Description

Technical Field

[0001] This utility model relates to the field of pipeline inner wall painting technology, and in particular to a limiting and storage mechanism and a steel bridge drilling and painting device. Background Technology

[0002] Steel bridge decks are highly susceptible to fatigue cracking under the combined effects of long-term vehicle loads, environmental corrosion, and residual welding stress, severely impacting structural safety and durability. Currently, a common practice in engineering is to temporarily treat existing fatigue cracks using crack tip drilling. This method works by drilling a hole of a specific diameter at the crack tip to eliminate stress concentration and slow crack propagation. However, practical engineering applications show that the borehole walls are often not effectively protected against corrosion after drilling, allowing the exposed steel to rapidly corrode in humid, salt spray, and other corrosive environments. Corrosion not only weakens the steel cross-section but, more importantly, under the combined effects of alternating loads and corrosive media, easily induces new fatigue cracks in the borehole walls, creating a vicious cycle of stress-corrosion-fatigue that ultimately accelerates failure in the drilled area.

[0003] However, common steel bridge drilling and painting equipment has difficulty controlling the length of the paint spray tube, and is poorly adapted to workpieces of different depths and specifications. Some equipment uses a flexible storage structure to control the paint spray tube, but the flexibility also brings the problem of the paint spray tube popping out uncontrollably.

[0004] To address the above issues, some devices opt for rigid telescopic sleeves instead. However, rigid telescopic sleeves have relatively poor storage capacity, making it difficult to balance small size and length adaptability. If the sleeve is exposed, its durability is easily affected by external forces and environmental factors. If the sleeve is stored inside, it becomes inconvenient to remove and has poor handling.

[0005] Therefore, there is a need for a limiting and storage mechanism and a steel bridge drilling and painting device that can effectively store and control the workpiece, and that allows the sleeve to extend quickly when unlocked by locking the structure, so as to facilitate the quick pulling of the workpiece. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] Given that rigid telescopic sleeves have relatively poor storage capacity and are difficult to balance small size and length adaptability, if the sleeve is exposed, its durability is easily affected by external forces and environmental factors. If the sleeve is stored inside, it will be inconvenient to take out and have poor operation feel.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a locking component, including a positioning frame and a limiting bolt inserted into one side of the positioning frame; The adjustment assembly includes a positioning element installed at one end of the positioning frame, a lifting assembly elastically connected to the bottom of the positioning element, and a telescopic sleeve disposed on the inner wall of the lifting assembly.

[0009] As a preferred embodiment of the limiting storage mechanism described in this utility model, a limiting hole is fixedly provided on one side of the positioning frame, and a groove is cut on the side wall of the lifting assembly corresponding to the limiting hole. A drag bar is fixedly installed at one end of the limit bolt.

[0010] As a preferred embodiment of the limiting and storage mechanism of this utility model, a support plate is provided on one side of the limiting bolt, and the support plate remains fixed. The drag bar extends through to the other side of the support plate, and the limit bolt is elastically connected to the support plate.

[0011] As a preferred embodiment of the limiting and storage mechanism of this utility model, an adjustment plate is rotatably provided on the top of the positioning frame, and a conveying pipe is inserted through the front and rear of the adjustment plate. One end of the delivery pipe passes through the center of the positioning component and enters the lifting assembly.

[0012] As a preferred embodiment of the limiting and storage mechanism of this utility model, the inner wall of the telescopic sleeve is linearly slidably sleeved on the outer wall of the conveying pipe; the outer wall of the telescopic sleeve and the inner wall of the lifting assembly are rotatably connected.

[0013] As a preferred embodiment of the limiting and storage mechanism of this utility model, the lifting assembly slides along the inner wall of the positioning frame, and the bottom of the lifting assembly is fixedly connected to the extension end. The bottom of the telescopic sleeve is located inside the extension end.

[0014] The beneficial effects of the limiting and storage mechanism of this utility model are: simple operation, only the limiting bolt and the lifting assembly need to be separated, and the lifting assembly can be lowered under the action of elasticity, so that the telescopic sleeve is exposed outside the device, which is convenient for operation.

[0015] Given that traditional equipment is difficult to paint the inner wall of workpieces, it requires specialized large equipment, which is not portable and inconvenient for single-person operation, and is often only suitable for large production lines.

[0016] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: an operating component, including a storage shell sleeved outside the limiting storage mechanism, and a delivery valve disposed on the top of the storage shell.

[0017] As a preferred embodiment of the steel bridge drilling and painting device of this utility model, a marking port is fixedly opened on one side of the housing shell, and the marking port and the support plate are fixedly connected. A handle is attached to the other side of the storage case.

[0018] As a preferred embodiment of the steel bridge drilling and painting device of this utility model, wherein: The top of the delivery valve and delivery pipe are connected, and the bottom of the housing has a fixed operating port. The diameter of the operating port is larger than the diameter of the extension end.

[0019] The beneficial effects of the steel bridge drilling and painting device of this utility model are: simple operation, small size, easy to operate by a single person, high work efficiency, effective painting of the inner wall of drill holes of different depths, stronger adaptability, and effective reduction of the risk of hole wall corrosion and cracking.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0028] Example 1 Reference Figures 1-2 This is the first embodiment of the present invention, which provides a limiting and storage mechanism.

[0029] The locking component 1 is used to control the extension and retraction of the telescopic sleeve 23. By default, the telescopic sleeve 23 is in the retracted state.

[0030] The positioning frame 11 serves as the support frame for the entire limiting and storage mechanism, ensuring its stable operation. A limiting bolt 12 is inserted into one side of the positioning frame 11. When the limiting bolt 12 and the positioning frame 11 are engaged, the subsequent telescopic sleeve 23 is locked. Only when the limiting bolt 12 and the positioning frame 11 are separated can the telescopic sleeve 23 perform subsequent actions.

[0031] Adjustment component 2 is used to adjust the movement of telescopic sleeve 23. In this design, a positioning element 21 is fixedly installed at the top end of the positioning frame 11, and the positioning element 21 itself cannot move. At the bottom of the positioning element 21, the lifting assembly 22 is elastically connected. In this design, a spring is used for the elastic connection. The lifting assembly 22 is cylindrical to fit the telescopic sleeve 23 on the inner wall of the lifting assembly 22.

[0032] The lifting assembly 22 itself can slide along the inner wall of the positioning frame 11. The positioning component 21 restricts the movement space of the lifting assembly 22 by setting the spring. In the default state, the spring is compressed, and the movement trajectory of the lifting assembly 22 is restricted by the cooperation of the limit bolt 12 and the positioning frame 11.

[0033] After the manual control limit bolt 12 and the positioning frame 11 are separated, the limit bolt 12 can no longer prevent the movement of the lifting assembly 22. At this time, the lifting assembly 22 will be pushed out under the action of the spring, so that its bottom and the telescopic sleeve 23 are pushed out to the outside of the entire device housing structure, making it easy to pull the telescopic sleeve 23 from the outside for subsequent adaptation of workpieces of different sizes, greatly increasing the operating feel and improving the work efficiency of the operator.

[0034] Example 2 Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] A limiting hole 111 is provided on one side of the positioning frame 11. In order to match the limiting hole 111, a corresponding slot is provided on the side wall of the lifting assembly 22. This ensures that after the limiting bolt 12 enters the limiting hole 111, it can continue to limit the lifting assembly 22 through the slot.

[0036] A drag bar 121 is fixedly installed at the other end of the limit bolt 12. By pulling the drag bar 121, the limit bolt 12 can be directly operated to control its movement and achieve engagement or disengagement with the limit hole 111. A support plate 122 is provided on one side of the limit bolt 12. The support plate 122 itself can be fixed to the outer shell structure of the device to cooperate with the operation of the limit bolt 12.

[0037] The drag bar 121 extends through to the other side of the support plate 122. Operators can operate the drag bar 121 from the outside of the support plate 122 to control the limit bolt 12. The outer wall of the limit bolt 12 is also equipped with an elastic element for elastic connection with the support plate 122; in this design, the elastic element is a spring. During movement, the limit bolt 12 will inevitably interact with the spring. As the limit bolt 12 gradually separates from the lifting assembly 22, the spring is gradually compressed, generating a counter-force.

[0038] After the limit bolt 12 is completely separated from the lifting assembly 22, it can no longer restrict the movement of the lifting assembly 22. Therefore, the lifting assembly 22, while elastically connected to the positioning member 21, will be pushed downward by the elastic force. At this time, the groove on the side wall of the lifting assembly 22 is misaligned with the limit bolt 12. The operator can loosen the limit bolt 12, and the limit bolt 12 will be elastically contacted by the side wall of the lifting assembly 22, but will no longer affect the movement of the lifting assembly 22.

[0039] An adjustment plate 24 is rotatably mounted on the top of the positioning frame 11. A conveying pipe 241 is fixedly inserted through the front and rear of the adjustment plate 24. During the rotation of the adjustment plate 24, it can drive the conveying pipe 241 to rotate synchronously. The other end of the conveying pipe 241 passes through the center of the positioning component 21 and enters the lifting assembly 22 for subsequent cooperation with the telescopic sleeve 23 inside the lifting assembly 22.

[0040] The top end of the telescopic sleeve 23 is linearly slidably fitted onto the outer wall of the conveying pipe 241, and can move in a suitable linear motion along the conveying pipe 241. The top outer wall of the telescopic sleeve 23 is also rotatably connected to the inner wall of the lifting assembly 22, so when the lifting assembly 22 is pushed by elastic force, it can also drive the telescopic sleeve 23 to move in a suitable synchronous motion.

[0041] The bottom of the lifting assembly 22 is fixedly connected to the extension end 221. The extension end 221 can move synchronously with the lifting assembly 22. After the lifting assembly 22 has completed its elastic movement, the extension end 221 will move with the lifting assembly 22 to the outside of the entire device housing structure, making it easy to pull the telescopic sleeve 23 from the outside for subsequent adaptation of workpieces of different sizes. This greatly increases the operating feel and improves the work efficiency of the operator.

[0042] The inner wall of the telescopic sleeve 23 and the outer wall of the conveying pipe 241 are linearly slidably connected, but the outer wall is also rotatably connected to the inner wall of the lifting assembly 22. Therefore, when the conveying pipe 241 rotates with the adjusting disc 24, it can drive the telescopic sleeve 23 to rotate synchronously. As the main structure for actual painting, the telescopic sleeve 23 has a through-hole on the side wall. When the telescopic sleeve 23 rotates during the painting process, it can adjust the painting direction, thereby ensuring the complete painting effect inside the workpiece. The adjusting disc 24 can be rotated manually or controlled by a stepper motor.

[0043] When the spraying work is finished, the staff can manually retract the telescopic sleeve 23 while overcoming the spring to apply a reset force, allowing the lifting assembly 22 to rise gradually. At this time, the limit bolt 12 is also ready to reset under the action of the spring. Once the groove on the side wall of the lifting assembly 22 aligns with the limit hole 111 and the limit bolt 12 again, the limit bolt 12 will cooperate with the lifting assembly 22 again to achieve the locking effect.

[0044] Example 3 Reference Figures 1-5 This is the third embodiment of the present invention, which is based on any of the above embodiments and adds a steel bridge drilling and painting device.

[0045] The operation component 3 is used to provide convenience for the staff to control the device. Outside the limiting and storage mechanism, a storage shell 31 is fixedly set. In this solution, the storage shell 31 is set as a cuboid structure, which can reliably protect and store the entire limiting and storage mechanism assembly.

[0046] At the top of the housing 31, a delivery valve 32 is fixedly connected. The delivery valve 32 is internally connected to a delivery pipe 241. Through the delivery valve 32, the steel bridge drilling and painting device can be freely and flexibly connected to an external painting structure to adapt to different scene environment requirements, thus having a higher degree of freedom.

[0047] On one side of the storage shell 31, an identification port 311 is fixedly opened. The identification port 311 is used to fixally connect with the support plate 122. While serving as a warning and reminder, the identification port 311 also provides efficient support for the support plate 122, ensuring sufficient stability of the support plate 122 and facilitating the movement of the limit bolt 12. On the other side of the storage shell 31, a handle 312 is also fixedly connected.

[0048] An operating port 313 is fixedly opened at the bottom of the storage shell 31. The operating port 313 allows the extension end 221 to follow the lifting assembly 22 and extend under the action of elasticity. The diameter of the operating port 313 is larger than the diameter of the extension end 221 to ensure that the extension end 221 can work normally.
