Description

Technical fields:

[0001] This utility model relates to a safety railing, and more particularly to a lifting safety railing for a coke oven maintenance platform. Background technology:

[0002] A coke oven is a furnace used to refine coke. Metallurgical coal is crushed, screened, soaked, and then fed into the coke oven. In the closed coke oven, volatile substances in the coal are separated by heating and dry distillation to produce coke. The prepared coke is then pushed out of the carbonization chamber of the coke oven by a coke car and sent to a coke quenching car.

[0003] To improve coke production capacity and efficiency, coke ovens are often arranged in a row. During the coke pushing process, coke cars are moved along the side of the coke oven machine to push coke into different ovens. Meanwhile, maintenance platforms are installed on both sides of the coke ovens to facilitate inspection and maintenance. However, because the coke cars on the machine side move back and forth, and the pushing rods on the coke cars need to pass through the maintenance platforms to enter and exit the coke ovens, it is impossible to install fixed safety railings on the maintenance platforms. This poses a significant safety hazard, increasing the risk of workers falling from the platforms. Utility model content:

[0004] In order to solve the above problems, the purpose of this utility model is to provide a lifting safety railing for a coke oven maintenance platform.

[0005] This utility model is implemented by the following technical solution:

[0006] A lifting safety railing for a coke oven maintenance platform includes a track and at least one set of guardrail components; the track is fixed to the coke car, and the track includes a descending track, a horizontal track and a lifting track connected in sequence;

[0007] Each set of guardrail components includes a vertical slide rail fixed to the side wall below the maintenance platform and a railing slidably disposed on the vertical slide rail;

[0008] An upper sliding block and a lower sliding block are slidably arranged from top to bottom in the vertical slide rail, and the upper sliding block and the lower sliding block are connected by a connecting component;

[0009] The axle of the roller that matches the track is fixedly mounted on the lower sliding block;

[0010] The top of the vertically installed middle post is fixedly connected to the railing, and the bottom of the middle post is fixedly connected to the upper sliding block.

[0011] Furthermore, the length of the horizontal track is not less than the length of the coke car.

[0012] Furthermore, both the descent track and the lifting track have open ends.

[0013] Furthermore, the connecting assembly includes a connecting rod, the two ends of which are fixedly connected to the upper sliding block and the lower sliding block, respectively.

[0014] Furthermore, the connecting assembly also includes a self-locking assembly, which includes a hinge frame and a tension spring. The hinge frame includes four sequentially hinged connecting rods and is an axisymmetric structure about the vertical direction. One end of the tension spring is connected to the hinge point at the top of the hinge frame, and the other end of the tension spring is connected to the hinge point at the bottom of the hinge frame.

[0015] The top end of the connecting rod is fixedly connected to the upper sliding block, the bottom end of the connecting rod is connected to the hinge point at the top end of the hinge frame, and the hinge point at the bottom end of the hinge frame is connected to the lower sliding block.

[0016] Furthermore, two limiting grooves are symmetrically provided on the two opposite inner walls of the vertical slide; the longitudinal section of the limiting groove is an isosceles triangle, and the base of the isosceles triangle is parallel to the length direction of the vertical slide; the two hinge points in the middle of the hinge frame are respectively slidably disposed in the two limiting grooves.

[0017] Advantages of this utility model:

[0018] When the coke car moves, the guardrail automatically descends along the track to avoid interference with the coke pusher rods on the coke car. When the coke car stops moving and the coke oven needs maintenance, the guardrail remains in a lowered state. As the coke car completes its coke pushing or maintenance work and gradually moves away from the maintenance platform, the guardrail automatically rises along the lifting track, providing safe and reliable protection for maintenance workers. Furthermore, the self-locking component design allows the guardrail to automatically lock after reaching its designated position, preventing it from sliding down in unexpected situations and further enhancing safety.

[0019] This utility model features an ingenious and compact design, and is easy to operate, providing a high-efficiency, safe, and reliable lifting safety railing for coke oven maintenance platforms. Attached image description:

[0028] Example 1:

[0029] like Figure 1-5 The illustrated coke oven maintenance platform lifting safety railing includes a track and at least one set of guardrail components 3; the track is fixed on the coke car 4, and the track includes a descending track 21, a horizontal track 22 and a lifting track 23 connected in sequence; wherein, the length of the horizontal track 22 is 2 meters longer than the length of the coke car 4, and the free ends of the descending track 21 and the lifting track 23 are both open structures.

[0030] Each set of guardrail components 3 includes a vertical slide rail 31 fixed to the side wall below the maintenance platform 1 and a railing 32 slidably mounted on the vertical slide rail 31;

[0031] An upper sliding block 33 and a lower sliding block 34 are slidably arranged from top to bottom in the vertical slide rail 31. The upper sliding block 33 and the lower sliding block 34 are connected by a connecting assembly 35. The axle of the roller 36 that matches the track is fixedly installed on the lower sliding block 34. The top of the vertically arranged middle upright 37 is fixedly connected to the middle of the railing 32, and the bottom of the middle upright 37 is fixedly connected to the upper sliding block 33.

[0032] In this embodiment, the connecting component 35 includes a connecting rod 351, with both ends of the connecting rod 351 fixedly connected to the upper sliding block 33 and the lower sliding block 34, respectively; it also includes a self-locking component, which includes a hinge frame 352 and a tension spring 353. The hinge frame 352 includes four sequentially hinged connecting rods and is an axisymmetric structure about the vertical direction; one end of the tension spring 353 is connected to the hinge point at the top of the hinge frame 352, and the other end of the tension spring 353 is connected to the hinge point at the bottom of the hinge frame 352; the top of the connecting rod 351 is fixedly connected to the upper sliding block 33, the bottom of the connecting rod 351 is connected to the hinge point at the top of the hinge frame 352, and the hinge point at the bottom of the hinge frame 352 is connected to the lower sliding block 34. Two symmetrical limiting grooves 354 are provided on two opposite inner walls of the vertical slide rail 31, and the two limiting grooves 354 are respectively provided on opposite outer sides of the vertical slide rail 31; the longitudinal section of the limiting groove 354 is an isosceles triangle, and the base of the isosceles triangle is parallel to the length direction of the vertical slide rail 31; the two hinge points in the middle of the hinge frame 352 are respectively slidably disposed in the two limiting grooves 354. In this embodiment, since the wall thickness of the vertical slide rail 31 is small, the limiting grooves 354 are provided on the outside of the vertical slide rail 31.

[0033] Instructions for use:

[0034] When using this embodiment as a safety railing for the coke-side maintenance platform 1, firstly, a track is fixed on the side of the coke car 4 closest to the maintenance platform 1, and the front and rear ends of the horizontal track 22 are aligned with the center of the front and rear ends of the coke car 4, so that the descending track 21 is located in front of the coke car 4 and the lifting track 23 is located behind the coke car 4. Since the self-locking component can limit the movement of the railing component 3 when the coke car 4 is not close to the maintenance platform 1, that is, when the track on the coke car 4 does not interact with the railing assembly 3, the railing assembly 3 is in a raised state, thus protecting the maintenance platform 1; therefore, when installing the track, the height of the free end of the descending track 21 should match the height of the roller 36 of the railing assembly 3 in the raised state. To facilitate the entry of the roller 36 into the descending track 21, the free end of the descending track 21 is set as an open structure.

[0035] As the coke car 4 moves forward and approaches the maintenance platform 1, the roller 36 first enters the descending track 21. As the coke car 4 continues to move forward, limited by the height of the descending track 21, the roller 36 can only drive the lower sliding block 34 to move downwards along the descending track 21 within the vertical slide rail 31, thereby driving the upper sliding block 33 to also move downwards. The downward movement of the upper sliding block 33 will drive the intermediate upright 37 downwards, thus causing the guardrail 32 to move downwards. In this embodiment, by adjusting the length or tilt angle of the descending track 21, the guardrail 32 can be positioned at a height that does not obstruct the movement of the coke car 4 when the roller 36 reaches the end of the descending track 21; thus, the normal coke pushing or blocking operation of the coke car 4 can be guaranteed.

[0036] Afterwards, the coke car 4 continues to move forward and arrives near the maintenance platform 1, where it begins the coke pushing operation. During this process, since the roller 36 is within the horizontal track 22, that is, at the same height as the end of the descending track 21, the guardrail 32 is always in a descending state when the roller 36 is within the horizontal track 22, ensuring the normal operation of the coke car 4.

[0037] As the coke car 4 continues to move forward, when the roller 36 moves into the lifting track 23, the roller 36 moves upward continuously, which is the opposite of the movement of the roller 36 when it is in the lowering track 21. This causes the lower sliding block 34 to move upward continuously as well. The upward movement of the lower sliding block 34 further causes the upper sliding block 33 to move upward. Under the action of the middle upright 37, the railing 32 is then rotated upward, eventually reaching the raised state, which achieves the effect of protecting the safety of workers.

[0038] In this embodiment, when the coke car 4 moves away from the maintenance platform 1, the two hinge points in the middle of the hinge frame 352 are restricted within the two limiting grooves 354 by the self-locking component, preventing movement and forming a self-lock. This provides limiting protection for the upper sliding block 33 and the lower sliding block 34, preventing them from moving up or down and ensuring the safety railing does not descend. Only when the track forcibly applies external force to the roller 36 will the two hinge points in the middle of the hinge frame 352 be forcibly displaced, causing the railing 32 to descend.

[0039] In this embodiment, by setting tracks at different angles, and with the track limiting rollers 36, the safety railing can be raised and lowered without any power drive when the coke car 4 moves. When the coke car 4 needs to approach the maintenance platform 1 on both sides of the coke oven for work, the safety railing will automatically lower to ensure the normal operation of the coke car 4; when the coke car 4 leaves, the safety railing will automatically rise, which can protect the safety of the workers and greatly reduce the risk of falling. The entire structure adopts a pure mechanical drive principle, without the need for a power drive mechanism, and has high reliability, thus improving the protective effect.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. The lifting safety railing in this embodiment can serve as either a safety railing on the coke side or a safety railing on the machine side; the coke car in this embodiment can be either a coke pusher car or a coke catcher car. Any modifications, equivalent substitutions, or improvements made to the guardrail assembly 3 and the track 2, as long as their structure and working principle are within the spirit and principles of this utility model, should be included within the protection scope of this utility model.
