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. Rail trolley with buffer unloading and empty bucket reset

[0019] 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.

[0020] 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...

Embodiment 2

[0030] Example 2. The application of the track trolley with buffer discharge and empty bucket reset in transporting concrete

[0031]When in use, the rail trolley is used for loading and unloading to transport concrete. When charging, the diverter plate 9 provided in the material hopper 1 is used to control the loading of concrete, so that the material hopper 1 is evenly charged. 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; Material hopper 1 is reset.

[0032] Described track car specifically adopts the step that comprises following use:

[0033] Loading: Use the diverter plate 9 inside the material hopper 1 to control the loading of concrete, so that the material hopper 1 is evenly loaded;

[0034] Unloading: Transport the loaded track trolley to the construction area for unloading. When unloading, pull the positioning h...

Abstract

The invention relates to a small railcar with buffering unloading and empty hopper resetting integrated by a material hopper (1) and a frame (13) with a rail wheel, wherein the small railcar mainly comprises the hopper (1), a buffer (7), the frame (13) and a locating device (23); the two sides of the hopper (1) are movably connected with the upper parts of the two upright rods of the frame (13) through a hopper rotating shaft (10); a locating pin (6) of the hopper (1) is connected with the bottom frame of the frame (13) via the closing of the locating device (23); and the buffer (7) is installed on the bottom frame of the frame (13). The small railcar can increase the reverse conveying speed of concrete material, reduce labour intensity, and has the advantages of simple operation, low cost, practical use, easy popularization and the like.

Description

technical field [0001] The invention relates to the field of concrete construction, in particular to a track trolley with buffer discharge and empty bucket reset for transporting concrete at a construction site. 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 tire is easy to age ...
