Abstract
The utility model provides a shelter is with turning over a commentaries on classics cat ladder of stepping on, turns over a short ladder including fixed long ladder, with fixed long ladder articulated, turns over when turning over a short ladder and fixed long ladder through the hasp, and fixed long ladder upper end is connected with the footboard, has the handrail on the footboard, the handrail is including being located the left handrail of footboard, being located the footboard right side and being fixed in the right handrail of shelter top surface. The invention solves the problem of the distance between the crawling ladder and the chassis by changing the two-section type turnover crawling ladder, also shortens the integral ground clearance of the crawling ladder and is convenient for operators to climb. The operator can easily finish horizontal rotation by 90 degrees through the pedals and the handrails when quickly climbing to the pedal position at the top of the shelter from bottom to top or climbing to the pedal from the top surface of the shelter from bottom to top.
Description
Technical Field
The invention relates to a ladder stand.
Background
The ladder of climbing the top mainly climbs to the rescue car roof as operating personnel and carries out the annex and get and put and the operation usefulness such as overhaul of the equipments, and traditional cat ladder adopts single-row vertical ladder formula, because there are urea jar, oil tank etc. to block rescue car cat ladder lower part, cat ladder and chassis interval can't satisfy detection standard, inconvenient operating personnel climbing.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the turning ladder for the shelter, which is reasonable in structure, safe and reliable.
The technical scheme of the invention is as follows: including fixed long ladder, with fixed long ladder articulated turn over a short ladder, turn over when turning over a short ladder and fixed with fixed long ladder through the hasp, fixed long ladder upper end is connected with the footboard, has the handrail on the footboard, the handrail is including being located the left handrail of footboard, being located the right handrail of footboard right side and being fixed in the shelter top surface.
The top surface of the left handrail is higher than the top surface of the right handrail.
The left handrail is a ladder top arch handrail and consists of two vertical pipe sections and an L-shaped pipe section connected between the two vertical pipe sections.
The right handrail is a side U-shaped handrail and is of an inverted U-shaped structure consisting of two vertical pipe sections and a horizontal pipe section connected between the two vertical pipe sections.
The fixed long ladder and the folding short ladder are formed by welding square steel tubes and are provided with a plurality of sections of step ladders, the step surfaces on the step ladders are provided with anti-skid holes, and the square steel tubes on the right side of the fixed long ladder are fixed with the front end surface of the shelter.
And the pedal is provided with an anti-skid hole.
The lower part of the fixed long ladder is provided with a rubber cushion pad which is elastically supported when the turnover short ladder is turned down.
The name of the invention explains: the operating personnel climb up and down on the side surface of the shelter by using the shelter fingers; the folding finger section is folded forwards and downwards; the turning climbing finger quickly climbs to the pedal position at the top of the shelter from bottom to top or horizontally turns 90 degrees when climbing to the pedal from the top surface of the shelter from bottom to top; the ladder climbing means climbing up and down the shelter.
The folding short ladder is generally used for the front side surface of a vehicle-mounted shelter, so that an operator can climb to the top of a carriage to complete top accessory taking and placing and equipment maintenance, and at ordinary times, the folding short ladder is locked by a hasp after being folded upwards, so that the situation that people are injured in the first folding process and people are scratched in the second folding process when the shelter is used for driving an automobile chassis is avoided; after the folding short ladder is turned upwards, the oil tank at the lower part of the carriage is convenient to fill, and meanwhile, the passing performance is improved due to the fact that the part below the ladder stand is far away from the ground; if the short ladder needs to be lifted up after parking, the hasp is unlocked, the turnover short ladder is turned down, the back face of the turnover short ladder is elastically supported by the rubber cushion pad, and an operator holds the square steel tubes on the two sides of the ladder and climbs the turnover short ladder and the fixed long ladder to the pedals and then turns and climbs 90 degrees to the top face of the shelter (the arched handrails on the top face of the hand ladder and the U-shaped handrails on the side faces when the short ladder is close to the top face). At the initial stage just after the top surface of the shelter is started, when an operator steps on pedals from the top surface of the shelter, the operator holds the arch-shaped handrail on the top of the ladder, turns back to face outwards, faces the front part of the shelter (the ladder), holds the lower part of the arch-shaped handrail on the top of the ladder, holds the U-shaped handrail on the side face on the right side, slowly climbs downwards along the ladder, climbs to a fixed long ladder and turns over a short ladder, controls the square steel tube to the ground when turning over the short ladder, and then turns over the short ladder upwards and turns over the short ladder and then the short ladder is.
The invention solves the problem of the distance between the crawling ladder and the chassis by changing the two-section type turnover crawling ladder, also shortens the integral ground clearance of the crawling ladder and is convenient for operators to climb. The operator can easily finish horizontal rotation by 90 degrees through the pedals and the handrails when quickly climbing to the pedal position at the top of the shelter from bottom to top or climbing to the pedal from the top surface of the shelter from bottom to top.
The arrangement of the left handrail is convenient for operators to support in the initial stages of climbing to the top of the compartment and descending and when the pedals are turned to ascend; the pedal with one pedal distance from the top of the carriage is arranged, so that a space for turning 90 degrees is formed when the pedal turns from a ladder to the top of the carriage after climbing up and down to the top of the carriage, and the pedal is more humanized; meanwhile, the top edge of the front side of the carriage on the right side of the arched handrail on the ladder top is provided with the side U-shaped handrail, so that the convenience of switching between the ladder and the carriage top is reflected again; the folding short ladder is folded up and down.
Drawings
Fig. 1 is one of the structural schematic diagrams of the present invention (the folding short ladder is in an up-folding state).
Fig. 2 is a second usage state diagram of the present invention (the folding short ladder is in a downward folding state).
