Description

Improved structure of split heavy vehicle trolley arm

Technical Field

The utility model relates to a shallow arm transformation technical field specifically indicates a split type heavy duty car shallow arm improves structure.

Background

When the railway open wagon is used for dumping goods, a heavy wagon is firstly pushed into the wagon dumper, then the open wagon is overturned for a certain angle to dump the goods, and then the unloaded empty wagon is pushed out by the empty wagon pushing device. The existing empty cart device is provided with a walking wheel on a cart body, and the walking wheel rolls in a track to enable the cart body to run. A trolley arm is arranged on the trolley body, and a roller is arranged at one end of the trolley arm. The two ends of the vehicle body are connected with a steel wire rope which is connected with a hoisting traction part of the vehicle body. When the winch traction part works to pull the steel wire rope, the car body moves along the rail, so that the end of the cart arm is just propped against the axle of the truck, and the truck is pushed out of the car dumper. At present, the empty car pusher device of the tippler in the sintering operation area has the following problems: the pusher cart drives the train wagon to move forwards by pushing a cart arm on a wheel axle of the train wagon, and in the process of pushing the train wagon, the cart arm often damages a wind pipe and a U-shaped pipe on the wheel axle of the train wagon, so that the train wagon cannot normally exhaust and inflate and safety parts of the train wagon are damaged; secondly, the trolley arm of the trolley pusher is easy to bend and deform, and therefore needs to be replaced in time; the spring arranged on the cart arm is easy to fatigue failure and even break due to overlarge impact force, and generally needs to be replaced in time after being used for about two months. The damage of the car pusher causes the car dumper to be forced to stop producing, which brings great pressure to production, and the damage of the wagon increases the promotion of transportation cost. In addition, the service life of the car pusher is short, and the car pusher can be normally used only by frequent maintenance. After retrieval: the document of finding an empty car pushing device of a tipper relates to a pushing device for pushing out an empty car after dumping goods on a railway open car. The automatic lifting device comprises a cart track, a cart body travelling wheel moving along the track, and a driving steel wire connected with the two ends of the cart body and connected with a winch power mechanism. The defects of complicated structure, multiple equipment fault points and low working efficiency exist. The existing cart device is characterized in that two guide rails are arranged in a railway track, a cart body with wheels is arranged on the guide rails, a cart arm is arranged on the cart body, a cart skin moves along the track under the driving of power or traction, the cart device is matched with a car dumper to realize the operation of car conveying, car moving and cart, and the use and the control are more convenient. However, in the trolley device, the axles at the lower part of the trolley leather move the trolley leather, which can cause the dislocation of the brake, the damping device and the like, and can generate potential safety hazards on the bearing and the operation of the trolley leather. The railway department has been in formal prosecution in 96 years because the axle pushing mode has great harm to the safe operation of the train, and the car pusher using fixed parts such as direct axle pushing and the like is forbidden. Meanwhile, the cart part of the car pusher is only the wheel tread of the wagon or the coupler part of the wagon. The' unloading shunting machine for bulk goods wagon disclosed in CN2033794U is characterized in that guide rails are laid on the outer sides of two rails of a train, the shunting machine runs on the guide rails, and a movable trolley arm is arranged on the shunting machine and can put down a trolley corresponding to a wagon coupler. The cart mode is simple and intuitive in design, but the cart arm is long in cantilever and large in bending moment, so that the shunting machine is huge in structure, not reasonable in stress, large in occupied space area and large in platform area outside the rail, and railway operation is not facilitated. Chinese patent publication No.: CN2303757Y, announcement date: 13 days 1 month 1999, the utility model entitled "wagon pusher" proposes that a guide rail is arranged at the inner side of a railway track, a wheel type trolley is placed on the guide rail, a pushing arm is arranged on the wheel type trolley, and the trolley is pushed by a wagon wheel on the corresponding railway track. This scheme shallow effect is better. However, in order to reduce the length of the trolley arm, the trolley body in the technical scheme is wider, and the used guide rail mostly adopts a heavy cow rail, so that the breakpoint on the rail is increased, and the trolley receiving distance of the heavy cow is easily influenced; the linear reciprocating mechanism for resetting the cart arm is large in size and complex in structure, the stress direction of the linear reciprocating mechanism is also changed in a reciprocating mode when the cart arm is opened and closed, and the stress of the mechanism is not reasonable enough; the strength and stability of the arm of the trolley are still to be improved, and the arm is not convenient to fold. Industrial and mining enterprises generally adopt standard-rail or narrow-rail railways to transport substances such as coal, ores, building materials and the like. When a train or a mine car runs for a long distance, the train or the mine car is generally pulled by a locomotive, and when the train or the mine car is dispatched in a loading station, a unloading yard or a marshalling station yard, the train or the mine car can be moved in several ways of the locomotive, a dispatching winch, a stepless rope type car pusher or a manual cart (only for a small number of narrow-gauge mine cars). The locomotive is shunting, the locomotive is often pulled from the front end of the train to the rear end of the train to jack the train in the shunting process, the operation is back and forth, the operation procedure is complex, the time is long, the efficiency is low, the energy consumption is large, an auxiliary return line is needed, the yard is complex, and the occupied area is large; a dispatching winch is generally characterized in that a single-drum winding type slow-motion winch is fixed at one end of a yard, a steel wire rope is manually pulled to the tail end of a train, the steel wire rope is fixed on a tail carriage, then the winch is started, and the train is pulled. The labor intensity of workers is high, the working environment is poor, the efficiency is low, and the carriage is easy to damage by pulling; the stepless rope type car pusher is also called a shunting winch, the traction steel wire rope is arranged in the middle of the track and is connected with a car pusher in the middle of the track, and the car pusher moves back and forth along the track, so that the operation of pushing and shunting is realized. The shunting mode has the advantages of high mechanization and automation degrees, simple operation and high efficiency. In summary, among the shunting modes, the stepless rope type car pusher has the advantages of high automation degree, simple operation, high efficiency and the like, but the existing rope type car pusher can only run on a linear track and cannot pass through a curve. In practical application, the line layout of the parking lot is restricted by various external factors. If the parking lot needs to be arranged according to the terrain in mountainous and hilly areas so as to reduce the volume of earth and stone as much as possible, the track line needs to be arranged in the coal mine underground parking lot according to geological conditions so as to reduce the amount of roadway development projects as much as possible, the track line is often provided with a curve, and vehicles need to run in the curve, so that the conventional rope type car pusher cannot be suitable in the situation, and the locomotive is generally adopted for shunting.

The car pusher is mainly used for transporting vehicles such as mine ports or shaft bottom yard dispatching mine cars, flat cars, material trucks and the like and auxiliary materials thereof. It can also be used for dispatching and transporting the transportation yards of metallurgical mine yards, non-metal mine yards and engineering building yards (such as tunnels). The device has the characteristics of high production efficiency, simple operation, convenient use, safety, reliability and the like. According to the structural form and the energy used, the car pusher mainly used at present is three types of mechanical car pusher, pneumatic car pusher and hydraulic car pusher, the traditional car pusher is installed between two tracks on which a mine car runs, once the car pusher equipment of the form is in failure, the maintenance is relatively difficult, the equipment can be maintained only by stopping production, the installation structure is relatively complex, the car pusher is only suitable for the application of heavy or heavy-duty mine cars, and the maintenance cost of the car pusher of the traditional form is relatively high for the transportation of light mine cars. With the large-scale application of chain conveyors in the automobile manufacturing industry, the role of car pushers as their auxiliary components plays an indispensable role in beat satisfaction. The reliability, safety and economy of the car pusher, convenience in maintenance and the like are more and more urgent. The driving device of the existing car pusher adopts a rodless cylinder, has short stroke, is influenced by the stroke in the using process and increasingly shows the influence on the improvement of the beat. The existing structure of the car pusher on the upper yard of the underground auxiliary transport hoister of each coal mine comprises a hydraulic push rod type car pusher and a car pusher matched with a rope type motor reduction box, and the car pusher adopting the hydraulic push rod has the advantages of more equipment investment, large fund investment, large power consumption and high operation cost; the car pusher adopting the common rope type motor reduction box matched type has the advantages of needing to be driven into an assembly chamber, having high construction cost, easy damage and large maintenance amount, and not meeting the requirements of energy conservation and emission reduction. The dumper system is a heavy car pusher, which is an important equipment component for loading and unloading coal cars in a thermal power plant, the running reliability of the dumper system directly influences the key of smooth loading and unloading of the coal cars, and the loading and unloading time of the coal cars is too long, so that the state iron carries out vehicle backlog overtime economic assessment according to regulations and regulations, and certain economic loss can be caused to companies. After the heavy car pusher is installed and put into use and runs for a short time, the problem that the track of the heavy car pusher falls frequently occurs, through careful observation and analysis, the problem that the design and the use of a running wheel rotating bearing of the heavy car pusher are unreasonable is found, the original designed running wheel uses a self-aligning bearing, and during running and walking, the shaking angle is large, so that the problem that the track falls due to deviation of a track is caused. Aiming at the problem, the bearing of the traveling wheel of the car pusher is improved, the model is redesigned and selected, a deep groove ball bearing is selected, a new wheel is drawn and processed, the outer edge size of the wheel is increased, the car pusher is limited at the inner side of the traveling rail, the car pusher is good in effect and strong in stability after being assembled and used, and the problem that the car pusher falls off the rail is avoided. The defect of abrasion of a trolley wheel shaft occurs after the heavy-duty car pusher is used for one year, the trolley wheel shaft and the trolley arm are designed into a whole, the trolley wheel shaft and the trolley arm cannot be disassembled in a split mode, ordered spare parts need to be ordered integrally, each spare part has 6000 yuan of value, and the replacement cost is high.

In the face of the problem, through careful research, and also under the inspired discovery of a threaded connecting rod when a billiard game is received, a split type cart arm is designed, a cart wheel shaft and the cart arm are in threaded connection, when spare parts are ordered again, only the cart wheel shaft is ordered independently, each spare part has a value of dozens of yuan, the maintenance cost is greatly reduced, the machining period of the spare parts is short, and the replacement is simple and convenient.

The heavy car pusher is a part of a car dumper system and is an important mechanical part for pushing a full-load coal heavy car into the car dumper, the cart arms of the domestic heavy car pusher are integrally cast, the cart arms can only be integrally replaced after being worn, the problem of car pusher derailment frequently occurs after the heavy car pusher is operated for a period of time, the problem that the design and the use of a running wheel rotating bearing of the original factory car pusher are unreasonable is found through careful observation and analysis, the original designed running wheel uses a self-aligning bearing, the shaking angle is large during running, and the problem of rail derailment caused by deviation of a rail is caused. The key of the smooth loading and unloading of the coal car is directly influenced by the operation reliability of the coal car, and the loading and unloading time of the coal car is too long, so that the state iron carries out vehicle backlog overtime economic assessment according to the regulation and the regulation, and certain economic loss can be caused to a company. Therefore, a cart arm structure of a heavy cart with excellent performance, economy, applicability and convenient and flexible replacement needs to be researched urgently.
