Abstract
Description
Technical Field
[0001] This utility model relates to the field of power crossarm manufacturing technology, specifically to a power crossarm manufacturing and forming equipment. Background Technology
[0002] A power crossarm is an angle iron fixed horizontally at the top of a utility pole, used to install insulators and support overhead power lines. It is a crucial component of overhead transmission and distribution lines, playing a key role in bearing and distributing the load of the power lines. In terms of shape, power crossarms are generally long and narrow. Common types include angle iron crossarms and channel steel crossarms. Angle iron crossarms are made of angle steel and have a simple shape, usually in the form of a straight line or an A-frame. Straight crossarms are mainly used on straight poles, while A-frame crossarms are used on tension poles and other poles that need to withstand greater tension. Channel steel crossarms are made of channel steel and have a relatively strong load-bearing capacity, used in lines with high strength requirements. Power crossarms are mainly made of metal materials, such as ordinary carbon steel and low-alloy steel. These materials have high strength and good conductivity, meeting the mechanical and electrical requirements of power transmission. Meanwhile, to prevent metal crossarms from rusting and corroding, their surfaces are usually treated with anti-corrosion measures, such as hot-dip galvanizing. The zinc layer forms a protective film on the crossarm surface, preventing oxygen and moisture from contacting the metal substrate, thus extending the crossarm's service life. Electric crossarms are installed at appropriate locations on utility poles, generally near the top. Their main function is to provide a mounting base for insulators. Insulators are used to suspend overhead power lines, insulating the lines from the poles and ensuring safe power transmission. Crossarms distribute the load of the power lines evenly across the poles and maintain a certain distance between the lines, preventing collisions and short circuits. In different line types, such as high-voltage transmission lines and low-voltage distribution lines, the dimensions and strength parameters of the crossarms are designed and adjusted according to factors such as the voltage level, number of conductors, and span of the line.
[0003] The existing equipment for manufacturing and forming power crossarms has the following drawbacks: If protrusions are not quickly removed during the forming process of power crossarms, the surface flatness of the crossarm will not meet the requirements. Protrusions that are not removed during the forming process will form stress concentration points on the crossarm. In subsequent use, when the crossarm is subjected to external loads (such as the weight of the conductor, wind force, etc.), the stress concentration area is more likely to crack. Utility Model Content
[0004] The purpose of this invention is to provide a power crossarm manufacturing and forming equipment to solve the problem in the background technology that the inability to quickly clean protrusions leads to the crossarm surface flatness not meeting the requirements and affecting the insulator bonding.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a power crossarm manufacturing and forming equipment, including a processing table, a dust collection box on the top of the processing table, a cylinder on one side of the processing table, a sliding seat at the end of the cylinder, and a power crossarm body inserted into the other side of the processing table;
[0006] The processing table is equipped with a cleaning component for cleaning protrusions on the surface of the power crossarm body;
[0007] The processing table is equipped with an adsorption component to adsorb the generated dust;
[0008] The cleaning component includes a groove on the upper surface of the processing table, a slider horizontally slidably connected in the groove, a first motor on one side of the processing table, a rotating shaft at the end of the first motor, the end of the rotating shaft threadedly connected to the slider and rotatably connected to the other side of the processing table, a polishing block on the top of the slider, a clamping plate inside the polishing block, a threaded hole on the polishing block, a drive shaft threadedly connected in the threaded hole and rotatably connected to the clamping plate, a friction cloth adhered to the inner wall of the polishing block and the clamping plate, a first insertion groove on the processing table, and a second insertion groove on the sliding seat.
[0009] Preferably, the adsorption assembly includes an isolation plate disposed inside the dust collection box, two sets of ventilation sleeves disposed on the isolation plate, a second motor disposed inside the dust collection box and located at one end of the isolation plate, a fan disposed at the end of the second motor, a filter bag inserted inside the dust collection box and located at the other end of the isolation plate, and an adsorption port opened on the dust collection box.
[0010] Preferably, a shock-absorbing support is provided inside the processing table, and the shock-absorbing support is located at the bottom of the first motor.
[0011] Preferably, the sliding seat is located on the upper surface of the machining table, and the rotating shaft is located at the bottom of the sliding seat.
[0012] Preferably, the dust collection box has a through groove and two sets of through grooves, and filter bags are inserted into the through grooves.
[0013] Preferably, both the first and second insertion slots have gaskets bonded inside.
[0014] Preferably, the clamping plates are provided in three sets and are arranged in a Z-shape within the polishing block.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In this utility model, one end of the power crossarm body is inserted into the first insertion slot, and the other end of the power crossarm body passes through the polishing block. The drive shaft is rotated, and the drive shaft rotates in the threaded hole to drive the clamping plate, so that the clamping plate fits against the surface of the power crossarm body. The clamping plate is provided in three sets in a Z shape, so that the shape of the clamping plate can fit well against the surface of the power crossarm and provide stable support force when clamping the power crossarm. The drive cylinder pushes the sliding seat to move horizontally on the processing table, and inserts the end of the power crossarm body into the second insertion slot, thus completing the rapid clamping of the power crossarm body. The first motor is driven. The first motor is a stepper motor. The stepper motor drives the rotating shaft to reciprocate, so that the slider is subjected to force and slides horizontally back and forth in the sliding groove, thereby cleaning the surface of the power crossarm body with the friction cloth in the polishing block.
[0017] 2. In this utility model, by driving a second motor, the second motor drives a fan. The high-speed rotation of the fan creates a negative pressure inside one end of the isolation plate, forming a partial vacuum inside the dust collection box. The pressure difference between the inside and outside draws in external air, allowing impurities generated during cleaning of the protrusions to enter through the suction port of the dust collection box and adhere to the surface of the filter bag. Two sets of filter bags are provided, which can be replaced back and forth to prevent impurities from being adsorbed from the ventilation sleeve into the other end of the isolation plate when replacing a single set of filter bags, thus affecting the normal operation of the second motor.

[0022] 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.
[0023] Example 1
[0024] Please see Figure 1 - Figure 3 The diagram shows a power crossarm manufacturing and forming equipment, including a processing table 1, a dust collection box 2 on the top of the processing table 1, a cylinder 3 on one side of the processing table 1, a sliding seat 4 at the end of the cylinder 3, and a power crossarm body 5 inserted into the other side of the processing table 1.
[0025] The processing table 1 is equipped with a cleaning component 6, which is used to clean the protrusions on the surface of the power crossarm body 5;
[0026] The processing table 1 is equipped with an adsorption component 7, which is used to adsorb the generated dust.
[0027] The cleaning component 6 includes a groove 609 formed on the upper surface of the processing table 1. A slider 604 is horizontally slidably connected in the groove 609. A first motor 606 is provided on one side of the processing table 1. A rotating shaft 603 is provided at the end of the first motor 606. The end of the rotating shaft 603 is threadedly connected in the slider 604 and rotatably connected to the other side of the processing table 1. A polishing block 605 is provided on the top of the slider 604. A clamping plate 61 is provided in the polishing block 605. A threaded hole 62 is provided on the polishing block 605. A drive shaft 63 is threadedly connected in the threaded hole 62 and rotatably connected in the clamping plate 61. A friction cloth 608 is adhered to the inner wall of the polishing block 605 and the clamping plate 61. A first insertion groove 601 is provided on the processing table 1, and a second insertion groove 602 is provided on the sliding seat 4.
[0028] In this solution, when it is necessary to quickly clean the surface of the power crossarm body 5, one end of the power crossarm body 5 is inserted into the first insertion slot 601, and the other end of the power crossarm body 5 passes through the polishing block 605. The drive shaft 63 is rotated, and the drive shaft 63 rotates in the threaded hole 62, thereby driving the clamping plate 61, so that the clamping plate 61 is attached to the surface of the power crossarm body 5. The cylinder 3 is driven (the cylinder 3 converts the pressure energy of compressed air into mechanical energy, driving the piston to make linear reciprocating motion in the cylinder 3). The cylinder 3 pushes the sliding seat 4 to move horizontally on the processing table 1, and inserts the end of the power crossarm body 5 into the second insertion slot 602, completing the rapid clamping of the power crossarm body 5. The first motor 606 is driven, and the first motor 606 is a stepper motor (a stepper motor is a type of motor that converts electrical pulse signals into angular displacement or linear displacement). The magnetic device rotates the motor by a fixed angle (called the step angle) for each input electrical pulse. Its speed and stopping position depend only on the frequency and number of pulse signals. The stepper motor drives the rotating shaft 603 to reciprocate, causing the slider 604 to slide horizontally back and forth in the groove 609. This allows the friction cloth 608 (nylon abrasive cloth with nylon fiber as the base and special abrasive particles on the surface, which has good flexibility and can conform to the shape of the crossarm surface, and can clean well even if the crossarm surface has a certain curvature or irregular shape) in the polishing block 605 to clean the surface of the power crossarm body 5, thereby cleaning the protrusions on the power crossarm surface. The cleaning component 6 solves the problem that the inability to quickly clean protrusions will lead to the crossarm surface flatness not meeting the requirements and affecting the insulator bonding.
[0029] Furthermore, the adsorption assembly 7 includes an isolation plate 701 disposed inside the dust collection box 2, two sets of ventilation sleeves 702 disposed on the isolation plate 701, a second motor 703 disposed inside the dust collection box 2 and located at one end of the isolation plate 701, a fan 704 disposed at the end of the second motor 703, a filter bag 707 inserted inside the dust collection box 2 and located at the other end of the isolation plate 701, and an adsorption port 705 opened on the dust collection box 2;
[0030] Specifically, during cleaning, the second motor 703 is driven, which in turn drives the fan 704. The fan 704 rotates at high speed, creating a negative pressure inside one end of the isolation plate 701, forming a partial vacuum inside the dust collection box 2. The pressure difference between the inside and outside is used to draw in external air, allowing impurities generated during cleaning of the protrusions to enter through the suction port 705 of the dust collection box 2 and then adhere to the surface of the filter bag 707.
[0031] Furthermore, a shock-absorbing support 607 is provided inside the processing table 1, and the shock-absorbing support 607 is located at the bottom of the first motor 606.
[0032] Specifically, the first motor 606 will generate vibrations during operation. This is caused by factors such as the rotation of the rotor inside the motor, the action of electromagnetic force, and the operation of mechanical parts. The vibration damping support 607 can effectively absorb and isolate these vibrations. Most of the vibration energy is absorbed by the elastic elements inside (such as springs, rubber pads, etc.), thereby reducing the vibration amplitude transmitted to the outside.
[0033] Furthermore, the sliding seat 4 is located on the upper surface of the processing table 1, and the rotating shaft 603 is located at the bottom of the sliding seat 4;
[0034] Specifically, this prevents the sliding seat 4 from contacting the rotating shaft 603 during movement, which would affect the rotation of the rotating shaft 603 and the treatment of the protrusions on the surface of the power crossarm body 5 by the polishing block 605 and the clamping plate 61.
[0035] Furthermore, the dust collection box 2 has a through groove 706 and two sets of through grooves 706, and a filter bag 707 is inserted into the through groove 706.
[0036] Specifically, there are two sets of filter bags 707, which can be replaced back and forth to prevent impurities from being adsorbed from the ventilation sleeve 702 into the other end of the isolation plate 701 when a single set of filter bags 707 is replaced, thus affecting the normal use of the second motor 703.
[0037] Furthermore, both the first insertion slot 601 and the second insertion slot 602 have gaskets 610 bonded inside;
[0038] Specifically, the bonded gasket 610 cushions the power crossarm body 5 to prevent damage caused by impact when the sliding seat 4 moves and the power crossarm body 5 is inserted into the second insertion slot 602.
[0039] Furthermore, the clamping plates 61 are provided in three sets and are arranged in a Z-shape within the polishing block 605;
[0040] Specifically, the clamping plates 61 are provided in three sets in a Z-shape, so that the shape of the clamping plates 61 can fit well against the surface of the power crossarm and provide stable support when clamping the power crossarm.
