Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a rapid support device. Background Technology

[0002] In engineering fields such as mine roadways, tunnel construction, and building foundation pits, temporary support devices are crucial for ensuring construction safety. Traditional support structures typically employ fixed supports or manually adjustable jacks and hydraulic props, which have the following technical drawbacks: Low adjustment efficiency: Traditional support devices require adjusting the height or angle of each support point individually, making operation cumbersome and difficult to respond quickly to surrounding rock deformation or construction needs, affecting rescue and support efficiency. Insufficient stability: Single-point support or non-linkage adjustment may lead to uneven stress on the support plate, making it prone to deflection or instability, especially under dynamic loads (such as rock mass displacement), which exacerbates the risk. Poor adaptability: Existing support devices have a limited range of support angle adjustment, making it difficult to adapt to the support needs under complex geological conditions, such as rapid support for inclined roofs or areas of localized collapse. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rapid support device that solves the technical problem of limited support angle in existing support devices.

[0006] Base;

[0007] Support plate, rotatably mounted on the base;

[0008] At least one support member includes two telescopic rods and a support rod, wherein the support rods are spaced apart from the support plate, and the two telescopic rods are staggered between the support rods and the support plate in a vertical direction;

[0009] When the two telescopic rods extend or retract under the action of external force, they are used to link the support plate to rotate along the base.

[0010] Preferably, the support plate is provided with a first lug and a second lug, the support rod is movably provided with a first sleeve and a second sleeve, one end of the telescopic rod is connected to the first lug and the first sleeve respectively, and the other end of the telescopic rod is connected to the second lug and the second sleeve respectively.

[0014] Preferably, the base is provided with a receiving cavity, and a counterweight is detachably provided in the receiving cavity.

[0015] Preferably, a clearance groove is formed between the base and the support plate.

[0016] Compared with existing technologies, this utility model has the following advantages: 1.

[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0023] See Figures 1 to 3 This utility model provides a rapid support device, comprising:

[0024] Base 1;

[0025] Support plate 2 is rotatably mounted on the base 1;

[0026] At least one support member includes two telescopic rods 3 and a support rod 4, wherein the support rod 4 is spaced apart from the support plate 2, and the two telescopic rods 3 are staggered between the support rod 4 and the support plate 2 in a vertical direction;

[0027] When the two telescopic rods 3 extend or retract under the action of external force, they are used to link the support plate 2 to rotate along the base 1.

[0028] In this embodiment, the support plate 2 is mounted on the base 1 via a rotating mechanism (such as a hinge), allowing for dynamic adjustment of the support angle. A support member is provided on the base 1, consisting of a support rod 4 and two telescopic rods 3. The two telescopic rods 3 are connected between the support rod 4 and the support plate 2 in an alternating manner, forming a geometric linkage. When one telescopic rod 3 extends and the other telescopic rod 3 remains stationary, the support plate 2 can rotate counterclockwise around the base 1; conversely, the support plate 2 rotates clockwise around the base 1, enabling rapid adjustment of the support angle. The support rod 4 and the support plate 2 are spaced apart, providing both rigid support and allowing for rotational freedom. The linear movement of the telescopic rods 3 directly drives the support plate 2 to rotate, allowing for real-time changes in the support angle under external force. The staggered arrangement of the two telescopic rods 3 forms a torque balance, preventing the support plate 2 from deflecting and becoming unstable. At the same time, the compact structure reduces the space occupied.

[0029] The support plate 2 is provided with a first lug 5 and a second lug 6. The support rod 4 is movably provided with a first sleeve 7 and a second sleeve 8. The two ends of one telescopic rod 3 are respectively connected to the first lug 5 and the first sleeve 7, and the two ends of the other telescopic rod 3 are respectively connected to the second lug 6 and the second sleeve 8.

[0030] In this embodiment, the support plate 2 is provided with a first lug 5 and a second lug 6 at intervals, which are respectively used to hinge to one end of the two telescopic rods 3. At the same time, the support rod 4 is provided with a first sleeve 7 and a second sleeve 8 as connection points for the other end of the telescopic rods 3. One end of one telescopic rod 3 is hinged to the first lug 5 and the other end is hinged to the first sleeve 7. One end of the other telescopic rod 3 is hinged to the second lug 6 and the other end is hinged to the second sleeve 8. Through this connection method, the two telescopic rods 3 can be arranged vertically and vertically, and form a lever linkage effect during the extension and contraction process, thereby driving the support plate 2 to rotate around the base 1.

[0031] Both the first sleeve 7 and the second sleeve 8 include a first enclosing portion 81 and a second enclosing portion 82, which together form an installation cavity.

[0032] In this embodiment, to facilitate the movement of the first sleeve 7 and the second sleeve 8 on the support rod 4, both the first sleeve 7 and the second sleeve 8 include a first enclosing portion 81 and a second enclosing portion 82 connected to each other. When the first enclosing portion 81 and the second enclosing portion 82 are closed, they together form a mounting cavity for accommodating the support rod 4. Furthermore, the first enclosing portion 81 and the second enclosing portion 82 protrude outwards to form a limiting boss 9, which has multiple bolt holes 91. The first enclosing portion 81 and the second enclosing portion 82 both protrude outwards to form the limiting boss 9, and the limiting boss 9 has multiple bolt holes 91 for tightly fixing the first enclosing portion 81 and the second enclosing portion 82 together with bolts, thereby restricting further movement of the first sleeve 7 and the second sleeve 8.

[0033] The base 1 is provided with a plurality of positioning holes 12 for inserting positioning rods 13, and the positioning rods 13 are perpendicular to the base 1.

[0034] In this embodiment, to enhance the stability of the entire support device on the ground or other supporting surfaces and prevent slippage or overturning during operation, multiple positioning holes 12 are provided on the base 1. The positioning holes 12 are evenly distributed at different positions on the base 1, making it easy to select a suitable insertion point according to the site terrain. The positioning rod 13 is detachably inserted into the positioning hole 12 and is set perpendicular to the base 1. When the support device is placed on the ground or base, inserting the positioning rod 13 into the ground or other foundation structure can effectively enhance the anti-slip and anti-overturning capabilities of the entire device. The positioning rod 13 can be made of high-strength metal material, such as carbon steel or alloy steel, to withstand large shear and pull-out forces. When it is necessary to move the device, simply pull out the positioning rod 13 to complete the rapid transfer.

[0035] The base 1 is provided with a receiving cavity 11, and a counterweight is detachably provided in the receiving cavity 11.

[0036] In this embodiment, the receiving cavity 11 is located at the base 1, preferably in the middle of the base 1 or at a low center of gravity. The counterweight is detachably installed in the receiving cavity 11. Different weights of counterweights can be installed or replaced according to actual working conditions. The counterweight is preferably made of cast iron, steel plate, or other high-density materials to effectively increase the overall mass of the base 1. When not in use, the counterweight can be removed for easy transportation and storage. This method is suitable for operating scenarios with strong winds, sloping ground, or strong support reaction forces, and can significantly improve the stability and safety of the equipment.

[0037] A clearance groove 10 is formed between the base 1 and the support plate 2.

[0038] In this embodiment, a clearance groove 10 is provided between the base 1 and the support plate 2. The clearance groove 10 is located between the top edge of the base 1 and the root of the support plate 2. When the support plate 2 rotates and gets close to the base 1, the lower part of the support plate 2 avoids colliding with the base 1 through the clearance groove 10.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
