Description

Concrete compressive strength detects resilient mounting Technical Field The utility model relates to the technical field of concrete compressive strength detection, in particular to a concrete compressive strength detection rebound device. Background The concrete strength rebound detector consists of a shell, a pointer, a spring, a heavy hammer, a rebound rod and other parts, wherein the working principle is based on the interaction of elastic collision and inelastic collision, the maximum rebound distance of the heavy hammer is displayed in the name of a rebound value (the ratio of the maximum rebound distance to the initial length of the spring), the rebound value has a certain correlation with the concrete compressive strength, and the estimated value of the concrete compressive strength can be obtained through a table look-up or calculation formula. One end of the existing concrete strength rebound detector is of a conical structure, a spring rod is connected in a sliding mode, an operator holds the conical end face by one hand to keep the device vertical to the detection face, the operator is easy to be vertical to the detection end face and is not very accurate, the other hand is used for carrying out laborious jacking on the other end of the concrete strength rebound detector, the operation is troublesome and laborious, multiple points are needed to detect, and the labor load of the operator is increased. Disclosure of utility model 1. Technical problem to be solved The utility model aims to solve the technical problems that the vertical direction of the detection end face is easy and is not very accurate, the jacking is laborious, and the labor load of operators is increased. 2. Technical proposal In order to solve the technical problems, the technical scheme is that the rebound device for detecting the compressive strength of the concrete comprises a rebound detector and a rebound rod, wherein a connecting frame is sleeved outside the rebound detector, a sliding sleeve is arranged on the connecting frame in a sliding connection mode, a clamping piece capable of clamping the rebound detector is arranged in the sliding sleeve in a connecting mode, one end, far away from the rebound rod, of the connecting frame is connected with a labor-saving driving assembly, and the other end of the connecting frame is connected with a positioning assembly capable of temporarily positioning the rebound detector. Further, the link is including the solid fixed ring that is located both ends, relative connect between the solid fixed ring and be equipped with a plurality of guide bars, sliding sleeve circumference is connected relatively and is equipped with the guiding hole, guiding hole and guide bar sliding fit, the cooperation setting through solid fixed ring, sliding sleeve, guide bar and guiding hole is convenient for lead the slip of resilience detector for the resilience detector can stabilize the extrusion bullet and hit the pole, and then accomplishes the extrusion of bullet and hit the pole and draw in.
