Description

Technical Field

[0001] This utility model relates to an anti-roof collapse support anchor bolt, belonging to the technical field of mining protection devices. Background Technology

[0002] Roof falls have a high incidence rate in mining operations. To ensure worker safety, the industry has established strict protective operating procedures, among which installing temporary rock bolts to support the roof in roadways is an important measure. However, traditional rock bolts have the following shortcomings in practical applications:

[0003] When installed manually, the contact between the anchor bolt and the roadway roof can easily cause ore to fall off the supported area. Traditional anchor bolts are limited by the protection area of ​​the top support plate, making it difficult to form an effective shielding and protection area for workers below. This can lead to falling ore injuring workers below, posing a significant safety hazard. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an anti-roofing support anchor rod, which enhances top protection, prevents local rockfalls from injuring workers below during anchor rod installation, and improves the safety of anchor rod installation operations.

[0005] This utility model provides an anti-collapse support anchor rod, comprising: a primary support rod hinged to a base, a telescopic drive component at the top of the primary support rod; a secondary support rod on the telescopic drive component, a nut threaded onto the outer wall of the secondary support rod, and a jacking sleeve slidably connected to the secondary support rod, the nut driving the jacking sleeve to move axially along the secondary support rod.

[0006] The top of the secondary strut is equipped with a support plate, and several baffles are hinged to the outside of the support plate. The baffles are hinged to the lifting sleeve through the connecting rod, and the lifting sleeve can drive the baffles to move through the connecting rod.

[0007] The sides of the baffles are connected to a cover, which can cover the gaps between adjacent baffles.

[0008] Furthermore, the bottom end of the primary strut is provided with a ball head, and the base is hinged to the ball head, forming a spherical hinge.

[0009] Furthermore, the telescopic drive component is equipped with a lever for controlling its own lifting and lowering, and the output end of the telescopic drive component is equipped with an adapter seat, with the secondary support rod fixedly connected to the inside of the adapter seat.

[0010] Furthermore, the outer wall of the secondary strut is provided with a threaded section and a guide block.

[0011] The nut is connected to the threaded part; the lifting sleeve is connected to the guide block.

[0012] Furthermore, several handles are evenly provided on the side of the nut.

[0013] Furthermore, a positioning cone is provided on the top of the support plate.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The deployment of the baffle and cover increases the protective area at the top of the anchor bolt, providing a larger safety coverage for installation workers below the anchor bolt. Falling rocks can slide down the baffle and cover to one side of the anchor bolt, effectively reducing the safety risk of falling rocks injuring workers. Attached Figure Description

[0029] like Figures 1-2 As shown, this embodiment is achieved through the following technical solution: a primary support rod 2 is hinged on the base 1, and a telescopic drive component 3 is provided on the top of the primary support rod 2; a secondary support rod 4 is provided on the telescopic drive component 3, and a nut 5 is threadedly connected to the outer wall of the secondary support rod 4; a lifting sleeve 6 is also slidably connected to the secondary support rod 4, and the nut 5 can drive the lifting sleeve 6 to move axially along the secondary support rod 4.

[0030] A support plate 10 is provided at the top of the secondary strut 4. Several baffles 8 are hinged to the outside of the support plate 10. The baffles 8 are hinged to the lifting sleeve 6 through the connecting rod 7. The lifting sleeve 6 can drive the baffles 8 to move through the connecting rod 7.

[0031] A cover 9 is connected to the side of the baffle 8, and the cover 9 can cover the gap between adjacent baffles 8.

[0032] Specifically, the bottom end of the primary strut 2 is provided with a ball head 201, and the base 1 is hinged to the ball head 201, forming a spherical hinge. The spherical hinge base 1 can adjust the tilt angle of the bottom support surface according to the terrain, thereby better adapting to the rugged ground in the tunnel and ensuring reliable support.

[0033] Specifically, the telescopic drive component 3 is provided with a lever 301 for controlling its own lifting and lowering, and the output end of the telescopic drive component 3 is provided with an adapter 302, and the secondary support rod 4 is fixedly connected to the inside of the adapter 302.

[0034] In this embodiment, the telescopic drive component 3 is a hydraulic jack, and the end of the lever 301 is equipped with a pedal, such as... Figure 1 As shown, the pedal can be manually pressed to move the lever 301, thereby adjusting the extension length of the telescopic drive component 3.

[0035] Specifically, the outer wall of the secondary strut 4 is provided with a threaded part 401 and a guide block 402.

[0036] Nut 5 is connected to threaded part 401; lifting sleeve 6 is connected to guide block 402.

[0037] In this embodiment, the nut 5 is rotatably connected to the lifting sleeve 6. Rotating the nut 5 can drive the lifting sleeve 6 to rise or fall on the secondary support rod 4. When the lifting sleeve 6 rises, it drives the baffle 8 to rise through the connecting rod 7, and the covering cloth 9 unfolds as the baffle 8 rises; conversely, when the lifting sleeve 6 falls, the baffle 8 retracts, and the covering cloth 9 stacks and shrinks as the baffle 8 retracts.

[0038] Specifically, the nut 5 has several handles 501 evenly distributed on its side.

[0039] Specifically, a positioning cone 1001 is provided on the upper part of the support plate 10.

[0040] The specific working principle of this utility model is as follows:

[0041] During use, the operator holds the anchor rod body to keep it upright, rotates the nut 5 to unfold the baffle 8 and the cover 9, and then steps on the lever 301 to control the output end of the telescopic drive 3 to extend, causing the secondary support rod 4 and the support plate 10 to rise. The positioning cone 1001 on the support plate 10 first penetrates the top of the roadway to prevent the anchor rod from shifting during the support process. Furthermore, as the telescopic drive 3 continues to extend, the top of the support plate 10 and the baffle 8 contacts the top of the roadway, at which point the entire anchor rod is supported into the roadway. During the support process, falling gravel slides down the top of the baffle 8 and the cover 9, while the operator is positioned below the baffle 8 and the cover 9 to prevent injury from falling ore.

[0042] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
