[0001] This utility model belongs to the technical field of cable suspension tools, specifically relating to a handheld support frame for cable suspension in mine roadways. Background Technology

[0002] In underground coal mine roadways, especially in equipment installation areas such as substations, it is often necessary to lay large-section, heavy-weight armored cables. For example, a 240mm² armored cable can weigh up to 20 kilograms per meter and needs to be suspended at a height of more than 2 meters above the ground.

[0003] Currently, the support frame used for cable hanging includes a support rod and a semi-circular cable tray fixed to one end of the support rod. During use, workers place the cable in the cable tray, hold the support rod, lift it to the cable hook on the side wall of the tunnel, and place the cable inside. However, underground tunnel space is limited, and the planned cable laying path is often surrounded by various conduits such as ventilation ducts, water pipes, signal lines, and lighting lines. These conduits occupy the working space, and the cable tray is prone to accidentally contacting other conduits, seriously affecting the cable hanging process, resulting in inaccurate cable positioning, numerous adjustments, and extremely low installation efficiency.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. In this invention, "direction" refers to the orientation of the present invention. Figure 1 Description of the state's progression.

[0013] like Figure 1 and Figure 2 As shown, a handheld support frame for cable hanging in mine roadways includes: a support outer sleeve 1, a support rod 2, a rod pull ring 3, a left cable support groove 4, a right cable support groove 5, and a rod telescopic assembly 6; A pull rod ring 3 is fixedly installed at one end of the support rod 2; like Figure 3 As shown, both the left cable tray 4 and the right cable tray 5 are semi-circular opening structures, and the openings are symmetrically arranged at the other end of the support rod 2. The lower ends of both the left cable tray 4 and the right cable tray 5 are rotatably connected to the support rod 2. The support rod 2 is installed inside the support outer tube 1, and the rod telescopic assembly 6 is arranged around the outer surface of the support rod 2 and the inner surface of the support outer tube 1. When the pull rod ring 3 is pulled, the telescopic assembly 6 extends or is compressed, causing the support rod 2 to move downward within the support outer sleeve 1. This moves the left cable tray 4 and the right cable tray 5 downward. When the outer surfaces of the left cable tray 4 and the right cable tray 5 abut against the upper end of the support outer sleeve 1, the upper ends of the left cable tray 4 and the right cable tray 5 close, clamping the cable within them and placing it in the cable hook on the sidewall of the tunnel. When the pull rod ring 3 is released, the telescopic assembly 6 resets, causing the support rod 2 to move upward within the support outer sleeve 1. This moves the left cable tray 4 and the right cable tray 5 upward, causing their outer surfaces to leave the upper end of the support outer sleeve 1, gradually opening the opening.

[0014] In this invention, the cable trays are automatically opened and closed by means of the support sleeve 1, the support rod 2, and the left and right cable trays 4 and 5, respectively, with the help of the rod telescopic assembly 6. This eliminates the need for manual lifting of heavy cables, significantly reducing workload. The symmetrical semi-circular structure of the left and right cable trays 4 and 5 can precisely clamp the cable, allowing for flexible adjustment of the cable position in confined spaces. This reduces interference from other pipelines hanging on the sidewalls of the tunnel during the cable hanging process, improving installation efficiency and operational safety.

[0015] like Figure 4 As shown, the telescopic rod assembly 6 includes: an outer tube fixing ring 7, a telescopic spring 8, and a rod fixing ring 9 disposed between the support outer tube 1 and the support rod 2; The outer tube fixing ring 7 is fixedly connected to the supporting outer tube 1; The tie rod fixing ring 9 is fixedly connected to the support tie rod 2; The telescopic spring 8 is fixedly connected between the pull rod fixing ring 9 and the outer tube fixing ring 7. The end of the telescopic spring 8 that is fixedly connected to the outer tube fixing ring 7 is the fixed end, and the end of the telescopic spring 8 that is fixedly connected to the pull rod fixing ring 9 is the movable end. In one embodiment, the outer tube fixing ring 7 is located above the pull rod fixing ring 9, the upper end of the telescopic spring 8 is fixedly connected to the lower wall of the outer tube fixing ring 7, and the lower end of the telescopic spring 8 is fixedly connected to the upper wall of the pull rod fixing ring 9.

[0016] Among them, the tie rod fixing ring 9 is used to stretch the telescopic spring 8 when the tie rod ring 3 is pulled, so that the support tie rod 2 moves downward inside the support outer sleeve 1; The tie rod retaining ring 9 is also used to be pulled by the telescopic spring 8 when the tie rod ring 3 is released, so that it is reset, thereby allowing the support tie rod 2 to move upward within the support outer sleeve 1.

[0017] In another embodiment, the pull rod fixing ring 9 is located above the outer tube fixing ring 7, the upper end of the telescopic spring 8 is fixedly connected to the lower wall of the pull rod fixing ring 9, and the lower end of the telescopic spring 8 is fixedly connected to the upper wall of the outer tube fixing ring 7.

[0018] Among them, the tie rod fixing ring 9 is used to compress the telescopic spring 8 when the tie rod ring 3 is pulled, so that the support tie rod 2 moves downward inside the support outer sleeve 1; The tie rod retaining ring 9 is also used to be released by the telescopic spring 8 when the tie rod ring 3 is released, so that the tie rod 2 can move upward within the support outer sleeve 1.

[0019] In this utility model, the pull rod telescopic assembly 6, composed of the outer sleeve fixing ring 7, the telescopic spring 8 and the pull rod fixing ring 9, has a simple structure and reliable transmission, and can realize the reciprocating movement of the support pull rod 2 without the need for an additional power source.

[0020] like Figure 5 As shown, it also includes two pull rod limiting blocks 10. The two pull rod limiting blocks 10 are arranged around the outer surface of the support pull rod 2 and the inner surface of the support outer sleeve 1. They are both fixedly connected to the support outer sleeve 1 and movably connected to the support pull rod 2. The two pull rod limiting blocks 10 are located at one end near the pull rod ring 3 and the other end near the left cable tray 4 and the right cable tray 5, respectively, and play a role in limiting and guiding the support pull rod 2.

[0021] In this utility model, two tie rod limiting blocks 10 limit and guide the two ends of the support tie rod 2 respectively, effectively preventing the support tie rod 2 from shifting, jamming or coming off during the extension and retraction process. At the same time, it reduces the frictional wear between the support tie rod 2 and the inner wall of the support outer sleeve 1.

[0022] like Figure 6 As shown, it also includes a support handle 11, which is located at one end of the support outer sleeve 1 near the pull rod ring 3. The support handle 11 is provided with a ring limiting hook 12, which is used to lock the position of the pull rod ring 3 when the pull rod ring 3 is pulled, so as to keep the left cable tray 4 and the right cable tray 5 in a closed state to stably clamp the cable.

[0023] In this invention, the support handle 11 facilitates prolonged gripping and force application by the operator. The pull ring limiting hook 12 locks the position of the pull rod pull ring 3, keeping the left cable tray 4 and right cable tray 5 continuously closed, eliminating the need for continuous manual pulling of the pull rod pull ring 3. This avoids the risk of cable detachment due to hand slippage during high-altitude operations, improving the efficiency and safety of cable suspension operations.

[0024] The working principle of this utility model is as follows: The operator holds the support handle 11 and pulls the pull rod ring 3. The pull rod telescopic assembly 6 extends or is compressed when the pull rod ring 3 is pulled. The pull rod fixing ring 9 stretches or compresses the spring 8 when the pull rod ring 3 is pulled, causing the support pull rod 2 to move downwards within the support outer sleeve 1. This causes the left cable tray 4 and right cable tray 5 to move downwards. When the outer surfaces of the left cable tray 4 and right cable tray 5 abut against the upper end of the support outer sleeve 1, the upper ends of the left cable tray 4 and right cable tray 5 close, clamping the cable within them. At this time, the pull rod ring... 3. The cable is hung in the pull ring limiting hook 12, and the left cable tray 4 and the right cable tray 5 remain closed. The worker lifts the cable and places it in the cable hook on the side wall of the tunnel. After the cable is hung to the predetermined position, the pull ring 3 of the pull rod is removed from the pull ring limiting hook 12. The pull rod fixing ring 9 is pulled or popped open by the telescopic spring 8, so that the support pull rod 2 moves upward in the support outer sleeve 1. The pull rod telescopic component 6 is reset. The support pull rod 2 moves upward in the support outer sleeve 1, which drives the left cable tray 4 and the right cable tray 5 to move upward. The outer surfaces of the left cable tray 4 and the right cable tray 5 leave the upper end of the support outer sleeve 1, and the opening gradually opens.

[0025] In summary, this utility model, through the cooperation of the supporting outer sleeve 1, the supporting tie rod 2, and the left and right cable trays 4 and 5, and with the aid of the tie rod telescopic assembly 6, achieves automatic opening and closing of the trays, eliminating the need for manual lifting of heavy cables and significantly reducing labor intensity. The symmetrical semi-circular structure of the left and right cable trays 4 and 5 can accurately clamp the cable, allowing for flexible adjustment of the cable position in confined spaces, reducing positioning deviations and adjustment frequency, minimizing interference from other pipelines hanging on the tunnel sidewalls during the cable hanging process, and improving the installation efficiency and operational safety of the cable hanging system.
