[0001] The utility model relates to the technical field of wave-breaking plate assembly, in particular to special equipment for assembling wave-breaking plates on liquid tank trucks. Background Art

[0002] With the development of the automobile industry, automobile transportation is an important part of liquid transportation. Automobiles have the characteristics of convenience, speed, and efficiency. Automobile transportation generally adopts the form of tank transportation mounted on a tractor, and there are also single-vehicle tanks. Therefore, the tank body is of great importance. In the tank body manufacturing and assembly process, the wave-breaking plate is a very important component in the design of the liquid tank truck. It is mainly used to reduce the fluctuation and impact of the liquid inside the tank body and improve the driving stability of the vehicle. The existing wave-breaking plate assembly of liquid tank trucks is all manual operation. The wave-breaking plate is manually lifted into the tank, shaped through the lining mold, and adjusted and installed with tools such as sledgehammers and crowbars. After the installation and riveting are completed, manual welding is used. The existing wave-breaking plate assembly mainly has the following major problems:

[0004] 2. The noise is loud. During the positioning and adjustment process of the wave-breaking plate, it is necessary to use tools such as sledgehammers and crowbars to knock and adjust the direction and position, which causes a lot of noise on site.

[0005] 3. The operation is intensive. The lining mold and wave-breaking plate need to be manually lifted into the tank body and fixed. At the same time, they need to be constantly hammered with a sledgehammer when positioning. The working space inside the tank is small, and manual installation and adjustment are required constantly, which increases the workload of employees.

[0006] 4. Product quality cannot be guaranteed. The process of using a sledgehammer to smash the board has a great impact on the structure of the wave-breaking board, and the product quality cannot be guaranteed. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a special equipment for assembling wave-breaking plates of liquid tank trucks, which can adapt to the assembly of wave-breaking plates of tanks of different models. The wave-breaking plates are automatically centered, automatically grasped, and sent into the tank (through a heavy-duty operating machine, the lifting and telescopic dimensions are automatically adjusted according to the cross-sections of different types of tanks). At this time, the wave-breaking plates sent into the tank are in an inclined state, and need to be assembled in place through the tightening mechanism on the grasping device (manual assistance is provided by adjusting the position of the tightening mechanism on the grasping device through a button).

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0014] Furthermore, a swing electric cylinder device is installed between the telescopic hydraulic jacking device and the adjacent vacuum suction cup device.

[0015] Furthermore, the telescopic hydraulic jacking device consists of a connecting arm and a telescopic arm.

[0016] Furthermore, the loading device is mainly composed of a positioning pin, a driving cylinder device, a main frame, a connecting rod mechanism, a slide plate, and a slide rail; the rodless end of the driving cylinder device is installed on the main frame, and the rod end is connected to the slide plate; a slide plate is provided on the slide plate, and a plurality of positioning pins are movably installed in the slide groove; the slide plate is movably connected to the parallel slide rail on the main frame; the connecting rod mechanism has a centripetal contraction function, the center of which is hinged at the center position of the main frame, and the two ends are respectively hinged to the slide plates at both ends of the slide rail; a plurality of support devices are also installed on the main frame.

[0034] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. Unless there is a conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0035] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects.

[0036] like Figure 1 The figure shows a dedicated device for assembling wave-breaking panels on a tank truck. The device comprises a heavy-duty manipulator unit 1, a gripping device 2, a loading device 4, a clamp-type positioner 5, and a rear blocking and limiting unit 6. The heavy-duty manipulator unit 1 has lifting and retracting functions. The gripping device 2 is mounted on the heavy-duty manipulator unit, which drives the gripping device 2 up and down and forward and backward to adjust its position. The loading device 4 is used to place the wave-breaking panels to be installed and automatically aligns the panels. The loading device 4 is mounted on a slide 7 below the gripping device 2, allowing it to move between fixed positions. When the loading device 4 is directly below the gripping device 2, it facilitates the gripping device 2 to grasp the wave-breaking panels. When the loading device 4 moves to the outer end of the slide 7, the incoming material device 3 facilitates the transfer of the wave-breaking panels to the loading device 4. The clamp-type positioner 5 is used to secure the tank. It is mounted within the movable range of the gripping device 2. The gripping device 2 grasps the wave-breaking panels and transfers them to the tank for installation. The rear blocking limit unit 6 abuts against the rear end of the liquid tank to prevent the tank body from moving when the wave-breaking plate is assembled, positioned and tightened.

[0037] like Figure 2 As shown, the heavy-duty manipulator unit 1 includes a lifting drive unit 1-1, a frame unit, and a telescopic unit. The lifting drive unit 1-1 is mounted on the frame unit, and the telescopic unit is mounted on the lifting drive unit 1-1 via a lifting slide 1-4. The lifting drive unit 1-1 drives the telescopic unit up and down via the lifting slide 1-4, adjusting the height of the telescopic unit. The telescopic unit includes a telescopic drive unit 1-3 and an arm assembly 1-5. The arm assembly 1-5 is mounted on the telescopic drive unit 1-3, and the telescopic drive unit 1-3 drives the arm assembly 1-5 to extend and retract. The telescopic drive unit 1-3 is mounted on the lifting slide 1-4, and the lifting drive unit 1-1 drives the telescopic drive unit 1-3 up and down. The lifting drive unit 1-1 and the telescopic drive unit 1-3 work together to adjust the height and telescopic state of the arm assembly 1-5.

[0038] like Figure 3As shown, the gripping device 2 includes a rotating device, a gripping device 2 frame, a vacuum suction cup device 2-5, and a telescopic hydraulic jacking device 2-7. One end of the rotating device is mounted on the telescopic unit via an arm connecting bracket 2-1, specifically on the front end of the arm assembly 1-5. The other end of the rotating device is connected to the gripping device 2 frame, driving the gripping device 2 frame to rotate and achieve angle adjustment. The rotating device includes a rotary cylinder device 2-2 and a rotating cylinder device 2-3. The rotary cylinder device 2-2 is connected to the rotating cylinder device 2-3 via a bracket, forming a right angle relationship. The rotary cylinder device 2-2 is connected to the arm assembly 1-5 via the arm connecting bracket 2-1, and the rotating cylinder device 2-3 is connected to the gripping device 2 frame. The rotary cylinder device 2-2 rotates 180° along its axis, driving the gripping device 2 frame to rotate 180° within its plane. The rotating cylinder device 2-3 rotates 180° along its axis, driving the gripping device 2 frame to rotate 180° up and down. Vacuum suction cups 2-5 are fixedly mounted at the four corners of the gripping device 2 frame to grip the breakwater. These suction cups are ball-jointed universal structures, adaptable to curved surfaces. Telescopic hydraulic jacking devices 2-7 are mounted on the left and right sides of the gripping device 2 frame. These devices are used to firmly and securely position the breakwater within the tank. These devices consist of a connecting arm 2-7.1 and a telescopic arm 2-7.2, each with a 300mm travel. When the gripping device 2 delivers the breakwater to a predetermined position within the tank, the telescopic arm 2-7.2 extends to securely position the breakwater. To achieve the tightening and positioning of the wave-breaking plate within liquid tanks of different diameters, a telescopic hydraulic jacking device 2-7 is hingedly connected to the frame of the gripping device 2. This allows the telescopic hydraulic jacking device 2-7 to swing within the plane of the gripping device 2 frame, adjusting the relative position of the telescopic hydraulic jacking device 2-7 to accommodate liquid tanks of different diameters. Specifically, when the two telescopic hydraulic jacking devices 2-7 are in the same horizontal position, the distance between the outer ends of the two telescopic hydraulic jacking devices 2-7 is the largest, corresponding to the liquid tank with the largest diameter. When the two telescopic hydraulic jacking devices 2-7 form an angled relationship, the smaller the acute angle formed, the smaller the distance between the outer ends of the two telescopic hydraulic jacking devices 2-7, corresponding to the liquid tank with a smaller diameter. The swing angle of the telescopic hydraulic jacking device 2-7 within the plane of the gripping device 2 frame is controlled by a swinging electric cylinder device 2-4. One end of the swinging electric cylinder device 2-4 is hinged to the vacuum suction cup device 2-5 adjacent to the telescopic hydraulic jacking device 2-7, and the other end is hinged to the telescopic hydraulic jacking device 2-7. The swing electric cylinder device 2-4 controls the swing of the telescopic hydraulic jacking device 2-7 in a telescopic manner, and the controlled swing angle is 38°±10%.

[0039] like Figure 4As shown, the loading device 4 is mainly composed of a positioning pin 4-1, a driving cylinder device 4-2, a main frame 4-3, a connecting rod mechanism 4-5, a slide plate 4-6, and a slide rail 4-7. The rodless end of the driving cylinder device 4-2 is installed on the main frame 4-3, and the rod end is connected to the slide plate 4-6. The slide plate 4-6 is provided with a slide groove, and multiple positioning pins 4-1 are movably installed in the slide groove. The positioning pins 4-1 can be adjusted and locked in the slide groove. The slide plate 4-6 is movably connected to the parallel slide rail 4-7 on the main frame 4-3 and can move along the slide rail 4-7 under the drive of the driving cylinder device 4-2. The connecting rod mechanism 4-5 is a folding rod structure, the center of which is hinged at the center position of the main frame 4-3, and its two ends are respectively hinged to the slide plate 4-6 at both ends of the slide rail 4-7. When the driving cylinder device 4-2 moves the chute plate 4-6 at one end, the connecting rod mechanism 4-5 folds, driving the chute plate 4-6 at the other end to move synchronously toward each other, thus centering the wave-breaking plate. Multiple support devices 4-4 are also mounted on the main frame 4-3 to provide support for the wave-breaking plate on the main frame 4-3. After the wave-breaking plate is transported to the loading device 4, the corresponding position of the positioning pin 4-1 is adjusted according to the specifications of the wave-breaking plate to position it. The driving cylinder device 4-2 drives the wave-breaking plate to adaptively align itself, and the loading device 4 feeds the wave-breaking plate along the slide 7 to the bottom of the grasping device 2 for easy grasping.

[0040] like Figure 5 As shown, the clamp-type positioner 5 includes two clamp ring frames 5-1, which are mounted on a track 5-5 in a front-to-rear manner. The bottom of the clamp ring frame 5-1 is mounted on the track 5-5 via a clamp ring moving device 5-4, which drives the clamp ring frame 5-1 to move on the track 5-5. The clamp ring frame 5-1 is equipped with a clamp ring rotating device 5-3 for driving the clamp ring to rotate. The clamp ring frame 5-1 is equipped with multiple sets of clamping devices 5-2 for securing the liquid tank. Each set of clamping devices 5-2 has an independent servo-controlled clamping stroke, which can meet the clamping requirements of tanks of different diameters and oval tanks. Before the liquid tank is transported to the two clamp ring racks 5-1, the clamp ring racks 5-1 are moved on rails 5-5 by a clamp ring moving device 5-4. The distance between the two clamp ring racks 5-1 is adjusted to accommodate tanks of different lengths. The two clamp ring racks 5-1 are clamped onto both ends of the tank and clamped by a clamping device 5-2 to secure the tank. When the liquid tank needs to be rotated, the clamp ring rotating device 5-3 drives the clamp ring to rotate, driving the liquid tank to rotate.

[0041] like Figure 6As shown, the rear blocking and limiting unit 6 comprises a rear blocking and limiting frame 6-1 and a movable device 6-2. The rear blocking and limiting frame 6-1 is a frame structure mounted on the movable device 6-2 and moves back and forth on the track 5-5 via the movable device 6-2. When the wave-breaking plate is assembled, positioned, and tightened, the liquid tank may move. The rear blocking and limiting unit 6 is moved to the rear end of the tank via the movable device 6-2 to lock it, and the rear blocking and limiting frame 6-1 abuts against the tank to prevent movement. The rear blocking and limiting unit 6 moves on the track 5-5 to accommodate tanks of varying lengths.

[0042] The working process of the special equipment for assembling wave-breaking plates for tank trucks is as follows:

[0043] ① First, the liquid tank body is transported to the clamp type positioner 5. According to the specifications of the liquid tank, the spacing of the clamp ring frame 5-1 is adjusted to clamp and fix the liquid tank. The rear blocking limit unit 6 is positioned at the rear side of the liquid tank.

[0044] ② Lift the wave-breaking plate onto the loading device 4 and drive the cylinder device 4-2 to control the centering of the wave-breaking plate; the loading device 4 moves along the slide 7 to the bottom of the grabbing device 2.

[0045] ③ The heavy-duty manipulator controls the arm assembly 1-5 to move to the top of the loading device 4. The gripping device 2 adjusts the gripping device 2 frame to the gripping posture (i.e., the vacuum suction cup device 2-5 is horizontally facing downward) through the rotating device. After the vacuum suction cup device 2-5 grabs the wave-breaking plate, it is flipped upward through the rotating device. The wave-breaking plate is in a vertical state. The heavy-duty manipulator controls the arm assembly 1-5 to extend forward and send the wave-breaking plate to the predetermined assembly position in the liquid tank, and then the operator takes over.

[0046] ④ If the wave-breaking plate is not in place in the liquid tank, it can be tightened into place by the telescopic hydraulic tightening device 2-7 on the grabbing device 2.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
