Abstract
The utility model discloses a multipoint self-balancing lifting appliance of a cable crane. The multipoint self-balancing lifting appliance comprises two running cars and a multipoint lifting appliance, wherein the two running cars are arranged on a main cable of the cable crane, one of the running cars is connected with a sliding car assembly, and the multipoint lifting appliance is connected with a movable pulley; and a bearing cable is connected between the other end of the sliding car assembly and the other running car, the bearing cable penetrates through the movable pulley on the multipoint lifting appliance, and a lifting cable bypasses the sliding car assembly. In the multipoint self-balancing lifting appliance, the multipoint force bearing of the lifting appliance is changed into single-point force bearing of the movable pulley by members, and lifting weight is uniformly distributed to a crown block of the cable crane by the movable pulley; so that when the members perform multipoint lifting, the uniform multipoint force bearing is realized, and the lifting safety is guaranteed. The multipoint self-balancing lifting appliance is simple in theory, little in investment, fast and convenient in construction, high in safety and strong in adaptability.
Description
Technical field
The utility model belongs to the suspender in the bridge construction, is specifically related to a kind of cable crane suspender.
Background technology
When adopting the cable crane installation component,, then there are four stressed problems of suspension centre of balance if single member needs 4 overhead traveling cranes to lift by crane simultaneously.For guaranteeing lifting safety, following two kinds of solutions are arranged generally:
The one, by 3 points (or 2 points) stressed design Current Collector Sleave and overhead traveling crane.The shortcoming of this method is: the stressed increase of single overhead traveling crane on the one hand, thus cause overhead traveling crane and Current Collector Sleave structure to become big; Be on the other hand member when 3 points (or 2 points) lift by crane, its stress with the distortion must meet the demands, member self strength and stiffness have been proposed high requirement and restriction.
The 2nd, adopt control system, guarantee that 4 suspension centres are stressed evenly.This method requires to control 4 suspension centre synchronized operations, and can monitor the stressed variation of suspension centre in real time and make adjustment, and equipment, control system have been proposed high requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of can cross the cable crane multiple spot self-balancing suspender of realizing self-balancing when lifting, solve 4 lifting synchronisms and stressed homogeneity question, realizes that four suspension centre self-balancings are stressed.
The technical scheme of the utility model is: cable crane multiple spot self-balancing suspender, and it comprises two sport cars on the cable crane main rope, Multiple point hoist, one of them sport car is connected with polyspast, is connected with movable pulley on the Multiple point hoist; Be connected with track cable between the other end of polyspast and another sport car, track cable passes the movable pulley on the Multiple point hoist, and hoisting line is walked around polyspast.
Be connected with suspender belt between said Multiple point hoist and the movable pulley.
Be connected chain block between said Multiple point hoist and the movable pulley.
Said polyspast comprises first sport car bonded assembly assembly pulley and the running block, and said hoisting line passes assembly pulley and running block.
The utility model is walked around movable pulley through two sport cars of cable crane one side through the polyspast of track cable and lifting and is formed single suspension centre; Movable pulley is connected through suspender belt with Multiple point hoist again; And through the discrepancy in elevation before and after the chain block adjustment suspender of arranging between movable pulley and Multiple point hoist; Thereby adjustment member longitudinal gradient, stressed to be adjusted into the movable pulley single-point stressed by the suspender multiple spot can to realize member, through movable pulley lift heavy all assigned to two sport cars again.Its advantage is following:
1) input is little, cost is low
This device is through simple lever principle, on the basis that does not increase equipment, receive through a movable pulley and Multiple point hoist realization member multiple spot force self-balanced, drop into little, cost is low.
2) adaptive capacity is strong
This device is realized the longitudinal gradient adjustment through the chain block that is provided with between movable pulley and Multiple point hoist, and can solve the different problems of component gravity center through on suspender, using different suspension centres, and adaptive capacity is strong.
3) safe
This device can guarantee that a plurality of suspension centres are stressed evenly, thereby guarantees lifting safety.
Description of drawings
Fig. 1 cable crane multiple spot self-balancing suspender scheme drawing.
The specific embodiment
As shown in Figure 1, cable crane main rope 1 is provided with two sport cars 2.1,2.2, is connected with polyspast 4 on the sport car 2.2, and polyspast 4 comprises and sport car 2.2 bonded assembly assembly pulleys 4.1, and running block 4.2, and hoisting line 11 is walked around assembly pulley 4.1 and running block 4.2.
Be connected with track cable 3 between the lower end of running block 4.2 and the sport car 2.1.
Multiple point hoist passes through hoist cable 9 for 7 times and realizes the connection lifting to member 10.
Multiple point hoist 7 is connected with movable pulley frame 5.1 through chain block 8, connects movable pulley 5 on the movable pulley frame 5.1, and track cable 3 is walked around movable pulley 5.Be connected with suspender belt 6 between movable pulley frame 5.1 and the Multiple point hoist 7.
