Description

Technical Field

[0001] This utility model relates to the technical field of material loosening equipment, specifically to a gantry-type rail transport loosening equipment, which is mainly suitable for crushing and loosening hardened or frozen materials during train transportation to facilitate subsequent unloading operations. Background Technology

[0002] With increasingly stringent environmental protection requirements, more and more raw material companies are choosing to spray dust suppressants on the surface of materials during loading and unloading. The main function of dust suppressants is to form a crust on the surface of the materials, thereby reducing dust and spillage. However, the crust formation can affect automated unloading equipment, as the resulting crust can prevent automatic unloading or increase the difficulty of unloading.

[0003] In addition, extremely cold weather can cause materials to freeze completely, making it impossible to unload them and causing certain difficulties for raw material users. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a gantry-type fire transport loosening device; the loosening device breaks up the hardened or frozen layer to facilitate unloading.

[0005] This utility model adopts the following technical solution: a gantry-type fire transport loosening device, comprising:

[0006] The gantry crane is slidably mounted on the main roadway rails.

[0007] The trolley is slidably mounted on the trolley track; the trolley track is fixed to the top of the gantry crane and is perpendicular to the crane track.

[0008] The lifting assembly is fixedly connected to the trolley.

[0040] Example 1:

[0041] like Figures 1 to 4As shown, this utility model provides a gantry-type fire transport loosening device, in which a gantry trolley 1 is slidably mounted on a main roadway rail 2. A trolley rail 4 is fixed to the top of the gantry trolley 1, perpendicular to the main roadway rail 2, and a trolley 3 is slidably mounted on the trolley rail 4. A lifting assembly 5 is fixed below the trolley 3. A loosening device 6 is fixed to the actuator end of the lifting assembly 5, and the lifting assembly 5 controls the lifting and lowering of the loosening device 6.

[0042] Combination Figure 3 , Figure 4 As shown, the lifting assembly 5 includes a base frame 51, which is fixed under the trolley 3. Inside the base frame 51 are four rectangularly arranged vertical slide rails 511. The slide 55 has a frame structure, and four rectangularly arranged guide wheels 551 are fixed at both the upper and lower ends of the slide 55. The guide wheels 551 are in a one-to-one rolling connection with the slide rails 511, so that the slide 55 can be stably raised and lowered along the slide rails 511.

[0043] A pair of upper sprockets 52 and a pair of lower sprockets 53 are fixed to the upper and lower ends of the base frame 51, respectively. The two upper sprockets 52 are fixed via a drive shaft, and the two lower sprockets 53 are fixed via another drive shaft. A lifting drive motor 57 is fixed to the upper end of the base frame 51 and is fixedly connected to the upper drive shaft. The lifting drive motor 57 can control the forward and reverse rotation of the upper sprockets 52. Two drive chains 54 are correspondingly installed on the upper sprockets 52 and lower sprockets 53. The side of the drive chain 54 closest to the slide 55 is connected to the slide 55, and a shock absorber 56 is provided at the connection between the drive chain 54 and the slide 55. The rotating drive chain 54 can control the lifting and lowering of the slide 55, and the shock absorber 56 can reduce the reaction force of the loosener 6 on the drive chain 54 during operation.

[0044] Combination Figures 1 to 4 As shown, in this embodiment, multiple looseners 6 are provided, and the multiple looseners 6 are arranged in a row along the trolley track 4. The loosener 6 includes a vertical support sleeve 61 fixedly connected to the slide 55, and a rotating shaft 62 is rotatably installed in the support sleeve 61, with both ends of the rotating shaft 62 extending out of the support sleeve 61. A loosening drive motor 63 is connected to the upper end of the support sleeve 61, and the loosening drive motor 63 is fixed on the slide 55; a crushing head 64 is fixed to the lower end of the support sleeve 61.

[0045] Example 2:

[0046] Based on the above embodiment one, combined with Figures 1 to 4As shown, this embodiment provides a gantry crane 1. Two main tracks 2 are arranged parallel to each other on both sides of a railway track 7, and a train carriage 8 is located on the railway track 7. The top ends of two support legs 11 are fixedly connected by two crossbeams 12 and two longitudinal beams, and a trolley track 4 is fixed on each crossbeam 12. The bottom ends of the support legs 11 are fixed with gantry crane wheels 13, which are rolled on the corresponding main track 2. The gantry crane wheels 13 are connected to a gantry crane drive motor 14, which controls the gantry crane 1 to move linearly back and forth along the railway track 7, so that the equipment can move to the position of any train carriage 8.

[0047] Example 3:

[0048] Based on the above-described embodiment two, combined with Figures 1 to 4 As shown, this embodiment provides a trolley 3. The trolley 3 is arranged between two crossbeams 12, and two trolley wheels 32 are fixed to the bottom of each side of the trolley 3. The trolley wheels 32 are rolled on the corresponding trolley tracks 4. The trolley wheels 32 are connected to a trolley drive motor 33, which controls the trolley 3 to move in a straight line reciprocating motion perpendicular to the railway track 7, so that the trolley 3 can travel to the upper position inside the train carriage 8.

[0049] Working principle:

[0050] After the train stops, the operator manually moves the gantry crane 1 along the main track 2 to the front of the first train car 5 via the control panel.

[0051] The operator moves the trolley 3 along the trolley track 4, so that the trolley 3 stops directly above the train carriage 8;

[0052] When the operator starts the lifting assembly 5, the slide 55 in the lifting assembly 5 moves downward, which drives the loosener 6 to move downward; at the same time, the loosener 6 starts, which drives the crushing head 64 below to rotate; during the downward movement, the crushing head 6 contacts the material and continues to rotate and crush it.

[0053] After moving downwards to the set depth, the lifting assembly 5 begins to move upwards, driving the loosener 6 upwards until it returns to the initial height position, and the loosener 6 stops rotating; at this point, the loosening and crushing of a set of points is completed.

[0054] Then, the personnel operated the gantry crane 1 to continue moving, repeating the above process on each train car one by one, until all the train cars 8 within the range of the gantry rail 2 were loosened and broken.

[0055] After completion, the personnel operate the gantry crane 1 back to the starting point, ready to loosen and crush the next set of train carriages 8.

[0056] As can be seen from the above embodiments, this utility model can be used in conjunction with automated unloading equipment such as tippers, screw conveyors, and bottom-discharge carriages, solving the problem that it is difficult to use automated unloading equipment for caking or frozen materials in railway transportation conditions. This utility model can reduce labor intensity, improve unloading efficiency, eliminate the safety hazards of manual material handling, and provide raw material users with a perfect material loosening and crushing solution, saving energy and increasing efficiency.
