Description

Technical Field

[0001] This utility model relates to the field of cable support technology, and in particular to a movable temporary cable overhead device. Background Technology

[0002] Temporary power supply is required at construction sites in various industries such as water conservancy, construction, and municipal engineering. Because temporary power supply within the site is subject to significant fluctuations and short usage periods, it is generally not buried underground or installed on poles, but rather using overhead cable supports. Currently, the common construction method on site is to purchase prefabricated cable supports and temporarily lay cables overhead.

[0003] Currently available commercially available temporary cable supports are made of plastic and have an overall triangular pyramidal frame structure with a U-shaped recessed bracket at the top that opens upwards. When installing overhead cables, only one cable can be installed on a single support at a time. Furthermore, the U-shaped bracket at the top of the support is easily damaged, and the support is lightweight, making it prone to tipping over and causing the cable to fall to the ground, posing a safety hazard. After several tipping incidents, the support legs are prone to bending and breaking, increasing the cost of use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that temporary cable supports on the market are prone to tipping over and being damaged, and to propose a movable temporary cable overhead device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable temporary overhead cable device includes a frame, which includes uprights, legs, and a first crossbar. Two legs are spaced apart, and uprights are mounted on the two legs. The first crossbar is positioned between the two uprights and is located on the upper part of the uprights. Insulating sleeves are fitted onto the uprights and the first crossbar.

[0007] Furthermore, the two uprights are inclined so that the distance between their tops is less than the distance between their bottoms.

[0008] Furthermore, a second crossbar is provided below the first crossbar, and the two ends of the second crossbar are fixedly connected to the upright.

[0009] Furthermore, the insulating sleeve includes a crossbar sleeve on the first crossbar that is fitted onto the crossbar sleeve and an upright sleeve on the portion of the upright located above the first crossbar.

[0010] Furthermore, the upright sleeve and the crossbar sleeve are integrally formed structures.

[0011] Furthermore, the bottom of the crossbar sleeve is provided with a first opening, which extends through the crossbar sleeve axially.

[0012] Furthermore, a second opening is provided at the top of the crossbar sleeve along the cable laying direction. The depth of the second opening is the same as the radius of the crossbar sleeve, and multiple second openings are spaced apart along the axial direction of the crossbar sleeve.

[0013] Furthermore, the top of the pole sleeve is located above the top of the pole.

[0014] Furthermore, the insulating sleeve is a corrugated pipe or a snakeskin tube.

[0015] Furthermore, the frame is constructed using welded steel bars.

[0016] Compared with the prior art, the present invention provides a movable temporary overhead cable device, which has the following advantages:

[0017] This utility model discloses a portable temporary cable overhead device. Before use, materials can be sourced locally at the construction site. The frame is welded from scrap steel bars on the construction site, and pipes made of insulating material available on the construction site are fitted onto the first horizontal bar and the vertical bar. The length of the horizontal bar and the welding position with the vertical bar can be selected according to the number of cables required.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 This utility model discloses a movable temporary overhead cable device, which includes a frame 1. The frame 1 includes uprights 3, legs 4, and a first crossbar 5. The uprights 3, legs 4, and the first crossbar 5 can all be made of scrap steel bars.

[0029] Two support legs 4 are spaced apart. Both support legs 4 are rod-shaped structures, and the axial direction of the two support legs 4 is the same as the laying direction of the cable.

[0030] A vertical pole 3 is welded to the middle of the top of the two support legs 4. A first horizontal bar 5 is set between the two vertical poles 3. The first horizontal bar 5 is located on the upper part of the vertical pole 3. The top of the first horizontal bar 5 and the top of the vertical pole 3 form a U-shaped bracket groove with an open top. The bracket groove is used to place the overhead cable.

[0031] Insulating sleeves 2 are fitted onto the upright 3 and the first horizontal bar 5 to ensure the insulation of the device and improve its safety.

[0032] The two uprights 3 are set at an angle so that the distance between the top of the two uprights 3 is smaller than the distance between the bottom, so that the bracket groove forms a U-shaped groove with a small opening at the top and a large distance between the bottom sides.

[0033] When the cable is overhead, the cable itself is wavy in shape. The highest point of the cable is at the first horizontal bar 5, and the lowest point of the cable is in the middle of the two devices. The lowest point does not touch the ground. At the same time, the cable sheath is hard and smooth, so it is easy to slide along the axial direction of the first horizontal bar 5 when it is overhead. The inclined arrangement of the two uprights 3 allows the two support legs 4 to be located on the outside of the two ends of the first horizontal bar 5, preventing the device from tilting to the side.

[0034] A second crossbar 6 is welded below the first crossbar 5, and both ends of the second crossbar 6 are fixedly connected to the upright 3.

[0035] Without the second horizontal bar 6, the first horizontal bar 5, together with the two uprights 3 and the support legs 4, forms a U-shape. After the second horizontal bar 6 is installed, the whole structure forms a square frame structure, which is more stable.

[0036] The insulating sleeve 2 includes a crossbar sleeve 8 on the first crossbar 5 that is fitted onto the crossbar sleeve 8 and a vertical pole sleeve 7 on the portion of the vertical pole 3 located above the first crossbar 5.

[0037] During installation, only the upper part of the upright 3 and the first horizontal bar 5 come into contact with the cable. Therefore, the insulating sleeve 2 is only installed on the upright 3 and the first horizontal bar 5, which can reduce the manufacturing cost while ensuring the insulation effect.

[0038] The upright sleeve 7 and the crossbar sleeve 8 are integrally formed structures.

[0039] The upright sleeve 7 and the crossbar sleeve 8 can also be made from scrap pipes from the construction site. Simply bend a pipe and fit it onto the surface of the upright 3 and the first crossbar 5.

[0040] The bottom of the crossbar sleeve 8 is cut with a first opening 9, which extends through the crossbar sleeve 8 axially.

[0041] Specifically, take a pipe, take a section in the middle that is shorter than the axial length of the first crossbar 5 as the crossbar sleeve 8, and the two ends as the vertical sleeves 7. Cut at the bottom of both ends of the crossbar sleeve 8 without cutting through, so that the crossbar sleeve 8 and the vertical sleeve 7 are connected. Then bend the vertical sleeve 7 in the opposite direction, and then process the first opening 9 at the bottom of the crossbar sleeve 8.

[0042] In use, first put the two pole sleeves 7 on the pole 3, then slide them down so that the first horizontal bar 5 passes through the first opening 9, and put the horizontal bar sleeve 8 on the first horizontal bar 5.

[0043] After installation, the cable is laid in the bracket groove between the upright sleeve 7 and the horizontal sleeve 8, making it difficult for the upright sleeve 7 and the horizontal sleeve 8 to fall off the frame 1 and be lost.

[0044] The top of the crossbar sleeve 8 is provided with a second opening 10 along the cable laying direction. The second opening 10 has the same depth as the radius of the crossbar sleeve 8, and multiple second openings 10 are spaced apart along the axial direction of the crossbar sleeve 8.

[0045] Specifically, after selecting a corrugated pipe, the pipe wall is made of plastic, and a helical spring is embedded inside the pipe wall. The second opening 10 is opened in the gap of the helical spring. During manufacturing, an angle grinder can be used to remove the plastic at the second opening 10. When the cable is laid on the crossbar sleeve 8, the axial friction between the cable and the crossbar sleeve 8 can be increased, reducing the lateral sliding of the cable in the bracket groove.

[0046] To ensure insulation, an inner sleeve can be installed inside the crossbar sleeve 8. The inner sleeve is another crossbar sleeve 8 without a second opening 10. The two crossbar sleeves 8 are stacked to ensure insulation.

[0047] The top of pole sleeve 7 is located above the top of pole 3.

[0048] This allows the pole sleeve 7 to completely cover the upper part of the pole 3, preventing the top of the pole 3 from being exposed. This is to prevent scratches to workers and cables.

[0049] Insulating sleeve 2 is a corrugated pipe or a snake-skin pipe.

[0050] Insulating sleeve 2 is mainly made of flexible tubing, such as corrugated pipe or snakeskin pipe. The main advantage is that the materials are readily available and the manufacturing process is simple. Corrugated pipe and snakeskin pipe have stable performance, are wear-resistant, high-temperature resistant and corrosion-resistant, making them suitable for outdoor construction environments such as construction sites.

[0051] The frame 1 is made of welded steel bars.

[0052] Except for the insulating sleeve 2, all other structures in this device can be made of welded steel bars. The most common round steel bars and threaded steel bars on the construction site are 6 / 6.5 / 8mm. Choose the appropriate steel bar specifications according to the number and weight of the cables to be laid.

[0053] During welding, ensure that the minimum size of the reinforcing bars meets the usage requirements. The specifications of the reinforcing bars can be varied, and reinforcing bars of different lengths and thicknesses can be welded together to form the structure of frame 1.

[0054] The two support legs 4 are parallel to each other.

[0055] The two steel bars used to make the support legs 4 are parallel to each other, so that the support legs 4 have a good supporting effect in both the axial and radial (lateral) directions along the cable when supporting the device.

[0056] Working principle: During the construction process, steel bars from the construction site are welded into frame 1. An angle grinder is used to cut the inner tube sleeve and the insulating sleeve 2. First, the inner tube sleeve is put on the first horizontal bar 5. Then, corrugated pipe is cut into insulating sleeve 2 and put on frame 1.

[0057] When in use, place the support legs 4 along the cable laying direction, select the number and spacing according to the site conditions, adjust the position of the device, and then suspend the temporarily laid cable in the bracket groove formed by the upright 3 and the first horizontal bar 5.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
