AI Technical Summary

Technical Problem

When assembling and connecting the upper and lower square frames of a traditional prefabricated safety ladder cage, the relative positions of the upper and lower square frames cannot be pre-defined, resulting in poor stability and possible shaking that may affect the connection and fixation of the workers.

Method used

A quick-install mechanism is adopted, including setting a movable threaded rod in the fixed rod. The relative position of the fixed rod and the sleeve is limited by the cooperation of the hemispherical block and the inclined plate. The threaded rod is pushed through the through hole by a spring to ensure the fixing effect, and the position is further locked by the nut and the blocking plate.

Benefits of technology

It improves the stability of the safety ladder cage, avoids loosening due to vibration, improves work efficiency, prevents the threaded rod from falling during disassembly and assembly, and simplifies the installation and disassembly process.

Description

Technical Field

[0001] The utility model belongs to the field of safety ladder cages, and in particular relates to an assembled safety ladder cage. Background Art

[0002] A safety ladder cage is a safety protection facility used at construction sites or for aerial work. It is usually used to ensure the safety of workers when working at heights. An assembled safety ladder cage is a prefabricated safety protection facility for aerial work, usually composed of multiple components, which is convenient for quick installation and disassembly at the construction site. Safety ladder cages are widely used in high pier construction of bridges, cast-in-place continuous beam construction, hanging basket construction, interchanges, deep foundation pit subway construction, tunnel entrance construction, large-scale water conservancy and hydropower projects, large-scale building basements and garage deep foundation pits, and high pier construction.

[0003] However, when assembling and connecting the upper and lower square frames, the traditional assembled safety ladder cage cannot pre-define the relative positions of the upper and lower square frames, and the stability is not ideal. Shaking may occur, affecting the subsequent complete connection and fixation of the staff. Utility Model Content

[0004] The purpose of the present utility model is to provide an assembled safety ladder cage to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An assembled safety ladder cage includes a main body, two square frames, an adapter plate arranged on the inner sides of the square frames, a staircase arranged between the adapter plates, a fixing rod arranged between the two square frames, and sleeves are provided at the top and bottom of the square frames outside the fixing rods; a quick-install mechanism includes a square column arranged inside the fixing rod, a threaded rod arranged on the outer periphery of the square column, a blocking plate arranged on the threaded rod, a spring arranged between the blocking plate and the fixing rod, a hemispherical block arranged at the front end of the threaded rod, an inclined plate arranged at the opening of the sleeve, and a through hole arranged on the sleeve; a protective mechanism is arranged at the bottom of the staircase.

[0007] Preferably, the front end of the threaded rod passes through the fixing rod, and the threaded rod is adapted to the through hole.

[0008] Preferably, a nut is threadedly provided on the threaded rod, and the hemispherical block is adapted to the inclined plate.

[0009] Preferably, two-way connecting plates are provided on all four sides of the square frame, and a protective net is installed between the four sides of two square frames via the two-way connecting plates.

[0010] Preferably, both ends of the staircase are provided with a clamping plate, and the clamping plate and the adapter plate are connected by a connecting bolt.

[0011] Preferably, the protective mechanism includes buckles respectively arranged on the clamping plates, a net is provided between the buckles at the bottom of the stairs, and a clamping hole is provided on the net around the buckles.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model provides a movable threaded rod in the fixing rod, and during the process of inserting the fixing rod into the sleeve, the hemispherical block will contact the inclined plate, thereby applying an oblique thrust to the threaded rod in the fixing rod until it completely enters the sleeve. After the threaded rod is aligned with the through hole, the spring will use its own elasticity to push the threaded rod through the through hole, thereby limiting the relative position of the fixing rod and the sleeve, which is convenient for personnel to fully fix subsequently and avoids the situation where loosening due to vibration affects work efficiency. When the safety ladder cage needs to be dismantled after work is completed, it is only necessary to push the threaded rod slightly, and when the hemispherical block contacts the inner side of the through hole, an oblique thrust can be applied to the threaded rod again, thereby improving work efficiency. The threaded rod is always located in the fixing rod, avoiding the situation where the threaded rod falls off and is lost during disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As can be seen from the above, after the threaded rod 205 passes through the through hole 201, the staff can rotate and install the nut 208 on the threaded rod 205 so that it cooperates with the blocking plate 204 to limit the position of the threaded rod 205 and improve the anti-slip effect. Through the two-way connecting plate 108, a protective net 109 can be installed between the square frame 101 and the upper and lower adjacent square frames 101 to protect the inside of the safety ladder cage.
