Problems solved by technology
Since the connection between the balance arm of the tower crane, the boom and the tower cap is usually completed at high altitude, this traditional installation method often encounters the problem that the pin holes on the ear plate are not easy to align when assembling in the air, and The connecting pin itself has a large diameter and a long length, and it is not easy to knock into the pin hole, which makes it difficult to assemble and disassemble the balance arm and lifting arm
In addition, the operation method of beating the pin shaft for a long time at high altitude also has potential safety hazards.

Embodiment Construction
[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0022] see Figure 1 to Figure 5 , shows the structure of the connector provided by the embodiment of the present invention. In this embodiment, the connector is applied to a tower crane as an example. As shown in the figure, the connector includes: a movable clamping plate 1, a fixed seat 2 , Operating shaft 3 and positioning pin 4.
[0023] Specifically, the movable clamp 1 is provided with a first opening installation groove 11 and a first pin hole 12 , and the operating shaft 3 is connected with the movable clamp 1 . The fixed seat 2 can be connected with the tower cap 93 of the tower crane or has an integrated structure with the tower cap 93 of the tower crane. The fixed seat 2 is provid...

The invention provides a connector and an engineering machine. The connector comprises a movable clamping plate, a fixing base, an operating shaft and a positioning pin. A first open installation groove and a first pin hole are formed in the movable clamping plate. The operating shaft is connected with the movable clamping plate. A second open installation groove, a first open clamping groove, a second open clamping groove and a second pin hole are formed in the fixing base. The operating shaft can be switched to be clamped in the first open clamping groove or the second open clamping groove. When the operating shaft is connected into the first open clamping groove in a clamped mode, the first open installation groove and the second open installation groove are separated; and when the operating shaft is connected into the second open clamping groove in a connected mode, the positioning pin is inserted into the first pin hole and the second pin hole opposite to the first pin hole, so that the first open installation groove and the second open installation groove are made to be close to each other so as to form a pin hole used for installing a connecting pin. According to the connector, the assembly and disassembly difficulty between other connecting pieces and the connector can be lowered.
Description
technical field [0001] The invention relates to the field of engineering machinery, and more specifically, to a connector and an engineering machinery. Background technique [0002] Tower crane, also known as tower crane, is a kind of high-altitude lifting equipment mainly used for construction. The main structure of the tower crane includes the tower body, the lifting arm and the balance arm connected to the tower cap on the tower body, etc. At present, the connection method between the balance arm, the boom and the tower cap is mainly to adopt the lug pin structure, that is, a single lug or double lug structure is set on the tower cap, and a corresponding lug structure is set on the balance arm and the jib. Double lug structure or single lug structure, by connecting the lugs on the balance arm and the lifting arm with the lugs on the tower cap, and inserting the connecting pin shaft into the pin hole on the lug, the balance arm and the lug are completed. Assembly of the j...
