Description

Technical Field

[0001] This utility model relates to the technical field of under-mounted elevators, and in particular to a folding circulating under-mounted elevator. Background Technology

[0002] Structural columns and structural columns in building construction require manual pouring. The main task is to accurately deliver the well-mixed concrete into the structural column. At the same time, a supporting lifting mechanism is used to tilt and transfer the concrete raw materials (such as mortar buckets containing concrete) to match the height requirements of the structural column, reduce the intensity of manual handling, and improve the efficiency and quality of structural column pouring.

[0003] The supporting structure of structural columns generally adopts a double-body support design. Here, "double-body" usually refers to two parallel rigid columns or an integrated frame. In terms of the method of lifting the mortar bucket, most structural column pouring machines adopt an upward lifting design, that is, the mortar bucket is above the integrated frame and moves upward along the guide structure of the supporting body by chain traction. During the lifting process, there is obvious interference between the mortar bucket and the chain: specifically, the side wall of the mortar bucket rubs and collides with the chain links and the edge of the sprocket. This may not only cause wear on the edge of the mortar bucket and leakage of concrete slurry, but also increase the running resistance of the chain. Long-term use can easily lead to chain jamming, accelerated wear of transmission components, and generate greater operating noise.

[0004] Therefore, this utility model proposes a folding, circulating, under-mounted hoist to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a folding circulating under-mounted lifting machine, comprising: The foldable main structure includes a U-shaped frame plate, an upper connecting rod and a lower connecting rod disposed within the U-shaped frame plate and rotatably connected, a locking component for adjusting the rotation state of the upper connecting rod and the lower connecting rod is assembled between them, a lower support structure is assembled at the bottom of the lower connecting rod, and an upper support structure is assembled at the top of the upper connecting rod. The return transmission structure includes two rotary sprockets mounted on the opposite ends of the upper and lower connecting rods. The two rotary sprockets drive and mesh with a rotary chain. Multiple hooks are mounted at equal intervals along the surface of the rotary chain, and ash buckets are suspended on the hooks. The drive structure is mounted on the surface of the lower support structure and drives the rotary chain through a rotary sprocket at the lower end.

[0007] Preferably, the surface of the U-shaped frame plate is fitted with a guide sprocket, which is arranged at the open end opposite to the U-shaped frame plate and meshes with a rotary chain.

[0008] Preferably, the drive structure includes a motor mounting plate mounted on the lower support structure and a drive motor mounted on the motor mounting plate, wherein the output end of the drive motor is fixed to a rotating sprocket at the lower end.

[0009] Preferably, the lower support structure includes a transverse support plate, an extension support rod sleeved at both ends of the transverse support plate, and an auxiliary mounting plate assembled on the transverse support plate. The auxiliary mounting plate is fixedly connected to the fixed lower connecting rod. The surface of the extension support rod has multiple limiting holes, and bolt locking pairs are inserted into the limiting holes. The bolt locking pairs are simultaneously inserted into the kit part of the extension support rod and the transverse support plate. Two vertical mounting plates are symmetrically mounted on the surface of the horizontal support plate, and two sets of rollers are mounted on the vertical mounting plates.

[0010] Preferably, the upper support structure includes a transverse round rod that passes through the upper connecting rod and abutment components symmetrically fixed at both ends of the transverse round rod. The abutment components include a limiting ring, an abutment sleeve, a washer, and a locking nut that are sequentially sleeved on the transverse round rod. The limiting ring is fixed to the surface of the transverse round rod, and the transverse round rod and the locking nut are threadedly connected.

[0011] Preferably, the surface of the hook is provided with a hook groove to facilitate the hanging of the ash bucket.

[0012] The beneficial effects of this utility model are as follows: This application adopts a foldable main structure, which uses the upper and lower connecting rods to rotate around the U-shaped frame plate and lock in place with the mold locking pair. It can be unfolded to form a continuous rigid rod structure to ensure support stability, and can also be folded and stored when not in operation, greatly reducing the space occupied by the equipment during transportation and storage. At the same time, the lower support structure can flexibly adjust the extension length of the extension support rod by adjusting the position of the limiting hole of the bolt locking pair. The upper support structure can be rotated to abut the sleeve rod and lock the angle to adapt to different wall support surfaces, thus solving the problems of poor flexibility in fixing the support structure of the structural column casting machine, on-site placement and position adjustment.

[0013] This application adopts a bottom-hanging design for the ash bucket, where the ash bucket is suspended by hooks on the rotating chain, keeping the bucket away from the folding main structure. During operation, the ash bucket's gravity pulls the rotating chain to naturally straighten, and the guide sprockets on the U-shaped frame plate assist the chain's trajectory, effectively preventing interference between the ash bucket's sidewall and the rotating chain links or the edge of the rotating sprocket. This design not only eliminates ash bucket wear and mortar spillage but also reduces the rotating chain's running resistance, avoiding problems such as chain jamming and accelerated wear of transmission components caused by interference. It also reduces operating noise and improves the stability of material handling and the equipment's service life. Attached Figure Description

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1

[0021] Reference Figures 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a folding circulating under-hanging lifting machine, including: a folding main structure 010, which includes a U-shaped frame plate 011, an upper connecting rod 012 and a lower connecting rod 013 disposed within the U-shaped frame plate 011 and rotatably connected. The upper connecting rod 012 and the lower connecting rod 013 are symmetrically arranged about the U-shaped frame plate 011. A locking member 014 for adjusting the rotation state of the upper connecting rod 012 and the lower connecting rod 013 is assembled between them. The locking member 014 is configured as a mold locking pair, and the mold locking pair is a current The technology is available, but I won't go into too much detail here. When the upper connecting rod 012, the lower connecting rod 013, and the U-shaped frame plate 011 are not locked by the mold locking pair, the upper connecting rod 012 and the lower connecting rod 013 are in a folded state. When the upper connecting rod 012, the lower connecting rod 013, and the U-shaped frame plate 011 are locked by the mold locking pair, the three of them are in a straight line, forming a continuous rigid rod structure. The bottom of the lower connecting rod 013 is equipped with a lower support structure 040, and the top of the upper connecting rod 012 is equipped with an upper support structure 060. The return transmission structure 020 includes two rotating sprockets 021 mounted on the opposite ends of the upper connecting rod 012 and the lower connecting rod 013. The two rotating sprockets 021 drive and mesh with a rotating chain 022. Multiple hooks 030 are evenly spaced along the surface of the rotating chain 022, and mortar buckets are suspended from the hooks 030. The mortar buckets are filled with mortar. (Refer to...) Figure 4 As shown, the surface of the hook 030 is provided with a hook groove 031 to facilitate the hanging of the ash bucket; The drive structure 050 is mounted on the surface of the lower support structure 040 and drives the rotary chain 022 through a rotary sprocket 021 at the lower end.

[0022] Reference Figure 2 As shown, a guide sprocket 023 is mounted on the surface of the U-shaped frame plate 011. The guide sprocket 023 is arranged at the open end away from the U-shaped frame plate 011 and meshes with the rotary chain 022. When the folding main structure 010 is leaning against the wall surface during operation, the open end of its U-shaped frame plate 011 faces the wall. The mortar bucket is suspended by the hook 030 and located on the side of the folding main structure 010 closest to the wall. Under the gravity pull of the mortar bucket, the rotary chain 022 naturally shifts towards the wall, thus moving away from the guide sprocket 023 and the folding main structure 010. Under the gravity pull of the mortar bucket and the mortar, the rotary chain is stretched. The 022 strip ensures that the rotary chain 022 remains taut at all times, eliminating the need for the two rotary sprockets 021 to maintain strict tension on the chain. This reduces the tension requirements on the rotary chain 022 and minimizes wear on components caused by excessive tension. Simultaneously, the ash bucket is suspended from below, and the hook 030's structural design keeps the bucket away from the folding main structure 010, ensuring it does not contact or collide with the main structure during lifting. This maintains its vertical position, effectively preventing mortar spillage and improving the stability and safety of material handling.

[0023] Reference Figure 3 As shown, the drive structure 050 includes a motor mounting plate 051 mounted on the lower support structure 040 and a drive motor 052 mounted on the motor mounting plate 051. The output end of the drive motor 052 is fixed to a rotating sprocket 021 at the lower end.

[0024] Reference Figure 3 As shown, the lower support structure 040 includes a transverse support plate 045, an extension support rod 041 sleeved at both ends of the transverse support plate 045, and an auxiliary mounting plate 046 mounted on the transverse support plate 045. The auxiliary mounting plate 046 is fixedly connected to the fixed lower connecting rod 013.

[0025] Furthermore, the surface of the extension support rod 041 has multiple limiting holes 0411, and bolt locking pairs 042 are inserted into the limiting holes 0411. The bolt locking pairs 042 are simultaneously inserted into the assembly part of the extension support rod 041 and the transverse support plate 045.

[0026] Furthermore, two vertical mounting plates 043 are symmetrically mounted on the surface of the horizontal support plate 045, and two sets of rollers 044 are mounted on the vertical mounting plates 043.

[0027] Reference Figure 4As shown, the upper support structure 060 includes a transverse round rod 061 that passes through the upper connecting rod 012 and abutment components that are symmetrically fixed at both ends of the transverse round rod 061. The abutment components include a limiting ring 062, an abutment sleeve 063, a washer 064, and a locking nut 065 that are sequentially sleeved on the transverse round rod 061. The limiting ring 062 is fixed to the surface of the transverse round rod 061, and the transverse round rod 061 and the locking nut 065 are connected by threads.

[0028] Furthermore, the middle part of the transverse round rod 061 is a smooth round rod, and the surfaces of the rods at both ends are provided with tight threaded keyways. The abutment sleeve 063 can rotate freely around the smooth section of the transverse round rod 061 to adjust the angle. After the angle is determined, by tightening the locking nut 065 that mates with the threaded keyways at both ends of the transverse round rod 061, the locking nut 065 applies axial pressure to the abutment sleeve 063 through the washer 064. The other side of the abutment sleeve 063 is blocked by the limiting ring 062 fixed to the surface of the transverse round rod 061. Finally, under the clamping force of the limiting ring 062 and the washer 064, the angle of the abutment sleeve 063 is stably locked by the friction of the contact surface.

[0029] Working Principle: When using this folding circulating under-mounted hoist, firstly, the upper connecting rod 012 and lower connecting rod 013 of the folding main structure 010 are rotated and unfolded around the U-shaped frame plate 011. The three are then locked together by the mold locking pair to form a continuous rigid rod structure. Subsequently, a suitable position is selected to allow it to rest against the wall. The position of the limiting hole 0411 of the bolt locking pair 042 is adjusted according to the appropriate position to adjust the extension length of the extension support rod 041 relative to the transverse support plate 045. This adapts to the support height requirements of different operating scenarios, ensuring that the lower support structure 040 can provide sufficient support for the equipment. The system provides stable bottom support. After the lower support length is adjusted to the correct position and fixed by bolt locking pair 042, the angle of the abutting sleeve 063 in the upper support structure 060 is adjusted, and the locking nuts 065 at both ends of the horizontal round rod 061 are tightened. The abutting sleeve 063 is locked by the clamping force of the limiting ring 062 and the washer 064. At the same time, the support length is adjusted by the limiting hole 0411 of the extension support rod 041 of the lower support structure 040 and the bolt locking pair 042. The overall position is adjusted by the rollers 044 on the vertical mounting plate 043, so that the equipment is stably leaning against the wall. The drive motor 052 of the drive structure 050 is started, which drives the lower rotary sprocket 021 to rotate, thereby driving the rotary chain 022 meshing with the two rotary sprockets 021 to circulate. The guide sprocket 023 assists the rotary chain 022 in maintaining a stable trajectory. The hook 030 on the rotary chain 022 suspends the mortar bucket through the hook groove 031. Due to the gravity pull, the rotary chain 022 is naturally straightened and moved away from the folded main structure 010, ensuring that the mortar bucket remains vertical and does not collide during the lifting process. Finally, the mortar bucket is lifted and lowered circulatedly along the rotary chain 022 to complete the continuous transfer of mortar.

[0030] Example 2

[0031] Reference Figure 5 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in the embodiment 1, the foldable main structure 010 is locked in the unfolded state by the mold locking pair. In this embodiment, two sets of symmetrical triangular mounting plate groups are respectively assembled at the open end of the U-shaped frame plate 011. Each set of triangular mounting plate groups includes two triangular mounting plates 0111 installed on the left and right surfaces of the U-shaped frame plate 011. A set of locking bolts 0112 is inserted between the two sets of triangular mounting plates 0111, and a hexagonal nut is locked at one end of the locking bolt 0112 that protrudes from the triangular mounting plate 0111. The locking bolt 0112 is arranged perpendicular to the upper connecting rod 012 and the lower connecting rod 013 to lock the upper connecting rod 012 and the lower connecting rod 013 inside the U-shaped frame plate 011, so that the foldable main structure 010 is in the unfolded state under the locking of the locking bolt 0112.
