Description

Technical Field

[0001] This utility model relates to the field of AA technology, specifically a belt conveyor tensioning cylinder head fixing device. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device, has no transmission backlash, and provides smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a cushioning device, and a venting device.

[0003] Patent CN219062118U discloses a cylinder piston rod head fixing device, relating to the field of bending roller technology. The technical solution includes a fixing block and a cylinder. The fixing block has a placement groove, within which an anti-rotation device is placed. The anti-rotation device includes an upper limit block and a lower limit block. The lower end of the upper limit block has an upper limit groove, and the upper end of the lower limit block has a lower limit groove. The top of the upper limit groove and the bottom of the lower limit groove are both arc-shaped. The beneficial effects of this technical solution are: through the cooperation of the upper limit groove, lower limit groove, and connecting column, the cylinder piston rod is limited, avoiding damage to the displacement sensor caused by the rotation of the cylinder piston rod. It also reduces spare parts procurement costs, minimizes unplanned downtime due to displacement sensor replacement, and improves equipment availability.

[0004] When using a belt conveyor, a tensioning cylinder is used to adjust the belt tension. A fixing device secures the cylinder head to the machine. However, the fixing device in the aforementioned patent can only fix cylinder heads of the same specification. When it is necessary to replace the tensioning cylinder with a different specification, the fixing device needs to be adjusted again, which increases the difficulty of operation and reduces the efficiency of tensioning cylinder replacement and maintenance. To address these issues, we provide a belt conveyor tensioning cylinder head fixing device. Utility Model Content

[0025] The positioning ring 204 is fixedly connected to the surface of the adjusting base 201. The internal thread of the positioning ring 204 is connected to the adjusting bolt 206. The surface of the mounting plate 1 is provided with equidistant positioning grooves 205, and the adjusting bolt 206 is inserted into the positioning groove 205. The top of the adjusting bolt 206 is an internal hexagonal groove, which makes it convenient for maintenance personnel to use power tools to rotate the adjusting bolt 206. By rotating the adjusting bolt 206 on the positioning ring 204, the bottom of the adjusting bolt 206 is inserted into the positioning groove 205, thereby positioning the position of the positioning ring 204 and fixing the position of the adjusting base 201.

[0026] like Figure 3 and Figure 4As shown, a fixing mechanism 3 is provided on the surface of the adjusting base 201. The fixing mechanism 3 includes a fixing shell 301, a clamping ring 307, and a connecting plate 310. The fixing shell 301 and the connecting plate 310 are both fixedly connected to the adjusting base 201. A limiting sleeve 309 is fixedly connected to the surface of the connecting plate 310. A fixing sleeve 312 is sleeved on the surface of the limiting sleeve 309. The fixing shell 301 is used to position and protect the cylinder head of the tensioning cylinder, thereby improving the stability of the tensioning cylinder in use.

[0027] The fixed sleeve 312 is fixed by the connecting plate 310 and the limiting sleeve 309. The tension cylinder head is fixed by fitting it onto the surface of the fixed sleeve 312. The fixed sleeve 312 is positioned by the clamping ring 307, thereby fixing the tension cylinder head and improving the stability of the tension cylinder operation. When replacing the tension cylinder, if the ring of the tension cylinder head does not match the fixed sleeve 312, a fixed sleeve 312 of appropriate diameter can be replaced to fix and install tension cylinders of different specifications, improving the convenience of tension cylinder installation.

[0028] The surface of the limiting cylinder 309 is fitted with a second buffer pad 311. The bottom end of the second buffer pad 311 is fixedly connected to the connecting plate 310, and the top end of the second buffer pad 311 abuts against the fixed sleeve 312. The second buffer pad 311 buffers and positions the fixed sleeve 312, blocks and eliminates the vibration generated by the belt drive, and improves the stability of the device operation.

Move the positioning frame 302 downward and slide it outward to remove the positioning frame 302 from the inside of the fixed housing 301. Then move the adjusting plate 305 upward and replace the appropriate fixing sleeve 312 according to the inner diameter of the cylinder head. Then put the cylinder head of the tensioning cylinder on the surface of the fixing sleeve 312. Then insert the reinforcing rod 308 into the limiting cylinder 309 so that the clamping ring 307 and the cylinder head abut against each other. Then push the positioning frame 302 into the inside of the fixed housing 301 so that the positioning frame 302 and the fixed housing 301 are locked together. By rotating the fastening bolt 303, the clamping plate 304 presses the adjusting plate 305 downward.

[0033] The tension cylinder head is clamped by the clamping ring 307 and the fixing sleeve 312, and the tension cylinder head is fixedly installed inside the equipment. Loosen the adjusting bolt 206, and adjust the adjusting base 201 to a suitable position according to the length of the tension cylinder. By rotating the adjusting bolt 206, the bottom of the adjusting bolt 206 is inserted into the positioning groove 205 to fix the position of the adjusting base 201. With the above device, tension cylinders of different specifications can be fixedly installed, reducing the difficulty of replacing and installing tension cylinders and improving the maintenance efficiency of tension cylinders.
