Abstract
The utility model discloses a crane suspension hook anti-falloff locking plate device which is characterized by including a fixed clamping board, a movable clamping board and a crane suspension hook, the upper end of the fixed clamping board is connected with the upper root part of the crane suspension hook, the movable clamping board is connected with the lower end of the fixed clamping board, the fixed clamping board and the movable clamping board are located in a hook of the suspension hook, a pressure spring is arranged between the fixed clamping board and the upper root part of the crane suspension hook, the connection parts of the fixed clamping board and the movable clamping board are provided with upturned edgefolds, the upturned edgefolds are fastened by bolts, and the lower end of the movable clamping board is provided with a notch for clamping the crane suspension hook. The fixed clamping board and the movable clamping board of the crane suspension hook anti-falloff locking plate device are connected, in the using process of the crane suspension hook, only the movable clamping board is worn by a steel wire rope, the crane suspension hook can be completely clamped by the notch of the movable clamping board, the safe use of the crane suspension hook can be guaranteed, only the movable clamping board needs to be replaced when the e crane suspension hook is repaired, and the repair cost is reduced.
Description
Technical field
The utility model relates to a kind of crown block hook anticreep locking plate device, especially relates to a kind of movable clamp of crown block hook anticreep locking plate.
Background technology
In order to guarantee the not sharp hook of overhead traveling crane lifting steel rope, a day coupler head anti-drop device need to be set.Existing day coupler head anti-drop device is the whole clamp of upper root connection at crown block hook, whole clamp is positioned at the gib head of suspension hook, between the upper root of whole clamp and crown block hook, be provided with pressure spring, whole clamp is withstood on the gib head inwall that abuts against crown block hook by pressure spring, the steel rope that hangs weight enters crown block hook inside and is lived by entire card board, and steel rope is surrounded can not break off relations.While laying down weight, need in suspension hook, to pull whole clamp by hand, to steel rope, reserve the space of unhook.The deficiency of this day coupler head anti-drop device is: because entire card front edge of board portion is often subject to the wearing and tearing of steel rope, steel rope enters crown block hook inside and can not be lived by entire card board, easily makes anti-drop device lose efficacy, affect overhead traveling crane use; When suspension hook maintenance and repair, whole clamp damages needs integral replacing, has increased service expenditure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of crown block hook anticreep locking plate device, and whole clamp is become by fixing chuck plate and the clamp that movable clamp is connected, and has a wearing and tearing activity clamp, reduces the feature of service expenditure.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of crown block hook anticreep locking plate device, is characterized in that: comprise fixing chuck plate, movable clamp and crown block hook; The upper end of described fixing chuck plate is connected with the upper root of crown block hook, and described movable clamp is connected to the lower end of fixing chuck plate, and described fixing chuck plate and movable clamp are all positioned at the hook of crown block hook.
The further improvement that the utility model is done is: between the upper root of described fixing chuck plate and crown block hook, be provided with pressure spring.Described fixing chuck plate and movable clamp are equipped with flanging upward in junction, described flanging upward passes through bolted; The lower end of described movable clamp is provided with the notch that blocks crown block hook.
The beneficial effect that adopts technique scheme to produce is: the fixing chuck plate of this device is connected with movable clamp, steel rope wearing and tearing activity clamp only in suspension hook use procedure, the notch of movable clamp can block crown block hook completely, the safe handling of guarantee suspension hook, maintenance only need replacing activity clamp during suspension hook, reduces service expenditure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
As shown in the figure: 1 front side support plate, 2 fixing chuck plates, 3 spring pressure hooks, 4 bolts, 5 movable clamps, 6 notches, 7 crown block hooks.
The specific embodiment
Contrast Fig. 1 is used step to be described further to operation of the present utility model:
Embodiment 1: a kind of crown block hook anticreep locking plate device, is characterized in that: comprise fixing chuck plate 2, movable clamp 5 and crown block hook 7; The upper end of described fixing chuck plate 2 is connected with the upper root of crown block hook 7, and described movable clamp 5 is connected to the lower end of fixing chuck plate 2, and described fixing chuck plate 2 and movable clamp 5 are all positioned at the hook of crown block hook 7.
The using method of the present embodiment: the upper end of fixing chuck plate 2 has multiple with the mode that the upper root of crown block hook 7 is connected: can be radial type with the non-return mechanism of single direction, or 2 of fixing chuck plates are as a spring leaf, fixing chuck plate 2 can only be opened to the gib head inner side of suspension hook 7.The steel rope that hangs weight enters in suspension hook 7, be fixed clamp 2 and movable clamp 5 and blocks, and overhead traveling crane end of run, manually pulls open fixing chuck plate 2 and movable clamp 5, reserves the space of unhook to steel rope, the decoupling device lifting work of having unloaded.
Embodiment 2: a kind of crown block hook anticreep locking plate device, is characterized in that: comprise fixing chuck plate 2, movable clamp 5 and crown block hook 7; The upper end of described fixing chuck plate 2 is connected with the upper root of crown block hook 7, and described movable clamp 5 is connected to the lower end of fixing chuck plate 2, and described fixing chuck plate 2 and movable clamp 5 are all positioned at the hook of crown block hook 7.Between described fixing chuck plate 2 and the upper root of crown block hook 7, be provided with pressure spring.Described fixing chuck plate 2 and movable clamp 5 are equipped with flanging upward in junction, described flanging is upward fastening by bolt 4; The lower end of described movable clamp 5 is provided with the notch 6 that blocks crown block hook 7.
The using method of the present embodiment: fixing chuck plate 2 both sides, upper end are provided with front side support plate 1 and are connected to the upper root of crown block hook 7 by cross bolts, pressure spring is through in cross bolts, one side of pressure spring is withstood the upper root of crown block hook 7, opposite side is the spring pressure hook 3 of pushing down fixing chuck plate 2, and fixing chuck plate 2 can only be opened to the gib head inner side of suspension hook 7 like this.The steel rope that hangs weight enters in suspension hook 7, be fixed clamp 2 and movable clamp 5 and blocks, and the notch 6 of movable clamp 5 lower ends can block crown block hook 7, has increased the stability of this device, ensures suspension hook safe handling.Overhead traveling crane end of run, pulls open fixing chuck plate 2 and movable clamp 5, reserves the space of unhook to steel rope, and the decoupling device lifting work of having unloaded only need be changed the movable clamp 5 of wearing and tearing during maintenance.
