[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 8 As shown, the utility model provides a modular power distribution network integrated power engineering vehicle, including an integrated power engineering vehicle body 1; a forklift structure frame 2, which is arranged on the front of the integrated power engineering vehicle body 1; a forklift lifting knife 3, which is arranged below the front of the forklift structure frame 2; a supporting slide plate 4, which is arranged on both sides of the bottom end of the forklift lifting knife 3; an adjustment component 5 includes an adjustment movable seat 501, the adjustment movable seat 501 is movably installed on the top of the supporting slide plate 4, and a slider 502 is fixedly installed on the bottom of the adjustment movable seat 501, and the forklift lifting knife 3 is fixedly installed on the bottom of the forklift lifting knife 3. A hydraulic linkage component 7 located below the middle of the adjustable movable seat 501 is provided at the bottom, a fixed plate 6 located inside the hydraulic linkage component 7 is fixedly installed between the bottoms of the forklift lifting knife 3, an inductive trigger component 8 located inside the hydraulic linkage component 7 is provided on the inner wall of the fixed plate 6, and a driving component 9 located inside the inductive trigger component 8 is provided on the inner wall of the fixed plate 6. When the equipment presses down the two adjustable movable seats 501 toward each other, the hydraulic linkage component 7 and the inductive trigger component 8 are activated, and the driving component 9 is used to drive them to the center.

[0033] When the equipment or object squeezes and pushes the two adjustable movable seats 501 to move away from each other, the two hydraulic piston rods 702 can be driven to move away from each other at the same time, so that the hydraulic piston cylinder 701 generates negative pressure and the hydraulic oil in the inner cavity of the induction hydraulic piston groove 801 is introduced into the inner cavity of the induction hydraulic piston groove 801 through the connecting hydraulic delivery channel 10, thereby driving the induction hydraulic piston push rod 802 to move toward each other.

[0034] like Figure 7 and Figure 8 As shown, there are two adjustable movable seats 501 , and the tops of the two adjustable movable seats 501 are both designed with inclined surfaces.

[0035] By adopting the above solution, through the inclined surface design on the top of the two adjustable movable seats 501, when the device applies downward pressure, the two adjustable movable seats 501 will be smoothly squeezed and pushed to move away from each other.

[0036] like Figure 7 and Figure 8 As shown, the slider 502 is slidably connected to the inner wall of the supporting slide rail plate 4 , and the size of the slider 502 is adapted to the inner wall of the supporting slide rail plate 4 .

[0037] With the above solution, a slider 502 is provided. When the movable seat 501 is adjusted to move, the slider 502 and the inner wall of the supporting rail plate 4 can smoothly move toward or away from each other horizontally.

[0038] like Figure 3 As shown, the hydraulic linkage assembly 7 includes a hydraulic piston cylinder 701, a hydraulic piston rod 702 and a first spring 703;

[0039] The hydraulic piston cylinder 701 is fixedly installed at the bottom of the forklift lifting knife 3 and the middle of the outer side of the fixed plate 6. The hydraulic piston rod 702 is movably sleeved in the inner cavity of the hydraulic piston cylinder 701. The outer end of the hydraulic piston rod 702 is fixedly connected to the bottom of the adjustable movable seat 501. The first spring 703 is fixedly installed on the outer side of the hydraulic piston rod 702.

[0040] By adopting the above scheme, a hydraulic piston rod 702 is provided. When the movable seat 501 is adjusted to drive the hydraulic piston rod 702 to move in opposite directions, negative pressure can be generated inside the hydraulic piston cylinder 701, so that the hydraulic oil in the induction trigger component 8 can be subsequently transported and introduced into the hydraulic piston cylinder 701.

[0041] like Figure 3 As shown, the other end of the first spring 703 is fixedly connected to the inner cavity of the hydraulic piston cylinder 701 .

[0042] By adopting the above scheme, a first spring 703 is provided. When the hydraulic piston rod 702 moves in opposite directions, the first spring 703 will be squeezed. When the opposite forces on the adjustable movable seat 501 and the hydraulic piston rod 702 are released, the first spring 703 will be released synchronously, which will push the two hydraulic piston rods 702 towards each other and drive the adjustable movable seat 501 to reset synchronously towards each other.

[0043] like Figure 5 As shown, the induction trigger assembly 8 includes an induction hydraulic piston groove 801 and an induction hydraulic piston push rod 802;

[0044] The induction hydraulic piston groove 801 is opened at the upper and lower sides of the inner wall of the fixed plate 6 , and the induction hydraulic piston push rod 802 is movably sleeved in the inner cavity of the induction hydraulic piston groove 801 .

[0045] By adopting the above scheme, an inductive hydraulic piston push rod 802 is provided. When the hydraulic oil in the inner cavity of the inductive hydraulic piston groove 801 is transported away by the negative pressure force generated by the hydraulic piston rod 702 in reverse, the inductive hydraulic piston push rod 802 will be driven to move to the opposite position.

[0046] like Figure 4 and Figure 5 As shown, the inner wall of the fixed plate 6 is provided with a hydraulic delivery channel 10 located between the inner side of the hydraulic piston cylinder 701 and the induction hydraulic piston push rod 802, and the two ends of the hydraulic delivery channel 10 are respectively connected to the inner side of the hydraulic piston cylinder 701 and the inner side of the top end of the induction hydraulic piston push rod 802.

[0047] By adopting the above scheme, a connecting hydraulic delivery channel 10 is provided. When the hydraulic piston rods 702 move in opposite directions, negative pressure will be generated in the hydraulic piston cylinder 701, and the hydraulic oil in the inner cavity of the sensing hydraulic piston groove 801 will be introduced into the hydraulic piston cylinder 701 through the connecting hydraulic delivery channel 10, so that the hydraulic piston cylinder 701 can move smoothly.

[0048] like Figure 5 and Figure 6 As shown, the driving assembly 9 includes a driving motor 901, a driving rotating shaft 902 and an induction adjustment rotating plate 903;

[0049] The driving motor 901 is fixedly installed at the middle of the back side of the fixed plate 6 , the driving rotating shaft 902 is fixedly installed at the output end of the driving motor 901 , and the induction adjustment rotating plate 903 is fixedly sleeved on the surface of the front end of the driving rotating shaft 902 .

[0050] By adopting the above scheme, an inductive adjustment rotating plate 903 is provided. When the upper end or the lower end of the inductive adjustment rotating plate 903 is pressed against and deflected by the inductive hydraulic piston push rod 802, the driving motor 901 can be started at this time, so that the driving rotating shaft 902 drives the inductive adjustment rotating plate 903 to rotate and reset, so that the moving distance of the inductive hydraulic piston push rod 802 towards each other remains consistent.

[0051] like Figure 3 and Figure 8 As shown, a clamping assembly 11 is disposed in the middle of the inner cavity of the adjusting movable seat 501, and the clamping assembly 11 includes a telescopic clamping block 1101, a limiting sliding block 1102 and a second spring 1103;

[0052] The telescopic clamping block 1101 is movably installed in the middle of the inner wall of the adjustable movable seat 501, the limiting sliding block 1102 is fixedly installed in the middle of both sides of the telescopic clamping block 1101, and the second spring 1103 is fixedly installed between the bottom of the telescopic clamping block 1101 and the inner wall of the adjustable movable seat 501.

[0053] By adopting the above scheme, a second spring 1103 is provided. When the telescopic clamping block 1101 is squeezed toward each other, the second spring 1103 will be squeezed synchronously. When the telescopic clamping block 1101 is released, the second spring 1103 can be released, thereby pushing the telescopic clamping block 1101 to reset upward.

[0054] like Figure 3 and Figure 8 As shown, there are four limit sliding blocks 1102 , and the four limit sliding blocks 1102 have the same size.

[0055] By adopting the above scheme, a limit sliding block 1102 is set. When the telescopic clamping block 1101 is squeezed downward or pushed upward by the elastic force of the second spring 1103, the limit sliding block 1102 will slide and limit on the inner wall of the adjusting movable seat 501, so that the telescopic clamping block 1101 as a whole can smoothly move up and down vertically.

[0056] The working principle and use process of this utility model:

[0057] First, when the device is lifted, the device will squeeze the top inclined surfaces of the two adjustable movable seats 501 to drive the two adjustable movable seats 501 to move away from each other. When the device squeezes downward, it will push the telescopic clamping block 1101 to retract downward to the inner cavity of the adjustable movable seat 501, so that the adjustable movable seat 501 moves away from each other. When the telescopic clamping block 1101 is to the outside of the device, the elastic force of the second spring 1103 will be released, and the two telescopic clamping blocks 1101 will be smoothly pushed upward, so that the two sides of the device can be quickly clamped.

[0058] Afterwards, since the equipment is not centered, the adjustment movable seat 501 will move away from each other at unequal distances, and will then drive the hydraulic piston rod 702 to move away from each other at different distances, so as to generate negative pressure and introduce the hydraulic oil in the induction hydraulic piston groove 801 into the hydraulic piston cylinder 701 through the connecting hydraulic delivery channel 10, thereby causing the two induction hydraulic piston push rods 802 to move towards each other at different distances, and then the extended long end will push the induction adjustment rotating plate 903 and the driving rotating shaft 902 to idle, and then the driving motor 901 can be started. Since the operation of the driving motor 901 will cause the driving rotating shaft 902 to drive the induction adjustment rotating plate 903 to rotate and reset, finally the moving distances of the two induction hydraulic piston push rods 802, the hydraulic piston cylinder 701, and the adjustment movable seat 501 remain the same, so that the equipment can be quickly centered.

[0059] Then, after the support for the equipment is released, the elastic force of the first spring 703 will be released, so as to smoothly drive the two hydraulic piston rods 702 and the adjustable movable seat 501 to reset toward each other. At the same time, the hydraulic oil in the hydraulic piston cylinder 701 can be guided back to the inside of the induction hydraulic piston groove 801 through the connecting hydraulic delivery channel 10, and finally the two induction hydraulic piston push rods 802 can be driven to move away from each other for reset.
