Abstract
The utility model discloses a bracket for a truss-structured fly jib of an autocrane. The bracket comprises a casing connected with a cross bar at the top of a first-section truss of the fly jib, the casing is fixedly connected with one end of a long bar, the other end of the long bar is fixedly connected with a support plate, the support plate is provided with a pin hole, the bracket also comprises a hoop arranged on a cross bar at the middle part of the first-section truss, and a support plate inserted pin is fixedly connected to the hoop. When a main jib is connected with the fly jib, a support plate shaft pin is pulled away, the long bar is automatically perpendicular, the support plate is supported on the ground, and a connecting buckle at the tail part of the truss and a connecting lug of the main jib are accurately aligned, so that the shaft pin is conveniently inserted in the connecting buckle and the connecting lug without manual lifting operation or other support components, then the long bar is uplifted, and the support plate inserted pin is inserted in a pin hole of the support plate, thereby facilitating the application or withdrawing of the fly jib. Under the premise that the original truss structure is not changed, the bracket disclosed by the utility model has the characteristics of simple structure, labor saving, and convenient connection between the main jib and the fly jib.
Description
Technical field
The utility model relates to a kind of auxiliary of hoisting crane, is specifically related to a kind of carriage of car hosit truss structure auxiliary.
Background technology
Car hosit is a kind of hoisting crane that is contained on general-utility car chassis or cars chassis, and its travel operator's compartment and lifting control cabin divide and be arranged.The manoevreability of car hosit is good, shifts rapidly.Tonnage automobile crane is comprised of principal arm and the auxiliary of multi-joint telescoping substantially.When the height of principal arm can not meet requirements, can connect auxiliary at the end of principal arm, reach the purpose that promotes object toward eminence.Auxiliary can only promote lighter object.Auxiliary is generally a joint arm or two above folding auxiliary arm or the telescopic auxiliarys of joint, and is wherein common with folding truss structure auxiliary.
The first segment truss two sides of tail of truss structure auxiliary respectively is provided with two junction buttons, and the front end both sides of principal arm respectively are provided with two engaging lugs, and junction button is connected by pivot pin with engaging lug, shape such as hinge.Easy sagging dislocation when opening due to auxiliary, so car hosit all leans on the artificial contraposition that holds up when principal arm is connected with auxiliary, very inconvenient.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of principal arm is connected easy car hosit truss structure auxiliary with auxiliary carriage.
For solving the problems of the technologies described above, the carriage of the utility model car hosit truss structure auxiliary, comprise the sleeve pipe that is connected with auxiliary first segment truss top cross bar, sleeve pipe is captiveed joint with an end of stock, the other end of stock is captiveed joint with fagging, fagging is provided with pin-and-hole, also comprises the clip that is arranged on the cross bar of first segment truss middle part, is fixedly connected with the fagging latch on clip.
The upper end of described fagging is crooked, and described fagging latch is resilient latches.
Due to technique scheme mounting sleeve on the top cross bar of auxiliary first segment truss, be connected with the stock that is provided with fagging on sleeve pipe, when principal arm is connected with auxiliary, pull open the fagging pivot pin, the stock automatic vertical, fagging supports ground, and the engaging lug accurate contraposition of the junction button of truss afterbody and principal arm does not need manually to lift or other strut members, just pivot pin is inserted in junction button and engaging lug easily, lift again stock, the fagging latch is inserted in the pin-and-hole of fagging, facilitate auxiliary to use or regain.Therefore, the utility model has simple in structure, laborsaving, principal arm and is connected easy characteristics with auxiliary under the prerequisite that does not change former truss structure.
Description of drawings
Fig. 1 is the carrier structure schematic diagram of the utility model car hosit truss structure auxiliary
Fig. 2 is the upward view of embodiment shown in Figure 1;
Fig. 3 is the retracted state schematic diagram of embodiment shown in Figure 1;
Fig. 4 is the working state schematic representation of embodiment shown in Figure 1.
The specific embodiment
By Fig. 1, Fig. 2 as seen, the carriage of the utility model car hosit truss structure auxiliary, comprise the sleeve pipe 3 that is connected with auxiliary first segment truss 1 top cross bar 2, sleeve pipe 3 is captiveed joint with an end of stock 4, the other end of stock 4 is captiveed joint with fagging 5, fagging 5 is provided with pin-and-hole, also comprises the clip 7 that is arranged on first segment truss 1 middle part cross bar 6, is fixedly connected with fagging latch 8 on clip 7.Top cross bar 2 is suitable to the length of the span of middle part cross bar 6 and stock 4.
For convenience of the automatic insertion of fagging pivot pin 8, the upper end of fagging 5 is crooked, change fagging latch 8 into resilient latches, resilient latches can be made by oneself, also can buy.
Referring to Fig. 3 and Fig. 4, first the junction button 19 with this side truss afterbody is connected with the engaging lug 10 use pivot pins of principal arm, shift out auxiliary to principal arm in line, pull open fagging pivot pin 8, stock 4 automatic verticals, manipulating crane makes fagging 5 be supported in ground, the junction button 9 of opposite side and engaging lug 10 position alignment, be connected firmly with pivot pin, then stock 4 is lifted, the curved end of fagging 5 ejects resilient latches, during to pin-and-hole, resilient latches is inserted in pin-and-hole, and this moment, auxiliary can use.
