Problems solved by technology
[0009] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an automatic leveling control method for construction elevators. Combining the characteristics of handle operation and automatic leveling operation, it solves the problem of repeated leveling by manual operation of the hanging cage and low efficiency. Traditional automatic leveling is right Inconsistent with the field use, the encoder pulse fault cannot be detected immediately and the floor calibration is frequent and other technical problems

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035] This embodiment provides an automatic leveling control method for a construction elevator, such as figure 1 shown, including the following steps.
[0036] Step 1, the cage of the manually operated elevator runs at a high-speed gear and approaches the target floor.
[0037] Step 2, when the distance between the cage and the target floor △h<2 meters, manually operate the elevator to make the cage run at a medium-speed gear, and continue to approach the target floor.
[0038] Step 3: When the distance △h<0.5m between the hoisting cage and the target floor, the control system sends out a voice prompt to enter the automatic leveling area, the manual operation ends, and the automatic leveling operation starts.
[0039] Step 4, control the elevator to make the cage run at low speed to complete the automatic leveling.
[0040] Further, the station def...

The invention belongs to the technical field of engineering machines and particularly discloses an automatic leveling control method of a construction lifter. The automatic leveling method of the construction lifter comprises the following steps that 1, a lifting cage of the lifter is manually operated and operates at a high-speed gear to get close to a target floor; 2, when the distance delta h between the lifting cage and the target floor is smaller than 2 meters, the lifter is manually operated to make the lifting cage operate at a middle-speed gear to continue getting close to the target floor; 3, when the distance delta h between the lifting cage and the target floor is smaller than 0.5 meter, a control system sends out a voice prompt that the lifting cage enters an automatic leveling area, manual operation is ended, and automatic leveling operation is started; and 4, the lifter is controlled to make the lifting cage to operate at a low speed, and automatic leveling is completed. The automatic leveling method of the construction liftercan achieve automatic leveling control for the lifter, thereby improving the building construction efficiency; in the operation process, the pulse value of an encoder is verified in real time so that operation stability and reliability can be ensured; and floors are calibrated automatically without human intervention, and operation is easy.
Description
technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to an automatic leveling control method of a construction hoist. Background technique [0002] As the most commonly used material transportation equipment in the construction process, the construction hoist still uses a simple up and down operation mode of the handle in the actual use of most construction sites. The handle operation method is simple, and the operation is stable and reliable. However, the driver needs to keep an eye on the operation of the cage during the operation. In order to facilitate the entry and exit of cargo carts, it is necessary to control the floor of the cage and the level difference of the landing. The driver needs to adjust the position of the lift back and forth for leveling. On the other hand, the handle operation method is labor-intensive and inefficient. In order to reduce the driver's operating intensity, some manufacturers have be...
