Description

Technical Field

[0001] This utility model relates to the field of overhead conductor production technology, specifically to an integrated cutting and grinding equipment for overhead conductors. Background Technology

[0002] Overhead conductors, as opposed to cables, are power transmission lines that transmit electrical energy by erecting conductors at a certain height using poles and towers. The installation method for overhead conductors involves cutting the conductor to the required length, inserting it into the equipment's clamping conduit, and pressing it tightly to ensure a close contact between the conductor and the clamping conduit. Currently, the length is typically measured manually before cutting, and then the conductor is moved to a grinding station for deburring. However, this process is prone to inaccuracies due to manual measurement, and the frequent handling of conductors also increases the workload for workers. Therefore, developing an integrated cutting and grinding device for overhead conductors has become an urgent problem to be solved. Utility Model Content

A third electric push rod is vertically mounted on the upper surface of the portal frame relative to the position of the second mounting plate. The pushing end of the third electric push rod extends vertically downward into the interior of the portal frame and is screwed to the upper surface of the second mounting plate. It drives the second mounting plate to move vertically up and down inside the portal frame. The overhead conductor, after being straightened by the straightening mechanism, passes horizontally through the portal frame. After the length is measured by the length measuring mechanism, it is cut by the cutting assembly. A grinding mechanism is symmetrically provided on both sides of the portal frame relative to the cutting position of the overhead conductor.

The horizontal plane where the lower surface of the upper straightening roller is located is below the horizontal plane where the lower end surface of the first mounting plate is located, and it is necessary to ensure that the upper straightening roller and the lower straightening roller are aligned vertically and coplanarly. Then, after the upper straightening roller descends vertically and the lower straightening roller comes into close contact with the overhead conductor, the upper straightening roller and the lower straightening roller cooperate to straighten the horizontally transversely coaxial overhead conductor passing through the cylinder.

The abutment roller is vertically aligned with the support roller, and its two ends are rotatably connected to the lifting frame around its own axis via a rotating shaft, ensuring that the lifting frame does not interfere with the rotation of the abutment roller. The lower end of the roller surface of the abutment roller extends out of the lower surface of the lifting frame, and a second electric push rod is vertically provided on the upper surface of the portal frame relative to the center of the lifting frame. The pushing end of the second electric push rod extends vertically downward into the interior of the portal frame and is screwed and fixed to the upper surface of the lifting frame, thereby driving the lifting frame to move vertically up and down in the area above the support roller inside the portal frame, and ensuring that the abutment roller and the support roller are in tight contact with the upper and lower surfaces of the overhead conductor passing through the portal frame, respectively. The front end of the rotating shaft extends vertically out of the front surface of the lifting frame and is coaxially and fixedly connected to the measuring wheel arranged horizontally, ensuring that the lifting frame does not interfere with the synchronous rotation of the measuring wheel with the rotating shaft.

A fourth electric push rod is vertically arranged on the upper surface of the second fixing plate relative to the lower pressure roller. The pushing end of the fourth electric push rod extends vertically downward from the lower surface of the second fixing plate and is screwed to the upper end of the third mounting bracket, driving the third mounting bracket to move vertically up and down on the right side of the portal frame relative to the area above the lower pressure roller. An upper pressure roller matching the lower pressure roller is horizontally and longitudinally arranged at the lower end of the third mounting bracket relative to the lower pressure roller. The horizontal plane of the lower surface of the upper pressure roller is located below the horizontal plane of the lower end of the third mounting bracket. It is necessary to ensure that the upper and lower pressure rollers are aligned vertically and coplanarly.

Inside the portal frame, L-shaped plates are symmetrically arranged on both sides relative to the cut-off position of the overhead conductor. The horizontal sides of both L-shaped plates are arranged longitudinally towards the overhead conductor, and their vertical sides are both vertically upward. A fifth electric push rod is also arranged longitudinally on the front and rear outer sides of the portal frame relative to the vertical side of each L-shaped plate. The two fifth electric push rods are arranged in a straight line longitudinally, and their pushing ends move synchronously. A reinforcing rod is also inclined between the upper surface of the tail of each fifth electric push rod and the corresponding front and rear outer sides of the portal frame, thereby fixing and reinforcing the corresponding fifth electric push rod. The pushing ends of the two fifth electric push rods are arranged facing each other and extend vertically into the interior of the portal frame, respectively, and are screwed and fixed to the corresponding positions on the outer surfaces of the vertical sides of the L-shaped plates, thereby driving the two L-shaped plates to move synchronously towards or away from each other longitudinally. A third fixing plate is horizontally and longitudinally fixed on the front and rear inner sides of the portal frame relative to each L-shaped plate. Two third fixing plates are horizontally coplanar, and the distance between them is greater than the longitudinal width of the second mounting plate, without interfering with the vertical movement of the second mounting plate. A reinforcing plate is vertically installed between the front and rear inner sides of the portal frame and the lower surface of the corresponding third fixing plate, and the reinforcing plate reinforces the corresponding third fixing plate. A horizontally longitudinally arranged slide rail is symmetrically spaced on the upper surface of each third fixing plate relative to the lower surface of the horizontal edge of each L-shaped plate, and a matching slide rail is provided on the lower surface of the horizontal edge of each L-shaped plate relative to each slide rail. The sliders are designed to ensure that the length of each slider matches the longitudinal length of the horizontal side of the corresponding L-shaped plate.

The center of the grinding end is ensured to be horizontally coplanar with the center of the overhead conductor. Through the synchronous movement of the two L-shaped plates towards each other, the grinding ends of the two grinding machines form a ring that coaxially encloses the cut position of the overhead conductor, allowing the grinding machines to perform grinding operations on the cut position of the overhead conductor.

The overhead wire 1, after being straightened by the straightening mechanism, passes horizontally through the portal frame 14, and after the length is measured by the length measuring mechanism, it is cut by the cutting component 25; a grinding mechanism is symmetrically provided on both sides of the portal frame 14 relative to the cutting position of the overhead wire 1, and the cut overhead wire 1 is ground by the horizontal longitudinal movement of the two grinding mechanisms. The cutting component 25 used in this utility model is a conventional electric cutting machine. The selection of the electric cutting machine only needs to be based on factors such as the material and diameter of the overhead wire 1. Therefore, the structure and working principle of the cutting component 25 will not be described in detail here.

The output end of the motor 7 is set to the left and is connected to the driven gear 5 through the meshing of the main gear 6. Under the drive of the motor 7, the cylinder 2 is rotated around its own axis through the meshing of the main gear 6 and the driven gear 5 to ensure the straightening effect of the upper straightening roller 12 and the lower straightening roller 13.

The pushing end of the second electric push rod 17 extends vertically downward into the interior of the portal frame 14 and is screwed and fixed to the upper surface of the lifting frame 16, thereby driving the lifting frame 16 to move vertically up and down in the area above the support roller 15 inside the portal frame 14, and ensuring that the abutment roller 18 and the support roller 15 are in tight contact with the upper and lower surfaces of the overhead wire 1 passing through the portal frame 14 respectively; like Figures 1-3 As shown, the front end of the front rotating shaft 19 extends vertically out of the front surface of the lifting frame 16 and is coaxially sleeved and fixed with the vertically and horizontally arranged measuring wheel 20, ensuring that the lifting frame 16 does not interfere with the synchronous rotation of the measuring wheel 20 with the rotating shaft 19; a first fixing plate 22 is also horizontally and longitudinally fixed on the front surface of the lifting frame 16 relative to the right side of the measuring wheel 20, and the mounting end of the meter counter 21 is fixedly connected to the lower surface of the first fixing plate 22 at the front side position through the stiffener, ensuring that the gantry frame 14 does not interfere with the vertical up and down movement of the meter counter 21 with the lifting frame 16; the measuring wheel 20 matches the detection wheel of the meter counter 21, and the detection wheel of the meter counter 21 is arranged in the rear direction and is vertically and horizontally coplanar with the measuring wheel 20. Then, through the tight contact between the detection wheel of the meter counter 21 and the measuring wheel 20, the detection wheel of the meter counter 21 rotates synchronously with the abutment roller 18 to measure the length of the overhead wire 1 passing through the gantry frame 14.

The horizontal plane of the lower surface of the upper pressure roller 31 is located below the horizontal plane of the lower end face of the third mounting frame 30. It is necessary to ensure that the upper pressure roller 31 and the lower pressure roller 27 are aligned vertically and coplanarly. After the upper pressure roller 31 descends vertically and the lower pressure roller 27 comes into close contact with the overhead conductor 1, the cooperation of the upper pressure roller 31 and the lower pressure roller 27 limits the overhead conductor 1 that passes horizontally through the gate frame 14 and ensures the stability of the cutting.

The cooperation between the sliders 37 and the corresponding slide rails 36 ensures the stability of the horizontal longitudinal movement of the two L-shaped plates 35. A grinding machine 38 is provided on the upper surface of the horizontal side of each L-shaped plate 35. The grinding ends of the two grinding machines 38 extend out of the vertical plane where the end face of the horizontal side of the corresponding L-shaped plate 35 is located. Both are semi-enclosed arcs that match the overhead conductor 1. The center of the grinding end is set in the same horizontal plane as the center of the overhead conductor 1. Then, through the synchronous movement of the two L-shaped plates 35 towards each other, the grinding ends of the two grinding machines 38 form a ring that coaxially covers the cut position of the overhead conductor 1. The grinding machine 38 can then be used to grind the cut position of the overhead conductor 1.

[0030] Among them, the extreme positions of the opposite synchronous movement of the two L-shaped plates 35 must ensure that the grinding ends of the two grinding machines 38 can form a ring to coaxially cover the cut position of the overhead wire 1; the extreme positions of the opposite synchronous movement of the two L-shaped plates 35 do not interfere with the movement of the overhead wire 1 through the portal frame 14 and the vertical up and down movement of the second mounting plate 24.

[0031] The grinding machine 38 used in this utility model is an existing cable grinding machine. It is designed with an adjustable support arm, which allows the sanding belt to adapt to the arc shape of the overhead conductor 1, so that the grinding contact surface is a semi-enclosed arc shape. Thus, the grinding operation of the overhead conductor 1 can be achieved by symmetrically setting two sets of grinding machines 38. This is the existing technology of cable grinding machines, so the specific structure and working principle of the grinding machine 38 will not be described in detail here.

[0032] The working principle of this utility model: First, the integrated device of this utility model is installed between the unwinding mechanism and the winding mechanism of the overhead conductor 1; then, one end of the overhead conductor 1 on the unwinding mechanism passes sequentially between the upper straightening roller 12 and the lower straightening roller 13, between the abutment roller 18 and the support roller 15, and between the upper pressure roller 31 and the lower pressure roller 27, and is then wound around the winding mechanism. At this time, the length of the overhead conductor 1 between the abutment roller 18 and the unwinding mechanism can be measured manually. Then, driven by the first electric push rod 9, the upper straight roller 12 and the lower straight roller 13 are respectively in contact with the upper and lower surfaces of the overhead conductor 1. Driven by the second electric push rod 17, the abutment roller 18 and the support roller 15 are respectively in contact with the upper and lower surfaces of the overhead conductor 1. Driven by the fourth electric push rod 29, the upper pressure roller 31 and the lower pressure roller 27 are respectively in contact with the upper and lower surfaces of the overhead conductor 1. At the same time, through the cooperation of the motor 7, the main gear 6, the driven gear 5 and the bearing 3, the cylinder 2 rotates around the axial direction of the overhead conductor 1 within the frame 4. At this time, the winding mechanism is started to wind up the overhead conductor 1. During the winding process, the overhead conductor 1 will drive the abutment roller 18 to rotate synchronously and drive the measuring wheel 20 to rotate synchronously. The length of the overhead conductor 1 can be measured by counting with the meter counter 21. When the required length is reached (the data from the meter counter 21 needs to take into account the previously measured length of the overhead conductor 1 between the abutment roller 18 and the unwinding mechanism, as well as the lateral length between the abutment roller 18 and the cutting assembly 25), the winding mechanism stops working. At this time, driven by the third electric push rod 23, the second mounting plate 24 descends vertically and cuts the overhead conductor 1 through the cutting assembly 25. Then, the second mounting plate 24 rises to the upper limit position. At this time, driven by the fifth electric push rod 32, the two grinding machines 38 move towards each other to the limit position and perform grinding operations on the overhead conductor 1. After grinding is completed, the two grinding machines 38 move away from each other to the limit position, and the above steps are repeated to perform the next section of overhead conductor 1 for cutting and grinding operations.

[0033] It is worth noting that the unwinding mechanism (not shown in the figure) and the winding mechanism (not shown in the figure) of the overhead conductor 1 are existing equipment used to realize the unwinding and winding actions of the overhead conductor 1. The object to be protected in this application is only the integrated cutting and grinding equipment for the overhead conductor 1. As for how the overhead conductor 1 is unwinded and wound, it does not affect the cutting and grinding working principle of this utility model. Therefore, the specific structure and working principle of the unwinding mechanism and the winding mechanism will not be described in detail here.

[0034] The beneficial effects of this utility model are: (1) This utility model realizes the integrated operation of cutting and grinding of overhead conductor 1, which not only ensures the accuracy of the cutting length of overhead conductor 1, but also saves time and effort and improves work efficiency. (2) This utility model uses the support roller 15, the abutment roller 18, the rotating shaft 19, the measuring wheel 20 and the meter counter 21 together to facilitate the length measurement of the overhead conductor 1 by the meter counter 21. In this process, the cooperation of the upper pressure roller 31 and the lower pressure roller 27 can ensure that the overhead conductor 1 is in a taut state, thereby reducing the probability of errors in the length measurement of the overhead conductor 1. This process saves time and effort and improves the measurement efficiency. (3) By using the motor 7, main gear 6, driven gear 5 and bearing 3 together, the cylinder 2 can rotate around the overhead conductor 1 in the frame 4. Then, by using the upper straightening roller 12 and the lower straightening roller 13 together, the overhead conductor 1 can be straightened before the length measurement, thus ensuring the accuracy of the length measurement of the overhead conductor 1. (4) By using the third electric push rod 23 and the fifth electric push rod 32 together, the present invention can switch between cutting and grinding operations, thereby realizing the integrated cutting and grinding operation of overhead wire 1. This process saves time and effort and improves work efficiency.

Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model.
