Abstract
The utility model discloses a mechanism for replacing an auxiliary hoisting wire rope of a four-beam four-rail dual-trolley bridge crane. The mechanism comprises a primary trolley mechanism and an auxiliary trolley mechanism which are mounted above and below a horizontal frame; two I-section steel bases are respectively placed on bent inner walls at the two sides of the horizontal frame; a horizontally-arranged I-section steel rail is connected to the top faces of the middle parts of the two I-section steel bases through welding; a winch with travelling wheels is mounted on the I-section steel rail in a hanging manner; and the travelling wheels horizontally run along the I-section steel rail. The mechanism has the advantages that the structure is simple, the auxiliary hoisting wire rope of the crane can be conveniently replaced through the winch, and the use is timesaving and laborsaving.
Description
Technical field
The utility model relates to more converting mechanism of the secondary hoist rope of a kind of four beams, four rail double trolley crane in bridge type.
Background technology
Metallurgy industry is for the continuous lifting of productive capacity at present, and the ability of plant maintenance is also being continued to optimize.When changing the secondary hoist rope of four beams, four rail double trolley, consider that span is high 30 meters in the past, just must use one of 50t tire wheel crane, and when change steel rope more, need 16m * 9m=144m
2The occupation of land scope of work; Perhaps use hoisting crane maintenance electric winch, it is out of service with adjacent hoisting crane to coordinate production when using electronic elevator.These two kinds of methods are restricted by expense, time, place and manpower all can.It is existing because the metallurgical system rhythm of production is tight; Use the purpose of 50t tire cranemobile and maintenance electric winch just two chicken core riggings of steel wire end to be hung crane in bridge type; The weight altogether of two chicken core riggings also just has only about one ton, so these two kinds of methods are not actv. ways.
Summary of the invention
The purpose of the utility model is to provide more converting mechanism of the secondary hoist rope of a kind of four beams, four rail double trolley crane in bridge type, and it is simple in structure, can change the secondary hoist rope of hoisting crane easily, uses the save trouble and labor.
The purpose of the utility model is to realize like this; The secondary hoist rope of a kind of four beams, four rail double trolley crane in bridge type is converting mechanism more; Comprise the main carriage mechanism and the secondary trolley body that are installed in the horizontal frame upper and lower; On the both sides of horizontal frame bending inwall, placing an I-beam section base respectively; Be welded to connect the i-beam track of a horizontal arrangement on the two I-beam section base middle top surface, hanging on this i-beam track the winch with road wheel is installed, road wheel is along said i-beam track level run.
The utility model is simple in structure, and job procedure is simplified in (1), and the once mounting one would be set for life does not need repeated disassembled and assembled, and is simple to operate, need not employ crane and electric block.(2) save replacing auxiliary hook steel rope replacing time 20%-50%, improved maintenance of equipment work efficient.(3) practice thrift the manpower 50% of changing secondary hoist rope, and reduced labour intensity.(4) reduced the direct influence of plant maintenance to producing.(5) directly reduce each crane usage charges 10,000-1.5 ten thousand.Agency cost is 2000 yuan.Can change the secondary hoist rope of hoisting crane easily through winch, use the save trouble and labor.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure scheme drawing of the utility model.
The specific embodiment
The secondary hoist rope of a kind of four beams, four rail double trolley crane in bridge type is converting mechanism more; As shown in Figure 1; Comprise the main carriage mechanism 1 and the secondary trolley body 5 that are installed in horizontal frame 3 upper and lowers; On the both sides of horizontal frame bending inwall, place an I-beam section base 4 respectively, do not having fixed connection structure between I-beam section base 4 and the horizontal frame 3, do not hindering the stressed and Stability Analysis of Structures of horizontal frame.Be welded to connect the i-beam track 2 of a horizontal arrangement on two I-beam section bases, 4 middle top surface, hanging on this i-beam track 2 winch 6 with road wheel 7 is installed, road wheel 7 is along said i-beam track 2 level runs.The utility model is simple in structure, can change the secondary hoist rope of hoisting crane easily through winch 6, uses the save trouble and labor.
Claims (1)
1. the secondary hoist rope of beam four rail double trolley crane in bridge type converting mechanism more; Comprise the main carriage mechanism and the secondary trolley body that are installed in the horizontal frame upper and lower; It is characterized in that: on the both sides of horizontal frame bending inwall, placing an I-beam section base respectively; Be welded to connect the i-beam track of a horizontal arrangement on the two I-beam section base middle top surface; Hang on this i-beam track the winch with road wheel is installed, road wheel is along said i-beam track level run.
