Description

Technical Field

[0001] The present invention belongs to the technical field of lifting large equipment or components using a shoulder pole beam, and particularly relates to a horizontal state monitoring device for lifting a shoulder pole beam. When lifting using a shoulder pole beam, the lifting speed of the lifting equipment is inconsistent and the shoulder pole beam is tilted. It is suitable for monitoring the horizontal state of the shoulder pole beam when large equipment or components are lifted using a shoulder pole beam. Background Art

[0002] With the development and progress of society, as well as the vigorous development of domestic cranes and the improvement of transportation equipment, the degree of factory manufacturing and assembly of equipment is getting higher and higher. Therefore, the requirements for the lifting of equipment after it arrives at the site are more stringent. When large equipment or components are lifted at the construction site, due to the heavy weight of the equipment, the shape of the components or the particularity of the installation position, it is often necessary to use a shoulder beam to lift them into place. Since lifting with a shoulder beam often requires the cooperation of multiple lifting equipment, the level of the shoulder beam is directly related to whether the equipment can be installed safely, efficiently and accurately.

[0003] In view of the above technical background, a horizontality monitoring device and monitoring method for the lifting of a shoulder pole beam are specially invented to meet the requirements of real-time monitoring of the horizontal state of the shoulder pole beam during the entire lifting process, ensuring the safe and efficient completion of the entire operation process. The device uses the vertical downward effect of gravity in a natural state to ensure that the laser emitted by the laser pen is always in a horizontal state, and the horizontal state of the shoulder pole beam is observed in real time by the angle between the emitted horizontal laser and the upper flange plate of the shoulder pole beam. The deviation is accurately calculated by observing the scale line on the target plate, so that the signal commander and the crane driver can make adjustments at any time to ensure that the shoulder pole beam is always in a horizontal state, ensuring safe and efficient construction. Summary of the invention

[0004] The purpose of the present invention is to provide a device for monitoring the horizontal state of a shoulder pole beam during installation, which solves the problems that when the shoulder pole beam is used for lifting, the horizontal state of the shoulder pole beam is difficult to observe visually as the lifting height increases and the distance becomes farther, and it is difficult to observe when the deviation is small. The device has the function of providing a horizontal reference and amplifying the deviation, which provides a safe and reliable guarantee for the smooth progress of installation and construction, and can also save construction time and reduce costs.

[0005] The present invention comprises a magnetic meter base 1, a fixed lock nut 2, a balance bar 3, a mounting base 4, a locking bolt 5, an adjustment base 6, an adjustment screw 7, a laser pen 8, a snap screw 9, a snap 10, a target plate 11, and a fastening bolt 12. The laser pen 8 is mounted on the adjustment base 6 through the snap screw 9 and the snap 10, and then the adjustment base 6 is mounted on the mounting base 4, and the adjustment base 6 is adjusted through the adjustment screw 7. After the adjustment is completed, the adjustment base 6 is fastened and locked to the mounting base 4 through the locking bolt 5, and the adjustment screw 7 is locked at the same time. Then, the entire mounting base 4 is mounted on the balance bar 3, fixed by the fixed lock nut 2, and at the same time, it is ensured that the entire mounting base 4 can rotate freely around the balance bar 3 without a block group. Finally, the balance bar 3 is tightened on the magnetic meter base 1, and the assembly of the entire device can be completed. During installation, the entire device is adsorbed on one side of the flange plate on the shoulder beam through the magnetic meter base, and the target plate 11 is fixed on the other side of the shoulder beam through the fastening bolt 12, so that the laser emitted by the laser pen 8 hits the target plate.

[0006] The innovative features of the present invention are as follows:

[0007] First, the device and monitoring method can quickly adjust the weight load distribution of the lifting equipment during lifting through intuitive changes in deviation, thereby avoiding lifting safety accidents caused by equipment overload.

[0008] Second, the device and monitoring method have the function of conveniently observing deviations: if the installation distance between the target plate and the laser emitting part is 10m, when the shoulder beam deviates by 1°, the tangent function can be used to calculate that the light spot on the target plate is offset by about 17.5mm. In this way, the 1° deviation is amplified and converted into 17.5mm. As the length of the shoulder beam increases, the installation distance between the target plate and the laser emitting part increases accordingly, and the effect will be more obvious.

[0009] Third, the device and monitoring method have the function of monitoring deviation in multiple ways. In addition to observing the scale of the target plate, the horizontal state of the shoulder beam can be monitored by observing the laser beam emitted by the laser pen which is always horizontal and observing the change in parallelism between the beam and the flange plate of the shoulder beam. Since the horizontal beam provides a reference object that is always horizontal, the ease of observation is greatly improved.

[0010] Research idea of ​​the present invention

[0011] Mounting base 4 development:

[0012] The mounting base 4 is connected to the balance bar 3 and the adjustment base 6, and is a stationary and rotating connection part. First, according to the diameter of the balance bar 3, the drilling diameter is selected to ensure that the mounting base 4 can rotate by itself without a card group, and the gap cannot be too large. Secondly, the inverted triangle structure is selected to ensure that the center of gravity of the entire device is at the bottom, so that the torque under the action of gravity is larger and more sensitive. Finally, the hole connected to the locking screw 5 is opened as a long hole, which can meet the adjustment amount of the adjustment base 6. The entire mounting base 4 is made of a 2mm thick steel plate with a bent hole.

[0013] Development of adjustment base 6:

[0014] First, the buckle 10 is made according to the outer dimensions of the laser pen 8, and then the adjustment base 6 is designed according to the installation base 4; secondly, the adjustment base 6 is made by bending and opening a 2mm thick steel plate. After the production is completed, the center of gravity is basically at the installation position of the laser pen.

[0015] The advantages of the present invention are that the device and the monitoring method have the functions of providing a horizontal reference and converting and amplifying deviations, and can convert angle deviations that are difficult to observe into linear height changes that are easy to observe. In addition, the device has a simple structure, is easy to manufacture, easy to install, and easy to operate; the development cost is low, the production cycle is short, and it can be reused many times.
