Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a truss moving device. Background Technology

[0002] With the development of construction technology, trusses are widely used in fields requiring large-span building structures. When constructing facilities such as waterways, roads, and bridges, trusses are large in size and mass, making the safe and efficient dismantling of large trusses a crucial aspect of construction.

[0003] The most common demolition method is mechanical hoisting, which involves disassembling the connecting parts of the large truss at the original assembly nodes, then breaking the truss into Bailey panels, moving the hoisting equipment to fix the Bailey panels with its traction hooks, and then removing it from the bridge structure to achieve the hoisting and demolition of the truss.

[0004] Regarding the aforementioned technologies, during bridge truss construction, hoisting equipment can only be placed on one side of the bridge, making it difficult to directly hoist Bailey panels located far from the equipment. The inventors believe there is a need to provide a device that can move Bailey panels from a distance to the hoisting equipment. Utility Model Content

[0005] To enable the movement of the Bailey panels, this application provides a truss moving device.

[0006] The truss moving device provided in this application adopts the following technical solution: A truss moving device includes a moving frame and at least two sets of bottom wheel assemblies mounted on the moving frame and spaced apart along the conveying direction; the bottom wheel assembly includes a positioning pin penetrating both sides of the moving frame and a support bottom wheel rotatably mounted on the positioning pin; the moving frame includes a support panel, two side panels respectively mounted on both sides of the support panel, and a limiting roller mounted on the side panels and used to abut against the bottom surface of the upper side plate of the support beam.

[0007] By adopting the above technical solution, the support panel on the mobile frame can support and fix the Bailey panels, making them less likely to fall off. The bottom wheel assembly provides support at the bottom and allows the mobile frame to move, enabling the device to move forward stably. The limiting rollers on the mobile frame can limit the lateral and vertical vibrations of the mobile frame, keeping the overall mobile frame stable.

[0008] Optionally, the number of supporting bottom wheels in the bottom wheel assembly is two; the two supporting bottom wheels in the same group of bottom wheel assemblies are a first roller and a second roller, and the first roller and the second roller in the same group of bottom wheel assemblies are arranged symmetrically from left to right.

[0009] By adopting the above technical solution, the two supporting bottom wheels in the same bottom wheel assembly can improve the support effect of the bottom wheel assembly. The first roller and the second roller are arranged symmetrically on the left and right sides, so that the mobile frame is subjected to more uniform force during operation, improves the running stability, and enhances the load-bearing capacity of the truss moving device.

[0010] Optionally, the support panel is provided with a first reinforcing side plate on both sides of the first roller, and the first reinforcing side plate has a first through hole for arranging the positioning pin; the support panel is provided with a second reinforcing side plate on both sides of the second roller, and the second reinforcing side plate has a second through hole for arranging the positioning pin.

[0011] By adopting the above technical solution, first reinforcing side plates are provided on both sides of the first roller, and the first reinforcing side plates are provided with first through holes for the positioning pin shaft to be arranged. Second reinforcing side plates are provided on both sides of the second roller, and the second reinforcing side plates are provided with second through holes for the positioning pin shaft to be arranged. This can provide an installation position and support for the positioning pin shaft, and further improve the stability and durability of the connection between the bottom wheel assembly and the mobile frame.

[0012] Optionally, the bottom of the support panel is provided with a first rib plate supporting the opposite sides of the two first reinforcing side plates; the bottom of the support panel is provided with a second rib plate supporting the opposite sides of the two second reinforcing side plates.

[0013] By adopting the above technical solution, a first rib is provided between the two first reinforcing side plates, which supports the first reinforcing side plates and enhances their stability. Similarly, a second rib is provided between the two second reinforcing side plates, which supports the second reinforcing side plates and enhances their stability. Overall, the structural strength of the support panel and the reinforcing side plates is enhanced, improving the stability and load-bearing capacity of the entire truss moving device.

[0014] Optionally, the limiting roller has a supporting portion for abutting the bottom surface of the upper side plate of the supporting beam and a limiting portion for abutting the side edge of the upper side plate of the supporting beam.

[0015] By adopting the above technical solution, a support part and a limiting part of the limiting roller are disclosed. The support part can cooperate with the supporting bottom wheel to clamp the device at the upper side plate of the supporting crossbeam. Through the cooperation of the limiting parts on both sides, the degree of lateral displacement of the device during movement is limited, which is conducive to the stable movement of the device along the length direction of the upper side plate of the supporting crossbeam.

[0016] Optionally, each side panel is provided with two limiting rollers.

[0017] By adopting the above technical solution, the two limiting rollers on the side panel can enhance the front and rear limiting effect of the mobile frame, reduce the probability of the truss moving device slipping off or deviating from the supporting crossbeam, and improve the overall stability of the mobile frame.

[0018] Optionally, the mobile frame is provided with traction crossbars at both the front and rear ends, and the two ends of the traction crossbars are respectively fixed to the corresponding side panels.

[0019] By adopting the above technical solution, traction crossbars are provided at both the front and rear ends of the mobile frame. Traction hooks can be connected to the traction crossbars to realize the forward and backward movement of the mobile device. The traction crossbar at the front of the mobile frame can be connected to the traction hook, and the traction crossbar at the rear of the mobile frame can be connected to the front traction crossbar of another set of mobile frames on the rear side, realizing the linkage of multiple sets of mobile devices.

[0020] Optionally, both ends of the positioning pin are provided with limiting sleeves for abutting against the corresponding side panel, and the limiting sleeves are threadedly engaged with the positioning pin.

[0021] By adopting the above technical solution, the limiting sleeve is installed at both ends of the positioning pin through a threaded structure, which can cooperate with the side panel to restrict the movement of the positioning pin, reduce the probability of axial movement of the positioning pin, and improve the stability of the positioning pin.

[0022] Optionally, the top of the support panel is also provided with a locking component for locking the Bailey panel. The locking component includes a locking rod for pressing the Bailey panel support legs and two connecting rods respectively connected to the two ends of the locking rod. The connecting rods pass through the support panel and have a locking nut for abutting against the support panel threaded at their bottom ends.

[0023] By adopting the above technical solution, a locking component is provided on the support panel to press and fix the Bailey panels onto the support panel, reducing the displacement of the Bailey panels during the movement of the device, making the movement of the device more stable and safe.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. A truss moving device, which, through the cooperation of a moving frame and a bottom wheel assembly, enables the transport of Bailey panels along a supporting crossbeam to a hoisting device; 2. By setting limit rollers on the mobile frame, arranging two supporting bottom wheels in the same group, fixing the reinforcing side plates and ribs on the support panel, setting limit sleeves on the positioning pin shaft, and locking parts on the support panel to lock the Bailey plates, the stability of the mobile frame structure is improved and the stability of the truss moving device during movement is enhanced. 3.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a truss moving device. (Refer to...) Figure 1 A truss moving device includes a moving frame 1 and three sets of bottom wheel assemblies 2 arranged at intervals along the conveying direction on the lower side of the moving frame 1. The bottom wheel assembly 2 includes a positioning pin 21 passing through both sides of the moving frame 1 and a support bottom wheel 22 rotatably mounted on the positioning pin 21. The moving frame 1 includes a support panel 11, two side panels 12 respectively mounted on both sides of the support panel 11, a traction crossbar 13 located at the front and rear ends of the moving frame 1 and fixed to the two side panels 12, a limiting roller 14 mounted on the side panel 12 and used to abut against the bottom surface of the upper side plate of the support crossbar, and a locking member 15 located at the top of the support panel 11 to lock the Bailey plate.

[0032] Reference Figure 2In a set of bottom wheel assemblies 2, the two supporting bottom wheels 22 are a first roller 221 and a second roller 222, respectively. The axles of the first roller 221 and the second roller 222 pass through the same positioning pin 21 and are arranged coaxially and symmetrically on the lower side of the supporting panel 11. After the two ends of the positioning pin 21 pass through the side panel 12, the portion located on the outer side of the side panel 12 is threaded, and limit sleeves 211 are installed on both sides of the thread. The limit sleeves 211 abut against the outer surface of the side panel 12, and the positioning pin 21 is fixed between the side panels 12 by the limit sleeves 211 on both sides, reducing the probability of axial movement of the positioning pin 21.

[0033] Reference Figure 2 Three sets of bottom roller assemblies 2 are arranged parallel to each other along the conveying direction below the support panel 11. The support panel 11 has first reinforcing side plates 111 on both sides of the first roller 221 and second reinforcing side plates 112 on both sides of the second roller 222. The first and second reinforcing side plates 111 and 112 are arranged vertically along the conveying direction. All three first rollers 221 are arranged between two first reinforcing side plates 111, and all three second rollers 222 are arranged between two second reinforcing side plates 112. Positioning pins 21 pass sequentially through and are fixed to the first through hole 1111 in the first reinforcing side plate 111 and the second through hole 1121 in the second reinforcing side plate 112.

[0034] Reference Figure 2 The bottom of the support panel 11 is provided with two first ribs 113 supporting the opposite sides of the two first reinforcing side plates 111. The first ribs 113 are installed between three adjacent first rollers 221 and are arranged at intervals with the three first rollers 221. The bottom of the support panel 11 is also provided with two second ribs 114 supporting the opposite sides of the two second reinforcing side plates 112. The second ribs 114 are installed between three adjacent second rollers 222 and are arranged at intervals with the three second rollers 222.

[0035] Reference Figure 3 Each side panel 12 has two limiting rollers 14 on its inner side, installed at the front and rear ends of the side panel 12 respectively. Each limiting roller 14 has a support portion 141 for abutting against the bottom surface of the upper side plate of the supporting beam and a limiting portion 142 for abutting against the side edge of the upper side plate of the supporting beam. The limiting portion 142 of the limiting roller 14 installed at the front end of the left side panel 12 abuts against the left side edge of the upper side plate of the supporting beam, and the limiting portion 142 of the limiting roller 14 installed at the front end of the right side panel 12 abuts against the right side edge of the upper side plate of the supporting beam, reducing the probability of lateral deviation of the truss moving device. The support portion 141 of the limiting roller 14 cooperates with the lower surface of the supporting bottom wheel 22 of the bottom wheel assembly 2, enabling the truss moving device to move stably along the length of the upper side plate of the supporting beam.

[0036] Reference Figure 1 and Figure 4 The top surface of the support panel 11 is provided with a locking element 15 for locking the Bailey bridge section. The locking element 15 includes a locking rod 151 for pressing the Bailey bridge section foot and two connecting rods 152 respectively connected to the two ends of the locking rod 151. The connecting rods 152 pass through the support panel 11 and have locking nuts 153 threaded at their bottom ends for abutting against the support panel 11. The locking rod 151 is made of C-shaped locking steel. The connecting rods 152 pass through the support panel 11 and have locking nuts 153 threaded at their bottom ends. The locking nuts 153 abut against the lower side of the support panel 11, fixing the Bailey bridge section foot to the upper side of the support panel 11.

[0037] Reference Figures 1 to 4 The implementation principle of a truss moving device according to an embodiment of this application is as follows: the moving frame 1 supports and locks the Bailey panels, the bottom wheel assembly 2 provides bottom support and movement for the device, and the limiting roller 14 restricts the offset vibration of the moving frame 1, maintaining the stability of the device. Before the device moves, the upper side plate of the supporting crossbeam is inserted between the supporting bottom wheel 22 and the limiting roller 14, the traction hook is connected to the traction crossbar 13, and the Bailey panel support feet are locked to the top of the supporting panel 11 by the locking member 15. Applying traction force to the traction hook drives the moving frame 1, the supporting bottom wheel 22 carries the Bailey panels and the frame to roll along the upper side plate of the supporting crossbeam, and the limiting roller 14 abuts against the lower edge and side edge of the upper side plate of the supporting crossbeam, restricting the device from moving along the length direction of the upper side plate of the supporting crossbeam.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
