The invention relates to a transmission mechanism for an electric hoist. The transmission mechanism for the electric hoist comprises two supporting frames, a connecting piece, a transverse rod, driving gears and driven gears, wherein the two supporting frames are arranged in parallel and are perpendicular to the horizontal plane, the connecting piece is parallel to the horizontal plane and is arranged at the lower portions of the supporting frames in a penetrating mode and used for adjusting the distance between the supporting frames, the transverse rod is arranged in the middles of the supporting frames in a rotatable and penetrating mode, the driving gears are installed on the transverse rod and oppositely arranged on the inner sides of the supporting frames, and the driven gears are arranged on the inner sides of the supporting frames in a rotatable mode and meshed with the corresponding driving gears. The driven gears are arranged above the driving gears, and cylindrical protrusions used for fixing the transmission mechanism to joist steel are arranged on the side faces of the driven gears. According to the transmission mechanism for the electric hoist, on the one hand, due to the fact that the driving gears are installed on the transverse rod and oppositely arranged on the inner sides of the supporting frames, when the driving gear on one supporting frame is driven by a motor to rotate, the driving gear drives the transverse rod to rotate so as to drive the driving gear on the other supporting frame to rotate, and synchronous transmission on the two sides of the transmission mechanism is achieved; on the other hand, due to the fact that the connecting piece is arranged at the lower portions of the supporting frames and used for adjusting the distance between the supporting frames, the requirement for the joist steel of different sizes can be met.
Description
Technical field
The present invention relates to a kind of transmission device, be specifically related to a kind of transmission device of electric block.
Background technology
Electric block is a kind of extraordinary weight-lifting equipment, is installed on overhead traveling crane, gauntry crane, have volume little, from heavy and light, the feature such as simple to operate, easy to use, be widely used in the places such as industrial and mining enterprises, storage harbour, hoisting capacity can reach 80 tons, lifting altitude reaches 30 meters.
Electric block is generally comprised of parts such as electrical motor, transmission device and reel or sprocket wheels.Wherein, transmission device is the important component part of electric block, is related to the service life of electric block.Existing electric block transmission device one side is subject to motor driving, a side is passive moves forward, caused the asynchronous movement of electric block in I-beam section both sides, when electric block bears higher load-carrying, easily cause electric block to run tiltedly, the inner structure of extruding electric block, reduces its service life.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of transmission device that makes the synchronized operation of electric block both sides.
For achieving the above object, the technical solution used in the present invention is: a kind of transmission device of electric block, it comprises and be arrangeding in parallel and perpendicular to two bracing frames of horizontal surface, be parallel to horizontal surface and be arranged in the attaching parts of bracing frame bottom for adjusting support frame spacing, rotatably be arranged in the cross bar at bracing frame middle part, be installed on cross bar and be relatively located at the driving gear of bracing frame inner side, rotatably be located at the driven gear that bracing frame inner side is meshed with corresponding driving gear, described driven gear is located at described driving gear top and its side and is provided with described transmission device is fixed on to the column-shaped projection on I-beam section.
Optimally, described attaching parts comprises fixed link and is fastened on the set collar on fixed link.
Further, support frame as described above outside is provided with for pacifying motorized motor hole, and described motor hole is adjacent with described driving gear and be positioned at below it.
Further, described cross bar is connected with bracing frame by bearing, and described driven gear is connected with bracing frame by bearing.
Because technique scheme is used, the present invention compared with prior art has following advantages: the transmission device of electric block of the present invention, on the one hand by driving gear being installed on cross bar and being relatively located at bracing frame inner side, when rotating under the driving of the driving gear on one of them bracing frame at motor, this driving gear drives cross bar to rotate and then drives the driving gear on another bracing frame to rotate, thereby has realized the synchrodrive of transmission device both sides; In bracing frame bottom, be provided with attaching parts on the other hand, for adjusting support frame spacing, can adapt to the demand of different size I-beam section.

The front view of the transmission device that accompanying drawing 1 is electric block of the present invention;
Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1;
The left view of the transmission device that accompanying drawing 3 is electric block of the present invention;
Wherein, 1, bracing frame; 2, attaching parts; 21, fixed link; 22, set collar; 3, cross bar; 4, driving gear; 5, driven gear; 51, column-shaped projection; 6, motor hole.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated.
The transmission device of electric block as shown in Figures 1 to 3, mainly comprises bracing frame 1, attaching parts 2, cross bar 3, driving gear 4, driven gear 5.Wherein, bracing frame 1 is two, be arranged in parallel and perpendicular to horizontal surface; Attaching parts 2 is parallel to horizontal surface and is arranged in two bracing frame 1 bottoms, for regulating the distance of 1 of two bracing frame; Cross bar 3 is rotatably arranged in bracing frame 1 middle part; Driving gear 4 is two, is installed on cross bar 3 and is relatively located at bracing frame 1 inner side; Driven gear 5 is also two, is rotatably located at bracing frame 1 inner side of driving gear 4 tops and is meshed with corresponding driving gear 4, and their opposite flank is provided with column-shaped projection 51, for transmission device is fixed on to I-beam section.Because two driving gears 4 are installed on rotating cross bar 3, when rotating under one of them driving gear 4 driving at motor, another driving gear 4 synchronously rotates.And, in bracing frame 1 bottom, be equipped with attaching parts 2, for adjusting support frame 1 spacing, can adapt to the demand of different size I-beam section.
In the present embodiment, attaching parts 2 comprises fixed link 21 and is fastened on the set collar 22 on fixed link 21, the easily spacing between adjusting support frame 1.And one of them bracing frame 1 outside is provided with motor hole 6, this motor hole 6 adjacent with driving gear 4 and be positioned at its below, stably mounted motor, it is meshed with driving gear 4, thereby provide power to transmission device, optimize like this structure of transmission device, reduced the space that motor takies.Cross bar 3, driven gear 5 are all connected with bracing frame 1 by bearing.
The above-mentioned structure to electric block transmission device of the present invention is illustrated, and its principle of work is done to brief description below:
In use, first according to the width of I-beam section, the distance that adjusting support frame is 1, utilizes the column-shaped projection 51 on driven gear 5 that whole transmission device is carried on I-beam section, now set collar 22 is fastened on to fixed link 21 1 of bracing frame is clamped on I-beam section; Subsequently bracing frame 1 inner side is fixed and be placed in to the driving gear 4 being installed on cross bar 3.When motor fixing on motor hole 6 is meshed with one of them driving gear 4, this driving gear 4 drives cross bar 3 to rotate and then drives another driving gear 4 synchronously to rotate under the driving of motor, thereby has realized the synchrodrive of transmission device both sides.
