Technical Field
[0001] This utility model relates to the field of roller conveyor technology for shot blasting machines, specifically a removable bracket device for an in-machine roller conveyor. Background Technology
[0002] In shot blasting equipment, the roller conveyor is a key conveying component, mainly responsible for carrying and transporting the workpiece to be cleaned through the shot blasting chamber. The roller conveyor is usually cylindrical in shape. Due to the long-term impact and wear of high-speed shot and the heavy load of the workpiece, the wear-resistant sleeve and end protective sleeve of the roller conveyor are prone to severe wear or even breakage, requiring disassembly and replacement of the roller conveyor. Similarly, when the equipment needs to be redesigned for process layout, the roller conveyor also needs to be disassembled and replaced.
[0003] Currently, roller conveyors typically adopt a fixed installation structure, which is rigidly connected to the equipment frame. Disassembly requires the release of multiple fastening points. When disassembling the roller conveyor, it is not convenient for operators to remove the roller conveyor in a narrow space, and there are also safety hazards in manually handling heavy roller conveyors. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model provides an easy-to-remove bracket device for in-machine roller conveyors.
[0005] The technical solution of this utility model is as follows:
[0006] A machine roller conveyor easy-to-remove bracket device includes two sets of symmetrically arranged moving units. Each moving unit includes a main support with an elongated frame structure. The upper surfaces of the main supports of the two moving units are connected by a support plate. The two moving units are spaced apart. Multiple fixed connecting plates are provided below the main support. Guide wheel sets are detachably connected to the fixed connecting plates. The guide wheel sets have guide wheels.
[0007] The machine has a track below the roller conveyor, which includes two parallel guide rails. The guide wheels of the two moving units are respectively connected to the track in a rolling manner.
[0008] The upper surface of the pallet is provided with multiple steel plates, which are arranged at equal intervals along the length of the pallet and are perpendicular to the pallet. The upper surface of the steel plates is the roller bearing surface, which is an arc-shaped surface.
[0009] The length direction of the track, the length direction of the main support, the length direction of the pallet, and the moving direction of the guide wheels are all consistent with the length direction of the roller conveyor.
[0010] To facilitate better support of the roller conveyor by the bearing surface, the ratio of the diameter of the bearing surface to the outer diameter of the roller conveyor is 1-3.
[0011] Furthermore, the central angle corresponding to the bearing surface of the roller conveyor ranges from 60° to 120°.
[0012] The main support structure is as follows: the main support includes two parallel I-beams, each I-beam including an upper plate and a lower plate that are parallel to each other. The upper plate and the lower plate are connected by a vertical web. The support plate is detachably connected to the upper plate by a first connector. The two upper plates are connected by an upper connecting plate that is flush with them, and the two lower plates are connected by a lower connecting plate that is flush with them.
[0013] To protect the I-beams and prevent deformation from collisions during use, the upper and lower plates of the same I-beam are connected by multiple support plates. These support plates are arranged at equal intervals along the length of the I-beam, and are perpendicular to both the upper plate and the web. The support plates are located on the outer side of the web and inside the I-beam.
[0014] Preferably, the tray extends to the middle of the corresponding upper connecting plate on both sides along the width direction of the main support.
[0015] Preferably, the length direction of the fixed connecting plate is parallel to the length direction of the I-beam, and two limiting blocks are provided on both sides of the fixed connecting plate along its length direction, with the two limiting blocks located on both sides of the guide wheel.
[0016] The guide wheel has the following structure: it includes two symmetrically arranged bearing seats, which are rotatably connected by a rotating shaft, and the rotating shaft is equipped with a rubber wheel that is compatible with the guide rail.
[0017] The beneficial effects of this utility model are as follows:
[0018] The structure adopts two or more sets of symmetrical moving units + detachable guide wheel sets to achieve rapid assembly and separation. After disassembling the roller conveyor, the roller conveyor is placed on the steel plate. The roller conveyor is moved in and out by pushing and pulling the moving unit, which replaces the manual dragging of the roller conveyor. This not only improves maintenance efficiency, but also improves construction safety.
[0019] The pallet and the main support can be detachably fixed through the first connector, which makes it easy to adjust the support range according to the length of the roller conveyor, adapt to the disassembly requirements of roller conveyors of different specifications, and is also suitable for use on tracks of different widths.
[0020] The curved roller conveyor bearing surface fits tightly against the outer wall of the roller conveyor, providing uniform force support and avoiding local stress concentration that could lead to roller conveyor deformation.
[0021] The rolling connection method of double guide rails and guide wheel sets ensures that the bracket moves smoothly along a straight line, preventing deviation or jamming, and is especially suitable for operation in narrow machine spaces;
[0022] The I-beam steel main support (with built-in support plate) forms a box-shaped anti-bending structure, which significantly improves the overall rigidity and avoids deformation when transporting heavy-duty roller conveyors. Attached Figure Description

Shot blasting machine. Detailed Implementation
[0031] See Figure 1 , Figure 2 and Figure 5 As shown, an in-machine roller conveyor easy-to-remove bracket device includes two sets of symmetrically arranged moving units. Each moving unit includes a main support 1 with an elongated frame structure. The upper surfaces of the main supports 1 of the two moving units are connected by a support plate 2. The two moving units are spaced apart. Multiple fixed connecting plates 3 are provided below the main support 1. The multiple fixed connecting plates 3 are arranged along the length direction of the roller conveyor 9.
[0032] Below the roller conveyor 9 inside the machine is a track 5, which includes two parallel guide rails. Each fixed connecting plate 3 is detachably connected to a set of guide wheels 4. The set of guide wheels 4 has guide wheels 4, and the guide wheels 4 of the two moving units are respectively tumblingly connected to the track 5.
[0033] The upper surface of the pallet 2 is provided with multiple steel plates 6, which support the roller conveyor 9. The multiple steel plates 6 are arranged at equal intervals along the length of the pallet 2 and are perpendicular to the pallet 2. The upper surface of the steel plates 6 is the roller conveyor bearing surface 601, which is an arc-shaped surface. To facilitate better support of the roller conveyor 9 by the roller conveyor bearing surface 601, the ratio of the diameter of the roller conveyor bearing surface 601 to the outer diameter of the roller conveyor 9 is 1-3; the central angle of the roller conveyor bearing surface 601 ranges from 60° to 120°.
[0034] The length direction of track 5, the length direction of main support 1, the length direction of pallet 2, and the moving direction of guide wheel 4 are all consistent with the length direction of roller conveyor 9.
[0035] See Figure 3 As shown, the main support 1 includes two parallel I-beams 101. Each I-beam 101 includes an upper plate 1011 and a lower plate 1012 that are parallel to each other. The upper plate 1011 and the lower plate 1012 are connected by a vertical web 1013. The support plate 2 is detachably connected to the upper plate 1011 by a first connecting member. The two upper plates 1011 are connected by an upper connecting plate 102 that is flush with them, and the two lower plates 1012 are connected by a lower connecting plate 103 that is flush with them. The first connecting member can be a fastening bolt.
[0036] The support plate 2 extends to the middle of the corresponding upper connecting plate 102 on both sides along the width direction of the main support 1, thereby increasing the contact area and effective connection area between the support plate 2 and the corresponding upper plate 1011, which facilitates the stable connection of two adjacent main supports 1.
[0037] To protect the I-beam 101 and prevent deformation during use, the upper plate 1011 and lower plate 1012 of the same I-beam 101 are connected by multiple support plates 7. The multiple support plates 7 are arranged at equal intervals along the length of the I-beam 101. The support plates 7 are perpendicular to the upper plate 1011 and the web plate 1013 respectively. The support plates 7 are set on the outer side of the web plate 1013 and are located inside the I-beam 101.
[0038] See Figure 4 As shown, the length direction of the fixed connecting plate 3 is parallel to the length direction of the I-beam 101. Two limiting blocks 8 are provided on both sides of the fixed connecting plate 3 along its length direction. The limiting blocks 8 are strip-shaped structures, and their length direction is perpendicular to the length direction of the fixed connecting plate 3. The two limiting blocks 8 are located on both sides of the guide wheel 4. The guide wheel 4 has the following specific structure: it includes two symmetrically arranged bearing seats 401. The housings of the bearing seats 401 are threadedly connected to the fixed connecting plate 3 by bolts. The two bearing seats 401 are rotatably connected by a rotating shaft 402. The rotating shaft 402 is equipped with a rubber wheel 403 adapted to the guide rail, and the rotating shaft 402 is perpendicular to the track 5.
[0039] In this embodiment, the roller conveyor 9 is responsible for conveying the workpiece to be cleaned. It needs to be replaced when the layout is adjusted or when the wear-resistant sleeve and end protective sleeve of the roller conveyor 9 are severely worn or broken. When disassembling the roller conveyor 9, a hook is used to lift one end of the roller conveyor 9 and place it on the roller bearing surface 601 of the steel plate 6. An external mechanical device is then used to move the other end of the roller conveyor 9 out of the machine. At this time, under the action of the guide wheel 4, the roller conveyor 9 moves along a straight line with the disassembly bracket device, thus smoothly removing the roller conveyor 9 from the shot blasting machine 10, further facilitating the disassembly of the roller conveyor 9 by the workers and improving work efficiency.
