[0002] The coke oven is generally over ten meters high, with platforms five or six meters high on both sides, each two or three meters wide and the length of the oven. These are called coke oven side platforms in the industry. Their purpose is for workers to operate the coke oven when adding coal and discharging coke. However, due to the equipment used for the coal feeding car, coke pushing car, and coke quenching car on the coke side, standard railings cannot be installed. This poses a risk of falls from height for workers operating on the coke oven side platforms, a safety hazard present in all coke ovens. Because of process requirements, the coal feeding car, coke pushing car, and coke quenching car on the coke side all move back and forth along the sides of the coke oven, which makes it impossible to install ordinary railings made of iron pipes, creating a significant safety hazard.

[0029] Furthermore, the terms “comprising,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may also include other steps or units that are not expressly listed but are inherent to these processes, methods, products, or devices, or steps or units added based on further optimizations of the inventive concept.
[0030] like Figures 1-6 As shown, this utility model discloses a coke oven safety device, including a coke oven body 1, a coke quenching car 2 installed on one side of the coke oven body 1, the coke quenching car 2 being mounted on a slide rail, and a coke-side platform 3 being provided between the coke quenching car 2 and the coke oven body 1, and further including:
[0031] Fixed support rod 4, two fixed support rods 4 are provided, and the fixed support rods 4 are provided on both sides of the coke side platform 3 along the moving direction of the coke quenching car 2;
[0032] At least one iron chain 5 is provided, and the two ends of the iron chain 5 are respectively fixedly connected to two fixed support rods 4;
[0033] The pulley system 6 consists of four sets, each set including at least one first fixed pulley. The number of first fixed pulleys is the same as the number of chains 5. The four sets of pulley systems 6 are arranged sequentially on the four sides of the coke quenching car 2 along the moving direction of the coke quenching car 2. The chains 5 pass through the first fixed pulley below one side of the coke quenching car 2, then through the two first fixed pulleys at the top of the coke quenching car 2, and finally out through the first fixed pulley below the other side of the coke quenching car 2.
[0034] The coke oven body 1, coke quenching car 2, coke side platform 3, and slide rail mentioned above are all existing technologies and will not be described in detail here;
[0035] The pulley block 6 can be installed not only on the coke quenching car 2, but also on equipment such as the coke pusher car and the coal feeding car.
[0036] The fixed support rod 4 can be made of metal or stone. It is inserted and fixed to the coke side platform 3 or the ground. The fixed support rod 4 is set close to the edge of the coke side platform 3. The two ends of the iron chain 5 are fixedly connected to the fixed support rod 4 at both ends of the coke side platform 3 and are about 1m above the ground. The specific distance depends on the number of iron chains 5. In this embodiment, three iron chains 5 are set. The lowest iron chain 5 is 50cm above the ground and the spacing between each pair is 50cm.
[0037] On the coke quenching car 2, a set of pulleys 6 is installed on each of the four sides in the direction of movement. This allows the chain 5 to pass under the pulley 6 at the bottom of one side of the coke quenching car 2, then over the first pulley 6 at the top, then over the pulley 6 in the front (direction of movement), and finally under the pulley 6 at the bottom of the coke quenching car 2. In other words, the chain 5 passes around three sides (two sides and the top) of the coke quenching car 2. During the movement of the coke quenching car 2, the chain 5 can move along with it due to the action of the pulleys 6, without affecting the coke quenching car 2, and can play a protective role.
[0038] In a further embodiment, each pulley group 6 includes three first fixed pulleys, and a connecting plate 7 is fixedly connected to the side of the coke chock car 2. The three first fixed pulleys are spaced apart on the connecting plate 7, and the connecting plate 7 is set at an acute angle to the horizontal plane.
[0039] The number of the first fixed pulleys in each pulley group 6 is matched with the number of chains 5, and they are installed on the connecting plate 7 and rotate synchronously.
[0040] In another embodiment, since the focal side platform 3 is too long, the iron chain 5 will sag in the middle under the action of gravity. Therefore, a sling mechanism 8 is also included. The sling mechanism 8 includes a sling track 81. The two ends of the sling track 81 are fixedly connected to the top of the fixed support rod 4. A sling rope 82 is provided between the sling track 81 and the iron chain 5. The bottom of the sling rope 82 is fixedly connected to the iron chain 5. The top of the sling rope 82 is connected to the track trolley 83 on the sling track 81. A spherical locking block 84 is provided at the bottom of the sling rope 82 near the upper part of the iron chain 5. The spherical locking block 84 is eccentrically positioned with respect to the connecting plate 7.
[0041] Multiple slings 82 and track trolleys 83 can be installed to lift the chain 5 at multiple locations, preventing the chain 5 from sagging too much and failing to provide protection.
[0042] To prevent interference between the sling rope 82 and the movement of the coke chuck 2, a spherical locking block 84 is provided on the sling rope 82 (see...). Figure 3), and about 15cm away from the iron chain 5 below it (directly opposite the first fixed pulley), and as the coke chuck 2 moves, the pulley block 6 gradually approaches the sling rope 82 and the locking block 84, until the connecting plate 7 of the pulley block 6 first contacts the locking block 84 (participating in the process). Figure 4 Because the connecting plate 7 and the locking block 84 are eccentrically positioned, during the contact process between the locking block 84 and the connecting plate 7, the locking block 84 will be pushed to shift towards the side of the first fixed pulley (see...). Figure 5 After passing the connecting plate 7, the locking block 84 makes eccentric contact with the first fixed pulley. Under the action of the traveling force, the locking block 84 is oriented to one side by the first fixed pulley, and the sling rope 82 above the locking block 84 is shifted to one side of the first fixed pulley. Meanwhile, the sling rope 82 between the locking block 84 and the chain 5 wraps around the bottom of the first fixed pulley (see...). Figure 6 This ensures that the sling rope 82 does not affect the movement of the pulley block 6 on the chain 5.
[0043] The bottom end of the sling rope 82 is connected to three iron chains 5 in sequence, and a spherical locking block 84 is provided above each iron chain 5.
[0044] In a further embodiment, one end of the chain 5 is fixedly connected to one of the fixed support rods 4, and a second fixed pulley 9 is provided on the other fixed support rod 4. The other end of the chain 5 passes through the top of the second fixed pulley 9, and a counterweight 10 is fixedly connected to the end passing through the fixed pulley.
[0045] By making one end of the chain 5 a movable structure, due to thermal expansion and contraction, the chain 5 is prone to sag severely when the temperature is too high. The chain 5 can be appropriately tightened by the counterweight 10.
[0046] The track trolley 83 is equipped with a spring winding mechanism, and the top end of the sling rope 82 is connected to the spring winding mechanism.
[0047] By setting up a winding mechanism, which adopts a spring-type structure, part of the sling rope 82 can be retracted as the sling rope 82 moves with the iron chain 5 to the pulley block 6 above the coke chock car 2, thus avoiding affecting the movement of the pulley block 6.
[0048] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0049] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
[0050] The present invention has been described in detail above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
