Problems solved by technology

Therefore, the grate has the characteristics of large size and heavy weight; and the installation accuracy of the grate is high. In the process of hoisting this kind of incineration grate, the force of each lifting point is often uneven. It is easy to cause the deformation of the incineration grate, resulting in the installation accuracy not meeting the requirements and affecting the subsequent use. Due to the structural characteristics of the incineration grate itself, its upper end is inclined, and the traditional spreader cannot be stable, reliable and matched with the incineration grate. At the same time, according to different designs, the length of the incineration grate changes, and it is necessary to ensure the adaptability of the spreader to the length change

Embodiment 1

[0032] Such as Figures 1 to 6 , shown in 9 to 12, a length-adjustable hoisting device of a reciprocating vibration incineration grate, the upper end of the incineration grate is inclined, including a load beam 1 and a hanging beam mechanism, and the load beam 1 is horizontal;

[0033]The left and right ends of the upper end surface and the lower end surface of the load-bearing beam 1 are symmetrically provided with at least two sets of lifting lugs 2, each set includes a lifting lug 2 at the left and right ends, and the distance between the two lifting lugs 2 in each group is different. The two lifting lugs 2 are left and right symmetrical. Here, three sets of lifting lugs 2 are respectively arranged on the upper end surface and the lower end surface respectively, and the upper end surface and the lower end surface respectively have six lifting lugs 2. One-to-one correspondence, and the lifting lug 2 on the upper end surface of the load-bearing beam 1 is parallel to the lengt...

Embodiment 2

[0040] Such as Figure 7 and 8 As shown, on the basis of Embodiment 1, the front ends of the bottoms of the two longitudinal suspension beams 6 have butt holes 16, and the bottom ends of the extensions 8 at the bottom of the two vertical suspension beams 6 also have butt holes 16, and the butt holes 16 are used for matching with the inclined shape. The hoisting holes at the high point and the low point of the incineration grate correspond respectively, and bolts pass through the corresponding butt joint holes 16 and the hoisting holes to realize the fixed connection between the incineration grate and the two vertical hanging beams 6 .

Embodiment 3

[0042] Such as figure 1 , 4 , 5, 8, 10 and 11, on the basis of embodiment 2, the load-bearing beam 1 is an I-beam, and a reinforcing plate-17 is welded and fixed between the top plate, the web and the bottom plate of the load-bearing beam 1, and strengthens Plate 1 17 is perpendicular to the three, and reinforcement plate 2 18 is welded and fixed between the top plate and bottom plate of load beam 1, and reinforcement plate 2 18 is parallel to the web; transition beam 12 is flat plate, welded on the side of transition beam 12 The third reinforcement plate 19 is fixed, and the third reinforcement plate 19 is perpendicular to the transition beam 12; the fourth reinforcement plate 20 is welded and fixed between the top plate, the web and the bottom plate of the longitudinal suspension beam 6, and the fourth reinforcement plate 20 is perpendicular to the three, Between the top plate and the bottom plate of the vertical suspension beam 6, a reinforcement plate 5 21 is welded and f...

Abstract

The invention relates to the technical field of incineration grate mounting, and discloses a length-adjustable hoisting and conveying device for a reciprocating type vibration incineration grate. At least two groups of hoisting lugs which are bilaterally symmetric are arranged at the upper end and the lower end of a load-bearing beam; each group of hoisting lug comprises the left hoisting lug andthe right hoisting lug; the two hoisting lugs at the upper end are each connected with a hoisting cable I; the two hoisting lugs at the lower end are each connected with two hoisting cables II; two longitudinal hoisting beams are fixedly connected through a cross beam; two hoisting lugs which are symmetrical in a front and back manner are arranged at the upper end faces of the two longitudinal hoisting beams and are each connected with the two hoisting cables II at the same end of the load-bearing beam correspondingly; the front ends of the two longitudinal hoisting beams are fixedly connectedwith a high point of the incinerator grate; an extension parts of the rear ends of the two longitudinal hoisting beams are fixedly connected with a low point of the incinerator grate; the lengths ofthe extension parts are the same as a height difference between the high point and the low point; mounting through holes and connecting holes are formed in the two ends of the longitudinal hoisting beams; the cross beam is provided with at least two groups of mating holes; each group of mating holes comprises the two mating holes at the left end and the right end of a top plate and the two matingholes at the left end and the right end of the bottom plate; the connecting holes are fixedly connected with the mating holes by bolts; and the distance between each group of mating holes correspondsto the distance between the left hoisting lug and the right hoisting lug at the lower end face of the load-bearing beam. The hoisting and conveying are stable and reliable, a hoisting point is stressed uniformly, the mounting accuracy of the incinerator grate is guaranteed, and the length change of the incinerator grate is adapted.

Description

technical field [0001] The invention relates to the technical field of installation of an incineration grate, in particular to a length-adjustable hoisting device for a reciprocating vibrating incineration grate. Background technique [0002] The reciprocating vibrating incineration grate is currently the most commonly used household waste incinerator in China. Take the 500t / d incinerator developed by Everbright Changzhou Environmental Protection Company as an example. 11m and a width of about 2m. Therefore, the grate has the characteristics of large size and heavy weight; and the installation accuracy of the grate is high. In the process of hoisting this kind of incineration grate, the force of each lifting point is often uneven. It is easy to cause the deformation of the incineration grate, resulting in the installation accuracy not meeting the requirements and affecting the subsequent use. Due to the structural characteristics of the incineration grate itself, its upper ...
