Problems solved by technology

This kind of damping device depends entirely on the installation to ensure the pre-compression, and the damping effect is poor. At the same time, because the spring guide post is inserted into the end beam of the car body, the space is limited, and it is very difficult to disassemble.

Embodiment Construction

[0012] Such as figure 1 , 2 As shown, a hydraulic damping device for a tamping coal-charging car is installed with a support beam 2 at the bottom of the car body 1 between the running tracks of the tamping coal-loading car, and at least two are connected to the support beam 2 along the running direction. Hydraulic cylinder 3 (the present embodiment is two hydraulic cylinders), hydraulic cylinder 3 is powered by the hydraulic system 9 installed on the car body 1, hydraulic cylinder 3 is connected with support shoe 5 through joint bearing 4, corresponds to support shoe 5 in Support seat 6 is installed on the civil foundation below it. The joint bearing 4 can adjust the parallelism between the supporting surfaces.

[0013] In order to confirm that the support shoe 5 contacts or separates from the support seat 6 , a limit device 7 is installed between the hydraulic cylinder 3 and the support beam 2 .

[0014] In order to ensure safety, a camera 8 is installed at the bottom of t...

Abstract

A hydraulic damping device of a tamping coal charging car relates to an auxiliary device of a tamping coke oven. The damping mode of the existing tamping coal charging car, on the one hand, increases the rigidness of steel structure and reduces the vibration downwarping of the steel structure, thus enlarging the cost of the device and being hard to reduce the downwarping of a car body with the broadening of the rail distance of the coal charging car; on the other hand, the car body is provided with a spring damping device which has a poor damping effect and is hard to be dismounted and mounted. A supporting crossbeam is arranged at the bottom part of the car body between the tracks of the tamping coal charging car of the invention; a hydraulic cylinder is connected on the supporting crossbeam; the hydraulic cylinder is connected with a supporting boot by a joint bearing; a corresponding supporting pedestal is arranged on the foundation of the supporting boot. The invention can generate an upward supporting force relative to the car body to stop and limit the downwarping of the car body and reduce the wheel pressure generated by tamping briquettes, thereby ensuring the safe running of the device. The invention can be adapted to the large-scale developing requirements of coke oven machinery and has the advantages of reasonable structure design, good damping effect as well as convenient mounting and maintenance, etc.

Description

technical field [0001] The invention belongs to auxiliary equipment for a tamping coke oven tamping coal loading vehicle, and relates to a vibration damping device for a tamping coke oven tamping coal loading vehicle when tamping coal cakes. Background technique [0002] The tamping coal loading car is one of the key equipment for large-scale production and recovery of tamping coke ovens. It is arranged on the side of the coke oven and has the functions of tamping coal cakes, sending coal cakes into the carbonization chamber, and assisting the dust removal of the furnace door. . When the tamping coal loading vehicle is tamping coal cakes, it is subjected to the regular impact of the tamping hammer group, and the vehicle body vibrates up and down accordingly. The vibration intensifies the downward deflection of the steel structure, and its amplitude exceeds the downward deflection of the steel structure. The failure of the steel structure affects the stable operation of the ...
