Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a hook-type shot blasting machine with an adjustable structure. Background Technology

[0002] A suspended shot blasting machine is an industrial device that cleans and strengthens the surface of a workpiece by projecting shot. It mainly consists of a shot blaster, a separation system, and a hoisting device. Its working principle is to suspend the workpiece into a closed shot blasting chamber, where high-speed metal shot is used to remove surface impurities and strengthen surface stress.

[0003] Currently, traditional suspended shot blasting machines typically use hangers made of welded high-manganese steel bars to hold workpieces. To ensure the cleaning of a large number of workpieces at once, they are usually equipped with many branches or hooks. However, while these branches or hooks increase the number of workpieces that can be hung, they are not adaptable enough. Their spacing cannot be adjusted, which can obstruct the hanging of larger workpieces. In addition, when the number of workpieces to be cleaned is small, the high-speed shot fired by the shot blasting machine can also cause serious wear on the empty parts of the hanger, reducing the service life of the equipment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a hook-type shot blasting machine with an adjustable structure, which uses multiple sets of fixed frames with adjustable spacing. The number of hooks and fixed frames can be increased or decreased according to the size and quantity of workpieces to be cleaned, thereby reducing equipment wear, extending the service life of the equipment, and improving practicality.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a hook-type shot blasting machine with an adjustable structure, comprising: a machine body, multiple fixed frames, multiple sets of connecting mechanisms, and multiple sets of suspension mechanisms. Adjacent fixed frames are connected via the connecting mechanisms, and the uppermost fixed frame is detachably connected to the machine body.

[0007] In addition, the hook-type shot blasting machine with an adjustable structure proposed above according to this utility model may also have the following additional technical features: Specifically, the quick-release part includes a first connecting block, a second connecting block, a sleeve, a limiting block, a spring, and multiple ball bearings. The first connecting block is connected to the lower part of the first connecting rod and has a slot at its lower end. A limiting groove is formed on the outer ring surface of the first connecting block, and multiple through slots are formed at the lower part of the limiting groove. The second connecting block is connected to the upper part of the second connecting rod and is adapted to the slot. A retaining groove is formed on the ring surface of the second connecting block. The sleeve is slidably sleeved on the outside of the first connecting block. The limiting block is disposed on the inner ring surface of the sleeve and is adapted to the limiting groove. The spring is disposed between the limiting block and the upper side of the limiting groove. The multiple ball bearings are respectively disposed inside the through slots and are adapted to the retaining grooves.

[0008] Specifically, the suspension mechanism includes multiple ear plates, multiple rotating rods, multiple support rods, multiple hooks, and multiple bolts.

[0015] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following describes an embodiment of the present invention with reference to the accompanying drawings: a hook-type shot blasting machine with an adjustable structure.

[0017] like Figures 1-5 As shown, the hook-type shot blasting machine with an adjustable structure according to this utility model embodiment may include: a machine body 1, multiple fixing frames 2, multiple sets of connecting mechanisms 3 and multiple sets of suspension mechanisms 4.

[0018] Among them, two adjacent fixed frames 2 are connected by a connecting mechanism 3, and the uppermost fixed frame 2 is detachably connected to the body 1.

[0019] It should be noted that the machine body 1 described in this embodiment is a suspended shot blasting machine, which consists of a shot blasting chamber, a shot blaster, a hook system, a bucket elevator, a shot separator and a dust removal system. It can remove impurities from the surface of the workpiece and strengthen the surface stress by high-speed blasting of metal shot.

[0020] Additionally, it should be noted that the fixing frame 2 described in this embodiment is made of high manganese steel, which has high strength and hardness, strong impact resistance, and avoids rapid wear. The fixing frame 2 is arranged in a ring, which facilitates the rotation of the workpiece.

[0021] Each connecting mechanism 3 includes a first connecting rod 301, a second connecting rod 302, and a quick-release part 303.

[0022] The first connecting rod 301 is located in the middle of the lower part of the corresponding fixing frame 2, the second connecting rod 302 is located in the middle of the upper part of the corresponding fixing frame 2, and the quick-release part 303 is located between the first connecting rod 301 and the second connecting rod 302.

[0023] It should be noted that the first connecting rod 301, the second connecting rod 302, and the quick-release part 303 described in this embodiment are all made of high manganese steel, which has high strength and hardness, strong impact resistance, and avoids rapid wear. The quick-release part 303 can realize the quick installation and disassembly of the first connecting rod 301 and the second connecting rod 302.

[0024] Multiple suspension mechanisms 4 are respectively installed on corresponding fixed frames 2.

[0025] It should be noted that, in this embodiment, each fixed frame 2 has 6 suspension mechanisms 4, which are evenly distributed in a ring, so that there is enough space between two adjacent suspension mechanisms 4 to accommodate the workpiece.

[0026] Specifically, when cleaning the workpiece, the staff first adjusts the number of fixed frames 2 according to the size and quantity of the workpiece through the quick-release part 303, and adjusts the suspension mechanism 4. Then, the workpieces to be cleaned are evenly suspended on the suspension mechanism 4. The machine body 1 is started so that the suspension mechanism 4 enters the shot blasting chamber along the track and the chamber door is closed.

[0027] Then the suspension mechanism 4 begins to rotate slowly, while the shot blaster starts to propel the shot at high speed onto the surface of the workpiece to clean and strengthen the surface.

[0028] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the quick-release part 303 includes a first connecting block 3031, a second connecting block 3032, a sleeve 3034, a limiting block 3035, a spring 3036, and a plurality of balls 3038.

[0029] The first connecting block 3031 is connected to the lower part of the first connecting rod 301 and has a slot at its lower end. A limiting groove 3033 is formed on the outer ring surface of the first connecting block 3031, and multiple through grooves 3037 are formed at the lower part of the limiting groove 3033. The second connecting block 3032 is connected to the upper part of the second connecting rod 302 and is adapted to the slot. A retaining groove 3039 is formed on the ring surface of the second connecting block 3032. The sleeve 3034 is slidably sleeved on the outside of the first connecting block 3031. The limiting block 3035 is set on the inner ring surface of the sleeve 3034 and is adapted to the limiting groove 3033. The spring 3036 is set between the limiting block 3035 and the upper side of the limiting groove 3033. Multiple balls 3038 are respectively set inside the through grooves 3037 and are adapted to the retaining grooves 3039.

[0030] It should be noted that the end of the through groove 3037 described in this embodiment near the slot is set as an arc-shaped surface that fits with the ball 3038, which is used to limit the ball 3038 so that the ball 3038 can only extend into a small part of the slot, thus preventing the ball 3038 from falling out of the slot.

[0031] Additionally, it should be noted that the sleeve 3034 described in this embodiment is provided with a handle on the outside, which makes it convenient for workers to apply force to pull the sleeve 3034 upward.

[0032] Specifically, when the workpiece to be cleaned is large, and the distance between two adjacent fixed frames 2 is insufficient to accommodate the workpiece, the sleeve 3034 is moved upward by lifting the handle, so that the limiting block 3035 releases the restriction on the ball 3038. At this time, the second connecting rod 302 is pulled downward, and the second connecting block 3032 squeezes the ball 3038, causing the ball 3038 to disengage from the slot 3039 and move into the limiting groove 3033. Thus, the second connecting block 3032 can be pulled out of the slot to achieve quick disassembly of the second connecting rod 302 and the fixed frame 2. At this time, only the uppermost fixed frame 2 is left to hang large workpieces.

[0033] When reassembling the fixing frame 2, simply pull the sleeve 3034 to insert the second connecting block 3032 back into the slot. Release the handle and the sleeve 3034 will reset under the action of the spring 3036. The limiting block 3035 will push the ball 3038 back into the slot 3039, thereby fixing the second connecting block 3032 and connecting the first connecting rod 301 and the second connecting rod 302.

[0034] In one embodiment of this utility model, such as Figure 5 As shown, the suspension mechanism 4 includes multiple ear plates 401, multiple rotating rods 402, multiple support rods 403, multiple hooks 404, and multiple bolts 405.

[0035] Among them, multiple ear plates 401 are connected to the fixed frame 2 respectively, multiple rotating rods 402 are rotatably connected to the corresponding ear plates 401 respectively, multiple support rods 403 are connected to the lower end of the corresponding rotating rods 402 respectively, and multiple threaded holes 4031 are opened inside, multiple hooks 404 are respectively sleeved on the outside of the corresponding support rods 403, and multiple bolts 405 are respectively connected between the corresponding hooks 404 and the threaded holes 4031.

[0036] It should be noted that a bearing is provided between the rotating rod 402 and the ear plate 401 described in this embodiment to realize the rotation function of the rotating rod 402. The upper part of the rotating rod 402 is provided with external thread, which is used with a nut to fix the rotating rod 402 in the ear plate 401.

[0037] Understandably, the hook 404 can slide along the surface of the support rod 403, the spacing between two adjacent hooks 404 can be adjusted according to the size of the workpiece, and it can be fixed at different positions on the support rod 403 with the bolt 405 and the threaded hole 4031.

[0038] In addition, the hook 404 can be removed from the support rod 403, so that the number of hooks 404 can be adjusted according to the number of workpieces to be cleaned, avoiding unnecessary wear caused by excess hooks 404 entering the machine body 1, extending the service life of hooks 404 and saving costs.

[0039] Specifically, when the workpiece enters the machine body 1, the shot blaster starts to shoot high-speed shot, and the fixed frame 2 rotates slowly. The force generated by the shot hitting the surface of the workpiece will simultaneously drive the rotating rod 402 to rotate, thereby comprehensively cleaning and strengthening the surface of all workpieces and avoiding cleaning dead corners.

[0040] In one embodiment of this utility model, such as Figure 2 As shown, a hanging ring 5 is provided in the middle of the upper part of the upper fixing frame 2.

[0041] Understandably, the hanging ring 5 is used to connect the fixed frame 2 to the hook system of the machine body 1, thereby enabling the lifting, transportation, and rotation of the workpiece within the cleaning chamber.

[0042] In summary, the hook-type shot blasting machine with adjustable structure of this utility model can achieve quick disassembly between multiple fixed frames through the connecting mechanism, and can achieve adjustment of the hook spacing and number through the suspension mechanism. In this way, the number of hooks and fixed frames can be increased or decreased according to the size and number of workpieces to be cleaned, thereby reducing equipment wear, extending the service life of the equipment, and improving practicality.
