Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a cable testing device for lifting height. Background Technology

[0002] In existing technologies, grain depot transport vehicles often use hydraulic unloading platforms to lift and unload the grain. When the hydraulic system operates on the hydraulic unloading platform, it is necessary to detect the lifting height in order to control the change in lifting angle and avoid unloading errors caused by height.

[0003] Therefore, it is essential to provide a lifting height cable detection device to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a lifting height cable detection device. When the A-beam is lifted by the lifting cylinder, the cable mechanism installed on both sides of the lifting cylinder can detect the displacement of the heavy-duty cable through the cable sensor. The cable sensor converts the displacement distance detection into an electrical signal for transmission. The cable roller and grooved rotating roller installed at the upper and lower ends of the lifting cylinder can assist the heavy-duty cable to ensure the accuracy of the heavy-duty cable movement, thereby improving the accuracy and convenience of detection.

[0005] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0006] A lifting height cable detection device is provided, including an A-beam, a cylinder base installed at the bottom of the A-beam, a lifting cylinder installed on the cylinder base, and cable pulling mechanisms installed on both sides of the lifting cylinder;

[0007] The cable pulling mechanism includes two sets of control boxes. The control boxes are installed on both sides of the lifting cylinder. The control boxes are equipped with cable pulling sensors, and heavy-duty cable pulling is installed through the cable pulling sensors. The control boxes have through holes at the top and bottom for the heavy-duty cable pulling through. The control boxes are equipped with cable pulling rollers at the bottom. The two ends of the heavy-duty cable pulling are connected to the cylinder base and the A-beam, respectively.

[0008] Specifically, a support frame is installed on the pull roller, and the support frame is fixed on the lifting cylinder. Wire sleeves are installed at both the upper and lower ends of the pull roller, and heavy-duty pull wires are installed inside the wire sleeves.

[0009] Specifically, two sets of protruding blocks are vertically installed on the cylinder base and the A-beam, and connecting pull rings are installed on the protruding blocks. The two sets of connecting pull rings are fixedly connected to both ends of the heavy-duty pull cable.

[0010] Specifically, a fixed support is installed above the control box, which is fixed to the lifting cylinder, and a grooved rotating roller is movably installed on the fixed support.

[0011] Specifically, the two sets of connecting pull rings, control boxes and pull rollers are installed in the same line, and the two sets of heavy-duty pull cables are connected in parallel on both sides of the lifting cylinder.

[0012] When the A-beam is lifted by the lifting cylinder, the pull-line mechanism installed on both sides of the lifting cylinder can detect the displacement of the heavy-duty pull-line through the pull-line sensor. The pull-line sensor converts the displacement distance detection into an electrical signal for transmission. The pull-line roller and grooved rotating roller installed at the upper and lower ends of the lifting cylinder can play an auxiliary role in the heavy-duty pull-line to ensure the accuracy of the heavy-duty pull-line movement, and improve the accuracy and convenience of detection.

[0032] The present invention will be further described in conjunction with the following embodiments. Example

[0033] like Figure 1-3 As shown, a lifting height cable detection device includes an A-beam 1, a cylinder base 2 installed at the bottom of the A-beam 1, a lifting cylinder 3 installed on the cylinder base 2, and cable pulling mechanisms 4 installed on both sides of the lifting cylinder 3.

[0034] The A-beam 1 has a lifting cylinder 3 installed at the center of the bottom for lifting. During the lifting process of the A-beam 1, the lifting height is detected by the cable mechanism 4 installed on the lifting cylinder 3. The cylinder base 2 installed at the bottom of the lifting cylinder 3 can provide support for the lifting cylinder 3 and ensure the stability of the lifting cylinder 3 during lifting.

[0035] The cable pulling mechanism 4 includes two sets of control boxes 5. The control boxes 5 are installed on both sides of the lifting cylinder 3. The control boxes 5 are equipped with cable pulling sensors 6. Heavy-duty cable 7 is installed through the cable pulling sensors 6. The control boxes 5 have through holes at the top and bottom for the heavy-duty cable 7 to pass through. The control boxes 5 are equipped with cable pulling rollers 8 at the bottom. The two ends of the heavy-duty cable 7 are connected to the cylinder base 2 and the A-beam 1 respectively.

[0036] The two sets of control boxes 5 are equipped with a pull cable sensor 6 with a threaded hub inside. This hub is connected to a precision rotation sensor. A heavy-duty pull cable 7 is wound on the hub. During the movement of the pull cable, the rotation sensor transmits a movement electrical signal to the outside. During the lifting process, the lifting cylinder 3 can drive the heavy-duty pull cable 7. When the heavy-duty pull cable 7 moves, it can rotate and extend on the pull cable roller 8. When the heavy-duty pull cable 7 moves, it is detected by the pull cable sensor 6 inside the control box 5 and the lifting height is displayed.

[0037] A support frame 9 is installed on the pull roller 8, and the support frame 9 is fixed on the lifting cylinder 3. Wire sleeves 10 are installed at the upper and lower ends of the pull roller 8. Heavy-duty pull wire 7 is installed inside the wire sleeves 10. The support frame 9 fixes the pull roller 8 on the lifting cylinder 3. Several turns of heavy-duty pull wire 7 are wound on the pull roller 8. The wire sleeves 10 at the upper and lower ends of the pull roller 8 can protect the heavy-duty pull wire 7. The rotation of the pull roller 8 is controlled by an external rotation mechanism to wind the heavy-duty pull wire 7.

[0038] Two sets of protruding blocks 11 are vertically installed on the cylinder base 2 and the A-beam 1. Connecting pull rings 12 are installed on the protruding blocks 11. The two sets of connecting pull rings 12 are fixedly connected to both ends of the heavy-duty pull line 7. The protruding blocks 11 are installed on the cylinder base 2 and the A-beam 1 to ensure that the heavy-duty pull line 7 is installed vertically to ensure the accuracy of the pull line detection. The heavy-duty pull line 7 is fixedly connected through the connecting pull rings 12. After the A-beam 1 is lifted, the heavy-duty pull line 7 is stretched.

[0039] A fixed support 13 is installed above the control box 5. The fixed support 13 is fixed on the lifting cylinder 3. A grooved rotating roller 14 is movably installed on the fixed support 13. The grooved rotating roller 14 rotatably installed on the fixed support 13 can support the bottom of the heavy-duty pull wire 7. During the movement of the heavy-duty pull wire 7, it can prevent the pull wire from deviating and ensure the accuracy of the detection.

[0040] Two sets of connecting pull rings 12, control box 5 and pull roller 8 are installed in the same line. Two sets of heavy-duty pull cables 7 are connected in parallel on both sides of lifting cylinder 3. The co-line installation avoids the heavy-duty pull cables 7 from shifting during the pulling process, thus improving the accuracy of lifting height detection.

[0041] During the production process, when the A-beam 1 is lifted by the lifting cylinder 3, the wire pulling mechanism 4 installed on both sides of the lifting cylinder 3 can detect the displacement of the heavy-duty wire 7 through the wire pulling sensor 6. The wire pulling sensor 6 converts the displacement distance detection into an electrical signal for transmission. The wire pulling roller 8 and the grooved rotating roller 14 installed at the upper and lower ends of the lifting cylinder 3 can play an auxiliary role in the heavy-duty wire 7 to ensure the accuracy of the movement of the heavy-duty wire 7 and improve the accuracy and convenience of detection.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
