Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated component processing, and particularly relates to a steam curing device for prefabricated guardrail components. Background Art

[0002] Concrete prefabricated components are components used in construction engineering construction. Generally, common ones include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof truss beams for industrial factories, culvert frames, and precast concrete piles for foundation treatment, etc. Concrete prefabricated components are mostly preformed in factories using molds and undergo curing. When in use, they can be directly assembled and used. During the curing process of the formed concrete prefabricated components, steam curing is mostly adopted. Steam curing can effectively shorten the curing time of concrete, speed up the construction progress, and also avoid the influence of low temperature on concrete prefabricated components, reducing the difficulty of curing concrete prefabricated components in low temperature areas. However, during curing, it is mostly an open-air operation, resulting in the steam not being able to fully contact the prefabricated components, easily damaging the internal structure of the prefabricated components. A structure that can enable the steam to fully contact the prefabricated parts is proposed. Content of the Utility Model

For example, anti-slip adhesive tapes are provided on the frame 201 and the pressing plate 202. The purpose of this setting is to facilitate increasing the friction between the precast component and the contact part in this way, so as to prevent sliding displacement after it is fixed.

[0019] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific motor lining plate 204 recorded in the above embodiment. For example, a sealing rubber ring is provided at the connection between the lining plate 204 and the frame 101 and the shaft 203. The purpose of this setting is to facilitate increasing its airtight effect in this way.

[0020] Specifically, a lead screw 306 is rotatably connected in the frame 201. The lead screw 306 is threadedly connected to the pressing plate 202, and a lever 307 is fixedly connected to the lead screw 306.

[0021] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific lead screw 306 recorded in the above embodiment. For example, the lead screw 306 should be selected as a lead screw with a self-locking effect. The purpose of this setting is to facilitate preventing the pressing plate 202 from driving the lead screw 306 to rotate reversely in this way.

[0022] Specifically, external gears 205 are respectively fixedly connected to a plurality of the shafts 203. A plurality of the external gears 205 are meshed and connected to a gear ring 207, and the gear ring 207 is fixedly connected to the frame 101.

[0023] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific frame 101 recorded in the above embodiment. For example, universal wheels are provided at the bottom of the frame 101. The purpose of this setting is to facilitate controlling the movement of the device in this way.

[0025] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific main shaft 208 described in the above embodiment.

[0027] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific motor 209 described in the above embodiment. For example, the motor 209 should be selected as a motor with adjustable multi - speed gears. The purpose of this setting is to facilitate adjusting the rotation frequency of the frame 201 in this way.

[0028] Specifically, a reciprocating lead screw A 301 is rotatably connected in the groove on the frame 201.

[0029] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific reciprocating lead screw A 301 described in the above embodiment. For example, the purpose of selecting the reciprocating lead screw A 301 as a reciprocating lead screw is that when the slider thread - connected to the reciprocating lead screw moves to one end, its same - direction rotation can be continuously controlled, so as to quickly change the movement direction of the slider.

[0030] Specifically, a sliding cylinder 302 is thread - connected to the reciprocating lead screw A 301. Scrapers 303 are respectively fixedly connected to the upper and lower ends of the sliding cylinder 302, and the scrapers 303 are slidably connected to the frame 201.

[0031] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific scraper 303 described in the above embodiment. For example, the scraper 303 is made of a hydrophobic material. The purpose of this setting is to prevent it from adsorbing moisture, resulting in insufficient curing of the prefabricated parts.

[0032] Specifically, the frame 101 is fixedly connected to a steam generator 308 through the bent pipe at its top.

[0033] In the embodiment of the present utility model, relevant technicians place the prefabricated parts in the frame 201 respectively, and manually rotate the lever 307, so that the pressing plate 202 threadedly connected to the lead screw 306 starts to perform linear motion along its connection with the frame 201, so that the pressing plate 202 and the frame 201 cooperate with each other to fix the prefabricated parts. Subsequently, the relevant technicians close the hatch on the frame 101 and start the steam generator 308 to inject steam into the frame 101. At the same time, the motor 209 is started, so that the main shaft 208 fixedly connected to the output shaft of the motor 209 starts to rotate, so that the internal gear 206 fixedly connected to the main shaft 208 rotates synchronously, so that the internal gear 206 drives the external gear 205 meshed with it to start rotating, so that the external gear 205 rotates around the internal gear 206 while rotating on its own in cooperation with the gear ring 207 meshed with it, so that the external gear 205 drives the shaft 203 fixedly connected to its axis to start rotating, so that the frame 201 fixedly connected to the shaft 203 starts to rotate synchronously, so that the prefabricated parts fixed on the frame 201 start to rotate synchronously. During the rotation, the steam fully contacts the prefabricated parts. At the same time, during the rotation of the frame 201, the gear 304 starts to drive the reciprocating lead screw A301 to rotate in cooperation with the gear ring A305 meshed with it, so that the sliding cylinder 302 threadedly connected to the reciprocating lead screw A301 starts to perform linear motion, so that the scraper 303 wipes and smears the surface of the prefabricated parts during the reciprocating motion, improving the curing effect.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0035] The so-called fixed connection in this application means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0036] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix the components together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be fastened properly.

[0037] (2) Non-detachable connection: mainly refers to welding, riveting, and mortise joint fitting, etc. Since for disassembly, forging, sawing, or oxy-fuel cutting is required during maintenance or replacement, the spare parts generally cannot be reused. At the same time, during connection, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0038] As used in this application, the sliding connection refers to a component that can slide along a linear trajectory, and the hinge connection refers to a component that can rotate along an axial constraint.

[0039] In some cases, the sliding connection and hinge connection as used in this application can also be damped, so that the component has the ability to maintain at a desired position.

[0040] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
