Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric locomotive wire support technology, specifically to a conductive wire support for a mining electric locomotive. Background Technology
[0002] Currently, long-distance transportation operations in mines mostly utilize rail-mounted electric locomotives. A conductive wire is erected above the track, and the locomotive receives power via a pantograph, driving the trailer along the track. To ensure contact between the pantograph and the conductive wire, brackets are typically used to secure the wire to a certain extent.
[0003] The complex mining environment causes the rail-mounted electric locomotive to bump and vibrate during operation, resulting in significant swaying of the conductor wire. If the conductor wire support is not installed properly or the connection is not secure enough, the conductor wire may detach from the pantograph, causing the locomotive to stop running, affecting normal production operations, or even causing a safety accident.
[0004] However, existing conductor wire brackets for mining locomotives have problems such as inconvenient installation, unsatisfactory fixing effect, and difficulty in adjusting the position after installation. Utility Model Content
[0005] To address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide an adjustable conductor support for mining locomotives, which can be quickly installed and its installation position can be easily adjusted; at the same time, when the locomotive is bumpy, it can ensure that the conductor is in the slot and in normal contact with the conductor pantograph through floating compression.
[0006] The following is the technical solution of this utility model:
[0007] An adjustable conductor wire support for a mining locomotive includes a wire fixing mechanism. The wire fixing mechanism includes an insulating porcelain insulator, with a support block fixedly connected to the lower end of the insulator. The lower end of the support block has a downward-facing wire groove. The conductor wire support also includes an elastic suspension plate. A reinforcing rib is fixedly installed on the upper side of the elastic suspension plate, and a longitudinally arranged sleeve is fixedly installed on the inner side of the reinforcing rib. A screw hole is provided on the sleeve, and a fastening bolt for fixing the sleeve to a support shaft is installed in the screw hole. A collar is fixedly installed on the outer side of the reinforcing rib. A guide rod that can slide up and down along the collar is installed inside the collar. The lower end of the guide rod is fixedly connected to the elastic suspension plate. The insulating porcelain insulator is installed below the outer end of the elastic suspension plate.
[0008] Preferably, the guide rod is threaded with an upper limit nut located above the collar and a lower limit nut located below the collar.
[0009] Preferably, the support block has a horizontally oriented side plate on each of its left and right sides; the side plate has several through slots; and a protective plate that can move up and down within the slot is installed in the slot.
[0010] More preferably, the upper end of the protective plate is connected to a horizontally oriented limiting plate; the support block has portions extending to the left and right sides, with the extended portions located directly above the side plate on the respective side.
[0011] Preferably, the upper width of the reinforcing rib is greater than the lower width, and a triangular space is left on the lower outer side of the reinforcing rib.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] First, this utility model uses a sleeve to install on the longitudinal support shaft of the roof and sidewall of an underground roadway. The installation height of the conductive wire bracket can be easily adjusted by removing and installing the fastening bolts between the sleeve and the support shaft.
[0014] Secondly, this utility model is equipped with an elastic suspension plate and a protective plate. When the locomotive bumps and causes the conductive wire to sway, the wire groove and the protective plate restrict the range of motion of the conductive wire. Furthermore, if the conductive wire moves violently, the wire fixing mechanism is stressed, causing the elastic suspension plate to float and preventing the conductive wire from coming out of the wire groove. At the same time, when the elastic suspension plate undergoes elastic deformation, it will drive the guide rod to move up and down. The collar restricts the lateral displacement of the guide rod, while the upper and lower limit nuts on the guide rod restrict the axial range of motion of the guide rod. Therefore, this utility model can ensure that the conductor is in the wire groove and in normal contact with the conductive pantograph through floating clamping. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] like Figure 1The embodiment of this utility model includes a cylindrical sleeve 1 with a radially oriented threaded hole. A fastening bolt 2 for fixing the sleeve 1 to a support shaft is installed in the threaded hole. A reinforcing rib plate 3 is also fixedly installed on the outer wall of the sleeve 1, and an elastic suspension plate 4 is fixedly connected to the lower end of the reinforcing rib plate 3. The support shaft is longitudinally arranged, and its upper end is generally fixed to the roof of the underground roadway, such as in the form of a round pipe or a steel bar. The installation height of the conductive wire bracket can be adjusted by disassembling and assembling the fastening bolt 2.
[0020] The upper width of the reinforcing rib plate 3 is greater than its lower width, leaving a triangular space on the lower outer side of the reinforcing rib plate 3. This design allows the triangular space to provide upward movement for the outer part of the elastic suspension plate 4 (i.e., the part not connected to the lower end of the reinforcing rib plate 3) when it floats up and down under force. A collar 3-1 is fixedly installed on the outer side of the reinforcing rib plate 3. A guide rod 6, which can slide up and down along the inner wall of the collar 3-1 (i.e., the collar 3-1 can move axially along the guide rod 6), is installed inside the collar 3-1. The lower end of the guide rod 6 is fixedly connected to the elastic suspension plate 4, and an upper limit nut 6-1 located above the collar 3-1 and a lower limit nut 6-2 located below the collar 3-1 are threaded onto the guide rod 6. When the elastic suspension plate 4 undergoes elastic deformation and floats up and down, the collar 3-1 limits the range of motion of the elastic suspension plate 4 through the limiting bolts.
[0021] The outer end of the elastic suspension plate 4 is provided with a through hole running vertically. This embodiment also includes... Figure 2 The wire fixing mechanism 5 is shown. The wire fixing mechanism 5 includes an insulating porcelain bottle 5-1, and a screw 5-7 is provided at the upper end of the insulating porcelain bottle 5-1. The screw 5-7 passes through the through hole and is connected to a suspension nut at its upper end. The insulating porcelain bottle 5-1 is suspended below the elastic suspension plate 4 by the screw 5-7 and the suspension nut.
[0022] The lower end of the insulating porcelain bottle 5-1 is fixedly connected to a support block 5-2. The lower end of the support block 5-2 has a downward-facing groove 5-3 with an arc-shaped cross-section.
[0023] Furthermore, each of the left and right sides of the support block 5-2 is provided with a horizontally oriented side plate 5-4 (the inner edges of the two side plates 5-4 are fixed to the left and right sides of the support block 5-2 respectively). Several through slots are formed on the side plates 5-4. A protective plate 5-6, capable of moving up and down within the slot, is installed in each slot. The lower part of the protective plate 5-6 is generally designed to be arc-shaped to minimize resistance when the pantograph of the electric locomotive passes over it.
[0024] Furthermore, to longitudinally limit the protective plate 5-6, a horizontally oriented limiting plate 5-5 is connected to the upper end of the protective plate 5-6. The outer contour dimension of the limiting plate 5-5 is larger than the corresponding slot dimension, preventing the protective plate 5-6 from falling downward from its slot. On the other hand, the support block 5-2 has portions extending to the left and right sides, which are located directly above the side plate 5-4 on their respective sides to prevent the protective plate 5-6 from falling upward from its slot.
[0025] The specific assembly and usage of this utility model will be described in detail below.
[0026] First, place sleeve 1 onto the support shaft, adjust it to a suitable height and angle, and then tighten the fastening bolt 2 to fix the position of sleeve 1.
[0027] The second step is to pass the screw 5-7 of the wire fixing mechanism 5 through the through hole on the elastic suspension plate 4, finely adjust the angle of the wire fixing mechanism 5, and then tighten the suspension nut on the screw 5-7 to complete the installation of the wire fixing mechanism 5.
[0028] When the locomotive vibrates, causing the conductive wire to sway, the wire groove 5-3 and the protective plate 5-6 restrict the range of motion of the conductive wire. Furthermore, if the conductive wire moves violently, the wire fixing mechanism 5 is subjected to force, causing the elastic suspension plate 4 to float, preventing the conductive wire from coming off the wire groove 5-3. Simultaneously, when the elastic suspension plate 4 undergoes elastic deformation, it will cause the guide rod 6 to move vertically. The collar 3-1 restricts the lateral displacement of the guide rod 6, while the upper limit nut 6-1 and lower limit nut 6-2 on the guide rod 6 restrict the axial range of motion of the guide rod 6.
[0029] When the pantograph passes by, it comes into contact with the protective plate 5-6. The lower part of the protective plate 5-6 is arc-shaped, which can reduce the resistance when the pantograph passes by. At the same time, the protective plate 5-6 moves upward under the force, which facilitates the passage of the pantograph.
