DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

During specific implementation: as shown in Figures 1-6, a safety frame for use at a construction site of a building project includes a safety frame body 1, a first support column 2, a second support column 3 and a support base 4: two groups of first support columns 2 are symmetrically arranged on the bottom outer wall of the safety frame body 1, the first support column 2 is located above the second support column 3, and a support base 4 is arranged on the bottom outer wall of the second support column 3, a lifting and lowering adjustment mechanism is arranged inside the support base 4, an auxiliary moving mechanism is arranged below the lifting and lowering adjustment mechanism, and a locking stabilization mechanism is arranged on the side of the auxiliary moving mechanism.

The lifting and lowering adjustment mechanism includes a limit support frame 5, a driving motor 6 and a supporting shaft 7. The top outer wall of the supporting base 4 is provided with a limit support frame 5, and the limit support frame 5 is arranged in a "Z" shape. The top outer wall of the limit support frame 5 is provided with a driving motor 6, and the driving motor 6 is connected to the top outer wall of the supporting shaft 7. The bottom outer wall of the supporting shaft 7 is connected to the top outer wall of the driving gear 8. The side of the driving gear 8 is meshed with a driven gear 9. The interior of the supporting base 4 is arranged as a cavity structure. The driving gear 8 and the driven gear 9 are both rotatably installed with the bottom inner wall of the supporting base 4. A reciprocating screw rod 10 is rotatably installed on the top outer wall of the driven gear 9. A sliding member 11 is arranged on the outside of the reciprocating screw rod 10. The sliding member 11 is slidably connected to the side inner wall of the second supporting column 3, and the top outer wall of the sliding member 11 is connected to the bottom outer wall of the first supporting column 2. The first supporting column 2 is arranged as a cavity structure; when it is needed To adjust the overall support height of the safety frame, you first need to turn on the drive motor 6. When the drive motor 6 is turned on, it will automatically drive the support shaft 7 to rotate and then drive the drive gear 8 to rotate. Then, the drive gear 8 rotates and automatically drives the driven gear 9 to rotate and then drives the reciprocating screw 10 to rotate. When the reciprocating screw 10 rotates, it will automatically drive the sliding member 11 to move inside the second support column 3. At this time, since the sliding member 11 is slidably installed with the inner wall of the second support column 3, when the reciprocating screw 10 rotates, it will only drive the sliding member 11 to realize the vertical sliding trajectory movement. Then, the movement of the sliding member 11 will automatically drive the first support column 2 to move and then drive the safety frame body 1 to lift the height. When the safety frame body 1 is adjusted to a suitable height, the drive motor 6 can be turned off at this time. It is noted here that the drive motor 6 has a self-locking function. After being turned off, the safety frame body 1 can still maintain the unchanged position after moving.

The auxiliary movement mechanism includes a limit mounting plate 12, a limit shaft 13 and a running wheel 14. The limit mounting plate 12 is symmetrically arranged on the outer wall of the bottom end of the support base 4. The limit shaft 13 is rotatably installed between the two limit mounting plates 12, and the outside of the limit shaft 13 is provided with a running wheel 14; when it is necessary to adjust the support position of the safety frame, it is only necessary to push the safety frame, and the running wheel 14 here plays the role of auxiliary movement. The setting of the limit mounting plate 12 and the limit shaft 13 plays the role of auxiliary support for the running wheel 14

The locking stabilization mechanism includes a positioning mounting plate 15 and a cavity column 16. The side outer wall of the limiting mounting plate 12 is provided with a positioning mounting plate 15, and the top outer wall of the positioning mounting plate 15 is connected to the bottom outer wall of the supporting base 4. The cavity column 16 is rotatably installed between the two positioning mounting plates 15, and a clamping plate 17 is arranged on the outside of the cavity column 16. A threaded groove is provided inside one of the positioning mounting plates 15, and a threaded groove is provided through the side outer wall of the other positioning mounting plate 15, and the threaded groove and the limiting bolt 18 are threadedly connected; when the safety frame needs to be locked and positioned after being moved to a suitable position, the limiting bolt 18 needs to be screwed out from the inside of the threaded groove, and then the clamping plate 17 is rotated until it is in contact with the walking wheel 14 and engaged with it. After adjustment, the limiting bolt 18 is passed through one of the positioning mounting plates 15 and screwed into the threaded groove of the other positioning mounting plate 15.

When the utility model is in use, when it is necessary to adjust the overall supporting height of the safety frame, it is necessary to first turn on the driving motor 6. When the driving motor 6 is turned on, it will automatically drive the supporting shaft 7 to rotate and then drive the driving gear 8 to rotate. Subsequently, the driving gear 8 will automatically drive the driven gear 9 to rotate and then drive the reciprocating screw rod 10 to rotate. When the reciprocating screw rod 10 rotates, it will automatically drive the sliding member 11 to move inside the second supporting column 3. At this time, since the sliding member 11 is slidably installed with the inner wall of the second supporting column 3, when the reciprocating screw rod 10 rotates, it will only drive the sliding member 11 to realize the sliding trajectory movement in the vertical direction. Subsequently, the movement of the sliding member 11 will automatically drive the first supporting column 2 to move and then drive the safety frame body 1 to lift the height. When the safety frame body 1 is adjusted to When the height is appropriate, the drive motor 6 can be turned off. It is noted here that the drive motor 6 has a self-locking function. After being turned off, the safety frame body 1 can still maintain the position after moving. When the supporting position of the safety frame needs to be adjusted, it is only necessary to push the safety frame. Here, the walking wheel 14 plays an auxiliary movement effect, and the setting of the limit mounting plate 12 and the limit shaft 13 plays an auxiliary support effect on the walking wheel 14. When the safety frame moves to the appropriate position and needs to be locked and positioned, it is first necessary to unscrew the limit bolt 18 from the inside of the threaded groove, and then rotate the locking plate 17 until it contacts and engages with the walking wheel 14. After adjustment, the limit bolt 18 is passed through one of the positioning mounting plates 15 and screwed to the inside of the threaded groove of the other positioning mounting plate 15.

In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
