Description

Technical Field

[0001] The utility model relates to the technical field of truss steel structure installation devices, and more specifically, to a large truss steel structure greenhouse jacking installation device. Background Art

[0002] At present, in the construction of large-scale truss steel structure greenhouses, the construction technology of overall hoisting after welding is generally adopted. For example, if there are structures such as toll islands under the greenhouse, due to the positioning requirements of the lifting equipment, the structure must wait until the greenhouse is hoisted. After completion, the construction can affect the construction progress of the concrete structure. At the same time, large-scale truss steel structure hoisting generally uses large-scale lifting equipment for lifting operations, which has high safety risks and poor positioning accuracy. If the site flatness and bearing capacity are insufficient, hoisting cannot be carried out. Utility Model Content

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0020] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a large-scale truss steel structure greenhouse jacking and installation device, including a plurality of jacking and installation components 2 arranged at intervals along the longitudinal direction of the truss steel structure greenhouse 1, the jacking and installation components 2 include a jacking device 21, a connecting joint 22, a plurality of self-locking pads 23 and a plurality of bearing pads 24; the top of the vertical movable end of the jacking device 21 is fixedly connected to the connecting joint 22; the bearing pad 24 is arranged on one side of the jacking device 21, and in conjunction with the extension and retraction of the vertical movable end of the jacking device 21, the self-locking pads 23 and the bearing pads 24 are alternately vertically stacked above the connecting joint 22 and on one side of the jacking device 21 to perform jacking and installation of the truss steel structure greenhouse.

[0022] In this technical solution, before welding the truss steel structure greenhouse 1, the number of the jacking installation components 2 and the bearing capacity requirements of the location where the jacking installation components 2 are placed are determined first, and foundation treatment is performed if necessary. After the bearing capacity meets the requirements, the jacking equipment 21 and the bearing pads 24 are installed. At this time, the number of the bearing pads 24 to be installed first can be determined according to the height of the jacking equipment 21 and the connecting joint 22, so that the bearing pads 24 are slightly higher than the jacking equipment 21, and then the assembly and welding of the truss steel structure greenhouse 1 is completed on the bearing pads 24. After the truss steel structure greenhouse is assembled, it is supported on the bearing pads 24 of each of the jacking installation components 2, and then the truss steel structure greenhouse 1 is lifted upward by extending the vertical movable ends of each of the jacking devices 21, so that it is separated from the bearing pads 24, and it continues to be lifted upward to a certain height and remains motionless, and another bearing pad is placed on the bearing pad 24 on one side; then the vertical movable ends of each of the jacking devices 21 are retracted to make the truss steel structure greenhouse 1 fall on the bearing pad 24 again, and then the self-locking pad 23 is placed on the connecting joint 22; repeat the above process, alternately stack the self-locking pad 23 and the bearing pad 24 vertically above the connecting joint 22 and on one side of the jacking device 21, until the truss steel structure greenhouse 1 is lifted to the designed height. In the above process, no large-scale hoisting equipment is required for hoisting operations, which avoids the risk of overturning and rollover caused by lifting, and is applicable to the installation of large-scale truss steel structure greenhouses on any terrain.

[0023] In another embodiment, if Figure 3 As shown, the self-locking pad 23 includes an upper structure 231 and a lower structure 232 stacked up and down to form a convex structure. The bottom surface of the lower structure 232 is provided with a groove from bottom to top, and the groove matches the shape of the upper structure 231, so that the upper structure 231 of the self-locking pad 23 located below can be inserted into the groove of the self-locking pad 23 located above. Considering that a plurality of the self-locking pads 23 are stacked up and down when in use, in order to limit the relative movement between the two adjacent self-locking pads 23 above and below and ensure the stability of the truss steel structure greenhouse 1 during the lifting process, the self-locking pad 23 is set to a convex structure. When the self-locking pads 23 are stacked, the upper structure 231 of the self-locking pad 23 located below is inserted into the groove of the self-locking pad 23 located above, so as to limit the horizontal movement of the two. The upper structure 231 and the lower structure 232 can adopt an integrally formed structure.

[0024] To further enhance the self-locking effect, the top of the upper structure 231 is provided with a plurality of insertion holes 234, and the top surface of the groove is provided with a plurality of latches 233 that match the insertion holes 234. When the upper structure 231 of the self-locking pad 23 below is inserted into the groove of the self-locking pad 23 above, each of the latches 233 in the groove is correspondingly inserted into each of the insertion holes 234 on the self-locking pad 23 below.

[0025] In another embodiment, the structure of the connection joint 22 is the same as the upper structure 231. That is, the top of the connection joint 22 is also correspondingly provided with a plurality of the plug holes 234, and when the first self-locking pad 23 is placed, the connection joint 22 is inserted into the groove at the bottom thereof, and each latch 233 in the groove is inserted into the corresponding plug hole at the top of the connection joint 22, so as to realize the stable connection between the first self-locking pad 23 and the connection joint 22.

[0026] In another embodiment, if Figure 2 As shown, the lifting device 22 is a three-way jack, which is fixed on the ground. The three-way jack can adopt the three-way jack device conventionally used in the engineering field, and its bearing capacity can meet the requirements. It includes a vertical jack, a transverse jack and a longitudinal jack. The vertical jack is used to connect with the connecting joint 22 and the self-locking pad 23 to lift the truss steel structure greenhouse 1 to the designed height, and then adjust the plane position of the truss steel structure greenhouse 1 through the longitudinal jack and the transverse jack. The three-way jacks of each of the lifting installation components 2 can be synchronously controlled by a pump station and a control system.

[0027] In another embodiment, a plurality of hinges 3 are arranged at intervals at the bottom of the truss steel structure greenhouse 1. Figure 4 As shown, the hinge 3 is used to install the column 4 below the truss steel structure greenhouse 1, and each column 4 is provided with a corresponding hinge 3. After the plane position of the truss steel structure greenhouse 1 is adjusted, the column is hoisted through each hinge 3. After the column 4 is installed, the truss steel structure greenhouse 1 is dropped onto each column 4 through the cooperation of the vertical jack and the bearing pad 24 to complete the installation of the truss steel structure greenhouse 1. The hinge 3 is used to position the top of the column 4, and the top of the column 4 can be connected to the hinge 3 to cooperate with the positioning and installation of the column 4.

[0028] In another embodiment, a reinforcing steel plate is provided at the bottom of the truss steel structure greenhouse 1 corresponding to each of the jacking installation components 2. The reinforcing steel plate is used to reinforce the truss steel structure greenhouse 1 to prevent the truss structure from being damaged during the jacking process; preferably, the reinforcing steel plate covers the positions corresponding to the self-locking pads 23 and the bearing pads 24.

[0029] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
