Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a combined enclosure for bridge foundation pit construction. Background Technology

[0002] Bridge foundation pit construction enclosures are crucial facilities for ensuring construction safety and environmental isolation. Traditional enclosures often use bolted or welded structures, which suffer from low installation efficiency and poor adaptability. Especially during the foundation pit excavation stage, uneven ground can easily cause adjacent enclosure units to tilt, requiring repeated adjustments to the bolt hole positions to achieve alignment, significantly increasing work time. Publication number CN222457053U discloses a quick-assembly modular construction enclosure device, including an angle adjustment component, a rotation adjustment component, and an installation limiting component. By setting up a dual adjustment mechanism and an oblique insertion assembly structure, the lower end of the device can be placed against uneven ground without leveling, thereby increasing construction speed. Furthermore, the load-bearing fixing structure of the device can still be adjusted after installation, increasing the tolerance for errors. In addition, the method of directly inserting and fixing lightweight partitions into the installation slots facilitates both installation and disassembly, further improving construction speed. However, this patent still has the following problems in practical use: When the above-mentioned devices are assembled as independent units, bolts are required for fixing, which is inconvenient to operate. When existing independent fences are assembled together, bolts are also required. Bolts are common connection structures in both cases. However, when there is an inclined ground surface to the adjacent fences, the alignment of the bolt holes will cause difficulties, making it difficult to install and fix them.

[0003] A combined enclosure for bridge foundation pit construction is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a modular enclosure for bridge foundation pit construction, in order to solve the problem that the above-mentioned devices mentioned in the background art require bolts for fixing when assembling independent units, which is inconvenient to operate. Existing independent enclosures also require bolts when assembled together. In both cases, bolts are common connection structures, but when the ground is inclined to the adjacent enclosures, the alignment of the bolt holes will cause difficulties, making it difficult to install and fix them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined enclosure for bridge foundation pit construction, comprising an enclosure body, wherein a first pillar and a second pillar are symmetrically fixedly connected to both sides of the enclosure body; The first and second pillars are provided with support components at their bottoms, and the first and second pillars are provided with connecting components on their sides.

A connecting column is fixedly connected to one end of the connecting rod that passes through the mounting plate. An inverted plate is fixedly connected to the side of the connecting column away from the connecting rod. A snap-fit ​​block is fixedly connected to the top and bottom of the inverted plate. The connecting plate has a central groove in the middle and two rows of snap-fit ​​grooves on the back.

[0006] Preferably, the mounting plate has a pair of through slots, and a rubber pad is provided between the two through slots. The rubber pad is fixedly embedded in the surface of the mounting plate, and an arc-shaped pad is fixedly connected to the surface of the rubber pad. The rotating shaft is eccentrically positioned with respect to the extrusion block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this modular enclosure for bridge foundation pit construction requires no bolts, is easy to operate, and can be quickly locked even if the enclosure is tilted. The specific details are as follows: 1. The connecting assembly, through its ingenious structural design, utilizes the synergistic action of components such as the mounting plate, connecting plate, connecting rod, and pressing block to achieve rapid fixing of adjacent enclosures. When used in combination, simply place the two enclosures side-by-side, rotate the mounting plate and connecting plate, and press down the curved handle to rotate the pressing block, causing the locking block to automatically engage with the locking groove. No bolts are required, making operation simple and convenient. Even when the two enclosures are tilted, locking can be easily achieved without complex alignment operations, significantly saving construction time and labor costs, improving construction efficiency, and providing strong support for the rapid progress of bridge foundation pit construction.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6The present invention provides a technical solution: a combined enclosure for bridge foundation pit construction, comprising an enclosure body 1, wherein a first support column 101 and a second support column 102 are symmetrically fixedly connected to both sides of the enclosure body 1. Support components 3 are provided at the bottom of the first pillar 101 and the second pillar 102, and connecting components 2 are provided on both sides of the first pillar 101 and the second pillar 102. The connecting assembly 2 includes a connecting plate 202 rotatably mounted on the outer side of the top of the first support column 101 and a mounting plate 201 rotatably mounted on the outer side of the top of the second support column 102. A pair of connecting rods 203 are slidably connected through the middle of the mounting plate 201. A rotating shaft 2031 is rotatably connected between the two connecting rods 203. A pressing round block 204 is fixedly connected to the outer side of the rotating shaft 2031. A curved handle 205 is fixedly connected to the outer side of the pressing round block 204. A connecting post 206 is fixedly connected to one end of the connecting rod 203 that passes through the mounting plate 201. An inverted plate 207 is fixedly connected to the side of the connecting post 206 away from the connecting rod 203. A snap-fit ​​block 208 is fixedly connected to the top and bottom of the inverted plate 207. The connecting plate 202 has a central groove 2021 in its middle and two rows of snap-fit ​​grooves 2022 on its back. When two different enclosures are used in combination, the two enclosure bodies 1 are placed side by side, and then the mounting plate 201 and the connecting plate 202 are rotated in sequence, so that the connecting column 206 in its initial state slides into the through groove 2011. When the mounting plate 201 and the connecting plate 202 are in a straight line, the curved handle 205 is pressed down, which drives the extrusion block 204 to rotate, thereby making the extrusion block 204 rotate in contact with the arc-shaped pad 2013. Because the rotating shaft 2031 lifts the extrusion block 204, the extrusion block 204 pulls the rotating shaft 2031 away from the mounting plate 201 during rotation, thereby driving the connecting rod 203 and the connecting column 206 to move. This causes the inverted plate 207 to drive the snap-fit ​​block 208 to snap into the snap-fit ​​groove 2022, allowing the two adjacent fences to be quickly fixed. Not only is it convenient to operate without the need for bolts, but also when the two fences are tilted due to the inclination of their bottom surfaces, there is no need to fine-tune the fences left and right to align the screw holes, and locking can be completed.

[0017] The mounting plate 201 has a pair of through slots 2011, and a rubber pad 2012 is provided between the two through slots 2011. The rubber pad 2012 is fixedly embedded in the surface of the mounting plate 201, and an arc-shaped pad 2013 is fixedly connected to the surface of the rubber pad 2012. The rotating shaft 2031 is eccentrically set with the extrusion block 204. When the extrusion block 204 rotates and pulls the connecting rod 203 to move in the through slot 2011, the snap-fit ​​block 208 will snap into the snap-fit ​​groove 2022. During the subsequent pulling process, the extrusion block 204 is completely snapped into the arc-shaped pad 2013 and the rubber pad 2012 is squeezed. The reaction force of the rubber pad 2012 is used to help fix the position of the extrusion block 204 after rotation, so that the rotation state of the extrusion block 204 is at a dead point and cannot be automatically reset.

[0018] The connecting rod 203 slides through the through groove 2011, and the arc-shaped pad 2013 is in contact with the arc-shaped side of the extrusion block 204.

[0019] The connecting post 206 movably passes through the central groove 2021, and the snap-fit ​​block 208 engages with the snap-fit ​​groove 2022. During the misalignment and alignment of the mounting plate 201 and the connecting plate 202, the connecting post 206 will slide into the central groove 2021. When the angles of the mounting plate 201 and the connecting plate 202 are adjusted to make them parallel, the snap-fit ​​block 208 will automatically align with a section of the snap-fit ​​groove 2022 and snap into place.

[0020] The curved grip 205 is located on the back of the mounting plate 201.

[0021] The support assembly 3 includes a support rod 301 that is rotatably connected to the back of the first pillar 101 and the second pillar 102, respectively. The bottom end of the support rod 301 is rotatably connected to a pad 302, and the pad 302 has a screw hole 303. By rotating the support rod 301, a bolt is passed through the screw hole 303 to connect it to the ground, thereby enabling the support rod 301 to provide additional support for the main body of the enclosure 1, further increasing its stability and making it difficult to overturn.

[0022] The first support column 101 and the second support column 102 are fixedly connected to the front of the binding rope 304; when the support component 3 is not in use, the binding rope 304 can be used to help store the support rod 301 and avoid interference.

[0023] Working principle: Before using this type of combined enclosure for bridge foundation pit construction, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, when using two different fences in combination, the two fence bodies 1 are first placed side by side. Then, the mounting plate 201 on the outer top of the second pillar 102 and the connecting plate 202 on the outer top of the first pillar 101 are rotated in sequence. At this time, the connecting column 206 in the connecting assembly 2 is in its initial state and slides into the through groove 2011 on the mounting plate 201. When the mounting plate 201 and the connecting plate 202 are in the same straight line, the curved handle 205 on the back of the mounting plate 201 is pressed down, causing the extrusion block 204 to rotate. Since the rotating shaft 2031 is eccentrically set with the extrusion block 204, and the rotating shaft 2031 has a lifting effect on the extrusion block 204, the rotation of the extrusion block 204 will pull the rotating shaft 2031 away from the mounting plate 201, thereby causing the connecting rod 203 and the connecting column 206 to move.

[0024] The connecting column 206 moves through the central groove 2021 on the connecting plate 202, and as it is pulled, the inverted plate 207 drives the snap-fit ​​block 208 to snap into the snap-fit ​​groove 2022 on the back of the connecting plate 202, thereby achieving rapid fixation of two adjacent fences.

[0025] During the process of the extrusion block 204 rotating and pulling the connecting rod 203, the extrusion block 204 will be completely inserted into the arc surface pad 2013 and squeeze the rubber pad 2012. The reaction force of the rubber pad 2012 is used to help fix the position of the extrusion block 204 after rotation, so that it is in a dead point and cannot automatically reset.

[0026] When the support assembly 3 is not in use, the support rod 301 is stored in the binding rope 304 fixed on the front of the first pillar 101 and the second pillar 102; when in use, the support rod 301 is rotated and bolts are passed through the screw holes 303 on the pad 302 to connect it to the ground to provide additional support for the main body of the enclosure 1.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
