Description

Technical Field

[0001] This invention belongs to the field of building construction machine technology, specifically relating to a truss platform for a building construction machine. Background Technology

[0002] Building construction machines are core equipment for intelligent building construction, possessing advantages such as overall climbing, synchronous operation, and enclosed construction. They are widely used in the construction of high-rise and super high-rise buildings, effectively improving the level of construction mechanization, shortening the construction period, and reducing the risks of high-altitude operations. The truss platform is the core load-bearing structure of the building construction machine, and its assembly efficiency and construction economy directly affect the construction efficiency and applicable scope of the machine.

[0003] Existing truss platforms for building construction machines generally adopt a fully bolted assembly structure, with each member and node secured by a large number of bolts. While this structure can meet basic load-bearing and stability requirements, it has significant technical drawbacks: a large number of bolted connections, cumbersome assembly procedures, requiring on-site alignment, tightening, and verification, resulting in time-consuming assembly, high labor input, and low construction efficiency. For high-rise and super high-rise buildings, with long construction cycles and numerous truss machine cycles, the time saved by the equipment can cover the platform assembly time, leading to good overall benefits. However, for mid- to high-rise buildings with fewer floors and shorter construction cycles, the effective number of truss machine operations is limited, and the time spent assembling the truss platform far exceeds the time saved by the equipment, significantly increasing construction costs. This results in extremely poor economic efficiency for truss machines in mid- to high-rise building construction, severely limiting their applicability.

[0004] To address the problem of low assembly efficiency in the existing all-bolted assembly method of building machine truss platforms, this invention optimizes and improves the assembly method of truss platforms, simplifying the assembly process and shortening the assembly time. Summary of the Invention

[0005] This invention aims to solve the problems of existing building machine truss platforms that use a fully bolted assembly method, which have many nodes and are cumbersome and time-consuming to assemble.

[0006] The present invention provides the following technical solution: a truss platform for a building construction machine, comprising long main truss segments and short cross braces, wherein every two long main truss segments are connected to two short cross braces to form a truss segment unit, and several truss segment units are assembled into a truss platform; The short cross brace and the long main truss are connected by a horizontal tensioning device. The horizontal tensioning device includes a fixed part in the middle and a tie rod mechanism connected to both sides of the fixed part. The fixed part is fixedly connected to the chord of the short cross brace, and the tie rod mechanism tightens the chord of the long main truss on both sides. The two truss segments are connected by a locking device, which includes a U-shaped locking rod and a locking body. The U-shaped locking rod is inserted into the two chords that are in contact with each other, and the locking body is connected to the U-shaped locking rod to clamp and fix the two chords.

[0007] Furthermore, the fixing part of the cross-pull device includes an inner slide frame, and an adjustment module is provided in the middle of the inner slide frame; The lever mechanism includes a lever, a slider, an upper rack, and a lower rack. Two sliders are slidably nested in the inner slide frame. The upper rack and the lower rack are slidably attached to the top and bottom surfaces of the inner slide frame, respectively. Each of the upper rack and the lower rack is fixedly connected to a slider. Two levers extend into the inner slide frame from both sides and are connected to a slider. The boss at the outer end of the lever can stop in the insertion hole on the chord. The adjustment module includes a support box, a first gear, and a first limiting cover. The first gear is rotatably mounted in the support box and meshes with the upper and lower racks. A first torque input interface is provided at the center of one end face of the first gear, and the first torque input interface protrudes from the support box. First positioning holes are evenly distributed on the circumference of the support box coaxial with the first gear. A first locking post is provided at the center of the first limiting cover, which matches the first torque input interface of the first gear. First pins are distributed around the first locking post on the first limiting cover, corresponding one-to-one with the first positioning holes on the support box.

[0008] Furthermore, the slider has a lock hole, and locking plates are slidably inserted into both sides of the lock hole. A spring connects the locking plates to the slider, and a pull rope is connected to the locking plates. The pull rope passes through the wire hole in the slider and is connected to the take-up reel. The rotation handle of the take-up reel extends out from the slider. The end of the pull rod that connects to the slider is a cone with a groove around it. The pull rod is inserted into the locking hole of the slider, and the locking plate is engaged in the groove.

[0009] Furthermore, a secondary rack is provided on the side of the upper rack, and a second gear is rotatably installed inside the support box. The second gear meshes with the secondary rack, and the gear shaft of the second gear protrudes from the support box. A second torque input interface is provided at the center of the end face of the gear shaft. Second positioning holes are evenly distributed on the circumference of the support box coaxial with the second gear. The adjustment module also includes a second limiting cover. The center of the second limiting cover is provided with a second locking post that matches the second torque input interface of the second gear. The second limiting cover is surrounded by second pins that correspond one-to-one with the second positioning holes on the support box.

[0010] Furthermore, the locking body of the locking device includes a stop block with two insertion interfaces corresponding to the straight rod of the U-shaped locking rod. Locking teeth are slidably inserted into the top surface of the insertion interfaces on the stop block, and the locking teeth are connected to the spring pushing mechanism inside the stop block. The top surface of the straight rod of the U-shaped locking rod has locking tooth grooves distributed along its length. The straight rod of the U-shaped locking rod is inserted into the insertion interface of the stop block, and the locking teeth and locking tooth grooves engage to lock the U-shaped locking rod.

[0011] Furthermore, the spring pushing mechanism includes two guide rods. The stop block has elongated holes on both sides of the locking teeth. The guide rods are located in the elongated holes and are slidably supported by the limiting plates in the elongated holes. A pushing plate is fixedly connected to the guide rod between the two limiting plates. A return spring is sleeved on the guide rod between the pushing plate and the upper limiting plate. The two guide rods are connected to the locking teeth, and a handle is connected between the top ends of the two guide rods.

[0012] Furthermore, the locking device also includes two sets of fixed support assemblies, which are fixed on opposite sides of the chord. The fixed support assembly includes a support plate, which is fixedly connected to the chord. The support plate has a square hole that allows the stop block to pass through. A baffle that can enter and exit from the square hole is connected to the support plate. The stop block has a positioning groove corresponding to the baffle.

[0013] Furthermore, the support plate is provided with rails on both sides, and a slide bar frame is erected at the end of the rail. A slide seat is slidably clamped on the rail, and a slide bar fixedly connected to the slide seat is movably inserted into the slide bar frame. A tension spring is connected between the slide seat and the slide bar frame, and the tension spring is sleeved on the slide bar. A horizontal plate is connected between the slide seats on both sides, and a baffle is fixed on the horizontal plate.

[0014] Furthermore, a guide rod extends from the support plate, parallel to the rail, and the cross plate is slidably sleeved on the guide rod.

[0015] Furthermore, the support plate and the chord are connected by bolts.

[0016] Compared with the prior art, the advantages of the present invention are: The present invention provides a truss platform for a building construction machine, which realizes the rapid connection between short cross braces and long main truss segments through a horizontal tensioning device and the rapid docking between truss segment units through a locking device, replacing the tedious process of aligning, tightening and verifying a large number of bolts one by one in the traditional all-bolt assembly method.

[0017] In the lateral tensioning device, the operator only needs to pass the tie rod through the insertion hole of the chord and insert it into the locking hole of the slider. The locking plate in the locking hole engages with the groove of the tie rod to complete the quick assembly of the tie rod and the slider. Subsequently, through the meshing transmission of the first gear and the upper and lower racks, rotating the first gear will synchronously drive the sliders on both sides to move in opposite directions, thereby driving the tie rods on both sides to tighten the chord of the long main truss, realizing the quick tightening and fixing of the short cross brace to the long main truss on both sides. The entire operation process does not require tightening bolts at each connection point individually, greatly reducing the operation time for a single connection.

[0018] In the locking device, the U-shaped locking rod is inserted into the insertion interface of the stop block after being inserted into the chord of the two truss segment units that are close to each other. The locking teeth automatically engage with the locking tooth groove under the action of the spring pushing mechanism, realizing the rapid locking of the two truss segment units without having to insert bolts and tighten nuts one by one.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] like Figure 2 , Figure 3 As shown: A truss platform for a building construction machine includes long main truss segments 1 and short cross braces 2. Every two long main truss segments 1 and two short cross braces 2 are connected to form a truss segment unit 3. Several truss segment units 3 are assembled into a truss platform.

[0023] like Figure 1 , Figure 2 As shown: The lower part of the truss platform is connected to the lifting mechanism 8, which lifts and supports the truss platform. A platform walkway 6 and guardrail 7 are installed on the upper part of the truss platform, and external protection 10 is installed around the perimeter of the truss platform. (This part is the existing structure of the building construction machine.) The long main truss 1 consists of two upper and lower long main truss chords 1.1 and a middle web member (including vertical web members and diagonal web members), and the members are welded together. The short cross brace 2 consists of three upper, middle and lower short cross brace chords 2.1 and a web member (including vertical web members and diagonal web members) connecting the three, and the members are also welded together.

[0024] like Figure 4 As shown: The short cross brace 2 and the long main truss 1 are connected by a horizontal tensioning device 4. The horizontal tensioning device 4 includes a fixed part in the middle and a tie rod mechanism connected to both sides of the fixed part. The fixed part is fixedly connected to the chord of the short cross brace 2, and the tie rod mechanism tightens the chord of the long main truss 1 on both sides.

[0025] Specifically, a horizontal tensioning device 4 is fixedly connected to the upper and lower short cross brace chords 2.1 of the short cross brace 2. The horizontal tensioning device 4 tightens and fixes the upper and lower long main truss chords 1.1 of the long main truss 1.

[0026] The two truss segment units 3 are connected by a locking device 5, which includes a U-shaped locking rod 5.1 and a locking body. The U-shaped locking rod 5.1 is inserted into the two chords of the two truss segment units 3 that are in contact with each other. The locking body is connected to the U-shaped locking rod 5.1 to clamp and fix the two chords.

[0027] The two truss segment units are divided into end-to-end connections and perpendicular connections; Two truss segment units 3 are connected end to end, and their short cross braces 2 are connected. The locking device 5 clamps and fixes the short cross brace chord 2.1 between the two short cross braces 2. Two truss segment units 3 are vertically connected. The short cross brace 2 of one truss segment unit 3 is connected to the long main truss segment 1 of the other truss segment unit 3. The upper and lower short cross brace chords 2.1 of the short cross brace 2 are clamped and fixed to the upper and lower long main truss chords 1.1 of the long main truss segment 1 respectively by locking device 5. The locking device 5 also fixes the cross tension device 4 on the upper and lower short cross brace chords 2.1 inside. The locking device 5 is located on the fixing part of the cross tension device 4.

[0028] like Figure 5 , Figure 6 , Figure 7 As shown: The fixing part of the horizontal bracing device 4 includes an inner sliding frame 4.1, which is fixed on the short horizontal bracing chord 2.1 of the short horizontal bracing 2. It is connected to the bolt holes on the short horizontal bracing chord 2.1 by bolts at the four corners. An adjustment module is set in the middle of the inner sliding frame 4.1. The adjustment module controls the tensioning mechanism to tighten or loosen the long main truss 1 on both sides.

[0029] The linkage mechanism includes a linkage 4.2, a slider 4.3, an upper rack 4.4, and a lower rack 4.5. Two sliders 4.3 are slidably nested in the inner slide frame 4.1. The upper rack 4.4 and the lower rack 4.5 are slidably attached to the top and bottom surfaces of the inner slide frame 4.1, respectively. Each of the upper rack 4.4 and the lower rack 4.5 is fixedly connected to one slider 4.3. Two linkages 4.2 extend into the inner slide frame 4.1 from both sides and are connected to one slider 4.3. The boss 4.2.1 on the outer end of the linkage 4.2 can stop in the insertion hole on the chord. The linkage 4.2 is inserted into the insertion hole of the long main truss chord 1.1 and connected to the slider 4.3. The slider 4.3 drives the linkage 4.2 to move, and the boss 4.2.1 on the linkage 4.2 pulls the long main truss chord 1.1.

[0030] A washer 4.2.2 is fitted on the tie rod 4.2. The washer 4.2.2 is placed between the boss 4.2.1 and the long main stringer chord 1.1. The washer 4.2.2 serves as a force transmission component between the boss 4.2.1 and the long main stringer chord 1.1. If the pressure is too high, the washer 4.2.2 will be damaged first. The washer 4.2.2 can be replaced separately, which reduces maintenance costs.

[0031] The adjustment module includes a support box 4.6, a first gear 4.7, and a first limiting cover 4.8. The first gear 4.7 is rotatably mounted in the support box 4.6 and meshes with the upper rack 4.4 and the lower rack 4.5. A first torque input interface 4.7.1 is provided at the center of one end face of the first gear 4.7, which protrudes from the support box 4.6. Torque is applied to the first gear 4.7 through the first torque input interface 4.7.1. When the first gear 4.7 rotates, the upper rack 4.4 and the lower rack 4.5 that mesh with it move in opposite directions, driving the slider 4.3 and the pull rod 4.2 to move. The first torque input interface 4.7.1 is an internal hexagonal hole, and the first gear 4.7 is rotated by an internal hexagonal wrench. The support box 4.6 has first positioning holes 4.6.1 evenly distributed on its circumference, which is coaxial with the first gear 4.7. The center of the first limiting cover 4.8 is provided with a first locking pin 4.8.1 that matches the first torque input interface 4.7.1 of the first gear 4.7. The first limiting cover 4.8 has first pins 4.8.2 distributed around the first locking pin 4.8.1, which correspond one-to-one with the first positioning holes 4.6.1 on the support box 4.6. The first gear 4.7 cannot self-lock with the upper rack 4.4 and the lower rack 4.5. The pull rod 4.2, under the counter-thrust of the long main beam 1, will drive the upper rack 4.4 or the lower rack 4.5 to move in the opposite direction, causing the first gear 4.7 to reverse. The first gear 4.7 is locked by the first limiting cover 4.8. The first locking pin 4.8.1 on the first limiting cover 4.8 is inserted into the first torque input interface 4.7.1 to fix the first limiting cover 4.8 and the first gear 4.7 circumferentially. The first pin 4.8.2 on the first limiting cover 4.8 is inserted into the first positioning hole 4.6.1 on the support box 4.6. The first limiting cover 4.8 cannot rotate relative to the support box 4.6, thereby restricting the rotation of the first gear 4.7.

[0032] like Figure 7As shown: A secondary rack 4.4.1 is provided on the side of the upper rack 4.4. A second gear 4.9 is rotatably mounted inside the support box 4.6. The second gear 4.9 meshes with the secondary rack 4.4.1. The gear shaft of the second gear 4.9 protrudes from the support box 4.6, and a second torque input interface 4.9.1 is provided at the center of the end face of the gear shaft. Second positioning holes 4.6.2 are evenly distributed on the circumference of the support box 4.6, coaxial with the second gear 4.9. Torque is applied to the second gear 4.9 through the second torque input interface 4.9.1. When the second gear 4.9 rotates, it drives the upper rack 4.4 to move. The upper rack 4.4 drives the first gear 4.7 to rotate, and then the lower rack 4.5 follows suit. The second torque input interface 4.9.1 serves as a backup torque input port. When there is interference at the first torque input interface 4.7.1, making operation inconvenient, torque is input through the second torque input interface 4.9.1. The second torque input interface 4.9.1 is also an internal hexagonal port.

[0033] The adjustment module also includes a second limiting cover 4.10. The center of the second limiting cover 4.10 has a second locking pin 4.10.1 that matches the second torque input interface 4.9.1 of the second gear 4.9. Around the second locking pin 4.10.1, second pins 4.10.2 are distributed on the second limiting cover 4.10, corresponding one-to-one with the second positioning holes 4.6.2 on the support box 4.6. The working mechanism of the second limiting cover 4.10 is the same as that of the first limiting cover 4.8. It should be noted that regardless of whether the torque is input through the first torque input interface 4.7.1 or the second torque input interface 4.9.1, both the first limiting cover 4.8 and the second limiting cover 4.10 must be removed.

[0034] An anti-loss rope 4.11 is connected between the first limiting cover 4.8, the second limiting cover 4.10, and the support box 4.6.

[0035] like Figure 8 , Figure 9 As shown: A locking hole 4.3.1 is opened on the slider 4.3. Locking plates 4.3.2 are slidably inserted into the slider 4.3 on both sides of the locking hole 4.3.1. A spring 4.3.3 is connected between the locking plates 4.3.2 and the slider 4.3. The spring 4.3.3 pushes the locking plates 4.3.2 towards the center of the locking hole 4.3.1. A sliding limit is set between the locking plates 4.3.2 and the slider 4.3 to prevent the locking plates 4.3.2 from completely disengaging. A pull rope 4.3.4 is connected to the locking plates 4.3.2. The pull rope 4.3.4 passes through the threading hole 4.3.5 in the slider 4.3 and connects to the take-up reel 4.3.6. The rotating handle 4.3.7 of the take-up reel 4.3.6 extends out from the slider 4.3.

[0036] The end of the pull rod 4.2 connected to the slider 4.3 is tapered and has a groove. The pull rod 4.2 is inserted into the locking hole 4.3.1 of the slider 4.3, and the locking plate 4.3.2 is engaged in the groove. When the pull rod 4.2 is inserted into the locking hole 4.3.1, the tapered end of the pull rod 4.2 pushes the locking plate 4.3.2 open, and then the locking plate 4.3.2 engages in the groove, completing the quick connection between the pull rod 4.2 and the slider 4.3. When the handle 4.3.7 is turned to rotate the take-up reel 4.3.6, the take-up reel 4.3.6 winds up the pull rope 4.3.4, and the pull rope 4.3.4 pulls the locking plate 4.3.2 out of the locking hole 4.3.1, releasing the lock on the pull rod 4.2.

[0037] like Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown: The locking body of the locking device 5 includes a stop block 5.2. The stop block 5.2 has two insertion interfaces 5.2.1 corresponding to the straight rods of the U-shaped locking rod 5.1. Locking teeth 5.2.2 are slidably inserted into the top surface of the insertion interfaces 5.2.1 on the stop block 5.2. The locking teeth 5.2.2 are connected to the spring pushing mechanism inside the stop block 5.2. The top surface of the straight rod of the U-shaped locking rod 5.1 has locking tooth grooves 5.1.1 distributed along the length direction. The straight rod of the U-shaped locking rod 5.1 is inserted into the insertion interface 5.2.1 of the stop block 5.2. The locking teeth 5.2.2 and the locking tooth grooves 5.1.1 engage to lock the U-shaped locking rod 5.1.

[0038] The U-shaped locking rod 5.1 is fitted onto the two chords, and then the stop block 5.2 is inserted into the U-shaped locking rod 5.1. The stop block 5.2, together with the U-shaped locking rod 5.1, clamps and fixes the two chords.

[0039] The spring-pushing mechanism provides a thrust that engages the locking teeth 5.2.2 with the locking tooth groove 5.1.1. The spring-pushing mechanism includes two guide rods 5.3. The stop block 5.2 has elongated holes on both sides of the locking teeth 5.2.2. The guide rods 5.3 are located in the elongated holes and are slidably supported by the limiting plates 5.3.1 in the elongated holes. A push plate 5.3.2 is fixedly connected to the guide rods 5.3 between the two limiting plates 5.3.1. A return spring 5.3.3 is sleeved on the guide rods 5.3 between the push plate 5.3.2 and the upper limiting plate 5.3.1. The two guide rods 5.3 are connected to the locking teeth 5.2.2. A handle 5.3.4 is connected between the top ends of the two guide rods 5.3. The return spring 5.3.3 pushes the guide rod 5.3 downward, and the guide rod 5.3 moves downward with the locking tooth 5.2.2, while the locking tooth 5.2.2 remains engaged in the locking tooth groove 5.1.1; the guide rod 5.3 is lifted upward by the handle 5.3.4, and the guide rod 5.3, along with the locking tooth 5.2.2, exits from the locking tooth groove 5.1.1, releasing the lock between the stop block 5.2 and the U-shaped locking rod 5.1.

[0040] like Figure 10 , Figure 12 , Figure 13 As shown: The locking device 5 also includes two sets of fixed support components, which are fixed on opposite sides of the chord. The fixed support assembly includes a support plate 5.4, which is fixedly connected to the chord by bolts. The support plate 5.4 has a square hole 5.4.1 that allows the stop block 5.2 to pass through. A baffle 5.5 that can move in and out of the square hole 5.4.1 is connected to the support plate 5.4. The stop block 5.2 has a positioning groove 5.2.3 that corresponds to the baffle 5.5. After the stop block 5.2 is inserted into the support plate 5.4, the baffle 5.5 engages with the positioning groove 5.2.3 on the stop block 5.2, locking the stop block 5.2.

[0041] When installing the locking device 5, first fix the two support plates 5.4 onto the same chord, then insert the stop block 5.2 into the two support plates 5.4, and finally insert the U-shaped locking rod 5.1 onto the two chords, with the U-shaped locking rod 5.1 inserted into the stop block 5.2. The locking device 5 is restricted from moving laterally along the chord by fixing the support assembly.

[0042] The support plate 5.4 has rails 5.6 on both sides, and a slide bar frame 5.6.1 is erected at the end of the rails 5.6. A sliding seat 5.7 is slidably clamped on the rails 5.6. A slide bar 5.8, which is fixedly connected to the sliding seat 5.7, is movably inserted into the slide bar frame 5.6.1. A tension spring 5.9 connects the sliding seat 5.7 and the slide bar frame 5.6.1, and the tension spring 5.9 is sleeved on the slide bar 5.8. A horizontal plate 5.10 connects the two sliding seats 5.7, and a baffle 5.5 is fixed on the horizontal plate 5.10. The tension spring 5.9 pulls the sliding seat 5.7, causing the sliding seat 5.7 to move closer to the slide bar frame 5.6.1. The sliding seat 5.7 moves along with the horizontal plate 5.10 and the baffle 5.5, and the baffle 5.5 maintains its tendency to be inserted into the positioning groove 5.2.3 of the stop block 5.2.

[0043] A guide rod 5.11 extends from the support plate 5.4 and is parallel to the rail 5.6. A cross plate 5.10 is slidably sleeved on the guide rod 5.11; the guide rod 5.11 guides and supports the cross plate 5.10.
