DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Refer to Figure 1-6As shown, a portable fire-fighting equipment transport vehicle of the utility model comprises a cart 1, and foldable expansion brackets 2 are symmetrically arranged on both sides of the cart 1; at least four universal wheels 3 are arranged at the bottom of the cart 1, and the universal wheels 3 are connected to the cart 1 through a height adjustment component 4; a positioning component 5 matched with a fire-fighting water monitor bracket is arranged at the upper end of the cart 1; and a cart handle 6 is hinged at the front end of the cart 1. Fire hoses and other equipment are loaded through the cart and the expansion bracket, and the fire-fighting water monitor is fixedly placed on the upper end of the cart, which can pass through narrow roads and reduce the physical energy consumption of personnel to complete the long-distance transportation of equipment. And when the cart moves forward, the water hose flows out from the upper end of the cart for laying, which can flexibly and quickly lay a remote water supply trunk line for a long distance by a single person, thereby improving the efficiency of fire fighting.
[0021] At the same time, by setting the height adjustment component to raise the height of the universal wheel, the bottom of the cart can be at a sufficient height from the ground, ensuring that it can pass smoothly on uneven ground. When the universal wheel is retracted to the lowest height, it saves space and is easy to store, and it is convenient to place in the fire truck for transportation.
[0022] In this embodiment, the expansion bracket 2 includes an L-shaped bracket 2a hinged on both sides of the cart 1, and hooks 2b are provided on the L-shaped bracket 2a and the upper end of the cart 1, and the corresponding hooks 2b are connected by a chain 2c; a quick lock 2d for fixing the L-shaped bracket 2a is provided on the cart 1. After adopting this structure, when it needs to be placed in a fire truck for transportation, the L-shaped bracket is rotated to fit the cart and fixed with the quick lock. When it is needed, the lock can be opened to quickly expand, which is convenient and quick.
[0023] In this embodiment, the height adjustment assembly 4 includes a sleeve 4a disposed on the cart 1, and a lifting rod 4b connected to the universal wheel 3 is disposed in the sleeve 4a; two S-shaped guide rails 4c are symmetrically disposed along the axis on the side wall of the sleeve 4a, and a hexagon socket screw 4d matching the guide rail 4c is disposed on the lifting rod 4b, and the widths of the two guide rails 4c are respectively adapted to the nut and screw of the hexagon socket screw 4d. The upper and lower ends of the S-shaped guide rail are formed with upward grooves, and in the storage state, the two ends of the hexagon socket screw are located in the groove at the upper end of the guide rail. When a higher height is required, the lifting rod is pulled down to make the two ends of the hexagon socket screw detach from the upper end groove and move along the guide rail to the lower end groove. In the actual trial process, it was found that when the bottom of the cart was 10-15cm from the ground, the cart could pass through most terrains smoothly, and the height of the vertical section of the guide rail was set according to the diameter of the universal wheel, usually set at 7-11cm.
[0024] Further preferably, a relief groove 4e is formed in a conducting manner below the upper end of the guiding track 4c. When the lifting rod 4b is in a contracted state, the hexagon socket screw 4d is located in the relief groove 4e. When the cart is lifted in the stored state, the hexagon socket screw falls into the relief groove, preventing the hexagon socket screw from sliding down along the guiding track and avoiding the influence caused by the sliding of the lifting rod when the cart is placed on the fire truck.
[0025] In this embodiment, preferably, the positioning assembly 5 includes a plurality of hinge seats 5a provided on the side wall of the upper end of the cart 1. A positioning rod 5b is hinged on the hinge seat 5a, and a positioning hole 5c matching the fire hydrant bracket is provided at the free end of the positioning rod 5b. By hinging the positioning rod, the angle of the positioning rod can swing freely, which can adapt to mobile hydrant brackets of various sizes, and can swing to be closely attached to the outer wall of the cart during storage, reducing the occupied space.
[0026] Further preferably, a magnet 5d is provided on the side wall of the cart 1. In the stored state, the positioning rod 5b is attached to the side wall of the cart 1 and cooperates with the magnet 5d. The positioning rod is fixed by the magnet during storage, preventing the positioning rod from shaking and colliding with the cart or the extension bracket during transportation, which may cause damage to the hinge shaft, and at the same time avoiding the generation of noise caused by the collision. The connection method between the magnet and the side wall of the cart is a connection method that is easy to think of by those skilled in the art, such as gluing or installing through a bracket, which is common knowledge in the art and will not be elaborated here.
[0027] During operation, first, the universal wheels are adjusted to a suitable height, the quick-release lock is opened, the L-shaped brackets on both sides are turned outwards and lowered and fixed by a chain. The water hose is placed in the cart, the water distributor, the water gun and other equipment are placed on the L-shaped brackets. After the positioning rod is rotated to a suitable angle, a mobile hydrant is placed on the top of the water hose and the positioning feet on the mobile hydrant bracket are matched with the positioning holes. The cart can be dragged through the cart handle at the front for laying and transportation.
[0028] The above-mentioned embodiments are the preferred embodiments of the present invention, which are only used to conveniently illustrate the present invention and do not impose any form of limitation on the present invention. Any person with ordinary knowledge in the technical field to which the present invention belongs, if without departing from the technical features of the present invention, makes partial changes or modified equivalent embodiments using the technical content disclosed by the present invention, and without departing from the technical feature content of the present invention, still belongs to the scope of the technical features of the present invention.
