Abstract

The utility model relates to a shock-proof and anti-dropping device for a crane. The device is characterized in that welding plates are symmetrically and fixedly mounted at a guiding rail at the lower end of a crane end beam, the lower end surfaces of the welding plates are connected with connecting plates, an L-shaped guard plate is fixedly mounted on the lower end surface of each connecting plate, a gap is reserved between the guard plate and the guiding rail, blocks are arranged on two sides of the guard plate and fixedly connected with the connecting plates. Therefore, the utility model has the advantages of simple structure, convenient installation, high safety performance and the like.

Description

Hoisting crane antidetonation anti-drop device

Technical field

The utility model belongs to hoisting crane and makes the field, particularly relates to a kind of hoisting crane antidetonation anti-drop device.

Background technology

Hoisting crane is widely used in fields such as lifting loading and unloading, travelling car and car load are component parts important in the hoisting crane, when crane end carriage or guide rail generation vibration, dislocation may take place even deviate from both, there is very big potential safety hazard in this situation, and existing hoisting crane does not have this type of device to prevent that guide rail breaks away from.

Summary of the invention

The utility model provides a kind of simple in structure, easy for installation, hoisting crane antidetonation anti-drop device that performance is high for solving the technical matters that exists in the known technology.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

A kind of hoisting crane antidetonation anti-drop device, it is characterized in that: symmetry is fixed with welded plate at guide rail place, the lower end of crane end carriage, the welded plate lower surface is connected with connecting panel, the lower surface of connecting panel is fixed with L-shaped backplate, backplate and guide rail leave the gap, the backplate both sides are provided with block, and block is captiveed joint with connecting panel.

The utility model can also adopt following technical measures:

It is 10mm～15mm that described backplate and guide rail leave gap width.

Advantage and the good effect that the utlity model has are: owing to be fixed with welded plate at guide rail place, the lower end of crane end carriage, the welded plate lower surface is connected with connecting panel, the lower surface of connecting panel is fixed with L-shaped backplate, backplate and guide rail leave the gap, the backplate both sides are provided with block, block is captiveed joint with connecting panel, the utility model does not contact with guide rail when the hoisting crane normal operation, when vibration or dislocation take place in both, L shaped backplate of the present utility model can hook guide rail, prevent the hoisting crane getaway, so said structure is simple, easy for installation, the safety performance advantages of higher.

Fig. 4 is Fig. 3 left view.

Among the figure: 1, welded plate; 2, connecting panel; 2-1, bolt; 3, backplate; 4, block; 5, end carriage; 6, guide rail.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 to Fig. 4,6 places are fixed with welded plate 1 at the lower end of crane end carriage 5 guide rail, and the welded plate lower surface is connected with connecting panel 2 by bolt 2-1, and the lower surface of connecting panel is fixed with L-shaped backplate 3, backplate and guide rail 6 leave the gap, and gap width is 10mm～15mm.The present embodiment gap width is 10mm, backplate 2 both sides are provided with block 4, block is captiveed joint with connecting panel 2, block 4 plays the 2 intensity effects of reinforced company's fishplate bar, the utility model does not contact with guide rail when the hoisting crane normal operation, and when vibration or dislocation took place for both, L shaped backplate of the present utility model can hook guide rail, prevent the hoisting crane getaway, so said structure is simple, easy for installation, the safety performance advantages of higher.
