Abstract

The utility model relates to a hoisting machine, in particular to an engine hoist with a safety device, which solves the technical problems that the safety performance of the existing hoisting machine is low and the structure is complex. The technical scheme is that the engine hoist comprises a base, installed with traveling rollers at the bottom part, a stand column hinged on the base and two support arms, two supporting bars are hinged on the base, and the other ends of the two supporting bars are hinged on the stand column; and a cantilever is hinged at the top end of the stand column, a hoisting hook is positioned at the right end of the cantilever and the two ends of an oil cylinder are respectively hinged on the stand column and the cantilever. The utility model is characterized in that two safety baffles and a safety pin are arranged on the stand column, the two safety baffles are vertically arranged on the two sides of the cantilever, and a plurality of positioning holes matched with the safety pin are manufactured on the edge of the safety baffles.

Description

A kind of engine loop wheel machine with safety device

Technical field

The utility model relates to a kind of elevator machinery, is specially the engine loop wheel machine with safety device.

Background technology

In the automobile repair process, often need check or repair the engine of automobile.Generally need to adopt the engine loop wheel machine that engine is hung out automobile, engine is placed on the Engine frame fixes again, remove loop wheel machine then engine is overhauled.Conventional engine loop wheel machine (Fig. 5) comprises that the bottom is equipped with the base of road wheel, and pivotally attached column and two legs also are hinged with two strut bars on the base on the base, and the other end of two strut bars all joins on column; The top of described column is hinged with a cantilever, and the right-hand member of cantilever is positioned with a suspension hook, and other has the two ends of an oil cylinder to be hinged on respectively on column and the cantilever.

The defective of this type of engine loop wheel machine is: during work, engine need be fixed on Engine frame, and it is very not convenient to operate; Oil cylinder need bear the most pressure of cantilever, in case emergency situations such as generation oil cylinder leakage of oils, the engine that cantilever and cantilever are sling tenesmus suddenly brings danger to the maintainer, and potential safety hazard is bigger.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of engine loop wheel machine is provided, and this engine loop wheel machine should have safety performance height, characteristic of simple structure.

The technical scheme that the utility model provides is: a kind of engine loop wheel machine with safety device, described engine loop wheel machine comprises that the bottom is equipped with pivotally attached column and two legs on the base, base of road wheel, also be hinged with two strut bars on the described base, the other end of two strut bars all is hinged on the column; The top of described column is hinged with a cantilever, and the right-hand member of cantilever is positioned with a suspension hook, and other has the two ends of an oil cylinder to be hinged on respectively on column and the cantilever; It is characterized in that: also be provided with two safe plate washer and safety pins that are arranged vertically on the cantilever both sides on the described column, the edge of described safe plate washer is shaped on the knock hole that some and described safety pin cooperates.

Knock hole on the described safe plate washer all is symmetrical arranged.

The beneficial effects of the utility model are: owing to be provided with safety device, enable safe plate washer and safety pin supporting cantilever during work, just can directly overhaul engine, no longer need special-purpose Engine frame, and operation is also very convenient; In addition, just in case accident takes place, safety pin also can bear the pressure of cantilever, and cantilever can not dropped, and has improved the safety of crane when mobile; Simultaneously, the more original crane of the utility model has only increased by two safe plate washers and a safety pin, and simple in structure, cost is lower.

The specific embodiment

As shown in Figure 1, road wheel 1-1 (quantity of road wheel can be determined as required, is 4 among the figure) is equipped with in the bottom of base 1 of the present utility model, is hinged with a column 3 and two legs 2 on the base, the end of two legs respectively is equipped with a road wheel 1-1, makes the mobile more convenient of loop wheel machine.

Also be hinged with two strut bars 4 (as shown in Figure 1) that are arranged vertically on column 3 both sides on the base, the other end of two strut bars all is hinged on the column 3; The top of described column 3 and cantilever 6 are hinged by a bearing pin; There is a suspension hook 7 the right-hand member location (hinged by bearing pin) of cantilever 6; Also have the two ends of an oil cylinder 5 to join respectively on column 3 and cantilever 6 in addition.

Improvement part of the present utility model is: be arranged vertically 8, two safe plate washers of two fan-shaped safe plate washers on the described column 3 and laid respectively at the both sides of cantilever 6 and be parallel to each other; The scallop of two safe plate washers 8 is along the knock hole 8-1 that is shaped on some symmetries (number in hole determines as required, is 6 on every safe plate washer among Fig. 1); Other has a safety pin 9 can pass two symmetrical knock holees cantilever 6 is positioned.

Can according to actual needs safety pin be inserted in different knock holees during use, as Fig. 2, different conditions shown in Figure 3; After work is finished, pull out safety pin, cantilever is reset to state as shown in Figure 4.
