DETAILED DESCRIPTION

[0018] The utility model will be further explained in detail in combination with drawing and specific embodiment.

[0019] A kind of maintenance device of fire-fighting equipment, such as Figures 1-2 As shown, including base 1, the top of base 1 is provided with lifting mechanism with drive jacking saddle 5 to lift to carry out fire-fighting equipment maintenance, the bottom of base 1 is provided with support leg 4 at both ends of two sides of front and back respectively, to ensure the stability when jacking saddle 5 is lifted.

[0020] The left and right sides below base 1 are also provided with walking car 2 to drive base 1 to move horizontally, and the bottom of walking car 2 is provided with four universal wheels 3.

[0021] The top surface of walking car 2 is downwardly inclined, and the top of walking car 2 is provided with limiting groove 16 consistent with the inclination angle of the top surface, and the bottom of base 1 is provided with adjusting rod 15 slidingly fitted with limiting groove 16, which drives base 1 and support leg 4 to move up and down, so that base 1 is in a fixed state or a moving state.

[0022] Specifically, when walking car 2 approaches base 1, adjusting rod 15 is lifted to drive support leg 4 to rise, and when walking car 2 moves away from base 1, adjusting rod 15 falls to drive support leg 4 to move down, and when support leg 4 contacts the ground, it stably supports base 1, which can prevent base 1 from sliding.

[0023] Walking car 2 is located between the front and rear support legs 4 and is slidingly connected with the support legs 4, and walking car 2 is connected with the two support legs 4 through a self-locking mechanism.

[0024] The self-locking mechanism includes a self-locking rod 18 penetrating through the support leg 4, the inner end of the self-locking rod 18 is provided with a self-locking block 20, the outer end of the self-locking rod 18 is provided with an operating handle 19 to cancel the self-locking state, and the side walls of the walking car 2 are respectively provided with self-locking grooves connected with the self-locking blocks 20.

[0025] The support leg 4 is also provided with a cylindrical groove 17, the opening side of the cylindrical groove 17 is opposite to the side wall of the walking car 2, and the cylindrical groove 17 is slidingly fitted with the self-locking block 20.

[0026] The outer side of the self-locking rod 18 is sleeved with a spring 21, one end of the spring 21 is connected with the closed end of the cylindrical groove 17, and the other end is connected with the self-locking block 20.

[0027] During the movement of the traveling vehicle 2, the side wall of the traveling vehicle 2 abuts against the outrigger 4, causing the self-locking block 20 to compress the spring 21 and be located inside the cylindrical groove 17. When the self-locking block 20 is aligned with the self-locking groove on the side wall of the traveling vehicle 2 away from the outrigger 4, the spring 21 releases pressure, causing the self-locking block 20 to move into the self-locking groove to form a self-lock. At this time, the traveling vehicle 2 can drive the base 1 to move. When the self-locking block 20 is aligned with the self-locking groove on the side wall of the traveling vehicle 2 near the outrigger 4, the spring 21 releases pressure, causing the self-locking block 20 to move into the self-locking groove to form a self-lock. At this time, the outrigger 4 lands smoothly on the ground, and the base 1 is in a fixed state.

[0028] When it is necessary to cancel the self-locking between the traveling vehicle 2 and the outrigger 4, the self-locking block 20 is inserted into the cylindrical groove 17 by pulling the operating handle outward, thus canceling the connection between the self-locking block 20 and the self-locking groove.

A movable hinge seat 8 is slidably provided on the right side of the base 1 and hinged to the bottom right side of the telescopic frame 6. The movable hinge seat 8 is threadedly connected to the lead screw 9. One end of the lead screw 9 is connected to the motor 11, and the other end of the lead screw 9 is installed on the lead screw mounting seat 10 on the base 1. The lead screw mounting seat 10 is located to the right of the movable hinge seat 8.

[0031] Side plates 12 are provided on the front and rear sides of the bottom of the lifting seat 5. The right side of the side plate 12 is hinged to the right top of the telescopic frame 6. The left top of the telescopic frame 6 is slidably connected to the side plate 12 through the moving shaft 13. A sliding groove 14 is provided on the left side of the side plate 12 to be slidably fitted with the moving shaft 13.

[0032] The above-described lifting mechanism is only one embodiment; the lifting mechanism may also adopt structures such as chains, sprockets, or lead screws.

[0033] To ensure the stability of motor 11, a battery can be installed on base 1 to power the motor.

[0034] In use, first, move the traveling carriage 2 to connect the self-locking block 20 to the self-locking groove away from the outrigger 4, so that the outrigger 4 is away from the ground. Move the equipment to the position that needs maintenance using the traveling carriage 2. Then, pull out the operating handle 19 to cancel the self-locking state. Move the traveling carriage 2 towards the outrigger so that the outrigger 4 is in contact with the ground and the self-locking block 20 is connected to the self-locking groove near the outrigger 4 to ensure that the equipment is in a stable state.

[0035] Then, standing on the jacking seat 5, starting the motor, making the telescopic frame drive the jacking seat 5 to jacking to the appropriate position, and then the fire-fighting equipment can be maintained.

[0036] The utility model provides a kind of maintenance device of fire-fighting equipment, the distance of adjusting support leg and ground is adjusted by the cooperation of walking car and adjusting rod, so that support leg is far away from ground when needing to move maintenance device, so that maintenance device moves conveniently, support leg is adhered to ground when being repaired, so as to ensure the stability of maintenance device, and by setting self-locking mechanism between walking car and support leg, it is avoided that base is deviated by walking car sliding, the stability of equipment maintenance is improved.
