Description

Technical Field

[0001] This utility model relates to the field of pipe joint anchor technology, and in particular to an automated feeding device for pipe joint anchors. Background Technology

[0002] In the excavation of underground mine roadways and tunnel construction, rock bolt support is a core process to ensure the stability of the surrounding rock and prevent roof collapse and sidewall spalling accidents. Among them, slotted pipe rock bolts are widely used in geotechnical engineering support due to their characteristics of full-length anchoring, convenient installation and high initial anchoring force. At present, rock bolt support operations are usually completed by rock bolt drilling rigs or integrated rock drill and anchor machines. The standard operating procedure includes positioning, drilling, installing rock bolts and fastening the tray. In conventional mechanized operations, the propulsion beam on the drill arm is responsible for providing the thrust and impact force required for drilling and rock bolt installation by the rock drill to realize the mechanization of the support process.

[0003] However, existing pipe joint anchor construction still has problems. Although drilling and pushing have been mechanized, the loading of anchors still mostly relies on manual labor to place the anchors on the pusher or the drill bit holder. Since pipe joint anchors are heavy and long, this method is not only labor-intensive, but also forces operators to work under the unsupported roof area, resulting in significant safety hazards. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art mentioned above, and to propose an automated feeding device for pipe joint anchor bolts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated feeding device for pipe joint anchor bolts includes a feeding box, the inside of which is provided with a storage slot, and vertical slots are provided on both the front and rear sides of the inside of the feeding box. A slider is slidably connected inside the storage slot, and a rubber pad is fixedly connected to the top of the slider.

[0007] Preferably, the feeding box body has inner grooves on both the left and right sides of the storage groove, and a buffer device is provided inside the inner groove. The buffer device is composed of a buffer plate and a buffer spring that are rotatably connected inside the inner groove.

[0008] Preferably, a fixing rod is fixedly installed on both sides of the top of the feeding box, and a rodless cylinder is fixedly installed on the top wall of the fixing rod, with the output end of the rodless cylinder fixedly connected to the slider.

[0009] Preferably, a pressing block is fixedly installed at the bottom end of the slider, a protective device is fixedly installed on the bottom wall of the feeding box, and a contact is fixedly installed on the bottom wall of the feeding box. The protective device is a combination of a spring and a pressing plate at the top, and the contact is located directly below the protective device.

[0010] Preferably, the pressing block is located directly above the protective device.

[0011] Preferably, the top side wall of the feeding box is provided with a feeding port, and baffles are rotatably connected to the upper and lower sides inside the feeding port. Electromagnetic blocks are fixedly installed inside the near ends of the two baffles, and the near ends of the two electromagnetic blocks are opposite magnetic poles.

[0012] Preferably, storage racks are rotatably connected to both sides of the top of the feeding box, and a pressure spring is fixedly connected between the storage racks and the top of the feeding box. The storage racks are in the shape of an inverted "L".

[0013] Compared with the prior art, this utility model provides an automated feeding device for pipe-slot anchor bolts, which has the following beneficial effects:

[0014] 1. The automated feeding device for the pipe joint anchor rod, by setting a contact at the bottom to form a signal linkage with the electromagnetic block at the feed inlet, can accurately identify the reset state of the slider; only when the slider is fully reset and the contact is triggered can the baffle at the feed inlet be opened to replenish material, thereby effectively preventing mechanical interference or jamming accidents caused by external anchor rods accidentally entering the storage tank during the upward pushing of the slider, thus eliminating safety hazards at the source.

[0015] 2. The automated feeding device for the pipe joint anchor bolt utilizes the elastic abutment structure of the buffer device. On the one hand, it can eliminate the gap between the anchor bolt and the box during standby or movement, avoiding the harsh noise caused by rigid collision. On the other hand, the buffer plate can buffer the descending anchor bolt, avoiding collision caused by the anchor bolt descending too fast, thus ensuring smooth feeding. Attached Figure Description

[0025] Reference Figures 1-4 An automated feeding device for slotted pipe anchor bolts includes a feeding box 1, which is a vertically arranged hollow cuboid structure, preferably made of high-strength manganese steel to withstand the harsh underground environment. The feeding box 1 has a storage slot 2 inside, the cross-sectional shape of which matches the contour of the slotted pipe anchor bolt. Vertical slots 3 are provided on both the front and rear sides of the feeding box 1, extending through the upper and lower ends of the feeding box 1 as power transmission channels. A slider 8 is slidably connected inside the storage slot 2, and a rubber pad 9 is fixedly connected to the top of the slider 8. The top of the rubber pad 9 has an anti-slip texture that matches the shape of the bottom of the slotted pipe anchor bolt, and the rubber pad 9 is connected to the slider 8 with strong adhesive to prevent it from falling off due to prolonged pushing operations.

[0026] Reference Figures 2-3The feeding box 1 has inner grooves 4 on both the left and right sides of the storage groove 2. The inner groove 4 is equipped with a buffer device 5. The buffer device 5 is composed of a buffer plate and a buffer spring that are rotatably connected inside the inner groove 4. The buffer plate is hinged to the upper end of the inner groove 4 by a pin. One end of the buffer spring abuts against the bottom of the inner groove 4 and the other end abuts against the surface of the buffer plate. The buffer plate can be rotated into the inner groove 4.

[0027] Reference Figures 2-4 Fixed rods 6 are fixedly installed on both sides of the top of the feeding box 1. Rodless cylinders 7 are fixedly installed on the top wall of the fixed rods 6. Rodless cylinders 7 are vertically installed by bolt fastening and their stroke length is greater than the effective depth of the storage groove 2. The output end of rodless cylinder 7 is fixedly connected to slider 8. Pressing block 10 is fixedly installed at the bottom end of slider 8. Protective device 11 is fixedly installed on the bottom wall of feeding box 1. Contact 12 is fixedly installed on the bottom wall of feeding box 1. Protective device 11 is composed of a spring and a pressing plate at the top. Contact 12 is located directly below protective device 11. Contact 12 is a limit switch and its signal output end is electrically connected to the input end of the control system. Pressing block 10 is located directly above protective device 11.

[0028] Reference Figures 5-6 The top side wall of the feeding box 1 is provided with a feeding port 13. The edge of the feeding port 13 is provided with an inwardly inclined guide slope to facilitate the introduction of the pipe seam anchor rod. The upper and lower sides of the inside of the feeding port 13 are rotatably connected with baffles 14. The baffles 14 are installed on the inner wall of the feeding port 13 through a rotating shaft. The free end of the baffle 14 forms a wedge-shaped structure that retracts into the storage tank 2 when closed. This structure enables the baffles 14 to have a one-way opening function. Electromagnetic blocks 15 are fixedly installed inside the close ends of the two baffles 14. The close ends of the two electromagnetic blocks 15 are opposite magnetic poles. The electromagnetic blocks 15 are embedded in the inside of the baffles 14 and are covered with a non-magnetic protective layer to prevent the pipe seam anchor rod from directly impacting and damaging the electromagnetic components.

[0029] Reference Figures 1-2 Storage racks 16 are rotatably connected to both sides of the top of the feeding box 1. A pressure spring 17 is fixedly connected between the storage rack 16 and the top of the feeding box 1. The storage rack 16 is in the shape of a flipped "L".

[0030] In this invention, in the initial state or during the replenishment of pipe seam anchors, the device first aligns the pipe seam anchor with the feed inlet 13 on the side wall of the feeding box 1 via an external conveying mechanism or manually. Simultaneously, the control system adjusts the electromagnetic blocks 15 located within the upper and lower baffles 14 inside the feed inlet 13 to generate magnetic repulsion, eliminating the attraction between the baffles and allowing the two baffles 14 to be in a free state that can be pushed open, thus allowing the pipe seam anchor to enter the storage tank 2 laterally. Initially, the buffer plate of the buffer device 5 is perpendicular to the inner wall of the storage tank 2, because... The anchor rods falling into the storage tank 2 through the feed inlet 13 will first contact the buffer plate. At this time, the buffer plate will rotate against the elastic force of the buffer spring and move into the inner tank 4. Then the anchor rods will continue to move downwards until they contact the rubber pad. At this time, the pipe joint anchor rods in the storage tank 2 are arranged vertically and neatly. At the same time, the buffer device 5 located inside the inner tank 4, under the elastic force of the buffer spring, continues to press against the side wall of the pipe joint anchor rod, thereby eliminating the gap between the anchor rod and the box body and preventing rigid collision noise generated during the operation of the traction vehicle. At this time, the standby preparation is completed.

[0031] When drilling is completed and anchor bolt installation is required, the system issues a loading command, activating the rodless cylinder 7 mounted on the top wall of the fixed rod 6. The output end of the rodless cylinder 7 drives the slider 8 to slide upwards within the vertical groove 3. The rubber pad 9, fixedly connected to the top of the slider 8, moves upwards and flexibly contacts the bottom of the bottom pipe joint anchor bolt. The high coefficient of friction of the rubber pad 9 ensures the stability of the contact surface and avoids hard slippage between metals. As the slider 8 continues to move upwards, the entire row of pipe joint anchor bolts in the storage groove 2 is pushed upwards synchronously. When the topmost pipe joint anchor bolt is pushed to the top outlet of the loading box 1, the anchor bolt continues to move upwards and passes through the gap between the two storage racks 16, finally positioning itself in the top area between the two storage racks 16. This position allows the anchor bolt to smoothly transition to the drilling machine's gripping mechanism or align with the center of the borehole, facilitating subsequent installation. Then, the anchor bolt can be pushed axially by the propulsion equipment and driven into the borehole, thus completing a single loading operation.

[0032] If further feeding is required, simply drive the rodless cylinder 7 again to move the slider 8 upward, pushing the next anchor rod to the predetermined position for feeding. This process is repeated to achieve automatic feeding. When all the anchor rods inside the feeding box 1 are consumed, the system drives the rodless cylinder 7 to move the slider 8 downward to reset, causing the slider 8 to move the pressing block 10 downward. During this process, the pressing block 10 will first contact the pressing plate at the top of the protective device 11, causing the spring inside the protective device 11 to be compressed. This physically buffers and absorbs the inertial impact force of the slider 8 moving downward, preventing the slider from directly hitting the box. The bottom will not cause mechanical damage; as the pressing block 10 continues to press down, when it reaches the preset position, it will trigger the contact 12 located directly below the protective device 11; the contact 12, as a limit sensor, will feed the signal back to the control system to confirm that the slider 8 has been completely reset to zero; after receiving the reset signal, the system controls the two electromagnetic blocks 15 electrically connected to them to generate a repulsive effect again, allowing the two closed baffles 14 to be opened again for material replenishment; this interlocking mechanism effectively avoids mechanical interference caused by the anchor rod entering through the feed port 13 during the upward movement of the slider 8 inside the storage tank 2, thereby eliminating safety hazards.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
