Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power pipe loading and unloading, in particular to a power pipe loading and unloading auxiliary device. BACKGROUND

[0002] The power pipe is a core pipe material for protecting the cable and guiding the laying path in the power system, and is widely used in municipal power grid reconstruction, residential area power distribution, industrial park power transmission and other engineering scenes. Its core function is to isolate underground soil corrosion, ground mechanical impact and water intrusion, to avoid cable damage caused by external environment, such as short circuit, power failure and other faults, and to protect the stability of power transmission; the common materials are MPP (modified polypropylene), CPVC (chlorinated polyvinyl chloride) or glass steel pipe. Although such materials have insulation and corrosion resistance, they are brittle and prone to cracking or deformation under impact and pressure, which directly affects the subsequent laying sealing performance and service life. In the power engineering construction process, the power pipe needs to be transported in batches from the warehouse to the construction site, and the single transport quantity is usually 50-100 (single length 6-12 meters, weight 5-20 kg). Before and after transportation, loading and unloading operations need to be completed. The current industry relies mainly on manual loading and unloading of power pipes: workers need to lift the power pipe from the ground to the truck cargo compartment (height 1.5-2.5 meters) one by one during loading, and then reverse the process to carry the pipe to the construction site storage area one by one during unloading. A full load truck requires 3-5 workers to cooperate, and the single operation time usually exceeds 2 hours, which is very low in efficiency. At the same time, manual loading and unloading also has multiple pain points: on the one hand, the brittle nature of the power pipe requires gentle handling during operation to avoid violent handling, but long-term high-intensity lifting and handling by workers can lead to improper operation due to fatigue, increasing the pipe damage rate; on the other hand, workers need to bend over and lift heavy objects repeatedly, which can cause occupational health problems such as lumbar muscle strain and joint injury during long-term operation. With the scale-up of power engineering, the contradiction between tight construction period and rising labor costs is becoming increasingly prominent, and traditional manual loading and unloading has become difficult to meet the needs of efficient construction.

[0003] Therefore, the present application provides a power pipe loading and unloading auxiliary device, which can replace manual loading and unloading of power pipes through mechanical structure, and only requires a small number of personnel to perform auxiliary operations such as pipe arrangement and positioning, which can greatly shorten the loading and unloading time, reduce the labor intensity of workers, and reduce the pipe damage caused by improper manual operation, thereby ensuring the efficiency and cost control of power engineering construction. SUMMARY

[0009] Further, a bottom bracket is further included, the bottom bracket is in the form of a tray, and a forklift can be inserted into the bottom bracket for carrying, the bottom of the bottom bracket is provided as a whole steel plate, and the supporting rod and the inclined rod are fixed to the bottom bracket through a plurality of connecting rods.

[0010] Further, a vertical column is installed at the upper end of the bottom bracket, a rotating shaft at one end of the profile plate is installed on the vertical column through a bearing seat, and a lifting mechanism is hingedly arranged at the other end of the profile plate.

[0011] Further, the lifting mechanism comprises a U-shaped frame hingedly connected with the rotating shaft at the end of the profile plate, a pair of hydraulic rods are fixedly arranged at the bottom of the U-shaped frame, and a base hingedly connected with the bottom of the hydraulic rods is welded and fixed above the bottom bracket.

[0012] Further, a rotating seat is fixed at the bottom of the hydraulic rod, the base comprises a pair of fixed columns welded and fixed above the bottom bracket, a circular shaft is fixed between the two fixed columns, and the circular shaft passes through a circular hole in the rotating seat to form a rotating connection.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] This embodiment provides an auxiliary device for loading and unloading power pipes, mainly designed as a mechanical structure to replace manual labor in the loading and unloading of power pipes. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-8 Please provide a detailed explanation: Example

[0021] An auxiliary device for loading and unloading power pipes includes an inclined conveying unit 1 for transporting pipes from a lowest point to a highest point. At the lowest point of the conveying unit 1 is a transition mechanism 2 for receiving the pipes to the ground during unloading or for assisting in pushing the pipes onto the conveying unit 1 during loading. At the highest point of the conveying unit 1 is a temporary storage unit 3 for guiding the pipes onto the conveying unit 1 during unloading or for temporarily receiving the pipes during loading. The conveying unit 1 has the following structure: it includes multiple rotating shafts 101 arranged in a straight line, all inclined in shape. Gears 102 are fixedly mounted on the rotating shafts 101. The gears 102 located on the same vertical plane mesh with the same chain 103, and the number of chains 103 is not less than a certain amount. The system consists of three chains 103, each with multiple L-shaped support frames 104 welded to its sides. The horizontal section of each support frame 104 supports the bottom of the pipe, while the vertical section blocks the pipe from sliding off the chain 103. This allows the pipe to move as the chain 103 rotates. The system also includes multiple profile plates 105, with rotating shafts 101 rotatably mounted on them using bearings, forming a unified conveying structure. During operation, the multiple rotating shafts 101 are arranged in a line to form an inclined conveying path. Gears 102 mesh with the chain 103 to ensure synchronous transmission. The support frames 104 are welded to the sides of the chain 103 and pass through as the chain 103 circulates. The horizontal support and vertical blocking sections stably carry the pipe, achieving continuous mechanical conveying from low to high. Compared to manual lifting of each pipe individually, the conveying time for a single pipe is significantly reduced, overcoming the limitation that efficiency is determined by the intensity of manual labor.

[0022] In this embodiment, please refer to Figure 1 , Figure 6 , Figure 8 This section details the specific structure for unloading pipes from a truck. The transition mechanism 2 includes multiple spoon-shaped receiving rods 21 spaced apart between adjacent chains 103. Multiple support frames 104 support the pipes as they move downwards to a lower position, where they are collectively supported by the multiple receiving rods 21. The spoon-shaped end of the receiving rods 21 is welded with a downward-sloping bar 22, which guides the pipes rolling down from the receiving rods 21 to the ground. During operation, the support frames 104 support the pipes as they descend along the conveying unit 1. Upon reaching the lower point, the pipes are laid flat and transitioned to the spoon-shaped receiving rods 21 of the transition mechanism 2. Simultaneously, the pipes slide from the spoon-shaped end of the receiving rods 21 to the inclined bar 22 and roll naturally along the inclined bar 22 to the ground stacking area. This allows workers to simply arrange the pipes on the ground, reducing labor intensity.

[0023] In this embodiment, please refer to Figures 1 to 3 , Figure 6 , Figure 8This section details the scenario of loading pipes one by one from the warehouse. At this time, two workers are standing on the truck. Specifically, the temporary storage unit 3 includes multiple receiving bends 31, which are positioned between two adjacent chains 103. Both ends of the multiple receiving bends 31 are constructed with upward-facing limit hooks 32. When the support frame 104 supports the pipes and moves upward to a high position, the multiple receiving bends 31 jointly receive the pipes and roll them to the hook ends. During operation, the support frame 104 rises along the inclined conveyor unit 1 with the chain 103. When it reaches the high point, the chain 103 turns around the top rotating shaft 101 gear 102, and the posture of the support frame 104 changes from vertical section blocking outwards to vertical section releasing inwards. Under the action of gravity, the pipes slide out of the support frame 104 and fall onto the receiving bends 31 of the temporary storage unit 3. At the same time, the receiving bends 31 are located between adjacent chains 103. The pipe rolls obliquely along the arc-shaped surface of the receiving bend 31 to the end limiting hook 32 for temporary storage. At this time, two workers on the vehicle, one on each side, move the pipe onto the vehicle for stacking. To facilitate repositioning, a base bracket 4 is included. The base bracket 4 is pallet-shaped and can be inserted and moved by a forklift. The bottom of the base bracket 4 is made of a single piece of steel plate 5, which provides a low center of gravity. The receiving rod 21 and the diagonal rod 22 are fixed to the base bracket 4 by multiple connecting rods 6. A mounting plate 12 is welded to the side of the base bracket 4. A diesel engine 13 is mounted on the mounting plate 12. The output shaft of the diesel engine 13 is connected to a manual gearbox 14 mounted on the mounting plate 12. The output shaft of the manual gearbox 14 is connected to the rotating shaft 101 located at the end of the profile plate 105 via a chain drive structure 15. It should be noted that the chain drive structure 15 here is a transmission structure in which the chain 103 and the gear 102 cooperate, which is commonly used for power transmission, such as the power transmission of tractors. In addition to adjusting the speed, the manual gearbox 14 here is also used to control the forward and reverse rotation. In specific operation, the power output of the diesel engine 13 is adjusted by the manual gearbox 14 and then the speed and direction are switched through the gear 102 group. The power is transmitted to the end shaft 101 of the mold plate 105 by the chain drive structure 15. The gear 102 on the shaft 101 meshes with the chain 103, driving all the shaft 101 gears 102 in the same vertical plane to rotate synchronously, so that multiple chains 103 move in parallel, and finally drive the L-shaped support frame 104 to circulate with the chain 103. The forward and reverse rotations correspond to the loading and unloading directions. Example

[0024] This embodiment adds the following technical solution based on embodiment 1: To adapt to vehicles of different heights, a column 7 is installed on the upper end of the base bracket 4. A rotating shaft 101 located at one end of the molded plate 105 is installed on the column 7 via a bearing seat 8. A lifting mechanism 9 is hinged to the other end of the molded plate 105. The bottom end of the lifting mechanism 9 is hinged to the base bracket 4. The lifting mechanism 9 includes a U-shaped frame 91 hinged to the rotating shaft 101 located at the end of the molded plate 105. A pair of hydraulic rods 92 are fixedly installed at the bottom of the U-shaped frame 91. A base 93 hinged to the bottom of the hydraulic rods 92 is welded and fixed to the upper part of the base bracket 4. A rotating seat 10 is fixed to the bottom of the hydraulic rods 92. The base 93 includes a pair of fixed columns 931 welded and fixed to the upper part of the base bracket 4. A round shaft 932 is fixed between the two fixed columns 931. The round shaft 932 passes through the round hole 11 on the rotating seat 10 to form a rotatable connection. It should be noted that this application provides a hydraulic pump to provide power for the hydraulic rods 92. Those skilled in the art can understand... Therefore, without further explanation, during operation, when the hydraulic rod 92 of the lifting mechanism 9 extends or retracts, it drives the U-shaped frame 91 to rise or fall, causing the template 105 to rotate around the hinge point with the column 7, thereby changing the tilt angle of the conveying unit 1 and adjusting the height of the high point. Furthermore, the bottom of the hydraulic rod 92 is rotatably connected to the round shaft 932 of the base 93 through the rotating seat 10, ensuring that the hydraulic rod 92 adapts to the angle change of the template 105, avoiding structural jamming, and achieving matching with the height of the truck cargo box. It should be noted that the adjusted height is just high enough for workers standing on the vehicle to be able to carry the pipes located on the receiving bend 31, so as to facilitate stacking. At the same time, multiple receiving bends 31 are welded to the same bracket 16, and the bracket 16 is welded to the side of the U-shaped frame 91. A whole receiving plate 17 is welded to the upper surface of the multiple receiving bends 31. The receiving plate 17 is constructed with a clearance groove to avoid the support frame 104. The whole receiving plate 17 is designed to increase the contact area of ​​the pipes falling onto the receiving bends 31, avoiding the instantaneous collapse of the pipes upon falling.

[0025] Working principle and usage process of this invention: Step 1: Using a forklift, insert the pallet structure of the base bracket 4 to move the entire device to the side of the truck. Adjust the tilt angle of the conveying unit 1 according to the height of the truck bed by operating the lifting mechanism 9: activate the hydraulic rod 92 to extend and retract, causing the profile plate 105 to rotate around the hinge point with the column 7, so that the highest point of the conveying unit 1 is level with approximately half the height of the truck bed. This position facilitates pipe handling by workers.

[0026] Step 2: Start the diesel engine 13 and adjust the speed or switch the direction using the manual gearbox 14. When loading, switch to "forward" gear and the chain 103 will drive the support frame 104 from the low point to the high point. When unloading, switch to "reverse" gear and the chain 103 will drive the support frame 104 from the high point to the low point.

[0027] Step 3: During loading, 1-2 workers place the ground power pipes horizontally on the spoon-shaped receiving rod 21. As the chain 103 rotates, the support frame 104 can carry the pipes away. When they reach the receiving bend 31 at the top, the workers above take them down and stack them. During unloading: Workers place the pipes horizontally on the receiving bend 31 of the temporary storage unit 3 from inside the cargo box. They wait for the support frame 104 to support the pipes and lower them along the conveying unit 1. When they reach the lowest point, the pipes are smoothly transferred to the spoon-shaped receiving rod 21 of the transition mechanism 2. At the same time, the pipes slide from the spoon end of the receiving rod 21 to the inclined rod 22 and roll naturally along the inclined rod 22 to the ground stacking area. Workers only need to arrange them on the ground.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
