Description

Technical Field

[0001] This utility model relates to the field of tension station tension cylinder detection technology, and in particular to a separate pressure detection device for tension station tension cylinders. Background Technology

[0002] The steel cord conveyor belt production line consists of two main parts: the main machine and the auxiliary machine. The auxiliary machine includes a spindle frame, tension station, fixed combing unit, forming car, multi-functional belt pulling unit, hydraulic belt cutting machine, winding and packaging machine, and other equipment. The tension station is a frame structure, containing clamping devices, moving devices, and a tensioning device. The tensioning device contains multiple tension cylinders, each acting on each steel cord. The tension value of the Φ2.5-Φ15mm steel cord is adjusted by changing the hydraulic pressure.

[0003] In traditional tension stations, all tension cylinders are connected to the same pipeline. Ideally, under the action of working fluid at the same pressure, the output force of each tension cylinder on each wire rope should be consistent and constant. However, in actual use, due to uncertainties such as pressure loss, it is impossible to guarantee that the tension of each tension cylinder is consistent. This design cannot detect the actual pressure of each tension cylinder, and therefore cannot detect the actual tension of each wire rope, which has a certain impact on the product quality of the wire rope conveyor belt. In order to solve the above problems, we have proposed a separate pressure detection device for tension cylinders in tension stations. Utility Model Content

[0004] The main purpose of this invention is to provide a separate pressure detection device for the tension cylinder of a tension station, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tension station tension cylinder pressure individual detection device includes a tension frame and multiple tension cylinders. The tension frame is equipped with oil pipes, and the oil pipes have multiple connecting mechanisms for connecting the tension cylinders. Each connecting mechanism includes a connecting pipe mounted on the oil pipe. The tension frame is equipped with a crossbeam, and the crossbeam has multiple tee pipes. Each tee pipe has a solenoid ball valve and a pressure sensor connected to its two ends respectively. Each tension cylinder is connected to an adjacent tee pipe. The end of the connecting pipe furthest from the oil pipe is connected to an adjacent solenoid ball valve. A control cabinet is located on the side wall of the tension frame, and the control cabinet has a cooling mechanism for reducing its temperature.

[0007] Preferably, the cooling mechanism includes an air outlet pipe installed on the control cabinet, and ventilation openings are provided on both sides of the control cabinet.

[0008] Preferably, the control cabinet has mounting cylinders on both side walls, and the side walls of the mounting cylinders are provided with dustproof nets.

[0009] Preferably, a fan is provided inside the mounting cylinder, and a dust cover is provided on the air outlet pipe.

[0010] Preferably, the mounting cylinder has a threaded mounting ring on its side wall, and the mounting ring is fixedly connected to the control cabinet.

[0011] Preferably, the mounting cylinder has a threaded connection to a connecting ring on its side wall, and the connecting ring is fixedly connected to an adjacent dustproof net.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This device is equipped with a connection mechanism. Each tension cylinder is equipped with a pressure sensor and a solenoid ball valve on the pipeline. With the cooperation of the pressure sensor and the solenoid ball valve, each tension cylinder can be individually detected and controlled. The pressure sensor feeds the signal back to the control cabinet. Under the action of the servo pump, the pressure of each tension cylinder is controlled, thereby meeting the different tension requirements of different specifications of wire rope and ensuring that the pressure of all tension cylinders is consistent.

[0014] 2. This device is equipped with a cooling mechanism. By setting ventilation channels on both sides of the bottom of the control cabinet and an air outlet channel at the top, hot air rises and cold air enters, which can cool the control cabinet and ensure its normal operation.

[0015] 3. This device is equipped with a fan, which can be turned on to accelerate the airflow inside the control cabinet when the workshop temperature is high or the equipment has been working for a long time, thereby improving the cooling effect inside the control cabinet.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, the tension station tension cylinder pressure individual detection device includes a tension frame 1 and multiple tension cylinders 9. The tension frame 1 is provided with an oil pipe 4, and the oil pipe 4 is provided with multiple connecting mechanisms for connecting the tension cylinders 9. The connecting mechanism includes a connecting pipe provided on the oil pipe 4. The tension frame 1 is provided with a crossbeam 2, and the crossbeam 2 is provided with multiple three-way pipes 6. The two ends of the three-way pipes 6 are respectively connected to an electromagnetic ball valve 5 and a pressure sensor 7. The tension cylinder 9 is connected to the adjacent three-way pipe 6. The end of the connecting pipe away from the oil pipe 4 is connected to the adjacent electromagnetic ball valve 5. The tension frame 1 is provided with a control cabinet 8 on its side wall.

[0023] The control cabinet 8 is equipped with a cooling mechanism to reduce the temperature of the control cabinet 8. The cooling mechanism includes an air outlet pipe 10 installed on the control cabinet 8, and ventilation openings 17 are provided on both sides of the control cabinet 8.

[0024] In this utility model, both sides of the control cabinet 8 are provided with mounting cylinders 13, and the side walls of the mounting cylinders 13 are provided with dustproof nets 16, which can filter the air entering the control cabinet 8 and prevent dust from entering the control cabinet 8 when there is a lot of dust in the workshop.

[0025] In this utility model, a fan 14 is provided inside the mounting cylinder 13. When the workshop temperature is high or the equipment is working for a long time, the fan 14 can be activated to accelerate the air flow in the control cabinet 8 and improve the cooling effect. A dust cover 11 is provided on the air outlet pipe 10. The dust cover 11 is connected to the air outlet pipe 10 through multiple connecting rods. A metal mesh is provided inside the air outlet pipe 10, which is not shown in the figure.

[0026] In this utility model, the side wall of the mounting cylinder 13 is threaded with a mounting ring 12, which is fixedly connected to the control cabinet 8, making the mounting cylinder 13 detachable and convenient for equipment transportation.

[0027] In this utility model, the side wall of the mounting cylinder 13 is threaded with a connecting ring 15, which is fixedly connected to the adjacent dustproof net 16, making it easier to disassemble the dustproof net 16 and to clean and replace the dustproof net 16.

[0028] It should be noted that this utility model is a pressure detection device for tension cylinders in a tension station. Each tension cylinder 9 is equipped with a pressure sensor 7 and a solenoid ball valve 5 on its pipeline. The pressure sensor 7 monitors the oil pressure in the pipeline, and the solenoid ball valve 5 controls the oil flow. With the cooperation of the pressure sensor 7 and the solenoid ball valve 5, each tension cylinder 9 can be controlled independently. The pressure sensor 7 feeds the signal back to the control cabinet 8, and under the action of the servo pump, the pressure of each tension cylinder 9 is controlled, thereby meeting the different tension requirements of wire ropes of different specifications and ensuring that the pressure of all tension cylinders 9 is consistent.
