Roadblock device with spline type guide device and use method

Abstract

A roadblock device with a spline type guide device comprises a body frame (1), an internal telescopic mechanism and a roller device, wherein the body frame (1) forms an obstacle body of the roadblock device, the internal telescopic mechanism is arranged in an internal cavity, and the roller device is arranged on the lower portion of the body frame (1). The internal telescopic mechanism comprises a driving motor (14) and a threaded shaft (17), the driving motor (14) is mounted at the internal upper end of the body frame (1), the threaded shaft (17) is connected with the driving motor through power and matched with an internal thread of a threaded sleeve (16), a plurality of longitudinally extending spline grooves (161) circumferentially and uniformly formed in the outer circumferential surface of the threaded sleeve (16), a shell of the driving motor is fixedly connected with a guide spline sleeve (15), and the spline sleeve (15) is in sliding fit with the spline grooves (161) of the threaded sleeve (16) to form the spline type guide device.

Description

technical field [0001] The invention relates to a roadblock device, in particular to a roadblock device with a splined guide device and a method of use, which is suitable for the application occasion of a heavy-duty roadblock device. Background technique [0002] Roadblocks often need to be set up at the intersections of some roads or the entrances of areas to control road traffic. For example, to prohibit the passage of vehicles or to prohibit the passage of motor vehicles exceeding the norms. [0003] These barriers usually need to be adjusted according to the actual needs of road traffic or area access control. This therefore requires movement of the barricade. [0004] Movable roadblock devices have appeared in the prior art. Compared with transmission roadblock devices, traditional devices are fixed on the road surface and cannot be adjusted in position, while this movable roadblock device can be adjusted in position. . [0005] However, the adjustment of the positi...

AI Technical Summary

Problems solved by technology

[0005] However, the adjustment of the position of such roadblocks is often time-consuming and laborious

Especially when the barricade itself is required to have considerable weight to prevent vehicles from forcibly entering or driving, the movement of this barricade is particularly difficult

Moreover, some barricades themselves have other undesired effects on regulated road traffic
