The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, this long handle gripping apparatus mainly comprises handle 1, sleeve 2, the gripping apparatus bar that is made up of connecting rod bottom joint 6, spring washer 7, pin with split pin hole 11, connecting rod top joint 12, bolt 15 and the gripping apparatus head that is made up of housing 8, movement parts 9, handgrip 10, cylinder 16, alignment pin 19 etc.Handle 1 and sleeve 2 interference fit; One end of connecting rod top joint 12 passes sleeve 2 and is fixedly connected through pin with split pin hole 11 with handle 1; One end of the other end of connecting rod top joint 12 segmentum intercalaris 14 in the connecting rod snap joint 4 of draw-in groove 5 through band cylindrical pins 3 and spring 13 and connecting rod joins; The other end of segmentum intercalaris 14 also is to be connected with connecting rod bottom joint 6 through the connecting rod snap joint 4 of draw-in groove 5 through band cylindrical pins 3 and spring 13 in the connecting rod; Cylinder 16 is contained in the housing 8, and cylinder 16, connecting rod bottom joint 6, housing 8 threes are fixed together with bolt 15, screw 17.Two through holes (not providing label among the figure) that 6 belows are saved in the connecting rod bottom are the water in the emptying gripping apparatus bar when being used in water, promoting checkout equipment.Two openings (not marking among the figure) of housing 8 belows symmetry are the tracheaes that is used to draw cylinder 16, are convenient to be threaded the piston rod of cylinder 16 with movement parts 9, moreover are convenient to observe moving of movement parts 9.Handgrip 10 is fixed on the housing 8 through screw 17, nut 18, and handgrip 10 can be around screw 17 rotation, simultaneously alignment pin 19 be used for checkout gear on pin-and-hole match, thereby handgrip 10 is positioned.
Like Fig. 2, shown in Figure 3; The gripping apparatus bar is the structure that adopts merogenesis; Can be segmentum intercalaris 14 in connecting rod top joint 12, the connecting rod, connecting rod bottom joint 6 according to the different of form and present position, be processed with the draw-in groove 5 that is connected with connecting rod snap joint 4 with cylindrical pins 3 and spring 13 on each connecting rod joint respectively, two ends extrusion spring 13 compressed, rotates when the gripping apparatus bar connected; Connect the back and discharge, rely on the elastic force of spring 13 to play connection and fixation.Because the gripping apparatus bar is to adopt the merogenesis structure, so the length of gripping apparatus bar can change according to the usage quantity of segmentum intercalaris in the connecting rod 14.Like the gripping apparatus pole length is 1 meter 20 centimetres, and then three of connecting rod joints are respectively 40 centimetres, if the gripping apparatus pole length needs 2 meters words then to need only segmentum intercalaris 14 in the connecting rod that increases by 80 centimetres at a joint.Owing to be processed with draw-in groove 5 respectively on each connecting rod joint, be to be connected behind the connecting rod snap joint 4 embedding draw-in grooves 5 through band cylindrical pins 3 and spring 13 to fix between joint and the joint.
As shown in Figure 4, during handgrip 10 work, cylinder 16 drives movement parts 9 and moves up and down, open with closed thereby drive handgrip 10, the inner wall limits of housing 8 rotation amplitude of handgrip 10.The design of gripping apparatus head adopt ' lost efficacy---safety " operation principle, when losing source of the gas, the piston rod of cylinder 16 moves downward with movement parts 9 dependence gravity, impels handgrip 10 to open, and catches checkout equipment.
The operating procedure of the long handle gripping apparatus that the utility model provides is following:
1, by connection gripping apparatus head shown in Figure 4 and to check whether each parts has loosening.
2, connect source of the gas, whether inspection handgrip 10 can normal running.
3, confirm the quantity of segmentum intercalaris 14 and connecting rod snap joint 4 in the connecting rod according to the operating platform height, press Fig. 2 fastening means bar.
4, connect whole gripping apparatus by Fig. 1.
5, the gripping apparatus of slinging and assembling is suppressed, and movement parts 9 moves downward and promotes promptly checkout gear of handgrip 10.
6, the operation crane places preposition to checkout gear, and cylinder 16 is oppositely suppressed, and handgrip 10 closures discharge checkout equipment.
7, remove the long handle gripping apparatus.
