The invention is further described in connection with the following examples.

See fig. 3, shelter extension formula hosepipe lays fire engine in this embodiment, including automatic band subassembly 4 that receive and releases, carriage 1, locomotive 2, a controller, drive controller's start button, locomotive 2 drives carriage 1 and removes, be provided with the accommodation space who is used for accomodating hosepipe 3 in carriage 1, automatic band subassembly 4 is connected and sets up in the top of accommodation space with carriage 1 to receive and release, the automatic band subassembly 3 of collecting and releasing of controller drive is collected to automatic band subassembly 4, automatic band subassembly 4 of receiving and releasing is used for collecting the hosepipe 3 of scattering on ground, automatic band subassembly 4 of receiving and releasing can remove in the top of accommodation space according to the instruction that the controller sent, thereby put into accommodation space with hosepipe 3 that automatic band subassembly 4 of receiving and releasing was collected, the realization is to accomodating of hosepipe 3. The starting key is arranged in a main control panel of the fire engine.

Automatic receive and release area subassembly 4 includes step motor, support frame, two roller groups of upper and lower opposition, sets up the frame that lifts up in the roller group bottom surface, and every roller group is formed by a plurality of gyro wheels setting side by side, and two roller groups level parallel respectively for guarantee that hosepipe 3 of transportation between two roller groups can level and go through. All the parcel has the transmission band outside each roller train, and each roller train rotates by a step motor drive, and each step motor's drive shaft sets up with an arbitrary gyro wheel is coaxial in the roller train respectively, and step motor drives one of them gyro wheel clockwise or anticlockwise rotation to drive whole roller train and rotate. The support frame is the structure of L style of calligraphy, wherein, the one end of perpendicular to horizontal plane and carriage 1 length direction's lateral wall fixed connection, and the other end that the level is parallel erects in the top of accomodating space, is provided with telescopic machanism, for example telescopic cylinder at the horizontal parallel portion of support frame, and telescopic machanism drives and lifts up the frame and can move around the accomodating space top.

The support frame parts which are parallel horizontally are of rectangular structures, the rectangular structures are arranged on the edges of the periphery of the containing space, the four sides of each rectangular structure are provided with slideways, and each slideway is internally provided with a lifting frame which can slide along the slideway. The rectangular structure of support frame and the parallel both ends of accomodating space length direction are connected with two horizontal telescopic cylinder respectively, and the stiff end of each horizontal telescopic cylinder imbeds respectively in the slide that corresponds with the support frame both sides that accomodate the space width direction parallel, and its flexible end is each other stretched out and is fixed in the both sides that lift up the frame symmetry towards each other, and each horizontal telescopic cylinder is connected with the controller electricity, controls to lift up moving about the width direction of accommodation space (as shown in fig. 4), and two horizontal telescopic cylinder coaxial settings. Correspondingly, two sides of the supporting frame parallel to the width direction of the accommodating space are respectively connected with two longitudinal telescopic cylinders, the fixed ends of the longitudinal telescopic cylinders are respectively embedded into slideways corresponding to two sides of the supporting frame parallel to the length direction of the accommodating space, the telescopic ends of the longitudinal telescopic cylinders mutually extend towards each other and are fixed on two symmetrical sides of the lifting frame, the longitudinal telescopic cylinders are electrically connected with the controller to control the lifting frame to move back and forth in the length direction of the accommodating space, and as shown in fig. 3, the two longitudinal telescopic cylinders are coaxially arranged.
