Abstract
The utility model provides a wing compressible pallet and a horseshoe cushion, and relates to the field of mine roadway supporting equipment. The wing compressible pallet comprises a pallet body and a pallet hole formed in the center of the pallet body; the cross section of the pallet body adopts an arc-shaped structure; two ends of the arc-shaped structure extend symmetrically and smoothly outward to form small arc-shaped structures; the outer edge of each small arc-shaped structure extends smoothly to be horizontal; the horseshoe cushion matched with the wing compressible pallet comprises a cushion body; a mesopore is formed in the center of the cushion body; and one end of the cushion body adopts a plane surface, and the other end thereof adopts an arc-shaped structure corresponding to the arc-shaped structure at the top of the wing compressible pallet. The shape of the wing compressible pallet shows that the wing compressible pallet is provided with better elasticity, large compressible distance, and high bearing capacity, thereby realizing matching with anchor rods and anchor cables of various types; and the wing compressible pallet is also provided with good adaptability, particularly better supporting effect to a roadway with high stress and larger deflection.
Description
Technical field
The utility model relates to mine timbering equipment field, and particularly a kind of wing allowing pressed pallet and pressed the supporting water chestnut pad of pallet with wing allowing.
Background technology
The supporting of existing mine working mainly is to adopt high strength anchor bar to join to allow the pressure pallet realize.Because existing allowing presses pallet yield deformation distance little, supporting capacity is low, and after a large amount of support anchor rods were installed, what be subjected to that back or two helps pressed and broken, and loses support action, causes the tunnel gross distortion.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned shortcoming, provides a kind of yield deformation distance big, and the wing pressure pallet that allows that supporting capacity is high also provides simultaneously and wing allowing pressed the supporting water chestnut pad of pallet.
For achieving the above object, the technical solution of the utility model is the wing pressure pallet that allows, comprise disk body and the dish hole that is arranged at the disk body center, top, disk body cross section is an arc, and arc two ends symmetry outwards smoothly extends to form little arc, and little arc outside smoothly extends into level.
Press the supporting water chestnut pad of pallet with above-mentioned wing allowing, comprise pad, the pad center is provided with mesopore, and pad one end is the plane, the other end for the wing arc of pressing the indent that the tray top arc adapts that allows.
Wing allowing when pressing pallet to use installs anchor pole earlier, presses pallet to be inserted in the anchor pole wing allowing again, then the water chestnut cushion cover is gone in the anchor pole, and nut is first-class, adjust tray arrangement, with the pretightning force spanner anchor pole is tightened, guarantee that bolt pretension reaches setting and gets final product.
Wing allowing presses the shape of pallet to determine it to have elasticity preferably, allows and presses distance big, and the bearing capacity height can be realized the coupling with all kinds anchor pole and anchor cable; Conformability is good, particularly to the heavily stressed and big roadway support better effects if of deflection.
Water chestnut pad and wing allowing press pallet to be used, and make wing allowing press pallet to reach best result of use.

Fig. 3 uses aerofoil profile and allows the supporting assembling drawing of pressing pallet
Among the figure: 1, disk body 2, dish hole 3, pad 4, mesopore 5, anchor pole 6, allow and press pallet 7, water chestnut pad 8, nut
The specific embodiment
Embodiment 1 as shown in Figure 1, the wing pressure pallet that allows comprises disk body 1 and is arranged at the dish hole 2 at disk body center that its top, cross section is an arc, arc two ends symmetry outwards smoothly extends to form little arc, little arc outside smoothly extends into level.
Claims (2)
1, the wing pressure pallet that allows comprises disk body and the dish hole that is arranged at the disk body center, it is characterized in that top, disk body cross section is an arc, and arc two ends symmetry outwards smoothly extends to form little arc, and little arc outside smoothly extends into level.
2, the water chestnut pad comprises pad, and the pad center is provided with mesopore, and pad one end is the plane, it is characterized in that the pad other end for the wing arc of pressing the indent that the tray top arc adapts that allows.
