Abstract
The utility model relates to an anchor rod dynamometer, belonging to a dynamometer which is used for measuring and detecting the pulling force of the anchor rod in the anchoring and spraying laneways of a coal mine. The utility model is mainly composed of a housing 1, a piston 2, a pressure gauge 3, a supporting disk 6, etc. The utility model is characterized in that a conical stand structure is arranged between the working cylindrical surface of the piston 2 and a lower end surface; the center of the piston 2 is provided with a vertical circular hole A; the vertical circular hole A is used for the penetration of the anchor rod. The utility model which can accurately measure the value of the pulling force of the anchor rod has the advantages of simple structure and repeated use.
Description
The utility model belongs to and is used for measuring the dynamometer that bolting and shotcrete roadway detection anchor pole bears pulling force in the colliery.
Bolt-spray support has been widely used in the colliery tunnel support, understand the situation that anchor pole bears pulling force, be to judge bolting and shotcrete roadway quality quality, one of essential condition of roadway deformation situation, being used to detect the way that anchor pole bears pulling force at present is that the oil pressure pillow is fixed on anchor pole, and anchor is sprayed in the wall, external meter.In this measurement way, oil pressure is rested the head on fragile and can not be reused.
The purpose of this utility model is to design a kind of simple in structure, the easy to install and use and reusable novel anchor rod tension dynamometer of energy.
The utility model is mainly by housing 1, piston 2, and tensimeter 3, pallet 6 compositions such as grade is characterized in that the piston bottom is a circular cone structure, and even piston stress is distributed, and prevent unbalance loading; Have center pit on the piston, be used for penetrating of anchor pole; Butter is housed in the housing, is used to transmit pressure, and good seal performance.
The utility model has the advantages that simple in structurely, easy to install and use, can reuse.
Description of drawings: accompanying drawing is the utility model structural representation, 1-housing among the figure, 2-piston, 3-tensimeter, 4-butter, 5-anchor pole, 6-pallet, 7-nut, 8-O-ring seal, 9-joint.
The utility model is mainly by housing 1, piston 2, tensimeter 3, pallet 6, nut 7 compositions such as grade.At housing 1 center piston 2 is housed, there is a circular hole A at piston 2 centers, are used for penetrating of anchor pole 5, have seal groove on piston 2 and housing 1, and O-ring seal 8 is contained in the groove, and scribbles railway grease, can positiver sealing.Add earlier butter 4 during installation in box body 1, the piston 2 that O RunddichtringO 8 will be housed is again packed in the housing 1, loads onto joint 9 and tensimeter 3 then.When using in the down-hole, the utility model is enclosed within on the anchor pole 5, overlap top tray 6 again, tight top nut 7 is pressed on the piston 2 pallet 6, when the tunnel produces distortion, piston 2 pressurizeds, the butter 4 in the compressing housing 1 is passed to tensimeter 3 by joint 9 with pressure, just the axis force of anchor value can be obtained by tensimeter 3, thereby the deformation tendency in tunnel can be predicted.
Claims (3)
1, is used to measure the dynamometer that the bolting and shotcrete roadway anchor pole bears pulling force in a kind of colliery, mainly by housing 1, piston 2, tensimeter 3, pallet 6, nut 7, O-ring seal 8, joint 9 compositions such as grade, the bottom that it is characterized in that piston 2 is a circular cone structure, at piston 2 centers one vertical circular hole A is arranged, be used for penetrating of anchor pole 5.
2, dynamometer according to claim 1, the work face of cylinder that it is characterized in that piston 2 is to being circular cone structure between the lower surface, the lower surface area is less than the area of pallet 6.
