Abstract
The utility model discloses a roadway junction bracket for mining. The roadway junction bracket for mining comprises an arc-shaped bottom beam, a brace, a cable clamp, a three-core arch crown beam and a top beam support plate, wherein the brace is connected with the arc-shaped bottom beam through a welding connection plate by using a screw, the brace is connected with the three-core arch crown beam through the cable clamp, brackets of the support plate are respectively and fixedly arranged on the upper portion of the three-heart arch crown beam at intervals symmetrically, and a horizontal top beam support plate is fixedly connected to the upper end of the brackets of the support plate. The roadway junction bracket for mining is suitable for being used for supporting a T-crossing road, a cross road of roadway and the like, and is reasonable in structure, safe and reliable and the like.
Description
Technical field
The utility model belongs to support technology field, underworkings crosspoint, mine.
Background technology
Because mine underworkings pressure from surrounding rock is bigger, adopt mining worker's steel support pattern or adopt U steel+whitewashing combined supporting for the permanent openings is general, improved supporting intensity so greatly.But in the intersection, tunnel and the crosspoint supporting be always the construction difficult point.The support of construction supporting mainly is made up of back timber, pillar, bottom girder herein at present; Back timber and pillar, pillar and bottom girder all are to link together through screw through welding connecting plate separately, and this support and worker's steel ladder shape support basically identical on principle often cause the back timber compressive deformation in actual the use; The deformation of the surrounding rock in tunnel unstability; The influence safety in production often needs place under repair, time-consuming, effort.
The utility model content
The purpose of the utility model provides a kind of mining tunnel rational in infrastructure, safe and reliable, non-damageable crosspoint support.
To achieve these goals; The utility model comprises: arc bottom girder, pillar, card cable, basket handle arch back timber, back timber supporting plate; Pillar and arc bottom girder utilize screw to link together through the welding connecting plate; Pillar and basket handle arch back timber link together through the card cable, and symmetrical respectively fixed interval is provided with pallet stand on basket handle arch back timber top, are fixedly connected with the horizontal top bar supporting plate in the pallet stand upper end.
Like this when carrying out supporting; Pillar and arc bottom girder utilize screw to link together through the welding connecting plate, and back timber connected with being connected through the card cable of post, and the pressure of back timber supporting plate is passed to the basket handle arch back timber through pallet stand; Because the back timber of support is the basket handle arch back timber; Its stressed even supporting intensity increases greatly, and has increased the tunnel useful area on the original basis and be beneficial to ventilation, can effectively control roadway junction surrouding rock deformation and destroy.Be applicable to the supporting that tunnel T-shaped mouth, intersection etc. are located, have characteristics such as rational in infrastructure, safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Can know that by Fig. 1 the utility model comprises: arc bottom girder 1, pillar 2, card cable 3, basket handle arch back timber 4, back timber supporting plate 5.Arc bottom girder and basket handle arch back timber adopt U-shaped steel processing and fabricating; Pillar adopts the i iron processing and fabricating; The pillar 2 on both sides utilizes screw to link together with arc bottom girder 1 through the welding connecting plate; The pillar 2 on both sides links together with the card cable 3 of basket handle arch back timber 4 through both sides, and symmetrical respectively fixed interval is provided with pallet stand 5 on basket handle arch back timber 4 tops, and the upper end of each pallet stand should be positioned on the same plane; Be fixedly connected with horizontal top bar supporting plate 6 in pallet stand 5 upper ends, the back timber supporting plate adopts the steel plate processing and fabricating.
