Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of car tipping machine equipment and relates to a lever-type car pressing detection device. Background Art
[0002] Before unloading the car body, the tipping machine must use the hydraulic system to press the hook down on the car body to fix the car body and prevent the car body from leaving the trolley track and derailing during the flipping process, causing damage to the car body and the tipping machine. The outdoor temperature in northern winter is around -20℃. If the hydraulic system of the tipping machine does not operate for a long time, it is easy to cause the hydraulic oil fluidity to decrease and the car body cannot be pressed into place within the specified time. If the car is tipped at this time, the hook will not be pressed into place and the car body cannot be fixed, resulting in derailment, damaging the car body and other corresponding equipment, and causing greater losses.

[0017] The utility model is described in detail below with reference to the accompanying drawings:
[0018] like Figure 1 and 2As shown, a lever-type car pressing detection device includes a car pressing hook 1. The car pressing hook 1 adopts an existing conventional car tipping machine car pressing hook. The car pressing hook 1 is provided with a connecting frame 2, and the connecting frame 2 is provided with a horizontally arranged support shaft 3. The support shaft 3 is provided with a rotatable sleeve 4. The side wall of the sleeve 4 is provided with a detection rod 5 and a shift rod 6. The detection rod 5 and the shift rod 6 are located in the same horizontal plane, and the detection rod 5 and the shift rod 6 form an angle of 90-120 degrees. In addition, the detection rod 5 and the shift rod 6 are arranged perpendicular to each other with the sleeve 4, and the weight of the detection rod 5 is greater than that of the shift rod 6. When the pressing coupler 1 presses the top of the car body, the detection rod 5 contacts the top of the car body, and as the pressing coupler 1 moves downward, the detection rod 5 rotates upward, and at the same time, the driving rod 6 is driven to rotate through the sleeve 4. The pressing coupler 1 is provided with a first limiting rod 7 and a second limiting rod 8. The first limiting rod 7 and the second limiting rod 8 are located on one side of the pressing coupler 1, and the driving rod 6 is located between the first limiting rod 7 and the second limiting rod 8. The first limiting rod 7 and the second limiting rod 8 are used to limit the rotation angle of the driving rod 6. When the detection rod 5 is not in contact with the top of the car body, the driving rod 6 and the first limiting rod 8 are The limit rod 7 contacts to prevent the detection rod 5 from being in a vertical state under the action of gravity, which affects normal use. A pressure sensor 9 is provided on the second limit rod 8, and a circular pressing block 10 corresponding to the pressure sensor 9 is provided on the end of the shift rod 6 away from the sleeve 4. When the detection rod 5 rotates to the corresponding position during the detection process, the pressing block 10 of the shift rod 6 contacts the pressure sensor 9 and can apply corresponding pressure to the pressure sensor 9. When the applied pressure reaches the set value, the pressure applied by the pressing coupler 1 on the top of the car body corresponds to the pressure applied by the pressing block 10 on the pressure sensor 9, indicating that the pressing coupler 1 applies sufficient pressure to the car body to complete the locking of the car body. The pressure sensor 9 is connected to a controller 11, and the pressure sensor 9 can transmit the detected pressure value to the controller 11. The controller 11 can adopt an existing conventional PLC controller. The controller 11 is connected to an indicator light 12, which is set on one side of the pressing coupler 1. When the pressure value detected by the pressure sensor 9 meets the setting, the controller 11 controls the indicator light 12 to light up, prompting the on-site operator to complete the locking of the pressing coupler 1 and perform the tipping operation.
[0019] The usage of this utility model is as follows:
[0020] When the dumper is operating to lock the car body, the coupler 1 moves downward, and the detection rod 5 moves downward accordingly. When the detection rod 5 contacts the top of the car body 13, as the coupler 1 moves downward, the detection rod 5 rotates upward, and the sleeve 4 and the lever 6 are driven to rotate through the detection rod 5. The lever 6 leaves the first limit rod 7 and rotates toward the second limit rod 8. When the coupler 1 contacts the top of the car body 13, the pressing block 10 at one end of the lever 6 contacts the pressure sensor 9. Figure 3As shown, as the pressure applied by the pressing coupler 1 to the top of the car body 13 increases, the external force applied by the pressing block 10 to the pressure sensor 9 increases. When the pressure sensor 9 detects that the pressure applied by the pressing block 10 reaches the set value, it means that the pressing coupler 1 has clamped the car body 13 firmly. At this time, the controller 11 controls the indicator light 12 to light up, prompting the on-site operator to perform the overturning operation, effectively preventing the car body from being flipped over when the pressing coupler 1 is not clamped, thereby causing a safety accident.
