Description

Technical Field

[0001] The invention relates to the technical field of concrete pipes, and in particular to a high-efficiency pipe-top steaming device. Background Art

[0002] As a trenchless construction technique, pipe jacking minimizes the impact on the surrounding environment and buildings during construction. Currently, rectangular pipe jacking, suitable for large cross-sections, long distances, and complex strata, has become mainstream and is being widely used in projects such as underground pedestrian passages, subway station entrances and exits, underground roadways, and urban integrated pipeline corridors. Pipe jacking offers advantages such as minimal impact on the surrounding environment, a small construction footprint, and low noise levels. It addresses challenges such as damage to roads and buildings during pipeline construction, and demonstrates its advantages in soil stabilization and environmental protection. Consequently, pipe jacking is becoming increasingly common in construction projects.

[0003] Concrete is a general term for engineering composite materials that are made by cementing aggregates into a whole. Concrete usually refers to cement as the cementing material, sand and stone as aggregates, mixed with water in a certain proportion, and obtained by mixing. It is also called ordinary concrete. It is widely used in civil engineering. With the increase in civil engineering projects, concrete production lines are becoming more and more mature, but there are still some problems with autoclaved aerated concrete production lines.

[0004] At present, during the autoclaving and aeration production line, there will be a lot of dust on the surface of the dried embryo, which will cause a large amount of dust to fall into the interior of the autoclave when it is pushed. In addition, the surface of the embryo will also fall off to a certain extent during the autoclave process. These wastes will affect the use of the bottom track of the autoclave and also bring certain difficulties to cleaning. The steam of the existing autoclaving device is often discharged at a fixed position, and the top tube embryo is autoclaved by filling the entire cavity. This not only requires a large amount of steam discharge, but also takes time to fill the steam. For the top tube, the steam has poor fluidity, resulting in different autoclaving temperatures at different parts, which ultimately makes the top tube embryo incomplete. Due to the lack of condensed water treatment, the steam is easily condensed into water droplets at the top of the cavity. The dripping of water droplets will cause damage to the surface of the top tube embryo being steamed. Therefore, improvements are made to the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an efficient top tube steaming device, which solves the problems of dust accumulation in the existing device affecting the operation of the device, incomplete steaming of the top tube embryo, and dripping of condensed water droplets causing damage to the surface of the top tube embryo.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An efficient top-tube steaming device comprises a tube body, a sealed door, and an evaporator. The evaporator is arranged on the tube body, and the sealed door is rotatably arranged at the opening of the tube body. A fixed rod and a spiral rod are symmetrically arranged inside the tube body. A support ring and a steaming device are mounted on the two fixed rods. A cylinder is arranged inside the tube body, and an output rod of the cylinder is connected to the support ring. A support device is provided between the support ring and the steaming device, and a top tube is placed on top of the support device.

[0008] The steaming device includes a support frame, a fan-shaped rack and an elastic member are installed on the side of the support frame, the fan-shaped rack performs reset movement through the elastic member, the upper and lower ends of the support frame are connected to rotating bearings, the two rotating bearings are both sleeved with spiral sleeves, and a guide plate is connected under the rotating bearing at the bottom end, the two spiral sleeves are respectively nested on the two spiral rods, and the spiral sleeves are engaged with the threads on the spiral rods, and a gear is fixedly sleeved on the spiral sleeve, and the two gears are engaged with the fan-shaped rack.

[0009] As a further solution of the present invention: the supporting device includes a track and a trolley, the track is arranged in the tube body and fixed between the supporting ring and the steaming device, and the trolley is arranged on the track.

[0010] As a further solution of the present invention: the gear has an incomplete tooth angle and is located in the same vertical plane as the sector rack.

[0011] As a further solution of the present invention: the sector rack includes rack 1 and rack 2, rack 1 and rack 2 are both quarter arc racks with the same structure, and rack 1 and rack 2 constitute a semicircular rack.

[0012] As a further solution of the present invention: rack 1 is engaged with the gear at the top, and rack 2 is engaged with the gear at the bottom. One rotation of the gear drives rack 1 and rack 2 to rotate a quarter of the distance of the support frame.

[0013] As a further solution of the present invention: steam exhaust pipes are provided at both ends of the side surfaces of the rack 1 and the rack 2, and the four steam exhaust pipes are arranged toward the support ring.

[0014] As a further solution of the present invention: sponge brushes are provided on the two steam exhaust pipes located on the first rack, and scraper brushes are provided on the two steam exhaust pipes located on the second rack.

[0015] Beneficial effects of the present invention:

[0016] 1. In the present invention, as the gear drives the sector rack to rotate, the four steam exhaust pipes will also rotate on the outer surface of the top pipe to perform steam curing, which allows the steam to quickly contact the surface of the top pipe. At the same time, the steam exhaust pipes will also move with the top pipe, which allows steam curing to be performed as soon as the steam is discharged. At the same time, it avoids the problem of filling the entire cavity to autoclave the embryo body of the top pipe, which requires a large amount of steam discharge and takes time to fill the steam. At the same time, the annular steam discharge also avoids the problem of poor steam fluidity causing the autoclaving temperature of different parts to be different, which ultimately leads to incomplete autoclaving of the embryo body of the top pipe.

[0017] 2. The sponge brush of the present invention rotates along with the steam exhaust pipe located in the upper semicircle, and the scraper brush rotates along with the steam exhaust pipe located in the lower semicircle. This allows the sponge brush to absorb water droplets condensed on the upper wall while the steam exhaust pipe rotates, while the scraper brush can gather waste on the lower wall into the drainage channel located at the lower end of the pipe body.

[0018] 3. The sponge brush rotates in the upper semicircle to absorb water droplets, and the scraper brush rotates in the lower semicircle to gather waste. This avoids the problem that the steam condenses into water droplets and drips at the top of the cavity due to the lack of a condensed water treatment device, causing damage to the surface of the embryo of the top pipe being steamed, and more dust and debris will fall on the surface of the dried embryo after it falls on the inside of the pipe body, affecting the use of the track at the bottom of the pipe body, and also causing certain difficulties in cleaning. At the same time, water droplets are processed on the upper surface and do not enter the lower surface, and dust is processed on the lower surface and does not enter the upper surface. This dry and wet separation setting makes the inside of the pipe body cleaner and avoids the problem of water droplets and dust combining to cause damage to the top pipe.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] like Figures 1-6 As shown, it is an efficient top tube steaming device, which includes a tube body 1, a sealed door 2 and an evaporator 3, wherein the evaporator 3 is arranged on the tube body 1 to provide steam for the tube body 1, and the sealed door 2 is rotatably arranged at the opening of the tube body 1 to perform on-off control of the steaming process;

[0029] Further Figure 2 As shown, fixed rods are symmetrically arranged on both sides of the tube body 1, and the two fixed rods are fixed on both sides of the horizontal direction of the tube body 1, and the two fixed rods are installed with a support ring 5 and a steaming device 7 from one side of the sealed door 2 to the inside, and the support ring 5 and the steaming device 7 can move horizontally on the fixed rods. Further, a cylinder 9 is fixedly connected to the lower end of the tube body 1 near the sealed door 2, and the output rod of the cylinder 9 is connected to the support ring 5. The cylinder 9 is provided on one side of the support ring 5. The above-mentioned support ring 5 and the steaming device 7 are limited by the fixed rods and can move together in the horizontal direction under the drive of the cylinder 9. At the same time, spiral rods 6 are fixedly connected to both ends of the vertical direction of the tube body 1. The two spiral rods 6 and the two fixed rods are distributed at equal angles around the central axis of the tube body 1. Further, the steaming device 7 is connected to the spiral rod 6 to drive the steaming device 7 to operate;

[0030] Further by Figure 2 As shown, a support device 4 is provided between the support ring 5 and the steaming device 7. The support device 4 connects the support ring 5 and the steaming device 7 at both ends, and a top pipe 8 is placed on the top of the support device 4 to drive the top pipe 8 to perform the steaming process.

[0031] Further Figure 3 and Figure 4As shown, the supporting device 4 includes a track 41 and a trolley 42, wherein the track 41 is arranged in the tube body 1 and fixed between the support ring 5 and the steaming device 7, the trolley 42 is arranged on the track 41 and can move on the track 41, the top tube 8 is arranged on the trolley 42, and the steaming device 7 presses against the trolley 42 from the front end to prevent the trolley 42 from sliding out;

[0032] Further Figure 4-Figure 6 As shown, the steaming device 7 includes a support frame 74, which is slidably mounted on two fixed rods, and a movable groove is provided on the side of the support frame 74, in which a fan-shaped rack 77 and an elastic member 78 are installed, wherein the fan-shaped rack 77 is reset by the elastic member 78, and further the upper and lower ends of the support frame 74 are fixedly connected to the rotating bearing 700 through the connecting block, and the two rotating bearings 700 are both sleeved with a spiral sleeve 75, and the bottom of the rotating bearing 700 is connected to a guide plate 79, wherein the two The spiral sleeves 75 are respectively nested on the two spiral rods 6, and the spiral sleeves 75 are meshed with the threads on the spiral rods 6. A gear 76 is fixedly sleeved on the end of the spiral sleeve 75 close to the support frame 74, and the two gears 76 are meshed with the sector rack 77. During the steaming process, as the cylinder 9 drives the support ring 5 to move, the support frame 74 of the steaming device 7 also moves, and the spiral sleeve 75 connected thereto can move and rotate on the spiral rod 6, which enables the gear 76 connected thereto to rotate together, thereby driving the sector rack 77 to rotate.

[0033] Further, the gear 76 is of incomplete tooth angle shape, and the half gear and the sector rack 77 are in the same vertical plane to form an intermittent meshing connection;

[0034] like Figure 5 and Figure 6 As shown, the sector rack 77 is slidably connected to the side of the support frame 74, and the sector rack 77 includes a rack 1 771 and a rack 2 772. The rack 1 771 and the rack 2 772 are both quarter-circular arc racks with the same structure. The rack 1 771 and the rack 2 772 form a semicircular rack, and the rack 1 771 and the rack 2 772 are not fixed. The rack 1 771 is engaged with the gear 76 at the top, and the rack 2 772 is engaged with the gear 76 at the bottom. When the gear 76 rotates one circle, it can just drive the rack 1 771 and the rack 2 772 to rotate a quarter of the distance of the support frame 74. Due to its incomplete tooth angle structure, the rack 1 771 and the rack 2 772 will quickly reset under the pull of the corresponding elastic member 78 after rotating a quarter of the distance of the support frame 74.

[0035] The two elastic members 78 are tension springs, and the distal ends of the rack 1 771 and the rack 2 772 are connected to the support frame 74 via the tension springs. The reset process occurs during the period when the gear 76 is not in contact with the rack 1 771 and the rack 2 772, and then the next cycle begins. That is, the rack 1 771 and the rack 2 772 continue to rotate a quarter of the circle of the support frame 74 under the drive of the gear 76.

[0036] Further Figure 4 As shown, both ends of the side surfaces of rack 1 771 and rack 2 772 are provided with steam exhaust pipes 71, which can discharge the steam in the evaporator 3 through the nozzle of the steam exhaust pipe 71 to the outer surface of the top pipe 8 through the conduit, and the four steam exhaust pipes 71 are arranged toward the support ring 5. Furthermore, sponge brushes 72 are provided on the two steam exhaust pipes 71 of rack 1 771, so that when the steam exhaust pipe 71 rotates, the sponge brushes 72 can absorb the water droplets condensed on the upper wall to avoid affecting the steaming. At the same time, scraper brushes 73 are provided on the two steam exhaust pipes 71 of rack 2 772, so that when the steam exhaust pipe 71 rotates, the scraper brushes 73 can gather the waste on the lower wall at the lower end of the inner part of the tube body 1. In the sewage channel, the sponge brush 72 rotates in the upper semicircle to absorb water droplets, and the scraper brush 73 rotates in the lower semicircle to gather waste materials. This avoids the problem that the steam is easily condensed into water droplets and drips at the top of the tube body 1 cavity due to the lack of a condensed water treatment device, causing damage to the surface of the embryo of the top pipe 8 being steamed, and a lot of dust and detached materials will fall on the surface of the dried embryo after falling on the inside of the tube body 1, affecting the use of the bottom track 41 of the tube body 1, and also bringing certain difficulties to cleaning. At the same time, water droplets are processed on the upper surface and do not enter the lower surface, and dust is processed on the lower surface and does not enter the upper surface. This dry and wet separation setting makes the inside of the tube body 1 cleaner, and also avoids the problem of water droplets and dust combining to cause damage to the top pipe 8.

[0037] During the steam curing process, as the gear 76 drives the sector rack 77 to rotate, the four steam discharge pipes 71 also rotate and steam curing on the outer surface of the top tube 8, which allows the steam to quickly contact the surface of the top tube 8. At the same time, the steam discharge pipes 71 also move with the top tube 8, which allows the steam to be discharged, so that the steam curing can be carried out while avoiding the problem of a large amount of steam discharge required to fill the entire cavity to autoclave the embryos in the top tube 8 and the time required to fill it. At the same time, the annular steam discharge also avoids the problem of poor steam fluidity, which causes different autoclaving temperatures at different parts and ultimately causes incomplete autoclaving of the embryos in the top tube 8.

[0038] Furthermore, during the rotation and movement of the spiral sleeve 75, the guide plate 79 will always face downward under the action of its own gravity and will not rotate with the rotation of the spiral sleeve 75, but can only move with it. The guide plate 79 mainly guides the waste in the sewage channel located at the lower end of the pipe body 1 to move toward the pipe mouth.

[0039] Working principle of the present invention:

[0040] During steaming, the airtight door 2 is opened, the top pipe 8 is placed on the trolley 42 above the track 41, and then the airtight door 2 is closed; the evaporator 3 starts to run to guide steam into the tube body 1, and the cylinder 9 pushes the support ring 5 to move inward, and the support ring 5 drives the steaming device 7 and the top pipe 8 to move. The movement of the steaming device 7 drives the spiral sleeve 75 to move, and the spiral sleeve 75 moves and rotates on the spiral rod 6, thereby driving the gear 76 to rotate. The rotation of the gear 76 drives the rack 1 771 and the rack 2 772 to rotate, and then drives the steam exhaust pipe 71, sponge brush 72 and scraper connected thereto. As the brush 73 rotates, and because the gear 76 is an incomplete tooth angle structure, the rack 1 771 and the rack 2 772 will quickly reset under the pull of the elastic member 78 after rotation. The reset process occurs during the period when the gear 76 and the fan-shaped rack 77 are not in contact. Then the next cycle begins, the steam exhaust pipe 71 starts to rotate to steam the top pipe 8. At the same time, the sponge brush 72 starts to absorb water droplets on the upper surface, and the scraper brush 73 collects dust on the lower surface; the cylinder 9 pushes the support ring 5 outward and then returns to the pipe mouth, and the steaming of the top pipe 8 is completed.

[0041] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
