Description

Technical Field

[0001] The utility model relates to the technical field of installation equipment, in particular to a TMD hoisting device. Background Art

[0002] TMD is the abbreviation of tuned mass dissipater. TMD is one of the earliest passive control devices used in structural vibration control. The mechanism of TMD vibration control of structure is: when the structure vibrates under external excitation, it drives the TMD subsystem to vibrate together. The inertial force generated by the relative motion of the TMD subsystem reacts to the structure, and the inertial force is tuned to control the vibration of the structure. When the natural frequency of the TMD system is basically consistent with the natural frequency of a certain vibration mode of the structure, the TMD system has the best control effect on the vibration response of this vibration mode.

[0003] The weight of a TMD is one ton. When installing a TMD in the prior art, the components constituting the TMD are usually assembled on the first floor, and then the TMD and the staff are lifted to the beam close to the second floor by lifting equipment such as a scissor lift. A steel plate is preset in the beam. Then, the staff welds the TMD lifted to a high place to the steel plate to complete the installation. However, the mass of the TMD is relatively large. When lifting the TMD by a lifting equipment such as a scissor lift, the TMD must first be lifted onto the scissor lift by a lifting equipment, and then the TMD is lifted. However, the installation position of the TMD has high requirements. When the TMD is lifted from the first floor to a lifting equipment such as a scissor lift, it is difficult to accurately adjust the installation position of the TMD to meet the position requirements of the TMD. Therefore, it is necessary to improve the design of the installation equipment of the TMD. Utility Model Content

In the present application, the distance between the steel plate 8 and the building wall is measured to determine the distance between the small hole for the steel wire rope 2 to pass through and the building wall, so that a small hole for the steel wire rope 2 to pass through is set on the second floor slab 5, so that the position of the lifted TMD13 and the steel plate 8 corresponds exactly, which changes the way of installing TMD13 in traditional technology and is conducive to improving the installation efficiency and positioning accuracy of TMD13.

[0029] The clamping mechanism 7 includes a clamping assembly 71, which is provided with two groups and symmetrically distributed on both sides of the mounting frame 1, each group of the clamping assembly 71 includes an I-beam 711 that is penetrated and slidably matched with the mounting plate 6, a sliding block 712 fixed to the top of the I-beam 711, and an outer L-shaped plate 713 fixed to the bottom of the I-beam 711 and supporting the bottom of the TMD13; a straight groove 61 is penetrated on the mounting plate 6 for the I-beam 711 to slide with, the bottom of the upper section of the I-beam 711 is in contact with the upper surface of the mounting plate 6, and the top of the lower section of the I-beam 711 is in contact with the bottom surface of the mounting plate 6; the clamping mechanism 7 also includes a driving assembly 72 for driving the sliding blocks 712 in the two groups of clamping assemblies 71 to move closer to or away from each other.

The rubber plate 91 is made of rubber material, and its surface has a large friction coefficient. The provision of the rubber plate 91 and the strip grooves 911 increases the friction between the horizontal section of the outer L-shaped plate 713 and the bottom of the TMD13, reduces the probability of the position of the TMD13 shaking during the process of the outer L-shaped plate 713 lifting the bottom of the TMD13, and is conducive to the smooth installation of the TMD13.

The tops of the horizontal sections of the two inner L-shaped plates 7111 respectively support both sides of the top of the TMD 13. The two inner L-shaped plates 7111 support both sides of the top of the TMD 13, which strengthens the support effect on the TMD 13 and is conducive to the smooth installation of the TMD 13.

[0034] Four steel wire ropes 2 are arranged in a rectangular array. Two first vertical plates 11 and four second vertical plates 12 are fixed on the top of the mounting frame 1. The two first vertical plates 11 are symmetrically distributed on both sides of the mounting frame 1. The two first vertical plates 11 and the four second vertical plates 12 are distributed in a rectangular shape. The first vertical plate 11 is located between the two second vertical plates 12 on the same side of the mounting frame 1. The control component 3 includes an upper motor 31 fixed on one of the first vertical plates 11, a driving gear 32 fixed to the output end of the upper motor 31, and a gear 32 rotatably mounted on the two second vertical plates 1 symmetrically arranged. 2 and parallel to the axis of the driving gear 32, a driven gear 34 fixedly sleeved on the transmission rod 33 and meshing with the driving gear 32, and a winding wheel 35 fixedly sleeved on the transmission rod 33; the driving gear 32 is coaxially arranged with the output end of the upper motor 31, the transmission rod 33 is provided with two and symmetrically distributed on both sides of the output end of the upper motor 31, the driven gear 34 and the winding wheel 35 are coaxially arranged with the transmission rod 33, and the four winding wheels 35 are also distributed in a rectangular array, and one end of the wire rope 2 is wound around and fixed on the winding wheel 35.

[0035] The use principle of a TMD lifting device in this embodiment is as follows: the staff only needs to start the lower motor 722, and the lower motor 722 will drive the rotating rod 721 to rotate after it starts working. Since the two sliding blocks 712 are symmetrically distributed on the two threads of the rotating rod 721, the sliding blocks 712 are fixed to the I-beam 711, and the I-beam 711 slides with the slot 61, so that the two sliding blocks 712 are close to each other, and the I-beam 711 and the outer L-shaped plate 713 move synchronously with the sliding blocks 712, so that the outer L-shaped plates 713 on both sides are close to each other, until the two outer L-shaped plates 713 cooperate and clamp the TMD13, and then the lower motor 722 is turned off. Subsequently, the staff starts the upper motor 31. After the upper motor 31 starts working, it drives the driving gear 32 to rotate, so that the driven gear 34, the transmission rod 33 and the winding wheel 35 all rotate, so that the wire rope 2 is gradually tightened on the winding wheel 35. In this process, since the driven gears 34 on both sides are meshed with the middle driving gear 32, the four wire ropes 2 are synchronously wound, and the mounting plate 6 rises, and the outer L-shaped plates 713 on both sides cooperate with the inner L-shaped plates 7111 on both sides to hoist TMD13. When the positions of TMD13 and the steel plate 8 correspond, the upper motor 31 is turned off, and TMD13 is welded to the steel plate 8 to complete the installation operation of TMD13 (the staff can use the scissors car to rise to a position close to the beam 51 for welding operations). In the present application, the distance between the steel plate 8 and the building wall is measured to determine the distance between the small hole for the steel wire rope 2 to pass through and the building wall, so that a small hole for the steel wire rope 2 to pass through is set on the second floor slab 5, so that the position of the lifted TMD13 and the steel plate 8 corresponds exactly, which changes the way of installing TMD13 in traditional technology and is conducive to improving the installation efficiency and positioning accuracy of TMD13.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
