Description

Technical Field

[0001] The utility model relates to the technical field of equipment installation, in particular to a suspension type equipment installation frame for noise reduction and vibration reduction. Background Art

[0002] Commercial places such as supermarkets and large shopping malls are usually equipped with central air conditioning or fresh air systems to control the indoor air or temperature accordingly; central air conditioning or fresh air systems are usually equipped with air pumps as the power of air circulation; when the air pump is started, it will generate noise and vibration, affecting the customer's shopping experience. Usually, these devices are directly installed on the floor slab, and the shock-absorbing structure of the leg part is used to reduce shock; therefore, the floor slab needs to have a certain structural strength; however, the bottom floor slab where the equipment is installed in some commercial places is too thin to support the operation of the equipment; therefore, a suspended equipment mounting frame is selected for equipment installation. However, the current suspended equipment mounting frame lacks noise reduction and shock absorption structure, and cannot reduce the noise and vibration of the equipment, affecting people's lives and work. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and provide a suspension equipment mounting frame for noise reduction and vibration reduction.

[0004] The technical solution of the utility model is: a suspension equipment installation frame for noise reduction and shock absorption, which is arranged between the upper floor and the bottom floor, and includes a support frame, a plurality of hoisting round steels, a thick rubber pad, a spring shock absorber, a pad steel plate, a nut, a limit channel steel and a limit steel plate;

[0005] Several hoisting round steels are evenly distributed along the edge of the support frame to ensure uniform hoisting of the support frame; the upper end of the hoisting round steel passes through the upper floor slab, thick rubber pad, and iron plate in sequence and is threadedly connected with the nut, thereby ensuring a stable connection between the upper end of the hoisting round steel and the upper floor slab; the thick rubber pad is tightly attached to the upper floor slab, and the iron plate is tightly attached to the thick rubber pad; the lower end of the nut is against the top surface of the iron plate; the lower end of each hoisting round steel is connected to the support frame through a spring shock absorber; the spring shock absorber provides vertical shock absorption to the support frame;

[0006] A vertical limiting steel plate extends horizontally outward from the outer side surface of the edge of the support frame; two limiting steel plates form a group; the limiting channel steel is vertically installed on the bottom floor slab; the upper end of the limiting channel steel is vertically inserted between each group of limiting steel plates; the side surface of the limiting channel steel and the inner side surface of the limiting steel plate cooperate with the limiting channel steel to horizontally limit each group of limiting steel plates, thereby avoiding horizontal shaking of the support frame.

[0007] Preferably, the spring shock absorber and the limit channel steel are symmetrically arranged relative to the support frame, so that the vertical limit and shock absorption effect provided by the spring shock absorber and the horizontal limit provided by the limit channel steel can be evenly applied to the support frame, so that the support frame can obtain better vertical noise reduction and shock absorption and horizontal noise reduction and shock absorption effects.

[0008] Preferably, the support frame is a channel steel welded frame; channel steel is a common profile and is easy to use.

[0009] Preferably, the thick rubber pad includes a square rubber pad and a cylindrical rubber sleeve. The square rubber pad abuts against the pad iron steel plate, and a through hole matching the upper end of the hoisting round steel is provided in the middle position. The square rubber pad and the pad iron steel plate can smoothly transmit force. The rubber sleeve is inserted into the upper floor slab. The upper end of the hoisting round steel passes through the rubber sleeve and the through hole. The length of the rubber sleeve is ≤ the thickness of the floor slab. The rubber sleeve can separate the upper floor slab and the hoisting round steel, thereby reducing the collision between the hoisting round steel and the upper floor slab and ensuring the hoisting stability of the support frame.

[0010] Preferably, the square rubber pad, the iron plate and the nut are symmetrically arranged up and down about the upper floor slab, which can enhance the hoisting stability of the hoisting round steel to the support frame. The symmetrical design of the upper and lower nuts can provide a certain pre-tightening force for the device.

[0011] Preferably, a base is provided at the bottom of the limit channel steel, and the limit channel steel is fixedly connected to the lower floor slab through the base. The base can expand the contact area between the limit channel steel and the lower floor slab, so as to ensure the stability of the limit channel steel when it is vertically erected.

[0012] Furthermore, the base is a horizontal bottom plate; both ends of the bottom plate are connected to the bottom floor plate through expansion bolts; the use of expansion bolts for installation is very convenient, and the structural strength requirements for the bottom floor plate are not high.

[0013] Preferably, the diameter of the hoisting round steel is greater than or equal to the diameter of the through hole of the thick rubber pad. The hoisting round steel and the through hole are interference fit, which can limit the swing of the hoisting round steel.

[0014] Preferably, a rubber pad is provided on the inner side of the limit steel plate; the side of the limit channel steel is in close contact with the rubber pad. The rubber pad can further limit the horizontal position of the support frame to ensure that the horizontal position of the support frame remains unchanged, and can also play a buffering role for the horizontal shaking of the support frame.

[0015] The beneficial effects of the utility model are as follows: the suspended equipment mounting frame for noise reduction and shock absorption of the present application can withstand a large weight, and the spring shock absorber is connected to the bottom of the lifting round steel and then connected to the support frame. The array of spring shock absorbers can absorb the vibration of the equipment in the vertical direction and provide a better shock absorption effect. After each lifting round steel passes through the floor, a pad steel plate with a certain area is used to disperse the weight; a number of groups of limiting steel plates are evenly distributed on the outer side of the edge of the support frame, and a vertical limiting channel steel is correspondingly installed on the bottom floor; two limiting steel plates are grouped together, and the upper end of each limiting channel steel is inserted between each group of limiting steel plates; the space between the limiting channel steel and the limiting steel plate is filled with rubber material, which plays a certain buffering role; the overall swing of the support frame in the horizontal direction can be limited, and the separate design can ensure that the bottom floor will not be under pressure.

[0028] Several hoisting round steel bars 2 are evenly distributed along the edge of the support frame 1 to ensure uniform hoisting of the support frame 1; the upper end of the hoisting round steel bar 2 passes through the upper floor slab 01, the thick rubber pad 3, the pad iron steel plate 4 in sequence and is threadedly connected with the nut, thereby determining a stable connection relationship between the upper end of the hoisting round steel bar 2 and the upper floor slab 01; the thick rubber pad 3 is tightly attached to the upper floor slab 01, and the pad iron steel plate 4 is tightly attached to the thick rubber pad 3; the lower end of the nut is against the top surface of the pad iron steel plate 4; the lower end of each hoisting round steel bar 2 is connected to the support frame 1 through the spring 51 shock absorber 5; the spring 51 shock absorber 5 provides vertical shock absorbing effect to the support frame 1;

[0029] A vertical limiting steel plate 11 extends horizontally outward from the outer side surface of the edge of the support frame 1; two limiting steel plates 11 form a group; the limiting channel steel 6 is vertically installed on the bottom floor slab 02; the upper end of the limiting channel steel 6 is vertically inserted between each group of limiting steel plates 11; the side surface of the limiting channel steel 6 cooperates with the inner side surface of the limiting steel plate 11; the limiting channel steel 6 horizontally limits each group of limiting steel plates 11, which can avoid horizontal shaking of the support frame 1.

[0030] Compared with the prior art, the utility model suspends the support frame 1 with the hoisting round steels 2 evenly distributed along the edge of the support frame 1; each hoisting round steel 2 shares the main load of the support frame 1 to the upper floor 01 through the thick rubber pad 3 at the upper end of the hoisting round steel 2, so that the bottom floor 02 is less loaded or even unloaded; the limiting channel steel 6 limits the support frame 1 horizontally to achieve the effect of noise reduction and shock absorption in the horizontal direction; the spring 51 shock absorber 5 reduces noise and shock absorption in the vertical direction of the support frame 1; the limiting channel steel 6 is combined with the spring 51 shock absorber 5 to finally achieve noise reduction and shock absorption of the suspended equipment 03 mounting frame.

[0031] There are various types of spring 51 shock absorbers 5, which are no longer listed one by one in this embodiment; the spring 51 shock absorber 5 used in this embodiment includes a spring 51, a pressure plate 52, a vertically arranged guide column 53 and a shell 54; the lower end of the lifting round steel 2 is threadedly matched with the upper end of the guide column 53; the lower end of the guide column 53 passes through the top of the shell 54 and is inserted into the inside of the shell 54; a disc is installed at the lower end of the guide column 53; the spring 51 is sleeved on the outside of the guide column 53, the upper end is connected to the shell 54, and the lower end is connected to the pressure plate 52; the bottom of the shell 54 is threadedly matched with a connecting rod 7; the connecting rod 7 is threadedly connected to the support frame 1; after the connecting rod 7 passes through the plane of the bracket, it is threadedly matched with a lifting nut.

[0032] In this embodiment, the shell 54 is an upper shell and a lower shell that are buckled together; the upper shell and the lower shell are connected by bolts and nuts; a cavity is formed between the upper shell and the lower shell; the hoisting round steel 2 passes through the upper shell; the upper end of the connecting rod 7 is threadedly connected to the lower shell; the spring 51 and the pressure plate 52 are arranged in the cavity; the upper end of the spring 51 is connected to the upper shell.

[0033] The spring 51 shock absorber 5 and the limiting channel steel 6 are symmetrically arranged relative to the support frame 1, and can evenly apply the vertical limiting and shock absorbing effect provided by the spring 51 shock absorber 5 and the horizontal limiting effect provided by the limiting channel steel 6 to the support frame 1, so that the support frame 1 can obtain better vertical noise reduction and shock absorption and horizontal noise reduction and shock absorption effects.

[0034] The support frame 1 is a channel steel welded frame; channel steel is a common profile and is easy to use.

[0035] The thick rubber pad 3 includes a square rubber pad 31 and a cylindrical rubber sleeve 32. The square rubber pad 31 abuts against the pad iron steel plate 4, and a through hole matching the upper end of the hoisting round steel 2 is set in the middle position; the square rubber pad 31 and the pad iron steel plate 4 can smoothly transmit force; the rubber sleeve 32 is inserted into the upper floor 01; the upper end of the hoisting round steel 2 passes through the rubber sleeve 32 and the through hole; the length of the rubber sleeve 32 is ≤ the floor thickness.

[0036] The square rubber pad 31, the pad steel plate 4, and the nut are symmetrically arranged about the upper floor 01, which can enhance the hoisting stability of the hoisting round steel 2 to the support frame 1. The symmetrical design of the upper and lower nuts can provide a certain pre-tightening force for the device.

[0037] The bottom of the limiting channel steel 6 is provided with a base 61, and the limiting channel steel 6 is fixedly connected to the lower floor through the base 61.

[0039] The diameter of the hoisting round steel 2 is greater than or equal to the diameter of the through hole of the thick rubber pad 3. The hoisting round steel 2 and the through hole are interference fit, which can limit the swing of the hoisting round steel 2.
