Summary of the invention
For overcoming above-mentioned existing shortcoming, the utility model provides a kind of pulley-type inspection shaft lid lifting instrument, and the effect by pulley, connecting rod, manual setter etc. reaches laborsaving purpose easily.
The utility model is realized with following technical scheme: a kind of pulley-type inspection shaft lid lifting instrument, form by base portion, support section and lift portion three parts; Base portion comprises two base support bar I that parallel and base support bar III, and the end of two base support bar I that parallel and base support bar III is connected by perpendicular base support bar II; Support section is made up of the support vertical rod of band boss, rotatable sleeve, retractable supports bar I and the retractable supports bar II that is sleeved in the support vertical rod; The support vertical rod of band boss is fixed on the base support bar II, and rotatable sleeve utilizes boss to be fixed in the support vertical rod of band boss, and retractable supports bar I is connected with retractable supports bar II; Retractable supports bar II and rotatable sleeve are fixed together; Lift portion comprises a movable pulley, two fixed pulleys and shaking winding device; On movable pulley, be fixed with hinge, hinge is connected with the hook that is used to hook well lid, fixed pulley and another fixed pulley are separately fixed on retractable supports bar I and the retractable supports bar II, the shaking winding device is installed in by bracing frame and supports in the vertical rod, is connected by steel rope between each pulley; The two ends of steel rope link to each other with the hand-operated mechanism of hook with the shaking winding device respectively.
The beneficial effects of the utility model are:
1, use hand-operated mechanism and pulley combination can save the power of half at least, so the workman can use this instrument that well lid is opened easily.
2, easy to carry, only need portablely this instrument to be taken to each workyard once personal.
3, adopt rotatable sleeve, the rotation of well lid is moved after can easily realizing promoting.
4, this tool construction is simple, and is easy to make, and cost is low, is convenient to promote.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model master TV structure scheme drawing.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
Fig. 4 is the hand-operated mechanism structural representation.
Among the figure: 1, hook, 2, hinge, 3, movable pulley, 4, steel rope, 5, fixed pulley, 6, retractable supports bar I, 7, another fixed pulley, 8, retractable supports bar II, 9, support vertical rod, 10, rotatable sleeve, 11, bracing frame, 12, the shaking winding device, 13, wind, 14, pin, 15, base support bar I, 16, base support bar II, 17, base support bar III.
The specific embodiment
As shown in Figure 1-Figure 3, base portion is made up of base support bar I 15, base support bar II 16 and base support bar III17.Bolt together between three strut bars of described base portion; Promptly wherein base support bar I15 and base support bar II16 are by bolted connection, and base support bar III17 and base support bar II16 pass through bolted connection.Support section is made up of support vertical rod 9, rotatable sleeve 10 and retractable supports bar I 6, the retractable supports bar II8 of band boss.Wherein adopt the mode of welding to be fixed on the base support bar II16 with the support vertical rod 9 of boss, 10 in rotatable sleeve utilizes boss to be fixed in the support vertical rod 9 of band boss, retractable supports bar I6 and retractable supports bar II8 link together with pin 14, on retractable supports bar II8, have a plurality of pin jacks, utilize pin 14 to insert and realize in the different pin jacks regulating the distance that supports, to adapt to the lifting of different-diameter well lid.Retractable supports bar II8 adopts the mode and the rotatable sleeve 10 of welding to be consolidated.Lift portion is made up of 3 pulleys and hand winding device.One of them pulley is a movable pulley 3, is fixed with hinge 2 on movable pulley 3, and hinge 2 is connected with hook 1, is used to hook well lid.Two other fixed pulley 5 and fixed pulley 7 are separately fixed on retractable supports bar I6 and the retractable supports bar II8.As shown in Figure 4, wind 13 is arranged on the shaking winding device 12, wind 13 connects to form the hand-operated mechanism with auto-lock function by axle and winding device, shaking winding device 12 is fixed on the bracing frame 11, bracing frame 11 is connected with the support vertical rod 9 of band boss, is connected by steel rope 4 between each pulley.
During use, utilization is fixed on the hook 1 on the movable pulley 3, hook well lid, with the hand rocking handle 13 of starting, wind rotates and drives winding device 12 rotations, the rotation of winding device 12, rolling of steel rope 4 will be driven, rolling of steel rope 4 with drive movable pulley 3 upward movements, thus drive hook 1 upward movement, and the upward movement of hook 1 then makes well lid be raised.After well lid promoted, wind 13 had self-locking mechanism, was lifted in the air to keep well lid.At this moment, can rotate retractable supports bar I6 and retractable supports bar II8 around supporting vertical rod 9 rotations, well lid is left the well lid mouth, make things convenient for the workman to construct, well lid leaves the self-locking mechanism that can put down wind 13 behind the well head well lid is put in ground.After workman construction finishes, can again well lid be mentioned, rotate to reduce behind the pithead position and be put back into the home position.
