Abstract
The utility model relates to a sand box locking equipment technical field especially relates to a special fixture is changed to sand box pattern draw round pin, including hoisting apparatus and ejector pin, the welding forms the ejector pin with the pipe by the steel sheet, and the ejector pin be the T style of calligraphy, and the pipe is through the strengthening rib and steel sheet fixed connection of its both sides, and hoisting apparatus be the jack, simple structure, and convenient operation, job stabilization is reliable, and the change that utilizes the simplest jack -up instrument jack completion to sell the pattern draw prevents that the spring from upspringing to lead to the fact bodily injury, effectively improves factor of safety and change efficiency.
Description
Technical field
The utility model relates to sandbox locking equipment technical field, particularly relates to a kind of sandbox lifting pin and changes unit clamp.
Background technology
Existing sandbox lifting pin adopts high-strength spring to be fixed in sandbox, takes the mode of artificial directly dismounting spring, it does not have supporting fixture during replacing, and spring can be upspring pin and pin cover, injures personnel safety.
Practical novel content
The technical problems to be solved in the utility model is: in order to solve existing replacing lifting pin by artificial, poor safety performance, changes the problems such as efficiency is low, and the utility model provides a kind of sandbox lifting pin to change unit clamp and solves the problem.
The utility model solves the technical scheme that its technical problem adopts: a kind of sandbox lifting pin changes unit clamp, comprises tackle gear and push rod, and push rod is welded by steel plate and circle pipe.
According to another embodiment of the present utility model, comprising push rod further is T font.
According to another embodiment of the present utility model, comprise round pipe further and it is connected with Interal fixation by the stiffening web of its both sides.
According to another embodiment of the present utility model, comprising tackle gear further is screw block.
The beneficial effects of the utility model are, structure is simple, easy to operate, and working stability is reliable, utilizes the simplest lifting gear screw block to complete the replacing to lifting pin, prevents spring from upspringing and cause personal injury, effectively improve safety coefficient and change efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is illustrated further.
Fig. 1 is structural representation of the present utility model.
In figure 1, tackle gear, 2, push rod, 3, steel plate, 4, circle pipe, 5, stiffening web.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now. These accompanying drawings are the schematic diagram of simplification, only with illustration, basic structure of the present utility model are described, therefore it only shows the formation relevant with the utility model.
If Fig. 1 is structural representation of the present utility model, a kind of sandbox lifting pin changes unit clamp, comprises tackle gear 1 and push rod 2, push rod 2 is welded by steel plate 3 and circle pipe 4, push rod 2 is T font, and circle pipe 4 is fixedly connected with steel plate 3 by the stiffening web 5 of its both sides, and tackle gear 1 is screw block.
During use, push rod 2 is placed on the sandbox lifting pin needing replacing, tackle gear 1 is placed on push rod 2, keep push rod 2 state vertical with tackle gear 1, then the depression bar of tackle gear 1 is manually pressed, the piston rod of tackle gear 1 is stretched out, top is to top part, then the standing bolt of lifting pin is backed out with allen wrench, come up the fastening screw of tackle gear 1, the piston rod of tackle gear 1 is slowly retracted, take off lifting pin, new lifting pin is put on flask drag, tighten the fastening screw of tackle gear 1, slowly manually press the depression bar of tackle gear 1, and the position of moment adjustment lifting pin is until lifting pin enters completely, the standing bolt of lifting pin is tightened with allen wrench, unclamp the fastening screw of tackle gear 1, piston rod is slowly retracted, complete sandbox lifting pin Renewal process.
Taking above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff in the scope not deviateing this practical new technique thought, can carry out various change and amendment completely. The content that the novel technical scope of this practicality is not limited on specification sheets, it is necessary to determine its technical scope according to right.
