Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1 As shown, the track cooling pusher provided in this embodiment includes:

[0026] The ice storage box 1 has open ends at both the top and bottom, and an internal cavity for holding ice. The upper open end of the ice storage box 1 is used to add ice, and the lower open end is used for the bottom surface of the ice to contact the top of the rail. In this embodiment, the ice storage box 1 has a rectangular structure.

[0027] The traveling wheel 2 is installed at both the front and rear ends of the ice storage box 1, and can cover the top of the rail to travel on the track. Specifically, the outer diameter of the middle part of the traveling wheel 2 is smaller than the outer diameter of its two ends, so that the two ends can abut against the edge of the rail top to prevent derailment.

[0028] Handrail 3 is connected to ice storage box 1 at one end and extends above ice storage box 1 at the other end. By pushing handrail 3 forward, ice storage box 1 can be moved along the track. In actual use, the worker can hold the top of handrail 3 and push handrail 3 forward to push ice storage box 1 along the track, so that the ice blocks move along the track and cool the track.

[0029] like Figures 2 to 6 As shown in Embodiment 2, water guide plates 4 are provided at the bottom of both sides of the ice storage box 1, and the inner ends of the water guide plates 4 can extend to below the top of the rail. By providing water guide plates 4, the ice water dripping from both sides of the top of the rail after the ice melts can be collected. The ice water flows along the water guide plates 4 and eventually flows onto the rail web. This prevents the waste of ice water and improves the cooling efficiency of the rail.

[0030] In this embodiment, a rotating shaft 5 is provided at the top of the water guide plate 4. The rotating shaft 5 is rotatably mounted on the side of the ice storage box 1. The handrail 3 is rotatably mounted on the side of the ice storage box 1, and a linkage structure is provided at the bottom of the handrail 3. The linkage structure is configured such that when the handrail 3 swings forward, the water guide plate 4 extends from the outside of the rail top into the bottom of the rail top. With this configuration, the handrail 3 can be used to control the opening and closing of the water guide plate 4. When the water guide plate 4 is opened, the distance between two adjacent water guide plates 4 is greater than the width of the rail top, so as to facilitate the movement of the ice storage box 1 up and down the rail. When a pushing force is applied to the handrail 3 to push the ice storage box 1 forward, the pushing force will first cause the handrail 3 to rotate on the ice storage box 1, causing the water guide plate 4 to close, so that the inner end of the water guide plate 4 extends to below the rail top.

[0031] In a relatively specific embodiment, the linkage structure includes a rod sleeve 6, a spiral groove 7, and a slider 8. The rod sleeve 6 is slidably sleeved on the outside of the rotating shaft 5, the spiral groove 7 is opened on the surface of the rotating shaft 5, the slider 8 is slidably engaged with the spiral groove 7, and the slider 8 is fixed on the inner wall surface of the rod sleeve 6. When the top of the handrail 3 rotates forward, its bottom end can press the rod sleeve 6 backward.

[0032] When the handrail 3 is pushed forward, the handrail 3 first rotates on the ice storage box 1. At this time, the bottom end of the handrail 3 will push the rod sleeve 6 backward, causing the rod sleeve 6 to move backward outside the rotating shaft 5. The rod sleeve 6 drives the slider 8 to move backward in the spiral groove 7. Then, the slider 8 drives the rotating shaft 5 to rotate through the spiral groove 7. The rotating shaft 5 then drives the water guide plate 4 to switch from the open state to the closed state.

[0033] Furthermore, a sleeve plate 9 with an open opening facing downwards is fixedly provided at the top of the sleeve 6. A groove 10 is provided at the top of the sleeve plate 9. The bottom end of the handrail 3 passes through the groove 10 and enters the inner cavity of the sleeve plate 9. The width of the groove 10 is adapted to the width of the bottom end of the handrail 3.

[0034] When the handrail 3 rotates, it pushes the sleeve plate 9 to move, causing the rod sleeve 6 to move, thereby controlling the opening and closing of the water guide plate 4. The groove 10 and the bottom of the handrail 3 are designed to stabilize the sleeve plate 9 through the groove 10, preventing the rod sleeve 6 from rotating outside the rotating shaft 5.

[0035] In a relatively specific embodiment, the handrail 3 includes a horizontal bar 3.1, an upper inclined bar 3.2 fixedly disposed on both sides of the bottom of the horizontal bar 3.1, a lower inclined bar 3.3 rotatably connected to the bottom of the upper inclined bar 3.2, a vertical bar 3.4 fixedly disposed on the bottom of the lower inclined bar 3.3 and used to push the rod sleeve 6, and a limiting bar 3.5 fixedly disposed on the bottom of both sides of the upper inclined bar 3.2. The upper inclined bar 3.2 is inclined forward at the bottom, and the lower inclined bar 3.3 is inclined forward at the top. The limiting bar 3.5 located on the rear side of the upper inclined bar 3.2 abuts against the upper surface of the lower inclined bar 3.3. When the upper inclined bar 3.2 rotates forward relative to the lower inclined bar 3.3 until the top is inclined forward to the position of the horizontal bar 3.1 in front of the ice storage box 1, the limiting bar 3.5 located on the front side of the upper inclined bar 3.2 abuts against the lower surface of the lower inclined bar 3.3.

[0036] In this embodiment, when the ice storage box 1 is pushed to move on the top of the rail, the upper inclined rod 3.2 is tilted backward at the top. At this time, the horizontal rod 3.1 is located above the ice storage box 1, while the lower inclined rod 3.3 is tilted forward at the top. The limiting rod 3.5 located behind the upper inclined rod 3.2 is supported on the upper surface of the lower inclined rod 3.3, so that the upper inclined rod 3.2 is stably supported by the lower inclined rod 3.3. In addition, the rear side of the vertical rod 3.4 abuts against the rear inner wall of the groove 10, so that the vertical rod 3.4 can stabilize the rod sleeve 6 and keep the water guide plate 4 in a closed state.

[0037] When placing ice into the ice storage box 1, first rotate the upper inclined rod 3.2 forward until the limiting rod 3.5, located in front of the upper inclined rod 3.2, is supported on the lower surface of the lower inclined rod 3.3. At this time, the crossbar 3.1 is located in front of the ice storage box 1, so that the upper opening of the ice storage box 1 is fully exposed, and the upper inclined rod 3.2 is supported by the lower inclined rod 3.3. At this time, the eccentric force of the upper inclined rod 3.2 and the lower inclined rod 3.3 as a whole is applied to the rod sleeve 6 through the longitudinal rod 3.4, so that the longitudinal rod 3.4 can stabilize the rod sleeve 6 and keep the water guide plate 4 in a closed state. In this state, the water guide plate 4, together with the traveling wheel 2, can stabilize the ice storage box 1 on the track and prevent the ice storage box 1 from tipping over and derailing.

[0038] Furthermore, rollers 11 are provided at both the front and rear ends of the lower surface of the water guide plate 4, and the rollers 11 can roll on the side of the rail web. When pushing the ice storage box 1 along the top of the rail to cool the rail, the rollers 11 roll on the rail web continuously. When passing through the curved area of ​​the rail, the rollers 11 are squeezed by the rail and push the water guide plate 4 outward. The water guide plate 4 then applies a reverse force to the handrail 3 through the linkage structure. At this time, the worker only needs to slightly loosen the handrail 3. After the handrail 3 adapts to the distance the rollers 11 are pushed outward by the rail, the handrail 3 and the water guide plate 4 can regain balance.

[0039] In practical use, the force applied to the guide plate 4 through the linkage structure can control the force of the roller 11 clamping the rail web, which not only prevents derailment, but also allows the roller 11 to adaptively adjust the degree of closure of the guide plate 4 according to the curvature of the track by rolling on the rail web. This, combined with the thrust applied to the handrail 3 during pushing, achieves a new balance.

[0040] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
