Description

Technical Field

[0001] The utility model relates to the technical field of crane inspection and detection, in particular to a crane inspection and detection device. Background Technique

[0002] The working characteristic of lifting equipment is intermittent movement, that is, in a working cycle, the corresponding mechanisms of actions such as material taking, transporting, and unloading work alternately. Cranes are more and more widely developed and used in the market. The wire rope varieties used in supporting cranes include phosphating coated wire ropes, galvanized wire ropes, and smooth wire ropes.

[0003] At present, most of the commonly used crane inspection and detection devices in this field are in an independent form. When in use, the detection device is installed on the crane, and then the wire rope is detected and flaw detected through the detection device. At the same time, most detection devices also have the function of angle adjustment, and the angle of the flaw detector can be adjusted according to the change of the wire rope to better detect the wire rope. However, the angle of the flaw detector of this type of crane inspection and detection device is adjusted manually during adjustment, and it is impossible to automatically adjust the angle of the flaw detector according to the vertical change of the wire rope during the operation of the wire rope.

[0004] For example, the Chinese authorized utility model patent with the publication number of CN220930756U is a crane inspection and detection device in the prior art. The wire rope flaw detector in the prior art needs the user to adjust the angle through a hydraulic press.

[0005] Therefore, we propose a crane inspection and detection device. Content of the Utility Model

[0006] One technical problem to be solved by this application is that the prior art cannot automatically adjust the angle of the flaw detector according to the vertical change of the wire rope.

[0007] To solve the above technical problem, the embodiment of this application provides a crane inspection and detection device, including a protection box. A second mounting plate is arranged on the inner top of the protection box. A wire rope flaw detector is installed on the top of the second mounting plate. One end of the bottom of the second mounting plate is hinged with a support block. A pressure sensor is installed at the other end of the bottom of the second mounting plate. An electric telescopic rod is installed inside the protection box. The output end of the electric telescopic rod is connected to the pressure sensor. The support block is installed on the inner bottom of the protection box;

[0008] Wherein the pressure sensor is electrically connected to the electric telescopic rod through a controller arranged inside the protection box.

[0009] In some embodiments, hinge brackets are arranged at both ends of the bottom of the second mounting plate. One of the second mounting plates is hinged to the support block, the top of the other hinge bracket is connected to the pressure sensor, and the bottom is hinged to the output end of the electric telescopic rod.

[0010] In some embodiments, it further includes a bottom plate and a column. The column is installed on the top of the bottom plate, a support plate is provided at the top of the column, and the protection box is installed on the top of the support plate.

[0011] In some embodiments, a hydraulic cylinder is arranged inside the column, and the output end of the hydraulic cylinder is connected to the bottom of the support plate.

[0012] In some embodiments, a first sliding groove is installed inside the protection box. A slider is slidably installed inside the first sliding groove. A first mounting plate is fixedly installed on the top of the slider. The support block and the electric telescopic rod are both installed on the first mounting plate. The first mounting plate is fixed to the slider by screws. One end of the first sliding groove penetrates through the protection box;

[0013] One end of the protection box is hingedly installed with a box door.

[0014] In some embodiments, a second sliding groove is formed on one side of the protection box. A connecting rod is slidably connected inside the second sliding groove. A connecting block is provided at one end of the slider, and one end of the connecting rod is fixedly connected to the connecting block.

[0015] In some embodiments, a lead screw is rotatably installed on one side inside the protection box. A nut seat is fitted on the lead screw. The other end of the connecting rod is connected to the nut seat. The second sliding groove communicates with the inside of the protection box;

[0016] A driving motor is installed inside the protection box, and the output end of the driving motor is fixedly connected to one end of the lead screw.

[0017] The utility model at least has the following beneficial effects: The crane inspection and detection device can achieve the effect of automatically adjusting the angle of the wire rope flaw detector through the arranged pressure sensor, controller and electric telescopic rod. When the verticality of the wire rope changes, the wire rope presses down one end of the wire rope detector or moves upward to reduce the pressure on one end of the wire rope flaw detector. At this time, after the pressure sensor detects the pressure change, the controller starts the electric telescopic rod, and the electric telescopic rod drives one end of the wire rope flaw detector to move up and down, thereby achieving the purpose of automatically adjusting the angle.
