[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] like Figure 1-3 As shown, the utility model is a double-line chain loop conveying mechanism for a liquefied gas production line, the conveying mechanism is composed of a plurality of conveying units connected end to end in sequence to form a rectangular ring-shaped circulating conveying line, each conveying unit includes a power device 2, a driving wheel group 3, a driven wheel group 4, a double chain group 5, a chain groove 6 and a support frame 7;

[0031] like Figure 2-3 As shown, the structure of the driving wheel group 3 is that a driving wheel is fixedly installed at both ends of the driving wheel shaft, and the output shaft of the power device 2 is fixedly connected to the driving wheel shaft, and the power device 2 drives the driving wheel shaft to rotate slowly and uniformly;

[0032] The structure of the driven wheel set 4 is that a driven wheel is fixedly installed at each end of the driven wheel shaft;

[0033] The double chain set 5 includes two annular transmission chains arranged in parallel, each transmission chain is sleeved on the corresponding driving wheel and driven wheel, the upward chain and the downward chain of each transmission chain are placed in the chain groove 6, and the top surface of the upward chain is higher than the top surface of the chain groove 6, and the chain groove 6 is fixed to the ground through a plurality of support frames 7, and the chain groove 6 where the upward chain is placed is provided with an elongated through hole for the top of the driving wheel and the driven wheel to penetrate and extend to the top of the chain groove 6;

[0034] The head-to-tail connection of the conveying units is achieved by arranging two upward chains at the head end of one conveying unit between two upward chains at the tail end of another conveying unit, and the upward chains of the two conveying units are located in the same plane;

[0035] A seat frame 1 fixed to the ground is provided at the head and tail connection positions of the two conveying units, the power device 2 is fixed on the seat frame 1, and the driving wheel shaft and the driven wheel shaft are both installed on the seat frame 1 through a bearing seat 9.

[0036] The power device 2 includes a variable speed motor and a reduction box. The output shaft of the variable speed motor is connected to the input shaft of the reduction box, and the output shaft of the reduction box is fixedly connected to the driving wheel shaft.

[0037] When the utility model is working, the power devices 2 of all the conveying units drive all the corresponding double chain groups 5 to run in one direction of the conveying line, so as to realize the cyclic operation and conveying of the entire annular conveying line.

[0038] Working principle:

[0039] The variable speed motor of the power device 2 of all conveying units is adjusted to the corresponding speed according to the system, so that it drives the driving wheel group 3 to rotate after being decelerated by the reduction box, and realizes the same-direction and same-speed conveying operation of all double chain groups 5. The liquefied gas cylinder is placed vertically on the two upward chains of the double chain group 5, and the chain supports the liquefied gas cylinder to move on the conveyor line, thereby realizing the mechanized transfer of the liquefied gas cylinder. By setting multiple process equipment on the entire conveyor line, mechanical and automated transfer between multiple process points can be easily realized, saving labor input costs and reducing the labor intensity of staff, thereby reducing production input costs and improving work efficiency and work safety.

[0040] Since the conveyor line is a rectangular ring, the conveying speeds of the inner and outer chains at the corners are different, which can easily lead to bottle overturning. Therefore, a corner guide mechanism 8 is installed at all corners of the conveyor line to prevent the liquefied gas cylinder from falling.

[0041] like Figure 4 As shown, the corner guide mechanism 8 includes a single plate arc groove 81, an arc rod 82 and a vertical rod 83;

[0042] The side close to the center of the rectangular ring-shaped conveyor line is taken as the inner side, and the single-plate arc groove 81 is an arc-shaped chain groove with side plates only on the inner side, and no side plates are set on the outer side. On the one hand, the chains at the corner position basically squeeze the inner side plates, and on the other hand, the possibility of friction between the chains and the outer side plates is reduced. The two single-plate arc grooves 81 are arranged in parallel at the corner position of the conveyor line and the two ends are fixedly connected to the corresponding chain grooves 6 respectively. The two chains of the double chain group 5 are respectively placed in the two single-plate arc grooves 81 to form two parallel arc angle chains. The single-plate arc groove 81 is fixed to the ground by multiple support frames 7. An arc rod 82 is arranged on the outer side and the inner side of the corner position of the conveyor line. The arc rod 82 is fixed to the support frame 7 by multiple vertical rods 83. When the liquefied gas cylinder enters the corner position, the arc rod 82 can effectively prevent the bottle from falling over and keep the liquefied gas cylinder in an upright state during corner transportation.

[0043] The thickness of the side plate of the single plate arc groove 81 is greater than the thickness of the side plate of the chain groove 6. When conveying at a corner position, the chain is generally squeezed inward, so the side plate needs to be thickened to enhance its pressure-bearing performance.

[0044] When the liquefied gas cylinder is vertically placed on the two upward chains of the double chain group 5 , the height of the arc rod 82 corresponds to the middle of the body of the liquefied gas cylinder, so that the liquefied gas cylinder is clamped between the two arc rods 82 more effectively.

[0045] In the present invention, in order to more clearly show the positional relationship of each component, Figure 1 , 2 4 , the double chain set 5 is omitted. In fact, the two chains of the double chain set 5 are placed in the corresponding chain groove 6 and the single plate arc groove 81.

[0046] like Figure 5 As shown, the transmission chain is an annular chain formed by connecting a plurality of Y-shaped thick blocks end to end in sequence, one end of the Y-shaped thick block is a single-head head end and the other end is a double-head tail end, the single-head head end of the Y-shaped thick block is clamped in the gap of the double-head tail end of the previous Y-shaped thick block and is rotatably connected thereto through a rotating shaft, and a hole is reserved in the gap of the double-head tail end for the teeth of the driving wheel and the driven wheel to be inserted. The chain formed by the above structure has a flat top surface when placed in the chain groove, which is conducive to smoothly driving the liquefied gas cylinder for transportation.

[0047] The inner bottom surface and inner side surface of the chain groove 6 and the single plate arc groove 81 are both installed with oil-containing nylon lining plates, so that when the transmission chain moves inside them, it has the advantages of anti-static and wear resistance, thereby improving its service life and safety.
