Description

Technical Field

[0001] The invention relates to the technical field of cable or wire installation, and in particular to a cable shock-absorbing support and hanger. Background Art

[0002] During the use of wires and cables, they usually need to be installed through cable supports and hangers. During installation, the cables are usually wrapped or fixed through external fasteners. However, existing cable supports and hangers generally use a combination of angle steel, channel steel, some welded parts, and anchors. When the cable is vibrated by external forces, this type of support and hanger lacks corresponding shock absorption capabilities or measures, which can easily cause the cable sheath to fall off, and there is even a risk of breaking the core wire inside the cable.

[0003] The shock-absorbing support and hanger in the related art adopts a shock absorber arranged as a whole in the vertical direction to offset or control the impact of cable vibration. However, in actual use, the cables are not placed absolutely evenly on the support and hanger when they are installed. If the cables are biased to one side, the center of gravity of the cable support and hanger will shift, resulting in different load-bearing capacity of the shock absorber, and the stability of the shock absorption cannot be guaranteed, thus affecting the shock absorption effect. Summary of the invention

[0004] The present invention provides a cable shock-absorbing support and hanger to solve the problem that in actual use, the existing shock-absorbing support and hanger will have a center of gravity shift due to the cables not being placed absolutely evenly, resulting in uneven force bearing on the shock absorber and thus failure to ensure shock-absorbing stability.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] An embodiment of a cable shock absorbing support and hanger of the present invention is as follows Figures 1 to 9 shown.

[0029] A cable shock-absorbing support and hanger, such as Figure 1 As shown, it includes a bracket body 300, two groups of columns 200 and a plurality of shock absorbers 500. The two groups of columns 200 are respectively installed at the lower end of the building body 100, each group of columns 200 includes a plurality of columns, the plurality of columns are arranged in the vertical direction, and each two columns are arranged in parallel, the bracket body 300 includes two cross columns 450 and a plurality of cable struts 400; the two cross columns 450 are respectively installed on the two groups of columns 200, and the two cross columns 450 are parallel to each other, a plurality of shock absorbers 500 are respectively placed on the two cross columns 450, and the shock absorbers 500 are sequentially arranged in the extension direction of the cross columns 450, the two ends of each cable strut 400 are respectively installed on the shock absorber 500, the cable is placed on the cable strut 400, and the cable is fixed by external fasteners.

[0030] Specifically, in this embodiment, each group of columns 200 includes three columns. Further, the bracket body 300 is provided as at least one. Figure 1 As shown, in this embodiment, the bracket body 300 is set to three, and the number of the bracket body 300 can be set as needed. If the bracket body 300 is set to one, only one layer of cables is placed. When the bracket body 300 is set to multiple, multiple layers of cables can be installed.

[0031] like Figure 2 As shown, the shock absorber 500 includes a lower base 510 and an upper gland 520 slidably mounted on the lower base 510. The upper gland 520 can move up and down when the cable is placed on the cable support rod 400. Specifically, each cross column 450 is provided with a groove, and the lower end of the lower base 510 is fixedly mounted in the groove. Both ends of each cable support rod 400 are provided with a support arm, and the upper end of the upper gland 520 is fixedly mounted on the lower end of the support arm. A space is provided inside the upper gland 520 to allow the upper gland 520 to move up and down in the lower base 510. Therefore, when the cable is placed on the cable support rod 400, the cable support rod 400 can move up and down, thereby prompting the upper gland 520 to move.

[0032] like Figure 7 and Figure 8 As shown, the lower base 510 is provided with a control block 590, a trigger assembly and a plurality of damping plates 550; the plurality of damping plates 550 are sequentially arranged in the lower base 510 along a first direction, where the first direction refers to a horizontal direction, and the first direction is the extension direction of the crossbar 450, and the lower end of each damping plate 550 is mounted on the lower base 510 via a first spring 551, which is arranged in a vertical direction and always has a tendency to urge the damping plate 550 to move upward in a direction away from the lower base 510. Figure 4 As shown, a pressing block 521 is arranged in the upper pressing cover 520, and the pressing block 521 can contact with the damping plate 550 after the damping plate 550 pops up. Initially, a damping plate 550 pops up, so that the pressing block 521 contacts with the damping plate 550.

[0033] like Figure 8As shown, the control block 590 is installed in the lower base 510, and the control block 590 has a locked state and a moving state. In the locked state, the control block 590 does not move, and the initial control block 590 is in the locked state; in the moving state, the control block 590 moves, and a pushing member is provided in the lower base 510, and the pushing member is used to limit the shock absorbing plate 550 from popping out under the action of the first spring 551, and the movement of the control block 590 can make multiple shock absorbing plates 550 pop out in sequence along the first direction through the pushing member; the trigger component puts the control block 590 in the moving state when the deformation of the first spring 551 at the lower end of the popped-up shock absorbing plate 550 is greater than the first preset value, and puts the control block 590 in the locked state when the deformation of the first spring 551 at the lower end of the popped-up shock absorbing plate 550 is equal to the first preset value. The first preset value here refers to the deformation amount of the first spring 551 compressed by the upper pressure cover 520 after the cable is placed on the cable support rod 400, that is, if you want to keep the first spring 551 at a compression amount of 2 cm, then after the compression amount of the first spring 551 is greater than 2 cm, the trigger component can put the control block 590 in a moving state, and then make the shock absorbing plates 550 pop out one by one until the deformation amount of the first spring 551 at the lower end of the popped-out shock absorbing plates 550 is equal to the first preset value, that is, as more shock absorbing plates 550 pop out, the first spring 551 under each shock absorbing plate 550 shares less weight of the cable, so that the deformation amount of a single first spring 551 is smaller, until the deformation amount of the first spring 551 at the lower end of the popped-out shock absorbing plates 550 is equal to the first preset value, the trigger component prompts the control block 590 to return to the locked state, and the shock absorbing plates 550 that have not popped out will no longer continue to pop out.

[0034] When in use, first place the cable on the cable support rod 400, and fix the cable by external fasteners. Initially, one of the shock absorbing plates 550 pops out and contacts the pressure block 521 in the upper pressure cover 520. Since multiple shock absorbers 500 are placed on two crossbars 450 respectively, and one end of each cable support rod 400 is placed on the upper end of a shock absorber 500, that is, multiple shock absorbers 500 are independent of each other on the bracket body 300, when the cable is placed on the cable support rod 400, the shock absorber 500 can be adaptively adjusted according to the different placement positions of the cable on the cable support rod 400. Taking one of the shock absorbers 500 as an example, when the cable is placed on the cable support rod 400 where the shock absorber 500 is located, , the upper pressure cover 520 senses the weight of the cable, causing the upper pressure cover 520 to move downward, and the upper pressure cover 520 moves downward to press the shock-absorbing plate 550 in contact with the upper pressure cover 520, so that the first spring 551 is compressed. At the same time, when the deformation of the first spring 551 at the lower end of the pop-up shock-absorbing plate 550 is greater than the first preset value, the trigger component puts the control block 590 in a moving state, and the control block 590 moves through the pushing member to make multiple shock-absorbing plates 550 pop out in sequence along the first direction until the deformation of the first spring 551 at the lower end of the pop-up shock-absorbing plate 550 is less than or equal to the first preset value, so that the control block 590 is in a locked state.

[0035] In this embodiment, multiple shock absorbers 500 are respectively arranged between the cross column 450 and the cable support rod 400, so that the multiple shock absorbers 500 are independent of each other on the bracket body 300. When the cable is placed on the cable support rod 400, the shock absorber 500 can be adaptively adjusted according to the different positions of the cable on the cable support rod 400. By controlling the number of each shock absorbing plate 550 popping out, the first spring 551 at the lower end of the shock absorbing plate 550 is adapted to the weight of the cable on the cable support rod 400, ensuring that the deformation of the first spring 551 in the shock absorber 500 is basically consistent for cables in different positions. When the bracket body 300 vibrates, each shock absorber 500 has a stable shock absorbing effect, so that the cable shock absorbing support and hanger as a whole has better earthquake resistance.

[0036] In this embodiment, if Figure 7 As shown, the pusher includes a plurality of buckles 530, which are sequentially arranged in the lower base 510 along the first direction, and each buckle 530 is installed in the lower base 510 through a mounting member. Initially, a buckle 530 is arranged at the upper end of each shock absorbing plate 550 that has not been ejected, and the buckle 530 is used to limit the shock absorbing plate 550 from being ejected. A smooth rod 560 is arranged in the lower base 510, and the smooth rod 560 and the lower base 510 are key-grooved. Specifically, as shown in FIG. Figure 3 and Figure 6As shown, a reserved opening 512 is provided on the lower base 510, and the reserved opening 512 is circular. The smooth rod 560 is slidably installed in the reserved opening 512. A flat key is provided on the reserved opening 512, and a key slot for cooperating with the flat key is provided on the smooth rod 560, so that the smooth rod 560 can only move in the lower base 510 but cannot rotate in the lower base 510.

[0037] like Figure 8 and Fig. 9 As shown, the control block 590 is slidably mounted on the smooth rod 560 through a tension spring 591. When the control block 590 is in a moving state, the control block 590 is urged to move by the tension spring 591. Specifically, a through hole 594 is provided on the control block 590, and the smooth rod 560 passes through the through hole 594. The control block 590 and the smooth rod 560 are key-grooved, so that the control block 590 can only slide on the smooth rod 560.

[0038] A sliding column 595 is arranged on the control block 590. The movement of the control block 590 can drive the sliding column 595 to move along the first direction and pass through a plurality of buckles 530 in sequence. A sliding groove 532 is provided inside each buckle 530. When the control block 590 moves and drives the sliding column 595 to move, the sliding column 595 can move in the sliding groove 532, that is, the sliding column 595 cooperates with the sliding groove 532 during the movement, so that the buckle 530 moves in a direction away from the shock absorbing plate 550, thereby enabling the shock absorbing plate 550 to pop out.

[0039] Specifically, Fig. 9 The slide groove 532 is shown to connect the two end surfaces of the buckle 530 in the first direction, and the two ends of the slide groove 532 are the first end and the second end respectively. The control block 590 can sequentially pass through the first end and the second end of the slide groove 532 when moving along the first direction. The slide groove 532 is inclined, and the first end is arranged on the side close to the slide column 595 relative to the second end, and the distance from the first end to the center of the shock absorbing plate 550 is greater than the distance from the second end to the center of the shock absorbing plate 550. That is, in this embodiment, by setting the buckle 530 and the slide column 595 to cooperate with each other, when the control block 590 moves, the buckle 530 can be moved away from the spring plate, and during the movement of the control block 590, multiple shock absorbing plates 550 are ejected in sequence.

[0040] In this embodiment, if Figure 3 and Figure 5As shown, the mounting member is a partition 517, which is arranged along a first direction, and is fixedly mounted in the lower base 510. Each buckle 530 is slidably mounted on the partition 517. Specifically, a plurality of bayonet holes 516 are provided on the partition 517, and each buckle 530 is slidably mounted in a bayonet hole 516. The buckle 530 can slide in the bayonet hole 516 along a second direction, and the second direction is perpendicular to the first direction. When the control block 590 moves and drives the sliding column 595 to move, the sliding column 595 can move in the sliding groove 532, so that the buckle 530 moves in the bayonet hole 516 in a direction away from the shock absorbing plate 550, thereby enabling the shock absorbing plate 550 to pop out.

[0041] In another possible embodiment, the mounting member includes a plurality of connecting rods, which are arranged in a vertical direction. The upper end of each connecting rod is slidably mounted on the lower end of a buckle 530, and the lower end of each connecting rod is slidably mounted on the bottom wall of the lower base 510. The sliding direction of the connecting rod is the direction approaching or moving away from the shock absorbing plate 550.

[0042] In this embodiment, if Figures 5 to 9As shown, the trigger assembly includes a sensing plate 540, a first slide bar 511, a second slide bar 514, a trigger block 580 and a pressure bar 570. The upper end of the initial sensing plate 540 contacts the lower end of the pressure block 521. When the upper pressure cover 520 moves downward, the sensing plate 540 can be urged to move downward. The sensing plate 540 can drive the trigger assembly when the deformation of the first spring 551 at the lower end of the pop-up damping plate 550 is greater than a first preset value. The first slide bar 511 and the second slide bar 514 are both arranged in the vertical direction, and the first slide bar 511 and the second slide bar 514 are respectively installed in the lower base 510. The two ends of the sensing plate 540 are respectively It is slidably installed on the first slide bar 511 and the second slide bar 514, the trigger block 580 is installed on the first slide bar 511, the trigger block 580 is located below the sensing plate 540, an upper spring 581 is provided outside the first slide bar 511 and between the trigger block 580 and the sensing plate 540, the trigger block 580 is located above the lower base 510, and a lower spring 582 is provided between the trigger block 580 and the lower base 510, the upper spring 581 makes the sensing plate 540 contact with the upper pressure cover 520 at the initial stage. The pressure rod 570 is installed on the lower base 510 through the second spring 571. When the trigger block 580 moves downward, it can contact the pressure rod 570, thereby causing the pressure rod 570 to move downward. The control block 590 is provided with an upper one-way tooth 593. The lower one-way rack 572 is fixedly provided at the lower end of the pressure rod 570. The lower one-way rack 572 is used to mesh with the upper one-way tooth 593. Initially, the upper one-way tooth 593 meshes with the lower one-way rack 572, so that the control block 590 is in a locked state, limiting the movement of the control block 590. When the trigger block 580 moves downward, causing the pressure rod 570 to move downward, thereby causing the lower one-way rack 572 to move downward, so that the lower one-way rack 572 is disengaged from the upper one-way tooth 593, the control block 590 can move under the action of the tension spring 591, the control block 590 switches to the moving state, and drives the sliding column 595 to move.

[0043] Furthermore, two trigger assemblies are provided, and two pressure rods 570 of the two trigger assemblies are respectively fixedly connected to two ends of the lower one-way rack 572 .

[0044] Furthermore, if Figure 6As shown, a spiral protrusion is provided on the peripheral wall surface of the first slide bar 511, and a spiral hole for cooperating with the spiral protrusion is provided on the trigger block 580. When the induction plate 540 moves downward, the upper spring 581 is compressed to make the trigger block 580 move downward, and at the same time, the trigger block 580 rotates under the spiral cooperation with the first slide bar 511, further reducing the descending speed of the trigger block 580. When the cable shock-absorbing support and hanger is vibrated, since the vibration is back and forth and frequent, the spiral protrusion that can reduce the moving speed of the trigger block 580 is provided on the first slide bar 511, so that the trigger block 580 moves back and forth above the pressure rod 570 and will not contact the pressure rod 570. The adjustment of the trigger shock-absorbing plate 550 during cable installation is distinguished from the cable shock-absorbing support and hanger when it is vibrated, so as to prevent the trigger block 580 from triggering the pressure rod 570 due to the vibration of the cable shock-absorbing support and hanger.

[0045] In this embodiment, if Figure 6 and 9 As shown, a delay rack 513 is provided in the lower base 510, and a gear 592 for meshing with the delay rack 513 is rotatably provided on the control block 590. When the control block 590 moves, the gear 592 is driven to move, and the gear 592 meshes with the delay rack 513, so that the gear 592 rotates and moves, thereby reducing the overall moving speed of the control block 590 and preventing the shock-absorbing plate 550 from popping out too quickly.

[0046] In combination with the above embodiments, the specific working principle and working process are as follows: when in use, first place the cable on the cable support rod 400, and fix the cable by external fasteners. Initially, one of the shock absorbing plates 550 pops out and contacts the pressure block 521 in the upper pressure cover 520, providing a support for the cable when placing the cable. Since multiple shock absorbers 500 are respectively placed on two crossbars 450, and one end of each cable support rod 400 is placed on the upper end of a shock absorber 500, that is, multiple shock absorbers 500 are independent of each other on the bracket body 300, when the cable is placed on the cable support rod 400, the shock absorber 500 can be placed according to the different positions of the cable on the cable support rod 400. At the same time, adaptive adjustment is performed. Taking one of the shock absorbers 500 as an example, when the cable is placed on the cable support rod 400 where the shock absorber 500 is located, the upper pressure cover 520 senses the weight of the cable, causing the upper pressure cover 520 to move downward. The downward movement of the upper pressure cover 520 will compress the shock absorbing plate 550 in contact with the upper pressure cover 520, causing the shock absorbing plate 550 to be compressed. At the same time, the downward movement of the upper pressure cover 520 will prompt the sensing plate 540 in contact with the upper pressure cover 520 to move, that is, the pop-up shock absorbing plate 550 and the sensing plate 540 move downward at the same time.

[0047] Initially, the upper one-way tooth 593 is meshed with the lower one-way rack 572 to limit the movement of the control block 590. When the sensing plate 540 moves downward, the upper spring 581 is compressed, so that the trigger block 580 rotates and moves downward under the action of the upper spring 581. When the trigger block 580 moves downward to contact the pressure rod 570, the pressure rod 570 moves downward, thereby prompting the lower one-way rack 572 to move downward, so that the lower one-way rack 572 is disengaged from the lower one-way tooth. The control block 590 can move under the action of the tension spring 591, thereby driving the slide post 595 to move. The slide post 595 cooperates with the slide groove 532 during the movement and moves in the slide groove 532, thereby causing the buckle 530 to move away from the upper end of the damping plate 550, so that the damping plate 550 can be ejected one by one.

[0048] When the control block 590 moves, the gear 592 is driven to move, and the gear 592 engages with the delay rack 513, so that the gear 592 rotates and moves, reducing the overall movement speed of the control block 590, preventing the shock absorbing plate 550 from popping out too quickly, until the deformation of the first spring 551 at the lower end of the popped-out shock absorbing plate 550 is again less than or equal to the first preset value. That is, by controlling the moving speed of the control block 590, the control block 590 can be braked in time to avoid the situation where the deformation of the first spring 551 at the lower end of the popped-out shock absorber plate 550 is less than the first preset value and the control block 590 has already moved to make more shock absorber plates 550 pop out. In the process of the shock absorber plates 550 continuously popping out, the pressure rod 570 will gradually move upward with the multiple popped-out shock absorber plates 550, that is, gradually rebound. After the deformation of the first spring 551 at the lower end of the popped-out shock absorber plate 550 is less than the first preset value, the pressure rod 570 moves upward to make the lower unidirectional rack 572 mesh with the upper unidirectional tooth 593 again, thereby preventing the control block 590 from continuing to move, and further preventing other shock absorber plates 550 from continuing to pop out.

[0049] That is, during the cable installation process, when the cable is placed on the cable support rod 400, the shock absorber 500 can be adaptively adjusted according to the different positions of the cables on the cable support rod 400. By controlling the number of shock absorbing plates 550 popping out in each shock absorber 500, the first spring 551 at the lower end of the shock absorbing plate 550 is adapted to the weight of the cable on the cable support rod 400, ensuring that for cables in different positions, the deformation amount of the first spring 551 in the shock absorber 500 is basically the same. When the bracket body 300 vibrates, each shock absorber 500 has a stable shock absorbing effect, so that the cable shock absorbing support and hanger as a whole has better earthquake resistance.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
