Moreover, its clamping claws cannot rotate and cannot cope with complex construction site environments. When installing the seismic isolation support, it may need to be rotated to a certain angle. If the device in the prior art is used, the seismic isolation support can only be placed in the specified position first, and then moved to the appropriate angle by manual pushing, which greatly increases the workload of workers. Therefore, there is an urgent need for a hoisting device for installing a seismic isolation support that is easy to transport, has a good clamping effect, and can rotate the clamped object to adjust its direction.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-4As shown, the utility model provides a hoisting device for installing a seismic isolation support, comprising: a gantry 1, a plurality of movable casters 2 are arranged at the bottom end of the gantry 1, a hanging beam 3 is arranged at the top end of the gantry 1, the hanging beam 3 is arranged horizontally, an electric hoist 4 is connected to the hanging beam 3, the bottom end of the electric hoist 4 is connected to two connecting chains 5, the bottom ends of the two connecting chains 5 are fixedly connected to the same steering structure 6, and the bottom end of the steering structure 6 is connected to a clamping structure 7;

[0030] A controller 8 is fixedly connected to one side of the gantry 1 , and the electric hoist 4 , the steering structure 6 , and the clamping structure 7 are electrically connected to the controller 8 .

[0031] By setting the steering structure 6, the device can realize the relative rotation of the clamping structure 7, so that the lower isolation support can be fine-tuned in position. By rotating the isolation support, the isolation support can be more adapted to the needs of the project and has better flexibility. By setting the clamping structure 7 and controlling the controller 8, the clamping isolation support can be controlled to ensure that the device is stable when clamping the isolation support.

[0032] Utilizing these structures, a hoisting device for installing a seismic isolation support is realized, which is easy to transport, has a good clamping effect, and can rotate the clamped object to adjust its direction.

[0033] According to a further optimized solution, the steering structure 6 includes a fixed housing 601, and two chain connectors 602 are provided on the top edge of the fixed housing 601, and the chain connectors 602 are fixedly connected to the bottom ends of the corresponding connecting chains 5;

[0034] A planetary transmission structure is provided at the bottom end of the fixed housing 601, the input end of the planetary transmission structure is transmission-connected with the output shaft of the steering motor 603, the steering motor 603 is fixedly connected to the fixed housing 601, and the output end of the planetary transmission structure is transmission-connected with the clamping structure 7;

[0035] The steering motor 603 is electrically connected to the controller 8 .

[0036] By setting up the chain connector 602, a good fixation with the connecting chain 5 can be achieved. The connecting chain 5 can be fixedly connected to the chain connector 602 by means of a hook or the like. By setting up the steering motor 603 to drive the planetary transmission structure, the torque output by the steering motor 603 can be converted into a micro-angle rotation while ensuring the stability of the center of gravity of the steering structure 6, ensuring that the seismic isolation bearing can perform a small rotation, thereby meeting the needs of the project and reducing the shaking caused by the rotation of the seismic isolation bearing.

[0037] A further optimized solution is that the planetary transmission structure includes a ring gear 604, which is fixedly connected to the bottom end of the fixed housing 601, and the output shaft of the steering motor 603 is connected to a sun gear 605, which is arranged on the inner side of the ring gear 604, and a plurality of planetary gears 606 are meshed between the sun gear 605 and the ring gear 604, and the bottom ends of the plurality of planetary gears 606 are rotatably connected to the same planet carrier 607, and the bottom end of the planet carrier 607 is fixedly connected to the clamping structure 7.

[0038] Further optimized solution, the clamping structure 7 includes a circular plate 701, the top of the circular plate 701 is fixedly connected to the bottom of the planetary frame 607, the circumferential side of the circular plate 701 is rotatably connected to the tops of several clamping arms 702, the middle of the clamping arm 702 is rotatably connected to one end of a transmission rod 703, the middle of the bottom surface of the circular plate 701 is axially connected to a telescopic cylinder 706, the output shaft of the telescopic cylinder 706 is axially connected to a connecting block 705, and the end of the transmission rod 703 away from the clamping arm 702 is rotatably connected to the connecting block 705;

[0039] The telescopic cylinder 706 is electrically connected to the controller 8 .

[0040] By controlling the operation of the telescopic cylinder 706 through the controller 8, one end of the transmission rod 703 can be pushed to move, thereby driving the clamping arm 702 to clamp or release. This structural setting is more stable and can effectively avoid falling off during the clamping process.

[0041] According to a further optimized solution, a clamping head 704 is fixedly connected to one side of the bottom end of the clamping arm 702 close to the connecting block 705 .

[0042] The arrangement of the clamping head 704 can further improve the stability of the device during clamping.

[0043] According to a further optimization scheme, a detection head 707 is provided at the bottom of the connection block 705 , and the detection head 707 is electrically connected to the controller 8 .

[0044] During clamping, when the seismic isolation support enters the clamping structure 7 and contacts the connecting block 705, the detection head 707 is triggered. At this time, the controller 8 receives an electrical signal and controls the telescopic cylinder 706 to contract, thereby clamping. By setting the detection head 707, the automation level of the device can be improved, so that the device can automatically clamp the seismic isolation support.

[0045] Further optimizing the scheme, a foot brake 201 is provided on the mobile caster 2. The setting of the foot brake 201 can keep the device fixed at a specified position without moving.
