Abstract

The utility model discloses a bridge crane trolley. The utility model comprises a main hoisting mechanism, an auxiliary hoisting mechanism and a running mechanism, wherein the main hoisting mechanism, the auxiliary hoisting mechanism and the running mechanism are all arranged in an integral trolley frame, an inwards open type gear disk connecting hand which is arranged in a reel group of the running mechanism is directly sheathed on an outwards open type gear disk connecting hand of a low-speed shaft of a dotted line gear engaging type speed reducer, and a high-speed shaft of the speed reducer is connected with a drive shaft of a motor. The utility model can enhance product quality, can save material, can save labor, can reduce transportation expenses and can reduce composite cost.

Description

A kind of OTC's trolley

Technical field

The utility model relates to weight-lifting equipment, and particularly a kind of oad is little, bearing capacity big, steady quality, has the OTC's trolley of energy-saving and cost-reducing function.

Background technology

Existing 75t, 100t general-purpose overhead crane dolly, structure as shown in Figure 2, it is that a cover main hoisting mechanism 4 and a cover auxiliary hoisting mechanism 2 are installed on a split type trolley frame, also has a cover wheeling mechanism 3.It is a side in dolly split place 9 that main hoisting mechanism, operating unit are established, reel group 7 one ends connect an outward opening gear 8 in the main hoisting mechanism, the outward opening tooth engaged transmission of outward opening gear and A850 type reductor 6 slow-speed shafts, reductor high speed shaft are driven by electrical motor 5 again; Auxiliary hoisting mechanism is installed in the opposite side of trolley frame split place.The OTC's trolley of this structure is because unstable product quality and oad are big, not popular with users.In order to solve the unsettled shortcoming of quality, the product that has has adopted QJ series or A1570 retarder in main hoisting mechanism, but its profile big, still exist from heavy shortcoming.

Summary of the invention

The OTC's trolley that the purpose of this utility model is little, the steady quality of a kind of overall dimensions of design, load-carrying ability is high.

The technical solution of the utility model is finished as follows, it includes main hoisting mechanism, auxiliary hoisting mechanism and operating unit, it is characterized in that: main hoisting mechanism, auxiliary hoisting mechanism and operating unit are installed on the whole trolley frame, be provided with swing-in toothed disc catcher in the reel group of operating unit, swing-in toothed disc catcher directly is socketed on a kind of outward opening toothed disc catcher of dotted line gear mesh type reductor slow-speed shaft, and the reductor high speed shaft is connected with motor drive shaft.

The utility model not only overcome outward opening gear reel group quality instability, oad big, from heavy shortcoming, improve the quality of products, the saving in material cost-cutting, and owing to cancelled trolley frame and divided attachment structure, thereby removed the work capacity of factory manufacturing, user installation from, saved human cost; Its oad is little in addition, from heavy and light, reduces cost of transportation; Amount to every dolly cost and reduce by ten thousand yuan of 2-3.5.New departure has reduced the use amount of steel, has reduced the consumption of resources such as oil, electric power, coal, water indirectly, and very big social benefit is arranged.

Description of drawings

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of traditional 75t, 100t general-purpose overhead crane dolly.

Among the figure: 1, trolley frame; 2, main hoisting mechanism; 3, auxiliary hoisting mechanism; 4, operating unit; 5, electrical motor; 6, reductor; 7, reel group; 8, outward opening gear; 9, trolley frame split place.

The specific embodiment

The utility model is the improvement to existing 75t, 100t general-purpose overhead crane dolly, it includes main hoisting mechanism 2, auxiliary hoisting mechanism 3 and operating unit 4, be provided with swing-in toothed disc catcher in the reel group 7 of operating unit, swing-in toothed disc catcher directly is socketed on the outward opening toothed disc catcher of DZQ or DQJ dotted line gear mesh type reductor 6 slow-speed shafts, the high speed shaft of reductor 6 is connected with the axle drive shaft of electrical motor 5, and trolley frame 1 is whole trolley frame.Not only note in the development improving the in-use performance of main hoisting mechanism and reducing cost of product, and the commonality of attention part, most of parts can be used existing hoisting crane parts in the reel group, only need the swing-in toothed disc catcher in the redesign reel group; The connection structure of trolley frame split place 9 is cancelled, and whole trolley frame manufacturing process is convenient simple.

Claims

1, a kind of OTC's trolley, it includes main hoisting mechanism, auxiliary hoisting mechanism and operating unit, it is characterized in that: main hoisting mechanism, auxiliary hoisting mechanism and operating unit are installed on the whole trolley frame, be provided with swing-in toothed disc catcher in the reel group of operating unit, swing-in toothed disc catcher directly is socketed on a kind of outward opening toothed disc catcher of dotted line gear mesh type reductor slow-speed shaft, and the reductor high speed shaft is connected with motor drive shaft.
