Abstract
The utility model relates to a gantry lifting device assembly. The gantry lifting device assembly comprises an upper supporting rod, a lower supporting rod and two connecting assemblies used for being connected with the upper supporting rod and the lower supporting rod. Each connecting assembly is composed of a plurality of first connecting plates and a plurality of second connecting plates, wherein the length of each first connecting plate is different from that of each second connecting plate, and the first connecting plates and the second connecting plates are connected in sequence in an intersecting mode through spring pins and locating pins and form a quadrangle structure which an retract and stretch vertically. Lifting plate connecting pins are additionally arranged on the portions, located in the middle of the gantry lifting device assembly, of the two connecting assemblies, and connecting rib plates are arranged between the lifting plate connecting pins so that the lifting plate connecting pins which are connected with the connecting rib plates can move synchronously. In the use process of the gantry lifting device assembly, vertical adjustment is achieved through the quadrangle structures which are composed of the connecting plates and can retract and stretch vertically. The gantry lifting device assembly of the structure is more convenient and safe to use, thereby improving the use efficiency of a forklift; due to the arranged connecting rib plates, it can be guaranteed that the lifting plate connecting pins are evenly stressed and work simultaneously, and it is also guaranteed that the connecting assemblies located on the two sides conduct synchronous movement.
Description
Technical field
The utility model relates to a kind of portal-framed structure, be with being specifically related to a kind of be applied on fork truck door frame lifting assembly.
Background technology
Fork truck is being specifically applied in the process of producing assembling, and its door frame is too high should not use suspender belt, so easily produces danger and inconvenient user's practical operation.
Utility model content
The utility model object be provide in order to overcome the deficiencies in the prior art a kind of be applied on fork truck door frame lifting assembly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of door frame lifting assembly, comprise strut, lower supporting rod and for connecting two groups of coupling assemblings of upper and lower strut, described coupling assembling is arranged on the left and right sides of strut and lower supporting rod symmetrically; The first connecting panel and the second connecting panel that described coupling assembling is differed by multiple length respectively again form, and described the first connecting panel and the second connecting panel be by resilient pin and locating dowel pin cross connection successively, and the quadrilateral structure that composition can be flexible up and down; This door frame lifting assembly is also equipped with boatswain chair connecting pin on two groups of coupling assemblings that are positioned at middle part, and connection gusset is set between it, so that coupled boatswain chair connecting pin is synchronized with the movement.
Further, described resilient pin is horizontally through the contact part of the first connecting panel and the second connecting panel, and the pin that is positioned in its end is spacing firmly; The end of described resilient pin is also set with plain cushion, and described plain cushion is arranged on the inner side of locating dowel pin.
Further, on the contact site that described the first connecting panel is connected at it with the second connecting panel, be also provided with copper sheathing.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Door frame lifting assembly described in the utility model is in the concrete process using, the left and right sides of upper strut is placed on respectively in the channel-section steel of door frame left and right, then utilize formed by connecting panel below it can be flexible up and down quadrilateral structure carry out up-down adjustment, the door frame lifting assembly of this structure uses more convenient, safety, and then has improved the service efficiency of fork truck; The connection gusset being simultaneously provided with can guarantee that boatswain chair connecting pin is stressed even, works simultaneously, and then guarantees that the coupling assembling of both sides is synchronized with the movement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the front view of door frame lifting assembly described in the utility model;
Accompanying drawing 2 is the A portion enlarged drawing of accompanying drawing 1;
Accompanying drawing 3 is the quadrilateral structure being made up of the first connecting panel and the second connecting panel in door frame lifting assembly described in the utility model;
Wherein: 1, upper strut; 2, lower supporting rod; 3, coupling assembling; 4, the first connecting panel; 5, the second connecting panel; 6, resilient pin; 7, locating dowel pin; 8, boatswain chair connecting pin; 9, connect gusset; 10, plain cushion; 11, copper sheathing.
the specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-3 is a kind of door frame lifting assembly described in the utility model, comprises strut 1, lower supporting rod 2 and for connecting two groups of coupling assemblings 3 of upper and lower strut, described coupling assembling 3 is arranged on the left and right sides of strut 1 and lower supporting rod 2 symmetrically; The first connecting panel 4 and the second connecting panel 5 that described coupling assembling 3 is differed by multiple length respectively again form, and described the first connecting panel 4 and the second connecting panel 5 be by resilient pin 6 and locating dowel pin 7 cross connection successively, and the quadrilateral structure that composition can be flexible up and down; This door frame lifting assembly is also equipped with boatswain chair connecting pin 8 on two groups of coupling assemblings 3 that are positioned at middle part, and connection gusset 9 is set between it, so that coupled boatswain chair connecting pin 8 is synchronized with the movement.
Wherein said resilient pin 6 is horizontally through the contact part of the first connecting panel 4 and the second connecting panel 5, and the pin 7 that is positioned in its end is spacing firmly; The end of described resilient pin 6 is also set with plain cushion 10, and described plain cushion 10 is arranged on the inner side of locating dowel pin 7; On the contact site that described the first connecting panel 4 is connected at it with the second connecting panel 5, be also provided with copper sheathing 11.
Door frame lifting assembly described in the utility model is in the time of concrete use, take the quantity of the scalability quadrilateral structure that formed by the first connecting panel 4 and the second connecting panel 5 be 3 as one group, boatswain chair connecting pin 8 be set and be connected gusset 9, so just can guarantee that two groups of set left and right coupling assembling 3 is synchronized with the movement.It is in the concrete process using, the left and right sides of upper strut 1 is placed on respectively in the channel-section steel (not shown) of door frame left and right, then utilize formed by connecting panel below it can be flexible up and down quadrilateral structure carry out up-down adjustment, the door frame lifting assembly of this structure uses more convenient, safety, and then has improved the service efficiency of fork truck; The connection gusset being simultaneously provided with can guarantee that boatswain chair connecting pin 8 is stressed even, works simultaneously, and then guarantees that the coupling assembling 3 of both sides is synchronized with the movement.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
