Description

Trapezoidal ditch excavation construction equipment of road bed

Technical Field

The utility model belongs to a trapezoidal ditch excavation construction equipment of road bed.

Background

The cross section of the drainage ditch excavated beside the roadbed is in an inverted trapezoid shape. The drainage ditch is usually directly dug by a conventional excavator, and the cross section of the drainage ditch dug by an excavator bucket is rectangular. The side slope of the groove needs to be manually renovated into a ladder shape. The phenomena of over-excavation and under-excavation of an excavator bucket are serious, manual renovation is time-consuming and labor-consuming, a slope soil body is loosened to form deficient soil, if no lime soil inverted filter layer is arranged under a project ditch, the used concrete is seriously excessive when a concrete cover is arranged on a ditch surface layer in future, and the project cost is extremely disadvantageously controlled.

Therefore, the utility model discloses constitute by the excavator bucket, set firmly a trapezoidal cutting steel sheet in the rear end lower part of excavator bucket, the up end rear side of trapezoidal cutting steel sheet is equipped with the limiting plate, and the both ends limit of limiting plate extends to the outer end of trapezoidal cutting steel sheet, is the spacing distance on the lower extreme limit of the preceding terminal surface of trapezoidal cutting steel sheet and the both sides edge and is equipped with the cutting tooth.

The front end face of the trapezoid cutting steel plate is provided with stiffening steel plates at intervals. The cutting teeth of the trapezoidal cutting steel plate and the digging teeth of the digging bucket of the excavator are arranged in the same direction. The middle part of the front end of the limiting plate is provided with a groove for the lower part of the rear end of the corresponding bucket to be clamped in. The trapezoid cutting steel plate is an inverted trapezoid body. The cutting teeth are triangular cutting teeth with pointed front parts.

Above-mentioned structural design has realized the utility model discloses a purpose.

The utility model discloses increase trapezoidal cutting steel sheet at the excavator bucket, make the one shot forming in escape canal, have simple structure, reasonable in design, the preparation use cost is low, and is mechanical high, labour saving and time saving's advantage.

The utility model has the advantages as follows:

1. the utility model discloses the mechanicalness is high, and when excavator bucket dug the escape canal, the excavator bucket drove trapezoidal cutting steel sheet cutting and excavates the escape canal groove slope and be the inclined plane shaping, labour saving and time saving, and construction speed is fast.

2. The utility model has the advantages of simple and reasonable design, preparation and use cost are low, adopt the old and useless steel of building site to prepare the utility model discloses.

3. The utility model discloses safe in utilization, construction cost reduces 60 ~ 70%, and the working costs is low.

Detailed Description

As shown in fig. 1 to 5, the device for excavating and constructing the trapezoidal ditch of the roadbed is composed of an excavator bucket 5, wherein the excavator bucket is driven by an excavating arm 4 of an excavator to operate, the excavating arm is driven by the excavator, the excavator bucket adopts a bucket with the width of 55cm, and the structure of the traditional excavator is adopted, so that the structure is not repeated.

A trapezoidal cutting steel plate 3 is fixedly arranged at the lower part of the rear end of the excavator bucket, and the trapezoidal cutting steel plate is an inverted trapezoidal body. A1.5-2 cm thick steel plate for trapezoidal cutting of the steel plate is provided, the top width is 211cm, the bottom width is 51cm, the height is 77cm, and the periphery of the steel plate is polished to be an arc angle. Limiting plate 2 is arranged on the rear side of the upper end face of the trapezoidal cutting steel plate, the two end edges of the limiting plate extend to the outer end of the trapezoidal cutting steel plate, and the limiting plate plays a role in limiting the excavating depth of the excavator bucket. The limiting plate and the rear side of the upper end face of the trapezoidal cutting steel plate are fixed into a whole through welding. The middle part of the front end of the limiting plate is provided with a groove 8 for the lower part of the rear end of the corresponding bucket to be clamped in. The rear side edge of the groove is the front end face of the trapezoid cutting steel plate, and the width of the groove is matched with the width of the excavator bucket. When the trapezoidal cutting steel plate is arranged at the lower part of the rear end of the excavator bucket, the width of the excavator bucket of the corresponding part can be clamped into the groove, so that the corresponding part at the lower part of the rear end of the excavator bucket, the limiting plate and the joint edge of the corresponding part of the trapezoidal cutting steel plate are fixed into a whole through welding. The front end face of the trapezoid cutting steel plate is provided with an intrinsic stiffening steel plate 7 at intervals, the stiffening steel plate is 1-thick, 4-6 cm wide and used for enhancing the strength of the trapezoid cutting steel plate.

The lower end edge and the two side edges of the front end surface of the trapezoidal cutting steel plate are provided with cutting teeth 1 at intervals for cutting the construction surface of the trapezoidal ditch 6 in contact. The cutting teeth of the trapezoidal cutting steel plate and the digging teeth of the digging bucket of the excavator are arranged in the same direction. The cutting teeth are triangular cutting teeth with pointed front parts. The rear end surfaces of the plurality of cutting teeth are welded with the lower end edge and the two side edges of the trapezoidal cutting steel plate at the corresponding part into a whole.

As shown in FIG. 5, when in use, the trapezoidal cutting steel plate is welded and fixed with the lower part of the rear end of the excavator bucket into a whole. After the construction site is leveled, technicians discharge the drainage ditch to excavate two side lines according to a design drawing and scatter lime marks. The excavator is in place, and the excavator bucket is controlled to excavate through the lime mark line. When the excavator bucket excavates ground soil, the trapezoidal cutting steel plate is driven to cut the side walls and the bottom surface of two sides into a trapezoidal shape at one time. The ditch is excavated, and the effect of one-step forming without manual renovation is achieved. The limiting plate arranged on the excavator bucket can control the excavation depth of the excavator bucket, and the error is controlled within 3 cm.

In a word, the utility model discloses increase trapezoidal cutting steel sheet at the excavator bucket, make and dig escape canal one shot forming, have simple structure, reasonable in design, the preparation use cost is low, and is mechanical high, labour saving and time saving's advantage.
