Description

Hoist track pulley

The utility model relates to the Hoist track pulley of a kind of handling rail or railway frog, belongs to a kind of railway hoist tool.

Existing Hoist track pulley mainly is made up of joystick, bracing frame, U type hook, hanger rail pincers and walking wheel, and each component part is welded as a whole; This Hoist track pulley is according to lever principle handling rail, owing to be subjected to the restriction of factors such as track clearance on the railway, stick design can't be got very long, therefore, the railway worker needs just can finish work such as lifting, balance with very big strength in the process of handling rail, the operation effort; And, use very inconvenient because each component part relative fixed is difficult for adjusting in operating process; Outside adding, because it is shorter to be provided with an end arm of force of hanger rail pincers, this Hoist track pulley can't handling has the railway frog of certain width.

The purpose of this utility model be to overcome above-mentioned weak point of the prior art and a kind of rapid operation is provided, use flexible, easy to adjust, but but the not only Hoist track pulley of handling rail but also handling railway frog, thereby alleviate railway worker's labour intensity, and improve the result of use of Hoist track pulley.

Hoist track pulley provided by the utility model, have joystick (1), suspension rod (2), U type hook (3), iron chains hook (4), jaw (5), support underframe (6) and walking wheel (7), main points of the present utility model are to support underframe (6) to be provided with bolster (10), bolster (10) is provided with an opening rotating cylinder (11), and joystick (1) and suspension rod (2) are separately fixed on the opening rotating cylinder (11).

Have one between joystick of the present utility model (1) and the suspension rod (2) less than 180 ° angle, be provided with one between joystick (1), suspension rod (2) and the opening rotating cylinder (11) and reinforce pull bar (18).

Suspension rod of the present utility model (2) is provided with a slide block (8), one block (12) is arranged on the slide block (8), suspension rod (2) is gone up and the bottom of slide block (8) has several fixed pin holes (14), and slide block (8) is positioned on the suspension rod (2) by set pin (13); U type hook (3) is provided with one can go up the scroll wheel (9) that rolls at slide block (8).

Jaw of the present utility model (5) two ends respectively are provided with a through hole (17,19), and the major part of jaw (5) is provided with the prong (20) that can clamp the web of the rail.

The relevant position of joystick of the present utility model (1) and support underframe (6) is provided with a hasp (16).

Following accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is the axonometric drawing of the utility model embodiment.

Fig. 2 is the structural representation of the utility model embodiment.

Fig. 3 is the B-B cutaway view of the utility model embodiment.

Fig. 4 is the C-C view of the utility model embodiment.

Below in conjunction with embodiment (accompanying drawing) the utility model is described in further detail.

With reference to accompanying drawing, Hoist track pulley of the present utility model has joystick (1), suspension rod (2), U type hook (3), iron chains hook (4), jaw (5), support underframe (6) and walking wheel (7), support underframe (6) and be provided with a pivot shaft (10), one opening rotating cylinder (11) is arranged on the bolster, joystick (1) and suspension rod (2) are welded on respectively on the opening rotating cylinder (11), have one between joystick (1) and the suspension rod (2) less than 180 ° angle, end at suspension rod (2), be welded with one on the joystick (1) and on the opening rotating cylinder (11) and reinforce pull bar (18), on the relevant position of joystick (1) and support underframe (6), also be welded with a hasp (16), one slide block (8) is arranged on the suspension rod (2), one block (12) is arranged on the slide block (8), the bottom of slide block (8) is wedge shape, bottom at slide block (8) has through hole, have eight fixed pin holes (14) on the suspension rod (2), also have a groove (15) on the suspension rod (2), the bottom of slide block (8) is contained in the groove (15), and by set pin (13) location; The position of slide block (8) can pass through set pin (13) as required and fixed pin holes (14) is adjusted; One scroll wheel (9) is arranged on the U type hook, scroll wheel (9) can be gone up rolling at slide block (8) and suspension rod (2), iron chains hook (4) hangs on the U type hook (3), iron chains hook (4) passes the through hole (17) of jaw (5) one ends, and the other end of jaw (5) is provided with a prong (20) and the through hole (19) that can clamp the web of the rail; When handling rail or railway frog, only need prong (20) is clamped the web of the rail, pass through through hole (19) then, utilize the rigidity of jaw and rail or railway frog to lift by crane jaw (5) and rail or railway frog bolt up.

Owing to adopted slide block (8) on the suspension rod (2) in the utility model, slide block (8) can be adjusted by set pin (13) as required, and on U type hook (3), be provided with scroll wheel (9), in the process of hanging rail or railway frog, scroll wheel (9) can be gone up rolling at slide block (8) or suspension rod (2), when the operator when an end of joystick (1) is afterburning, slide block (8) tilts to the inside, scroll wheel (9) then rolls to the inside, drive rail simultaneously or railway frog moves inward, the arm of force is shortened gradually, thereby the moment that the deadweight of rail or railway frog is produced reduces gradually, according to lever principle, the operator is used for handling, the strength of balance just can progressively reduce.Angle between joystick (1) and the suspension rod (2) is arranged to less than 180 °, the ranging coverage of joystick (1) is shortened.On pivot shaft (10), be provided with opening rotating cylinder (11), actuating element gone up at bolster (10) rotated flexibly.In addition, jaw of the present utility model (5) is avoided bumping with Hoist track pulley after can making the railway frog lifting, improves the work effect of Hoist track pulley.So this is dashed forward and compares with novel and existing Hoist track pulley, have rapid operation, use advantage flexible, easy to adjust.
