A standardized elevator shaft operating platform

Abstract

The utility model relates to the field of elevator shaft construction equipment, and in particular to a standardized elevator shaft operating platform, including a platform frame, a ladder frame arranged below the platform frame, and a protective mechanism. Since one end of the device mounting the ladder frame is heavy, the entire device will be offset when the device is hoisted. At this time, by setting a protective cover, even if the four corners of the platform frame hit the building structure due to the offset of the device, it can avoid the situation where the building structure and the device are seriously damaged after the device hits the building structure, and after the collision, the device may swing. By setting the roller, when the bottom of the device hits the building structure, the possibility of damage to the device or the building structure can be reduced, and before the device is fixed and installed, the swivel can be twisted to move the swivel upward, and then the lifting ring is lifted upward to make the insertion rod disengage from the circular hole at the upper end of the mounting frame, and the mounting frame is rotated 90° so that the roller does not affect the installation and fixation of the device.

Description

Technical Field

[0001] The utility model relates to the field of elevator shaft construction equipment, in particular to a standardized elevator shaft operating platform. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

[0003] When installing the elevator and necessary structures in the elevator shaft, an elevator shaft operating platform is generally required to assist in the installation.

[0004] Most of the existing standardized elevator shaft operating platforms are triangular structures when viewed from the side, and the buildings where elevators are installed are generally high-rise buildings. Therefore, lifting equipment such as cranes are used to transport the platforms to the floors. Since the operating platforms are mostly triangular structures, the center of gravity of the platforms is likely to shift to the side with more structures after being lifted. This makes it easy for the lifted platform to hit the outer wall of the building or the inner wall structure of the elevator shaft, which can easily cause damage to the inner wall structure of the elevator shaft, the outer wall of the building, and the operating platform. Utility Model Content

[0005] The purpose of the utility model is to provide a standardized elevator shaft operating platform in order to solve the above-mentioned problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A standardized elevator shaft operating platform comprises a platform frame, a ladder frame is arranged below the platform frame, and a protection mechanism;

[0008] The protection mechanism includes a screw rod. The lower ends of the two pillars of the ladder frame are fixed with screw rods. The lower ends of the screw rods are rotatably connected to a mounting frame. The middle of the mounting frame is rotatably connected to a roller. The outer periphery of the screw rod is threadedly connected to a swivel. A lifting ring is arranged below the swivel, and the inner circle of the lifting ring is larger than the outer circle of the screw rod. Insertion rods are fixed to the lower ends of the four quadrants of the lifting ring. Circular holes are opened on the upper end surface of the mounting frame at the positions corresponding to the four insertion rods, and protective covers are fixed at the four corners of the platform frame.

[0009] Preferably, the outer ring of the roller is made of rubber, and the lower end of the insertion rod is rounded.

[0010] Preferably, the protective cover is made of rubber and has a thickness of three centimeters.

[0011] Preferably: two cross beams are fixed at the bottom of the platform frame, an auxiliary beam is fixed in the middle of the cross beams, two lifting rings are integrally formed at the upper end of the platform frame, and the ladder frame is fixed to the lower end of one side of the two cross beams by bolts.

[0012] Preferably: two oblique rods are fixed to one end of the ladder frame by bolts, and the upper ends of the two oblique rods are respectively fixed to the lower ends of the other sides of the two beams by bolts, and two storage grooves are opened at the lower part of the other end of the ladder frame, and the clamping structure is installed inside the storage grooves.

[0013] Preferably, the clamping structure comprises two clamping strips, which are rotatably connected to the inside of the two receiving slots respectively, a magnet is fixed to the lower end of the clamping strip, and a groove is formed at the upper end of the clamping strip.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] Since one end of the device installation ladder is heavier, the entire device will be offset when the device is lifted. At this time, through the provision of the protective cover, even if the four corners of the platform frame hit the building structure due to the offset of the device, it can also prevent the device from hitting the building structure and causing serious damage to the building structure and the device. After the collision, the device may swing. Through the provision of rollers, when the bottom of the device hits the building structure, the possibility of damage to the device or the building structure can be reduced. Before the device is fixed and installed, the swivel can be twisted to move the swivel upward, and then the lifting ring can be lifted upward to disengage the insertion rod from the circular hole at the upper end of the mounting frame. At this time, through the rotation connection between the mounting frame and the screw rod, the mounting frame can be rotated 90° so that the roller will not affect the installation and fixation of the device.
