder 9.

[0045] A reset assembly is provided inside the fixed cylinder 9, and the reset assembly is used to push the limit plate 207 to slide and reset;

[0046] The reset component is a spring 206 provided at one end of the limit plate 207 away from the positioning block 208. One end of the spring 206 contacts the outer wall of the limit plate 207, and the other end of the spring 206 contacts the inner wall of the fixed cylinder 9. The limit plate 207 cooperates with the second connecting plate 209 to limit the movement of the positioning block 208. At the same time, the spring 206 can push the limit plate 207 to make the positioning block 208 engage and limit the switching dial 6.

[0047] A transmission assembly is provided on the connecting handle 1;

[0048] In one embodiment, Figures 1-4 As shown, the transmission assembly includes:

[0049] A connecting slip ring 205 is slidably sleeved on the outer wall of the connecting handle 1. One end of the connecting slip ring 205 is symmetrically fixedly connected to two first connecting plates 204. The two first connecting plates 204 are respectively located at the upper and lower ends of the connecting handle 1. The two first connecting plates 204 are respectively fixedly connected to two second connecting plates 209;

[0050] A synchronization component is provided on the connecting handle 1;

[0051] The synchronization component is a limited sliding shaft 202 provided inside the connecting handle 1, and the limited sliding shaft 202 is slidably connected to the connecting handle 1;

[0053] The second limiting assembly includes: two limiting blocks 203 symmetrically fixedly connected to the outer wall of the limiting sliding shaft 202, both of which pass through the connecting handle 1 and are fixedly connected to the connecting slip ring 205. Both limiting blocks 203 are slidably connected to the connecting handle 1. Through the mutual cooperation of the transmission assembly, the synchronization assembly and the second limiting assembly, the second connecting plate 209 can drive the limiting sliding shaft 202 to move synchronously during the movement process;

[0054] The connecting handle 1 is provided with a locking assembly, which is used to lock and limit the limiting sliding shaft 202;

[0055] In one embodiment, Figure 2-Figure 3 As shown, the locking assembly is a threaded rod 201 arranged at one end of the limiting sliding shaft 202. The threaded rod 201 passes through the connecting handle 1 and is fixedly connected to the hammer head 3. The threaded rod 201 is threadedly connected to the connecting handle 1. The threaded rod 201 squeezes and locks the limiting sliding shaft 202, and the positioning block 208 can be synchronously locked, thereby preventing the switching turntable 6 from rotating during use.

[0056] The above embodiment discloses a petrochemical device maintenance tool, wherein when in use, the corresponding parts on the petrochemical device can be screwed according to the jaws 5 and the inner angle grooves 7, thereby performing corresponding maintenance work on the petrochemical device;

[0057] When it is necessary to switch the inner angle groove 7 and the jaws 5 according to the model of the component, the threaded rod 201 is rotated by the hammer head 3. At this time, the threaded rod 201 gradually moves along the inner wall of the connecting handle 1 through the threaded connection between the threaded rod 201 and the connecting handle 1, and the threaded rod 201 is separated from the outer wall of one end of the limiting sliding shaft 202 by moving, thereby releasing the limit lock of the limiting sliding shaft 202;

[0058] When the second locking plate 209 is engaged, the spring 206 pushes the limiting plate 207 to slide along the outer wall of the connecting handle 1, thereby preventing the locking plate 205 from sliding along the inner wall of the connecting handle 1. When the second locking plate 209 is engaged, the spring 206 pushes the limiting plate 207 to slide along the inner wall of the connecting handle 1. When the second locking plate 209 is engaged, the spring 206 pushes the limiting plate 207 to slide along the inner wall of the connecting handle 1.

[0059] When the jaws 5 or the inner angle groove 7 are rotated to the specified position as required, rotating the hammer head 3 can cause the threaded rod 201 to squeeze the end of the limiting sliding shaft 202, thereby locking the switching dial 6 in rotation, thereby further improving the applicability of the maintenance tool, thereby effectively reducing the difficulty of storing and managing the maintenance tool during maintenance.
