Description

Construction elevator chassis device

Technical Field

The utility model relates to a mounting structure of a construction lifter, in particular to a chassis device of the construction lifter.

Background

In general, foundation bolts are embedded in the surface of a foundation, a reinforced concrete foundation is poured on a top plate of a basement, and then a frame and a car of the elevator are installed at the upper part of the foundation. When the basement is under construction, the basement is positioned at the top support reinforcement part of the construction lifter, and the basement needs to be tripped out, so that continuous operation can not be performed; in addition, the cage body of the elevator can be caused to be unbalanced due to the supporting points, so that the potential hazard of serious accidents is easily caused by outward sliding or unbalance of the thrust generated by the load of the supporting chassis of the elevator during the adjustment of the self weight and the operation, and the later dismantling is difficult.

The patent application No. 20080067495. X discloses a construction elevator chassis device and a mounting mode of a standard joint and a chassis. The bottom around the chassis frame (8) is correspondingly welded with a nut (9), the adjusting screw (3) passes through the nut (9), the adjusting screw (3) can move up and down in the nut (9) by rotating the adjusting screw (3), the bottom of the adjusting screw (3) is provided with a base plate (2), and the base plate (2) is locked on the adjusting screw (3) by a locking bolt (10). However, the technology described in the above patent may also have problems that the thrust generated by the load of the elevator support chassis during adjustment of its own weight and operation is slid or unbalanced outward, resulting in serious accident potential and difficult detachment in the later stage.

the cross support is directly and fixedly connected to a basement bottom plate of a building through a plurality of anchor bolts, and a lower standard section of the construction lifter is fixedly connected with the cross support.

As the preferable choice of the construction lifter chassis device, the tail end of the embedded part is provided with a hooked bending.

As the optimization of the construction lifter chassis device, the embedded part of the screw rod is fixedly connected with the binding steel bars in the basement bottom plate.

The construction elevator chassis device does not adopt a basement roof to set a construction elevator foundation and a roof supporting mode is arranged at the lower part, but directly seats the construction elevator on a basement bottom plate, and the bottom of the construction elevator is provided with a cross bracket to be reliably connected with the basement bottom plate before the standard section at the lower side of the construction elevator is installed.

Compared with the traditional reinforced concrete base device, the construction lifter is fixed with a building only by virtue of the construction lifter base device and a plurality of wall attaching pieces, so that the operation stability of special equipment (such as construction lifting and material lifting machines and the like) of the construction engineering is improved, the personal safety of operators can be effectively ensured, the accident occurrence frequency is reduced, and the economic benefit of enterprises can be ensured not to be lost.

The chassis device of the construction elevator cancels the support of the roof of the lower room, thereby being convenient for the construction operation of the basement and the rapid dismantling of the elevator in the later period, and greatly improving the overall safety and stability of the elevator in the running process.
