Abstract

The invention discloses an assembling and disassembling device for pin shaft connection. The assembling and disassembling device is characterized in that the assembling and disassembling device is composed of a threaded rod and a movable pin shaft, the threaded rod is arranged in a supporting sleeve, the supporting sleeve is provided with a transmission baffle, a positioning baffle and a supporting slideway, the transmission baffle is provided with a transmission nut and a hand wheel, the transmission nut and the threaded rod are matched with each other to constitute a thread moving mechanism, one end of the threaded rod is fixedly connected with the movable pin shaft through a stopping pin, the two ends of the stopping pin are supported by the slideway and are in sliding connection with the slideway, the movable pin shaft is driven by the threaded rod through rotating of the hand wheel to stretch out of or return to the supporting sleeve in the shape of a cantilever, so that assembling or disassembling of the movable pin shaft and a connecting component is achieved. Compared with the prior art, the assembling and disassembling device has the advantages of being simple in structure, convenient to install, flexible in transmission, good in reliability, low in manufacturing and maintenance cost and capable of easily achieving fast assembling or disassembling of the pin shaft through one person by rotating the hand wheel.

Description

The handler that a kind of bearing pin connects
Technical field
The present invention 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.
Summary of the invention
The handler that a kind of bearing pin not enough for prior art and that provide connects is provided, 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 object of the invention 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 present invention 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the present invention and member connection diagram;
Fig. 4 is the present invention and member dismounting schematic diagram.
The specific embodiment
Consult accompanying drawing 1 ~ accompanying drawing 2, the present invention 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 present invention uses 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.
