Description

Technical Field

[0001] This utility model relates to the field of support construction technology, specifically a mobile side reinforcement support machine. Background Technology

[0002] Side reinforcement support is an important technical means in the maintenance of coal mine roadways. It is mainly used to enhance the stability of the side walls on both sides of the roadway and prevent side spalling or deformation. High-strength anchor bolts are usually used in conjunction with protective nets to reinforce the side walls of the roadway. When performing side reinforcement support on coal mine roadways, a two-arm anchor bolting machine is usually used to drive anchor bolts into the upper and lower parts of the support and fix the side anchor cables.

[0003] A search revealed a patent application with application number 201911337319.2 that discloses a two-arm anchor bolt drilling rig, including a chassis assembly, a rear frame assembly, a temporary support structure, a left swing arm, and a right swing arm. The rear frame assembly is located on the left side of the chassis assembly. A driving control system, a hydraulic system, an electrical system, and a water-cooled dust removal system are installed on the rear frame assembly. A cable winding device is installed inside the rear frame assembly. The left and right swing arms are mounted on the chassis assembly via a hydraulic rotary table. Drill frame assemblies are installed on both the left and right swing arms. A cover assembly is fixed to the chassis assembly.

[0004] Patent application number 201110107426.3 discloses a mobile lifting platform drilling rig for top and side anchor bolt and cable construction, including a tracked walking part, a body platform, a lifting platform, a platform lifting device, a drill arm part, a hydraulic drilling rig part, a temporary support device, a hydraulic operating system, a pump station part, and a main motor; it can construct top and side anchor bolts and cables, and also has functions such as constructing blast holes, gas discharge holes, and water exploration and drainage holes. It has better temporary support capabilities and ultra-high roadway support functions, adopts a fully hydraulic transmission system, and has good explosion-proof and safety performance.

[0005] Patent application number 202010181258.1 discloses an electro-hydraulic anchor protection control double-basket type two-arm anchor cable bolt drilling rig, including a traveling chassis, a vertical lifting platform, a rear frame, a left anchor protection boom, a right anchor protection boom, an advanced support device, and an automatic cable winding mechanism. The vertical lifting platform is arranged directly above the traveling chassis to achieve vertical lifting. A traveling reducer is installed on the rear side of the traveling chassis, and guide wheels are installed on the front side. The left and right anchor protection booms, which can be adjusted in height and swing on both sides, are symmetrically arranged on the vertical lifting platform. An advanced support device is also hinged to the front end of the vertical lifting platform. The rear frame is arranged behind the traveling chassis. A motor, a pump station, and an oil tank are installed sequentially on the upper left side of the rear frame to form a power system. The driver's cab and an electrical control box are arranged above the power system. An automatic cable winding mechanism and a cable winding guide roller group are installed on the left side of the driver's cab. A rear stabilizing shoe is installed at the bottom of the rear frame.

[0006] Although the existing two-arm bolting machine can drive bolts into the sidewalls of the roadway, it is difficult to drive bolts into the bottom of the sidewalls when driving bolts into the bottom of the sidewalls, even if the rear part of the main frame cylinder is fully raised and the front part of the main frame cylinder is fully retracted, and the support arm is lowered to the lowest point. In addition, the frequent operation of the main frame cylinder of the two-arm bolting machine at its maximum stroke can easily damage the main frame cylinder, making the two-arm bolting machine unusable and requiring frequent dredging and maintenance.

[0007] Therefore, a mobile side reinforcement support machine is proposed to address the above problems. Utility Model Content

[0010] Preferably, a winch is installed on the side of the gantry frame away from the lifting plate; a cable is wound inside the winch; the cable pulls the lifting beam up and down through a pulley mechanism.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 6 As shown, a mobile side reinforcement support machine includes a movable base frame 1; a portal frame 2 is fixedly connected to the center of the top surface of the base frame 1; a lifting beam 3 capable of being raised and lowered is slidably installed between the two side walls of the portal frame 2; a lifting plate 4 is fixedly connected to one side of the lifting beam 3; a guide rail 5 is fixedly connected to the top surface of the lifting plate 4; a rotary motor 6 is slidably installed on the top of the guide rail 5; the output shaft of the rotary motor 6 can be inserted into a support anchor rod.

[0033] In specific implementation, wheels 7 are installed on both sides of the middle of the base frame 1, and the wheels 7 on both sides are connected by a connecting shaft, which is fixed to the base frame 1 through a bearing seat; push rods are fixed to both sides of the gantry frame 2 away from the lifting plate 4; the wheels 7 and push rods facilitate the movement of personnel; vertical sliding grooves are opened on the side walls of the gantry frame 2 that are close to each other, and the two ends of the lifting beam 3 are sliders that match the vertical sliding grooves, and there are two parallel crossbars between the sliders on both sides; the lifting plate 4 is fixed to the crossbar at the bottom of the lifting beam 3, and the lifting plate 4... Both sides are fixed to the crossbar at the top of the lifting beam 3 by diagonal tie rods; by setting the lifting beam 3 in a U-shape, not only is the stability of the lifting beam 3 improved, but also the firmness of the lifting plate 4 is improved; the rotary motor 6 is powered by compressed air, and the rotation and reversing of the rotary motor 6 are controlled by the reversing valve of the rotary motor 6. The compressed air drives the gear of the rotary motor 6 to rotate, and after two-stage reduction, it drives the output column to rotate; and the end of the output shaft of the rotary motor 6 is set as a square column, and the tail of the support anchor rod is provided with a groove that matches the output shaft of the rotary motor 6;

[0034] During construction, the support machine is moved to the required construction position using wheels 7 and push rods. The lifting beam 3 is adjusted in height along the portal frame 2, which drives the lifting plate 4 to be adjusted to the construction height. At this time, the rotary motor 6 is located at the end of the guide rail 5 away from the construction position. The support anchor rod is placed on the top surface of the guide rail 5 and fixedly connected to the output shaft of the rotary motor 6. The air pump provides compressed air to the rotary motor 6, driving the output shaft of the rotary motor 6 to rotate, which in turn drives the support anchor rod to rotate, pushing the rotary motor 6 to slide along the guide rail 5 and pushing the support anchor rod to drill into the side walls of the roadway.

[0035] The lifting beam 3 can be adjusted in height along the gantry frame 2, allowing the lifting plate 4 and rotary motor 6 to descend to a lower position. This enables the support anchor bolts to reach the bottom of the sidewalls on both sides of the roadway, avoiding the difficulty of construction at lower positions that is present in existing two-arm anchor bolt machines. This reduces the difficulty of construction and improves construction efficiency.

[0036] A winch 8 is installed on the side of the gantry frame 2 away from the lifting plate 4; a cable 9 is wound inside the winch 8; the cable 9 pulls the lifting beam 3 up and down through a pulley mechanism;

[0037] In specific implementation, the pulley mechanism includes a fixed pulley 10 and a lifting ring 11 fixed to the bottom surface of the top crossbeam of the portal frame 2, and a movable pulley 12 fixed to the top surface of the lifting beam 3; the cable 9 passes through the fixed pulley 10 and the movable pulley 12 from the outlet of the winch 8, and is then connected and fixed to the lifting ring 11; the winch 8 is a hand-cranked winch and can be fixed and locked.

[0038] When in use, if the lifting beam 3 needs to be raised, the winch 8 is rotated to wind the cable 9 into the inside of the winch 8. Since the end of the cable 9 is fixed to the lifting ring 11 and passes over the fixed pulley 10, the cable 9 is retracted, which drives the movable pulley 12 and the lifting beam 3 to move upward. Furthermore, due to the arrangement of the fixed pulley 10, the lifting ring 11 and the movable pulley 12, half of the pulling force can be saved when pulling the lifting beam 3 to rise.

[0039] When the lifting beam 3 needs to be lowered, the winch 8 is rotated in the opposite direction to release the cable 9. Under the gravity of the lifting plate 4, guide rail 5 and rotary motor 6, the lifting beam 3 slides downward, pulling the cable 9 out of the winch 8. Due to the gravity of the lifting beam 3, lifting plate 4, guide rail 5 and rotary motor 6, the lifting beam 3 is lowered to the required height, thus effectively saving the operator's strength and facilitating the operator's operation.

[0040] Guide grooves 13 are provided on both sides of the guide rail 5; a rack 14 is fixedly connected inside one guide groove 13; side plates 15 are fixedly connected to both sides of the bottom surface of the rotary motor 6; a housing 16 is fixedly connected to the side of one side plate 15 away from the guide rail 5; a gear 17 that meshes with the rack 14 is provided on the side of the housing 16 near the guide rail 5; a feed motor 18 that can drive the gear 17 to rotate is fixedly connected to the top surface of the housing 16.

[0041] In practice, a base plate is fixed to the bottom surface of the rotary motor 6, and a first slot is opened on both sides of the base plate. A second slot matching the first slot of the base plate is opened on the top surface of the side plate 15. The base plate and the side plate 15 at the bottom of the rotary motor 6 are locked together by bolts. The side plates 15 on both sides are located on both sides of the guide rail 5. The side plates 15 on both sides limit the movement, thereby improving the stability of the rotary motor 6.

[0042] A through slot is provided in the middle of the side plate 15; the housing 16 is fixed to the outside of the through slot of the side plate 15; the side of the housing 16 near the side plate 15 is open, and the top and bottom are both fixed with protrusions passing through the through slot; a first rotating rod 19 is rotatably installed between the two protrusions of the housing 16 and inside the housing 16; a first gear 17 is sleeved and fixed on the outer ring of the first rotating rod 19 located at the opening of the housing 16; the output shaft of the feed motor 18 is fixed to the top of the first rotating rod 19 located inside the housing 16; a synchronous pulley 20 is fixed to the outer ring of both first rotating rods 19; a synchronous belt 21 is sleeved on the outer ring of the two synchronous pulleys 20; the feed motor 18 is also driven by compressed air to rotate the output column.

[0043] In use, the air pump provides compressed air to the feed motor 18, which drives the output shaft of the feed motor 18 to rotate, thereby rotating the first rotating rod 19 located inside the housing 16. After the synchronous pulley 20 and the synchronous belt 21 rotate, the first rotating rod 19 located at the opening of the housing 16 rotates, which in turn drives the first gear 17 to rotate. Since the first gear 17 meshes with the first rack 14, the side plate 15 and the rotary motor 6 slide along the guide rail 5, thereby pushing the support anchor rod into the side walls of the roadway.

[0044] Both sides of the side plate 15 near the guide rail 5 are fixed with a housing 22; the top and bottom of the housing 22 are provided with movable seats 23 that can move towards each other; multiple rollers 24 are rotatably mounted on the side of the movable seat 23 away from the housing 22.

[0045] In specific implementation, racks 25 are slidably installed on both sides of the inner side of the outer casing 22; the two racks 25 are fixedly connected to the two movable seats 23 respectively; a rotating rod 26 is rotatably installed in the middle of the outer casing 22; a gear 27 is fixedly connected to the outer ring of the middle part of the rotating rod 26; the gear 27 meshes with the racks 25 on both sides.

[0046] In use, rotating the second rotating rod 26 drives the second gear 27 to rotate. Since the second gear 27 meshes with the second rack 25, it pushes the second racks 25 on both sides away from each other, and pushes the two moving seats 23 away from each other, so that the top roller 24 contacts the top surface of the guide groove 13 and the bottom roller 24 contacts the top surface of the guide groove 13; thereby improving the stability and smoothness of the rotary motor 6 sliding along the guide rail 5.

[0047] The side plate 15 has adjustment slots 28 on both sides; the outer shell 22 has a protrusion 29 that matches the adjustment slots 28 fixed on the side near the side plate 15.

[0048] In practice, one end of the second rotating rod 26 rotates through the protrusion 29, and the end of the second rotating rod 26 is provided with an internal hexagonal groove; the protrusion 29 is slidably installed in the adjusting straight groove 28;

[0049] In use, the height of the outer shell 22 inside the guide groove 13 can be adjusted by sliding the protrusion 29 with the adjusting straight groove 28, which facilitates the adjustment so that the roller 24 contacts the top and bottom surfaces of the guide groove 13; at the same time, by using the protrusion 29 to pass through the adjusting straight groove 28, the end of the second rotating rod 26 passes through the side plate 15, which facilitates the operation and use of the staff.

[0050] A base 30 is fixedly connected to the top surface of one end of the guide rail 5 near the output shaft of the rotary motor 6; the base 30 is provided with a Y-shaped bracket 31 that can be raised and lowered.

[0051] In practice, a vertical groove is provided in the middle of the base 30, and the two sides of the vertical groove extend through the two sides of the base 30; the bottom of the Y-shaped bracket 31 is a column that matches the vertical groove, and the top is a U-shaped plate that matches the support anchor rod; the two sides of the column at the bottom of the Y-shaped bracket 31 are fixed and locked to the base 30 by bolts passing through the vertical groove.

[0052] When in use, adjust the height of the Y-shaped bracket 31 and lock it to the base 30 with bolts; use the Y-shaped bracket 31 to support and limit the support anchor rod, thereby preventing the support anchor rod from shifting and improving the accuracy of drilling the support anchor rod.

[0053] A toolbox 32 is fixedly connected to the top surface of the base frame 1 on the side away from the lifting plate 4;

[0054] In practice, the toolbox 32 has a cabinet door hinged to the side away from the lifting plate 4, and the top outer ring of the toolbox 32 is equipped with baffles on three sides; the toolbox 32 facilitates the storage of frequently used tools, thereby making it convenient for staff to use.

[0055] The base frame 1 is provided with lifting support feet 33 at each of its four corners; a drag bar 34 is hinged to the side of the base frame 1 near the lifting plate 4.

[0056] In practice, threaded holes are provided at all four corners of the base frame 1. The top of the support foot 33 is a screw that matches the threaded hole, and the bottom is a rubber block that is rotatably installed. The support foot 33 facilitates the fixing of the support machine. At the same time, the height of each support foot 33 can be adjusted to provide stable support and fixation in uneven areas. The towing bar 34 facilitates towing by vehicle.

[0057] Working principle: Using wheels 7 and push rods, the support machine is moved to the location where construction is required. When the lifting beam 3 needs to be raised, the winch 8 is rotated, and the cable 9 is wound into the inside of the winch 8. Since the end of the cable 9 is fixed to the lifting ring 11 and passes over the fixed pulley 10, the cable 9 is retracted, which drives the movable pulley 12 and the lifting beam 3 to move upward. Furthermore, due to the arrangement of the fixed pulley 10, the lifting ring 11 and the movable pulley 12, half of the pulling force can be saved when pulling the lifting beam 3 to rise.

[0058] When the lifting beam 3 needs to be lowered, the winch 8 is rotated in the opposite direction to release the cable 9. Under the gravity of the lifting plate 4, guide rail 5 and rotary motor 6, the lifting beam 3 slides downward, pulling the cable 9 out of the winch 8. Due to the gravity of the lifting beam 3, lifting plate 4, guide rail 5 and rotary motor 6, the lowering height of the lifting beam 3 is achieved. This allows the support anchor bolts to reach the bottom of the sidewalls on both sides of the roadway, avoiding the difficulty of construction at lower positions by existing two-arm anchor bolt machines, thereby reducing the construction difficulty and improving the construction efficiency.

[0059] The support anchor rod is mounted on the top surface of the Y-shaped bracket 31 and fixedly connected to the output shaft of the rotary motor 6. Compressed air is supplied to the rotary motor 6 using an air pump, driving the output shaft of the rotary motor 6 to rotate, which in turn drives the support anchor rod to rotate. At the same time, compressed air is supplied to the feed motor 18 using an air pump, driving the output shaft of the feed motor 18 to rotate, which in turn drives the first rotating rod 19 located inside the housing 16 to rotate. After the synchronous pulley 20 and the synchronous belt 21 rotate, the first rotating rod 19 located at the opening of the housing 16 rotates, which in turn drives the first gear 17 to rotate. Since the first gear 17 meshes with the first rack 14, the side plate 15 and the rotary motor 6 slide along the guide rail 5, pushing the support anchor rod to drill into the side walls of the roadway.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
