Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying device for substations. Background Technology

[0002] According to the patent document with publication number CN221380253U, the cable reel is placed between two limiting bars. Pushing the cable reel causes it to roll to the right until its central axis is above the U-shaped frame. A drive motor drives a rotating component to wind a steel wire rope, which in turn causes the limiting component to contact the cable reel and lift it to a height suitable for cable laying. The cable on the reel is then passed through the bottom of the rotating rod and the rubber wheel, and the push rod can be pushed to start the laying operation. This prevents the need for a crane or a lot of manpower to lift the cable reel and place it in the U-shaped groove before laying the cable. It also avoids the situation where the cable reel is suspended in the air due to the lack of limiting during placement, which could easily cause it to sway and pose a safety hazard to the workers.

[0003] The patent document describes how, when cables on a cable reel are passed sequentially between the bottom of the rotating rod and the rubber wheel, the number and spacing of cables used during cable laying vary depending on the different construction requirements of different substations. The rotating rod and the rubber wheel are a single structure and cannot be adjusted according to actual needs, causing inconvenience in cable laying. Utility Model Content

[0004] The purpose of this utility model is to provide a substation cable laying device in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A substation cable laying device includes a placement mechanism for loading and unloading cable reels and a spacing adjustment mechanism for adjusting the positions of multiple cables.

[0007] The placement mechanism includes a platform, with two push plates slidably connected to one side of the top of the platform. Each of the two push plates has three support plates fixed on top to support the corresponding cable reel shaft. Two cylinders for pushing the push plates are fixed on the front and rear sides of the bottom of the platform.

[0008] The adjustment mechanism includes two first vertical plates located on the other side of the top of the vehicle plate. Three rollers for supporting cables are rotatably connected to the top of the two first vertical plates. Two second vertical plates are provided on the other side of the two first vertical plates. An adjustment plate is slidably connected between the two second vertical plates. Three sliding columns are slidably connected to one side of the adjustment plate. A connecting rod is fixed to one side of each of the three sliding columns. A sliding shaft is fixed to the top of each of the three connecting rods. A support rod is fixed between the tops of the two second vertical plates.

[0009] Preferred configuration: A pusher is fixed to one side of the vehicle platform, and four wheels are rotatably connected to the bottom of the vehicle platform.

[0010] Preferably, the top of the vehicle panel has two limiting grooves for limiting the cable reel, and the telescopic end of the cylinder passes through the vehicle panel and is fixedly connected to the corresponding push plate.

[0011] Preferably, the two second vertical plates have a sliding groove on the side near the adjusting plate.

[0012] Preferably, the adjusting plate has three straight slots for adjusting the distance of the sliding shaft. The middle straight slot is vertical, and the other two straight slots are symmetrically distributed with respect to the middle straight slot. The other two straight slots are inclined.

[0013] Preferred configuration: All three sliding shafts are sleeved on the outside of the support rod, and a lead screw is threaded to the front of the adjusting plate, with a handle fixed to the top of the lead screw.

[0014] The advantages compared with the existing technology are as follows: the cables on the three cable reels are supported by three rollers respectively, and the screw is rotated by the handle. The screw drives the adjusting plate to slide in the vertical direction, so that the three sliding columns slide in the corresponding straight grooves of the adjusting plate. The sliding columns drive the connecting rod to move, and the connecting rod drives the three sliding shafts to slide on the outside of the support rod, so as to realize the distance adjustment between the three sliding shafts, meet the needs of different cable positions, and improve the convenience of cable laying.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a substation cable laying device includes a placement mechanism 1 for loading and unloading cable reels and a spacing adjustment mechanism 2 for adjusting the positions of multiple cables.

[0028] In this embodiment: the placement mechanism 1 includes a platform 101. Two push plates 102 are slidably connected to one side of the top of the platform 101. Three support plates 103 for supporting the corresponding cable reel shafts are fixed on the top of each push plate 102. Two cylinders 104 for pushing the push plates 102 are fixed on the front and rear sides of the bottom of the platform 101. Two limiting grooves for limiting the cable reels are opened on the top of the platform 101. The telescopic ends of the cylinders 104 pass through the platform 101 and are fixedly connected to the corresponding push plates 102. A pusher 105 is fixed on one side of the platform 101. Four wheels 106 are rotatably connected to the bottom of the platform 101. The three cable reels are pushed to the corresponding support plates 103 positions through the limiting grooves on the top of the platform 101. The four cylinders 104 push the corresponding push plates 102 upwards, and then the two push plates 102 drive the corresponding support plates 103 to suspend and support the three cable reels. The pusher 105 drives the platform 101 and the four wheels 106 to move to one side.

[0029] In this embodiment: the adjusting mechanism 2 includes two first vertical plates 201, located on the other side of the top of the vehicle plate 101. Three rollers 202 for supporting cables are rotatably connected to the top of the two first vertical plates 201. Two second vertical plates 203 are provided on the other side of the two first vertical plates 201. An adjusting plate 204 is slidably connected between the two second vertical plates 203. A groove is provided on the side of the two second vertical plates 203 near the adjusting plate 204. Three sliding pillars 205 are slidably connected to one side of the adjusting plate 204. A connecting rod 206 is fixed to one side of each of the three sliding pillars 205. A sliding shaft 207 is fixed to the top of each of the three connecting rods 206. The adjusting plate 204 has three straight grooves for adjusting the distance between the sliding shafts 207. The middle straight groove is vertical, and the other two... The three straight slots are symmetrically distributed with the middle slot as the center, and the other two straight slots are inclined. A support rod 208 is fixed between the tops of the two second vertical plates 203. Three sliding shafts 207 are all sleeved on the outside of the support rod 208. A lead screw 209 is threaded to the front of the adjusting plate 204. A handle is fixed to the top of the lead screw 209. The handle drives the lead screw 209 to rotate, which in turn drives the adjusting plate 204 to slide vertically. This causes the three sliding columns 205 to slide in the corresponding straight slots of the adjusting plate 204. The sliding columns 205 drive the connecting rod 206 to move, which causes the three sliding shafts 207 to slide outside the support rod 208, thereby adjusting the distance between the three sliding shafts 207. The cables on the three cable reels are supported by three rollers 202.

[0030] Working principle: Three cable reels are placed sequentially in the limiting grooves at the top of the vehicle plate 101. The three cable reels are pushed to their corresponding support plates 103. Four cylinders 104 are activated to push the corresponding push plates 102 upwards. The two push plates 102 then move the corresponding support plates 103 upwards, suspending the three cable reels. The cables on the three cable reels are placed on three rollers 202, which individually support the three cables. Turning the handle rotates the lead screw 209, which in turn causes the adjusting plate 204 to slide vertically upwards. 4. Slide within the grooves on the inner side of the two second vertical plates 203. The adjusting plate 204 slides upward, causing the three sliding columns 205 to slide within the corresponding straight grooves of the adjusting plate 204. The three sliding columns 205 drive the corresponding connecting rods 206 to move. The three connecting rods 206 drive the corresponding sliding shafts 207 to slide outside the support rod 208. The middle sliding shaft 207 remains stationary, while the sliding shafts 207 on both sides move away from each other, thereby adjusting the distance between the three sliding shafts 207 according to actual needs. Pull the pusher 105 to move the vehicle plate 101 and the four wheels 106 to one side, and begin the cable laying work.

[0031] 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 illustrative of the principles of this 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.
