Description

Technical Field

[0001] The utility model relates to a clamping device, in particular to an electric clamping device for a rod-shaped antenna. Background Art

[0002] According to the requirements of different communication tasks, multiple rod antennas can be installed on the lifting rod. When the lifting rods are raised one by one, the rod antennas are also raised accordingly, and corresponding communication operations can be carried out; when the lifting rods are retracted, the multiple rod antennas are also lowered one by one.

[0003] According to work needs, the lifting pole for installing the rod-shaped antenna needs to be transported by vehicle to the designated location to carry out communication tasks. During transportation, the vehicle is severely bumpy due to road conditions, and the antenna shakes greatly, which may cause damage or breakage of the antenna in severe cases.

[0004] In the prior art, there is no clamping and fixing device on the transport vehicle that can better fix the rod-shaped antenna to prevent the antenna from being damaged or broken due to the bumps of the vehicle during driving. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an electric clamping device for rod-shaped antennas. During the transportation of the lifting rod, the utility model can firmly clamp multiple rod-shaped antennas on the lifting rod to prevent the antennas from being damaged due to vehicle bumps.

[0006] In order to solve the above technical problems, the utility model provides an electric clamping device for a rod-shaped antenna, which is characterized by comprising vertical plate-shaped clamping bodies located on the left and right sides and a driving mechanism for driving the clamping bodies on the left and right sides to be in clamping and opening states, clamping blocks are symmetrically installed on the relative inner sides of the clamping bodies on the left and right sides from top to bottom, and a clamping space for accommodating the rod-shaped antenna is formed between the clamping blocks on both sides.

[0007] As an improvement of the utility model, the clamping block is fixed to the relatively inner side of the clamping body through the front and rear clamping plates, and the front and rear clamping plates and the clamping body as well as the front and rear clamping plates and the clamping block are all connected and fixed by fastening bolts.

[0008] Furthermore, longitudinal strip holes are respectively provided on the clamping bodies on the left and right sides, and the fastening bolts used for connecting and fixing the front and rear clamping plates to the clamping bodies pass through the longitudinal strip holes.

[0009] Furthermore, transverse strip holes are provided at positions of the front and rear clamping plates corresponding to the longitudinal strip holes on the clamping body, and the fastening bolts for connecting and fixing the front and rear clamping plates to the clamping body pass through the transverse strip holes.

[0010] As another improvement of the present utility model, the driving mechanism includes a self-locking lead screw installed in a box-shaped housing and a reduction motor for driving the rotation of the lead screw. The left side of the self-locking lead screw has a left-handed thread, and the right side has a right-handed thread. At the bottoms of the left and right vertical plate-shaped clamping bodies, nuts installed on the left and right sides of the self-locking lead screw are respectively fixed. Driving the reduction motor can make the left and right vertical plate-shaped clamping bodies be in two states: clamping and opening.

[0011] Furthermore, a long strip-shaped hole penetrating through the front and rear is opened at the upper part of the box-shaped housing. At the tops of the left and right nuts, connecting plates with a "凵" cross-section are respectively fixed. At the bottoms of the left and right clamping bodies, seat plates are respectively fixed. The front and rear ends of the connecting plates extend out from the front and rear ends of the long strip-shaped hole and extend upward above the box-shaped housing to be fixedly connected with the seat plates at the bottoms of the corresponding clamping bodies.

[0012] When the present utility model is in use, it is fixed on the vehicle body floor. One end of the rod-shaped antenna extends into the corresponding antenna clamping space. Operating the reduction motor can drive the left and right clamping bodies to be in the clamping state, and the antenna can be clamped in the clamping space, effectively preventing the antenna from generating large-amplitude vibrations during vehicle driving, and further preventing the antenna from being damaged or broken during transportation. After longitudinal strip-shaped holes are respectively opened on the left and right clamping bodies, the positions of the front and rear clamping plates in the vertical direction of the clamping body can be finely adjusted. After transverse strip-shaped holes are correspondingly opened on the front and rear clamping plates, the positions of the front and rear clamping plates in the horizontal direction of the clamping body can be finely adjusted, eliminating the installation error of the antenna, having stronger installation adaptability, and ensuring that the antenna can be completely clamped. In the present utility model, the front and rear ends of the connecting plate extend upward above the box-shaped housing to be fixedly connected with the seat plates at the bottoms of the corresponding clamping bodies, which can avoid the friction generated between the clamping body and the top of the box-shaped housing during the unfolding or clamping action.
