Description

Technical Field

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

[0002] The bridge includes a rut assembly consisting of a long rut and a short rut. The short rut can rotate relative to the long rut. When erecting the bridge, it is often necessary to rotate the short rut upward to make the upper surfaces of the short rut and the long rut flush. The erection device in the related art is usually provided with a rotatable rod with a hook at the end, and a cylinder for driving the rod. The rod is driven by the cylinder to rotate and lift to lift the short rut. However, the structure of this erection device is complex, including many components, the overall weight is large, the space occupied is large, and the product cost is high. Summary of the invention

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

[0004] To this end, a first aspect of the present invention provides a mounting device.

[0005] A second aspect of the present invention provides a method for erecting a bridge.

[0006] To achieve at least one of the above purposes, the present invention provides an erection device, the erection device is used to erect a bridge, the bridge includes at least one unit module span, the unit module span includes a rutting assembly, the rutting assembly includes a first rutting and a second rutting, the first rutting and the second rutting are hinged, the rutting assembly can be switched between a first state and a second state, when the rutting assembly is in the first state, the upper surface of the first rutting is flush with the upper surface of the second rutting, when the rutting assembly is in the second state, the lower surface of the first rutting is flush with the lower surface of the second rutting, the erection device includes: a main body; a support assembly installed on the main body, the support assembly is used to support the first rutting and to adjust the second rutting The height of the connecting end between the first rut and the second rut; a pad block is removably placed on the main body, and the pad block is used to support the second rut; wherein, when the rut assembly needs to be adjusted to the first state, the pad block is placed on the main body and supports the second rut, and the supporting assembly lowers the height of the connecting end between the first rut and the second rut so that the first rut and the second rut rotate toward each other until the upper surface of the first rut is flush with the upper surface of the second rut; when the rut assembly needs to be adjusted to the second state, the pad block is removed from the main body so that the second rut rotates in a 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.

[0007] The erection device proposed in the present application is used for erecting a bridge, wherein the bridge includes one unit module span or two unit module spans, and any unit module span includes a rutting assembly, and the number of rutting assemblies in any unit module span is two, and the two rutting assemblies are arranged in a centrally symmetrical form. Any rutting assembly includes a first rutting and a second rutting, wherein the length of the first rutting is greater than the second rutting, the upper surface and the lower surface of the first rutting are two planes that are parallel or nearly parallel to each other, and there is an angle between the upper surface and the lower surface of the second rutting, and the angle is an acute angle. The two first ruttings of the two rutting assemblies in any unit module span are arranged diagonally, and the two second ruttings of the two rutting assemblies in any unit module span are arranged diagonally, that is, the two first ruttings in any unit module span are not adjacent, and the two second ruttings are not adjacent. When the bridge includes two unit module spans, the first rutting in one unit module span overlaps the second rutting in the other unit module span. The first rut is hinged to the second rut, specifically, the hinge point between 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 around the hinge point so that the rut assembly switches between the first state and the 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 mounting device can adjust the relative position between the first rut and the second rut so that the rut assembly switches between the first state and the second state.

[0008] Furthermore, the erection device includes a main body, a support assembly and a pad, wherein the support assembly is used to adjust the height of the connection end between the first rut and the second rut, and the pad is used to support the second rut. The support assembly is installed on the main body, and the support assembly can support the first rut and adjust the height of the connection end between the first rut and the second rut. The pad is removably placed on the main body, and the pad can be used to support the second rut or remove the second pad from the main body as needed.

[0009] Further, in the case where the erected bridge includes two unit module spans, one rut assembly in any unit module span is in the first state, and the other rut assembly is in the second state. When the two unit module spans are connected, the second rut in one rut assembly in the first state cooperates with the first rut in the other rut assembly in the second state, and the lower surface of the second rut cooperates with the upper surface of the first rut to form a bridge. In the case where the erected bridge includes only one unit module span, the rut assembly included in the unit module span is a rut assembly in the second state. Whether to use a pad is determined according to the required state of the rut assembly. Specifically, when the rut assembly needs to be adjusted to the first state, the pad is placed on the main body and supports the second rut, the second rut is supported by the pad, and then the support assembly lowers the height of the connecting end of the first rut and the second rut. Since the pad supports the second rut, when the height of the connection end between the first rut and the second rut is reduced, the pad generates a force on the second rut, and the first rut and the second rut rotate toward each other until the upper surface of the first rut is flush with the upper surface of the second rut, thereby obtaining a rut assembly in the first state. When the rut assembly needs to be adjusted to the second state, the pad is removed from the main body, and the second rut is no longer supported by the pad. Under the action of gravity, the second rut rotates 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, thereby obtaining a rut assembly in the second state.

[0010] By providing a pad block that can be removed from the main body in the erection device, the second rut can be supported or not supported by the pad block as needed, so that the relative position between the first rut and the second rut can be adjusted by the pad block, and there is no need to provide too many structures for adjusting the height of the second rut on the main body, which simplifies the structure of the erection device, reduces the installation space of the erection device, and reduces the cost of the erection device.

[0011] According to the above-mentioned erection device of the present invention, it can also have the following distinguishing technical features:

[0012] In some technical solutions, optionally, the first rut has a first support area and a second support area, the second support area is located between the connecting end of the first rut and the second rut and the first support area, the support assembly is capable of contacting 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 toward the main body to lower the height of the connecting end of the first rut and the second rut.

[0013] In this technical solution, the operation mode of the support assembly is defined. The support assembly supports the first rut and can adjust the height of the connecting end between 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, respectively, and supports the first rut. Among them, the second support area is located between the connecting end between the first rut and the second rut and the first support area. When it is necessary to lower the height of the connecting end between the first rut and the second rut, the height of the part of the support assembly in contact with the second support area is lowered, and at the same time, the height of the part of the support assembly in contact with the first support area remains unchanged. In this way, the second support area can be rotated around the first support area in a direction toward the main body, thereby lowering the height of the connecting end between the first rut and the second rut.

[0014] By arranging the support assembly to be able to contact the 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 portion where the support assembly contacts the two areas.

[0015] In some technical schemes, optionally, the support assembly includes: a first support member, installed on the main body, and the first support member is used to contact the first support area; a second support member, installed on the main body, and the second support member is used to contact the second support area. When the rut assembly needs to be adjusted to the first state, the first support member maintains a constant height, and the second support member contracts in a direction toward the main body so that the second support area rotates around the first support area in a direction toward the main body to lower the height of the connecting end of the first rut and the second rut.

[0016] In this technical solution, the structure of the support assembly is defined. The support assembly includes a first support member and a second support member, both of which are installed on the main body, wherein the first support member is used to contact the first support area, and the second support member is used to contact the second support area. The second support member can be extended and retracted relative to the main body to adjust the height of the connection end between the first rut and the second rut. Specifically, when the rut assembly needs to be adjusted to the first state, the first support member maintains a constant height, and the second support member contracts in the direction toward the main body, so that the first support member can become a fulcrum, and the second support area can rotate around the first support area in the direction toward the main body, thereby reducing the height of the connection end between the first rut and the second rut.

[0017] By arranging a first support member and a 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 technical solutions, optionally, the pad can be supported in a supporting area of ​​the second rut, and the supporting area is located between a hinge point between the first rut and the second rut and an end point of the second rut away from the first rut.

[0019] In this technical solution, the setting position of the pad is limited. Specifically, the pad can be supported on the support area of ​​the second rut, and the support area is located between the hinge point between 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 hinge point between the first rut and the second rut is reduced, the first rut drives the second rut to rotate relative to the pad. If the support position of the pad for the second rut is located at the end of the second rut, it is easy to cause the second rut to be unstable due to the large rotation range. If the support position of the pad for the second rut is located at the hinge point between the second rut and the first rut, it will cause the second rut to be unable to rotate. The present application sets the support position of the pad for the second rut between the hinge point between the first rut and the second rut and the end point of the second rut away from the first rut, so as to ensure the normal rotation of the second rut while keeping the second rut stable.

[0020] The second aspect of the present invention further proposes a method for erecting a bridge, which is performed by the erection device as proposed in the first aspect of the present invention. The method for erecting a bridge includes: confirming whether the bridge includes two unit module spans; if the bridge includes two unit module spans, adjusting the state of a wheel track assembly in any unit module span of the two unit module spans, placing a pad on the main body of the erection device, and supporting the second wheel track of the wheel track assembly through the pad; lowering the height of the connecting end of the first wheel track and the second wheel track of the wheel track assembly through the supporting assembly until the upper surfaces of the first wheel track and the second wheel track are flush, so as to connect the two unit module spans. A rut assembly in any unit module span in the span is adjusted to the first state; the state of another rut assembly in any unit module span of the two unit module spans is adjusted, and the pad is removed from the main body so that the second rut rotates in a 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 in any unit module span of the two unit module spans to the second state; the second rut of the rut assembly in the first state in one unit module span is matched with the first rut in the other unit module span to obtain a bridge.

[0021] The bridge erection method proposed in the present application is used in an erection device, and the erection device adopts the bridge erection method to erect a bridge. First, it is confirmed that the bridge includes a single unit module span or two unit module spans. If the bridge includes two unit module spans, it is necessary to adjust one rut assembly in any unit module span to a first state, and the other rut assembly to a second state, and then match the second rut in one rut assembly in the first state with the first rut in another rut assembly in the second state, so that the lower surface of the second rut matches the upper surface of the first rut to form a bridge.

[0022] Specifically, if the bridge includes two unit module spans, the state of a rut assembly in any of the two unit module spans is adjusted to be a rut assembly in the first state. First, a pad is placed on the main body of the erection device, and the second rut of the rut assembly is supported by the pad. Then, the height of the connection end of the first rut and the second rut of the rut assembly is lowered by the support assembly until the upper surface of the first rut is flush with the upper surface of the second rut, so as to adjust a rut assembly in any of the two unit module spans to the first state.

[0023] Furthermore, after adjusting one rut assembly in any one of the two unit module spans to the first state, the other rut assembly in any one of the two unit module spans is adjusted to be 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 a 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 other rut assembly in any one of the two unit module spans is adjusted to the second state.

[0024] Further, after adjusting the two rut components in any unit module span to the first state and the second state respectively, the second rut of the rut component in the first state in one unit module span is matched with the first rut in another unit module span to obtain the bridge. Specifically, since there is an angle between the upper surface and the lower surface of the second rut, and the angle is an acute angle, the lower surface of the second rut in the rut component in the first state is an inclined surface, and the upper surface of the first rut is an inclined surface, and the two inclined surfaces are adapted to each other. When combining the two unit module spans, the lower surface of the second rut in the rut component in the first state in one unit module span is fitted with the upper surface of the first rut in the other unit module span, and the lower surface of the second rut in the rut component in the second state is flush with the lower surface of the first rut, and can be fitted to the ground or other countertops to obtain a bridge.

[0025] By adopting the bridge erection method to erect a bridge, the second rut can be supported or not supported by the pad as needed, so that the relative position between the first rut and the second rut can be adjusted by the pad, and there is no need to set too many structures for adjusting the height of the second rut on the main body, which simplifies the structure of the erection device and reduces the installation space of the erection device.

[0026] In some technical schemes, optionally, the support assembly includes a first support member and a second support member, the first support member is used to contact the first support area of ​​the first rut, the second support member is used to contact the second support area of ​​the first rut, the second support area is located between the connecting end of the first rut and the second rut and the first support area, and the height of the connecting end of the first rut and the second rut of the rut assembly is lowered by the support assembly, specifically: the first support member is controlled to maintain a constant height, and the second support member is controlled to shrink in a direction toward the main body so that the second support area rotates around the first support area in a direction toward the main body to lower the height of the connecting end of the first rut and the second rut.

[0027] In this technical solution, the method for erecting a bridge is further defined. The first rut has a first support area and a second support area, the support assembly contacts the first rut in the first support area and the second support area respectively, the support assembly includes a first support member and a second support member, the first support member is used to contact the first support area, and the second support member is used to contact the second support area. 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. When the height of the connecting end of the first rut and the second rut of the rut assembly is lowered by the support assembly, the specific working method of the erection device is as follows: first, the first support member is controlled to maintain a constant height, so that the height of the first support area can be kept constant, and then the second support member is controlled to shrink in the direction toward the main body, so that the first support member can become a fulcrum, so that the second support area rotates around the first support area in the direction toward the main body, and then the height of the connecting end of the first rut and the second rut is reduced.

[0028] By arranging a first support member and a 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.

[0029] In some technical solutions, optionally, a pad is placed on the main body of the erection device, specifically: the pad is placed between the hinge point between the first rut and the second rut and the end point of the second rut away from the first rut.

[0030] In this technical solution, the method for erecting a bridge is further defined. The pad is used to support the second rut, and the support position of the pad for the second rut is located between the hinge point between the first rut and the second rut and the end point of the second rut away from the first rut. It is understandable that when the height of the hinge point between the first rut and the second rut is reduced, the first rut drives the second rut to rotate relative to the pad. If the support position of the pad for the second rut is located at the end of the second rut, it is easy to cause the second rut to be unstable due to the large rotation range. If the support position of the pad for the second rut is located at the hinge point between the second rut and the first rut, it will cause the second rut to be unable to rotate. The present application sets the support position of the pad for the second rut between the hinge point between the first rut and the second rut and the end point of the second rut away from the first rut, so as to ensure the normal rotation of the second rut while keeping the second rut stable.

[0031] In some technical solutions, optionally, after the upper surfaces of the first rut and the second rut are flush, the method further includes: 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 a rut assembly in a first state.

[0032] In the technical solution, the bridge erection method is further defined. 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 relatively fixed, and a rut assembly in a first state is obtained.

[0033] In a possible technical solution, connection holes are provided on the first rut and the second rut, and the fixing member is a latch, which is inserted into the overlapping connection holes on the first rut and the second rut to achieve fixed connection between the first rut and the second rut.

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

[0035] In some technical schemes, optionally, the method of erecting a bridge also includes: if the bridge includes a single unit module span, the pad is removed from the main body so that the second rut rotates in a 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 rut assembly in the unit module span to the second state.

[0036] In this technical solution, the method for erecting a bridge is further defined. Confirm that the bridge includes a single unit module span or two unit module spans. If the bridge includes a single unit module span, adjust the lower surfaces of the first rut and the second rut of the rut assembly in the unit module span to be flush, that is, adjust the rut assembly in the unit module span to the second state. First, remove the pad from the main body, and no longer support the second rut through the pad, 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 unit module 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, thereby obtaining a bridge.

[0038] In this technical solution, the method for erecting a bridge is further defined. After the rut assembly in a single unit module 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 remain relatively fixed, thereby obtaining a rut assembly in the second state, and the unit module span including the rut assembly in the second state constitutes a bridge.

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

[0040] Additional aspects and advantages of the present invention will become apparent from the following description or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The erection device 100 proposed in this application is used for erecting a bridge. Figure 3 As shown, the bridge includes one unit module span 210 or two unit module spans 210, and any unit module span 210 includes a rutting assembly 220. The number of rutting assemblies 220 in any unit module span 210 is two. Figure 2 As shown, the two rut assemblies 220 are arranged in a centrally symmetrical form.

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 between the first rut 221 and the second rut 222. The pad 130 is removably placed on the main body 110, and the second rut 222 can be supported by the pad 130 or the second pad 130 can be removed from the main body 110 as needed.

[0059] Further, in the case where the erected bridge includes two unit module spans 210, one rut assembly 220 in any unit module span 210 is in the first state, and the other rut assembly 220 is in the second state. When the two unit module spans 210 are connected, the second rut 222 in one rut assembly 220 in the first state cooperates with the first rut 221 in the other rut assembly 220 in the second state, and the lower surface 226 of the second rut cooperates with the upper surface 223 of the first rut to form a bridge. In the case where the erected bridge includes only one unit module span 210, the rut assembly 220 included in the unit module span 210 is the rut assembly 220 in the second state. Whether to use the pad 130 is determined according to the required state of the rut assembly 220. Specifically, when the rut assembly 220 needs to be adjusted to the first state, the pad 130 is placed on the main body 110 and supports the second rut 222. The second rut 222 is supported by the pad 130, and then the support assembly 120 lowers the height of the connection end between the first rut 221 and the second rut 222. Since the pad 130 supports the second rut 222, when the height of the connection end between the first rut 221 and the second rut 222 is lowered, the pad 130 generates a force on the second rut 222, and the first rut 221 and the second rut 222 rotate toward each other until the upper surface 223 of the first rut is flush with the upper surface 225 of the second rut, thereby obtaining the rut assembly 220 in the first state. When the rut assembly 220 needs to be adjusted to the second state, the pad 130 is removed from the main body 110, and the second rut 222 is no longer supported by the pad 130. The second rut 222 rotates in a direction away from the upper surface 223 of the first rut under the action of gravity until the lower surface 224 of the first rut is flush with the lower surface 226 of the second rut, thereby obtaining the rut assembly 220 in the second state.

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

[0061] In some embodiments, optionally, the first rut 221 has a first support area and a second support area, the second support area is located between the connecting end of the first rut 221 and the second rut 222 and the first support area, the support assembly 120 is capable of contacting the first support area and the second support area, and the support assembly 120 controls the second support area to rotate around the first support area in a direction toward the main body 110 to lower the height of the connecting end of the first rut 221 and the second rut 222.

[0062] In this embodiment, the operation mode of the support assembly 120 is defined. The support assembly 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 area and a second support area. The support assembly 120 contacts the first rut 221 in the first support area and the second support area, respectively, and supports the first rut 221. Among them, the second support area is located between the connection end between the first rut 221 and the second rut 222 and the first support area. When it is necessary to reduce the height of the connection end between the first rut 221 and the second rut 222, the height of the part of the support assembly 120 that contacts the second support area is reduced, and the height of the part of the support assembly 120 that contacts the first support area remains unchanged. In this way, the second support area can be rotated 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.

[0063] By arranging the support assembly 120 to be in contact with 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 portion where the support assembly 120 contacts the two areas.

[0064] In some embodiments, optionally, Figure 1 As shown, the support assembly 120 includes: a first support member 121, which is installed on the main body 110, and the first support member 121 is used to contact the first support area; a second support member 122, which is installed on the main body 110, and the second support member 122 is used to contact the second support area. When it is necessary to adjust the rut assembly 220 to the first state, the first support member 121 maintains a constant height, and the second support member 122 shrinks 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, so as to reduce the height of the connecting end of 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 includes a first support member 121 and a second support member 122, both of which are installed on the main body 110, wherein the first support member 121 is used to contact the first support area, and the second support member 122 is used to contact the second support area. The second support member 122 can be extended and retracted relative to the main body 110 to adjust the height of the connection end between the first rut 221 and the second rut. Specifically, when it is necessary to adjust the rut assembly 220 to the first state, the first support member 121 maintains a constant height, and the second support member 122 shrinks in the direction toward the main body 110, so that the first support member 121 can become a fulcrum, 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.

[0066] By arranging the first support member 121 and the second support member 122 in the support assembly 120, and supporting the first support area of ​​the first rut 221 by the first support member 121 and supporting the second area of ​​the first rut 221 by the second support member 122, the height of the connecting end of the first rut 221 and the second rut 222 can be adjusted by adjusting the height of the second support member 122.

[0067] In some embodiments, optionally, the pad 130 can be supported in a supporting area of ​​the second rut 222 , where the supporting area is located between a hinge point between the first rut 221 and the second rut 222 and an end point of the second rut 222 away from the first rut 221 .

[0068] In this embodiment, the setting position of the pad 130 is limited. Specifically, the pad 130 can be supported in the support area of ​​the second rut 222, and the support area is located between the hinge point of the first rut 221 and the second rut 222 and the end point of the second rut 222 away from the first rut 221. It can be understood that when the height of the hinge point of the first rut 221 and the second rut 222 is reduced, the first rut 221 drives the second rut 222 to rotate relative to the pad 130. If the support position of the pad 130 for the second rut 222 is located at the end of the second rut 222, it is easy to cause the second rut 222 to be unstable due to the excessive rotation range. If the support position of the pad 130 for the second rut 222 is located at the hinge point of the second rut 222 and the first rut 221, it will cause the second rut 222 to be unable to rotate. The present application sets the support position of the pad 130 for the second rut 222 between the hinge point between the first rut 221 and the second rut 222 and the end point of the second rut 222 away from the first rut 221 , so that the second rut 222 can be kept stable while ensuring the normal rotation of the second rut 222 .

[0069] A second aspect of the present invention provides a method for erecting a bridge, which is performed by the erection device provided in any of the above embodiments, such as Figure 5 As shown, the figure shows one of the flow charts of the bridge erection method according to an embodiment of the present invention. The erection method includes the following steps S102 to S110:

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

[0071] S104: adjusting a state of a rutting assembly of any unit module bridge span of the two unit module bridge spans, placing a pad on the main body of the erection device, and supporting a second rutting of the rutting assembly through the pad;

[0072] S106: lowering the height of the connection end between the first rut and the second rut of the rut assembly by the support assembly until the upper surfaces of the first rut and the second rut are flush, so as to adjust a rut assembly in any unit module span of the two unit module spans to the first state;

[0073] S108: adjusting the state of the other rut assembly in any one of the two unit module bridge spans, removing the pad from the main body, so that the second rut rotates in a 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 in any one of the two unit module bridge spans to the second state;

[0074] S110: matching a second rut of a rut assembly in a first state in a unit module bridge span with a first rut in another unit module bridge span to obtain a bridge;

[0075] S112: removing the pad from the main body, so that the second rut rotates in a 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 rut assembly in the unit module bridge span to the second state;

[0076] S114: inserting a fixing member between the first rut and the second rut to keep the first rut and the second rut relatively fixed, thereby obtaining a bridge.

[0077] The bridge erection method proposed in the present application is used in an erection device, and the erection device adopts the bridge erection method to erect the bridge. First, confirm that the bridge includes a single unit module span or two unit module spans. If the bridge includes two unit module spans, it is necessary to adjust one rut assembly in any unit module span to the first state, and the other rut assembly to the second state, and then match the second rut in a rut assembly in the first state with the first rut in another rut assembly in the second state, so that the lower surface of the second rut matches the upper surface of the first rut to form a bridge. Specifically, if the bridge includes two unit module spans, adjust the state of a rut assembly in any unit module span of the two unit module spans to a rut assembly in the first state. First, place a pad on the main body of the erection device, and support the second rut of the rut assembly through the pad. Then, the height of the connection end between the first rut and the second rut of the rut assembly is lowered by the support assembly until the upper surfaces of the first rut and the second rut are flush, so as to adjust a rut assembly in any unit module span of the two unit module spans to the first state.

[0078] Furthermore, after adjusting one rut assembly in any one of the two unit module spans to the first state, the other rut assembly in any one of the two unit module spans is adjusted to be 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 a 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 other rut assembly in any one of the two unit module spans is adjusted to the second state.

[0079] Furthermore, after adjusting the two rut components in any unit module span to the first state and the second state respectively, the second rut of the rut component in the first state in one unit module span is matched with the first rut in another unit module span to obtain the bridge. Specifically, since there is an angle between the upper surface and the lower surface of the second rut, and the angle is an acute angle, the lower surface of the second rut in the rut component in the first state is an inclined surface, and the upper surface of the first rut is an inclined surface, and the two inclined surfaces are adapted to each other. When combining the two unit module spans, the lower surface of the second rut in the rut component in the first state in one unit module span is fitted with the upper surface of the first rut in the other unit module span, and the lower surface of the second rut in the rut component in the second state is flush with the lower surface of the first rut, and can be fitted to the ground or other surfaces to obtain a bridge.

[0080] By adopting the bridge erection method to erect a bridge, the second rut can be supported or not supported by the pad as needed, so that the relative position between the first rut and the second rut can be adjusted by the pad, and there is no need to set too many structures for adjusting the height of the second rut on the main body, which simplifies the structure of the erection device and reduces the installation space of the erection device.

[0081] Further, if the bridge includes a single unit module span, the lower surfaces of the first rut and the second rut of the rut assembly in the unit module span are adjusted to be flush, that is, the rut assembly in the unit module span is adjusted to the second state. First, the pad is removed from the main body, and the second rut is no longer supported by the pad, so that the second rut can rotate in a 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 unit module span is adjusted to the second state.

[0082] After the rut assembly in the single unit module 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 relatively fixed, and the rut assembly in the second state is obtained, and the unit module span including the rut assembly in the second state constitutes a bridge.

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

[0084] In one embodiment of the present application, the support assembly includes a first support member and a second support member, the first support member is used to contact a first support area of ​​the first rut, the second support member is used to contact a second support area of ​​the first rut, and the second support area is located between the connecting end of the first rut and the second rut and the first support area. Figure 6 As shown, the figure shows a second flow chart of the method for erecting a bridge according to an embodiment of the present invention. The method includes the following steps S202 to S214:

[0085] S202: confirm whether the bridge includes two unit module spans, if yes, execute step S204, if no, execute step S212;

[0086] S204: adjusting a state of a rutting assembly of any one of the two unit module spans, placing a pad on the main body of the erection device, and supporting a second rutting of the rutting assembly through the pad;

[0087] S206: Control the first support member to maintain a constant height, and control the second support member to shrink in a direction toward the main body, so that the second support area rotates around the first support area in a direction toward the main body, so as to reduce the height of the connecting end of the first rut and the second rut until the upper surfaces of the first rut and the second rut are flush, so as to adjust the other rut assembly in any unit module span of the two unit module spans to the first state;

[0088] S208: adjusting the state of the other rut assembly in any one of the two unit module bridge spans, removing the pad from the main body, so that the second rut rotates in a 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 in any one of the two unit module bridge spans to the second state;

[0089] S210: matching a second rut of a rut assembly in a first state in a unit module bridge span with a first rut in another unit module bridge span to obtain a bridge;

[0090] S212: removing the pad from the main body, so that the second rut rotates in a 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 rut assembly in the unit module bridge span to the second state;

[0091] S214: inserting a fixing member between the first rut and the second rut to keep the first rut and the second rut relatively fixed, thereby obtaining a bridge.

[0092] In this embodiment, the method for erecting a bridge is further defined. The first rut has a first support area and a second support area, the support assembly contacts the first rut in the first support area and the second support area respectively, the support assembly includes a first support member and a second support member, the first support member is used to contact the first support area, and the second support member is used to contact the second support area. 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. When the height of the connecting end of the first rut and the second rut of the rut assembly is lowered by the support assembly, the specific working method of the erection device is as follows: first, the first support member is controlled to maintain a constant height, so that the height of the first support area can be kept constant, and then the second support member is controlled to shrink in the direction toward the main body, so that the first support member can become a fulcrum, so that the second support area rotates around the first support area in the direction toward the main body, and then the height of the connecting end of the first rut and the second rut is reduced.

[0093] By arranging a first support member and a 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.

[0094] In one embodiment according to the present application, Figure 7 As shown, the figure shows a third flow chart of the method for erecting a bridge according to an embodiment of the present invention. The method includes the following steps S302 to S314:

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

[0096] S304: adjusting another state of the rut assembly of any unit module bridge span of the two unit module bridge spans, placing a pad between a hinge point between the first rut and the second rut and an end point of the second rut away from the first rut, and supporting the second rut of the rut assembly by the pad;

[0097] S306: Control the first support member to maintain a constant height, and control the second support member to shrink in a direction toward the main body, so that the second support area rotates around the first support area in a direction toward the main body, so as to reduce the height of the connecting end of the first rut and the second rut until the upper surface of the first rut is flush with the upper surface of the second rut, so as to adjust a rut assembly in any unit module span of the two unit module spans to the first state;

[0098] S308: adjusting the state of the other rut assembly in any one of the two unit module bridge spans, removing the pad from the main body, so that the second rut rotates in a 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 in any one of the two unit module bridge spans to the second state;

[0099] S310: Matching a second rut of a rut assembly in a first state in a unit module bridge span with a first rut in another unit module bridge span to obtain a bridge;

[0100] S312: removing the pad from the main body, so that the second rut rotates in a 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 rut assembly in the unit module bridge span to the second state;

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

[0102] In this embodiment, the method for erecting the bridge is further defined. The pad is used to support the second rut, and the support position of the pad for the second rut is located between the hinge point between the first rut and the second rut and the end point of the second rut away from the first rut. It can be understood that when the height of the hinge point between the first rut and the second rut is reduced, the first rut drives the second rut to rotate relative to the pad. If the support position of the pad for the second rut is located at the end of the second rut, it is easy to cause the second rut to be unstable due to the large rotation range. If the support position of the pad for the second rut is located at the hinge point between the second rut and the first rut, it will cause the second rut to be unable to rotate. The present application sets the support position of the pad for the second rut between the hinge point between the first rut and the second rut and the end point of the second rut away from the first rut, so as to ensure the normal rotation of the second rut while keeping the second rut stable.

[0103] In one embodiment according to the present application, Figure 8 As shown, the figure shows a fourth flow chart of the method for erecting a bridge according to an embodiment of the present invention. The method includes the following steps S402 to S416:

[0104] S402: confirm whether the bridge includes two unit module spans, if yes, execute step S404, if no, execute step S414;

[0105] S404: adjusting a state of a rut assembly of any unit module bridge span of the two unit module bridge spans, placing a pad between a hinge point of the first rut and the second rut and an end point of the second rut away from the first rut, and supporting the second rut of the rut assembly by the pad;

[0106] S406: Control the first support member to maintain a constant height, and control the second support member to shrink in a direction toward the main body, so that the second support area rotates around the first support area in a direction toward the main body, so as to reduce the height of the connecting end of the first rut and the second rut until the upper surface of the first rut is flush with the upper surface of the second rut, so as to adjust a rut assembly in any unit module span of the two unit module spans to the first state;

[0107] S408: adjusting the state of the other wheel track assembly in any one of the two unit module bridge spans, removing the pad from the main body, so that the second wheel track rotates in a direction away from the upper surface of the first wheel track under the action of gravity, until the lower surface of the first wheel track is flush with the lower surface of the second wheel track, so as to adjust the other wheel 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 rut and the second rut to keep the first rut and the second rut relatively fixed, thereby obtaining a rut assembly in a first state;

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

[0110] S414: removing the pad from the main body, so that the second rut rotates in a 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 rut assembly in the unit module bridge span to the second state;

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

[0112] In this embodiment, the bridge erection method is further defined. 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 remain relatively fixed, and a rut assembly in a first state is obtained.

[0113] In a possible embodiment, connection holes are provided on the first rut and the second rut, and the fixing member is a pin, which is inserted into the overlapping connection holes on the first rut and the second rut to achieve fixed connection between the first rut and the second rut.

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

[0115] In a possible embodiment, the unit module span 210 is composed of two ruts (i.e., rut assembly 220), which are respectively connected longitudinally by long and short ruts (wherein the long rut is the first rut 221, and the short rut is the second rut 222), arranged in a central symmetric form, and constitute the unit module span 210. When the bridge includes a single unit module span 210, the two short ruts of the rut in the unit module span 210 are both turned downward until the bottom surface of the short rut (i.e., the lower surface 226 of the second rut) is flush with the bottom surface of the long rut (i.e., the lower surface 224 of the first rut). When the bridge includes two unit module spans 210, when a combined bridge is erected by two unit module spans 210, the two short ruts diagonally opposite to each other at the joint need to be turned upward so that the upper surface of the short rut is flush with the upper surface of the long rut, and then the joints of the upper parts of the short rut and the long rut are connected by a pin (i.e., a fixing member). The erection device 100 is connected to the unit module span 210 by roller and slide groove connection, and the unit module span 210 can be turned over synchronously with the erection device 100 .

[0116] When the short wheel track at the rear needs to be flipped upward, a pad 130 is placed on the lower roof deck (i.e., the main body 110) of the short wheel track at the rear, and the erection mechanism (i.e., the support assembly 120) is flipped backward, and the end of the short wheel track is pressed against the pad 130. After the erection mechanism continues to flip, the short wheel track is pressed and flipped upward, and stops when it is flush with the upper panel of the long wheel track, and the upper joint is connected.

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

[0118] (1) No separate power mechanism is required to achieve short rut flipping;

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

[0120] (3) This method reduces the overall weight of the mounting device 100, reduces the space occupied by the vehicle deck, and saves costs.

[0121] The above are preferred embodiments 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 of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
