Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, an anti-deflection damping support wheel assembly for a single oil cylinder of a shield tunneling machine comprises a support rod 1, a sleeve 2 and an elastic element 3, wherein the sleeve 2 and the elastic element 3 are coaxially sleeved on the support rod 1 in a sliding manner and used for being connected with a shoe supporting plate of the single oil cylinder, a first retaining ring 4 is fixedly arranged at the top end of the sleeve 2, a retaining ring 5 is fixedly arranged on the support rod 1, the elastic element 3 is connected between the first retaining ring 4 and the retaining ring 5, and the bottom end of the support rod 1 is in butt joint with a shield body of the shield tunneling machine. In this embodiment, the elastic element 3 is a coil spring disposed in an annular gap between the support rod 1 and the sleeve 2.
In practical application, two sides of each single-oil-cylinder shoe supporting plate are respectively provided with an anti-deflection damping supporting wheel assembly, the supporting wheel assemblies are welded and fixed with the shoe supporting plates through sleeves 2, the abutting ends of the supporting rods 1 are in contact with the shield body of the shield machine to provide supporting force, and the shoe supporting plates compress the elastic elements 3 to enable the sleeves 2 to slide along the supporting rods 1 until the elastic elements 3 provide enough supporting force. When the oil cylinder contracts, the supporting wheel component supports the shoe supporting plate to move along with the oil cylinder, if the shoe supporting plate is twisted, the elastic element 3 which is compressed in the moving process can be automatically adjusted to be normal, and when impact is generated, the supporting wheel component can be used for damping.
It will be appreciated that in practical design, the abutting end of the support rod 1 is connected to the abutting wheel 7 through the wheel fork 6, the abutting wheel 7 is rotatably connected to the wheel fork 6 through the rotating shaft 8, and the abutting wheel 7 is in contact with the shield body of the shield machine to provide the supporting force.
Referring to fig. 1 and 3, in some embodiments, an oil injection hole 201 is formed in the wall of the sleeve 2, and grease can be added into the sleeve 2 through the oil injection hole 201, so that the sleeve 2 can move smoothly. In the present embodiment, the oil filler hole 201 is opened in the middle upper portion of the sleeve 2. The length of the support rod 1 is suitably controlled to be 300mm-360mm, and if the length is too long, bending may occur in practical application.
Referring to fig. 1 and 2, in some embodiments, a second retaining ring 9 is slidably disposed on the support rod 1 below the retaining ring 5, the second retaining ring 9 is fixedly connected to the bottom end of the sleeve 2, and has an inner diameter smaller than the outer diameter of the retaining ring 5, and two ends of the elastic element 3 respectively abut against the first retaining ring 4 and the retaining ring 5. The second retainer 9 is slidably disposed on the support rod 1 below the retainer 5 to prevent the sleeve 2 from sliding out of the top end of the support rod 1 along with the shoe plate.
In engineering practice, after the anti-deflection damping support wheel assemblies of the embodiment are arranged on two sides of the single-oil-cylinder shoe supporting plate of the shield machine, the shoe supporting plate hardly deflects under the supporting action of the support wheel assemblies, even if the shoe supporting plate deflects, the shoe supporting plate deflects slightly, the slight deflection can be automatically corrected in the process of pushing the oil cylinder, and the problems of dislocation and water leakage caused by abrasion of the shoe supporting plate corner, deflection of the shoe supporting plate relative to the oil cylinder, falling of a water stop strip and falling of the water stop strip do not occur.
The above examples are merely illustrative of the present invention clearly and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Nor is it intended to be exhaustive of all embodiments.
