Abstract
The utility model relates to a frequency conversion explosion proof bridge type crane, which is characterized in that a heating element of a frequency conversion device in a control box fixedly arranged on the bridge type crane is fixedly connected with a connecting copper plate directly. The control box is sealed by the connecting copper plate, and a heat radiator is connected outside the control box. Control boxes from 2 to 6 are fixedly arranged on the bridge type crane. The utility model efficiently solves a heat dissipation problem of a frequency converter of the frequency conversion explosion proof crane in the control box and provides a good guarantee for the frequency converter widely applied to the bridge type crane. By test, the explosion-proof mode of the control box fully accords to the requirements of national explosion proof standard.
Description
Affiliated field
The utility model belongs to the lifting transport field, especially a kind of frequency conversion overhead explosion-proof crane.
Background technology
Along with the progress of science and technology, frequency converter also is applied on the crane in bridge type gradually.The frequency converter that uses on crane in bridge type is subjected to operating temperature (≤60 ℃) influence bigger, surpass the allowable temperature frequency converter with cisco unity malfunction, and present employed frequency converter only is to be placed in the explosion-proof control box of fully enclosed, there is not cooling measure in this control box, make the temperature in the control box distribute nowhere, make the frequency converter cisco unity malfunction easily; And the heat element of frequency converter self is to link to each other with the radiating gill that carries, the heat-sinking capability of its radiating gill is very limited, usually all there is a fan to help heat radiation on its next door, if directly frequency converter is put into control box like this, not only the heat of frequency converter generation looses and does not go out, fan self also will produce heat, very soon will be in the control box above 60 ℃ (frequency converter heat-resistant limit values), and this has been subjected to considerable restraint with regard to making its application on hoisting crane especially overhead explosion-proof crane.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of heat dissipation problem of frequency converter in control box that solves overhead explosion-proof crane is provided, and is the frequency conversion overhead explosion-proof crane of unpowered heat sinking function.
The purpose of this utility model is achieved in that
This frequency conversion overhead explosion-proof crane, constitute by crane in bridge type, control box, frequency converter, radiator, frequency converter is packed in the control casing, control box is connected with other electric elements of crane in bridge type by cable, it is characterized in that: the heat element that is packed in the frequency converter in the control box on the crane in bridge type directly be connected the copper coin Joint, this connection copper coin encapsulates this control box and connect a radiator outside control box, and the control box that is packed on the crane in bridge type is 2~6.
And described control box is packed on the walking on stage of crane in bridge type by ground screw.
And, the heat element of described frequency converter be connected copper coin and connect copper coin and radiator install all can adopt bolt to install or the silica gel mode affixed.
Advantage of the present utility model and good effect are:
Only be that the radiating gill and the fan that are installed in the frequency converter in the frequency conversion overhead explosion-proof crane control box are dismantled, and on the heat element of frequency converter, pass the control box casing and install and connect copper coin and radiator gets final product, make frequency converter can directly pass through radiator heat-dissipation like this, solved the heat dissipation problem of the frequency conversion explosion-proof crane frequency converter in the control box effectively, for the widespread use of frequency converter on crane in bridge type provides powerful guarantee.By test, the explosion-proof mode of this control box meets national explosion-proof criteria requirement fully.
Description of drawings
Fig. 1 is front view of the present utility model (semi-sictional view);
Fig. 2 is Fig. 1 birds-eye view;
Fig. 3 is the external form enlarged drawing of the utility model control box;
Fig. 4 is that the A-A of Fig. 3 is to cross-sectional view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Be shown as the calabash double-crane in the accompanying drawing of present embodiment, but be not limited to the calabash double-crane.
This frequency conversion overhead explosion-proof crane is supported on the bracket 1, by the crane carriage 9 that moves on girder 8, the girder, constitute with the affixed end carriage 2 of girder, the actuating device 3 that drives the end carriage walking.Be fixed with several control boxs 4 by ground screw 5 walking on stage of crane in bridge type successively on 6, these control box both sides are connected with adjacent control box and other electric elements by cable 7.The control box that is packed on the crane in bridge type is 2~6, is 5 in the present embodiment.
One chamber door 11 is installed on the control box, one frequency converter 13 (bolt installs) is installed in control box, what the heat element 14 of this frequency converter self and control box were outer one is connected copper coin 12 and passes through the affixed or silica gel of bolt (among the figure not label) Joint, this connection copper coin and radiating element 10 are also affixed by bolt and silica gel, being shaped on through hole around this connection copper coin can tighten by bolt with control box, frequency converter is in the fully enclosed housing, satisfies requirement of explosion proof; Form by radiator and radiating gill with the radiator that is connected the copper coin Joint, the connection copper coin is imbedded at the top of radiator fully, embedment length is equal to the width that connects copper coin, be marked with certain amount of fluid in the radiator (before radiator dispatches from the factory, manufacturer carries out), it has heat conduction function efficiently; The heat that the frequency converter heat element produces conducts to radiator by connecting copper coin like this, constantly passes to radiating gill by radiator, and is dispersed in the air.
When install making this control box, the radiating gill and the fan of the frequency converter self of at first will dismantling expose heat element and install and connect copper coin and radiator gets final product.
Through repeatedly experiment, the radiating mode of this no exterior power can satisfy the operating needs of frequency converter fully.
Claims (3)
