Description

Technical Field

[0001] The utility model relates to the technical field of robot chassis, in particular to a universal chassis for an explosion-proof inspection robot. Background Art

[0002] The explosion-proof inspection robot is a special robot designed for performing inspection tasks in explosive environments. It integrates advanced sensor technology, automatic control, artificial intelligence and explosion-proof technology, and can safely operate in flammable and explosive places such as chemical plants, refineries, natural gas stations, mines, ammunition depots, etc., replacing manual inspection work with high risks. Since the environment of flammable and explosive places such as mines is relatively complex, most of them have uneven, narrow or obstructed terrain. Therefore, in order to ensure the normal progress of inspection tasks, explosion-proof quadruped robots are often used for inspection.

[0003] As in the prior art, the patent with the patent authorization announcement number CN218229218U discloses a quadruped robot, including a trunk, and leg moving mechanisms are respectively arranged on both sides of the trunk; mounting frames are respectively arranged at the front and rear ends of the trunk, and the mounting frames are connected to the leg moving mechanisms; the mounting frame includes a vertically arranged support plate, and an upper connecting plate and a lower connecting plate are arranged on the support plate and on one side close to the trunk, and the other ends of the upper connecting plate and the lower connecting plate are respectively detachably connected to the trunk; a first mounting cavity is formed between the upper connecting plate and the lower connecting plate; the leg moving mechanism includes a thigh rod and a calf rod; a rotating assembly is arranged at the upper end of the thigh rod, one end of the rotating assembly is connected to the thigh rod, and the other end is connected to the first mounting cavity; the thigh rod and the calf rod are rotatably connected, and a driving assembly is arranged on the calf rod. Through the above technical scheme, this kind of quadruped robot can walk on some special and complex road conditions, and can avoid falling.

[0004] In the above-mentioned patent, various electronic components required for the explosion-proof quadruped robot are installed in an installation chamber (also called a chassis), and screws are often used to fix the electronic components (such as communication modules, positioning modules or battery packs, etc.) to the chassis. Although this fixing method is relatively simple, since the sizes of the electronic components used by each explosion-proof quadruped robot are different, the positions of the screws for fixing the electronic components are also different. This results in the chassis used for each explosion-proof quadruped robot needing to be specially designed in order to fix various types of electronic components on the chassis. This makes the chassis of each explosion-proof quadruped robot not interchangeable, which increases the difficulty of later maintenance of the explosion-proof quadruped robot. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0022] See also Figure 1-6A universal chassis for an explosion-proof inspection robot comprises a chassis 1, a mounting plate 2 is fixedly connected to the inner side of the chassis 1, a plurality of mounting holes 3 are provided on the mounting plate 2, the mounting holes 3 are equidistantly distributed, a connecting rod 4 is slidably connected inside the mounting hole 3, a positioning ring 5 matching the mounting hole 3 is fixedly connected to the lower end of the connecting rod 4, a nut 6 is threadedly connected to the bottom of the connecting rod 4, the nut 6 is located at the bottom of the mounting plate 2, a clamping block 7 is slidably connected to the top of the connecting rod 4, a clamping groove 701 is provided on one side of the clamping block 7, a slide groove 8 matching the connecting rod 4 is provided inside the clamping block 7, a pull-down elastic member 10 is provided at the upper end of the slide groove 8, the upper end of the pull-down elastic member 10 is fixedly connected to the top of the slide groove 8, and the lower end of the pull-down elastic member 10 is fixedly connected to the connecting rod 4.

[0023] The explosion-proof inspection robot of the utility model uses a universal chassis. When fixing the electronic component 18 on the chassis 1, it is only necessary to select the mounting hole 3 at a suitable position according to the size of the electronic component 18 (the mounting hole 3 is located at the diagonal position of the electronic component 18), and then insert the connecting rod 4 into the selected mounting hole 3, and then tighten the nut 6 to fix the connecting rod 4 on the mounting plate 2. After the two connecting rods 4 are fixed, the block 7 at the upper end of the connecting rod 4 is pulled up, and the electronic component 18 is placed between the two blocks 7, and then the block 7 is released. The elastic member 10 is pulled down to pull the block 7 downward, so that the diagonal of the electronic component 18 is stuck in the slot 701, so that the electronic component 18 can be fixed by the block 7. Due to the large number of mounting holes 3, electronic components 18 of different models and sizes can be fixed without the need for special design of the chassis 1, thereby improving the versatility of the chassis 1, and the fixing method of the electronic component 18 is simple and easy to operate.

[0024] It is worth noting that the card block 7 and the card slot 701 on the card block 7 have different models and sizes, which can fix electronic components 18 of different models and sizes. For example, the cross-section of the card slot 701 can be square (used to fix electronic components 18 with regular shapes, such as battery packs, etc.) or arc-shaped (used to fix circular electronic components 18, such as sensors, etc.).

[0025] like Figure 2 and Figure 3 As shown, a fixing rod 9 is fixedly connected to the top of the connecting rod 4 , and the upper end of the fixing rod 9 passes through the center of the pull-down elastic member 10 and extends to the outside of the clamping block 7 , and a fixing ring 12 is threadedly connected to the fixing rod 9 .

[0026] Specifically, after the block 7 is pulled down by the pull-down elastic member 10 , the fixing ring 12 can be tightened to restrict the block 7 to prevent the block 7 from shaking and causing a collision between the electronic component 18 and the block 7 .

[0027] like Figure 2 and Figure 3 As shown, a thread groove is provided on one side of the outer wall of the fixing rod 9, and half of the circumference of the end face of the fixing rod 9 is greater than the length of the thread groove. A thread block is fixedly connected to one side of the interior of the fixing ring 12, and half of the circumference of the inner ring of the end face of the fixing ring 12 is greater than the length of the thread block.

[0028] Specifically, the threaded block inside the fixing ring 12 corresponds to the threaded groove on the outer wall of the fixing rod 9. During the movement of the blocking block 7, the threaded block and the threaded groove are staggered to allow the blocking block 7 to slide freely. When the blocking block 7 needs to be restricted, the fixing ring 12 is rotated, and the fixing ring 12 can be threadedly connected to the threaded groove on the fixing rod 9 through the threaded block, thereby fixing and restricting the blocking block 7. This structure enables the fixing ring 12 to fix the blocking block 7 by only rotating a certain angle, and the operation is simple and convenient.

[0029] like Figure 3 As shown, the bottom of the fixing ring 12 is fixedly connected with a limiting ring 11, and the limiting ring 11 is rotatably connected with the clamping block 7. The fixing ring 12 is limited and fixed by the limiting ring 11 to prevent the fixing ring 12 from being lost or damaged due to separation from the clamping block 7.

[0030] like Figure 2 and Figure 3 As shown, both sides of the fixing ring 12 are fixedly connected with shifting blocks 13, and the shifting blocks 13 are symmetrically arranged. Rotating the fixing ring 12 by the shifting blocks 13 is more labor-saving and convenient.

[0031] like Figure 2 and Figure 5 As shown, the bottom of the chassis 1 is slidably connected to a bottom plate 17, and the bottom plate 17 is located at the bottom of the nut 6. A cavity 14 is opened at one end of the chassis 1, and a positioning block 16 is slidably connected to the lower end of the cavity 14. A plurality of outward-pushing elastic members 15 are provided on the top of the positioning block 16, and the upper end of the outward-pushing elastic member 15 is fixedly connected to the top of the cavity 14, and the lower end of the outward-pushing elastic member 15 is fixedly connected to the top of the positioning block 16. A positioning groove matching the positioning block 16 is opened at one end of the bottom plate 17.

[0032] Specifically, when the nut 6 is tightened to fix the connecting rod 4, the bottom plate 17 can be pulled out from the bottom of the chassis 1, and after the nut 6 is tightened, the bottom plate 17 can be inserted into the bottom of the chassis 1 to prevent a large amount of dust from entering the interior of the chassis 1 from the mounting hole 3. At the same time, after the bottom plate 17 is inserted into the bottom of the chassis 1, the positioning block 16 can be used to restrict the bottom plate 17 to prevent the bottom plate 17 from detaching from the chassis 1 by itself.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
