Description

Technical Field

[0001] This utility model relates to the field of concrete vibration technology, specifically a concrete vibration device. Background Technology

[0002] During concrete pouring, vibration is a crucial step in ensuring the density, strength, and durability of the concrete. Traditional concrete vibration methods mainly rely on manual operation of vibrators, which has many drawbacks.

[0003] First, manual vibration makes it difficult to ensure the uniformity and accuracy of vibration. Different operators have large differences in the control parameters such as vibration position, depth and time when vibrating concrete, which can easily lead to insufficient or excessive vibration in some areas, affecting the quality of concrete. Therefore, concrete vibration work is gradually being transformed from manual operation to automated vibration.

[0004] For example, Chinese invention patent application CN113323400A discloses a concrete vibration device and its usage method. Compared with the prior art, the concrete vibration device of the present invention eliminates the need for manual carrying of the vibration device and manual insertion of the vibration head into the concrete to be vibrated. It only requires manual start and stop of the vibration device, which does not require a lot of manpower, is very labor-friendly, and has high vibration efficiency.

[0005] However, currently, concrete vibrating devices need to be open at the top in order to enable concrete pumping equipment to pour concrete at the pouring location. There are no rainproof structures on the concrete vibrating devices. In rainy weather, rainwater may seep into the electrical components of the vibrating device, causing short circuits or malfunctions and causing construction to stop. The current conventional solution is to manually build temporary rain shelters, but this has problems such as low efficiency, poor flexibility, and insufficient coverage.

[0006] Based on this, the present invention designs a concrete vibration device to solve the above problems. Utility Model Content

[0007] This invention provides a concrete vibration device to solve the technical problem that existing concrete vibration devices do not have a rainproof structure.

[0008] According to one aspect of the present invention, a concrete vibration device is provided, comprising a support, a vibration unit disposed on the support for vibration, and a shielding unit disposed at the top of the support. The shielding unit includes a tarpaulin, a winding unit, and an unfolding unit. The winding unit and the unfolding unit are disposed on opposite sides of the top of the support. The winding unit is used to wind up the tarpaulin, and the unfolding unit is used to pull the tarpaulin out from the winding unit and unfold it above the vibration unit.

[0009] As a further embodiment of this utility model, the winding unit includes a first winding roller and a driving member. The first winding roller is rotatably mounted on the top of the bracket, and one end of the tarpaulin is fixed to the first winding roller. The driving member is mounted on the bracket to drive the first winding roller to rotate, so as to wind up or release the tarpaulin by rotating the first winding roller.

[0010] As a further embodiment of this utility model, the driving component includes a coil spring, which is mounted on a bracket. The two ends of the coil spring are respectively connected to the bracket and the first winding roller, and are used to drive the first winding roller to rotate in the direction of winding the tarpaulin.

[0011] As a further embodiment of this utility model, the driving component includes a first driving motor, which is mounted on the bracket and connected to the first take-up roller via an output shaft, for driving the first take-up roller to rotate.

[0012] As a further embodiment of this utility model, the bracket is provided with a mounting cover, and the driving component is disposed inside the mounting cover.

[0013] As a further embodiment of this utility model, the unfolding unit includes a traction rope connected to the end of the tarpaulin away from the winding unit and a winding rod provided on the bracket. The winding rod is installed horizontally at the top of the bracket. The end of the traction rope away from the tarpaulin passes over the winding rod from the top and hangs down. A counterweight is fixedly connected to the end of the traction rope away from the tarpaulin.

[0014] As a further embodiment of this utility model, the winding rod is a round rod.

The second winding roller is rotatably mounted on a support, and the support is provided with a second drive motor for driving the second winding roller to rotate. The end of the traction rope away from the tarpaulin is connected to the second winding roller. The second winding roller is used to wind the traction rope onto the second winding roller or release it from the second winding roller by rotating.

[0016] As a further embodiment of this utility model, the traction rope is provided in multiple forms, and the multiple traction ropes are evenly distributed at the end of the tarpaulin away from the winding unit.

[0017] As a further embodiment of this utility model, the winding unit and the unfolding unit have a height difference in the vertical direction, so that the unfolded tarpaulin is inclined to the horizontal plane.

[0018] This utility model has the following beneficial effects:

[0019] This device features a retractable unit, an unfolding unit, and a tarpaulin at the top of the support structure. The retractable unit retracts the tarpaulin completely when it is not raining, leaving the top of the support structure open and allowing the concrete pumping equipment to deliver concrete to the work area below. When it rains, the unfolding unit unfolds the tarpaulin to the top of the support structure, protecting the vibrating unit and the work area below from rain. This ensures the vibrating unit is not exposed to rain and that the concrete is not diluted by rainwater during heavy rain. Furthermore, concrete pouring and vibration operations can still be carried out during rain, reducing the impact of weather on concrete pouring and vibration operations.

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a concrete vibration device, including a support 1, a vibration unit 2 installed on the support 1 for vibration, and a shielding unit installed at the top of the support 1. The shielding unit can shield the vibration unit 2 when it rains, but the vibration operation can still be carried out by the vibration unit 2 when it rains. At the same time, the vibration unit 2 is protected to prevent rainwater from wetting the vibration unit 2 for a long time and causing damage to the vibration unit 2.

[0031] Specifically, the shielding unit includes a tarpaulin 3, a winding unit 4, and an unfolding unit 5. The winding unit 4 and the unfolding unit 5 are respectively located on opposite sides of the top of the support 1. The winding unit 4 is used to wind up the tarpaulin 3, and the unfolding unit 5 is used to pull the tarpaulin 3 out from the winding unit 4 and unfold it above the vibrating unit 2. When the tarpaulin 3 is in the wound state, the tarpaulin 3 is completely wound up on the winding unit 4, and the top of the support 1 is in an open state, so that concrete pumping equipment can be used normally for concrete pouring. When the tarpaulin 3 needs to be unfolded, the unfolding unit 5 pulls the tarpaulin 3 out from the winding unit 4. Since the winding unit 4 and the unfolding unit 5 are respectively located on opposite sides of the top of the support 1, the tarpaulin 3 is unfolded on the support 1 through the cooperation of the unfolding unit 5 and the winding unit 4, thereby achieving the shielding of the vibrating unit 2 on the support 1.

[0032] During operation, the entire device is erected in the work area. The vibrating device and the shielding unit are set up directly above the work area via the support 1. First, concrete is pumped into the work area by the concrete pumping equipment. Then, the vibrating unit 2 vibrates the areas where concrete has already been poured in the work area, realizing the concrete pouring and vibration operation. If it rains during the vibration process, the unfolding unit 5 pulls the rain cloth 3 out from the retracting unit 4, so that the rain cloth 3 is unfolded above the support 1. The rain cloth 3 shields the vibrating unit 2 below, preventing rainwater from contacting the vibrating unit 2 and protecting it. The unfolding degree of the rain cloth 3 can be precisely adjusted according to the position of the vibrating unit 2, so that the entire device can carry out vibration operation in rainy weather and cope with sudden weather changes.

[0033] Specifically, if there is light rain, when pouring concrete in the work area using the concrete pumping equipment, it is necessary to move from the side where the winding unit 4 is located to the side where the unfolding unit 5 is located. The vibration unit 2 follows closely behind to vibrate the concrete. When unfolding the tarpaulin 3 through the unfolding unit 5, the degree of unfolding of the tarpaulin 3 is controlled so that the tarpaulin 3 only covers the vibration unit 2. For the work area that has not yet been poured, the top is still open, and concrete can be pumped normally into the area by the concrete pumping equipment. The tarpaulin 3 always unfolds with the movement of the vibration unit 2, thereby realizing concrete pouring and vibration operations in light rain.

[0034] Specifically, in the event of heavy rain, the rainwater will dilute the concrete. Therefore, the tarpaulin 3 is fully deployed through the deployment unit 5 to cover the vibration unit 2 and the work area, preventing the vibration unit 2 from getting wet and preventing excessive rainwater from entering the work area. In this case, only a small concrete pump can be used to pour concrete in the work area by hand and the concrete is vibrated by the vibration unit 2, thus realizing concrete pouring and vibration operations in heavy rain.

[0035] Specifically, the winding unit 4 includes a first winding roller 41 and a driving member. The first winding roller 41 is rotatably mounted on the top of the bracket 1. One end of the tarpaulin 3 is fixed to the first winding roller 41. The driving member is mounted on the bracket 1 to drive the first winding roller 41 to rotate, so as to retract or release the tarpaulin 3 by rotating the first winding roller 41.

[0036] like Figure 2 As shown, the first take-up roller 41 is rotatably mounted on the top of the bracket 1, and the driving component is mounted on the bracket 1. The first take-up roller 41 is driven to rotate by the driving component. One end of the tarpaulin 3 is fixed on the first take-up roller 41. The tarpaulin 3 can be rolled up on the first take-up roller 41 by rotating the first take-up roller 41. When the tarpaulin 3 is unrolled, it needs to be released from the first take-up roller 41. When it is necessary to release the tarpaulin 3 from the first take-up roller 41, the first take-up roller 41 is rotated in the opposite direction to the rotation direction when the tarpaulin 3 is rolled up, so that the tarpaulin 3 can be released from the first take-up roller 41.

[0037] Figure 3 The first embodiment of the drive is shown. In this embodiment, the drive includes a coil spring 42, which is disposed on the bracket 1. The two ends of the coil spring 42 are respectively connected to the bracket 1 and the first take-up roller 41, and are used to drive the first take-up roller 41 to rotate in the direction of taking up the rain cloth 3.

[0038] like Figure 1 As shown, the top of the bracket 1 is provided with a mounting platform for mounting the coil spring 42 and the first take-up roller 41. The mounting platform is equipped with bearings. The two ends of the first take-up roller 41 are provided with rotating shafts, which are inserted into the bearings, thereby realizing the rotational mounting of the first take-up roller 41 on the bracket 1. The coil spring 42 is mounted on the mounting platform, with one end of the coil spring 42 connected to the mounting platform and the other end connected to the first take-up roller 41.

[0039] When the coil spring 42 is in its natural state, the tarpaulin 3 is completely rolled up on the first take-up roller 41. When the unfolding assembly pulls the tarpaulin 3 off the first take-up roller 41, the rotation of the first take-up roller 41 will cause the coil spring 42 to tighten or unfold, causing the coil spring 42 to undergo elastic deformation and have elastic potential energy. When the unfolding unit 5 no longer applies a pulling force to the tarpaulin 3 in a direction away from the first take-up roller 41, the elastic force of the coil spring 42 drives the first take-up roller 41 to rotate, causing the tarpaulin 3 to roll up onto the first take-up roller 41. When the tarpaulin 3 is released from the first take-up roller 41, the coil spring 42 stores energy. Finally, the elastic force of the coil spring 42 drives the first take-up roller 41 to rotate and retract the tarpaulin 3, thus realizing the release and retraction of the tarpaulin 3.

[0040] Figure 4 A second embodiment of the drive unit is shown. In this embodiment, the drive unit includes a first drive motor 43, which is mounted on the bracket 1 and connected to the first take-up roller 41 through an output shaft. The first drive motor 43 drives the first take-up roller 41 to rotate. The first drive motor 43 drives the first take-up roller 41 to rotate, and the tarpaulin 3 is rolled up and released according to the different rotation directions of the first take-up roller 41.

[0041] Specifically, the top of the bracket 1 is provided with a platform for mounting the first drive motor 43. The platform is located on the side of the mounting table away from the first take-up roller 41. The first drive motor 43 is mounted on the platform, and the output shaft of the first drive motor 43 is fixedly connected to and coaxially arranged with the first take-up roller 41. The first drive motor 43 drives the first take-up roller 41 to rotate, and the rotation direction of the first take-up roller 41 can be controlled. The tarpaulin 3 can be rolled up and released according to the different rotation directions of the first take-up roller 41.

[0042] Furthermore, the bracket 1 is provided with a mounting cover 44, and the driving component is located inside the mounting cover 44. The mounting cover 44 protects the driving component, preventing the coil spring 42 or the first drive motor 43 from being exposed to wind and rain, thereby extending the service life of the coil spring 42 or the first drive motor 43.

[0043] Figure 4 The first embodiment of the unfolding unit 5 is shown. In this example, the unfolding unit 5 includes a traction rope 51 connected to the end of the tarpaulin 3 away from the winding unit 4 and a winding rod 52 provided on the bracket 1. The winding rod 52 is installed laterally at the top of the bracket 1. The end of the traction rope 51 away from the tarpaulin 3 passes over the winding rod 52 from the top and hangs down. The end of the traction rope 51 away from the tarpaulin 3 is fixedly connected to a counterweight 53.

[0044] Specifically, the winding rod 52 is mounted on the bracket 1, and is located at the top of the bracket 1 away from the first take-up roller 41. One end of the traction rope 51 is fixed to the free end of the tarpaulin 3, and the other end hangs down from the top of the winding rod 52. A counterweight 53 is also installed at the end of the traction rope 51 away from the tarpaulin 3. The weight of the counterweight 53 is applied to the free end of the tarpaulin 3 through the traction rope 51, ensuring that the free end of the tarpaulin 3 always has a pulling force that moves away from the first take-up roller 41. Therefore, in this example, the driving component needs to be a first drive motor 43. The first drive motor 43 drives the first take-up roller 41 to release the tarpaulin 3, and the counterweight 53... The tarpaulin 3 can be pulled towards the winding rod 52 by the traction rope 51. The counterweight 53 will descend as the tarpaulin 3 is released, keeping the tarpaulin 3 in a flat state. When the tarpaulin 3 needs to be retracted, the first drive motor 43 only needs to drive the first take-up roller 41 to retract the tarpaulin 3. The counterweight 53 will rise as the tarpaulin 3 is rolled up. The weight of the counterweight 53 is applied to the free end of the tarpaulin 3, so that the tarpaulin 3 always receives a pulling force towards the winding rod 52. At this time, the first drive motor 43 can drive the first take-up roller 41 to rotate to realize the winding or unfolding of the tarpaulin 3. The winding and unfolding of the tarpaulin 3 are controlled separately by the first drive motor 43, making it simpler to use.

[0045] Furthermore, the winding rod 52 is a round rod. When the tarpaulin 3 is rolled up and released, the traction rope 51 will slide on the winding rod 52. When the winding rod 52 is a round rod, the contact position between the traction rope 51 and the winding rod 52 can be evenly stressed, preventing stress concentration, reducing the wear of the traction rope 51, and improving the service life of the traction rope 51.

[0046] Figure 2 A second example of the unfolding unit 5 is shown. In this example, the unfolding unit 5 includes a traction rope 51 connected to the end of the tarpaulin 3 away from the winding unit 4 and a second winding roller 54 for winding the traction rope 51. The second winding roller 54 is rotatably mounted on the bracket 1, and the bracket 1 is provided with a second drive motor 55 for driving the second winding roller 54 to rotate. The end of the traction rope 51 away from the tarpaulin 3 is connected to the second winding roller 54. The second winding roller 54 is used to wind the traction rope 51 onto the second winding roller 54 or release it from the second winding roller 54 by rotation.

[0047] Specifically, such as Figure 2 As shown, the second drive motor 55 drives the second take-up roller 54 to rotate. The rotation of the second take-up roller 54 can either wind the traction rope 51 onto the second take-up roller 54 or release it from the second take-up roller 54, which correspond to the release of the tarpaulin 3 and the winding of the tarpaulin 3, respectively. In this example, the driving component can be a coil spring 42 or a first drive motor 43.

[0048] When the driving component uses a coil spring 42, the second drive motor 55 drives the second take-up roller 54 to rotate. Depending on the rotation direction of the second take-up roller 54, the traction rope 51 is wound and released on the second take-up roller 54. When the traction rope 51 is wound onto the second take-up roller 54, the traction rope 51 pulls the tarpaulin 3 off the first take-up roller 41. The tarpaulin 3 drives the first take-up roller 41 to rotate, thereby completing the energy storage of the coil spring 42. When the second take-up roller 54 releases the traction rope 51, the coil spring 42 drives the first take-up roller 41 to rotate and wind the tarpaulin 3 onto the first take-up roller 41, thereby realizing the release and winding of the tarpaulin 3. In this example, the winding and releasing of the tarpaulin 3 is controlled separately by the second drive motor 55, making the use and control of the overall device simpler.

[0049] When the driving component uses the first driving motor 43, the first driving motor 43 and the second driving motor 55 jointly control the winding and unfolding of the tarpaulin 3. Since the winding linear speed of the tarpaulin 3 is constantly changing when it is winding, it is necessary to precisely control the speed of the first driving motor 43 and the second driving motor 55, making the structure more complex. However, it can achieve rapid unfolding and winding of the tarpaulin 3 to cope with emergencies.

[0050] Furthermore, such as Figure 2 As shown, there are multiple traction ropes 51, which are evenly distributed at the end of the tarpaulin 3 away from the winding unit 4 to ensure that the free end of the tarpaulin 3 remains flat and to improve the rainproof effect of the tarpaulin 3 after it is unfolded.

[0051] Furthermore, such as Figure 1 As shown, there is a height difference between the winding unit 4 and the unfolding unit 5 in the vertical direction, so that the unfolded tarpaulin 3 is inclined to the horizontal plane. After rainwater drips onto the tarpaulin 3, it will slide off the tarpaulin 3 along the inclined direction of the tarpaulin 3 under the action of gravity, preventing rainwater from accumulating on the tarpaulin 3 and ensuring the safe use of the tarpaulin 3.

[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
