Description

Technical Field

[0001] This utility model relates to the field of housing construction technology, and in particular to a hoisting device for building materials in housing construction. Background Technology

[0002] During building construction, materials need to be vertically transported to a designated height using hoisting equipment, and then horizontally transported to the designated construction location. For example, Chinese utility model patent CN220642229U discloses a building construction material hoisting device, which includes a base plate, a support rod fixedly connected to the top of the base plate, a material frame set on one side of the support rod, symmetrically distributed rotating plates hinged to the bottom of the material frame, a locking post fixedly connected to one side of each rotating plate, a rotating block rotatably connected to the side of the material frame near the locking post, and two locking slots opened inside the rotating block, with the locking post slidingly locking into the corresponding locking slot.

[0003] While this hoisting equipment can meet the needs of material hoisting, it has shortcomings in use: when the worm gear and worm control the rotating rod to rotate, the mounting plate rotates along with the rod. However, because workers need to manually operate the handle during rotation, the mounting plate is prone to colliding with workers, posing a safety hazard. Therefore, there is a need to provide a building construction material hoisting device that can solve the problem of potential collisions with workers during the use of this hoisting equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide a hoisting device for building construction materials, which can solve the problem that the hoisting equipment may collide with workers during use.

[0005] This utility model is implemented as follows:

[0006] A building construction material hoisting device includes a base, a column, a connecting plate, a hoisting component, a drive component, a mounting plate, a rotating component, a limiting sleeve, and a positioning rod. The column is vertically fixed on the base, and the hoisting component is rotatably mounted on the column via the rotating component. Building construction materials are suspended on the hoisting component. The connecting plate is fixedly mounted on the rotating component. One end of the mounting plate is vertically rotatably connected to the connecting plate and is located above the rotating component. The drive component is located at the other end of the mounting plate and is connected to the hoisting component. Limiting sleeves are provided on the side walls of both the connecting plate and the mounting plate. When the mounting plate rotates to a horizontal position, the positioning rod can be horizontally inserted into the limiting sleeves on the connecting plate and the mounting plate. When the mounting plate rotates upward to a vertical position, the positioning rod can be vertically inserted into the limiting sleeves on the connecting plate.

[0007] The drive assembly includes a motor and a winding reel. The motor is fixedly mounted on the end of the mounting plate away from the connecting plate, and the winding reel is coaxially fixed to the output shaft of the motor. The hoisting assembly is connected to the winding reel.

[0008] The mounting plate has a bearing seat at the end away from the connecting plate. The bearing seat is connected to the end of the winding wheel away from the motor, so that the winding wheel can be rotatably mounted on the mounting plate.

[0009] The hoisting assembly includes a support arm, a fixed wheel, a wire rope, and a hook; one end of the support arm is fixedly mounted on a rotating assembly, and the other end of the support arm extends obliquely upward; the fixed wheel is rotatably mounted on the other end of the support arm; one end of the wire rope is wound on a take-up reel, and the other end of the wire rope is wound around the fixed wheel and connected to a hook, on which building construction materials are suspended.

[0010] The hoisting assembly also includes positioning plates and rotating rollers; a pair of positioning plates are symmetrically fixed on both sides of one end of the support arm, and the rotating rollers are rotatably installed between the pair of positioning plates; and the height of the roller shaft is lower than the height of the fixed wheel and the height of the winding wheel, so that the wire rope hangs down naturally after passing through the bottom of the roller shaft and the top of the fixed wheel.

[0011] The rotating assembly includes a mounting base, a support rod, a crank handle, a worm gear, and a worm wheel. The mounting base is fixedly installed on the top of the column. The worm gear and the worm wheel are rotatably installed in the mounting base, and the worm wheel and the worm gear are meshed and connected for transmission. The lower end of the support rod is coaxially fixed to the worm wheel, one end of the support arm is fixedly installed on the upper end of the support rod, and a connecting plate is installed on the top side of the support rod. One end of the crank handle is inserted into the mounting base and coaxially fixed to one end of the worm gear, and the other end of the crank handle is located on the top side of the column.

[0012] A support ring is fixedly connected to the middle of the support rod, and a top rod is connected between the support ring and the middle of the support arm.

[0013] The base is equipped with a counterweight, which is located on the side of the bottom of the column.

[0014] The base and the column are connected at an angle by a tie rod, and the two tie rods are symmetrically arranged on the front and rear sides of the counterweight.

[0015] The positioning rod has an L-shaped structure, and a stop is provided on the mounting plate. The distance between the limiting sleeve on the mounting plate and the stop is less than the length of the horizontal section of the positioning rod, so that when the horizontal section of the positioning rod is movably inserted into the limiting sleeve, the vertical section of the positioning rod can contact and connect with the stop.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. Because this utility model is equipped with a limiting sleeve and a positioning rod, when the positioning rod is inserted into the lateral hole of the upper limiting sleeve of the connecting plate, the mounting plate can be horizontally connected to the connecting plate, which facilitates the drive assembly to drive the hoisting assembly to vertically hoist building materials; when the positioning rod is inserted into the top hole of the upper limiting sleeve of the connecting plate, the mounting plate can be vertically connected to the connecting plate, which facilitates the drive assembly and the mounting plate to avoid the area where the workers are located when rotating with the rotating assembly, thereby avoiding collisions with the workers and effectively reducing construction safety hazards.

[0018] 2. This utility model is equipped with a hoisting component, a drive component, and a rotating component. The motor controls the winding wheel to wind or release the wire rope, thereby vertically hoisting building materials via the hook. At the same time, the operator turns the crank, which drives the support rod to rotate under the meshing transmission of the worm gear and worm wheel, and drives the hoisting component and drive component to rotate synchronously, thereby realizing the lateral transportation of building materials. The hoisting operation is simple, easy to control, and highly safe. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please see the appendix Figure 1 To be continued Figure 4A building construction material hoisting device includes a base 1, a column 2, a connecting plate 4, a hoisting component, a drive component, a mounting plate 7, a rotating component, a limiting sleeve 21, and a positioning rod 22. The column 2 is vertically fixed on the base 1, and the hoisting component is rotatably mounted on the column 2 via the rotating component. Building construction materials are suspended on the hoisting component. The connecting plate 4 is fixedly mounted on the rotating component. One end of the mounting plate 7 is vertically rotatably connected to the connecting plate 4 via a pin and is located above the rotating component. The drive component is located at the other end of the mounting plate 7 and is connected to the hoisting component. Limiting sleeves 21 are provided on the side walls of both the connecting plate 4 and the mounting plate 7. When the mounting plate 7 is rotated to a horizontal state, the positioning rod 22 can be horizontally inserted into the limiting sleeves 21 on the connecting plate 4 and the mounting plate 7. When the mounting plate 7 is rotated upward to a vertical state, the positioning rod 22 can be vertically inserted into the limiting sleeves 21 on the connecting plate 4.

[0026] Preferably, the base 1 can adopt a rectangular planar structure, which can be stably placed on the ground, with a large contact area to ensure the stability of the entire device during operation. The column 2 can adopt a cylindrical structure for mounting the rotating component. The height of the column 2 can be adapted to the actual use requirements to ensure that the operator can easily operate the rotating component.

[0027] The hoisting assembly is used to lift and transport building materials under the drive of the drive assembly. The height of the hoisting assembly can be adjusted to meet the hoisting requirements. The rotating assembly is used to rotate the hoisting assembly and the drive assembly, thereby facilitating the lateral transport of building materials.

[0028] The drive assembly on the mounting plate 7 is located next to the worker. To prevent the mounting plate 7 and the drive assembly from colliding with the worker when they rotate, the mounting plate 7 can be rotated upwards to a vertical position, thereby minimizing the risk of collision between the mounting plate 7 and the drive assembly and the worker.

[0029] Preferably, a limiting sleeve 21 and a positioning rod 22 can be provided on the front and rear sides of the connecting plate 4 and the mounting plate 7 to facilitate the safe locking and limiting of the mounting plate 7.

[0030] When the hoisting and driving components vertically hoist building materials, the mounting plate 7 is in a horizontal state. When the rotating components horizontally transport building materials, the mounting plate 7 is in a vertical state. Preferably, a limiting sleeve 21 with a through hole can be provided on the mounting plate 7, and a positioning rod 22 passes through the through hole of the limiting sleeve 21. A limiting sleeve 21 with an L-shaped corner hole can be provided on the connecting plate 4. The side holes of the L-shaped corner hole are aligned with the limiting sleeve 21 on the mounting plate 7, so that when the positioning rod 22 is inserted into the side hole of the limiting sleeve 21, it can restrict the mounting plate 7 to a horizontal state, and when the positioning rod 22 is inserted into the top hole of the limiting sleeve 21, it can restrict the mounting plate 7 to a vertical state, thereby preventing accidental rotation of the mounting plate 7.

[0031] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 The drive assembly includes a motor 6 and a winding reel 23. The motor 6 is fixedly mounted on the end of the mounting plate 7 away from the connecting plate 4. The winding reel 23 is coaxially fixed to the output shaft of the motor 6. The hoisting assembly is connected to the winding reel 23.

[0032] Preferably, the motor 6 can be a bidirectional rotating motor of the prior art, used to drive the winding wheel 23 to rotate in the forward or reverse direction, thereby lifting the hoisting component upward or lowering the building construction materials.

[0033] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 The mounting plate 7 is provided with a bearing seat 5 at the end away from the connecting plate 4. The bearing seat 5 is connected to the end of the winding wheel 23 away from the motor 6, so that the winding wheel 23 is rotatably mounted on the mounting plate 7.

[0034] The bearing housing 5 provides support for the winding wheel 23, ensuring its stable rotation.

[0035] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 The hoisting assembly includes a support arm 11, a fixed wheel 12, a wire rope 13, and a hook 14. One end of the support arm 11 is fixedly mounted on a rotating assembly, and the other end of the support arm 11 extends obliquely upward. The fixed wheel 12 is rotatably mounted on the other end of the support arm 11 via an axle. One end of the wire rope 13 is wound around a take-up wheel 23, and the other end of the wire rope 13 is wound around the fixed wheel 12 and connected to the hook 14. Building materials for construction are suspended on the hook 14.

[0036] Preferably, one end of the support arm 11 has an obtuse angle structure, and the extension angle and height of the support arm 11 can be adaptively adjusted according to the hoisting height requirements to ensure that the hoisting height meets the construction needs. The fixed pulley 12 can be a fixed pulley, used to position the wire rope 13 and facilitate the winding and release of the wire rope 13.

[0037] One end of the wire rope 13 is wound around the take-up reel 23. When the take-up reel 23 rotates in the forward direction, the wire rope 13 is wound up, thereby lifting the hook 14 and the building materials suspended on the hook 14. When the take-up reel 23 rotates in the reverse direction, the wire rope 13 is released, thereby lowering the hook 14 and the building materials suspended on the hook 14. Depending on the lifting requirements, the hook 14 can also be replaced with a hanging basket, etc.

[0038] When the motor 6 stops rotating, the winding wheel 23 can remain stationary, thus ensuring the tension on the wire rope 13 and preventing building materials from falling during construction, ensuring high safety.

[0039] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 The hoisting assembly also includes a positioning plate 8 and a rotating roller 9; a pair of positioning plates 8 are symmetrically fixed on both sides of one end of the support arm 11, and the rotating roller 9 is rotatably installed between the pair of positioning plates 8 via a roller shaft; and the height of the roller shaft 9 is lower than the height of the fixed wheel 12 and the height of the winding wheel 23, so that the wire rope 13 hangs down naturally after passing around the bottom of the roller shaft 9 and the top of the fixed wheel 12.

[0040] The positioning plate 8 and the rotating roller 9 guide and limit the wire rope 13, preventing it from slipping off the fixed pulley 12 and maintaining its tension, thereby improving the safety and stability of hoisting. As the wire rope 13 is wound or released, the rotating roller 9 rotates under the action of friction between itself and the wire rope 13, guiding its movement without causing wear.

[0041] Please see the appendix Figure 1 To be continued Figure 4 The rotating assembly includes a mounting base 3, a support rod 15, a crank handle 18, a worm gear 19, and a worm wheel 20. The mounting base 3 is fixedly installed on the top of the column 2. The two ends of the worm gear 19 are rotatably mounted in the mounting base 3 via rotating bearings. The worm wheel 20 is rotatably mounted in the mounting base 3 via a wheel axle, and the worm wheel 20 is meshed with the worm gear 19 for transmission. The lower end of the support rod 15 is coaxially fixed to the worm wheel 20. One end of the support arm 11 is fixedly installed on the upper end of the support rod 15. The connecting plate 4 is installed on the top side of the support rod 15. One end of the crank handle 18 is inserted into the mounting base 3 and coaxially fixed to one end of the worm gear 19. The other end of the crank handle 18 is located on the top side of the column 2.

[0042] Preferably, the crank handle 18 can be a Z-shaped crank handle, which can be manually controlled by the operator to drive the worm gear 19 to rotate in the forward or reverse direction.

[0043] When the worm gear 19 rotates in the forward or reverse direction, the meshing transmission worm wheel 20 rotates clockwise or counterclockwise in sync, thereby driving the support rod 15 to rotate clockwise or counterclockwise in sync. Then, the support rod 15 drives the connecting plate 4, mounting plate 7, drive assembly, and hoisting assembly installed on it to rotate synchronously, realizing the horizontal transportation of building materials for housing construction.

[0044] Preferably, the worm 19 and worm wheel 20 can be existing self-locking high-strength worm gear assemblies. The worm 19 can engage the worm wheel 20 under the drive of the crank handle 18. When the crank handle 18 is stopped, the worm teeth of the worm gear assembly achieve self-locking and can bear the weight of building materials, preventing them from falling during construction. Worm gear assemblies with self-locking functions are commonly used transmission mechanisms in this field, and their specific structure and working principle will not be described in detail here.

[0045] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 A support ring 24 is fixedly connected to the middle of the support rod 15, and a top rod 10 is connected between the support ring 24 and the middle of the support arm 11.

[0046] Preferably, the load of the support arm 11 is transferred to the support rod 15 through the top rod 10 and the support ring 24 to prevent the support arm 11 from bending, deforming or breaking.

[0047] Please see the appendix Figure 1 and attached Figure 2 The base 1 is provided with a counterweight 16, which is located on the side of the bottom of the column 2.

[0048] The weight of the counterweight 16 can be adjusted according to the lifting load to improve the placement stability of the base 1, thereby preventing the entire device from tipping over during lifting.

[0049] Please see the appendix Figure 1 and attached Figure 2 The base 1 and the column 2 are connected by a tie rod 17 at an angle, and the two tie rods 17 are symmetrically arranged on the front and rear sides of the counterweight 16.

[0050] By setting the tie rod 17, the installation reliability of the column 2 on the base 1 can be improved, the force transmission can be facilitated, and the load-bearing capacity of the column 2 can be improved.

[0051] Please see the appendix Figure 1The positioning rod 22 has an L-shaped structure. The mounting plate 7 is provided with a stop block 25. The distance between the limiting sleeve 21 on the mounting plate 7 and the stop block 25 is less than the length of the horizontal section of the positioning rod 22, so that when the horizontal section of the positioning rod 22 is movably inserted into the limiting sleeve 21, the vertical section of the positioning rod 22 can contact and connect with the stop block 25.

[0052] By setting the stop 25 and the limiting sleeve 21 on the mounting plate 7, the sliding range of the positioning rod 22 can be limited, preventing the positioning rod 22 from detaching from the mounting plate 7.

[0053] Please see the appendix Figure 1 To be continued Figure 4 The method of use and working principle of this utility model are as follows:

[0054] Preferably, the entire device can be made of high-strength materials such as steel, according to the weight of the building construction materials to be hoisted, so as to ensure that each component in the device has sufficient load-bearing capacity and can not deform or be damaged under stress.

[0055] The entire hoisting device is stably placed at the construction location via a base 1 with a counterweight 16, and the building construction materials to be hoisted are hung on the hook 14.

[0056] Start motor 6, which drives take-up reel 23 to rotate, causing wire rope 13 to be wound on take-up reel 23, thereby lifting the building construction materials to the designated height.

[0057] When the crank handle is turned 18, the positioning rod 22 is directed towards... Figure 1 Pulling the rod to the left, as shown, disengages the positioning rod 22 from the side hole of the upper limit sleeve 21 of the connecting plate 4, releasing the horizontal restriction on the mounting plate 7. This allows the mounting plate 7 to rotate upwards via the pin shaft. The mounting plate 7, rotated upwards to a vertical position, avoids the area where workers are located during rotation with the rotating assembly, thus preventing collisions. Inserting the positioning rod 22 downwards into the top hole of the upper limit sleeve 21 of the connecting plate 4 prevents the mounting plate 7 from rotating downwards and falling.

[0058] The worker manually turns the crank handle 18, which drives the worm gear 19 to rotate synchronously and engage the transmission worm wheel 20. The worm wheel 20 drives the support rod 15 to rotate synchronously, thereby causing the connecting plate 4, mounting plate 7, drive assembly, and hoisting assembly on the support rod 15 to rotate synchronously, rotating the building construction materials laterally to the designated position, and unloading the building construction materials from the hook 14, thus completing the hoisting of the building construction materials.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
