Problems solved by technology

In the construction site, when the formwork is removed, there will always be some discarded nails and cut wire buckles. If you are not careful, the tires of the tire-type dump rickshaw will be punctured. The maintenance of the tires is also very troublesome. The concrete materials may be delayed due to delays. Conveying beyond the initial setting time, resulting in waste of material
Unlucky defects of tire-type dump rickshaw: the material of the inner tire is easy to age and crack, the capacity of the dump is relatively small, and the maintenance of the vehicle is difficult, etc.
Defects of unlucky rail mine cars: old-fashioned mine cars are relatively heavy, the residues in the dead corners of square iron tanks are not conducive to cleaning, and the loading and unloading process is cumbersome, resulting in a waste of human resources

Embodiment 1

[0018] Example 1. Method for transporting concrete by using a rail car with buffer discharge and empty bucket reset

[0019] The method is as follows: the material hopper 1 and the frame 13 with rail wheels are combined into a rail trolley for loading and unloading to transport concrete; when loading, the splitter plate 9 in the material hopper 1 is used to control the concrete Load to make the material hopper 1 evenly loaded; when unloading, use the positioning device 23 and the buffer 7 connected with the frame 13 to loosen the material hopper 1 and control the discharge speed of the material hopper 1 respectively; after the discharge is completed, The material bucket 1 is reset by using the characteristics of the buffer spring 27 in the buffer.

[0020] The present invention specifically adopts a method including the following steps:

[0021] Loading: Use manual or mechanical means to charge the material hopper 1 and make the material hopper 1 evenly loaded under the action of th...

Embodiment 2

[0024] Example 2. Track trolley with buffer discharge and empty bucket reset

[0025] The structure of the rail car is as follows Figure 1 to Figure 6 As shown, it is mainly composed of a material bucket 1, a buffer 7, a frame 13 with track wheels, and a positioning device 23. The two sides of the material bucket 1 pass through the material bucket rotating shaft 10, the bearing 11 and the bearing seat 12 and the car The upper part of the two vertical rods of the frame 13 are movably connected, and the hopper push-pull handle 2 of the material hopper 1 is connected to the underframe of the frame 13 through a positioning device 23. The buffer 7 is mounted on the underframe of the frame 13.

[0026] The lower part of the material hopper 1 is semicircular, and the upper part is in the form of an opening. The edge of the upper mouth is sealed with steel bars or steel pipes, and two lugs are welded on the outside. The two ends of the push-pull handle 2 of the hopper are respectively co...

Abstract

The invention relates to a method for conveying concrete by adopting a track trolley with buffer unloading and empty bucket restoration, which comprises the following steps of: loading and unloading by utilizing a track trolley which combines a material bucket (1) and a trolley frame (13) with a track wheel to convey the concrete; during loading, controlling the loading of the concrete by utilizing a splitter plate (9) arranged in the material bucket (1), so that the loading of the material bucket (1) is uniform; during unloading, loosening the material bucket (1) and controlling the unloading speed respectively by adopting a positioning device (23) and a buffer (7) which are connected with the trolley frame (13); and after the unloading is completed, restoring the material bucket (1) by utilizing the characteristic of a buffer spring (27) in the buffer. The method can improve the conveying speed of concrete materials and reduce the manual labor strength, and has the advantages of simple, economic and practical operation, easy popularization and the like.

Description

Technical field [0001] The invention relates to the field of concrete construction, in particular to a method for transporting concrete in a construction site using a track trolley with buffer discharge and empty bucket reset. Background technique [0002] In concrete construction, the relatively closed construction area is not suitable for conveying concrete by pump truck. There are several methods used in the past. Among them, the reverse transportation using the wheeled dump rickshaw and the rail mining vehicle are the most common. In the construction site, when the formwork is removed, there will always be some abandoned nails and cut wire buckles. If you are not careful, the tires of the wheeled dump rickshaws will puncture, and the maintenance of the tires is also very troublesome. The concrete materials may be delayed due to delays. Conveying and exceeding the initial setting time, resulting in waste of materials. Defects of wheeled dump rickshaws: the material of the in...
