DETAILED DESCRIPTION

[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present application, the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the features of the embodiments of the present application can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present application. However, the embodiments of the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection provided by the embodiments of the present application is not limited to the specific embodiments disclosed below.

[0039] Refer to the following Figures 1 to 7 Some embodiments provided according to the present application are described.

[0040] like Figure 1 and Figure 2As shown, a hydraulic support top beam 10 proposed in an embodiment of the present application is used for a tunnel top plate 310, and a safety net 312 and an anchor cable 314 are arranged on the tunnel top plate 310. The anchor cable 314 is used to anchor the safety net 312 to the tunnel top plate 310. The hydraulic support top beam 10 includes a top beam body 110, a support body 120 and a connecting piece 130. Specifically, the support body 120 is arranged on the upper surface of the top beam body 110 and is detachably connected to the top beam body 110, and is used to support the safety net 312. There are multiple support bodies 120, and the multiple support bodies 120 are arranged at intervals. A groove 150 is formed between two adjacent support bodies 120, and the groove 150 is used to accommodate the anchor cable 314. The connecting piece 130 is used to connect the top beam body 110 and the support body 120.

[0041] The hydraulic support top beam 10 provided in this embodiment is used for the tunnel top plate 310, and a safety net 312 and an anchor cable 314 are arranged on the tunnel top plate 310. The anchor cable 314 is used to anchor the safety net 312 to the tunnel top plate 310. The hydraulic support top beam 10 includes a top beam body 110, a support body 120 and a connector 130. The support body 120 is arranged on the upper surface of the top beam body 110 and is detachably connected to the top beam body 110 to support the safety net 312. There are multiple support bodies 120, and the multiple support bodies 120 are arranged at intervals. A groove 150 is formed between two adjacent support bodies 120, and the groove 150 is used to accommodate the anchor cable 314. The connector 130 is used to connect the top beam body 110 and the support body 120. It can be understood that a safety net 312 and an anchor cable 314 are provided on the tunnel roof 310. The anchor cable 314 is used to anchor the safety net 312 to the tunnel roof 310. By supporting the safety net 312 through the support body 120, the hydraulic support top beam 10 can be effectively pushed onto the safety net 312 of the machine tunnel roof instead of the anchor cable 314, thereby providing a certain protection for the anchor cable 314 and allowing the more expensive anchor cable 314 to be recycled and reused. The structure is simple and easy to load and unload.

[0042] like Figure 3 As shown, in some embodiments, optionally, the connecting member 130 includes a first pin shaft 132 and a second pin shaft 134. The first pin shaft 132 is inserted on the support body 120 and the top beam body 110, and passes through the support body 120 and the top beam body 110. The second pin shaft 134 is inserted at one end of the first pin shaft 132 away from the support body 120, and is used to limit the displacement of the support body 120 relative to the top beam body 110 along the direction of the first pin shaft 132. By inserting the first pin shaft 132 into the support body 120 and the top beam body 110, and locking the first pin shaft 132 with the second pin shaft 134, the support body 120 can be prevented from falling off the top beam body 110.

[0043] like Figure 4As shown, in some embodiments, optionally, the connecting member 130 also includes a third pin shaft 136, the third pin shaft 136 is spaced apart from the first pin shaft 132, and the third pin shaft 136 is inserted into the support body 120 and the top beam body 110, thereby limiting the support body 120 from rotating.

[0044] like Figure 5 As shown, in some embodiments, optionally, a first sleeve 112 is provided on the top beam body 110 , and the first sleeve 112 is used to insert the first pin shaft 132 .

[0045] In some embodiments, optionally, a second sleeve 114 is further provided on the top beam body 110 , and the second sleeve 114 is spaced apart from the first sleeve 112 for inserting a third pin shaft 136 .

[0046] In some embodiments, optionally, the length of the first pin shaft 132 is greater than the sum of the height of the support body 120 and the length of the first sleeve 112, so that the second pin shaft 134 can be inserted into the end of the first pin shaft 132 away from the support body 120, so that the support body 120 cannot fall off the top beam body 110.

[0047] In some embodiments, optionally, the length of the third pin shaft 136 is less than the sum of the height of the support body 120 and the length of the second sleeve 114, which can limit the support body 120 from rotating, thereby fixing the support body 120 on the top beam body 110, with a simple structure and easy loading and unloading.

[0048] Specifically, the number of support bodies 120 can be 3, and the three support bodies 120 are arranged at intervals on the top beam body 110. The length of the first pin shaft 132 close to one end of the top beam body 110 is greater than the sum of the height of the support body 120 and the length of the first sleeve 112 on the top beam body 110. The first pin shaft 132 is then locked with the second pin shaft 134 to prevent the support body 120 from falling off. The length of the third pin shaft 136 close to the other end of the top beam body 110 is less than the height of the support body 120 plus the length of the second sleeve 114, which only limits the support body 120 from rotating.

[0049] like Figure 6 As shown, in some embodiments, optionally, the support body 120 is surrounded by a first side wall 142, a second side wall 144, a third side wall 146 and a fourth side wall 148. The first side wall 142 is used to support the safety net 312. The length of the third side wall 146 is the same as the length of the top beam body 110.

[0050] In some embodiments, optionally, a first through hole 122 and a second through hole 124 are provided on the support body 120 , the first through hole 122 corresponds to the first sleeve 112 and is used to insert the first pin 132 , and the second through hole 124 corresponds to the second sleeve 114 and is used to insert the third pin 136 .

[0051] like Figure 7 As shown, a hydraulic support 20 proposed according to an embodiment of the present application includes a hydraulic support top beam 10 as described in any of the above embodiments.

[0052] The hydraulic support 20 provided according to the embodiment of the present application includes the hydraulic support top beam 10 as in any of the above embodiments, and thus it has all the beneficial effects of the hydraulic support top beam 10 as in any of the above embodiments, which will not be described in detail herein.

[0053] like Figures 1 to 6 As shown, according to a specific embodiment of the hydraulic support top beam 10 proposed in the present application, it can effectively hit the machine tunnel roof safety net 312 instead of the anchor cable 314, thus providing certain protection for the anchor cable 314 and allowing the relatively high-cost anchor cable 314 to be recycled and reused.

[0054] Specifically, the hydraulic support top beam 10 is composed of a top beam body 110 , a support body 120 , a first pin shaft 132 , a second pin shaft 134 , and a third pin shaft 136 .

[0055] The front row of the top beam 110 is provided with three first pins 132 , the length of the first pin 132 is greater than the sum of the height of the support body 120 and the length of the first sleeve 112 on the top beam 110 , and then the first pin 132 is locked with the second pin 134 to prevent the support body 120 from falling off.

[0056] Three third pins 136 are arranged in the rear row of the top beam body 110. The length of the third pins 136 is less than the height of the support body 120 plus the length of the second sleeve 114 on the top beam body 110, and only restricts the support body 120 from rotating.

[0057] In summary, the beneficial effects of the embodiments of the present application are:

[0058] 1. A support body is added to the original ordinary top beam, which can effectively support the safety net of the machine tunnel roof instead of the anchor cable, thus providing a certain protection for the anchor cable and allowing the high-cost anchor cable to be recycled and reused. The structure is simple and easy to load and unload.
