Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, specifically to a hoisting connection device and hoisting equipment. Background Technology
[0002] The air compressor system of the power center of the cigarette factory consists of various types of adsorption dryers. During the operation of the air compressor system, the adsorption dryers need to be maintained and repaired regularly.
[0003] During regular maintenance, the impeller inside the adsorption dryer needs to be cleaned or replaced. Lifting equipment is required to hoist the impeller during both disassembly and installation of the self-adsorption dryer.
[0004] However, the size of the impeller inside different models of adsorption dryers is different, and the positions of the two connecting parts of the impeller used for hoisting are different. Therefore, when hoisting the impeller, it is necessary to constantly change the hoisting connection device according to the size of the impeller, which increases the workload of impeller hoisting and reduces the efficiency of maintenance work. Utility Model Content
[0005] The purpose of this invention is to overcome the problem of having to frequently change the lifting connection device according to the size of the wheel during the wheel lifting process.
[0006] To achieve the above objectives, this utility model provides a hoisting connection device, which includes an adjustment mechanism, a fixing mechanism, and two connecting mechanisms. The adjustment mechanism includes a main rod and an adjusting tube. One end of the main rod extends into the cavity of the adjusting tube and can slide and be positioned therein to adjust the length of the adjustment mechanism. One connecting mechanism is located on the part of the main rod outside the adjusting tube, and the other connecting mechanism is located on the end of the adjusting tube opposite to the main rod. The two connecting mechanisms are respectively used for detachable connection with two connecting parts of the rotating wheel. The main rod and the adjusting tube are connected to the hoisting equipment through the fixing mechanism.
[0007] In some embodiments, the fixing mechanism includes a first crossbar, a first connector, and a second connector. The first crossbar is connected to a hoisting device. The main member is connected to the first crossbar via the first connector, and the adjusting pipe is connected to the first crossbar via the second connector to fix the position of the main member in the cavity of the adjusting pipe.
[0008] In some embodiments, both the first connector and the second connector are lifting bolts, and both the main rod and the adjusting tube are provided with vertically extending threaded holes. The distance between the first connector and the second connector in the length direction of the first crossbar is adjustable so that the two lifting bolts are threadedly connected to the two threaded holes in a one-to-one correspondence.
[0009] In some embodiments, the first crossbar has a vertically extending strip hole, the length direction of which is consistent with the length direction of the first crossbar; a first connector and a second connector are inserted into the strip hole, and the two can slide in the strip hole to adjust their distance, and can be fixedly connected to the first crossbar by a nut.
[0010] In some embodiments, an annular washer is provided between the nut and the first crossbar. In some embodiments, the first crossbar has a plurality of vertically penetrating through holes, and a lifting bolt protruding from the threaded hole can be fixedly connected to any of the through holes.
[0011] In some embodiments, the two through holes of the first crossbar, each with a lifting bolt, are equidistant from the center of the first crossbar along its length.
[0012] In some embodiments, the two connecting mechanisms are equidistant from the center of the adjusting mechanism along its length direction.
[0013] In some embodiments, the connecting mechanism is an eye bolt, which is threadedly connected to the connecting part of the wheel.
[0014] In another aspect, this utility model provides a hoisting device, which includes the hoisting connection device in the above embodiments.
[0015] The above-mentioned technical solution of this utility model has the following beneficial effects:
[0016] The end of the main rod extends into the internal cavity of the adjusting pipe and can reciprocate along the length of the cavity. Two connecting mechanisms are respectively connected to the outer ends of the main rod and the adjusting pipe. When the main rod moves towards the adjusting pipe, the length of the adjusting mechanism decreases, thereby reducing the distance between the two connecting mechanisms on both sides of the adjusting mechanism along its length. When the main rod moves away from the adjusting pipe, the length of the adjusting mechanism increases, thereby increasing the distance between the two connecting mechanisms on both sides of the adjusting mechanism along its length. Before hoisting the wheel, the length of the adjusting mechanism is adjusted to adjust the distance between the two connecting mechanisms, allowing each connecting mechanism to connect to the two connecting parts of the wheel. Therefore, the hoisting connection device of this invention can adjust the distance between the two connecting mechanisms used to connect to the connecting parts of the wheel, enabling the hoisting connection device to adapt to the hoisting of wheels of different sizes.

[0023] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein.

[0026] like Figure 1 As shown, this utility model provides a hoisting connection device, which includes an adjustment mechanism 1, a fixing mechanism 2, and two connecting mechanisms 3. The adjustment mechanism 1 includes a main rod 11 and an adjusting tube 12. One end of the main rod 11 extends into the cavity of the adjusting tube 12 and can slide and be positioned therein to adjust the length of the adjustment mechanism 1. One connecting mechanism 3 is located on the part of the main rod 11 outside the adjusting tube 12, and the other connecting mechanism 3 is located on the end of the adjusting tube 12 facing away from the main rod 11. The two connecting mechanisms 3 are respectively used for detachable connection with two connecting parts of the rotating wheel. The main rod 11 and the adjusting tube 12 are connected to the hoisting equipment through the fixing mechanism 2.
[0027] Specifically, the end of the main rod 11 extends into the internal cavity of the adjusting pipe 12 and can reciprocate along the length of the cavity. Two connecting mechanisms 3 are respectively connected to the outer ends of the main rod 11 and the adjusting pipe 12. When the main rod 11 moves toward the adjusting pipe 12, the length of the adjusting mechanism 1 decreases, thereby reducing the distance between the two connecting mechanisms 3 on both sides of the length direction of the adjusting mechanism 1; when the main rod 11 moves away from the adjusting pipe 12, the length of the adjusting mechanism 1 increases, thereby increasing the distance between the two connecting mechanisms 3 on both sides of the length direction of the adjusting mechanism 1. Before hoisting the wheel, the length of the adjusting mechanism 1 is adjusted, thereby adjusting the distance between the two connecting mechanisms 3 so that the two connecting mechanisms 3 can be connected to the two connecting parts of the wheel respectively. Therefore, the hoisting connecting device of this utility model can adjust the distance between the two connecting mechanisms 3 used to connect with the connecting parts of the wheel, so that the hoisting connecting device can be adapted to hoisting wheels of different sizes.
[0028] In some embodiments of this utility model, the fixing mechanism 2 includes a first crossbar 21, a first connector 22, and a second connector 23. The first crossbar 21 is connected to the hoisting equipment. The main rod 11 is connected to the first crossbar 21 through the first connector 22, and the adjusting pipe 12 is connected to the first crossbar 21 through the second connector 23 to fix the position of the main rod 11 in the cavity of the adjusting pipe 12.
[0029] Specifically, the adjustment mechanism 1 is connected to the first crossbar 21 through the first connector 22 and the second connector 23, thereby forming a rectangular frame structure. The length of the adjustment mechanism 1 is fixed under the constraint of the fixing mechanism 2.
[0030] In some embodiments of this utility model, the first connecting member 22 and the second connecting member 23 are both lifting bolts, the main rod 11 and the adjusting tube 12 are both provided with vertically extending threaded holes, and the distance between the first connecting member 22 and the second connecting member 23 in the length direction of the first crossbar 21 is adjustable so that the two lifting bolts are threadedly connected to the two threaded holes one by one.
[0031] Specifically, the connection positions of the first connector 22 and the second connector 23 on the first crossbar 21 are adjusted so that the distance between the first connector 22 and the second connector 23 in the length direction of the first crossbar 21 is equal to the distance between the threaded hole of the main rod 11 and the threaded hole of the adjusting tube 12, so that the first connector 22 and the second connector 23 can respectively connect the main rod 11 and the adjusting tube 12 to the first crossbar 21.
[0032] like Figure 2As shown, in some embodiments of this utility model, the first crossbar 21 has a vertically extending strip hole 211, the length direction of the strip hole 211 is consistent with the length direction of the first crossbar 21; the first connector 22 and the second connector 23 are inserted into the strip hole 211, and the two can slide in the strip hole 211 to adjust their distance, and can be fixedly connected to the first crossbar 21 by a nut.
[0033] Specifically, the first connector 22 and the second connector 23 can slide along the length of the slot 211 within the slot 211, and are connected to nuts that limit their movement and prevent them from slipping downwards out of the slot 211. During hoisting, the hoisting equipment is connected to the first crossbar 21 via ropes. Under the influence of gravity, the first connector 22 and the second connector 23 are pressed against the upper surface of the first crossbar 21 by the nuts connected to their tops. Due to gravity and the friction between the nuts and the first crossbar 21, the first connector 22 and the second connector 23 remain vertical during hoisting and will not slide within the slot 211.
[0034] In some embodiments, the lifting bolt is fixedly connected to the first crossbar 21 by two nuts, with the two nuts pressing against the top and bottom surfaces of the first crossbar 21 respectively.
[0035] In some embodiments of this utility model, an annular washer is provided between the nut and the first crossbar 21 to improve the reliability of the connection. In some embodiments of this utility model, the first crossbar 21 has multiple vertical through holes, and a lifting bolt passing through the threaded hole can be fixedly connected to any of the through holes.
[0036] Specifically, the lifting bolts pass vertically through the threaded holes and through holes from bottom to top to connect the main rod 11 or the adjusting pipe 12 to the first crossbar 21.
[0037] In some embodiments of this utility model, in order to balance the forces during the hoisting process and to ensure that the wheel can be hoisted stably, the two through holes of the first horizontal bar 21, which are provided with lifting bolts, are made to be equidistant from the center of the first horizontal bar 21 in the length direction.
[0038] In some embodiments of this utility model, in order to balance the forces during the hoisting process and to ensure that the wheel can be hoisted stably, the centers of the two connecting mechanisms 3 and the distance adjustment mechanism 1 are equal in length direction.
[0039] In some embodiments of this utility model, the connecting mechanism 3 is a lifting eye bolt, which is threadedly connected to the connecting part of the rotating wheel.
[0040] Specifically, the connecting part of the wheel is provided with a connecting hole with internal threads, and the eye bolt is threaded into the connecting hole to connect the wheel to the lifting connection device.
[0041] In another aspect, this utility model provides a hoisting device, which includes the hoisting connection device in the above embodiments and also has the advantages of the above embodiments.
[0042] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0043] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0044] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
