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] Embodiment 1. Adopt the method for transporting concrete by rail trolley with buffer unloading and empty bucket reset

[0019] The method is: use the rail trolley combined with the material hopper 1 and the vehicle frame 13 with rail wheels to carry out loading and unloading to transport concrete; Loading, so that the material hopper 1 is evenly loaded; when unloading, use the positioning device 23 and the buffer 7 connected to the vehicle frame 13 to loosen the material hopper 1 and control the discharge speed of the material hopper 1 respectively; after the unloading is completed, Utilize the characteristic of the buffer spring 27 in the buffer to reset the material hopper 1.

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

[0021] Loading: use manual or mechanical means to load the material hopper 1, and under the action of the diverter plate 9, the material hopper 1 can be loaded evenly;

[0022] Unloading: Transport t...

Embodiment 2

[0024] Embodiment 2. Rail trolley with buffer unloading and empty bucket reset

[0025] The structure of the track trolley is as follows Figure 1 to Figure 6 As shown, it is mainly composed of a material bucket 1, a buffer 7, a vehicle frame 13 with rail wheels and a positioning device 23, wherein: the two sides of the material bucket 1 are connected to the vehicle through the material bucket rotating shaft 10, bearing 11 and bearing seat 12. The tops of the two vertical bars of the frame 13 are movably connected, and the hopper push-pull handle 2 of the material hopper 1 is connected with the underframe of the vehicle frame 13 through the positioning device 23 . Buffer 7 is contained on the underframe of vehicle 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 splitter plate 9 is welded...

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 on a construction site by using a rail trolley with buffer discharge and empty bucket reset. Background technique [0002] In concrete construction, relatively closed construction areas are not suitable for transporting concrete by pump trucks. There are several methods used in the past, among which the use of tire-type dump rickshaws and rail mine carts is the most common. 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 dump rickshaw will be punctured, and the maintenance of the tires is also very troublesome. The concrete materials may be delayed due to delays. Transportation exceeds the initial setting time, resulting in waste of materials. The unlucky defects of the tire-type dump rickshaw: the material of the inner tir...
