Description

Technical Field

[0001] The invention relates to the technical field of train tractors, in particular to an energy supply mechanism and a fixed-distance train tractor. Background Art

[0002] After the railway coal trains of some power plants, steel plants, cement plants and other enterprises enter the factory, they need to be transported again in the factory during the loading and unloading process. The transportation method generally requires the heavy-loaded freight trains to be towed over a short distance and a fixed distance.

[0003] At present, there are several ways to shun heavy trains: standard locomotive, rack-type shunting locomotive, tractor tractor, and diesel tractor:

[0004] 1. Standard locomotives: Currently, there are mainly two types of locomotives: diesel locomotives and electric locomotives. Standard locomotives are complex in structure, expensive, and require drivers with professional train driving qualifications to operate. As a normal working condition, the investment of enterprises is too large; and because of the train shunting operations within the enterprise, the frequency of use is low. The cost-effectiveness of using standard locomotives is too low.

[0005] 2. Rack-type tractor: This type of tractor uses a ground rack as the reverse driving force to push the train. This traction method requires the layout of a large ground rack, so the cost is relatively high. This traction method is mainly used in the loading and unloading operation area of ​​the tipping machine with precise positioning.

[0006] 3. Iron ox towing car: This traction method is driven by a motor reducer and uses a long-distance wire rope for traction operations. The equipment layout route is long, the iron ox drive room occupies a large area, and the investment is high. Because several thousand meters of wire rope need to be arranged as traction rope, hundreds of pulley sets are required for guiding the wire rope, the equipment defect rate is high, and the equipment operation is unstable.

[0007] 4. Diesel locomotive traction: This type of equipment is generally borrowed from a loader or forklift

[0008] It is an improved chassis with the advantages of dual use for road and rail and easy mobility. However, for enterprise use, diesel locomotives need to be refueled regularly and have disadvantages such as complex structure and high maintenance.

[0009] In addition, there are small electric traction vehicles used for maintenance as train traction vehicles, which can only tow one or two train carriages and cannot meet the needs of towing heavy-load trains. Summary of the invention

[0020] Wherein, the cleaning ring is sleeved on the outside of the cable, and the cleaning ring is located at the bending center of the cable, and the connecting rod is connected to the protective shell through a torsion spring.

[0021] The present invention also provides a fixed-distance train tractor.

[0022] In order to solve the above technical problems, the present invention also provides the following technical solutions: a fixed distance train tractor, based on the energy supply mechanism, further includes a bearing mechanism, a connecting mechanism, a driving mechanism and an operating room;

[0023] Wherein, the bearing mechanism comprises a main body component, a brake arranged at the bottom end of the main body component, and a traction hook arranged at the front end of the main body component;

[0024] The main body component is used to carry and install the operating room, and the connecting mechanism is used to connect the carrying mechanism and the driving mechanism.

[0025] As a preferred solution of the fixed-distance train tractor of the present invention, the main body component includes a chassis, a guardrail arranged on the top of the chassis, and a climbing ladder adapted to be installed on the outside of the chassis.

[0026] As a preferred solution of the fixed distance train tractor of the present invention, the connection mechanism comprises an upper connecting block adapted to be installed at the bottom end of the chassis, a lower connecting block adapted to be installed with the upper connecting block, and a bearing box arranged between the upper connecting block and the lower connecting block, the bottom end of the upper connecting block is slidably connected with an inner rod, and the outer side of the inner rod is sleeved with a shock absorbing spring;

[0033] 2. During the operation of the cable tractor, the rubber roller rotates during the cable unwinding and rewinding process, affecting the rotation of the turntable. When unwinding, the tooth block will not push the push rod due to the bevel and the reset spring, keeping the cleaning ring stable and reducing the cable resistance. When rewinding, the tooth block pushes the push rod, causing the connecting rod and the cleaning ring to swing. The cleaning ring removes the soot on the cable surface by scraping and shaking, ensuring the cleanliness of the cable after rewinding. The cleaning ring is located at the center of the cable bend, providing support and effectively shaking off the soot. Whether it is located at the upper or lower end of the bend, it is impossible to achieve efficient cleaning of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0047] Example 1

[0048] Reference Figure 1 , Figure 4 , which is the first embodiment of the present invention, and provides an energy supply mechanism, including a winding component 101 and a combing component 102, wherein the combing components 102 are arranged in two groups, and the two groups of combing components 102 are symmetrically designed;

[0049] The winding component 101 is used for winding and releasing the cable 1 , and the combing component 102 is used for guiding and cleaning the cable 1 .

[0050] Specifically, the winding component 101 includes a mounting frame 101 a and a hysteresis cable reel 101 b adapted to be mounted inside the mounting frame 101 a , and the hysteresis cable reel 101 b is used for winding and releasing the cable 1 .

[0051] The hysteresis cable reel 101b can realize automatic retraction and release of the cable 1, ensuring that the cable 1 can stably supply energy to the variable speed drive 401a, making it easy to drive the tractor to move.

[0052] With the assistance of the combing component 102, the cable 1 can be guided during the process of being retracted and released, and the outer surface of the cable 1 can be cleaned when it is reeled.

[0053] In summary, the hysteresis cable reel 101b automatically retracts and releases the cable 1, stably supplies power to the variable speed drive 401a, and drives the tractor to move. The combing component 102 assists in cable guidance and cleaning.

[0054] Example 2

[0055] Reference Figure 1 , Figures 4 to 8 , which is a second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a combing component 102, including a protective shell 102a, a notch 102b opened at the bottom end of the protective shell 102a, and a rubber roller 102c rotatably connected to the inside of the protective shell 102a;

[0056] The rubber rollers 102c are arranged in four groups, and every two groups of rubber rollers 102c cooperate with the retraction and extension of the auxiliary cable 1. The outer sides of the two groups of rubber rollers 102c are provided with one-way components 102d, and the interior of the protective shell 102a is adapted to be installed with a cleaning component 102e.

[0057] Specifically, the one-way component 102d includes a rotating disk 102d-1 fixedly connected to the outside of the rubber roller 102c, a return spring 102d-2 fixedly connected to the inside of the rotating disk 102d-1, and a tooth block 102d-3 fixedly connected to one end of the return spring 102d-2;

[0058] Among them, one end of the tooth block 102d-3 is set to be an oblique angle.

[0059] Furthermore, the cleaning assembly 102e includes a connecting rod 102e-1 rotatably connected to the inside of the protective shell 102a, two sets of push rods 102e-2 fixedly connected to the outside of the connecting rod 102e-1, and a short rod 102e-3 fixedly connected to the outside of the connecting rod 102e-1, and one end of the short rod 102e-3 is fixedly connected to a cleaning ring 102e-4;

[0060] The cleaning ring 102e-4 is sleeved on the outside of the cable 1, and the cleaning ring 102e-4 is located at the bending center of the cable 1, and the connecting rod 102e-1 is connected to the protective shell 102a through a torsion spring.

[0061] When the cable 1 is in the process of unwinding, the four groups of rubber rollers 102c rotate toward the cable 1 under the movement of the cable 1, and the turntable 102d-1 outside the two groups of rubber rollers 102c also rotates accordingly, and the tooth block 102d-3 is at an angle on one side, and with the design of the return spring 102d-2, the rotating tooth block 102d-3 at this time shrinks toward the inside of the turntable 102d-1 when squeezing the push rod 102e-2 through the angle, and cannot drive the push rod 102e-2 to move. In this way, the stability of the cleaning ring 102e-4 can be guaranteed.

[0062] When the cable 1 is in the process of winding, the four groups of rubber rollers 102c rotate in the opposite direction under the movement of the cable 1, and the turntables 102d-1 outside the two groups of rubber rollers 102c also rotate accordingly. However, due to the change in the direction of rotation, the end of the tooth block 102d-3 without an angle squeezes the push rod 102e-2, and the push rod 102e-2 drives the connecting rod 102e-1 to rotate under the action of the squeezing force, and the torsion spring inside the connecting rod 102e-1 is deformed, and finally drives the cleaning ring 102e-4 at one end of the short rod 102e-3 to swing. After the turntable 102d-1 drives the tooth block 102d-3 to separate from the push rod 102e-2, the torsion spring drives the connecting rod 102e-1 and the outer connecting rod 102e-1 and the cleaning ring 102e-4 to reset. The continuous rotation of the turntable 102d-1 will cause the tooth block 102d-3 to squeeze and separate the push rod 102e-2, ultimately achieving the reciprocating swing of the cleaning ring 102e-4 outside the connecting rod 102e-1.

[0063] Since the tractor is in the working environment of traction coal car, a lot of coal dust will be attached to the ground. When the cable 1 is in the process of releasing the cable, the cleaning ring 102e-4 remains stationary, which can reduce the resistance of the cable 1 during release and facilitate the release of the cable 1; and when the cable 1 is in the process of reeling in the cable, the cleaning ring 102e-4 can scrape the coal dust attached to the surface of the cable 1, and the shaking of the cleaning ring 102e-4 can shake off the scraped coal dust, ensuring the cleanliness of the outer surface of the cable 1 after reeling in, so as to facilitate long-term storage.

[0064] Since the cleaning ring 102e-4 is located at the bend center of the cable 1, it can not only provide strong support for the cable 1 during the guiding process, but also effectively shake off the scraped coal dust from the surface of the cable 1 during the shaking process. If the cleaning ring 102e-4 is located at the upper end of the bend, the shaken coal dust falls along the surface of the cable 1, and if the cleaning ring 102e-4 is located at the lower end of the bend, the coal dust on the upper side of the cable 1 is difficult to shake off.

[0065] In summary, during the operation of the cable tractor, the rubber roller 102c rotates during the unwinding and rewinding of the cable 1, affecting the rotation of the turntable 102d-1. When unwinding, the tooth block 102d-3 will not push the push rod 102e-2 due to the bevel and the return spring 102d-2, keeping the cleaning ring 102e-4 stable and reducing the cable resistance. When rewinding, the tooth block 102d-3 pushes the push rod 102e-2, causing the connecting rod 102e-1 and the cleaning ring 102e-4 to swing. The cleaning ring removes the coal ash on the surface of the cable 1 by scraping and shaking, ensuring the cleanliness of the cable 1 after rewinding. The cleaning ring is located at the cable bend center, providing support and effectively shaking off the coal ash. Whether it is located at the upper or lower end of the bend, it is impossible to achieve efficient cleaning of the cable 1.

Different from the previous embodiment, this embodiment provides a fixed-distance train tractor, which, based on the energy supply mechanism, also includes a bearing mechanism 200, a connecting mechanism 300, a driving mechanism 400 and an operating room 500;

[0068] The bearing mechanism 200 includes a main body 201, a brake 202 disposed at the bottom end of the main body 201, and a traction hook 203 disposed at the front end of the main body 201;

[0069] The main body component 201 is used to carry and install the operating room 500 , and the connecting mechanism 300 is used to connect the carrying mechanism 200 and the driving mechanism 400 .

The traction hook 203 is used to connect the coal car, and the brake 202 is used to brake the tractor.

[0072] Example 4

[0073] Reference Figure 1 , Figure 2 , which is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment provides a connecting mechanism 300, including an upper connecting block 301 adapted to be installed at the bottom end of the chassis 201a, a lower connecting block 302 adapted to be installed with the upper connecting block 301, and a bearing box 303 arranged between the upper connecting block 301 and the lower connecting block 302. The bottom end of the upper connecting block 301 is slidably connected with an inner rod 304, and the outer side of the inner rod 304 is sleeved with a shock absorbing spring 305;

[0074] The bottom end of the inner rod 304 is connected to the lower connecting block 302 , one end of the shock absorbing spring 305 is connected to the upper connecting block 301 , and the other end of the shock absorbing spring 305 is connected to the lower connecting block 302 .

[0075] The design of the connecting mechanism 300 can ensure that even if the tractor shakes during movement, the special structural facilities of the shock-absorbing spring 305, the upper connecting block 301, the lower connecting block 302 and the bearing box 303 can be used to reduce shock, thereby ensuring the stable operation of the vehicle.

[0076] Example 5

[0077] Reference Figure 1 to Figure 3 , which is the fifth embodiment of the present invention. Different from the previous embodiment, this embodiment provides a driving mechanism 400, including a power component 401 and a moving component 402, and the power component 401 provides power to the moving component 402;

[0078] The power assembly 401 includes a variable speed drive 401a adapted to be installed at the bottom of the chassis 201a, a small sprocket 401b fixedly connected to the output end of the variable speed drive 401a, and a chain 401c meshed with the outside of the small sprocket 401b.
