[0003] Comparing with Chinese Patent Publication No. CN 210011554 U, a generator set caster device is disclosed, including rubber casters. Support side plates are symmetrically installed on both sides of the rubber casters. A main support plate is connected to the upper end of each support side plate. A foot brake body is installed on one side of the upper end of each support side plate, above the rubber caster. A connecting plate is connected to the upper end of the main support plate. A shock-absorbing device is connected to the upper end of the connecting plate. A fixing plate is installed at the front end of the foot brake body. Mounting side plates are fixedly connected to both sides of the fixing plate. Mounting holes are opened at the front end of each mounting side plate. Support side plate insertion holes are opened at the upper part of the lower end of each mounting side plate. A foot brake plate is rotatably mounted at the lower end of the fixing plate through the support side plate insertion holes. Fixing teeth are evenly and symmetrically installed at the bottom end of the foot brake plate. This invention provides excellent shock absorption during use.

[0004] The disadvantages of the above-mentioned patent are: it can only buffer vertical vibrations, while horizontal swaying will reduce the service life of the shock absorption device; when the amplitude is large, it cannot guarantee a good shock absorption effect, and the shock absorption body is compressed to the limit stroke in a short time, directly transmitting the vibration to the casters, generating resonance and causing damage to the precision components inside the unit. Utility Model Content

[0005] The purpose of this invention is to provide a generator set caster shock absorption and stabilization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A generator set caster shock absorption and stabilization device includes a shock-absorbing component for suppressing resonance, a stabilizing component for improving the smoothness of buffered movement above the shock-absorbing component, a load-bearing component for supporting the generator and preventing dust from entering the device on the top of the stabilizing component, and an energy-absorbing component that uses elastic deformation to prolong the impact force application time between the shock-absorbing component and the stabilizing component; the energy-absorbing component includes a covering layer, and a plurality of hollow tubes are disposed inside the covering layer, with the hollow tubes bonded to the covering layer.

[0008] Preferably, the shock absorption assembly includes a connecting seat, a hydraulic buffer column is installed at the bottom of the connecting seat, a spring is sleeved on the hydraulic buffer column, a support plate is provided at the top of the hydraulic buffer column, a dust cover is provided at the top of the connecting seat, a limit groove is formed in the inner wall of the connecting seat, and a caster connection hole is formed on the bottom surface of the connecting seat.

[0009] Preferably, the stabilizing component includes a connecting block, which is symmetrical on all four sides and has at least eight supports, with two rubber wheels rotatably mounted on each support.

[0010] Preferably, the supporting component includes a fixed platform, a material collection trough is provided around the fixed platform, a cleaning port is provided on one side of the material collection trough, a rubber pad is provided on the top surface of the fixed platform, and an assembly mounting hole is provided on the fixed platform through the rubber pad.

[0014] Preferably, the top of the connecting block is bolted to the fixing platform.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this utility model, the connecting block drives the rubber wheel to slide up and down along the limiting groove, reducing the friction between the connecting block and the connecting seat. The elastic deformation of the rubber wheel absorbs horizontal vibration, making the shock absorption effect better and improving the stability of the unit.

[0017] In this utility model, by bonding a large number of hollow tubes together to form a mesh structure, the elastic deformation is used to extend the impact time, dissipate vibration energy, and prevent the hydraulic buffer column and spring from being compressed to the limit stroke in a short time, thus extending their service life.

[0018] In this invention, diesel fuel and debris in the collection trough are collected from the cleaning port to prevent them from entering the connecting seat and to ensure the cleanliness of the internal parts. Attached Figure Description

[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 Figures 1-4 A generator set caster shock absorption and stabilization device includes a shock absorption component 1 for suppressing resonance, a stabilization component 2 for improving the smoothness of buffer movement above the shock absorption component 1, a load-bearing component 3 for supporting the generator and blocking dust entry device on the top of the stabilization component 2, and an energy-absorbing component 4 for extending the impact force action time by utilizing elastic deformation between the shock absorption component 1 and the stabilization component 2.

[0026] In this embodiment: the shock absorption component 1 includes a connecting seat 101, a hydraulic buffer column 102 is installed at the bottom of the connecting seat 101, a spring 104 is sleeved on the hydraulic buffer column 102, a support plate 103 is provided at the top of the hydraulic buffer column 102, a dust cover 105 is provided at the top of the connecting seat 101, a limit groove 106 is opened on the inner wall of the connecting seat 101, and a caster connection hole 107 is opened on the bottom surface of the connecting seat 101. The caster is connected to the bottom of the connecting seat 101 through the caster connection hole 107. The vertical vibration of the connecting block 201 is buffered by the elastic force generated by the compression of the spring 104 and the resistance of the oil flow inside the hydraulic buffer column 102.

[0027] In this embodiment: the stabilizing component 2 includes a connecting block 201. The connecting block 201 is symmetrical on four sides and has at least eight supports 202. Two rubber wheels 203 are rotatably mounted on the supports 202. The rubber wheels 203 are placed in the limiting groove 106, and the limiting groove 106 extends longitudinally. When the generator is working or the casters move, vibration is generated. The vibration is transmitted to the connecting block 201 through the fixed platform 301. The vertical vibration drives the connecting block 201 to rise and fall. The supports 202 drive the rubber wheels 203 to move up and down along the limiting groove 106.

[0028] In this embodiment: the supporting component 3 includes a fixed platform 301, a material collection trough 302 is provided around the fixed platform 301, a cleaning port 303 is provided on one side of the material collection trough 302, a rubber pad 304 is provided on the top surface of the fixed platform 301, and a generator mounting hole 305 is provided through the rubber pad 304 on the fixed platform 301. The top of the connecting block 201 is bolted to the fixed platform 301. The generator set is installed on the fixed platform 301 through the generator mounting hole 305 and the rubber pad 304. After the generator is turned off, the diesel fuel and debris in the material collection trough 302 are collected from the cleaning port 303.

[0029] In this embodiment, the energy-absorbing component 4 includes a covering layer 401, and a plurality of hollow tubes 402 are disposed inside the covering layer 401. The hollow tubes 402 are bonded to each other with the covering layer 401. The hollow tubes 402 are arranged in multiple layers with adjacent layers intersecting. The cross-sectional shape of the hollow tubes 402 is either circular or elliptical. The bottom surface of the covering layer 401 is attached to the support plate 103. A large number of hollow tubes 402 are bonded together in an interlaced manner to form a mesh structure. The elastic deformation is used to prolong the impact time and dissipate vibration energy. Since each hollow tube 402 is independent, the tearing of a few hollow tubes 402 has little impact on the efficiency of the entire energy-absorbing component 4, and prevents the hydraulic buffer column 102 and the spring 104 from being compressed to their limit stroke in a short time, thus extending their service life.

[0030] Working principle: The generator set is mounted on the fixed platform 301 through the mounting holes 305 and the rubber pads 304. The casters are connected to the bottom of the connecting seat 101 through the caster connection holes 107. When the generator is working or the casters move, vibration is generated. The vibration is transmitted to the connecting block 201 through the fixed platform 301. The vertical vibration drives the connecting block 201 to rise and fall. The bracket 202 drives the rubber wheel 203 to move up and down along the limiting groove 106, compressing the hollow tube 402 located below. A large number of hollow tubes 402 are interwoven and bonded together to form a mesh structure. The elastic deformation prolongs the impact time and dissipates the vibration energy. Furthermore, since each hollow tube 402 is independent, the tearing of a few hollow tubes 402 has little impact on the efficiency of the entire energy absorption assembly 4, preventing the hydraulic buffer column 102 and spring 104 from being compressed to their limit stroke in a short time, thus extending their service life. The vertical vibration of the connecting block 201 is buffered by the oil flow resistance inside the hydraulic buffer column 102 in conjunction with the elastic force generated by the compression of the spring 104. The horizontal vibration drives the connecting block 201 to move towards the inner wall of the connecting seat 101. The rubber wheel 203 generates elastic deformation to suppress shaking. After the generator is turned off, the diesel fuel and debris in the collection trough 302 are collected from the cleaning port 303.
