As shown in fig. 1 and 2, the second moving assembly 400 includes a second driving element 410 fixedly disposed on the first moving element 320 by welding, riveting, screwing, and the like, and a second moving element 420 in transmission connection with the second driving element 410, wherein the second moving element 420 can reciprocate along a horizontal direction. In this way, the first driving member 310 drives the first moving member 320 to reciprocate along the length direction of the supporting member 200, so as to drive the second moving assembly 400 to integrally reciprocate along the length direction of the supporting member 200, and further drive the lattice column to reciprocate along the length direction of the supporting member 200; and, through second driving piece 410 drive second moving member 420 along horizontal direction reciprocating motion to can drive lattice column along horizontal direction reciprocating motion, and then combine first driving piece 310, first moving member 320, second driving piece 410 and the mutual synergistic effect of second moving member 420, can hang up lattice column along vertical direction and move along the horizontal direction, make the arrival appointed place that lattice column can be nimble, the construction of being convenient for, the efficiency of construction is high.

It should be noted that the supporting member 200 may be in the form of a supporting frame, a supporting column or a supporting bar, and it is only necessary to provide support and installation for the first moving assembly 300 and the second moving assembly 400. The first driving member 310 and the supporting member 200 are preferably spaced apart from each other so as to avoid interference of the supporting member 200 with the movement of the first moving member 320, for example, the first driving member 310 and the supporting member 200 may be connected by a connecting rod or a connecting block so that the first driving member 310 and the supporting member 200 are spaced apart from each other. The hoisting object of the hoisting device 10 is not limited to hoisting the lattice column, and can hoist other members or articles, and only the hoisting requirements are met.

The first driving member 310 drives the first moving member 320 to reciprocate along the length direction of the supporting member 200, and the reciprocating motion can be realized in a telescopic manner (for example, a telescopic rod of a hydraulic cylinder or a pneumatic cylinder drives the first moving member 320 to reciprocate along the vertical direction), or in a rotating manner (for example, a screw-nut structure drives the first moving member 320 to reciprocate along the vertical direction), and only the requirement that the reciprocating motion along the length direction of the supporting member 200 can be driven by the first moving member 320 is satisfied.

As shown in fig. 1, in the embodiment, the first driving member 310 includes a rotating motor (not labeled) and a screw rod 330 connected to a rotation output end of the rotating motor. The first moving member 320 is sleeved on the screw rod 330 and is in threaded fit with the screw rod 330, and one end of the first moving member 320 is in guiding fit with the supporting member 200. So, when the rotation output end of the rotating electrical machine rotates, the lead screw 330 can be driven to synchronously rotate, the lead screw 330 is in threaded fit with the first moving member 320, and the guide fit between the supporting member 200 and the first moving member 320 is combined, so that the first moving member 320 reciprocates along the length direction (shown as the direction a in fig. 1) of the lead screw 330, and further the second moving assembly 400 arranged on the first moving member 320 reciprocates along the length direction of the lead screw 330, thereby driving the lattice column to reciprocate along the length direction of the lead screw 330. The first moving member 320 may be a moving plate, a moving block, or a moving bar. The thread fit of the first moving member 320 is that the corresponding connecting through hole is formed in the first moving member 320, the thread fit can be achieved by forming an internal thread matched with the thread of the screw rod 330 on the inner wall of the connecting through hole (not marked), a sleeve (not marked) provided with an internal thread can be fixedly arranged in the connecting through hole, and the thread fit with the screw rod 330 is indirectly achieved by utilizing the thread fit of the sleeve and the screw rod 330.

The slide rail 210 may be fixed on the supporting member 200 by riveting, screwing, or the like.

The second driving element 410 drives the second moving element 420 to reciprocate along the horizontal direction, and the reciprocating motion can be realized in a telescopic mode (for example, a telescopic rod of a hydraulic cylinder or a pneumatic cylinder drives the second moving element 420 to reciprocate along the horizontal direction), and the reciprocating motion can also be realized in a linear motor driving mode only by meeting the requirement that the second moving element 420 can be driven to reciprocate along the horizontal direction.

Wherein, the movable block can realize stable, reliable connection through modes such as spiro union, welding or riveting and the telescopic link 411 of pneumatic cylinder for the flexible of the telescopic link 411 of pneumatic cylinder can drive the movable block and remove in spout 322. In order to reduce the friction between the moving block and the inner wall of the sliding groove 322, rolling elements such as corresponding balls can be arranged between the moving block and the inner wall of the sliding groove 322, so that sliding friction is changed into rolling friction, and the friction force is reduced, so that the moving block can move more smoothly.
