Abstract
The invention discloses a light cast steel tray and solves the problem that a coal mine support is poor in tensile strength effect. The light cast steel tray is characterized by comprising a hexagonal nut 1, a trapezoidal steel tray 2 and an anchor rod 3, the middle of the steel tray 2 is provided with a central hole 4, two semicircular grooves 5 are symmetrically arranged at two ends of the central hole 4, one end of the anchor rod 3 is fixed on a coal layer top plate by anchoring agent, the other end of the anchor rod penetrates through a steel band and the central hole 4 in the middle of the steel tray 2 and is fixed by a nut. The light cast steel tray has the advantages of high tensile strength, large binding surface, small occupation space, low labor intensity and support cost and good support effect and is applicable to support of a coal mine shaftway.
Description
Technical field:
The invention belongs to the technical field that coal mine machinery equipment is made, be specifically related to a kind of cast steel light tray, be adapted to colliery tunnel support.
Background technology:
Known to the inventor, present pallet a multitude of names of using of coal mine support has plenty of that the intensity pulling force is inadequate, bonding surface is little, does not have the effect of safety support; Although the pulling force that has is enough strong, volume is excessive, takes up room, and labor strength increases, and causes the down-hole support cost to strengthen.Impact is normal produces.
Summary of the invention:
Purpose of the present invention is exactly for overcoming above deficiency, provides a kind of and protects effectively, and cost is low, and labour intensity is little, the cast steel light tray that the intensity pulling force is large.
Technical scheme of the present invention is to realize like this, described a kind of cast steel light tray, by hex nut 1, steel body pallet 2, anchor pole 3 forms, it is characterized in that arranging a trapezoidal steel body pallet 2, middle part at steel body pallet 2 is provided with centre bore 4, is symmetrical arranged two semi-circular recesses 5 at the two ends of centre bore 4, and one of anchor pole 3 is fixed in roof with Anchor Agent, the centre bore 4 of the middle part setting of steel band, steel body pallet 2 is passed in the other end, fixes with nut.
Cast steel light tray of the present invention, compare with other pallets: have that the intensity pulling force is large, bonding surface is large, it is little to take up room, and labor strength is little, and support cost is low.The advantage that supporting effect is good
Description of drawings:
Accompanying drawing is cast steel light tray structure chart
Among the figure: 1. hex nut, 2. steel body pallet, 3. anchor pole, 4. centre bore is 5. semicircle recessed.
The specific embodiment:
The present invention is described in further detail below in conjunction with accompanying drawing embodiment, cast steel light tray as shown in drawings, its structure setting is by hex nut 1, pallet 2, anchor pole 3 forms, a trapezoidal steel body pallet 2 is set, is provided with centre bore 4 at the middle part of steel body pallet 2, be symmetrical arranged two semi-circular recesses 5 at the two ends of centre bore 4.Using method is that of anchor pole 3 is fixed in roof with Anchor Agent, and the centre bore 4 of steel band, steel body pallet 2 is passed in the other end, and is fixing with hex nut 1.
