Description

Technical Field

[0001] The utility model relates to the technical field of a bridge construction protection device, and specifically relates to a bridge construction protection device which is easy to assemble. Background Art

[0002] Bridge construction is the process of building a bridge according to the design content, which mainly refers to bridge construction technology and work organization. During the construction process, safety is the most important issue that needs to be paid attention to. There are many protective measures used in existing bridge construction. The most important one is to use scaffolding as the basis, and then install protective nets on the scaffolding. However, due to the diverse structures of scaffolding, the installation and disassembly of protective nets is very inconvenient.

[0003] As a prior art, Chinese patent CN 210127414 U proposes a bridge construction protection device, which realizes a detachable connection between a protection net and a column. However, in this technical solution, it is still necessary to adopt a locking fit between threaded holes and bolts to connect the two. In actual operation, it is still relatively cumbersome, and the bolts are also easy to lose during the disassembly and installation process. In addition, the staff also need to disassemble the protection net when entering and exiting the protection device, which is troublesome and there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a bridge construction protection device which is easy to assemble, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present utility model adopts the following technical scheme: a bridge construction protection device which is easy to assemble, comprising a base plate, columns at the four corners above the base plate, a roller at the bottom of the base plate, a pair of grooves with an angle of 90 degrees formed on the side walls of the columns, the grooves extending along the length direction of the columns and passing through the top ends of the columns, the cross-sectional shape of the grooves being in the shape of a "convex" character, a connecting component being provided between every two columns, the connecting component comprising a pair of connecting frames and a pair of plug-in columns provided on the sides of the pair of connecting frames away from each other, the cross-sectional shape of the plug-in columns being able to be plugged in and matched with the cross-sectional shape of the grooves, a protective net or a door structure being provided between the pair of connections; and a locking component for pressing or unlocking the tops of the plug-in columns is also provided.

[0006] By adopting the above technical scheme, during installation, a pair of plug posts are inserted from the upper end of the groove and pushed upward to connect a pair of connecting frames to the columns. The groove is set to a concave shape so that the plug posts and the grooves are fixed more tightly. The tops of the plug posts are then pressed by the clamping assembly to fix the connecting columns and the columns. Compared with the prior art, the steps of locking and matching the threaded holes and the bolts are eliminated, and the operation is time-saving and labor-saving. A door body structure is set between the connecting frames, and the staff can enter and exit the protective device by opening the door body. Compared with the prior art, the steps of disassembling the protective net for entering and exiting are eliminated, which is more convenient and flexible.

[0007] As a further optimization of the present invention, the locking assembly includes a fixed rod arranged on the top of the column and a locking plate connected to the fixed rotation, and the locking plate can be simultaneously interlaced with the corresponding pair of grooves in the vertical direction after deflection.

[0008] By adopting the above technical solution, when the column is inserted into the groove, the locking plate is operated to deflect. After the locking plate rotates, it intersects with a pair of grooves in the vertical direction at the same time, so that the columns in the corresponding pair of grooves can be compressed and locked. When unlocking is required, the locking plate is deflected in the opposite direction.

[0009] As a further optimization of the present invention, the columns include a first column, a second column, a third column and a fourth column, a door body structure is provided between the first column and the second column, and the door body structure includes a double-leaf door rotatably connected to a corresponding pair of connecting frames and a latch assembly provided on the double-leaf door.

[0010] With the above technical solution, when a worker enters or exits the protective device, the double-door is rotated to open for entry or exit, and when the double-door is closed, it can be locked by the latch assembly.

[0011] As a further optimization of the utility model, a magnetic block is fixed on the top of the column, and a magnet capable of being attracted to the magnetic block is provided on the side of the locking plate.

[0012] With the above technical solution, when the locking plate presses and locks the plug post, the magnet and the magnetic block are attracted to each other, thereby fixing the angle of the locking plate to prevent it from deflecting in the opposite direction.

[0013] As a further optimization of the present invention, a protective pad is provided on the inner side of the double-leaf door, and the surface height of the protective pad is greater than the surface height of the door latch assembly.

[0014] By adopting the above technical solution, when a worker is located in the protective device, the protective pad can prevent the worker from colliding with the door latch or the door, provide a buffer, and prevent the worker from being injured.

[0015] The beneficial effects of the utility model are as follows: during installation, a pair of plug posts are inserted from the upper end of the groove and pushed toward it, thereby connecting a pair of connecting frames to the columns, and the groove is set to a concave shape, so that the plug posts and the grooves are fixed more tightly, and then the tops of the plug posts are pressed by the clamping assembly to achieve the fixation of the connecting columns and the columns. Compared with the prior art, the steps of locking and matching the threaded holes and the bolts are eliminated, and the operation is time-saving and labor-saving. A door body structure is set between the connecting frames, and the staff can open the door body to enter and exit the protective device. Compared with the prior art, the steps of disassembling the protective net for entering and exiting are eliminated, which is more convenient and flexible. BRIEF DESCRIPTION OF THE DRAWINGS
