The axial direction of the threaded rod and the sliding direction of the second protrusion are indicated by arrows in the figure; Figure 7 for Figure 6 A top view of the embodiment at the limiting portion.

[0018] The present application provides a standardized retractable frame supporting beam 110, comprising: A bracket, one end of which is provided with a top support 110 for lifting the supporting beam, and the other end of which is provided with a threaded rod 120; A support portion, one end of the support portion is grounded, and the grounded end of the support portion is provided with a first plane; a rotating member 310 rotatably connected to the support portion and rotating on the support portion around a first axis, wherein the first axis is perpendicular to the first plane; The movable ring 330 and the rotating part 310 are provided with a first protrusion, which protrudes out of the side wall of the support part along the first axis and is connected to the movable ring 330. A preset distance is provided between the first protrusion and the support part so that the first protrusion can rotate with the rotating part 310 and be held by hand. The distance from any point on the first protrusion to the first axis is less than 1 / 2 of the major diameter of the internal thread 331. The annular inner wall of the movable ring 330 is provided with an internal thread 331 matching the threaded rod 120. The threaded rod 120 is threadedly connected to the movable ring 330 through the internal thread 331 for spiral transmission, and the rotation of the movable ring 330 is converted into axial displacement of the threaded rod 120. The annular axis of the movable ring 330, the axis of the internal thread 331 and the first axis coincide with each other. Along the first axis, a telescopic distance is provided between the movable ring 330 and the support part.

[0019] Compared with the existing technology that cannot adjust the bracket height by itself, the standardized retractable frame support 110 beam provided by the present application drives the movable ring 330 to rotate synchronously through the rotating part 310 on the support part. The movable ring 330 drives its internal thread 331 to rotate but the axial movement is fixed and locked. Therefore, the threaded rod 120 threadedly connected to the internal thread 331 moves in a straight line along the axial direction to drive the support 110 to move quickly closer to and away from the ground. The height of the support 110 of the present application is adjusted to match beams of different heights to adapt to its flexible and changeable support needs.

[0020] In addition, because existing frame-type jacking beams 110 cannot adjust their height, workers are required to temporarily build scaffolding and climb to a higher place to install a temporary component to provide a support surface for supporting the jacking beam 110, and then to support the beam body. This is inconvenient to operate and has high safety risks. It is laborious to build and dismantle the scaffolding, difficult to install, and laborious to use, resulting in low work efficiency. The present application achieves height adjustment of the jacking beam 110 through a spiral transmission between the movable ring 330 and the threaded rod 120 (the former rotates and the latter moves axially), which improves the convenience of operation and improves safety while simplifying it.

[0021] In order to reduce the difficulty of rotating the movable ring 330 at a high place, the present application first sets a rotating part 310 (closer to the ground than the movable ring 330) on the support part, and makes the rotating part 310 close to the ground and the movable ring 330 away from the ground and close to the beam body rotate synchronously through the fixed connection and follow-up rotation of the first protrusion. The person holds the first protrusion or the rotating part 310 by hand and rotates it, prompting the upper movable ring 330 to rotate synchronously, and the spiral transmission makes the threaded rod 120 move axially in a straight line, constantly approaching or moving away from the side of the base close to the ground, thereby constantly approaching or moving away from the ground, so as to achieve the effect of adjusting the height.

[0022] The term "standardization" in the standardized retractable frame support 110 beam provided in this application refers to the fixed specifications and dimensions required for equipment components in the construction field, such as materials, dimensions of each component, load-bearing limits, range of telescopic values, and other specifications that remain unchanged. It cannot be understood that the equipment is standardized and cannot be telescoped. "Standardization" also means that the equipment production process follows unified process standards to meet the needs of general construction scenarios. This is to ensure that the performance of the equipment can be controlled, construction safety can be guaranteed, and construction efficiency can be improved. The flexible adjustment of the telescopic range and the standardization of the telescopic range jointly guarantee the versatility, safety and reliability of the equipment.

[0023] In some embodiments, the first protrusion is rod-shaped, and the rod-shaped first protrusion is a connecting rod 320. The length of the connecting rod 320 is aligned with the direction of the first axis, and its ends are respectively connected to the rotating member 310 and the movable ring 330. There are two or more connecting rods 320, and the two or more connecting rods 320 are distributed around the first axis. A gap is provided between adjacent connecting rods 320 to allow a person to grasp and rotate the rotating member 310 and the movable ring 330.

[0024] In some embodiments, the standardized retractable frame support 110 further includes a support leg 210. The support leg 210 has a lengthwise direction. One end of the support leg 210 along its lengthwise direction is rotatably connected to the sidewall of the support portion near the first plane. Along the first axis, a first spacing B is defined between the connection point of the support leg 210 on the support portion and the first plane. The first spacing B is less than a predetermined length L of the support leg 210 along its lengthwise direction. The support leg 210, the support portion, and the first plane together form a triangle. Furthermore, the support leg 210 is rotatably connected to the support portion via a damping shaft 211.

[0025] In some embodiments, the standardized retractable frame support 110 further includes a stopper 400. The stopper 400 is mounted on an end of the support base facing away from the first plane. The stopper 400 defines a retractable cavity opening away from the first plane. The opening of the retractable cavity is disposed opposite to the threaded rod 120. A predetermined gap is provided between the retractable cavity and the active trajectory of the threaded rod 120 to allow the threaded rod 120 to extend into / retract out of the retractable cavity along its own axial displacement.

[0026] In some embodiments, the telescopic cavity is provided with an elongated guide groove 410 for guiding and limiting the rotation of the threaded rod 120. A second protrusion 121 is provided on the radially outer wall of one end of the threaded rod 120, which faces away from the jack support 110 and passes through the movable ring 330. The second protrusion 121 extends into the guide groove 410. One end of the threaded rod 120 is slidably connected to the telescopic cavity via the second protrusion 121, with the sliding direction being consistent with the axial direction of the threaded rod 120. The connection between the second protrusion 121 and the telescopic cavity can strengthen the connection stability between the top bracket and the support portion, thereby improving the stability and load-bearing capacity of the jack support 110.

[0027] In some embodiments, the support portion is rod-shaped, with a fourth protrusion 222 formed along the widthwise sidewall of the rod at one end of the support portion closest to the first plane, forming the support member 220. The annular axis of the third protrusion 311 coincides with the longitudinal axis of the rod and also with the rotational axis of the rotating member 310. An annular groove 221 is formed on the side of the third protrusion 311 facing away from the first plane. The annular groove 221 opens away from the first plane, and the annular axis of the annular groove 221 coincides with the rotational axis of the rotating member 310. Along the first axis direction, the support 110, the movable ring 330, the first protrusion, the rotating member 310 and the third protrusion 311 are distributed in sequence. The third protrusion 311 is provided at one end of the rotating member 310 facing the first opening. The third protrusion 311 rotates with the rotating member 310. Along the first axis direction, the rotation trajectories of the annular groove 221 and the third protrusion 311 are relatively arranged. The third protrusion 311 extends into the annular groove 221 through the annular groove-shaped opening of the annular groove 221 away from the first plane, and is slidably connected to the annular groove 221.

[0028] By providing the bearing member 220 and the third protrusion 311, the present application increases the stability of the connection between the rotating member 310 and the support member, provides stable support for the rotating member 310, and improves its load-bearing capacity. The third protrusion 311 slides in the annular groove 221. The rotation trajectory of the third protrusion 311 following the rotation of the rotating member 310 coincides with its sliding trajectory in the annular groove 221, providing a certain radial constraint effect, which can reduce the risk of eccentricity.

[0029] Furthermore, a third annular protrusion 311 is provided on the side of the rotating member 310 facing the first plane. The annular axis of the third protrusion 311 coincides with the rotation axis of the rotating member 310, thereby enhancing the stability and uniformity of the connection between the rotating member 310 and the support member, providing stable and uniform support for the rotating member 310, and improving the bearing capacity of the rotating member 310.

[0030] In some embodiments, the support member 220 comprises two or more circular arc members capable of closing into a ring. Each arc member has two radially outwardly protruding arc ends. Multiple arc members are connected end to end to form a ring. Each arc member has an arc-shaped groove on one side of the ring along its axial direction. The arc-shaped grooves of the multiple arc members match, forming an annular groove 221 on one axial side of the ring. The outward protrusions at the arc ends of the arc members abut against and are bolted through the protrusions of two adjacent arc members protruding outside the ring, thereby connecting the two adjacent arc members. After the arc members are joined, an annular groove 221 is formed on the same side of the annular protrusion of the support member 220. The side with the annular groove 221 faces away from the first plane. The multiple arc members embrace the cylindrical support rod 200 with stirrups, increasing friction against axial displacement by radial compression along the first plane. This secures the support member 220 in place, providing stable support for the rotating member 310 via the annular groove 221.

[0031] In some embodiments, the end of the support 110 facing away from the threaded rod 120 is flat and plate-shaped. Preferably, the support 110 is entirely plate-shaped, with one side of the support 110 connected to the threaded rod 120 and the other side fixedly embedded with a non-slip pad 111. Preferably, the support 110 is a circular plate, with the center of the circle located on the axis of the threaded rod 120, and the axis of the threaded rod 120 being perpendicular to the plate surface.

[0032] Furthermore, a reinforcement member is provided at the connection between the top support 110 and the threaded rod 120 to form a closed triangle at the vertical connection between the plate-shaped top support 110 and the threaded rod 120, providing stable support. For example, two or more reinforcement members are provided at the connection between the top support 110 and the threaded rod 120. The reinforcement members are in the form of right-angled triangular plates, with the two sides of the right angle respectively attached to and fixedly connected to the side wall of the plate-shaped bottom of the top support 110 and the radial outer wall of the threaded rod 120. The two or more reinforcement members are distributed circumferentially around the axis of the threaded rod 120.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
