Description

Technical Field

[0001] This utility model relates to the field of anchor beam installation technology, specifically a portable mine anchor beam mounting device. Background Technology

[0002] Mining anchor beams are key components of underground support and transportation systems, mainly divided into two categories: anchor beams and lifting beams. Anchor beams are used to reinforce the roof of roadways, forming an integral load-bearing body with the surrounding rock through anchor bolts and anchor cables to prevent roof collapse. Lifting beams are used in overhead monorail transportation systems to support the movement of equipment or materials. Anchor beam operations in mine retreat tunnels cannot be carried out simultaneously during the tunnel's initial construction, so secondary reinforcement support is usually adopted.

[0003] When performing secondary reinforcement support on the retreat passage, the anchor beams need to be transported to the top of the passage for installation. The anchor beams are transported to the construction site by transport vehicles, and workers carry out the installation work by moving the individual anchor beams and lifting them to the top of the passage using lifting equipment.

[0004] Because of the large weight and length of a single anchor beam, the existing lifting equipment needs to lift the anchor beam from the middle, while the two ends of the anchor beam have long suspended sections. This poses a risk of the anchor beam tilting and falling during the lifting and installation process, threatening the safety of construction workers.

[0005] Therefore, a portable mine anchor lifting beam device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A portable mining anchor lifting beam device of this utility model includes a scaffold; the scaffold includes columns, horizontal bars and diagonal braces; a lifting frame capable of being raised and lowered is slidably installed on the columns of the scaffold; a sliding rod is bolted to the top between two columns on both sides of the scaffold; a hand-operated hoist is hung at the bottom of both ends of the sliding rod; the hook of the hand-operated hoist is connected to the lifting frame.

[0008] Preferably, a blocking protrusion is fixed to the top of the side of the lifting frame away from the scaffold.

[0009] Preferably, the lifting frame has limit blocks fixedly attached to both sides of the side away from the scaffold; the limit blocks are in sliding contact with the side wall of the scaffold column.

[0010] Preferably, a guide wheel is bolted to the top of the scaffold column near the side of the hand chain hoist; the chain of the hand chain hoist passes around the guide wheel.

[0011] Preferably, the two ends of the slide rod are fitted with sliding frames; the inner top surface and bottom surface of the sliding frame are rotatably equipped with multiple pulleys that slide with the slide rod; and the bottom of the sliding frame is bolted with a lifting lug.

[0012] Preferably, the top two sides of the sliding frame are provided with fixing members that can press down the sliding rod.

[0013] Preferably, a connecting rod is bolted between the two sliding frames.

[0014] Preferably, the end of the chain of the hand chain hoist away from the lifting frame is fixed to both ends of the synchronizing rod.

[0015] Preferably, the outer rings at both ends of the synchronizing rod are provided with clamps that are fixed to the diagonal bracing of the scaffold.

[0016] The advantages of this utility model are:

[0017] 1. The portable mine anchor beam lifting device of this utility model, by setting up scaffolding, lifting frame and hand-operated hoists; by using the hand-operated hoists and lifting frame set on both sides, the two ends of the anchor beam are stably supported for lifting operations, thereby effectively reducing the probability of the anchor beam tilting and falling during lifting and installation, and improving the safety of workers; and by the labor-saving design of the hand-operated hoists and the large lowering height of the lifting frame, it is easy for the loader to automatically load and unload, thereby reducing the secondary handling work of workers, saving time and manpower, reducing labor intensity and improving construction efficiency.

[0018] 2. The portable mine anchor lifting beam mounting device of this utility model, by setting a blocking protrusion, the blocking protrusion, the supporting plate and the upright plate together form a concave structure.

[0030] 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.

[0031] like Figures 1 to 5 As shown, a portable mine anchor lifting beam device includes a scaffold 1; the scaffold 1 includes columns, horizontal bars, and diagonal braces; a lifting frame 2 capable of being raised and lowered is slidably installed on the columns of the scaffold 1; a sliding rod 3 is bolted to the top between two columns on both sides of the scaffold 1; a hand-operated hoist 4 is hung at the bottom of both ends of the sliding rod 3; the hook of the hand-operated hoist 4 is connected to the lifting frame 2;

[0032] In some embodiments, the scaffold 1 includes two pairs of uprights, with horizontal bars fixed to the top and bottom of each pair of uprights, and a pair of diagonally arranged tie rods fixed to each pair of uprights; a pair of diagonally arranged tie rods are fixed to both ends of the horizontal bars on both sides, and between the top horizontal bar on one side and the bottom horizontal bar on the other side; the scaffold 1, composed of uprights, horizontal bars and diagonally arranged tie rods, not only provides stable support for the upper beam operation of the anchor beam, but also facilitates the installation of the anchor beam by construction personnel;

[0033] Furthermore, by fixing the diagonal braces on both sides with crossbars, the influence of the diagonal braces on the operation of the hand-operated hoist 4 is avoided, thereby avoiding any impact on the upper beam operation of the anchor lifting beam.

[0034] The uprights of scaffold 1 are provided with a groove 5 in the middle; the lifting frame 2 is slidably installed inside the groove 5. The lifting frame 2 includes a slider that is slidably installed inside the groove 5. A vertical plate is fixedly connected to the side of the slider that is close to the outside of scaffold 1. A support plate is fixedly connected to the top of the vertical plate that is away from scaffold 1. A support diagonal bar is fixedly connected between the bottom surface of the support plate and the vertical plate. A limit plate is fixedly connected to the side of the slider that is close to the inside of scaffold 1. A hanging lug is fixedly connected to the side of the limit plate that is away from the slider.

[0035] Both ends of the slide bar 3 are equipped with hand chain hoists 4 via shackles; the hooks of the hand chain hoists 4 are connected to the lugs of the lifting frame 2;

[0036] In practical use, firstly, release the hand chain hoist 4 so that the lifting frame 2 slides down along the slide 5, so that the lifting frame 2 descends to the bottom of the scaffold 1, and ensure that the height of the lifting plates on both sides of the lifting frame 2 is consistent.

[0037] Then, a loader is used to place the single anchor beam onto the lifting plates on the two lifting frames 2 on both sides, ensuring that the distances from both ends of the anchor beam to the lifting frames 2 on both sides are similar;

[0038] Then, two workers pull the chains on the two hand chain hoists 4 respectively, so that the chains of the hand chain hoists 4 are pulled to the lifting frame 2 and slide upward along the slide 5. At the same time, the two workers need to keep the running speed of the two hand chain hoists 4 consistent, that is, ensure that the lifting rate of the two lifting frames 2 is consistent.

[0039] Finally, when the lifting frame 2 rises along the slide 5 to the installation height of the anchor beam, the chain of the hand chain hoist 4 is stopped, and at the same time, the workers on the scaffold 1 carry out the installation work of the anchor beam.

[0040] By using the hand-operated hoists 4 and lifting frames 2 installed on both sides, the two ends of the anchor beam are steadily lifted for lifting operations, thereby effectively reducing the probability of the anchor beam tilting and falling during lifting and installation, and improving the safety of the workers.

[0041] Furthermore, the labor-saving design of the hand chain hoist 4 and the significant drop height of the lifting frame 2 facilitate automatic loading and unloading by the loader, thereby reducing the secondary handling work of the workers, saving time and manpower, reducing labor intensity, and improving construction efficiency.

[0042] like Figures 4 to 5 As shown, a blocking protrusion 6 is fixedly connected to the top of the side of the lifting frame 2 away from the scaffold 1;

[0043] Furthermore, the blocking protrusion 6 is fixed to the top of the lifting plate of the lifting frame 2 on the side away from the scaffold 1; the blocking protrusion 6, the lifting plate and the upright plate together form a concave structure.

[0044] After the single anchor beam is placed on the support plate on the two lifting frames 2 on both sides, the anchor beam is placed in the concave structure formed by the blocking protrusion 6, the support plate and the upright plate. Because the anchor beam is blocked by the blocking protrusion 6, the anchor beam is prevented from rotating during the lifting and installation process and falling down, which further improves the safety of the workers.

[0045] like Figures 4 to 5 As shown, the lifting frame 2 has limit blocks 7 fixedly attached to both sides of the side away from the scaffold 1; the limit blocks 7 are in sliding contact with the side wall of the column of the scaffold 1.

[0046] Furthermore, the two limiting blocks 7 are respectively fixed to the top sides of the vertical plate of the lifting frame 2 and in contact with the side wall of the column of the scaffold 1.

[0047] By setting limit blocks 7 on both sides of the uprights of scaffold 1, the position of the lifting frame 2 is effectively restricted, preventing the lifting frame 2 from shaking, thereby further improving the stability of the anchor beam during the lifting process.

[0048] like Figures 1 to 4 As shown, a guide wheel 8 is bolted to the top of the column of the scaffold 1 near the side of the hand chain hoist 4; the chain of the hand chain hoist 4 passes around the guide wheel 8;

[0049] Furthermore, the guide wheel 8 includes a bracket, and a concave wheel is rotatably mounted in the middle of the bracket; the bracket is fixed to the upright of the scaffold 1 by bolts, and the concave wheel of the guide wheel 8 is located above the hanging lug of the lifting frame 2; the chain of the hand chain hoist 4 passes around the guide wheel 8, so that the chain of the hand chain hoist 4 is vertically connected to the hanging lug of the lifting frame 2.

[0050] When the chain of the hand chain hoist 4 is pulled, causing the lifting frame 2 to rise, the guide wheel 8 turns the chain of the hand chain hoist 4, so that the tension on the lifting frame 2 is vertically upward. This avoids the lifting frame 2 pressing against the inner wall of the slide groove 5 of the scaffold 1, which not only reduces the loss of force and is conducive to the operation of the workers, but also reduces the friction and compression loss between the lifting frame 2 and the slide groove 5, and reduces the deformation of the lifting frame 2 and the slide groove 5.

[0051] like Figures 6 to 8 As shown, sliding frames 9 are fitted around both ends of the sliding rod 3; multiple pulleys 10 that slide in cooperation with the sliding rod 3 are rotatably installed on the middle of the top surface and the bottom surface of the inner side of the sliding frame 9; and a lifting lug 11 is bolted to the bottom of the sliding frame 9.

[0052] In some embodiments, the sliding frame 9 includes two side plates, and connecting plates are fixedly connected to the top and bottom sides of one side plate. The width of the connecting plates is greater than the diameter of the slide rod 3. The two side plates are fixedly connected by multiple bolts passing through the connecting plates. The outer ring of the pulley 10 has a concave surface that matches the outer wall of the slide rod 3. A pulley 10 is rotatably installed on the top inner side of the sliding frame 9, and three pulleys 10 are installed on the bottom.

[0053] Through holes are provided between the connecting plates on both sides of the bottom of the sliding frame 9, and bolts are installed inside the through holes. The top of the lifting lug 11 is a cylinder, and the bottom is a U-shaped plate. The inner ring of the cylinder of the lifting lug 11 is threaded, so that the lifting lug 11 is installed on the outer ring of the bolt by rotating it through the thread. The lifting lug 11 is installed vertically downward between the two connecting plates at the bottom of the sliding frame 9. The threaded engagement between the lifting lug 11 and the bolt screw allows the lifting lug 11 to be locked and fixed after installation, thereby reducing the shaking of the hand chain hoist 4 during operation and improving the stability of the hand chain hoist 4 during operation.

[0054] By cooperating with the sliding frame 9, pulley 10 and lifting lug 11, the hand chain hoist 4 can be adjusted along the sliding rod 3, that is, the hand chain hoist 4 can move along the sliding rod 3 to both ends of the scaffold 1, thereby effectively reducing the investment of the hand chain hoist 4 by half and reducing the cost.

[0055] Furthermore, by coordinating the sliding frame 9, pulley 10, and lifting lug 11, the position of the hand chain hoist 4 can be adjusted, making it more convenient for the operator to operate.

[0056] like Figures 6 to 8 As shown, the top two sides of the sliding frame 9 are provided with fixing members 12 that can press down the sliding rod 3;

[0057] Furthermore, the fastener 12 is provided on the bottom surface of the connecting plates on both sides of the top of the sliding frame 9. The connecting plates on both sides of the top of the sliding frame 9 have threaded holes in the middle and guide holes on both sides. The bottom of the fastener 12 has a concave surface that matches the outer wall of the slide rod 3, and the concave surface has anti-slip texture.

[0058] A screw 13 that is threaded to a threaded hole is rotatably mounted on the center of the top surface of the fastener 12. The top of the screw 13 is provided with a hexagonal groove. Guide rods that match the guide holes are bolted to both sides of the top surface of the fastener 12.

[0059] In practical use, after the hand chain hoist 4 is adjusted to the position of the slide bar 3, the screw 13 is turned with a hex wrench to push the fixing part 12 down, causing the guide rod to slide along the guide hole. The fixing part 12 presses down on the top outer wall of the slide bar 3, fixing and locking the sliding frame 9, thereby restricting the position of the hand chain hoist 4 and preventing the hand chain hoist 4 from sliding during operation.

[0060] As shown in the figure Figure 3 and Figure 8 As shown, a connecting rod 14 is bolted between the two sliding frames 9 on both sides;

[0061] Furthermore, the sliding frames 9 on both sides are fixedly connected by the connecting rod 14, so that the sliding frames 9 on both sides can slide synchronously along the sliding rod 3, thereby realizing the synchronous movement of the positions of the hand chain hoists 4 on both sides, thus ensuring the consistency of the positions of the hand chain hoists 4 on both sides, and thus ensuring the consistency of the upward rate of the lifting frame 2 pulled by the hand chain hoists 4 on both sides.

[0062] like Figure 1 , Figure 3 and Figure 4 As shown, the end of the chain of the hand chain hoist 4 away from the lifting frame 2 is fixed to both ends of the synchronizing rod 15;

[0063] In some embodiments, the two ends of the synchronizing rod 15 are fixedly connected to the end of the chain of the hand chain hoist 4, and the chain of the hand chain hoist 4 can be wound onto the synchronizing rod 15; a pair of ring plates are fixedly connected to the outer rings of both ends of the synchronizing rod 15, and the chain of the hand chain hoist 4 is located between the two ring plates.

[0064] In actual use, the workers on both sides pull down the synchronizing rod 15 simultaneously. The synchronizing rod 15 descends in height, causing the chains of the hand chain hoists 4 on both sides to move synchronously, thereby ensuring the consistency of the running speed of the hand chain hoists 4 on both sides, and thus improving the stability of the lifting anchor beam of the lifting frame 2 on both sides.

[0065] like Figure 1 , Figure 3 , Figure 4 and Figure 9As shown, the outer rings at both ends of the synchronizing rod 15 are provided with clamps 16 that are fixed to the diagonal bracing of the scaffold 1;

[0066] Furthermore, the clamp 16 includes an H-shaped fixing frame, with baffles bolted to both the top and bottom of the fixing frame; the outer ring of the synchronizing rod 15 is set in the top groove of the fixing frame of the clamp 16;

[0067] The diagonal brace of scaffold 1 passes through the bottom groove of the fixing frame of clamp 16; a pair of trapezoidal clamping blocks 17 are provided in the bottom groove of the fixing frame, and the middle of the inclined surface of the clamping block 17 is provided with a groove that matches the diagonal brace of scaffold 1.

[0068] In practical use, the two clamping blocks 17 are used to clamp the diagonal brace of the scaffold 1 in the bottom groove of the fixing frame of the clamp 16, and are fixed by the baffle, so that the clamping blocks 17 press the diagonal brace of the scaffold 1, thereby fixing the clamp 16 to the diagonal brace of the scaffold 1; then the two ends of the synchronizing rod 15 are respectively installed into the top groove of the clamp 16 on both sides, and are blocked by the baffle.

[0069] The synchronizing rod 15 is rotated and installed onto the diagonal brace of the scaffold 1. When lifting the anchor beam, simply rotate the synchronizing rod 15 so that the chain on the hand chain hoist 4 is wound onto the synchronizing rod 15, thereby ensuring the synchronization of the operation of the workers on both sides, and thus ensuring the stability of the lifting frame 2 on both sides in lifting the anchor beam.

[0070] Working principle: Through the cooperation of sliding frame 9, pulley 10 and lifting lug 11, the hand chain hoist 4 can be adjusted along the sliding rod 3. After the hand chain hoist 4 is adjusted to the position of the sliding rod 3, the screw 13 is turned by using a hex wrench to push the fixing part 12 down, which drives the guide rod to slide along the guide hole. The fixing part 12 presses down on the top outer wall of the sliding rod 3 to fix and lock the sliding frame 9.

[0071] The clamp 16 is fixed to the bottom groove of the fixture frame. Two clamping blocks 17 are used to clamp the diagonal brace of the scaffold 1 and fixed with a baffle. The clamping blocks 17 press the diagonal brace of the scaffold 1, thereby fixing the clamp 16 to the diagonal brace of the scaffold 1. Then, the two ends of the synchronizing rod 15 are respectively installed into the top groove of the clamp 16 on both sides and blocked by a baffle.

[0072] First, release the chain hoist 4 so that the lifting frame 2 slides down along the slide 5, so that the lifting frame 2 descends to the bottom of the scaffold 1, and ensure that the height of the lifting plates on both sides of the lifting frame 2 is consistent.

[0073] Then, a loader is used to place the single anchor beam onto the lifting plates on the two lifting frames 2 on both sides, ensuring that the distances from both ends of the anchor beam to the lifting frames 2 on both sides are similar;

[0074] Then, two workers rotate the two ends of the synchronizing rod 15 respectively, so that the chain on the hand chain hoist 4 is wound onto the synchronizing rod 15, so that the chain of the hand chain hoist 4 is pulled to the lifting frame 2 and slides upward along the slide groove 5. At the same time, the two workers need to keep the running speed of the hand chain hoist 4 on both sides consistent, that is, ensure that the lifting rate of the lifting frame 2 on both sides is consistent.

[0075] Finally, when the lifting frame 2 rises along the slide 5 to the installation height of the anchor beam, the synchronous rod 15 is stopped from rotating, so that the hand chain hoist 4 stops pulling the lifting frame 2. At the same time, the workers on the scaffold 1 carry out the installation work of the anchor beam.

[0076] The hand-operated hoists 4 and lifting frames 2 installed on both sides smoothly support both ends of the anchor beam for lifting operations, thereby effectively reducing the probability of the anchor beam tilting and falling during lifting and installation, and improving the safety of workers. In addition, the labor-saving design of the hand-operated hoists 4 and the significant drop height of the lifting frames 2 facilitate automatic loading and unloading by the loader, thereby reducing the secondary handling work of workers, saving time and manpower, reducing labor intensity, and improving construction efficiency.

[0077] 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. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
