Description

A lift with two-way transportation function Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an elevator with a bidirectional transportation function. Background Art

[0002] A construction hoist is a professional equipment used in construction sites. It is designed to simplify the vertical transportation of materials and workers inside and outside buildings. The elevator usually consists of a platform and an electric device. The platform can accommodate a large number of objects or people, and the electric device is used to move the platform up and down in the vertical direction. Construction elevators can effectively improve construction efficiency and eliminate the need for workers to manually carry bricks and other building materials. The elevator also improves the safety of the construction site. Since building materials no longer need to be transported by stairs or manual lifting, the risk of workers being injured by carrying heavy objects can be reduced. However, when transporting items, existing elevators need to manually move the materials one by one out of the elevator after they are raised to a high place, which requires the elevator to remain fixed at a high altitude for a long time, increasing the work done by the electric device and also affecting the construction efficiency of the construction site.

DETAILED DESCRIPTION

[0025] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0027] In embodiment 1, as shown in FIG1 , a lift with a bidirectional transport function includes the following contents:

[0028] A base 8 is provided with a door-shaped bracket 1 on the top of the base 8, and a lifting component is provided on the crossbeam of the bracket 1. The lifting component is used to drive the lifting plate 13 to lift and lower in the vertical direction. A guardrail 5 is provided on the top of the lifting plate 13. The guardrail 5 is a U-shaped structure with one side open. A placement component is provided in the guardrail 5. The placement component is used to place materials. A buffer component is provided at the center of the base 8, and the buffer component is located at the bottom of the lifting plate 13.

[0029] In this solution, by placing the material on the placement component and then using the lifting component to drive the placement component to move in the vertical direction, the material can be brought to a high place. If the placement component falls quickly to the bottom of the door-shaped bracket, the buffer component can be used to reduce the impact force of the placement device on the base, thereby reducing damage to people or materials in the placement device.

[0030] More specifically, the placement assembly includes a placement plate 6, and a plurality of groups of rollers 7 that are rotatably installed on the top of the placement plate 6 and are distributed in parallel and located in the same plane. The rollers 7 are protruding from the top of the placement plate 6, and the bottom of the placement plate 6 is tilted. The bottom end of the placement plate 6 is set away from the opening of the guardrail 5, the thickest end of the placement plate 6 is rotatably connected to the guardrail 5, and a support device is provided at the bottom of the thinnest end of the placement plate 6.

[0031] Due to the setting of the roller, the external force required to remove the material from the placement plate can be greatly reduced, and the bottom of the placement plate is set at an angle, and a support device is provided at the lowest end of the placement plate. By manipulating the support device, an angle is formed between the top of the placement plate and the horizontal plane. When the angle is large, the material can even roll down from the top of the placement plate due to the rotation of the roller on the surface of the placement plate under the action of gravity, which reduces the time required for unloading the material, reduces the work done by the lifting component, and can also effectively improve the construction efficiency of the construction site.

[0032] As shown in Figure 2, more specifically, the supporting device includes a first hinge seat 14, an adjusting rod 15 and an extension rod 18. The first hinge seat 14 is fixedly installed at the bottom of the placement plate 6. The first hinge seat 14 is hinged with the adjusting rod 15 at one end away from the placement plate 6. The bottom of the hinge rod is pluggably connected to the extension rod 18. The end of the extension rod 18 away from the hinge rod is provided with an anti-slip pad 19.

[0033] By adjusting the distance that the adjusting rod extends into the extension rod, the top of the placement plate can be made to form an angle with the horizontal plane, so that the material can be piled on the roller or slide down from the top of the placement plate. When the adjusting rod extends into the extension rod for a longer distance, the placement plate tilts downward toward the side of the guardrail opening, and the material can slide down from the top of the placement plate. When the material extends into the extension rod for a shorter distance, the side of the placement plate away from the guardrail opening tilts downward, and the material can be caught by the guardrail to prevent the material from falling off the placement plate.

[0034] As shown in Figure 4, more specifically, the extension rod 18 is sleeved on the outside of the hinged rod, and the extension rod 18 is provided with a connecting head at one end close to the hinged rod. The connecting head includes a connecting pipe 16 and a fastening joint 17. The fastening joint 17 is a cylindrical "T"-shaped structure with a hollow interior. The fastening joint 17 is connected to the extension rod 18, and the fastening joint 17 is externally threaded with a connecting pipe 16.

[0035] By rotating the connecting pipe, the fastening joint can be opened or closed. After the fastening joint is opened, the pressure of the fastening joint on the adjusting rod is reduced, and the adjusting rod can slide inside the extension rod. After the fastening structure is closed, the pressure on the adjusting rod is increased, and the adjusting rod and the extension rod are fixed to each other.

[0036] As shown in Figure 3, more specifically, a connecting rod 20 is provided at the bottom of the thickest end of the placement plate 6, and a second hinge seat 21 is provided at the top of the lifting plate 13. The end of the connecting rod 20 away from the placement plate 6 is hinged to the second hinge seat 21.

[0037] The placement plate can be hinged to the lifting plate through the connecting rod and the hinge seat, which facilitates the rotation of the placement plate on the lifting plate.

[0038] More specifically, the lifting assembly includes a winch 4, which is provided in multiple groups and fixedly mounted on the crossbeam of the bracket 1. The winch 4 is distributed at both ends of the crossbeam of the bracket 1, and the winch 4 is wound with a steel wire rope. The end of the steel wire rope away from the winch 4 is vertically downward and fixedly connected to the side wall of the lifting plate 13.

[0039] Multiple sets of winches simultaneously reel in or release the wire rope. When the wire rope is released, the lifting plate moves steadily downward. When the wire rope is reeled in, the lifting plate moves upward under the pull of the wire rope, thereby realizing the lifting of the elevator.

[0040] More specifically, the lifting assembly also includes a guide rod 2, one end of the guide rod 2 is fixedly connected to the crossbeam of the bracket 1, and the other end of the guide rod 2 is fixedly connected to the base 8. The guide rod 2 passes through the four corners of the lifting plate 13 and is slidably connected to the lifting plate 13.

[0041] The guide rod is used to limit and guide the lifting plate, thereby ensuring that the lifting plate moves stably in the vertical direction and avoiding side shaking during the up and down movement of the lifting plate, thereby improving stability during subsequent use and facilitating use.

[0042] As shown in Figure 5, more specifically, the buffer assembly includes a bottom plate 11, which is embedded in the base 8. A linkage assembly is provided on the top of the bottom plate 11. The bottom plate 11 is connected to a buffer plate 9 through the linkage assembly, and the buffer plate 9 is in conflict with the lifting plate 13.

[0043] More specifically, the linkage assembly includes a buffer rod 10, a sliding rod 23 and a slider 22. A sliding groove is provided at the top of the base plate 11, and the sliding rod 23 is installed in the sliding groove. The surface of the sliding rod 23 is slidably connected to the slider 22. There are two sliders 22, and the two sliders 22 are installed at both ends of the sliding rod 23. One end of the buffer rod 10 is hinged to one of the sliders 22, and the other end of the buffer rod 10 is hinged to the buffer plate 9. Both ends of the sliding rod 23 are provided with a return spring 24. The return spring 24 and the sliding rod 23 are provided with two. The two sliding rods 23 are installed on both sides of the base plate 11. When the two sliders 22 slide in opposite directions, the return spring 24 is compressed.

[0044] When the elevator moves downward, it collides with the buffer plate, and the buffer plate moves downward under the force, squeezing the linkage assembly. The end of the buffer rod connected to the slider slides toward the two ends of the slide rod, squeezing the compression spring. The compression spring can buffer the force on the buffer plate, reduce the impact force when the elevator plate falls, and improve the safety of the elevator.

[0045] More specifically, a resilient material 12 is provided on the top of the bottom plate 11 , and the resilient material 12 contacts the buffer plate 9 .

[0046] The rebound material here can be a silicone block.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
