Description

Technical Field

[0001] The invention relates to the technical field of elevator shaft sound insulation, in particular to a construction engineering elevator shaft soundproofing structure. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. Most of the existing home elevators do not have a good quiet effect, which makes it easy for the elevator to generate loud noise during operation, thus affecting the rest of other family members. The reason for the noise generated by the elevator is generally the wind noise generated when the elevator is running and the mechanical noise generated by the equipment in the elevator shaft. The second noise is that the elevator moves in the track for a long time, and the friction between the track and the elevator increases, which generates vibration noise and friction noise. As for wind noise and Mechanical noise is usually reduced by installing a sound insulation board in the elevator shaft. However, during the installation of the sound insulation board, workers are required to set up the keel and then connect it with tools such as screws to complete the installation of the sound insulation board. However, due to the high height of the elevator shaft, the efficiency of the sound insulation board is low during the multi-step installation, and there are many operating steps, which affects the installation efficiency of the equipment. For friction noise, manual oiling is required frequently to reduce the noise. This operation also invisibly increases the workload of the workers and requires timely oiling. If the oiling cannot be done in time, the noise will become louder, thus affecting the use of the equipment.

At the same time, the sound insulation of the interior can be effectively guaranteed in conjunction with the silent board mechanism, and the indirect work of the lubrication mechanism can effectively replace manual lubrication, making it more convenient and practical at work.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 8 , the present invention provides a technical solution:

[0030] A silent structure for an elevator shaft in a construction project, comprising a shaft body 1, wherein both left and right sides of the shaft body 1 are fixedly connected with a concrete precast plate 2, a rear side of the shaft body 1 is fixedly connected with a concrete precast track 3, a filling sponge 4 is filled between the concrete precast plate 2 and the inner wall of the shaft body 1, a sound insulation plate mechanism 5 is arranged in the concrete precast plate 2, and a plurality of connection mechanisms 13 are arranged between the sound insulation plate mechanism 5 and the concrete precast plate 2, a traction machine 22 is arranged in the shaft body 1, an elevator 23 is fixedly connected to the traction machine 22, the elevator 23 is slidably connected in the concrete precast track 3, a transmission gear 24 is rotatably connected to the traction machine 22, a transmission mechanism 25 is arranged in the shaft body 1, the transmission mechanism 25 and the transmission gear 24 are meshed with each other, a lubrication mechanism 30 is arranged in the shaft body 1, the transmission mechanism 25 and the lubrication mechanism 30 are movably connected, and the lubrication mechanism 30 is located on the upper side of the concrete precast track 3;

[0031] When working, firstly, the precast concrete panel 2 and the precast concrete track 3 are precast on the side of the well body 1 through the precast concrete, and at the same time, the connecting mechanism 13 is fixed in the precast concrete panel 2 when the equipment is precast. After the precast concrete panel 2 and the precast concrete track 3 are precast, the sound insulation board mechanism 5 is installed, so that the equipment is more convenient to install and the drilling process of the equipment is reduced. The precast concrete panel 2 and the precast concrete track 3 are more stable than the installed materials during production, and form an integrated structure at the same time. When the sound insulation board mechanism 5 is installed, the first splicing plate 6 is first installed, so that the first splicing plate 6 is connected through the first plug-in mechanism 8 and the connecting mechanism 13. Connected with the concrete precast panel 2, at this time, only the first splicing plate 6 needs to be squeezed to complete the installation of the first splicing plate 6, and then the second splicing plate 7 is spliced ​​with the first splicing plate 6. At the same time, during the splicing process, the second splicing plate 7 is connected to the concrete precast panel 2, and the sound insulation board mechanism 5 can be installed by gradually connecting them in sequence. The gradual installation of the parts inside the sound insulation board mechanism 5 reduces the installation steps, and only simple splicing is needed to install it, so that the equipment is more efficient during installation and more stable during installation. The sound insulation board mechanism 5 can effectively absorb the wind noise in the well body 1 and the noise generated by the operation of the elevator 23, and then improve the quietness in the well body 1;

[0032] When the sound insulation board mechanism 5 is installed, the sound insulation board mechanism 5 is used to soundproof the interior thereof. Meanwhile, when the traction machine 22 drives the elevator 23 to work, the repeated operation of the traction machine 22 can simultaneously control the transmission mechanism 25 to work. When the transmission mechanism 25 works, the parts inside the transmission mechanism 25 gradually rotate. When the traction machine 22 moves to a certain number of circles, the transmission mechanism 25 squeezes the lubrication mechanism 30, so that the liquid inside the lubrication mechanism 30 enters the precast concrete track 3, thereby reducing the friction between the elevator 23 and the precast concrete track 3 when the elevator 23 is running, making it more lubricated when working, thereby reducing the noise of the elevator 23 from the source. Meanwhile, the sound insulation inside the elevator 23 can be effectively guaranteed by cooperating with the soundproof board mechanism, and the indirect operation of the lubrication mechanism 30 can effectively replace the lubrication by manpower, making it more convenient and practical when working.

[0033] As a further solution of the present invention, the sound insulation board mechanism 5 includes a first splicing plate 6, a second splicing plate 7, a first plug-in mechanism 8 and a second plug-in mechanism 12. A plurality of first splicing plates 6 and a plurality of second splicing plates 7 are movably connected in the concrete precast panel 2. The first splicing plate 6 and the second splicing plate 7 are movably spliced. A plurality of connecting holes are provided on the rear sides of the first splicing plate 6 and the second splicing plate 7. The connecting mechanism 13 is movably plugged into the connecting hole. A first plug-in mechanism 8 is provided between the first splicing plate 6 and the second splicing plate 7 and the concrete precast panel 2, and a second plug-in mechanism 12 is provided between the first splicing plate 6 and the second splicing plate 7.

[0034] During operation, the first splicing plate 6 is connected to the precast concrete plate 2. At this time, the first plug-in mechanism 8 and the connecting mechanism 13 can effectively install the first splicing plate 6 in the precast concrete plate 2. Then the second splicing plate 7 and the first splicing plate 6 are spliced, and the second plug-in mechanism 12 can effectively splice the second splicing plate 7 and the first splicing plate 6. This is repeated, which can effectively improve the installation efficiency of the sound insulation board mechanism 5.

[0035] As a further solution of the present invention, a placement groove is provided on the precast concrete panel 2, the sound insulation panel mechanism 5 is located in the placement groove, the first splicing panel 6 and the second splicing panel 7 both include a honeycomb panel, sound-absorbing cotton, a filling layer, a gypsum board and a keel, the keel is provided with a gypsum board, the gypsum board is provided with a filling layer, the outer side of the filling layer is provided with a sound-absorbing cotton layer, and the outer side of the sound-absorbing cotton layer is provided with a honeycomb panel;

[0036] When working, the honeycomb panel can effectively absorb the noise at the first level. At the same time, it cooperates with the filling layer and sound-absorbing cotton to fully absorb the noise, avoid the overflow of noise, and further improve the sound insulation effect of the equipment.

[0037] As a further solution of the present invention, the first plug-in mechanism 8 and the second plug-in mechanism 12 have the same structure. The first plug-in mechanism 8 includes a first spring 9, a plug-in rod 10 and a plug-in hole 11. A plurality of first springs 9 are fixedly connected in the first splicing plate 6. One end of the first spring 9 is fixedly connected to the plug-in rod 10. One end of the plug-in rod 10 is changed into an arc shape. A plurality of plug-in holes 11 are opened on the precast concrete plate 2. The plug-in rod 10 is movably connected in the plug-in hole 11. The plug-in hole 11 in the second plug-in mechanism 12 is located on the second splicing plate 7. The plug-in rod 10 in the second plug-in mechanism 12 is located on the first splicing plate 6.

[0038] During operation, when the first splicing plate 6 and the second splicing plate are close to the precast concrete plate 2, the precast concrete plate 2 squeezes the plug rod 10, causing the plug rod 10 to squeeze the first spring 9. At this time, the first spring 9 is compressed, and the plug rod 10 shrinks into the first splicing plate 6. When the first splicing plate 6 moves to a suitable position, the elastic force of the first spring 9 squeezes the plug rod 10, causing the plug rod 10 to be inserted into the plug hole 11, thereby keeping the first splicing plate 6 fixed, making the equipment more convenient to install and reducing manual operation steps.

[0039] As a further solution of the present invention, the connecting mechanism 13 includes a fixed column 14, a mounting column 15, a card plate 16, a slide 17, a second spring 18, a slider 19, a receiving groove 20 and a pull rod 21. A plurality of fixed columns 14 are fixedly connected to the precast concrete panel 2, the fixed column 14 is fixedly connected to the mounting column 15, the mounting column 15 is rotatably connected to the card plate 16, the mounting column 15 is truncated, the card plate 16 is provided with a slide 17, the slide 17 is fixedly connected to the second spring 18, the slide 17 is slidably connected to the slider 19, one end of the second spring 18 is fixedly connected to the slider 19, the mounting column 15 is provided with a receiving groove 20, and a pull rod 21 is provided between the slider 19 and the receiving groove 20;

[0040] During operation, when the first splicing plate 6 and the second splicing plate 7 are installed, as the first splicing plate 6 moves, the connecting hole on the first splicing plate 6 and the card plate 16 are movably connected. At this time, the connecting hole squeezes the card plate 16, causing the card plate 16 to rotate into the storage groove 20, and the second spring 18 is compressed at the same time. When the card plate 16 completely enters the connecting hole, the elastic force of the second spring 18 squeezes the slider 19 and controls the pull rod 21 to open, thereby making the card plate 16 in a dispersed state, and then the card plate 16 forms a resistance, maintaining the connection between the first splicing plate 6 and the concrete precast panel 2, making it more stable, more convenient and quicker to install.

[0041] As a further solution of the present invention, the transmission mechanism 25 includes a speed regulating box 26, a one-way wheel 27, a rotating rod 28 and a cam 29. The speed regulating box 26 is installed in the well body 1, and the one-way wheel 27 is installed on the speed regulating box 26. The one-way wheel 27 and the transmission gear 24 are movably engaged with each other. A rotating rod 28 is rotatably connected in the well body 1, and the rotating rod 28 is transmission-connected to the speed regulating box 26. A damping layer is provided on one side of the rotating rod 28, and a cam 29 is installed on the rotating rod 28. The cam 29 is movably connected to the lubrication mechanism 30;

[0042] During operation, when the traction machine 22 is working, the traction machine 22 drives the transmission gear 24 to work. When the transmission gear 24 is working, the transmission gear 24 is divided into two reverse rotations. When the elevator 23 moves up, the one-way wheel 27 does not rotate. When the elevator 23 moves down, the transmission gear 24 drives the one-way wheel 27 to rotate. Each time the transmission gear 24 drives the one-way wheel 27 to rotate, the one-way wheel 27 drives the cam 29 to rotate a certain angle. When the traction machine 22 rotates to a certain number of circles, the cam 29 squeezes the lubrication mechanism 30, so that the lubrication mechanism 30 produces lubricating fluid, thereby lubricating the concrete prefabricated track, thereby performing intermittent lubrication, thereby reducing the friction between the track and the elevator 23, and then making the equipment more quiet when working.

[0043] As a further solution of the present invention, the lubrication mechanism 30 includes a liquid storage tank 31, a pump 32, a liquid control mechanism 33 and a nozzle 34. The liquid storage tank 31 is installed in the well body 1, and the pump 32 is provided on the liquid storage tank 31. The liquid control mechanism 33 is provided on the upper side of the precast concrete track 3, and the liquid control mechanism 33 and the pump 32 are connected through. Two nozzles 34 are provided on the upper side of the precast concrete track 3, and the nozzles 34 and the liquid control mechanism 33 are connected through.

[0044] When working, the pump 32 transports the liquid in the liquid storage tank 31 to the control mechanism, so that the equipment can perform quantitative lubrication during lubrication, avoiding waste of lubricating liquid, and at the same time reducing the noise of the equipment from the source, making the equipment more effective when in use. When the liquid control mechanism 33 discharges the liquid, the liquid enters the concrete precast track 3 through the nozzle 34, and then completes the lubrication.

[0045] As a further solution of the present invention, the liquid control mechanism 33 includes a fixed tube 35, a pressure rod 36, a third spring 37, a through hole 38, a liquid storage tank 39 and a drip hole 40. The fixed tube 35 is fixedly connected to the upper side of the precast concrete track 3, and the pressure rod 36 is slidably connected in the fixed tube 35. The pressure rod 36 and the transmission mechanism 25 are movably connected. A third spring 37 is provided between the pressure rod 36 and the fixed tube 35. A through hole 38 is provided on the pressure rod 36. A liquid storage tank 39 is provided in the fixed tube 35. Connecting tubes 41 are provided on the fixed tube 35 and the pressure rod 36, wherein two connecting tubes 41 are connected to the nozzle 34, and another connecting tube 41 is connected to the pump 32.

[0046] During operation, when the cam 29 rotates to a certain position, the cam 29 squeezes the pressure rod 36, causing the pressure rod 36 to descend. When the pressure rod 36 descends, the through hole 38 opened on the pressure rod 36 is connected with the liquid storage tank 39, so that the liquid in the pressure rod 36 enters the liquid storage tank 39. At this time, the liquid is discharged through the drip hole 40 and the connecting pipe 41, so that the nozzle 34 transports the liquid to the concrete precast track 3, and then completes the lubrication of the track, thereby effectively reducing the noise when the equipment is in use.
