Description

Multifunctional construction early warning ladder

Technical Field

The utility model relates to an engineering equipment field especially relates to a multi-functional construction early warning ladder.

Background

Ladders are common tools used in daily life and engineering construction for climbing heights. Because workers need to stand at the high place of the ladder for operation, the safety of the ladder is important, particularly in various engineering construction projects, the environment of a construction site is complex, the workers standing on the ladder often need to carry tools with large size and weight for long-time operation, and the safe and stable ladder is related to the life safety of the workers. Most ladder structures in the prior art are very simple, an effective safety structure is lacked, a lot of construction units need to additionally configure a worker to hold the ladder beside to improve safety, manpower resources are wasted, and engineering cost is increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a novel have prevent empting, antiskid, prevent the ladder of multiple functions such as electric.

In order to solve the technical problem, the utility model discloses a technical scheme does: a multifunctional construction early warning ladder comprises upright posts and a cross rod, wherein two ends of the cross rod are respectively connected to the two upright posts, and a support rod, a ratchet wheel, a pawl and a torsion spring are arranged in each upright post;

the support rod is connected with a ratchet wheel, and the ratchet wheel is hinged with the upright post;

the pawl is hinged with the upright post, the torsion spring drives the pawl to be buckled on the one-way teeth of the ratchet wheel, and a rotary knob is arranged on a rotary shaft of the pawl.

The bracing piece prevents empting for the ladder provides extra support, and specific use is:

(1) the ladder is obliquely erected on other structures, the support rod is rotated to enable the support rod to be parallel to the ground, and the ratchet wheel and pawl structure limits the rotation of the support rod;

(2) after the ladder is used, the pawl is rotated by the knob, so that the pawl is separated from the ratchet wheel, then the supporting rod is rotated, and the supporting rod is recycled to the inside of the upright post.

Further, the top of the upright post is hinged with a hook; under conditional conditions, the ladder can be hung on the structure by utilizing the hook, and the safety is further improved.

Further, the surface of stand is provided with the reflector layer, and when the workman was in near road operation, the reflector layer can be noticed by vehicle or pedestrian more easily on the ladder, reminds other people to notice and dodges.

Further, nearly electric alarm ware is installed at the top of stand, and when the electric shock was dangerous, nearly electric alarm ware can send out police siren sound and carry out the early warning, and constructor knows the electrified condition of construction environment in advance, and the emergence of effectual prevention electric shock accident guarantees constructor personal safety.

Furthermore, the surface of the upright post is provided with scales, so that workers can visually know the specific height condition conveniently.

Furthermore, the bottom of the upright post is provided with an anti-skid layer.

Furthermore, the bottom of the upright post is provided with a turnover roller.

Has the advantages that: (1) the utility model discloses an early warning ladder is provided with the bracing piece that can rotate in the stand, and when the early warning ladder used, the workman can put down the bracing piece by oneself and provide extra support for the early warning ladder, avoids the early warning ladder to empty, improves the security. (2) The utility model discloses an early warning ladder sets up nearly electric alarm at the stand top, in time reminds workman construction environment's electrified condition, prevents the electric shock accident. (3) The utility model discloses an early warning ladder sets up the reflector layer on the stand surface, avoids vehicle and pedestrian to hit the early warning ladder because of the sight is not enough by mistake.

Wherein: 1. a column; 2. a cross bar; 3. a support bar; 4. a ratchet wheel; 5. a pawl; 6. a torsion spring; 7. a knob; 8. hooking; 9. a near electric alarm; 10. a light-reflecting layer; 11. a wall.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1 to 3, the multifunctional construction early warning ladder of the present embodiment includes upright columns 1 and a cross bar 2, two ends of the cross bar 2 are respectively connected to the two upright columns 1, and a support rod 3, a ratchet 4, a pawl 5 and a torsion spring 6 are arranged in the upright columns 1;

the support rod 3 is connected with a ratchet 4, and the ratchet 4 is hinged with the upright post 1;

as shown in figure 3, the pawl 5 is hinged with the upright post 1, the torsion spring 6 drives the pawl 5 to be buckled on the one-way teeth of the ratchet 4, and a rotary shaft of the pawl 5 is provided with a knob 7.

The top of the upright post 1 is hinged with a hook 8 and is provided with a near electric alarm 9, and the surface of the upright post 1 is provided with scales for indicating the height and a reflective layer 10.

The early warning ladder of this embodiment utilizes bracing piece 3 to provide extra support and prevents empting, and specific use is:

(1) the ladder is obliquely erected on a wall 11 as shown in figure 1, the support rod 3 is rotated to enable the support rod 3 to be parallel to the ground, and the ratchet wheel 4 and the pawl 5 structure limit the rotation of the support rod 3;

(2) after the ladder is used, the pawl 5 is rotated by the knob 7, so that the pawl 5 is separated from the ratchet wheel 4, then the support rod 3 is rotated, and the support rod 3 is recovered to the inside of the upright post 1.
