Example 1

Referring to fig. 1-3, the present embodiment provides a high-stability attached lifting scaffold, including a frame body 1 disposed on one side of a wall 2, a first lifting assembly for driving the frame body 1 to move upward, and a second lifting assembly for driving the first lifting assembly to move upward, specifically, a plurality of fixing seats 3 vertically spaced are fixedly disposed on one side of the frame body 1 facing the wall 2, a vertical rod 9 vertically disposed is fixedly mounted at a tail end of the fixing seats 3, and a plurality of tooth plates 18 vertically disposed are mounted on a side wall of the vertical rod 9; the first lifting assembly comprises a supporting seat 10, an inner cavity 19 arranged in the supporting seat 10, a gear 21 arranged in the inner cavity 19 and meshed with the tooth piece 18, and a second motor 20 fixedly arranged on the outer side of the supporting seat 10 and used for driving the gear 21 to rotate, wherein one end of the supporting seat 10 is fixedly connected with the side wall of the wall body 2 through a mounting plate 11; the second lifting assembly comprises a first motor 4 fixedly mounted on the upper portion of the fixed seat 3 and a screw rod 5 connected to the output end of the first motor 4, a second connecting rod 16 is fixedly arranged at one end, away from the mounting plate 11, of the supporting seat 10, a sleeve 6 is fixedly arranged at the tail end of the second connecting rod 16, and the sleeve 6 is sleeved outside the screw rod 5 and is in threaded fit with the screw rod 5; the outer side of the supporting seat 10 is also provided with an anti-falling component acting on the longitudinal rod 9.

When the frame body 1 is used, the mounting plate 11 is fixed on one side of the wall body 2, and under the action of the anti-falling assembly, the frame body is fixed on one side of the wall body 2 by 1 time; when the support body 1 needs to be lifted upwards, the second motor 20 drives the gear 21 to rotate, the longitudinal rod 9 is driven to move upwards through the meshing action of the gear 21 and the tooth piece 18, the support body 1 is further driven to move upwards, after the support body 1 moves upwards for a certain distance, the first motor 4 drives the screw rod 5 to rotate, the screw rod 5 is matched with the sleeve 6 through threads, the sleeve 6 can be driven to move upwards, the support seat 10 is driven to move upwards through the second connecting rod 16, the second motor 20 and the gear 21 are driven to move upwards integrally, after the support seat 10 moves to a certain height, the mounting plate 11 and one side of the wall body 2 are fixed again, and therefore the support body 1 and the support seat 10 can move upwards alternately through the action of the first lifting assembly and the action of the second lifting assembly.

It is specific, prevent weighing down the subassembly and include fixed mounting and be in two sets of bases 14 that distribute about being in the supporting seat 10 outside, rotate and set up two sets of back shaft 12 between the base 14, fixed cover are located back shaft 12 outside fixed cover 13 and fixed mounting are in the gag lever post 15 of fixed cover 13 lateral wall, gag lever post 15 has the spacer pin (not shown) towards the terminal fixed mounting in one side of supporting seat 10, jack (not shown) that the spacer pin got into are seted up and can be supplied to the supporting seat 10 lateral wall, the articulated card 17 that are a plurality of vertical distributions that is provided with of vertical pole 9 lateral wall, the spacer pin passes the jack extends to between adjacent two sets of cards 17.

When the second motor 20 drives the gear 21 to rotate so as to drive the longitudinal rod 9 to move upwards, the limiting pin can sequentially cross the cards 17 positioned below, and when the longitudinal rod 9 stops rising, the limiting pin can abut against the bottoms of a certain group of cards 17 so as to support the longitudinal rod 9, so that the longitudinal rod 9 and the frame body 1 are prevented from falling downwards; when the supporting seat 10 needs to be lifted, the limiting rod 15 can be rotated to move the limiting pin out from between the two sets of the clamping pieces 17, at the moment, the first motor 4 drives the screw rod 5 to rotate so as to drive the supporting seat 10 to move upwards, and the situation that the supporting seat 10 cannot smoothly ascend due to the action of the limiting pin and the clamping pieces 17 in front can be avoided.

Furthermore, a second vertical groove 23 is formed in the side wall of the vertical rod 9, a first vertical groove 22 communicated with the second vertical groove 23 is formed in the vertical rod 9, the horizontal sectional area of the first vertical groove 22 is larger than that of the second vertical groove 23, and the clamping piece 17 is hinged to the inside of the first vertical groove 22.

Furthermore, the area of the clamping piece 17 is the same as the horizontal sectional area of the inner cavity of the first vertical groove 22, one end of the clamping piece 17 is hinged with one side of the first vertical groove 22 far away from the second vertical groove 23, and the clamping piece 17 inclines downwards towards one end of the second vertical groove 23.

When the vertical rod 9 moves upwards, the limiting rod acts on the card 17 below and drives the adaptive rotation of the card 17 in the west, in the use process of the frame body 1, the limiting rod is abutted to the bottom of the card 17, and one end of the card 17 is in an inclined state and props against the inner wall of the first vertical groove 22, so that the anti-falling function is realized.

In this embodiment, the mounting plate 11 is fixedly connected to the sidewall of the wall 2 through a fastening bolt.

In this embodiment, the guide rail 8 of vertical distribution is installed to 1 one side of support body, 6 lateral walls of sleeve are still fixed and are provided with first connecting rod 7, first connecting rod 7 end seted up with the draw-in groove (not shown) of 8 looks adaptations of guide rail.

When the first motor 4 drives the screw rod 5 to rotate so as to drive the supporting seat 10 to move upwards, the supporting seat 10 can be ensured to stably move upwards through the matching of the clamping groove and the guide rail 8.

Example 2

Referring to fig. 1, in this embodiment, compared with embodiment 1, one end of the screw rod 5 far from the first motor 4 is rotatably connected to the bottom of the corresponding fixing base 3.
