Abstract
A pinion-and-rack type machine frame synchronizing mechanism comprises racks, pinions, a synchronizing shaft, an upper machine frame, guide wheels, bearing supports and support frames, wherein the synchronizing shaft is mounted in the middle of the upper machine frame and is fixed on the upper machine frame through the bearing supports; and the pinions are mounted at the shaft ends and are meshed with the racks on the support frames. When the machine frame rises or falls, the guide wheels guide the machine frame positive, and the pinions and the racks are meshed with each other to enable the machine frame to rise or fall synchronously, so that the machine frame is free from stress.
Description
Technical field
The utility model relates to building mechanical equipment, relates in particular to the polyurethane plate automatic assembly line, the rack-and-pinion open frame lazy-tongs of tracked machine.
Background technology
The lifting of tracked machine upper stand is controlled by hydraulic cylinder, because the asynchronism of a plurality of hydraulic cylinders, upper spider can be subject to twisting force, can cause stand stretch for a long time.
Summary of the invention
The purpose of this utility model provides rack-and-pinion open frame lazy-tongs in order to address the above problem.
The purpose of this utility model is achieved in that rack-and-pinion open frame lazy-tongs, it is comprised of tooth bar, gear, synchronizing shaft, upper spider, directive wheel, bearing block and bracing frame, one synchronizing shaft wherein is installed in the middle of the upper spider, be fixed on the upper spider with bearing block, axle head is installed gear, with the tooth bar engagement on the bracing frame, when the frame lifting, directive wheel correcting frame, gear, tooth bar avoid frame stressed because engagement makes frame keep synchronization lifting.
This applicable novel beneficial effect is: a synchronizing shaft is installed in the middle of frame, is kept when making the frame lifting avoiding distortion synchronously.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Rack-and-pinion open frame lazy-tongs as shown in Figure 1, it is comprised of tooth bar 1, gear 2, synchronizing shaft 3, upper spider 4, directive wheel 5, bearing block 6 and bracing frame 7, wherein in the middle of the upper spider 4 synchronizing shaft 3 is installed, be fixed on the upper spider 4 with bearing block 6, axle head is installed gear 1, with tooth bar 1 engagement on the bracing frame 4, when the frame lifting, directive wheel 5 correcting frames, gear 2, tooth bar 1 avoid frame stressed because engagement makes frame keep synchronization lifting.
Claims (1)
1. rack-and-pinion open frame lazy-tongs, it is characterized in that: it is comprised of tooth bar, gear, synchronizing shaft, upper spider, directive wheel, bearing block and bracing frame, one synchronizing shaft wherein is installed in the middle of the upper spider, be fixed on the upper spider with bearing block, axle head is installed gear, with the tooth bar engagement on the bracing frame, when the frame lifting, directive wheel correcting frame, gear, tooth bar are because engagement makes frame keep synchronization lifting.
