Description

Technical Field

[0001] This utility model relates to the field of truck body processing technology, and in particular to a lifting device structure for electrophoretic coating treatment of truck bodies. Background Technology

[0002] After the overall welding and processing of the truck body is completed, the entire truck body needs to be hoisted and transported to be immersed in an electrophoresis pool. The inner and outer layers of the truck body are then immersed in the electrophoresis treatment to form a rust-proof coating on the surface of the truck body, thereby improving the rust-proof effect of the truck body in actual use.

[0003] like Figure 4 As shown, this is the lifting device structure used in the electrophoretic coating process of the previous generation of truck bodies. The truck body processed in the previous step is placed in the middle of the lower lifting beam. Then, the lifting equipment can adjust the upper lifting beam to be directly above the lower lifting beam. Finally, when the lock on the vertical beam is screwed into the lock groove on the lower lifting beam, the entire truck body can be lifted between the upper and lower lifting beams. However, this type of lifting device has the following shortcomings in actual use: Since the vertical beam can be rotatably installed on the upper lifting beam, and the vertical beam can be rotated and locked with the lower lifting beam through the lock, a parallelogram structure is formed between the upper lifting beam, the vertical beam, and the lower lifting beam. When the truck body stops during lifting, due to inertia, the entire lower lifting beam can swing back and forth under the upper lifting beam. If the swing amplitude is too large, it is easy to cause abnormal problems such as the lower lifting beam falling off the vertical beam and the truck body shaking and falling. There are certain safety risks in actual use.

[0004] In view of this, it is particularly important to design and manufacture a lifting device structure that can effectively reduce the detachment and swaying of the lower lifting beam and improve the safety and stability of lifting operations, and to apply it to the electrophoretic coating process of truck bodies. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the previous generation of truck body electrophoretic coating treatment lifting device structure is prone to shaking under force during actual use, which reduces the safety and stability of the lifting electrophoretic treatment. Therefore, a new lifting device structure for truck body electrophoretic coating treatment is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lifting device structure for electrophoretic coating treatment of truck bodies includes an upper lifting beam, a lower lifting beam located directly below the upper lifting beam, and vertical beams located between the four corners of the upper and lower lifting beams. The four vertical beams are rotatably mounted on the four corners of the upper lifting beam. The lower ends of the vertical beams are fixedly connected with latches. The four corners of the lower lifting beams are provided with locking grooves that match the latches. A support mechanism is provided between the upper lifting beam, the lower lifting beam, and the vertical beams to strengthen the overall anti-detachment and anti-swaying of the lifting device.

[0008] As a further description of the above technical solution:

[0009] The support mechanism includes a support frame rotatably mounted on the outer sides of the upper and lower ends of the vertical beam, an external stud screwed onto the free end of the support frame by a thread, upper locking frame holes opened on the left and right sides of the front and rear ends of the upper lifting beam to accommodate the external stud screw, and lower locking frame holes opened on the left and right sides of the front and rear ends of the lower lifting beam to accommodate the external stud screw.

[0010] As a further description of the above technical solution:

[0011] The upper and lower lifting beams are fixedly connected to the left and right sides of their front and rear ends, respectively, to support the auxiliary support of the free end of the rotating frame. The supporting slider has a guide arc groove on the side facing the rotating frame to guide the rotating frame into the inner side of the supporting slider.

[0012] As a further description of the above technical solution:

[0013] A knob is installed at the outer end of the external stud, and multiple grooves arranged in a ring array are formed on the outside of the knob.

[0014] As a further description of the above technical solution:

[0015] The vertical beam has a central locking frame hole on the side facing the external stud to accommodate the external stud.

[0016] As a further description of the above technical solution:

[0017] The upper end of the upper beam is fixedly connected to a suspension seat with an isosceles triangular structure, and the suspension seat has a lifting hole in the middle.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] In this utility model, the original lifting device structure has been scientifically and rationally improved. A support rotating frame, external studs, and knobs are set on the vertical beams. At the same time, a support slider, an upper locking frame hole, and a lower locking frame hole are set between the upper and lower lifting beams. After the lower lifting beam is locked and installed below the four vertical beams, the support rotating frames on the upper and lower sides of the vertical beams can be screwed into the support sliders upward and downward through the guide arc grooves, respectively. Then, by holding and rotating the knob on the support rotating frame, the external studs can be screwed inward into the upper locking frame hole of the upper lifting beam and the lower locking frame hole of the lower lifting beam. This structure can strengthen the support at the corners between the upper, vertical, and lower lifting beams, creating a load-bearing triangular structure at the corners of the lifting device. This reduces the occurrence of abnormal problems such as swaying, displacement, and falling during the lifting electrophoresis of the carriage, thereby improving the safety and stability of the lifting electrophoresis of the carriage.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4This utility model provides a technical solution: a lifting device structure for electrophoretic coating treatment of truck bodies, including an upper lifting beam 1, a lower lifting beam 2 located directly below the upper lifting beam 1, and vertical beams 3 located between the four corners of the upper lifting beam 1 and the lower lifting beam 2. The four vertical beams 3 are rotatably installed at the four corners of the upper lifting beam 1. The lower end of the vertical beam 3 is fixedly connected with a latch 301. The four corners of the lower lifting beam 2 are provided with locking grooves 201 that match the latches 301. A support mechanism for strengthening the overall anti-detachment and anti-sway of the lifting device is provided between the upper lifting beam 1, the lower lifting beam 2, and the vertical beams 3.

[0028] Specifically, such as Figure 1-3 As shown, the support mechanism includes a support frame 4 rotatably mounted on the outer sides of the upper and lower ends of the vertical beam 3; an external stud 5 screwed onto the free end of the support frame 4; upper locking bracket holes 7 located on the left and right sides of the front and rear ends of the upper lifting beam 1 to accommodate the external stud 5; and lower locking bracket holes 8 located on the left and right sides of the front and rear ends of the lower lifting beam 2 to accommodate the external stud 5.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the upper beam 1 and the lower beam 2 are fixedly connected to the left and right sides of the front and rear ends of the upper beam 1 and the lower beam 2, respectively, for auxiliary support of the free end of the rotating frame 4. The supporting slider 202 has a guide arc groove 203 on the side facing the supporting rotating frame 4 for guiding the supporting rotating frame 4 to slide into the inner side of the supporting slider 202. The supporting rotating frame 4 can slide into the supporting slider 202 through the guide arc groove 203, thereby realizing the positioning operation of the upper external stud 5 of the supporting rotating frame 4 with the upper locking frame hole 7 or the lower locking frame hole 8, which facilitates the establishment of a fixed connection between the supporting rotating frame 4 and the upper beam 1 and the lower beam 2.

[0030] Specifically, such as Figure 1-3 As shown, a knob 501 is installed on the outer end of the external stud 5, which facilitates the operator's gripping and rotation adjustment of the outer end of the external stud 5. Multiple grooves arranged in a ring array are provided on the outside of the knob 501, which effectively increases the contact area between the operator's hand and the knob 501.

[0031] Specifically, such as Figure 1-3 As shown, a central locking frame hole 6 for accommodating the outer stud 5 is provided on the side of the vertical beam 3 facing the outer stud 5. When not in use, the support frame 4 can rotate towards the middle of the vertical beam 3, and then the outer stud 5 is screwed inward into the central locking frame hole 6 on the vertical beam 3, thus limiting and fixing the support frame 4 to the outside of the vertical beam 3.

[0032] Specifically, such as Figure 1 and Figure 2As shown, a lifting seat 101 with an isosceles triangular structure is fixedly connected to the middle of the upper end of the upper lifting beam 1. A lifting hole is opened in the middle of the lifting seat 101. The hook of the lifting equipment is hooked into the lifting hole on the lifting seat 101, and a lifting connection can be established with the upper lifting beam 1.

[0033] Working principle: During use, the carriage requiring electrophoresis is pre-positioned and installed in the middle of the lower lifting beam 2. Then, the operator can use the hoisting equipment to move the upper lifting beam 1 above the carriage. The operator on the ground can then hold and rotate the vertical beam 3, screwing the locking buckle 301 at the bottom of the vertical beam 3 into the locking groove 201 of the lower lifting beam 2. At this point, the entire carriage is initially fixed between the upper lifting beam 1, the vertical beam 3, and the lower lifting beam 2. Then, the operator can rotate the support frames 4 on both sides of the vertical beam 3 upwards and downwards into the upper lifting beam, respectively. 1. Inside the support slider 202 of the lower beam 2, the free end of the support frame 4 can slide into the inner side of the support slider 202 along the guide arc groove 203. Then the operator can hold and turn the knob 501 to screw the outer stud 5 on the support frame 4 into the upper locking frame hole 7 of the upper beam 1 or the lower locking frame hole 8 of the lower beam 2. At this time, a triangular support reinforcement will be formed between the corner of the upper beam 1 and the vertical beam 3 and between the corner of the vertical beam 3 and the lower beam 2, which will provide auxiliary reinforcement at the connection node.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
