DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The following is combined with Figure 1-Figure 6 The specific implementation modes of the present invention are described in further detail.

[0026] Depend on Figure 1-Figure 6 It is given that, in order to increase the function of detecting the inclination of the conveying platform 1, the present invention comprises a liftable conveying platform 1 for conveying materials; A lower plane 2 and an upper frame 3 for loading and unloading materials, with inclined surfaces 4 being provided on both the front and rear sides of the lower plane 2; A liftable power rod 5, the lower side of which is connected to the conveying platform 1; A hydraulic power assembly 6, used to provide power for the power rod 5 to move up and down; Two left-right symmetrical support frames 7 are respectively located on the left and right sides of the conveying platform 1. The upper frame 3 and the lower platform are fixedly connected to the support frames 7. Each support frame 7 includes two front-to-back symmetrical support columns 8. A plurality of fixing rods 9 are arranged between the two support columns 8. The conveying platform 1 and the power rod 5 are connected to each support column 8. The movable pulley assembly 10 is used to connect the power rod 5 and the conveying platform 1; At least two tilt detection mechanisms 11, connected between the conveying platform 1 and the support frame 7, for detecting the tilt of the conveying platform 1; It should be noted that the present invention is used for lifting and transporting materials as a whole, and can transport materials on the lower plane 2 to a higher place through the conveying platform 1, and the upper frame 3 and the unloading platform at the higher place are at the same horizontal plane; through the movable pulley assembly 10, the lifting stroke of the conveying platform 1 can be increased; When in use, the conveying platform 1 can be used to lift and transport materials. The inclined surface 4 can facilitate the transportation of materials to the inside of the conveying platform 1. After that, the hydraulic power assembly 6 can be used to drive the power rod 5 to lift and lower. The power rod 5 drives the conveying platform 1 to lift and lower through the movable pulley assembly 10, thereby lifting and transporting the materials. During the lifting and lowering of the conveying platform 1, the support frame 7 can limit the conveying platform 1 to make its lifting and lowering smoother. When the conveying platform 1 moves downward along the support frame 7, a jam may occur between the conveying platform 1 and the support frame 7, which may easily cause a safety hazard that the goods tilt together with the conveying platform 1. The tilt detection mechanism 11 can detect the angle of the conveying platform 1 relative to the support frame 7. When a jam occurs, the conveying platform 1 will tilt. After the tilt detection mechanism 11 detects and alarms, the lifting and lowering action of the conveying platform 1 can be stopped in time, which is convenient for the staff to further handle. Since the jam may occur at any position where the conveying platform 1 contacts the support frame 7, in this embodiment, four tilt detection mechanisms 11 are provided, which are respectively located on the front and rear sides of the two support frames 7, and the four corners of the conveying platform 1 can be detected.

[0027] Furthermore, in order to increase the safety of material lifting, a guardrail 12 is fixedly connected to the left and right sides of the conveying platform 1, and the guardrail 12 is used to protect the left and right sides of the conveying platform 1. Furthermore, protective doors are provided on the front and rear sides of the conveying platform 1, and each protective door is rotatably connected to the corresponding guardrail 12. A reinforcing rod 13 is fixedly connected to the side of each guardrail 12 away from the conveying platform 1; When in use, the movable pulley assembly 10 and the tilt detection mechanism 11 are both connected to the reinforcement rod 13 on the conveying platform 1 .

[0028] Further, by Figure 1-Figure 6 It is given that, in order to reduce the probability of jamming when the conveying platform 1 is lifted or lowered, a first moving plate 14 is fixedly connected to the front and rear sides of each reinforcement rod 13, a limiting groove 15 is provided on each support column 8, and a plurality of transverse limiting wheels 16 are rotatably connected to the side of each first moving plate 14 close to the support column 8, and each transverse limiting wheel 16 is in rolling contact with the limiting groove 15, and a plurality of longitudinal limiting wheels 17 are rotatably connected to the middle part of each first moving plate 14, and each longitudinal limiting wheel 17 is in rolling contact with the side of the support column 8 close to the first moving plate 14; It should be noted that the transverse limiting wheel 16 is placed in the limiting groove 15, which is used to limit the freedom of the conveying platform 1 in the left and right directions. The longitudinal limiting wheel 17 is in contact with two close surfaces of two support columns 8 in the same support frame 7, and under the action of the first moving plate 14 and the reinforcement rod 13, the freedom of the conveying platform 1 in the front and rear directions can be limited.

[0029] Furthermore, in order to increase the service life of the device, the hydraulic power assembly 6 includes two left-right symmetrical hydraulic rods 18, and the output end of each hydraulic rod 18 is fixedly connected to a connecting block 19, and the upper side of each connecting block 19 is rotatably connected to the power rod 5; It should be noted that the hydraulic rod 18 is a prior art and will not be described in detail here. The hydraulic rod 18 can be conveniently connected to the power rod 5 through the connecting block 19, and the lower side of the hydraulic rod 18 is fixedly connected to the lower side plane 2.

[0030] Further, by Figure 1-Figure 6 It is given that, in order to increase the lifting stroke of the conveying platform 1, the movable pulley assembly 10 includes a sprocket 20 rotatably connected to the power rod 5, and a chain 21 is matched on the outer side of the sprocket 20, and the two ends of the chain 21 are fixedly connected to the support frame 7 and the conveying platform 1 respectively; When in use, during the process of raising and lowering the power rod 5, the sprocket 20 will be driven to rise and fall. Since the two ends of the chain 21 are respectively fixedly connected to the support frame 7 and the conveying platform 1, the sprocket 20 can be regarded as a movable pulley in a conventional pulley group, that is, when the power rod 5 is lifted by one unit distance, the chain 21 will drive the conveying platform 1 to rise by two unit distances, thereby increasing the lifting distance of the conveying platform 1 when the stroke of the hydraulic rod 18 is fixed.

[0031] Further, by Figure 1-Figure 6 It is given that in order to accurately detect the jamming phenomenon of the conveying platform 1, the tilt detection mechanism 11 includes a movable pulley 22 rotatably connected to the power rod 5, the outer side of the movable pulley 22 is matched with a connecting rope 23, a detection box 24 is fixedly connected to the middle of the support frame 7, and a detection piece 25 that can slide up and down is provided inside the detection box 24. The detection piece 25 is in a convex shape, one end of the connecting rope 23 is connected to the detection piece 25, and the other end of the connecting rope 23 is connected to the support frame 7. A tension spring 26 is fixedly connected to the lower side of the detection piece 25, and a detection rod 27 is slidably connected to the middle of the detection box 24. The side of the detection rod 27 close to the detection piece 25 abuts against the detection piece 25, and the detection piece 25 moves up and down to form a structure in which the detection rod 27 moves left and right; Further, by Figure 1-Figure 6In order to increase the function of timely alarm, a first connecting plate 28 is fixedly connected to the middle of the detection rod 27, and a second connecting plate 29 fixedly connected to the detection box 24 is provided on both the upper and lower sides of the first connecting plate 28. The second connecting plate 29 is L-shaped, and a touch switch 30 is provided on one side of the second connecting plate 29 close to the first connecting plate 28. A signal sending module 31 is provided inside the detection box 24, and each touch switch 30 is electrically connected to the signal sending module 31; It should be noted that the connection structure between the movable pulley 22 and the connecting rope 23 is similar to the connection structure between the sprocket 20 and the chain 21. During the lifting and lowering process of the conveying platform 1, the chain 21 is used to provide the lifting and lowering pulling force of the conveying platform 1. During the normal operation of the device, the detection rod 27 abuts against the middle part of the first connecting plate 28. A spring is provided on the side of each detection rod 27 away from the first connecting plate 28, so that the detection rod 27 has a tendency to move close to the first connecting plate 28. During the lifting and lowering process of the first connecting plate 28, the detection rod 27 will move to the right under the action of the spring; a signal receiving module is provided inside the hydraulic rod 18, and the signal sending module 31 is connected to the hydraulic rod 18 through Bluetooth or 4G signals; the connecting rope 23 is a steel wire rope; During use, when a jam occurs (occurs during descent), the conveying platform 1 moves downward under the action of gravity and is prevented by the friction force caused by the jam, while the power column still descends under the action of the hydraulic cylinder. At this time, the chain 21 and the connecting rope 23 at the corresponding position will become loose, and the detection piece 25 will move downward under the action of the tension spring 26, thereby causing the detection rod 27 to move to the right relative to the detection box 24. The detection rod 27 drives the first connecting plate 28 to contact the touch switch 30, and stops the descending action of the hydraulic rod 18 through the signal sending module 31.

[0032] Further, by Figure 1-Figure 6 It is shown that a sliding sheet 32 ​​is fixedly connected to one side of the detection sheet 25 close to the detection box 24, and a detection guide rail 33 is fixedly connected inside the detection box 24, and the detection guide rail 33 is slidably connected to the sliding sheet 32; When in use, the cooperation between the detection guide rail 33 and the sliding sheet 32 ​​can make the lifting and lowering of the detection sheet 25 smoother.

[0033] Further, by Figure 1-Figure 6It is given that, in order to facilitate the debugging of the entire device, a first adjusting block 34 is fixedly connected to the upper part of the detection piece 25, a first threaded rod 35 is rotatably connected to the middle part of the first adjusting block 34, a first sliding block 36 is threadedly connected to the middle part of the first threaded rod 35, a first fixture 37 is fixedly connected to the side of the first sliding block 36, the first fixture 37 is connected to one end of the connecting rope 23, the other end of the connecting rope 23 is connected to a second fixture 38, a first hook 39 is fixedly connected to the lower end of the second fixture 38, a second hook 40 is provided on the lower side of the first hook 39, an adjusting rod 41 is fixedly connected to the lower side of the second hook 40, and an adjusting sleeve 42 is rotatably connected to the position corresponding to each adjusting rod 41 on the conveying platform 1, and each adjusting rod 41 is threadedly connected to the corresponding adjusting sleeve 42; During use, since the tension spring 26 is in a force storage state when the device is running, when the connecting rope 23 and the detection piece 25 are installed, the two ends of the connecting rope 23 can be connected respectively by the first fixer 37 and the second fixer 38, and the first threaded rod 35 can be rotated to make the first sliding block 36 drive the first fixer 37 to rise and fall relative to the detection piece 25. At this time, the detection piece 25 will rise relative to the detection box 24, so that the tension spring 26 can store force, and the tilt detection mechanism 11 enters the working state. In addition, during the use of the device, the adjusting sleeve 42 can be rotated to make the adjusting sleeve 42 drive the adjusting rod 41 to move downward, and then one end of the connecting rope 23 is pulled downward by the second hook 40 and the first hook 39. The position of the detection piece 25 relative to the detection rod 27 can also be adjusted to facilitate the operation of the staff.

[0034] Further, by Figure 1-Figure 6 In order to facilitate the operation of the staff, it also includes a control panel 43 fixedly connected to the support frame 7, and the control panel 43 is electrically connected to the hydraulic power assembly 6 and the tilt detection mechanism 11; It should be noted that the control panel 43 is a prior art, and at least one alarm light (electrically connected to the touch switch 30, used for alarm when tilt jamming occurs) and two operation buttons (electrically connected to the hydraulic rod 18 and the touch switch 30, used to control the lifting and lowering of the conveying platform 1) are arranged on its upper side. In addition, the above-mentioned electronic components (including the control panel 43, the hydraulic rod 18, and the signal sending module 31) are all controlled by the controller. This application does not make any improvements to the circuit part. The control method of the controller is very mature in the prior art and will not be described in this article.

[0035] When the present invention is used, the materials can be lifted and transported through the conveying platform 1 first, and the materials can be conveniently transported to the inside of the conveying platform 1 through the inclined surface 4. Then, the power rod 5 can be driven to lift and lower through the hydraulic power assembly 6, and the power rod 5 drives the conveying platform 1 to lift and lower through the movable pulley assembly 10, thereby lifting and transporting the materials. During the lifting and lowering of the conveying platform 1, the support frame 7 can limit the conveying platform 1 to make its lifting and lowering smoother. When the conveying platform 1 moves downward along the support frame 7, a jamming phenomenon may occur between the conveying platform 1 and the support frame 7, which may easily cause a safety hazard that the goods tilt together with the conveying platform 1. The angle of the conveying platform 1 relative to the support frame 7 can be detected by the inclination detection mechanism 11. When a jamming phenomenon occurs, the conveying platform 1 will tilt, and then after detection and alarm by the inclination detection mechanism 11, the lifting and lowering action of the conveying platform 1 can be stopped in time, which is convenient for the staff to carry out further processing. Since the jamming phenomenon may occur at any position where the conveying platform 1 contacts the support frame 7, the inclination detection mechanism 11 is respectively located on the front and rear sides of the two support frames 7, and the four corners of the conveying platform 1 can be detected.

[0036] The present invention has a novel structure, ingenious conception, and simple and convenient operation. Through this design, the function of detecting the inclination of the conveying platform 1 is effectively added, making the lifting and transportation of materials safer, reducing the probability of jamming of the conveying platform 1 during lifting, increasing the service life of the device, increasing the lifting stroke of the conveying platform 1, being able to accurately detect the jamming phenomenon of the conveying platform 1, adding the functions of alarm and automatic stop, and facilitating the debugging of the detection sensitivity of the device.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
