[0032] Anti-drop structure for damper connecting rod:

[0033] like Figure 1 , 2 As shown, an anti-falling structure for a damper connecting rod in an embodiment of the present application includes a base 11 and a hanging rope 12, the base 11 is used to be fixedly mounted on a damper frame 21, the first end of the hanging rope 12 is connected to the base 11, and the second end of the hanging rope 12 is used to connect to the damper connecting rod 22.

[0034] In this embodiment, a base 11 is fixedly mounted on the damper frame 21, a first end of a lifting rope 12 is connected to the base 11, and a second end of the lifting rope 12 is connected to the damper connecting rod 22. When the damper connecting rod 22 is collided with and falls by an over-height vehicle or device, the lifting rope 12 will hold the damper connecting rod 22 to prevent the damper connecting rod 22 from falling, thereby preventing it from endangering the safety of personnel and equipment working underground.

[0035] like Figure 1 , 2 As shown, in a preferred embodiment, there are two bases 11 fixedly mounted on a damper frame 21, each base 11 is connected to a suspension rope 12, and the two suspension ropes 12 are commonly connected to the damper connecting rod 22. When the damper connecting rod 22 falls off, the damper connecting rod 22 can be pulled more stably, thereby improving the stability of the connection.

[0036] like Figure 1 As shown, in another embodiment, the second end of the suspension rope 12 is further connected to a clamp 13 , and the clamp 13 is used to clamp the damper connecting rod 22 .

[0037] In this embodiment, when installing the anti-falling structure, the damper connecting rod 22 can be directly clamped with the clamp 13. The on-site installation process is convenient and quick, which does not affect the normal operation of the damper and can continue to provide protection for the safe passage of the damper.

[0038] In a preferred embodiment, the interior of the clamp 13 is also provided with raised anti-slip grooves or gaskets. The gasket is made of one of silicone, rubber, and plastic. The shape of the gasket can also be set to anti-slip grooves to enhance the friction between the clamp 13 and the damper connecting rod 22. When the damper connecting rod 22 falls off, the clamp 13 can clamp the damper connecting rod 22 more stably, thereby improving stability.

[0039] In another preferred embodiment, the clamp 13 is further provided with a self-locking structure. During on-site installation, the self-locking structure can be used to lock the clamp 13 on the damper connecting rod 22, thereby improving the stability of the clamp 13 clamping the damper connecting rod 22.

[0040] like Figure 1 As shown, at least one elastic member 14 is also provided on the sling 12, and both ends of the elastic member 14 are connected to the sling 12;

[0041] The length of the connecting portion between the two ends of the suspension rope 12 and the elastic member 14 is less than the limit length of the elastic member 14 .

[0042] In this embodiment, both ends of the elastic member 14 are connected to the same suspension rope 12, and the maximum length of the elastic member 14 is greater than the length of the connecting portion between the suspension rope 12 and the two ends of the elastic member 14. When the damper connecting rod 22 falls off, the suspension rope 12 tends to be straightened. At this time, the elastic member 14 is pulled apart, thereby offsetting part of the impact caused by the external force, preventing the suspension rope 12 from being disconnected from the damper connecting rod 22 due to excessive force in an instant, and the damper connecting rod 22 has a better anti-falling effect.

[0043] like Figure 3 As shown, in one embodiment, at least two fixing members 15 are further provided at the upper end of the clamp 13 , and one end of the suspension rope 12 passes through the fixing member 15 and is fixed to the clamp 13 by the fixing member 15 .

[0044] In this embodiment, at least two fixing members 15 fix one end of the suspension rope 12 to the clamp 13, so that the connection between the suspension rope 12 and the clamp 13 is more stable.

[0045] like Figure 3 As shown, in a preferred embodiment, the portion of the suspension rope 12 connected to the fixing member 15 forms a fixing section 121, and the remaining portion forms a suspension section 122;

[0046] One end of the elastic member 14 is connected to the fixing section 121 , and the other end of the elastic member 14 is connected to the suspension section 122 .

[0047] In this embodiment, one end of the elastic member 14 is connected to the portion where the suspension rope 12 is connected to the fixing member 15, and the other end is connected to the remaining portion of the suspension rope 12. The portion where the suspension rope 12 is connected to the fixing member 15 is more stable, and one end of the elastic member 14 is connected thereto. When the damper connecting rod 22 falls off, the connection between the elastic member 14 and the suspension rope 12 is more stable and will not fall off easily, thereby increasing the stability of the anti-falling structure 1.

[0048] like Figure 4 As shown, in another embodiment, the base 11 includes two cross-connected elastic brackets 110 , and the first end of the suspension rope 12 is connected to the cross-connection of the two elastic brackets 110 .

[0049] In this embodiment, the base 11 installed on the damper frame 21 includes two cross-connected elastic brackets 110, one end of the suspension rope 12 is connected to the cross-connection of the two elastic brackets 110, and the other end is used to connect the damper connecting rod 22. The base 11 is used to remain fixed with the damper frame 21. When the damper connecting rod 22 falls, it can provide pulling force to the suspension rope 12 to prevent the damper connecting rod 22 from continuing to fall downward.

[0050] like Figure 4 As shown, in a preferred embodiment, the elastic bracket 110 includes a central plate 1101, two inclined plates 1102 and two fixed plates 1103;

[0051] Two fixed plates 1103 are connected to two ends of the center plate 1101 through an inclined plate 1102 respectively, and the fixed plates 1103 are parallel to the plane where the center plate 1101 is located;

[0052] The central plates 1101 of the two elastic brackets 1110 are cross-connected, and the fixing plate 1103 is used to connect the damper frame 21 .

[0053] In this preferred embodiment, two fixed plates 1103 are fixedly connected to the damper frame 21, and each of the two fixed plates 1103 is connected to an inclined plate 1102, and there is a center plate 1101 in the middle of the two inclined plates 1102. The five plates form an elastic bracket 110. The two elastic brackets 110 have good elasticity and can be deformed when pulled by external force, thereby buffering the pulling force and preventing the fixing points from falling off, thereby improving the anti-falling effect of the structure and ensuring the safety of underground passage.

[0054] In another preferred embodiment, the central plates 1101 of the two elastic brackets 110 are cross-connected by bolts.

[0055] Fasteners such as bolts can enable the two cross-connected brackets to rotate relative to each other, can flexibly adapt to the installation space, and are more convenient during installation.

[0056] like Figure 1 , 4 As shown, in a preferred embodiment, the base 11 further includes a hanging seat 111 disposed at the cross-connection of the two elastic brackets 110 , and the hanging seat 111 is connected to the first end of the hanging rope 12 .

[0057] In this embodiment, a hanging seat 111 is further provided at the cross-connection of the two elastic brackets 110. The hanging seat 111 is used to connect with the hanging rope 12, providing a hanging point to facilitate the hanging of the hanging rope 12 and facilitate on-site installation.

[0058] The hanging seat 111 includes a bottom part and a connecting part. The bottom is fixedly installed at the cross connection of the two elastic brackets 110. The connecting part horizontally penetrates the bottom part to form a hanging point. The hanging rope 12 can be tied to the connecting part to facilitate the installation connection between the hanging rope 12 and the base 11.

[0059] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0060] like Figure 1-4As shown, in an optimal embodiment, at least two anti-falling structures for the damper connecting rod are installed on the damper frame 21, each anti-falling structure 1 includes a base 11 and a hanging rope, at least two hanging ropes 12 are connected to the damper connecting rod 21, wherein the first end of the hanging rope 12 is connected to the base 11, and the second end of the hanging rope 12 is connected to a clamp 13, and the clamp 13 is directly clamped to the damper connecting rod 21, which is more convenient during on-site installation. The inside of the clamp 13 that clamps the damper connecting rod 21 is also provided with anti-skid grooves or gaskets for preventing slipping, which increases the friction between the clamp 13 and the damper connecting rod 21, and enables the clamp to clamp the damper connecting rod 21 more stably.

[0061] At least one elastic member 14 is also connected to the suspension rope 12. The length of the connecting portion between the suspension rope 12 and the two ends of the elastic member 14 is less than the maximum length of the elastic member 14. When the damper connecting rod 21 falls off, the suspension rope 12 will be straightened by the tension. At this time, the elastic member 14 provides a certain elastic support for the suspension rope 12, so that the elastic member 14 can help the suspension rope 12 to offset part of the impact force, avoid the suspension rope 12 being subjected to instantaneous force to cause the suspension point to collapse, and improve the anti-falling effect of the damper connecting rod 21.

[0062] At least two fixing members 15 are also provided on the clamp. One end of the suspension rope 12 passes through the fixing member 15 and is fixed to the clamp 13 by the fixing member 15, so that the end of the suspension rope 12 connected to the clamp 13 can be more stable and not easily disconnected.

[0063] A base 11 with good elasticity is installed on the damper frame. The base 11 includes two cross-connected elastic brackets 110. Each elastic bracket 110 includes five plates, two fixed plates 1103 are fixedly connected to the damper frame 21, and the two fixed plates 1103 are each connected to an inclined plate 1102, and a center plate 1101 is provided between the two inclined plates 1102. The base 11 also includes a hanging seat 111 installed at the cross connection of the two elastic brackets 110, that is, the hanging seat 111 installed on the two center plates 1101. The hanging seat 111 forms a hanging point, so that the hanging rope 12 can be more conveniently connected to the hanging seat 111.

[0064] The two cross-connected elastic brackets 110 are connected by fasteners such as bolts, and the two elastic brackets 110 can rotate relative to each other and can flexibly adapt to different installation environments.

[0065] throttle:

[0066] like Figure 2 As shown, the damper 2 includes a damper frame 21, a damper connecting rod 22 mounted on the damper frame 21 and an anti-falling structure for the damper connecting rod 22 as described above, and at least one anti-falling structure 1 is connected between the damper frame 21 and the damper connecting rod 22.

[0067] In a preferred embodiment, two anti-falling structures 1 for the damper connecting rod 22 are installed on the damper frame 21 to prevent one end of the damper connecting rod 22 from touching personnel or equipment when it falls. The anti-falling structure 1 is installed on the damper connecting rod 22. When the damper connecting rod 22 falls off, the damper connecting rod 22 can be pulled as soon as possible to prevent the damper connecting rod 22 from touching industrial personnel or equipment working underground.
