Description

Technical Field

[0001] This utility model relates to the field of underground mining technology, specifically a rapid concrete conveying device suitable for underground filling and return concrete in mines. Background Technology

[0002] In underground mines, the management of excess mortar generated during backfilling has a significant impact on safety and economic costs. During backfilling, the area to be filled is usually enclosed, making it difficult for personnel to monitor the backfilling effect. However, to ensure a successful roof connection, backfill return holes are typically left at the top of the backfill wall. The outflow of mortar from these return holes is used as a marker of successful backfilling. However, when a large amount of mortar flows out of these return holes, it leads to several problems: significant mortar waste, increasing backfilling costs; the need to transfer excess mortar to a storage silo and then transport it to the surface by truck, increasing transportation costs; and the potential for blockage if excess mortar is not properly cleaned and is shoveled into the ore pass. Therefore, a rapid concrete sluice device suitable for backfilling in underground mines is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a rapid concrete conveying device suitable for underground filling and return concrete in mines, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rapid concrete conveying device suitable for backfilling concrete in underground mines, comprising a support rod, a slotted device welded to the support rod, a U-shaped stabilizer fixedly installed on the slotted device, auxiliary stabilizing rods fixedly installed on both sides and bottom of the U-shaped stabilizer, an S-shaped hanger provided on the support rod, and concrete conveying surface stabilization points provided on the support rod, with concrete conveying surface fixedly installed on the concrete conveying surface stabilization points.

[0005] As a further improvement of this utility model, the support rods are two cylinders, wherein the cylinders have good load-bearing capacity and bending flexibility.

[0006] As a further improvement of this utility model: wherein the bends on both sides of the U-shaped stabilizer are fixedly installed on the support rod, and the support rod is connected.

[0007] As a further improvement of this utility model, the U-shaped stabilizer is provided with auxiliary stabilizing rods welded to its sides and bottom, and the auxiliary stabilizing rods are cylindrical.

[0008] As a further embodiment of this utility model: wherein the slot is a welding point uniformly welded on the surface of the support rod, not exceeding the cross-section of the cylindrical support rod.

[0009] As a further embodiment of this utility model: wherein the type of suspension device is an S-shaped hook evenly distributed on the support rod, and the height of the S-shaped suspension device is different.

[0010] As a further embodiment of this utility model: wherein the concrete lining sheet is a leak-proof concrete waterproof cloth, and the concrete lining sheet is laid on the surface of the skeleton part.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] After the support rod is connected by the U-shaped stabilizer fixed by the slot on the support rod, the auxiliary stabilizer is fixedly installed on the U-shaped hanger to reinforce and support the U-shaped hanger. At the same time, the concrete slurry surface is fixedly connected to the stabilizing point of the support rod. The concrete slurry surface is laid on the overall frame. The support rod is lifted by the S-shaped hangers at different heights to form a slope, so that the mortar flows with the slope. This avoids the waste of mortar, the increased cost of transferring excess mortar, and the risk of shoveling it into the ore pass, which can easily lead to blockage of the ore pass.

[0018] refer to Figure 1 , Figure 1 The diagram shows the structure of support rod 1. Support rod 1 is a set of cylinders, and evenly distributed slots 2 are fixedly installed on support rod 1. The slots 2 are welded points on the surface of support rod 1 and do not exceed the cross-section of support rod 1. Figure 1 Figure 2 As shown, a U-shaped stabilizer 3 is fixedly installed on the slot 2. The two ends of the U-shaped stabilizer 3 are arc-shaped and opposite to their opening directions. A set of support rods 1 are fixedly connected via the U-shaped stabilizer 3. Auxiliary stabilizing rods 4 are fixedly installed at the bottom of the curved sides of the U-shaped stabilizer 3. The auxiliary stabilizing rods 4 are three cylinders used to reinforce the U-shaped stabilizer 3, ensuring uniform flow of the concrete and bearing the weight of the concrete. Figure 3As shown, an S-shaped hanger 6 is installed on the support rod 1. The bottom hook of the S-shaped hanger 6 is fixedly connected to the support rod 1, and the upper hook is connected to the site. The S-shaped hanger 6 lifts the support rod 1 and forms an integral frame with the above components (note the length of the S-shaped hanger 6 so that the overall frame forms an angled inclined slope to ensure that the material can slide).

[0019] like Figure 1 As shown, the support rod 1 has uniformly and symmetrically distributed concrete slurry stabilization points 5, which are holes. The support rod 1, U-shaped stabilizer 3 and auxiliary stabilizing rod 4 are covered with fixed concrete slurry sheets 7, which are waterproof concrete slurry sheets and are fixed to the concrete slurry stabilization points 5 at both ends. The concrete slurry sheets 7 are laid on the surface of the frame part to form a channel for rapid concrete slurry.

[0020] Working principle: A U-shaped stabilizer 3 is fixedly installed on the support rod 1 through the slot 2, and the U-shaped stabilizer 3 fixes a pair of support rods 1 together. At the same time, an auxiliary stabilizing rod 4 is fixedly installed on the U-shaped stabilizer 3. An S-shaped hanger 6 is fixedly connected to the support rod 1. One end of the S-shaped hanger 6 is fixedly installed to the support rod 1, and the other end is connected to the site, forming a frame. Concrete slab stabilization points 5 are opened on the support rod 1. Concrete slabs 7 are laid on the frame. The two ends of the concrete slabs 7 are fixed to the concrete slab stabilization points 5. By using the different lengths of the S-shaped hangers 6, the overall frame forms an inclined angle. When mortar is placed on the concrete slabs 7, it slides according to the inclined angle.
