Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a pressure roller hanger that is easy to install. Background Technology

[0002] The support roller gantry is a key support component in equipment such as aerial ropeways and wire rope transmission systems in mines. It is mainly used to fix the support roller and the pressure roller. As an aerial ropeway system, the monkey car is widely used in underground mines such as coal mines and metal mines, and is an important means of transportation for miners to go up and down the mine.

[0003] A search revealed a Chinese patent document, publication number CN212289813U, which discloses an easy-to-install pressure roller hanger, belonging to the field of mining equipment technology. It includes a fixed base and a first fixed rod fixedly connected to the fixed base. A photoelectric switch bracket is provided on one side of the first fixed rod, and a rope-supporting wheel is fixedly connected to one end of the first fixed rod. A second fixed rod is provided on the other side of the first fixed rod, with a rope-pressing wheel fixedly connected to one end of the second fixed rod. An alarm base is fixedly connected to the bottom of the second fixed rod, and a buckle is provided on the top of the fixed base. The arrangement of the first cylindrical pin, the second cylindrical pin, the first cylindrical pin fixing seat, and the second cylindrical pin fixing seat makes it easier to install the hanger by rotating the buckle on the fixed base. The buckle also increases the contact area with the steel beam, making the fixation more secure. The photoelectric switch and the audible and visual alarm enable timely detection of rope drops.

[0004] However, the above-mentioned technologies still have certain shortcomings. For example, they cannot constrain the rotation direction of the rope support wheel and the rope pressure wheel. When the rope support wheel or the rope pressure wheel reverses due to sudden load changes or external interference, the wire rope may become loose or derailed, thereby reducing the stability and safety of the wire rope during transmission and increasing maintenance costs and downtime. To address these issues, we provide an easy-to-install rope support wheel hanger. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an easy-to-install pressure roller hanger.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure roller hanger that is easy to install, comprising a steel column, on which multiple mounting holes are provided, and an installation mechanism is threadedly connected to the inside of the mounting holes. An installation plate is fixedly connected to one side of the installation mechanism, and multiple rotating rods are rotatably connected to the inside of the installation plate. Multiple receiving frames are fixedly connected to one side of the installation plate, and a limit mechanism is provided inside the receiving frames. A pressure rope wheel, a first support rope wheel, and a second support rope wheel are fixedly connected to the outer wall of the rotating rods, and two steel wire ropes are respectively provided between the pressure rope wheel and the second support rope wheel. One of the steel wire ropes is driven between the pressure rope wheel and the first support rope wheel, and the other steel wire rope is driven between the first support rope wheel and the second support rope wheel.

[0007] The aforementioned limiting mechanism includes a pawl, a ratchet, a spring, and a fixed post. One end of the pawl engages with the tooth groove of the ratchet, and the other end of the pawl is fixedly connected to the outer wall of the fixed post. The outer wall of the pawl is fixedly connected to one end of the spring.

[0008] As described above, the interior of the ratchet is fixedly connected to the outer wall of the rotating rod, and a fixing block is fixedly connected to the end of the spring away from the pawl.

[0009] As described above, both ends of the fixing block are fixedly connected to the inner wall of the receiving frame, and both ends of the fixing column are rotatably connected to the inner wall of the receiving frame.

[0010] As described above, the mounting mechanism includes a mounting base, mounting rings, bolts, and nuts. One side of the mounting base is hinged to one end of each of the two mounting rings, and the ends of the two mounting rings away from the mounting base are inserted into each other. The bolts and nuts are threaded together.

[0011] As described above, one end of the bolt passes through the mounting plate, mounting base, steel column and mounting ring in sequence and extends to the outside of the nut.

[0012] As mentioned above, an audible and visual alarm and a photoelectric switch are fixedly connected to one side of the mounting plate, and the photoelectric switch is an E3JK-DR11-C photoelectric switch.

[0013] Compared with existing technologies, this easy-to-install roller support bracket has the following advantages:

[0014] I. This utility model utilizes a rotating rod to drive a ratchet to rotate clockwise, allowing the pawl to slide through the ratchet tooth groove and rotate. When rotating counterclockwise, the pawl engages in the tooth groove to prevent reverse rotation, achieving unidirectional limiting. The fixing block constantly compresses the spring, continuously applying elastic force towards the tooth groove to the pawl, ensuring tight engagement with the ratchet and timely return to its locked position. The fixing post at one end of the pawl is rotatably connected to the inner wall of the receiving frame, ensuring flexible rotation of the pawl. This mechanism can prevent accidental reverse rotation of the equipment, avoid wire rope slippage, improve operational safety in hoisting and conveying scenarios, and reduce the accident rate.

[0015] II. During equipment installation, the mounting ring rotates to form a ring-shaped structure that wraps around the steel column. Then, bolts are used to pass through the mounting plate, mounting base, steel column, and mounting ring, and nuts are used to fix them in place. The steel column has multiple mounting holes to adjust the height of the device. In addition, photoelectric switches monitor the status of the rope pressing wheel, rope supporting wheel one, rope supporting wheel two, and related equipment in real time. When the wire rope comes loose, the audible and visual alarm starts flashing lights and sounds an alarm, which helps to remind on-site operators to deal with abnormal situations in a timely manner and prevent accidents from escalating.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4As shown, this utility model provides a technical solution: an easy-to-install pressure roller hanger, including a steel column 1, with multiple mounting holes 2 on the steel column 1, and a mounting mechanism 3 threadedly connected inside the mounting holes 2. A mounting plate 4 is fixedly connected to one side of the mounting mechanism 3, and multiple rotating rods 5 are rotatably connected inside the mounting plate 4. Multiple receiving frames 6 are fixedly connected to one side of the mounting plate 4, and a limit mechanism 7 is provided inside the receiving frame 6. A pressure rope wheel 8, a first supporting rope wheel 9, and a second supporting rope wheel 10 are fixedly connected to the outer wall of the rotating rod 5, and two steel wire ropes 11 are respectively provided between the pressure rope wheel 8 and the second supporting rope wheel 10. One steel wire rope 11 is driven between the pressure rope wheel 8 and the first supporting rope wheel 9, and the other steel wire rope 11 is driven between the first supporting rope wheel 9 and the second supporting rope wheel 10.

[0024] When the wire ropes 11 are in operation, the two wire ropes 11 are driven by the pressure wheel 8 and the first and second support wheels 9 and 10 respectively. At this time, the pressure wheel 8 and the first support wheel 9 rotate on the mounting plate 4 through the rotating rod 5, which in turn drives the limiting mechanism 7 to rotate. When the rotating rod 5 rotates clockwise, the limiting mechanism 7 allows the rotating rod 5 to rotate. However, when the pressure wheel 8, the first support wheel 9, or the second support wheel 10 attempts to rotate counterclockwise through the rotating rod 5, the limiting mechanism 7 will engage in the tooth groove to prevent it from reversing, thus achieving a one-way limiting function. This mechanism prevents the pressure wheel 8, the first support wheel 9, or the second support wheel 10 from accidentally reversing during operation, avoiding the risk of the wire rope 11 slipping due to reversal, improving the operational safety in hoisting and conveying scenarios, and reducing the occurrence of accidents. Next, during equipment installation, the two mounting rings 302 rotate to form a ring-shaped structure that wraps around the steel column 1. Then, the installation mechanism 3 is used to fix it to the steel column 1. The installation is carried out by hinged connection of the mounting rings 302. The entire installation process is simple to operate and suitable for quick on-site installation and adjustment. The steel column 1 has multiple mounting holes 2, which can adjust the height of the device. In addition, when the rope support wheel, rope pressure wheel 8 or other load-bearing objects are abnormal, the photoelectric switch 14 acts as a detection element to monitor the status of the rope pressure wheel 8, rope support wheel 1 9, rope support wheel 2 10 and related equipment in real time. When the wire rope 11 comes loose, the audible and visual alarm 13 starts to flash lights and sound an alarm, which can help remind on-site operators to deal with abnormal situations in time and prevent accidents from escalating.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, the limiting mechanism 7 includes a pawl 701, a ratchet 702, a spring 703, and a fixing post 704. One end of the pawl 701 is engaged with the tooth groove of the ratchet 702, and the other end of the pawl 701 is fixedly connected to the outer wall of the fixing post 704. The outer wall of the pawl 701 is fixedly connected to one end of the spring 703. The inside of the ratchet 702 is fixedly connected to the outer wall of the rotating rod 5. A fixing block 12 is fixedly connected to the end of the spring 703 away from the pawl 701. Both ends of the fixing block 12 are fixedly connected to the inner wall of the receiving frame 6. Both ends of the fixing post 704 are rotatably connected to the inner wall of the receiving frame 6.

[0026] When the lever 5 drives the ratchet 702 to rotate clockwise, the pawl 701 can slide over the teeth of the ratchet 702, allowing rotation. However, when the rope-pressing wheel 8, rope-supporting wheel 19, or rope-supporting wheel 20 attempts to rotate the ratchet 702 counterclockwise via the lever 5, the pawl 701 will engage in the tooth groove, preventing it from reversing, thus achieving a one-way limiting function. Furthermore, the fixing block 12 constantly compresses the spring 703, ensuring it always applies a spring force towards the tooth groove of the ratchet 702 to the pawl 701, keeping the pawl 701 engaged with the ratchet 702. The tight engagement of 2 ensures that the pawl 701 can return to its original position and lock the ratchet 702 in time during the rotation of the rotating rod 5, preventing loosening or reverse rotation. Both ends of the fixed column 704 are rotatably connected to the inner wall of the receiving frame 6, ensuring the flexible rotation of the pawl 701. This mechanism prevents the pressure rope wheel 8, the first rope support wheel 9, or the second rope support wheel 10 from accidentally reversing during operation, avoiding risks such as slippage of the wire rope 11 caused by reversal, improving the operational safety in hoisting and conveying scenarios, and reducing the accident rate.

[0027] like Figure 1 and Figure 3 As shown, the mounting mechanism 3 includes a mounting base 301, a mounting ring 302, a bolt 303, and a nut 304. One side of the mounting base 301 is hinged to one end of each of the two mounting rings 302, and the ends of the two mounting rings 302 away from the mounting base 301 are inserted into each other. The bolt 303 is threadedly connected to the nut 304. One end of the bolt 303 passes through the mounting plate 4, the mounting base 301, the steel column 1, and the mounting ring 302 in sequence and extends to the outside of the nut 304. An audible and visual alarm 13 and a photoelectric switch 14 are fixedly connected to one side of the mounting plate 4, and the photoelectric switch 14 is an E3JK-DR11-C photoelectric switch.

[0028] During equipment installation, the two mounting rings 302 rotate to form a ring-shaped structure that wraps around the steel column 1. Then, bolts 303 are sequentially passed through the mounting plate 4, mounting base 301, steel column 1, and mounting rings 302, extending to the outside of the mounting rings 302. Next, nuts 304 are used to fix the bolts 303. The mounting rings 302 are used for hinged installation. The entire installation process is simple and suitable for quick on-site installation and adjustment. The steel column 1 has multiple mounting holes 2, which can adjust the height of the device. In addition, when the rope-supporting wheel, the rope-pressing wheel 8, or other load-bearing objects malfunction, the photoelectric switch 14 acts as a detection element to monitor the status of the rope-pressing wheel 8, the first rope-supporting wheel 9, the second rope-supporting wheel 10, and related equipment in real time. When the wire rope 11 comes loose, the audible and visual alarm 13 starts flashing lights and sounds an alarm, which helps to remind on-site operators to deal with abnormal situations in a timely manner and prevent accidents from escalating.

[0029] Working principle: When the wire rope 11 is working, the two wire ropes 11 are driven by the pressure wheel 8 and the first and second support wheels 9 and 10 respectively. At this time, the pressure wheel 8 and the first support wheel 9 rotate on the mounting plate 4 through the rotating rod 5, which in turn drives the ratchet 702 to rotate. When the rotating rod 5 drives the ratchet 702 to rotate clockwise, the pawl 701 can slide over the tooth surface of the ratchet 702, allowing rotation. When the pressure wheel 8, the first support wheel 9, or the second support wheel 10 rotates through the rotating rod 5... When the ratchet 702 attempts to rotate counterclockwise, the pawl 701 engages in the tooth groove, preventing it from reversing, thus achieving a one-way limiting function. The fixing block 12 constantly compresses the spring 703, applying a spring force towards the tooth groove of the ratchet 702 to the pawl 701, ensuring a tight engagement between the pawl 701 and the ratchet 702. This ensures that during the rotation of the lever 5, the pawl 701 can promptly return to its original position and lock onto the ratchet 702, preventing loosening or reversal. The two sides of the fixing post 704... All ends are rotatably connected to the inner wall of the receiving frame 6, ensuring the flexible rotation of the pawl 701. This mechanism prevents the pressure rope wheel 8, the first rope support wheel 9, or the second rope support wheel 10 from accidentally reversing during operation. Then, during equipment installation, the two mounting rings 302 rotate to form a ring-shaped structure that wraps around the steel column 1. Subsequently, bolts 303 are passed through the mounting plate 4, mounting base 301, steel column 1, and mounting rings 302 in sequence and extend to the outside of the mounting rings 302. Then, nuts 304 are used to fix the bolts 303. The mounting rings 302 are hinged for wrapping installation. The steel column 1 has multiple mounting holes 2 to adjust the height of the device. In addition, when the rope support wheel, pressure rope wheel 8, or other load-bearing objects malfunction, the photoelectric switch 14 acts as a detection element to monitor the status of the pressure rope wheel 8, the first rope support wheel 9, the second rope support wheel 10, and related equipment in real time. When the wire rope 11 comes loose, the audible and visual alarm 13 starts flashing lights and sounds an alarm.
