Abstract
The invention relates to a high-load double-track trolley which is characterized by comprising two parallel bases on the same horizontal plane, rollers arranged at the bottoms of the bases and used for travelling on tracks, a support vertically erected on the two bases, and at least one lifting mechanism fixed on the support, wherein the support is connected with one base through two bolts and with the other base through a bolt; and the bolts are located on the same horizontal plane. According to the high-load double-track trolley, on the one hand, at least one lifting mechanism is fixed on the support, so that the corresponding number of lifting mechanisms can be arranged according to the weight of a lift article; on the other hand, the support is connected with one base through the two bolts and with the other base through the bolt, so that four wheels are contacted with the tracks simultaneously when the double-track trolley is in use, and no three-leg phenomenon appears.
Description
Technical field
The invention belongs to hoisting crane technical field, be specifically related to a kind of high load-carrying double track dolly.
Background technology
Hoisting crane (claiming again crane) refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, for material handling, by version, can be divided into small-sized weight-lifting equipment, bridge (bridge-type, transfer crane), boom type (self-propelled, tower, seat type, railway formula, floating vessel type, derrick crane), cable type etc.Wherein, bridge crane can oblong place and on idle job, be used for the Article handling that workshop, warehouse, open storage etc. are located, be divided into beam crane, crane in bridge type, gauntry crane, cable crane, crane bridge etc., and beam crane mainly comprises mono beam crane in bridge type and twin beam overhead bridge crane.The advantage of twin beam overhead bridge crane is lifting wider range, can lift by crane the article of 1 ton ~ 100 tons.
High load-carrying double track dolly refers to for lifting by crane 50 tons of above article, thereby higher to its requirements for quality, in use, must not occur that " three leg " phenomenon (is that car wheel only has three to contact with track, another is unsettled), otherwise easily cause double track dolly discontinuity, affect its service life.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art one to there will not be the high load-carrying double track dolly of " three leg " phenomenon.
For achieving the above object, the technical solution used in the present invention is: a kind of high load-carrying double track dolly, it is characterized in that: it comprise two be parallel to each other and the pedestal in a horizontal surface, be located at base bottom for the roller of walking in orbit, vertically stand on two supports on pedestal, be fixed at least one derricking gear on support, described support is connected by two latches with one of them pedestal, be connected by a latch with another pedestal, described latch is in same level.
Optimally, described derricking gear comprise the reel that is fixed on support, be fixed on support motor for power is provided to reel, be located at reel below running block, be fixed on running block bottom suspension hook, connect the hawser of reel and running block.
Further, the latch that described support is connected with another pedestal is pin.
Because technique scheme is used, the present invention compared with prior art has following advantages: the high load-carrying double track of the present invention dolly, by fix at least one derricking gear on support, the derricking gear of respective number can be set according to the weight of lifting article on the one hand; Support is connected by two latches with one of them pedestal on the other hand, and is connected by a latch with another pedestal, makes double track dolly guarantee that in use four wheels contacts track simultaneously, there will not be " three leg " phenomenon.
Accompanying drawing explanation
The structural representation that accompanying drawing 1 is the high load-carrying double track of the present invention dolly;
Wherein, 1, pedestal; 2, roller; 3, support; 31, latch; 32, latch; 4, derricking gear; 41, reel; 42, motor; 43, running block; 44, suspension hook; 45, hawser.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated.
High load-carrying double track dolly as shown in Figure 1, mainly comprises pedestal 1, roller 2, support 3, derricking gear 4.
Wherein, pedestal 1 is two, and they are parallel to each other and in a horizontal surface; Roller 2 is located at pedestal 1 bottom, for above walking at track (twin beams); Support 3 vertically stands on two pedestals 1, and is fixed with at least one derricking gear 4, and support 3 is connected by two latches 31 with one of them pedestal 1, is connected by a latch 32 with another pedestal, and these three latches 31,32 are in same level.By fix at least one derricking gear 4 on support 3, the derricking gear 4 of respective number can be set according to the weight of lifting article, and support 3 is connected by two latches 31 with one of them pedestal 1, and be connected by a latch 32 with another pedestal 1, make double track dolly guarantee that in use four rolling 2 contacts track simultaneously, there will not be " three leg " phenomenon.
In the present embodiment, as shown in Figure 1, derricking gear 4 mainly comprises reel 41, motor 42, running block 43, suspension hook 44, hawser 45.Wherein, reel 41 is fixed on support 3; Motor 42 is also fixed on support 3 and is positioned at a side of reel 41, for providing power to reel 41; Running block 43 is positioned at the below of reel 41, and its bottom is fixed with suspension hook 44; Hawser 45 is arranged on reel 41 and running block 43.In order to make support 3 and the activity slightly of another pedestal 1, the latch 32 of connection is pin.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
