Description

Technical field

[0001] The utility model belongs to the technical field of maintenance of underground scraper conveyors, and particularly relates to a lifting auxiliary tool for a trough plate of an underground scraper conveyor. [Background Technology]

[0002] A scraper conveyor is a device used to transport coal and other materials, and is widely used in coal mines, chemical mines, metal mines, power plants, and other locations. It primarily consists of a central trough, chain, scrapers, and a traction system. The scraper chain circulates within a closed rectangular housing, moving material along the chute to the conveyor head for unloading.

[0003] A scraper conveyor primarily consists of three sections: the nose, middle section, and tail section. The middle section, comprised of the trough, chain, and scrapers, is the primary load-bearing and conveying component. During underground maintenance of scraper conveyors, the trough often sinks, requiring lifting and leveling. However, currently, no suitable tool exists for lifting and securing the trough. [Utility Model Content]

[0004] The utility model aims to provide a lifting auxiliary tool for a trough plate of an underground scraper conveyor, so as to solve the problem that there is no suitable auxiliary tool for lifting and fixing the trough plate in the prior art.

[0005] The utility model adopts the following technical solution: an auxiliary tool for lifting the trough plate of an underground scraper conveyor, comprising a connecting rod, both ends of which are respectively connected to a T-shaped clamping piece, and a clamping ring is provided on the rod body of the connecting rod;

[0006] It also includes a lifting device, wherein the lifting end of the lifting device has a steel wire rope, and the end of the steel wire rope is connected to a hook;

[0007] Among them, the connecting rod is used to be placed in the slot plate to be repaired, the two T-shaped clamping parts are used to be placed in the U-shaped groove of the slot plate, the hook is used to be clamped on the clamping ring, and the lifting device is used to lift the connecting rod to lift the slot plate to be repaired.

[0008] Furthermore, there are two symmetrically arranged T-shaped clips, and two steel ropes are symmetrically arranged at the lifting end of the lifting device.

[0009] Furthermore, the T-shaped clamping piece is a horseshoe ring.

[0010] The beneficial effect of the utility model is that by using the lifting auxiliary tool, the trough plate can be conveniently lifted when the scraper conveyor is being repaired underground, making it easier to level or lift the trough plate and to deal with the problem of floating chain failure caused by the trough plate sinking. The lifting auxiliary tool has a simple structure and is easy to use, which improves the maintenance efficiency and ensures safety during the maintenance period.

[0012] Figure 2 This is a structural schematic diagram of a scraper conveyor maintenance auxiliary tool of the utility model when it is stuck in the trough plate.

[0013] Among them, 1. connecting rod, 2. T-shaped clamping piece, 3. clamping ring, 4. wire rope, 5. hook, 6. groove plate, 7. U-shaped groove, 8. lifting device. [Specific implementation method]

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] The utility model provides a scraper conveyor maintenance auxiliary tool, such as Figure 1 and Figure 2 As shown, it includes a connecting rod 1, each end of which is connected to a T-shaped clamping piece 2, and a clamping ring 3 is provided on the rod body of the connecting rod 1; it also includes a lifting device 8, the lifting end of the lifting device 8 has a wire rope 4, and the end of the wire rope 4 is connected to a hook 5.

[0016] Among them, the connecting rod 1 is used to be placed in the slot plate 6 to be repaired, the two T-shaped clamping parts 2 are used to be placed in the U-shaped slot 7 of the slot plate, the hook 5 is used to be clamped on the clamping ring 3, and the lifting device 8 is used to lift the connecting rod 1 to lift the slot plate 6 to be repaired.

[0017] In actual use, multiple sizes of T-shaped clips 2 are pre-processed in advance. During use, the T-shaped clips 2 of corresponding sizes can be selected according to the height of the U-shaped slot 7 in the slot plate 6. For example, the widest dimension of the T-shaped clip 2 is slightly smaller than the height of the U-shaped slot 7, so as to ensure that when the T-shaped clip 2 is perpendicular to the axis of the slot plate 6, it can be stuck in the U-shaped slot 7 and is not easy to fall off.

[0018] In some embodiments, there are two symmetrically arranged T-shaped clips 2, and two steel wire ropes 4 are symmetrically arranged at the lifting end of the lifting device 8. When there are two, the lifting process is more stable.

[0019] In some embodiments, the T-shaped clamping member 2 is a horseshoe ring. A horseshoe ring is a T-shaped structural member that can be used as the T-shaped clamping member 2 here.

[0020] The utility model discloses a method for using a lifting auxiliary tool for a trough plate of an underground scraper conveyor:

[0021] like Figure 1 As shown, the connecting rod 1 is placed in the slot plate 6, and the two T-shaped clips 2 are placed in the two U-shaped slots 7. At this time, the T-shaped clips 2 are parallel to the axis direction of the slot plate 6;

[0022] like Figure 2 As shown, the connecting rod 1 is rotated so that the T-shaped clamping member 2 is perpendicular to the axis direction of the slot plate 6 and is clamped in the U-shaped slot 7;

[0023] Connect the steel wire rope 4 of the lifting device 8 to the clamping ring 3 through the hook 5, and operate the lifting device 8 to lift the connecting rod 1, thereby lifting the groove plate 6.

[0024] In actual use, two lifting auxiliary tools of a kind of underground scraper conveyor trough plate of the present invention can be installed on a single trough plate 6, so that lifting is more stable. After lifting, the trough plate can be leveled or replaced.

[0025] This lifting aid tool allows for convenient lifting of the trough plate during underground maintenance of the scraper conveyor, facilitating leveling or lifting of the trough plate, and addressing issues with floating chain failures caused by trough plate sinking. This lifting aid tool has a simple structure and is easy to use, improving maintenance efficiency and ensuring safety during maintenance.
