Abstract
A kind of scraper bowl and method having the trapezoidal gutter channel excavation of shoulder, is related to a kind of excavator, more particularly to a kind of power shovel, for there is the excavation of the trapezoidal gutter groove of shoulder, carries out gutter groove using the scraper bowl and once excavates molding.When carrying out trapezoidal gutter channel excavation using ordinary excavator, needs to backfill the earthwork and backfilling of earthwork quality is not easy to control, progress is slow.Main bucket upper board 1, main bucket lower panel 8, main bottom sheet 13, main bucket wallboard 4, bucket epaulement plate 2, bucket shoulder bottom plate 3, bucket shoulder top plate 14, bucket shoulder back plate 12 etc. weld together, form the Contraband font variable cross-section semi-closed structure scraper bowl that a front view is specific shape, excavating groove using the scraper bowl can be with one-pass molding, foundation plane or less the earthwork is not disturbed, ensure gutter satisfactory quality, construction efficiency is higher, and cost is relatively low.
Description
Technical field
The present invention relates to a kind of excavators, more particularly to a kind of power shovel, for there is the trapezoidal gutter groove of shoulder
The scraper bowl of excavation.
Background technique
Must excavate groove before trapezoidal draining channel forming, groove also must be it is trapezoidal, during the channel excavation of gutter, open
Digging size and design size should be consistent, and it is bigger than design size to excavate size, then needed in the forming process of gutter at
Profile material (such as concrete) filling, this part moulding material of filling cannot participate in measuring, that is to say, that this part moulding material
Metering money cannot be taken, causes to waste, cost improves；It is smaller than design size to excavate size, gutter compact dimensions after the completion
It is not inconsistent with design size, is not able to satisfy design drawing requirement, it is off quality.
In the trapezoidal groove digging process of undisturbed soil ground, slot bottom original state foundation soil must not be disturbed；It is time-consuming using hand excavation
Arduously, inefficiency；It is excavated using ordinary excavator, is unable to complete independently and excavates task, it is necessary to which cooperation is manually excavated, returned
It fills out, the section configuration and cross dimensions of design drawing requirement could be formed, when manually being excavated using ordinary excavator cooperation,
The following soil body of foundation plane has destroyed, and design section backfilling of earthwork quality below is not easy to control, and excavating efficiency is also not very high.
Summary of the invention
It is an object of the invention to provide a kind of scraper bowls and method for having the trapezoidal gutter channel excavation of shoulder, are carried out using the scraper bowl
Trapezoidal gutter channel excavation, it is ensured that trapezoidal gutter groove once excavates molding, guarantees the trapezoidal gutter after the completion of excavating
Groove quality is met the requirements.
To achieve the above object, the invention adopts the following technical scheme:
According to the trapezoidal gutter size that design drawing requires, bottom width, the groove both sides of trapezoidal gutter groove are calculated
The gradient, the top clear span of groove, shoulder breadth and the vertical height in trapezoidal gutter, it is ensured that: it is main bucket lower panel 8 width dimensions and ladder
The bottom width size of shape gutter groove is consistent, main bucket wallboard 4 gradient of vertical direction and trapezoidal gutter groove at scraper bowl mouth
The gradient on both sides is consistent, the sum of width dimensions and groove top clear span size and both sides shoulder of main bucket upper board 1 phase
Unanimously, the size of bucket shoulder bottom plate 3 and the shoulder breadth size in trapezoidal gutter are consistent, and main bucket upper board 1 is being shoveled with main bucket lower panel 8
The high size of hanging down of vertical range size and trapezoidal gutter at quarrel is consistent.
According to above-mentioned size, related specification requirement and dipper capacity, one piece of main bucket upper board, 1, one piece of main bucket lower panel
8,4, two blocks of the main bucket wallboard of 13, two blocks of the main bottom sheet of one piece of arc-shaped, 2, two pieces of bucket epaulement plate bucket shoulder bottom plate, 3, two pieces of bucket shoulder tops
14, two blocks of bucket shoulder back plates 12 of plate etc. weld together, and form the Contraband font variable cross-section half that a front view is specific shape and seal
Close structure scraper bowl.
For the stability and useful life longevity for further strengthening the scraper bowl, two pieces of 9, two pieces of bucket shoulders of interior reinforcing rib that struggle against are welded
Reinforcing rib 10 connects two pieces of protective plates 5.
To further increase scraper bowl working efficiency, it is connected with several 7, two side teeth 6 of main bucket tooth.
When using scraper bowl, need to match by the dynamical system of attachment device 11 and excavator.
Before carrying out gutter channel excavation, setting-out is measured first, it is ensured that the linear beauty of ditch body, straight line is straight, curve
It is round and smooth；Its cross dimensions must be accurate when channel excavation, and bottom of trench is straight, and without landslide in ditch, no ponding, no-sundries, corner meets
Design requirement；To guarantee that excavator central axes and gutter axis essentially coincide in digging process, be convenient for excavator operation, it is ensured that
Molding gutter meets the requirements；After molding, it is ensured that the Slope leveling in gutter, stabilization are forbidden to paste slope；It, need to be into after excavation of foundation pit
Row bottom of trench elevation repetition measurement；After the completion of excavation, should properly protect measure in time, prevent the disturbance of substrate soil as far as possible.
Compared with prior art, beneficial effects of the present invention are as follows: a kind of scraper bowl having the trapezoidal gutter channel excavation of shoulder
And method can once excavate gutter ditch Slot shaping, while excavate gutter shoulder Slot shaping, excavation shaping efficiency is higher, molding
There is the cross dimensions of shoulder trapezoidal groove to meet drawing requirement, the exposed sideline for forming shoulder trapezoidal groove is smooth.
