Description

Technical Field

[0001] The invention relates to the field of overhead guy wires, in particular to a connecting and fixing device for an electric locomotive overhead guy wire. Background Art

[0002] The operation of electric locomotives requires the pre-arrangement of the transmission power grid with overhead wires. Traditional overhead wires are galvanized iron wires. Since the overhead wires need to be laid underground, the underground environment is humid and the overhead wires are easily corroded and broken. Therefore, they need to be replaced frequently, which is labor-intensive. Even if the underground environment is good and the overhead wires are in good condition, it is difficult to remove the wires and reuse them in the same mining area, which increases costs. Summary of the Invention

[0003] The purpose of the present invention is to provide a device for connecting and fixing an overhead cable of an electric locomotive to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The electric locomotive overhead pull wire connection and fixing device includes an upper fixing plate, a lower fixing plate and a fixing rod. The upper fixing plate is located above the lower fixing plate and cooperates with the lower fixing plate. The bottom end of the fixing rod passes through the upper fixing plate and is fixedly connected to the top surface of the lower fixing plate. The fixing rod is provided with a reset mechanism at the position above the upper fixing plate. The top surface of the upper fixing plate is symmetrically provided with a locking mechanism, and the locking mechanism cooperates with the mounting plate assembly at the top end of the fixing rod.

[0006] Furthermore, the top surface of the upper fixing plate and the bottom surface of the lower fixing plate are symmetrically provided with reinforcement plates, and a sliding sleeve is embedded at the joint between the upper fixing plate and the fixing rod.

[0007] Furthermore, the reset mechanism includes a reset spring, which is sleeved on the fixed rod, and the bottom end of the reset spring is fixedly connected to the top end of the sliding sleeve, and the top end of the reset spring is welded to the bottom surface of the limit plate welded on the fixed rod.

[0008] Furthermore, when the return spring is not acted upon by an external force, the upper fixing plate and the lower fixing plate are separated.

[0009] Furthermore, the locking mechanism includes a support rod with an inverted U-shaped structure, the two bottom ends of the support rod are movably connected to the corresponding reinforcing plates, and a rotating cylinder is sleeved on the crossbar part of the upper part of the support rod.

[0010] Furthermore, the mounting plate assembly includes a mounting fixing plate, and a support plate is symmetrically provided on the bottom surface of the mounting fixing plate.

[0011] Furthermore, the support plate corresponds to the position of the rotating drum, and the end of the support plate is provided with a slot that cooperates with the rotating drum.

[0012] Furthermore, an insulator is provided between the reset mechanism and the mounting plate assembly.

[0013] Furthermore, wire fixing grooves are symmetrically provided between the upper fixing plate and the lower fixing plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, when fixing the overhead pull wire, the locking mechanism is not locked and fixed. At this time, the upper fixed plate is separated from the lower fixed plate under the action of the reset spring, which facilitates the placement of the overhead pull wire. After the overhead pull wire is placed, the support rod is rotated and the rotating drum is contacted and squeezed with the bottom surface of the installation fixing plate, so that the upper fixed plate gradually approaches the lower fixed plate until the upper and lower fixed plates are fitted together. At this time, the support rod is in a vertical state, and the rotating drum is engaged with the slot to limit the position of the support rod. The reset spring is also in a pulled state to keep the support rod stable and fixed.

[0016] If you need to remove the overhead guy wire, you only need to separate the support rod from the installation fixing plate. Under the action of the reset spring, the upper fixing plate and the lower fixing plate will separate, and the overhead guy wire can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , the present invention provides a technical solution:

[0023] The electric locomotive overhead pull wire connection and fixing device includes an upper fixing plate 1, a lower fixing plate 2 and a fixing rod 3. The upper fixing plate 1 is located above the lower fixing plate 2 and cooperates with the lower fixing plate 2. The bottom end of the fixing rod 3 passes through the upper fixing plate 1 and is fixedly connected to the top surface of the lower fixing plate 2. The fixing rod 3 is provided with a reset mechanism 4 at the top of the upper fixing plate 1. The top surface of the upper fixing plate 1 is symmetrically provided with a locking mechanism 5, which cooperates with the mounting plate assembly 6 at the top of the fixing rod 3.

[0024] This technical solution changes the traditional fixing method, making the installation, repair and disassembly of the overhead wire more convenient.

[0025] Among them, the top surface of the upper fixed plate 1 and the bottom surface of the lower fixed plate 2 are symmetrically provided with reinforcement plates 7, which are used to increase the structural strength of the upper fixed plate 1 and the lower fixed plate 2. A sliding sleeve 8 is embedded at the joint between the upper fixed plate 1 and the fixed rod 3. The sliding sleeve 8 makes the sliding between the upper fixed plate 1 and the fixed rod 3 more convenient.

[0026] The reset mechanism 4 preferably has the following structure: it includes a reset spring 41, the reset spring 41 is sleeved on the fixed rod 3, and the bottom end of the reset spring 41 is fixedly connected to the top end of the sliding sleeve 8, the top end of the reset spring 41 is welded to the bottom surface of the limit plate 42 welded on the fixed rod 3, the surface of the reset spring 41 is treated with anti-corrosion, and when the reset spring 41 is not subjected to external force, under the action of tension, the upper fixed plate 1 and the lower fixed plate 2 are separated (at this time the locking mechanism 5 is locked).

[0027] The locking mechanism 5 preferably has the following structure: a support rod 51 having an inverted U-shaped structure, the two bottom ends of the support rod 51 being movably connected to the corresponding reinforcing plates 7, a rotating cylinder 52 being sleeved on the cross bar portion on the upper part of the support rod 51, the support rod 51 being rotatable, and the rotating cylinder 52 and the support rod 51 being rotatable relative to each other.

[0028] The mounting plate assembly 6 preferably has the following structure: it includes a mounting plate 61, and a support plate 62 is symmetrically provided on the bottom surface of the mounting plate 61. The support plate 62 corresponds to the position of the rotating drum 52, and the end of the support plate 62 is provided with a slot 63 that cooperates with the rotating drum 52.

[0029] An insulator 9 is provided between the reset mechanism 4 and the mounting plate assembly 6 .

[0030] Wire fixing grooves 10 are symmetrically provided between the upper fixing plate 1 and the lower fixing plate 2 .

[0031] When fixing the overhead pull wire, the locking mechanism 5 is not locked and fixed. At this time, the upper fixed plate 1 is separated from the lower fixed plate 2 under the action of the reset spring 41, which facilitates the placement of the overhead pull wire. After the overhead pull wire is placed, the support rod 51 is rotated and the rotating cylinder 52 is contacted and squeezed with the bottom surface of the upper fixed plate 1, so that the upper fixed plate 1 gradually approaches the lower fixed plate 2 until the upper fixed plate 1 and the lower fixed plate 2 are fitted together. At this time, the support rod 51 is in a vertical state, and the rotating cylinder 52 is engaged with the slot 63 to limit the position of the support rod 51. The reset spring 41 is also in a pulled state to keep the support rod 51 stable and fixed.

[0032] If the overhead guy wire needs to be removed, the support rod 51 only needs to be separated from the mounting plate 61. Under the action of the return spring 41, the upper fixing plate 1 and the lower fixing plate 2 are separated, and the overhead guy wire can be taken out.

[0033] Among them, when the support rod 51 is locked in place, it can also be tilted at a small angle (such as 0-5 degrees) toward the direction of the fixed rod 3, so that the support rod 51 is not easily disengaged under the pulling force of the reset spring 41, and the locking state remains stable.

[0034] Among them, the overhead guy wire is preferably made of stainless steel wire rope.
