Abstract

The utility model discloses a special stand for movable pulley overhauls, it includes crane steel wire rope, and crane steel wire rope passes the wire rope hole of setting on the movable pulley, and the bottom welding of movable pulley has the lug board, is connected with on the lug board and hangs the head, and the movable pulley is placed on overhauing the support, overhauing the support and including the base, the welding has four stands on the base, and two preceding, back side welding that the stand constitutes have the crossbeam, and two left and right side welding that the stand constitutes there is the longeron, and the welding has many cross arrangement's stiffener between crossbeam and base, and the welding has many slope cross arrangement's a bracket pole between stand and crossbeam, and the left and right both sides face bonding on the stand top has the ejector pin. Support the movable pulley head through what this overhauld that support can be convenient, make it in that to overhaul the in -process atress even, avoid traditional maintenance method can hang the damage of head, improve the efficiency of overhauing.

Description

A kind of special stand for movable pulley maintenance
Technical field
The utility model relates to a kind of maintenance holder device, particularly relates to a kind of special stand for movable pulley maintenance.
Background technique
The lifting mechanism of the hoists such as travelling crane, Gantry crane, platform hoist drags sheave block by wire rope and realizes weight lifting, part crane hoisting weight is large, use is frequent, for ensureing that its movable pulley normally runs, need regularly to check crane pulley group, safeguard.When running block occur comparatively major break down time, also need to disintegrate to check each movable pulley and bearing damage situation to running block, and change in time.There is following shortcoming in present stage crane pulley maintenance:
1, running block and shackle plate link together composition hoist hang head, when hang head drop to ground overhaul time, shackle plate first lands, whole weight of hanging head concentrates on shackle plate, when the repair time is longer, easily cause shackle plate to be out of shape, affect the normal use of hoist.
2, running block decompose maintenance time, hang head and need keep flat ground, cause have all the time one side be pressed in below, the links such as operating space is restricted, part bolt are not quick detachable, waste time and energy, are unfavorable for carrying out of service work.
3, running block vertically or when lying in ground, wire rope is all in stress, causes and hang head instability, easily rock, bring hidden danger to the safety of maintainer.
Model utility content
The purpose of this utility model is to provide a kind of special stand for movable pulley maintenance, can be supported movable pulley head easily by this maintenance support, make its uniform force in maintenance process, avoid the damage of traditional repair method head capable of hoisting, improve the efficiency of maintenance.
In order to realize above-mentioned technical characteristics, the technical solution adopted in the utility model is: a kind of special stand for movable pulley maintenance, it comprises crane rope, crane rope is through the wire rope hole be arranged on movable pulley, the bottom welding of movable pulley has shackle plate, shackle plate is connected with and hangs head, movable pulley is positioned on maintenance support, described maintenance support comprises base, base is welded with four root posts, before column is formed, latter two side is welded with crossbeam, the left side that column is formed, right two sides are welded with longeron, the reinforcing bar of many intercross arrangement is welded with between crossbeam and base, the carrier bar of many inclination intercross arrangement is welded with between column and crossbeam, on the left side on column top, right bi-side are welded with push rod.
Form " V " type bracket after described carrier bar welding to match with the external frame of movable pulley.
Described maintenance support all adopts angle steel material to be welded.
The utility model has following beneficial effect:
When overhauling, immediately below this stentplacement can being hung under movable pulley, then can be vertical movable pulley is positioned in " V " type carrier bar of support, thus movable pulley is played a supporting role, effectively can avoid shackle plate by above-mentioned structure and hang the harm that head deforms because bearing weight.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the maintenance process schematic diagram of special stand of the present utility model.
Fig. 2 is the plan view of special stand of the present utility model.
Fig. 3 is the left view of special stand of the present utility model.
In figure: crane rope 1, wire rope hole 2, movable pulley 3, shackle plate 4, hang 5, push rod 6, column 7, longeron 8, base 9, carrier bar 10, crossbeam 11, reinforcing bar 12.
Embodiment
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further.
As Figure 1-3, a kind of special stand for movable pulley maintenance, it comprises crane rope 1, crane rope 1 is through the wire rope hole 2 be arranged on movable pulley 3, the bottom welding of movable pulley 3 has shackle plate 4, shackle plate 4 is connected with and hangs 5, movable pulley 3 is positioned on maintenance support, described maintenance support comprises base 9, base 9 is welded with four root posts 7, before column 7 is formed, latter two side is welded with crossbeam 11, the left side that column 7 is formed, right two sides are welded with longeron 8, the reinforcing bar 12 of many intercross arrangement is welded with between crossbeam 11 and base 9, the carrier bar 10 of many inclination intercross arrangement is welded with between column 7 and crossbeam 11, on the left side on column 7 top, right bi-side are welded with push rod 6.
Further, form " V " type bracket after described carrier bar 10 welding to match with the external frame of movable pulley 3.Conveniently can be matched with the cylindrical of movable pulley 3 by " V " type structure, thus be held up, ensure that and the stability that movable pulley 3 supports ensure that the Security of maintenance process.
Further, described maintenance support all adopts angle steel material to be welded.Adopt the angle steel material of frame type to make the structure of whole support more simple, weight is lighter, thus facilitates the movement of support.
When carrying out crane pulley maintenance by this patent, tool has the following advantages:
1, movable pulley vertically drops on support, and shackle plate and other positions of sheave block do not come in contact with ground, uniform force, and avoid shackle plate and movable pulley outer cover to deform, reliability is high.
2, this special stand is tower structure, and movable pulley drops down onto after on support, and all there are enough inspection operation spaces at each position, and be convenient to dismounting and reassemble, operability is good.
3, the position of special stand between two shackle plates supports, and does not affect the maintenance of decomposition step by step of movable pulley and shackle plate.
4, movable pulley support fixing after, wire rope is in free hang, to hanging head and support does not have draw power, avoids support to rock, good stability.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
