[0031] Embodiment 2

[0032] As Figure 1As shown in the figure, the present invention discloses a working device for testing a lifting device, which includes a working platform 4. A torque detection system 1 and a load system 3 are arranged on the working platform 4. The torque detection system 1 and the load system 3 are respectively connected to both ends of the lifting device 2. The load system 3 is communicated with a hydraulic system 5. The torque detection system 1, the load system 3 and the hydraulic system 5 are respectively electrically connected to an electrical control system 6. The torque detection system 1 is used to detect the torque value of the lifting device 2 under a certain tensile load, and is used to compare with the theoretical torque value as the basis for judging whether the lifting device 2 is qualified. The load system 3 provides a load when testing the lifting device 2 and provides a load value through a load oil cylinder 307. The electrical control system 6 includes an electrical control cabinet, an operation console and cables, and is used for function setting and data display, displaying, storing and printing detection data, and forming a report for preservation and printing. A frequency converter is arranged in the electrical control system 6 to adjust the rotation speed of the motor reducer 101 so that the rotation speed of the motor reducer 101 meets the required numerical value of the rotation speed of the lifting device 2. After setting the required design rotation speed parameter value of this kind of lifting device on the screen of the operation console of the electrical control system, the PLC of the electrical control system drives the frequency converter, and then drives the rotation speed of the motor reducer 101 to meet the design rotation speed parameter value. The present invention controls the load system through the hydraulic system to apply pressure to the lifting device, controls the torque detection system to detect the torque value of the lifting device during rotation, and compares it with the standard torque value, so as to judge whether the lifting device is qualified for detection, and can detect the lifting device before assembly.

[0033] As Figures 2 to 5 shown, the working platform 4 includes a working platform welded part 401. An oil cylinder seat 402 and a motor mounting plate 403 are arranged on the working platform welded part 401. The torque detection system 1 includes a motor reducer 101. The motor reducer 101 is installed on the motor mounting plate 403. The motor reducer 101 is connected to the motor mounting plate 403 through a first bolt 102, a first washer 103 and a first nut 104. The load system 3 includes a load oil cylinder 303. The load oil cylinder 303 is installed on the motor mounting plate 403. The load oil cylinder 307 is connected to the oil cylinder seat 402 through a third pin shaft 308.

The torque sensor 109 is connected to the transmission shaft 117 through a second flat key 110.

[0035] The torque detection system 1 includes a bearing housing 114 which is installed on the working platform weldment 401. Two bearings 115 are installed on the bearing housing 114, and the two bearings 115 are sleeved on a transmission shaft 117. A bearing front cover 116 and a bearing rear cover 113 are respectively installed at the front and rear ends of the bearing housing 114, and the bearing front cover 116 and the bearing rear cover 113 are closely attached to the bearings 115. Specifically, the bearing front cover 116 is connected to the bearing housing 114 through a second bolt 107 and a second washer 108, the bearing rear cover 113 is connected to the bearing housing 114 through a third bolt 111 and a third nut 112, and the bearing housing 114 is connected through a fourth bolt 119 and a fourth washer 120.

[0036] The load system 3 includes a guide rail 301 which is installed on the working platform weldment 401. A slider 309 is slidably arranged on the guide rail 301, and the slider 309 can move freely on the guide rail 301. By adopting the free movement of the slider 309 on the guide rail 301, when the hoisting device 2 is being detected, it can move flexibly, reduce the moving resistance, and improve the loading accuracy of the load cylinder 307. A slide rail weldment 303 is connected to the slider 309. One end of the slide rail weldment 303 is connected to the hoisting device 2, and the other end is connected to the load cylinder 307. The slide rail weldment 303 is connected to the load cylinder 307 through a second through pin 306 and is connected to the hoisting device 2 through a fourth pin 310. The slider 309 is connected to the slide rail weldment 303 through a fifth bolt 304 and a fifth washer 305. When processing the working platform 4, the distances from the pin holes of the oil cylinder seat 402 and the two ends of the slide rail weldment 303 to the working platform weldment 401 are kept consistent, ensuring that after the load cylinder 307 and the hoisting device 2 are installed, they are kept in the horizontal direction, preventing the generation of torque, ensuring the accuracy of the load value of the load cylinder 307, and further ensuring the accuracy of the torque value detected by the hoisting device 2, thereby ensuring the accuracy of the detection by the hoisting device.

[0037] As Figure 6 shown, the hydraulic system 5 includes a hydraulic pump station 501. The hydraulic pump station 501 is communicated with the load cylinder 307 through a first hydraulic hose 502 and a second hydraulic hose 503. When the hoisting device 2 is being detected, the hydraulic system 5 provides hydraulic power to the load cylinder 307 of the load system 3, driving the load cylinder 307 to contract and providing a load. A pressure regulating valve is arranged on the hydraulic pump station 501 for regulating the system pressure, and thus regulating the load parameter values. At the same time, a pressure gauge is arranged on the control panel for displaying the load pressure value. The hoisting device 2 is subjected to a tensile force to detect whether the assembly of the components of the hoisting device 2 meets the design requirements.

[0038] Through the hoisting device detection apparatus of the present invention, it is possible to solve the problem of whether the assembly quality of the hoisting device meets the design requirements after assembly, without the need to place it on the whole machine for detection, saving a large amount of man-hours and costs. At the same time, the torque detection and tensile load detection systems of this detection device are set and detected according to the design parameters of the hoisting device, solving the problem that the torque values are basically the same on the same site during actual punching detection. The detection data is true and reliable, the model range of the hoisting device detected is wider, it is not restricted by the site, and the detection efficiency is high.

[0039] Embodiment 3

[0040] On the basis of the embodiment, this embodiment discloses a detection method for a working device for hoisting device detection, including the following steps:

[0041] Step 1, before detection, connect the front end of the assembled hoisting device 2 to the transmission shaft 117 through the first pin shaft 118, connect the rear end of the hoisting device 2 to the slide rail welded part 303 through the fourth pin shaft 310, and start the motor reducer 101, the load cylinder 303, the hydraulic pump station 501, and the electrical control system 6.

[0042] Step 2, the electrical control system 6 receives the load parameters of the hoisting device 2 detected by the load cylinder 303, and controls and adjusts the pressure regulating valve on the hydraulic pump station 501 according to the load parameters, so that the load parameters of the load cylinder 303 meet the load parameters of the hoisting device 2.

[0043] Step 3, the electrical control system 6 controls the frequency converter therein to adjust the speed of the motor reducer 101 so that the speed of the motor reducer 101 meets the design speed requirements of the hoisting device 2.

[0044] Step 4, under the loading of the load cylinder 307, when the load parameters meet the design requirement values of the hoisting device 2 and the rotation of the motor reducer 101 meets the design requirement values of the hoisting device 2, the torque sensor 109 measures the actual torque value of the hoisting device 2, and displays it through the console screen, and compares the actual torque value with the standard torque value of the hoisting device 2 to determine whether it is within its error range. If it is within the error range, it is determined that the detection is qualified, otherwise it is determined that the retrieval is unqualified, and finally the detection data is output.

[0045] The present invention controls the load system to apply pressure to the hoisting device through the hydraulic system, controls the torque detection system to detect the torque value of the hoisting device during rotation, and compares it with the standard torque value, so as to determine whether the hoisting device is qualified for detection. It can detect the hoisting device before assembly, avoiding the problem of difficult disassembly caused by unqualified detection after the hoisting device is installed, and the risk problem caused by the failure of the hoisting device without detection.

[0046] The above are only the preferred embodiments of the present invention.
