Description

Technical Field

[0001] The utility model relates to the technical field of pipe column production, in particular to an integrated device for belt tensioning and material recovery. Background Art

[0002] The pipe column production process includes the existing concrete pipe pile production process, which is divided into reinforcement cutting, cage weaving, assembly, concrete pouring, tensioning, centrifugal, steam curing, and autoclaving. In the concrete pouring stage, cement, sand, gravel, stone, admixtures, water, admixtures and other materials are stored in their respective hoppers and transported to the mixer by an inclined belt conveyor in a certain proportion. The raw materials are fully mixed before proceeding to the subsequent production stages.

[0003] After the belt conveyor has been used for a long time, the belt has the problem of insufficient tension, which seriously affects the transportation of materials and causes the belt to fall due to belt shaking during loading. Due to the limited installation space in the factory, it is not easy to set a tensioning structure on the driven roller side of the inclined belt. Setting a tensioning belt in the middle requires manual adjustment, but it is difficult to control the tension of the belt manually, which easily leads to insufficient tension of the synchronous belt.

[0004] The utility model aims to provide an integrated device for belt tensioning and material recovery.

[0005] The utility model is implemented by the following technical scheme: an integrated device for belt tensioning and material recovery, which includes a belt conveyor, a tensioning device, a support frame, and a recovery device;

[0006] A material receiving plate is fixed at the bottom of the frame of the belt conveyor, and the material receiving plate is consistent with the conveying direction of the belt conveyor. The bottom end of the belt conveyor is provided with the tensioning device, the support frame and the recovery device in sequence along its conveying direction. The support frame is rotatably connected to the bottom end frame of the belt conveyor, and the tensioning device is slidably provided on one side of the support frame;

[0007] The tensioning device comprises a load-bearing frame, a tensioning roller, a first guide roller, and a second guide roller, the load-bearing frame is slidably connected to the slide groove of the support frame, the load-bearing frame is rotatably connected to the tensioning roller on a side away from the support frame, the frame of the belt conveyor is rotatably connected to the first guide roller and the second guide roller, the tensioning roller is arranged between the first guide roller and the second guide roller, the descending belt of the belt conveyor is sequentially wound around the first guide roller, the tensioning roller, and the second guide roller, and the material receiving plate is provided with a guide port for the descending belt of the belt conveyor to pass through;

[0008] The recovery device is fixed on the side of the support frame away from the tensioning device. The recovery device includes a hopper and a discharge pipe. The inlet of the hopper is fixedly connected to the receiving plate and communicated with the interior of the belt conveyor. The receiving plate is provided with a through groove matching the inlet of the hopper.

[0009] Furthermore, a telescopic hose is connected between the feed pipe and the hopper.

[0010] Furthermore, a tilted screen is fixed at the bottom of the feed pipe, a block material outlet is fixed on the outer wall of the feed pipe at the bottom of the screen, and the block material outlet is connected to a block material collection box through a pipeline.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, the integrated device for belt tensioning and material recovery includes a belt conveyor 1, a tensioning device 3, a support frame 4, and a recovery device 5;

[0020] A receiving plate 2 is fixed at the bottom of the frame of the belt conveyor 1, and the receiving plate 2 is consistent with the conveying direction of the belt conveyor 1. In daily production, the function of the receiving plate 2 is to intercept the materials falling from the belt conveyor 1 to prevent pedestrians under the belt conveyor 1 from being injured, and to guide the materials on the belt conveyor 1 downward along the receiving plate 2 to the receiving end of the belt conveyor 1. Since the frame of the belt conveyor 1 is not in a closed state, the materials can fall directly from the belt conveyor 1 to the designated area, which is convenient for the recovery of the fallen materials.

[0021] The bottom end of the belt conveyor 1 is provided with a tensioning device 3, a support frame 4 and a recovery device 5 in sequence along its conveying direction. The support frame 4 is rotatably connected to the bottom end frame of the belt conveyor 1. The support frame 4 can adjust the vertical state of the support frame 4 according to the inclination angle of the belt conveyor 1. The tensioning device 3 is slidably provided on one side of the support frame 4. The counterweight on the tensioning device 3 is adjusted according to the amount of recovered material in the recovery device 5.

[0022] The tensioning device 3 includes a load-bearing frame 3.1 and a tensioning roller 3.2. The load-bearing frame 3.1 is slidably connected to a slide groove 3.3 of a support frame 4. The load-bearing frame 3.1 is rotatably connected to a tensioning roller 3.2 on a side away from the support frame 4. The frame of the belt conveyor 1 is rotatably connected to a first guide roller 3.4 and a second guide roller 3.5. The tensioning roller 3.2 is placed between the first guide roller 3.4 and the second guide roller 3.5. The downward belt of the belt conveyor 1 is sequentially wound around the first guide roller 3.4, the tensioning roller 3.2, the second guide roller 3.5, and the tensioning roller 3.2 is placed between the first guide roller 3.4 and the second guide roller 3.5. Between the rollers 3.5, a guide opening 3.6 for the downward belt of the belt conveyor 1 to pass through is provided on the material receiving plate 2. The belt can be tensioned by means of the tensioning device 3. According to the tensioning condition of the belt, a corresponding counterweight is placed in the load-bearing frame 3.1, thereby reducing the problem of material leakage due to belt loosening. The tensioning device 3 is arranged in the middle of the belt conveyor 1 to solve the problem of insufficient space in the factory area. Since the belt conveyor 1 is tilted upward for transportation, the space below the belt conveyor 1 is large enough to accommodate the tensioning device 3 and the recovery device 5 in the middle.

[0023] A recovery device 5 is fixed on the side of the support frame 4 away from the tensioning device 3. The recovery device 5 includes a hopper 5.1 and a discharge pipe 5.2. The inlet of the hopper 5.1 is fixedly connected to the receiving plate 2 and is communicated with the interior of the belt conveyor 1. The receiving plate 2 is provided with a through groove 5.3 matching the inlet of the hopper 5.1. The function of the recovery device 5 is that once the belt becomes loose during the production process, before the operator adjusts the tensioning device 3, the material dropped from the belt conveyor 1 can be recovered into the recovery device 5. Since the tensioning device 3 is arranged in the middle of the belt conveyor 1, the recovery device 5 can intercept the material dropped from the belt conveyor 1 above the tensioning device 3 to reduce the damage to the tensioning device 3.

[0024] A telescopic hose 5.4 is connected between the feeding pipe 5.2 and the hopper 5.1. The function of the telescopic hose 5.4 is to cooperate with the rotation of the support frame 4 when adjusting the inclination angle of the belt conveyor 1 so that the feeding pipe 5.2 is in a vertical state.

[0025] An inclined screen 6 is fixed at the bottom of the feed pipe 5.2, a block material outlet 7 is fixed on the outer wall of the feed pipe 5.2 at the bottom of the screen 6, the block material outlet 7 is connected to a block material collecting box 8 through a pipeline, and a powder material collecting box 9 is connected to the bottom of the feed pipe 5.2. The material dropped from the belt conveyor 1 is sorted by the screen 6, the material on the screen is sent to the block material collecting box 8, and the powder material is recovered into the powder material collecting box 9.

[0026] A scraper plate 10 is fixed to the top of the hopper 5.1 near the second guide roller 3.5. The scraper plate 10 is in active contact with the bottom end of the downward belt. The function of the scraper plate 10 is to scrape the material attached to the belt conveyor 1 into the hopper 5.1, thereby ensuring the cleanliness of the belt surface and reducing the problem of attachments falling from the guide port 3.6 to the ground and affecting the surrounding environment.

[0027] The specific operation process of this embodiment:

[0028] Materials such as cement, sand, grit, stone, admixtures, water, and admixtures enter the feeding end of the belt conveyor 1 through their respective storage hoppers 5.1, and the belt conveyor 1 transports them upward to the mixer to achieve mixing of the materials;

[0029] After the belt conveyor 1 has been running for a period of time, it may become loose and material may fall through the hopper 5.1 into the block material collection box 8 and the powder material collection box 9. The operator may regularly check the status of the recovered materials in the block material collection box 8 and the powder material collection box 9, adjust the counterweight on the tensioning device 3 or replace the belt, so as to find problems and deal with them in time.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
