[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0025] Reference Figure 1-4 The walking beam translation hydraulic cylinder sensor protection device includes a walking beam 1 and a protection plate 3. The bottom of the walking beam 1 is welded with a shell 2. The right side of the protection plate 3 is in sliding contact with the inner wall of the shell 2. The inner wall of the shell 2 is slidably connected with a control frame 4 through a slide groove. The bottom of the control frame 4 is welded with a fixed plate 6. The bottom of the fixed plate 6 is slidably connected to the bottom inner wall of the shell 2 through a slide groove. A tension spring 5 is welded on the right side of the fixed plate 6. The right end of the tension spring 5 is welded to the right inner wall of the shell 2. The left side of the control frame 4 is rotatably connected with a push rod 7 through a rotating shaft. A matching mechanism and a positioning mechanism are respectively provided in the shell 2, and the positioning mechanism matches the protection plate 3 and the matching mechanism respectively.

[0026] In the present invention, the positioning mechanism includes a telescopic rod 8, a positioning frame 9, a compression spring 10 and an insertion frame 11. The telescopic rod 8 is rotatably connected to the inner wall of the outer shell 2 through a rotating shaft. The telescopic rod 8 and the push rod 7 are rotatably connected through a rotating shaft. The left end of the telescopic rod 8 is rotatably connected to the positioning frame 9 through a rotating shaft. The positioning frame 9 is slidably connected to the inner wall of the outer shell 2 through a slide groove. The insertion frame 11 is slidably connected to the inner side of the positioning frame 9 through a slide groove. The positioning frame 9 is welded to the compression spring 10, and the compression spring 10 is welded to the inner side of the positioning frame 9. Through the positioning mechanism, the positioning mechanism is used to position the protective plate 3 in the outer shell 2 so that the protective plate 3 cannot move in the outer shell 2. The protective plate 3 can be installed in the outer shell 2, and the protective plate 3 can protect the hydraulic cylinder sensor.

[0027] In the present invention, the matching mechanism includes a support frame 12, a blocking frame 13, a connecting rod 14, a matching block 15 and a return spring 16. The support frame 12 is welded to the inner wall of the outer shell 2, and the blocking frame 13 is slidably connected to the inner wall of the outer shell 2 through a slide groove. The blocking frame 13 and the connecting rod 14 are rotatably connected through a rotating shaft, and the connecting rod 14 and the matching block 15 are rotatably connected through a rotating shaft. The matching block 15 is welded to the return spring 16, and the return spring 16 is welded to the bottom inner wall of the outer shell 2. Through the matching mechanism, the matching mechanism is used to position the positioning mechanism in the outer shell 2, so that the positioning mechanism can continuously release the protective plate 3, so that the protective plate 3 is automatically inserted into the outer shell 2 after being disassembled to unlock the positioning mechanism, and the positioning mechanism can automatically install the protective plate 3.

[0028] In the present invention, a positioning groove is provided at the bottom of the protective plate 3, and a positioning block is welded to the top of the positioning frame 9. The outer side of the positioning block is in sliding contact with the inner wall of the positioning groove. After the positioning block is inserted into the positioning groove, the positioning block can block the movement of the protective plate 3 in the outer shell 2, thereby realizing the positioning of the protective plate 3.

[0029] In the present invention, a matching through hole is opened on the right side of the support frame 12, and the right end of the blocking frame 13 slides in contact with the inner wall of the matching through hole. The matching through hole is used for pulling out the blocking frame 13 and inserting the positioning frame 9. After the insertion frame 11 is inserted, the positioning frame 9 can be automatically positioned, so that the insertion frame 11 can position the positioning frame 9.

[0030] In the present invention, a rectangular groove is provided on the right side of the shell 2, and the outer side of the control frame 4 is in sliding contact with the inner wall of the rectangular groove. The rectangular groove is used to block the frame 13 so that it can be pulled on the right side of the shell 2, so that the control frame 4 can control the positioning mechanism in the shell 2 to release the protective plate 3 and unlock the protective plate 3. Example

[0031] The difference between this embodiment and embodiment 1 is that the method of positioning the protective plate 3 in the present invention can be replaced by a method of positioning with bolts. The bolts are inserted from the bottom of the outer shell 2 and threadedly connected to the outer shell 2 so that the top of the bolts fits with the protective plate 3, and the protective plate 3 can be installed. However, the bolt positioning method requires the use of tools to unlock the protective plate 3, and the present invention does not have the above-mentioned disadvantages.

[0032] Working principle: When the protective plate 3 needs to be disassembled, it is only necessary to push the control frame 4 on the right side of the shell 2 so that the control frame 4 moves to the left. The control frame 4 will push the push rod 7, and the push rod 7 will push the telescopic rod 8 to rotate counterclockwise, so that the left end of the telescopic rod 8 presses the positioning frame 9, causing the positioning to drop. At the same time, the control frame 4 will also drive the fixing plate 6 to move to the left, and the fixing plate 6 will stretch the tension spring 5. Then the positioning frame 9 will first disengage from the protective plate 3, unlock the protective plate 3, and then drive the insertion frame 11 to drop, so that the left side of the insertion frame 11 is aligned with the blocking frame 13. The right end fits in, and the control frame 4 is released after the protective plate 3 is pulled out. At this time, the initial states of the compression spring 10 and the return spring 16 are both in a compressed state. When the protective plate 3 is pulled out from the housing 2, it will be separated from the matching block 15. At this time, the elastic potential energy of the return spring 16 will be released, and the return spring 16 will push the matching block 15 to move upward and compress the connecting rod 14. The connecting rod 14 then pulls the blocking frame 13 to move to the left. At this time, the insertion frame 11 can be released, and the insertion frame 11 will move to the left through the elastic potential energy released by the return spring 16 to be inserted into the support frame 12 The matching through hole of the insertion frame 11 can block the movement of the positioning frame 9, so that the positioning of the insertion frame 11 and the control frame 4 can be achieved, and the protective plate 3 can be continuously unlocked. Then, after the hydraulic cylinder sensor is maintained, when the protective plate 3 needs to be installed, the protective plate 3 can be directly inserted into the shell 2. The right side of the protective plate 3 first fits with the left side of the matching block 15, and slides on the left side of the matching block 15, which will push the matching block 15 downward. The matching block 15 first compresses the reset spring 16 and then pushes the connecting rod 14. The connecting rod 14 pushes the right end of the blocking frame 13 to be inserted into the support By pushing the insertion frame 11 in the matching through hole inside the support frame 12 into the positioning frame 9 and compressing the compression spring 10, the positioning frame 9 can be unlocked. At this time, the control frame 4 moves to the right through the rebound of the tension spring 5 and pulls the positioning frame 9 to reset, so that the positioning block on the top of the positioning frame 9 is inserted into the positioning groove at the bottom of the protective plate 3. After the positioning block is inserted into the positioning groove, the positioning block can block the movement of the protective plate 3 in the outer shell 2, so that the positioning of the protective plate 3 can be achieved, and the protective plate 3 can be installed in the outer shell 2. The protective plate 3 can protect the hydraulic cylinder sensor.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
