[0029] Example 1

[0030] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a roller device for transferring boiler furnace scaffolding pipes, the device comprising a main body mechanism 100 and a fixed bracket 200;

[0031] Among them, the main mechanism 100 includes a mounting shaft 101, an oiling head 102 arranged on the outside of the mounting shaft 101, a roller 103 rotatably connected to the outside of the mounting shaft 101, a pressure block 104 is arranged inside the mounting shaft 101, a trigger rod 105 is slidably connected inside the mounting shaft 101, and a closing component 106 is arranged inside the mounting shaft 101.

[0032] Specifically, an oil storage cavity 101a is provided inside the installation shaft 101, an installation cavity 101b is provided inside the installation shaft 101, a slot 101c is provided on one side of the installation cavity 101b, and the pressing block 104 is slidably connected inside the installation cavity 101b.

[0033] Furthermore, an auxiliary disk 101d is fixedly connected to the outer side of the installation shaft 101, and a convex ring 101e is fixedly connected to the inner wall of the auxiliary disk 101d.

[0034] Furthermore, a clamping hole 103 a is formed on the inner wall of the drum 103 , a guide groove 103 b is formed on the inner wall of the drum 103 , and a groove 103 c is formed on the outer side of the drum 103 .

[0035] Preferably, a slot 104a is provided on the outer side of the pressing block 104, an inclined surface 104b is provided on the outer side of the pressing block 104, one end of the pressing block 104 is fixedly connected to a first spring 104c, and the other end of the first spring 104c is connected to the inner wall of the installation cavity 101b.

[0036] It should be noted that the outer side of the fixing bracket 200 is fixedly connected to the supporting block 201 , the outer side of the supporting block 201 is provided with a mounting groove 202 , and the outer side of the fixing bracket 200 is threadedly connected to a bolt 203 .

[0037] When in use, first install the fixing bracket 200 on the manhole door by means of the bolt 203, then place the mounting shaft 101 inside the mounting groove 202, and then squeeze the inclined surface 104b of the pressing block 104 inside the mounting shaft 101 against the bottom end of the mounting groove 202. Under the squeezing, the pressing block 104 will be urged to squeeze the first spring 104c, and finally the clamping groove 104a will be engaged with the mounting groove 202, thereby completing the limit fixation of the mounting shaft 101, and squeezing the pressing block 104 by the first spring 104c, thereby improving the installation effect of the mounting shaft 101 and the mounting groove 202, and further ensuring the stability of the mounting shaft 101 after installation.

[0038] In summary, after the installation shaft 101 is installed on the fixing bracket 200, the first spring 104c squeezes the pressing block 104 to improve the installation effect of the installation shaft 101 and the installation groove 202, and further ensure the stability of the installation shaft 101 after installation.

[0039] Example 2

[0040] Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that an inner hole 101f is formed on the inner wall of the mounting shaft 101, and an outer hole 101g is formed on the outer side of the mounting shaft 101. The diameter of the inner hole 101f is larger than the diameter of the outer hole 101g, and the inner hole 101f is coaxially arranged with the outer hole 101g, and the closing component 106 is arranged inside the outer hole 101g.

[0041] Furthermore, the trigger rod 105 is fixedly connected to the pressing block 104 , and an oblique groove 105 a is formed on the outer side of the trigger rod 105 .

[0042] Furthermore, the closing component 106 includes a sleeve 106a, a limiting rod 106b fixedly connected to one end of the sleeve 106a, and a second spring 106c fixedly connected to the inside of the sleeve 106a, one end of the second spring 106c is fixedly connected to a sealing block 106d, and one end of the sealing block 106d is provided with an oil leakage groove 106e.

[0043] Preferably, the limiting rod 106b is disposed inside the inclined groove 105a and slides inside the inclined groove 105a, the sealing block 106d is slidably connected inside the outer sleeve 106a, and the sealing block 106d is slidably connected to the outer hole 101g.

[0044] During use, when the card slot 104a is engaged with the installation slot 202, the sliding pressure block 104 will drive the trigger rod 105 to slide synchronously, and drive the limit rod 106b to move under the design of the inclined groove 105a. The limit rod 106b will drive the sealing block 106d to move and leave the inside of the card hole 103a through the outer sleeve 106a. At this time, the roller 103 can rotate on the outside of the installation shaft 101.

[0045] It is only necessary to transport various scaffolding pipes to the interior of the furnace through the surface of the drum 103. Compared with manual handling, it not only reduces the labor burden of personnel, but also improves the overall work efficiency of minor repairs to a certain extent.

[0046] In summary, when the installation shaft 101 is installed on the fixed bracket 200, it can not only ensure the stability after installation, but also unlock the roller 103 to ensure that the roller 103 can rotate at this time to assist in the transportation of various scaffolding pipes.

[0047] Example 3

[0048] Reference Figure 1 to Figure 7

[0049] This is the third embodiment of the present invention, which is based on the second embodiment in that: after the sealing block 106d slides, the oil leakage groove 106e is connected to the outer hole 101g, and the lubricating oil in the oil storage chamber 101a can enter the clamping hole 103a through the outer hole 101g and the oil leakage groove 106e, and finally flow into the guide groove 103b, so that when the roller 103 rotates, the lubricating oil in the guide groove 103b will continuously lubricate the installation shaft 101 and the roller 103, ensuring the smoothness of the rotation of the roller 103. At the same time, during the continuous rotation of the roller 103, the lubricating oil will continuously enter the clamping hole 103a and the guide groove 103b, achieving continuous lubrication without manual lubrication by personnel.

[0050] After the equipment is used, the installation shaft 101 is removed. At this time, the first spring 104c will drive the pressure block 104 and the trigger rod 105 to reset, and the roller 103 will be rotated at the same time. Under the elasticity of the second spring 106c, the sealing block 106d will be driven to re-engage the clamping hole 103a and then stop rotating. At this time, the outer hole 101g is blocked by the sealing block 106d and cannot continue to leak lubricating oil, which can effectively store the lubricating oil to avoid waste. In addition, the roller 103 cannot rotate, which is not only convenient for placing the equipment, but also can avoid the relative rotation of the installation shaft 101 and the roller 103 during the placement process, which causes the waste of lubricating oil inside the guide groove 103b, thereby realizing the maximum saving of lubricating oil.

[0051] In summary, the mounting shaft 101 fixed to the bracket 200 not only ensures stability, but also unlocks the roller 103 so that it can rotate freely. This helps to move various scaffolding pipes and automatically lubricate the equipment. In addition, it can effectively store lubricating oil to avoid waste.
