Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge erection, in particular to an erection device and a bridge erection method. BACKGROUND

[0002] The bridge comprises a rut assembly composed of a long rut and a short rut, and the short rut can rotate relative to the long rut. When erecting the bridge, the short rut often needs to be rotated upward so that the upper surfaces of the short rut and the long rut are flush. The erection device in the related art usually comprises a rotatable rod with a hook at the end and an oil cylinder for driving the rod, and the rod is driven to rotate and lift by the oil cylinder to lift and rotate the short rut. However, the erection device has a complex structure, includes many components, has a large overall weight, occupies a large space, and has a high product cost. SUMMARY

[0003] The present application aims to at least solve one of the problems in the prior art or related art.

[0004] To this end, a first aspect of the present application provides an erection device.

[0005] A second aspect of the present application provides a bridge erection method.

[0006] To achieve the above at least one purpose, the present application provides an erection device for erecting a bridge, the bridge comprising at least one unit module bridge span, the unit module bridge span comprising a rut assembly, the rut assembly comprising a first rut and a second rut, the first rut being hinged to the second rut, the rut assembly being switchable between a first state and a second state, when the rut assembly is in the first state, the upper surface of the first rut is flush with the upper surface of the second rut, when the rut assembly is in the second state, the lower surface of the first rut is flush with the lower surface of the second rut, the erection device comprising: a main body; a support assembly installed on the main body, the support assembly being used for supporting the first rut and adjusting the height of the connecting end of the first rut and the second rut; a pad removably placed on the main body, the pad being used for supporting the second rut; wherein when it is needed to adjust the rut assembly to the first state, the pad is placed on the main body and supports the second rut, the support assembly lowers the height of the connecting end of the first rut and the second rut to rotate the first rut and the second rut towards each other until the upper surface of the first rut is flush with the upper surface of the second rut; when it is needed to adjust the rut assembly to the second state, the pad is removed from the main body so that the second rut rotates under the action of gravity away from the upper surface of the first rut until the lower surface of the first rut is flush with the lower surface of the second rut.

[0007] The erection device is used for erecting a bridge, the bridge comprising one unit module bridge span or two unit module bridge spans, each unit module bridge span comprising a rut assembly, the number of the rut assemblies in each unit module bridge span being two, and the two rut assemblies being arranged in a central symmetric form. Each rut assembly comprises a first rut and a second rut, wherein the length of the first rut is greater than that of the second rut, the upper surface and the lower surface of the first rut are two parallel or nearly parallel planes, and the upper surface and the lower surface of the second rut form an included angle, which is an acute angle. The two first ruts of the two rut assemblies in each unit module bridge span are arranged in a diagonal manner, and the two second ruts of the two rut assemblies in each unit module bridge span are also arranged in a diagonal manner, i.e., the two first ruts in each unit module bridge span are not adjacent, and the two second ruts are also not adjacent. When the bridge comprises two unit module bridge spans, the first rut in one unit module bridge span is overlapped with the second rut in the other unit module bridge span. The first rut and the second rut are hinged, and specifically, the hinge point of the first rut and the second rut is located at the bottom of the first rut and the second rut. The second rut can rotate relative to the first rut about the hinge point to switch the rut assembly between a first state and a second state. When the rut assembly is in the first state, the upper surface of the first rut is flush with the upper surface of the second rut, and when the rut assembly is in the second state, the lower surface of the first rut is flush with the lower surface of the second rut. The erection device can adjust the relative position between the first rut and the second rut to switch the rut assembly between the first state and the second state.

[0008] Further, the erection device comprises a main body, a support assembly and a pad, wherein the support assembly is used for adjusting the height of the connecting end of the first rut and the second rut, and the pad is used for supporting the second rut. The support assembly is installed on the main body, the support assembly can support the first rut and adjust the height of the connecting end of the first rut and the second rut, and the pad is placed on the main body in a removable manner, and the second rut can be supported by the pad or the second pad can be removed from the main body according to needs.

[0009] Further, in the case that the erected bridge comprises two unit module bridge spans, one of the track assemblies in any unit module bridge span is in the first state and the other track assembly is in the second state. When the two unit module bridge spans are connected, the second track in the track assembly in the first state cooperates with the first track in the track assembly in the second state, the lower surface of the second track cooperates with the upper surface of the first track to form the bridge. In the case that the erected bridge comprises only one unit module bridge span, the track assembly comprised by the unit module bridge span is the track assembly in the second state. Whether the pad is used is determined according to the state of the track assembly required. Specifically, when the track assembly needs to be adjusted to the first state, the pad is placed on the main body and supports the second track, the second track is supported by the pad, and then the height of the connecting end of the first track and the second track is lowered by the support assembly. Since the pad supports the second track, when the height of the connecting end of the first track and the second track is lowered, the pad exerts a force on the second track, the first track and the second track rotate towards each other until the upper surface of the first track is flush with the upper surface of the second track, and the track assembly in the first state is obtained. When the track assembly needs to be adjusted to the second state, the pad is removed from the main body, the second track is no longer supported by the pad, and the second track rotates in a direction away from the upper surface of the first track under the action of gravity until the lower surface of the first track is flush with the lower surface of the second track, and the track assembly in the second state is obtained.

[0010] By providing the pad that can be removed from the main body in the erecting device, the relative position between the first track and the second track can be adjusted by the pad according to the need of supporting or not supporting the second track by the pad, without providing too many structures on the main body for adjusting the height of the second track, thereby simplifying the structure of the erecting device, reducing the installation space of the erecting device, and reducing the cost of the erecting device.

[0011] According to the erecting device described above, the erecting device can further have the following distinguished technical features:

[0012] In some technical solutions, optionally, the first track has a first support area and a second support area, the second support area is located between the connecting end of the first track and the second track and the first support area, the support assembly can contact the first support area and the second support area, and the support assembly controls the second support area to rotate around the first support area in a direction towards the main body to lower the height of the connecting end of the first track and the second track.

[0013] In the technical solution, the operation mode of the support assembly is limited. The support assembly supports the first rut and can adjust the height of the connecting end of the first rut and the second rut. The first rut has a first support area and a second support area, and the support assembly contacts the first rut in the first support area and the second support area and supports the first rut. Among them, the second support area is located between the connecting end of the first rut and the second rut and the first support area, and when it is necessary to lower the height of the connecting end of the first rut and the second rut, the part of the support assembly contacting the second support area is lowered in height, and the part of the support assembly contacting the first support area remains unchanged in height. In this way, the second support area can rotate around the first support area in the direction towards the main body, thereby lowering the height of the connecting end of the first rut and the second rut.

[0014] By setting the support assembly to be capable of contacting two areas of the first rut, the height of the connecting end of the first rut and the second rut can be adjusted by adjusting the height of the part of the support assembly contacting the two areas.

[0015] In some technical solutions, the support assembly comprises a first support member mounted on the main body, the first support member being configured to contact the first support area, and a second support member mounted on the main body, the second support member being configured to contact the second support area. When it is necessary to adjust the rut assembly to the first state, the first support member remains unchanged in height, and the second support member retracts in the direction towards the main body, so that the second support area rotates around the first support area in the direction towards the main body, thereby lowering the height of the connecting end of the first rut and the second rut.

[0016] In the technical solution, the structure of the support assembly is limited. The support assembly comprises a first support member and a second support member, both of which are mounted on the main body. The first support member is configured to contact the first support area, and the second support member is configured to contact the second support area. The second support member can be retracted relative to the main body to adjust the height of the connecting end of the first rut and the second rut. Specifically, when it is necessary to adjust the rut assembly to the first state, the first support member remains unchanged in height, and the second support member retracts in the direction towards the main body, so that the first support member becomes the fulcrum, the second support area rotates around the first support area in the direction towards the main body, thereby lowering the height of the connecting end of the first rut and the second rut.

[0017] By providing the first support member and the second support member in the support assembly, and supporting the first support area of the first rut by the first support member and supporting the second area of the first rut by the second support member, the height of the connecting end of the first rut and the second rut can be adjusted by adjusting the height of the second support member.

[0018] In some embodiments, the spacer is capable of being supported on a support region of the second track, the support region being located between the hinge point of the first track and the second track and the end point of the second track away from the first track.

[0019] In this embodiment, the position of the spacer is limited. Specifically, the spacer is capable of being supported on a support region of the second track, the support region being located between the hinge point of the first track and the second track and the end point of the second track away from the first track. Understandably, when the height of the hinge point of the first track and the second track is lowered, the first track drives the second track to rotate relative to the spacer. If the support position of the spacer on the second track is located at the end of the second track, it is easy to cause the second track to be unstable due to the excessive rotation range. If the support position of the spacer on the second track is located at the hinge point of the first track and the second track, it will cause the second track to be unable to rotate. By setting the support position of the spacer on the second track between the hinge point of the first track and the second track and the end point of the second track away from the first track, the second track can be kept stable while ensuring the normal rotation of the second track.

[0020] The second aspect of the present application also provides a method for erecting a bridge, which is performed by the erecting device as provided in the first aspect of the present application. The method for erecting a bridge comprises: confirming whether the bridge comprises two unit module bridge spans; if the bridge comprises two unit module bridge spans, adjusting the state of one track assembly in any one of the two unit module bridge spans, placing a spacer on the main body of the erecting device, and supporting the second track of the track assembly by the spacer; lowering the height of the connection end of the first track and the second track of the track assembly by the support assembly until the upper surfaces of the first track and the second track are flush, so as to adjust one track assembly in any one of the two unit module bridge spans to a first state; adjusting the state of another track assembly in any one of the two unit module bridge spans, removing the spacer from the main body, so that the second track rotates in the direction away from the upper surface of the first track under the action of gravity until the lower surface of the first track is flush with the lower surface of the second track, so as to adjust another track assembly in any one of the two unit module bridge spans to a second state; matching the second track of the track assembly in the first state in one unit module bridge span with the first track in another unit module bridge span to obtain the bridge.

[0021] The bridge erecting method provided in the present application is used in an erecting device for erecting a bridge. First, it is determined whether the bridge comprises a single unit module bridge span or two unit module bridge spans. If the bridge comprises two unit module bridge spans, one of the track assemblies in any one of the unit module bridge spans is adjusted to a first state, and the other track assembly is adjusted to a second state. Then, the second track of the track assembly in the first state is matched with the first track of the track assembly in the second state, and the lower surface of the second track is matched with the upper surface of the first track, so as to form the bridge.

[0022] Specifically, if the bridge comprises two unit module bridge spans, the state of one of the track assemblies in any one of the unit module bridge spans is adjusted to a first state. First, a pad is placed on the main body of the erecting device to support the second track of the track assembly. Then, the height of the connecting end of the first track and the second track of the track assembly is lowered by a supporting assembly until the upper surfaces of the first track and the second track are flush, so as to adjust one of the track assemblies in any one of the unit module bridge spans to the first state.

[0023] Further, after adjusting one of the track assemblies in any one of the unit module bridge spans to the first state, the other track assembly of any one of the unit module bridge spans is adjusted to a second state. First, the pad is removed from the main body, and the second track is no longer supported by the pad. In this way, the second track can rotate in a direction away from the upper surface of the first track under the action of gravity until the lower surface of the first track is flush with the lower surface of the second track, so as to adjust the other track assembly of any one of the unit module bridge spans to the second state.

[0024] Further, after adjusting the two track assemblies in any one of the unit module bridge spans to the first state and the second state respectively, the second track of the track assembly in one of the unit module bridge spans in the first state is matched with the first track of the other unit module bridge span to obtain the bridge. Specifically, since the upper surface and the lower surface of the second track have an included angle, which is an acute angle, the lower surface of the second track of the track assembly in the first state is a slope, and the upper surface of the first track is also a slope. The two slopes are matched with each other. When the two unit module bridge spans are combined, the lower surface of the second track of the track assembly in the first state in one of the unit module bridge spans is attached to the upper surface of the first track of the other unit module bridge span, and the lower surface of the second track of the track assembly in the second state is flush with the lower surface of the first track, which can be attached to the ground or other platforms, so as to obtain the bridge.

[0025] By adopting the bridge erecting method, the second track can be supported or not supported by the cushion block according to requirements, so that the relative position between the first track and the second track can be adjusted by the cushion block, and the structure of the erecting device is simplified, and the installation space of the erecting device is reduced.

[0026] In some technical solutions, the support assembly comprises a first support member and a second support member, the first support member is configured to contact the first support region of the first track, and the second support member is configured to contact the second support region of the first track, the second support region is located between the connecting end of the first track and the second track and the first support region, and the height of the connecting end of the first track and the second track of the track assembly is lowered by the support assembly, specifically: the height of the first support member is kept unchanged, and the second support member is controlled to shrink in the direction towards the main body, so that the second support region rotates around the first support region in the direction towards the main body, thereby lowering the height of the connecting end of the first track and the second track.

[0027] In this technical solution, the bridge erecting method is further limited. The first track has a first support region and a second support region, and the support assembly contacts the first track at the first support region and the second support region, respectively. The support assembly comprises a first support member and a second support member, the first support member is configured to contact the first support region, and the second support member is configured to contact the second support region. The second support region is located between the connecting end of the first track and the second track and the first support region. When the height of the connecting end of the first track and the second track of the track assembly is lowered by the support assembly, the specific working mode of the erecting device is as follows: first, the height of the first support member is kept unchanged, so that the height of the first support region remains unchanged, and then the second support member is controlled to shrink in the direction towards the main body, so that the first support member becomes a fulcrum, the second support region rotates around the first support region in the direction towards the main body, and the height of the connecting end of the first track and the second track is lowered.

[0028] By providing the first support member and the second support member in the support assembly, and supporting the first support region of the first track by the first support member and supporting the second region of the first track by the second support member, the height of the connecting end of the first track and the second track can be adjusted by adjusting the height of the second support member.

[0029] In some technical solutions, the cushion block is placed on the main body of the erecting device, specifically: the cushion block is placed between the hinge point of the first track and the second track and the end point of the second track away from the first track.

[0030] In the technical solution, the method for erecting the bridge is further limited. The cushion block is used to support the second rut, and the supporting position of the cushion block on the second rut is between the hinged point of the first rut and the second rut and the end point of the second rut away from the first rut. Understandably, when the height of the hinged point of the first rut and the second rut is lowered, the first rut drives the second rut to rotate relative to the cushion block, if the supporting position of the cushion block on the second rut is at the end of the second rut, it is easy to cause the second rut to be unstable due to too large rotation range, and if the supporting position of the cushion block on the second rut is at the hinged point of the second rut and the first rut, it will cause the second rut to be unable to rotate. The application can ensure the normal rotation of the second rut while keeping the second rut stable by setting the supporting position of the cushion block on the second rut between the hinged point of the first rut and the second rut and the end point of the second rut away from the first rut.

[0031] In some technical solutions, optionally, after the upper surfaces of the first rut and the second rut are flush, the method further comprises: inserting a fixing member between the first rut and the second rut to keep the first rut and the second rut relatively fixed, to obtain the rut assembly in the first state.

[0032] In the technical solution, the method for erecting the bridge is further limited. After the upper surfaces of the first rut and the second rut are adjusted to be flush, the first rut and the second rut are fixed. Specifically, a fixing member is inserted between the first rut and the second rut, and the first rut and the second rut are fixedly connected by the fixing member, so that the first rut and the second rut are kept relatively fixed, to obtain the rut assembly in the first state.

[0033] In a possible technical solution, the first rut and the second rut are both provided with a connecting hole, and the fixing member is a bolt, which is inserted into the connecting holes of the first rut and the second rut that overlap each other, to realize the fixed connection of the first rut and the second rut.

[0034] By inserting the fixing member between the first rut and the second rut, the first rut and the second rut can be fixedly connected by the fixing member to avoid relative rotation between the first rut and the second rut.

[0035] In some technical solutions, optionally, the method for erecting the bridge further comprises: if the bridge comprises a single unit module bridge span, removing the cushion block from the main body to make the second rut rotate under the action of gravity in a direction away from the upper surface of the first rut, until the lower surface of the first rut is flush with the lower surface of the second rut, to adjust the rut assembly in the single unit module bridge span to the second state.

[0036] In the technical solution, the method for erecting the bridge is further limited. It is confirmed that the bridge comprises a single unit module bridge span or two unit module bridge spans, if the bridge comprises a single unit module bridge span, the lower surfaces of the first rut and the second rut of the rut assembly in the single unit module bridge span are adjusted to be flush, that is, the rut assembly in the single unit module bridge span is adjusted to the second state. The shims are removed from the main body first, and the second rut is no longer supported by the shims, so that the second rut can rotate in the direction away from the upper surface of the first rut under the action of gravity. Until the lower surface of the first rut is flush with the lower surface of the second rut, the rut assembly in the single unit module bridge span is adjusted to the second state.

[0037] In some technical solutions, optionally, a fixing member is inserted between the first rut and the second rut to keep the first rut and the second rut relatively fixed, to obtain the bridge.

[0038] In the technical solution, the method for erecting the bridge is further limited. After the rut assembly in the single unit module bridge span is adjusted to the second state, the first rut and the second rut are fixed. Specifically, a fixing member is inserted between the first rut and the second rut, and the first rut and the second rut are fixedly connected by the fixing member, so that the first rut and the second rut are kept relatively fixed, to obtain the rut assembly in the second state, and the single unit module bridge span comprising the rut assembly in the second state constitutes the bridge.

[0039] By inserting the fixing member between the first rut and the second rut, the first rut and the second rut can be fixedly connected by the fixing member to avoid relative rotation between the first rut and the second rut.

[0055] The following will refer to Figures 1 to 11 The erecting device 100 and the method of erecting the bridge according to some embodiments of the present application are described.

[0056] In an embodiment according to the present application, as Figure 1 , Figure 2 ,Figure 4 、 Figure 9 、 Figure 10 and Figure 11 As shown in FIG. 1, the present application provides an erecting device 100 for erecting a bridge, the bridge comprising at least one unit module bridge span 210, the unit module bridge span 210 comprising a track assembly 220, the track assembly 220 comprising a first track 221 and a second track 222, the first track 221 being hingedly connected to the second track 222, the track assembly 220 being switchable between a first state and a second state, when the track assembly 220 is in the first state, an upper surface 223 of the first track is flush with an upper surface 225 of the second track, when the track assembly 220 is in the second state, a lower surface 224 of the first track is flush with a lower surface 226 of the second track, the erecting device 100 comprising: a main body 110; a support assembly 120 mounted on the main body 110, the support assembly 120 being configured to support the first track 221 and to adjust a height of a connecting end of the first track 221 and the second track 222; a spacer 130 removably placed on the main body 110, the spacer 130 being configured to support the second track 222; wherein, when it is required to adjust the track assembly 220 to the first state, the spacer 130 is placed on the main body 110 and supports the second track 222, the support assembly 120 lowers the height of the connecting end of the first track 221 and the second track 222, so that the first track 221 and the second track 222 rotate towards each other until the upper surface 223 of the first track is flush with the upper surface 225 of the second track; when it is required to adjust the track assembly 220 to the second state, the spacer 130 is removed from the main body 110, so that the second track 222 rotates under the action of gravity in a direction away from the upper surface 223 of the first track until the lower surface 224 of the first track is flush with the lower surface 226 of the second track.

[0057] The erecting device 100 provided by the present application is used for erecting a bridge. As shown in FIG. 1, the bridge comprises one unit module bridge span 210 or two unit module bridge spans 210, any one of the unit module bridge spans 210 comprises a track assembly 220, the number of the track assemblies 220 in any one of the unit module bridge spans 210 is two, as shown in FIG. 2, the two track assemblies 220 are arranged in a central symmetric form. Any one of the track assemblies 220 comprises a first track 221 and a second track 222, wherein the length of the first track 221 is greater than that of the second track 222, the upper surface 223 and the lower surface of the first track are two parallel or nearly parallel planes, the upper surface 225 of the second track and the lower surface thereof form an included angle, and the included angle is an acute angle. Figure 3 Figure 2 Figure 10 ​​As shown, the two first ruts 221 of the two rut assemblies 220 in any unit module bridge span 210 are diagonally arranged, and the two second ruts 222 of the two rut assemblies 220 in any unit module bridge span 210 are diagonally arranged, that is, the two first ruts 221 in any unit module bridge span 210 are not adjacent, and the two second ruts 222 are not adjacent. When the bridge includes two unit module bridge spans 210, the first rut 221 in one unit module bridge span 210 is overlapped with the second rut 222 in the other unit module bridge span 210. The first rut 221 is hinged with the second rut 222, and specifically, the hinge point of the first rut 221 and the second rut 222 is located at the bottom of the first rut 221 and the second rut 222. As shown in FIG. 1, Figure 4 As shown, the second rut 222 can rotate relative to the first rut 221 around the hinge point to switch the rut assembly 220 between the first state and the second state, Figure 4 The arrow in FIG. 2 shows the rotation direction of the second rut. When the rut assembly 220 is in the first state, the upper surface 223 of the first rut is flush with the upper surface 225 of the second rut, and when the rut assembly 220 is in the second state, the lower surface 224 of the first rut is flush with the lower surface 226 of the second rut. The erection device 100 can adjust the relative position between the first rut 221 and the second rut 222 to switch the rut assembly 220 between the first state and the second state.

[0058] Further, as shown in FIG. 3, Figure 1 As shown, the erection device 100 includes a main body 110, a support assembly 120, and a pad 130, wherein the support assembly 120 is used to adjust the height of the connection end of the first rut 221 and the second rut 222, and the pad 130 is used to support the second rut 222. The support assembly 120 is installed on the main body 110, and the support assembly 120 can support the first rut 221 and adjust the height of the connection end of the first rut 221 and the second rut 222. The pad 130 is placed on the main body 110 in a removable manner, and the second pad 130 can be selected to support the second rut 222 or removed from the main body 110 according to the need.

[0059] Further, in the case that the erected bridge comprises two unit module bridge spans 210, one of the track assemblies 220 in any unit module bridge span 210 is in the first state and the other track assembly 220 is in the second state. When the two unit module bridge spans 210 are connected, the second track 222 in the track assembly 220 in the first state cooperates with the first track 221 in the track assembly 220 in the second state, and the lower surface 226 of the second track 222 cooperates with the upper surface 223 of the first track 221 to form the bridge. In the case that the erected bridge comprises only one unit module bridge span 210, the track assembly 220 comprised by the unit module bridge span 210 is the track assembly 220 in the second state. Whether the spacer 130 is used is determined according to the state of the track assembly 220 required. Specifically, when the track assembly 220 needs to be adjusted to the first state, the spacer 130 is placed on the main body 110 and supports the second track 222, the second track 222 is supported by the spacer 130, and then the height of the connecting end of the first track 221 and the second track 222 is lowered by the support assembly 120. Since the spacer 130 supports the second track 222, when the height of the connecting end of the first track 221 and the second track 222 is lowered, the spacer 130 exerts a force on the second track 222, and the first track 221 and the second track 222 rotate towards each other until the upper surface 223 of the first track and the upper surface 225 of the second track are flush, obtaining the track assembly 220 in the first state. When the track assembly 220 needs to be adjusted to the second state, the spacer 130 is removed from the main body 110, and the second track 222 is no longer supported by the spacer 130, and the second track 222 rotates under the action of gravity away from the upper surface 223 of the first track until the lower surface 224 of the first track and the lower surface 226 of the second track are flush, obtaining the track assembly 220 in the second state.

[0060] By providing the spacer 130 that can be removed from the main body 110 in the erecting device 100, the spacer 130 is used to support or not support the second track 222 as required, so that the relative position between the first track 221 and the second track 222 can be adjusted by the spacer 130, and there is no need to provide too many structures on the main body 110 for adjusting the height of the second track 222, which simplifies the structure of the erecting device 100, reduces the installation space of the erecting device 100, and reduces the cost of the erecting device 100.

[0061] In some embodiments, the first rut 221 may have a first support region and a second support region. The second support region is located between the connection end of the first rut 221 and the second rut 222 and the first support region. The support component 120 is capable of contacting the first support region and the second support region. The support component 120 controls the second support region to rotate around the first support region in a direction toward the body 110 to lower the height of the connection end of the first rut 221 and the second rut 222.

[0062] In this embodiment, the operation mode of the support component 120 is defined. The support component 120 supports the first rut 221 and can adjust the height of the connection end between the first rut 221 and the second rut 222. The first rut 221 has a first support region and a second support region. The support component 120 contacts the first rut 221 in the first support region and the second support region respectively, and supports the first rut 221. The second support region is located between the connection end between the first rut 221 and the second rut 222 and the first support region. When it is necessary to lower the height of the connection end between the first rut 221 and the second rut 222, the height of the part of the support component 120 that contacts the second support region decreases, while the height of the part of the support component 120 that contacts the first support region remains unchanged. In this way, the second support region can rotate around the first support region in the direction toward the main body 110, thereby lowering the height of the connection end between the first rut 221 and the second rut 222.

[0063] By configuring the support component 120 to contact two areas of the first rut 221, the height of the connection end of the first rut 221 and the second rut 222 can be adjusted by adjusting the height of the part of the support component 120 that contacts these two areas.

[0064] In some embodiments, optionally, such as Figure 1 As shown, the support assembly 120 includes: a first support member 121, mounted on the main body 110, which is used to contact the first support area; and a second support member 122, mounted on the main body 110, which is used to contact the second support area. When the rut assembly 220 needs to be adjusted to the first state, the first support member 121 maintains a constant height, and the second support member 122 retracts in the direction toward the main body 110, so that the second support area rotates around the first support area in the direction toward the main body 110, thereby reducing the height of the connection end between the first rut 221 and the second rut 222.

[0065] In this embodiment, the structure of the support assembly 120 is defined. The support assembly 120 comprises a first support 121 and a second support 122, both of which are mounted to the main body 110, wherein the first support 121 is configured to contact the first support region and the second support 122 is configured to contact the second support region. The second support 122 is telescopic relative to the main body 110 to adjust the height of the connecting end of the first track 221 and the second track. Specifically, when it is required to adjust the track assembly 220 to the first state, the first support 121 remains unchanged in height, and the second support 122 is retracted in the direction towards the main body 110, so that the first support 121 becomes the fulcrum, and the second support region rotates around the first support region in the direction towards the main body 110, thereby lowering the height of the connecting end of the first track 221 and the second track 222.

[0066] By providing the first support 121 and the second support 122 in the support assembly 120, and supporting the first support region of the first track 221 by the first support 121 and supporting the second region of the first track 221 by the second support 122, the height of the connecting end of the first track 221 and the second track 222 can be adjusted by adjusting the height of the second support 122.

[0067] In some embodiments, optionally, the pad 130 can be supported on the support region of the second track 222, which is between the hinge point of the first track 221 and the second track 222 and the end point of the second track 222 away from the first track 221.

[0068] In this embodiment, the position of the pad 130 is defined. Specifically, the pad 130 can be supported on the support region of the second track 222, which is between the hinge point of the first track 221 and the second track 222 and the end point of the second track 222 away from the first track 221. Understandably, when the height of the hinge point of the first track 221 and the second track 222 is lowered, the first track 221 drives the second track 222 to rotate relative to the pad 130, if the support position of the pad 130 on the second track 222 is at the end of the second track 222, it is easy to cause the second track 222 to be unstable due to the excessive rotation range, and if the support position of the pad 130 on the second track 222 is at the hinge point of the second track 222 and the first track 221, it will cause the second track 222 to be unable to rotate. By setting the support position of the pad 130 on the second track 222 between the hinge point of the first track 221 and the second track 222 and the end point of the second track 222 away from the first track 221, the present application can ensure the normal rotation of the second track 222 while keeping the second track 222 stable.

[0069] A second aspect of the present application provides a bridge erecting method, which is performed by the erecting device of any of the above embodiments, and the bridge erecting method comprises the following steps S102-S110: Figure 5 As shown in FIG. 1, one of the flowcharts of the bridge erecting method of the embodiments of the present application is shown. The bridge erecting method comprises the following steps S102-S110:

[0070] S102: Determine whether the bridge comprises two unit module bridge spans, if yes, execute step S104, if no, execute step S112;

[0071] S104: Adjust the state of one of the track assemblies in any one of the two unit module bridge spans, place the pad on the main body of the erecting device, and support the second track of the track assembly by the pad;

[0072] S106: Lower the height of the connecting end of the first track and the second track of the track assembly by the support assembly until the upper surfaces of the first track and the second track are flush, so as to adjust one of the track assemblies in any one of the two unit module bridge spans to the first state;

[0073] S108: Adjust the state of the other track assembly in any one of the two unit module bridge spans, remove the pad from the main body, so that the second track rotates under the action of gravity away from the upper surface of the first track until the lower surface of the first track is flush with the lower surface of the second track, so as to adjust the other track assembly in any one of the two unit module bridge spans to the second state;

[0074] S110: Match the second track of the track assembly in the first state in one unit module bridge span with the first track in the other unit module bridge span to obtain the bridge;

[0075] S112: Remove the pad from the main body, so that the second track rotates under the action of gravity away from the upper surface of the first track until the lower surface of the first track is flush with the lower surface of the second track, so as to adjust the track assembly in the unit module bridge span to the second state;

[0076] S114: Insert the fixing member between the first track and the second track to keep the first track and the second track relatively fixed to obtain the bridge.

[0077] The bridge erecting method provided in the present application is used in an erecting device for erecting a bridge. First, it is determined whether the bridge comprises a single unit module bridge span or two unit module bridge spans. If the bridge comprises two unit module bridge spans, one rut assembly in any of the unit module bridge spans is adjusted to a first state, and the other rut assembly is adjusted to a second state. Then, the second rut in the rut assembly in the first state is matched with the first rut in the rut assembly in the second state, and the lower surface of the second rut is matched with the upper surface of the first rut, so as to form the bridge. Specifically, if the bridge comprises two unit module bridge spans, the state of one rut assembly in any of the unit module bridge spans is adjusted to a rut assembly in the first state. First, a pad is placed on the main body of the erecting device, and the second rut of the rut assembly is supported by the pad. Then, the height of the connecting end of the first rut and the second rut of the rut assembly is lowered by a supporting assembly until the upper surfaces of the first rut and the second rut are flush, so as to adjust one rut assembly in any of the unit module bridge spans to the first state.

[0078] Further, after one rut assembly in any of the unit module bridge spans is adjusted to the first state, the other rut assembly of any of the unit module bridge spans is adjusted to a rut assembly in the second state. First, the pad is removed from the main body, and the second rut is no longer supported by the pad. In this way, the second rut can rotate in the direction away from the upper surface of the first rut under the action of gravity until the lower surface of the first rut is flush with the lower surface of the second rut, so as to adjust the other rut assembly of any of the unit module bridge spans to the second state.

[0079] Further, after the two rut assemblies in any of the unit module bridge spans are adjusted to the first state and the second state respectively, the second rut of the rut assembly in the first state in one unit module bridge span is matched with the first rut in the other unit module bridge span, so as to obtain the bridge. Specifically, since the upper surface and the lower surface of the second rut have an included angle, which is an acute angle, the lower surface of the second rut in the rut assembly in the first state is a slope, and the upper surface of the first rut is also a slope, and the two slopes are matched with each other. When the two unit module bridge spans are combined, the lower surface of the second rut in the rut assembly in the first state in one unit module bridge span is attached to the upper surface of the first rut in the other unit module bridge span, and the lower surface of the second rut in the rut assembly in the second state is flush with the lower surface of the first rut, which can be attached to the ground or other table surface, so as to obtain the bridge.

[0080] By erecting the bridge by using the erecting method of the bridge, the relative position between the first track and the second track can be adjusted by the cushion block as needed with or without supporting the second track by the cushion block, without needing to set too many structures on the main body for adjusting the height of the second track, thereby simplifying the structure of the erecting device and reducing the installation space of the erecting device.

[0081] Further, if the bridge comprises a single unit module bridge span, the lower surfaces of the first track and the second track in the track assembly in the unit module bridge span are adjusted to be flush, that is, the track assembly in the unit module bridge span is adjusted to the second state. The cushion block is first removed from the main body, and the second track is no longer supported by the cushion block, so that the second track can rotate in the direction away from the upper surface of the first track under the action of gravity. Until the lower surface of the first track is flush with the lower surface of the second track, the track assembly in the unit module bridge span is adjusted to the second state.

[0082] After the track assembly in the single unit module bridge span is adjusted to the second state, the first track and the second track are fixed. Specifically, a fixing member is inserted between the first track and the second track, and the first track and the second track are fixedly connected by the fixing member, so that the first track and the second track remain relatively fixed, obtaining the track assembly in the second state, and the unit module bridge span comprising the track assembly in the second state constitutes the bridge.

[0083] By inserting the fixing member between the first track and the second track, the first track and the second track can be fixedly connected by the fixing member to avoid relative rotation between the first track and the second track.

[0084] In an embodiment according to the present application, the support assembly comprises a first support member and a second support member, the first support member is used to contact the first support area of the first track, and the second support member is used to contact the second support area of the first track, the second support area is located between the connecting end of the first track and the second track and the first support area, as shown in Figure 6 The method comprises the following steps S202 to S214:

[0085] S202: It is confirmed whether the bridge comprises two unit module bridge spans, if yes, step S204 is performed, and if no, step S212 is performed;

[0086] S204: One state of the track assembly in any unit module bridge span of the two unit module bridge spans is adjusted, the cushion block is placed on the main body of the erecting device, and the second track of the track assembly is supported by the cushion block;

[0087] S206: the first support keeps the height unchanged, and the second support is controlled to shrink in the direction towards the main body, so that the second support area rotates around the first support area in the direction towards the main body, and the height of the connecting end of the first track and the second track is lowered until the upper surfaces of the first track and the second track are flush, so that the other track assembly in any one of the two unit module bridge spans is adjusted to the first state;

[0088] S208: the state of the other track assembly in any one of the two unit module bridge spans is adjusted, and the pad is removed from the main body, so that the second track rotates in the direction away from the upper surface of the first track under the action of gravity until the lower surface of the first track is flush with the lower surface of the second track, so that the other track assembly in any one of the two unit module bridge spans is adjusted to the second state;

[0089] S210: the second track of the track assembly in the first state in one unit module bridge span is matched with the first track in the other unit module bridge span to obtain a bridge;

[0090] S212: the pad is removed from the main body, so that the second track rotates in the direction away from the upper surface of the first track under the action of gravity until the lower surface of the first track is flush with the lower surface of the second track, so that the track assembly in the unit module bridge span is adjusted to the second state;

[0091] S214: a fixing member is inserted between the first track and the second track to keep the first track and the second track relatively fixed to obtain a bridge.

[0092] In this embodiment, the method for erecting the bridge is further limited. The first track has a first support area and a second support area, and the support assembly is in contact with the first track at the first support area and the second support area, respectively. The support assembly includes a first support and a second support, the first support is used to contact the first support area, and the second support is used to contact the second support area. The second support area is located between the connecting end of the first track and the second track and the first support area. When the height of the connecting end of the first track and the second track of the track assembly is lowered by the support assembly, the specific working mode of the erecting device is as follows: first, the first support keeps the height unchanged, so that the height of the first support area remains unchanged, and then the second support is controlled to shrink in the direction towards the main body, so that the first support becomes a fulcrum, the second support area rotates around the first support area in the direction towards the main body, and the height of the connecting end of the first track and the second track is lowered.

[0093] By arranging the first support member and the second support member in the support assembly, and supporting the first support region of the first track by the first support member and supporting the second region of the first track by the second support member respectively, the height of the connecting end of the first track and the second track can be adjusted by adjusting the height of the second support member.

[0094] In one embodiment according to the present application, as shown in Figure 7 Fig. 3 shows a flowchart of a method for erecting a bridge according to an embodiment of the present application. The method comprises the following steps S302-S314:

[0095] S302: Determine whether the bridge comprises two unit module bridge spans, if yes, execute step S304, if no, execute step S312;

[0096] S304: Adjust the other state of the track assembly in any one of the two unit module bridge spans, place a pad between the hinge point of the first track and the end point of the second track away from the first track, and support the second track of the track assembly by the pad;

[0097] S306: Control the first support member to keep the height unchanged, control the second support member to contract in the direction towards the main body, so that the second support region rotates around the first support region in the direction towards the main body, to lower the height of the connecting end of the first track and the second track, until the upper surfaces of the first track and the second track are flush, to adjust one track assembly in any one of the two unit module bridge spans to the first state;

[0098] S308: Adjust the state of the other track assembly in any one of the two unit module bridge spans, remove the pad from the main body, so that the second track rotates in the direction away from the upper surface of the first track under the action of gravity, until the lower surface of the first track is flush with the lower surface of the second track, to adjust the other track assembly in any one of the two unit module bridge spans to the second state;

[0099] S310: Match the second track of the track assembly in the first state in one unit module bridge span with the first track in the other unit module bridge span, to obtain the bridge;

[0100] S312: Remove the pad from the main body, so that the second track rotates in the direction away from the upper surface of the first track under the action of gravity, until the lower surface of the first track is flush with the lower surface of the second track, to adjust the track assembly in the unit module bridge span to the second state;

[0101] S314: inserting a fixing member between the first track and the second track to keep the first track and the second track relatively fixed, to obtain the bridge.

[0102] In this embodiment, the method for erecting the bridge is further limited. The cushion block is used to support the second track, and the supporting position of the cushion block on the second track is between the hinge point of the first track and the second track and the end point of the second track away from the first track. Understandably, when the height of the hinge point of the first track and the second track is lowered, the first track drives the second track to rotate relative to the cushion block, and if the supporting position of the cushion block on the second track is at the end of the second track, it is easy to cause the second track to be unstable due to too large a rotation range, and if the supporting position of the cushion block on the second track is at the hinge point of the second track and the first track, it will cause the second track to be unable to rotate. The present application can keep the second track stable while ensuring the normal rotation of the second track by setting the supporting position of the cushion block on the second track between the hinge point of the first track and the second track and the end point of the second track away from the first track.

[0103] In an embodiment according to the present application, as shown in Figure 8 Fig. 4 shows a fourth flowchart of the method for erecting the bridge according to the embodiment of the present application. The method comprises the following steps S402 to S416:

[0104] S402: confirming whether the bridge comprises two unit module bridge spans, if yes, executing step S404, and if no, executing step S414;

[0105] S404: adjusting the state of one of the track assemblies in any one of the two unit module bridge spans, placing the cushion block between the hinge point of the first track and the second track and the end point of the second track away from the first track, and supporting the second track of the track assembly by the cushion block;

[0106] S406: controlling the first support member to keep the height unchanged, and controlling the second support member to shrink in the direction towards the main body, so that the second support region rotates around the first support region in the direction towards the main body, to lower the height of the connecting end of the first track and the second track, until the upper surfaces of the first track and the second track are flush, to adjust one of the track assemblies in any one of the two unit module bridge spans to the first state;

[0107] S408: adjusting the state of the other track assembly in any one of the two unit module bridge spans, removing the cushion block from the main body, so that the second track rotates in the direction away from the upper surface of the first track under the action of gravity, until the lower surface of the first track is flush with the lower surface of the second track, to adjust the other track assembly in any one of the two unit module bridge spans to the second state;

[0108] S410: inserting a fixing member between the first track and the second track to keep the first track and the second track relatively fixed, to obtain a track assembly in a first state;

[0109] S412: matching the second track of the track assembly in the first state in one unit module bridge span with the first track in another unit module bridge span, to obtain a bridge;

[0110] S414: removing the cushion block from the main body to make the second track rotate under the action of gravity in a direction away from the upper surface of the first track, until the lower surface of the first track is flush with the lower surface of the second track, to adjust the track assembly in the unit module bridge span to a second state;

[0111] S416: inserting a fixing member between the first track and the second track to keep the first track and the second track relatively fixed, to obtain a bridge.

[0112] In this embodiment, the method for erecting the bridge is further limited. After the upper surfaces of the first track and the second track are adjusted to be flush, the first track and the second track are fixed. Specifically, a fixing member is inserted between the first track and the second track, and the first track and the second track are fixedly connected by the fixing member, so as to keep the first track and the second track relatively fixed, to obtain a track assembly in a first state.

[0113] In a possible embodiment, the first track and the second track are both provided with connecting holes, and the fixing member is a bolt. The bolt is inserted into the connecting holes of the first track and the second track which overlap, to realize the fixed connection of the first track and the second track.

[0114] By inserting the fixing member between the first track and the second track, the first track and the second track can be fixedly connected by the fixing member, to avoid relative rotation between the first track and the second track.

[0115] In a possible embodiment, the unit module bridge span 210 is composed of two tracks (i.e. track assemblies 220) which are longitudinally connected by a long track and a short track (wherein the long track is the first track 221 and the short track is the second track 222), arranged in a central symmetric form, and composed of the unit module bridge span 210. When the bridge comprises a single unit module bridge span 210, both short tracks of the unit module bridge span 210 are flipped downward until the bottom surface of the short track (i.e. the lower surface 226 of the second track) is horizontally flush with the bottom surface of the long track (i.e. the lower surface 224 of the first track). When the bridge comprises two unit module bridge spans 210, and the combined bridge is erected by the two unit module bridge spans 210, the diagonally opposite short tracks at the joint need to be flipped upward so that the upper surface of the short track is horizontally flush with the upper surface of the long track, and then the joint at the upper part of the short track and the long track is connected by a pin (i.e. a fixing member). The erection device 100 is connected to the unit module bridge span 210 by a roller and a sliding groove connection, and the unit module bridge span 210 can be flipped synchronously with the erection device 100.

[0116] When the short track at the rear needs to be flipped upward, a cushion block 130 is placed on the lower deck of the short track at the rear (i.e. the main body 110), the erection mechanism (i.e. the support assembly 120) is flipped backward, the end of the short track is abutted against the cushion block 130, and the erection mechanism continues to flip until the short track is flipped upward and stopped when the upper surface of the short track is flush with the upper surface of the long track, and the joint at the upper part is connected.

[0117] The bridge erection method proposed in the present application has the following beneficial effects:

[0118] (1) The flipping of the short track is achieved without the need for a separate power mechanism;

[0119] (2) The cushion block 130 used is simple in structure and can be moved;

[0120] (3) The method reduces the overall weight of the erection device 100, reduces the space occupation of the vehicle deck, and saves costs.

[0121] The above is the preferred embodiment of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of protection of the present application.
