As the maintenance equipment of some major places, the lifting column is widely used in scenic spots, pedestrian streets, enterprises, highways, airports and other places. How does the lifting column prevent derailment? The following lifting column manufacturer Qi Xinlong to introduce to you.
The lifting column anti-derailment device includes a mounting plate and a sensor, a mounting plate installed on the cage or the driving device, a sensor on the mounting card, and a sensor end on the metal part of the lifting column. The mounting plate and the sensor are arranged on the top of the cage or the transmission device. The mounting plate and the sensor are arranged at the bottom of the column well, and the output lines of the two sensors are connected to the control device. Proximity switch.
1, lifting column bottom frame installation leveling, self-lifting platform in place, so that the center line coincides with the center line of the column .. Install pull rod on the self-lifting platform, wear wire rope, install the first group of columns, put the standard joint into the sleeve and connect with the foundation bolt .. The adjusted net distance of the column track surface shall be controlled within 1985mm, and the vertical deviation shall be ≤ 1.5 ‰.
2. Place the lifting pulley on the top of the two pillars installed and wear the hoist wire rope. Use the electric hoist to lift the jack-up platform. Retract the telescopic card to the clamping position until the bottom of the telescopic card is flush with the first grid on the top of the column. Reset the telescopic card plate, loosen the lifting wire rope, remove the lifting pulley and place it on the platform. Use the handle to install the second group of standard joints. Before tightening the bolts, ensure that the first group and the second group are on the same vertical line, and the deviation at the joint is less than 0.5mm. Then place, and wear lifting wire rope installation, and fix the pressure beam.
3. The lifting column shall be installed with reinforced diagonal braces, and the connecting bolts of the above parts shall be fastened. The verticality deviation of the installed standard section shall be checked, whether the adjustment meets the requirements and whether the weight connection is reliable.
4. The lifting column is then put into the hanging basket, around the wire rope, and the linkage safety device is installed. At this time, the lifting column is basically installed .. Continue to increase to the gantry frame with the specified height for the first time, and install a good parking bracket at the corresponding height, Then it can be put into trial operation. When the erection height of the door frame rises to 6m, the first attachment shall be set and increased every 3m thereafter.
