Description

Technical Field

[0001] The present invention belongs to the technical field of elevator installation construction, and particularly relates to a device for automatically drilling an elevator shaft and its application. Background Art

[0002] As a vertical operation transportation device for personnel and goods, vertical lift elevators are widely used in high-rise buildings. Currently, the construction of elevator shafts is basically carried out by personnel, which is repetitive work according to floors. With the reduction of shaft construction personnel and the increase in average age in recent years, the industry's demand for shaft construction automation has been increasing, and at the same time, the situation of occupational diseases in shaft construction has also been examined. In particular, the repetitive and numerous drilling operations not only consume a large amount of time and physical strength of construction personnel, but the dust generated during the drilling process also greatly affects health. Therefore, the research on automated drilling technology for elevator installation is particularly important.

[0003] There is not much research on automatically drilling elevator shafts at home and abroad, and the actual application has just started. There is no mature product popularized in the market currently. For the solution of automatically drilling elevator shafts, most current research tends to use articulated robots. For example, in the patent "Elevator Intelligent Installation System" with the publication number CN209906138U, a six-axis articulated robot solution is provided. Cooperating with a construction lift platform, it can automatically complete the drilling operation. The technology of articulated robots is relatively mature, and suitable equipment can be selected for the field of elevator shaft drilling, greatly reducing the initial design difficulty. However, the whole machine of the articulated robot is very heavy and cannot be manually carried. It needs to be lifted by a crane to enter the site, and its application range is greatly limited; moreover, the articulated robot needs to detect and drill multiple walls, and it needs to constantly change tooling and adjust the pose, resulting in very low actual construction efficiency; more importantly, the extremely high cost of the articulated robot makes it impossible to be widely used in the field of elevator shaft construction currently.

[0004] In the patent "An Elevator Guide Rail Automatic Installation Equipment and Method" with the publication number CN113173471A, a solution different from that of articulated robots is proposed. In this solution, a set of drilling equipment is placed in each drilling area, and the drilling equipment only needs to perform drilling operations perpendicular to the shaft wall, greatly improving the construction efficiency; each set of drilling equipment can not only drill holes, but also theoretically perform the pre-installation work of guide rail brackets. However, since this solution cannot perform automatic translation in the horizontal or vertical direction and cannot adjust the drilling position, the position accuracy of drilling cannot be guaranteed; moreover, it is necessary to configure the same number of drilling machines as the drilling areas, and the position distance also needs to be consistent with the drilling spacing, and it cannot flexibly adapt to various shaft construction requirements. Summary of the Invention

[0016] S1. Install the equipment. Select the installation hole positions between the middle inner beam and the outer beam of the supporting wall according to the horizontal length of the elevator shaft and tighten them, so that the length of the main supporting wall beam is less than the horizontal length of the elevator shaft and there is an appropriate distance, to ensure that the equipment does not collide with the elevator shaft and there is a telescopic distance for the supporting wall. First, carry out the drilling work on the left and right shaft walls. The drilling module is installed vertically on the main supporting wall beam, making the drilling machine face the left and right shaft walls. The equipment installation work is completed. At this time, the lower support column is not locked and can slide vertically relative to the construction lift platform.

[0017] S2. Manually lift the construction lift platform to the reference position in the elevator shaft. After aligning the drilling machine vertically with the drilling reference position, lock the lower support column to fix its position relative to the construction lift platform. Align the sample line sensor vertically with the sample line by sliding the horizontal guiding part, and lock the sample line sensor. At this time, the calibration work for drilling the left and right shaft walls is completed.

[0018] S3. After the equipment automatically lifts and stops at the specified height, the telescopic drive beam extends to make the main wall support beam extend. The telescopic rolling elements abut against the left and right shaft walls and then automatically retract until the main wall support beam is tightly supported on the left and right shaft walls. The drilling module automatically completes the drilling operation, the telescopic drive beam retracts, and the equipment returns to the origin;

[0019] S4. Repeat step S3 until the drilling work on all the left and right shaft walls in the shaft is completed;

[0020] S5. Then, adjust the drilling pose of the rear shaft wall. Manually lift the construction lifting platform to the reference position in the elevator shaft, slide the lower support column and the components thereon towards the rear shaft wall until the fixed rolling element is at an appropriate distance from the rear shaft wall. Lock the lower support column to fix its position relative to the construction lifting platform. Install the drilling module parallel to the main wall support beam, make the drilling machine face the rear shaft wall and align it vertically with the drilling reference position. Align the wire sensor vertically with the wire by sliding the horizontal guiding part, and lock the wire sensor. At this time, the calibration work for drilling the rear shaft wall is completed;

[0021] S6. After the equipment automatically lifts and stops at the specified height, the vertical telescopic drive part automatically extends, driving the main wall support beam close to the rear shaft wall until the fixed rolling element abuts against the rear shaft wall. The telescopic drive beam automatically extends to make the main wall support beam extend. The telescopic rolling elements abut against the left and right shaft walls and then automatically retract until the main wall support beam is tightly supported on the left and right shaft walls. The drilling module automatically completes the drilling operation, the telescopic drive beam automatically retracts, and the vertical telescopic drive part automatically retracts, making the equipment return to the origin;

[0022] S7. Repeat step S6 until the drilling work on all the rear shaft walls in the shaft is completed.

[0023] As a further improvement of the above technical solution:

[0024] In step S3 and step S6, the automatic drilling operation of the drilling module includes the following steps:

[0025] S3-1. The horizontal sliding part automatically moves horizontally until the wire sensor detects the wire;

[0026] S3-2. The second-order drive part acts to make the steel bar detector approach the shaft wall until the second-order limit switch acts, that is, the steel bar detector is close to the shaft wall. The horizontal sliding part and the vertical sliding part act, and the steel bar detector can detect information such as the presence or absence and spacing of steel bars in the target area, and automatically select a suitable target position as the drilling point. The steel bar detector retracts;

[0027] S3-3. The horizontal sliding part and the vertical sliding part move automatically to align the drilling machine with the drilling point. The drilling machine starts to operate, and the first-order driving part acts to move the drilling machine towards the shaft wall to perform the drilling operation until the drilling depth switch acts, indicating that the drilling of the drilling machine is completed. Then, the first-order driving part retracts to move the drilling machine away from the shaft wall;

[0028] S3-4. Repeat step S3-3 until all the drilling work in this target area is completed.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] Through modular design, the present invention greatly reduces the requirements for on-site supporting equipment, is convenient for installation and assembly, and can adapt to most shaft construction requirements.

It automatically performs operations such as lifting and positioning, drilling positioning, steel bar detection, and drilling. By relatively reducing the moving time during the automatic operation process, while ensuring the drilling position accuracy, the construction efficiency is improved. Description of the Drawings
