[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Please refer to Figs. 1 to 3 The utility model provides a kind of technical scheme: a pipe gallery lifting appliance with hydraulic system, including two installation plate 1 and the hydraulic pole 2 of fixed connection in installation plate 1 bottom, two installation plate 1 is arranged in left side and right side respectively, the bottom end of hydraulic pole 2 is equipped with the adjusting structure for automatic balance.

[0025] As Fig. 1 As shown, adjusting structure includes fixed plate 3 fixedly connected to the bottom end of hydraulic pole 2, hinged seat 4 fixedly connected to the bottom of fixed plate 3, connecting piece 5 hinged to the front and rear two side walls in hinged seat 4 and support frame 6 fixedly connected between the bottom of left and right two connecting pieces 5.

[0026] The inner side of support frame 6 is provided with an auxiliary assembly for improving the stability of pipeline, and the auxiliary assembly comprises elastic expansion pieces 9 fixedly connected to the inner front side wall and the inner rear side wall of support frame 6 respectively, and clamping plates 10 fixedly connected to opposite ends of the front and rear two elastic expansion pieces 9 respectively.

[0027] It should be noted that the number of left and right two hydraulic poles 2 is three, and the three hydraulic poles 2 on the same side are arranged equidistantly along the left-right direction of installation plate 1, to ensure that the stress of support frame 6 is uniform, to avoid structural deformation or instability caused by excessive stress at a single point, and the three hydraulic poles 2 on the same side are arranged in parallel, and the three hydraulic poles 2 on the same side are connected in parallel through hydraulic circuit, to ensure that the pressure and flow of hydraulic oil are evenly distributed, so as to realize synchronous expansion and contraction. This design not only improves the carrying capacity of the system, but also enhances the overall stability. In addition, when a single hydraulic pole fails, the remaining hydraulic poles can still maintain system operation, providing redundancy protection.

[0028] An inclination sensor 7 is fixedly connected to the center of the top of support frame 6, which can monitor the left and right inclination angles of support frame 6 in real time, and provide accurate attitude data for automatic balance control. The inclination sensor 7 is built-in with filter software, which can be Kalman filter or low-pass filter, to eliminate noise caused by mechanical vibration or external interference, and ensure that the angle data output by the sensor is stable and reliable.

[0029] The inner top wall and the inner bottom wall of the support frame 6 are fixedly connected with rubber pads 8, and the length and width of the rubber pads 8 are equal to the length and width of the inside of the support frame 6 respectively. The elastic properties of the rubber pads 8 can effectively absorb the energy generated by the pipeline due to vibration or impact, reduce the impact on the support frame 6 and the hydraulic system, and prolong the service life of the equipment.

[0030] The number of the front and rear elastic expansion pieces 9 is nine, and the nine elastic expansion pieces 9 on the same side are arranged equidistantly along the front and rear directions of the support frame 6 in turn. The arrangement of the plurality of elastic expansion pieces 9 forms a multi-point support structure, further enhancing the stability of the pipeline in the front and rear directions, and ensuring that the stress on the pipeline in the front and rear directions is uniform.

[0031] The clamping plate 10 is an arc-shaped plate, which matches the shape of the outer wall of the pipeline, ensures that the clamping force is uniformly distributed, and avoids local stress concentration. The inner side wall of the clamping plate 10 is provided with anti-skid lines, which increase the friction force with the surface of the pipeline, prevent the pipeline from sliding or falling off during clamping, and the surface of the support frame 6 and the surface of the clamping plate 10 are coated with an anti-corrosion coating. The anti-corrosion coating can be an epoxy resin or a polyurethane coating, which can effectively resist the erosion of moisture, corrosive gas or liquid, and prolong the service life.

[0032] The working principle of the above embodiment is as follows:

[0033] The inclination sensor 7 monitors the inclination angle of the support frame 6 in real time and transmits the data to the control system. The control system calculates the current inclination angle and the target angle after receiving the data. If the support frame 6 tilts to the left, the control system shortens the left hydraulic rod 2 or lengthens the right hydraulic rod 2. If it tilts to the right, it adjusts in the opposite direction. By differential extension and contraction of the left and right hydraulic rods 2, the support frame 6 returns to the horizontal state. The inclination sensor 7 continuously monitors the posture of the support frame 6, and the control system continuously optimizes the adjustment amount of the hydraulic rod 2 according to the feedback data until the support frame 6 reaches the balance state.

[0034] To strengthen the stability of the pipeline, the elastic expansion piece 9 adjusts the clamping force according to the vibration or displacement state of the pipeline. When the pipeline vibrates due to external impact or internal fluid flow, the elastic expansion piece 9 absorbs vibration energy through extension and contraction, reducing the impact on the support frame 6. At the same time, the arc-shaped design and anti-skid lines of the clamping plate 10 that clamps the pipeline increase the friction force with the surface of the pipeline, ensuring that the pipeline will not slide or fall off during clamping.

[0035] The electrical components appearing in the text are electrically connected with the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing disclosed power connection technology is not described in detail.
