Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As shown in Figure 2, it is the structure that cold bed of the present utility model lifts steel dolly, comprise the translation mechanism of electrical system control and the elevating mechanism of HYDRAULIC CONTROL SYSTEM, described translation mechanism is provided with trolley translation guide groove and little guide wheel, described little guide wheel is placed in trolley translation guide groove, and formation is slidably matched.
In order to solve prior art Problems existing and overcome its defect, the goal of the invention of the abrasion realizing minimizing guide wheel and the damage avoiding bearing, the technical scheme that the utility model is taked is:
As shown in Figure 2 and Figure 3, cold bed of the present utility model lifts steel dolly, and described translation mechanism is also provided with translation guide wheel guide rail 202 and the large guide wheel 201 of translation, and the large guide wheel 201 of described translation rolls on translation guide wheel guide rail 202; The diameter of the large guide wheel of described translation 201 is greater than little guide wheel.
In Fig. 2, the utility model comprises improved translation guide wheel 201, translation guide wheel guide rail 202; The sprocket wheel 203 that active major axis is moved forward and backward by driven by motor whole group of dolly, the connection chain 204 connecting initiatively major axis sprocket wheel.
Technique scheme guarantees that cold bed lifts steadily movement after steel Plantago minuta, reduces fault rate, reduces guide wheel abrasion and bearing damage.
The utility model provide above-mentioned utilize 10 groups of large guide wheels to substitute 48 groups of little guide wheels lift steel dolly.Specifically, move in parallel after driving 8 groups to lift steel Plantago minuta by 10 groups of large guide wheels, change the little guide wheel under each holder steelframe, simplified by original support guide effect, it is made to play the guiding role, alleviate the stressed degree of little guide wheel, thus reduce the fault rate, the minimizing influence time that lift steel dolly, reduce material consumption.
To be segmentation install large guide wheel lifting below steel dolly to the utility model, instead of all transform large guide wheel as by whole section, ensureing to lift under the prerequisite that steel dolly normally runs like this, save makings, installation cost, reduction accident rate shortens maintenance time and manpower and materials consumption greatly.
The diameter of the large guide wheel 201 of described translation is 17cm.The additional translational guide wheel that cold bed of the present utility model lifts steel dolly is transformed original little guide wheel lifting steel dolly, and the large guide wheel utilizing diameter to be 17cm connects and lifts steel dolly two ends, guarantee 8 groups lift steel Plantago minuta after move in parallel.
The large guide wheel 201 of described translation is supported on the upper surface of translation guide wheel guide rail 202, and described little guide wheel and the inner bottom surface of trolley translation guide groove are at a distance of 2mm.
Because its height is a little more than the little guide wheel 2mm on former holder steelframe when large guide wheel is installed, make original little guide wheel change original force way, guiding before and after only plaing a part, the gravity lifting steel dolly is all distributed on the new large guide wheel 201 of translation installed.
Described translation guide wheel guide rail 202 is arranged on the two ends lifting steel dolly, and its width is 10cm, and length is 280cm.
Total length 90m lift steel dolly front end, centre, rear end select 5 groups and lift steel dolly, wide in the erection of its rear and front end is 10cm, the long I-steel for 280cm is as guide rail, the guide wheel connection utilizing diameter to be 17cm lifts steel dolly two ends, its height is a little more than the little guide wheel 2mm on former holder steelframe, little guide wheel stress is alleviated, only play guided in translation effect, stress point is transferred to above large guide wheel, large guide wheel diameter is large, low at the little guide wheel of moving process medium speed ratio, its intensity is higher than little guide wheel in addition, not fragile.
The large guide wheel 201 of described translation is located at the top of melt pit.
Because the large guide wheel 201 of translation is erected at above melt pit, it is few to add its quantity, and easy-to-search after breaking down, repairs convenient, fast; Meanwhile, potential safety hazard is decreased.
Due to the utility model original cold bed lifted to the transformation of the translation guide wheel of steel dolly, make its mounting and adjusting convenience, save making, mounting cost, greatly reduce replacing, overhaul time and the manpower consumption of former little guide wheel, thoroughly solve translating trolleys guide wheel frequent breakage, check and change loaded down with trivial details drawback.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
