Description

Technical Field

[0001] This utility model relates to the field of inclined ladder manufacturing, and in particular to an inclined ladder assembly tooling. Background Technology

[0002] In various products used for working at heights, inclined ladders are typically included to facilitate personnel movement. Currently, the manufacturing process for inclined ladders is relatively simple, usually involving manually marking lines to determine the angle and step spacing before construction.

[0003] A typical inclined ladder consists of two side beams, treads connecting the two beams, and safety railings installed on the beams. During the manufacturing process of an inclined ladder, welding between the beams and treads is required. Since the beams are relatively long, they are usually laid vertically and then welded. However, when the beams are laid vertically, they may tip over. Therefore, tooling is needed to fix the beams in place to prevent them from tipping over.

[0004] However, existing fixtures for fixing ladder beams often require bolts, nuts, and other fasteners to secure them, making the installation and removal of ladder beams very cumbersome. In addition, most existing fixtures are designed for fixing ladder beams of a single specification. When fixing ladder beams of various specifications, multiple different fixtures are required, increasing production costs. Utility Model Content

A fixed base, the fixed base including a support area at the bottom, a placement area at the middle, and a limiting area at the top; The bottom of the support area has a pair of support segments arranged in an inverted V shape; The placement area has a placement groove for placing the bottom side of the ladder beam. The placement groove includes a horizontal groove and a vertical groove that are connected in a figure-7 shape. When the bottom side of the ladder beam is placed in the placement groove, the side wall of the ladder beam is in contact with the side wall of the fixed base. The limiting area is provided with a limiting plate to limit the upper side of the ladder beam. The limiting plate has a limiting groove for the upper side of the ladder beam to be embedded. The limiting plate is movably connected to the fixed base. The fixed base also has several mounting holes distributed from top to bottom for connecting the limiting plate.

[0007] Furthermore, a fixing plate is connected to the placement area on the fixed base. The fixing plate is fixed to the bottom of the placement groove by bolts and nuts. The upper side of the fixing plate has a V-shaped groove. When the bottom side of the ladder beam is placed in the placement groove, the bottom end of the ladder beam is located at the bottom of the V-shaped groove, and the inner wall of the V-shaped groove is in contact with the outer wall of the ladder beam.

[0008] Furthermore, the connection between the limiting plate and the fixed base is as follows: the limiting plate and the fixed base are connected by bolts and nuts. The limiting plate also has a through hole for the bolt to pass through. The bolt passes through the mounting hole on the fixed base and the through hole on the limiting plate in sequence and is then fixed by the nut. A gap is left between the limiting plate and the fixed base so that the limiting plate can rotate freely relative to the bolt.

[0009] Furthermore, a vertically upward-extending lifting rod is connected to the top of the fixed base.

[0010] Furthermore, a reinforcing brace is connected to the outer side of the support section. The reinforcing brace includes a reinforcing plate and a reinforcing round tube connected vertically. An arc-shaped opening that fits against the outer wall of the reinforcing round tube is also opened at the side end of the support section. The reinforcing plate is fixed to the side wall of the fixed base.

[0011] The advantages of this utility model are as follows: The assembly fixture of this utility model places the bottom of the ladder beam in the placement groove and uses a limiting plate to limit the upper side of the ladder beam, thus completing the fixation between the ladder beam and the fixed base. There is no need to use bolts, nuts or similar fasteners to achieve fixation, which is very convenient. In addition, by setting several connecting holes distributed from top to bottom on the fixed base, the corresponding connecting holes can be selected according to the size of the ladder beam to install the limiting plate, so as to meet the fixing requirements of ladder beams of different sizes. It is suitable for fixing ladder beams of various specifications.

[0012] The fixed plate is designed to work in conjunction with the placement slot on the fixed base to further limit and fix the bottom end of the ladder beam, so that the ladder beam can be better fixed to the fixed base.

[0013] The design of the reinforcing brace on the outside of the support section is to provide stable support for the bottom of the fixed base, so as to ensure that the fixed base itself can be placed stably on the ground and avoid the ladder beam from shaking or tilting due to the instability of the fixed base itself.
