Description

Technical Field

[0001] This utility model belongs to the field of foundation pit construction technology, and relates to an adjustable-width and movable anti-falling soil triangular cap device for foundation pit support beams. Background Technology

[0002] During foundation pit excavation, excavators spill soil onto the concrete support beams. This soil must be cleaned up regularly to prevent it from falling and injuring workers inside the pit. Because the support beams vary in width and are suspended in mid-air, there is a significant risk of workers falling during cleanup. Therefore, triangular cap devices are installed to prevent soil from falling onto the top of the concrete support beams, thus improving construction safety and efficiency.

[0003] Existing anti-soil triangular cap devices are placed directly on top of concrete support beams without any securing measures. In windy weather or when struck by excavators, they are prone to tipping over and rolling, reducing safety. Therefore, there is an urgent need for an adjustable-width, movable anti-soil triangular cap device for foundation pit support beams, adaptable to beams of varying widths and capable of rapid relocation as excavated soil spills. Summary of the Invention

[0004] In order to overcome the problems existing in the prior art, this utility model provides an adjustable-width and movable anti-falling soil triangular cap device for foundation pit support beams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Furthermore, the drive mechanism includes a bidirectional lead screw, a movable seat, and a rocker arm; the bidirectional lead screw is rotatably mounted below the support frame and has two threaded segments with opposite directions; two movable seats are provided, and each movable seat has a threaded hole, with the two movable seats respectively threadedly connected to the two threaded segments; rocker arms are provided on both sides of the movable seats, with one end of the rocker arm movably connected to the movable seat and the other end movably connected to the positioning plate.

[0008] Furthermore, the drive mechanism also includes a first transmission sprocket, a second transmission sprocket, a transmission chain, and a rocker wheel; the second transmission sprocket is fixedly connected to a bidirectional lead screw, and the transmission chain is respectively connected to the first transmission sprocket and the second transmission sprocket; the first transmission sprocket is rotatably mounted below the panel, and the rocker wheel is fixedly connected to the shaft of the second transmission sprocket.

[0009] Furthermore, the panel has an L-shaped cross-section, including two interconnected inclined surfaces; the support frame includes several parallel triangular frames, with the two sides of the triangular frames fixedly connected to the two inclined surfaces of the panel respectively; the sliding wheel is installed below the bottom edge of the triangular frame.

[0010] Furthermore, a hollow cover is fixedly installed below the bottom edge of the triangular frame, and the bidirectional lead screw passes through the cover and is rotatably connected to the cover through a bearing.

[0016] The beneficial effects of this utility model are:

[0017] (1) This utility model can prevent the device from tipping over by using a positioning plate to hold the crossbeam. The rocker wheel adjusts the distance between the two sets of positioning plates, thereby realizing the placement limit function of the device, significantly enhancing the lateral stability of the device, enabling it to better resist the tipping moment, thereby reducing the risk of tipping over. At the same time, it is convenient to adjust the position of the positioning plate so that it can be used for crossbeams of different widths, thus expanding the scope of application.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-2 As shown, this utility model embodiment provides an adjustable-width and movable anti-falling soil triangular cap device for foundation pit support beams, including a panel 1 (steel panel), a support frame 5, and a positioning structure 3.

[0027] The support frame 5 is fixedly connected to the inner wall of the panel 1, and a sliding wheel 6 is provided on the lower surface of the support frame 5. The positioning structure 3 includes two positioning plates 302 and a driving mechanism. The positioning plates 302 are slidably mounted on the support frame 5, and the two positioning plates 302 are parallel to each other. Under the action of the driving mechanism, the two positioning plates 302 can move linearly in a direction that moves closer to or further away from each other, and the moving direction of the positioning plates 302 is perpendicular to the moving direction of the panel 1. Rollers 303 are respectively provided on the inner sidewalls of the two positioning plates 302.

[0028] Panel 1 has an L-shaped cross-section, including two interconnected inclined surfaces (with an inclination angle of 45°). When excavators drop soil during digging, the soil will slide down the slope due to its own weight, avoiding accumulation on the concrete support beam, thus preventing soil from falling. A lifting ring 2 is fixedly installed on the top surface of panel 1, allowing the device to be suspended and transported by connecting ropes to the lifting ring 2.

[0029] In application, panel 1 is hoisted onto the foundation pit support beam. Sliding wheels 6 are positioned above and in contact with the support beam, while rollers 303 are located on both sides of the support beam. The drive structure drives two positioning plates 302 to move linearly, moving them towards the support beam until the rollers 303 on the inner wall of the positioning plates 302 contact the support beam, providing a clamping effect. The positioning plates 302 securely hold the crossbeam, thus stably placing the anti-falling soil triangular cap device on the foundation pit support beam, avoiding the safety risk of the device tipping over. Simultaneously, the anti-falling soil triangular cap can be flexibly moved using rollers 303 and sliding wheels 6 to the construction location. After construction is completed, the drive structure drives the two positioning plates 302 to move linearly away from the support beam, separating the anti-falling soil triangular cap device from the foundation pit support beam and hoisting it to another construction site.

[0030] like Figure 2 As shown, the drive mechanism includes a bidirectional lead screw 310, a movable seat 309, and a rocker arm 307. The bidirectional lead screw 310 is rotatably mounted below the support frame 5, and its distribution direction is consistent with the movement direction of the anti-falling soil triangular cap device. The bidirectional lead screw 310 has two threaded segments of the same length but opposite directions. Two movable seats 309 are provided, each with a threaded hole, and the two movable seats 309 are threadedly connected to the two threaded segments respectively. Rocker arms 307 are provided on both sides of the movable seats 309, and the two rocker arms 307 are mirror-symmetrical. One end of the rocker arm 307 is rotatably connected to the movable seat 309, and the other end is rotatably connected to the positioning plate 302. The structure distributed on the two threaded segments (movable seat 309 and rocker arm 307) is mirror-symmetrical about the centerline of the bidirectional lead screw 310.

[0031] When the bidirectional lead screw 310 rotates in the forward direction, the two movable seats 309 simultaneously move in opposite directions, driving the rocker arm 307 to move as well. The rocker arm 307 then moves the positioning plate 302 toward the foundation pit support beam, thereby adjusting the distance between the two sets of positioning plates 302 until the roller 303 on the inner wall of the positioning plate 302 contacts the support beam. When the bidirectional lead screw 310 rotates in the reverse direction, the two movable seats 309 simultaneously move in opposite directions, driving the rocker arm 307 to move as well. The rocker arm 307 then moves the positioning plate 302 away from the foundation pit support beam, adjusting the distance between the two sets of positioning plates 302, thus separating the anti-soil-falling triangular cap device from the foundation pit support beam.

[0032] As a further preferred embodiment of this utility model, the drive mechanism further includes a first transmission sprocket 304, a second transmission sprocket 306, a transmission chain 305, and a rocker wheel 301, as shown below. Figures 2-3 As shown. The second transmission sprocket 306 is fixedly connected to the end of the bidirectional lead screw 310. The transmission chain 305 is connected to the first transmission sprocket 304 and the second transmission sprocket 306 respectively. The first transmission sprocket 304 is rotatably mounted below the panel 1 (rotatably connected to the support frame 5). The central axis of the rocker wheel 301 is fixedly connected to the rotating shaft of the second transmission sprocket 306.

[0033] In application, the rocker wheel 301 is turned manually or electrically. The rocker wheel 301 drives the first transmission sprocket 304 to rotate, which in turn drives the second transmission sprocket 306 to rotate synchronously through the transmission chain 305. The second transmission sprocket 306 drives the bidirectional lead screw 310 to rotate, thereby realizing the motion adjustment of the positioning plate 302.

[0034] As a further preferred embodiment of this utility model, the support frame 5 includes three parallel and equidistant triangular frames. The two sides of the triangular frames are fixedly connected to the inner walls of the two inclined surfaces of the panel 1, respectively, and the bottom edge of the triangular frames is horizontal. Sliding wheels 6 are disposed below the bottom edge of the triangular frames, with two sliding wheels 6 mounted on the bottom edge of the triangular frames, and the two sliding wheels 6 are symmetrically distributed about the center line of the bottom edge.

[0035] As a further preferred embodiment of this invention, a hollow cover 311 is fixedly provided at the center of the lower surface of the bottom edge of each of the three triangular frames. The bidirectional lead screw 310 passes through the cover 311 and is rotatably connected to the cover 311 via a bearing 312 (ball bearing). This structure ensures the rotational stability of the bidirectional lead screw 310.

[0036] As a further preferred embodiment of this utility model, the positioning plate 302 has a door-shaped structure, including an integrally formed web and two vertical side plates (e.g., Figure 2(As shown). The positioning plate 302 is slidably connected to the bottom edge of the triangular frame (located at the center) via a guide frame 308. On one hand, the guide frame 308 is fixedly connected to the center of the web of the positioning plate 302; on the other hand, the guide frame 308 is slidably connected to the bottom edge of the triangular frame. Two rollers 303 are respectively provided on the inner walls of the two vertical side plates of the positioning plate 302.

[0037] As a further preferred embodiment of this utility model, four sets of traction structures 4 are also provided, arranged in pairs on the triangular frames distributed at both ends, for moving the remote traction device, such as... Figure 2 and Figure 4 As shown. Specifically, the traction structure 4 includes a rotating seat 401, a rope 402, and a movable hook 403. The rotating seat 401 (fixed or rotatable) is mounted on the outer side of the bottom edge of the triangular frame. The movable hook 403 is connected to the rotating seat 401 (rotatable or fixed). The end loop of the rope 402 is connected to the movable hook 403. The movable hook 403 can rotate flexibly as needed to adapt to different traction angles and directions, effectively avoiding jamming or tilting problems caused by improper angles or uneven force.

[0038] When the device is moved remotely, the operator first connects the rope 402 to the device via the moving hook 403 and uses the rope 402 to pull the device. At the same time, the sliding wheel 6 at the bottom of the device moves smoothly along the surface of the support beam under the action of the traction force, further reducing the resistance during the movement. Meanwhile, the roller 303 in the positioning structure 3 is close to the side of the support beam to ensure that the device will not detach from the support beam due to external forces during the movement. Since the moving hook 403 is rotatably connected to the triangular frame through the rotating seat 401, the rope 402 can maintain a certain degree of flexibility during the traction process, avoiding traction obstruction due to angle issues.

[0039] This utility model uses a hoisting ring 2, with ropes connected to the hoisting ring 2 for suspending and transporting the device. A positioning structure 3 clamps the crossbeam from both sides, preventing the device from tipping over. The positioning structure 3 can be adjusted according to the width of the crossbeam to accommodate different widths. Relying on the slope of the steel panel, the device slides down the slope by its own weight after the excavated soil falls, achieving the effect of preventing soil from falling. Through the traction structure, ropes are used to pull the device, enabling it to move quickly and safely.

[0040] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
