Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and more specifically, to a lifting device for solid wood furniture processing. Background Art

[0002] Solid wood furniture refers to furniture made of solid wood. Generally, solid wood furniture is divided into two types: pure solid wood furniture and all-solid wood furniture. Solid wood furniture is classified by wood species into beech, teak, maple, oak, red toon, ash, elm, poplar, pine, etc., among which beech, teak, and red toon are the most precious. The operation and development of China's solid wood furniture industry are in good condition. The Research Center of Zhiyan Data shows that with the continuous expansion of the operating demand market of China's solid wood furniture industry, the operation of China's solid wood furniture industry will usher in a new development opportunity.

[0003] Currently, during the production and processing operations of solid wood furniture, lifting operations need to be carried out on the solid wood furniture. At this time, during the lifting process of the solid wood furniture, there is a long-term acting force on the contact part between the lifting equipment and the solid wood furniture. At this time, since some structures of the solid wood furniture cannot withstand large supporting forces or tensile forces for a long time, it may be prone to the situation of being damaged by compression or tension. And the contact surface between the common lifting equipment and the solid wood furniture is relatively fixed, making it difficult to avoid the situation that some structures of the solid wood furniture are under long-term compression or tension.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure, and a lifting device for solid wood furniture processing is provided, with the expectation of achieving a more practical value purpose. Summary of the Invention

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] See also Figure 1 - Figure 7 A lifting device for solid wood furniture processing includes a large steel structure support 1. The large steel structure support 1 is a basic structure that can provide support for the entire device and ensure the stability of the entire device.

[0048] A lifting and hoisting assembly 2 and a fine material recovery assembly 3 are provided on the large steel structure support 1. A multi-contact surface support assembly 4 is provided below the lifting and hoisting assembly 2. The multi-contact surface support assembly 4 is used to provide support for solid wood furniture, and the contact area and position between the multi-contact surface support assembly 4 and the solid wood furniture can be changed multiple times to avoid long-term compression or tension on a certain part of the solid wood furniture. The lifting and hoisting assembly 2 is responsible for controlling the lifting and lifting of the multi-contact surface support assembly 4 and the solid wood furniture. The fine material recovery assembly 3 uses the negative pressure principle to absorb the fine materials that may appear in the lifting operation of the solid wood furniture.

[0049] The large steel structure support 1 includes a first gantry 101, a second gantry 102 and a steel beam 103. The first gantry 101 and the second gantry 102 have the same structure and are arranged parallel to each other. The two ends of the steel beam 103 are respectively fixed to the middle of the top of the first gantry 101 and the second gantry 102.

[0050] The first gantry 101 , the second gantry 102 and the steel beam 103 form a stable structure, and at the same time, ensure that there is sufficient working space between the first gantry 101 and the second gantry 102 .

[0051] The lifting and hoisting assembly 2 includes four cable winches 201 and four reduction motors 202. The cable winches 201 and the reduction motors 202 are respectively fixed on the first gantry 101 and the second gantry 102, and the reduction motors 202 and the cable winches 201 are matched one by one. The output end of the reduction motor 202 is connected to the central axis of the corresponding cable winch 201 through a coupling. Each cable winch 201 is wound with multiple strands of steel cables 203. The bottom ends of the two multiple strands of steel cables 203 are fixedly connected to the same work platform 204, and both ends of one of the work platforms 204 are slidably connected to the first gantry 101, and both ends of the other work platform 204 are slidably connected to the second gantry 102.

[0052] The reduction motor 202 controls the rotation of the cable winch 201, thereby controlling the winding or release of the multi-strand cable 203. When the four multi-strand cables 203 are wound or released synchronously, the corresponding working platform 204 rises or falls synchronously. At this time, it can drive the multi-contact surface support assembly 4 connected to the working platform 204 and the solid wood furniture in contact with the multi-contact surface support assembly 4 to change the height. The first gantry 101 and the second gantry 102 respectively limit the sliding direction of the working platform 204 at the corresponding positions, which can ensure the stable lifting of the working platform 204.

[0053] The fine material recovery assembly 3 includes an oil cylinder 301. The oil cylinder 301 is fixed at the center of the top end of the steel beam 103, and the output shaft of the oil cylinder 301 passes through the steel beam 103 and is fixedly connected with a large air hood 302. Long-distance air ducts 303 are fixed on both sides of the large air hood 302. A through hole 104 is provided on the steel beam 103, and high-suction pumps 304 are fixedly installed at the top ends of the first gantry 101 and the second gantry 102. Fine material storage bins 305 are fixedly installed on the sides of the first gantry 101 and the second gantry 102. The long-distance air ducts 303 pass through the through hole 104 and are connected to the high-suction pumps 304. The output ends of the high-suction pumps 304 are fixedly installed with short-distance air ducts 306, and the high-suction pumps 304 are connected to the fine material storage bins 305 through the short-distance air ducts 306.

[0054] During the lifting process of the solid wood furniture, the fine material recovery assembly 3 can be used to absorb the fine materials that may exist on the solid wood furniture. At this time, the oil cylinder 301 controls the large air hood 302 to descend. At the same time, the high-suction pump 304 operates. Cooperating with the long-distance air duct 303, suction is generated in the large air hood 302, and the fine materials scattered in the air sequentially follow the large air hood 302, the long-distance air duct 303, the high-suction pump 304, and the short-distance air duct 306, and are finally absorbed at the fine material storage bin 305 to achieve an environmental protection effect.

[0055] The multi-contact surface support assembly 4 includes a number of independent cylinders 401. The independent cylinders 401 are respectively fixed on the two working platforms 204 and are evenly distributed. The output ends of the independent cylinders 401 pass through the working platforms 204 and are fixedly connected with suspension rods 402. The bottom ends of the suspension rods 402 are fixedly connected with L-shaped connectors 403. Two symmetrically positioned L-shaped connectors 403 form a group, and a long rod 404 is fixed between the two L-shaped connectors 403.

[0056] Two L-shaped connectors 403 and a long rod 404 form a support member. Before lifting, the independent cylinder 401 controls the boom 402 to lower, and then controls the support member to lower to the lowest height. At this time, a support surface can be formed, which also facilitates moving the solid wood furniture onto the support surface. Then, the independent cylinder 401 is used to control the boom 402 to rise, and then controls the support member to rise to the highest height to complete the lifting operation of the solid wood furniture. Under the condition of keeping the support of the solid wood furniture stable, any independent cylinder 401 can be individually controlled to operate, causing the corresponding support surface to descend and releasing the force of the support surface on the solid wood furniture.

[0057] Embodiment 2:

[0058] Based on the above Embodiment 1, a further description is made.

[0059] Please refer to Figure 3 and Figure 4 , specifically, signal transceiver structures are provided inside all four reduction motors 202, and the four signal transceiver structures are controlled by synchronous signals.

[0060] Based on the above structure, the four reduction motors 202 can work synchronously, and further, the synchronous winding or release of the four multi-strand steel cables 203 can be realized.

[0061] , specifically, T-shaped sliders 2043 are fixedly installed at both ends of the workbench 204, and T-shaped chutes 1011 are provided on the inner sides of the first gantry 101 and the second gantry 102. The T-shaped sliders 2043 slide inside the T-shaped chutes 1011.

[0062] Based on the above structure, the T-shaped chutes 1011 can effectively limit the sliding direction of the T-shaped sliders 2043. At the same time, two T-shaped sliders 2043 are configured for one workbench 204, and the two T-shaped sliders 2043 slide synchronously and at the same frequency, which can effectively ensure the stable lifting of the workbench 204.

[0063] , specifically, between the inner top of the T-shaped chute 1011 and the top end of the T-shaped slider 2043, a long-distance spring rod 1012 is fixedly installed, and the long-distance spring rod 1012 always remains in a compressed state.

[0064] Based on the above structure, the workbench 204 and the T-shaped sliders 2043 rise or fall synchronously. When rising, they are tightened by the multi-strand steel cables 203 and pulled up. When descending, the multi-strand steel cables 203 are released, and under the elastic force of the long-distance spring rod 1012, it can ensure the stable descent of the workbench 204 and the T-shaped sliders 2043, preventing the T-shaped sliders 2043 from getting stuck in the T-shaped chutes 1011 and unable to slide.

[0065] Refer to Figure 5 and Figure 6, Specifically, high-position support frames 1031 are fixedly installed at both ends of the top of the steel beam 103. Two sliding rods 1032 are fixedly installed between the inner top of the high-position support frame 1031 and the steel beam 103. A pulley group 1033 with a bracket is slidably connected to the two sliding rods 1032. Two fixed pulleys are arranged on the pulley group 1033 with a bracket, and the two fixed pulleys are arranged side by side. The long-distance air duct 303 passes through the sides of the two fixed pulleys in sequence.

[0066] Based on the above structure, the pulley group 1033 with a bracket is beneficial for changing the direction of the long-distance air duct 303.

[0067] Specifically, a spring member 1034 is sleeved on the side of the sliding rod 1032 and located between the pulley group 1033 with a bracket and the steel beam 103. The spring member 1034 is in a compressed state.

[0068] Based on the above structure, the high-position support frame 1031 and the sliding rod 1032 limit the sliding range of the pulley group 1033 with a bracket. When the oil cylinder 301 controls the large wind hood 302 to descend, the spring member 1034 is further compressed, and the height of the pulley group 1033 with a bracket decreases. When the oil cylinder 301 controls the large wind hood 302 to descend, under the elastic force of the spring member 1034, the height of the pulley group 1033 with a bracket increases, avoiding the long-distance air duct 303 from being scattered, and further avoiding the influence of the long-distance air duct 303 on the work of other structures.

[0069] Specifically, the fine material storage box 305 is a sealed box structure with a sliding door, and an electrostatic ball is placed inside the fine material storage box 305.

[0070] Based on the above structure, the sliding door facilitates the regular removal of the fine materials on the electrostatic ball, and the electrostatic effect of the electrostatic ball facilitates the adsorption of the absorbed fine materials.

[0071] Refer to Figure 3 , Figure 4 and Figure 7 , Specifically, the number of independent cylinders 401 arranged on each working platform 204 is eleven, and two independent cylinders 401 located on two different working platforms 204 are taken as a group, and the operation is controlled by a synchronous signal.

[0072] Based on the above structure, the eleven independent cylinders 401 on the same working platform 204 are all controlled to operate by independent signals, while controlling the two independent cylinders 401 in the same group can ensure that the L-shaped connecting pieces 403 at both ends of the same long rod 404 rise or fall synchronously.

[0073] Specifically, a bayonet 2041 is opened on the side of the working platform 204, and the L-shaped connecting piece 403 is clamped with the bayonet 2041 when it rises to the highest height.

[0074] Based on the above structure, when the L-shaped connector 403 rises, it can drive the solid wood furniture to the highest height. At this time, by using the clamping of the bayonet 2041, the rising height of the L-shaped connector 403 and the long rod 404 can be limited, and at the same time, the situation of the L-shaped connector 403 and the long rod 404 shaking left and right can be avoided, ensuring the stable support of the solid wood furniture during the entire lifting process.

[0075] Specifically, a baffle 2042 is fixedly installed at the bottom end of the operating table 204. When the L-shaped connector 403 rises to the highest height, the upper end surface of the L-shaped connector 403 contacts the lower end surface of the baffle 2042.

[0076] Based on the above structure, when the solid wood furniture is lifted, it can prevent fine materials from scattering and adhering to the output shaft of the independent cylinder 401 to a certain extent, thereby avoiding the problem that the independent cylinder 401 cannot operate.

[0077] Working principle:

[0078] When performing the lifting operation of the solid wood furniture, use this device for the operation.

[0079] First, use the multi-contact surface support component 4 to support the solid wood furniture. Specifically, two L-shaped connectors 403 and a long rod 404 form a support member. Before lifting, the independent cylinder 401 controls the boom 402 to descend, and then controls the support member to descend to the lowest height. At this time, a support surface can be formed. Move the solid wood furniture onto the support surface, and then use the independent cylinder 401 to control the boom 402 to rise, and then control the support member to rise to the highest height.

[0080] Then, use the lifting and hoisting component 2 to perform the lifting operation. Specifically, the reduction motor 202 controls the rotation of the cable winch 201, and then controls the winding of the multi-strand cable 203. The synchronous winding of the four multi-strand cables 203, combined with the sliding limit of the T-shaped slider 2043 by the T-shaped chute 1011, realizes the synchronous elevation of the corresponding operating table 204. At this time, it can drive the multi-contact surface support component 4 connected to the operating table 204 and the solid wood furniture in contact with the multi-contact surface support component 4 to rise until the required height is reached.

[0081] Then, if further operations on the solid wood furniture are required, or to maintain the lifting height of the solid wood furniture, the height of the solid wood furniture can be adjusted multiple times by using the lifting and hoisting component 2. At the same time, control the eleven groups of independent cylinders 401 to work alternately, so that different long rods 404 contact the solid wood furniture alternately, ensuring the stable support of the long rod 404 for the solid wood furniture. At the same time, it effectively avoids the situation that some structures of the solid wood furniture are under long-term compression or tension.

[0082] Meanwhile, during the lifting process, if there are fine materials, the fine material recovery component 3 is used for recovery. Specifically, the oil cylinder 301 controls the large air hood 302 to descend. At the same time, the high suction pump 304 operates, cooperating with the long-distance air duct 303, to generate suction in the large air hood 302. The fine materials sequentially follow the large air hood 302, the long-distance air duct 303, the high suction pump 304, and the short-distance air duct 306, and are finally absorbed at the fine material storage box 305.

[0083] When completing a lifting operation of solid wood furniture, the lifting and hoisting component 2 is used to lower the height of the multi-contact surface support component 4 and the solid wood furniture, and then the height of the long rod 404 in the multi-contact surface support component 4 is reduced to lower the height of the solid wood furniture to the lowest, and then the solid wood furniture can be unloaded.

[0084] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
