[0001] The utility model relates to the technical field of a van-type primer line, in particular to a telescopic ladder platform which is convenient for picking up and hanging upper and lower primer line hangers. Background Art

[0002] The inventor discovered during the process of implementing the utility model:

[0003] When the primer is unhooked and hung on the upper and lower lines, a fixed ladder platform with a length of more than 10 meters and a width of 0.48 meters is set on one side of the primer line. In order to avoid interference, the workpiece hanging point is 1.2 meters away from the fixed ladder platform. It is difficult for employees to unhook and hang the hanger, and they can only stand on the equipment to operate. However, this operation method has at least the following problems:

[0004] First, the fixed ladder platform is far away from the hanging point, which makes operation inconvenient; second, the operator needs to bend over and lean forward to operate, which is labor-intensive; third, standing on the equipment to remove and hang, there is a safety hazard of falling.

When in use, the corresponding telescopic ladder platform is extended, and the operator can directly remove and hang the sling from the fixed ladder platform to the extended telescopic ladder platform. After the operation, the telescopic ladder platform can be folded close to the fixed ladder platform without taking up space, which is convenient to use and avoids interference.

[0007] To this end, the technical solution of the utility model is: a telescopic ladder platform for conveniently picking up and hanging the upper and lower line hangers of the primer, including a fixed ladder platform, characterized in that: a telescopic ladder platform is arranged at intervals on one side of the fixed ladder platform,

[0008] The telescopic platform comprises a front frame and a rear frame which are arranged opposite to each other. The rear frame is fixed to one side of the fixed platform. Casters are arranged at the bottom of the front frame. A foldable platform is hinged between the front frame and the rear frame. When the foldable platform is extended, its height is consistent with the height of the fixed platform.

[0009] A guardrail which is convenient for insertion is hinged at the upper part between the front frame and the rear frame.

[0010] A further improvement to the above technical solution is that the front frame and the rear frame both include columns arranged on both sides, wherein: the columns on both sides of the rear frame are fixed on the fixed ladder platform, the lower part of the two columns is connected as a whole by a crossbeam, and the upper part is open to form a passage between the fixed ladder platform and the telescopic ladder platform; the columns on both sides of the front frame are fixedly connected by crossbeams, and the upper crossbeam also has the function of a guardrail, and the foldable ladder platform is hinged to the inner side of the columns on both sides. This structure has low production cost while ensuring strength and safety.

[0011] A further improvement to the above technical solution is that a guardrail is hinged on the upper part between the front frame and the rear frame for easy insertion. A specific structure is that guardrail crossbars are hinged on the outer sides of the upper ends of the two uprights of the rear frame, and the other end of the guardrail crossbar is provided with a vertically downward latch. A sleeve is provided on the front frame, and the latch is connected with the sleeve with clearance. This structure is convenient for disassembly and assembly, and after the latch is inserted into the sleeve, the overall strength and stability of the front frame and the telescopic ladder are enhanced.

[0012] A further improvement to the above technical solution is that the foldable platform includes two platforms arranged in parallel in front and behind, the platform is a frame-shaped frame, the surface is paved with a patterned aluminum plate, the bottom surfaces of the two adjacent sides of the two platforms are rotatably connected by hinges, and sleeves are respectively provided at both ends of the other side, which are rotatably connected to the round tubes arranged on the front frame and the rear frame respectively through the sleeves. This connection structure is simple and practical, low in production cost, and easy to maintain.

[0013] A further improvement to the above technical solution is that: support rods are hinged on both sides of the bottom of one of the ladder platforms, the support rods are connected as a whole by connecting rods, and the lower ends of the support rods are provided with support feet, which are round or square steel plates. The support rods are provided to play an auxiliary supporting role, further improving the safety of the telescopic ladder platform.

[0014] A further improvement to the above technical solution is that the framework used by the telescopic ladder platform is fixed by welding with rectangular tubes, so as to reduce weight and reduce production cost.

[0015] A further improvement to the above technical solution is that the surface of the telescopic ladder is provided with an anti-rust primer and a yellow topcoat, which increases the service life and makes the appearance neat and tidy, matching the production environment.

[0016] Beneficial effects: Compared with the prior art, the utility model is convenient for employees to operate, reduces labor intensity, reduces the posture level from level 5 to level 3, and at the same time reduces the risk of falling and eliminates safety hazards.
