Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of belt conveyors, specifically relating to a lifting bracket that facilitates the replacement of idlers. Background Technology
[0002] In belt conveyors, the belt is supported by idlers. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemical, and steel. After prolonged use, due to the weight of the conveyed materials, the idlers experience wear as the belt passes over them. Regular maintenance and replacement of the idlers are necessary, requiring the use of lifting frames to elevate the belt.
[0003] Existing lifting frames often use lead screws to adjust the height. However, the movement of the lead screw with the slider requires a lot of physical labor from the workers, and the replacement of the idler rollers is time-consuming. At the same time, since the belt is often V-shaped, the side guard plate of the belt support hinders the entry and exit of the lifting frame. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a lifting bracket that facilitates the replacement of idler rollers. The specific technical solution is as follows:
[0005] A lifting bracket for easy replacement of idler rollers includes a hydraulic drive component, a driven component, a connecting rod, and a connecting hole. At least one driven component is provided, and the driven component is arranged parallel to the side of the hydraulic drive component. Both the hydraulic drive component and the driven component are provided with connecting holes, and a connecting rod for connecting the hydraulic drive component and the driven component is installed in the connecting hole.
[0006] Both the hydraulic drive component and the driven component include a base plate and a push rod arranged in parallel. Side guard plates are rotatably mounted on both ends of the push rod. Two symmetrically arranged lower rotating rods are rotatably mounted on the upper surface of the base plate. Two symmetrically arranged upper rotating rods are rotatably mounted on the lower surface of the push rod. A rotating rod joint is rotatably mounted between the upper rotating rod and the lower rotating rod. A side guard rod is rotatably mounted on the lower surface of the side guard plate. The lower end of the side guard rod is rotatably mounted in the middle of the lower rotating rod. The two base plates, the two push rods, and the two side guard plates are all connected by connecting rods.
[0007] The hydraulic drive unit also includes a hydraulic cylinder for lifting and lowering, which is installed between the base plate and the top rod.
[0008] Furthermore, connection holes are provided on the base plate, top rod, and side guard plate, and the connection holes provided on the hydraulic drive component and the driven component correspond one-to-one.
[0009] Furthermore, the upper and lower rotating rods are of equal length, and the rotating rod joint is vertically positioned between the base plate and the top rod. The side guard plate, upper rotating rod, lower rotating rod, and side guard rod form a quadrilateral.
[0010] Furthermore, the base plate has end plates integrally formed at both ends.
[0011] Furthermore, the width of the end plate is twice that of the base plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing at least one driven member, and connecting the hydraulic drive member and the driven member through a connecting rod, it is convenient for the driven member to follow the hydraulic drive member in raising and lowering the belt when the hydraulic drive member lifts it. This increases the balance of the hydraulic drive member during lifting and lowering, and increases the contact area during belt lifting. Both the hydraulic drive member and the driven member consist of a base plate, a push rod, a side guard plate, an upper rotating rod, a lower rotating rod, a rotating rod joint, and a side guard rod. The hydraulic drive member is also equipped with a hydraulic cylinder for lifting and lowering, facilitating the lifting and lowering of the hydraulic drive member by the hydraulic cylinder carrying the push rod. The two base plates, two top rods, and two side guard plates of the moving component are all connected by connecting rods, so that the hydraulic drive component can lift and lower the driven component, and the top rod can lift the belt. The base plate and the top rod are connected by an upper rotating rod, a lower rotating rod, and a rotating rod joint, so that the top rod can maintain the balance at both ends when it is lifted and lowered. The side guard rod is rotatably installed between the lower rotating rod and the side guard plate, so that when the lower rotating rod rotates, it drives the side guard plate to rotate through the side guard rod. Thus, when the top rod is lifted and lowered, the side guard plate is turned towards the top rod under the action of the side guard rod, so that the "V" shaped belt can be better supported by the top rod and the side guard plate, which makes it easier to enter the belt conveyor before the lifting frame is raised, and facilitates the replacement of the idler roller after the belt is raised.

[0018] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.
[0019] Please see Figure 1-4 This embodiment provides the following technical solution: a lifting bracket for easy replacement of idler rollers, including a hydraulic drive component 1, a driven component 2, a connecting rod 3 and a connecting hole 4. At least one driven component 2 is provided, and the driven component 2 is arranged parallel to the side of the hydraulic drive component 1. Both the hydraulic drive component 1 and the driven component 2 are provided with connecting holes 4, and a connecting rod 3 for connecting the hydraulic drive component 1 and the driven component 2 is installed in the connecting hole 4.
[0020] Both the hydraulic drive component 1 and the driven component 2 include a base plate 11 and a push rod 12 arranged in parallel. Side guard plates 14 are rotatably mounted on both ends of the push rod 12. Two symmetrically arranged lower rotating rods 16 are rotatably mounted on the upper surface of the base plate 11, and two symmetrically arranged upper rotating rods 15 are rotatably mounted on the lower surface of the push rod 12. A rotating rod joint 17 is rotatably mounted between the upper rotating rods 15 and the lower rotating rods 16. A side guard rod 18 is rotatably mounted on the lower surface of the side guard plate 14. The lower end of the side guard rod 18 is rotatably mounted in the middle of the lower rotating rod 16. The two base plates 11, the two push rods 12, and the two side guard plates 14 are all connected by connecting rods 3. The hydraulic drive component 1 also includes a hydraulic cylinder 13 for lifting and lowering arranged between the base plate 11 and the push rod 12.
[0021] In this embodiment, at least one driven member 2 is provided, and the hydraulic drive member 1 and the driven member 2 are connected by a connecting rod 3. This facilitates the lifting of the belt by the hydraulic drive member 1, with the driven member 2 following the lifting of the hydraulic drive member 1. This increases the balance of the hydraulic drive member 1 during lifting and increases the contact area during belt lifting. Both the hydraulic drive member 1 and the driven member 2 are composed of a base plate 11, a push rod 12, a side guard plate 14, an upper rotating rod 15, a lower rotating rod 16, a rotating rod joint 17, and a side guard rod 18. The hydraulic drive member 1 is also equipped with a hydraulic cylinder 13 for lifting, which facilitates the lifting of the hydraulic drive member 1 by the hydraulic cylinder 13 along with the push rod 12. The base plate 11, two top rods 12, and two side guard plates 14 are all connected by connecting rods 3, so that the hydraulic drive component 1 can lift and lower the driven component 2, and the top rod 12 can lift the belt. The base plate 11 and the top rod 12 are connected by an upper rotating rod 15, a lower rotating rod 16, and a rotating rod joint 17, so that the top rod 12 can maintain the balance at both ends when it is lifted and lowered. The side guard rod 18 is rotatably installed between the lower rotating rod 16 and the side guard plate 14, so that when the lower rotating rod 16 rotates, the side guard plate 14 rotates through the side guard rod 18. Thus, when the top rod 12 is lifted and lowered, the side guard plate 14 is turned towards the top rod 12 under the action of the side guard rod 18, so that the "V" shaped belt can be better supported by the top rod 12 and the side guard plate 14, which makes it easier to replace the idler roller after the belt is raised.
[0022] The connecting holes 4 are provided on the base plate 11, the top rod 12 and the side guard plate 14, and the connecting holes 4 provided on the hydraulic drive component 1 and the driven component 2 correspond one-to-one. This facilitates the connection of the two base plates 11 of the hydraulic drive component 1 and the driven component 2 through the connecting rods 3 installed in the connecting holes 4, and also facilitates the connection of the two top rods 12 and the two side guard plates 14 through the connecting rods 3 installed in the connecting holes 4.
[0023] The upper rotating rod 15 and the lower rotating rod 16 are of equal length. The rotating rod joint 17 is vertically arranged between the base plate 11 and the top rod 12, so that the top rod 12 remains balanced when it rises and falls above the base plate 11. The side guard plate 14, the upper rotating rod 15, the lower rotating rod 16, and the side guard rod 18 form a quadrilateral, which facilitates the rotation of the lower rotating rod 16 by rotating the side guard plate 14 through the side guard rod 18. The base plate 11 has end plates integrally formed at both ends, which are twice the width of its middle section, increasing the area at both ends of the base plate 11.
[0024] In use, take out an appropriate number of driven parts 2 as needed and place them on the side of the hydraulic drive 1. Put the hydraulic drive 1 and driven parts 2 into the belt frame and insert the connecting rod 3 into the connecting hole 4 to connect the hydraulic drive 1 and driven parts 2. When the hydraulic cylinder 13 works, the telescopic end carries the push rod 12 of the hydraulic drive 1 to rise. After the push rod 12 is connected by the connecting rod 3, the push rod 12 of the hydraulic drive 1 and driven parts 2 cooperate to lift the belt. When the push rod 12 rises, the push rod 12 carries the upper rotating rod 15 to rotate. The upper rotating rod 15 carries the lower rotating rod 16 to rotate through the rotating rod joint 17. When the lower rotating rod 16 rotates, it carries the side guard plate 14 to rotate through the side guard rod 18. The side guard plate 14 rotates upward and approaches the push rod 12, so that the belt is lifted by the cooperation of the push rod 12 and the side guard plate 14.
