Description
Technical field
The utility model relates to forklift transport arm technical field, relates in particular to a kind of yoke.
Background technology
Fork truck is industrial transportation vehicle, refer to member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short range hauling operation, fork truck comprises driving vehicle and is arranged on the yoke of driving vehicle front end.
In the installation process of the current current transformer at 35kV switch cubicle inner bottom part, generally need to use fork truck, current transformer is the visual plant of connecting valve and outlet, its installation site is fixed, major part is all positioned at darker position, switch cubicle bottom, the front rear cabinet door distance of distance is all larger, there is certain installation depth, simultaneously, when needs are changed current transformer, the busbar that is positioned at current transformer top is not generally removed, the current transformer that volume is larger so out or when entering is easily blocking, simultaneously, the bottom of current transformer is mounted on two spaced bending plates, generally to pull up after current transformer is sent to assigned address by fork truck.
Therefore, install and have following various problems:
1, inside switch cabinet narrow space, owing to lacking suitable mounting tools, causes the work efficiency of dismounting CT low, and has security risk;
2, narrow space in switch cubicle, and CT is positioned at inner darker position, and other equipment such as line conductor row, cable that are added with outward exist, and service personnel creeps into and gets out, and installs and dismantles very inconvenient;
3,35kV current transformer used is all heavier, much all surpasses 80kg, only depends on before and after rope binding and pull and place during dismounting, and most current transformers are smooth in appearance, at all without stress point, mobile very painstaking;
4, because there is the jut of " thresholds " such as the different channel-section steel of height, band iron, cables on ground, exist, pull effort, and easy generation collided with in pulling process, cause the damage of current transformer porcelain patticoat, bring device security risk;
5, cannot the application of force owing to installing, and easily skid, thus in narrow space, often occurring that personnel slip out of the hand causes colliding with and wound of personnel;
6, the current free-hand mounting means that pulls, one group of CT needs at least 4 personnel, installs more than single CT needs half an hour, and one group of three CT at least needs two hours, and work efficiency is very low.
There is following various problems in replacing:
1) in switch cubicle installation process, base current transformer is just installed the busbar that connects current transformer after installing, yet in changing current transformer process, busbar is not generally removed, cause the height of leaving new clothes current transformer for almost there is no surplus, easily card is firm when inserting wherein for the current transformer that volume is very large;
2) no matter at the positive or back side of switch cubicle, pull current transformer in switch cubicle reserved location, switch cubicle inner bottom part is not plane, but exist " thresholds " such as the different channel-section steel of height, band iron, cables, if use the method pulling, make heavy CT cross these " thresholds ", service personnel is not easy to borrow power in small space on the one hand, easily produces and collides with on the other hand, the insulation of current of injury transformer in the process of crossing;
3) current transformer is installed on two symmetrical bending plates, it between two bending plates, is the space of about 20cm, and bending plate and busbar spacing just in time can be passed through a current transformer, if pull current transformer in process, can not pass through the gap of two bending plates by pulsation-free, there will be by bending plate and busbar and block up and down firm situation.
Yoke self on the special forklift using at present only can be realized and moving forward and backward and oscilaltion, but cannot realize sway, can not adapt to the installation environment of the current transformer in small space, uses very inadequate.
Therefore, how providing a kind of yoke, to realize the sway of yoke, is current those skilled in the art technical matterss urgently to be resolved hurrily.
