Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof robots, in particular to a radar mounting bracket for explosion-proof robots. Background Art

[0002] The explosion-proof inspection robot is a special robot designed for performing inspection tasks in an environment with explosion hazards. When the explosion-proof robot moves forward, it needs to use a radar, which is equivalent to the eyes of the explosion-proof robot. When selecting the radar, it is necessary to actually match the radar with the robot to test the applicability of the radar. The radar is usually directly installed on the robot chassis through a radar bracket. Since robots of the same appearance need to be installed with different types of radars for testing, and different types of radars have different appearance sizes, the assembly of different types of radars is very cumbersome.

[0003] The existing patent document with announcement number CN214394264U discloses a radar mounting structure and a robot having the same, including: a bracket installed on the robot chassis; a radar connected to the bracket through an adjusting pad; an adjusting pad arranged between the bracket and the radar, the adjusting pad including a plurality of adjusting pads, and each adjusting pad having a different thickness along the assembly direction of the radar toward the bracket to adjust the distance from the radar to the robot chassis.

[0004] However, the above device has the following problems when used:

[0005] When the explosion-proof robot is in use, due to its different working scenarios, it needs to be equipped with different radars to adapt to different usage requirements, and thus requires different radar mounting brackets. However, when using the equipment, it is necessary to prepare in advance adjustment pads, adapter plates and other related objects that match the size of the installed sensor. The installation process also requires manual alignment of holes and tightening of screws, which is extremely inconvenient. When replacing another radar, it is also necessary to remove the adjustment pads and adapter plates, and then install the corresponding models of adjustment pads and adapter plates, which is costly and inefficient.

[0006] To this end, we propose a radar mounting bracket for an explosion-proof robot to solve the above problems. Utility Model Content

[0027] 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.

[0028] See also Figures 1 to 7 A radar mounting bracket for an explosion-proof robot comprises a robot body 1. The robot body 1 is provided with a mounting cavity 2. The mounting cavity 2 is used to install different radar components to adapt to different usage requirements.

[0029] A driving gear 3 is rotatably installed inside the installation cavity 2, and two passive tooth plates 4 are slidably installed inside the installation cavity 2. A placement plate 5 is fixedly installed on the two passive tooth plates 4, and the driving gear 3 is in meshing relationship with the two passive tooth plates 4;

[0030] When the driving gear 3 is rotated, the two passive gear plates 4 will move closer to or farther from each other, and thus the distance between the two placement plates 5 on the X-axis will change, so that the length of the placement radar component can be adjusted specifically.

[0031] A rotating rod 9 is fixedly installed at the center of the driving gear 3, and a hand wheel 10 is fixedly installed on the other end of the rotating rod 9;

[0032] The hand wheel 10 is manually rotated, and the rotation of the hand wheel 10 causes the rotating rod 9 to rotate, thereby driving the driving gear 3 to rotate synchronously.

[0033] Internally threaded sleeves 11 are slidably mounted on the two placement plates 5, and the distance between the two internally threaded sleeves 11 on the Y axis can be specifically adjusted according to the size of the radar component.

[0034] The internal threaded sleeve 11 is connected to a threaded rod 12 by threads, and a pressure block 13 is arranged at one end of the threaded rod 12 away from the internal threaded sleeve 11. The pressure block 13 changes in height as the height of the threaded rod 12 changes, but does not rotate therewith.

[0035] A rotating member 14 is fixedly mounted on one end of the threaded rod 12 which is away from the internal threaded sleeve 11 .

[0036] By rotating the rotating member 14, the rotation of the rotating member 14 causes the threaded rod 12 to rotate synchronously, and there is a threaded fit between the threaded rod 12 and the internal threaded sleeve 11, so the threaded rod 12 can smoothly extend or retract into the internal threaded sleeve 11, thereby changing the height of the edge clamp 13, so that the limit on the Z axis can also be specifically adjusted according to the height of the radar component.

[0037] A limiting tooth block 19 is fixedly installed inside the placement plate 5, and a sliding plate 21 is also slidably installed inside the placement plate 5. A return spring 22 is fixedly installed on the sliding plate 21, and a fixed rack 20 is fixedly installed on the other end of the return spring 22. When it is in a state without external force, under the action of the thrust of the return spring 22, the teeth on the fixed rack 20 are located inside the tooth grooves on the limiting tooth block 19, and the limiting tooth block 19 cannot move.

[0038] The limiting tooth block 19 is matched with the fixed rack 20 , a connecting rod 18 is fixedly mounted on the fixed rack 20 , and the other end of the connecting rod 18 passes through the internal threaded sleeve 11 and a pressing block 17 is fixedly mounted thereon.

[0039] When the pressing block 17 is pressed, the connecting rod 18 can be moved, and then the connecting rod 18 drives the limiting tooth block 19 to move, so that the limiting tooth block 19 is separated from the fixed rack 20. At this time, the internal threaded sleeve 11 can be moved smoothly, so as to perform targeted distance adjustment on the Y-axis according to the belt of different radar components.

[0040] The placement plate 5 is provided with a slide groove 7 for the connecting rod 18 to slide. When the connecting rod 18 moves, the connecting rod 18 moves on the slide groove 7, so that the connecting rod 18 can only move in a fixed direction.

[0041] The two edge pressing blocks 13 are both fixedly mounted with limiting rods 15 , and the internal threaded sleeve 11 is provided with limiting grooves 16 at corresponding positions for the limiting rods 15 to slide.

[0042] Through the cooperation between the limiting rod 15 and the limiting groove 16, the edge pressing block 13 does not rotate but only moves up and down, thereby ensuring the fixing effect of the corners of the radar component.

[0043] An indicating arrow 8 is fixedly mounted on one of the internal threaded sleeves 11 , and a length mark 6 is provided at a corresponding position of the robot body 1 , and the length mark 6 corresponds to the indicating arrow 8 .

[0044] When the placement plate 5 moves, the indicator arrow 8 moves on the length mark 6, and the corresponding length data changes, so that the operator can smoothly know the distance between the two placement plates 5, so that the radar component can be smoothly and initially placed on the placement plate 5, which is convenient for subsequent installation activities.

[0045] The working process of the utility model is: first, manually rotate the hand wheel 10 to rotate the active gear 3, and the two passive gear plates 4 will get closer to or farther away from each other, so that the distance between the two placement plates 5 on the X-axis changes. At the same time, the indicating arrow 8 moves on the length mark 6, so that the operator can smoothly know the distance between the two placement plates 5, until the placement activity of the radar component can be smoothly carried out.

[0046] The radar assembly is placed on two placement plates 5, and then the active gear 3 is rotated so that the two placement plates 5 clamp the radar assembly. Then, the pressing block 17 is pressed to move the connecting rod 18, and then the connecting rod 18 drives the limiting tooth block 19 to move, so that the limiting tooth block 19 is separated from the fixed rack 20. At this time, the internal threaded sleeve 11 can move smoothly, so as to perform targeted distance adjustment on the Y axis according to the size of different radar assemblies.

[0047] When the internally threaded sleeve 11 abuts against the edge of the radar assembly, the force applied to the pressing block 17 is canceled. Under the thrust of the reset spring 22, the teeth on the fixed rack 20 are located inside the tooth grooves on the limiting tooth block 19, so that the limiting tooth block 19 cannot move, and the distance between the two internally threaded sleeves 11 on the Y axis remains stable.

[0048] The rotating member 14 rotates, and the rotation of the rotating member 14 causes the threaded rod 12 to rotate synchronously. The threaded rod 12 can smoothly extend or retract into the internal threaded sleeve 11, thereby changing the height of the edge clamping block 13, so that the limit on the Z axis can also be specifically adjusted according to the height of the radar component.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
