Cradle structure for truss assembly

Abstract

The present invention discloses a truss assembly frame structure. The structure utilizes the weight of the rods and other components of a tube truss to press down a support plate to rotate a turntable, causing the upper rod of the turntable to push against a push rod, which in turn causes the push rod upper pressure plate to lock the rod. This ensures a secure and stable installation of the tube truss rods, thereby improving the precision of the tube truss assembly. Furthermore, by raising the jacking member and locking the locking member, the height of the support plate of the pedestal is locked after adjusting the setting height, further improving the stability of the tube truss assembly and making it suitable for the assembly of tube trusses of various specifications. The present invention solves the problem that existing triangular tube truss frames are mainly fixed structures and difficult to adjust in height.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Reference Figures 1 to 3 As shown, the present invention provides a truss frame structure for assembling trusses, comprising: a base 1, a bearing platform 2, a self-locking structure 3, a locking assembly and a driving mechanism.

[0032] The base and the support are cylindrical. The outer diameters of the base and the support are compatible. Figure 3 As shown, a socket hole 10 is provided on the top of the base 1. The socket hole is arranged on the central axis of the base.

[0033] A lifting member 21 is installed at the bottom of the support platform 2. The lower end of the lifting member 21 is movably supported on the top of the base 1. In this embodiment, the lifting member 21 is an electric hydraulic push rod.

[0034] A plug connector 22 is formed at the bottom of the support 2. The plug connector 22 can be movably inserted into the socket 10. Specifically, in the socket, the plug connector can move up and down along the axial direction of the socket and can rotate in the socket (i.e., rotate around the central axis of the socket).

[0035] The self-locking structure 3 is used to lock the rods of the truss. Specifically, the self-locking structure includes a riser 31, a support plate 32 and a push rod 33.

[0036] There are two vertical pipes 31. The two vertical rods are fixed on the top of the base 2. The two vertical pipes 31 are arranged opposite to each other. The opposite sides of the two vertical pipes 31 are provided with upper and lower through holes.

[0037] An upper through hole and a lower through hole are formed on one side of the vertical pipe. The upper through hole is located above the lower through hole. The lower through hole is strip-shaped and arranged in the vertical direction.

[0038] A rotating disk 35 is rotatably mounted in the riser 31. The rotating disk 35 is vertically arranged. A return torsion spring 36 is installed between the rotating disk 35 and the inner wall of the riser 31.

[0039] The rotating disk 35 is eccentrically provided with an upper rod and a lower rod. The upper rod is arranged above the lower rod. Preferably, the upper rod and the lower rod are respectively arranged on opposite sides of the axis of the rotating disk 35. The lower rod is arranged on opposite sides of the rotating disk 35 in the two risers.

[0040] The ends of the support plate 32 are movably inserted into the lower holes of the two vertical tubes 31. The ends of the support plate 32 extend into the vertical tubes 31 and press against the lower rods. The vertical tubes 31 are equipped with elastic members 37. These members support the support plate 32. A retaining groove is formed in the middle of the support plate 32. This retaining groove is designed to accommodate the lower portion of the truss rod 6. The rods are arranged horizontally.

[0041] A push rod 33 slides in the upper through-hole of each riser. The push rod can slide axially along the upper through-hole. A transmission rod 38 is hingedly connected between one end of the push rod 33 and the upper rod. The transmission rod is tilted. Its lower end is hinged to the upper rod, and its upper end is hinged to one end of the push rod. The other end of the push rod extends outside the riser. Furthermore, a pressure plate 39 is connected to the other end of the push rod 33.

[0042] When assembling the trusses, the rods are arranged horizontally, with their lower portions nestled in the retaining grooves of the support plates. After the support plates bear the pressure of the rods, the ends of the support plates 32 press down on the lower rods, causing the turntables in the two risers to rotate upward and relative to each other. The upper rods of the turntables 35 are pushed outward (toward the exterior of the riser, specifically toward the other riser) against the push rods 33 via the transmission rods 38. The upper pressure plates 39 of the push rods on the two risers approach each other and press against opposite sides of the upper portion of the rod 6, locking the rod 6 between the retaining grooves and the two pressure plates 39.

[0043] As a preferred embodiment, the pressing plate 39 is arc-shaped. The inner arc surfaces of the pressing plate 39 are arranged relative to each other. The outer arc surface of the pressing plate is connected to the other end of the push rod.

[0044] As a preferred embodiment, a magnetic element is fixed to the inner curved surface of the pressure plate for magnetically attracting the rod 6. The rod is a magnetic metal rod. The locking force of the self-locking structure and the magnetic attraction of the magnetic element firmly lock the rod into the limiting groove of the support plate.

[0045] The locking assembly is mounted on the plug connector 22. The locking assembly is used to lock the base 1.

[0046] The driving mechanism is installed in the socket 10. The driving mechanism is used to rotate the plug connector 22 in the socket around the central axis of the socket.

[0047] When assembling the trusses, the pedestal is raised using a lifting member so that the elevation of the retaining grooves in the support plate matches the elevation of the truss rods. Once the pedestal is raised into position, the pedestal's elevation is locked using a locking assembly. Once the pedestal's height is locked, the truss rods are inserted into the retaining grooves of the support plates of the truss assembly frame structure provided by the present invention. Finally, the web members are welded between the rods to form a tubular truss.

[0048] In this embodiment, the electric hydraulic push rod has a fixed end and a telescopic end. The fixed end of the electric hydraulic push rod is detachably mounted to the bottom of the support platform 2. The telescopic end of the electric hydraulic push rod is mounted with a roller. The top of the base 1 is supported by the roller.

[0049] As a preferred embodiment, a gap is provided between the plug connector 22 and the socket 10 .

[0050] The plug connector 22 is coaxially arranged with the socket 10. The locking assembly includes:

[0051] The locking plates 41 are formed on opposite sides of the socket 10. The locking plates 41 are provided with a plurality of locking holes arranged along the axial direction of the socket 10.

[0052] Arc-shaped locking rods 42 are mounted on opposite side walls of the plug connector 22. These rods 42 are arranged along the circumference of the socket 10. These rods 42 are movably inserted into a locking hole in a locking plate 41. When the drive mechanism rotates the plug connector 22, the rods 42 are pushed out of the locking hole, unlocking the base 1.

[0053] A guide tube 311 is fixedly mounted in the vertical tube 31. The guide tube 311 is connected to the upper through hole. One end of the push rod is slidably mounted in the guide tube 311. A sliding hole is formed in the middle of the guide tube 311. The transmission rod 38 is slidably mounted in the sliding hole.

[0054] As a preferred embodiment, the driving mechanism includes a plug board 51 and a motor.

[0055] Continue reading Figure 3 As shown, a slot is defined at the bottom of the plug connector 22. An insert plate 51 is inserted into the slot, movable along the depth of the slot. A positioning hole is defined at the bottom of the receiving hole of the base. A support plate 511 is rotatably mounted in the positioning hole. The insert plate 51 is mounted vertically on the support plate 511. A motor is connected to the support plate 511.

[0056] A motor is fixedly mounted in the positioning hole. Its output shaft is coaxially connected to the support plate. The motor drives the support plate to rotate, which in turn rotates the pedestal, forcing the curved locking rod out of the locking hole and unlocking the base. When the electric hydraulic push rod extends to adjust the pedestal's elevation, the motor drives the support plate to rotate in the opposite direction, inserting the curved locking rod into a locking hole at a suitable height, thereby relocking the pedestal's elevation.

[0057] In this embodiment, the cross section of the positioning hole is cross-shaped, and the shape of the inserting plate matches the shape of the positioning hole.

[0058] The outer wall of the plug connector is provided with an arc-shaped locking rod through a support rod. The length of the arc-shaped locking rod is greater than the depth of the lock hole. In this embodiment, after the plug plate rotates the support platform, the arc-shaped locking rods on both sides of the plug connector are simultaneously withdrawn from the lock hole.

[0059] In addition, an arcuate groove is formed on the outer edge of the top of the base. The arcuate groove is arranged along the circumferential direction of the socket. The lower end of the lifting member is slidably arranged in the arcuate groove.

[0060] The cradle structure for truss assembly of the present invention utilizes the weight of the rods and other components of the tube truss to press down the support plate to turn the turntable, so that the upper rod of the turntable pushes against the push rod, and then the pressure plate on the push rod locks the rod, thereby achieving a firm and stable installation of the rods of the tube truss, thereby improving the splicing accuracy of the tube truss. On the other hand, by lifting the jacking part and locking the locking part, the locking elevation is achieved after adjusting the setting height of the support plate of the base, further improving the installation stability of the tube truss, and being suitable for the splicing of tube trusses of various specifications.

[0061] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept.
