Description

Technical Field

[0001] The utility model relates to the technical field of coal loading, in particular to a coal cake flattening machine for a coal loading vehicle. Background Art

[0002] The coal loading car is one of the main mechanical equipment used on the coking side of the tamping coke oven, and it runs on the coke oven machine side. Its main function is to cooperate with the tamping machine, feeder and smoke guide car to load the coal cakes into the coke oven carbonization chamber. The important components of the coal loading car are the running device, the front baffle device, the rear baffle device, the coal box device, the coal loading device, the coal cake flattening machine, the residual coal recovery device, the dust removal device, etc. Among them, the function of the coal cake flattening machine is to flatten the uneven coal cakes after tamping.

[0003] During the operation of the existing coal cake flattening machine, the base of the coal press is exposed and prone to coal accumulation, which requires manual cleaning. When cleaning the coal accumulation in the base, there is a risk of mechanical injury, and it is easy for personnel to step on empty space or get their feet injured. In addition, when repairing the tamping and feeding mechanisms, the platform has a slope, and the coal press wheel of the coal press is fixed, which is difficult to move out during maintenance, resulting in insufficient maintenance space and difficulty for personnel to perform maintenance.

[0004] Therefore, it is urgent to solve the problem of large amount of coal accumulation and difficult maintenance during the operation of the coal cake flattening machine. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a coal cake flattening machine for a coal loading vehicle, which can prevent coal accumulation, reduce the number of personnel cleaning up coal accumulation, and reduce workload, while providing a safe maintenance platform to facilitate maintenance and improve maintenance efficiency.

[0006] The utility model provides a coal cake flattening machine for a coal loading vehicle, comprising a traveling platform, a traveling mechanism, a flattening mechanism and a power mechanism, wherein:

[0007] The traveling platform comprises a coal press base, an anti-slip plate is provided on the upper side of the coal press base, and traveling tracks are provided on both sides of the upper part;

[0008] The running mechanism comprises a moving seat, which is horizontally arranged above the base of the coal press, and a group of pillars are respectively arranged on both sides of the moving seat, and a running wheel is respectively arranged at the lower end of each pillar, and the running wheel can be movably mounted on the running track;

[0009] The flattening mechanism comprises a coal pressing wheel connecting shaft, one end of which is detachably connected to one side of the movable seat, and the other end of which is provided with a coal pressing wheel seat, the lower end of which is connected to a movable pull rod, and the other end of which is connected to the coal pressing wheel;

[0010] The power mechanism includes a driving sprocket and a transmission sprocket located at both ends of the running track. The driving sprocket is equipped at the power output end of the reducer. The reducer is connected to the power output end of the motor by transmission. The transmission sprocket is installed on the transmission wheel seat. A transmission chain is installed between the driving sprocket and the transmission sprocket. The two ends of the transmission chain are respectively connected to two pillars on the same side of the moving seat.

[0011] Preferably, the movable seat is provided with a socket, the coal pressure wheel link shaft is detachably mounted in the socket, and a limit block is threadedly mounted at the outlet of the socket.

[0012] Preferably, the coal pressure wheel seat includes a wheel seat body, which is a hollow square columnar structure, with strip slide grooves on both sides of its upper part, slide rods movably mounted in the strip slide grooves, sliding bearings mounted at both ends of the slide rods, and the coal pressure wheel connecting shaft is connected to the sliding bearings.

[0013] Preferably, the coal pressing wheel comprises a group of pressing rollers, each of which is provided with a group of rolling bearings, and the two pressing rollers are respectively mounted on both ends of the roller shaft through the rolling bearings, and a pulling seat is provided in the middle of the roller shaft.

[0014] Preferably, a guide plate is movably installed in the lower part of the coal pressure wheel seat, a limit plate is provided at the bottom, a movable pull rod passes through the limit plate and its upper end is connected to the guide plate, and its lower end is connected to the pull seat.

[0015] Preferably, the number of the flattening mechanisms is two or more.

[0016] Working principle of the utility model: When the coal cake flattening machine for coal loading vehicles of the utility model is used, the motor is started to rotate alternately forward and reverse, and the motor drives the driving sprocket to rotate through the reducer, thereby driving the transmission chain to rotate. Under the traction of the transmission chain, the rotating running mechanism reciprocates on the running platform, and the flattening mechanism reciprocates with the running mechanism. At this time, the coal pressing wheel rolls back and forth on the coal cake to flatten the coal cake. When the running mechanism switches the reciprocating direction, the slide bar first slides upward in the strip slide groove, and then slides downward when the wheel seat body is vertical, so that the wheel seat body changes the tilting direction, which is convenient for the flattening mechanism to perform the flattening coal compaction operation under the traction of the running mechanism. During the major maintenance operation, after the limit block is disassembled, the coal pressing wheel connecting shaft can be directly pulled out, and the running platform can be used as a maintenance platform. The maintenance personnel can directly stand on the anti-slip plate on the upper part of the running platform for maintenance.

[0017] Beneficial effects of the utility model: the coal cake flattening machine for coal loading vehicles of the utility model has an external straddle type running mechanism, that is, the running wheels are arranged on the outside of the running platform, 180 channel steels are installed on both sides of the coal press base to form two running tracks, and welded patterned steel plates are laid on the top of the coal press base as anti-skid plates to form a closed running platform. This structure can effectively prevent coal powder from accumulating into the bottom trough of the coal press, reducing the number of personnel cleaning coal powder, and the blocking of the running platform can enable maintenance personnel to stand directly on the anti-skid plate on the upper part of the running platform for maintenance during maintenance tamping and feeding operations, providing a maintenance platform for maintenance of other equipment. At the same time, the connection between the coal press wheel connecting shaft and the moving seat in the device is detachable, and the coal press wheel connecting shaft can be unplugged at any time during major maintenance operations, and the running platform can be used as a maintenance platform to facilitate platform movement and further facilitate maintenance. In addition, the two ends of the transmission chain are connected to the two pillars on the same side of the moving seat, which are close to the coal pressing wheel, so that the flattening machine is not easy to deflect when traveling, making the flattening machine run more smoothly. Therefore, the coal cake flattening machine for coal loading vehicles of the utility model can effectively prevent the generation of coal accumulation, reduce the number of personnel cleaning coal accumulation operations, reduce the workload, and provide a safe maintenance platform, facilitate maintenance, improve maintenance efficiency, and the device runs stably and reliably with a high safety factor.
