Description

Technical Field

[0001] This utility model relates to the field of mechanical device fixing brackets, specifically a lifting type small agricultural machinery combination bracket. Background Technology

[0002] Lifting platforms are a widely used tool in the construction industry. In addition to transporting goods at different heights, they are also frequently used for high-altitude operations such as construction and municipal maintenance.

[0003] Chinese Patent Publication No. CN208202506U discloses a lifting support frame, including support columns, a base plate, and a lifting platform. A set of support columns is provided, and the base plate is horizontally connected to the top of the set of support columns. Grooves are formed on both sides of the top surface of the base plate. The lifting platform is installed on the top of the base plate, located between two grooves. Guided and stabilizing lifting devices are installed in the two grooves respectively. A connecting rod connects the guided and stabilizing lifting devices to the lifting platform; the lower end of the connecting rod is hinged to the lifting platform, and the middle part of the connecting rod is hinged to the guided and stabilizing lifting device. On the base plate outside the two grooves, a pulley device and a cable winding device are installed sequentially from the inside out. A cable is provided between the pulley device and the guided and stabilizing lifting device. One end of the cable is connected to the cable winding device, and the other end passes through the pulley device and connects to the upper end of the connecting rod. This invention solves the technical problem of unstable lifting in traditional lifting platforms, which easily leads to safety accidents.

[0004] The aforementioned patented device structure for platform lifting may cause the lifting platform to exceed its load-bearing capacity when carrying a particularly heavy object. During the lifting process, the lifting structure may malfunction, causing the lifting platform to fall rapidly. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting-type small agricultural machinery combination support. A first through-pipe is installed on the ground-contact base, and a connecting block is installed on one side of the first through-pipe. A second through-pipe is installed at the end of the connecting block away from the first through-pipe. A through hole is opened at the upper end of the first through-pipe, and the bottoms of the first and second through-pipes are connected. A non-Newtonian fluid is placed inside both the first and second through-pipes. A rectangular groove is opened on one side of the upper end of the second through-pipe, and a sealing gasket is installed on the non-Newtonian fluid. A connecting post is installed on the sealing gasket, and a lifting platform is installed at the end of the connecting post away from the sealing gasket. When the electronically controlled slider malfunctions, causing the lifting platform to suddenly plunge downwards, the sealing gasket applies enormous pressure to the non-Newtonian fluid. Due to the unique physical properties of the non-Newtonian fluid, it instantly hardens, causing the lifting platform to stop plunging downwards. After the lifting platform stops descending, the pressure applied by the sealing gasket to the non-Newtonian fluid decreases, at which point the sealing gasket squeezes the non-Newtonian fluid into the first through-pipe, causing the lifting platform to descend slowly. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting-type small agricultural machinery combination support, including a ground contact base, a first through pipe on the ground contact base, a connecting block on one side of the outer surface of the first through pipe, and a second through pipe, the second through pipe being disposed at the end of the connecting block away from the first through pipe, a non-Newtonian fluid being disposed inside the second through pipe, a sealing gasket being disposed on the non-Newtonian fluid, a connecting column being disposed at the upper end of the sealing gasket, and a lifting platform being disposed at the end of the connecting column away from the sealing gasket.

[0007] Preferably, a second bracket is provided on both sides of the ground contact base, and the second bracket is welded to the ground contact base.

[0008] Preferably, the second bracket is provided with a guide rail, and the guide rail is bolted to the second bracket.

[0009] Preferably, an electrically controlled slider is provided inside the guide rail, and one end of the electrically controlled slider is connected to the lifting platform.

[0010] Preferably, the upper end of the first conduit has a through hole.

[0011] Preferably, the ground contact base is provided with a first bracket at both the front and rear ends.

[0012] Preferably, a second rubber pad is provided at the lower end of the ground contact base.

[0013] Preferably, a first rubber pad is provided at the lower end of the lifting platform.

[0014] Preferably, the upper outer surface of the lifting platform is provided with anti-slip patterns.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention comprises a first through pipe mounted on a ground-contact base, a connecting block on one side of the first through pipe, and a second through pipe at the end of the connecting block away from the first through pipe. The upper end of the first through pipe has a through hole, and the bottoms of the first and second through pipes are connected. A non-Newtonian fluid is contained within both the first and second through pipes. A rectangular groove is formed on one side of the upper end of the second through pipe, and a sealing gasket is placed on the non-Newtonian fluid within the second through pipe. A connecting post is mounted on the sealing gasket, and a lifting platform is mounted at the end of the connecting post away from the sealing gasket. When a malfunction in the electrically controlled slider causes the lifting platform to violently lurch downwards, the sealing gasket... The gasket applies enormous pressure to the non-Newtonian fluid, and due to the unique physical properties of the non-Newtonian fluid, it hardens instantly, causing the lifting platform to stop its downward surge. Once the lifting platform stops descending, the pressure applied by the gasket to the non-Newtonian fluid decreases, at which point the gasket forces the non-Newtonian fluid into the first through pipe, causing the lifting platform to descend slowly. This effectively avoids the problem in existing platform lifting devices where, if a particularly heavy object is being lifted, the lifting platform exceeds its load capacity, causing the lifting structure to malfunction and resulting in a rapid drop during the lifting process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the problem in existing platform lifting devices where the lifting platform exceeds its load capacity when carrying exceptionally heavy objects, causing the lifting structure to malfunction and fall rapidly during lifting, this embodiment provides the following technical solution:

[0024] A lifting-type small agricultural machinery combination support includes a ground-contact base 1, a first through pipe 2 disposed on the ground-contact base 1, a connecting block 3 disposed on one side of the outer surface of the first through pipe 2, and a second through pipe 4 disposed at the end of the connecting block 3 away from the first through pipe 2. A non-Newtonian fluid 7 is disposed inside the second through pipe 4, a sealing gasket 8 is disposed on the non-Newtonian fluid 7, a connecting post 9 is disposed at the upper end of the sealing gasket 8, and a lifting platform 10 is disposed at the end of the connecting post 9 away from the sealing gasket 8. Second supports are disposed on both sides of the ground-contact base 1. 12. The second bracket 12 is welded to the ground base 1. A guide rail 13 is provided on the second bracket 12. The guide rail 13 is bolted to the second bracket 12. An electric control slider 14 is provided inside the guide rail 13. One end of the electric control slider 14 is connected to the lifting platform 10. A through hole 6 is opened at the upper end of the first through pipe 2. The first bracket 11 is provided at both the front and rear ends of the ground base 1. A second rubber pad 17 is provided at the lower end of the ground base 1. A first rubber pad 16 is provided at the lower end of the lifting platform 10. An anti-slip pattern 10 is provided on the outer surface of the upper end of the lifting platform 10.

[0025] In this embodiment, please refer to Figures 1-4 When the electronically controlled slider 14 malfunctions and causes the lifting platform 10 to lurch downwards, the sealing gasket 8 applies enormous pressure to the non-Newtonian fluid 7. Due to the unique physical properties of the non-Newtonian fluid 7, it hardens instantly, causing the lifting platform 10 to stop lurching downwards. After the lifting platform 10 stops descending, the pressure applied by the sealing gasket 8 to the non-Newtonian fluid 7 decreases. At this time, the sealing gasket 8 will squeeze the non-Newtonian fluid 7 into the first through pipe 2, causing the lifting platform 10 to descend slowly.

[0026] Working principle: The operator first uses a forklift or gantry crane to place the device or item between the first support 11 and the second support 12, and then places it inside the lifting platform 10. The first support 11 and the second support 12 can prevent the device on the lifting platform 10 from falling off the lifting platform 10 during transportation, and play a limiting and fixing role. When the electric control slider 14 malfunctions and causes the lifting platform 10 to rush downwards, the sealing gasket 8 applies huge pressure to the non-Newtonian fluid 7. Due to the unique physical properties of the non-Newtonian fluid 7, it will harden instantly, increasing its hardness, which will stop the lifting platform 10 from rushing downwards. After the lifting platform 10 stops descending, the pressure applied by the sealing gasket 8 to the non-Newtonian fluid 7 decreases. At this time, the sealing gasket 8 will squeeze the non-Newtonian fluid 7 into the first through pipe 2, causing the lifting platform 10 to descend slowly.
