Description
Technical field
The present invention relates to a kind of lowering or hoisting gear, be particularly well-suited on cold press use.
Background technology
Existing cold press oil hydraulic system typically configures 4 sets or 6 set hydraulic cylinders, it is achieved lift the lifting and compression motion presented a theatrical performance as the last item on a programme.Lifting present a theatrical performance as the last item on a programme when doing lifting action, caused by hydraulic cylinder sealing body difference, hydraulic cylinder lifting resistance inconsistent, easily cause hydraulic cylinder rising or falling speed inconsistent, cause lifting present a theatrical performance as the last item on a programme generation tilt the most stuck, equipment operational reliability is poor.
Summary of the invention
The task of the present invention is to provide a kind of cold press synchronization lifting, is effectively increased one and the cold press synchronous lifting device of equipment reliability of operation.
The task of the present invention so completes, one and cold press synchronous lifting device, it is characterized in that: longitudinal synchronization lifting uses pinion and-rack symmetrical configuration to be arranged on the two ends that lifting is presented a theatrical performance as the last item on a programme, the symmetrical each installation in the two ends, bottom that lifting is presented a theatrical performance as the last item on a programme one synchronizes tooth bar, it is provided with and the synchromesh gear of tooth bar engagement rotation on the press frame of the bottom that lifting is presented a theatrical performance as the last item on a programme, synchronous cross lifting uses sprocket chain strip structure, it is symmetrically mounted on the two ends at the top of upper holder, the upper holder two ends at the top of press frame respectively arrange a set of synchronous sprocket wheel, described synchronous sprocket wheel is fixed on the press frame of upper holder by bearing, described lifting two ends both lateral sides of presenting a theatrical performance as the last item on a programme is provided with chain mounting bracket, the two ends of synchronization chain are fixed on chain mounting bracket by chain tension bar, connected by chain between lower sprocket and the synchronous sprocket wheel on top.Gear is installed in the two ends of major axis, and to be fixed on press frame realization by bearing synchronization with tooth bar.
The present invention has the effect that the technical program simple in construction, the synchronous lifting device of vertical and horizontal can ensure that lifting present a theatrical performance as the last item on a programme keeping parallelism lifting, be effectively improved the reliability of equipment.

Drawing illustrates: 1, press frame, 2, hydraulic cylinder, 3, synchromesh gear, 4, lower sprocket, 5, synchronize tooth bar, 6, tensioning coupling bar, 7, chain mounting bracket, 8, lifting present a theatrical performance as the last item on a programme, 9, synchronization chain, 10, upper holder, 11, synchronous sprocket wheel.
Detailed description of the invention:
The technical program is lifting the synchronization tooth bar of longitudinal both sides of presenting a theatrical performance as the last item on a programme under the restriction of synchromesh gear, rising or falling speed and lifting position are always consistent, thus realize lifting the longitudinal synchronization lifting presented a theatrical performance as the last item on a programme, the synchronous sprocket wheel at press frame two ends limits transverse ends synchronization chain respectively and keeps synchronization lifting, thus realizes lifting the synchronous cross lifting presented a theatrical performance as the last item on a programme.
Specific embodiment is as shown in Figure 1, longitudinal synchronization lifting uses pinion and-rack symmetrical configuration to be arranged on the two ends that lifting is presented a theatrical performance as the last item on a programme, lifting present a theatrical performance as the last item on a programme 8 two ends, bottom be symmetrically installed one synchronize tooth bar 5, be provided with the synchromesh gear 3 with tooth bar engagement rotation, furtherly on the press frame 1 of bottom that lifting is presented a theatrical performance as the last item on a programme: gear 3 be installed in the two ends of major axis be fixed on press frame 1 by bearing realize synchronization with tooth bar；When lifting present a theatrical performance as the last item on a programme 8 carry out lifting action time, be installed on lifting present a theatrical performance as the last item on a programme 8 longitudinal both sides the restriction synchronizing the synchromesh gear 3 that tooth bar assembles at major axis two ends under, reach rising or falling speed and lifting position be always consistent, thus realize lifting present a theatrical performance as the last item on a programme 8 longitudinal synchronization lifting.
nullSynchronous cross lifting uses sprocket chain strip structure，It is symmetrically mounted on the two ends at the top of upper holder 10，As depicted in figs. 1 and 2，Upper holder 10 two ends at the top of press frame 1 respectively arrange a set of synchronous sprocket wheel 11，Described synchronous sprocket wheel is fixed on the press frame 1 of upper holder by bearing，Furtherly: the structure of sprocket wheel includes horizontal major axis and the sprocket wheel being installed on major axis two ends and bearing，Described lifting two ends both lateral sides of presenting a theatrical performance as the last item on a programme is provided with chain mounting bracket 7，The two ends of synchronization chain 9 are fixed on chain mounting bracket 7 by chain tension bar 6，Connected by chain 9 between the synchronous sprocket wheel 11 on lower sprocket 4 and top，Described chain tension coupling bar 6 is to adjust synchronization chain 9 and the chain syn-chro-step of the other end and the amount of tension of chain，When lifting present a theatrical performance as the last item on a programme 8 carry out lifting action time，Lifting is presented a theatrical performance as the last item on a programme 8 drive chains 9 drive synchronous sprocket wheel 11 to rotate，The synchronization chain 9 being limited transverse ends by synchronous sprocket wheel respectively keeps synchronization lifting，Thus realize lifting the synchronous cross lifting presented a theatrical performance as the last item on a programme.
The hydraulic cylinder 2 that the lifting that lifting on cold press is presented a theatrical performance as the last item on a programme is dependent on installing below completes.The synchronous lifting device that cold press portraitlandscape described above is arranged, it is ensured that lift keeping parallelism lifting of presenting a theatrical performance as the last item on a programme, be effectively improved equipment reliability of operation.
