Description

Technical Field

[0001] This utility model belongs to the field of calcium carbide transportation technology, specifically relating to a side-tipping unloading device. Background Technology

[0002] The production process using calcium carbide as raw material inevitably consumes a large amount of calcium carbide, which is generally purchased externally. Therefore, it is mainly transported to the factory by truck from other locations.

Conventional calcium carbide trucks often require manual assistance to open the doors during tipping and unloading on the platform. Limiting and positioning devices cannot accurately position the trucks, preventing bidirectional unloading. Furthermore, fine particles adhering to the calcium carbide truck cannot be unloaded, resulting in incomplete unloading. Therefore, a side-tipping unloading device that enables bidirectional and clean unloading is needed. Utility Model Content

[0038] like Figures 1 to 5 As shown, this utility model includes a tilting unloading platform 1, a tilting cylinder 2 for tilting the unloading platform 1, and a wheel clamping assembly installed on the unloading platform 1. A car stop door device is provided on one side of the unloading platform 1. Wheel limiting mechanisms 5 for limiting the calcium carbide car 28 are respectively provided at both ends of the unloading platform 1. A material receiving mechanism is provided on one side of the unloading platform 1, and a vibrator 17 is provided on the other side of the unloading platform 1.

[0039] A wheel clamping assembly is provided at each end of the unloading platform 1. The wheel clamping assembly includes a first clamping plate 6 and a second clamping plate 9 respectively provided on both sides of the unloading platform 1 for clamping the wheels of the carbide car 28. A first pushing cylinder 7 for driving the first clamping plate 6 to move and a second pushing cylinder 10 for driving the second clamping plate 9 to move are provided inside the unloading platform 1.

[0040] The receiving mechanism includes a fixed receiving frame 14 and a follower receiving frame 15 that is slidably installed on the upper part of one side of the fixed receiving frame 14. The follower receiving frame 15 is connected to the first clamping plate 6.

[0041] A vibrator bracket 16 is hinged to the unloading platform 1 near the second clamping plate 9. The vibrator 17 is mounted on the vibrator bracket 16. The unloading platform 1 is also equipped with a tilting cylinder 18 for driving the vibrator bracket 16 to rotate.

[0042] In actual use, by setting wheel clamping components and wheel limiting mechanisms 5 at both ends of the unloading platform 1, the calcium carbide car can be accurately limited and positioned. At the same time, it can realize bidirectional vehicle unloading, which is convenient to operate, can effectively improve the unloading efficiency of calcium carbide car, and has a wide range of applicability.

[0043] It should be noted that by combining the fixed receiving frame 14 and the follower receiving frame 15 to form a receiving mechanism, not only can the material be better received onto the receiving plate, but it can also work with the first clamping plate 6 to prevent the vehicle from sliding sideways.

[0044] In addition, by installing a vibrator 17 on the unloading platform 1 through the vibrator bracket 16, the vibrator 17 can be activated to generate mechanical vibration in the calcium carbide car during unloading, thereby enabling the fine materials in the calcium carbide car to fall evenly and unload more cleanly.

[0045] In practice, the cylinder body of the tilting cylinder 18 is hinged to the unloading platform 1, and the plunger end of the tilting cylinder 18 is hinged to the upper end of the vibrator bracket 16.

[0046] like Figure 1 and Figure 2 As shown in this embodiment, the upper part of the unloading platform 1 is provided with a support frame 19, and the blocking door device includes a blocking door arm 20 rotatably installed on the top of the support frame 19 and a blocking door cylinder 23 for driving the blocking door arm 20 to rotate. The cylinder body of the blocking door cylinder 23 is installed on the support frame 19, and the plunger end of the blocking door cylinder 23 is connected to the tail end of the blocking door arm 20.

[0047] In actual use, the support frame 19 is fixed to the support beam fixed on the side of the unloading platform 1.

[0048] It should be noted that multiple car door arms 20 are rotatably installed on the top unloading side of the support frame 19. Each car door arm 20 corresponds to a car door cylinder 23. The lower ends of the multiple car door arms 20 are connected to a pressure rod 21. Multiple rollers 22 are installed on the pressure rod 21 along its length. The rollers 22 can effectively reduce the friction between the car door device and the calcium carbide car. At the same time, the rollers are made of flexible material to avoid rigid collision with the calcium carbide car.

[0049] In specific implementation, the support frame 19 is provided with a hinge seat for the rotating installation of the car door arm 20 and a cylinder hinge seat for the cylinder body of the car door cylinder 23.

[0050] like Figure 2 As shown in this embodiment, a plurality of tilting cylinders 2 are hinged to one side bottom of the unloading platform 1, and the cylinder body of the tilting cylinder 2 is hinged to the cylinder support 3. A plurality of slewing supports 4 for hinged installation of the unloading platform 1 are provided on the other side bottom.

[0051] In actual use, the tilting cylinder 2 on one side of the unloading platform 1 is mounted on the foundation through the cylinder support 3, and the other side of the unloading platform 1 is mounted on the foundation through the slewing support 4. The two sides of the foundation are at different heights, which makes it easy for the unloading platform 1 to be laid flat.

[0052] like Figure 1 and Figure 2 As shown in this embodiment, a flat lifting sling winding device is provided on one side of the unloading platform 1. The flat lifting sling winding device includes a flat lifting sling winding cover 24, a hydraulic winch 25 disposed inside the flat lifting sling winding cover 24, and a flat lifting sling 26 wound on the drum of the hydraulic winch 25. A self-locking hook 27 is provided at the end of the flat lifting sling 26.

[0053] In actual use, the self-locking hook 27 can be locked to one side of the calcium carbide car, which makes it easy to secure the calcium carbide car through the flat lifting strap winding device and prevent the calcium carbide car from slipping during the unloading process.

[0054] like Figure 4 As shown, in this embodiment, the wheel limiting mechanism 5 includes a limiting slider 51 and a lifting cylinder 52 connected to the bottom of the limiting slider 51 and used to drive the limiting slider 51 to rise and fall. The lifting cylinder 52 is installed in the unloading platform 1, and the top surface of the unloading platform 1 is provided with a slot for the limiting slider 51 to slide through.

[0055] In actual use, two limit sliders 51 are arranged side by side at both ends of the unloading platform 1. The two limit sliders 51 arranged side by side are used to limit the wheels on both sides of the carbide ...

[0056] like Figure 2 and Figure 5 As shown, in this embodiment, the fixed receiving frame 14 is fixed on the unloading platform 1, and the outer side of the fixed receiving frame 14 is provided with an inclined surface 141. The follower receiving frame 15 is an L-shaped frame and it is slidably erected on the fixed receiving frame 14 on the side away from the inclined surface 141.

[0057] In actual use, by setting an inclined surface 141 on the outside of the fixed receiving frame 14, when the unloading platform 1 is flipped to the maximum unloading angle of 35°, the inclined surface 141 is just parallel to the receiving plate. During the flipping process of the unloading platform 1, when there is material on the inclined surface 141, it will not generate pressure on the receiving plate.

[0058] It should be noted that when the follower receiving frame 15 moves with the first clamping plate 6 to the furthest distance from the fixed receiving frame 14, the top of the follower receiving frame 15 and the top of the fixed receiving frame 14 are slidably overlapped.

[0059] like Figure 3As shown, in this embodiment, the cylinder body of the first pushing cylinder 7 is connected inside the unloading platform 1, and the plunger end of the first pushing cylinder 7 is connected to a first sliding bracket 8 connected to the first clamping plate 6. The cylinder body of the second pushing cylinder 10 is connected inside the unloading platform 1, and the plunger end of the second pushing cylinder 10 is connected to a second sliding bracket 11 connected to the second clamping plate 9.

[0060] In this embodiment, the first clamping plate 6 and the second clamping plate 9 are respectively disposed on the upper sides of the unloading platform 1. The top surface of the unloading platform 1 is provided with a first sliding groove 12 for the first sliding bracket 8 to slide through, and the top surface of the unloading platform 1 is provided with a second sliding groove 13 for the second sliding bracket 11 to slide through.

[0061] In actual use, when the calcium carbide carbide carbide 28 travels from one end of the unloading platform 1 onto the unloading platform 1, the two lifting cylinders 52 at the other end of the unloading platform 1 lift the two limiting sliders 51 upwards, causing the two limiting sliders 51 to pass through their corresponding slots and rise to the top of the unloading platform 1. When the calcium carbide carbide carbide 28 moves to the other end of the unloading platform 1, the two limiting sliders 51 limit the wheels of the calcium carbide ... The calcium carbide car is secured. By activating the door-blocking cylinder 23, the door-blocking device presses the car door of the calcium carbide car tightly. The unloading platform 1 is rotated at a certain angle by the tilting cylinder 2. Then, the latch at the car door of the calcium carbide car is manually removed. By activating the door-blocking cylinder 23, the door-blocking device is separated from the car door of the calcium carbide car 28. The material loaded in the calcium carbide car 28 is unloaded onto the receiving plate by the receiving device. During the unloading process, the vibrator bracket 16 is rotated by the tilting cylinder 18 until the vibrator 17 is in contact with the outer wall of the car body of the calcium carbide car 28. Then, the vibrator 17 is activated to generate mechanical vibration in the calcium carbide car, which enables the fine material in the calcium carbide car 28 to fall evenly until the unloading of the calcium carbide car 28 is completed.

[0062] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
