Description

Technical Field

[0001] This application relates to the field of lifting tools technology, and more particularly to lifting and transferring equipment. Background Technology

[0002] Current lifting tools generally consist of a support section and a lifting section. The lifting section is often a cylinder or a screw-slider mechanism. The support section is directly mounted on the telescopic rod of the cylinder or the slider of the screw-slider mechanism. The extension length of the telescopic rod or the rising distance of the slider is the lifting distance of the support section. Clearly, this type of lifting tool has a relatively poor lifting effect. Furthermore, if a higher lifting height is required, the telescopic rod of the cylinder needs to extend very long and a large amount of fluid needs to be introduced into the cylinder body, or the screw of the screw-slider mechanism needs to be designed to be very long and the number of rotations required to move the slider needs to be large. This results in a large overall size of the lifting tool, occupying a significant amount of space, and being very time-consuming to use.

[0003] In addition, when the lifting part is a cylinder, the supporting part is usually placed at the top of the telescopic rod. This makes the initial position of the supporting part relatively high, which increases the difficulty and effort of transferring objects to the supporting part and reduces the ease of use.

[0027] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0028] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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, the above terms should not be construed as limitations on this application.

[0029] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0030] refer to Figures 1 to 2 A preferred embodiment of the lifting and transferring device according to this application will be described in detail below. The lifting and transferring device includes a mounting frame 10 and a support member 20, the support member 20 being slidably mounted on the mounting frame 10. The support member 20 is used to support items.

[0031] The lifting and transferring device further includes a lifting device 30 and at least one connecting mechanism 40. The connecting mechanism 40 includes a rotating member 41 and a connecting member 42. The rotating member 41 is rotatably mounted on the lifting device 30. The connecting member 42 is wrapped around the rotating member 41 in a manner that it is attached to the upper surface of the rotating member 41, and its two ends are respectively connected to the mounting frame 10 and the support member 20. The lifting device 30 is configured to drive the rotating member 41 to rise and fall, so that the rotating member 41 drives the support member 20 to rise and fall through the connecting member 42, thereby transferring the item carried by the support member 20 vertically.

[0032] When the lifting device 30 drives the rotating member 41 to rise, the length of the connecting member 42 between its connection point with the mounting bracket 10 and the rotating member 41 increases, and the length of the connecting member 42 between its connection point with the support member 20 and the rotating member 41 decreases. The rising distance of the support member 20 is twice the rising distance of the rotating member 41, that is, the rising distance of the support member 20 is the sum of the rising distance of the rotating member 41 and the shortened length of the connecting member 42 between its connection point with the support member 20 and the rotating member 41, while the rising distance of the rotating member 41 is equal to the shortened length of the connecting member 42 between its connection point with the support member 20 and the rotating member 41.

[0033] In this way, by slightly moving the rotating component 41 upwards, the object supported by the support component 20 can be significantly lifted, achieving rapid lifting. Compared to directly driving the support component 20, this effectively improves the lifting effect and saves time and effort. Furthermore, through the coordinated action of the support component 20, the lifting device 30, and the connecting mechanism 40, the position of the support component 20 can be designed to be as low as possible before lifting. Compared to directly driving the support component 20 up and down, this effectively avoids situations where the initial position is too high, making it difficult to move the object to the support component 20. This reduces the difficulty of object placement, saves time, and increases ease of use.

[0034] Preferably, two connecting mechanisms 40 are provided. The rotating parts 41 of the two connecting mechanisms 40 are spaced apart from each other on the lifting device 30, and the connecting parts 42 of the two connecting mechanisms 40 are connected to one end of the support member 20 and are symmetrically distributed around the centerline of the support member 20. The lifting device 30 drives the support member 20 to rise and fall through the two connecting mechanisms 40, so that the support member 20 is subjected to uniform force and the stability of the rise and fall of the support member 20 is improved.

[0035] Preferably, the rotating member 41 is implemented as a gear, the connecting member 42 is implemented as a chain, and the lifting device 30 pushes the gear and drives the supporting member 20 to be lifted through the meshing of the gear and the chain.

[0036] As deformable, the rotating member 41 is implemented as a turntable, the connecting member 42 is implemented as a belt, and the lifting device 30 pushes the turntable and drives the supporting member 20 to be lifted through the frictional engagement between the turntable and the belt.

[0037] refer to Figure 1Furthermore, the support member 20 includes a support body 21 and at least one sliding part 22, the sliding part 22 being mounted on the support body 21. The mounting bracket 10 has at least one vertically arranged slide groove 101, and the support body 21 moves up and down in a direction parallel to the extending direction of the slide groove 101 such that the sliding part 22 engages with the slide groove 101.

[0038] Preferably, the sliding part 22 is rotatable. The sliding part 22 slides in the slide groove 101 with its peripheral wall abutting against the opposite side walls of the slide groove 101. It rotates by rubbing against the opposite side walls of the slide groove 101 during sliding, so as to reduce the friction between the support member 20 and the mounting frame 10 when the support member 20 is raised and lowered, thereby reducing wear and tear and improving service life.

[0039] Preferably, two sliding parts 22 are provided, and the number of sliding grooves 101 is the same as the number of sliding parts 22. The two sliding parts 22 are symmetrically distributed about the centerline of the supporting body 21, and each sliding part 22 is slidably disposed in one of the sliding grooves 101 to increase the stability of the supporting body 21 during lifting.

[0040] Furthermore, the upper surface of the supporting body 21 is at least partially sunken to form a concave surface 2101, and the object is supported by the supporting member 20 in such a way that it corresponds at least partially to the concave surface 2101 to prevent the object from rolling during lifting and lowering.

[0041] Preferably, the concave surface 2101 is arc-shaped to fit the peripheral wall of the columnar object, thereby improving the stability of lifting the corresponding object.

[0042] In one embodiment, the lifting device 30 is implemented as a cylinder, which is configured to extend and retract vertically to drive the rotating member 41 to rise and fall.

[0043] In another embodiment, the lifting device 30 is implemented including a lead screw and a slider. The lead screw is rotatably and vertically mounted on the mounting frame 10. The slider is threadedly connected to the lead screw and is configured to slide along the mounting frame 10 in a manner parallel to the extension direction of the slide groove 101. The rotating member 41 is rotatably mounted on the slider. Rotation of the lead screw causes the slider to rise and fall, thereby causing the rotating member 41 to rise and fall.

[0044] refer to Figures 2 to 9Preferably, the lifting device 30 includes a lifting seat 31, which includes a main body 311 and an inner body 312. The inner body 312 is installed inside the main body 311, and at least a portion of its outer peripheral wall forms an oil cavity 3101 together with the inner wall of the main body 311. The main body 311 has a pressure-drawing cavity 31101 and an oil guide channel 31102 with both ends communicating with the oil cavity 3101 and the pressure-drawing cavity 31101, respectively. Hydraulic oil in the oil cavity 3101 can be introduced into the pressure-drawing cavity 31101 through the oil guide channel 31102.

[0045] The built-in body 312 has a movable cavity 31201 with a predetermined length in the vertical direction. The seat body 311 also has an oil guide channel 31103 with both ends communicating with the movable cavity 31201 and the pressure chamber 31101, respectively. Hydraulic oil in the pressure chamber 31101 can be introduced into the movable cavity 31201 through the oil guide channel 31103. The lifting device 30 includes a lifting member 32, which is movably and sealingly connected to the movable cavity 31201. The rotating member 41 is rotatably connected to the high end of the lifting member 32. The oil guide channel 31103 communicates with one port of the movable cavity 31201 and corresponds to the bottom wall of the lifting member 32.

[0046] The lifting device 30 includes a pressure-drawing mechanism 33 and an oil control component 34. The pressure-drawing mechanism 33 includes a pressure-drawing body 331. The pressure-drawing body 331 is movably and sealedly inserted into the pressure-drawing cavity 31101 and partially extends from the end of the pressure-drawing cavity 31101 away from the oil guide channel 31102. The oil guide channel 31102 and the oil guide channel 31103 are connected to one port of the pressure-drawing cavity 31101, and both correspond to the end wall of the pressure-drawing body 331 located in the pressure-drawing cavity 31101. The oil control component 34 includes two oil inlet control components 341. The two oil inlet control components 341 are respectively installed in the oil inlet channel 31102 and the oil guide channel 31103. The oil inlet control component 341 installed in the oil inlet channel 31102 connects or blocks the oil chamber 3101 and the pressure chamber 31101 by opening and closing the oil inlet channel 31102. The oil inlet control component 341 installed in the oil guide channel 31103 connects or blocks the pressure chamber 31101 and the movable chamber 31201 by opening and closing the oil guide channel 31103.

[0047] Specifically, when the pressure-drawing body 331 moves away from the pressure-drawing chamber 31101 towards one end connected to the oil inlet channel 31102 within the pressure-drawing chamber 31101, the oil inlet control component 341 disposed in the oil inlet channel 31102 opens the oil inlet channel 31102, and the oil inlet control component 341 disposed in the oil guide channel 31103 closes the oil guide channel 31103. At least a portion of the hydraulic oil in the oil chamber 3101 is subjected to negative pressure and flows into the pressure-drawing chamber 31101 through the oil inlet channel 31102; when the pressure-drawing body 331 moves towards the pressure-drawing chamber 31101 within the pressure-drawing chamber 31101... When 31101 moves in the direction connected to one end of the oil guide channel 31103, the oil inlet control component 341 provided in the oil guide channel 31102 closes the oil guide channel 31102, and the oil inlet control component 341 provided in the oil guide channel 31103 opens the oil guide channel 31103. The hydraulic oil in the suction chamber 31101 is squeezed by the suction body 331 and flows into the movable chamber 31201 through the oil guide channel 31103, so as to push the lifting member 32 in the movable chamber 31201 to move upward along the movable chamber 31201, thereby driving the rotating member 41 connected to the lifting member 32 to move upward.

[0048] Preferably, each of the oil inlet control components 341 includes a plugging member 3411 and an elastic member 3412, with one end of the elastic member 3412 corresponding to one of the plugging members 3411. Taking the direction of hydraulic oil flowing from the oil inlet channel 31102 to the pressure-drawing chamber 31101 as a reference, a portion of the inner wall of the oil inlet channel 31102 expands outward to form a first abutting wall 3111. An oil inlet control component 341 is disposed on the portion of the oil inlet channel 31102 located near the pressure-drawing chamber 31101 on the side of the first abutting wall 3111. One end of the elastic member 3412 corresponding to the oil inlet control component 341, away from the corresponding plugging member 3411, is connected to the inner wall of the oil inlet channel 31102, and the plugging member 3411 corresponding to the oil inlet control component 341 is located between the first abutting wall 3111 and the corresponding elastic member 3412. Taking the direction of the hydraulic oil flowing from the pressure chamber 31101 through the oil guide channel 31103 to the movable chamber 31201 as a reference, a portion of the inner wall of the oil guide channel 31103 expands outward to form a second abutment wall 3112. Another oil inlet control component 341 is provided on the portion of the oil guide channel 31103 located on the side of the second abutment wall 3112 near the movable chamber 31201. One end of the elastic member 3412 of the oil inlet control component 341, away from the corresponding blocking member 3411, is connected to the inner wall of the oil guide channel 31103, and the blocking member 3411 of the oil inlet control component 341 is located between the second abutment wall 3112 and the corresponding elastic member 3412. When the pumping body 331 remains stationary within the pumping chamber 31101, the blocking member 3411 is abutted against the first abutting wall 3111 or the second abutting wall 3112 by the elastic force of the elastic member 3412 to close the oil inlet channel 31102 or the oil guide channel 31103.

[0049] Specifically, when the pumping body 331 moves within the pumping chamber 31101 toward one end connected to the oil inlet channel 31102 away from the pumping chamber 31101, the blocking member 3411 located in the oil inlet channel 31102 is subjected to negative pressure and overcomes the elastic force of the corresponding elastic member 3412 to be pulled apart from the first abutment wall 3111. Meanwhile, the blocking member 3411 located in the oil guide channel 31103 is subjected to both negative pressure and elastic force to remain abutting against the second abutment wall 3112. At this time, the oil inlet channel 31102 is opened while the oil guide channel 31103 remains closed. At least a portion of the hydraulic oil in the oil chamber 3101 is drawn in and flows into the pumping chamber 31101 through the oil inlet channel 31102. When the pressure chamber 31101 moves toward one end of the pressure chamber 31101 that connects to the oil guide channel 31103, the blocking member 3411 located in the oil guide channel 31103 is pushed apart from the second abutment wall 3112 by hydraulic pressure and overcomes the elastic force of the corresponding elastic member 3412. The blocking member 3411 located in the oil guide channel 31102 is kept abutting against the first abutment wall 3111 by hydraulic pressure and elastic force. At this time, the oil guide channel 31103 is opened and the oil guide channel 31102 remains closed. The hydraulic oil in the pressure chamber 31101 is squeezed and flows into the movable cavity 31201 through the oil guide channel 31103 to push the lifting member 32 inserted into the movable cavity 31201 upward.

[0050] During this process, the opening and closing of the oil inlet channel 31102 and the oil guide channel 31103, as well as the flow of hydraulic oil, are controlled by the movement of the pumping body 331, making the operation convenient.

[0051] Preferably, the elastic element 3412 is implemented as a spring.

[0052] Furthermore, the seat body 311 also has an oil return channel 31104 with both ends communicating with the oil cavity 3101 and the movable cavity 31201 respectively. One end of the oil return channel 31104 communicating with the movable cavity 31201 corresponds to the bottom wall of the lifting member 32. The oil control component 34 also includes an oil outlet control component 342, which is installed on the seat body 311 and partially placed in the oil return channel 31104. The oil outlet control component 342 connects or disconnects the oil cavity 3101 and the movable cavity 31201 by opening and closing the oil return channel 31104.

[0053] Specifically, after the pressure-drawing body 331 reciprocates within the pressure-drawing chamber 31101 to introduce at least a portion of the hydraulic oil in the oil chamber 3101 into the pressure-drawing chamber 31101 and transfer it from the pressure-drawing chamber 31101 into the movable chamber 31201, a negative pressure is formed in the oil chamber 3101. The oil outlet control component 342 connects the oil chamber 3101 and the movable chamber 31201 by opening the return oil passage 31104. The hydraulic oil in the movable chamber 31201 is subjected to negative pressure and flows into the oil chamber 3101 through the return oil passage 31104. At this time, the lifting member 32 moves downward along the pressure-drawing chamber 31101 under its own weight and negative pressure to drive the rotating member 41 to descend.

[0054] Preferably, the oil outlet control assembly 342 includes a sealing member 3421 and a driving member 3422. The driving member 3422 is threaded into the seat body 311 and partially located outside the seat body 311. The sealing member 3421 is engaged with one end of the driving member 3422 inserted into the seat body 311 and is slidably mounted on the seat body 311. Taking the direction of hydraulic oil flowing from the movable cavity 31201 through the return oil passage 31104 to the oil cavity 3101 as a reference, a portion of the inner wall of the return oil passage 31104 expands outward to form a third abutment wall 3113. The sealing member 3421 is provided on the portion of the return oil passage 31104 located on the side of the third abutment wall 3113 near the oil cavity 3101. The driving member 3422 drives the sealing member 3421 to move by rotating into or out of the seat body 311 to abut or separate from the third abutment wall 3113, thereby opening or closing the oil return passage 31104.

[0055] Specifically, when the drive member 3422 rotates to extend further into the seat body 311, the drive member 3422 drives the sealing member 3421 to move closer to the third abutment wall 3113 to abut against the third abutment wall 3113, at which time the oil return passage 31104 is closed; when the drive member 3422 rotates to move in the direction of withdrawing the seat body 311, the drive member 3422 drives the sealing member 3421 to move away from the third abutment wall 3113 to separate from the third abutment wall 3113, at which time the oil return passage 31104 is opened.

[0056] Furthermore, the pressure-drawing mechanism 33 includes a driving member 332, which includes a reset member 3321. The two ends of the reset member 3321 correspond to the pressure-drawing body 331 and the seat body 311, respectively. The reset member 3321 is capable of elastic deformation when the pressure-drawing body 331 is pressed and moves within the pressure-drawing cavity 31101 towards the side of the pressure-drawing cavity 31101 that is connected to the oil guide channel 31103. The reset member 3321 is capable of resetting the pressure-drawing body 331 when the external force is removed, so that the hydraulic oil in the oil cavity 3101 can be indirectly transferred into the movable cavity 31201.

[0057] Preferably, the reset member 3321 is implemented as a spring.

[0058] The drive member 332 includes a force-applying component 3322, which is rotatably mounted on the seat body 311 and partially corresponds to the portion of the pressure-drawing body 331 extending out of the pressure-drawing cavity 31101. The force-applying component 3322 can be force-applied to rotate the pressure-drawing body 331 to push the pressure-drawing body 331 within the pressure-drawing cavity 31101 toward the side of the pressure-drawing cavity 31101 that communicates with the oil guide passage 31103.

[0059] Preferably, the pressure chamber 31101 is vertically arranged. The force application component 3322 includes a foot pedal force application member 33221, which has a pressure application portion 332211 corresponding to the pressure body 331. One end of the foot pedal force application member 33221 is pivotally connected to the seat body 311, and the end of the foot pedal force application member 33221 away from the seat body 311 forms a stepping portion 332212. The stepping portion 332212 and the rotation axis of the foot pedal force application member 33221 are at a predetermined distance in the horizontal direction, and the pressure application portion 332211 is located between the rotation axis of the foot pedal force application member 33221 and the stepping portion 332212. When the foot pedal force-applying member 33221 is not under force, the pressure-applying part 332211 abuts against the pressure-drawing body 331, so that the foot pedal force-applying member 33221 is supported by the pressure-drawing body 331. The stepping part 332212 can be stepped on, causing the foot pedal force-applying member 33221 to rotate in such a way that the stepping part 332212 presses against the pressure-drawing body 331.

[0060] It is worth mentioning that, since the pressure-applying part 332211 is located between the rotation axis of the foot pedal force-applying component 33221 and the foot pedal part 332212, based on the lever principle, the pressure-applying body 331 can be easily moved by applying a small force to the pressure-applying part 332211, which saves time and effort and is convenient.

[0061] Furthermore, the force-applying component 3322 also includes a hand-pressing force-applying element 33222, which is rotatably mounted on the seat body 311. When the hand-pressing force-applying element 33222 is not under force, its two ends have a predetermined height difference, and the end of the hand-pressing force-applying element 33222 away from the seat body 311 is at a higher height than the foot pedal part 332212. The hand-pressing force-applying element 33222 can be pressed by hand to turn it toward the suction body 331, so as to apply pressure to the suction body 331.

[0062] Preferably, the hand-pressing force-applying member 33222 is supported by the pressure-applying part 332211 when it is not subjected to external force, and when the hand-pressing force-applying member 33222 rotates under pressure, it applies pressure to the pressure-applying part 332211 to push the suction body 331 to move within the suction cavity 31101.

[0063] In this way, by applying pressure to either the foot pedal force application component 33221 or the hand pressure force application component 33222 to move the pump body 331, the usage methods are enriched and the flexibility of use is increased.

[0064] Furthermore, the mounting frame 10 includes a frame body 11 and a plurality of rollers 12. The slide groove 101 is formed on the frame body 11. The plurality of rollers 12 are spaced apart and rotatably mounted on the frame body 11 so that the frame body 11 can be moved on the ground by the rollers 12 rolling, thereby increasing the convenience of overall transfer.

The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
