Description

Technical Field

[0001] The utility model belongs to the technical field of annular cooler construction auxiliary devices, in particular to a sintering annular cooler trolley wheel clearance adjustment device. Background Art

[0002] The sintering ring cooler usually consists of a frame, a horizontal rail device, a side rail device, a trolley and a rotating frame, a liquid-sealed air duct system, a blower system, a driving device, a feeding device, a unloading device (including a plate feeder), a ring cooling cover, an installation and measuring platform, etc. The trolley units are large in size and numerous in number. During installation, they are hoisted onto the horizontal track by a crane, and then the gap between the trolley wheels and the horizontal rails is adjusted.

[0003] The wheel clearance of the trolley is adjusted by hammering or prying with a crowbar. This adjustment method is inefficient, has poor precision control, and results in low trolley installation efficiency, which will ultimately affect the overall installation time of the sintering ring cooler.

[0008] Preferably, a triangular reinforcement plate is welded at the connection between the upright support and the support arm.

[0009] Beneficial Effects

[0010] The utility model has a simple structure and can be conveniently made of scrap steel on site. The traditional sintering trolley gap adjustment adopts a sledgehammer to hit the trolley wheel or a crowbar to pry the trolley wheel to force the wheel to shift to achieve the purpose of adjusting the trolley wheel gap. The adjustment method is laborious, time-consuming, and has poor adjustment accuracy control. The utility model is fixed on the cushion beam under the trolley wheel by the front support and the vertical support, and the wheel can be easily moved by using a jack with a top tool, which saves time and labor, and the adjustment data is accurately controllable, greatly improving the efficiency of the trolley wheel gap adjustment.

[0014] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0015] like Figure 1 As shown, the utility model discloses a sintering ring cooler trolley wheel gap adjustment device, comprising two arms 1 arranged in parallel on both sides, the ends of the two arms 1 are connected by a rear support 4, the middle section of the arm 1 is provided with a vertical support 3 protruding downward, the front end is provided with a front support 2 protruding downward, and the end of the front support 2 is provided with a hook 201. The distance from the upper surface of the hook 201 to the lower surface of the arm 1 matches the thickness of the upper wing plate of the trolley track 7, the length of the vertical support 3 should be at least equal to the thickness of the upper wing plate, and can be equal to the height of the trolley track 7 at most, so as to ensure that the upper surface of the trolley cushion beam can be supported. The distance between the front support 2 and the vertical support 3 is greater than the width of the trolley track 7, the distance between the two arms 1 is greater than the outer diameter of the trolley wheel 5, and a jack 6 is fixed on the inner side of the rear support 4, and the top rod of the jack 6 is parallel to the length direction of the arm 1 and faces the direction of the front support 2.

[0018] 1. Before installing the sintering ring cooler trolley, mark the radial line on the top surface of the trolley track 7 inside and outside the trolley to be installed;

[0019] 2. Lift the trolley onto the trolley track 7 and ensure that the radial lines of the inner and outer wheels of the trolley coincide with the radial lines of the track when in position;

[0020] 3. Use a steel ruler to measure the gap between the trolley wheel 5 and the track, compare it with the installation standard, and adjust the wheel gap on the side with the larger gap;

[0021] 4. Pass the open side of the front support 2 of the utility model through the wheel, ensure that the hook 201 is hooked on the upper wing plate of the track I-beam cushion beam, and the lower surface of the vertical support 3 is supported on the upper surface of the trolley cushion beam;
