Description

Technical Field

[0001] This invention relates to the field of substation auxiliary equipment technology, and in particular to a stable support device for power emergency repair vehicles. Background Technology

[0002] Power grid emergency repair vehicles are specialized vehicles designed for the maintenance and repair of power grid systems. Their core function is to carry repair personnel, tools, and materials to the fault site quickly to carry out operations. For example, when a power grid emergency repair vehicle's boom lift is performing high-altitude operations, it needs to extend its boom or lifting platform. To ensure the vehicle's stability, it needs to be supported. This typically involves selecting and operating the outriggers to extend horizontally. After the horizontal outriggers are in place, the vertical outriggers are extended downwards, contacting the ground for support, thus preventing the vehicle from shifting. However, when existing power grid emergency repair vehicles are performing high-altitude operations in loose soil, the vertical outriggers are in direct contact with the ground, making the vehicle prone to losing balance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a stable support device for power emergency repair vehicles, which can enhance the support stability of power emergency repair vehicles in loose soil terrain, further improve the safety of operations; the structure is simple and easy to repair and maintain.

[0034] Before using the vehicle, first control the hydraulic rod 6 to move the push block 5. The push block 5 drives the crossbeam 4 to move, which facilitates the crossbeam 4 to control the left and right movement of the contact pad 77. Then control the hydraulic cylinder 71 to drive the bottom rod 74 to descend. The bottom rod 74 drives the fixing cylinder 75 to descend. The fixing cylinder 75 drives the contact pad 77 to descend, so that the contact pad 77 contacts the ground, which facilitates the support of the vehicle. Before support, fill the loose soil with stones through the filling component 8 to facilitate support.

[0035] Furthermore, the outward support assembly also includes: a lifting groove 720 formed on the upright plate 719, a lifting block 721 installed in the lifting groove 720, a pressure block 722 connected to one end of the lifting block 721, and a second hinge block 725 hinged between the adjusting plate 716 and the linkage plate 724, wherein: the other end of the lifting block 721 is connected to the first hinge block 723.

[0036] The fixed cylinder 75 has a fixed ring 726 at the bottom and a pressure ring 727 at the top. The pressure ring 727 drives the pressure block 722 to descend. Multiple uprights 728 are mounted on the fixed ring 726. A first spring 729 is installed between the pressure ring 727 and the fixed ring 726. The pressure ring 727 is slidably connected to the uprights 728.

[0037] Furthermore, a bottom cylinder 732 is connected to the bottom of the fixed cylinder 75, and an air inlet pipe 733 is connected to the outside of the bottom cylinder 732. A first one-way valve 734 is provided on the outside of the air inlet pipe 733. An air supply pipe 736 is connected to one end of the bottom cylinder 732. The air supply pipe 736 is installed in the mounting cavity 735 provided on the inside of the fixed cylinder 75. A second one-way valve 745 is provided in the air supply pipe 736. An air storage tank 738 is installed on the outside of the bottom rod 74. An output pipe 737 is installed between the air storage tank 738 and the air supply pipe 736. A first fixing plate 72 is installed on the outer side of the base rod 74, and a vertical cylinder 741 is installed at the bottom of the first fixing plate 72. A first piston disc 742 is installed in the vertical cylinder 741, and a connecting rod 743 is connected to one end of the first piston disc 742. An exhaust valve 744 is provided on the outer side of the vertical cylinder 741. A connecting pipe 739 is installed between the gas storage tank 738 and the vertical cylinder 741, and a solenoid valve 740 is installed on the connecting pipe 739.

[0038] Preferably, a push rod 730 is connected to the top of the contact pad 77, and a second piston disc 731 is connected to the top of the push rod 730. The second piston disc 731 is sealed and connected in the bottom cylinder 732. When the contact pad 77 moves up and down, the contact pad 77 moves up and down in conjunction with the push rod 730 and the second piston disc 731, so that the gas drawn in by the air inlet pipe 733 is stored in the air storage tank 738 through the outlet pipe 737.

[0039] Preferably, the gas in the gas storage tank 738 is discharged into the vertical cylinder 741 through the connecting pipe 739 by controlling the solenoid valve 740. The gas pushes the first piston disc 742 to link the connecting rod 743. The connecting rod 743 is connected to the pressure ring 727 of the fixed cylinder 75.

[0040] During implementation, when the contact pad 77 moves up and down, the contact pad 77 drives the push rod 730 to move up and down, and the push rod 730 drives the second piston disc 731 to move up and down. When the second piston disc 731 descends, the external airflow enters the bottom cylinder 732 through the first one-way valve 734 on the air inlet pipe 733. When the second piston disc 731 rises, the drawn-in airflow is delivered to the outlet pipe 737 through the second one-way valve 745 and the air delivery pipe 736, and the airflow is stored through the air storage tank 738. The air delivery pipe 736 is made of flexible hose material. When the stone is compacted, the contact pad 77 comes into contact with the stone.

[0041] During this process, the solenoid valve 740 is controlled to discharge the gas in the gas storage tank 738 and deliver the gas to the vertical cylinder 741 through the connecting pipe 739. The gas pushes the first piston disc 742 down, the first piston disc 742 drives the connecting rod 743 down, the connecting rod 743 drives the pressure ring 727 down, the pressure ring 727 contacts the pressure block 722 when it descends, as the pressure ring 727 descends, the pressure ring 727 drives the pressure block 722 down, the pressure block 722 drives the lifting block 721 down, the lifting block 721 drives the linkage plate 724 to rotate.

[0042] At the same time, the linkage plate 724 drives the adjustment plate 716 to rotate, and the adjustment plate 716 drives the spikes 718 on the extension plate 717 to rotate, causing multiple extension plates 717 to expand outward, and the spikes 718 to contact the ground and insert into the soil, further increasing the contact area with the soil and improving the support effect.

[0043] Furthermore, the filling component 8 also includes: a baffle 814 installed in the material guide channel 87, a rectangular plate 815 connected to the baffle 814, and an electric push rod 816 installed between the rectangular plate 815 and the material guide channel 87, wherein: by controlling the electric push rod 816 to move the rectangular plate 815 and the baffle 814, the stone on the hopper 813 falls into the material guide channel 87.

[0044] During implementation, stones are poured into the hopper 813. Before support is provided, the vehicle is moved. At this time, the electric push rod 816 is controlled to move the rectangular plate 815. The rectangular plate 815 moves the baffle 814. Under the action of gravity, the stones on the hopper 813 fall into the guide channel 87, and the filling cylinder 83 lays the stones on the loose soil, improving the vehicle support effect.

[0045] Preferably, the bottom of the crossbeam 4 is connected to a base block 84 and a base frame 89 respectively. A telescopic rod 85 and a second spring 86 are connected between the base block 84 and the packing cylinder 83. A rotatable control rod 810 is installed on the base frame 89. A cam 811 is installed on the control rod 810. A drive motor 812 for driving the control rod 810 to rotate is installed at the bottom of the base frame 89.

[0046] During implementation, when processing ordinary materials, the drive motor 812 is started. The drive motor 812 drives the control lever 810 to rotate, the control lever 810 drives the cam 811 to rotate, and the cam 811 drives the packing cylinder 83 to move left and right, so that the stone material discharged from the packing cylinder 83 is laid more evenly. At the same time, it shakes left and right, so that the stone material discharge in the hopper 813 is smoother.

[0047] In the specific implementation of the stabilizing support device for power emergency repair vehicles in this embodiment of the invention, firstly, workers pour stones into the hopper 813, control the hydraulic rod 6 to move the crossbeam 4, and control the filling cylinder 83 to move. When it reaches the vicinity of loose soil, control the electric push rod 816 to move the baffle 814 on the rectangular plate 815, so that the stones pass through the guide channel 87 and the filling cylinder 83, and are laid on the loose soil. At the same time, start the drive motor 812 to control the cam 811 to rotate, and control the filling cylinder 83 to move left and right, so that the stones are evenly laid on the soil. Then, control the hydraulic cylinder 71 to drive the contact pad 77 to descend, so that the contact pad 77 contacts the stones.

[0048] Under the action of the reciprocating rod 76, the contact pad 77 moves up and down, facilitating the compaction of the stone by the contact pad 77 and increasing the stability of the vehicle support. During compaction, the contact pad 77 drives the second piston disc 731 on the push rod 730 to move up and down, and under the action of the air intake pipe 733, the first one-way valve 734, the air delivery pipe 736, and the second one-way valve 745, gas is injected into the air tank 738.

[0049] Further control of the solenoid valve 740, under the action of the connecting pipe 739 and the vertical cylinder 741, pushes the connecting rod 743 on the first piston disc 742 to descend. The connecting rod 743 drives the pressure ring 727 to descend, causing the pressure ring 727 to descend against the pressure block 722. Under the action of the lifting block 721, the linkage plate 724 and the adjusting plate 716, control the spikes 718 on the extension plate 717 to rotate, so that the spikes 718 on multiple extension plates 717 are inserted into the soil. The extension plate 717 partially contacts the ground, further improving the support effect. When not providing support, control the exhaust valve 744 to release the gas in the vertical cylinder 741, facilitating the reset of the extension plate 717.
