Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for coal mine machinery, and in particular to a base for a pulley block of a portable belt conveyor. Background Technology

[0002] In underground coal mining operations, belt conveyors are key equipment for the continuous transport of coal. The reliable fixing of their pulley blocks is crucial to ensuring the stable operation of the transport system. Currently, when installing belt conveyor pulley blocks in underground panel areas, the common method is to fix them by pouring concrete bases on site.

[0003] The construction process requires a large amount of building materials such as concrete, resulting in high material and labor costs. Furthermore, the on-site concrete foundation takes a long time to solidify, which severely restricts the installation and commissioning progress of the belt conveyor and affects the preparation cycle of the entire work area. The concrete foundation is a disposable structure, and when the work area advances or the equipment needs to be moved, the original foundation is abandoned and cannot be reused. This not only wastes resources but also creates additional construction waste disposal problems.

[0004] Therefore, to address the aforementioned issues, a portable base for the pulley block of a belt conveyor can be designed. This base is constructed using a steel structure and can be quickly fabricated using readily available underground steel. It enables efficient and rapid installation and convenient dismantling of the belt conveyor. The steel structure material provides reusability, significantly reducing material costs, effectively improving operational efficiency, and reducing the labor intensity of workers. Simultaneously, it avoids the resource waste and construction waste disposal problems associated with traditional concrete bases, demonstrating significant technical and economic advantages and environmental benefits.

[0017] Example 1 The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 This utility model provides an embodiment: a base for a portable conveyor belt pulley block, including two sets of support frames 1, and a horizontal support part disposed between the two sets of support frames 1. The upper end of the horizontal support part is provided with a mounting bracket 3. A diagonal brace 4 for improving structural strength is welded between the horizontal support part and the support frame 1. The surfaces of the support frame 1, the diagonal brace 4, the horizontal support part and the mounting bracket 3 are all provided with a hot-dip galvanized anti-rust layer to ensure the stability of underground operations. The horizontal support part is a set of long crossbeam plates 201, the two ends of which are welded to the two sets of support frames 1 respectively. The mounting bracket 3 is fixedly connected to the upper end of the long crossbeam plate 201 by welding.

[0019] The support structure consisting of the support frame 1 and the long crossbeam plate 201 is used to support and install the mounting bracket 3. The belt conveyor pulley block can be installed by setting the mounting bracket 3. The whole is made of common underground steel and can realize the efficient and fast installation and convenient dismantling of the belt conveyor. The steel structure material gives it reusability, which greatly saves material costs, effectively improves work efficiency, and reduces the labor intensity of employees.

[0020] Please see Figure 2 In this embodiment, each set of support frames 1 is slidably connected to a set of adjusting columns 5. The side wall of the adjusting column 5 is provided with multiple sets of linearly arranged reserved holes 501, and a fixing pin 502 is inserted inside one set of reserved holes 501. The adjusting column 5 is threadedly connected to two sets of threaded legs 6, and the surface of the threaded legs 6 is provided with several anchor holes 601.

[0021] The adjusting column 5 slides within the support frame 1. After the sliding adjustment is completed, the fixing pin 502 is used in conjunction with the reserved hole 501 to lock it. The height of the mounting bracket 3 can be adjusted according to the situation to adapt to the installation requirements of the belt conveyor pulley block in different environments. The threaded support leg 6 rotates within the adjusting column 5 to level the horizontal support part. After leveling, the adjusting column 5 can be fixed to the ground inside the well using fasteners in conjunction with the anchor hole 601 to ensure stability.

[0022] Example 2 Please see Figure 3 and Figure 4 This utility model provides another embodiment, which differs from embodiment 1 in that, in this embodiment, the horizontal support part includes two sets of short crossbeam plates 202. One end of each set of short crossbeam plates 202 is welded to a set of support frames 1. The free ends of the two sets of short crossbeam plates 202 are hinged to each other by multiple sets of heavy-duty hinges 7. A magnetic suction plate 8 is fixed on the side of one set of short crossbeam plates 202, and the magnetic suction plate 8 is magnetically locked to the corresponding side of the other short crossbeam plate 202. The upper end of each short crossbeam plate 202 and the surface of the mounting bracket 3 are provided with a number of corresponding mounting holes 9. The mounting bracket 3 is connected and fixed to the short crossbeam plate 202 by fasteners through the mounting holes 9.

[0023] The overall support structure is formed by two sets of separate short crossbeam plates 202. When supporting small belt conveyors that need to be moved frequently, the two sets of support frames 1 and short crossbeam plates 202 can be folded along the heavy-duty hinges 7 when the whole device is moved, reducing the space occupied and facilitating the transfer. When setting up, it is only necessary to rotate and open the two sets of support frames 1 and short crossbeam plates 202, use the magnetic suction plate 8 to temporarily position them, and then use fasteners in conjunction with the mounting holes 9 to fix the mounting bracket 3 to the upper end of the two sets of short crossbeam plates 202 to ensure the stability of the overall support structure and improve portability.

[0024] Through the above steps, the support frame 1 and the horizontal support unit together form the main support structure, which supports and installs the mounting bracket 3. The belt conveyor pulley block can be installed through the mounting bracket 3. The whole structure is made of common underground steel, which can realize the efficient and rapid installation and convenient dismantling of the belt conveyor. The steel structure material gives it reusability, which greatly saves material costs, effectively improves work efficiency, and reduces the labor intensity of workers. This solves the problems of high material consumption and labor costs, long construction period, and material waste caused by the inability to reuse traditional concrete bases for belt conveyor pulley blocks.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
