Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated component processing, and particularly relates to a vibrating device for precast guardrail concrete. Background Technique

[0002] Precast concrete components are components used in construction engineering. Commonly seen 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. Precast concrete components are mostly preformed in factories using molds. When pouring large guardrails with irregular structures, the concrete often forms unevenly in the mold and is prone to causing hollowing. Now, a structure that can evenly fill the mold with concrete is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a vibrating device for precast guardrail concrete, which solves the above problems.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A vibrating device for precast guardrail concrete includes a frame, and further includes: a vibrating assembly for evenly filling the concrete; the vibrating assembly includes a slide plate, a push rod, and an eccentric wheel. One end of the push rod is hinged to the slide plate, the other end of the push rod is rotatably connected to the eccentric part of the eccentric wheel, and the eccentric wheel is rotatably connected to the frame.

[0005] Beneficial Effects

[0006] The utility model provides a vibrating device for precast guardrail concrete, which has the following beneficial effects compared with the prior art:

[0007] Related technicians place the mold in the groove of the skateboard, start grouting while starting the motor, so that the main shaft fixedly connected to the center of the transmission gear rotates synchronously, so that the main shaft drives the eccentric wheel fixedly connected thereto to start rotating, so that the push rod rotatably connected to the eccentric part of the eccentric wheel starts to perform circular motion, so that the push rod starts to push the skateboard hinged thereto, so that the skateboard performs linear motion along its connection with the slide bar, so that the mold placed in the groove of the skateboard starts to move synchronously, so that the mortar in it, under the action of inertia, is evenly filled into the mold, preventing the appearance of hollowing due to uneven mortar filling in some areas. At the same time, when the skateboard moves, it synchronously pushes the rotating cylinder to rotate, thereby reducing its frictional force and making the skateboard move more quickly. At the same time, the rack fixedly connected to the skateboard moves synchronously during the movement of the skateboard, so that the rack drives the gear meshed with it to start rotating, so that the connecting rod fixedly connected to the center of the gear starts to rotate synchronously, so that the fan blade fixedly connected to the top of the connecting rod starts to rotate, and the mortar falling on both sides of the skateboard is pushed away by the rotation of the fan blade, so as to prevent the mortar from flowing into the skateboard along the gap between the mold and the skateboard and causing the mold to be unable to be taken out after it solidifies.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0015] Please refer to Figures 1 to 4, provided by an embodiment of the present utility model, a precast guardrail concrete vibrating device, including a frame 101, further including:

[0016] A vibration assembly 2 for making the concrete filling uniform;

[0017] The vibration assembly 2 includes a slide plate 201, a push rod 202 and an eccentric wheel 203. One end of the push rod 202 is hinged to the slide plate 201, and the other end of the push rod 202 is rotatably connected to the eccentric part of the eccentric wheel 203. The eccentric wheel 203 is rotatably connected to the frame 101.

[0018] 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 slide plate 201 described in the above embodiment. For example, the inner wall of the slide plate 201 is provided with an anti-slip gasket. The purpose of this setting is to facilitate filling the connection gap between the mold and the slide plate 201 through the anti-slip gasket, thereby preventing it from being displaced during the sliding process of the slide plate 201.

[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 push rod 202 described in the above embodiment. For example, the push rod 202 should be made of a material processed integrally. The purpose of this setting is to facilitate preventing the push rod 202 from being broken by force in this way.

[0020] Specifically, the slide plate 201 is slidably connected to a slide rod 206. The slide rod 206 is fixedly connected to the frame 101. A plurality of rotating shafts 205 are rotatably connected to the bottom of the frame 101, and a rotating cylinder 204 is fixedly connected to each of the plurality of rotating shafts 205.

[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 slide rod 206 described in the above embodiment. For example, the slide rod 206 is provided with a damping rubber strip. The purpose of this setting is to facilitate increasing the friction at its connection in this way, so that the slide plate 201 can slide smoothly under the push of the push rod 202.

[0022] Specifically, a main shaft 207 is fixedly connected to the other side axis of the eccentric wheel 203. The main shaft 207 is rotatably 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 main shaft 207 described in the above embodiment. For example, a bearing ring is provided at the connection between the main shaft 207 and the frame 101. The purpose of this setting is to facilitate reducing the friction during its rotation in this way, thereby preventing the occurrence of shaft breakage.

[0024] Specifically, racks 301 are fixedly connected to both sides of the skateboard 201, and a plurality of gears 302 are respectively meshed with the two racks 301.

[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 skateboard 201 described in the above embodiment. For example, there should be multiple size models available for the skateboard 201. The purpose of this setting is to facilitate increasing the adaptability of the device in this way, so that it can be compatible with molds of multiple size models.

[0026] Specifically, a connecting rod 303 is fixedly connected to the center of the gear 302. The connecting rod 303 is rotatably connected to the frame 101, and a fan blade 304 is fixedly connected to the top of the connecting rod 303.

[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 fan blade 304 described in the above embodiment. For example, the fan blade 304 can be made of a water-absorbing material. The purpose of this setting is to facilitate adsorbing the moisture in the mortar through the water-absorbing material, thereby preventing it from flowing into the gap at the connection between the skateboard 201 and the mold.

[0028] Specifically, a transmission gear 208 is fixedly connected to the main shaft 207. The transmission gear 208 is meshed with the gear fixedly assembled on the output shaft of the motor 209, and the motor 209 is fixedly connected inside the frame 101.

[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 motor 209 described in the above embodiment. For example, the motor 209 should be a motor with adjustable multi-speed. The purpose of this setting is to facilitate regulating the movement speed of the skateboard 201 in this way, thereby preventing the mortar from flowing out of the mold.

[0030] In the embodiment of the present utility model, relevant technicians place the mold in the groove of the slide plate 201, start grouting and simultaneously start the motor 209, so that the main shaft 207 fixedly connected to the center of the transmission gear 208 rotates synchronously, so that the main shaft 207 drives the eccentric wheel 203 fixedly connected thereto to start rotating, so that the push rod 202 rotatably connected to the eccentric part of the eccentric wheel 203 starts to perform circular motion, so that the push rod 202 starts to push the slide plate 201 hinged thereto, so that the slide plate 201 performs linear motion along its connection with the slide rod 206, so that the mold placed in the groove of the slide plate 201 starts to move synchronously, so that the mortar in it, under the action of inertia, is evenly filled into the mold, preventing the appearance of hollowing due to uneven mortar filling in some areas. At the same time, when the slide plate 201 moves, it synchronously pushes the rotating cylinder 204 to rotate, thereby reducing its frictional force and making the slide plate 201 move more quickly. At the same time, the rack 301 fixedly connected to the slide plate 201 moves synchronously during the movement of the slide plate 201, so that the rack 301 drives the gear 302 meshed with it to start rotating, so that the connecting rod 303 fixedly connected to the center of the gear 302 starts to rotate synchronously, so that the fan blade 304 fixedly connected to the top of the connecting rod 303 starts to rotate. By the rotation of the fan blade 304, the mortar falling on both sides of the slide plate 201 is pushed away, thereby preventing the mortar from flowing into the slide plate 201 through the gap between the mold and the slide plate 201, resulting in the inability to remove the mold after it solidifies.

[0031] 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 actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising 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.

[0032] 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.

[0033] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix the parts 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.

[0034] (2) Non-detachable connection: mainly refers to welding, riveting, and mortise fitting, etc. Since it needs to be forged, sawed, or oxy-cut to disassemble during maintenance or replacement, spare parts generally cannot be reused. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0035] The sliding connection referred to in this application means that a component can slide along a linear track, and the hinged connection referred to in this application means that a component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and the hinged connection referred to in this application can also be damped, so that the component has the ability to maintain at a desired position.

[0037] Although the embodiments of the present invention 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 principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
