Description

Technical Field

[0001] This invention relates to the field of foundation pit protection support technology, and in particular to a portable support device for foundation pit edge protection. Background Technology

[0002] In various engineering construction projects, construction projects often face the dual pressures of tight schedules and heavy workloads. Especially when the construction access road is adjacent to the old road and there are multiple foundation pits distributed within the access road area, the balance between safety and efficiency becomes the core problem of construction management. These foundation pits are close to the traffic roads, with frequent pedestrian and vehicle traffic. If the edge protection is not installed in a timely and proper manner, it is very easy to cause safety accidents such as personnel falling and materials rolling, which will create major hidden dangers for the project construction.

[0003] Traditional edge protection often employs on-site welding and segmented erection, which is not only cumbersome and consumes a lot of manpower and resources, but also subject to site conditions, resulting in a long installation cycle and difficulty in adapting to tight construction schedules. In addition, there are some modular protective supports, but because these modular protective supports are prefabricated, their structure is fixed and cannot be adjusted according to actual needs, which leads to certain limitations in their actual use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a portable support device for the edge protection of foundation pits, thus achieving the advantage of applicability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a portable support device for edge protection of foundation pits, comprising: A vertical hydraulic rod, the output end of which is connected to a vertical pipe; The bracket assembly consists of two components, which are respectively mounted on the vertical hydraulic rod and the vertical pipe, for adjusting the protection angle. The support assembly includes a disc and a connecting plate. The disc is disposed at the opposite end of the vertical hydraulic rod and the vertical pipe. There are two connecting plates, both of which are rotatably disposed on the surface of the vertical hydraulic rod. The surface of the disk is provided with a slot; The other end of the connecting plate is provided with a column, the inner cavity of the column is provided with a first spring, the other end of the first spring is connected to a plug that penetrates and extends to the outside of the column, the other end of the plug is inserted into a slot, and the surface of the column is provided with a tube. The column is also provided with a limiting part to achieve the limiting and fixing after adjustment; A support column is provided at the bottom of the circular disk described at the bottom; A base assembly, which is disposed at the bottom of the support column, is used to adjust the levelness; The base assembly includes a box body disposed at the bottom of the support column, and two upright plates are disposed at the bottom of the box body, with a bottom plate rotatably disposed between the two upright plates; The housing is also equipped with an adjustment section to adjust the angle of the base plate, thereby adjusting the levelness.

[0006] Furthermore, the slot is a semi-circular arc-shaped slot, and there are multiple slots, which are distributed in a ring on the disk.

[0007] Furthermore, the insert is a rectangular block at one end of the inner cavity of the column, with a notch at the top, and the insert is a semi-circular arc at the other end of the column, with the size of one end of the arc surface matching the size of the slot. The surface of the insert slides and fits against the inner cavity surface of the column.

[0008] Furthermore, the limiting part includes a first lead screw rotatably mounted on the column, and a limiting block located in the inner cavity of the column is screwed onto the surface of the first lead screw.

[0009] Furthermore, one end of the first lead screw passes through and extends to the outside of the column, and a handle is provided at the end located outside the column. The surface of the limiting block slides and fits against the inner cavity surface of the column.

[0010] Furthermore, the surface of the base plate has two rectangular through holes.

[0011] Furthermore, the adjustment part includes four uprights and four lead screws, all of which are located at the top of the inner cavity of the box, and the second lead screw is rotatably mounted on the box. Two movable frames are slidably provided on the surface of the four uprights. The bottom of the movable frame extends through and to the outside of the box. A crossbar through the bottom plate is provided on the movable frame. A second spring sleeved on the surface of the upright is provided on the top of the movable frame. The surface of the second lead screw is screwed with a movable seat that fits against the top of the two movable bracket recesses.

[0012] Furthermore, the cross-section of the movable seat is an isosceles trapezoid, and the surface of the movable seat slides in contact with the surface of the housing.

[0013] Furthermore, a horizontal hydraulic rod is inserted into the insertion tube, and the output end of the horizontal hydraulic rod is connected to a crossbeam inserted into another insertion tube. Protective mesh is provided on the surface of the horizontal hydraulic rod and the crossbeam.

[0014] Furthermore, the surface of the insertion tube is provided with through holes, and the surfaces of the horizontal hydraulic rod and the crossbeam are provided with spring positioning beads corresponding to the through holes on the surface of the insertion tube.

[0015] The beneficial effects of this invention are reflected in: 1. In use, this invention comprises a support device consisting of a support assembly, horizontal hydraulic rods, crossbeams, and a protective net to protect the foundation pit. During use, the internal components of the support assembly allow for adjustment of the spacing between adjacent horizontal hydraulic rods and crossbeams, enabling them to be adjusted into straight, right-angle, or fan-shaped configurations, thus moving beyond traditional straight or right-angle supports to accommodate different applications. Furthermore, the extension and retraction of the vertical and horizontal hydraulic rods allow for adjustment of the height and width of the enclosure to accommodate different specifications of protective netting, further enhancing its applicability.

[0016] 2. In use, the present invention, through the base assembly, only requires rotating the second lead screw, which in turn drives the movable seat to move horizontally left and right. When the movable seat moves horizontally, it drives the base plate to rotate around the connection point between the base plate and the upright plate as the central axis through the movable frames on both sides. At this time, the base plate will tilt. This tilting of the base plate allows it to be placed on uneven ground while ensuring the verticality of the upper part of the support, which is beneficial for subsequent overall installation. By adjusting the levelness, it can be further adapted to different usage scenarios, thereby improving its applicability. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7 This invention discloses a portable support device for edge protection of foundation pits, comprising: A vertical hydraulic rod 1 is provided, and its output end is connected to a vertical pipe 2. By retracting the vertical hydraulic rod 1, the vertical pipe 2 can be moved up and down, thereby adjusting the protection height.

[0021] Support assembly 3, there are two support assemblies 3, which are respectively set on the vertical hydraulic rod 1 and the vertical pipe 2, to realize the adjustment of the protection angle; The support assembly 3 includes two discs 31 respectively disposed at the opposite ends of the vertical hydraulic rod 1 and the vertical pipe 2. The discs 31 have circular grooves, and the surface of the discs 31 has slots 32 located in the circular grooves. The slots 32 are arc-shaped, and there are multiple slots 32, which are distributed in a ring on the discs 31. The support assembly 3 also includes two connecting plates 33, each rotatably mounted on the surface of the vertical hydraulic rod 1. Each of the two connecting plates 33 has a column 34 at its other end. The connecting plates 33 allow the two columns 34 to revolve around the vertical hydraulic rod 1. The inner cavity of the column 34 is provided with a first spring 35, and the other end of the first spring 35 is connected to an insert block 36 that penetrates and extends to the outside of the column 34. The first spring 35 has a rebound effect, and the insert block 36 is a rectangular block located at one end of the inner cavity of the column 34. The surface of the insert block 36 slides against the surface of the inner cavity of the column 34. Through the above arrangement, the insert block 36 can only slide horizontally against the surface of the column 34. Meanwhile, the other end of the insert 36 is inserted into the slot 32, and the end of the insert 36 located outside the column 34 is semi-circular. The size of the end of the insert 36 located outside the column 34 is matched with that of the slot 32, and both are semi-circular. Therefore, when the column 34 rotates, under the action of the arc surface, the insert 36 will repeatedly retract into the column 34 and move out of the column 34. The column 34 is also equipped with a limiting part to achieve the limiting and fixing after adjustment; The limiting part includes a first lead screw 37 rotatably mounted on the column 34. A limiting block 38 located in the inner cavity of the column 34 is screwed onto the surface of the first lead screw 37. One end of the first lead screw 37 passes through and extends to the outside of the column 34, and a handle is provided at the end located outside the column 34. The handle facilitates the rotation of the first lead screw 37. At the same time, the surface of the limiting block 38 slides against the inner cavity surface of the column 34. Therefore, when the first lead screw 37 rotates, it only causes the limiting block 38 to move horizontally within the inner cavity of the column 34. By moving the limiting block 38, it can fit into the insert block 36. The limiting block 38 limits the insert block 36 inserted into the slot 32, preventing it from rotating further, thereby achieving the adjusted limiting fixation. The surface of the column 34 is provided with a tube 39. By inserting the corresponding insert block 36 on the column 34 into different slots 32, the orientation of the tube 39 can be adjusted so that the two tubes 39 on the same bracket assembly 3 can be in a straight line, a right angle, or a fan shape with a certain angle, thus making it no longer limited to a straight line bracket or a right angle bracket, but adjustable.

[0022] A horizontal hydraulic rod 6 is inserted into the insertion tube 39. The output end of the horizontal hydraulic rod 6 is connected to a crossbeam 7 inserted into another insertion tube 39. The horizontal hydraulic rod 6 and the crossbeam 7 together form the horizontal section of the enclosure. The horizontal hydraulic rod 6 and the crossbeam 7 are equipped with protective mesh 8. The protective mesh 8 is installed by a customized bracket and can be separated and disassembled after use. The horizontal hydraulic rod 6 can be extended and retracted to move the crossbeam 7, thereby adapting to the installation of protective mesh 8 of different specifications. The extension and retraction of the horizontal hydraulic rod 6 and the vertical hydraulic rod 1 can be used for the rapid assembly of edge protection for foundation pits of various sizes. They can be rotated between foundation pits of different sizes, and at the same time, they can avoid installation incoordination caused by site elevation differences, which can greatly improve material utilization and installation efficiency. The surface of the insertion tube 39 has through holes, and the surfaces of the horizontal hydraulic rod 6 and the crossbeam 7 are provided with spring positioning beads corresponding to the through holes on the surface of the insertion tube 39. The spring positioning beads are press-type spring positioning beads, and the size of the through holes is just right to fit the spring positioning beads. Through the above-mentioned cooperation, quick connection can be achieved during assembly, and the connection and fixation can be achieved without the aid of tools.

[0023] The base assembly 5 includes a box 51 disposed at the bottom of the support column 4. The bottom of the box 51 is provided with two upright plates 52, and a bottom plate 53 is rotatably disposed between the two upright plates 52. The surface of the bottom plate 53 is provided with two rectangular through holes. The housing 51 is also equipped with an adjustment part to adjust the angle of the base plate 53, thereby adjusting the levelness. The adjustment unit includes four uprights 54, each located at the top of the inner cavity of the housing 51. Two movable frames 55 are slidably mounted on the surfaces of the four uprights 54. The bottom of the movable frames 55 extends through and out of the housing 51. Under the action of the uprights 54, the two movable frames 55 can only move vertically up and down. The movable frame 55 is provided with a crossbar 56 that penetrates a rectangular through hole in the surface of the base plate 53, and a second spring 57 that is sleeved on the surface of the upright 54 is provided on the top of the movable frame 55. The adjustment unit also includes a second lead screw 58 rotatably mounted on the housing 51, wherein one end of the second lead screw 58 passes through and extends to the outside of the housing 51, and the outer end is connected to a handle, wherein the handle facilitates the rotation of the second lead screw 58. The surface of the second lead screw 58 is screwed with a movable seat 59 that fits against the top of the recesses of the two movable frames 55. The second spring 57 ensures that the recesses of the two movable frames 55 are always in contact with the surface of the movable seat 59. The cross-section of the movable seat 59 is an isosceles trapezoid, and the surface of the movable seat 59 slides against the surface of the housing 51. Therefore, when the second lead screw 58 rotates, it will drive the movable seat 59 to move horizontally. Since the movable seat 59 is an isosceles trapezoid, and the bottom of the concave part of the movable frame 55 is always in contact with the surface of the movable seat 59 under the action of the second spring 57, when the movable seat 59 moves horizontally, the movable frame 55 on one side will rise and the movable frame 55 on the other side will fall. At the same time, with the cooperation of the crossbar 56 and the rectangular through hole on the surface of the base plate 53, the base plate 53 can be driven to rotate around the connection point between the base plate 53 and the vertical plate 52 as the central axis. By placing the adjusted base plate 53 on the corresponding undulating ground, the verticality of the upper part, namely the vertical hydraulic rod 1, the vertical pipe 2 and the two support assemblies 3, can be ensured.

[0024] Through the above structural settings: 1. During use, the first lead screw 37 rotates, thereby moving the limiting block 38 away from the insert block 36. Since the insert block 36 is not limited, it can retract into the inner cavity of the column 34, allowing the column 34 to rotate. The rotation of the two columns 34 positions the two insert tubes 39 in different ways, including straight, right-angle, and fan-shaped states. After adjustment, the first lead screw 37 can be rotated in the opposite direction to make the limiting block 38 fit with the insert block 36. At this point, the insert block 36 cannot retract into the column 34, thus completing the adjusted limiting fixation. This adjustment allows the bracket assembly 3 to be no longer limited to a traditional straight or right-angle bracket, adapting to different usage situations. Furthermore, the extension and retraction of the vertical hydraulic rod 1 and the horizontal hydraulic rod 6 can adjust the height and width of the enclosure to accommodate different specifications of protective netting 8, further improving its applicability.

[0025] 2. In use, the rotation of the second lead screw 58 drives the movable seat 59 to move horizontally. When the movable seat 59 moves, it drives the movable frames 55 on both sides to rise and fall respectively. When the movable frames 55 on both sides rise and fall, they drive the base plate 53 to rotate around the connection point between the base plate 53 and the upright plate 52 as the central axis. By placing the adjusted base plate 53 on the corresponding undulating ground, the verticality of the upper part, namely the vertical hydraulic rod 1, the vertical pipe 2 and the two support components 3, can be ensured, which is conducive to the subsequent overall installation. By adjusting the levelness, it can be further adapted to different usage scenarios, thereby improving its applicability.
