Abstract
The utility model discloses a fixed folding ladder is used in fire engine carriage, it includes main bench, vice bench, spring catch device, snubber block, antiskid foot bar. The main ladder section and the auxiliary ladder section are connected through a hinge, and the spring pin device is installed on the main ladder section. The main ladder section is fixed behind the fire truck carriage. The folding ladder needs small installation space and can be installed on a fire truck needing to climb a carriage. And occupies a small space when being in a folded state.
Description
Technical Field
The utility model relates to a fire-fighting equipment field, concretely relates to fire engine carriage is with fixed folding ladder.
Background
Because the fire engine box is higher, the fighter need set up the ladder when climbing box platform. And the installation space on the box body is relatively small, which is not satisfied with the installation of the common ladder.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a collapsible climbing device to current equipment's not enough, it can solve the ladder and leave the problem that the ground height can't satisfy the requirement.
In order to achieve the aim, the utility model provides a fire engine carriage is with fixed folding ladder, including main bench, vice bench, spring catch device, snubber block, antiskid foot bar. The main ladder section is connected with the auxiliary ladder section through a hinge.
Preferably, the anti-skid foot bar is rectangular.
Preferably, spring pin devices are arranged on two sides of the main ladder section.
Preferably, when the folding ladder is in a folding state, the limiting holes act on the spring pin devices arranged on two sides of the main ladder section, so that the auxiliary ladder sections are relatively fixed. The auxiliary ladder section is positioned in a plane parallel to the main ladder section.
Preferably, when the folding ladder is in the working state, the auxiliary ladder section and the main ladder section are in the same plane, and particularly, the auxiliary ladder section is suspended at the lower end of the main ladder section in a hinged mode.
The utility model adopts the above technical scheme after, the advantage that has is that required installation space is little, the mechanical part that adopts is with low costs, spare part is convenient for maintain and change.
Drawings
Fig. 1 is the folding state schematic diagram of the fixed folding ladder for the fire engine compartment.
Fig. 2 is the utility model discloses the operating condition schematic diagram of fire engine carriage is with fixed folding ladder.
Fig. 3 is a partial view of a hinge.
Fig. 4 is a partial view of the spring pin assembly installation.
In the drawings: 1. the anti-skidding foot bar 2, the main ladder section 3, the auxiliary ladder section 4, the spring pin device 5, the shock absorption block 6 and the limiting hole.
Detailed Description
When the utility model discloses be in fold condition, spring catch 4 is restricted and is set up in the spacing downthehole of main bench 1. When the spring pin 4 is pulled out, the auxiliary ladder section is turned downwards by 180 degrees to reach the maximum turning value, and the auxiliary ladder section 3 impacts the damping block 5. After the battle is finished, the auxiliary ladder section is turned upwards by 180 degrees, so that the auxiliary ladder section is tightly attached to the main ladder section. The spring pin 4 is inserted into a limit hole arranged on the auxiliary ladder section. At this time, the folding ladder is in a folded state.
The shock absorption block 5 can play a shock absorption role and reduce the impact on the main ladder section 2 when the auxiliary ladder section 3 falls. Effectively reduce the wearing and tearing of vice bench 3 and main bench 2.
The tail end of the auxiliary ladder section 3 is tilted outwards, so that the folding operation is convenient.
