Description

Technical Field

[0001] The utility model relates to the technical field of lifts, and more specifically to a wireless independently controlled two-column lift. Background Art

[0002] Domestic two-column car lifts are divided into mechanical and hydraulic types according to the transmission type. The working principle of the mechanical two-column lift is that there is a set of screw nut transmission structure in each column, and the sleeve roller chain hidden in the chassis transmits the connecting power between the two transmissions, so that the lifting systems in the two columns can rise synchronously. The working principle of the hydraulic lift is that the oil cylinder in the column drives the pulley through the main chain, and then the pulleys in the two columns rise and fall synchronously through the steel wire connected to the main slide.

[0003] The double-column lift needs to be synchronized. Currently, synchronous steel wire ropes are mainly used to restrain each other to achieve forced balance. The steel wire rope is not easy to adjust, and due to the small space between the columns, the rope-to-wheel ratio does not meet the requirements, the steel wire rope has a short life, etc. It is inconvenient to connect the oil pipe and steel wire rope during installation. At the same time, there are safety hazards such as the oil pipe and steel wire rope on the ground. Utility Model Content

[0036] The main column 100A and the auxiliary column 100B are both equipped with:

[0037] The movable bracket 200 is mounted on the driving rod 110 and moves linearly along the driving rod 110;

[0038] A support arm 300 is mounted on the movable bracket 200;

[0039] The control assembly 400 includes an operation panel 410, an electric control box 420, a proportional valve 430, a displacement sensor 440 and a wireless communication module;

[0040] The proportional valve is connected to the driving device 120 and is controlled by the electric control box 420; the displacement sensor 440 senses the moving height of the support arm 300;

[0041] like Figure 1As shown, the two lifts have the same structure and are used at the same time. The control components 400 of the main column 100A and the auxiliary column 100B are connected via a wireless communication module. The heights of the movable brackets 200 on the two lifts are detected by the displacement sensor 440, and the height information is transmitted to the control component 400 to control the two support arms 300 to operate synchronously, stably support the lifted objects, and prevent the two movable brackets 200 from being inconsistent in height.

Figure 1 As shown, after the movable bracket 200 moves upward, the movable bracket 210 extends out from the top of the main column 100A and the auxiliary column 100B.

[0044] Further, the support arm 300 is installed on the mobile frame 210; two groups of support arms 300 with the same structure are symmetrically installed on the mobile frame 210; the support arm 300 includes: a first support portion 310 and a second support portion 320, and the first support portion 310 and the mobile frame 210, the first support portion 310 and the second support portion 320 are connected through a gear assembly 330; Figure 2 As shown, the two groups of support arms 300 are symmetrically distributed and open at an angle;

[0045] Furthermore, if Figure 3-5 As shown, the gear assembly 330 includes: a gear 331 and a tooth block 332; the movable frame 210 is installed with a tooth block 332, and the beginning of the first support part 310 is provided with a gear 331, and the tooth block 332 and the gear 331 are meshed and connected; the end of the first support part 310 is provided with a tooth block 332, and the beginning of the second support part 320 is provided with a gear 331, and the gear 331 and the tooth block 332 are meshed and connected.

[0046] Then, the first support part 310 and the bracket 220 are limited by the engagement of the tooth block 332 and the gear 331. Similarly, the first support part 310 and the second support part 320 are limited by the engagement of the tooth block 332 and the gear 331, so as to stably support the lifted object.

[0047] Further, the first support part 310 swings relative to the moving frame 210, and the second support part 320 swings relative to the first support part 310; specifically, under external force or driven by some driving members, the first support part 310 swings relative to the moving frame 210, and the second support part 320 swings relative to the first support part 310 to adjust the angle;

[0048] An anti-slip member and / or a shock-absorbing member is disposed at the end of the second supporting portion 320 to better support the lifted object.

[0051] The use of the utility model is further described below:

[0052] After the two-post lift is started, the control components 400 of the two-post lift are connected via WiFi. When the support arm 300 rises, the support arms 300 on the main column 100A and the auxiliary column 100B need to run synchronously to stably support the lifted object. If the two support arms 300 are not synchronized, the lifted object is prone to fall and cause damage. Therefore, the displacement sensor 440 detects the height of the support arm 300 and feeds the information back to the electric control box 420. Through system analysis, it is determined whether the support arms 300 on the main column 100A and the auxiliary column 100B are synchronized. If not, a command is sent to the proportional valve 430, and the operation of the driving device 440 is adjusted through the proportional valve 430 to further control the rising speed of the support arms 300, so that the two groups of support arms 300 are synchronized.

[0053] Optionally, the control assembly 400 of the two-column lift can be defined as the control assembly 400 on the main column 100A as the main one, and the control assembly 400 on the auxiliary column 100A as the auxiliary one. When the displacement sensor 400 on the main column 100A senses the height A of the support arm 300, the height A is converted into a signal A and transmitted to the electric control box 420. When the displacement sensor 400 on the auxiliary column 100B senses the height B of the support arm 300, the height B is converted into a signal B and transmitted to the electric control box 420. , and then transmit signal B to the electric control box 420 of the main column 100A via WiFi. The electric control box 420 of the main column 100A analyzes and compares signal A and signal B. If the two are consistent, it continues to operate according to the current operating state. If the two are inconsistent, the electric control box 420 of the main column 100A sends a command to the proportional valve, and adjusts the operation of the driving device 440 through the proportional valve 430, so as to further control the rising speed of the support arm 300, so that the two groups of support arms 300 are synchronized.

[0054] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
