Description

Technical Field

[0001] This utility model relates to the field of mine roadway technology, specifically to a roadway anti-collapse support device. Background Technology

[0002] Due to the large scale and high intensity of mining operations, as well as the increasing depth of operations, roof falls are prone to occur in the working roadways, especially at the ends of the working face, where large-scale roof collapses are very likely to occur. This not only hinders production but also endangers the lives of the workers.

[0003] Existing support devices have fixed top support plates, which requires denser support devices. However, too many support devices result in the bottom support rods taking up more space, making it inconvenient for workers to work. Furthermore, the support devices are difficult to move, requiring multiple workers to push them, which is very troublesome. Therefore, we propose a tunnel anti-collapse support device. Utility Model Content

[0004] In view of the problems existing in the above-mentioned roadway anti-collapse support devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a tunnel anti-collapse support device, which solves the problem that the bottom support rod occupies more space when there are too many support devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tunnel anti-collapse support device includes a base plate, a fixing rod threaded on the top of the base plate, a fixing groove fixed on the bottom of the base plate, a connecting plate in the fixing groove, one end of the fixing rod being rotatably connected to the connecting plate, a plurality of traveling wheels fixed on the bottom of the connecting plate, a support rod fixed on the top of the base plate, a fixing plate fixed on the top of the support rod, first slide rails fixed on both sides of the fixing plate, two first sliding plates slidingly disposed within the first slide rails, sliding plates fixed on the top of the two first sliding plates, and two fixing devices fixed on both side walls of the first slide rails.

[0008] Preferably, the fixing device includes a rod and a slot. A slot is fixedly opened on one side wall of the first slide plate, and a spring is fixedly provided on one side of the first slide rail. The rod is sleeved inside the spring, and the rod is inserted into the slot.

[0009] Preferably, a second slide rail is fixedly provided on the top of the fixed plate, and a second slide plate is fixedly provided on the bottom of the sliding plate, with the second slide rail and the second slide plate slidingly engaged.

[0010] Preferably, two telescopic rods are rotatably provided on both sides of the fixed plate, and one end of the two telescopic rods is rotatably connected to the sliding plate.

[0011] Furthermore, a support column is fixedly provided on the inner side wall of the fixed plate, and multiple load-bearing columns are fixedly provided on both sides of the support column.

[0012] Preferably, both the fixed plate and the sliding plate are made of stainless steel.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This invention utilizes a combination of sliding plates and fixed plates to allow the top of the support device to support a larger area. To prevent existing support devices from having fixed top support plates during operation, which would require more dense support, two sliding plates are used to slide on the fixed plates. This solves the problem of the bottom support rods occupying more space when there are too many support devices, making it more convenient for workers to work. Furthermore, to prevent the support device from being difficult to move and to avoid requiring multiple workers to push the device, the bottom wheels are designed to be retractable. When not in use, they can be stored in the fixed slots, ensuring the stability of the device and making it very convenient. Attached Figure Description
