Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a high-precision positioning and adjustment device for installing the guide seat of a building construction machine. Background Technology

[0002] With the technological development of building construction machines, more and more projects are gradually using them for construction. Various components in the construction process are becoming more mature. Embedded parts are connectors that are pre-installed inside concrete, walls, and other structures. Their core working principle is to transfer external loads from the auxiliary structure to the main structure through mechanical anchoring and structural force transmission, thereby achieving a reliable connection between the two and ensuring the stability and safety of the overall structure. As the core of its vertical load-bearing and guiding function, the installation accuracy of the guide seat directly determines the smoothness and safety of the entire building construction machine platform.

[0003] The installation process of a building construction machine can be roughly divided into: guide seat pre-embedding, column installation, steel platform truss installation, bracket installation, and auxiliary equipment installation. The high-precision positioning device for the guide seat installation of the building construction machine needs to provide accurate positioning benchmarks and stable force support for mechanical devices, equipment, or moving parts, and ensure that these parts can run smoothly along the preset trajectory and reliably transfer the load they generate to the main structure. In the existing technology, most of the pre-embedded parts are simply positioned and then the threaded sleeves are directly pre-embedded. The threaded sleeves will bear too much pressure after the guide seat is installed, and the distance distribution accuracy between the threaded sleeves is too low, which also affects the stress situation in the later stage.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-8 This invention provides a technical solution: a high-precision positioning and adjustment device for installing a guide seat on a building construction platform, comprising a shear key plate 1 and a sleeve frame 2. The shear key plate 1 is a steel plate and is slidably disposed on the inner wall of the sleeve frame 2. The sleeve frame 2 is provided with a slide rail that slides with the shear key plate 1 to restrict the shear key plate 1 to slide only in the horizontal direction. The shear key plate 1 is provided with a plurality of threaded sleeves 3, and a base plate 4 is fixed to the end of each threaded sleeve 3. A through hole is provided on the shear key plate 1 for the threaded sleeves 3 to pass through, and the threaded sleeves 3 pass through to one end of the shear key plate 1 and the base plate 4. The threaded sleeve 3 is connected by welding. A locator for accurately positioning the base plate 4 is provided on the front side of the threaded sleeve 3. A gasket 5 is placed between the threaded sleeve 3 and the locator. The locator includes a fastening bolt 6, a washer 7, a handle 8, and a perforated steel plate 9. The perforated steel plate 9 is frame-shaped. The handle 8 is fixed to the top of the perforated steel plate 9, which is located in front of the gasket 5. The perforated steel plate 9 and the handle 8 are welded together. The perforated steel plate 9 has an opening for the bolt to pass through. The fastening bolt 6 is located inside the threaded sleeve 3, and the two are threaded together. The washer 7 is located between the perforated steel plate 9 and the handle 8. Between the fastening bolts 6, a washer 5 is placed between the perforated steel plate 9 and the threaded sleeve 3. An adjusting screw 10 is provided between the sleeve frame 2 and the shear key plate 1. By setting a locator, before pouring concrete, the user opens a through hole at the corresponding position on the shear key plate 1, passes the threaded sleeve 3 through it, welds the threaded sleeve 3 to the base plate 4, and then opens the corresponding position on the perforated steel plate 9. After aligning the through hole and the opening, a washer 5 is installed between the perforated steel plate 9 and the threaded sleeve 3, and a washer 7 is installed on the fastening bolts 6. The bolts are then passed through the washer 7 and the perforated steel plate 6 in sequence. After steel plate 9 and shim 5, fastening bolt 6 and threaded sleeve 3 are threaded together to form an integral embedded part for the installation of the building machine guide seat. The sleeve frame 2 and shear key plate 1 are fixed in the preset position of the concrete skeleton. By fine-tuning the adjusting screw 10, the horizontal position of the base plate 4 is adjusted so that the adjacent base plates 4 in the vertical direction maintain the same vertical axis, which facilitates the subsequent installation of guide seat and column. The embedded combination of shear key plate 1 and concrete provides strong shear bearing capacity and can effectively resist the horizontal force and vibration generated during the operation of the building machine.

[0031] Reference Figures 1-8A centering mechanism is provided on the shear key plate 1. The centering mechanism includes a mounting plate 1101, which is fixed to the shear key plate 1 by bolts. An upper receiving block 1102 and a lower receiving block 1103 are integrally formed on the top and bottom of the mounting plate 1101, respectively. A centering groove 1104 is formed on the top of the upper receiving block 1102, and the centering groove 1104 is funnel-shaped. A probe 1105 is slidably provided on the bottom of the lower receiving block 1103. A connecting rod 1106 is provided above the centering groove 1104. An insert block 1107 adapted to the centering groove 1104 is provided at the bottom of the connecting rod 1106, and a matching groove 1108 of the same shape as the centering groove 1104 is provided at the top of the connecting rod 1106. By setting up the centering mechanism, the user can position the frame 2... After the base plate 4 is installed onto the concrete frame, the bottom base plate 4 is adjusted to the preset position. Then, the mounting plate 1101 is installed on the shear key plate 1 with bolts. At this time, the centering groove 1104 corresponds to the center axis position of the subsequent guide seat. The splicing rod 1106 is installed on the bottom upper receiving block 1102 with bolts. The splicing rods 1106 are spliced ​​one by one with bolts until the position of the top splicing rod 1106 is close to the upper sleeve 2 and the base plate 4. The position of the upper base plate 4 is adjusted by turning the adjusting screw 10 until the probe 1105 of the upper lower receiving block 1103 falls into the vertical section of the lower centering groove 1104. This indicates that the upper threaded sleeve 3 and the lower threaded sleeve 3 are aligned, thus achieving the alignment of the subsequent guide seat installation.

[0032] Reference Figures 1-8A first spring seat 1109 is fixedly mounted on the inner bottom wall of the lower receiving block 1103. A probe 1105 is slidably disposed inside the first spring seat 1109. A first reset plate 1110 is fixedly mounted on the surface of the probe 1105. A first reset spring 1111 and a first telescopic rod are disposed between the first reset plate 1110 and the first spring seat 1109. A turntable 1112 is rotatably mounted on the inner wall of the lower receiving block 1103. A first connecting rod 1113 is disposed between the probe 1105 and the turntable 1112. One end of the first connecting rod 1113 is hinged to the rear side of the turntable 1112, and the other end of the first connecting rod 1113 is hinged to the probe 1105. A support frame 111 is fixedly mounted on the inner wall of the lower receiving block 1103 by bolts and a mounting plate. 4. A ratchet 1115 is rotatably mounted on the support frame 1114 via a one-way bearing. A disc 1116 is rotatably mounted coaxially on the inner side of the ratchet 1115. A pawl 1117 is rotatably mounted on the disc 1116. The ratchet 1115 and the pawl 1117 intermittently mesh. A first torsion spring is provided between the pawl 1117 and the disc 1116. A gear 1118 is rotatably mounted on the inner wall of the lower receiving block 1103. A coupling rod 1119 is fixed between the gear 1118 and the disc 1116. A gear ring 1120 is coaxially fixed on the surface of the turntable 1112. The gear 1118 and the gear ring 1120 mesh. By setting the ratchet 1115 and the pawl 1117, when the upper probe 1105 has not yet engaged with the lower centering groove 1104... During alignment, the probe 1105 is lifted by the top wall of the upper receiving block 1102 or the inclined section of the alignment groove 1104, compressing the first return spring 1111. The probe 1105 moves upward, and with the cooperation of the first connecting rod 1113, the turntable 1112 drives the gear ring 1120 to rotate. Through the meshing connection between the gear ring 1120 and the gear 1118, the gear 1118 drives the coupling rod 1119 to rotate. The coupling rod 1119 drives the disc 1116 and the pawl 1117 to rotate. At this time, the pawl 1117 and the ratchet teeth on the ratchet wheel 1115 are pressed together. Since the ratchet wheel 1115 can only rotate in one direction, it does not rotate. The pawl 1117 rotates itself, and the first torsion spring is compressed. The probe 1105 retracts until the pawl 1117 and the ratchet tooth intersect. Then, the first torsion spring and the pawl 1117 return to their original positions and continue to press against the next ratchet tooth. This process is repeated until the probe 1105 is aligned with the centering groove 1104. Under the rebound force of the first return spring 1111, the probe 1105 moves rapidly downward. At this time, the turntable 1112 rotates in the opposite direction, thereby driving the disc 1116 and the pawl 1117 to rotate in the opposite direction. At this time, the pawl 1117 and the ratchet tooth on the ratchet 1115 abut against each other, thereby driving the ratchet 1115 to rotate. With the cooperation of the elastic fork 1132 and the tuning fork 1129, a knocking sound is emitted to remind the user, thus avoiding the problem that the user cannot see with the naked eye whether the probe 1105 is inserted into the centering groove 1104.

[0033] Reference Figures 1-8A second spring seat 1121 is fixedly provided on the inner bottom wall of the lower receiving block 1103. A second return spring 1122 and a second telescopic rod are provided on the second spring seat 1121. A second return plate 1123 is provided at the other end of the second return spring 1122 and the second telescopic rod. A rotating plate 1124 is rotatably provided on the inner wall of the support frame 1114. A second torsion spring is provided between the rotating plate 1124 and the support frame 1114. A second connecting rod 1125 is provided between the rotating plate 1124 and the second return plate 1123. One end of the second connecting rod 1125 is hinged to the rotating plate 1124, and the other end of the second connecting rod 1125 is hinged to the second return plate 1123. A fixing plate 1126 is fixedly provided on the inner wall of the support frame 1114. The fixing plate 1126 and the rotating plate 1124 are connected. The mounting plate 1126 is coaxially arranged with several limiting grooves 1127. A limiting block 1128 is slidably disposed inside each limiting groove 1127. A tuning fork 1129 is fixedly disposed on each limiting block 1128. The rotating plate 1124 has several arc-shaped grooves 1130, the number of which is the same as the limiting grooves 1127. A sliding shaft 1131 is slidably disposed inside each arc-shaped groove 1130. The sliding shaft 1131 is fixedly connected to the limiting block 1128. An elastic fork 1132 is fixedly disposed on the surface of the ratchet 1115. A third return spring 1133 is disposed at the bottom of the lower receiving block 1103. A top plate 1134 is disposed at the other end of the third return spring 1133. A top rod 1135 is fixedly disposed at the top of the top plate 1134. The second return plate 112... A drive rod 1136 is provided at the bottom of component 3. The distance between the top rod 1135 and the drive rod 1136 is the same as the length of the vertical section of the centering groove 1104. By setting a rotating plate 1124 and a fixed plate 1126, when the probe 1105 is not aligned due to being squeezed by the top wall of the upper receiving block 1102 or the inclined end of the centering groove 1104, the probe 1105 moves upward, causing the top plate 1134 to move upward, so that the top rod 1135 squeezes the drive rod 1136. When the drive rod 1136 moves upward, the rotating plate 1124 rotates through the cooperation of the second connecting rod 1125, and the inner wall of the arc groove 1130 squeezes the sliding shaft 1131. Under the limiting cooperation of the limiting groove 1127, the limiting block 1128 drives the tuning fork 112. 9 moves radially away from the center of the rotating plate 1124. At this time, the elastic fork 1132 and the tuning fork 1129 are misaligned, meaning the tuning fork 1129 is not on the rotation trajectory of the elastic fork 1132. Simultaneously, with the cooperation of the ratchet 1115 and the pawl 1117, the ratchet 1115 does not rotate the elastic fork 1132. When the user moves the probe 1105 by turning the adjusting screw 10, the probe 1105 moves horizontally on the upper receiving block 1102, but does not move vertically. The ratchet 1115 does not rotate the elastic fork 1132. When the probe 1105 moves along the inclined section of the central groove 1104, it moves slightly downwards.Ratchet 1115 drives the flexible fork 1132 to rotate. However, at this time, probe 1105 can only drive the push rod 1135 to move slightly downward. Since the flexible fork 1132 is still misaligned with the tuning fork 1129, the tuning fork 1129 cannot produce sound until probe 1105 is fully aligned. At this time, probe 1105 descends rapidly, thus releasing the restriction on push rod 1135. Push rod 1135 no longer abuts against drive rod 1136, and rotating plate 1124 returns to its original position through the rebound force of the second torsion spring. At this time, tuning fork 1129 returns to its original position, located on the rotation trajectory of flexible fork 1132. Simultaneously, the rotation of ratchet 1115 drives the flexible fork 1132 to rotate, and flexible fork 1132 strikes each tuning fork 1129, thus producing a sound to indicate to the user that alignment is complete.

[0034] Specifically, the working process or principle of this high-precision positioning and adjustment device for the guide seat installation of a building construction machine is as follows: Before concrete pouring, the user opens a through hole at the corresponding position of the shear key plate 1, passes the threaded sleeve 3 through it, and welds the threaded sleeve 3 to the base plate 4. Then, after opening the corresponding position of the perforated steel plate 9, align the through hole and the opening, add a shim 5 between the perforated steel plate 9 and the threaded sleeve 3, and add a washer 7 to the fastening bolt 6. The bolt is then passed through the washer 7, the perforated steel plate 9, and the shim 5 in sequence. Finally, the fastening bolt 6 and the threaded sleeve 3 are threaded together, forming a complete embedded part for the building construction machine guide seat installation. The bottom plate 4 is then adjusted to the preset position. The mounting plate 1101 is bolted onto the shear key plate 1. At this time, the centering groove 1104 corresponds to the central axis position of the subsequent guide seat. The splicing rod 1106 is bolted onto the lowermost upper receiving block 1102, and the splicing rods 1106 are sequentially spliced ​​together with bolts until the uppermost splicing rod 1106 is close to the upper sleeve 2 and the base plate 4. The position of the upper base plate 4 is adjusted by turning the adjusting screw 10. When the upper probe 1105 has not yet aligned with the lower centering groove 1104, the probe 1105 is lifted by the top wall of the upper receiving block 1102, the first return spring 1111 is compressed, and the probe 1105 moves upward. With the cooperation of the first connecting rod 1113, the turntable 1112 drives the gear ring 112. When the probe 1105 rotates, the meshing connection between the gear ring 1120 and the gear 1118 causes the gear 1118 to drive the coupling rod 1119 to rotate. The coupling rod 1119 then drives the disc 1116 and the pawl 1117 to rotate. At this time, the pawl 1117 and the ratchet on the ratchet wheel 1115 are pressed together. Since the ratchet wheel 1115 can only rotate in one direction, it does not rotate. The pawl 1117 rotates on its own, and the first torsion spring is compressed until the pawl 1117 and the ratchet intersect. Then, the first torsion spring and the pawl 1117 return to their original positions and continue to press against the next ratchet. This process repeats. At the same time, if the probe 1105 is not aligned due to being pressed against the top wall of the upper receiving block 1102 or the inclined end of the centering groove 1104, the probe 1105 moves upward, driving the top... Plate 1134 moves upward, causing push rod 1135 to press against drive rod 1136. When drive rod 1136 moves upward, through the cooperation of second connecting rod 1125, rotating plate 1124 rotates. The inner wall of arc groove 1130 presses against sliding shaft 1131. Under the limiting cooperation of limiting groove 1127, limiting block 1128 drives tuning fork 1129 to move radially away from the center of rotating plate 1124. At this time, elastic fork 1132 is misaligned with tuning fork 1129, that is, tuning fork 1129 is not on the rotation trajectory of elastic fork 1132. By fine-tuning adjusting screw 10, the horizontal position of base plate 4 is adjusted. When probe 1105 moves on the inclined section of middle groove 1104...At this point, probe 1105 moves slightly downward, and ratchet 1115 drives the elastic fork 1132 to rotate. However, probe 1105 can only drive push rod 1135 to move slightly downward. Since the elastic fork 1132 is still misaligned with tuning fork 1129, tuning fork 1129 cannot produce sound until probe 1105 is fully aligned. At this point, probe 1105 descends rapidly, thus releasing the restriction on push rod 1135. Push rod 1135 no longer abuts against drive rod 1136, and the rotating plate... 1124 returns to its original position due to the rebound force of the second torsion spring. At this time, the tuning fork 1129 also returns to its original position, located on the rotation trajectory of the elastic fork 1132. The turntable 1112 then rotates in the opposite direction, thereby causing the disc 1116 and the pawl 1117 to rotate in the opposite direction. The pawl 1117 then abuts against the ratchet teeth on the ratchet 1115, causing the ratchet 1115 to rotate. Through the cooperation of the elastic fork 1132 and the tuning fork 1129, a striking sound is emitted to remind the user.
