Abstract
Description
Technical Field
[0001] This application relates to the field of building construction technology, and in particular to a vehicle engineering support device. Background Technology
[0002] In engineering vehicles such as concrete pump trucks and truck cranes, outriggers are generally used to increase support strength in order to prevent excessive stress on the vehicle tires or to prevent overturning, and support stability is improved by increasing the longitudinal and lateral support spans of the vehicle body.
[0003] Chinese utility model patent CN219769850U discloses a box-shaped pad suitable for outriggers of engineering vehicles, including a box body with a bottom opening and a bottom plate for covering the bottom opening of the box body. Multiple parallel support rods are fixedly installed inside the box body. The top of the support rods is connected to the box body, and the bottom of the support rods is connected to the bottom plate. A connecting rod is fixedly installed between any two adjacent support rods. Lifting lugs are provided on opposite sides of the box body.
[0004] While the aforementioned patent boasts strong pressure resistance and facilitates suspension and movement, it suffers from the following drawbacks:
[0005] 1. The number and angle of the internal support rods and connecting rods of the housing result in multiple welding points, increasing manufacturing costs and potential failure points.
[0006] 2. In actual use, concrete pump trucks at the pouring site usually do not have hoisting equipment to lift the base plate, and their existing structure is not convenient for manual movement. Utility Model Content
[0007] Therefore, it is necessary to provide a vehicle engineering support device to overcome the defects mentioned in the background art.
[0008] A vehicle engineering support device includes hydraulic outriggers and a base plate. The base plate has a support structure inside, the bottom of which abuts against the bottom of the base plate, and its end is detachably connected to the side wall inside the base plate. The end of the base plate has a connection hole, and an extension rod is detachably connected to the connection hole.
[0009] As a preferred embodiment of the vehicle engineering support device of this utility model, the pad includes a box with a bottom opening and a base plate for covering the bottom opening of the box.
[0010] As a preferred embodiment of the vehicle engineering support device of this utility model, the box body is provided with an expansion connecting block, and the expansion connecting block is provided with an expansion hole at the position corresponding to the connecting hole.
[0011] As a preferred embodiment of the vehicle engineering support device of this utility model, the support structure includes cross steel sections, triangular cross trusses, or X-shaped cross trusses.
[0012] As a preferred embodiment of the vehicle engineering support device of this utility model, one end of the extension rod is detachably connected to the extension connecting block, and the other end is provided with a lifting ring or lifting rod.
[0013] As a preferred embodiment of the vehicle engineering support device of this utility model, it also includes a cover plate for covering the connection hole.
[0014] The beneficial effects of this utility model are:
[0015] This utility model makes it more suitable for construction sites by setting up extension rods. By replacing different extension rods, it can be used for different working conditions such as hoisting and manual handling, making it easy to move to the designated location.
[0016] The support structure in this invention is detachably connected to the side wall of the box, and its load-bearing surface abuts against the box and the bottom plate. There are no welding points, thus reducing the number of failure points. Attached Figure Description

[0041] In this embodiment, one end of the extension rod 2000 is provided with an external thread, which is detachably connected to the extension connection hole on the extension connection block 5000. The other end is at least of two types, such as... Figure 3 and Figure 4 As shown, it includes a lifting rod and lifting rings. The lifting rings are used when lifting the pad, and the lifting rod is used when manually moving the pad.
[0042] In this embodiment, a cover plate for blocking the connection hole is also included, the cover plate as follows: Figure 5 As shown.
[0043] Example 2
[0044] The difference between this embodiment and Embodiment 1 is that the base plate 4000 is provided with multiple detachable support legs. The length of the support legs can be adjusted to adapt to a bottom inclination of ±15 degrees, so as to facilitate the deployment of the support legs on uneven ground.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
