Abstract

The utility model belongs to special equipment used to overhaul a locomotive running portion, in particular to a support trolley used to support a locomotive body. Wheel set shafts are respectively arranged under symmetrical vertical beams of a trolley frame through bearing seats arranged on the left side and the right side, each wheel set shaft is provided with two wheels, a central disc locating sleeve matched with a location central pin of the locomotive body is arranged on a cross beam in the center of the trolley frame, beam faces on the center of the symmetrical vertical beams are fixedly connected with a support block respectively, and the support blocks are matched with the bottom face of the locomotive body. The support trolley used to support the locomotive body is simple in structure, convenient to use, flexible, low in manufacturing cost and wide in use range, and capable of replacing an expensive car lifting jack and improving use ratio of the car lifting jack and overhaul progress of a locomotive.

Description

A kind of support chassis that supports locomotive car body

Technical field

The utility model belongs to the specialized equipment of locomotive under repairing traveling section, particularly a kind of support chassis that supports locomotive car body.

Background technology

The GKIC locomotive is when maintenance traveling section, locomotive car body top need to be lifted with car lifting J-Horner, then two chassis releasing locomotive running gear decompose maintenance, along with locomotive constantly increases, the locomotive inspection and repair unwheeling is frequent, but car lifting J-Horner only has one, it is longer that particularly locomotive medium-term repair takies the car lifting J-Horner time, just caused other locomotive inspection and repair difficulty, return repair in shop if run into the large needs of chassis fault during maintenance, that just not only causes the car lifting J-Horner holding time long, and causes the space for maintenance holding time long, and affects finishing of scheduled overhaul task.

Summary of the invention

The purpose of this utility model is to provide a kind of support chassis that supports locomotive car body, and it is simple in structure, and is easy to use, maneuverability, low cost of manufacture can be replaced out expensive car lifting J-Horner, improve the degree of utilization of car lifting J-Horner, can improve the repair schedule of locomotive, range of use is wide.

The purpose of this utility model is achieved in that a kind of support chassis that supports locomotive car body, wheel is installed respectively to axle at the longeron of vehicle frame symmetry below by the bearing seat of arranged on left and right sides setting, two wheels are installed respectively at every wheel on to axle, crossbeam at the vehicle frame center is arranging the spider locating bush that matches with locomotive car body center of location pin, at the supercentral beam face of the longeron of symmetry affixed back-up block respectively, back-up block matches with the bottom surface of locomotive car body.

During locomotive under repairing, utilize car lifting J-Horner that locomotive car body top is lifted, two chassis releasing locomotive running gear decompose maintenance, then two chassis of the present utility model are pushed the locomotive car body bottom and fall car lifting J-Horner, locomotive car body just steadily is placed on the chassis of the present utility model, has reached the purpose of replacement and the at any time conversion of space for maintenance of car lifting J-Horner.Greatly make things convenient for locomotive inspection and repair, improved the repair schedule of locomotive.

When will lifting locomotive car body, car lifting J-Horner falls, two center of location pins will fall in two spider locating bushs supports on the locomotive car body, locomotive car body steadily is placed in four supports in the bogie truck left and right sides, played the purpose that car lifting J-Horner is cemented out, the cooperation of locating dowel pin and locating bush has been played locomotive car body and has been guaranteed that when shifting space for maintenance car body and false chassis do not break away from, and guarantees safety.

The utility model is simple in structure, and is easy to use, maneuverability, and low cost of manufacture can be replaced out expensive car lifting J-Horner, improves the degree of utilization of car lifting J-Horner, has improved the repair schedule of locomotive, and range of use is wide.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing,

Fig. 1 is main TV structure scheme drawing of the present utility model;

Fig. 2 is the left TV structure scheme drawing of Fig. 1;

Fig. 3 is the plan structure scheme drawing of Fig. 1;

Fig. 4 is for using the utility model to support the structural representation of locomotive car body.

The specific embodiment

A kind of support chassis that supports locomotive car body, such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, wheel is installed respectively to axle at the longeron of vehicle frame 1 symmetry below by the bearing seat 2 of arranged on left and right sides setting, two wheels 3 are installed respectively at every wheel on to axle, crossbeam 4 at vehicle frame 1 center is arranging the spider locating bush 5 that matches with locomotive car body 7 center of location pins, at the supercentral beam face of the longeron of symmetry affixed back-up block 6 respectively, back-up block 6 matches with the bottom surface of locomotive car body 7.When locomotive car body 7 center of location pins when locating bush 5 on the vehicle frame 1 matches, back-up block 6 matches with the bottom surface of locomotive car body 7.

Result of use of the present utility model:

1, car lifting J-Horner can be replaced out other locomotive of frame, 200,000 yuan of the buying expenseses of saving car lifting J-Horner, 2, locomotive car body is placed on the utility model chassis at any time conversion space for maintenance, do not resemble and be placed on active the car lifting J-Horner and account for space for maintenance, 3, since the utility model chassis support interval not resemble the car lifting J-Horner support interval large, and long-time support can not cause car body flexural deformation, 4, greatly improved the repair schedule of locomotive, and result of use is good aspect maintenance.

The utility model be mainly used in GKIB type, GKIC type, CKID type, etc. mining-type locomotive frame vehicle overhauling, range of use is wide.

Claims
