Description

Technical Field

[0001] This utility model relates to a feed lifting device. Background Technology

[0002] Feed production requires mixing different combinations of materials in a mixing tank, and then outputting the mixture to the next-level packaging facility for weighing and packaging. The mixing tanks used for large-scale feed production are quite large. They are usually built in the factory with a steel frame structure with the top of the mixing tank exposed. Materials are carried up the stairs to the overhead layer for feeding. This method is labor-intensive and has low mobility. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a feed lifting device. The device loads materials located on the ground through a loading mechanism, and then lifts the loading mechanism to transport the materials to the elevated floor, reducing manual handling by climbing stairs and improving production efficiency. At the same time, the anti-fall mechanism can prevent the loading mechanism from suddenly falling due to the failure of the drive device, which is a safety problem. The protective fence mechanism surrounds the placement point of the loading mechanism on the ground and the lifting clearance port, preventing personnel from accidentally falling from the lifting clearance port or standing under the falling loading mechanism due to lack of attention, thus facilitating safe production.

[0004] This utility model is implemented using the following solution: a feed lifting device includes a high-level frame erected on the ground, and sliding columns symmetrically arranged on the ground. The sliding columns penetrate the high-level frame and extend upward. A loading mechanism is slidably connected between the two sliding columns. A lifting clearance opening is provided on the high-level frame corresponding to the loading mechanism. An anti-fall mechanism is provided on the sliding columns at the position where the loading mechanism stops on the high-level frame. Protective fence mechanisms are installed on both the lifting clearance opening and the ground corresponding to the loading mechanism.

[0005] Furthermore, the loading mechanism includes a loading base plate, on which vertical support columns are symmetrically installed in the middle of the left and right sides. Several inclined reinforcing support rods are welded between the support columns and the same side edge of the loading base plate. A lifting crossbar is placed horizontally between the tops of two support columns. At least one slider is provided at intervals from top to bottom on the side of the support column. A vertical slide rail is provided on the side of the sliding column corresponding to the slider.

[0006] Furthermore, the tops of the two sliding columns are connected by a supporting beam, and a winding bracket is installed on the ground next to one of the sliding columns. A winding roller driven by a motor is rotatably connected to the winding bracket, and a lifting rope for driving the lifting and lowering of the loading mechanism is wound on the winding roller.

[0007] Furthermore, several guide wheels are installed at intervals along the length direction on the sliding column and support beam near the winding bracket. A fixing hook for attaching the end of the lifting rope is provided on the top of the sliding column away from the winding bracket. The end of the lifting rope is guided and attached to the fixing hook by the guide wheels. A vertical through hole is opened in the middle of the support beam. A section of the lifting rope located on the support beam extends downward through the through hole to form a U-shaped hook placement rope. A hook assembly is slidably attached to the hook placement rope.

[0008] Furthermore, the hook assembly includes two symmetrically arranged mounting plates, with a grooved wheel rotatably connected between the mounting plates. The grooved wheel is hung on the hook placement rope. The two mounting plates are connected by several connecting rods. A hook is provided between the lower parts of the two mounting plates. A hanging groove is provided on the support beam corresponding to the hook.

[0009] Furthermore, the anti-fall-off mechanism includes an anti-fall-off fixing bracket, on which at least one vertical sleeve is installed. A rotating rod is rotatably connected inside the vertical sleeve. A limit pin is horizontally placed on the rotating rod. Guide holes are provided at both ends of the vertical sleeve corresponding to the limit pin. The two ends of the limit pin slide into the corresponding guide holes. A limit plate is installed on the lower end of the rotating rod.

[0010] Furthermore, the protective fence mechanism includes vertical fence posts located at the four corners, and the front and rear vertical fence posts on the left and right sides, as well as the left and right vertical fence posts on the rear side, are connected by several horizontal fence posts spaced from top to bottom, and a front fence is engaged between the two vertical fence posts on the front side.

[0011] Furthermore, the front fence includes horizontal bars arranged parallel to each other, and the horizontal bars are connected by vertical bars arranged at intervals. Vertical inserts are provided at both ends of the horizontal bars, and plug sleeves are provided on the two vertical fence bars on the front side corresponding to the vertical inserts.

[0012] Furthermore, a fixed guardrail is installed between the rear sides of the two support columns on the loading base plate, and a hinged rotating guardrail is connected between the front sides of the two support columns.

[0013] Furthermore, the flip-up movable guardrail includes L-shaped flip bars arranged symmetrically on the left and right sides, with the horizontal part of the L-shaped flip bar on top and the vertical part on the bottom. The horizontal end of the L-shaped flip bar is hinged to a support column on the same side, and several horizontal connecting rods are arranged between the vertical parts of the two L-shaped flip bars from top to bottom.

[0014] Compared with the prior art, the present invention has the following advantages: it is reasonably designed, loads materials located on the ground through a loading mechanism, and then lifts and lowers the loading mechanism to transport the materials to the elevated floor, reducing manual handling by climbing stairs and improving production efficiency. At the same time, the anti-fall mechanism can avoid the safety problem of the loading mechanism suddenly falling due to the failure of the drive device. The protective fence mechanism surrounds the placement point of the loading mechanism on the ground and the lifting clearance port, preventing personnel from accidentally falling from the lifting clearance port or standing under the falling loading mechanism due to lack of attention, thus facilitating safe production.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] like Figure 1-10As shown, a feed lifting device includes a raised platform 1 erected on the ground, and sliding columns 2 symmetrically arranged on the ground. The sliding columns penetrate the raised platform and extend upwards. A loading mechanism 3 is slidably connected between the two sliding columns. A lifting clearance opening 4 is provided on the raised platform corresponding to the loading mechanism. An anti-fall mechanism 5 is provided on the sliding columns corresponding to the position where the loading mechanism stops on the raised platform. Protective fence mechanisms 6 are installed on both the lifting clearance opening and the ground corresponding to the loading mechanism. In use, the loading mechanism loads materials located on the ground, and then the loading mechanism is lifted to transport the materials to the raised platform, reducing manual handling by climbing stairs and improving production efficiency. At the same time, the anti-fall mechanism can prevent the loading mechanism from suddenly falling due to the failure of the drive device. The protective fence mechanism surrounds the placement point of the loading mechanism on the ground and the lifting clearance opening to prevent personnel from accidentally falling through the lifting clearance opening or standing under the falling loading mechanism due to lack of attention, thus facilitating safe production.

[0030] In this embodiment, to achieve the sliding of the loading mechanism, the loading mechanism includes a loading base plate 7. Vertical support columns 8 are symmetrically welded to the middle of the left and right sides of the loading base plate. Several inclined reinforcing support rods 9 are also welded between the support columns and the same side edge of the loading base plate. That is, several inclined reinforcing support rods are provided on the front and rear sides of the support columns. The reinforcing support rods reinforce the connection between the support columns and the loading base plate, and also enclose the left and right sides of the loading base plate to prevent the material from falling from the left and right sides during the lifting process due to the material not being placed securely. A lifting crossbar 10 is placed horizontally between the tops of the two support columns. At least one slider 11 is provided at intervals from top to bottom on the side of the support column. A vertical slide rail 12 is provided on the side of the sliding column corresponding to the slider. The lifting is achieved by the cooperation of the slider and the slide rail.

[0031] In this embodiment, to drive the sliding of the loading mechanism, the tops of the two sliding columns are connected by a supporting beam 13. A winding bracket 14 is installed on the ground next to one of the sliding columns. A winding roller 15 driven by a motor is rotatably connected to the winding bracket. A lifting rope 16 for driving the lifting of the loading mechanism is wound on the winding roller. The lifting rope can be a steel cable. The motor drives the winding roller to rotate, thereby driving the winding or unwinding of the lifting rope. Several guide wheels 17 are rotatably connected at intervals along the length of the sliding column and the length of the supporting beam near the winding bracket. Guide wheel mounting frames are provided on the sliding column and the supporting beam corresponding to the guide wheels. The guide wheels are rotatably connected to the guide wheel mounting frames via a rotating shaft. A fixed hook 18 for attaching the end of the lifting rope is provided on the top of the sliding column of the rewinding bracket. The end of the lifting rope is guided and attached to the fixed hook by a guide wheel. That is, the end of the lifting rope is guided upward by the guide wheel at the bottom of the side of the sliding column, and then guided to the fixed hook by the guide wheel on the support beam. A vertical through hole 19 is opened in the middle of the support beam. A section of the lifting rope located on the support beam extends downward through the through hole to form a U-shaped hook placement rope 20. A hook assembly 21 is slidably connected to the U-shaped area of ​​the hook placement rope. The support beam is hung on the hook assembly. By winding or unwinding the lifting rope, the length of the U-shaped hook placement rope decreases or increases, thereby realizing the lifting and lowering of the hook assembly, and thus realizing the lifting and lowering of the loading mechanism.

[0032] In this embodiment, in order to enable the support beam to be hung on the hook assembly, the hook assembly has the following structure: the hook assembly includes two symmetrically arranged mounting plates 22, which are connected by welding several connecting rods 23. Alternatively, they can be connected by existing methods such as bolts. A grooved wheel 24 is rotatably connected between the upper parts of the two mounting plates via a rotating shaft. The grooved wheel is hung on the U-shaped area of ​​the hook placement rope. An existing hook 25 is provided between the lower parts of the two mounting plates. A hanging groove 26 is provided on the middle part of the support beam corresponding to the hook. The hanging groove of the support beam is hung on the hook, so that the support beam can be hung on the hook assembly.

[0033] In this embodiment, to improve the safety of the equipment, the anti-fall mechanism includes an anti-fall fixing bracket 27, on which at least one vertical sleeve 28 is installed. There can be two concentric vertical sleeves. A rotating rod 29 is rotatably connected inside the vertical sleeve. Alternatively, one rotating rod can be fitted inside multiple vertical sleeves. A limiting pin 30 is horizontally placed on the rotating rod. Guide holes 31 are provided on the outer wall of the vertical sleeve corresponding to the two ends of the limiting pin. The two ends of the limiting pin slide into the corresponding guide holes. A limiting plate 32 is installed on the lower end of the rotating rod. The two extreme positions of the limiting pin rotation correspond to the limiting plate being fully rotated under the load base plate and the limiting plate being completely separated from the load base plate. At the same time, the anti-fall mechanism can prevent the load mechanism from suddenly falling due to the failure of the drive device.

[0034] In this embodiment, to prevent personnel from accidentally falling through the lifting clearance opening or from unknowingly standing under the falling loading mechanism, and to facilitate safe production, the protective fence mechanism includes vertical fence posts 33 at the four corners. The vertical fence posts of the protective fence mechanism located at the lifting clearance opening are welded to the elevated floor, and the vertical fence posts of the protective fence mechanism located on the ground are fixed to the ground. The adjacent vertical fence posts on the left and right sides, as well as the adjacent vertical fence posts on the rear side, are connected by several horizontal fence posts 35 welded at intervals from top to bottom, achieving enclosure in three directions. The two adjacent vertical fence posts on the front side are connected by several horizontal fence posts 35. A front fence 36 is snapped between the vertical fence bars. When materials need to be placed or removed on the loading mechanism, the protective fence mechanism can be opened by opening the front fence. The specific structure of the front fence is as follows: the front fence includes horizontal bars 37 arranged parallel to each other. The horizontal bars are connected by several vertical bars 38 arranged at intervals. The connection method can be welding. The two ends of the horizontal bars are provided with downward vertical inserts 39. The two vertical fence bars on the front side are provided with insert sleeves 40 corresponding to the vertical inserts. The opening or closing of the protective fence mechanism is realized by the insertion and disengagement between the vertical inserts and the insert sleeves.

[0035] In this embodiment, since there is a risk that the material may detach from the front and rear sides of the loading base plate due to unstable placement during the lifting process, a fixed protective railing 41 is welded between the rear sides of the two support columns on the loading base plate. This fixed protective railing can be installed by first welding it to the rear side of the loading base plate, and then welding the two sides of the fixed protective railing to the rear sides of the two support columns via bent rods. A hinged rotating movable guardrail 42 is connected between the front sides of the two support columns. The rotating movable guardrail allows material to enter and exit when it is necessary to place or remove material on the loading mechanism. Specifically, the rotating movable guardrail includes L-shaped rotating rods 43 symmetrically arranged on both sides. The horizontal part of the L-shaped flipping rod is on top and the vertical part is on the bottom. The horizontal end of the L-shaped flipping rod is hinged to the support column on the same side. Several horizontal connecting rods 44 are arranged between the vertical parts of the two L-shaped flipping rods from top to bottom. The ends of the vertical parts of the two L-shaped flipping rods abut against the front side of the loading base plate. The flipping of the L-shaped flipping rods drives the entire flipping movable guardrail to flip. At the same time, the support column can be equipped with existing buckles for locking the horizontal part of the L-shaped flipping rods, and the loading base plate can also be equipped with existing buckles for locking the bottom horizontal connecting rod, so as to fix the flipping movable guardrail when it is opened or closed. Of course, it is also possible to fix it directly by tying with ropes.
