Description

Technical Field

[0001] This application relates to the field of sprinkler truck ladder manufacturing technology, and in particular to a tooling for welding sprinkler truck ladders. Background Technology

[0002] The water tank ladder (also known as the water tank ladder) is used to help operators climb to the top of the water tank. When installing the water tank ladder, additional connectors are needed at the top and bottom of the ladder. The connectors on the ladder are connected to the mounting bases on the platform and the water tank, respectively, and then fixed in place.

[0003] For example, Chinese patent application number 202420022611.5 discloses a water tank ladder structure for a sprinkler truck that is easy to install and adjust in height. It includes a platform plate installed at the rear end of the vehicle frame, a ladder body set on the platform plate, mounting seats movably fitted on the surfaces of both ends of the ladder body, external docking holes equidistantly arranged on the mounting seats along the vertical direction, and internal docking holes equidistantly arranged on both ends of the ladder body along the vertical direction. Movable pins are movably inserted into the internal docking holes and the external docking holes.

[0004] like Figure 2 As shown, a typical water truck ladder includes two parallel handrail pipes 100 and multiple foot pedals 200 vertically connected between the two handrail pipes 100. The top of the handrail pipes 100 is usually provided with a bend 300 for easy connection to the water tank.

[0005] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement: Compared to common straight ladders, sprinkler truck ladders have an added curved section at the top. This irregular structure makes it difficult to fix and position the handrails and footboards during the welding process, hindering efficient assembly and manufacturing of sprinkler truck ladders. Utility Model Content

[0007] This application provides a tooling for welding ladders on sprinkler trucks, employing the following technical solution: A welding fixture for a sprinkler truck ladder includes a base, multiple positioning components, and a bending fixing part. The positioning components are arranged one-to-one with the foot pedals of the sprinkler truck ladder. The positioning components are fixedly installed on the upper surface of the base. The two handrail tubes of the sprinkler truck ladder are respectively engaged in two first positioning grooves formed on both sides of the positioning components.

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a tooling for welding ladders on sprinkler trucks. (Refer to...) Figure 1-2 The welding fixture for the sprinkler truck ladder includes a base 1, multiple sets of positioning components 2, and a bending and fixing part 3. The positioning components 2 are arranged one-to-one with the foot pedals 200 of the sprinkler truck ladder. The positioning components 2 are fixedly installed on the upper surface of the base 1. The two handrail tubes 100 of the sprinkler truck ladder are respectively snapped into the two first positioning grooves formed on both sides of the positioning components 2. The positioning components 2 are also provided with movable positioning grooves. The foot pedals 200 of the sprinkler truck ladder are located in the movable positioning grooves. The width of the movable positioning grooves is greater than the thickness of the foot pedals 200 of the sprinkler truck ladder. The bending and fixing part 3 is fixedly installed at the end of the base 1. The bending and fixing part 3 is used to snap and fix the bending part 300 of the sprinkler truck ladder. In addition, the upper surface of the base 1 is also provided with multiple support beams 4. The support beams 4 are parallel to the foot pedals 200 of the sprinkler truck ladder. The support beams 4 are used to support the handrail tubes 100 of the sprinkler truck ladder.

[0028] The base 1 can be welded from steel or cast from concrete to ensure the structural stability of the entire fixture, making it difficult to shake and facilitating rapid assembly.

[0029] In this embodiment, the positioning component 2 has two sets of partition structures, which are located at both ends of the foot pedal 200 of the sprinkler truck ladder. Each partition structure includes a lower inner stop 21, a lower outer stop 22, an upper inner stop 23, and an upper outer stop 24, all vertically fixed to the upper surface of the base 1. The lower inner stop 21 simultaneously abuts against the inner side of the handrail tube 100 of the sprinkler truck ladder and the bottom of the foot pedal 200 of the sprinkler truck ladder. The lower outer stop... Part 22 is located outside the handrail tube 100 of the water truck ladder. The gap width between the lower inner stop 21 and the lower outer stop 22 is greater than the diameter of the handrail tube 100 of the water truck ladder. The upper inner stop 23 abuts against the inner side of the handrail tube 100 of the water truck ladder. The upper outer stop 24 abuts against the outer side of the handrail tube 100 of the water truck ladder. The gap width between the lower inner stop 21 and the upper inner stop 23 is greater than the thickness of the foot pedal 200 of the water truck ladder.

[0030] Specifically, the lower inner stop 21 is a rectangular steel plate, the lower outer stop 22 is an L-shaped steel plate, and the upper inner stop 23 and the upper outer stop 24 are both square steel pipes.

[0031] The positioning component 2 designed above has a simple and stable structure and is easy to manufacture. It facilitates the quick placement and positioning of the handrail pipe 100 and foot pedal 200 of the sprinkler truck ladder, thereby accelerating the subsequent welding process.

[0032] In this embodiment, the bending fixing part 3 has two sets of limiting fixing structures. The two sets of limiting fixing structures respectively fix and clamp the bending parts 300 of the two handrail pipes 100 of the sprinkler truck ladder. The limiting fixing structure includes an end column 31, an outer column 32 and an inner column 33, which are all vertically fixed to the upper surface of the base 1. The end column 31 abuts against the top of the sprinkler truck ladder, the outer column 32 abuts against the outside of the bending part 300 of the sprinkler truck ladder, and the inner column 33 abuts against the inside of the bending part 300 of the sprinkler truck ladder.

[0033] Specifically, the top of the inner column 33 is provided with a guide plate 34 that is inclined inward, the end column 31 and the inner column 33 are both channel steel, and the outer column 32 is square steel pipe.

[0034] The bending fixing part 3 designed above has a simple and stable structure and is easy to manufacture. It facilitates the quick placement and positioning of the bending part 300 of the sprinkler truck ladder, making it less prone to shaking and improving the stability during the welding process.

[0035] The beneficial technical effects of the tooling for welding the ladder of the sprinkler truck according to the embodiments of this application are roughly as follows: The positioning component 2 can quickly fix and position the handrail tube 100 and foot pedal 200 of the sprinkler truck ladder, and the bending fixing part 3 can quickly fix and position the bending part 300 of the sprinkler truck ladder, which is conducive to the efficient assembly and manufacturing of sprinkler truck ladders and improves production efficiency.
