Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 3This utility model provides an embodiment: a special tool for a hydraulic support column for working face transportation, including a chain link 1, a fixing rod 2, a bracket 3, and a pin 4. Two sets of fixing rods 2 are provided, each set located on both sides of the chain link 1. The two sets of fixing rods 2 contact the side walls of the chain link 1. Each side wall of the two sets of fixing rods 2 has a through pin hole 201. The pin 4 is located inside the pin hole 201 and is slidably connected to the fixing rod 2. The bracket 3 is fixedly installed above the fixing rod 2, and the pin 4 passes through the chain link 1. By setting... The bracket 3 can support the transported column. The bracket 3 is supported and installed by setting two sets of fixing rods 2. The two sets of fixing rods 2 can clamp the chain link 1 in the middle. The pin 4 can be installed by setting the pin hole 201. The two sets of fixing rods 2 and the chain link 1 can be fixedly installed by setting the pin 4, so that the bracket 3 can be fixed above the chain link 1 of the scraper conveyor. According to the size of the column, multiple sets of special tools can be installed on the chain link 1 of the scraper conveyor, so that the bracket 3 can support and limit the transported column.

[0023] Please see Figure 1 and Figure 2 In this embodiment, the bracket 3 has a semi-circular arc structure, and its diameter is consistent with the cross-sectional diameter of the transported column. A rubber pad 301 is provided on the upper surface of the bracket 3. The semi-circular arc structure of the bracket 3 supports and supports the column, limiting its movement and preventing lateral swaying. The rubber pad 301, in direct contact with the column surface, protects the column surface, preventing wear between it and the bracket 3, and increases friction, making the column supported by the bracket 3 more stable. The pin 4 has a threaded section 401 on its surface, located at one end of the pin 4. A locking nut 402 is provided around the pin 4, and the locking nut 402 is threaded with the pin 4. The locking nut 402 is located on one side of a set of fixing rods 2. The threaded section 401 allows the locking nut 402 to be threadedly connected to the pin 4. The locking nut 402 can lock the pin 4, preventing the pin 4 from accidentally coming out of the pin hole 201 during transportation. The two sets of fixing rods 2 are fixedly mounted with connecting plates 501. A set of reinforcing brackets 502 is fixedly mounted on one side of each set of fixing rods 2. The reinforcing brackets 502 are fixedly connected to the bracket 3. The connecting plates 501 can strengthen the structural strength between the two sets of fixing rods 2. The reinforcing brackets 502 can improve the structural strength of the bracket 3, thereby preventing deformation of the fixing rods 2 and the bracket 3.

[0024] Please see Figure 3 and Figure 4In this embodiment, two sets of fixing rings 601 are fixedly installed on the top of the bracket 3. The two sets of fixing rings 601 are symmetrically arranged. Two sets of buckles 602 are provided on the top of the bracket 3. The two sets of buckles 602 are respectively connected to the two sets of fixing rings 601. An elastic strap 603 is fixedly installed between the two sets of buckles 602. By setting the elastic strap 603, the top of the column supported by the bracket 3 can be tightened, making it more stable. By setting the buckles 602 and fixing rings 601, the two ends of the elastic strap 603 can be fixed. The buckles 602 can be easily installed and removed from the elastic strap 603. A sliding groove 701 is provided on one side of the fixing rod 2. An installation block 702 is provided inside the sliding groove 701. The installation block 702 is slidably connected to the fixing rod 2. An installation block 702 is fixedly installed on the top of the installation block 702. A damping spring 703 is installed and fixedly connected to the fixing rod 2. A mounting shaft 704 is fixedly installed on one side of the mounting block 702, and an auxiliary wheel 705 is provided on one side of the mounting block 702. The auxiliary wheel 705 is located outside the mounting shaft 704 and is rotatably connected to the mounting shaft 704. The mounting block 702 is supported and installed by the mounting shaft 704. The auxiliary wheel 705 is installed by the mounting shaft 704. The auxiliary wheel 705 can reduce friction, thereby assisting the fixing rod 2 in moving during transportation. The sliding groove 701 can be provided so that the mounting block 702 can slide along the sliding groove 701 when the auxiliary wheel 705 encounters unevenness, keeping the overall rotating tool stable. The damping spring 703 provides a certain shock absorption effect.

[0025] When working, first place the two sets of fixing rods 2 around the outer periphery of a set of chain vertical rings 1 of the scraper conveyor. Use the pin 4 to pass through the pin hole 201 and the chain vertical ring 1 to fix the fixing rod 2 and the chain vertical ring 1. Use the locking nut 402 to connect with the pin 4 through the threaded section 401. Rotate the locking nut 402 to one side of a set of fixing rods 2 to lock the pin 4 and prevent the pin 4 from accidentally coming out.

[0026] Based on the length of the transport column, a suitable number of special tools are fixed to the outer periphery of the chain link 1 at certain intervals using the above method. Then, the column is hoisted above the bracket 3, and the bracket 3 supports the column. The semi-circular arc structure of the bracket 3 can limit the movement of the column on both sides to prevent it from swaying left and right during transportation, thereby improving the safety factor and protecting the relevant equipment. The rubber pad 301 is in direct contact with the surface of the column, which can protect the surface of the column and prevent wear between it and the bracket 3. At the same time, it can increase the friction, making the column supported by the bracket 3 more stable.

[0027] The two ends of the elastic strap 603 can be fixed by the cooperation of the buckle 602 and the fixing ring 601, thereby fixing the elastic strap 603 to the top of the column. The elastic strap 603 can be used to tighten the top of the column supported by the bracket 3, making it more stable.

[0028] Once the column is fixed, during transportation, the auxiliary wheel 705 reduces friction, thus assisting the movement of the fixed rod 2. The damping spring 703 provides a certain shock absorption effect, making the column transportation more stable.

[0029] Through the above steps, the bracket 3 is supported and installed by two sets of fixing rods 2. The two sets of fixing rods 2 can clamp the chain link 1 in the middle. The pin 4 can be installed through the pin hole 201. The pin 4 can fix the two sets of fixing rods 2 to the chain link 1, thereby fixing the bracket 3 above the chain link 1 of the scraper conveyor. The bracket 3 supports and limits the transported column, preventing the column from swaying left and right during transportation, improving the safety factor and protecting the related equipment. This solves the problem that the column is often directly hoisted onto the scraper of the conveyor during transportation. Because the column is cylindrical, it sways left and right and back and forth during transportation, which can easily damage the conveyor equipment. When passing under the coal mining machine, the swaying may damage the sliding parts of the coal mining machine, such as the sliding shoes, which is both unsafe and prone to damage to the equipment.

[0030] 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.
