Description

Technical Field

[0001] This utility model relates to the field of on-site positioning technology for coal mine safety production, specifically to a rotary round tail rope suspension device for mine hoisting equipment. Background Technology

[0002] A round tail rope suspension device is a specialized piece of equipment used in multi-rope hoisting systems to connect the hoisting container to the tail rope beam. Its main function is to balance the tension of the wire rope, prevent rope twisting, and ensure the smooth operation of the hoisting container. A round tail rope suspension device typically consists of upper and lower parts that rotate relative to each other via a rolling ring structure, effectively preventing the balancing wire rope from slipping or knotting on the friction wheel.

[0003] As disclosed in the prior art, CN209098002U, a double-rotating round tail rope suspension device is presented. The disclosed technical solution uses two sets of connecting sleeves to be rotatedly installed with the first or second rod to realize a rotating round tail rope suspension device. This prior art has the following drawbacks: 1. The first rod is connected in a fixed manner. In the tail rope rotation type, only the connecting sleeve rotates to avoid the problem of tail rope knotting. In practice, this structure will aggravate the wear and tear of the first or second rod. Since the component is located at the center of the round tail rope suspension device, it will increase the difficulty of maintenance. Secondly, the existing round tail rope suspension device has a relatively complex structure. There are too many parts for installation and maintenance, which is not conducive to maintenance work. Furthermore, the large number of parts increases the production cost of the device, which is not conducive to market promotion.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is necessary to provide a rotary round tail rope suspension device for mining hoisting equipment. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a rotary round tail rope suspension device for mining hoisting equipment, aiming to improve and solve the technical problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary round tail rope suspension device for mining hoisting equipment, comprising a connecting rod, a lifting rod, and a sleeve. The lifting rod is fixedly installed below the connecting rod via a pin, which is secured by a washer and a nut. The bottom of the connecting rod is configured as a sleeve, and a main shaft is configured between the connecting rod and the sleeve. Several sets of bearing sleeves are evenly distributed on the main shaft. Each bearing sleeve includes a bearing shoulder and a sleeve base. The sleeve bases of the grouped bearing sleeves that are adjacent to each other are sealed and installed by a fixed base. The fixed base is secured by an externally provided... The retaining ring is fixedly connected to the sleeve base. The bearing shoulder of the upper bearing sleeve is fixedly connected to the hanger rod via a long shaft screw. The bearing shoulder of the lower bearing sleeve is fixedly connected to the sleeve via a long shaft screw. A tail rope head is fixedly installed inside the sleeve. The inner ring of the sleeve base is rotatably installed with the main shaft via a deep groove ball bearing. The inner ring of the bearing shoulder is rotatably installed with the main shaft via a deep groove ball bearing. The inner ring of the bearing sleeve near the bearing shoulder is rotatably installed with the main shaft via a thrust bearing. The end of the bearing sleeve near the bearing shoulder is fixedly connected by a nut and a cotter pin.

[0007] Preferably, the sleeve base and the fixed base are installed using a J-type oil seal clearance fit.

[0008] Preferably, protective sleeves are used to connect the sleeve to the bearing shoulder and the hanger rod to the bearing shoulder.

[0009] Preferably, a cotter pin is provided on one side of the pin to prevent loosening of the nut during installation.

[0010] Preferably, the sleeve is secured inside by wedges and a cast alloy to fix the tail rope head.

[0011] Preferably, the end of the bearing sleeve is fixedly connected to the spindle by double washers.

[0012] Preferably, the fixing retaining rings distributed on the upper and lower sides of the fixing base are fixed and installed by bolts.

[0013] Preferably, the inner ring of the sleeve base and the deep groove ball bearing one, and the inner ring of the bearing shoulder and the deep groove ball bearing two are both sealed and protected by sealing rings.

[0014] Preferably, an oil plug and an oil seal are provided on one side of the protective sleeve.

[0015] Preferably, a set of two bearing sleeves are evenly distributed on the main shaft.

[0016] In summary, this utility model provides a rotary round tail rope suspension device for mining hoisting equipment. The round tail rope suspension device of this patent uses a connecting rod to fix the lifting rod through a pin. The lifting rod is installed with a bearing sleeve and a sleeve in sequence through a long shaft screw. The main shaft is rotatably installed inside the bearing sleeve. The main shaft is independently movable. A tail rope mounting hole is opened at the bottom of the sleeve. The tail rope head is fixedly installed inside the tail rope mounting hole by wedge clamping and casting alloy. This realizes the technical functions of flexible rotary installation of the round tail rope suspension device, avoiding high-intensity wear and tear of the main shaft, and balancing the installation of the tail rope.

[0017] This structural design allows the tail rope to rotate via deep groove ball bearings 1 and 2 and the main shaft when it is knotted or slipping on the friction wheel. This counteracts the rotation caused by the knotted tail rope. The main shaft is rotatably mounted on the bearing sleeve via a thrust bearing, enabling a self-rotating installation method that buffers the rotation of the bearing sleeve alone. This reduces the impact of fixed main shaft installation and high-strength wear installation methods in existing technologies, and solves the technical problem of high maintenance difficulty.

[0018] This patent employs a fixed base located in the middle, which is installed between two bearing sleeves and rotates with them. Through a lubrication structure, it reduces contact wear between components. Furthermore, when one deep groove ball bearing is worn and damaged, it can be rotated via the other deep groove ball bearing. When all deep groove ball bearings are damaged, only the fixed base needs to be disassembled for maintenance, and the deep groove ball bearings and bearing sleeves need to be repaired. This achieves the technical benefits of simplified maintenance procedures and reduced maintenance workload. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 2 As shown: This utility model is a rotary round tail rope suspension device for mining hoisting equipment. In order to solve the problems of increased wear and tear and difficult maintenance caused by the fixed installation method of the boom 2 and main shaft 24 in the existing technology, and to further improve the complexity of the existing round tail rope suspension device structure, so as to simplify maintenance, reduce production costs, expand market demand and increase competitiveness.

[0022] The technical solution includes: a connecting rod 1, a lifting rod 2, and a sleeve 16. The lifting rod 2 is fixedly installed below the connecting rod 1 via a pin 3. The pin 3 is fixedly installed using washers and nuts. The bottom of the connecting rod 1 is set as the sleeve 16. A main shaft 24 is set between the connecting rod 1 and the sleeve 16. Several sets of bearing sleeves 7 are evenly distributed on the main shaft 24. The bearing sleeves 7 include bearing shoulders 71 and sleeve bases 72. The sleeve bases 72 of the grouped bearing sleeves 7 that are close to each other are sealed and installed by a fixed base 73. The fixed base 73 is fixedly connected to the sleeve base 72 by an externally set fixing retaining ring 5. The upper bearing sleeve 7 is located at the top. The bearing shoulder 71 is fixedly connected to the hanger 2 via a long shaft screw 29. The bearing shoulder 71 located in the lower bearing sleeve 7 is fixedly connected to the sleeve 16 via a long shaft screw 29. The tail rope head 30 is fixedly installed inside the sleeve 16. The inner ring of the sleeve base 72 is rotatably installed with the main shaft 24 via a deep groove ball bearing 6. The inner ring of the bearing shoulder 71 is rotatably installed with the main shaft 24 via a deep groove ball bearing 8. The inner ring of the bearing sleeve 7 near the bearing shoulder 71 is rotatably installed with the main shaft 24 via a thrust bearing 10. The end of the bearing sleeve 7 near the bearing shoulder 71 is fixedly connected by a nut and a cotter pin.

[0023] The specific structural principle is as follows: The round tail rope suspension device uses a connecting rod 1 to fix the hanging rod 2 through the pin 3. The hanging rod 2 is connected to the bearing sleeve 7 and the sleeve 16 in sequence through the long shaft screw 29. The main shaft 24 is rotatably installed inside the bearing sleeve 7. The main shaft 24 is set independently. The bottom of the sleeve 16 has a tail rope mounting hole. The tail rope head 30 is fixedly installed inside the tail rope mounting hole by the wedge 17 and the alloy is cast. This realizes the technical function of flexible rotational installation of the round tail rope suspension device, avoids high-intensity wear and tear of the main shaft 24, and balances the installation of the tail rope.

[0024] The bearing sleeve 7 is installed on the spindle 24 at its center as follows: The bearing sleeve 7 includes a bearing shoulder 71 and a sleeve base 72. Preferably, two bearing sleeves 7 are installed on the spindle 24. The sleeve bases 72 on the bearing sleeve 7 are arranged adjacent to each other, with two adjacent sleeve bases 72 correspondingly sleeved on the upper and lower sides of the fixed base 73. Fixing retaining rings 5 ​​are bolted to the upper and lower sides of the fixed base 73 to limit the sleeve base 72's installation on the fixed base 73. The fixed base 73 and... A J-type oil seal 4 is installed between the gaps of the sleeve base 72 to achieve the technical function of lubrication and wear reduction during the rotation of the sleeve base 72. The inner ring of the sleeve base 72 is rotatably installed with the main shaft 24 using a deep groove ball bearing 6. The inner ring of the bearing shoulder 71 is rotatably installed with the main shaft 24 using a deep groove ball bearing 8. The inner ring of the bearing sleeve 7 at the end near the bearing shoulder 71 is rotatably installed with the main shaft 24 using a thrust bearing 10. The two ends of the main shaft 24 are fixedly installed with the bearing sleeve 7. This structural design enables the tail rope to rotate via deep groove ball bearing 6 and deep groove ball bearing 8 and main shaft 24 when the tail rope is knotted or the friction wheel is slipping. This counteracts the rotation caused by the knotted tail rope. The main shaft 24 is rotatably mounted via thrust bearing 10 and bearing sleeve 7, achieving a self-rotating mounting method for the main shaft 24. This buffers the rotation of only bearing sleeve 7, reduces the impact of the fixed mounting method and high-strength wear mounting method of the main shaft 24 in the prior art, and solves the technical problem of high maintenance difficulty. This patent employs a fixed base 73 located in the middle, which is installed between two bearing sleeves 7 and rotatably mounted with them. Through a lubrication structure, it reduces contact wear between components. Furthermore, when one deep groove ball bearing 6 is worn or damaged, the other deep groove ball bearing 6 can be rotated. When all deep groove ball bearings 6 are damaged, only the fixed base 73 needs to be disassembled and maintained to repair the deep groove ball bearings 6 and the bearing sleeves 7, thus simplifying the repair process and reducing maintenance work.

[0025] In at least one embodiment, to increase the efficiency of the spindle 24 and bearing sleeve 7 rotation and prevent foreign objects from entering and causing the rotating parts to jam, a protective sleeve 13 is used to connect the sleeve 16 and the bearing shoulder 71 and the hanger 2 and the bearing shoulder 71. By providing an oil plug 27 and an oil seal 28 on one side of the protective sleeve 13, the rotating parts are rotated by injecting lubricant, so as to achieve efficient rotation, avoid the problem of the tail rope tangling, and reduce the wear of the rotating parts.

[0026] In at least one embodiment, in order to achieve a secure and anti-loosening installation of the connecting rod 1 and the lifting rod 2, a cotter pin is provided on one side of the pin shaft 3 to prevent the nut from loosening during installation.

[0027] In at least one embodiment, the end of the bearing sleeve 7 is fixedly connected to the spindle 24 by double washers to improve the stability of the bearing sleeve 7 and the spindle 24.

[0028] In at least one embodiment, in order to increase the limiting sleeve installation of the sleeve base 72 provided at the end of the bearing sleeve 7, fixed retaining rings 5 ​​are distributed on the upper and lower sides of the fixed base 73, and the fixed retaining rings 5 ​​are fixedly installed to the fixed base 73 by bolts.

[0029] In at least one embodiment, sealing rings 9 are used to seal and protect the inner ring of the sleeve base 72 and the deep groove ball bearing 6, and the inner ring of the bearing shoulder 71 and the deep groove ball bearing 8, in order to increase the sealing protection of the deep groove ball bearing 6 and the thrust bearing 8, and to reduce wear.

[0030] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
