Abstract
The utility model discloses a kind of removable ladder-type fire-fighting truntable ladder, including car body, bracket, amplitude oil cylinder, bracket, telescopic oil cylinder and ladder, one end of bracket is hinged on bracket, the bracket other end is connect by amplitude oil cylinder with bracket, and the position of the stroke control bracket of amplitude oil cylinder is utilized;It is slidably connected between bracket and ladder, one end of telescopic oil cylinder is fixed on the other end on bracket and is fixed on ladder, ladder is driven to slide on bracket by the movement of telescopic oil cylinder, meet from vehicle running state to ladder working condition, this programme solves because bracket and bracket can adjust position according to vehicle's center of gravity requirement, while meeting vehicle axle load requirement, the performance of fire-fighting truntable ladder is not influenced;The ride-height of vehicle can be reduced;Under vehicle equal conditions, mobile ladder can increase operation amplitude and operation height relative to fixed ladder;Under vehicle running state, rescue personnel is facilitated to enter directly into workbench from ground.
Description
Technical field
The utility model relates to a kind of aerial ladder bracket of used in fire-fighting, especially a kind of removable ladder-type aerial ladder fire-fighting
Vehicle.
Background technique
In existing fire-fighting truntable ladder, the position between bracket and ladder be it is relatively-stationary, such structure is at certain
There are some functions can not achieve under a little vehicle restrictive conditions, for example fire-fighting truntable ladder ride-height is required very in some requirements
Low, vehicle can cannot pass through driver's cabin top, front ladder by most of limit for height sections in order to meet requirement for height ladder
Frame structure can not just arrange, therefore ladder length will be limited, but operation height and operation amplitude can't change, then ladder
The limitation requirement of full car length and vehicle's center of gravity can only be solved again towards rear portion, back space, this results in existing design very
Difficulty is met the requirements.
In addition in existing technology, after fire fighter needs first upper roof, just can enter in workbench, to waste
A large amount of rescue time.
Utility model content
The technical assignment of the utility model is to be directed to the above the deficiencies in the prior art, and provide a kind of removable ladder-type cloud
Terraced fire fighting truck.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the utility model discloses one kind to move
Ladder-type fire-fighting truntable ladder, including car body, bracket, amplitude oil cylinder, bracket, telescopic oil cylinder and ladder, the one of the bracket
End is hinged on bracket, and the bracket other end is connect by amplitude oil cylinder with bracket, controls bracket using the stroke of amplitude oil cylinder
Position;It is slidably connected between the bracket and ladder, one end of the telescopic oil cylinder is fixed on the other end on bracket and is fixed on ladder
On frame, ladder is driven to slide on bracket by the movement of telescopic oil cylinder.
Be further improved: triangle, one end of the amplitude oil cylinder are hinged at the obtuse angle of bracket the bracket in obtuse angle,
The other end of the amplitude oil cylinder is hinged on the front end of bracket, and the end of the bracket and the vertex of the bracket are hinged.
It is further improved: being equipped with sliding slot on the bracket, the sliding block cooperated with the sliding slot is equipped on the ladder.
The advantages of the utility model: 1. because bracket and bracket can require according to vehicle's center of gravity and adjust position, full
While sufficient vehicle axle load requires, the performance of fire-fighting truntable ladder is not influenced.2. the ride-height of vehicle can be reduced.3. in vehicle
Under equal conditions, mobile ladder can increase operation amplitude and operation height relative to fixed ladder.4. in vehicle driving
Under state, rescue personnel is facilitated to enter directly into workbench from ground.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the connection schematic diagram of the utility model ladder and bracket.
Fig. 3 is the position view of the utility model fire fighting truck ladder when driving.
Fig. 4 is the position view before the stretching, extension of the utility model ladder.
Fig. 5 is the position view of ladder when the utility model fire fighter enters workbench.
Headstock 1, car body 2, bracket 3, amplitude oil cylinder 30, bracket 4, telescopic oil cylinder 40, sliding slot 41, ladder 5, sliding block 51, work
Make platform 6.
Specific embodiment
The utility model is described below with reference to the accompanying drawings of the specification.
As shown, a kind of removable ladder-type fire-fighting truntable ladder, including car body 2, bracket 3, amplitude oil cylinder 30, support
One end of frame 4, telescopic oil cylinder 40 and ladder 5, the bracket 4 is hinged on bracket 3, and 4 other end of bracket passes through amplitude oil cylinder 30
It is connect with bracket 3, utilizes the position of the stroke control bracket 4 of amplitude oil cylinder 30;It is slidably connected between the bracket 4 and ladder 5,
One end of the telescopic oil cylinder 40 is fixed on the other end on bracket 4 and is fixed on ladder 5, is driven by the movement of telescopic oil cylinder 40
Ladder slides on bracket.
Triangle, one end of the amplitude oil cylinder 30 are hinged at the obtuse angle of bracket 3 bracket 3 in obtuse angle, the change
The other end of width oil cylinder 30 is hinged on the front end of bracket 4, and the end of the bracket 4 and the vertex of the bracket 3 are hinged;Institute
Bracket 4 is stated equipped with sliding slot 41, the sliding block 51 cooperated with the sliding slot 41 is equipped on the ladder 5.
Its working principle is that: firstly, the bottom end of ladder 5 is located at entire vehicle at this time in fire fighting truck normally travel (such as Fig. 3)
The front end of body 2, the top of ladder 5 are located at the end of entire car body 2, and workbench 6 is located at the front end of ladder 5, though at this time
The length of right ladder 5 is increased compared to before, but the length of entire car body 2 does not increase, additionally, due to the bottom end of ladder 5
At headstock 1, so ladder 5 is to be unable to complete stretching, extension work in this case.
When fire fighting truck, which reaches scene, to be rescued, the elongation of hydraulic cylinder 40 is shunk by control to drive ladder first
5 slide on bracket 4, slide so that ladder 5 is whole to the end of car body 2, when the bottom end of ladder 5 slides into the front end of bracket 4
When (such as Fig. 4), at this time by control amplitude oil cylinder 30 extend, ladder 5 is erected, to meet the rescue need of fire fighter
It asks.
Fire fighter is when entering workbench 6, by controlling the shortening of amplitude oil cylinder 30, so that the top position of ladder 5
Reduction (such as Fig. 5) is set, so that fire fighter be facilitated quickly to enter in workbench 6.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
