Abstract

The utility model relates to a hook-removing device for heavy-tamping hammer, which is composed of a lifting hook (5) and a frame (1). The frame is a square case a bottom connected with a pulling handle (11). The utility model also comprises a limiting shaft (2), a rotating shaft (3), a connecting shaft (6) and a clamping plate (4). Two ends of the limiting shaft are fixedly connected with two horizontal case plates of the frame. The rotating shaft is arranged on one side of the limiting shaft and hinged with the horizontal case plate of the frame. The clamping plate is provided with two symmetric sections, with upper and lower ends as well middle of which are provided respectively with a circular hole; wherein, the circular hole on the upper end is connected with initial lifting base of hoisting machine, and the circular hole is middle is connected with the rotating shaft through pivot. Through the connecting shaft, the circular hole on the lower end is connected with the lifting hook. Handle of the lifting hook stretches into space formed by the limiting shaft and the rotating shaft between the two sections of the clamping plate, which makes the lifting hooked clamped. When lifting to height required, pull the frame to incline toward B direction, the lifting hook rotates around the connecting shaft and barycenter, and the heavy-tamping hammer departs from the lifting hook.

Description

The strong tripping gear that rams

Technical field

The utility model relates to ground compacting treatment facility, relates in particular to a kind of fixture of dynamic compaction machinery tool.

Background technology

Ram in the Foundation Treatment strong, requirement makes the hammer ram freely falling body ram ground when hammer ram is lifted by crane certain altitude.Along with the energy level of strong rammer require more and more higher (generic point rams 〉=300 tons. rice, present domestic maximum point rams energy level and reaches 1600 tons. rice), this just requires to make sling height and these two basic parameters of hammer ram weight increasing, itself influenced and secure context is considered by machinery, sling height can not be done very highly, so require the weight of hammer ram to continue to increase.After hammer ram increased the weight of, the difficulty of hammer ram off the hook had just strengthened, and traditional manually has been impossible, and traditional simple and easy detacher also destroys easily or is difficult for breaking off relations.

Summary of the invention

The utility model is intended to solve existing method and is difficult to the problem that realizes that the heavyweight hammer ram can't break off relations smoothly, and a kind of strong rammer tripping gear is provided.The utility model be used for big energy level (can reach 800 tons. rice) foundation dynamic consolidation handles construction, can shorten the activity duration of the every click of strong rammer greatly, reduces labor intensity of operating personnel, boost productivity.

A kind of strong rammer tripping gear, comprise suspension hook and support, support has the square frame that draws handle down for it, described strong rammer tripping gear also comprises limit shaft, turning cylinder, connecting axle and clamping plate, two horizontal deckle boards of the fixedly connected support square frame in described limit shaft two ends, described turning cylinder is positioned at a side of limit shaft and the horizontal deckle board of pivotally connected support square frame; Described clamping plate have symmetrical two, and their upper/lower terminal and centre are provided with a circular hole separately, and wherein, the circular hole of upper end connects the former flap seat of loop wheel machine, and middle circular hole and turning cylinder are pivotally connected, link to each other with suspension hook by connecting axle separately between the circular hole of lower end; And the shank of described suspension hook extend in the space that spacing axle sleeve between two clamping plate and rotary axle box constitute, so that suspension hook is in the state of being held before hammer ram breaks off relations in the lifting process, when lifting by crane desired height, draw under the lineoutofservice signal pull effect, making support to lopsidedness, suspension hook can center of gravity around the connecting axle pivoted.

It comprises that also an end connects the wire rope of loop wheel machine pedestal, and the other end of described wire rope is connected a described lower end of drawing, and its length and sling height are suitable.

Be with the major axis cover on the described limit shaft, the stage casing of described turning cylinder is with short sleeve.

Distance between described rotary axle box and the spacing axle sleeve is greater than the lateral width of the handle of suspension hook.

During hammer ram of the present utility model lifting, suspension hook top is clipped in and connects in the support between the major axis cover and short sleeve, simultaneously connect support draw on be a unhook wire rope by the hole, the other end is fixed on the support of loop wheel machine.When hammer ram lift by crane require when height, the detacher wire rope is just strained, when moving on hammer ram continues, connect the support moving axis axial-movement that under the lineoutofservice signal pull effect, rotates, shank skids off the major axis cover on the suspension hook at this moment, around the connecting axle axial-movement, hammer ram skids off suspension hook and does the movement of falling object then under action of gravity for hammer ram and suspension hook, has finished automatically-unhooked action.

Description of drawings

Below, provide the specific embodiment of the present utility model in conjunction with the accompanying drawings:

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is the utility model hammer ram off the hook view;

Fig. 3 is lateral view of the present utility model (not containing suspension hook).

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of strong rammer tripping gear, comprise suspension hook 5 and support, support 1 has the square frame that draws 11 down for it, the utility model also comprises limit shaft 2, turning cylinder 3, connecting axle 6 and clamping plate 4, two horizontal deckle boards of fixedly connected support 1 square frame in described limit shaft 2 two ends, described turning cylinder 3 is positioned at a side of limit shaft 2 and the horizontal deckle board of pivotally connected support square frame; Described clamping plate 4 have symmetrical two, their upper/lower terminal and centre are provided with a circular hole separately, and wherein, the circular hole of upper end connects the former flap seat of loop wheel machine, middle circular hole and turning cylinder 3 are pivotally connected, link to each other with suspension hook 5 by connecting axle 6 separately between the circular hole of lower end; And the shank of described suspension hook 5 extend in the space that the axle sleeve of the axle sleeve of two limit shafts 2 between the clamping plate 4 and turning cylinder 3 constitutes, so that suspension hook is in the state of being held before hammer ram breaks off relations in the lifting process, when lifting by crane desired height, draw under the lineoutofservice signal pull effect, making support 1 to lopsidedness, suspension hook 5 can center of gravity around connecting axle 6 pivoted, allow hammer ram break off relations.

It comprises that also an end connects the wire rope (not illustrating among the figure) of loop wheel machine pedestal, and the other end of described wire rope is connected described circular hole place of drawing 11, and its length and sling height are suitable.

Be with major axis cover 21 on the described limit shaft 2, the stage casing of described turning cylinder 3 is with short sleeve 31.

Distance between the short sleeve 31 of described turning cylinder 3 and the major axis of limit shaft 2 cover 21 is greater than the lateral width of the handle of suspension hook, and suspension hook 3 pommels can be from shifting out (see figure 2) when support 1 was rotated between them.

It is pointed out that when needing overweight hammer ram (＞35 tons), only need to adopt high-strength material to make each part of the utility model and get final product.
