DETAILED DESCRIPTION
[0017] The annular channel emergency passage device of the utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0018] like Figure 1 As shown, the annular channel emergency passage device of the utility model equipment includes an arc track 2, and two locking devices 3 are fixed on the surface of the arc track 2. The two locking devices 3 are arranged at both ends of the arc track 2. A sliding pedal 4 is provided on the arc track 2, and the sliding pedal 4 is located between the two locking devices 3. During use, the sliding pedal 4 is fixed on the hollow 8 to allow personnel to pass through the hollow 8 smoothly. The sliding pedal 4 includes a horizontal plate 10, and hand push rods 9 are welded at two diagonals on the surface of the horizontal plate 10. Both sides of the horizontal plate 10 are fixedly connected to inclined plates 11, and hook blocks 6 are respectively welded on the two inclined plates 11. Sliding rollers 5 are respectively provided at the four corners of the bottom of the horizontal plate 10, and the sliding rollers 5 are matched with the arc track 2 away from the side of the horizontal plate 10.
[0019] The locking devices 3 are respectively located on both sides of the arc track 2. The locking devices 3 include a support ear 301, which is welded on the arc track 2. A movable rotating shaft 302 is provided on the inner side of the support ear 301. A torsion spring 305 is fixed to the side of the support ear 301 close to the sliding pedal 4. The other end of the torsion spring 305 is connected to a locking hook 303, so that the hook 303 forms a downward torque for a long time. A foot pedal 304 is provided on the side of the support ear 301 away from the locking hook 303. The sliding pedal 4 can be fixed by setting two locking devices 3. During use, the sliding pedal 4 can be kept fixed to avoid the risk of the operator falling due to the sliding of the sliding pedal 4, and also avoid the risk of being unable to pass normally. The safety factor of the inspection and operating personnel can be improved and the safety risk can be reduced.
[0020] The inclined plate 11 and the horizontal plate 10 are inclined at an angle of 135° toward one side of the arc track 2. The hook block 6 is a parallelogram. The hook block 6 is close to the locking device 3 and is provided with an inclined surface that matches the locking hook 303. When the sliding pedal 4 approaches the locking device 3, the top of the locking hook 303 fits exactly with the inclined surface of the hook block 6. When the sliding pedal 4 continues to approach the locking device 3, the locking hook 303 is supported by the inclined surface of the hook block and lifted upward until it passes the top corner of the parallelogram of the hook block 6. The locking hook 303 is quickly rebounded by the torsion spring 305 and hooked with the vertical surface of the hook block 6. At this time, the top of the sliding pedal 4 collides with the locking device support ear 3-1 and stops sliding. The hook block 6 can clamp the locking hook 303 to keep the sliding pedal stable.
[0021] The arc track 2 is paved with round steel, the sliding roller 5 cooperates with the arc track 2, and the installation angle of the sliding roller 5 is equal to the outer setting angle of the arc track 2, which can reduce the resistance of the sliding pedal 4 when sliding.
[0022] The push rod 9 is perpendicular to the horizontal plate 10 , and the push rod 9 can be used to push the sliding pedal 4 to the other end of the arc track 2 .
[0023] The length of the sliding pedal 4 is greater than the length of the cavity 8 opened at the staircase 7 of the annular passage 1 , the effective stroke of the arc track 2 is twice the length of the sliding pedal 4 , and the width of the sliding pedal 4 is not less than the width of the arc track 2 .
[0024] The specific working process of the utility model equipment annular channel emergency passage device is as follows:
[0025] like Figure 2As shown, the equipment annular channel emergency passage device is installed on the side where the staircase 7 cannot be directly passed and a detour is required. When personnel are inspecting or working in the annular channel 1, once the location is more than two-thirds of the way along the annular channel 1 from the stair entrance or the return path is inaccessible due to other risks, the operator can quickly go to the equipment annular channel emergency passage device, step on the foot pedal 304 of the locking device 3 with one foot, step on the inclined plate of the sliding pedal 4 with the other foot or use the push rod 9 to push forward violently. At this time, the sliding pedal 4 will slide forward along the curved track 2 and gradually cover the hollow 8 at the stair entrance until the hook block 6 on the other side of the sliding pedal 4 is hooked by the locking hook 303 of the locking device 3 on the diagonal side of the curved track 2. At this time, the personnel quickly cross the stair entrance through the sliding pedal 4, step on the foot pedal 304 of the locking device 3 on the other side, push the sliding pedal 4 back, vacate the stair entrance blocked by the sliding pedal 4, and leave the dangerous area along the stairs 7 under the hollow 8.
