[0028] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and components are not described in detail.

[0029] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0030] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include," "comprising," and similar words should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to."

[0031] In the description of the present invention, it should be understood that the terms "first," "second," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0032] Reference Figure 1-4The present invention provides a foundation pit canopy structure, comprising a track 1, a drive assembly 2, a curtain 3, and a support assembly 4. The track 1 is fixed to both sides of the foundation pit, the drive assembly 2 is disposed on the track 1, and the curtain 3 is fixed between two adjacent drive assemblies 2. The relative movement of two adjacent drive assemblies 2 can drive the curtain 3 to open or close. The support assembly 4 is disposed between adjacent drive assemblies 2 to ensure the strength of the foundation pit canopy structure.

[0033] A plurality of drive assemblies 2 are arranged along the extension direction of the track 1, and at least three groups of drive assemblies 2 are provided. It should be noted that the specific number of drive assemblies 2 can be changed according to the length of the foundation pit. The drive assembly 2 includes two sliding rods 21, and the two sliding rods 21 are respectively provided on both sides of the foundation pit. The sliding rod 21 includes a vertical rod 211 and a base 212. The base 212 is slidably connected to the upper side of the track 1 along the extension direction of the track 1. The lower side of the base 212 is provided with two rotatable casters 22. The axial direction of the casters 22 is perpendicular to the extension direction of the track 1. A servo motor 23 is fixed to the lower side of the base 212. The output shaft of the servo motor 23 is connected to the axis of a caster 22. When the servo motor 23 is working, it can drive the caster 22 to rotate, thereby driving the sliding rod 21 to move alone along the extension direction of the track 1.

[0034] A connector 5 is connected between the two sliding rods 21 of the same drive assembly 2, and the two sides of the curtain 3 are fixed to two adjacent connectors 5 respectively. When the two sliding rods 21 of the same drive assembly 2 slide, the connector 5 can be driven to move synchronously, thereby pulling one side of the curtain 3 to move. In the present application, casters 22 and a motor driving the casters 22 to move are provided below each sliding rod 21, so that each sliding rod 21 can move stably and synchronously. When a part of the foundation pit needs to open the curtain 3 for shielding, the foundation pit canopy structure in the unfolded state of the present application can be moved as a whole to the position where shielding is required. It is only necessary to relatively unfold the two adjacent drive assemblies 2 on both sides of the required curtain 3 to achieve partial shielding. Similarly, if shielding of more areas is required, more drive assemblies 2 can be moved to open other curtains 3. The foundation pit canopy structure provided by the present application can complete the partial expansion or closing of the foundation pit canopy, and has good flexibility and adaptability.

[0035] As an embodiment, the track 1 includes a main strip beam 11 and a side strip beam 12. The side strip beam 12 and the main strip beam 11 have the same extension direction. Two side strip beams 12 are provided, which are respectively fixed to the two sides of the main strip beam 11. A T-shaped slider is fixed to the middle part of the lower side of the base 212. A T-shaped slide groove 111 is provided on the upper side of the main strip beam 11. The slider is slidably connected in the slide groove 111. Strip grooves 121 are provided above the strip beams 12 on both sides. The casters 22 can slide in the strip grooves 121. By setting the slide grooves 111 and the strip grooves 121, the sliding direction of the sliding rod 21 can be limited, thereby improving the sliding stability of the sliding rod 21.

[0036] As an embodiment, a connecting plate 24 is fixedly connected to one side of the base 212. One end of the connecting plate 24 extends to the side of the base 212. A first drive cylinder 241 is fixedly connected to the connecting plate 24. The first drive cylinder 241 is vertically arranged. The telescopic rod of the first drive cylinder 241 extends to the lower side of the connecting plate 24 and is fixedly connected to a pressure block 242. The pressure block 242 can be tightly pressed against the bottom surface of the slide groove 111. When the sliding rod 21 moves to the desired position, the first drive cylinder 241 can press the pressure block 242 downward, so that the pressure block 242 is pressed into the slide groove 111, thereby limiting the position of the sliding rod and maintaining the stability of the curtain 3.

[0037] As an embodiment, the connecting member 5 is a steel pipe, the two ends of which are respectively fixed to the upper side of the sliding rod 21. A plurality of fixing rings 31 are fixed to one side of the curtain 3. The steel pipe is passed through the plurality of fixing rings 31, so that one side of the curtain 3 can be fixed between the two sliding rods 21. It should be noted that the connecting member 5 can also be an existing steel wire rope, which can also achieve the connection effect, but the middle part of the steel wire rope is prone to concave, causing the middle part of the curtain 3 to sink. The use of a steel pipe can avoid the sinking of the curtain 3 and can ensure that the sliding rods 21 on both sides of the foundation pit move the same distance, so that the curtain 3 can be unfolded effectively.

[0038] Each vertical rod 211 is connected to two lifting blocks 25 for sliding movement in the vertical direction. The support assembly 4 includes two cross-arranged support rods 41. The middle parts of the two support rods 41 are connected to each other through a rotating shaft, so that the two support rods 41 can rotate around the rotating shaft. The two ends of the support rod 41 are respectively connected to the adjacent drive assembly 2, and the two ends of the support rod 41 are respectively connected to the lifting blocks 25 on the upper and lower sides and are rotatably connected. When the two sliding rods move along the extension direction of the track 1, the two support rods 41 can rotate along the rotating shaft, and the lifting blocks 25 can meet the up and down movement of the two ends of the support rods 41. The support rods 41 can enhance the connection strength between the adjacent drive assemblies 2 of the foundation pit canopy structure, thereby improving the stability of the canopy structure.

[0039] As an embodiment, a receiving slot 29 is defined in the middle of the vertical pole 211. A second drive cylinder 291 is fixedly connected to the receiving slot 29. The telescopic rod of the second drive cylinder 291 is downwardly disposed. A clamping block 292 is fixedly connected to the lower end of the telescopic rod of the second drive cylinder 291. The upper side of the clamping block 292 abuts against the lifting block 25 located on the lower side of the vertical pole 211, thereby limiting the position of the lifting block 25. The second drive cylinder 291 and the clamping block 292 prevent the lifting block 25 from falling off the vertical pole 211, ensuring that the support assembly 4 can stably provide support.

[0040] The implementation principle of the present utility model is as follows: in the present application, casters 22 and motors driving the casters 22 are provided below each sliding rod 21, so that each sliding rod 21 can move stably and synchronously. When a part of the foundation pit needs to be shielded by opening the curtain 3, the foundation pit canopy structure in the unfolded state of the present application can be moved as a whole to the position where shielding is required. It is only necessary to relatively unfold the two adjacent drive components 2 on both sides of the required opened curtain 3 to achieve partial shielding. Similarly, if shielding of more areas is required, more drive components 2 can be moved and other curtains 3 can be opened. The foundation pit canopy structure provided by the present application can complete the partial expansion or closing of the foundation pit canopy, and has good flexibility and adaptability.

[0041] Those skilled in the art will appreciate that, provided there is no conflict, the above preferred solutions can be freely combined and superimposed.

[0042] It should be understood that the above-mentioned embodiments are merely illustrative and non-restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
