Description

Technical Field

[0001] This utility model belongs to the field of low-voltage wiring technology, specifically a cable tray laying auxiliary device. Background Technology

[0002] In cabling, strong and weak currents are generally classified as follows: cables used to transmit current are called strong current cables, while cables used to transmit information are called weak current cables. For example, network cables are a type of weak current cable. When cabling network cables, it is generally necessary to bundle them tightly and then lay them in the pre-laid cable trays.

[0003] During the cabling process, since the cables are located on the ground while the cable trays are located high in the air, if the cables are forcibly pulled into the cable trays, the friction between the end of the cable trays and the cable supports will damage the cable sheath and the cable. At the same time, the cables are classified according to their function groups. Whether for aesthetics or for ease of future maintenance, a group of cables usually needs to be bundled together, and the cables must be kept tight and not loose.

[0004] The existing method involves using a pulley to clamp the cables onto the cable tray, then manually squeezing multiple sets of cables together, bundling them with cable ties, and finally laying the cables into the cable tray along the pulley. This method is labor-intensive and has low efficiency in installing cable ties. Therefore, a new device needs to be designed to improve the efficiency of the auxiliary operation. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for cable tray laying in order to solve the above-mentioned problems.

[0006] The technical solution adopted by this utility model is as follows: a cable tray laying auxiliary device, wherein there is a first telescopic support rod and a second telescopic support rod outside the cable tray, and a guide mechanism that can guide the cable is provided above the first telescopic support rod;

[0007] The guiding mechanism includes: a support plate, a telescopic adjusting rod, an extension plate, a locking plate, a locking bolt, a guide groove A, and a guide roller. The top of the first telescopic support rod is rotatably connected to the support plate, and the telescopic adjusting rod is fixedly installed on the surface of the support plate. The telescopic end of the telescopic adjusting rod is rotatably connected to the guide groove A through a rotating shaft, and the guide roller is rotatably connected inside the guide groove A.

[0008] The support plate is rotatably connected to an extension plate at its end, and an interlocking plate is integrally provided at the bottom of the extension plate, with a locking bolt embedded at the bottom of the interlocking plate.

[0009] The top of the second telescopic support rod is rotatably connected to a cable tray. A tensioning mechanism that can pull the cable in the reverse direction is embedded in the middle of the cable tray, and a cable bundling structure that facilitates the bundling of the cable bundle is provided at the end of the cable tray.

[0010] The tensioning mechanism includes a limiting frame, a guide groove B, a bushing, an adjusting screw, a reverse roller, and a shaft head. The limiting frame is embedded in the middle of the hub tube. The upper part of the limiting frame is symmetrically provided with guide grooves B. The limiting frame is provided with bushings inside. There are four bushings, which are arranged in groups of two. One group is slidably disposed in the guide groove B, and the other group is installed in the limiting frame. Each group of bushings is rotatably connected to a shaft head. The shaft heads are movably connected to each other.

[0011] An adjusting screw is rotatably connected above the bushing located in the guide groove B, and the adjusting screw extends out of the limiting frame and engages with the limiting frame by threads.

[0012] The wire harness structure includes a wire harness cavity and ball bearings. The wire harness cavity is threadedly connected to the end of the wire gathering tube. A ball bearing is inserted and rotated into the inner wall of the opening edge of the wire harness cavity through a groove. The wire harness cavity is conical in shape.

[0013] The reverse roller has a protrusion at its end, which fits into the shaft head and is locked by a fastening bolt. The reverse roller has a groove on its surface, and a rubber layer is tightly attached to the surface of the groove.

[0014] A fastening bolt is embedded in the rotating shaft sleeve at the connection between the telescopic end of the telescopic adjustment rod and the guide groove A.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the locking bolt is rotated to fix the interlocking plate to the cable tray. At the same time, the guide groove A is rotated by the rotating shaft. After adjustment, it can be locked by the fastening bolt so that the guide groove A corresponds with the cable tray. The guide roller can avoid friction between the cable and the cable tray, avoid cable breakage, and provide better protection for the cable.

[0017] 2. In this utility model, when wiring is performed, the motor drives the shaft head to reverse. Since the surface of the reverse roller is provided with a groove and the surface of the groove is tightly fitted with a rubber layer, the rubber layer will generate a slight friction force between the cable and the cable, which will tighten the cable in the reverse direction. When the friction force is too large, the adjustment screw can be rotated to adjust the screw linkage sleeve to move up and down inside the guide groove B, thereby adjusting the spacing. This design can improve the tension of the cable during wiring operations and prevent it from becoming loose.

[0018] 3. In this utility model, when the cable passes through the cable bundling cavity, the parallel cables can be stranded together. At the same time, the ball bearings can reduce the friction of the cable and protect it. The operator can put the rubber band behind the cable bundling cavity in advance. As the cable moves, the operator can pull out the rubber band and tighten the cable with the rubber band every 10-15 cm. In order for the rubber band to slide smoothly, the conical design of the cable bundling cavity can increase the rolling of the rubber band, making it easier to tighten the cable. It is also convenient to operate and more efficient. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In this utility model:

[0028] Reference Figure 1-6A cable tray laying auxiliary device, wherein the cable tray 1 has a first telescopic support rod 2 and a second telescopic support rod 4 outside, and a guide mechanism that can guide the cable is provided above the first telescopic support rod 2;

[0029] The guiding mechanism includes: a support plate 201, a telescopic adjusting rod 202, an extension plate 203, a locking plate 2031, a locking bolt 2032, a guide groove A3, and a guide roller 301. The support plate 201 is rotatably connected to the top of the first telescopic support rod 2. The telescopic adjusting rod 202 is fixedly mounted on the surface of the support plate 201. The telescopic end of the telescopic adjusting rod 202 is rotatably connected to the guide groove A3 via a rotating shaft. The guide roller 301 is rotatably connected inside the guide groove A3, and the guide groove A3 is rotated via the rotating shaft. After adjustment, the guide roller 301 can be locked using the locking bolt to ensure that the guide groove A3 corresponds to the cable tray 1. The guide roller 301 prevents friction between the cable and the cable tray 1, thus preventing cable breakage.

[0030] An extension plate 203 is rotatably connected to the end of the support plate 201. An interlocking plate 2031 is integrally provided at the bottom of the extension plate 203. A locking bolt 2032 is embedded at the bottom of the interlocking plate 2031 to interlock the interlocking plate 2031 with the cable tray 1. At this time, the interlocking plate 2031 and the cable tray 1 are fixed by rotating the locking bolt 2032.

[0031] The top of the second telescopic support rod 4 is rotatably connected to a cable tray 5. A tensioning mechanism that can pull the cable in the reverse direction is embedded in the middle of the cable tray 5, and a cable bundling structure that facilitates the bundling of the cable bundle is provided at the end of the cable tray 5.

[0032] Furthermore, the tensioning mechanism includes a limiting frame 6, a guide groove B601, a bushing 602, an adjusting screw 6021, a reverse roller 603, and a shaft head 6031. The limiting frame 6 is embedded in the middle of the cable conduit 5. The upper part of the limiting frame 6 is symmetrically provided with guide grooves B601. The limiting frame 6 is provided with bushings 602 inside. There are four bushings 602, two in a group. One group is slidably disposed in the guide groove B601, and the other group is installed in the limiting frame 6. The motor drives the shaft head 6031 to reverse. Since the surface of the reverse roller 603 is provided with grooves and the surface of the grooves is tightly attached with a rubber layer, the rubber layer will generate a slight friction force with the cable, thus tensioning the cable in the reverse direction.

[0033] An adjusting screw 6021 is rotatably connected above the bushing 602 located in the guide groove B601. The adjusting screw 6021 extends out of the limiting frame 6 and engages with the limiting frame 6 by threads. When the friction is too great, the adjusting screw 6021 can be rotated, and the adjusting screw 602 moves up and down inside the guide groove B601 in conjunction with the bushing 602, thereby adjusting the spacing. This design can improve the tension of the cable and prevent it from becoming loose during wiring operations.

[0034] Furthermore, each set of bushings 602 is rotatably connected to a shaft head 6031, and a reverse roller 603 is movably connected between the shaft heads 6031. The reverse roller 603 has a protrusion at its end, which fits with the shaft head 6031 and is locked by fastening bolts. The surface of the reverse roller 603 has a groove, and a rubber layer is tightly attached to the surface of the groove. When a large number of cables are required, the reverse roller 603 can be replaced by removing the fastening bolts, using the protrusion at its end that fits with the shaft head 6031, to replace the reverse roller 603 with the one corresponding to the number of cables.

[0035] Furthermore, the cable harness structure includes: a cable harness cavity 7 and ball bearings 701. The cable harness cavity 7 is threadedly connected to the end of the cable conduit 5. The cable harness cavity 7 can be replaced according to usage requirements. The ball bearings 701 are inserted and rotated through grooves on the inner wall of the opening edge of the cable harness cavity 7. The cable harness cavity 7 is conical in shape. When the cable passes through the cable harness cavity 7, the parallel cables can be stranded together. At the same time, the ball bearings 701 can reduce the friction of the cable and protect the cable. The operator can put the rubber band behind the cable harness cavity 7 in advance. As the cable moves, the operator can pull out the rubber band and tighten the cable with the rubber band every 10-15 cm. In order for the rubber band to slide smoothly, the conical design of the cable harness cavity 7 can increase the rolling of the rubber band and facilitate the tightening of the cable.

[0036] Furthermore, a fastening bolt is embedded in the pivot sleeve at the connection between the telescopic end of the telescopic adjustment rod 202 and the guide groove A3, and the guide groove A3 is rotated by the pivot. After adjustment, the fastening bolt can be used to lock the guide groove A3 to correspond with the cable tray 1. The guide roller 301 can prevent friction between the cable and the cable tray 1, thus preventing the cable from breaking.

[0037] Furthermore, locking bolts are embedded in the outer sleeves of the first telescopic support rod 2, the second telescopic support rod 4, and the telescopic adjustment rod 202, which can be used to lock the length of the first telescopic support rod 2, the second telescopic support rod 4, and the telescopic adjustment rod 202.

[0038] Furthermore, a motor is installed on the outer side of the bushing 602 on the same side, and the output shaft of the motor is connected to the shaft center of the shaft head 6031 to drive the shaft head 6031 to rotate. At the same time, when the adjusting screw 6021 moves the bushing 602 up and down inside the guide groove B601, the motor will also move accordingly. The motor is electrically connected to an external power supply.

[0039] Working principle: First, the worker engages the interlocking plate 2031 with the cable tray 1. Then, the locking bolt 2032 is rotated to fix the interlocking plate 2031 to the cable tray 1. Next, the first telescopic support rod 2 is used to adjust the angle between the support plate 201 and the ground. Then, the guide groove A3 is rotated via the shaft and locked with the fastening bolts, ensuring that the guide groove A3 aligns with the cable tray 1. The guide roller 301 prevents friction between the cable and the cable tray 1, avoiding cable breakage. Next, the second telescopic support rod 4 is adjusted to align the cable management tube 5 with the guide groove A3. When the worker passes multiple cables through the cable management tube 5, the limiting bracket 6, the cable bundling cavity 7, and the guide groove A3 for cabling, the motor-driven shaft head 6031 reverses direction. Because the surface of the reverse roller 603 has grooves with a rubber layer tightly attached, the rubber layer generates slight friction with the cable, pulling the cable back taut. If the friction is too high, the adjusting screw 6021 can be rotated. The adjusting screw 6021 and the linkage sleeve 602 move up and down inside the guide groove B601 to adjust the spacing. This design can improve the tension of the cable during the wiring operation and prevent it from becoming loose. Next, when a large number of cables are needed, the reverse roller 603 has a protrusion at its end, which fits with the shaft head 6031. By removing the fastening bolts, the reverse roller 603 corresponding to the number of cables can be replaced. Finally, when the cable passes through the cable bundling cavity 7, the parallel cables can be stranded together. At the same time, the ball bearing 701 can reduce the friction of the cable and protect it. The operator can put the rubber band behind the cable bundling cavity 7 in advance. As the cable moves, the operator can pull out the rubber band and use the rubber band to tie the cable every 10-15 cm. In order for the rubber band to slide smoothly, the tapered design of the cable bundling cavity 7 can increase the rolling of the rubber band, making it easier to tie the cable and making the operation more convenient.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
