Description

Technical Field

[0001] The utility model relates to the technical field of crane testing devices, in particular to a crane hoisting object travel sensing device. Background Art

[0002] The original practical operation skill test for crane drivers mainly adopts the traditional manual scoring and manual recording methods. The scoring mainly depends on the intuitive records and subjective judgments of the examiners, which inevitably introduces some subjective factors and affects the objectivity of the scoring. For example, the examiners need to observe from multiple angles at the same time to accurately determine the route of the hoisted object, but it is actually difficult to achieve. The examiners' distracted attention and rough estimation of the height may also affect the objectivity of the scoring. Therefore, the use of an intelligent automatic scoring system can fundamentally eliminate the influence of subjective factors of personnel and further improve the objectivity and fairness of the examination process. In addition, it can also prevent personnel from deliberately destroying the fairness of the examination.

[0003] For example, a Chinese authorized patent with a publication number of CN219455121U is a crane hoist movement sensing device, wherein the crane hoist moves along a preset travel path, and the device comprises a hoist, a first detection component and a second detection component, wherein the first detection component and the second detection component are arranged on both sides of the travel path; the first detection component and the second detection component are both sensor detection structures, wherein the sensor detection structure comprises a first column, a second column and a sensor, wherein the first column is arranged at the starting position of the movement of the hoist, and the second column is arranged at the end position of the movement of the hoist, and the sensor comprises a signal transmitting end and a signal receiving end, wherein the signal transmitting end is fixed on the first column, and the signal receiving end is fixed on the second column.

[0004] The above-mentioned traditional sensing device is used for detection by setting up a signal transmitting end and a signal receiving end. However, if the surface of the sensor is stained with dust or debris, it will affect the detection result. When the hoisted object does not pass through the sensor, it will still be a problem of false detection, which affects the perception result of the crane hoisting the object and causes the perception effect to be not sensitive enough.

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.

[0027] Example

[0028] Reference Figure 1-5As shown, a crane hoisting object movement sensing device includes two oppositely arranged columns 1 and a signal transmitting end 2 and a signal receiving end 3 installed on opposite sides of the two columns 1. A cleaning mechanism is arranged on opposite sides of the two columns 1.

[0029] The cleaning mechanism includes a sliding block 514, a sliding groove 515, a movable plate 516, a cleaning layer 517 and a driving component. The sliding block 514 is fixed on the inner wall of the movable plate 516. The outer wall of the column 1 is provided with a vertically distributed sliding groove 515 that slides with the sliding block 514. The sliding block 514 can stably slide along the outer wall direction of the sliding groove 515. The inner wall of the movable plate 516 is provided with a cleaning layer 517 corresponding to the signal transmitting terminal 2 and the signal receiving terminal 3. The outer wall of the column 1 is provided with a driving component for driving the movable plate 516 to reciprocate vertically, so as to drive the cleaning layer 517 and the surfaces of the signal transmitting terminal 2 and the signal receiving terminal 3 to be cleaned.

[0030] The driving component includes a connecting plate 511, a screw rod 512 and a driving motor 513. The connecting plate 511 is provided with two groups and is fixed to the top and bottom of the column 1 respectively. The two groups of connecting plates 511 are connected to the screw rod 512 that is threadedly connected to the sliding block 514 when rotating relative to one side. The driving motor 513 is installed on the outer wall of any group of connecting plates 511 and the output end is connected to the screw rod 512. The driving motor 513 is turned on to drive the screw rod 512 to rotate forward or reverse. Under the action of the thread, the sliding block 514, the moving plate 516 and the cleaning layer 517 are driven to move vertically back and forth, and the surfaces of the signal transmitting end 2 and the signal receiving end 3 can be wiped and cleaned comprehensively. The width of the cleaning layer 517 is greater than the width of the signal transmitting end 2 and the signal receiving end 3. The cleaning layer 517 can fully cover the signal transmitting end 2 and the signal receiving end 3 to achieve a large-area cleaning effect. The cleaning layer 517 is made of sponge material. The sponge has a good cleaning effect and can have an adsorption effect to clean impurities or dust on the surface of the signal transmitting end 2 and the signal receiving end 3.

[0031] A hole 413 is provided at the bottom of the column 1, and a vertical column 411 is inserted into the hole 413. A base 412 is fixed to the bottom of the vertical column 411. The vertical column 411 is connected to the outer wall of the column 1 through a limit mechanism. The vertical column 411 can move up and down along the hole 413 to adjust the distance between the column 1 and the ground, so as to adjust the height of the column 1, and facilitate the detection and use of hanging objects at different heights. Four groups of mounting holes 414 are provided inside the base 412. The four groups of mounting holes 414 are distributed equidistantly around the axis of the vertical column 411. The mounting holes 414 are provided to facilitate fixing to the ground, so as to ensure that the column 1 is sufficiently stable when supporting. The limiting mechanism includes a fixing plate 415, a plug rod 416 and a slot 417. The fixing plate 415 is fixed to the bottom end of the column 1. The plug rod 416 runs through the fixing plate 415. The outer wall of the vertical column 411 is provided with a plurality of groups of slots 417 distributed vertically. The plug rod 416 is arranged corresponding to the slots 417. Pulling the baffle 418 drives the plug rod 416 to enter and exit the slots 417 at different heights, which can facilitate locking or adjusting the height of the column 1. A baffle 418 is fixed to the end of the plug rod 416 away from the slot 417. A spring 419 is wound around the outer wall of the plug rod 416. The baffle 418 and the fixing plate 415 are connected by the spring 419. The provision of the spring 419 has a good rebound effect, and the plug rod 416 can be stably inserted into the slot 417 under the rebound of the spring 419, making the connection more stable.

[0032] Working principle: When the surfaces of the signal transmitting end 2 and the signal receiving end 3 need to be cleaned, the driving motor 513 is turned on to drive the screw rod 512 to rotate, and the sliding block 514 is driven to slide downward along the inside of the sliding groove 515 under the action of the thread, thereby driving the moving plate 516 and the cleaning layer 517 to move downward. The cleaning layer 517 can clean the dust and debris on the surfaces of the signal transmitting end 2 and the signal receiving end 3 to ensure the accuracy of the detection effect.

[0033] When the height of the column 1 needs to be adjusted, the baffle 418 is pulled to drive the rod 416 to disengage from the slot 417, and the spring 419 is stretched. Then, the base 412 is pulled downward to drive the vertical column 411 to move downward, thereby increasing the height of the column 1, the signal transmitting end 2 and the signal receiving end 3 from the ground. At this time, the baffle 418 is released, and the rod 416 is driven to be inserted into another set of slots 417 under the elastic reset action of the spring 419, and the limit fixation is performed again.
