Technical Field

[0001] This application relates to the technical field of cable installation, and particularly relates to a cable clamp. Background Art

[0002] With the continuous development of the social economy and the increasing improvement of the scientific and technological level, the power industry in our country is also booming. As a device for transmitting electric energy or signals, a cable is usually made of one or more mutually insulated conductors and an outer insulating protective layer, and is used to transmit electric power or information from one end to the other. As an auxiliary device for fixing and laying cables, cable clamps play an important role in cable installation.

[0003] Regarding the above related technologies, since the existing cable clamps are generally fixedly installed on the inner top wall or inner bottom wall of the cable trench, and restricted by factors such as terrain and space, some cable trenches will be set to be relatively narrow, resulting in a narrow operating space for relevant personnel, and thus increasing the difficulty for relevant personnel to install cable clamps in the narrow cable trench. Therefore, it needs to be improved. Summary of the Invention

[0004] In order to facilitate relevant personnel to install cable clamps in narrow cable trenches, this application provides a cable clamp.

[0005] A cable clamp provided by this application adopts the following technical solutions: A cable clamp includes a mounting frame and a clamp body. The clamp body is arranged on the mounting frame, and the clamp body is used for clamping a cable. An extension frame is arranged on one side of the mounting frame, and the extension frame is used to abut against and be installed on the outer side wall of the cable trench. The extension frame is rotatably connected to the mounting frame. A fixing component is also arranged on the mounting frame, and the extension frame and the mounting frame are connected by the fixing component.

[0006] By adopting the above technical solutions, compared with the prior art, in which the cable clamp is integrally fixedly installed on the inner top wall or inner bottom wall of a narrow cable trench, resulting in a narrow operating space for relevant personnel and increasing the difficulty for relevant personnel to install the cable clamp in the narrow cable trench; in this application, through the setting of the extension frame, when the cable trench is too narrow, relevant personnel can rotate the extension frame and make the extension frame adhere to the outer side wall of the cable trench. And after fixing the extension frame and the mounting frame through the fixing component, relevant personnel can fix the extension frame on the outer side wall of the cable trench through fasteners such as screws and bolts, thus replacing the way of integrally installing the cable clamp on the inner top wall or inner bottom wall of the narrow cable trench in the prior art, effectively facilitating relevant personnel to install cable clamps in narrow cable trenches, reducing the installation difficulty of relevant personnel, and improving the installation efficiency.

[0007] Preferably, the clamp body includes an upper clamp, a lower clamp and a clamping piece, one end of the upper clamp is rotatably connected to one end of the lower clamp, the other end of the upper clamp is connected to the other end of the lower clamp through the clamping piece, the lower clamp is arranged on the mounting frame and movably connected to the mounting frame, and the mounting frame is also provided with an adjustment component for driving the displacement of the lower clamp.

[0008] By adopting the above-mentioned technical scheme, the setting of the clamp body and the adjustment component enables relevant personnel to drive the clamp body to move through the adjustment component, thereby changing the position of the clamp body to adapt to the specific position of the cable, and then to adapt to different cable installation position requirements, thereby increasing the scope of application of the present application, effectively facilitating the installation of cables by relevant personnel, and improving installation efficiency.

[0009] Preferably, abutment rollers are provided on both sides of the upper clamp and the lower clamp, the abutment rollers are rotatably connected to the corresponding upper clamp or lower clamp, and the side wall of each abutment roller is used to abut against the side wall of the cable.

[0010] By adopting the above technical solution and setting the abutment rollers, when the extension angle of the cable on both sides of the clamp body changes, the side walls of the cable can abut against the abutment rollers on the upper clamp and the lower clamp, thereby reducing the probability of excessive wear on the outside of the cable caused by the cable side walls continuously abutting against the intersection of the side walls of the upper clamp and the lower clamp due to excessive tension inside the cable, thereby effectively ensuring the service life of the cable.

[0011] Preferably, the lower clamp is also provided with a giving way mechanism, which includes a giving way frame and a linkage assembly. The giving way frame is slidably connected to the lower clamp, and the sliding direction is the direction away from the cable on the lower clamp. The abutment roller arranged on the lower clamp is rotatably connected to the giving way frame, and the upper clamp drives the giving way frame to slide through the linkage assembly.

[0012] By adopting the above technical scheme, the setting of the yielding mechanism makes it possible that when the upper clamp is in the open state, the abutting rollers on the yielding frames on both sides of the lower clamp are in a state away from the middle cavity of the lower clamp, so that it is convenient for relevant personnel to place the cable in the cavity in the middle of the lower clamp. At the same time, the existence of the linkage component makes it possible for the upper clamp to drive the yielding frame to slide through the linkage component during the process of rotating and gradually approaching the lower clamp, so that the abutting rollers on the yielding frame gradually approach the side wall of the cable, so that the abutting rollers abut against the side wall of the cable, thereby eliminating the need for relevant personnel to move the yielding frame additionally, realizing the linkage between the upper clamp and the corresponding yielding frame, and effectively facilitating the operation of relevant personnel.

[0013] Preferably, the linkage assembly includes an abutment frame and a transmission frame, the abutment frame is rotatably connected to the lower clamp, one end of the abutment frame is located on the displacement path when the upper clamp rotates, the other end of the abutment frame is rotatably connected to one end of the transmission frame, and the other end of the transmission frame is rotatably connected to the corresponding yield frame.

[0014] By adopting the above technical solution and the specific setting of the linkage assembly, the upper clamp can be abutted against the abutment frame, thereby pushing one end of the abutment frame to rotate, so that the other end of the abutment frame drives one end of the transmission frame to rotate, so that the other end of the transmission frame drives the corresponding yield frame to slide under the restriction of the sliding direction of the corresponding yield frame, thereby realizing the linkage between the upper clamp and the corresponding yield frame, which effectively facilitates the operation of relevant personnel.

[0015] Preferably, the clamp body further comprises a setting frame, the lower clamp is rotatably connected to the setting frame, the setting frame is slidably connected to the mounting frame, and the adjustment assembly is used to drive the setting frame to slide.

[0016] By adopting the above technical solution, the setting frame is set up so that when the parts of the cable located on both sides of the lower clamp are tilted, the cable can drive the lower clamp and the setting frame to rotate, thereby adapting to the change in the cable angle, thereby effectively reducing the probability of excessive internal tension of the cable due to tilting, thereby reducing the probability of cable breakage or wear, and ensuring the service life of the cable.

[0017] Preferably, the adjustment assembly includes an adjusting screw, a rotating frame and a locking piece, the adjusting screw is rotatably connected to the mounting frame, one end of the adjusting screw passes through the setting frame and is threadedly connected to the setting frame, the rotating frame is connected to the adjusting screw, and the rotating frame is connected to the mounting frame via the locking piece.

[0018] By adopting the above technical solution and the specific setting of the adjustment component, relevant personnel can rotate the rotating frame at the end of the mounting frame close to the outer side of the cable groove, so that the rotating frame drives the adjusting screw to rotate, causing the setting frame to move, thereby realizing the adjustment of the position of the setting frame to adapt to the specific position of the cable, effectively facilitating relevant personnel to adjust the position of the clamp body, and at the same time enabling relevant personnel to fix the rotating frame and the mounting frame through the locking member, thereby realizing the fixation of the position of the setting frame, effectively facilitating relevant personnel to fix the setting frame.

[0020] By adopting the above technical solution, the setting of the fixed component enables the extension frame to drive the connecting frame to slide through the driven frame when the extension frame rotates, so that the connecting frame can adapt to the change in the position of the extension frame, so that the connecting frame can continuously support the extension frame. At the same time, relevant personnel can fix the connecting frame on the mounting frame through the connecting piece to realize the fixation between the extension frame and the mounting frame, effectively ensuring the stability between the extension frame and the mounting frame.

[0021] Preferably, a reinforcement component is further arranged on the mounting frame. The reinforcement component includes a reinforcement frame, a linkage part and a fixing part. The reinforcement frame is slidably connected to the mounting frame, and the sliding direction of the reinforcement frame is different from the sliding direction of the connecting frame. The connecting frame drives the reinforcement frame to slide through the linkage part, and the reinforcement frame is connected to the cable trench through the fixing part.

[0022] By adopting the above technical solution, the setting of the reinforcement component enables the extension frame to rotate, so that when the connecting frame slides, the connecting frame can drive the reinforcement frame to slide through the linkage part, and one end of the reinforcement frame gradually moves away from the mounting frame, so that relevant personnel can fix the end of the reinforcement frame away from the mounting frame on the inner wall of the cable trench through the fixing part, effectively increasing the stability of the installation of the mounting frame.

[0023] Preferably, the linkage part includes a linkage frame. The linkage frame is rotatably connected to the connecting frame and rotatably connected to the reinforcement frame, and the rotation connection positions of the connecting frame and the reinforcement frame on the linkage frame are different.

After fixing the extension frame and the mounting frame through the fixing component, relevant personnel can fix the extension frame on the outer side wall of the cable trench through fasteners such as screws and bolts, thus replacing the prior art method of integrally installing the cable clamp on the inner top wall or inner bottom wall of the narrow cable trench, effectively facilitating the installation of the cable clamp by relevant personnel at the narrow cable trench, reducing the installation difficulty of relevant personnel, and improving the installation efficiency; 2.

One side wall of the extension frame 3 is arranged in contact with the outer side wall of the cable trench, and is fixedly connected to the cable trench by a plurality of fasteners such as screws or bolts.

[0034] Refer to Figure 2 and Figure 3 , the fixing component 4 includes a connecting frame 41, a driven frame 42 and a connecting piece 43. In the embodiment of the present application, the number of the driven frames 42 is set to two, and the two driven frames 42 are respectively located on both sides of the mounting frame 1 along its own width. One end of each driven frame 42 is rotatably connected to the extension frame 3 by a pin shaft, and the other end is rotatably connected to the connecting frame 41 by a pin shaft.

[0035] Refer to Figure 2 and Figure 3 , the middle of each connecting frame 41 is located inside the mounting frame 1, and is slidably connected to the mounting frame 1 by a slide rail, and the sliding direction is the length direction of the mounting frame 1. Both ends of each connecting frame 41 along the width direction of the mounting frame 1 extend outside the mounting frame 1, and are bent, and after being bent, are in contact with the outer side wall of the mounting frame 1.

[0036] Refer to Figure 1 and Figure 2 , in the embodiment of the present application, the connecting piece 43 is set as a screw. The bent part of the connecting frame 41 is fixedly connected to the mounting frame 1 by this screw. A plurality of holes for the screw to penetrate are also provided on the side wall of the mounting frame 1, so that the connecting frame 41 can be fixed at different positions, thereby adjusting the angle of the extension frame 3 to adapt to different cable trenches. In other embodiments, the connecting piece 43 can also be set as other fasteners such as bolts.

[0037] Refer to Figure 2 and Figure 3 , a reinforcing component 5 is also provided on the mounting frame 1. In the embodiment of the present application, the number of the reinforcing components 5 is set to two, and the two reinforcing components 5 are respectively located on both sides of the connecting frame 41 along the width direction of the mounting frame 1. Each reinforcing component 5 includes a reinforcing frame 51, a linkage 52 and a fixing member 53. Each linkage 52 includes a linkage frame 521.

[0038] Referring to Figure 1 and Figure 2 , one end of each reinforcing frame 51 is located inside the mounting frame 1 and is slidably connected to the mounting frame 1, and the sliding direction is the width direction of the mounting frame 1. The other end of each reinforcing frame 51 extends out of the mounting frame 1 and extends upward with a reinforcing portion 511. Each reinforcing portion 511 is in contact with the inner bottom wall of the cable trench. In the embodiment of the present application, the fixing member 53 is set as a screw, and the reinforcing portion 511 is fixedly connected to the cable trench through this screw. In other embodiments, the fixing member 53 can also be set as other fasteners such as bolts.

When the extension frame 3 rotates, the connecting frame 41 can drive the end of the reinforcing frame 51 to extend away from the mounting frame 1 through the linkage frame 521.

[0040] Referring to Figure 1 , Figure 2 and Figure 3 , in the initial state, that is, when the extension frame 3 is in the closed state, at this time, one side wall of the extension frame 3 abuts against the bottom of the mounting frame 1, and the other side wall is flush with the bottom side wall of the mounting frame 1. At this time, the connecting frame 41 is located on the side of its displacement path away from the extension frame 3, and at this time, one end of each reinforcing frame 51 located outside the mounting frame 1 is located on the side closest to the mounting frame 1. When the extension frame 3 rotates, causing the extension frame 3 to gradually open, the extension frame 3 drives the connecting frame 41 to slide in a direction closer to itself through the driven frame 42. During this process, the connecting frame 41 drives the reinforcing frame 51 to slide through the linkage frame 521, so that one end of the reinforcing frame 51 located outside the mounting frame 1 gradually moves away from the reinforcing frame 51, so that after the reinforcing frame 51 is fixed, the mounting frame 1 is more stable.

[0041] Referring to Figure 2 and Figure 4 , in the embodiment of the present application, the number of the fixture bodies 2 is set to two, and the two fixture bodies 2 are distributed along the length direction of the mounting frame 1. Each fixture body 2 includes a setting frame 21, a lower fixture 22, an upper fixture 23 and a clamping member 24. Each setting frame 21 is slidably connected to the mounting frame 1 through a slide rail, and the sliding direction is set to the length direction of the mounting frame 1. A avoiding hole 211 is penetrated through the side wall of each setting frame 21 along the length direction of the mounting frame 1, and the two avoiding holes 211 are arranged in a staggered manner.

[0042] Referring toFigure 2 Moreover, an adjusting assembly 6 is further provided on the mounting bracket 1. In the embodiment of the present application, the number of the adjusting assemblies 6 is set to two, and they are arranged in one-to-one correspondence with the setting brackets 21. Each adjusting assembly 6 includes an adjusting screw rod 61, a rotating bracket 62 and a locking member 63. One end of each adjusting screw rod 61 passes through the corresponding setting bracket 21, and is threadedly connected to the corresponding setting bracket 21.

[0043] Refer to Figure 2 One end of each adjusting screw rod 61 is rotatably connected to the mounting bracket 1 through a bearing, and one end of each adjusting screw rod 61 extends outside one end of the mounting bracket 1 close to the extension bracket 3. Each rotating bracket 62 is fixedly connected to one end of the corresponding adjusting screw rod 61 extending outside the mounting bracket 1 by welding. The side wall of each rotating bracket 62 is attached to the corresponding side wall of the mounting bracket 1.

[0044] Refer to Figure 2 In the embodiment of the present application, the locking members 63 are all set as a plurality of screws. One end of each screw passes through the corresponding rotating bracket 62 and reaches inside the mounting bracket 1, and is threadedly connected to the mounting bracket 1 to realize the fixation between the rotating bracket 62 and the mounting bracket 1. Correspondingly, a plurality of holes are also formed through the rotating bracket 62 for the screws to pass through, and threaded holes for inserting the corresponding screws are also formed on the side wall of the mounting bracket 1.

[0045] Refer to Figure 2 and Figure 4 The bottom of each lower clamp 22 is embedded in the corresponding setting bracket 21, and is rotatably connected to the corresponding setting bracket 21 through a bearing, and the rotation axis is the height direction of the mounting bracket 1, so that the lower clamp 22 can adapt to the change of the extension angle of the cable. One end of each upper clamp 23 is rotatably connected to one end of the corresponding lower clamp 22 through a pin shaft, so as to facilitate embedding the cable into the cavity between the lower clamp 22 and the upper clamp 23.

[0046] Refer to Figure 4 In the embodiment of the present application, each clamping member 24 is set as a plurality of bolts. The plurality of bolts are arranged at one end of the lower clamp 22 far from the end where it is rotatably connected to the upper clamp 23, so as to fix the ends of the lower clamp 22 and the upper clamp 23, thereby realizing the fixation of the upper clamp 23 and the lower clamp 22, so that the upper clamp 23 and the lower clamp 22 can clamp the cable.

[0047] Refer to Figure 4, each upper clamp 23 and each lower clamp 22 are provided with a plurality of abutting rollers 7 on both sides along the thickness direction thereof. In the embodiment of the present application, there is one abutting roller 7 on one side of each upper clamp 23, and the abutting roller 7 is provided at the top of the corresponding upper clamp 23. The abutting roller 7 at the top of each upper clamp 23 is rotatably connected to the corresponding upper clamp 23 through a pin shaft, and the bottom of the abutting roller 7 on each upper clamp 23 abuts against the cable between the upper clamp 23 and the lower clamp 22.

[0048] Reference Figure 4 , three abutting rollers 7 are arranged on one side of each lower clamp 22, and one of the three abutting rollers 7 on each side is located at the bottom of the lower clamp 22 and is rotatably connected to the lower clamp 22 through a bearing, and the top of the abutting roller 7 abuts against the cable between the upper clamp 23 and the lower clamp 22. The other two abutting rollers 7 are respectively located on both sides of the corresponding lower clamp 22 along its own length direction.

[0049] Reference Figure 4 Each lower clamp 22 is provided with a yielding mechanism 8. In the embodiment of the present application, the number of yielding mechanisms 8 on one side of each lower clamp 22 is set to two, and they are arranged one-to-one corresponding to the abutting rollers 7 located on both sides of the length direction of the corresponding lower clamp 22. Each yielding mechanism 8 includes a yielding frame 81 and a linkage assembly 82. One end of each yielding frame 81 is embedded in the corresponding lower clamp 22 and is slidably connected to the corresponding lower clamp 22, and the sliding direction is the length direction of the lower clamp 22.

[0050] Reference Figure 4 The abutting rollers 7 located on both sides of the length direction of the corresponding lower clamp 22 are rotatably connected to the corresponding clearance frame 81 through a pin, and the extension direction of the rotation axis is the height direction of the lower clamp 22. Each linkage assembly 82 includes an abutting frame 821 and a transmission frame 822. The middle part of each abutting frame 821 is rotatably connected to the corresponding lower clamp 22 through a pin. An abutting portion 8211 extends obliquely upward from one end of each abutting frame 821 away from the corresponding clearance frame 81. Each of the abutting portions 8211 extends toward the direction close to the corresponding clearance frame 81, and each abutting portion 8211 is located on the displacement path of the corresponding upper clamp 23.

[0051] Reference Figure 4 The other end of each abutment frame 821 is rotationally connected to one end of the corresponding transmission frame 822 through a pin shaft, and the other end of each transmission frame 822 is rotationally connected to the corresponding yielding frame 81 through a pin shaft to realize transmission between the abutment frame 821 and the yielding frame 81.

[0052] Reference Figure 4, at one end of each yielding frame 81 close to the corresponding abutting frame 821, a return spring 9 is provided, and the return spring 9 is a tension spring. Each return spring 9 is sleeved on the corresponding yielding frame 81, with one end fixedly connected to the corresponding yielding frame 81 and the other end fixedly connected to the corresponding lower clamp 22, so as to realize the reset of the yielding frame 81 through its own elastic force.

[0053] Referring to Figure 4 , in the initial state, that is, when the upper clamp 23 is in the open state, each yielding frame 81 is located at one end of its sliding path close to the corresponding abutting frame 821 under the elastic force of the corresponding return spring 9 to yield to the cable, facilitating the installation of the cable. When the cable is embedded in the cavity of the lower clamp 22 and the upper clamp 23 gradually rotates downward, the upper clamp 23 abuts against the abutting portion 8211 on the abutting frame 821, thereby driving the abutting frame 821 to rotate. At this time, the abutting frame 821 drives the corresponding transmission frame 822 to displace, and further enables the transmission frame 822 to drive the corresponding yielding frame 81 to slide, so that the yielding frame 81 gradually approaches the cable and the abutting roller 7 on the yielding frame 81 abuts against the outer wall of the cable.

[0054] The implementation principle of a cable clamp according to an embodiment of the present application is as follows: when the space in the cable trench is narrow, rotate the extension frame 3. At this time, the extension frame 3 drives the connecting frame 41 to slide through the driven frame 42, and the connecting frame 41 drives the end of the reinforcing frame 51 to gradually move away from the mounting frame 1 through the linkage frame 521. Then, the connecting frame 41 is fixed to the mounting frame 1 through the connecting member 43. After that, the side wall of the extension frame 3 close to the connecting frame 41 abuts against the outer side wall of the cable trench, and the bottom wall of the reinforcing frame 51 abuts against the inner bottom wall of the cable trench. Then, the extension frame 3 is fixed to the cable trench through screws, and the reinforcing frame 51 is fixed to the cable trench through the fixing member 53.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
