Abstract
The utility model discloses an automatic retracting device for a track, which belongs to the field of mechanical manufacturing and overcomes the defect that the track of a crane in prior art cannot be lengthened automatically. The automatic retracting device for the track mainly comprises a platform which is provided with a fixed track. The fixed track is provided with an upper trolley. The platform is provided with a retracting track and two or more than two groups of supporting devices. The supporting devices are fixed on the platform and each supporting device comprises a bracket, a cross shaft, a bearing A and an adjusting bolt. The retracting track is placed on the supporting devices and provided with a movable track blocking rod A and a movable track blocking rod B. The upper trolley is provided with a front push rod and a rear push rod. The utility model is mainly used in the field of mechanical manufacturing and can be also used in other fields.
Description
Technical field
The utility model belongs to mechanical manufacturing field, specifically, relates in particular to a kind of track automatic extending-contracting apparatus.
Background technology
In the production process of machine manufacture, the crane that moves in orbit, its track is fixed, and the length of track is also fixed; When crane arrives the end points of track, toward contact out of reach desired location, can move though carry the vehicle of trapped orbit, there is obstacle or unsettled the front; As: the stokehold discharging machine, in this case, and the length of a crane parking stall of lengthening, crane needs the strong point of front-wheel; Eventful could the solution of often need having given up, when useless worker was useless, labour intensity was big, and safety is low; Efficient is low, uses electric device or fluid pressure drive device at some places, and cost is all than higher.At present, also there is not a kind of device that can stretch automatically to address this problem.
Summary of the invention
The purpose of the utility model provides a kind of track automatic extending-contracting apparatus, to solve the defective that crane runway can not extend automatically in the prior art.
The utility model is to adopt following technical scheme to realize: a kind of track automatic extending-contracting apparatus, comprise platform, and platform is provided with trapped orbit, and trapped orbit is provided with the top dolly; Platform is provided with flexible track and two groups or two groups of above bracing or strutting arrangements; Bracing or strutting arrangement is fixed on the platform, and bracing or strutting arrangement comprises support, transverse axis, bearing A and adjustable bolt; Flexible track is placed on the bracing or strutting arrangement, and flexible track is provided with movable rail blocked shot A and movable rail blocked shot B; Push rod and rear push-rod before the top dolly is provided with.
Said track automatic extending-contracting apparatus preferably is provided with three groups of bracing or strutting arrangements;
Said track automatic extending-contracting apparatus can be provided with two groups or two groups of above clamping devices, and clamping device comprises vertical pivot, bearing B and is installed in the clamping wheel on the vertical pivot;
Said track automatic extending-contracting apparatus preferably is provided with three groups of clamping devices.
Compared with prior art, the beneficial effect of the utility model is: saving of work and time, and labour intensity is little, and is safe, high efficiency, and self does not need special power driven.

The specific embodiment
A kind of track automatic extending-contracting apparatus comprises platform 1, and platform 1 is provided with trapped orbit 6, and trapped orbit 6 is provided with top dolly 2; Platform 1 is provided with flexible track 5, three groups of clamping devices 7 and three groups of bracing or strutting arrangements 8; Bracing or strutting arrangement 8 is separately fixed on the platform 1 with clamping device 7; Bracing or strutting arrangement 8 comprises support 15, transverse axis 13, bearing A14 and adjustable bolt 16; Flexible track 5 is placed on the bracing or strutting arrangement 8, and flexible track 5 is provided with movable rail blocked shot A3 and movable rail bearing B 9; Top dolly 2 be provided with preceding push rod 4 ' with rear push-rod 4; Clamping device comprises vertical pivot 10, bearing B11 and is installed in the clamping wheel 12 on the vertical pivot 10.
The principle of work of the utility model is: when moving forward to low order end under the effect of top dolly 2 at electrical motor; Before push rod 4 ' act on movable rail blocked shot B9; The track 5 that will stretch is released forward, thereby, the distance that can extend the bodywork length of a top dolly 2 forward; When top dolly 2 moved backward, rear push-rod 4 acted on the movable rail blocked shot A 3 on the flexible track 5, and feasible flexible track 5 is return backward.
When using the utility model, the utility model is installed on the vehicle, will lifts operating-controlling mechanism and be installed on the top dolly 2 and get final product.
