Description

Shunt fender for shield continuous tunneling construction

Technical Field

The utility model relates to the technical field of tunnel construction, in particular to a diversion fender for shield continuous tunneling construction.

Background

During the shield construction, the muck excavated by the shield machine is transported into a muck bucket running behind the shield machine by a transport device, the muck bucket is in a multi-section train form with an open top, however, during the actual construction process, as the shield machine continuously excavates, the transport device does not stop to transport the muck into the muck bucket, and after one row of muck buckets is full, a power battery truck of the muck bucket adjusts the next row of muck buckets to be aligned with the slag outlet end of the transport device to perform the soil loading switching action, however, during the process, the muck falls into the track more or less from the gap between two adjacent rows of muck buckets, and the muck foaming agent and the like easily cause the dump of the battery truck to fall off the track, and the muck outside of the muck bucket is usually removed by manual cleaning during the parking, which aggravates the equipment abrasion and the manpower, material, and cost caused by equipment maintenance, The waste of machines and tools causes that the shield construction can not realize continuous tunneling.

Therefore, how to solve the problem of the falling of the residual soil in the soil loading switching action becomes a technical problem to be solved urgently by the people in the field.

Through public search, relevant patents with high approximation are not found.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art, and provides the shunting mudguard for the shield continuous tunneling construction, which can prevent muck from falling into a track, does not need to be stopped and cleaned manually, can solve the problems of waste of manpower and machines and safety in the shield construction process, and effectively solves the problem of mechanical abrasion caused by discontinuous construction.

A shunt fender for shield continuous tunneling construction is provided, the middle part of the fender is raised upwards, two ends of the fender extend downwards and are connected with the tops of two adjacent rows of slag soil buckets, and the fender comprises a first baffle and a second baffle; the bottom end of the second baffle plate is hinged with the top steel plate of the next-stage slag-soil bucket, and the top end of the second baffle plate is hinged with the top end of the first baffle plate; the bottom end of the first baffle is fixedly connected with the top end of the upper-stage slag soil hopper in a hanging mode, and a plurality of electric control spring inner supports are fixedly connected to the downward plane of the first baffle and the second baffle.

Moreover, a hook is fixedly arranged at the end part of the first baffle; the top of the tail end of the muck bucket in the running direction is fixedly provided with a hanging plate which is matched with and hung on a hook.

And the top ends of the first baffle plate and the second baffle plate are hinged through a hinge.

The utility model has the advantages and technical effects that:

the utility model relates to a diversion fender for shield continuous tunneling construction, which is characterized in that a first fender and a second fender are hinged to form a pointed top at a connecting gap of two adjacent rows of muck buckets, muck falls into the muck bucket of the previous stage or the next stage from the direction of the pointed top, the muck is prevented from falling onto a track through the gap between the muck buckets, an inner support of the pointed top is formed by an electric control spring inner support, and the problem that the mudk impacts the first fender and the second fender, so that a hook is separated from a hanging plate, and the fender is folded and fails is avoided.

The shunting mudguard for shield continuous tunneling construction effectively utilizes the time for switching the muck bucket of the storage battery car to suspend tunneling, does not need to stop to clean the muck scattered on a track, solves the problems of unnecessary manpower and machine consumption and mechanical abrasion caused by the interrupted work of a shield machine, and has simple structure and low cost.
