Abstract
A crane trolley slide line system comprises a fixing bolt (1), an aluminum mother board (2), a trolley slide line (3), an insulator (6), a red steel paper gasket (7), an angle steel support (8) and bolts (9), wherein the bottom end of the insulator (6) is fixed on the angle steel support (8) via the bolts (9), and the red steel paper gasket (7) is fixed together with the top end of the insulator (6) via the fixing bolt (1). The crane trolley slide line system is characterized in that a channel steel type outer clamping board (5) and a channel steel type inner clamping board (4) are fixed on the red steel paper gasket (7) likewise via the fixing bolt (1); the openings of the channel steel type outer clamping board (5) and the channel steel type inner clamping board (4) are upward; the channel steel type trolley slide line (3) is buckled between the side walls of the channel steel type outer clamping board (5) and the channel steel type inner clamping board (4); a small bolt is arranged on the outer side of the side wall of the channel steel type outer clamping board (5); the aluminum mother board (2) is fixed at the top end of the channel steel type trolley slide line (3). The crane trolley slide line system ensures the completeness of the aluminum mother board and the stability and straightness of the trolley slide line, reduces the occurrence of frequent crane accidents caused by damage to the trolley slide line, guarantees the normal, stable and safe operation of a crane, improves the operating rate and transport ability of the crane, and lowers the cost of spare parts.
Description
Technical field
The utility model relates to a kind of crane trolley.
Background technology
Along with iron-smelter pig iron output rises year by year, the raw material workshop is undertaken 20 tons of clamshell crane operating rates that transport former combustion auxiliary material task and is also strengthened thereupon, as A7 level heavy industry, makes level device.Former being designed to of raw material workshop concentrate store crane trolley: the trolley electric piece that rubs is parallel placement with the aluminium motherboard, in service at crane, the electric piece friction aluminium motherboard that often rubs, the phenomenon that causes trolley junction oxidation ground connection or aluminium motherboard to rupture.When aluminium motherboard ground short circuit, when resistance value increases, it is large that voltage fluctuation becomes, and very easily burns out the electric elements silicon control, also causes the crane component wear simultaneously, causes crane to work.Frequently the trolley fault not only serious restriction production, also increased dimension inspection and spare part expense.
Summary of the invention:
The purpose of this utility model is a kind of aluminium motherboard crack conditions that can not send, and increases a kind of crane sliding contact line system that sliding contact line system reduces service expenditure service life.
The purpose of this utility model is realized by mode once:
A kind of crane sliding contact line system, comprise bolt of rear end plate 1; Aluminium motherboard 2; Trolley 3, insulator 6; Red steel paper packing ring 7; Angle steel bracing frame 8; Bolt 9, the bottom of insulator 6 is fixed on angle steel bracing frame 8 by bolt 9, bolt of rear end plate 1 is fixed together red steel paper packing ring 7 and the top of insulator 6, it is characterized in that: channel steel type external splint 5, channel steel type inner splint 4 also are fixed on red steel paper packing ring 7 by bolt of rear end plate 1, the opening upwards of channel steel type external splint 5 and channel steel type inner splint 4, be buckled with channel steel type trolley 3 between channel steel type external splint 5 and channel steel type inner splint 4 sidewalls, there is stove bolt in the sidewall of channel steel type external splint 5 outside, the fixing aluminium motherboard 2 on the top of channel steel type trolley 3.
Fixedly angle steel bracing frame 8 is two parallel bolts with the bolt 9 of insulator 6.
Advantage of the present utility model:
Change former angle steel trolley into the channel-section steel trolley, and aluminium motherboard and trolley are combined as a whole, the aluminium motherboard is protected in channel-section steel like this, and the electric piece that rubs can't direct impact arrive the aluminium motherboard in operational process, has avoided the angle steel trolley deformation accident produced because of collision.Simultaneously, original porcelain insulator is improved to the bakelite material, to prevent the generation of the frangible phenomenon of porcelain insulator in the electric piece operational process that rubs; Also former connection porcelain insulator bolt is improved at the same time to two bolts and fixes, the electric piece play gap in operational process that reduced to rub, guaranteed that vertical stability is good, makes the unsuitable ground connection of porcelain vase.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: the 1-bolt of rear end plate; 2-aluminium motherboard; The 3-channel-section steel; The 4-inner splint; 5-channel steel type external splint; The 6-insulator; 7-red steel paper packing ring; 8-angle steel bracing frame; The 9-bolt;
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Embodiment 1:
A kind of crane sliding contact line system, comprise bolt of rear end plate 1; Aluminium motherboard 2; Trolley 3, insulator 6; Red steel paper packing ring 7; Angle steel bracing frame 8; Bolt 9, the bottom of insulator 6 is fixed on angle steel bracing frame 8 by bolt 9, bolt of rear end plate 1 is fixed together red steel paper packing ring 7 and the top of insulator 6, it is characterized in that: channel steel type external splint 5, channel steel type inner splint 4 also are fixed on red steel paper packing ring 7 by bolt of rear end plate 1, the opening upwards of channel steel type external splint 5 and channel steel type inner splint 4, be buckled with channel steel type trolley 3 between channel steel type external splint 5 and channel steel type inner splint 4 sidewalls, there is stove bolt in the sidewall of channel steel type external splint 5 outside, the fixing aluminium motherboard 2 on the top of channel steel type trolley 3.
Fixedly angle steel bracing frame 8 is two parallel bolts with the bolt 9 of insulator 6.
By the utility model crane trolley, transform, avoided largely the operational defect of former design trolley, guaranteed intact and trolley firmly straight of aluminium motherboard, the generation of the crane Frequent Accidents phenomenon that minimizing causes because of trolley, guarantee the operation of the normal stability and safety of crane, improve the crane operation rate, increased transport capacity, reduced the spare part expense.
