Description

Technical Field

[0001] This utility model relates to the field of cable support technology, specifically to a heavy-duty cable support for a rock drilling rig. Background Technology

[0002] A rock drilling rig is a type of rock drilling equipment used in tunnel and underground engineering projects employing the drill-and-blast method. It can move and support multiple rock drills to perform drilling operations simultaneously. When operating in mines and tunnels, the rock drilling rig needs to be connected to external equipment via long and heavy-duty cables to transmit power and signals. However, due to the complex environment inside mines and tunnels, and the presence of other operating vehicles, these heavy-duty cables are prone to being crushed or contaminated by mud, causing wear and tear, reducing their lifespan, and in severe cases, increasing the risk of electric shock.

[0003] CN210806608U discloses a portable temporary cable support, including a support rod with a rigid tube sleeved on its surface. Support mechanisms are fixedly installed at both ends of the support rod to support the cable. However, the above solution has the following technical problems: 1. The support mechanism is a tripod, which is difficult to store and occupies a large amount of space; 2. Because the drilling rig changes its drilling position during operation, the cable is pulled and can easily slip off both ends of the support rod. Utility Model Content

[0004] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes a heavy-duty cable support for rock drilling rigs, which can prevent the cable from slipping off both sides to a certain extent, has high support strength, can be folded and retracted, and is convenient for storage and transportation.

[0005] To achieve the above objectives, this utility model provides a heavy-duty cable support for a rock drilling rig, comprising a scissor-type structure spaced apart at the front and rear. The hinge axes of the two scissor-type structures are on the same straight line, and the two scissor-type structures are horizontally connected by crossbeams at their four ends to form a folding support. The two top crossbeams are used to lay the heavy-duty cable of the rock drilling rig. Both the scissor-type structures and the crossbeams are made of high-strength materials. Insulating sleeves are fitted over the two top crossbeams, and both ends of the insulating sleeves abut against the scissor-type structures. The portion of the scissor-type structure above the crossbeams is also wrapped with an insulating layer. A limiting rope for limiting the maximum unfolding angle of the scissor-type structure is connected between the two bottom crossbeams. Pressure plates are provided at the bottom ends of the legs of the scissor-type structure, and the pressure plates are used for pressing down with stones or counterweights.

[0006] In the above scheme: the bottom end of the support leg is provided with a retractable ground nail for insertion into the ground; the support leg is provided with a receiving groove for accommodating the ground nail; the bottom of the receiving groove is provided with a first compression spring for pushing out the ground nail; a locking pin is horizontally provided on one side of the ground nail; a receiving cavity is provided inside the ground nail for accommodating the locking pin; a second compression spring for pushing out the locking pin is connected between the locking pin and the side wall of the receiving cavity; the ground nail is provided with a through hole for the head of the locking pin to extend out; the tail of the locking pin is provided with an anti-detachment end that is always slidably connected in the receiving cavity; and the bottom of the support leg is provided with an extension locking hole for the locking pin to pass through.

[0007] In the above solution, a storage lock hole is provided on the part of the outrigger corresponding to the ground stake that can be completely retracted into the receiving groove. This allows the ground stake to be locked in its retracted state, reducing storage space and facilitating the erection of supports on hardened ground.

[0008] In the above design, the pressure plate extends to the left and right sides, and the locking pins of the same scissor-type structure are positioned to the front and rear sides respectively. This prevents the ground stakes from retracting due to stones or other counterweights pressing on the locking pins, thus improving the stability of the support.

[0009] In the above scheme: the insulating sleeve is equipped with a fixing rope for fixing the cable. The heavy cable is tied to the insulating sleeve by the fixing rope to prevent the rock drilling rig from falling or sliding during operation, and to further improve the support stability of the heavy cable.

[0010] In the above solution, the scissor-lift structure is also equipped with reflective markings. This improves visual visibility, serves as a clear warning to surrounding personnel, and reduces safety hazards such as accidental contact and misoperation, making it particularly suitable for complex or densely populated work environments.

[0011] In the above solution: the limiting rope is a metal chain, which improves the connection strength and prevents breakage.

[0012] In summary, the beneficial effects of this utility model are:

[0013] 1. The folding structure is formed by two scissor-type structures, making it convenient for storage and transportation; the folding design allows it to be folded up when not in use, greatly saving storage space; it is also easier to carry during transportation, reducing logistics and warehousing costs and improving portability;

[0014] 2. The scissor-type structure can be made of high-strength materials such as metal, with high load-bearing capacity, strong durability, and a stable overall structure. It can effectively bear the weight load of heavy cables, is not easily deformed or damaged, has a long service life, and can stably support heavy cables for a long time.

[0015] 3. The top of the scissor-type structure can be used as a stop to prevent the cable from slipping off the sides of the support. Combined with the fixing rope on the insulating sleeve, the cable is reliably fixed. It can limit and fix the laid cable, prevent the cable from slipping or shifting during use, and ensure the stability and neatness of the heavy cable laying.

[0016] 4. The insulating sleeve and insulating layer can form an insulating structure between the bracket and the cable, improving safety. At the same time, the bracket can also be made of metal, increasing the range of materials that can be selected to meet the support requirements of heavy-duty cables.

[0017] 5. Simple operation and wide adaptability to various scenarios: The unfolding and storage process does not require complicated tools and can be completed quickly; the structural design can adapt to various cable laying scenarios (such as cable layout requirements of different lengths and quantities, and different ground scenarios), which is highly practical and convenient for flexible on-site layout.

[0022] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0023] like Figures 1-4 As shown, a heavy-duty cable support for a rock drilling rig includes scissor-type structures 1 spaced apart at the front and rear. The hinge axes of the two scissor-type structures 1 are on the same straight line, and horizontal beams 5 extending forward and backward are horizontally connected to the four ends of each of the two scissor-type structures 1. The rods of the scissor-type structures 1 on both sides and the horizontal beams 5 extend upward and downward to form a support frame, creating an X-shaped folding structure. The two top horizontal beams 5 are used to lay the heavy-duty cable of the rock drilling rig, and the two top horizontal beams 5 are covered with insulating sleeves 3 made of insulating material. The insulating sleeves 3 are rotatably fitted onto the horizontal beams 5, and the two ends of the insulating sleeves 3 abut against the scissor-type structures 1. The portion of the scissor-type structure 1 above the horizontal beams 5 is also covered with an insulating layer 2 to prevent the heavy-duty cable from slipping through the top of the scissor-type structure 1. The insulating sleeve 3 is equipped with a fixing rope 4 for fixing the cable. After the cable is laid, the heavy cable can be tied to the insulating sleeve 3 by the fixing rope 4 to prevent the rock drilling rig from falling or sliding during operation, and further improve the support stability of the heavy cable.

[0024] A limiting rope 6, made of metal chain, is connected between the two bottom crossbeams 5 to restrict the maximum deployment angle of the scissor lift structure 1, thereby increasing its strength. The scissor lift structure 1 is constructed entirely of square steel pipes, which enhances its support strength.

[0025] The bottom end of each leg of the scissor-type structure is equipped with a pressure plate 7, which is used to hold down the support with stones or counterweights to prevent it from falling over. The pressure plate 7 extends to the left and right and outwards. Each leg has a ground nail 10 inserted into the ground at its bottom end. A receiving groove 14 for accommodating the ground nail 10 is provided on the leg; in this embodiment, it is directly accommodated by a hollow structure of a square steel tube. A first compression spring 11 for pushing out the ground nail 10 is provided at the bottom of the receiving groove 14. In this embodiment, a horizontal plate is welded inside the square steel tube to serve as the bottom of the receiving groove 14. A locking pin 9 is horizontally provided on one side of the ground nail 10. A receiving cavity for accommodating the locking pin 9 is provided inside the ground nail 10. A second compression spring 12 for pushing out the locking pin 9 is connected between the locking pin 9 and the side wall of the receiving cavity. The locking pin 9 is slidably connected within the receiving cavity, and a through hole is provided on the ground nail 10 for the end of the locking pin 9 to extend out. In this embodiment, the ground stake 10 is also a hollow structure, and the top of the ground stake 10 is closed. A horizontal plate located below the through hole is welded inside the ground stake 10, forming the receiving cavity between the horizontal plate and the top of the ground stake 10. The head of the locking pin 9 extends out of the through hole to the outside of the ground stake 10, and the tail is provided with an anti-detachment end that is larger than the through hole. The top and bottom of the anti-detachment end abut against the top of the ground stake 10 and the horizontal plate, respectively, so that the anti-detachment end is always slidably connected in the receiving cavity.

[0026] The bottom of the outrigger has an extension locking hole 8 through which the locking pin 9 passes, thereby locking the ground stake 10 in the extended state. Above the extension locking hole 8 is a storage locking hole 13, and when the locking pin 9 is inserted into the storage locking hole 13, the ground stake 10 can be completely stored in the outrigger of the scissor-type structure 1.

[0027] Locking pins 9 on the same scissor structure 1 are respectively set on the front and rear sides, and on the side away from the other side of the rod.

[0028] The pole is also equipped with reflective markings. In this embodiment, the reflective markings are red and white warning stripes, which improve visual recognition and can play a clear warning role to people in the surrounding area, reducing safety hazards such as accidental contact and misoperation. It is especially suitable for complex or densely populated work scenarios.

[0029] Meanwhile, the dimensions of each component of the support are manufactured according to strict tolerance ranges (such as ±0.50), ensuring high machining and assembly precision. This ensures that the structure is stable after the support is deployed, and it is not easy to shake or deform during use, further improving the reliability of the support.

[0030] When in use, the support frame is opened to the extended position. If the construction site is not a hardened surface such as cement, the ground nails 10 are extended and the pressure plate 7 is stepped on to insert the ground nails 10 into the ground, thereby improving the grip. Then, heavy objects such as stones are placed on the pressure plate 7 to further prevent tilting and improve the stability of the support frame.

[0031] If the construction site has hardened ground or a lot of rocks, and the ground nail 10 cannot be inserted, the ground nail 10 can be retracted and stored in a stowed state. Then, heavy objects such as stones can be used to press it onto the pressure plate 7 to improve the stability of the support.

[0032] After all the supports are erected, heavy-duty cables are laid and secured to the supports with fixing ropes 4 to prevent the rock drilling rig from falling or slipping during operation. After the operation is completed, the ground stakes 10 can be retracted and the scissor mechanism 1 can be closed, saving storage space, making it easy to carry, reducing logistics and warehousing costs, and improving portability.
