Abstract

A mechanical elephant trunk scaling ladder is a telescopic mechanical elephant trunk scaling ladder formed by the mutual nesting of a plurality of rigidity tubes. A motor (5) is used to drive a gear (6) to move a rack (3) up and down, therefore, the mechanical elephant trunk scaling ladder can be fast extended. The mechanical elephant trunk scaling ladder can be extended to a disaster point when fires occur, and victims can escape fast along elephant trunks formed by connecting cannulas (1) of the mechanical elephant trunk scaling ladder and support arms (10). The mechanical elephant trunk scaling ladder has the advantages of fast rescue speed, convenient use, excellent and significant effect, greatly increases the rescue effect, and is suitable for the firefighting rescue.

Description

Machinery elephant trunk aerial ladder

Technical field

The utility model relates to the device of fire fire-fighting and rescue, relates in particular to a kind of mechanical elephant trunk aerial ladder.

Background technology

When the high-rise breaking out of fire,, use telescopic mechanical arm aerial ladder rescue usually because lower intensity of a fire shutoff escape way makes the eminence masses suffering from disaster be difficult to escape.Because mechanical arm is flexible and promote the withdrawal process need time, speed is slower, influences rescue speed, and the safeguard station space is limited, the general maximum 5-6 people of the number of once succouring, and sometimes because of smog and injured influence, the disaster affected people inconvenient activity increases the rescue difficulty.At present, though to the improvement of aerial ladder and form corresponding utility model and patent of invention more, as slide formula ambulance (patent No. is ZL200420036311.6) etc., rescue speed still makes little progress, effect is not ideal.

The utility model content

The purpose of this utility model is to provide a kind of mechanical elephant trunk aerial ladder, to improve fire-fighting and rescue speed, alleviates personnel and injures the pain of injury.

The technical solution of the utility model is a kind of mechanical elephant trunk aerial ladder, it comprises support arm, hydraulic pressure strut and telescopic arm, it is characterized in that described telescopic arm is made up of mutually nested multilayer sleeve 1, each sleeve pipe 1 both sides is protruded and is constituted ear groove 2, outside the ear groove 2 of the sleeve pipe 1 of innermost layer, tooth bar 3 is installed, top is equipped with motor gearbox 4 outside other the ear groove 2 of sleeve pipe 1, motor 5 and gear 6 are arranged in the motor gearbox 4, motor gearbox 4 times is installed tooth bar 3, and the tooth bar 3 on the sleeve pipe 1 ear groove 2 of gear 6 and its internal layer is meshed; Multilayer sleeve 1 is nested in the support arm 10, and support arm 10 also also has two ear grooves 2 for cylinder structure, and two ear grooves, the 2 outer tops of support arm 10 also are equipped with motor gearbox 4, and motor 5 and gear 6 are arranged in it, and the tooth bar 3 on the sleeve pipe 1 ear groove 2 of gear 6 and its internal layer is meshed.

By motor 5 driven gears 6 tooth bar 3 is moved up and down, thus flexible rapidly mechanical elephant trunk aerial ladder.It is the retractility machinery elephant trunk aerial ladder with the mutually nested formation of a plurality of rigidity tubing.During breaking out of fire, mechanical elephant trunk aerial ladder is elongated to calamity point place, masses suffering from disaster just can down sneak away rapidly along each sleeve pipe 1 of mechanical elephant trunk aerial ladder and the elephant trunk that support arm 10 is connected to form, thereby improve rescue speed greatly.Machinery elephant trunk aerial ladder rescue inclination angle can not waited from 35 ° to 60 °.For ensureing the reliable and safety of mechanical elephant trunk aerial ladder operation, mechanical elephant trunk aerial ladder is equipped with travel switch.

The utility model has the advantages that rescue speed is fast, easy to use, respond well and obvious, improved the rescue effect greatly.

The utility model is applicable to fire-fighting and rescue.

The specific embodiment

Further specify as follows in conjunction with the accompanying drawings:

As shown in Figure 1, the technical solution of the utility model is a kind of mechanical elephant trunk aerial ladder, and it comprises support arm 10, hydraulic pressure strut 7 and telescopic arm, it is characterized in that described telescopic arm is made up of mutually nested multilayer sleeve 1;

As shown in Figure 2, each sleeve pipe 1 both sides is protruded and is constituted ear groove 2;

As Fig. 1, shown in Figure 3, outside the sleeve pipe 1 ear groove 2 of innermost layer, tooth bar 3 is installed, top is equipped with motor gearbox 4 outside other the ear groove 2 of sleeve pipe 1, motor 5 and gear 6 are arranged in the motor gearbox 4, motor gearbox 4 times is installed tooth bar 3, and the tooth bar 3 on the sleeve pipe 1 ear groove 2 of gear 6 and its internal layer is meshed; Multilayer sleeve 1 is nested in the support arm 10, and support arm 10 also has two ear grooves 2, and two ear grooves, the 2 outer tops of support arm 5 also are equipped with motor gearbox 4, and motor 5 and gear 6 are arranged in the motor gearbox 4, and the tooth bar 3 on the sleeve pipe 1 ear groove 2 of gear 6 and its internal layer is meshed;

Fig. 4 is the mechanical elephant trunk aerial ladder fire-fighting and rescue car schematic diagram of the utility model specific embodiment, rotating disk 8 is installed on the fire-fighting and rescue car, mechanical elephant trunk aerial ladder is installed on rotating disk 8, regulate the height of mechanical elephant trunk aerial ladder with hydraulic pressure strut 7, when implementing rescue, make tooth bar 3 elongations by motor 5 driven gears 6, after mechanical elephant trunk aerial ladder is tapped to fire high building eminence appropriate location, masses suffering from disaster just can be along down sneaking away rapidly in each sleeve pipe 1 of mechanical elephant trunk aerial ladder and the elephant trunk that support arm 10 is connected to form, skid off from the elephant trunk lower end, after slipping into the fire fighting truck chute, hole 9 falls into air cushion 11, escape unharmed through connecing to slip.
