Detailed ways

A kind of scaffold fastener nut removal machine as shown in Figure 1, comprises frame 5, sleeve 7, sleeve driving device and clamping device; The slide plate 3 and the pillar 1 fixedly installed on the top of the slide plate 3 and the vertical groove located at the top of the pillar 1; The drive motor 9; the sleeve 7 is fixedly mounted on the output end of the gearbox 8, and is opposite to the vertical groove at the top of the pillar 1; the preferred structure of the utility model is suitable for dismounting the cross-shaped scaffold fastener, because ten The bolts of zigzag scaffolding fasteners are "T" shaped, and they are all standard parts. When setting the vertical groove at the top of the pillar, it should be ensured that its width is the same as the diameter of the bolt, or its width is slightly larger than the diameter of the bolt. The utility model can also adapt to the tail shape of different scaffold fastener bolts by changing the shape of the vertical groove at the top of the pillar. It is suitable for the disassembly of various scaffold fastener nuts, and can also be used to disassemble the nut of a single bolt to improve the use efficiency of the equipment. .

The sliding device includes two cylindrical slide rails 4 fixedly installed on the top of the frame 5 and two sliding sleeves and a slide plate driving mechanism fixedly installed on the bottom of the slide plate 3 respectively matched with the cylindrical slide rails 4; The installation direction of the slide rail 4 is the same as the installation direction of the sleeve 7. The cylindrical slide rail has two functions, one is to ensure the movement direction of the slide plate, and the other is to support the slide plate. Other forms of sliding devices can also be used; in order to ensure that the dismounted nuts do not fall directly during the disassembly process, a tray 6 for accommodating the dismounted nuts is also provided under the slide plate.

Described gearbox 8 is a worm gear gearbox, and described driving motor 9 is fixedly installed on frame 5 bottom, and its output end is positioned at frame 5 side, and the output end of described driving motor 9 and the input end of gearbox 8 A belt transmission mechanism is set between them, and the gearbox can also adopt other forms, such as a spur gear gearbox, but in the actual installation process, the relative positional relationship between the drive motor and the gearbox should be adjusted according to different types of gearboxes.

Described frame 5 bottoms are also provided with road wheels 10, and the effect of road wheels is to facilitate the complete machine to move the position, also can not be provided with road wheels, directly complete machine is fixed on the foundation.

Described slide plate drive mechanism comprises the rack that is fixedly installed on the bottom surface of slide plate 3, the gear that is installed on frame 5 and the gear that meshes with rack and is installed on the rotating handle 2 on the gear shaft; The length direction of described rack and slide plate 3 motion The direction is the same; the rack and pinion cooperate with each other, and the slide plate can be driven to slide during the process of turning the handle. During the disassembly process of the nut, it is convenient to adjust the position of the slide plate according to the length of the stripped wire. The screw drive is used to push the slide plate to move backward. When there is a bolt that cannot be dismantled by this device or it is stuck, pull the handle to drive the slide plate to move backward, so as to disengage the bolt and nut.

In the specific application process, first of all, the tail of the scaffold fastener bolt is clamped into the vertical groove at the top of the pillar. Of course, the cross-sectional shape of the vertical groove can be designed as a section shape of an excellent arc or a rectangle, and the upper end is open. When installing, the bolt Insert the tail into the vertical groove, then pull the handle to drive the slide plate to move towards the sleeve, insert the nut into the inner hexagonal hole at the end of the sleeve, and then start the driving motor to take off the wire. In the groove, the sleeve drives the nut to rotate, and the handle must be released when the wire is removed, because the wire removal itself is a thread driving mechanism, and the slide plate will move backward under the drive of the wire removal driving mechanism during the wire removal process, and the wire removal After the completion, take off the scaffold fastener and take out the nut in the sleeve. Using the scaffold fastener nut removal machine disclosed by the utility model can greatly improve the maintenance efficiency of the scaffold fastener, and the driving force generated by the driving motor The torque is much greater than the torque that can be generated by manual wrench, and some nuts of scaffold fasteners that cannot be disassembled manually can be disassembled, which greatly reduces the replacement cost in the maintenance process and can also prolong the service life of scaffold fasteners.
