Description

Technical Field

[0001] The invention belongs to the technical field of connecting joints, and in particular relates to a vertical plate pin joint. Background Art

[0002] In terms of working mode, the ear plate in the traditional plate pin joint works by extending in a straight line or by rotating in a vertical plane. As the size of the structure increases, the size of the traditional plate pin joint will also increase, which not only makes it difficult to extend the ear plate, but also makes it difficult to insert and remove the fixing pin, and even requires the use of an external power source. In terms of the force bearing mode of the joint, most traditional plate pin joints mainly bear the tensile pressure generated by the longitudinal relative movement between the two connected structures, but less bear the shear force generated by the vertical or horizontal relative movement between the structures. These two shortcomings of traditional plate pin joints limit the application prospects of plate pin joints. Summary of the invention

[0003] In view of this, the present invention provides a vertical plate-pin joint, which consists of two major parts: one is a transmission mechanism for realizing horizontal rotation and extension of the ear plate, and the other is a pry rod mechanism for realizing vertical insertion and extraction of the fixing pin; the connection between the ear plate and the fixing pin is realized by the connection between the two structures to be connected, and has the characteristics of convenient operation, large load-bearing capacity and wide application range.

[0004] The present invention is achieved through the following technical solutions:

[0006] The transmission mechanism is installed in the structure A to be connected; the pry bar mechanism is installed in the structure B to be connected; when the transmission mechanism and the pry bar mechanism are connected, the connection between the structure A and the structure B is achieved;

[0007] The transmission mechanism comprises: an ear plate, a first double ear seat, a transmission shaft and a transmission fork;

[0008] The first double-ear seat is fixed in the structure A; two ears of the first double-ear seat are processed with coaxial through holes A;

[0009] One end of the transmission shaft is installed in the through hole A of the first double-ear seat;

[0010] The two ends of the ear plate are respectively processed with a connecting hole A and a connecting hole B; one end of the ear plate is located between the two supporting ears of the first double-ear seat, and is connected to the transmission shaft located in the first double-ear seat through the connecting hole A, and the ear plate can rotate synchronously with the transmission shaft; the other end of the ear plate extends out of the first double-ear seat;

[0011] A transmission fork is installed at the other end of the transmission shaft, and the transmission shaft can be driven to rotate by toggling the transmission fork;

[0012] When the transmission fork is in the storage position, the ear plate is located in the structure A; when the transmission fork is in the working position, the ear plate is horizontally rotated out and extends out of the structure A;

[0013] The pry bar mechanism comprises: a second double-ear seat, a fixing pin, a pull rod, a pry bar sleeve and a bracket;

[0014] The second double-ear seat is fixed in the structure B; two ears of the second double-ear seat are processed with coaxial through holes B, and a guide sleeve coaxial with the through hole B is provided on the outer surface of the second double-ear seat;

[0015] The bracket is fixed in structure B;

[0016] The pry bar sleeve is an L-shaped rod; the inflection point of the L-shaped rod is connected to the bracket through a bolt, and the pry bar sleeve can rotate around the axis of the bolt;

[0017] One end of the pull rod is pin-connected to one end of the pry rod sleeve; the other end of the pull rod is pin-connected to one end of the fixing pin; the other end of the fixing pin extends into the guide sleeve of the second double-ear seat;

[0018] When the fixing pin is in the storage position, the fixing pin does not enter the through hole B of the second double-ear seat; when the fixing pin is in the working position, the fixing pin enters the through hole B of the second double-ear seat;

[0019] When the transmission mechanism and the pry bar mechanism are connected, the end of the ear plate extending from the structure A extends between the two ears of the second double-ear seat, and the connecting hole B of the ear plate is coaxial with the through hole B of the second double-ear seat; the fixing pin enters into the through hole B and the connecting hole B to realize the connection between the ear plate and the fixing pin B, thereby realizing the connection between the transmission mechanism and the pry bar mechanism.

[0020] Furthermore, it also includes a limiting device; the limiting device is installed in the structure A and is used to limit the storage position and the working position of the transmission fork respectively.

[0022] Furthermore, the bracket is fixed in the structure B by welding.

[0023] Beneficial effects: (1) The present invention utilizes the lever principle to realize the vertical insertion and extraction of the fixing pin and the rotation and extension of the ear plate, which, on the one hand, reduces the labor intensity of manually operating the plate pin joint, and on the other hand, enables the fixing pin to achieve self-locking. This method can more easily insert and extract the fixing pin when there is a large force between the structures, fully reflecting the advantage of the convenient operation of the vertical plate pin joint.

[0024] (2) The ear plate of the present invention is extended by rotation in a horizontal plane, so that the ear plate is well protected during the assembly process, and the ear plate and the fixing pin are arranged inside the structure to prevent them from being disturbed by external forces, thereby achieving good protection of the plate-pin joint.

[0025] (3) The transmission mechanism and the pry rod mechanism of the present invention both have a first double-ear seat and a second double-ear seat for supporting the ear plate, so that the ear plate can withstand tension and shear force at the same time, thereby increasing the ability of the plate-pin joint to adapt to complex load conditions and improving the bearing capacity of the plate-pin joint.

[0026] (4) Since the lengths of the ear plate, the transmission shaft and the pull rod of the present invention can be changed with the change of the structure, by adjusting the lengths of the transmission shaft and the pull rod, and the cross-sectional area of ​​the ear plate, it can adapt to structures of different sizes, and has a wide range of applications.

[0042] The two ends of the ear plate 1 are respectively processed with a connection hole A and a connection hole B; the ear plate 1 is arranged in the horizontal direction; one end of the ear plate 1 is located between the two supporting ears of the first double-ear seat 2, and is connected to the transmission shaft 3 located in the first double-ear seat 2 through the connection hole A, and the ear plate 1 can rotate synchronously with the transmission shaft 3; the other end of the ear plate 1 extends out of the first double-ear seat 2;

[0043] The other end of the transmission shaft 3 is provided with a transmission fork 4, and the transmission shaft 3 can be driven to rotate by shifting the transmission fork 4;

[0044] When the transmission fork 4 is in the storage position, the ear plate 1 is located in the structure A; when the transmission fork 4 is in the working position, the ear plate 1 is horizontally rotated out and extends out of the structure A;

[0045] The limiting device 5 is installed in the structure A and is used to limit the storage position and the working position of the transmission fork 4 respectively;

[0046] See attached Figure 4-7 The pry bar mechanism comprises: a second double-ear seat 10, a fixing pin 6, a pull rod 7, a pry bar sleeve 8 and a bracket 9;

[0047] The second double-ear seat 10 is fixed in the structure B; coaxial through holes B are processed on the two supporting ears of the second double-ear seat 10, and a guide sleeve coaxial with the through hole B is provided on the outer surface of the second double-ear seat 10; the axis of the through hole B is arranged along the vertical direction;

[0048] The bracket 9 is fixed in the structure B by welding;

[0049] The pry bar sleeve 8 is an L-shaped rod; the inflection point of the L-shaped rod is connected to the bracket 9 through a bolt, and the pry bar sleeve 8 can rotate around the axis of the bolt;

[0050] One end of the pull rod 7 is pin-connected with one end of the pry bar sleeve 8; when the other end of the pry bar sleeve 8 is pulled, the pry bar sleeve 8 rotates around the axis of the bolt, thereby driving the position of the pull rod 7 to change;

[0051] The other end of the pull rod 7 is pin-connected with one end of the fixing pin 6; the fixing pin 6 is arranged in the vertical direction; the other end of the fixing pin 6 extends into the guide sleeve of the second double-ear seat 10, and the guide sleeve is used to guide the movement of the fixing pin 6 so that it can enter or extend out of the through hole B of the second double-ear seat 10;

[0052] When the fixing pin 6 is in the storage position, the fixing pin 6 does not enter the through hole B of the second double-ear seat 10; when the fixing pin 6 is in the working position, the fixing pin 6 enters the through hole B of the second double-ear seat 10;

[0053] Working principle:

[0054] When the connection operation conditions between the structure A and the structure B are not met, that is, the transmission mechanism and the pry mechanism are not connected, the transmission fork 4 is in the storage position, the ear plate 1 is located in the structure A; the fixing pin 6 does not enter between the two ears of the second double-ear seat 10;

[0055] When the connection operation conditions are met between structure A and structure B, that is, the transmission mechanism and the pry mechanism are connected, first, a special tool is inserted into the transmission fork 4 to move the transmission fork 4 to drive the transmission shaft 3 to rotate, thereby driving the ear plate 1 to rotate horizontally out of the structure A; the end of the ear plate 1 extending out of the structure A extends between the two ears of the second double-ear seat 10, and the connection hole B of the ear plate 1 is coaxial with the through hole B of the second double-ear seat 10; at this time, the transmission fork 4 rotates to the working position, and the position of the transmission fork 4 is limited and locked by the limit device 5 to prevent the position of the ear plate 1 from changing;

[0056] Then, insert the special tool into the pry bar sleeve 8 and press it downward. By pulling the pry bar sleeve 8, the position of the pull rod 7 is changed, and then the fixing pin 6 is driven to move axially along the guide sleeve, that is, the rotational movement of the pry bar sleeve 8 is converted into the linear movement of the fixing pin 6, so that the fixing pin 6 falls vertically and enters the through hole B and the connecting hole B, thereby realizing the connection between the ear plate 1 and the fixing pin B; then the transmission mechanism and the pry bar mechanism are connected; finally, the connection between the structure A and the structure B is realized.

[0057] The end of the ear plate 1 extending from the structure A extends between the two ears of the second double-ear seat 10, and the connecting hole B of the ear plate 1 is coaxial with the through hole B of the second double-ear seat 10; the fixing pin 6 passes through the through hole B and the connecting hole B to achieve the connection between the ear plate 1 and the fixing pin B; thereby achieving the connection between the transmission mechanism and the pry rod mechanism;
