Description
Technical field
The utility model relates to hoisting crane electric supply installation technical field, and a kind of degree of utilization is high specifically, the collector-block that easy access is changed.
Background technology
The hoisting crane that current enterprise uses adopts SDJDG-II type current colector as electric supply installation mostly.The collector-block of this model comprises base, conductive copper sheet, slide block, base, conductive copper sheet, slide block by countersunk-heat bolt and nut from bottom to top run through fixing, the top of countersunk-heat bolt is positioned at the bottom of slide block, and slider bottom contacts current collection with power supply slip, and the height of slide block is about 13mm.The collector-block of this kind of model has the following disadvantages in actual use:
(1), collector-block is the straight consumable component of conduction of hoisting crane, and be mixed by copper and certain proportion graphite, cost is higher.The slide block thickness of this kind of collector-block is 13mm, and countersunk head portion is about 5mm, if add fixing bolt cap, its actual use amount is about about 4mm, namely one piece of thickness is the copper billet of 13mm, its use amount also do not reach three/and cannot use once scrapping, cause very large waste;
(2), the bolt cap of the countersunk-heat bolt of the collector-block of this kind of model needs running check, replacing, to prevent once after bolt cap polished, brush plate will depart from base, scratch with slip and rupture and fall ground, potential safety hazard is brought to ground personnel, cause equipment Loss of power failure, safety is reliable not simultaneously;
(3), routine inspection bolt cap time need to lift brush plate, slip just must have a power failure, and impacts production.In order to reduce impact, during each periodical repair need all slide blocks are checked, fastening and change, need during replacing two people coordinate, one people fixes the current colector pulled down, and another people fixes bolt cap on the other hand, on the other hand with small wrench dismounting opposite side nut, waste time and energy, maintenance cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of collector-block, and to solve, SDJDG-II type collector-block degree of utilization is not high, safety is reliable not, examine and replace difficulty is large, the problem that maintenance cost is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of collector-block it comprise base, conductive copper sheet, slide block, described slide block is provided with internal thread through hole, and described base, conductive copper sheet are fixedly connected with by bolt from top to bottom with described slide block, and the contact surface of described bolt and described base is provided with pad.
As further improvement of the utility model, described bolt is brass system six square bolt.
Further improve as of the present utility model, the height of described slide block is 20mm.
SDJDG-II type collector-block is transformed by the utility model, changes original countersunk screw holes into internal thread through hole, with six square bolts with the use of, the installation from bottom to top of base, conductive copper sheet, slide block fixed, that can fix is tightr; Bolt is made up of brass, and brass is neither too hard, nor too soft, conducts electricity very well, and can participate in attrition together with slide block, can not injure slip; The thickness of slide block increases, and improves the service life of collector-block.
Of the present utility model possess following advantage:
(1), degree of utilization is high, and operating cycles is long, saves expense: although change due to bolt material, slide block thickness increases, and collector-block unit price also increases thereupon, but the collector-block degree of utilization after improving significantly increases, operating cycles extends, and actual operating costs lessens; Install collector-block total amount about 30 pieces online for my unit overhead traveling crane, the average operating cycles of prototype collector-block is approximately 35 days, and collector-block unit price is 162 yuan, the annual collector-block expense about 50,000 yuans consumed; Collector-block unit price after improvement is 235 yuan, and Occupation coefficient can reach more than 80%, and average operating cycles is about 103 days, and the annual collector-block expense about 2.5 ten thousand yuans consumed, can save the expense of half every year;
(2), safety improves: in the utility model, bolt cap is on slide block top, and copper bolt root can wear and tear together with slide block, slide block will being caused to drop because of rubbing bolt cap, improve the safety of use;
(3), overhaul, change convenient and swift: bolt cap top directly screws in, combine closely between base, conductive copper sheet, slide block, operating cycles is longer, can at every turn periodical repair all check, fastening, change, do not need power failure just can estimate bolt whether to loosen, a people is only needed to complete with small wrench is just dismantled and assembled during replacing, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of SDJDG-II type collector-block;
In figure: 1, base, 2, conductive copper sheet, 3, slide block, 4, through hole, 5, bolt, 6, pad.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of collector-block as shown in Figure 1 it comprise base 1, conductive copper sheet 2, slide block 3, slide block 3 is provided with internal thread through hole 4, and base 1, conductive copper sheet 2 are fixedly connected with by bolt 5 from top to bottom with slide block 3, and bolt 5 is provided with pad 6 with the contact surface of base 1.Bolt 5 is brass system six square bolt.The height of slide block 3 is 20mm.
Current colector block after improvement renames SDJDG-III type collector-block as, and (material code is numbered: 443190130037), and install and use at the scene to have applied for material code, effectively raise degree of utilization, save buying and recondition expense, and be convenient to check replacing, use more safe and reliable.Effective solution and compensate for deficiency and the defect of SDJDG-II type collector-block collector-block, can be widely used in the electric supply installation of the hoisting cranes such as crane in bridge type, beam crane, metallurgical special purpose crane.
