Detailed Description

The utility model discloses a construction project construction double ladder is an instrument that uses among the building engineering, especially uses when indoor construction or fitment. The utility model discloses in fact be to an improvement of current double ladder, through increasing functional unit, need frequently reciprocate the problem that work efficiency is low that leads to in the solution double ladder use to improve double ladder's performance. The present invention will be described in further detail with reference to the following drawings and specific embodiments:

the utility model relates to a double ladder that building engineering construction was used is the improvement to current double ladder. As shown in fig. 1 and 2, the herringbone ladder mainly comprises a working platform 1 and two ladder frames 2 which are hinged with the working platform 2. Two ladder frames 2 are oppositely arranged and hinged at opposite ends of the work platform 1.

In order to enable the herringbone ladder to move under the condition that a user does not need to get off the ladder, a moving device and an expansion bracket are correspondingly arranged. Specifically, an expansion bracket is fixedly arranged in the middle of the lower end face of the working platform 1, and then a moving device is fixedly arranged at the lower end of the expansion bracket.

As shown in fig. 1 and 2, the telescopic frame includes a rectangular bracket 3 fixed on the lower end surface of the working platform 1 and a plurality of adjusting electric cylinders 4 fixed on the lower end surface of the rectangular bracket 3. In general, the electric adjustment cylinders 4 are provided in four numbers and are respectively located at four corners of the rectangular bracket 3. The four adjusting electric cylinders 4 can ensure stable support of the telescopic frame. The rectangular support 3 is preferably fastened to the work platform 1 by means of a detachable connection, for example by means of bolts. If the rectangular support and the moving device part are not adopted, the ladder can be used as a common herringbone ladder.

The moving device comprises a walking plate 7 and a plurality of groups of moving rollers 5 which are hinged on the lower end surface of the walking plate 7. A moving motor 6 is also arranged on the walking plate 7, wherein a group of moving rollers 5 is driven by the moving motor 6 to rotate, and the group of moving rollers 5 is used as a driving wheel. The output shaft of the moving motor 6 transmits power to the moving roller 6 through gear transmission, which is a common transmission mode and is directly utilized. A battery is also provided on the running plate 7 to supply electric power to the moving motor 6 and the adjusting electric cylinder 4. Because the movement of the herringbone ladder in the using process belongs to micro movement, the power supply of the storage battery can meet the requirement. In order to reduce the work load of the moving motor 6 when the herringbone ladder is driven to move, the working platform 1, the ladder frame 2, the rectangular support 3 and the walking plate 7 are all made of aluminum alloy or aluminum magnesium alloy, and the overall quality is reduced. The storage battery is preferably a lithium battery, so that the battery has large capacity and light weight.

As shown in fig. 1 and 2, the traveling plate 7 is fixedly connected to the telescopic end of the adjustment cylinder 4, and the electric adjustment cylinder 4 can move the traveling plate 7 up and down by the movement of the telescopic end. When the walking plate 7 is required to drive the herringbone ladder to move integrally, the electric adjusting cylinder 4 extends downwards to enable the moving rollers 7 on the walking plate 7 to be in contact with the ground, the lower ends of the two ladder frames 2 are separated from the ground due to further extension of the electric adjusting cylinder 4, then the moving motor 6 is controlled to output power outwards, and the walking plate 7 drives the whole herringbone ladder to move. When the movement is finished, the electric adjusting cylinder 4 is recovered, so that the two ladder frames are in contact with the ground to support the human body ladder, the walking plate 7 is in a suspended state, and the herringbone ladder is stably supported on the ground. The moving motor 6 can be controlled remotely, which is a remote control technique of the motor, for example, on the control of a crown block, or the control of a child toy car. The herringbone ladder is used in putty scraping during decoration, and frequent ascending and descending of the ladder are not needed any more.

This double ladder has set up work platform 1, and the user can sit work at work platform 1, also can place some necessary instruments on work platform 1. And the circumference of the upper end surface of the working platform 1 is provided with the handrail 8.

The utility model discloses a double ladder has set up mobile device and has used the expansion bracket to connect mobile device with the main part of double ladder, and the expansion bracket can control mobile device's level, makes mobile device can be unsettled or contact ground and carries out work. This double ladder can remove conveniently, and does not need the user to go up and down the ladder, can improve work efficiency to guarantee safety. Although the telescopic frame, the adjusting electric cylinder, the walking plate and the moving motor in the herringbone ladder are additionally provided with parts of the herringbone ladder, the manufacturing cost is improved, the construction efficiency of the construction engineering can be improved on the whole, and the personal safety is ensured, so that the construction cost is reduced on the whole.

The utility model discloses in the in-service use, it is very convenient, the functional.
