Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment of the present invention, as shown in fig. 1 to 13, a supporting and hanging device for mounting an electromechanical device includes a top seat 102, a supporting platform 120, a pipe bracket, and an adjusting mechanism. The top mount 102 is suspended from the wall by the hanger bar 101. The support platform 120 is fixedly mounted to the top base 102 by a connector and is located below the top base 102. The number of the pipe brackets is two, the two pipe brackets are arranged on the upper portion of the supporting table 120 at left and right intervals, each pipe bracket comprises an upper top plate 103 and a lower top plate 121 which are horizontally arranged, and the upper top plate 103 is connected to the lower surface of the top base 102 through a first spring 104. The lower top plate 121 is connected to the upper surface of the support table 120 through a second spring 123, when the pipe 110 is installed, the upper and lower sides of the pipe 110 respectively abut against the upper top plate 103 and the lower top plate 121, and both the first spring 104 and the second spring 123 are in a compressed state. If the electromechanical devices installed in the two tubes 110 have different masses, the tube 110 having the larger mass moves down more and the corresponding second spring 123 is compressed more.
The adjusting mechanism comprises two limiting assemblies and an adjuster, and each limiting assembly comprises a limiting plate 161, a supporting column 131, a supporting rod 162 and a third spring 164. The limiting plates 161 of each limiting component are two, and the two limiting plates 161 are vertically arranged on the left side and the right side of the pipeline 110 respectively and are abutted to the pipeline 110. The support column 131 is disposed below the pipe 110 and slidably mounted to the support table 120 in the left-right direction. The number of the stay bars 162 is two, the two stay bars 162 are respectively arranged on the left side and the right side of the supporting column 131, each stay bar 162 is arranged in the left-right direction, a horizontally arranged sleeve rod 163 is installed at the lower end of each limiting plate 161, and one stay bar 162 is slidably sleeved on each limiting plate 161 along the left-right direction through the sleeve rod 163. The number of the third springs 164 is two, each third spring 164 is sleeved on one support rod 162, one end of each third spring is connected to the support column 131, the other end of each third spring is connected to the sleeve rod 163, and the third springs 164 are in a stretching state in an initial state, so that the two limiting plates 161 of each adjusting mechanism are kept against the left side and the right side of the pipeline 110. When the supporting platform 120 is vibrated, the supporting platform 120 may be driven to swing left and right through the connecting rod 141, so that the supporting platform 120 drives the two pipes 110 to move relatively, and the swinging of the pipes 110 may cause each of the first springs 104 and the second springs 123 to have different stresses. An adjuster is arranged between the two limiting assemblies, the adjuster is configured to cause the two supporting columns 131 to move leftwards or rightwards when the heights of the two lower top plates 121 are different and the supporting table 120 is vibrated, the moving amount of the supporting column 131 at the lower position is larger than that of the supporting column 131 at the higher position, and a third spring 164 connected with the supporting column 131 with the larger moving amount stores more energy.
Taking the example that the right pipe 110 is stressed greatly, since the moving amount of the right supporting column 131 is larger than that of the left supporting column 131, the energy storage of the third spring 164 of the right adjusting mechanism is larger than that of the third spring 164 of the left adjusting mechanism, and according to newton's second law F = ma, since the right is heavy and the left is light (i.e., mright > mrleft), the force applied to the duct 110 by the third spring 164 of the adjustment mechanism on the right side through the stopper plate 161 is greater than the force applied to the duct 110 by the third spring 164 of the adjustment mechanism on the left side through the stopper plate 161 (i.e., fleight > fleleft), the F/M ratio of the two pipelines is approximate through the adjustment of the adjusting mechanism, so the acceleration of the left and right pipelines 110 is approximately equal (a is right and is approximately equal to a left), thus, the two pipes 110 can remain substantially stationary until a shock is received, and no collision can occur.
In one embodiment, the adjuster includes a second bayonet 122, a telescopic hinge rod 132, a positioner 134, a linkage 133, a hydraulic drive assembly, and a transmission. Two mounting slots are provided on the support table 120, each of which is located below one of the lower top plates 121.

The two ends of the telescopic hinge rod 132 are respectively hinged to the two second inserting rods 122, and the telescopic hinge rod 132 is telescopically arranged along the length direction thereof, so that the height of the telescopic hinge rod 132 can be conveniently adjusted according to the heights of the two second inserting rods 122.
A horizontally disposed sliding groove is further disposed inside the supporting platform 120, the sliding groove is located between the two second inserting rods 122, and the position adjuster 134 is horizontally slidably disposed in the sliding groove along the left-right direction. The connecting rod 133 is perpendicular to the telescopic hinge rod 132 and is telescopically arranged along the length direction thereof, the upper end of the connecting rod is fixedly connected to the middle part of the telescopic hinge rod 132, and the lower end of the connecting rod is hinged to the position adjuster 134. When the two pipelines 110 are stressed differently, the telescopic hinged rod 132 is driven by the two second inserting rods 122 to have a higher end and a lower end, and the telescopic hinged rod 132 drives the position adjuster 134 to move to the higher side of the telescopic hinged rod 132 along the sliding groove through the connecting rod 133.
The hydraulic transmission assembly includes a hydraulic tank 135, a damping ring 136, and a switching valve 137. The number of the hydraulic tanks 135 is two, each hydraulic tank 135 is disposed below one pipe 110 and fixedly installed at the support table 120, and the inside of the hydraulic tank 135 is filled with damping fluid.

The on-off valve 137 is disposed inside the damping ring 136 for increasing or decreasing a liquid flow passage when rotating. The transmission element is configured to convert the left and right movement of the positioner 134 into the rotation of the on-off valve 137 around its axis, so that when the positioner 134 moves leftwards along the sliding groove, the on-off valve 137 on the right side reduces the liquid flow passage on the damping ring 136 on the right side, the on-off valve 137 on the left side increases the liquid flow passage on the damping ring 136 on the left side, when the positioner 134 moves rightwards along the sliding groove, the on-off valve 137 on the left side reduces the liquid flow passage on the damping ring 136 on the left side, and when the positioner 134 moves rightwards along the sliding groove, the on-off valve 137 on the right side increases the liquid flow passage on the damping ring 136 on the right side, so that the moving speeds and the displacement amounts of the two supporting columns 131 moving along the corresponding hydraulic tanks 135 are different, that is, the acting forces of the limiting plates 161 received by the two pipes 110 are different.
In one embodiment, as shown in fig. 8 and 10, the transmission member includes a connecting rod 141, a connecting sleeve 142, and a swivel 143.

In one embodiment, each damping cylinder comprises a damping cylinder body 171, a damping rod 172 and a damping plate 173, and the inside of the damping cylinder body 171 has a large end and a small end, and is filled with liquid. The damping rod 172 is vertically disposed, one end of the damping rod is inserted into the cavity of the damping cylinder 171, the damping plate 173 is located in the cavity and fixedly connected to the damping rod 172, and the outer edge of the damping plate 173 is in contact with the peripheral wall of the small end of the cavity in an initial state.

When the two pipelines 110 are different in mass, the two pipelines 110 are different in height, taking the right-heavy and left-light as an example, the following working process is described:
when the vertical downward acting force of the electromechanical device on the right-side pipeline 110 is greater than the vertical downward acting force of the electromechanical device on the left-side pipeline 110, the second insertion rod 122 on the second left side of the right-side second insertion rod 122, the telescopic hinged rod 132 is driven by the second insertion rod 122, the right end is lower, the left end is higher, the connecting rod 133 is always perpendicular to the telescopic hinged rod 132, the connecting rod 133 drives the position adjuster 134 to move leftwards along the horizontal direction of the sliding groove, the position adjuster 134 drives the connecting rod 141 and the screw rod 144 to move synchronously when moving, because the screw rod 144 is in spiral fit with the connecting sleeve 142, the connecting sleeve 142 and the rotating ring 143 are driven to rotate around the axis thereof when moving, the connecting sleeve 142 drives the switch valve 137 to rotate, so that the liquid flow passage on the damping ring 136 on the right side becomes smaller, the liquid flow passage on the damping ring 136 on the left side becomes larger, that the damping capacity of the damping ring 136 on the right side to the damping liquid in the damping ring 136 is increased, the damping ring 136 on the left side has a reduced damping capacity for the damping fluid therein.
When an earthquake or strong shock occurs, the shock drives the support table 120 to swing left and right through the wall and shock waves, because the damping capacity of the damping ring 136 on the right side to the damping liquid in the damping ring 136 on the right side is greater than that of the damping ring 136 on the left side to the damping liquid in the damping ring 136 on the left side, the displacement of the support column 131 connected with the damping ring 136 on the right side is greater than that of the support column 131 connected with the damping ring 136 on the left side, the energy storage of the third spring 164 of the adjusting mechanism on the right side is greater than that of the third spring 164 of the adjusting mechanism on the left side, that is, the acting force of the limiting plate 161 on the pipeline 110 on the right side is greater than that on the pipeline 110 on the left side. According to newton's second law F = ma, since the right side is heavy and the left side is light (i.e., mright > mrleft), the force applied to the pipe 110 by the third spring 164 of the right-side adjustment mechanism through the limit plate 161 is greater than the force applied to the pipe 110 by the third spring 164 of the left-side adjustment mechanism through the limit plate 161 (i.e., fright > rfleft), the accelerations of the left and right pipes 110 are approximately equal (a-right ≈ a-left), and thus the two pipes 110 can be kept substantially stationary until the shock is applied, reducing the probability of collision of the pipes 110.
Further, by providing a plurality of third springs 164 and a hydraulic transmission assembly, the damage of the seismic transverse waves to the pipe 110 can be reduced, thereby reducing the occurrence of secondary disasters. In the vertical direction, the damage of the seismic longitudinal waves to the pipeline 110 can be weakened due to the action of the first spring 104, the second spring 123 and the damping cylinder.
When the left side pipe 110 is acted by the electromechanical device more than the right side pipe 110, the principle is the same and the actions are opposite.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
