Abstract
The utility model relates to an underground construction machine, more particularly a continuous wall grab bucket used grab bucket body with increase weight. The grab bucket body comprises a bucket head bracket (1), a pair of buckets (3) installed at the left and right sides of the lower part of the grab bucket body, and a pair of scrapers (2), wherein the bucket head (3) is a quarter circle member, the center of the bucket head is rotatably connected with the lower end of the bucket head bracket; the both sides and the bottom center of the scrapers are connected with the bucket head bracket with connecting rods, the bucket head bracket is provided with a cavity (1) filled with heavy object, a sealing steel plate (4) is installed at the cavity opening, and the sealing steel plate is mechanically connected with the cavity opening. The utility model increases the weight of grab bucket and improves working efficiency under the prerequisite of retaining the volume of equipment.
Description
Technical field
The utility model relates to underground construction machinery, particularly a kind of diaphragm wall grab bucket grab bucket body.
Background technology
At present, the hydraulic diaphragm wall grab of digging ground down comprises bucket a bearing, cleaning shoe and bucket head, and a bucket bearing has a cavity that opens wide, and excavates the silt stone that gets up and all enters wherein, is difficult to clean.When such structure runs into harder earth formation or cutting depth and surpasses 30 meters, because mass deficiency own.Cause excavating ineffective, operating efficiency is low, and grab bucket body opening angle is little, and mud extraction is obstructed, influences construction speed.
Summary of the invention
Technical problem to be solved in the utility model is existing grab bucket body running inefficiency, and mud extraction is obstructed, and a kind of weightening finish diaphragm wall grab bucket grab bucket body is provided.The utility model has increased grab bucket physique amount under the prerequisite that keeps equipment volume, improved operating efficiency.
The utility model is achieved in that a kind of weightening finish continuous wall grab grab bucket body, comprise a bucket bearing, be distributed in a pair of bucket and a pair of cleaning shoe of the left and right sides, its underpart, the bucket head is 1/4 circle parts, and its center is with the rotating connection bucket head of rotating shaft bearing lower end; With connecting rod connection bucket head bearing, a described bucket bearing is provided with cavity, in the described cavity weight is housed in the middle of cleaning shoe both sides and the bottom, and the cavity mouth is provided with the sealing steel plate, sealing steel plate and described cavity mouth mechanical connection.
Described sealing steel plate adopts bolt to be connected with described cavity mouth.
Described sealing steel plate and described cavity mouth are to be articulated and connected with the plug housing on a latch and the bucket bearing.
Described sealing steel plate and described cavity mouth are welded to connect.
Weight is an iron sand in the described cavity.
A bucket of the present utility model bearing cavity is airtight, silt stone can not enter wherein, thereby need not clean, weight is housed in the cavity, makes under the prerequisite of holding device volume more than the whole grab bucket weightening finish 800kg, make the bucket head ground pressure increase, run into the hardpan structure or still can effectively excavate below 30 meters underground, open to close and utilize cleaning shoe cutting force also to increase thereupon along with bucket head, mud extraction is more smooth and easy, thereby has improved operating efficiency 20%-30%.
Description of drawings
Provide the specific embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is an elevation of the present utility model;
Fig. 2 is a described bucket bearing schematic diagram.
The specific embodiment
As depicted in figs. 1 and 2, a kind of weightening finish continuous wall grab is with the grab bucket body, comprises a bucket bearing 1, is distributed in a pair of bucket 3 and a pair of cleaning shoe 2 of its left and right sides, and bucket 3 is 1/4 circle parts, and its center is with rotating shaft connection bucket head bearing 1 lower end rotationally; Cleaning shoe 2 both sides and bottom are middle with connecting rod connection bucket head bearing 1; A described bucket bearing 1 is provided with cavity, in the described cavity weight is housed, as iron sand, can make more than the whole grab bucket weightening finish 800kg, the cavity mouth is provided with sealing steel plate 4, sealing steel plate 4 and described cavity mouth mechanical connection, connected mode can be that bolt connects, welds or utilize the plug housing hinged (Fig. 2 is for being welded to connect) on a latch and the bucket bearing body.The utility model is under the prerequisite of holding device volume, make bucket head ground pressure increase, run into the hardpan structure or still can effectively excavate below 30 meters underground, along with bucket head is opened to close and is utilized cleaning shoe cutting force also to increase thereupon, mud extraction is more smooth and easy, thereby has improved operating efficiency 20%-30%.
