Description

Technical Field

[0001] This utility model relates to the field of track slab production technology, specifically to a pneumatic lifting and vibrating platform for track slab production. Background Technology

[0002] With the continuous advancement and development of rail transit technology, the design and manufacturing of track slabs will also continue to innovate and optimize. In the future, track slabs may place greater emphasis on improving performance in areas such as lightweighting, high strength, and durability to meet the demands of rail transit with higher speeds, greater loads, and harsher environments.

[0003] Concrete vibration is a key process in the production of track slabs, and the vibration effect directly affects the quality of track slab products. In the production process of track slab assembly lines, the vibration platform structure commonly used in track slab production involves connecting the upper steel plate and the bottom support beam with rubber bearings. This results in problems such as low vibration transmission efficiency, short service life, difficult maintenance, and serious noise, which affect product quality and increase production and operating costs.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

[0005] To address the aforementioned technical deficiencies, the present invention provides a pneumatic lifting and vibrating platform for track slab production, comprising a support frame, rollers, and a support plate. The upper end of the support frame is equipped with an industrial airbag and rollers. The industrial airbag is connected to an external air source. The rollers are connected via a transmission assembly to transport the vibrating mold. The support plate is fixedly mounted on the upper end of the industrial airbag. The support plate has a clearance groove corresponding to the rollers, and the rollers are positioned within the clearance groove. A vibrating motor is mounted at the bottom of the support plate, and the vibrating mold is positioned above the support plate.

[0006] Preferably, each of the support frames is provided with a track support beam on its exterior, and adjacent support frames or support frames and transport tracks are connected by the track support beam.

[0007] Preferably, the industrial airbag is provided with a vent, and the vent is provided with a vent valve to control the opening and closing of the vent.

[0008] Preferably, the transmission assembly includes a transmission motor, a first roller, and a second roller. The transmission motor is fixedly mounted on the support frame, and the first roller is fixedly mounted on the transmission shaft of the transmission motor. The second roller is fixedly sleeved on the roller conveyor, and a belt drives the second roller and the first roller together.

[0009] Preferably, a plurality of the rollers are symmetrically arranged on both sides of the support frame, the support plate is configured as a rectangular plate, and the two sides of the support plate are provided with the clearance grooves corresponding to the rollers.

[0010] Preferably, a stabilizing bar is fixedly provided on the upper part of the support frame, and a plurality of the stabilizing bars are arranged in a straight line along the transport direction of the vibrating mold, and the extension direction of the stabilizing bars is perpendicular to the transport direction of the vibrating mold, with the two ends of the stabilizing bars located on both sides of the support frame.

[0011] Preferably, the upper surface of the support plate is provided with longitudinal limiting posts, which are symmetrically arranged on both sides of the support plate. The longitudinal limiting posts on one side of the support plate are arranged in a straight line along the transport direction of the vibrating mold. When the industrial airbag is deflated, the longitudinal limiting posts are arranged on both sides of the vibrating mold.

[0012] Preferably, the upper surface of the support plate is further provided with transverse limiting posts, which are located at both ends of the support plate. When the industrial airbag is deflated, the upper edge of the transverse limiting posts is lower than the top of the roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By adopting a pneumatic lifting structure, this utility model has higher vibration transmission efficiency and less energy loss during the vibration process compared with traditional vibrating platforms. This allows concrete to be vibrated and molded faster, improving production efficiency and extending service life. The service life of traditional vibrating platforms is about 3 years. After modification according to the content of this utility model, the service life will be more than doubled. The noise is also low. The noise near the operation of traditional vibrating platforms can reach 100 decibels. After modification according to the content of this utility model, the noise can be reduced to below 50 decibels. 2. Through the design of the support plate, this utility model allows the industrial airbag to start inflating, which drives the support plate to rise. The rise of the support plate can drive the vibrating mold to move upward, realizing the switching between horizontal transportation and vertical operation of the vibrating mold.

Detailed Implementation

[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, Figure 1 This is a schematic diagram of the pneumatic lifting and vibrating platform used for track slab production. Figure 2 This is a schematic diagram of the pneumatic lifting and vibrating platform used for track slab production.

[0024] Figure 3 This is a structural view of the support frame; Figure 4 for Figure 3 A magnified view of the structure at point A in the middle; Figure 5 This is a structural view of the bottom of the support plate.

[0025] The pneumatic lifting and vibrating platform for track slab production of this utility model includes a support frame 1, roller wheels 5, and a support plate 9. The upper end of the support frame 1 is provided with an industrial airbag 2 and roller wheels 5. The industrial airbag 2 is connected to an external air source to control the inflation and deflation of the industrial airbag 2. The roller wheels 5 are connected through a transmission assembly to achieve rotation around their own axis to transport the vibrating mold 13. The support plate 9 is fixedly provided above the industrial airbag 2. The support plate 9 is provided with a clearance groove 18 corresponding to the roller wheels 5. The roller wheels 5 are located in the clearance groove 18. The bottom of the support plate 9 is provided with a vibrating motor 10. The vibrating mold 13 is located above the support plate 9.

[0026] Generally, the industrial airbag 2 is configured as an airbag structure with internal guiding components, such as an air spring, in the prior art, to ensure that the industrial airbag 2 can be directionally inflated and supported in the vertical direction.

[0027] A bracket 11 is fixedly installed in the middle of both sides inside the support frame 1, and a base frame 12 is fixedly installed above the bracket 11. The bracket 11 and the base frame 12 are used to strengthen the overall structural strength of the support frame 1.

[0028] Generally, each of the support frames 1 is provided with a track support beam 4 on its exterior. Adjacent support frames 1 or support frames 1 and transport track are connected by the track support beam 4. After the vibrating mold 13 performs a vibration operation at the current work station, it can be moved to the corresponding work station of the next support frame 1 or transported to the next work station via the transport track, thereby switching between different work stations.

[0029] Preferably, the industrial airbag 2 is provided with a vent 17, through which the gas inside the industrial airbag 2 can be quickly released. The vent 17 is provided with a vent valve to control the opening and closing of the vent 17.

[0030] Specifically, the transmission assembly includes a transmission motor 8, a first roller 14, and a second roller 16. The transmission motor 8 is fixedly mounted on the support frame 1. The first roller 14 is fixedly mounted on the transmission shaft of the transmission motor 8. The second roller 16 is fixedly sleeved on the roller wheel 5. A belt 15 is drivingly connected between the second roller 16 and the first roller 14. Thus, the transmission motor 8 can drive the roller wheel 5 to rotate, thereby realizing the track transportation of the vibrating mold 13 placed on the roller wheel 5.

[0031] When the operator uses the equipment, they first place the vibrating mold 13 above the roller wheel 5. Then, they fix one end of the external air source to the industrial airbag 2 and start the external air source. When the external air source is started, air is injected into the industrial airbag 2, causing it to expand upward under the action of the guide component. This pushes the support plate 9 upward, and as the support plate 9 moves upward, it comes into contact with the vibrating mold 13, causing the vibrating mold 13 to gradually separate from the roller wheel 5. When the air pressure inside the industrial airbag 2 reaches the rated value, the external air source can be turned off, and then the vibrating motor 10 is turned on to start the concrete pouring and vibration operation. When the work is completed, the vent valve is opened, and all the industrial airbags 2 begin to release air. The vibrating mold 13 then descends and finally falls above the roller wheel 5 before being transported to the next work station.

[0032] This invention, employing a pneumatic lifting structure, offers higher vibration transmission efficiency and less energy loss compared to traditional vibratory platforms. This allows for faster concrete compaction and shaping, improving production efficiency and extending service life. Traditional vibratory platforms have a lifespan of approximately 3 years; after modification according to this invention, the lifespan will more than double. Furthermore, noise levels are significantly reduced; traditional vibratory platforms generate up to 100 decibels of noise during operation, while modifications according to this invention reduce the noise level to below 50 decibels.

[0033] Example 2

[0034] Several rollers 5 are symmetrically arranged on both sides of the support frame 1. The support plate 9 is a rectangular plate-shaped component. Both sides of the support plate 9 are provided with clearance grooves 18 corresponding to the rollers 5, thereby allowing the rollers 5 to stably support and transport the vibrating mold 13. When the industrial airbag 2 deflates, the top of the roller 5 can extend beyond the upper surface of the support plate 9 through the clearance grooves 18 to contact and support the bottom of the vibrating mold 13, ensuring that the rollers 5 and the support plate 9 do not interfere with each other during transport of the vibrating mold 13. Generally, the industrial airbag 2 is located on both sides of the rollers 5 to stably support the support plate.

[0035] The design of the vibrating motor 10 enables the support plate 9 to vibrate after it is started, thereby causing the vibrating mold 13 to vibrate.

[0036] Preferably, a stabilizing bar 6 is fixedly installed on the upper part of the support frame 1. Several stabilizing bars 6 are arranged in a straight line along the transport direction of the vibrating mold 13, and the extension direction of the stabilizing bars 6 is perpendicular to the transport direction of the vibrating mold 13. The two ends of the stabilizing bars 6 are located on both sides of the support frame 1. When the industrial airbag 2 deflates, the bottom of the support plate 9 is stably supported by the stabilizing bars 6, avoiding long-term heavy pressure on the industrial airbag 2 and ensuring the initial stability of the support plate 9.

[0037] The upper surface of the support plate 9 is provided with longitudinal limiting posts 7. The longitudinal limiting posts 7 are symmetrically arranged on both sides of the support plate 9, and each of the longitudinal limiting posts 7 on one side of the support plate 9 is arranged in a straight line along the transport direction of the vibrating mold 13. When the industrial airbag 2 is deflated, the longitudinal limiting posts 7 are arranged on both sides of the vibrating mold 13.

[0038] The upper surface of the support plate 9 is also provided with a transverse limiting post 3. The transverse limiting post 3 is located at both ends of the support plate 9. When the industrial airbag 2 is deflated, the upper edge of the transverse limiting post 3 is lower than the top of the roller wheel 5.

[0039] When the industrial airbag 2 is deflated, the longitudinal limiting posts 7 on both sides of the vibrating mold 13 play an auxiliary guiding role during the linear transmission of the vibrating mold 13. The upper edge of the transverse limiting post 3 is slightly lower than the top of the roller wheel 5, thereby avoiding interference between the transverse limiting post 3 and the vibrating mold 13 during the linear transmission of the vibrating mold 13.

[0040] When the industrial airbag 2 is inflated, the bottom of the vibrating mold 13 is completely placed on the support plate 9. The longitudinal limiting post 7 limits the two sides of the vibrating mold 13, and the transverse limiting post 3 limits the two ends of the vibrating mold 13, thereby ensuring the relative position between the vibrating mold 13 and the support plate 9 is stable.

[0041] The support frame 1 has five rollers 5 on one side, which are evenly distributed inside the support frame 1. The design of the rollers 5 allows them to rotate and move the mold.

[0042] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
