Description

Technical Field

[0001] The utility model relates to a mobile emergency water pump trolley, belonging to the field of emergency rescue equipment. Background Art

[0002] At present, with the progress of the times, more and more heavy objects need to be moved, and trolleys have become an indispensable means of transportation in production and life. They save time, effort and labor.

[0003] At present, in emergency rescue missions, when drainage operations are required, wheelbarrows are often used to transport water pumps. However, conventional wheelbarrows can only carry one water pump at a time, and other heavier accessories such as cables cannot be carried at the same time. Other wheels / manual transportation are required, or even multiple transportations are required. Special tools for smaller water pumps are easily lost during transportation, which is inconvenient to use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a mobile emergency water pump trolley.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0014] Beneficial effects of the utility model:

[0015] Through the design of the clamping mechanism, when adjusting the height of the top placement rack, the connection between the clamping rod and the guide rod can be released by rotating the turntable. After adjusting the height of the top placement rack, the turntable is released. At this time, under the action of the reset spring, the moving part resets and drives the clamping rod to be clamped into the through hole again, and then into the clamping groove at this height, thereby limiting the top placement rack to this height.

[0016] Through the design of the driving component, when adjusting the height of the top placement rack, the operator inserts his palm into one of the grooves, holds the turntable in the groove, and then rotates the turntable. The rotation of the turntable drives the rotating shaft to rotate, the rotating shaft drives the two gears to rotate, and the rotation of the gears drives the driven components on both sides to rotate.

[0017] Through the design of the driven component, the rotation of the gear drives the rack plates on both sides to move, and the rack plates on both sides drive the two moving parts to move, and the movement of the moving parts stores the clamping rod into the inner cavity.

[0018] Through the design of the enclosure mechanism, after the top placement rack moves vertically and the space between the bottom placement rack and the top placement rack is allocated, the fence rods on the bottom placement rack and the top placement rack can be pulled vertically, and the fence rods move stably under the guidance of several telescopic rods. After moving to a suitable position sufficient to cover the carried items, the fence rods are released. At this time, the fence rods are adsorbed together with the magnetic adsorption blocks at this position on the guide rods, and the fence rods are limited to this height position by the magnetic adsorption blocks on the four guide rods, ensuring that the fence formed by the fence rods and the telescopic rods can achieve the effect of enclosure.
