Description
Technical field
The utility model relates to hoisting crane accessory field, is specially a kind of a kind of Jack arm slide plate adjusting device of adjusting crane arm gap.
Background technology
In crane products, due to a variety of causes, between the large arm of arm and two arms, tend to exist gap, influence factor and assembled condition, technique, parts quality and the size etc. of the reason that this gap produces all have relation.And in actual application, this big machinery of hoisting crane is because higher the causing after assembling arm of safety requirements relating to, if there is gap, can only adopt the method for adding pad or wear plate to make up, yet the pad of this interpolation or wear plate conventionally can produce and think because of wearing and tearing in use for some time, the phenomenons such as fracture is damaged, if do not carry out performance accuracy and operating efficiency that replacing can directly have influence on operator, when serious, also easily have influence on construction quality, bury potential safety hazard, if often detect, change and indirectly cause the raising of hoisting crane care and maintenance cost.
Utility model content
The technical matters that the utility model solves is to provide a kind of Jack arm slide plate adjusting device, to solve the shortcoming in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of Jack arm slide plate adjusting device, install at large arm and two arm connection location places at crane arm, the slide plate, adapter plate, the adjustment screw rod that comprise Flexible Connector and two groups of symmetries, wherein, described adjustment screw front end is provided with slide block, on slide plate, be provided with T-shaped groove, the slide block of adjusting screw rod is installed in T-shaped groove, makes to adjust screw rod and can in T-shaped groove, carry out by slide block slippage; And adjust screw front end, be connected with the adapter plate being welded on large arm, and adjustment nut be set for adjusting the axial length between slide plate and adapter plate of screw rod on adapter plate top; And described Flexible Connector comprises three groups of springs, two groups are connected and fixed plate and slide plate in the inner side of adjusting screw rod respectively, and other one group is arranged between two groups of slide plates for connecting two groups of slide plates.
In the utility model, described is single conchoid Compress Spring for being connected and fixed the spring of plate and slide plate.
In the utility model, the spring of two groups of slide plates of described connection is extension spring.
In the utility model, the globoidal structure that described slide block inner side is laminating arm two arms.
Beneficial effect: the utility model technique is simple, easy to process, assembling easily, is guaranteeing in the upper and lower appropriate clearance in left and right, to have guaranteed hoisting crane performance between arm.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Wherein: 1-adapter plate, 2-Compress Spring, the large arm of 3-, 4-adjust screw rod, 5-bis-arms, 6-extension spring, 7-adjustment nut, 8-slide plate.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the preferred embodiment of a kind of Jack arm slide plate adjusting device of Fig. 1, in the present embodiment, slide plate adjusting device is arranged on large arm 3 and the two arm 5 connection location places of crane arm, for adjusting assembly clearance therebetween.
During slide plate adjusting device assembling, be symmetrical installation, each symmetrical cell includes slide plate 8, adapter plate 1, adjusts screw rod 4, wherein, between two symmetrical slide plates 8, by extension spring 6, connect, by the lateral clearance of pulling back between two slide plates 8 of effect assurance of extension spring 6, Compress Spring 2 is connected with slide plate 8 in adapter plate 1 inner side, and adapter plate 1 is fixed on large arm 3 by welding manner, and slide plate 8 is taken and is contained in the outward flange consistent size of two arm 5 outsides and two arms 5 and fits tightly two arm 5 outer rims, on it, be provided with T-shaped groove, the slide block of adjusting screw rod 4 is installed in T-shaped groove and can in T-shaped groove, carries out by slide block slippage, by adjusting the adjustment nut 7 at screw rod 4 tops, adjust the axial length of screw rod 4 between slide plate 8 and adapter plate 1, Compress Spring 2 and 4 combineds action of adjustment screw rod are to compress two slide plates 8 and two arms 5, and by turn, adjust nut 7 and adjust the gap between large arm 3 and two arms 5.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
