Abstract
The utility model discloses a cast steel bell-shaped pallet consisting of a cast steel bell-shaped pallet body (1), an anchor rod (2) and a nut (3), and is characterized in that the cast steel bell-shaped pallet takes the shape of a bell, and has an anchor rod hole (6) in the center; an inferior oblique surface (4) is arranged at each end of the anchor rod hole (6) in a symmetric manner, and a concave arcuate slot (5) is provided between every two adjoining cast steel bell-shaped pallets.
Description
Technical field:
The utility model belongs to the technical field that mine mechanism is made, and is specifically related to the bell pallet of a kind of cast steel, is adapted to mine underworkings supporting.
Background technology:
Known to the inventor, roadway support under the coal mine at present, mostly adopt the supporting of reinforcing bar guiding principle band small size supporting plate, though use reinforcing bar guiding principle band in light weight, processing is simple, but stiffness is very little, and the effective support area is little, relatively poor to the mine roof supporting effect, also having to use has the steel band of model supporting to increase stiffness and flexing resistance, but the supporting area around its anchor pole is little, particularly when mine roof pressure is big, cause the supporting failure easily, cause the mine roof inbreak, when serious, the mine roof fall accident can occur and take place, be difficult to adapt to the big section of mine, the safety support of adopting the sky tunnel of large span.
Summary of the invention;
The purpose of this utility model is at above deficiency, and what provide a kind ofly is adapted to mine underworkings supporting, and anti-bending strength is good, and the supporting area is big, the bell pallet of the cast steel that security performance is good.
The utility model is to realize like this, its structure of the bell pallet of described cast steel is, form with anchor pole (2) and nut (3) by the casting bell tray body of cast steel (1), it is characterized in that the bell pallet of cast steel (1) is set to bell, the centre is provided with a bolthole (6), respectively be symmetrical arranged a lower inclined plane (4) at the two ends of bolthole (6), a concave arc groove (5) is set between the bell pallet of cast steel (1).Its operating principle is to need the mine roof place perforating of supporting, anchor pole (2) is penetrated the mine roof intraocular to be fixed, the bell tray body of cast steel (1) is provided with on the direction of lower inclined plane (5), go up the bolthole (6) that is provided with by the bell tray body of cast steel (1), to be pushed into mine roof on the bell tray body of cast steel (1) and be adjacent to along anchor pole (2), use the anchor pole (2) of nut (3) behind the bell tray body of cast steel (1) place of appearing that it is fastening again with it.
Adopt the advantage of the bell pallet of cast steel of the present utility model to be, the one, improved in the king-sized top board anchoring of mine roof pressure the flexural strength of supporting casted steel belt muscle side pallet; The 2nd, increased the supporting area; The 3rd, can prevent the support parts division, guaranteed the discharge space of support parts, improve the supporting capacity of mine roof supporting; The 4th, reduce labor intensity, saved raw material, reduced entreprise cost, increased economic benefit.
Description of drawings:
Accompanying drawing is the bell support holder structure figure of cast steel
Among the figure: 1. the bell tray body of cast steel, 2. anchor pole, 3. nut, 4. lower inclined plane, 5. lower inclined plane, 6. bolthole,
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing embodiment, the bell pallet of cast steel as shown in drawings, be to select the steel material that a kind of elasticity is strong, fatigue resistance is good to be made as the bell tray body of cast steel (1) by specification, be provided with bolthole (6) at the bell tray body of cast steel (1) middle part, respectively be symmetrical arranged a lower inclined plane (4) at the two ends of bolthole (6), a concave arc groove (5) is set in the middle of the bell tray body of cast steel (1).To be provided with on the direction of concave arc groove (5), and will be pushed into mine roof on the bell tray body of cast steel (1) along anchor pole (2), and be adjacent to it, with the anchor pole (2) of nut (3) behind casted steel belt muscle side pallet (1) appear locate it is fastening.The utility model adapts to general machining enterprise to be produced.
Claims (1)
1. its structure of the bell pallet of cast steel is, form with anchor pole (2) and nut (3) by the casting bell tray body of cast steel (1), it is characterized in that the bell pallet of cast steel (1) is set to bell, the centre is provided with a bolthole (6), respectively be symmetrical arranged a lower inclined plane (4) at the two ends of bolthole (6), a concave arc groove (5) is set between the bell pallet of cast steel (1).
