Description

Technical Field

[0001] This utility model relates to the field of ladder technology, and in particular to a tail rope isolation device for the ladder at the bottom of a main shaft. Background Technology

[0002] A ladder room refers to a compartment inside a shaft specifically designed for personnel to ascend and descend using ladders. It primarily serves as a safety exit for personnel to escape in the event of an underground accident, and can also be used for repairing shaft equipment and handling jammed containers. It consists of components such as a platform, safety railings, and ladder beams. In vertical shafts, ladder rooms are required in various situations, such as hoisting shafts, ventilation shafts, working area footpaths, and other footpaths that serve as safety exits. These facilities are generally made of steel components, but nowadays, fiberglass is widely used for corrosion protection.

[0003] However, during construction, a large amount of dust falls into the ladder area. The dust accumulates on the ladder steps and handrails, making the surface slippery and increasing the risk of people slipping and falling while climbing, which seriously threatens personal safety. Long-term accumulation of dust will adhere to the surface of the ladder's metal structure, accelerate metal corrosion, shorten the ladder's service life, and increase replacement and maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where a large amount of dust falls into the ladder compartment during construction, and the dust accumulates on the ladder steps and handrails, which easily leads to slippery surfaces, increases the risk of people slipping and falling while climbing, seriously threatens personal safety, and long-term accumulation of dust will adhere to the surface of the ladder's metal structure, accelerate metal corrosion, shorten the ladder's service life, and increase replacement and maintenance costs. Therefore, a tail rope isolation device for the ladder compartment at the bottom of the main shaft is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tail rope isolation device for the ladder section at the bottom of a main shaft, comprising a shaft wall, a guardrail, and a separation device. The guardrail is fixedly installed in the inner wall of the shaft wall. The separation device is disposed on the upper surface of the shaft wall. The separation device includes a baffle plate, which is fixedly connected to the upper surface of the shaft wall. An outlet is formed on the surface of the baffle plate. A round rod is rotatably connected to the outlet on the surface of the baffle plate. A sealing plate is fixedly connected to the surface of the round rod. A stop block is fixedly connected to the lower surface of the sealing plate. The stop block... The baffles abut against each other, and a locking block is fixedly connected to the lower surface of the baffles. The locking block has a locking groove on its surface. A rotating rod is fixedly connected to the lower surface of the sealing plate. A disc is rotatably connected to the surface of the rotating rod. The disc engages with the locking groove on the surface of the locking block. By setting a separation device, dust and debris can be prevented from entering. The operator can enter and exit through the outlet by rotating the disc and pulling down the sealing plate. The sealing plate can be rotated inward to open, which can reduce the difficulty of opening when there is an object pressing down on it. This achieves the effects of sealing and dust prevention, facilitating personnel entry and exit, and flexible opening.

[0006] Preferably, there are two stops, which are symmetrically arranged. The surface of the disc has a notch, and the locking block is adapted to the notch on the surface of the disc. By setting the disc, when the disc is rotated so that the surface notch corresponds to the locking block, the sealing plate can be pulled down to open the outlet. After the sealing plate is rotated so that the stop and the baffle are against each other, the notch passes through the locking block. When the disc is released, the torsion spring generates elastic force to squeeze the disc to rotate and abut against the locking block, thus completing the fixation.

[0007] Preferably, a torsion spring is fitted on the surface of the rotating rod. The two ends of the torsion spring are fixedly connected to the disc and the rotating rod, respectively. By setting the torsion spring, when the sealing plate is rotated so that the notch of the disc passes through the locking block, the disc is released. The unrestrained torsion spring generates elastic force to squeeze the disc to rotate, so that it abuts against the locking block, thereby completing the fixation of the position of the disc and the sealing plate, ensuring the stable state after the sealing plate is opened, and reducing the difficulty of opening when there is an object pressing on the sealing plate.

[0008] Preferably, the surface of the baffle is provided with a dust removal component, which includes a hollow tube fixedly connected to the baffle. One end of the hollow tube is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the hollow tube passes through the baffle and is fixedly connected to an airbag. One end of the hollow tube has an air hole. By setting the dust removal component, the airbag is squeezed before the sealing plate is opened, and the air hole cooperates with the connecting pipe to drive the airflow to be discharged along the exhaust pipe to blow away the dust accumulated above the sealing plate, thereby achieving the purpose of dust removal and reducing the occurrence of dust falling when the sealing plate is opened.

[0009] Preferably, the surface of the hollow tube is fitted with an installation ring, which is fixedly connected to the baffle. By setting the baffle, it cooperates with the sealing plate to form a sealing structure, preventing dust and debris from entering the internal space from the gaps in the well wall, thus ensuring a clean and safe working environment inside the well.

[0010] Preferably, there are two mounting rings, which are arranged symmetrically.

[0011] Preferably, an exhaust pipe is fixedly connected to the surface of the hollow tube. The exhaust pipe is connected to the hollow tube, and there are multiple exhaust pipes arranged in a linear array along the hollow tube. By setting the exhaust pipes, when the airbag is squeezed, the airflow is guided above the sealing plate through the air hole and the connecting pipe, blowing away the accumulated dust and reducing the amount of dust falling when the sealing plate is opened.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a separation device, the baffle and sealing plate seal the well wall during use, making it difficult for dust and debris to enter. When the operator needs to exit through the well wall, he rotates the disc. When the notch on the disc surface aligns with the locking block, he pulls down the sealing plate, which rotates and opens the outlet, allowing him to climb out. When the sealing plate is rotated and the baffle and the block abut against it, the notch passes through the locking block, releasing the disc. The torsion spring loses its restraint and generates elastic force to compress the disc, causing it to rotate and abut against the locking block to complete the fixation. The sealing plate rotates inward to open, reducing the difficulty of opening when there is an object pressing down on it. By setting a separation device, dust and debris can be prevented from entering. The operator can enter and exit through the outlet by rotating the disc and pulling down the sealing plate. The inward rotation of the sealing plate reduces the difficulty of opening when there is an object pressing down on it, achieving the effects of sealing and dust prevention, facilitating personnel entry and exit, and flexible opening.

[0013] 2. In this utility model, by setting a dust removal component, the airbag is squeezed before the sealing plate is opened. The airbag, through the air hole and the connecting pipe, drives the airflow to be discharged along the exhaust pipe. When the airflow is discharged, it blows away the dust accumulated above the sealing plate, reducing the situation of dust falling when the sealing plate is opened. By setting a dust removal component, the airbag is squeezed before the sealing plate is opened, and the airbag, through the air hole and the connecting pipe, drives the airflow to be discharged along the exhaust pipe to blow away the dust accumulated above the sealing plate, thus achieving the purpose of dust removal and reducing the situation of dust falling when the sealing plate is opened.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a tail rope isolation device between ladders at the bottom of a main shaft, including a shaft wall 1, a guardrail 2 and a separation device 3. The guardrail 2 is fixedly installed in the inner wall of the shaft wall 1, and the separation device 3 is set on the upper surface of the shaft wall 1.

[0017] In this embodiment: the separation device 3 includes a baffle 31, which is fixedly connected to the upper surface of the well wall 1. An outlet is opened on the surface of the baffle 31. A round rod 33 is rotatably connected to the outlet on the surface of the baffle 31. A sealing plate 32 is fixedly connected to the surface of the round rod 33. A stop block 37 is fixedly connected to the lower surface of the sealing plate 32. The stop block 37 abuts against the baffle 31. A locking block 35 is fixedly connected to the lower surface of the baffle 31. A locking groove is opened on the surface of the locking block 35. A rotating rod 38 is fixedly connected to the lower surface of the sealing plate 32. A disc 36 is rotatably connected to the surface of the rotating rod 38. The disc 36 engages with the locking groove on the surface of the locking block 35. By setting the separation device 3, dust and debris can be prevented from entering. The operator can enter and exit through the outlet by rotating the disc 36 and pulling down the sealing plate 32. The sealing plate 32 can be rotated inward to open, which can reduce the difficulty of opening when there is an object pressing down on it. This achieves the effects of sealing and dust prevention, facilitating personnel entry and exit, and flexible opening.

[0018] Specifically, there are two stops 37, which are symmetrically arranged. The surface of the disc 36 has a notch. The locking block 35 is adapted to the notch on the surface of the disc 36. By setting the disc 36, when the disc 36 is rotated so that the surface notch corresponds to the locking block 35, the sealing plate 32 can be pulled down to open the outlet. After the sealing plate 32 is rotated so that the stops 37 and the baffle 31 abut, the notch passes through the locking block 35. When the disc 36 is released, the torsion spring 39 generates elastic force to squeeze the disc 36 to rotate and abut against the locking block 35, thus completing the fixation.

[0019] Specifically, a torsion spring 39 is fitted onto the surface of the rotating rod 38. The two ends of the torsion spring 39 are fixedly connected to the disc 36 and the rotating rod 38, respectively. By setting the torsion spring 39, when the sealing plate 32 is rotated so that the notch of the disc 36 passes through the locking block 35, the disc 36 is released. The torsion spring 39, which is no longer restrained, generates elastic force to squeeze the disc 36 to rotate, so that it abuts against the locking block 35. This completes the fixation of the position of the disc 36 and the sealing plate 32, ensuring the stable state of the sealing plate 32 after it is opened, and reducing the difficulty of opening when there is an object pressing on the top of the sealing plate 32.

[0020] Specifically, a dust removal component 34 is provided on the surface of the baffle 31. The dust removal component 34 includes a hollow tube 341, which is fixedly connected to the baffle 31. A connecting pipe 345 is fixedly connected to one end of the hollow tube 341. The end of the connecting pipe 345 away from the hollow tube 341 passes through the baffle 31 and is fixedly connected to an airbag 346. An air hole 343 is opened at one end of the hollow tube 341. By setting the dust removal component 34, the airbag 346 is squeezed before the sealing plate 32 is opened. The air hole 343 and the connecting pipe 345 cooperate to drive the airflow to be discharged along the exhaust pipe 344 to blow away the dust accumulated above the sealing plate 32, thereby achieving the purpose of removing dust and reducing the situation of dust falling when the sealing plate 32 is opened.

[0021] Specifically, a mounting ring 342 is fitted onto the surface of the hollow tube 341, and the mounting ring 342 is fixedly connected to the baffle 31.

[0022] In this embodiment: by setting baffle 31, which cooperates with sealing plate 32 to form a sealing structure, dust and debris are prevented from entering the internal space from the gap in well wall 1, ensuring a clean and safe working environment inside the well.

[0023] Specifically, there are two mounting rings 342, which are arranged symmetrically.

[0024] Specifically, an exhaust pipe 344 is fixedly connected to the surface of the hollow tube 341. The exhaust pipe 344 is connected to the hollow tube 341. There are multiple exhaust pipes 344, and the multiple exhaust pipes 344 are arranged in a linear array along the hollow tube 341.

[0025] In this embodiment: by setting an exhaust pipe 344, when the airbag 346 is squeezed, the airflow is directed above the sealing plate 32 through the air hole 343 and the connecting pipe 345, blowing away the accumulated dust and reducing the amount of dust falling when the sealing plate 32 is opened.

[0026] Working principle: By setting up the separation device 3, during use, the baffle 31 and the sealing plate 32 seal the well wall 1, making it difficult for dust and debris to enter. When the operator needs to exit from the well wall 1, the disc 36 is rotated. When the notch on the surface of the disc 36 aligns with the locking block 35, the sealing plate 32 is pulled down, and the sealing plate 32 rotates and opens the outlet, allowing the operator to climb out. When the sealing plate 32 is rotated, the baffle 37 abuts against the baffle 31. At this time, the notch passes through the locking block 35, releasing the disc 36, and the torsion spring 39 loses its restraint. The elastic force generated by the binding compresses the rotating disc 36 and abuts against the locking block 35 to complete the fixation, while the sealing plate 32 rotates inward to open, reducing the difficulty of opening when there is an object pressing on the sealing plate 32. By setting the separation device 3, dust and debris can be prevented from entering. The operator can enter and exit through the outlet by rotating the disc 36 and pulling down the sealing plate 32. The inward rotation of the sealing plate 32 can reduce the difficulty of opening when there is an object pressing on it, thus achieving the effects of sealing and dust prevention, facilitating personnel entry and exit, and flexible opening. By setting up the dust removal component 34, the airbag 346 is squeezed before the sealing plate 32 is opened. The airbag 346, through the air hole 343 and the connecting pipe 345, drives the airflow to be discharged along the exhaust pipe 344. When the airflow is discharged, it blows away the dust accumulated above the sealing plate 32, reducing the amount of dust falling when the sealing plate 32 is opened.
