Description

Technical Field

[0001] The present invention relates to the technical field of cable hook installation, in particular to a cable hook installation device and an installation method. Background Art

[0002] When laying cables or for later maintenance of cables, cable hooks need to be installed. The current cable hook installation method is: the installer places the ladder at the cable location, the installer stands on the ladder, and installs the cable hook on the cable and the steel wire rope. After installation here, the ladder is moved to the next cable installation location, and the above steps are repeated until the cable hooks required on the line are installed. The current installation method has many problems: the installer needs to work at a height, which is unsafe. The installation ladder needs to be hit on the steel wire rope, and the ladder is easy to shake, which increases the risk of installation. During installation, it is necessary to climb up and lie down, and move the ladder back and forth, which is labor-intensive and inefficient. Another way to install hooks in the prior art is for the installer to ride on a pulley and sit on the steel wire to slide. In many cases, the pole is old and prone to falling and electric shock.

The blocking member 3 presses against three points on the upper part of the slider. After the slider moves, the blocking member enters the grooves on both sides of the slider, thereby pressing against the slider below.

[0029] The difference between Example 2 and Example 1 is that a steel cable guide 2 is provided on one side of the upper portion of the shell 1 to facilitate the steel cable to enter the bottom between the shell and the steel cable guide.

[0030] The difference between Example 3 and Example 2 is that the housing 1 includes a left housing 1-1 and a right housing 1-2 that engages with the left housing 1-1 to facilitate assembly. Side holes 23 are provided on the left and right housings 1-1 and 1-2 for extending the hook fixing rod 5. The hook fixing rod is L-shaped.

[0031] The difference between Example 4 and Example 3 is that the slider reset member 15 is provided with a reset button 21, and the left housing is provided with a sliding hole 14 that matches the reset button 21, so as to facilitate pressing down the slider reset member to reset it.

[0032] The difference between Example 5 and Example 4 is that the two hook fixing mechanisms are respectively located on both sides of the connecting seat, so as to facilitate pulling the cable hook apart.

[0033] The slider reset member 15 is provided with a spring positioning block 19 that matches the compression spring, and the slider 6 is provided with a spring positioning groove 26 to play a positioning role, and the slider has good lateral movement stability.

[0034] The difference between Example 6 and Example 5 is that the sliders 6 are connected by a clamp 28 and a clamp groove 27 provided on the slider, and the slider block 16 is provided with a clamp groove 27 matching the clamp 28, so that the sliding connection has good lateral stability.

[0035] A clamping piece matching the lowermost slider is provided under the slider reset piece, and the first tightening spring is located under the clamping piece under the slider reset piece, so the operation stability is good.

[0036] The difference between Example 7 and Example 6 is that an inclined guide 6-1 is provided on the slider to facilitate sliding and squeezing the slider to move it sideways.

[0039] The difference between Example 10 and Example 9 is that the drive mechanism is a manual or electric drive mechanism. The manual drive mechanism comprises a sleeve 13 mounted on a pull rod 12. The sleeve 13 is connected to a pull-down linkage 18 via a cable 11. A spring sleeve (similar in structure to an electric vehicle brake cable) is provided around the pull rope to prevent friction between the pull rope and the pull rod and housing, providing a guide and easing pulling.

[0040] The difference between Example 11 and Example 10 is that the electric drive mechanism is an electric telescopic rod arranged on the pull rod 11, the telescopic end of the electric telescopic rod is connected to the pull-down linkage member through the wire 11, the pull rod 12 is provided with a battery connected to the electric telescopic rod, the electric telescopic rod is installed in the pull rod, and the switch is set on the pull rod. When the switch is pressed, the electric pull rod works.

[0041] Example 12: A cable hook installation method, comprising the following steps: sequentially hanging the hook 4 on the hook fixing rod of the slider, connecting the two hook fixing rods on both sides of the seat to deform the hook so that it is easy to be inserted into the steel cable; the generated torque is tightly fixed on the hook fixing rod of the slider;

[0042] Place the cable to be hung into the gap between the two shells (direction A in the figure) and insert the cable into the hook;

[0043] Lift the device so that the cable enters the gap between the housing and the guide (direction B in the figure), and use the lifting force to slide the cable into the bottom of the housing and the guide;

[0044] Pull the sliding sleeve of the pull rod downward, the sliding sleeve drives the two cables to move downward, the cables drive the two pull-down linkages to move downward, the action of the bevel guide of the pull-down linkage and the slider causes the sliders on both sides to move backward, causing the hook to be unhooked. The hook shrinks instantly due to its own deformation force and hangs on the cable;

[0045] Move the device downward so that the steel cable leaves the gap between the housing and the guide member, and the positioning member does not press against the uppermost slider. Under the action of the first tensioning spring, the slider moves upward to facilitate the next slider to be in place, and then the steel cable is placed in the housing and the guide member for reciprocating operation.

[0046] After all the sliders have finished rising, press the slider reset piece to move it downward to restore all the sliders to their original positions.

[0047] When inspecting cables, the device of the present invention finds that the hook on the cable has fallen off, or when the cable is being installed, the hook is hung on the hook fixing rod of the slider, and the two hook fixing rods on both sides of the connecting seat cause the hook to be deformed, making it easy to fit into the steel cable; the generated torsion is tightly fixed on the hook fixing rod of the slider; the cable to be hung is placed in the gap between the two shells, and the cable enters the hook; the device is lifted to allow the steel cable to enter the gap between the shell and the guide member, and the lifting force is used to slide the steel cable into the bottom of the shell and the guide member; the sliding sleeve of the pull rod is pulled downward, and the sliding sleeve drives the two wires to move downward, and the wires drive the two pull-down links The movable part moves downward, and the action of the beveled guide part and the slider of the downward-pulling linkage part causes the two sliders on both sides to move backward relative to each other, causing the hook to be unhooked. The hook shrinks instantaneously due to its own deformation force and hangs on the steel cable; the device is moved downward, so that the steel cable leaves the gap between the shell and the guide part, and the positioning part does not press on the uppermost slider. Under the action of the first tensioning spring, the slider moves upward, and the slider reset part also moves up by the height of a slider, so that the next slider is in place, and then the steel cable is placed in the shell and the guide part for reciprocating operation; after all the sliders have risen, the slider reset part is pressed downward to restore all the sliders to their original positions. When installing the cable hook, the device of the present invention does not require a ladder, does not require climbing and moving the ladder, and has high efficiency in installing the hook, can be operated continuously, and is safe to operate.
