Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a suspension chain through-type tanker shot blasting machine with anti-fall-off properties. Background Technology

[0002] The overhead conveyor shot blasting machine is a new type of specialized equipment designed and manufactured according to user requirements. It features static loading and unloading of workpieces, automatic and rapid conveying and positioning, and rotating shot blasting. Suitable for large-volume, all-around shot blasting cleaning of cast steel, cast iron, and welded parts, it is applicable to various types of hangable workpieces. Shot blasting not only removes rust from the workpiece surface and cleans weld slag from structural components, but also eliminates welding stress and improves the fatigue strength of the workpiece. Existing overhead conveyor shot blasting machines are prone to workpiece detachment during operation. Therefore, we aim to improve the working efficiency of the overhead conveyor shot blasting machine and prevent workpiece detachment through innovation.

[0003] A search revealed that patent publication number CN215547914U discloses a suspension chain shot blasting machine for tank trucks designed to prevent detachment. The machine includes a chassis and a limiting frame. Shot blasting machines are installed on both sides of the chassis, and a passageway is provided at the top. A support frame is installed on the outside of the chassis, with a track connected to the top of the support frame. The track connects to the top of the suspension chain frame, and a threaded rod is fixed to the bottom of the suspension chain frame. A hanging rod is installed below the threaded rod, and a sleeve is connected to the outside of the threaded rod. Support plates are fixed to both sides of the sleeve. This suspension chain shot blasting machine for tank trucks prevents detachment by rotating the support plates to drive the sleeve and threaded rod through threaded transmission. This allows the sleeve to drive the support plates for height adjustment. Furthermore, the two ends of the tightening chain are respectively connected to connecting rings and pull rings, so that the symmetrically distributed tightening chains tighten the tank truck frame on both sides, effectively preventing the suspension chain tank truck from detaching during suspension.

[0004] Based on the above search and analysis of existing technologies, while existing overhead conveyor shot blasting machines for tank trucks, similar to those disclosed above, can effectively prevent workpieces from falling off, they typically require manual removal after cleaning. Furthermore, the presence of anti-fall-off structures makes workpiece removal relatively cumbersome. Therefore, a new overhead conveyor shot blasting machine for tank trucks with anti-fall-off features is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide a non-detachable overhead conveyor shot blasting machine for tank trucks, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a suspension chain through-type tank truck shot blasting machine with anti-fall-off function, comprising a machine body with a shot blaster installed at the top, and an annular track installed at the top of a support frame and penetrating the inner cleaning cavity of the machine body, wherein multiple suspension chain assemblies are equidistantly mounted on the annular track along its length.

[0007] The catenary assembly includes suspension rods, suspension columns, anti-slip blocks, and unloading components;

[0008] The suspension rod is slidably installed at the lower end of the circular track. Multiple suspension columns and anti-detachment blocks are provided. Multiple suspension columns are evenly rotated and installed on the side end of the suspension rod and connected to the suspension rod by torsion springs. Multiple anti-detachment blocks are slidably installed on the free end of multiple suspension columns and can protrude from the upper surface of the suspension column.

[0009] The unloading assembly is installed on the suspension rod. The circular track is located outside the discharge port of the cleaning machine body and is equipped with an auxiliary unloading component that is compatible with the unloading assembly. When the suspension assembly reaches the auxiliary unloading component, the unloading assembly cooperates with the auxiliary unloading component to make the suspension column rotate downward until its free end is lower than its rotating end, and the anti-detachment block slides to be completely stored inside the suspension column at the same time. When the suspension assembly leaves the auxiliary unloading component, the suspension column rotates upward under the elastic force of the torsion spring until its free end is higher than its rotating end, and the anti-detachment block slides to protrude from the upper surface of the suspension column at the same time.

[0010] As a further supplement to this solution, the unloading assembly includes a connecting rope, a conical ring, a connecting rod, and a lifting ring;

[0011] Multiple lifting rings are provided, and each lifting ring is correspondingly set on the upper side of multiple suspension columns. Both the conical ring and the lifting ring are vertically sleeved on the outside of the suspension rod. The conical ring is located at the top of the suspension rod and is adapted to the auxiliary unloading component. The conical ring and the lifting ring are connected by a connecting rod. Multiple abutments are fixed at the lower end of the lifting ring, and the multiple abutments are vertically corresponding to each of the multiple suspension columns.

[0012] The side end of the suspension rod is equipped with a fixed shaft for the suspension column to rotate and install. One end of the connecting rope is fixed to the upper end of the fixed shaft, and the other end of the connecting rope passes through the suspension column and is fixed to the anti-detachment block. The free end of the suspension column is provided with a through hole for the anti-detachment block to slide and be stored. A compression spring fixed to the anti-detachment block is connected in the through hole.

[0013] As a further supplement to this solution, a fixing ring is fixed on the suspension rod, and the fixing ring is provided with a sliding hole through which the connecting rod slides.

[0014] As a further supplement to this solution, a roller is rotatably mounted on the bottom end of the abutment block, and the roller contacts the upper surface of the suspension column.

[0015] As a further supplement to this solution, a stop plate is installed at the top of the suspension rod. The width of the stop plate is greater than the overall width of the suspension chain assembly. Dustproof plates are elastically slidably installed at the inlet and outlet of the cleaning machine body.

[0016] As a further supplement to this solution, the auxiliary unloading component can be detachably installed on the circular track.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. In this utility model, by sliding the anti-detachment block on the free end of the suspension column and allowing it to protrude from the upper surface of the suspension column, the workpiece can be effectively prevented from detaching from the suspension column. Through the coordinated arrangement of the unloading component and the auxiliary unloading component, when the suspension component reaches the auxiliary unloading component, the unloading component, in conjunction with the auxiliary unloading component, causes the suspension column to rotate downward until its free end is lower than its rotating end. At this time, the workpiece can smoothly slide down the suspension column at an angle, completing the automatic unloading action. This practical design makes the operation more convenient and reliable.

[0019] 2. In this utility model, by setting the abutment plate, the width of the abutment plate is greater than the overall width of the overhead conveyor assembly. The abutment plate can push the dustproof plate to one side and can prevent the dustproof plate from contacting the workpiece during the process of the workpiece entering and exiting the cleaning machine body with the overhead conveyor assembly, thereby preventing the workpiece from being tripped by the dustproof plate during the process of the workpiece entering and exiting the cleaning machine body with the overhead conveyor assembly.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Reference Figure 1-5 The present invention relates to a suspension chain through-type tank truck shot blasting machine for preventing detachment, comprising a machine body 1 with a shot blaster 2 mounted on the top, and an annular track 4 mounted on the top of a support frame 3 and passing through the cleaning cavity inside the machine body 1. Multiple suspension chain assemblies 5 are equidistantly mounted on the annular track 4 along its length. The annular track 4 and the suspension chain assemblies 5 adopt a conventional sliding fit method in the prior art, and conventional drive elements are used to drive the suspension chain assemblies 5 to slide cyclically along the annular track 4.

[0030] Among them, the catenary assembly 5 is used to hang the relevant parts of the tank truck, which will be referred to as the workpiece in the following text.

[0031] The overhead conveyor assembly 5 includes a suspension rod 51, a suspension column 52, an anti-detachment block 54, and a discharge assembly. The suspension rod 51 is slidably installed on the lower end of the annular track 4. Multiple suspension columns 52 and anti-detachment blocks 54 are provided. Multiple suspension columns 52 are evenly rotated and installed on the side end of the suspension rod 51 and connected to the suspension rod 51 by a torsion spring. The torsion spring is made of a spring material with high elasticity, which can ensure that the suspension rod 51 will not rotate excessively downward when hanging general workpieces, thus preventing the workpiece from falling off. Multiple anti-detachment blocks 54 are slidably installed on the free end of multiple suspension columns 52 one by one and can protrude from the upper surface of the suspension column 52, which can effectively prevent the workpiece from falling off the suspension column 52. The discharge assembly is installed on the suspension rod 51. The annular track 4 is located outside the discharge port of the cleaning machine body 1 and is equipped with an auxiliary discharge component 6 that is compatible with the discharge assembly.

[0032] Based on the above structural arrangement, when the catenary assembly 5 reaches the auxiliary unloading component 6, the unloading assembly cooperates with the auxiliary unloading component 6 to cause the suspension column 52 to rotate downward until its free end is lower than its rotating end, and the anti-detachment block 54 slides to be completely housed inside the suspension column 52 at the same time; when the catenary assembly 5 leaves the auxiliary unloading component 6, the suspension column 52 rotates upward under the elastic force of the torsion spring until its free end is higher than its rotating end, and the anti-detachment block 54 slides to protrude from the upper surface of the suspension column 52 at the same time.

[0033] Regarding the unloading assembly, specifically, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the unloading assembly includes a connecting rope 56, a conical ring 58, a connecting rod 59, and a lifting ring 510. Multiple lifting rings 510 are provided, and each lifting ring 510 is correspondingly positioned on the upper side of multiple suspension columns 52. Both the conical ring 58 and the lifting ring 510 are vertically sleeved on the outside of the suspension rod 51. The conical ring 58 is located at the top of the suspension rod 51 and is adapted to the auxiliary unloading component 6. The conical ring 58 and the lifting ring 510 are connected by the connecting rod 59. The lower part of the lifting ring 510... Multiple abutments 511 are fixed at one end, and the multiple abutments 511 are vertically corresponding to multiple suspension columns 52. A fixed shaft 53 for the suspension column 52 to be rotatably mounted is installed on the side end of the suspension rod 51. One end of the connecting rope 56 is fixed to the upper end of the fixed shaft 53, and the other end of the connecting rope 56 passes through the suspension column 52 and is fixed to the anti-detachment block 54. The free end of the suspension column 52 is provided with a through hole for the anti-detachment block 54 to slide and be stored. A compression spring 55 fixed to the anti-detachment block 54 is connected in the through hole.

[0034] Based on the above structural arrangement, when the overhead conveyor assembly 5 reaches the auxiliary unloading component 6, the conical surface of the conical ring 58 abuts against the auxiliary unloading component 6, causing the conical ring 58 to move down synchronously with multiple lifting rings 510 via the connecting rod 59. The downward-moving abutment block 511 abuts against the suspension column 52 and rotates it downward until the free end of the suspension column 52 is lower than its rotating end. The anti-detachment block 54 is limited by the length of the connecting rope 56 and slides to be completely stored inside the suspension column 52. At this time, the workpiece can smoothly slide down the suspension column 52 at an angle and complete the automatic unloading action.

[0035] When the overhead conveyor assembly 5 leaves the auxiliary unloading component 6, the suspension column 52 rotates upward under the elastic force of the torsion spring until its free end is higher than its rotating end. At this time, the anti-detachment block 54 is no longer restricted by the connecting rope 56 and slides to the upper surface protruding from the suspension column 52, completing the reset and allowing the next set of workpieces to be hung.

[0036] The suspension rod 51 is fixed with a fixing ring 57, and the fixing ring 57 is provided with a sliding hole for the connecting rod 59 to slide through, which can prevent the lifting ring 510 from rotating when the suspension rod 51 is a round rod, causing the abutment 511 and the suspension column 52 to be misaligned.

[0037] Among them, a roller is rotatably installed at the bottom end of the abutment block 511, and the roller contacts the upper surface of the suspension column 52, which can reduce the contact friction.

[0038] The cleaning machine body 1 has a dustproof plate 8 that is elastically slidably installed at the inlet and outlet. For example, it is connected to the cleaning machine body 1 by a spring. When closed, it can effectively prevent dust and can automatically close after being opened. In order to prevent the workpiece from being tripped by the dustproof plate 8 during the process of the suspension assembly 5 entering and exiting the cleaning machine body 1, a stop plate 7 is installed at the top of the suspension rod 51. The width of the stop plate 7 is greater than the overall width of the suspension assembly 5. The stop plate 7 can push the dustproof plate 8 to one side and prevent the dustproof plate 8 from contacting the workpiece during the process of the workpiece entering and exiting the cleaning machine body 1 with the suspension assembly 5.

[0039] Among them, the auxiliary unloading component 6 can be detachably installed on the circular track 4, and the unloading position can be adjusted according to actual needs.

[0040] The working principle of this utility model is as follows: The catenary assembly 5 slides cyclically along the annular track 4. When the catenary assembly 5 reaches the auxiliary unloading component 6, the conical surface of the conical ring 58 abuts against the auxiliary unloading component 6, causing the conical ring 58 to move synchronously downwards along with multiple lifting rings 510 via the connecting rod 59. The downward-moving abutment block 511 abuts against the suspension column 52, causing it to rotate downwards until the free end of the suspension column 52 is lower than its rotating end. Meanwhile, the anti-detachment block 54, limited by the length of the connecting rope 56, slides until it is completely housed inside the suspension column 52. Figure 6 As shown, at this time, the workpiece can smoothly slide down the suspension column 52 to complete the automatic unloading action; when the suspension chain assembly 5 leaves the auxiliary unloading part 6, the suspension column 52 rotates upward under the elastic force of the torsion spring until its free end is higher than its rotating end. At this time, the anti-detachment block 54 is not restricted by the connecting rope 56 and slides to the upper surface protruding from the suspension column 52 to complete the reset, so that the next set of workpieces can be hung.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
