As a still further scheme of the invention: the induction movable rod comprises a movable rod which is hinged on the holding clamp arm and can swing, a reset piece for resetting the movable rod and a pressure sensor matched with the movable rod.

As a still further scheme of the invention: the clamp is characterized by further comprising a controller for controlling the clamping power source to act, and the input end of the controller is electrically connected with the pressure sensor.

As a still further scheme of the invention: the reset piece is a torsion spring.

As a still further scheme of the invention: and the holding clamp arm is provided with a mounting hole matched with the steering shaft.

Compared with the prior art, the invention has the beneficial effects that: the invention can realize the holding and clamping action in an exploration mode by driving the holding and clamping arms at the same side by different holding and clamping power sources, and can realize an emergency positioning holding and clamping mode to ensure the smooth work of the holding and clamping arms.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a split type clamping arm of a clamping type carrier comprises two groups of clamping mechanisms 2 arranged on a vehicle body 1, wherein each clamping mechanism 2 comprises a clamping power source 21 arranged on the vehicle body 1, a screw rod 22 in transmission connection with the clamping power source 21, a sliding table 23 moving along the screw rod 22, clamping arms 26 hinged to two sides of the middle of the vehicle body 1 through a steering shaft, and a push rod 25 connecting the clamping arms 26 and the sliding table 23, the clamping mechanisms 2 are symmetrically arranged along a traveling direction, and the two clamping arms 26 on the same side are respectively driven by different clamping power sources 21; an induction movable rod 27 for inducing pressure is arranged on one opposite side of the holding arm 26.

Optionally, the free end of the holding arm 26 is provided with a walking support wheel 28.

Optionally, an included angle exists between the rotation axis direction of the steering shaft of the holding arm 26 and the normal of the horizontal ground, so that the walking support wheel 28 is close to the ground when the holding arm 26 is in the unfolded state, and the walking support wheel 28 is far away from the ground when the holding arm is in the folded state.

As an alternative, the sensing movable rod 27 includes a movable rod hinged to the holding arm 26 and capable of swinging, a reset member for resetting the movable rod, and a pressure sensor matched with the movable rod.

As an optional scheme, the clamp device further comprises a controller for controlling the action of the clamping power source 21, and an input end of the controller is electrically connected with the pressure sensor.

Optionally, the reset member is a torsion spring.

Optionally, the clamping arm 26 is provided with a mounting hole 29 matched with the steering shaft.

The working principle of the invention is as follows: because the two holding clamp arms 26 on the same side are respectively driven by the two sets of holding clamp power sources 21, when the external sensing system cannot accurately position the tire position or the external sensing system is damaged, the holding clamp arm 26 close to one side of the tire is in a folded state, the holding clamp arm 26 far away from one side of the tire is in an unfolded state, a search mode is realized by moving the vehicle body 1, when the holding clamp arm 26 far away from one side of the tire touches the tire, the induction movable rod 27 on the induction movable rod is extruded and induces the tire position, and then the holding clamp arm 26 close to one side of the tire is correspondingly unfolded, so that an emergency positioning holding clamp mode can be realized, and smooth work of the vehicle is ensured.
