Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically, to a cable laying guidance device in densely packed building pipeline areas. Background Technology

[0002] Dense pipeline areas refer to narrow spaces where various pipelines and cables are concentrated, such as underground pipe corridors, equipment mezzanines, or the interior of ceilings. When laying new cables in such areas, operators usually need to remotely control traction equipment to move along a pre-set complex path, thereby gradually pulling the cable from the cable reel to the target location.

[0003] Existing technologies often use manual binding with wire or ordinary clamps for fixing. When the path bends or obstacles cause a sudden increase in traction, the wire fixing points are prone to loosening, and ordinary clamps often slip due to insufficient clamping force, causing the cable to fall off at critical locations and interrupting the laying operation. In addition, the cable clamping operation and safety locking of existing methods are separated, requiring operators to perform them step by step, which is not only inefficient, but also poses a risk of accidental cable loosening due to the omission of the locking step. It cannot meet the stringent requirements for laying reliability and operational safety in dense pipeline areas. Utility Model Content

[0004] The purpose of this invention is to provide a cable laying guidance device in densely packed building pipeline areas to solve the problems mentioned in the background art.

[0005] To address the above problems, this utility model aims to provide a cable laying guidance device for densely piped areas in buildings, including a remote-controlled vehicle. A fixing module is provided on one side of the remote-controlled vehicle. The fixing module includes an assembly platform fixedly installed on the side of the remote-controlled vehicle. A guide rail is fixedly installed on the upper side wall of the assembly platform. A pressure block is slidably disposed inside the guide rail. Slider blocks are fixedly installed on both sides of the pressure block. Inclined grooves are formed on the guide rail at positions corresponding to the two sliders. The sliders are slidably disposed within the corresponding inclined grooves. A channel is formed between the lower side wall of the pressure block and the bottom side of the guide rail. A vertical plate is fixedly installed on the upper side wall of the assembly platform between the guide rail and the remote-controlled vehicle. A circular hole is formed on the vertical plate. A clamping mechanism is disposed inside the circular hole. A locking mechanism is provided on one side of the clamping mechanism. The locking mechanism is used to fix the pressure block inside the guide rail. When the cable passes through the channel and enters the circular hole, the clamping mechanism clamps and fixes the cable. Simultaneously, the clamping mechanism drives the locking mechanism to release the locking mechanism from locking the pressure block, causing the lower side wall of the pressure block to make tight contact with the top of the cable.

[0006] As a further improvement to this technical solution, the clamping mechanism includes a cylinder rotatably mounted on the inner wall of the circular hole. The cylinder has several hollowed-out grooves arranged in a circular array, and the hollowed-out grooves are located on the side of the upright plate near the guide rail. A sliding sleeve is rotatably mounted inside the hollowed-out grooves.

[0007] As a further improvement to this technical solution, a rotating arm is slidably provided inside the sliding sleeve. The end of the rotating arm away from the axis of the cylinder is rotatably mounted on the vertical plate, and a rubber wheel is rotatably mounted on the end of the rotating arm close to the cylinder.

[0008] As a further improvement to this technical solution, a gear is coaxially fixedly installed at one end of the cylinder, a movable plate is vertically slidably installed on the side of the upright plate away from the guide rail, and a rack is fixedly installed on one side of the movable plate, the rack meshing with the gear.

[0009] As a further improvement to this technical solution, a threaded rod is rotatably installed on the side of the upright plate away from the guide rail. Guide rods are vertically fixedly installed on both sides of the threaded rod. The movable plate is slidably mounted on the two guide rods. An internal threaded sleeve is fixedly installed on the movable plate and is threadedly connected to the threaded rod.

[0010] As a further improvement to this technical solution, a guide groove is provided on the upright plate, and the locking mechanism includes an extension frame that is slidably disposed inside the guide groove. One end of the extension frame is fixedly connected to the movable plate, and a locking tongue is fixedly installed on the other end of the extension frame.

[0011] As a further improvement to this technical solution, a first locking groove is provided on the top of the guide rail, and a second locking groove is provided on the top of the pressure block. When the clamping mechanism does not clamp the cable, the axis of the first locking groove and the axis of the second locking groove are collinear, and the locking tongue is engaged in the interior of the first locking groove and the second locking groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This cable laying guide device in densely piped building areas operates as follows: When the cable passes through the channel and the circular hole in sequence, the operator rotates the threaded rod to drive the moving plate upward, causing the rack and pinion to mesh with the gear, making the cylinder rotate and pushing the rotating arm to retract inward. This allows all the rubber wheels to clamp the cable together, increasing friction and preventing the cable from slipping or being damaged during laying. At the same time, in the initial state, the locking mechanism engages the locking tongue with the guide rail and the locking slot of the pressure block, fixing the pressure block in the guide rail and keeping the channel open for cable adjustment. When the clamping mechanism fixes the cable, the moving plate moves upward and, through the extension frame, moves the locking tongue out of the locking slot, releasing the locking of the pressure block. Under the action of gravity, the pressure block moves diagonally downward along the inclined groove, pressing the cable against the bottom side of the guide rail, forming a self-locking mechanism. This means that when the cable is pulled by a remote-controlled vehicle, the increased pulling force actually increases the downward pressure of the pressure block, thus achieving reliable cable fixation by both the clamping mechanism and the pressure block, preventing it from falling off.

[0015] 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.

[0016] Example 1 Please see Figure 1 As shown, the purpose of this embodiment is to provide a cable laying guidance device in a densely packed building pipeline area, including a remote control vehicle 1. The remote control vehicle 1 is equipped with a camera device that can capture the image in front of the vehicle in the direction of travel in real time, and transmit the image to an external control console through a wireless transmitter. The operator can remotely control the forward movement and turning of the remote control vehicle 1 through the control console based on this real-time image, and accurately control its travel route.

[0017] A fixing module 2 is provided on one side of the remote control vehicle 1. The fixing module 2 is used to fix the cable 3 to be laid. Before the laying operation begins, the cable 3 is pre-wound onto a take-up reel, which is fixed at the starting point of the wiring. The operator first fixes one end of the cable 3 to the remote control vehicle 1 through the fixing module 2, and then remotely controls the remote control vehicle 1 to move along the predetermined path. During this process, the remote control vehicle 1 pulls the cable 3 to make it unwind smoothly from the take-up reel. After the remote control vehicle 1 reaches the end position, the cable 3 is removed from the fixing module 2, thus completing the laying operation of this section of cable 3.

[0018] It should be noted that the camera equipment, wireless transmission equipment, remote control vehicle 1 and control console involved in this embodiment all adopt existing mature technologies, and their specific structures and working principles will not be described in detail.

[0019] The structure of fixed module 2 is detailed below, referring to... Figures 2-6The fixing module 2 includes an assembly platform 21 fixedly installed on one side of the remote control vehicle 1. A guide rail 25 is fixedly installed on the upper side wall of the assembly platform 21. A pressure block 26 is slidably arranged inside the guide rail 25. The bottom of the pressure block 26 is machined with a serrated groove to enhance the friction between it and the cable 3. A slider 262 is fixedly installed on both sides of the pressure block 26. An inclined groove 252 is opened on the guide rail 25 at the position corresponding to the two sliders 262. The inclined groove 252 is oriented with the end away from the remote control vehicle 1 being lower and the end closer to the remote control vehicle 1 being higher. The slider 262 is slidably arranged inside the corresponding inclined groove 252, restricting the pressure block 26 to tilt and move only along the extension direction of the inclined groove 252. A channel is formed between the lower side wall of the pressure block 26 and the bottom side inside the guide rail 25 for the cable 3 to pass through.

[0020] A vertical plate 22 is fixedly installed on the side wall of the assembly table 21 between the guide rail 25 and the remote control vehicle 1, as shown in the figure. Figure 10 The upright plate 22 has a circular hole 221. A clamping mechanism 23 is installed inside the circular hole 221. A locking mechanism 24 is installed on one side of the clamping mechanism 23. The locking mechanism 24 is used to fix the pressure block 26 inside the guide rail 25 in the initial state. At this time, the distance between the pressure block 26 and the bottom side of the guide rail 25 is greater than the outer diameter of the cable 3. The cable 3 can move freely in the channel, which makes it easy for the operator to adjust the extension length of the cable 3 and ensure that the clamping mechanism 23 can clamp the effective section of the cable 3.

[0021] When cable 3 passes through the channel and enters the interior of the circular hole 221, clamping mechanism 23 clamps and fixes cable 3. At the same time, clamping mechanism 23 drives locking mechanism 24 to release locking mechanism 24 from locking block 26. At this time, under the action of gravity, block 26 moves obliquely downward along inclined groove 252, pressing cable 3 into the bottom side of guide rail 25, so that the lower side wall of block 26 is in close contact with the top of cable 3, and the bottom of cable 3 is in close contact with the bottom side of guide rail 25.

[0022] When the remote control vehicle 1 pulls the cable 3 forward, the cable 3 is subjected to a backward pulling force. Due to the friction between the cable 3 and the pressure block 26, this pulling force is transmitted to the pressure block 26, causing it to tend to move backward. Since the slider 262 is slidably set in the inclined groove 252 with a higher front and lower rear, the pressure block 26 is forced to press the cable 3 downward by the inclined groove 252 structure while moving backward, thus achieving self-locking. The reason is that the inclined structure of the inclined groove 252 converts the horizontal movement of the pressure block 26 into vertical downward pressure. The greater the pulling force, the greater the downward pressure of the pressure block 26, thus forming a clamping effect that gets tighter as it is pulled. This mechanism effectively prevents the cable 3 from accidentally falling off the fixing module 2 due to slippage during the laying process.

[0023] The structure of clamping mechanism 23 is described in detail below, with reference to... Figures 7-10The clamping mechanism 23 includes a cylinder 231 rotatably mounted on the inner wall of the circular hole 221. A plurality of perforated slots 232 are arranged in a circular array on the cylinder 231, with the slots 232 located on the side of the upright plate 22 near the guide rail 25. A sliding sleeve 233 is rotatably mounted inside the perforated slot 232, and a rotating arm 234 is slidably mounted inside the sliding sleeve 233. One end of the rotating arm 234 away from the axis of the cylinder 231 is rotatably mounted on the upright plate 22, and a rubber wheel 235 is rotatably mounted on the end of the rotating arm 234 near the cylinder 231. A gear 236 is coaxially fixedly mounted on one end of the cylinder 231. A movable plate is vertically slidably mounted on the side of the upright plate 22 away from the guide rail 25. 237. A rack 2371 is fixedly installed on one side of the movable plate 237. The rack 2371 meshes with the gear 236. A threaded rod 238 is rotatably installed on the side of the upright plate 22 away from the guide rail 25. Guide rods 239 are vertically fixedly installed on both sides of the threaded rod 238 on the upright plate 22. The movable plate 237 is slidably mounted on the two guide rods 239. The axis of the threaded rod 238 is parallel to the axis of the guide rod 239. The guide rods 239 restrict the movement of the movable plate 237 in the vertical direction. An internal threaded sleeve is fixedly installed on the movable plate 237. The internal threaded sleeve is threadedly connected to the threaded rod 238. An external hexagonal block is coaxially fixedly installed on the upper end of the threaded rod 238.

[0024] When using this device, a protective cover can be installed on the side of the upright plate 22 away from the guide rail 25 to cover the threaded rod 238, gear 236 and rack 2371, so as to prevent dust and impurities from adhering to the threaded rod 238, gear 236 and rack 2371 during the movement of the remote control car 1, which would affect the normal operation of the clamping mechanism 23.

[0025] After the cable 3 is passed through the positions between all the rubber wheels 235, the operator uses an electric wrench to turn the outer hexagonal block, driving the threaded rod 238 to rotate. Through the engagement of the threaded rod 238 and the inner threaded sleeve, the moving plate 237 moves vertically along the guide rod 239. The moving plate 237 drives the rack 2371 to move synchronously. The rack 2371 drives the cylinder 231 to rotate through the meshing transmission with the gear 236. The cylinder 231 drives all the sliding sleeves 233 to move synchronously. The sliding sleeves 233 then drive the rotating arm 234 to rotate around the rotation point between itself and the vertical plate 22, so that the rotating arm 234 drives the rubber wheels 235 to move towards or away from the axis of the cylinder 231.

[0026] When the moving plate 237 moves vertically upward, the rotating arm 234 drives the rubber wheel 235 to rotate in a direction closer to the axis of the cylinder 231, so that all the rubber wheels 235 together clamp and fix the cable 3. The rubber wheel 235 is made of rubber, which can not only enhance the friction between the cable 3 and the outer sheath to prevent slippage during the laying process, but also reduce the damage to the surface of the cable 3.

[0027] A guide groove 222 is provided on the upright plate 22. The guide groove 222 provides installation space for the locking mechanism 24. The structure of the locking mechanism 24 is described in detail below, referring to... Figures 7-10 The locking mechanism 24 includes an extension frame 241 that is slidably disposed inside the guide groove 222. One end of the extension frame 241 is fixedly connected to the movable plate 237, and the other end of the extension frame 241 is fixedly installed with a locking tongue 242.

[0028] Reference Figures 4-6 The top of the guide rail 25 is provided with a first locking groove 251, and the top of the pressure block 26 is provided with a second locking groove 261. When the clamping mechanism 23 does not clamp the cable 3, the axis of the first locking groove 251 and the axis of the second locking groove 261 are collinear, and the locking tongue 242 is inserted into the interior of the first locking groove 251 and the second locking groove 261, thereby restricting the pressure block 26 and the slider 262 from moving along the extension direction of the inclined groove 252, and realizing the initial fixation of the pressure block 26.

[0029] When the moving plate 237 moves vertically upward, it will drive the locking tongue 242 to move upward synchronously through the extension frame 241. When all the rubber wheels 235 have completed clamping and fixing the cable 3, the locking tongue 242 has also completely moved out of the first locking groove 251 and the second locking groove 261, thereby releasing the lock on the pressure block 26. After that, the self-locking mechanism of the pressure block 26 can take effect.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
