[0002] Due to the special characteristics of the surrounding rock of the roof in a certain coal mine, the anchor mesh support used in some roadways could not meet the requirements, and the anchor cables needed to be used for full-section support. As a result, the original front-end beam lifting rings could not meet the support needs, and the front-end beam could not be used normally. After blasting or tunneling, the face could not be well supported, resulting in accidents caused by falling rocks from the roof and injuring people when personnel were supporting individual structures. Utility Model Content

[0003] The purpose of this invention is to provide a suspension system and dismantling device for a front extension beam supported by full-section anchor cables, so as to solve the problem that the front extension beam cannot be used normally when anchor cables are used for full-section support.

[0004] The present invention adopts the following technical solution: a suspension system for a front extension beam supported by a full-section anchor cable, comprising: multiple suspension units, each suspension unit being spaced apart and arranged along the roadway direction; each suspension unit bearing a front extension beam supported by a full-section anchor cable; each suspension unit including two suspension mechanisms, the two suspension mechanisms being respectively used to support the front end and rear end of the horizontally arranged front extension beam;

[0005] Each of the aforementioned suspension mechanisms includes:

[0006] The lifting ring fixing anchor is fixed to the lower end of the anchor cable that has already extended into the top rock layer of the roadway, and is located below the anchor cable pad and the anchor.

[0007] An arc-shaped ring, the opening of which is positioned facing the lifting ring fixing anchor and welded to the lifting ring fixing anchor;

[0008] Two horizontal load-bearing bars are set horizontally, with their front ends welded to both ends of the arc-shaped ring, and their rear ends extending horizontally.

[0009] Two vertical load-bearing rods are installed vertically, with their upper ends integrally connected to the rear ends of two horizontal load-bearing rods, and their lower ends extending downwards.

[0010] The lifting ring support rod is horizontally set, with its two ends integrally connected to the lower ends of two vertical support rods, and cooperates with the two vertical support rods to form a receiving area, so that the front end or rear end of the forward beam extends into the receiving area and is supported.

[0011] Furthermore, each suspension mechanism includes two reinforcing rods, which are inclined and whose two ends are fixedly connected to the corresponding horizontal force-bearing rod and vertical bearing rod, respectively.

[0012] A device for dismantling a suspension system for a full-section anchor cable-supported forward extension beam, comprising:

[0013] Handheld handle, vertically mounted;

[0014] The containment ring is a cavity with an opening at the top and a through hole at the bottom, through which the upper end of the handheld lever passes and enters the inner cavity of the containment ring;

[0015] The disassembly column is a cylindrical structure located inside the containment ring. Its upper end has a disassembly hole from top to bottom, and its lower end is integrally connected to the upper end of the hand handle. The disassembly hole is used for the lower end to extend into. The disassembly column is used to move upward after being pushed upward by the hand handle, thereby pushing the lifting ring fixing anchor upward and forcing the lifting ring fixing anchor to loosen the anchor cable, thereby removing the suspension mechanism.

[0016] The suspension system for the front extension beam supported by the full-section anchor cable is the aforementioned suspension system.

[0017] Furthermore, it also includes:

[0018] The upper disassembly rod is horizontally set along the direction of the tunnel. Its front end is fixedly connected to the side wall of the containment ring, and its rear end extends horizontally.

[0019] The support rod is horizontally set along the vertical aisle direction, and its middle part is fixedly connected to the middle part of the upper disassembly rod. It is used to support the lower side of the two horizontal force-bearing rods when disassembling the suspension mechanism.

[0020] The left disassembly rod is arc-shaped, with its front end fixedly connected to the side wall of the containment ring and its rear end bent to the left. It is used to pass through the containment area and lock into the rear end of the vertical support rod on the left side when disassembling the suspension mechanism.

[0021] The right dismantling rod is arc-shaped, with its front end fixedly connected to the side wall of the containment ring and its rear end bent to the right. It is used to pass through the containment area and lock into the rear end of the vertical support rod on the right side when dismantling the suspension mechanism. It is used in conjunction with the left dismantling rod and the upper dismantling rod to support the suspension mechanism after the lifting ring fixing anchor is removed from the dismantling column, so as to prevent the suspension mechanism from falling from the roof of the roadway.

[0022] Furthermore, it also includes:

[0023] The disassembly plate is vertically set, with its front side fixedly connected to the outer wall of the containment ring; its rear side is fixedly connected to the front ends of the upper disassembly rod, the left disassembly rod, and the right disassembly rod, respectively.

[0024] The beneficial effects of this utility model are:

[0025] The suspension system of this utility model can be directly fixed to the anchor cables that are already anchored to the roadway roof, thus eliminating the need to install anchor cables or anchor rods again; avoiding disturbance to the roadway roof, allowing the forward beam to be used normally, and ensuring safety during tunneling and maintenance;

[0026] The disassembly device of this utility model can quickly disassemble the suspension mechanism without requiring personnel to climb to the top of the tunnel. They only need to stand on the ground of the tunnel and use the disassembly column to apply an upward pushing force to the lifting ring fixing anchor. After the lifting ring fixing anchor is removed, the horizontal force-bearing rod and the vertical bearing rod are locked by the support rod, the left disassembly rod and the right disassembly rod to prevent the suspension mechanism from falling. This greatly improves the disassembly efficiency and reduces the risk of injury from disassembly. Attached Figure Description

The upper end of the disassembly column 18 has a disassembly hole from top to bottom, and the lower end of the disassembly column 18 is integrally connected to the upper end of the hand handle 16. The disassembly hole is used for the lower end of 24 to extend into. The disassembly column 18 is used to move upward after being pushed upward by the hand handle 16, thereby pushing the lifting ring fixing anchor 10 upward and forcing the lifting ring fixing anchor 10 to loosen the anchor cable 24, thereby removing the suspension mechanism.

[0045] The equipment for dismantling a suspension system for a full-section anchor cable support front beam also includes: an upper dismantling rod 19, a support rod 20, a left dismantling rod 21, and a right dismantling rod 22.

[0051] An installation method for a suspension system for a front-end beam supported by full-section anchor cables is as follows:

[0052] Multiple suspension units are arranged along the direction of the tunnel, and multiple suspension units are also arranged along the cross-section of the tunnel, such that the distance between two adjacent suspension units in the suspension units along the direction of the tunnel is less than the diameter of the log, and the distance between two suspension units set along the cross-section of the tunnel is less than the length of the log.

[0053] Then, the lifting ring fixing anchor 10 is fixed to the lower end of the anchor cable 24 that has been driven into the roadway roof. Then, the front end of the forward beam is extended into the accommodating area of ​​the suspension mechanism on the front side of the suspension unit, and the rear end of the forward beam is extended into the accommodating area of ​​the suspension mechanism on the rear side of the suspension unit, so that the forward beam is supported and held.

[0054] A method for dismantling equipment used in dismantling a suspension system for a full-section anchor cable-supported front extension beam is as follows:

[0055] The worker grasps the lower end of the handheld lever 16, bringing its upper end close to the suspension mechanism, and positions the support rod 20 against the lower sides of the two horizontal load-bearing rods 12. The left dismantling rod 21 passes through the receiving area and is engaged at the rear end of the left vertical support rod 13, while the right dismantling rod 22 passes through the receiving area and is engaged at the rear end of the right vertical support rod 13. The handheld lever 16 is then moved upwards, causing the lower end of the anchor cable 24 to extend into the dismantling hole of the dismantling post 18, with the upper end of the dismantling post 18 contacting the lower end of the lifting ring fixing anchor 10. At this point, the dismantling post 18 is forcefully pushed upwards using the handheld lever 16, forcing the lifting ring fixing anchor 10 to release the anchor cable 24 and quickly move downwards until the lifting ring fixing anchor 10 disengages from the anchor cable 24.

[0056] Example 1

[0057] Due to the unique characteristics of the surrounding rock in the No. 2 return airway of a certain mine's north wing, the use of anchor mesh support in some sections was insufficient, necessitating full-section anchor cable support. However, the mine was using temporary support consisting of forward-expanding beams in conjunction with individual anchors. The existing forward-expanding beam lifting rings could only be used on anchor bolts and were unsuitable for full anchor cable support. Consequently, the previously used forward-expanding beam lifting rings were inadequate, rendering the forward-expanding beams unusable. This resulted in inadequate support at the face after blasting or tunneling, leading to accidents involving falling rock and injuries to personnel during the installation of individual anchors.

[0058] Currently, we utilize scrap chisels, locks, and scrap steel pipes to process suspension systems, as well as equipment for processing and disassembling suspension mechanisms using scrap materials.

[0059] After a long period of use, it solved the problem that the front probe beam could not be used normally after blasting or tunneling when using pure anchor cable support in the No. 2 return airway of the North Wing, and also solved the problem of the danger of personnel working under the exposed roof. It greatly improved the safety of workers and created benefits for the safe development of the mine.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
