Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0028] Referring to Figures 1 to 5 as shown, this embodiment provides a geopolymer concrete curing equipment, including:

[0029] The support includes several vertical columns 1. The several vertical columns 1 are symmetrically arranged in pairs. A scissor assembly 2 is hinged between two vertical columns 1 on the same side. A folding cross beam 3 is hinged between two mutually symmetric vertical columns 1. A plurality of mounting seats 4 are fixedly connected below the folding cross beam 3, and mounting holes 5 are provided on the mounting seats 4.

[0030] The covering cloth 6 is covered on the support.

[0031] The steam pipes 7 are provided with air outlet holes at the bottom. There are multiple steam pipes 7, which are evenly inserted into a plurality of coaxially arranged mounting holes 5. One end of the steam pipe 7 is closed, and the other end extends out of the covering cloth 6 and is connected to a steam generator 8.

[0032] In this application, when the support is idle or in transportation, the scissor assembly 2 contracts, causing the vertical columns 1 to approach each other in the front-rear direction, and the folding cross beam 3 folds, causing the vertical columns 1 to approach each other in the left-right direction. The entire support can be contracted to reduce its volume, facilitating transportation or storage. When in use, the support is unfolded in the front-rear and left-right directions and erected above the oligomer concrete. The covering cloth 6 is covered outside the support. Then, the steam pipes 7 are inserted into the mounting holes 5, with the air outlet holes facing downwards, and one end passes through the covering cloth 6 and is connected to the steam generator 8. The steam generator 8 generates steam, and the steam passes through the steam pipes 7 and is evenly ejected through the air outlet holes into the space formed by the covering cloth 6 and the support, performing steam curing on the oligomer concrete covered by the bottom of the support and the covering cloth 6. The covering cloth 6 and the steam pipes 7 of this application can be detachably transported and stored separately. The support can be folded and contracted to a smaller volume. This local oligomer concrete curing equipment is not only convenient for transportation and storage, but also convenient and fast for installation and erection, and is more convenient for the curing of oligomer concrete.

[0033] In a further optimized solution, the steam pipe 7 includes a head 701 and several short pipes 702. One end of the short pipe 702 is provided with internal threads, and the other end is correspondingly provided with external threads. The several short pipes 702 are connected end to end by threading. One end of the head 701 is closed, and the other end is provided with external threads. The head 701 is threadedly connected to one end of the short pipe 702, making one end of the steam pipe 7 closed. The open end of the steam pipe 7 is connected to the steam generator 8 through a connecting hose 9.

[0034] The steam pipe 7 is formed by splicing several short pipes 702 end to end. According to the stretched length of the support, an appropriate number of short pipes 702 can be selected for splicing to meet the needs of different curing lengths. The head 701 blocks one end of the steam pipe 7 to prevent steam from ejecting from the end of the steam pipe 7 and damaging the covering cloth 6.

[0035] In a further optimized solution, the scissor assembly 2 includes two scissor rods 201 that are cross-hinged. The tops of the scissor rods 201 of two adjacent scissor assemblies 2 are hinged through an upper hinge shaft 202, and the bottoms are hinged through a lower hinge shaft 203. The upper hinge shaft 202 is fixedly connected to the outside of the top of the vertical column 1, and a chute 10 is provided on the outer wall of the vertical column 1. The lower hinge shaft 203 is slidably connected in the chute 10.

[0036] Pulling the two vertical columns 1 can push the scissors rods 201 of the scissors assembly 2 to expand and contract. When expanding and contracting, the top of the scissors rod 201 remains stationary, and the bottom moves up and down along the chute 10. When moving up, the distance between the vertical columns 1 elongates, and when moving down, the distance between the vertical columns 1 shortens.

[0037] In a further optimized solution, the chute 10 is a T-shaped groove. One end of the lower hinge shaft 203 close to the chute 10 is fixedly connected with a T-shaped rod, and the T-shaped rod is slidably connected in the chute 10.

[0038] The T-shaped groove and the T-shaped rod can prevent the lower hinge shaft 203 from slipping out of the chute 10.

[0039] In a further optimized solution, the folding cross beam 3 includes a first folding beam 301 and a second folding beam 302. One end of the first folding beam 301 and the second folding beam 302 close to each other is hinged to each other, and the other ends away from each other are respectively hinged to the tops of the two vertical columns 1. The first folding beam 301 and the second folding beam 302 are hinged to the front side of the vertical column 1; the mounting seats 4 are uniformly fixedly connected to the bottoms of the first folding beam 301 and the second folding beam 302.

[0040] When the first folding beam 301 and the second folding beam 302 are folded towards each other, the distance between the two vertical columns 1 shortens. When the first folding beam 301 and the second folding beam 302 are unfolded away from each other, the distance between the two vertical columns 1 elongates.

[0041] In a further optimized solution, a reinforcing rod 303 is rotatably connected to the front side of the first folding beam 301. An opening 304 is formed at the bottom of the end of the reinforcing rod 303 away from the first folding beam 301. A plurality of limiting columns 305 are uniformly fixedly connected to the front side of the second folding beam 302, and the opening 304 is clamped on the limiting columns 305.

[0042] After the relative positions between the first folding beam 301 and the second folding beam 302 are determined, rotate the reinforcing rod 303 to make the opening 304 on the reinforcing rod 303 clamped on the appropriate limiting column 305. The folding degrees of the first folding beam 301 and the second folding beam 302 are different, and the limiting columns 305 clamped by the opening 304 are different. After the opening 304 is clamped on the limiting column 305, the folding angle between the first folding beam 301 and the second folding beam 302 can be further fixed, making the structure more stable.

[0043] In a further optimized solution, a telescopic rod 11 is slidably connected in the vertical column 1. A plurality of positioning holes 12 are formed on the telescopic rod 11. A pin hole 13 is formed at the bottom end of the vertical column 1. A positioning pin 14 is inserted into the pin hole 13, and the positioning pin 14 passes through the pin hole 13 and the positioning hole 12 to fix the telescopic rod 11.

[0044] The telescopic rod 11 can be telescoped within the vertical column 1 to adjust the height of the bracket; the pin hole 13 can pass through different positioning holes 12 to limit the bracket at different heights.

[0045] In a further optimized solution, a universal wheel 15 is fixedly connected to the bottom of the telescopic rod 11.

[0046] The universal wheel 15 facilitates the telescopic movement of the vertical column 1.
