Description

Technical Field

[0001] The invention belongs to the technical design field of hoisting machinery used in tunnels, and in particular relates to a hydraulic cylinder support arm for a track laying machine. Background Art

[0002] In the process of tunnel traffic construction, the track paving project is in the middle of the civil engineering project and the equipment installation project in terms of the construction schedule. It is the next process of the civil engineering project and the first process of other equipment installation projects. The progress of tunnel track paving has a huge impact on the progress of subsequent equipment installation and commissioning. Among the various processes of tunnel track installation engineering construction, track laying and concrete pouring in the tunnel are key processes, and are also the most important and difficult to control part of the production progress. As the most critical equipment in this link, the technical performance of the tunnel track laying machine plays a vital role in the smooth progress of the entire operation process. At present, the forms of the roadbed in the tunnel generally alternate between integral roadbed, T-type sleeper roadbed, steel spring floating plate roadbed, etc.; the main changes in tunnel structure are: shield, horseshoe, rectangle, platform, civil air defense door, etc. In order to adapt to various tunnel structures and roadbed forms, the structure and span of the tunnel track laying machine must be changed accordingly to achieve machine laying. The space in the tunnel is small, and the tunnel track laying machine has many unfavorable factors such as many dangerous factors, inconvenient operation, and long operation time when changing the span and structure in the tunnel. Once the tunnel track laying machine in the tunnel stops using, the entire track laying process will stagnate, resulting in idle work. In the existing technical center, the tunnel track laying machine needs to be lifted by a gantry crane to change the span when changing the span, or the tunnel track laying machine needs to be disassembled when changing the span, which is very inefficient; and the working face often changes during the construction process. Each time the work face changes, the gantry crane needs to be disassembled and reassembled, affecting the progress of the project. Summary of the invention

[0003] In order to solve the deficiencies in the prior art, the present invention provides a hydraulic cylinder support arm for a track laying machine. The hydraulic cylinder support arm is used to lift the track laying machine from the bottom of the track laying machine, thereby changing the span or loading and unloading the track laying machine.

The upper support arms are respectively sleeved inside the first lower support arm, the second lower support arm, the third lower support arm and the fourth lower support arm. A vertically arranged height adjustment hydraulic cylinder is provided in each of the first lower arm, the second lower arm, the third lower arm and the fourth lower arm, and the fixed end of the height adjustment hydraulic cylinder is hinged to the inner bottom end of the first lower arm, the second lower arm, the third lower arm and the fourth lower arm, and the free end of the height adjustment hydraulic cylinder is hinged to the bottom end of the upper arm, respectively. An angle adjustment hydraulic cylinder is provided between the first lower arm and the second lower arm, and the fixed end of the angle adjustment hydraulic cylinder is hinged to the bottom end of the second lower arm, and the free end of the angle adjustment hydraulic cylinder is hinged to the upper end of the first lower arm.

[0018] Usage process:

[0019] A parallel support beam 7 is fixed to the bottom end of the main beam of the track laying machine 8. When the track laying machine is changed in span, the support of the hydraulic cylinder arm of the track laying machine is required for operation. When in use, the hydraulic cylinder arm of the track laying machine is transported to the bottom of the track laying machine 8, and the height adjustment hydraulic cylinder 4 in the first lower arm 21, the second lower arm 22, the third lower arm 23 and the fourth lower arm 24 is started at the same time. The free end of the height adjustment hydraulic cylinder 4 moves upward at a uniform speed, and the upper arm 3 moves upward at a uniform speed under the support of the free end of the height adjustment hydraulic cylinder 4. The support frame 31 at the top of the upper arm 3 moves to the bottom of the support beam 7 on the track laying machine 8. By starting the angle adjustment hydraulic cylinder 41 between the first lower arm 21 and the second lower arm 22, and simultaneously starting the angle adjustment hydraulic cylinder 41 between the third lower arm 23 and the fourth lower arm 24, the first lower arm 21 and the fourth lower arm 24 are deflected to the left under the push of the free end of the angle adjustment hydraulic cylinder 41, and the second lower arm 22 and the third lower arm 23 are also deflected to the left under the traction of the articulated beam 5. After the position is adjusted, the height adjustment hydraulic cylinder 4 in the first lower arm 21, the second lower arm 22, the third lower arm 23 and the fourth lower arm 24 is started at the same time, so that the support frame 31 is fixedly connected with the support beam 7, and the height adjustment hydraulic cylinder 4 continues to work, and then the track laying machine 8 is lifted up. After the track laying machine 8 is lifted up, the track laying machine 8 can be operated to change the span. When the track laying machine 8 needs to be transported, the transport trolley is moved to the bottom of the raised track laying machine 8, and the height adjustment hydraulic cylinders 4 in the first lower arm 21, the second lower arm 22, the third lower arm 23 and the fourth lower arm 24 are started at the same time, so that the free end of the height adjustment hydraulic cylinder 4 falls slowly and evenly until the track laying machine 8 falls onto the uniform speed trolley.
