Abstract
Description
Technical Field
[0001] This utility model relates to the field of mine hoisting equipment, and in particular to a tail rope isolation device. Background Technology
[0002] In mine hoisting systems, tail rope isolation devices are used to isolate the tail rope, preventing it from becoming tangled or twisted due to its own swing or sudden stops of the hoist, thus ensuring the safe operation of the hoisting system. However, existing tail rope isolation devices have a dense internal structure, and falling rocks easily accumulate in the gaps of the rope-blocking structure during operation, reducing the tail rope's movement space. This leads to frequent contact and wear between the tail rope and the rope-blocking structure, resulting in problems such as short service life, severe wear, and low safety. There is even a risk of the tail rope being damaged and broken by friction with rocks. Therefore, designing a tail rope isolation device with a long service life and high safety is particularly urgent. Utility Model Content
[0003] The purpose of this invention is to provide a tail rope isolation device to solve the problems existing in the prior art and improve the service life and safety of the tail rope isolation device.
[0004] To achieve the above objectives, this utility model provides the following solution:
[0005] This utility model provides a tail rope isolation device, comprising:
[0006] Includes support frame and rope guide roller assembly;
[0007] The rope-blocking roller assembly is rotatably connected to the support frame via a rotating shaft and is divided into three layers in the vertical direction. One layer has a rope-blocking roller 1 parallel to the horizontal plane, another layer has a rope-blocking roller 2 parallel to the horizontal plane, and the third and fourth rope-blocking rollers are parallel to each other and located on the same horizontal plane.
[0008] The projections of the rope-blocking roller 1, rope-blocking roller 2, rope-blocking roller 3, and rope-blocking roller 4 on the horizontal plane form a rectangle, which is used to isolate the tail rope and limit its swing range.
[0009] The number of rope-blocking rollers is set in a one-to-one correspondence with the number of tail ropes.
[0010] Furthermore, the top layer of the rope-blocking roller assembly is provided with rope-blocking roller one, the middle layer is provided with rope-blocking roller three and rope-blocking roller four, and the bottom layer is provided with rope-blocking roller two.
[0011] Furthermore, the axes of the rope-blocking roller three and the rope-blocking roller four are parallel to the distribution direction of the tail rope.
[0012] Furthermore, when multiple rope-blocking roller groups are provided, all rope-blocking roller groups share rope-blocking roller three and rope-blocking roller four.
[0013] Furthermore, when multiple rope-blocking roller groups are set, the projections of all rope-blocking roller one and rope-blocking roller two on the same horizontal plane are alternately distributed.
[0014] Furthermore, the support frame includes a support plate, on which a horizontally open groove 1 is formed, and an upward-opening groove 2 is formed in the groove 1, so that the groove 1 and the groove 2 form an L-shaped anti-detachment groove. The two ends of the rope-blocking roller assembly shaft are respectively embedded in the corresponding groove 2 and fastened with nuts.
[0015] Furthermore, the groove is provided in multiple places along the height direction of the support plate, for adjusting the vertical spacing of the rope-blocking roller group.
[0016] Furthermore, multiple grooves are provided at horizontal intervals within the first groove for adjusting the horizontal spacing of the rope-blocking roller assembly.
[0017] Furthermore, an elastic buffer pad is embedded in the second groove.
[0018] Furthermore, the outer wall of the rope-blocking roller assembly is fitted with a replaceable wear-resistant protective sleeve.
[0019] The present invention achieves the following technical advantages over the prior art:
[0020] This utility model discloses a tail rope isolation device. Since the rope-blocking roller group is rotatably connected to the support frame via a rotating shaft, the rotation of the rope-blocking rollers in the rope-blocking roller group makes it easier for stones to slide off the rope-blocking roller group, reducing the sliding friction between the rope-blocking roller group and the tail rope, and reducing the wear between the rope-blocking roller group and the tail rope. By arranging rope-blocking roller one, rope-blocking roller two, rope-blocking roller three, and rope-blocking roller four in layers, a layered staggered tail rope isolation device is formed. This increases the internal gap of the rope-blocking roller group without affecting the horizontal isolation effect on the tail rope, making it easier for stones falling in the mine to pass through the rope-blocking roller group. This avoids the problem of the tail rope frequently contacting and wearing with the rope-blocking roller group and stones due to the reduced movement space of the tail rope caused by the accumulation of stones on the rope-blocking roller group, effectively improving the service life and safety of the tail rope isolation device.

[0027] 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.
[0028] The purpose of this invention is to provide a tail rope isolation device to solve the problems existing in the prior art and improve the service life and safety of the tail rope isolation device.
[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figures 1-4 As shown, this utility model provides a tail rope isolation device, including a support frame 1 and a rope-blocking roller assembly. The rope-blocking roller assembly is rotatably connected to the support frame 1 via a rotating shaft, and is arranged in three layers in the vertical direction. Two layers are respectively provided with a rope-blocking roller 31 and a rope-blocking roller 32 parallel to the horizontal plane, and the other layer is provided with a rope-blocking roller 33 and a rope-blocking roller 34 parallel to each other and located on the same horizontal plane. The projections of the rope-blocking rollers 31, 32, 33, and 44 on the horizontal plane form a rectangle, and the tail rope 2 passes through the rectangular space, thereby isolating the tail rope 2 and limiting its swing range. The number of rope-blocking roller assemblies corresponds one-to-one with the number of tail ropes 2.
[0031] Since the rope-blocking roller assembly is rotatably connected to the support frame 1 via a rotating shaft, the rotation of the rope-blocking rollers in the assembly makes it easier for stones to slide off the assembly, reducing the sliding friction between the rope-blocking roller assembly and the tail rope 2, and reducing wear between the rope-blocking roller assembly and the tail rope 2. By arranging the rope-blocking rollers 31, 32, 33, and 34 in layers, a layered staggered tail rope isolation device is formed. This increases the internal gap of the rope-blocking roller assembly without affecting the isolation effect on the tail rope 2, making it easier for stones falling in the mine to pass through the rope-blocking roller assembly. This avoids the problem of the tail rope 2 frequently contacting and wearing with the rope-blocking roller assembly and stones due to the accumulation of stones on the rope-blocking roller assembly, thus effectively improving the service life and safety of the tail rope isolation device.
[0032] As an example of an implementable approach, such as Figures 1-4 As shown, a first rope-blocking roller 31 is installed at the top of the rope-blocking roller assembly, rope-blocking rollers 33 and 44 are installed in the middle layer, and rope-blocking roller 2 32 is installed at the bottom. The axes of rope-blocking rollers 33 and 44 are arranged parallel to the direction of the tail rope 2, maximizing the spacing between rope-blocking rollers 31 and 22, which facilitates the passage of stones. Rope-blocking rollers 31 and 22 are the main rollers, while rope-blocking rollers 33 and 44 are auxiliary rollers. When multiple rope-blocking roller assemblies are set, all rope-blocking roller assemblies share rope-blocking rollers 33 and 44, i.e., they share auxiliary rollers, making the overall structure simpler. When multiple rope-blocking roller assemblies are set, the projections of all rope-blocking rollers 31 and 22 on the same horizontal plane are alternately distributed, i.e., the main rollers are arranged sequentially and alternately in the horizontal direction, avoiding the main rollers on the same layer being too close together, which further facilitates the passage of stones.
[0033] As an example of an implementable approach, such as Figure 1 , Figure 3 , Figure 4 As shown, the support frame 1 includes a support plate 11. A groove with a horizontal opening is provided on the support plate 11, and a groove with an upward opening is provided in the groove. The groove and the groove form an L-shaped anti-detachment groove 12. The two ends of the rope-blocking roller assembly shaft are respectively embedded into the corresponding grooves in the grooves and tightened with nuts. During installation, the shaft of the rope-blocking roller assembly is slid from the groove in the groove into the groove in the groove, making installation more convenient. At the same time, the groove in the groove limits the shaft of the rope-blocking roller assembly in the horizontal direction, effectively preventing the rope-blocking roller from loosening and falling off. Meanwhile, the groove in the groove limits the shaft of the rope-blocking roller assembly in the vertical direction, effectively preventing the rope-blocking roller from flying out of the support plate 11 after loosening, thus improving the safety of the tail rope isolation device.
[0034] As an example of implementation, multiple grooves are arranged along the height direction of the support plate 11 to facilitate adjustment of the vertical spacing of the rope-blocking roller group. Multiple grooves are also arranged horizontally at intervals within grooves one to adjust the horizontal spacing of the rope-blocking roller group. This adjustable spacing allows the tail rope isolation device to be adjusted according to different equipment or working conditions, increasing the compatibility of the tail rope isolation device.
[0035] As an example of implementation, an elastic buffer pad is embedded in the second groove. The elastic buffer pad can be made of polyurethane or rubber, which plays a role in shock absorption for the rope guide roller assembly. A replaceable wear-resistant protective sleeve is fitted on the outer wall of the rope guide roller assembly. The rope guide roller assembly includes rope guide roller 1 31, rope guide roller 2 32, rope guide roller 33 and rope guide roller 4 34. The wear-resistant protective sleeve can be made of polyurethane or rubber, which plays a role in protecting the tail rope 2 and the rope guide roller assembly.
[0036] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
