Cable fixed wheel device for electric shovel
Technical Field
The invention relates to the technical field of electric shovels, in particular to a cable fixing wheel device for an electric shovel.
Background
An electric shovel is also called a rope shovel and a steel cable shovel, namely a mechanical electric excavator is a single bucket excavator which transmits power by using transmission parts such as gears, chains, steel cable pulley blocks and the like, and the electric shovel has been produced for centuries.
However, there are some disadvantages in the conventional using process, such as:
because the cable rubs with ground when the electric shovel moves, can cause the cable to appear the electric leakage phenomenon of skinning, and cable operating distance overlength can lead to the electric shovel cable joint to drop from the distribution board, causes the problem of electric shock accident and equipment accident to this problem is solved with the cable tight pulley device to provide an electric shovel.
Disclosure of Invention
The invention aims to provide a cable fixing wheel device for an electric shovel, which solves the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: comprises a mounting plate; the fixed rod is fixedly welded on the surface of the top of the mounting plate; the top of the fixed rod is rotatably connected with a pair wheel; the surface of the fixed rod is positioned between the mounting plate and the pair wheel, and the return spring is wound on the surface of the fixed rod; the clamping mechanism comprises a through hole, a first spring and a clamping plate, the through hole is formed in the surface of the pair of wheels and located on one side of the top of the pair of wheels, the first spring is fixedly welded to two sides of the through hole, and the clamping plate is fixedly welded to one end, far away from the inner wall of the through hole, of the first spring; and the grooves are formed in the inner parts of the pair wheels and positioned at the tops of the through holes.
The clamping plate is of an arc-shaped structure, and one side, far away from the first spring, of the clamping plate is connected with an anti-slip pad in an adhesive mode.
Wherein, the surface bonding of the pair wheel is connected with the rubber pad.
The fixed rod is located on two sides of the inner portion of the pair wheel and is connected with a rotating ball in a rotating mode, and the rotating ball is connected with the inner portion of the pair wheel in a sliding mode.
Wherein, the inside both sides of mounting panel have all been seted up the mounting hole.
Compared with the prior art, the invention has the beneficial effects that:
the clamping plates are pushed to move towards the directions far away from each other, the first spring is extruded, the cable moves downwards through the grooves until the cable is moved into the through hole and positioned between the clamping plates, then the clamping plates are loosened, under the restoring elastic action of the first spring, the first spring pushes the clamping plates to move towards the directions close to each other, the cable can be clamped and fixed, then the cable is wound on the surface of the coupling wheel, when the electric shovel is far away in running distance, the coupling wheel can be driven to rotate, the cable can be lengthened, meanwhile, under the action of the clamping mechanism, the cable can be limited and fixed, the problem that the cable connector is pulled out of the switchboard can be avoided, the problem that the connector is dropped is effectively prevented, when the electric shovel is near in running distance, the return spring drives the coupling wheel to rotate reversely under the action of the return spring, and the cable can be wound on the surface of the coupling wheel, the problem that the cable is damaged due to friction with the ground is avoided.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: comprises a mounting plate 1; the fixed rod 3 is fixedly welded on the top surface of the mounting plate 1; the top of the fixed rod 3 is rotatably connected with a pair wheel 4; the surface of the fixed rod 3 is positioned between the mounting plate 1 and the pair wheel 4, the return spring 2 is wound on the surface of the fixed rod, one end of the return spring 2 is fixedly mounted with the pair wheel 4, and the other end of the return spring 2 is fixedly mounted with the mounting plate 1; the clamping mechanism 7 comprises a through hole 71, a first spring 72 and a clamping plate 73, the through hole 71 is formed in the surface of the pair wheel 4 and located on one side of the top of the surface, the first spring 72 is fixedly welded to two sides of the through hole 71, and the clamping plate 73 is fixedly welded to one end, far away from the inner wall of the through hole 71, of the first spring 72; and a groove 6 is formed in the inner part of the pair of wheels 4 and positioned at the top of the through hole 71, and the groove 6 is formed.
The clamping plate 73 is of an arc-shaped structure, and a non-slip pad is bonded to one side of the clamping plate 73, which is far away from the first spring 72, so that the friction force between the clamping plate 73 and the cable is increased.
Wherein, the surface bonding of wheel 4 is connected with rubber pad 5, avoids the problem that the cable surface takes place the damage.
Wherein, the dead lever 3 is located the inside both sides of wheel 4 and all rotates and is connected with the turning ball, the inside sliding connection of turning ball and wheel 4 reduces and rotates and makes frictional force.
Wherein, the inside both sides of mounting panel 1 have all been seted up the mounting hole, the installation of being convenient for.
The working principle is as follows: when the cable connector is used, a safe and firm place is selected at the working place of the electric shovel to install and fix the mounting plate 1, the clamping plates 73 are pushed to move towards the direction away from each other, the first springs 72 are extruded, the cables are inserted into the inner part of the pair of wheels 4 through the grooves 6 and then move downwards until the cables are moved into the through holes 71 and positioned between the clamping plates 73, then the clamping plates 73 are loosened, under the restoring elastic action of the first springs 72, the first springs 72 push the clamping plates 73 to move towards the direction close to each other, the cables can be clamped and fixed, then the cables are wound on the surface of the pair of wheels 4, when the electric shovel is far away from the working distance, the pair of wheels 4 can be driven to rotate, the cables are lengthened, meanwhile, under the action of the clamping mechanism 7, the cables can be limited and fixed, the problem that the cable connectors are pulled out from the switchboard can be avoided, and the problem that the connectors fall off, when the electric shovel driving distance is nearer, under the effect of return spring 2 for return spring 2 drives the counter-rotation of coupling 4, can avoid cable and ground friction, produces damaged problem with the cable rolling on the surface of coupling 4.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
