Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, specifically to a concrete compaction device for the top layer of rail transit. Background Technology

[0002] In rail transit engineering, the density of the top-layer concrete directly affects the load-bearing capacity and durability of the track structure. To ensure the compaction of large-area concrete surfaces, continuous vibration using a vibrator is usually required. However, current construction methods largely rely on manual operation with a handheld vibrator, requiring operators to move across large concrete surfaces and maintain a vibrating posture for extended periods. This method has significant drawbacks: firstly, it is labor-intensive, easily leading to arm and back muscle fatigue and affecting the health of construction workers; secondly, it is inefficient, requiring repeated shifts in position, making it difficult to ensure continuous and uniform vibration; and thirdly, the vibration quality is affected by human factors, easily resulting in under-vibration or over-vibration.

[0037] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions of this invention are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0039] like Figure 1-4As shown in the figure, this embodiment of the invention proposes a concrete compaction device for the top layer of rail transit, comprising: a support frame 10, a lifting seat 20 slidably disposed thereon, and mounting grooves 21 are provided on both sides of the lifting seat 20; a mounting seat 30 slidably disposed on the lifting seat 20 and mounted with a vibrator; a moving mechanism, including a sliding seat 40 slidably disposed on the mounting groove 21 and connected to both sides of the mounting seat 30, and a driving member 50 disposed on the lifting seat 20, the driving member 50 being connected to the sliding seat 40 for driving the mounting seat 30 to reciprocate along the extension direction of the mounting groove 21; and a lifting assembly 60 connected to the lifting seat 20 for controlling its lifting.

[0040] Specifically, in use, the support frame 10 is first placed across the concrete area, and the vibrator is installed on the mounting base 30, suspending the vibrator between the lifting base 20 and the concrete construction area. Then, the vibrating working part of the vibrator is placed into the concrete using the lifting assembly 60, and then the vibrator is started to vibrate the concrete construction area. Because the vibrator is installed through the mounting base 30, it not only bears the overall weight of the vibrator and part of the vibration generated during operation, but also eliminates the need for long-term manual handling, saving manpower, and indirectly improving the stability of the vibration posture during concrete processing.

[0041] Secondly, the lifting seat 20 is connected to the mounting base 30 carrying the vibrator via a moving mechanism. Specifically, the drive component 50 in the moving mechanism is installed on the lifting seat 20, and then the slide 40 in the moving mechanism is connected to the drive component 50 and slidably engaged in the mounting grooves 21 on both sides of the lifting seat 20, so that the slide 40 can slide along the length of the mounting groove 21, thereby changing the position of the vibrator on the lifting seat 20.

[0042] During operation, the drive unit 50 drives the slide 40, which in turn drives the mounting base 30 to reciprocate along the length of the mounting groove 21. This allows the mounting base 30 to automatically reciprocate the vibrator above the concrete processing area, eliminating the need for manual adjustment of the vibrator's position and achieving automated large-area vibration operations. Simultaneously, the lifting assembly 60 allows adjustment of the height of the lifting base 20 according to the thickness of the concrete layer, ensuring that the vibrator is inserted into the concrete to a suitable and consistent depth.

[0043] In addition, the bottom of the support frame 10 is equipped with casters 70. After the moving mechanism drives the vibrator to complete the vibration of a certain working surface, the support frame 10 can be pushed and the casters 70 can be used to move the construction work surface along the long axis, thereby shortening the construction period.

[0044] In addition, pulley sets 41 are provided on both the upper and lower sides of the slide 40, and the pulley sets 41 are rolledly connected to the inner side of the mounting groove 21. The pulley sets 41 directly contact the inner wall of the mounting groove 21. When the slide 40 moves, the pulley sets 41 roll along the mounting groove 21. By setting the pulley sets 41, the sliding friction of the slide 40 is changed to rolling friction during movement, thereby effectively reducing running resistance, achieving smooth reciprocating motion of the mounting base 30, reducing energy loss and component wear, and simultaneously reducing operating noise.

[0045] Specifically, such as Figure 2-3 As shown, in this embodiment of the invention, the driving component 50 includes: a fixed block 51 disposed on the slide 40 and having a driving groove 52; two sprockets 53, with a first fixed frame 54 on one side of the lifting seat 20, wherein one of the sprockets 53 is rotatably disposed on the first fixed frame 54; a first driver 56, with a second fixed frame 55 on the other side of the lifting seat 20, the first driver 56 being disposed on the second fixed frame 55 and connected to the other sprocket 53; and a chain 57, which is driven between the two sprockets 53 and has a driving pin 58, the driving pin 58 being slidably disposed in the driving groove 52. During operation, when the first driver 56 is started, its output shaft drives the sprocket 53 connected to it to rotate. Through the transmission action of the chain 57, the other sprocket 53 rotates synchronously, causing the chain 57 to make a circular motion between the two sprockets 53. Simultaneously, the driving pin 58 fixedly disposed on the chain 57 moves along with the chain 57. Since the drive pin 58 is also embedded in the drive groove 52 of the fixed block 51, and the fixed block 51 is fixedly connected to the slide 40, when the drive pin 58 moves with the chain 57, the drive pin 58 will slide relative to the drive groove 52 and exert a thrust on the side wall of the drive groove 52, thereby pushing the fixed block 51 together with the slide 40 to move along the length direction of the mounting groove 21.

[0046] As the chain 57 continues to rotate, when the drive pin 58 moves to the end of the sprocket 53, it changes direction and enters the other side of the drive groove 52, thus pushing the fixed block 51 and the slide 40 in the opposite direction. This cycle repeats, with the drive pin 58 rotating in a circular motion driven by the chain 57, while the drive groove 52 converts the horizontal component of the circular motion into the linear reciprocating motion of the slide 40. By controlling the forward and reverse rotation of the first driver 56 or by using continuous unidirectional rotation, the slide 40 can achieve stable reciprocating movement within the mounting groove 21, thereby driving the mounting base 30 and the vibrator to uniformly vibrate a large area of ​​concrete.

[0047] Furthermore, the drive pin 58 is provided with a rotating shaft, and the drive pin 58 is rotatably mounted on the chain 57 via the rotating shaft. By mounting the drive pin 58 on the chain 57 via the rotating shaft, the drive pin 58 can rotate freely around the rotating shaft. When the drive pin 58 enters the drive groove 52 and slides relative to it, the rotating shaft allows the drive pin 58 to automatically fine-tune its angle according to the direction of force, thereby smoothly rolling or sliding in the drive groove 52, greatly reducing sliding friction, extending the service life of the drive pin 58 and the drive groove 52, and reducing the energy consumption of the first driver 56. The first driver 56 can be any one of a servo motor or an electric motor.

[0048] It is worth noting that, in this embodiment of the invention, the chain drive 57 is a closed or semi-closed drive, which has a high tolerance for harsh working conditions such as dust and moisture commonly encountered in concrete construction. Even if a small amount of dust or mud enters the transmission parts, it is not likely to cause slippage or transmission failure. Compared with belt drives or open gear drives, it has higher reliability and is very suitable for construction site environments. Of course, to further ensure long-term operational stability, in actual use, protective shells can also be added to the transmission parts (such as sprocket 53, chain 57, and first drive 56) to prevent large particles of impurities from entering. The installation method of this protective shell adopts conventional technical means (such as bolt fixing or snap-fit ​​connection), which will not be described in detail here.

[0049] Specifically, such as Figure 1 As shown, in this embodiment of the invention, the lifting assembly 60 includes two take-up wheels 61 rotatably mounted on the support frame 10, a suspension rope 62 wound around the take-up wheels 61, and a second driver 63 mounted on the support frame 10. The two take-up wheels 61 are connected by a transmission rod 64, the suspension rope 62 is connected to the lifting seat 20, and the output shaft of the second driver 63 is connected to one of the take-up wheels 61. During operation, when it is necessary to adjust the insertion depth of the vibrator or to lift the vibrator as a whole, the second driver 63 is activated. The output shaft of the second driver 63 drives one of the take-up wheels 61 connected to it to rotate. Since the two take-up wheels 61 are connected by the transmission rod 64, the other take-up wheel 61 rotates synchronously. With the two winding wheels 61 winding or releasing the lifting rope 62 simultaneously, since the lower end of the lifting rope 62 is fixedly connected to the lifting seat 20, the lifting seat 20 is driven to move up and down along the support frame 10. Then, by controlling the forward and reverse rotation of the second drive 63, the lifting seat 20 can be raised or lowered, thereby controlling the depth of the vibrator inserted into the concrete.

[0050] In this embodiment of the invention, the second driver 63 can be a manually operated self-locking mechanism (e.g., a hand-cranked winch with ratchet self-locking). The operator adjusts the lifting platform 20 by hand, and the self-locking mechanism automatically locks the position after adjustment, preventing the lifting platform 20 from sliding down due to gravity and thus avoiding limitations imposed by factors such as construction site, environment, and manpower. Preferably, in this embodiment of the invention, the second driver 63 is either a servo motor or an electric motor.

[0051] Furthermore, the support frame 10 is provided with a sliding groove 11, and the lifting seat 20 is provided with a slider 12, which is slidably engaged with the sliding groove 11. When the lifting assembly 60 drives the lifting seat 20 to move up and down, the slider 12 slides along the sliding groove 11, thereby ensuring that the lifting seat 20 remains vertical and stable when moving up and down, avoiding swaying back and forth or left and right, thus ensuring that the angle at which the vibrator is inserted into the concrete is always correct and improving the vibration quality.

[0052] Specifically, such as Figure 4 As shown in this embodiment of the invention, the mounting base 30 has an arc-shaped latch 31, and the vibrator is elastically secured to the mounting base 30 by the arc-shaped latch 31. Specifically, the arc-shaped latch 31 is used to engage the non-vibrating part of the vibrator, preventing vibration from being directly transmitted to the mounting base 30. Simultaneously, because the arc-shaped latch 31 has a certain degree of elasticity, it can generate an elastic clamping force according to the diameter of the vibrator, ensuring that it does not move relative to the vibrator after being fixed, and also facilitating installation and disassembly. In practical use, the non-vibrating part of the vibrator is aligned with the arc-shaped latch 31 of the mounting base 30, and by slightly pressing or inserting it, it is tightly embedded in the latch, thereby fixing the vibrator. When it is necessary to replace or clean the vibrator, it can be directly removed from the arc-shaped latch 31 or reinstalled without additional tools, making the operation very convenient.

[0053] In addition, the inner wall of the arc-shaped bayonet 31 is detachably equipped with an elastic pad. Installing the elastic pad between the arc-shaped bayonet 31 and the vibrator can buffer the contact pressure between the vibrator and the bayonet, reducing scratches or indentations on the surface of the vibrator, while increasing friction and further improving clamping stability. Furthermore, the elastic pad is detachable for easy replacement.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
