Description

Technical Field

[0001] The utility model relates to a lifting technology and belongs to the field of logistics transportation, in particular to a track-changing type lifting device. Background Art

[0002] An elevator is a device used to transport materials vertically or obliquely. It mainly drives the transmission device through a motor to make the lifting bucket or lifting belt circulate along the guide device, thereby transporting the materials vertically or obliquely to the destination. Due to its simple structure and easy operation, it is widely used in cement, fertilizer, mining, metallurgy, building materials and other industries to transport bulk materials, powdery materials or block materials.

[0003] To ensure the stability of the elevator, the elevator base is often fixed, that is, it is fixed to the corresponding foundation by means of anchor bolts, etc. However, during the transportation of turnover boxes, the conveyor lines are usually double or even multiple, and the conveyor lines need to change tracks at different heights to meet the transportation of turnover boxes. Traditional elevators are not suitable for track changing and lifting of multiple conveyor lines, or multiple elevators are required to be matched at the corresponding conveyor lines, resulting in a waste of resources; in addition, when the elevator is lifting, because the lifting conveyor line is too heavy or the elevator has been working for too long, it will continue to cause a large load on the lifting motor, causing the lifting motor to overheat and affect its service life. Summary of the invention

[0004] The utility model aims to provide a track-changing lifting device with a simple structure, which can realize track-changing lifting of multiple conveyor lines, meet the needs of staggered lifting and docking of conveyor lines at different heights, and effectively reduce the driving force used for lifting, avoiding excessive driving force load caused by excessive weight of the conveyor line.

[0005] In order to achieve the above purpose, the track-changing lifting equipment includes:

[0006] The moving component is installed on the base plate, and includes a moving motor located on the base plate, a driving shaft rotating on the base plate, and a supporting slider moving on the first slide rail;

[0007] The output end of the mobile motor is connected to one end of the driving shaft;

[0008] The supporting main frame is fixed on the supporting sliding block, and the ear seat at the lower end is threadedly connected with the driving shaft;

[0012] Furthermore, the driving component comprises:

[0013] Lifting motor;

[0014] A first gear is rotatably mounted on the upper end of the supporting main frame via a supporting shaft;

[0015] The second gear is located below the first gear, secured at the output end of the lifting motor and at the bottom end of the supporting main frame;

[0016] The first chain is wound around the outside of the first gear, and the second chain is wound around the outside of the second gear.

[0017] Furthermore, the counterweight assembly includes a plurality of counterweight blocks stacked one above the other, and a fixing rod passing through the corresponding counterweight blocks;

[0018] Nuts are installed at the upper and lower ends of the fixing rod to fix the multiple counterweights.

[0019] Further, the counterweight assembly is a closed counterweight box;

[0020] The counterweight box body is provided with a material inlet at the upper end, a material outlet at the lower end, and a fluid for counterweight is arranged inside.

[0021] Furthermore, the counterweight assembly is laterally provided with a plurality of rollers arranged up and down;

[0022] An annular groove is arranged on the circumference of the roller, and a limit plate arranged vertically on the supporting main frame is embedded in the annular groove.

[0023] Furthermore, the support plate component includes:

[0024] A support frame is slidably arranged on the support main frame;

[0025] The support plate is fixed on the support frame and has an L-shaped structure with one end facing horizontally toward the conveyor line.

[0026] Furthermore, the support plate component is mounted on the supporting main frame via a second slide rail;

[0027] An elastic limit block or a position sensor is provided at the upper end of the second slide rail;

[0028] After receiving the signal from the position sensor, the controller controls the action of the lifting motor.

[0029] Compared with the prior art, the track-changing lifting device is started by the moving motor in the moving component to drive the driving shaft to rotate, so that the supporting main frame moves longitudinally on the supporting slider, and matches with the lifting component that drives the pallet component to move up and down, so as to realize the track-changing lifting of multiple conveyor lines and meet the staggered lifting and docking of conveyor lines at different heights; in addition, a counterweight component is provided in the lifting component, and the counterweight component forms a closed loop with the first chain, the second chain, and the supporting pallet, so that during the lifting process, the driving force used to drive the first chain or the second chain to move can be effectively reduced, so as to avoid excessive driving force load caused by excessive weight of the conveyor line;

[0030] Since the counterweight assembly is a closed counterweight box with a counterweight fluid inside, the counterweight material is injected from the inlet and can be discharged from the outlet, so the counterweight can be reasonably carried out according to the weight of the conveyor line and the weight of the conveying turnover box; in addition, the counterweight assembly is provided with a plurality of rollers arranged up and down on the side, and matched with the limit plates arranged vertically on the supporting main frame. When the counterweight assembly moves up and down, the contact between the rollers and the limit plates is used to achieve the stability of the movement of the counterweight assembly to prevent it from swinging.

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figures 1 to 5 As shown, the track-changing lifting equipment comprises:

[0044] The moving component 30 is installed on the base plate 20, and includes a moving motor 32 located on the bottom plate 31, a driving shaft 33 rotating on the bottom plate 31, and a supporting slider 35 moving on a first slide rail 34;

[0045] The output end of the moving motor 32 is connected to one end of the driving shaft 33;

[0046] The support main frame 50 is fixed on the support slider 35, and the ear seat at the lower end is threadedly connected with the drive shaft 33;

[0047] The lifting component 60 is installed on the supporting main frame 50, and includes a first chain 63, a second chain 64, a counterweight assembly 65 and a support plate component 40 forming a closed loop structure;

[0048] One end of the first chain 63 is connected to the upper end of the pallet component 40, and the other end is connected to the upper end of the counterweight assembly 65 after being wound upward; one end of the second chain 64 is connected to the lower end of the pallet component 40, and the other end is connected to the lower end of the counterweight assembly 65 after being wound downward; the first chain 63 or the second chain 64 is connected to the driving assembly, so that the pallet component 40 at the conveyor line 10 moves up and down;

[0049] Specifically, the moving component 30 is used to drive the lifting component 60 to move longitudinally. As shown in the figure, the plurality of conveying lines 10 are arranged longitudinally and convey transversely; the base plate 20 is fixed to the foundation by means of anchor bolts, etc., and the bottom plate 31 is installed on the base plate 20 by means of shock absorbing components, support seat components, etc.;

[0050] The driving shaft 33 is provided with external threads, and both ends are rotatably mounted on the fixing seat 36 through bearings, and the fixing seat 36 is fixed on the bottom plate 31; there can be multiple supporting sliders 35, which slide on the first slide rail 34;

[0051] The supporting main frame 50 may be formed by welding rectangular tubes, panels, etc. or by bolts to form a frame structure for overall support;

[0052] The lifting component 60 is installed on the supporting main frame 50, and the first chain 63 and the second chain 64 can adopt the same specifications; the position of the counterweight component 65 is opposite to the position of the supporting plate component 40, that is, when the first chain 63 and the second chain 64 of the closed-loop structure are moving, the moving direction of the counterweight component 65 is opposite to that of the supporting plate component 40;

[0053] The support plate component 40 is used to connect with the conveyor line 10;

[0054] The track-changing lifting equipment is located on one side of multiple conveyor lines 10, and multiple conveyor lines 10 can normally convey turnover boxes. The first roller conveyor line 10 and the second roller conveyor line 10 arranged side by side in the longitudinal direction are used as an example for explanation;

[0055] The support plate component 40 is located below the first roller conveyor line 10. The driving assembly is actuated to move the first chain 63 or the second chain 64. The support plate component 40 receives the first roller conveyor line 10 for lifting. Under the action of the counterweight assembly 65, the driving assembly drives the first chain 63 or the second chain 64 to move with a relatively small driving force, thereby preventing the first roller conveyor line 10 from being overweight and causing an excessive driving force load.

[0056] When the first roller conveyor line 10 is lifted, the moving component 30 can be moved, that is, the moving motor 32 is started, driving the driving shaft 33 to rotate, so that the supporting main frame 50 moves longitudinally on the supporting slider 35, driving the first roller conveyor line 10 to change tracks at different heights, such as moving to the top of the second roller conveyor line 10;

[0057] When the track change of the first roller conveyor line 10 is completed, the lifting component 60 and the moving component 30 act accordingly, so that the support component 40 moves to the bottom of the second roller conveyor line 10 and receives it, and the lifting component 60 and the moving component 30 then act to move the second roller conveyor line 10 to a different height for track change, such as moving it to the original position of the first roller conveyor line 10;

[0058] The track-changing lifting device drives the lifting component 60 to move longitudinally through the moving component 30, and the lifting component 60 drives the support component 40 to move up and down, thereby realizing the track-changing lifting of multiple conveyor lines 10 and meeting the staggered lifting and docking of conveyor lines 10 at different heights; in addition, a counterweight assembly 65 is provided in the lifting component 60, and the counterweight assembly 65 forms a closed loop with the first chain 63, the second chain 64, and the support component 40. During the lifting process, the driving force used to drive the first chain 63 or the second chain 64 to move can be effectively reduced, thereby avoiding excessive driving force load caused by excessive weight of the conveyor line 10.

[0059] like Figure 5 As shown, further, the driving component includes:

[0060] Lifting motor 61;

[0061] The first gear 62 is rotatably mounted on the upper end of the supporting main frame 50 via a supporting shaft 69;

[0062] The second gear 67 is located below the first gear 62, secured at the output end of the lifting motor 61 and at the bottom end of the supporting main frame 50;

[0063] The first chain 63 is wound around the outside of the first gear 62, and the second chain 64 is wound around the outside of the second gear 67;

[0064] Specifically, the lifting motor 61 may be a servo motor and connected to the controller, and to ensure the stability of lifting, the lifting motor 61 is a double output shaft structure, and each end is connected to the first gear 62;

[0065] The first gear 62 and the second gear 67 may have the same specifications and be located in the same vertical plane;

[0066] When the lifting motor 61 is started, the first gear 62 is controlled to rotate, the first chain 63 matches the first gear 62, and the second chain 64 matches the second gear 67. After the first gear 62 rotates, it will drive the first chain 63, the support plate component 40, the second chain 64, and the counterweight assembly 65 to move, so that the support plate component 40 moves up and down.

[0067] As a first embodiment of the counterweight assembly 65, the counterweight assembly 65 includes a plurality of counterweight blocks stacked one above the other, and a fixing rod 66 passing through the corresponding counterweight blocks;

[0068] Nuts are installed at the upper and lower ends of the fixing rod 66 to fix the multiple counterweights;

[0069] That is, in this way, multiple counterweights are inserted and fixed through the fixing rod 66, and the number of counterweights can be determined according to the overall weight of the conveyor line 10;

[0070] As a second embodiment of the counterweight assembly 65, the counterweight assembly is a closed counterweight box;

[0071] The counterweight box body is provided with a material inlet at the upper end and a material outlet at the lower end;

[0072] Specifically, the counterweight box can be filled with fluid counterweight materials such as sand and oil. The counterweight materials are injected from the inlet and discharged from the outlet. The counterweight can be reasonably performed according to the weight of the conveying line 10 and the weight of the conveying turnover box.

[0073] Alternatively, when oil is used as a counterweight in the counterweight box, the input pipe is connected to the feed inlet and the output end is connected to the discharge port. The controller controls the input and output amounts of the oil to achieve real-time adjustment of the counterweight assembly 65.

[0074] like Figure 4 As shown, further, the counterweight assembly 65 is laterally provided with a plurality of rollers 68 arranged up and down;

[0075] An annular groove is provided on the periphery of the roller 68, and a limit plate arranged vertically to support the main frame 50 is embedded in the annular groove;

[0076] Specifically, when the counterweight assembly 65 moves up and down, the contact between the roller 68 and the limit plate is used to achieve stability in the movement of the counterweight assembly 65 and prevent it from swinging.

[0077] like Figure 2 , Figure 4 As shown, in some embodiments, the support plate component 40 includes:

[0078] A support frame 42 is slidably disposed on the support main frame 50;

[0079] The support plate 41 is fixed on the support frame 42 and has an L-shaped structure, with one end facing the conveyor line 10 horizontally;

[0080] Specifically, the support frame 42 can be formed by welding rectangular tubes, and there are multiple support pallets 41 arranged side by side. Each support pallet 41 is an L-shaped structure, with one part installed on the support frame 42 and the other part arranged horizontally to support the conveyor line 10.

[0081] In some embodiments, the support plate component 40 is mounted on the supporting main frame 50 via a second slide rail;

[0082] An elastic limit block 43 or a position sensor is provided at the upper end of the second slide rail;

[0083] After receiving the signal from the position sensor, the controller controls the action of the lifting motor 61;

[0084] Specifically, when the support plate component 40 moves upward to a certain position, the limit block 43 limits the moving height, or the position sensor senses the moving position of the support plate component 40. When it is within the set range, the controller receives the signal and controls the lifting motor 61 to move;

[0085] As explained, the actions of the lifting motor 61 are starting, stopping, and forward and reverse rotation.

[0086] When the track-changing lifting device is used, the support plate 41 is located below one of the conveyor lines 10, and the lifting motor 61 is started. The first chain 63 and the second chain 64 are rotated through the first gear 62 and the second gear 67, driving the support plate component 40 to move up and down. Under the action of the counterweight assembly 65, the load of the lifting motor 61 is small, so as to avoid the overheating of the lifting motor 61 caused by the overweight of the first roller conveyor line 10;

[0087] When the conveyor line 10 is lifted, the moving motor 32 is started, driving the driving shaft 33 to rotate, so that the supporting main frame 50 moves longitudinally on the supporting slider 35, driving the conveyor line 10 to change tracks at different heights;

[0088] When the track change of this conveyor line 10 is completed, the lifting component 60 and the moving component 30 act accordingly, so that the pallet component 40 moves to the bottom of the second roller conveyor line 10 and takes over, and the lifting component 60 and the moving component 30 then act to move the two conveyor lines 10 to different heights for track change.

[0089] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
