[0030] Referring to Figure 1 and Figure 2 , the utility model discloses a kind of auxiliary hoisting device 200 for elevator, which includes main rotating rod 1, vertical rod 2, boom 3, connecting pull rod 4 and electric hoist 5. Main rotating rod 1 is rotationally arranged with external platform, specifically, main rotating rod 1 can be directly abutted with external platform to realize rotation and optionally set jack hole on external platform to improve the stability of rotation. Or set rotating device to realize rotation, so as to reduce the frictional resistance generated by rotation, so that the device rotates more smoothly. The vertical rod 2 of the auxiliary hoisting device 200 for elevator is fixedly arranged on the main rotating rod 1;Boom 3 is connected with vertical rod 2 and is arranged at an angle with vertical rod 2;One end of connecting pull rod 4 is connected with boom 3, and the other end is connected with vertical rod 2 or main rotating rod 1;Electric hoist 5 is fixedly arranged at one end of boom 3 away from connecting pull rod 4, and can directly release and retract its own hoisting rope at one end of boom 3. In some specific embodiments, boom 3 and vertical rod 2 are rotatably connected, and the angle and position of boom 3 and vertical rod 2 are fixed by connecting pull rod 4.

[0031] It can be understood that by directly arranging the electric hoist 5 at the end of the boom 3 away from the connecting pull rod 4, the heavy object is directly lifted or dropped at the end of the boom 3, unlike the existing hoisting device, the electric hoist 5 is arranged on the vertical rod 2, and the lifting rope reaches the boom 3 through a plurality of rollers, which is not only inconvenient to install, but also easy to interfere during lifting, so that the device is not easy to balance, and there is a safety hazard for the operator when operating. The auxiliary hoisting device 200 for the elevator of the utility model directly arranges the electric hoist 5 at the end of the boom 3, reduces the exposed wiring of the lifting rope on the vertical rod 2 and the boom 3, and reduces the setting of the roller to reduce the structural complexity, which can improve the lifting stroke of the electric hoist 5 to a certain extent. The length of the lifting rope is saved. Moreover, due to the reduction of the wiring layout of the lifting rope on the vertical rod 2 and the boom 3, on the one hand, the device reduces the interference of the external environment on the lifting rope during hoisting and lifting, so that the device runs more stably, and on the other hand, reduces the risk of being injured by the lifting rope when the construction personnel operate. And by setting the connecting pull rod 4, a part of the force generated by the heavy object on the boom 3 is offset, in other words, the setting of the connecting pull rod 4 can balance the stress condition of the boom 3, thereby improving the load capacity of the boom 3, ensuring the strength of the structure, and reducing the strength specification requirement of the materials of the boom 3 and the vertical rod 2.

[0032] As shown in Figure 1 and Figure 2 In some embodiments, the auxiliary hoisting device 200 for the elevator of the utility model further comprises a diagonal brace 6, the diagonal brace 6 is arranged on the side of the vertical rod 2 away from the connecting pull rod 4; the two ends of the diagonal brace 6 are respectively detachably connected with the boom 3 and the vertical rod 2, and the diagonal brace 6 and the boom 3 and the vertical rod 2 form a triangle. It can be understood that by setting the diagonal brace 6 and arranging the diagonal brace 6 and the connecting pull rod 4 on the two sides of the vertical rod 2 respectively, when the boom 3 hoists the heavy object, the connecting pull rod 4 pulls the boom 3 downward on one side of the vertical rod 2, and the diagonal brace 6 pushes the boom 3 upward on the other side of the vertical rod 2, which can ensure that the vertical rod 2 and the boom 3 are balanced, avoid the connection structure from being damaged due to excessive stress, and at the same time, such arrangement not only further improves the strength of the structure and makes the structure more stable, but also further reduces the material strength requirement and specification requirement of each structure.

[0033] As shown in Figure 1 and Figure 2 In some embodiments, the auxiliary hoisting device 200 for the elevator of the utility model further comprises a support frame 7, which is rotatably connected with the main rotating rod 1 and is used for fixedly connecting with an external structure, the support frame 7 is a polygonal structure and is rotatably connected with the main rotating rod 1 through a bearing. It can be understood that by arranging the support frame 7, the rotation of the main rotating rod 1 can be more stable, and the stress condition during hoisting can be balanced to prevent the main rotating rod 1 from tilting, bending or deforming.

[0034] In some embodiments, the main rotating rod 1, the vertical rod 2, the cantilever 3 and the connecting pull rod 4 are detachably connected. Since the two ends of the diagonal brace 6 are detachably connected with the vertical rod 2 and the cantilever 3 respectively, it can be understood that, by detachable connection between various structures, when the auxiliary hoisting device 200 for the elevator is not used, the upper part of the auxiliary hoisting device 200 for the elevator can be folded by detaching any end of the diagonal brace 6 and any end of the connecting pull rod 4, so as to reduce the space occupation and facilitate transportation.

[0035] In some embodiments, the auxiliary hoisting device 200 for the elevator of the utility model further comprises a mounting seat 8, which is arranged between the main rotating rod 1 and the vertical rod 2 and is used for connecting the main rotating rod 1 and the vertical rod 2, that is, the main rotating rod 1 and the vertical rod 2 are fixedly connected through the mounting seat 8. The end of the connecting pull rod 4 away from the cantilever 3 is fixedly connected with the mounting seat 8, that is, the connecting pull rod 4 is connected with the vertical rod 2 or the main rotating rod 1 through the mounting seat 8. Specifically, as shown in Figure 1 and Figure 2 , the mounting seat 8 is triangular and is connected with the vertical rod 2, the main rotating rod 1 and the connecting pull rod 4 respectively. It can be understood that, since the electric hoist 5 is arranged at one end of the cantilever 3 instead of being arranged on the vertical rod 2 or the main rotating rod 1, the wiring of the hoisting rope is reduced, the mounting seat 8 can also serve as a handle or a handle mounting structure for the construction personnel to rotate the auxiliary hoisting device 200 for the elevator, which simplifies the device structure and facilitates the operation of the construction personnel. In some specific embodiments, the mounting seat 8 can be detachably connected with the vertical rod 2 or the main rotating rod 1, and in other embodiments, the mounting seat 8 can be fixedly connected with any one of the vertical rod 2 or the main rotating rod 1 and detachably connected with the other one. In this way, the device can be easily folded and transported when not in use. In some specific embodiments, the connecting pull rod 4 and the vertical rod 2 are arranged in parallel and are spaced apart. It can be understood that, in this way, the stress between the connecting pull rod 4 and the cantilever 3 can be better guaranteed. Of course, the connecting pull rod 4 and the vertical rod 2 can also not be kept parallel, which can be determined according to the actual stress condition.

[0036] Referring to Figure 1 and Figure 2 , the utility model also discloses a kind of elevator 100, including guide rail frame and the cage 120 that can be moved up and down along guide rail frame, and above-mentioned auxiliary hoisting device 200 for the elevator. Among them, the main rotating rod 1 of auxiliary hoisting device 200 for the elevator is rotatably connected with the top platform of cage 120;The support frame 7 of auxiliary hoisting device 200 for the elevator is fixedly connected with the frame structure of cage 120, and the fixed connection mode of support frame 7 and the frame structure of cage 120 is detachable connection.

[0037] In some embodiments, either the main rotating rod 1 or the top platform of the cage 120 is provided with a ball head shaft (not shown in the drawings), and the other is provided with a groove matched with the ball head shaft. It can be understood that by providing the ball head shaft, the friction between the main rotating rod 1 and the top platform of the cage 120 can be reduced, so that the rotation of the main rotating rod 1 is more smooth. In an alternative embodiment, either the main rotating rod 1 or the top platform of the cage 120 is provided with a plane bearing, and the other is provided with a bearing seat or other structure that can cooperate with the plane bearing. The plane bearing reduces the frictional resistance between the main rotating rod 1 and the top platform of the cage 120.

[0038] When the elevator 100 is autonomously added, the guide rail standard section 110 placed on the cage 120 is lifted by the auxiliary hoisting device 200 of the elevator, and then the construction personnel operate the main rotating rod 1 to rotate the guide rail standard section 110 to above the guide rail frame and lower the guide rail standard section 110, and then the construction personnel fix the guide rail standard section 110 with the guide rail frame below, and release the hoisting connection between the guide rail standard section 110 and the auxiliary hoisting device 200 of the elevator, and install the corresponding number of guide rail standard sections 110 according to the actual operating height requirement.

[0039] When the elevator 100 is autonomously removed, the construction personnel rotate the hoisting arm 3 of the auxiliary hoisting device 200 of the elevator to above the guide rail frame, lower the hoisting rope through the electric hoist 5, and the construction personnel remove the uppermost guide rail standard section 110 of the guide rail frame and complete the hoisting through the auxiliary hoisting device 200 of the elevator, then the construction personnel rotate the main rotating rod 1 to make the guide rail standard section 110 fall into the top platform of the cage 120, and release the hoisting connection between the guide rail standard section 110 and the auxiliary hoisting device 200 of the elevator, complete the removal of one guide rail standard section 110, and then repeatedly remove again until the removal is completed.

[0040] The auxiliary hoisting device of the elevator directly sets the electric hoist at the end of the hoisting arm away from the connecting pull rod, directly lifts or lowers the heavy object at one end of the hoisting arm, reduces the exposed wiring of the hoisting rope on the stand and the hoisting arm, and reduces the setting of the roller to reduce the structural complexity. To a certain extent, the travel of the electric hoist can be improved, and the length of the hoisting rope can be saved. Moreover, due to the reduction of the wiring layout of the hoisting rope on the stand and the hoisting arm, on the one hand, the device reduces the interference of the outside to the hoisting rope during hoisting and lifting, and on the other hand, the risk of being injured by the hoisting rope during operation is reduced. And by setting the connecting pull rod, a part of the force generated by the heavy object on the hoisting arm is offset, in other words, the setting of the connecting pull rod can balance the stress condition of the hoisting arm, thereby improving the load capacity of the hoisting arm, ensuring the strength of the structure, and reducing the strength specification requirement of the materials such as the hoisting arm and the stand.

[0041] The auxiliary hoisting device for the elevator can realize autonomous adding and removing of the elevator without the assistance of the tower crane or the steam crane, and improves operation efficiency and reduces installation and removal cost.
