Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically a visual inspection structure for an explosion-proof robot. Background Technology

[0002] Explosion-proof robots are automated devices specifically designed for flammable and explosive environments. They can perform high-risk tasks in hazardous locations where explosive gases, dust, or fibers are present, replacing manual operations to ensure personnel safety. Their core functions include environmental monitoring, equipment maintenance, hazardous material handling, and emergency rescue, and they are widely used in petrochemical, mining, military, and fire protection industries.

[0003] In the prior art, such as the explosion-proof inspection robot disclosed in patent publication number CN221496075U, there is a cabin and multiple drive mechanisms installed in cooperation with the cabin. The drive mechanism includes wheels, at least one swing arm, shock absorber and driver. The driver is used to drive the wheels to rotate. The swing arm is disposed between the cabin and the wheels and is hinged to the cabin and the wheels respectively. One end of the shock absorber is connected to the cabin, and the other end of the shock absorber moves with the wheels. A connecting component is provided between the shock absorber and the cabin. The connecting component includes a locking block that slides vertically along the outer wall of the cabin and a locking member for fixing the locking block to the cabin. The locking block is hinged to the shock absorber.

[0004] Although the above-mentioned device solves the problem of shock absorber adjustment, it still has the following defects: The robot's visual inspection structure consists of two explosion-proof cameras and a column connected to the gimbal. The rotation of the gimbal drives the explosion-proof cameras to rotate axially and vertically. However, when the cameras need to be repaired, the disassembly of the column and the gimbal is inconvenient. Since the bottom of the column and the top of the gimbal are installed with multiple screws, special tools are required to remove multiple screws, which is time-consuming and laborious. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a visual inspection structure for explosion-proof robots, making the assembly and disassembly of the column and the gimbal simple and convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection structure for an explosion-proof robot, comprising a visual inspection structure body connected to the robot body, a column connected to the visual inspection structure body, a base connected to the robot, and a gimbal connected to the base. The gimbal is a U-shaped structure consisting of an arc segment and two rectangular segments. A plate is fixedly connected to the bottom of the column. A slot corresponding to the plate is provided on one side of the gimbal. An L-shaped baffle is hinged to one side of the rectangular segment of the gimbal. A rod is inserted into the top surface of the L-shaped baffle away from the hinge. One end of the rod passes through the L-shaped baffle and is inserted into the rectangular segment.

[0007] Furthermore, a pull ring is fixedly connected to the top end of the insertion rod.

[0008] Furthermore, a pressing block is fixedly connected to the side of the L-shaped baffle near the insert plate, and the pressing block abuts against the outer end of the insert plate.

[0009] Furthermore, a wire groove is provided at the end of the insert plate away from the L-shaped baffle.

[0010] Furthermore, the rectangular segment has a sliding groove on one side of the insertion rod, and an insertion block is slidably connected in the sliding groove. The insertion block is inserted into the insertion rod, and a spring is fixedly connected to the end of the insertion block away from the insertion rod. The other end of the spring is fixedly connected to the inner wall of the sliding groove.

[0011] Furthermore, a limiting rod is fixedly connected to the end of the insert block away from the insert rod, the limiting rod is slidably connected to the sliding groove, and a spring is sleeved on the outside of the limiting rod.

[0012] Furthermore, the insert block is configured as an L-shaped block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model uses a combination of insert plate, slot, L-shaped baffle and insert rod to connect the column and the gimbal with a plug-in detachable structure. Compared with the traditional connection method that requires multiple bolts to fasten, this design simplifies the disassembly and assembly process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a visual inspection structure for an explosion-proof robot includes a visual inspection structure body 2 connected to the body of an inspection robot 1, a column 3 connected to the visual inspection structure body 2, a base 4 connected to the inspection robot 1, and a gimbal 5 connected to the base 4. The gimbal 5 is a U-shaped structure composed of an arc segment 51 and two rectangular segments 52. A plate 6 is fixedly connected to the bottom of the column 3. A slot 8 corresponding to the plate 6 is opened on one side of the gimbal 5. An L-shaped baffle 7 is hinged to one side of the rectangular segment 52 of the gimbal 5. A rod 10 is inserted into the top surface of the L-shaped baffle 7 away from the hinge. One end of the rod 10 passes through the L-shaped baffle 7 and is inserted into the rectangular segment 52.

[0022] like Figure 1 As shown, the visual inspection structure of the explosion-proof robot in this utility model is similar to that of an existing explosion-proof inspection robot, such as the explosion-proof inspection robot disclosed in patent publication number CN221496075U. The main improvement of this utility model is that it makes the disassembly and assembly between the column and the gimbal simple and convenient. Figures 1 to 4 As shown, when the visual inspection structure of the explosion-proof robot in this utility model is in use, during the movement of the inspection robot 1, the drive structure (existing technology, not shown in the figure) in the base 4 inside the inspection robot 1 drives the gimbal 5 to rotate. When the gimbal 5 rotates, it drives the column 3 and the visual inspection structure body 2 on the top of the column 3 to rotate, so as to realize the all-round inspection work.

[0023] When the visual inspection structure body 2 needs to be repaired, the column 3 and the pan-tilt head 5 can be disassembled. During disassembly, the insertion rod 10 is pulled out, so that the insertion rod 10 is disengaged from the L-shaped baffle 7, so that the L-shaped baffle 7 loses its limit. Then, the L-shaped baffle 7 is rotated, which drives the L-shaped baffle 7 to rotate hinged to the outside of one of the rectangular segments 52, so that the L-shaped baffle 7 is disengaged from the insertion plate 6. At this time, the insertion plate 6 is disengaged from the slot 8 in the pan-tilt head 5, so that the column 3 and the pan-tilt head 5 can be disassembled.

[0024] With the cooperation of the insert plate 6, slot 8, L-shaped baffle 7 and insert rod 10, the column 3 and the gimbal 5 adopt a plug-in detachable structure. Compared with the traditional connection method that requires multiple bolts to tighten, this design simplifies the disassembly and assembly process. Whether it is disassembly during daily maintenance or reassembly after inspection, it can be completed quickly through the plug-in action, which greatly improves the operating efficiency.

[0025] like Figure 3and Figure 4 As shown, a pull ring 12 is fixedly connected to the top of the insertion rod 10. The pull ring 12 facilitates the pulling operation of the insertion rod 10.

[0026] like Figure 2 and Figure 3 As shown, an extrusion block 9 is fixedly connected to the side of the L-shaped baffle 7 near the insert plate 6, and the extrusion block 9 abuts against the outer end of the insert plate 6.

[0027] Specifically, when the L-shaped baffle 7 abuts against the insert plate 6, the pressing block 9 abuts against the insert plate 6. This arrangement allows the L-shaped baffle 7 to abut the insert plate 6 more stably.

[0028] The extrusion block 9 here is an elastic element with a certain degree of elasticity, which ensures more stable extrusion.

[0029] like Figure 3 As shown, a wire groove 61 is provided at the end of the insert plate 6 away from the L-shaped baffle 7.

[0030] Specifically, in order to ensure that when the column 3 and the insert plate 6 are inserted into the slot 8, the cable used to drive the vision detection structure body 2 can be connected to the drive structure in the base 4 first (the connection method here is mostly plug-to-plug, which is a common cable connection method).

[0031] By using the cable tray 61, when the plug-in board 6 is plugged into the slot 8, the already connected cables can be made to move freely in the cable tray 61 without obstructing the plug-in board 6 from the slot 8.

[0032] like Figure 3 and Figure 4 As shown, a rectangular segment 52 has a sliding groove 53 on one side of the insertion rod 10. An insertion block 11 is slidably connected in the sliding groove 53. The insertion block 11 is inserted into the insertion rod 10. A spring 14 is fixedly connected to one end of the insertion block 11 away from the insertion rod 10. The other end of the spring 14 is fixedly connected to the inner wall of the sliding groove 53.

[0033] Specifically, before the insertion of the rod 10, the insertion block 11 is pulled, causing the insertion block 11 to slide within the sliding groove 53. At the same time, the sliding of the insertion block 11 compresses the spring 14. After the insertion of the rod 10 is fixed, the insertion block 11 is released, and the elastic potential energy of the spring 14 pushes the insertion block 11 to return to its original position, so that the insertion block 11 and the insertion rod 10 are fixed together. This makes the insertion of the rod 10 more stable and secure.

[0034] Spring 14 can be made of silicon-manganese spring steel (such as 60Si2MnA), which has a high elastic limit, good tempering stability and mechanical properties, and is suitable for scenarios that bear large loads and require long-term stable operation, such as the cushioning and reset of robot moving parts; or chromium-vanadium steel (such as 50CrVA), which has excellent fatigue resistance and impact resistance, and is suitable for explosion-proof environments with extremely high reliability requirements, reducing the risk of spring failure due to vibration. The elastic modulus of spring 14 is 8-12 N / mm, which meets the requirements of operating conditions from -40℃ to 150℃, improving fatigue service life.

[0035] like Figure 4 As shown, the end of the insert block 11 away from the insert rod 10 is fixedly connected to a limiting rod 13, the limiting rod 13 is slidably connected to the sliding groove 53, and the spring 14 is sleeved on the outside of the limiting rod 13.

[0036] Specifically, when the insert 11 slides in the sliding groove 53, the limiting rod 13 moves accordingly. By using the limiting rod 13, the insert 11 can move horizontally and stably in the sliding groove 53.

[0037] like Figure 4 As shown, the insert 11 is configured as an L-shaped block. The L-shaped design of the insert 11 facilitates its movement.

[0038] In actual assembly, the insert 11, spring 14, and limit rod 13 are all installed within the sliding groove 53. For ease of maintenance, the rectangular section 52 can be designed as a detachable splicing structure, fixed as a whole by screws. When the spring 14 experiences elastic decay or failure due to long-term use, simply remove the splicing screws of the rectangular section 52 to open the sliding groove 53 and directly replace the aged spring 14, insert 11, or limit rod 13 without disassembling the entire gimbal 5 structure.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
