[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] like Figures 1-5 As shown, this utility model provides a technical solution: a special track structure for replacing heating network heaters, comprising: Longitudinal channel steel 1, the quantity of longitudinal channel steel 1 is set to two, and the two longitudinal channel steel 1 are arranged in parallel; Longitudinal track mechanism 2 is set on top of longitudinal channel steel 1 and is used to provide a moving path for support mechanism 3; Support mechanism 3 is located on top of longitudinal track mechanism 2 and is used to support the equipment. The longitudinal track mechanism 2 includes a vertical plate 21, which is fixedly installed on the top of the longitudinal channel steel 1. The top of the longitudinal channel steel 1 forms a parallel track 22 located inside the vertical plate 21. A base plate 23 is fixedly installed at the bottom of the inner cavity of the parallel track 22. Through the design of the longitudinal channel steel 1 and the vertical plate 21, the parallel track 22 can be formed. The support mechanism 3 can slide on the parallel track 22 to move the equipment. It has good stability and high positioning accuracy.
[0023] As one implementation method in this embodiment, such as Figure 2 , Figure 3 As shown, a movable plate 24 is detachably connected to the top of the base plate 23. A protruding limiting block 25 is fixedly installed on the top of the movable plate 24. The protruding limiting block 25 is used to limit the movement of the support mechanism 3 to increase safety. The movable plate 24 is detachably connected to the top of the base plate 23 by bolts. The protruding limiting block 25 can be replaced when damaged.
[0024] As one implementation method in this embodiment, such as Figure 3 As shown, a T-shaped groove 26 is provided at the end of the protruding limiting block 25. A movable block 27 is movably inserted into the inner cavity of the T-shaped groove 26. A rubber block 28 is fixedly connected to the side of the movable block 27. A through hole 29 is provided on the top of the rubber block 28. Through the design of the rubber block 28, the force generated by the overall contact between the support mechanism 3 and the protruding limiting block 25 can be buffered, thereby increasing the safety and stability of the equipment. When the rubber block 28 is damaged, a new rubber block 28 can be replaced by pulling and inserting the movable block 27 into the inner cavity of the T-shaped groove 26.
[0025] As one implementation method in this embodiment, such as Figure 5 As shown, the support mechanism 3 includes a transverse support beam 31. The number of transverse support beams 31 is set to two. One transverse support beam 31 has a first connecting arm 311 fixedly connected to its side, and the other transverse support beam 31 has a second connecting arm 312 fixedly connected to its side. The transverse support beams 31 are used to directly support the equipment. The design of the first connecting arm 311 and the second connecting arm 312 facilitates the connection between the two transverse support beams 31.
[0026] As one implementation method in this embodiment, such as Figure 5As shown, both the first connecting arm 311 and the second connecting arm 312 have adjustment holes 313 at their tops. A pin 314 is movably inserted into the inner cavity of the adjustment hole 313, and a nut 315 is threaded to the end of the pin 314. If it is necessary to adjust the span of the two transverse support beams 31 to accommodate equipment of different sizes, the nut 315 is rotated off the end of the pin 314, and then the pin 314 is pulled out from the inside of the adjustment hole 313. The span of the two transverse support beams 31 is then adjusted. After adjustment, the pin 314 is inserted into the inner cavity of the adjustment hole 313, and the nut 315 is rotated on and installed.
[0027] As one implementation method in this embodiment, such as Figure 4 As shown, a through groove 32 is provided at the bottom of the transverse support beam 31. An assembly block 33 is movably inserted into the inner cavity of the through groove 32. A trolley 34 is fixedly installed at the bottom of the assembly block 33. A pulley 35 is fixedly installed at the bottom of the trolley 34. The pulley 35 is movably connected in the inner cavity of the parallel track 22. After the transverse support beam 31 directly supports the equipment, it can slide as a whole inside the parallel track 22 with the help of the trolley 34 and the pulley 35, so as to realize the smooth pulling out of the heat network heater and the precise positioning of the new equipment, with high positioning accuracy.
[0028] As one implementation method in this embodiment, such as Figure 4 As shown, an assembly block 2 36 is fixedly installed on the inner wall of the through groove 32. An assembly pin 37 is detachably connected to the inner cavity of the assembly block 1 33 and the assembly block 2 36. The transverse support beam 31 and the trolley 34 are detachably connected. The modular design allows for replacement if one part is damaged. When separating, loosen the bolts on the assembly block 2 36, then pull the assembly pin 37 out of the inside of the assembly block 2 36. At the same time, the assembly pin 37 is removed from the inside of the assembly block 1 33. Then, the assembly block 1 33 is pulled out of the inside of the through groove 32, thus completing the separation of the transverse support beam 31 and the trolley 34.
[0029] Working principle: During use, the transverse support beam 31 is used to directly support the equipment. The transverse support beam 31 can slide as a whole inside the parallel track 22 with the help of the trolley 34 and pulley 35, so as to realize the smooth pulling out of the heat network heater and the precise positioning of the new equipment. During the process, the protruding limit block 25 is used to limit the movement of the support mechanism 3 to increase safety. During maintenance, if it is necessary to adjust the span of the two transverse support beams 31 to accommodate equipment of different sizes, rotate the nut 315 off the end of the pin 314, then pull the pin 314 out from the inside of the adjustment hole 313, and then adjust the span of the two transverse support beams 31. After adjustment, insert the pin 314 into the inner cavity of the adjustment hole 313 and rotate the nut 315 back on.
[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
