Description

Technical Field

[0001] This utility model belongs to the field of underground engineering technology, and specifically relates to a water supply and power supply device for a rock drilling rig and a rock drilling rig system. Background Technology

[0002] During tunnel face drilling and blasting operations using rock drilling rigs, it is usually necessary to connect external special water pipes and cables to cool the drill bit, reduce drill bit friction wear, remove cuttings and clean the blast holes, and provide working power for the hydraulic rock drill.

[0003] Before drilling operations can commence at the tunnel face, the drilling rig needs to deploy water pipes and cables via a reel to connect to water and electricity, increasing equipment deployment time. During operation, the water pipes and cables laid on the ground not only restrict the operation of other equipment inside the tunnel but are also susceptible to damage, posing additional construction risks. After drilling is completed, water and electricity must be cut off, and the water pipes and cables must be retracted before the rig can exit the working face. This process is slow, causing downtime for subsequent excavation equipment, reducing the speed of transitions between different tunnel operation procedures, increasing the time for each drilling and blasting cycle, and leading to increased costs and safety risks in mechanized tunnel construction. Utility Model Content

[0004] The purpose of this utility model is to address the problem that existing rock drilling rigs require the laying of water pipes and cables inside the tunnel to connect water and electricity during operation, which not only affects the efficiency of tunnel construction but also easily leads to safety risks inside the tunnel. This utility model provides a water and electricity supply device for a rock drilling rig and a rock drilling rig system.

[0013] Preferably, the magnetic hook includes a telescopic arm, one end of which has a magnetic attraction part, and the other end of which has a connecting part. The connecting part is detachably connected to the movable bracket, and the magnetic attraction part is used to attract the tail of the rock drilling rig.

[0014] Preferably, the magnetic attraction part includes a receiving shell and an electromagnet, the electromagnet is installed in the inner cavity of the receiving shell, and the iron core of the electromagnet extends from the side of the receiving shell away from the connecting part.

[0016] Preferably, the plurality of electromagnets are arranged at intervals along the length of the housing.

[0017] Preferably, the magnetic hook further includes an anti-detachment hook, which is installed on the telescopic arm and is disposed opposite to the magnetic part. The anti-detachment hook is used to connect with the rock drilling rig.

[0055] A water supply system 2 and a power supply system 3 are installed on the mobile bracket 1. The water supply system 2 provides working water to the rock drilling rig 5, and the power supply system 3 provides working electricity to the rock drilling rig 5. In use, the mobile bracket 1 is attached to the rear of the rock drilling rig 5 via a magnetic hook 4, thus allowing the mobile bracket 1 to move with the rock drilling rig 5. In this embodiment, the water supply and power supply devices achieve a detachable connection between the mobile bracket 1 and the rock drilling rig 5 by attaching the rock drilling rig 5 via the magnetic hook 4. Water system 2 and power supply system 3 supply water and power to the rock drilling rig 5, replacing the traditional method of connecting water and electricity externally through water pipes / cable discs. This enables the rapid deployment and withdrawal of the rock drilling rig 5 at the tunnel face without hindering the timely entry and use of rear equipment. Compared with traditional equipment construction, the water and power supply devices in this embodiment effectively improve the utilization efficiency of the tunnel rock drilling rig 5, making the drilling and blasting process transition more rapid, increasing the speed of mechanized tunnel construction, and avoiding the additional construction risks brought about by traditional water pipes and cables laid on the ground in the tunnel.

[0062] In one or more implementations, such as Figure 3As shown, the power supply system 3 includes a protective frame 31 and a battery pack 32. The protective frame 31 is connected to the movable bracket 1, and the battery pack 32 is located inside the protective frame 31. The battery pack 32 is used to supply power to the rock drilling rig 5.

[0063] Specifically, the protective frame 31 is connected to the chassis 11.

[0064] Furthermore, the protective frame 31 is a vibration filtering protective frame, the frame of which is made of metal or high-strength plastic, and a rubber pad is set inside the frame to buffer the battery pack 32.

[0065] In an optional embodiment, an electrical control box 33 is also included, with the battery pack 32 electrically connected to the electrical control box 33, and the electrical control box 33 supplies power to the rock drilling rig 5 via a cable 35.

[0066] Furthermore, a top plate 34 is provided on the top of the protective frame 31.

[0067] In one or more implementations, such as Figure 5 As shown, the magnetic hook 4 includes a telescopic arm 41, one end of which has a magnetic part 42, and the other end of which has a connecting part 43. The connecting part 43 is detachably connected to the movable bracket 1, and the magnetic part 42 is used to attract the tail of the rock drilling rig 5.

[0068] In an optional embodiment, the connecting part 43 is detachably connected to the end sleeve 13 of the movable bracket 1;

[0069] Specifically, such as Figure 4 , Figure 6 As shown, the connecting part 43 includes a bolt 431 and a nut 432 fixed to the end of the telescopic arm 41. When the magnetic hook 4 is connected to the movable bracket 1, the bolt 431 passes through the sleeve 13 and is fastened to the nut 432, thereby installing the magnetic hook 4 at the end of the movable bracket 1.

[0070] In optional implementations, such as Figure 7 As shown, the magnetic suction part 42 includes a housing 421 and an electromagnet 422. The electromagnet 422 is installed in the inner cavity of the housing 421, and the iron core 4221 of the electromagnet 422 extends from the side of the housing 421 away from the connecting part 43.

[0071] The housing 421 protects the electromagnet 422 from damage. The iron core of the electromagnet 422 extends from the side of the housing 421 away from the connecting part 43. The iron core 4221 of the electromagnet 422 attracts the metal shell at the rear of the rock drilling rig 5, thereby connecting the magnetic hook 4 to the rock drilling rig 5.

[0073] In an optional implementation, the electromagnet 422 is electrically connected to the power supply system 3.

[0074] The electromagnet 422 is powered by power supply system 3;

[0075] Furthermore, the electromagnet 422 is connected to the electrical control box 33 of the power supply system 3 via a wire. The electrical control box 33 controls the energization and de-energization of the electromagnet 422, thereby controlling the connection and separation of the magnetic hook 4 and the rock drilling rig.

[0076] In this application, electrical connection refers to the connection of two electrical components through a wire, that is, the electromagnet 422 is connected to the power supply system 3 through a wire.

[0077] In an optional embodiment, a plurality of electromagnets 422 are arranged at intervals along the length of the housing 421.

[0078] By setting multiple electromagnets 422, it is ensured that the magnetic hook 4 is firmly attached to the rock drilling rig 5, so that the connection between the magnetic hook 4 and the rock drilling rig 5 is stable.

[0079] In optional implementations, such as Figure 6 , Figure 7 As shown, the top surface of the housing 421 is provided with a first opening, which is connected to the inner cavity of the housing 421.

[0080] It also includes a cover plate 423, which is used to seal the first opening.

[0081] With the above settings, when it is necessary to replace the electromagnet 422, the electromagnet 422 in the inner cavity of the housing 421 can be replaced by opening the cover plate 423.

[0082] This embodiment also discloses the implementation steps of the water supply and power supply devices:

[0083] A1. The mobile bracket 1 is externally attached to the rear of the rock drilling rig 5 via the magnetic hook 4, and then the water supply system 2 and the power supply system 3 are matched with the rock drilling rig 5.

[0084] A2. Before starting work, the water supply and power supply devices of the rock drilling rig 5 should be filled with water and charged in advance to ensure the water and electricity storage capacity of the water supply and power supply devices.

[0085] A3. Before the rock drilling rig 5 enters the tunnel, check whether the water storage tank 22 and the battery pack 32 have sufficient power, and check whether the water pump 23 and the electrical control box 33 are functioning properly.

[0086] A4. The rock drilling rig 5 tows the mobile bracket 1 to the tunnel face. Alternatively, other vehicles can tow the mobile bracket 1 into position first. Then, the water pipe of the water supply system 2 and the cable of the power supply system 3 are connected to the rock drilling rig 5. Once the rock drilling rig 5 is ready, water and electricity are provided for the rock drilling operation through the water supply and power supply devices.

[0087] A5. After the drilling operation is completed, the mobile support 1 is towed away from the tunnel face by the rock drilling rig 5, and the water supply system 2 and the power supply system 3 are immediately replenished with water and charged to ensure the water and electricity reserves for the next cycle of operation.

[0088] Example 2

[0089] Based on Example 1, such as Figure 5 , Figure 7 As shown, the magnetic hook 4 also includes an anti-detachment hook 44, which is installed on the telescopic arm 41 and is arranged opposite to the magnetic part 42. The anti-detachment hook 44 is used to connect with the rock drilling rig 5.

[0090] The magnetic suction part 42 is installed on the top surface of the telescopic arm 41, and the anti-disengagement hook 44 is installed on the bottom surface of the telescopic arm 41.

[0091] When the road conditions inside the tunnel are poor and the moving bracket 1 experiences significant bumps when passing through, the anti-detachment hook 44 is connected to the rock drilling rig 5. When the magnetic suction part 42 accidentally separates from the rock drilling rig 5 on a bumpy section, the connection between the anti-detachment hook 44 and the rock drilling rig 5 prevents the magnetic suction hook 4 from detaching from the rock drilling rig 5.

[0092] Furthermore, such as Figure 6 As shown, it also includes a vertical shaft 45, which is vertically set on the bottom surface of one end of the telescopic arm 41 near the magnetic suction part 42. The anti-disengagement hook 44 is rotatably connected to the vertical shaft 45 so that the anti-disengagement hook 44 can rotate around the vertical shaft 45. When the anti-disengagement hook 44 needs to be connected to the rock drilling rig 5, the anti-disengagement hook 44 can be rotated out from under the magnetic suction part 42.

[0093] Example 3

[0094] Based on Example 1, such as Figures 1-3 As shown, this embodiment discloses a rock drilling rig system, including a rock drilling rig 5 and a water supply and power supply device for the rock drilling rig as described in Embodiment 1. The movable bracket 1 is connected to the rear of the rock drilling rig 5 by a magnetic hook 4. The water supply system 2 supplies water to the rock drilling rig 5, and the power supply system 3 supplies power to the rock drilling rig 5.

[0095] The rock drilling rig system of this embodiment includes a rock drilling rig 5 equipped with a water supply system 2 and a power supply system 3. It can be quickly deployed at the tunnel face. When the rock drilling rig starts drilling operations, the water supply system 2 and the power supply system 3 provide working water and electricity immediately. When drilling operations are completed, the water supply system 2 and the power supply system 3 can be quickly withdrawn from the tunnel face along with the rock drilling rig 5, making the transition between drilling and blasting operations faster and improving the speed of mechanized tunnel construction. It is suitable for mechanized tunnel construction and has good prospects for widespread application.

[0096] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
