[0002] The crossbeam is a beam perpendicular to the longitudinal beam, arranged along the short axis of the building. The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation.

The material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well. The construction period is short. It has a high degree of industrialization and can be produced in a highly mechanized specialized manner. Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing.

[0034] Combine the following Figure 1-11 Further explain the utility model;

[0035] It comprises a crossbeam 1, with mounting sleeves 3 fixedly connected to both ends of the crossbeam, and the two mounting sleeves are respectively connected to two pillars 2.

[0036] The crossbeam 1 includes a hollow support beam 1-1, and the front and rear sides of the hollow support beam are connected to a pressure plate 1-2. The upper end surface of the pressure plate is higher than the upper end surface of the hollow support beam, and the lower end surface of the pressure plate is lower than the lower end surface of the hollow support beam. The hollow support beam and the pressure plate are an integrally formed structure.

[0037] An annular support frame 4 is sleeved on the outer side of the cross beam, and two walking mechanisms 5 with the same structure and arranged opposite to each other are arranged on the annular support frame, one of which is arranged at the top of the inner wall of the annular support frame, and the other is arranged at the bottom of the annular support frame. The walking mechanism can drive the annular support frame to move along the length direction of the cross beam;

[0038] The walking mechanism comprises a support plate 5-1, and the support plates of the two walking mechanisms are respectively connected to the top and bottom of the inner wall of the annular support frame through a connecting frame 5-2.

[0039] The support plate is provided with a plurality of slide grooves 5-3, each of which is provided with an elastic support component, and the annular support frame is supported on the cross beam through the elastic support components on the two support plates.

[0040] The elastic support assembly includes a slider A5-4, which is slidably arranged in a slide groove. The length of the slider A is smaller than the length of the slide groove. An extrusion spring A5-5 is fixedly connected to the inner side of the slider A, and the other end of the extrusion spring A is fixed to the side wall of the slide groove. The slider A is fixedly connected to a telescopic rod A5-6 at the end away from the support plate, and a support block 5-7 is fixed to the other end of the telescopic rod A. An extrusion spring B5-8 is sleeved on the outside of the telescopic rod, one end of the extrusion spring B is fixed on the slider, and the other end of the extrusion spring B is fixed on the support block. A roller A5-9 is installed on the end of the support block away from the telescopic rod, and a roller B5-10 is installed on the outer side of the support block (the side facing the pressure plate).

[0041] A telescopic rod B5-11 is fixed to the middle of the support plate, and a motor bracket 5-12 is fixed to the other end of the telescopic rod B. An extrusion spring C5-13 is sleeved on the outside of the telescopic rod B. One end of the extrusion spring C is fixed to the support plate 5-1, and the other end of the extrusion spring C is fixed to the motor bracket 5-12. A dual-axis motor 5-14 is installed on the motor bracket, and driving wheels 5-15 are installed on both output ends of the dual-axis motor.

[0042] The driving wheels of the two walking mechanisms are in contact with the upper and lower surfaces of the hollow support beam of the crossbeam respectively, the rollers A on each elastic support component of the two walking mechanisms are also in contact with the upper and lower surfaces of the hollow support beam, and the rollers B on each elastic support component are in contact with the pressure plates on the front and rear sides of the crossbeam.

[0043] Anti-skid rubber pads 1-3 are fixed on the upper and lower surfaces of the hollow support beam at the walking tracks of the two driving wheels corresponding to the walking mechanism. The anti-skid rubber pads can increase the friction between the driving wheels and the hollow support beam to prevent the driving wheels from slipping when driving.

[0044] The operation of the dual-axis motor can drive the annular support frame to move along the length direction of the beam. The setting of the extrusion spring C can provide extrusion force to the motor bracket, so that the driving wheel abuts against the anti-slip rubber pad. Even if the beam is deformed, the driving wheel can still maintain abutment with the anti-slip rubber pad, thereby ensuring that when the beam is deformed, the walking mechanism can also drive the annular support frame to move along the length direction of the beam, thereby improving the adaptability of the device.

[0045] By setting the extrusion spring A, an extrusion force can be provided to the slider A, thereby indirectly making the roller B abut against the pressure plate, and by setting the extrusion spring B, an extrusion force can be provided to the support block, thereby making the roller A abut against the hollow support beam. Even if the beam is deformed, the elastic force of the extrusion spring A and the extrusion spring B can ensure that the roller A and the roller B are always abutted against the hollow support beam and the pressure plate. Therefore, when the beam is deformed, the elastic support mechanism can also support the annular support frame.

[0046] An annular slide rail 6 is fixedly installed on the annular support frame, and a plurality of sliders B6-1 are slidably connected in the annular slide rail, and also includes an annular gear ring 7, which is fixedly connected to the slider B in the annular slide rail; a motor 8 is fixedly installed on the top of the annular support frame, and a rotating shaft is connected to the motor output shaft, and a driving gear 8-1 is fixed on the rotating shaft, and the driving gear and the annular gear ring are meshed; the working of the motor can drive the annular gear ring to rotate, and a Z-shaped frame 9 is fixed on the annular gear ring, and a high-definition camera 10 for taking pictures and detecting the appearance of the beam is arranged on the Z-shaped frame;

[0047] The coordinated use of the annular slide rail and the slider B can limit the annular gear ring and improve the stability of the annular gear ring during rotation, thereby improving the stability of the camera position during adjustment.

[0048] By starting the motor to drive the shaft to rotate, the driving gear is driven to rotate synchronously, thereby driving the annular gear ring that meshes with it to rotate, and driving the detection camera to make a circular motion around the beam, the detection position of the camera can be adjusted to facilitate the shooting and detection of multiple surfaces of the beam, thereby facilitating multi-directional detection of the beam and improving the accuracy of the detection results.

[0049] A control panel 11 is arranged on one of the pillars 2; a display screen and control buttons are arranged on the control panel; and a wire is connected between the camera and the display screen.

[0050] The surface of the beam is photographed and tested by a high-definition camera, and the photographed images are transmitted to the display screen on the control panel for the staff to view, so that the staff can check whether the beam is rusted, cracked or deformed. Both the high-definition camera and the control panel are products available on the market.

[0051] A clamping hole is respectively arranged on the four sides of the inner wall of the installation sleeve 3, and an installation cavity 2-1 is arranged inside the two pillars 2, and the installation cavity is located at the upper part of the pillar.

[0052] The device cavities of the two pillars are provided with a clamping mechanism 12, which includes a cross bracket 12-1, the four end faces of the cross bracket are respectively fixed on the four side walls of the device cavity, four fixing plates 2-3 are fixed on the top inner wall of the device cavity, the cross bracket is rotatably connected with a support shaft 12-2, the support shaft passes through the middle of the cross bracket, the upper end of the support shaft is rotatably connected with the top inner wall of the device cavity, the lower end of the support shaft is fixed with a turning handle 12-3, and the support shaft located above the cross bracket is fixed with an active bevel gear 12-4. The four fixed The fixed plates 2-3 are arranged in a circular array around the support shaft, and each fixed plate is rotatably connected with a threaded drive rod 12-5, which penetrates the fixed plate, and each threaded drive rod is fixed with a driven bevel gear 12-6 at one end facing the active bevel gear, and the driven bevel gears at the ends of the four threaded drive rods are all meshed with the active bevel gear on the support shaft; the other end of each threaded drive rod is threadedly sleeved with a clamping block 12-7, and the end of the clamping block away from the fixed plate movably penetrates the pillar 2 and extends to the inside of the clamping hole of the corresponding mounting sleeve. That is, the column is provided with a hole for the clamping block to pass through at the position corresponding to each clamping block, and the clamping block can slide inside the hole.

[0053] An operating port connected to the device cavity is opened on the front of the pillar, and a protective door 2-4 is provided on the operating port. By arranging the clamping mechanism in the device cavity, the worker can close the operating port through the protective door when there is no need to rotate the handle, so that the device cavity is in a closed space, so that the clamping mechanism can be closed and protected to avoid the clamping mechanism being exposed to the outside, thereby protecting the clamping mechanism from rust and damage due to the influence of the external environment, thereby greatly improving the service life of the clamping mechanism.

[0054] During installation, the workers put the installation sleeves at both ends of the beam on the top of the pillar, open the protective door, and then manually rotate the handle to drive the support shaft to rotate, drive the active bevel gear to rotate, and synchronously drive the driven bevel gear meshing with it to rotate, and drive the threaded drive rod to rotate, so that the clamping block with threaded connection on the outer surface moves toward the clamping hole until the clamping block is embedded in the clamping hole, thereby achieving the clamping fixation of the installation sleeve, thereby achieving the fixed installation of the beam and the pillar.

[0055] Working principle: During installation, the installation sleeves at both ends of the beam are placed on the top of the pillar, and the pillar and the installation sleeves are clamped and fixed by the clamping mechanism and the clamping hole, so as to achieve the fixed installation of the beam and the pillar;

[0056] When the beam is installed and put into use, the dual-axis motor is started, and the output end of the dual-axis motor rotates to drive the drive wheel to rotate. The friction between the drive wheel and the anti-slip rubber pad is used to drive the annular support frame to move along the length of the beam, thereby driving the high-definition camera to move. The surface of the beam is photographed and inspected by the high-definition camera, and the captured images are transmitted to the display screen on the control panel for the staff to view the captured images.
