Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an elevator with high transmission efficiency. Background Art

[0002] Logistics elevators are equipment used for loading and unloading goods. They not only improve the efficiency of loading and unloading goods, but also reduce the burden on workers. Most existing logistics elevators use sprocket and chain transmission, which is common in many mechanical equipment because they can provide a relatively simple, economical and reliable transmission solution.

[0003] However, the sprocket chain transmission method still has certain problems. For example, the sprocket chain transmission generates noise and may wear out after long-term use, requiring regular maintenance and replacement. In addition, the sprocket chain transmission process has high friction and low transmission efficiency. Therefore, it is urgent to design a hoist with high transmission efficiency to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a hoist with high transmission efficiency to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hoist with high transmission efficiency, comprising:

[0006] An integral frame, the integral frame comprising a hoist frame and a base fixed to the bottom of the hoist frame by bolts, wherein a linear guide rail is fixed to one side of the hoist frame in a vertical direction;

[0007] A lifting mechanism, comprising a mounting seat fixed to the top of the hoist frame, a reducer fixed to the top of the mounting seat, a lifting motor connected to the reducer, and a ball screw penetrating the mounting seat in a vertical direction and connected to the output shaft of the reducer through a coupling, wherein the bottom end of the ball screw is connected to the base through a bearing seat, a nut seat is provided on the ball screw, a connecting seat is fixed on the nut seat, a lifting trolley is fixed to one side of the connecting seat, and a guide shoe is provided on one side of the lifting trolley for sliding connection with the linear guide rail;

[0008] The conveying mechanism is arranged on the top of the lifting trolley.

[0009] Furthermore, the base includes a bottom plate and expansion bolts arranged on both sides of the bottom plate.

[0010] Furthermore, there are two linear guide rails, which are fixed on both sides of the same surface of the elevator frame.

[0011] Furthermore, the conveying mechanism includes a mounting plate fixed on the top of the lifting trolley, side fixing plates are fixed on the left and right sides of the mounting plate, a conveying motor is fixed on the top of the mounting plate, a transmission shaft is provided between the two side fixing plates, a driving wheel is provided at the output end of the conveying motor, a driven wheel is provided on the transmission shaft, and the driving wheel and the driven wheel are connected by a chain transmission.

[0012] Furthermore, sprockets are provided at both ends of the outer side of the side fixing plate, and the two sprockets corresponding to the transmission shaft are respectively connected to the keys at both ends of the transmission shaft. The four sprockets have the same horizontal height, and the two sprockets located on the same side fixing plate are connected through the drag chain plate.

[0013] Furthermore, a cover plate is fixed on the top of the side fixing plate, and the horizontal height of the cover plate is not higher than the horizontal height of the drag chain plate.

[0014] Furthermore, three trolley guard plates are provided on the outside of the conveying mechanism, and two adjacent trolley guard plates are fixedly connected by a U-shaped guard plate connecting plate.

[0015] The technical effects and advantages of the utility model are as follows: the hoist with high transmission efficiency has advanced design, compact structure and easy use. The traditional sprocket chain transmission is replaced by the transmission method of ball screw and linear guide. The ball screw has a lower friction coefficient and can therefore provide smoother and more precise motion control. The linear guide can ensure the stability and accuracy of the motion. Compared with the sprocket chain transmission, the transmission design of ball screw plus linear guide has obvious advantages in reducing noise and wear, and has higher transmission efficiency. The improvement of transmission efficiency can more effectively complete the task of lifting and lowering goods, thereby improving the operating efficiency and reliability of the entire system.

Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] The utility model provides Figure 1-6 A high transmission efficiency hoist shown in , comprising:

[0027] The overall frame 100 includes a hoist frame 101 and a base 102 fixed to the bottom of the hoist frame 101 by bolts. A linear guide rail 103 is fixed to one side of the hoist frame 101 in the vertical direction;

[0028] The lifting mechanism 200 includes a mounting seat 201 fixed to the top of the lifting machine frame 101, a reducer 203 fixed to the top of the mounting seat, a lifting motor 202 connected to the reducer 203, and a ball screw 205 that passes through the mounting seat 201 in the vertical direction and is connected to the output shaft of the reducer 203 through a coupling 204. The bottom end of the ball screw 205 is connected to the base 102 through a bearing seat 206. A nut seat 207 is provided on the ball screw 205. A connecting seat 208 is fixed to the nut seat 207. A lifting trolley 209 is fixed to one side of the connecting seat 208. A guide shoe 2091 that is slidably connected to the linear guide rail 103 is provided on one side of the lifting trolley 209.

[0029] The conveying mechanism 300 is arranged on the top of the lifting trolley 209.

[0030] For example, see Figure 1 As shown, the base 102 includes a bottom plate 1021 and expansion bolts 1022 arranged on both sides of the bottom plate 1021 .

[0031] In this technical solution, the base plate 1021 can provide a stable and solid support for the elevator frame 101, and the expansion bolts 1022 pass through both sides of the base plate 1021, making it convenient to fix the base plate 1021 to the ground, thereby ensuring the overall stability of the elevator.

[0032] For example, see Figure 1-3 As shown, there are two linear guide rails 103 , which are fixed on both sides of the same surface of the elevator frame 101 .

[0033] In this technical solution, two linear guide rails 103 are respectively arranged corresponding to the guide shoes 2091 on both sides of the lifting trolley 209, so that the lifting trolley 209 can slide up and down along the two linear guide rails 103. Compared with sliding along a single linear guide rail 103, the stability and reliability of the operation of the lifting trolley 209 are greatly improved.

[0034] For example, see Figure 2As shown, the conveying mechanism 300 includes a mounting plate 301 fixed on the top of the lifting trolley 209, side fixing plates 302 are fixed on the left and right sides of the mounting plate 301, a conveying motor 303 is fixed on the top of the mounting plate 301, a transmission shaft 304 is provided between the two side fixing plates 302, a driving wheel 305 is provided at the output end of the conveying motor 303, a driven wheel 306 is provided on the transmission shaft 304, and the driving wheel 305 and the driven wheel 306 are connected by a chain 307.

[0035] In this technical solution, the power of the conveying motor 303 is transmitted to the driven wheel 306 through the chain 307 , and then transmitted to the transmission shaft 304 through the driven wheel 306 .

[0036] For example, see Figure 2 As shown, sprockets 308 are provided at both ends of the outer side of the side fixing plate 302, and the two sprockets 308 corresponding to the transmission shaft 304 are respectively connected to the keys at both ends of the transmission shaft 304. The horizontal heights of the four sprockets 308 are the same, and the two sprockets 308 located on the same side fixing plate 302 are connected through the drag chain plate 309.

[0037] In this technical solution, the transmission shaft 304 can drive the sprockets 308 at both ends to rotate together. The sprocket 308 on the transmission shaft 304 drives the sprocket 308 on the side fixed plate 302 to rotate through the drag chain plate 309, so that the drag chain plate 309 can rotate around the two sprockets 308 on the same side.

[0038] For example, see Figure 1 As shown, a cover plate 312 is fixed on the top of the side fixing plate 302 , and the horizontal height of the cover plate 312 is not higher than the horizontal height of the drag chain plate 309 .

[0039] In this technical solution, it is ensured that the goods placed on the cover plate 312 can contact the drag chain plate 309, so that the drag chain plate 309 can drive the goods to move and transport them to the designated location.

[0040] For example, see Figure 2 and Figure 6 As shown, three trolley guard plates 310 are provided on the outer side of the conveying mechanism 300 , and two adjacent trolley guard plates 310 are fixedly connected by a U-shaped guard plate connecting plate 311 .

[0041] In this technical solution, adjacent trolley guard plates 310 are connected into one through a guard plate connecting plate 311, which is beneficial to improving the stability of the installation of the trolley guard plate 310 and thereby enhancing its anti-collision ability. By setting the trolley guard plate 310, the drag chain plate 309 can be prevented from being directly hit, which is beneficial to extending its service life.

[0042] Working principle: When the high transmission efficiency elevator is used, the goods are first transported to the cover plate 312 on the top of the conveying mechanism 300, and then the lifting motor 202 is started. After the lifting motor 202 is decelerated by the reducer 203, the ball screw 205 is driven to rotate through the coupling 204. At this time, the nut seat 207 on the ball screw 205 moves upward (or downward) along the ball screw 205, and then drives the connecting seat 208 to move upward (or downward), and finally realizes the up and down movement of the lifting trolley 209. When the lifting trolley 209 is lifted to the specified height, the lifting motor 202 is turned off, and the conveying motor 303 is started at the same time. The conveying motor 303 drives the drag chain plate 309 to rotate through the transmission shaft 304 and the sprocket 308, and then moves the goods to the specified position. This high-transmission-efficiency elevator has an advanced design, compact structure, and is easy to use. The traditional sprocket chain transmission is replaced by a transmission method of a ball screw 205 combined with a linear guide 103. The ball screw 205 has a lower friction coefficient, so it can provide smoother and more precise motion control, and the linear guide can ensure the stability and accuracy of the motion. Compared with the sprocket chain transmission, the transmission design of the ball screw 205 plus the linear guide 103 has obvious advantages in reducing noise and wear, and has higher transmission efficiency. The improvement in transmission efficiency can more effectively complete the task of lifting and lowering goods, thereby improving the operating efficiency and reliability of the entire system.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
