Description

Technical Field

[0001] The utility model belongs to the field of steel bar detectors, and in particular relates to a steel bar detector used for civil engineering quality supervision. Background Art

[0002] Rebar is an indispensable building material in construction projects. On construction sites, where concrete needs to be poured, steel bars are often used to build a shape that needs to be poured first. This is to ensure that the building has sufficient strength after pouring and avoid danger. Due to the large-scale use of steel bars in construction, there are strict requirements on the strength of steel bars, and a steel bar detector is needed to test the strength of the steel bars.

[0003] The steel bar monitoring device in the existing technology has a relatively simple clamping structure for steel bars, and the clamping is not firm enough. When the steel bars are stretched, their two ends will move or detach from the clamping structure, affecting the detection effect of the steel bars; the sizes of the steel bars are different, and the clamping blocks that clamp the steel bars cannot be replaced to better fit the curved surface of the steel bars. The inability to fit the curved surface of the steel bars will cause the contact area to become smaller and affect the friction force, further resulting in a loose clamping of the steel bars.

[0004] A Chinese patent with publication number CN214749430U discloses a steel bar detector for civil engineering quality supervision; it includes a first clamp and a second clamp for clamping steel bars, the first clamp matches the second clamp, and also includes: a support frame for installing the first clamp and the second clamp; wherein the first clamp is fixedly connected to the bottom end of the support frame; a rotating plate is rotatably connected to the upper end of the support frame; a guide rod is symmetrically fixedly connected to the rotating plate, and the second clamp is slidably connected to the guide rod; in the utility model, the support frame, the first clamp and the second clamp facilitate the clamping of steel bar samples, the driving motor, the driving gear and the driven gear facilitate the movement of the threaded rod, and the guide rod ensures the stability of the position between the first clamp and the second clamp.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a steel bar detector for civil engineering quality supervision, thereby solving the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A steel bar detector for civil engineering quality supervision comprises: a base, a vertical plate fixedly connected to the top surface of the base in an axisymmetric manner, a hydraulic rod fixedly connected to the side surface of the vertical plate in an axisymmetric manner, and a clamping assembly fixedly connected to one end of the hydraulic rod;

[0009] The clamping assembly includes a slot plate fixedly connected to one end of the hydraulic rod, the back of the slot plate is fixedly connected to a driving structure, both ends of the driving structure are axially symmetrically connected to connecting rods, the top of the connecting rod is fixedly connected to a clamping block, and the clamping block is slidably connected to the surface of the slot plate.

[0010] Optionally, the driving structure includes a driving motor arranged on the side of the slot plate, the output end of the driving motor is fixedly connected to a rocker arm, both ends of the rocker arm are rotatably connected to a pull rod, and one end of the pull rod is rotatably connected to a connecting rod.

[0011] Optionally, a brake structure is provided on the back of the drive motor, and the side surface of the drive motor is fixedly connected to the surface of the slot plate.

[0012] Optionally, a mounting screw hole is provided on the surface of the clamping block, a socket is provided on the side of the clamping block, and a contact assembly is provided inside the socket.

[0013] Optionally, the contact assembly includes an insertion rod inserted into the inside of the socket, one end of the insertion rod is fixedly connected to an arc block, and a through hole that fits with the mounting screw hole is opened on the surface of the insertion rod.

[0014] Optionally, a mounting rod is sleeved inside the mounting screw hole, and a thread for locking is provided at the bottom end of the mounting rod.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0016] 1. Through the setting of the clamping assembly, the driving motor drives the pendulum rod fixed at its output end to rotate. The pull rods connected by the rotation at both ends of the pendulum rod will pull the connecting rod to move, so that the connecting rod drives the clamping block to move on the top surface of the groove plate, placing the steel bar on the side of the contact assembly, and then the clamping block squeezes and fixes the steel bar through the contact assembly. At the same time, the brake structure of the driving motor can effectively prevent the reversal of the driving motor from causing the clamping to loosen, thereby achieving a more secure clamping of the steel bar and preventing it from loosening.

[0017] 2. Through the setting of the contact assembly and the mounting rod, according to the diameter of the steel bar, select the arc block of appropriate size, insert the plug rod fixed on the back of the arc block into the socket on the side of the clamping block, and then screw the mounting rod into the mounting screw hole and through hole on the surface of the plug rod to complete the limit fixation of the plug rod, so that the arc block used for clamping can be installed and fixed, thereby facilitating the replacement of the arc block that fits the gear of the steel bar diameter, increasing the contact area and friction with the surface of the steel bar, and further improving the clamping firmness of the steel bar.
