Abstract
The invention relates to the technical field of a crawler-type chassis, in particular to a cylinder slideway double-limiting telescopic crawler-type chassis. The cylinder slideway double-limiting telescopic crawler-type chassis comprises a left crawler frame, a left sliding assembly, a right crawler frame, a right sliding assembly, a center rotating frame and hydraulic oil cylinders; the left crawler frame is fixedly connected with the left sliding assembly; the right crawler frame is fixedly connected with the right sliding assembly; the left sliding assembly and the right sliding assembly are respectively connected with the center rotating frame; and the hydraulic oil cylinders are arranged between the center rotating frame and the left crawler frame as well as the right sliding assembly. According to the cylinder slideway double-limiting telescopic crawler-type chassis, the structure is easy to process; when the processing difficulty is reduced, the machining quantity is also reduced; and when the integral cylinder slideway double-limiting telescopic crawler-type chassis works, the crawler frames extend to the greatest extent to increase the earthing width so as to improve the stability of the integral cylinder slideway double-limiting telescopic crawler-type chassis in the working process; when the integral cylinder slideway double-limiting telescopic crawler-type chassis travels and transports, the crawler frames retract to the greatest extent, so that the cylinder slideway double-limiting telescopic crawler-type chassis can pass through a narrow channel, the transportation size of a drilling machine can be reduced and the cylinder slideway double-limiting telescopic crawler-type chassis is easy to use and popularize.
Description
Technical field
The present invention relates to a kind of technical field of caterpillar chassis, the two limit telescopic caterpillar chassiss of especially a kind of cylinder slideway.
Background technology
Flexible caterpillar chassis mainly applies on the equipment such as rotary drilling rig, crawler crane, owing to adopted modular design and realized the function of flexible track frame, and when improving adhesive ability, satisfying stabilization of equipment performance, have convenient transportation, dismounting efficient advantages of higher.Because the track frame of the left and right sides can rely on hydraulic ram to realize the telescopic moving of Width, has greatly widened the operating range of equipment, can adapt to narrow passage and working space, has now progressively obtained being widely used.
Existing flexible caterpillar chassis general structure is rectangular configuration formula slideway normally, and is complicated by the processing technology of analyzing the square-section, the shortcomings such as the large and wearing and tearing of difficulty.Use from complete machine, the rectangular configuration slideway moves, although have grease to increase lubricant effect, because overall mass is large, its contact is also larger, it is large that rigid contact surfaces produces friction force, can cause the permanent wearing and tearing of contact surface in the telescopic process of chassis, make the parallelism difference of rectangle contact surface, can affect the use of equipment when serious, the chassis relies on track frame to lead with the slideway that contacts of base simultaneously, and the impact load before and after bearing is larger.
Summary of the invention
In order to overcome existing flexible caterpillar chassis complex process, machining amount greatly and the deficiency of complete machine poor work stability, the invention provides the two limit telescopic caterpillar chassiss of a kind of cylinder slideway.
The technical solution adopted for the present invention to solve the technical problems is: the two limit telescopic caterpillar chassiss of a kind of cylinder slideway, comprise left track frame, left slide assemblies, right-hand track chiain frame, right slide assemblies, center steering frame and hydraulic ram, left track frame is captiveed joint with left slide assemblies, the right-hand track chiain frame is captiveed joint with right slide assemblies, left slide assemblies is connected with the center steering frame respectively with right slide assemblies, is provided with hydraulic ram between center steering frame and left track frame and the right-hand track chiain frame.
According to another embodiment of the invention, comprise further between center steering frame two ends and left track frame and the right-hand track chiain frame being provided with the slide-and-guide bar that hydraulic ram is provided with the locking bearing pin.
The invention has the beneficial effects as follows that the two limit telescopic caterpillar chassis structures of this cylinder slideway are easily processed, and improve and finish the fabrication properties at member in critical position, when reducing difficulty of processing, also reduced machining amount, when complete machine is worked, track frame has been stretched to greatest extent, increase the ground connection width, thereby the stability when increasing complete machine work when complete machine walking and transportation, shrinks track frame to greatest extent, can and reduce the rig transportation clearance by narrow passage, be easy to use and promote.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1. left track frames among the figure, 2. left slide assemblies, 3. right-hand track chiain frame, 4. right slide assemblies, 5. center steering frame, 6. hydraulic ram, 7. slide-and-guide bar, 8. locking bearing pin.
The specific embodiment
Structural representation of the present invention such as Fig. 1, the two limit telescopic caterpillar chassiss of a kind of cylinder slideway, comprise left track frame 1, left slide assemblies 2, right-hand track chiain frame 3, right slide assemblies 4, center steering frame 5, hydraulic ram 6, slide-and-guide bar 7 and locking bearing pin 8, left track frame 1 is captiveed joint with left slide assemblies 2, right-hand track chiain frame 3 is captiveed joint with right slide assemblies 4, left slide assemblies 2 is connected with center steering frame 5 respectively with right slide assemblies 4, be provided with hydraulic ram 6 between center steering frame 5 and left track frame 1 and the right-hand track chiain frame 3, be provided with slide-and-guide bar 7 between center steering frame 5 two ends and left track frame 1 and the right-hand track chiain frame 3, hydraulic ram 6 is provided with locking bearing pin 8.
During use, left slide assemblies 2 is fixed on respectively on the left track frame 1, right slide assemblies 4 is fixed on respectively on the right-hand track chiain frame 3, left slide assemblies 2 and right slide assemblies 4 are installed with center steering frame 5 respectively and are cooperated slip, the flexible of hydraulic ram 6 can make left track frame 1 and right-hand track chiain frame 3 slidably reciprocate in center steering frame 5 slideways, realize stroke L, in the process of slidably reciprocating, lead and lock that bearing pin 8 is realized the broadening on chassis and spacing when shrinking by slide-and-guide bar 7.The two limit telescopic caterpillar chassis structures of this cylinder slideway are easily processed, improve and finish the fabrication properties at member in critical position, when reducing difficulty of processing, also reduced machining amount, when complete machine is worked, track frame is stretched to greatest extent, increase the ground connection width, thus the stability when increasing complete machine work, when complete machine walking and transportation, track frame is shunk to greatest extent, can and reduce the rig transportation clearance by narrow passage, be easy to use and promote.
