Description

Technical Field

[0001] This utility model relates to the field of lamp tube transfer technology, and in particular to a self-lifting lamp tube transfer trolley. Background Technology

[0002] In the production process of LED lights, the lamp tube is an essential component. After the lamp tube is coated with powder and dried on its inner wall, it needs to be transferred to the processing line using a transfer trolley.

[0003] Existing lamp transfer trolleys require lamps to be neatly placed on the trolley's loading platform. When placing the lamps manually, the platform is low, requiring the operator to bend over. Transferring the lamps to the loading bin on the processing line also requires manual bending over to retrieve them. Prolonged bending can easily cause chronic lumbar muscle strain for operators. Therefore, this application provides a self-lifting lamp transfer trolley to meet this need. Utility Model Content

[0004] The purpose of this application is to provide a self-lifting lamp transfer trolley to solve the technical problem that existing lamp transfer trolleys require bending over to pick up lamps.

[0005] To achieve the above objectives, this application provides the following technical solution: a self-lifting lamp tube transfer trolley, comprising a mobile frame, a loading plate on the mobile frame, and a gravity lifting unit for automatically lifting the loading plate. The gravity lifting unit comprises two hollow columns mounted on the mobile frame and arranged opposite to each other. The inner cavities of the two hollow columns each contain N identical weight blocks wrapped with an elastic buffer layer. Adjacent weight blocks are connected by a second pull rope. The lower end of the lowermost weight block is fixedly connected to the bottom of the inner cavity of the hollow column by the second pull rope. The upper end of the uppermost weight block is connected to the loading plate by a first pull rope. Two guide wheels are rotatably arranged on the mobile frame, and the two first pull ropes are respectively assembled with the corresponding guide wheels.

[0006] The cargo tray is slidably mounted on the mobile frame.

[0007] In a preferred embodiment of this invention, the upper and lower ends of the weight-adding block are provided with receiving grooves for accommodating the second pull rope.

[0008] In a preferred embodiment of this invention, N is not less than two groups. In the two uppermost weight-adding blocks, the lower end of the upper weight-adding block and the upper end of the lower weight-adding block are provided with multiple mounting grooves, and each mounting groove is provided with a magnet. The magnetic poles of the two opposing magnets are opposite.

[0009] In a preferred embodiment of this invention, the upper surface of the carrier plate is recessed, and a hollow cavity is provided on the carrier plate.

[0010] In a preferred embodiment of this invention, the upper end of each hollow column is provided with a sealing plate, and the upper end of the sealing plate is provided with a through hole adapted to the first pull rope.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] This utility model has a reasonable structure. The transfer trolley is equipped with a gravity lifting unit. This gravity lifting unit can automatically lift the loading plate as needed so that the operator can place and pick up the lamp tubes without bending over.

[0013] In this invention, the top two weight blocks are equipped with magnets. The top weight block is magnetically attracted and fixed to the bottom weight block to form a whole, thereby reducing the vibration amplitude of the top weight block and preventing violent collisions.

[0021] 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.

[0022] Example: Reference Figure 1-4 The self-lifting lamp transfer trolley shown includes a mobile frame 1, a carrying plate 2 on the mobile frame 1, and a gravity lifting unit for automatically lifting the carrying plate 2. The gravity lifting unit includes two hollow columns 3 mounted on the mobile frame 1 and arranged opposite each other. The inner cavity of each of the two hollow columns 3 is stacked with N weight blocks 5 of the same specification and wrapped with an elastic buffer layer 11. Adjacent weight blocks 5 are connected by a second pull rope 7. The lower end of the lowermost weight block 5 is fixedly connected to the bottom of the inner cavity of the hollow column 3 by the second pull rope 7. The upper end of the uppermost weight block 5 is connected to the carrying plate 2 by a first pull rope 4. Two guide wheels 10 are rotatably arranged on the mobile frame 1, and the two first pull ropes 4 are respectively assembled with the corresponding guide wheels 10.

[0023] The cargo tray 2 is slidably mounted on the mobile frame 1.

[0024] Initial state of the cart as follows Figure 1 As shown, after the operator can place the lamp tubes on the carrier plate 2 without bending over, once the lamp tubes have a certain weight, the weight of the carrier plate 2 and the lamp tubes will cause the top weight block 5 to move upward a certain distance via the first pull rope 4. This distance is the length of the second pull rope 7. At the same time, the carrier plate 2 will move downward a certain distance, reducing the height of the lamp tubes piled on it, making it easier for the operator to place the lamp tubes directly on the carrier plate while standing upright. As the weight continues to increase, when it reaches a certain weight, the second weight block 5 is pulled upward a certain distance, while the carrier plate 2 continues to move downward a certain distance, allowing the operator to... The operator can continue to stand and place the light tubes on the carrier plate 2. This process is repeated. As the weight on the carrier plate 2 increases, it will lower the carrier plate 2 by a certain height, making it easier for the operator to place the light tubes while standing upright. When the light tubes are removed from the carrier plate 2 and placed into the loading bin, the operator can stand upright to pick them up. As the number of light tubes on the carrier plate 2 decreases by a certain amount, the carrier plate 2 will automatically move upward a certain distance (correspondingly, the bottommost suspended weight block 5 will move downward and stack). This process is repeated, and the gravity lifting unit can automatically complete the lifting and lowering of the carrier plate 2 so that the operator can place and pick up the light tubes without bending over.

[0025] It should be noted that: First, when the trolley vibrates during movement, the collision between the weight blocks 5 can be buffered by the elastic buffer layer 11, reducing noise generation; Second, the movement of the weight blocks 5 within the hollow column 3 can effectively prevent the weight blocks 5 from swaying left and right, thus avoiding the inability to complete stacking and contributing to the stability of the carrying plate 2; Third, the hollow column 3 is provided in two sets, one on the left and one on the right, so that both sides of the carrying plate 2 can be subjected to force simultaneously during operation, which is conducive to the stable and smooth movement of the carrying plate 2.

[0026] In a preferred embodiment of this invention, the upper and lower ends of the weight block 5 are provided with receiving grooves 6 for accommodating the second pull rope 7.

[0027] When the weight-adding blocks 5 are stacked, the second pull rope 7 is accommodated by the receiving groove 6. The purpose is to avoid the collision between the weight-adding blocks 5 and the second pull rope 7 due to vehicle vibration, which would cause the second pull rope 7 to be squeezed and damaged, and to improve the service life of the second pull rope 7.

[0028] As a preferred embodiment of this example, Figure 4 and Figure 5 As shown, N is not less than two groups. In the two uppermost weight blocks 5, the lower end of the upper weight block 5 and the upper end of the lower weight block 5 are provided with multiple mounting grooves, and magnets 12 are provided in the mounting grooves. The magnetic poles of the two opposing magnets 12 are opposite.

[0029] When the vehicle body vibrates during movement, it often causes the topmost weight block 5 to move significantly (which can easily cause a violent collision). Therefore, a magnet 12 is installed so that the topmost weight block 5 is magnetically attracted and fixed to the bottom weight block 5 to form a whole, thereby reducing the vibration amplitude of the topmost weight block 5 and preventing violent collisions.

[0030] It should be noted that the resultant force of the relatively set magnets 12 is less than the weight of a single weight block 5. When a certain amount of light tubes are added to the carrier plate 2, the uppermost weight block 5 will move upward relative to the lower weight block 5.

[0031] As a preferred embodiment of this example, Figure 1 As shown, the upper end face of the carrier plate 2 is recessed, and a hollow cavity 9 is provided on the carrier plate 2.

[0032] The upper surface of the existing carrier plate 2 is generally set as a flat surface. When dealing with the remaining lamp tubes on the carrier plate 2, the operator needs to gather them together and then pick them up, which is quite troublesome. However, by setting the upper surface of the carrier plate 2 to be concave, it has a gathering effect on the lamp tubes placed on the carrier plate 2, making it easier for the operator to reach into the hollow cavity 9 and pick up the remaining lamp tubes on the carrier plate 2 in one go.

[0033] As a preferred embodiment of this example, Figure 1 As shown, the upper end of each hollow column 3 is provided with a sealing plate 8, and the upper end of the sealing plate 8 is provided with a through hole that is compatible with the first pull rope 4.

[0034] The function of the sealing plate 8 is to seal the upper end of the hollow column 3 to prevent dust and other debris from entering the hollow column 3 and avoid affecting the movement of the weight block 5.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
