Abstract
The utility model relates to a pin shaft screw type self dissembling device of a caterpillar crane, which belongs to the pin shaft screw type self dissembling device of the caterpillar crane. The self dissembling device is composed of a pin shaft, a bracket, a threaded rod and a thread frame. One end of the pin shaft is provided with a 'C'-shaped groove. One end of the bracket is installed on a line rack in the vicinity of the pin shaft, and the other end is provided with the thread frame. Thread holes are installed on the thread frame. One end of the threaded rod is installed on the thread frame and is provided with a screw nut, and the other end is provided with a lug boss. The lug boss is positioned in the 'C'-shaped groove of the pin shaft. The utility model has the advantages that the disassembly and the assembly of the pin shaft can be realized by driving the pin shaft through the threaded rod which is screwed out and screwed in, the utility model has the function of preventing the pin shaft from shedding, a support plate at the bottom can support the extraction part of the pin shaft to prevent the pin shaft from shedding, the pin shaft does not need to be extracted for additional placement at the time of transportation, space can be saved, carrying is convenient, operation is simple and fast, the connection, the disassembly and the assembly of the pin shaft can be shortened, the structure is simple, the cost is lower, the external connection power is not needed and time and labour can be saved.
Description
Technical field
The utility model relates to a kind of stripping assembly of crawler crane bearing pin, and particularly a kind of crawler crane bearing pin screw-type is from dismantling device.
Background technology
At present, the pin type that is connected between a lot of large-sized structural parts of the crawler crane of domestic production connects, the dismounting of bearing pin is manual dismounting or hydraulic dismounting, when adopting manual dismounting, because bearing pin is bigger, the difficulty of manual dismounting is also bigger, and needs external power when adopting hydraulic dismounting, and need Hydraulic Elements, cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of dismounting simply, not need the low crawler crane bearing pin screw-type of external power, cost from dismantling device.
The purpose of this utility model is achieved in that this is made of bearing pin, carriage, thread rod and threaded frame from dismantling device, and an end of bearing pin has one " C " shape groove; One end of carriage is installed on the bearing pin capable frame on every side, and threaded frame is installed on the other end, and tapped bore is arranged on the threaded frame; Thread rod one end is installed on the threaded frame and a nut is arranged, and the other end has a boss, and boss is positioned at " C " shape groove of bearing pin.
Beneficial effect: owing to adopt such scheme, the assembly and disassembly of bearing pin are to realize with back-out by the screw-in of thread rod, when bearing pin is dismantled, bearing pin is extracted by drive by the thread rod that screws out, carriage is held bearing pin, prevent that bearing pin from coming off, when bearing pin was packed into, bearing pin was pressed into axis hole by the thread rod that screws in.Dismounting simply, does not need external power, cost low, has reached the purpose of this utility model.Advantage: 1, solved large-tonnage crawler crane large component and connected the difficult problem of bearing pin stack-mounted dismounting, driven dismounting and the assembling that bearing pin just can be realized bearing pin by screwing out the thread rod that screws in.2, have the bearing pin of the preventing function that comes off, bottom bracket can be held bearing pin and be extracted part, prevents that bearing pin from coming off, and bearing pin needn't be extracted in addition and put when transportation, saves the space, is convenient to delivery.3, simple and efficient to handle, shortened dismounting of connection bearing pin and stack-mounted time greatly.4, simple in structure, cost is low, does not need external power, and save time, laborsaving.
