Technical Field

[0001] This utility model relates to the field of pin assembly and disassembly technology, and in particular to a device for assembling and disassembling large pins in a scraper drive chain. Background Art

[0002] Scraper chain conveyors are used for transportation in the calcination workshop. These conveyors operate at full load with no backup. Under these conditions, if one scraper chain plate breaks, the length of repair time will affect production output. Previously, maintenance personnel had to use a sledgehammer to remove the large pins when disassembling the chain plates and pins, posing a significant safety risk. Furthermore, the limited maintenance space on the scraper chain conveyor hinders multi-person coordination, increasing the difficulty and safety risks. Therefore, a device for installing and removing large pins from the scraper drive chain is proposed. Summary of the Invention

[0004] Technical solution: To achieve the above objectives, this utility model provides a device for mounting and dismounting a large pin in a scraper drive chain, comprising a cylinder, a telescopic body inside the cylinder, one end of which extends out of the cylinder to form a pusher for the large pin; a hook arm is mounted on the cylinder, and a hook plate is provided at the end of the hook arm away from the cylinder, with the hook plate and the pusher spaced apart; a slot is provided on the hook plate, and the slot is opposite to the pusher.

[0005] Furthermore, the hook arm is mounted on the cylinder via a movable seat, which can be adjusted on the cylinder to change the distance between the hook plate and the cylinder.

[0006] Furthermore, the movable seat is provided with a screw hole, and the outer wall of the cylinder is provided with an external thread structure. The cylinder is inserted into the screw hole and is threadedly engaged with the screw hole. The cylinder can rotate within the screw hole to change the distance between the hook plate and the cylinder.

[0007] Furthermore, a handle is installed on the movable seat, and the handle and hook arm are respectively connected to opposite sides of the movable seat.

[0008] Furthermore, the extension and retraction direction of the top head is perpendicular to the hook plate.

[0009] Furthermore, the side of the slot away from the hook arm extends to the edge of the hook plate to form a groove.

[0010] Furthermore, the cylinder is a hydraulic puller.

[0011] Furthermore, the cylinder is a hydraulic telescopic cylinder.

[0012] Beneficial effects: The scraper drive chain large pin installation and removal device of this utility model uses a hook plate with a slot to hook the scraper drive chain, and then aligns the mandrel with the large pin and pushes the large pin, thereby realizing the removal or installation of the large pin, reducing the labor intensity of operators and improving production efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] As attached Figures 1 to 4 The aforementioned device for mounting and dismounting large pins in a scraper drive chain includes a cylinder 1, inside which is a telescopic body that can extend and retract along the length of the cylinder 1. One end of the telescopic body can extend out of the cylinder 1 to form a push head 3, which is used to push the large pins 2 on the scraper drive chain.

[0019] A hook arm 4 is installed on the cylinder 1, extending vertically along the length of the cylinder 1. One end of the hook arm 4 is connected to the cylinder 1, and a hook plate 5 is provided at the end of the hook arm 4 away from the cylinder 1. The hook plate 5 is opposite to the top head 3, and the hook plate 5 and the top head 3 are spaced apart. A slot 6 is provided on the hook plate 5, and the slot 6 is opposite to the top head 3. The structure of the scraper drive chain is shown in the attached figure. Figure 4 As shown, there is a sleeve 9 outside the large pin 2. When the hook plate 5 is hooked on the scraper drive chain, the sleeve 9 enters into the slot 6, and the hook plate 5 is hooked on the chain plate 10. Then, the top head 3 is aligned with the large pin 2 and the top head 3 is pushed forward, which can realize the removal or installation of the top head 3.

[0020] The hook arm 4 is mounted on the cylinder 1 via a movable seat 7. The movable seat 7 can be adjusted on the cylinder 1 to change the distance between the hook plate 5 and the cylinder 1. When the hook plate 5 is hooked on the scraper drive chain, the relative position of the cylinder 1 and the hook plate 5 can be adjusted to bring the top head 3 closer to the large pin 2.

[0021] As attached Figure 1In one embodiment shown, a screw hole is provided on the movable seat 7, and an external thread structure is provided on the outer wall of the cylinder 1. The cylinder 1 is inserted into the screw hole, and the cylinder 1 is threadedly engaged with the screw hole. The cylinder 1 can rotate within the screw hole of the movable seat 7, thereby changing the distance between the hook plate 5 and the cylinder 1.

[0022] A handle 8 is installed on the movable seat 7. The handle 8 and the hook arm 4 are respectively connected to opposite sides of the movable seat 7. The handle 8 allows workers to easily hold the device for assembly and disassembly. In addition, when adjusting the distance between the hook plate 5 and the cylinder 1, the worker can grasp the movable seat 7 through the handle 8 and then rotate the cylinder 1 for easy operation.

[0023] The extension and retraction direction of the top head 3 is perpendicular to the hook plate 5, so that the hook plate 5 can hook more stably on the scraper drive chain.

[0024] The slot 6 extends from the side away from the hook arm 4 to the edge of the hook plate 5, forming a groove, which makes it easier for the sleeve 9 on the scraper drive chain to enter the slot 6.

[0025] In one embodiment, the cylinder 1 is a hydraulic puller, which drives the top head 3 to extend and retract.

[0026] In one embodiment, the cylinder 1 is a hydraulic telescopic cylinder, which drives the top head 3 to extend and retract.

[0027] Taking the cylinder 1 as an example of a hydraulic puller, the working method of this utility model is explained as follows: When it is necessary to remove the large pin 2, first use a chain hoist to fix the scraper drive chain, then remove the small pin 11 on the large pin 2, then let the sleeve 9 enter the slot 6 of the hook plate 5, and let the hook plate 5 hook onto the chain plate 10. Then, the worker holds the movable seat 7 by the handle 8 and rotates the puller so that the top head 3 of the puller head is aligned with the large pin 2. Then, press the puller to make the top head 3 extend forward and push the large pin 2 out of the sleeve 9, thus removing the large pin 2. When it is necessary to install the large pin 2, the large pin 2 is pushed into the sleeve 9.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
