Description
Technical field
The utility model belongs to the elevator machinery field, particularly a kind of electric block and use the hoisting crane of this electric block.
Background technology
The gate-type single-beam crane of employed medium and small tonnage or the jack up unit of indoor employed single-beam crane often adopt electric block at present.The electric block of common horizontally set mainly comprises running gear and jack up unit on the market; running gear comprises the trolley drive motor that is used to be installed in girder i-beam track upper roller and is used for the driving rolls operation; jack up unit mainly comprises reel that is wound with steel rope on it and the suspender that is suspended on the reel below by steel rope; reel is driven by lifting motor, usually also is provided with rope guide, lifting altitude inhibiting device on the electric block and the load limiter that is used to prevent overload etc.During use electric block is installed on the I-beam section of girder, roller moves at the driving lower edge of trolley drive motor I-beam section bearing of trend, this moment, the axis of reel was parallel with the orbit of electric block, the operation plane keeping parallelism of the axis of reel and roller, but so when practical application, just exist not enough.Such as, when using the indoor single-beam crane handling object very near to be apart from the workshop body of wall, if use above-mentioned conventional electric block, because the lateral length of its reel is bigger, add the length of reel housing, often cause whole electric block can't reach the assigned address of girder side, always and between the body of wall there is certain distance, want the words of handling weight, just need tiltedly drawing of wide-angle, wide-angle tiltedly draw the wide swing that can cause electric block, often cause extra collision, and there is bigger potential safety hazard in large-angle inclined being pulled in when using, when particularly being applied on the gate-type single-beam crane to electric block, wide-angle tiltedly draw the easier safety misadventure that causes, occur transfer crane easily and topple.
The utility model content
The purpose of this utility model provides a kind of electric block, uses the electric block handling to occur large-angle inclined technical matters of drawing often near wall article in the prior art to solve; The utility model also provides a kind of hoisting crane that uses this electric block simultaneously.
The technical scheme of the electric block that is provided in the utility model is: a kind of electric block, comprise running gear and jack up unit, running gear comprises the roller that is used for corresponding walking cooperation with the crane girder track, jack up unit comprises that the below is hung with the reel of suspender, and the axis of described reel is consistent with the bearing of trend of roller pivot center.
Described roller is installed on the turning rolls, is fixed with the flat-topped ridge device in turning rolls bottom, and the reel housing that is used to install reel is connected in flat-topped ridge device bottom.
On the described reel housing rope guide that is used for the guide wire rope is installed under roller.
When the utility model electric block is installed on the hoisting crane, because the axis of reel is vertical with the operation plane of roller, when roller moved on the girder I-beam section like this, spool axis was vertical with the bearing of trend of girder I-beam section, and this moment, the reel of electric block was vertically to be provided with.When needing the article of the close body of wall of handling, electric block can move to a side of crane track to greatest extent so that the lifting article, thereby solve large-angle inclined problem of drawing,, improved hoisting crane single-piece safety performance because avoided large-angle inclined operation of drawing.During near the article of body of wall, its required oscillating quantity is little in needs liftings for electric block in the utility model, safety performance height during use, the damage of avoiding the electric block of original horizontally set to be subjected to because of extra collision.And because adopted the reel of vertical setting, what electric block had farthest enlarged the workshop when real work laterally utilizes the space, has improved the workshop utilization of space.
The hoisting crane technical scheme that is provided in the utility model is: a kind of hoisting crane that uses electric block, comprise girder, operation has electric block on the girder track, electric block comprises running gear and jack up unit, running gear comprises the roller that operates on the girder i-beam track, jack up unit comprises that the below is hung with the reel of suspender, and the axis of described reel is consistent with the bearing of trend of roller pivot center.
Described roller is installed on the turning rolls, is fixed with the flat-topped ridge device in turning rolls bottom, and the reel housing that is used to install reel is connected in flat-topped ridge device bottom.
On the described reel housing rope guide that is used for the guide wire rope is installed under roller.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model hoisting crane;
Fig. 2 is the structural representation of electric block among Fig. 1;
Fig. 3 is the lateral plan of Fig. 2.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of hoisting crane that uses electric block, comprise girder 1, operation has electric block 3 on I-beam section 2 tracks of girder 1, electric block 3 comprises running gear and jack up unit, running gear comprises roller 13 that operates on the girder i-beam track and the trolley drive motor 7 that is used for the driving rolls operation, roller 13 is installed on the turning rolls 14 of electric block, be fixed with flat-topped ridge device 11 in turning rolls 14 bottoms, the reel housing 15 that is used to install reel is connected in flat-topped ridge device 11 bottoms, jack up unit comprises and is rotatably installed in reel housing 15 in-to-in reels, reel is lifted with suspender 9 by the steel rope that twines thereon, on the reel housing 15 with under the roller 13 rope guide 6 that is used for guide wire rope 4 is being installed, reel is driven by reductor by the lifting motor 5 that is arranged in the reel housing, the axis of reel and the turning cylinder of roller to bearing of trend consistent, lifting altitude inhibiting device and load limiter also are installed on the electric block.
As shown in he Fig. 3, jack up unit in the present embodiment adopts row's rope in pairs, so just can guarantee suspension hook moderate be positioned at girder under, guarantee the stressed moderate plane of symmetry that is arranged in girder of girder, with stablizing of guaranteeing that whole hoisting crane moves.Among Fig. 3, be provided with two to rope guide 6 with the double rope of reel is corresponding.
The electric block that vertically is provided with in the utility model is mainly used in indoor portal formula single-beam crane, the gate-type single-beam crane that also can be used for outdoor medium and small tonnage, thereby avoid when hoisting crane lifts the article of close wall, adopting large-angle inclined mode of drawing by the reel of vertical setting, improve the safety performance of hoisting crane and electric block, reduce the safety misadventure incidence.
Adopt the electric block that vertically arranges in the utility model can more close body of wall during near the weight of prerequisite in lifting than the electric block of available technology adopting horizontally set, utilize to greatest extent the horizontal space in workshop, generally speaking, the position of longitudinally electric block and horizontal electric block operation can differ from about 600mm, can enlarge and utilize about the 1500mm of space, and when the big and workshop height of electric block lifting capacity and lifting altitude was low, it is more obvious that this effect embodies.
