Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a block lifting and loop feeding device and its construction method. Background Technology

[0002] During bricklaying construction, lifting mechanisms are needed to supply aerated concrete blocks and other bricks to higher construction positions. A jack-type crane is a commonly used lifting mechanism, which can be freely assembled according to the construction site environment. Its disadvantage is that the material supply is discontinuous, resulting in low efficiency. Chinese patent application CN115709962A discloses a brick lifting device for building construction, which has a movable base, an adjustable frame, a storage box for holding bricks, and a motor and a winding roller for lifting the storage box. The lifting and lowering of the storage box is driven by the winding roller, completing the brick lifting and supply. However, because the lifting and lowering are alternating, the material supply is not continuous, affecting efficiency. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a block lifting and circular feeding device and its construction method, which uses a ring chain lifting mechanism to drive the carrier frame to make a circular motion for continuous lifting and feeding, thereby improving efficiency and stability.

[0004] To achieve these objectives of the present invention, the present invention provides a block lifting and loop feeding device, comprising:

[0005] Track mechanism;

[0006] The slide block is in sliding engagement with the track mechanism;

[0007] A shelf, which is connected to the slide;

[0008] A chain lifting mechanism, which is connected to the carrying rack;

[0009] Driven by the chain lifting mechanism and constrained by the slide, the carrier moves in a circular motion along the track mechanism.

[0010] In this embodiment, the slide block slides along the track mechanism and is connected to the carrying frame, which improves the stability of the carrying frame being driven by the chain lifting mechanism to make circular motion. The carrying frame makes circular motion to lift the blocks for feeding, which improves the continuity of feeding and improves efficiency.

[0011] Preferably, the slide includes:

[0012] Seat plate, which has mounting holes for connection with chain lifting mechanism;

[0013] The first rollers, which are horizontally opposed to each other, are rotatably disposed on the first side of the seat plate;

[0014] The second roller, which is vertically opposed to the upper and lower parts, is rotatably mounted on the first side of the seat plate;

[0015] The first and second rollers slide in contact with the track section of the track mechanism, so that the slide remains stable when it slides along the track mechanism.

[0016] More preferably, the track part of the track mechanism includes a track groove and a track surface, the second roller is shorter than the first roller, the first roller is inserted into the track groove for sliding engagement, and the end face of the second roller engages with the track surface to form multiple sliding contact limit points, thereby improving the stability of the slide and the carrier during movement.

[0017] Preferably, the track mechanism includes:

[0018] A panel with a track groove in its middle, which forms several groove plates, and the surface of the groove plates constitutes the track surface.

[0019] The back panel is located on the back of the panel and is fixedly connected to the panel and the groove plate.

[0020] In this embodiment, the track mechanism constructed from the panel and back plate has a simple structure, is easy to process, and has high overall structural strength, making it easy to install.

[0021] More preferably, the track grooves are formed on both sides of the groove plate, and the two first rollers are horizontally opposed and fitted in the track grooves on both sides of the groove plate to form a sliding clamping structure for the groove plate, preventing the slide from rotating, keeping the slide horizontal when moving, improving the stability of the rack, and preventing tipping.

[0022] More preferably, the panel is provided with arc plates on the top and bottom, and the inner side of the arc plates forms an arc surface. When the slide moves to the top or bottom of the ring with the chain lifting mechanism, the side of the second roller of the slide contacts the arc surface, which makes the slide stable.

[0023] Preferably, the transmission chain of the chain lifting mechanism is provided with a sleeve on its outer periphery, the sleeve rod rotates into and passes through the sleeve, the first end of the sleeve rod is connected and fixed to the base plate through the mounting hole, and the second end of the sleeve rod is connected and fixed to the load rack.

[0024] Preferably, the system further includes a base, on which the track mechanism is mounted and fixed. More preferably, the base is a movable base and is equipped with wheels.

[0025] Preferably, it also includes a mounting frame, and the track mechanism is located inside the mounting frame and connected and fixed to the mounting frame.

[0026] Preferably, it also includes an adjustment bracket, which is telescopically mounted on the base.

[0027] More preferably, the adjusting frame includes a jack, a vertical rod, and an adjusting rod; the jack is mounted on the base, the vertical rod is vertically connected to the jack, and the adjusting rod is inserted into the top of the vertical rod and threadedly engaged, entering and exiting the vertical rod during screwing to adjust the height; the vertical rod is sleeved with the mounting frame via a collar.

[0028] The construction method of the block lifting and cyclic feeding device of the present invention includes:

[0029] Push the block lifting and loop feeding device to the construction position, then raise the adjusting rod so that the adjusting rod supports the ceiling of the building. The upright rod is further lifted by the jack so that the adjusting rod is further pressed against the ceiling. At this time, the base of the block lifting and loop feeding device supports the ground and the adjusting frame is pressed against the ceiling, forming a top-bottom support structure, which improves the structural stability of the block lifting and loop feeding device and prevents tilting and overturning during construction.

[0030] Place the blocks to be lifted into the frame, start the chain lifting mechanism to drive the frame to lift and supply the blocks to the higher construction position. The blocks are then removed from the frame at the higher construction position, and the frame continues to make a circular motion, returning to the initial position, and the process is repeated.

[0031] Preferably, several shelves can be provided, preferably in pairs, such as 2, 4 or 6, and more preferably symmetrically.

[0032] The present invention has at least the following beneficial effects:

[0033] In the block lifting device of the present invention, the slide slides along the track mechanism and is connected to the carrier frame, which improves the stability of the carrier frame being driven by the chain lifting mechanism to make a circular motion. The carrier frame makes a circular motion to lift the blocks for feeding, which improves continuity and efficiency.

[0034] The slide of the present invention includes a first roller and a second roller, and the track mechanism includes a track groove and a track surface. The first roller is slidably engaged with the track groove, and the second roller is slidably engaged with the track surface, which effectively reduces the rotation of the slide and the load frame and improves the stability of the load movement.

[0035] The adjustment frame of this invention has a telescopic adjustment function. The adjustment rod at the top can be adjusted to a large degree of height. It is used to support the top of the ceiling of the building. The jack located at the bottom of the upright plays a role in fine adjustment of the height, so that the adjustment frame is tightly against the ceiling, forming a top-to-bottom support structure, which effectively improves the structural stability of the device and makes the construction smooth and safe.

[0036] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0043] The present invention will be further described in detail below with reference to examples, so that those skilled in the art can implement it based on the description.

[0044] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0045] like Figures 1-6 As shown, a block lifting and cyclic feeding device of the present invention includes:

[0046] Track mechanism 40;

[0047] The slide block 30 is slidably engaged with the track mechanism 40, and the slide block 30 slides along the track mechanism 40.

[0048] A shelf 60 is connected to the slide 30;

[0049] A chain lifting mechanism 50 is connected to the rack 60;

[0050] Driven by the chain lifting mechanism 50 and constrained by the slide 30, the carrier 60 moves in a circular motion along the track mechanism 40, thereby lifting the block supply to a high construction position.

[0051] In the illustration, the track mechanism 40 has a circular track, which is vertically arranged with vertical sections on both sides and arc-shaped sections at the top and bottom. The slide 30 slides in conjunction with the track mechanism 40, so it can also make circular motion. The shelf 60 is connected to the slide 30. The chain lifting mechanism is a circular drive mechanism that drives the shelf 60 and the slide 30 to make circular motion along the track mechanism 40. Under the constraint of the slide 30 and the track mechanism 40, the shelf 60 runs more stably.

[0052] During construction, the device of this invention is installed at the building construction site. The blocks to be lifted are moved or pushed into the support frame 60 from the lower construction site. The chain lifting mechanism 50 is activated, and the support frame 60 is vertically lifted to the higher construction site. The blocks are then removed or pushed out of the support frame 60. The support frame continues its circular motion until it returns to its initial position, and the next block lifting operation continues. Several support frames can be set as needed, such as 2, 4, or 6.

[0053] The advantage of this embodiment is that the slide block slides along the track mechanism and is connected to the carrying frame, which improves the stability of the carrying frame being driven by the chain lifting mechanism to make a circular motion. The carrying frame makes a circular motion to lift the blocks for feeding, which improves continuity and efficiency.

[0054] Furthermore, in another implementation, such as Figure 5 As shown, the slide 30 includes:

[0055] The base plate 303 has a mounting hole 304 for connection with the chain lifting mechanism 50; in the illustration, the base plate 303 is a quadrilateral structure, and the mounting hole 304 is disposed through the middle of the base plate 303, such as... Figure 2 and 4 As shown, the seat plate 303 is fixedly connected to the first end of the sleeve rod 305 through the mounting hole 304, and the second end of the sleeve rod 305 is fixedly connected to the shelf 60.

[0056] The first rollers 301, which are horizontally opposed to each other, are rotatably disposed on the first side of the seat plate 303; in the illustration, a pair of first rollers 301 are rotatably disposed at the left and right corners of the first side of the seat plate 303 via a central axis, and are horizontally symmetrical.

[0057] The second roller 302, which is vertically opposed, is rotatably disposed on the first side of the seat plate 303; in the illustration, the second roller 302 is rotatably disposed at the upper and lower corners of the first side of the seat plate 303 via a central axis, and is symmetrical in the upper and lower parts.

[0058] like Figure 2 and 6 As shown, the first roller 301 and the second roller 302 are slidably engaged with the track portion of the track mechanism 40, so that the slide block 30 remains stable when it slides along the track mechanism 40.

[0059] Furthermore, such as Figure 3 As shown, the track section of the track mechanism 40 includes a track groove 404 and a track surface 403, as... Figure 6 As shown, the second roller 302 is shorter than the first roller 301. The two first rollers 301 are respectively inserted into the track groove 404 for sliding engagement. The end face of at least one second roller 302 is in close engagement with the track surface 403, thereby forming multiple sliding contact points, which can effectively limit the movement of the slide and thus improve the stability of the slide and the load-bearing movement of the load-bearing frame.

[0060] Specifically, in one implementation, such as Figure 3 and 6 As shown, the track mechanism 40 includes:

[0061] The panel 401 has a track groove 404 in its middle. In the example, the track groove has three channels: left, middle and right. After the track groove 404 is opened, a plurality of slot plates 408 are formed. The surface of the slot plates 408 constitutes the track surface 403. In the example, the slot plates 408 are fixed to the back plate 402 by connecting plates 407, such as by welding or bolting.

[0062] The back plate 402 is located on the back of the panel 401 and is fixedly connected to the panel 401 and the groove plate 408. In the illustration, the back plate has a U-shaped cross-section and is fixed to the back of the panel 401 to increase the depth of the track groove, thereby allowing the first roller 301 to fit deeply and prevent dislocation.

[0063] In this embodiment, the track mechanism constructed from the panel and back plate has a simple structure, is easy to process, and has high overall structural strength, making it easy to install.

[0064] Furthermore, such as Figure 6 As shown, the track grooves 404 are formed on both sides of the groove plate 408. The first roller 301 of the slide block 30 is horizontally opposed and fits in the track grooves 404 on both sides of the groove plate 408, forming a sliding clamping structure for the groove plate 408. This can prevent the slide block 30 from twisting, so that the slide block 30 remains horizontal when it moves. During the process of loading blocks and lifting materials, the loader remains horizontal and stable, preventing tipping and ensuring high safety.

[0065] Furthermore, in another implementation, such as Figure 2 and 3 As shown, the panel 401 is provided with arc plates 406 on the top and bottom, and the inner side of the arc plate 406 forms an arc surface 405. When the slide 30 moves to the top or bottom of the ring with the chain lifting mechanism 50, the side of the second roller 302 of the slide 30 contacts the arc surface 405, so that the slide 30 is stable and does not twist, thereby making the rack 60 stable and does not tip over.

[0066] Furthermore, in another implementation, such as Figure 2 , 4 As shown in Figure 6, a sleeve 503 is provided on the outer periphery of the transmission chain 501 of the chain lifting mechanism 50. The sleeve 503 is rotatably sleeved on the sleeve rod 305. The first end of the sleeve rod 305 is connected and fixed to the seat plate 303 through the mounting hole, and the second end of the sleeve rod 305 is connected and fixed to the carrier 60.

[0067] like Figure 6 As shown in the illustration, the chain lifting mechanism 50 includes a drive motor 504. The drive motor 504 drives the chain gear 502 to rotate via a rotating shaft 505. The chain gear 502 meshes with the transmission chain 501, causing it to perform a circular motion. The sleeve 503 is fixed to the outer circumference of the transmission chain 501, thus enabling it to perform a circular motion with the transmission chain 501. The sleeve rod 305 is rotatably fitted onto the sleeve 503. Under the constraint of the slide 30 and the track mechanism 40, the sleeve rod 305 does not rotate during the circular motion with the transmission chain 501, and the shelf 60 does not twist, but instead performs a circular motion in a horizontal state. In the illustration, the rotating shaft 302 passes through the back plate 402, and the drive motor is located on the back side of the back plate. The sleeve 503 is limited at both ends by nuts, preventing the sleeve rod 305 from detaching from the sleeve 503. Figure 1 As shown, there are several chain gears 502, one of which is set as the driving gear and driven by the drive motor 504, while the others are driven gears.

[0068] Furthermore, in another implementation, such as Figure 1 As shown, it also includes a base 10, on which the track mechanism 40 is mounted and fixed. More preferably, the base 10 is a movable base and is provided with wheels 101.

[0069] Furthermore, such as Figure 1 As shown, it also includes a mounting frame 70, and the track mechanism 40 is located inside the mounting frame 70 and fixedly connected to the mounting frame 70, so the track mechanism 40 and the mounting frame 70 form an integral unit. The mounting frame 70 provides a mounting base for the track mechanism 40 and the drive motor 504.

[0070] Furthermore, such as Figure 1As shown, it also includes an adjustment frame 20, which is telescopically mounted on the base 10. Specifically, the adjustment frame 20 includes a jack 201, a vertical rod 202, and an adjustment rod 204. The jack 201 is mounted on the base 10, the vertical rod 202 is vertically connected to the jack 201, and the adjustment rod 204 is inserted into the top of the vertical rod 202 and threadedly engaged. It enters and exits the vertical rod 202 during tightening, thereby adjusting the height. A collar 203 is fixed to the outside of the mounting frame 70, and the vertical rod 202 is engaged with the mounting frame 70 through the collar 203. In the illustration, the vertical rod 202 has internal threads, and the adjustment rod 204 is a threaded rod that engages with the internal threads of the vertical rod, thus allowing for height adjustment by tightening. The jack, located at the bottom, allows for fine-tuning of the height, ensuring that the adjustment rod 204 is firmly against the ceiling of the building. A pad 205 is provided at the top of the adjustment rod 204 to increase the contact area. Furthermore, a level can be installed on the base or the vertical rod.

[0071] A construction method for the block lifting and loop feeding device of the present invention includes:

[0072] like Figure 1 As shown, the block lifting and loop feeding device is pushed to the construction position, and then the adjusting rod 204 is raised so that the adjusting rod 204 supports the ceiling of the building. The upright is further lifted by the jack 201 so that the adjusting rod is further pressed against the ceiling. At this time, the base of the block lifting and loop feeding device supports the ground, and the adjusting frame is pressed against the ceiling, forming a top and bottom support structure, which improves the structural stability of the block lifting and loop feeding device and prevents tilting and overturning during construction.

[0073] At the lower construction position, the blocks to be lifted are placed into the support frame. The chain lifting mechanism is then activated to drive the support frame to lift and supply materials to the higher construction position. At the higher construction position, the blocks are removed from the support frame, and the support frame continues its circular motion back to its initial position. Conversely, building materials at the higher construction position can be lowered to the lower construction position via the support frame. Several support frames can be installed, preferably in pairs, such as 2, 4, or 6, and more preferably symmetrically.

[0074] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Further modifications can be readily implemented by those skilled in the art.
