Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
Referring to fig. 1 to 13, the lifting scaffold of a preferred embodiment of the present invention comprises a lifting scaffold, which comprises a plurality of sets of supporting frames 1 distributed along a horizontal direction, a plurality of sets of supporting plate assemblies 2 distributed along a vertical direction, and a horizontal truss 3 located at the bottom of the supporting frames, wherein each set of supporting frames comprises a front supporting rod 4 and a rear supporting rod 5 arranged in parallel, the bottom ends of the front supporting rod and the rear supporting rod are fixedly connected through a connecting rod 6, each set of supporting plate assemblies comprises a plurality of scaffold boards 7 connected in sequence, each set of supporting plate assemblies further comprises a plurality of triangular supports 8 and Z-shaped supports 9 located below the scaffold boards, each triangular support comprises a front supporting rod 10 fixedly connected with the front supporting rod, the rear support rod 11 is connected with the rear support rod, the transverse support rod 12 is connected with the top end of the front support rod at one end and connected with the top end of the rear support rod at the other end, the first inclined support rod 13 is connected with the front support rod at one end and connected with the bottom end of the rear support rod at the other end, and the length of the front support rod is smaller than that of the rear support rod;
the Z-shaped support comprises a square frame 14 fixedly connected with the front support rod and the rear support rod and a second inclined support rod 15 fixedly connected with the square frame, and a guide rail 16 is arranged on the rear support rod connected with the Z-shaped support;
the horizontal truss comprises a plurality of sequentially connected Z-shaped supports 17, each Z-shaped support comprises a rectangular frame 18 fixedly connected with the front support rod or the rear support rod, a connecting vertical rod 19 fixedly arranged in the middle of the rectangular frame, and two third inclined support rods 20, one ends of the third inclined support rods are connected with the top ends of the connecting vertical rods, and the other ends of the third inclined support rods are fixedly connected with the rectangular frame.
Wherein, the back support rod connected with the Z-shaped support is provided with a guide rail to improve the connection strength between the front support rod and the back support rod. And the guide rail is used for being connected with a guide seat 21 on a building wall body so as to improve the lifting stability of the lifting scaffold. When the crane works, the connecting hook at the end part of the crane is connected with the support frame, and when the crane needs to ascend, the crane drives the connecting hook to ascend so as to drive the support frame connected with the crane to ascend until the support frame moves to a preset position. In the lifting process, the guide rail moves in the guide seat on the wall body, so that the guide function is realized.
Besides the guiding function, the guiding seat also has the anti-falling function, and comprises a seat body 22 and an anti-falling device 23, wherein the seat body comprises a connecting shell 24 and a support arm 25 arranged at the front end of the connecting shell, a guiding hole 26 is arranged in the support arm, a connecting rod avoiding hole 27 is arranged on the side wall of the guiding hole, and the connecting rod avoiding hole is used for avoiding a connecting rod 28 on a guide rail so as to enable the connecting rod to lift. The falling protector comprises a connecting pin shaft 30 which is horizontally arranged and the end part of which is rotatably arranged on the support arm, a falling prevention block 31 the bottom of which is fixedly connected with the connecting pin is arranged above the connecting pin, a trigger block 32 the rear end of which is fixedly connected with the connecting pin is arranged in front of the connecting pin, a balancing weight 33 the top end of which is fixedly connected with the connecting pin is arranged below the connecting pin, and a falling prevention block avoiding hole 34 and a balancing weight avoiding hole 35 below the falling prevention block avoiding hole are arranged on the front side wall of the connecting shell. Under the normal state, the falling protector is slightly inclined forwards as a whole under the action of gravity. When the scaffold is lifted, the connecting rod pushes the end part of the trigger block upwards to drive the falling protector to integrally rotate until the falling prevention block is transferred into the falling prevention block avoiding hole. After the connecting rod moves past the trigger block, the falling protector returns to the original position to wait for the next connecting rod to push the falling protector to rotate. The scaffold descends rapidly, the impact force generated by the connecting rod to the trigger block is large, the falling protector rotates to the rear end of the balancing weight rapidly and contacts with the top wall of the balancing weight, and at the moment, the surface of the falling protector is in a horizontal position. Because the descending speed is high, after the connecting rod moves over the trigger block, the falling protector is not in the original position, the next connecting rod descends to the upper part of the falling prevention block until the falling prevention block contacts with the falling prevention block, and at the moment, because the rear end of the balancing weight is tightly propped against the top wall of the avoiding hole of the balancing weight, the connecting rod cannot descend continuously, so that the guide rail and the scaffold are prevented from descending continuously. Compared with the existing split type falling protector, the falling protector of the guide seat has the advantages of simpler structure, higher strength and more reliable falling prevention performance.
In this embodiment, the below of every group fagging subassembly is provided with two Z characters respectively and props, and the left and right sides that every Z character propped still is provided with a triangle respectively and props.
In this embodiment, the number of the supporting frames is five.
In this embodiment, the height of the front support rod is higher than that of the rear support rod, and a fourth inclined support rod 36 is further disposed between the top end of the front support rod and the top end of the rear support rod.
In this embodiment, the support frame is further provided with a plurality of baffles connected with the front support rod.
In this embodiment, lifting scaffold still includes two sets of lifting hook coupling assembling, and every lifting hook coupling assembling of group includes the last lifting hook connecting piece 37 that links firmly with the back bracing piece, is located lifting hook connecting piece below and the lower lifting hook connecting piece 38 of being connected with the horizontal truss.
The lifting hook connecting assembly is arranged to be connected with the output end of the lifting equipment. When the lifting hook works, the two connecting hooks at the output end of the lifting equipment are respectively connected with the upper lifting hook connecting piece and the lower lifting hook connecting piece. The upper lifting hook connecting piece and the lower lifting hook connecting piece are connected with the supporting frame through the connecting frame.
