Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, and in particular to a support foot capable of supporting uneven ground. Background Art

[0002] When medium and large machinery is working on unpaved roads, outriggers are an indispensable part of medium and large machinery and equipment. Although there are many types and forms, each form of outrigger has its own focus and shortcomings. Conventional outriggers are prone to unstable support due to uneven ground and other reasons, which has a very serious impact on production safety and production efficiency. Outriggers with simple structures are not adaptable to the ground, while outriggers with strong ground adaptability often have the disadvantages of complex structure, high cost, difficulty in manufacturing and installation, and high maintenance cost.

[0003] To this end, developing a support leg structure that can not only cope well with complex situations such as uneven non-paved road surfaces, but also achieve a good balance between environmental adaptability, structural strength, cost and manufacturing and installation difficulty is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] The present invention aims to overcome the deficiencies of the prior art and provide a support foot capable of supporting uneven ground.

[0005] In order to achieve the above object, the technical solution provided by the present invention is:

[0006] The support leg capable of supporting an uneven ground comprises a seat plate (1), a pair of parallel support plates (2) being vertically arranged on the top surface of the seat plate (1), the upper parts of the two support plates (2) being each provided with a first connection hole, a cross connection block (3) being arranged between the two support plates (2), the cross connection block (3) being provided with a connection channel and an axial hole (4) penetrating the cross connection block (3), the connection channel and the axial hole (4) being vertical, a rotating pin shaft (5) being arranged in the axial hole (4), the rotating pin shaft (5) being radially provided with a second connection hole, and the support plate (2) and the cross connection block (3) being connected by a bolt structure penetrating the first connection hole, the connection channel, and the second connection hole.

[0007] Preferably, a plate rib (6) is provided between the two support plates (2), and the bottom surface of the plate rib (6) is connected to the seat plate (1).

[0008] Preferably, the seat plate (1), the support plate (2) and the plate ribs (6) are integrally formed.

[0009] Preferably, both ends of the seat plate (1) are provided with bent portions bent upwards.

[0010] Preferably, the bolt structure comprises a long bolt (7) passing through the first connection hole, the connection channel and the second connection hole, and a nut (8) is provided at the tail end of the long bolt (7).

[0011] Preferably, a gasket (9) is provided between the end of the long bolt (7) and the contact surface of the support plate (2).

[0012] The present invention will be further described below:

[0013] The support leg capable of supporting uneven ground is mainly composed of a seat plate, a support plate, plate ribs, a rotating pin, a cross connection block, a long bolt and its matching nuts and gaskets.

[0014] There is an installation space between the two support plates on the seat plate. The upper part of the installation space is a cross connection block. The long nut passes through the support plate, the cross connection block and the rotating pin, thereby forming a stable support leg structure. The support leg can ensure the safety and reliability of the structure when subjected to forces in all directions. On the other hand, the support leg can be adjusted arbitrarily in two degrees of freedom, front, back, left and right, with the cross connection block as the core, to meet the support needs of the legs in different directions and better adapt to the support needs of different road surfaces. The main body of the machine is connected to both ends of the rotating pin of the support leg to form a flexible, simple and reliable structure, which effectively meets the needs of the equipment for stable ground support on uneven ground during operation.

[0015] The plate ribs at the bottom of the installation space can be used as reinforcing ribs, and the integrally formed seat plate, support plate and plate ribs can further improve the strength of the support legs; the present invention provides a first connection hole on the support plate, a connection channel on the cross connection block, and a second connection hole on the rotating pin shaft, and the positioning can be achieved by inserting a long bolt to connect, which is convenient and quick, and is easy to install and maintain. The seat plate with a bent portion has better ground adaptability.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The two ends of the rotating pin are used to connect with the machine. The rotating pin is locked with the leg and can move with two degrees of freedom. It is convenient for installation and maintenance. The long bolt and its matching nut and gasket, and the rotating pin provide two degrees of freedom in two directions respectively. The manufacturing cost is low and the installation is fast. When a fault occurs, it can be quickly checked and repaired.

[0018] 2. The support plate, plate ribs and seat plate can form a stable structure after installing the rotating pin, which can ensure the safety and reliability of the structure when subjected to forces in all directions.

[0019] 4. The structure can be adjusted according to the needs of the equipment (size, leg shape, etc.). In subsequent research and development, it can be transformed into a series of standard parts with varying sizes and specifications, further reducing production costs and improving adaptability. It has the advantages of strong adaptability and high degree of marking in the application of machinery of different specifications.

[0020] In summary, the support legs for uneven ground support described in the present invention have strong adaptability and guaranteed structural strength, can cope well with uneven non-paved road surfaces, complex structures, etc., and can achieve a good balance between environmental adaptability, structural strength, cost and manufacturing and installation difficulty.
