Description

Technical Field

[0001] This invention belongs to the field of coal mine sealed wall construction technology, specifically relating to a brick grabbing and mortar application device for sealed wall construction operations. Background Technology

[0002] The construction of sealed walls in coal mines is a crucial aspect of safe production, serving purposes such as isolating goaf areas, fire prevention, and preventing gas accumulation. Currently, the construction of sealed walls is largely done manually, requiring workers to manually move bricks, apply mortar, and lay the walls layer by layer. This method is labor-intensive, inefficient, and the working environment typically contains hazardous factors such as gas and dust, posing a threat to personnel safety.

[0003] In recent years, to improve operational efficiency and reduce manual risks, some mechanized bricklaying equipment has been put into use, such as using robotic arms for brick grabbing and placement. However, existing devices are relatively simple in function, typically only capable of grabbing and transporting bricks, unable to simultaneously complete mortar application, thus still requiring manual intervention for mortar application, which restricts the improvement of overall construction efficiency. Furthermore, existing equipment is prone to leakage and contamination of the grabbing components during mortar delivery and application, affecting the normal operation of the device and the quality of the wall construction. Therefore, it is necessary to develop an automated device that integrates brick grabbing and mortar application functions, with a reasonable structure and convenient operation, to achieve high efficiency, safety, and standardization in coal mine sealed wall construction operations. Summary of the Invention

[0004] This invention addresses the problem that existing bricklaying devices can only grasp and transport bricks, but cannot simultaneously apply mortar.

[0005] The present invention provides the following technical solution: a brick grabbing and mortar application device for sealed wall masonry operations, comprising a support frame, the support frame including a connecting part for connection with a working robotic arm and a main body part arranged with a suction cup device and a mortar channel; the outlet of the mortar channel and the adsorption surface of the suction cup device face the same direction; the adsorption surface of the suction cup device can grab bricks by negative pressure; a sealing door is provided at the outlet of the mortar channel; the sealing door closes the outlet of the mortar channel when the suction cup device grabs bricks, and opens when mortar is discharged from the mortar channel.

[0006] Furthermore, the main body of the support frame includes an "I"-shaped intermediate frame, with a suction cup device embedded in the lower groove of the intermediate frame; the interior of the two side uprights of the intermediate frame is hollow, forming mortar channels; the mortar channels on both sides are each connected to a lateral mortar pipe, which is located in the upper groove of the intermediate frame; the lateral mortar pipe is connected to the mortar pumping equipment through a mortar delivery hose.

[0007] Furthermore, the sealing door includes a flip-up baffle hinged to the bottom of the upright plate of the intermediate frame. A pressure bar is connected to the flip-up baffle. When there is no mortar discharge at the mortar channel outlet, the pressure bar can pry the flip-up baffle to close the outlet by its own weight.

[0008] Furthermore, a shotcrete pipe is provided at one end of the intermediate frame facing away from the support frame. The shotcrete pipe protrudes outward relative to the intermediate frame and is connected to the intermediate mortar pipe, which is located in the upper groove of the intermediate frame. The intermediate mortar pipe is connected to the mortar pumping equipment through a mortar conveying hose.

[0009] Furthermore, a scraper is installed on the intermediate frame, with one end of the scraper connected to the intermediate frame and the other end extending above the intermediate mortar pipe and protruding relative to the intermediate mortar pipe.

[0010] Furthermore, the connecting part of the support frame includes two parallel connecting rods.

[0011] Furthermore, two pressure rods are connected to the flip baffle, and the two pressure rods are located on both sides of the suction cup device.

[0012] Furthermore, two ribs are provided in the upper groove of the intermediate frame, and two connecting rods are connected to the two ribs respectively.

[0013] Compared with the prior art, the advantages of the present invention are: This invention provides a brick-grabbing and mortar-applying device for closed-loop wall construction, integrating brick-grabbing and mortar-applying functions. It uses a suction cup device to achieve negative pressure gripping and placement of bricks, while simultaneously applying mortar through a mortar channel. This design effectively solves the problem of requiring separate steps for brick handling and mortar application in traditional operations, significantly improving the overall efficiency of wall construction.

[0014] The device employs an "I"-shaped intermediate frame structure, with the suction cup device embedded in the lower groove. The mortar channels are integrated within the side uprights, while the lateral and central mortar pipes are arranged in the upper groove. The overall structure is compact and space-efficient, facilitating connection with a robotic arm and enabling stable operation. A flip-up baffle with a pressure rod at the mortar channel outlet automatically closes when there is no mortar and automatically opens when mortar is present. This design effectively prevents mortar leakage during non-coating stages, avoiding contamination of the suction cup device and the working environment, and ensuring the reliability and cleanliness of the device's operation.

[0015] Once the wall construction is complete, the spray pipe can spray mortar onto the vertical surface of the wall. The scraper on the intermediate frame can smooth the mortar after spraying, ensuring that the mortar layer is uniform and flat, which helps to improve the quality and appearance consistency of the wall construction.

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown: A brick-grabbing and mortar-applying device for closed-wall masonry operations includes a support frame 1. The support frame 1 includes a connecting part for connection with a robotic arm and a main body with a suction cup device 2 and a mortar channel 3. The outlet of the mortar channel 3 and the adsorption surface of the suction cup device 2 face the same direction. The adsorption surface of the suction cup device 2 can grab bricks through negative pressure. A sealing door is provided at the outlet of the mortar channel 3. The sealing door closes the outlet of the mortar channel 3 when the suction cup device 2 grabs bricks to prevent mortar from flowing out of the mortar channel 3 and contaminating the suction cup device 2. The sealing door opens when mortar is discharged from the mortar channel 3.

[0020] The main body of the support frame 1 includes an "I"-shaped intermediate frame 1.1, which isolates the working side and the pipeline side. The suction cup device 2 is embedded in the lower groove of the intermediate frame 1.1. The interior of the two side uprights of the intermediate frame 1.1 is hollow, forming mortar channels 3, and the top of the uprights is closed. The mortar channels 3 on both sides are connected to lateral mortar pipes 4, which are located in the upper groove of the intermediate frame 1.1. The lateral mortar pipes 4 are connected to the mortar pumping equipment through mortar delivery hoses. The mortar pumping equipment delivers mortar to the lateral mortar pipes 4 through the mortar delivery hoses. The mortar is applied to the wall through the mortar channels 3 formed in the uprights of the intermediate frame 1.1. When applying mortar, a gap is left between the outlet of the mortar channel 3 and the mortar application surface, i.e., a gap is left between the suction cup device 2 and the mortar application surface. The mortar flowing out of the mortar channel 3 falls onto the wall, preventing the mortar from sticking to the suction cup device 2.

[0021] The sealing door includes a flip-up baffle 5 hinged to the bottom of the upright plate of the intermediate frame 1.1. A pressure rod 6 is connected to the flip-up baffle 5. The pressure rod 6 can pry the flip-up baffle 5 shut off the outlet of the mortar channel 3 by its own weight when no mortar is discharged. Two pressure rods 6 are connected to the flip-up baffle 5, located on both sides of the suction cup device 2. The flip-up baffle 5 opens towards the suction cup device 2. After opening, the flip-up baffle 5 acts as a partition between the outlet of the mortar channel 3 and the suction cup device 2, preventing mortar flowing out of the mortar channel 3 from splashing onto the suction cup device 2.

[0022] A shotcrete pipe 7 is installed at one end of the intermediate frame 1.1 facing away from the support frame 1. The shotcrete pipe 7 protrudes outward relative to the intermediate frame 1.1 and is connected to the intermediate mortar pipe 9, which is located in the upper groove of the intermediate frame 1.1. The intermediate mortar pipe 9 is connected to the mortar pumping equipment through a mortar conveying hose. The shotcrete pipe 7 and the mortar channel 3 use independent mortar conveying pipelines to meet the requirements of independent operation. A scraper 8 is installed on the intermediate frame 1.1. One end of the scraper 8 is connected to the intermediate frame 1.1, and the other end extends above the intermediate mortar pipe 9, protruding relative to the intermediate mortar pipe 9.

[0023] The connecting part of the support frame 1 includes two parallel connecting rods 1.2. Two ribs 1.3 are provided in the upper groove of the intermediate frame 1.1, and the two connecting rods 1.2 are respectively connected to the two ribs 1.3 to increase the connection strength between the connecting rods 1.2 and the intermediate frame 1.1.

[0024] During bricklaying, the robotic arm moves the brick-grabbing and mortar-applying device for the sealed wall. The device first applies a layer of mortar through mortar channel 3. The pressure of the mortar during application pushes open the tilting baffle 5, allowing the mortar to flow smoothly. After one layer of mortar is applied, the mortar pump stops supplying mortar to the lateral mortar pipe 4. With no mortar pressure at the outlet of mortar channel 3, the pressure rod 6 uses its own weight to pry open the tilting baffle 5 and close the outlet. The brick-grabbing and mortar-applying device then uses suction cup device 2 to pick up bricks, which are then placed flat on the mortar. After one layer of bricks is placed, mortar is sprayed again, and this cycle is repeated to complete the construction of the entire wall. After the wall is completed, mortar is sprayed onto the outer wall surface through spray pipe 7, and then smoothed with scraper 8.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
