Description

Technical Field

[0001] This utility model relates to the field of trench construction technology, and more specifically, to a trench support device. Background Technology

[0002] During open trenching for pipeline laying, slopes cannot be maintained due to site limitations. Therefore, shoring techniques are used to prevent trench wall collapse and potential safety accidents. Shoring techniques are generally applied to excavations below 3 meters, using timber, formwork, etc., as support tools. Both installation and dismantling of these tools rely on hoisting, which can easily lead to safety accidents. Therefore, there is an urgent need for a trench support device that is simple to install, convenient, and has a high safety factor. Utility Model Content

[0003] The technical problem to be solved by this utility model is that traditional support tools are inconvenient to operate and are prone to safety accidents during hoisting. Therefore, this utility model provides a trench support device that is simple and convenient to construct.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A trench support device includes a base, a telescopic bracket, and a support member. The base is fixed to the ground by insert-type foot anchors. The telescopic bracket includes a fixed column and a movable column. The bottom end of the fixed column is installed on one end of the base. The movable column can slide up and down on the fixed column. The support member with a reset function is disposed between the base and the telescopic bracket. One end of the support member is hinged to the base shaft pin, and the other end is hinged to the movable column shaft pin.

[0006] Preferably, an elastic element is provided between the telescopic bracket and the base.

[0007] Preferably, the movable column includes two parallel and spaced vertical bars, and a number of parallel and spaced horizontal bars are arranged between the two vertical bars, with the uppermost horizontal bar being rotatably and fixedly connected to both vertical bars.

[0008] Preferably, the support member is configured as a hydraulic damper.

[0009] Preferably, the support member is configured as a hydraulic piston rod.

[0010] Preferably, the telescopic bracket and the base are hinged by a pivot pin, and both ends of the support are detachably connected to the base and the telescopic bracket, respectively.

[0011] Preferably, the base has a through hole for inserting a foot, and the top side wall of the through hole has a raised tip.

[0012] The beneficial effects of this utility model are as follows: the support tools are spliced ​​together from bottom to top, with the uppermost support tool fixed on the telescopic bracket and the lowermost support tool in contact with the bottom wall of the trench. During the trench excavation process, the support plate sinks under its own weight and contacts the bottom of the trench. When the support tool sinks, it drives the movable column to slide downward. Afterward, the support tool separates from the movable column, and the movable column slides upward under the action of the support member to install the next support tool, thereby achieving efficient and safe installation of support tools.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0020] according to Figures 1-3As shown, a trench support device includes a base 1, a telescopic bracket 2, and a support member 3. The base 1 is fixed to the ground by insert-type foot 11. The telescopic bracket 2 includes a fixed column 21 and a movable column 22. The bottom end of the fixed column 21 is installed on one end of the base 1. The movable column 22 can slide up and down on the fixed column 21. The support member 3 with a reset function is disposed between the base 1 and the telescopic bracket 2. One end of the support member 3 is hinged to the base 1 with a pin, and the other end is hinged to the movable column 22 with a pin. The telescopic bracket 2 and the base 1 are hinged with a pin. The two ends of the support member 3 are detachably connected to the base 1 and the telescopic bracket 2, respectively.

[0021] according to Figures 1-3 As shown, during construction, the telescopic bracket 2 is raised to a vertical position to fix the support tool 5. Then, the two ends of the support member 3 are respectively hinged to the telescopic bracket 2 and the base 1. The support tool 5 is fixed to the movable column 22 by bolts or C-type buckles. The movable column 22 slides downward as the support tool 5 sinks. Subsequently, when the movable column 22 is freed from the weight of the support tool 5, it returns to its initial state under the action of the support member 3. After the construction is completed, the support member 3 is removed, and then the telescopic bracket 2 rotates with the hinge point between it and the base 1 as the center. The folded support device is also convenient for storage and transportation.

[0022] An elastic element 4 is provided between the telescopic bracket 2 and the base 1. The elastic element 4 can be a hollow rubber column or a compression spring. In this application, the elastic element 4 is set as a compression spring. The compression spring is used to assist the reset of the movable column 22. A protective bellows is provided on the outer sleeve of the compression spring.

[0023] according to Figures 1-3 As shown, the movable column 22 includes two parallel and spaced vertical rods 221, with several parallel and spaced horizontal rods 222 between the two vertical rods 221. The uppermost horizontal rod 222 is rotatably and fixedly connected to both vertical rods 221. The base 1 has a through hole for inserting the foot 11, and a pry bar is provided on the top side wall of the through hole. Because the uppermost horizontal rod 222 of the movable column 22 can rotate, the pull rope passes over the top of the uppermost horizontal rod 222, allowing manual hoisting of the support tool 5 in special circumstances. The pry bar facilitates the use of a pry bar to pull out the foot 11.

[0024] according to Figures 1-3 As shown, the support member 3 can be selected as a hydraulic damper according to construction needs, which is used to make the movable column 22 descend slowly and help it return to its initial state after the movable column 22 loses external force. It can also be selected as a hydraulic piston rod, which directly drives the movable column 22 to slide up and down, thereby causing the support tool 5 fixed on the movable column 22 to move up and down.

[0025] according to Figures 1-3As shown, the support tools 5 are assembled sequentially from bottom to top. The uppermost support tool 5 is fixed on the telescopic bracket 2, and the lowermost support tool 5 contacts the bottom wall of the trench. During the trench excavation, the support plate sinks under its own weight and contacts the bottom of the trench. When the support tool 5 sinks, it drives the movable column 22 to slide downward. After that, the support tool 5 separates from the movable column 22, and the movable column 22 slides upward under the action of the support member 3 to install the next support tool 5, thereby achieving efficient and safe installation of the support tool 5.
