Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable trench construction, in particular to a movable cable trench concrete pouring tool. Background Art
[0002] The side wall of the cable trench is cast by digging a trench for casting the side wall of the cable duct on the ground, and then building a template in the trench to form a casting trough, and pouring concrete into the trough to form the side wall.

The lifting plate 120 is slidably connected to the vertical bars 112, and the fixed plate 130 is fixedly connected to the vertical bars 112. The horizontal bars 111 and the vertical bars 112 form a rectangular guardrail shape for protecting the watering mechanism 200 and the operator fixed on the surface of the lifting platform.
[0034] Reference Figure 1 and Figure 2 The driving assembly 140 includes a threaded rod 141, a motor 142 and a controller (not shown in the figure). The threaded rod 141 passes through the lifting plate 120 and the fixed plate 130 in sequence. The threaded rod 141 vertically passes through the lifting plate 120 and the fixed plate 130. The lifting plate 120 is threadedly connected with the threaded rod 141, and the fixed plate 130 is slidably connected with the threaded rod 141.

When the hydraulic cylinder 410 is extended to the extreme position, the universal wheel 300 and the motor 142 are both suspended, and the operation is more stable.
[0037] The implementation principle of a movable cable trench concrete pouring tool in an embodiment of the present application is as follows: when the pouring tool arrives at the designated construction site, the hydraulic cylinder 410 is first started to press the support plate 420 downward to fix the pouring vehicle on the ground, and then the lifting plate 120 is adjusted according to the terrain to make the lifting plate 120 reach a suitable working height, and finally the pouring mechanism 200 fixed on the lifting plate 120 is started to operate.
[0038] After the pouring tool is fixed at the designated location, the motor 142 is started to drive the threaded rod 141 to rotate, so that the lifting plate 120 moves back and forth in the vertical direction. When the lifting plate 120 rises to a suitable working height, the motor 142 is paused through the controller, and the pump 220 pumps the concrete in the tank body 210 to the discharge pipe 230, and the discharge port 231 is aligned with the pouring trough of the side wall of the cable trench for pouring. This pouring method can greatly reduce the construction difficulty caused by narrow terrain.
