Description

Technical Field

[0001] The invention relates to the technical field of hoists, and in particular to a building material hoist with an anti-falling function. Background Art

[0002] A material hoist is a fixed mechanical conveying equipment, which is mainly suitable for the continuous vertical lifting of suitable materials. During the construction process, because there is a height difference between floors, a material hoist is needed to lift the construction materials to meet the needs of construction. The material hoist is mainly suitable for the continuous vertical lifting of powder, granular and small pieces of materials. During the construction process, high-rise buildings need to transport a large amount of materials to the upper floors. Generally, construction workers mostly rely on building material hoists to complete the material transportation.

[0003] For example, the Chinese patent with application number: 202321231093.X discloses a building material hoist, which belongs to the technical field of hoists and includes a base plate, an installation box is installed on one side of the upper end of the base plate, a height adjustment mechanism is installed on the side of the installation box, a telescopic rod is installed on the other side of the upper end of the base plate, a sliding seat is installed on the surface of the telescopic rod, a carrying box is installed on the side of the sliding seat, the carrying box is fixedly connected to the sliding seat through a carrying box fixing mechanism, a handle is installed on the upper end of the carrying box, a lifting rod is installed on the upper end of the installation box, a support plate is installed on the upper end of the lifting rod, a mounting plate is installed on the upper end of the support plate, and a motor is installed on the side of a group of mounting plates. By setting a height adjustment mechanism, the mechanism can facilitate the adjustment of the height of the hoist, thereby facilitating the lifting of building materials to a higher height. In addition, the mechanism can improve the stability of the lifting rod during the lifting process by setting a limit block and a limit groove.

[0004] The construction material hoist in the prior art generally lifts the carrying box by a rope, but the rope will wear out during the winding process and the rope may break. The construction material hoist in the prior art lacks the function of automatically locking the carrying box when the rope breaks. If the falling carrying box cannot be locked and is allowed to fall, it may not only cause the carrying box to be damaged by impact, but also may accidentally injure workers and cause safety accidents. In addition, the construction material hoist in the prior art lacks a dust removal mechanism. When workers load and unload materials in the carrying box, they are easily affected by dust, which not only has a certain impact on the physical and mental health of the workers, but also affects the efficiency of material loading and unloading.

[0005] Therefore, it is necessary to provide a building material hoist with an anti-falling function to solve the above-mentioned technical problems. Summary of the invention

[0063] Through the use of the locking mechanism B16 and the locking hole B18, when the wire rope 304 breaks and releases the lifting of the flip lifting handle 14 and the carrying box 6, the carrying box 6 can be locked, thereby preventing the carrying box 6 from falling out of control.

[0071] The blocking mechanism 21 includes a plurality of support rods 2101 fixedly mounted on the inner wall of the square tube 19 , a blocking plate 2102 is movably sleeved between the outer surfaces of the plurality of support rods 2101 , and a blocking spring 2103 is fixedly connected between the blocking plate 2102 and the square tube 19 .

[0072] The dust filtering mechanism 22 includes a suction fan 2201 and a dust box 2202 fixedly installed on the top of the base plate 1. A dust filter net 2203 is embedded in one side of the dust box 2202. A dust suction pipe 2204 is fixedly connected to the other side of the dust box 2202. The other end of the dust suction pipe 2204 is connected to the bottom square tube 19. The air inlet end of the suction fan 2201 is connected to the position of the dust filter net 2203 on the dust box 2202.

[0073] The dust suction mechanism 23 includes a U-shaped tube 2301 fixedly installed on the inner wall of the carrying box 6 near the top, and a plurality of dust suction ports 2302 are opened on the U-shaped tube 2301. A dust suction hose 2303 is fixedly connected to one side of the U-shaped tube 2301, and a connecting tube 2304 is fixedly connected to the other end of the dust suction hose 2303. One end of the connecting tube 2304 is fixedly connected to a hollow abutment frame 2305. The connecting tube 2304 is fixedly connected to the U-shaped locking frame 902. The connecting tube 2304 is adapted to be arranged to match the rectangular opening 20, and a sealing ring (not shown in the figure) is embedded on the inner wall of the rectangular opening 20. Through the setting of the sealing ring, when the connecting tube 2304 is inserted into the rectangular opening 20, the sealing performance of the connection between the connecting tube 2304 and the rectangular opening 20 can be improved, and the setting of the sealing ring can also improve the sealing performance of the connection between the sealing plate 2102 and the rectangular opening 20, thereby improving the sealing effect of the sealing plate 2102 on the rectangular opening 20.

[0074] A control panel is fixedly mounted on the side wall of the bottom support frame 2, and the electrical device in the present application is electrically connected to an external power source via the control panel.

[0075] Working principle: When in use, the flip lifting handle 14 is pulled upward by the winch lifting mechanism 3, and then the carrying box 6 is lifted by the flip lifting handle 14. When it is lifted to the required height, at this time, the locking mechanism A9 and the locking mechanism B16 are relative to the locking holes A17 and B18 on the corresponding support frame 2. Then, the hydraulic rod 901 is opened through the control panel to extend it, driving the U-shaped locking frame 902 to embed into the locking hole A17, locking the carrying box 6, and improving the stability of the carrying box 6. At the same time, the U-shaped locking frame 902 moves to drive the opening and closing mechanism 10 to operate, that is, the support bar 1001 and the U-shaped locking frame 902 move synchronously, driving the driving rack 1002 to move, and then driving the driving gear 1003 engaged therewith to rotate, and driving the box door 8 to rotate and open to a horizontal state through the rotating shaft A7, so that workers can load and unload materials into the carrying box 6;

[0076] When the U-shaped locking frame 902 moves toward the side close to the support frame 2, it simultaneously drives the connecting pipe 2304 and the hollow abutting frame 2305 to move, and pushes the corresponding blocking plate 2102 into the square tube 19 through the hollow abutting frame 2305 until the connecting pipe 2304 is connected with the square tube 19;

[0077] After the box door 8 is opened, the winch lifting mechanism 3 is turned on through the control panel to make it operate, and the lifting of the flip lifting handle 14 is released. At this time, the elastic force of the torsion spring 1402 drives the flip handle 1401 to rotate to one side of the support frame 2 until it fits with the top of the carrying box 6, so as to avoid the flip handle 1401 being located in the middle position of the top of the carrying box 6 and affecting the workers' loading and unloading operations of materials. At the same time, the elastic force of the locking spring 1603 pushes the locking bolt 1601 to be embedded in the locking hole B18 on the corresponding support frame 2, so as to complete the further locking of the carrying box 6, ensure the stability of the carrying box 6, and facilitate the workers to load and unload materials smoothly. At this time, the winch lifting mechanism 3 also provides an upward pulling force to the carrying box 6, thereby avoiding damage to the winch lifting mechanism 3 due to excessive load during loading and unloading of materials.

[0078] In the process of loading and unloading materials, the suction fan 2201 is turned on through the control panel, and the suction fan 2201 sucks the air inside the dust box 2202 outward, so that the inside of the dust box 2202 is in a negative pressure state, and the dust box 2202 and the U-shaped tube 2301 are connected through the dust suction hose 2303, the connecting tube 2304, the square tube 19, and the dust suction tube 2204, so that the dust suction port 2302 on the U-shaped tube 2301 has a certain suction force, so that when the workers load and unload materials into the carrying box 6, the carrying box 6 6, so as to avoid the dust impurities in the carrying box 6 being too large and affecting the physical and mental health of workers and the efficiency of material loading and unloading; the dust impurities sucked into the U-shaped tube 2301 through the dust suction port 2302 are successively transported to the dust collecting box 2202 through the dust suction hose 2303, the connecting pipe 2304, the square tube 19 and the dust suction hose, and the dust filter 2203 filters and intercepts the dust impurities, and the dust impurities are uniformly collected through the dust collecting box 2202, so as to facilitate the subsequent uniform cleaning of the collected dust impurities;

[0079] When the material loading and unloading is completed and the carrying box 6 needs to be lifted or lowered, the U-shaped locking frame 902 is first driven out of the locking hole A17 by contracting the hydraulic rod 901, and the box door 8 is driven to close by the closing mechanism. Then, by starting the winch lifting mechanism 3, the flip handle 1401 is first pulled up to a vertical state, and then the trigger block 13 is driven to move up, and the locking bolt 1601 is pulled out of the locking hole B18 by the trigger pull rope 1602 to release the lock of the carrying box 6. Then, the trigger block 13 is used to lift the carrying box 6, and then the lifting and lowering of the carrying box 6 is controlled by the reeling and unwinding of the winch lifting mechanism 3, so that the carrying box 6 can be lifted or lowered to the required height.

[0080] During the lifting and lowering operation of the carrying box 6, if the rope soil in the winch lifting mechanism 3 breaks, that is, the winch lifting mechanism 3 releases the lifting force on the flip lifting handle 14, at this time, the elastic force of the locking spring 1603 pushes the locking bolt 1601 to move to one side of the support frame 2 and abuts against the support frame 2, and then during the downward movement of the carrying box, when the locking bolt 1601 moves to a position relative to the locking hole, the locking bolt 1601 can be pushed into the locking hole under the elastic force of the locking spring 1603 to lock the carrying box 6, thereby preventing the carrying box 6 from falling out of control. It can not only prevent the carrying box from colliding with objects on the ground and being damaged, but also prevent the falling carrying box 6 from accidentally injuring workers, greatly improving the safety of the hoist during operation.

[0081] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that the guide mechanism 5 includes a fixed block 501 fixedly installed on one side of the carrying box 6, and a rotating shaft B502 is rotatably installed on the fixed block 501, and both ends of the rotating shaft B502 are rotatably connected to the limiting guide roller 503, and the limiting guide roller 503 is movably connected to the inside of the T-track 4.

[0082] Through the limiting action of the T-shaped track 4 on the limiting guide roller 503, the carrying box 6 can be indirectly limited so that it can only move vertically along the T-shaped track 4 but cannot move horizontally, thereby improving the stability of the carrying box 6 during the up and down movement.

[0083] Embodiment three: This embodiment is basically the same as the previous embodiment, except that the winch lifting mechanism 3 includes a mounting plate 301 fixedly mounted on the top of the topmost support frame 2, a winch motor 302 is fixedly mounted on the top of the mounting plate 301, a drum 303 is fixedly connected to the output end of the winch motor 302, a steel wire rope 304 is wound around the outer surface of the drum 303, and the other end of the steel wire rope 304 is fixedly connected to the flip handle 1401.

[0084] The hoisting motor 302 is turned on through the control panel, and the output end of the hoisting motor 302 rotates clockwise or counterclockwise, driving the drum 303 to reel in or unreel the wire rope 304. When the wire rope 304 is reeled in, the wire rope 304 provides an upward pulling force to the flip lifting handle 14, so that the flip lifting handle 14 is used to lift the carrying box 6 upward; when the wire rope 304 is unreeled and the carrying box 6 is not in a locked state, the carrying box 6 slowly descends; when the wire rope 304 is unreeled and the carrying box 6 is in a locked state, at this time, the wire rope 304 releases the pulling force on the flip lifting handle 14, so that the elastic force of the torsion spring 1402 can be used to drive the flip handle 1401 to fit the top of the carrying box 6 to avoid it being located in the middle position of the top of the carrying box 6, and it is convenient to use the elastic force of the locking spring 1603 to push the locking bolt 1601 to embed into the locking hole B18 to lock the carrying box 6.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
