Description

Position control device and control method for assembling prefabricated column segments Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a position control device and a control method for assembling prefabricated column segments. Background Art

[0002] The technology of assembling prefabricated column segments is gradually being used in municipal bridge projects and other projects. For example, if the extra-long columns under the large cap beam (generally up to 20 meters) are constructed by hoisting prefabricated columns, the on-site construction efficiency can be greatly improved. During the construction process, the prefabricated columns need to be installed in the predetermined installation position to facilitate the next step of construction. Due to the large mass and volume of the prefabricated columns, the shaking of the prefabricated columns during the installation process will cause certain difficulties in the positioning of the prefabricated columns. In order to prevent greater difficulties in the installation of the prefabricated cap beam in the next process, measures need to be taken to improve the installation accuracy of individual columns.

[0003] Therefore, how to improve the construction efficiency of controlling the assembly position of prefabricated column segments and ensure the firmness of the prefabricated column assembly nodes is a technical problem that technical personnel in this field urgently need to solve.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information is the prior art known to those skilled in the art.

DETAILED DESCRIPTION

[0046] The position control device and control method for assembling prefabricated column segments proposed in the present invention are further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer based on the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. For the convenience of description, the "upper" and "lower" mentioned below are consistent with the upper and lower directions of the accompanying drawings, but this cannot be a limitation of the technical solution of the present invention.

[0047] Example 1

[0048] 1 to 9 , the structural composition of the position control device for assembling prefabricated column segments of the present invention will be described in detail.

[0049] Please continue to refer to Figures 1 to 9, which show a position control device for assembling prefabricated column segments, used to splice the column 1 to be installed with the installed column 1. The position control device includes a self-controlled climbing wheel module 100, an outer frame body 200, a self-controlled locking module 300, a fixed clamping device 400 and a fixed locking connection unit 500.

[0050] Specifically, the self-controlled climbing wheel module 100 is mainly composed of a fixing structure, a driving structure and a locking structure. The fixed structure is made of high-strength steel material, including a high-strength connecting rod 101 and a side bracket 102, which are fastened by bolts to form a frame structure; the driving structure is a roller-type climbing module, whose structure is embedded in the side bracket 102, and the two ends of the extended transmission shaft 112 are respectively arranged in the gear set 113 and the anti-slip and explosion-proof wheel 111, and both ends are fixedly connected. The gear set 113 is arranged in the bearing seat through hole 103 and is connected to the anti-slip and explosion-proof wheel 111 through the extended transmission shaft 112. When the gear set 113 rotates, the anti-slip and explosion-proof wheel 111 is driven to rotate through the extended transmission shaft 112; the climbing wheel module motor 116 is arranged at the motor mounting hole 104 and is connected to the main gear 115; the main gear 115 is transmitted to the gear set 113 through the conveyor belt 114; the gear set 113, the conveyor belt 114, and the main gear 115 are all arranged on the inner side of the side bracket 102.

[0051] The locking structure includes a locking motor 121, a coupling 122, a high-strength threaded rod 123, a fixed support 124, and a support pin 125. One end of the coupling 122 is fixedly connected to the main shaft of the locking motor 121, and the other end of the coupling 122 is connected to the high-strength threaded rod 123. The fixed support 124 is fixedly mounted on the side wing bracket 102. The locking motor 121 and the fixed support 124 are mounted on different side wing brackets 102, and the high-strength threaded rod 123 is mounted inside the fixed support 124. When the locking motor 121 rotates, the high-strength threaded rod 123 rotates, pulling the opposite side wing bracket 102, completing the clamping of the automatic climbing wheel module 100. The high-strength threaded rod 123 plays the role of clamping or loosening the automatic climbing wheel module 100. The support pin 125 is arranged in the side wing bracket 102, one end of which is fixed in one side wing bracket 102, and the other end is embedded in the opposite side wing bracket and can move. When the clamping action of the automatic climbing wheel module 100 is completed, the support pin 125 bears the vertical force to prevent the side wing brackets 102 on both sides from breaking, thereby playing a connecting and strengthening role.

[0052] The outer frame body 200 is a rectangular frame structure 201 with pre-set holes 202 on the side, and its surface is provided with four rows of pre-set holes 202 with equal spacing. In other words, the inner frame tube frame 501 is provided with bolt holes 502 with the same number and spacing as the outer frame body 200 on the side, and high-strength locking bolts 503 are provided in the pre-set holes 202 and the bolt holes 502 to connect the inner frame tube frame 501 and the outer frame body 200. The outer frame body 200 is surrounded by lateral brackets 203 on the upper and lower sides. The lateral brackets 203 are used to support the circular guide rail frame 204. The circular guide rail frame 204 is a surrounding structure arranged on the lateral brackets 203, with one group arranged on the upper and lower sides; the magnetic track 205 is arranged on the circular guide rail frame 204, forming a circular surrounding structure. The outer frame body 200 is fixedly connected to the automatic climbing wheel module 100 above via a pair of connecting brackets 105.

[0053] The self-controlled locking module is a three-degree-of-freedom moving device. X-direction movement means moving forward and backward along the magnetic track 205, which is completed by the cooperation of the X-direction drive system 301 and the X-direction transmission slider 302. The X-direction drive system 301 is a travel system with a built-in motor drive system, which plays a leading role in movement. The X-direction transmission slider 302 is a supporting module. The X-direction drive system 301 is installed on different magnetic tracks 205 and can move along the magnetic track 205. The Y-direction movement means moving forward and backward along the axis direction of the Y-direction lead screw slide 304. The Y-direction drive motor 302 is installed on the Y-direction lead screw slide 304. 03 is located at the bottom of the Y-axis screw slide 304 and controls the rotation of the Y-axis screw. A slide seat 305 is installed on the Y-axis screw slide and is driven by the Y-axis screw. A Z-axis rotary motor 306 is installed on the slide seat 305. The Z-axis rotary motor 306 is connected to the spiral chuck 307 via a belt. The rotation of the Z-axis rotary motor 306 drives the spiral chuck 307 to rotate. The spiral locking wrench 308 is located inside the Z-axis rotary motor 306 and is connected to the spiral chuck 307. The rotation of the spiral chuck 307 can actuate the spiral locking wrench 308 to rotate forward. The Z-axis locking module of the automatic locking module can be set in two or more groups to improve locking efficiency. Here, the automatic locking module replaces the manual insertion of high-strength locking bolts into the bolt holes to complete the fixed connection between the fixed connection unit and the column connection node.

[0054] The fixed clamping device 400 is composed of a pneumatic control unit 401, a connecting arm section 402 and an L-shaped clamping assembly 403. The pneumatic control unit 401 controls the lateral movement of the connecting arm section 402, and the connecting arm section 402 is fixedly connected to the L-shaped clamping assembly 403; the pneumatic control unit 401 is fixedly connected to the outer frame body 200 through a high-strength bracket 404 arranged above it.

[0055] The locking connection unit 500 is used to lock the prefabricated column assembly structure. Its inner frame barrel 501 is made of high-strength steel and has bolt holes 502 on its side. The bolt holes 502 correspond one-to-one with the reserved holes 202 on the side of the outer frame. High-strength locking bolts 503 engage with the bolt holes 502. As the screw-type locking wrench 308 rotates and advances, it drives the high-strength locking bolts 503 into the bolt holes 502, eventually contacting the surface of the column 1, completing the fixed locking connection between the locking connection unit and the column connection node.
