[0036] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0037] It should be understood that terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0038] As Figure 1 shown, the present invention provides a hoisting device for precast capping beams, including: a hoisting connection mechanism 1, which is connected to a hanger through a plurality of first lifting ropes 3, and a plurality of second lifting ropes 4 for hoisting a precast capping beam 2 are provided on the hoisting connection mechanism 1; a detection mechanism 5 provided on the hoisting connection mechanism 1, the detection mechanism 5 is used for detecting hoisting stability; a control module, which is used for correspondingly adjusting the hoisting speed of the hanger according to the detected result of hoisting stability.

[0039] The hanging bracket can control the hoisting connection mechanism 1 to move vertically and horizontally. The vertical movement is achieved by changing the lengths of a plurality of first suspension ropes 3. The hoisting connection mechanism 1 can be connected to the precast capping beam 2 through a plurality of second suspension ropes 4. During the entire hoisting process, the detection mechanism 5 can detect whether the hoisting process is stable and adjust the hoisting speed of the hanging bracket in a timely manner. For example, when the precast capping beam 2 being hoisted sways due to environmental factors or other factors, it will cause the hoisting connection mechanism 1 to sway. At this time, if the hoisting speed is too high, the sway of the precast capping beam 2 will be aggravated, and the hoisting stability is poor, affecting the positioning accuracy of the precast capping beam 2. Therefore, the detection mechanism 5 can detect the result of the hoisting stability in real time to control the hoisting process and improve the hoisting stability and positioning accuracy of the precast capping beam 2.

[0040] The hoisting connection mechanism 1 can connect the precast capping beam 2 and the hanging bracket. By detecting the hoisting connection mechanism 1 through the detection mechanism 5, the hoisting process of the precast capping beam 2 can be indirectly detected in real time, and the hoisting process can be controlled in a timely manner through the control module to make corresponding adjustments, so as to improve the hoisting stability and positioning accuracy of the precast capping beam 2, reduce the installation error, and ensure the installation accuracy.

[0041] In one embodiment, the control module includes:

[0042] A first acquisition unit, configured to acquire the result of the hoisting stability detected by the detection mechanism 5 when the hoisting connection mechanism 1 hoists the precast capping beam 2;

[0043] A first control unit, configured to adjust the hoisting speed of the hanging bracket according to the result of the hoisting stability acquired by the first acquisition unit, so that the hoisting stability meets the first standard.

[0044] Wherein, the result of the hoisting stability includes: the hoisting stability meets the first standard and the hoisting stability does not meet the first standard.

[0045] When the hoisting stability meets the first standard, there is no need to adjust the hoisting speed; when the hoisting stability does not meet the first standard, it is necessary to adjust the hoisting speed. For example: when the hanging bracket starts hoisting, it hoists at a set speed. When it is necessary to adjust the hoisting speed, the hoisting speed needs to be slowed down to reduce the sway of the precast capping beam 2.

[0046] Through the above design, the detection mechanism 5 can detect the sway degree of the precast capping beam 2 during the hoisting process to ensure the hoisting stability of the precast capping beam 2 and improve the hoisting safety and positioning accuracy.

[0047] In one embodiment, the control module further includes:

[0048] A second acquisition unit, configured to acquire the hoisting level detected by the detection mechanism 5 before the hoisting connection mechanism 1 hoists the precast capping beam 2 and before the precast capping beam 2 reaches the designated installation position;

[0049] A second control unit, configured to adjust the lengths of the plurality of first suspension ropes 3 according to the hoisting level acquired by the second acquisition unit, so that the hoisting level meets the second standard.

[0050] Wherein, when the hoisting level meets the second standard, there is no need to adjust the lengths of the plurality of first suspension ropes 3; when the hoisting level does not meet the second standard, the lengths of the plurality of first suspension ropes 3 need to be adjusted.

[0051] Furthermore, the length of the second suspension rope 4 is a fixed length.

[0052] In this embodiment, the detection mechanism 5 can also perform detections in two stages: before the hoisting connection mechanism 1 hoists the precast capping beam 2 and before the precast capping beam 2 reaches the designated installation position; since during hoisting, the lengths of the plurality of first suspension ropes 3 need to be changed during the hoisting process, and when changing the lengths, it is easy to have an error in the length change of the plurality of first suspension ropes 3, resulting in a situation where the hoisting connection mechanism 1 is offset relative to the horizontal plane, that is, the hoisting level does not meet the second standard, and at this time, adjustment is required;

[0053] Wherein, before the hoisting connection mechanism 1 hoists the precast capping beam 2, the hanger controls the hoisting connection mechanism 1 to move above the precast capping beam 2, and then the second acquisition unit acquires the hoisting level detected by the detection mechanism 5. At this time, mainly the hoisting level of the hoisting connection mechanism 1 is detected. If the hoisting level does not meet the second standard, the plurality of first suspension ropes 3 need to be adjusted so that the hoisting level meets the second standard. In this way, since the lengths of the plurality of second suspension ropes 4 are fixed, therefore, when the hoisting level of the hoisting connection mechanism 1 meets the second standard, the levelness of the precast capping beam 2 during hoisting can be ensured, preventing the precast capping beam 2 from tilting during hoisting and ensuring the safety of hoisting;

[0054] Of course, after the precast capping beam 2 is hoisted, the hoisting level can also be detected in real time through the second acquisition unit, and the length of the first suspension rope 3 can be adjusted in time through the second control unit; in addition, the priority of the second control unit is lower than that of the first control unit, that is, when obtaining the results of hoisting stability and hoisting level through the detection mechanism 5, the first control unit executes first. When the hoisting stability still does not meet the first standard after adjusting the hoisting speed of the hanger, the second control unit then executes to improve the stability during hoisting;

[0055] Before the precast capping beam 2 being hoisted reaches the designated installation position, that is, when the precast capping beam 2 is above the designated installation position, the hoisting levelness detected by the detection mechanism 5 is obtained through the second acquisition unit. At this time, the hoisting levelness of the precast capping beam 2 is mainly detected. Then, when the hoisting levelness does not meet the second standard, the second control unit adjusts the plurality of first lifting ropes 3 so that the precast capping beam 2 can be positioned when the hoisting levelness meets the second standard, thereby improving the positioning accuracy; then, after the precast capping beam 2 is positioned, during the process of moving downward to the designated installation position, the result of the hoisting stability also needs to be obtained through the first acquisition unit to ensure that the hoisting stability during the downward movement of the precast capping beam 2 meets the first standard, so as to reduce the installation error.

[0056] Through the above design, the smoothness and safety of the precast capping beam 2 during hoisting can be ensured, the accuracy during positioning can be improved, the installation error can be reduced, and the installation accuracy of the precast capping beam 2 can be improved.

[0057] As Figure 2 shown, in one embodiment, the detection mechanism 5 includes: a housing 51, an insulating area for the sphere 52 to move is formed inside it, a first conductive component 53 that is always in contact with the sphere 52 is provided at the top of the insulating area, and a second conductive component 54 that is in contact with the sphere 52 is provided at the bottom of the insulating area;

[0058] When the sphere 52 is in contact with the first conductive component 53 and the second conductive component 54, the hoisting stability detected by the detection mechanism 5 meets the first standard, or the hoisting levelness detected meets the second standard;

[0059] When the sphere 52 is not in contact with the second conductive component 54, the hoisting stability detected by the detection mechanism 5 does not meet the first standard, or the hoisting levelness detected does not meet the second standard.

[0060] When the sphere 52 is in contact with the first conductive component 53 and the second conductive component 54, the circuit where the sphere 52 is located is a closed circuit. When the sphere 52 is not in contact with the second conductive component 54, the circuit where the sphere 52 is located is an open circuit. The first acquisition unit and the second acquisition unit obtain the result of the hoisting stability and the hoisting levelness by acquiring the open or closed state of the circuit where the sphere 52 is located;

[0061] During the hoisting process, if the sphere 52 is shaken by less than the set amplitude (in the case where the hoisting connection mechanism 1 shakes), the sphere 52 will remain in contact with the first conductive component 53 and the second conductive component 54, indicating that the hoisting stability meets the first standard;

[0062] If the sphere 52 is shaken beyond a set amplitude (in the case of the lifting connection mechanism 1 being shaken), the sphere 52 will be in a non-contact state with the second conductive component 54, indicating that the lifting stability does not meet the first standard;

[0063] If the inclination degree of the sphere 52 is lower than the set degree (in the case of the lifting connection mechanism 1 being inclined), the sphere 52 will remain in contact with the first conductive component 53 and the second conductive component 54, indicating that the lifting level meets the second standard;

[0064] If the inclination degree of the sphere 52 exceeds the set degree (in the case of the lifting connection mechanism 1 being inclined), the sphere 52 will tilt to one side within the insulating region and be in a non-contact state with the second conductive component 54, indicating that the lifting level does not meet the second standard.

[0065] As Figures 2 - 4 shown, further, a first limit block 55 and a second limit block 56 are respectively provided at the top and bottom inside the housing 51, and both the first limit block 55 and the second limit block 56 are made of insulating materials; a first insulating groove 551 is formed at the bottom of the first limit block 55, a second insulating groove 561 is formed at the top of the second limit block 56, and an insulating region is formed between the first insulating groove 551 and the second insulating groove 561; the first insulating groove 551 and the second insulating groove 561 can limit the movement of the sphere 52, keeping the sphere 52 in a non-contact state with the housing 51;

[0066] The first conductive component 53 is disposed in the first insulating groove 551;

[0067] The inner side surface of one end of the first insulating groove 551 close to the sphere 52 is a conical surface, and the inner side surface of the second insulating groove 561 is also a conical surface. The bottom surface of the second insulating groove 561 is an inclined surface that gradually rises from the center to the outside. A first through hole 562 is provided at the center of the bottom surface of the second insulating groove 561, and the contact point of the second conductive component 54 passes through the first through hole 562 and contacts the sphere 52.

[0068] In the above solution, the housing 51 and the sphere 52 are made of conductive materials. The first conductive component 53 is insulated from the housing 51, and the second conductive component 54 is connected to the housing 51 to achieve contact conduction. The sphere 52 moves between the first limit block 55 and the second limit block 56 made of insulating materials, and through the limitation of the first insulating groove 551 and the second insulating groove 561, it can prevent the sphere 52 from contacting and conducting with the housing 51;

[0069] The center of the bottom surface of the second insulating groove 561 is the lowest point. When the detection mechanism 5 does not tilt or shake, the sphere 52 will always contact the contact point of the second conductive component 54 under the action of its own gravity. When the hoisting connection mechanism 1 where the detection mechanism 5 is located shakes or tilts, causing the sphere 52 to overcome gravity, the resistance of the bottom surface of the second insulating groove 561, and the resistance of contacting the first conductive component 53, the sphere 52 will separate from the contact point of the second conductive component 54 and be in a non-contact state. That is, the set amplitude set according to the shaking situation and the set degree set according to the tilt are related to the movement of the sphere 52 overcoming all resistances. Adjusting the set amplitude or set degree can be achieved by adjusting the gravity of the sphere 52, the inclination of the bottom surface of the second insulating groove 561, and the abutting force against the first conductive component 53.

[0070] As Figure 2 shown, further, the housing 51 includes: a housing body 511 and a cover body 512, and an insulating block 513 is provided in the middle of the cover body 512; wherein, both the cover body 512 and the housing body 511 are made of conductive materials;

[0071] The first conductive component 53 includes: a lead-out portion 531 penetrating through the first limiting block 55 and the insulating block 513, and an abutting portion 532 that always contacts the sphere 52 is provided at the end of the lead-out portion 531 located in the first insulating groove 551;

[0072] The second conductive component 54 includes: an elastic portion 541 provided below the second limiting block 56, one end of the elastic portion 541 is connected to the housing body 511, and the other end is provided with a contact portion 542 that contacts the sphere 52. The contact portion 542 passes through the first through hole 562 from bottom to top, and the contact point is located at the top of the contact portion 542.

[0073] The lead-out portion 531 is insulated from the cover body 512 through the insulating block 513. An electrical connection terminal can also be provided on the cover body 512, and then the circuit is connected through the end of the lead-out portion 531 extending to the outside of the housing 51 and the electrical connection terminal on the cover body 512;

[0074] To prevent the sphere 52 from separating from the contact portion 542 due to a small shake, the contact portion 542 is connected to the housing body 511 through the elastic portion 541. In this way, when a small shake or tilt occurs, the sphere 52 has a small position offset. At this time, the contact portion 542 will move upward a set distance under the elastic restoring force of the elastic portion 541, so as to contact the offset sphere 52. Of course, when the position of the sphere 52 has a large offset, the set distance that the contact portion 542 moves upward is not enough for it to still contact the sphere 52.

[0075] As Figure 5As shown, in one embodiment, the abutting portion 532 includes: a plurality of elastic sheets 533 arrayed circumferentially. An end of the lead-out portion 531 located in the first insulating groove 551 is provided with a connection block 534. One end of the elastic sheet 533 is connected to the connection block 534, and the inner side of the other end abuts against the surface of the sphere 52.

[0076] The plurality of elastic sheets 533 form a cone, covering the upper part of the sphere 52 therein. In this way, when the sphere 52 shakes or deflects in any direction, it will always maintain contact with the abutting portion 532. Therefore, the sphere 52 will always be in contact conduction with the first conductive component 53; the part of the elastic sheet 533 connected to the top surface of the connection block 534 and the part in contact with the sphere 52 form a substantially L shape, and the connection between the two is smoothly connected, improving the service life of the elastic sheet 533.

[0077] As Figure 6 shown, in one embodiment, the elastic portion 541 includes: a spiral elastic body 543, one end of which is connected to the contact portion 542 through a first plate body 544, and the other end is provided with a second plate body 545. On a side of the second plate body 545 away from the center of the spiral elastic body 543, a third plate body 546 extends upward. The third plate body 546 is located between the outside of the second limiting block 56 and the inside of the housing 511, and the third plate body 546 contacts the housing 511.

[0078] As Figure 7 shown, further, the bottom of the second limiting block 56 is provided with a plurality of support columns 563, and the third plate body 546 is provided with a second through hole 547 sleeved with one of the support columns 563.

[0079] To facilitate the setting of the elastic portion 541 and design its elastic ability, the spiral elastic body 543 provides elastic support for the contact portion 542. The first plate body 544, the second plate body 545, and the third plate body 546 can all be made of rigid materials; among them, the second plate body 545 is fixedly connected to the support column 563 through the second through hole 547, and the third plate body 546 is clamped between the second limiting block 56 and the housing 511, which can ensure that the third plate body 546 is always in a conductive state with the housing 511; thus, the end of the spiral elastic body 543 connected to the second plate body 545 is a fixed end, and the end connected to the first plate body 544 is a free end. When the contact portion 542 moves up and down, the spiral elastic body 543 can provide elastic support ability.
