The utility model can move universally and hangs, comprises beam 1, support 2, three main parts of base 3 and is made up of, and can be fixed by screw at the junction of three parts. On the top of the row suspension, the crossbeam 1 is connected with the support 2 with the upper inclined support 4, and screws can be installed at the joint to fix it. At the bottom of the row crane, the base 3 is connected to the support 2 with the lower inclined support 5, and screws can be installed at the connection. Four universal wheels 6 are installed on the hanging base 3, and are fixed on the bottom of the base 3 by screw mounting screws, caster brakes 7 are installed on the universal wheels 6, and the advance and stop of the hanging are controlled with the caster brakes 7. Using the principle of triangular stability, install a pair of universal wheels with disc brakes on the diagonal of the quadrilateral formed by the base, and install ordinary universal wheels on the other diagonal, which not only ensures the control of the traveling process of the crane, but also reduces the The production cost of the hanging crane is reduced. When the crane is moving, release the brake, and when it is necessary to stop the crane, start the brake, and the crane can stop without swinging. Hanging ring 8 is installed on the row hanging beam 1, and when in use, the screen cabinet can be lifted and lowered by hanging the chain hoist on the ring 8.

The installation method of the screen cabinet can be installed by the universal mobile crane as follows: put the steel wire rope on the four corners of the top of the screen cabinet, hang the steel wire rope on the upside-down chain, hang the upside-down chain on the ring 8 on the horizontal beam 1, and pull the Reverse the chain to lift the screen cabinet. After the screen cabinet is hoisted by the crane, the staff pushes the crane bracket 2 to realize the movement of the screen cabinet. After reaching the designated position, step on the caster brake 7 to fix the crane. Pull the reverse chain to slowly lower the screen cabinet and adjust it. After marking the drilling position of the anchor screws, it is no longer necessary to remove the screen cabinet, and the screen cabinet can be directly hoisted by a crane to perform drilling and tapping work. After completion, the screen cabinet is placed again and adjusted to complete the work. After the improvement, the working time is greatly shortened, the required staff is greatly reduced, and the work efficiency is greatly improved.

The main structure of the mobile crane can be made of channel steel, which is strong and durable, and the joints are all connected by screws, which is easy to disassemble.

Due to the large mass of the screen cabinet, the supporting function of the upper inclined support 4 is very important. Therefore, it is necessary to facilitate the disassembly of the upper inclined support 4 and ensure that the upper inclined support 4 will not be accidentally separated from the beam 1. The following scheme is designed: as shown in the figure 3 and 4, the crossbeam 1 and the upper oblique support 4 can be connected by bolts 9 and nuts 10. Positioning holes 12 are provided on the bolts 9 . Lock body 24 is installed on the upper oblique branch 4.

A baffle groove 18 is horizontally defined in the lock body 24 , and the baffle groove 18 communicates with the first guide groove 19 and the second guide groove 20 respectively. The pin 22 is installed in the first guide groove 19, and the push rod 11 is installed on the bottom of the pin 22. The diameter of the push rod 11 is smaller than that of the pin 22 . A positioning ring 25 is installed in the lower port of the first guide groove 19 . The positioning ring 25 cooperates with the push rod 11 to limit the position of the push rod 11 . A first spring 13 is installed on the outer periphery of the push rod 11 , one end of the first spring 13 is in contact with the positioning ring 25 , and the other end of the first spring 13 is in contact with the pin 22 . Slide block 21 is installed in the second guide groove 20, and limit ring 23 is installed at the second guide groove 20 lower ports, and limit ring 23 is the limit of slide block 21, prevents slide block 21 from falling in the second guide groove 20. The second spring 17 and the baffle 15 are installed in the baffle groove 18 . A second spring 17 is installed at one end of the baffle 15 , and a through hole 14 is horizontally opened at the other end of the baffle 15 . After the baffle plate 15 compresses the second spring 17 and moves, the through hole 14 can cooperate with the first guide groove 19 . The pin 22 is in contact with the baffle 15 . A triangular protrusion 16 is installed in the second guide groove 20 , and the triangular protrusion 16 is connected with the baffle plate 15 . A top block 26 is arranged on the slider 21 , and the top block 26 cooperates with the triangular protrusion 16 . The push rod 11 cooperates with the positioning hole 12 . For preventing nut 10 from falling off on bolt 9, lock body 24 is installed on the upper oblique support 4. When the nut 10 needs to be locked, the pin 22 is pushed down through the first guide groove 19, so that the pin 22 drives the push rod 11 and is inserted into the positioning hole 12, and the pin 22 is separated from the through hole 14; Driven by the second spring 17, it moves to the left. The through hole 14 and the first guide groove 19 are staggered, the baffle plate 15 positions the pin 22 and the push rod 11 , and the push rod 11 cannot be pulled out from the positioning hole 12 . When unlocking is required, when the nut 10 is removed from the bolt 9, the slider 21 is pushed upwards, and the slider 21 pushes the triangular projection 16 to move to the right through the top block 26, and the triangular projection 16 drives the baffle plate 15 to move to the right. When the hole 14 is aligned with the first guide groove 19, the pin 22 is inserted into the through hole 14 driven by the first spring 13. At this time, the push rod 11 is separated from the positioning hole 12 and unlocked, and the bolt 9 can be moved from the crossbeam 1 to the upper. Remove the oblique support 4. The free ends of the pin 22 and the top block 26 are all hemispherical, which can prevent the pin 22 and the top block 26 from being stuck during the action and affect the normal operation.
