Description

Technical Field

[0001] The present invention relates to the technical field of port machinery, and more specifically, to an anti-climbing device with wind-resistant and anti-slip detection functions. Background Art

[0002] Most of the rail-mounted cranes in ports have a high center of gravity and a large windward area. Wind-induced effects are an important cause of crane damage. One damage accident may cause cascade events nearby, resulting in serious damage to multiple cranes or even overturning. These accidents often occur because the wind load along the track direction of the crane is greater than the wind resistance of the crane, causing the crane to slide along the track direction and collide with other equipment or stop devices and overturn.

[0003] At present, most of the wind load tests on cranes are carried out by additionally carrying an anemometer to record the wind speed, and then the wind pressure caused by the wind speed and the windward area are calculated twice to obtain the wind load. In order to meet the wind protection requirements along the track, large track-mounted shore equipment is equipped with anti-climbing devices or track clamping devices, such as patent application CN201910509864.9. Although these wind protection devices can provide strong wind protection capabilities, they cannot accurately measure the size of the wind protection force. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiency of the existing anti-climbing device that it has no detection function, and to provide an anti-climbing device with anti-wind and anti-skid detection function, which can accurately measure the wind force that the port machinery can resist along the track direction and record and display the wind resistance status of the crane in real time, so as to provide data support for the formulation of anti-wind and anti-skid strategies for port machinery and the research and development of windproof devices.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent.

[0027] Example 1

[0028] like Figure 1 to Figure 2 The figure shows a first embodiment of an anti-climbing device with anti-wind and anti-skid detection functions of the present invention, comprising an opening and closing mechanism 2, a rail clamping mechanism 3, a wedge-shaped frame mechanism 4, a bracket 5, a roller 6, and a ladder frame 1 for fixed installation on the lower cross beam of the port machinery; the ladder frame 1 is connected to the top of the opening and closing mechanism 2, the opening and closing mechanism 2 is connected to the rail clamping mechanism 3, the bracket 5 is connected to the rail clamping mechanism 3, the wedge-shaped frame mechanism 4, and the roller 6, and the ladder frame 1 is provided with a wind force detection device 7 and a recording and display device 8 which is communicatively connected to the wind force detection device 7.

[0029] The track clamping mechanism 3 is a component that transmits and converts wind-proof force, converting the wind force received by the port machinery along the track into a track clamping force, thereby offsetting the wind force; the bracket 5 serves as a support; the opening and closing mechanism 2 can adjust the opening and closing of the track clamping mechanism 3 through the extension and contraction of the hydraulic cylinder. The working principle of the anti-climbing device is as follows: when the port machinery slides along the track under the action of wind force, the ladder frame 1 will move with the port machinery and apply a thrust to the wedge frame mechanism 4. When the opening and closing mechanism 2 is in a closed state, the thrust received by the wedge frame mechanism 4 will produce relative movement with the track clamping mechanism 3, so that the track clamping mechanism 3 produces a clamping force on the track. The clamping force changes with the relative displacement between the wedge frame mechanism 4 and the track clamping mechanism 3, thereby offsetting the wind force received by the port machinery along the track, so as to achieve the purpose of wind protection. When the opening and closing mechanism 2 is in a working state, the thrust received by the wedge frame mechanism 4 will not produce relative movement with the track clamping mechanism 3, and the port machinery can move normally at this time. Therefore, the lower end of the ladder frame 1 will produce a slight mechanical deformation in the process of transmitting wind force. By using the wind force detection device 7 to measure this mechanical deformation, the purpose of detecting the wind resistance and anti-skid ability of the port machinery can be achieved. The measured wind force is then recorded and displayed by the recording and display device 8, so that the operating personnel can view the wind force data intuitively.

[0030] In addition, the wind force detection device 7 includes a plurality of displacement sensors 71, which are connected to the ladder frame 1 through a bracket 72, and the displacement sensors 71 are in communication connection with the recording and display device 8. The displacement sensors 71 measure the small displacement of the ladder frame 1 under the wind force to obtain the current wind force.

[0031] The ladder frame 1 includes a support frame 11 and a plate frame 12 connected to both ends of the support frame 11. The displacement sensor 71 is located at one end of the plate frame 12 away from the support frame 11. The position of the displacement sensor 71 enables it to measure displacement more accurately. The displacement sensor 71 is detachably connected to the bracket 72 via a mounting plate 73. Figure 1 and Figure 2 As shown, the bracket 72 is formed into a triangle shape by welding three angle steels end to end; in this embodiment, a displacement sensor 71 is provided, and the mounting plate 73 is connected to the bracket 72 by threads, and the displacement sensor 71 is also connected to the mounting plate 73 by threads. Figure 1 and Figure 2 As shown, the platen frame 12 is connected to the lower surface of the support frame 11, and the lower end of the platen frame 23 extends to the roller 6, so that the displacement sensor 71 can be installed at a position close to the ground; since the platen frame 23 will deform during the loading process, and the deformation amount of its lower end is relatively large, the measurement error of the displacement sensor 71 can be reduced by detecting the deformation amount near the lower end. Figure 2As shown, the displacement sensor 71 is used to detect the distance between it and the inner wall of the platen frame 12, that is, the distance a; and is calculated by the following formula:

[0032]

[0033] In the formula, F represents concentrated load, L represents the length of the cantilever beam, E represents the elastic modulus, I represents the axial moment of inertia of the cross section, and L, E, and I are all constants, so the deformation f is linearly related to the concentrated load F. Therefore, when the anti-climbing device performs windproof work, the concentrated load F on the ladder frame 1 can be converted by measuring the deformation a of the ladder frame 1, and then the windproof force provided by the anti-climbing device can be obtained.

[0034] Among them, the recording and display device 8 is installed on the supporting frame 11. The recording and display device 8 includes a data processing module and a display module that is communicatively connected to the data processing module. The setting of the display module can facilitate the operator to intuitively view the displacement of the ladder frame. The recording and display device 8 also includes an alarm module that is communicatively connected to the data processing module. The setting of the alarm module can be used to prompt the operator. Specifically, the alarm module includes a plurality of LED lights, which are communicatively connected to the data processing module. The alarm module also includes a buzzer, which is communicatively connected to the data processing module. In this embodiment, the LED lights and the buzzer are both installed on the outer wall of the supporting frame 11.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the display module is a display screen, which is installed on the outer wall of the supporting frame 11. The recording and display device 8 can be used to display the displacement measured by the displacement sensor 71, that is, the deformation of the ladder frame 1; after data processing by the data processing module, the wind resistance and warning level of the fixed anti-climbing device corresponding to the displacement are displayed on the recording and display device 8. Specifically, different warning levels can be corresponding to different wind resistance intervals, such as: a green light is on in the range of 0 to 10t, and a normal state is displayed; a blue light is on in the range of 11 to 20t, and a mild warning is displayed; an orange light is on in the range of 21 to 30t, and a moderate warning is displayed; a yellow light is on in the range of 31 to 40t, and a severe warning is displayed; a red light is on when it is greater than 40t, and a serious warning is displayed, and a buzzer sounds at the same time. It should be noted that the color selection of the LED light and the range in which the buzzer sounds can be set according to the actual needs of the site.

[0036] Example 2

[0037] This embodiment is similar to embodiment 1, except that Figure 3As shown, two displacement sensors 71 are provided in this embodiment, and the two displacement sensors 71 are installed in the same side plate frame 12 and are located in a horizontal position. Through the dual sensor redundancy, the dual data are compared in real time, and the corresponding relationship between the actual loading force and the deformation of the ladder frame 1 can be obtained by tabulating the two sets of data and making a curve chart analysis. In addition, when one of the sensors has a problem, the other sensor can continue to work.
