Technical field
The utility model relates to suspender, more particularly, relates to a kind of profile of tooth transmission telescoping mechanism of suspender.
Background technology
The front swing-machine suspender major part that extensively adopts at present is single box-beam structure form; The telescopic drive mode of using is roller chain drives or Driven by Hydraulic Cylinder; Reach more than 3 meters owing to forced stroke during Driven by Hydraulic Cylinder; Cause the hydraulic actuating cylinder manufacture difficulty big, cost is higher, and needs in operation process comparatively that the failure-free supplemental support prevents the stressed unstability in hydraulic actuating cylinder elongation back.Roller chain drives is commonly used in two box-beam structure form suspenders, because roller beam pitch is longer, causes the sprocket wheel reference diameter bigger when being applied in single box-beam structure form suspender, can't in the telescopic girder casing, arrange telescoping mechanism.
The utility model content
The utility model is intended to propose a kind of profile of tooth transmission telescoping mechanism of suspender, to solve the problem that exists in the prior art.
According to the utility model, a kind of profile of tooth transmission telescoping mechanism of suspender is proposed, comprise HM Hydraulic Motor, sprocket wheel, silent chain and link span.HM Hydraulic Motor is fixed on the telescopic girder of suspender, and sprocket wheel is connected to hydraulic motor output shaft, and the toothed surfaces of silent chain is centered around on the sprocket wheel, and link span is fixed on the telescopic girder, and silent chain is connected to link span through connecting screw rod.Wherein fluid motor-driven sprocket wheel rotation, sprocket wheel drives silent chain and does straight-line motion, and silent chain drives telescopic girder through connecting screw rod and link span and does straight-line motion.
In one embodiment, this profile of tooth transmission telescoping mechanism also comprises the induction limiting device, and the induction limiting device is installed in an end of telescopic girder, the position of induction limiting device induction telescopic girder.
In one embodiment, on connecting screw rod, be placed with disk spring, the impact that produces when moving to cushion.
The profile of tooth transmission telescoping mechanism that adopts the utility model by two at a slow speed high-torque hydraulic motor move output torque simultaneously; Drive two sprocket rotation; Chain wheel drive profile of tooth chain is done straight-line motion, makes the translation fore and aft motion thereby drive telescopic girder, and flexible displaced position is through the spacing judgement of induction.Silent chain and telescopic girder framing member junction are equipped with the disk spring that pad adds, and are used for cushioning the impact in the working process.Silent chain is because pitch is less, and it is little that the sprocket wheel reference circle of driving can be done, can be conveniently in suspender telescopic girder cavity arrangements.

The specific embodiment
The utility model has disclosed a kind of profile of tooth transmission telescoping mechanism of suspender, comprises HM Hydraulic Motor, sprocket wheel, silent chain and link span.HM Hydraulic Motor is fixed on the telescopic girder of suspender, and sprocket wheel is connected to hydraulic motor output shaft, and the toothed surfaces of silent chain is centered around on the sprocket wheel, and link span is fixed on the telescopic girder, and silent chain is connected to link span through connecting screw rod.On connecting screw rod, be placed with the impact that produces when disk spring moves to cushion.The rotation of fluid motor-driven sprocket wheel, sprocket wheel drives silent chain and does straight-line motion, and silent chain drives telescopic girder through connecting screw rod and link span and does straight-line motion.One induction limiting device is installed in an end of telescopic girder, the position of induction limiting device induction telescopic girder.
With reference to illustrated in figures 1 and 2, disclosed mechanism map according to the profile of tooth transmission telescoping mechanism of the suspender of the embodiment of the utility model.This profile of tooth transmission telescoping mechanism comprises HM Hydraulic Motor, sprocket wheel 107, silent chain, link span 104 and induction limiting device 106.In embodiment illustrated in figures 1 and 2, comprise two HM Hydraulic Motors, the first HM Hydraulic Motor 101a and the second HM Hydraulic Motor 101b are fixedly connected on the telescopic girder respectively.Sprocket wheel 107 is fixedly connected on the output shaft of the first HM Hydraulic Motor 101a, the second HM Hydraulic Motor 101b.With reference to shown in Figure 4, disclosed the detailed structure of sprocket wheel 107.Fig. 4 is an example with the second HM Hydraulic Motor 101b; Sprocket wheel 107 is installed on the output shaft of the second HM Hydraulic Motor 101b; Sprocket wheel 107 further is connected with silent chain, and the rotation of the second HM Hydraulic Motor 101b drives the silent chain motion through sprocket wheel 107, and then realizes the expanding-contracting action of telescopic girder.In embodiment illustrated in figures 1 and 2, adopted two silent chains equally, the first silent chain 102a and the second silent chain 102b, the toothed surfaces of the first silent chain 102a and the second silent chain 102b is centered around on the sprocket wheel 107.The first silent chain 102a, the second silent chain 102b are connected with link span 104 on being fixed on telescopic girder through connecting screw rod 103, on connecting screw rod 103, are placed with some disk springs 105 and are used for being buffered in the impact that produces in the moving process of telescopic girder.Fig. 3 has further disclosed the structure of link span and connecting screw rod.As shown in Figure 3, be example wherein with the first silent chain 102a, the first silent chain 102a is fixed on the link span 104 through connecting screw rod 103 and disk spring 105, and link span 104 is fixed on telescopic girder, realizes being connected of the first silent chain 102a and telescopic girder.
When suspender need carry out expanding-contracting action; The first HM Hydraulic Motor 101a, the second HM Hydraulic Motor 101b that are fixed on the telescopic girder obtain high pressure oil rotation output torque; Sprocket wheel 107 is along with the HM Hydraulic Motor spinning movement; Drive the first silent chain 102a simultaneously, the second silent chain 102b will rotatablely move and be converted into the straight-line motion of the first silent chain 102a, the second silent chain 102b; The first silent chain 102a, the second silent chain 102b further drag the telescopic girder moving linearly through connecting screw rod 103 and link span 104, and judge by induction limiting device 106 whether the telescopic girder action puts in place.
The profile of tooth transmission telescoping mechanism that adopts the utility model by two at a slow speed high-torque hydraulic motor move output torque simultaneously; Drive two sprocket rotation; Chain wheel drive profile of tooth chain is done straight-line motion, makes the translation fore and aft motion thereby drive telescopic girder, and flexible displaced position is through the spacing judgement of induction.Silent chain and telescopic girder framing member junction are equipped with the disk spring that pad adds, and are used for cushioning the impact in the working process.Silent chain is because pitch is less, and it is little that the sprocket wheel reference circle of driving can be done, can be conveniently in suspender telescopic girder cavity arrangements.
