Abstract

The utility model discloses a hoisting device with a combined rope pulley. The hoisting device comprises a combined wheel base, wherein a plurality of fixing holes are evenly arranged on the combined wheel base, three or more than three rope pulley axle beds are fixed on the combined wheel base, each rope pulley axle bed is respectively provided with a rotation shaft and a rope pulley, and the circle center of the circular arc connecting line of tangent points of each hub of the rope pulley with a hoisting cable is inosculated with the circle center of an alternative rope pulley with large diameter. The hoisting device with a combined rope pulley is safe, reliable, economic and practical, lightens the deadweight of the rope pulleys, greatly reduces the consumption of raw materials, reduces the cost of production, installation and maintenance, and has small occupied building space, low cost, energy conservation and environment protection.

Description

Bont with combined type rope wheels

Technical field

The utility model relates to a kind of bont, more particularly, relates to a kind of bont with combined type rope wheels.

Background technology

At present, be widely used in the jacking equipment of vertical transportation means of delivery in the building, main is made up of towing machine (winch), guide rail, counterweight, safety device (as velocity limiter, safety tongs and energy disperser etc.), signal manipulation system, car and Room door etc.And wherein be arranged on major diameter rope sheave 1 in machine room, pulley room or the hoistway, as shown in Figure 3, its diameter and volume are bigger, need occupy bigger space, safeguard for the ease of installing and changing, and also need to reserve bigger service clearance; And headspace also needs steel structure to realize, has been bigger for the consumption of steel resources since like this; Because major diameter rope sheave 1 volume is big, Heavy Weight, brought difficulty for installation and replacing; Because the quantity of major diameter rope sheave 1 is one, steel rope need be adjusted into relaxation state during replacing, therefore, need lift by crane the work that car etc. is wasted time and energy.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of bont with combined type rope wheels, and its combined type rope wheels is not only safe and reliable but also economical and practical, and the rope sheave weight reduction significantly reduces raw materials consumption, reduces manufacturing, installation and maintenance cost; And the space that takies is little, cost is low, energy-conserving and environment-protective.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of bont with combined type rope wheels, include the combination wheel base, on the combination wheel base, be evenly distributed with the plurality of fixed hole, be set with the rope sheave axle bed more than three or three on the combination wheel base, be separately installed with turning cylinder and rope sheave on each rope sheave axle bed, the center of circle of the circular arc line of outer hub of each rope sheave and lifting cable points of tangency matches with the center of circle of the major diameter rope sheave that is substituted.

Adopt the beneficial effect after the technique scheme to be: the bont with combined type rope wheels of the present utility model, its rope sheave are compound type, can save time, installing space and structure of steel product thereof; When changing rope sheave, can change one by one and need not to make steel rope to loosen; And when if just one of them in the combination wheel need be changed, its cost is lower than the cost of changing a whole rope sheave.

Description of drawings

Fig. 1 is the structural representation with bont of combined type rope wheels of the present utility model;

Fig. 2 is the another structural representation with bont of combined type rope wheels of the present utility model;

Fig. 3 is the prior art constructions scheme drawing.

Wherein, 1 major diameter rope sheave, 2 rope sheaves, 21 promote cable, 22 combination wheel bases.

The specific embodiment

Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.

As shown in Figure 1, bont with combined type rope wheels of the present utility model, include combination wheel base 22, on combination wheel base 22, be evenly distributed with the plurality of fixed hole, be set with the rope sheave axle bed more than three or three on the combination wheel base 22, be separately installed with turning cylinder and rope sheave 2 on each rope sheave axle bed, the center of circle of the circular arc line of the outer hub of each rope sheave 2 and lifting cable 21 points of tangency matches with the center of circle of the major diameter rope sheave that is substituted.

Combination wheel base 22 in the bont with combined type rope wheels of the present utility model can adopt concrete pedestal to substitute, and need not increase base in addition.

Figure 1 shows that the structural representation of the rope sheave 2 that promotes cable 21 lower ends, and the structure of the rope sheave 2 of lifting cable 21 upper ends as shown in Figure 2, its principle of work and structure composition are grasped by those skilled in the art easily, do not repeat them here.

Rope sheave in the bont with combined type rope wheels of the present utility model is a compound type, can save time, installing space and structure of steel product thereof; When changing rope sheave, can change one by one and need not to make steel rope to loosen; When in the combination wheel one of them need be changed, its cost was lower than the cost of changing a whole rope sheave.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.

Claims

1. bont with combined type rope wheels, include the combination wheel base, on the combination wheel base, be evenly distributed with the plurality of fixed hole, it is characterized in that: be set with the rope sheave axle bed more than three or three on the combination wheel base, be separately installed with turning cylinder and rope sheave on each rope sheave axle bed, the center of circle of the circular arc line of outer hub of each rope sheave and lifting cable points of tangency matches with the center of circle of the major diameter rope sheave that is substituted.
