Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, specifically a noise-reducing building construction platform. Background Technology

[0002] During construction, operations such as metal component cutting, stone grinding, and steel bar processing generate high-frequency, high-decibel industrial noise. This noise not only exceeds the prescribed limits but also causes acoustic interference to sensitive areas such as surrounding residential areas, schools, and hospitals, leading to complaints from neighbors. To alleviate construction noise problems, a frame structure combined with sound insulation panels is used to build a four-sided enclosed work platform, placing high-noise equipment in a noise-reducing space for operation.

[0003] Currently, noise reduction panels on the four sides of a work platform are typically fixed to a frame, with multiple movable entrances and exits on the sides of the enclosed space. However, these entrances and exits are independently controlled and have small openings, which can easily obstruct the entry and exit of large equipment or long materials. Furthermore, if equipment or materials collide with the rigid noise reduction panels during transfer, the lack of an elastic buffer structure can cause damage to both the noise reduction panels and the materials being transported. Therefore, a noise-reducing construction platform is needed to address the problems existing in current technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a noise-reducing construction platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing construction platform, comprising a support platform, with a noise-reducing frame for construction noise reduction enclosure installed above the support platform. The noise-reducing frame includes an upright support and a noise-reducing plate that flips and unfolds therewith. The upright support is fixed to the edge of the support platform's tabletop. A cross support is installed above the support platform, with an adjustment threaded groove at the center of the upper end face of the cross support. A threaded rotating rod is threadedly connected inside the adjustment threaded groove, and a lifting mechanism for supporting the noise-reducing plate and keeping it flipped is fixed at the lower end of the threaded rotating rod.

[0006] Preferably, a horizontal support is fixed between adjacent upright supports, and the four ends of the cross support are all fixed to the four horizontal supports.

[0007] Preferably, a flipping shaft is fixed to the upper part of both ends of the noise reduction plate, and a rotating groove is provided on both sides of the upright bracket, with the flipping shaft rotatably connected inside the rotating groove.

[0008] Preferably, the lifting mechanism includes a cross sleeve, which is fixed to the lower end of the threaded rotating rod. A telescopic slide is slidably connected inside the cross sleeve, and a guide wheel is rotatably connected to one end of the telescopic slide.

[0009] Preferably, a telescopic slider is fixed at one end of the telescopic carriage that extends into the cross sleeve, and the telescopic slider is slidably connected in the sliding cavity of the cross sleeve.

[0010] Preferably, a return spring is fitted at the part of the telescopic slide that extends into the cross sleeve. One end of the return spring is fixed to the end face of the telescopic slide block, and the other end of the return spring is fixed to the inner end wall of the cross sleeve.

[0011] Preferably, the upright support has a receiving opening at one corner, and the cross sleeve is located below the cross support.

[0012] Preferably, the noise reduction board is either a glass wool board or a rock wool board.

[0013] This utility model provides a noise-reducing construction platform, which has the following advantages compared with the prior art:

[0014] With the noise reduction frame and the flipping mechanism, when the flipping mechanism is perpendicular to the four noise reduction plates, the supporting action of the flipping mechanism drives the four noise reduction plates to flip synchronously in the rotating slot of the upright support through the flipping shaft. The flipping of the four noise reduction plates on the support platform opens the inlet and outlet, which facilitates the transfer of equipment and materials. Furthermore, the synchronous opening and closing action of the four noise reduction plates makes the switching of the opening and closing state relatively quick.

[0015] With the addition of a flip-plate mechanism, once the flip-plate mechanism is rotated and adjusted, the support for the guide wheel is removed from the upright bracket. The telescopic slide can automatically extend outward under the return force of the return spring, expanding the support length range of the flip-plate mechanism. Thus, without the need for manual adjustment of the support span, the noise reduction plate can be stably supported from the inside to maintain a large-angle flip. This not only meets the needs of large equipment and long materials for entry and exit, but also allows the return spring to absorb some of the impact force if materials or equipment accidentally collide with the noise reduction plate during transport, reducing the risk of mutual damage caused by collisions between the noise reduction plate and materials or equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This utility model provides a noise-reducing construction platform, including a support platform 1. A noise-reducing frame 2 for construction noise reduction enclosure is installed above the support platform 1. The noise-reducing frame 2 includes an upright support 12 and a noise-reducing plate 14 that flips and unfolds therewith. A horizontal support 13 is fixed between the upright support 12 and the horizontal support 13 on each side. The four ends of the cross support 3 are fixed to the four horizontal supports 13. A flipping shaft 16 is fixed to the upper part of both end faces of the noise-reducing plate 14. Rotation grooves 15 are provided on both side walls of the upright support 12. The flipping shaft 16 is rotatably connected inside the rotating groove 15. The erecting bracket 12 is fixed to the edge of the support platform 1. A cross bracket 3 is provided above the support platform 1. An adjustment threaded groove 11 is provided at the center of the upper end face of the cross bracket 3. A threaded rotating rod 4 is threadedly connected inside the adjustment threaded groove 11. Before the cutting equipment and materials enter or exit, the handle of the threaded rotating rod 4 is turned by hand, which drives the threaded rotating rod 4 to rotate downward along the adjustment threaded groove 11 of the cross bracket 3. This allows the height of the lifting mechanism 5 to be lowered and the angle to be switched.

[0026] It is worth noting that the lower end of the threaded rotating rod 4 is fixed with a lifting mechanism 5 for supporting the noise reduction plate 14 to maintain its rotation. The lifting mechanism 5 includes a cross sleeve 6, which is fixed to the lower end of the threaded rotating rod 4. A telescopic slide 7 is slidably connected inside the cross sleeve 6, and a guide wheel 8 is rotatably connected to one end of the telescopic slide 7. When the lifting mechanism 5 is perpendicular to the four noise reduction plates 14, since the span of the lifting mechanism 5 is greater than the distance between the four noise reduction plates 14, the supporting effect of the lifting mechanism 5 drives the four noise reduction plates 14 to rotate synchronously in the rotating groove 15 of the upright bracket 12 through the rotating shaft 16. The way in which the four noise reduction plates 14 rotate on the support platform 1 to open the inlet and outlet facilitates the transfer of equipment and materials, and the synchronous opening and closing action of the four noise reduction plates 14 makes the switching of the opening and closing state relatively quick.

[0027] It is worth noting that a telescopic slider 9 is fixed to one end of the telescopic slide 7 that extends into the cross sleeve 6. The telescopic slider 9 is slidably connected in the sliding cavity of the cross sleeve 6. A return spring 10 is fitted on the part of the telescopic slide 7 that extends into the cross sleeve 6. One end of the return spring 10 is fixed to the end face of the telescopic slider 9, and the other end of the return spring 10 is fixed to the inner end wall of the cross sleeve 6. A receiving opening 17 is provided at one corner of the erecting bracket 12. The cross sleeve 6 is located below the cross bracket 3. After the lifting mechanism 5 is rotated to the adjusted position, the support bracket 12 is lifted to remove the support for the guide wheel 8. In this way, the telescopic slide 7 automatically extends outward under the rebound force of the return spring 10 and expands the support length range of the lifting mechanism 5, so that it supports the noise reduction plate 14 from the inside and keeps it flipped at a large angle to open the access port. In addition, the four noise reduction plates 14 have a certain buffering effect under the elastic support of the lifting mechanism 5, so as to reduce the risk of mutual damage caused by collision between the materials and equipment and the noise reduction plates 14 when they are transported in and out.

[0028] It is worth noting that the noise reduction board 14 is either a glass wool board or a rock wool board.

[0029] This solution involves the following process: During the cutting operation of workpieces in construction, personnel can transfer the materials to be processed and the cutting equipment to the support platform 1 for noisy cutting. A noise reduction frame 2 surrounds the support platform 1, forming a noise-reducing construction space. The noise reduction board 14 is either glass wool board or rock wool board, and has numerous tiny interconnected pores inside. Sound waves can penetrate deep into the material along these pores, and through friction with the material, convert sound energy into heat energy, thus achieving the effect of sound absorption and noise reduction.

[0030] Before the cutting equipment and materials enter and exit, the handle of the threaded rotating rod 4 is turned by hand, which drives the threaded rotating rod 4 to rotate downward along the adjustment thread groove 11 of the cross bracket 3. This allows for the adjustment of the height and switching angle of the lifting mechanism 5. When the lifting mechanism 5 is perpendicular to the four noise reduction plates 14, since the span of the lifting mechanism 5 is greater than the distance between the four noise reduction plates 14, the supporting effect of the lifting mechanism 5 drives the four noise reduction plates 14 to rotate synchronously in the rotating groove 15 of the upright bracket 12 through the flipping shaft 16. The way in which the four noise reduction plates 14 flip on the support platform 1 to open the inlet and outlet facilitates the transfer of equipment and materials. Furthermore, the synchronous opening and closing action of the four noise reduction plates 14 makes the switching of the opening and closing state relatively quick.

[0031] Similarly, when the lifting mechanism 5 rotates into the noise reduction space and is positioned and supported in the upright bracket 12, the four noise reduction plates 14 naturally droop under the action of gravity, and are finally positioned under the action of magnets to achieve the formation of the noise reduction space enclosure.

[0032] When the four noise reduction panels 14 are in the noise reduction space, they are magnetically attracted and positioned by the magnetic blocks at the bottom and the magnetic blocks inside the support platform 1. Before rotating the lifting mechanism 5, one end of the guide wheel 8 in the lifting mechanism 5 is supported at the receiving port 17 of the upright bracket 12. At the same time, the telescopic slide 7 is retracted into the cross sleeve 6 so that the return spring 10 is kept in a stretched deformation state. After the lifting mechanism 5 is rotated to adjust the position, the upright bracket 12 is no longer supported by the guide wheel 8. In this way, the telescopic slide 7 automatically expands outward under the rebound force of the return spring 10 and expands the support length range of the lifting mechanism 5, so as to support the noise reduction panel 14 from the inside and keep it flipped at a large angle to open the access port. In addition, the four noise reduction panels 14 have a certain buffering effect under the elastic support of the lifting mechanism 5, so as to reduce the risk of mutual damage caused by collision between the materials and equipment when they are transported in and out.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
