The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and provides an electric leg outrigger device, which includes a bracket 100, which is installed on a trolley by bolts, and includes a fixing member 101, and the fixing member 101 is arranged on the side of the bracket 100; a support assembly 200, which is connected to the side wall of the bracket 100, includes a leg 201 and a lifting member 202, and the lifting member 202 is arranged on the side wall of the leg 201;

[0030] The bracket 100 is installed directly above the trolley, the fixing member 101 can fix the supporting assembly 200 when it is stored and unfolded, the legs 201 are used to support the trolley and the bracket 100, and the lifting member 202 is used to lift and lower the trolley.

[0031] Example 2

[0032] Reference Figure 2 to Figure 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0033] Specifically, four ends of the bracket 100 are provided with joints 100 a .

[0034] Specifically, the leg 201 includes a connecting frame 201a, a mounting sleeve 201b, an outer leg 201c, an inner leg 201d, and a pin 201e. One end of the connecting frame 201a is hinged to the joint 100a through the pin 201e, and the other end is fixedly connected to the mounting sleeve 201b. The mounting sleeve 201b is fixed on the outer leg 201c, and the inner leg 201d slides with the inner wall of the outer leg 201c.

[0035] Specifically, the fixing member 101 includes a fixing block 101a and a clamping block 101b, wherein the clamping block 101b is slidably disposed in the fixing block 101a; a limiting axis 101c is disposed at the end of the fixing block 101a; the lower end of the clamping block 101b is slidably engaged with the limiting axis 101c, a spring 101d is disposed between the clamping block 101b and the end of the fixing block 101a, and inclined surfaces 101e are disposed on both sides of the upper end of the clamping block 101b.

[0036] Specifically, a side wall of the connecting frame 201a is provided with a card slot 101f.

[0037] In the initial state, the outer leg 201c is in contact with the side wall of the bracket 100. At this time, the block 101b is located in the slot 101f, and the spring 101d is at its original length. The outer leg 201c is pulled to make the connecting frame 201a rotate on the bracket 1 through the pin 201e. When the connecting frame 201a moves, it will detach from the fixed block 101a through the slot 101f. At this time, the block 101b is pushed into the fixed block 101a, and the block 101b slides on the limit shaft 101c and squeezes the spring 101d, so that the connecting frame 201a can be detached smoothly.

[0038] Specifically, the fixing member 101 also includes a limit plate 102, a limit block 103 and an insertion rod 104. The limit plate 102 is arranged on the outside of the joint 100a, and the limit block 103 is arranged on the side wall of the connecting frame 201a; an opening 102a is arranged on the limit plate 102; the limit block 103 can be plugged into the opening 102a; the insertion rod 104 can be plugged into the limit block 103, and a convex plate 104a is arranged above it.

[0039] After the connecting frame 201a is opened to contact with the limiting plate 102, the limiting block 103 is plugged into the opening 102a, and the staff then inserts the insertion rod 104 into the limiting block 103. The convex plate 104a is used to limit the insertion rod 104. At this time, the connecting frame 201a is stuck and fixed.

[0040] Specifically, a connection block 201h and an installation connection plate 201f are provided at the upper end of the inner leg 201d, and the installation connection plate 201f is fixed to the side wall of the connection block 201h.

[0041] Specifically, the lifting member 202 includes an electric push rod 202a, a hinge block 202b, a first rotating shaft 202c, and a second rotating shaft 202d. The hinge block 202b is arranged at one end of the electric push rod 202a, and the hinge block 202b is hinged to the mounting sleeve plate 201b through the first rotating shaft 202c. The other end of the electric push rod 202a is hinged to the mounting connecting plate 201f through the second rotating shaft 202d.

[0042] Specifically, a foot 201g is further provided at the lower end of the inner leg 201d.

[0043] The electric push rod 202a is driven to retract by remote control. At this time, the top of the electric push rod 202a will move downward through the upper hinge block 202b and the first rotating shaft 202c. The connecting plate 201b is installed to drive the inner leg 201d to move downward through the connecting block 201h, so that the support leg 201g falls on the pad placed on the ground, and the position of the pad is adjusted to ensure that the support leg 21g will not slide out of the pad during the lifting process of the vehicle body. At this time, the bracket 100 will lift the vehicle as a whole.

[0044] During use, when the trolley needs to be moved up and down by a pickup truck, when the trolley is on the ground, make sure that there is no operating device (grounding mechanism, wire stripper, recovery mechanism, etc.) on the trolley body. First, move the trolley to a relatively flat ground by remote control, and move the pickup truck to the position of the trolley, so that the rear bucket of the pickup truck is aligned with the trolley. Then open the support assembly 200 and fix it, and lift the lower vehicle to a distance higher than the distance from the rear bucket of the pickup truck to the ground through the lifting member 202. Then the pickup truck reverses so that the entire vehicle and the track completely enter the rear bucket of the pickup truck, and then the tailgate is closed. At this time, the electric push rod 202a is controlled to extend and the inner leg 201d is retracted. Finally, the staff pulls the insertion rod 104 upward through the convex plate 104a to release the fixation of the connecting frame 201a, and then pushes the connecting frame 201a to the side of the bracket 100 for storage, so that the connecting frame 201a is plugged into the fixing block 101a through the slot 101f, and the block 101b will enter the connecting frame 201a and pop out, limiting the connecting frame 201a on the side of the bracket 100. After the storage is completed, the vehicle can be transported.

[0045] When the equipment is installed on a pickup truck, the support assembly 200 is first unfolded, and then the inner leg 201d is lowered to make the support foot 201g contact the pad on the ground, thereby raising the vehicle body, and then the pickup truck is moved forward to leave the vehicle body, and then the vehicle body is lowered.

[0046] When the trolley drives under the operating cable during the operation, the support assembly 200 is opened in the above manner to adjust the level of the vehicle body. It is worth mentioning that a level bubble can be set on the outer leg 201c, and the level of the vehicle body can be confirmed by observing the level bubble on the vehicle body. After the level adjustment is completed, subsequent work can be carried out. After the operation is completed, the support assembly 200 can be stored.

[0047] Example 3

[0048] Reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, provides a method for using an electric leg support device, comprising the following steps:.

[0049] Install the bracket on top of the trolley with bolts;

[0050] When the trolley is on the ground and needs to be transported to the pickup truck, move the pickup truck to the position of the trolley, align the rear bucket of the pickup truck with the trolley, and open the support components at the four corners in a radial shape;

[0051] The remote control drives the electric push rod, and the bracket lifts the whole car to a height higher than the distance from the rear bucket of the pickup truck to the ground;

[0052] The pickup truck reverses to make the trolley and the tracks completely enter the rear bucket of the pickup truck, and the electric push rod is controlled to make the trolley fall into the rear bucket, and then the support assembly is folded up to complete the storage;

[0053] When the trolley is getting off the pickup truck, it first unfolds the support assembly, then lowers the inner legs so that the legs come into contact with the pads on the ground, thereby raising the vehicle body, then moves the pickup truck forward and away from the vehicle body, and then lowers the vehicle body.
