Abstract
The utility model discloses an assembling and disassembling device for pin shaft connection. The assembling and disassembling device is characterized by comprising a screw rod and a movable pin shaft, wherein the screw rod is arranged in a supporting sleeve, and a driving baffle, a positioning baffle and a supporting slideway are arranged on the supporting sleeve; a driving nut and a hand wheel are arranged on the driving baffle, and the driving nut and the screw are matched to form a thread motion mechanism; one end of the screw rod is fixedly connected with the movable pin shaft by virtue of a stop pin; two ends of the stop pin are supported on the slideway and are slidably connected with the slideway; the movable pin shaft is driven by rotating the hand wheel by virtue of the screw rod so as to extent or retreat back the supporting sleeve in a cantilever manner, thus realizing the assembling and disassembling of the movable pin shaft and a connecting member. Compared with the prior art, the assembling and disassembling device has the advantages of being simple in structure, convenient to assemble, flexible to drive, good in reliability, low in manufacturing and maintenance cost, and capable of easily realizing the fast assembling and disassembling of the pin shaft by virtue of rotating the hand wheel only by one person.
Description
Technical field
The utility model relates to equipment connection part technical field, especially a kind of quick bearing pin handler for heavy engineering machinery.
Background technology
In heavy engineering machinery, bearing pin interconnection technique is widely used, and some bearing pin needs often handling, as jib connection, the connection handling of suspender etc. of crane.Heavy engineering machinery is because service load is large, bearing pin has the advantages that diameter is large, length is long and weight is large, manual operation is more difficult, when general bearing pin handling, need borrowing apparatus lifting or hammer in pin-and-hole, time-consuming effort again, especially use at the bearing pin of suspender and need often handling, the handling of bearing pin are more frequent, use very inconvenient.
Utility model content
The purpose of this utility model is the handler that a kind of bearing pin not enough for prior art and that provide connects, adopt support tube suit active pin shaft and screw drive structure, rotatablely moving of screw rod is converted into the rectilinear motion of active pin shaft, the support tube of retracting when stretching out in the time that bearing pin is worked or not working, realize the quick handling of bearing pin, the bearing pin that is particularly useful for crane arm support or suspender connects use, the bearing pin that preferably resolves heavy engineering machinery connects a difficult problem, makes the convenient and fast connection, free and relaxed of bearing pin and member.
The concrete technical scheme that realizes the utility model object is: the handler that a kind of bearing pin connects, be characterized in that this handler is made up of the screw rod and the active pin shaft that are arranged in stop sleeve, described stop sleeve is provided with transmission baffle plate, positioning baffle and supporting skid rail, transmission baffle plate and positioning baffle are fixedly installed on stop sleeve two ends by screw respectively, and slideway is fixedly installed on axial symmetry on the inwall of stop sleeve both sides; On described transmission baffle plate, be fixed with the transmission nut of handwheel, transmission nut coordinates formation screw thread travel mechanism with screw rod; Described active pin shaft one end is provided with connecting hole; Described screw rod one end socket joint is fixedly connected with active pin shaft by latch in connecting hole, and active pin shaft is stretched out at latch two ends; Described latch two supports on slideway and with slideway for being slidably connected; Described screw rod is stretched out or retraction stop sleeve with cantilever-shaped by the active pin shaft that rotarily drives of handwheel, realizes the handling of active pin shaft and connecting elements.
The utility model compared with prior art has simple in structure, easy for installation, ensuring smooth transmission, improve the operating efficiency that bearing pin is connected with member, good reliability, manufactures, maintenance cost is low, only needs a people to rotate handwheel just easily to realize the quick handling of bearing pin, time saving and energy saving, be especially suitable for the quick handling that crane arm support or suspender bearing pin connect.

Detailed description of the invention
Consult accompanying drawing 1 ~ accompanying drawing 2, the utility model is made up of the screw rod 3 and the active pin shaft 5 that are arranged in stop sleeve 10, described stop sleeve 10 is provided with transmission baffle plate 8, positioning baffle 12 and slideway 13, transmission baffle plate 8 and positioning baffle 12 are fixedly installed on respectively the two ends of stop sleeve 10 by screw 9, slideway 13 is fixedly installed on axial symmetry on the inwall of stop sleeve 10 both sides; On described transmission baffle plate 8, be fixed with the transmission nut 2 of handwheel 1, transmission nut 2 coordinates formation screw thread travel mechanism with screw rod 3; Described active pin shaft 5 one end are provided with connecting hole 15; Described screw rod 3 one end socket joints are fixedly connected with active pin shaft 5 by latch 4 in connecting hole 15, and active pin shaft 5 is stretched out at latch 4 two ends; Described latch 4 two supports are on slideway 13, and latch 4 and slideway 13 are for being slidably connected; Described screw rod 3 is stretched out or retraction stop sleeve 10 with cantilever-shaped by the active pin shaft 5 that rotarily drives of handwheel 1, realizes the handling of active pin shaft 5 and connecting elements.
Consult accompanying drawing 3 ~ accompanying drawing 4, the utility model is to use like this: positioning baffle 12 is fixed on by a screw 9 on the pin-and-hole of the first member 6 one sides, stop sleeve 10 is fixed on by another screw 9 on the pin-and-hole of the first member 6 opposite sides, clockwise or rotate counterclockwise handwheel 1, the screw thread travel mechanism that transmission nut 2 and screw rod 3 form is converted into rotatablely moving of screw rod 3 rectilinear motion of active pin shaft 5, the rectilinear motion that active pin shaft 5 advances or retreats at the interior work of stop sleeve 10 together with screw rod 3, part weight when slideway 13 on stop sleeve 10 inwalls can support movable bearing pin 5 cantilever, only need a people just can make active pin shaft 5 with easy access in the pin-and-hole of the first member 6 by light rotation hand wheel 1, complete being fast connected and dismounting of the first member 6 and second component 7 bearing pins 5, use very convenient.
