[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] A monitoring device that can rotate and lift, such as Figure 1 and 2 As shown, it includes a telescopic column mechanism and a rotating monitoring rod mechanism, and the telescopic column mechanism includes a fixed column 1, a first telescopic column 2, a second telescopic column 3, a first lifting structure 4 and a follow-up lifting structure;

[0023] A first lifting structure is installed in the fixed column 1, and the lifting part of the first lifting structure is connected to the first telescopic column 2 and drives the first telescopic column 2 to slide in the fixed column 1. The first lifting structure can adopt a motor screw transmission structure or a piston cylinder lifting structure, mainly for the purpose of vertical support and lifting of the first telescopic column. The present embodiment adopts a motor screw transmission structure. In order to facilitate the later assembly, a groove is provided at the bottom of the fixed column to expose the motor housing part. Because the motor screw transmission structure is a prior art, it is not elaborated here. In order to achieve the connection with the first telescopic column and drive the lifting, the first telescopic column has a bottom plate, and the bottom plate is provided with a hole. The lifting nut of the motor screw transmission structure is penetrated in the hole and fixedly connected in the hole. The part of the screw is extended into the cavity of the first telescopic column. Because the second telescopic column is installed in the inner cavity of the first telescopic column, if the second telescopic column is long enough, it is necessary to provide a clearance hole for the screw to pass through the bottom plate of the second telescopic column. If the length of the second telescopic column is not enough to contact the screw, then there is no need to set a clearance hole for the screw to pass through.

[0024] like Figure 2 and 3As shown, the second telescopic column 3 is slidably installed within the first telescopic column 2. The follow-up lifting structure includes a follow-up fixed wheel 51, a follow-up reversing wheel 52, and a follow-up flexible connecting member 53. The follow-up fixed wheel 51 is installed within the fixed column 1 and is located below the first telescopic column. The follow-up reversing wheel 52 is installed on the first telescopic column 2. One end of the follow-up flexible connecting member 53 is connected to the portion of the first telescopic column 2 located within the fixed column, preferably installed on the outer side of the bottom plate of the first telescopic column. The other end of the follow-up flexible connecting member 53 passes through the fixed column after bypassing the follow-up fixed wheel 51, and then bypasses the follow-up reversing wheel 52 to achieve direction change. The follow-up reversing wheel is installed at the top of the second telescopic column. After direction change, the follow-up flexible connecting member enters the first telescopic column and is connected to the second telescopic column, which can be connected to the bottom plate of the second telescopic column or to the side wall. The follow-up lifting structure is symmetrically installed to avoid uneven force.

[0025] In this embodiment, the follow-up fixed wheel 51 and the follow-up reversing wheel 52 are sprockets, and the follow-up flexible connecting member 53 is a chain. Of course, a structure can also be adopted where the follow-up fixed wheel 51 and the follow-up reversing wheel 52 are pulleys, and the follow-up flexible connecting member 53 is a steel cable.

[0026] For the purpose of ensuring linear movement during lifting and preventing tipping, a limit guiding structure is provided around the top of the fixed column to surround the first telescopic column; a limit guiding structure is also provided around the top of the first telescopic column to surround the second telescopic column. The limit guiding structure includes a limit seat 61 and a limit guide wheel 62. The limit guide wheel is installed on the limit seat and the limit guide wheel is in rolling contact with the outer wall of the first telescopic column or the outer wall of the second telescopic column. The rolling contact of the limit guide wheel with the telescopic column helps the telescopic column to lift linearly on the one hand, and on the other hand, it can also provide a radial force to the telescopic column to further prevent it from tipping.

[0027] In this embodiment, the fixed column, the first telescopic column, and the second telescopic column are all square columns. In order to achieve all-round limitation, a limit guiding structure is provided on both sides of each corner of each square column. That is to say, a total of eight limit guiding structures are provided at the four corners.

[0028] The first telescopic column is supported by the first lifting structure, and the side wall of the fixed column can also limit the lateral force of the first telescopic column to prevent it from tilting. Similarly, for the second telescopic column within the first telescopic column, the lateral force is provided by the side wall of the first telescopic column to prevent it from tipping, and the vertical supporting force is provided by the tightened follow-up flexible connecting member.

[0029] In addition, a limit column is provided at the top of the fixed column and the top of the first telescopic column. The limit column is mainly provided to prevent the first telescopic column and the second telescopic column from being completely retracted, so that they maintain a certain exposed length. Moreover, after being raised, they will not be completely exposed, but will remain in the telescopic channel, and bear the limiting force provided by the side wall of the telescopic channel to prevent them from falling.

[0030] The rotating monitoring rod mechanism is installed on the top of the second telescopic column. Figure 1 and 2 As shown, the rotating monitoring rod mechanism 7 includes a monitoring rod 71 and a rotating structure, and the rotating structure includes a rotating fixed gear 72, a rotating motor 73, and a rotating main gear 74; the rotating fixed gear 72 is fixed on the top of the second telescopic column, and the end of the monitoring rod is installed on the rotating fixed gear and rotates relative to the rotating fixed gear; specifically, the rotating connection can be achieved through bearings and pins, and the rotating motor 73 is installed on the monitoring rod and the output shaft of the rotating motor is installed with a rotating main gear 74, and the rotating main gear 74 is meshed with the rotating fixed gear 72. The rotating motor rotates with the rotating main gear, and the rotating main gear meshes around the rotating fixed gear to achieve rotation, and the monitoring rod rotates around the rotating fixed gear to finally achieve the swing of the monitoring rod. This embodiment realizes monitoring of different angles of 180 degrees.

[0031] In this embodiment, in order to monitor different horizontal positions, the monitoring rod used is a telescopic rod. The telescopic rod can adjust the monitoring angles of different horizontal positions, realize changes in different heights, different radiation angles and different horizontal positions, and realize multi-point monitoring. The monitoring rod includes a fixed rod 75, a telescopic rod 76 and a telescopic structure, the telescopic structure is installed in the fixed rod and the telescopic part of the telescopic structure is connected to the telescopic rod, and the telescopic rod is slidably installed in the fixed rod; and a monitoring device installation position is provided on the fixed rod and / or the telescopic rod. The telescopic structure can use a telescopic electric cylinder, a hydraulic cylinder, etc. as long as it can achieve telescopic.

[0032] The working process of lifting is:

[0033] The first lifting structure lifts and lowers the first telescopic column. When the first telescopic column rises, since one end of the follower soft connector 53 is connected to the first telescopic column, this end will rise together with the first telescopic column. Under the limitation of the follower fixed wheel and a certain length, the other end of the follower soft connector 53 will synchronously drive the second telescopic column to move upward to achieve synchronous extension.

[0034] When descending, when the first telescopic column descends, since one end of the follower flexible connection member 53 is connected to the first telescopic column, this end portion will descend along with the first telescopic column. Under the limitation of the follower fixed wheel and with a certain length, the other end of the follower flexible connection member 53 will synchronously drive the second telescopic column to move downward, achieving synchronous retraction.

[0035] Through an active first lifting structure and a follower lifting structure, the lifting of the two telescopic columns can be synchronously achieved, the height of the monitoring device can be quickly adjusted, and multi-angle monitoring can be realized by rotating the monitoring rod mechanism.
