DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] like Figure 1 As shown, the present invention provides a hoisting device for prefabricated cap beams, comprising: a hoisting connection mechanism 1, which is connected to a hanger through a plurality of first hoisting ropes 3, and the hoisting connection mechanism 1 is provided with a plurality of second hoisting ropes 4 for hoisting the prefabricated cap beam 2; a detection mechanism 5 arranged on the hoisting connection mechanism 1, and the detection mechanism 5 is used to detect hoisting stability; a control module, which is used to adjust the hoisting speed of the hanger according to the result of the detected hoisting stability.

[0021] The hanger can control the lifting connection mechanism 1 to move vertically and horizontally, and the vertical movement is achieved by changing the length of multiple first lifting ropes 3; the lifting connection mechanism 1 can be connected to the prefabricated cap beam 2 through multiple second lifting ropes 4; in the whole lifting process, the detection mechanism 5 can detect whether the lifting process is stable, and timely adjust the lifting speed of the hanger; for example, when the lifted prefabricated cap beam 2 shakes due to environmental factors or other factors, it will cause the lifting connection mechanism 1 to shake. At this time, if the lifting speed is too high, the shaking of the prefabricated cap beam 2 will be aggravated, and the lifting stability will be poor, affecting the positioning accuracy of the prefabricated cap beam 2. Therefore, the detection mechanism 5 can detect the lifting stability in real time to realize the control of the lifting process and improve the lifting stability and positioning accuracy of the prefabricated cap beam 2.

[0022] The prefabricated cap beam 2 and the hanger can be connected through the lifting connection mechanism 1. Through the detection of the lifting connection mechanism 1 by the detection mechanism 5, the lifting process of the prefabricated cap beam 2 can be indirectly detected in real time, and the lifting process can be timely controlled through the control module to make corresponding adjustments, so as to improve the lifting stability and positioning accuracy of the prefabricated cap beam 2, reduce installation errors and ensure installation accuracy.

[0023] In one embodiment, the control module comprises: The first acquisition unit is used to obtain the result of the hoisting stability detected by the detection mechanism 5 when the hoisting connection mechanism 1 hoists the prefabricated cap beam 2; The first control unit is used to adjust the hoisting speed of the hanger according to the result of the hoisting stability obtained by the first obtaining unit, so that the hoisting stability meets the first standard.

[0024] The results of the hoisting stability include: the hoisting stability meets the first standard and the hoisting stability does not meet the first standard.

[0025] 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, the hoisting speed needs to be adjusted; for example: when the hanger starts hoisting, it is hoisted at the set speed. When the hoisting speed needs to be adjusted, it is necessary to slow down the hoisting speed to reduce the shaking of the prefabricated cap beam 2.

[0026] Through the above design, the shaking degree of the prefabricated cap beam 2 during the lifting process can be detected by the detection mechanism 5 to ensure the lifting stability of the prefabricated cap beam 2 and improve the lifting safety and positioning accuracy.

[0027] In one embodiment, the control module further includes: The second acquisition unit is used to acquire the hoisting level detected by the detection mechanism 5 before the hoisting connection mechanism 1 lifts the prefabricated cap beam 2 and before the prefabricated cap beam 2 reaches the designated installation position; The second control unit is used to adjust the lengths of the plurality of first hoisting ropes 3 according to the hoisting level obtained by the second obtaining unit, so that the hoisting level meets the second standard.

[0028] When the hoisting level meets the second standard, there is no need to adjust the lengths of the multiple first hoisting ropes 3 ; when the hoisting level does not meet the second standard, it is necessary to adjust the lengths of the multiple first hoisting ropes 3 .

[0029] Furthermore, the length of the second suspension rope 4 is fixed.

[0030] In this embodiment, the detection mechanism 5 can also perform detection at two stages, before the hoisting connection mechanism 1 lifts the prefabricated cap beam 2 and before the prefabricated cap beam 2 reaches the designated installation position; because during hoisting, the lengths of the plurality of first hoisting ropes 3 need to be changed during the hoisting process, and when the lengths are changed, it is easy for the length changes of the plurality of first hoisting ropes 3 to have errors, resulting in the hoisting connection mechanism 1 being offset relative to the horizontal plane, that is, the hoisting level does not meet the second standard, and adjustment is required at this time; Among them, before the lifting connection mechanism 1 lifts the prefabricated cap beam 2, the hanger controls the lifting connection mechanism 1 to move above the prefabricated cap beam 2, and then obtains the lifting level detected by the detection mechanism 5 through the second acquisition unit. At this time, the lifting level of the lifting connection mechanism 1 is mainly detected. If the lifting level does not meet the second standard, it is necessary to adjust the multiple first lifting ropes 3 to make the lifting level meet the second standard. In this way, since the lengths of the multiple second lifting ropes 4 are fixed, when the lifting level of the lifting connection mechanism 1 meets the second standard, the level of the prefabricated cap beam 2 can be guaranteed when lifting, and the prefabricated cap beam 2 can be prevented from being skewed during lifting, thereby ensuring the safety of lifting; Of course, after the prefabricated cap beam 2 is lifted, the lifting level can also be detected in real time through the second acquisition unit, and the length of the first lifting 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 the lifting stability result and the lifting level are obtained through the detection mechanism 5, the first control unit is executed first, and after adjusting the lifting speed of the hanger, when the lifting stability still does not meet the first standard, it is executed by the second control unit to improve the stability during lifting; Before the hoisted prefabricated cap beam 2 reaches the designated installation position, that is, when the prefabricated cap beam 2 is located above the designated installation position, the hoisting level detected by the detection mechanism 5 is acquired by the second acquisition unit. At this time, the hoisting level of the prefabricated cap beam 2 is mainly detected, and then when the hoisting level does not meet the second standard, the second control unit is used to adjust the multiple first hoisting ropes 3 so that the prefabricated cap beam 2 can be positioned when the hoisting level meets the second standard, so as to improve the positioning accuracy; then, after the prefabricated cap beam 2 is positioned, it starts to move downward to the designated installation position, and the first acquisition unit is also required to obtain the result of the hoisting stability to ensure that the hoisting stability of the prefabricated cap beam 2 during the downward movement meets the first standard to reduce the installation error.

[0031] Through the above design, the stability and safety of the prefabricated cap beam 2 during lifting can be guaranteed, the accuracy of positioning can be improved, and the installation error can be reduced, thereby improving the installation accuracy of the prefabricated cap beam 2.

[0032] like Figure 2 As shown, in one embodiment, the detection mechanism 5 includes: a housing 51, an insulating area for the ball 52 to move is formed inside the housing, a first conductive component 53 that is always in contact with the ball 52 is provided on the top of the insulating area, and a second conductive component 54 that is in contact with the ball 52 is provided on the bottom of the insulating area; When the ball 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; When the sphere 52 and the second conductive component 54 are in a non-contact state, 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.

[0033] When the ball 52 is in contact with the first conductive component 53 and the second conductive component 54, the circuit where the ball 52 is located is open; when the ball 52 is in non-contact with the second conductive component 54, the circuit where the ball 52 is located is open. The first acquisition unit and the second acquisition unit obtain the state of the circuit where the ball 52 is located, and obtain the result of the hoisting stability and the hoisting levelness; During the hoisting process, if the ball 52 is shaken below the set amplitude (the hoisting connection mechanism 1 shakes), the ball 52 will maintain contact with the first conductive component 53 and the second conductive component 54, indicating that the hoisting stability meets the first standard; If the ball 52 is shaken beyond the set amplitude (when the hoisting connection mechanism 1 shakes), the ball 52 will be in a non-contact state with the second conductive component 54, indicating that the hoisting stability does not meet the first standard; If the inclination of the ball 52 is lower than the set degree (the hoisting connection mechanism 1 is tilted), the ball 52 will maintain contact with the first conductive component 53 and the second conductive component 54, indicating that the hoisting level meets the second standard; If the tilt of the sphere 52 exceeds the set degree (the hoisting connection mechanism 1 is tilted), the sphere 52 will tilt to one side in the insulating area and be in a non-contact state with the second conductive component 54, indicating that the hoisting level does not meet the second standard.

[0034] like Figure 2-Figure 4 As shown, further, a first limit block 55 and a second limit block 56 are respectively provided at the top and the bottom of the shell 51, and the first limit block 55 and the second limit block 56 are both made of insulating materials; a first insulating groove 551 is formed at the bottom of the first limit block 55, and a second insulating groove 561 is formed at the top of the second limit block 56, and an insulating area 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 ball 52, so that the ball 52 and the shell 51 remain in a non-contact state; The first conductive component 53 is disposed in the first insulating slot 551; The inner side surface of one end of the first insulating groove 551 close to the sphere 52 is a conical surface, 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, and a first through hole 562 is provided at the center of the bottom surface of the second insulating groove 561. The contact point of the second conductive component 54 contacts the sphere 52 after passing through the first through hole 562.

[0035] In the above scheme, the housing 51 and the sphere 52 are made of conductive materials, the first conductive component 53 is insulated from the housing 51, the second conductive component 54 is connected to the housing 51 to achieve contact and conduction, the sphere 52 moves between the first limit block 55 and the second limit block 56 made of insulating material, and is restricted by the first insulating groove 551 and the second insulating groove 561 to prevent the sphere 52 from contacting and conducting with the housing 51; 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 be in contact with the contact point of the second conductive component 54 under the action of its own gravity; when the lifting connection mechanism 1 where the detection mechanism 5 is located shakes or tilts and the sphere 52 overcomes the gravity, the resistance of the bottom surface of the second insulating groove 561 and the resistance of contact with the first conductive component 53, the sphere 52 will be separated 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 activity generated by the sphere 52 overcoming all resistances. Adjustment of the set amplitude or the set degree can be achieved by adjusting the gravity of the sphere 52, the tilt of the bottom surface of the second insulating groove 561 and the abutment force with the first conductive component 53.

[0036] like Figure 2 As shown, further, the housing 51 includes: a shell 511 and a cover 512, and an insulating block 513 is provided in the middle of the cover 512; wherein the cover 512 and the shell 511 are both made of conductive materials; The first conductive component 53 includes: a lead-out portion 531 penetrating the first limiting block 55 and the insulating block 513, and an end of the lead-out portion 531 located in the first insulating groove 551 is provided with an abutment portion 532 that is always in contact with the ball 52; The second conductive component 54 includes: an elastic portion 541 arranged below the second limit block 56, one end of the elastic portion 541 is connected to the shell 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.

[0037] The lead-out portion 531 is insulated from the cover 512 by the insulating block 513. The cover 512 may also be provided with an electrical connection terminal, and 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 512; In order to prevent the ball 52 from losing contact with the contact part 542 due to a small shake, the contact part 542 is connected to the shell 511 through the elastic part 541. In this way, when a small shake or tilt occurs, the ball 52 will have a small position deviation. At this time, the contact part 542 will move upward a set distance under the elastic recovery force of the elastic part 541, so as to contact the deviated ball 52. Of course, when the position of the ball 52 is greatly deviated, the set distance that the contact part 542 moves upward is not enough to keep it in contact with the ball 52.

[0038] like Figure 5 As shown, in one embodiment, the abutment portion 532 includes: a plurality of elastic sheets 533 arranged in a circumferential direction, a connecting block 534 is provided at the end of the lead-out portion 531 in the first insulating groove 551, one end of the elastic sheet 533 is connected to the connecting block 534, and the inner side surface of the other end abuts against the surface of the sphere 52.

[0039] A plurality of elastic sheets 533 form a cone, and the upper part of the sphere 52 is covered therein, so that when the sphere 52 shakes or deflects in any direction, it will maintain contact with the abutment portion 532. Therefore, the sphere 52 will always be in contact and conductive with the first conductive component 53. The portion of the elastic sheet 533 connected to the top surface of the connecting block 534 and the portion in contact with the sphere 52 form a roughly L-shape, and the connection between the two is a smooth connection, thereby improving the service life of the elastic sheet 533.

[0040] like Figure 6 As 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, and the second plate body 545 extends upward on a side away from the center of the spiral elastic body 543 and is provided with a third plate body 546, and the third plate body 546 is located between the outer side of the second limit block 56 and the inner side of the shell 511, and the third plate body 546 is in contact with the shell 511.

[0041] like Figure 7 As shown, further, a plurality of support columns 563 are provided at the bottom of the second limiting block 56 , and a second through hole 547 which is sleeved with one of the support columns 563 is provided on the third plate body 546 .

[0042] In order to facilitate the setting of the elastic part 541 and the design of its elastic capacity, the spiral elastic body 543 is used to provide elastic support for the contact part 542, and the first plate 544, the second plate 545 and the third plate 546 can all be made of rigid materials; wherein, the second plate 545 is fixedly connected to the support column 563 through the second through hole 547, and the third plate 546 is clamped between the second limit block 56 and the shell 511, which can ensure that the third plate 546 is always in a conductive state with the shell 511; in this way, the end of the spiral elastic body 543 connected to the second plate 545 is a fixed end, and the end connected to the first plate 544 is a free end, when the contact part 542 moves up and down, it can provide elastic support capacity through the spiral elastic body 543.
