Abstract
A slewing tower and slewing upper bearer connection structure is characterized in that the slewing tower and slewing upper bearer connection structure comprises a slewing tower, slewing tower rods A, longitudinal pins, connection pins A, a slewing upper bearer, slewing tower diagonal web members, connection pins B and slewing tower rods B, the slewing tower rods A on the slewing tower are connected with the slewing upper bearer through the longitudinal pins and the connection pins A, the slewing tower rods B on the slewing tower are connected with the slewing upper bearer through the connection pins B, and the slewing tower diagonal web members are connected between the slewing tower rods A and the slewing tower rods B. The slewing tower and slewing upper bearer connection structure can effectively prevent the whole slewing tower and the upper portion of a tower crane from wholly slipping, and can also effectively improve the running stability and safety of the tower crane.
Description
Technical field
The present invention relates to the connection structure of tower crane rotation body of the tower and revolution upper bracket.
Background technology
Tower crane rotation body of the tower on the market generally all adopts high strength bolt or bearing pin to be connected with the revolution upper bracket at present.High strength bolt must guarantee evenly bearing load of every bolt when connecting, control gets up to acquire a certain degree of difficulty like this, and is more loaded down with trivial details when adopting high strength bolt to be connected mounting or dismounting simultaneously; Four bearing pins that are arranged in parallel are all adopted in the bearing pin connection, when doing the revolution operation, the tower machine is easy to generate slewing tower along the axial slip that connects bearing pin, cause the revolution of tower machine to rock bigger, part tower machine product adopts the bearing pin that is arranged in parallel to add longitudinally, and locating dowel pin solves such problem, but this method is made complicated, difficulty of processing is big, and production technology is had relatively high expectations.
Summary of the invention
In order to overcome above-mentioned tower crane rotation body of the tower and the problem that the revolution upper bracket is connected, the invention provides the connection structure of a kind of slewing tower and revolution upper bracket.
The connection structure of a kind of slewing tower and revolution upper bracket, it comprises slewing tower, slewing tower master string A, vertical pin, connection bearing pin A, revolution upper bracket, slewing tower diagonal web member, connects bearing pin B, slewing tower master string B, slewing tower master string A on the slewing tower is connected with the revolution upper bracket by vertical pin, connection bearing pin A, slewing tower master string B on the slewing tower is connected with the revolution upper bracket by connecting bearing pin B, and the slewing tower diagonal web member connects between slewing tower master string A and the slewing tower master string B.
Slewing tower is to be connected the mode that still adopts bearing pin with the connection structure of revolution upper bracket, but the bearing pin on the four points of connection is the cycle arrangement of square crossing; Its diagonal web member of the bearing pin junction of slewing tower lower end selects to be supported on vertical connecting pin shaft position simultaneously, becomes a cantilever end with another root main chord on the one side.
The technical solution adopted for the present invention to solve the technical problems is: the ear seat that the tower crane rotation upper bracket is connected with slewing tower is configured to orthogonal bearing pin connection mode in same plane, the pin shaft hole of slewing tower matches with the pin shaft hole of upper bracket, and arrange the vertical pin of bearing pin in the outside of upper bracket ear seat, prevent that bearing pin produces axial slip in the work of tower machine, like this because a bearing pin is always arranged on the one side in office is that the restriction slewing tower is along another bearing pin axial slip, just can guarantee effectively that whole slewing tower and tower machine upper can not produce the integral slipping phenomenon, also just can effectively improve operation stability and the safety of tower machine.
Description of drawings
Fig. 1 is the connection diagram of tower crane rotation upper bracket and slewing tower;
Diagram: 1, slewing tower; 2, slewing tower master string A; 3, vertical pin; 4, connect bearing pin A; 5, revolution upper bracket; 6, slewing tower diagonal web member; 7, connect bearing pin B; 8, slewing tower master string B.
The specific embodiment
Further specify below in conjunction with accompanying drawing:
As shown in Figure 1, the connection structure of a kind of slewing tower and revolution upper bracket, connect bearing pin A 4 and be connected 90 ° of connections of bearing pin B 7 intersections, when slewing tower master string A 2 edges connect bearing pin A 4 axial slips, connect bearing pin B7 and can stop whole slewing tower to turn round the upper bracket slippage relatively; Because all adopting this layout pattern on each face of slewing tower, just can guarantee effectively that slewing tower can reach such effect in any direction.Junction below slewing tower on this face, slewing tower diagonal web member 6 selects to be supported on the position of vertical connection bearing pin B7, can provide the actv. strength and stiffness to guarantee when slewing tower master string B8 offsets slewing tower along connection bearing pin A4 slippage; Slewing tower master string A2 lower end does not have diagonal web member to arrange simultaneously, make it become a cantilever end, allow it that certain elastic deformation is arranged when mounted, with manufacture difficulty and the manufacturability requirement that reduces whole slewing tower, improve the property easy for installation of revolution upper bracket and slewing tower.
Claims (1)
1. the connection structure of a slewing tower and revolution upper bracket, it is characterized in that: comprise slewing tower, slewing tower master string A, vertical pin, connection bearing pin A, revolution upper bracket, slewing tower diagonal web member, connect bearing pin B, slewing tower master string B, slewing tower master string A on the slewing tower is connected with the revolution upper bracket by vertical pin, connection bearing pin A, slewing tower master string B on the slewing tower is connected with the revolution upper bracket by connecting bearing pin B, and the slewing tower diagonal web member connects between slewing tower master string A and the slewing tower master string B.
