Abstract
The utility model discloses a displacement detection device comprising a displacement detector. A top plate and a back plate of a bracket are welded together so as to form a reversed L shape, an upper-layer plate is welded above a left side plate and a right side plate of the bracket, the displacement detector is fixedly connected below the bracket by using a bolt, screw holes are arranged on the top plate and the upper-layer plate, screws on bolts are arranged in the screw holes, the screws and the screw holes are in clearance fit, the top plate and the upper-layer plate are clamped between the heads of the bolts and nuts connected to the screws in a rotary way, spiral springs are sleeved on the screws, the spiral springs are arranged between the top plate and the upper-layer plate, the diameters of the spiral springs are greater than the diameters of the screw holes, and at least two bolts are matched with the nuts for connecting the top plate and the upper-layer plate together. Because detection wheels always contact with a rail under the action of pressure of the springs, the phenomenon of slippage or derailment of the detection wheels can be effectively prevented, so that the accuracy of positioning of driving displacement can be effectively enhanced.
Description
Technical field
The utility model relates to detecting device, particularly a kind of displacement detector.
Background technology
At present, the displacement detecting form on the hoisting crane mainly contains two kinds.First kind of test format is to utilize the own wt of displacement detector that detection wheel 9 is contacted with track; Displacement detector and driving hinge are together; On the detection wheel 9 fixed test wheel shafts, the turning cylinder that detects on wheel shaft and the coder 10 is fixed together, and calculates through the number of turns of 10 pairs of detection wheels of coder, 9 walkings; Realize the accurate location in the driving walking process, supplementary electrical device is realized the automation control of driving; Because driving the situation that detection wheel 9 de-orbits occurs sometimes in operational process, thereby the accuracy of the displacement location that causes driving a vehicle reduces.Second kind of test format is to utilize the detected driving wheel walking number of turns; Count through coder; Realize the displacement location of driving; Because the driving wheel skidding occurs sometimes in the middle of operation, the detected wheel walking number of turns is inaccurate, thereby the accuracy of the displacement location that also can cause driving a vehicle reduces.
The utility model content
The purpose of the utility model provides a kind of displacement detecting that can effectively prevent and takes turns derailing or driving tyre skidding phenomenon, makes driving displacement location displacement detector more accurately.The technical scheme of the utility model is such completion, and a kind of displacement detector comprises displacement detector; It is characterized in that: the top board of bearing becomes L shaped with the backboard weld together, is welded with top plate above the left side plate of support, is connected with displacement detector with bolt below the support; Top board and top plate are provided with screw hole; Being provided with the screw rod on the bolt in the screw hole, is free-running fit between screw rod and the screw hole, and top board and top plate are clipped in bolt head and are screwed between the nut on the screw rod; Be with coil spring on the screw rod; Coil spring is located between top board and the top plate, and helical spring diameter has at least two bolts and nut to match top board and top plate are linked together greater than the diameter of screw hole.Having four bolts and nut to match links together top board and top plate.Being located in the spacing hole on the top plate with the locating plate of top board weld together, is free-running fit between described spacing hole and the locating plate.Described locating plate is located in the spacing hole on the lower plywood that is welded on the left side plate, is free-running fit between described spacing hole and the locating plate.Said backboard is provided with mounting hole.Top board and backboard both sides are welded with brace panel.Header board is with two brace panels and top board weld together.
The technique effect of the utility model is: because detection wheel under the pressure effect of spring, contacts with track all the time, can prevent effectively that it from skidding or derailment occurring, thereby can effectively improve the accuracy of driving displacement location.
