Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction equipment, in particular to a tunnel locking foot anchor rod construction work platform. Background Art

[0002] During tunnel construction, the installation of locking anchors is an important step in ensuring the stability of the tunnel structure. Traditional locking anchor construction usually relies on temporary scaffolding or other supporting devices. However, the construction and removal of scaffolding is not only time-consuming and labor-intensive, but also poses certain safety hazards. In narrow spaces such as tunnels, the use of scaffolding becomes more difficult, and often requires special design and construction techniques to adapt to the space limitations and construction requirements on site.

[0003] Existing construction platforms are not flexible and adaptable, especially when faced with construction environments with different heights and angles, and cannot quickly and accurately adjust the height and angle of the platform. In addition, these platforms are usually large in size and not easy to carry and store in a small space, which increases the difficulty and time of construction preparation. Utility Model Content

[0010] As a preferred solution of the utility model, the rotation angle range of the support rod 1 is between parallel to the platform plate and perpendicular to the platform plate.

[0011] As a preferred solution of the utility model, one side of the second support rod is groove-shaped, and the width and depth of the groove are the same as the width and thickness of the first support rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the platform plate and the movable bracket can be folded, which reduces the space occupied by the work platform when idle, facilitates storage and transportation, and is particularly suitable for construction environments in narrow spaces such as tunnels.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-8 , a specific implementation of the utility model is:

[0024] like Figure 1-2 As shown, a tunnel locking anchor construction work platform is composed of multiple platform plates 1 and multiple movable brackets 2. The multiple connected platform plates 1 can be folded and unfolded to facilitate stacking and transportation in a small space. The movable brackets 2 can rotate and adjust the length to adjust the angle of the platform plates 1. The platform plates 1 connected to each other from top to bottom are a group. Multiple groups of platform plates 1 can be freely disassembled and assembled to form work platforms of different sizes to meet the construction needs under different conditions.

[0025] like Figure 3-5 As shown, the main body of the platform plate 1 is a rectangular base plate 11. Two slide rails 12 are provided at the bottom of the base plate 11, and two track blocks 13 are provided at the top of the base plate 11. The slide rails 12 and the track blocks 13 are both T-shaped and are respectively arranged at the two ends of the base plate 11. Stoppers 17 are provided at the two ends of the inner part of the slide rail 12 to prevent the track blocks 13 from escaping from the slide rail 12. A plurality of transverse stiffening ribs 14 are provided on the upper part of the base plate 11, which can not only increase the strength of the platform plate 1, but also play an anti-slip role. A plurality of connecting rings 15 are provided on the side of one end of the base plate 11, and the same number of connecting rods 16 are provided on the other end. The connecting rods 16 are inverted L-shaped. The two platform plates 1 can be connected by inserting the connecting rods 16 into the connecting rings 15.

[0026] like Figure 6 As shown, a sloped anti-slip block 18 is provided on one side of the bottom platform plate 1, and a plurality of anti-slip holes 19 are provided on the anti-slip block 18. Rods fixed to the ground can be passed through the anti-slip holes 19 to fix the entire working platform.

[0027] like Figure 7-8As shown, the movable bracket 2 is composed of a support rod 1 21 and a support rod 22. The support rod 1 21 is connected to the base plate 11 through a rotating shaft 23 on the side of the platform plate 1. A stopper is provided on the rotating shaft 23 to limit the rotation angle of the support rod 1 21, so that it can rotate within a range between parallel to the platform plate 1 and perpendicular to the platform plate 1. One side of the support rod 22 is in a groove shape, and the width and depth of the groove are the same as the width and thickness of the support rod 1 21. The support rod 1 21 can be placed in the groove to make the support rod 22 slide along the support rod 1 21. A plurality of positioning holes 1 24 are provided on the support rod 1 21, and a plurality of positioning holes 25 are provided on the support rod 22. The support rod 22 is connected to the support rod 1 21 through a fixing bolt 26. By aligning different positioning holes 25 with the positioning holes 1 24 and installing the fixing bolt 26, the length of the support rod 22 extending out of the range of the support rod 1 21 can be changed, thereby achieving the effect of changing the length of the movable bracket 2.

[0028] The utility model proposes a tunnel locking foot anchor construction work platform which has the characteristics of being foldable, assembleable, and adjustable in height and angle. When idle, each platform board 1 is retracted to overlap along the slide rail 12 and the movable bracket 2 is turned to be parallel to the platform board 1. At this time, the work platform is small in size, space-saving for stacking, and easy to carry in the narrow space of the tunnel. After the tunnel arch construction is completed, it is necessary to lock the foot anchor for arch construction. Since the construction of the locking foot anchor has requirements for the height of the construction point and the angle of the anchor, the lack of a corresponding construction platform will increase the difficulty of construction. At this time, the work platform is unfolded and placed at the construction site, and the movable bracket 2 is turned to the vertical direction of the platform board 1 in turn and erected on the ground. The height of the movable bracket 2 is adjusted so that the height and angle of the platform board 1 meet the requirements of the on-site construction. Short steel bars are inserted into the anti-slip holes 19, and the construction of the locking foot anchor can be carried out.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
