Description

Technical Field

[0001] The invention relates to the technical field of cable fixing, in particular to a fixing frame capable of adjusting the height of a cable clamp. Background Art

[0002] In hydropower plants, cable brackets play a vital role. They not only support and protect cables, ensuring the safety and stable operation of the cable system, but also need to have certain corrosion resistance and water immersion resistance in view of the special environmental requirements of hydropower plants. Traditional cable brackets are mostly welded with angle steel. The cables are easily worn due to friction on the brackets, and are easy to slip during the laying process, which affects the installation efficiency and increases the labor intensity. In order to solve these problems, many modern hydropower plants have conducted further research on cable clamps to ensure effective clamping and limiting to prevent cables from slipping. However, most hydropower plants have ignored how to adjust the height of the cable clamps while solving this problem.

[0003] The height adjustment of the cable clamp can meet the diverse needs of cable laying in different scenarios. This not only reduces the friction between the cable and the cable clamp, but the height-adjustable cable clamp can adapt to the laying requirements of different heights and improve the flexibility and efficiency of construction. In addition, the height adjustment function of the cable fixing frame can prevent the cable from hanging on the ground when laying, reduce cable damage, and improve the laying effect. In addition, the height adjustment design also helps to adapt to cables of different weights, ensure the stability and safety of the cables during laying, and reduce damage caused by cable sagging or uneven tension.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a fixing bracket capable of adjusting the height of the cable clamp. Before fixing, a test can be performed to ensure that the installation height meets the working requirements.

[0032] Specifically, the bearing assembly 100 includes an outer frame 101; and the adjusting assembly 200 includes an inner frame 201 movably disposed in the outer frame 101; and the wire fixing assembly 300 includes a fixing frame 301 detachably disposed in the inner frame 201 and a wire clamp 301a disposed outside the fixing frame 301. The inner frame 201 in the adjusting assembly 200 can be vertically raised and lowered in the outer frame 101, and when the fixing frame 301 is inserted into the inner frame 201, the wire clamp 301a will change height along with the inner frame 201.

[0033] Among them, before determining the specific height of the wire fixing component 300, the wire fixing component 300 can still be pulled out after being inserted into the adjusting component 200 for height testing, and the wire fixing component 300 and the adjusting component 200 are not restricted in this process; when the specific height of the wire fixing component 300 is determined, the wire fixing component 300 is rotated and inserted into the adjusting component 200 again, at this time the adjusting component 200 will be fixed in the outer frame 101, and the wire fixing component 300 is fixed in the adjusting component 200 and cannot be pulled out.

[0034] Example 2, reference Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, a fixing method of an adjustment component 200 is provided.

[0035] Specifically, the outer wall of the outer frame 101 is provided with screw holes 101b, and a plurality of connecting plates 102 are distributed in a linear array on one side of the outer wall of the outer frame 101. A first connecting through hole 102a is formed through the outer wall of each connecting plate 102, and a second connecting through hole 101a which is horizontal to each first connecting through hole 102a is formed through the other side of the outer wall of the outer frame 101. The more the number of the first connecting through holes 102a and the second connecting through holes 101a is provided, the more precise the height adjustment of the adjustment assembly 200 is.

[0036] A fixed cylinder 201a is arranged in the inner frame 201, and a transmission channel 201a-2 is formed through the outer wall of the fixed cylinder 201a. A transmission gear 202 is arranged in the inner frame 201, and the outer wall of the transmission gear 202 extends into the fixed cylinder 201a by passing through the transmission channel 201a-2. A fastener 203 is arranged on the lower end surface of the inner frame 201, and the fastener 203 includes a clamping plate 203c movably connected to the first connecting through hole 102a, and the clamping plate 203c can only move in the horizontal direction along the end of the inner frame 201. Figure 3 When the two clamping plates 203c are displaced and respectively inserted into the first connecting through hole 102a and the second connecting through hole 101a, the height of the inner frame 201 is fixed immediately.

[0037] A transmission shaft 202a is provided in the axial direction of the transmission gear 202, and one end of the transmission shaft 202a extends to the lower end surface of the inner frame 201 and is provided with a first pulley 202a-1, and the fastener 203 also includes a second pulley 203a, and the outer wall of the second pulley 203a and the first pulley 202a-1 is sleeved with a chain 203a-1. If the transmission shaft 202a rotates, the first pulley 202a-1 will rotate the second pulley 203a through the chain 203a-1.

[0038] A transmission disc 203b is provided in the axial direction of the second pulley 203a, and a transmission groove 203b-1 is formed through the outer wall of the transmission disc 203b, a transmission column connected to the transmission groove 203b-1 is provided at the end of the clamping plate 203c, and a warning end 202b is provided on the outer wall of the transmission gear 202. There are two transmission grooves 203b-1, and each transmission groove 203b-1 is provided with a transmission column to cooperate with it.

[0039] In summary, when the height of the inner frame 201 needs to be fixed, the transmission gear 202 can be controlled to rotate, and the rotation of the transmission gear 202 will cause the transmission plate 203b to rotate accordingly. The rotation of the transmission plate 203b will cause the clamping plate 203c, which can only move horizontally, to be displaced through the cooperation between the transmission slot 203b-1 and the transmission column, so that it can be inserted into the connecting through hole, thereby completing the fixing of the inner frame 201.

[0040] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention, is different from the previous embodiment in that a rotation method of a transmission gear 202 is provided.

[0041] Specifically, the wire fixing assembly 300 further includes a control member 302, which includes a column 302a screwed to the outer wall of the fixing frame 301, and the column 302a is movably connected to the fixing tube 201a. The column 302a will serve as a carrier for carrying other components of the control member 302.

[0042] The outer wall of the column 302a is provided with a first transmission tooth groove 302a-1 meshing with the transmission gear 202, and the column 302a is also provided with a ratchet 305. The column 302a is provided with a receiving groove 302a-2, and a movable frame 303 is movably provided in the receiving groove 302a-2. Figure 8 The column 302a is divided into three areas, one part of which is provided with a first transmission tooth groove 302a-1, the second part is a ratchet 305, and the third part is used to assemble the movable frame 303.

[0043] A second transmission tooth groove is disposed outside the movable frame 303, and a control gap 302a-3 is provided between one end of the movable frame 303 and the receiving groove 302a-2, and a pawl 204 is disposed outside the inner frame 201. The pawl 204 will cooperate with the ratchet 305, so that the movement of the column 302a is unidirectional. If resetting is required, the pawl 204 needs to be controlled to be separated from the contact of the ratchet 305. The control gap 302a-3 allows the movable frame 303 to only move in one direction and reset.

[0044] The outer wall of the movable frame 303 is hinged with a rotating rod 303a on both sides, and the rotating rod 303a is hinged with the accommodating groove 302a-2 at one end away from the movable frame 303, and the outer wall of the movable frame 303 is provided with a second elastic member 304. The second elastic member 304 is in a "convex" shape, and when the movable frame 303 is displaced, thereby compressing the control gap 302a-3, the second elastic member 304 can provide a certain reset effect.

[0045] A telescopic rod 202c is provided in the inner frame 201, a first elastic member 201a-1 is provided in the fixed cylinder 201a, an observation window 101d is provided through the outer wall of the outer frame 101, and a connecting slide 101c is provided in the outer frame 101. The observation window 101d is used to observe the rotation state of the transmission gear 202. If the warning end 202b is displayed in the observation window 101d, it means that the column 302a is plugged in place. The connecting slide 101c is used to ensure that the inner frame 201 has a certain stability when adjusting the height.

[0046] It should be noted that, under normal circumstances, the telescopic rod 202c is inserted into the tooth groove of the transmission gear 202, and the extension and retraction of the telescopic rod 202c will have a certain reset effect, which gives the transmission gear 202 a certain force to overcome when rotating.

[0047] In summary, before determining the specific height of the wire clamp 301a, a height test can be performed first. The specific test process is to control the inner frame 201 to rotate, insert the column 302a with the transmission tooth groove 302a-1 into the fixed cylinder 201a, at this time, the transmission gear 202 rotates. Combining the above embodiment, it can be known that the rotation of the transmission gear 202 will fix the inner frame 201. At this time, the staff can judge whether the current height meets the installation requirements according to the cable installation requirements, and then pull out the column 302a.

[0048] If the condition is not satisfied, multiple adjustments can be made. If the condition is satisfied, the cylinder 302a is rotated so that the ratchet 305 is located below the pawl 204, and the cylinder 302a is inserted again. Due to the design of the pawl 204, after the cylinder 302a is inserted, the transmission gear 202 will rotate through the second transmission tooth groove on the movable frame 303, thereby achieving the fixation of the wire fixing assembly 300 in the adjustment assembly 200 and the fixation of the adjustment assembly 200 in the bearing assembly 100.

[0049] The present invention also provides a correction method. If the tested wire clamp 301a still does not meet the installation requirements and needs to be adjusted again, the pawl 204 can be pressed to disengage it from the ratchet 305, and then the column 302a can be pulled out. In this process, the transmission gear 202 will no longer rotate. The transmission gear 202 will push the movable frame 303 to move into the receiving groove 302a-2 under the support of the rotating rod 303a, and disengage from the meshing with the transmission gear 202. Since there is a cable in the wire clamp 301a at this time, if the two are adjusted at the same time, the staff still needs to overcome the tension of the cable, and first remove the wire fixing component 300, and then control the transmission gear 202 to rotate until it is reset, so as to adjust the height of the inner frame 201, which can effectively reduce the labor intensity of the staff.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
