Description

Technical Field

[0001] This utility model belongs to the field of vehicle-mounted electric outriggers, specifically, it relates to an electric outrigger for vehicles. Background Technology

[0002] Vehicle-mounted electric outriggers are electrically driven support devices installed on engineering vehicles or special-purpose vehicles (such as fire trucks, cranes, aerial work platforms, and emergency rescue vehicles). Their core function is to quickly and stably support the vehicle body before or during operation, significantly enhancing vehicle stability and ensuring operational safety.

[0003] Currently, when using vehicle-mounted outriggers, the vehicle needs to be driven to a flat (or nearly flat) area to ensure contact between the chassis and the ground and to ensure stability during the lifting process. However, when using them on uneven or sloping surfaces, the concave surface needs to be filled in before they can be used, which increases the workload and affects efficiency. Utility Model Content

[0004] To address the above deficiencies, this utility model provides an electric outrigger for vehicles, including an electric push rod for raising and a support plate for grounding. The top of the support plate is provided with a ball joint groove, and a matching ball joint is installed inside the ball joint groove. The ball joint is fixedly connected to the telescopic end of the electric push rod.

[0005] The outer surface of the electric push rod is fixed with a collar by screws. The outer ring of the collar has a sliding groove, and a matching slider is slidably connected in the sliding groove. The end of the slider away from the collar is fixed with an auxiliary support mechanism to form a triangle between the electric push rod and the ground.

[0006] Furthermore, the auxiliary support mechanism includes a positioning block welded to the slider, and the positioning block is hinged by a pin to an auxiliary support plate for contacting the ground.

[0007] Furthermore, the auxiliary support plate is a telescopic structure, and an inner plate is movably connected to the slot inside the auxiliary support plate. The inner plate has equidistantly arranged positioning holes, and the bottom of the auxiliary support plate has insertion holes that match the positioning holes. The extension length of the inner plate is limited by inserting bolts.

[0008] Furthermore, the bottom end of the inner plate is provided with an outward end, and the outward end is hinged to a bottom plate by a pin. The bottom plate has a ground anchor hole for inserting a ground anchor.

[0009] Furthermore, the support mechanism also includes a crossbar, one end of which is welded with a retaining ring that fits against the outer surface of the telescopic end, and the other end of which is welded with a protrusion for insertion into a positioning hole.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The ball joint structure enables stable contact (support) between the support plate and the slope surface, providing good bottom support when the electric push rod is raised and lowered. At the same time, the support mechanism is used to form a triangle between the electric push rod, the road surface and the support mechanism, thereby increasing the overall stability.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example

[0020] like Figures 1 to 5 As shown, this embodiment provides an electric outrigger for a vehicle, including an electric push rod 1 for raising and a support plate 4 for grounding. The top of the support plate 4 is provided with a ball joint groove, and a matching ball joint 3 is installed inside the ball joint groove. The ball joint 3 is fixedly connected to the telescopic end 2 of the electric push rod 1, thereby realizing the function of stable support by rotating the ball joint 3 in the ball joint groove and contacting the slope ground.

[0021] To provide more stable support and facilitate use by large vehicles, the following structures were added:

[0022] The outer surface of the electric push rod 1 is fixed with a collar 51 by screws. The outer ring of the collar 51 has a groove 52. A matching slider 6 is slidably connected in the groove 52. It should be noted that the structure of the slider 6 and the groove 52 is a traditional T-shaped snap-fit ​​structure, which will not be described in detail here. The end of the slider 6 away from the collar 51 is fixed with an auxiliary support mechanism 7 for forming a triangle between the electric push rod 1 and the ground.

[0023] In detail, the auxiliary support mechanism 7 includes a positioning block 71 welded to the slider 6. The positioning block 71 is hinged to an auxiliary support plate 72 for contacting the ground via a pin. When providing slope support, the position of contact with the ground can be adjusted by rotation, thereby achieving the function of adapting to different road surfaces.

[0024] The auxiliary support plate 72 can also be designed as a telescopic structure to accommodate the longer telescopic range of the electric push rod 1. The slot inside the auxiliary support plate 72 is movably connected to the inner plate 73. The inner plate 73 has equidistantly arranged positioning holes 76. The bottom of the auxiliary support plate 72 has an insertion hole that matches the positioning holes 76. After the bolt 74 is inserted, the extension length of the inner plate 73 is limited.

[0025] The bottom end of the inner plate 73 is provided with an outward end to prevent the inner plate 73 from being fully inserted into the slot, so as to facilitate subsequent pulling out. The outward end is hinged to a base plate 75 by a pin to increase the contact area with the ground. The base plate 75 has a ground anchor hole 77 for inserting a ground anchor. By inserting a ground anchor, a more stable positioning and support effect can be achieved.

[0026] Additionally, the support mechanism 7 also includes a crossbar 10. One end of the crossbar 10 is welded with a retaining ring 11 that fits against the outer surface of the telescopic end 2. The other end of the crossbar 10 is welded with a protrusion 12 for inserting into the positioning hole 76. Its function is to increase the connection strength between the auxiliary support mechanism 7 and the electric push rod 1. It should be noted that, in order to facilitate the fitting of the retaining ring 11, the annular length of the retaining ring 11 should be less than half the circumference of the telescopic end 2.

[0027] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
