Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunneling drilling rig technology, and in particular to a stabilizing device for a tunneling drilling rig used in mining operations. Background Technology
[0002] In modern mining operations, tunneling drilling rigs are key equipment, undertaking the important task of drilling holes in ore and rock. The accuracy and stability of their drilling directly affect blasting effects, mining efficiency, and construction safety.
[0003] Existing tunneling drilling rigs typically employ a boom structure to support the drill rod sleeve during drilling operations, enabling drilling at varying angles and depths. However, this boom has a significant overhang length during operation, making it difficult to maintain drill bit stability. When the drill bit contacts the ore and generates impact and vibration, the boom's overhang amplifies these external forces, causing significant drill bit swaying. This swaying not only reduces drilling accuracy, causing hole position deviation and increased hole diameter errors, affecting the quality of subsequent blasting and mining operations, but can also lead to equipment damage such as drill rod breakage and accelerated drill bit wear, increasing equipment maintenance costs and downtime. Furthermore, drill bit swaying poses safety hazards, potentially causing injuries to operators. Therefore, there is an urgent need to design an effective stabilization device to solve the drill bit swaying problem caused by the boom overhang of tunneling drilling rigs, thereby improving the safety and efficiency of mining operations. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stabilizing device for mining tunneling drilling rigs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A stabilizing device for a mining tunneling drill rig includes a drill rod sleeve. An external mechanism is provided on the outer wall of the drill rod sleeve. The external mechanism includes a fixing component and a stabilizing component. The fixing component includes two symmetrically arranged semi-circular rings, and the stabilizing component includes two symmetrically arranged structural semi-arc plates. A laser ranging probe is fixedly installed on the side of each semi-circular ring. Several sliding rods are fixedly installed at the bottom of each structural semi-arc plate. Compression springs are sleeved on the outer walls of the sliding rods. A rubber abutment plate is screwed onto the upper side of each structural semi-arc plate. Several internal grooves are formed on the upper side of the rubber abutment plate, and connecting bolts are screwed onto the inner sides of the internal grooves.
[0007] Furthermore, several protective sleeves are fixedly installed on the semi-circular ring, and the sliding rod is slidably inserted into the inner side of the protective sleeve.
[0008] By adopting the above technical solution, the protective sleeve provides a stabilizing effect for the sliding guide of the slide rod.
[0009] Furthermore, a limit nut is screwed onto the end of the slide rod.
[0010] Furthermore, a sealing corrugated sleeve is provided on the outer side of the compression spring, and the inner wall of the sealing corrugated sleeve does not contact the outer side of the compression spring.
[0011] By adopting the above technical solution, the sealed corrugated sleeve can provide protection for the compression spring and prevent dust from entering the interior during drilling and affecting the compression spring.
[0012] Furthermore, a connecting cable is electrically connected to the side wall of the semi-circular ring, and the connecting cable is electrically connected to the laser ranging probe.
[0013] Furthermore, the two sides of the semi-circular ring are symmetrically fixedly connected with mating plates, and mating bolts are screwed between the two mating plates.
[0014] By adopting the above technical solution, the two semi-clamps are fixed to the outer wall of the drill rod sleeve of the drilling rig by means of screw clamps, which is convenient for installation and easy for disassembly and maintenance in the future.
[0015] Furthermore, an inner groove is provided on the inner side of the semi-circular ring, and a rubber gasket is embedded in the inner side of the inner groove.
[0016] Furthermore, the inner surface of the rubber pad is provided with several protrusions evenly distributed.
[0017] By adopting the above technical solution, the setting of several protrusions greatly improves the roughness of the inner surface of the rubber gasket, so that when the two semi-engraved ring screws are engaged on the outer wall of the drill rod sleeve of the drilling rig, the rubber gasket abuts against the outer wall of the drill rod sleeve of the drilling rig, thereby making the entire fixing assembly firmly fixed on the outer wall of the drill rod sleeve of the drilling rig and not easy to slip.
[0018] Furthermore, the two semi-clamping rings are screwed together on the outer wall of the drill rod sleeve of the mining drilling rig, and the semi-clamping rings, the structural semi-arc plate and the slide rod are all made of high-strength stainless steel.
[0019] Furthermore, a drill core is rotatably installed inside the drill rod sleeve of the mining drilling rig.
[0020] By adopting the above technical solution, the drill pipe sleeve of the mining tunneling drilling rig provides protection for the internal drill core.
[0021] Compared with related technologies, the stabilization device for a mining tunneling drilling rig proposed in this utility model has the following beneficial effects:
[0022] In this utility model, a stabilizing device for a mining tunneling drill rig is fixed to the outer wall of the drill rod sleeve of the mining tunneling drill rig by means of a screw-on clamping mechanism. As an external component, it can be added later as needed, is convenient to use, has a compact structure, low production cost, and strong practicality. In the external mechanism, the rebound force of the compression spring drives the structural semi-arc plate to abut against the drill hole rock wall. During core drilling, the friction of the rubber abutment plate provides lateral support stability, reduces shaking during core drilling, and improves drilling stability. Furthermore, as the drilling depth increases, the distance between the structural semi-arc plate and the semi-clamping ring gradually decreases. A laser rangefinder is used to detect the distance between the structural semi-arc plate and the semi-clamping ring, and the decrease in distance directly reflects the drilling depth, providing an accurate drilling depth value for the drilling operation.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0032] Reference Figures 1-7 A stabilizing device for a mining tunneling drill rig includes a drill rod sleeve 1, a drill core 11 rotatably mounted inside the drill rod sleeve 1, and an external attachment mechanism 2 on the outer wall of the drill rod sleeve 1. The external attachment mechanism 2 includes a fixing component 3 and a stabilizing component 4. The fixing component 3 includes two symmetrically arranged semi-circular rings 31, and the stabilizing component 4 includes two symmetrically arranged structural semi-arc plates 41. A laser ranging probe 38 is fixedly mounted on the side of the semi-circular rings 31. Several sliding rods 42 are fixedly mounted on the bottom of the structural semi-arc plates 41. Compression springs 43 are sleeved on the outer wall of the sliding rods 42. A rubber abutment plate 46 is screwed onto the upper side of the structural semi-arc plates 41. Several inner grooves 47 are opened on the upper side of the rubber abutment plate 46, and connecting bolts 48 are screwed onto the inner side of the inner grooves 47.
[0033] In this embodiment, a plurality of protective sleeves 32 are fixedly installed on the semi-circular ring 31, and the sliding rod 42 is slidably inserted into the inner side of the protective sleeve 32. The end of the sliding rod 42 is screwed with a limit nut 44.
[0034] Through the above structure, the casing 32 provides sliding guidance for the slide rod 42. During drilling, as the drill rod sleeve 1 and its inner drill core 11 of the mining tunneling drill rig are gradually advanced, the rock wall will push the structural semi-arc plate 41 to drive the slide rod to slide out of the casing 32, so that the compression amount of the compression spring 43 gradually increases, and thus the abutment pressure provided by the compression spring 43 to the structural semi-arc plate 41 gradually increases. This gradually strengthens the lateral support provided by the entire stabilizing component to the outside of the drill rod sleeve 1 of the mining tunneling drill rig, improving the stability during drilling. The laser ranging probe 38 detects the distance between the structural semi-arc plate 41 and the semi-clamping ring 31 in real time and transmits the data to the vehicle system of the mining tunneling drill rig through the connecting cable 39. The vehicle system calculates the drilling depth, and thus the drilling depth can be monitored in real time.
[0035] It should be noted that mining drilling rigs are common equipment and will not be described in detail here.
[0036] In this embodiment, a sealing corrugated sleeve 45 is provided on the outer side of the compression spring 43, and the inner wall of the sealing corrugated sleeve 45 does not contact the outer side of the compression spring 43.
[0037] Through the above structure, the sealed bellows sleeve 45 provides protection for the compression spring 43.
[0038] In this embodiment, a connecting cable 39 is electrically connected to the side wall of the semi-circular ring 31, and the connecting cable 39 is electrically connected to the laser ranging probe 38.
[0039] With the above structure, after the device is fixedly installed, the connecting cable 39 is electrically connected to the mining drilling rig.
[0040] In this embodiment, the two sides of the semi-circular ring 31 are symmetrically fixedly connected with mating plates 36, and the two mating plates 36 are screwed together with mating bolts 37. The inner side of the semi-circular ring 31 is provided with an inner groove 33, and a rubber gasket 34 is embedded in the inner side of the inner groove 33. Several protrusions 35 are evenly distributed on the inner side of the rubber gasket 34.
[0041] With the above structure, the surface roughness of the rubber pad 34 is relatively high, so when its inner side abuts against the outer wall of the drill rod sleeve 1 of the mining drilling rig, it can provide a stable friction force, so that the entire fixing assembly 3 can be stably and securely installed on the outer wall of the drill rod sleeve 1 of the mining drilling rig.
[0042] In this embodiment, two semi-circular rings 31 are screwed together on the outer wall of the drill rod sleeve 1 of the mining drilling rig. The semi-circular rings 31, the structural semi-arc plate 41, and the slide rod 42 are all made of high-strength stainless steel.
[0043] The above structure ensures the structural strength of the main components, provides stable support, and is corrosion-resistant, thus extending their service life.
[0044] In this utility model, during use:
[0045] Before the stabilization device of the tunneling drill is put into use during mining operations, two semi-circular rings 31 are first wrapped around the outer wall of the drill rod sleeve 1 of the tunneling drill. The semi-circular rings 31 are then screwed together and fixed using the connecting plate 36 and connecting bolts 37. The rubber gasket 34 in the inner groove 33 of the inner side of the semi-circular ring 31, with its surface protrusion 35, tightly abuts against the outer wall of the drill rod sleeve 1 of the tunneling drill, generating a large frictional force to ensure that the fixing component 3 is firmly installed on the drill rod sleeve 1 of the tunneling drill. At the same time, the connecting cable 39 on the side wall of the semi-circular ring 31 is connected to the tunneling drill, so that the laser ranging probe 38 can work normally.
[0046] When the tunneling drill starts operating, the drill core 11 rotates inside the drill rod sleeve 1 of the mining tunneling drill and advances to drill a hole. During the drilling process, the rock wall will exert a reverse force on the stabilizing component 4, pushing the structural semi-arc plate 41 to drive the slide rod 42 to slide along the casing 32, so that the compression spring 43 sleeved on the slide rod 42 is gradually compressed. As the drilling progresses, the compression amount of the compression spring 43 continues to increase, and its rebound force also gradually increases, thereby driving the rubber abutment plate 46 on the structural semi-arc plate 41 to press tightly against the drill hole rock wall. The rubber abutment plate 46 provides strong lateral support for the drill rod sleeve 1 of the mining tunneling drill by its own friction, effectively reducing the shaking of the drill core 11 during drilling, improving drilling stability and accuracy, reducing the risk of equipment damage, and ensuring construction safety.
[0047] Meanwhile, the laser ranging probe 38 detects the distance between the semi-arc plate 41 and the semi-clamping ring 31 in real time. As the drilling depth increases, the distance between the semi-arc plate 41 and the semi-clamping ring 31 gradually decreases. The laser ranging probe 38 transmits the detected distance data to the vehicle system of the mining tunneling drilling rig through the connecting cable 39. The vehicle system accurately calculates the current drilling depth based on the decrease in distance, providing accurate data support for drilling operations, enabling operators to keep abreast of the drilling progress and make reasonable arrangements for subsequent work.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
