[0002] During the production process of a mine, the underground operation environment is complex and there are many potential safety hazards. When underground workers work in the air and the space is limited, a safety rope needs to be hung to avoid emergencies and endanger the safety of the workers.
[0003] In actual mine production activities, especially when working in a chute, workers need to wear a safety rope, and the safety rope is simultaneously hung on a hanging post. To reduce the injury suffered by workers due to falling in case of an accident, the length of the safety rope should not be too long. When construction operations at a relatively far position are required, the activities of workers are restricted, making it difficult to perform construction operations at a relatively far position. Therefore, a safety operation auxiliary device that can increase the activity range of workers without increasing the length of the safety rope during chute operation is needed. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a safety operation auxiliary structure, aiming to solve the technical problem of the small activity range when workers wear safety ropes during chute operation.

[0020] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative work fall within the scope of protection of the present utility model.
[0021] Figure 1 An embodiment of a safety operation auxiliary structure of the present utility model is shown. Refer to Figure 1 , in this embodiment, the safety operation auxiliary structure is applied to the operation of an ore pass. The safety operation auxiliary structure includes: a support rod 1 and a suspension assembly.
[0022] Among them, refer to Figure 1 , the support rod 1 is horizontally arranged, and both axial ends of the support rod 1 extend into the two sides of the drift of the ore pass; the suspension assembly is provided with a slider 2, a suspension rope 3 and a safety strap 4. The slider 2 is provided with a through hole 21. The slider 2 is sleeved outside the support rod 1 through the through hole 21. One side of the slider 2 adjacent to the bottom of the ore pass is connected to one end of the suspension rope 3. The other end of the suspension rope 3 extends towards the bottom of the ore pass and is connected to the safety strap 4. When operating in the ore pass, the staff wears the safety strap 4, and the slider 2 is sleeved on the support rod 1. Driving the slider 2 to move along the axis of the support rod 1, the activity range of the staff is increased, and construction operations at a farther position can be carried out.
[0023] Furthermore, refer to Figure 2 , the support rod 1 is further provided with a card slot 11, and at least one card slot 11 is arranged at equal intervals along the axis of the side wall of the support rod 1 adjacent to the suspension rope 3.
[0024] Furthermore, refer to Figure 2 , the suspension assembly is further provided with a limit block 5 and an elastic member 6. An installation hole 22 is provided on the inner wall of the through hole 21 adjacent to the suspension rope 3. The limit block 5 is movably installed in the installation hole 22. At least one elastic member 6 is arranged between the limit block 5 and the bottom surface of the installation hole 22. The elastic member 6 releases elastic potential energy to push the limit block 5 out of the installation hole 22. When the end of the limit block 5 away from the installation hole 22 extends into the card slot 11, the slider 2 is limited to prevent the slider 2 from sliding along the axis of the support rod 1 to prevent the slider 2 from moving during the construction process.
[0025] Furthermore, refer to Figure 2The suspension assembly is also provided with a drawstring 7. A small hole 23 connected to the mounting hole 22 is provided on one side of the slider 2 adjacent to the drawstring 3. One end of the limit block 5 away from the through hole 21 is connected to one end of the drawstring 7. The other end of the drawstring 7 extends out of the slider 2 through the small hole 23. When the drawstring 7 is pulled by an external force, the limit block 5 can be driven to retract into the mounting hole 22 and squeeze the elastic member 6. The limiting relationship between the card slot 11 and the limit block 5 is lost between the support rod 1 and the slider 2, and the slider 2 is free to move along the axial direction of the support rod 1.
[0026] Further, see Figure 2 The suspension assembly is also provided with a limit ring 8, and a limit ring 8 is provided at each preset length along the radial direction of the suspension rope 3. The end of the pull rope 7 away from the limit block 5 passes through each limit ring 8 and extends to the vicinity of the safety strap 4 to prevent the pull rope 7 from being far away from the workers during construction operations and making it difficult to control the movement of the slider 2.
[0027] Optionally, the through hole 21 has an interference fit with the support rod 1 so that the position of the slider 2 changes during the axial movement of the support rod 1; the limit block 5 has an interference fit with the mounting hole 22 to ensure that the limit block 5 can only move radially along the mounting hole 22; the end of the limit block 5 away from the pull rope 7 has an interference fit with the slot 11 to ensure that when the limit block 5 extends into the slot 11, the slider 2 cannot shake on the support rod 1.
[0028] Optionally, the elastic member 6 is a spring, one end of each spring is connected to the limiting block 5 , and the other end of each spring is connected to the bottom surface of the mounting hole 22 to prevent the limiting block 5 from detaching from the mounting hole 22 .
[0029] When the present embodiment is in use, the worker wears the safety strap 4, and when the length of the lifting rope 3 is fixed, the lifting rope 3 is pulled to drive the slider 2 to move axially along the support rod 1, which can increase the axial range of movement of the support rod 1 so as to carry out construction operations at a remote position; at the same time, when the limit block 5 extends out of the mounting hole 22 and extends into the card slot 11, the movement of the slider 2 is restricted to prevent the slider 2 from moving axially along the support rod 1 during construction operations; when it is necessary to drive the slider 2 to move, the end of the pull rope 7 away from the limit block 5 is pulled to drive the limit block 5 to retract into the mounting hole 22, and the restriction of the card slot 11 and the limit block 5 between the support rod 1 and the slider 2 is lost, and the slider 2 can be driven to slide axially along the support rod 1 again.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
