Hoisting crane is used the drop in beam device
The utility model belongs to the weight-lifting equipment field, relates to hoisting crane and uses the drop in beam device.
At present, operations such as the lifting that is widely used in every field, various places of weight-lifting equipment, transportation, the lifting object is various.When the microscler object of lifting, common suspender just can not satisfy the lifting demand, use electromagnet drop in beam device; General electromagnet drop in beam device, the fixed distance of two groups of electromagnet, the length that lifts microscler object has certain restriction; Exceed this scope, just can't satisfy lifting requirements.The lifting mode that needs to change the drop in beam device or adopt other like this, just needs to prepare the crossbeam of many different models, increases financial cost, influences work efficiency.
The utility model content
The utility model technical matters to be solved is: provide a kind of hoisting crane to use the drop in beam device.
The technical scheme that realizes the purpose employing of the utility model is: hoisting crane is used the drop in beam device; But the crossbeam that comprises the level lifting; At least two groups are installed on this crossbeam can drive the hanger bracket that moves along the crossbeam length direction, be equipped with the suspender transom on each hanger bracket by power plant.
Further be that the middle part of said crossbeam also is positioned at its top and is symmetrically installed with two groups and is used for and crane hook bonded assembly hanger.
Further be, said hanger bracket rides on crossbeam, cooperates for sliding or rolling between the outer wall of two side plates of hanger bracket and the inwall of top board and crossbeam.
Further be between the outer wall of two side plates of said hanger bracket and the inwall of top board and crossbeam the roller that is used to roll and cooperates to be installed.
Further be, on the said hanger bracket motor be installed, on this drive axle of motor driven wheel is installed, this driven wheel is formed rack-and-pinion with the tooth bar engagement that is arranged on the crossbeam.
Further be that the end of said crossbeam side plate is provided with buting iron.
The beneficial effect of the utility model is: this adjustable drop in beam device moves hanger bracket through power plant on crossbeam; Increase the lifting scope of weight-lifting equipment; Do not need the frequent change hanging device for articles in different specifications; Enhance productivity, practice thrift cost, this adjustable drop in beam apparatus structure is simple, easy to operate.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the lateral plan of the utility model.
Among the figure: crossbeam 1, hanger 2, hanger bracket 3, tooth bar 4, roller 5, bearing pin 6, motor 7, driven wheel 8, buting iron 9, side plate 10, top board 11.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Like Fig. 1, shown in Figure 2, hoisting crane is used the drop in beam device, but comprises the crossbeam 1 of level lifting, at least two groups is installed on this crossbeam 1 can drives the hanger bracket 3 that moves along crossbeam 1 length direction by power plant, is equipped with the suspender transom on each hanger bracket 3.On hanger bracket 3, being provided with the suspender transom can be electromagnet, hanger etc.; Transom can adopt mode fixed suspension frame 3 side bottom such as welding, bolted connection; But suspender is stressed when lifting by crane object evenly to be provided with bearing pin 6 in hanger bracket 3 side bottom in order to make, and bearing pin 6 is fixed on suspension 3 side bottom; Transom one end and suspender are fixed, and the other end is wrapped on the bearing pin 6.This drop in beam device moves hanger bracket 3 through power plant on crossbeam 1, increased the lifting scope of weight-lifting equipment, does not need the frequent change hanging device for articles in different specifications.Enhance productivity, practice thrift cost, this adjustable drop in beam apparatus structure is simple, easy to operate.
The hanger 2 that is used to lift by crane on the crossbeam 1 can be symmetricly set on the two ends of crossbeam 1, but in order to protect the service life of steel rope on the weight-lifting equipment, hanger 2 is symmetricly set on the middle part of crossbeam 1 and is positioned at its top.To realize drop in beam device hoisting under the weight-lifting equipment effect.
Extra power for power of reducing friction and whole device; Hanger bracket 3 is better moved on crossbeam 1; Said hanger bracket 3 rides on crossbeam 1; Cooperate for sliding or rolling between the outer wall of two side plates 10 of hanger bracket 3 and the inwall of top board 11 and crossbeam 1, between the outer wall of two side plates 10 of said hanger bracket 3 and the inwall of top board 11 and crossbeam 1 roller 5 that is used to roll and cooperates is installed.Hanger bracket 3 contacts with crossbeam 1 through roller 5.
On the said hanger bracket 3 motor 7 is installed, driven wheel 8 is installed on the transmission shaft of this motor 7, this driven wheel 8 is formed rack-and-pinion with tooth bar 4 engagements that are arranged on the crossbeam 1.Motor is provided with hanger bracket 3 ends, the driven wheel 8 through driven by motor be arranged on that tooth bar 4 on the crossbeam 1 is meshing to move whole hanger bracket 3, and roller 5 is in order to reduce friction and supported and suspended 3 along the rolling of its bearing.
Can not come off when making the spacing of two groups of hanger brackets 3 on crossbeam 1 reach maximum, also be provided with buting iron 9 in the end of crossbeam 1 side plate.When hanger bracket 3 collides buting iron 9, system will cut off the power supply automatically, form protection.Make drop in beam device safety, reliable in use.
In order to make whole drop in beam device two ends balance, also protect steel rope and crossbeam 1 simultaneously, increase steel rope and 1 service life of crossbeam, the hanger bracket 3 of the utility model is under the effect of power plant, and locking phase is to translation.Power plant makes two groups of hanger brackets 3 simultaneously in opposite directions during translation, changes the distance between the suspender on the hanger bracket 3, so just can lift by crane the object of different length.
