Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cable clamps, and particularly relates to a combined cable clamp of low alloy steel and cast steel. Background Art
[0002] The cable clamp is usually annular or semi-annular and is usually made of low alloy steel or cast steel. It consists of two or more parts to enable the cable clamp to hold factors such as the diameter, shape, and tensile force of the steel cable. The inner wall of the cable clamp is in close contact with the steel cable to ensure that the steel cable can be firmly clamped.
[0003] Currently, two sets of arc-shaped semi-annular cable clamps are sleeved on both sides of the steel cable, and the two sets of semi-annular cable clamps are screwed and fixed by bolts passing through the two sets of semi-annular cable clamps, so as to tightly clamp the steel cable by the two sets of semi-annular cable clamps. However, in actual use, since the current length of the cable clamp is fixed and the contact surface with the cable is limited, the cable can be used normally when bearing a small tensile force. When bearing a large tensile force, the cable clamp with a small area is difficult to provide enough friction, which easily causes excessive local stress on the cable clamp, increases the risk of damage to the cable clamp, and thus makes it difficult to stably clamp the steel cable, reducing the structural safety. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a combined cable clamp of low alloy steel and cast steel to solve the problems raised in the above background art.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] The present utility model provides a Figures 1-4 low-alloy steel and cast steel combined cable clamp as shown, including:
[0024] The first jacket 1, the bottom of the first jacket 1 is screwed with the second jacket 2, and both the first jacket 1 and the second jacket 2 are semicircularly arranged. The two sides of the first jacket 1 are connected with the first fixing ear 3, the two sides of the second jacket 2 are connected with the second fixing ear 4, and the first fixing ear 3 and the second fixing ear 4 are screwed and fixed. One end of each of the first fixing ear 3 and the second fixing ear 4 is screwed with a connecting ear 5, and the connecting ear 5 is screwed with an adjacent group of the first jacket 1 and the second jacket 2 to increase the length of the first jacket 1 and the second jacket 2.
[0025] The other ends of the first fixing ear 3 and the second fixing ear 4 are both provided with a first threaded hole 6, the surface of the connecting ear 5 is provided with a second threaded hole 7, and the connecting ear 5 is screwed and fixed with the first threaded hole 6 through a bolt passing through the second threaded hole 7.
[0026] A number of insertion blocks 8 are connected to the bottom of the first fixing ear 3, and a fastening bolt 9 is provided between the two groups of insertion blocks 8. A number of insertion slots 10 are provided on the top surface of the second fixing ear 4, and a fastening threaded hole 11 is provided between the two groups of insertion slots 10. After the insertion block 8 is inserted into the insertion slot 10, the first fixing ear 3 and the second fixing ear 4 are fixed by screwing the fastening bolt 9 into the fastening threaded hole 11. After the insertion block 8 is inserted into the insertion slot 10, the first clamping sleeve 1 and the second clamping sleeve 2 can be connected at the correct position, and it can also effectively prevent the first clamping sleeve 1 and the second clamping sleeve 2 from being misaligned at the connection part, greatly improving the installation efficiency.
[0027] A cable clip ear plate 12 is connected to the top of the first clamping sleeve 1. The cable clip ear plate 12 can provide a connection point for the first clamping sleeve 1 and can be connected to external rigging, brackets or other structures.
[0028] Rubber pads 13 for increasing friction are provided inside both the first clamping sleeve 1 and the second clamping sleeve 2. The rubber pads 13 can increase the friction between the first clamping sleeve 1 and the second clamping sleeve 2 and the steel cable, and can also prevent the steel cable from directly contacting the first clamping sleeve 1 and the second clamping sleeve 2 hard, thereby reducing the wear of the steel cable.
[0029] The first clamping sleeve 1 and the second clamping sleeve 2 are made of rolled low-alloy steel, and the first fixing ear 3 and the second fixing ear 4 are of cast steel structure. After the low-alloy steel is processed by the rolling process, it has high strength. Cast steel has high strength and stiffness and can withstand large external forces, making the first clamping sleeve 1 and the second clamping sleeve 2 not easily deformed or damaged during use, ensuring the firm clamping of the steel cable.
[0030] For this low-alloy steel and cast steel combined cable clip, the first clamping sleeve 1 and the second clamping sleeve 2 are respectively sleeved on both sides of the steel cable, and the insertion block 8 on the first fixing ear 3 on the surface of the first clamping sleeve 1 is inserted into the insertion slot 10 on the second fixing ear 4 on the surface of the second clamping sleeve 2 to ensure that the first clamping sleeve 1 and the second clamping sleeve 2 can be connected at the correct position. It can also effectively prevent the first clamping sleeve 1 and the second clamping sleeve 2 from being misaligned at the connection part, greatly improving the installation efficiency. After correct positioning, the fastening bolt 9 can be screwed to be screwed and fixed with the fastening threaded hole 11, so as to screw and fix the first clamping sleeve 1 and the second clamping sleeve 2, so that the first clamping sleeve 1 and the second clamping sleeve 2 firmly clamp the steel cable. The rubber pads 13 inside the first clamping sleeve 1 and the second clamping sleeve 2 can increase the friction between the first clamping sleeve 1 and the second clamping sleeve 2 and the steel cable, so that the first clamping sleeve 1 and the second clamping sleeve 2 can clamp the steel cable more firmly and prevent the fastened first clamping sleeve 1 and the second clamping sleeve 2 from sliding on the surface of the steel cable.
[0031] When it is necessary to extend the lengths of the first jacket 1 and the second jacket 2, the first jacket 1 and the second jacket 2 that need to be extended can repeat the above operations to insert the insertion block 8 into the slot 10 for correct positioning, and pull the first jacket 1 and the second jacket 2 on the steel cable to approach a neighboring set of the first jacket 1 and the second jacket 2, and align the first threaded holes 6 on the first fixing ears 3 and the second fixing ears 4 on the surfaces of the pulled first jacket 1 and the second jacket 2 with the second threaded holes 7 on the connection ears 5 on the surfaces of the neighboring set of the first jacket 1 and the second jacket 2, and fix them by screwing bolts passing through the second threaded holes 7 with the first threaded holes 6, thereby completing the connection of the two sets of the first jacket 1 and the second jacket 2, increasing the lengths of the first jacket 1 and the second jacket 2 themselves, and thus improving the tensile force borne by the first jacket 1 and the second jacket 2 by extending the lengths of the first jacket 1 and the second jacket 2.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
