Description

Technical Field

[0001] The invention relates to the technical field of installation vehicles, in particular to a pipeline auxiliary installation vehicle with a self-leveling workbench. Background Art

[0002] At present, most domestic coal mines have poor working conditions underground, with uneven roads, many up and down ramps, and left and right inclinations. The pipeline auxiliary installation vehicles on the market are equipped with a single working platform. The platform can only move up and down, rotate left and right, and the working platform cannot be adjusted at multiple angles, making it difficult to reach the pipeline connection; most pipeline auxiliary installation vehicles do not have a working platform.

[0003] For pipeline auxiliary installation vehicles without working platforms, workers need to use escalators to go to the pipeline joints to install the bolts when installing pipeline connection bolts, which is unsafe and inefficient. For pipeline installation vehicles equipped with working platforms, there is only a single working platform. If the pipeline is long, the single platform can only install the bolts at the pipeline joints. The other end of the pipeline needs to be installed with a hanging rope, which still needs to be installed with the help of an escalator. The working platform can only move vertically up and down and rotate left and right. It cannot be adjusted at multiple angles or self-leveled to adapt to various road conditions. The bolts on the other side of the pipeline cannot be reached, and the escalator is still needed to install the bolts. In addition, the working platform is not equipped with an external air port, which is inconvenient to connect other pneumatic equipment; there is no emergency stop button, so when danger occurs, the workers on the working platform cannot immediately cut off the power output. For this reason, a pipeline auxiliary installation vehicle with a self-leveling workbench is proposed. Summary of the invention

[0004] The object of the present invention is to provide a pipeline auxiliary installation vehicle with a self-leveling workbench to solve the problems raised in the above background technology.

[0014] Preferably, a second oil cylinder is hinged on one side of the base, and a push rod end of the second oil cylinder is hinged on one side of the first connecting frame.

[0015] Preferably, a third oil cylinder is hinged on one side of the support frame, and a push rod end of the third oil cylinder is hinged on one side of the second connecting frame;

[0016] When the push rod ends of the second oil cylinder and the third oil cylinder are extended, the bottom plate is in an upward adjustment state, and when the push rod ends of the second oil cylinder and the third oil cylinder are retracted, the bottom plate is in a downward adjustment state.

[0017] Preferably, there are two bases, the bottoms of the bases are respectively mounted on both sides of the top of the vehicle body, and one side of the mounting frame is mounted on one side of the slewing reducer.

[0018] Preferably, a power assembly is installed on the top of the vehicle body, and the power assembly includes a hydraulic station, a pneumatic motor and an air compressor.

When the pipe diameter is large, it is convenient to reach the other side of the pipeline and install the bolts on the other side of the pipeline.

[0047] There are two bases 101, the bottoms of the bases 101 are respectively mounted on both sides of the top of the vehicle body 6, and one side of the mounting frame 109 is mounted on one side of the rotary reducer 38. Fig. 9 The rotary reducer 38 and the base 101 are in a vertical state, with an angle of ninety degrees.

[0048] Working principle: When it is necessary to install the pipeline in the coal mine, the worker first moves the vehicle body 6 to the side where the installation is required under the action of the operating platform 5, and then controls the push rod ends of the first hydraulic cylinder 4 and the second hydraulic cylinder 9 to extend through the second control valve 8, so that the push rod ends of the first hydraulic cylinder 4 and the second hydraulic cylinder 9 are supported on the ground respectively, increasing the stability between the vehicle body 6 and the ground, and then controls the pipe grasping mechanism 1 through the operating platform 5 to clamp the pipeline;

[0049] At this time, the workers enter the top of the front and rear bottom plates 31 respectively through the telescopic ladder 33, and are protected by the guardrail 36. Then, the push rod ends of the first oil cylinder 37, the second oil cylinder 102 or the third oil cylinder 107 are controlled to extend or retract through the first control valve 2, so that the bottom plate 31 is located at the specified position, and the output shaft of the rotary reducer 38 is controlled to rotate, so that the bottom plate 31 is in the left and right angle adjustment state;

[0053] In addition, the emergency stop button 32 and the air pipe connector 35 are arranged on the inner side of the workbench assembly 3, so that the power output can be cut off in time when danger occurs, and the air pipe connector 35 can be connected to other pneumatic equipment.

[0054] In summary, the workbench assembly 3 can realize self-leveling or fine-tuning under the operation of the first control valve 2, and under the action of the bracket assembly 10 and the first oil cylinder 37, it can be adjusted in any direction up and down, left and right, and front and back, so that workers can easily adapt to the pipeline installation requirements at different positions and angles, greatly improving the work efficiency;

[0055] The bottom plate 31 can be kept level to ensure that the center direction of the worker is always perpendicular to the bottom plate 31, reducing the fatigue of the workers caused by being in an unbalanced state for a long time and improving their work efficiency. Under the action of the second cylinder 102 and the third cylinder 107, the bottom plate 31 can increase the extension distance, and the workers can easily reach the other side of the pipeline and install the bolts on the other side of the pipeline, thereby solving the problem of installing large-diameter pipelines.

[0056] The workbench assemblies 3 are respectively arranged on the front and rear sides of the vehicle body 6, and workers can select any workbench assembly 3 to operate according to actual conditions, so that workers can use space and time more efficiently and quickly adapt to different working conditions, thereby improving overall work efficiency;

[0057] The emergency stop button 32 provided on the inner side of the workbench assembly 3 provides an emergency stop mechanism for the workers. When a dangerous situation occurs, the workers can quickly press the emergency stop button 32 to cut off the power output, thereby avoiding potential safety accidents, greatly enhancing the safety of the operation process, and providing additional protection for the workers.

[0058] The workbench assembly 3 can be connected to other pneumatic equipment through the air pipe joint 35. Workers can connect various pneumatic tools or equipment as needed to assist in completing tasks such as tightening pipeline connecting bolts and installing suspension ropes, thereby improving the practicality of the workbench assembly 3.
