Description

Technical Field

[0001] The present invention relates to the technical field of cable fixing devices, and in particular to an earthquake-resistant bridge frame for cable fixing. Background Art

[0002] An earthquake-resistant cable tray is a specially designed cable tray designed to improve the safety of cables and pipelines in natural disasters such as earthquakes. It uses a series of special designs and technologies to ensure that cables and pipelines can maintain their structural integrity even in an earthquake and reduce damage to the electrical system in the building. In a cable tray, the part used to place and support cables is usually called a "tray" or "ladder rack", and the specific name depends on its design. The tray is a trough-shaped structure with a closed bottom that can provide comprehensive support and protection for cables. It is suitable for occasions requiring a higher level of protection, such as corrosive gases and dusty places in industrial environments, or places with special protection requirements for cables. The tray is usually made of metal material and the surface may be galvanized or other anti-corrosion treated. The earthquake-resistant cable tray is composed of multiple rod-shaped components, and the connections between the parts are mostly connected by bolts. This connection method requires complex assembly of the earthquake-resistant cable tray when it is used, and the installation efficiency is low. Summary of the Invention

DETAILED DESCRIPTION

[0044] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] A seismic bridge for cable fixing, such as Figures 1-10 As shown, it includes a support frame 1; two connecting heads 2, which are symmetrically distributed and respectively arranged on both sides of the support frame 1; two fixing rods 3, which are symmetrically distributed and respectively fixed to adjacent connecting heads 2; four reinforcing rods 4, every two reinforcing rods 4 are rotatably connected to the same connecting head 2, and the two reinforcing rods 4 located at the same connecting head 2 are perpendicular to each other; four rotating members 5, which are rotatably connected to adjacent reinforcing rods 4.

[0046] The above scheme aims to increase the speed of installation of the device and reduce the space occupied by the device during storage and transportation. The support frame 1 is in direct contact with the tray, thereby providing support for the tray so that the tray can bear the weight of the cable. The connectors 2 are symmetrically distributed, so that the two sides of the support frame 1 are evenly stressed, avoiding deformation due to uneven stress, which may lead to loss of normal working ability. The fixing rod 3 is used to provide the main support for the entire device. It is connected to the bolts pre-fixed on the roof by a threaded connection. The fixing rod 3 is perpendicular to the roof during installation. The reinforcing rod 4 is tilted during installation. The rotating part 5 is fixed to the roof by bolts. The reinforcing rod 4, the fixing rod 3 and the roof together form a triangular structure to improve the structural strength of the device. The projections of the two reinforcing rods 4 on the same side on the horizontal plane are perpendicular to each other, so that the device has anti-sway capabilities in both the X-axis and Y-axis directions on the horizontal plane.

[0047] Furthermore, it also includes: two first limiting members 6 symmetrically distributed, both slidingly connected to the support frame 1, a first tension spring is provided between the first limiting member 6 and the support frame 1, and the connecting head 2 is provided with a first limiting groove that cooperates with the adjacent first limiting member 6.

[0048] In the above solution, the purpose is to achieve a quick connection between the support frame 1 and the connector 2. The two first limiting members 6 are both provided with inclined surfaces on their back sides. When the connector 2 is inserted into the support frame 1, the first limiting members 6 are pressed and moved, and the first limiting members 6 stretch the adjacent first tension springs. When the first limiting members 6 are aligned with the first limiting grooves, the first limiting members 6 are inserted into the first limiting grooves under the action of the first tension springs, thereby connecting the support frame 1 and the connector 2.

[0049] Furthermore, it also includes: four first sliding columns 7, the reinforcement rod 4 is provided with a first sliding groove 41, and the first sliding columns 7 are slidably connected to the adjacent first sliding groove 41; four friction blocks 8 are respectively fixed to the adjacent first sliding columns 7, and the friction blocks 8 are frictionally matched with the adjacent connecting heads 2.

[0050] In the above scheme, the reinforcement rod 4 and the connector 2 are fixed to enhance the stability of the device. A first slide groove 41 is provided on the side of the reinforcement rod 4 adjacent to the adjacent connector 2. The first slide groove 41 and the first sliding column 7 are both cylindrical to enhance the sealing between them. A ceramic friction material layer is provided on the side of the friction block 8 adjacent to the adjacent connector 2 to increase the friction between the friction block 8 and the connector 2 and improve the stability between the two.

[0051] Furthermore, it also includes: four sliding plates 9, which are slidably connected to adjacent first sliding grooves 41 respectively, a first spring and a thin rope are arranged between the sliding plate 9 and the adjacent first sliding column 7, and a second tension spring is arranged between the sliding plate 9 and the adjacent reinforcing rod 4.

[0052] In the above scheme, the friction block 8 is designed to apply pressure to the connector 2. The first spring between the sliding plate 9 and the first sliding post 7 is initially compressed, so that the friction block 8 exerts a high pressure when in contact with the connector 2. The thin rope between the sliding plate 9 and the first sliding post 7 is used to enable the sliding plate 9 to pull the first sliding post 7 back to its original position. The second tension spring is used to return the sliding plate 9 to its original position.

[0053] Furthermore, it also includes: a second sliding column 10, which has several, the rotating member 5 is provided with a second slide groove 51, and the several second sliding columns 10 are respectively slidably connected to the adjacent second slide grooves 51, and the second sliding column 10 is slidably connected in the second slide groove 51, the first slide groove 41 and the second slide groove 51 are both filled with liquid, and the first slide groove 41 and the adjacent second slide groove 51 are connected; there are four extrusion plates 11, which are respectively fixed to the adjacent second sliding columns 10.

[0054] In the above scheme, the bolts securing the rotating member 5 are used to cause the friction block 8 to squeeze the connector 2. Two symmetrically distributed second chutes 51 are provided on one rotating member 5, ensuring uniform force when the bolts squeeze the extrusion plate 11. The liquid mentioned here and below is hydraulic oil used for transmission. When the second sliding post 10 moves upward, it presses the liquid in the second chutes 51 into the first chutes 41. The increased liquid in the first chutes 41 pushes the sliding plate 9 to move. The sliding plate 9, in turn, pushes the first sliding post 7 via the first spring, which in turn pushes the friction block 8 to squeeze the connector 2.

[0055] Working process: When this device needs to be used to support the cable tray, first insert the two connecting heads 2 into the support frame 1. During the process of inserting the connecting head 2 into the support frame 1, the first limiting member 6 is squeezed, and the first limiting member 6 moves and stretches the first tension spring. Then, the first limiting member 6 is inserted into the first limiting groove of the connecting head 2 under the action of the first tension spring, and then the two fixing rods 3 are fixed on the pre-set bolts. After the fixing rods 3 are fixed, the reinforcing rod 4 is rotated, and the reinforcing rod 4 drives the rotating part 5 to move so that the rotating part 5 is aligned with the pre-set bolts, and then connected. Finally, the tray and the support frame 1 are fixed with angle irons and bolts.

[0056] Furthermore, it also includes: two symmetrically distributed clamping plates 12, both of which are slidably connected to the support frame 1, and a third tension spring is provided between the opposing sides of the two clamping plates 12 and the support frame 1.

[0057] In the above solution, the purpose is to quickly fix the pallet, so as to further improve the installation efficiency and disassembly efficiency of the device. The clamping plate 12 clamps and fixes the pallet through the tension of the third tension spring.

[0058] Furthermore, it also includes: a second limiting member 13, which is slidably connected to the support frame 1, a second spring is provided between the second limiting member 13 and the support frame 1, the second limiting member 13 is provided with a plurality of second limiting grooves, and the clamping plate 12 is limitedly matched with the adjacent second limiting grooves.

[0059] In the above solution, the clamping plate 12 is limited in position, thereby making it easier for the clamping plate 12 to clamp the pallet. The second limiting member 13, under the action of the second spring, limits the clamping plate 12 so that the clamping plate 12 is limited by the second limiting member 13 when it is pulled apart, thereby facilitating the clamping plate 12 to clamp the pallet.

[0060] Furthermore, the system further includes: two buffer members 14 symmetrically distributed and respectively slidably connected to adjacent clamping plates 12 , and fourth tension springs are respectively provided between the back sides of the two buffer members 14 and the adjacent clamping plates 12 .

[0061] The above solution aims to provide a certain degree of wiggle tolerance for the pallet. The buffer 14 consists of a large flat plate, a small flat plate, and a straight rod. The large flat plate of the buffer 14 is equipped with a rubber pad to reduce friction between the buffer 14 and the pallet, thereby extending the service life of the buffer 14 and the pallet. A fourth tension spring is installed between the small flat plate of the buffer 14 and the clamping plate 12. The clamping plate 12 drives the buffer 14 to move, bringing it into contact with the pallet, thereby clamping the pallet.

[0062] Furthermore, it also includes: a third limiting member 15, which has several parts and is slidably connected to the adjacent clamping plates 12, a third spring is provided between two adjacent third limiting members 15, and the support frame 1 is provided with several third limiting grooves, and the third limiting member 15 is limitedly matched with the adjacent third limiting grooves.

[0063] The above solution aims to secure the clamping plate 12, preventing it from being squeezed and moved by the pallet. Two third stoppers 15 are slidably connected to each clamping plate 12, ensuring a more even force distribution on both sides of the clamping plate 12 and preventing damage caused by stress concentration due to unidirectional force. When disassembling the device, pressing the two third stoppers 15 compresses the third spring and separates them from the third stopper slot, allowing the two clamping plates 12 to move in opposite directions.

[0064] Furthermore, it also includes: extrusion blocks 16 , the number of which is the same as the number of the third limiting members 15 , the extrusion blocks 16 are fixed to the adjacent buffer members 14 , and the extrusion blocks 16 are extrusion-fitted with the adjacent third limiting members 15 .

[0065] In the above solution, the third limiting member 15 is kept separated from the third limiting groove. The small flat portion of the buffer member 14 is fixed with two extrusion blocks 16, and the two extrusion blocks 16 are provided with inclined surfaces on their facing sides, thereby squeezing the third limiting member 15 to move.

[0066] Working process: After the assembly of this device is completed, the buffer part 14 drives the extrusion block 16 to squeeze the third limit part 15 under the action of the fourth tension spring, so that the third limit part 15 is separated from the third limit groove, and then the two clamping plates 12 are pulled in reverse so that the support frame 1 is located below the pallet, and then the support frame 1 is moved upward, the second limit part 13 contacts the pallet, and the second limit part 13 is squeezed downward by the pallet and compresses the second spring, and the second limit part 13 is separated from the clamping plate 12. The clamping plate 12 drives the buffer part 14 to move and clamp the pallet under the action of the third tension spring. The buffer part 14 moves relative to the clamping plate 12 and stretches the fourth tension spring. The buffer part 14 drives the extrusion block 16 to move, so that the extrusion block 16 is separated from the third limit part 15. The third limit part 15 is inserted into the third limit groove under the action of the third spring, thereby completing the fixation of the pallet by this device.
