Abstract
Description
Technical Field
[0001] The present application relates to the field of civil engineering technology, and in particular to a sliding device for a curved surface structure. Background Art
[0002] In order to avoid dust diffusion, noise nuisance and other problems at the construction site, a fully enclosed construction is usually adopted to avoid the influence of bad weather, and a curved structure is set above the excavation site for shielding (for example: construction canopy) to achieve the purpose of dust and noise reduction and green construction. In order to ensure that the construction process in the foundation pit can proceed smoothly, construction facilities such as overhead cranes, ventilation, and dust removal need to be placed in the foundation pit, and the excavated soil in the foundation pit needs to be continuously transported out of the foundation pit.
[0003] The boundary support of existing fixed curved surface structures is usually set in the direction of the surface normal. Under the self-weight load of the structure, its vertical load is decomposed into a component along the surface normal direction and a component along the surface tangent direction. However, for sliding curved surface structures, due to the existence of two orthogonal force components, when the curved surface structure slides horizontally along the plane, the slideway is subjected to bending and torsion, and the sliding deformation will seriously affect the horizontal sliding of the curved surface structure, and even cause the sliding structure to get stuck or derailed. At the same time, it also puts higher requirements on the design and production of the slideway. Utility Model Content

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.
[0026] refer to Figures 1 to 6 , the present application provides a sliding device for a curved surface structure, comprising:
[0027] The first sliding mechanism 300 is used to connect the opening and closing assembly 100 and the sliding assembly 200 so that the opening and closing assembly 100 can slide on the sliding assembly 200, and includes a bearing plate 301, a U-shaped slide groove 302, a support rod 303 and a rolling bearing 304; the bearing plate 301 is arranged on the outer top of the sliding assembly 200 and extends along the width direction of the sliding assembly 200, the U-shaped slide groove 302 is arranged on the upper surface of the bearing plate 301 and its opening is upward, the top of the support rod 303 is connected to the inner top of the opening and closing assembly 100, the bottom of the support rod 303 is provided with a groove 3031 opening downward, and the rolling bearing 304 is connected to the groove 3031 through the fixed shaft 500 and can slide along the length direction of the U-shaped slide groove 302. Among them, the first sliding mechanism 300 improves the stability of the movement process of the opening and closing assembly 100 and the sliding assembly 200. The bearing plate 301 can be connected to the outer top of the sliding assembly 200 by welding, and the U-shaped slide groove 302 can also be connected to the upper surface of the bearing plate 301 by welding. In addition, the support rod 303 bears part of the gravity of the opening and closing assembly 100, and plays a role in supporting the opening and closing assembly 100, and the rolling bearing 304 is a precision mechanical component that converts the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. The rolling bearing 304 is generally composed of four parts: an inner ring, an outer ring, a rolling element, and a cage. The inner ring is used to match the shaft and rotate with the shaft; the outer ring is used to match the bearing seat and play a supporting role; the rolling element is evenly distributed between the inner ring and the outer ring by means of the cage, and its shape, size and number directly affect the performance and life of the rolling bearing; the cage can make the rolling element evenly distributed, guide the rolling element to rotate and play a lubricating role. In the present application, the fixed shaft 500 penetrates the inner ring of the rolling bearing 304 and is connected to the two opposite side walls of the groove 3031. The upper half of the rolling bearing 304 is in the groove 3031, and the lower half is in the U-shaped slide groove 302 and its bottom end contacts the inner bottom surface of the U-shaped slide groove 302. There is a certain second preset distance between the two sides of the rolling bearing 304 and the two opposite inner side walls of the groove 3031. The second preset distance enables the outer ring of the rolling bearing 304 to roll freely under the action of external force. The second preset distance can be set according to actual needs, and the present application does not specifically limit it. The setting of the rolling bearing 304 reduces the friction between the support rod 303 and the U-shaped slide groove 302, making the sliding process of the opening and closing component 100 smoother.
[0028] The sliding device for a curved surface structure provided by the present application is provided with a first sliding mechanism 300 between an opening and closing component 100 and a sliding component 200, wherein a bearing plate 301 in the first sliding mechanism 300 is provided at the outer top of the sliding component 200 and extends along the width direction of the sliding component 200, and a U-shaped slide groove 302 is provided on the bearing plate 301, a support rod 303 is vertically provided at the inner top of the opening and closing component 100, and a groove 3031 is provided at the bottom end of the support rod 303, a rolling bearing 304 is fixed in the groove 3031 by a fixed shaft 500, and the rolling bearing 304 can slide along the length direction of the U-shaped slide groove 302, so that the opening and closing component 100 slides at the top of the sliding component 200. During the movement, the rolling bearing 304 slides in the U-shaped chute 302, and the support rod 303 moves synchronously with the rolling bearing 304. The support rod 303 carries the gravity load of the opening and closing assembly 100, so that the opening and closing assembly 100 is not affected by the tangential force as much as possible, but only by the normal force, and the normal force coincides with the gravity load of the opening and closing assembly 100 carried by the support rod 303, avoiding the bending and twisting of the opening and closing assembly 100 and the sliding assembly 200 during the horizontal sliding process, causing the sliding process to deviate, and even causing the phenomenon of being stuck or derailed, thereby improving the stability of the sliding process of the opening and closing assembly 100 and the sliding assembly 200. In addition, the provision of the rolling bearing 304 reduces the friction between the support rod 303 and the U-shaped chute 302, making the sliding process of the opening and closing assembly 100 smoother, thereby improving the sliding efficiency of the opening and closing assembly 100.
[0029] In some embodiments, reference Figure 1 The sliding device for the curved structure in the present application also includes multiple second sliding mechanisms 600; specifically, the structures of the multiple second sliding mechanisms 600 are the same as the structure of the first sliding mechanism 300, and the multiple second sliding mechanisms 600 are evenly distributed on both sides of the first sliding mechanism 300 and their top and bottom ends are respectively connected to the inner wall of the opening and closing component 100 and the outer wall of the sliding component 200.
[0030] In the above embodiment, the provision of multiple second sliding mechanisms 600 decomposes a portion of the gravity load of the opening and closing component 100, thereby reducing the gravity load borne by the first sliding mechanism 300, and the opening and closing component 100 is supported together by the two second sliding mechanisms 600 and the first sliding mechanism 300, so that the sliding process of the opening and closing component 100 is more stable and avoids deviation as much as possible so that it slides in a straight line direction.
[0031] In some embodiments, reference Figure 5, the upper sections of the two inner side walls of the U-shaped chute 302 in the present application are both provided with limit baffles 3021 through fasteners 700, each limit baffle 3021 extends along the length direction of the U-shaped chute 302, and the two limit baffles 3021 are separated by a first preset distance, which is greater than the diameter of the support rod 303 and less than the length of the fixed shaft 500. Among them, the first preset distance is only to allow the support rod 303 to move freely, while the fixed shaft 500 is always located in the U-shaped chute 302 and below the limit baffle 3021. The fastener 700 includes a fastening bolt and a nut, and the screw end of the fastening bolt sequentially penetrates the limit baffle 3021 and the side wall of the U-shaped chute 302 and is screwed with a nut, so as to fix the limit baffle 3021 on the inner side wall of the U-shaped chute 302.
[0032] In the above embodiment, the setting of the limit baffle 3021 enables the support rod 303 to slide along the length direction of the U-shaped groove 302, but the fixed shaft 500 can only be located in the U-shaped groove 302 and below the limit baffle 3021, so that the rolling bearing 304 is always in the U-shaped groove 302, and it is avoided as much as possible that the opening and closing component 100 swings upward or left and right due to external forces (such as wind), resulting in an unstable sliding process of the opening and closing component 100, thereby improving the stability of the sliding process of the opening and closing component 100.
[0033] In some embodiments, the height of the support rod 303 in the present application is 20cm-30cm, so that the support rod 303 can stably support the opening and closing component 100. The specific height value of the support rod 303 can be set according to actual conditions, and the present application does not make any specific limitations on it.
[0034] In some embodiments, the size of the supporting plate 301 in the present application is larger than the size of the U-shaped slide groove 302, which makes it easier to install the U-shaped slide groove 302 on the supporting plate 301. At the same time, the supporting plate 301 can better support and bear the own gravity of the U-shaped slide groove 302, making the installation of the U-shaped slide groove 302 more stable.
[0035] In some embodiments, there are multiple sliding assemblies 200 in the present application, and the multiple sliding assemblies 200 are spaced apart and distributed along the length direction of the foundation pit 400. The opening and closing assembly 100 is arranged between each two adjacent sliding assemblies 200, and the two sides of the opening and closing assembly 100 in the width direction are respectively slidably connected and fixedly connected to the two adjacent sliding assemblies 200. The multiple sliding assemblies 200 and the opening and closing assembly 100 arranged between each two adjacent sliding assemblies 200 are used to enclose the top of the foundation pit 400. Among them, the foundation pit 400 is opened on the construction site, and the opening and closing assembly 100 and the sliding assembly 200 are both slidably arranged across the top of the foundation pit 400, and the sliding assembly 200 can slide back and forth along the length direction of the foundation pit 400.
[0036] In the above embodiment, the foundation pit 400 is shielded by a plurality of sliding assemblies 200 spaced apart along the length direction of the foundation pit 400 and an opening and closing assembly 100 between every two adjacent sliding assemblies 200. At the same time, by sliding of the sliding assemblies 200 fixedly connected to the opening and closing assemblies 100 on both sides of the plurality of sliding assemblies 200 spaced apart along the length direction of the foundation pit 400, the opening and closing assemblies 100 fixedly connected to the sliding assemblies 200 are slid to the top of the sliding assemblies 200 slidably connected to the opening and closing assemblies 100, thereby shielding and opening the foundation pit 400, facilitating the placement of construction equipment into the foundation pit 400, and at the same time, outputting the soil in the foundation pit 400 from the foundation pit, thereby ensuring the normal progress of the construction process in the foundation pit 400.
[0037] In some embodiments, reference Figure 6 , the multiple opening and closing components 100 and the multiple sliding components 200 in the present application are all in an arc-shaped structure; wherein the opening and closing components 100 include a frame and a first flexible film layer covered on the frame, and the sliding components 200 include a grid and a second flexible film layer covered on the grid. Among them, the arc-shaped opening and closing components 100 and the arc-shaped sliding components 200 are wind-resistant and stable (the arc-shaped design can reduce the impact of wind on the canopy, making it more stable. Compared with designs of right angles or other shapes, the arc-shaped opening and closing components 100 and the arc-shaped sliding components 200 can reduce wind resistance, reduce the impact of wind on the opening and closing components 100 and the sliding components 200, and prevent the opening and closing components 100 and the sliding components 200 from being blown down or damaged by the wind), increase space and lighting (the arc-shaped design can increase the opening and closing components 100 and the sliding components The effective space of the component 200. Compared with a flat design, the arc-shaped opening and closing component 100 and the sliding component 200 provide more available space in the same area. In addition, the design of the arc-shaped opening and closing component 100 and the sliding component 200 can also make better use of natural light, provide better lighting effects), and self-cleaning performance (the arc-shaped design can help the opening and closing component 100 and the sliding component 200 to drain better, reduce the trouble of accumulated water and stains, improve the self-cleaning performance of the opening and closing component 100 and the sliding component 200, and extend the service life). In general, designing the opening and closing component 100 and the sliding component 200 into an arc shape can improve the stability, space utilization and aesthetics of the opening and closing component 100 and the sliding component 200, making them more suitable for various occasions.
[0038] In addition, the top of the foundation pit 400 is provided with slide rails 401 extending along the length direction of the foundation pit 400 on both sides of its width, and the bottom of the sliding assembly 200 is provided with pulleys 201 matching the slide rails 401. The sliding of the pulleys 201 in the slide rails 401 enables the sliding of the sliding assembly 200, thereby driving the opening and closing assembly 100 fixedly connected to the sliding assembly 200 to slide and overlap on the sliding assembly 200 slidably connected to the other side of the opening and closing assembly 100, thereby achieving the shielding and opening of the foundation pit 400, thereby meeting the actual construction needs in the foundation pit 400.
