Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering, and in particular relates to an adjustable tire frame for an SPMT module vehicle. Background Art

[0002] The SPMT, or self-propelled modular transporter, is a large-scale, integrated mechanical, electrical, and hydraulic system. Utilizing a tire frame, it can transport and install bridges as a whole, enabling rapid construction. To achieve this, a specialized SPMT modular vehicle with an adjustable tire frame is required.

[0003] Existing adjustable tire frames for SPMT modular vehicles are typically constructed using temporary, welded steel structures on-site, tailored to the specific needs of the bridge. Adjusting the height and width of these structures is often difficult, and the varying specifications of different bridges necessitates frequent readjustments. This significantly reduces the applicability and flexibility of the tire frames and increases the workload for those involved. Utility Model Content

[0004] In view of this, the utility model provides an adjustable tire frame for SPMT modular vehicles, which can meet the support requirements of beams of different widths and achieve the purpose of supporting beams of different heights through the cooperation of a fixed frame and its auxiliary mechanisms, thereby realizing multi-mode adjustment of the tire frame, greatly improving its scope of use and flexibility, and facilitating operation by relevant staff.

[0005] In order to solve the above technical problems, the utility model provides an adjustable tire frame for SPMT module vehicles, including a fixed frame and slots symmetrically arranged on both sides of the upper end of the fixed frame, support guide rods are provided at both ends of the opposite wall surfaces of the two slots, and a support plate is slidably connected between the two support guide rods located in the same slot. A mounting groove is provided in the middle of the fixed frame, and the dovetail slide groove arranged in the mounting groove is slidably connected at both ends with symmetrically distributed sliding seats, and connecting plates are rotatably connected in the sliding seats. The middle parts of the opposite inner sides of the two support plates are provided with grooves, and the outer ends of the connecting plates are respectively rotatably connected to the adjacent grooves on the same side. The upper ends of the support plates are provided with support mechanisms for supporting beams, that is, meeting the support requirements of beams of different widths and achieving the purpose of supporting beams of different heights, realizing multi-mode adjustment of the tire frame, greatly improving its scope of use and flexibility, and facilitating operation by relevant staff.

[0006] A bidirectional screw rod is rotatably connected in the groove, and the two ends of the bidirectional screw rod are respectively threadedly connected to the corresponding wire holes on the adjacent sliding seat on the same side. Both ends of the fixing frame are provided with through holes corresponding to the ends of the bidirectional screw rod, which plays the role of synchronously driving the sliding seat.

[0007] The supporting mechanism includes multiple mounting plates respectively arranged on the upper ends of the supporting plates. The outsides of the mounting plates are movably sleeved with rectangular sleeves. Ratchet plates are provided on the wall surfaces of the supporting plates close to the bidirectional screw rods. The ratchet plates are respectively cooperated with the ratchet grooves corresponding to the inner wall surfaces of the rectangular sleeves located on the same supporting plate. The screw holes arranged at the outer ends of the rectangular sleeves are threadedly connected with locking bolts, thereby achieving the purpose of supporting beams of different heights.

[0008] The supporting mechanism also includes a plurality of locking holes evenly arranged on the outer side of the mounting plate, and the locking bolts are respectively threadedly connected to the adjacent locking holes on the same side, thereby ensuring the effectiveness of the locking bolts.

[0009] It also includes a support assembly, which is used to provide support for the support plate. The support assembly includes a plurality of load-bearing wire tubes respectively arranged at the lower end of the support plate. The load-bearing wire tubes are all threadedly connected with load-bearing rods.

[0010] Both sides of the fixing frame are provided with avoidance grooves corresponding to the load-bearing wire tubes one by one, that is, they are used to avoid the load-bearing wire tubes after they are reset.

[0011] There are multiple assembly holes at the lower end of the fixing frame, which makes it convenient for relevant staff to fix and install the fixing frame and its auxiliary mechanisms.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. According to the width of the beam, the bidirectional screw is rotated in sequence. Affected by the relationship between the bidirectional screw and the screw hole thread, the sliding seat is driven to move outward along the dovetail groove. While the sliding seat moves, the supporting plate is pushed outward along the supporting guide rod through the connecting plate, thereby adjusting the width of the whole composed of the fixed frame and the support plate to meet the support requirements of beams of different widths.

[0014] 2. When the support height needs to be adjusted, turn the locking bolt counterclockwise to separate the locking bolt from the locking hole, then move the rectangular sleeve to separate the mounting plate and the ratchet groove from the ratchet plate, then move the relative height of the rectangular sleeve. After the rectangular sleeve reaches the appropriate height, move the rectangular sleeve to re-match the ratchet groove with the ratchet plate, then turn the locking bolt to make the locking bolt threadedly connected to the corresponding locking hole, thereby locking the rectangular sleeve, thereby achieving the purpose of supporting beams at different heights, realizing multi-mode adjustment of the tire frame, greatly improving its scope of use and flexibility, and facilitating operation by relevant staff.

[0015] 3. Rotate the load-bearing rod so that it extends out of the load-bearing wire tube until the load-bearing rod contacts the SPMT module car, thereby providing further support for the support plate to prevent the support effect from being weakened after the support plate is extended.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0022] This embodiment provides an adjustable tire frame for SPMT modules. Figure 1-4 As shown: it includes a fixed frame 100 and slots symmetrically arranged on both sides of the upper end of the fixed frame 100. The fixed frame is the basic structure of the entire tire frame and is installed on the SPMT module car. Support guide rods 101 are provided at both ends of the opposite wall surfaces of the two slots. A support plate 102 is slidably connected between the two support guide rods 101 located in the same slot. The support guide rod 101 is used to provide sliding support for the support plate 102 and its ancillary mechanisms. A mounting groove 103 is provided in the middle of the fixed frame 100. The dovetail slide groove arranged in the mounting groove 103 is slidably connected to symmetrically distributed sliding seats 104 at both ends. Connecting plates 105 are rotatably connected in the sliding seats 104. Grooves 106 are provided in the middle of the opposite inner sides of the two support plates 102. The outer ends of the connecting plates 105 are rotatably connected to the adjacent grooves 106 on the same side. The upper ends of the support plates 102 are provided with support mechanisms for supporting beams.

[0023] An appropriate number of fixing frames 100 and their accessories are installed on the SPMT modular vehicle in sequence, and then the sliding seat 104 is driven to move outward along the dovetail groove in sequence according to the width of the beam frame. While moving, the sliding seat 104 pushes the support plate 102 to move outward along the support guide rod 101 through the connecting plate 105, thereby adjusting the width of the whole composed of the fixing frame 100 and the support plate 102 to meet the support requirements of beams of different widths. Then, the supporting mechanism is adjusted to achieve the purpose of supporting beams of different heights, thereby realizing multi-mode adjustment of the tire frame, greatly improving its scope of use and flexibility, and facilitating operation by relevant staff.

[0024] like Figure 1-3 As shown, a bidirectional screw rod 107 is rotatably connected in the groove 106, and a rotating hole is provided in the groove 106 for providing rotational support for the bidirectional screw rod 107. The two ends of the bidirectional screw rod 107 are respectively threadedly connected to the corresponding wire holes on the adjacent sliding seat 104 on the same side. Both ends of the fixing frame 100 are provided with through holes corresponding to the ends of the bidirectional screw rod 107. When the bidirectional screw rod 107 is rotated, it is affected by the threaded relationship between the bidirectional screw rod 107 and the wire hole, thereby driving the sliding seat 104 to move outward along the dovetail groove, thereby playing the role of synchronously driving the sliding seat 104.

[0025] like Figure 1-4 As shown, the support mechanism includes a plurality of mounting plates 200 respectively arranged on the upper end of the support plate 102, and a rectangular sleeve 201 is movably sleeved on the outside of the mounting plate 200, and a ratchet plate 202 is provided on the wall surface of the support plate 102 close to the bidirectional screw rod 107. The ratchet plates 202 are respectively cooperated with the ratchet grooves corresponding to the inner wall surface of the rectangular sleeve 201 located on the same support plate 102, and the screw holes arranged at the outer end of the rectangular sleeve 201 are threadedly connected with locking bolts 203.

[0026] When adjusting the support height, turn the locking bolt 203 counterclockwise, then move the rectangular sleeve 201 to separate the mounting plate 200 and the ratchet groove from the ratchet plate 202, and then move the relative height of the rectangular sleeve 201. After the rectangular sleeve 201 reaches the appropriate height, move the rectangular sleeve 201 to re-match the ratchet groove with the ratchet plate 202, and then turn the locking bolt 203 to lock the rectangular sleeve 201, thereby achieving the purpose of supporting beams at different heights, realizing multi-mode adjustment of the tire frame, greatly improving its scope of use and flexibility, and facilitating operation by relevant staff.

[0027] like Figure 1-4 As shown, the support mechanism also includes a plurality of locking holes 204 evenly arranged on the outer side of the mounting plate 200, and the locking bolts 203 are respectively threadedly connected to the adjacent locking holes 204 on the same side to prevent the locking bolts 203 from loosening and disengaging during tightening, thereby ensuring the use effect of the locking bolts 203.

[0028] like Figure 1-2 As shown, it also includes a support assembly, which is used to provide support for the support plate 102. The support assembly includes a plurality of load-bearing wire tubes 300 respectively arranged at the lower end of the support plate 102. The load-bearing wire tubes 300 are all threadedly connected to the load-bearing rods 301, and the upper ends of the support plates 102 are provided with openings corresponding to the load-bearing rods 301.

[0029] The supporting rod 301 is rotated so as to extend out of the supporting wire tube 300 until the supporting rod 301 contacts the SPMT module vehicle, thereby further supporting the support plate 102 and preventing the support effect of the support plate 102 from being weakened after being extended.

[0030] like Figure 1-2 As shown, both sides of the fixing frame 100 are provided with avoidance grooves 400 corresponding to the load-bearing wire tubes 300 one by one, for avoiding the load-bearing wire tubes 300 after being reset.

[0031] like Figure 1-2 As shown, a plurality of assembly holes are provided at the lower end of the fixing frame 100 to facilitate relevant staff to fix and install the fixing frame 100 and its auxiliary mechanisms.

[0032] The working principle of an adjustable tire frame for an SPMT modular vehicle provided by the present invention is as follows: first, an appropriate number of fixing frames 100 and their accessories are installed on the SPMT modular vehicle through multiple assembly holes at their lower ends, and then the bidirectional screw rods 107 are rotated in sequence according to the width of the beam frame. Under the influence of the threaded relationship between the bidirectional screw rods 107 and the screw holes, the sliding seat 104 is driven to move outward along the dovetail groove, and while the sliding seat 104 moves, it pushes the support plate 102 to move outward along the support guide rod 101 through the connecting plate 105, thereby adjusting the width of the whole composed of the fixing frame 100 and the support plate 102 to meet the support requirements of beams of different widths. After the adjustment is completed, the load-bearing rod 301 is rotated so that the load-bearing rod 301 extends out of the load-bearing wire tube 300 until the load-bearing rod 301 is aligned with the SPMT modular vehicle. The locking bolt 203 is screwed into the corresponding locking hole 204 to lock the rectangular sleeve 201, thereby achieving the purpose of supporting beams of different heights and realizing multi-mode adjustment of the tire frame, which greatly improves its scope of use and flexibility, and is convenient for relevant staff to operate.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
