[0001] The present application relates to the field of engineering construction technology, in particular to a large component hoisting anti-seismic auxiliary device. BACKGROUND

[0002] In the case of developing overseas construction market, the construction under the environment of frequent earthquakes is increasing, and it is more and more important to ensure the construction under the environment of frequent earthquakes.

[0003] The hoisting of large components in the construction process is a construction step with high operation frequency, and the traditional hoisting of large components uses traction ropes for directional traction and wind resistance, which does not have the function of emergency and rapid reinforcement, and cannot adapt to the environment of frequent earthquakes to ensure the stability of large components, which has corresponding safety hazards. SUMMARY

[0004] The purpose of the present application is to overcome the defects of the prior art, and to provide a large component hoisting anti-seismic auxiliary device to solve the problem that the traction of large component hoisting by traction ropes cannot ensure the stability of large components in an earthquake.

[0005] To achieve the above purpose, the present application provides a large component hoisting anti-seismic auxiliary device, which replaces the traction ropes used in the circumferential distribution of the existing large component hoisting by a traction support structure, which can conduct directional traction force and support the ground when an earthquake occurs to deal with the problem of large component shaking.

[0006] The standard section is composed of a rod body and a first screw head and a first nut connected to both ends thereof and capable of cooperating with each other;

[0007] The variable telescopic section is composed of an outer sleeve and an inner sleeve telescopically connected to one end thereof, and the other end of the outer sleeve is connected with a second screw head capable of being threadedly matched with the first nut;

[0008] In use, the standard section is connected with the variable telescopic section by threadedly matching the first nut with the second screw head, and then the end of the standard section provided with the first screw head is connected with the large component by the connecting piece to complete the installation.

[0009] By adopting this technical scheme, the rod-shaped structure composed of the standard section and the variable telescopic section can be telescopic, which can not only replace the traction ropes and use the telescopic function to safely pull the large component, but also can use the rod-shaped structure as a support when an earthquake occurs, so that the large component is stably supported on the ground with the hoisting of the large component, thereby coping with the environment of frequent earthquakes and ensuring the stability and safety of the hoisting of the large component under the environment of frequent earthquakes.

[0010] Further, the inner end of the outer sleeve connected with the inner sleeve is provided with a first limiting cylinder, and the first limiting cylinder is in sliding cooperation with the outer wall of the inner sleeve.

[0011] A second limiting cylinder is provided on the outside of one end of the inner sleeve connected to the outer sleeve, and the second limiting cylinder is slidably matched with the inner wall of the outer sleeve.

[0012] By adopting this technical solution, the outer sleeve and the inner sleeve are connected in a limited sliding manner through the limiting cooperation of the first limiting cylinder and the second limiting cylinder, thereby ensuring the integrity of the structure.

[0013] Furthermore, the inner sleeve is provided with an automatic locking structure, and relative locking with the outer sleeve is achieved through the automatic locking structure.

[0014] By adopting this technical solution, the overall length of the inner sleeve can be fixed after it is extended and retracted relative to the outer sleeve, providing the prerequisite for quickly supporting large components on the ground when frequency earthquakes occur.

[0015] Furthermore, the automatic locking structure includes a locking handle connected to the side of the inner sleeve away from the outer sleeve, a connecting rod provided inside the inner sleeve, and a telescopic mechanism connected to the inner end of the inner sleeve close to the outer sleeve; wherein the locking handle is connected to the telescopic mechanism via the connecting rod, and the telescopic mechanism can be extended to the outside of the inner sleeve;

[0016] The locking handle is rotatably connected to the inner wall of one side of the inner sleeve and passes through the other side of the inner sleeve to the outside of the inner sleeve. The locking handle can pull the connecting rod downward under the action of its own gravity to drive the telescopic mechanism to extend to the outside of the inner sleeve and abut against the inner wall of the outer sleeve.

[0017] By adopting this technical solution, the locking handle can pull the telescopic mechanism through the connecting rod under the action of its own weight so that it extends out of the inside of the inner sleeve and abuts against the inner wall of the outer sleeve, thereby achieving mutual locking of the two by increasing the friction between the inner sleeve and the outer sleeve; based on this, during actual operation, when the staff holds the structure for pulling, they release the lock between the inner sleeve and the outer sleeve by holding the locking handle, so as to cope with the displacement caused by the shaking of the large component through the relative expansion and contraction between the two, thereby ensuring the safety of the staff; at the same time, when an earthquake occurs, the locking handle can be released to lock the inner sleeve and the outer sleeve, and then supported on the ground, so as to achieve the purpose of quickly stabilizing the large component through support.

[0018] Furthermore, the telescopic mechanism includes a sliding sleeve, a fixed sleeve, a rotating rod, a locking head and a tension spring; wherein,

[0019] The sliding sleeve and the fixed sleeve are respectively sleeved on the connecting rod, and the sliding sleeve is fixedly connected to the inner sleeve and slidably connected to the connecting rod, and the fixed sleeve is fixedly connected to the connecting rod;

[0020] Two rotating rods are arranged, and one end of the two rotating rods is respectively connected with the sliding sleeve and the fixed sleeve in rotation, and the other end is connected in common rotation;

[0021] The side wall of the inner sleeve is provided with a through hole corresponding to the locking head, the locking head is connected in sliding with the through hole, and the length of the locking head is greater than the length of the through hole, and one end of the locking head extending into the inner sleeve is connected with one end of the two rotating rods connected in common rotation;

[0022] The tension spring is sleeved on the rod of the connecting rod between the sliding sleeve and the fixed sleeve, and the two ends of the tension spring are respectively connected with the sliding sleeve and the fixed sleeve.

[0023] By adopting the technical scheme, after the connecting rod pulls the fixed sleeve under the action of the locking handle, the fixed sleeve is close to the sliding sleeve, so that the two rotating rods synchronously push the locking head to extend out of the inner sleeve, so as to achieve the mutual locking purpose of the inner sleeve and the outer sleeve; the setting of the tension spring makes the fixed sleeve have a tendency to move towards the sliding sleeve in a natural state, and can increase the locking head out of the inner sleeve under the action of the locking handle pulling the connecting rod in a natural state, so as to increase the friction between the inner sleeve and the outer sleeve, and further increase the locking effect between the inner sleeve and the outer sleeve.

[0024] Further, the inner sleeve is connected with a conical head at the end away from the outer sleeve.

[0025] By adopting the technical scheme, the difficulty of inserting into the ground is reduced, and the efficiency of stabilizing the large component is improved by quickly inserting into the ground.

[0026] Compared with the prior art, the present application has the following beneficial effects:

[0027] The standard section and the variable telescopic section are used to form a telescopic rod-shaped structure, which can replace the traction rope and use the telescopic function to safely pull the large component, and when an earthquake occurs, the rod-shaped structure can be used as a support to stably support the large component on the ground, so as to cope with the frequent earthquake environment and ensure the stability and safety of the large component during hoisting in the frequent earthquake environment.
