Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting robots, and more specifically, to a supporting device for a fire-fighting robot. Background Art

[0002] With the rapid development of robot technology, firefighting robots are increasingly used to replace firefighters to enter the front line of fire scenes to fight fires, which has significantly improved the actual combat capabilities of fire brigades to extinguish extremely large and vicious fires, and has also played an important role in reducing national property losses and casualties of firefighting and rescue personnel.

[0003] When the fire-fighting robot enters the designated position, a supporting device is usually used to support it. In order to facilitate the movement of the fire-fighting robot, universal wheels are installed at the bottom of the supporting device to facilitate the movement of the fire-fighting robot. However, during the work of the fire-fighting robot, the fire-fighting robot is supported by universal wheels, which results in a small contact area between the fire-fighting robot and the ground. The fire-fighting robot is very easy to move while working, and it is very difficult for firefighters to control the fire-fighting robot. Therefore, a supporting device for the fire-fighting robot is needed. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 4 In the utility model, a support device for a fire-fighting robot comprises a base 1, a mounting groove 2 is provided on both sides of the base 1, a support rod 3 is rotatably connected to the inner walls of the two mounting grooves 2, a support plate 4 fixedly connected to the two support rods 3 is sleeved on the two support rods 3, two universal wheels 5 are installed at the bottom of the two support plates 4, a gear 6 fixedly connected to the two support rods 3 is sleeved on the two support rods 3, a tooth plate 7 meshing with the gear 6 is slidably connected to the inner walls of the mounting grooves 2, and a driving mechanism 8 is provided in the base 1; the driving mechanism 8 comprises two Cavity 801, two cavities 801 are opened on the base 1, the opposite sides of the two tooth plates 7 penetrate the base 1 and extend into the two cavities 801 respectively, a dual-axis motor 802 is installed inside the base 1, the two output shafts of the dual-axis motor 802 are fixedly connected with screw rods 803, the other ends of the two screw rods 803 penetrate the base 1 and are rotatably connected to the inner walls of the two cavities 801 respectively, the two screw rods 803 are sleeved with sliders 804 threadedly connected thereto, and one side of the two sliders 804 is fixedly connected to the two tooth plates 7 respectively.

[0027] In the utility model, when in use, the fire-fighting robot is installed on the base 1, and the universal wheel 5 at the bottom of the base 1 is used to support it. The setting of the universal wheel 5 allows the user to move the fire-fighting robot to a designated position very easily. When the fire-fighting robot is working, the user turns on the dual-axis motor 802 to drive the two screw rods 803 to rotate. Since the screw rods 803 are threadedly connected to the slider 804, the two sliders 804 will slide along the inner wall of the corresponding cavity 801. During the process, the slider 804 will drive the tooth plate 7 to slide along the inner wall of the installation groove 2. Since the tooth plate 7 is meshed with the gear 6, the gear 6 will be driven to rotate, and the support rod 3 will then drive the support plate 4 to rotate. After the support plate 4 rotates ninety degrees, the support plate 4 will rotate into the installation groove 2. At this time, the bottom of the base 1 will contact the ground, thereby greatly increasing the contact area between the support device and the ground, increasing the friction between the support device and the ground, and improving the stability of the support device supporting the fire-fighting robot.

[0028] See also Figures 1 to 4 , wherein: a hinge ball 9 is fixedly connected to the top of the base 1, a mounting plate 10 movably connected thereto is sleeved on the hinge ball 9, four electric push rods 11 fixedly connected thereto are inserted through the top of the base 1, and the tops of the four electric push rods 11 are fixedly connected to support blocks 12.

[0029] In the utility model, when in use, the electric push rod 11 drives the support block 12 to be in close contact with the mounting plate 10, thereby achieving the effect of supporting and locking the mounting plate 10. The fire-fighting robot will be installed on the top of the mounting plate 10. In actual use, the user can drive the support block 12 to lose its close contact with the mounting plate 10 by reversely opening the electric push rod 11, and then the user can rotate the mounting plate 10, thereby achieving the purpose of adjusting the angle of the fire-fighting robot. The user can drive the mounting plate 10 to rotate on the articulated ball 9 by starting the electric push rod 11 forward and reversely, thereby changing the horizontal degree of the mounting plate 10, achieving the purpose of horizontal adjustment of the fire-fighting robot, and thus being more conducive to the stable operation of the fire-fighting robot and improving the practicability of the device.

[0030] See also Figure 4 , wherein: the top of the support block 12 is fixedly connected with an anti-skid pad 13 , and the top of the anti-skid pad 13 is in contact with the mounting plate 10 .

[0031] In the present invention, the provision of the anti-slip pad 13 can increase the friction force, improve the stability of the support block 12 locking the mounting plate 10, and thus improve the practicality of the device.

[0032] See also Figure 4, wherein: a square cavity 14 is opened inside the base 1, and two electric push rods 15 fixedly connected thereto are embedded in the inner wall of the square cavity 14, a square plate 16 is fixedly connected between the two electric push rods 15, and evenly distributed plug rods 17 are fixedly connected to the bottom of the square plate 16.

[0033] In the utility model, when working on the top of the soil, the user can drive the square plate 16 to descend by turning on the electric push rod 2 15. After the square plate 16 descends, it will drive the insertion rod 17 to slide out of the base 1, and the insertion rod 17 will be inserted into the soil, thereby further increasing the stability of the fire-fighting robot support.

[0034] See also Figure 4 , wherein: the bottom of the base 1 is fixedly connected with uniformly distributed anti-sliding blocks 18, and the anti-sliding blocks 18 are sleeved on the insertion rod 17 and slidably connected thereto.

[0035] In the utility model, the anti-sliding block 18 can support the base 1 on the cement pavement, increase the friction between the base 1 and the ground, further enhance the stability of the support for the fire-fighting robot, and when the insertion rod 17 is retracted into the base 1, the dirt on the surface of the insertion rod 17 can be cleaned, thereby improving the practicability of the device.

[0036] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
