Abstract
The utility model provides a detachable connection structure of a boom bracket and an underframe of a truck crane. The root of the boom bracket is detachably connected with a fixing plate welded on the underframe, and the detachable connection is bolted connection. The boom bracket comprises stringers, beams connected with the stringers, an upper support, a supporting plate positioned at the upper ends of the stringers, and a rubber cushion pad which is fixedly arranged on the inner tilting surface of the supporting plate through screws. The root of the boom bracket is detachably connected with the fixing plate welded on the underframe, accordingly, when the shot derusting and other working procedures of the boom bracket are needed, the boom bracket can be removed from the underframe, so that the process operation of the boom bracket can be facilitated.
Description
Technical field
The utility model relates to a kind of car hosit, is specifically related to the connection structure of a kind of car hosit arm support and underframe.
Background technology
Car hosit is a kind of hoisting crane that is contained on general-utility car chassis or the cars chassis, has the good performance of manoevreability.The arm support of car hosit be arm be in go or non-hoisting operation state under support the member of arm, existing arm support root is fixed with the underframe welding, is on-dismountable connection.Because arm support and underframe welding are integrative-structure, and be bulky, can't carry out operations such as shot peening.
Summary of the invention
The technical matters that the utility model will solve provides the detachable draw bail of a kind of car hosit arm support and underframe.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is:
The adapter plate that welds on the connection structure of a kind of car hosit arm support and underframe, said arm support root and underframe detachably connects.
The connection structure of above-mentioned car hosit arm support and underframe, said detachable connection is a Bolt Connection.
The connection structure of above-mentioned car hosit arm support and underframe, said arm support comprise longeron, connect the crossbeam of longeron, on support, be positioned at the supporting plate of longeron upper end and through the rubber buffer of screw retention on supporting plate introversion face.
The adapter plate that welds on arm support root and the underframe detachably connects, and the arm support is carried out operation such as shot peening when needs when handling, and can disassemble from underframe, is convenient to its technological operation.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation:
Fig. 1 is the structural representation of arm support.
Fig. 2 is the connection structure scheme drawing of arm support and underframe among Fig. 1.
Fig. 3 is the structural representation of Fig. 1 middle and upper part.
Among the figure: 1 arm support, 2 longerons, 3 crossbeams support 5 rubber buffers, 6 screws, 7 adapter plates, 8 bolts, 9 supporting plates on 4.
The specific embodiment
As shown in figures 1 and 3; Car hosit arm support by longeron 2, crossbeam 3, on support 4 and welding such as supporting plate 9 be integrative-structure; Rubber buffer 5 is fixed on through screw 6 on the introversion face of supporting plate 9; Hoisting crane is going or during non-hoisting operation state, arm is pressed on the arm stent bearing plank, and rubber buffer plays buffer action.
Because the welding of existing arm support root and underframe is fixing, is on-dismountable connection, cause bulkyly, can't carry out operation processing such as shot peening.Therefore; The utility model is improved to detachable the connection with arm support root with the connecting mode of underframe; Fig. 2 shows the connection structure of a kind of car hosit arm support and underframe, and the adapter plate 7 that welds on said arm support 1 root and the underframe detachably connects.Said detachable connection is that bolt 8 connects.
Claims (3)
1. the connection structure of car hosit arm support and underframe is characterized in that: the adapter plate that welds on said arm support root and the underframe detachably connects.
2. the connection structure of car hosit arm support according to claim 1 and underframe is characterized in that: said detachable connection is a Bolt Connection.
3. the connection structure of car hosit arm support according to claim 1 and underframe is characterized in that: said arm support comprises longeron, connects the crossbeam of longeron, on support, be positioned at the supporting plate of longeron upper end and through the rubber buffer of screw retention on supporting plate introversion face.
