Technical Field

[0001] The utility model relates to the technical field of paint spraying safety protection, and in particular to a mobile pneumatic erection lifting device with controllable inclination angle. Background Art

[0002] During the painting process of large frame parts, operators are often required to climb to the top of the frame or drill into the bottom of the frame to perform pre-painting treatment (such as grinding, cleaning, protection, etc.) and painting operations. Improper operation or insufficient protective measures during this period can easily lead to safety hazards such as large frame parts overturning, falling, and injuring operators.

[0003] In order to ensure the effective and safe progress of the painting operation, it is necessary to investigate the actual conditions of the painting site, analyze the potential safety hazards, technical difficulties in operation, and quality defects in the painting process, and follow the factory safety production requirements.

[0027] See also Figures 1 to 8 The utility model provides an embodiment: a mobile pneumatic erection and lifting device with controllable inclination angle, which is used for the erection and lifting of a frame part 6. The device specifically includes a lift assembly 1, a guide rail assembly 2, a front bracket assembly 3, a rear bracket assembly 4, a push rod assembly 5, a frame part 6, and a tractor trailer 7. The lift assembly 1 and the guide rail assembly 2 are installed on the channel steel beam of the tractor trailer 7 by bolts. The axle seat bridges 18 of the front bracket assembly 3 and the rear bracket assembly 4 are formed by bending steel plates (with avoidance space) and are welded to the long longitudinal beams on both sides of the tractor trailer 7. The push rod assembly 5 connects the guide rail assembly 1 with the frame part 6. See Figure 7 In this example, it is preferred to set a front bracket assembly 3 and two rear bracket assemblies 4, which is conducive to the reversible (through the marching latch seat 17) locking support of the front bracket assembly 3 and the frame part 6 (three-point support during transportation), and the rear bracket assembly 4 and the push rod 21 form a three-point stable rotation support for the frame part 6 during the erection and lifting process. At the same time, see Figure 8 As shown in the three-dimensional schematic diagram, the tractor trailer 7 may also have retractable parking feet (e.g., four) for parking the entire device in the operating position after moving into position.

[0028] Among them, see Figure 2 The elevator assembly 1 drives the elevator input shaft 9 to rotate in the bearing seat pad 10 through the pneumatic impact wrench 8, driving the screw elevator 11 to rotate. The screw screw trapezoidal thread of the screw elevator 11 is selected to be Tr50x8 in specification to achieve self-locking, so that the frame part 6 can stop at any angle when it is erected.

[0029] See also Figure 3The guide rail assembly 2 is provided with a locking block 12 and a push block 13 that slide back and forth on the guide rail base 14.

[0034] The utility model is a mobile pneumatic erection and lifting device with controllable inclination angle, which is applied to the painting of the frame part 6. The specific operation process is as follows: when the angle of the frame part 6 stays at zero degrees, the marching pin seat 17 on the front bracket assembly 3 is inserted and locked. At this time, the tractor trailer 7 is towed to the designated painting workshop, and the painting operator performs preliminary grinding, cleaning, protection and other work on the frame part 6; then, the marching pin on the marching pin seat 17 is pulled out, and the pneumatic impact wrench 8 and the spiral lifter 11 with self-locking function are used to drive the push rod assembly 5 to erect the frame part 6 and stop at multiple angles. The operator performs comprehensive pre-painting treatment work. At this time, the shaft seat 19 and the rotary lock 20 on the rear bracket assembly 4 firmly fix the rear end of the frame part 6, and the push rod 21 and the push shaft 22 on the push rod assembly 5 firmly fix the inner side of the frame part 6 to ensure that the frame part 6 will not fall. The formal painting is carried out in two steps, and the above steps are repeated. The whole process is easy to operate and realizes automatic erection, which improves efficiency while effectively ensuring safety.
