Description
Technical Field
The utility model belongs to the technical field of municipal engineering construction equipment, and particularly relates to a muck truck for shield construction of a small clearance working well.
Background
Along with the development of urban underground space in China, more and more projects are adopted for construction by adopting a shield method, and in the construction of the earth pressure balance shield method, muck generated by shield tunneling is horizontally transported to a position of a hoisting hole of a working well through a muck truck, and then is vertically hoisted out of the well by a gantry crane. During shield construction, in order to meet the requirement of one-ring tunneling slag discharge amount, 1 electric storage battery car and 4 muck cars are required to be grouped into a group to realize muck circulation transportation, namely, one-ring tunneling and one-time slag discharge are realized, in the construction of a general subway tunnel shield method, the muck cars and the electric storage battery cars all travel to the lower part of a gantry crane of a station due to the long length of the station, a muck bucket is vertically lifted by the gantry crane to discharge slag, for a small clearance working well, the size of a hoisting hole is 8.2 multiplied by 11m, the muck cars and the electric storage battery cars cannot travel to the lower part of the gantry crane at one time, the muck cars behind the first muck car cannot vertically lift out of the well by the gantry crane to discharge slag, and the construction efficiency is greatly reduced.
Therefore, it is necessary to provide a muck truck for shield construction of a small clearance working well, which has the advantages of low cost, simple manufacture, convenience and practicality, ensures smooth slag discharge and improves the construction efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model provides a muck truck for shield construction of a small clearance working well, which is low in cost, simple to manufacture, convenient and practical, ensures smooth slag discharge and improves the construction efficiency in order to overcome the problems that a muck truck and a battery truck of the small clearance working well cannot walk below a gantry crane at one time, is inconvenient to construct and greatly reduces the construction efficiency in the prior art.
In order to realize the purpose, the utility model is realized by the following technical scheme:
the utility model provides a muck truck for shield construction of a small clearance working well, which comprises a fixed block 1, a jigger 2 and a muck bucket 3, wherein the fixed block is fixedly connected with the jigger; jigger 2 and dregs fill 3 be connected fixedly through fixed block 1, fixed block 1 symmetrical arrangement is in jigger 2 and dregs fill 3's both sides to adopt full weld to connect, the one end of jigger 2 is provided with connecting lock 4.
Preferably, the sizes of the jigger 2 and the muck bucket 3 are matched with the size of the hoisting hole 5 of the working well.
The utility model has the beneficial effects that:
the utility model adopts the storage battery car as a power source to drive the muck car to horizontally transport, realizes one-ring muck discharging in shield tunneling, has the advantages of economic material, simple manufacture and strong practicability, solves the problems that the shield working well has small space and cannot smoothly realize the vertical lifting of muck out of the well, integrates the muck bucket and the bottom jigger, can lift out of the well and discharge slag one by one, realizes the smooth lifting of muck out of the well, improves the muck discharging efficiency in small-clearance shield construction, and accelerates the shield construction speed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-2, the muck truck for shield construction of the small clearance working well comprises a fixed block 1, a jigger 2 and a muck bucket 3; barring 2 and dregs fill 3 be connected fixedly through fixed block 1, 1 symmetrical arrangement of fixed block is in the both sides of barring 2 and dregs fill 3, and adopt the full weld connection, the overall stability of dregs car when can improving dregs horizontal transport, bear the dead weight of lower part barring 2 when satisfying the perpendicular handling of dregs car again, lower part barring 2 can not drop when making dregs car hoist and mount and cause the potential safety hazard, barring 2 and 3 sizes of dregs fill match the size of working well hoist and mount hole 5, the one end of barring 2 is provided with connecting lock 4, be used for between the dregs car, the connection between dregs car and the storage battery car 6.
The working process of the utility model is as follows:
when the small clearance working well shield construction muck transportation device is used for transporting small clearance working well shield construction muck, firstly, four muck vehicles and the battery car 6 are arranged into a group, the battery car and the four muck vehicles are arranged in sequence from front to back (the shield tunneling direction is the front), and the whole formed by the battery car and the four muck vehicles is arranged on the track 8 in the working well 7; then, when slag is discharged, the storage battery car 6 is used as a power source to drive the muck cars to be horizontally transported from the shield tunnel 9, the last muck car runs to the position of the working well hoisting hole 5, the gantry crane vertically hoists the last muck car out of the working well 7 for deslagging, after deslagging, the muck cars are temporarily placed on the ground, the next to last muck car in the pit is pushed to the position of the working well hoisting hole 5, the working well 7 is hoisted out again for deslagging, the process is circulated in sequence, all the muck cars are hoisted out of the well for deslagging, and finally the ground muck cars are hoisted down one by one to be connected with the storage battery car 6, so that one-ring slag discharge of shield tunneling is realized.
The utility model adopts the storage battery car 6 as a power source to drive the muck car to horizontally transport, realizes one-ring muck discharging in shield tunneling, has the advantages of economic material, simple manufacture and strong practicability, solves the problems that the shield working well has small space and cannot smoothly realize the vertical lifting of muck out of the well, integrates the muck bucket and the bottom jigger, can lift out of the well and discharge slag one by one, realizes the smooth lifting of muck out of the well, improves the muck discharging efficiency in small clearance shield construction, and accelerates the shield construction speed.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
