[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figure 1-Figure 2 As shown, this embodiment provides a trench excavation protection operation platform, including a platform frame, uprights and pedals. The platform frame is composed of four cross bars 1 through corner connectors 2 to form a frame structure, the cross bars 1 and the corner connectors 4 are connected by bolts to form a detachable connection, and a support plate 3 is arranged on the platform frame. The columns 4 are used to support the platform frame, and the columns 4 pass through the corner connectors 2; there are also inclined rods 5 connected between the columns 4 and the cross bars 1, so as to increase the stability of the operating platform frame; the pedals 6 connecting the platform frame and the edge of the groove 7 are connected by bolts to form a detachable connection with the cross bars 1. The columns 4 or cross bars 1 in the same direction can also be extended in height or length by extension pieces 8 to form a column whole or a cross bar whole with matching size.

[0037] Mutually compatible through holes are arranged on the crossbar 1, the column 4, the support plate 3, the pedal 6, the corner connector 2 and the extension 8, which can facilitate the assembly of the crossbar 1, the column 4, the support plate 3, the pedal 6 and other components, and facilitate the construction of the operating platform.

[0038] Specifically, if Figure 1-Figure 5 As shown, the crossbar 1 is provided with first through holes 11 at equal intervals, and the upright column 4 is provided with second through holes 41 at equal intervals. Figure 1 , Figure 2 and Figure 6 As shown, the extension member 8 includes a first sleeve 81, a second sleeve 82 and a connecting plate 83, wherein the connecting plate 83 is located between the first sleeve 81 and the second sleeve 82, and the first sleeve 81 and the second sleeve 82 are respectively located on both sides of the connecting plate 83. Third through holes 84 are arranged at equal intervals on the first sleeve 81 and the second sleeve 82, respectively, and the intervals of the first through holes 11, the second through holes 41 and the third through holes 84 are adapted to facilitate the extension of the column 4 into the first sleeve 81 or the second sleeve 82, thereby realizing the extension of the column 4 in height, thereby forming a height suitable for the operating platform for trench construction.

[0039] Furthermore, two third through holes 84 are respectively arranged on the four side walls of the first sleeve 81 and the second sleeve 82, and the end of the column 4 is embedded in the first sleeve 81 or the second sleeve 82. The third through holes 84 of the first sleeve 81 or the second sleeve 82 coincide with the two second through holes 41 at the end of the column 4, and the end of the column 4 is fixed to the first sleeve 81 or the second sleeve 82 with bolts, thereby realizing the extension of the height of the column 4 and matching the operating platform height required for trench construction.

[0040] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the corner connector 2 is located in the middle and upper part of the column 4, and the side formed by the part of the column 4 located above the corner connector 2 is detachably connected with a protective net 9. A side formed by the part of the column 4 located above the corner connector 2 is also connected with a crossbar 10. In actual construction work, the side provided with the crossbar 10 can be located on the side where the pedal is laid, so that construction workers can enter the operating platform. Since the crossbar 10 and the column 4 are detachably connected, after the construction workers enter the operating platform, they connect the crossbar 10 and the column 4; before leaving the operating platform, they unscrew the bolts and remove the crossbar 10, and the construction workers can leave the operating platform.

Furthermore, two fourth through holes 24 are respectively arranged on the four sides of the third sleeve 22 or the fourth sleeve 23, and the end of the cross bar 1 is embedded in the third sleeve 22 or the fourth sleeve 23. The fourth through hole 24 of the third sleeve 22 or the fourth sleeve 23 coincides with the first through hole 11 at the end of the cross bar 1. The end of the cross bar 1 is fixed to the third sleeve 22 or the fourth sleeve 23 with bolts, and the four cross bars 1 are connected with four corner connectors 2 to form a platform frame, wherein the length and width of the platform frame are determined according to the conditions of the trench construction site, and cross bars of appropriate sizes are selected for assembly and connection.

In the protection area formed by the middle and upper parts of the columns 4, construction workers can carry out construction work in this area, and the protection net 9 is connected to the second through hole 41 in the middle and upper part of the column 4 by bolts or ties. Three-side protection nets and one side cross bar can be arranged to effectively protect the construction workers. In the protection area, a number of support plates 3 are arranged at the bottom, and different numbers of support plates 3 can be arranged at different positions according to construction needs. For example, when it is necessary to carry out construction operations on the pipeline under the platform frame, there is no need to connect the support plate 3 above the construction site, and the support plate 3 can be installed next to it.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 8 As shown, a pedal 6 is arranged at the edge of the connecting platform frame and the groove 7, and the pedal 6 is connected to the crossbar 1 by bolts to form a detachable connection. Specifically, a sixth through hole 61 with equal intervals is opened on one side of the pedal 6, and the interval of the sixth through hole 61 is adapted to the interval of the first through hole 11, and one side of the pedal 6 can be connected to the crossbar 1 by bolts; the other end of the pedal 6 is placed on the edge of the groove 7.

[0047] The trench excavation protection operation platform provided in this embodiment first assembles four groups of cross bars 1 through four corner connectors 2 to form a platform frame, and the ends of the four groups of cross bars 1 are respectively inserted into the third sleeve 22 or the fourth sleeve 23, and the fourth through hole 24 of the third sleeve 22 or the fourth sleeve 23 coincides with the first through hole 11 at the end of the cross bar 1, and the end of the cross bar 1 is fixed to the third sleeve 22 or the fourth sleeve 23 by bolts. Then, multiple columns 4 are formed into a column body with a suitable height through an extension piece 8, and four such column bodies are passed through the column 21 of the corner connector, and the column 21 is connected to the column 4 by bolts; the arrangement of the diagonal rod 5 increases the stability of the operation platform. A support plate 3 is arranged on the platform frame, and construction personnel can perform operations on the support plate 3.

It has a wide range of adaptability and can assemble an operating platform of adapted size according to the depth and size of the trench in the municipal engineering.

[0049] During the construction process, when the assembled operating platform surface is not sufficient for construction work, the column 4 is also connected to other cross bars and columns through another corner connector 2, and corresponding support plates are laid on the adjacent platform frames formed, and another pedal is arranged on the cross bars. After an operating platform is erected, the operating platform can be expanded according to construction needs.
