[0046] The utility model is described in detail below.

[0047] like Figure 1-Figure 6 As shown:

[0048] An adjustment connection mechanism for a bridge end of a double-wing horizontal rotation steel bridge, used for connecting the bridge end with an abutment 200; comprising an anchor hook 1 installed on an abutment foundation 300, a vertical adjustment mechanism 2 arranged at the bottom of the bridge 100 and hinged to the bridge 100, and a latch mechanism 3 arranged on the outer surface of the bridge 100 and plugged with the side of the abutment 200 close to the bridge end;

[0049] When the vertical adjustment mechanism 2 is arranged vertically, the end of the vertical adjustment mechanism 2 away from the bridge 100 will be engaged with the anchor hook 1, and the latch 311 will be connected with the abutment 200, so that the bridge 100 and the abutment 200 are connected to form a complete whole;

[0050] When it is necessary to connect the abutment 200 with the bridge end to realize land transportation:

[0051] First, the bridge 100 is adjusted so that the axis of the bridge 100 along the bridge direction is in the same straight line as the axis of the abutment 200; then the vertical adjustment mechanism 2 is started and converted to a vertical setting, and the end of the vertical adjustment mechanism 2 away from the bottom of the bridge 200 is engaged with the anchor hook 1 to achieve support between the bridge 100 and the abutment 200, and finally the latch mechanism 3 is inserted into the abutment 200 to complete the connection and fixation between the bridge 100 and the abutment 200;

[0052] The utility model can form a force-bearing whole in the vertical direction by setting a vertical adjustment mechanism 2, ensuring the stability of the vertical force. At the same time, the cooperation between the vertical adjustment mechanism 2 and the anchor hook 1 can effectively ensure that the top surface of the bridge 100 and the top surface of the abutment 200 are located on the same horizontal plane, thereby having the conditions for connecting the railway track and the train to pass, and realizing land transportation;

[0053] In some possible implementations, in order to ensure that the bridge 100 and the abutment 200 form a whole after being connected, the vertical force stability can be ensured;

[0054] The vertical adjustment mechanism 2 includes two groups of vertical adjustment devices 21 symmetrically arranged along the axis of the bridge 100 along the bridge direction, and the anchor hooks 1 are in two groups and are arranged corresponding to the two groups of vertical adjustment devices 21;

[0055] The vertical adjustment device 21 includes an articulated arm 211 with one end articulated to the bottom of the bridge 100, a telescopic driving mechanism 212 with one end articulated to the bottom of the bridge 100 and the other end articulated to the articulated arm 211, and a connecting shaft 213 arranged at the end of the articulated arm 211 away from the bridge 100 and cooperating with the anchor hook 1; the axis of the connecting shaft 213 is arranged along the transverse direction of the bridge;

[0056] The hinge point between the telescopic drive mechanism 212 and the articulated arm 211 is located between the connecting shaft 213 and the hinge point between the bridge 100 and the articulated arm 211 .

[0057] Furthermore, an articulated seat is provided at the bottom of the bridge 100, and the articulated arm 211 is articulated with the articulated seat through an articulated shaft, and the axis of the articulated shaft is arranged along the transverse direction of the bridge; an axis to which the telescopic driving mechanism 212 is articulated is provided on the articulated arm 211, and the axis is also arranged along the transverse direction of the bridge;

[0058] The bottom of the bridge 100 is provided with an articulated support, and the telescopic driving mechanism 212 and the articulated support are articulated through a hinge axis arranged along the transverse direction of the bridge;

[0059] In some possible implementations, in order to enable the two sets of telescopic driving mechanisms 212 to respectively control the corresponding articulated arms 211 to move, the connecting shaft 213 provided on the articulated arms 211 can cooperate with the positioning hole 11, so that the top surface of the bridge 100 and the top surface of the abutment 200 are on the same horizontal plane, meeting the needs of land transportation;

[0060] The two sets of telescopic drive mechanisms 212 are arranged between the two sets of articulated arms 211;

[0061] The anchor hook 1 is provided with a positioning hole 11 used in conjunction with the connecting shaft 213;

[0062] The center of the positioning hole 11, the hinge point of the hinge arm 211 and the bottom of the bridge 100 are on the same vertical plane;

[0063] The distance between the center of the positioning hole 11 and the top surface of the abutment 200 is H. When the articulated arm 211 is arranged vertically, the distance between the axis of the connecting shaft 213 and the top surface of the bridge 100 is L, H=L;

[0064] like Figure 4 As shown, when the abutment 200 is connected to the bridge 100, the telescopic driving mechanism 212 controls the articulated arm 211 to move clockwise, so that the connecting shaft 213 approaches the anchor hook 1. When the articulated arm 211 is vertically arranged, the connecting shaft 213 will be engaged with the anchor hook 1; thereby, the bridge 100 is supported vertically by the articulated arm 211.

[0065] When the articulated arm 211 is arranged vertically, the connecting shaft 213 will be located in the positioning hole 11, and the axes of the two will be arranged coaxially; since H=L, the top surface of the bridge 100 and the top surface of the abutment 200 are at the same horizontal elevation, and thus the top surface of the bridge 100 and the top surface of the abutment 200 are coplanar, thereby satisfying the requirement that the rails arranged on the abutment 200 and the bridge 100 can meet the rail connection requirement, so that the train can pass smoothly;

[0066] In some possible implementations, in order to effectively make the connecting shaft 213 engage with the positioning hole 11;

[0067] A guide groove 12 in an eight-shaped structure connected to the positioning hole 11 is provided on one side of the two groups of anchor hooks 1 close to each other; the small end of the guide groove 12 is connected to the positioning hole 11;

[0068] The guide groove 12 includes an upper curved surface 121 connected to the positioning hole 11, and a lower curved surface 122 that cooperates with the upper curved surface 121 to form an eight-shaped structure and is connected to the positioning hole 11. The lower curved surface 122 is arranged below the upper curved surface 121; the upper curved surface 121 and the lower curved surface 122 are both convex curved surfaces.

[0069] Specifically, when the top elevation of the bridge 100 is higher than the top elevation of the abutment 200, the connecting shaft 213 provided at the lower end of the articulated arm 211 will contact the upper curved surface 121, and the telescopic drive mechanism 212 will continue to work, and the connecting shaft 213 will slide down along the upper curved surface 121 until the center of the connecting shaft 213 coincides with the center of the positioning hole 11, and the telescopic drive mechanism 212 stops moving, thereby achieving the top surface of the bridge 100 and the top surface of the abutment 200 being coplanar;

[0070] When the top elevation of the bridge 100 is lower than the top elevation of the abutment 200, the connecting shaft 213 at the lower end of the articulated arm 211 contacts the lower adjustment curved surface 122 first, and when the telescopic drive mechanism 212 continues to work, the connecting shaft 213 rises along the lower curved surface 122 until the center of the connecting shaft 213 coincides with the center of the positioning hole 11, and the telescopic drive mechanism 212 stops moving, thereby achieving the coplanarity of the top surface of the bridge 100 and the top surface of the abutment 200;

[0071] Through the cooperation of the upper curved surface 121, the lower curved surface 122, the positioning hole 11 and the connecting shaft 213 in the utility model, it is effectively achieved that no matter what the height difference between the abutment 200 and the bridge deck is, after the center of the connecting shaft 213 set on the articulated arm 211 is controlled to coincide with the center of the positioning hole 11 through the telescopic drive mechanism 212, the articulated arm 211 will be in a completely vertical state; it can ensure that the abutment 200 and the bridge deck are at the same elevation, thereby having the conditions for connecting to the railway track and the passage of trains.

[0072] In some possible implementations, in order to effectively achieve the connection between the bridge 100 and the abutment 200;

[0073] The latch mechanism 3 includes two groups of latch devices 31 symmetrically arranged along the bridge axis of the bridge 100, and a fixed end slot 321 and a free end slot 322 arranged on the abutment 200 and used in conjunction with the two groups of latch devices 31 respectively; the fixed end slot 321 and the free end slot 322 are arranged on the side of the abutment 200 close to the bridge 100;

[0074] A free end fixing assembly used in conjunction with one set of latch devices 31 is arranged in the free end slot 322 , and a fixed end fixing piece used in conjunction with the other set of latch devices 31 is arranged in the fixed end slot 321 .

[0075] The free end fixing assembly includes two groups of free end support wheels 35 which are arranged vertically in parallel and form a through slot therebetween;

[0076] The fixed end fixing member comprises two sets of fixed end support wheels 33 arranged vertically and in parallel, and two sets of blocking wheels 34 arranged vertically and cooperating with the two sets of fixed end support wheels 33 to form a channel;

[0077] The axes of the free end support wheel 35 and the fixed end support wheel 33 are arranged along the transverse direction of the bridge; the axis of the blocking wheel 34 is arranged along the vertical direction;

[0078] Two sets of fixed support wheels and two sets of blocking wheels 34 are arranged in the fixed end slot 321; the four sets of wheels are close to each other to form a channel for the corresponding plug 311 to be inserted; after the plug 311 is inserted into the channel, the outer side surface of the plug 311 will contact and cooperate with the four sets of wheels, so that the plug 311 is limited in both vertical and horizontal directions, and ensures that the plug 311 has no lateral displacement when in the working state;

[0079] Only free end support wheels 35 are provided on the upper and lower sides of the latch pin 311 in the free end slot 322 to ensure that the vertical load can be borne in the working state; but the blocking wheel 34 is not provided, because the fixed end has already limited the bridge 100 laterally and no redundant limitation is required.

[0080] In some possible implementations,

[0081] The latch device 31 comprises a latch 311 which is slidably mounted on the outer surface of the bridge 100 and has one end inserted into the fixed end slot 321 through the channel or one end inserted into the free end slot 322 through the through slot, and a linear drive mechanism 312 which is connected to the end of the latch 311 away from the abutment 200 and is used to drive the latch 311 to perform linear motion along the bridge direction;

[0082] Furthermore, one end of the latch 311 away from the abutment 200 is hingedly matched with the linear drive mechanism 312, and two sets of symmetrical outer surfaces along the longitudinal direction of the bridge 100 are respectively provided with support guide rings 313 that are slidably matched with the latch 311; the latch 311 is sleeved in the support guide rings 313;

[0083] There are two groups of supporting one-way rings 312 arranged on each group of outer surfaces, and they are coaxially arranged;

[0084] Specifically, one end of the latch 311 away from the linear drive mechanism 312 is a wedge-shaped structure, so that the latch 311 can more easily enter the fixed end slot 321 or the free end slot 322 under the drive of the linear drive mechanism 312;

[0085] The linear drive mechanism 312 is a linear drive device in the prior art, such as a telescopic cylinder, a linear electric push rod, etc.; its telescopic section is connected to the side of the pin 311 away from the abutment 200; its internal structure is not described in detail here.

[0086] In the present invention, the contact and cooperation between the latch pin 311 and the fixed end support wheel 33, the free end support wheel 35 and the stop wheel 34 make the abutment 200 and the bridge 100 form a whole, and are capable of bearing the vertical load during the traffic process;

[0087] At the same time, the utility model can also maintain the tensile and compressive stress in the vertical direction through the telescopic drive mechanism 212, further protecting the dynamic load impact that may be caused during the passage, and playing the role of double insurance;

[0088] Since the bridge 100 needs to accommodate the passage of trains, the passing load is relatively large and may be accompanied by dynamic loads, the safety, reliability and operational stability of the entire device need to be fully considered; in this regard, the provision of an articulated arm 211 to withstand upper and lower dynamic loads is a secondary protection measure based on the force applied to the latch 311, making safety more reliable.

[0089] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
