Background

When the auxiliary device for construction or installation of the power transmission line tower works, pulleys are used, and when a heavy object is hoisted, the existing method mainly comprises two methods, namely rope pulling personnel (shown in figure 1) are added on the ground or pulley sets (shown in figure 2) are used, the ground rope pulling personnel are in short supply and labor cost is increased in busy time, and the method of using the pulley sets is complicated due to the fact that the power transmission line tower is high, the pulley sets are hung on hanging points and object binding points, the object is easy to rotate in the rising process after being lifted off the ground, and ropes among the pulley sets are easy to wind. For example: chinese patent No. CN108862080A, entitled Pulley set in 2018, 11 and 23, entitled parallel Pulley set, including two Pulley bodies with same structure and a steel wire rope connecting the two Pulley bodies, wherein, the Pulley bodies include a connecting part, a protective casing, a big pulley, a small pulley and a fixed shaft, wherein, the big pulley, the small pulley and the fixed shaft are fixed inside the protective casing along the longitudinal direction of the protective casing in turn, the connecting part includes a connecting plate and a U-shaped plate connected with the connecting plate, two side plates of the U-shaped plate are fixedly clamped at two sides of the protective casing, the connecting plate is parallel to the central axis of the big pulley, the steel wire rope passes through the fixed shaft and passes through the small pulley and the big pulley of the two Pulley bodies in turn and then extends out of the protective casing, which has the disadvantages that the rope winding of the Pulley set is troublesome at the hanging point and the binding point of the object, and, the rope between the pulley groups is easy to wind and cannot temporarily suspend the pulling work of the goods.

Disclosure of Invention

The utility model discloses a solve among the prior art hang some and article tie point department pulley block wiring loaded down with trivial details, and article lift the in-process easily beat and change after liftoff, the rope between the coaster block easily twines, can't suspend goods temporarily and pull up the work not enough, provide one kind need not to increase stay cord personnel, reduce labour cost, solve the original coaster block wiring loaded down with trivial details and easily beat and change, the winding problem, can realize the style pulley block that the goods stopped temporarily.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an integral type coaster group, includes monospar, second coaster and connects the hawser of monospar second coaster, monospar and second coaster fixed connection are at the inboard both ends of a pair of splint, the interim winding hook of lateral surface fixedly connected with of splint, it has indent node and evagination node to cross the distribution on the hook to twine temporarily, the indent node is the segmental arc and twine the hook at interim and toward the indent, the evagination node is the segmental arc and twine the hook at interim and toward the outside protrusion, splint are close to one end fixedly connected with ground couple of second coaster. The utility model discloses a monospar and second coaster, connect into an organic whole through a pair of splint, one end fixed connection of splint is a ground couple, ground couple is fixed on the firm component in ground with the short noose, the hawser passes the second coaster in proper order, the monospar, wear out and regard as the stay cord end from the second coaster at last again, another of hawser is first up and pass the hanging point on the iron tower, then it is used for as the end of hanging goods to hang to ground, constructor is at the underrun pulling stay cord end, the lifting and air-lifting of goods is realized by the steering action of integral type coaster group and iron tower hanging point, until reaching the predetermined place, because the monospar, the second coaster passes through splint fixed connection, former coaster group interval has been shortened greatly, and the stay cord end is located the bottom surface that is closer to the stay cord personnel, when the hawser pulling, difficult emergence coaster group is loaded down with trivial, The winding problem, it is unsettled temporarily midway when the goods needs, or the goods reaches the predetermined height, or hang the goods end and be in under the no-load condition, only need with hawser winding on the temporary winding hook not take off can, the cross distribution is interior concave node and evagination node on the temporary winding hook, interior concave node is the segmental arc and toward the outside protrusion on the temporary winding hook, can tie a knot fixedly at interior concave node and evagination node respectively with the hawser when twining, because the hawser is not on the temporary winding hook at the stress point of interior concave node and evagination node, so the department of knoing is difficult to break away from the node, the rope end can be taken with little power just, reduce ground stay cord personnel intensity of labour, thereby can realize the purpose that the goods was berthhed temporarily.

Preferably, a reinforcing support plate is fixedly connected to the clamping plate and penetrates through the clamping plate. The reinforcing support plate can have sufficient strength to support the extrusion between the single tackle and the second tackle after the cable is stressed.

Preferably, the temporary winding hooks are positioned on both sides of the reinforcing support plate and are integrally cast with the reinforcing support plate. Twine the hook and consolidate the integrative structure of backup pad temporarily, intensity is higher more difficult to warp impaired.
