[0002] In renovation projects, material lifting devices are crucial for ensuring efficiency and safety. Common types of material lifting devices include electric hanging baskets, small material hoists, and electric hoists. Electric hoists primarily consist of an electric motor and a drum or sprocket.

[0042] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] Reference Figures 1 to 7 As shown, the present invention provides a material lifting device for decoration engineering, including: a guide rail 1, a roller 2, a heat dissipation cylinder 3, and a first transmission structure 4.

[0045] The guide rail 1 has an I-shaped cross section. The guide rail 1 is slidably provided with a sliding seat 11. A slide groove is formed on the top of the slide seat 11. The guide rail 1 is slidably provided in the slide groove, and the shape of the cross section of the slide groove is adapted to the shape of the cross section of the guide rail 1.

[0046] The roller 2 is rotatably mounted on a sliding seat 11. A motor 21 is mounted on the sliding seat 11. The output shaft of the motor 21 is coaxially connected to one end of the roller 2. A steel wire rope 22 for hoisting materials is wound around the roller 2.

[0047] When in use, the motor 21 drives the roller 2 to rotate to retract and release the steel wire rope 22 .

[0048] In this embodiment, a cooling groove 20 is formed at the other end of the roller 2. Cooling liquid, such as water, is contained in the cooling groove 20. The cooling liquid is annular and coaxial with the roller 2, allowing the cooling groove 20 to radiate heat over a larger area of ​​the roller 2.

[0049] The heat dissipation tube 3 is mounted on the sliding seat 11. One end of the heat dissipation tube 3 is attached to the other end of the roller 2. An outlet 3a and an inlet 3b are formed on the end surface of one end of the heat dissipation tube 3. Outlet 3a and inlet 3b are connected to the cooling tank 20. Check valves 32 are installed in each of the outlet 3a and inlet 3b. A piston plate 31 slides inside the heat dissipation tube 3. A cavity is formed between the piston plate 31 and one end of the heat dissipation tube 3. The cavity is filled with coolant.

[0050] The first transmission structure 4 is mounted on the roller 2. It is connected between the piston plate 31 and the roller 2, causing the piston plate 31 to reciprocate along the axial direction of the heat sink 3. This linear reciprocating motion of the piston plate 31 changes the pressure within the cavity. When the piston plate 31 moves away from the roller 2, the pressure within the cavity decreases. Conversely, when the piston plate 31 moves closer to the roller 2, the pressure within the cavity increases.

[0051] Specifically, after the pressure in the heat dissipation tube 3 decreases, the coolant in the cooling tank 20 is discharged into the heat dissipation tube 3 through the check valve 32 at the outlet 3a. After the pressure in the heat dissipation tube 3 increases, the coolant in the heat dissipation tube 3 is discharged into the cooling tank 20 through the check valve 32 at the inlet 3b.

[0052] As a preferred embodiment, the heat dissipation tube 3 is cylindrical and is coaxially arranged with the roller 2. The heat dissipation tube 3 is a heat-conducting metal tube.

[0053] In some embodiments, a plurality of heat dissipation fins are formed on the exterior of the circumferential sidewall of the heat-conducting metal cylinder. These fins are spaced apart along the circumference of the heat-conducting metal cylinder. The coolant within the heat dissipation cylinder 3 exchanges heat with the outside world via the heat dissipation cylinder 3, thereby reducing the temperature of the coolant within the heat dissipation cylinder 3.

[0054] Combine Figure 1 and Figure 2 As shown, a protective cylinder 12 is mounted at the bottom of the sliding seat 11. The roller 2 is rotatably mounted within the protective cylinder 12. The protective cylinder 12 is cylindrical and coaxial with the roller 2. The motor 21 and the heat sink 3 are mounted at opposite ends of the protective cylinder 12. The sidewalls of the protective cylinder 12 are perforated. A steel wire rope 22 is movably inserted through the perforations.

[0055] In this embodiment, a strip-shaped hole is formed in the side wall of the protective tube 12. The strip-shaped hole is arranged along the axial direction of the protective tube 12. A slide plate 13 is slidably arranged in the strip-shaped hole. The slide plate 13 is formed with a perforation.

[0056] As a preferred embodiment, the first transmission structure 4 includes a rotating shaft 41 , a pushing strip 42 , and a radial shaft 43 .

[0057] Specifically, a rotating shaft 41 is rotatably disposed within the heat dissipation cylinder 3. One end of the rotating shaft 41 is coaxially connected to the other end of the roller 2. A through hole is formed in the piston plate 31. The middle portion of the rotating shaft 41 is rotatably inserted into the through hole. A seal is installed between the through hole and the rotating shaft 41. The seal is a rubber gasket or other type of seal.

[0058] The other end of the heat dissipation tube 3 has a through hole. A push strip 42 slides into the through hole. One end of the push strip 42 is connected to the piston plate 31. The push strip 42 has a waist-shaped hole extending along the width of the push strip 42.

[0059] A radial shaft 43 is rotatably mounted within the heat dissipation tube 3. One end of the radial shaft 43 is connected to the other end of the rotating shaft 41 via a gear mechanism. The other end of the radial shaft 43 is connected to a toggle lever 44 via a first support rod. The toggle lever 44 slides within the waist-shaped hole. The length of the waist-shaped hole is greater than the outer diameter of the toggle lever 44. Within the waist-shaped hole, the toggle lever 44 can rotate and move along the length of the waist-shaped hole.

[0060] In this embodiment, the gear structure of the first transmission structure 4 includes a first bevel gear 45 and a second bevel gear 46 .

[0061] The first bevel gear 45 is coaxially connected to the rotating shaft 41 . The second bevel gear 46 is coaxially connected to the radial shaft 43 and meshes with the first bevel gear 45 .

[0062] Combine Figure 3 and Figure 4 As shown, two guide wheels 6 are rotatably mounted within the heat dissipation cylinder 3. The positions of the two guide wheels 6 correspond to the positions of the inlet 3b and outlet 3a. The other end of the rotating shaft 41 is connected to the guide wheels 6 via a second transmission structure 5. The rotation of the guide wheels 6 improves the efficiency of coolant flow through the inlet 3b and outlet 3a.

[0063] In this embodiment, the second transmission structure 5 includes a driven shaft 51 , an active plate 52 , a driven plate 53 and a transmission plate 54 .

[0064] Specifically, the driven shaft 51 is rotatably mounted on the end surface of the other end of the heat dissipation cylinder 3. The driven shaft 51 is arranged in the same direction as the axle 61 of the guide wheel 6, and one end of the driven shaft 51 is drivingly connected to the other end of the rotating shaft 41. The active plate 52 is arranged in the radial direction of the driven shaft 51. The active plate 52 is connected to the other end of the driven shaft 51. The driven plate 53 is arranged in the radial direction of the axle 61. The driven plate 53 is connected to the axle 61. The two ends of the transmission plate 54 are respectively pivotally connected to the active plate 52 and the driven plate 53.

[0065] The material lifting device for decoration engineering of the present invention is constructed by arranging a receiving groove in the roller 2 and combining the heat dissipation cylinder 3 and the piston plate 31 to form a circulating water cooling mechanism.

[0066] The operation of the motor 21 drives the ejector plate 42 and the piston plate 31 to move as a whole. When the pressure in the heat dissipation tube 3 increases, the piston plate 31 pushes the coolant through the check valve 32 at the inlet 3b and into the storage tank. When the pressure in the heat dissipation tube 3 decreases, the piston plate 31 drives the coolant through the check valve 32 at the outlet 3a, withdrawing the coolant from the storage tank and returning it to the original state. This forms a coolant circulation process to reduce the temperature of the roller 2.

[0067] In this embodiment, a wire rope 22 is wound around the surface of the roller 2, a slide plate 13 is slidably connected to a strip-shaped hole on the front of the protective cylinder 12, and a hook is provided at the end of the wire rope 22. The rotation of the roller 2 drives the wire rope 22 to reel and unreel on the surface of the roller 2, thereby driving the hook to lift the material.

[0068] like Figure 6 and Figure 7 As shown, the check valve 32 at the inlet 3b includes a water inlet valve pipe, a one-way valve ball, an elastic member and a blocking block.

[0069] The water inlet valve pipe is fixedly installed in the inlet 3b at one end of the heat dissipation tube 3. The one-way valve ball can be installed in the water inlet valve pipe so as to be movably along the axial direction of the water inlet valve pipe. The one-way valve ball is elastically connected to the inner wall of the water inlet valve pipe through an elastic member (such as a spring). The blocking block is fixed inside the water inlet valve pipe. The blocking block is provided with a through hole. The one-way valve ball is arranged on the side of the through hole of the blocking block close to the roller 2. The size of the through hole is smaller than the outer diameter of the one-way valve ball. The elastic force of the elastic member will push the one-way valve ball to seal the through hole of the blocking block, so that the coolant can only enter the accommodating groove of the roller 2 through the water inlet valve pipe in one direction when the one-way valve ball is pushed toward the roller 2.

[0070] Correspondingly, the check valve 32 at the outlet 3a will push the one-way valve ball to move toward the side close to the roller 2 under the elastic force of the elastic member, and will be blocked and restricted by the blocking block, so that the coolant can only push the one-way valve ball to move toward the side close to the heat dissipation tube 3 through the drain valve pipe, so that the coolant in the accommodating groove of the roller 2 can only flow back to the heat dissipation tube 3 through the drain valve pipe.

[0071] In this embodiment, two through holes are formed on the other end surface of the heat dissipation tube 3. The two through holes are respectively arranged on opposite sides of the rotating shaft 41. The piston plate 31 is driven to move in the heat dissipation tube 3 by two symmetrically arranged push strips.

[0072] In this embodiment, if Figure 4As shown, a main gear is rotatably mounted on the exterior of the heat dissipation cylinder 3. Auxiliary gears are coaxially connected to the axles 61 of the two guide water wheels 6. The auxiliary gears mesh with the main gears. One end of the driven plate 53 is fixedly connected to the axles of the main gears. The other end of the driven plate 53 is pivotally connected to one end of the transmission plate 54. Driven by the main and auxiliary gears, the two guide water wheels 6 rotate in opposite directions, assisting the coolant in passing through the inlet and outlet 3a of the heat dissipation cylinder 3.

[0073] The working principle and use process of the material lifting device for decoration engineering of the present invention are as follows:

[0074] First, by running the motor 21, the roller 2 can be driven to rotate so that the wire rope 22 wound on the surface of the unwinding roller 2 can be directed downward, and the position of the hook can be positioned and guided by the slide 13, and then the wire rope 22 can be unwound to drive the hook downward to hook the material for subsequent lifting.

[0075] The operation of the motor 21 transfers heat to the roller 2, causing the coolant inside the roller 2 to slowly heat up, and the rotation of the roller 2 drives the rotating shaft 41 to rotate. Then, due to the meshing relationship between the surface of the first bevel gear 45 and the second bevel gear 46 of the radial shaft 43, the radial shaft 43 and the first support rod are driven to rotate, and then the toggle rod 44 is caused to rotate and slide in the waist-shaped hole of the push strip 42, so as to drive the piston plate 31 to move back and forth left and right.

[0076] As the piston plate 31 moves closer to the inlet valve tube, it pushes the coolant, squeezing the one-way valve ball to open inlet 3b, allowing the coolant to flow through the inlet valve tube into the roller 2's receiving groove in one direction. As the piston plate 31 moves away from the drain valve tube, the amount of coolant in the roller 2's receiving groove increases, squeezing the one-way valve ball at outlet 3a to open outlet 3a, allowing the coolant to flow back into the heat sink 3. The coolant in the heat sink 3 cools down after exchanging heat with the outside world. After the coolant circulates, the roller 2 is cooled.

[0077] At the same time, the rotating shaft 41 rotates the guide water wheel 6 via the second transmission structure 5. The guide water wheel 6 at the inlet 3b helps guide the coolant through the check valve 32 at the inlet 3b and into the receiving groove of the roller 2. The guide water wheel 6 at the outlet 3a drives the coolant in the receiving groove of the roller 2 to flow back through the check valve 32 at the outlet 3a.

[0078] When the material lifting device for decoration projects of the present invention drives the roller 2 to rotate for lifting operations through the operation of the motor 21, the roller 2 will drive the piston plate 31 through the first transmission structure 4 to change the pressure in the heat dissipation tube 3, thereby realizing the back and forth circulation of the coolant between the heat dissipation tube 3 and the accommodating groove of the roller 2, so that the circulating coolant absorbs heat and cools the roller 2 as a whole, thereby increasing the service life of the wire rope 22 and ensuring the subsequent lifting effect.

[0079] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
