Abstract
The utility model relates to an auxiliary exchanging block tray which is arranged on a block. A tray body is in a C-shaped structure. The upper part of the utility model is provided with an adjustment bolt. One end of the adjustment bolt is abutted against the top of a block bracket. The lower part of the utility model is sheathed at the bottom of the block bracket. The lower part of the tray is separated. The tray of the utility model is sheathed on the block under the condition that the small block is stationary, the block and H-shaped steel are lifted by the adjustment bolt. A pulley and a bracket steel plate are not stressed by the gravity of cables. The damaged pulley and the damaged bracket steel plate are exchanged to repair the damaged small block.
Description
Technical field
The utility model belongs to hoisting crane mechanical equipment field, particularly hoisting crane flight-line maintenance equipment.
Background technology
The control power lead of hoisting crane electric flat carriage generally all adopts following several method:
Removal cable jigger, the magneto striction wire turn of stumbling, they are moving along with electric flat carriage in the course of the work, one is that the jigger that moves and then moves together, drive is suspended on the control cable on the jigger, another be with cable on the wire turn of stumbling that moves together along with the hoisting crane electric flat carriage, the wire turn inside of stumbling is a direct current and the electrical motor that exchanges, and the stumble moment of wire turn of control is come the tension force of control cable line.Yet particularly at large-tonnage, the most employing hung control cable under the mobile jigger on hoisting crane, and its outstanding advantage is not need the energy, is passive moving, and is to move along with the operation conditions of electric flat carriage.The radical of removal cable can very very much not be subjected to the influence of volume in addition, and it is a state of nature at motion process, cable is moved repeatedly do not damage inner structure, installs simple and direct.
If but the tonnage of hoisting crane is big, the capacity of the cable that is bound to also increases.
The mobile jigger of 100 tons of monkeies of frequency conversion driving, every jigger will hang over one hundred jin cable down, owing to often use the jigger that moves to regularly replace.Changed jigger must be by electric block in the past, and the several people holds up cable together and could change.Change a jigger and generally need about two hours; and require great effort very much; labour intensity is big; the hoisting crane rush repair also have the position of electric block to fix, if must influence the normal use that closes on hoisting crane; because the track that driving is moved is blocked in the dust; totally unfavorable to large-scale production, similarly situation takes place repeatedly, has influenced normal production.So in the time of repairing all is in a rush, is easy to generate safety misadventure.
Summary of the invention
The purpose of this utility model is to provide a kind of auxiliary transposing coaster carriage, can solve a lot of inconvenience that hoisting crane is changed jigger.
For achieving the above object, the technical solution of the utility model is,
Auxiliary transposing coaster carriage is arranged on the coaster, and bracket body is the C font structure, and top is provided with the adjusting bolt, and an end of this adjusting bolt is resisted against the top of coaster support, and its underpart is sheathed on the bottom of coaster support.
Described carriage bottom jag.
Under the static situation of jigger, carriage of the present utility model is enclosed within on the coaster, by regulating bolt coaster and I-beam section is soared, pulley and support steel plate are not subjected to the gravity of cable, by changing pulley and the support steel plate that damages, reach and repair the jigger that damages.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, auxiliary transposing coaster carriage of the present utility model, be arranged on the coaster 3, bracket body 1, be the C font structure, top 11 is provided with regulates bolt 2, and an end of this adjusting bolt 2 is resisted against the top of coaster support 31, its underpart 12 is sheathed on the bottom of coaster support 31, described carriage bottom 12 jags.
Coaster 3 is made up of support 31, pulley 32, bolt and nut 33, cable clamp 34, is installed in the I-shaped steel tank 4, can move after stressed.Generally speaking, coaster 3 lower end suspended cables parts can not damaged substantially, mainly are that pulley 32, support 31 steel plates damage, and therefore changing coaster mainly is to change pulley 32 and support 31 steel plates.
Under the static situation of jigger, carriage of the present utility model is enclosed within on the coaster 3, by regulating bolt 2 coaster 3 and I-beam section is soared, pulley 3 and support 31 steel plates are not subjected to the gravity of cable, by changing pulley 3 and support 31 steel plates that damage, reach and repair the jigger that damages.
