Abstract

The utility model provides a deslagging operation platform for shield tunnel construction, which is characterized by comprising a feeding hopper, a discharging hopper, a bearing platform, an operation platform, an excavator walking beam, an excavator support column, a chute and a slag field retaining wall. The feeding hopper is connected with the discharging hopper, the feeding hopper is arranged at the position close to the inner side of a slag field, and the discharging hopper is arranged at the position on the outer side of the slag field. The operation platform is positioned on the lateral side of a hopper and above the bearing platform. By means of the deslagging platform, slurry loading and transporting efficiency is obviously improved, slurry splashing is greatly reduced, working time and water quantity spent in cleaning are reduced correspondingly, and the whole process is environmentally-friendly and efficient.

Description

The shield-tunneling construction job platform of slagging tap

Technical field

The utility model relates to a kind of job platform of slagging tap, particularly a kind of shield-tunneling construction job platform of slagging tap.

Background technology

The dregs that shield driving produces in pressure chamber through Jia Shui, add the mud mixture that foaming agent is adjusted to a kind of plastic flowing state, dregs has higher water content, is muddy.The transport courses of dregs is generally: through rail transport, the extremely interim slag field of vertical-lift, install to through the slag field and be transported to the waste field on the transport vehicle in the hole, accomplish tapping process.

Installing to this link of transport vehicle from the slag field, general usage mining machine shipment.The phenomenon that inevitably can exist mud to splash everywhere causes bigger pollution, needs to send special messenger's cleaning.Shipment is consuming time longer, influences the efficient of slagging tap, and the manpower and the water of each consumed cleaning are a lot, is unfavorable for construction cost control.

The utility model content

In order to remedy above-mentioned defective in the prior art; The utility model provides a kind of job platform of slagging tap, and it is characterized in that: comprise elevating hopper, drain hopper, bearing platform, operating platform, excavator walking beam and support column, chute and slag field barricade, elevating hopper connects drain hopper; The elevating hopper position is inboard near the slag field; The drain hopper position is positioned at the outside, slag field, and operating platform is in the hopper side, above the bearing platform.

Further, drain hopper is divided into two parts, comprises fixing slag releasing channel and movable door.

Further, the excavator walking beam is twice, and twice beam distance between center line is identical with excavator crawler belt distance between center line, and the width of per pass beam is greater than crawler width.

Further, door is by the hydraulic means folding and unfolding.

The utlity model has following advantage after the improvement:

Mud shipment efficient obviously improves, and the mud splash phenomena significantly reduces, each cleaning cost man-hour, the also corresponding minimizing of the water yield, relatively environmental protection of whole process, efficient.

Description of drawings

Fig. 2 platform side view of slagging tap;

Fig. 3 platform elevation of slagging tap.

Among the figure: the 1-elevating hopper, the 2-drain hopper, the 3-bearing platform, the 4-chute, the 5-hydraulic means, the 6-splashproof door curtain made of cloth, 7-slag field barricade, 8-excavator walking beam and support column, the 9-operating platform, the 10-operating platform goes on foot ladder up and down

The specific embodiment

Shown in Fig. 1～3, in interim slag field the special-purpose platform of slagging tap is installed, excavator cooperates.The platform of slagging tap mainly is divided into three parts, and a part is an elevating hopper 1, and the position is inboard near the slag field; Second portion is a drain hopper 2, and the position is positioned at the outside, slag field; Third part is a bearing platform 3.

Elevating hopper 1 is a pyramidal structure, is processed by the 10mm steel plate.Connect chute 4, guarantee that the mud that exceeds elevating hopper 1 capacity flows back to the slag field along the ramp, processed by the 10mm steel plate.

Drain hopper 2 is divided into two parts: one is fixing slag releasing channel; Two is movable door.Door is by hydraulic means 5 folding and unfoldings.Drain hopper 2 is processed by the 10mm steel plate.The splashproof door curtain made of cloth 6 is suspended on around the door, and what produce when preventing mud from high falling splashes down.

Bearing platform 3 is by the processing of I25 worker's steel, frame construction.Height 4000mm, width 4000mm (not comprising the operating platform width).Operating platform 9 is in the hopper side, and bearing platform 3 tops arrange the special messenger on operating platform 9, to be responsible for operation hydraulic means 5 folding and unfolding doors.The visual field is better, can fully grasp the state of transport vehicle, door, in time carries out corresponding operating.

Excavator walking beam and support column 8 adopt concrete structure.Walking beam is twice, and twice beam distance between center line is identical with excavator crawler belt distance between center line, and the width of per pass beam is greater than crawler width, guarantees the safety of excavator operation in the above and smooth and easy.

With the mud elevating hopper 1 of packing into, mud flows into drain hopper 2 transport vehicle of packing into along the inclined-plane to excavator automatically, can not produce in the whole process and spatter leakage, has solved environmental pollution problems in the slag field.

Though the embodiment of the utility model has been described with reference to the drawings above, it will be understood by those skilled in the art that under the situation that does not break away from the utility model scope and spirit, can make various modification and variation to the utility model.Therefore, should be appreciated that the above embodiments are not restrictions, but the illustrating of various aspects.
