Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway transportation equipment, namely a device for opening and closing train compartment doors. Background Art
[0002] In the prior art, water-quenched slag (also known as water slag), one of the by-products in the blast furnace production process of the iron smelting plant, has potential hydraulic cementitious properties. Under the action of activators such as cement clinker, lime, and gypsum, it can be used as a high-quality cement raw material. It needs to be sold to cement production units and is generally divided into road transportation and rail transportation during transportation. When transporting by rail, the doors of the train compartments need to be blocked before loading the water slag to prevent the water slag from spilling during transportation. When opening and closing the compartment doors, the door bolts are pried open with a crowbar and a hammer while installing wooden wedges. After completion, foam glue is used to plug the door. Since the compartment doors cannot be opened and closed quickly, the working hours of the personnel on duty are wasted, and the transportation time is also affected.
[0003] Before using this product, human labor is required to open and close the train compartment doors and install wooden wedges using crowbars and hammers, which takes a long time and is extremely inconvenient. Utility Model Content
[0004] The purpose of the utility model is to provide a device for opening and closing train compartment doors, which is conducive to the rapid opening and closing of train compartment doors and saves time and effort, in view of the above-mentioned shortcomings.
[0005] The technical solution of the utility model is: a train compartment door opening and closing device, which is characterized in that it comprises a handle, a door bolt stopper convex upwardly at the front end of the handle, a rectangular iron plate convex downwardly welded to the front of the handle, at least two hook pin adjustment holes are spaced apart on the rectangular iron plate, a movable hook is connected to one of the hook pin adjustment holes, and a hook head is provided at the front end of the movable hook.
[0006] A nut for installing a pin is welded at the tail end of the movable hook.
[0007] The utility model has the advantages of providing a special tool, playing a quick role in opening and closing the door of a train compartment, reducing labor intensity, being simple to manufacture and convenient to operate.
[0008] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a simplified structural diagram of the utility model.
[0010] Figure 2 It is a simplified structural diagram of the utility model in use state. DETAILED DESCRIPTION
[0011] See also Figure 1 , 2The names of the parts are as follows: handle 1, bolt block 2, movable hook 3, hook pin adjustment hole 4, pin 5, rectangular iron plate 6, compartment door 7, train compartment 8, bolt block 9, bolt 10, hook head 11, installation wooden wedge 12.
[0012] See also Figure 1 The train compartment door opening and closing device comprises a handle 1 made of round steel or threaded steel, the front end of the handle 1 has a convex bolt stopper 2, and a convex rectangular iron plate 6 is welded at about 1 / 3 of the front of the handle 1 for mounting a movable hook 3. The rectangular iron plate 6 has at least two hook pin adjustment holes 4 spaced apart, and a movable hook 3 is connected to one of the hook pin adjustment holes 4, and a hook head 11 is provided at the front end of the movable hook 3. The movable hook 3 of corresponding size is made of round steel or threaded steel, the front end is bent into an angle of about 145°, and a nut is welded at the tail end for mounting the pin 5. Two orifice plates are welded at about 1 / 3 of the distance between the handle 1 and the end of the welded iron block 6.
[0013] See also Figure 2 , Usage: When opening and closing the door 7, the movable hook 3 hooks the bottom of the train compartment 8, the welded rectangular iron plate 6 is used as the bolt stop 9 to support the bolt 10, and the manpower goes up to the stage to press the bolt 10 tightly, and quickly installs or removes it. It plays a quick role when opening and closing the door 7 of the train compartment 8, reducing the labor intensity.
[0014] The above description is only a specific implementation of the present utility model, and various examples do not constitute a limitation on the essential content of the present utility model.
