Technical Field
The invention relates to a limiting mechanism, in particular to a flexible steering limiting mechanism of a steering gear rotating shaft for engineering machinery.
Background
At present, a limiting mechanism is additionally arranged on a rotating shaft of a steering gear for the existing engineering machinery to prevent the rotating shaft from being locked or prevent the rotating torque from being too large to cause the damage of equipment, the limiting mechanism for the steering gear for the engineering machinery adopts rigid limiting, and although the service life can be prolonged, the steering gear has obvious vibration sense in the operation process, is inconvenient to operate and has poor hand feeling.
Disclosure of Invention
The invention aims to solve the defects and provide the flexible steering limiting mechanism of the steering gear rotating shaft for the engineering machinery, which adopts a flexible connection mode, has better limiting effect and is convenient to operate.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the utility model provides a flexible stop gear that turns to of direction machine axis of rotation for engineering machine tool, includes direction machine axis of rotation and the tube-shape casing of cover form in the direction machine axis of rotation, its characterized in that: still including moving about pressure disk, connecting rod, two sections telescopic links, compression spring and spacing jump ring, the direction machine axis of rotation is established to the pressure disk cover that moves about, and its terminal surface is connected with the connecting rod contact down, the middle part of establishing the connecting rod is worn to the direction machine axis of rotation the both ends of connecting rod are all connect and are established two sections telescopic links the compression spring is established to the cover on the two sections telescopic links, the lower extreme at the connecting rod is established to spacing jump ring.
As a preferred technical scheme, the double-section telescopic rod is formed by combining single rods with umbrella-shaped caps at the end parts, and two connected rod bodies are tightly spliced.
As an optimal technical scheme, bases are arranged at two ends of the double-section telescopic rod, and arc-shaped bayonets are formed in the side ends of the bases.
Preferably, the deformation amount of the compression spring is greater than or equal to the maximum stroke amount of the connecting rod sliding downwards along the rotating shaft of the steering gear.
As a preferred technical scheme, two ends of the connecting rod are respectively connected with the upper single rod of the double-section telescopic rod.
The invention has the beneficial effects that: the structure is reasonable, the flexible limiting connection mode is adopted, the vibration reduction effect is good, the installation and the use are convenient, and the limiting effect is less.
Drawings
FIG. 1 is a schematic structural diagram of a steering gear rotating shaft flexible steering limiting mechanism for engineering machinery according to the present invention;
FIG. 2 is an exploded view of the dual telescoping pole of FIG. 1;
in the figure: the device comprises a steering gear 1, a steering gear rotating shaft 2, a cylindrical shell 3, a traveling platen 4, a connecting rod 5, a double-section telescopic rod 5, a single rod 5-1, a base 5-2, a compression spring 6 and a limiting clamp spring 7.
Detailed Description
So that the manner in which the above recited features of the present invention can be understood and readily understood, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings, wherein:
as shown in fig. 1-2, a flexible stop gear that turns to of direction machine axis of rotation for engineering machine tool, including direction machine axis of rotation 1 and the tube-shape casing 2 of cover form in direction machine axis of rotation 1, still including moving about pressure disk 3, connecting rod 4, two sections telescopic links 5, compression spring 6 and spacing jump ring 7, direction machine axis of rotation 1 is established to 3 covers of pressure disk that move about, its lower terminal surface is connected with the contact of connecting rod 4, direction machine axis of rotation 1 wears to establish the middle part of connecting rod 4, all connect at the both ends of connecting rod 4 and establish two sections telescopic links 5, compression spring 6 is established to the cover on two sections telescopic links 5, the lower extreme at connecting rod 4 is established to spacing jump ring 7.
In this embodiment, the two-section telescopic rod 5 is composed of single rods 5-1 with umbrella-shaped caps at the ends, and two connected rod bodies are closely inserted.
In this embodiment, two ends of the double-section telescopic rod 5 are both provided with bases 5-2, and the side ends of the bases 5-2 are provided with arc-shaped bayonets.
In the present embodiment, the amount of deformation of the compression spring 6 is greater than or equal to the maximum stroke amount of the link sliding downward along the steering shaft 1.
In this embodiment, the two ends of the connecting rod 4 are respectively connected with the upper single rod 5-1 of the double-section telescopic rod 5.
The specific working principle of this embodiment is as follows: when the steering gear rotating shaft 1 rotates, the connecting rod 4 is driven to slide downwards, the moving pressure plate 3 also presses down the connecting rod, the single rod 5-1 connected with the two ends of the connecting rod 4 moves downwards, the compression spring 6 generates deformation, when the connecting rod 4 slides downwards to be in contact with the limiting clamp spring 7, the downward sliding of the connecting rod 4 is limited, the maximum stroke amount is reached, when the steering gear rotating shaft 1 rotates, the compression spring 6 and the limiting clamp spring 7 rebound, the steering gear rotating shaft 1 rotates more labor-saving, and the operation is more convenient.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
