Detailed Description

The following description of the embodiments refers to the accompanying drawings.

As shown in fig. 1, the V-shaped shock absorbing device in this embodiment includes an upper support 10, a lower support 30, and a bolt assembly 50 for locking the upper and lower supports. The V-shaped shock absorbing device is commonly used for fixedly mounting an engine on a frame of an engineering machine, wherein the upper support 10 is fixedly connected with the engine through a bolt, and the lower support 30 is fixedly connected with the frame through welding or a bolt.

The upper support 10 is provided with an upper V-shaped plate 11, and the lower support 30 is provided with a lower V-shaped plate 31. The notches of the upper V-shaped plate 11 and the lower V-shaped plate 31 are arranged upwards, the upper V-shaped plate 11 is positioned above the lower V-shaped plate 31, and the central planes of the upper V-shaped plate and the lower V-shaped plate are superposed. The inclined plates on the two sides of the upper V-shaped plate 11 are respectively parallel to the inclined plates on the two sides of the lower V-shaped plate 31. A shock pad arranged in a V shape is installed between the upper V-shaped plate 11 and the lower V-shaped plate 31. The centre plane of the shock-absorbing pad of the V-shaped arrangement coincides with the centre plane of the upper V-shaped plate 11.

In this embodiment, the shock absorbing pad arranged in a V shape is a V-shaped shock absorbing pad 21, the shock absorbing pad plates on both sides of the V-shaped shock absorbing pad 21 are connected with each other at the bottom, and are a part, and are symmetrical about the central plane, and the bottom of the shock absorbing pad is provided with a hole for passing a bolt. The bolt 51 in the bolt assembly 50 passes through the hole at the bottommost part of the V-shaped shock pad 21 to limit the V-shaped shock pad 21, and the V-shaped shock pad 21 is prevented from falling off between the upper V-shaped plate 11 and the lower V-shaped plate 31 in the using process.

In other embodiments, the two shock absorbing pads arranged in the V-shape may be two shock absorbing pads symmetrically arranged about the central plane of the upper V-shaped plate, and are two independent parts, that is, the two shock absorbing pads are respectively arranged between the inclined plates on both sides of the upper V-shaped plate 11 and the inclined plates on both sides of the lower V-shaped plate 31, and the two shock absorbing pads are not connected with each other. When the shock pad arranged in the V shape is composed of two independent shock pads, an anti-dropping limiting device, such as a baffle plate or a screw, needs to be arranged on the upper support or the lower support to limit the shock pad between the upper V-shaped plate and the lower V-shaped plate.

The upper side of the upper V-shaped plate 11 is provided with a horizontal plate 12 vertical to the central plane of the upper V-shaped plate 11, and the two sides of the horizontal plate 12 are correspondingly welded with the inclined plates at the two sides of the upper V-shaped plate 11.

The bolt assembly 50 includes a bolt 51, an upper press plate 52, a lower washer 54, and a nut 53. The bolt assemblies 50 are arranged on the center planes of the upper and lower V-shaped plates and the V-shaped cushion 21. The upper platen 52 is disposed on the upper side of the horizontal plate 12, and the upper cushion 23 is installed between the upper platen 52 and the horizontal plate 12. The threaded end of the bolt 51 sequentially penetrates through the upper pressure plate 52, the upper shock pad 23, the horizontal plate 12, the upper V-shaped plate 11, the V-shaped shock pad 21 (or a gap between the upper V-shaped plate and the lower V-shaped plate), the lower V-shaped plate 31 and the lower pad 54 from top to bottom, and then is in threaded fit with the nut 53, so that the upper support 10 and the lower support 30 are fixedly connected.

The bolt assembly 50 connects the upper and lower cradles 10 and 30. After the V-shaped shock absorbing device is installed, the V-shaped shock absorbing pad 21 and the upper shock absorbing pad 23 have a certain pre-compression amount, so that the shock absorbing device has a certain rigidity. When the upper support 10 descends relative to the lower support to cause the V-shaped shock pad 21 to be compressed, the distance between the horizontal plate 12 and the lower end (nut) of the bolt is reduced, the reduction is the compression amount of the V-shaped shock pad 21 in the vertical direction, the distance between the horizontal plate 12 and the upper end (bolt head) of the bolt is correspondingly increased, and at the moment, the upper shock pad 23 recovers the corresponding compression amount under the elastic action. Accordingly, when upper support 10 moves upward relative to lower support 30, upper cushion 23 is further compressed, and V-shaped cushion 21 is restored to the corresponding compression amount by its elasticity. Therefore, when the upper support 10 moves up and down relative to the lower support 30, the bolt assembly is still kept fixed relative to the upper support and the lower support under the pre-compression elastic force of the upper shock absorption pad 23 or the V-shaped shock absorption pad 21, and the phenomenon that the bolt is loosened relative to the upper support and the lower support cannot occur.

The centrally arranged bolt assembly 50 easily enables the stress on the two sides of the central plane of the upper V-shaped plate and the lower V-shaped plate to be equal to that on the two sides of the V-shaped shock pad 21, and damage caused by uneven stress on the two sides of the shock pad is not easy to occur.

As shown in fig. 3 and 4, the rigid support is formed by an upper sleeve 71 and a lower sleeve 72 that fit over the bolts in the bolt assembly. The upper sleeve 71 is a T-shaped sleeve with a large diameter end at the upper end, and the lower sleeve 72 is a straight sleeve with a lower end welded to the lower V-shaped plate 31. The upper sleeve 71 is located between the horizontal plate 12 and the upper V-shaped plate 11, the upper end of the lower sleeve 72 extends upward through the V-shaped cushion 21, and when the upper support 10 moves downward, the upper end of the lower sleeve 71 moves upward through the hole in the upper V-shaped plate 11 relative to the upper support until it is connected in abutting contact with the lower end of the upper sleeve 71.

In this embodiment, the lower sleeve 71 may also be a T-shaped sleeve with a large diameter end at the lower end, and in this case, the lower sleeve 71 is also sleeved on the bolt, and the lower end of the lower sleeve is connected to the upper side surface of the lower V-shaped plate 31 in an abutting contact manner.

In this embodiment, the upper sleeve 71 and the lower sleeve 72 may be combined into a straight sleeve or a T-shaped sleeve with the same upper and lower diameters, the sleeve is installed from bottom to top, the upper end of the sleeve penetrates through the V-shaped cushion 21 and the upper V-shaped plate 11, and when the upper support 10 is stationary relative to the lower support 30, at least one of the lower side surface of the horizontal plate 12 and the upper side surface of the lower V-shaped plate 31 has a gap with the corresponding end of the sleeve.

As shown in fig. 4, the upper support 10 further includes an end upper inclined plate 13 welded and fixed to one end of the upper V-shaped plate 11, and the end upper inclined plate 13 is symmetrically disposed with respect to a central plane of the upper V-shaped plate 11.

An end lower inclined plate 32 is welded and fixed in a groove of the lower V-shaped plate 31, the end lower inclined plate 32 is arranged in parallel with the end upper inclined plate 13, an end face shock absorption pad 22 is arranged between the end upper inclined plate 13 and the end lower inclined plate 32, the upper side face and the lower side face of the end face shock absorption pad 22 are respectively in contact connection with the end upper inclined plate 13 and the end lower inclined plate 32, and the end face shock absorption pad is tightly pressed and fixed between the end upper inclined plate 13 and the end lower inclined plate 32. In order to prevent the end face shock pad 22 from falling off in the using process, a limit block or a limit screw and the like can be arranged on the end upper inclined plate or the end lower inclined plate to limit the end face shock pad.

In the present embodiment, as shown in fig. 2, the vertical direction of the V-shaped damper when used after being installed on the machine is the X direction, the direction perpendicular to the center plane of the upper V-shaped plate is the Z direction, and the direction perpendicular to both the X direction and the Z direction is the Y direction.

The included angle between the end upper inclined plate 13 and the vertical direction (X direction) is equal to the included angle between the inclined plates at two sides of the upper V-shaped plate 11 and the vertical direction.

Because damping device all is installed in pairs when the installation is used, two damping device that install in pairs can realize the two-way shock attenuation buffering in Y direction. In the present embodiment, the V-shaped cushion 21 can perform cushion in the X direction and the Z direction, and the end face cushion 22 can perform cushion in the Y direction, so as to perform cushion in three directions.

In this embodiment, when the engine moves upward relative to the frame, the lower end of the bolt assembly 50 acts on the lower support to be fixed relative to the frame, and the horizontal plate 12 presses the upper cushion 23 upward to realize upward buffering.

In the embodiment, when the engine moves downwards relative to the frame, the upper V-shaped plate 11 of the upper support 10 presses the V-shaped shock pad 21, so as to realize downward buffering and shock absorption. When the impact of downward movement of the engine is too large, and the V-shaped shock absorption pad 21 and the end shock absorption pad 22 are compressed to a predetermined thickness, the upper end and the lower end of the upper sleeve 71 are respectively connected with the lower side surface of the horizontal plate 12 and the upper end of the upper sleeve 72 in an abutting contact manner, the upper sleeve 71 and the lower sleeve 72 support the upper support 10, and the upper V-shaped plate 11 is prevented from continuously moving downwards relative to the lower V-shaped plate 31 to compress the V-shaped shock absorption pad and the end shock absorption pad, so that the shock absorption pad is not excessively compressed to damage the elasticity of the shock absorption pad. Ensure the shock pad to compress in the elastic range, thereby ensuring the shock absorption effect. When the shock pad is compressed to a preset thickness, the shock pad reaches the maximum allowable compression amount, if the shock pad is continuously compressed, the elasticity of the shock pad can be damaged, and the shock pad cannot recover the original state after the action is eliminated.

This embodiment also provides another embodiment of the rigid support member in the V-shaped vibration damper, as shown in fig. 5. In this embodiment, the rigid support is constituted by a plurality of steel columns 73 arranged between the upper V-shaped plate 11 and the lower V-shaped plate 31.
