Description

Technical Field

[0001] The invention belongs to the technical field of hoisting, and in particular relates to a hoisting device used for assembling an electric power tower. Background Art

[0002] During the assembly of power towers, various tools and other goods need to be hoisted frequently. In the assembly of power towers, cranes can play an important role, especially in construction sites with convenient transportation or when a large number of components need to be hoisted quickly. However, cranes have high requirements for the site. They need a solid and flat ground to support their own weight and the lifting weight when working. If the ground at the construction site is soft, such as in some wetlands or uncompacted land, the crane's legs may sink, causing the crane to become unstable. Power towers are mostly built between high mountains and steep hills, making it difficult for cranes to reach the site.

[0003] The pulley block is used to change the direction of force and save effort during the hoisting process of the power tower assembly. The pulley block suspends the parallel ascending and descending slings downwards, but it is necessary to equip a dedicated person or special equipment to draw the tail rope of the descending sling. Moreover, the distance between the ascending and descending slings is only the width of the pulley. The distance between the ascending and descending slings is very close, and the hoisted goods are easily entangled with the ascending and descending slings during the hoisting process, causing hoisting failure and safety risks.

[0004] Therefore, there is an urgent need for a lifting device for assembling an electric tower to solve the problem that the distance between the ascending section sling and the descending section sling suspended downward by the pulley block in the prior art is very close, and the lifted cargo is easily entangled with the ascending section sling and the descending section sling during the lifting process, resulting in lifting failure. Summary of the invention

[0005] In view of the above analysis, the present invention aims to provide a lifting device for assembling an electric tower, so as to solve the problem in the prior art that the ascending section sling and the descending section sling suspended downward from the pulley block are very close to each other, and the lifted cargo is easily entangled with the ascending section sling and the descending section sling during the lifting process, resulting in lifting failure.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions:

[0007] A lifting device for assembling an electric power tower comprises a pull rope unit, a suspension unit and a first pulling unit. The first pulling unit is arranged on a support leg of the electric power tower, the suspension unit is arranged on a crossbeam of the electric power tower, the pull rope unit is a rope loop, the pull rope unit is connected to the suspension unit and the first pulling unit in sequence, and the pull rope unit is used to lift goods from the ground to the crossbeam of the electric power tower.

[0008] Furthermore, it also includes a winch, which is arranged on the supporting foot and is used to make the pull rope unit rotate around the suspension unit and the first pulling unit.

[0009] Furthermore, it also includes a second pulling unit, which is arranged on the supporting leg. The pull rope unit is connected to the second pulling unit, and the pull rope unit is a triangular rope loop. The hanging unit is located at the top corner of the pull rope unit, and the first pulling unit and the second pulling unit are respectively located at the two bottom corners of the pull rope unit.

[0010] Furthermore, the first pulling unit and the second pulling unit have the same structure.

[0011] Furthermore, the pulling rope unit includes a sling and a hook, and the hook is used to be connected with the cargo and hook up the cargo.

[0012] Furthermore, the suspension unit comprises a suspension pulley and a suspension hook, the suspension pulley and the suspension hook are rotatably connected, the suspension hook is used to be connected to the crossbeam, and the suspension pulley is used to be connected to the sling.

[0013] Furthermore, the first pulling unit includes a pulling pulley, a transfer buckle and a connecting seat, the pulling pulley is rotatably connected to the transfer buckle, and the transfer buckle is rotatably connected to the connecting seat.

[0014] Furthermore, the pull rope unit also includes a connecting assembly, and the hook and the connecting assembly are respectively arranged at two ends of the sling.

[0015] Furthermore, the connecting assembly includes a connecting block, on which a connecting groove is provided, and one end of the sling can be inserted into the connecting groove.

[0016] Furthermore, the connecting assembly also includes a connecting bolt, which is threadedly connected to the connecting block. By rotating the connecting bolt, the end of the connecting bolt can squeeze the sling toward the side wall of the connecting groove, so that the sling is connected to the connecting groove and prevents the sling from detaching from the connecting block.

[0017] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0018] (1) The rope pulling unit of the lifting device of the present invention forms a triangular rope loop, and the winch causes the rope pulling unit to rotate around the suspension unit, the first pulling unit and the second pulling unit to lift the cargo from the ground to the crossbeam; the rope pulling unit has no tail rope, and no special person is required to draw the tail rope, thus saving manpower; the distance between the ascending section sling and the descending section sling is greater than the width of the suspension unit, and the cargo being lifted is always between the ascending section sling and the descending section sling during the lifting process, and does not contact the ascending section sling and the descending section sling, and does not get entangled with the ascending section sling and the descending section sling, thus ensuring successful lifting and reducing safety risks;

[0019] (2) The lock body and the clamp block of the present invention can clamp the sling, and the clamp block bolt can be threadedly connected to the lock body. Rotating the clamp block bolt can push the clamp block toward the lock body, thereby clamping the sling to prevent the sling from being separated from the lock body; when lifting goods, it can ensure that the hook and the goods are below the rope lock unit;

[0020] (3) The transverse bolt seat of the present invention is arranged on the side wall of the lock body, and the transverse bolt is arranged on the transverse bolt seat. The transverse bolt can pass through the side wall of the lock body and be inserted into the locking groove, thereby blocking the opening of the locking groove and preventing the connecting block from being separated from the locking groove; the lever section is rotated, and the lever section can slide along the inclined end surface and drive the transverse locking section to rotate out of the transverse bolt seat, so that the transverse bolt releases the obstruction of the opening of the locking groove, and the connecting block can be separated from the locking groove. A clamping groove is provided at the vertex of the inclined end surface, and the lever section can be connected to the clamping groove. The clamping groove can limit the rotation of the lever section and prevent the transverse locking section from being inserted into the locking groove; after the lever section is connected to the clamping groove, the user can hold the lock body with one hand and separate the connecting block from the locking groove with the other hand, which is convenient for use and operation;

[0021] (4) The arm plate of the first clamp arm and the arm plate of the second clamp arm of the lifting device of the present invention form a V-shaped clamp arm, which is used to connect with the outer side of the angle steel column. The pulling rod can pass through the angle steel clamp and pull the angle steel clamp toward the arm plate. The angle steel clamp and the arm plate together clamp the angle steel column, thereby connecting the clamp arm assembly to the angle steel column. The first pulling unit and the second pulling unit can be connected to the support foot.

[0022] (5) By pulling the free end of the handle of the present invention, the handle rotates around the rotating shaft and drives the connecting piece and the pulling rod to move toward the connecting seat. Without any tools, the angle steel clamp can be pulled toward the arm plate to clamp the angle steel column.
