This cast steel major possession molding sand box lifts by crane unsettled support in the motion process that equipment railway carriage or compartment lifted and descend, and operating personnel all need not get into equipment railway carriage or compartment bottom to thoroughly solved operating personnel's potential safety hazard.
Description
Technical Field
The utility model relates to a safety supporting facility for hoisting and suspending a large cast steel molding sand box.
Background
The safety support is an essential part in the hoisting suspension use of the large cast steel molding flask, and particularly, when an operator lifts an equipment compartment to enter the bottom of the equipment compartment for maintenance, great potential safety hazards exist, and the condition that the hoisting suspension of the large cast steel molding flask must be provided with a safety device for preventing the equipment compartment from self-descending is clearly specified, namely the commonly-called hoisting suspension safety support of the large cast steel molding flask.
However, in a device with a short wheelbase and no auxiliary safety supporting rod device, because the space of the chassis is limited, if the safety supporting rod device is installed at the front side of the lifting suspension device, that is, the safety supporting rod device is turned over from front to back around a safety supporting pin fixed on the lifting suspension device when in use, the conventional safety support (as shown in fig. 3) cannot be arranged, the safety support interferes with parts such as a lifting device of a device compartment, and the safety supporting rod device can only be installed at the rear side of the lifting suspension device.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, provides a safety support facility for hanging a large cast steel molding flask, has stable structure and flexible and convenient operation, is suitable for short-wheelbase auxiliary-free safety support rod device equipment, and can greatly improve the maintenance efficiency and safety factor of hanging the large cast steel molding flask.
In order to achieve the purpose, the utility model adopts the following technical scheme: a safety supporting facility for hoisting and suspending a large cast steel molding flask comprises a safety supporting seat and a safety supporting rod device, wherein the tail end of the safety supporting rod device is arranged on the rear side of the safety fixed supporting seat through a safety supporting pin shaft and can rotate around the safety supporting pin shaft; the top end of the safety supporting rod device is fixedly arranged in a clamping groove of a safety supporting clamp, the safety supporting clamp is arranged on a bottom plate of the equipment compartment, the hoisting suspension device is fixed on the safety supporting rod device, and a support is arranged on the hoisting suspension device, is connected through a support pin shaft and can rotate around the support pin shaft; the handle is arranged on the rod wall of the safety supporting rod device, so that an operator can conveniently rotate the safety supporting rod device to a proper angle. When the hoisting suspension device is provided with the fixing bolt, the screwing torque is larger than 220Nm, the hoisting suspension device is easy to fix, and the safety factor of the whole equipment is increased.
The utility model has the beneficial effects that: 1. the safety supporting rod device is arranged at the rear side of the hoisting suspension device, so that the problem that the safety support cannot be arranged on the short-wheelbase chassis is solved; 2. by using the utility model, an operator can limit the safety supporting rod device through the rotating bracket without always holding the safety supporting rod device, and the operator does not need to enter the bottom of the equipment compartment in the lifting and descending movement process of the equipment compartment, thereby thoroughly solving the potential safety hazard of the operator.
Drawings
FIG. 1 is a state diagram of the present invention in use;
FIG. 2 is a top plan view of the present invention when not in use;
FIG. 3 is a schematic view of the mechanism for lifting a suspended safety support for a conventional cast steel large molding flask;
the lifting suspension device comprises a lifting suspension device 1, a support 2, a safety supporting pin shaft 3, a safety supporting rod device 4, a handle 5, a safety supporting clamp 6 and a support pin shaft 7.
Detailed Description
The utility model is further illustrated with reference to the following figures and examples.
As shown in fig. 1.2, the hoisting suspension support for the large cast steel molding flask comprises a hoisting suspension device 1 and a safety support rod device 4, wherein the tail end of the safety support rod device 4 is installed at the rear side of a safety fixed support seat 1 through a safety support pin shaft 3 and can rotate around the safety support pin shaft 3; the top end of the safety support rod 4 is fixedly arranged in a clamping groove of the safety support clamp 6, the safety support clamp 6 is arranged on the bottom plate of the equipment compartment, the hoisting suspension device 1 is fixed on the safety support rod device, and the hoisting suspension device 1 is provided with a bracket 2 which is connected through a bracket pin shaft 7 and can rotate around the bracket pin shaft 7; the handle 5 is welded on the rod wall of the safety supporting rod device 4. Wherein the bolt tightening torque for fixing the safety support seat 1 is more than 220 Nm.
As shown in fig. 2, when the steel casting large molding flask hoisting suspension safety support is not used, the safety support rod device 4 is flatly placed at the inner side of the safety support rod device, and the bracket 2 is arranged at the inner side of the safety support rod 4; as shown in fig. 1, when a suspended safety support needs to be lifted by a large cast steel molding flask, an operator first grasps a handle 5 to rotate a safety support rod 4 to a proper angle, then rotates a support 2 around a support pin 7 counterclockwise by 90 degrees to the lower part of a safety support rod device 4, then places the safety support rod device 4 on the support 2, the safety support rod device 4 is limited by the support 2, the operator leaves the bottom of a spare carriage, and finally drops the equipment carriage to the safety support rod device 4 to complete the operation.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
