Technical Field
[0001] The utility model relates to a double-girder bridge crane with high safety, belonging to the technical field of double-girder bridge cranes. Background Art
[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a hoist, belonging to material handling machinery. The working characteristic of a crane is intermittent movement, that is, in a working cycle, the corresponding mechanisms for actions such as material taking, transporting, and unloading work alternately. Existing double-girder bridge cranes generally have main and auxiliary hoisting mechanisms. The main hook is responsible for lifting heavy objects with large tonnages, and the auxiliary hook is responsible for lifting heavy objects with small tonnages.
[0003] During the use of existing double-girder bridge cranes, there are still some problems. For example, when carrying goods, since there is no protective device outside the hook, the goods will shake during movement. At the same time, when the starter is used for a long time, the nylon rope inside it will continuously rub, resulting in relatively loud noise. Content of the Utility Model
[0004] The purpose of the utility model is to provide a double-girder bridge crane with high safety. The structure of the utility model is simple and convenient to use. It can hold the goods being transported, prevent them from being positioned during movement, and at the same time can lubricate the rotating shaft at the bottom of the crane to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A double-girder bridge crane with high safety, including a beam bridge body. A controller is fixedly connected to the outside of the beam bridge body. An electric slider is slidably connected to the outside of the beam bridge body. A starter is fixedly connected to the top of the electric slider. A running box is fixedly connected between the electric sliders. A rotating shaft is rotatably connected to the inside of the running box. A nylon rope is wound around the outside of the rotating shaft. The bottom of the nylon rope is fixedly connected to a connecting plate. The bottom of the connecting plate is fixedly connected to a storage plate. A chute is opened inside the storage plate. A sliding rod is slidably connected to the inside of the chute. A return spring is fixedly connected to the outside of the sliding rod. A first protection plate and a second protection plate are fixedly connected to the top of the sliding rod. A fixing plate is fixedly connected to the outside of the first protection plate. A positioning hole is opened inside the fixing plate. An installation groove is opened inside the second protection plate. A movable tube is fixedly connected to the outside of the second protection plate. A clamping rod is movably connected to the inside of the movable tube. A pulling cover is fixedly connected to the outside of the clamping rod. A compression spring is fixedly connected to the inside of the pulling cover.
[0007] Further, a lubricant tank is fixedly connected to the top of the operation box. A display board is fixedly connected to the outside of the lubricant tank. A cover plate is snap-connected to the top of the lubricant tank. An extraction pump is fixedly connected to the outside of the lubricant tank. A conduit is fixedly connected to the bottom of the extraction pump. An oil outlet ring is fixedly connected to the bottom of the conduit.
[0008] Further, the starter is electrically connected to the controller, and a rotating shaft is fixedly connected to the output end of the starter.
[0009] Further, the nylon ropes are symmetrically distributed at the bottom of the operation box, and the connecting plates are symmetrically distributed at the top of the storage board.
[0010] Further, the first protection plate and the second protection plate are slidably connected to the top of the storage board, and one end of the clamping rod is located inside the positioning hole.
[0011] Further, the extraction pumps are symmetrically distributed on the outside of the lubricant tank, and the extraction pumps are electrically connected to the controller.
[0012] Further, the number of the conduits is the same as that of the oil outlet rings, and the oil outlet rings are located outside the rotating shaft.
[0013] The beneficial effects of the present utility model are as follows: (1) By providing a beam bridge body, the starter on the top of the electric slider is started through the controller. At this time, the storage board can move upward under the combined action of the rotating shaft and the nylon rope. Then, the electric slider is started through the controller, and it can move on the beam bridge body. On the top of the storage board, there are a first protection plate and a second protection plate. When it is necessary to carry goods, the sliding rod moves inside the sliding groove, so that the fixing plate on the outside of the first protection plate enters the installation groove inside the second protection plate. At this time, under the drive of the compression spring inside the pulling cover, the clamping rod enters the positioning hole inside the fixing plate, so as to connect the first protection plate and the second protection plate, achieving the effect of positioning the goods on the top of the storage board and preventing them from shaking during movement.
[0014] (2) By providing an electric slider, an operation box is fixedly connected between the electric sliders. When it is necessary to lubricate the rotating shaft inside the operation box, the extraction pump on the outside of the lubricant tank is started through the controller, so that the extraction pump extracts the lubricant inside the lubricant tank, and then enters the inside of the oil outlet ring through the conduit at the bottom of the extraction pump. Since the oil outlet ring is located outside the rotating shaft, the rotating shaft can be lubricated, achieving the effect of automatically adding lubricant and preventing the friction force from increasing when the nylon rope contracts.

[0022] Example 1 Please refer to Figures 1-4 and the present utility model provides a technical solution:
[0023] A high - security double - beam bridge crane, including a beam bridge body 1, a controller 2 is fixedly connected to the outer side of the beam bridge body 1, an electric slider 3 is slidably connected to the outer side of the beam bridge body 1, a starter 4 is fixedly connected to the top of the electric slider 3, a running box 5 is fixedly connected between the electric sliders 3, a rotating shaft 6 is rotatably connected to the inside of the running box 5, a nylon rope 7 is wound around the outer side of the rotating shaft 6, a connecting plate 8 is fixedly connected to the bottom of the nylon rope 7, a storage plate 9 is fixedly connected to the bottom of the connecting plate 8, a chute 10 is opened in the inside of the storage plate 9, a sliding rod 11 is slidably connected to the inside of the chute 10, a return spring 12 is fixedly connected to the outer side of the sliding rod 11, a first protection plate 13 and a second protection plate 14 are fixedly connected to the top of the sliding rod 11, a fixing plate 15 is fixedly connected to the outer side of the first protection plate 13, a positioning hole 16 is opened in the inside of the fixing plate 15, an installation groove 17 is opened in the inside of the second protection plate 14, a movable tube 18 is fixedly connected to the outer side of the second protection plate 14, a clamping rod 19 is movably connected to the inside of the movable tube 18, a pulling cover 20 is fixedly connected to the outer side of the clamping rod 19, and a compression spring 21 is fixedly connected to the inner side of the pulling cover 20.
[0024] Specifically, as Figure 1 shown, the starter 4 is electrically connected to the controller 2, and a rotating shaft 6 is fixedly connected to the output end of the starter 4. The nylon ropes 7 are symmetrically distributed at the bottom of the running box 5, the connecting plates 8 are symmetrically distributed at the top of the storage plate 9, the first protection plate 13 and the second protection plate 14 are slidably connected to the top of the storage plate 9, and one end of the clamping rod 19 is located inside the positioning hole 16.
[0025] In this implementation scheme: By setting the beam bridge body 1, the controller 2 starts the starter 4 at the top of the electric slider 3. At this time, the storage plate 9 can move upward under the combined use of the rotating shaft 6 and the nylon rope 7. Then, by the controller 2 starting the electric slider 3, it can move on the beam bridge body 1. And on the top of the storage plate 9, there are a first protection plate 13 and a second protection plate 14. When it is necessary to carry goods, the sliding rod 11 moves inside the chute 10, so that the fixing plate 15 on the outer side of the first protection plate 13 enters the installation groove 17 inside the second protection plate 14. At this time, driven by the compression spring 21 on the inner side of the pulling cover 20, the clamping rod 19 enters the positioning hole 16 inside the fixing plate 15, so as to connect the first protection plate 13 and the second protection plate 14, achieving the positioning of the goods on the top of the storage plate 9 and preventing them from shaking during movement.
[0026] Example 2 Please refer to Figure 1 、 Figure 2 and Figure 4, the difference between this embodiment and Embodiment 1 lies in that: a lubricant tank 22 is fixedly connected to the top of the operation box 5, a display board 23 is fixedly connected to the outside of the lubricant tank 22, a cover plate 24 is snap-connected to the top of the lubricant tank 22, an extraction pump 25 is fixedly connected to the outside of the lubricant tank 22, a conduit 26 is fixedly connected to the bottom of the extraction pump 25, and an oil outlet ring 27 is fixedly connected to the bottom of the conduit 26.
[0027] Specifically, as Figures 1-4 shown, the extraction pumps 25 are symmetrically distributed on the outside of the lubricant tank 22, and the extraction pumps 25 are electrically connected to the controller 2. The number of the conduits 26 is the same as that of the oil outlet rings 27, and the oil outlet rings 27 are located outside the rotating shaft 6.
[0028] In this implementation scheme: by setting the electric slider 3, the operation box 5 is fixedly connected between the electric sliders 3. When it is necessary to lubricate the rotating shaft 6 inside the operation box 5, the extraction pump 25 outside the lubricant tank 22 is started through the controller 2, so that the extraction pump 25 extracts the lubricant inside the lubricant tank 22, and then enters the inside of the oil outlet ring 27 through the conduit 26 at the bottom of the extraction pump 25. Since the oil outlet ring 27 is located outside the rotating shaft 6, the rotating shaft 6 can be lubricated, achieving the effect of automatically adding lubricant and preventing the friction force from increasing when the nylon rope 7 contracts.
[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
