[0033] Example 1

[0034] Reference Figures 1-3 This embodiment provides an auxiliary device for fabricating the inner and outer formwork of a dome, including a crane 100 (existing technology). A connecting assembly 200 is suspended from the cantilever end of the crane 100. The connecting assembly 200 includes a fixed base 201 and a connecting piece 202 connected to the fixed base 201. The top of the fixed base 201 has a flange for connecting to the steel cable of the crane cantilever. A hook assembly 300 includes a fixing ring 301 fixedly connected to the connecting piece 202. Four hinge seats 301a are evenly arranged along the circumference of the fixing ring 301. Connecting ropes 302 are hinged to the hinge seats 301a, and hooks 303 are connected to the ends of the connecting ropes 302. The hooks 303 are used to suspend the pre-formed dome.

[0035] In this embodiment, after the dome template is pre-set on the construction site, the dome template is hoisted onto the building using a crane 100, a connecting component 200, and a hook component 300.

[0036] Example 2

[0037] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0038] The fixing base 201 is cylindrical. A through groove 201a is provided axially from its end face. A rectangular groove 201b is provided inside the through groove 201a, the width of which is greater than the width of the through groove 201a. A first through hole 201c is provided inside the fixing base 201. A movable ring 203 is provided inside the first through hole 201c, and the movable ring 203 can move within the first through hole 201c. A movable block 203a is provided on the side of the movable ring 203, located within the rectangular groove 201b. The movable block 203a is provided with a radially sliding groove 203. b. A sliding block 204 is provided in the sliding groove 203b. One end of the sliding block 204 passes through the through groove 201a and is provided with an inclined surface 204a to form a wedge shape. A first spring 204b is provided between the sliding block 204 and the sliding groove 203b. That is, under the action of the first spring 204b, the sliding block 204 extends out of the through groove 201a. A second spring 207 is provided between the moving block 203a and the end face of the rectangular groove 201b near the connector 202. That is, in the initial state, the moving block 203a and the moving ring 203 are at the end away from the fixed seat 201.

[0039] It should be noted that in this embodiment, at least two sliding blocks 204 are symmetrically arranged.

[0040] Furthermore, the connector 202 is provided with a circular groove 202a, the diameter of which is the same as the outer diameter of the fixed seat 201, that is, the fixed seat 201 can be embedded in the circular groove 202a. A slider groove 202f is provided on the inner side of the circular groove 202a. When the fixed seat 201 can be embedded in the circular groove 202a, the slider 204 is embedded in the slider groove 202f, thus fixing the connector 202 and the fixed seat 201 together.

[0041] Furthermore, a frustum 202b is provided in the circular groove 202a. When the fixing seat 201 is connected to the connector 202, the frustum 202b can be embedded in the first through hole 201c. Correspondingly, the frustum 202b is provided with a through second through hole 202c.

[0042] The rectangular groove 201b has a guide groove 201d on the side away from the connector 202, which is radially along the fixed base 201. The moving block 203a has a long groove 203c that extends through the sliding groove 203b. The sliding block 204 has a limiting post 204c, which passes through the long groove 203c and is embedded in the guide groove 201d. Therefore, the guide groove 201d limits the range of movement of the sliding block 204 radially along the connector 202.

[0043] One end of the guide groove 201d away from the center of the fixed seat 201 is connected to an inclined groove 201e. The other end of the inclined groove 201e extends towards the end face and axis of the fixed seat 201. That is, the angle between the inclined groove 201e and the guide groove 201d is an acute angle, and the ends of the inclined groove 201e and the guide groove 201d away from the center of the fixed seat 201 coincide. The distance between the other ends of the inclined groove 201e and the guide groove 201d and the axis of the fixed seat 201 is the same. The limiting post 204c is embedded in the guide groove 201d or the inclined groove 201e. That is, when it is necessary to separate the connector 202 and the fixed seat 201, the connector 202 is moved. The slider groove 202f carries the sliding block 204 along the inclined groove 201e. During the movement, the sliding block 204 retracts into the fixed seat 201, so the connector 202 is no longer restricted, and the separation is completed.

[0044] Furthermore, a rotating cylinder 205 is disposed within the first through hole 201c. An annular groove 205a is provided on the outer periphery of the rotating cylinder 205. A movable ring 203 is sleeved outside the annular groove 205a, meaning that a portion of the rotating cylinder 205 is located within the movable ring 203, allowing relative rotation with the movable ring 203, but preventing relative axial movement. A spiral groove 201f is provided on the side of the first through hole 201c, and a boss 205b is provided on the outer side of the rotating cylinder 205, embedding within the spiral groove 201f. Therefore, the movement of the rotating cylinder 205 is spiral.

[0045] Among them, the end face of the rotating cylinder 205 near the frustum 202b is provided with a limiting hole 205c.

[0046] A pin hole 202d is provided on the end face of the frustum 202b near the rotating cylinder 205. A notch is provided on the end face of the connector 202, corresponding to the position of the sliding block 204. When the operating connector 202 is connected to the fixed base 201, the end face of the frustum 202b fits against the end face of the rotating cylinder 205, and the pin hole 202d is coaxial with the limiting hole 205c, and their diameters are the same. A separating pin 206 is provided inside the pin hole 202d, and a third spring 208 is provided between the separating pin 206 and the bottom surface of the pin hole 202d. Therefore... Once the end face of the frustum 202b is in contact with the end face of the rotating cylinder 205, one end of the separating pin 206 is embedded in the limiting hole 205c. At this time, the connecting piece 202 cannot move and its position is limited. This is because once the connecting piece 202 is operated to separate the fixed seat 201, the fixed seat 201 moves with the sliding block 204 in the inclined groove. At the same time, the moving ring 203 moves with the rotating cylinder 205. However, since the separating pin 206 restricts the rotation of the rotating cylinder 205, the rotating cylinder 205 cannot move spirally, which means that the sliding block 204 cannot move.

[0047] When the fixed base 201 is connected to the connector 202, one end of the sliding block 204 is embedded in the slider groove 202f, the limiting post 204c is located at the connection of the guide groove 201d and the inclined groove 201e, and one end of the separating pin 206 is embedded in the limiting hole 205c.

[0048] Preferably, the pin hole 202d is provided with a through-hole 202e, and an operating ring 206a is sleeved on the through-hole 202e. The separating pin 206 is provided with a crossbar 206b, which passes through the through-hole 202e and connects to the operating ring 206a. That is, when it is necessary to separate the connecting piece 202 and the fixing seat 201, the operating ring 206a is controlled to make the separating pin 206 disengage from the limiting hole 205c, and then the connecting piece 202 can be separated from the fixing seat 201.

[0049] In this embodiment, when hoisting the dome template, the connector 202 and hook assembly 300 are first connected to the dome template, then the connector 202 is fixedly connected to the fixed base 201, and then the hoist 100 is used for lifting and transferring.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
