Abstract

The invention discloses a telescopic boom and ladder bed anti-freezing device applied to elevating fire-fighting trucks, wherein the telescopic boom is a synchronous telescopic boom; a telescopic arm is formed by arranging a four-section arm, a three-section arm, a two-section arm and a one-section arm in a sleeving mode; the four-section arm is positioned at the foremost end of the boom; the one-section arm is hinged with a rotary table through a pin roll; guide blocks are respectively mounted inside the arm head of the one-section arm, inside the arm head of the two-section arm and inside the arm head of the three-section arm; heating belts are arranged outside the arm heads of the one-section arm, the two-section arm and the three-section arm; the position of the heating belt on each arm head is corresponding to that of each guide block; and a power generator on a frame supplies power and heats each heating belt. The telescopic boom and ladder bed anti-freezing device can effectively solve the serious situation that the boom or the ladder bed is difficult to recycle or cannot be recycled due to the fact that the telescopic boom or the ladder bed, which extends out, is frozen due to water spraying during fire extinguishing in winter in the north, so that rescuing and fire extinguishing efficiency is greatly improved.

Description

A kind of telescopic jib and ladder defroster being applied to high lifting kind fire fighting truck

Technical field:

The present invention relates to a kind of telescopic jib and the ladder defroster that are applied to high lifting kind fire fighting truck, exactly belong to fire-fighting and rescue car technical field.

Background technology:

During north of china in winter, during high lifting kind fire fighting truck fire fighting and rescue, to pour the adhesion that jib or ladder causes arrive because water freezes between jib or ladder integral for water, regain difficulty maybe cannot regain, this just adds certain difficulty to fire fighting and rescue, reduce rescue efficiency, severe patient also can become relieved object, therefore to the research of the telescopic jib being applied to high lifting kind fire fighting truck that can satisfy the demands and ladder defroster and design also more and more urgent.

Current high lifting kind rescue type fire fighting truck does not adopt jib or ladder heating technique to solve the problem.

Summary of the invention:

For overcoming the defect of prior art, the object of the present invention is to provide a kind of telescopic jib and the ladder defroster that are applied to high lifting kind fire fighting truck.

Technical solution problem of the present invention adopts following technical scheme:

A kind of telescopic jib and ladder defroster being applied to high lifting kind fire fighting truck, described telescopic jib is synchronization telescope jib, overlapped successively dressed up telescopic arm by four joint arms, three joint arms, two joint arms, a joint arm, described four joint arms are in jib foremost, a described joint arm and turntable pass through hinge, guide block is separately installed with inside a joint arm arm head, inside two joint arm arm heads, inside three joint arm arm heads, and have heating tape in a joint arm, two joint arms, three joint arm arm head outer setting, on each arm head the position of heating tape and the position of guide block corresponding; Each described heating tape is heated by the generator powered on vehicle frame.

Guide block on each arm head is arranged on four corner location inside arm head, and the guide block and two of a joint arm saves arm arm figure and becomes to roll or sliding friction; The guide block and three of two joint arms saves arm arm figure and becomes to roll or sliding friction; The guide block and four of three joint arms saves arm arm figure and becomes to roll or sliding friction.

Compared with the prior art, beneficial effect of the present invention is embodied in:

When the present invention effectively can solve north of china in winter fire-fighting fire extinguishing, telescopic jib or ladder stretch out rear being frozen in because of trickle and cause jib or ladder to regain difficulty or nonrecoverable serious conditions, greatly improve rescue efficiency.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention; Fig. 2 is guide block arrangement schematic diagram.

Number in the figure: 1 four joint arms, 2 three joint arms, 3 two joint arms, 4 one joint arms, 5 turntables, 6 are got off, 7 generators, 8 heating tape three, 21, heating tape two, 10, heating tape one, 9 guide block one, 31 guide block two, 41 guide blocks three.

Below by way of detailed description of the invention, and the invention will be further described by reference to the accompanying drawings.

Detailed description of the invention, non-limiting examples is as described below:

Embodiment: see accompanying drawing, the present embodiment is applied to telescopic jib and the ladder defroster of high lifting kind fire fighting truck, for four joint synchronization telescope jibs, by four joint arms 1, three joint arms 2, two joint arms 3, one joint arm 4 overlaps successively dresses up telescopic arm, four joint arms 1 are in jib foremost, one joint arm 4 passes through hinge with turntable, turntable 5 is located at gets off on 6, inside the arm head of a joint arm 4, inside the arm head of two joint arms 3, guide block is separately installed with inside the arm head of three joint arms 2, and at a joint arm, two joint arms, three joint arm arm head outer setting have heating tape, on each arm head the position of heating tape and the position of guide block corresponding, each heating tape supplies electrical heating by the generator 7 on vehicle frame (getting off).

Shown in Fig. 2, guide block on each arm head is arranged on four corner location inside arm head, be specially: guide block 1 is positioned at four corner location inside joint arm 4 arm head, guide block 2 31 is positioned at four corner location inside two joint arm 3 arm heads, guide block 3 21 is positioned at four corner location inside three joint arm 2 arm heads, and the motion between the arm body that guide block 1 and two saves arm 3 is for slide or to roll; Motion between the arm body that guide block 2 31 and three saves arm 2 is for slide or to roll; Motion between the arm body that guide block 3 21 and four saves arm 3 is for slide or to roll;

In specifically arranging, heating tape 1 is installed on position corresponding to the arm head guide block of a joint arm 4, heating tape 29 is installed on position corresponding to the arm head guide block of two joint arms 3, heating tape 3 10 is installed on position corresponding to the arm head guide block of three joint arms 2, generator 7 provides electric power to make it generate heat for each heating tape, by the ice-out freezed between each joint telescopic arm and guide block, telescopic arm is stretched out or regains smooth and easy without hindrance.

Foregoing is only preferred embodiments of the present invention, and does not lie in restriction patent of the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
