Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, in particular to a boom deflection detection device, a transfer hoist and transfer equipment. Background Art

[0002] In the structure of the transfer equipment, the boom of the transfer equipment is an important load-bearing component that affects the overall lifting performance, working stability and safety of the transfer equipment. When the transfer equipment is lifting heavy objects, the boom of the transfer equipment will undergo a certain degree of deflection and deformation, and the end of the boom of the transfer equipment will undergo a certain degree of displacement. If the displacement is too large, it may cause an accident or even cause catastrophic consequences. In order to avoid excessive deflection during the operation of the transfer equipment and hinder normal operation, it is necessary to measure and display the deflection of the transfer equipment in real time and control it within a certain range. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the present application proposes a boom deflection detection device, a transfer hoist and a transfer equipment, which can measure the deflection of the transfer equipment in real time when the transfer equipment is operating.

[0004] On the one hand, the utility model provides a boom deflection detection device, which includes two rotating shafts, and the two rotating shafts can rotate in the horizontal direction respectively. The transfer slings installed on the transfer equipment are located on both sides of the lifting wire rope. Rocking arms are provided on the two rotating shafts, and a contact rod is spanned between the two rocking arms. Torsion springs are sleeved on the two rotating shafts, and the torsion springs can drive the rotating shafts to rotate so that the contact rod is always in contact with the lifting wire rope. A rotary encoder is installed on at least one of the rotating shafts through a coupling, and the rotary encoder can monitor the rotation angle of the rotating shaft in real time.

[0005] As a further improvement of the above technical solution:

[0006] The above-mentioned boom deflection detection device, further, the abutment rod includes a connecting rod and a roller rotatably mounted on the connecting rod, the connecting rod is spanned between the two rocker arms, and the roller can roll and abut against the lifting wire rope.

[0007] The above-mentioned boom deflection detection device further includes a mounting seat, which can be fixedly mounted on the transfer hanger of the transfer equipment, and a mounting hole is opened on the mounting seat. The rotary encoder is installed on the rotating shaft through a coupling, and the coupling can be rotatably installed in the mounting hole.

[0008] Another aspect of the utility model provides a transfer sling, which comprises the boom deflection detection device as described above.

[0010] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the utility model can be achieved.

[0011] The utility model provides a boom deflection detection device, transfer sling and transfer equipment, which, compared with the prior art, have at least the following beneficial effects: when the boom of the transfer equipment lifts a heavy object and generates deflection, the transfer sling installed on the boom and the hoisted object generate relative displacement to cause the lifting wire rope to deflect, and because the torsion spring can drive the rotating shaft to rotate so that the abutment rod is always in abutment with the lifting wire rope, the rotary encoder will be driven through the coupling to generate an angle change, and then the deflection change of the boom can be obtained through data conversion.

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] The embodiment of the utility model provides a boom deflection detection device 100, which can measure the deflection of the transfer equipment in real time when the transfer equipment is in operation.

[0026] See also Figure 1 The boom deflection detection device 100 provided by the embodiment of the utility model includes two rotating shafts 110, and the two rotating shafts 110 can rotate in the horizontal direction respectively. The transfer slings installed on the transfer equipment are located on both sides of the lifting wire rope 200. Rockers 120 are provided on the two rotating shafts 110, and a contact rod 130 is spanned between the two rockers 120. Torsion springs 140 are sleeved on the two rotating shafts 110. The torsion springs 140 can drive the rotating shafts 110 to rotate so that the contact rod 130 is always in contact with the lifting wire rope 200. A rotary encoder 160 is installed on at least one rotating shaft 110 through a coupling 150, and the rotary encoder 160 can monitor the rotation angle of the rotating shaft 110 in real time.

[0027] When the boom of the transfer equipment lifts a heavy object and generates deflection, the transfer sling installed on the boom and the load generate relative displacement, causing the lifting wire rope 200 to deflect. Since the torsion spring 140 can drive the rotating shaft 110 to rotate so that the abutment rod 130 is always in abutment with the lifting wire rope 200, the rotary encoder 160 will be driven to generate an angle change through the coupling 150, and then the deflection change of the boom is obtained through data conversion.

[0028] The boom deflection detection device 100 provided in the embodiment of the utility model further refers to Figure 1 The abutment rod 130 includes a connecting rod 131 and a roller 132 rotatably mounted on the connecting rod 131. The connecting rod 131 is arranged between the two rocker arms 120, and the roller 132 can roll and abut against the lifting wire rope 200. When the lifting wire rope 200 rises or falls, the roller 132 rotates relative to the connecting rod 131, thereby reducing the wear of the lifting wire rope 200.

[0029] The boom deflection detection device 100 provided in the embodiment of the utility model further refers to Figure 1The boom deflection detection device 100 further includes a mounting seat 170, which can be fixedly mounted on the transfer sling of the transfer equipment. A mounting hole is provided on the mounting seat 170, and a rotary encoder 160 is mounted on the rotating shaft 110 through a coupling 150, and the coupling 150 can be rotatably mounted in the mounting hole. Since the rotary encoder 160 is mounted on the end of the rotating shaft 110 through the coupling 150, in order to prevent the gravity of the rotary encoder 160 from affecting the rotation of the rotating shaft 110, the mounting seat 170 is provided, and the coupling 150 can be rotatably mounted in the mounting hole of the mounting seat 170, so as to prevent the gravity of the rotary encoder 160 from affecting the rotation of the rotating shaft 110.
