DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figures 1 to 8 , the present invention provides a technical solution:

[0026] A double-station foot buckle test device comprises a mounting frame 1, a variable diameter simulation pile 2, a tension controller 3, a pressing buckle assembly 4, a tension rope 5, a foot buckle climbing board 6 and a movable pulley 7. The variable diameter simulation pile 2 is vertically fixed on the mounting frame 1. The variable diameter simulation pile 2 comprises a conical arc plate 21, a variable diameter assembly 22 and a height adjustment assembly 23. Figure 2As shown, the reducing component 22 is used to simulate the actual situation that when the worker climbs from the bottom end of the pole to the top end, the diameter of the pole gradually becomes smaller. The reducing component 22 is fixed on the mounting frame 1, and the two conical arc plates 21 are slidably installed on the reducing component 22. The height adjustment component 23 connects the conical arc plates 21 and the reducing component 22 to control the sliding of the conical arc plates 21 in the reducing component 22. After the worker climbs up the pole, it is inconvenient for the worker to adjust the foot buckle climbing board 6 as the diameter of the pole becomes smaller, and the hanging angle of the foot buckle climbing board 6 on the pole changes. By adjusting the height adjustment component 23, the actual angle of the foot buckle climbing board 6 on the variable diameter simulation pile 2 is controlled, and the foot buckle climbing board 6 is hung on the variable diameter simulation pile 2 according to the working scene. On the two conical arc plates 21, the buckle assembly 4 is pressed tightly on the foot pedal of the foot buckle climbing board 6, simulating the situation of a worker stepping on the foot buckle climbing board 6, and simulating the situation of the foot buckle climbing board 6 being deformed and slipping due to the high load. A tension controller 3 is fixed under the mounting frame 1, and a winch drum 31 is installed on the tension controller 3. There is a fixed-length rope between the buckle assemblies 4, and the fixed-length rope is installed on the rope groove of the movable pulley 7. One end of the tension rope 5 is fixed on the bearing in the center of the movable pulley 7, and the other end is wound around the winch drum 31. When the tension controller 3 generates tension on the movable pulley 7, the movable pulley 7 can ensure that the two ends of the fixed-length rope always generate equal vertical downward tension on the two buckle assemblies 4.

[0027] As a preferred embodiment, the diameter reducing assembly 22 includes a telescopic rod I 221, an adjustment plate 222 and a slide rail plate 223. Figure 3 As shown, the two telescopic rods I 221 are divided into upper and lower layers in a horizontal state, one end of which is fixedly connected to one side of the mounting frame 1, and the other end is fixed to the adjustment plate 222. All telescopic rods I 221 are extended to simulate the increase in diameter, and shortened to simulate the decrease in diameter. There are holes on the adjustment plate 222, and an adjusting threaded rod 2231 is vertically arranged on one side of the slide plate 223. The threaded rod 2231 passes through the hole on the adjustment plate 222. Nuts are tightened on each adjusting threaded rod 2231 on both sides of the adjustment plate 222. The distance between the adjustment plate 222 and the slide plate 223 is controlled by adjusting bolts to simulate the initial diameters of rods of various specifications. A longitudinal slide rail is provided on the other side of the slide plate 223 to ensure that the conical arc plate 21 can only slide up and down on the slide plate 223. The other side of the mounting frame 1 is arranged in the same way to achieve left-right symmetry.

[0028] As a preferred embodiment, the telescopic rod I 221 not only includes linear power components such as hydraulic cylinders, but can also be mechanisms and components that achieve linear displacement such as four-bar mechanisms.

[0029] As a preferred embodiment, the distance control between the adjustment plate 222 and the slide rail plate 223 is not limited to the method of matching the threaded rod and the nut, but can also be achieved by stacking gaskets and the like to achieve distance fixing.

[0030] As a preferred embodiment, the height adjustment component 23 includes a lifting rod II 231, and the lifting rod II 231 vertically connects the adjustment plate 222 and the conical arc plate 21. Figure 4 As shown, the bottom end of the lifting rod II 231 is fixed on the bottom surface of the adjustment plate 222, and the top end of the lifting rod II 231 is fixedly connected to the bottom of the conical arc plate 21. When the rod diameter becomes smaller, the angle of the foot buckle climbing board 6 relative to the horizontal plane increases. When the rod diameter becomes larger, the angle of the foot buckle climbing board 6 relative to the horizontal plane decreases. The height adjustment component 23 controls the angle of the foot buckle climbing board 6 by adjusting the relative height of the two conical arc plates 21, and always keeps the height of the foot pedal of the foot buckle climbing board 6 unchanged.

[0031] As a preferred embodiment, the lifting and retracting rod II 231 not only includes linear power components such as hydraulic cylinders, but can also be mechanisms and components that realize linear displacement such as four-bar mechanisms.

[0032] As a preferred embodiment, the inner side of the conical arc plate 21 has a slide rail that cooperates with the slide rail plate 223. The conical arc plate 21 and the slide rail plate 223 form a directional sliding pair. The outer arc surface of the conical arc plate 21 has a taper with a diameter gradually decreasing upwards.

[0033] As a preferred embodiment, the tension controller 3 includes a hoist drum 31 and a motor 32, and the hoist drum 31 is rotatably connected to the shaft of the motor 32. Figure 5 As shown, there is an inverted trapezoidal groove on the shaft of the motor 32, and the hoisting drum 31 includes a knob 311, a spring 312, a groove block 313, a cube 314 and a cylinder 315, as shown in FIG. Figure 6As shown, the cylinder 315 has an extended cylinder, the outer surface of the cylinder is marked with scales, and the cylinder has a hole reaching the center of the cylinder 315. The knob 311 is threadedly connected to the outer side of the cylinder extending from the cylinder 315. Rotating the knob 311 can compress and expand the space formed with the inside of the cylinder 315. One end of the spring 312 is connected to the bottom of the internal cavity of the knob 311, and the other end is connected to the groove block 313. The groove block 313 slides in the hole of the cylinder. When the internal space is compressed, the spring 312 provides greater pressure to the groove block 313. When the internal space is expanded, the spring 312 reduces the pressure on the groove block 313. The groove block 313 has a trapezoidal groove that is opposite to the axis. The trapezoidal groove on the groove block 313 has the same specifications as the trapezoidal groove on the axis. The cube 314 is tightly installed In the cavity formed by the shaft and the wedge-shaped groove block 313, when the shaft of the motor 32 rotates, the groove block 313 provides pressure to the cube 314, forcing the winch drum 31 to rotate with the shaft, thereby tightening the tension rope 5 and providing tension to the buckle assembly 4. When the tension reaches a limited value, the counter pressure of the cube 314 on the groove block 313 exceeds the elastic force of the spring 312, the cube 314 flips over in the cavity, and the winch drum 31 rotates on the shaft. Due to the limitation of the trapezoidal groove edge, the winch drum 31 only rotates a small amount on the shaft and is stuck by the cube 314. The winch drum 31 is fixed relative to the shaft again. At this time, the motor 32 senses the jamming at the output end, stops rotating and locks immediately, thereby achieving the purpose of providing a fixed tension to the buckle assembly 4.

[0034] As a preferred embodiment, the method in which the tension controller 3 provides the fixed tension to the buckle assembly 4 is not limited to relying on the cooperation between the spring 312 and the cube 314, but may also be a method in which a hydraulic rod or the like provides the fixed tension.

[0035] As a preferred embodiment, the buckle assembly 4 includes a buckle ring 41, a connecting rod 42 and a pressing plate 43. Figure 7 As shown, one end of four connecting rods 42 is hinged on the buckle 41, and the other end is hinged on the connecting seats of two pressure plates 43 in groups of two. When the lower end of the buckle 41 is subjected to tension, the two pressure plates 43 will be forced to press against the flanges on both sides of the foot buckle climbing board 6.

[0036] The working principle of the present invention is as follows: before conducting experiments, the foot-buckle climbing board 6 is adjusted according to the use requirements, the nut on the threaded rod 2231 is adjusted to control the initial diameter of the variable diameter simulation pile 2, the two foot-buckle climbing boards 6 are hung on the variable diameter simulation pile 2, the buckle assembly 4 is pressed tightly on the foot pedal of the foot-buckle climbing board 6, the knob 311 is adjusted to the required tension position according to the scale, the motor 32 is started, and after the required tension is reached, the motor 32 is locked, all telescopic rods I221 are extended or shortened to simulate the change of rod diameter, and at the same time all lifting and retracting rods II231 adjust the angles of the two conical arc plates 21 to simulate the foot-buckle climbing board 6. After all diameters meet the requirements, the motor 32, the telescopic rod I221 and the lifting and retracting rod II231 are reset, the knob 311 is adjusted to the tension required for the next experiment, and the above process is repeated until all tension and diameter series experiments are completed.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
