Abstract
The utility model discloses a safety ladder with a turnable pedal, which comprises a chassis, a tank body arranged on the chassis and a ladder, wherein the two ends of the ladder are respectively and fixedly connected with the top of the left end of the tank body and the left end of the chassis, the ladder is uniformly provided with the pedal, two sides of the bottom end of a first-stage pedal of the ladder are fixedly provided with a trapezoidal connecting plate, the left side of the connecting plate is provided with an arc-shaped hole, the right side of the connecting plate is movably connected with an upright post of the ladder through a rotating shaft, and the upright post of the ladder is provided with a limiting post matched with the arc-shaped hole. When the ladder does not work, the first-stage pedal can be turned over, the second-stage pedal of the ladder stand is higher from the ground, so that people can not climb, non-working people can be effectively prevented from climbing to the top of the tank body, and further danger is prevented.
Description
Technical Field
The utility model relates to a tank type transport vehicle, in particular to an emergency ladder with a turnable pedal.
Background
The tail part of the tank car is generally provided with an escalator for loading and unloading the tank body, so that an operator can conveniently operate the feeding hole at the top of the tank car. Because the tank car is special operation vehicle, in order to avoid non-professional operator or tank car equipment mistake to climb to the jar body when working, it is necessary to set up the safety ladder that a personnel mistake was climbed to avoid tank car work to take place danger.
Disclosure of Invention
The utility model aims to solve the defects and provides a safety ladder with a turnable pedal, which comprises a chassis, a tank body arranged on the chassis and a ladder stand, wherein the two ends of the tank body are respectively and fixedly connected with the top of the left end of the tank body and the left end of the chassis, the ladder stand is uniformly provided with the pedal, two sides of the bottom end of a first-stage pedal of the ladder are fixedly provided with a trapezoidal connecting plate, the left side of the connecting plate is provided with an arc-shaped hole, the right side of the connecting plate is movably connected with an upright post of the ladder stand through a rotating shaft, and the upright post of the ladder stand is provided with a limiting post matched with the arc-shaped hole.
In order to ensure that the turning of the first-stage pedal is more stable and improve the safety of workers when climbing the ladder, the bottom of the connecting plate is movably connected with the piston end of the cylinder, and the other end of the cylinder is arranged on the chassis.
In order to prevent the feet of workers from slipping, anti-slip lines are arranged on the upper surface of the primary pedal.
The utility model has the following beneficial effects: when the ladder does not work, the first-stage pedal can be turned over, the second-stage pedal of the ladder stand is higher from the ground, so that people can not climb, non-working people can be effectively prevented from climbing to the top of the tank body, and further danger is prevented. The cylinder has been installed additional to this design, and the automatic push-and-pull activity footboard of cylinder, mountable cylinder shift knob make opening and closing that the footboard can be nimble freely, and operating personnel during operation key is opened, and the back key is closed after having operated, and it is more convenient to operate, has also improved the security when personnel scramble simultaneously.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is an enlarged view at a in fig. 1.
In the figure: jar body 1, chassis 2, cat ladder 3, one-level footboard 4, cylinder 5, connecting plate 6, spacing post 7, arc hole 8, pivot 9.
Detailed Description
As shown in fig. 1 to 2, a safety ladder with a reversible pedal comprises a chassis 2, a tank body 1 arranged on the chassis 2 and a ladder stand 3 with two ends respectively fixedly connected with the left end top of the tank body 1 and the left end of the chassis 2, wherein the ladder stand 3 is evenly provided with the pedal, two sides of the bottom end of a first-level pedal 4 of the ladder stand 3 are fixedly provided with a trapezoidal connecting plate 6, the left side of the connecting plate 6 is provided with an arc-shaped hole 8, the right side of the connecting plate is movably connected with a stand column of the ladder stand 6 through a rotating shaft 9, and the stand column of the ladder stand column 6 is provided with a spacing column 7 matched with the arc-shaped hole 8.
Further, the bottom of the connecting plate 6 is movably connected with the piston end of the cylinder 5, and the other end of the cylinder 5 is installed on the chassis 2.
Further, the upper surface of the primary pedal 4 is provided with anti-skid lines.
The working principle is as follows: when climbing jar body 1 top in order to prevent the non-staff member, can start cylinder 5, cylinder 5 promotes one-level footboard 4 and revolves 9 clockwise rotation, and at this moment, spacing post 7 plays limiting displacement to one-level footboard 4 through arc hole 7, until the upper surface and the ground vertical of one-level footboard 4. Like this, because the upset of one-level footboard 4, the second grade footboard highly uprises apart from ground, and the climbing jar body just becomes difficult this moment again, can prevent effectively that non-staff from climbing to jar body top. When the staff need climb jar body top, start cylinder 5, the piston end of cylinder 5 is retrieved, and 5 pulling one-level footboard 4 revolute 9 anticlockwise rotations of axle, at this moment, spacing post 7 plays limiting displacement to one-level footboard 4 through arc hole 7, is the horizontality until the upper surface of one-level footboard 4 and ground, and at this moment, because the pulling effect of cylinder 5, the stability of one-level footboard 4 is better, more does benefit to staff's safety.
The above description is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
