Technical Field

[0001] The utility model relates to the technical field of aerial work platforms, in particular to a guardrail upright pole. Background Art

[0002] Today's aerial work platforms are generally constructed with various fasteners and steel pipes, and are set by stacking them layer by layer. Specifically, especially in the field of shipbuilding, a fixed node is temporarily welded on the hull during the general shipbuilding process to facilitate construction. However, due to the application limitations of scaffolding, it is still necessary to accumulate the height layer by layer from the bottom to reach the required construction height.

[0003] Conventional vertical pole scaffolding is composed of columns, cross bars, guardrails and springboards. Referring to the structure in Chinese invention patent application CN104372935A, if the installation method is adopted, it is necessary to erect the vertical poles and cross bars layer by layer from the ground, and finally place the springboard on the cross bar at a specified height, so that workers can work on the flat plate. This construction method wastes a lot of time and delays the progress of the project. At the same time, due to the multi-step erection, the instability of the scaffolding platform is increased.

[0004] At the same time, as disclosed in the above patent application, the current guardrail construction still requires a fastener for connection. This connection method requires construction workers to carry a large amount of materials and tools for construction work. The construction is complicated and the operation time is long. Each node requires a fastener, so the traditional guardrail installation construction is very slow and inconvenient. Utility Model Content

[0008] The crossbar is placed on the bracket, the insert is inserted into the socket, and the crossbar is squeezed between the insert and the bracket, so that the crossbar can be fixed on the bracket very stably, and the installation is fast and convenient.

[0009] Specifically, the bracket is an L-shaped structure, the horizontal end of the bracket is fixedly connected to the vertical pole, and the vertical end of the bracket is bent inwardly.

[0010] Through the above arrangement, the structure of the bracket is simple and reliable, and the cross bar is further placed to slide out from the upper end of the bracket.

[0011] Specifically, the guide surface of the guide block is an inclined surface, and the insert is a wedge-shaped structure and can fit with the guide surface.

[0012] Preferably, a guide groove is provided on the guide surface, and a guide strip is provided on the corresponding surface of the insert piece and embedded in the guide groove.

[0013] Specifically, a connecting structure for installing and fixing the vertical pole is further provided at the lower end of the vertical pole.

[0014] Preferably, the connection structure is configured as a plug.

[0015] Preferably, the connecting structure is configured as a clamp.

[0016] Through the setting of plugs or clamps, the vertical poles can be connected to other vertical poles, and can also be connected to other fixed parts such as plates.

[0024] The specific structure and function of the work platform column disclosed in this invention are specifically described below.

[0025] A guardrail upright pole includes an upright pole 1 and at least one crossbar fixing portion 2. The number of crossbar fixing portions 2 is determined as required. The crossbar fixing portion 2 includes a bracket 3 and an insert 4. The bracket 3 is fixedly connected to the upright pole 1 and is used to carry a crossbar 10. The bracket 3 is provided with an insertion hole 5 for the insert 4 to pass through. A guide block 6 is fixedly connected to the upright pole 1 or the bracket 3. The insert 4 slides along the guide block 6 to pass through the insertion hole 5 and lock the crossbar. When in use, the crossbar 10 is placed on the bracket 3, and then the insert 4 is inserted downward into the insertion hole 5 with force, and the crossbar 10 is squeezed between the insert 4 and the bracket 3, so that the crossbar 10 can be fixed on the bracket 3 very stably, and the crossbar 10 and the upright pole 1 can be quickly and conveniently installed and connected.

[0026] In this embodiment, the bracket 3 adopts an L-shaped structure, the horizontal end 31 of the bracket 3 is fixedly connected to the vertical rod 1, and the vertical end 32 of the bracket 3 is bent inward.
