Description

Technical Field

[0001] This invention relates to the field of electric lifting platform assembly technology, specifically a support-type assembly device for electric lifting platform components. Background Technology

[0002] Electric lifting platforms are mechanical devices used for vertical transportation of goods or personnel, widely used in warehousing, logistics, construction, and industrial production lines. Electric lifting platforms achieve their lifting function through a scissor-lift telescopic structure. However, during the assembly of this structure, which consists of multiple intersecting scissor components, existing assembly devices are inconvenient for simultaneously assembling and adjusting multiple scissor components in the same group. This results in a small number of components being assembled at a time, low assembly efficiency, and increased difficulty in maintaining a secure fit as the scissor components are gradually assembled and raised. Therefore, to address these issues, a support-type assembly device for electric lifting platform components is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a support-type assembly device for electric lifting platform components in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a support-type assembly device for electric lifting platform components, comprising two sets of scissor lift component placement frames, an adjustment mechanism, and a traction connection mechanism. The position distribution of each scissor lift component placement frame in each set is adjusted by a lead screw. The two sets of scissor lift component placement frames are adjusted to be intersecting by the adjustment mechanism. The two intersecting sets of scissor lift component placement frames are brought closer together by a moving component. The two ends of the U-shaped rod in the traction connection mechanism are connected to the back of the corresponding scissor lift component placement frame. The internally threaded short pipe in the traction connection mechanism is threadedly connected to the lead screw.

[0005] Preferably, the modulation mechanism includes a magnetic sliding block, longitudinal guide rails, and a first hydraulic cylinder. The top ends of the two longitudinal guide rails are rotatably connected to two bearing seats via short shafts, and the top of each bearing seat is fixedly connected to the output end of the first hydraulic cylinder. A set of magnetic sliding blocks is slidably installed on each of the two longitudinal guide rails, and a lateral displacement compensation sliding block is rotatably connected to the back of each magnetic sliding block via a rotating shaft. The two lateral displacement compensation sliding blocks located horizontally opposite each other are slidably connected to two short guide rails located on the back of the same scissor lift discharge frame.

[0006] Preferably, the magnetic slide is magnetically fixed to the longitudinal guide rail, and the longitudinal guide rail is made of magnetically adsorbable metal material, wherein the magnetic slide is an electromagnet structure.

[0007] Preferably, the cylinder body of the first hydraulic cylinder is fixedly mounted on the end of the E-shaped plate, and a motor is mounted on the L-shaped plate connected to the bottom side of the E-shaped plate, with the shaft end of the motor connected to one end of the lead screw.

[0008] Preferably, the traction connection mechanism further includes a dual-purpose lever and a block. The middle part of the block is rotatably connected to the middle part of the internally threaded short pipe through a bearing, and the dual-purpose lever is installed on the surface of the internally threaded short pipe. One end face of the block is rotatably connected to the middle part of the U-shaped rod through a rotating shaft.

[0009] Preferably, the dual-purpose levers are in groups of multiple, and one end of each dual-purpose lever is concentrated at the same point.

[0010] Preferably, the U-shaped rod is rotatably connected to the end of the cylinder body of the third cylinder, and the output end of the third cylinder extends through the central hole located in the middle of the scissor lift frame.

[0011] Preferably, the moving component includes a lateral slide and a transverse guide rail. Two lateral slides in the same group are fixedly installed at both ends of the same E-shaped plate, and the lateral slides are slidably installed on the transverse guide rail, which is fixed above the ground by hoisting.

[0012] Preferably, a second hydraulic cylinder is installed at the bottom end of the lead screw, and the output end of the second hydraulic cylinder extends to contact the ground.

[0013] Preferably, the scissor lift assembly is fixed inside the scissor lift assembly frame by a third hydraulic cylinder, and the scissor lift assembly has a central connecting hole in the middle.

[0014] The beneficial effects of this invention are: it can quickly and synchronously adjust a set of scissor lift frames to a consistent tilting state, and each scissor lift is bound within each scissor lift frame. At the same time, by using a traction method, two sets of scissor lift frames can be combined together, which is beneficial to forming multiple intersection points of the scissor lifts. Moreover, the central connecting holes located in the middle of the scissor lifts coincide, which facilitates the installation of connecting shafts. By placing the scissor lifts from bottom to top in a set of interconnected scissor lift frames, a support assembly structure can be formed to synchronously adjust multiple scissor lifts in the same group to a tilting state. The assembly efficiency is high and the operation is safe. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Please see Figure 1-7As shown, a support-type assembly device for components of an electric lifting platform includes two sets of scissor lift release frames 1, an adjustment mechanism, and a traction connection mechanism 4. The position distribution of each scissor lift release frame 1 in each set is adjusted by the action of a lead screw 2. The two sets of scissor lift release frames 1 are adjusted to be cross-shaped by the adjustment mechanism. The two sets of scissor lift release frames 1 that are cross-shaped are brought closer together by a moving component. The two ends of the U-shaped rod 410 located in the traction connection mechanism 4 are connected to the back of the corresponding scissor lift release frame 1. The internally threaded short pipe 420 located in the traction connection mechanism 4 is threadedly connected to the lead screw 2.

[0022] The modulation mechanism includes a magnetic sliding block 140, a longitudinal guide rail 3, and a first hydraulic cylinder 6. The top ends of the two longitudinal guide rails 3 are rotatably connected to two bearing seats 5 via short shafts, and the top of each bearing seat 5 is fixedly connected to the output end of the first hydraulic cylinder 6. A set of magnetic sliding blocks 140 is slidably installed on each of the two longitudinal guide rails 3, and a lateral displacement compensation sliding block 130 is rotatably connected to the back of each magnetic sliding block 140 via a rotating shaft. The two lateral displacement compensation sliding blocks 130 located horizontally opposite each other are slidably connected to two short guide rails 120 located on the back of the same scissor lift frame 1. The magnetic sliding block 140 is magnetically fixed on the longitudinal guide rail 3, and the longitudinal guide rail 3 is made of magnetically pleasing metal material. The magnetic sliding block 140 is an electromagnet structure. The cylinder body of the first hydraulic cylinder 6 is fixedly installed at the end of the E-type plate 7, and a motor 721 is installed on the L-type plate 720 connected to the bottom side of the E-type plate 7. The shaft end of the motor 721 is connected to one end of the lead screw 2. The scissor fork discharge frame 1 is fixed with a scissor fork 10 through the third hydraulic cylinder 9, and a central connecting hole 10a is opened in the middle of the scissor fork 10. like Figure 3 , Figure 4 and Figure 7 As shown, based on the scissor lift 10 placed inside each scissor lift frame 1, the following operations are performed: First, the magnetic slide 140 magnetically fixes the longitudinal guide rail 3 made of magnetic metal in the form of an electromagnetic magnetic field. Then, two first cylinders 6 are operated, one first cylinder 6 extends and the other first cylinder 6 retracts, pushing and pulling the longitudinal guide rail 3 connected to each other respectively. Combined with the rotational connection between each magnetic slide 140 and the lateral displacement compensation slide 130 located on the short guide rail 120, the scissor lift frame 1 and the U-shaped rod 410 are in a lateral tilt state. Finally, the two sets of scissor lift frames 1 in the lateral tilt state in opposite directions are moved together. The advantages are: it can quickly and synchronously adjust a set of scissor lift frames 1 to a consistent tilt state, and each scissor lift 10 is bound in each scissor lift frame 1. At the same time, it can combine two sets of scissor lift frames 1 together by means of traction, which is conducive to forming multiple intersection points of scissor lift 10. The central connecting hole 10a located in the middle of the scissor lift 10 coincides, which is convenient for installing connecting shafts. By placing scissor lift components 10 from bottom to top in a set of interconnected scissor lift component placement frames 1, a support assembly structure can be formed that synchronously adjusts multiple scissor lift components 10 in the same group to an inclined state. This structure offers high assembly efficiency and strong operational safety.

[0023] The traction connection mechanism 4 also includes a dual-purpose lever 421 and a block 430. The middle part of the block 430 is rotatably connected to the middle part of the internally threaded short pipe 420 through a bearing, and the dual-purpose lever 421 is installed on the surface of the internally threaded short pipe 420. One end face of the block 430 is rotatably connected to the middle part of the U-shaped rod 410 through a rotating shaft. The dual-purpose lever 421 is in a group of multiple, and one end of each dual-purpose lever 421 is concentrated at the same point. like Figure 2 , Figure 3 and Figure 5 As shown, the assembler can use one hand or a special tool to bind one end of the dual-purpose lever 421, which is all concentrated in one place, together. At this time, the motor 721 drives the lead screw 2 to rotate, and the height of a set of scissor lift frames 1 connected by the traction connection mechanism 4 can be adjusted. When the initial height adjustment of the scissor lift assembly frame 1 is completed, the lead screw 2 is fixed. The horizontal push-pull lever 421, which is moved horizontally from top to bottom or bottom to top, rotates the corresponding internal threaded short tubes 420 along the lead screw 2, so as to distribute the multiple internal threaded short tubes 420 in the set at equal or unequal intervals on the lead screw 2. This further links the scissor lift assembly frame 1 to be distributed at equal or unequal intervals, providing convenience for the subsequent connection operation between the ends of the scissor lift 10.

[0024] The U-shaped rod 410 is rotatably connected to the cylinder end of the third oil cylinder 9, and the output end of the third oil cylinder 9 extends through the central hole 110 located in the middle of the scissor lift frame 1. By extending the third hydraulic cylinder 9, its output end is inserted through the central hole 110 into the central connecting hole 10a located in the middle of the scissor lift 10, thereby binding the scissor lift 10 inside the scissor lift discharge frame 1.

[0025] The moving component includes a lateral slide block 710 and a transverse guide rail 711. Two lateral slide blocks 710 of the same group are fixedly installed at both ends of the same E-shaped plate 7, and the lateral slide blocks 710 are slidably installed on the transverse guide rail 711, which is fixed above the ground by hoisting.

[0026] like Figure 1 As shown, a second hydraulic cylinder 8 is installed at the bottom of the lead screw 2, and the output end of the second hydraulic cylinder 8 extends and contacts the ground. By extending and contacting the ground, the output end of the second hydraulic cylinder 8 serves to constrain the lead screw 2 and prevent the lead screw 2 from shaking during rotation.

[0027] When using this invention, as Figure 2 , Figure 3 and Figure 5 As shown, the assembler can use one hand or a special tool to bind one end of the dual-purpose lever 421, which is all concentrated in one place, together. At this time, the motor 721 drives the lead screw 2 to rotate, and the height of a set of scissor lift frames 1 connected by the traction connection mechanism 4 can be adjusted. When the initial height adjustment of the scissor lift assembly frame 1 is completed, the lead screw 2 is fixed. The horizontal push-pull lever 421 from top to bottom or bottom to top rotates the corresponding internal threaded short tubes 420 along the lead screw 2, so as to distribute the multiple internal threaded short tubes 420 in the set at equal or unequal intervals on the lead screw 2. This further links the scissor lift assembly frame 1 to be distributed at equal or unequal intervals, providing convenience for the subsequent connection operation between the ends of the scissor lift assembly 10. like Figure 3 , Figure 4 and Figure 7 As shown, based on the scissor lift 10 placed inside each scissor lift frame 1, the following operations are performed: First, the magnetic slide 140 magnetically fixes the longitudinal guide rail 3 made of magnetic metal in the form of an electromagnetic magnetic field. Then, two first cylinders 6 are operated, one first cylinder 6 extends and the other first cylinder 6 retracts, pushing and pulling the longitudinal guide rail 3 connected to each other respectively. Combined with the rotational connection between each magnetic slide 140 and the lateral displacement compensation slide 130 located on the short guide rail 120, the scissor lift frame 1 and the U-shaped rod 410 are in a lateral tilt state. Finally, the two sets of scissor lift frames 1 in the lateral tilt state in opposite directions are moved together. The advantages are: it can quickly and synchronously adjust a set of scissor lift frames 1 to a consistent tilt state, and each scissor lift 10 is bound in each scissor lift frame 1. At the same time, it can combine two sets of scissor lift frames 1 together by means of traction, which is conducive to forming multiple intersection points of scissor lift 10. The central connecting hole 10a located in the middle of the scissor lift 10 coincides, which is convenient for installing connecting shafts. By placing scissor lift components 10 from bottom to top in a set of interconnected scissor lift component placement frames 1, a support assembly structure can be formed that synchronously adjusts multiple scissor lift components 10 in the same group to an inclined state. This structure offers high assembly efficiency and strong operational safety.
