Description

Technical Field

[0001] The invention relates to the field of vibration isolation devices, and in particular to a vibration isolation device for controlling vibration transmission. Background Art

[0002] Mechanical equipment will generate vibration and noise when it is in operation. Excessive vibration can cause damage to the equipment and can also cause the vibration to be transmitted to the ground or other equipment, thereby affecting the surrounding environment. The existing practice generally uses elastic support structures to reduce the system's ability to respond to external excitations, and replaces the rigid connection between the vibration source and the foundation with an elastic connection, which can isolate or weaken the transmission of vibration energy, thereby achieving the purpose of reducing vibration and noise;

[0003] The vibration isolation devices in the prior art are not convenient to be installed on mechanical equipment of different sizes during use, which makes installation and disassembly inconvenient, time-consuming and labor-intensive, and thus inconvenient to replace and install. In addition, when the vibration isolation devices in the prior art are not assembled on mechanical equipment, they are affected by the weight of the device itself, which can easily cause pressure on the internal vibration isolation springs, affecting the service life of the springs. Improvements are needed, and for this reason, we propose a vibration isolation device that controls vibration transmission. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a device that is easy to adapt to mechanical equipment of different sizes for installation; another purpose of the present invention is to provide a device that will not be affected by the weight of the device itself when not assembled on the mechanical equipment, thereby avoiding affecting the service life of the spring.

[0005] Technical solution: A vibration isolation device for controlling vibration transmission, comprising a base, and a supporting mechanism is symmetrically arranged above the base;

[0006] An elastic mechanism is provided between the two supporting mechanisms;

[0007] A clamping and mounting mechanism is commonly provided above the two supporting mechanisms;

[0008] A damper is symmetrically arranged between the clamping and mounting mechanism and the base;

[0009] The support mechanism includes two guide rails, the outer side wall of the guide rails is slidably connected with a slider, the upper surface of the slider is fixedly connected with a rotating connection member 1, the opposite sides of the two rotating connection members 1 opposite to each other are both rotatably connected to a support rod through a rotating shaft, one end of the support rod away from the rotating connection member 1 is rotatably connected to a rotating connection member 2 through a rotating shaft, and a cross bar is fixedly connected between the two sliders opposite to each other;

[0010] The elastic mechanism includes a box body, two sliding plates are slidably connected inside the box body, a plurality of elastic members are fixedly connected between the two sliding plates, a plurality of hydraulic boxes are fixedly connected to the opposite sides of the two sliding plates, a piston plate is slidably connected inside the hydraulic box, a side of the piston plate away from the sliding plate is fixedly connected to an abutment rod, an end of the abutment rod away from the piston plate penetrates to the outside of the box body, and a connecting box is slidably connected to the outer wall, a connecting box is fixedly connected to a connecting rod on the side of the connecting box away from the abutment rod, and an end of the connecting rod away from the box body is fixedly connected to a fixing sleeve;

[0011] A transfer box is fixedly connected to the upper surface of the box body, and a fluid exchange hose 1 is fixedly connected between the transfer box and the multiple hydraulic boxes. The top of the transfer box is fixedly connected to two fluid exchange tubes 2, and the top of the fluid exchange tubes 2 is fixedly connected to an elastic liquid bag.

[0012] Furthermore, the clamping and mounting mechanism includes a concave seat, the inner side of which is slidably connected to two clamping plates, the opposite sides of the two clamping plates are fixedly connected to two guide rods, the side of the guide rod away from the clamping plate passes through the outer side of the concave seat and is slidably connected to the concave seat, the opposite sides of the two clamping plates are rotatably connected to threaded rods via a rotating shaft, the left ends of the two threaded rods respectively pass through the two sides of the concave seat, and are both threadedly connected to the concave seat.

[0013] Furthermore, the bottom of the concave seat is fixedly connected to the top of the plurality of rotating connecting members 2.

[0014] Furthermore, a rubber pad is fixedly connected to the inner lower surface of the concave seat.

[0015] Furthermore, the opposite sides of the two elastic liquid bags are fixedly connected to the opposite sides of the two clamping plates respectively.

[0016] Furthermore, one end of the threaded rod away from the clamping plate is fixedly connected with a knob.

[0017] Furthermore, the top and the bottom of the damper are fixedly connected to the upper surfaces of the plurality of bases and the lower surface of the concave seat respectively.

[0018] Furthermore, the bottom of the guide rail is fixedly connected to the upper surface of the base.

[0019] Furthermore, the bottom of the box body is fixedly connected to the upper surface of the base, and the inner wall of the fixing sleeve is fixedly connected to the outer wall of the cross bar.

[0020] Beneficial effect: When the device is used, the mechanical equipment is placed inside the concave seat, and then the two threaded rods are respectively controlled to rotate by holding two knobs. Under the guidance of the guide rod, the clamping plate can be controlled to move relative to each other, and then the mechanical equipment can be clamped. This method enables the device to clamp mechanical equipment of different sizes;

[0021] After the clamping plate clamps the device, the elastic liquid bag will be squeezed, and liquid will be filled into the multiple hydraulic boxes at this time, so that the elastic member can play an elastic supporting role for the support rod, so that when the mechanical equipment starts to vibrate, it can play a vibration reduction effect on the mechanical equipment by cooperating with the vertically arranged damper to control the vibration transmission;

[0022] When no mechanical equipment is placed inside the concave seat and the clamping plate is not used to clamp the equipment, the elastic liquid bag will draw in liquid due to its own elastic effect. At this time, the abutment rod does not completely abut against the connecting box, so that the connecting box can slide along the abutment rod, thereby avoiding the elastic part from being squeezed. When the device is not installed on the mechanical equipment, the elastic part will not be affected by the weight of the device itself and squeezed, resulting in a deterioration of the elastic effect, affecting the vibration reduction effect during use.

DETAILED DESCRIPTION

[0029] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 3 As shown, a vibration isolation device for controlling vibration transmission is provided, comprising a base 1, and a supporting mechanism 2 is symmetrically arranged above the base 1;

[0032] The support mechanism 2 includes two guide rails 201, the outer wall of the guide rail 201 is slidably connected with a slider 202, the upper surface of the slider 202 is fixedly connected with a rotating connection member 1 203, the opposite sides of the two rotating connection members 1 203 opposite to each other are both rotatably connected with a support rod 204 through a rotating shaft, one end of the support rod 204 away from the rotating connection member 1 203 is rotatably connected with a rotating connection member 205 through a rotating shaft, and a cross bar 206 is fixedly connected between the two sliders 202 opposite to each other.

[0033] The bottom of the guide rail 201 is fixedly connected to the upper surface of the base 1;

[0034] To achieve a supporting effect, the slider 202 can slide along the outer side of the guide rail 201, and the inclination angle of the support rod 204 will change during the sliding.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an elastic mechanism 3 is provided between the two supporting mechanisms 2;

[0036] The elastic mechanism 3 includes a box body 301, two sliding plates 302 are slidably connected inside the box body 301, a plurality of elastic members 303 are fixedly connected between the two sliding plates 302, a plurality of hydraulic boxes 304 are fixedly connected to the opposite sides of the two sliding plates 302, a piston plate 305 is slidably connected inside the hydraulic box 304, a side of the piston plate 305 away from the sliding plate 302 is fixedly connected to an abutment rod 306, an end of the abutment rod 306 away from the piston plate 305 penetrates to the outside of the box body 301, and a connecting box 307 is slidably connected to the outer wall, a side of the connecting box 307 away from the abutment rod 306 is fixedly connected to a connecting rod 308, and an end of the connecting rod 308 away from the box body 301 is fixedly connected to a fixing sleeve 309;

[0037] The upper surface of the box body 301 is fixedly connected with a transfer box 310, and a first fluid changing hose 311 is fixedly connected between the transfer box 310 and the plurality of hydraulic boxes 304. The top of the transfer box 310 is fixedly connected with two second fluid changing tubes 312, and the top of the second fluid changing tubes 312 is fixedly connected with an elastic liquid bag 313;

[0038] The bottom of the box body 301 is fixedly connected to the upper surface of the base 1, and the inner wall of the fixing sleeve 309 is fixedly connected to the outer wall of the cross bar 206;

[0039] Liquid is stored between the elastic liquid capsule 313, the transfer box 310 and the plurality of hydraulic boxes 304. By squeezing the elastic liquid capsule 313 and the liquid, the piston plate 305 inside the hydraulic box 304 can be controlled to slide, so that the abutting rod 306 can abut against the inner side of the connecting box 307. At this time, the elastic member 303 can play a role of lateral elastic support for the supporting rod 204 and other components.

[0040] like Figure 1 and Figure 2 As shown, a clamping and mounting mechanism 4 is commonly provided above the two supporting mechanisms 2;

[0041] The clamping and mounting mechanism 4 includes a concave seat 401, the inner side of the concave seat 401 is slidably connected to two clamping plates 402, the opposite sides of the two clamping plates 402 are fixedly connected to two guide rods 403, the side of the guide rod 403 away from the clamping plate 402 penetrates to the outer side of the concave seat 401, and is slidably connected to the concave seat 401, the opposite sides of the two clamping plates 402 are rotatably connected to threaded rods 404 through rotating shafts, the left ends of the two threaded rods 404 respectively penetrate to the two sides of the concave seat 401, and are both threadedly connected to the concave seat 401;

[0042] The bottom of the concave seat 401 is fixedly connected to the top of the plurality of rotating connecting members 205;

[0043] A rubber pad 405 is fixedly connected to the inner lower surface of the concave seat 401;

[0044] The opposite sides of the two elastic liquid bags 313 are fixedly connected to the opposite sides of the two clamping plates 402 respectively.

[0045] One end of the threaded rod 404 away from the clamping plate 402 is fixedly connected with a knob 406;

[0046] A damper 5 is symmetrically arranged between the clamping and mounting mechanism 4 and the base 1;

[0047] The top and bottom of the damper 5 are fixedly connected to the upper surface of the plurality of bases 1 and the lower surface of the concave seat 401 respectively;

[0048] When the device is used, the mechanical device is placed inside the concave seat 401, and then the two threaded rods 404 are respectively controlled to rotate by holding the two knobs 406. Under the guidance of the guide rod 403, the clamping plate 402 can be controlled to move relative to each other, thereby facilitating the clamping of the mechanical device. This method enables the device to clamp mechanical devices of different sizes.

[0049] When the clamping plate 402 clamps the device, the elastic liquid capsule 313 will be squeezed, and liquid will be filled into the multiple hydraulic boxes 304, so that the elastic member 303 can play an elastic supporting role for the support rod 204, so that when the mechanical device starts to vibrate, the damper 5 arranged vertically can play a vibration reduction effect on the mechanical device to control the vibration transmission;

[0050] In addition, through the above-mentioned arrangement, no mechanical equipment is placed on the inner side of the concave seat 401. When the clamping plate 402 is not clamping the equipment for use, the elastic liquid capsule 313 will draw in liquid due to its own elastic effect. At this time, the abutment rod 306 does not completely abut the connecting box 307, so that the connecting box 307 can slide along the abutment rod 306, thereby preventing the elastic member 303 from being squeezed, and preventing the elastic member 303 from being squeezed due to the influence of the device's own weight when the device is not installed on the mechanical equipment, resulting in a deterioration of the elastic effect, thereby affecting the vibration reduction effect during use.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
