Abstract
The utility model relates to the field of a bridge type crane and particularly relates to a double-beam bridge type crane of an electric hoist. The double-girder bridge type crane comprises a main beam and the main beam is provided with a travelling trolley; wheels are arranged on the periphery of the travelling trolley; an adjusting mechanism is arranged between one pair of the wheels at the two opposite sides and a power mechanism is connected with one wheel of the other pair of the wheels; a frame body is arranged at the middle part of the travelling trolley and a concave opening is arranged on the frame body; and the electric hoist is arranged in the concave opening. With the adoption of the technical scheme, the adjusting mechanism effectively guarantees that the wheels are positioned in the same plane all the time in an operation process of the travelling trolley, and the operation stability is ensured. Meanwhile, the travelling trolley is provided with the frame body and the frame body can disperse the weight loaded by the electric hoist; and the electric hoist is mounted in the concave opening of the frame body and the head room of the crane is reduced, so that the stability of the operation of the crane is further improved, the height of a plant is also reduced and the production cost is reduced.
Description
Technical field
The utility model relates to the electric crane field, is specifically related to a kind of electric block twin beam overhead bridge crane.
Background technology
In weight-lifting equipment, the electric block twin beam overhead bridge crane is with its oad compactness, advantage is widely used from heavy and light, wheel load be little etc.Electric block twin beams bridge-type crane in bridge type mainly is made up of cart and dolly, cart comprises the girder that be arranged in parallel and the end carriage at girder two ends, be separately installed with the set of wheels that cooperates with track at the two ends of end carriage, dolly comprises and being arranged between two girders along the dolly of girder length direction linear running, and electric block is set on the dolly.Hoisting crane need be sling object at a place in one action, is moved horizontally to another place then and it is put down, and last oppositely return is so that periodical duty next time.Hoisting crane is in each working process, and cart and dolly all need to move around, stable most important in operational process of cart and dolly.The stability of hoisting crane is all relevant with the structure design of its clear headroom, operating unit, dolly especially, and it is directly carrying the weight of object, and dolly must be guaranteed for four jiaos could guarantee the smooth running of hoisting crane in operational process in same plane.
The utility model content
The purpose of this utility model provides a kind of electric block twin beam overhead bridge crane, has lower clear headroom and stronger stability.
For achieving the above object, the utility model by the following technical solutions, the electric block twin beam overhead bridge crane comprises girder, and running trolley is set on the girder, be respectively equipped with wheel around the described running trolley, wherein between a pair of wheel of both sides regulating mechanism is set relatively, another is to a connection actuating unit in the wheel, and the middle part of running trolley arranges support body, recess is set on the support body, and electric block is arranged in this recess.
Described regulating mechanism comprises eccentric shaft, and eccentric shaft is arranged between the wheel of opposite side, also is provided with universal bearing between eccentric shaft and the wheel.
Described running trolley laterally between be provided with the support beam that is parallel to each other, support body is installed between the equalizing bar.
Described support body is set up by two crossbeams that are parallel to each other and two longeron square crossings and is constituted, and two ends and the support beam of longeron are connected, and the middle part of crossbeam arranges recess, and electric block arranges in this recess.
Described actuating unit comprises motor, and motor connects wheel by retarder.
By above technical scheme, regulating mechanism has guaranteed that effectively the wheel of running trolley in operational process, is positioned at same plane all the time, guarantees that it is stable.Simultaneously, at running trolley support body is set, support body can disperse the weight of electric block carrying, and electric block is installed in the recess of support body, reduced the clear headroom of hoisting crane, thereby further improved the stability of hoisting crane operation, also reduced the height of factory building, saved productive costs.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of running trolley;
Fig. 3 is the structural representation of support body;
Fig. 4 is the lateral plan of Fig. 3.
The specific embodiment
Shown in Fig. 1-4, the electric block twin beam overhead bridge crane, comprise girder 7, running trolley 1 is set on the girder 7, is respectively equipped with wheel 2 around the described running trolley 1, wherein between a pair of wheel 2 of both sides regulating mechanism is set relatively, another is to a connection actuating unit in the wheel 2, the middle part of running trolley 1 arranges support body 5, on the support body 5 recess is set, and electric block 6 is arranged in this recess.Regulating mechanism has guaranteed that effectively the wheel 2 of running trolley 1 in operational process, is positioned at same plane all the time, guarantees that it is stable.Simultaneously, at running trolley 1 support body 5 is set, support body 5 can disperse the weight of electric block 6 carryings, and electric block 6 is installed in the recess of support body 6, reduced the clear headroom of hoisting crane, thereby further improved the stability of hoisting crane operation, also reduced the height of factory building, saved productive costs.
Described regulating mechanism comprises eccentric shaft 3, and eccentric shaft 3 is arranged between the wheel 2 of opposite side, and 2 also are provided with universal bearing 4 between eccentric shaft 3 and the wheel.Eccentric shaft 3 and universal bearing 4 can be regulated four wheels 2 automatically all the time in girder 7 operations, guarantee its balance and stability.
Described running trolley 1 laterally between be provided with the support beam 8 that is parallel to each other, support body 5 is installed between the equalizing bar 8.Support beam 8 is being born the weight of the electric block 6 on support body 5 and the support body 5, to the stable crucial effects that plays of whole hoisting crane.
Further, in order to ensure support beam 8 and support body 5 Stability Analysis of Structures, described support body 5 is set up by two crossbeams 51 that are parallel to each other and two longeron 52 square crossings and is constituted, like this, just can when effectively supporting the deadweight and load of electric block 6, alleviate the weight of self.The two ends of longeron 52 and support beam 8 are connected, and the middle part of crossbeam 51 arranges recess, and electric block 6 arranges in this recess.Like this, just can when effectively supporting the deadweight and load of electric block 6, alleviate the weight of self.
Described actuating unit comprises motor 9, and motor 9 connects the wheel shaft of wheel 2 by retarder 10.Motor 9 drives wheels 2 motions by retarder 10, for the crank motion of running trolley 1 provides power.
