Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following description will clearly describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the pipe jacking failure towing device of the present embodiment includes: the tension mechanism 102 drags the base 103 and the jack 104 back.
The back dragging base 103 is a hexahedral steel plate and is arranged in the working well, and the larger surface of the back dragging base 103 faces the pipe jacking machine head 101, so that the back dragging base 103 can just enter the working well and has the optimal size.
The tension mechanism 102 is a plurality of tension rods which can be disassembled in the axial direction, the first end of the tension mechanism 102 is connected with the push bench head 101, and the connection can be realized in a manner of welding, riveting, buckling and the like, in the embodiment, the tension mechanism 102 is connected with the push bench head 101 in a buckling manner; the second end of tension mechanism 102 is connected on the great face that drags base 103 back, also can connect through modes such as welding riveting buckle, in this embodiment, adopts the buckle mode to connect, perhaps sets the tension bar to one end inflation, the other end sets firmly the buckle that is used for the adjacent tension bar expansion tip of joint, makes things convenient for the operation of disconnection and connection between the part like this, has not only improved work efficiency and has used manpower and materials sparingly.
Jack 104 is arranged between the larger surface of back-dragging base 103 facing to pipe push bench head 101 and the working well, and jack 104 can push back-dragging base 103 to move away from pipe push bench head 101.
The device is used for dragging the failed pipe jacking machine head 101 back, the device is simple in structure and convenient to operate, operation can be carried out in a limited working space, working efficiency is greatly improved, and labor cost is low.
In this embodiment, an infrared device is further disposed at the center of the back dragging base 103, and the infrared device can adjust the center of the back dragging base 103 to correspond to the center of the push bench head 101, so as to drag the push bench head 101 out with a smaller force.
In this embodiment, the jacks 104 may be arranged in 2 groups, one group of two jacks, and the two jacks are respectively arranged at four corners of the back dragging base 103, so as to distribute force, so that the pushing force of the jacks is concentrated and the back dragging is quicker; preferably, the jack 104 is a hydraulic jack.
In this embodiment, the tension mechanism 102 is formed by connecting a plurality of sections of steel bars, and is connected between two adjacent steel bars through a buckle, so that the length of the steel bars can be conveniently adjusted after the steel bars are pulled out by a certain distance, thereby improving the working efficiency and saving manpower and material resources.
The specific working process of the device is as follows: when the head of the pipe jacking machine breaks down or/and after the pipeline breaks, the device is placed in a working well, the first end of the tension mechanism 102 is connected with the head 101 of the pipe jacking machine, the second section of the tension mechanism is connected with the back dragging base 103, the jack 104 is placed between the back dragging base 103 and the wall of the working well, the jack 104 is started to enable the back dragging base to move back to the head 101 of the pipe jacking machine, so that the tension mechanism 102 and the head 101 of the pipe jacking machine are driven to do back dragging movement, when the movement has a certain distance, the movement is generally a section of pipeline at the back dragging position, the length of the tension mechanism 102 is adjusted (if a tension rod structure such as a steel bar is adopted, the steel bar at the pulled-out pipeline position is separated from the adjacent steel bar), and the back pulled-out pipeline. Then repeating the actions until the whole pipe jacking machine head 101 is completely dragged back to the working well, and hoisting the working well by using a crane to remove the fault; the back-dragging device is simple in structure and convenient to operate, greatly improves the back-dragging work efficiency when the pipe jacking machine head 101 breaks down, is low in labor cost and suitable for large-scale popularization, and can mainly keep the follow-up secondary jacking of a pipeline instead of only being used for open pipe laying operation.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
