Description

Technical Field

[0001] This utility model relates to the field of synchronous lifting device technology, and specifically to a synchronous lifting device. Background Technology

[0002] A synchronous lifter is a device that enables precise and synchronous lifting of multiple lifting units (such as platforms and supports), ensuring consistency and stability during the lifting process.

[0003] For example, one application discloses a rack and pinion synchronous lifter, including a support frame. A bearing portion is vertically slidably mounted on the support frame. Multiple drive components are mounted on the support frame to drive the bearing portion to slide vertically. Each drive component includes an extension frame fixedly connected to the support frame. A rack is vertically slidably mounted within the extension frame. The rack is fixedly connected to the bottom of the bearing portion via a connector. A drive gear is rotatably connected inside the extension frame, and the drive gear meshes with the rack. When a servo motor drives one transmission rod to rotate, it drives another transmission rod to rotate via a transmission mechanism, thus enabling the two transmission rods to rotate synchronously. This, in turn, drives the spur gear to rotate synchronously, which in turn drives the rack to slide synchronously, facilitating the adjustment of the lifting and lowering of the bearing portion.

[0004] However, in actual use, the gears and racks rub against each other continuously, and mechanical wear will occur after a period of time, which will affect the accuracy and stability of the synchronization adjustment, and lubrication is required.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a synchronous lifting device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: A synchronous lifting device includes a drive rod, a plurality of main gears fixedly connected to the drive rod, a rack meshing with the main gears, and a lubrication gear meshing with the rack; A liquid storage tank is provided above the lubricating gear, and an oil plug is provided inside the liquid storage tank. A lifting bracket is fixedly installed at the bottom of the oil plug, which can move up and down to open or close the liquid outlet of the liquid storage tank. A cam is mounted on the lubrication gear, and the lubrication gear drives the lifting bracket to move up and down via the cam.

[0008] Furthermore, the lifting bracket includes a connecting rod with one end fixedly connected to the oil plug and a ball installed at the other end of the connecting rod, the ball being in rolling contact with the cam.

[0009] Furthermore, an elastic element is provided between the oil plug and the top wall of the liquid storage tank.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0020] like Figures 1 to 5 As shown, the synchronous lifting device of this utility model includes a drive rod 101, a plurality of main gears 102 fixedly connected to the drive rod 101, racks 103 meshing with the main gears 102, and a lubrication gear 104 meshing with the racks 103. The drive rod 101 drives the plurality of main gears 102 to rotate, thereby driving the racks 103 to move synchronously upward or downward, thus realizing the synchronous lifting function of the racks 103. The lubrication gear 104 continuously provides lubrication during the movement of the racks 103, ensuring smooth operation of the main gears 102 and racks 103, reducing mechanical wear, and ensuring operational accuracy and operational stability.

[0021] A liquid storage tank 105 is provided above the lubrication gear 104. The liquid storage tank 105 contains lubricating oil. During the lifting and lowering of the rack 103, the lubricating oil in the liquid storage tank 105 drips onto the lubrication gear 104. Since the lifting and lowering of the rack 103 will drive the lubrication gear 104 to rotate, the rack 103 and the main gear 102 can be lubricated.

[0022] An oil plug 106 is provided at the outlet of the liquid storage tank 105. A lifting bracket 107 is fixedly installed at the bottom of the oil plug 106. A cam 108 is fixedly installed on the rotating shaft of the lubrication gear 104. The lubrication gear 104 drives the lifting bracket 107 to reciprocate through the cam 108, thereby driving the oil plug 106 to move so that the outlet opens or closes. By setting the lifting bracket 107 to drive the oil plug 106 to move and control the liquid output, the amount of oil output can be precisely controlled, ensuring the lubrication effect while reducing the waste of lubricating oil.

[0023] Specifically, the lifting bracket 107 includes a connecting rod 1071 and a ball 1072. One end of the connecting rod 1071 is fixedly connected to the oil plug 106, and the other end is fixedly connected to the ball 1072. The ball 1072 is in rolling contact with the cam 108. During the rotation of the lubrication gear 104, the cam 108 will be driven to rotate. During the rotation of the cam 108, the lifting bracket 107 will be driven to move up or down, thereby driving the oil plug 106 to move to open or close the liquid outlet.

[0024] It should be noted that the lifting bracket 107 and the cam 108 are both provided in two sets and are symmetrically arranged on both sides of the lubrication gear 104 to ensure that the oil plug 106 is subjected to uniform force during movement and has better stability.

[0025] It should also be noted that an elastic element 109 is installed between the surface of the oil plug 106 and the top wall of the liquid storage tank. The elastic element 109 is a spring. When the lifting bracket 107 moves the oil plug 106 upward to open the liquid outlet, the spring is compressed. When the oil plug 106 moves downward, the oil plug 106 will automatically return to its original position under the action of the spring force, thereby ensuring the stable movement of the oil plug 106.

[0026] In another embodiment, a sliding sleeve 110 is fixedly installed on the surface of the oil plug 106, and a sliding rod 111 is fixedly installed on the top wall of the liquid storage tank. The sliding rod 111 slides in contact with the sliding sleeve 110, and the spring is sleeved on the outside of the sliding rod 111. During the movement of the oil plug 106, the sliding sleeve 110 will move along the sliding rod 111, which can guide and support the movement of the oil plug 106 and further improve its operational stability.

[0027] In another embodiment, a collection box 112 is provided on the support frame 117 below the lubrication gear 104. The collection box 112 is used to collect lubricating oil dripping from the lubrication gear 104. The collection box 112 can effectively prevent lubricating oil from dripping everywhere, reduce lubricating oil waste, and also keep the working environment clean.

[0028] The top of the collection box 112 is provided with a liquid inlet, and a filter screen 113 is fixedly installed at the liquid inlet. The filter screen 113 can filter the lubricating oil and remove impurities adhering to the lubricating gear 104, which facilitates subsequent processing.

[0029] It should be added that the filter screen 113 is tilted so that the lubricating oil can flow smoothly into the collection box 112, and at the same time it is conducive to the sliding and accumulation of impurities on the surface of the filter screen 113, making it convenient to clean the filter screen 113 regularly.

[0030] In addition, a fixed base 114 is provided in this application, the main gear 102 is rotatably installed in the fixed base 114, the drive rod 101 passes through the fixed base 114 and is rotatably connected to it through a bearing; bushings 115 are fixedly installed on the top and bottom of the fixed base 114, and the rack 103 slides in contact with the bushings 115.

[0031] Specifically, a guide slide 116 is fixedly installed on the outer side of the gear, and a slide groove is provided on the inner side wall of the bushing 115. The guide slide 116 slides in contact with the slide groove to guide the rack 103 during its movement, ensuring that the rack 103 remains stable during its movement and avoiding instability caused by deviation or vibration of the movement trajectory, thus ensuring that the entire device can operate efficiently and stably.

[0032] A support frame 117 is installed on the fixed base 114. The lubrication gear 104 is rotatably connected to the support frame 117 through a bearing. The liquid storage tank 105 and the collection tank 112 are both installed on the support frame 117.

[0033] Working principle: The drive rod 101 drives several main gears 102 to rotate, thereby causing the racks 103 to move synchronously upward or downward, thus realizing the synchronous lifting and lowering function of the racks 103. The lubrication gear 104 continuously provides lubrication during the movement of the racks 103, ensuring smooth operation of the main gears 102 and racks 103, reducing mechanical wear, and ensuring operational accuracy and stability.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
